浅田孝の子供に対する環境開発の手法に関する研究

Takashi Asada belonged to Kenzo Tange's laboratory and starting with Reconstruction planning of Hiroshima City (1946-47), he was the main partner when Kenzo Tange designed Hiroshima peace center (1952) as well as Kagawa prefectural Government Hall (1958). Independently, he also designed Showa Station of Antarctica (1957), managed World Design Conference (1960) etc, and had played the important role in various fields beyond architecture planning and design. In 1961, Asada established "KANKYO KAIHATSU CENTER" with the meaning "research center for environmental development and design" which is the first consultant of urban and regional city planning in Japan. "KANKYO KAIHATSU RON" (1969) which means "theory of environmental development" was the only book written by Asada. He attended to establish the theory of environmental development and carry various works out through his concept as one of pioneers in Japan however Asada's theory of Environmental Development has not been clarified specifically. In his actualized works, there are 2 projects for children: Kodomo no Kuni as national children land in Yokohama (1962-72) and the development in Goshikidai of Kagawa (1965-71). This study aims to clarify Asada's method of environmental development for children through the analysis of 2 actualized projects as a part of his method of environmental development as follow. (1) Collecting information on projects and discourse concerned with children by Asada to clarify his theory for children. (2) Analysis of reflection of Asada's theory for children in program, planning and design of Kodomo no Kuni. (3) Analysis of organization frameworks and decision-making process in Kodomo no Kuni and ascertaining his role in 10 organizations. (4) Clarify points of common and development between Kodomo no Kuni and the development in Goshikidai. Throughout the analysis, the following 5 points have become clear. 1. Asada had his theory that children should act and play voluntarily in nature environment for education planned and design as less as possible. He believe in this environment encourages them self-development. In development of Goshikidai, outdoor activities had been taken in the program of school education with cooperation of governor and superintendent of education in Kagawa Prefecture. 2. Asada played an important part in site selection for Kodomo no Kuni. And that action changed the plan of Kodomo no kuni from smaller site(36ha) to the bigger site(96ha). 3. At first, the plan of Kodomo no Kuni was programmed to focus on artificial facilities like Disneyland. Asada denied it and planned minimal facilities for children's various outdoor activities. The completed plan followed Asada's concept and program generally. 4. Asada trended to introduce master plan like the cluster pattern and distributed facilities dispersively in each zone separated along the topographic features to suppress unnecessary development on nature in planning design of each project consistently. Asada tried to reuse architectural remains in Kodomo no Kuni and planned Goshikidai including existing temples, industry or facilities for children's activities and sightseeing. 5. Asada not only did planning and design, but also suggested concerning PR, management or personal affairs in each organizations of Kodomo no Kuni. In implementation process, he organized group formed of specialists, designers and architects in different field in order to design the environment comprehensively without differentiating fields and scales. Asada used the method of environmental development in cross-sectional fields to control organization in both decision-making and design and connected several organizations to design the environment comprehensively like Kodomo no Kuni.

Problems of Thyroid Ultrasound Screening–Based on the Results of Thyroid Screening Conducted at Our Facility 25 Years Ago in Japan

Surgical cases of papillary thyroid cancer have increased in many countries recently. The main factor is that the ultrasound examination device is widely used. Improved image quality is also a factor. We present the results of thyroid cancer screening through ultrasound examinations performed 25 years ago and mention the problem of over-diagnosis in thyroid cancer screening. From 1990 to 1995, we presented the results of our ultrasound screening for thyroid cancer in Kagawa Prefecture, Japan (1 million people). The subjects were 11,189 women with no neck symptoms. They were examined using a surface ultrasonic apparatus. After detecting abnormalities, fine needle aspiration cytology was carried out. If the patient were diagnosed with cancer, a lobectomy was performed with a side neck lymph node dissection. 140 cases of thyroid cancer were detected in this screening. The histological type of all detected cancer was papillary carcinoma. The detection rate of tumors with diameters of 3mm or more was 3.6%; 10mm or more was 0.88%; 15mm in the tumor diameter was 0.27%. Lymph node metastasis was observed 33% in tumors sized 3∼9mm, 56% in tumors sized 10∼14mm, and 94% in tumors sized 15mm or more.If we enforce the thyroid cancer screening by ultrasound examination, the detection of thyroid cancer in 3mm or more is 3600 per 100,000 women, the detection of 10mm or more is 880 per 100,000 women. But the annual number of suffering from thyroid cancer in Japan is approximately only 7 per 100,000 women. The deviation between the two is very large. We inferred that small papillary thyroid cancer is passed without problems accompanied by lymph node metastasis. For thyroid cancer screening using ultrasound, the problem of over-diagnosis is raised. The detection of thyroid cancer through aggressive use of ultrasound is not recommended. Surgical indications of subclinical thyroid cancer should be determined with restraint. Asymptomatic small papillary carcinoma should be regarded as innocuous.

A Scale of Parental Anxiety about Pediatric Emergency Medical Care Services of Japan: Development, Reliability, Validity, Generalizability and Usefulness

Aim: The purpose of this study was to develop a scale, “parental anxiety about pediatric emergency medical care services” (PAPEMCS), and to evaluate its psychometric properties. Methods: Participants were 14,510 parents with children 6 years old or younger in Kagawa Prefecture. Using each half of the participants, exploratory factor analysis was performed to generate items and factors for the PAPEMCS, and confirmatory factor analysis (CFA) was used to establish the construct validity. The generalizability of the PAPEMCS was evaluated by congruence tests and multigroup CFA. The usefulness of the PAPEMCS was established by the relationship between the PAPEMCS and non-urgent usage of pediatric emergency medical care services (PEMCS). Results: The PAPEMCS compromised 4 factors: “anxiety about quality of PEMCS”, “anxiety about PEMCS system”, “anxiety about public support”, and “anxiety about private support”. All reliability estimates (polychoric ordinal alpha coefficients, item-rest correlations), the item discrimination, 5 fit indices for CFA, the convergent validity (indicator reliabilities, composite reliabilities, average variance extracteds), and the discriminant validity fulfilled the acceptability thresholds. All generalizability estimates fulfilled the predetermined levels of acceptability (Tucker’s congruence coefficients, congruence tests, strict factorial invariance). The usefulness of the PAPEMCS was established by the higher scores of the PAPEMCS being related to non-urgent usage of PEMCS. Conclusions: The PAPEMCS demonstrated satisfactory reliability, validity, generalizability and usefulness. The PAPEMCS is useful to quantify the contents and extent of parental anxiety about PEMCS, and to clarify the mechanisms of non-urgent PEMCS usage.

冬季タマネギにおけるネギアザミウマ（アザミウマ目：アザミウマ科）の発生動態

Occurrence of the onion thrips, Thrips tabaci Lindeman, was examined from late December to late May at onion fields with three different cropping types, early, middle, and late seasons, in Kagawa Prefecture, western Japan. In the early season onions, survival of adults, larvae and newly hatched larvae of T. tabaci was observed on onion plants during winter and their occurrence was increased from April. In the middle season onions, T. tabaci of all developmental stages were found from late April. In the late season onions, newly hatched larvae increased from early March in the field where T. tabaci adults had occurred. On the other hand, no such increase of newly hatched larvae was observed in the field where fewer adults had existed. Oviposition of adults on onion seedlings was also examined in the laboratory and field conditions in March. The newly hatched larvae from onion seedlings were found at 10°C and 20°C in the laboratory and in the field.

農業経営組織における雇用管理・人材育成の動向に関する考察

Based on a questionnaire survey conducted in Kagawa Prefecture, this study empirically explores the tendencies of employment management and human resource development in farm organizations. The study shows that introducing permanent workers in their farms, farm managers in Kagawa Prefecture tend to develop a system of command and supervision of workers. With increasing workers, they begin relegating an employee to the charge of production management or supervision of other workers. It is shown that farm managers reaching such managerial levels tend to expand their farm sizes rapidly, and often induce employees to enhance their ability of operational judgment and understand their farming goals or plans. It is also shown that these managers frequently use economic incentives such as salary or position upgrades. With the help of organizational economics theory, this study presents economic explanations on the abovementioned tendencies.

香川県における良食味水稲品種ヒノヒカリの不耕起乾田直播栽培に関する生育，収量および食味

2013年と2015年に香川県高松市の農家水田において水稲品種ヒノヒカリを供試し，不耕起乾田直播栽培が生育，収量，品質，食味に及ぼす影響を調査した．不耕起乾田直播栽培区（直播区）の収量は，移植栽培区（移植区）に比べて2015年は6％の減収にとどまったが，2013年は37％減収した．2013年の減収原因は播種期前後の降雨不足に伴う苗立ち抑制による穂数の減少にあった．外観品質には処理区間に有意差は認められなかった．食味に関しては，直播区産米は移植区産米よりも最高粘度とブレークダウンが大きく，味が良く，粘りが強くて軟らかいために総合評価が向上する傾向がみられた．

香川県指定文化財猪熊家住宅母屋の改造履歴に関する研究

This study aims to trace the remodeling history of the Inokuma house, cultural property designated by Kagawa Prefecture. The Inokuma house has been considered a crucial remains that was built in 1664 and maintain the plan and design at the times. We searched for the remodeling evidences and historical papers indicating the remodeling history. The site plan that was drawn in the Meiwa Period (1764-1771) made it possible to restore the house to its original plan at the time, and 2 old drawings about the massive remodeling in the Meiji Period (1868-1912) were found.

Prevention of Lifestyle-related Diseases by Utilization of Newly Developed Health Record Booklet "My Karte" in Mitoyo and Kanonji Areas.

In the Mitoyo and Kanonji areas, Kagawa Prefecture, Japan, we have newly developed a simple health record booklet for parents with children called "My Karte", which is an enlarged edition of the maternal and child health handbook. Our municipality borough gives this booklet together with the maternal and child handbook to all pregnant women without exception. In this booklet, care personnel or child by themselves write down the health condition and body development of the child, including medical examination records and vaccinations. From an overview of this simple record, healthcare practitioners, caretakers or school nurses can immediately grasp the child's body condition, for example, whether the child is overweight or underweight, and various health problems early and precisely. In addition, the child and care personnel can evaluate the health condition of the child through self-assessment. We hope that the self-assessment will promote health during the child's life. Moreover we are planning to collect and analyze the data from the distributed My Karte. The analyzed results will be released to the public, which will promote health consciousness in this area and give healthcare professionals basic and important data useful for daily medical practice.

人工地盤上の空間構成とコミュニティ形成に関する研究

Sakaide Artificial Ground in Sakaide, Kagawa prefecture (built 1963-1978) is a known example of the combined applications of Modernism and Metabolism in post-war Japanese Architecture. It was developed as a high-density complex for commercial use and public housing. The ground floor is for retail spaces, theaters, restaurants and parking and the second level artificial ground was built for public housing. At present, the structures are partially deteriorating, outdated, and are used by a community composed of aging residents. The pedestrian traffic and circulation within the area is affected by the lack of elevators, narrow paths, and steep stairs. While Sakaide Artificial Ground was a frontier development during the post-war era, its design is no longer relevant with its present use and is expected to hugely affect the living situation of the residents. For example, on the second-level artificial ground, the privacy of the residents are noticeably different from public housings that are built on natural ground. Residents in Sakaide Artificial Ground use the public area like they own the open spaces privately. This paper aims to clarify the influence of the interaction of residents on the community formation of Sakaide Artificial Ground, focusing on how to use the public area of public housing. The measures devised to obtain data are: (1) surveys to investigate the occupation and utilization of the public areas that are affected by the residents' perception of personal space, (2) the time sampling procedure to record behaviors of residents in relation to time-patterns, (3) behavior mapping to investigate the nature of activity, and (4) the last one, interviews, to investigate the perception of the residents. In conclusion, results of the study show positive actions by residents' autonomy in the use the public area of public housing. For instance, residents voluntarily encouraged the use of the public area, and this activity contributes to the formation of the community of Sakaide Artificial Ground.

豊島廃棄物等処理事業における処分地管理手法の高度化に関する検討

This report shows the development of a management method of Teshima waste disposal project using GPSbased 3D modeling method. Teshima waste disposal project has been conducted since 2003 as a solution of the illegal industrial waste dumping occurred in Teshima-island, Kagawa Prefecture. To prevent illegal dumping and to accumulate data of this project, we took a survey of the disposal area 4 times a year and made the 3D model of the area. By comparing the 3D model change in time course, we can show stakeholders how the project has advanced. And by surveying the area changed between the two 3D models, we can calculate the volume of disposed garbage. So, we call this system a “Co-creation system”. Therefore, we compared the cost and accuracy of GPS surveying, Light wave surveying, and Laser surveying. With this system we promoted information sharing between stakeholders.

香川県産飼料用オリーブ葉のポリフェノール含量に及ぼす保存方法の影響

養殖魚の飼料用に使われている香川県産オリーブ葉のPP含量と，オリーブ生葉中および葉粉末中でのPPの安定性を調べた．その結果，香川県の主要3品種のオリーブ生葉のPP含量は，7.3∼8.2g-GAE/100g-DWと，中国四川省産やイタリアパルマ産よりも高く，品種間での含量の差は小さい傾向であった．オリーブ葉の主要PPであるOLP含量は，剪定してから乾燥処理を行うまでの保存状態や保存時間によって著しく変動することがわかった．すなわち，屋外温室や冷凍室に保存するとOLP量は減少してしまうが，室内に保存し2週間以内に乾燥することで高いOLP含量を保持できることがわかった．また，乾燥·粉末化したものは，密封·暗所で常温保存すると1年間はOLPを安定的に保つことができることがわかった．
