Without much communication, large-scale surveys of public knowledge of, and attitudes to, science (quantitative PUS) and case-study analyses of the public's understandings of science in particular (constructivist PUS) have dominated in the public understanding of science (PUS) area. Not only methodological preference but also a strong antipathy against value-orientations that each approach presumed to have and support has been barriers for quantitative PUS and constructivist PUS to benefit each other. In order to overcome such barriers, this paper demonstrates that value orientations guiding quantitative PUS have been much more diverse than what constructivist PUS researchers might think, and that quantitative PUS has indeed yielded the results consistent with and complementary to constructivist PUS. Finally this paper proposes that (1)quantitative PUS should test propositions provided by constructivist PUS, so that it can contribute much to the construction of more generalizable PUS theories and policies, and (2)constructivist PUS uses the outcome of quantitative PUS to develop more complex case studies which consider heterogeneous publics, trends of public evaluations of science, and how public attitudes to science in the abstract and public attitudes to science in particular in a specific context have effect on each other.

본 연구에서는 횡단면 즉 지방자치단체별로 "고정된 효과"를 가지고 있다는 전제하에 시의 공무원 정원을 산정하였다. 본 연구에서 주장하는 시의 공무원 정원은 시 공무원 1인당 업무량에 기준한 적정정원에 대한 산출은 아니나 도시형태별로 - 일반시와 도농복합행태의 시 - 동종 시가 평균적으로 고용하고 있는 현정원에 가까운 평균 인력규모를 타단체와의 비교를 통하여 평균적인 추세를 파악했다는 점에서 의의 있는 일이다. 그러나 공무원 정원산정의 거시적 모델을 학문적으로 논의하는 것은 가능할 지 모르지만 계량적 방법의 한계가 있기 때문에 이를 현실에 적용하는 것은 정치적.사회적으로 타당성에 한계가 있다.성에 한계가 있다.

Simulation은 진실로 대단히 편리한 도구이다. 그러나 절대로 이것이 "만병통치"는 되지못한다. Simulation은 원래 통계학적인 근사치를 구하는 방법이고 적정정책이 직접적인 해로 나오는 것이 아니라 단지 몇개의 대안을 비교하는 데 그친다. 또한 Simulation이란 어디까지나 계량적인 기법이기 때문에 모든것이 수치로 나타나고, 숫자로 나타나지 않는 인과관계나, 또는 modeling단계에서 빠뜨린 부분에 대한 영향은 알 수가 없다. 그럼에도 불구하고 Simulation는 운영연구에 있어서 대단히 편리한 도구이고 다른 방법으로 해결할 수가 없는 많은 운영문제에 있어, 없어서는 안될 중요한 기법이다. 중요한 기법이다.

This study is concerned with providing a reliable procedure of calibrating a set of places specific distance parameters and with applying it to U.S. inter-State migration flows between 1985 and 1900. It attempts to conform to recent advances in quantitative geography that are characterized by an integration of ESDA(exploratory spatial data analysis) and local statistics. ESDA aims to detect the spatial clustering and heterogeneity by visualizing and exploring spatial patterns. A local statistic is defined as a statistically processed value given to each location as opposed to a global statistic that only captures an average trend across a whole study region. Whereas a global distance parameter estimates an averaged level of the friction of distance, place-specific distance parameters calibrate spatially varying effects of distance. It is presented that a poisson regression with an adequately specified design matrix yields a set of either origin-or destination-specific distance parameters. A case study demonstrates that the proposed model is a reliable device of measuring a spatial dimension of migration, and that place-specific distance parameters are spatially heterogeneous as well as spatially clustered.

This paper intends to provide applied economists which study the effects of research and development with valuable information on econometric model selection. It includes extensive discussion on econometric models which have been applied for the study on the relationship between research and development and productivity. In particular, it compares various stochastic production frontier models which have been developed recently. The discussion decomposes them into models with scaling property and the ones with nonscaling property as well as models with monotonic and nonmonotonic relationships between research and development and productivity. Finally, this paper applies the models to two different panel data sets (firm level data and country level data) and compare estimation results from competing econometric models.

Research methods is an integral component of a field and plays a crucial role for the development of a field. Three areas are explored to assess research methods in Korean library and information science (US) graduate programs: (1) comparison of research methods'courses across Korean LIS graduate programs; (2) content analysis of the trend of research methods education; (3) comparison of research methods'courses between the U.S. and Korean library and information science graduate programs.

Since computer integrated technology was introduced to the field of education, it has offered an expanding range of interactive possibilities which are remarkably powerful and helpful for the learners, especially constructing the cyber learning environments. Interactivity, the critical element in cyber learning, is categorized into three dimensions: student-to-contents, student-to-student and student-to-instructors. Six surrogate variables are introduced, and two quantitative model are developed for evaluating the degree of interactivity. The first model, which is called Data Envelopment Analysis model, is a linear programming based technique for measuring the relative performance of organizational units where the presence of multiple inputs and outputs makes comparison difficult. DEA model allows each unit to adopt a set of weight that shows it in the most favorable light in comparison to the other unit. The Second model employes the weighted average of standardized input variables for evaluation. Actual data have been collected from the Cyber IT university and these two models are applied for comparison. The analysis shows that the results from these two models are very much similar to each other, and are highly correlated to the level of class satisfaction.

When IoT is applied to various research experiment fields such as physics, pharmacy, biology and medicine, it can increase the safety and convenience of researchers by intelligently monitoring and controlling research equipment and environment with various sensors and devices. For accurate and convenient record management and the research history and the basis but also for the reverse tracking, real-time reagent measurement and registration should be provided as a research support automation services. Currently, existing methods of reagent management are operated by computerized method, but reagent registration and management are not automated. And also record is managed manually, there are many hassles and problems such as a record error and too much time required for quantification and registration for many reagents. In this paper, we study a real time reagent measuring and registration method based on IoT to resolve the problems aforementioned, by the information of the reagent acquired by image recognition and NFC method.

천연 및 저농축 우라늄 가공시설은 취급하는 핵 물질의 민감도가 고농축 우라늄이나 플루토늄에 비하여 상대적으로 낮기 때문에 원자력발전소, 연구용 원자로 등과 같은 시설보다 국제원자력기구의 보장조치 적용 방법이 단순하다고 생각하기 쉽다. 그러나 가공시설은 취급되는 핵 물질이 UF6, 우라늄 분말, 소결체 등과 같이 계량하기 쉽지 않는 형태로 존재하는 중량시설(bulk handling facility)이기 때문에 오히려 핵연료집합체 만이 존재하는 계수시설( item facility) 보다 더 다양하고 정밀한 계량방법이 적용되고 있다. 이 때문에 국제원자력기구에서는 일반 원자력발전소의 4-5배에 달하는 사찰량을 가공시설에 투입하고 있으며, 동 시설에 대한 보다 효과적이고 효율적인 사찰방법을 개발하고 있다.
