2004년 8월 고용허가제가 시작된 이후 2012년 7월에 숙련인력 계속 고용 및 불법체류 감소를 위한 목적으로 ‘성실근로자 재입국 취업 특례제도’를 실시하였다. 하지만 본연의 취지와는 다르게 재입국 외국인 근로자의 이직이 늘어가고 있다. 본 연구는 고용허가제 ‘성실근로자 재입국 취업 특례제도’로 들어 온 외국인 근로자의 이직의도에 영향을 미치는 주요 요인을 분석하여 정책의 개선 방안을 모색하기 위한 것이다. 이와 같은 목적을 달성하기 위해 본 연구는 선행연구에서 추출한 직무만족도, 직장상사와의 관계, 직장동료와의 관계, 근무환경을 요인으로 한 설문지를 사용하여 경기도에 머무르는 고용허가제를 배경으로 하는 E-9 체류자격자 중 ‘성실근로자 재입국 취업 특례제도’로 들어 온 외국인 근로자 즉 ‘성실근로자’ 대상으로 하였다. 자료 분석은 이직의도에 영향력이 높은 변인을 알아보기 위해 다중회귀분석을 실시하였다. 그 결과 성실근로자의 이직의도에는 직무만족도와 직장상사와의 관계가 영향을 미치는 것으로 나타났으며 직무만족도가 더 높은 영향을 미치는 것으로 나타났다. 연구결과에 근거하여 외국인 성실근로자의 이직을 예방에 고려해야 할 정책과 실천의 방안을 논의하였다. Since the start of the Employment Permit System in August 2004, in July 2012, the Ministry of Labor and Social Security carried out a ‘Employment Exemption for Sincere Workers’ program for the purpose of reducing the number of skilled workers and illegal residents. However, unlike the original intention, the number of foreign workers migrating to re-entry is increasing. The purpose of this study is to analyze the major factors influencing the turnover intention of foreign workers entering the Employment Permit System, The purpose of this study was to investigate the relationship between job satisfaction, relationship with workplace supervisor, relationship with work colleagues, and work environment, 9 foreign workers who came into the ‘exceptional employment system for re-entry of sincere workers’, ie, ‘sincere workers’. Data analysis was conducted with multiple regression analysis to see variables that had a strong influence on turnover intention. As a result, the relationship between job satisfaction and job boss affects the turnover intention of sincere workers, and job satisfaction has a higher effect on turnover intention. Based on the results of the study, we discussed policies and practices that should be taken into consideration in the prevention of separation of foreign workers.

Petroleum is the most consumed energy source in Korea with a usage rate of 38.7% among the available primary energy sources. The price of liquid petroleum products in Korea includes taxes such as transportation·environment·energy tax. Thus, illegal production and distribution of liquid petroleum is widespread because of its huge price difference from that of the normal product and its tax-free nature. Generally, the illegal petroleum product is produced by mixing liquid petroleum with other similar petroleum alternatives. The two kinds of gasoline, common gasoline and premium gasoline, are being distributed in Korea. The premium gasoline is often adulterated with cheaper common gasoline that lowers the octane number of gasoline. It is possible to distinguish them with their color difference, green and yellow for different grade gasoline. However, when small volume of common gasoline is added to premium gasoline, it is difficult to determine whether premium gasoline contained common grade or not. In this study, we inspect gasoline, which is illegally produced by mixing common gasoline to premium gasoline. When the ratio of mixing common gasoline is increased, premium gasoline shows decreasing absorbance at 600 nm and 650 nm under UV-Vis spectrometer. Moreover, the detected intensity (mV·s) of green dye in high performance liquid chromatography (HPLC) was decreased by common gasoline under 0.99 correlation value. The more the common gasoline is mixed, the more olefin and naphthene are detected by gas chromatography. In addition, trimethyl pentane as octane improver, paraffin and toluene are decreased by common gasoline mixing. The findings of this study suggests that illegal petroleum can be identified by analysis of components and simulated samples.

It rains heavily, such as long rain and typhoons, during a typical rainy season in Korea. In this season, several fuel contamination accidents by water and vehicular problems caused by water contaminated fuel occur. Many research groups have studied the effects of water contaminated fuel on vehicles and environment. However the characteristics of water contaminated fuel have not been studied. In this study, we prepared diesel samples with a constant ratio of water (0~30 volume %) using an emulsifier. Then, we analyzed these diesel samples for their representative fuel properties. In the analytical results, diesel with 30% water showed an increase in fuel properties such as density (823→883 ㎏/㎥), kinematic viscosity (2.601→6.345 ㎟/s), flash point (47→56℃), pour point (-22→2℃), CFPP (cold filter plugging point) (-17→20℃) and copper corrosion number (1a→2a). The low temperature characteristics, such as low pour point and CFPP, blocks the fuel filter in the cold season. In addition, water contaminated diesel decreases lubricity (190→410 ㎛) under high frequency reciprocating rig (HFRR) and derived cetane number (54.81→34.25). The low lubricity of fuel causes vehicle problem such as pump and injector damage owing to severe friction. In addition, the low cetane diesel fuel increases exhaust gases such as NOx and particulate matters (PM) owing to incomplete combustion. This study can be used to identify the problems caused by water contamination to vehicle and fuel facilities.
