The facility diagnosis technique of past subjective judged the technical expert and interpreted stably mainly. The facility the periodical civil official becomes indispensability consequently with the law and the system and objectivity inspection which relates with a this and development of diagnosis technique were necessary. Currently the evaluation elements which relate with an inspection and diagnosis technique depended to the subjectivity of each facility quality, data statistics, diagnosis know-how, various circumstance and the technical expert and the evaluation item came to decide. But the evaluation score distribution of marks of each item depended plentifully in data analysis result and experience. The past method is weak in logically because the objection theoretical background and basis are insufficiency. Consequently in order to apply a data analysis result and an experience logically, it used AHP(Analytic Hierarchy Process) method from this research. It is visible with the fact that the application result reconfirmation and complement process will be necessary the technique which is suitable in the multi facility management. Also it is expected with the fact that the application characteristic from the next relation technique will be excellent.

The purpose of this paper was to measure technical efficiencies and scale efficiencies of Korean seed industry by DEA method, and to identify the factors affecting the efficiencies by Tobit regression model. Survey data of 50 seed companies nationwide were applied for the analysis. The average score of overall technical efficiency for the surveyed companies in 2012 was 0.44, which is decomposed into pure technical efficiency 0.68 and scale efficiency 0.63. A majority of the seed companies exhibited at least one form of inefficiency except a few companies in optimal scale. It was also shown the most companies were operating in the stage of increasing returns to scale, which implies Korean seed companies are mainly in smaller scale than optimal. Additional results suggest that the Center for Private Seed Companies, which will be established at Gimje in 2015, plays an important role to make domestic seed companies improve their scale efficiency as well as pure technical efficiency by way of enlarging their size and co-using the high technology in the Center.

90년대 이후 용수관리 정책이 공급중심에서 수요관리로 정책 전환이 되면서 공업용수 수요량이 급격히 감소하였다. 본 연구에서는 공업용수 사용의 기술적 효율성을 분석하여 이러한 공업용수 수요량 감소가 공업용수의 사용이 효율적으로 이루어진 결과인지 검토하고 향후 공업용수의 기술적 효율성 제고를 통하여 공업용수 사용량을 더 줄일 수 있는지 검토하였다. 본 연구결과에 의하면 공업용수의 기술적 효율성은 1998년도 0.5183에서 2003년도에는 0.4853으로 도리어 약간 감소한 것으로 나타났다. 이는 다른 투입요소의 기술적 효율성에 비하여 낮은 수치로 앞으로 기술적 효율성 제고를 통하여 공업용수 사용량을 더 절감할 수 있음을 보여준다.

The Korean government has provided various policy devices to boost technology transfers between academia and industry since the establishment of the Technology Transfer Promotion Act in 2000. Along with the enactment of the law, the Korean government mandated the establishment of a technology transfer office at national and public universities and encouraged technology transfer activities. Despite the quantitative expansion of technology transfer offices (TTOs), operational inefficiency was brought up. As a supplementary policy, the Korean government implemented a line of projects to support the labor and business expenses of leading TTOs. This research questions whether the project greatly affected the technical efficiency of TTOs. We analyze publicly available university panel data from 2007 to 2015 using a one-step stochastic frontier analysis. The results suggest that the program was marginally effective at shifting the technical efficiency distribution to the right on average, but it failed to maximize its impact by diversifying the policy means based on targets. The marginal effects of the program on technical efficiency differ according to the research capability and size of each school. We also compare technical efficiency against the licensing income at the start and end of the program. Technical efficiency increased for the leading TTOs, and both measures show improvements for unsupported TTOs. Our empirical results imply that diversifying the program for universities with different characteristics may have improved the effectiveness of the policy.

본 연구는 자료포락분석(Data Envelopment Analysis, DEA)을 이용하여 국내 건설회사를 대상으로 효율성을 측정하고 효율성의 연도별 추이를 파악하며 개별기업 및 산업차원에서 비효율성에 영향을 미치는 요인을 분석하였다. CCR모형 및 BCC모형을 적용하여 기술적 효율성 및 순수기술적 효율성을 측정하였고 Window분석을 통하여 연도별 효율성의 변화 추이를 파악하였다. 또한 비효율적인 기업을 대상으로 효율적인 기업이 되기 위한 목표치와 참조집합을 예시하였으며 수익성과 효율성의 시계열자료를 이용하여 효율성 측면에서의 선도기업을 도출하였다. 효율성에 영향을 미치는 요인으로 기업집단의 소속여부에 따른 효율성 차이를 검증하고, 매출액 중 건축비중, 토목비중, 외주비율 등과 효율성과의 상관관계를 식별하였다. 이와 같은 분석은 개별 기업의 효율성에 관한 벤치마킹 및 전략목표설정에 기여하며, 산업경쟁력을 높이기 위한 바람직한 정책 수립에 활용될 수 있다.

The results of diagnostics and analysis of an industrial hall located on the premises of a thermal power plant severely damaged by fire are presented in the paper. The comprehensive failure-related diagnostics, non-destructive and destructive tests of steel and concrete materials, geodetic surveying of selected structural members, numerical modelling, static analysis and reliability assessment were focused on two basic goals: The determination of the current technical condition of the load bearing structure and the assessment of its post fire resistance as well as assessing the degree of damage and subsequent design of reconstruction measures and arrangements which would enable the safe and reliable use of the building. The current mechanical properties of the steel material obtained from the tests and measured geometric characteristics of the structural members with imperfections were employed in finite element models to study the post-fire behaviour of the structure. In order to compare the behaviour of the numerically modelled steel roof truss, subjected to the effects of fire, with the real post-fire response of the damaged structure theoretically obtained resistance, critical temperature and the time at which the structure no longer meets the required reliability criteria under its given loading are compared with real values. A very good agreement between the simulated results and real characteristics of the structure after the fire was observed.

This study empirically examines the relationship between the career orientations of R&D professionals and their demographic characteristics (age, tenure, and education level), affiliated organizations (public and private organizations), reward systems. It further explores the contingent effects of the career orientation fit between leader and members on their performance. The results reveal that : 1) five different career orientations (technical, manager, project, technical transfer, and entrepreneur) are empirically distinguished, 2) technical orientation of R&D professionals is higher in public in private sectors, 3) technical, project, and manager orientation are positively associated with the education level, while technical transfer and entrepreneur orientation are negatively associated with the education level, 4) manager and technical transfer orientation is positively related with age and tenure, 5) the career orientation fit between leader and member is closely related with job satisfaction and organization commitment, and partially related with technical performance, 6) R&D professionals with different types of career orientation exhibit different preference to various rewards. Based on these findings, this study suggests several practical implications for the design of career ladder, mentoring, and reward systems of R&D professionals.

Scintillation that is grainy patterns appeared on a screen has been one of a biggest issues in a rear projection TVs. In this paper, with focusing on the average size of random particle, it was proved that the particle size of calculated speckle and the one of measured scintillation are almost the equal. This result shows speckle phenomenon is an important factor of scintillation.
