This study conducts quantitative analysis with the use of GIS of characteristics of Buddhism relics spatial locations such as Buddhist temple sites. With the intention of analysis of the generally known Buddhist temple site locations from spatial side, following the Buddhism relics sites state, the present conditions of Buddhist temple sites was analyzed from the spatial point of view. The results of the present study are that, comparing with general location analysis, different characteristics of competitive strength which maintains Buddhist temple sites functioning until now are showing. In case of such cities as Chuncheon and Wonju, Buddhist temples exist in the areas of high locational competitiveness, and most of them were located in the areas which with relatively poor environment. On the other hand, comparing with Samchuk city case, the location environment of Buddhist temples there turned out to be excellent. Such results show that we can discover the special characteristics of Buddhism which holds the entire history for the space called the Korean Peninsula.

In order to assess risk of high temperature damages about corn during reproduction stages in the future, we carried out analysis of climate change scenarios RCP (Representative Concentration Pathway) 4.5 and RCP8.5 distributed by KMA (Korea Meteorological Administration) in 2012. We established two indexes such as average of annual risk days of high temperature damage which express frequency and strengthen index of high temperature damage. As results of producing maps for 157 cities and counties about average of annual risk days of high temperature damage during total periods of scenarios, the risk of high temperature in RCP8.5 was evaluated to increase at all over nation except inland area of Gangwon province, while RCP4.5 showed similar to present, or little higher. The maps of annual risk days of high temperature damage with 10 years interval in RCP8.5 prospected that the risk for damaging corn growth would increase rapidly from 2030's. The largest risk of high temperature damage in the future of RCP8.5 was analyzed at Changnyeong county located east-south inland area in Kyeongnam province, while the smallest of risk counties were Pyeongchang, Taebaek, Inje, and Jeongseon. The prospect at 12 counties which is large to produce corn at present and contains large plains have been showed that there will be only a little increase of risk of high temperature at Goesan, Yangpyeong, Hongcheon, Seosan, and Mooju until 2060's. But considering strengthen index of high temperature damage, most regions analyzed would be prospected to increase rapidly after 2030's. To cope with high temperature damage of corn in the future, we should develop various practical technologies including breeding adapted varieties and controlling cultivation periods.

The quantitative analysis on the pollutants loads (PL) has hardly been carried out and calibration-verification process of the water quality modeling has been conducted under the restricted condition because the observed PL data are not sufficient. In this study, the PLs were measured at the 22 streams and the effluents site in the Masan-Changwon watersheds. The release rates from sediment were also measured at the three points in the Bay. The PLs from the Masan and Changwon cities and from multi-port diffuser(effluents discharge) amount to 80∼90% and 20∼25% of the PL in Chinhae-Masan Bay, respectively. As the amounts of the sediment released pollutants are the same order of the PLs form the watersheds, the pollutants released from the sediment is one of the main factors that might cause the seasonal variation of the water quality, which is degraded in summer and relatively good in winter.

Google Trends is a useful tool not only for setting search periods, but also for providing search volume to specific countries, regions, and cities. Extant research showed that the big data from Google Trends could be used for an on-line market analysis of opinion sensitive products instead of an on-site survey. This study investigated the market share of tumor necrosis factor-alpha (TNF-α) inhibitor, which is in a great demand pharmaceutical product, based on big data analysis provided by Google Trends. In this case study, the consumer interest data from Google Trends were compared to the actual product sales of Top 3 TNF-α inhibitors (Enbrel, Remicade, and Humira). A correlation analysis and relative gap were analyzed by statistical analysis between sales-based market share and interest-based market share. Besides, in the country-specific analysis, three major countries (USA, Germany, and France) were selected for market share analysis for Top 3 TNF-α inhibitors. As a result, significant correlation and similarity were identified by data analysis. In the case of Remicade's biosimilars, the consumer interest in two biosimilar products (Inflectra and Renflexis) increased after the FDA approval. The analytical data showed that Google Trends is a powerful tool for market share estimation for biosimilars. This study is the first investigation in market share analysis for pharmaceutical products using Google Trends big data, and it shows that global and regional market share analysis and estimation are applicable for the interest-sensitive products.

The uniform hazard spectra for seven major cities in Korea, Seoul, Daejeon, Daegu, Busan, Gwangju, Ulsan, and Inchon are suggested. Probabilistic seismic hazard analyses were performed using the attenuation equations derived from seismology research in Korea since 2000 and the seismotectonic models selected by expert assessment. For the estimation of the uniform hazard spectra, the seismic hazard curves for several frequencies and PGAs were calculated by using the spectral attenuation equations. The seismic hazards (annual exceedance probability) calculated for the 7 metropolises ranged from about $1.4305{\times}0^{-4}/yr$ to $1.7523{\times}10^{-4}/yr$ and averaged out at about $1.5902{\times}10^{-4}/yr$ with a log standard deviation of about 0.085 at 0.2 g. The uniform hazard spectra with recurrence intervals of 500, 1000, and 2500 years estimated by using the calculated mean seismic hazard on the frequencies presented peak values at 10.0 Hz, and the log standard deviations of the difference between metropolises ranged from about 0.013 to 0.209. In view of the insignificant difference between the estimated uniform hazard spectra obtained for the considered metropolises, the mean uniform hazard spectrum was estimated. This mean uniform hazard spectrum is expected to be used as input seismic response spectrum for rock sites in Korea.

This is the study to find out the differences between the mandated reporters who reported child abuse and who did not report and to know which factors affect the reporting behavior The researcher sent questioners to 595 doctors, teachers, nurses and social workers in 3 different cities as a sample. 477 people responded to questioner and only 116 people who said that they have found out abused child during the last year were used for analysis of this research. Among 116 people, only 35.4% reported child abuse. There were significant differences between two groups, groups that reported child abuse and groups that did not report, in attitude about Abuse, the experience of child abuse training and knowledge about abuse. However, the result of Logistic regression showed that reporting behavior are significantly affected by occupation, experience of child abuse training and severity of abuse.

Purpose: The purpose of this study was to identify the relationship between self-esteem and sexual attitude in healthcare college students, and also to provide a basis for sexual health education programs to help establish healthy sexual attitudes. Methods: A survey was conducted with 218 unmarried students attending the healthcare colleges in B and U cities. Data were collected from October 15 to November 10, 2015 and analyzed using Stepwise multiple regression with SPSS PASW 18.0. Results: Mean score for self-esteem was $3.23{\pm}0.46$ out of 5 and sexual attitude $2.64{\pm}0.54$ out of 5. Self-esteem and sexual attitude had a negative correlation (r=-.169, p=.012). Among sub-variables of sexual attitude, negative correlations were found between self-esteem and premarital chastity (r=-.207, p=.002), and between self-esteem and homosexual attitudes (r=-.167, p=.013). There were statistically significant differences in sexual attitude according to perceived intimacy with mother (${\beta}$=-.228, p<.001), year in college (${\beta}$=.135, p=.047), major (${\beta}$=.148, p=.023), religion (${\beta}$=-2.429, p=.016), and homosexual tendencies (${\beta}$=.139, p=.037). These factors explained 14.6% of the variance in sexual attitude. Conclusion: Findings demonstrate the importance of self-esteem for sexual attitudes. This finding should be used in the development of healthcare college students, promotion programs to enhance healthy sexual attitudes.

There have been many conflicts in Pyeongtaek-Dangjin Port among central government, metropolitan council, and cities over the jurisdiction of reclaimed port area, an international passenger terminal construction and a bridge between the port and Dangjin area. This study found out two causes for the conflicts in terms of governance. First, the current governance structure of Pyeongtaek-Dangjin port has high levels of conflict and disputes among stakeholder. Second, there is no leading agency which is responsible for the future development of the port. It is very important to decrease the possibility of conflict and to establish leading agency. Measures to decrease the likelihood of conflict include establishment of conflict resolution mechanism, the clarification of the facts and applicable law, mutual exchanges between stakeholder. Measures to establish a leading agency include the introduction of a single governance, establishment of Pyeongtaek-Dangjin Port Authority, central-local combined governance, and empowering PA to do all port management.

There have been few researches on the factors affecting forest recreation demand and demand for and value of forest recreation in Korea. This study has three main objectives as follows; First, to introduce the nature of recreation demand, the factors affecting forest recreation demand, and the methods of measuring demand for and benefits from forest recreation by reviewing related literatures. Secondly, to investigate the visitors' characteristics, patterns of recreation activities, and their attitudes for the recreation environments at the Deogyu National Park through interviewing them with the questionaire. Thirdly, to estimate the demand for and benefits of forest recreation at the National Park by Travel Cost Method. The survey was dealt by three trained interviewers at the enterance of the park for 5 days from September 26 to October 10, 1982. The 430 respondents were sampled randomly among 9,391 visitors with 4.6% of sampling rate. As the results, the study revealed that most of visitors to Deogyu National Park were from urban areas and belonged to the intermediate-upper income classes, and that most of them traveled more than 250 km or 4 hours to the site from their origins. And more respondents answered that the recreation environments of the cite were more or less better than other recreation areas. From the date of travel distances and participation rates of 13 cities or counties, the demand schedule of forest recreation at the National Park was established. The estimated equation of total experience demand curve is; Log $VR_i$ 2.6353 – 1.021 Log $D_i$ $R^2=0.9451$ where, $VR_i$ $(%\times1000)$ = Participation rate of the ith origin $D_i$ (km) = Travel distance from the ith origin From the total experience demand curve, the demand curve of recreation resources was built by adding travel cost in distance (km). The regression equation of the recreation resources at the Nation park is; Log V = 4.0304 – 0.8167 Log D $R^2=0.9060$ From the demand schedule of recreation resources, the recreational bendfits of Deogyu National Park was estimated. The estimated bendfits to a visitor from the forest is equivalent to the travel cost of 2,372 km. The study also found out that the demand for recreation resources was less elastic than the demand for the total recreation experience at the Deogyu National Park.
