Objectives : The purpose of this study is to examine sleeping patterns and diet patterns of the children in day-care centers in Seongdong-district and to find out the relationships between those two patterns and children growth. Methods : 686 day-care center kids participated in the examination. We measured their heights and weights. We also conducted a questionnaire survey (of them) on their sleeping patterns and diet patterns. Based on the findings, we have analyzed correlations of the factors. Results : 1. We have interviewed 686 children in day-care centers in Seongdong-district. Substantial survey was conducted to 672(14 kids didn't go through regular medical checkups). Their age ranged from 4 months to 120 months and weights covered from 6.20 kg to 50.80 kg with the average of 16.97kg. Their height ranges were from 70.4cm to 140.6cm and the average was 100.76cm. 2. The survey results showed that birth-height affects children's current height. The results from the group of age over 25months and the group covering 2 to 6 years indicated that birth-height affected the current height as well. However, the result from the age group over 37 months showed that birth-height didn't relate to the current height. 3. Results from questionnaires on sleeping patterns indicate that children sleeping longer are taller than the other. Results of other questionnaires showed no substantial relations to height. 4. Results from questionnaires on diet patterns, cold food eating habit affects growth. Conclusions : According to the results above, sleeping patterns substantially affects the growth. In order to find out, however, the specific relations between them, further research would be necessary.

A rectangular coaxial line is mainly utilized as a transition structure from a coaxial line to a rectangular waveguide. A TEM cell is also widely used to measure the EMC characteristics of a DUT. In order to understand the operations of a rectangular coaxial line and a TEM cell, it is essential to analyze the dispersion relations of a rectangular coaxial line and a TEM cell. In this paper, we present simple yet accurate dispersion relations of the TE and TM higher modes based on the TEM mode. Manipulating a mode-matching technique and a Green's function approach allows us to obtain the analytic dispersion equations of a rectangular coaxial line and a TEM cell. In our approach, a rectangular coaxial line is divided into four L-blocks and its electromagnetic fields representations are easily obtained with a superposition. To verify the convergence of our dispersion relations, we perform numerical computations and compare our results with those of FDTD.

Purpose: 'The purpose of the present study was to understand students' experiences from their standpoint, to identify relevant variables and to examine into their relations by analyzing and describing what phenomenon 'nursing students' visiting ambulatory bathing service' is, what are the reasons for the phenomenon, and what interactions are in the phenomenon. Method: The subjects were thirteen students. Data were collected through in-depth interviews and analyzed by Strauss and Corbin's analysis method. Result: With regard to ambulatory bathing service, participants responded 'lack of education', 'inexperienced personal relations' and 'disappointment with recipients families'. They recognized 'burden' and 'compassion'. The intensity of generated 'burden' and 'compassion' was determined by volunteering persons, the degree of health care service, recipients' response and interaction of climate. When 'burden' and 'compassion' were generated, participants selected their own coping strategies. Strategies in the situation of 'burden' and 'compassion' were significantly influenced by 'burden' and 'compassion' and structural situation - 'mutual relation structure,' 'volunteers' capability,' 'the degree of volunteering guidance,' 'community participation,' 'recipients' environment,' 'information sharing,' 'special vehicle equipment' and 'economical burden.' Strategies include' service training,' 'receiving volunteering training,' 'preliminary service preparation,' 'volunteering.' 'connection to local medical center,' 'intention,' 'information sharing,' 'passive response to recipients' appreciation' and 'the understanding of publicity'. The results of selected 'burden' and 'compassion' are described with 'worthiness' and 'cohesion' as follows. Conclusion: This study is significantly meaningful in that it examined bathing service welfare in its initial stage. There are not much outcome from previous studies. However. it is meaningful that this study intended to develop theories on the nature of experiences and the relations among concepts derived from the visiting ambulatory bathing service process of nursing students. Professors who taught social volunteering in universities understood the experience of nursing students who did the visiting ambulatory bathing service. Consequently, professors will provide an effective instruction to enable these students to carry out visiting ambulatory bathing services efficiently in order to meet demands when they conduct the services. For the volunteering service activity in major-related fields among college students' social volunteering activities, they recognized the necessity of systematic education and preparation.

Since July 7 mutual declaration in 1988 which is a landmark for South-North Korean relations, Inter-Korean Trade has been set out. During the period, the Inter-Korean Trade has been ups and downs depending on the Inter-Korean relations and economic situation of both countries. South Korea became one of the major three trading countries of North Korea's trading partners in 2000, when the sum of annual trade volume reached the record 425million US dollars. A rapidly increasing number of countries including North Korea are developing national policies and strategies to promote the digital economy, recognizing the potential benefits of e-business as an engine of growth and development. However, the trade structure of South-North Korea remains very simple in terms of its contents. Furthermore trade procedure many limitations especially electronic commerce in North Korea has many obstacles to working properly. The information in Inter-Korean trade cannot be shared in common. South Korean firms have suffered repeatedly trial and error and excessive competition took place among South Korean firms. Institutional inertia related to mutual trade, political and military Impacts on Inter-Korean economic relations, abnormal industrial structure of North Korea and insufficiency of SOC could be mentioned as major problems in Inter-Korean trade as well. Several measures should be taken in order to cope with those problems. First of all, South Korean government should provide valuable information to business firms about North Korean economy and business environments. It is suggested that forums related to inter-Korean trade hold in regular base between South and North Koreas and establish the system of business information sharing. Second, the government should improve various laws and regulations to respond to the realistic needs of inter-Korean trade. That is, detailed measures should be taken to guarantee investment in electronic commerce. Third, it is desirable to start with the mutual agreement between South and North Korea.

The stream morphological characteristics of a watershed play a significant role in the analysis of rainfall-runoff relations in a river basin and a quantitative description of these characteristics is essential for determining the appropriate values of physical parameters of a watershed which usually are input data for rainfall-runoff simulation models. In this study the stream morphological characteristics of the Gab River basin, which is one of the three major tributaries of Geum River, was determined quantitatively by the Horton-Strahler's method. The result showed that the Gab River System was developed very closely to the patterns generally described by the laws of Horton. The basic relations concerning the morphological characteristics deriveed in this study are the relations of stream length, and average stream slope, the stream length-drainage area relation, relative height-relative drainage area relation, and the relation between the proportional stream order and drainage area. No correlation analysis was possible between the morphological parameters and the streamflow due to non-existence of the stage gauging stations on the Gab River System.

The purpose of this research was to apply and conduct a class with Gordon’s Creative Problem Solving Method(Synectics) to the area of ’human development and family relations’among male students in a jr. high school. Subject matters which were appropriate for applying Gordon’s Creative Problem Solving method were selected from ’human development and family relations’area, with problem circumstances set to reflect to the highest degree the interests of individuals and families. An 8 hour teaching instructional guide was constructed with $\boxdr$strategy 1$\boxul$of Gordon’s Creative Problem Solving method in order to solve creatively the established problem. This was practically implied to 70 students(each class had 34 and 36 students respectively) in K middle school located in Seoul. The period of this application was for 3 months during March through May of 1999. The perception of this method was examined by the teachers and students through open-ended questions. The record of perception showed that 56 students out of 70(with no response from 5 students) through that the class done by the creativity problem solving method was good. The majority of reasons mentioned for the positive answers were ’being able to receive different thoughts which were unusual of daily life’. In addition the students who participated in the class were able to foster a joint experience which improved their understanding of relationships and sens of community. moreover students who did not do well n the class or were diffident were encouraged to participate which in result showed that there was even an internal effect.

Purpose - The purpose of this study is to investigate economic variables which have impact on the prices and returns of preferred stocks and to provide investors, underwriters, and policy makers with information regarding correlations and causal relations between them. Design/methodology/approach - This study collected 98 monthly data from Korea Exchange and Bank of Korea. The Granger causal relation analysis, unit-root test and the multiple regression analysis were hired in order to analyze the data. Findings - First, our study derives the economic variables affecting the prices and returns of preferred stocks and their implications, while previous studies focused mainly on the differential characteristics and related economic factors between common and preferred stocks. Empirical results show that the significant variables influencing the prices and returns of preffered stocks are consumer sentiment index, consumer price index, industrial production index, KOSPI volatility index, and exchange rate between Korean won and US dollar. Second, consumer sentiment index, consumer price index, and industrial production index have significant casual relations with the returns of preferred stocks, providing market participants with important information regarding investment in preferred stocks. Research implications or Originality - This study is different from previous studies in that preferred stocks themselves are investigated rather than the gap between common stocks and preferred stocks. In addition, we derive the major macro variables affecting the prices and returns of preferred stocks and find some useful causal relations between the macro variables and returns of preferred stocks. These findings give important implications to market participants, including stock investors, underwriters, and policy makers.
