Attempts were made to increase an efficiency of soil contamination investigation systems(SCISs) including Soil Contamination Fact-Finding Investigation Sites and Special Soil Contamination Management Facility Sites in Korea. In order to increase low efficiencies resulting from inappropriate SCISs, possible policy suggestions are driven based on the results from problem findings of Korean policy and comparisons of policies in industrialized countries including United States, United Kingdom, Germany, the Netherlands and Japan. First, functions of Soil Environment Conservation Act(SECA) on liability should be updated and reinforced to initiate a soil contamination investigation process for stakeholders including an owner(s) or a responsible party(ies) of the potentially soil contamination sites positively. Second, appropriate SCISs should be emerged for implementing the Soil Contamination Fact-Finding Investigation Sites and Special Soil Contamination Management Facility Sites properly. Stakeholders for the potentially contaminated sites should easily access and raise the soil contamination issues, and soil contamination investigation implemented by liable and profit environment (consulting) companies should be encouraged. Third, the soil contamination reporting system of SECA needs to change legally responsible. Further more, public announcement system showing soil quality of a site which exceeds a certain scale would be considerable. Fourth, liable environment (consulting) companies should legally execute Soil Environment Assessment of SECA.

Long-term measurement of total mercury (TM) and dissolved gaseous mercury (DGM) were performed in Yangsuri marsh. Average TM and DGM concentrations were $2.0{\pm}2.0$ ng/L and $15.0{\pm}2.8$ pg/L, respectively, indicating that only 2.6% of TM existed as the form of DGM in Yangsuri marsh. While TM did not show the seasonal variation a statistically high DGM concentration was observed in warm season, indicating that DGM was effectively produced by strong solar radiation and high water temperature. There was no relationship between TM and DGM concentrations in Yangsuri marsh, as observed in other studies. DGM in Yangsuri marsh was supersaturated for most of sampling period; therefore, one can conclude that $Hg^0$ in water surface can readily volatilize to the atmosphere.

Those studies in the field of Management Information Systems and the Success Model of the DeLone and McLean's Information Systems suggest that some factors related to information systems should be developed and operated to affect the performance of the user's personal and companies through the introduction and use of corporate information systems. The purpose of this study is put on searching for some factors which impact on user satisfaction about the customer information management systems of call center. We did conduct on a survey of 539 people who are working as a call center counseling employees as setting up a structural equation model which reflects previous research on working environment and job satisfaction, and modified DeLone and McLean's information system success model. The results of this study are as follows. First, seven of the eleven hypotheses that three quality of the information systems might be affecting working environment, job satisfaction, user satisfaction were adopted Second, we confirmed that the working environment works as a the partial mediation and the quality of services works as a fully mediation between system/information quality and users' satisfaction. The implications of this study are that it is necessary not only to make a good working environment but also to keep improving it in order to boost the operational performance of information systems in the future.

The purpose of this research is to contemplate chronological changes of Korean actress facial image and fashion from 1960s to 1990s and to identify Korean women's ideal beauty reflected through the times. Adjectives describing representative actresses of each studied decade were collected from major newspapers and magazines. Korean women's ideal beauty was divided into 4 sub-types such as youthful, pure, sophisticate, and sexy images. As a result of analyzing actress facial image and fashion, youthful and pure beauties were found consistently over the studied periods. Representative characteristics of sophisticate and sexy beauties have been changed over the studied periods which were influenced by socio-cultural environment factors. The result of this research can provide meaningful sources for historical drama, celebrity marketing strategy planning, and personal image consulting.

The removal of organic carbon and nutrients (i.e. N and P) from wastewater is essential for the protection of the water environment. Especially, nitrogen compounds cause eutrophication in the water environment, resulting in bad water quality. Conventional nitrogen removal systems require high aeration costs and additional organic carbon. Microbial electrochemical system (MES) is a sustainable environmental system that treats wastewater and produces energy or valuable chemicals by using microbial electrochemical reaction. Innovative and cost-effective nitrogen removal is feasible by using MESs and increasing attention has been given to the MES development. In this review, recent trends of MESs for nitrogen removal and their mechanism were conclusively reviewed and future research outlooks were also introduced.

This study modifies the present total maximum daily load (TMDL) system of Ministry of Environment and applies to the Anyangcheon watershed. Hydrologic Simulation Program-FORTRAN (HSPF) model is used to simulate both runoff and non-point source pollution, simultaneously, instead of QUAL2E. The drought flow (355th daily flow) is proposed for the target water quantity since it is easier to satisfy low flow (275th daily flow) for the target water quality than drought flow. The increase of discharge is more than the increase of pollutant load except for the period under low flow. The measured unit loads for non-point source are used to consider the regional runoff characteristics. The measured water quantity and quality data are used since the ministry of environment supports only water quality. This analysis results show some reasons for the improvement of the present TMDL system of Korea.

The purpose of this study falls into the development of national skill system in environmental field. The jobs were classified by the commonly used terms in the field. Consequently there are three large groups, twelve middle groups which again narrow down to smaller jobs according to the relevant characteristics of each job in the group, and forty one jobs in total in the area. Six levels were identified for the definition of job level and the development of performance level by reflecting job levels by expertise. Under the consideration of the unique characteristics of the environment field, job levels were also defined in accordance with each area such as 'environment plan and assessment', 'measurement and analysis of environment', 'environment management', 'environment design and construction', 'environment health management', 'environment resources management', 'environment management and consulting', and 'environment education'. Based on these classification, the definitions of jobs and the standards of performances by jobs and levels were resulted in through a consultation consisting of experts in the environment industry and academy.

In this study, a functional inorganic insulation as TiO₂ and inorganic wet fly ash were used to evaluate the physical performance and thermal environment of an exterior finish that can improve the thermal environment of a building. The performance evaluation of the finish was based on the KS F 4715 thin coating material and the thermal environment. When TiO₂ was added, the physical performance was lowered at 10% or more, and the inorganic wet-treated fly ash increased the physical performance by 10%. In the thermal environmental evaluation, the surface temperature reduction effect of the inorganic wet-treated fly ash was low, but when used in combination with TiO₂, it was effective to reduce the surface temperature and the internal temperature. As a result, the optimum combination of TiO₂ and inorganic wet-treated fly ash for thermal environment control was found to be optimal when 5% of each mixture was used.

The aim of this study was to establish research hypotheses and conduct empirical analysis to clarify the relationship between self-leadership, self-efficacy, job satisfaction, and job performance of researchers in the energy and environment fields. Data were extracted from questionnaires returned by 165 researchers in the field of energy environment among 200 questionnaires collected for approximately three weeks. The reliability, frequency, descriptive statistics, correlation analysis, multiple regression analysis, and sobel-test were examined using the SPSS 22.0 statistical program. The self-leadership of the researcher has a positive (+) effect on self-efficacy, job satisfaction, and job performance, and the researcher's self-efficacy has a positive (+) influence on both job satisfaction and job performance. In addition, the self-efficacy and job satisfaction mediated the relationship between self-leadership, and job performance. Therefore, to improve the job performance of the researchers, it is important to establish a system for the human resource management of the affiliated institutions and revitalize the education for the self-leadership and self-efficacy improvement. In addition, it is necessary to provide an appropriate compensation system to satisfy the researchers' enjoyment, satisfaction and trust in their jobs. In particular, because self-efficacy is a very important factor for job performance, it is important to prepare an institutional strategy for strengthening the self-efficacy of researchers.
