Purpose: The morbidity of pesticides are largely related with accidental ingestion in human. The four principal ideals of clarity, completeness, conformity and consistency of label are important to make a correct usage and prevent unnecessary health risk. The aim of this study is to evaluate the appropriateness of pesticides labelling practice in Korea. Methods: The photographic label images of pesticide products were gathered through visiting thirteen manufacturers that produce pesticide products in Korea. We scored labelling practice by guidelines of Food and Agriculture Organization of the United Nations in 1995. Results: From August 2005 to November 2005, we gathered 1,296 label images of pesticide and $58.3{\%}$ (755/1,296) of images were scored by check lists for reviewing label content. The average score of four check list categories was $71.9{\pm}2.2$. Each categorical score were $91.7{\pm}0.9$ for the information appearing on the label, $31.3{\pm}0.0$ for safety precaution, $77.7{\pm}2.0$ for instructions for use, $87.0{\pm}8.7$ for general configurations. In safety precaution, the sentence of keeping locked up the product and two mandatory safety pictograms were missed in all label images. In general configurations category, there was score difference in product package types between bottle and bag container ($85.1{\pm}9.0$ vs. $90.3{\pm}7.2$, p < 0.01). Conclusion: Although there was no comparable previous data, the score of safety precaution was lowest than other categories because the two mandatory safety pictograms and locked up warning sentence were missed. In general configurations, the colour contrast was more inappropriate in the labels on bottle than bag container.

락토퍼옥시데이즈(lactoperoxidase, LPO)를 사용하여 인슈린을 $^{125}$/I로 표지반응 시켰다. 반응생성물은 전분젤 전기영동(SGE) 과 세파덱스 젤여과(SF) 둥 두단계를 거쳐 정제하였다. 표지수율 과표지생성물의 항체에 대한 결합능으로 보아 종래의 클로라민-T법 (표지수율 약 35%)보다 효소법 (표지수율 약 50%)이 우수하였다. 인슈린의 첨가없이 LPO법으로 표지반응을 진행시킨 다음 SGE, 종이 크로마토그래피, 방사선사진술 등을 적용하여 LPO법에서의 부산물을 확인할 수 있었다. SGE와 SF에서의 분리 분별 부분에 관해서도 분석, 토의하였다.

The purpose of this study was to investigate school dietitians' use of processed and packaged foods in Incheon. This study was carried out through a questionnaire and the subjects were 203 school dietitians in Incheon. The results are summarized as follows. Dairy product was the processed and packaged food used most frequently by the subjects for school lunch. Most subjects used processed and packaged foods for school lunch once or twice per week. The first criteria for their choosing processed and packaged foods was manufacturing company. Also major reason for their using processed and packaged foods for school lunch was saving cooking time, easy purchase, hygienical packing and less garbage. The most common information source on processed and packaged foods for school lunch was promotion of food company. The subjects checked labelling of processed and packaged foods in order of open-date, manufacturer, origin of product, nutrition facts, ingredients and food additives. Some results were significantly different among the subjects by employment school, type of meal management and cost per meal. For children and adolescents' nutrition and well-being through school lunch, it is necessary to prepare a database of the processed and packaged foods and education program concerning nutrition labelling and food safety.

In Korean Electric Motor Unit(EMU) industry, the government should lead and drive the development of the product-oriented fundamental technologies(for example, Life Cycle Assessment, Environmental Labelling, Ecodesign, Eco-efficiency etc.) for the EMU. International Railway Union(UIC) establish UIC code 345: Environmental specification and it is based on using the product-oriented fundamental technologies. And also many foreign railway related companies already shown their environmental performance using the product-oriented fundamental technologies So, in Korean situation, it is important that let the EMU industrial player understand the importance of the product-oriented fundamental technology for the EMU and clarify who drive the development of the product-oriented fundamental technology for the EMU and what the type of driving forces.

Memantine HCl을 자외부 유도화제인 MPCN과 반응시켜 흡광광도법으로 정량하였다. 유도화반응은 pH 5, $50^{\circ}C$에서 MPCN을 1:20배 몰비로 사용하여 30분간 반응시켰으며 dichloromethane으로 추출한 후 324.5nm에서 흡광도를 측정하였다. 그 결과 memantine HCl의 최종 농도로써 $5.0{\times}10^{-6}{\sim}6.5{\times}10^{-5}M$ 사이에서 직선성을 나타냈으며 detection limit는 $0.43{\mu}g/ml$이었다. 본 분석법을 제제에 적용하였을 때 주사제는 $100.08{\pm}0.72%$였고 정제는 $99.75{\pm}0.77%$로, 부형제에 의한 영향 없이 간편하고 신속하게 재현성 있는 결과를 나타내므로 의약품의 품질관리에 효과적으로 응용될 수 있으리라 사료된다.

최근 공산품에 나노기술의 활용이 점점 확대되고 다양한 나노제품이 출시되면서 나노물질의 인체 및 환경에 대한 유해성 문제가 주요한 사안으로 대두되고 있다. 이러한 위험성을 인식하여 EU 및 미국 등에서는 나노물질에 대한 규제를 강화하는 추세이다. 그러나 현재 국내에는 나노관련 법규가 미흡한 형편이다. 무엇보다도 소비자에게 밀접한 공산품의 나노물질 규제정책은 소비자의 안전을 위해 시급히 요구되고 있다. 이에 따라 본 연구에서는 규제정책 도입을 위한 기반연구로서 공산품에 함유된 나노물질에 대한 규제정책 도입을 위한 분석을 실시한다. 본 연구에서는 AHP(Analytic Hierarchy Process) 기법을 적용하여 규제정책을 평가하고 가장 적합도가 높은 최적 규제정책을 선택한다. 규제정책은 자율규제, 제품라벨링, 정부등록제를 대상으로 하며 정책평가기준은 시행성(효과성), 경제성, 수용성, 보호성으로 설정한다. 평가 결과 최대 적합도를 가지는 제품라벨링 정책을 최적 규제정책으로 선택한다.

In this study, we compared nutrient content emphasized on labelling of processed milks with that of whole milks and evaluated how well they conform to labelling standard. A total of 98 samples (33 whole milks, 28 calcium fortified milks, 30 low-fat milks and 7 lactose hydrolyzed milks) were collected in hypermarkets in Seoul from August 28 to August 30 in 2012. Calcium, fat and lactose contents were tested in the samples. Calcium contents ranged 102.2~113.0 mg/100 mL in whole milks and 120.1~337.8 mg/100 mL in calcium fortified milks. The level of calcium contents in fortified milks ranged very broad. Accordingly, the standard of calcium contents on fortified milks will be required. Fat contents ranged 3.1~3.9 g/100 mL in whole milks and 0.1~1.9 g/100 mL in low-fat milks. The average of fats content in low-fat milks was nearly one third than whole milks. Lactose contents was ranged 4.6~5.1 g/100 mL in whole milks and not detected in lactose hydrolyzed milks. All of processed milks were suitable to processing standard and labelling standard. But nutrition claims often used on processed milk such as "High" or "Low" were not adequate to indicate the exact nutrient content, which is a cause of the confusion for milk product labelling to consumers. We need a lot of research about nutrient labelling that can deliver appropriate and understandable information to customers.

Reverse edge magic(REM) labeling of the graph G = (V, E) is a bijection of vertices and edges to a set of numbers from the set, defined by λ : V ∪ E → {1, 2, 3, …, |V| + |E|} with the property that for every xy ∈ E, constant k is the weight of equals to a xy, that is λ(xy) - [λ(x) + λ(x)] = k for some integer k. We given the construction of REM labeling for the Cartesian Product, Unions of Braids and Unions of Triangular Belts. The Kotzig array used in this paper is the 3 × (2r + 1) kotzig array. we test the konow results about REM labelling that are related to the new results we found.
