Objectives: Dental caries and periodontitis are major oral bacterial infections associated with dental plaque. Infection and inflammation play a role in carcinogenesis, and a significant link has been found between some highly prevalent oral and dental diseases and some types of cancer. Therefore, the aim of this study was to evaluate the relationship between cancer and oral health among Korean adults. Methods: Data from the 6th Korea National Health and Nutrition Examination Survey were used to analyze the incidence of cancer according to oral health. Demographic and socioeconomic statuses and oral behavior of the participants was analyzed using complex chi-square tests. Logistic regression was used to analyze the relationship between a high DMFT index and cancer by calculating the 95% confidence intervals. Results: In total, 6,450 case-control subjects were included. Significant difference was observed in the DMFT index, but not in periodontal diseases, between the cases and controls. The odds ratio for cancer was 1.80 (95% confidence interval: 1.18 to 2.73) in the high-risk group. However, no significant difference was observed after adjusting for age, education level, and income. Conclusions: The results provide potential evidence of a significant association between cancer and oral disease.

Purpose: The purpose of this descriptive research is to identify how stress from Covid-19, health beliefs, and social support of college students affect health prevention. Methods: The subjects of the study were 128 university students, excluding health major students, at one university in D City. The survey was conducted from August 1 to 31, 2020. The survey questionnaire consists of 8 items on stress from COVID-19, 12 items adapted from a health belief measurement tool, 12 items from a social support measurement tool, and 11 items adapted from a tool that measures health preventive behaviors. The collected data were analyzed using the hierarchical multiple regression analysis method with SPSS 26.0. Results: In model 1, stress from COVID-19 was statistically significant (β=-.403, p=.003). Model 2 added four health belief factors into Model 1. Stress (β=-.419, p<.001), perceived severity (β=-.193, p=.030), and perceived barriers (β=-.182, p=.009) were statistically significant. In model 3, stress (β=-.413, p<.001), perceived barriers (β=-.147, p=.034), and social support (β=.194, p=.011) were statistically significant. The regression equation was significant (F=15.395, p=<.001) and the model's explanatory power was 53.1%. Conclusion: The results show that when college students had a high degree of health beliefs about COVID-19, the degree of health preventive behaviors was proportionally high. To make them practice preventive health behaviors, it is necessary to develop infection control education programs to improve health beliefs.

Purpose: This study was conducted to identify factors affecting COVID-19 vaccination and associated side effects among health care workers in a small and medium-sized hospital. Methods: In May 2021, 301 workers out of a total of 670 working in a small and medium-sized hospital in Gyeonggi-do, were surveyed. The small and medium-sized hospital treats patients with COVID-19. Health care workers across different medical institutions responded with self-reported internet questionnaires. Factors influencing COVID-19 vaccination were analyzed via logistic regression. Results: Out of 301 subjects, 89.0% showed an intention to inoculate, and 85.7% were vaccinated against COVID-19. The most frequent reason for vaccination was responsibility as a medical worker. The fear of adverse reactions was the most frequent reason for non-vaccination. Adverse reactions after inoculation occurred in 70.9% of cases, and 30.6% were referred for treatment of adverse reactions. The factors ultimately influencing COVID-19 vaccination were vaccination intention, previous side effects from other vaccinations, occupation, and age. Conclusion: In order to improve the effectiveness of COVID-19 vaccination, a systematic approach is required to determine the risk factors associated with the young age of the administrative staff/personnel, subjects with a history of side effects associated with other vaccines, and health care workers who do not intend to be vaccinated. It is important to develop strategies to improve immunization. In addition, accurate and essential information regarding the side effects of vaccination is needed, along with appropriate education and publicity.

Objectives: The purpose of this study was to investigate the current status of dental hygiene curricula related to clinical practice in Korea. Methods: Clinical work included the categories 'history taking, infection control, oral prophylaxis, preventive treatment, education/counseling, radiography/reading, assisting/cooperation, impression/bite registration, anesthesia, etc.', and 66 works were finally selected based on the frequent tasks of dental hygienists. The subjects were made to answer nine questionnaires. Results: It was found that the theory and practice of the main works operated quite differently in lectures and practice in each school. All types of practice were applied to all schools in the case of 'scaling'. The evaluation of clinical practice was also found to be very different from school to school. Conclusions: For dental hygienists to establish expertise in clinical practice and promote quality improvement, it is necessary to develop a core curriculum focusing on clinical practice. The standardized curriculum should be improved to an efficient and competency-centered one defining clearly the role of dental hygienists considering the needs and importance of clinical practice.

Purpose: Nursing students face constant threats of blood-borne infections such as HIV, Hepatitis B, and Hepatitis C during their clinical rotation period. This study was done to determine the frequency and risk of the exposure to blood and body fluids. Methods: The data was collected using a questionnaire. Ninety eight junior & senior nursing students were participated in this study. Results: 75.6% of the participants reported more than once during practicum. The exposure occurred most frequently while checking the blood glucose (65.3%). The general ward (45.3%) was the most frequent site for the occurrence of the exposure. However, only eight cases (10.7%) were reported to the medical or nursing personnel in charge. Conclusions: This study shows nursing students are in a great risk of the exposure to blood & body fluid. The risk is highest in the general ward during checking the blood glucose. Thorough education on preventive measures, should be provided to nursing students prior to clinical practium.

Objectives : Gastric cancer is the most common incident cancer in Korea. Although Helicobacter pylori infection is the most important risk factor for the development of gastric cancer, cigarette smoking has also been suggested to play an important role in the development of gastric cancer. The objective of this study is to evaluate the relationship between cigarette smoking and gastric cancer risk in a Korean population. Methods : The study population consisted of 13,785 subjects who had been enrolled in the Korean Multi-Center Career Cohort between 1993 and 2002. As of December 2002, 139 incident gastric cancer cases were ascertained through the Korea Central Cancer Registry and the National Death Certificate Database. Relative risks (RR) and 95% confidence intervals (CI) for gastric cancer were estimated using Cox#s proportional hazard model adjusted for age, education, alcohol drinking status and history of gastritis or ulcer. Results : Significant dose-response relationships were observed between the duration of smoking and the risk of gastric cancer among the male subjects in comparison to non-smokers: men who smoked for 20-39 years had a 2.09-fold (95% CI 1.00-4.38) increase, and those who smoked for more than 40 years had a 3.13-fold (95% CI 1.59-6.17) increase in the risk of gastric cancer ($P_{trend}<0.01$). Conclusions : This study suggests that a longer duration of cigarette smoking may increase the risk of gastric cancer development in a dose-response manner in Korean men. The association between smoking and gastric cancer risk in women should be verified in future studies with a larger number of cases.

Rice bakanae is a typical seed-borne and seed-transmitted disease caused by infection by Fusarium fujikuroi. Seed disinfection using chemical fungicides (such as benomyl and prochloraz) is most effective in controlling the disease, but the emergence of fungicide-resistant strains has recently been increasing. Slightly acidic hypochlorous acid water (SAHW) is a safe and environmentally friendly disinfectant that has a potent and broad spectrum of antimicrobial activity against viruses, bacteria, and fungi. In this study, we aimed to investigate the effectiveness of SAHW against F. fujikuroi strains, including chemical fungicide-resistant strains, as an alternative to conventional chemical fungicides in the management of bakanae disease. SAHW showed strong but similar levels of antifungal activity among the F. fujikuroi strains with a minimum inhibitory concentration (MIC₉₀) of 5±2.5 ppm of free available chlorine (FAC). In addition, F. fujikuroi cells lost viability completely within 5 min of SAHW treatment due to the lethal damage to cell integrity. When the rice seeds infected by F. fujikuroi were treated with SAHW containing 20±10 ppm of FAC for 12 hr, the efficiencies of seed disinfection and disease control were 95-98% and 90.1-92.6%, respectively. Altogether, our data suggest that SAHW is an effective compound for controlling rice bakanae disease.

Purpose: The purpose of this study is to analyse research trends related to the evaluation of quality of nursing, thereby obtaining basic data relating to the identification of current situation of instrument development of quality of nursing, and of future research orientation and to the development of performance index of nursing organization. Method: The data were collected from June to December, 2002 through the review of total of 32 research papers which had evaluated quality of nursing among published papers in Korea from 1976 to August 2002. The analysis was done in terms of research period, the periodicals in which research papers were published, domains and the approaches of evaluation of nursing quality. The content analysis of lowest-level items amounting was performed using NIC developed by McCloskey & Bulecheck(1998) and consequential indices of quality of nursing developed by Chi(1995). Results: Twenty-three of 32 papers(71.8%) turned out to be published after 1995, indicating surging interest in the evaluation of quality of nursing from the mid 1990s. Also, ten of 12 research papers dealing with subjects' diseases were published after 1995. In content analysis of lowest-level items of the process-oriented evaluation of quality of nursing, the highest nursing intervention was patient education about procedure and treatment; followed in descending order by patient education about disease process, strengthening of communication, managing environment, infection control, admission care, defecation and urination care. In content analysis of lowest-level items of the outcome-oriented evaluation of quality of nursing, items of physical and psychological state, of patient and family satisfaction, of knowledge and home care, of change of patients' state, of addressing nursing issues, and of patient recovery were the outcome indicators in more than 60 percent research papers. Conclusion: The findings provided the foundation for their effective use in nursing practice with comparing and presenting various core evaluation items representing process and outcome domains.

This research was conducted to understand and analyze the health-related behaviors of middle school students and get fundamental research data essential to provide efficient student guidance and public health service at school. The interview using Youth Risk Behavior Surveillance System(YRBSS). Translation and modification for Korean students of the YRBS. The Korean version of YRBS(Youth Risk Behavior Surveillance System) that translation and modification for Korean students of the YRBS developed by the Centers for Disease Control and Prevention(CDC)was used to assessment to health-related behaviors of youth. The interviewees were 1040 enrolled students at middle school in Daegu metropolitan city. YRBSS monitors six categories of priority health behaviors among youth and young adults behaviors that contribute to unintentional and intentional injuries; tobacco use; alcohol and other drug use, sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases(STDs)(including human immunodeficiency virus infection); unhealthy dietary behaviors; and physical activity. The result shows that over 30% of students rarely or never used safety belt and almost students were rarely or never wore a bicycle helmet. During the 12 months preceding the survey, 21.9% female students had felt so sad or hopeless almost every day for $\geq$ 2weeks in a row that they stopped doing some usually activities 20.5% of male middle school students have ever tried cigarette smoking. 26.2% of male students and 27.2% do female students had had over one drinks of alcohol during their lifetime(lifetime alcohol use). 47% of male students had had over one drinks of alcohol on $\geq$ 1 of the 30 days preceding the survey(current alcohol use). Over one half of female student were thought they were overweight. These results suggest that some risk behaviors be very prevalent in a korean middle school students and priority health-risk behaviors, which contribute to the leading cause of mortality and morbidity among youth and adult, often are establish during middle school age, extend into adulthood, are interrelated. Among both children and adults, the leading causes of death are closely linked to these behaviors. Among adults, chronic diseases such as cardiovascular disease, cancer, and diabetes are the national leading killers. Practicing healthy behaviors, such as eating low-fat, high-fruit-and-vegetable diets, getting regular physical activity, and refraining from tobacco use, would prevent many premature deaths. Because health-related behaviors are usually established in childhood, positive choices need to be promoted before damaging behaviors are initiated or become ingrained.
