2015년말 사학연금제도의 법 개정이 이루어졌다. 그동안의 연금개혁이 주로 연금보험료 인상으로 이루어졌다면 이번 연금개혁은 연금지급률, 연금보험료률, 연금수급개시연령, 연금수급자에 대한 연금액 동결 등 다각적으로 이루어졌다. 국민연금과 동일한 수준의 가입자 내 소득재분배가 이루어졌다는 점도 특이하다. 본 논문은 사학연금법 개정의 재정효과와 후생효과를 분석하여 사학연금제도 개혁의 의미를 평가하고 정책과제를 도출하고 있다. 사학연금은 특수직역연금 중 유일하게 연기금이 아직 존재하는 제도로서 이번 연금개혁으로 국민연금에 가까운 재정안정화 효과를 거두었다는 점에서 큰 의의가 있다. 소득대체율과 연금수익비 등 후생적 측면에서의 후퇴에도 불구하고 제도의 안정성이 높아졌다는 점에서 의의가 크다. 이번 연금개혁으로 사학연금은 상당부분 국민연금제도와 유사하게 변동하였다는 점에서 국민연금과의 형평성도 제고되었다고 볼 수 있다. 2009년 연금개혁의 미비점을 보완하고 보다 완성도가 높은 개혁이 이루졌다고 볼 수 있다. 향후 국민연금제도의 재정안정화 추이에 맞추어 사학연금제도가 함께 부응해 나간다면 사학연금은 보다 재정적으로도 건전한 제도로 자리잡을 수 있을 것으로 판단된다.

This Study has been carried out to develop a method of analysis of 8 permitted synthetic food colors [including Brilliant Blue FCF(B1), Indigocarmine (B2), Fast green FCF(G3), Amaranth (R2), Erythrosine (R3), Allura red (R40), Tartrazine (Y4), Sunset Yellow FCF (Y5)] in Korean foods by HPLC. After adjusting to 0.5% HCl, each of the food colors extracted was eluted by Sep-pak $C_{18}$ cartridge. Eluates were then determined by high performance liquid chromatograph with a UV-VIS detector. Recoveries of the 8 synthetic food colors were found to be 81.2-98.0% for soft drinks, 80.6-96.1% for candy, 79.8-96.3% for chewing gum, 76.5-91.7% for cereals, 79.9-93.8% for ice cream and 78.6-94.7% for jelly, respectively. The detection limits were $0.05-0.1{\mu}g/g$.

Herbicides were classified by two-dimensional ordination analysis based on the weed flora which was not controlled by application of a particular herbicide. The number of herbicide group was varied depending upon the weed community type and the experiment site. The technique of the two-dimensional ordination analysis gave more comprehensive informations about selecting of herbicides for increasing the herbicidal efficacy, for increasing the weed spectrum and for reducing the herbicide cost by mixing of herbicides. The two-dimensional ordination analysis could be used not only herbicide classification and selecting effective herbicide or herbicide combination but also can be used for the evaluation of systematic application of herbicides.

The objectives of this study, an analysis of the morphological characteristics among six provenances of a rare Rhododendron micranthum could be used for the conservation of gene resources and could provide information on superior trees selection. The following results were obtained. Approximately Mt.worak region showed larger values at petal character. On the other hand, Bonghwa region showed smaller values at petal character. Yeonha-ri region showed larger values at leaf character. On the other hand, Bonghwa region showed smaller values at leaf character. The results of principal component analysis (PCA) for morphological characteristics showed that the first for principal components(PC's) explained 41.6% of the total variation. From th third PC explained 81.5% of the total variation. The first PC was correlated with those characteristics that were mainly related to the Petal length (PL), Leaf length (LL) width (LW), Stigma length (SL). The second PC was correlated with the Petiole length (PTW), Anther length (AL). The third PC was correlated with the Flower pedicel length (FPL), Filament length (FL). Therefore, these characteristics was important to analysis of the variation for morphological characteristics among provenances of Rhododendron micranthum. Cluster analysis using single linkage method based on morphological characteristics showed that six provenances of Rhododendron micranthum could be clustered into three groups. Group I is Jicdong-ri, Group II is Mt.worak and Yeonha-ri, and Group III is Taeback, Bonghwa, and Samcheok. These results corresponded well with that of principal component analysis.

The Total Pollutant Load Management System(TPLMS) in the Han River basin is being changed from a voluntary to a mandatory system. Accordingly, this study suggests directions and priorities for research that can support implementation of TPLMS through an objective approach that deploys gap analysis and analytic hierarchy processes (AHP). Gap analysis indicated that TPLMS in Korea is still focused on compliance with regulations, and that implementation of TPLMS is still in its early stage. Improvements are thus needed in flexibility and effectiveness, including introduction of emissions rights trading, and upgrading to a renewable emissions permit system. The AHP study indicated that R&D will need to proceed in parallel in multiple areas to improve systems and resolve scientific uncertainties. Balanced R&D will be needed in both the institutional and technical groups. Subgroup analysis indicated that developing a reasonable process to establish water quality management targets is of the highest priority in the institutional group. In the technical group, higher priority will need to be given to improving model reliability and developing innovative pollution load reduction technologies.

This study confirms that there is a correlation between managers' incentive-compensation system(introduction of the compensation committee) and corporate governance mechanisms (ownership structure, proportion of outside directors, debt ratio, competitive strength), and analyzes whether firm value is affected by corporate governance mechanisms. The purpose of this paper are empirically tested using 318 firm-year data listed on the KRX from 2001 to 2010 and 2SLS(two-stage least square method) were used for the analysis of the hypotheses. The results of empirical tests are as follows. Firstly, there is no correlation between introduction of the compensation committee and corporate governance mechanisms. In addition, the results show that there is a causal relationship between some variables. Secondly, results from the analysis of the impact of corporate governance mechanisms on firm value, only introduction of the compensation committee and foreign investors ownership were analyzed as a positive impact on the firm value. This result means that most domestic firm don't actively used for managers' incentive-compensation system as a useful control device for improving corporate governance.

The purpose of this study was to examine the effects of the employment policy for persons with disabilities on their employment rates. The subjects were 10 OECD counties of which policies are based on quotas or the prohibition of discrimination. The time-series data for the analysis were collected for 12 years from 2000 to 2011. A Panel-Corrected Standard Error(PCSE) analysis was conducted for the time-series cross-sectional data of this study. As a result, unemployment rates, proportions of persons with disabilities, and public expenditures on disability and sickness benefits(in % GDP) were statistically significant among control variables, while the coverages of discrimination prohibition and the types of delivery systems of vocational rehabilitation for persons with disabilities among the employment policy variables. The wider the coverages of discrimination prohibition are, the higher the employment rates of the disabled are. In addition, the employment rates of the disabled are higher in countries with specialized delivery systems for vocational rehabilitation than in countries with general delivery systems for vocational rehabilitation.

There are several types of petroleum products used for the fuel oil, according to their respective quality standards, grades and usage. Depending on the degree of oil tax rate by country, even the same petroleum products will have price gap. The illegal mixing of cheap petroleum products, which are subject to the lower tax rate, with relatively expensive transportation fuel causes problems such as tax evasion, environmental pollution and vehicle breakdown. In order to prevent illicit production and mixing of these different petroleum products, a small amount of markers are legally added to specific petroleum products. In Korea, markers are introduced and used to prevent illegal activity that kerosene used as fuel for house and commercial boiler are mixed with automotive diesel fuels, and marker contents are analyzed to use UV-Vis spectrophotometer and high performance liquid chromatography (HPLC). In this study, we have developed a method to qualitatively and quantitatively determine the marker added to petroleum products by gas chromatography-mass spectrometry (GC-MS) without adding developing reagent or sample pre-treatments.
