The purpose of this study was to set up the basic model to monitor the health status of the middle and high school students in the adolescent period, as well as to provide the fundamental data which might serve as the new standards for their better health maintenance and promotion. The collected data comprised the characteristics of the subjects in the three different fields of life such as school, family and everyday, which could affect their physical fatigues, and they were analyzed to determine the factors of significant influence upon their physical fatigues and to reveal their relativity. A total of 5,954 students at 6 boys' and girls' middle and high schools in Taejon City completed self-administered questionnaires(to measure Health Practice Index and others) asking about each of three life domains during the period March through June, 2000. The key study results were as follows; 1. The middle school students showed more subjective symptoms of fatigue which may be a marker reflecting physical health status, than the high school students. The higher scores were associated, based on school life, with the groups who were boys, who were in lower school grades, who achieved better academic performances and had better relationship with friends. 2. As for family life, the higher scores were in the groups whose financial conditions were better, whose parents showed more interest to their children, whose sense of satisfaction with family life was higher, and whose health status was better. 3. As for life styles, the individuals showed the higher scores in the groups who had breakfasts daily, who didn't have inter-meal snacks, who took regular exercises, who didn't smoke and drink than, their counterparts. 4. The higher level of fatigue was associated with the groups whose health conditions were good, who are satisfied with school life, who were boys rather than girls, who are satisfied with family life, who didn't have inter-meal snacks, who were in good relationship with friends, who achieved greater academic performances, who took regular exercises, who didn't smoke, and whose parents showed more interest in their children.

Purpose: The purpose of this study is to analyze the correlation between obesity stress, self-esteem, and adaptation to school life according to body mass index of elementary school students in higher grades and to provide basic data for the development of health education programs. Methods: A convenience sampling method was used to select four elementary schools. Self-reporting questionnaires were distributed to the subjects to collect data, which were then analyzed using the SPSS 18.0 program. Results: The higher the obesity index, the more obesity stress the students experienced. Second, the lower the level of obesity, the higher both self-esteem and the level of adjustment to school life were. There was a meaningful correlation between obesity stress, self-esteem, and adjustment to school life. Conclusion: The study results are expected to be useful in serving as a basic material for the development of programs that can improve students' adjustment to school life and self-esteem while reducing their stress caused by obesity.

The objective of this study is to investigate the perception and satisfaction of elementary and middle school students on free school food service. We surveyed education related to school food service, concerns about food ingredients, perceptions of free school food service and satisfaction for the quality of the school food service. The investigation is classified into two groups, schools that operate as a food service center or those that do not. Those who are provided food ingredients by school food service centers are educated about the agricultural products' country-of-origin and their environment-friendly food service. The more individuals are educated of the foods' county-of-origin and environment-friendly food service the more they will have a higher concern of the food materials and subsequently a higher satisfaction for the quality of school food service. School food service centers managed directly by the local government would probably receive higher satisfaction than those consigned to a private sector. The results of this study will be meaningful to establish policies on school food service and school food service centers.

This study was conducted to compare the nutrient content of rice-based meals and wheat-based meals. The subjects consisted of elementary school children, middle school students, high school students, college students and adults living in the Miryang and Daegu area. A dietary survey was conducted using a 24-hour recall method and data were collected from 941 subjects. Nutrient contents were analyzed by CAN Pro. All nutrient contents in rice-based meals, except vitamin B2, were higher than those in wheat-based meals. But lipid and cholesterol contents of wheat-based meals were higher than those in rice-based meals. Comparing age groups, all nutrient contents obtained from rice-based meals, except vitamin B group, were higher than those in wheat-based meals in all age groups except the adult group. In the adult group, protein, fiber, vitamin A, niacin and vitamin C were consumed higher from rice-based meals, but energy, lipid, calcium, iron, vitamin B and cholesterol were consumed higher from wheat-based meals. lipid and cholesterol contents of wheat-based meals were higher than those of rice-based meals in all age groups, except elementary school children. When compared the nutrient intakes of Korean RDA, major nutritional problems of each age groups were due to the inadequate intakes of calcium and iron. And all nutrient contents, except vitamin B group, in wheat-based meals were very low in every age group.

We perform the task of video object segmentation by incorporating a conditional random field (CRF) and convolutional neural networks (CNNs). Most methods employ a CRF to refine a coarse output from fully convolutional networks. Others treat the inference process of the CRF as a recurrent neural network and then combine CNNs and the CRF into an end-to-end model for video object segmentation. In contrast to these methods, we propose a novel higher-order CRF model to solve the problem of video object segmentation. Specifically, we use CNNs to establish a higher-order dependence among pixels, and this dependence can provide critical global information for a segmentation model to enhance the global consistency of segmentation. In general, the optimization of the higher-order energy is extremely difficult. To make the problem tractable, we decompose the higher-order energy into two parts by utilizing auxiliary variables and then solve it by using an iterative process. We conduct quantitative and qualitative analyses on multiple datasets, and the proposed method achieves competitive results.

A study was conducted to improve satisfaction to school food service and to furnish source materials for nutrient education by researching degree of satisfaction of middle school students to school food service. Following results are from the study that targeted 215 male students and 173 female students in 5 middle schools in Daegu. Satisfaction rates regarding taste of foods, smell, proper temperature, use of seasonal food, cafeteria atmosphere, numbers of side dishes, and kindness of the cook in a cafeteria were higher than dissatisfaction. And dissatisfaction rates were higher in quantity and quality of foods, sanitation, purity of table wares, opening to nutrient education and related informations for students, opinion reflection of students, food serving time and gratification to food serving than the opposite. But the degree of general satisfaction on school food service were higher than the degree of general dissatisfaction. Sanitation was the first thing to be changed in school food service, then quantity of food and taste for the last. And there were notable differences between male students and female students in sanitation satisfaction. The variables that influence on satisfaction to school food service were sanitary administration, numbers of side dishes, quantity of foods, nutrient, smell and taste when ranked. And the main three things that have similar rate in quantity with satisfaction rate are taste, smell and nutrient of school food service. Through these followed results, degree of general satisfactions to school food service were higher than degree of general dissatisfactions. But sanitation, quantity and quality of foods, taste, and food serving size were not satisfactory for students in rate. Therefore it has to be improved to enhance satisfactions to middle school food service.
