일찍이 제품흥미나 중요성 대신 관여(involvement)의 개념이 소개된 이래로 마케팅과 소비자 행동 분야뿐 아니라 의류학분야의 여러 연구에서 관여는 구매자의 행동을 이해하는데 중요한 변수로 이해되어왔다. 그러나 관여의 개념은 의류제품의 특수성으로 인하여 변인이 조작적으로 정의되는 과정에서 의복관여, 유행관여, 패션관여 등의 용어가 혼용되어 왔다. 이러한 경향은 선행연구와 후행 연구의 연계성이라는 측면에서 “의복관여”라는 변수를 도입한 연구들의 해석에 많은 어려움을 주어 왔다. (중략)

This study has investigated the effects of relieving and promoting factors on dissolution intention under the condition of low commitment buyer-seller relationships. Based on intensive literature reviews, eight alleviating factors (dependence, cooperation, communication, relational norms, transaction specific investments, relationship termination costs, satisfaction, and trust) and five promoting factors (opportunism, conflict, goal incongruity, attractiveness of alternatives, and unfairness) were included. A total of thirteen hypotheses were testee using data collected from a dining franchising system. Among 300 collected, 79 cases of low commitment buyer-seller relationships were analyzed. The results showed that eight out of thirteen hypotheses were supported. But five hypotheses related to the variables of cooperation, transaction specific investments, relationship termination costs, attractiveness of alternatives, and opportunism were not supported. following a detailed presentation of the analysis results, the paper concludes by discussing the academic and managerial implications of the findings.

The advent of the Internet and development of information technologies have changed the environment of doing business. Accordingly, they expect that the relative importance of electronic commerce in the business becomes growing more and more. Among the areas of electronic commerce, B2B marketplaces that play the roles of linking buyers and suppliers take the important place. This study examines requirements for activating domestic B2B marketplaces by analyzing the literature and the status of the marketplaces. For the analysis, evaluation factors that belong to one of the four categories (i.e., Information step, Agreement step, Settlement step, and the rest) are selected. Results of the study suggest the following activation requirements for domestic B2B marketplaces : 1. Enforcement of services for the Agreement and Settlement steps. 2. Supporting multinational languages. 3. Diversification of income sources. 4. Standardization. 5. Integrating main systems. 6. Satisfying the necessities of buyers and suppliers.

This study introduced the new technologies that are expanding the realm of electronic commerce to the Internet and small business. Each of the key components of electronic commerce(contracts, signatures, notaries, payment systems and adult trails)are supported in the new electronic commerce. Electronic commerce is more than just handling purchase transactions and funds transfers over the internet. Despite Electronic commerce's past roots in transactions between large corporations, banks, and other financial institutions, the use of the internet as a way to bring Electronic commerce to the individual consumer has led to shift in viewpoint. Over the past few years, both the press and the business community have increased their focus on Electronic commerce involving the consumer Effective payment system should be established for the internet commerce. In this study, we examined the current development and application of Electronic payment system. Two different payment systems are used and under application. One is IC-card type of payment system which has gained popularity in England, Hong-Kong, and many other countries as a substitution of cash. The other type of payment system is e-cash, which is used more conveniently for the payment through internet. The question of which method is better fitted for the internet commerce should be evaluated in the view of cost and benefit since the associated technology is still under evolution. This study conducted a study on Secure Payment Method & Security Technology of Electronic Commerce

Digital watermarking technique for copyright protection and prevention of illegal copy and distribution can provide the reliable transaction to both buyer and seller in e-commerce through the cryptographic protocol such as 'Buyer-seller watermarking protocol'. Recently there has been researched about some cryptographic protocols for watermarking system but there has no yet mentioned about the implementation of practical watermarking technique in protocol. This paper presents the watermark embedding technique based on POCS in buyer-seller watermarking protocol. The proposed method designs the robust convex set based on EZW and the invisible convex set using PSNR and then projects into two sets until the convergence condition is satisfied. Experimental results verified that BER of watermark that is embedded by the proposed method has lower 0.02-0.10 than BER of the conventional method.

This study aims to develop a predictive model to suggest a used sales price to sellers and buyers when trading used tablet PCs. For model development, we analyzed the real used tablet PC transaction data and additionally collected detailed product information. We developed several predictive models and selected the best predictive model among them. Specifically, we considered a multiple linear regression model using the used sales price as a dependent variable and other variables in the integrated data as independent variables, a multiple linear regression model including interactions, and the models from stepwise variable selection in each model. The model with the best predictive performance was finally selected through cross-validation. Through this study, we can predict the sales price of used tablet PCs and suggest appropriate used sales prices to sellers and buyers.

Impulsive buying has been considered as one of the major negative shopping behavior. Indeed, it happened more easily in the Internet shopping area. This study attempted to examine the influence of personality on the compulsive buying tendency of college students who are actively shopping clothing and apparels through Internet. The results of the current study showed that there are four types of compulsive buying tendency such as 'diversion', 'no-plan', 'buyer/ product-stimuli' and 'promotion-stimuli.' It seemed that personality such as sensation seeking, need-for cognition, self-esteem, and face-consciousness had influence on the impulsive buying tendency. More specifically, people with low self-esteem and high face-consciousness tend to have more impulsive buying tendency. The relationship between each of the impulsive buying tendency and personality had been discussed.

본 연구에서는 분산화된 공급체인상황하에서 효과적인 조정 메커니즘으로 제시되고 있는 공급체인계약의 유형들 중에서 서적, 음반 및 컴퓨터 산업등에서 주로 사용되는 반품계약(Return Policy)에 대한 동적 시뮬레이션 모형을 구축하고, 반품비율 및 환매가 등의 계약 파라미터들이 모형의 성과에 미치는 영향과 구매자의 판매노력 및 판매자의 위험성향이 고려되는 상황하에서 반품계약의 효과성이 어떻게 바뀌는지를 분석하고자 한다. 연구의 목적은 판매노력 및 위험성향과 같은 요인들이 반품계약의 효과성에 어떠한 영향을 미치는지를 분석하는 것이며 부가적으로는 공급체인계약에 대한 동적시뮬레이션 모형을 구축하고 연구함으로서 최근 관심이 증대되고 있는 시스템다이내믹스 접근이 공급체인관리 분야의 연구에 유의하게 기여할 수 있음을 제시하고 향후 연구를 위한 기반을 다지고자 한다. 연구결과 반품계약을 시행하는 경우에 공급체인의 성과가 높으며, 반품계약과 더불어 판매자의 판매노력이 고려되는 경우에는 성과가 더욱 향상되었다. 또한 판매자가 위험회피성향을 가진 경우에는 공급체인성과가 감소하였다.
