大規模災害の復旧現場では，担当者たちは不測の事態や制度面での不適合などに遭遇したとき現実的な手段・手続きなどの工夫によって知恵（＝現場知）を創出・選択して迅速・適切に対応している。現場知は復旧業務の中で消費されて忘れられているが，これらの記録・継承は今後の大規模災害時の事態の予測や対応のヒントとなり，混乱を抑え，適切な業務遂行に役立つと考えられる。筆者らは現場担当者を対象として東日本大震災の被災地区で現場知の調査を進めているが，予想以上に困難が多い。今後の災害復旧においても現場知の収集・蓄積が農業農村整備分野の経験値を高める上で求められるため，本報では筆者らの取組みと効果的な収集を進める上での課題について述べる。

Ionic liquids have various physical and chemical features suitable for lubricant. Since ionic liquid consists of large organic cation and anion, it is expected that friction coefficient of the ionic liquid thin film is controlled by an electric field by changing of the orientation of the cation and the anion. In this study, we evaluated friction force of a thin film of a reactive-type ionic liquid coated on a SiO₂/Si substrate with a conductive probe. The friction force of the substrate coated with the ionic liquid was measured while applying a voltage between the probe and the substrate. In the both coated and uncoated substrates, the friction force increased with increase in the magnitude of the voltage. When positive and zero voltages were applied alternately to the substrate, the friction force charged corresponding to the voltage.

This report is to try to study the proper placement of the exit for escape within architecture, by conducting experiments of man's probing actions for exist by means of mazes, and measuring and analizing time required to find exits. As well as in the previous report (No.1), experiments were conducted by putting on view-obstructing hats to restrict the visibility range solely downwards, so as to simplify visibility conditions. As a result, the following were clarified; (1) The distribution of time required to find the exit showed exponential distribution; and the average time required to find the exit that was farthest from the starting point became longer in proportion to the exponent of the number of crossings between the starting point and the exit, which is expressed in formula (1). (2) In the case where the maze was ahead of the starting point, the tendency was observed that the exit which faced in the same direction as the advancing way from the starting point was easier to find, and the one which faced in the opposite direction was more difficult to find. (3) There was little significant difference in time required to find the exit btween the marked maze, which had differently-coloured papers respectively at the foot of each crossing and each dead end, and the unmarked maze, which had no papers.

Many marine organisms attach to the hull and propeller surface of anchored ships. This attachment of marine organisms increases the frictional resistance of the propeller, and lowers its rotational frequency. Although anti-fouling paints for the hull prevent the attachment of fouling organisms, they contain poisonous compounds such as organic tin and cuprous oxides.
Since marine organisms cannot attach to the propeller during voyage, safe, easy and effective method to prevent attachement in anchored ships is desirable. To date, some propeller-coating paints without the poisonous compounds have been examined and developed. However, the paints have not yet been holding perfectly. In our preliminary experiment, we observed that the marine organisms were seen attached everywhere on the test plate except the scratching part. The electrolytic current, therefore, is feasible to prevent the attachment of marine organisms to the propeller. The electric technique does not pollute the marine environment, unlike the anti-fouling paints. This techique may be useful not only to ships but also to many other structures in the ocean, such as buoys, pontoon bridges and rigs.

いくらの品質を客観的に評価するための方法を確立するために,破断強度測定といくら卵膜の構成タンパク質量を調べた.
(1) いくら製品の等級は卵の成熟度で分けられている.その等級が低下するに従って,破断強度が上昇した.また卵膜成分である47kDa成分の減少とSDS溶液への膜成分の可溶化率が低下した.
(2) 原料卵を5∼25°Cで貯蔵すると,貯蔵温度が高いほど,時間の経過とともに47kDa成分の減少とSDS溶液への膜成分の可溶化率が低下していた.塩漬卵でも塩漬後貯蔵中に同様の変化が起こっていた.
(3) 塩漬後貯蔵中に47kDa成分の減少とSDS溶液への膜成分の可溶化率の低下が起こっていた.
(4) 以上の結果から,いくら品質の評価には卵膜の可溶化後の遠沈法やSDS電気泳動による分析が有効であることが分かった.

In this study, we developed four tests to estimate the ability to discriminate the design style of MUJI, which is a well-known retail brand. These tests are designed to measure a participant's ability to discriminate unknown designs by using prior knowledge of the design style. There were four steps used to develop the tests. First, one hundred and one items were developed. Second, a survey with three hundred and seven participants was conducted to examine effectiveness of the items. Third, after conducting an item analysis and verification of unidimensionality, seventy-three items were excluded. Next, an item response theory analysis was performed to the remaining twenty-eight items and their parameters of slope (discrimination) and location (difficulty) were calculated. As a result, we constructed four tests. The first two tests have similar characteristics and performances. The other two tests were for participants that had high or low ability using the twenty-eight items.
