  • Common structural rule (CSR) doesn' t provide any other specific regulations for permanent means of access (PMA) platform structure in a cargo oil tank. The PMA platform is recommended to comply with scantling requirement of local support member. However, it leads to too conservative scantlings compared with actual loads imposed on the platform. This paper proposes a strength assessment procedure for the PMA structure based on a nonlinear ultimate strength. The ultimate strength is evaluated in a sufficiently conservative way. The first linear buckling mode is used as an initial imperfection shape and its magnitude is determined using the definitions of DNV PULS. Since the same imperfection mode as the failure mode of the ultimate limit state is assumed, it can accelerate the failure. Au ultimate strength capacity curve obtained from a series of nonlinear FE analysis is compared with actual stresses calculated by CSR cargo hold analysis.

  • Innovation plays a large role in green growth. While it is a widely accepted view that, without innovation, it would be very difficult and costly to address major environmental issues, innovation itself tends to be constrained by limited access to eco-financing and is inherently risky, often requiring a long-term horizon. Although global consensus is more or less established as to the urgency and necessity of accelerating green innovation, the quality and quantity of financing in this area is largely insufficient, with increasing funding gaps in many countries. A new financial mechanism is urgently needed in order to re-orient financial flow and enable innovators to overcome the valleys of death that occur throughout the innovation cycle. A number of different modalities exist in financing the commercialisation of eco-innovation. Existing mechanisms have not been as successful as expected, revealing critical limits to furthering certain types of projects that are essential for economic and environmental progress. Experts' estimations have shown that the funding gap will widen in the coming years as demand for clean energy and green infrastructure rises, and as green technologies and innovation develop faster than the market for it can develop. Against this backdrop, the main purpose of this research is threefold: to identify issues and problems regarding current means of funding for eco-innovation and green projects; to provide insight into securing longterm green financing by looking at European cases; and ultimately to suggest policy implications for designing and implementing eco-specific financial instruments, focusing on governments' roles in sustainable financing for eco-innovation. This study analyses different models of financing mechanisms, a mix of public and private funds, in view of suggesting conditions for the sustainable financing of green projects, especially for large-scale high-risk projects. Based on the findings from the analyses of mechanisms and the shortcomings of the existing funding modalities, this study ultimately suggests policy implications for effectively supporting the commercialisation of eco-innovation.

  • 오늘날 인터넷과 전자출판 기술의 발달로 전자자원에 대한 이용이 매우 활발히 이루어지면서 연구자들 학술활동의 핵심 정보자원인 학술지가 전자원문 형태로 활발히 이용되고 있다. 이는 한정된 도서관 자료수집 예산 속에서 물리적인 자료 소장 공간의 부족, 이용의 편리성을 고려한 점을 원인으로 볼 수 있다. 그러나 현실적으로 전자자원은 소유보다는 접근의 개념에서 출판사 및 정보제공기관에 의해 이용권한이 매우 제한적이며, 구독기간이 만료되면 더 이상 이용하기 어렵다는 한계가 있다. 이에 전세계적으로 전자자원을 통한 이용의 편리성을 도모하는 한편, 인쇄자원에 대한 분담 수집 및 공동 보존을 하기 위한 움직임이 일어나고 있다. 본 연구에서는 국내외 도서관에서 해외인쇄학술지 수집 및 유통현황을 분석하고 국내에서 수집되고 있는 인쇄학술지를 대상으로 국내 기관유형별 지역분포, 중복수집기관분포, 주제분포 현황을 살펴보았다. 그리고 협업기반의 전략적 자원개발을 추진하기 위한 고려사항을 논의하였다. 이는 국가차원에서 자원에 대한 중복을 최소화함과 동시에 학술지의 가용성을 극대화할 수 있는 공유협력기반의 자원 개발을 추진하기 위함이었다.

  • 과학기술정보자원은 모든 연구개발의 동력에 해당되므로, 선진국들은 폭발적으로 늘어나는 자국 국민들의 과학기술정보자원의 수요에 적극 대응하고자 효율적인 지식정보인프라 구축 차원에서 국가과학도서관의 건립 및 운영을 필수불가결한 사항으로 인식하고 있다. 그동안 우리나라에서도 국가 대표 과학기술정보의 수집, 관리 및 유통 기관으로서 국내적 위상 제고와 국제적 경쟁력 확보를 위해 국가적 차원의 첨단연구정보 전진기지로서 국가과학도서관의 건립이 부단히 요청되어 왔다. 한 나라의 국가과학도서관은 국가 발전과 번영을 위해 핵심적인 과학기술지식정보 인프라로서, 새로운 지식정보의 생산능력은 이러한 인프라의 용량에 의존하며, 새로운 이론과 기술 및 새로운 비전의 창출은 그 기능에 달려 있는 것이다. 이는 국가적 차원에서 정보주권의 수호와 국가예산의 중복투자 지양이라는 관점에서 다루어지면서, 동시에 충분한 지식정보의 확충을 기반으로 이용자가 만족할 수 있는 인프라로 개발 운영되어져야 하기 때문이다. 향후 우리나라가 지식정보사회에서 선진제국의 지식정보 식민지화나 과학 기술 예속화를 지양하고, 과학기술산업 부문에서 국제경쟁력을 제고하기 위해서라도 이러한 도서관의 건립은 피할 수 없는 과제라고 하겠다. 따라서 본 논문에서는 그동안 국가차원에서 심각한 과학기술정보자원의 부족 및 정보서비스를 활성화하고자 몇 차례 시도된 바 있는 우리나라 국가과학도서관의 건립 및 운영을 연구의 목적으로 설정하고, 이를 달성하기 위해 다음과 같이 세부적으로 고찰하고자 한다. 첫째, 국가과학도서관 건립의 필요성을 살펴보고, 둘째, 그 기능 및 역할을 규명하며, 셋째, 지금까지 논의된 도서관 건립의 과정을 조사 분석하고, 넷째, 최근 국립 과학기술 농학 의학도서관 등 설립 추진 계획이나 세종시의 성격 변화와 같은 주변 환경 등의 변화를 고려하면서 향후 도서관 건립의 문제점 및 발전 방향을 도출하여 제시하고자 한다.

  • Chief Consultant Archives Government Archives & Records Service -table of contents- 1. Introduction 2. Relationship of Historical Studies and Archive 3. Relationship of Archives and Archives 4. Conclusion; Historians, Archives, and Archivists, and Their Roles This essay is mainly written for historians who may have "little or limited experience" in dealing with archives and archivists in their course of historical research. It may sound very ridiculous to say that "historians have little or limited experience" in using archives but it is also true that many Korean historians have depended on various compiled editions of historical materials or personally donated and/or collected materials when they do research, rather than they would visit archives and search for the materials by themselves. This is the main reason for that the public archives in Korea have not served historians well and effectively, and vice versa, that historians have not visited archives sometime with no knowledge of archives, and have not requested opening of archives for their research. It is a simple fact that historian's study depends on the records he/she uses. Without records, there should be no history. Use of archives for historical research is a common thing and a must in modern archives. Records are selected to be preserved in archives for their preservation as well as their future use. Who select the records as archives? Archivists do mostly. Then, what are the criteria for the archivists to chose records as permanent preservable archives? Answers to this fundamental question have been provided by many historians and archivists. The closest answer may be that selecting archivists would be better trained and equipped with historical research and knowledgeable of the major trends in historical research. With his/her own experience of historical research and tracing the trends of historical studies and materials used in the historiography, they could chose better and appropriate records for future use using their prudence and discretion. It also means that historians have had influence on archivists in their selecting archives by providing the theme and context of historical studies of the time. Though not necessarily becoming a historian themselves, selecting or appraising archivists should understand the process of creating the records and should know how they become archives. This is a precondition to become a good archivist. But that's not all. They must know how the archives are used and what archives are used for what purposes. Among many other roles of modern archivists, selecting and describing the archives are the foremost tasks of an archivist. Archivists therefore developed modern methods to select future archives based on functional analysis and records series concept rather than a record file or item as a unit of selection. Historians are users or consumers of the archives held in the archives building or repository. The quality of their study depends on the "quality" of the materials they use. With the help of archivists not to mention of reference service, historians owe much to archivists in having an access to the materials they need, intellectually and physically. Too many closed archives and too long closed archives in the archives repository would benefit neither historians nor archivists. However, archivists can mostly react only to archive requests and demands made by historians for more wide accessibility. Using the FOIA, as in the U.S., or the Information Opening Act, as in case of Korea, historians can promote the use of historical materials as well as promoting accountability and transparence for the benefit to society as whole. In this context, it is vary desirable to establish a close professional relationship between historians and archivists even in the age of information society. At present, historians need more understanding of operation and importance of archives while archives administration need to realize the potential archival demands from research community and civil movement for clean government.
