본 연구는 사학연금의 장기적 재정건전성을 확보하기 위한 재정추계 및 정책평가 방법에 관하여 논의한다. 먼저 재정안정화 시나리오의 설정에 있어서 기간간 예산제약식을 이용하여 장기적으로 균제상태(steady state)를 달성할 수 있는 납부율 및 급여율의 선정이 어떻게 이루어질 수 있는지 살펴본다. 또한 재정추계에 있어서 정책 변화에 따라 개인들의 행동 패턴이 달라질 가능성이 있음을 강조하고, 조기퇴직 결정에 관한 캘리브레이션을 통해 재정추계에서 내생성에 대한 고려가 어떻게 이루어질 수 있는지 예시한다. 마지막으로 힉스 보상의 개념에 기초하여 안정화 정책에 대한 평가가 연금 재정지표에 미치는 효과만이 아니라 가입자 / 수급자의 후생에 미치는 영향까지 같이 고려하여 이루어질 필요가 있음을 설명한다.

This study examined the aging of people with severe disabilities experiencing relative alienation and deprivation in an aging society to find ways to make them happy and economically stable. This study identified the determinants of economic preparation for aging among people with severe disabilities using the ecosystem perspective. For this study, data were drawn from Panel Survey of Employment for the Disabled (PSED). A total of 950 samples were used from the eighth wave. Logistic regression analysis was conducted to examine the influence of various factors. As a result, age, level of education, employment, subjective socioeconomic status, self-esteem, income, homeowner, and non-beneficiaries affected the economic preparation for aging. These findings have practical and political implications concerned with improving the economic preparations for aging among people with severe disabilities.

This study analyzed the different needs between the after-school programs of elementary schools in metropolitan and non-metropolitan areas to understand the areas that need addressing to meet with the requisites of the programs. To this end, this study conducted a survey among teachers with experience in after-school management (n=233), and the needs and performance recognized by teachers were analyzed in the IPA model matrix. To sum up the results, 'Online educational infrastructure', 'Efficient administrative operation', and 'Supply of professional after-school instructors' were identified as the prior needs in metropolitan area. On the other hand, non-metropolitan area, 'Supply of professional after-school instructors', 'Quality educational contents', and 'Online educational infrastructure' were identified as the prior requisites to be addressed. Based on research findings, the study suggested implications in developing and implementing related policies. Research findings will be expected to refer as baseline data for activating after-school online program operations and improving its programs to meet with the different needs of regions.

신재생에너지 수요가 확대됨에 따라 신재생에너지 관련 제품에 소요되는 물질에 대한 관심이 확대되고 있다. 이들 물질은 공급리스크가 존재하는 희유금속이 주를 이루고 있다. 본 연구에서는 신재생에너지 등의 high tech 기술 확대로 인한 희유금속의 수요 및 공급을 전망하고 있는 미국의 critical raw material 관리 전략을 살펴보고자 한다. 미국은 2010년 12월 미국 에너지성(DOE : Department of Energy)에서 위기 물질 전략(Critical Materials Strategy)에 관한 리포트를 공표하였다. 클린 에너지 기술 4개 분야(영구자석, 선진 전지, 태양전지 박막, 형광 물질)에서 핵심이 되는 물질(희유금속 등)의 수급 불균형이 일어날 가능성에 대해 조사를 실시하여 리스크 평가하여 단기, 중단기로 구분하여 위기물질을 선정하였다. 클린 에너지 기술 4개 분야에서 핵심이 되는 물질(네오디움, 디스프로슘, 코발트, 리튬, 랜턴, 세륨, 테룰, 인듐, 갈륨, 유로피움, 테르비움, 이트륨)의 12광종 수급을 2025년까지 전망한 결과 전체적으로 단기(2010년~2015년)보다 중기(2015년~2025년)에 공급 부족이 확대한다고 예측되었다. 단기적으로는 인듐이 약간 부족하는 것 외에 디스프로슘과 이트륨에 관해서도 공급 부족할 것으로 예측되었다. 중기적으로는 코발트(전지 기술에 사용)와 유로피움(고효율 조명용의 형광 물질에 사용) 외 대상이 된 다른 모든 물질은 공급 부족이 발생할 것으로 전망되었다. 이를 종합하여 단기적으로는 디스프리슘, 유로피움, 인듐, 테르븀, 네오디움, 이트륨 등이, 중기적으로는 디스프리슘, 유로피움, 테르븀, 네오디움, 이트륨 등이 위기물질(Critical Material)로 분석되었다. 에너지성은 위기물질을 공급원다각화, 대체물질개발, 리유즈, 리사이클링 등을 국제적 파트너와 함께 추진하여 리스크를 관리할 것이며, 2011년까지 최신정보를 구축하여 위기물질 전략을 재설정할 예정이다. 체계적인 위기물질 선정 및 관리전략 등을 참조하고, 신재생에너지기술 변화에 따른 원재료의 중요성 및 리스크 관리현황을 기초로 우리나라에 적합한 위기관리 물질 선정 및 관리가 필요할 것이다.

In the early 90s, we had serious shortage of construction engineers for the expansion of construction market. So, Government has established the admitted engineer system in 1995. However, since year 2000, while the engineershortage has been resolved, the opposite situation has occurred: serious over-supply of construction engineers. Therefore, Government announced that would abolish the admitted engineer systems as recognized the existent admitted engineers from 2007. From this point of view, it is critical to make the accurate forecast of number of required construction engineers for providing the basis for the most appropriate policy from 2008 to 2017. This research have developed a construction engineer supply-demand forecast model based on the GDP and construction market analysis. The results of this research will be applied to the basic data that policy planner establishes the supply-demand policy of construction engineers.

The supply and demand planning the pediatric dentists is earnest, because of the start of the dental specialist system on 2008 and aging society with low fertility. Therefore in order to develop the model, that is adequate to estimate demand for the pediatric dentists, a studies on the supply and demand planing of other health manpower were reviewed. The obtained results were as follows : 1. The health demand method was appropriate for demand estimation of the pediatric dentists. 2. There was independent variables needed for demand estimation model: prevalence, utilization rate, referral rate, fertility rate, productivity, annual working days, and so on. 3. Since statistical data for application of these variables was insufficient as result of searching, questionnaire researching and discussion of specialist may be necessary. 4. Each independent variables should be inducted into an equation by using a adequate regression model and then estimated.

OES survey as the national official statistics aims to provide the basic data for the national labor market policy and research such as the basic statistics for human resource supply policy, the prediction of employment by occupations, the decision of occupation, the occupational training and the finding jobs et al., at the levels of industrial and occupational classifications(3-digit). In order to achieve this objective, we analyze the OES data in 2005 and 2006 and propose the new sampling design using the long form data in Korea (10% sample data of census 2005). In this paper, we provide the criterion of sample allocation and derive the formular for estimator and error of it including the weighting procedure. From the proposed sampling design, we would expect that it contributes to the supply policy of human resource and the research for labor market.

This study was to estimate total annual volume growth by the measurement of mean tree growth during the last 10 years. Surveyed Forest stand was the second block (20.80 ha.)of Kyung Hee University Forests located at San 58 and 64, Gaegok-Ri, Gapyung-Yeup, Gapyung-Goon, Kyunggi province in Korea. The stand was mainly composed of uneven-aged Pinus densiflora and the estimation of tree volume was conducted by taking the cores at the D.B.H. of the sample tree which was selected by sub-sampling. The results obtained were as follows; 1) The regression between the diameter (D) and diameter growth ($\hat{I}$) was $\hat{I}=0.5499+0.0101D$. 2) The estimated equation of confidence interval for the diameter growth was $S^2{\hat{I}}=0.00817(0.09538-0.00952D+0.00027D^2$) 3) The equation for estimating tree height (H) from diameter was $H=1.32376D^{0.77958}$ 4) The equation for estimating tree volume from diameter and height $V=0.0000622D^{1.6918}H^{1.1397}$ 5) Total annual tree volume growth was $5.4041m^3/ha$, and ranged from 5.6131 to $5.1984m^3/ha$. 6) Annual growth rate of total tree volume and its error were 8.8% and 3.9%, respectively. The annual volume growth per tree for any districts can be estimated by this method, and the annual volume growth will be successfully predicted. Because of poor forest growing stock in Korea, annual amount of allowable cut should not exceed annual tree volume growth for better forest management. Accordingly, annual amount of allowable cut should be either equal to or less than annual tree volume growth for the balanced establishment between timber supply and demand in Korea. Demand shortage will be substituted with imported timber. Such plans enable Korean Government to develop a better policy of forest resources management.
