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.

The objective of this study was to investigate a method to improve and to increase the utilization of Korean traditional food in middle school students by examining preferences and perceptions. Middle school students in Seoul area were surveyed from 29 November to 6 December 2007. The results are summarized as follows: 83.9% students ate Korean food as breakfast. The reasons for the success of Korean food were 'Nation's traditional food' (29.2%), 'fit in taste' (27.4%), and 'suitable match of nutrients' (24.8%). Students responded that the following needed to be changed in order to improve Korean food: 'alleviation of strong taste' (30.3%), 'various cooking methods' (23.9%), and 'convenience of eating the food' (22.1%). Meal preferences in this survey of middle school students were 'Korean food' (4.09), 'Western food' (4.08), 'Japanese food' (4.00), 'Chinese food' (3.91) and 'Fast food' (3.55). Perceptions in the taste of Korean food were 'spicy taste' (3.28), 'hot taste' (3.22), and 'salty taste' (3.15). Male students (3.23) perceived a higher salty taste than female students (3.05). Expectations for the taste of Korean food included 'spicy taste' (3.16) and hot taste (3.03). Male students (3.25) anticipated the spicier taste more than female students (3.05).

우리나라 온대지방 산림의 극상수종으로 알려진 서어나무는 도시화가 심각한 서울의 경우 3개의 군집이 분포하고 있는 것으로 알려져 있다. 본 연구는 희귀하게 분포하는 서울지역 서어나무군집의 특성을 도출하고, 이를 바탕으로 서어나무군집의 관리대책을 마련하기 위한 기초자료 제공을 목적으로 수행되었다. 연구 대상지는 삼육대 지역, 도봉산 지역, 진관동 지역의 3개소이다. 서울 지역 서어나무군집에 대한군집구조 분석 및 토양특성, 수목 생장량 등을 조사 분석한 결과, 현재 남아있는 서어나무군집의 경우 토양 산성화 등으로 인해 생장 속도가 둔화되고 있는 것으로 분석되었다. 또한, 산림내 외래종의 이입에 따른 식생교란도 진행되고 있는 것으로 나타났다. 서울 지역에서 가장 넓은 서어나무군집이 분포하는 삼육대 지역의 경우 주변 참나무림에 참나무시들음병 피해가 발생하여 산림내부에 나지가 발생하고 있고 외래종의 이입속도가 더욱 빨라질 것으로 예상되고 있다. 또한 서어나무 자체도 참나무시들음병 매개곤충인 광릉긴나무좀의 피해를 받고 있어, 특별한 대책이 수립되지 않는 한, 향후 서어나무군집의 존립 자체가 불투명한 실정이다. 따라서 현재 남아있는 서어나무군집에 대한 정밀조사와 연차적인 모니터링 등과 같은 대책을 마련하여 서어나무군집 보전을 통한 서울지역 생물다양성 확보 방안의 추진이 필요하다.

This studyevaluates the effectiveness ofthe “ Seoul Sanitation Grading System Evaluation Index" devel0ped earlier and to analyze sanitation management practlces in restaurants in Seoul, Korea. The categories evaluated were the food management standard, facilities/equipment standard, and essential checking items specified in the law. These items were graded and classified into A (100~90)， B (89~80)， C (79~ 70) and Score (less than 69) based on the criteria set by the present researchers. We randomly selected 56 restaurants in five l0cal cities (Jung-gu, Seocho-gu, Jongno-gu, Songpa-gu and YIeongdeungpo-gu) and investigated each by actually visiting the site of business. The achievement rate for food management standard was 80.8%; as for the specific items in the category, it was the highest in food ingredients at 77.1 % and the lowest in food storage at 62.1 %. For the facilities/equipment standard, the achievement rate was 77.8%; as for the specific items in the category， it was the highest for vermin at 88 .1 % and the lowest for operation at 70.8%. The achievement rate for overall individual sanitary management was 70.7% and in the category, the lowest score was seen in hand washing at 57.1 %. The overall average score of sanitation management practices using the Seoul Sanitation Grading System Evaluation Index in restaurants in Seoul was 73.7, which fell into the C category. As for the number of restaurants in each grade category, there were 10 (17.9%) in each category of A (100~90), B (89~80) and C (79~70) with 30 (53.6%) scoring higher than 70, whereas those scoring less than 69 included 26 (46.4%). The average scores for those restaurants designated by local governments (exemplary restaurants, general restaurants, best Korean restaurants in Seoul) were not significantly diffierent; however, they were higher in franchises than those small restaurants ran by individuals.

외부환경 변화와 천이의 영향으로 쇠퇴현상이 나타나고 있는 서울시 소나무림의 식생환경을 개선하고자 교목층 우점종의 경쟁관계, 하층식생내 경쟁종 출현 유무, 관리정도 등에 근거하여 유형을 구분하고 생태적 관리방안을 제안하였다. 서울시 소나무림을 생태적 특성에 따라 분류하면 소나무순림에 속하는 토지극상림(26.1%)과 소나무순림(21.5%), 소나무와 타 수종이 경쟁하는 소나무-신갈나무림(28.0%), 소나무-리기다소나무림(13.1%), 소나무-상수리나무림(4.2%)등으로 구분되었다. 이들 유형에 대한 정밀한 식생조사 결과, 토지극상, 답압피해, 식생관리로 인해 교목층과 하층에 경쟁종이 출현하지 않아 소나무림 유지가 가능한 4개 군집은 하층식생 보완 등 소극적인 관리가 필요하였다. 반면 교목층과 하층에 소나무와 경쟁수종인 낙엽성 참나무류와 외래종이 출현하는 4개 군집은 생태적 지위가 동일한 경쟁종관리, 하층식생 도입 등 적극적인 관리기법을 적용해야 소나무군집을 유지할 수 있을 것이다.

This study was carried out to investigate the current status of suspected endocrine disrupting pesticides among the agricultural products in northern area of Seoul in 2007. 3,026 samples was analyzed by multiresidue method. Detected Pesticide in 11 cases were procymidone, endosulfan, chlorothalonil, chlorpyrifos, cyermethrin, fenvalerate, hexaconazole, carbendazim, pendimethalin, permethrin, parathion and exceeded 7 cases of endosulfan, procymidone, carbendazim, chlorothalonil, chlorpyrifos, cypermethrin, fenvalerate in the maximum residue limits(MRLs). Procymidone, endosulfan, chlorothalonil and chlorpyrifos comprised up to 80.5% in detected pesticides. Among the 321 cases of detected agricultural products, 287 cases(89.4%) were vegetables, 25 cases (7.8%) were fruits, Others were 9 cases(2.8%).

본 연구는 교통사고의 발생 유형과 교통사고 심각도(Severity)와의 관계를 규명함으로써 위험유형을 제시하고, 운전자 특성과 교통사고의 관계를 규명하고자 하였다. 교통사고 유형을 여덟 가지로 세분하고, 결과의 객관성 확보를 위해 안전벨트 착용여부를 추가하여 상해정도와의 관계를 분석하였으며, 위험그룹의 분류를 위한 운전자의 특성은 성별, 차종, 연령 등을 대상으로 하였다. 카테고리 자료의 분석을 위하여 로그-선형 모형 및 로짓 모형을 사용하였다. 분석결과 사고유형과 심각도와의 관계에서는 정면충돌 사고와 앞지르기시, 우회전시 사고가 부상 또는 사망사고에 연루될 가능성이 높았다. 위험그룹 분석에서는 20세 미만의 이륜차 운전자, 41세에서 50세까지의 택시 운전자가 가장 위험한 집단으로 분석되었으며 또한 남자보다는 여자가 승용차와 중형화물 등에 관계되었을 때 더 위험한 것으로 분석되었다. 따라서 교통사고 발생시 인명 피해를 줄이기 위해서는 정면충돌 사고와 앞지르기시, 우회전시 발생하는 사고를 줄일 수 있는 방안이 연구되어야 하고, 교통사고 취약계층으로 분석된 위험그룹에 대한 교통안전 교육 및 단속이 강화되어야 할 것이다.

The susceptibility of the Blattella germcanica (L.) in the Republic of Korea (ROK) to insecticides was evaluated under laboratory conditions using 12 insecticides currently used by the local public health centers and/or pest control operators in the ROK. The insecticides included seven pyrethroids and five organophosphages. Based on their LD50values, the order of susceptibility of B. germanica adults to the insecticides was chlorpyrifos-methyl, profenofos, and chlorpyrifos with the values of 0.07, 0.29, and 0.88 ㎍/♀, respectively. The least susceptibility was obtained with tetramethrin at LD50 of 7.39 ㎍/♀. In the comparative resistance test, the resistance ratios (RR) of 12 insecticides were compared to each other using field collected B. germanica adults in Seoul between 1993 and 2007. Blattella germanica demonstrated higher RRs to pyrethroids such as λ-cyhalothrin, and low RRs among the organophosphates. Among the pyrethroids, λ-cyhalothrin had the highest RRs of 111 and 129 fold differences at LD50 and LD90 values, respectively. Among the organophosphates, profenofos was observed to have the highest RRs of 4 and 15 fold differences at LD50 and LD90 values, respectively. However, there were no significant differences in susceptibility to tetramethrin, chlorpyrifos, and fenitrothion. Blattella germanica was more susceptible to pyridafenthion showing a 0.7 fold difference in a resistance rate (RRLD50), respectively. Resistance ratio of tetramethrin was low, but susceptibility was also not high.
