This study is aimed at analyzing on the sunshine according to the blocks direction by location type of apartment complex in Busan, to propose a planning on the decision of blocks direction and the improvement of architectural law in sunshine environment. The results of this study were as follows; On the basis of winter solstice in "□ block type", the average of ratio of shadow area in flat site is 51 % in apartment with a southern exposure, 39% in apartment with a south-eastern exposure. The average of ratio of shadow area in the descended site toward the north is 49% in apartment with a southern exposure, 34% in apartment with a south-eastern exposure. The average of ratio of shadow area in the descended site toward the south is 66% in apartment with a southern exposure, 53% in apartment with a south-eastern exposure.

Seasonal climatic factors associated with tobacco quality grade and production rate were analyzed. The degree of influence on yield distribution rate in high guality tobacco leaues was highly positive with the average temperature in early May, but negatively related to those in late May and early June. Positive correlations were noticed between the degree of influence and sunshine hours in Middle June, late June and late May in decrease order, while negative degree of influence was higher in early May than in late May, The order influenced by recipitation in a positive direction was early May, late May and middle May. Negative influence was noticed in middle and early June with a great degree.

A building's eco-friendliness is directly related to various values including the life cycle cost of a building. However, the conventional architectural design method has a limitation in that it cannot create an optimized case according to the surrounding environmental conditions. Therefore, the purpose of this research is to present a design assistance tool that can review planning cases optimized for the environmental conditions of the building site in the planning stage of architectural production. To achieve the purpose of the study, an algorithm for realizing 3D modeling of the region and analysis of the solar environment was produced based on the site contours, building, and road information from the digital topographic map provided by the National Geographic Information Institute. To examine the validity of the developed algorithm, a comparative experiment was conducted targeting the elevation direction of the existing building. As a result, it was found that the optimal elevation direction selected by the algorithm can receive higher insolation compared to the front facade of the main building.

The aim of this study was to analyse the design characteristics of court housing. In spite of changes of housing design condition, especially density, there have been changes only in the height of housing block, not in the housing types, layout system and other design properties. Due to the situation, housing design in Korea has been criticised as too routine and monotonous one. As one of the alternatives to respond to the criticism, this study focused on the positive aspects of the court housing type, and suggested the design strategies throughout the analysis of 8 entries in the design competition of EunPyeong NewTown, which attempted to overcome the negative problems - mainly the daylighting, orientation, and privacy- of this housing type. Throughout the analysis, there suggested design strategies to respond to the problems of court housing type, which can be the basis for the court housing design in Korea.

In flue-cured tobacco, the relationships between the quality of tobacco leaves (productivity according to quality grade) and specific meteorological factors were noted showing different significances according to different seasons during the growing period of the tobacco plants. The thick leaf high quality was significantly correlated with average temperature in late April, late May, early July and late July. The degree of contribution was greatest in middle May and lowest in late May. In the highest and lowest temperatures, the relations to leaf quality had similar tendency like in the average temperature; the thick leaf low quality showed opposite tendency relative to the high quality in the degrees of correlations and contributions. Amount of precipitation was significantly correlated with the thick leaf high quality in late April, early May, middle May, late June and late July. The degree of positive contribution was shown in order of late April, middle July and early July, and that of negative one was in order of middle June, early June and late June, respectively. Duration of sunshine period was highly associated with thick leaf high quality of tobacco leaves in all of the growing season except for middle April and middle July. The degree of positive contribution was in order of late May, late April, early July and middle July, and that of the negative one was in order of late June, early May, middle June and middle May.

This study was to figure out the design characteristics of court housing type for the purpose of searching for the possibility of applying it to the housing design in Korea. In spite of changes of housing design condition in Korea, especially steep increase in density, there have been changes only in the height of housing block, not in the housing types, layout, spatial organization and other design properties. Due to such a situation, housing in Korea has been criticised as too high, monotonous one - especially types of housing block tend to be fixed into a slab block and a point block. As one of the alternatives to respond to the criticism, this study focused on the positive aspects of the court housing type, and suggested the design direction throughout the analysis of 8 entries in the design competition of EunPyeong New Town, which attempted to overcome the negative problems - mainly the daylighting, orientation, and privacy - and tried to maximize the positive properties of this type of housing.

The purpose of this study aims to provide possible suggestions for the improvement KDC 5th ed. as a system. After analyzing and evaluating various devices of KDC 5th ed. such as schedules, common auxiliary tables, internal tables(omitted), notes, relative index, precedence order(omitted), alternatives, manual(omitted) and relocated table(omitted), suggestions for the improvement were proposed. If above suggestions are adopted, effective literature classification scheme which is suited to domestic circumstances will be certainly prepared.

Apartments with a southern exposure are often thought to have advantages in receiving winter sunlights and summer natural ventilation. However, as due-south-apartments increase recently, the consideration for residential environment for households with no southern exposure is necessary. In case of due-south-apartments, residents prefer east-sided apartments than west facing apartments which might receive more hot sunlight in the afternoon; however in case of west-oriented apartments with active ventilation, the interior area is bright until late afternoon without unpleasant heat and has advantage in light environment aspects. This study aims to compare and analyze merits and demerits of air flow and sunlighted environment of buildings through sunshine duration simulation using CFD simulation ad sunlights about southeast-sided and southwest-sided apartments based on general opinions for apartment directions. As results of the interior natural ventilation analysis, as the average air flow speed in southwest-sided apartments was 1m/s faster than that of southeast-sided, it has effects of lowering sensory temperature of residents in summer, and for sunlighted environment, southwest-sided apartments are advantageous for sunlighted area for duration time inside. As a result of the research, the calculation of physical residential environment of apartment residential space should be reached through integrated evaluation of natural ventilation and sunlighted time from placement and facing direction of the buildings considering characteristics and environment of each apartment, not based on general opinions.

급격한 도시화와 기후변화로 인한 자연적인 물순환 구조의 변화는 기존 수자원 이용 경향을 변화시키며 하천건천화 현상을 유발하고 있다. 이를 관리하기 위해 하천건천화 평가 및 예측이 가능한 영향 평가 기술이 필요하며, 국내에서는 GIS 기반의 분포형 수문 모형인 Drying Stream Assessment Tool and Water Flow Tracking (DrySAT-WFT)이 개발되어 활용되고 있다. 그러나 격자기반의 물수지 모형은 단위 cell 안의 수직적인 물의 거동은 파악하기 용이하나, 모형의 특성상 저수지, 댐, 보와 같은 수리 시설물의 방류량에 따른 하도의 흐름 추적에는 어려움이 있다. 본 연구의 목적은 DrySAT-WFT 모형에 댐?보 방류량 자료와 연계한 하도추적 알고리즘을 개발하여 모형의 유출 모의 성능을 개선하고, 1976년부터 2015년까지의 유출 모의를 통해 전국 표준유역을 대상으로 각 유역에 대한 하천건천화 원인 추적 및 평가를 수행하고자 한다. 하천건천화영향요소를 고려하기 위한 모형의 입력 자료로 산림높이, 도로망, 지하수 이용량, 토지이용, 토심, 기상 변화에 대해 1976년부터 2015년까지 구축한 시계열 전국 자료를 활용하였으며, 일별 강우량, 상대습도, 평균풍속, 평균 및 최고, 최저 기온, 일조시간의 기상자료를 구축하였다. 개선된 DrySAT-WFT 유출 모의 결과는 선행 연구와의 비교를 통해 모의 개선점을 정량적으로 제시하고자 한다.
