This study investigates the stressors of dental hygienists and student hygienists during the bedside training by the medical center type. The survey is based on some dental hygienists who are working for dental college hospitals, general hospitals, dental hospitals and dental clinics in Seoul and Gyeonggi area which the Clinical Practice of dental hygienics students is under way in. Included are the students who are studying dental hygienics at Kyungbok University and have taken the bedside training in dental college hospitals, general hospitals, dental hospitals and dental clinics. A statistical analysis shows the following results using SPSS program. By medical center type, dental hygienists described the clinical practice of students as relatively satisfying. It also found that there is a positive correlation between stress zones, and they feel most stressed in the "Role and Activity" zone. Student hygienists felt relatively satisfied with the bedside training, and there is a positive correlation between stress zones except "Practice". It found students, who have taken the bedside training in all types of medical centers except dental clinics, felt most stressed in "Environment". It also found that students who have taken the bedside training in dental clinics felt most stressed in "Role and Activity". In conclusion, most of the dental hygienists are satisfied with students' clinical practice by pattern of hospital. Positive correlation was shown between stress factors. Behavior and attitude and ideal and value are high in stress in college dental hospitals, role and activity and treatment fields are high in stress in dental hospital, and interpersonal relationships are high in stress in dental clinics.

As the medical environment and dental services change, the importance of educating dentists in responses to systemic emergencies is increasing. The current student-oriented education paradigm is moving towards training students in the abilities required to address the daily crises they will face, while also providing them with the ability to deliver knowledge. Before addressing a patient's situation, emergency physicians begin by diagnosing symptoms. As they must decide on the tests and treatments that are immediately required and must solve problems through interdisciplinary treatment, emergency physicians require additional skills and communication abilities besides clinical knowledge. Since dentistry colleges provide education that emphasizes the skills dentists require to treat oral diseases, they do not have sufficient time to teach emergency care. Additionally, because their professors lack expertise in pedagogy, dental students also have insufficient motivation to study the pathophysiology of systemic diseases. This review proposes a direction of teaching that can help dental students recognize problems and situations in emergency cases and that can help them develop their capability to immediately make a decision and resolve the problem. To do this, the author surveyed the educational philosophy and knowledge provided in the instructional design of clinical professors who give lectures on emergency care, and also examined the teaching methods of the learner-oriented education paradigm.

PURPOSE. The aim of the study was to evaluate the effect of annealing on the nanostructure and hardness of Co-Cr metal ceramic samples that were fabricated with a direct metal laser sintering (DMLS) technique. MATERIALS AND METHODS. Five groups of Co-Cr dental alloy samples were manufactured in a rectangular form measuring $4{\times}2{\times}2$ mm. Samples fabricated by a conventional casting technique (Group I) and prefabricated milling blanks (Group II) were examined as conventional technique groups. The DMLS samples were randomly divided into three groups as not annealed (Group III), annealed in argon atmosphere (Group IV), or annealed in oxygen atmosphere (Group V). The nanostructure was examined with the small-angle X-ray scattering method. The Rockwell hardness test was used to measure the hardness changes in each group, and the means and standard deviations were statistically analyzed by one-way ANOVA for comparison of continuous variables and Tukey's HSD test was used for post hoc analysis. P values of <.05 were accepted as statistically significant. RESULTS. The general nanostructures of the samples were composed of small spherical entities stacked atop one another in dendritic form. All groups also displayed different hardness values depending on the manufacturing technique. The annealing procedure and environment directly affected both the nanostructure and hardness of the Co-Cr alloy. Group III exhibited a non-homogeneous structure and increased hardness ($48.16{\pm}3.02$ HRC) because the annealing process was incomplete and the inner stress was not relieved. Annealing in argon atmosphere of Group IV not only relieved the inner stresses but also decreased the hardness ($27.40{\pm}3.98$ HRC). The results of fitting function presented that Group IV was the most homogeneous product as the minimum bilayer thickness was measured (7.11 ${\AA}$). CONCLUSION. After the manufacturing with DMLS technique, annealing in argon atmosphere is an essential process for Co-Cr metal ceramic substructures. The dentists should be familiar with the materials that are used in clinic for prosthodontics treatments.

Objectives: To examine whether the nursing practice environment at the hospital-level affects the job satisfaction and turnover intention of hospital nurses. Methods: Among the 11 731 nurses who participated in the Korea Health and Medical Workers' Union's educational program, 5654 responded to our survey. Data from 3096 nurses working in 185 general inpatient wards at 60 hospitals were analyzed using multilevel logistic regression modeling. Results: Having a standardized nursing process (odds ratio [OR], 4.21; p<0.001), adequate nurse staffing (OR, 4.21; p<0.01), and good doctor-nurse relationship (OR, 4.15; p<0.01), which are hospital-level variables based on the Korean General Inpatients Unit Nursing Work Index (KGU-NWI), were significantly related to nurses' job satisfaction. However, no hospital-level variable from the KGU-NWI was significantly related to nurses' turnover intention. Conclusions: Favorable nursing practice environments are associated with job satisfaction among nurses. In particular, having a standardized nursing process, adequate nurse staffing, and good doctor-nurse relationship were found to positively influence nurses' job satisfaction. However, the nursing practice environment was not related to nurses' turnover intention.

Objectives: The purpose of this study was to prevent health problems and environmental contamination resulting from inappropriate management of dental wastes and to provide reference data for revision and supplementation of dental clinic waste management guidelines. Methods: From 640 total of dental clinics registered in 16 cities and counties in Gyeongsangnam-do, 100 (60 in Changwon (Masan, Changwon), 29 in Gimhae, and 11 in Jinju) were included in this study. From July 2010 to September 2010, investigators visited the 100 dental clinics and conducted survey interviews using a structured survey questionnaire regarding disposal methods for liquid wastes (suction pump, spittoon container waste, used liquid disinfectants, and X-ray developer), and disposal methods for solid waste (suction pump, spittoon container waste, and general medical waste). Results: All the 100 dental clinics were found to treat liquid waste from suction pumps and spittoon containers in the same manner as general waste water. Nineteen percent of the clinics treated solid waste that was not filtered through the filter of a suction pump as general waste. Fifty or more percent of the clinics treated solid waste in spittoon containers as general waste. Seventy percent of the clinics used disinfectant solution, although most of them treated used disinfectants in the same manner as general waste water. Some clinics treated used X-ray developer and X-ray fixer in the same manner as general waste water. In most of the clinics, used drapes were washed within the clinic. Conclusions: It was found that waste water and dental wastes at some dental clinics were treated in inappropriately. Thus, in conclusion, the development of guidelines regarding proper management of liquid and solid dental waste at dental clinics is required, and hygiene and environmental training for workers at dental clinics is necessary.

Objectives: The purpose of this study is to identify the effects of dental hygienists' cooperation and compensation satisfaction on job embeddedness through positive psychological capital, and to provide basic data on ways to improve the welfare of dental hygienists and the quality of medical services. Methods: From July 1 to 20, 2023, a questionnaire survey was administered to 206 dental hygienists via an online link. SPSS Statistics ver. 22.0 was used to conduct the frequency analysis, t-test, one-way ANOVA, Pearson's correlation coefficient, multiple regression analysis and hierarchical multiple regression. Results: Factors influencing dental hygienists' job embeddedness were type of compensation satisfaction (β=0.362, p<0.001), intangible compensation satisfaction (β=0.190, p<0.001), cooperation between dental hygienists (β=0.178, p<0.05), and age (β=0.112, p<0.05). Positive psychological capital was found to have a complete mediating effect on work cooperation in the effect of dental hygienists' job embeddedness (p>0.05), and partial mediating effect on compensation satisfaction (p<0.01). As a result of the Sobel test, it was confirmed that it was statistically significant as dental hygienist work cooperation (Z=2.339, p=0.019), dentist work cooperation (Z=1.985, p=0.047), intangible compensation satisfaction (Z=2.286, p=0.022), and type compensation satisfaction (Z=1.980, p=0.048). Conclusions: In order to improve the work environment of dental hygienists, develop programs to improve positive psychological capital, secure access to education, and various related studies are needed.

Many patients with mental retardation need extensive dental treatment because they have much difficulty in maintaining their oral hygiene. However, because they are not cooperative and not manageable, they require physical restraints, drug induced sedation or general anesthesia. General anesthesia is useful in control of the patients who cannot be treated in other ways. Additionally, general anesthesia provides more safe environment for medically compromised patients. And medical treatment can be provided simultaneously under general anesthesia. Furthermore, almost all treatment can be provided without visiting several times. This case reports of periodontal, restorative and ophthalmological treatment of patient with mental retardation under general anesthesia.

Lately, national hygiene & medical environment and its demand aspect have been rapidly changing, and market opening of hygiene and medical sector is accelerating. Due to the change in labor resulting from the wide range of change in industrial structure and the steady decrease in university applicants, most of colleges and universities have been strongly urged to establish hygiene medical manpower training courses or relative courses, which leaves the medical technician training courses in 4 year universities on the robust increase. Consequently, the medical technicians, graduating from 3 year colleges without bachelor's degree due to shortage of 20 credits for acquisition of degree, have had to compete with the graduates from 4 year universities and the bachelor's degree has been in continuous demand for the medical technicians of 3 year college. In the research for recognition of Credit Bank System prevalent across the colleges, enabling the systematic acquisition of bachelor's degree, 60.9% among the respondents are aware of Credit Bank System, and 46.9% are aware that Advanced Major Course is induced in the near future. Hence, there shall be active promotions of various programs allowing acquisition of bachelor's degree in the colleges. The social change in recognition of colleges by inducement of the two programs may authorize the college to have the scholastic attainments equivalent to the 4 year university, and the political initiative shall be deliberated across over the government and the academic world.

Purpose: This study examines the clinical practice satisfaction and major satisfaction of dental technology students who have experienced clinical practice to identify whether there is an effect on employment intention of satisfaction level as a basis for increasing the employment rate of dental technicians. Methods: A survey was distributed among 150 dental technology students, and the data were analyzed using descriptive statistics and frequency and correlation analyses. Finally, multiple regression analysis was used to verify the research hypotheses. All statistical analyses were carried out using IBM SPSS Statistics ver. 27.0 (IBM). Results: The students exhibited high levels of satisfaction with their clinical practice (4.20) and dental technology major (4.07). Further analysis showed a positive correlation between intention to work in dental laboratories and satisfaction with a dental technology major (practice; r=0.437, p<0.05); clinical practice organization (r=0.682, p<0.05); and satisfaction with the clinical practice institution (r=0.650, p<0.05). Statistically significant positive associations (p<0.05) were also observed between clinical practice form and environment, satisfaction with dental technology major, and school region (i.e., metropolitan area). Conclusion: The findings of this study suggest that high levels of satisfaction with clinical practice and dental technology major can contribute to increased employment rates among dental technicians by promoting their intention to work in the related industry.
