교육용 컨텐츠의 중복 개발에 따른 국가적으로 많은 비용이 소요되고 있으며, 이를 해결하기 위해서는 전국적인 컨텐츠 공유시스템의 도입이 절실히 필요하다. 컨텐츠 공유를 위해서는 메타데이터에 대한 이해와 선행 연구가 필요하다. 이 논문에서는 국내 표준 메타 데이터에 관한 선행 연구를 기반으로 하여 교육용 컨텐츠 공유 시스템을 설계 및 구현하고 이를 2개의 교육청에 현장 적용한 결과와 전국 교육정보 공유시스템에 방향을 제시한다.

The daunting challenge thai today's educational organizations face is how to improve academic quality while containing or reducing costs. This paper discusses major changes in the educational environment and ICT-based course improvement efforts; examines some successful cases for course redesign, and proposes an e-education strategy for an educational institution to use ICT strategically in order to achieve both academic quality improvement and cost reduction together.

The purpose of this study was to analyzed the effects of educational recognition sub-factors (necessity, utility, value, cost, adequacy) on the field usability and satisfaction and the correlation between each factor for 220 applicants who have taken the national technical certificate of cosmetologist (make-up). In the practical courses of makeup certificate, the most-used course was selected as beauty makeup. It found for improvement need cause there was a high necessity and there was a low recognition of the cost, the number of annual written and practical test in the recognition of certification education. In field usability 'Beauty make-up utilization' showed high recognition, and it showed high satisfaction for acquisition of certificate satisfaction, 'The salary' showed low recognition. The necessity, cost, adequacy among educational recognition sub-factor of the national technical certificate had a significant positive effect on the field usability and satisfaction, and showed the most effect as adequacy on the field usability and the cost on the satisfaction. Therefore, efforts are needed to reduce acquisition costs of certificate and improve highly available theories and technique for segmentation and specialization of make-up certificate.

The purpose of this study is to predict the long-term maintenance expense of BTL school projects which were ordered from the Ministry of Education and Human Resources Development and each Metropolitan and Province Office of Education. For conducting this study, the adapted research method includes a case study of BTL school projects ordered from Seoul Metropolitan Office of Education in 2006. After examination of initial investment based on each $school^{\circ}{\phi}s$ operation account, it estimates maintenance expense and long-term maintenance expense. Also it compare using two methods: one is the long-term maintenance expense estimation in apartment houses and the other is AEAM(annual equivalent amount method). The results of this study are as follows: 1) It is analyzed long-term maintenance expense rates of each BTL school. As a result, it is construction(14.0), civil(1.4%), mechanical(6.5%), equipment(6.5%), electronic(11.0%), fixture(5.1%) and the rest(1.0%). 2)It is applied using two methods: one is the long-term maintenance expense estimation in apartment houses and the other is AEAM. Finally, It is compared expense deflection per $100{\beta}{\ge}$ in each month.

Construction cost estimation in the early phase provides the opportunity to make reasonable decisions related to the project. For estimating this cost, various methods have been developed. But several problems have been recognized like accuracy, relation beteewn design and cost etc. In this study, we developed the method of cost estimating for building parts. The modified method has defferent ratio of space functions to calculate cost more correctly. Also historical cost data is used in this modified method for architects to estimate cost conveniently. By this modified method, we expects architects should easily design buildings based on cost.

The purpose of this research is to identify problems and solutions of domestic Life Cycle Cost analysis in BTL(Build-Transfer-Lease), a PFI(Private Finance Initiatives) project. It is expected BTL would be quite effective delivery method for public construction introducing the private's major capital investments and technologies, and obviously LCC analysis is becoming more important factor for success of BTL projects. Nevertheless, there are still some complicated issues in LCC analysis, a technique for selecting the optimal VE(Value Engineering) proposals and estimating OM&R (Operation, Maintenance, & Repair) cost of the buildings, and has been applied limitedly. This research mainly focuses on educational facility, as most frequently delivered by BTL currently, especially with two levels (Alternative LCC and Building LCC) , which is occupied main potion in BTL project. In addition, it identifies four main problems and suggests their solutions through case studies focusing six major factors (WBS, Repair Information, Life Cycle, Time value of money, Repair Information Database, LCC Model) from three projects. Advanced development of this research requires closer partnership between the private / public sectors, and their long term strategies.

This study estimates the VSL(value of a statistical life) as well as the WTP(willingness to pay) for mortality risk reduction using sample selection model with data on liver cancer examination which is associated with little possibility of multi-purpose(i.e. joint production) in averting behavior. The marginal benefits of mortality risk reduction are estimated by applying for household production function model with medical expense and the time required for medical examination of liver cancer. Individuals are more likely to take liver cancer test if they are male, older, higher educated, those with spouse, smoker, more income of household, and more anxious about their health. The costs of liver cancer examination are statistically significantly affected with expected signs by size of mortality risk reduction, sex, period of eduction, those with spouse, and household income. The marginal effect of mortality risk reduction owing to taking liver cancer examination is estimated at 321,097 won. The costs of liver cancer examination are increased by 905 won with more one year of education period and by 1,743 won with more one million won in household income. On liver cancer examination, male spends more 12,310 won than female and those with spouse pay more 7,969 won than those without spouse. Therefore the VSL from mortality risk reduction due to liver cancer examination is 321.10 million won at mean size of mortality risk reduction and mean cost of liver cancer examination. The results of sensitivity tests on costs and effects of liver cancer test shows that the VSLs are estimated in a range from 160.55 million won to 642.19 million won.

교육인정자원부가 부족한 교육재원 확보를 이유로 이미 위헌판결이 내려진 학교 시설 용지부담금 대신 아파트 사업자들에게 학교 시설 비용 일체를 부담하라는 새로운 해석으로 민간 건설사들의 강한 반발을 사고 있다. 기존의 대단지 아파트 입주민들에게 부담금을 전가하는 것은 위헌이라는 판결을 받은 바 있는 학교용지부담금이 다시금 쟁점화됐다.
