Management of nutrient intakes through behavior-mordification can be important for improving exercise performance in athletes. The purpose of this study was to determine the effectiveness of nutritional counseling for improving exercise performance capability in athletes. The subjects were seven golfers and fourteen ju-do athletes from Hoseo university, and they have nor received professional hel[ from dieticians. Prior to nutritional counseling, their dietary intakes, lifestyles and dietary habits were evaluated. Nutritional counseling sessions were conducted by a trained dietician every 2-3 weeks for 3-4 month. After 5 counseling sessions, nutrient intakes, lifestyle and dietary habits were re-evaluated. Exercise performance capability was measured by maximal exercise stress test using treadmills. Individual data were assessed as quality index represents the better nutritional status. The common dietary and lifestyle problems were overeating binging, overeating, snacking and drinking alcohol prior to the nutritional counseling. After counseling sessions, the quality index of dietary habits seemed to decrease, especially in ju-do athletes, representing nutritional problems were resolved. Body fat and body mass index decreased in ju-do athletes, but not in golfers. Both athletes have shown to increase oxygen uptake at anaerobic threshold and maximal oxygen uptake status, which represents that the athletic performance capacity was improved after counseling sessions. Their respiratory quotients were decreased. In conclusion, nutritional counseling sessions over five times are an effective and efficient approach to change dietary habits to improve exercise performance capacity. Furthermore, clients can have good dietary habits and learn how to manago muscle strength by behavior modification through multiple nutritional counseling sessions.

Reducing plate-waste for school lunches is an important strategy to guarantee adequate nutrition intakes by students as well as to protect the environment. This study was conducted to determine dieticians' perception of no-plate-waste day. The subjects were dieticians at 203 schools in Seoul and Kyeonggi-do. Among them, 132 schools (78.6%) operated no-plate-waste day once a week, 6.9% once a month, 10.8% twice a week, whereas 17.2% did not operate at all. According to dieticians, plate-waste per student on no-plate-waste day (mean 49.1 g) was lower than that on an ordinary day (mean 79.2 g). The most popular method to advertise no-plate-waste day was to notify it on the menu board (52.4%), followed by notifying it on the dining hall and the school website. The most frequently used reward on no-plate-waste day was a gift snack (67.3%), followed by complimentary stickers, awards, and GPA. The most common side effect of no-plate-waste day was students' abandoning foods (45.2%), followed by rejecting food and simplified menu. The most frequent barrier was insufficient recognition of necessity (39.3%), followed by shortage of manpower or budget and students and teachers' resistance. The dieticians at 35 schools without no-plate-waste day answered that they did not operate it due to 'no need perceived' and 'no budget' (31.4% and 31.4%, respectively). Based on this study, government and society should promote the need to reduce plate-waste by students and teachers as well as school administrators.
Purpose: Feeding children is a problem in pediatric intensive care units (PICU) and it is difficult to know the correct amount. The purpose of this study is to evaluate if prealbumin or retinol binding proteins (RBP) are effective relative to daily enteral nutrition, without being affected by severity of diseases or infections and can be used to follow up nutritional amount. Methods: This is a prospective observational study that includes 81 patients admitted to PICU in Akdeniz University with estimated duration >72 hours, age between 1 month and 8 years. Daily calorie and protein intake were calculated and prealbumin, RBP and C-reactive protein (CRP) levels were measured on the first, third, fifth and seventh mornings. Results: We find moderate correlation between daily calorie intake and prealbumin levels (r=0.432, p<0.001), RBP levels and daily protein intake (r=0.330, p<0.001). When we investigated the relationship between changes of prealbumin, RBP, CRP, calorie and protein intake during intensive care stay, we found that increase of Prealbumin and RBP levels are explained by decrease of CRP levels (r=-0.546 and -0.645, p<0.001) and not with increase of nourishment. Conclusion: Even adjusted for PRISM3, age and CRP, prealbumin and RBP are correlated with last 24 hours' diet. However, it is not convenient to use as a follow up biomarker because increase of their levels is related with decrease of CRP levels.
This study examined students' menu preferences as well as the job satisfaction and specific considerations concerning foodservice operation of dieticians and nutrition teachers at special schools for the disabled. Semi-structured interview questionnaires were sent to all of the 21 special schools with direct school food service in Gyeonggi-do, and 16 dieticians and nutrition teachers agreed to participate in this study. Among the various menu groups, the subjects perceived the meat group as the most preferred and the vegetable group the least preferred. They were generally satisfactory with their job and duty, and had a strong sense of belonging to the school. However, most of them answered that they needed more time for nutritional education and counseling. While most had pride and pleasure in their job, they expressed a desire to change the system to better fit with their roles as professional nutritionists. The content analysis revealed that the subjects mainly focused on safety issues in planning the food menu and were thus limited in selecting menu items. They also felt difficulty in menu planning due to various tastes and preferences, since special schools tend to consist of a wider grade range. However, most subjects reported little trouble in food distribution and food leftovers owing to practical support from teachers and parents. The necessity for education concerning table manners and obesity prevention was generally a shared opinion, and education programs for parents were also perceived as necessary to better understand the special considerations for developing proper eating habits in their child. The study findings provide useful basic data to improve the foodservice system at special schools.
The objective of the present study was to determine the prevalence and type of nutritional ergogenic aids use, and to determine the frequency, reasons for use of nutritional ergogenic aids. Thirty-four male bodybuilders (mean age = 27.0 years), twenty-four male weight lifters (mean age = 20.9 years) participated in the study. Participants completed a comprehensive survey detailing their usage patterns. In this study, 78.1% of bodybuilders and 79.2% of weight lifters reported using nutritional ergogenic aids. The most frequently taken nutritional ergogenic aids, in ranking order, were protein/amino acid powders (79.4%), multivitamin/minerals (67.7%) and creatine (67.6%) for bodybuilders, in contrast to sports drinks (100.0%), protein/amino acid powders (50.5%) and creatine (50.5%) for weight lifters. Over the half of the respondents, 79.4% of bodybuilders and 50.6% of weight lifters, used protein/amino acid powders to gain muscle mass and to stay healthy. Bodybuilders, 67.6% and weight lifters, 41.7%, used multivitamin/minerals to stay healthy and for energy. The intakes of most vitamin and minerals through diet and nutritional ergogenic aids were much greater than RDA. Vitamin $B_1$, vitamin $B_2$, niacin, vitamin $B_6$ and folate intakes were ranged at 400-900%. Vitamin C intake was 1285.4% (for bodybuilders) and 1322.6% (for weight lifters). The correct answer rate of nutritional ergogenic aids was 46.0% for bodybuilders and 52.0% for weight lifters. Both bodybuilders and weight lifters took highly nutritional ergogenic aids and it tended to be taken irrespective of scientific background. Specific sport nutrition education applicable to athletes, especially strength athletes, is recommended. The findings of this investigation could be used to enable the professionals (sports dietician and physician) to identity common misconceptions regarding nutritional ergogenic aids and to implement educational programs.
The purpose of this study was to investigate the effects of job stress on job satisfaction according to interpersonal relationship type among school dieticians and nutrition teachers. The online survey was conducted from Oct. 26th to Nov. 7th, 2017 in 2,000 randomly selected dieticians and nutrition teachers in the capital area. A total of 453 collected questionnaires were used for analysis. SPSS v.21.0 Statistical Package Program was used for the statistical process. For the results regarding interpersonal relationship type of dieticians, open-type (73.3%) was the highest, followed by self-assertive-type (23.0%), isolated-type (2.6%), and careful-type (1.1%). Regarding overall job satisfaction, 'human relation' was the highest, followed by 'job itself', 'working environment', and 'personal rating & welfare system', in that order. According to interpersonal relationship type, in the case of 'open-type' or 'careful-type', job satisfaction was relatively high. Regarding overall job stress, 'job demand' was the highest, followed by 'lack of reward', 'organizational system', 'interpersonal conflict', 'occupational climate', 'job insecurity', and 'insufficient job control', in that order. In accordance with interpersonal relationship type, overall job stress index was high in terms of 'self-assertive-type' or 'careful-type'. For the results of analyzing the correlation between job satisfaction and job stress index, all areas showed statistically significant negative correlations. Multiple regression analysis was performed to study the effects of job stress on job satisfaction mediating interpersonal relationship type. Job stress had different effects on job satisfaction in terms of 'open-type' and 'self-assertive type'. In conclusion, different strategies are needed for dieticians with different interpersonal relationship types to improve job satisfaction and to reduce job stress.
This study was conducted to investigate food purchasing management and the perception of school dietitians regarding food quality standards in the Chonbuk area of Korea. Self-administered questionnaires were collected from a total 205 dietitians and then evaluated using SPSS v. 11.5. The results are summarized as follows. Among the 205 school foodservice systems evaluated, 63.4% used a conventional system, while 36.6% were operated in a commissary manner. In addition, 64.9% of the schools had a menu cycle of 1 week (p<0.05) and 72.2% of the dietitians were responsible for the entire purchasing process (p<0.05). Moreover, a dietitian, school staff, foodservice staff, and parents participated in receiving and inspection of the food at 95.6% of the schools. Additionally, wholesalers and informal purchasing were preferred for purchasing food supplies. Moreover, 33.3% of dietitians in the commissary systems responded that they made Kimchi themselves instead of purchasing it (p<0.01). When the dietician's perception of food quality was evaluated, the average score was 3.33 based on a 5-point scale, although the scores differed significantly between dieticians working in conventional systems and those working in commissary systems (p<0.05). The scores for the quality standards related to the GMO agricultural and pesticide residues were the lowest. These findings indicate that it is necessary to develop standardized food quality and purchasing criteria and to provide education regarding these criteria to school dietitians to enable them to improve their knowledge regarding food quality standards and to implement effective purchasing programs.
Present status of school lunch service and satisfaction on it were surveyed by questionnaires with 636 elementary school students in Inchon city. School lunch service was considered positive in 68.3% of the objectives. Most of the students thought the amount of rice and side dishes appropriate.

The purpose of this study was to develop and evaluate a nutritional education program for preschool children in association with Center for Children's Foodservice Management, childcare facilities and home in order to provide nutritional knowledge and change food attitudes in children. The program was repeated three times using the same educational theme and consisted three steps. Step 1 involved visiting education with teaching tools by a dietician. Step 2 involved home education with a worksheet and participating in events with parents. Step 3 involved repeated education with a textbook by a preschool teacher education reports sent to the center. The subjects of this study were 3 to 5-year-old children at 89 childcare facilities located in Busanjingu. Interest in meals at childcare facilities, dietary guidance for parents of children, and dietary attitudes of children were evaluated before and after education. Number of parents interested in meals managed by childcare facilities (kitchen visiting, meals observation, progress of children's education) increased after education. Mean scores for meal awareness in parents in the form of three questions (proper food distribution, hand washing before mealtime, nutritional and hygienic satisfaction with meals) significantly (p<0.05) increased after education. Mean dietary guidance for parents' scores for all questions except table manner significantly (p<0.01) increased after education. Mean dietary attitudes for children in the form of six questions (try to eat various vegetable, eat meals without leaving, wash hands before mealtime, eat cleanly, reduce sodium intake and keep table manner) also significantly (p<0.001) increased after education. As a results, the nutritional education program applied in this study, positive influenced children's nutritional knowledge and dietary attitudes, and parents' dietary guidance of children.
The study was conducted to assess school dietitians' preferences for traditional foods, to determine the association with their perception and usage status, and to develop the strategies to increase its utilization of traditional foods in school lunches. The information was obtained by the self-administered questionnaire from the subjects, which were 198 dietitians in schools located in Seoul and Gyeonggi-do. According to the preference for traditional foods, subjects were distributed into three groups (High = 54, Medium = 128, Low = 16). The significances of differences between groups were determined using SPSS 12.0 at p < 0.05. Compared to the dietitians with lower (medium and low) preferences, those with high preferences answered that they had better knowledge (p < 0.001) for traditional foods, and served them more in school lunches (p < 0.01). Also, more dieticians in the high preference group not only felt that they need to train school administrators (p < 0.01) as well as themselves (p < 0.05), but also were currently providing students with the nutrition education on traditional foods (p < 0.05). The results presented the evidence suggesting that having dietitians with higher preference for traditional foods can offer an effective strategy to increase the opportunities for schoolchildren to be exposed to traditional foods. Development of the standard recipes for use in school lunches by the government or the association was answered as the best strategy to increase the use of traditional foods, regardless of the dietitians' preferences.
