Recently, increased caffeine intake has led to an increase in caffeine addiction and withdrawal symptoms. Coffee is surreptitiously consumed in as an additive to milk and caramel. There are few studies on how coffee affects the health of modern people. The purpose of this study is to determine the efficacy and side effects of coffee by awareness of coffee consumption patterns among college students, who are the principal consumers. A survey was conducted from May 11 to 17, 2015 and 302 questionnaires were analyzed. The respondents were 140 men (46.4%) and 162 women (53.6%). In terms of coffee additives, 151 (50.0%) respondents chose 'americano' and 111 (36.8%) 'variation'. The frequency of coffee intake and sleep time for college students was negatively correlated, with the correlation coefficient of -0.145 and significance probability of 0.019. The group that was 'positively' aware of the principal ingredients of coffee had a higher level of academic training than those with 'negative' awareness (p=0.000). Women recognized a larger number of side effects than men: 1.99 and 1.36, respectively, on average (p=0.001). 'Time for consumption' had statistically significant effects on the side effects of coffee consumption: consumption before/after lunch, before/after supper and before going to bed led to 0.4 times (p=0.048) and 0.3 times (p=0.023) more side effects, respectively, than consuming coffee after getting up and before/ after breakfast. Excessive caffeine intake through coffee led to limited sleep time and poorer learning concentration. The guidelines for proper coffee consumption should be created to help students consume coffee properly so that it will not affect sleep, learning concentration or adversely affect health.

Among mammals, the mouse is one of the most commonly used experimental animals in the fields of genetic analyses, developmental studies, behavioral studies and toxicology studies etc. Mice are popular to biologist for several advantages they have. First, they belong to one of the smallest mammals, adult weights of which are as light as in the range of 25-40 g and are relatively docile, making their manipulation and handling easy. Second, they have a short lifespan, meaning that they could be chosen as a good tool in mammalian genetics. Third, females drop prolifically with an average of 5-10 pups per litter and enter a new postpartum estrus immediately. Finally, One of the unique advantages to work with mice, rather than other experimental organisms, is the availability of standard strains such as C57BL/6, BALB/c, and many others. With the use of the same standard inbred stram, it is possible to eliminate genetic variability as a complicating factor in comparing results obtained from expenments performed in Japan, Canada, Germany, or any other country in the world.

The purpose of this study was to determine the effects of awareness and knowledge of the efficacy of carbonated water on consumption patterns and satisfaction for college students, who are the principal consumers of carbonated water. A survey was conducted with 502 college students in the Metropolitan area from May 13 to 18, 2015 and 455 questionnaires were analyzed. As for the differences in awareness and knowledge of the efficacy of carbonated water according to gender, females (14.60 and 0.76) had better awareness and knowledge than males (13.40 and 0.58) (p=0.000 and p=0.036). The more positive the awareness of carbonated water, the greater the knowledge (p=0.000); the greater the knowledge of carbonated water, the higher level of consumption satisfaction (p=0.006). The odds ratio of awareness for carbonated water was 11.98; that is, positive awareness led to higher levels of satisfaction than negative awareness (p=0.003). Since awareness of the efficacy of carbonated water was found to affect carbonated water drinking and satisfaction, it is necessary to provide correct information about the efficacy of carbonated water.

Due to the deterioration of water supply network and the deficiency of raw water, the water utility of local governments have performed various projects to improve their revenue water ratio. However, it is very difficult to estimate the cost for maintaining the revenue water ratio at higher level after completing the project, because local governments have different conditions affecting the operating and maintenance cost of water supply network. The purpose of this study is to present a procedure to estimate the operating and maintenance cost required to maintain the target revenue water ratio of the water supply network. For this purpose, we estimated the cost used only for operation and maintenance of water supply network of 164 local governments with the aid of K-Mean Clustering Analysis and the data from 40 representative local governments. Then, the regression analysis was performed to find relationship between revenue water ratio and the operating and maintenance cost with two different data sets generated by two classification methods; the first method classifies the local governments by means of k-means clustering, and the other classifies the local governments according to the index standardized by the operating and maintenance cost per unit length of water mains per revenue water ratio. The results shows that the method based on the index standardized by the cost and revenue water ratio of each government produces more reliable results for finding regression equations between revenue water ratio and the operating and maintenance cost only for water supply network. The estimated regression equations for each group can be used to estimate the cost required to keep the target revenue water ratio of the local government.

This study reports a surfactant-enhanced in-situ remediation treatment at a test site which is located in a hilly terrain. The leakage oils from a storage tank situated on the top of the hill contaminated soils and groundwater in the lower elevation. Sixteen vertical injection wells (11 m deep) were installed at the top of the hill to introduce 0.1-0.5 vol.% of non-ionic Tween-80 surfactant. The contaminated area that required remediation treatment was about $1,650\;m^2$. Two cycles of injecting surfactant solution followed by water were repeated over approximately 7.5 months: first cycle with 0.5 month of surfactant injection followed by 3 months of water injection, and second cycle with 1 month of surfactant followed by 3 months of water injection. The seasonal fluctuation in groundwater table was also considered in the selection of periods for surfactant and water injection. The results showed that the initial Total Petroleum Hydrocarbon (TPH) concentration of 1,041 mg/kg (maximum 3,605 mg/kg) was reduced significantly down to 76.6 mg/kg in average. After 2nd surfactant injection process finished, average TPH concentration of soils was reduced to 7.5% compared to initial concentration. Also, average BTEX concentration of soils was reduced to 10.8%. This resultes show that the surfactant enhanced in-situ remediation processes can be applicable to LNAPL contaminated site in field scale.
