Background:
Many countries need help with the problem of an unbalanced distribution of physicians and hospitals. Moreover, various policies and strategies have been proposed to solve this problem. This study aimed to examine the determinants of the unbalanced distribution of physicians.
Methods:
From the 2020 Korean Physician Survey data, 4,181 physicians practicing in Korea were limited to the subjects of the study. We analyzed the factors influencing physicians’ choice of practice location and their willingness to change their practice location from an urban to a rural area.
Results:
The region of physicians’ hometown, medical school, and residency training hospitals determined their choice of practice location. The type of affiliated healthcare organization and the location of physicians’ hometown, medical school, and residency training hospitals affected their willingness to change their practice location from an urban to a rural area. Furthermore, the concordance rate of the regions of physicians’ hometown, medical school, and residency training hospitals with the region of their practice location was 24.9%.
Conclusion
In South Korea, policies for doctors have been designed without considering why they are reluctant to work in rural hospitals. To have a balanced distribution of physicians and hospitals, it is necessary to accurately analyze the status of medical resources based on regions and identify the current and future medical demand. The social situation, such as future demographic change and regional extinction, must also be fully considered. Furthermore, policies should be implemented that encourage physicians to work in rural hospitals.

PURPOSE: This study was conducted to compare in vivo biofilm formation on titanium surface and zirconia surface. MATERIALS AND METHODS: For biofilm formation on titanium and zirconia in oral cavity, after producing oral appliances using acrylic resin and orthodontic wire tailored to 9 subjects, we made titanium and zirconia specimens (6 mm x 6 mm x 2 mm), fixed them on oral appliances and maintained them in oral cavity of test subjects for 24 and 72 hours. Test subjects who have equipped two pairs of specimens maintained oral hygiene not by using toothpaste but only by tooth brushing. After 24 and 72 hours, we removed and observed specimens through scanning electron microscopy (SEM). RESULTS: Biofilm formation showed large deviation depending on individuals. For formation comparison between titanium and zirconia for 24 hours, zirconia showed less biofilm formation than titanium. Biofilm formation showed large deviation depending on individuals. As for formation comparison between zirconia and titanium, the degree of biofilm formation in zirconia was less than it was in titanium after a lapse of 24 hours. The result of biofilm formation in 72 hours trial show that zirconia has an inclination to formate less biofilm than it was in titanium. CONCLUSION: Based on the above results, we can conclude that early biofilm formation in oral cavity was influenced by difference of abutment materials.

Trichilemmal horn(trichilemmal keratosis) is a rare keratinizing tumor that resembles a cutaneous horn. Histologically, it is characterized by an abrupt maturation of keratinocytes into lamellar keratin without the formation of a granular layer. We describe a case of a trichilemmal horn on the right cheek of a 78-year-old woman.

Journal of the Korean Medical Association 2022;65(1):79-84
Background:
A bill for the mandatory installation of closed-circuit television (CCTV) in operating rooms, still likely in breach of the constitution, was approved. When a bill infringing on individuals’ fundamental rights is drafted, alternative means of minimizing the infringement of the offender’s rights should be considered ahead of the draft. To this end, alternatives on the bill identified through the consciousness of the offender would be most realistic and much more effective. Thus, this study examined doctors’ consciousness on the mandatory installation of CCTV in operating rooms, the appropriateness of punishment for members who commit immoral and unethical behaviors, and doctors’ alternative ideas to CCTV installation in operating rooms.
Methods:
The online survey was conducted for a week from July 9, 2021, to July 16, 2021, by the Korean Medical Association Doctors News, and 2,345 doctor members responded to the investigation.
Results:
According to the survey, the following alternatives to CCTV installation in operating rooms were proposed: strengthening punishment for performing ghost surgery (38.3%), placing cameras at the entrance of the operating room (21.8%), mandatory written consent (pledge) (13.7%) to prevent ghost surgery for medical staff participating in the surgery, promoting self-purification (whistle-blowing) (11.5%), and a biometrics function for entering operating rooms (8.8%).
Conclusion
The revised medical law delegated legislative devices to subordinate statutes for minimizing infringement. Thus, new regulations should be set to reduce infringement of fundamental rights. It is hoped that doctors’ consciousness on new law could be preliminary data to regulate new rules in discussing lower statutes.

Journal of the Korean Medical Association 2023;66(12):728-734
Background:
On September 25, 2023, the law requiring the mandatory installation and operation of closed circuit television (CCTV) in the operating room went into effect. In this study, doctors’ perceptions of the law were re-examined on September 23, 2023 (just prior to the law’s enforcement), following a survey conducted on July 21, 2021 (before the re-examination of the bill). This study aimed to confirm doctors’ perceptions of the infringement of fundamental rights of this law, the collapse of essential medical services due to the avoidance of surgery, and other concerns and priority solutions ahead of the law’s enforcement.
Methods:
The survey was conducted from 8 to 18 September, 2023, by the Korean Medical Association Doctor Survey; a total of 1,267 doctors responded to the survey.
Results:
Out of 1,267 respondents, 1,156 (91.2%) said “yes,” and 111 (8.8%) said “no” to issue concerning constitutional violations of fundamental rights–such as the freedom of medical personnel to practice their profession–and moral rights. A total of 1,149 (90.7%) respondents agreed with the concern regarding the collapse of essential medical care due to the avoidance of surgeons.
Conclusion
Sufficient guidance should be provided, along with guidelines that provide explicit standards for the installation and operation of the CCTV systems, along with safety management measures. Medical disputes and the heavy legal responsibility of medical personnel are the main reasons as to why essential medical care collapses, given the avoidance of surgery. Medical disputes should be avoided in order to prevent essential medical care collapse, as the video is used as evidence for criminal sanctions.

Three cases of lipomas associated with heavy talc deposits are reported in local inhabitants near a fiber glass factory. Pathologic and mineralogical analysis by polarizing microscopy, scanning and transmission electron microscopy with energy dispersive X-ray analysis and X-ray diffraction of mass were done. Simultaneously, we performed an epidemiological survey and a mineralogical study of disposed fiber glass from waste site and ground water. All tumors consisted of mature fat tissue containing an abundant birefringent talc fibers and particles under polarized light. The concentrations of the fibers were 494.7, 6.7 and 50.7 million fibers per gram of dry tissue. The fibers were needlelike with rectangular fractured ends, up to 17 micrometer in length and 0.5 micrometer in diameter. EDX and X-ray diffraction analysis of the fibers showed that 71 to 100% of the fibers were magnesium silicate, talc. We also identified magnesium silicate fibers in the fiber glass from the waste site and in the ground water which were similar to talc fibers in lipomas,. We concluded that fibrous talc, a component of fiberglass waste, might be associated with the development of lipomas via unknown exposure route.

PURPOSE: This cross-sectional survey research was undertaken to identify the factors influencing time from onset to hospital arrival of stroke patients and to provide basic information for the development of intervention programs for stroke patients. METHODS: The data were collected using a convenient sampling method from three hospitals in Inchon. The subjects were 78 patients who were diagnosed as stroke by doctor and they voluntarily participated in the study. RESULTS: On the average, subjects arrived at the hospitals by 16.72 hours after the onset of stroke events with the range from 0.17 hours to 72 hours. Thirty-four(43.6%) subjects arrived within 3 hours which can maximize treatment effects. There was significant difference in hospital presentation time according to the level of knowledge(chi-square=18.629, p=.0003). A negative correlation was found between the hospital presentation time and self-efficacy (r= -.320, p=.004). Stepwise multiple regression analysis revealed that the most powerful predictor was self-efficacy. Self-efficacy, the level of knowledge and physical symptoms were significant factors and accounted for 21.7% of the variance of hospital presentation time in stroke patients. CONCLUSION: According to the results, self-efficacy is a useful concept for reducing the hospital presentation time from onset of attack in stroke patients. Therefore, nurses should consider educational programs which include not only a knowledge of stroke and recurrence prevention but also the concept of self-efficacy.

An outbreak of dermatosis occurred in a livestock fodder factory at Kyongju in May 1994. Authors conducted a questionnaire survey on 60 workers in the factory and a dermatologist examined their skin lesion. Authors also collected mites and identified them. The obtained results were summarized as follows; 1. Twentyeight cases of dermatosis were identified with attack rate of 46.7%. Attack rate was not different by department, age, sex, educational level and employment duration. Attack rate was 67.5% in productive worker and 5.0% in clerical workers (p<0.01) but was not significantly different between departments among productive workers (p>0.05). 2. Three cases among 28 dermatosis cases and one subject among 32 non-cases had a history of same dermatosis last year. Only one of dermatosis cases had a history of dermatosis among family members. History of other skin lesion and allergy was very rare in both cases and non-cases. 3. Skin lesions of the cases were rice-sized erythematous papules or vesicles with a central biting point. Onset date of dermatosis was between May 1 and June 10. Duration was from one day to more than 30 days. Skin lesion was most frequent at the back(75.0%). and also observed at the arms(64.3%). abdomen(60.7%), legs(57.1%), chest(32.1%) and neck (25.0%). Skin lesion was aggravated while workers are sweeping the floor(35.7%), working at the workplace(21.4%) and in bed at night(28. 6%). 4. Total l,637 mites were collected and identified into 3 suborder, 7 families and 17 species. Dermafophagoides farinae was most frequent Nnd most of the species identified were blood sucking mites. Authors concluded that the outbreak of dermatosis was brought about by mite-bites and grain beetle parasitizing Acarophenax tribolii was the most suspected species. Further studies to identify the specific species causing dermatosis and route of import are needed.
