This study was carried out to elucidate the preliminary ecosystem of the heterotrophic bacterial flora in Kunsan Bay located in western costal area of Korea. Samples were collected at 5 sampling stations. Among 123 bacterial isolates, 9 genera of bacteria were appeared as follows; Vibrio spp.(44 isolates/35.7%), Pseudomonas spp.(42 isolates/34.1%), Aeromonas spp.(11 isolates/8.9%), Moraxella spp.(9 isolates/7.3%), Enterobacteria spp.(6 isolates/4.8%), Bordetella spp.(3 isolates/2.4%), Alkaligenesis spp.(3 isolates/2.4%), Flavobacterium spp.(2 isolates/1.6%), and Staphylococcus spp.(3 isolates/2.4%) respectively. Total viable heterotrophic bacteria was ranged from $5{\times}10^3$ to $1{\times}10^5$ CFU/ml and the most abundant viable counts of bacterial population were showed at the stations 2 and 3. This result indicates that the coastal area around Kunsan bay is getting to contaminate far more by municipal wastewaters and industrial byproducts. and so the outbreak of the bacterial diseases will be increased in fish farms.

This study was the secondary analysis using the Korea National Health and Nutrition Examination Survey of 2012 and purpose was to investigate the effects of menopause on the metabolic syndrome(MetS) in Korean women. In raw data, total 2,746 women aged ${\geq}19$ years and provided the correct data about menstruation and menopause were analysed. The results were as follows: First, components of MetS were significantly different according to menopausal status. Second, the prevalence of MetS was 13.2% in premenopausal women and 42.7% in postmenopausal women. Third, the Odds ratio of postmenopausal women was 4.88(95% CI=3.888-6.126) compared with premenopausal women for MetS. As 5 years from 40 years increased, the Odds ratios of postmenopausal women were 3.15(95% Confidence Interval=1.862-5.331), 4.159(2.558-6.761), 5.971(3.955-9.016), 9.52(6.591-13.749) compared with premenopausal women for MetS, respectively. Based on the results, the intervention should be developed and provided for preventing and managing the MetS in postmenopausal women.

Shell necrosis, which is found in the juvenile stage of Haliotis discus hannai in th culture process, was examine in this study. In the necrosis shell, bacteria of rod type and a blue green algal species with heterocyst were observed. However, it appears to be caused by a boring blue green alga, Mastigocoleus sp., as based on SEM data. At the time of its infection, the shell was discolored from green into bright-grey, and then began to be brittle at the 4th to 6th breathing hole. After 60 days of culture, necrosis occurred in the breathing holes with many brown tiny colony, and continued to 3 years after culture. This shell necrosis was found in the tank culture system in land rather than in the cage culture system in sea, and greatly affected to the growth of Haliotis discus hannai, resulting in very small size of 16mm in 3 year old shell.

TCS Data imply characteristics of traffic conditions. However, there are outliers in TCS data, which can not represent the travel time of the pertinent section, if these outliers are not eliminated, travel time may be distorted owing to these outliers. Various travel time can be distributed under the same section and time because the variation of the travel time is increase as the section distance is increase, which make difficult to calculate the representative of travel time. Accordingly, it is important to grasp travel time characteristics in order to compute the representative of travel time using TCS Data. In this study, after analyzing the variation ratio of the travel time according to the link distance and the level of congestion, the outlier elimination model and the smoothing model for TCS data were proposed. The results show that the proposed model can be utilized for estimating a reliable travel time for a long-distance path in which there are a variation of travel times from the same departure time, the intervals are large and the change in the representative travel time is irregular for a short period.

The purpose of this study is to analyze the relationship between social development and life satisfaction according to horse riding participation degree of participants. In order to accomplish the purpose of this study, participants of the equestrian program were set as the population and the sample was extracted by the method of Stratified cluster random sampling. The input data were statistically processed according to the purpose of the study using the SPSS / AMOS 22.0 Version Statistical Program for Windows, and the results were as follows. The results of the analysis are as follows. First, there were some differences in demographic characteristics such as horse riding experience, social development, life satisfaction, and participation level. Second, there was a partial relationship between participation level and social development of participants. Particularly, the degree of participation in horse riding experience was related to the activity of social development. Third, the participation level of horse riding experience was analyzed as having no direct influence on participants' life satisfaction. Fourth, it was analyzed that the development of sociality due to participation in horse riding experiences did not directly affect life satisfaction. Fifth, participation in experience of horse riding, social development and life satisfaction were not causally related.
