본 연구는 지적장애인의 고용을 지원하기 위한 정책을 수립하는데 근거가 될 수 있는 기초자료를 제공하는 연구로서 제2차 장애인고용패널조사에 참여한 지적장애인패널의 인구사회학적 특성 및 장애관련 특성, 지적장애인의 배경 변인과 취업 및 미취업과의 관계, 그리고 지적장애인의 취업 및 미취업을 예측하는 요인을 탐색하는 것이다. 본 연구에서는 한국장애인고용공단 고용개발원에서 조사한 「제2차 장애인고용패널조사(2009년)」원자료(raw data)를 이용하여 분석하였다. 본 연구에서 지적장애인의 경제활동에 영향을 미치는 요인을 분석하기 위하여 SPSS 18 버전을 이용하여 빈도분석, 교차분석, 다중회귀분석을 실시하였다. 취업에 미치는 영향력을 살펴본 연구결과는 경제활동 상태에 영향을 미치는 변수로 성별, 장애등급, 일상생활만족도가 유의미한 영향을 미쳤으며, 학력, 고용서비스 경험, 직업훈련/교육 경험, 자격증 보유, 건강상태, 주관적 사회경제적 지위는 유의미한 영향을 미치지 못한다고 나타났다. This study is to provide basic data which can be a base for establishing policy to support employment of Intellectual disabilities and to explore features of sociology of population and disability-related features of panels with intellectual disabilities who participated in the 2nd Research on Employment Panel for the Disabilities, the relationship between background variables of Intellectual disabilities and employment&unemployment, and the predictive factors for employment& unemployment of Intellectual disabilities. The present study is analyzed using raw data of ``the Second Panel Research on the Employment of the Disabled (2009)`` by EDI(Employment Development Institute) of KEAD(Korea Employment Agency for the Disabled). The frequency analysis, cross tabulation analysis and multiple regression analysis using SPSS 18.0 are initiated to analyze factors that affects to economic activities of Intellectual disabilities. As a result of analysis for effect on employment, gender, degree of disability, and satisfaction for daily living have significant effect as a variables that affect to the status of economic activities. And education, employment service experience, vocational training/education experience, with/without licenses, health condition and subjective socio-economic status have no significant effect.

Oysters are a highly consumed seafood throughout Korea, but they have a short shelf life because they support rapid microbial growth due to their of high moisture content and fragile muscle tissue. We examined natural food additives including lactic acid bacteria fermentation powder, rosemary extract, and lemon juice for their ability to preserve raw oyster Crassostrea gigas quality. Samples were stored at 4℃, and microbiological and physicochemical analyses were conducted. Among the natural additives tested, lemon juice was the most effective. Lemon juice was thus applied at different concentrations (50-300 ppm) to quantitatively assess its effect on total viable cell count, pH, glycogen, soluble protein, and turbidity. 200 ppm was confirmed to be optimal, and is projected to extend shelf life by 2 days compared to the control group.
