This research is aimed to discuss for Korean cultural contents; symbol structure of Minwha painting which not only expresses openness, flexible expression and methods of communication of our ancestors but also possibly passes down as precious cultural heritage to modern society with new developed mediums. From this perspectives, as a method of research, modern jewelry design is created through digital process with linguistics analysis of its symbol structure that contains universal wishes of people. As a result, this research showed jewelry design and design process, titled "Blossom" and "Big Smile" grafting modern technology of 3D digital tool onto universal meaning symbolized by Peony flower, wealth and honor, and also grafted modern manufacturing methods of 3D printing and laser cut onto openness and flexible thinking in symbol structure in Minwha.

Since the movements of a machine are driven by a certain principle, there is a fundamental principle that governs the movement of the machine, no matter how complex and diverse it may be. Autonomous movements are a way to avoid repetition, to approach more humane and more natural factors. That's all the more so when it comes to original movements, not cloning. So now, the dynamics of the machine are more multi-sensory by human participation. It is challenging the potential to be expressed and is gradually expanding its sphere of expression in the boundaries of fact and cloning. Theo Jansen's works have changed from period to period to adapt to different circumstances, indicating that his decades-long work has continued to evolve from early to present. The evolution's focus, among other things, can be seen as having the same source of circular motion and horizontal reciprocating motion, which are repeated from the principle of organic coupling between the parts that make up the object.

This paper attempted to explore the plausible reasons why change activities to build up organizational trust might be often short-lived, even though it can become the most valuable social capital for an organization. Based upon a reference data collected from a large company in various methods, retrospective rationalization, difficulties embedded in the processes of realizing the five bases of organizational trust (such as openness, consistence, fairness, consideration, and pride), and top management's negative conviction were identified and discussed as fundamental reasons for the distrust in the usefulness of organizational trust. In addition, middle managers' overcautiousness about their superiors' feeling and organizational cynicism as contributing factors for the distrust in the form of vicious circle were discussed.

In this paper, we provide a summary on the core essence of INR (Image Navigation and Registration) System technology which is an essential function of geostationary remote sensing satellites. Its origin and evolution history is reviewed, its core elements and governing concept for each element are described, and a generic INR architecture is suggested which can cover all seemingly conceivable INR systems of the past, the current and the future. By this, we intend to identify and illuminate the core technical contents and the key aspects in the foreseen prospect of the up-coming INR systems and the related technologies.

대부분의 건축가들에게는 규제 및 통제는 난센스라 생각되는 수가 있는데 이는 훌륭하게 설계된 건물이라 할지라도 그 건물을 법적으로 금지할 때가 종종 있기 때문이다. 건축분야에서 가장 진보된 규제 및 통제 방법은 건축기준과 지역ㆍ지구에 관한 규제(Restrictive Building Code & Zoning Ordinances)이다. 이 이외에 상식적으로 생각하더라도 여러 가지 제한을 들 수 있는데, 의뢰자의 취미, 융자조건, 여산, 재산세, 기후 및 대지조건과 기계설비의 제한요소가 있겠다. 우리는 건축 및 도시의 복잡한 미로에서, 우리의 주위 환경 속에서 인간의 목적과 희망을 달성하기 위한 규제들 중 어느 것이 최우선이어야만 되는가에 대한 통찰력을 잃어버렸다. 이런 문제들은 건축가에만 국한되지 않는다. 진정 여기에서 우리는 이 시대의 중요한 사회적, 정치적 문제점-공공권리와 개인권리의 공공책임과 개인책임의, 그리고 개인주도력과 공공주도력과의 한계에 직면하게 된다. 더구나, 이런 분야의 한계는 불명확해지며 더욱더 복잡화되며 다루기 어려워져 가고 있다. 본 장에서는 건축을 규제하는 요소들을 조사하겠다. 그리고 현 통제체제의 정신, 그 근원, 문제점, 단점, 타당성, 그리고 적용에 관하여 논해보기로 한다.

It is the aim of this paper to find the requisites for the target problem solving process in reference to the base problem and to search the roles of those. Focusing on the structural similarity, analytic activity and comparative activity in stage of similar mathematical problem solving process, we tried to find the roles of them. We observed closely how four students solve the target problem in reference to the base problem. And so we got the following conclusions. The insight of structural similarity prepare the ground appling the solving method of base problem in the process solving the target problem. And we knew that the analytic activity can become the instrument which find out the truth about the guess. Finally the comparative activity can set up the direction of solution of the target problem. Thus we knew that the insight of structural similarity, the analytic activity and the comparative activity are necessary for similar mathematical problem to solve. We think that it requires the efforts to develop the various programs about teaching-learning method focusing on the structural similarity, analytic activity and comparative activity in stage of similar mathematical problem solving process. And we also think that it needs the study to research the roles of other elements for similar mathematical problem solving but to find the roles of the structural similarity, analytic activity and comparative activity.

본 연구의 목적은 유비쿼터스 환경에서 디지털 미디어와 도시경관과 결합한 형태로 나타난 제3의 공간인 도시 경관 미디어의 디자인 방향성 제시와 분석틀을 제안하는데 있다. 디지털 미디어 기술의 다양성과 독창성은 도시 환경을 미학적으로 향상시킴과 동시에 문화컨텐츠의 중요성을 부각시킴으로써 도시의 정체성을 높이는 원동력이 될 것이다. 도시 경관은 도시 활동의 근원으로써 정보의 공급 역할, 공공의 장으로서 휴식과 나눔의 기능, 담론의 장으로서 커뮤니케이션 공간 기능을 담당해야 한다. 이를 위해 도시 경관 미디어 시설물 평가요소 도출과 디자인의 방향성을 제안하고자 한다.

Digital library technology is facing issues such as interoperability, content extension, and the need for a more efficient management environment. A system that is based on standardization and interoperability is required to resolve these issues. Open Digital Library is the system for the next generation that resolves the above problems. We have conducted some research on issues such as OAI and OAI-PMH, which are the basic knowledge behind the Open Digital Library technology and also investigated the Open Digital Library framework, cases of study and implementation of this technology. Finally, we have made some suggestions on the extendability of Open Digital Library technology using the standardized technologies.

Purpose: The construction industry is a complex mechanism in which multiple processes are carried out at the same time, and the frequency and severity of accidents account for a higher proportion than other industries, and the accident fatality rate also accounts for more than 50% of all industries. In order to reduce such accidents, the government's disaster investigation method analyzes the limitations from the system safety point of view and proposes improvement plans. Method: The main contents of the government's serious accident investigation were identified, and the effectiveness/adequacy was analyzed from the system safety point of view. Result: Disaster investigation and analysis techniques tailored to violations and compliance were limited in providing fundamental solutions, and alternatives for accident prevention were possible for each component of the system when safety constraints, controls, and hierarchical interactions were combined. Conclusion: When combining the disaster investigation and analysis method from the current accident analysis method from the perspective of system safety, it is possible to identify the problems of interaction by class and communication process, so it is possible to suggest alternatives to prevent accidents from an integrated perspective.

The fiber-reinforced composite materials have been advanced for various applications because of their excellent mechanical and electromagnetic properties. On their manufacturing processes, however, thermo-curing inherently produces the undesired thermal deformation mainly from temperature drop from the process temperature to the room temperature, so called spring-back. The spring-back must be understood especially in the hybrid composites in order to design and fabricate desired shape. In this research, (glass fiber / epoxy) + (carbon fiber / epoxy) unsymmetric hybrid composites were fabricated under various conditions such as cure cycle, laminate thickness, stacking sequence and curing sequence. Coupons were made and spring-back were measured using coordinate measuring machine (CMM). Using the Classical Lamination Theory (CLT) and finite element analysis (ANSYS), the behavior of spring-back were predicted and compared with the experimental data. The results from CLT and FEA agreed well with the experimental data. Although, the spring-back could be reduced by lowering curing temperature, at any case, the spring-back could not be removed completely.
