Since dental prosthesis is made possible only when dental technicians give themselves to the study of knowledge and the acquisition of updated skills, continuing education is of great importance in that it makes up for the efforts of dental technicians. Accordingly, continuing education relates to a system designed to contribute to the enhancement of the talents of dental technicians and the dental health of the nation. Specialized knowledge and information may work as the best weapon to preserve their jbs. This is true of this modern society where no one can expecth to survive without acquiring knowledge and information constantly for work is getting more classified and more divirsifide. This paper is dedicated to take a look at the current condition of the continuing education of dental technicians and to come up with measure to make general evaluation and to improve continuing education. This research resorts to 609 questionnaires among 6433 copies save unfaithfully responded 34 copos with 6.431 dental technicians as the subjects enrolled in the Dental technician Association. The collected questionnaires consist of 365 dental technicians living in Seoul and of 244 ones, Which account for 11.8 percent of dental technicians enrolled in the association. Because dental technicians live more in local areas than Seoul, the generalization of this survey leaves something to be desired. I have come up with the following findings. 1. 6,431 dental technicians, or 36.3 percent of an total of 14,956 licensed dental technicians, were admitted as numbers of the Dental Tachnician Association as of October 31, 1999. In the '98 continuing education. 4,141 dental technicians among 4,711 dental technicians got relevant training, and in the '99 continuing education, 4,075 technicians, or 75.9 percent of 5,365 technicians got relevant training while 1,290 technicians or 24.2 percent, fail to get relevant training. 2. The survey has it that 38.1 percent of dental technicians are ignorant of the laws on continuing education, and that technicians staying in local communities(146 persons, or 61.6%) take more part in education than those living in the capital of Korea(159 persons, or 146%), and that the older they are, the more money they earn, the more carrer they have, the higher position they hold, the more part they take in education 3. According to the survey, those who have the experience of getting training more than three times account for 52 persons(16.8%) in Seoul and 47 persons(22.4%) in local districts(p<0.01). In terms of sanctions in relation to continuing education, 26 dental technicians(4.6%) say that they have ever gotten sanctions, and 533 dental technicians(95.4%) say that they haven't. And those who were absent from continuing education(72 technicians : 13.51%) didn't get any sanction. 4. In terms of the degree of understanding continuing education, local technicians(46.8% : 110 persons) have a higher understanding of continuing education than their countparts staying in Seoul(36.0% : 130). Continuing education is not the ultimate goal itself. It should be changed to motivate those who get education to be willing to take part in contunuing education, and to help dental technicians in a practical and specific way. And the branch societies should be developde to engage in more specialized and classified expert fields. Of course, the curriculum should be so selected that the conceptions of dental technicians may be reflected to the maximum extent, and the ultimate effores should be made to effect diversity in the ways of educational methods and to perfect the preparation of continuing education on the part of instructors. Regulations should be established in relation to continuing education with a veiew to enhancing the participation of continuing education and its effectiveness. The supervision of the Ministry of Health and Welfare is of great importance in this context. The regulation of continuing education is not administrative regulation, but the expression of national will to guarantee the medical service of the nation at highest level. Therefore, it is necessary that the Ministry of Health and Welfare should change their understanding of the needs for the continuing education of dental experts, and that the expertise of government employees in charge of continuing education should be expanded. It goes without saying that the government should suppory continuing education in a financial way so as to supply the person in charge of public welfare and control the quality of national medicine.

The hospitals that are owned by non-medical personnel result when non-medical personnel with resources conspire with newly graduated medical doctors who cannot afford the enormous amount of capital required at the beginning of the establishment of a medical institution. Such hospitals, though they may have met the external requirements as medical institutions, disrupt the medical market as it should be centered by medical personnels, In addition, such hospitals are causing a huge social problem as it is illegally receiving and reducing various benefits such as medical care benefits and subsidies from the government, resulting in a significant financial leak in the national health insurance. The illegality of the opening of a non-medical personnel hospital is so high that it nullifies the contractual arrangement for the establishment, imposes criminal penalties on all persons involved in the establishment under the Korean Medical Law, and imposes administrative sanctions on medical personnel. In case the hospital was aware of the illegality of its opening, but had applied to receive medical care benefits from the National Health Insurance Act and the Medical Care Act, such actions will result in the return of the benefits under the National Health Insurance Act and the Medical Care Assistance Act, subject to the penalty for the crime of fraud, and aggravated punishment for specific economic crimes based on the amount of gain, as well as civil liability for torts. In this study, we will examine the current status of the regulations on the non-medical personnel hospital and present the basis for future legislative directions by looking at the legal regulations and the attitude of the precedents.

Osteosarcoma is a primary malignant tumor arising most often in the long bone, but rare in jaw bone. Especially osteogenic sarcoma of the mandible is a rare tumor, comprising less than 0.5% of all head and neck tumors. Osteosarcoma occurs chiefly in young persons, and presenting very survival rates. Histopathologically this tumor can be classified three types, osteoblastic, fibroblastic, chondroblastic and classified from low grade to high grade by anaplasia or mitosis of the tumor cells. Sometimes, the exact diagnosis of osteosarcoma is difficult especially in low grade osteosarcoma, even if clinical or radiographical findings suggest to osteosarcoma. So suspcious to malignant bone tumor in clinical or radiological findings, biopsy should be taked from deep portion and multiple area, and sharing the patient history and radiographs with pathologist will assist in the development of the diagnosis. We report a case of low grade osteosarcoma on the mandible initially difficulty in accurate diagnosis. The patient visited our hospital for routine dental treatment but radiographic findings displayed ill-defined radiolucency with osteoid formation on the mandible. Final diagnosis was difficulty in initial biopsy but subsequent biopsy taked from deep portion presented infiltrative growth and mitosis of the tumor cell in some area with small osteoid bone formation, so we could reach final diagnosis as low grade sarcoma. We treated this patient with bloc resection of the mandible and immediate reconstruction with iliac corticocancellous block.

The purpose of this study is to identify the satisfaction with medical services of the disabled elderly who have the highest need for medical services. For this purpose, the effect of health characteristics and medical service characteristics of the disabled elderly on medical service satisfaction was verified. The subjects of analysis were 3,323 persons with disabilities aged 65 or older who were taken from the national survey of people with disabilities in 2017. For statistical analysis, descriptive analysis, correlation analysis, and regression analysis were performed using the SPSS 26.0 program. The results of the study showed as follows. As a result of the regression analysis, gender (β= -.045, p<.05) and residence status (β= -.048, p<.05) among the demographic characteristics as control variables had a statistically significant effect on the level of medical service satisfaction. Among the health characteristics, IADL (β=-.044, p<.05) had a statistically significant effect on medical service satisfaction level. In the case of medical service characteristics, satisfaction with medical facilities and equipment (β = .290, p< .001), medical staff's level of understanding of disability (β = .404, p< .001), health-related service use (β = .182, p<.05) had a statistically significant effect on the level of medical service satisfaction. Based on the results, practical alternatives to ensure health equity in the community medical system were suggested in the discussion to enhance the health management and self-determination capabilities of the disabled elderly.

A small-scale epidemiological survey was undertaken during 1997-1998 on the residents along the Osib-chon (Stream), Samchok-shi (City), Kangwon-do (Province), to evaluate the status of Metagonimus yokogawai infection. A total of 165 fecal samples was collected and examined by cellophane thick smear and formalin-ether sedimentation techniques. The egg Positive rate of M. yokogawai was 29.7%, showing a remarkable difference between males (46.6%) and females (16.3%). To obtain the adult flukes of M. yokogawai, 11 egg positive persons were treated with praziquantel and purged with magnesium sulfate. A total of 242,119 adult flukes (average 22,010 per person, 367 119,650 in range) was collected from diarrheic stools, all of which were identified as M. yokogawai. The results show that M. yokogawai is still highly endemic in this area.

Objective : To investigate the relationship between medical expenses and the burden of families caring for the elderly in the last 6 months of life, and to evaluate the factors relating to the burden of family caregivers. Methods : The families of 301 persons older than 65 years, who died between 1 July and 31 December 2001, and were registered in Resident-based- Health Insurance Programs in Seoul, were interviewed. The medical expenses and length of stay among the elderly were collected from Korean Health Insurance Corporations. Results : 31 percents of the elderly had no medical expenses in the last 6 months of life. On average, the objective burden (4.92) was higher than the subjective burden (3.35). Families caring for male elderly had a higher burden. With increasing age af death, the objective burden was significantly increased. The burden on a family seemed to be influenced more by the family income than the property of the elderly. With increasing total health care costs, the objective burden on the family caregivers was significantly increased, but with increasing medical expenses, the subjective burden was significantly decreased. Conclusion : An association between healthcare utilization and burden on families was observed. The reason for the decreasing subjective burden when medical expenses were decreased was unclear. Further research will be needed.

This study aims to identify the awareness and performance level of hospital infection control in medical technicians working in small and medium-sized hospitals. The experiment was conducted in 235 medical technicians (medical laboratory technologist, radiological technologist, and physical therapist), and for statistical processing, SPSS Ver.23.0 was used to conduct mean and standard deviation, analysis of variance, and regression analysis. As a result, it was found that the major cause of improper infection control was lack of experts ($3.17{\pm}1.18$) and performance level was statistically significantly lower than awareness of infection control. "I took no measures after infection accident" was responded the highest at 40.0%(94 persons), and in "I reported to the head of department after disinfection, examination, and/or vaccination," the standardized regression coefficient ${\beta}$ was -0.265, p=0.025, which suggested that there was a significant negative (-) impact. Infection control level showed a significant positive correlation with training and infection control instructions. Therefore, it was found that medical technicians in small and medium-sized hospitals required high skilled manpower in infection control, training, infection control instructions, etc. Through this study, more effective infection control is considered to be possible.

Background: Colorectal cancer is a main leading cause of cancer death in western countries. Although many studies have been conducted on incidence trends all over the world in recent years, information regarding changes in incidence of colorectal cancer in Iran is insufficient. The present study of colorectal cancer in the west of Iran during recent years was therefore performed. Materials and Methods: The registered data for colorectal cancer cases in National Cancer Registry System were extracted from the Ministry of Health and Medical Education, Center for Disease Control and Management. The codes from 18-21 among cancers were selected for colon and rectum cancers. Incidence rates were standardized directly using WHO population. The significance of incidence rate trends during 2000-2005 was tested through Poisson regression. Results: 762 cases of colorectal cancer were observed during 6 years in this region, with a gender ratio of men to women of 1.2. It increased from 65 cases in 2000 to 213 cases in 2005 or from 1.5 per100,000 per persons per year to 4.8. Significant increasing trends were evident in Kermanshah and Hamadan provinces; however, change did not reach significance in Ilam and Kurdistan provinces. Conclusions: Colorectal cancer has an increasing trend in the west of Iran. Although it seems that the increasing rate of colorectal cancer is due to increasing of cancer risk factors, some proportion may be related to the improvement of surveillance systems in Iran.
