Objectives: The purpose of this study was to investigate how clinical nutrition services is provided at a long term care hospital in Korea and to investigate job satisfaction levels of the clinical dietitians. Methods: Survey questionnaire was sent to dietitians working at a long term care hospital in Korea. The participating hospitals (n=240) were randomly selected from 1,180 long- term care hospitals using a stratified sampling method. A total of 134 long term care hospital s and 223 dietitians completed the survey of clinical nutrition service s and job satisfaction questionnaires The job satisfaction questionnaire included 27 job satisfaction questions on task, stability vision, working conditions, and relationship areas. Results: The average nutritional screening rate was 17.9% and the rate of computerized nutritional screening system was 9.7% in the participating hospitals. Nutritional intervention rate was only 3.2% of all patients. KOIHA (Korea Institute for Healthcare Accreditation) accreditated hospitals showed only 50% performance rate of nutrition service evaluation area. This shows that after achieving KOIHA accredition, many hospitals do not emphasize the performance of nutritional services. The job satisfaction scores in all four areas ranged from 2/5 to 3/5, implying generally low job satisfaction level in hospital dietitians. Linear regression analysis results showed that the "hospital adequacy grade" type was a significant predictor of job satisfaction level for two areas (working conditions & relationship). Conclusions: There is a need to provide proper standardized clinical nutrition services as a primary treatment and we observed large variations in the quality of nutritional service s in long term care hospitals. Therefore, government and local hospitals have to work on implementing nutritional programs and policies for improved service and care.

Objectives: This study was conducted to examine the status of foodservice management, with special interest on sanitary and nutritional food service in elderly day care centers. Methods: A total of 79 employees who managed foodservice facilities in elderly day care centers were included in the survey. The contents of the questionnaire consisted of general characteristics, importance and performance of sanitary and nutrition management, the reasons for poor performance, factors necessary for improvement, and the employee's demand for support. Data analysis was conducted using the SPSS v25.0. Results: Sanitary management showed an average importance score of 4.84 ± 0.40 and a performance score of 4.70 ± 0.61 (t-value: 8.260). The item with the lowest performance score was personal sanitary management (4.58 ± 0.71). In nutrition management, the average importance score was 4.52 ± 0.68, and the performance score was 4.20 ± 1.00 (t-value: 9.609). There were significant differences between the average score of importance and performance in both areas. As a result of an Importance-Performance Analysis, items that were recognized as important but had relatively low performance was "personal hygiene", "ventilation" and "food storage". Also in the nutritional management area, "menu planning for disease management" and "checking the saltiness in the soup" etc. had very low performance with low importance recognition. The items shown in the "low priority" quadrant were those that required professional management skills. In the areas that demanded support in foodservice management, education about sanitary and safe institutional food service had the highest score (4.42 ± 0.74), and all other items showed a demand of 4 points or more. Conclusions: Foodservice managers recognize the importance of foodservice facility management but performance is relatively low. Institutional support is, therefore, needed to improve performance. For items with low importance, it seems necessary to improve awareness of the necessity of these items and to provide education in this regard. To gradually improve foodservice management, continuous provision of education and training in these areas are of great importance.

Vibrio parahaemolyticus is recognized as one of the most important foodborne pathogens responsible for gastroenteritis in humans. The bla_CARB-17 gene is an intrinsic β-lactamase gene and a novel species-specific genetic marker of V. parahaemolyticus. In this study, a loop-mediated isothermal amplification (LAMP) assay combined with a lateral flow dipstick (LFD) was developed targeting this bla_CARB-17 gene. The specificity of LAMP-LFD was ascertained by detecting V. parahaemolyticus ATCC 17802 and seven other non-V. parahaemolyticus strains. Finally, the practicability of LAMP-LFD was confirmed by detection with V. parahaemolyticus-contaminated samples and natural food samples. The results showed that the optimized reaction parameters of LAMP are as follows: 2.4 mmol/l Mg²⁺, 0.96 mmol/l dNTPs, 4.8 U Bst DNA polymerase, and an 8:1 ratio of inner primer to outer primer, at 63℃ for 40 min. The optimized reaction time of the LFD assay is 60 min. Cross-reactivity analysis with the seven non-V. parahaemolyticus strains showed that LAMP-LFD was exclusively specific for V. parahaemolyticus. The detection limit of LAMP-LFD for V. parahaemolyticus genomic DNA was 2.1 × 10^-4 ng/μl, corresponding to 630 fg/reaction and displaying a sensitivity that is 100-fold higher than that of conventional PCR. LAMP-LFD in a spiking study revealed a detection limit of approximately 6 CFU/ml, which was similar with conventional PCR. The developed LAMP-LFD specifically identified the 10 V. parahaemolyticus isolates from 30 seafood samples, suggesting that this LAMP-LFD may be a suitable diagnostic method for detecting V. parahaemolyticus in aquatic foods.

The purpose of this study was to analyze task performance and importance level of the dietitian who is working in the public health nutrition area. Work oriented job analysis methodology was employed for the study purpose. Subjects of 38 dietitians currently working at health centers in 2002 were recruited. Based on the focus group interview with 7 public health nutritionists and 7 professors, information about task elements was collected. Questionnaires measuring work performance and self-perception of importance of the selected task elements were administered. The results of this study can be summarized as follows; 1) The tasks with high performance and importance level among 20 tasks are developing nutrition education material (B1), nutrition services for adults and the elderly (C3), writing the proposal for nutrition services (A2), evaluating service effect (A4), improving professionalism (E1), and self management (E2). 2) The task elements with high performance and importance level among weekly task elements are nutrition education for diabetes (C56), nutrition counseling for adults (C47), nutrition for hypertension (C53), managing and keeping records (C80), nutrition education for kindergarten and nursery school children (C42), searching for nutrition education materials (B26), and searching for media (B27). 3) The number of task elements with high performance and importance level among monthly task elements are 13 in the planning and evaluation of public health nutrition service, and 5 in developing nutrition education materials. The tasks of a dietitian in the public health center show a very wide spectrum. However dietitians recognize most of the tasks are important even though they cannot perform those tasks adequately.

This study evaluated the validity and reliability of applying a newly developed dish-based, semi-quantitative food frequency questionnaire (FFQ) for Korean diet and cancer research. The subjects in the present study were 288 Korean adults over 30 years of age who had completed two FFQs and four 3-day diet records (DRs) from May 2008 to February 2009. Student's t-tests, Chi-square tests, and Spearman's rank correlation coefficients were used to estimate and compare intakes from different dietary assessment tools. Agreement in quintiles was calculated to validate agreement between the results of the second FFQ (FFQ-2) conducted in February 2009 and the DRs. Median Spearman's correlation coefficients between the intake of nutrients and foods assessed by the FFQ-1 and FFQ-2 were 0.59 and 0.57, respectively, and the coefficients between the intake of nutrients and foods assessed by the FFQ-2 and the DRs were 0.31 and 0.29, respectively. The quintile classifications of same or adjacent quintile for intake of nutrients and foods were 64% and 65%, respectively. Misclassification into opposite quintiles occurred in less than 5% for all dietary factors. Thus this newly-developed, Korean dish-based FFQ demonstrated moderate correspondence with the four 3-day DRs. Its reliability and validity are comparable to those reported in other studies.

This study aimed to investigate the effect of the five senses activities involving food ingredients on the eating behavior of infants. The study was carried out four times over 6 months. We surveyed 65 nursery school infants and teachers who were registered at the 2020 Guro-gu Center for Children's Food Service Management in Seoul. They participated in the five senses education specialization project. The results of the study showed that the scores relating to unbalanced diet, hygiene management, dietary attitude, and dietary manners were visibly higher than those before participating in the five senses educational activities. In addition, there was a significant difference in the perception of the food ingredients used in the five senses education activities. Finally, as a result of investigating the types of education used before, during, and after the five senses education activities, and the need for education by type, cooking activities were observed to rank higher than other activities in all questions. Based on this, if dietary guidance is provided through a variety of five senses education activities over a long period rather than as a one-time event, it will be beneficial to the children's healthy eating habits.

인구의 고령화 및 건강에 대한 관심이 증가됨에 따라 유헬스케어 서비스는 발병 후 관리관점에서 발병 전의 예방 관점으로 그 목적이 점차 이동하고 있다. 그러나 기존의 유헬스케어 서비스는 원격진료 차원의 의료 서비스 성격이 강하여, 만성 성인병과 같은 대사 증후군을 예방 및 관리하기에는 한계가 있을 뿐만 아니라, 관리자 중심의 단방향 서비스를 제공함으로 인해 사용들이 중도에 이용을 포기하는 비율이 높았다. 이와 같은 문제를 해결하기 위하여, 본 연구에서는 사회 네트워크를 이용한 사용자 기반 유헬스케어 서비스 추천 시스템을 제안하였으며, 실세계에서 유헬스케어 서비스 추천 시스템의 활용 가능성을 제시하기 위하여 실제 의료원에서 대사 증후군 예방 및 관리를 위해 처방한 식단 및 운동 정보를 기반으로 유비쿼터스 컴퓨팅 환경에서 적용가능한 시스템을 구현하였다. 본 연구에서 제안한 시스템은 사용자가 선호하지 않는 서비스가 네트워크를 통해 확산될 가능성을 낮추는 동시에 추천의 신뢰성 제고를 위해 네이버들이 이용한 서비스를 공유함으로써 전체적인 추천 품질을 높인다. 즉, 사용자의 식습관 및 운동습관 등과 같은 생활습관을 개선하기 위하여 사회 네트워크를 활용함으로써 사용자간의 자율협업을 통한 개인화된 추천이 가능하다. 따라서 본 연구에서 제안하는 유헬스케어 서비스 추천 시스템은 생활습관 개선을 위하여 사용자에게 적합한 식단 및 운동을 제공하고, 생활습관의 개선을 통해 만성 성인병과 같은 대사증후군을 사전에 예방할 수 있을 것으로 기대된다.

Objectives: The study was performed to examine the dietary behaviors and life stress of middle school students in the Gyeonggi area. Methods: A total of 580 middle school students (295 males, 285 females) in the Gyeonggi area participated in the study between July and August in 2011. The study was a questionnaire-based survey that included dietary habits, dietary behaviors, and life stress. Results: For dietary habits, the score for drinking milk was higher in male students than in female students, whereas the score for eating fruits was higher in female students compared to male students. There were significant differences in foods eaten and preferred under stress between male and female students. Male students showed significantly less changes in the number of meals, amount of meal intake, number of snacks, snack intake, frequency of overeating, and appetite during stress than female students. Life stress score of students largely came from academic factors, and female students showed higher stress levels in personal and surrounding environment factors than male students. Life stress score was significantly lower in students with high and moderate levels of dietary habits than in students with a low level of dietary habits. Total score for dietary habits and scores for eating adequate amounts of foods for each meal, considering a combination of food groups at each meal and eating green and orange vegetables, were significantly negatively correlated with life stress score. Life stress score was significantly negatively correlated with meal regularity and positively with the level of overeating. Conclusions: This study may provide basic information on dietary habits and life stress according to gender and the relationship between dietary behaviors and life stress of middle school students, and it suggests gender-based nutrition education programs to solve undesirable dietary habits and dietary behaviors in students with higher stress.
