  • A unified modal-nodal expansion of tile angular distribution of neutron flux in one spatial dimension is considered, following the proposal of Harms. Several standard nodal and/or modal methods of analysis are shown to be specializations of this technique. The modal-nodal moment from of the mono-energetic transport equation with isotropic sources and scattering is derived and the infinite medium eigenvalue problem solved. The technique is shown to yield results which approximate the exact value of the inverse diffusion length in non-multiplying media more accurately than standard methods of equal or somewhat greater computational complexity.

  • Ethics refers to the principles of right and wrong that can be used by individuals acting as free moral agents to make choices to guide their behavior. Information technology has presented our human mankind not only prosperity but also harms. This is why moral aspects should be addressed in the application of information system. First, a transforming tendency of international economy will be observed. Second, many issues regarding ethics and behavioral courses will be discussed. And a trend of information technology and five moral models will be examined. Third, traditional morals of Koreans and attitudes of Westerners about information technology will be analyzed. Fourth, it will be also discussed how private firms understand ethics and culture in the context of information handling. It is suggested that individuals who use information technology cultivate efficient and effective ethical principles contributing to public good in the society. For this purpose, the government should establish relevant legal devices.

  • In this article, we introduce examples and technologies relating to particulate matter (PM) reduction technology, for the purpose of reducing PM that harms health and affects the entire industry such as dust-sensitive semiconductor industry. First, the definition of PM and how it is generated is explained, including its effects on the human body. In addition, various methods for measuring PM are described, including examples of the restrictions on the operation of polluting vehicles and emission reduction devices. Finally, we describe techniques relating to the reduction and forecasting of PM.

A study for the possibility of international harmonization on alcohol labelling under WTO/TBT (WTO/TBT협정하에서 알코올 라벨링에 대한 국제적 조화 가능성에 관한 연구)

  • This paper determines if mandated alcohol health information labelling could be an obstacle to international trade by discussing international trade rules affecting member nations. WTO members could use alcohol labelling rules to protect human health, reduce the consumption of alcohol and provide product information. When a member uses alcohol labelling as a technical regulation or standard, it should comply with TBT Articles 2.2 and 2.4. If a member uses some specific warning messages for their objectives, it should be considered the contribution of the measure, trade restrictiveness, and alternatives. If WTO members want to employ their own alcohol labelling schemes for addressing carcinogenicity, intoxicating effects, dependence potential, effects on children, adolescents and pregnancy, it could be a technical barrier and also create adverse effects on international trade. Therefore, the harms of alcohol are supported by scientific evidence, and for this reason, the international harmonization for alcohol labelling should be discussed openly to prevent negative effects on trade.

  • Five constituents were isolated from the stem of Acanthopanax senticosus. Their structures were elucidated as (-)-sesamin (1), iso-fraxidin (2), 5-hydroxymethylfurfural (3), syringin (4) and acanthoside D (5) by spectral analysis. Among these compounds, 5-hydroxymethylfurfural (3) was isolated for the first time from this plant.

  • The common recognition which the organic product is compared as safe to baby does not mean there is especially plentiful nutrition in organic product. The part mineral content of agricultural products follows in soil quality, therefore plentiful chemical fertilizer-use to change soil quality results in the possibility of the mineral content change. The vitamin, carbohydrate, protein and fatty acid composition does not change largely from original nutrition facts. Rather than, the most advantage of organic product is relieving baby from agricultural chemical harms. It will be a strong desire for consumers to eat safe, believable and healthy food like organic foods. Furthermore, it will be sincerely good to environment and ecosystem.

  • This study is to improve reasonable consumption as a consumer and interests of the consumers through analyzing the consumer satisfaction degree on product information provided on Internet, and to present basic information to contribute in protecting consumers through preventing harms on them due to insufficient or unnecessary information. The major results of the study are summarized as follows: 1) The degree of understanding characteristics in information focus on household electric appliances provided for the consumers on Internet found to be 'average'. 2) In the degree of significancy for information of the household electric appliances, consumers recognized information regarding services most important. 3) The overall satisfaction degree on information regarding household electric appliances on Internet was evaluated through giving a weight to the degree of significancy for the products and adding the satisfaction degree by information contents, and it was found to be 'average'.
