Background: Breaking the chain of disease transmission from overseas is necessary to control new infectious diseases such as coronavirus disease 2019 effectively. In this study, we developed a mobile app called Self-Symptom Checker (SSC) to monitor the health of inbound travelers. Methods: SSC was developed for general users and administrators. The functions of SSC include non-repudiation using QR (quick response) codes, monitoring fever and respiratory symptoms, and requiring persons showing symptoms to undergo polymerase chain reaction tests at nearby screening stations following a review of reported symptoms by the Korea Disease Control and Prevention Agency, as well as making phone calls, via artificial intelligence or public health personnel, to individuals who have not entered symptoms to provide the necessary information. Results: From February 12 to March 27, 2020, 165,000 people who were subjected to the special entry procedure installed SSC. The expected number of public health officers and related resources needed per day would be 800 if only the phone was used to perform symptom monitoring during the above period. Conclusion: By applying SSC, more effective symptom monitoring was possible. The daily average number of health officers decreased to 100, or 13% of the initial estimate. SSC reduces the work burden on public healthcare personnel. SSC is an electronic solution conceived in response to health questionnaires completed by inbound travelers specified in the World Health Organization International Health Regulations as a requirement in the event of a pandemic.

This study shares details on the operating process and results of the cohort of students and graduates that was designed and implemented at Konyang University College of Medicine in Daejeon and discusses future directions for cohort establishment and improvement. First, Konyang University College of Medicine established the necessity and defined the purpose of cohort design and implementation. A task force was formed to establish guidelines for analysis targets, procedures, reports, and data management, and cohort operation was classified as a quality control activity. Data were collected through surveys of current students and graduates, and data generated during the curriculum were collected, analyzed, and reported every 2 years. The cohort data collection and analysis methods are designed by the Department of Medical Education, and data collection is carried out by the administrative team and each committee. Data management and analysis are handled by the Center for Medical Education Support, and analysis and reporting are conducted by the Department of Medical Education. Various members of the medical school are working to collect and analyze data, report findings, provide feedback, and improve. In the future, we plan to advance database computerization and work toward more effective data analysis. Cohort operation should not be another burden for medical schools; instead, it is hoped that operating cohorts will be a meaningful activity to increase the effectiveness of medical education and help in the operation and policy decisions of medical schools.

Background: Heat stress is a harmful physical hazard in many occupational settings. However, consequences of occupational heat exposure among workers in a sugarcane factory in Ethiopia are not well characterized. This study aimed to assess the level of occupational heat exposure-related symptoms and contributing factors. Methods: In this cross-sectional study, five workstations were selected for temperature measurement. Heat stress levels were measured using a wet-bulb globe temperature index meter. A stratified random sampling technique was used to select 1,524 participants. Heat-related symptoms were assessed using validated questionnaires. Results: The level of occupational heat exposure was 72.4% (95% CI: 70.2%-74.8%), while 71.6% (95% CI: 69.3%-74.9%) of participants experienced at least one symptom related to heat stress. The most common heat-related symptoms were swelling of hands and feet (78%), severe thirst (77.8%) and dry mouth (77.4%). The identified risk factors were a lack of reflective shields (AOR: 2.20, 95% CI: 1.53, 3.17), not-enclosed extreme heat sources (AOR: 1.76, 95% CI: 1.23, 2.51), a lack of access to shade (AOR: 9.62, 95% CI: 6.20, 14.92), and inappropriate protective clothing provision (AOR: 1.58, 95% CI: 1.27, 2.71). Conclusions: The burden of occupational heat exposure and heat-induced symptoms was high. Lack of reflective shields, the absence of enclosed extreme heat sources, a lack of access to shade, and inappropriate protective clothing provision were considerable attributes of heat stress. Therefore, the use of mechanical solutions to stop heat emissions at their sources and the key factors identified were areas for future intervention.

Advancements of medical care with the use of new medical technologies have been promoting public health, but they can also place a financial burden on individuals and the country. Since the introduction of the health insurance system in 1977, the South Korean government has been attempting to control medical expenses. Radiological examinations have been a major target for cost reduction. Meanwhile, the radiological report fee has been combined with the technical fee for a long time; hence, its value has not been independently evaluated, and was also decreased proportionally with examination cost reduction. However, in the revised medical fee estimation system for MRI, the report fee has begun to be calculated separately from the technical fee, significantly contributing to the evaluation of the radiologists' work value. In conclusion, radiologists need to know and actively participate in the process of determining the insurance cost of radiological examinations and reports to get a proper value of their professionalism.

This study was carried out to verify the relationship between the job satisfaction and turnover intention of nurses working in general hospitals The study included 312 nurses working in three general hospitals located in Gyeoungpook area. The data was collected by a survey using self-administered questionnaires structured from February 25 to March 16, 2013. The level of turnover intention was negatively correlated with job satisfaction and professional position, autonomy, administrative capacity, pay, task requirement. In logistic regression analysis, the adjusted odds ratio of the high risk turnover intention was increased significantly in the lower groups of job satisfaction, job autonomy, administrative capacity and pay than in the higher groups of these items. Hierarchical multiple regression analysis showed that the turnover intention correlated significantly with the education level, subjective sleep evaluation, job career, job position, monthly pay, satisfaction with work, fitness of the job, career choice motives, physical burden of work, and job satisfaction. In addition, there was a negative correlation between the job satisfaction and turnover intention in the studied nurses, which showed that the turnover intention increased with decreasing level of job satisfaction. The variations in the job related characteristics and job satisfaction have a significant influence on the turnover intention.

First, as the result of analysis how the guard's workplace bullying affects job satisfaction, one of the job attitude, it showed that relational aggression and workplace bullying have a negative effect on their job satisfaction. In other words, job satisfaction decreases as relational aggression and workplace bullying increase. Second, as the result of analysis how the guard's workplace bullying affects their turnover intention, we found that relational aggression and workplace bullying have an effect on turnover intention, especially, relationally workplace bullying has a more effect on their turnover intention than relational aggression, which Is somewhat different from other studies. Study shows that workplace bullying can cause the guard's negative respond and behavior on their job satisfaction, they have to consider transferring another job. Therefore, increasing their job satisfaction and decreasing turnover intention are very important as we are exposed to crimes these days. In this study, we have come with following solutions. First, to increase job satisfaction against workplace bullying, we have to raise the efficiency of their human resources and reduce work ambiguity of actual work burden caused by positive organizational atmosphere and clear responsibility. Second, it is needed to promote personnel exchange between departments and form partnership through regular meetings by targeting common goals to concentrate same interests.

The aim of this study was to explore the work experiences of hospital-based child protection team staffs who had intervened the child abuse cases resulting in death. In order to gather the relevant data, all 62 child protection teams registered nationwide were contacted and 5 teams which had actually experienced at least one child abuse deaths were found. The staffs (hospital social workers and doctors) who belonged to these teams were intensively interviewed, and the interviewed materials were thoroughly analyzed by qualitative research methodology. The result showed that treatment delay was the most important obstacle to prevent unnecessary deaths of the victims. Some abused victims were sent to the hospital only after their physical condition had so gravely deteriorated. In other cases, custodians' bland denial or refusal to treatment made impossible the timely intervention to save the child lives. Nevertheless, child protection team staffs' reasonable suspicion and active intervention could sometimes uncover the hidden truth that child abuse was the actual cause of death. These incidents were regarded as a team's meaningful accomplishments by team members. Meanwhile, lack of awareness and excessive burden about the role and responsibility of mandated reporter precluded medical staffs' active involvement. Also, substantiating the abuse suspicion by securing positive evidences was found to be a facilitatory factor for the rapid public intervention. On the basis of these results, several practice and policy implications were discussed to improve the early detection process, securing evidence and uncovering the actual cause of death in child abuse deaths.

In this paper, we introduce a novel method to predict next update of blogs. The number of RSS feeds registered on meta-blogs is on the order of several million. Checking for updates is very time consuming and imposes a heavy burden on network resources. Since blog search engine has limited resources, there is a fix number of blogs that it can visit on a day. Nevertheless we need to maximize chances of getting new data, and the proposed method which predicts update probability on blogs could bring better chances for it. Also this work is important to avoid distributed denial-of-service attack for the owners of blogs. Furthermore, for the internet as whole this work is important, too, because our approach could minimize traffic. In this study, we assumed that there is a specific pattern to when a blogger is actively posting, in terms of days of the week and, more specifically, hours of the day. We analyzed 15,119 blogs to determine a blogger's posting preference. This paper proposes a method to predict the update probability based on a blogger's posting history and preferred days of the week. We applied proposed method to 12,115 blogs to check the precision of our predictions. The evaluation shows that the model has a precision of 0.5 for over 93.06% of the blogs examined.

This study determined the relationship between organizational conflicts and job satisfaction of administrative staff members employed in university hospitals. The sample consisted of 232 hospital administrators working at four different college hospitals located in D city. The survey was conducted using a self-administered questionnaire during the period from January 10th 2019 to February 15th 2019. As a result of the study, the job satisfaction levels were significantly different according to age, education, BMI, subjective sleep evaluation, subjective health status, job position, monthly income, physical burden of work, sense of satisfaction at work, fit to the job and consideration to quit the job. The job satisfaction levels according to the organizational conflicts were significantly lower with higher organizational conflicts. Further, the job satisfaction level showed a significant negative correlation with organizational conflicts. The risk ratio of lower job satisfaction significantly increased for the group with higher organizational conflict scores than that of the group with lower organizational conflict scores. The results suggest that job satisfaction of administrative staff at university hospitals is significantly related with organizational conflicts. It is necessary to present specific measures to resolve conflicts within an organization in order to enhance job satisfaction for administrative staff at university hospitals.
