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.

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.

This study suggests new perspective of interorganizational communication. The importance of communication quality is increasing because it affects performance of marketing channels. In perspective of information exchange, communication quality consists of accuracy, availability, timing, and credibility. In research model, the antecedents of communication quality adopt willingness of information sharing and capability of efficient communication. To examine effects of communication quality on channel performance, research model includes relation of communication quality and conflicts. For empirical test, relation of PC makers and their dealers is decided as a focal dyad. Findings indicate that overall hypotheses are supported except the relation of willingness of information sharing and communication quality.

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.

This paper studies the effects of wavelength conversion on self-healing optical networks. We examined the effects of wavelength conversion capability on the backup routing and the spare wavelength utilization. The efficiency of spare wavelength utilization is proportionally increased as the wavelength conversion capability increases, different from the call blocking probability for which about 30% of wavelength conversion capability shows nearly the same performance as full wavelength conversion capability. The spare resource utilization efficiency can be improved by using alternate routing and wavelength assignment algorithms.
