중소기업중앙회 등 33개 경제단체 및 38개 발전 에너지기업은 지난 6월 16일 정부가 최근 발표한 2030년 온실가스 감축 목표에 대한 공동의견서를 발표했습니다. 경제계는 발표문에서 "정부가 본실가스 감축 목표를 과도하게 실정해 우리 기업의 경쟁력이 약해지고 산업공동화 현상을 초래할 수 있다"며 "2030년 온실가스 감축 목표치를 재조정해야 한다"고 주장했습니다. 7 8월 골판지포장물류지에서는 최근 정부가 제시한 2030년 온실가스 감축 목표안과 감축이유에 대해 자세히 살펴보도록 하겠습니다.

Hydraulic performance and cavitation characteristics of fuel pump in turbo-pump were studied experimentally. The fuel pump has a centrifugal impeller with a separate inducer. In this paper, flow characteristics of inducer and impeller was experimentally investigated separately and together. Especially static pressure distribution of Inducer was examined in non-cavitation and cavitation conditions.

어촌은 바다, 섬, 자연경관, 해양레저, 수산자원 등의 다양한 해양 관광자원을 보유하고 있어 성장 잠재력이 풍부하나, 이를 통해 성장할 수 있는 기본적 인프라 및 콘텐츠가 절대적으로 부족한 실정이다. 또한 수산업 침체와 어촌인구 감소 및 고령화로 어촌 공동화 현상이 심화되고 있으며, 정주환경 저하 등 삶의 질 전반에 걸쳐 낙후된 상태이다. 본 연구에서는 어촌마을의 자원활용과 자원 간의 연계를 촉진시킴과 동시에 정주기능, 생산기능의 활성화를 도모할 수 있는 소득증대 방안을 마련하고자 함

There has been the increasing concern with the safety of seven major urban infrastructure such as road, electricity, water supply, sewerage and so on due to urban expansion and new town development. However, high technology development for the common duct which can be an alternative for the safety issue has not been completed due to the law of the national security area. Existing management method of the common duct by people could not respond to the urgent accidents adequately and immediately since it is impossible for us to get access to that in case of fire or gas leak. This study suggests to the method of installing monitoring devices and processing CCTV images with a water supply in a TestLab(a variety of the USN(Ubiquitous Sensor Network) equipment was tested in the TestLab in KICT). The suggested management method of common duct facilities make it possible to do real-time monitoring and prompt access and response to an accident inside the common duct.

Korean medical libraries have made interlibrary loan active under the korean medical library association since 1969, the sharing acquisition of journals has not been peformed efficiently in the absence of a bibliographic control institute. The medical library of seoul national medical university which is designated to a medical professional information center by korea education academy information developed MEDLIS linking the union catalog and interlibrary loan system and has been operating it in cooperation with the korean medical library association. Two types of questionaries were sent to 350 medical researchers and 160 medical librarians to investigate the realities of domestic and foreign medical information institutes, develop sharing systems and find a solution for sharing systems. Also, some analyses for the recent state of duplicate subscriptions, interlibrary loan, demands for system operations un the basis of the statistics of MEDLIS users were made. The result showed that medical researchers and medical librarians are affirmative for MEDLIS, users need a convenient interlibrary loan system and medical librarians agree to activate interlibrary loan. It also showed that sharing acquisition of journals seemed to be realizable for medical librarians, although there was no intention to improve the centralization of interlibrary loan among them. From the findings, a plan for sharing acquisition of journals established by the sharing acquisition committee under korea medical libraries society and national 8 local centers to play a key role in it was made. Also, a proposal for the establishment of an information center for controlling korean medical bibliographies was suggested. This system will be expected to contribute to make users to acquire materials more effectively and save the national budget.

Online communities have become playgrounds for enjoyment and political public spheres as well as have been vitalized by participation of diverse users, which shows that users of online communities experience participatory democracy and new subjects who project the politic of everyday life eventually. The purpose of the study is to examine that how phenomenon from above have been revealed in the academic discourses and seek the ways for development of the theory and methodology of community media research. To do this, I analyze that features and tendencies of academic discourses which have historically been accumulated through applying method of meta-analysis into topics, methods, and issues in the precedence studies. Data is centered on Journals of the Korean Society for Journalism and communication Studies, Korean Association for Broadcasting and Telecommunication studies, Korean Association for Communication and Information studies, and the Cybercommunication Academic Society. The reason why I choose these journals is that they have a long history of the publication compared to other journals, thus, I can collect various related articles. Total of 53 Samples are selected after input keywords '공동체' and 'Community'. This study makes a contribution by offering the preliminary data in order to seek the ways for revitalization of local communities and for the future theories and methodologies of community media through researching on precedence studies having piled from 2001 when the first article about community media was published to November 2016.

The inter­relationship of Korea southeast region community related to a mask dramas in depth. The Folk mask dramas are, for traditional community members to live well and enjoy cultural practices in society. Even if a mask drama would be performed in the 21st century, it would be the one of traditional society. It shows the life of traditional society and proposes the issue of traditional society. The thing is handed down well with technology of a mask drama assigned as intangible cultural asset. The Korea southeast region, Kyongsang Provinces, or Yeongnam area has been handed down several kind of mask dramas. These are Byeolsingut Talnori with religious, the Ogwangdae of wandering play team, the Ogwangdae of local residents, and the Dulnorum of local residents. The mask dramas of Korea southeast region are specified as intangible cultural asset, many traditional mask play were restored. The restoring is imitation. These things are difficult to assigned as the intangible cultural asset. But though it is the imitation of the mask dramas, it is culture phenomenon. So we need to make the fostering system.

Underground utility tunnels are spaces densely packed with various infrastructure facilities, such as power, telecommunications, and water supply and drainage systems, making internal environment management crucial. An investigation into accident cases and on-site demands in these tunnels revealed that while fires and floods are the most common types of incidents, the demand for real-time condensation prevention and response is frequent according to on-site managers. Condensation occurs due to the difference in humidity and temperature between the inside and outside of the tunnel. Frequent or prolonged condensation can lead to metal pipe corrosion, electrical failures, and reduced equipment lifespan. Therefore, this study developed a control algorithm and monitoring system to prevent condensation in underground utility tunnels. The proposed control algorithm estimates the likelihood of condensation in real-time based on the measured temperature and humidity and suggests appropriate responses for each stage to the managers. Finally, a practical condensation prevention monitoring system was built based on the developed algorithm, verifying the feasibility and applicability of this technology in the field.
