Purpose: Due to the explosive growth and widespread use of smartphones, new business opportunities are emerging. Despite the importance of creating customer value in using smartphone applications, past studies on have mainly focused on functions or factors and specifications that influence users to use the device. Methods: This study is intended to identify how customer dissatisfaction from the use of smartphone application services affects customer sentiment and behavior. The research model is tested via a survey of 290 smartphone application users. Results: The result of this empirical study indicates that customer dissatisfaction significantly affects the user's disappointment and regret in using a service, which are subordinate values of customer emotion. The user's anger is positively associated with 'Negative word of mouth' and 'Complaint', which are subordinate values of customer behavior, but not with an intention to switch to another service. 'Regret' and 'Disappointment' are positively associated with 'Negative word of mouth' and 'Switching intention', but not with 'Making direct complaints'. Finally, customer's negative sentiments are a significant intermediary in the relationship between customer dissatisfaction and behavioral response. Conclusion: Finally, the study offers a more systematic understanding on the phasal response process of customer dissatisfaction in relation to the provision of smartphone application services.

Purpose: There have been terrorist attacks all over the world, causing massive damage. In Korea, there are few cases of terrorist damage, but the lack of the on-site response experience lead to constraints on the opportunity to verify capabilities against terrorism. Therefore, in this study, the chemical terrorism on-site countermeasures is considered as a concept of service, it was possible to draw up improvement alternatives for each element by reviewing at once the interactions between the concerned organizations and citizens in the field and the utilization of the equipment and facilities in the invisible area. Results: It had been evaluated the service process of the counterpart manager from the viewpoint of the victim citizen, who is the beneficiary of the final security service. It has found out the waiting point(W.P) between the victim's civilian incident management, and the element of failure(F.P). Conclusion: In this way, comparing chemical terror incident response manuals belonged to each related organization by fusion of service design approach and scenario technique, It is expected that it will be able to find out more specific problems and to find improvement alternatives.

Purpose: 'The purpose of the present study was to understand students' experiences from their standpoint, to identify relevant variables and to examine into their relations by analyzing and describing what phenomenon 'nursing students' visiting ambulatory bathing service' is, what are the reasons for the phenomenon, and what interactions are in the phenomenon. Method: The subjects were thirteen students. Data were collected through in-depth interviews and analyzed by Strauss and Corbin's analysis method. Result: With regard to ambulatory bathing service, participants responded 'lack of education', 'inexperienced personal relations' and 'disappointment with recipients families'. They recognized 'burden' and 'compassion'. The intensity of generated 'burden' and 'compassion' was determined by volunteering persons, the degree of health care service, recipients' response and interaction of climate. When 'burden' and 'compassion' were generated, participants selected their own coping strategies. Strategies in the situation of 'burden' and 'compassion' were significantly influenced by 'burden' and 'compassion' and structural situation - 'mutual relation structure,' 'volunteers' capability,' 'the degree of volunteering guidance,' 'community participation,' 'recipients' environment,' 'information sharing,' 'special vehicle equipment' and 'economical burden.' Strategies include' service training,' 'receiving volunteering training,' 'preliminary service preparation,' 'volunteering.' 'connection to local medical center,' 'intention,' 'information sharing,' 'passive response to recipients' appreciation' and 'the understanding of publicity'. The results of selected 'burden' and 'compassion' are described with 'worthiness' and 'cohesion' as follows. Conclusion: This study is significantly meaningful in that it examined bathing service welfare in its initial stage. There are not much outcome from previous studies. However. it is meaningful that this study intended to develop theories on the nature of experiences and the relations among concepts derived from the visiting ambulatory bathing service process of nursing students. Professors who taught social volunteering in universities understood the experience of nursing students who did the visiting ambulatory bathing service. Consequently, professors will provide an effective instruction to enable these students to carry out visiting ambulatory bathing services efficiently in order to meet demands when they conduct the services. For the volunteering service activity in major-related fields among college students' social volunteering activities, they recognized the necessity of systematic education and preparation.

This paper discusses the types and importance of service trade. The service trade, which has become increasingly important, is shaped by the General Agreement on Trade in Services (GATS). However, the availability of trade data is still low. The service is expected to increase the value added of the manufacturing industry and to lead the trade enhancement effect beyond the current stagnant commodity trade. Such effects are also confirmed by studies using the OECD Service Trade Restriction Index. Korea's service trade is relatively low compared to commodities's, and some items are still in a chronic deficit. In order to overcome such a situation and develop the service industry, it may be considered to pursue active service opening around major industries. It is also possible to suggest a Korea Standard that mediates between developing and developed countries.

Sample attrition according to a long-term tracking reduces the representativeness of the sample data in a panel study. Most panel surveys in South Korea and other countries have prepared response adjustment weights in order to solve problems regarding representativeness due to sample attrition. In this paper, we divided the panel data into continuous response group and non-continuous response group according to response patterns and considered a weighting adjustment method to reduce the bias of the non-continuous response group. A simulation indicated that the proposed composite estimation type weighting method, which reflected the characteristics of non-continuous response groups, could be more efficient than other weighting methods in terms of reducing non-response bias. As a case study, the proposed methods are applied to the Korean Longitudinal Study of Ageing (KLoSA) data of the Korea Employment Information Service.

Commercialization of AIS, it make be possible to provide VTS service efficiency and to decide quickly navigational action among vessels. Communications at sea mostly doing by communicating equipments(SSB, VHF, etc.). Especially, it is impossible to provide VTS service to non-listening vessels and non-reponse vessels. These vessels are main reason that make the problems communcating among vessels at sea. Solution of these, Displaying stand by channel of each vessels in real time, it can be improve response rate(factor) to non-listening vessels and non-response vessels. It will bhe helpful to improve safety at sea.

Modal parameters including resonant frequencies and mode shapes are heavily utililized in most damage identification throries for structural health monitoring. However, extracting modal parameters from dynamic responses needs postprocessing which inevitably involves errors in curve-fitting resonants as well as transforming the domain of responses. In this paper, the applicability of a damage identification method based on free vibration responses to the in-sevice responses is experimentally verified. The experiment is performed via applying periodic and nonperiodic moving loads to a simply supported beam and displacement responses are measured. The moving load is simulated using steel balls and a downhill device. The damage identification results show that the in-service response may be applicable to identifying damage in the beam.

Context-aware service environment should provide many kinds of services according to users' requests. Users want a great variety of services. In response to their demands the service provider should make a new service every time. But making a new service every time may be inefficient even for a small number of users' requests. So, there are studies on how to efficiently support various and complex requests fFom users. In many researches, service compositions have lately attracted considerable attention. However, existing researches have mainly focused on Web services. So they are not proper to rapidly providing services in response to users' requests, especially In context-aware service environment. This paper proposes a rapid service composition using case-based reasoning. For evaluating the proposed algorithm we implement 'purchasing seTvice agent'. With this system, we compare our algorithm and the existing service composition algorithms.

The issues that we should consider in the process of providing mobile web service using a mobile device are seamless service and QoS-guaranteed service. HMIPv6 has MAP because of improving packet loss and transmission delay due to disconnection. However, a load is concentrated on HMIPv6 because of receiving and delivering packet for MN. Owing to this, real time data fails to be processed quickly, and also adaptive mobile service is required for QoS guaranteed service. However, this method demands the response time cost of contents service owing to the hardware differences of various devices. Therefore, we improve the process performance of real time data by applying a queue in MAP for seamless service in this paper. For decreasing response time cost, we propose mobile web service method which has reusable cache of contents using the elements of contents. The result of a numerical formula and simulation shows that our proposed method is superior under various system conditions.

This study attempts to find out what kind of service quality is considered important by customers in using the Internet shopping mall and suggests the way to activate the customer relationship. The findings based on empirical analysis are shown here. First, empirical analysis of the contextual factors such as gender, education, and experience levels, shows that what customers perceive as most important in the product purchase is security in terms of the payment and personal information service. The second important service quality factor perceived by customers is responsiveness, particularly the rapidity and accuracy of response to their needs and wants. The customers also considered price, quality and diversity of the product as being important. Furthermore, there is no big difference among other service quality factors. Second, in the different gender context, there is no significant difference between the genders. However, the male group shows an even distribution of factors valued in the service quality, whereas female respondents placed stronger emphases on particular aspects of service, such as security, response, reliability and product quality. Third, in the context of different education level, the payment method between graduates and non-graduates has a significant difference. That is, the non-graduates prefer the credit card and saving through ATM, while the graduates use dual payment method using credit card and another payment method together. Therefore, the various payment methods should be considered according to the customer type, namely graduates or non-graduates. Fourth, in the context of different experience level, the result of the empirical analysis of the factors of the service quality shows no great difference between experienced and inexperienced customers. Both types of customer perceive security as the most important. To sum up, the service quality perceived by the customers of Internet shopping malls is empirically analyzed in different contexts such as gender, education, and experience. Then, the device for the customer relationship activation is suggested. It can be utilized as a guideline for the continuing diffusion of the Internet shopping mall, giving it a competitive advantage against other companies.
