This investigation was made in 1958 to estimate the amount of damages to be done by the prevailing easterlies to the rice yield in the area at the leeward of the windbreak on the seashore near Yamoto Town, Miyagi Prefecture, as a result of the cutting-down of the forest for the purpose of enlarging the landing strip of Matsushima military air depot.The outline of the information I have obtained on the effective limits of the windbreak and the estimated distance distribution of decrease in rice crop, will be given below.(1) On the map I drew two lines (A) and (B), one on the paddy fields exposed to the breeze and the other on the paddy fields at the leeward of the shelter-belt of trees. The measuring spots were placed at every 100 meters on the lines. The comparison was made between the rice yields at the corresponding spots of each line, and the difference between them was considered being made by the shelter-belt of trees. The same comparison was made at the area on the other side of the air depot. For comparison at the measuring spots I used the average rice yield per 10 a figured out by the Yamoto Agricultural Insurance Association.(2) The effective zone of the windbreak on rice yield was found out having a radius of about 400 meters from the forest, in other words, a screen of trees gives useful shelter to about a distance of thirty times its height. This finding was in accord with the calming effect of the forest measured by the Sendai Meteorological Observatory.(3) In case when the windbreak is cut down, it can safely be guessed that between the distance of the forest and the rice yield will be formulated by the following equation (see Fig. 3):Y=0.07x+68 (σ=2.2)Therefore, after the windbreak has been destroyed, the paddy fields near the forest are supposed to show about 30 percent decrease in production as compared with the non-effective site. The decrease percentage increases with the distance—about 7 percent every 100 meters—and at a point 400 meters from the screen of trees, the rice production comes to be free from the influence of the forest.

Light Rail Transit (LRT) System and tramways based on it in urban areas have been appreciated again. This paper analyzes comparing forms of cities that have been preserving tramway and have dismantled it. Therefore, the focuses of analysis in cities are characteristics of urbanization and compactness of urban structure. It was found that in cities preserving tramways wall, environmental-destroying urbanization rates are lower than others. Above all, compactness rates of urban structure are unexpectedly high.

A runway for the operation of a fixed-wind UAV cannot be always available in practical missions and there is no handy method for landing in confined space while a catapult can be used for launch. The purpose of this paper is to develop a new vertical landing method using the flat spin. Flat spin is the motion that an aircraft rotates horizontally while it is descending vertically. In order to control its touchdown position to a desired position, it is necessary to generate centripetal force to control UAV's descent path to target direction while descending vertically. This paper shows the method to change the path during vertical descent, as well as the result of flight tests and wind tunnel tests.

A 21-year-old male was shot with a handgun in the mandible, chest, inguinal region, and upper limbs. Upon admission to the emergency room, vital signs were relatively stable.X-ray examination of the head and neck region apparently revealed that the right side of the mandible was fractured and that the bullet-shaped radiopaque object was lodged in the tongue. However, because the radiopaque object in the tongue was found intraoperatively to be a full cast crown on the mandibular firstmolar, the initial clinical impression of the route that the bullet passed through the body proved to be mistaken. The comminuted mandibular fracture was reduced and stabilized with a miniplate under general anesthesia.Five months later, after an abscess appeared in the right submandibular region, the remaining bullet fragments were surgically removed. The postoperative course was uneventful.The unique characteristics of gunshot wounds shoud be carefully considered at initial assessment.

本稿は,組織と感情との関連で問われてきた,感情労働と自己への否定的効果という疎外論モデルの再検討を通して,感情労働へと人々が動員される機制を分析するものである.まず,感情労働は三者関係で捉えられるべきものであり,クライエントも「感情労働者」として振る舞わざるをえないこと,ならびに,組織が感情を要求しつつ/拒絶するということが,感情労働を職務の魅力と感受させる機制を持つことが示される.

In this paper, we investigate whether human resource management practices can significantly enhance the work-life-balance satisfaction of workers using personnel-micro data from a Japanese medium-sized company, comprising approximately 600 employees. The dataset is of all regular employees working in one manufacturing company including in both blue-collar and white-collar occupations of three divisions: Product, Sales, and R&D. The objective of this study is to examine the heterogeneity and trends of human resource management. The results showed that there is a positive relationship between the fairness of job allocation and the work-life-balance satisfaction. It was also found that under-skilled workers in the Sales (R&D) division receive significantly lesser (higher) work-life-balance satisfaction than their correctly placed colleagues, after controlling for boss effect and other workplace characteristics.

加齢による卵巣の予備能低下が主な原因とされている難治性不妊症では,高度な生殖補助医療技術(Assisted Reproductive Technology:ART)に加えて補助的治療が必要となる.そこで我々は,血流改善効果を有する低反応レベルレーザー治療(Low reactive Level Laser Therapy:LLLT)に注目した.難治性不妊症患者337 例に対してLLLT を行い,妊娠した症例は110 例(妊娠率:32.6%)であった.漢方療法やメラトニン内服療法などの従来の補助的治療とほぼ同等の治療成績が得られ,LLLT も補助的治療の有効な手段に成り得ると考えられる.今後は従来の補助的治療と組み合わせることで,更なるART の治療成績の向上が期待される.

In many cricket species, male crickets sing a specific song to call female crickets, and Japanese people have felt their songs tasteful and one of the seasonal scenes. This study investigated the relation between the songs and human mind and considered how people feel the songs. Three different species, Homoeogryllus japonicus, Teleogryllus emma and Oecanthus indicus, were used for this study, and the specific songs were statistically analyzed. When fluctuation pattern of the songs were analyzed, a 1/f mode was often seen at the range of low frequency regions of power-spectrum, suggesting that the songs are pleasant. Then, the impressions of the songs were investigated with SD-method, and the results of factor analysis showed that the songs gave pleasantness to people. Especially, people felt comfortableness to the sound and rhythm of H. japonicus and T. emma song. We finally conclude that these songs remember people some natural scene and gives a pleasantness.

大量に発生するコンクリートがれきの処理やセメント製造時のCO2 排出の削減が課題となっている.本研究では木材を使用することで,セメントを使用せずにコンクリートがれきを硬化体として再生する方法を検討した.具体的には,コンクリートがれきと木材のそれぞれを粉砕して得られる粉体を混合してホットプレスすることで硬化体を製造し,コンクリートと木材の割合,含水率,成形温度などが硬化体の曲げ強度に与える影響を検討した.実験の結果,これらの条件を変化させた多くのケースで,一般的なコンクリートの曲げ強度を大きく上回る結果が得られた.
