The quality of gifted education depends on the quality of teachers in the field. Teachers in music (Korean traditional music) gifted education are significant variable in identifying students' giftedness and successful instruction. The purpose of this study was to explore the desirable components of teachers in music (Korean traditional music) gifted education and develop the evaluation criteria based on the desirable components. Previous research on the components of good teachers, teachers in gifted education and teachers in music (Korean traditional music) gifted education were reviewed. Based on literature review, the evaluation criteria of teachers in music (Korean traditional music) gifted education was developed. To collect opinions and derive consensus of the evaluation criteria, this research used Delphi method with a panels of 25 experts. The evaluation criteria classified with 3 dimensions, 8 categories, and 18 variables as the result.

A concept of sustainable development has become a major concern in international debate on water resources development and environmental conservation. Although sustainable water resources development and management takes a significant amount of concern in the development research, its applicability has not been insufficient in practices. The purpose of this study is to address a definition of sustainable water resources development and management and to illustrate relevant indicators. The study has also attempted to develop localized indicators hence to assess an availability of water resources development and management and to evaluate the water resources in Korea with the indicators which have been developed in other countries.

The purpose of this study was to develop evaluation indices for forest landscape classification. The indices were chosen to enable forest managers to establish effective landscape management strategies through three times of focus group interviews and email survey with experts. The 13 landscape evaluation indices were finally divided into four categories. They were ecological health (degree of green naturality, degree of ecological naturality, disease and insect damage, crown vitality), aesthetic visual quality (naturalness, harmony, diversity, traditionality, aesthetic appreciation, rarity), and sensitivity (level of tourism/recreational use), interruptions (damaged land, artificial structures). The five-level was suggested for the forest landscape classification system.

This paper investigates the applicability of a modified version of TOPMODEL considering shallow subsurface storm flow in a forested mountaneous catchment. The macroporous soil structure provides a hydrological pathway for rapid runoff generation. A modified version of TOPMODEL introduces the two-storage system to analyze the hydrograph recession including rapid subsurface storm flow component. The two-month continuous hydrologic simulations of sulmachun watershed suggest that a modified version of TOPMODEL represents comprehensive and realistic flow generation mechanism comparing to those of an original version of TOPMODEL. The results of parameter calibration with Monte-Carlo method indicate a modified version of TOPMODEL produces a set of physically meaningful parameters.

The purpose of this study is to analyze the association between indicators and to find statistical models based on important indicators at 'College Notifier' in Korea Council for University Education. First, Pearson correlation coefficients are used to find statistically significant correlations. By variable selection method, the important indicators are selected and their coefficients are estimated. As variable selection method, backward and stepwise methods are employed.

In this study we investigate the importance of the subway station using network centrality measures. For centrality measures, we have used betweenness centrality, closeness centrality, and degree centrality. A new measure called weighted betweenness centrality is proposed, that combines both traditional betweenness centrality and passenger flow between stations. Through correlation analysis and power-law analysis of passenger flow on the Seoul metropolitan subway network, we have shown that weighted betweenness centrality is a meaningful and practical measure. We have also shown that passenger flow between any two stations follows a highly skewed power-law distribution.

전력선 통신 기술의 발달에 따라 다양한 전력선 통신 핵심 기술들이 적용된 모뎀이 개발되고 있는 시점에서, 상용화에 앞서 모뎀 성능에 대한 실제적인 측정과 검토가 요구된다. 본 논문에서는 저압 전력선(옥내) 통신 테스트 베드를 구성, 이를 통해 모뎀의 네트워크 성능 지표들에 대한 실제적인 측정을 수행하였다. 저압 전력선은 220V저압에 옥내 배전선 약 16m로 구성되었으며, 측정된 네트워크 성능 지표는 RFC2544, RFC2285에서 권고하는 네트워크 성능 지표들 중, 일대일 처리율, 일대다 처리율, 다대일 처리율, 일대일 지연시간, 일대일 프레임 손실이다. 측정에 사용된 전력선 모뎀의 성능과 지표들의 측정값을 통해 모뎀의 성능과 속도뿐만 아니라 전력선 통신 어플리케이션 적용 여부 등 전력선 통신 시스템 개발과 상용화에 실제적인 검토가 가능하다.

The purpose of this study was to analyze the performance evaluation index for a salt reduction project. Questionnaires were developed in order to investigate salt reduction programs nationwide. The evaluation index and programs were analyzed through the case study of a salt reduction program in public health centers. The validity of the salt reduction program's evaluation index was determined based on study of the Delphi survey and on discussion with nutrition and health care professionals. The Delphi survey showed that daily salt intake was the most valid nutritional evaluation index. Stroke mortality and stomach cancer mortality were good health care evaluation indexes. The method for measuring salt intake that had the greatest validity was a 24-hour urine collection. However, 24-hour urine collection had the lowest score for ease of performance. The combined scores of validity and ease of performance showed that the survey method for dietary attitude and dietary behavior, dietary frequency analysis (DFQ 15), and a salty taste assessment, in that order, were proper methods. The high reliability of the salty taste assessment indicated that the percentage of the population that exhibits proper salt intake (2,000 mg sodium or less daily) and the percentage of the population that consumes low-salt diets as nutritional evaluation indexes also will be helpful to evaluate performance of salt reduction programs.
