  • The prevalence of obesity in children has steadily risen during recent years in developed countries. Child obesity has become a major concern to health providers since it has grown to epidemic proportions over the past few decades. This study was conducted to investigate the biochemical status, dietary habits and life styles according to the obesity degree among obese children residing in the Gyungbuk area. The subjects were 148 elementary school students (boy 103, girl 45) and classified as mildly obese (n = 56), moderately obese (n = 61) and severely obese (n = 31) by the obesity index. The average body weight and height increased significantly according to the obesity degree (p < 0.05, p < 0.001). Serum cholesterol concentration came under the normal level in all groups. Serum AST activity increased according to the obesity degree but it was not significant. Serum ALT activity increased according to the obesity degree (p < 0.05). Dietary habit score was lower significantly according to the obesity degree (p < 0.01). Life style of the subjects was significantly different for the level of 'healthy state (p < 0.05)', 'body perception (p < 0.01)', 'watching TV and video (p < 0.05)', 'normal sleeping hour (p < 0.05)' and 'degree of stress (p < 0.05)' according to the obesity degree. A positive relationship between obesity index and blood pressure, ALT has been shown in the subjects. Obesity index and dietary habit scores were negatively associated. Therefore, these results suggest that a practical nutrition-exercise education program for the prevention of child obesity should be provided to elementary school children.

  • Today, obesity is not recognized as a disease itself but is known to be the indirect cause of much chronic illness. Obesity has an impact on psychological disorders including severe inferiority, damage of body self-image, low self-esteem, personality disorders. The results in an increase of the mortality rate. Therefore, this study attempts to discover and evaluate stressful experience in obese teenagers. For this study, 21 girl students and 19 boy students in Pusan middle or high school located were selected. The data were collected from March to May at 1999. A tape-recorder was used under the permission of the subjects to prevent the loss of spoken information and communication. This study consisted of 563 reponses from girls and 461 responses from boys which were then classified with descriptive expressions and priority classifications. The results generated 72 common elements in girls and 54 common elements in boys. From these elements 24 syntheses of hypothetical definitions and 8 identifications of the structural definitions in both girls and boys were developed. The structural and hypothetical definitions were as follows: The analysis of the data was made through a phenomenological analytic method suggested by Van kamm, which is as follows: 1. Maladjustment to school life; lack of understanding of the teacher, insufficient exercise ability, and a feeling of burden in attending the school obesity program. 2. Conflict in family relationships; lack of understanding from the family, a feeling of alienation. 3. Conflict in friend relationships; lack of understanding among friends, constant comparisons in appearance and body with friends (in girls) and estrangement from friends (in boys). 4. Conflict in acquaintance of the opposite sex; hoping to meet the opposite sex, lack of understanding of boy friends (in girls), feelings of pain, feelings of anxiety (in girls) feelings of burden (in girls) feelings of envy (in boys). 5. Negative body image: shape of body; feelings of pain; feelings of powerlessness; feelings of discomfort, and reception; emotional disorders (in boys), and change of personality (in boys). 6. Health disorder: Physical and psychological discomfort. 7. Feelings of burden in weight control; negative experiences in weight control, interference with family and friends, the difficulty in diet therapy, feelings of burden in exercise (in girls), to be teased by the public through mass media (in boys).

  • Objectives : The aims of this report are to examine the personal characteristics and to determine the different reactions against stress by constitutions. To achieve these goals, the statistical research was adopted. Methods : First of all, the total numbers of 398 middle school students were classified into three constitutions by QSCC II. According to each type of constitutions, both of the KPI Personality Test and Multidimensional Encountering Scale (MES) on how to deal with stress were conducted. Summary of the findings : 1. Based on the findings assessed by the QSCC II test, the constitutional distribution reveals the difference according to genders. In Chi-square test, the girl reveals significantly high (p<0.05) distribution in Soyangin. 2. In Independent T-test regarding KPI personality, the girl reveals high significance (p<0.05) in terms of 'Sociability', 'Responsibility', 'Synchronism' and 'Self-feminity' (or Feminization) while the boy reveals high significance in 'Goal-driven' (p<0.05). 3. In Independent T-test regarding the multidimensional encounter scaling, the girl reveals high significance (p<0.05) in D (expression of emotion). 4. In case of the boy, the Soeumin shows low significance (p<0.05) in 'Leadership' and 'Sociability' compared to the Taeumin or the Soyangin. On the other hand, the Soeumin reveals high significance (p<0.05) in 'Responsibility' and 'Self-control' compared to the Soyangin and additionally, shows high significance (p<0.05) in 'Self-feminity' (or Feminization) compared to the Taeumin or the Soyangin. Furthermore, the Soyangin shows high significance (p<0.05) in 'Self-confidence' compared to the Soeumin or the Taeumin. 5. In case of the girl, the Soyangin reveals high significance in 'Sociability' and 'Self-confidence' compared to the Soeumin or the Taeumin while the Soeumin has high significance in 'Synchronism' compared to the Taeumin or Soyangin. On the other hand, the Soeumin has high significance in terms of 'Responsibility', 'Self-control', and 'Self-feminity' (or Feminization) while showing low significance in 'Flexibility' compared to the Soyangin. 6. For boys, the Soeumin has low significance in 'Sociability' in comparison with both the Soyangin and the Taeumin, whereas for girls, the Soyangin reveals high significance in 'Sociability' in comparison with both the Soeumin and the Taeumin. As per the 'Self-confidence' and 'Responsibility', it has been proved that there is no notable difference between the boy and the girl, but to the contrary, as per the 'Self-confidence', both for the girl and the boy, the Soyangin has high significance (p<0.05) in comparison with the Soeumin and the Taeumin. In addition, in 'Responsibility' side, it is recognized that the Soeumin shows high significance (p<0.05) in comparison with the Soyangin both for boys and girls. Only the difference between genders, as to the 'Self-confidence', is that the Soeumin shows low distribution compared to the Taeumin in the case of boys, while the Taeumin shows low distribution compared to the Soeumin in the case of girls. In 'Self-feminity' (or Feminization), for boys the Soeumin shows high significance in comparison with both the Soeumin and the Taeumin, but to the contrary, for girls the Soeumin shows high significance (p<0.05) only against the Soyangin. 7. In case of boys, as to 'Conformability (compromise)', the Taeumin compared to the Soeumin reveals high significance (p<0.05), while for girls, the Soeumin compared to the Soyangin or the Taeumin reveals high significance (p<0.05). Consequently, it presents that the Soyangin has a tendency not to confirm (compromise) relatively in comparison with other constitutions regardless of the genders. Conclusions : In general, except that it shows some constitutional deviation by genders, the statistical findings of this report agree and comply with the personal characteristics of Sasangin presented by Je-Ma Lee.

  • Under the full consideration of the growing need and importance of population education in the field of home economics in Korea, the study was carried out to verify and assess the following facts on the current issues of population education of home economists who are presently engaging in teaching professions as the teachers of middle and high school and professors of college and universities by setting its primary objectives of the study as followings; 1) to assess the degree of general knowledge and attitudes of home economists toward population education in the field of home economics, 2) to verify the problems encountered in implementing population education by home economists in its field, 3) to find an existing status of previous trainings received and other activities of population education of home economists aimed at utilizing these findings as a part of reference materials when the population education is conducted in the field of home economics. In order to attain these objectives described above, the questionnaire was carefully designed to house a total of 40 questions with good combination of multiple-choice and the simple answer questions. The mail questionnaire survey was conducted by establishing teachers of home economics at middle/high schools and college/universities as Senior Home Economists(SHE) who are from public, private liberal arts and vocational schools. The rate of response observed during the survey was 45.6 percent and the findings of the survey research are as follows: 1) Examining the status of the respondents by residence and religion, it was found that 45 percent of middle & high school teachers ar.d 59. 1 percent of college professors are residing in Seoul city area and that the largest percent of them are christian in their religion. Analyzing respondents by their ages, 56 percent of middle/high school teachers are in their 30s, 45 percent of college professors are in their 40s, and 37 percent of college teachers are in their 30s. In addition, 13 percent of the total respondents are found to be unmarried. The study also revealed that 71 percent of the college professors finished Master Degree course and 82 percent of middle/high school teachers are graduated from college level lasting 4 years. Looking over the status cf major fields of respondents, 68.4 percent of middle/high school teachers are specialized in home economic education and the college professors, on the other hand, show relatively even prortion by specializing in the order of food & nutrition science, clothes & textile science and home managerial science. As far as the length of teaching experience is concerned, a relatively longer period of teaching experience is observed in the college professors in comparison with that of middle/high school teachers. In other words, 33.3 percent of middle/high school teachers are experienced in teaching from 6 to 10 years on average while 43.9 percent of college professors show more than 16 years of experience. 2) Examining the status of existing number of children cf the respondents, one boy and one daughter pattern is predominant, showing 28.5 percent in middle/high school teachers and 21.1 percent in college professors. As for the desired number of children of unmarried respondents, it is observed that 43.8 percent of middle/high school teachers desire to have one boy and one girl, and 31.3 percent of college professors want to have one child regardless of the sex. By assessing the degree of awareness of the population education through their students, it is observed that 53 percent of middle/high school teachers and 50 percent of college professors are aware of population education in some extent and that a majority of respondents took the positive attitudes toward an inclusion of family planning components into the formal school education. Another noteworthy to observe is that a total of 84.8 percent out of middle/high school teachers pointed that the population education currently conducted at schools as a part of home economics are less sufficient than it should be. 3) Analyzing the tendency as to whether the respondents were experienced in receiving population education during the time when they were students, 75 percent of college professors and 59 percent of middle/high school teachers responded negative answers in the survey. In the mean time, a total of 50 percent of the respondents replied that they began to acknowledge the importance of population education mainly through the participation of some sort of population-education orientend seminars, experienced by 40 percent of college professors and 80 percent of middle/high school teachers. 4) What it calls attention in this study was to find that 96.5 percent of middle/high school teachers and 72 percent of college professors conduct population education to some extent during their lecture hours and that more than 80 percent of them are never experienced in teaching population and family planning contents in their regular classes. It is, on the other hand, found that no more than once was the response of those who believe themselves that they are experienced in teaching these relevant components to their students. Analyzing the contents of the subjects being taught in the class, a large percent of them are found to be consisted of population and family planning contents. According to this study, the current population education through the formal school is quite inactive. Analyzing the facts, 44.9 percent of the college professors responded that the population and family planning components are quite apart from their specialization which eventually generates lack of interest in the field. 5) It is also noticed through the study that the degree of frequency of commenting on population and family planning contents during the classes was depending significantly on their specializations which means that the degree of frequency varies from a major to another. Those who majored in home managerial science was the first one, as compared to others who majored in different specializations. Glancing over the status of correlations between ages of the respondents and numbers of seminar paticipation, it is quite clear that the aged group participated more than the younger group did, and that the most highest number of participations made by college professors were those who are in 50s. In addition, it is also found that those who are aged 20s and 60s of the respondents were the group who comments least on the contents of population and family planning at their classes. The suggestions and recommendation made through this survey research are as follows. 1) No one denies that the rapid increase of population, as compared to the limited size of land and resources, will certainly affect adversly to an enhancement of individual life quality which will, eventually, bring forth the poverty of the nation. This is the reasson why we are insisting that the world population be controlled up to an optimum level with a matter of global concerns. It is our understading that the primary aim for reducing number of population is believed to be attained only by conducting the systematic and comprehensive population education through the formal schools. Therefore, the role of home economists in the field of population/family planning education is considered very importment due to the fact that an ultimate goal of population education is placed in elevating the quality of family life by having optimum number of children through family planning program. 2) It is quite clear that home economists as teachers of formal school in all level are invited to pay their attention on redefining the ultimate goal of education and that of population education. We also understant that the primary objective of population education is to change the norm and value of the clients by replenishing the students with pertinent knowledge and attitudes on population and its related problems through a sort of education in order to attain the ultimate goal for enhancing the quality of life. There is no exception in the theory of home economics. An altimate goal of home economics is to elevate the general quality of life through an establishment of value existed in daily life. Considering the relations between population education and home economics, it is quite indespensable to bandle population components as an integral part in the field of home economics. We believe, therefore, that the senior home economists positive participation in the effort population control is more needed than it has been. 3) It is also strongly urged that population education should be a part of instructor training course for home economics. In other words, the teacher of home economics should be well aware of population and its problems by teaching interrelationship between population education and home economics, needs, contents and methods of population education during the instructor training courese for home economics. In addition, the senior home economists should be encouraged through positive participation on the short term training by types of domestic and international seminar, workshop, etc. 4) We certainly believe that the population education can not sustain itself without any backing-up of information and findings' of various and comprehensive researches of natural and social sciences. Accordingly, every senior home economist is invited to exert their maximum effort to conduct systematic study with an aim to utilize these findings and information at best in population education in the field of home economics. Therefore, we consider that the development of training material is imminent in order to provide effective and efficient population education through the for training of home economies. It should be noted that these training materials must be carefully designed, tailored and developed to meet the different classes of trainees under the considerations as to whether it is easily adaptable and infusable into the curricula of every field of home economics, and it is acceptable in the degree of difficulty and quality in its contents. 5) It is true that there are many domestic and international research rapers, reports and findings in the field of population education and family planning. However, there is a tendency that the most of research papers are heavily relying on the authors intension and preferences in its expression and publication. Under these circumstances, it is urged that the home economists should aware of the growing need of the technical training in order to keep these available information and research findings reprocessed and redesigned to insure the practical application into the population education in the field of home economics in Korea.

  • This study was carried out to find the relationship between the eating disorder associated with BMI(body mass index) and nutrition knowledge by surveying 476 middle school girl students in Won Ju, Gang-Won Province, South Korea. BMI is a standard suggested for oriental people and it was differentiated into the underweight, the normal weight and the overweight. To determine the eating disorder, EAT-26(Eating Attitude Test-26) was used and in order to find out the level of nutrition knowledge DGE (Deutsche Gesellschaft fur Ernahrung) was used after some modifications and supplementations. And the results are as follows; 1) Out of the students surveyed, 22% are in underweight group, 64% are in normal weight group and just 12% are in overweight group. Except the students in underweight group, most of the surveyed students wish to lower the weight below normal weight. 2) Relationship was found between BMI and EAT-26 score that is related with eating disorder behavior, Total score was higher in overweight group than in underweight and normal weight group (P<0.001). When the score for individual question about eating disorder is considered in detail, the score for the questions preoccupied with the weight reduction was higher in overweight group than in underweight and normal weight group(P<0.001). For the questions about bulimia there was no difference according to BMI, however, for the questions about restraining food intake the score was high in overweight group(P<0.001). 3) The score of nutrition knowledge in line with BMI was different. It was found that the total score and the score for the questions about fat, calorie requirement, and calorie content in food were different. The total score showed the highest in overweight group in comparison with the ones in underweight and normal weight group. (P<0.05). Out of maccronutrient like carbohydrate, fat and protein, only the fat showed significant difference according to BMI and it was lower in overweight group than in underweight and normal weight group.(P<0.05) Out of the questions about calorie requirement, significant difference was found in the score for the questions about calorie requirement and calorie content in food. It was lower in overweight group than in underweight and normal weight group (p<0.05).
