In an effort to evaluate the currents in pesticide residues, 3,020 agricultural products were tested by multiresidue method with 260 pesticides, obtained from the circulation market of in the Gangbuk province in 2007.20.4%(616/3020) of the products were determined to contain pesticides residues, but only 4.1%(124/3020) of these were deemed to be unsuitable by the korea Food Code. Unsuitably products were spinach(21.0%), perilla leaf(17.3%), ulgari(13.6%), leek(12.4%), crowndaisy(12.4%), asterscaber(12.4%), chard(11.1%). Detected pesticides were procymidone(3.9%), endosulfan(2.6%), chlorfenapyr(2.2%), bifenthrin (1.3%), cypermethrin(0.7%), metalaxyl( 0.9%), azoxystrobin(0.3%) and chlorothalonil(0.7%). Sixty-four pesticides were detected and 11 pesticides were newly detected in 2007. Thirty-one pesticides in agricultural products exceeded their MRLs.

The principal objective of this study was to evaluate the sanitary management status of chlorine sterilization methods used for raw fruits in a school foodservice, and to suggest basic data for sanitary improvements in the quality of raw fruits. A questionnaire form predicated on HACCP standards was developed and utilized for self-reported evaluations of dietitians regarding their sanitary management practices. The subjects consisted of 257 dietitians that were employed in school (elementary middle high school) foodservices. The collected data were analyzed with the SAS package. According to the results of this study, it was deemed necessary that optimized sterilization and washing methods for good microbiological safety and quality of strawberries and bananas in school foodservice should be determined. Some strategies for future improvement were also suggested. They included the following: (1) Improvement of policy for assuring the quality of raw fruits by designing some sanitation standards and specifications for raw fruits; (2) Strengthening the research and accumulation of background data regarding methods for the sanitation of raw fruits; (3) Enforced improvement of personal hygiene for dietitians and employees; (4) Use of a variety of methods in sanitary education and employee training.

The principal objective of this study was to assess the bone density and processed food intake behavior of middle-aged and elderly women in the Seoul area. The subjects were assigned to one of the following groups on the basis of BMI: namely, the underweight, normal, and overweight groups. The results are summarized as follows: The average BMI and systolic blood pressure of the three groups were 19.0, 127.3 mmHg; 22.4, 132.8 mmHg; and 26.8, 136.1 mmHg respectively. The BQI and T-scores of the three groups were as follows: 56.6, -2.50; 62.3, -2.22; 66.0, -2.03 respectively. The bone status of the three groups, in terms of the percentage of normal and osteoporosis, were 9.5%, 52.4%; 8.3% 33.0%; and 8.8%, 23.6% respectively. We noted no significant differences in processed food intake (frozen, cold and can processed food, instant and convenience store food, basic side dishes) behavior among the three groups. However, we recorded a negative value between processed food intake and bone density (BQI, T-score, %young adult, Z-score, %age-matched) generally. In particular, ramyeon (r=-0.1574, p<0.05) and cup-ramyeon (r=-0.1996, p<0.05) intake were significantly associated with the T-scores of bone density levels. The results of this study revealed that processed food intake was not generally desirable for healthy bone. Thus, practically and systematically organized education regarding a good and healthy dietary life is highly recommended.

Somatotype is a very important factor for the comfortable and safe work environments. Many researches are trying to find the characteristics of somatotype according to age. Thus, the main objective of this study is to analyze somatotype of male residents in Seoul. The data used in this study included 267 men subjects who are living in Seoul. In order to analyze a detailed somatotype of citizens, age groups are divided into six groups. In order to compare and analyze data, Coefficient of Variance, Cronbach's Alpha, Rohrer Index and Drop Value were used in this study. The results of this study can be applied to the comfortable and safe work environments for workers.

According to the measurements at Seoul Metro subway, the sound level at the time of subway arrival ranged from 77.0 to 92.5 dB(A). The highest level was 92.5 dB(A) at Line-1, and the lowest level was 77.0 dB(A) at Line-5. The sound level of departure ranged from the lowest level of 82.9 dB(A) at Line-5 and the highest level of 95 dB(A) at Line-1. The indoor sound level at subway ranged from the lowest level of 87.2 dB(A) (Line-6) to the highest value of 92.1 dB(A) (Line-1). The results of this study also showed that the sound level at subway platform with Platform Screen Door(PSD) showed 81.8 dB(A) but 89.1 dB(A) without PSD. The sound reduction effect of PSD showed 7.3 dB(A) at platform. Consequently, the sound level in Korean subway was found to exceed the standard set for the American Public Transportation Association (85dB(A)).

In order to investigate phenotype and genotype of Salmonella enterica subsp. enterica serovar Enteritidis, Forty-eight S. Enteritidis isolates from diarrhea patients were analysed using antimicrobial resistance typing, Phage typing, and Pulsed field gel electrophoresis in Seoul from 2004 to 2005. All of S. Enteritidis were resistant to streptomycin(SM, 37.5%), ampicillin(AM, 43.8%), t icarcillin(TIC, 43.8%), chloramphenicol(CM, 29.2%), t etracycline(TE, 10 .4%) and nalidixic acid(NA, 18.8%) among 16 antimicrobial drugs. Of 48 S. Enteritidis, 8 isolates(16.7%) were resistant to 1 drug, 3 isolates( 6.3%) to 2 drugs, 1 isolate (2.1%) to 3 drugs and 17 isolates(35.7%) to 4 drugs. The basic pattern of 4 drugs resistance was SM, TIC, TE, and CM but 1 drug resistant isolates represent all nalidixic acid resistance. Among 30 antibiotic r esistant S . Enteritidis, 2 1 isolates(70 %) were phage type 2 1, 8 i solates(26.7%) were phage t ype 2 3 and 1 isolate( 3.3%) was RDNC, respectively. Of the phage types observed, all of phage type 23(8 isolates) were nalidixic acid resistant and phage type 21 were AM-TIC-SM-CM multi-resistance(13 isolates; 43.3%), AM-TIC-SM-TE(4 isolates; 13.3%), AM-TIC-SM(1 isolate; 3.3%), AM-TIC-CM(1 isolate; 3.3%), and AM-TIC(2 isolates; 6.7%) resistance and 1 isolate of RDNC was NA-TE resistance. PFGE divided the isolates into two major clusters, A(n=14) and B(n=14). There were four different resistance profiles with resistance to AM, TIC, SM, TE, NA within PFGE A. Also resistance to AM, TIC, SM, CM was common within PFGE B. The PFGE A strains typed as PT21(n=5), PT23(n=8), and RDNC(n=1), While all the PFGE B strains typed as PT21(n=14). In consequence, there was the highly significant concurrence between resistance typing, phage typing and PFGE.

In order to investigate the resistance patterns and molecular characteristics of resistance gene of 9 NA-resistant Salmonella enterica subsp. enterica serovar Enteritidis, Total of 101 isolates were isolated from stool sampes from 2005 to 2006. Among them, 48 isolates(47.5%) were identified S. Enteritidis, 24 isolates(23.8%) S. Typhi, 8 isolates(42.5%) S. Typhimurium, 7 isolates(6.9%) S. Paratyphi A and 14 isolates (13.9%) others Salmonellas. All of S. Enteritidis were resistant to ampicillin(43.8%), ticarcillin(43.8%), streptomycin(37.5%), chloramphenicol(29.2%), tetracycline(10.4%) and nalidixic acid(18.8%), respectively. All nalidixic acid-resistance isolates represented one point mutation in the quinolone resistance determining region(QRDR) of gyrA gene. Among them, 8(89%) isolates were substituted Tyr for Ser at position amino acid 83th or 1(11%) isolate was substituted Asn for Asp at position amino acid 87th. In consequence, Continued surveillance of NA-resistance among non-Typhi S. entetica isolates is needed to mitigate the increasing prevalence of nalidixic acid resistance.

1996년 천호대로 중앙버스전용차로가 시행된 이후 2008년 까지 8개 구간이 운영되고 있다. 그러나 중앙버스전용차로의 시행에 따른 직 간접적 영향권 내의 도로교통량 변화는 보고되지 않고 있다. 따라서 본 연구에서는 2004년 7월에 동시 개통된 3개 구간에 대한 사전 사후 도로교통량 변화를 분석하였다. 분석결과, 중앙버스전용차로 구간의 교통량은 중앙버스전용차로 개통 후(2004년 11월) 24.7%로 급격히 감소한 후, 개통 후 1년(2005년 11월) 1.4%로 안정화 된 것으로 분석되었다. 인접 우회도로 교통량은 개통 후(2004년 11월) 2.9% 감소한 후, 개통 후 1년(2005년 11월) 0.3%로 미비하게 증가하였다. 측정오차(±5%)를 고려하면 중앙버스전용차로 교통수요는 안정화 단계에 들어섰으며, 자동차 수요가 인접지역으로 우회하기 보다는 타 수단으로 전환된 것으로 판단된다.

The objective of this study was to use cluster analysis to determine differences in eating-out behavior among grouped clusters of female consumers after each cluster was divided based on lifestyle patterns. The data were collected by interview survey from a biased sample of 1,300 females, ranging from ages 20 to 59, and living in residential districts of Seoul. Reliability analysis, factor analysis, cluster analysis, cross-tabulation analysis, and analysis of variance (ANOVA) were applied to the data. Four lifestyle factors were extracted by lower-division and classified as follows: health condition, consuming, food, and housing lifestyles. Based on these four factors, the female consumers were grouped as three clusters: the consuming-individuality type, rational-pursuit type, and conservative-stability type. The eating-out behavior of each cluster was significantly different in terms of frequency of eating-out, eating-out expenditures, restaurant selection criteria, food preferences, and the purpose for eating-out. Since this study surveyed females from ages 20 to 59, age and demographics were the differential factors in determining the various lifestyle types. Thus, to target the consumers who form a target market, the food industry should consider market segmentation that combines demographic factors such as age, income, and marital status.

본 연구는 서울시내 도림천, 방학천, 성내천, 양재천 일부구간을 대상으로 도시하천의 식생회복을 위한 기초자료 구축을 통해 횡단구조를 유형화하고 유형별 식생분포 특성을 규명하고자 하였다. 도시하천 횡단구조는 제방형태(수직형, 사면형)와 둔치 유무, 호안구조의 3가지 항목을 조합하여 사면형 56개 유형, 수직형 31개 유형으로 구분되었다. 대상지내에서는 SB1(저수호안-자연형 식생호안, 고수호안-자연하안), SG5(저수호안-콘크리트, 고수호안-사석공) 유형을 비롯한 사면형 9개 유형, VH4(제방호안-찰쌓기), VH7(제방호안-콘크리트) 유형 등 수직형 3개 유형이 도출되었다. 이 중 저수호안과 고수호안이 모두 콘크리트로 정비된 SG7 유형과, VG7 유형이 가장 긴 구간에서 분포하였다. 주요 8개 유형에 대한 미지형구조 및 식생구조를 조사 분석결과 유형화 항목별 특성에 따라 횡단구조가 식물생육에 미치는 영향을 파악할 수 있었으나 횡단구조 유형별 식생분포 특성은 뚜렷치 않았다.

Seoul has been watched at its symbolic image which is the capital of one nation. since then Joseon was established. So, most of study about Seoul placed too much emphasis on like next; urban organization, palace, government office and public establishment. On the other hand, it is lacking in study of the individual building, the residential district, the change of building-lot. This study is to make up a deficiency from study of Gaokdohyung(家屋圖形site and floor plan). Gaokdohyung(家屋圖形) is drawings of building lots & houses existed in Hanseongbu漢城府(modem Seoul). It is possessed in Jangseogak and all 24 sheets. It is merely 24sheets but has many urban information in that. Housing of number 116 expressed in Gaokdohyung are consist on the house of Sadaebu士天王(noble class) Joongin中人(middle class) Sangmin常民(commoner), Villa(Byeolseo別墅) and connecting stores etc. Houses in Gaokdohyung has characteristic that most building lot is very specious and owners are variety of social position. The study of Gaokdohyung will progress through analyzing diachronic change of individual building lot & house. In the event, results of this study will help to find out change of urban tissue & architecture. So, i intend to seek for entity of urban tissue and urban house in Joseon Period differ from now, and to study out those have been changed continuously forward now.
