The gate of university can be the first impression of the University itself and most important advertising structure which is more than just a structure that people pass by. It can also be the medium that connects the outside with the inside of the campus. Therefore, many universities are willing to have a unique and symbolic gate of their own. Recently, university representatives have become interested in arranging external areas of the campus. At this respect, studying and researching university gates and surroundings facilities must be realized. We visited 104 different universities gates to research and survey people about what they think of the internal and external individuality of each gate. According to these researches we established a full data base of 24 types of classifications, 5 characteristic forms of each shapes, 8 forms of the symbolic characteristics of university gates and 10 surroundings facilities of the university gates.

This study reviewed the planning characteristics of contemporary Japanese middle school architecture on which related studies are insufficient, aiming to obtain new ideas for planning Korean middle school facilities. Fourteen case schools built after 1990s were selected and analyzed. They were divided into learning-living space and other major spaces. The planning characteristics of the case schools are summarized as follows 1) The case schools were classified into two categories, departmentalized classroom type (D type) and usual with variation type (UV type) by school system. These categories can also be the classification standard for basic architectural characteristics in learning and living space of case schools. 2) D type case schools have departmentalized classrooms, home base, media space and teacher's space for learning-living space. D type case schools are divided into 'attached-to-classroom type' and 'separate type' depending on the adjacency of the home base and departmentalized classroom. 3) UV type case schools have multipurpose space around the classroom for learning-living space and can be divided into two types, i.e., 'directly adjacent' and 'separate', depending on the connectivity to classroom of multipurpose room. 4) Specialized classrooms are designed to have the openness to the public and the own characteristics of school subjects strengthened and show the spatial differentiation with connected ancillary spaces. 5) Libraries are designed as complex zones grouped with computer labs, audio visual rooms and multipurpose halls not as a single room and as open plan not with a closed wall. 6) The gymnasium is the basic sports facility with a martial arts room and outdoor pool, which are for after-school activities as well as physical education class. 7) The terrace, balcony and outdoor stairs are frequently used architectural vocabularies as diverse outdoor spaces with a variety of functions.

This study analyzed the perceptions of teachers to establish the direction for managing the space outside an elementary school. Satisfaction with outdoor school spaces is influenced by the satisfaction with tree and flower plantation and outdoor rest spaces. This study found that the longer the working years of a teacher, the higher their awareness of the importance and necessity of outdoor spaces in the school. Respondents emphasized the lack of manpower and budget, as well as the indifference of the administration as hindrances to the management of outdoor spaces in the school. The outdoor space in the school should include a secure play area, plant education space, class practice spaces, and a rest area. Furthermore, the space outside the elementary school should support learning, playing, and resting. To this end, facilities such as benches, pergolas, outdoor classrooms, ecological ponds, farms, and flower beds should be provided. In an outdoor space, plants featured in textbooks, seasonal plants, and those that provide shade can be planted along with labels to provide information and thereby promote learning. The teachers expected that the management of the external space will have an educational and emotional effect on students. In response to the innovation of the school spaces, it is necessary to continuously manage the external spaces to achieve educational and emotional effects by organically connecting the outdoor spaces with the indoor space. For this purpose, it is required to provide support for securing budgets and manpower, and to introduce relevant policies.

Signboards are installed in different types and sizes depending on the shop characteristics. However, the local government is having difficulty managing signboards with frequent opening and closing of stores and insufficient management personnel. In this study, a methodology was proposed to standardize and efficiently manage signboard information. To this end, the signboard display method of the enforcement ordinance related to outdoor advertising was analyzed to define the attribute elements of standard signboard data. In addition, physical information of signboards was obtained through signboard recognition technology, which is a prior study, and attribute elements of signboard standard data were defined through information that can be read with the naked eye, building integration information of the Ministry of the Interior and Safety, and street name address. In order to standardize the signboard information by spatial characteristics, data product specifications and metadata were defined according to the national spatial information standard. Lastly, standard data for signboards were produced in XML (Extensible Markup Language) format for compatibility, and XSD (XML Schema Definition) was defined for XML integrity so that data validity could be verified. Through this, a standard data model for the informatization of signboards was designed.

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.

This study was designed to suggest a landscape agreement in order to effectively preserve historical and cultural landscapes at this point of time when many landscape agreements are being concluded for landscape management, to analyze landscape management methods according to the problems of comprehensive and widespread landscape agreements and landscape types and to generalize landscape agreement contents. To begin, sustainable and practical landscape management plans that local people can themselves participate and carry out were proposed, based on historical and cultural landscape preservation guidelines extracted from the consideration of domestic and foreign cases about landscape management by citizen autonomy and participation. The guidelines considered what regional residents would follow by themselves, as well as what should be considered with regard to the accessibility and symbolism of a building's appearance and external spaces designed with the motif of historical and cultural landscapes. The guidelines also pay attention to the maintenance management of outdoor advertisements and facilities in order to maintain a pedestrian-friendly street environment which pursues designs in harmony with the existing historical and cultural landscapes. In addition, the recommended guidelines that are considered less important,are restricting the sizes of buildings, encouraging maintenance management of the details and external spaces to hide building facilities and block them from being exposed and including information about the use of nature-friendly materials, and the management of neon signs in the landscapes and lighting time during the night. These results demonstrate that local residents need to improve the landscapes and change their consciousness by themselves to maintain the historical and cultural landscapes with a sense of tradition.

This study was to analyze the changes made in the landscape cognition in Yong-in City for the past 10 years. For the analysis, the landscape plan in 2001, and the survey data collected for the new 2012-landscape plan were used. The questions on the survey covered the cognition of the current landscape status, the evaluation of landscape depending on the types of landscape, the understanding of each element on the landscape, the residents' cognition, etc. In the evaluation of the status on current landscape, Everland was ranked outstandingly high as a symbol and a representative place both in 2001 and 2012. The image of the overall city landscape was changed from the image of unique, diverse, grand-scale and well ordered in 2001, to the image of wide, disordered, common and realistic. As the evaluation of individual landscape types such as the view of the mountain, the surroundings of the tourist attractions, colors, etc, has improved overall. The image of the city has been evaluated to improve gradually, especially in the level of individual element. In the study of participating the willingness of residents, despite the interest in landscape has been continued, the attitude for the actual participation in the action plan or the restriction of property right has been changed into a negative side. For the direction of the landscape plan, the residents are more interested in the detailed subjects : such as the financial support, the night landscape plan, the improvement of the problems, etc. During the last 10 years, the changes on the landscape cognition in Yong-in City have changed more in detail and specifically, the cognitions on the local government and developers changed positively. However the reducion of the participants' willingness suggested a review on the policies and the projects of the landscape.

The safety related components in the nuclear power plant should be designed to withstand the seismic load. Among these components the integrity of reactor internals under earthquake load is important in stand points of safety and economics, because these are classified to Seismic Class I components. So far the modelling methods of reactor internals have been investigated by many authors. In this paper, the dynamic behaviour of reactor internals of Yong Gwang 1&2 nuclear power plants under SSE(Safe Shutdown Earthquake) load is analyzed by using of the simpled Global Beam Model. For this, as a first step, the characteristic analysis of reactor internal components are performed by using of the finite element code ANSYS. And the Global Beam Model for reactor internals which includes beam elements, nonlinear impact springs which have gaps in upper and lower positions, and hydrodynamical couplings which simulate the fluid-filled cylinders of reactor vessel and core barrel structures is established. And for the exciting external force the response spectrum which is applied to reactor support is converted to the time history input. With this excitation and the model the dynamic behaviour of reactor internals is obtained. As the results, the structural integrity of reactor internal components under seismic excitation is verified and the input for the detailed duel assembly series model could be obtained. And the simplicity and effectiveness of Global Beam Model and the economics of the explicit Runge-Kutta-Gills algorithm in impact problem of high frequency interface components are confirmed.

This study was conducted to investigate the effects of pergola's shading on the thermal comfort index in the summer. The 3 type of pergolas($4m{\times}4m{\times}h2.7m$) which were screened overhead(I)/overhead west(II)/overhead west north(III) plane with reed blind for summer shading and winter wind break, were constructed on the 4th floor rooftop. Thereafter the meteorological variables(air temperature, humidity, radiation, and wind speed) of pergola I, III and rooftop were measured from 14 to 16 August 2013(1st experiment), those of pergola I, II and rooftop were measured from 26 to 28 August 2013(2nd experiment). The effects of pergola's shading on the radiation environment and mean radiant temperature($T_{mrt}$), standard effective temperature($SET^*$) were as follows. The maximum 1 h mean values of differences ${\Delta}$ of the sums of shortwave radiant flux densities absorbed by the human body (${\Delta}K_{abs,max}$) between pergola I, III and nearby sunny rooftop were $-119W/m^2$, $-158W/m^2$, those between pergola I, II and rooftop were $-145W/m^2$, $-159W/m^2$. The maximum 1 h mean values of differences ${\Delta}$ of the sums of long wave radiant flux densities absorbed by the human body (${\Delta}L_{abs,max}$) between pergola I, III and nearby sunny rooftop, were $-15W/m^2$, $-17W/m^2$, those between pergola I, II and nearby rooftop, were $-8W/m^2$, $-7W/m^2$. The response of the direction dependent long wave radiant flux densities $L_1$ on the pergola's shading turned out to be distinctly weaker as compared to shortwave radiant flux densities $K_1$. The pergola's shading leads to a lowering of $T_{mrt}$ and $SET^*$. The peak values of $T_{mrt}$ absorbed by the human body were decreased $16^{\circ}C$ and $21.4^{\circ}C$ under pergola I and III as compared to that of nearby rooftop in the 1st experiment. Those were decreased $18.8^{\circ}C$ and $20.8^{\circ}C$ under pergola I and II as compared to that of nearby rooftop in the 2nd experiment. The peak values of $SET^*$ absorbed by the human body were decreased $2.9^{\circ}C$ and $2.6^{\circ}C$ under pergola I and III as compared to that of nearby rooftop in the 1st experiment. Those were decreased $3.5^{\circ}C$ and $2.6^{\circ}C$ under pergola I and II as compared to that of nearby rooftop in the 2nd experiment. The relative $SET^*$ decrease in pergola II, III compared to nearby sunny rooftop $SET^*$ were lower than that in pergola I, revealing the influence of the wind speed. Therefore it is essential to design pergola to maximize wind speed and minimize solar radiation to achieve comfort in the hot summer. The $SET^*$ under pergola I, III were exceeded $28.7^{\circ}C$ and $30.4^{\circ}C$ which were the upper limit of thermal comfort and tolerable zone during all most daytimes in the 1st experiment(maximum air temperature $37.5^{\circ}C$). The $SET^*$ under pergola I was exceeded $28.7^{\circ}C$ which was the upper limit of thermal comfort zone at 13h, that under pergola II was exceeded $28.7^{\circ}C$ from 8h to 14h, meanwhile the $SET^*$ under pergola I, II were within thermal tolerable zone during most daytimes in the 2nd experiment(maximum air temperature $34.4^{\circ}C$). Therefore to ensure the thermal comfort of pergola for summer hottest days, pergola should be shaded with not only reed blind but also climbing and shade plants. $T_{mrt}$ and $SET^*$ were suitable index for the evaluation of pergola's shading effects and outdoors.
