The task evaluating science and technology is becoming more important in every country trying to develop and improve overall national R&D capability in an effort to sustain national prosperity and public welfare. However, the way in which evaluation organisation is approached in each country may differ from nation to nation reflecting national R&D systems and S&T policies as well as the specific roles of scientists and policy- makers at various levels. Over the past two decades or so, Korean evaluation system has been transplanted form the West and they modified, In addition, Korea borrowed elements from the Japanese. Whether such systems have been well rooted in our specific circumstances is a critical question. In this context, it would be meaningful to diagnoses the current Korean evaluation system and also makes some suggestions for improving this system. For this purpose, this paper also attempts to approach to the theoretical aspects of evaluation as a starting-point.

The CORBA that supports FPGA has not been used generally and it is difficult to implement and to develop the CORBA for FPGA. In this paper we propose the way to design FPGA to support a CORBA component. For FPGA to support the CORBA component, embedded processor provided by FPGA and PCI based CORBA is utilized. The PCI based CORBA is for improving data transfer throughput. This paper will be organized as follows. In Chapter I, existing research trend and background are presented for why we propose design of FPGA that support the CORBA component. In Chapter II, FPGA design for supporting CORBA components is proposed and described in detail. In Chapter III, simple experiment is tested to confirm the proposed FPGA design. Finally session 4 is conclusion of this paper.

The purpose of the present study is to explore the process of teacher change as elementary school teachers participated in a community focused on improving mathematics teaching. To do so, a professional community lot improving instructional practice consisted of a group of voluntary elementary school teachers. The professional community provides participating teachers with great opportunities to share their understanding of practical knowledge related to mathematics teaching and learning and change mathematical beliefs as well as to learn pedagogical content knowledge. This study approached to teacher professionality in terms of mathematical beliefs and teaching practice. The change of teaching practice was measured coherently both with a questionnaire and with a mathematics teaching standard developed for this study. The findings of this study point out that techers' beliefs about how students learn mathematics have chantged. This study also indicated that after participating in the professional community focused on improving mathematics teaching, teachers' mathematical teaching is changed toward the more students' oriented way. Especially, it is observed that the meaningful change in participating teachers' teaching practice took place with respect to the role of teachers, students' interaction, mathematical tasks, and problem solving. Finally, this study implies that teachers can have an opportunity to change their beliefs and deepen their professionality about elementary mathematics teaching and learning through participating in the community of practice, through which participating teachers can share their practical knowledge and their understandings about teaching and learning of elementary mathematics.

The study was carried out to determine the real condition in parking environment improving zone suffering poor supply for demand and then present a solution to it. To this end, the study reviewed the existing data including parking ratio which means percent of the total parking space in the region divided by the number of registered vehicles in the zones and surveyed residents for their awareness of parking lots. The results showed some major findings as follows. Parking ratio is low and illegal parking is serious in the zones, which, as a consequence, it results in lack of parking area in the zones. More than 70% of those who live in the zones had inconvenience during parking. And insufficient space for parking generates illegal parking. Residents in the zones answered that the best way to deal with the parking problems is to create more parking zones. As they had more difficulties having parking spaces, they showed stronger tendency to use newly-built parking lots. The study also gave thought to building private parking lots as a solution to the parking issues in the zones. And it suggested that supporting policies on the private parking lots be strengthened to promote the private parking lots in residential areas. Those policies will gradually improve parking problems in the parking environment improving zone.

Current increasingly information systems log historic information in a systematic way. Not only workflow management systems, but also ERP, CRM, SCM, and B2B systems often provide a so-called 'event log'. Unfortunately, the information in these event logs is rarely used to analyze the underlying processes. Process mining aims at improving this problem by providing techniques and tools for discovering process, control, data, organizational, and social structures from event logs. This paper focuses on the mining social networks. This is possible because event logs typically record information about the users executing the activities recorded in the log. To do this we combine concepts from workflow management and social network analysis. This paper introduces the approach and presents a tool to mine social networks from event logs.

AdaBoost tweaks the sample weight for each training set used in the iterative process, however, it is demonstrated that it provides more correlated errors as the boosting iteration proceeds if models' accuracy is high enough. Therefore, in this study, we propose a novel way to improve the performance of the existing AdaBoost algorithm by employing heterogeneous models and a stochastic twist. By employing the heterogeneous ensemble, it ensures different models that have a different initial assumption about the data are used to improve on diversity. Also, by using a stochastic algorithm with a decaying convergence rate, the model is designed to balance out the trade-off between model prediction performance and model convergence. The result showed that the stochastic algorithm with decaying convergence rate's did have a improving effect and outperformed other existing boosting techniques.

Purpose: This study was survey on future job vision and its pride (self-esteem) of dental technicians. It also investigates the future vision on their major of job (denture) and its awareness to improve the work environment and enhance their satisfaction towards job and duties. Methods: In order to research job and its duty satisfaction of dental technicians who mainly work at denture part, certified questionnaire was modified and upgraded for its use. Collected documents were used by 'Window SAS 8.0 Program' for analysis. The significance of the test related to the items and its standards has been decided for p<0.05. To find out the differences between choices when choosing career and the duty satisfaction, t-test, one-way ANOVA and two-way ANOVA have been used. Results: Following research findings show: 1. There was high self-esteem towards the job as dental technicians but low in future job vision. 2. It has been found that if satisfaction on their job (dental technician) is high then also their satisfaction on its duty (denture part) is high. 3. The factors that affects mostly on duty satisfaction of denture part are 'the contribution on improving oral cavity of people'(${\beta}$=0.33118), 'The possibility of growth of person's job choices'(${\beta}$=0.30035) and 'person's satisfaction on choosing job'(${\beta}$=0.16069). 4. If there is an increase level on the contribution of improving people's oral cavity, the possibility of growth of person's job choices and the person's satisfaction on choosing job, then there is also high growth in denture part's duty satisfaction. 5. It has been found that if there are more employment histories of denture part, the duty satisfaction of denture part were also high. On the other hand, the more employment history of dental technicians get, the duty satisfaction of their denture part was low. Conclusion: Following research results show that there is high self-esteem towards the job as dental technicians but the vision towards future was low. This shows that there is no bright future on dental technology. Therefore, it is important that not only to improve the work environment and pay rise on dental technologists but also to satisfy them. Various program developments and continuous research are needed to increase satisfaction.

Korea has made a rapid economic development since the last three decades. This has helped Korea narrow the gap in health service differences in resource availability and in quality of care. However urban and rural differentials are still remarkable. This study has maintained that health status of rural residents is inferior to that of urban dwellers. Therefore, this study was carried out to develop policy measures for improving health services in rural areas. In order to achieve the objective of this study the authors collaborated closely and made field visits, interviews and conducted an extensive literature review regarding rural health services. The following policy options are recommended as a summary ; First, the quality of rural health personnel is a single most important factor influencing the level of rural health services. An innovative program for public health doctors to the internship and/or residency training program such as specialty board program of family medicine. Second, dissatisfaction regarding employment of public health doctors is problematic. More rational employment and deployment programs are needed to meet their personal desire. One way to do this is to make it wide open and competitive. Third this study shows how to increase physician productivity in the rural public health sector. Incentive system needs to be elaborated for the career development of rural health workers. University linked job opportunity as clinical professor is an example. Fourth, without straightening the function of health centers and subcenters, the future of rural health services is doomed to failure. Straightening primary health care is one way to enrich the program of public health facilities and reactivating the operation of health center/hospital is another. A close linkage of public facilities with private hospitals is a minimum requirement for the operation of health delivery system within a health district. Fifth, some measures are urgently required to enhance hospital services in medically underserved areas. Financial subsidy, tax exemption, long-term public loans and higher priority of health manpower deployment are some of them. Sixth, new health programs should be in tiated to meet changing needs of peoples in rural areas. Home health care program, hospice program, nursing home, residential program for the elderly are recommended.

This study describes the impact of early childhood teacher's artistic competence on art education pedagogy and improved curriculum design. Furthermore, the effect of drama as a way of improving early childhood teacher's artistic competence is explained. Many researchers have mentioned that early childhood is a period of sensitivity and potential. Therefore, it will be helpful if children meet a teacher who understands them and inspires their innate artistic sense at a level of their eyes. It explained which aspect of artistic competence should be focused for the teacher training education. There are many approaches to develop early childhood teachers' artistic competence. Adopting drama is one of them. The strong points of drama to improve their artistic competence are as follows. Firstly, human's movement and voice are the main artistic channel in drama. What we are doing in daily life is found are drama world. It means if early childhood teachers experience drama activity, they will feel more comfortable and intimate with it. In addition, early childhood teachers tend to be familiar with dramatic play, so they can more easily access to drama world. Secondly, drama will be helpful to understand different feelings and to broaden and deepen understandings of others' standpoints. For early childhood teachers, drama activity will be helpful to understand how dramatic art form works and to lead children's play in diversified and sincere way. In addition, drama activity will be useful to build horizontal and democratic relationships between children and the teacher. It is one of the main emphases of 2019 revised Nori national curriculum. To sum up, drama will be a excellent method to develop artistic competence for early childhood teachers. Thus, it is expected that They have more opportunities to experience drama as an art form.

The purpose of this study was to identify latent profiles of multicultural adolescents' psychological outcomes (school participation, self-esteem, and difficulty related to multicultural identity) depending on their perception of the parent-child relationship. A total of 5,540 samples from the Multicultural Adolescents Panel Study (MAPS) conducted by the National Youth Policy Institute in 2018 were analyzed by using Latent Profile Analysis and one-way ANOVA. The best-fitting model identified five groups according to their perception of the parent-child relationship: (1) father low-mother average (6.5%), (2) father average-mother low (2%), (3) father low-mother low (18.6%), (4) father average-mother average (31.2%), and (5) father high-mother high (41.7%). According to the results of one-way ANOVA, the father high-mother high (41.7%) group of adolescents showed more school participants and higher self-esteem and multicultural identity than the other profiled groups. The father average-mother average (31.2%) group of adolescents also scored higher than the other three groups (father low-mother average (6.5%), father average-mother low (2%), and father low-mother low (18.6%) of adolescents). The results of this study imply that improving multicultural adolescents' perception of their parent-child relationships would be important in improving psychological outcomes.
