We went to the Advanced Data Science training Course on August 1st and 2nd. 
First, on the first day we went to Tokyo Institute of Technology and the Tokyo University of Technology’s Institute of Industrial Science.  At Tokyo Institute of Technology, we received training on how to use tools and knowledge to infer unknown object.  We were able to work together and discuss which tools use and we think how to open the object of all.
Next, at the Tokyo University of Technology’s Institute of Industrial Science, we visited two research laboratories.  We were able to learn about technologies, such as AI, Robots, and electricity.  It will make our lives more convenient, and I think it gave us an opportunity to rethink our own lives.
On the second day, we visited the laboratory of statistical mathematics and True Data Inc.
At the laboratory of statistical mathematics, we got to see the latest technology on account of their supercomputers, as well as learn about the history of computers thanks to the old computers they have on display.  At True Data Inc, we used the software “Urecon” to search trends of product sales. We were able to learn how to use data properly.
This training was a great experience for us.　( 209  Iwata Suzuma , Katsuta Aruha)

On July 30, 2024, A total of 18 people from 4 groups participated in the Nikkei STEAM Symposium held in Osaka.
Having participated in an online workshop since April, we worked on this presentation from scratch and completed it. 　　While we were having trouble deciding on the theme, we did a lot of research and thought about the content, figured out the story, and worked together as a group.　　We were inspired by the high-level presentations made by fellow high school students. 　　After the repairs the day before, we traveled by bus and stayed the night before. 　　On the day of the event, we participated all day from the morning until the closing ceremony in the evening.
We stayed the night after and traveled by bus for 5 hours, which made us tired, but I believe it was a very meaningful activity.　
My impression：　I participated in the Student Summit - Future Earth Conference. It was a good opportunity to think about the current state of the global environment and the possibilities for the future from various perspectives, giving us a sense of crisis.
On that day, I had the valuable experience of an intense five minutes presenting in front of a large audience. ( 205 　Mukai　Yuka)

　On July 28th, we participated in the primary-round of the WRO, World Robot Orimpiad held during the summer vacation.  The theme was “disaster and recovery robots”.  Jobs such as restoring bridges, moving objects are very important.  Because Minami High School was participating for the first time and had little experience, we unfortunately weren’t able to pass through the round.　
　The experience of working and thinking together, making and programming robots across different grades, departures and teams, were irreplaceable!  For the next year’s WRO, we hope to use what we learned to achieve better results. (209  MIYOSHI )

　On July 26th, the lecture was held with an analysis tool, “Dolphin Eye”, by Corp. True Data.  We can grasp the consumption tendency through the purchase data. 
In today’s presentation we learned how to get true data from huge amounts of data.
In the workshop, we used the sales data of everyday items to find differences compared to other items.
     I want to make use of the skill to solve everyday problems that I learned this presentation.（305  OZAWA Takuma,  YANO Kose）

　　On Thursday, July 25th, we held a workshop for elementary school students, ”Programming Class: Let’s Try Programming with LEGO Blocks!”, in collaboration with Ehime University’s Data Science Center.
This time, 30 elementary school students from Matsuyama City participated.  During the workshop, they built a cleaning robot using LEGO® Education SPIKE™ Prime.  They used sensors and devised a program to enable the robot to clean without falling off the desk.  All groups worked together to move the robots and complete the cleaning.
      Thank you to all the children who took part.  I would be happy if this experience can further their interest in programming and robots.　(University Student Assistant HIGASHINO)

We gave a presentation to junior high school students on how to conduct Science research projects. 　I talked about the change in the sound of the writing pad when flipped. 　The junior high school students listened very earnestly and asked lots of questions, which was great.

　We took lectures on how to generate business ideas. 　What impressed me most was about advertising.　 I learned the importance of narrowing down the target audience. 　By doing so, the services and the market size become clear. 　When I actually thought of it that way, it became easier to think of an effective advertising method for the target audience.

　It was interesting to think that the services we usually use are thought of in this way. Thank you very much for your valuable lecture!　(204 Akase Manami)

   Five members from the Natural Science Club (formerly the Physics Club) who created a diorama of Matsuyama Castle received a letter of appreciation from Matsuyama Mayor Katsuhito Noshi. The diorama was created to provide a clue for the visually impaired to obtain information on the shape of Matsuyama Castle through the sense of touch. It will be loaned to students on school trips to special needs schools visiting Matsuyama in the future.

Mayor NOSHI is also an alumnus of our school, and he told current students, “Make your classes count,” and “Don't say ‘I can’t do it anyway...’ because it reduces your potential!” He gave us a passionate message. Encouraged by this message, all students, faculty and staff will continue to devote themselves to their future school life.（209 Tomoi）

On April.6^th, at Saijyo Senior High School, we presented at a competition as our first SSH activity of this year.  The third-year students in the science and mathematics course announced their research results and communicated with other schools' students.  We will make use of this experience.

I was able to learn various opinions and perspectives through this experience. I think this can be useful for not only research but also everyday life. (209 Okamura)

The Physics club has worked on a project to create a diorama of Matsuyama Castle, and has completed a prototype of the diorama.  This was produced by the request of Matsuyama City as an educational material to introduce Matsuyama Castle to visually impaired students visiting Matsuyama.  This time, we had people from Matsuyama blind school actually touch the product and give us their opinions. ■

 I was happy to receive a feedback that it made them want to visit Matsuyama Castle again.  We would like to improve and complete the castle. 　(209HR Tomoi Ayato)

We participated in Ehime Science Challenge 2024 on February 4th at Ehime University. There, we summarized and presented our research results using posters and listened to presentations by students from other schools.  It was a very good experience.

   We won the Prefectural Governor's Award at the Japan Student Science Award Ehime Prefecture Competition and participated in the central final examination! December 17, 2023, 19:00 Kojo Research Institute, a third-year science and mathematics student, submitted an item to the Japan Student Science Award. However, at the Ehime Prefectural Tournament, he won the Prefectural Governor's Award and was selected to participate in the  central Tournament. In addition, I was selected as a representative at the central preliminary examination (document examination) held on November 12th, and participated in the central final examination (remote) held on the 17th. For the central final examination, participants were required to submit in advance a video summarizing their enormous research results into a 5-minute presentation with about 10 slides, and after the regular examination, they had to work hard to prepare the video while preparing for the personal exam. The question-and-answer session on the 17th required a lot of patience, as rigorous answers were required regarding the investigation of previous research, the validity of the model in model experiments, understanding of theoretical formulas, and comparisons with experimental values. However, we were able to somehow answer the question based on our experimental experience and knowledge. One of the students who participated said, ``Although it was a very tough question and answer session with lots of tough questions, I was happy that they asked questions after fully understanding our research, and it was a fun time.'' I got it. This marks the end of this research group's research activities. Although this is a difficult time, I hope that you will do your best to realize your career path.

The Kojo research group was awarded the first prize in the central final screening of the Japan Student Science Award.

   In a cooperative class between Ehime University and our high school,  first- and second-year students from the science and mathematics department attended lectures and laboratory tours.

   Lecturer: Dr. Yuko Kamika (Associate Professor, Department of Food Production Science, Graduate School of Agriculture, Ehime University)

Content:

(1) Observing the sorting of tomatoes harvested at a plant factory

(2) Collecting data sorted by a sorting machine

(3) Significant difference test using individual weight data (lecture and exercise at the Media Hall of the Center for Information Technology)

   First, we visited a solar-powered plant factory. Tomatoes were grown in a tall plant factory with glass walls, different from ordinary plastic greenhouses. The tomatoes were planted not in the soil but rather in rock wool and hung from above, making it look more like a "factory"  than a "field”. By controlling the plants’ growing environment, they are able to supply farm products at stable prices and quality throughout the year.

   Next, we also observed the sorting of harvested tomatoes by weight.

   After the tour, the students moved to the Information Media Center, where they had a lecture on significance tests while doing exercises using spreadsheet software.

   I had a hands-on experience at the Wang Ding Time Science and Art Experience Hall and Ya Dong University of Science and Technology.

   I gave a presentation on Sound Power Generation with Plastic Parabolas and Resonance Tubes at an international forum and had a lot of fun interacting with people from different countries. 

   At New Taipei Municipal Yingee Vocational High School, I participated in Japanese language classes and learned about ceramics. I was able to make friends with the students who were not so familiar with each other and interacted with them a lot.  My host family was very kind to me and I was able to spend a fulfilling week in Taiwan.

   I feel that spending a week long time in Taiwan was a great experience. It was very difficult to deliver a 10-minute presentation in front of presenters from various countries, and I realized how poor my English skills were. However, I gradually became able to communicate in English, and I think I have grown as a result.

   The Taiwanese people were really kind to us and we became such good friends that we still keep in touch with them. I miss them very much. ( 209 Rua HONDA )

　On the second day, we went to Tokyo to visit the Institute of statistical Mathematics and true data, Inc. At the Institute of statistical Mathematics, Dr. Miyasato first gave an overview of the institute and we toured the facilities.  Then, Dr. Mchihashi introduced his study on “Modeling Evaluation of Tanka” We learned the importance of considering “invisible data” and modeling it mathematically.

     At true data Inc. Dr. Toyama gave a “practical workshop on Data Analysis Vitalizing URECON” Each group researched and discussed products of interest to us.  Then summarized and presented our findings.

     Through these seminars, the participants experienced more practical things about data analysis and STEM education.  We will continue to hone our skills to apply the knowledge we learned this time to our future research projects, career exploration, and other activities.

  I learned a lot about how to handle data. I would like to refer back to this as I handle data in my own studies.   ( 209 Kameoka Mayu )

In this training, 2nd and 3rd year students visited universities and companies in the Kanto region for two days starting August 1st.

On the first day, we visited Tokyo Institute of Technology and the Institute of Industrial Science, the University of Tokyo.　　In the former, in Professor Nagahara's workshop, each group made a hypothesis, measured it, and considered about what it could be expected mathematically through these results.

In the latter, we took a lecture about STEM education, scientific and technical communication,　astrophysics and neutrinos.

After that we visited several facilities and used an educational app developed by  graduate students to consider how it worked.

Both were very interesting and exciting for us.

On Friday, July 21, a hands-on programming class was held at the Media Hall in Ehime University's Comprehensive Information and Media Center. 　Twenty-five elementary school students from Matsuyama City participated in the class and experienced programming using LEGO Education SPIKE Prime.

The school's ICT education support staff and STEAM education support staff served as instructors, and two Ehime University students, who work as school supporters , and 16 first- and second-year students from the school supported the elementary school students as teaching assistants. 　First, the students created their own robot cars with LEGO bricks, programmed them using the SPIKE software, and gave them a test drive. 　Next, they improved the robot car by using gear parts to make it run faster, and finally, everyone competed in a robot car race.

Thank you to all the students who participated in the event. We hope that this event will spark your interest in programming and robot.

 　All of the children in this hands-on class were interested in programming, and they immediately put into practice what we taught them, such as how to move forward and how to make it faster, which we enjoyed.

　 STEAM Symposium, which Nikkei Newspaper hosted is held in Osaka International Exchange Centre.  15 students in three groups took part in a three-month online workshop since April.  As ‘Cheers!’ we worked together to make presentations with the advice of university student supporters and business people working in the field.

    Five third-year students took part in “Student summit ~Future Earth Conference~” which suggested ways to protect future earth.  Five third-year regular course students took part in a “Poster session,” which let them experience the hypothesis Testing Cycle.  Five second-year regular course students took part in the “DIS steam seminar,” which suggested ways to use ICT in educational facilities.

    We left the school at 6:30 am on July the 19th by bus.  We started research as soon as we arrived.  It was very busy, with the closing ceremony at 4:30pm.  But we were able to learn through the presentations of various people. Business people and people involved in the Osaka Expo were invited as judges.  The thigs pointed out were instructive.  The many presentations were easy to understand, and they taught us a lot of techniques.  We were only able to attend this for half a day, but it was very fulfilling.

   The result of this was that we won the best prizes in ‘DIS steam seminar’.  We received compliments on our presentation.  This encouraged us for our future research in Data Science Ⅱ.  It was hard work, but it was very meaningful.       (205HR TAKAHASHI Yusuke)

On June 16^th,a cultural lecture for high school students was given by a manga artist, Mr.Shinichi Sakamoto, “In search of your manga expression.”  He is a sincere person, passionate and dedicated to research. He talked about his success and setbacks in his life of loving manga, and his passion conveyed to students' hearts.  There wasn't enough time for every student to inquire about everything he had experienced or advices during the question and answer session.  It was a meaningful lecture for students.  Our school positioned this lecture as the "A:Art" of STEAM education and conducted it as a STEAM  lecture.  The students were able to learn from Mr.Sakamoto, who also has airs of being a researcher, about “a heart that loves research” and “the importance of continuing to gather data without fear of failure.”

When I attended the lecture, I realized I want to find something that I can absorb myself in.    (204  Kuroda Sara)

　For 3 days from December 6th, 40 science and mathematics students took part in the event "Kansai Training." 　We did our best towards these fulfilling activities: 

Attend a Seminar at the Museum of Nature and Human Activities, Hyogo 

Communicate using Lego SPIKE at Hyogo Prefectural Kahogawa Higashi High School 

Communicate with alumni over Zoom.

The most interesting part of the day was the visit to Kakogana Higashi High School. The students at that school were also science and mathematics students, just like us, so we were able to discuss our respective research on the same wavelength, giving us hints for our own research, and a boost to our motivation.

On the second day of the training, we went to Osaka.

Specifically, the Research Center for Nuclear Physics, Osaka University, and the Bio-history Research Hall at the Osaka Science Museum.

At the research facility, we were able to observe the latest technology of Japan. Also, because we were able to get a closer-than-usual look at the university's facilities, we were able to see a place we often go to in a new light.

On The third day,  we're a little sad to think that today is the last day, but we'll do our best to make the most of it, and learn a lot. 

Bando Kobe Science Museum

"SPring 8"(Super Photon ring @ 8 GeV) and "SACLA" (SPring-8 Angstrom Compact free electron LAser) 

We were able to learn about many of Japan's latest technologies. In addition, we were able to learn about the challenges and rewards of working as a researcher from the stories of people involved in the research there.

   On October 19th and 20th, I participated in the High School Students Summit convention on “World Tsunami Awareness Day” 2022 for 2 days.  It was held at the Toki Messe in Niigata city. In the breakout sessions, we shared our opinions on the theme “Disaster Risk Reduction” and discussed it together, In addition, I gave a presentation whose title was “Fabrication of seismic isolation rubber which can be used for furniture.”  I made a lot of friends, including international students, and played a role in a commemorative tree planting.  Through this summit, my awareness of disasters and measures against them increased. I had a wonderful time. ■（OZAKI Yuka　109）
            

Waipahu High School in Hawaii, Uwajima Higashi High School, and ourschool have been conducting an international joint research project on waterpurification since last year.  This time,the progress of research in the three schools was mutually presented andconfirmed.   In this school, we tried tofabricate a variety of filtration devices and determined the performance of thedevices through pack tests.   Inaddition, Uwajima Higashi High School and Waipahu High School reported on theirefforts to purify rivers using oyster shells and native Hawaiian plants “Akulikuli”,respectively.   And then, we have a lively exchange of ideas.　

Auther’s opinion:  At the third exchange meeting, the studentsbecame accustomed to asking questions in English and were able to interactactively.  I would like to continue to domy best with them. 209―Kaito Matsutomo
      

   First and second grade students of our science and mathematics class took part in the Super High School Consortium on Friday, January 28th.
   The group “Negibou's” was the representative for assignments from second grade students, and gave a presentation that we are working on a daily basis at SSH with students from other schools. Also, we exchanged opinions and hold a question-and-answer session. We received many opinions, comments and questions from other school's students, which solved as food for thought fir future research.
In addition, another student of the science and mathematics class gave presentations about efforts to revitalize the local industry of high school students in the Chuyo region, in the middle part of Ehime Prefecture, efforts regarding the Under-15 Job Challenge of junior high school students and so on along with an exchange of opinions.
   Students of the science and mathematics class were able gain valuable experience that broadened them horizons using presentations from different fields through exchange of other school's students in this consortium.

Author’s Opinion: I think　I was able to grow through interaction with people I am usually unable to get involved with. I would like to make use of this experience and continue to enjoy my research.  209 Sae SHINGU
     

   First grade students took part in a science workshop at school on the 27th January, 2022, inviting Dr. Sebastian Ritterbex, a Postdoctoral Research Fellow in Theoretical and Computational Mineral Physics in Geodynamics Research Center of Ehime University. The research titles were as follows; “Research on the properties of tiles”, “Research on dyes of Ginkgo biloba”, and “Improving the Convenience of Flywheel-Based Wind Power Generation”
 
   Three groups made their presentations in English clearly and logically, which were splendid and quite impressive, and received high praise from participating researchers. It is hoped that students will make good use of today's experience so that it could become the foundation for the upcoming research events that students are expected to join this spring. Also, the students worked as moderators managed the workshop very smoothly so as to make it lively and productive. We are really proud of our students for their hard work and for today's success. We hope that students will keep up their good work and grow into prospective young researchers with brilliant scientific minds. 

We would like to express our sincere gratitude to Dr. Sebastian Ritterbex, for his advice and support to our workshop. ■

Student’s Impression:
   We started presentations for our preparation later than intended, so we thought we wouldn’t be able to make it in time, but in the end we managed it. Also, since it was the first presentation we’ve ever given, we were very nervous, but we are glad to have been praised by so many teachers.
We appreciated the opportunity to announce our research to the audience. ~ NINOMIYA and HINO, Class 109
       

      On January 9th, the program "Space: The Ultimate Field Trip" (Space Engineering, Life in Space, etc.) was hosted at our school in collaboration with the Director of the Space Research Institute Grant Consortium at the University of Hawaii, Art Kimura and Rene Kimura. This year, we invited Miyazaki Prefectural Nobeoka High School and Yamaguchi Prefectural Shimonoseki West High School, and we three schools all took part in the program.

      From our school, 37 students from the 1st and 2nd grades of the regular courses and science and mathematics courses participated. Mr. Kimura explained the extraordinary and mysterious phenomena that occur when living in space in an easy-to-understand manner using demonstrations of scientific experiments. Although tending to seem difficult at first glance, learning about and understanding these mysterious phenomena is essential for the intellectual profession and space development technology, and life in space is established by applying basic scientific concepts as well as familiar technologies. We were able to see space in an up-close-and-personal way.

      After Mr. Art Kimura's presentation, a question and answer session on space was held, and all three schools asked questions about life in space. We students learned freely about life in space and the latest space-related news, along with a question-and-answer session held in English. Art Kimura praised us for the questions we asked. Through this initiative, we were able to strongly experience the contentment of grappling with challenges.■

Author’s Impression: It was interesting that the technology necessary for space development was already familiar to our lives.  So, I came to realize that the technology we know and regularly use can be useful for other things, and the technology we don't know how to use can be useful for almost anything.　209.

　As part of extracurricular lessons “Science Club” of the target science and mathematics first grade, the second training support science and mathematics teacher program was held. This program is a chance for students to promote future science and mathematics education, to get science and mathematics first grade students more interested in science, and for the program to become a place of learning for both students and teachers.
　Continuing from the first event in November, the topic of this second event was conducting experiments. The students discussed discoloration of anthocyanin from pancake mix ingredients. Since this time was a training session, we used pancakes prepared in advance, but next time let’s make pancakes with blueberry jam at home! ■
Author’s opinion: “This training was the first time I learned using food, which was a fresh experience.” ~ Keita MIYOSHI
            

　The advanced science training ~first day~
First year students of our department of science experienced this training. We were studying advanced science based on the theme of SSH. We report on this activity. We’ll make use of this experience and knowledge for research and finding our way in life.
〈first day 12/13: Shikoku Seiyo Geopark de STEAM (Science, Technology, Engineering, Art and Mathematics)〉
　Shikoku Seiyo Geopark is a “Park of Earth” which has four hundred million years of history. The purposes of this park are conservation, education and geotourism. Students of our department of science don’t study geology, but we got to know the earth science and ecosystem in Ehime. So, we could learn a lot of science. This training was valuable for us.
・Lecture “About Shikoku Seiyo Geopark”(by Mr. Takahashi)
・Field trip to see fossils from the Jurassic era. (We saw fossils that are rare elsewhere in the world; one such type was “rudists,” for example “asari.”)
・Field trip to Anagami cave. (We saw three hundred Kikugashira bats.)
・Went to the Shikoku geo museum. (We touched the oldest rock in the world, Acastu Gneiss.
~Feeling~
　Unlike Matsuyama City where we live, we came to know Seiyo City and were able to rediscover the charm of Ehime Prefecture.
         
〈second day 12/14〉
　 Ehime University's Nanyo Fisheries Research Center, in collaboration with the town of Ainan, is conducting research aimed at the complete cultivation of "Ehime Suma" or sea bream.
 This session, Dr. Hidetaka Takeoka, the director of the center, gave a lecture on the bright future of the fishing industry and the "science mind". In the afternoon, we visited the laboratory, aquarium, and fishpond where students work hard day and night on their research.
 I was able to fully feel the appeal of the science of fisheries in the majestic nature of the Uwajima Sea.
　・Lecture : Current status and future prospects of fisheries in Ehime, research and human resource development at the Nansui Research Institute, scientific thinking, etc.”
(Dr. Hidetaka Takeoka, the director of the center)
・ Visit to Funakoshi Station : We visited a state-of-the-art research facility.
・Visit to Nisiura Station (Umiraiku Ainan) : We observed the ontogeny of zebrafish in real time.
　By observing the large-scale laboratory equipment and advanced research contents of the Ehime University Minamiiyo Fisheries Research Center, expectations and hopes for the future course grew, and the motivation for SS has further increased.
         

Organizer: Ehime University Environmental ESD Instructor Training Course
Joint Sponsorship: Ehime Prefectural Matsuyama Minami High School “Ehime High School Students SDGs Meeting”

[The First Meeting]
(1) All-Genders Area
(2) SDGs School Area

　In the 3rd Year of the Reiwa Era, the Ehime High School SDGs (“sustainable development goals”) meeting was held. The first and second grade students participated in this meeting. This year, it was planned/organized by Ehime University students. We discussed “what we can do” and “what we want to change” with Prof. Osamu KOBAYASHI and five university students.

　Though Minecraft is a popular video game these days, it seems that it is being introduced in elementary schools in developed countries as a tool for learning programming. Since it seems to not yet have been introduced in higher education to a large/significant degree, we were only able to experience “advanced science.” Owing to Internet security reasons, students were not permitted to use their own PCs, however they were able to experience “SDGs in Minecraft” with university students’ PCs. ■

Author’s Opinion: Although it is a little difficult to consider SDGs as a personal problem, I thought it was interesting and easy to understand, because I could think about SDGs in the context of a virtual school built in Minecraft. I think it is important not only to verbalize what I think but also to be able to visualize it in order to find ways to solve the problem. (204 Rei MATSUMOTO)
     

   On November 18th and 25th in the afternoon, a high school and university collaboration class held by teachers at Ehime University was held for the second time this year.

   First grade science and mathematics class physics course “All About Plasma Energy”, by science and engineering class Prof. Tsunehiro MAEHARA.
First grade science and mathematics class biology course “Understanding viral infection from the basics, and activities at Ehime University Proteo Science Centre”, by Centre associate Prof. Hiroki TAKAHASHI.

   Second grade science and mathematics class Medical Life Science course “The origin of diseases caused by cell disorders, the significance of high school and university collaboration and total type selection” by medical class Prof. Junya MASUMOTO.
   Second grade science and mathematics class engineering course “The story of Earth-friendly hydrogen” by class Prof. Yoshiaki ITAGAKI.■

Author’s Opinion: We have been unable to visit the university on/for this collaboration class until now. We were taught clearly about the challenges we have faced, how to solve them, and the expected outcomes on each field as research progresses based on the content of each specialty. Our science and mathematics classmates were able to get a good chance to experience the significance of the research. We would like to thank the teachers at Ehime University. We were able to improve our own research ability, and [feel] the way of life in the future. (209 Hiroto OKA)

   On November 20th, the Natural Sciences Division of the 35th Ehime Prefectural High School Comprehensive Cultural Festival was held. 18 students from class 209 participated, submitting 9 works in total. As a result, “Removal of Marine Pollution Substances by Negibouzu” (onion-head plants) won the excellence award, which is equivalent to the first place in the Chemistry category, and it will be recommended as a representative of Ehime Prefecture to the 46th National Cultural Festival to be held in Tokyo next year.

   However, including other teams of our school, during the question-and-answer session with teachers and students from other schools, I encountered a problem in how to summarise and present our research results. Despite the current situation where contests have been cancelled or held remotely due to the influence of the new coronavirus, this was the first opportunity for students to present their research to students from other schools, and they were unprecedentedly nervous, The teachers think that we can improve our research by gaining such experience and coming into contact with good presentations and works from other schools. They would like us to spend our time researching how to write a dissertation, collecting data that is still lacking, and summarising good research results.

Author’s Opinion:
 I received a lot of advice from teachers and students from other schools at this competition. From now on, I would like to make use of it to advance my own research and have more fun.(209 Yuha KITAMURA)
    

　On Sunday November 14th, we participated in this conference. 　We exchanged our opinions and presented the results of the international joint research we have been conducting since this summer. 　We seven first-year students from the chemistry and biology clubs gave our presentations and answered questions. 　Although it was our first presentation, it was a good experience for the future.

Acomment from a student: On that day,scientists and research students of the university taught us the fun of sciencethrough various experiments and observation.  I was particularly interested in theexperiment that explained how rockets are able to fly.  This was explained straightforwardly bycomparing balloons to beach balls.  Atthe lecture, I was able to learn both the fun of space engineering and thenatural English spoken by native speakers, which was a valuable experience forme. ― Sakura KUBO, Class 106
         

October 28th, 2021 

The data marketing education program that we have been working on forseven months with three companies ― FUJI, SEKI, TRUE DATA― has finally reached the final round.

On Tuesday, October 26th, our school wasvisited by four representatives of FUJI Co. Ltd., including Director ONISHIFumikazu; three representatives of SEKI Co. Ltd., including C.E.O. SEKIHirotaka; and one representative of TRUE DATA Co. Ltd., Deputy Director ofAnalytical Solutions KARASUDANI Masahiro.

   On this day, the final announcement wasgiven.  From the purchase data, we firstdefined four target groups: group 1 as “elderly housewives who buy in bulk”,group 2 as “typical housewives of average age who shop in the morning”, group 3as “customers who like new products”, and group 4 as “those with long workinghours”.

   By reading trends from this data, wesubsequently derived four product groups: group1 as “cultured red sea breamcaught fresh in the morning”, group 2 as “fresh and seasonal vegetables”, group3 as “new snack products”, and group 4 as “karaage(Japanese fried chicken),shochu (Japanese spirit) cocktails, raw vegetable salad, and delicatessen.”

   By taking these factors into consideration,we implemented measures at FUJI’s “Fujiwara” store aimed to increase theirsales.  We compared the purchase data atthe store from before and after the introduction of these measures using an“analysis tree.”

   In response to each presentation, questionswere asked by YANO Kyoko, MIYAWAKI Masami and IWAMOTO Ryo from the SalesPlanning and Marketing department of FUJI Co. Ltd.; and by KARASUDANI Masahiro,Deputy Director of Analytical Solutions of TRUE DATA Co. Ltd.

   After the presentations of all the groupswere finished, we received comments from Director ONISHI Fumikazu of FUJI Co.Ltd., from President SEKI Hirotaka of Seki Co. Ltd., and from C.E.O. YONEKURAMasayuki of TRUE DATA Co. Ltd. Selected quotes include: “This effort does notseek a single correct answer,” “The important thing is how to make use of what younoticed in the process,” “It is important to talk not based on intuitions, buton evidence and data,” “It is crucial to reflect on what to do next,” “Theknow-how of what was and was not effective accumulates as data,” “On thisprogram, I think came in contact with the way of thinking of working people,and learned from it,” and “We create the future with data and wisdom.”

   This time the students gave a wonderfulpresentation as a culmination of the program, which started in March.  We would like to thank FUJI Co. Ltd., SEKICo. Ltd. and TRUE DATA Co. Ltd. for providing us with such a valuableopportunity.  I think that the studentswill make good use of this experience to further deepen their learning atuniversity, and revitalize Ehime prefecture in various ways by playing activeroles as human resources. 

   Author’s opinion: “Although I have some regrets, I am happy to have been able to make thefinal presentation successful in this way. Furthermore, we are grateful for the opportunity when we can learn “datamarketing.”  I am sure that thisexperience will be a great help when I work on the data marketing project.”― 208 KOIKE Shogo
 
       

Reiwa Year 3, on Sunday October 24th,we discussed the experiment at data with Waipahu High School students in Hawaii(4 students), who are conducting international research on purification ofwater, for a period of one hour. Uwajima Higashi High School Students（6 students）,who have engaged in international relationwith Hawaii.  After they explained the experimentaldata from each country, a question and answer session was held.  Our High School students asked questions proactivelyabout the followings: COD value increase at the downstream in Kapakahi River inHawaii after rain, and the reason why TH value tends to increase, and so on.  This research will be summarized in a paperand exhibited in a domestic contest.  Fromnow on, we will discuss the topic again, continuing to conduct experiments forthe international contest held next year in December.

Impression:This discussion was a valuable experiencefor me.  It was the first time for me tospeak English outside of class.  So I wasvery nervous.  However, Uwajima HigashiHigh School students were smiling and friendly.  I was surprised to see that they are alsousing plants to tackle water issues.  I thoughtit was an interesting idea.  We'll do ourbest, too. ―　Kaio Matsumoto, Class 109
                 

　On Tuesday, October 19th, our school was visited by representatives of FUJI Corporation, Ms. MIYAWAKI and Mr. IWAMOTO from Sales Planning and Marketing, and of SEKI Corporation, Mr. AKAO from the Information Service Industry Promotion Office and Mr. MORIOKA from the Corporate Planning Department.
　The content of the day was “creating a presentation for the final phase.”  Building on the previous lecture “on a method of verifying effects from numerical values,” we were instructed on various topics, using the purchase data provided to determine growth rate, by comparing with prior growth rates and the growth rates of comparable stores.  Analysis was performed on the number of customers from the number of receipts, category purchase rates, and other customer data, which was summarized in the presentation.  We also examined the sales at the store where our students carried out data collection.
　Ms. MIYAWAKI and Mr. IWAMOTO advised us on any matters we did not understand or were unsure of while putting the presentation together.  We are grateful that you continued to answer some of our questions even after having exceeded the scheduled time.  The program started in March, and our next meeting will be the final one.  As a culmination of the program, we hope to give a good presentation then. 
Author’s opinion; “I really appreciate all the instructors of this program for their efforts.  I will make use of what I have learned during these months after my school life.”  207 SHIMIZU Hono 
       

　Two teams from our school were selected as finalists in the “WiDS HIROSHIMA Ideathon2021”, a collaboration between industry, government and academia; including Hiroshima Prefecture itself, Hiroshima University and related companies. 
　WiDS is an abbreviation for “Women in Data Science,”an initiative led by the Institute for Computational and Mathematical Engineering (ICME) at Staford University in the U.S., which aims to “foster human resources who will be active in the field of data science, regardless of gender.” 
　On Sunday October 17th, the WiDS HIROSHIMA Ideathon 2021 “Pre-Advice” session was held, with the attendants including 9 students from our school who will participate in the finals. 
　After showing the announcement materials and our presentation, we were advised by Ms. SAGA Yukiko, the WiDS HIROSHIMA Ambassador on various topics, including methods of showing data and how to make presentation slides. Based on this advice, we would like to further improve our presentation for the finals. 
　WiDS HIROSHIMA Ideathon 2021 can be viewed online.  Please register in advance, and we thank you for your support. 
   Student’s Opinion: “I’m glad that we were able to participate in this event because it helped make our issues much more clear. Mrs. SAGA gave us specific information on which kinds of presentation are easy to read, and what kinds of data are persuasive. I’m going to work hard for the main competition in January!”-SENBA, Class 201  
   Student’s Opinion: “The most difficult aspect of creating presentation materials was deciding on the kind of data to use to create the graphs. Instead of just arranging the quoted data, I tried to create more profound materials by combining multiple kinds of data. I would like to go forward making presentations that are clear and easy to understand.” -NISHIDA, Class 201

　They talked about cutting-edge scientific researches and technological developments that are not usually known.  We are very interested in each content of the lecture.  I felt a lot of fun to know a lot of researches and scholarship.   ( Mikawa )
       

　On Tuesday, September 14th, the 7th period, a data science lecture was held for second-year students in the general course and science and mathematics course. In collaboration with Center for Data Science, Ehime University (CDSE), we are working to improve the quality of research on issues.

    This time, two professors from Ehime University gave lectures to us.
First, Professor Naomichi FUJIUCHI, Graduate School of Agriculture in Ehime University, gave a basic knowledge of statistical processing methods when dealing with data under the theme of "Survey on the growth of plant-grown tomatoes: comparison and modeling".
    Second, Professor Yoshihiro MIYAKE, Department of Epidemiology and Preventive Medicine of Graduate School of Medicine in Ehime University, gave a lecture on the role of data science in epidemiological research and how to analyze data under the theme of "What is epidemiological research?"

    In addition to learning how to analyze in an easy-to-understand manner, I was able to learn specifically about the roles that data science plays in the world.
I will firmly use this method in future researches.
    It was an interesting lecture, in which various information based on data and research, was obtained.  And we came to know the concrete importance of data science.　(２０４class Aya Matsumoto)
