The purpose of this study was to examine the factors associated with adolescents' attitude toward volunteer activities. Analyses of data provided by 450 adolescents attending secondary schools in Gyeongnam Province suggested the following results. First, adolescents' attitude toward volunteer activities differed by gender, religion, and academic grades. Adolescents who were girls, who had religions, and whose academic grades were higher showed higher levels of positive attitude toward volunteer activities than their counterparts who were boys, who did not have religion and whose academic standing was lower. Second, adolescents' attitude toward volunteer activities significantly differed by the family factor. To be specific, parental attention, parental support and family's participation in volunteer work made differences to the adolescents' attitude toward volunteer activities. Third, the adolescents took significantly different attitudes toward voluntary activities according to the school factor. Significant differences were found according to attention and support from teachers. The students whose teachers had more interest in voluntary service and whose teachers offered more aid took a more positive attitude to voluntary service. Forth, some of the personal, family, and school factors were associated with adolescents' attitude toward volunteer activities. Among the personal factors, gender, religion, academic standing, and morality were associated with dolescents' attitude toward volunteer activities. Those who were girls, who were religious, whose academic standing was higher, and who were more moral took a more positive attitude toward volunteer activities. Among family and school factors, parental attention/support and attention and support from teachers affected the voluntary service attitude of the adolescents. The students whose parents had more interest and gave more support and whose teachers showed more interest and offered more support took a more positive attitude toward volunteer activities. Therefore parental attention and support were identified as the variable to make the best prediction of the adolescents' positive attitude toward volunteer activities.

소프트웨어 프로젝트가 대규모화되고 복잡해짐에 따라 체계적인 품질보증이 더욱 필요해지고 있다. 고품질의 소프트웨어를 개발하기 위해서는 작업산출물(work product)에 대한 품질보증뿐 아니라 개발 프로세스(process)에 대한 품질보증 활동을 동시에 수행해야만 목표하는 품질에 접근할 수 있다. 그러나 소프트웨어 품질보증은 다양한 품질특성이나 개발 주체간의 시각 차이에 따라 달라지는 가변성을 지니고 있어 품질보증에 적지 않은 어려움이 내재되어있다. 이러한 품질보증의 어려움이 소프트웨어 품질을 저해하는 원인으로 작용하여 기업의 품질 경쟁력을 떨어뜨리고 있다. 본 연구는 이러한 품질보증 활동의 어려움을 해결하고 나아가 품질향상을 달성하기 위한 방법을 개발하고자 하였다. 품질향상을 위해서 품질보증 활동을 보다 계획적이고 체계적으로 수행하기 위한 SQA(Software Quality Assurance) 방법론을 개발하였다. 일반적으로 방법론이란 모든 프로젝트에 그대로 적용하기란 어렵다. SQA 방법론 또한 프로젝트의 특성이나 조직 특성에 따라 적절히 커스터마이징(Customizing)되어 사용하여야만 효과성을 제고할 수 있다. 그리하여 본 SQA 방법론에서도 품질보증활동을 체계적으로 지원하기 위해 수행되어야할 품질보증 태스크가 리파지토리로 구성되어 있다. 프로젝트 특성 둥에 따라 필요한 품질보증 태스크를 이 리파지토리로부터 선정하여 활용할 수 있게 된다. 마지막으로 프로젝트 특성 등에 따라 필요한 품질보증 활동을 커스터마이징하기 위한 전문가시스템 접근방법을 제시한다.

This paper introduces a relative comparative advantage index and a composite concentration index of university research activity in science and technology. Three hypotheses were tested regarding differences of degree of concentration based on the size of government R&D fund, location of university, and source of foundation, respectively. T-test results imply that there are significant differences of concentration based on the size of R&D fund and source of foundation, while location of university does not show a significant difference. The paper generally suggests that the lesser size of government R&D fund would lead higher level of concentration, and public funded universities tend to maintain far higher concentration ratio. The paper contributes by introducing relevant indexes for analyzing university research competence, concentration and competitiveness, and hence by proposing policy direction and implication for university competitiveness policy.

Developing new technologies and launching new products require a huge sum of money for Research and Development, and there is also market uncertainty. Comparing to advanced countries' companies, Korea's exporting companies have less investment cost in size for R&D and insufficient technology assets accumulated. Therefore, through the open innovation, they should use external technology and enhance the efficiency of the relatively little R&D investment. This paper draws the factors influencing the innovations of Korea's exporting companies, and then it analyses how each innovation influences export performance. First, innovations are devided into two; closed and open innovation. Multiple regression analysis has been done, considering influence factors of innovation such as company's characteristics factors, research's characteristics factors and products characteristics factors to be independent variables, and export performance to be a dependent variable. It shows that firm size and new products launching period have positive effects on each innovation, but research capability and research performance have positive effects only on closed innovation. And open innovation has positive effects on export performance, but closed innovation doesn't have.

Recently, the intensive rainstorm possibly induced by global warming plays a key role on the instability of railway adjacent slopes. The instability of slopes results as covering and loss of railway lines induced by slided soil mass. According to the site investigation on the failed slopes triggered by rainfall, low types of slope failure were observed: shallow, intermediate, gully erosion, and soil-rock interface failures. The observation reveals the different characteristics of slope failure depending on the thickness of soil layer, morphological features of slope, etc. Based upon the observations, flume tests were conducted to analyze the sliding mechanism of each failure. The variables of flume test are soil layer thickness, rainfall intensity, and morphology of slope under the constant condition of the percentage of fine, initial soil moisture content, slope angle and compaction energy. Test results show that shallow failure was mostly observed from the surface of the slope and caused by the soil erosion; in addition, compared to the other types of failure, the occurrence of initial erosion is late, however, the development of erosion is fast. In gully erosion failure, the collected water from the water catchment area helps erosion of the upper soil layer and transfer of residual corestone, which impedes the erosion process once the upper soil layers are eroded and corestone are exposed. The soil-rock interface failure shows the most fast initial erosion process among the failure types. Interestingly, the common feature observed from the different types of failure was the occurrence of the initial deformation near the toe of slopes which implies the existence of surbsurface flow along the downslope direction.

지역에 밀착한 관광이 추진되면서, 관광레크레이션지역의 개발 및 관리운영에 있어서는 시민참여에 의한 자원 및 지역만들기가 상당히 중요한 이슈로 떠오르고 있다. 그러나 국내에서는 이러한 시민참여 활동의 역사가 짧고, 특히 관광과 관련해서는 아직 시민참여 활동이 본격화 되고 있지 못해, 그의 구체적인 활동범위 및 방향 등이 정리되지 못한 상태에 있다. 본 연구는 관광레크레이션지역에 있어서 시민참여의 활동범위와 그 추진방향에 대한 틀을 마련하기 위한 기초연구로서, 일본국영공원을 대상으로, 관광레크레이션지역에서의 시민참여 활동의 실태와 그 특성을 분석한 것이다. 연구결과 국영공원의 시민참여 활동은 테마 자원과 시설을 중심으로 매우 세분화되고 있고, 그 범위는 단순한 안내 및 관리가능을 넘어 연구회 및 학습회 등을 통해 보다 조직적, 능동적으로 참여함으로서 개발계획과 평가단계까지 그 영역이 확대되고 있는 것으로 나타난다. 또한 이들의 활동은 대상지 내에 국한되지 않고, 역 외의 유관단체와 연계해 하나의 교류네트워크의 축을 형성함으로써 자원자체의 활성화에도 크게 기여하는 것으로 나타난다.

This paper develops a dynamic structural equation model, which captures relationships among socio-demographics, activity participation(i.e., time use) and travel behavior in consideration with time variation effects. The data used in developing the model are two waves(the year 1991 and 1992) from Puget Sound Transportation Panel (PSTP). which is surveyed in Puget Sound Region in United States. The PSTP is widely used in transportation behavior analysis and includes various information of traveler's socio-economic, travel patterns, and activity participation. In the model, we use 10 endogenous variables including activity participations and travel behaviors and 10 exogenous variables composed of time variant and invariant traveler's socio-demographic variables. The empirical model shows that strong relationships exist not only between socio-demographics and travel behavior, but between waves. We also confirm needs of panel data set to identify and understand time variation effects and travel behaviors.

Activity materials in textbook could facilitate students' oriented self-help learning. The purpose of this paper is to find out characteristics of activity materials in the housing area of middle school Technology and Home Economics and teacher's perception of them. The data were collected from 253 middle school teachers who had ever taught the housing unit in any of 6 textbooks. The results showed that the number of activity materials were differed by the characteristics of the materials such as type of materials, feature of non sentence materials, and type of activity, depend on authors as well as textbooks. In general, teachers interests in the materials were higher than those of students even the trends of the interests were the same. Adequacy of activity contents and related knowledge of teachers were higher than adequacy of level. Teachers thought time and extra search beyond class were barrier to full the interests of students. Further research is suggested to find out whether higher interests in the materials are related to the higher activating rate of them.
