Although previous studies on social commerce have provided much insight, more studies in the perspective of social network are needed because social commerce happens within online communities or virtual groups, where buyers connect and interact with each other by sharing information. So, the purpose of this study is to investigate how transactive memory as network characteristic can affect social commerce behavior through social support and relationship quality. We verified the relational effect among social support, relationship quality, and social commerce intention in the Korean market context. Moreover, we found transactive memory capability also played an essential role in the field of social commerce. Specifically, we found consumer's transactive memory capability plays a significant moderating role in the relation between social support and relationship quality.

군 통신 쉘터는 내부에 통신 및 환경장비를 탑재하여, 네트워크 중심전에서 다양한 무기체계들의 통합적인 전투력 발휘를 위해 요구되는 정보의 송/수신 기능을 실시간 보장하고 전술환경의 생존성을 극대화시키는 장비이다. 쉘터 내부에 다양한 통신용 장비가 탑재되기 때문에 외부로부터의 전자기 공격에 대한 차페 성능을 반드시 보장해야한다. 본 연구에서는 데이터 마이닝 기법(서포트 벡터 머신)과 통계적 품질관리 기법(공정능력분석)을 이용하여 군 통신용 쉘터에서 차폐성능이 안정된 지점을 탐색하는 연구를 진행하였다. 안정된 지점의 탐색을 위하여 45대 쉘터의 EMI 차폐효과 측정데이터를 활용하였다. 먼저, 차폐효과가 안정되었다고 판단할 수 있는 기준을 세우고 서포트 벡터 머신으로 해당 기준에 부합하는 측정 포인트 집단과 그 외의 집단을 분리, 이 두 집단을 분류할 수 있는 분류 하이퍼플레인을 작성하였다. 그리고 공정능력분석을 이용하여 차폐효과 측정 데이터를 분석, 공정능력지수가 높은 측정 포인트와 서포트 벡터 머신의 하이퍼플레인으로 분류한 측정 포인트를 상호 비교함으로써 분류된 측정 포인트의 타당성과 차폐효과가 안정된 정도를 분석하였다. 분석 결과, 24개의 측정포인트에서 안정된 차폐 성능을 보유하고 있음을 확인하였다.

The purpose of this study was to examine the effects of small-group discussion and panel discussion as teaching and learning methods on college students' competencies of communication, problem-solving and leadership in a general education course. Participants were 52 college students, and they participated in the 13-session lessons. The data from questionnaires collected before and/or after the experiment were analyzed using a paired t-test and percent. The results were as follows. First, each 'total' competency in communication, problem-solving and leadership was increased statistically significant after the experiment. Second, in subdomains of each key competency, 'directed communication' and 'understanding the perspective of others' in communication, and 'divergent thinking', 'decision-making' and 'assessment' subdomains in problem-solving, and all subdomains in leadership were increased statistically significant after the experiment. Based on the results and students' opinions about discussions, the education implications for small-group discussion and panel discussion were discussed.

본 연구는 경로구성원의 관계가 단기적인 관점에서 장기적인 관점으로 전환되는 시점에서 경로구성원간 의사소통 질의 중요성을 확인하기 위하여 진행되었다. 과거의 영향전략 연구가 경로구성원의 힘-의존 관계에서의 불균형 관계에 주로 초점을 맞춘 반면, 의사소통 질이라는 개념을 도출하여, 관계적인 경로구성원의 의사소통 측면을 고려하였다. 기존 연구에서 다루어지고 있는 의사소통 질은 경로구성원간에 전달되는 정보의 정확성, 적시성, 유용성, 신뢰성이 확보된 것을 의미한다. 연구모형에서 의사소통 질의 선행요소로서 정보공유 의지, 정보제공 능력을 도입하였고, 의사소통 질의 성과를 검토하기 위하여 갈등수준과의 관계를 점검하였다. 실증은 PC제조업체와 대리점의 관계를 대리점의 관점에서 진행하였다. 결과는, 대체로 기대와 일치하게 나타났으나, 의사소통 질에 대한 정보공유 의지의 영향은 직접적으로 나타나기 보다 정보제공 능력을 경유하여 간접적으로 전달됨을 발견하였다.

Purpose: In this logistics disturbance period, this study conducts research of distribution and logistics firms in Korea. The purpose of this exploratory research is to analyze global competitive capability influence on business performance. And give managerial implications and contribute to academics. Research design, data, and methodology: This research empirically analyzes the relationship between global competitive capability and business performance. As for business performance this research considered non-financial performance and measured with business performance fulfillment. As for antecedent variables, this research measured three global competitive capability constructs; preparation, utilization, intensive capability. And each construct includes two capability concepts. This study used 2,316 executing direct export distribution and logistics industry firmsfrom KOTRA's GCL data. This research used frequency analysis, reliability analysis, correlation analysis, and step-wise regression analysis by SPSS26. Results: The result shows that all the variables except export infra showed statistically significant. As results show, mid/long strategy & global mind of preparation capability, both communication and marketing of utilization capability and market strategy and product/goods/service of intensive capability give a positive influence on business performance fulfillment. Conclusions: Based on the results, this research provide implication for practical management, contribution to academic, and suggestion for feature research.

Construction industry recognizes the necessity to manage is business from viewpoint of processes, and consider developing, evaluating and improving standard processes as important managerial target. SW-CMM provides basic framework for this process management. However, appropriate tailoring and adjustment are essential for SW-CMM concept to be applied to construction business. SW-CMM makes construction manager understand the capability of business process, based on which the priority of process improvement is judged. The capability is prescribed by common features. This paper introduces the basic frame for diagnosing construction business processes with SW-CMM, and presents the case study of analysing processes focusing on communication management.

In this paper, we propose an efficient architecture for a high-speed cell concentrator/distributor(HCCD) in an ATM(Asynchronous Transfer Mode) switch and by analyzeing the simulation results evaluate the performance of the proposed architecuture. The proposed HCCD distributes cells from a switch link to local processors, or concentrates cells from local processor s to a switch link. This design is to guarntee a high throughput for the IPC (inter-processor communication) link in a distributed ATM switching system. The HCCD is designed in a moudlar architecture to provide the extensibility and the flexibility. The main characteristics of the HCCD are 1) Adaption of a local CPU in HCCD for improving flexibility of the system, 2) A cell-baced statistical multiplexing function for efficient multiplexing, 3) A cell distribution function based on VPI(Virtual Path Identifier), 4) A bypassing capability for IPC between processor attached to the same HCCD, 5) A multicasting capability for point-to-multipoint communication, 6) A VPI table updating function for the efficient management of links, 7) A self-testing function for detecting system fault.

이 논문에서는 광통신망에서 광파장 변환 능력이 통신망 복구 성능에 미치는 영향을 분석한다. 기존의 연구에서는 그물망 형태의 광통신망에서 약 30% 정도의 광파장 변환 능력이 제공된다면 Call Blocking 확률의 측면에서 100%의 광파장 변환 능력을 가질 때와 거의 같은 정도의 성능을 나타낸다고 알려져 왔다. 그러나 이는 정상적인 광파장 채널을 대상으로 하였을 때의 결과이고, 복구를 위한 예비 경로 및 예비 광파장을 포함한 복구 성능에 대한 광파장 변환 능력의 영향은 충분히 분석되지 않고 있다. 본 논문에서는 광파장 변환 능력이 예비 광파장의 이용 효율 면에서 망 복구 성능에 미치는 영향을 분석하였다. 실험 결과는 광파장 변환 능력과 복구를 위한 예비 광파장의 이용 효율성은 서로 비례하는 것으로 나타나, 정상적인 광파장 채널만을 대상으로 했던 기존 연구 결과와는 다름을 알 수 있다.
