When new information communication technologies(ICTs) have appeared, researchers and praticitioners have explored how to spread the technologies. In e-commerce, social commerce has been introduced recently and attempts to understand social commerce have proposed diverse research models. This study proposed a hypothetical model which integrates technology readiness(TR), technology acceptance model(TAM), and theory of planned behavior(TPB). Through PLS path modeling, we found that every hypothesis except social norm-intention path alone proved significant. This result means that integrated model is useful to understand the adoption of new ICTs including social commerce. Finally, based on the findings, suggestions for future research were discussed.

이 논문은 상위 단계 데이터-경로 합성에서 연산 스케쥴링과 자원 할당 및 배정을 동시에 고려한 통합적 접근 방법을 제시한다. 제안한 방법은 스케쥴링 되어있지 않은 데이터-플로우 그래프에 대해서 수행에 필요한 총 clock 스텝 수와 필요한 회로 면적을 동시에 최소화하는 데이터-경로 생성에 특징이 있다. 일반적으로, 연결선의 결정이 합성의 마지막 단계에서 이루어지는 기존의 방법과는 다르게, 우리의 접근 방법은 연산 스케쥴링과 연산의 연산 모듈 배정 그리고 변수의 레지스터 배정 작업을 동시에 수행하여 추가적인 연결선의 수를 매 clock 스텝마다 최적화(optimal) 시킨다. 본 논문은, 이 문제를 최소-비용의 최대-플로우 문제로 변형하여 minimum cost augmentation 방법으로 polynomial time 안에 해결하는 알고리즘을 제안한다.

In these days of severe changes in the environment and economic slump, it is indispensable for firms to cope with the environment effectively. This study is an attempt to investigate the mechanisms through which output sector munificence and dynamism affect distribution channel performances, such as, satisfaction, trust, and commitment. Especially, this study focus on moderating effects on distribution channel integration that has not been investigated in the past. For the purpose of empirical testing, 70 corporate channels, 120 contractual channels, and 100 conventional marketing channels have been selected and analyzed. According to the result from moderated regression analysis, munificence strengthens distribution channel performances, while dynamism weakens them. And integration reinforces the effects.

Recently route guiding system using GPS is spread widely. In the parking management system of complex mall, RFID is mainly used to control status of parking lots. However, in a case that a vehicle only with RFID tag enters into small market-populated district with service of parking lots, there is no parking route guiding system optimized with information of real tine status of parking lots and the system only with GPS can't provide a function of using real time status of parking lots. This paper proposes a location recognizing method of RFID tag object for parking control system to integrated several parking lots in the business district and database-linked route guiding system optimized for parking. The proposed location recognizing method makes the search of optimized parking route possible by abstracting decoding order of tag and antenna number and recognizing direction of tag linked with database. Ihe implemented system that is composed of RFID tag, reader, middleware, server, parking lot clients and mobile clients shows that the proposed method works well and it will be useful for integrated parking control system.

Using hybrid channel affords the benefits of achieving control through the direct channel and achieving flexibility through the indirect channel. However, using a hybrid channel also poses special challenges to a manufacturer, including the problem of managing multiple channel members with disparate goals and priorities. The purpose of this study is to enhance our understanding on the management of hybrid channel. We study marketing channels for fashion apparel to examine governance challenges and solutions of a hybrid channel. We have two objectives to fulfill that purpose. First, we aim to tie two largely separate research streams of salesforce management and marketing channel management together by examining both intrafrim governance and interfirm governance issues under one conceptual framework. Second, we aim to lay a ground work for rigorous further research on this topic by tying two major theoretical approaches of governance together under one conceptual framework. Our predictions were tested with data from the survey of apparel manufacturers and retailers. The analysis results support the predictions moderately.

In this paper, we propose effective integration and operation methods for environment-friendly smart home appliance which are applying hardware integration technology using high speed Ethernet network technology and software integration technology using RT middleware. We also describe the integration of distributed hardware device by using high speed Ethernet and software integration technology by using RT middleware. We implement the integration management system of environment-friendly smart home appliance applying high speed Ethernet and RT middleware technology.

현대 사회에서는 재난의 유형과 피해가 다양해지고 이에 따른 위험성이 증가하여 재난에 대응하기 위한 운영 및 관리의 필요성이 증가하고 있다. 특히 건축물의 대형화, 복잡화로 인하여 대규모 상업시설 및 다중이용시설은 실내 구조가 복잡하기 때문에 재난 발생 시 안전한 대피 경로를 파악하여 이동하는 것이 어려운 문제가 있다. 이에 본 연구에서는 재난 발생 시에 대규모 시설 내에서 이용자가 안전한 대피경로를 확인하고 이동할 수 있도록 지원하기 위한 통합관제체계 구축 방안에 대해서 연구하였다. 본 연구에서 제시하는 통합관제체계와 스마트폰 어플리케이션을 연계하여 재난 발생 시, 시설 이용자에게 안전한 대피경로를 안내함으로써 실내 공간에서의 대패를 지원할 수 있다.

This study shows a limit to attacks that the prevention system, which is used as the mutual third aggressive packet path between open heterogeneous networks and applies prevention techniques according to the trace like IP tracking and attack methods, can prevent. Therefore, the study aims to learn information of constant attack routing protocol and of the path in network, the target of attack and build a database by encapsulating networks information routing protocol operates in order to prevent source attack paths. In addition, the study is conducted to divide network routing protocols developed from the process of dividing the various attack characters and prevent various attacks. This study is meaningful in that it analyzes attack path network and attacks of each routing protocol and secure exact mechanism for prevention by means of 3D-Puzzle, Path, and Cube of the integrated security system which is an implementation method of integrated information protection for access network defense.

The purpose of this study was to examine the effect of an ICT based integrated dementia prevention program on vitality, fear of dementia, preventive behavior of dementia in the elderly using senior citizen centers. The experimental treatment was given an ICT based integrated dementia prevention program for the preventive behavior of dementia for 12 sessions over 6 weeks by the one group pretest-posttest design. Data analysis was Paired t-test, Pearson's correlation coefficient. The level of vitality and preventive behavior of dementia improved, and fear of dementia level decreased for these elderly using senior citizen centers. Therefore, it is recommended that the integrated ICT based dementia prevention program be utilized in clinical settings to prevent dementia among senior citizens using senior centers.
