An attempt is made to illuminate the characteristics of Korean high-rise apartment plans built after the 1990s in Seoul. Unlike the typical slab block plans of the past century, these plans were accommodated in a super-highrise building which normally integrates some portion of commercial areas on the lower floors. Thus, they are much different from the pre-1990s plans, so needs to have different strategy to adapt to the Korean dwellers' domestic requirements. This study reveals the topological patterns that appear in these new plans, and tries to relate these patterns to the old configuration patterns of the slab-type apartment houses. From the analysis, it was found that some important Korean dwellers' characteristics are still preserved, but at the same time, some unprecedented patterns were beginning to be absorbed into the spatial arrangement. At the end, suggestions are made on how this emerging trend of super-high rise can be better understood and evolved to enhance the living quality in a new multi-unit setting.

Unnecessary transportation of resources are one of the major causes that adversely affect construction site work productivity. Therefore, layout related studies have been conducted with efforts to develop management technologies and techniques to minimize the resource transportation made at site-level. However, although the necessity for floor-level layout planning studies has been increasing as buildings have become larger and floors have become more complicated, studies to optimize the transportation of materials inside buildings are currently not being actively conducted. Therefore, in this study, a model was developed using genetic algorithms(GA) that will enable the optimization of the locations of finishing materials on the work-floor. With the established model, the arrangement of diverse materials on complicated floors can be planned and the optimized material layout planning derived from the model can minimize the total material transportation time spent by laborers during their working day. In addition, to calculate travel distances between work sites and materials realistically, the concept of actual travel distances was applied. To identify the applicability of the developed model and compare it with existing methodologies and analyze it, the model was applied to actual high-rise residential complexes.

In A bridge which connects Mokpo North Harbor and Com Island is going to be constructed until 2009. For the bridges being built in the navigable water area, it is indispensible to carry out vessel traffic safety assessment from the viewpoint of shiphandlers, however, there exist no specific guidelines for the necessary conditions whim the bridge designers can rely on. In this paper, traffic safety assessment procedures for the layout of the bridge is briefly introduced, and the conditions whim should be taken into account at the initial design stage of the bridge is surveyed. For the safety assessment of the bridge design, ship navigation simulations, such as RTS(real time simulation} and FTS(fast time simulation), are carried out, the results of which are statistically analysed to estimate the probability of collision between the ship and the pier of the bridge.

The purpose of this study is to analyze the various cinematic gaze and its realization through Seojong MA-Residence in Yangpyeong-gun, completed in 2016. This paper will focus on what kinds of cinematic concepts and design ideas were selected and considered in the stage of concept design, then how the site plan, floor plan, elevation and section design were developed in the stage of schematic design, and finally how much of the design intentions were successfully realized to the residential building. Architectural sketches, physical models and drawings at the concept & schematic design stage were reviewed. After the construction, some important issues were successfully realized such as interesting cinematic views to outside, visual openness and inflow of sunlight.

A hyperbolic numerical model with multi-directional waves has been used to investigate harbor tranquility in Pohang New Harbor. Comparing numerical results with field data measured at two stations in the harbor, it was found that use of input condition of multi-directional waves is superior to the use of uni-directional waves. Calculations with unidirectional wave input give errors of about 12% at St. P2 and 26% at St. P3, while calculations with multi-directional wave input give errors of 4 % at St. P2 and. 14% at St. P3. Using the input condition of multi-directional waves, we investigate the tranquility of Pohang New Harbor with two layouts : the condition in 1994 when the downtime at the 7th pier was often reported and the condition in 1996 when the 4th disposal site was constructed. The numerical results show that the problem of downtime at the 7th pier cannot be solved by the construction of the 4th disposal site.

우리나라 서해안 중부, 경기만 일대는 강한 조석과 잘 발달된 해만으로 인해 천혜의 조력자원 보고로 알려져 있으나, 1980년대부터 서 남해 연안역에 대한 대규모 매립과 항만개발 등으로 조력개발입지 자체가 상실되고, 조석체계도 변화되고 있다. 한편 조력에너지는 기존의 화석연료를 대체할 수 있는 개발가능한 신 재생 에너지 중에서 거의 유일하게 대규모로 개발이 가능한 것으로 평가되고 있어 개발시 기대효과는 매우 클 것이다. 이에 우리나라 서해안의 조력자원 부존량을 파악하고 주요 후보지에 대한 개발타당성 검토를 통하여 주요 조력자원 후보지를 타 개발로부터 보호하고, 민간참여를 유도하여 조력에너지 개발을 활성화하고자 본 조사를 추진하였다. 한반도 조력자원 개발타당성 검토를 위하여 1) 서해안의 주요 지점에 대한 조석특성을 조사하였고, 2) 주요 조력자원 후보지 위치 및 영역을 설정하였으며, 3) 조석체계변화예측 수치모형실험을 실시하였고, 4) 후보지별 발전소 평면배치계획을 수립하였으며, 5) 후보지별 연간발전량과 개략공사비를 산출하여 6) 후보지별 개략타당성 검토를 수행하였다. 검토결과 우리나라 서해안의 조력개발 가능규모는 215만kW 정도이며, 주요 후보지를 모두 개발할 경우 연간 3,826GWh의 전기를 생산할 수 있을 것으로 조사되었다. 또한 연간발전량 대비 순공사비 비율에 따르면 만 입구가 좁아 개발 경제성 확보가 유리한 가로림만을 우선 추진하고, 이후 인천만, 천수만 순으로 개발하는 것이 유리한 것으로 나타났다.

The origin of the Roman public basilica is Rome's indigenous style morphologically but actually it seems that developed the Greek semi-open style stoa into the Roman practical interior space. In the early ages, the arrangement of Roman forum had been planned high symbolical temple as the center but gradually changed into the basilica centered which were used often by citizen. Through the Roman period, the important types of early Roman basilica have Fano basilica in the first century BC, Pompei basilica of mid period in the first century AD, Doclear basilica with apse as late type in the second century AD. Pompei type well characterized the feature of Roman public basilica among them. The result of the floor plan analysis shows that the long side access to the interior space is over 76 percent of examples and nearly 70 percent have no apse and the average of vertical horizontal length ratio presents as 1:2.3. The typical plan of Roman public basilica can be defined that most of access are being entered from one of the long side, and most of basilica have no apse, and normally having inner columns arranged in one or more concentric rectangles around nave as a center.

목적 : 방사선 수술의 목적은 병소에 최대한의 방사선을 조사하고, 주위의 정상조직에는 가능한 적은 양의 방사선을 조사하는 것이다. 이러한 목적을 만족시키기 위해 방사선 수술계획자는 계획시 isocenter의 위치와 개수, 콜리메이터 크기를 변화시켜 가며, 주어진 병소에 맞는 선량분포를 획득해 방사선 수술효과를 최대화시키는 수술계획을 수립한다. 본 연구에서는 다양한 모양의 병소에 대해 자동적으로 isocenter를 위치시켜 수술 계획시 도움이 될 수 있도록 임의의 병소 모델들에 대해 위의 변수들을 변화시켜 가며 얻어지는 선량분포를 비교 분석하였다. 방법 : 본 연구에서는 임의로 정의한 계산 영역내에 다면체를 병소로 가정하여 연구를 수행하였다. 방사선 수술시 하나의 isocenter에서 얻어지는 선량분포는 구형으로 근사할 수 있으므로 하나의 isocenter를 구로 근사하여, 각 병소 모델 내에 콜리메이터 크기를 변화해가며 가능한 많은 영역을 포함하도록 isocenter를 배치시켰다. 이후 구형선량모델을 사용해 선량분포를 획득하여 병소와 정상조직간의 DVH(Dose Volume histogram)와 각 병소 모델에 대한 통일 평면상의 선량분포를 비교 분석하였다. 결과 ; 임의의 다양한 종양 모델에 대한 50%의 등선량 곡선내에서 세 가지의 빔관련 변수들을 변화시킨 결과, 종양이 없는 정상 조직에서는 선량분포가 극히 낮았으며, 콜리메이터의 크기에 따른 isocenter 의 개수가 변화하는 것을 확인할 수 있었고, 이 경우 한 종양모델에서의 깊이에 따른 선량 분포는 크게 차이가 나지 않았다. 그리고, isocenter의 개수가 변화함에 따라 선량곡선이 변하는 것을 확인할 수 있었다. 결론 : 빔관련 변수인 콜리메이터 크기, isocenter 개수, 거리등은 어느 일정 정도를 넘기면, 병소내 선량 분포에 크게 기여하지 않는다는 점을 감안하여 빔관련 변수들을 최소로 고려하므로써 계획시 소모되는 시간 과 노력을 많이 줄일 수 있을 것이며, 또한 각 병소 모델에 대한 최적의 구형선량모델에서 공통적인 규칙성을 찾는 것과 실제 병소의 모양을 간단한 모양으로 근사화 시킨다면 자동적 선량모델을 이루는데 많은 도움이 되고, 이로 인해 효율적인 치료계획작업이 이루어질 것이라 사료된다.

This study aims at analysing the daylight condition of the existing and the newly planned apartment complex due to the azimuth angle, and throughout that result, presenting the necessity of new concept of architectural law for apartment complex design in the matter of daylight condition. For this purpose selecting one apartment complex which showed typical shape of '=' or 'ㅁ', 3D daylight analysis was applied for the existing condition. And then after new complex was planned according to the architectural law, additional 3D analysis on the daylight with the various conditions were accomplished. This 3D analysis for daylight condition can give accurate results and design direction which are suitable for the new complex plan of apartment houses.
