This study examined the causal relationship among the leadership type, organizational commitment, and job performance, and to improve the organizational performance and effective methods of human resource management in hospital organizations. The survey period was from October 6, 2016 to October 20, and 375 employees working in hospitals were selected for the final survey. To analyze the validity of the measurement variables, reliability and confirmatory factor analysis were conducted, and the covariance structure equation analysis was conducted to grasp the causal relationship among leadership, organizational commitment, and job performance. In conclusion, leadership, organizational commitment, and job performance were significantly different according to the occupation(p<0.05), age(p<0.05), and working period(p<0.05), and individual care(p<0.001) and conditional reward(p<0.001) showed a high causal relationship with the organizational commitment and job performance. In the future, leadership that can take care of the individual characteristics of the members of the organization and ability to demonstrate their competence will be needed, and it will be necessary to establish a reasonable compensation system after measuring the degree of achievement of work. In addition, leadership needs to be in place to promote organizational performance considering the job type, gender, age, and duration of work. Managers should make efforts to form an organizational culture and provide related education programs to improve loyalty and attachment of members to the organization.

This study was a pilot test of serious educational game content(named Roly Poly 160) designed to enhance self-care by elderly diabetics. Roly Poly 160 was developed in eight steps (literature review, demand survey and consultation, extraction of serious content using games, development of Roly Poly 160, pretest for users, workshop for health care workers, final completion of Roly Poly 160 and user satisfaction survey of Roly Poly 160). Roly Poly 160 is intuitively structured in three modules (self-management, card games, and quiz games) that can be self-managed by the elderly and is designed based on six principles. First, we constructed an intuitive interface considering the age of users. Second, the menu was selected as the main menu for Koreans and calorie learning was made at the same time. Third, the calories and nutrients (carbohydrate, fat, protein, calcium, sodium) of selected foods are analyzed, and all test data recorded in the questionnaire chart are graphically displayed by year, month and week so that the change trends can be grasped at a glance. Fourth, necessary data were saved and output and used as educational data. Fifth, user data are made compatible and aggregated and up to 100 million members can be registered. Sixth, it is designed to be developed as a mobile app if necessary. Using Roly Poly 160, 119 diabetic patients were diagnosed with diabetes, and the satisfaction score was 4.26 out of 5. These findings indicate that Roly Poly 160 is appropriate as a diabetes self-care tool and suggests that there is a possibility to use it as a program to educate people about diabetes in public health centers, hospitals and clinics.

Objective: This study examined the caregiver burden, depressive symptoms, and mental-related quality of life of 226 caregivers of stroke patients, who had been hospitalized in 7 general hospitals located in Cheongju and Daejeon Metropolitan city. Methods: Data were collected from August 5, 2014 to October 5, 2014 and a structured self-administered questionnaire was used. The results were analyzed using a t-test, ANOVA for different comparisons of the mental related quality of life in the sociodemographic characteristics, care-related characteristics, health-related behavioral characteristics, caregiver burden, and depressive symptoms. Hierarchical multiple regression was conducted to determine the explanatory power of the independent variables on the dependent variables, with the variables showing significant differences in univariate analysis as independent variables. Results: According to the results of hierarchical multiple regression analysis, the relevant factors that influenced the mental-related quality of life were the relationship with a patient, burden by 'care', burden by sacrifice of 'personal life', and depressive symptoms. Conclusion: To enhance health-related quality of life, not only is a systematic complement on such factors needed, but the development and implementation of an intervention program to the caregiver burden and depressive symptoms is also urgently required.

This study intends to examine general hospital workers' health promoting lifestyle practice and figure out related factors to it. To achieve that, it conducted a survey with an unsigned self-reported questionnaire to the subject of 580 workers at hospitals located in Daejeon. The degree of practice in the subjects' health promoting lifestyle, the average of the entire questions was 2.26 points and the average of sub-sections was as in the following: 2.62 for interpersonal relations, 2.58 for spiritual growth, 2.26 for nutrition, 2.16 for stress management, 2.00 for health responsibility and 1.89 for physical activity Thus, the section of interpersonal relations showed the highest practice rate, whereas the section of physical activity demonstrated the lowest one. According to the multivariate regression analysis by phase, main factors affecting their health promoting lifestyle practice were selected as stress, attendance in education on health promotion, subjective heath condition, and age. The above results imply that general hospital workers' health promoting lifestyle practice is not sufficient and various factors are involved in it. Accordingly, it is considered that in order to enhance general hospital workers' attention to health promoting lifestyle practice, it is necessary to develop health promoting strategies and programs.

Background: The study aimed to describe the age distribution of breast cancer diagnosis among Chinese females for comparison with the United States and the European Union, and provide evidence for the screening target population in China. Materials and Methods: Median age was estimated from hospital databases from 7 tertiary hospitals in China. Population-based data in China, United States and European Union was extracted from the National Central Cancer Registry, SEER program and GLOBOCAN 2008, respectively. Age-standardized distribution of breast cancer at diagnosis in the 3 areas was estimated based on the World Standard Population 2000. Results: The median age of breast cancer at diagnosis was around 50 in China, nearly 10 years earlier than United States and European Union. The diagnosis age in China did not vary between subgroups of calendar year, region and pathological characteristics. With adjustment for population structure, median age of breast cancer at diagnosis was 50~54 in China, but 55~59 in United States and European Union. Conclusions: The median diagnosis age of female breast cancer is much earlier in China than in the United States and the European Union pointing to racial differences in genetics and lifestyle. Screening programs should start at an earlier age for Chinese women and age disparities between Chinese and Western women warrant further studies.

Background: Breast cancer risk prediction models are widely used in clinical practice. They should be useful in identifying high risk women for screening in limited-resource countries. However, previous models showed poor performance in derived and validated settings. Therefore, we aimed to develop and validate a breast cancer risk prediction model for Thai women. Materials and Methods: This cross-sectional study consisted of derived and validation phases. Data collected at Ramathibodi and other two hospitals were used for deriving and externally validating models, respectively. Multiple logistic regression was applied to construct the model. Calibration and discrimination performances were assessed using the observed/expected ratio and concordance statistic (C-statistic), respectively. A bootstrap with 200 repetitions was applied for internal validation. Results: Age, menopausal status, body mass index, and use of oral contraceptives were significantly associated with breast cancer and were included in the model. Observed/expected ratio and C-statistic were 1.00 (95% CI: 0.82, 1.21) and 0.651 (95% CI: 0.595, 0.707), respectively. Internal validation showed good performance with a bias of 0.010 (95% CI: 0.002, 0.018) and C-statistic of 0.646(95% CI: 0.642, 0.650). The observed/expected ratio and C-statistic from external validation were 0.97 (95% CI: 0.68, 1.35) and 0.609 (95% CI: 0.511, 0.706), respectively. Risk scores were created and was stratified as low (0-0.86), low-intermediate (0.87-1.14), intermediate-high (1.15-1.52), and high-risk (1.53-3.40) groups. Conclusions: A Thai breast cancer risk prediction model was created with good calibration and fair discrimination performance. Risk stratification should aid to prioritize high risk women to receive an organized breast cancer screening program in Thailand and other limited-resource countries.

Recently, the problem of air pollution has become a global concern due to industrialization and overcrowding. Air pollution can cause various adverse effects on human health, among which respiratory diseases such as asthma, which have been of interest in this study, can be directly affected. Previous studies have used clinical data to identify how air pollutant affect diseases such as asthma based on relatively small samples. This is high likely to result in inconsistent results for each collection samples, and has significant limitations in that research is difficult for anyone other than the medical profession. In this study, the main focus was on predicting the actual asthmatic occurrence, based on data on the atmospheric environment data released by the government and the frequency of asthma outbreaks. First of all, this study verified the significant effects of each air pollutant with a time lag on the outbreak of asthma through the time-lag Pearson Correlation Coefficient. Second, train data built on the basis of verification results are utilized in Deep Learning algorithms, and models optimized for predicting the asthmatic occurrence are designed. The average error rate of the model was about 11.86%, indicating superior performance compared to other machine learning-based algorithms. The proposed model can be used for efficiency in the national insurance system and health budget management, and can also provide efficiency in the deployment and supply of medical personnel in hospitals. And it can also contribute to the promotion of national health through early warning of the risk of outbreak by atmospheric environment for chronic asthma patients.

In this study, we set the occupational satisfaction and communication ability of clinical dental hygienists as the main variables, and investigated the factors that affect communication within the organization to improve the work of dental hygienists. Self-reporting questionnaires were administered to 200 dental hygienists working in dental hospitals and dental clinics in Seoul and Gyeonggi Province from May 18, 2019 to June 12, 2019. We analyzed the data with Pearson correlation analysis and multiple regression analysis. The significance level was set at 0.05. Research results: Job satisfaction (r=0.193, p<0.05) and communication ability (r=0.404, p<.001) showed a significant positive correlation with intra-organizational communication, and individual communication ability (β=0.461, P<.001), which was found to have a significant effect on communication within this organization. Therefore, in order to improve the communication skills of dental hygienists, they should be proud of their work as professionals, enhance their job satisfaction, and be able to have a clear expression of their own intentions and effective dialogue. Efforts should be made to provide opportunities such as opening related lectures during internal education and maintenance education.

This study is a descriptive study which was done to examine the circumstances surrounding burn accidents in children in order to develop a burn prevention program. The subjects for the study were the mothers of 107 children admitted to two burn specialty hospitals in seoul and the mothers of 172 healthy children attending day care or kindergarten. The tool used in the study was developed by the researchers, pretested and refined. Cronbach's alpha was 0.72. Data collection was done between November 1995 and April 1996. Statistically analysis was done using SAS Version 6.04 and the data was analyzed using test, chi square, regression and logistic analysis. A suumary of the results shows the following : Eighty percent of the children in both groups lived in nuclear families but comparatively more of the children with burn accidents lived in apartments. More of the parents in the group of healthy children had university education and held white collar or professional jobs, while the parents of the children with burn accidents were slightly younger than the parents of the healthy children. but not significantly younger. A significantly greater number of families of children with burn accidents had more than one child and the characteristics of the children with burn accidents that they were more frequently boys, either first or last born and very active. Most of the burn accidents occurred in fall or winter. sometime between noon and midnight and the majority occurred in the home and were caused by hot liquid. In 86% of the cases emergency care was not given at home but the child was brought to the hospital emergency unit. Most of the burns were second degree or greater. involved the arms or legs. required admission, and 41.5% occurred when the parents were preparing or eating meals. In a test of knowledge of preventive measures, the mothers of children who had suffered burn accidents scored slightly higher than the mothers who had no experience with burn accidents, but this was not statistically significant. As to what to do in the case of a fire, the mothers of the healthy children had more knowledge about who to notify. but 70% of the mothers in both groups did not know how to escape from the house if it was of fire. 80 to 96% did not know what do to in case of a fire, such as rolling if clothes were on fire. 80% did not know what emergency care to give for a burn, and 74 to 87% did not know when it is appropriate to try to put out a fire. It can be concluded from this study that. since the results show that the most frequent situation which resulted in burn accidents was when the parents were not aware of the danger of burns or were not paying attention to the child. and when there were no protective devices to prevent burns. and that accidents most frequently occurred at home. the most effective way of preventing accidents is to develop in the parents a "safety mind", Since burn accidents in children are usually more severe than in adults. the physical. emotional. psychological and social damage is greater. In order to develop and awareness of this in the general public. the use of mass media. books and pamphlets and other educational media that provide education on prevention of burn accidents need to be utilized.
