The environmental conditions and the altitude of ground water collecting areas were recorded, and the bacteriological and physico-chemical examinations of rural ground water were undertaken, from April, to April, 20 in 1986. Twenty seven ground water samples were brought with ice-box within six hours to our laboratory. They were sampled from six wells, eight pumps, and three automatic pumps located in kunsung Myon, Kumryung Gun, Kyungpook province. Almost all of the samples were found to be contaminated by coliform bacteria except one, Hagang 1 dong (See No. 27 in figure 1). Otherwise, E. coli was isolated from 24 samples ex-cept three; - Ryimchon dong (No. 10), Yangkag 1 dong (No. 26) and Hagang i dong (No. 26). In general, bacteria count, nine samples (No. 6,7,9,13, 17,21,22,23, and 24) werw unsuitable to standard for drinking water. In 23 kinds of physico-chemical factors investigated, hy drogen ion, alkalinity, total hardness, flouride and all metals were within standard values for drinking water, but turbidity (for No. 10, 11, and 16) were higher than standards, chlorine (for No. 7,12,13,22, and 23) ammonia nitrogen (for No. 7,13,16, 22, and 23) and nitrate nitrogen (for No. 22 and 23), also. The lower altitude of sampling sites were the higher bac-teriological contamination, water temperature, turbidity, am-monia nitrogen, phosphate and mercury contents. In comparision with the water supplying style and bacter-iological and physico-chemical contents, the wells were more remarkablely contaminated than pump or automatic pumps. Correlation of bacteriological contamination with chlor-ine, ammonia nitrogen and nitrate nitrogen concentrations were significantly positive respectively. And it was highly nega-tive correlation with the distance of contamination sources; toilet or cattle shed. The shorter distance from farms were the higher in arsenic and mercury contents.

It is necessary to acquire a fundamental impression in distal extention partial denture so as to make the mutual relation among the ridge under denture base, abutment teeth and frameworks closer, correcter, and well functioning. It can be obtained by impressing the Surface of a functionally_made residual ridge. It is possible to extend the length of a denture base as long so possible and to do a border molding well enough so long as it does not interfere with fuctional operation of Various organs and tissues in order Cavity. The conclusion is that these are for the support of denture base of partial denture and tissues.

This study was conducted to determine the residual amount of veterinary drugs such as meloxicam, flunixin, and tulathromycin in animal products (beef, pork, horsemeat, and milk). Veterinary drugs have been widely used in the rearing of livestock to prevent and treat diseases. A total of 152 samples were purchased from markets located in major Korean cities (Seoul, Busan, Incheon, Daegu, Daejeon, Gwangju, Ulsan and Jeju), including Jeju. Veterinary drugs were analyzed by liquid chromatography-tandem mass spectrometry according to the Korean Food Standards Code. The resulting data, which are located within 70-120% of recovery range and less than 20% of relative standard deviations, are in compliance with the criteria of CODEX. A total of five veterinary drugs were detected in 152 samples, giving a detection rate of approximately 3.3%; and no food source violated the guideline values. Our result indicated that most of the veterinary drug residues in animal products were below the maximum residue limits specified in Korea.

암, 당뇨, 심장질환 등의 성인병 예방에 좋은 효과를 제공하기 때문에 선진국에서는 통곡의 섭취를 권장하고 있으나, 곡물이 겨층을 포함하고 있어 식미가 거친 단점이 있다. 초록통쌀은 호숙기에 수확하여 조직이 경화되지 않고 각종 미네랄, 비타민, 식이섬유 등 영양성분이 풍부한 것으로 알려져 있다. 본 연구는 고령자의 영양보충 및 식감 개선을 위한 초록통쌀 현미의 영양성분 및 효소처리에 따른 이화학적 특성변화를 분석하였다. 국내 다 소비품종인 삼광, 조평, 추청 3종의 초록통쌀의 영양성분을 비교 분석하였으며, 4종의 효소 처리(0.1 ~ 3%)에 따른 신속호화점도계, 전자현미경, 아밀로펙틴 함량 등의 이화학적 특성 변화를 측정하였다. 삼광, 조평, 추청의 주요 영양성분의 함량은 100g 당 비타민 B1이 144, 100, 105ug, 식이섬유가 21, 13, 12g, 폴리페놀이 63, 52, 56mg으로 삼광이 가장 높은 것으로 확인되었으며, 비타민 B2, 나이아신, 칼륨, 인, 마그네슘, 총 엽록소도 높은 것으로 나타났다. 효소농도가 증가함에 따라 경도가 감소하였으나, 0.3% 이상에서는 유의적 차이가 없는 것으로 나타났다. 대조군 및 각 효소처리에 따른 식미적 합성을 나타내는 신속호화점도계 peak 값은 760, 724, 708, 754, 761 cP이었고, 시간변화에 따른 품질특성을 나타내는 Breakdown 값은 157, 166, 151, 100, 99 cP로 두 항목 모두 셀룰로오스계열 효소 D 처리 시 식미가 가장 우수한 것으로 확인되었다. 전자현미경 확인결과 효소처리에 따른 물성변화로 입자간 간극이 커짐을 확인하였다. 전분의 분자량 분포특성인 아밀로펙틴 측쇄사슬 길이는 모든 처리군 평균값이 15.71~15.99 DP로 효소처리에 따른 아밀로펙틴 함량 변화는 없는 것으로 나타났다. 이러한 결과는 셀룰로오스 계열 효소처리를 통하여 물성조절이 가능하고 식미도 우수한 것으로 나타나, 초록통쌀은 저작능력이 약한 고령자가 쉽게 섭취할 수 있고, 영양개선을 위해 활용할 수 있음을 제시하고 있다.

Generally, Aker's clasp is used distal extension Removable partial dentures. But it is producing Lateral force and stress on the abutment tooth. is non-esthetic and clasp tip(of Asker's clasp) tends to dislocation award and undercut area of tooth due to a vertical disloding force. Therefore of residual ridge and tipping of abutment tooth is not special case, This results that bar type clasp, wrought wire clasp, reverse action clasp, backaction clasp are appropriate Retainers tha less stressed on aboutment tooth.

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.
