BACKGROUND/OBJECTIVES: This study aims to develop a mobile nutritional management program for integration into the already developed web-based program, Diabetes Mellitus Dietary Management Guide (DMDMG) for diabetic patients. Further, we aim to evaluate the amended DMDMG program. SUBJECTS/METHODS: The mobile application based on an Android operating system includes three parts: 1) record of diet intake, which allows users to take pictures of the meal and save to later add diet records into DMDMG; 2) an alarm system that rings at each meal time, which reminds users to input the data; 3) displays the diet record and the results of nutrient intake, which can be also viewed through the web program. All three parts are linked to the web-based program. A survey was conducted to evaluate the program in terms of nutrition knowledge, dietary attitude, eating behavior and diet intake by non-equivalent control group design among diabetic patients with 14 DMDMG users and 12 non-user controls after a one-month trial of DMDMG. RESULTS: Non-users did not use the program, but participated in the weekly off-line nutrition classes for one month. The program users showed increased healthful dietary behavior (P < 0.01) and dietary attitude scores (P < 0.05). More DMDMG users had higher nutrition knowledge scores after one-month trial than non-users. However, dietary intake significantly increased in non-user group for calcium and sodium (P < 0.05) while the user group did not show significant changes. CONCLUSIONS: The program has created positive changes in patients' dietary life. All the users were satisfied with the program, although some expressed minor difficulties with an unfamiliar mobile app.

Uncoupling protein-1 (UCP-1) plays a major role in thermogenesis, and has been implicated in the pathogenesis of obesity and metabolic disorders. The aim of this study was to estimate the effects of A-3826G polymorphism of UCP-1 gene on body fat distribution. Two hundred forty eight Korean female overweight subjects with BMI more than 25 kgfm2 participated in this study. The areas of abdominal subcutaneous and visceral fat of all subjects were measured from computed tomography cross sectional pictures of the umbilical region. Subcutaneous fat areas of upper and lower thigh were also measured. Body composition was measured by bio-impedance analysis, and serum concentrations of biochemical parameters, such as glucose, triglyceride, cholesterol etc, were also measured. Genotype of UCP-1 was analyzed by polymerase chain reaction (PCR) restriction fragment length polymorphism (RFLP) method. The frequencies of UCP-1 genotypes were AA type; $27.8\%,\;AG\;type;\;51.2\%\;and\;GG\;type;\;21.0\%,$ and the frequency of G allele was 0.47. Body weight, BMI, WHR, SBP, DBP and body compositions were not significantly different by UCP-1 genotype. Abdominal visceral fat area was significantly higher in AG and GG type compared with AA type (p=0.009), but subcutaneous fat areas were not significantly different by UCP-1 genotype. Among biochemical parameters, LDL cholesterol level was significantly higher in GG type compared with AA and AG types (p=0.033). Among all subjects, 121 subjects finished 1 month weight loss program containing hypocaloric diet and exercise. The reduction of body weight and BMI were lower in GG type compared with AA/AG type even though statistical significances were not found (p > 0.05). These results suggest that UCP-1 genotype has a significant effect on visceral fat accumulation among Korean female overweight subjects with BMI more than $25\;kg/m^2$.

Objective: Understanding consumer perception of meat quality in developing countries is an important issue since consumer perception of quality could be highly variable. In the current study, consumers' purchasing preferences affected by marbling and perception of quality were evaluated in a survey study. Furthermore, consumers' preferences for degree of doneness were investigated using both survey and consumer panel studies. Methods: The study was carried out in two phases. Firstly, a survey was conducted in Adana Province, Turkey to collect data related to the attributes affecting consumers' meat purchase decision and consumers' degree of doneness preferences. In the second phase, boneless ribeye was used to investigate consumers' degree of doneness preferences in a consumer panel. In addition, proximate analyses of the samples were conducted. Results: The survey study using pictures of marbling illustrations indicated that higher degrees of marbling might be considered too fatty to be purchased by consumers. Consumers' perceptions regarding the relationship between marbling and beef quality further indicated that marbling might not be acknowledged as a cue of a higher quality meat. Nevertheless, the results of the importance of some attributes related to intrinsic and extrinsic quality cues showed that consumers were looking for the cues that indicated not only quality but also safety of the meat during meat purchase. The results of both survey and consumer panel studies revealed that consumers might prefer higher degrees of doneness while consuming meat since a majority of the consumers' preference of degree of doneness was at least well done. Conclusion: This study revealed that consumer purchasing preferences might vary between countries regarding marbling and perception of quality. Furthermore, higher degrees of doneness could be the preference of these consumers. Thus, further studies are needed to increase consumer satisfaction in these countries.

This study was designed to assess the needs for nutrition education and educational materials for older adults. Two cross-sectional surreys were conducted. The first survey, conducted by personal interviews, was part of the large-scale elderly nutrition study. Subjects were adults aged 50 and over, recruited from 6 large cities and 8 middle-sized cities(n = 1,850). The second survey, done by mail survey using open-ended questions, was conducted with dietitians working at public health centers or hospitals(n = 53). Adults aged 50 and over were interested in topics such as healthly eating(32.1%), hypertension/stroke and diet(22.1%), osteoporosis and diet(11.4%), and diabetes and diet(9.2%). Television and radio(58.2%), health professionals(12.2%) and friends(7.9%) were common sources of nutrition information. Preferred topics of nutrition education and sources of nutrition information were different by general characteristics of subjects, suggesting that nutrition education or educational materials be planned considering the characteristics of subjects. About 70% of subjects indicated that they sometimes use or do not use nutrition information in daily lives, suggesting the need to provide more practical information. Among 53 facilities responding to the second survey, 73.6% provided nutrition education for older adults. Common topics for nutrition education included diabetes(39.3%), hypertension and stroke(19.1%) and general nutritional management(11.2％). These were consistent to the topics preferred by older adults. As materials In elderly education, dietitians wanted primarily to use leaflets and slides. Boards, booklets and posters were other commonly cited materials. For contents of elderly educational materials, dietitians mentioned the nutritional management for age-related diseases(33.8%), general nutritional management for older adults(25.4%) and practically applicable information(19.7%). They also suggested that nutrition education materials for the elderly should use larger print and attractive pictures, and be easily understood, as well as presenting simple, specific and practical information. These results provide baseline information for developing nutrition education and educational materials for older adults.

The objective of this study is to promote alternative plans on the prejudiced and distorted parts in school textbooks in the aspect of multi-functionality of agriculture and rural community. This was done through analysis of the contents in 44 kinds of schoolbooks in Korean language (30 of elementary school, 12 of middle school and 2 of high school). This will lead to promote the understanding about the multi-functionality and form the proper value system related to agriculture and rural community for children and juveniles using schoolbooks. A content analysis which is a research tool to classify all contents of materials containing the properties to become the object of interest in a systematic way, was employed to examine to what extent the contents on agriculture and rural community were reflected in the textbooks for elementary school, middle school and high school. The content analysis was done in two categories, namely; application method and function view. Application method had four types of texts, cases, figures pictures, and activities, while function view emphasized the relevance for the multi-functionality of agriculture and rural community (i.e., function of environment preservation, function of rural scenery and rural traditional culture conservation, function of maintenance and development of local society, and function of food security). The results of application method in elementary school showed that the textbook of the second-year class having a large amount of figures pictures related to agriculture and rural community, had the highest frequency in all six grades. In the function view, the environment preservation function was most abundant among a variety of multi-functionalities. In middle school, the average frequency had shown a rapid decrease. However, the function of environment preservation in the function view and the texts by application method were most frequent. in the first-year class. In high school, however, any mention related to agriculture and rural community was not made, in spite of the fact that the ten parts of textbook contained a lot of contents with a reasonable level. Based on the results of content analysis, findings and recommendations by part in textbooks for elementary school, middle school and high school have been drawn, and several examples for the content development to be included in the textbooks were listed.

Image analysis and k-mean clustering were conducted to develop a grading system of dried sea cucumber (SC) based on rehydration rate. The SC images were obtained by taking pictures in a box under controlled light conditions. The region of interest was extracted to depict the shape of the SC in a 2D graph, and those 2D shapes were rendered to build a 3D model. The results from the image analysis provided the morphological features of the SC, including length, width, surface area, and volume, to obtain the parameters of the k-mean clustering weight. The k-mean clustering classified the SC samples into three different grades. Each SC sample was rehydrated at $30^{\circ}C$ for 40 h. During rehydration, the flux of each grade was analyzed. Our study demonstrates that the mass transfer rate of SC increased as the surface area increased, and the grade of SC was classified based on rehydration rate. This study suggests that the optimal rehydration process for SC can be achieved by applying a suitable grading system.

This study was planned for an empirical review of foodservice operation in expressway rest areas for a menu strategy targeting staff and customers. The results were as follows. Main foodservice category included 10-30 items of Korean dishes. The needs for having branded foodservice menu in rest areas were high in fusion/fast foods, snack/ready-made and beverages. Employment of professional cooks in rest areas was low (10-30%), and the most important factor was 'taste' when cooking Korean foods. Foreigners preferred fusion/fast foods and snack/ready-made foods to Korean food, beverages and Japanese/Chinese foods, and most of the foreigners ordered food with 'no question'(55.5%) or 'some questions'(34.8%). Rest area staff prepared some photos/pictures of foods (80-100%) for menu comprehension, but the accuracy of menu transcription was very low. Customers used a rest area once or twice, stayed for 10-20 min(43.6%)/20-30 min(38.6%), visited by car(77.7%) to relax and use toilets(61.6%) on average. Favorite food and snacks were Korean(32.7%) and ready made/snacks(33.0%), and they spent 5,000-10,000 won(51.3%), 3,000-5,000 won(25.8%) on them. Customer satisfaction with rest areas was 'average' regardless of gender, age, education levels and jobs. With this analysis, we should prepare an efficient menu strategy for customer satisfaction and plans for analyzing problems along with alternatives.

This study was carried out to evaluate the usefulness and the effectiveness of the nutrition education website 'ifood(http://ifood.or.kr)', for children. A total of 262 children (5th and 6th graders) participated in the self-education program using the website which consisted of 4 sessions every two weeks. In each session, they were asked to answer some questions on the comprehensiveness of each topic while navigating the website. Nutrition knowledge (20 items), dietary attitudes (7 items), and dietary behaviors (10 items) were evaluated using questionnaires before and after the education. After the education, the usefulness and readability of the website was also evaluated. Most (97.2%) of the responders reported that the education using this website was helpful, 97.3% thought that the contents were reliable, 90.1% responded that the contents were easy to understand, and 88.8% answered that they would revisit 'ifood'. The menus they liked best were 'Interesting games' for 35.8%, 'How can I cook?' for 17.8%, 'How can I become slim' for 16.4%. This website might be more attractive by providing a 'greater variety of contents in detail', 'more music, motion pictures and images', 'more interesting games'. After the education, there was a significant increase in nutrition knowledge scores from 10.9 to 13.1. Although the total scores of dietary attitudes and dietary behaviors did not improve, there was a significant increase in each of some questions. These results showed that 'ifood', a nutritional education website, was desirable in reliability, aesthetics and enjoyability, and was effective in improving nutrition knowledge and some of dietary attitudes and behaviors in children.

The purpose of this study was to provide the proper nutritional management, and help to improve the health of girl students in a rural area. The nutritional survey, and blood sampling was conducted for five days, from April 26 to 30, 1983. The subjects of this survey were 110 students of girl's high school in Cheongyang area. The results were summerized as follows; 1) The daily food intake was 842.3g and that of animal foods was 34.4g. The average intake of calorie, protein, Ca, Fe, thiamin, riboflavin and niacin except Vit. A and Vit. C was below the RDA. Total calorie intake was l,802kcal. The ratio of carbohydrate, protein and fat was 81:11:8. 2) The extent of malnutrition was explained in terms of the amount of calorie, protein, Ca, Fe, and Vit. C. The predicted percentage of deficiency was 47.3% in calorie, 46.4% in protein, 61.8% in Ca, 48.2% in Fe, and 15.5% in Vit C of total subjects. 3) The mean values of Hgb, Hct and MCHC were 13.15g/dl, 39.57% and 33.2%, thus, the anemic prevalences were 10.9%, 2% and 78.2% respectively. The mean values of SI.TIBCand TS were $109.86{\mu}g$/61, $317.11{\mu}g/dl$ and 34.59%. 4) The correlation between the economic levels and nutrients intake was significant. Correlation between weight and nutrients intake was also significant but nutrients intake was not significantly correlated to blood contents.

This study aims to investigate the linguistic features of English signboards (ES) and socio-cultural aspects in Korea through university students' perspectives on the ES. The data comprised pictures and questionnaire on the ES from the students. The findings showed that ES reached to 55.4% for mainly the business of drink beverage and clothes. The text written by 'only English' included 2-3 words (43%), and that of 'combination of English and Korean' had 4-5 words (25%), which reached to 68% of the all. The 70% of ES were used for the business of drink beverage, food, and clothes, but these were not in harmony with the neighborhood, showing 42% of agreement. Good ES required 'visual factors (27%)', 'expression of business (23%)', 'elegant and luxurious style (19%)', and 'design and creativity (15%)', and these ES were the most in Shinchon areas. Overall, the present ES culture was insufficient to make harmonious atmosphere in Korea, which requires the support of policies and systems.
