This study is to plan the interior spaces of cruise ships for domestic services. In order to give directions for planning of interior spaces, a survey was done through questionnaire by Koreans who have experience of travelling on cruise ships. Based on the survey results and other important situations around domestic cruising industry we set up the critical conditions for the interior space design for domestic service cruise ships. And then the data on the cruise ships which have similar conditions with the domestic service cruise ships are analysed. Types and sizes of interior spaces and horizontal and vertical composition of private and public spaces are main concerns in this study.

본 실험은 상업공간 중에서 화장품매장 쇼케이스를 연구대상으로 하여 바람직한 쇼케이스 조명환경을 제시하고자 실험을 실시하였다. 쇼케이스 조명의 실험 결과, "명시성" 과 "차별성" 을 얻기 위해서는 내부 조도를 높게 하고 균등하게 밝히며, "정서성" 을 얻기 위해서는 적당한 조도로 수평 뒷면 조명과 수직 앞부분 조명을 하여 음영의 효과를 얻는 것이 좋은 것으로 나타났다.

We present a new method of measuring the volume and cross-sectional area of the vocal tract from magnetic resonance images. The vocal tract was divided by the 2 constriction points on the horizontal and vertical planes. The ratios of the volumes of the segment vocal tracts to that of the entire vocal tract play a crucial role in discriminating Korean monophthongs in that vowels were successfully discriminated by the ratios. The discriminant analysis also demonstrated that the acoustic parameters F1 and F2, in addition to the segment volumes, serve as significant parameters in discriminating Korean monophthongs.

본 연구에서는 터널의 주요 설계정수인 탄성계수와 측압계수를 산정 할 수 있는 역 해석 알고리즘을 개발하였다. 해석 알고리즘은 범용 유한차분해석 프로그램인 FLAC의 해석과정 내에 직접탐색법 알고리즘을 이용한 FISH 문을 삽입함으로써 구성하였다. 기존 연구에서 사용한 탄성모델에 대하여 본 연구에서 개발한 역 해석 알고리즘의 적합성을 검토하였다. 본 연구에서 개발된 역 해석 알고리즘은 기존 역 해석 기법에 비해 더 적은 반복연산에 더 정확한 결과를 얻을 수 있음을 확인하였다.

This study is searching the characteristics of transferred element in composition of architectural spaces ; it is ultimate goal that frame of reference is arranged system about path of horizontal direction is two-dimension and stairs of vertical in three-dimension as transferred element in Architectural plan. With the exception of stylized discussion or rhetorical analysis about these, it is analysed as element in physical order of a whole architecture in relation to another elements in composition of architecture spaces. And one who is perceptible and cognitive through spaces is the subject. Consequently , these elements are classified concept of location and circulation. And it can't think that the formal is divided the latter for accept behavior of pedestrican and thinking system to consider verticality and time property is absolutely conceptual elements in space of architectural plan.

침식에 따른 횡방성 암반의 초기응력비 변화를 수치해석적으로 구하여 등방성의 경우 및 이론해와 비교한 결과 횡등방성의 영향은 크지 않아 초기지응력비가 작고 침식심도가 깊을 때만 고려하는 것이 좋을 것으로 판단되었다. 수치해석에 의한 응력과 이론적인 값의 차이는 초기 지응력비가 클수록 또 침식되는 깊이가 증가할수록 증가하였다. 또 침식 후의 초기응력비는 심도가 깊어짐에 따라 초기 응력비로부터 발산하였다. 이를 감안하여 침식에 따른 초기응력비 산정식을 제안하였다.

The purpose of this study is to develop precast concrete modules that can be used as a booth and a single-story building with a large space. This precast concrete module is originally designed to have a hexagonal facade when the upper and lower parts, which are symmetrical about horizontal connection line, are combined. A structural design was conducted to ensure structural safety of these precast concrete modules and to extend the slope of the inclined members as far as possible. Then the finite element analysis was performed to estimate the lateral and vertical deflection of complete precast concrete modular structures. And to verify the structural safety of these precast concrete modules, weight loading tests were conducted on the upper and lower modules respectively.

Along with the development of creative design ideas, how to effectively present design concepts is also an important consideration on housing plan process. This could consequently make it possible to automate presentations. In spite of such needs of presentations any significant efforts for the systematic design presentation have not been made yet. The research goals established in order to solve these problems are to develop structures of presentation and analyze the cases of it. This paper explains structures of housing plan presentations in two ways: the compositional elements of panel presentations and the relationships among the elements. The elements include a project title, a synopsis, design concepts, building layouts, floor plan1 and 2, longitudinal and latitudinal elevations, sections, projection and perspective views, and model photographs. Among various relationships among panel compositional elements this study uses relationships based on the Gestalt theory, the balance theory by Rudolf Arnheim and the optical array theory by Gibson. The relationships investigated on the basis of the visual perception theories include the relationships between compositional elements and background space, visual weight balance, horizontal and vertical balances, grouping, and visual layout patterns.

For underwater milling of parts of nuclear reactor, a waterproof main spindle system was developed. which used a servo meter. Particularly, a waterproof system is available to cope with emergencies such as an electricity failure so that it prevents hazards from cutting radioactive materials. A developed spindle was designed to be capable of horizontal and vertical cutting and structural analysis was conducted with a FEM tool(Design Space) when the forces were loaded in each axis-direction.

Recently, mega-float offshore structure is studied as one of the effective utilization of the ocean space. And mega-float structure are now being considered for various applications such as floating airports, offshore cities and so on. This mega-float structure is relatively flexible compared with real floating structures like large ships. when we estimate dynamic responses of these structures in waves, the elastic deformation is important, because vertical dimension is small compared with horizontal. The analysis of the dynamic response as it receives regular wave is studied. The finite element method is used in the analysis of structural section of this model. And the analysis is carried out using the boundary element method in the fluid division. In order to know the characteristics of the dynamic response of the mega-float structures, effects of wavelength, water depth, and wave direction on dynamic response of the floating structure are studied by use of numerical calculation.
