(Background and Purpose) The changed look of architecture that appears in today’s rapidly changing world has a sufficient variety of shapes and spaces to lead the cultural flow of society. In this light, I analyze the interior-exterior relationality and expression characteristics and elements of indoor space, continuing from the interior-exterior boundary defined by the appearance of architecture. I also examine their connection as it is expressed in space. (Research Method) I perform a theoretical examination of interior and exterior spaces by understanding changes in architectural spaces throughout history, grasping the most fundamental concepts and attributes as well as identifying the expression characteristics and elements required for case analyses. The criteria for selecting cases for the study are established by society and culture, which are semantic attributes that form interior and exterior spaces for analyzing earlier studies pertaining to architectural space. The related vocabulary and analytical theories extracted from earlier studies are constructed into a common elemental vocabulary, and the appropriateness of elements selected through the theoretical review is indicated. Accordingly, I distinguish the expression characteristics and elements that belong to the basic principles of composition . The case study is used to identify the types and characteristics of expression elements extracted through a theoretical examination and determination of scope. The case studies show similarities and differences in the use of space (Summary Table 1); characteristics of spaces based on the case studies are identified in Summary Table 2 . (Results) The case study analysis in Summary Table 1 indicates that the relationships between space and areas are closely related to the locations in which the interior and exterior of the architectural spaces are formed; as a result, I have analyzed spatial areas and characteristics in Summary Table 2. Additionally, I could comprehend the connectivity in which the expression elements of space form relationships. (Conclusion) My analysis shows that the expression characteristics of architectural space, which start in the interior-exterior boundary, determine the type and transparency of materials by the degree of their relationships, serving as crucial clues when deciding on the characteristics of the connected indoor space and the arrangement for its various uses. These factors influence the directionality of the expression elements. My analysis shows that they these elements have an impact on the selection of materials and their physical construction. (연구배경 및 목적) 오늘날 급변하고 있는 시대에서 나타나는 건축의 변화된 모습은 사회의 문화적 흐름을 주도할 만큼 그 형태와 공간적 모습이 다양하다. 이에 건축의 외형적 형태에 의한 내·외부 경계로부터 이어져 내부공간에 표현되어 나타나는 모습에서 내·외부 경계의 관계성과 그로인해 나타나는 내부공간의 표현특성과 표현요소를 분석하고 그것들이 어떤 연관성을 가지고 있으면서 공간에 표현되고 있는지 분석하고자 한다. (연구방법) 건축공간의 역사적, 시대적 변화 속에서 건축공간의 이해와 그것의 가장 근원적 개념과 속성을 통해 내·외부공간의 이론적 고찰을 하고 사례분석에 필요한 표현특성과 표현요소를 도출한다. 본 연구의 진행에 있어 사례선정 기준은 내·외부공간을 생성하는 의미론적 속성이라 할 수 있는 사회적, 문화적 측면에서 그 기준을 정하고, 건축 공간 및 내·외부공간과 관련된 선행연구를 분석한다. 선행연구를 통해 추출한 연계어휘와 분석이론은 공통된 하나의 요소적 어휘로 구성하여 앞서 고찰한 이론 고찰을 통해 선정된 요소의 당위성을 명기하고, 이것을 토대로 건축공간의 기본적 구성 원리에 해당하는 표현특성과 내부공간의 표현요소로 구분한다. 그리고, 그것의 이론적 고찰로 추출된 표현요소들의 유형 및 특성들을 도출하고 그 범위를 정하여 사례분석을 진행한다. 사례분석으로 나온 내용은 먼저 용도적 측면에서 나타나는 공통점과 차이점을 종합표-1에서 결과로 도출하고, 종합표-2에서는 그것을 토대로 나타나는 공간의 특성을 영역별 측면에서 결과를 도출한다.

본 논문에서는 경계요소법의 평면 접촉해석에 사용될 수 있는 효율적인 접촉면 검출 알고리즘을 제시하였다. 접촉면 검출 알고리즘을 경계요소법에 적용하기 위하여, 경계요소법이 가지는 자료구조를 분석하였다. 경계요소법의 특징 중 하나인 모퉁이 문제를 고려하여 전역검색, 지역검색, 접촉관계식 설정의 3단계로 접촉면 검출기법을 구현하였다. 전역검색은 접촉 주요소, 부요소 개념을 도입하였으며, 지역검색에 있어서는 공간분할기법인 사지트리를 이용하였다. 접촉관계식의 설정을 위하여 요소수준에서 절점의 접촉여부를 검토하고 최종계의 방정식에 구속조건을 할당하도록 하였다. 제시된 알고리즘을 이용한 프로그램의 정확성과 효율성을 입증하기 위하여 수치해석을 실시하여 결과를 비교하였다. This paper presents an efficient contact detection algorithm for the plane elastostatic contact problem of the boundary element method(BEM). The data structures of the boundary element method are dissected to develop an efficient contact detection algorithm. This algorithm is consists of three parts as global searching, local searching and contact relation setting to reflect the corner node problem. Contact master and slave type elements are used in global searching step and quad-tree is selected as the spatial decomposition method in local searching step. To set up contact relation equations, global contact searching is conducted at node level and local searching is performed at element level. To verify the efficiency of the proposed contact detection algorithm of BEM, numerical example is presented.

This study aims to investigate the physical characteristics and architectural ornaments of the walls (DamJang) and their bordering area that defines the Rear Garden of Changdeok-gung, one of the Royal Palaces in Seoul. This area, centered on Buyong-ji(부용지) and Aeryeon-ji(애련지), features the morphological diversity of buildings, walls, gates and stone bases in the palace. The findings are summarized as follows: First, DamJang, as a basic architectural element for the space organization, takes a set of various forms featuring different construction materials while responding positively to the physiographic nature of the surroundings; Second, DamJang along with their gates, also features different types of ornamental expressions which also suggest the hierarchy of its building and space; Third, typical of the traditional garden design in Korea are a group of DamJang standing as independent structures mostly around Buyong-ji and Aeryeon-ji whose finishing conditions also differ based on the nature of the space; Fourth, among commonly observed examples of DamJang in the Rear Garden and Changdeok-gung palace-wide, is a 'T' shaped wall whose heights and materials function as a design element for the garden.

Bragg reflection of nonlinear waves is simulated by a 2D fully nonlinear numerical wave tank (NWT). The developed MWT was based on the Boundary Element Method (BEM) with potential theory and the mixed Eulerian-Lagrangian (MEL) time marching scheme with Runge-Kutta 4th-order time integration. A spatial variation of wave elevations and their Fourier amplitudes of each component are compared to investigate the effect of sea bottom ripples and their relative heights. The incident waves over an undulated sea bottom are partially reflected and changed to partial standing waves due to Bragg reflection. The present results are verified with linear calculations and experimental data. It is found that the 1st-order wave component is mainly affected by Bragg reflection and its spatial modulation is significant in front of the bottom ripples.

Boundary element solution method is introduced for radiation heat transfer problem with objects inside a 2-D enclosure, where shadow zone exists. Surfaces are assumed as diffuse gray in a transparent medium. Boundary integral and boundary element equations were derived from radiation transfer equation, and their theory is reviewed. Also the process of solution methods to implement the boundary element method is analysed and explained with consideration of shadow effects. BEM solution results are compared with two test problems and are found to be good agreements with the both analytic and ANSYS Fluent numerical solutions. Therefore the current BEM analysis for radiation heat transfer problem can be considered as verified, and their efficacy with engineering applicability is established as a result.
