This study analyzed the effect of career development system and personnel management equity on career success for workers who experienced various career change environments. The results of empirical study were as follows: First, it was found that career adaptation partially mediated career development system and career success relationship. Second, it was found that the moderating effects of personnel management equity on career success and career adaptation respectively. Third, it was found that the moderating effect of personnel system fairness was mediated by career adaptability in the relationship between career development system and career success. The analysis results confirm the importance of career adaptability and personnel system fairness for individual career success and suggest that the effectiveness of the career development system can be increased when the characteristics of career development and the personnel system are combined.

For economic impact analysis on a R&D project of high-yield groundwater development in Jeju conducted by KIGAM from 2004 to 2007, benefit/cost ratio(BCR), net present value(NPV), and internal rate of return(IRR) were calculated by contingent valuation method(CVM), production function analysis, domestic water market analysis and technology factor analysis. Measurable direct impact parameters among the major outputs of this R&D project consisted the estimation 4 high-yield and high mineral groundwater reserve in Jeju. Annual use of the reserve by piped water and bottled water was estimated as 12.23 million ton and its monetary value was calculated as 293.4 million dollar in 2006 year value applied of 5.5% discount rate. Economic impact of this R&D project in NPV of year 2006, with applying a discount rate of 5.5%, was identified and estimated as 13.66 million dollar in NPV, 4.05 points in BCR, and 22.74% in IRR, respectively. Additional early launch benefit was 5.58 million dollar. Even increased of the 1% discount rate, NPV of this R&D project was also positive as 12.18 million dollar and BCR was 3.71.

본 논문은 레이더 유량계를 활용하여 영구저류지의 유입·유출량을 계측을 통해 영구저류지의 재해저감효과를 분석하였다. 2009년 이후 자연재해대책법 의거 개발사업에 대해 재해영향평가를 실시하고 개발 후 영구저류지를 설치토록 법제화하고 있다. 재해영향평가서 상 50년 빈도 강우량으로 영구저류지를 설계하고 있지만, 크기 및 형태에 대한 평가는 이루어지지 않고 있으며, 이상기후로 인해 강우강도가 높은 폭우가 지속적으로 증가하고 있어 이에 대한 평가가 필요한 상황이다. 영구저류지의 재해저감효과를 확인하기 위해 유입·유출구에 레이더 유량계를 설치하였고 24시간 강우사상 동안 발생한 유입·유출량을 확인하였다. 획득 데이터를 통해 사전재해영향검토서의 기대 저감효과 영구저류지의 실제 저감효과 비교 분석을 하였고,이를 바탕으로 저감효율을 계산하여 영구저류지의 재해저감효과에 대한 구체적 평가를 수행하였다.

Backfill material with thermal resistivity which has $50^{\circ}C$-cm/Watt in wet and $100^{\circ}C$-cm/Watt in dry is requested to improve the power transfer capability for dissipation of heat production in underground power cables. In the field test performed by buried cable backfills, the backfill material developed from this study is compared with river sand and weathered soil (native soil) to investigate the effect of heat transfer in various seasons and locations of thermal sensors. As a result, the developed backfill material is faster approaching yielding temperature (critical heat) than that of river sand and weathered soil, and it has good dissipation capacity rather than other materials by keeping moisture content at dry season.

This study developed an adaptive instruction system for individual learning. We applied Gregorc's learning style to support the adaption. This proposed Instruction system provides instruction content based on a more effective instruction method that takes into consideration the learner's individual learning style. We applied Gregorc's learning style to create a clear treatment of differing learning styles. Proposed adaptive instruction system was applied to college students studying computer learning. A t-test indicated that our proposed adaptive instruction system resulted in positive effects in an overall style comparison. In addition, our Abstract-Sequential learning style indicated the most effective results while the Abstract-Random learning style indicated no difference between the experimental and comparative groups in each style analysis for Gregorc's learning style.

R&D projects for product development are crucial for ventures' growth and success. Current study summarizes existing studies that identify the relationship between startup ventures' R&D department, R&D investment, and R&D cooperation on product development performance, and highlights the effects of business model as well as the roles of R&D activities for product development project that have been traditionally emphasized. In order to consider the effects of business models that were not previously available, the effects of these factors on product development performance were comprehensively analyzed. The research results with 180 venture cases surveyed on venture companies in the growth stage in Korea, showed that the effect of product development project activities measured by R&D department, R&D investment and R&D cooperation on product development performance is not evident. However, the effect of business model on product development time and product development performance measured by product innovation was confirmed. In particular, it was found that the clarity and uniqueness of the business model interacted with the R&D investment to shorten the product development time and directly increase the innovativeness of the developed product. Based on these analysis results, the implications of this study, limitations of the study, and the future research directions were described.

R&D investment has rised in recent years. Korea's R&D budget is 43.8 trillion won which is 3.74% adjusted gross domestic product in 2010. Technological advances and technical inovation will bring productivity growth to Firm and Firm's productivity growth will increase GDP in sequence. Therefore the importance of study on the Firm's R&D industry is getting growing. In this study we attempt to analyse the economic impact of the Firm's R&D industry through several years using an inter-industry analysis. Specifically, this study analyze production-inducing effect, value added inducing effect, and employ-inducing effect based on demand-driven model. The analysed results of year from 1995 to 2009, the Firm's R&D investment increases production-inducing effect, value added inducing effect, and employ-inducing effect with the course of time. This means that influence of the Firm's R&D industry has increased.

현대는 연구개발부문의 다양화, 복잡화에 따라 기술정보량이 급격히 증가하고 있는 반면 기존의 연구소에서는 연구개발의 know-how 축적도 되어있지 않은 상태였으며, 연구개발조직의 분화로 인한 정보교환의 단절로 인하여 연구개발부문의 중복투자가 새로운 문제로 대두되었다. 따라서 이러한 기술정보를 체계화 하고 효과적으로 활용함으로써 연구개발의 과학 및 선진화를 추구할 수 있는 기초환경 조성의 일환으로 기술 Document시스템화의 필요성이 부각되었다. 이러한 배경하에서 당사는 연구소 개발업무의 체계화를 위하여 '92년 초부터 JMAC주관하에 진행되어온 연구관리코드체계를 근간으로 기술 Document시스템을 개발하게 되었다. 기술 Document시스템의 추진 목표는 document작성의 정형화, know-how의 체계적인 축적을 위한 기술개발전산화의 기반구축, 다양한 data들을 처리하기 위한 미래지향적 정보관리기반구축, on-line정보교환체제구축을 통한 연구생산성 향상, 이미 개발된 S/W의 효과의 극대화등이다.
