본 논문은 알미르 슈타트 극장 이후에 나타나기 시작하는 공간의 비위계적 구성(non-hierachical arrangement)으로 평면계획이 이루어진 SANAA의 작품들을 선정하여 공간구문론(space syntax)에 의한 정량적 분석을 시도하였고, 외형적으로 보여지는 평면구성의 비위계성이 정량적 수치값으로는 어떻게 나타나는지를 분석하였다. 분석결과 다음과 같은 결론을 얻었다. 첫째, 외형상 보여지는 비위계적 평면구성을 보이는 SANAA의 각 공간들은 정량적 수치값의 분명한 차이를 보이고 있으며, 외형적으로는 잘 드러나지 않는 공간의 위계 차이가 분명히 있음을 확인할 수 있다. 둘째, 통합도(Integration)값이 높은 공간들은 연결도(Connectivity)값도 대부분 함께 높음을 알 수 있었는데, 비위계적 평면구성의 위계성을 부여하는 방법으로 공간의 출입구 개수를 늘리거나, 실의 크기와 위치조정을 통해 숨겨진 위계성을 부여하고 있음을 알 수 있다. 셋째, SANAA는 그리드 형태의 평면구성에서 내부 복도 대신에 외곽부 복도를 이용하여 접근성 문제의 해결을 시도하고 있으며, 방과 방 사이의 오픈 코트 공간은 자연채광과 환기를 제공함과 동시에 공간의 숨겨진 위계성을 조절하는 장치로 채택되고 있음을 알 수 있다.

The purpose of this study is to classify the building layout and plan types according to the urban location, use and function of civil and to analyze the characteristics by the type classified. After constructing a framework (Mathia type, Nagaya type, Detached House type) for analyzing Modern Private Housing Architecture in Gunsan, the research was conducted on 30 representative buildings, and a plot plan, a floor plan and elevation were created. After analyzing the relationship between the lot of land and the urban street, we classified the type of arrangement into Mathia type and Nagaya type which directly enter the building from the road, and derived the Detached House type which indirectly enters from the road. When we look at the use of the derived arrangement types, most of the Mathia type are commercial and residential buildings, and some of them are specially designed for commercial buildings. The Nagaya type appears in the form of commercial and residential house or residential private house, and the Detached House type is classified as residential style. As a relation with the urban street, the Mathia type and the Nagaya type are generally located on the main urban street, whereas the Detached House type is located on the small urban street. As a result of analyzing, the floor plan was changed according to the plot plan. The plan of the Mathia and Nagaya type are arranged to enter directly from the street, with commercial space being mainly located on the street, and the residential space being composed on the back or the second floor. the plan of the Detached House is a type that enters indirectly into the interior through a separate space (Courtyard), and forms an organic space between the residential interior and the front and rear yard. The purpose of this study is to investigate the Characteristics of a plot plan and a floor plan of Modern Private Housing Architecture in Gunsan by means of analysis considering the urban street, Uses of buildings, Construction method and the yard through actual measurement.

This study aims to classify the framework and arrangement of interior columns (Naeju) which are used in single-story Buddhist halls into several types, and to develop a theory on the process of changes among those types. Since interior columns are building materials which hold up the roof structure and make partitions in the interior space of halls, their framework and arrangement is closely linked to the development of building technology and is expected to reflect new architectural needs. The kinds of interior columns classified by the shape of framework are goju, chaduju, oepyonju, naepyonju. The arrangement of interior columns can he classified by two methods: One which counts the number of the interior column arrangements in a hall, and the other whose classification relates with the side wall columns - Jeongchibup and yijubup. With the combination of these classifications, we can divide the framework and arrangement of interior columns into 8 types From the remains of Korean and Chinese Architecture, we can presume that before the late-Goryo period, jeongchibup had always been applied in the construction of Buddhist halls, and gamju(column reducing) had only been used in examples of small scale. After the founding of Choseon Kingdom, however, national policy had weakened the economic power of Buddhist temples. Because of that, large-scale outdoor Buddhist mass was replaced by small-scale indoor mass, and for this reason, though the scale of Buddhist halls became smaller, the need for a broad interior space became stronger. Thus in early-Choseon period, reduction of interior columns became widely spread. Those types of framework and arrangement of interior columns where yijubup was applied were developed because the rear interior columns arrangements, in order to expand the interior space, have moved backward. Among these types, yiju-goju and yiju-chaduju were developed for the Buddhist halls with paljak roof(hipped-gabled roof), where the load of their side eaves caused structural problems at the side walls. And oepyonju type was for the small-scale and middle-scale Buddhist halls which needed more interior space but didn't want the extension of roof structure. From the local and periodic distribution of each types, we can conclude that the types jeongchi-goju, jeongchi-chaduju and yiju-chaduju have been settled as typical technique of local carpenters. Oepyonju was developed later than the other types, but for its merit of low cost, it became a popular type across the nation.

본 연구는 동궐도에 나타난 괴석의 배치를 바탕으로 조선시대 궁궐에 쓰인 괴석의 배석형식과 활용을 고찰한 것이다. 동궐도에서 축선을 보조하여 정형성을 형성하는 괴석 배열의 종류는 단식, 대식, 연식으로 구분된다. 단식은 기존 건축물을 통해 형성된 축선상에 괴석 1개를 배치하여 시각적 초점을 부여하거나 중심성을 강조하기 위해 사용되었다. 대식의 경우, 주로 건물 양옆에 괴석 2개를 대칭구도로 놓아 건축물에 질서와 위계를 부여하기 위해 사용되었다. 또한 세 개의 돌을 나열한 연식은 주석(主石)의 역할을 하는 가운데 돌이 축선 상에 놓여 강한 방향성과 정면성을 부여하는 방법으로 사용된다. 이러한 괴석 배치법은 수목의 배식에도 동일하게 적용되는 것으로, 수목의 요점식재와 대칭식재 방법에서 유사성이 발견되었다. 따라서 괴석과 수목은 장소의 성격과 규모에 따라 취사선택될 수 있으며, 축 형성과 정형적 공간창출의 효과는 근본적으로 같다고 할 수 있다. 이상의 결과를 바탕으로 동궐도 괴석의 배치 특성을 고찰한 결과는 다음과 같다. 첫째, 괴석은 중요한 건물에 위계를 표현하기 위해 설치되어 구심적인 공간을 창출하는 수단으로 사용되었다. 둘째, 괴석간 거리는 가운데에 있는 건축물의 크기에 비례하여 조정되었으며, 이는 중심축과 좌우 대칭물 간의 비례적 균형구도를 통해 안정감을 부여하기 위함이었다. 셋째, 불규칙한 괴석의 외형이 규칙적인 대칭성을 형성하는데 제한요소가 되므로 석함을 활용하여 정형성을 더하였다. 넷째, 연식(3입식) 배치에서 가운데 괴석에 변화를 주어 중심성을 강조하였다. 다섯째, 괴석은 타 점경물의 종류와 배합 및 위치조정이 수월하도록 크기를 제한함으로써 얻어지는 이동성이 있었다. 여섯째, 사의적 대상으로 감상되던 궁궐 괴석은 근본적으로 수석과 동질적인 개념의 조형물 이었으며 감상되는 방법, 형태, 구성에서 같은 맥락으로 전개되었다. 일곱째, 연식으로 놓인 괴석은 짝수일 경우 균등분할 식으로 배치되며, 홀수일 경우 중심 괴석을 중심으로 나머지가 대칭하도록 배열하는 방법을 따랐다. 이상의 배석원칙은 조선 궁궐에서 괴석을 제작하고 활용했던 특징적인 방법으로 판단된다.

The purpose of this study is to investigate types and formative characteristics of 'Seon' represented of costume in Amitabha of the late Koryo Dynasty. The results were as follows; The type of 'Seon' is classified into Standard, Decoration and Application types. According to three types, the types of the standard are subdivided into same rotor and no pattern and different color and no pattern, the types of the decoration are subdivided into same color and pattern and different color and pattern, And the types of the application are subdivided into wrinkle and beads-decorated wrinkle according to whether decorative beads exist or not. In the Standard type of Seon, same color and no pattern in the Decoration type of Seon, different color and pattern was most often used as its type while, in the applied type of Seon had its main type of beads-decorated wrinkle. Patterns used for Seon were complex in its composition type and filing in its arrangement style. Seon was used mainly for guneui(裙衣) and daeeui(大衣). The color arrangement of Seon, in most cases, used complementary colors, followed by same ones. Regarding costumes aesthetic characteristics in accordance with the type of Seon, those costumes appeared natural and plain when their Seon was same color and no pattern in type, artificial and plain when their Seon was different color and no pattern in type, natural and brilliant when same color and pattern in type and artificial and brilliant when different color and pattern. In regard to the applied type of Seon, such costumes looked sophisticated and delicate when their Seon was wrinkle in type and dynamic and decorative when beads-decorated wrinkle.

Consider a job shop that is modelled as an open queueing network of the Jackson(l957) type. All work stations in the shop have the same number of parallel servers. Two problems are studied : the loading of stations and the assignment of servers, which are represented by loading and assingment vectors, respectively. Ma jorization and arrangement orderings are established to order, respectively, the loading and the assignment vectors. It is shown that reducing the loading vector under ma jorizat ion or increasing the assignment vector under arrangement ordering will reduce the congestion in the shop in terms of reducing the total number of jobs(in the sense of likelihood ratio ordering), the maximum queue length(in the sense of stochastic ordering), and the queue-length vector( in the sense of stochastic majorization). The results can be used to supprot production planning in certain job shops, and to aid the desing of storage capacity.

PV/Thermal module is the combined system, which consist of a photovoltaic module and solar thermal collector that can obtain electrical power and thermal energy simultaneously. Thus the power generation can be increase by decreasing the temperature of photovoltaic module and thermal energy retrieved from module also can be used for heating system. In this study, Heat transfer performance of air type PV/Thermal module was confirmed with various bottom obstacles that can be installed easily to real photovoltaic module by CFD (computational fluid dynamics) analysis. Eight type obstacles were investigated according to the shape and arrangement. As a result, nusselt number represent heat transfer performance was increased about 86% compare with the basic type PV/Tthermal module that has no obstacle and triangle type obstacle had higher value than other types. But pressure drop was also increased with increment of heat transfer enhancement. Thus the performance factor considering both heat transfer and pressure drop was confirmed and V-fin type obstacle arranged in a row for Reynolds number below 9,600 and protrusion type obstacle arranged in zigzag for Reynolds number above 14,400 were shown higher performance factor than other types. From these results, V-fin type obstacle arranged in row and protrusion type obstacle arranged in zigzag were considered as a proper type for applying to real PV/thermal module according to operating condition. But the heat transfer performance can be changed by the geometric conditions of obstacle such as height, width, length and arrangement. Thus, it could also confirmed that the optimal condition and arrangement of this obstacle need to be found in further study.
