Our final purpose may be to introduce generalized differential forms on the space Map(S, M) of mappings from a manifold S into a manifold M and discuss the differential geometry of the space Map(S, M) from the point of the generalized forms. Here we take a subspace X of the space Map(S,M) and we introduce the generalized differential forms on X, taking the dual to the chain space with the flat norm. This method of construction allows us to discuss a sufficient condition for a subspace Y of X to admit the generalized differential forms and the natural integration as the dual operation.

This study researched TV makeup types with a focus on Korean aesthetics. First, natural beauty is expressed with a random form that excluded artificial techniques or decorations often shown in the form of incompletion and space through TV entertainment programs. Incompletion is what excludes artificial technique and denies the whole completion in expressing a face, it shows the intentional incompletion that leaves it as a bare face that has no type, no color, and no decoration. A pursuit for purity, as nature leads to realizing the internal world of concentrating on the essence of object. Space is what makes it empty without filling, it offers a mental space in the inner side so that diverse images can be imagined beyond external form. This trend is indicated similarly to the tendency that the recent global interest in naturalism yearns for purity in nature and wellbeing. The presentation of skin (preferably healthy looking skin) is given attention; consequently, the similarity was being shown between the TV makeup that focuses on expressing skin and recent trends.

The turbulent natural convection in the membrane type LNG carrier cofferdam with heating points has been studied by numerical method. As the numerical methods, we introduced the three turbulence model, a standard $k-{\varepsilon}$ model and two case of a low Reynolds number models. The parameters considered for this study ore number and capacity of heating points i.e., $1{\leq}Ns{\leq}12$ and $1.0{\times}10^5{\leq}Qs(W/m^3){\leq}1.0{\times}10^8$. The results of the isotherms and velocity vectors have been represented for various parameters. The temperature and velocity at upper position in the space ore shown to be higher than those at lower position. For obtaining the optimal temperatures, $20{\sim}30^{\circ}C$ in the cofferdam space, the heating capacities show $2.0{\times}10^7W/m^3$ at g-heating points and $1.0{\times}10^7W/m^3$ at 12-points. The mean temperature in the cofferdam space can be expressed as a function of number and capacity of heating points.

The Miaos have their own unique and luxurious culture traditional and modern formed as they have experienced repeated fusion into and resistance against the Han Race or the Chinese in their long and old history. Taijiang County of Guizhou Provice, in which whey have been living, is endowed with natural beauty. Thus their culture enjoys abundant and diverse contents of artificial and natural character. Naturally, their costume reflects cultural and natural features in abundance and variety. This dissertation aims to investigate the artistic character of Miaos' traditional costume as reflected in patterns for their embroidery. As for the artistic character of the patterns for embroidery, the following were found. To begin with, the space in the Miaos' embroidery is, unlike the measurable three-dimensional space found in Greek art, unmeasurable and fantastic with its beauty, majesty and peculiarity. It is as if immersed in limitless space, they were in communion with gods and universe. Another characteristic is the use of image construction beyond mere imitation. Their mode of image construction was realistic in that patterns as a whole reveal an abstract form or meaning but separately they portray visual representations of concrete thins in nature. Still another is that sense of motion conveyed by the basic curve line is full of life. It was the result of using light rhythm breaking stereotypic balance and symmetry. Finally, the colouring was abstract, and a strong contrast between black and white was gorgeous and fantastic.

Raymond, who adopted Le Corbusier's Errazuris House Project, built Karuizawa Villa by incorporating Japan's aspiration for Western modern architecture and strong convictions regarding the preservation of traditional culture heritage, which were prevalent in Japan at the time. Despite the controversy over his plagiarism, Karuizawa Villa shows several unique architectural characteristics. First, in terms of the arrangement and access system, the villa has a common space that affords a view of the lake by accessing from the mountain side. Second, in terms of spatial composition, the common space is connected to the mesonnette by placing a trail to enable enjoyment of natural scenery. In particular, personal space is planned in the shape of a cross by connecting several surfaces to the outside in order to secure enjoyment of the natural environment. Lastly, in the aspect of structure and materials, both architectural buildings adopted masonry by using natural stone as well as building materials suitable for each region and climate by using logs in constructing the main columns and beams. Through Karuizawa Villa, Raymond is considered to have established his own style by combining the standard of Western modern architecture and the elements of Japanese traditional architecture while valuing local architectural technology.

The objective of this research is to assess the seismic performance of different types of electrical cabinets in nuclear power plants. The cabinets under investigation are: (a) Case 1: a short single cabinet; (b) Case 2: a tall single cabinet; (c) Case 3: separated cabinets; and (d) Case 4: a combined cabinet with coupling effects. To accurately capture the real behavior of the cabinet, three-dimensional finite element models are developed using ANSYS with connection non-linearity. Frequency domain decomposition (FDD) is used to determine the dynamic properties of the cabinets from shaking table testing data, and these results are utilized to validate the numerical model. The close match between the experimental and numerical results obtained from the modal analysis demonstrates the accuracy of the numerical model. Subsequently, transient structural analysis is performed on the validated models to explore seismic performance. The results show that the acceleration response of the combined cabinet is lower than the single cabinet and the separated cabinet. This observation suggests that top anchors used to combine two different types of cabinets play a crucial role in assessing the efficiency and seismic resistance of electrical cabinets in a nuclear power plant.

We develop a new auto-guiding system for the Camera for QUasars in the EArly uNiverse (CQUEAN). CQUEAN is an optical CCD camera system attached to the 2.1-m Otto-Struve Telescope (OST) at McDonald Observatory, USA. The new auto-guiding system differs from the original one in the following: instead of the cassegrain focus of the OST, it is attached to the finder scope; it has its own filter system for observation of bright targets; and it is controlled with the CQUEAN Auto-guiding Package, a newly developed auto-guiding program. Finder scope commands a very wide field of view at the expense of poorer light gathering power than that of the OST. Based on the star count data and the limiting magnitude of the system, we estimate there are more than 5.9 observable stars with a single FOV using the new auto-guiding CCD camera. An adapter is made to attach the system to the finder scope. The new auto-guiding system successfully guided the OST to obtain science data with CQUEAN during the test run in 2014 February. The FWHM and ellipticity distributions of stellar profiles on CQUEAN, images guided with the new auto-guiding system, indicate similar guiding capabilities with the original auto-guiding system but with slightly poorer guiding performance at longer exposures, as indicated by the position angle distribution. We conclude that the new auto-guiding system has overall similar guiding performance to the original system. The new auto-guiding system will be used for the second generation CQUEAN, but it can be used for other cassegrain instruments of the OST.

1796년 9월에 완성된 수원 화성은, 49개 시설물이 5,744m에 걸쳐 조성된 방어시설이다. 일제강점기와 한국전쟁을 거치며 많은 건축물과 성벽이 훼손되었고, 1975년 수원성 복원 정화사업을 통해 현재의 모습으로 복원되었다. 전체 시설물 중 6개 시설물은 도시화에 의해 복원되지 못하였는데, 이 중 은구를 포함한 수(水) 공간의 복원은 관람객들에게 휴식과 조망의 장소로서 활용될 수 있을 것이다. 수원 화성을 방문하는 관광객들은 역사유적지를 탐방하는데에 만족감을 보이고 있으나, 성곽 주변의 자연경관을 즐기는 것에는 부족함을 느끼고 있다. 도시화가 진행된 수원 화성 내에 자연경관을 조성시킬 수 있는 방법으로는 수 공간 조성을 통해 전통정원의 정취를 느끼게 해 주는 방법이 최선의 방법으로 보인다. 따라서 수원 화성의 미복원된 수 공간을 『화성성역의궤』와 『화성전도』 분석을 통해 위치와 형태, 기능 등을 파악하였고, 수 공간의 특성을 분석하여 전통조경 조성방법을 도출하고자 하였다.
