A new algorithm for filling the interior of contours and labelling each filled region concurrently is presented. Filling is simply accomplished by inversion method. The labelling information in every scan lines is extracted directly from current direction of chain code so that the proposed algorithm needs less comparision and is more efficient. The contours are followed by two different directions, clockwise for the outer contour and counterclockwise for the inner contour to get filling and labelling information. This algorithm can be applied in case that contours are nested or regions are continous. Simulataneously the proposed algorithm can find the structure tree of object without additional post processing.

The consumers' purchase experiences of some imported agricultural products (rice, sesame, garlic, onion, jujube, red pepper, oak mushroom, apple, dried persimmon) and their consciousness for the labelling of the country of origin for agricultural products in Youngnam region were examined in this study. The sample consisted of 438 women who lived in Taegu, Pusan and other cities of Kyungpook and Kyungnam, and the self-administered questionnaire for the survey was used. The main reasons to purchase the imported agricultural products were the wide distribution and low price of them. Most of the consumers were concerned about safety of the imported agricultural products but only a few people experienced unsatisfaction of the products. The price, quality, package, container, label, and safety of the examined products were evaluated worse than those of the domestic products. Generally, although they suffered unsatisfaction, the consumers did not complain because they wanted to avoid troublesome work, which means the consumers did not assert their rights. Some people did not know the labelling system for the country of origin and the place to charge the market violating it. Therefore, it will be necessary for the consumers to receive education about the labelling system for the country of origin and the compensation criteria for consumers' grievances and damages. The current labelling method for the country of origin generally met the consumers' preference but the consumers wanted to improve the position and color of the label. Most consumers could not differentiate the imported products from the domestic products. The results obtained from the survey suggest consumer education for the labelling system for the country of origin and the compensation criteria should be activated through various ways such as mass media and consumer organizations.

Antibodies were raised against fusion proteins of the N-terminus and a region containing the GDNQ (Gly-Asp-Asn-Gln) polymerase motif of the L (polymerase) protein of sonchus yellow net virus (SYNV). Immunoblot analyses using these antibodies revealed the presence of the L protein in purified SYNV preparations and in nuclear extracts from infected tobacco. The serological analyses and detection in a polyacrylamide gels suggested that the L protein is present in at least a 20 fold lower abundance than the G, N, M1 and M2 proteins, and has size corresponding to a molecular weight of over 200 kDa as predicted from nucleotide sequence data. Electron microscopy with gold-labelled antibodies was used to localize the N, M2, and G proteins of SYNV in thin sections of infected tissue. When sections of SYNV-infected tissue were treated with antisera against total SYNV proteins and N protein, gold label could be detected in both the viroplasms and in virus particles. With the anti-M2 protein antiserum, the gold label was strongly localized in the viroplasms but only limited labelling of the virus particle sonly. Limited labelling of the L protein was observed in the viroplasms and the virus particles, presumably because of the low abundance of L protein in the tissues.

Food allergy refers to an immunologically mediated adverse reaction to food, mainly to proteinaceous constituents. Health implications vary between those individuals who experience mild physical discomforts to those with fast-acting, life-threatening anaphylactic reactions. The prevalence of food allergy is higher in children than in adults, estimated around 4-8% and 1-2% respectively in developed countries. Food allergy has no effective cure at the present time and total avoidance of causative foods is the most reliable prophylactic method currently recommended by the medical community. To help food allergic patients to make informed choices of their foods, mandatory labeling of selected food allergens has been introduced in several countries. All food allergen labelling provisions specify a set of allergens common to the regulated countries. Policy divergence, however, exists between countries by inclusion of additional allergens unique to specific countries and enforcement of specific labelling requirements. Such variations in food allergen labelling regulations make it difficult to manage allergen labeling in imported pre-packaged food products. This paper addresses two current issues in food allergen regulation: 1) an urgent need to determine true prevalence of food allergy in the Asia-Pacific region. This will enable refinement to the food allergen regulation to be more country-specific rather than simply adopting CODEX recommendations. 2) There is an urgent need for harmonization of food allergen regulation in order to prevent food allergen regulation becoming a trade barrier.

경계선 추적을 통해서 결정된 영역의 내부를 래스터 스캔하면서 내부를 일정한 값으로 채워 넣는데 이를 '색칠하기(blob coloring)'라고 하며 보통은 '연결 성분 라벨링(Connected Region labeling)'라 부른다. 이 과정은 각 독립적인 영역들을 고유의 라벨 값으로 구분하여 표시하게 된다. 본 논문에서는 래스터 스캔 결과로 산출된 동치테이블을 동일한 라벨끼리 그룹화 하는데 수많은 그룹이 서로 얽혀서 복잡하므로 신속하고 간단하게 처리할 수 있는 개선된 알고리즘을 제안하고자 한다. 동치테이블 내에서 동일한 그룹으로 묶기 위한 이동 절차를 8단계 알고리즘으로 제시하고 이에 따른 수행 결과를 보여준다.

The purpose of this study was to analyze University student's dietary behavior for processed foods and recognition on food nutrition labelling according to the degree of health concern. For this study, 302 University students in Gyeonggi region was surveyed by questionnaire from May in 2016 and it included the questions about general matters, dietary behavior on processed foods, and the food nutrition label system. It was analysed by SPSS win 23.0 program. And the results are as follows. According to the result of the factor analysis, the preference of processed foods were showed 3.21~3.97. There were significant differences in milk and milk products preference according to health concern (p<0.05). Also frequency of processed foods was shown significant differences in milk and milk products, noodles, beverage, and fast food (p<0.05), whereas no significant differences were found in meat products, snack, bread and frozen food (p>0.05). Also, the processed food purchase consideration according to health concern was shown significant differences in nutrition, origin, manufacturing company (p<0.05), whereas no significant differences were found in taste, price, exterior, brand, and shelf life (p>0.05). Thus, it is necessary to do continuing public relations and to provide more opportunities for nutrition education so that the University students may obtain right dietary behavior on processed foods and the system of food nutrition indication be established properly.

This study aimed to segment Chinese fisheries consumer market by means of cluster analysis based on Shanghai region consumers. The survey is conducted to 350 shanghai people on March 17-21 in 2014 and investigate demographic characteristics and consumer's behaviors unique to each segmented market by preference, labelling, quality, price, safety. The result of cluster analysis identified four market segments such as Catering type market, Worth pursuing type market, Substance pursuing type market, Trend pursuing type market. Catering type market is a passive fisheries consumption market and is not high attractive for Korea fisheries export market. Value pursuing type market consider importance to labelling, origin, brand and require high-quality and differentiation strategies. This market's main target species are high price fisheries such as tuna, salmon, crocker. Substance pursuing type market consider fisheries's safety and quality and purchases more popular fisheries such as crocker, hairtail, promfret, mackerel, squid. Trend pursuing type market's consumers prefer to purchase brands and trendy seafood rather than taste.

The purpose of this study was to compare the bone formation, maturation around HA-and titaniumcoated dental implants in dog. 5 hydroxyapatite coated IMZ implants and 5 titanium coated IMZ implants were placed into the previously extracted site in the mandible of 5 adults dogs. All dogs were injected intravenously Tetracycline, Alizalin red S, and Calcein for bone fluorescent labelling, After the experimental period of 16weeks, the dogs were sacrificed and tissue samples around the implants were obtained. Microscopic observations(ligth, polariged and fluorescence microscope), morphometric analysis, line profile with EPMA, and quantitative analysis for Ca,P, and Ti were performed. The results were as follows ; 1. Bone maturations around the implants were relatively lower than those of natural teeth. No significant differences in bone maturation and remodeling patterns were observed between the two implants groups. 2. Calcification of bone surrounding the implants was initiated in 8-11 weeks for HA-coated implants, while it took 11 weeks or more for Ti-coated implants. 3. Bone-to-implants contact ratio of 82.63% was recorded for HA-coated group and 72.25% for titanium coated group, with no significant difference between the two groups. 4. Bone around the implants exhibited reduced quantity of Ca and P in the $100{\mu}m$ region relative to natural teeth, while the rest of the regions showed no statistical differences. No significant differences were found between the two implant groups. 5. There was a separation of HA layer from the implant core and subsequent infiltration of inflammatory cells into the resulting space in the HA-coated implants, and evidences of phagocytosis of HA particles by macrophages. Bone calcification was more rapid around HA-coated implants compared to titanium-coated implants, but HA coated implants did not show any significant differences either in the degree of calcification or the bone-to-implant contact ratio over Ti coated implants. HA coated implants may have complications associated with HA absorption and separation of HA layer from the implant core.

본 최근 영상 및 멀티미디어의 시각적인 내용을 기반으로 하는 검색 방법에 관한 많은 연구들이 진행되고 있다. 내용 기반 영상 검색(content-based image retrieval)에 관한 대부분의 기존의 질의 방법은 입력 영상에 의한 질의 또는 컬러(color), 형태(shape), 특징(texture) 등과 같은 low-level 특징을 사용한다. 그러나 이러한 방법들은 비교적 사용하기 불편하고 방법이 편중되어 있어서 일반 사용자들의 다양한 질의 요구에 적합하지 못하다. 본 논문에서 제안하는 것은 내용 기반 영상 검색 시스템 하의 컬러 객체의 자동 추출과 다중 질의를 위한 레이블링 알고리즘이다. 이것은 먼저 single colorizing 알고리즘을 사용하여 영상의 영역을 단순화 시키고 제안하는 Color and Spatial based Binary tree map (CSB tree map)을 이용하여 컬러 객체를 추출한다. 그리고 제안하는 레이블링 알고리즘을 이용하여 데이터베이스의 객체들을 색인한다. 이것은 컬러와 공간 정보를 고속으로 레이블링 하고 객체의 컬러 속성과 크기 및 위치 정보를 이용하여 객체의 컬러 기반과 공간적 기반의 조합을 바탕으로 하는 사용자의 다양한 질의에 부합할 수 있는 적응성 있는 시스템을 구현한다. 본 논문에서는 "Washington" 데이터베이스를 이용한 비교 실험을 통해서 제안하는 시스템의 검색 결과의 우수함을 알 수 있었다.
