Purpose : This study was undertaken in order to find out the actual correlation between skipping breakfast of school-aged children and their mothers. Method : The subjects of this study were 724 children and their mothers. The subjects were selected from two schools out of six offices of education in Busan between December 1 and December 20, 2002. The collected data was analyzed through real numbers, percentage, mean and standard deviation, cross tabulation, $\chi^2$-test, t-test, F-test, Scheffe-test and Pearson correlation coefficient using the SPSSWIN 11.0. Results : The results of this study are summarized as follows. 48.6% of children skipped breakfast while 54.7% of mothers skipped breakfast. The case that both children and mothers skipped breakfast were 37.1%. The correlation of children's skipping breakfast and their mothers characteristics was statistically significant(r=.288(p<0.001). There was relationship between the life styles of children and their mothers, but there was no relationship between life styles and the frequency of skipping breakfast. Conclusion : children are affected by or depend on their mothers eating habits and other tendencies in daily life.

Purpose: This study investigated the correlation between standing balance and head-forward posture in adolescents. Methods: The participants in this study were 15 female adolescents. We took photographs of the participants' craniovertebral angle with a digital camera to determine the degree of head-forward posture. Standing balance was evaluated using the 30-second Romberg test of BT4. The measurements were taken on a stable-support surface and on an unstable-support surface using a balance pad. The data measured in this study were analyzed using SPSS version 23.0, and the statistical significance level α was established as 0.05. Pearson correlation coefficient analysis was performed to identify the correlation between the degree of head-forward position of the participants and their balance ability. Results: When we measured 30 seconds of the Romberg test, we observed that, with their eyes open, the participants' head-forward posture and balance were not correlated. However, with their eyes closed, there was a strong correlation between the forward position of the head and the balance ability, which declined as the head position increased. Conclusion: Adolescents with severe head-forward posture exhibited problems with balance in posture control with closed eyes when visual information was not available. It can be inferred that an abnormality occurs in proprioceptor sensation due to their habitual head-forward posture. Education on correct posture and preventive activities should be recommended to improve the health of such adolescents and avoid possible future problems of physical deterioration.

The purpose of this study is to provide useful information which will aid in the promotion of nutritional policy in the Korean rural area which are derived from a survey of intake and source of protein in some Korean rural adults and the correlations between their protein nutrition and various nutrients, the uses of tobacco, alcohol, coffee, etc. The survey was conducted from July, 24 through July, 18, 1989. The healthy subjects were 45 males(average age 42.3, average BMI 22.1kg/m2) and 55 females (44 years, 21.2 kg/m2) residing in Sungjoo Kyun, Chulanam-Do, Korea. The subjects were examined for the anthropometric, food Intake and food habits. Their daily diets were measured by 24-hr recall method. The results can be summarized as follows : The daily mean protein intakes of male and female subjects were 9595 of RDA(66, 5g) (16. 7% of total food intake per day) and 102.3Bh of RDA(61g) (14.8% of total intake per day) respectively. The order of sources of animal protein in all subjects was fish(47.9%), meat(29.8%), milk (12%), and egg(10.3%). Among protein sources the intake frequencies of fork and chicken were higher than those of others. The protein nutrition of the subjects showed positive correlations with energy and fat, carbohydrate, fiber at the level of significance of 1%. The protein nutrition of the male subjects showed no correlation with age, BMI, uses of alcohol, coffee, medicine, but the plant protein nutrition showed a positive correlation with smoking and exercise(at 5%). And the protein nutrition of the male subjects showed no correlations with uses of tobacco, alcohol, coffee, medicine and their opinion of their present state of their health, but the age of the male subjects showed negative correlations with milk(at 1%) and egg(at 5%). In conclusion, the daily protein Intake was good and the main sources of animal protein were fishes in rural adults. The protein nutrition of the subjects showed a correlation with energy, fat, carbohydrate and in the case of female, milk and egg intakes showed the negative correlation with age.

The success of a construction project hinges on the effective and efficient management of human resources. The stress of human resources is directly related with work performance, and as such, should be managed to improve work performance. This study examined the correlation between job stress and job satisfaction among building construction project managers. A questionnaire to measure work performance was created by referring to the Korean Occupational Stress Questionnaire Short Form developed by the Korean Occupational Safety & Health Agency, as well as a previous study. The mean job satisfaction score of field managers was 3.6, which suggests that they are generally satisfied in their current job environment. A Pearson's correlation analysis showed that the field managers that were satisfied with their job had less job stress. These results could be used for the effective management of construction site managers and to improve their job performance in the field.

Anti-aging is one of the key words to have characterized Korean society, and Korean adults in their 40s and 50s are very interested in this word. In this study, their cognitive ages and body images which are expected to have been influenced by anti-ageing were determined and correlation between them was examined. A survey was conducted and 368 of 500 questionnaires were used in data analysis. Data were analyzed by descriptives, factor analysis, reliability analysis, correlation analysis, and multiple response analysis through SPSS 12.0. The results are as follows. First, the cognitive ages of Korean adults in their 40s and 50s showed to be 37.5 years old which are 9.1 years old younger than their average actual ages. Second, their attitudinal body images appeared to be composed of appearance orientation and appearance evaluation, and appearance orientation represented to be a little higher than appearance evaluation. In addition, it showed that the correlation between cognitive ages and the attitudinal body images was low and negative. Third, people in their 40s and 50s revealed to think good health and impression as ideal body images. It was found that they regarded a face as the most important body part for ideal body images and were sensitive of their weight. Forth, correlation between cognitive ages and variables of ideal body images was identified to be significant in 4 variables which are slender, shapely and slim figure and good body proportions. In conclusion, it was shown that Korean adults in their 40s and 50s recognized themselves to be 9.1 years old younger and, the younger they perceive themselves, the younger body images they want. Also, it could be confirmed that anti-ageing is a megatrend in Korean society.

The purpose of this research is to identify antecedent variables and outcome variables of the empowerment in clinical nurses, and to suggest managerial strategies for increasing their empowerment. Data were collected from October 12 to 18, 2000 through questionnarie taken by 566 nurses in 3 general hospitals. The 5 structured instruments were used for collecting the data : Spreitzer's Items Measuring Empowerment, Bass's Multifactor Leadership Questionnaire-1, Moorman's Equity of rewards scale, Mobley's turnover intention scale, and the Organizational Commitment Scale developed by Mowday, Porter & Steers. The data obtained were analyzed using frequency, percentage, mean, standard deviation, t-test, one-way ANOVA, Scheffe' test, Pearson's Correlation Coefficients, Factor Analysis, Cronbach's alpha Coefficients, Multiple Regression. The results were as follows; 1. Head nurse's transformational leadership showed an positive correlation with empowerment(r=.304, p=.00). Regression coefficient between transformational leadership and empowerment was significant(${\beta}=.326$, p=.00), However, there was no a correlation between equity of rewards and empowerment. 2. The general characteristics of nurses were significant differences with empowerment. As for position, age, working experience, and education background showed significant difference with empowerment(F=10.979, 11.224, 6.812, 5.411, p<.01). 3. Empowerment showed a positive correlation with organizational commitment and a negative correlation with turnover intention (r=.387, -.274, p=.00). Regression coefficient between empowerment and organization commitment was significant(${\beta}=.365$, p=.00). In conclusion, the more head nurse took the transformational leadership, the higher nurses perceived empowerment. The higher their empowerment level, the higher organizational commitment they perceived. On the contrary, the higher their empowerment level, the lower their turnover intention. Therefore, in order to increase nurses' organization commitment and decrease their turnover intention, their empowerment should be increase. And it is necessary to develop the transformational leadership of head nurses so as to increase empowerment.

Objectives : This study was to examine the social value of dental hygienists, their values about the health system and the relationship of all the related variables. Methods : The subjects in this study were 205 dental hygienists who worked in dental clinics and hospitals on Seoul. A survey was conducted from August 12 to October 15, 2010. The questionnaire consisted of nine items about general characteristics, two items about social values and 11 about values of the health system. The items related to social values and values of the health system were prepared by translating the items used in David et al's study, and the Cronbach alpha coefficient of those items respectively 0.80 and 0.76. Results : The dental hygienists got 3.94 in social values, which was above the average. In terms of values about the health care system, their values of the treatment delivery system(3.92) rated highest, followed by values of patient rights(3.79) and values of institutional restrictions(3.25). Their socal values had a closest positive correlation to their values of the treatment delivery system, and their values of patient rights had a strong positive correlation to those of the treatment delivery system and was positively correlated to those of institutional regulations as well. And there was a positive correlation between their values of the treatment delivery system and institutional regulations(r=.276). Conclusions : The above-mentioned findings illustrated that the social values of the dental hygienists had a positive correlation to their values of the health system. Therefore the kinds of educational programs that help dental hygienists to build their social values and values of the health system should be developed to improve their job efficiency as oral health experts.
