This study conducted empirical analyses to investigate the factors affecting the intention to use smart home services. Based on the previous relevant studies, the characteristics of smart home service were found to influence on the intention to use smart home service, and four variables(ubiquitous connectivity, reliability, context awareness, and security) concerning the service characteristics could be derived. And referring to the technology acceptance model(TAM), the updated TAM, IS success model, and the theory of reasoned action(TRA), three variables such as perceived ease of use, perceived usefulness and subjective norm were also likely to affect the intention to use smart home service, and the user innovativeness was inferred to play a role of moderating variable. In order to examine the research model and the hypotheses which could describe the relationship of the above mentioned variables, this study surveyed 447 people who were currently using or would use the smart home services, and then tested the hypotheses for 436 valid responses. The results of hypotheses testing showed that reliability, context awareness, and security have a significant effect on perceived usefulness and on perceived ease of use. However, it was found that ubiquitous connectivity significantly affected perceived usefulness but did not affect perceived ease of use. And perceived ease of use, perceived usefulness and subjective norm had significant effect on the intention to use smart home services. Also, user innovativeness as moderating variable was found to significantly influence on the magnitude of the relationship between ubiquitous connectivity and perceived usefulness and on that between reliability and perceived ease of use. This can be interpreted as the findings implying that innovative smart home-service users are likely to feel the smart home-services more useful than ordinary users when the degree of ubiquitous connectivity is higher, and are likely to perceive the use of smart home-services to be easier than ordinary ones when the degree of reliability is higher.

The opening of a second new airport is urgently needed to meet the growing number of visitors to Incheon International Airport. This study focused on effectiveness of mediating effects on the dedication to organization in order to determine why manpower resources of the airport service sector should take job-changing into account and to focus on staff who provide service to customers visiting Incheon International Airport management of airport service quality by providing a better service and preventing them from leaving their job. The results show that, first, only obligation conflicts and heavy workload affect the dedication to organization in terms of task-related causes. Second, compensation and relationships with seniors also affect the dedication to organization in terms of organization-related causes. Third, if more dedication is required, more employees will leave their job. Fourth, role conflict is the only reason to leave the job related to task. Fifth, only compensation and decision making affect the cause of the dedication to organization. The employer urgently needs to make a system to develop a relationship with colleagues and seniors, make a better work environment so that employees can work for a longer period and monetary or valuable compensation should be provided as indicated above in order to keep them employed.

This study is designed to find out the determinants of dual-earner wives' needs for family-supportive services. For this purpose, a hypothetical model which explains the relationships among 6 stressors, role overload, stress and needs for 4 family-supportive services is developed. Using the data collected by purposive sampling from 234 professional women and 208 blue-collar women living in Chinju and Sacheon, the hypothetical model developed in this study was tested. In order to examine occupational class differences, a model for professionals and another model for blue-collars were developed separately and compared. For data analysis, a covariance structure analysis was used. The best-fitting model for professional women (df=141, GFI=0.928, CFI=0.965) and the model for blue collar women (df=141, GFI=0.902, CFI=0.912) were found. As a result of comparing two models, 9 common relationships were found:l)Greater dissatisfaction with child care service increases role overload; 2)Longer work hours increases role overload; 3) Higher level of role overload increases stress; 4)Higher level of stress increase needs for leaves; 5)Older child increases needs for flexible work pattern; 6)Younger child increases needs for finalcial assistance for child care fee; 7)needs for financial assistance for child care increases needs for on-site child care services; 8)needs for on-site child care services increases needs for leaves; 9)needs for leaves increases needs for flexible work pattern. With the exception of these 9 common relationships, the analyses revealed substantial differences between professional and blue-collar dual-earner wives. Based on the common and differential needs between 2 groups of wives, the effective ways to provide family-supportive services according to the needs of individual dual-earner wives who are in different familial, financial, and work conditions were suggested.

As Big Data's value is perceived and Government 3.0 is announced, there is a growing interest in Big Data. However, it won't be easy for each public institute or local government to apply Big Data systematically and make a successful achievement despite lacking of specific alternative plan or strategy. So, this study tried to suggest strategies to use Big Data after arranging the area which local government utilize it in. As a result, utilization areas of local administration's Big Data are divided into four areas; recognizing and corresponding the abnormal phenomenon, predicting and corresponding the close future, corresponding analyzed situation and developing new policy(administration service), and citizen customized service. In addition, strategies about how to use Big Data are suggested; stepwise approach, user's requirements analysis, critical success factors based implementation, pilot project, result evaluation, performance based incentive, building common infrastructure.

In this paper, we studied on the building models of open educational resource service system for download or upload their own educational content to be shared with the others without worrying about copyright infringement. We first analyzed the building models of the international OER(Open Educational Resource) service sites. And then, based on these results, we present the new service models suitable to be built the open educational resource service system in phases. The proposed models have the flexibility to accommodate the needs of users and have the advantage that the copyright-related issues of the existing 'National Educational Information Sharing System' could be solved step by step.

As the Internet facilitates the rapid increase of information availability, the study on SDI service that provides users with relevant document in a timely manner has been developed. However, the practical use of this service has been low. This thesis aims at analyzing the reasons for this and developing relevance feedback based SDI system to improve the performance of the existing SDI system. Experimental systems that are developed for this study are SDI system based on users' minimum intervention feedback, SDI system based on perfect automation feedback, and SDI system based on users' maximum intervention feedback. The fourth system that utilizes the traditional SDI system is also studied to evaluate the level of performance improvement of the newly developed three types of SDI system. As a result of this study, SDI system based on users' maximum intervention feedback showed greatest performance improvement. The next performance improvement happened in order of SDI system based on perfect automation feedback, SDI system based on users' minimum intervention feedback, and the traditional SDI system. Feedback based systems showed greater performance improvement as they went through more feedback processes.

Archives should promote services to users using various outreach service methods. Although the archives' tour program is one of the effective means of services, there has been few studies on the archival tour program. This study investigated archival tour programs and tried to suggest a desirable tour program, with the Korean Presidential Archives as a case. For this study, four U.S. Presidential Libraries' tour programs were investigated and analyzed. Also, tour programs offered in similar organizations in Korea, such as Kim Daejung Library, Diplomatic Archives of the Ministry of Foreign Affairs, and National Library of Korea, were analyzed. Current tour programs offered by the Korean Presidential Archives were also analyzed and some limitations were identified. Based on the characteristics of the Korean Presidential Archives, which will be moved to independent building in Sejong City soon, desirable direction to organize tour programs for various user groups were suggested.
