  • For the purpose of developing ‘Web-Based Nutritional Education Program’, this study did instructional analysis, analysis of entry behaviors and learner characteristics to select instructional contents for nutritional education program for junior/senior high school students. Survey questionnaires were distributed from October 21, 2002 to October 26, 2002 to a total of 564 junior/senior high school students in Seoul. The total number of questionnaires collected and used in our study was 479, which is 84.9% of the total questionnaires distributed. As a result of the curriculum analysis of ‘Technology-Home economics’, subjects related with ‘food and nutrition’ in the 7$^{th}$ educational course study result, lessons including the contents of food and nutrition were ‘nutrition and meal of adolescent’ in 7th grade, ‘family meal management’ in 9th grade and ‘practice of home life’ in 10th grade. According to the curriculum analysis, ‘nutrition’ and ‘food’ were chosen for the superior subjects of nutrition education program and four subordinate subjects per superior one were developed. Then, entry behaviors and learner characteristics were analyzed: life characteristics, internet usage, anthropometrics data and nutritional knowledge. Students were interested in using computer and preferred passive activity to dynamic activity. According. to the analysis of internet usage, WBI for students should composed active parts such as game, moving image, immediate reply and follow-up bye-mail, bulletin board and com- munity activity. Students’ BMI were in normal range but they were lacked nutritional knowledge. We wrote performance objectives that were specific behavior skills to be learned, the conditions under which they must be performed and the criteria for successful performance. The next step for developing the WBI nutrition education program would be based on the results mentioned above.

  • Among animals, the rabbit is known to be affected most sensitively by dietary changes and to be most susceptible to atherosclerosis. The exact reason is still unknown as to whether the primary cause is intrinsic (tissue itself) or extrinsic such as a blood factor which could be influenced by various dietary means. It is of utmost importance to check the nutritional quality of rabbit meat before it is accepted and adapted as a daily food item. To evaluate nutritional quality of rabbit meat, studies on various aspects of lipid components were carried out in comparison with other animal meats such as beef, pork and chicken also included in the study was the question whether the cooking and storage conditions influence the composition of fatty acids and cholesterol level. Some results and findings are listed below: 1. The content of linoleic acid (18 : 2), one of the essential fatty acids, was much higher in rabbit meat compared to the other meats. The Percentages of this Polyunsaturated fatty acids, was much higher in rabbit meat compared to the other meats. The percentages of this polyunsaturated fatty acid in terms of total fatty acids were $37.3{\pm}3.7$, 5.9, 14.5, and 21.9% for rabbit, beef, pork, and chicken respectively. The degree of unsaturation was high not only in meat but also in liver and adipose tissue of rabbit. The values of iodine number, the indication of degree of unsaturation, were known to be $102{\sim}107$, $32{\sim}47$, $46{\sim}67$, and $55{\sim}77$ for rabbit, beef, pork, and chicken respectively. Such a high proportion of this polyunsaturated fatty acid contained in rabbit meat could be harmful due to their Peroxidation effect. 2. A small amount of lower (short chain) fatty acids was isolated from rabbit tussues, which were not observed in other animal's tissues. The significance of this small amount of short chain fatty acids contained in rabbit meat remained an open question. 3. The concentration of total cholesterol in rabbit meat was similar to that of otherr but the content of esterified cholesterol was higher in rabbit meat. This was probably due to the perference of cholesterol to esterify with unsaturated fatty acids. By roasting the percentage of Polyunsaturated fatty acids was decreased while saturated palmitic acid was proportionally increased. 4 The composition of fatty acids were affected more by dry heat than moist heat. More research should be pursued to improve methods of preservation and storage to prevent possible peroxidation and rancidity problems of rabbit meat. In the meantime, the public should be informed to eat fresh rabbit meat and not to store it for a long period of time. This study was supported by the Ministry of Science and Technology in Korea.

  • The U.S. response to increased international competition was examined in the present study in order to have more comprehensive understanding of the U.S. textile and clothing market. The method employed to conduct the study was the analysis of the written materials, interview with professionals, and the survey of the actual situations of the U.S. textile and apparel industries. The results are summarized as follows; 1. Official U.S. textile and apparel trade policy has been quite has been quite protective since 1950's. The protective trend has been embodied in Japan Cotton Textile Export Control (reciprocal trade agreement signed by the U.S. and Japan in 1957), Short Term Arrangement Regarding International Trade in Cotton Textiles, Long Term Cotton Textile Arrangement (1962∼1973), and Multi-fiber Arrangement (1974∼). Other governmental programs designed to improve the competitiveness of the U.S. textile and apparel industries include Long-term Textile and Apparel Products Export-expansion Program, and 807 Trade to take labor cost advantage. 2. Along with the quite protective governmental trade policy, the corporate responses have been made such as new sourcing mixes, investment in technology, specialization in the textile and apparel industries, and recent strategies pursued by retailer's. The apparel industry was subject to pressure from imports that increased at moderate levels, and the U.S. textile and apparel industries have made extensive efforts to adjust to the increasing competition from abroad. The textile and apparel industries have taken steps to increase labor productivity through automation, to speed management to create and introduce new products and new methods, and have lowered indirect overhead costs. Several industrywide promotion campaigns have attempted to establish a greater public awareness of international competition and to develop a preference for apparel produced in the United States. 3. Regarding these response of the U.S. and other situations of world textile and apparel trade market, much of the sense of crisis that pervades Korean textile and apparel industries has to do with the problem of adjusting government and corporate policy. Textile and apparel industry of Korea faces on going pressure to reduce costs, improve quality, increase service, develop new markets, diversify, and differentiate itself from its foreign competitors. The strategies that have been adopted in the past have generally worked in the past, but the time has come to adopt strategies that reflect present conditions. If this is not done, then we stand to lose large segments of these industries, which once lost will not easily be regenerated.

  • The purpose of this study was to estimate the consumption prevalence of vitamin and mineral supplements as health functional foods (VM-HFF) and to examine the factors associated with VM-HFF consumption behaviors in adolescents. A total of 1,407 adolescents attending middle or high schools from various cities and rural communities in Korea participated in this study. The prevalence of VM-HFF consumption was 41.7%, with boys showing a higher consumption than girls (p<0.01). VM-HFF consumption was higher in families with higher socioeconomic status and for families with parents that exhibited higher concerns about their child's health, growth, and nutritional intake (p<0.001). Most consumers of VM-HFF consumed HFFs 'when healthy' (50.1%), and acquired nutritional information from 'their families & relatives' (50.9%). Most consumers responded that VM-HFF was 'a little effective' (54.3%), followed by 'no obvious effects' (37.1%), and 'very effective' (7.4%). The effectiveness of consuming VM-HFF was mainly for 'fatigue recovery' (39.0%) and 'health improvement' (28.2%). Most consumers purchased HFFs at 'pharmacies & oriental medicine clinics' (53.8%) and at 'health functional food stores' (18.8%). Most consumers 'occasionally' (51.1%) or 'seldom' (27.3%) checked nutrition facts when purchasing, with 58.9% of consumers understanding the nutritional label for 'the most part', but only 8.7% of them understanding it 'very well'. Among the VM-HFF, consumers preferred calcium- and vitamin C-supplements. Consumers' mini-dietary assessment scores were higher than those of non-consumers. The results above showed that VM-HFF consumption was widely spread among adolescents, but few consumers checked and understood the nutrition label when they purchased VM-HFF, and were highly dependent on the advice and information from non-professional nutritionists, such as families & relatives. Therefore, it is necessary to educate adolescents to help them read nutrition labels and select the proper VM-HFF.

  • The purpose of this study was to estimate usage of vitamin and mineral supplements as over-the-counter (VM-OTC) drugs as well as examine factors associated with VM-OTC usage in Korean adolescents. A total of 1,407 adolescents attending middle or high school in all parts of country were included in the analysis. Prevalence of VM-OTC usage was 56.1%, and it was higher as monthly income, father's education level, and socioeconomic status of family increased (p<0.001). VM-OTC intake was higher in middle school students than in high school students as well as in rural areas or small & mediumsized city residents than big city residents (p<0.01). Subjects mainly received information on VM-OTC mainly from 'family and relatives' (46.6%), whereas only 20.3% received information from experts. Subjects took VM-OTC 'when they are healthy' (49.1%), 'when they feel sick' (17.7%), 'when they are on a diet' (17.3%), and 'when they are stressful' (15.9%). The effectiveness of taking VM-OTC were mainly 'fatigue recovery' (35.0%), 'health improvement' (30.6%), and 'nutritional status improvement' (13.2%). The most frequently used VM-OTC was vitamin C (49.1%), multi-vitamins (18.6%), multi vitamins & minerals (13.2%), and calcium (9.2%). Among VM-OTC users, only 21.9% replied that they usually check the nutrition facts when they buy products, 62.4% follow the recommended dosage, and 9.7% fully understand the nutrition labels of the products. According to logistic regression analysis, the most influential factor affecting VM-OTC use was parents' and siblings' VM-OTC consumption (p<0.001). In addition, school type (middle or high school) (p<0.01), residence (p<0.05), self-concerns about health (p<0.05), father's education level (p<0.05), and socioeconomic status of family (p<0.05) all influenced VM-OTC use. These results show that VM-OTC use is widespread among adolescents, few users actually check and fully understand the nutrition labels when they purchase VM-OTC, and they are highly dependent on unprofessional advice and information. Therefore, it is necessary to educate adolescents to help them select proper VM-OTC and read nutrition labels.
