Body shape of a child in elementary school is distinguished by physical differences in the form of low weight, normal weight and obesity, which are influenced by various periodic environments. In particular, there are hardly any patterns for obese children in elementary school to choose. To this end, the purpose of this study is to supplement the problems with the production lines of the companies for children's patterns as well as an analysis on the physical characteristics of obese children and to suggest the patterns appropriate to obese children. This study employed obese children from the 3rd- to 5th-grade elementary school students whose number has been rapidly increasing and conducted a questionnaire regarding the draft of the patterns for obese children on their mothers and the makers of children's clothing. Based on the results, the study compared and analyzed ordinary children's patterns to the patterns in question by suggesting a dimension system for Korean obese children. The results are as follows. The obesity rate of the children in elementary school has been grown in significant numbers every year, whereas obese children's sense of self-identity and degree of satisfaction with their patterns appeared to be much lower than other ordinary children in the peer group; also, the satisfaction level their mothers with their children's patterns appeared to be low. In order to verify the degree of the children's satisfaction with their patterns, the study suggested a dimension system for the obese children and displayed appropriateness by comparing the children patterns from ordinary companies and the patterns in question.

To survey the prevalence of Sarcocystis infections, 210 heart samples were collected from Korean native cattle (Bos taurus coreanae) at an abattoir in Daejeon Metropolitan City, Republic of Korea. Sarcocysts were detected form 31 specimens (14.8%) and identified as Sarcocystis cruzi via transmission electron microscopy. The wall of S. cruzi has flattened protrusions that did not contain fibrils or microfilaments. The protrusions arose irregularly from the base, contained a fine granular substance, lacked internal microfilaments, and measured approximately $0.21-1.25{\mu}m$ in length and $0.05-0.07{\mu}m$ in width. Sequence analysis revealed 99.5% homology to S. cruzi. This is the first report on the prevalence of S. cruzi in native cattle from the Republic of Korea.

Method: Questionnaire was conducted by convenience sampling for 220 office workers belonging to H Group located in Seoul Metropolitan city over about 5 weeks between December 17, 2007 and January 20, 2008. The questionnaire for this study was constructed in consideration of general characteristics of the subjects, behaviors of the dental management. and scaling. The collected questionnaires were electronically processed using SPSS 12.0. Result: The followings are the findings of this research. First, in general, scaling is experienced by male unmarried worker in their 40s. whose monthly average income is 1.00-1.99 million won and have little interest in the hygiene of their mouth and, consequently. whose hygiene of the mouth is not good. Second, scaling is experienced once every six months by the worker in their 50s or older, who are college graduates and have much interest in the hygiene of their mouth and, consequently. whose hygiene of the mouth is good. Third. scaling is not periodically conducted because of high costs of it in terms of almost every parameter of general characteristics. Fourth, they have correct knowledge of scaling since they regard it as 'removing of plaque and tartar' in terms of every parameter of general characteristics. Fifth, the workers' sex (pE0.05), hygienic condition of the mouth (pE0.05) and knowledge of scaling (pE0.001) have a significant effect on their scaling experience. Conclusion: It is considered that dental health management should be continued by training of the importance of prevention through scaling as measure for dental health promotion of workers.

An attempt is made to analyse characteristic features of heavy rainfalls which occur at the metropolitan area of the Korean peninsular the on- and off- Changma season. For this, two representative heavy rainfall episodes are selected; one is the on-Changma season wherein a torrential rain episode happened at Goyang city on 12 July 2006, and the other is the off-Changma season, a heavy rainfall event in Seoul on 21 September 2006. Both recorded considerable amounts of precipitation, over 250mm in a half-day, which greatly exceeded the amount expected by numerical prediction models at those times, and caused great damage to property and life in the affected area. Similarities in the characteristics of both episodes were shown by; the location of upper-level jet streak and divergence fields of the upper wind over heavy rainfall areas, significantly high equivalent potential temperatures in the low atmospheric layer due to the entrainment of hot and humid air by the low-level jet, and the existence of very dry air and cold air pool in the middle layer of the atmosphere at the peak time of the rainfall events. Among them, differences in dynamic features of the low-level jet and the position of rainfall area along the low-level jet are remarkable.

A survey was conducted to investigate the attitudes of public officials related to food hygiene toward food safety. The official groups were divided into four sub-groups based on their area, agency, gender and age. Response of each group to the survey was statistically analysed. The survey's results showed that most of them (87.0%) were satisfied with a domestic level of food hygiene. But, some of then (29.8%) considered unsatisfactoryly on safety of the food they eat. Their response to food safety did not statistically significant between each group of area, agency and age but, in case of gender, female group showed stastically more negative attitude to food safety than male one (P<0.05). All groups chose residues of chemical substances such as pesticides and food additives as the most potential food risk factor followed by foodborne pathogens, heavy metals and animal drug residues. The results are not consistent with the scientific judgement. Therefore, more education and information were needed fro these groups. They pointed out food manufacturer as a responsible group for poor food hygiene (48.7%). In addition, food manufacture and processing were selected as main business types with the lowest level in the food hygiene but official, working in the area of the central government and Seoul metropolitan city, pointed out food services establishments as the poorest hygiene one (P<0.01). This results suggested that education and information to let mind of responded groups change, working in this part, and governmental financial support are needed to improve hygiene level of food manufacture and processing (70.3%). They also chose HACCP as the most effective way for improving the level of food hygiene followed by Recall, PL (Product Liability), monitoring, labeling and increasing of number of company with good manufacture and processing (GMP).
