  • Currently, RC slab bridges in use in Korea account for most of the total bridges, and bridges with a service life of 20 years or more account for about 75%. However, most of these RC slab bridges have a span of less than 20m and are not included in the first and second types of facilities, so maintenance is very neglected. Therefore, in this study, field load test is performed on an aged RC slab bridge, and the performance evaluation is performed based on the structural response results (deflection, impact coefficient, natural frequency, etc.) of the bridge obtained through field load test. In addition, the performance evaluation results obtained through the load test are intended to be used as basic data for the damage evaluation process of the bridge currently under development.

  • In this study, the library ESG evaluation indicators specialized for libraries were developed, and based on which, a survey was conducted targeting the actual libraries to evaluate the ESG level of libraries. As a result of the study, first, among the ESG evaluation indicators, the indicators of the social field and the governance field are demonstrating high in which field of the library's ESG evaluation indicators will appear the highest. The social area's high score of 3.70 seems to be because the protection of users' rights, occupational safety, and contribution to society and the local community are very closely related to the original role of the library. Second, it may be seen that there is a difference between the questions in the corporate governance part, while the averages are the same. In the case of library's cooperation, it turned out that it was 3.94 in the necessity evaluation of the evaluation indicators, but it was lowered to 3.61 in the actual library situation evaluation. Meanwhile, in connection with the activities of the director of library and the board of directors, it may be seen that the index evaluation increased from 3.32 to 3.58 in the actual evaluation.

  • Evaluation method of soil fertility by combination of soil color characteristics and survey data from soil map as well as chemical properties was investigated on total 35 field and pot experiments. Total 35 tobacco fields including 11 fields located at Cheonweon county in Chungnam Province, 9 fields located at Goesan county in Chungbuk Province, and 15 fields located at Youngcheon county in Kyongbuk Province were selected in 1984 to cover the wide range of distribution in landscape and soil attributes. Yields of tobacco grown on the plots of both the pot and field experiment which were not applied with any fertilizer were considered as basic fertility of the soil (BFS). The BFS was estimated by 32 independent variables including 15 chemical properties, 3 color characteristics, and 14 soil survey data from soil map. Twenty-four independent variables containing 16 quantitative variables selected from 24 quantitative variables by collinearity diagnostics and 8 qualitative variables, were classified and analyzed by multiple linear regression (MLR) of REG and GLM models of SAS. Tobacco yield of field experiment showed high variations by eight times in difference between minimum and maximum yield indicating the diverse soil fertility among the experimental fields. Evaluation for the BFS by the MLR including quantitative variables was still more confidential than that by a single index and that showed more improvement of coefficient of determination ($R^2$) in pot experiment than in field experiment. Evaluation for the BFS by MLR in field experiment was still improved by adding qualitative variables as well as quantitative variables. The variability in the BFS of field experiment was explained 43.2% by quantitative variables and 67.95% by adding both the quantitative and qualitative variables compared with 21.7% by simple regression with NO$_3$-N content in soil. The regression evaluation for the best evaluation of the BFS of field experiment by MLR included NO$_3$-N content, L value, and a value of soil color as quantitative variables and available soil depth and topography as qualitative variables. Consequently, it is assumed that this approach by the MLR including both the quantitative and qualitative variables was available as an evaluation model of soil fertility for tobacco field.

  • 신종 및 재출현 전염병이 지속적으로 유행하고 해외 전염병의 국내유입 가능성이 증대됨에 따라 국립검역소의 검역관리 사업의 효율성 평가는 매우 중요하다. 본 연구는 평가 구성요소 사이의 상대적 중요도, 즉 가중치(weight) 부여에 있어서 과학적 타당성을 인정받고 있는 계층분석절차(Analytical Hierarchy Process; AHP) 기법에 의한 이원비교방법을 사용하여 설정하였다. AHP기법은 복잡한 다기준 의사결정문제(multi-criteria decision making problem)를 계층화하여 단순화 체계화시킴으로써 그 영향도를 계량화하는데 탁월한 기법이라는 평가를 받고 있다. 평가지표별 가중치는 기관평가 영역이 0.2, 서비스 및 프로그램 영역이 0.8로 분석되었으며, 서비스 및 프로그램 영역내에서 검역 업무가 0.45로 가장 높게 나타났다. 대영역(기관평가영역, 서비스 및 프로그램평가 영역), 중영역(투입, 과정, 결과, 검역업무, 검사업무, 위생관리업무, 병원체조사감시업무, 전염병예방홍보 교육업무)으로 구분하여 최종적으로 평가지표로 선정된 지표는 실제 국립검역소 사업에 적용하였으며, 이에 대한 최소한의 평가지표를 최종 선정하여 향후 국립검역소 사업평가 체계를 보다 체계화 하였다.

  • 정부는 검정형 자격제도의 한계를 극복하고 관련 산업계에 적용가능한 실무능력 인재 양성을 목적으로 과정평가형 자격제도를 운영하고 있으며, 지적분야도 지적산업기사 등급의 과정평가형 자격제도를 운영중에 있다. 그러나 과정평가형자격의 교육훈련과정에 지적분야가 아닌 측량분야의 능력단위를 교육함으로서 과정평가형 자격제도의 취지와 맞지 않는 부분이 있다. 따라서 본 연구는 지적분야의 과정평가형 자격제도를 면밀히 분석하고 그에 따른 개선방안을 제시하였다. 첫째, 지적분야의 NCS는 2014년 개발이후 별다른 보완·개발이 이루어지지 않아 현행 법령과 맞지 않는 부분이 다수 존재하므로 이에 대한 보완개발이 필요하며, 둘째, 현행 지적분야 과정평가형 자격제도에 활용하고 있는 측량분야의 선택능력단위를 지적분야의 NCS 능력단위로 개선할 것을 제안하였다. 또한 현행 지적분야의 NCS의 12개 능력단위를 필수능력단위로 지정하고 교육·훈련을 운영한다면 충분히 지적기사 등급의 역량을 갖춘 실무인재를 양성할 수 있을 것이므로 지적기사 등급의 과정평가형 자격제도 도입을 제안하였다. 그러나 실질적인 제도운영 및 적용을 위해서는 과정평가형 자격제도 교육·훈련에 활용되고 있는 지적분야 NCS의 보완·개발이 반드시 선행되어야 할 것이다.

  • Near-field ground motions exhibit special characteristics that are different from ordinary far-field ground motions. This paper first briefly examines the characteristics of near-field ground motions associated with fault directivity and fling-step effects. Then evaluation of near-field ground motions by inelatstic response spectrum analysis is performed and analyzed. As a result, ductility demand in near-field ground motions is larger in hanging wall than in foot wall in long period regions. Also in long period regions ductility demand in soil site is larger than that in rock site.

  • This paper deals with analytical techniques for performance evaluation of small scaled wind power generator with outer permanent magnet rotor. In part (1), using transfer relations theorem, magnetic field distribution characteristics by PM and armature reaction field are derived. Moreover, electrical parameters such as back-EMF, inductance and resistance are calculated from the obtained field characteristic equations. The proposed analytical techniques are validated by nonlinear finite element method using commercial software 'Maxwell' and performance experiments of the manufactured generator. In part (2), generating characteristics analysis such as constant speed characteristics and constant resistive load characteristics, and performance evaluation according to variation of wind speed will be accomplished using the derived electrical parameters.

  • It is important to estimate the distribution of intensity of a magnetic field for application of magnetic method to industrial nondestructive evaluation. Magnetic camera provides the distribution of a quantitative magnetic field with homogeneous lift-off and same spatial resolution. And it is possible to interpret the distribution of the magnetic field when the dipole model is introduced. This study introduces the numerical and experimental considering of the quantitative evaluation of several size and shapes of the cracks using the magnetic field images of the scan type magnetic camera.
