주거환경에서 거주자의 '시각만족(residents' satisfaction with visual appearance)은 더 큰 추상적 개념인 '주거만족'(residents' housing satisfaction)과의 밀접한 인과적 관련(Francescato et. al., 1979) 때문뿐만 아니라 인간 기본 욕구 중의 하나인 미적 욕구의 충족과 관련되어 있다는 점(Chin, 1991)에서도 중요시 되어야 할 이론적 개념이다. 본 연구에서는 거주자의 시각만족을 종속지표로 보고, 다양한 영향 가설변수들과의 인과 적 관련도를 경로분석(path analysis)을 통해 검증하고 있으며, 어떤 변수 가 어떤 이유(경로)로 또는 얼마만한 크기로 거주자의 시각만족에 영향을 주는 가가 중점적으로 토의된다. 한국의 6개 대단위 주거단지로부터 다단 계표집 방법과 설문면담 방법을 통해 646명의 응답이 수거되었다. 분석의 첫 단계로써, 다수의 설문문항을 본 연구의 가설 변수로 집약하기 위한 요 인분석(factor analysis)이 사용되었고, 요인 분석으로부터 추출된 변수들간 의 인과적 관련도를 검증하기 위해 최종적으로 경로분석이 사용되었다. 본 연구의 결과를 요약해 볼 때, 본 연구의 가설 변수 대부분이 최종 종속변 수인 거주자의 '시각만족'에 유의한 인과 영향을 보이는 것으로 나타났으 며, 구체적으로 '시각적 무질서'(visual disorder), '시각적 단조로움'(visual monotony), '단지 과밀감'(development crowding) 등이 부정적 영향을, '시 각적 매력'(visual attractiveness)과 '인근 자연녹지의 존재'(presence of nearby natural environment)등이 긍정적 영향을 미치는 것으로 파악되었 다. 그 외에도 '옥외공간이용 편리'(outdoor or recreation convenience)와 ' 이웃만족'(satisfaction with neighbors), 그리고 '주거환경 유형'(building type, building arrangement type)등도 유의한 인과적 관련을 보이므로써, 기존 문헌들이 제시하고 있는 것보다 훨씬 다양한 변수들이 다양한 경로를 통해 거주자 시각만족의 영향인자가 될 수 있는 가능성을 제시하고 있다. 가설 변수의 하나인 '길찾기의 난이 정도'(difficulty of way-finding)와 종 속변수간에 유의한 관련도가 나타나지 않은 이유로 길찾기 변수가 '시각만 족'보다는 거주자의 '안전만족'(safety)과 관련된 변수일 가능성도 아울러 지적되었다. 본 연구의 결과로부터, 주거 계획 및 설계분야 그리고 추후 관 련 연구 분야를 위한 여러 제안들이 제시되었다.

Gwaneumhyeonsanggi is a writing of praise of the incarnated White-robed Gwanseumbosal by Choi Hang which King Sejo witnessed at the top of Damhwajeon during his visit to Sangwonsa Temple. In Gwaneumhyeonsanggi, White-robed Gwaneumhwahyeondo drawn by a painter is attached, which demonstrate the feature of Sangwonsa temple in the early Joseon period. This study aimed to examine the landscape features of Sangwonsa in the early Joseon period by records and picture in Gwaneumhyeonsanggi. As a result, it was determined that the building display, spatial structure, building type and landscape arrangement seemed to be unique compared with other temples. In particular, the treatment of scenic stone(景石) is important in terms of landscape because it complements existing ideas and concepts that the temple landscape was mainly made of water as the main resources. Also the trees around the temple shown in the picture in can be compared with the current state of the data is valuable.

Architectural researches on the traditional houses of Korea have been studied mainly based on the data collected in the field survey. From explosively incresed real mesurements and drawings in the field, plenty of data have been collected. Those have been the basic data for verifing and developing the theories on the traditional house. But after Korean war the researchers in South-Korea were not able to approach to the field in North Korea, so the new data of North Korea were not added any more. The poverty of real data have caused regional unbalance in the researches. This paper aims at collecting new data of traditional house in North Korea. But still being prohibited for the researchers of South Korea to approach to the field, I had to depend on the memories and experiences of the immigrants from North Korea who are now living in Kyon-Nam and Pusan Province. Through the questionnaire and drawings, they described vivid memory of their old houses. I was able to collect the data of 71 cases, which are significant and valuable as much as those of the real field are. The data include the address and site condition, family structure, economic condition, construction period of each house, The drawings by themselves show the building forms and plans, the plans of each building, and the included spaces. Although the quantity of those data is not enough for statistical analysis, it shows general tendency for analizing regional charateristics, the differnces among economical classes, and the periodical change. It opens the way for verfying the existing theory. Analizing the data, I have some conclusions as followings: a. Most of researchers have classified the dominant housing type of Hamkyong-Do as 'the double fold' type. In this study, all cases of Hamkyongbuk-do also show 'the double fold plan with Chongju-kan'. But in Hamkyongnam-do some cases show 'the double fold plan without Chongju-kan, or projecting the stable into the yard, which seem to be different type from 'the double fold plan with Chongju-kan' b. Existing theories classified the dominant housing type of Pyongahn-do as 'two buildings with pararell arrangement'. This classification is verified with the plentiful cases in this study. Futhermore, I found new tendency, that is, getting higher econnomic condition, they construct annex buildings between the main buildings. Finally their houses show 'scattered ㅁ shape'. The houses included in this two types has narrow and closed inner yard, which is different from the houses of the same shape in the south region of Korea. c. Existing theories classified the dominant housing type of Hwanghae-do as 'ㅁ sape with Daechong' type. I found many cases of 'ㅁ shape', but only two cases show 'Daechong'. 'The doble fold' type was also founded. Unfortunately very few cases were sent from Hwanghae-do, it is not enough for finding general tendency.

At a time of growing importance of safety management in the social welfare facility by the increase of social welfare facilities, this study analysed safety perceptions about facility management, facility conditions, and facility structure and arrangement. This study sample consisted of 204 service providers and service users in 12 social welfare facilities. T-test and ANOVA were used to find the group differences among facility types. The findings were as follows. Firstly, safety perceptions of the service providers were significantly higher than those of service users in terms of facility management, and facility structure and arrangement. Secondly, in terms of facility types, the respondents in the family service center had lower safety perceptions than the respondents in other service in all three areas. Thirdly, facilities that are of 10 years or older had higher safety perceptions than the respondents of facilities that are 6 to 10 years old in the area of facility management, and facility structure and arrangement. Fourthly, in regard to building heights, the respondents in 3 to 4 story facilities had statistically higher safety perceptions than respondents in 1 story facilities. Finally, looking at the relationship between floor area and safety perceptions, safety perceptions of the respondents of less than $400m^2$ facilities or $600m^2$ and more facilities were significantly higher than those of $400m^2{\sim}$ less than $600m^2$ facilities.

Infill panel is the first element of a building subjected to blast loading activating its out-of-plane behavior. If the infill panel does not have enough ductility against the loading, it breaks and gets damaged before load transfer and energy dissipation. As steel infill panel has appropriate ductility before fracture, it can be used as an alternative to typical infill panels under blast loading. Also, it plays a pivotal role in maintaining sensitive main parts against blast loading. Concerning enough ductility of the infill panel out-of-plane behavior, the impact force enters the horizontal diaphragm and is distributed among the lateral elements. This article investigates the behavior of steel infill panels with different thicknesses and stiffeners. In order to precisely study steel infill panels, different ranges of blast loading are used and maximum displacement of steel infill under such various blast loading is studied. In this research, finite element analyses including geometric and material nonlinearities are used for optimization of the steel plate thickness and stiffener arrangement to obtain more efficient design for its better out-of-plane behavior. The results indicate that this type of infill with out-of-plane behavior shows a proper ductility especially in severe blast loadings. In the blasts with high intensity, maximum displacement of infill is more sensitive to change in the thickness of plate rather the change in number of stiffeners such that increasing the number of stiffeners and the plate thickness of infill panel would decrease energy dissipation by 20 and 77% respectively. The ductile behavior of steel infill panels shows that using infill panels with less thickness has more effect on energy dissipation. According to this study, the infill panel with 5 mm thickness works better if the criterion of steel infill panel design is the reduction of transmitted impulse to main structure. For example in steel infill panels with 5 stiffeners and blast loading with the reflected pressure of 375 kPa and duration of 50 milliseconds, the transmitted impulse has decreased from 41206 N.Sec in 20 mm infill to 37898 N.Sec in 5 mm infill panel.

The paper presents the details and results of an experimental study on bolted end-plate joints of industrial type steel building frames. The investigated joints are commonly used in Lindab-Astron industrial buildings and are optimized for manufacturing, erection and durability. The aim of the research was to provide an experimental background for the design model development by studying load-bearing capacity of joints, bolt force distribution, and end-plate deformations. Because of the special joint details, (i.e., joints with four bolts in one bolt-row and HammerHead arrangements), the Eurocode 3 standardized component model had to be improved and extended. The experimental programme included six different end-plate and bolt arrangements and covered sixteen specimens. The steel grade of test specimens was S355, the bolt diameter M20, whereas the bolt grade was 8.8 and 10.9 for the two series. The end-plate thickness varied between 12 mm and 24 mm. The specimens were investigated under pure bending conditions using a four-point-bending test arrangement. In all tests the typical displacements and the bolt force distribution were measured. The end-plate plastic deformations were measured after the tests by an automatic measuring device. The measured data were presented and evaluated by the moment-bolt-row force and moment-distance from centre of compression diagrams and by the deformed end-plate surfaces. From the results the typical failure modes and the joint behaviour were specified and presented. Furthermore the influence of the end-plate thickness and the pretension of the bolts on the behaviour of bolted joints were analysed.

This study is a case study to identify the spatial composition and structural problems of existing schools for spatial innovation as a future school that can operate a credit system for old high schools and establish a mid-to-long-term arrangement plan as a credit system operating school capable of various teaching and learning in the future. The study results are as follows: First, most of the problems of the old high schools entailed that there was very poor connectivity between buildings as most of them were arranged in a single, standard design-type unit building and distributed in multiple buildings. In addition, the floor plan of each building is suggested to be a structure in which student exchange and rest functions cannot be achieved during the break period due to the spatial composition of the classroom and hallway concepts. Second, in the direction of the high school space configuration for future school space innovation, the arrangement plan should be established by reflecting the collective arrangement in consideration of the shortening of the movement route and the expansion of subject areas due to the movement of students on the premise of the subject classroom system. Moreover, it is desirable to provide a square-type space for rest and exchange in the central area where communication and exchange are possible according to the moving class. Third, as the evaluation criteria for relocating old high schools, a space program is prepared based on the number of classes in the future, and legal analysis of school land use and land use efficiency analysis considering regional characteristics are conducted. Based on such analysis data, mid-to-long-term land use plans and space arrangement plans for the entire school space such as the school facility complex are established.

The housing market is now difficult because of excess of the increase rate of housing and long-term recession but high-rise mixed-use buildings can mix residential facilities with various demand facilities focusing and they have the advantages to secure open space and excellent view by high-rise apartment. But there are problems by hindrance of skyline formation and height of buildings. Therefore, the purpose of this study is to suggest the height standard and the slenderness ratio to location types of Mixed-use Residential Tall buildings. For the method of the study, term arrangement through literature search and the precedent research survey were first done, the level of urban design and the details related to the height of buildings were done as the case research focusing on the 16 cases in Seoul. The following results were drawn by suggesting the height standard and the slenderness ratio by location type based on them. First, the height of mixed-use building by location type in the level of urban design gets higher starting from the secondary center of the city and can be suggested as from less than 150m to more than 200m. Second, the slenderness ratio shall be planned as more than 1:3 because the area of the ground level of mixed-use building is large unlike Mixed-use Residential Tall buildings and visual passage shall be placed so that unity of openness and group formation will be planned. Third, for the height related to Mixed-use Residential Tall buildings, amendment of the special architectural district system and the special law related to super high-rise buildings shall be enacted.
