On the basis of the results above, many seasoned dried fishes had multiple drugs resistances, conclusively, we suggest limited guideline and special management on use of antibiotics in floating net cages of fishery farms.

In this investigation, 480 high school students attending school in Seoul, Incheon were surveyed for their knowledge of seaweed and their preference of seaweed products provided during school meal service. Female students answered that they preferred seaweed more than male students. When asked to explain their preference for seaweed, most students who preferred seaweed responded ‘it is tasty’ (82.9%), while those that did not like seaweed responded ‘I don’t like the texture when chewing it and it is not tasty’ (47.8%). Most students reported that they usually eat ‘laver’, and the number of times that they at seaweed was ‘3-4 times a week’. The primary place in which they ate seaweed and the place where they feel it had the best taste was a ‘house’. The primary source of information regarding seaweed was mass media including TV, newspapers, magazines and the internet (48.8%). With regard to seaweed in school meals, which is offered twice a week, most students reported, ‘I eat seaweed and leave it to some extent.’ They perceived ‘laver’ to be most often provided in school meals, and 57.7% reported that their favorite seaweed meal was ‘laver’. When asked why they dislike seaweed in school meals, the most common responses were ‘I didn’t like seaweed the first time I tried it’ (27%) and ‘Its taste is different from what I eat at home’ (24.6%). The most common request regarding seaweed provided in school lunches was for the taste to be improved (48.2%). Evaluation of the preference for seaweed menus in school meals revealed that both males and females had higher preferences of more than 4 points for ‘fried laver’ and ‘broiled laver’.

In this study, the symbols and visual expressions employed in the food culture content of official website designed to promote three cities in Korea, Seoul, Jeonju and Jeju, were subjected to semiotic analysis. In this study, it was assumed that these websites reflected the varying perspectives of the people behind the development and management of these routes of Internet communication, and the semiotic choices made in order to exemplify each city’s food cultural image. The aim of the study was to analyze the communication strategies of food cultural branding in the terms of the online content regarding Seoul, Jeonju, and Jeju with a focus on the comparative points in these cities’ official websites. This study included conducting semiotic content analyses of the aforementioned cities’ official web pages in an attempt to determine the food branding strategies used to differentiation and produce more favorable perceptions of these three cities. Building upon the findings drawn from this comparative study, the present work can be used to determine more effective ways of strategically differentiating the images of local food culture associated with these cities from the view of brand communications. This study also demonstrates viable directions for designing web content for a city where the food cultural messages can be delivered in a thoughtful and effective manner.

This study was carried out to investigate the current status of pesticide residues in 3,735 agricultural products in the northern area of Seoul from January to December in 2008. 3,735 samples, comprising 119 types of agricultrural products were assessed via a multiresidue method to detect 260 pesticides. Pesticide residues were detected in 19.7%(737 of 3,735 samples), and the rate at which the detected residues violated the maximum residue levels(MRLs) of the Korean Food Code was 3.2%(121 of 3,735 samples). Pesticide residues were detected in 72 spinaches, 64 peppers, 45 sweet peppers, 40 perilla leaves, 38 korean cabbages and 37 dried agricultural products. The samples that violated the MRLs included 14 perilla leaves, 13 spinaches, 12 leek, 6 lettuces(leaf), 6 chards and 6 gyeojchaes. Procymidone, endosulfan, chlorfenapyr, cypermethrin, bifenthrin, tebuconazole and fenvalerate were all frequently observed. Procymidone, endosulfan, dimethomorph and diniconazole were the pesticides most frequently detected at levels that violated the Korean Food Code MRLs.

This study was carried out to evaluate the consumer recognition with regard to the safety management for imported foods. In order to evaluate the effect of the prgram on consumer education, the program was practiced for 89 female college students in Seoul, Korea. The participants were given an instruction with materials on imported food safety, including the safety management of imported foods and their distribution. The results showed that the participants achieved a greater understanding of imported foods. In particular, they had firmly grasped the importance of expiration date in selecting imported foods. Before the instruction, 50.6% of total participants blamed the Korean government for the problems arising from imported foods; only 18.0% placed the blame on individuals or businesses importing from foreign countries. After the instruction, 39.3% had blamed the individuals or businesses importing from foreign countries. Furthermore, 36.0% had disapproved of the foods that are imported from China before the instruction, while 32.6% found objectionable the views on the illegally distributed foods; 29.2% criticized the junk foods that target children (after the instruction). In addition, the level of participant satisfaction via-a-vis imported foods safety supervision had improved from 2.76 ± 1.59(before the instruction) to 3.37 ± 1.58(after the instruction). The results indicate that consumers are concerned with the imported foods that contain adulterated or forbidden substances and the illegally distributed foods from foreign countries. Thus, consistent and informative educational programs on imported food safety could help consumers in choosing safer products, resulting in an improvement in the consumer confidence with respect to imported foods.

서울시와 베이징시의 두 도시의 공원 관리체계의 현황, 유형, 관리조직, 이용객, 예산, 문화활동 분야로 구분하여 정리하였고, 양국 비교분석 하였다.두 도시의 공원 관리체계의 기본기능과 내용은 대체적으로 동일하나, 그러나 구체적인 방면에서 차이가 많다. 공원녹지통계, 오락공원시설, 이용객 및 구성원의 신분 통계, 수입관리방식, 관리조직과 기능, 이용객을 끌어들이는 방식 및 관련있는 법규의 내용등 방면에서 나타난다.공원관리의 과정에서 나타나는 차이의 주요원인은 국가의 문화, 행정체제가 다른데 있으며, 목표에 도달하기 위하여 두도시 모두 많은 방면에서 노력을 하고 있으며, 시설의 재정비, 공원문화의 혁신 등을 통하여 이용객 만족도를 높이는 것이다.두 도시의 도시녹화, 공원시설, 이용객 활동, 구성원과 원림수입/지출방면의 통계자료로 두 도시의 특징과 차이를 보이고,도시공원의 문화활동, 입장료 판매방식, 수입/지출관리 방식을 비교하여 최종에 두 도시의 공원관리방식에 관련 있는 법규내용의차이가 나타났다..공원관리사업에서도 공통적으로 공원조성, 수목 및 화훼, 시설물 보수 및 정비, 환경위생, 공원 서비스, 유람 서비스등서비스가 포함되기 때문에 관리내용이 비교적 업무량도 많으나. 그러나 베이징시의 경우 공원 구성원들은 반드시 계획대로고효율적으로 공원관리를 진행하여 공원관리의 목적에 도달해야 하다는 인식이 지배적이다.그러나 비교할 수 있는 자료는 문화와 행정체계가 다르고 연구 자료도부족하기 때문에 내용도 한계가 있다고 보며, 중국의녹지 정책, 넓게는 중국의 환경개선 및 보호 정책에 대한 정보가 매우 부족한 상태이므로 정책과 실상을 알아보는 것이가장 우선되어야 할 것이다.

Seoul is one of the most dynamic capital cities in the world of which population is about 10.49 million. The air quality of Seoul subway is a great concern to users and the public authorities, especially the pollution of particulate matters. The metallic particulate matters are generated from the friction of wheels and subway rails, which causes dispersion into the platform and even to the trains. This study attempted to characterize the current filters in subway MVAC system and a newly developed filter which was a type of thin electret fiber bundle. Collection efficiency of the filtration system varies from 20% to 90% depending on filter life and dust particle size. The removal of fine dust with diameter smaller than 1㎛, which could not be well achieved by current filtration system, is very important in the subway air cleaning system. The new electret filter was found to have a high potential for the use in subway MVAC with high collection efficiency, especially for fine mode dust.

This study investigates H-shaped houses in 1930s and examines the characters and meanings of Kim, Jong-Ryang`s H-shaped houses as a new trial to urban Hanok of those days. He, who was concerned about the housing problem of Seoul, made an attempt to make various types of dwellings. Among them, this study focuses on Japanese-Korean Style H-shaped houses in Samcheong-dong. As the alternative housing type against other urban Hanok of Seoul in 1930s, the H-shaped houses of Kim, Jong-Ryang had characters as follows : 1) H-shaped house has two special characters. First, the whole space of a single house can be divided into a left region and a right region. Second, it can be divided to a front region and a rear region. In his H-shaped houses, the left/right division was expressed as folding of space-layers in parallel with urban streets. The front/rear division was used as classification of main-living space and sub-living space. 2) KJR`s H-shaped Japanese-Korean Style houses were proved to be designed as urban housing against the extreme housing shortage of Seoul in 1930s. 3) His houses however were not accepted broadly as a urban house type because the construction cost of those was higher than an average and the element of Japanese style house was not adapted to Korea. Kim, Jong-Ryang`s trial is valuable because it was the rare case of realization of many discourses as defects of existing house type. With more rigorous investigations on KJR`s experiment in modern house type, we could understand the housing condition of Seoul in 1930s and modern urban houses more than before.

Currently food-borne disease is being increased at outdoor food services including hotels and restaurants. Speedy and convenient practical monitoring techniques to determine hygienic conditions are needed. This study was designed to verify correlation of direct ATP (Adenosine Tri-Phosphate) examination method using ATP bioluminescence and surveillance with check-list by inspector. Hygienic status of personal hygiene (hands), kitchen utensils (knives, chopping boards, kitchen towels, cap openers, food storage containers, and blade of slice machines), facilities and equipments (refrigerator handles, worktables, and sinks) in five major hotels in Seoul were examined. The result of personal hygiene of hotels was relatively better than other inspection items (46.6 points in personal hygiene, 40.2 points in kitchen utensils, 40.3 points in facilities & equipments). In ATP inspection, kitchen utensils and facilities & equipments were relatively clean comparing with personal hands data (40.8 ± 6.77 RLU/cm²). After correlation analysis of surveillance in hygienic status points and ATP value, all results showed negative and high correlation. The surveillance data and ATP results investigating personal hygiene, kitchen utensils and facilities & equipments were highly correlated. The ATP examination method which shows real-time identification could be considered as an appropriate method to alternate current check-list dependent safety management in food services including hotels.
