Preservation space is a functionally$\ulcorner$core$\lrcorner$in a museum. Gernerally, it is a common view that collections are exhibited within 5% of total stored collections. So that, part of collections are cycled exhibition space centering around preservation space, and that is a important mechanism of collections circulation in a museum. It is the best way that collections should be $\ulcorner$conserve$\lrcorner$ in a stable condition, but inevitably collections are exposed as stable condition, but inevitably collections are exposed as called $\ulcorner$exhibition$\lrcorner$. For that reason the function of $\ulcorner$exhibition$\lrcorner$. For that reason the function of $\ulcorner$exhibition$\lrcorner$for 'showing' and the function of $\ulcorner$preservation$\lrcorner$for 'conserve'are contrary to each other's concept, so it is principle of scheme that these concepts should be functionally connected with and planned$\ulcorner$match$\lrcorner$. In addition, various studies (for example, comparative analysis of collections, examination of collections for conserved condition or special exhibition, and classification of new item, etc.) are worked in preservation space. Therefore, preservation space should not be considered as a warehouse, should be composed not only$\ulcorner$comfortable place to rest of collections$\lrcorner$but also $\ulcorner$part of study room$\lrcorner$in a museum. So that, environment of museum should be established by plan to preservation and management. The point of plan to museum is that minimize dangerous element for collections, and then develop an essencial element of space for$\ulcorner$conservation$\lrcorner$and$\ulcorner$exhibition$\lrcorner$. The reason why with a few exceptions (buildings which have being exposed or extremely minor part of collections) most of collections have been lasting its life during over hundreds of years with adapting itself to natural features, so scheme of preservation facilities should be made up with understanding and analysis generic character of collections, and then establish proper temperature and humidity environment.

Purpose: Sensitivity analysis offers a good guideline for designing energy conscious buildings, which is fitted to a specific building configuration. Sensitivity analysis is, however, still too expensive to be a part of regular design process. The One-at-a-time (OAT) is the most common and simplest sensitivity analysis method. This study aims to propose a reasonable ground that the OAT can be an alternative method for the variance-based method in some early design scenarios, while the variance-based method is known adequate for dealing with nonlinear response and the effect of interactions between input variables, which are most cases in building energy simulations. Method: A test model representing the early design phase is built in the DOE2 energy simulations. Then sensitivity ranks between the OAT and the Variance-based methods are compared at three U.S. sites. Result: Parameters in the upper rank by the OAT do not much differ from those by the Main effect index. Considering design practices that designers would chose the most energy saving design option first, this rank similarity between two methods seems to be acceptable in the early design phase.

최근, 구조설계 기준 및 평가방법의 전문화로 인하여, 선급 규칙의 통합화가 이뤄졌었다. 그 좋은 일례가 국제공통규칙(CSR, Common Structural Rule)이다. 그러나, 종강도 하중이 크게 작용하는 화물창 구역에만 국한하여 세부규정이 제시되어 있고, 선수와 선미부 구조에는 별다른 평가 지침이 없다. 언급한 구역의 구조설계는 조선사의 설계 경험에 의존하여 진행하고 있으며, 선급에서도 명확한 기준이 없으므로 구조 손상 문제가 발생하더라도 근본적인 원인을 파악하기가 힘들다. 본 연구에서는 선미부에 주로 발생하고 있는 좌굴 손상의 대표적인 사례에 대한 근본적인 원인을 파악하기 위한 엔지니어링 기반의 해법을 제시하였다. 유한요소해석 모델링 기반 구조 강도 검증을 위하여, 하중 조건, 경계조건, 모델링 방법 그리고 평가 기준에 대한 합리적인 해법을 제시하였다. 선미부에 작용하는 휨 모멘트에 의하여 높이 방향으로 압축하중에 의해서 좌굴이 발생할 가능성이 있으며, 좌굴 강성 증가를 위하여 판 두께 증가 혹은 수직 보강재의 추가가 필요하다. 앞으로도 이 결과는 유사 운반선의 선미부 구조 강도 검토 시 도움을 줄 것으로 기대된다.

A barrel cam is used as a very important part of an index drive unit. The index drive unit must have an intermittent-rotational motion. The barrel typed cam and roller gear mechanism has the advantages of high reliability to perform a prescribed motion of a follower. This paper proposes a new method for the shape design of the barrel cam and also a CAD program is developed by using the proposed method. As defined in this paper, the relative velocity method for the shape design calculates the relative velocity of the follower versus cam at a center of roller, and then determines a contact point by using the geometric relationships and the kinematic constraints, where the direction of the relative velocity must be parallel to a common tangential line at the contact point of two independent bodies, i.e. the cam and the follower Then, the shape of the cam is defined by the coordinate transformation of the trace of the contact points. This paper presents two examples for the shape design of the barrel cam in order to prove the accuracy of the proposed methods.

In choreography, the relationship between body and space is fundamental. Not only in the performing arts, it is an essential part in space design as well. In this sense, the comparison study between performing arts and space design will have various helpful aspects from which a creative design can be derived. This thesis aims to study spatial characteristics and expression methods in the choreography of performing arts that is dance in this case. The general background study of the relationship between body movement and space design in the modem art and architecture was explained in advance. And then its application in choreography was studied. Two case choreographers were selected: Merce Cunningham and Frederic Flamand. They have unique ways of designing and choreographing the relationship between body movements and stage spaces. This thesis attempts to find the differences as well as common characteristics between the two choreographers in terms of how they relate bodily movements and emotions into the given space.

This paper endeavors to examine the most suitable formal dress design for mid-aged men who lives in Kwangju, the Republic of Korea. Visual effect in associate design is considered with adjustment, figured and the body type. There are partly similarity differences in associate design visual effect by one's shape and clothes design. Firstly, in thin type, striped figured suit is the most attractive. Single adjustment suit with striped figured tend to be attractive, young and modernistic. Single adjustment without figured is felt the mellowest. Secondly, in standard type, the suit without figured is perceived the most attractive and masculine. The suit with striped figured is looked more young. Single adjustment suit without figured is the most attractive and mellow also single adjustment with figured is felt the youngest. Double adjustment without figured is felt mellow and with striped figured is felt the most modernistic and familiar. Also double adjustment suit with check figured is felt more modernistic. Thirdly, in pyknic type, the solid figured and striped figured of the suits are felt more masculine and single without figured is thought attractive. Single adjustment with check figured is common image. Also, double adjustment with stripe figured is perceived attractive. In conclusion, the adjustment, number of button and figure are very important facts for the clothes for giving whole visual effect of men's suit.

Most manufacturing enterprises create CAD data as a result of the product/part design process; however, the CAD data is being utilized only for production activities. Besides the processes directly related to manufacturing such as design and production, the CAD data is an important resource that can be used in variety of services (e.g., catalog production and production manuals) for manufacturing enterprises. This study proposes a software platform that can support a wide range of services for manufacturing companies in an efficient and productive way. The software platform was designed based on the functions identified by requirement analysis. The platform consists of four layers: data model layer to manage relevant data; library layer and common function layer to configure services; and application layer to install and run the software. Finally, this study evaluates the validity of the proposed platform architecture by applying it to the digital catalog system.

Direct Metal Manufacturing (DMM) is a new additive process that aims to take die making and metalworking in an entirely new direction. It is the blending of five common technologies : lasers, computer-aided design (CAD), computer-aided manufacturing (CAM), sensors and powder metallurgy. The resulting process creates parts by focusing an industrial laser beam onto a tool-steel work piece or platform to create a molten pool of metal. A small stream of powdered tool-steel metal is then injected into the melt pool to increase the size of the molten pool. By moving the laser beam back and forth, under CNC control, and tracing out a pattern determined by a computerized CAD design, the solid metal part is built line-by-line, one layer at a time. DMM produces improved material properties in less time and at a lower cast than is possible with traditional fabrication.

A product consists of some parts. The integrity of a product might not be explained from individual parts. The fishery processed goods can be used as a model. The characteristics which derives from a product as a whole is more important than right or wrong of individual parts. All commodities to appeal for consumers have much in common. I explain the process of producing a new tasteful commodity by observing the fishery processing goods business. This is a part of data acquired from a research at a fishery port in Japan. (1) A project manager should be a person in charge of marketing, which makes success easier. (2) A product and process design should be done concurrently. (3) As for a synthetic architectural commodity, a strong leader is a must. (4) To understand material and sensibility information, we can use the above-mentioned.
