The purpose of this study is to clarify the changes of water usage and consciousness of water-saving in Fukuoka-city by comparing the past investigation results in 1989 with those in 1999 passed 20 years from the big water shortage, and to collect the basic data for the planning of effective water usage in houses. In this paper, we clarified the factors of distinction between the results of investigation in 1989 and those in 1999 for detached houses and apartment houses respectively. And we analyzed quantitatively the changes of the factors affecting the volume of water consumption and so on.

夏期の都市熱環境における水面・緑地の効果に関し、実測調査を主とした総合的な研究を行い、以下のような成果を得た。1.海風の冷却効果に関して、風向・風速と気温の3地点同時の長期観測を実施した。陸風から海風への変化により、気温上昇の緩和あるいは気温の低下が認められ、海岸からの距離によって異なるが、平均的に3℃程度に達する。2.河川上と街路上における熱環境の比較実測を行った。河川は風の通り道としての役割を果しており、その水面温度も舗道面温度などに比較して最大30℃程度低い。その結果、海風時の河川上の気温は街路上のそれに比較して低く、その気温差は海岸からの距離により異なるが、最大4℃に達する。3.満水時と排水時における大きな池とその周辺の熱環境の分布を実測した。池の内部と周囲には低温域が形成されており、その外周200〜400mまでの市街に対し0.5℃程度の気温低下をもたらしている。その冷却効果は池の風上側よりは風下側により広く及んでいる。4.公園緑地内外の熱環境の分布を実測した。公園緑地内はその周辺市街に比べて最大3.5℃低温である。また公園緑地内の大小に依らず、緑被率、緑葉率に対する形態係数が大きくなれば、そこでの気温は低下する傾向にある。5.地表面の粗度による風速垂直分布および地表面温度分布を境界条件として、LESとk-ε2方程式モデルを用いて2次元の市街地風の数値シミュレ-ションを行い、市街地の熱環境を数値シミュレ-ションにより予測できる可能性を示した。6.建物の形状や配置を考慮した地表面熱収支の一次元モデルを作成し、都市の大気境界層に関する数値シミュレ-ションを行い、接地層の気温の垂直分布について実測値とよく一致する結果を得た。建物高さ、人工廃熱、水面・緑地の面積率などに関してパラメ-タ解析を行い、都市の熱環境の定量的な予測を行った。

The purpose of this study is to collect the basic data for planning effective using systems of water resources in region. We research and analyse the people's water uses and opinions in the dwelling houses, which are along the 9 channels in the river basins of the Chigusa, the Maruyama, the Asahi, the Chikugo and the Yabe. We describe the frequencies of water uses in each purpose of using water and the opinions for saving water. We analyse the relation between the character of family and the water uses by the Quantity theory cluster III, and we clarify the difference so that the urban people pay attention to water uses more than the rural people. In three cases using tap, well and channel waters, we analyse the water uses, the opinion of water uses, the evaluation of water quality and the factors of water using pattern. In these analyses, we clarify that the tap waters are lower than the well waters in the evaluations of "Smell", "Temperature" and "Taste", and we describe that the people using well and channel waters have the requirement to keep the presented water use system, and that the degree of the requirement is affected by water quality. Considering the relation between the water quality and the evaluation of water and the relation between the water quality and the water use, we clarify that the relation between water index S (COD, turbidity) and the evaluation of water R makes an approximation with an equation R=kln (S/So), (Now, k and So : constants), and that there are similar relations between these indexes and the ways of water use.

Passive utilization of natural energy is one of the most reasonable way to improve the urban thermal environment in the warm season. The sea-land breeze is an appropriate energy source for this purpose. Statistical method to extract and express the sea-land breeze component from the wind data and the relation between that and the solar radiation data are described in this paper. The AMeDAS and the SDP data, from 1980 to 1984, in 12 cities which are scattered in the whole country are used. The analysis period, which means the warm season, is fixed on condition that the 7-day moving average of daily mean air temperature is above 20℃. The sea-land breeze axis is decided from the wind rose in the analysis period. The sea-land breeze component means the wind vector component of this axis. Sea breeze hours and land breeze hours are fixed by the average sea-land breeze component at each time. The characteristics of the wind direction and speed in the sea and the land breeze hours correspond to the general nature of the sea-land breeze. The sea-land breeze intensity is defined as the difference between the average sea-land breeze component in the sea breeze hours and that in the land breeze hours. The sea-land breeze stability is defined as the ratio of the sea-land breeze intensity to the sum of the average scalar speed in these hours. The relation between the solar radiation and the sea-land breeze intensity or the sea-land breeze stability is examined.

Toughness of ceramic-matrix composites can be optimized through coatings the reinforcing fibers. Chemical vapor deposition (CVD) process is a key technology for fiber coatings. The mechanical properties of continuous silicon carbide fibers (Hi-Nicalon) have been studied as a function of the thickness of the pyrolytic boron nitride (P-BN) coating by CVD process. The compressive residual stress at the P-BN coating layer decreases slightly with increasing the coating thickness. It is considered that, with including the residual stress effect, cracking of the P-BN coating layer occurs first in a monotonic tensile fracture test. In addition no degradation of the silicon carbide-fiber in ultimate tensile strength is observed regardless of the P-BN coating thickness.

Simultaneous observations of the profiles of wind velocity and air temperature are conducted at three points in an urban area with a large pond by the kytoons. From the results of observations, convective heat flux from the ground surface to air is calculated by the traverse-method. Heat flux from the pond is negative, that is, cooling. The relation between convective heat transfer coefficient and wind velocity is obtained in extensive built-up areas. Thermal environment is observed, formed at the height of 1 meter from the ground surface in the built-up area and the large pond. New standard effective temperature of the ASHRAE, SET, is calculated as the over all thermal index at the both sites. The effects of a shade tree and wisteria trellis on thermal environment are discussed.

In this study, the river environment was chosen as the subject to consider comfortable water enviornment in region. And we have the aim to clarify the relation between the properties of river environment and people's opinions. This paper which is analysed the evaluation of living environment on the basis of questionnaire executed to the regional dwellers is the first installment of this study. The contents are as follows : 1) The Nagara, the Chikugo and the Shimanto basins were chosen as the subject to the study. We showed the properties of the three rivers and regional indexs of 9 municipalities in the upper, the middle and the lower reaches. 2) We showed the people's opinions in each region with 45 items for each evaluation of components of living environment. 3) Selecting 6 factors by the factor analysis with 45 items, we clarified the trends of evaluation with the average factor scores in each region. 4) Using 5 items for comprehensive evaluation of living environment, we showed the results of the people's opinions in each region. And we analysed the relation between comprehensive and each evaluation, using the Quantity theory cluster II and III. 5) We analysed the relation between comprehensive evaluation of living environment and properties of answerers of questionnaire, using the Quantity theory cluster III. 6) Using the average factor scores and the average scores of comprehensive evaluation in each region, we showed the correlation matrix on the 6 factors and 5 items above mentioned. Furthermore, we showed the relation between the average factor scores and the selected regional indexes.

We considered the structure of the evaluation of river environment by the people's opinions and sense based on the questionnaires executed in 9 municipalities on the basins of the Nagara, the Chikugo and the Shimanto, and mainly analysed the conservation of river environment and the accessibility to river. Now, the Part 1 on this study analysed the evaluation of living environment in the same regions. The contents of this paper are as follows. 1) We showed the properties of river environment in the 9 regions of the upper reaches, the middle reaches and the lower reaches. 2) We analysed the people's behaviours of recreation in and around the rivers. 3) As to the conservation of river environment and the accessibility to river, we analysed the people's evaluation concerning the nature of river, landscape, artificiality and playing area with water. 4) Using the factor analysis, we selected 3 and 2 common factors from the results of the people's evaluation on the conservation and the accessibility. And we evaluated the regions with the average factor scores in each factor. 5) Using 3 items for comprehensive evaluation of river enviornment, we showed the results of the people's opinions in each region. And we analysed the relation between the comprehensive, conservative evaluation and the people's properties, using the Quantity Theory Cluster III. 6) We clarified the river images by the Semantic Differential Technique using the 30 pairs of adjectives. Using the factor analysis, we selected 4 common factors from these results, and evaluated the regions with the average factor scores in each factor. 7) As to the above mentioned contents on each evaluation, we showed the correlation matrix, and showed the relation between the scores of evaluation and the selected indexes of river environment.
