Collaborative Exploration and Collection of Plant Genetic Resources in Cambodia November 2015

This mission was conducted in northeastern Cambodia from the 8th to the 26th of November, 2015. In this region, there are many small villages of minorities, such as Phnong and Charai. In this survey, 28 genetic resources were collected, including 19 sorghum (Sorghum bicolor (L.) Moench) accessions, three erianthus (Erianthus procerus (Roxb.) Raizada) accessions, three foxtail millet (Setaria italica (L.) P. Beauv) accessions, one maize (Zea mays L.) accession, one rice (Oryza sativa L.) accession, and one sugarcane (Saccharum officinarum L.) accession.本研究報告は，独立行政法人農業生物資源研究所（生物研）とカンボジア農業開発研究所(CARDI)との間で2011年に締結した共同研究に係る覚え書き(LOA)および2014 年に締結した共同研究契約書(JRA)に基づき，2015年11月8日から26日にかけ，カンボジア北東部で行われた植物遺伝資源の探索・収集に関するものである．生物研とCARDIとの間のJRAについては，2016年4月より農業・食品産業技術総合研究機構に引き継がれている．本探索では，カンボジア北東部の少数民族の村を対象に，ソルガムをはじめとする雑穀類の探索を行った．その結果，ソルガム19点，エリアンサス3点，アワ3点，トウモロコシ，イネ，サトウキビそれぞれ1点，合計28点の植物遺伝資源を収集した

〔報告〕水・塩水で被災した資料の殺菌燻蒸の注意点：資料中の水分・塩分による副生成物の生成量の調査結果について

In disaster response of water-soaked objects,microbial contamination by bacteria and fungi is a serious problem, especially with objects that are left for a long time before recovery. Early response is the best way for the rescue of affected objects,but in the severe tsunami damage over extremely vast areas affected by the Great East Japan Earthquake in March 2011,many paper-based objects including paintings had been left for a month or occasionally for months before they were rescued. In some cases, there was much fungal damage on such objects, although, as a whole, seawater-soaked paper objects seemed to have less fungal damage than those soaked in fresh (rain or river)water. But there were cases in which severe fungal infestation was seen on paintings that had been left for months. As such objects were occasionally contaminated by wastes, treatments with germicides (which also have fungicidal effects) such as EO (ethylene oxide) or PO (propylene oxide)were considered. However, it was expected that such fumigants might react with water or chloride which is included in seawater to generate highly toxic ethylene chlorohydrin (ECH) or glycols which can attract water. Therefore the risk of generation of such chemical residues in seawater-soaked paper objects and books was investigated, partly with those actually affected by tsunami in Iwate prefecture. Some samples were dried before fumigation while others were kept wet.Consequently, ethylene chlorohydrin (ECH)and propylene chlorohydrin (PCH)were under detection level in most of the dried paper samples. But 20-50ppm of ECH was detected in books which were EO-fumigated in wet condition, and 10-20ppm of PCH was detected after POfumigation in wet condition. About 40-70ppm of glycols (ethylene glycol (EG)or propylene glycol (PG))were detected even in samples fumigated in dried condition, and much more glycols (100-400ppm of EG or 250-600ppm of PG)were detected in books fumigated in wet condition. As a whole,generation of chlorohydrin and glycols was less in samples fumigated in dried condition and the residual levels of the chemicals did not seem to be highly risky compared to the recommended residual limits set by FDA, US (1978). Therefore, it is recommended to fumigate objects in well-dried condition if such sterilization is necessary

「授業力」の向上を目指した大学生による学習支援活動： 厚田中学校における家庭科の授業を視点として

本稿では、2014年度に石狩市立厚田中学校で実施された藤女子大学学生による学習支援活動を振り返る。今回は、特に本学三年生が実施した家庭科授業での支援に焦点を当てて、授業者本人、中学校での指導教員、後輩学生の「振り返り」を掲載し、次年度の活動の参考としたい。また、この場をお借りして、本稿で報告する学習支援活動を支えてくださっている石狩市教育委員会および厚田中学校の皆さんには御礼申し上げたい。This paper aims to report on the learning support activities provided by undergraduatestudents of Fuji Women’s University. Especially this time we plan to reflect on classlessons of Home Economics taught by our third grade student. This feedback wouldgive us a chance to make clear the meaning of our learning support activities for bothof university and junior high school

Collaborative Exploration and Collection of Plant Genetic Resources in Laos, October 2015

During the Plant Genetic Resources in Asia project, the National Institute of Agrobiological Sciences of Japan and National Agriculture and Forestry Research Institute of Laos conducted a collaborative survey for plant genetic resources in Luang Prabang province in Laos under the Joint Research Agreement. Sorghum (Sorghum bicolor (L.) Moench) was the main target of the survey; however, some vegetables were also collected. A total of 12 samples collected, including nine sorghum (Sorghum bicolor ) samples, two bunching onion (Allium fistulosum L.) samples, and one chili pepper (Capsicum chinense Jacq.) sample.本研究報告は，農林水産省委託事業「海外植物遺伝資源の収集・提供強化」（PGRAsia プロジェクト）の研究の一環として，2015年10月22日から10月26日にかけ行われたラオスにおける海外植物遺伝資源の探索・収集に関するものである．本探索では，ラオスのルアンプラバン市周辺の少数民族の村を対象に，ソルガムを主目的とする探索を行った．その結果，ソルガム9点，ネギ2点，トウガラシ1点，合計12点の植物遺伝資源を収集した

〔報告〕プレハブ式高気密高断熱収蔵庫におけるアセトアルデヒドの放散挙動の把握と換気量による低減

The long-term measurement of air quality temperature and humidity and the prediction of air concentrations by numerical analysis were carried out to construct a favorable conservation environment for cultural properties in a highly airtight prefabricated storage where the air concentration of acetaldehyde exceeds the health guidelines (48 μg/m3). Monthly measurements of air quality showed high correlation between the acetaldehyde concentration and temperature. The apparent volumetric emission rate considering temprature dependence was identified from the measured values of acetaldehyde concentrations, and the prediction of annual change of acetaldehyde concentrations was conducted to estimate the effects of ventilation. The calculated results show that the acetaldehyde concentrations exceeded the guideline values from May to mid-November only with passive ventilation, indicating that active ventilation is necessary during this period. The numerical analysis showed that the acetaldehyde concentration recovered to the same values as without ventilation in less than half a day after the total heat exchanger was stopped due to the fast emission rate in summer. In summary, it was shown that characterizing problematic chemicals and understanding their emission behavior can be used to propose appropriate ventilation methods

Collaborative Exploration for Millets Genetic Resources in Laos, October, 2014

Since 2006, the National Institute of Agrobiological Sciences (NIAS), Japan, has been collaborating on the surveying and exploring on the Plant Genetic Resources (PGR) under the Memorandum of Agreement (MOA) and Memorandum of Understanding (MOU) with the National Agriculture and Forestry Research Institute (NAFRI) of the Lao People\u27s Democratic Republic (Lao P.D.R., Laos). The KAKEN mission was conducted from 16th Oct. to 1st Nov. 2014. In this mission, seeds of 19 samples of Sorghum bicolor , 5 samples of Zea mays , 4 samples of Setaria italica and one sample of Eleusine coracana were acquired. The collecting sites were Xiengkhuang and Houaphanh provinces. Topographically, those regions are located within the ranges of latitude: 19°-21°, longitude: 102°-105° and altitude: 269-1,393 m above the sea level. These seed samples will be multiplied in the field of the Agriculture Research Center (ARC) ,Genebank, Laos to study their growth characteristics to share genetic resources between Laos and Japan.独立行政法人農業生物資源研究所遺伝資源センター(NIAS)（現国立研究開発法人農業生物資源研究所）とラオス農林省（MAF）の国立農林業研究所（NAFRI）との間で締結した共同研究協定（MOA, MOU）に基づいて2006年からラオスで遺伝資源調査・収集が行われてきた．本報告は2014年の文部科学省科学研究費助成事業　基盤研究(A)25257416 辺境少数民族地帯での植物利用及び伝統知の遺存と地域発展活動や国際経済の影響評価（研究代表：渡邉和男・筑波大学）の一環として実施した．今回の調査・収集は10月16日から11月1日の期間，ラオス北東部のシエンクアン県とフアパン県で行った．これらの地域は緯度19°から21°，経度102°から105°にあり，標高は269から1393 ｍであった．収集したのはソルガム（19点），アワ(4点) シコクビエ（1点）およびトウモロコシ(5点)であった．これらのサンプルはラオスの農業研究センター（ARC）で栽培して種子増殖を行ったうえ，日本とラオスとの共同研究による特性調査に供試される予定である
