This study surveyed how retirees' evaluation of starting food service business affects the effectiveness their new business and quality of life, based on personal factors such as entrepreneurship and business-starting capability and environmental factors by using questionnaires. Bootstrapping was carried out in order to find out factors affecting rapidly changing new business environments and retirees' initial intent to start a business so as to verify basic hypothesis about relation between retirees' evaluation of starting food service business (social, economic, and psychological effects) and the effectiveness of their new business and quality of life and confirm whether the effectiveness of the new business acts as a medium between the evaluation of starting food service business and quality of life. In addition, PLS-MGA was performed in order to verify whether the correlations among test factors can be varied according to the kind of job the target retirees had. Having examined the basic thesis, it was found that social and economic factors had significant positive effect on the effectiveness of the new business, and social and psychological factors had significant positive effect on the quality of life. Having analyzed whether the effectiveness of new business acted as a media between evaluation of starting food service business and quality of life, there was no significant effect as a medium. Having studied whether the kind of job of the retirees controlled or affected the relations among evaluation of starting food service business, effectiveness of new business and quality of life, the results were as follows: in the office job retiree group, the greater economic factor led to increase of effectiveness of new business, while social and psychological factors influenced the quality of life; In the physical labor group, the higher social factor resulted in higher effectiveness of new business, which showed significant positive effect on the quality of life. Having researched about which element is considered to be most important in starting food service business, the most important element was found to be dish/menu, followed by staff management, accounting management, business management, and service education. Having analyzed relation between accomplishment and important consideration for starting food service business, "managers with entrepreneurship," "appropriate distribution of time to prepare for starting business," and "operation of practical field education programs" showed higher importance compared to the degree of satisfaction, so it is needed to more concentrate on the above matters. This study intends to raise retirees' awareness of starting business and help them live better life based on the analysis results, and further suggest detailed mechanism and specific operations of factors affecting retirees' decision making on starting business, such that they can use the information as basic materials to make better choices that can lead to successful business.

This study evaluates life annuity plans based on two different types of measures : financial benefit and utility on consumption. The financial benefit is measured by Money's Worth (MW) ratio and return on annuity. For the measure of utility, an optimization problem is formulated with the objective of maximizing utility on consumption. To solve the optimization model, we use Dynamic Programming (DP) technique. The both types of measures are applied to cases of Korean pre-retirees at age 40 with different accumulation years of annuity (i.e. level of annuity asset at the age of retirement) and different timings of annuitization. Our results generally indicate that the utility based optimization model is superior to the financial measures in terms of providing a better evaluation of an annuity plan due to its capability to consider an individual's financial situation during his/her retirement period. Also, they suggest that the level of annuity asset is an important factor when an individual determines the optimal annuitization timing.

이 글은 신자유주의 사회개혁이 초래하는 문제점들을 밝혀내는 데 일차적인 목적이 있다. 이를 위해 이 글은 칠레의 연금민영화 사례를 근거로 하여 신자유주의가 제기하고 있는 주장들을 경험적으로 검토할 것이다. 특히 관심을 갖는 부분은 연금급여수준의 변화와 같은 연금개혁의 직접적인 결과들이다. 이러한 연구를 수행하는 이유는 칠레의 연금민영화 개혁에 대한 기존의 평가, 특히 신자유주의 진영의 평가가 지나치게 우호적이고 연금민영화의 긍정적인 측면들만을 부각하고 있기 때문이다. 일반적으로 어떤 사회정책이든지 밝은 면과 어두운 면을 모두 포함하고 있다는 점을 감안한다면 신자유주의 진영의 평가는 지나치게 단순한 것이라고 할 수 있다. 1981년 이후 최근까지의 관련자료 분석을 통해 얻은 이 글의 결론은 칠레에서는 민영화개혁 이후 연금의 급여수준이 낮아지고 있으며 연금제도의 소득재분배 효과가 작아졌다고 하는 것이다. 이와 같이 연금민영화로 인해서 사회구성원들 모두가 누릴 수 있는 복지의 수준이 낮아진다고 하는 점에서, 이 글은 연금을 비롯한 사회보장제도가 갖고 있는 문제들의 개선책은 민영화와 같은 극단적인 형태가 아니라 공적제도의 틀 속에서 찾아져야 한다고 시사한다.

본 연구는 기업에서 채용 전형 시 진행되는 인성시험 결과 데이터를 기반으로, 입사 3년 미만의 조기 퇴사자를 분석하였다. 예측 모형은 적합성 및 향후 활용성을 고려하여 제조(manufacture)직군과 R&D직군 2개 그룹으로 구분하여 분석하였으며, 독립변수 선택은 전진(stepwise)선택법에 따라 직군별로 유의미한 독립변수를 선택하였다. 예측 모형은 지도학습(supervised learning) 방법 중 로지스틱 회귀분석 알고리즘을 선택하였으며, 과잉적합(overfitting) 또는 과소적합(underfitting)을 방지하고자 교차 검증(cross validation)을 통해 예측 모형을 훈련시켰다. 혼동행렬(confusion matrix)을 통해 2개 그룹의 정확도(accuracy)를 확인하였으며, 조기 퇴직에 가장 영향을 많이 미치는 요인으로 제조직군에서는 '몰입', R&D직군에서는 '반사회성' 항목으로 확인되었다. 기존 퇴직 관련 연구는 설문 방식으로 데이터를 수집하고, 퇴직과 관련성이 높은 요인을 확인하는데 집중하였다면, 본 연구는 채용 전형 시 진행되는 인성 결과 분석을 통해 향후에도 지속 가능한 조기 퇴직 예측 모형을 제시했다는 면에서 의의를 갖는다.
