  • The purpose of this study is to provide a basis for determining when a school established long term school plans accepted by analyzing the trend of increase or decrease elementary school students 30 years to target of following nine cities, 607 elementary schools in Korea - 4 metropolitan cities(Incheon, Seongnam, Su-won and Anyang), 2 central regional cities (Daejeon and Cheongju) and 3 southern regional cities(Busan, Yangsan and Kimhae) for this purpose. Results of this study are as follows: First, there were overwhelming numbers of type5 among15 types of increase / decrease in the number of students. Second, in comparison with the type of increase / decrease of the number of students by region, the metropolitan area is ranked as type5>type13>type10>type8, in the middle region type5>type11>type10>type13 and in southern region type5>type10>type11>type13>type2. Therefore, there were regional differences in the number of students. Third, the results of the Conflict Model I and Conflict Model II showed that Type1 and Type7 were not needed to be adopted.

  • The seasonal variation and frequency of precipitation phenomenon of the Korean Peninsula in summer show strong local weather phenomena because of its topographical and geographical factors in the northeastern area of Asia. The characteristics of the prevailing weather patterns in summer precipitation in Korea have great influences on the variation patterns and the appearances over a ten-day period during the summer precipitation. The purpose of this paper is to induce variation patterns over a period 10 days during the summer precipitation, clarify the variations of their space scales, and study the subdivision of precipitation regions in Korea according to the combinations of precipitation amounts and variation pattern during the period, using the mean values during the years $1991\~2003$ at 78 stations in Korea. The classified precipitation of a period of 10 days of summer precipitation, and the principal component vector and the amplitude coefficient by the principal component analysis were used for this study. The characteristics of variation pattern over the ten-day period can be chiefly divided into two categories and the accumulated contributory rate of these is $64.3\%$. The variation patterns of summer precipitation during period of 10 days in Korea are classified into 9 types from A to K. In addition, regional divisions of summer precipitation in Korea can be classified into 17 types.

  • The purpose of this study was to analyze the change trajectory and latent class types of self-esteem in first to fourth grade elementary school students. For the purpose, the Korean Children's Panel data were analyzed using potential growth model and the growth mixture model. As the results, the linear change model was selected as the most appropriate model. The change trajectory was found to increase slightly as the grade increased. In addition, four latent class groups were derived through: 'high level-maintenance,' 'low level-increase,' 'high level-decrease,' and 'low level-maintenance.' Most children were in the 'high level-maintenance' group, followed by 'high level-decrease,' 'low level-increase,' and 'low level-maintenance' groups. Therefore, based on the results of the study, we suggest that educational institutions and local communities pay attention to trends in elementary school students' self-esteem and provide appropriate support for students in each class.

  • The purpose of this study was to find a relationship between eating behavior, dietary self-efficacy and nutrition knowledge by comparing these items in elementary school students according to food service type. The survey was made through a questionnaire from 759 students in the 6th grade of elementary school in 39 Gangwon Province. The average score of eating behaviors according to food service type was highest for urban type, followed by agri-fishery type, and finally remote island and country type, for the questions asking about the application of nutrition knowledge and the frequency of eating out. The average score of nutrition knowledge according to food service type showed significant differences for the questions about eating snacks before going to sleep and weight increase as well as calorie comparisons between foods. For the correlation of eating behavior, dietary self-efficacy and nutrition knowledge, the agri-fishery type showed positive in all of the three items with significant differences. In the remote island and country type, there was a positive relationship between nutrition knowledge and dietary self-efficacy, and between eating behavior and dietary self-efficacy. However, there was no significant difference of correlation between nutrition knowledge and eating behavior. In order to confirm the predictable variables for eating behavior, a regression analysis was made by injecting variables in every stage with independent variables of dietary self-efficacy and nutrition knowledge, which showed a significant relationship with eating behavior. The results showed that, in the urban type, dietary self-efficacy and nutrition knowledge affected the eating behavior and, in the agriculture type and the remote island and country type, only dietary self-efficacy affected the eating behavior.

  • The purpose of this study was to analyze the lower extremities joint moment pattern by two types of service motion in tennis pinpoint and platform stance. Seven skilled high school tennis players participated, and the kinematics were recorded by the Vicon motion analysis system. For the gathering and analysis of the data Workstation, Bodybuilder and polygon were used. joint moments and Ground Reaction Forces for the phases involved were analyzed with the following results. There was a different moment pattern for the lower extremities between the two serve motions. For the platform stance there was only a large dorsal flexion moment but for the pinpoint stance there were other large moments. The flexion and maximum moment of the lower extremities occurred at the point of change from back swing and to the forward swing motion. Therefore, this data provides evidence that there is a high risk of injury at this point.

  • 경영환경 변화와 필요성에 대한 인식이 높아져 많은 기업들이 정보화 투자를 수행했지만 여전히 중소기업에게는 비용 부담, 투자성과의 불확실성 등으로 인해 미진한 면이 없지 않다. 본 연구에서는 중소기업에 대한 실태조사를 통해 BSC에 기반하여 정보화에 따른 성과를 측정하고, 정보화 투자 유형에 대해 분석하였다. 그 결과 현재 가장 많은 투자가 이루어진 영역은 회계, 마케팅, 영업 관련 분야 순이며, 투자규모로는 제품개발 부문에 가장 많은 투자비가 소요되고 있는 것으로 나타났다. 투자 유형을 보면 9개 분야에 걸쳐 모두 정보화 시스템을 운영중인 기업은 3%에 불과하고 6.92%는 정보화 시스템이 하나도 없는 것으로 조사되었다. 각 분야별 정보화 시스템 운영을 통해 모두 성과가 유의할만한 차이를 나타내었으나 마케팅/서비스 분야는 그렇지 않은 것으로 나타났다. 또한 현재 중소기업들이 가장 선호하는 정보화 시스템과 이들이 어떤 패턴으로 정보화에 대한 투자를 진행해왔는지를 살펴볼 수 있었다. 이러한 시사점을 통해 향후 중소기업 정보화를 지원하는데 있어서 보다 더 효과적인 경로를 유추할 수 있고, 정책효과를 극대화하는데 일조할 수 있을 것이다.

  • This study demonstrates the gender difference in the factors that affect job changes and the resulting wage changes in the recent Korean labor market. By using the KEAPS (2003-2007), we found that male workers uniquely tend to stay longer at their current jobs when they have families to support. After controlling self-selection bias, we also found that wage changes resulting from switching jobs differ between male and female workers during this studied period.

  • The purpose of this study was to suggest a grounded theory on the process of undergraduate students' generating pattern-knowledge about scientific episodes. The pattern-discovery tasks were administered to seven college students majoring in elementary education. The present study found that college students show five types of procedural knowledge represented in the process of pattern-discovery, such as element, elementary variation, relative prior knowledge, predictive-pattern, and final pattern-knowledge. Furthermore, subjects used seven types of thinking ways, such as recognizing objects, recalling knowledges, searching elementary variation, predictive-pattern discovery, confirming a predictive-pattern, combining patterns, and selecting a pattern. In addition, pattern-discovering process involves a systemic process of element, elementary variation, relative prior knowledge, generating and confirming predictive-pattern, and selecting final pattern-knowledge. The processes were shown the abductive and deductive reasoning as well as inductive reasoning. This study also discussed the implications of these findings for teaching and evaluating in science education.
