Purpose: This study was conducted to improve the working conditions of dental technicians, through survey for working conditions related to perform one's duty, the extent of personal exposure to substances hazardous and complaint rate and factor of job stress and subjective symptom on musculoskeletal disorders. Methods: Using four types of structured questionnaires: social and demographic factor; the actual conditions of working space; working conditions; and characteristics of dental technicians, respondents filled in the questionnaires and the results were analyzed statistically. Results: The evaluation of comfort in working place found that satisfaction level on indoor noise was the lowest with 2.6 on a five-point scale and privacy space followed 2.8 point. In reasons for dissatisfaction with job, over workload ranked the highest by 25.4% and role overload had the highest by 39.5% in job stress factors. Based on the results, we could draw conclusion that dental technicians were unsatisfied with role overload and heavy workload a day. In reasons for musculoskeletal symptom prevalence, long-patient work was the highest by 24.1%. It was thought to cause dental technicians need deep procession and long-patient work due to the nature of their job. Conclusion: In conclusion, noise reduction and privacy space are required to improve job efficiency of dental technicians. In addition; we need to think of ways to increase the job satisfaction with adequate rest while deep procession and long-patient working.

총 388건의 시료를 분석한 결과, 닭 143건 중 총 12건의 플루오르퀴놀론계 항생제가 검출되었으며 다른 식품군에서는 모두 불검출 되었다. 항생제 별로 보면 엔로플록사신이 12건으로 가장 많았고 시프로플록사신이 5건, 노르플록사신이 1건 순이었다. 검출농도는 엔로플록사신이 0.01-0.73 mg/kg, 시프로플록사신이 0.01-0.03 mg/kg 및 노르플록사신이 0.12 mg/kg이었다. Residual fluoroquinolone levels in animal foods retailed in Korea were monitored according to the method outlined in Korea Food Code using HPLC-FLD and HPLC-ESI-MS/MS for confirmation. The optimum ion transitions were 360→316, 342 m/z for enrofloxacin, 332→314, 288 m/z for ciprofloxacin, 320→301, 230 m/z for norfloxacin, 334→315, 290 m/z for pefloxacin, 362→318, 261, 334 m/z for ofloxacin, and 262→201, 126 m/z for flumequin. Enrofloxacin, ciprofloxacin and norfloxacin residues were found in 12 out of 388 samples. These antibiotics were only found in chicken samples, while no residues were found in beef, pork, milk and egg samples. Using this monitoring method, detection rates of 3.1, 1.3, and 0.3% were obtained for enrofloxacin, ciprofloxacin and norfloxacin, respectively. The levels of enrofloxacin, ciprofloxacin and norfloxacin detected in food samples ranged from 0.01 to 0.73 mg/kg in 12 samples, 0.01-0.03 mg/kg in 5 samples, and 0.12 mg/kg in only a sample, respectively.

알(卵)류 및 축·수산물 321건에 대하여 엔로플록사신, 시프로플록사신, 노르플록사신, 아목시실린, 암피실린, 옥소린산 및 옥시테트라싸이클린, 테트라싸이클린, 클로르테트라싸이클린 및 독시싸이클린에 대한 모니터링을 실시한 결과 총 300건(93.5%)은 조사대상 동물용의약품이 불검출되었으며 검출된 21건(6.5%)의 시료 대부분은 현재 식품공전의 잔류허용기준 이하로 안전한 것으로 나타났다. This study was conducted to monitor residues of 10 veterinary drugs in food products. Various veterinary drugs were examined including enrofloxacin, ciprofloxacin, norfloxacin, oxolinic acid, amoxicillin, ampicillin, oxytetracycline, tetracycline, chlortetracycline, and doxycycline in beef, pork, egg, chicken, eel, flatfish, and rockfish obtained from 6 different regions (Seoul, Incheon, Daejeon, Gwangju, Daegu, Busan). Residues were detected in 21 (6.5%) samples out of 321 samples. In particular, 2 (1.0%) livestock samples had detected residues among 203 products, and 19 (16.1%) aquaculture samples had residues detected among 118 products. The most frequently detected drug residues in aquaculture products were oxytetracycline and amoxicillin, but the levels were mostly below the MRL (Maximum Residue Limit). In only one flatfish sample, amoxicillin was found at a level higher than the MRL (0.05 mg/kg). In livestock products, residues of most veterinary drugs were not detected. But enrofloxacin was detected in 2 chicken (Korean name: Ogolgae) samples at a higher level than the MRL (0.1 mg/kg as the sum of ciprofloxacin).

본 연구에서는 인천과 춘천지역에서 각각 초등학교 4개 학교와 중학교 4개 학교 등 총 16개 학교를 선정하여 주식, 부식 및 후식 등 1334건의 메뉴에서 당 함량 및 당 섭취실태를 조사하였다. 학교급식을 통한 섭취량은 전체 평균 410.9±85.8 g/인이었다. 전체 급식메뉴의 평균 당 함량은 1.93±3.35 g/100 g이었으며, 급식 메뉴를 주식, 부식 및 후식으로 나누었을 때 평균 당 함량은 후식류(7.21±6.32 g/100 g)>부식류(1.69±2.44 g/100 g)>주식류(0.32±0.77 g/100 g) 순으로 나타났다. 평균 당 함량은 주식류에서 면류>죽류>일품식밥류 순으로 높았고, 부식류에서는 소스류>튀김류>절임류>무침ㆍ나물류>볶음류 등의 순으로 높게 나타났다. 당 섭취량 또한 후식류(4.63±5.11 g)>부식류(0.64±1.01 g)>주식류(0.55±1.48 g) 순으로 높게 나타났다. 급식 중 당 섭취량은 주식류에서는 일품식 밥류의 당 섭취량이 높았고, 부식류에서는 튀김류>볶음류>소스류>조림류의 순으로 당 섭취량이 높았다. 후식류에서는 음료와 유제품류의 당 함량과 섭취량이 다른 음식군에 비해 높았다. 급식일별로 점심 급식 한 끼에 섭취하는 평균 당 섭취량은 초등학생 4.03±3.67 g/인, 중학생 6.97±6.59 g/인이었으며, 전체 평균 당섭취량은 5.50±5.53 g/인으로 한국인 총당류 섭취기준치와 비교했을 때 높지 않은 수준으로 나타났다. 그러나 Kang과 Yoon(8)의 연구결과 초등학생의 91.5% 가 주로 하루에 1-2회 간식을 섭취하며, 선호하는 간식이 과자, 과일 또는 과일주스, 빵 또는 케이크류 순으로 나타나 학생들의 간식을 통한 당 섭취는 높을 것으로 사료된다. 따라서 학교급식을 통해 단 맛에 길들여지지 않으며 올바른 식습관을 형성하도록 영양교육할 필요가 있다. 또한 학교별로 조리사와 조리법에 따른 당 함량에 차이를 보임에 따라 당 함량을 줄일 수 있는 조리법의 개발, 통일된 조리법의 보급 및 조리사의 교육과 급식 식단 구성 시 당 섭취량이 높았던 음식군을 중복하지 않고, 후식류로 과일류를 제공하는 등 메뉴의 조합에 주의함으로써 학생들의 당 섭취량을 줄일 수 있을 것으로 사료된다. The purpose of this study was to analyze the content and consumption of total sugar from school lunches at Incheon and Chuncheon. The samples were collected from eight elementary schools and eight middle schools in Incheon and Chuncheon for 15 days. The analysis of total sugar content was performed for 1334 main dishes, side dishes, and desserts, which were supplied by elementary and middle school foodservices. Total sugar content was extracted from various types of food with 50% ethanol after defatting. We simultaneously analyzed sugars such as fructose, glucose, sucrose, maltose, and lactose by a high performance liquid chromatography with refractive index detector. The average lunch intake for elementary school and middle school students was 372.6±72.2 g and 449.2±81.1 g, respectively. The total sugar content in desserts was 7.21±6.32 g/100 g, 1.69±2.44 g/100 g in side dishes, and 0.32±0.77 g/100 g in main dishes. Among side dishes, fried foods, stir-fried foods, and sauces contained the highest amounts of total sugar. The total sugar intake was 4.63±5.11 g in desserts, 0.64±1.01 g in side dishes, and 0.55±1.48 g in main dishes. Main and side dishes with a high total sugar intake included cooked rice with seasoning, fried foods, stir-fried foods, and preserved foods. The average total sugar intake per meal for elementary school, middle school, and all students was 4.03±3.67 g, 6.97±6.59 g, and 5.50±5.53 g, respectively. We have provided useful information to decrease the intake of total sugar in school lunches. It is recommended that total sugar intake be continuously monitored.
