This study investigated the performance of hygiene management according to the capacity and food cost of foodservice in kindergartens as a measure of kindergartens foodservice hygiene management. Dietitians from the education office visited 50 kindergartens under the control of Dongbu District Office of Education during January, 2011. Kindergartens were 11 public and 39 private institutions. Over half of kindergartens (n=27) provided foodservice to 50~99 children. About 21 kindergartens had a foodservice cost per student per day of 2,000 won. Regarding personal hygiene, 'whether to wear an accessory or have a manicure' showed the best performance. 'Whether to have their health examined once every 6 months or keep their health records in 2 years' was rarely performed. For food materials, 'whether to buy food appropriate for the quality control standard of food materials' showed the highest performance. The highest performances for storage management of food materials and handling of food was 'whether to store goods within butlery at intervals more than 30 cm from the ground' and 'whether to heat and cook food more than $74^{\circ}C$', respectively. The highest performance for distribution of food and management of facilities was 'the hygienic management of cooking tools and facilities' and 'the proper installation of air-conditioning, heating and ventilation facilities', respectively. The results of this study show that capacity and food cost had the strongest effects on performance of personal hygiene. Especially, smaller facility size could increase performance of foodservice management.

Inter-simple sequence repeat (ISSR) analysis were used to assess genetic diversity among 18 genotypes of watermelon (Citrullus lanatus Thunb.) including breeding lines and commercial varieties. The 21 ISSR primers selected from 100 primers were showed the amplification of 105 reproducible fragments ranging from about 200 bp to 5000 bp. A total of 58 DNA fragments were polymorphic with an average 2.7 polymorphic bands per primer. The polymorphic primers were divided into 18 anchored primers and 3 non anchored primers. All of the anchored primers were di-nucleotide repeat motif, and was more polymorphic than non anchored primers. Eighteen watermelon genotypes were classified into two large groups. Clustering was in some accordance with the division of fruit shape into 18 watermelon. Therefore, ISSR markers may be suitable for variety discrimination and for constructing a linkage map of watermelon.

Objectives: Stress hormone (cortisol) can be used to analyze psychological and physiological changes and healing effects before and after in blood and saliva. Here it is applied to scientifically validate the effects of the healthy forest experience in Deogyusan Mountain National Park. Methods: A healthy forest experience program was provided to college students (males and females) at Deogyusan National Park. Stress, hormones (cortisol), blood pressure, pulse, oxygen saturation and stress, anxiety, and depression were measured. This study was designed to objectively analyze the effects of stress hormones before and after. Results: Depression, stress, anxiety, and satisfaction with the forest experience program in Deogyusan National Park were very high in reliability in terms of Cronbach's Alpha: depression scored 0.910, stress 0.558, anxiety 0.934, program satisfaction 0.826, and program effectiveness 0.894. Conclusions: In this study, we utilized the Healthy Forest Experience Program and the 'Health and Medical Center Health Record Book' of the Health Forest Experience Program (Ministry of Environment's Environmental Education Certification Program). In the future, we will seek ways to utilize saliva since it is easier to collect than blood samples and apply the stress hormone cortisol as a saliva authentication program. In addition, by implementing ecological welfare programs in which nature and human beings coexist through systematic preservation and restoration, the national park management can utilize ecological, scenic and cultural services wisely. We expect to be able to provide exploration and welfare services.

This study was performed to deduct the extension possibility of the standards establishment for $NO_2$, $O_3$, Asbestos, Radon, total volatile organic compounds (TVOC) excluded in the indoor air part of Industrial Safety Acts in Korea. The air pollutants were sampled for 30 office buildings from August to September, 2005 in the metropolitan area. The airborne concentrations of $NO_2$, $O_3$, Radon and TVOC were 0.0092 ppm, 0.0035 ppm, 0.57 pCi/L and $423{\mu}g/m^3$, respectively. The management plan and reduction methods is required in the aspect of indoor air quality(IAQ) because the emission sources of those also exist in indoor as well as outdoor even though those were not exceeded the standards of the Ministry of Environment in Korea. The standard for TVOC in the new and remodeling office has to be established based on the risk assessment when hazard index exceeded "1" in the worst case scenario. In the state of art, the management of each volatile organic compounds has a difficulty due to not enough data for toxicological reference. Therefore, it is suggested that first of all, the standard for TVOC be established and then expanded to each materials for decision-making of improvement of IAQ in office.

We described an estimation of measurement uncertainty in quantitative analysis of 11-nor-9-carboxy-${\Delta}^9$-tetrahydrocannabinol (THCCOOH), the major metabolite of ${\Delta}^9$-tetrahydrocannabinol, in urine sample by solid-phase extraction (SPE) and GC/MS detection. The analytical results were compared and the different contributions to the uncertainty were evaluated. Inter-day and inter-person validation were performed using statistical analysis of several indicative factors. Measurement uncertainty associated with target analyte in real forensic samples was estimated using quality control (QC) data. Traceability of measurement was established through traceable standards, calibrated volumetric glassware and volume measuring device. The major factors of contribution to combined standard uncertainty, were calibration linearity, inter-day repeatability and inter-person reproducibility, while those associated with preparation of analytical standards and sampling volume were not so important considering the degree of contribution. Relative combined standard uncertainties associated with the described method was 12.05% for THCCOOH.
