As the growth of Internet business, many web sites have been developed their own Internet business strategies. Yet, many web sites have difficulties to make profit. In this paper, an economic model is developed to analyze web sites' quality and pricing strategies when they initiate their services as free services and develop advertising services and other charged services. By analyzing the economic model, optimal quality and prices was found. And by analyzing the optimal strategy, I found that web sites should properly decide their market share on initial customer. Finally, the importance of web sites' productivity to make profit is emphasized.

E-commerce is now widely used as the new business opportunity for most companies in Korea. The purpose of this study is first to find the attributes of the logistics service quality in e-commerce environment. We, then, try to find the relationships among service quality, customer satisfaction and repurchase intentions. The results of empirical study show that five attributes(responsiveness, empathy, reliability, accuracy and tangible) are identified as key factors of service quality. Customer satisfaction has also significant effect on repurchase intentions.

This paper examines internet shopping mall members' relationship quality and its antecedents variables. For this purpose, five types of membership customers' perceived variables, including convenience, product assortment, product information, shopping mall design, and service quality are proposed to affect customer satisfaction and consequently relationship quality. This study, which used data from customers of membership internet shopping malls, showed satisfactory data-fit to the proposed model and except product information hypothesis, supported all of research hypotheses. Also four types of membership customers' perceived variables(convenience, product assortment, shopping mall design, and service quality) take significant effect on customer satisfaction, and the satisfaction in turn have influence on relationship quality.

오늘날 시스템 사용에 있어 가장 큰 문제 중의 하나는 사용자의 요구를 잘 반영하지 못하는 데에 있다. 이러한 사용자의 요구를 반영하기 위해 기존의 많은 연구들은 기기나 서비스 자체에 초점을 두어 중요한 사용 품질요인을 규명하여 왔다. 그러나 모바일 컴퓨팅 서비스는 언제 어디서나 사용이 가능하기 때문에 사용 품질요인이 기존의 정보 시스템과는 다르게 나타나게 된다. 이러한 상황에도 불구하고 기존 연구들은 사용 환경을 고려하여 중요한 사용 품질요인을 도출하기 보다는 기기나 서비스 자체에 초점을 두어 연구를 진행하였다. 본 연구에서는 모바일 컴퓨팅 서비스를 대상으로 모바일 컴퓨팅 서비스 특성에 맞는 중요한 사용 품질요인을 도출하고자 하였다. 이를 위해 대표적인 모바일 컴퓨팅 서비스로 모바일 데이터 서비스를 선정하고 모바일 데이터 서비스 사용자를 대상으로 맥락 집중 인터뷰를 실시하였다. 인터뷰 실시 후 분석 결과, 모바일 컴퓨팅 서비스는 기존 정보 시스템에서 중요하게 나타났던 사용 품질요인과 다르게 나타났다.

Due to the rapid growth in automated testing and manufacturing systems, screening inspection becomes very attractive. In this paper, we investigate the effects of limited capacity on screening inspection using a surrogate variable. The model is developed under the assumption that the reprocessed and nonreprocessed items are produced by the same manufacturing process and therefore their quality characteristics are independently and identically distributed. Profit models are constructed which involve four price/cost components; selling price, cost incurred by imperfect quality, reprocessing and quality inspection costs. Methods of finding the optimal screening limits are presented, and a numerical example is given. Sensitivity analyses are also performed to study the effect of a process standard deviation on this model.

The trend toward globalization and competitive advantage is increasing the importance of international data communication . The more companies attempt to be globalized and competitive, the more critical the problems of the computer networks are. To improve computer networks in the business world, it is believed that the network shoud be approached from the viewpoint of service quality : we need to understand what network quality means to network users, those who use the network. The purpose of this study is to develop a dimension that captures the aspects of network quality that are important to network users. Many articles show that speed is very important factor in network systems. But the more important thing is that speed is just one of the factors contributing to network quality. It is suggested that a quality network meet nine dimensions : (1) speed (2) accessibility (3) connectivity (4) security (5) compatibility, (6) government restrictions (7) complexity (8) sustainability and (9) sharability.

This study demonstrates some major traits of digital contents as information, playfulness, individuality, as satisfaction and commitment, user behavior as use intention. To make an empirical analysis the study, it is hypothesized that traits of digital contents, relationship quality, and user behavior. The major finding of this study can be summarized as follows, traits of digital contents are positively affected by satisfaction in relationship quality and use intention. Theoretical implication of this study are as follows. First, users wanted to choice only needed information. Second, users recognized digital contents as a part of life. So, user's ability is very important in this environment. According to this, business related with or interested in digital contents must have developed digital contents in variety aspect. Users must have concerned using digital contents, also.

Purpose The purpose of this study is to identify the effects of users' perceived value of food delivery Apps and information quality on acceptance and intention to reuse of food delivery Apps. Design/methodology/approach This study made a design of the research model by integrating the factors of perceived value and information quality with the acceptance and continued usage of delivery Apps on the basis of the TAM (Technology Acceptance Model). Findings The results of this study suggests that perceived emotional value and monetary value, accuracy and timeliness of information have significant positive effects on usefulness and easiness of food delivery Apps. Meanwhile, both usefulness and easiness of food delivery Apps have significant positive influences on users' continually use intention. Furthermore, implications in terms of the findings of this study are discussed.

This study examines the foremost concerns related to most noted research performance index. The most popular and widely acceptable h-index underestimates the highly visible scientist, the middle order group, due to citation distribution issues. The study addresses this issue and uses 'Corrected Quality Ratio' (CQ) to check the implicit underpinnings as evident in h-index. CQ helps to incorporate the aspects of a good research performance indicator. This simple revision performs more intimately and logically to gauge the broader research impact for all groups and highly visible scientists with less statistical error.
