Fragility analysis is widely used for the seismic safety evaluation of a structure. In fragility analysis, damage evaluation is a crucial factor. Most of the present fragility analyses use the representative responses such as displacement and absorbed hysteretic energy as a tool of damage evaluation. But damage evaluation method that can represent the local damage of a structure is required in the case of piers of which the local damage can cause the whole failure of bridge system. Therefore this study proposes a damage index, which can represent the distribution and magnitude of local damage by using the Lee and Fenves'plastic-damage model. Using the proposed damage index, fragility curves and damage probability matrix of pier are produced and fragility analysis is performed.

This study aimed to evaluate the room acoustical performances of multi-purpose halls, surveying the architectural features and analysing the acoustical characteristics by measurements. In addition, adjectives appropriate for the evaluation of the room acoustical performance in multi-purpose halls were determined through the method of questionnaire survey and subjective evaluation through psycho-acoustic experiment. The results from the experiment were analysed by the correlation analysis and the factor analysis, consequently useful adjectives for the evaluation of acoustical performances in multi-purpose halls were determined depending on the types of performance.

본 연구는 1990년 초부터 현재까지 대학에서 개설되고 있는 모든 교과목을 대상으로 강의 평가를 수행하여 오고있는 H대학을 중심으로 이 대학에서 수행된바 있는 강의평가 분석 내용가운데 1998학년도 평가 결과만을 발췌하여 요약한 것이다. 강의평가 결과는 전체적으로 어떠한 경향을 보이고 있으며, 개별강의 평가결과는 어떠한가? 또 영역별 평가에서는 어떠한 차이를 나타내고 있는가? 등을 구명하기 위하여 7개 영역 10개 항목으로 구성된 설문 내용을 OMR용 카드를 통하여 작성하게 하였다. 강의 만족도에 가장 큰 영향을 미치는 변수를 분석하고 측정도구의 타당성을 검증하기 위하여 T-test와 Anova변량분석, 회귀분석 등의 통계분석 기법을 적용하였다.

Usability has become a primary factor in determining the acceptability and consequent success of consumer product. It is common that the product usability is evaluated by objective performance measures and/or subjective user preference measures. This study is concerned with objective evaluation of the product usability using 3-dimensional motion analysis. We evaluated car-audio position using 3-dimensional motion analysis. The parameters investigated in this experiment were height of car-audio, left-right angle, and front-end angle. The experimental results showed that the usability evaluation method using motion analysis was consistent with user's subjective assessment. This objective method can be applied to not only car-audio position evaluation but also various consumer products'usability evaluation.

Success in Knowledge Management depends critically on the evaluation system that managers of an organization evaluate objectively performance of members of the organization. In particular, the differences in the standard of Performance evaluation used by managers in Governmental Institution or Agency of make an issue of the standardization of Performance evaluation. Therefore, in this paper we propose the alternative evaluation method, which minimizes the bias resulted from the different standards by measuring ranking of knowledge workers, instead of quantitative analysis, using Median Rank method in Reliability and verify our proposition using the analysis of examples.

Following a 5.8 magnitude earthquake on September 12, 2016 in Gyeongju Province, a magnitude 5.4 earthquake occurred in the northern region of Pohang City on November 15, 2017 in South Korea. Only 7.9 % of the building structures are earthquake-resistant, according to the recent survey conducted by the government agencies in October 2017. In this paper, the linear analysis seismic performance evaluation procedure of the existing school structures presented in the revised methodology(Seismic Performance Evaluation Procedure and Rehabilitation Manual for School Facilities) was introduced. In this paper, the linear analysis evaluation procedure presented in the revised methodology was introduced and the seismic performance index of the example structure was evaluated using the linear analysis evaluation procedure. The seismic retrofit was verified by the linear and nonlinear dynamic analyses using Perform 3D. The analysis results show that the dissipated inelastic energy is concentrated on the retrofitted shear wall and the maximum inter-story drift of the stadium model structure with damping system satisfies the requirement of the current code.

This study has a goal to read a trend of language research by analysing evaluation tools and methods that researchers have used for assessing young children's language abilities. Thus the study has chosen 237 language ability evaluation methods out of 121 young child's language ability evaluation researches. The treatises were selected from 4 types of early childhood education journals registered on the Korea Research Foundation. The data analysis was employed for processing the frequency and percentage of the collected data. The results were as follows: First, of single age groups the subject group most selected was five-year-olders and of mixed-age groups the subject group most selected was from three to five, and the number of subjects in researches were mostly below fifty children. The researches were sorted into an 'experimental/ investigational researching' type that has been frequently re-utilized by others, an 'interview type' using a data collection method, and a 'difference verification' type using a data analysis method which has been used in majority of studies. Second, the number of treaties that required data analysis has increased since 1996. Concludingly, the analysis of young child's language ability evaluation tools shows that the purposes of many researches were concentrated on studying children's knowledge about language, children's language functions such as speaking, reading, writing and listening, while evaluation contents were focused on speaking and writing.

This study researches the effectiveness of virtual experiences as an evaluation method in design. For the study, I researched the result on the spatial recognition before, abstracted visual objects and factors in recognition process and made up 43 inquiries for the evaluation through the experts group. Besides, set the analytical code between recognition factor and spatial constituents, made analysis the result from it. From April 1st to June 30th in 2004, the virtual model of educational place, college main building and city library was established as a subject of the research and studied the result. The methods that are used for the study are frequent analysis, T-test, reliability analysis, factor analysis etc. and SPSSWIN Package is used for the statistic analysis. There were two times of analysis on the evaluation to analyze the effect of virtual models on the web basis, one group evaluated the virtual building same as real and the other group evaluated the building site. Then analyzed the differences and correlation between the two. In result, college building, the first subject of study, and the second city library shows that made little differences between on the spot evaluation and virtual evaluation. Therefore, it is considered that the design evaluation with virtual model on the web basis has a vantage. But some problems founded that solved between preceding and present research through the feedback. It is as follows, 1. detection of problems that insufficience validity in the first survey. 2. found some not-validity inquiries. 3. detection of necessities that qualitative improvement and technical repletion in virtual environment.

실제 환경보다 더 안전하고 적은 비용으로 실제 훈련과 유사한 학습효과를 기대할 수 있는 가상훈련(Virtual Training)이 최근 주목받고 있다. 그러나 기존의 가상훈련 시스템들은 학습자의 훈련결과에 대한 평가를 평가자의 정성적인 판단에 의존해온 경우가 대부분이었다. 또한, 평가와 분석 기능이 해당 시스템에 국한이 되어 시스템마다 별도의 평가 분석 시스템이 필요했다. 본 논문에서는 가상훈련의 효과적인 평가와 분석을 위해 전문가의 경험지식을 활용하는 확장성 있는 가상훈련 평가 분석 시스템을 제안한다. 우선, 제안하는 시스템이 다양한 형태의 가상훈련 시스템과 연동될 수 있도록 Open API의 적용 방안을 다룬다. 그리고 가상훈련에 대해 전문가 경험지식을 별도로 구성하여 평가 분석 시 비교 대상과의 평가 효율성을 높였다. 구성된 전문가 경험지식은 제안된 평가 분석 절차에 따라 학습자의 훈련수행 결과와 정량적으로 비교 분석할 수 있게 했다.
