Purpose: The purpose of this study was to identify the relationship between eating disorders, physical symptoms, depression and health locus of control. Method: The research design was a descriptive study done by using a constructive self-report questionnaire. A total of 464 elementary school girls were measured. The instrument was a constructive questionnaire that consisted 136 items. The subjects were divided into 4 groups according to the Body Mass Index (BMI). Data analysis was done by SPSS/WIN Programs using frequency, percentage, mean, SD, ANOVA, Pearson correlation coefficient, and stepwise multiple regression. Result: The score of eating disorders differed significantly by BMI : the score was highest in the group of obese students(F=4.208, P=.015). Stepwise multiple regression analysis revealed that the most powerful predictor of eating disorders was BMI. Conclusion: These results indicate that Korean elementary school girls need more education and counseling on diet. Also, we should take systematic efforts to reestablish the social standard of beauty to promote normal growth development.

This paper wanted to test the reality of English schwa by phonetic and phonological methods. Phonetically it wanted to see acoustic evidence of the relationship between the full vowels and their reduced vowels in the unstressed positions. Phonologically it wanted to prove how systematic the schwa sound is by the constraint-based grammar. As a result, the schwa phenomenon in English was supported both phonetically and phonologically. In the phonetic analysis no relationship Was found in the distribution of the F1 and F2 of the full vowels and their reduced vowels in the unstressed syllables of the derived words. The reduced vowels tended to converge into a target of F1 516 and F2 1815. The view that the schwa sounds have a target was supported. On the phonological side the constraint-based tableau produced the successful output by using FAITH (V), (equation omitted)V, FAITH V[-BACK+HiC], V[-Low, -TNS]#, REDUCE V[-STR, -TNS] as constraints. No ranking was found. Any violation of the constraints ousted the candidates.

This study reviews existing research on the measurement of and the relationship between political diversity and political participation. It addresses the inconsistency in the arguments of existing studies researching the influence of political diversity on political participation. It attempts to find the cause in the variety of approaches to conceptualize and operationalize the two variables. As the measure of political diversity, political network heterogeneity and network attributes are discussed in detail in specific relation to political participation. As for political participation, an in-depth analysis of various ways to understand different forms of political involvement is presented. Implications for public opinion research are discussed.

This paper is to experimentally investigate the effect of the through-flow and grazing-flow on the absorption performance of a perforated plate system. The experiment is performed through the systematic change of the through-flow velocity, grazing-flow velocity, incident sound pressure level, and the geometrical parameters such as the porosity and hole diameter. From the experimental results, it is found that for the nonlinear relationship between the acoustic resistance and incident sound pressure level there is no influence of the through-flow on the absorption performance, but fur the linear relationship between them there is a strong dependence of the absorption performance on the through-flow velocity. It is also shown that the absorption performance is controllable by changing the porosity and hole-diameter in size.

Since Capital Asset Pricing Model(CAPM) was proposed in the early 1960s by William Sharpe(1964) and John Lintner(1965) researchers have investigated the validity of the model. The results of empirical researches do not show that expected returns of stocks seem to be determined solely by systematic risk of the stocks as precicted by CAPM. In this paper the relationship between transaction volume and expected returns of stocks was investigated. Empirical cross-sectional analysis about the data collected from Stock Market of Korea Exchange shows transaction volume and variability of stock returns play an important role in pricing assets. The well-known variables which were used traditionally to explain the differences of expected returns among stocks such as the size and beta of a stock seems to be unimportant in pricing assets.

This study aims to present suggestions on the causes and effects between internal marketing and customer-oriented trends of social welfare halls based on the issue that internal marketing should be activated based on previous studies on the relationship between internal marketing and customer-oriented trends. For this purpose, as a result of analysing the research hypothesis through a questionnaire, this study has meaning in that it supported the results of previous studies on internal marketing and customer-oriented trends as theoretical suggestions and analysed the relationship between internal marketing and customer-oriented trends. It was politically suggested and emphasized that internal marketing is needed in social welfare halls and to encourage social welfare workers to be customer-oriented, components of internal marketing should be established in an organic and systematic manner.

Along with the evolution of wireless internet environment, information services in mobile internet are being explosively increased. However, due to the high expense for the use of those services, it is not easy to collect the devoted customers. In order to overcome the adverse conditions, the service should be supported by a strategic application system which facilitates easier and fast service for customer's information needs than that of traditional on-line internet. In this paper, we investigate the strategy how to provide the information service under the customer satisfaction, and also consider some ways of personalization of information service and information provision in real-time. As a result of the works, we develop a system, MoSA-CRM(Mobile Service Application based on CRM) to support customer-oriented information service. We believe that the MoSA-CRM system can provide some benefits for information providers in mobile e-commerce market such as flexibility in business strategy, systematic customer relationship management, and growth in financial ability.

Objectives : The purpose of this study was to examine the relationship between the infection control education experiences of dental hygienists and the state of their infection control. Methods : The subjects in this study were the dental hygienists who worked in Seoul. The relationship of their infection control education experiences to their gender, marital status, academic credential, workplace, length of service, infection control implementation, experience of being exposed to infection, way of coping with it, hand washing, use of personal protection devices and equipment management was analyzed. Results : It is found that the variable to affect the state of infection control was educational experiences about handpiece water pipe management, ultrasonic scaler water pipe management and three-way syringe water pipe management. Conclusions : Dental hygienists who are one of major dental personnels should receive systematic education on infection control to acquire accurate knowledge to ensure the successful prevention of cross infection.

Objectives: The purpose of this study was to investigate the relationship between oral health awareness symptoms and academic stress in some high school girls and to find out existing improvement plans. Methods: This study conducted a self-reported survey on 303 high school girls from four high schools in Jeollabuk-do. Results: Higher academic performance, poor subjective oral health, awareness of dental caries, awareness of jaw joint disease, awareness of discomfort during chewing, and awareness of tooth pain significantly increased overall admission stress. The most influential factors were dental pain symptoms, followed by subjective oral health and dental caries symptoms. Conclusions: Effective measures to help high school girls cope with academic stress, a systematic school oral health policy, and practical health promotion activities are necessary to improve their oral health.
