Since the ITS project of Gwacheon city has been implemented in 1998, feasibility analysis for various ITS projects has been conducted in quantitative and qualitative aspects. However, ITS operation manual that describes the universal standards comprehensive methodology for survey and analysis for the qualitative effects of the ITS. Although it its difficult to measure the qualitative elements, the effectiveness and achievement of ITS project can be directly evaluated from the user survey. A comprehensive methodology proposed in this paper includes the design and implementation of the qualitative survey, the procedure of data analysis, the evaluation, and proposing the enhancements. The proposed methodology that take both quantitative and qualitative aspects into account, therefore, can lead the accurate and effective assessment of ITS projects.

A survey was conducted to analyze the perceptions related to research performance evaluation from 2,618 professors. The survey is to find out the perception about two parts. One is a survey of professors' perceptions about the faculty performance evaluation, which is currently being conducted at each university. The other is that we analyzed the perception of the introduction of qualitative performance evaluation indicators, an alternative to the quantitative performance evaluation. As a result, we confirmed followings. Quantitative research performance evaluation is carried out in most universities. Research performance evaluation is not appropriate for a department or research field. And an extension of the evaluation period is required. Quantitative evaluation have a negative impact on the academic community. Quantitative evaluation needs to be improved. As regard to the introduction of the qualitative evaluation, we confirmed that professors perceived that qualitative evaluation is necessary to evaluate research performance, and they also have negative opinions about introduction of qualitative evaluation.

The purpose of this study was to investigate the relation between and subjective instability pain behavior (SIPB) and physical instability test(PIT) according to the presence of characteristic past histories(CPH) in people with chronic low back pain(CLBP). Forty CLBP subjects participated in this study. The presence of four characteristics past histories(long term history, traumatic experience, sports activities, neurologic sign) were examined. According to presence number(PN) of CPH, subjects were divided into 5 groups[group 1(PN:0): n=8, group 2(PN:1): n=8, group 3(PN:2): n=8, group 4(PN:3): n=8, group 5(PN:4): n=8]. After 16 items were examined for the SIPBs, then Seven PITs were conducted, and the results were scored. The SIPBs and PITs were compared according to the presence numbers of CPH, and the relation between them was analyzed. There was a significant difference(p<.05) in both SIPB scores and PIT scores in the comparison of groups according to the presence number of CPH. There was high positive correlation between the presence numbers of CPH and SIPB score(r=.819, p=.000) and PIT score(r=.606, p=.000). Also, there was a correlation between SIPB score and PIT score(r=.571, p=.000). Based on the findings in the present study, the presence of three or more CPH in people with CLBP may be a useful variable in the diagnosis of lumbar instability. The combined findings of the three variables such as CPH, SIPB, and PIT can improve the accuracy of lumbar instability diagnosis.

우리나라 전력기술 수준의 평가는 전력기술 중장기 발전계획에 대한 기초자료로서 전력인프라의 투자, 연구개발정책의 수립, 예산배분의 기된 데이터로서 활용되고 있지만, 대부분의 기술수준 평가방법이 전문가 설문조사에 의한 정성적 평가에 그치고 있어 산업 현장의 데이터가 반영되는 데는 미흡한 점이 있었다. 된 논문에서는 이러한 단점을 보완하기 위해 전력기술전반의 수준 평가를 전력산업 각 부분의 계량지표를 관간으로 산출하는 방법에 의한 계량적인 기술평가를 시도하였다. 이 정량적 평가결과를 전문가의 정성적 평가결과 및 과학기술부 조사결과와 대비함으로써 그 차이를 논하고 향후 해석적인 기술평가를 위한 발전방향을 제시하였다.

본 연구에서는 포레스터 그룹에서 제시한 커뮤니티 활용그룹을 중심으로, 실험 참여자 12명을 섭외하여 사용자 조사를 진행한후, 정성적 분석을 진행하였다. 그 과정에서 슈나이더만의 네트웍을 활용하는 4가지 주요 행동들을 대입하여 이에 해당하는 행위들을 파악할 수 있도록 프레임웍을 갖추었다. 결과로 이들의 행동들이 6가지로 차이를 분명하게 나타내고 있으며 이를 통해 사용자 연구에서의 정성적 분석이 구체적 근거를 가질 수 있음을 검증하였다. 본 논문은 사용자 조사를 통해 연구를 진행하는 과정에서 섭외된 사용자의 객관적 검증을 위해 연구자의 성향을 조사할 수 있는 프레임웍을 반영하여 신뢰도를 높일 수 있음을 케이스 스터디로 연구하였다.

PFI(Private Finance Initiative) Project is carried to expand infrastructure effectively through participation of private investment. From the year 2005, the range is expanded not only industrial infrastructure such as made road, harbors and so on but living infrastructure such as school facilities, environmental facilities. For this reason BTL(Build-Transfer-Lease) system is mainly used in new private finance initiative project but in existing private finance initiative project BTO(Build-Transfer-Operate) system was used. BTL system is operated to judge fitness of private investment and classified into quantitative VFM(Value for Money) and qualitative VFM. In this research the estimation item of qualitative VFM which is hard to deduce the effect is created and after surveying of questionnaire in target of experts, relative importance and weight is established with AHP(Analytic Hierarchy Process). By estimating efficiency and benefit of quantitative VFM and qualitative VFM aspect effectively it is expected to support a rational making decision for operating BTL.

Aging is rapidly progressing around the world. This study explore and propose a qualitative user research method to specifically understand the needs and desires of the elderly based on a human-centered design philosophy for design targeting the increasing elderly. In particular, the purpose of this study is to propose a user research method that can be easily used when designing products used by the elderly in the actual design site. For this purpose, this study examined the use and implications of using shadowing, interviews, and direct experience while actually proceeding with the walking stick design. The shadowing was organized through the AEIOU frame, and the interview was conducted by adding a significance category to reflect the recent trend of the silver generation. For the direct experience, design implications were derived by setting up four user behavior scenarios, each indoors and outdoors, and experiencing them directly by designers. This study is expected to be an important user research guideline in the current situation where the demand for design for the elderly is diversifying and increasing.

The application of a multiple rock classification method, which is a generalization of a binary rock classification, is studied in this paper. In particular, this paper shows how to incorporate qualitative data through a case study. The method suggested in this paper can be effectively used for a systematic multiple rock classification such as RMR system developed by Bieniawski. It will be very useful for rock classifications. In addition, it is known that the expected cost of errors can be atopted to indicate how well a investigation plan is made.
