In commercial areas, outdoor units are typically installed close to one another in the narrow space between buildings due to insufficient regulations. This makes it difficult to ventilate the discharge airflow, which may lead to deterioration of the performance of outdoor units. This study conducted CFD simulation to analyze the thermal environment according to the installation distance of the outdoor unit. The outdoor unit was installed in the space between buildings, and the thermal environment was analyzed by changing installation distance and wind speed. The performance of the outdoor unit was evaluated by measuring the on-coil temperature. The results show that the closer the distance between outdoor units, the higher the condenser on-coil temperature. Also, the on-coil temperature appeared to rise dramatically at lower wind speed.

Fen(分°) is the proportional dimension unit of the standard timber section on Yingzaofashi(營造法式), and there is a phrase that not only structural members but the whole structural design of a building also use Fen as the dimension unit on the book. But in fact only the section dimensions of structural members are recorded by Fen, but the design dimensions are recorded by Chi(尺) on the book. Other historical records also described the building size by Chi. So there has been long-standing debate on the phase in Chinese architectural history society, including the recent confrontation on the analysis of survey figures of the east great hall of Foguangsi temple(佛光寺 東大殿). This paper analyzes all the records about the size of structural members and section planning on the book to make various calculation and evaluation. And it makes a survey of Cai(材) as the dimension and design unit between Chi and Fen through geometric analysis. Cai might be a rough unit of measurement in terms of structural and proportional scheming on Yingzaofashi, and the full size Cai(足材) had been a building scheming module before the Song dynasty.

A ground source heat pump (GSHP) system can stable system operation by using underground heat source and has high reliability for energy production. However, wide-spread of the GSHP system is delayed to high initial investment costs. In previous studies, horizontal and unit-type ground heat exchanger (GHX) have developed to overcome disadvantages such as high initial cost. However, these performances of GHXs are greatly influenced by climate and weather conditions. It is necessary to analyze the performance of GHX according to the ground temperature change in the installation site. In this study, the ground temperature of each installation site confirmed and performance of unit-type GHX quantitatively analyzed by numerical analysis. As the result, the performance of the unit type GHX was 33.9 W/m in Seoul, 34.2 W/m in Daejeon, and 37.2 W/m in Busan.The result showed the difference performance of GHX according to local climate was maximum of 9.7%.

The subjects of this study were limited to Silla buddhist temple remains in the 6~8th century, where the excavation survey report was published and the details of the remains of the corridor are revealed. Since the corridor completes the structure of temple and is involved in formation of the space, the building plan for corridors is thought to have an intention linked to the entire temple. Thus, more closer study is required for this construction plan to identify the role of corridors. The corridor is a building that has a low architectural hierarchy and completes the layout and composition of the temple. In the unit planning of the corridor, unit were designed to be of a certain size in the temple layout. Then, the overall scale was made by adding the fixed size of unit. The combination of corridors are the combined points of paths and were used as visual points. The structure of the corridor was constructed to be adjusted according to the size of the main compartment of the building to which it was connected and inserted under the roof of the building. The adjustment of the unit changed in the range of 0.5 to 2 of Silla's system of measurement. The usage of embedded pillar in the corridor presents a new perspective on Silla architecture.

유닛 모듈러 공법은 공장생산에 의한 공기단축, 품질관리, 친환경성 등 기존공법과 다른 다양한 특징을 가지고 있다. 이러한 특징에도 불구하고 현재 국내에서는 군 병영시설, 학교, 소형주택에만 제한적으로 적용되고 있다. 본 연구에서는 모듈러 공법의 시장 확대 및 활성화를 위해 공동주택을 중심으로 특성요인들에 대한 중요도 및 기술수준을 IPA 기법을 통해 분석하여, 모듈러 시장의 활성화 방안을 제시하였다. 분석결과 유닛 모듈러 공법을 공동주택 시장에 적용함에 있어 사용성 및 경제성 측면의 특성요인들이 중요하게 평가되었으나, 현재 기술수준은 상대적으로 중요도가 낮은 시공성 측면의 특성요인들이 높게 나타났다. 유닛 모듈러 공법을 공동주택 시장에 적용하기 위해서는 시공성 측면의 높은 기술수준을 바탕으로 사용성, 경제성 측면의 특성요인에 대한 보다 집중적인 연구 개발이 필요할 것이다.

At the economical crisis of Korea in 1997, self-determined price for apartment and the revision increasing the ratio of residential area for mixed-use residential building were introduced to activate the construction industry, which causes construction companies to build super high rise apartment discriminative and high class orientated. This study aims to classify the super high rise building which is planned to build or built recently and to analyze the architectural characteristics. The objects are 288 unit households in 26 apartment complexes higher than twenty five story since 1998. As a result, super high rise building comparing with existing apartments were being varied in plan types of main building and unit household and in construction types. As for the plan, the number of walls having opening to outdoor were increased and it is considered that high rise building can take advantage of a view, lighting and sunshine. The location of living room that used to be in the center of unit in existing apartment was moved freely without rule.

The purpose of this study was to understand the timing of Gentrification by the study through the analysis of licensing data for food service businesses under the correlation with regional policies and systems. In addition, by analyzing the change in location patterns of the food service business in the district unit plan zones, the cause, development patterns and regional differences were identified. Starting with the Seoul hanok declaration in 2008, the approval of the food service business began to increase, and the floating population increased with the restoration of the Suseong Valley in 2012, and the concentration of food service business increased significantly on the waterway (Jahamun-ro 7-gil). Since the designation of Ikseon-dong as an urban environment readjustment zone in 2004, the approval of new food service business has been very low until around 2014, when the cooperative establishment committee is dissolved, and as the district unit plan for the preservation of hanok and regional management is being established, the number of new permits has exploded to date and restaurants in hanok conservation zones has been active.

최근 인력자원 투입량 감소 및 공기단축이 가능한 모듈러 건축공법은 반복 공정이 많은 기숙사, 주거시설, 호텔 공사 등에 다양하게 적용되고 있다. 모듈러 건축공법은 유닛 설치비용을 제외한 현장 공사비에서 외장 마감공사 비용의 비중은 약 40%를 차지하며, 마감공사는 목표공기와 비용을 유지하는데 주요한 역할을 한다. 모듈러 현장에서 유닛 설치 및 마감공사 수행을 위해 한정된 장비가 후속 액티비티에 영향을 주지 않도록 공유되어야 하며 현장 마감 비중이 커지는 모듈러 프로젝트일수록 공정관리에서 양중 계획은 매우 중요하기 때문이다. 이와 같은 T/C 운용 계획은 단일 사이클 또는 다중 사이클의 형태를 가지게 되며 사이클 주기 조율은 장비효율을 높일 수 있다. 그러나 유닛 설치 및 마감공사를 지원하기 위한 T/C 운용 계획의 대안을 평가하는데 어려움이 있다. 따라서 본 연구는 모듈러 건축 현장에서 T/C 운용의 사이클 주기 설정에 따른 운용방식의 대안을 평가하기 위해 유닛 양중 시간 및 주기, 외장재 양중 시간, 마감 작업 소요시간을 변수화하여 T/C 가동시간과 공정에 주는 영향을 파악한다. 이러한 목적을 달성하기 위해 현장에서 이루어지는 작업 프로세스 분석을 바탕으로 작업 속도를 조절하여 T/C 효율을 증대시킬 수 있는 시뮬레이션 모델을 개발한다. 본 연구는 양중 사이클 개념을 적용한 자원 평준화 방법을 제시함으로써 학술적 기여가 있으며 실무적으로 현장관리자에게 장비 계획의 대안 선택을 위한 기초자료로서 활용될 수 있을 것이다.

Purpose: The Intensive Care Unit (ICU) is an important inpatient care area where critical patients are treated intensively with advanced medical technology. The level of care of ICU and the modernization of related facilities is an important indicator of health care quality. At the present time, when the Regional public hospitals are frequently expanding, the rational planning of the ICU has become an important part of the medical institutions treating the ICU. The purpose of this study is to present basic data with net area which can be used in the architectural planning of the ICU. Methods: The investigation and analysis of the ICUs were conducted on 26 medical facilities, based on theoretical analysis through relevant guidelines, articles, and documents, and on the basis of the actual space composition and net area analysis through the architectural drawings. Results: This study provides basic data such as zone division, spatial composition, relationship between main activities and zones, composition of facilities in the zone and area ratio within each zone. Implications: The results of this paper are expected to be effective reference materials for future research for rational spatial organization and efficient operation of the Intensive Care Unit in regional public hospitals.
