As the management and preservation of the environment become an important social issue, information required to support environmental task is required. So, there is an increasing demand for environmental information and appropriate systems to manage it. The vast volume of environmental data is distributed in different knowledge domains and systems. Environmental data objects have the complex structure containing environmental quality data and attribute data. Environmental information systems must be able to address these properties. This research has aimed at constructing well-defined schema design of environmental data, and making system architecture that environmental data kept by authorities should be made available to the public user. There are 3 major components in environmental information systems architecture ; User interface, Catalog libraries, Communication Provider. Web browsers provide consistent and intuitive user interfaces on Internet. The communication provider is a collection of diverse CGI functions. The main roles of the CGIs are to build interfaces between the Web, databases. Catalog libraries is libraries of various matadata including administration matadata. Administration matadata support the environmental administration and the managerial aspects of environmental data rather than explain a database itself or its properties.

Multimedia applications over wireless networks have been evolving to augmented reality or virtual reality services. However, a rich data size compared to conventional multimedia services causes bandwidth bottlenecks over wireless networks, which is one of the main reasons why those applications are not used widely. To overcome this limitation, bandwidth aggregation techniques, which exploit a multi-path transmission, have been considered to maximize link utilization. Currently, most of the conventional researches have been focusing on the user end problems to improve the quality of service (QoS) through optimal load distribution. In this paper, we address the joint pricing and load distribution problem for multi-homing in heterogeneous wireless access networks (ANs), considering the interests of both the users and the service providers. Specifically, we consider profit from resource allocation and cost of power consumption expenditure for operation as an utility of each service provider. Here, users decide how much to request the resource and how to split the resource over heterogeneous wireless ANs to minimize their cost while supporting the required QoS. Then, service providers compete with each other by setting the price to maximize their utilities over user reactions. We study the behaviors of users and service providers by analyzing their hierarchical decision-making process as a multileader-, multifollower Stackelberg game. We show that both the user and service provider strategies are closed form solutions. Finally, we discuss how the proposed scheme is well converged to equilibrium points.

Service failures are fairly common these days, and recovering from them is difficult. If service failures are not addressed quickly, the service provider may lose revenue and customers. A good service recovery strategy will positively impact the business results of the service provider. The study aims to demonstrate the impact of service recovery on the satisfaction and word of mouth of international visitors towards homestays in the Mekong Delta, Vietnam. The research data was collected from 320 international visitors who have used services at homestays and experienced service failures in the Mekong Delta, Vietnam. Structural equation modeling was applied to analyze the data. The result shows that 3 dimensions constitute service recovery which are distributive justice, interactional justice, and procedural justice. Most importantly, the study has proved the positive impact of service recovery on both satisfaction and word of mouth of overseas tourists towards homestays in the Mekong Delta, Vietnam. The results have stressed the importance of service recovery to tourists' perceptions of service quality and service image. In addition to this, the study suggests that homestay owners should develop risk handling and risk prevention plans for their services.

This study explored the relationships between unmarried adult children and their coresident parents with a focus on the role of intergenerational exchanges and family values affecting parent-child relations. A total of 767 unmarried adult children who lived with their parents were selected from the data of the third National Korean Family Survey in 2015. The main findings were that coresident adult children exchange diverse resources with their parents and that exchange patterns whether receiving more or giving more differed depending on the helping dimensions. 'Receiving' type was more prominent in the dimension of practical help, while, 'receiving and giving' type was more noticeable in the dimension of emotional help. Findings also suggest that intergenerational exchange and family values contribute to parent-child relationship quality. While being an active provider of practical help is positively associated with relationship quality, being a recipient of emotional help is related to a higher level of relationship quality compared to being indifferent. In addition, a stronger value of family responsibility was associated with a higher level of relationship quality. These findings indicate that the importance of the practical and emotional component in the relationships between unmarried adult children and their co-resident parents and reciprocal intergenerational exchange and strong family values may be contributory factors to better parent-child relationships.

The rapid change in almost every area of science at the turn of the 21st century have also affected libraries and information centers. Whatever the change, from the library users' perspective, the functions provided by the library, is perceived as "service" and the satisfaction of the users can only be measured by the quality of the service. The library and information center acting as a service provider aims to establish a framework for improvements in services by focusing on the user's perspective on service quality and classifying the factors that contribute to service quality. This study adopted the LibQUAL+ model, which is derived from SERVQUAL model for measuring quality of service in the field of Service Marketing.

The relationship quality and recovery of service failures perceived by consumers play an essential role in affecting the service provider's image and sales in terms of the highly involved service industry. In particular, implementation of successful relationship marketing strategies and effective recovery of service failures provide greater satisfaction for customers expecting customized services and reinforce the relationships between the companies and consumers. Based on these previous studies, this research conducted to find out the causal relationship between the variables influencing service recovery expectations and word of mouth(WOM) by approaching the severity of service failures from the perspective of relationship marketing and attribution theory. For the empirical analysis of this research, we conducted a questionnaire surveys of 360 service users of beauty salons, who have experienced in high-involvement services, and utilized 333 questionnaires for the final analysis. The hypothesis was experimented using the Structural Equation Model(SEM), and the results are as follows. First, we identified that the higher the customer perceived the severity of the service failure, the lower the quality of the relationship. Second, we verified that service users observed service failure as a temporary and uncontrollable factor as they distinguished service quality as higher. Third, the hypothesis that customers recognize service failures as a temporary one has a positive impact on service recovery expectation level is determined through empirical analysis. Forth, it was figured out that the higher the perceived quality of the relationship with the service provider, the higher the service recovery level expected by the consumers. At the same time, the hypothesis that optimism for service recovery expectation affects positive word of mouth has been verified. The results of this study help develop the customer-oriented business model of the service companies. Furthermore, the academic significance in that it suggested a new direction for the research of high-involvement service marketing.
