We analyzed the effects of regular Jjimjilbang (Korean sauna) exposure on the cold tolerance in young and elderly females. Subjects were young (n=7) and elderly (n=7) females who had never had Jjimjilbang exposure experience. The Jjimjil training group was exposured in the Jjimjilbang 19 times per week. Jjimjibang exposure was limited to three times per day. Jjimjil activity was taken freely. To prove the effects of the cold tolerance, subjects were exposed to cold air ($12{\pm}1^{\circ}C,\;60{\pm}10%$RH). In these conditions, subjects were exposed for 30 minutes at which time rectal temperature, skin temperatures, clothing microclimate, energy expenditure, blood pressure and subjective sensation were measured. To prove the effects of the local cold tolerance, vascular hunting reaction was observed measuring the finger skin temperature while the left middle finger tip was immersed in cold water of $0^{\circ}C$ for 30 minutes. The results are as follows. According to repeated Jjimjil exposure, rectal temperature changes, peripheral temperature and energy expenditure were increased gradually in the cold climate chamber. Blood pressure, subjective sensation and vascular hunting reactions did not show any significant difference. In conclusion, regular Jjimjilbang exposure has negative effects on the ability of the body to improve its regulation of temperature especially in cold tolerance.

Objectives: The purpose of this study was to investigate how to manage food allergy of pre-school children, focusing on the current status of the food allergy in childcare facilities in Hanam which have less than 100 children. Methods: Targeting 159 preschool childcare facilities, survey was carried out for a month in March, 2015. Recovery rate was 66.7%. 106 surveys out of 159 were available for analysis using SPSS statistical program version 19.0. Results: Among 106 facilities, 58 (54.7%) reported that none of their children had a food allergy and 48 (45.3%) reported one more children had a food allergy. Total number of children having a food allergy was 71. Among them, the occurrences of food allergy in males were significantly more than that of the females (p<0.001). Further, children under 2 years of age had significantly more food allergy than the other ages (p < 0.001). The allergic inducing foods were nuts (23.3%), egg (17.8%), milk and dairy products (16.4%), fish and shellfish (13.7%), instant foods (12.3%), fruits (8.2%), soybean (4.1%), meat (2.7%), and cereals (1.4%) in order, and 6 children out of 71 were allergic to more than 2 food items. The clinical symptoms of the food allergy were a skin reaction (87.9%) and an oropharyngeal & respiratory reaction (12.1%). Majority of childcare facilities (80.3%) didn't serve alternative foods for children with food allergy. Necessity for food allergy education was significantly higher in facilities with food allergy issues than without such issues. Conclusions: The Center for Children's Foodservice Management need to educate workers of childcare facilities and parents about managing food allergy and enforce a plan to provide alternative menu to children with food allergies.

A systematic study was conducted to identify and isolate a serologically pertinent antigen with high specific activity and low cross reactivity from P.westermani antigen. Differential centrifugation of the homogenate yield three particulate and one soluble fractions ; the $480{\times}G$ pellet(Pw1), the $7650{\times}G$ pellet(Pw2) treated with n-butanol(Pw3), and $100000{\times}G$ supernatnat(Pw4). Comparison of antigenicity of these antigens, based upon differential centrifugation, to that of saline extract of P. westermani worm(SEP) was performed by SDS-PAGE and immunoblot techniques. The results obtained were as follows : 1) The ratio of absorbance value of ELISA against paragonimiasis positive pool sera to that of negative sera was highest when using Pw3 as antigen and that was lowest using Pwl. 2) Silver stained and SDS-PAGE of each antigen showed 34 and 13Kd band as common antigen band, but Pw2 didn't show clear band. 3) By immunoblot 55 and 34Kd bands using SEP and Pw4 showed strong positive reaction without cross reaction with sera from other helmenthic infections. Using Pw3, 10Kd band was observed as specific band. In conclusion, Pw3($100000{\times}G$ pellet urea soluble, treated with n-butanol) and Pw4($100000{\times}G$ supernatant) were usable for ELISA and immunoblot technique.

Paragonimus infection is prevalent in Korea, establishing several endemic foci. Kim(1969) reported an endemic area in Hyeonbuk Myeon. Yangyang-Gun, but thereafter no further epidemiologic study of Paragonimus infection was performed in the Gangweon-Do. Hoengseong-Gun is mountainous area which is located in the southwestern part of Gangweon-Do and borders with Hongcheon-Gun on the east, with Pyeongchang-Gun on the east, with Yeongweol-Gun and Weonseong-Gun on the south, and with Yangpyeong-Gun on west. The author carried out an epidemiologic study of Paragonimus infection by intradermal test with V.B.S antigen, and of intermediate host (crayfish) in Hoengseong-Gun, Gangweon-Do. The results are summarized as follows: 1. The positive skin test reaction to Paragonimus antigen was 14.5% from 2,807 examiness; 16.0% in male and 11.6% in female and no sex or age difference on the skin test positive reactions was noticed among the villages. 2. The positive skin test reactions were 31.3% in Gapcheon-Myeon, 20.5% in Cheongil-Myeon and 19.8% in Woocheon-Myeon. Primary school children in Byeongjibang-ri, Gapcheon-Myeon showed positive in 36.4%. 3. The prevalence by skin test reaction by social strata was 16.1% (226 out of 1,408) in primary school children, 12.8% out of 725) in middle school, 6.4% (11 out of 172) in high school students, and 15.3% (77 out of 502) in inhabitants of Heongseong-Gun. 4. Metacercarial positives of Paragonimus in crayfish were 20.9%. Through the survey results, it is postulated that Heongseong-Gun, Gangweon-Do is to be categorized as an endemic area of Paragonimus infection.

To investigate the effects of elevated $CO_2$ on the denitrifying bacterial community structure in a wetland soil, dynamics of bacterial community structure was explored in an artificial wetland ecosystem with one of three plant species (T. latifolia, S. lacustris, and 1. effusus) under two levels of $CO_2$(370 ppm or 740 ppm) after 110day incubation. For the analysis of bacterial community structure, functional genes such as nitrite reductase genes (nirS) were PCR-amplified followed by cloning of PCR products and screening by restriction fragment length polymorphism (RFLP). nirS gene fragments were amplified in all analyzed soil samples. Species richness estimated by the number of distinct phylotypes were 83 and 95 in the ambient $CO_2$ treatment and the elevated treatment, respectively. Two phylotypes (type 1 and type 2) were dominant in both of the treatments. Elevated $CO_2$ treatment increased species richness of denitrifying as well as changed a large proportion of denitrifier phylotypes compared to those of the ambient treatment. Overall, the data in this study suggested that the denitrifying communities in the wetland soil are diverse and that the richness of denitrifying bacterial community might be affected by elevated $CO_2$ treatment.

Topical agents including of steroids are easily exposed to Korean patients in community setting. Those topical agents must be use cautiously because can cause adverse drug reaction unlike other oral medication. We evaluate the using pattern topical agents of Korean in community setting. We performed a questionnaire survey in three different pharmacies (general community pharmacy, dermatology clinic oriented pharmacy, general hospital oriented pharmacy) and in three university town. The survey asked necessity of topical agents, the number of applications per day, application period, site, and exist of steroids ingredient, etc. Total 330 people was participated in the survey from May 1st to July 31st, 2014. We analysed the survey by the frequency of each question and cross-analysis of the compliance between general public and pharmacy groups. In results, Korean people used topical agents for sudden skin diseases (66.9%), was gotten by dermatologist's prescription (89.1%), and did not know their diagnosis (39.2%). The people applied topical agents on face (22.3%), less one half FTU (finger tip unit) per application (61.9%), less than one week (62.9%). Though they was received drug education from pharmacist (52.2%), did not heard about adverse effects (78.4%). And compliance of applied times in pharmacy group was higher than in-non-pharmacy group (56% vs 38%, p=0.002). The highest compliance between 3 pharmacy subgroup was general community pharmacy (76.3% vs 61.6%, 61.2%, p=0.039). Compliance of applied duration was no difference between groups. Majority of respondents did not know diversity of ingredients, potency, application area of topical steroids, and replied to feel some vague reluctance and to think so dangerous about topical steroids. In conclusion, Korean people in community use topical agents well but still some exposed to risk from topical agents.

Purpose: This study was performed in order to examine the effects of an smoking cessation counselling program for smoking cessation success. Method: Among a total of 468 persons who had ceased from smoking for 6-months and had visited the smoking cessation clinic of a public health center from January 2nd to December 31th in 2006, 61 in all who had a negative reaction in the urine nicotine check were selected for this study. Collected data were expiratory CO concentration, BMI, blood pressure, liver function, and lipid metabolism. These data were analyzed by descriptive statistics, repeated measured ANOVA and paired t-test with the SPSS/PC(Version 12.0) program. Result: There were significant changes in expiratory CO concentration, SBP, DBP, AST, ALT, and TG, but not in BMI, $\gamma$-GTP, TC, HDL-C, and LDL-C. Conclusion: This study showed that smoking cessation through a smoking cessation counselling program has partially positive effects for smoking cessation success. The results of this study show that the smoking cessation counselling program at the smoking cessation clinic of a public health center should be continued for smoking cessation success.

A food allergy is described an adverse immunological reaction to a food item. It is increasingly common problem among infants, children, teenagers, and adults worldwide. This study examines food allergy knowledge, attitudes, practices, and health consciousness among college students studying food and nutrition and childhood education. A total of 235 food and nutrition and childhood education college students participated in the survey. According to the results, 41.3% of the respondents were aware of legal obligations associated labeling food items for food allergy; 14.0% were diagnosed with food allergy by their doctor; and 10.2% knew about food allergy symptoms. Food and nutrition students were more knowledgeable than childhood education students. The mean for food allergy attitudes was 4.22, and the score for food and nutrition students was higher than that for childhood education students. The mean for food allergy behaviors was 2.16, and the score of food and nutrition students was higher than that of childhood education students. The importance of food allergens was significantly higher than performance. These results suggest that, to improve the management of food allergies in foodservice operations, education programs regarding food allergies should be provided food and nutrition and childhood education students.

Anthropophilic Culicoides were investigated in a rural community endemic for Mansonella perstans in Ijebu North area of western Nigeria between December 2003 and October 2004. Three hundred and fifty-nine adults of Culicoides fulvithorax collected by human bait in the morning were dissected for Mansonella perstans larvae, and $1.95\%$of infection rate was found. Seasonal abundance of C. fulvithorax was investigated by monthly biting rates, and showed that higher prevalence was observed in rainy season, with peak in September. Culicoides prevalence was positively correlated with rainfall and relative humidity, but not temperature. Human perceptions on the behavior of these biting midges were determined by interviewing 854 self-selected villagers, of which $86.5\%$ of the interviewees confessed having experienced Culicoides bites. Between 76.5 and $99.1\%$ of the various age groups complained body reactions to Culicoides bites. Itching was the most frequent body reaction. No interviewees associated Culicoides with transmission of any parasitic infections. The results showed need to adequately control Culicoides in the community.
