  • Objectives: The purpose of this study was to identify the effects of sleep quality and occupational stress on health-related quality of life among a university's security workers. Methods: 128 security workers voluntarily participated in the study. The survey asked demographic, health related, job related factors, the Korean Occupational Stress Scale Short Form(KOSS-SF), sleep quality questionnaire, and 12-Short Form Health Survey version 2.0(SF-12v2). The data were analyzed by using descriptive analysis, t-test, ANOVA, multiple linear regression, and multiple logistic regression. Results: The interrupted rest time was significantly negatively related to occupational stress. The occupational stress significantly affected sleep quality. The significant variable affecting Physical Component Score(PCS) and Mental Component Score(MCS) was sleep quality and occupational stress, respectively. Conclusions: HRQOL was founded to be affected by occupational stress and sleep disorder among the security workers. Based on this study, we suggest that the management of both occupational stress and sleep quality is crucial to improve the HRQOL.

  • Purpose: This study was conducted to find ways to improve foodservice quality and satisfaction of middle school students in school lunch service. Recognition of concerns about school lunch and quality attributes was evaluated by gender. And we tried to investigate quality attributes which could affect degree of foodservice satisfaction by gender. Methods: Two hundred students from each of 6 middle schools (3 schools in urban and 3 schools in rural) in Gyeonggi Province were surveyed using self-developed questionnaires. Total of 1,103 questionnaires (male 556 and female 547) were collected and data were analyzed using descriptive analysis, t-test, cross table and stepwise multiple regression by SPSS 11.0. Results: There were not significant differences in average importance scores (male 4.09, female 4.06) and average performance scores (male 3.36, female 3.30) of quality attributes between middle school boys and girls. But there were significant differences in 7 and 6 of 25 quality attributes in evaluating importance and performance respectively by gender. There was not a significant difference (male 3.13, female 3.24) in degree of foodservice satisfaction by gender. But there were significant differences in the distribution of satisfaction. Stepwise multiple regression analysis showed that degree of satisfaction was influenced by a taste of food, quick complaint handling, providing favorite foods, and food hygiene in male students (F=$51.1^{***}$, adjusted $R^2$=.265). Degree of satisfaction was influenced by a taste of food, providing favorite food, proper meal prices, providing a wide variety of food in female students (F=$91.4^{***}$, adjusted $R^2$=.399). Conclusion: We found out that there were significant differences in quality attributes when evaluating importance and performance and in quality attributes which could affect foodservice satisfaction by gender.

  • This study was performed to assess the nutrient intakes and diet quality of rural middle school students provided with and without the national school lunch program(NSLP). The data on dietary intakes were obtained by using food record method questionnaires which were collected from 340 rural middle school students provided with(n=177) and without (n=163) NSLP. Diet quality was accessed by NAR(nutrient adequacy ration), MAR(mean adequacy ration), and INQ( index of nutritional quality). Total energy intakes of the boys were 2123 kcal with NSLP and 1857 kcal without NSLP. Total energy intakes of the girls were 1913 kcal with NSLP and 1814 kcal without NSLP. Phosphorus, vitamin A, vitamin E, ascorbic acid, thiamin, riboflavin, and niacin intakes were above the RDA in the NSLP group. For those without NLSP, phosphorus, vitamin E, thiamin intakes were above RDA, however, calcium, iron vitamin A, vitamin $B_6$ were less than the RDA. The mean adequacy ration(MAR), an index of dietary quality was 0.69(with) 0.62(without) for males and 0.62(without) for females The indexes of nutritional quality(INQ) were over 1 for most nutrients except calcium, vitamin A, vitamin B$_2$ and zinc. The study showed that total daily energy and nutrient intakes were significantly higher in students provided with than those without school-lunches.

  • Although quality metrics for 2D video quality assessment have been proposed, the quality models on stereoscopic video have not been widely studied. In this paper, a new objective video quality metric for s tereoscopic video is proposed. The proposed algorithm consider three factors to evaluate stereoscopic video quality: blocking artifact, blurring artifact, and the difference between left and right view of stereoscopic vide o. The results show that the proposed algorithm has a higher correlation with DMOS than the others.

  • This study investigated the effect of home environment quality and fathers' parenting participation on school readiness of preschool children. The subjects were 101 5-years old children, mothers and teachers at child care centers located in the Gyeonggi area. Home environment quality was measured using a 'Korean Home Environment' questionnaire. Parenting participation by fathers was measured by 'Scale for Productive Roles of Fathers of Children in Their Early Childhood.' Lastly, the children's school readiness measured the 'School Readiness Inventory.' Collected data were analyzed using t-test, correlation analysis, and hierarchical multiple regression. The results of the study showed that the school readiness of preschool children differed by gender. The score of girls' school readiness was higher than boys' school readiness. Such difference was apparent in the school readiness areas of general knowledge, mathematical knowledge, and adjustment. There was a positive correlation between age and the school readiness of preschool children. An increase in children's age also increased school readiness in the areas of linguistic knowledge, mathematical knowledge, and adjustment. Home environment quality and fathers' parenting participation directly influenced the school readiness of preschool children. The pattern of the results suggests that a desirable home environment and fathers' contribution in the family for children are critical components to prepare preschool children for elementary school.

  • Objectives: This study aims to identify the effect between high school students' recognition of mental health on sleep quality to present basic data for better health. Methods: The study used data obtained through the 2007 online research on adolescents' health behaviors, targeting a total of 35,228 high school students (18,628 of male students and 16,600 of female students). Results: Seventy six point ninety six percent of the male respondents and 79.67% of female respondents answered their sleep quality was not satisfactory. The subjects who had stress showed significantly lower quality of sleep than those who answered they had no stress. For female students, those who answered they had intention to suicide had significantly lower quality of sleep than those who answered they did not have, but for male students, there was no significant relations between them. There were no significant relations between sense of dispair and sleep quality both for male and female subjects. Conclusion: Factors of mental health related with sleep quality were stress and intention of suicide. The more they had stress and intention of suicide, the significantly lower sleep quality was. Therefore, in order to improve sleep quality of high school students, it is suggested that management programs based on education and counselling with experts should be provided and further studies on other mental health factors and sleep quality should be conducted.
