Health promotion program utilizing traditional korean medicine(TKM) is very unique modality uncommonly conducted throughout the world. Korea's TKM public health services went through initial stage from 2001 and spread throughout the country by 2003. 35 public health centers in the nation is appointed as 'TKM health promotion HUB' and in operation from 2007. But the program is still in the early state and evaluation of usage, satisfaction, and community service is still in demand. This study aims to verify current situations of TKM public health service by examining public awareness, usage, and satisfaction and suggest improvements based on findings. 2.5% of local residents were sampled and 1739 were chosen as subjects. Knowledge, attitude, satisfaction and others for TKM public health service were examined. TKM treatment service was most widely utilized(13.2%), followed by CVA prevention program(5.2%). For satisfaction level, CVA prevention program showed highest satisfaction(73.3%), closely followed by (Qi-gong program 63%). In general, awareness and utilization of TKM public health service were low but compensated by high satisfaction level. More active promotion and development of community specific programs should become available in the future.

The objectives of the present study were to (1) determine the susceptibility of Anopheles sinensis to Korean isolates of Plasmodium vivax, (2) establish a method to collect large quantities of P. vivax sporozoites for use as antigen in seroepidemiological studies, and (3) investigate the characteristics of Korean isolates of P. vivax sporozoites. Females of Anopheles sinensis were collected at non-epidemic area, Seokwha-ri, Cheongwon-gun and Chungcheongbuk-do using tent-trap methods coupled with dry ice. The females were artificially infected with gameiocytes of P. vivax using blood obtained from P vivax malaria patients. Individual mosquitoes were infected using either a parafilm-covered glass feeding apparatus or were allowed to feed on naturally infected volunteers. Mosquitoes were sacrificed between 16 and 18 days post-feeding and an enzyme-linked immunosorbent assay (ELISA) was used to detect sporozoites. Four (33.4%) of 12 mosquitoes, which were fed on naturally infected volunteers directly, were positive for sporozoites. In cases, the mosquitoes allowed to feed on whole blood which were extract from three different patients with heparin treated vacuutainers using a parafilm-covered glass apparatus. Two of 55 (3.6%) were positive which blood sample was maintained at room temperature for 8 hours, 1 of 68 (1.5%) was positive which blood was maintained at $4^{\circ}C$ for 24 hours and 1 of 47 (2.3%) was positive at 4$^{\circ}C$ for 48 hours. The mean number of sporozoites was estimated about 818 (n=8; range of 648-1,056) based on optical density values of ELISA.

The effect of obesity on the drug-metabolizing enzymes remains an important issue for clinician since obesity is a world wide epidemic problem. However, little is known about the effects of obesity on flavincontaining monooxygenase (FMO) production and activity. We show here for the first time that in vivo FMO activity determined by urinary ranitidine (RA) metabolites ratio in human, was higher in subjects with a high body mass index (BMI, kg/$m^2$, 21.97-30.32) than in those with an intermediate BMI (range 19.38-21.83). Moreover, there was a significant correlation between FMO activity and BMI in 209 subjects. In high fat diet-induced obese mice, we also observed that the hepatic expression of FMO (225% of lean mice) and the activity measured by the RA Noxidation rate ($513{\pm}58.1$ vs. $349{\pm}66.0$ pmol/hr per mg protein) were significantly higher than in lean mice fed a control diet. Unknown factors rather than leptin or insulin appeared to regulate the hepatic FMO production. Thus, FMO activity may be increased in obese or overweight individuals. Moreover, the regulation of FMO activity in subjects with morbid obesity, with or without complications and its clinical implications, should be investigated further.

Objectives : To estimate mumps incidence during the study period and to evaluate the completeness of case reporting. Methods : Capture-recapture methods, originally developed for counting wildlife animals, were used. The data sources were 1) the National Notifiable Communicable Disease Reporting System (NNCDRS; 848 cases), 2) the School Health Reporting System, temporarily administered by the Division of Education (SHRS; 1,026 cases), and 3) a survey of students (785 cases). We estimated the number of unobserved mumps cases by matching the three data sources and fitting loglinear models to the data. We then determined the estimated total number of mumps cases by adding this to the number of observed cases. Completeness was defined as the proportion of observed cases from each source to the total of estimated cases. Results : The total number of observed cases was 1,844 and the total number of estimated cases was 1,935 (95%, CI: $1,878\sim2,070$). The overall completeness was 43.8% of the NNCDRS, 53.0% of the SHRS, and 40.6% of the survey. However, completeness varied by area and age. Conclusion : Although the completeness of NNCDRS data appeared higher than in the past, it is difficult to generalize this result In Korea, it is possible to estimate the size of health hazards relatively cheaply and quickly, by applying capture-recapture methods to various data using a multiple data collection system.

In the present study, methods of the reverse transcription-polymerase chain reaction(RT-PCR) were evaluated for the rapid detection and differentiation of transmissible gastroenteritis virus(TGEV), porcine epidemic diarrhea virus(PEDV) and rotavirus in piglets suffering from diarrhea. For the purposes, the PCR conditions were first confirmed for the amplification of VP7 gene of rotavirus and N gene of TGEV and PEDV using each specific primers and their annealing temperature. Multiplex RT-PCR methods were further determined to distinguish these viral infections and the results are as follows. For the specific amplification of these viral genes, the reliable PCR condition was determined as 30 cycles of reaction consisting each 1 min of denature at $94^{\circ}C$, annealing at $42^{\circ}C$ and polymerization at $72^{\circ}C$ with 1.0 mM $MgCl_2$. It was able to differentiate these viral infections in the intestines and feces of piglets suffering from diarrhea by duplex PCR for TGEV and PEDV and single PCR for rotavirus with a primer-annealing temperature of $42^{\circ}C$. When the multiplex RT-PCR were undertaken for the field samples, 17 cases of PEDV and 5 cases of rotavirus infections were differential diagnosed in a total of 92 samples of intestines and feces of the piglets with diarrhea.

Periodic outbreaks of Newcastle disease (ND) caused by velogenic viscerotropic ND virus (vvNDV) has become a major concern in Korea nowadays. Throughout last epidemic, the winter season in 2000, most chicken flocks infected early, under 2-4 weeks of age, showed high mortality up to 50-100%. Serum samples collected from 201 breeder, 284 layer and 112 broiler chicken flocks were examined to evaluate the efficacy of various vaccination methods and programs routinely used for mass vaccination in the field poultry farms. Despite repeated live vaccination, most poultry flocks vaccinated by drinking water route using nipple water supply system failed to produce solid active immune response to NDV during the growing time. In the present study, we applied the spray vaccination technique using Ulvavac or Desvac sprayer to the experimental poultry flocks and examined the efficacy of live vaccination effects induced by it under field condition. Measurable antibody to NDV as well as early protection against vvNDV challenge were found in poultry flocks vaccinated by spray route. Further, we did not found significant post vaccination reactions caused by spray vaccination if properly administered. These data indicate that the spray vaccination will be safe and reliable mass vaccination method for the prevention of ND.

In this study, the genetic diversities of multi-resistant Salmonella typhimurium (ST) isolates were analyzed via the application of both pulsed field gel electrophoresis (PFGE) and Polymerase chain reaction (PCR) analysis methods, using 6 kinds of primers (REP, ERIC, SERE, BOX, P-1254 and OPB-17). And their discriminative abilities (DA) were also compared in order to determine the most effective and reliable analysis method. 118 S. typhimurium isolates, cultured from diverse animals and human patients in Korea beginning in 1993, were analyzed and subjected to a comparison of Simpson's index of diversity (SID), using both PFGE and PCR methods. PFGE by XbaI enzyme digestion allowed for discrimination into 9 pulsotypes, with high SID values (0.991) on the genomic DNA level. This shows that PFGE is a very discriminative genotypic tool, and also that multiple clones of S. typhimurium isolates had existed in domestic animals and humans in Korea since 1993. However, we could ultimately not to trace the definitive sources or animal reservoirs of specific S. typhimurium isolates examined in this study. Depending on the SID values, the combined method (7 kinds of method) was found to be the most discriminative method, followed by (in order) SERE-PCR, REP-PCR, ERIC-PCR, PFGE & OPB-17 (RAPD), P-1254 (RAPD), and BOX-PCR at the $80\%$ clone cut-off value. This finding suggests that the REP-PCR method (which utilizes 4 primer types) may be an alternative tool to PFGE for the genotyping of S. typhimurium isolates, with comparable cost, time, and labor requirement. The establishment of a highly reliable and discriminatory method for epidemiologic analysis is considered necessary in order for researchers to trace the sources of specific pathogens and, consequently, to control and prevent the spread of epidemic S. typhimurium isolates to humans.

Microsporidia in humans emerged with the AIDS epidemic. Enterocytozoon bieneusi is the most significant species' and causes chronic diarrhea, wasting, papillary stenosis, acaculous cholecystitis, bile duct dilatation and sclerosing cholangitis and is responsible for $30-50\%$ of all cases of in people with AIDS. Microsporidiosis has been reported in immunosuppressed, and in immunologically normal individuals. Variety of study has revealed the mode of transmission and possible reservoir of E. bieneusi. Its sites of infection suggest that transmission occurs by ingestion. Transmission has been speculated to occur via infected animals to human, person to person. There is evidence that E. bieneusi occurs in pigs, monkeys, and possibly other animals such as cattle, dogs, cats, llamas and rabbits. E. bieneusi from infected humans has been transmitted experimentally to macaques and to pigs. These observations reflect indirectly the zoonotic nature of E. bieneusi and indicate that cross species transmission is a real possibility. Meanwhile, In recent report, thirty-two percent of the pigs were found to be positive with rates higher over the summer months in US.

Dengue Fever(DF) and Dengue haemorrhagic fever(DHF) has become a major international public health concern. Dengue Fever(DF) and Dengue haemorrhagic Fever (DHF) is also still the major health problem of Thailand, although many campaigns against it have been conducted throughout the country. GIS and Remotely Sensed data are used to evaluate the relationships between socio-spatial, environmental factors/indicators and the incidences of viral diseases. The aim of the study is to identify the spatial risk factors in Dengue and Dengue Haemorrhagic Fever in Sukhothai province, Thailand using statistical, spatial and GIS Modelling. Preliminary results demonstrated that physical factors derived from remotely sensed data could indicate variation in physical risk factors affecting DF and DHF. The present study emphasizes the potential of remotely sensed data and GIS in spatial factors affecting Dengue Risk Zone analysis. The relationship between land cover and the cases of incidence of DF and DHF by information value method revaluated that highest information value is obtained for Built-up area. A negative relationship was observed for the forest area. The relations between climate data and cases of incidence have shown high correlation with rainfall factors in rainy season but poor correlation with temperature and relative humidity. The present study explores the potential of remotely sensed data and GIS in spatial analysis of factors affecting Dengue epidemic, strong spatial analysis tools of GIS. The capabilities of GIS for analyst spatial factors influencing risk zone has made it possible to apply spatial statistical analysis in Disease risk zone.

No.87 Sogong-dong where is the Chosun hotel stand. There was the Nambeol-gung(south ern royal villa) which had been a reception hall for enboys of the toadied country before Hwangudan圜丘壇 being set up in the year 1897. The site of the Nambeol-gung was Gyeongjeong慶貞 princess's a lot for house in the early 15th century. But after princess's death, it occurred property dispute between her son and four daughters. As a result of the dispute, a lot and a house of all the princess's properties reverted to the government. At reverted this lot was established a big royal villa in the year 1583 and that royal villa was granted to Uian prince. The villa reverted to the government again when the Uian義安 prince was dead in 12 years old by an epidemic. After the Imjin Invasion壬辰倭亂, another houses and buildings got to be role as a palace because of all the palace in the capital was burnt down to ashes. Among others Nambeol-gung was brought into play as the royal audience chamber. As well as, the villa became brought out role as a reception hall for enboys of the toadied country instead of a damaged reception hall the Taepyong-gwan太平館. In period when the envoy didn't come, the Nambeol-gung was used to extraordinary office of government like Dogam都監. This situation is to mean that the Nambeol-gung is not the royal villa any more. Because of the Nambeol-gung was built as a royal villa, that spaces were composited like space of house and palace. But this spatial composition and spatial name were not fit to hold a ceremony of government office. After all, Nambeol-gung was used change only the spatial name conform to ceremony of office keep up the spatial composition.
