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.

This study was designed to examine the fit between an individual and his similar personalities were defined as person-person fit (P-P fit), and one s cur-leader's personality and one's current job features. The individual and leader's rent job features and his ideal job features were defined as person-job fit (P-J fit). This study also examined the difference of P-P fit and P-J fit on person's employee engagement, self-esteem, job satisfaction. The analysis of variance (ANOVA) was used to examine the difference between P-P fit group. And t-test was used to examine the difference between P-J fit group. This result implies that when one's personality was respected, one adjusts well to his work environment and as one gets ideal work, he engage more to improve his outcome. Finally, some suggestions for the increase of the level of job satisfaction of den-tal technicians are introduced and discussed.

This study was conducted to analyze the dental care utilization patterns and Utilization Patterns by the unauthorized illegally in community residents. The questionnaire survey was carried out for 1,344 peoples who visited private dental clinics during from May, 1, 1996 to July, 31, 1996. 30 private dental offices were randomly selected and 60 examiner were trained for questionnaire. The questionnaire asked the dental patient to report general characteristics, experience of kinds of dental prosthetics and dental facilities. Subjects were also asked about the preference reason of using their own dental prosthetics. The summarized results are as follows: The rate of person who had experienced dental prosthesis during ten-year period was 63.0%, and it was higher in older age, in lower education level, higher income. The rate of person who had treated dental prosthetics by the unauthorized illegally was 12.3%, and the reason for it was cheap-price fee(59.5%). Of the persons who had treated dental prosthetics by the unauthorized illegally, 34.6% were not satisfied and 76.3% had done out of use, while each was 24.3%. 47.4% at dental clinics. In consideration of above findings, we may conclude that oral health community program to prevent oral diseases should be intensified, oral health education to raise oral health knowledge should be performed periodically and the control of unlicensed activities should be enforced. ​

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.

It is natural that we should design partial denture considering major connector, minor connector, occlusal rest, base and artificial teeth, etc. in designing partial denture and some-thing that we ought to consider all the more is that all forces is case which operate with fulcrum line and Rational line in the center have to distinguish vertical forces, in the other words, forces which face tissue from forces which is about to escape from tissue, and hori-zontal forces that operates in laery direction from operation on the tilting. We should design forces which operate on such partial denture and in direction which reduces this possible as we can.

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.

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.
