The purpose of this study is to examine the relationships among body composition, dietary intake, exercise, and life style in children(M=80, f=102) of the 5th and 6th grades of elementary school. Anthropometry and multifrequency bioelectrical impedance analysis were conducted to estimate body composition. Dietary intake, exercise, and life style were determined by using questionnaires. When obesity was classified greater than 120% of the ideal body weight, the prevalence rates of obesity were 31.2% for boy and 20.6% for girl. There were significant differences in body composition between nonobese(NO) and obese(OB) groups. Mean fat mass(FM) and lean body mass(LBM) were 8.6kg and 27.7kg for NO group and 16.7kg and 32.3kg for OB group, respectively. Also a significant difference was found in hydration rate(TBW/body weight)between groups( <0.01). No significant difference was found I total calorie intake and nutrient intakes between groups. No difference was found in the frequency and duration of outdoor exercise and indoor activities. Mean sleeping hours was 8-9hours for 62% of nonobese children and for 59% of obese children. However, calorie intake per body weight was significantly lower inobese children than in nonobese. The present study showed that significant differences existed in their body size and composition between NO and OB groups , while no differences existed in daily calorie intake, excercise , and life style. This may indicate that important obesity-promoting factors of early onset obesity may rely on other factors such as hereditary or environmental factors besides factors considered. Further studies are required to understand obesity-promoting factors in children. (Korean J Community Nutrition 2(5) : 680∼686, 1997)

Until Mandelbrot introduced the concept of fractal geometry and fractal dimension in early 1970s, it has been generally considered that the geometry of nature should be too complex and irregular to describe analytically or mathematically. Here fractal dimension indicates a non-integer number such as 0.5, 1.5, or 2.5 instead of only integers used in the traditional Euclidean geometry, i.e., 0 for point, 1 for line, 2 for area, and 3 for volume. Since his pioneering work on fractal geometry, the geometry of nature has been found fractal. Mandelbrot introduced the concept of fractal geometry. For example, fractal geometry has been found in mountains, coastlines, clouds, lightning, earthquakes, turbulence, trees and plants. Even human organs are found to be fractal. This suggests that the fractal geometry should be the law for Nature rather than the exception. Fractal geometry has a hierarchical structure consisting of the elements having the same shape, but the different sizes from the largest to the smallest. Thus, fractal geometry can be characterized by the similarity and hierarchical structure. A process requires driving energy to proceed. Otherwise, the process would stop. A hierarchical structure is considered ideal to generate such driving force. This explains why natural process or phenomena such as lightning, thunderstorm, earth quakes, and turbulence has fractal geometry. It would not be surprising to find that even the human organs such as the brain, the lung, and the circulatory system have fractal geometry. Until now, a normal frequency distribution (or Gaussian frequency distribution) has been commonly used to describe frequencies of an object. However, a log-normal frequency distribution has been most frequently found in natural phenomena and chemical processes such as corrosion and coagulation. It can be mathematically shown that if an object has a log-normal frequency distribution, it has fractal geometry. In other words, these two go hand in hand. Lastly, applying fractal principles is discussed, focusing on pulp and paper industry. The principles should be applicable to characterizing surface roughness, particle size distributions, and formation. They should be also applicable to wet-end chemistry for ideal mixing, felt and fabric design for papermaking process, dewatering, drying, creping, and post-converting such as laminating, embossing, and printing.

Spiritual direction is not a product created and developed by an individual, but a historical product that includes the church, believers, society, and the contexts of the times. Among the social changes related to spiritual direction, this study pays attention to monasticism and the Reformation. Focusing on these two social changes, this study analyzes the social dimension of spiritual direction indicated by the occurrence and change of spiritual direction and discusses its meaning. Around the time Christianity was officially recognized by the Roman Empire, monasticism began its long history, and Athanasius spread his ideal of monastic life and at the same time pursued the unity of the church and the monastic movement. Through this process, spiritual disciplines and educational models interacted and changed. During the Reformation period, Protestantism began to form new spiritual education and training. The Catholic Church pursued renewal through new concepts and practices of spiritual direction. Spiritual direction is being formed and recognized as a means of helping the spiritual life of individual Christians. The origin and change of spiritual direction mean that spiritual direction can be understood and applied differently reflecting the contexts and situations due to social interaction. Also, it should not be overlooked that spiritual direction can act as a cause of integration or division of the Korean Protestant churches.

This empirical research mainly investigates the relationship between work-family conflict and organizational performance. Three key variables apply for the empirical research; work-family conflict, organizational performance, and family-friendly HR practices. A total of 230 questionnaires is collected from mid-sized companies for hypothesis testing. The empirical analysis shows that work-life balance has a great importance on workers' job satisfaction and intention to leave. The family-friendly HR practices play a moderating role between work-family conflict and organizational performance. The findings support the fact that achieving work-life balance enhances organizational performance and using family-friendly HR practices is an ideal for balancing between work- and family life.

The purpose of this study was to be of use for the preparation of more desirable sex education system at elementary school, by making content analysis of the current textbooks related to sex education and surveying what opinions the persons concerned had about it. The purpose of this study were as follows; Elementary school textbooks were analyzed to find out what kind of sex education was included in them. And questionnaires on how to improve school sex education content were prepared, by which 207 male and female teachers were surveyed in the city of Paju and Koyang, Kyonggi province. The conclusions were as follows; 1. Content Analysis of Textbook Sex Education The content related to sex education was relatively much included in textbooks of the right life, morality and physical education. Although morality was a subject to be instructed for the third-grade students or older, elementary school students virtually received sex education from the first grade, as the right life and the joyful life were a subject for the lower-grade students, and this met the goal of sex education or the need of the times. However, sex education content leaned heavily toward family, family life or parental love. There was no mutual complement among subjects, and no link among grades, either. 2. Teacher Opinion on Sex Education Content for Each Grade When the subjects were asked about if sex education content was appropriate for each grade, they answered 20 items should be more emphasized and 6 items might be left out. And there were 6 items regarded by them as one that should be rearranged in consideration of grade. 3. The Ideal Opinion of Sex Education Content The following model could be recommended for elementary school sex education, which was designed to meet the objectives of school sex education as much as possible and to offer a systematic link among grades, based on the findings by textbook analysis and Questionnaire survey, and on elementary school sex education materials recommended by the Ministry of Education: The content selected for the first grade of elementary school was my body, cleanness of genitals, male-female cooperation, and family cooperation. For the second grade, the selected content was male-female physical difference, male female psychological difference, parental and I(origin of a birth). For the third grade, the selected things were important a body(cleanness of genitals), birth of a life, and male-female comprehension and cooperation. For the fourth grade, the selected things were physical development, management of genitals, physiology and management of menstruation, propagation and growth of organism, concern for the other sex, comprehension of and cooperation with the other sex, and prevention of sexual violence. Four the fifth grade, the selected things were secondary sex characteristic, physiology and management of menstruation, operation for phimosis, understanding of seminal emission, structure and function of the genital organs, birth and growth of a baby, television/sex information, and mass communications/sex information. For the sixth grade, the selected things were secondary sex characteristic, understanding of seminal emission, male-female cooperation, male and female role, male-female manners, mass communications/sex information, family and family life. Finally, what should be taught in sex education must be studied constantly, as it should be revised or supplemented periodically, according to student's sexual maturity or social, cultural changes.

The purpose of this study is about to consider the structure of dualistic recognition between "Gang-Ho"(ideal sanctuary) and real world in the "Songs of Fisherman" written by Lee Hyeon Bo. In order to do this job, I analized the arrangement of the contents and extract the exact in and outward meaning of elements and expressions; usage of them between lines of this Song. Based on these works, I tried to explain the confronted recognitions of the two worlds. At the first, about the arrangement and contents of this poem, It is consisted of 5 independent sub-poems and each of them are describing the value of fisherman's life(at the poem 가), separation from mundane world(나), satisfaction of fisherman's life(다), nature of "Gnag-Ho"(라), domiciliation in the place(마). It looks like that the writer intended to have the arrangement probability and likelihood connecting poems. Secondly, It contrast the nature of the "Gang-Ho" and real world. The sanctuary is a place of 'absence of worldly desire' and 'cordiality' that could afford one's harmonious life. On the other hand, the real world is a troublesome place which always conflicts political confrontations. For those reasons, the writer wants to satisfy with his living in "Gang-Ho" separating himself from the real world. Thirdly, The nature of "Gang-Ho" is 'absence of worldly desire' and 'cordiality' that one could be deserved his diligency becoming a part of the harmonious idealistic living place. Fourthly, on the character of story teller. Originally he is a incomer of "Gang-Ho" from real world. so that reason, he is showing dualism not to deny the loyalty oath to his king, while he intends to satisfy with the life in "Gang- Ho" separating himself from real world. As a gentry, at that time, the loyalty oath is inevitable one and that is found from writer's other works either. Fifthly, Characters of the different world recognition. The main reason of his intention to "Gang-Ho" roots on out of worldly confrontations, his separation from real world is on a joyous peaceful life just like in "Gang-Ho". this study believes the writer imply that 'absence of worldly desire' and 'cordiality' of "Gang-Ho", be a key role to resolve the confrontation of real world. Lee Hyeon Bo himself regards the two elements as a advisable attitude of life. At last, Seeing the writer's other work and literature's educational effect, this study defines that even if the poem outwardly express one's lyricism but inside it warns governors ruling attitude.

Objective: Due to rapid economic return, mixed crop-swine farming systems in Korea have become more intensive. Intensive farming practices often cause nutrient surpluses and lead to environmental pollution. Nutrient budgets can be used to evaluate the environmental impact and as a regulatory policy instrument for nutrient management. This study was conducted to select a nutrient budgeting approach applicable to the mixed crop-swine farms in Korea and suggest an effective manure treatment method to reduce on-farm nutrient production. Methods: In this study, we compared current and ideal gross nutrient balance (GNB) approaches of Organisation for Economic Co-operation and Development and soil system budget (SSB) approach with reference to on-farm manure treatment processes. Data obtained from farm census and published literature were used to develop the farm nutrient budgets. Results: The average nitrogen (N) and phosphorus (P) surpluses were approximately 11 times and over 7 times respectively higher in the GNB approaches than the SSB. After solid-liquid separation of manure, during liquid composting a change in aeration method from intermittent to continuous reduced the N and P loading about 50% and 47%, respectively. Although changing in solid composting method from turning only to turning+aeration improved the N removal efficiency by 30.5%, not much improvement in P removal efficiency was observed. Conclusion: Although the GNB approaches depict the impact of nutrients produced in the mixed crop-swine farms on the overall agricultural environment, the SSB approach shows the partitioning among different nutrient loss pathways and storage of nutrients within the soil system; thus, can help design sustainable nutrient management plans for the mixed cropswine farms. The study also suggests that continuous aeration for liquid composting and turning+aeration for solid composting can reduce nutrient loading to the soil.

This study aims to explore social participation needs among the elderly in Korea from the perspective of the elderly participant's. 40 Q-samples are drawn from the Q-population including attitudes and needs toward social participation in later life based on news articles, essays, research, documentary, and television shows. 35 subjects are analysed by the QUANL program and the types of social participation needs are divided into four patterns which accounted for 60.16% of the total variance. The elderly's portrayal of an ideal social participation is about making independent decisions and being able to actively participate in the activities they chose to do. However, their most undesirable scenario would be being confused and uncertain of what they should do the remainder of their lives. The needs of social participation among the elderly varies on four indicators such as ego, social capital, life satisfaction, life vitality and these four indicators have two sub-categories with a total of 8 types of classification. These 8 types differ by priorities, adaptation to life changes, motivation to social participation, and desired activity. Findings suggest that researchers and policy makers need to consider service user perspective on social participation in later life, not service provider perspective.

The study participants selected three participants in their late 40s and conducted a total of six sessions and in-depth interviews for 90 minutes to collect and analyze data using the phenomenological Giorgi research method. The conclusion according to the research results was drawn as follows. First, the shame, fear, reprimand, violence, passive attitude, and childhood that had to be adjusted seemed to maintain a stable life in the late forties, but still appeared in the present life. It was found that they showed a low self-satisfaction rather than positive satisfaction with self-concept and pursued an ideal self-image. Second, lifestyle was a time of severe depression, lethargy, and emptiness as a child, experiencing an unstable childhood due to a violent family, loss of attachment, overprotection, difficult economic conditions, and parental strife. It has been found that in the late forties, families have been established and religious life is being stabilized, and the responsibility for the family is valued. This shows how a lifestyle that gives meaning and recognizes what experience gives meaning to the childhood that one experienced. Insight into change and growth in middle-aged life, searching for and interpreting the initial recollections that they have experienced, accompanied by social and psychological changes in middle-aged men, discovering inappropriate meanings and goals and preparing for a second life in the age of 100 It is meaningful to provide.

A case-controlled, 12 week follow-up, study was designed to investigate the effect of dietician-delivered medical nutrition therapy (MNT) on the nutritional status and quality of life in hemodialysis patients. Subjects were recruited at Kyung-Hee Medical Center and were randomly assigned to two groups : the control and the MNT group. The MNT group received individualized MNT for 12 weeks. The results were as follows: 1) The mean ages of the control (n = 20) and MNT (n = 24) groups were 50.6 $\pm$ 14.8 and 45.7 $\pm$ 14.0 years, and the mean durations of dialysis were 2.3 $\pm$ 2.3 and 1.7 $\pm$ 1.9 years, respectively. The interdialysis weight gain of the subjects was higher than that recommended. 2) The indicators of the subjects nutritional status showed that S to 25% of the subjects had some degree of malnutrition, with most of them in the mild malnutrition category. 3) After 12 weeks of the experiment, the percentage of the ideal body weight (% IBW) of the control group decreased, but that of the MNT group increased. Changes in other anthropometric parameters in both groups during the study period were not significantly different. 4) At the beginning of the study, the 54% of the MNT group consumed more than 28 kcal/kg body weight/day and 50% consumed more than 1.0g protein/kg body weight/day. However, these percentages rose to 71% and 75%, respectively, after 12 weeks of the individualized MNT. 5) The serum albumin and blood urea nitrogen (BUN) levels of the control group decreased significantly artier 12 weeks of the experiment, while those of the MNT group did not change. 6) After 12 weeks of individualized MNT, the mean score of nutrition knowledge and total mean score of quality of life (QL) of the MNT group were significantly higher than that of th\ulcorner control group. Body pain and social functioning scores of the MNT group were significantly higher than those of the control group. The positive effect of individualized MNT on the hemodialysis patients consisted of their improved nutritional status, nutritional knowledge, and the quality of life. These results suggest that individualized MNT continuously performed by a dietitian can be helpful for hemodialysis patients. However, larger and longer term studies are needed to confirm these positive effects of MNT. In addition, the development of nutritional education programs for MNT is needed to increase the positive impact of MNT.
