결정입내에 분산입자를 갖는 Al-Mg계 합금의 고온 연성저하 현상

金炳日 順天大學校 1997 論文集 Vol.16 No.1

The dependency of the ductility of Al-Mg-Be alloy containing transgranular particles on temperature and strain rate was examined by using tensile test. The ductility minimum was found to be at 573K for ?? in notched specimen and reduction of area increased with increasing temperature up to 523K in no notched specimen. The rate of ductility loss increased at lower strain rate. However, the maximum ductility was drop occurred at the same temperature, 573K for various strain rate. The reduction of area was not determined uniqely by Zenner-Hollomon parameter, ??. The fracture of cleaver type showing the ductility loss at higher temperature was associated with cavity growth as well as interlinkage of cavities, while a number of dimples were observed on the fracture surface at lower temperature.

Sec. 17 Copyright Act provides that an author shall have the right to perform his work publicly. However, See. 1 Copyright Act states that the goal of the Act is to contribute to the development of culture by providing protection to copyright and by promoting fair exploitation of works of authorship. The interests of the public are secured through various limitations and exceptions set forth in Subchapter 6, Limitation of Copyright (Sees. 22 through 35). Sec. 26 provides that works may be publicly performed or broadcast for a non-profit purpose and without charging any fees to audience or without receiving any ? fees from elsewhere. The cases where a remuneration is paid to the person who makes such public presentation is an exception, Sec. 26(1). Commercial phonorecords may be heard or shown for a non-profit purpose and without charging the audience any fees, See. 26(2). In this article, I intend to review whether the Copyright Act balances the conflicting interests of an author and the public in the field of music performance.

Radiation Exposure during ERCP after F-18 FDG PET Examination and Health Effect

김병일 대한췌담도학회 2013 대한췌담도학회지 Vol.18 No.1 Suppl

The more nuclear medical examinations are clinically used, the more concern about radiation exposure to medical staff is increasing. In this article, radiation exposure to medical staff during ERCP after F-18 FDG PET examination and health effects will be discussed. Using the easy estimation the radiation exposure to medical staff during ERCP after F-18 FDG PET when contact distances of 50, 60, 70, 100 cm, and the contact time with the patient at 10-minute intervals could be made as a table form. According to this table, if ERCP performed for 20 min at a distance of 70 cm 2 hours after injection of 10 mCi F-18 FDG, radiation exposure was estimated 7.88 μSv. Low dose radiation is set less than 100 mSv because there was no direct epidemiological evidence of cancer increase in the Japanese atomic bomb survivors study in this range. So, interpretation of human health effects at low dose radiation range based on radiation biologic experiments. Based on these experimental results, ICRP supports LNT (Linear No Threshold) hypothesis which means cancer incidence or genetic effects are proportional to radiation dose. However, there are opposite hypothesis to LNT also. Therefore, the results about radiation biologic experiments are incomplete and controversial. We are living in the environment, where 0.7 mSv annual natural radiation dose can vary depending on the region. This natural radiation dose is socially well accepted because we cannot control. In hospital radiation worker, radiation exposure of reasonable level should be able to be accepted because one of the principles of radiation protection is as low as reasonably achievable. If there are conflicts about radiation exposure to medical staff in hospital, there is a need to consider whether these conflicts associate with personal radiation acceptance.

Adornments Used by People of Central Asia and Its Managerial Implications

김병일,권오병 한국로고스경영학회 2019 로고스경영연구 Vol.17 No.3

In this study, adornment items of cults which existed before the era of Islam are described in detail. We consider adornments with relation to their value as a source of investigation of religion beliefs. Adornments of different forms and shapes concerned with various cults and popular beliefs are discussed in detail. In particular, the crosses of the Nestorians are found throughout Central Asia, including stones, cushions, breastplates, and accessories. The data presented confirms that the ancient religious customs evident at the present time existed in various forms for a thousand years, and that the evolution of these customs is reflected in these objects in their various forms. The fact that there were interesting religious adornments before the Islamization of Uzbekistan is significant from a corporate management standpoint, as it involves the handicraft, fashion, and tourism industries in this country. In addition, the niche market for these items is recognized. We provide a textual analysis of the literature on adornments over the centuries.

유전자원 관련 전통지식의 보호와 지적재산

김병일,김경준,채지영 한국지식재산학회 2006 産業財産權 Vol.- No.21

The traditional knowledge("TK") and practices of indigenous and local communities that are developed and passed on through traditional culture are closely linked to the conservation and sustainable use of biodiversity. But there is no protection for the traditional knowledge obtained by indigenous or local communities, usually from developing countries, through collective processes that may have taken even centuries. Advocates for conventional intellectual property systems argue that intellectual property rights create effective incentives for innovative use of biodiversity, which in turn creates profits on which innovators can draw in negotiating benefit-sharing arrangements with the holders of traditional knowledge and biodiversity. Nowadays, the implications of conventional intellectual property systems for traditional knowledge and biodiversity have been the subject of a polarized international debate. Traditional knowledge includes a vast and complex amount of manifestations. This article, nonetheless, will deal exclusively with TK related to genetic resources. Its protection from the perspective of the framework of multilateral treaties, the possible protection through existing intellectual property rights and the search for an alternative solution. This article has sought to suggest how Intellectual Property system could be a tool to protect traditional knowledge.

정보의 공유와 이용에 관한 법적 쟁점

Popular Internet software based on a peer-to-peer architecture has been used to share copyrighted movies, music, software, and other materials. Concerned about the consequences of illegal copying and distribution on a massive scale, most lawyer are interested in strengthen copyright protection levels. Unfortunately, the legal approaches for securing digital copyrighted works are formidable and may be not suitable solution for internet distribution of copyrighted works. We need be mindful that the copyright law has the goal of promoting the widespread dissemination of original expression as well as its creation. This article has focused on four important legal issues surrounding information sharing and its use In particular, those legal issues include tragedy of the commons, open source software, creative commons license, property rule & liability rule, and access right. This study aims to offer a better understanding of the legal issues related to information sharing and its use in digital era. 최근 인터넷 기술 등의 발달로 P2P(Peer to Peer) 사이트, 웹하드 사이트를 통한 저작권 침해가 광범위하게 확산되고 있다. P2P에 의한 파일교환은 정보처리나 전달의 최적화를 도모할 수 있는 반면, 익명성이 있는 콘텐츠의 거래를 위하여 저작권자의 허락을 얻지 않고 파일교환을 행하여지고 저작권 침해의 위험성이 높다는 것이 특징이다. 최근 인터넷상에서 효과적으로 저작권을 보호하기 위한 저작권법 개정이 지속적으로 이루어져 왔다. 그러나 새로운 디지털 환경에서는 저작권은 어떻게 정립하여야 할 것인지가 문제된다. 본 글에서는 디지털 환경에서 생산되는 새로운 정보와 콘텐츠들의 생산·유통·분배를 어떻게 다루어야 할지에 대한 근본적인 검토와 관련하여 정보공유(情報共有)와 자유이용 운동, 저작권제도의 패러다임 변화, 저작물의 공정이용, 접근권과 정보이용의 조화 등에 초점을 두고 검토한다.

정부의 지속적인 녹색성장 정책의 영향으로 기존의 국내 고분자 가공 및 친환경 건축자재 개발 등의 활성화로 국내 기술수준은 해외에 뒤처지지 않은 것으로 분석되고 있으나, 원천기술에 대한 해외 의존도가 상대적으로 높다. 해외기술과 기술격차를 빠른 시일 내에 줄이면서 국내에서의 우수한 생산 및 가공 기술을 이용하여 다양한 시장 창출이 필요한 시점에 있다. 본 연구에서는 생분해성 수지(PLA, PCL, PBS 등) filler를 투입하여 생분해 시간을 조절하는 기술 및 물성강화연구에 초점을 맞춘 생분해 기술을 통해 생산된 복합형 식생매트의 현장적용에서 분해단계까지 전과정평가방법을 통한 친환경성평가에 관한 연구를 수행하였다.
