Objectives: This study examined the salinity of soups provided at childcare centers by measuring the salinity for three years and providing basic data for sodium reduction. Methods: The soup salinity was measured using a Bluetooth salinity meter from January 2015 to December 2017 at 80 childcare foodservice establishments enrolled in the Suseong Center for Children's Foodservice Management in Daegu. Results: An analysis of the soup salinity each year showed that the salinity decreased significantly from 0.48% in 2015 to 0.41% in 2017, particularly in clear soups and soybean soups compared to other soups (P < 0.05). The salinity and sodium content in seafood soups (0.45% and 179.1 mg/100 g, respectively) were highest, followed by soybean soups (0.44%, 175.2 mg/100 g), with perilla seed soups containing the lowest (0.42%, 167.2 mg/100 g) (P < 0.05). The salinity was significantly higher in institutional foodservice establishments than small foodservice establishments (P < 0.001). The salinity and sodium content were the highest in foodservice establishments with a small number of measurements, and the salinity was the lowest in foodservice establishments with salinity measurements performed an average of 151 times each year (three times a week) or more (P < 0.05). The soup salinity was low in the order of winter, spring, summer, and autumn, and the salinity decreased significantly year by year in all seasons. (P < 0.05). Conclusions: The soup salinity was significantly lower in foodservice establishments where the salinity was measured more than three times a week, indicating that continuous salinity management is effective.

BACKGROUND/OBJECTIVES: The objective of this study was to compare dietary habits and mental health among middle school students in urban and rural areas based on bedtime, and to provide evidence supporting appropriate bedtime for Korean middle school students in relation to their healthy dietary habits and mental well-being. SUBJECTS/METHODS: The study population consisted of 25,681 second-year middle school students who participated in the Korea Youth Risk Behavior Survey in 2020-2022. Participants were asked about their bedtime and wake-up time during the past 7 days and were classified into five categories. The study compared the general characteristics, academic factors, dietary habits, and mental health of urban and rural students based on their bedtime. RESULTS: Bedtime was found to be later in the following order: urban female students, rural female students, urban male students, and rural male students. As bedtime got later, the rates of smoking and alcohol consumption increased. Students who went to bed before 11 p.m. had lower academic performance, while rural male students who went to bed after 2 a.m. had lower academic performance. Later bedtime was associated with increased smartphone usage, skipping breakfast, consuming fast food, and drinking carbonated beverages. Later bedtime was also associated with higher perceived stress levels, particularly among students who went to bed after 2 a.m., higher rates of suicidal ideation, experiencing sadness and despair, as well as the prevalence of clinically significant anxiety disorders. CONCLUSION: These results suggest that middle school students who go to bed too late have higher rates of smoking and alcohol drinking, as well as unhealthy eating habits, stress, suicidal ideation, sadness, and anxiety. Therefore, it is necessary to provide educational and social institutional support to promote adequate sleep for the health of adolescents.

The purposes of this study were 1) to analyze the effect of the ERP quality (system quality, information quality, service quality) on the performance (end user satisfaction, user's performance, system utilization) of business, 2) to conduct the causal-effect analysis between outcome variables (user's satisfaction, user's performance, system utilization) of ERP in the contract foodservice management company. The questionnaires were distributed to 260 end users (dietitians, foodservice management managers) in charge of managing the institutional foodservice such as the office (government agencies, factories), schools (universities, middle and high school) and hospitals which were managed by contract foodservice management company 'C' in Seoul and Kyunggi. The surveys were performed from July 26, 2004 to July 30. 2004. Two hundred and fifty (250) questionnaires were responded (response rate: 96.2%). The statistical analysis was conducted using SPSS Win (11.5). And the descriptive analysis, factor analysis, reliability test, pearson correlation, simple and multiple regression analysis were performed. The results showed that among the 3 factors (system quality, information quality, service quality), the system quality and information quality were proved to have an effect on the user's satisfaction and user's performance significantly (p < .05). The influence of ERP quality (system quality, information quality, service quality) on system utilization were testified to be statistically significant (p < .05). The user's performance were affected significantly by system utilization (p < 0.001) and end user's satisfaction (p < 0.001). As a conclusion, to improve user satisfaction, which is the ultimate performance variable of an ERP system, high quality of an ERP system is the pre-requisite. And the user satisfaction and performance of business would be higher with the better quality ERP system. When constructing ERP system for the contract foodservice management company, we should improve system utilization and user satisfaction altogether so that user's performance could be ultimately enhanced and we should make efforts to enhance the quality level of ERP.

The Recommended Dietary Allowances(RDAs, Nutrient standards), dietary guidelines, and food guides, each define aspects for a healthy diet in different ways. The RDA and food guide for Koreans were first established in 1962 by the Food and Nutrition Committee of the Korea FAO Association. The committee released the RDA and suggested ways to intake the recommended nutrients. Every five years, the committee has added more data and released revisions. The latest edition of the RDA is the 6th revision. In the beginning, the concept of basic food groups was emphasized as basic data for planning means based on RDA. In the 5th revision, the basic food groups and dietary guideline for public health from the Ministry of Health and Welfairs(December, 1990) suggests that, 1) Eat a variety of foods with a recommended fat intake equaling or less than 20% of total calories ; 2) Maintain ideal body weight and prevent obesity ; 3) Eat foods low in salt. Salt intake should not exceed 10g ; 4) Do not drink too much ; 5) Eat regularly and enjoy meals. After these guidelines were established, the first nutritonal education efforts guidelines were developed in 1984. Despite broad possibilities for application, they had limited use, mainly as a nutritional assessment and food balance sheet preparation. They were not well utilized in public nutritional education and nutritonal policy through the media because of the weakness of the government's food and nutriton policy. Also a lack of administrative support and dietitians in the health department and administrative organizations was partly to blame. In regard to public health and nutrition status, life expectancy has increased 10 years since the 70's and the elderly population increased threefold in 1995 compared to 1960. The common causes of death in 1996 by 19 Chapters classification, were first disease of the circulatory system ; the second, neoplasms ; the third, external causes fo mortality ; the forth, diseases of the digestive system ; and the fifth, respiratory system diseases, In food intake, grain and complex starch intake has decreased while fruit and animal foods have considerably increased. Therefore, energy from carbohydrates has decreased while energy from protein and fat has increased. Energy intakes from protein, fat and carbohydrates were respectively 12.5, 7.2 and 80.3% in 1969 but 16.1, 19.1 and 64.8% in 1995. 62.9% of the householes had the fat energy less than 20%, while 37.1% had the fat energy above 20%. The only intakes of vitamin A and calcium were below RDA levles. Therefore, nationwide attention should be focused on public nutriton education and public activities with supplementation of the RDAs, according to the food guide and the dietary guideline.

The purpose of this study was to investigate the sanitation affairs of general restaurants. The questionnaire survey on the attitude and knowledge toward sanitation, the attitude for sanitary administration and the sanitary education was conducted against new 600 restaurateurs who were educated from June 20 to July 11, 1996, at the administration hall's division of Kyungsangbook-do in charge of food industry that offered regular sanitary education to new restaurateurs annually. And the visit survey on sanitary practice was also conducted over 93 restaurateurs who obtained the commercial license for food service business. The findings from the survey were as follows; In regard to food sanitation, some 87.1 to 88.3% got the right knowledge about the reason and precaution of food poisoning, food's frozen or cold-storage, and the disposal of products after expiration of validity term. But it was about 20.8% to 50.0% who knew right about major precaution, storage temperature in refrigerator, fermented milk product's storage temperature and validity term. There was therefore a necessity for education in food sanitation. 38.2% of the subjects placed an emphasis on sanitary storage of foodstuffs as the most important thing in sanitary management. 33.8% emphasized cooking sanitation. The environmental sanitation was counted as the most important thing by 19.2%, and personal sanitation of worker was counted by 8.8%. There was differences in what they thought the most important thing was, according to the respondent's educational level and cooker. 86.6% replied it necessary to improve the sanitary level. The respondents who were younger or had better educational level emphasized more the need for it. Concerning health examination, 90.2% replied it necessary. 81.4% answered the reason was because there was a potentiality Quests might be infected with contagious disease. 78.5% pointed the need for sanitary education, but respondents with higher educational level less emphasized its needs. As the reason for poor sanitation, restaurateur's poor awareness about it was most frequently pointed out, by 46.9%. Cooking sanitation was most frequently counted, by 38.5%, as the first thing to be improved. As the most critical point in sanitary education, 34.5% indicated food's sanitary Quality control 30.9% mentioned sanitary treatment of kitchen facilities and peripheral environment, and 27.1% emphasized the summary of the general food sanitation. 77.7% answered to correct immediately in case of violating the Food Hygiene Law, and 12.0% replied to correct in the same case if they would get the order from public official or administrative action would be taken. Respondents with higher educational level answered more to correct immediately. What they wanted the government office to do toward sanitary improvement was a fund aid an facilities and management which was pointed out by 38.9%, a periodical sanitary education by 26.3% and a on-the-spot guidance of sanitary officials by 22.3%. In view of the food service business's sanitary practice, the rate of wearing a sanitary clothes was 32.9% in city and 35.0% in county. The rate of hand-washing without soap or non-washing at cooking was 73.9%, 85%, respectively. The rate of personnel sanitation was 34.2% in city and 50.0% in county. These things indicated the sanitation was not well practiced. To improve the poor sanitary conditions of the food service businesses, it is recommended to offer institutional backing and financial aid from administrative office, and encourage restaurateurs to take pride in their job. and conduct the sanitary education effectively by sanitary education institution.

The goal of this study is to determine, based on survey results, the underlying factors that affect the intention of the farmers who have not adopted the Hazard Analysis and Critical Control Points (HACCP) system for the rearing phase of pig production to adopt this system in the future. The research model for this study was con structed based on strategic contingency theory, the theory of the diffusion of innovation, and the technology acceptance model (TAM). Using structural equation modeling with partial least squares (PLS), this study analyzes the effects of the intensity of competition, the environmental uncertainty, the innovativeness and self-efficacy of the individual farmers, and the impact of the credibility of the Agricultural Technology Service Center (ATSC), which acts as the principal agent of technology dissemination and as a leader of change, on the perceived usefulness of technology and the farmers' intention to adopt the system. The results of the analysis are as follows. First, with regard to the underlying factors affecting the intention to adopt the new system, the intensity of competition within the industry and the institutional credibility of the ATSC were inferred to underlie the perceived usefulness. Second, institutional credibility has a positive impact on the perceived usefulness of the system, and the perceived usefulness, in turn, has a positive impact on the intention to adopt. The perceived ease of use also has a positive impact on the intention to adopt. Because the factor that has the biggest impact on the intention of a farm to adopt is the credibility of the ATSC, it is crucial for extension organizations, such as the ATSC, to make greater efforts to promote the expansion of the HACCP system. Because farmers feel that the implementation of the HACCP system is an instrumental strategy for coping with the high intensity of competition within the industry, they attempt to gain a competitive edge through the production of safe livestock products.

Autoclaving법으로 제조한 솔잎향미유(pine needle seasoning oil, PNSO) 0~3%(w/w)와 유화제를 2:1(w/w)로 혼합하여 식염수에 용해시킨 후 이를 밀가루와 반죽하여 건면을 제조하였다. PNSO 처리량이 증가할수록 수분흡수율, 부피팽창율, 고형분 용출율은 감소하였으며, 조리시간은 연장 되는 것으로 나타나 적정 처리량은 2~3%(w/w) 수준인 것으로 판명되었다. 한편, 관능검사 결과 PNSO의 처리에 따라 조리면에서 솔잎 고유의 녹색이 나타났으며, 조리면의 표면이 매끈하였고, 쫄깃쫄깃한 rheology 및 texture가 크게 개선되었다. PNSO 2%(w/w) 이상 처리군에서는 조리 후 20~30분이 경과하여도 조리면의 쫄깃쫄깃한 특성이 그대로 유지되어 식당, 단체급식소 등의 대량 취식용으로도 적합할 것으로 판단되었다.
