As an increasing interest in GIS, it has been used in many fields such as urban planning, environment, military. Due to the ubiquitous internet, the number of users are able to take advantage of GIS without the constraints of time and space. However, local government such as Cheonan city does not serve local spatial database properly to user. Therefore, this research proposed the methodologies that can be served effectively local spatial database by combining internet and GIS. To achieve the research purpose, open APIs of Google Earth and mashup techniques were used. Key Words : Geographic Information System, Spatial Database, Open API, Mashup

This study attempted to determine the degree of asbestos release from the aging slate roof by comparing the asbestos content in the slate roof rain gutter with a colored steel plate (tin plate) over the slate roof. Four slate roof houses located in Haengmok-ri, Asan-si, Chungcheongnam-do, and one house constructed with a colored steel plate on the slate roof were selected to collect the sediment of the roof rain gutter. The asbestos fiber content was calculated by a point counting method using a polarization microscope after pretreatment with conversion treatment and hydrochloric acid treatment. The average asbestos content of the four slate roof rain gutter were 1.89%. However, asbestos was not detected in the Slate covering roof rain gutter, which were constructed on the slate roof. Asbestos fiber content was the highest at 2.89% in the slate roof rain gutter installed in 1976, followed by 2.44% in 1953. From the above results, it is necessary to minimize secondary damage as asbestos fibers released from slate roof houses to the surrounding atmosphere or leaked from slate roofs as rainwater may cause soil pollution and seriously affect residents' health. Although covering with colored steel plates (tin plates) has been shown to prevent the leakage of asbestos fibers to some extent, it is believed that a policy alternative to remove the slate roof as soon as possible is needed to solve the fundamental problem.

Purpose : In previous researches, we learned that exercising promotes physical fitness ,strength and positive change in the physical satisfaction level but reviewing previous researches, there was a limit in our finding as it was based on a singular physical activity or exercise and we could not exactly find out which exercise provided the most physical change and satisfaction level. Therefore, the purpose of this study was to find out effects of physical fitness and satisfaction according to participate in exercise method(circuit strength, weight bearing program and badminton). Method: Twelve college students participated exercise program(circuit strength program : n=4, weight bearing program : n=4 and badminton : n=4) who measured 20m PACER, push-up, grip strength, sit-up and sit-reach and body composition, and satisfaction which ``Sports Participants Satisfaction Questionnaire`` developed by Yoo et al(2010). The questionnaire covered improving physical function (3), improved exercise capacity (3), promote social and psychological benefits (3), two healthy living (2) which consisted of total of 14 questions with 5 multiple choices. With regard to the body satisfaction level survey, we have used the BSQ: Body Shape Questionnaire developed in 1987 by Cooper, Taylor and Fairvurn. Park, Eun-ah and Noh, Young-kyung was edited the BSQ questionnaire for this research. The body satisfaction level survey consisted of four sub-variables and a total of 27 questions. Result: First, there is a high level of increase overall in physical strength measurement results especially in sit-ups, flexibility, push-ups and cardiovascular endurance. However, there was little difference between the groups in terms stamina changes while we could not compare physical strength changes based on the type of exercise. Second, there was a slight decrease in weight, BMI, waist and hip circumference with regard to physical changes. However, the physical changes between groups were small while there was no physical change based on the type of exercise. In addition, the was no changes in the level of satisfaction based on after and before exercising while there was only slight difference exercise groups. Third, overall satisfaction level showed significant increase among the exercise groups while the health exercise showed the highest level of satisfaction followed by badminton and circuit training. In terms of exercise satisfaction level by category, physical function improvement and improved exercise capacity showed the highest level of increase and there was little difference in the exercise satisfaction level based on the exercise type. Fourth, if we look at the satisfaction level for physical strength change, satisfaction level was high for strength and agility category but showed no changes between exercise groups. Conclusion: This research is the study of the satisfaction level and changes in physical and physical strength based on three different exercises for different exercise groups. Based on the results of the study, exercising regularly helps increase the overall physical level in all exercise groups and the satisfaction level gradually increases. However, there was little difference between the exercise groups and this research was unable to verify the difference based on the exercise groups. Since the research was limited to 12 participants, a follow-up research should be conducted based on an extended level of participants.

We investigated the inhibitory effect of escitalopram, a selective serotonin reuptake inhibitor (SSRI), on voltage-dependent $K^+$ (Kv) channels in freshly separated from rabbit coronary arterial smooth muscle cells. The application of escitalopram rapidly inhibited vascular Kv channels. Kv currents were progressively inhibited by an increase in the concentrations of escitalopram, suggesting that escitalopram inhibited vascular Kv currents in a concentration-dependent manner. The $IC_{50}$ value and Hill coefficient for escitalopram-induced inhibition of Kv channels were $9.54{\pm}1.33{\mu}M$ and $0.75{\pm}0.10$, respectively. Addition of escitalopram did not alter the steady-state activation and inactivation curves, suggesting that the voltage sensors of the channels were not affected. Pretreatment with inhibitors of Kv1.5 and/or Kv2.1 did not affect the inhibitory action of escitalopram on vascular Kv channels. From these results, we concluded that escitalopram decreased the vascular Kv current in a concentration-dependent manner, independent of serotonin reuptake inhibition.

Foot-and-mouth disease (FMD) is an economically important and highly infectious viral disease in most parts of the world and is predominantly controlled by immunization strategy. The removal of nonstructural proteins (NSPs) is an important process of FMD vaccine because vaccinated and naturally infected animals can be distinguished by the presence of NSP antibodies in FMD serological surveillance. Polyethylene glycol method is conventionally used to eliminate the NSPs from the FMD vaccine antigens. However, since this method leaves residual NSPs, we established a method to remove NSPs by chloroform treatment. The NSPs were not detected in treatment with more than 2% chloroform in the FMD virus (FMDV) culture supernatant. It was verified that the chloroform treated FMD vaccine eliminated NSPs by animal immunization. For industrial application, the mixing volume of the FMDV culture supernatant and chloroform was scaled-up. In a 2 liter bioreactor, 2% of chloroform and 2,000rpm of impeller speed were established as an optimal mixing condition. Using an electronic mixer, 2% of chloroform and 350rpm of agitator speed were established in a volume of 20 liters.In conclusion, a method for removing NSPs with minimum concentration of chloroform was developed. Furthermore, by scaling up this, it is expected that FMD vaccine manufacturers could be able to easily produce high-purity FMD vaccines.

<P><B>Background:</B></P><P>In this study, we presented a theoretical model to measure aging rate in OECD countries, quantitatively measuring the effect of aging rate on disease patterns in each country and explaining how these effects were obtained. The purpose of this study was to investigate how disease burden varies according to the level of medical infrastructure and changes in aging index using OECD aging data and WHO disease burden data.</P><P><B>Methods:</B></P><P>This study used OECD Health data and global burden of disease data from the WHO in 2000 and 2012. We applied a difference-in-differences (DID) model was used to analyze effects of aging.</P><P><B>Results:</B></P><P>Disease burdens increased over time, especially in the aging population of middle-aged. In the case of loss of life due to premature death, the number of middle-aged and older population was increased significantly. When we examined the econometric model after controlling related factors, there was a significant increase in loss of life due to illness and premature death. On the other hand, the group of piles at the aging level had a significant positive effect on Years of Life Lost (YLL). Although the interaction effect as an important variable showing double difference effect of aging did not affect Disability adjusted Life Year (DALY), it showed a significant positive effect on YLL.</P><P><B>Conclusion:</B></P><P>Loss of life due to death of the elderly was relatively higher than that of the elderly. Therefore, the impact of population aging on medical resources and medical expenditures in the future should consider population structure changes, disease burden by age group, and interactions of these two incremental factors.</P>

The foodborne illness is the important public health concerns, and the livestock feces are known to be one of the major reservoirs of foodborne pathogens. Also, it was reported that 45.5% of foodborne illness outbreaks have been associated with the animal products contaminated with the livestock feces. In addition, it has been known that the persistence of a pathogens depends on many potential virulent factors including the various virulent genes. Therefore, the first step to understanding the public health risk of livestock feces is to identify and describe microbial communities and potential virulent genes that contribute to bacterial pathogenicity. We used the whole metagenome shotgun sequencing to evaluate the prevalence of foodborne pathogens and to characterize the virulence associated genes in pig and chicken feces. Our data showed that the relative abundance of potential foodborne pathogens, such as Bacillus cereus was higher in chickens than pigs at the species level while the relative abundance of foodborne pathogens including Campylobacter coli was only detected in pigs. Also, the microbial functional characteristics of livestock feces revealed that the gene families related to “Biofilm formation and quorum sensing” were highly enriched in pigs than chicken. Moreover, the variety of gene families associated with “Resistance to antibiotics and toxic compounds” were detected in both animals. These results will help us to prepare the scientific action plans to improve awareness and understanding of the public health risks of livestock feces.
