GMO labeling system in South Korea stipulates three labeling methods: GMO labeling, no labeling and Non-GMO labeling. Products labeled as Non-GMO are not allowed for unintentional commingling of GMO without tolerance. However, consumers vary their acceptance of Non-GMO label on the unintentionally commingled products and willingness to pay according to the mixing rate, rather than devalue the whole products as useless. Additionally, consumers do not believe that the acceptable mixing rate should be discriminated between non-labeled products, which allow up to 3% of unintentional GMO contamination, and Non-GMO labeled products. Information on unintentional GMO mixing mainly refers to the mixing rate, but the Non-GMO content remaining even after commingling is also important information. The decline in value is alleviated when consumers are exposed to positive information, such as Non-GMO content, rather than when exposed to negative information, such as the mixing rate. Loss Aversion Coefficient is relative depending on whether the information representing the loss is positive or negative. Information that a Non-GMO labeled product contains X% GMO is more sensitive than information that (100-X)% Non-GMO remains.

This purpose of this study was to contribute to the establishment of nutriton labeling and consumer education about food label by offereing basic information. Survey was carried out by questionnaire method. Subject groups were middle and high school female teachers and they were asked questions about their utilization and satisfaction of the current food labeling system, their awareness of the nutrition labeling and its necessity, and their acceptance of the future enforcement of nutrition labeling system. Questionnaires were distributed to 500 middle school female teachers in Chungbuk and Kyoggi area. Out of 340 reports(68%) collected, 311 reports(91.5%) were analyzed using SAS computer program. Most of the respondents payed much attention to the labels of the food at the time of purchase, the degree of their satisfaction in the current food labeling system was low. Concerning the awareness on nutrition labeling, Home Economics teachers knew better than non-Home Economics whether there were the regulations of nutrition labeling in Korea or not. Ninety-six percent of respondents answered that nutrition labeling is necessary. Home Economics teachers recognized the necessity of nutrition labeling more strongly than non-Home Economics teachers. Sixty eight percent of the respondents showed positive attitude to the actuation of nutrition labeling.

본 논문에서는 움직임 추정 (motion estimation, ME), 컬러 라벨링(labeling) 그리고 Non-local mean 필터를 이용하여 2D 영상을 3D 업체 영상으로 변환하는 기법을 제안한다. 제안하는 기법에서는 먼저 프레임 간의 움직임을 추정하여 객체의 움직임 벡터를 추출하고 주어진 영상에 대해 컬러 라벨링 작업을 수행하여 영상을 분리한다. 움직임 추정 결과와 컬러 라벨링 결과를 비교 분석하여 영상내의 객체를 추출하고 추출된 객체를 이동하여 우 영상을 생성하게 되는데 이때 우 영상을 생성하는 과정에서 채워지지 않은 가려짐 영역이 발생하며 전체 화소간의 상관도를 고려하는 Non-local mean 필터를 사용하여 보상한다. 이후 원본 영상인 좌 영상과 생성된 우 영상으로 비윌 주사하여 최종 3D 업체 영상을 재현한다. 실험 결과를 통해 제안된 기법으로 생성된 3D 업체 영상에서 객체위주의 안정된 업체 변환이 수행되는 것을 확인할 수 있었다.

본 논문에서는 이진화 영상의 물체 분석에서 자주 사용되는 새로운 Labeling 알고리즘을 제안한다. 제안한 Labeling 알고리즘은 기존의 Labeling 과는 달리 복잡한 Equivalent Labeling Merging/Ordering이 필요하지 않으며 비재귀적인 Flood-filling에 의하여 1 pass에 Labeling이 이루어진다. 또한 Gray-level 이미지에 대해서도 쉽게 확장될 수 있으며, HIPR Image Library를 대상으로 실험한 결과 기존의 방법보다 2배 이상의 빠른 수행 속도를 보였다.

This research aims to develop the multiple channel electrochemical DNA chip using microfabrication technology. At first, we fabricated a high integration type DNA chip array by lithography technology. Several probe DNAs consisting of thiol group at their 5-end were immobilized on the gold electrodes. Then target DNAs were hybridized and reacted. Cyclic voltammetry showed a difference between target DNA and control DNA in the anodic peak current values. Therefore, it is able to detect a plural genes electrochemically after immobilization of a plural probe DNA and hybridization of non-labeling target DNA on the electrodes simultaneously. It suggested that this DNA chip could recognize the sequence specific genes.

본 연구는 위험물 수송의 최적경로를 결정하는 방법론을 제안하였다. 위험물 차량의 최적경로를 결정할 때에는 위험도 최소화를 목적으로 하는 공공의 입장과 통행시간 최소화를 목적으로 하는 민간기업의 입장이 서로 상충한다. 본 연구에서는 이러한 다기준 의사결정(Multi-criteria decision making)문제 중 하나인 위험물 수송용 최적경로를 탐색하는 방법론으로 Efficient Vector Labeling(이하 EVL) 알고리즘을 제시하였다. EVL 알고리즘은 위험도와 통행시간을 동시에 고려하여 복수의 Pareto optimal 경로(또는 비지배경로)를 탐색하게 한다. 본 연구는 또한 탐색된 비지배경로간의 중복도를 제어할 수 있도록 설계하였다. 개발된 Efficient Vector Labeling 알고리즘을 Test bed network에 적용하여 기존의 경로탐색 방법론과 비교하였다. 적용 결과 새로운 알고리즘이 기존의 알고리즘보다 합리적인 대안경로를 탐색할 수 있는 것으로 분석되었다.

An L(p₁, p₂, p₃, . . . , p_m)-labeling of a graph G is an assignment of non-negative integers, called as labels, to the vertices such that the vertices at distance i should have at least pi as their label difference. If p₁ = 4, p₂ = 3, p₃ = 2, p₄ = 1, then it is called a L(4, 3, 2, 1)-labeling which is widely studied in the literature. A L(4, 3, 2, 1)-path coloring of graphs, is a labeling g : V (G) → Z⁺ such that there exists at least one path P between every pair of vertices in which the labeling restricted to this path is a L(4, 3, 2, 1)-labeling. This concept was defined and results for some simple graphs were obtained by the same authors in an earlier article. In this article, we study the concept of L(4, 3, 2, 1)-path coloring for complete bipartite graphs, 2-edge connected split graph, Cartesian product and join of two graphs and prove an existence theorem for the same.

BACKGROUND/OBJECTIVES: The objective of this study was to investigate food allergens and prevalence rates of food allergies, followed by comparison of consumer attitudes and preferences regarding food allergy labeling by diagnosis of food allergies. SUBJECTS/METHODS: A total of 543 individuals living in Seoul and Gyeonggi area participated in the survey from October 15 to 22 in 2013. RESULTS: The results show that the prevalence of doctor-diagnosed food allergies was 17.5%, whereas 6.4% of respondents self-reported food allergies. The most common allergens of doctor-diagnosed and self-reported food allergy respondents were peaches (30.3%) and eggs (33.3%), respectively, followed by peanuts, cow's milk, and crab. Regarding consumer attitudes toward food labeling, checking food allergens as an item was only significantly different between allergic and non-allergic respondents among all five items (P < 0.001). All respondents reported that all six items (bold font, font color, box frame, warning statement, front label, and addition of potential allergens) were necessary for an improved food allergen labeling system. PLSR analysis determined that the doctor-diagnosed group and checking of food allergens were positively correlated, whereas the non-allergy group was more concerned with checking product brands. CONCLUSIONS: An effective food labeling system is very important for health protection of allergic consumers. Additionally, government agencies must develop policies regarding prevalence of food allergies in Korea. Based on this information, the food industry and government agencies should provide clear and accurate food labeling practices for consumers.

The objective of this study was to compare the differences of opinion, purchasing behavior, and recognition of food labeling and nutrition labeling of frozen processed food between employees and non-employees in the frozen food industry. The results of this survey study showed that the group working in the frozen food industry had a positive opinion of frozen processed food compared to the non-employee group who was not working in the food industry. The main reason for the positive opinion of frozen processed food was because it was convenient and easy to prepare while the main concern with consuming frozen processed food was that it was bad for one's health. The most popular menu was western style. Sixty one percent of employees in the frozen food industry preferred the microwave-cooking method, while only 37.9% of non-employees preferred the microwave-cooking method followed by cooking in boiling water (27.6%). There was a significant (p<0.001) difference in the preference of cooking method between these two groups. Most of the respondents considered 'taste' as the most important factor and 32.9% of the respondents selected 'sanitation/health' as the most serious concern for the consumption of frozen processed food. Both groups checked the food & nutrition label to verify the expiration date and the presence of food additives. The non-employee group recognized the need for nutritional information on total calorie, carbohydrate, protein, fat, saturated fat, cholesterol, minerals, vitamins, sodium, and fiber on the nutrition label of frozen processed food.

In this paper we investigate the properties of (a, d)-vertex antimagic total labeling of a digraph D = (V, A). In this labeling, we assign to the vertices and arcs the consecutive integers from 1 to |V|+|A| and calculate the sum of labels at each vertex, i.e., the vertex label added to the labels on its out arcs. These sums form an arithmetical progression with initial term a and common difference d. We show the existence and non-existence of (a, d)-vertex antimagic total labeling for several class of digraphs, and show how to construct labelings for generalized de Bruijn digraphs. We conclude this paper with an open problem suitable for further research.
