미국의 비파괴검사기술자 자격인정제도의 운영동향

하기수 한국비파괴검사학회 2003 학술대회 논문집 Vol.- No.1

각국의 비파괴검사기술자에 대한 자격인정제도는 그 근본취지나 인정절차 등에 있어서 서로 유사한 부분이 많이 있음에도 불구하고 체계 및 세부내용이 상이한 점과 자국 보호정책 혹은 상호인정의 결핍에 의해 기술자 개인이나 소속 기관은 동일 분야의 자격을 중복하여 취득하는 경우가 많았다. 특히 우리나라의 경우에는 국가기술자격법에 따른 비파괴검사부문 국가기술자격자가 많이 배출되어 있는데도 외국 자격, 특히 미국 ASNT의 NDT Level에의 의존도가 대단히 큰 현실임을 부인할 수 없는 실정이다. 그 중에서도 핵심사항인 ASNT의 NDT LevelⅢ프로그램은 세계 50개국 이상에서 5000명 이상의 기술자를 배출하여 다른 국가에서 비파괴검사 자격을 취득하게 되는 최대 인정기관으로 볼 수 있다. 비파괴검사기술자 자격의 국제규격 부합화와 향후 국내 비파괴검사 자격제도 운용에 대한 개선대책이 필요한 시점에서, 여기서는 ASNT의 자격인정제도인 SNT-TC-1A, CP-189 및 ACCP의 내용을 비교 설명하고 그 현황을 분석하였다.

To investigate the nephrotoxic potential of melamine (MEL) and cyanuric acid (CA) in male Sprague-Dawley rats,7-d repeated-dose studies were performed. The experimental groups of MEL100 and CA100 were orally administered with MEL and CA at 100 mg/kg/d for 7 d, respectively. In groups dosed with MEL-CA mixtures, melamine and cyanuric acid (1:1) were simultaneously administered at 4, 20, or 100 mg/kg/d for 7 d (i.e., MEL-CA4, MEL-CA20, or MEL-CA100, respectively). Body weights were not markedly affected in MEL100, CA100, and MEL-CA4 groups, but significantly reduced in MEL-CA 20 and 100 rats. Most parameters deter-mined in sera and tissues were not markedly altered in MEL100, CA100, and MEL-CA4-treated rodents, However, BUN, creatinine, total protein, and kidney weights were significantly increased in MEL-CA20-and MEL-CA100-treated animals. Renal histopathologic findings also revealed signs of toxicity, including tubular dilatation, crystal deposition, granulomatous tubu-lo-interstitial inflammation, and tubular necrosis with regeneration. Data suggested that the combination of MEL and CA might be responsible for observed nephrotoxicity that was not seen following individual exposure to either MEL or CA alone. Subsequently, the concentra-tions of MEL and CA were determined in serum, urine, and kidney tissues by using liquid chromatography-mass spectrometry. Toxicokinetic studies indicated that MEL or CA alone might be eliminated almost completely within 24 h after dosing showing no accumulation in kidney. However, the combined MEL-CA dose produced marked accumulation of chemicals in blood and kidneys. These results suggested that combined MEL and CA might produce renal toxicity due to significant chemical accumulation in kidney accompanied by low excretion.

경쟁정책으로서 지상파방송 재송신 정책 : 방송콘텐츠 접근 규제틀을 중심으로

노기영(Ghee Young Noh),김대규(Daegyu Kim) 문화방송 2011 방송과 커뮤니케이션 Vol.12 No.2

본 연구는 방송의 산업화와 새로운 시장 경쟁상황에서 발생하고 있는 지상파 재송신 문제를 분석하고 새로운 방송시장 환경에서의 지상파 재송신 제도의 목표와 개선방향에 대해 제시해보고자 하였다. 현재 우리나라 지상파방송 재송신 정책은 방송콘텐츠에 대한 시장지배력의 정도와 경쟁상황을 토대로 하는 방송콘텐츠 접근정책이라는 포괄적인 규제틀을 적용할 필요가 있다. 방송콘텐츠 접근정책은 보편적 접근권의 관점에서 전통적인 공익규제의 범위를 넘어서 시장의 경쟁을 통해 산업을 활성화시킬 수 있는 경쟁규제의 원리를 포괄하는 규제방식이라 할 수 있다. 이와 같은 방송콘텐츠 접근정책의 규제틀은 방송 산업의 구조와 생산방식에 따라 네트워크사업자, 플랫폼사업자, 콘텐츠사업자들에게 각각 보편적이고 필수적인 콘텐츠에 대한 접근을 통한 공정한 경쟁을 할 수 있도록 규제를 부과하는 정책이다. 이를 위해 공영방송에 대한 의무송신, 공공채널에 대한 의무운용과 함께 주요 지상파채널과 유료방송채널에 대한 의무제공의 세 가지 콘텐츠 접근정책이 방송시장의 경쟁상황에 따라 균형적으로 적용되어야 한다는 점을 제시하고 있다. This study examined several issues of terrestrial broadcasting retransmission (TBR) in the changing status of competition in broadcasting market. With the review of TBR system in Korea, this policy paper tried to suggest a goal and direction for enhancement of TBR system in the new environment of broadcasting market. Regulation of TBR should be established in the comprehensive regulatory framework of content access policy for broadcasting industry considering market power and the status of competition in broadcasting content. Broadcasting program access policy contains the principle of competition regulation which can stimulate the industry with the traditional regulation for public interest based on universal access right. Such regulatory framework of broadcasting program access policy imposes symmetrical regulation to network, platform, and contents providers so that they can compete fairly through access to universal and essential contents. Accordingly, this paper suggested that three content access policy-must-carry of public broadcasting, must-distribute of public channel, and must-offer of major terrestrial channel and popular cable TV channel-should be applied with symmetry according to the status of competition of broadcasting market.

This study aimed to identify operational realities and overall perceptions of conducting the transition education schools for the visually impaired. In order to achieve this purpose, a survey was conducted with 152 teachers at the high school level in 12 schools for the visually impaired. The results were as follows. First, many of the respondents expected that the transition education will improve the quality of life, showing generally normal level of understanding on the concept of the transition education and the transition education plan. However, they were skeptical of its implementation in accordance with the intent of the transition education program. Second, School facilities were used for vocational education. It was positive to secure facilities, tools and materials for vocational education; and vocational education teachers had professional qualifications. Pre-college courses and college preparatory programs were also insufficiently operated. Third, Several problems were raised in planning and operating the transition education: lack of administrative/ financial support from the government, lack of transition education specialists, and insufficient cooperation between community agencies in supporting the transition education. Cooperation and support are still passive at this point in time with regard to cooperation with families including parents, support from the office of education. Urgent problem to be solved was to develop programs and facilities for the transition education; next was to expand opportunities of the transition education training for special education teachers; and to cultivate and secure the transition education specialities.
