This study was performed to investigate the task status and performance improvement plan of dental hygienists of Health Centers and Subcenters. The Data collected by self-administered Questionnaire survey of 203 dental hygienists of Health Centers and Subcenters located in Gyeongsangbuk-do were analyzed. The major results are as follows: For the degree of satisfaction in tasks, 73.9% of dental hygienists of Health Centers and Subcenters felt proud, 52.2% felt overwork, 32.0% hoped transferring to other worksite and the major reason of transferring was lack of promotion opportunity in officials of dental hygiene department. Dental hygienists received job education in addition continuous job education in last 3 years were 47.3%, 19.2% of dental hygienists performed the special dental health program for residents in last 3years. Almost half(53.7%) of dental hygienists replied that dental hygienists who were not engaged in dental health tasks should be engaged in dental health tasks. The major dental hygienic tasks performed by dental hygienic officials were support for dental treatment(41.6%). Dental hygienic officials answered that dental health tasks, school dental health program, vertical dental health program should be conducted as important tasks in order. And they replied that the most serious problem of dental hygienic tasks was not conducting dental health affairs due to 'lack of dental doctor'(40.9%), 'lack of concern for dental health tasks'(26.4%), and 'lack of budget and personnels for dental tasks'(19.0%), and the most important thing to improve dental hygienic tasks was 'posting dental hygienists in ministry of health and welfare(MOHW) and province', 'securing of budget and personnels for dental health tasks'.

질환성과 관련된 세균의 분포 및 유전자형을 탐색하고자 구강농양 및 골수염의 급성감염 혼자와 진료실 및 실험실의 정상인을 대상으로 시료를 채취하여 포도상구균을 분리 및 동정을 시행하고, 특성을 규명하였으며, plasmid 및 염색유전자를 분리하여 제한효소를 처리후 전기영동을 실시하고 분리된 plasmid로 탐색자를 제작하여 dot blot을 시행하였다. 대부분의 급성환자에서 분리된 포도상구균을 S. lugdunensis와 S. aureus이었으나, 진료실 및 실험실에서는 coagulase 음성 staphylococci가 분리되었다. 급성환자에서 분리된 포도상구균은 ampicillin과 penicillin에 내성을 보였다. 분리된 S. lugdunensis균주중 네 균주는 ${\delta}$형의 용혈소를 생산하였다. Plasmid를 분리한 결과 S. lugdunensis균주중 세 균주는 약 6.5 kilobases이었으나 S. aureus는 약 4.3 kilobases 정도 크기의 band를 보였다. S. lugdunensis에서 분리된 plasmid로 제작한 탐색자로 dot blot를 시행한 결과 치과 영역에서 분리한 plasmid를 갖는 균주는 양성반응을 보였다. 염색체유전자의 유전자형을 분석한 결과 ${\delta}$형의 용혈소를 생산한 네 균주의 S. lugdunensis는 유사한 유전자형을 보였다. 이러한 연구결과 질환의 진행에 S. lugdunensis가 중요한 역할을 하는 것으로 생각되고, 치과영역에 존재하는 plasmid는 공통적인 유전자 서열을 갖는 것으로 추정된다.

Materials that can be use in CAD/CAM are composite, ceramic, hybrid and metal. Among the available materials, monolithic ceramic technique which is the manufacturing technique using one type of the materials is mainly used in a dental office. It is the technique where final tooth-shaped prostheses are made from the material block and used after polishing or applying heat and that does not require traditional ceramic build-up process. Although shot of esthetic quality, because manufactured within 1 hour the monolithic ceramic technique has advantages such as that treatment can be completed in one day and in one time visit, that stability of the material is high because there are low possibility of distort by not melting and phase transformation, and that it can be easily worked in the office with computer assisted devices. We classified the materials that can be used in this technique based on their generations from clinical stand point.

Not to recreate the final prosthesis is the shortest way to get a successful outcome. In the case of an aesthetic prosthesis, it is important not only the condition of the oral cavity but also the whole harmony in the face such as the interpupillary line and the smile line. But the dental technician creates the prosthesis only based on the oral model. So if you want to prevent the failure of the prosthesis due to discordance with the face, it is a good idea to use patient's facial photography and provisional restorations to reproduce facial features, shapes and aesthetics before switching to a final prosthesis. To prevent the failure of the final prosthesis, it is important to communicate among the patient, the technician and the doctor according to the model diagnosis, facial and oral photos. Then all the technicians will get satisfactory results. In addition, the technician have to understand the form of natural teeth, to analyze and reproduce colors, and to understand materials in order to produce a successful aesthetic prosthesis. From now on, I will explain two parts. At first, the communication in the dental office for the successful production of aesthetic prosthesis through the clinical case. And the second, my opinion for the successful aesthetic prosthesis.

Statement of problem: There are two methods of color choice for the esthetic restoration. One is visual shade matching which draws a comparison between shade guide and teeth in dentist's own eye and the other is using a digital shade analysis system recently introduced. Although the visual shade matching has a lot of problems, decision of color by this visual shade matching and the ways of expression for the decided color are still applicable to clinical dentistry. Purpose: This study is designed to investigate shade guides used in the dental clinics and laboratories have the same value using ShadeEye-$NCC^{(R)}$ dental chroma meter (Shofu Inc., Kyoto, Japan) using shade guide are evaluated. Material and methods: At the first experiment, eight Vita Lumin Vacuum shade guides (Vident Inc., California, USA) were collected from the dental clinics. A1 and B1 shade tabs are chosen and the colors are analyzed five times each in both tooth and porcelain modes by digital shade analysis system, ShadeEye-$NCC^{(R)}$. In the second experiment, twelve Vita shade guides using practically in the dental clinics and laboratories were collected and also A1 and B1 shade tabs are chosen and the colors of A1 and B1 are analyzed one time each in both tooth and porcelain modes by ShadeEye-$NCC^{(R)}$. Results and conclusion: There were significant differences among eight shade guides in terms of shade (chroma), value and hue in both of A1 and B1 (P<.05). Shade guides using in present both dental clinics and laboratories did not show significant differences, except A1 in the porcelain mode, it showed significant differences (P<.05) in the shade even though the shade tab has the same name.

Dentally disabled person means one who have difficulty in cooperating voluntarily with a dentist for routine dental care. Seoul National University Dental Hospital (SNUDH) Dental Clinic for Disabled has worked for them under outpatient anesthesia concept. The aim of this study was to determine the anesthetic characteristics of the patients attending for dental treatment at SNUDH Dental Clinic for Disabled in order to establish better future treatment plans. The data were drawn from the patients who visited SNUDH Dental Clinic for Disabled from January 1999 to October 2002. Total 93 dental treatments for 83 patients were enrolled in this study. Most patients had mental retardation and the conservative treatments were carried out under general anesthesia. Thiopental and vecuronium were mostly used for induction agent and neuromuscular blocker, respectively. Enflurane, with oxygen and nitrous oxide, was mostly used to maintain the anesthesia. Mean total anesthetic time was $164.4{\pm}57.2$ minutes and mean duration at the post-anesthetic care unit was $106.2{\pm}50.5$ min. Serious postoperative complications were not observed. These results showed our successful anesthetic outcomes without any severe side effect or complication and the needs of more outpatient centers for dental care for disabled.

How does analytical psychology help understand patients at general psychiatric clinics? It's necessary to think about how knowledge of analytical psychology can help young psychiatrists who are in training. Patients who come to us bring symptoms(problems). Symptoms can be compared to tickets to a movie theater. Symptoms accompanied by complaints of pain are not only pathological phenomena to be eliminated, but an important pathway to access the patients' inner problems. In terms of seeing the whole, the point of view in analytical psychology is to see the unconscious as well as the consciousness, even the elements the patients do not speak or know of. When determining indications and contra-indications during the initial process of treating a patient, it is more important to acknowledge the therapist's capabilities and limitations than the patient's condition or limitations The approach to complaints of the same symptoms may differ depending on whether the patient is in the first half or the second half of one's life. Analytical psychology is empirical psychology that experiences and it adheres to a phenomenological position that recognizes the phenomenon as true in itself, not logically right or wrong. The analytical psychological view of understanding mental phenomena asks the causal perspective of why the symptoms occurred. At the same time, the therapist, along with the patient, must seek answers to the question of why now and for what purpose. A therapist is a person who experiences the patient's personal development process together. In analytical psychotherapy, the therapist's attitude is more emphasized than the treatment method or technique; it is regarded as of the utmost importance. In this regard, analytical psychology is a practical and useful therapeutic tool, and is a field of study that can be widely used in actual psychiatric clinics. In addition to understanding the patient, it is also the most important discipline for the therapists, especially for the education and growth of those who want to become a treatment tool themselves.

The 4th year medical students were randomly divided and designated as group HF and LF, representing high and low fidelity simulations respectfully. Both groups performed OSCE on 2 topics(adult intubation and IV cannulation) with each composed of the same scenario. Each scenario was developed by a faculty in charge of clinical skill education with supervision from 2 other faculty members. High fidelity simulations were designed as in-situ simulations in real OR. Low fidelity simulations had the same scenarios but the environment was simulated only with a simple task trainer in the classroom. All students participated in series of survey using a Likert scale before and after the simulations. The provided data was anlayzed with paired T-test and Mann-Whiteney test(p<0.05). The post simulations self evaluation score for group HF was lower than pre-simulation self confidence score for both topics of adult intubation and IV cannulation where as for group LF, it was lower only for adult intubation(p<0.05). In group HF, the needs for clinical training on both topics increased after the simulation. In group LF, there was no significant change of needs for clinical training between pre and post simulation survey. This suggest that fidelity may be a helpful factor to improve the motivation of the students and further study on economical aspect should be addressed.

At the time of medical treatment and surgical operation, halogen lamp and plasma lamp were mainly used as luminous source for lighting. These two luminous sources have drawbacks that the life of lamps are not long, various problems are brought about due to excessive heat generation and its volume is very big because of cooling device. Accordingly, in this research a ring light was developed so that a partial shadowless shooting for the patient's affected area at the medical treatment room and surgical operation room using high luminance LED for which attention is being paid as new lighting parts for medical purpose. LED which was applied to the development used high luminance three color LED for full color for which various color materialization and the adjustment of radiation intensity are possible and we can get white light in order to emphasize the delicate expression for generic tone of shooting object, strong highlight, simple shadow and three dimensional effect at the time of close-up shadowless shooting of the affected area.
