Although many stadiums around the world have incorporated various profitable facilities, many are making conventional and cursory decisions without deep consideration of the interrelationships of different programs. This paper investigates cases in which new programs such as a hotel, a youth hostel, and a dormitory have been introduced into stadiums, showing different results. In the first part of this paper, the theoretical precedents of program combination are studied. Although Bernard Tschumi's notion of the combination of different programs presented its prophetic probability, this paper discern different approaches addressing program mixture, engendering eventually a productive modification of his notion based on the empirical observation of the cases. This paper classifies the manner of programmatic combination into complexity and hybridity, arguing that the latter transforms the spaces and gives rise to unexpected synergy, while the former merely assembles different programs. The second part compares the spaces of complexity and hybridity in stadiums. Through the plan and the section analysis of the spatial structure and the interrelationship of programs, this section reveals how the two different ways of the program combinations have had different results. In hybrid stadiums, programs are not simply gathered, but directly connected and intertwined. In the third part, the nature of the spatial transformation in the hybrid space is researched in detail. In the hybrid stadiums, the collision of the different programs changes the conception of the programs themselves and their related spaces. Hotels and stadiums are not what they once were, provoking unanticipated situations. These transformed spaces not only suggest a method of reutilizing of disused urban spaces, but also of meaningful and communicative program mixture, diversifying and vitalizing a city, not isolated islands of discrepancy. The ultimate purpose of this paper is clarifying the programmatic hybrid paradigm, surpassing complexity through the analysis of the stadium cases and illuminating the manner by which the hybridity breaks the typical tie between the program and space, to cause transformed situations.

This research identifies the elements of the methodologies of Newton's discovery of his dynamics. These methodologies involve the transformation of preceding theoretical concepts and the discovery of common cause. This essay consists of two parts within historical case studies of Newton's works. The elements of the method of discovery consists of the transformation of preceding concepts and the identification of common cause in the formation of the research program's hard cores and protective belts. Newton transformed their predecessors' concepts to find out appropriate common causes in his dynamical theory. The transformed theoretical concepts are synthesized to be constructed as the elements of common cause which provide the foundations of Newtonian research programs.

공간정보 시스템의 구축과 운영에서 메타데이터는 핵심 요소 중의 하나이다. 따라서 국내외 표준화 기구나 단체에서 현실적인 수요를 반영한 다양한 메타데이터를 개발 공표하고 있다. 그리나 국제 표준이나 국가 표준 등이 많은 항목으로 구성되어 있고 메타데이터 서버를 구축하는 경우에는 XML 형식으로 저장, 관리할 필요가 있기 때문에 실무 응용 시스템에서는 표준 형식을 따르기 보다는 운영 기관별로 별도의 메타데이터 사양을 설정하여 사용하는 경우가 많다. 따라서 본 연구에서는 국제 표준인 ISO/TC 19115와 TIAS.KO-10.0139와 TTAS.IS-19115와 같은 단체 메타데이터 표준으로 손쉽게 입력할 수 있도록 직접 공간자료 포맷으로부터 메타데이터 항목과 요소를 추출하여 직접 XML로 저장할 수 있는 프로그램을 개발하였다. 본 프로그램에서 공간영상정보에 대한 자료 포맷의 경우에는 ISO/TC 19115-2 메타데이터 표준 사양으로 추출, 저장할 수 있도록 하였다. 한편 메타데이터 표준간의 항목이나 요소들이 일부 상이하기 때문에 메타데이터 추출 가능과 함께 메타데이터 간의 변환 기능을 개발하여 메타데이터의 상호 운영이 가능하도록 하였다. 본 연구에서는 활용도가 높은 자료 포맷을 대상으로 하였으나 기타 자료 포맷이나 기관별 메타데이터 사양을 처리할 수 있는 확장 기능 구현을 통하여 메타데이터 표준의 활용도를 증가시킬 수 있을 것으로 기대한다.

A pre-processing program based on the OOP(object-oriented programming) concept has been developed. The program consists of the input of a 2D or 3D flow problem to a CFD program by means of an user-friendly interface and the subsequent transformation of this input into a form suitable for the solver(PowerCFD) using unstructured cell-centered method. User-friendly GUI(graphic user interface) has been built on the base of MFC(Microsoft Foundation Class). The program is organized as modules by classes based on VTK(Visualization ToolKit)-library, and these classes are made to function through inheritance and cooperation which is an important and valuable concept of object-oriented programming. The major functions of this program are introduced and demonstrated, which include mesh generation, boundary settings, solver settings, generation of grid connectivity and geometric data etc.

When the contribution of lightweight components to the total energy of a system is small, tole inertia effects are sometimes ignored by replacing them to massless links. For example, a revolute-spherical massless link generates two kinematic constraint equations between adjacent bodies and allows four relative degrees of freedom. In this paper, to implement a massless link systematically in a computer program using the velocity transformation technique, the velocity transformation matrix of massless links is derived and numerically implemented. The velocity transformation matrix for a revolute-spherical massless link and a revolute-universal massless link are appeared as a 6$\times$4 matrix and a 6$\times$3 matrix, respectively. A massless link model in a suspension composite joint transmitting external forces is also developed and the numerical efficiency of the proposed model is compared to a conventional multibody model. For a massless link transmitting external forces, forces acting on links are resolved and transmitted to the attached points with a quasi-static assumption. Numerical examples are presented to verify the formulation.

Reproducibility of injection molding machines are studied at the study of this time. We applied computer aided engineering program so it could generate clamping force, about 1,500 kN, to the nozzle center part of flex link in tie-bar and at this time, we made sure condition of stress distribution and transformation quantity in flex link. The result of computer aided engineering transformation quantity was confirmed that transformation of top area was 247~257 kN and bottom areas was 273~279 kN and also was confirmed that the stresses are distributed in a range of 57~750 $N/mm^2$ from top to the bottom of the surface. This time we could confirm the condition of transformation quantity and stress distribution by enforcing the previously used structure analysis of flex link. And we utilized the reference data to establish important point of section for non destructive test overhaul.

The study aims to investigate new theoretical approaches in an effort to resolve conceptual contradictions regarding the impact of organizational culture on developing culture for change, first by providing socio-structural frameworks supporting intrapreneurship, and second through encouraging professional culture behavior with management practices or organizational members acting as agents of change forming a deeper culture of values and behavior. The design of this research is quantitative. This study employs survey data of managers and section heads, which met the sampling requirements. Data analysis in this research used structural equation modeling (SEM) with the help of the AMOS program. The results show that all hypotheses are supported. The findings of this study suggest that the organizational culture transformation and dyadic social intrapreneurship based on professional culture (DSIBPC) have significant positive influence as antecedents of competitive advantage. This research also shows that DSIBPC is able to act as an important mediator that fills a gap in the relationship between organizational culture transformation toward competitive advantage, as well as being an alternative strategy for organizations in an effort to increase their competitive advantage. Referring to the results of this research, organizations need to focus and pay attention to the DSIBPC.
