This study investigated the factors that facilitate knowledge creation of team with the aspect of knowledge management. We considered two characteristics which are team members' psychological characteristics (achievement needs and conflict emotion) and knowledge network characteristics among team members (internal cohesion and external bridging) and verified the relationship between these characteristics and team performance. Furthermore, we examined whether these characteristics have a different effect on team performance according to the mastery climate. This study performed a survey targeting team members in knowledge based firms and 376 final surveys to be used as a sample in this study. The result showed that team members' psychological characteristics and knowledge network characteristics among Team members have an influence on team performance significantly. In addition, the master climate moderated the relationship between team members' psychological characteristics and team performance.

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.

Human Fen1 protein (hFen1) plays an important role in Okazaki fragment processing by cleaving the flap structure at the junction between single-stranded (ss) DNA and doublestranded (ds) DNA, an intermediate formed during Okazaki fragment processing, resulting in ligatable nicked dsDNA. It was reported that hChlR1, a member of the cohesion establishment factor family, stimulates hFen1 nuclease activity regardless of its ATPase activity. In this study, we found that cohesion establishment factors cooperatively stimulate endonuclease activity of hFen1 in in vivo mimic condition, including replication protein-A-coated DNA and high salt. Our findings are helpful to explain how a DNA replication machinery larger than the cohesion complex goes through the cohesin ring structure on DNA during S phase in the cell cycle.

Group features such as group cohesion and consistency on appropriation(COA), which have been constructed through social interactions, should be noted for characterizing online game, especially, clan based massively multi-players online game (MMOG). This study attempted to identify the relationship between group characteristics and users' effectiveness of MMOG considering group experience. For this purpose, a research model was suggested: group cohesion and COA are variables for explaining group features, perceived use control is a variable for individual competency of playing MMOG, and perceived winning and perceived enjoyment are dependent variables. Moreover, group experience was included as a moderating variables for two relationships, group cohesion-preceived winning and COA-perceived winning. For the validation of this research model, 100 users for Sudden Attack which is one of very well known MMOG games were surveyed by questionnaires. Before survey, they were grouped into 10 teams and were played over ten times by team for perceiving group consciousness. In result, most hypotheses were statistically supported except the relationship between group cohesion and perceived winning.

This study explored the elements that affect team achievements in virtual environments. In this study, consideration was given to the role of group dynamics in facilitating productive interaction. We aspired to reveal the mechanisms of group dynamics and examined how group dynamics affected team achievements in virtual environments. The empirical study was performed with undergraduate students enrolled in an e-learning course. In collaboration with other majors, students executed team projects and managed project issues in forums or chat rooms. The results of the empirical study indicated that leadership, creative friction, and group cohesion (components of group dynamics) had positive relationships with team achievements. The findings confirmed that addressing creative conflict is a method to improve team performance and that leadership is a key factor in project teams.

Reinforced twice than width of foundation with SIC under steel piles drived in cohesion soil and in the coal-limestone which heavily fractured. To analyze behaviour characteristic of steel piles, load transfer test was performed to steel piles attached with strain gauges to axial direction. After it passed 49days, dynamic load test was performed to set-up effect of steel piles bearing capacity. The results of test were compared to each other. According to the results, as the skin friction of steel pile was on the same condition, end bearing capacity of steel piles established on SIC solid of cemented milk in cohesion soil was three times than steel piles established on SIG solid of cemented milk in heavily fractured coal- limestone. After piles were driven and passes 49days, in case of piles on SIG solid of comented milk in cohesion soil the increaes of allowable bearing capacity was 442.9% and allowable bearing capacity of piles on SIG solid of cemented milk in heavily fractured coal-limestone increased 22.4%.

최근 들어 산업부산물인 저회를 지반 매립재로 활용하려는 연구가 활발하게 진행되고 있다. 본 연구에서는 국내 5개 사에서 채취된 저회와 풍화토 혼합하여, 3가지 저회의 혼합비 (30%, 50%, 70%)에 따른 다짐실험, CBR 실험 및 삼축 압축실험 등이 수행되었다. 실험 결과, 저회를 혼입한 혼합토의 CBR값은 20을 상회하였으며, 소성을 보이지 않아 성토재료로 사용이 가능할 것으로 평가되었다. 혼합토에 사용된 저회의 역학적 성능이 풍화토보다 우수하므로, 혼합비가 증가할수록 혼합토의 CBR값은 뚜렷한 증가를 나타내었다. 그러나, 배합후 입자배열에는 큰 영향을 주지 못하므로, 혼합비에 따른 내부마찰각 및 점착력의 변화는 뚜렷하게 평가되지 못했다. 저회는 시료 자체의 강성이 있으므로, 지지력이 풍화토에 비하여 크게 평가되었으며, 성토재료로서의 활용할 수 있음을 실험적으로 규명하였다.

Background: The purpose of this study was to examine the cohesions status of the coordination within response teams in the emergency response team (ERT) in a refinery. Methods: For this study, cohesion indicators of social network analysis (SNA; density, degree centrality, reciprocity, and transitivity) were utilized to examine the coordination of the response teams as a whole network. The ERT of this research, which was a case study, included seven teams consisting of 152 members. The required data were collected through structured interviews and were analyzed using the UCINET 6.0 Social Network Analysis Program. Results: The results reported a relatively low number of triple connections, poor coordination with key members, and a high level of mutual relations in the network with low density, all implying that there were low cohesions of coordination in the ERT. Conclusion: The results showed that SNA provided a quantitative and logical approach for the examination of the coordination status among response teams and it also provided a main opportunity for managers and planners to have a clear understanding of the presented status. The research concluded that fundamental efforts were needed to improve the presented situations.

The purpose of this study is to develop the guideline of the physicochemical and mechanical properties evaluation for silicone gel filled breast implants. First of all, the use and development status for silicone gel filled breast implants were investigated, and then, standard and criteria about performance evaluation established by the international organizations such as ASTM, FDA guidance and ISO were examined. To evaluate the mechanical properties, data research and testing for breaking strength, elongation, tensile set, joint intensity, silicone gel cohesion, weight loss from heating, static rupture resistance, impact resistance test, fatigue test, and gel bleed were performed. On the other hand, to evaluate the physicochemical properties, volatile matter, extent of cross linking, heavy metals, and extractable were analyzed. In this study, results for general function, mechanical properties and physicochemical properties were examined and reviewed for the accordance with international standard, and objective and standardized guideline was provided.
