  • 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.

  • This paper deals with inspect algorithm using visual system. One of the major problems that arise during polymer production is the estimation of the noise of the color product.(bad pallets) An erroneous output can cause a lot of losses (production and financial losses). Therefore new methods for real-time inspection of the noise are demanded. For this reason, we have presented a development of vision system algorithm for the defect inspection of PE color pallets. First of all, in order to detect the edge of object, the differential filter is used. And we apply to the labelling algorithm for feature extraction. This algorithm is designed for the defect inspection of pallets. The labelling algorithm permits to separate all of the connected components appearing on the pallets. Labelling the connected regions of a image is a fundamental computation in image analysis and machine vision, with a large number of application. Also, we suggested vision processing program in window environment. Simulations and experimental results demonstrate the performance of the proposal algorithm.

  • Insulin was labelled with $^{125}$ I using lactoperoxidase as an oxidizing agent. The reaction product was purified via two stages: a starch gel electrophoresis(SGE) and a Sephadex gel filtration (SF). Upon comparison of the labelling yields and the bindabilities of the labelled insulin to its antibody, it has been found that the enzyme method shows higher yields (50%) and the better bindability to its antibody than the conventional chloramine-T method (35%). By checking the insulin blank labelling mixture with a SGE, a paper chromatography, and a radioautography technique, a by-product in the lactoperoxidase method has been identified. The separated fractions in SGE and SF were also analyzed and discussed.

  • 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.

  • Spectrophotometric assay for memantine HCl was developed by using sodium 1-(4-methoxypheyl) cinnamonitrile-2-sulfonate (MPCN) as an UV labelling reagent. The optimum derivatizing condition was obtained by incubation for 30 min at pH 5.0 in the presence of 20-fold molar excess of the labelling reagent. The absorbance of reaction product was measured at 324.5 nm and detection limit was $0.43{\mu}g/ml$. A linear range was $5.0{\times}10^{-6}{\sim}6.5{\times}10^{-5}M$ of memantine HCl. The linear regression analysis of absorbance at various drug concentration was r=0.9998 (n=6). When applied to memantine HCl ampule and tablet, it gave the mean contents of $100.08{\pm}0.72%$ and $99.75{\pm}0.77%$, respectively.

  • Recently, the use of nanotechnology in products is constantly expanding, and the problems on human health hazard has emerged as a major issue. A nanomaterials regulatory policy on the products is urgently required. This study analyzed the introduction of regulatory policies of nanomaterials contained in industrial products. In this study, the AHP (Analytic Hierarchy Process) method was applied and three regulatory policies were evaluated to analyze the validity of the introduction of a nanomaterials regulatory policy. To select the optimal regulatory policy, the policy evaluation criteria were set as enforcement (effectiveness), economics, acceptability, and protection. For the regulatory policies, self-regulation, product labelling, and enforced registration were introduced and evaluated as the regulatory policies, and product labelling was selected as the optimal regulatory policy.

  • 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.
