This paper was done as an exploratory study aiming to identify the relationship between small group characteristic factors and perceived performance in the Village Development Committee (VDC) in Saemaul Undong project in Laos. The data were gathered from 166 members in 17 VDCs in Vientian province, however 135 questionnaires were used in analysis. Structure Equation Model was applied in the analysis with Amos 21. The major finding of this study were as follows; firstly decision making was more influenced by task cohesion than social cohesion, secondly organizational citizen behavior was influenced by both task cohesion and social cohesion. However, social cohesion had more influence than task cohesion, thirdly the VDC members learned their technical knowledge from decision-making process, and influenced to their perceived performance level and to VDC sustainablity, and fourthly in overall, committee members implemented their jobs based on task-oriented.

팀 응집성은 양날의 검처럼 정적 부적 효과가 있다는 논쟁에도 불구하고, 실증 연구들은 팀 응집성의 긍정적 측면을 부각하였다. 본 연구는 팀 응집성을 관계를 강조하는 사회적 응집성과 과업을 강조하는 과업 응집성으로 구분하고, 창의적 긴장에 의해 창출되는 기술혁신 성과를 결과변수로 본다면, 팀 응집성의 정적 부적 효과에 대한 논쟁을 실증적으로 규명할 수 있다고 보았다. 또한 응집성은 동질성을 강조하므로, 다양한 사고를 촉진시키는 팀 창의성 지원 풍토는 사회적 응집성의 부적 효과를 완화시키고, 과업 응집성의 정적 효과를 강화시킬 것으로 보았다. 205개의 신제품개발팀들을 대상으로 설문조사한 결과, 기술혁신 성과에 대해 사회적 응집성의 부적 영향(${\beta}$=-.19, p<.01), 과업 응집성의 정적 영향(${\beta}$=.18, p<.05), 사회적 응집성과 팀 창의성 지원 풍토의 정적 상호작용효과(${\beta}$=.14, p<.10) 및 과업 응집성과 팀 창의성 지원 풍토의 정적 상호작용효과(${\beta}$=.16, p<.05)가 있는 것으로 나타났다.

The purpose of this study is to investigate the effect of wives' demographic variables, the family cohesion and adaptability perceived by dual-career wives on household task performance. The subject of this study were 391 employed professional wives working in seoul. Using the questionnary, the data was obtained and the data was analysed by percentile, frequency, ANOVA, multiple regression. The results were as follows. 1) the family cohesion and adaptability scores showed a little higher than those of previous research. Number of children, age of the youngest child and family pattern were statistically significant in the family cohesion, number of children and family pattern were statistically significantly in the family adaptability. 2) The division of housework by family members was influenced by the family adaptability and family pattern. The family cohesion was a significant determinant of the division of housework by husband. The standard of housework was influenced by wives' age, the family cohesion and a housework time.

The purpose of this study was to investigate the characteristics for cohesion in the narratives of fluent aphasics. Ten fluent aphasics and ten normal adults matched chronological-age and education level with aphasics participated in this study. Story retelling task was given to the participants individually. And all narratives they produced were recorded and transcribed for analysis. The frequency of cohesive markers and the rate of accuracy were analyzed. The result were as follows; (1) The fluent aphasics used cohesive devices significantly less than the normal adult group, and the rate of accuracy of cohesive devices used was lower than the normal adults. (2) Both groups used lexical cohesion more than pro-forms and ellipsis, and the difference of two groups was larger in lexical cohesion than pro-forms and ellipsis. (3) The fluent aphasics used lexical cohesion more accurately than pro-forms and ellipsis but the normal adults used all three cohesive markers accurately. The difference of two groups was large in pro-forms and ellipsis.

스타트업은 공동의 목표를 가지고 소수의 전문가들이 모여서 한정된 자원을 이용하여 창의석인 성과를 달성하는 소규모 조직이다. 실제 스타트업 환경에서 빈번하게 발생하는 갈등을 과업 갈등과 관계 갈등으로 구분하고, 팀워크에 미치는 영향을 긍정과 부정으로 나누어 연구 모형을 설계하였다. 팀워크의 요소로는 의사소통, 협업, 업무조정과 응집력을 설정하였으며 최종적으로 스타트업 팀의 성과에 미치는 개별 구성요소의 영향력을 검증하였다. 스타트업 팀 142개를 대상으로 설문조사를 통해 데이터를 수집하고 PLS를 이용하여 통계적으로 분석하였다. 구조모형 검증 결과, 과업 갈등은 팀워크에 긍정적인 영향을, 관계 갈등은 팀워크의 일부 요소에 부정적인 영향을 미치는 것으로 나타났으며, 팀워크 중 의사소통을 제외한 협업, 업무조정, 응집력은 팀의 성과를 높이는 효과를 가지고 있는 것으로 분석되었다. 이 결과를 바탕으로 스타트업 조직의 리더 또는 관리자와 구성원을 위한 조직 운영 방안을 제시하고, 이론적 기여점을 서술하였다.

This study aims at analyzing the relationship between team characteristic and innovation performance. The mediating effect of creative climate on the team characteristic and innovation performance is also measured. Based upon literature review, individual creative characteristics, team diversity, team cohesion, task characteristics are presented as antecedents of team characteristic. Creative climate affects the creative behavior and innovative performance. Creative climate is measured as the Team Climate Inventory (TCI) proposed by Anderson & West (1998) including goal, participative-autonomy and innovative-support. Data were collected from 186 survey responses (54 Teams) out of total 462 (69 teams) from the R&D department of a major ICT firm in Korea. Empirical results show the diversity, cohesion, job characteristic, individual creative characteristic have a positive effect on the creative climate and innovation performance. The participative-autonomy climate factor appears to mediate the relationship between team characteristic (diversity, cohesion, job and individual characteristics) and innovation performance. However, the mediating effects of goals and innovative-support factors were not significant statistically. It was confirmed that the organization can contribute to improve the team innovation performance by facilitating a autonomy and participative climate as well as fostering the team characteristic.

Today's organizations make every effort to achieve effective knowledge management. under the recognition that knowledge is a powerful. competitive weapon. For knowledge management to be successful, however, not only should knowledge be voluntarily offered by organizational members but also the organizational ownership of knowledge be perceived among members. In this regard. this study explores antecedent factors of organizational ownership of knowledge based on the extension of previous studies. The analysis of two hundred and fifty-five survey data indicates that cohesion of department or team, propensity to share, and task interdependence are significantly related to organizational ownership. The relationship turns out to be stronger with tacit knowledge than with explicit knowledge. Some suggestions are proposed for enhancing effective knowledge management.

In this paper we back-analyze a failure event of a 9 m high concrete cantilever wall subjected to earth loading. Granular soil was deposited into the space between the wall and a nearby rock slope. The wall segments were not designed to carry lateral earth loading and collapsed due to excessive bending. As many geotechnical programs rely on the Mohr-Coulomb (MC) criterion for elastoplastic analysis, it is useful to apply this failure criterion to the concrete material. Accordingly, the back-analysis is aimed to search for the suitable MC parameters of the concrete. For this study, we propose a methodology for accelerating the back-analysis task by automating the numerical modeling procedure and applying a machine-learning (ML) analysis on FE model results. Through this analysis it is found that the residual cohesion and friction angle have a highly significant impact on model results. Compared to traditional back-analysis studies where good agreement between model and reality are deemed successful based on a limited number of models, the current ML analysis demonstrate that a range of possible combinations of parameters can yield similar results. The proposed methodology can be modified for similar calibration and back-analysis tasks.
