The purpose of this research is to analyze the performance of national R&D projects and to find out measures to improve the performance indicators, focusing on energy HRD projects. The main analysis target is 86 energy manpower projects supported since 2010. The performance indicators of the energy HRD projects are related to the research capacity, the number of emission workers, industry-university linkage, job creation and so on, and analyzed by using the 11 indicators of human resource performance index called KPI index. As a result of analyzing the attainment level of the proposed target by task, the index with the highest achievement level is the corporation linkage rate, and the index with the lowest achievement level is the participating company employment. As a result of examining the effects of job creation in company - linked activities, it was found that the greater the number of participating companies in the business, the greater the employment creation effect of the number of internships. As a result of the above analysis, the following policy alternatives are proposed. First, it is necessary to consider adding indicators that can express the quality performance of the business and performance indicators that can express actual business linkages. Second, it is necessary to strengthen the management of differentiated performance indicators according to policy performance targets and major target groups. Third, it is necessary to improve information input and accumulation system along with improvement of performance index.

In the knowledge-based economy, the accumulation of technological knowledge is undoubtedly the core competency to reinforce the competitiveness of individual firms and to raise the innovation capability of social and economic systems. Thus far, however, only single or fragmentary indicators, such as R&D expenditure, R&D stock, the number of researchers and the number of R&D employees have been adopted to measure the amount of technological knowledge. In this research, we suggest an approach for aggregating and structuring respective indicators. Applying correlation and factor analysis, we examine the relationship among nine conventional proxy measures for technological knowledge and present a new approach for gauging an aggregated measure.

본 논문에서는 최근 건축공간에 있어서 음환경에 대한 관심이 놓아지면서 학교 건축물에 있어서 강의실내의 음환경을 측정하고, 학교건축물에 대한 음환경 기준을 확립하는 데에 기초자료와 필요한 제안을 하는 것이 목적이다. 현재 음환경 기준은 단순히 소음fp밸이나 잔향 시간과 같은 단순한 물리특성만을 기준으로 하고 있다. 여기서는 강의실 내의 잔향시간, D, STI 등외 물리지표와 설문조사 등 주관적 평가를 통해 새로운 음환경 기준을 제시하려고 한다. 여기서 사용되는 물리지표로는 TSP(Time-Streched-Pulse)신호를 사용하여 잔향시간과 D(Deutlichkeit), STI(Speech Transmission index)를 산출하였다. 강의실의 화자의 위치에서 1.5m 높이에 스피커를 놓고 청취자의 위치인 여섯 점에서 무지향성 마이크로폰을 1.2m 높이에 놓고 마이크로폰으로 들어온 임펄스 응답을 측정하고, 강의실 내의 잔향시간과 D, STI를 산출하였다. 다음에 설문조사를 실시하여, 앞에서 측정한 물리지표와 설문조사를 통해 얻은 주관적 평가와의 상관관계를 파악하였다.

Recently, data gathering and algorithm developing are in progress for the GIS application using point feature. Several researches prove that verification of the spatial clustering and evaluation of inter-dependencies between event and control are possible. On the other hand, most of the point features as GIS data are gathered by indirect method, such as address geo-coding, rather than by direct method, such as field surveying. Futhermore, lots of statistics by administrative district based on the point features have no coordinates information of the points. In this study, calculating the K-index in GIS environment, to evaluate the effect of aggregation of raw data on K-index, K-indices estimated from raw data (parcel unit), topographically aggregated data (block unit), administratively aggregated data (administrative district unit) are compared and evaluated. As a result, point feature, highly clustered in local area, is largely distorted when aggregated administratively. But, the K-indices of topographically aggregated data is very similar to the K-indices of raw data.

Database workloads may show different resource usages for database applications. Database administrators can enhance the DBMS performances through resource management that reflects workload characteristics. We provide a method that can identify tunable resources from analyzing the relationship between performance indicators and resources. First, we select which performance indicators increase or decrease by expanding resources using a correlation coefficient and a significance level test. Next, we identify resources that can affect the DBMS Performances by using increasing or decreasing performance indicators. We evaluated our method in the TPC-C and TPC-W environments.

In this paper, the surface settlement resulted from the shallow TBM tunnelling has been numerically simulated. TBM tunnelling is especially used in urban area to avoid serious vibration and noise caused by explosion in NATM. Surface settlement is one of the most important problems encountered in all tunnelling and critical in urban areas. In this study, face vibration of TBM excavation is considered to estimate surface settlement trend according to TBM extrusion. The dynamic excavation forces are calculated by total torque on the TBM cutterhead in mixed-face of soil and weathered rock condition with shallow depth. A 3-dimensional FDM code is employed to simulate TBM tunnelling and mechanical-dynamic coupling analysis is performed. The 3D numerical analysis results showed that dynamic settlement histories and trend of surface settlement successfully. The maximum settlement occurred at the excavation point located at 2.5D behind the face, and the effect of face vibration on the surface settlement was verified in this study.

The application field of OSS is being expanded farther and the existing studies are well established theoretically but not actually widely used. Because so many criteria and complexity of selection methods result in low efficiency and not proper for use. In this master's thesis, to solve these problems I propose a selecting technique for OSS with less criteria, which is more effective and easy to use than before. Based on the existing studies, we identify assessment criteria which common used and redefine 14 evaluation attributes as well as 31 assessment criteria through elimination and grouping. And evaluate the criteria in four steps such as Initial assessment, Functional assessment, Characteristical assessment and Supplemental assessment. To evaluate the adequacy of suggested technique, 29 database management tools for MySQL are selected as candidates, and applied to the technique I proposed. As the result, time and effort for evaluation is reduced sharply and we can use this technique more easily.
