The purpose of this study is to prioritize the importance of urban railway service quality through statistical analysis. This was done to maximize customer satisfaction by providing customers of urban railway services (including LRT), operated by the local government, with a better customized service quality. It was hoped that this project would boost the need for public transportation by increasing customer satisfaction, which would eventually lead to more profitable revenue. The results of validity certification of expectations and perceptions before and after the use of government funded urban railway and private sector invested urban railways show that there are gaps for 18 items for the government funded urban rail projects (p<.01), while there is no significant difference for 2 items between expectation and perception (p>.05); private sector invested urban railway projects show differences for all 20 items (p<.001). Therefore, IPA analysis is conducted to improve the service quality; this should lead to a remedy that focuses on service quality. The findings of this study will contribute to providing management strategies for boosting customer satisfaction and creating revenue through customized service quality in the urban railway operating industry (including LRT), which is currently suffering from chronic deficits.

The purpose of this study is to develop the self-diagnosis methodology based on process for improving the effectiveness in public institutions service and to suggest it. For this goal, we would like to select the management methodology which can be easily handled from the viewpoint of working personnel in the public institutions and make it as a process. First, the strategy for the public institutions and the strategic task for practicing it are acquired using BSC (Balanced Score Card) which is now under the active research. At this time, the relative degree of significance is derived using the AHP (Analytic Hierarchy Process) which is conducted for the professionals and management to get the degree of importance in the strategic tasks. The acquired relative degree of significance and the figures related to the performance of each strategic task derived from the subsequent questionnaire are used to get the final highly efficient strategic task through IPA (Importance Performance Analysis). In this study, this process based self diagnosis methodology will be explained in detail using the case of Project A in order to verify the effectiveness of the management science technique on the self diagnosis of the public institutions.

In the aspects of existing cultivation and management of forest resources, national forest informatization has been promoted so that the public can use the resources and so that efficient and systematic cultivation and management of forest resources can be performed constantly. In particular, even though forest informatization has been attempted a lot despite the distinct characteristics of forest, the attempts have achieved little effects. Typically, many of the internal work systems of Korea Forest Service have been built for the purpose of collecting top-down data in the main office rather than the actual work site, and also, from the aspects of use by the public as well, various contents have been provided by the persons concerned, so useful information has not been able to be transmitted systematically. Therefore, Korea Forest Service has promoted IT governance concept and EA-based informatization as a way to solve enterprise problems and also reinforce work and service in the existing system to promote the project to build the foundation of national forest informatization. Based on this, this study suggests chief challenges or implications.

In this study, in order to strengthen the AI utilization competency of pre-service secondary science teachers, a project activity in which pre-service teachers directly create an 'AI-based molecular structure customized learning support tool' by using Google's teachable machine was developed and applied. To this end, the program developed for 26 third-grade pre-service teachers enrolled in the Department of Chemistry Education at H University in Chungcheongbuk-do was applied for 14 sessions during extracurricular activities. Then, the perceptions of 'understanding how AI works', 'efficacy of using AI in science classes', and 'plans to utilize AI in science classes' were investigated. As a result of the study, it was found that the program developed in this study was effective in helping pre-service teachers understand the operating principle of AI technology for machine learning at a basic level and learning how to use it. In addition, the program developed in this study was found to be effective in increasing the efficacy of pre-service teachers for the use of AI in science classes. And it was also found that pre-service teachers recognized the aspect of using AI technology as a new teaching·learning strategy and tool that can help students understand science concepts. Accordingly, it was found that the program developed in this study had a positive impact on pre-service teachers' AI utilization competency reinforcement and perception improvement at the basic level. Implications of this were discussed.

Traditional korean medicine which has long history and many clinical experiments stands out in bold relief because the medicine's point of view has been changed from medical treatment to disease protection and the wellbeing life through health care and complementary alternative medicine has been emerged for the incurable disease. Many traditional korean medical research has been conducted in the fields of preventive medical application, leading material drawing and medical service upgrade through eastern and western medical treatment and the more advanced project are being studied as time goes by. But because we have the hardship of manifesting traditional korean medicine's knowledge into detailed data and information in the field of analytical science and we don't have well arranged research trend data of it, researchers are using much time to survey the preceding research and planners needing more accurate research trend data to protect duplication and raise efficiency. So we have studied the traditional korean medicine's research trend to solve this problems by the method of bibliography applied for the preceding project results. Through the analysis of traditional korean medicine's 370 project reports we came to a conclusion that the R&D investment is concentrated on the university and research institute, the utilization projects are lower than basic and applied research, regional snobbism is excessive than the whole nation's R&D and advanced project has been started since 2006.

This research is intended to analyze the necessity of the integrated organization for the performance in order to the extension of scale and the systematic promotion concerning to the Korean medicine informational project, and to research the promotional method of Korean Medicine information through the constitution of organization for preparing the informational basic. There are three main important subjects to be done in this research project. The initial issue is to devise a comprehensive and systematic plan of Korean medicine information according to the Korean Medicine Rearing Raw('03. 8). Furthermore, it is necessary to reinforce the integrated informational ability of Organizations concerning to the Korean Medicine. Finally, with the above works accomplished, the overall standard of Korean Medicine Information should be settled. Initially, we compose an advisory committee of the Korean Medicine Information in the first year. The members of the committee include the informational coordinates of related government agencies, the experts in Korean Medicine Information, and specialists in the domains of computer science and information. In the next phase, we derive the promotional strategy for 'Center for Korean Medicine Information'. In other words, by means of analyzing the current issues and outstanding problems of on-going research projects and environments, the ultimate directions of the whole activities are established. Also, we build the medium and long-range road map of Korean Medicine Information Research by setting strategy for the policy projects related to the area. With the various research activities in this project, we can achieve the following practical strategic benefits. Firstly, we can lay a foundation for the Korean Medicine Information by establishing the fundamental plan for 'Korean Medicine Information Center'. Secondly, information strategic projects about 'Korean Medicine Information Center'. Secondly information strategic projects about 'Korean Medicine Information Development' can be performed in more systematic fashion and promoted by stages. Finally, by confirming the contents of the Korean Medicine of KMS system, we invent an opportunity of new project in the field of the Korean Medicine Information by means of practicing and managing the 'korean Medicine Information Custom Service'.

PURPOSES : Case studies of an asphalt-overlay project with a performance-based contract method were conducted on a national highway in Korea to evaluate the effect of the method on asphalt pavement maintenance. This study evaluated the procedure of the performance-based contract method. METHODS : In this study, an asphalt-pavement maintenance project for a national highway was assessed with a performance-based contract to investigate the advantage of the new contract procedures. This is the first trial applying the performance-based contract to a pavement-rehabilitation project in Korea. In the four case studies, the warranty period of the performance-based contract was designed for seven years. The research team monitored the construction site to compare the normal contract method with the performance-based contract method. The case studies' project sites were investigated after the end of the construction. RESULTS : Based on the limited case studies, the performance-based contract method could extend the service life of the asphalt pavement and reduce the pavement-maintenance budget because the quality control was well managed by the contractors. However, a few construction laws would be necessary to apply the performance-based contract method in the future. CONCLUSIONS : Using the performance-based contract, the construction company made great efforts to guarantee the warranty period and to apply the optimal maintenance method, based on the pavement distress condition. The contractor and the agency would need to understand the new performance-based contract system for it to be activated. Therefore, a proper education program for the performance-based contract system would be needed to educate the stakeholders regarding the procedures and their effects on the pavement management and maintenance.
