Purpose: Height-specific blood pressure (BP) is the standard parameter used to diagnose childhood hypertension. However, there has been some argument that weight may be a better variable than height in the reference BP standards. Therefore, before assessing the BP status using the reference BP standards, a basic understanding of the fundamental association of weight and height with BP is required. Methods: In the present study, we analyzed the correlation of BP with height and weight in Korean adolescents (age, 10-19 years), using data from the Korean National Health and Nutrition Examination Surveys (2009-2011). Results: Systolic BP (SBP) was more closely correlated with weight than with height in the normal weight (body mass index [BMI], ${\leq}85th$ percentile) and overweight (BMI, >85th percentile) groups and in the normal waist circumference (WC, ${\leq}90th$ percentile) and high WC (>90th percentile) groups in both sexes. Diastolic BP (DBP) had a higher correlation with height than with weight in the normal weight and normal WC groups, whereas weight was more closely associated with DBP than height in the overweight and high WC groups in both boys and girls. Conclusion: In Korean adolescents, weight had a greater effect on SBP than height in both the normal weight and overweight groups. DBP was mainly affected by height in the normal weight group, whereas weight was the major determinant of DBP in the overweight group. Therefore, it may be necessary to consider weight in the establishment of reference BP standards.

A research was conducted on Seoul regional elementary, middle, and high school nutritionists to study about their perception of HACCP control standards & performance conditions and sanitation & safety inspection, to seek for more efficient methods of school meals' sanitation system settlement. All surveys were distributed and collected via email. A total of 305 survey papers were collected, and out of these, 300 school results were analyzed. As for CCP 1 performance conditions, 43.3% of the nutritionist put emphasis on temperature control for cooking duration and 71.0% said that they manage both temperature and PHF food control. In CCP 2 stage, 65.8% of the nutritionists maintained the food's temperature, and 56.7% documented the recordings after cooking. A total of 79.3% of the schools scored above 90 points on school meal sanitation & safety inspection, 3.72 points on necessity for revisions, 3.38 points on objectivity, and 3.34 points on reliability. As for these results, a clear CCP control criteria as well as training must be set. Also, because the necessity of revision for sanitation & safety inspection is higher than reliability and objectivity, appropriate complementary measures must be taken.

The development of food poisoning prevention guidelines aims to prevent food poisoning in advance and improve the safety of children's meals through hygiene management of children's feeding facilities, especially infants' facilities. Therefore, the composition of the content should be designed so that it can be fully understood from the point of view of the layperson. In terms of meal service management, various standards must be fully reflected and reviewed to increase utilization in the field. Daycare centers and kindergartens have different administrative agencies, similar application laws and guidelines, but different parts exist and various types of facilities, so management standards are often ambiguous. Therefore, such management requires easy guidance, not special guidance, and it should be universally applicable to any facility. Prior studies have shown that the management of meal facilities is the most efficient, but it is difficult to hire and deploy specialists due to the operation of children's meal facilities, so guidance, facilities managers and workers need to voluntarily practice them. It is time to prepare hygiene guidelines that reflect the characteristics of these children's cafeterias, and it is necessary to prepare and utilize guidance suitable for reality until it is institutionalized for the deployment of manpower exclusively for meals.

The Korea School Lunch Program mandates that school meals should safeguard the health and well-being of our children. School meals provide a nutritious diet that contains at least ⅓ of the daily Recommended Dietary Allowances of necessary nutrients at reasonable prices. This study was performed to assess the nutritional management of primary school meals, and to provide basic data for improvement of school meal nutritional guidelines. Three hundred and thirty six dietitians who worked at primary schools were recruited using a stratified sampling method. A survey was done by e-mail with a set of questionnaires about nutritional meal management. During school lunch planning, dietitians referred nutrition standards with priority, followed by students' food preferences and food hygiene. They considered energy as a most important nutrient during primary school lunch planning, followed by protein and calcium. Protein is usually over-served, whereas iron, vitamin A and calcium are usually under-served during primary school meal planning. For first and second grade primary students, grains, meat and vegetable side dishes seemed to be large compared to their eating capacity. Over 92% of school dietitians agreed the needs of food group standards for primary school lunch program. For making a checklist of the school lunch program, energy, protein and calcium were highly recommended, and meat.fish.egg group, vegetable.fruit group and dairy group were also highly recommended by school dietitians. Cooking method was also highly recommended. School dietitians proposed that remodeling of school kitchens and new cooking machine were the most important factors for improving school lunch system. These results suggest that food standards should be established for health-oriented nutritional management of primary school lunch programs. Nutritional checklists could include nutrient-rich foods and food groups, and items about cooking methods.

Although it is increasing the number of day-care centers in Korea, but the quality of food and nutrition service are not increased sufficiently. The purpose of this study was to investigate the current practices of food and nutrition service in day-care centers. Questionnaire were sent to the directors of 750 day-care centers and 253 returned the complete answers. Staffing structure revealed that only 13% of the facilities had a dietitian. And compared with centers without a dietitian, there were more centers having nutritional standards, using facilities for service, and having long-term planning of meals in centers with a dietitian. In the using of foodservice budget, the centers having dietitian consumed more money for subsidiary dishes than for the staples. All centers needed increment of supplementation for the cost of foodservice and for hiring a dietitian. To improve the quality of food and nutrition services in day-care center, foodservice practices have to be conducted by professional personnel and to confirm the standard of service and to inspect the management of food and nutritional service.

Hygienic standards for pizza specialty restaurant located in Seoul during summer, 2000 were established based on HACCP concept by measuring temperature, time, pH, $A_{w}$ and microbiological assessments of pizza, and evaluation of hygienic conditions of kitchens and workers. Kitchen and worker conditions were average 1.2 and 1.0 (3 point Sly's scale), respectively, Microbial contaminations occurred at $5-60^{\circ}C$, pH above 5.0, and $A_{w}$ (0.93-0.98). Microbial assessments for pizza processing revealed $1.5{\times}10^{2}-3.9{\times}10^{8}\;CFU/g$ of TPC and $0.5{\times}10^{1}-1.6{\times}10^{7}\;CFU/g$ of coliforms, exceeding standards ($TPC\;10^{6}\;CFU/g\;and\;coliform\;10^{3}\;CFU/g$) established by Solberg et al., although significantly decreased after baking. S. aureus was not discovered, but Salmonella was found in onions. Tools and containers such as pizza cutting knife, topping container, serving bowl, pizza plate, working board, and dough kneading board contained $6.2{\times}10^{2}-1.1{\times}10^{9}\;CFU/g$ of TPC, $2.0{\times}10^{1}-6.2{\times}10^{3}\;CFU/g$ of coliforms. Workers' hands contained $3.1{\times}10^{4}\;CFU/g$ of TPC and S. aureus as compared to safety standards of Harrigan and McCance (500 and 10 CFU/g of TPC and coliforms per $100cm^{2}$). CCPs (critical control points) were determined as receiving, topping, and baking according to CCP decision tree analysis. Results suggest purchase of quality materials, careful monitoring of time and temperature, hygienic use of tools and utensils, and sanitary practicer by workers are recommended as control points for safe pizza production.

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.
