New buildings are to be needed for an aging society. But, there may be a solution on the multi-purpose & mixed-use existing facilities. Therefore this study is focused on verification of mixed-use school facilities's potentialities. If possible, I want to suggest some directions of renewal primary school planning. The results of this study are as follows : 1) It is important to make a policy for improving the educational environment, 2) Future buildings must be planned by the principles based on the lifelong learning, 3) Mixed-use building blocks need to be laid out by the concept of accessibility, 4) We can use existing primary school's areas as a elderly welfare facilities without any renovation and increasing areas.

This study aimed at proposing policy improving directions of the rural empty homes grant scheme in Korea. The implementation procedures and results of the relevant schemes/projects on optimum use of rural empty homes at home and abroad were reviewed by literature and internet searches. From the reviewing results, a tentative set of policy directions for project improvement were proposed: extention of project scope to all the redundant resources, dual focussing of project objectives on housing innovation and economic regeneration of communities, and systematization of project plan and implementation especially in the statutory aspects.

As the demand for high-performance semiconductors, such as chips for artificial intelligence and high-bandwidth memory devices, increases along with the limitations of ultrafine processing technology in the semiconductor in-line process, advanced packaging becomes an increasingly important breakthrough technology for further improving semiconductor performance. Major countries, including Korea, the United States, Taiwan, and China, and large companies are strengthening their technological industry capabilities through the development of advanced packaging technology and policy support. Nevertheless, Korea has a lower level of development of related technologies by approximately 66% compared with the most advanced countries. Therefore, we aim to discover the needs for an advanced packaging research and development (R&D) policy through written expert interviews and importance satisfaction analysis. As a result, various implications for R&D policy directions are suggested to strengthen the technological capabilities and R&D ecosystem of the Korean advanced packaging technology.

We have presented the tracing algorithm for center pixel of character image. Character image was read by scanner device. Performing the tracing process, it can be possible to detect feature points, such as branch point, stroke of 4 directions. So, the tracing process covers the thinning and feature point detection process for improving the processing time. Usage of suggested tracing algorithm instead of thinning that is the preprocessing of character recognition increases speed up to 5 times. The preprocessing chip has been designed by using single layer perceptron algorithm.

In this paper, we propose a non-edge following method for linear programs. Unlike alledged poor performance of algorithms of this type, this method performs well at least with 25 randomly generated problems. This method is comparable to Rosen's gradient projection method as applied to the dual formulation. The latter is of general purpose, and no implementation rules are available for linear program applications. This paper suggests ways of finding improving dual feasible directions, and of allowing to move across the extreme faces of a higher dimension polyhedron. Rather simple computational rules are provided for projection operations needed at each iteration.

The edge detection system makes use or 3*3 compass gradient masks, which are well suited for digital implementation. Edge angles are quantized to eight equally spaced directions, suitable for chain coding of contours. Use of edge direction msp improves the simple thresholding of gradient modulus image. The concept of local connectivity of the edge direction map is useful improving the performance of this method as well as other edge operators such as Kirsch and Sobel.

Adjuvant therapy for completely resected esophageal squamous cell carcinoma is less commonly applied in clinical practice than neoadjuvant therapy, but it plays a substantial role in improving survival for esophageal cancer patients. This article presents a concise review of the evidence regarding adjuvant therapy for esophageal squamous cell carcinoma and future directions, particularly immunotherapy.

This study aims to suggest the directions of the elementary school landscaping in terms of environmental education. The 96-case of school landscaping projects had been implemented for 2001 - 2002 in Seoul was selected, and the trends and contents of the projects for improving the school landscape was reviewed. Also, specially the 9-case among them was selected and analyzed whether or not the projects were effective for the environmental educational places. The paper showed that it was not fully matched with the environmental education programs in the textbooks that need the actual spaces and facilities including woods, outdoor class, kitchen garden, breeding farm and ecology pond etc. Also, it appeared that the teachers and students did not satisfied with the projects for improving the school landscape. Finally, this paper suggested that the species diversity of plants and animal, water and forest environment should be emphasized on the school landscaping.

The enhancement of the quality of the teaching practice is a major factor in securing better schooling opportunities for students. In this article, initial teacher preparation of secondary school Earth science teachers, in-service science teacher education, and improving teacher policy are discussed. Data from in-depth interviews with exemplary science teachers were used to explore how to improve the quality of science teacher education in Korea. In terms of preservice teacher education, most exemplary teachers contended that teacher education programs should provide preservice teachers with practical knowledge by translating theory into practice. Their suggestions for how to improve in-service education are also discussed. Regarding directions of improving teacher policy in Korea, the teachers proposed an alternative teacher-promotion structure that incorporates the master-teacher position. Implications for introducing action research courses into teacher (re)education programs are also discussed.

Agricultural R&D Programs of the Ministry of Agriculture and Forest and the Rural Development Administration are important for improving agricultural technology in Korea. However, the roles of these two agencies have been overlapped as the research fields and funds are extended through educational-industrial-governmental-institutional cooperation programs. In this study, we analyzed the performances of two agencies. As a result, these programs of these agencies do not show much difference in the research area. A new direction for improving efficiency and solving problems of programs, with a variety of information about the role of two agencies and activation of agricultural R&D programs, will be provided by this performance analyses.
