    In this research, we carried out psychological scale measurements of "ease of hearing" in reverberant sound fields with differing echo-diagram response properties, such as changes in the reverberation time and the presence of discreet echoes in the reverberation attenuation process, as well as STI measurements and tri-syllable articulation tests varying speech rates between four patterns and conducted comparative examinations of the effect of echoes and reverberation on speech intelligibility from the correspondence relationships of the outcome of these tests. As a result, in regard to the evaluation of tri-syllable articulation with varying speech rates, we recognized a trend in which the effect on the length of reverberation, the presence of discreet echoes or other changes in the time structure could be evaluated as the differences in the test results. Meanwhile, in regard to STI, we confirmed that, in some cases, differences in "ease of hearing" cannot be reflected as evaluation results in sound fields with long reverberation time or in sound fields affected by directional discreet echoes.

    The purpose of this research is to evaluate residential floors focusing on the walking feeling and to clarify the relationship with floor impact sound insulation and other physical properties. We conducted walking sensation evaluation tests on typical floor covering structures currently being used as residential floors and, calculating the psychological scale component values for floor hardness, walking ease, sensation of flexure, sensation of weight, preferability as a floor and other evaluation items, clarified changes in the values of the walking feeling of the subjects by age group due to changes in the floor covering structure. Furthermore, we developed a walking impact apparatus capable of accurately reproducing impact force properties of walking and examined the correspondence between the dynamic physical values of the floor obtained by using the apparatus and the psychological values obtained through the sensation evaluation tests. We thereupon identified the dynamic displacement values and dynamic spring constant values of the floor that provided the most favorable evaluation in terms of walking feeling.

    We have studied thermal environment in real-scale atrium. The heat budget of the room air and each surface of the indoor walls are examined from the measured temperature and so on. The room temperature is analyzed with the macro model. The following conclusion are obtained. (1) The error of total heat budged was about 5 percent of the total solar incident, so that the data obtained here are very effective to verify the mathematical analysis. (2) The heat gain from the structural frames is a very important factor for designing the atrium's indoor environment.

    Ventilation method in ventilated 30° pitched-roofs are examined to prevent icicle and ice dams forming on the inclined roof of insulated and airtight house. Simulation code that can be approximated measurement temperatures of the experimental house were developed, and was analyzed temperature of ventilating roofs with different insulation thickness and different ventilation method, under the several house location. From the simulation results, the effectiveness of the ridge opening is obvious, and the high insulation thickness can reduce ventilation rate. It also made clear that the ventilation rate of ventilating attic space is rather small for preventing icing at eaves, it especially means normalized opening at eaves or ridge on top should be made bigger anyhow from the architectural point of view.

    This paper describes a simple method to determine a window size and the shape of a room space for daylighting. To develop the method, we first derived a formula that relates the average daylight illuminance on the work plane to total interior surface area and the window area. In that course, the coefficient of daylight utilization (CDU), which corresponds to the coefficient of utilization appeared in the Lumen Method for electric lighting, was derived. The value of CDU was tabulated for easy use at planning stage. Using the diagram that we made, annual daylight illuminance near a window can be estimated. A couple of case studies was performed using the proposed method. The results were reasonable so that the determination of a window size and the shape of a room space for daylighting by the proposed method is applicable to architectural environmental planning.

    This paper describes a method to calculate "natural exergies" associated with solar radiation, effective radiation, evaporation of water and underground warm and cool storage. We first examined the variable types of so-called natural energy, which is a technical term widely used in the field of building environmental science, and then showed that they can be defined by the concept of exergy. We call this "natural exergy". The values of any natural exergies are positive. For example, stored exergy under the ground as a quantity of state is positive without exception. We calculated the annual amounts of natural exergies in Tokyo, and we tabulated the results as a chart that can be used to evaluate the regional climatic situation from the view point of exergy.

    The purpose of the study is to discuss the feasibility of a passive stack ventilation system using the beam space of a house as an air distribution chamber. The results of the calculation and the measured air flow rates in a test house are as follows 1) The proposed system requires less airtigthness than a direct air supply system using wall inlets. Designing stacks is easy in the proposed system because the height of the neutral zone is not influenced by the degree of airtightness. 2) In airtight houses, the distribution of fresh air and the ventilation routes can be well-designed using the beam space. The ventilation rate increased with the difference between the indoor temperature and the outdoor temperature. 3) In houses using a space heating system, the passive stack ventilation system fulfills the ventilation requirement during 90% of the heating season. And the ratio of the total ventilation volume to the ventilation requirement is 70%.

    Turbulent flow around a surface-mounted cube was analyzed by DSM (Differential Stress Model). This paper reports on the results of seven cases of DSM computations, using four different models for Φ_<ij>, two different models for Φ^ω_<ij> and two different models for D_<ij>. The accuracy of these computations was examined by comparing them with the results of wind tunnel experiment and LES. The following matters are clarified. The Craft and Launder (CL) model for Φ^ω_<ij(2)> improves the accuracy for predicting the k value in the area near the upwind corner of cube in comparison with the case in which Φ^ω_<ij(2)> is not included. The Mellor-Herring (MH) model for D_<ij> reproduces anisotropy of <u_i'u_j'> better than does the Daly-Harlow (DH) model.

    1.はじめに 建築構造物周りのように鈍い物体周りの剥離を伴う流れ場は、物体の形状と周辺圧力分布によって支配される。従って、建物周りの剥離流れを扱う場合、圧力場の予測精度と構造物周辺の格子解像度の両方が重要である。これに対して既報では、領域分割法の一つであるマルチブロック法と擬似圧縮性法との組み合わせを提案した。本報では、まず擬似圧縮性法特有の各擬似圧縮性パラメータの最適値について考察し、次にレイノルズ数22,000における正方形角柱周りの気流解析を行う。既往の実験データならびに計算結果との比較を通して、擬似圧縮性法とマルチブロック法の組み合わせによる剥離を伴う流れ場の予測精度を検証する。ただし乱流モデルを使用せず、数値粘性の影響を極力取り除いた層流計算を行うものとする。2.基礎式 擬似圧縮性法の基礎式は、連続の式に圧力の擬似時間微分項を加えたものと、運動方程式に速度の擬似時間微分項を加えたものからなる。これら基礎式を一般座標系を用いて表わした。3.計算手法 上記の基礎式を有限体積法を用いて離散化する。対流項は四次の中心差分に四次の数値粘性項を付加することで風上化を行う。また圧力式にも同様に四次の数値粘性項を付加する。時間微分項は、擬似時間に関しては陽的に物理時間は陰的に扱う。擬似時間刻みの値は、擬似圧縮性を導入したことで生じる擬似音速の値を用いて、各格子点毎に異なる値を与えることとした。流入流出境界条件として特性の方法を用いる。4.最適パラメータについての検証 一連の円柱周りの二次元気流計算を行い、擬似圧縮性パラメータの違いによる計算の収束に与える影響を調べた。収束が早くなる最適値は、物理時間刻みの大きさによって変化し、レイノルズ数を変えてもその傾向は変わらなかった。また、非定常空気力の時刻歴の比較から、擬似圧縮性パラメータの値は解の収束性には影響あるものの、流れ場には影響を及ぼさない事が判明した。さらに既往の考察を基に、最適な擬似圧縮性パラメータの値と物理時間刻みの関係について検討を行った。5.正方形角柱周りの気流解析 レイノルズ数22,000における正方形角柱周りの三次元気流解析を、乱流モデルを用いずに行った。対流項における数値粘性の影響を除去するために、同項にかかる係数を1/2(UTOPIAスキームの半分)とし、物理時間微分に関しては二次精度とした。また角柱周りの格子解像度の異なる三つの格子を用いて計算を行った。その結果、最も粗い格子を用いた場合を除いて、時間平均速度分布、特に角柱風下の逆流領域の大きさがLynの実験結果ならびに村上らによるLES計算結果と良く一致した。乱流モデルを用いない本計算によるこの一致は、角柱周りで生じる剥離流れの基本的な構造を捉えるだけの十分な格子解像度があった為と考える。さらにレイノルズ応力分布の計算結果も実験結果との比較的良い一致がみられた。6.結論 擬似圧縮性法を用いた物体周りの剥離流れの解析を行った。一連の円柱周りの二次元気流解析により、擬似圧縮パラメータの最適値は物理時間刻みと関連付けらることを明らかにした。また正方形角柱周りの三次元気流解析を行い、既往の実験結果や計算結果との比較的良い一致がみられた。これにより、擬似圧縮性法とマルチブロック法を組み合わせて用いることで、物体周りの剥離流れが精度良く捉えられることが示された。ただしこれらの解析は本解析手法の検証を目的として行われたものであって、乱流モデルの使用を否定するものではない事を付記する。

    In this paper the authors investigated the fundamental data which were necessary for estimation of the optimum number of the fixtures in a lavatory of the single-purpose soccer stadium. The sanitary fixture usage of the audience of a pro-soccer game at a stadium-K were surveyed actually by means of the electric methods. The results are as follows. The number of men was same to female in audience. The waiting line of lavatory during the intermission had been left after the second half of the game had started, therefore some of audience had been disturbed to watch the game. Lack of the sanitary fixture in the female lavatory had caused waiting line during this investigation period. But the occupated period on each fixture was similar to the result of the previous investigation.

    Significant air temperature rising in urban areas is well recognized as so-called Heat Island phenomenon in a global scale. It is qualitatively grasped that increase of anthropologic heat and alternation of land usage are regarded as its main reasons. To analyze quantitatively on factors of the significant air temperature rising, a predicting methodology combined with simultaneous solution for Architecture-Urban-Soil system was proposed. In the presented procedure, authors proposed simplified numerical calculation method for evaporation rate from soil was considered with building air conditioning load calculation and 1-dimensional heat balance model for an urban atmosphere. Using realistic input data assumed a typical urban area during summer season, a fundamental solution was obtained and an effectiveness of the proposed method was confirmed.

    In Japan, intermittent air-conditioning systems predominate, and it is thought that while designs need to take into account the thermal storage load for heating, the thermal storage load for cooling can be ignored because the effect is small. In this study, simulations were conducted on thermal storage load for cooling, taking into account the thermal sensation distribution. It was clearly established that a simulation can be used to evaluate the relationship between thermal comfort and thermal storage load for cooling, and that six times more energy was required at the start-up time on Monday than for continuous air-conditioning.

    The purpose of this paper is to analyze the principles of space formation of Madurese houses, house compounds and villages. In Indonesia, many settlements of Proto-Malay tribes like Batak, Toraja are formed as parallel disposition pattern. Madurese settlements also follow the same pattern. Compared to the settlements of other tribes, Madurese settlements are significant as a prototype because they realize that pattern in the smallest scale. It is also pointed out that Javanese and Balinese settlements in pre-Hindu period followed the same pattern. The analysis on Madurese settlements might reveal the basic rules of space formation of the settlements in Indonesia. This paper firstly tries to grasp the settlement patterns in rural regions in Madura Island. After looking at all the regions in Madura Island, Sanggra Agung is chosen to be surveyed more specifically. Judging from the result of the survey, it is concluded that Islamic influence has played an important role to keep indigenous space formation system of Madurese settlements particularly in western Madura.

    In this study, the correspondence between people's behaviors and their utilization of the spaces in the dwelling are discussed through examining their time allocations. This paper presents the process of examinations of connections between each type and attributes, and between types. (These types have obtained by classifying the people's behaviors and spaces through the feature of time allocation.) For examinations, the correspondence analyses of cross-classified tables and multiway contingency tables was used. The result was, as for correspondences of the behavior's types with the space's, that the peculiar types were identified from the common types, and that the attributes as background of the correspondences made clear.

    The purpose of this study is to introduce a new "degree of openness" concept as a comprehensive index for evaluation of space of a nursery school environment, so that the environmental space of a nursery school most conducive to the development of mind and body of children may be more fully comprehended. Firstly, a survey, undertaken at nursery schools in the cities of Nagasaki and Fukuoka, is summarized regarding the behavior of children when they try to have access from a classroom to a garden. The results of the survey indicate the importance of, among others, the size of a garden, which enables children to play as freely as possible, and the windows and exits of a classroom that may entice children from a classroom to a garden. It is to be shown, then, that the graduated degrees of "openness of access" from a classroom to a corridor and then to a garden has an important bearing on the development of exploratory behavior of children. It is finally shown that an analysis made by the regression analysis method of the principal components will certify the effectiveness of the "degree of openness" concept.

    This study is to extract "landschaft", and to grasp and type their characters with the approach of landscape ecology. The objective area is the western part of Saitama prefecture. We set up the three dimensional indicator used land-use and relative height in national land-use digital information and classified the areas of the homogeneous landscape. Furthermore, we make clear the relation between the indicators about population, socio-economy and space, and "landschaft". As a result, it is grouped into 7 types of "landschaft". These "landschaft" cover the rural communities as micro planning units. On the other hand, they divide municipalities as comprehensive planning units. Moreover, "landschaft" is formed by the spatial character of country side, and the problems of planning for each "landschaft" should arise from these characters.

    The purposes here are to conclude our researches about urbanizing process of privately owned land in readjusted area of Tsukuba New Town for these 22 years, and to consider the contributing factors of this trend. The movement of the urbanization there has been quite stable. They may be divided into three stages: 1) The first is stable urbanizing process before EXPO '85; 2) The second is rapid urbanization in the period of EXPO '85 and stagnation after that; 3) The third is ascending period with the actualization of urban potential after 1990. The growth and the completion of the city center was the main factor of these trends. EXPO '85 contributed to the maturity of the city center, and facilitated the urbanizing process later on.

    The purpose of this study is to present an expected value of the minimum length of the network connectivity among cities. We study two patterns. One is the minimum spanning tree on the n-points scattered on a rectangle. The expected value of the length is between 0.578√<n> and 0.707√<n>. The measured value is about 0.68√<n> by using computer. Another topic is the hierarchical tree on the n-points scattered on the p-areas divided rectangle. When the relation is p^3=(n/2)^2, the length of the hierarchical tree can be minimized.

    The purpose of this study is to show the urban transition of Tokyo from the point of view of the property ownership system of 1912. An early study done by Yoshojiro Takeuchi entitled "The Large-scale Landlord in Tokyo" which appeared in the Heimin Newspaper in 1907 analyses the property ownership system of Tokyo. The present study uses Takeuchi's first study as a guideline for research and comparison purposes. The aim here is to clarify the divisions of real estate in Tokyo and, by studying the impact of various property ownership systems, present guidelines for future urban development strategies. In this study, the author divided property ownership types into five categories. These categories are based on the ratio of the ownership of one's own residence to the ownership of other(s) properties, then divided into the different social classes. The discovery is that the former feudal lords of the Meiji Era still had huge land holdings, yet there was no concept of urban structure or city planning, thereby creating a congested city form.

In the new method, we use genetic algorithm with variables of manpower and days by which jobs are delayed to start from the earliest start times. Example problems are solved to show that the method is effective and efficient for non-repetitive construction works as well as repetitive ones.

    In this paper the building arrangiment of Parmanent Imperial Palace and the upper class aristocratic residences is analyzed through the documents of the completion celebrating ceremony, to make clear the difference between them in Heian era. In Parmanent Imperial Palace, Jijuden located at the north side of Sisinden(main buildimg) was used as the main space in the completion celebrating ceremony. But in most of the temporary Imperial Palaces as well as the upper class aristocratic residences Sinden(main buildimg) was used as main spase. This shows the particularity of Parmanent Imperial Palace on the building arrangiment.

    We can findout 26 Yashiki-hinagata (sourceebooks of Japanese mansion design in architectural reference books), which give descriptions of NO-stage design. In this paper, we introduced bibliography of the 26, analysed their theoretical and historical characteristics. As a result, we recognized that time of completion of design theory for NO-stage is about Kannei 15 (1638). Related with the historic backgrounds of perfection of NO at Shikisyou-suki-onari, design theory of NO-stage was dealt as an orthodoxy of house design and needed. Moreover, publication of "Shinpen-buke-hinagata" in Meireki 1 (1655), the design theory of NO-stage showed repercussions on Yashiki-hinagata after the middle Edo era.

    序:パルテノンの神室(cella)を囲む壁体には全く窓がないので、かつてその採光法に関する諸説が数多く提出されたが、今日ではいずれも根拠のない憶説としてしりぞけられ、採光は東の戸口からのみであったとするDopfeldの見解が定説となっている。ところが、採光法についてはもう一つの説があった。それはパルテノンの視覚補正について精密な調査を行ったPenroseによるもので、彼はパルテノンの屋根はParos島産の大理石で葺かれていたとし、その実測図を掲げるとともに、この大理石の透光性が神室の照明にも有効であったと指摘した。しかし、その後パルテノンの瓦は地元Penteli産の大理石であることがはっきりしてからは、この説も顧みられることがない。だが筆者はパルテノンの大理石瓦が野地板や葺き土の上ではなく、直接垂木の上に置かれていた事実にもっと注目すべきだと思う。Robertsonによれば、大理石瓦は紀元前6世紀に現れはじめ、5世紀以降には主要な神殿においてテラコッタ瓦に取って換えられたという。紀元2世紀のPausaniasは大理石瓦はNaxosのByzes(紀元前6世紀初めの人)が発明したと記しているが、このことは上記の考察と一致している。Naxos島の大理石はギリシア・アルカイソク期の彫像の素材としてよく知られている。Naxos・Paros・Penteliなどの白大理石は、石灰岩が変成作用を受けて、粗粒または微粒の方解石(カルサイト)の集合塊となった結晶質岩石であって、一定の透光性を有している。したがって、古代ギリシアの神殿の屋根瓦に使用されたとされるこれら3種の大理石の透光性をまず検証する必要があろう。そこで筆者は先行研究の調査結果をもとにパルテノンの大理石瓦の形状・寸法・構成を模型(縮尺:1/2)で復原するとともに、現地に赴いてNaxos・Paros・Penteliめ大理石試料を入手し、その受光面直下の照度から各試料の透過率を測定した。そしてこのデータをもとに神室内の照度を模型によって再現する実験を試みた。屋根瓦の形状・寸法:屋根の傾斜部分を構成する大部分の瓦はコリント型と呼ばれるもので、縁の部分に立ち上がりのある平瓦(flat tile)とその間を覆う角瓦(ridge tile)から成っている。垂木の上に直接置かれる平瓦は幅69cm、長さ77cm、平底部分の厚さ4cmで、表面は磨き仕上げ、裏面は瓦が垂木に固定するように瓦桟のかたちに合わせて整形されている。また上下の瓦が重なる部分には気圧差や毛細管現象による雨水の浸入を防ぐための微妙な水返しや水切りの加工も施されていた。角瓦の長さは平瓦とほぼ同寸であるが、Orlandosの復原によれば、幅は24cm(A型)と35.5cm(B型)とがあったようである(図1・2・3,写真1)。大理石試料の特性:M1(Naxos)・M2(Penteli)・M3(paros)はすべて98%以上カルサイトで構成されている。まずM1はVitruviusがいう結晶岩塩のような外観を呈し、5mm以上の粒子を含む粗粒塊であって、高い透光性が認められるが、劈開性が大きいために、角欠け・ポロっき・割れなどの加工上の欠点を伴う。M3は0.2mm〜0.3mmの微細粒の緻密な集合塊であって、精巧な彫刻的表現には適するが、吸水率はM3>Ml>M2と最も高いので、耐候性は劣る。M2は平均0.5mmの標準的な細粒から成り、その物理的・機械的性質は優れている。しかし、緑泥石や雲母系の鉱物をわずかに含むため、薄い銀緑色の縞模様が見られる(表1,写真2)。ギリシア彫刻におけるアルカイック期から古典期への表現形式の発展は、その素材としての大理石が、NaxosからParosへ、そしてPenteliへと移行するのと密接に関連しているが、それはまさに3種の大理石の各々の特性に基づく選択であったと考えられる。そしてこのことは建築についても同様であって、パルテノンでは、それまでの神殿の彫刻的部分にはParosが好んで用いられた伝統を改めて、敢えて彫刻を含むすべてのエレメントにPenteliが使用された。それは総監督Pheidiasが材料の耐久性を最優先したからであろう。特に屋根瓦についてはそうであって、その精巧なディテールには、素材の加工性・耐久性・透光性について幾多の改良と選択が重ねられたことが推測される。大理石試料の透光性:M1(Naxos)、M2(Penteli)、M3(Paros)の各種の大理石について、厚さ約1・2・3・4cmの試料(16cm角)を用意し、これを外光を遮断した暗箱の1面にセットし、外部の照度と内部の試料直下面の照度を同時に読み取り、その比(%)を各試料の透過率とした。このテストの結果は図4に示すとおりであるが、4cm厚の試料では、M1は0.40%、M2は0.23%、M3は0.02%で、これまでのParosは透光性が高いという、外見上からの判断を全く覆すものであった。しかし、これは結晶光学の現象として理解されることで、粒子が細かい集合塊ほど、光は多く拡散、吸収されるからである。また透過光の色はM1は白色に近く、M2は黄色、M3は暗褐色であるが、これも粒子が微細であるほど、波長の短い光線のエネルギーは減衰し、透過光は赤色ゾーンのスペクトルが相対的に強まるからであろう(写真3)。ともあれNaxosのきわめて高い透光性は、そもそも大理石瓦の使用が採光を目的とするものであったことを証明している。ところが、Naxosは加工性の劣る素材であったので、のちにオリンピアのゼウス神殿のように平瓦はほとんどPenteliに葺き替えられたのである。Parosは屋根のむしろ彫刻的な部分に多く使われたのではないかと思う。神室の採光の復原:パルテノンに使用されたPenteli大理石には縞模様の目立つものも含まれていたようなので、M2と同種の試料(51×16×4cm)について透光性を上記の方法で調べたところ、平均して透過率0.033%、裏面輝度10cd/m^2、色度はCIEのx・y表色系色度図においてx=0.57、y=0.4の値を示す橙色光であった(写真4)。またこの測定値をもとに、神室の屋根面の光源を水平な等輝度均等拡散面と仮定した場合、神室の身廊中央床面P点の照度E_p,を、E_p=π・C・L(C:立体角投射率、L:光源の輝度)の等式によって試算したところ、E_p≒2.9 lxを得た(図5,6)。そしてさらにCは光源の形状・大きさと受照点Pとの位置関係で決まる幾何学的数値(比率)であるという理論的根拠に基づいて、神室部分の精確な模型(縮尺1/40、写真.5)を作製し、これによって神室内の照度の分布および変動を観察した。模型の屋根面は採光に有効な平瓦の部分を塩化ビニール板(表白、裏榿色)とし、その透過光の色が上記CIEの色度に近似するようにした。実験はまず外光を調節して、屋根面直下の照度を約33 lx(輝度10cd/m^2に相当)に設定し、遮蔽された神室内の所定の位置P点に照度計の受光部を置いて測定した。その結果は、E_pと同位置で約8.25 lxとなり、計算値2.9 lxをかなり上回った。言うまでもなく、これは神室内全体の反射光の影響と、左右の側廊と後廊上部の屋根面からの採光が加わるためである。また屋根面直下の照度を33 lxから6 lxまで徐々に低下させた場合、同位置の照度の変動はほぼ直線的に下降することも確認された(図7)。結語:Pellteli産大理石表面の反射率は72%、模型(石膏)のそれは約90%であるから、神室中央床面の照度は、晴天時(100,000 lx)において約7 lxである。少なくともこれだけの照度が得られたとすれば、パルテノンの大理石瓦も採光のためであったことになる。つまりコロネードに囲まれた部分には天井はなかった蓋然性が高いのである。しかし最近遺構調査を行ったKorreg氏は神室の東の壁の左右に窓があったと報告している。筆者はその復原図に基づいて、プロナオスとそのポーチコ部分の模型を製作し、この窓からの採光の影響についても実験すべく作業を進めている。ともあれ、神室の天井の問題に関しては、これら一連の実験結果を考慮した議論がなされることを期待したい。

    Through twenty two of the poems in "The collection of Myoue's poems", we interpret the meaning of Myoue's dwelling place for buddhistic practices in Kozanji-temple. "Kekuden (Myoue's pavilion where he sat for religious meditation)" was the most important place in his dwelling. The meaning of the place was made clear by naming or by making poems on the mood/atmosphere (Stimmung) of the place. In this place Myoue could see "the truth on two kinds of emptiness", and realize how one should think about one's dwelling place in the true meaning.

    It has often been pointed out that the quality of houses in Japan is inferior to that in Europe and America; however, houses are a reflection of culture, and the evaluations of houses vary according to the curture. This paper examines the reasons why the very simply built, dilapidated mountain huts lived in by hermits in medieval times in Japan were evaluated as ideal houses in classical Japanese poetry.

    Mies's swan song, the New National Gallery(1962-67)is so simple as if to symbolize his architecture. But the proportions of the New National Gallery are copied from the privileged set of proportions of his earlier Bacardi Office Building project(1957-6O). The privileged set of proportions is derived from the four factors : the accident that the Bacardi was designed earlier, the rational modular system, Mies's own sense of proportion, and the agreement with Golden Ratio and Dynamic Rectangle. It is very interesting that Golden Ratio and Dynamic Rectangle are found in the proportion of the elevation of Mies's swan song.

    This research is a trial to make the concept of the 'contextualism', which has been pursued widely in America during the last three decades, clear. This paper reexamines the transition of the concept of 'context' in the American architectural thought from 1960 to early 1970's. Until the mid-1960's, the word 'context' became used at the level of physical environment. At that time, the concept of the 'contextualism' arose out of seeing cities as both buildings and spaces; it was conceived as a set of strat-egies for building in cities and it proposed the continuity between adjacent buildings. Although after the mid-1960's, when many critical writings about modernism were published, the word 'context' became used at the level of semantics of environment gradually.

    This study was disclosed by the behavior of visitors at waterfront parks. The behavior of visitors was understood by non-participant observation. This was investigated at different four areas ; Kasai Seaside Park, Rinkoh Park, Yamashita Park, and Takeshiba Marine Park. The result of investigation, it could obtain 954 samples at four areas. It analyze principally the locus of walk and behavior range. The result of analysis, the visitors behave along the edge of water. This was proved the behavior range of 350 meters along the seaside, 50 meters off the shoreline. Therefore the waterfront park is more necessary the improvement of the long and narrow form than the size.
