Purpose: As the medical environment changes, the size of medical facilities continues to change. Of course, it is not easy to analyze the correlation between changes in the medical environment and changes in facility size in a rigorous scientific method. However, the results of investigating and analyzing changes in the size that occurred for any cause be able to serve as important references for future medical facility architectural plans. Methods: This study surveyed 68 general hospitals in Seoul for 15 years from 2005 to 2020. The change in the number of beds was investigated with data from the Ministry and Welfare. The gross area change was confirmed by analyzing the of all hospitals. Results & Implications: As a result of the survey, general hospitals in Seoul show a common phenomenon in which all hospitals except one case have expanded their size in the direction of increasing the gross area per bed over the past 15 years. However, in the method, a relatively small hospital with less than 500 beds mainly chose to reduce the number of beds. Large hospitals increased both the number of beds and the gross area, however showed a significant increase in the gross area.

최근에는 '빈집 및 소규모 주택정비에 관한 특례법'을 제정하여 정부정책사업으로 가로주택정비사업을 활성화하기 위해 노력하고 있다. 그라나 이 정책은 원도심의 노후 불량 건축물이 밀집한 가로구역에서 소규모 정비사업보다 대규모정비사업 이 더 적용돼서 실적이 매우 미흡하고 제도개선이 필요한 실정이다. 그래서 본 연구에서는 전문가 간담회와 설문조사를 통해 대규모 정비사업과 차별화된 법적인 공공지원 방안을 도출한다. 연구결과는 '층 면적 비율'과 '건축물의 높이제한 기준 완화'가 가장 효과적인 반면 '지자체에서 주민공동시설 유상매입 후 운영'은 미미한 것으로 나타났다. 이러한 결과는 그 지역의 사회환경을 파괴하지 않고 노후한 주택 지역을 정비사업을 하는 동시에 취약계층에 임대 주택을 제공함으로 공공기관에 큰 이익이 될 수 있다는 전망이다. 그리고 소규모 정비사업인 가로주택사업을 활성화하기 위해 효과적으로 도입하여 적용 가능한 특례항목을 제시함으로서, 도심지내 임대주택건설을 유도하고 세입자 우선공급을 통한 둥지내몰림 현상을 방지하며 신혼부부나 청년 등의 젊은 층 입주를 통해 노후주거지에 새로운 활력을 도모하는데 도움이 될 것으로 기대한다.

The purpose of this study was to estimate the resistance capacity of a traditional wooden house with shear walls made of wood panel. In order to achieve the purpose of the study, the load - displacement test was carried out and the resistance moment values of the shear walls were proposed. The shear walls were made by placing studs with a nominal dimension of $38mm{\times}89mm$ at intervals of 600 mm, and attaching 12 mm thick plywood with 8-d size pegs at intervals of 150 mm. The type of traditional building wall was classified and showed the moment resistance ability of each wall type. This value is expressed as a proportional value divided by the moment resisting capacity of the standard size shear walls not divided into the divided small frames. Although some frames have proportional values larger than 1.0 even though they have openings, most of them show values smaller than 1.0. Also, even without the openings, it showed a smaller value than 1, such as 0.84 and 0.67.

최근 대도시 주변 중심으로 새로운 택지지구를 개발하거나, 오래전에 개발된 주거지를 새로운 택지로 재개발하는 사업들이 활발하게 진행되고 있다. 이러한 택지지구의 대지에는 건축주가 직접 건물을 지을 수 있는데, 건축주가 직접 집을 짓는 방식을 건축주 직영공사라고 한다. 건축주 직영공사에서 건축주가 건설사업관리(Construction Management, CM) 능력을 보유하고 있다면, 직영공사를 CM방식으로 수행할 수 있는데, 이러한 공사수행방식을 건축주(Owner)-CM방식이라 한다. 그러나 국내에서 소규모 건축공사의 수행방식이 건축주-CM방식인 경우는 매우 드물다. 이는 건축주가 CM에 대한 지식과 경험이 부족하기 때문일 것이다. 본 연구에서는 수도권 인근에 개발된 단독주택단지내에 거의 동일한 시기에 직영공사로 지어진 유사한 규모의 상가주택들을 대상으로 공정관리 실제 사례를 조사하였다. 그리고 본 연구는 건축주-CM방식으로 수행된 소규모 건축공사의 공정관리 사례로부터 소규모 건축공사에서의 공정관리 성공요인들을 도출하는 것을 목적으로 하고 있다. 이러한 공정관리 성공요인들은 향후 자신의 집을 직접 짓고자 하는 건축주들에게 의미 있는 참고자료로 활용될 수 있을 것이다.

Special attention is required for the design of windows due to their high thermal vulnerability. This paper examines the problems that might arise in the application of the u-value, by reflecting the changes in the u-value of the window, depending on the window-to-wall ratio obtained in an energy demand analysis. Research indicates that the u-value of a window increases with an increase in the difference between the u-values of the frames and the glass. Relative to the changes in the u-value of the windows, the energy demand varied from 1.3% to 9.3%. Windows with a g-value of 0.3 or 0.5 displayed a higher energy demand than windows with a g-value of 0.7. Therefore, when the difference between the performance of the glass and the frame is significant, especially when the g-value is small, a modified heat transmission coefficient should be applied to the window size during the evaluation of the building energy demand.

Nowadays, as the development period of new products becomes shorter and consumer's requirement is more various, the importance of Rapid Prototyping Technology has been rapidly increased. Rapid Prototyping makes prototypes or frictional parts directly using the 3D CAD data. But RP machines can make prototypes in limit size. For making large size prototype, we slice solid which is made of STL file, and then glue sliced solid. And if contact area of part is small, union solid will be easily destroyed for going down of adhesion. So we need to expand contact area, 1 suggest making a section into stair shape. This paper is concerned with slicing solid on STL file and improving on adhesion.

The mold transformers have been widely used in underground substations in large building and have some advantages in comparison to oil-transformer, that is low fire risk, excellent environmental compatibility, compact size and high reliability. In addition, the application of mold transformer for outdoor is possible due to development of epoxy resin. The mold transformer generally has cooling duct between low voltage coil and high voltage coil. A mold transformer made by one body molding method has been developed for small size and low loss, but it needs some cooling method because heat radiation between each winding is difficult. In this paper, the temperature distribution and thermal stress analysis of H class 100kVA pole cast resin transformer for power distribution are investigated by FEM program.

The paper aims at analyzing the stress distribution around an underground opening that is subjected to non-symmetrical surface loading with emphasis on opening shapes with sharp corners and the stress concentrations developed at these locations. The analysis is performed utilizing the BIE method coupled with the Neumann's series. In order to implement this approach, the special recurrent relations for half plane were proven and the modified Shanks transform was incorporated to accelerate the series convergence. To demonstrate the capability of the developed approach, a horseshoe shape opening with sharp corners was investigated and the location and magnitude of the maximum hoop stress was calculated. The dependence of the maximum hoop stress location on the parameters of the surface loading (degree of asymmetry, size of loaded area) and of the opening (the opening height) was studied. It was found that the absolute magnitude of the maximum hoop stress (for all possible surface loading locations) is developed at the roof points when the opening height/width ratio is relatively large or when the pressure loading area is relatively narrow (compared to the roof arch radius), and contrarily, when the opening height/width ratio is relatively small or when the surface pressure is applied to a relatively wide area, the absolute magnitude of the maximum hoop stress is developed at the bottom sharp corner points.
