전 세계 수목원 및 표본관이 보유하고 있는 식물 유전자원 현황 및 정보 공유체계를 효과적으로 활용한다면, 현재 물리적으로 접근이 어려운 북한지역의 생물다양성 보전체계를 구축할 수 있을 것으로 생각된다. 본 연구는 북한에 자생하지만, 국내(남한)에는 자생하지 않는 식물들에 대한 학명을 검토하고 국내·외 수목원의 유전자원 보유 현황을 파악하기 위해 수행되었다. 북한식물 목록 선정을 위해 한반도 관속식물과 관련한 문헌이나 온라인 식물 종 데이터베이스를 참고하여 재배 및 외래식물 여부, 이명, 분포 범위 등을 검토하였으며, Botanic Gardens Conservation International Plant Database와 각 수목원의 Index Seminum을 활용하여 북한식물에 대한 전 세계 수목원의 유전자원 보유 현황을 파악하였다. 64과, 236속, 449종, 13아종, 21변종, 1품종, 2교잡종 등 486분류군에 대한 북한식물 목록을 선정하였으며 희귀식물, 특산식물, 북방계식물 등의 여부를 확인하였다. 전 세계 5개 대륙, 46개 국가, 333곳의 수목원 및 식물 연구기관에서 53과 190속 384분류군의 북한식물 유전자원을 보유 중인 것으로 확인하였다. 북한 지역과의 지리적 근접성, 과거 식물학자의 이동 등의 요인으로 한국, 일본, 러시아 등 동북아시아 국가가 보유하고 있는 북한식물 유전자원 종 다양성이 상대적으로 높은 것으로 확인된다. 본 연구는 북한 자생식물 종 목록 구축 및 응용을 도모하여 한반도 생물 다양성 보전을 위한 과학적 기반 마련과 글로벌 거버넌스 구축에 이바지할 것으로 생각된다.

Web offset newspaper prints is the most widely used printing process in domestic printing industry, but there are no industry-wide specifications for press control to assure consistent quality across newspaper printing plants. As newspaper printing becomes more of a commodity and less of an art, it is necessary to develop the print quality specification standard suitable for Korea web offset newspaper printing field. There are a few commonly employed printing standards such as, SNAP(Specification for Non-Heatset Publication) of the US, IFRA(INCA-FIEJ Research Association), J-color (Japan printing machinery association). And there exists KS for domestic standards, however, since it has been directly imported from ISO standards, there are discrepancies in printing materials and media. This paper aims to examine the color reproduction quality of domestic web offset newspaper prints by comparing with foreign standards. Printing experiments on this study have been performed at one of the domestic newspaper printing companies. The color reproduction properties of the web offset newspaper prints are measured by means of densitometry and colorimetry. These measures are evaluated comapratively with the international standards by means of analyzing, the major factors that determine the color reproduction quality of web offset newspapar prints.

In a fire hazard analysis (FHA) for nuclear power plant, various electrical circuit analyses are performed in the parts of fire loading analysis, fire modeling analysis, separation criteria analysis, associated circuit analysis, and multiple spurious operation analysis. Thus, electrical circuit analyses are very important areas so that reliability of the analysis results should be assured. This study is to establish essential electrical elements for each analysis for verification of the reliability of the electrical circuit analyses in the fire hazard analysis for nuclear power plants. Applying the results derived by the study to domestic nuclear power plants, it is expected to determine the adequacy of the fire hazard analysis report and contribute to the reliability of the fire hazard analysis of those plants.

Based on the results of Probabilistic Safety Assessment(PSA) for a Nuclear Power Plant (NPP), Common Cause Failure(CCF) events have been recognized as one of the main contributors to the risk. Also, the CCF data and estimation method used in domestic PSA models have been pointed out as an issue with respect to the quality. The existing method of MGL and non-staggered testing even widely used were considered conservative in estimating the safety and had a limited capability in uncertainty analyses. Therefore, this paper presents the CCF estimation using a new generic data source and Alpha factor method. The analyses showed that Alpha factor and staggered method are effective in estimating the CCF contribution and risk insights of reference plant. This method will be a common bases for the optimization of new design for the construction plants as well as for the updating of safety assessment on the operating nuclear power plants.

In the domestic nuclear power industry, concern about safety of nuclear power plants is continuously increased with the Fukushima nuclear power plant accident. In order to enhance the safety of nuclear power plants, it is important to ensure that the power plants are operating with proper margin within the original design bases. Margin management is the process of ensuring that the NPP designer and operator are aware of the physical and operating limits, and potential and probability of failure, for each component in the plant. All components are subject to margin considerations, but the most important components by scope and attention are those related to safety-related systems and NPP safe shutdown.

The most components and piping of the secondary side of domestic nuclear power plants were manufactured carbon-steel and low-alloy steel. Flow accelerated corrosion leads to wall thinning (metal loss) of carbon steel components and piping exposed to the flowing water or wet steam of high temperature, pressure, and velocity. The feedwater heaters of many nuclear power plants have recently experienced sever wall thinning damage, which increases as operating time progress. Several nuclear power plants in Korea have also experienced wall thinning damage in the shell wall around the impingement baffle. This paper describes the comparisons between the numerical analysis results using the FLUENT code and the experimental results based on down-scaled experimental facility. The experiments were performed based on several types of impingement baffle plates which are installed in low pressure feedwater heater.

Recently, serious problems occurred such as insecticide eggs, sanitary pads with carcinogens, radon(Rn) emitting beds in domestic. It had not been establishing the inspection system to evaluate safety and human harmfulness before occurring real accidents. This research was conducted to test preliminary experimental inspection for consideration of safety insensibility. The influence of corrosion of metals and plants was studied through aerosol type spraying of agricultural pesticide products coming into the market. These products contain primary three insecticide ingredients(Flufenoxuron, Etoxazole, Fipronil) in recent accidents. Visual examination, SEM-EDS and optical microscope were used for the analysis for corrosion effect. Results show that a lot of ingredients contain in the crop protection products, and various type of corrosion exist in the surface of metals and plants. Therefore, it is necessary to provide health warning and accurate range of use for crop protection products containing insecticide ingredients.
