Sandwich sheet with inner structure is expected to find many applications because of high stiffness to mass ratio. In order to simulate forming of sandwich sheet with pyramid core, an effective simulation method is required. Compared to the expensive model using solid elements, cost effective model using simplified elements such as shells and beams is developed. By comparing two models in terms of the cost and accuracy for unit cell deformation, a developed model shows some advantages over the model using solid elements. Evolution of two kind of forming limits, face buckling and core buckling are successfully expressed by developed model. Developed model is also applied in the simulation of square cup drawing and L-type bending. The corresponding experiments are carried out. Deformation shape and wrinkling behavior are compared and discussed. It is found that simulation results using a developed model are in good agreement with experiments.

Contemporary objectives for steel rod rolling processing are increasingly complex and often contrasting i.e. obtaining a desired product with optimum combination of properties such as strength, toughness and formability at lower cost. Low-alloy steel rods have been produced with several heat treatments for drawing and forging processes at room temperature. In order to reduce these heat treatments much of the researches concerning of high temperature mechanical behavior of steel rods have been conducted at wire rod mill of POSCO. In this present work, optimizations of rolling temperature and cooling rate for JS-SCM435 are performed to eliminate softening heat treatment(Low Temperature Annealing) for drawing process. The results from the optimization changed the microstructure of rods after rod rolling from Bainite with high tensile strength of 1000Mpa to Pearlite and Ferrite with appropriate strength of 750Mpa that is equivalent tensile strength after softening heat treatment.

본 논문은 비싼 신호보내기 이론과 자기향상동기를 중심으로 주도적 성격과 지식 공유 행위 간 관계, 그리고 더 나아가 조직의 인정 간 관계를 검증하였다. 개인의 성격적 특질에 더하여, 상황적 요인으로 직무 특성을 고려하였는데, 본 논문에서는 직무 복잡성과 다양성이 주도적 성격과 지식 공유 행위, 조직 인정 간 정(+)의 관계를 조절할 것이라는 조절된 매개모형을 제안하였다. 한국 기업들을 대상으로 상사-부하 쌍(dyad) 설문을 실시하여 총 166쌍의 응답을 실증 분석한 결과, 예측한대로 주도적 성격을 가진 구성원일수록 지식 공유 행위를 보다 많이 보이는 것으로 나타났으며, 이러한 지식 공유 행위는 조직 내 상사가 평가한 조직 인정을 궁극적으로 높이는 것으로 나타났다. 뿐만 아니라, 직무 복잡성과 다양성이 높을 때가 낮을 때보다 지식 공유 행위에 의해 매개된 주도적 성격과 조직 인정 간 정(+)의 관계를 보다 강화하는 것으로 나타나 예측한대로 조절변수 관련 가설들도 지지되었다. 이러한 결과들은 조직 공유의 동기가 무엇이고, 이를 활성화시키는 경계조건들이 무엇인지를 밝힘으로써 지식경영 분야에 이론적 실무적 함의를 제공한다고 할 수 있다.

This research work was aimed at assisting isolated children to adapt their school life having examined the process of their changes by reducing isolation level and isolative behavior through means of implementing group art therapy program. To accomplish this purpose of research, 36 participants were selected from children attending Class 6, 4th Grade of D Elementary School located in Dajeon Metropolitan City, to which researcher was served as homeroom teacher. And the participants were asked to complete a survey that included social and emotional isolation scale test which was designed by Heh Sung-hee(1993) and 4 children marked more than 96 points were designated as isolated children. The group art therapy program exercised in this research was the one that reorganized by research to suit the research purpose based on the precedent works, and survey was conducted total 12 times, two time a week, within 60 minutes per time, between 6 September and 24 October 2006, and researcher conducted group art therapy program directly at Class 6, 4th Grade of D Elementary School using extra hours after school. And following analyses were performed in relation to results therefrom: First, to analyze changes of isolation level of isolated children Quantitatively, the results from pre and post test concerning social and emotional isolation scale were comparatively analyzed. Second, to analyze changes of psychological state of isolated children, projective drawing tests were performed using Kinetic House-Tree-Person(K-HTP) Drawing and Kinetic School Drawing(KSD) and results therefrom were comparatively analyzed. Third, to analyze Quantitatively what changes have been occurred in the isolated children during the course of forming interrelationships with group members while participating in group art therapy, proceedings were summarized per each stage of the program and analyzed accordingly. Fourth, results from researcher's observation of what changes have been occurred in the isolative behavior of isolated children before and after implementation of group art therapy were compared accordingly. Followings are resulting conclusions. First, group art therapy program reduced isolation level of isolated children. Second, group art therapy program changed the isolated children's psychological state into a stable and positive fashion. Third, isolated children became able to experience positive interrelations as well as establishment of new human relationships with group members during the course of participating in the group art therapy program. Fourth, group art therapy program reduced isolative behaviors of the isolated children. Therefore, conclusions could have been reached that the group art therapy program implemented in this research reduced isolative behaviors of the isolated children, and changed their anxious and depressed mental state into stable and positive ones, also established positive interrelationships as well as new human relationships. And, it will be able to expect a greater effect if a program which has been associated with their family could be proceeded along with continuous guidance and teaching having developed objective test tools that will discern isolated children.

본 논문은 조직 내 지식 공유에 있어 동료 효과와 성별 효과를 검증하는 것을 목적으로 한다. 즉, 본 논문은 동료의 사회적 태만과 지식 공유 간 어떠한 관계가 있는지, 그리고 동료의 사회적 태만과 지식 공유 간 관계에 있어 성별 차이가 어떠한 상이한 영향을 미치는지를 살펴본다. 이를 위해 본 연구에서는 경제적 사회적 교환관계이론에 근거하여 동료의 사회적 태만에 대해 강하게 인지할수록 개인의 지식 공유 정도는 감소할 것이라고 예측하였다. 이에 더하여, 이러한 지식 공유 감소 효과는 여성에 비해 남성의 경우 보다 크게 작용할 것이라고 가설화하였다. 이러한 가설 검증을 위하여 상사-부하 설문(170부)을 바탕으로 위계적 회귀분석을 실시한 결과, 이론 부분에서 예측한 바와 같이 동료의 사회적 태만은 개인의 지식공유 행동을 저하시키는 것으로 나타났다. 뿐만 아니라, 이러한 지식 공유 저하 효과는 여성에 비해 남성의 경우 감소 폭이 보다 큰 것으로 나타났다. 이러한 이론적 논의와 실증 결과를 바탕으로 본 연구가 가진 함의와 한계를 결론에 제시한다.

The purpose of this study was to investigate the relationships between demographic variables and seven aspects of clothing behavior of adult males, and to attempt to develop the measurement of men's clothing behavior. Age was ranked by five gradation (20∼60 ages) and socio-economic status was divided into three categories (high, middle, low) based on the subjects' education, occupation and economic status. Six aspects of clothing comfort, satisfaction, status symbol, conformity, fashion interest and clothing acceptance I were assessed with Koh's, Chung's and Lee's questionnaires. Clothing acceptance by line-drawing of clothing syles representing different levels of formality for occasions designed to measure the awareness of appropriate clothing category of business suits. The questionnaires in this study were administered to a sample of men living in Seoul. The sample was drawn by the random-cluster sampling method. The data from 362 respondants were analysed. To determine the internal validity of clothing behavior mesurement, factor analysis was computed, whereas to determine the reliability, Cronbach's alpha was calculated. The statistical methods adopted were correlation, one-way ANOVA, and multiple regression. The results obtained in this study were as follows: 1) As for clothing behavior instruments, items dealing with status symbol and fashion nterest were proved to be satisfactory as a measurement of adult males. Eight factors emerged on clothing acceptance Ⅱ, most of which were representing unappropriate clothing choice for occasion. 2) Demographic variables were significantly related to the adult males' clothing behavior. (1) Age was positively related to clothing conformity but negatively to fashion interest. (2) Socio-economic status was positively related to clothing satisfaction, status symbol, and fashion interest but negatively to clothing confort. (3) When age was controlled, socio-economic status was negatively related to comfort in 40∼50s age group only, and negatively related to clothing conformity in 20∼30s age group only. (4) Four subscales of clothing acceptance Ⅱ representing unappro-priate clothing practice for selected occasions were negatively related to age and/or socio-economic status.

상업용 소프트웨어에 견줄만한 수준의 오픈소스 소프트웨어들이 등장함으로 인하여, 오픈소스 (정보시스템 개발) 프로젝트에 대한 학계의 관심이 고조되고 있는 가운데, 오픈소스 프로젝트의 관리경영측면에 관한 연구들은 막상 찾아보기 쉽지 않은 상황이다. 이러한 현실에서 본 논문은 기존의 전통적인 정보시스템 개발관리에 적용되는 경영관리 이론들이 오픈소스 프로젝트에도 그대로 적용될 수 있는 지를 살펴보고자 하는 학문적 관심에서 출발하여 사례연구 방법을 적용하여 행위통제의 관점에서 오픈소스 프로젝트들이 어떻게 관리되고 있는가 라는 문제를 연구하였다. 자료분석과 해석을 통해, 본 연구는 구체적인 사례들에 있어서 개별적인 차이들은 존재하지만, 전반적으로 오픈소스 프로젝트 관리에 있어 다양한 형태들의 행위통제가 이루어지고 있다는 사실을 확인하였다. 이러한 발견은 오픈 소스 프로젝트는 그 특성상 행위통제가 적용되기 어렵다고 보는 기존 일부 연구자들의 주장과 배치되는 내용이다. 오픈소스 프로젝트 관리에 관한 보다 더 포괄적인 학문적 이해를 위해서는 향후 결과통제와 자기통제까지 포함하는 보다 더 확대된 연구가 필요할 것으로 보인다.

For many years commentators have requested more active regulation of attorney ethics in international arbitration. Gradual deterioration of ethical standards in international arbitration will bring disrepute and, once its reputation is lost, it could take decades to rebuild confidence. The first reason for increasing unethical behavior is that there is no ethical code generally applied to all lawyers participating in international arbitration. A second reason might be that nobody is actively regulating attorneys in international arbitration. The first step to solve this problem is that major arbitration institutions should cooperate to enact a uniform code of conduct to be generally applied to all attorneys representing parties in international arbitration. Recently, IBA and LCIA prepared guidelines on party representation in international arbitration, and the guidelines will help attorneys follow uniform standardsof ethics. However, this will not be sufficient. There should be a regulating body to monitor attorney ethics and take sanctions against unethical attorneys accordingly. Arbitrators, who can see unethical behavior by attorneys from the closest distance, are the most appropriate regulating force rather than courts of arbitration seat or an attorney's licensing country. Of course, arbitrators don't have powers to withdraw or suspend an attorney's license, but they have powers to control attorneys'behavior within arbitration proceedings such as an allocation of fees and costs, barring the assertion of claims or defenses, drawing adverse inferences, or precluding the submission of evidence or testimony. Furthermore, arbitrators should be provided with such obligation as active control of attorney ethics. Even arbitration institutions should participate by imposing on an attorney who is a repeat offender a suspension from appearing in future arbitrations. Unethical behavior will decrease through concerted actions among arbitrational institutions to introduce a uniform code of conduct and to empower arbitrators for more efficient regulation of attorney ethics.
