CO2 included in exhaled breath is often used as a tracer gas when estimation of ventilation aspect in buildings with occupants is performed. In Japan, CO2 production rate written in JIS A 14061974, which revised in 1974, has been referred for the estimation. The CO2 production rate calculation formula given by ASTM D6245-12 can be referred also, however, the formula is based on westerner adult data. Hence, based on Japanese subjects' exhaled breath data obtained by using Douglas bag method with approximately total 170 points, equations for recent Japanese CO2 production rate are developed in this study. Moreover, an equation, whose variables are occupants' height & weight, gender, age and Met, is used for estimating ventilation aspects in single zone with occupants aiming at accuracy testing. Firstly, a simple equation (9) is derived with regression analysis using 23 subjects and 3 testing activities data. The equation requires AD (Japanese body surface area given by equation (6)) Met and CG (coefficient of gender as male: 1 and female: 0). Secondly, aiming at expanding the targets, equation (9) is transformed and verified by using additional testing whose conditions are shown in Table7 and 8. The obtained 20s males' exhaled breath data is used to derive the equation (10) whose coefficient of deamination is larger than the equation (9) shown in Fig. 4. Then, the equation (10) is added a variable Ca (coefficient of age given by table9) and is transformed into the equation (11) whose coefficient of deamination is larger than the equation (9) shown in Fig. 5. Also, the equation (10) is added a variable Cg (coefficient of gender male: 1.0 and female: 0.73 determined by Table9) and is transformed into equation (12) whose coefficient of deamination is larger than the equation (9) shown in Fig. 6. As a result, the equation (13) is derived and its coefficient of deamination is larger than the equation (9) shown in Fig. 7. With substituting CO2 production rate given by the equation (13), ASTM and JIS, into the equation (14), calculated CO2 concentration are compared to the measured value obtained in single zones with the conditions shown in Table11 with employing testing instruments shown in Table10. The experimental results are shown in Fig. 10, 11, 12, 13 and 14. From the experimental results, calculated CO2 concentration of present work shows the closest to the measured value compared with the other standards’ value. Therefore, these results can allow estimating more correct ventilation aspects with Japanese occupants.

Experiments and questionnaires were conducted at an elementary school to determine the effect of environment monitoring system on ventilation behavior. The LED lamp display according to the carbon dioxide concentration served as a criterion for decision-making on ventilation behavior, and the percentage of carbon dioxide concentrations exceeding the standard (1,000 ppm) decreased for many classrooms. Alternatively, in some classrooms, excessive ventilation was fixed, and the thermal environment was also improved. Moreover, the children’s involvement in opening windows for ventilation increased.

Background: The use of big data/real-world data (BD/RWD) is expected to be a new option for evidence generation in drug development. Pharmaceutical companies are considered to be a group of key drivers to promote widespread use of BD/RWD in Japan. However, little is reported about the current status of the use of BD/RWD for drug development in Japan.Objective: This study was conducted to reveal the current usage of BD/RWD by pharmaceutical companies in Japan and their current organization structure, with the aim to gain insight on the challenges and future perspective of BD/RWD in Japan.Methods: A questionnaire survey was conducted on 66 pharmaceutical companies affiliated with Japan Pharmaceutical Manufacturers Association from 16 to 31 October 2018. The survey consisted of two parts: Questionnaire 1 investigated the current usage of BD/RWD in drug development in Japan, and Questionnaire 2 investigated the current organization structure.Results: Of 52 companies that responded to Questionnaire 1, 30 companies (57.7%) were currently using BD/RWD for drug development in Japan for various purposes, 29 of which (96.7%) planned to continue using BD/RWD. Of 28 companies that responded to Questionnaire 2 and currently using BD/RWD, 9 companies (32.1%) had established divisions or organizations for internal management of BD/RWD, and 14 companies (50.0%) had standard operation procedures or guidance for handling legal and regulatory aspects associated with the use of BD/RWD for drug development in Japan.Conclusion: BD/RWD is currently used for various purposes in drug development in Japan. However, the proportion of companies currently using BD/RWD for drug development is limited to approximately 50%. Proactive involvement of pharmaceutical companies toward the use of BD/RWD for drug development in Japan together with further industry-government-academia harmonization for environment improvement are awaited.

日本農業は高齢化が進み,次世代を担う人材の確保・育成が重要な課題となっている.農学系学校はその入り口となる重要なものであり,より多くの若者に農学・農業の面白さや魅力を伝える必要がある.また現在日本農業はTPP交渉も含めて大きな転換期を迎えている.一方,近年国内外でアニメ,コミック,キャラクターを中心とする日本型サブカルチャーが注目されている.現在の国内における日本型サブカルチャー利用・効果をまとめると,1.実在の場所の聖地化,2.キャラクターを用いた商品パッケージによる新購買層の獲得,3.ご当地キャラクターによる広報効果,4.農業・農学校を舞台としたコミックなどによる農学・農業学校の人気・関心度の向上が挙げられる.但し,失敗例も多く,また成功が一過性のものでは長期的に活用できない.我々は調査結果を踏まえ,日本型サブカルチャー戦略の長期的成功要素の分析・考察を行って,これを踏まえて独自のアイデアとして“やおわらし”を考案・設計し,農学と農業の両面からその活用と活性化を検討した.“やおわらし”とは,「八百万の神の童子(わらし)」から作ったオリジナルの造語・概念である.具体的にこの“やおわらし”の提案,“やおわらし”活動・成果の現状の報告を本論文で行った.農学・農業両面における活用について実施しており,特にアンケート結果から現状でも評価が高く,今後の期待の声も大きかったので報告する.
