The purpose of this study is to empirically analyze the effect of cultural distance between partner firms on international joint venture performance, focusing on the moderating effects of the conflict resolution techniques and the competitive relationship between partner firms. We tested hypotheses based on joint venture firms that were surveyed which formed by equity investment between Korean and foreign firms in the manufacturing industry. The empirical analysis results of this study are as follows. First, in international joint ventures, the cultural distance between partner firms was found to have a negative effect on the international joint venture performance, and the higher the cultural distance, the lower the joint venture performance. Second, it was found that constructive conflict resolution techniques weaken the negative impact of the cultural distance between partner firms in international joint ventures on the performance of international joint ventures. Third, competitive relationship between international joint venture partners showed no moderating effect on the relationship between cultural distance and international joint venture performance.

The purpose of this study was to identify the constructive principle and techniques of Vionnet's works. According to analysis of Vionnets works, it was found that Vionnet conceived of the human body as a continuous shaping of a cylinder. Vionnet's drapery denied the planner presumption of woman and gave real three-dimension to form and to fashion. The techniques of Vionnet's works were as fallow : (1) She introduced the diogonal "bias cut" and changed dress design by her sensuous use of fabrics. (2) She eliminated interfacing to keep the silhouette and the fabric soft. (3) She manipulated the fabric to remove the excess for fit and decoration at the same time. (4) She treated the fabric with a synthesis of geometry and grace. (5) The sale luxury allowed was to note the choice of seams, facings, hems, and stitches. (6) Vionnet's dresses were not lined.

3차원 물체를 표현하는 솔리드 모델링 기법으로 Constructive Solid Geometry(CSG)와 경계표현 (Boundary Representation: BRep)이 널리 쓰이고 있다. 현대의 솔리드 모델링 시스템들은 대개 이 두 기법을 모두 지원하고 있으며, CSG와 BRep간 상호 변환은 매우 중요한 문제이다. 하지만, BRep에서 CSG로의 변환은 아직 완전히 해결되지 않은 과제이다. 이 논문은 BRep을 CSG의 특수한 형태인 Destructive Solid Geometry(DSG)로 변환하는 3차원 기하 추론 알고리즘을 소개한다. BRep에서 DSG를 만들어내는 알고리즘은 CAD와 CAM을 통합시키는 특정 형상 인식 분야에 직접 응용될 수 있다.

This paper describes a C++ class hierarchy of implicit objects for geometry modeling and processing. This class structure provides a software kernel for integrating many various models and methods found in current implicit modeling areas. The software kernel includes primitive objects playing a role of unit element in creating a complex shape, and operator objects used to construct more complex shape of implicit object formed with the primitive objects and other operators. In this paper, class descriptions of these objects are provided to better understand the details of the algorithm or implementation, and its instance examples to show the capabilities of the object classes for constructive shape geometry. In addition, solid modeling system shown as an application example demonstrates that the proposed implicit object classes allow us to carry out modern solid modeling techniques, which means they have the capabilities to extend to various applications.

This research was focused on the changes of layered techniques in Hussein Chalayan's collections. For this purpose, the layered techniques in 134 works from Chalayan's collections, 97S/S to 06S/S, which were obtained from fashion magazines and fashion internet site, were analyzed and classified into 15 groups. Layered techniques in his works apparently expressed his philosophy about deconstruction. Multilayered feeling was given through using various techniques such as one layer clothing which was showed like multi-layered clothing. Others were multi-layer clothing which felt like one layer, breaking the stereotyped line of clothing into atypical construction and using various materials or constructive lines which made the optical feeling like one layer or multi-layer clothing, and so on. These layered techniques in Chalayan's collections were differentiated into several categories, such as techniques which were revealed in every collections, techniques which were differentiated from one another collections, techniques which were continuously showed through three collections for connection with each collection, techniques which were used only for Spring/Summer season, and techniques which were uniquely showed in early collection or recent collections.

The purpose of this study was to develop questions for fashion design development, by applying 7 elements of the scamper to the fashion design elements, and to present a scamper checklist of fashion design elements, and item structures. In this study, the scope of research was limited to clothing design among various fashion products, and among various design development stages. Fashion design development focusing on design sketching, was limited to the research scope. The research method was based on an empirical study that derived scamper questions through FGI (Focus Group Interview), consisting of 5 fashion experts. Fashion design elements applied to development of scamper questions consisted of silhouettes, constructive lines, structural details, decorative details, patterns and textures of fabrics, and item structures, derived by applying these elements to the individual 7 elements of the scamper: substitute, combine, adjust, modify, put to other uses, eliminate, and reverse. Results of the study included 7 questions for substituting, 8 questions for combining, 6 questions for applying, 15 questions for modifying, 4 questions for putting to other uses, 4 questions for eliminating, and 7 questions for reversal. The scamper checklist for fashion design elements and item structures drew to 5 lists of silhouette variations, 7 lists of constructive line variations, 11 lists of structural detail variations, 10 lists of decorative detail variations, 11 lists of fabric variations, and 9 lists of structural modifications of items.

서양철학의 근간을 이루는 데카르트의 이성주의적 인간이해의 반성으로부터 등장한 구성주의는 지능을 포함한 인간이해의 새로운 대안이 될 수 있을 것으로 생각한다. 구성주의는 진화생물학, 진화심리학, 뇌과학, 시스템이론, 복잡계 이론의 성과뿐만 아니라 나아가 인문사회학의 경향과도 설명을 공유할 수 있는 많은 부분이 있다. 또한 인공지능 분야에서도 구성주의적 방법이라고 할 수 있는 연구가 진행되고 있다. 이 글에서는 구성주의적 관점에서 인공지능에서 다루는 지능에 대한 이해의 지평을 넓히고 이를 기반으로 한 방법론에 대한 검토와 그러한 경향에 있는 일부 인공지능 기술을 살펴보고자 한다. 이러한 논의를 통하여 여러 가지 관점의 마음에 대한 이론과 기술을 상호보완적으로 이해하고 다소 등한히 되고 있는 인공지능의 보편지능(general intelligence)의 토대로 삼고자 한다.

본 연구는 울산지역 누정(樓亭)의 특성을 현장 문헌조사 통해 고찰하였으며, 목적은 울산지역 누정의 규모 형태 입면 구조 등을 분석하여 형태특성을 규명하여 누정의 콘텐츠화에 기초자료를 마련하는데 있다. 울산은 1960년대 이후 공업화의 일변도를 걷다가 최근 생태와 문화에 관련하여 관심이 고조되고, 특히 영남의 3대루 중의 하나였던 태화루와 사적으로 지정되어 있는 언양읍성의 영화루 복원 등 누정에 대한 콘텐츠 개발에 적극성을 보이고 있다. 하지만 울산의 누정에 대한 조사가 미흡하여, 기초자료 확보 및 울산 누정의 특성을 파악하지 못하였다. 이에 이번의 연구가 있었고, 그 조사결과 울산의 누정은 경주지역의 정면3칸 후면부진입형 강변입지형 누정과 유사함을 찾아내었다. 이는 울산이 고대로부터 경주문화권에 속해있었기 때문으로 사료되며, 누정이 인접지역간 콘텐츠 융합의 좋은 대상이라는 점을 찾아낸 것에 서 연구의 의의를 찾을 수 있다.

One of the important open problems in modeling plants is the extension of subdivision algorithms to branching structures. Most of the applications use the concept of L-system to produce branching structures as a sequence of lines and apply the subdivision scheme to appear as curves. In this paper, we explain how L-systems can be modified to produce branching structures. This is also very useful for generating the geometry of various shapes. The proposed technique, called an adaptive L-System, describes branching forms and leaves by making local curve without applying the subdivision steps. Advantages of the suggested algorithm over previous techniques are given. Validation of the algorithm are discussed, analyzed and illustrated by some experimental results.

The cooperative communication systems using MIMO(multiple input multiple-output) relay are known as one of the most promising techniques to improve the performance and coverage of wireless communication systems. In this paper, we propose the cooperative communication systems using the relay with multi-antennas and DSTC(distributed space time coding) for decode-and-forward protocol. As using DSTC for DF(decode-and-forward), we can minimize the risk of error propagation at the wireless system using relay system. Also, the MIMO channel cab be formed by multi-antenna and DSTC at the MS(mobile station)-RS(relay station) and at the RS-BS(base station).Therefore, obtaining truly constructive the MIMO diversity and cooperative diversity gain from the proposed approach, the performance of system can be more improved than one of conventional system (relay with single antenna, no relay). The improvement in bit error rate is investigated through numerical analysis of the cooperative communication system with the proposed approach.
