본 연구에서는 감성분석기법이 환경평가에 적극 적용되어지면서 쓰이는 감성평가모형을 선행연구조사와 실험을 통해 두 가지 축약형 모형과 추론형 모형으로 구분하였다. 또한 두 가지 유형의 대표 모형인 EPA모형과 PAD모형의 평가어휘들의 특성을 실험을 통해 분석해 본 결과, 두 모형은 개발방식과 어휘구성에 큰 차이가 있고, 요인분석을 통해 어휘들이 모형별로 축약되는 것을 확인하였으며, 유사성 관계를 다차원척도법으로 분석한 결과 서로 관계성이 어느 정도 성립되는 것을 확인하였다. 이를 통해 감성평가모형이 감성평가에 사용될 때는 한쪽으로 치우치기 보다는 모형의 특징을 분석하여 적용하면 보다 객관적인 이미지 분석이 가능함을 알 수 있다. 본 연구에서는 가로경관 환경평가로만 국한되었다면, 다양한 분야에서의 평가대상이 비교될 수 있는 감성평가모형에 대한 지속적인 연구가 필요하다.

It has been very important to have an exact evaluation for risk factors in order to prevent WMSDs(Work-related Musculoskeletal Disorders). However, most WMSDs evaluation methods have always been some problems of possibilities associated with subjective evaluation. Therefore, this study tried to conduct a sort of usability analysis on three major evaluation methods(OWAS, RULA, REBA). Specifically, major subjects in the study consisted of three parts as follows; comparison of the results between experienced and inexperienced observers, analysis for the consistency of the results in terms of different evaluation times, and analysis for the consistency of the results in terms of different job characteristics(based on the part of the automobile). The results of the study were summarized as follows; 1) There was statistically significant difference of the results by RULA and by REBA between experienced and inexperienced observers. This might be due to the fact that experienced observers have had better ability to detect the important working posture during evaluation. However, the results by OWAS did not give any significantly different results between experienced and inexperienced observers, 2) All three checklists applied by experienced subjects did not show any single result significantly different in terms of different evaluation times. This might have to do with high intra-observer reliability from some of previous studies, 3) The five parts of an automobile were selected as five major jobs with different job characteristics in the automobile industry. Specifically, they were door part, front part(hood, etc.), inside part(dash board, seats, etc.), rear part(trunk etc.), and bottom part. All three methods did not show any significant differences for the results from each observers. Further study on this subject would eventually provide a sophisticated evaluating guidelines for WMSDs regarding determination of observer-specific evaluation, identification of repetitive number of evaluations for stable results for each checklist, determination of job-specific evaluation methods, and so on.

Although lots of safety inspection and precision safety diagnosis have been conducted on concrete retaining wall, there is no comprehensive analysis on the basis of the accumulated data associated with the statistic. Especially, the concentrated management is necessary on the evaluation items that cause critical damages for the efficient performance. In this regard, this study conducted a correlation analysis between the 18 condition evaluation items and defect index for the concrete retaining wall as well as how each item affects the final defect index as much as in the manual. As a result, correlation coefficient between sliding and overturning was 0.601, which means that they have a strong correlation, and the most influential item on defect index is the condition of drainage that scored the 0.750 correlation coefficient. In addition, as a result of regression analysis, the condition of drainage with the 0.683 correlation coefficient has a strong correlation with the defect index. If the condition evaluation items are integrated or readjusted based on the results of the statistical analysis in this study, the more efficient and accurate maintenance will be possible.

국가지리정보체계의 구축 및 활용 등에 관한 법률(구법/NGIS Act, 2000)이 폐지되고 국가공간정보에 관한 법률(신법/NSDI Act, 2009)이 제정되면서 국가 공간정보 정책 평가시스템에는 많은 변화가 발생되었다. 구법과 비교할 경우 신법은 국가 공간정보 정책의 추진체계가 일원화되었다는 장점은 있으나 예산 요구권의 약화로 공간정보 정책의 법적 실현가능성은 약화되었다는 논의가 있다. 이러한 문제의식 하에 구법에서 신법으로 법률이 새롭게 제 개정되면서 나타난 평가체계의 변화를 분석하는 것은 매우 중요한 의미를 갖는다고 할 것이다. 따라서 본 연구의 목적은 구법과 신법에서 규정한 국가공간정보 정책 평가체계를 비교 분석하여 평가 제도에서 나타난 변화가 무엇인지를 분석하는데 있다. 주된 연구방법은 구법과 신법의 비교분석 방법을 활용하였다. 비교 분석대상은 평가추진체계, 평가주체, 평가대상 및 범위, 평가결과의 활용, 평가전담기관 등이다. 분석결과를 토대로 할 경우 국가 공간정보 정책 평가시스템의 개선방안으로는 평가목적의 명확화, 평가 전담기관 제도의 활성화, 평가결과와 인센티브 및 예산 연계성의 강화, 공간정보정책의 사전 사후 연계성 강화 방법론 모색, 상향식과 하향식 접근이 결합된 평가지표의 개발 방안 등이 필요하다는 것을 제안하였다.

Distribution of various illegal or counterfeit drugs of seven approved erectile dysfunction drugs and their analogues has been increased, causing health problems such as cardiovascular disorder, tachycardia, headache, or vision disturbance. We used liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) to determine the erectile dysfunction drugs and their analogues in various counterfeit drugs. Eleven erectile dysfunction drugs and their analogues were detected, with sildenafil and its analogues being the most counterfeited compounds (73.8 %), followed by tadalafil and its analogues (25.4 %). The limits of detection (LOD) and the limits of quantitation (LOQ) of liquid-type and solid-type negative samples ranged from 0.1 to 3.3 ng/mL or ng/g and from 0.3 to 10.0 ng/mL or ng/g, respectively. The recoveries ranged from 84.3 to 112.3 % and 83.2 to 110.2 %, respectively. The contents of sildenafil and tadalafil in the various counterfeit drugs ranged from 21.0 to 947.5 mg/g and from 0.2 to 170.2 mg/g, respectively.

This study aims to introduce missile live-fire during the ship operational test and evaluation(T&E) as a means of verifying the integrated combat capability(ICC) of various systems installed on naval ships. The research method identified domestic and foreign T&E systems and cases, and reports related to ICC, which were written during the ship's design stage. As a result of research, Republic of Korea is not conducting the missile live-fire at the ship T&E stage due to the lack of relevant systems, while the U.S. is conducting it based on the mission-based T&E and the end-to-end test system. As a way to improve within the current domestic ship acquisition systems, the reaction time analysis, a quantitative analysis result of ICC calculated at the ship basic design stage, was proposed to be verified by missile live-fire during ship operational T&E.

This study attempts to develop an interim evaluation system for the Integrated Rural Village Cluster Development Project(IRVCDP) which can secure its identity and sustainability, and induce its early settlement, and to derive plans for its steady progress. The evaluation system consists of three levels. The highest-order level is evaluation purposes, which describe IRVCDP's goals. They are expansion of income bases(EIB), improvement of living environments(ILE), strengthening of regional capabilities(SRC) and constructing effective project operation system(CEPOS). The second level is evaluation items, which each characterize the relevant evaluation purposes. The last level is evaluation indices, which observe achievement f3r evaluation purposes. 22 evaluation indices are selected to satisfy the purposes of this study through a brainstorming process and a survey on opinions of experts for those evaluation purposes and evaluation items which are derived from analyzing the IRVCDP's properties. The relative importance of the evaluation indices selected are determined through the AHP analysis. The most intriguing result from the AHP analysis is that strengthening of regional capabilities is found to be the most important one among evaluation purposes. It can be said that this result is parallel to a ultimate goal of the IRVCDP.

In this paper, a sound quality index for the evaluation of the vehicle intake noise was developed through a correlation analysis of the objective measurement and the subjective evaluation. First, intake orifice noise was measured at the wide-open throttle sweep condition. And then, the acoustic transfer function between intake orifice noise and interior noise was measured. Simultaneously, subjective evaluation was carried out with a 10-scale score by 8 special engineers. The correlation analysis between the psychoacoustic parameters derived from the measurement and the subjective evaluation was performed. The most critical factor was determined and the corresponding sound quality index for intake noise was obtained from the multiple factor regression analysis method. Finally, the effectiveness of the proposed index was validated.
