The purpose of this study was to identify the concepts of body image, weight control and food behavior in 520 Korean high school seniors from Seoul and Gyeonggi Province. A questionnaire survey was conducted to investigate body image, concern of weight control, experience of weight control, the first time to try weight control, plan for weight control, reasons of weight control and food behaviors related with weight control. Anthropometric parameters such as weight and height were measured. Finally, data from 497 high school seniors were used for statistical analysis. The results were as follows. Many subjects had misperceptions. Among the subjects who perceived themselves as 'fat', 57.8% were normal weight and 0.5% underweight. Among the subjects who perceived themselves as 'thin', 59.5% were normal weight, 0.9% overweight and 0.9% obese. Girls were more concerned about weight control than boys (4.20 vs. 3.66). Weight loss had been experienced by 61.5% of the subjects and weight gain by 12.8%. First weight control was attempted by 71.3% of the subject at high school and by 28.7% at middle school. The majority of subjects planned for weight control before their freshman year. The boys choose 'health' as the primary reason for weight control, whereas the girls chose 'good appearance'. The total score of food behaviors varied significantly according to BMI. Overweight and obese subjects had more desirable food behaviors than normal weight and underweight subjects (24.00, 24.06 vs. 21.92, 21.52). However, total scores of food behaviors showed no variation according to sex, weight control attempt and body image. In conclusion, the high school seniors had misconceptions about body image and weight control. They were exposed to a high risk of inappropriate weight control and food behaviors. Therefore, proper nutritional education programs need to be developed for high school seniors to prevent nutrition problems related to weight control and to maintain desirable food behaviors.

The purpose of this study is to verify the difference in health and obesity according to water and coffee intake. The study subject is 900 female college students. Physical fitness factors measured in this study were physical strength(grip strength, back muscle strength), muscle endurance (sit-up), Flexibility(Sit & reach) and cardiopulmonary endurance(harvard step). The factors of body composition (intracellular fluid, extracellular fluid, protein, mineral, body water content, muscle mass, lean body mass, body fat mass) and obesity (BMI, body fat percentage, abdominal fat percentage, obesity) were measured with the Inbody equipment. SPSS program was used for all data analysis. Group differences were verified by two-way ANOVA and one-way ANOVA. The results are as follows. There was no interaction effect between water and coffee intake on health and obesity. Therefore, the difference of the dependent variables according to each independent variable was verified. There was no significant difference in physical fitness according to water intake and coffee intake, but there was a significant difference in body composition (intracellular fluid, protein, minerals, body water, muscle mass and lean body mass). Water drinking group more than 7 cups had significantly higher body composition than the 1-4 cups water drinking group. In the case of coffee, the body composition of the 3 cup intake group was significantly higher than that of the none intake group. Obesity was significantly higher than the none intake and 1-2 cup intake groups. Based on the study results, water intake was not related to obesity, but coffee was related. For further studies, it would be better to consider gender and age differences in drinking various beverages such as water and coffee and that would be used to suggest a desirable way of water intake according to individual characteristics of the better health.

Purpose: This study was conducted to assess the association of metabolic syndrome and its components with glaucoma. Methods: We investigated the associations of metabolic syndrome and its components (abdominal obesity, impaired fasting glucose, high blood pressure, and dyslipidemia) with glaucoma using data from 19,162 adults aged 40 or above among the Korean National Health and Nutrition Examination Survey III (2005), IV (2007-9), V (2010). The logistic regression analysis was used for assessing those associations after adjusting demographic, lifestyle, and social economic status and for assessing the association of metabolic medication intakes with glaucoma risks. Results: After adjusting for age and sex, the risk of glaucoma was significantly higher in the subjects with impaired fasting glucose(Odds Ratio (95% confidence interval): 1.78 (1.25, 2.53)) and metabolic syndrome (1.45 (1.01, 2.08)) than subjects without those. These associations increased when additional adjusting for smoking, alcohol use, regular physical activity, income, education status(impaired fasting glucose: 1.89 (1.29, 2.77), metabolic syndrome: 1.52 (1.03, 2.25)). Glaucoma prevalence was borderline significantly increased according to the number of metabolic abnormalities(age and sex adjusted p for trend = 0.055). Use of antihypertensive medication was significantly associated with the risk of glaucoma. Conclusions: Metabolic syndrome and impaired fasting glucose were significantly associated with the increased glaucoma risk. Use of antihypertensive medication was also significantly associated with the increased glaucoma risk.

This study examines the formation and change of relational trust among Korean adolescents using indigenous psychological perspective. Among adolescents, we examine the basis of trust of their parents, friends and teacher and also their trust in people and institutions. A total of 968 adolescents (227 elementary, 284 middle school, 213 high school, and 244 university students) completed a questionnaire that contains the Relational Trust Scale developed by Kim and Park (2004a), Generalized Trust Scale developed by Yamagishi (1998) and a scale measuring trust of people and institutions (Kim, Helgesen & Ahn, 2002). The results are as follows. First, adolescents trust their parents due to their sacrifice, followed by their counsel and advice, dependability, consanguinity and respects. They trust their teachers due to their counsel and advice, followed by respect, sacrifice, and mutual trust. They trust their friends due to their advice, followed by empathy, mutual trust, dependability, friendship and sacrifice. Second, trust of their parents are highest among the elementary school students and lowest for the middle school students and lower for older age groups. The trust in teachers are highest among the elementary school students and lowest among the middle school and university students. In contrast, trust in friends increase from elementary school students to older age groups. Third, among trust in people and institutions, they are highest for parents and family and lowest for politicians and political parties. Except for trust in friends, trust of significant others and institutions (family, teachers, neighbors, company executives and politicians) is highest among the youngest age group and it decreases with older age group. Fourth, Yamagishi's generalized trust was highest among the older age groups (high school and university students). The patterns of results for relational trust and generalized trust is different and it points to the importance of understanding trust from the indigenous psychological perspective.

Because of its restrictive harvest from spring to summer, It is necessary to preserve raw ascidians, Halocynthia roretzi, for the purpose of processing regardless of season. We evaluated low Temperature tolerance of ascidian and conditions for cold storage to secure the quality of the stock. To retard the browning of meat rapidly occurred after sucking, ascidians were blanched for 10 seconds in 10% boiling salt solution or dipped for 60 seconds in 0.2% $NaHSO_3$ solution, respectively. The samples were stored in ice, at $-17^{\circ}C$ or $-35^{\circ}C$ for 85 days, respectively. Changes in VBN, glycogen, brown pigment formation, total carotenoid, nucleotides and their related compounds during the storage were determined, and sensory evaluation of quality was also practiced. VBN and brown pigment formation were rapidly increased. Glycogen was gradually decreased and then not detectable after 85 days in case of ice storage. Lipophilic brown pigment was higher than hydrophilic and rapidly increased during storage. The result of sensory evaluation showed that the ascidian treated in 0.2% $NaHSO_3$ was good for 85 days of storage at $-35^{\circ}C$ . Judging from the results of chemical experiment and sensory evaluation, the quality of ascidian treated in 0.2% $NaHSO_3$ and stored at $-35^{\circ}C$ was better than that of other samples.

About 380 dental hygienists who were working in public health centers in 2004 joined this study with questionnaires about the evaluation of job training programs regarding oral health care. The findings are as follows. 1. As for the general characteristics of subjects including location, age and career, the dental hygienists in Public Health Subcenters outnumbered the dental hygienists in Public Health Centers, as the former accounted for 61.1 and the latter 35.3 percent. And the dental hygienists in their 36~40s made up the largest age group. The group in their 11~15 years career revealed 48.4, over 16 years career 35.7, under 10 years career group 15.9 percent, respectively. 2. The portion of certification in the respondents was 28.9 percent, as compared to the 71.1percent of non-certification. The major reasons of non-certification were not-applying(44.6%), participation rejected (29.3%). 3. Freqently requested curriculums were school based oral health program(4.42, the highest by Linkert 5 point scale), followed by oral health education(4.41), public oral health services for the toddler and for the elderly(4.04), for the disabled(3.92), oral health planning evaluation(3.85) and oral health survey& investigation(3.69). The gap between Dental hygienists at Public Health Center and Public Health Subcenter was statistically significant different(p < 0.001) in oral health survey& investigation and oral health planning evaluation.

Objectives: Presenteeism is known to be a much more economically damaging social cost than disease rest while going to work despite physical pain. Since COVID-19, social discussions on the sickness benefit have been taking place as a countermeasure against presenteeism, and in particular, farmers and fishermen do not have an institutional mechanism for livelihood support when a disease other than work occurs. This study attempted to examine the relationship between agricultural, fishing, and forestry workers and presenteeism using the 6th Korean Work Conditions Survey. Methods: From October 2020 to January 2021, data from the 6th working conditions survey conducted on 17 cities and provinces in Korea were used, and a total of 34,981 people were studied. Control variables were gender, age, self-health assessment, education level, night work, shift work, monthly income, occupation, working hours per week, and employment status. Results: As a result of the analysis, farmers and fishermen showed the characteristics of the self-employed and the elderly, and as a result of the regression analysis, when farmers and fishermen analyzed the relationship with presenteeism tendency compared to other industry workers, farmers and fishermen increased by 23% compared to other industry groups. Conclusion: This study is significant in that it has representation by utilizing the 6th working conditions survey and objectively suggests the need for a sickness benefit for farmers and fishermen who may be overlooked in the sickness benefit.

Consumers are very concerned about food safety as the risk with food increased. This study was conducted to evaluate the perceptions and practices of consumers on food safety in order to collect some information for the development of consumer education program. Total 500 consumers were asked to answer for survey constituted with 6 questions of generic information, 4 of food safety perceptions and 8 of food safety practices from June to July, 2006. More than half of respondents (51.8%) were unsatisfied with the food safety management of government while the individual practices on food safety were satisfactory. Especially, most respondents (98.7%) checked the expiration date of food when they purchased and 97% of respondents were washed hands before food preparation. The higher food safety perception, the better food safety practices of consumers. These results suggest that the systematic and continuous educations on food safety hazards and the principles of sanitation management are necessary for safe food handling and perception on food safety.

The articles, published in the Journal of Korean Forestry from Number 1(1962) to Number 6, Volume 91(2002), were surveyed and investigated for the research trend analysis about resource-plants for special use or purpose, i. e., edible plants, medicinal plants, feed resource, landscape plants, fiber plants, industrial usuage, and bee plants. If the purpose or subject matter of the research was construction or furniture timber production, mushrooms and/or pulp and paper, such research was not included in this study. These articles were classified again depending on the content of research into 14 categories: habitat environment, ecology, physiology, propagation, silviculture (tending and culture), genetics and breeding, identification, insect and disease control, animal-related research, component analysis, vegetation survey, biotechnology, management, and review. Among the total 1.434 articles published, 396 ones (27.6%) were related with plants for special use or purpose. Vegetation survey was 60 (15.2%): physiology 56(14.1%) : genetics and breeding 56(14.1%): propagation 53(13.4%): and ecology 37(9.3%). Siviculture research field included 11 articles (2.8%), which indicates that the management of resource-plants is so far from economic income as seen in the low number of management research filed articles, i. e., only 6 reports (1.5%) Korean white pine was most popular for research and included 42 articles: Robinia pseudoacacia 23: Castanea crenata 14: and ginkgo tree 14. Research related with these species had focused mainly on propagation, physiology, genetics and breeding, ecology and pest control. Based on this survey and analysis, the followings are suggested: 1. More research is required on forest herbaceous plants. 2. Cooperative research work with other industrial and/or scientific area is recommendable for commercialization including medicine, cosmetics, and food etc. 3. Research on resource-plant conservation, which includes biology, social education and policy, should be supported for next generation. 4. Mutual correspondence and information exchange about the research results between researchers and institutes is more necessary than now.
