This study was to investigate the food habits and the dietary behaviors of university students. Questionnaires were completed by 492 students in five different departments. The data were analyzed by SAS program. The results are summarized as follows: Fifty(10.2%) of respondents were vegetarians, 81(16.4%) were heavy meat eaters and all the others were light meat eaters. All students had their biggest meal at supper. Three hundred and ninety-three(79.9%) of the respondents usually had rice for breakfast. Three hundred -sixteen(64.2%) ate 3 meals a day, 155(31.5%) ate 2 meals and all the others ate 1 meal or more than 3 meals. The length of mealtime was 30 minutes in 268(54.5%), 10 minutes in 209(42.5%) and more than 1 hour in all the others. Respondents considered taste the most important meal factor with nutrition, hygiene, and amount ranked accordingly. A majority(63.0%) of respondents ate occasionally ate between meals, while 28.1% snacked frequently, and 8.9% ate no snacks. Although nutrition dept. students had studied nutrition subject, some results of nutrition dept. students were desirable and others were undesirable in dietary behaviors. Therefore they should have a nutritional education program to improve their food habits and the dietary behaviors for students' health. And nutritional education program should be organized practically and systematically.

The purpose of this study is to investigate children's satisfaction with side dishes served in elementary school food service program in Seoul area. Two hundreds and thirty two children participated in this study through a questionnaire developed by the researchers. Conclusion drawn from the results of this study is that there seems no significant problems in school food service program since children are generally satisfied with food provided by school. However, minor problems such as hot and salty food, inappropriate temperature of warm dishes, and excessive amount of food, need to be improved through a newly developed menu, cooking method, and food distribution method.

This study was concentrated that the contents of heavy metals were estimated from 782 samples of sold fisheries in Seoul(33 species in fishes, 15 in bivalves, 12 in crustaceans and 10 in others) by Atomic Absorption Spectrometer. The contents of As, Cd and Pb [minimum-maximum (mean)] were N.D.-0.162 mg/kg(0.021), 0.001-0.120 mg/kg(0.014) and 0.015-0.499 mg/kg(0.111) in fishes, 0.003-0.311 mg/kg(0.052), N.D.-1.905 mg/kg(0.182) and 0.013-0.462 mg/kg(0.138) in bivalves, N.D.-0.328 mg/kg(0.042), 0.002-1.113 mg/kg(0.079) and 0.006-0.510 mg/kg(0.109) in crustaceans, N.D.-0.181 mg/kg(0.024), 0.001-0.214 mg/kg(0.033) and 0.010-V0.877 mg/kg(0.118) in others respectively, bivalves were the highest than others. The average weekly intakes of three metals from sold fisheries took about 1.4-26.4% of PTWI (provisional tolerable weekly intakes) that FAO/WHO Joint Food Additive and Contaminants Committee had set to evaluate their safety.

The purpose of this study was to compare nutritional intakes of college students in Seoul and Yanbian by ethnic : Korean, Korean-Chinese, Chinese. The questionnaire were applied to individual interviewing method. Statisticai data analysis was completed by SAS 8.0 package program for t-test, ANOVA and multiple comparison. The results of this study were as follows. Average energy intake per day was high in Korean-Chinese. Nutrient Adequacy Ratio(NAR) was highest in iron and lowest in zinc. Mean Adequacy Ratio(MAR) score was 0.68~0.85 for each group. The indexes of nutritional quality(INQ) were over 1.0 for most nutrients except 0.41 of zinc and 0.76 of calcium. Average energy intake ranked high in Korean-Chinese, Korean and Chinese.

The facts of job satisfaction and their perceived importance among elementary school foodservice dietitians were assessed. The survey instrument consisted of three parts: the job satisfaction survey was used to measure facets of job satisfaction and the level of total satisfaction; perceived importance questions for corresponding job facets; and demographic items. A survey of school food service operations was undertaken and detailed information was collected from 170 dietitians. The collected data were processed using the SPSS package program for descriptive analysis and analysis of valiance. School foodservice dietitians' importance and satisfactions scores on their job and working environment were 4.25 and 2.83, respectively. The respondents rated the subscales of 'communication' and 'nature of work' the highest and the subscales of 'pay' and 'working environment' the lowest The results of facet satisfaction scores and corresponding perceived importance scores were paired to be plotted on the Importance-Performance Analysis Grid. IPA grid was used to provide a strategy for food service managers to counteract dietitian dissatisfaction.

Imported area as well as domestic area samples should be strengthen to examine enduringly.

본 연구에서는 서울 소재 초등학교와 고등학교 급식의 위생관리 실태를 분석하므로 학교급식의 안전성을 확보하여 식중독 사고예방 및 급식품질 개선을 이루고자 하였다. 이를 위해 HACCP에 기준한 위생관리 평가도구를 설문지로 개발하여 관리자들이 자가 평가하게 하고,그 결과를 분석하여 위생관리 실태를 파악하고 취약한 부분을 규명하였다. 위생관리 평가도구는 온도 소요시간, 개인위생 및 기기 설비위생의 3영역으로 구분 하여 33문항, 5문항, 15문항씩 총 53문항으로 구성하였다. 평가문항에 대해서는 5점척도를 이용하여 표시하도록 하였다. 조사된 학교는 초등학교 98.4%(253개교), 고등학교 1.6%(19개교)였다. 세 영역중 개인위생에 관한 수행수준은 평균 4.06$\pm$0.57로 나타나 가장 잘 수행되는 것으로 조사되었다. 기기.설비위생의 수행수준은 평균 3.84$\pm$0.53로 나타났고, 온도.소요시간은 평균 3.45$\pm$0.46으로 나타나 보통정도의 수행수준으로 조사되었다. 특히 전체 문항중 수행수준이 가장 낮은 것으로 조사된 ‘조리 후 보관(2.03$\pm$0.94)’의 경우는 현행 학교급식업체들이 조리가 끝난 식품을 취급할 열장 또는 보온 기기, 냉장고를 거의 구비하지 못하고 있으며, 조리된 음식이나 차게 배식하는 음식의 적정 온도유지를 위한 온도계 사용이 전혀 이루어지지 않고 있기 때문인 것으로 사료 된다. 기기 설비위생영역에서 가장 낮은 수행정도를 보인 ‘싱크대의 용도별로 분리사용 여부(3.03$\pm$1.10)’와 ‘손 씻는 시설의 적절한 장소 위치 여부(3.07$\pm$1.13)’의 수행수준을 향상시키려면 적절한 개수의 싱크대를 구비해야 하며, 조리실내에 손 씻는 시설을 갖추어야 할 것이다. 결론적으로 학교급식 안전성 확보를 위한 위생관리 업무 향상을 위해서는 본 연구에서 가장 취약한 부분으로 드러난 시설 및 기기들을 우선 보완해야 할 것으로 사료된다.

Staphylococcus aureus is gram positive, facultatively anaerobic, non-sporulative coccus, and positive for coagulase and DNase. The food oisoning outbrealc of Staphylococcus aureus increases in the world, and third occurnn happened in our country. Of 105 isolates (25.4%) obtained 413 fecal samples of food-poisoning suspicious patients. In those cases, the enterotoxins were detected firom a total of 45 isolates (42.9%), 9 isolates(20.0%) were A type, 33 isolates (73.3%) we H types, 2 isolates (4.4%) were G type and 1 isolate was a I type enterotoxin. Among the isolates possessing staphylococcal enterotoxins, 29 isolates had H type only(64.4%), 5 isolates had A type only and 4 isolates had both A and H type. 'Iieo isolates had G type only and 1 isolate had I type only. In the antibiotic susceptibility, 48 isolates (46%) had at least one antibiotic resistance among 105 isolates, 34 isolates (70.8%) were resistant to penicillin, 1 isolate (2.1%) to ampicillin, 3 isolates (6.3%) to erythromycin and kanamycin. Seven were resistant to more than two antibiotics and especially 1 isolate was resistant to penicillin-ampicillin-nitrofurantoin.

This study was performed to investigate the pattern of health food usage of the adults by food lifestyles pattern in contemporary Seoul. This study views health food consumption as a cultural practice in which people produce (and reproduce) diverse social relationships and cultural meanings. It also identifies food lifestyles and health food usage pattern of Korean adult in Seoul. This topics were discussed based on field research data collected by nutritional survey with questionnaire. To identify the relationships between pattern of health food and food lifestyles, 503 men and 437 women aged 18 to 65 years were divided into 5 groups of food lifestyles : Health Eaters, In-a-Dither, Traditional Eaters, Conscientious and People on the Go. As a substantial percentage of the subjects were used some kinds of nutrients supplement. The higher the age and family income were, the higher the percentage of health food usage was. There was the significant difference between sexes in usuage of health food. Health food usage was higher in the food lifestyle pattern of Health Eater than other food lifestyles.

1980년대 말 시점과 1990년대 말 시점을 비교구간으로 설정하여 서울 한남동지역에 대한 대기중 수은의 농도분포변화양상을 비교해 보았다. 긴 시간 동안 발생원과 소멸원이 지닌 관계의 변화와 같은 영향에 의해, 양 기간대의 농도분포는 절대적 및 상대적 관점에서 모두 뚜렷한 차이를 보여 주었다. 80년대말 시점의 농도가 14.4±9.56 ngm-3인데 반해, 90년대 말 시점에는 이보다 1/3 가까이 감소한 5.34±3.92ngm-3를 유지하였다. 두 기간대에 관측된 농도 및 주변환경변수를 여러 가지 주기별로 수은의 농도분포양상을 비교해 보았다. 24시간 주기 또는 계절별로도 양기간대의 농도분포는 뚜렷한 차이를 보여 주었다. 과거 시점에는 낮 시간대에 고농도가 발생하는 현상이 빈번한데 반해, 현 시점에서는 이러한 양상을 확인하기가 어려웠다. 또한 계절적으로 겨울철에 고농도가 집중되는 현상은 과거나 현재나 유사하지만, 과거의 경우 겨울철 고농도가 여타 계절에 비해 확연했던데 반해, 최근의 분석결과는 계절간 차이가 상당 수준 줄어 들었다는 것을 보여 주었다. 이들 자료를 이용하여, 여러 가지 통계분석을 실시한 결과, 양 기간대에 현저하게 차이가 나는 농도분포는 주로 각 기간대별로 수은의 농도를 조절하는 주생성원의 성격이 현저하게 다른 데 따른 가능성이 강할 것으로 사료된다.

1999년 9월부터 2000년 7월까지 서울시 한남동과 경기도 과천시 두 지역을 중심으로 대기 중 수은의 농도를 시간대별로 관측하였다. 두 지역의 여러 가지 여건 차이에도 불구하고, 양 지역의 농도는 각각 5.34(N=2576), 5.25ngm-3(N=1992)를 기록하였다. 본 자료를 이용하여 양 지역의 농도 분포 특성을 비교하였다. 24시간 주기로 볼 때, 한남동 지역은 야간대에 그리고 과천 지역은 주간대에 높은 강도를 띠는 것으로 나타났다. 계절적으로는 한남동 지역에서 겨울 그리고 과천 지역에서는 여름에 최고농도를 기록하였다. 양 지역에서 수은의 농도를 조절하는 요인을 여러 가지 통계적 기법으로 고찰하였다. 본연구의 결과에 의하면, 연구 지역의 대기중의 수은 분포는 지역적 발생원의 차이에 의해 크게 영향을 받는 것으로 나타났다.

In order to investigate the eating out behavior of university students, this survey was conducted using the questionaires for 710 students(369 male, 341 female) from 11 universities in Seoul. It was revealed that 39.4% of the subjects spent 60,000~100,000 won for monthly eating out cost and 57.8% of them ate out more than once a day. Most of them expended less than 3,500 won for lunch, while 36.5% of them spent 4,000 ~5,000 won for dinner. Dinner was regarded more important than lunch. Korean foods were the most preferred menu for eating out with friends and fast foods were the second. But Boonsik(snack bar foods), Chinese foods and Japanease foods were rarely selected. Frequency of selecting fast foods was 8 times greater than that of Boonsik. This indicates that the preference of western flavor and the pursuit of convenience is getting more obvious. While dating, western foods were preferred, followed by Korean foods, fast foods. The 80 kinds of foods were reported as favored eating out foods. Although 50 among 80 were Korean foods, the rest of them were Koreanized foreign foods most of those were western style. This may suggest that when the students become adults, they will be much fond of western dish for their dinning out. This tendency of preferring western flavor were much apparent in foods for dinner compared with lunch. In both sexes, the standard of food choice was in the order of taste, price, mood, hygiene, service and brand name. But male students were more conscious of price and service while female students were more concerned about taste and hygiene. Most unsatisfying feature in restaurant was unstable atmosphere for both sexes. Taste was the most important sensory factor in selecting the foods, followed by appearance, smell and texture. Major source of restaurant information was recommendation by friends or relatives. But the use of internet or magazine was negligible. Female students had more positive attitude, compared with male students, in using restaurant information and pursuing eating out for gourmet. The dining out menu of which price ranges about 3,000~5,000 won could be preferable foods for most people. Therefore, instead of blaming them for eating too much fast foods, new menus which fit the food preference and affordability of the students should be developed.

The purposes of this study are : (a) to investigate the attitude to various coffee and tea of women, (b) to analyze the characteristics of each classified group according to eating frequency, and (c) to abstract the factors which can influence the consumption of coffee and tea. Questionnaires were hand delivered to 1,200 women residing in Seoul. A total of 1012 was usable: resulting in 84% response rate. Statistical data analysis was completed using SAS Package program for the one way-analysis of variance(ANOVA), Duncan's multiple comparison test, factor analysis and analysis of covariance (ANOCOVA). (a) Instant coffee was most consumed(22.1 times a month), green tea in tea bag(8.7), Donggulre tea(8.3), Coffee (72) in order of frequency. Among Korean traditional tea Donggulre tea(8.3) and Yuja tea (2.0) were most prefered but still a minute quantity of Korean traditional tea was enjoyed. (b) Coffee and Black tea was regarded unhealthful but habitual, delicious and familiar beverage. Green tea was regarded good for health but not so habitual, practical and familiar. The consumer awareness can be grouped into 3 clases : Healthy factor, Habitual Practical factor, Familiar factor. (c) The sociodemographic characteristics of women influenced the beverage consumption. Women in their 30s and 40s consumed much of instant coffee and coffee. 10s and 20s consumed much of canned coffee. Working women drank much of instant coffee and green tea in tea bag. Women in highest income group(≥ 4,000,000 won/month) consumed much of coffee. (d) The factors which influenced the eating frquency of those beverages were various. The eating frequency of instant coffee was influenced by the age, familiar factor and habitual practical factor. And coffee were influenced by income level, habitual practical factor. The frequency of green tea in tea bag was influenced by habitual practical factor and familiar factor, green tea was influenced by healthy factor and habitual practical factor, Donggulre tea was influenced by habitual practical factor.

The purpose of this research is to compare the university foodservices with exterior restaurants, to investigate the fact regarding the use and the preference, to evaluate the expectation and the satisfaction of eaters, and to establish the foundation to improve the quality of the university foodservices. 2 women's universities were chosen and 300 copies of survey were distributed to the students. The data were statistically analyzed by SAS. The frequency was compared with the percentage by using Chi-square, and Spearman Correlation was calculated to see the correlation between the expectation and the satisfaction. The results of this research are as below: 1) As students move to upper grades, have enough monthly allowance, have irregular dietary habit and have snacks often and spend much time on eating, and as the BMI index is low, the survey shows that students use exterior restaurants more frequently than the university foodservices. 2) Analysis of main factor in utilizing university foodservices and exterior restaurants Is 'the taste', 'the price', 'the variety of menu'. 3) The survey also shows that the satisfaction is greater than the expectation for exterior restaurants while the satisfaction is not greater than expectation with the university foodservices. 4) The matters like 'more delicious-food' and 'more various menu' were pointed out to be improved.

대규모 면오염원으로 간주되는 난지도지역을 중심으로 2000년 봄 기간중 대기-지표간 수은의 교환율을 측정하고, 측정자료를 기초로 수은의 교환현상을 분석하였다. 측정결과에 의하면 난지도지역은 대규모 면오염원으로 대량의 수은을 배출할 뿐아니라 동시에 대규모의 침적을 경험하는 것으로 나타났다. 일주기별로 농도, 농도구배, 플럭스의 절대치를 분석한 결과 대규모 배출과 침적은 오후시간대에 왕성하게 진행되는 것으로 나타났다. 그러나 이들의 발생빈도에 대한 분석결과는 배출이 새벽 또는 저녁에 빈번하게 발생하는데 비해, 침적은 주로 오후시간대에 집중된다는 것을 확인하였다. 풍향대별로 발생빈도와 교환율을 비교한 바에 따르면, 대규모 침적을 유도하는 외부배출원이 동쪽지역에 위치해 있다는 것을 추정할 수 있었다. 특정 풍향에서 침적이 집중된 점을 감안하여, 침적이 집중된 방향의 자료군과 배출이 지배적으로 발견된 전체자료를 이용하여 조건별 환경인자의 변화동향을 배출/침적비로 환산하여 비교하였다. 그 결과 대부분의 오염인자들의 농도는 외부여건에 따라 규칙적인 변화양상을 보여주었다. 상관분석의 결과는 이들의 거동이 교환현상의 수직적인 방향-침적 또는 배출-의영향을 민감하게 반영하는 것으로 나타났다. 요인분석의 결과는 배출시에 기온과 같은 요인에 의해 유도되는 부분이 그리고 침적시에는 기온, 오존, 비메탄계 탄화수소와 같이 외부인자의 영향을 반영하는 요인들이 복합적으로 중요하게 작용할 수 있다는 점을 시사하였다. 난지도지역을 중심으로 한 수은의 자료를 추정한 결과 연간규모로 약 6kg의 수은이 배출되는 것으로 나타났다.

이 연구는 GPS를 이용한 서울-제천지역에 대한 대류층 천정 지연 분석에 관한 것이다. 다양한 기상조건하에서 정확도를 보장하는 GPS 측위를 위하여 대류층 천정 지연과 GPS 정밀도와의 연관성을 분석하였다. Bernese 4.0소프트웨어로 산출한 대류층 천정 지연값의 증가시 GPS 측위 오차도 증가하였다. 대류층에 의한 오차는 평균 20 cm 였으며, 보정 모델 사용시 모두 5cm 범위내로 줄일 수 있었으며, 보정 모델 간에는 차이가 거의 없었다. GPS 측위오차와 대류층 천정 지연의 상관관계를 밝힘으로써 전선의 이동상황을 모니터링할 수 있으며 이는 GPS 기준망의 확장으로 가능할 것이다.

We determined the precise three dimensional WGS84 Coordinates and the sea level height of Seoul Radio Astronomy Observatory (SRAO). In this study, we performed the simultaneous GPS observations at SRAO and Seoul GPS Reference Station(SGRS) of Korea Astronomy Observatory(KAO) for 3.5 hours from 17KST on October 27, 1999. We employed two different antennas, i.e., chokering antenna at SGRS of KAO and L1/L2 compact with groundplane antenna at SRAO. But we employed same type of receivers, i.e., Trimble 4000SSI at both observing places. The observed data were processed by GPSURVEY 2.30 software of Trimble with L1/L2 ION Free technique and broadcasting ephemeris of GPS Satellites because of very short baseline between SGRS of KAO and SRAO. We determined WGS84 latitude, longitude, height and the sea level height of SRAO with 37∘27′15.′6846N±0.′0004,126∘57′19.′0727E±0.′0002,204.89m±0.02m,181.38m±0.17m 37∘27′15.′6846N±0.′0004,126∘57′19.′0727E±0.′0002,204.89m±0.02m,181.38m±0.17m , respectively.
