불행하게도 우리 국토는 기후 재난을 막을 수 있는 물 관리 여건이 매우 취약하다. 장마철에는 폭우로 인해 물난리를 겪고, 가뭄에는 물 한 방울이 아쉽다. 여기에 대형 자연호가 전무하여 장마에 집중되는 비를 모아둘 물그릇이 크게 부족하다. 한반도에 도래하는 기후변화는 이처럼 취약한 우리의 물 관리 여건을 더욱 심각한 상태로 몰아가고 있다. 폭우와 가뭄은 점점 강해지고 있으며, 그 피해는 연간 수조원에 달하고 있다. 역사와 전통을 가진 가뭄과 홍수의 나라이자 태생적 물그릇 부족국가에서 다가오는 기후 변화는 결코 방치될 수 없는 시급한 현안이다. 물그릇을 키우고 국토의 혈관이나 다름없는 강의 기능을 살려 기후재난을 최소화하는 물관리의 대변화가 절실하다. 이 글에서 4대강 살리기의 필요성과 찬반 논란의 핵심 쟁점에 관해 논의하고자 한다.

The Korean Government recognized that the importance of spatial information market is promoting Korean Land Spatialization Program(KLSP) to commercialize and practice of the technology. For achieve this purpose, KLSP is planning to build test-bed for field test, integration, display of outcomes. The most important problem in this process is reasonable decision of location. In this paper, the subject is to find how to decide efficiently in locating facilities to test Geospatial information technology like KLSP Test-bed. Consequently, we look over some cases of the inside and outside of the country, and analyze property of outcomes to apply the test-bed. And then we find assessment items for locating.

The present study aims at developing a policy framework for the long-term preservation of authentic digital records. To accomplish this, the study analyzed the main research outcomes from InterPARES(International Research on Permanent Authentic Records in Electronic System: IP). It has (1) selected major outcomes from IP project, (2) disassemble principles and guidelines suggested by IP into individual concepts and components, (3) rearranged them into a conceptual framework, which has been used as a basis for the policy framework, and finally (4) developed a policy framework for the long-term preservation of authentic digital records. The policy framework suggested here could serve as a basis for either establishing national or institutional policy or developing standards and guidelines for long-term preservation of authentic digital records.

This study conducted a questionnaire survey on SNS users who are conducting K-POP record collection activities using SNS and verified factors affecting the intention to continue K-POP record collection activities. The main methods of analysis were exploratory factor analysis, confirmatory factor analysis, correlation analysis, and path analysis using SPSS 21.0 program and AMOS 21.0 program. The results are summarized as follows. First, compatibility for K-POP record collection activities through SNS has a positive effect on perceived usefulness, and observability also has a positive effect on perceived usefulness and perceived ease of use. Second, perceived ease of use for K-POP records collection using SNS has a positive effect on perceived usefulness. Third, perceived usefulness and perceived ease of use for K-POP records collection using SNS have a positive effect on continuous intention of K-POP records collection activity through SNS. As a result of this study, it suggests that the intention to continue the collection activities of K-POP records using SNS can be explained through the integration of innovation diffusion theory and technology acceptance model.

In this study, heat and crack resistance of natural rubber (NR) compounds was evaluated. To prevent the effects of the crosslinking system, a conventional vulcanization system was selected, where the accelerator/sulfur ratio was fixed to 0.25. Vulcanizates containing phenylenediamine showed high tensile strength and tear strength compared to other vulcanizates because phenylenediamine can cause additional crosslinking and high dispersion In the vulcanizates. In the pure shear test, vulcanizates containing phenylenediamine showed an excellent tearing energy which was due to the irregular crack path, and showed excellent heat and crack resistance which was also due to the good dispersity of antioxidant and additional crosslinks in the rubbber vulcanizates.

DSM and orthoimage, which are representative results of UAV photogrammetry, are high-quality spatial information data and are widely used in various fields of spatial information industry in recent years. However, the UAV photogrammetry has a problem that the quality of the output of the UAV deteriorates due to the altitude of the UAV, the camera calibration, the weather conditions at the time of shooting, the performance of the GPS / IMU and the number of the ground reference points. The purpose of this study is to analyze the location accuracy of unmanned aerial photogrammetry according to the change of the number if ground control points. Experiments were made with fixed wing, and the shooting altitude was set at 130m and 260m. The number of ground reference points used was 9, 8, 5, and 4, respectively. Ten checkpoints were used. XY RMSE for orthoimage and Z RMSE for DSM were compared and analyzed. In addition, the resolution of the orthoimage was determined to affect the judgment of the operator in the verification of the planimetric position accuracy, and the visual resolution was analyzed using the Siemens star target. As a result of the analysis, the variation of the vertical position accuracy is larger than the variation of the planimetric position accuracy when the number of the ground reference points are different. Also The higher the flying height, the greater the effect of change of ground control points on position accuracy.

Open Access (OA) policy to scholarly publications from publicly funded research goes toward making a law at the national level. The purpose of this study is to suggest the ways of improving laws and regulations for OA of scientific publications from national R&D projects. For that purpose, this study analyzed cases of USA, Spain, Germany, and France which have already legislated OA related laws and regulations. Based on the results, the followings were proposed: 1) to unify definitions of research outcomes and to include research papers to the definition. 2) to strengthen OA obligations by amending "Act On The Performance Evaluation And Management Of National Research And Development Projects, Etc." by to specify related articles about submission, making public, enrolling, deposition, and possession of research papers, and 3) to revise administrative rules and "Regulations on Management of National Research and Development Projects" which common to all administrative according to amending the law.
