The purpose of this study was to understand fashion product consumers' relationship dissolution by considering the characteristics of customer behavior and examining the connection between the main variables. The survey was conducted on 623 women over 20 years old who had experienced relationship dissolution or problems with regular fashion stores in the areas of Seoul and Kyungki in September 2005. The SPSS 12.0 package and Amos program were used to analyze the data. The results of this study were as follows: First, service recovery justice of a fashion store, interactional justice, distributive justice, and procedural justice had effects on encounter satisfaction. Furthermore, encounter satisfaction influenced relationship dissolution behavior, voice, exit, loyalty, neglect via overall satisfaction. Second, there were differences in relationship dissolution behavior according to consumer loyalty and switching costs.

The design and development procedures of SF6 gas circuit breakers are still largely based on trial and error through testing although the development costs go higher every year. The computation cannot cover the testing satisfactorily because all the real processes arc not taken into account. But the knowledge of the arc behavior and the prediction of thermal plasmas inside SF6 interrupters by numerical simulations are more useful than those by experiments due to the difficulties to obtain physical quantities experimentally and the reduction of computational costs in recent years. In this paper, in order to get further information into the interruption process of a SF6 self-blast interrupter, which is based on the combination of thermal expansion and arc rotation, gas flow simulations with a CFD-arc modeling are performed during the whole switching process such as high-current period, pre-current zero period, and current-zero period. Through the complete work, the temperature of residual arcs as well as the breakdown index after current zero should be a good criterion to predict the dielectric capability of interrupters.

The traditional media ecosystem is facing major changes with the expansion of over-the-top (OTT) services. While the percentage of people cutting the cord has already exceeded the percentage of people subscribing to pay TV services in the United States, due to the unique characteristics of the Korean market, it is uncertain whether the cord-cutting trend will have an impact on the Korean media industry despite of the advantages of OTT services. Accordingly, this study has directly determined the beneficial and sacrificial factors of switching to OTT services, as well as the personal and external influences behind the Korean OTT service users' intention to switch. To achieve this, the Value-based Adoption Model (VAM) was used to measure the benefits of OTT services with regards to their content and systems, as well as measure the financial and procedural switching costs of cord-cutting; further, personal innovativeness and consumers' social image were added as external variables. The results of this study showed that consumers take the content and system quality of OTT services and procedural switching costs and into consideration, and that their intention to switch was based on social image. These results could serve as data for consumer analysis regarding the expansion of OTT services into the Korean media industry, and also provide the strategic basis for preparing for sudden changes that may occur in the media ecosystem due to cord-cutting.

We consider the development of an integer programming model and algorithm for the ATM switching node location problem. There are two kinds of facilities, hub facilities and remote facilities, with different capacities and installation costs. Each customer needs to be connected to one or more hub facilities via remote facilities, where the hub(remote) facilities need to be installed at the same candidate installation site of hub(remote) facility. We are given a set of customers with each demand requirements, a set of candidate installation sites of facilities, and connection costs between facilities, We need to determine the locations to place facilities, the number of facilities for each selected location, the set of customers who are connected to each installed hub facilities via installed remote facilities with minimum costs, while satisfying demand requirements of each customer. We formulate this problem as a general integer programming problem and solve it to optimality. In this paper, we develop a branch-and-cut algorithm with path variables. In the algorithm, we consider the integer knapsack polytope and derive valid inequalities. Computational experiments show that the algorithm works well in the real world situation. The results of this research can be used to develop optimization algorithms to solve capacitated facility location problems.

Purpose: The purpose of this study was to examine the effect of patient perception of the switching cost and negative word of mouth on revisit intention of patients in out-patient departments (OPDs) of general hospitals. Method: The participants were 306 patients in general hospital, selected through convenience sampling. Data were collected using a structured questionnaire and analyzed using descriptive statistics, Spearman correlation coefficient, and logistic regression with SPSS Win. Results: Relational switching cost was positively correlated with revisit intention (r=.58, p=<.001), but not financial switching cost or procedural switching cost. Negative word of mouth was negatively correlated with revisit intention (r=-.22, p=<.001). The significant predictors influencing revisit intention in patients was relational switching cost. Conclusion: The findings of this study suggest that hospital and nursing managers should seek to bolster perceptions of switching costs and negative word of mouth, which subsequently increases revisit intentions in small hospitals located in the country as well as urban large hospitals.

The purpose of this research is to investigate the factors that impact customer satisfaction and loyalty in mobile payment services. Specifically, this research (1) studies the influence of company reputation on customer satisfaction and loyalty, (2) examines service quality dimensions that increase customer satisfaction, and (3) assesses switching barriers as moderators in influencing customer loyalty. Findings of this empirical research reconfirm the point of view that company reputation, service quality, and switching barriers are crucial for customer satisfaction in mobile payment services. The research methodologies that were used to verify the hypothesis in this study included customized surveys and structural equation modeling. The results demonstrated that company reputation significantly affects customer satisfaction and loyalty. Additionally, the results indicated that only two of the five total service qualities, ease of use and the security/privacy qualities, have positive influences on customer satisfaction. Customer satisfaction has also proven to be a significant influence on loyalty. Lastly, the results showed that among the factors of switching barriers, the factors of lost performance costs, sunk costs, setup costs, the attractiveness of alternatives, and service recovery have moderating effects on the relationships between customer satisfaction and loyalty. Base on the results, this research recommends that firms aim at devising integrated strategies that make switching barriers act as complements to customer satisfaction.

This study aimed to examine the influence of emotional information on task switching performance from a cross-cultural perspective. Specifically we investigated whether the impact of affective information differs between Koreans and Caucasian when they perform a switching task using pictures that express positive and negative emotions. In this study, Korean and Caucasian college students were presented with either positive or negative faces and asked to perform either an emotion or a gender judgment task based on the color of the picture frame. The results showed that the switching cost from the gender judgment task to the emotion task was significantly larger than the switching cost from the gender task to the emotion task for both Koreans and Caucasians. This asymmetric switching cost was maintained when the previous and current pictures showed the same emotion but disappeared when two images presented different emotions. Regardless of the participant's cultural background, switching costs were greater for emotional tasks where the emotion was directly related to the task than for gender tasks. However, the effect of emotional switching on switching costs varied by the individual's background. Koreans were less sensitive to whether poser's emotion was changed than Americans. These results demonstrate that emotional information affects cognitive task performance and suggest that the effects of emotion may differ depending on the individual's cultural background.

Long-term customer retention strategies with switching cost is very important for gaining a competitive advantage in on-line shopping mall environment. The purpose of this study is to investigate the affecting factors of switching cost in terms of on-line shopping mall's quality and the effects of it on customers' behavior moderating commitment. According to the result, information quality and customized information were found to be significantly related to social switching cost, and also royalty program and product differentiation were found to be significantly related to lost benefit cost and procedural cost respectively. When it comes to the relationship between switching cost and commitment, results shows that social switching cost is not significantly related to affective commitment. Lost benefit cost and procedural cost, however, were found to be significantly related to affective commitment and calculative commitment respectively. Finally, affective commitment was found to bolster repurchase intention and control negative WOM, and calculative commitment was found to bolster both repurchase intention and negative WOM.

Owing to handset subsidies, large growth in the Korean mobile telephony subscribers has occurred. While most of firms create artificial switching costs by rewarding customers for repeated purchases to retain their customers, mobile telephone carriers discriminate against loyal customers through handset subsidies. This article examines the effect of switching cost on the prices and profits in a two-period, differentiated product duopoly model.

Using the general switch management protocol on a multi-protocol label switching network, we present an efficient method for handling handovers. The proposed method directly changes an established path into a new path for supporting a handover. Our investigation reveals the effects of the proposed scheme and demonstrates that this method significantly reduces signaling costs and delays.
