The purpose of this study is to explore the future direction of university liberal arts classes at a time when many educational institutions have returned to face-to-face instruction as social distancing related to COVID-19 has been eliminated. A survey was conducted with 187 college students who took a liberal arts class that included a combination of online and in-person classes. The results found that learners were generally satisfied with remote learning (87.8%). The reasons for this high level of satisfaction included sufficient comprehension of class content, systematic class progress, and the efficiency and convenience of learning in a remote environment. Satisfaction levels for in-person classes (66%) were relatively lower than those for remote classes, and this is reflected in the preference for class type. Among wholly in-person, wholly remote, and a combination of both, it was found that learners preferred remote classes the most (54.4%). When conducting in-person classes, instructors must devise a class plan that incorporates the advantages of online remote classes.

With increasing demands for medical care by society, the medical system, and general citizens and rapid changes in doctor's awareness, the competencies required of doctors are also changing. The goal of this study was to develop a doctor's competency framework from the patient's perspective, and to make it the basis for the development of milestones and entrustable professional activities for each period of medical student education and resident training. To this end, a big data analysis using topic modeling was performed on domestic and international research papers (2011-2020), domestic newspaper articles (2016-2020), and domestic social networking service data (2016-2020) related to doctor's competencies. Delphi surveys were conducted twice with 28 medical education experts. In addition, a survey was conducted on doctor's competencies among 1,000 citizens, 407 nurses, 237 medical students, 361 majors, and 200 specialists. Through the above process, six core competencies, 16 sub-competencies, and 47 competencies were derived as subject-oriented doctor's competencies. The core competencies were: (1) competency related to disease and health as an expert; (2) competency related to patients as a communicator; (3) competency related to colleagues as a collaborator; (4) competency related to society as a health care leader (5) competency related to oneself as a professional, and (6) competency related to academics as a scholar who contributes to the development of medicine.

This study investigates the influence of particulate matter concentrations on the incidence of asthma, focusing on the delayed onset of symptoms and subsequent medical consultations. Analysis incorporates a four-day lag from the initiation of fine dust exposure and compares asthma patterns before and after the World Health Organization's (WHO) classification of fine dust as a Group 1 carcinogen in November 2013. Utilizing daily PM10 data and asthma-related medical visit counts in Seoul from 2008 to 2016, the study additionally incorporates Google search frequencies and newspaper article counts on fine dust to assess public awareness. Results reveal a surge in search frequencies and article publications after WHO announcement, indicating heightened public interest. To standardize the long-term asthma occurrence trend, the daily asthma patient numbers are ratio-adjusted based on annual averages. The analysis uncovers an increase in asthma medical visits 2 to 3 days after fine dust events. Additionally, greater public awareness of fine dust hazards correlates with a significant reduction in asthma occurrence after such events, even within 'normal' fine dust concentrations. Notably, behavioral changes, like limiting outdoor activities, contribute to this decrease. This study highlights the importance of analyzing accumulated medical data over an extended period to identify general public behavioral patterns, deviating from conventional survey methods in social sciences. Future research aims to extend data collection beyond 2016, exploring recent trends and considering the potential impact of decreased fine dust awareness amid the COVID-19 pandemic.

Purpose : The college student period is pivotal for establishing oral health management behaviors and habits that persist in adulthood; it is necessary to develop the correct behaviors. Appearance management behavior not only involves the management of an individual's appearance but also ensures a healthy quality of life. Additionally, it is related to health and oral health behavior. The purpose of this study was to determine how college students' appearance management behavior affects their oral health management behavior and to provide basic data for developing policies appropriate for the lifestyle of college students. Methods : A self-administered questionnaire was completed by 450 university students in Gyeonggi, Choung-nam, Daejeon on April 27, 2022. The survey comprised 5 questions about general characteristics, 18 about appearance management behavior, and 8 about oral health behavior. The sum of the practice questions were calculated, with higher scores indicating better oral health behavior. Results : The oral health management behavior exhibited was generally high. Notably, the health-related group (61.2 %) demonstrated significantly higher levels of clothing management (60.5 %), makeup management (56.6 %), and skincare (56.6 %) behaviors, whereas body management behavior (61.2 %) was deemed 'normal' (p<.05). The results of the stepwise multiple regression analysis examining the impact of appearance management behavior on oral health management indicated that clothing management (β=0.17) and skincare behaviors (β=0.12) were influential factors. Among these, clothing management behavior was the most influential. Conclusion : To promote oral health practices among college students, this study incorporated factors related to appearance management into oral health education to increase participation and interest. We intend our findings to serve as foundational data for developing oral health education programs that integrate elements of appearance management.

Objective: The objective of this study was to describe the characteristics of exposure to humidifier disinfectants (HDs) and their association with the presence of a person who experienced the adverse health effects in general households in Korea. Methods: During the month of December 2016, a nationwide online survey was conducted on adults over 20 years of age who had experience of using HDs. It provided information on exposure characteristics and the experience of health effects. The final survey respondents consisted of 1,555 people who provided information on themselves and their household members during the use of HD. Exposure characteristics at the household level included average days of HD use per week, average hours of HD use per day, the duration within which one bottle of HD was emptied, average input frequency of HD, amount of HD (cc) per one time used, and active ingredients of HD products (PHMG, CMIT/MIT, PGH, or others). The risk of the presence of a person who experienced adverse health effects in the household was evaluated by estimating odds ratios (ORs) and 95% confidence intervals (CIs) adjusted for monthly income and region using a multiple logistic regression model. Subgroup analyses were conducted for households with a child (≤7 years) and households with a newborn infant during HD use. Results: The level of exposure to HD tended to be higher for households with a child or newborn infant for several variables including average days of HD use per week (P<0.0001) and average hours of HD use per day (P<0.0001). The proportion of households in which there was at least one person who experienced adverse health effects such as rhinitis, asthma, pneumonia, atopy/skin disease, etc. was 20.6% for all households, 25.3% for households with children, and 29.9% for households with newborn infants. The presence of a person who experienced adverse health effects in the household was significantly associated with average hours of HD use per day (P_trend<0.001), duration within which one bottle of HD was emptied (P_trend<0.001), average input frequency of HD (P_trend<0.001), amount of HD per one use (P_trend=0.01), and use of HDs containing PHMG (OR=2.23, 95% CI=1.45-3.43). Similar results were observed in subgroup analyses. Conclusion: Our results suggest that level of exposure to HD tended to be higher for households with a child or newborn infant and that exposure to HD is significantly associated with the presence of a person who experienced adverse health effects in the household.

The main objective of this paper is to examine the working conditions of physical therapists and to investigate the level of job satisfaction and organizational commitment under different working conditions. A survey was conducted through structured questionnaire for the physical therapists working in Busan area, and data from 175 therapists were utilized in the final analysis. Survey items included general characteristics of the therapists(sex, age, education, marital status, religion, income, career years, etc.), their working conditions(kinds of organizations they work in, location of PT room, weekly working hours, average number of patients, number of co-workers, equipments/facilities, etc.), and organizational effectiveness measured in terms of job satisfaction and organizational commitment. Major results are as follows: 1) As for the general characteristics of the surveyed physical therapists, male(51.4$\%$) slightly exceeded female(48.6$\%$) and majority(more than 90$\%$) was 20-39 in age. Also, there were more single(57.7$\%$) than married(42.3$\%$), and 54.9$\%$ of the respondents had religion while 45.1$\%$ did not. In terms of the ranks in their organizations, only a few of them(6.9$\%$) were managers, and monthly salary mostly ranged from $\￦$1,000,000 to $\￦$2,500,000. More than half of them worked in various kinds of hospitals, with the remaining in health centers or social welfare institutions. 2) In regard to the working conditions of the respondents, 19.4$\%$ of PT rooms were located in basement areas while the remaining 80.6$\%$ in first to third floors. 34.3$\%$ of them treated 15 patients or less per day, whereas 25.1$\%$ treated 31 patients or more. Also, 52$\%$ recorded physical therapy charts periodically. As for the equipments and facilities, 25.1$\%$ felt 'sufficient' and 40$\%$'insufficient.' 3) The respondents provided various kinds of suggestions for the improvement of their working conditions, where the most important were 'salary raise' and 'reduction of working hours.' In addition, their requests to the PT Association included 'permission of opening of independent practice,' 'permission of legal specialty,' and 'vitalization of the Association.' 4) The comparative analysis of job satisfaction and organizational commitment among different characteristics of the respondents revealed that there was no significant difference between male and female, but in terms of age, the group of 40 or older was highest in both aspects. Besides, therapists who had 15 or more years of hospital career reported higher job satisfaction and organizational commitment than the others. It was also found that the level of organizational commitment increased as the rank of the respondents got higher. There were no significant differences in terms of marital status and religion. 5) Comparison with regard to working conditions showed that therapists employed in university hospitals, health centers and social welfare institutions felt higher job satisfaction and organizational commitment than those in community hospitals and clinics. Also, respondents who worked in basement areas had significantly lower job satisfaction than otherwise. The length of weekly working hours did not really affect the level of job satisfaction, but it was important to maintain 'regular working hours' for the hospitals to improve the employees' organizational commitment. As for the number of patients per day, 'medium level' (21-25 patients) had highest scores in both aspects. And, finally, sufficiency of equipments and facilities was found to be important for the improvement of organizational commitment.

Purpose: This study aimed to examine social networking service (SNS) use and recommended information utilization (SURU) according to the food-related lifestyles (FRLs) of consumers and analyze how the interaction between the FRL and SURU affects the practice of eating alone and visiting restaurants. Methods: Data on 4,624 adults in their 20s to 50s were collected from the 2021 Consumer Behavior Survey for Food. Statistical methods included factor analysis, K-means cluster analysis, the complex samples general linear model, the complex samples Rao-Scott χ² test, and the general linear model. Results: The following three factors were extracted from the FRL data: Convenience pursuit, rational consumption pursuit, and gastronomy pursuit, and the subjects were classified into three groups, namely the rational consumption, convenient gastronomy, and smart gourmet groups. An examination of the difference in SURU according to the FRL showed that the smart gourmet group had the highest score. The result of analyzing the effects of the FRL and SURU on eating alone revealed that both the main effect and the interaction effect were significant (p < 0.01, p < 0.001). The higher the SURU, the higher the frequency of eating alone in the convenience pursuit, and gastronomy pursuit groups. The main and interaction effects of the FRL and SURU on the frequency of eating out were also significant (p < 0.01, p < 0.001). In all the FRL groups, the higher the SURU level, the higher the frequency of visiting restaurants. Specifically, the two groups with convenience and gastronomic tendencies showed a steeper increase. Conclusion: This study provides important basic data for research on consumer behavior related to food SNS, market segmentation of restaurant consumers, and development of marketing strategies using SNS in the future.

Background: There were many reports about the clinical aspect and outcomes of pulmonary tuberculosis in health center but few in a medium sized general hospital. The purposes of this study were to find any characteristic differencies in the patients and the general outcomes of the treatments and also to give some suggestive points for the insurance policy making. Methods: We made a retrograde analysis of the medical records of 1981 patients (male 992 female 1,059) who attended our clinics of the 4th internal department, Daedong general hospital during two years from January 1989 to December 1990. Result: 1) Of 1981 patients, 96 were diagnosed as pulmonary tuberculosis taking relatively large proportion in the prevalence. The ratio of prevalence between male and female was 7.81% to 2.27%. The 61.46% were the first diagnosis & initial treatment cases and the remaining 38.54% were the retreatment cases with no statistical significance between sex. 2) The most prevalent age group was between 21~40 years old and the prevalence rate was 45.45% of male and 76.76% of female. The lowest age group in male patient was above 61 showed 3.03%, and there was no female patients above age 60 years old. This phenomena could be thought as the negligence for the treatment of pulmonary tuberculosis in the old age groups rather than true tuberculosis prevalence and it could be proved by the higher rates towards old age groups in the national tuberculosis prevalence survey. 3) There were 57.07% of the minimal case, 48.96% of the moderate, 18.75% of the far advanced. The sputum examination showed 37.07% were culture positive, 46.88% were the negative, and 15.63% of the patients had no stutum examination. Moreover, uncoperatives among the far advanced cases were notable showing 22.22% of the stutum examination, where 16.13% in the minimal cases. The stutum positive rate among the initial treatment cases were 41.07% and 55.00% for the retreatment cases. The sputum no examination rates were 17.86% and 12.50% respectively. 4) The classfication of the mode of disease onset showed 68.75% with gradual onset, 9.38% hemoptic, 3.13% acute pneumonic and 18.75% was found through the radiologic examination in various occasions. 5) The percentages of patients who continued their treatment for more than 8 month were 35.71% (for initial treatment), 25.00% (for retrement), 16.13% (for the minimal), 27.78% (for the far advanced). 6) The group of patients who were treated more than 8 months showed the negative conversion rate of 80% on sputum and marked improvement on chest x-ray in 56.67%. However, in far advanced or retreatment cases, the rate of negative conversion on sputum and the rate of improvement on chest x-ray were low being 60% and 20% for the former and 60% and 10% for the latter, each respectively. Conclusion: It would be strongly emphasized that the improvement of National medical insurance system and social welfare system in Korea must be definite to improve overall treatment and control of tuberculosis diseases as well as physician's devotious National tuberculosis control policy.

Introduction. Despite the fact that half of premature deaths are caused by unhealthy lifestyles such as smoking tobacco, sedentary lifestyle, alcohol and drug abuse and poor nutrition, there are no theoretical models which accurately explain these health promotion related behaviors. This study tests a new model of health behavior called the Model of Health Promotion Behavior. This model draws on elements and frameworks suggested by the Health Belief Model, Social Cognitive Theory, the Theory of Planned Action and the Health Promotion Model. This model is intended as a general model of behavior but this first test of the model uses amount of exercise as the outcome behavior. Design. This study utilized a cross sectional mail-out, mail-back survey design to determine the elements within the model that best explained intentions to exercise and those that best explained amount of exercise. A follow-up questionnaire was mailed to all respondents to the first questionnaire about 10 months after the initial survey. A pretest was conducted to refine the questionnaire and a pilot study to test the protocols and assumptions used to calculate the required sample size. Sample. The sample was drawn from 2000 eligible participants at two blue collar (utility company and part of a hospital) and two white collar (bank and pharmaceutical) companies located in Southeastern Michigan. Both white collar site had employee fitness centers and all four sites offered health promotion programs. In the first survey, 982 responses were received (49.1％) after two mailings to non-respondents and one additional mailing to secure answers to missing data, with 845 usable cases for the analyzing current intentions and 918 usable cases for the explaining of amount of current exercise analysis. In the follow-up survey, questionnaires were mailed to the 982 employees who responded to the initial survey. After one follow-up mailing to non-respondents, and one mailing to secure answers to missing data, 697 (71.0％) responses were received, with 627 (63.8％) usable cases to predict intentions and 673 (68.5％) usable cases to predict amount of exercise. Measures. The questionnaire in the initial survey had 15 scales and 134 items; these scales measured each of the variables in the model. Thirteen of the scales were drawn from the literature, all had Cronbach's alpha scores above .74 and all but three had scores above .80. The questionnaire in the second mailing had only 10 items, and measured only outcome variables. Analysis. The analysis included calculation of scale scores, Cronbach's alpha, zero order correlations, and factor analysis, ordinary least square analysis, hierarchical tests of interaction terms and path analysis, and comparisons of results based on a random split of the data and splits based on gender and employer site. The power of the regression analysis was .99 at the .01 significance level for the model as a whole. Results. Self efficacy and Non-Health Benefits emerged as the most powerful predictors of Intentions to exercise, together explaining approximately 19％ of the variance in future Intentions. Intentions, and the interaction of Intentions with Barriers, with Support of Friends, and with Self Efficacy were the most consistent predictors of amount of future exercise, together explaining 38％ of the variance. With the inclusion of Prior Exercise History the model explained 52％ of the variance in amount of exercise 10 months later. There were very few differences in the variables that emerged as important predictors of intentions or exercise in the different employer sites or between males and females. Discussion. This new model is viable in predicting intentions to exercise and amount of exercise, both in absolute terms and when compared to existing models.
