지구관측데이터 공동활용체계로 GEOSS가 제안되면서 한국에서도 K-GEOSS 개발을 통하여 다양한 방식으로 지구관측데이터의 활용 확산에 참여하고 있다. 본 연구에서는 K-GEOSS 시범서비스로 환경 분야의 생물 종 분포 변화 예측 시나리오를 개발하여 미래 생물 종의 서식지 보호를 위한 지구관측데이터의 효과적 사용 사례를 보여준다. 이러한 시범서비스는 K-DMSS 플랫폼을 이용하여 개발하였으며, 데이터 수집 전처리, 모델 학습 평가, 실제 분포 변화 예측까지 모두 자동화하여 수행한다. 최종단에서 다양한 기후모델 및 기후변화 시나리오에 따른 여러 종류의 예측 결과를 제공함으로써 대체 서식지 보호 및 정책수립을 위한 종합적인 의사결정에 도움을 주도록 하였다. 이와 같은 다양한 종류의 시범서비스 개발 및 지구관측데이터의 공동활용 사례 발굴을 통하여 GEOSS 체계의 정착을 보다 앞당길 수 있다.

국토해양부에서는 2010년 공동구 관리의 필요성을 절감하고 국내 현황을 분석한 결과 공동구 관련 설치 및 유지관리 지침, 지자체별 또는 공공기관별로 법적 장치가 있으나 명확한 규정이 필요하여 공동구 관련법률(국토의 계획 및 이용에 관한 법률)을 제정하였다. 공동구의 관리는 공동구 설계기준, 공동구 시방서를 제정하였으며 설계 및 시공시 각 지자체, 시설관리공단 등에서 활용될 수 있도록 공통되고 일괄된 설치기준이나 유지관리항목이 확립되어 효율적인 제도를 확립하였다. 본 논문은 공동구 설계 항목 및 기준을 고려하여 실무에 적용할 수 있는 공동구 설계 기준이 새로 제정되어 그 내용과 각각의 기준 항목에 대하여 공동구 설계를 통하여 시공이 가능하도록 설명하였다.

This study analyzed the important factors in service quality for public usage of national R&D facilities and equipments, and, using those factors, performed the importance-performance analysis for several national R&D programs in order to examine what service quality factors should be concentrically improved in each programs. Additionally, the in-depth interview with program managers and R&D facility experts was performed to realize the managerial issues subject to the characteristics of programs regarding the national R&D public facility management. As the results, this study made some political suggestions such as the reformation of promoter's role regarding the formulation of the government policy to support those programs. For example, it is more suitable for colleges as the subject of programs to be invested for self-research purpose rather than public usage, for independent corporation to be centered on the more general and common production fields, and for the government R&D agencies on the leading and special technical fields.

Special libraries have purchased materials in only one or two specific subject areas which their mother institutions are concerned. Therefore, special libraries need to develop a well-defined collection development policy for themselves. Special libraries purchase items that are frequently used by their users, and provide access to low-use titles through document delivery services. It is a reasonable solution that the library should Join the cooperative special libraries' association which provides document delivery services in Korea. It is because special libraries' association has achieved document delivery service successfully, when compared with the general(non-special) libraries association. It is expected that special libraries' association can do cooperative acquisition better than other groups.

본 논문은 원격 공동 실험 시스템인 PCS(Platform for Collaborative System) 개발에 관한 연구이다. PCS는 특정 응용 분야를 목적으로 하지 않고, 모든 분야의 공동 실험 시스템을 개발할 수 있는 공동 실험 환경이다. PCS는 공동 실험에 필요한 객체인 통신, 세션, 사용자, 어플리케이션, 미디어, 메시지 객체와 이들에 대한 관리 매커니즘 함수를 가진 관리 객체로 구성된다. 관리 객체는 공동 실험 객체와 이들을 관리하는 오퍼레이션으로 구성되며, 관리 객체 사이의 상호작용을 통하여 제어 정보 및 데이터를 처리한다. 또한, PCS는 공동 실험을 위한 어플리케이션 공유 기술을 통하여 단일 사용자 어플리케이션을 다중 사용자 어플리케이션으로 활용할 수 있도록 하고, 공유 어플리케이션을 통한 원격 기기 제어 기능을 제공한다. PCS 플랫폼은 원격 공동 실험을 위한 환경을 제공하며, 여러 공동 실험 시스템의 하부 구조로 사용될 수 있다.

공동주위의 유동에 대한 연구결과를 보면 개방형 공동(L/D<10)과 밀폐형 공동(L/D>13)으로 구별하는 데 개방형 공동은 앞전에서 발생한 자유전단층이 뒷전 부근에 재부착하여 공동을 완전히 연결하므로, 자유전단층과 외부유동과의 상호작용으로 발생하는 심한 압력변화에 의해 진동현상이 나타나게 된다. 이것은 큰 소음을 유발하고, 구조물의 고장 혹은 파괴의 원인이 되기도 하고, 공력 성능 및 안정성에 해를 주고 민감한 계기를 손상 시킬 수도 있다. 본 논문에서는 공동을 연구하기 위해 EDISON_CFD를 사용하여 공동의 시뮬레이션하기 위해 격자를 구성하고 세장비를 각각 1/5, 1/3, 1/2, 1, 2, 5 로 변화를 주어 M=1.5 일 때 밀도, 압력, 마하수와 유동구조를 세장비에 따라 결과를 비교, 분석한다.

Traditional models for categorizing researcher types have mostly utilized research output metrics. This study proposes a new model that classifies researchers based on the characteristics of research collaboration. The model uses only research collaboration indicators and does not rely on citation data, taking into account that citation impact is related to collaborative research. The model categorizes researchers into four types based on their collaborative research pattern and scope: Sparse & Wide (SW) type, Dense & Wide (DW) type, Dense & Narrow (DN) type, Sparse & Narrow (SN) type. When applied to the quantum metrology field, the proposed model was statistically verified to show differences in citation indicators and co-author network indicators according to the classified researcher types. The proposed researcher type classification model does not require citation information. Therefore, it is expected to be widely used in research management policies and research support services.

Community psychology, which originated from the United States, has made significant progress in many countries over the past 50 years, but it is still an unfamiliar field in Korea. The purpose of this paper is to introduce the core concepts of community psychology and to increase the understanding of community psychology and highlight its practicality and importance. This paper introduces the core concepts of community psychology, including a shift in perspective, first-order and second-order change, ecological level of analysis, and action. It also considers how these core concepts can be utilized and which direction they can provide for the Korean society. Ultimately, the goal is to promote public awareness of community psychology, expand the scope of psychology in Korea, and make a positive contribution to solve social issues in the Koream society.

In this study, the effect of repeated traffic vibration on the long-term stability of mine openings is analyzed for re-utilization of abandoned mine galleries. The research mine in this study is an underground limestone mine which is developed by room-and-pillar mining method, and a dynamic numerical analysis is performed assuming that the research mine will be utilized as a logistics warehouse. The actual traffic vibration generated by the mining vehicles is measured directly, and its waveform is used as input data for dynamic numerical analysis, As a results of dynamic numerical analysis, after 20,000 repetitions of traffic vibration, the mine openings is analyzed to be stable, but an increase in the maximum principal stress and an additional area of plastic zone are observed in the analysis section. As shown in the changes of displacement, volumetric strain, and maximum principal stress which are measured at the mine opening walls. It is confirmed that if the repeated traffic vibration is continuously applied, the instability of the mine openings can be increased. Authors expect that the results of this study can be used as a reference for basic study on utilization of abandoned mine.

The purpose of this study was to investigate students' perception of Advanced Placement Program. Participations of this study were 1144 students from 14 science high schools. The results showed as follows. First, students perceived positively regarding AP program and were willing to take AP courses because of interesting and challenging in academic area which is provided by AP courses. Secondly, many students would like to take AP courses in Differential and Integral Calculus 1, General Physics I, General Chemistry I and General Biology. Also, they would like to take AP courses in first term as a mandatory subjects. Third, responses perceived that AP courses were challenging, difficult, and of high quality. Finally, students perceived the benefit of AP courses in earing college credit. However, 35% of responses wished to receive an exemption for all AP courses. Also, they wished to have dual-major or participate in students exchange program as a benefit of AP program. Implications of the study were discussed in depth based on the results.
