  • This study aims to examine the forming procedure of consumer satisfaction from Internet shopping experience. Many studies on the satisfaction have primarily focused on the examination of the antecedents of satisfaction along with the expectation-disconfirmation paradigm dominating the former studies. This study has built an Internet shopping expectation-disconfirmation model as to apply the expectation-disconfirmation into the condition of the Internet shopping. The summary of study represented in following. l. The expectation of risk and performance of benefit had a significantly positive effect on the perceived disconfirmation. In addition, an expectation of benefit and performance of risk had a significantly negative effect on the perceived disconfirmation. 2. A performance of risk and performance of benefit not only had a significantly indirect effect, but also a significantly direct effect on the consumer satisfaction. But expectation of risk and expectation of benefit had no significant direct effect on satisfaction. 3. Not only the perceived disconfirmation had a significant positive effect on satisfaction, but also an effect of the perceived disconfirmation on satisfaction(0.472) is larger than that of the performance of risk or performance of benefit. Meaning that, it is desirable for one to apply the expectation-disconfirmation model into the Internet shopping circumstances as much as the off-line markets.

  • This paper investigates the value of the expectation-confirmation model(ECM) of IT continuance in the internet shopping environments and attempts to expand the ECM with consideration of users diverse internet shopping factors and their preferences. Here, the extended ECM measures the users expectation-confirmation separately at the product, site and service levels, rather than treating it a single construct as measured in the original model. Further, AHP has been used for assessing the relative importance among the shopping factors, and the priority has been used for deriving weighted expectation-confirmation levels in the model. PLS analysis shows that there are significant differences in path coefficients between the ECM and a weighted ECM. This Indicates that users preferences among the diverse shopping factors need to be properly assessed to better understand the relationship between users expectation-confirmation and their continued usage behavior.

  • Purpose: This study was conducted to understand the degree of Internet addiction, Internet expectation and self-efficacy and we also wanted to elucidate the factors influencing this addiction among the high school students in Korea. Method: A total of 348 high school students in the Gyeoung-gi, Daegu and Gyeoung-buk area were surveyed in this study. Data collection was conducted through the use of questionnaires. Results: Internet addiction among high school students in Korea was relatively low. In the overall ratio distribution, however, the students who were classified as either addicted or at risk of addiction accounted were a high percentage of the subjects, 31%. A positive or negative relationship was found between internet addiction and the research variables. Multiple regression analysis revealed that the most powerful predictor of Internet addiction was Internet expectations. Conclusion: Using the above results, it would be necessary to develop an Internet addiction prevention program for adolescents. There should be a qualitative study in the future for an in-depth understanding of internet addiction of adolescents.

  • The purpose of this study was to investigate the relative effect of individual-, parents-, and game-related variables on game addiction. Totally, 1065 10 to 18-year-olds participated and completed questionnaires. Male students had more tendency to game addition than female students. No difference in the level of addiction, however, was appeared among elementary, junior-high, and high school groups, which means that many young children are already Same-addicted. More severely addicted children and adolescents showed higher level of impulsivity, more difficulties in communication with their parents, and more expectation of psychological gratification and interpersonal relationship through the internet games. The relative effects of these independent variables to game addiction were different among gender*school groups. Firstly, impulsivity was significant only in boys of elementary group. Secondly, for the junior-high group, communication with father and mother was important to boys and girls, repectively. Lastly, expected gratification from gaming itself mainly predicted high school students' game addiction, irrespective of gender. The findings of this study suggest that earlier intervention to young garners should be carried out. It is also indicated that parents' and teachers' role for guidance of the internet games would be different with children's gender and developmental stages.

  • IT의 발전과 더불어 금융권의 비대면 채널 역시 폭발적으로 증가되어왔다. 하지만 금융 시스템의 특성을 명확하게 반영한 규모 산정에 대한 모델의 부재로 인하여 예산 수립의 신뢰성 저하, 그리고 이에 따른 저가 수주 경쟁 등이 빈번하게 발생하였다. 이러한 규모 예측의 신뢰성 저하는 인터넷 뱅킹 시스템의 품질 저하로 이어져 금융 상품을 이용하는 고객에게 피해가 전해지고 있다. 따라서 본 논문에서는 기존 금융권에서 사용하는 규모 산정 기법의 두 종류인 FP 기반 규모 산정과 전문가 유추 기반의 규모 산정을 토대로 규모 산정 기법을 개선하여 보다 간편하고, 실제 금융 비대면 채널 수행 규모에 근접한 규모 예측 기법을 구축하고 이의 효용성을 회귀분석을 통하여 검증하였다. 그 결과, 기존 규모 산정 기법보다 실제 수행 규모와 상관관계 및 정확도가 증가된 인터넷 뱅킹 시스템을 위한 개선된 FP 기반 초기 규모예측 모델과 도구를 구축하였다.

  • This paper develops an integrative model for IT continuance in the internet shopping environments by integrating the expectation-confirmation and the switching cost factors. Using this model, in addition, this study investigates their differential effects on the mediating variables, such as user satisfaction, commitment, and trust which have been identified as antecedents of users' IT continuance intention. Results show that the product and service-related expectation confirmation factors and the relational switching cost factor can have greater impacts on users continuance intention than the web site design factors, and the financial and procedural switching cost factors. In particular, it is interesting to note that relational switching cost can lead users to more commitment, which is revealed as the strongest antecedent of their continuance intention to use a certain shopping site.

  • 인터넷 쇼핑몰의 수는 2004년 2월 현재 3,415개이며, 이는 2003년 동월대비 333개가 늘어난 것으로 10.8%의 증가를 보여주고 있다. 그러나 많은 기업들이 수익성 부족으로 어려움을 겪고 있는 실정이다. 이는 전자상거래를 이용하는 소비자들에 대한 연구와 조사 분석이 부족했음을 뜻한다. 지금과 같이 고객에 대한 체계적인 연구가 없이 개인적인 감각이나 세태의 추세에 의존하여 무분별하게 점포를 개설할 경우에 적자의 가능성은 더욱 높아질 것이다. 따라서 본 연구는 전자상거래의 한 영역인 기업-소비자간 인터넷 쇼핑몰을 중심으로 소비자의 기대-성과에 대한 차이를 보고자 하였다. 이에 따른 연구결과는 다음과 같다. 첫째, 인터넷 쇼핑몰 유형에 따른 고객만족요인의 유의적인 차이를 알아본 결과, 소비자 불안 인터넷 유용성만 쇼핑몰 유형에 따라 차이가 있는 것으로 나타났으며, 고객서비스는 인터넷 쇼핑몰 유형에 따른 기대-성과 차이가 나타나지 않았다. 소비자들은 소비자 불안에 대해 쇼핑몰의 유형에 상관없이 성과보다 기대가 높은 것으로 조사되었다. 특히, 기대-성과 차이에 있어서 종합형과 전문점에서는 개인정보유출이 가장 큰 차이를 보여주고 있는 반면에 중개형의 기능불안은 기대-성과차이가 가장 적은 것으로 조사되었다. 또한 인터넷 유용성에 있어서 기대-성과 차이를 알아본 결과, 전문형에서는 제품 정보 풍부, 정보 탐색비용 절감성이 가장 큰 차이를 나타내고 있는 반면에 중개형은 정보탐색 비용의 절감성이 가장 적은 차이를 보여주고 있다. 둘째, 고객서비스, 인터넷 유용성, 소비자 불안과 고객만족과의 관련성을 알아보기 위하여 회귀분석을 실시한 결과 고객 서비스, 인터넷 유용성, 소비자 불안은 모두 고객만족에 영향을 미치는 것으로 나타났다. 그리고 고객만족과 구전의도, 재구매 의도에 대한 관련성을 알아본 결과 고객만족은 구전의도, 재구매 의도에 모두 정(+)의 영향을 미치는 것으로 조사되었다. 3차원 영상으로 표현하여 보여주고, 환자에 관한 각종 정보와 진단정보 등을 신속하게 제공한다. 본 논문에서 제안하는 의료영상정보시스템은 초고속 정보통신 망을 통하여 원격의료시스템을 구축하는데 활용될 수 있을 것이다. 외 해수 중에서 생물입자 size 분포 보다 더 광범위한 분포와 다양한 환경(입자의 비중, 해상의 바람, 저질상태, 수심 등)에 의한 것으로 추정되었다.ents should be given this natural ground of proof.understanding with multiple, dynamic representations of the problem using visualization. The strategies used in making a plan were collecting data, using pictures, inductive, and deductive reasoning, and creative reasoning to develop abstract thinking. In carrying out the plan, students can solve the problem according to their strategies they planned in the previous phase. In looking back, the program is very useful to provide students an opportunity to reflect problem-solving process, generalize their solution and create a new in-depth problem. This program was well matched with the dynamic and oscillation Polya#s problem-solving process. Moreover, students can facilitate their motivation to

  • Location-aware networks are of great importance for both civil lives and military applications. Methods based on line-of-sight (LOS) measurements suffer sever performance loss in harsh environments such as indoor scenarios, where sensors can receive both LOS and non-line-of-sight (NLOS) measurements. In this paper, we propose a data association (DA) process based on the expectation maximization (EM) algorithm, which enables us to exploit multipath components (MPCs). By setting the mapping relationship between the measurements and scatters as a latent variable, coefficients of the Gaussian mixture model are estimated. Moreover, considering the misalignment of sensor position, we propose a space-alternating generalized expectation maximization (SAGE)-based algorithms to jointly update the target localization and sensor position information. A two dimensional (2-D) circularly symmetric Gaussian distribution is employed to approximate the probability density function of the sensor's position uncertainty via the minimization of the Kullback-Leibler divergence (KLD), which enables us to calculate the expectation step with low computational complexity. Moreover, a distributed implementation is derived based on the average consensus method to improve the scalability of the proposed algorithm. Simulation results demonstrate that the proposed centralized and distributed algorithms can perform close to the Monte Carlo-based method with much lower communication overhead and computational complexity.

  • Existing model houses have played an important role in allow the customers to choose apartment. As the information technology has been advanced (e.g. a high-speed internet available in unit), customers' personality and preference to the design of apartment and the purchasing pattern have been changed. Construction firms have introduced VR(Virtual Reality) model house (e.g. Quick Time Virtual Reality) to meet the customers' expectation and need. The reality-based QTVR model house does not provide enough quality to satisfy the customers' expectation. To complement the shortcoming of the QTVR model house, this study presents a web-based cyber model house developed by using Turntool and Javascript. The cyber model house allows to communicate between supplier and customer over the internet.
