The idea that a school could take a role of educating each community personnel as well as students and the school building could be a center in a community is discussed in this paper. Also, as rental housings being included in the community and placed near school buildings, school facilities can be shared and cover the shortage of social welfare facilities. Thus urban social facilities including schools, social and cultural facilities, and rental housings should be planned as a bundled scheme. The objective of this Paper is to find the suitability of building a complex of school, gymnasium, cultural facilities, welfare facilities in school sites, and building rental housing in public building sites, such as cultural facilities and welfare facilities, gymnasium sites in the City of Pyeong Teak. It is found that this assumption can be proved when building a public school of 6 to 7 story or a rental apartment with a floor area ratio of 150% - 200%.

Concerning about global warming due to emission of greenhouse effect gas like C02 and depletion of fossil fuels have been spreading. So the need for solar energy utilization is increased. It is essentially important to make efforts to reduce usage of fossil energy resources. In this study, we analyzed the correlation between climatic elements and the photovoltaic power generation. Cloud cover of the correlation coefficient was 0.93. The order of the correlation coefficient was average temperatures, hours of sunshine duration of sunshine and the humidity. To accurately analyze of the degree of correlation for the photovoltaic power generation, additional research about climatic elements that show a high correlation is needed.

Vibration-based structural health monitoring (SHM) is crucial for the dynamic maintenance of civil building structures to protect property security and the lives of the public. Analyzing these vibrations with modern artificial intelligence and deep learning (DL) methods is a new trend. This paper proposed an unsupervised deep learning method based on a convolutional autoencoder (CAE), which can overcome the limitations of conventional supervised deep learning. With the convolutional core applied to the DL network, the method can extract features self-adaptively and efficiently. The effectiveness of the method in detecting damage is then tested using a benchmark model. Thereafter, this method is used to detect damage and instant disaster events in a rubber bearing-isolated gymnasium structure. The results indicate that the method enables the CAE network to learn the intact vibrations, so as to distinguish between different damage states of the benchmark model, and the outcome meets the high-dimensional data distribution characteristics visualized by the t-SNE method. Besides, the CAE-based network trained with daily vibrations of the isolating layer in the gymnasium can precisely recover newly collected vibration and detect the occurrence of the ground motion. The proposed method is effective at identifying nonlinear variations in the dynamic responses and has the potential to be used for structural condition assessment and safety warning.

Magnetic flux sensors are commonly used in monitoring the cable force, but the application of the sensors in large diameter non-closed Galfan cables, as those adopted in Yueqing Gymnasium which is located in Yueqing City, Zhejiang Province, China and is the largest span hybrid space structure in the world, is seldom done in engineering. Based on the construction of Yueqing Gymnasium, this paper studies the cable tension monitoring using the magnetic flux method across two stages, namely, the pre-calibration stage before the cable leaves the rigging factory and the field tension formation stage of the cable system. In the pre-calibration stage in the cable factory, a series of 1:1 full-scale comparative tests were carried out to study the feasibility and relability of this kind of monitoring method, and the influence on the monitoring results of charging and discharging voltage, sensor location, cable diameter and fitting method were also studied. Some meaningful conclusions were obtained. On this basis, the real-time cable tension monitoring system of the structure based on the magnetic flux method is established. During the construction process, the monitoring results of the cables are in good agreement with the data of the on-site pressure gauge.The work of this paper will provide a useful reference for cable force monitoring in the construction process of long-span spatial structures.

본 연구는 칸톤학교 아라우가 19세기 전체에 걸쳐 독일의 김나지움 교육 이념 논쟁과 밀접한 관련이 있음을 보였다. 이 논쟁 속에서 아인슈타인이 바이에른에서 정규 과학교육의 혜택을 거의 받지 못했다는 점을 원전 자료 분석을 통해 입증했다. 아인슈타인은 정규교육의 결핍에도 불구하고 일찍부터 독학에 의해 자기 학습을 하는 습관을 가졌고, 이 방식은 평생 유지되었다. 그는 권위주의적이었던 뮌헨의 학교에서는 매우 힘들게 지냈지만, 자유정신과 자율성이 보장되었던 아라우의 민주적 학교에서는 정서적 안정감을 얻을 수 있었다. 아라우는 오랫동안 외지와 자유로운 교류와 프랑스 계몽주의 영향으로 종교적, 지역적, 민족적 차별이 없이 적대적 사상들에 대해 관대한 다문화적 사상을 갖고 있었다. 이로 인해 소규모 공립학교인 칸톤학교는 스위스를 넘어 교사와 학생의 막강한 인적 자원을 확보할 수 있었고, 교육이념 논쟁을 통해 시대정신에 맞는 실용주의와 계몽주의 사상을 선택했다. 이는 김나지움에서 인간교육-인문주의-엘리트 양성을 실시하고, 상공업학교에서는 시민교육-사실주의-시민 양성을 동시에 독립적으로 운영하는 체제로 정착된다. 특히 김나지움은 1835년부터 순수한 신인문주의를 벗어나 자연사와 같은 실물교과를 도입함으로써 양형주의를 선택하게 되었다. 이로써 칸톤학교는 참다운 인간성 교육, 철저한 학문적 교육, 생활 속에서 시민적 삶의 능력을 추구하는 학교가 되었으며, 아인슈타인은 여기서 진정한 민주주의가 실현되고 자신에게 잊을 수 없는 인상은 남긴 교육기관의 모범을 찾게 된다.

This study attempts to examine the regional distribution and the locational pattern of leisure facilities at Kangnam-gu in Seoul. For the convenience of the analysis the facilities are classified into public and private sector and then the facilities are classified into 11 types: mineral spring resort, play ground, neighborhood park, swimming pool, gymnasium, bowling, pingpong, aerobic, golf practice, health, and billiard facilities. For the purpose data was collected from statistical yearbook in 1993 and lists of registered facility at department of living physics of Kangnam-gu office. The data of the density of facilities and the opportunity of facilities per facilities type and per region are analysed with the technology of GIS. Results may be summarized as follows. First of all, correlation between the results of Location-Allocation model and the results of Interaction model is very high. Secondly, on comparing the density of facilities with the opportunity of the facility use per eleven facility types, three discrete spatial pattems are found. The mineral spring resort facility type with the highest unbalanced density and opportunity of facility use is to be found. Play ground, neighborhood park, swimming pool, gymnasium, bowling, pingpong, and aerobic facility types have the high unbalanced density and opportunity of facility use. The golf practice, health, and billiard facility types have spatially balanced density and opportunity of facility use. Thirdly, as comparing the density and the opportunity of the facility use per 'dong' administration unit, the spatial patterns of the public and the private facilities are different in density of the facility use and otherwise two are similar in the opportunity of the facility use. Fourthly, patterns of facilities users have different charateristics based on facility use time, expense, residence, and access time and four regional patterns are to be found ; user favorable, facility profitable, user balanced, and unfavorable.

In statutes on the promotion of distribution of new and renewable energy, which were revised in 2014, daylight system and fuel cell were added in addition to existing new and renewable energy sources. This study, therefore, aimed at setting up targets for the introduction of daylight system and analyzing the installation rate of new and renewable energy which can be provided by daylight system for the aggressive use of daylight system, thereby deducting the optimal combination ratio with other new and renewable energy sources. The results of the study are as follows. First, when a prism-shaped daylight system was installed to a round indoor gymnasium among domestic indoor gymnasiums, out of a supply obligations allotment rate of 15% of new and renewable energy, the rate of daylight system was basically set at 2.5%. Second, therefore, with daylight system coming first, the lacked supply obligations rate was taken up by solar photovoltaic, solar heat and geothermal heat. In addition, using the KRESS Program, economic, technical, environmental and complexity evaluations for the upper 5% was made, deducting the optimal ratio of the system. The results produced the following optimal combination ratios: solar photovoltaic (83.3%) in economic evaluation, solar heat (8.3%) and geothermal heat (75%) in technical evaluation, solar photovoltaic (83.3%) in environmental evaluation, and solar photovoltaic (83.3%, the same as in economic evaluation) in complexity evaluation.
