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.

Purpose: The purpose of this study was to identify the influencing effects of job stress, professional autonomy, and reciprocity on the job embeddedness among comprehensive nursing care unit nurses. Methods: The participants in this study were 147 nurses who have worked for over 6 months in Comprehensive Nursing Care Unit. Data were collected from January 3 to January 31, 2022 from six general hospitals with more than 300 beds in three cities in G, G and P. Results: As the results of hierarchical regression analysis, job embeddedness was lower when nurses had clinical experiences for 1 to under 5 years (β=-.49, p<.001), 5 to under 10 years (β=-.27, p=.035), 10 to under 20 years (β=-.54, p<.001) compared to those who had clinical experiences for more than 20 years. Also, job embeddedness was higher when there was greater balance within team caregiving of reciprocality (β=.27, p<.001) and intrinsic reward (β=.22, p=.003), and lower role conflict (β =-.27, p<.001). Conclusion: The results of the study showed that job embededness would increase if the role conflict of comprehensive nursing care unit nurses reduces, if there was a culture that the members can make cooperative relationship with other health care professionals and, if there was an appropriate intrinsic reward depending on their work experience.

건설업은 노동집약적 산업으로, 성능과 생산성의 변동성이 매우 높다. 따라서 계약자의 실제 성과를 파악하기 위해 기준생산성을 정량적이고 객관적으로 산출하여야 한다. 하지만, 기존 문헌에서 주로 제시된 기준생산성 산출 방법은 주관성이 내재된 기준을 사용하여 기준생산성을 산출한다는 한계가 있다. 또한, 데이터 수집에 과도한 비용과 시간이 투입되는 기존의 'Five-minute Rating'과 같은 데이터 수집 방식으로는 공사 현장에서 실적 물량, 실적 자원과 저해 요인이 포함된 Detailed Data를 수집하기 어렵다. 이에 본 연구에서는 Unimpacted Productivity BP를 산출할 때 활용되는 Detailed Data를 체계적인 형식으로 기록할 수 있는 작업 체크시트 와 과도한 비용과 시간을 들이지 않고 데이터를 수집하고 활용할 수 있는 프로세스를 제시하였다. 또한 기존 기준생산성 산출 방법의 객관성과 신뢰도 문제를 해결하기 위해 비교 분석하여. Detailed Data를 활용한 보다 더 객관적이고 정확한 Unimpacted Productivity BP를 활용한 기준생산성 산출을 제안한다.

Fisheries is known as a high-risk industry in Korea, and various efforts have been made to reduce occupational accidents. Trap fisheries represent crustacean production, accounting for 4.7% of total fisheries production and 10.7% of its production value, which is classified as a relatively high-risk industry. With the disaster insurance payment data of the National Federation of Fisheries Cooperatives (NFFC) from 2016 to 2020, the accident rate of the entire fishery, the accident rate of trap fisheries, and the type of disasters in the past five years were analyzed. As a result, the average fishery accident rate for the past five years was 5.31%, but it was high at 6.15% for coastal trap fisheries and 5.59% for offshore trap fisheries. Slips and trips, struck by objects and contact with machinery were the most common types of the accident according to the characteristics of the work, and hand injuries were analyzed the most. Additional efforts, including education for accident prevention, development of personal protective equipment and improvement of the working environment, are needed to prevent accidents caused by repeated types of disasters.

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.

Purpose: Overtriage and undertriage rates are critical metrics in trauma, influenced by both trauma team activation (TTA) criteria and compliance with these criteria. Analysis of undertriaged patients at a level I trauma center revealed suboptimal compliance with existing criteria. This study assessed triage patterns after implementing compliance-focused process interventions. Methods: A physician-driven, free-text alert system was modified to a nonphysician, hospital dispatcher-guided system. The latter employed dropdown menus to maximize compliance with criteria. The preintervention period included patients who presented between May 12, 2020, and December 31, 2020. The postintervention period incorporated patients who presented from May 12, 2021, through December 31, 2021. We evaluated appropriate triage, overtriage, and undertriage using the Standardized Trauma Assessment Tool. Statistical analyses were conducted with an α level of 0.05. Results: The new system was associated with improved compliance with existing TTA criteria (from 70.3% to 79.3%, P=0.023) and decreased undertriage (from 6.0% to 3.2%, P=0.002) at the expense of increasing overtriage (from 46.6% to 57.4%, P<0.001), ultimately decreasing the appropriate triage rate (from 78.4% to 74.6%, P=0.007). Conclusions: This study assessed a workflow change designed to improve compliance with TTA criteria. Improved compliance decreased undertriage to below the target threshold of 5%, albeit at the expense of increased overtriage. The decrease in appropriate triage despite compliance improvements suggests that the current criteria at this institution are not adequately tailored to optimally balance the minimization of undertriage and overtriage. This finding underscores the importance of improved compliance in evaluating the efficacy of TTA criteria.

Background: This study aims to develop an evaluator that can quickly and accurately evaluate the shielding of low-energy industrial radiation generators. Methods: We used PyQt to develop a graphical user interface (GUI)-based program and employed the calculation methodology reported in the National Council on Radiation Protection and Measurements (NCRP)-49 for shielding calculations. We gathered the necessary factors for shielding evaluation using two libraries designed for Python, pandas and NumPy, and processed them into a database. We verified the effectiveness of the proposed program by comparing the results with those from safety reports of six domestic facilities. Results: After verifying the effectiveness of the program using the NCRP-49 example, we obtained an average error rate of 1.73%. When comparing the facility safety report and results obtained using the program, we found that the error rate was between 1.09% and 6.51%. However, facilities that did not use a defined shielding methodology were underestimated by 31.82% compared with the program (the final barrier thickness satisfied the shielding standard). Conclusion: The developed program provides a fast and accurate shielding evaluation that can assist personnel that work in radiation generator facilities and government officials in reviewing safety.

Objectives: Our previously published study showed that a workplace nutrition intervention program with personalized goal setting and smartphone-based nutrition counseling improved dietary habits and physical activity in city bus drivers who were overweight/obese. This study explored the facilitators and barriers that participants faced in achieving their dietary and physical activity goals six months after the intervention. Methods: The study included bus drivers and dietitians who participated in the intervention program. Three focus group interviews were conducted with 10 bus drivers (divided by two groups based on their achievement of set goals) and five dietitians who had provided nutrition counseling. Results: Willpower was the most important intrapersonal facilitator for drivers to achieve their goals. Other factors that promoted behavioral changes were nutrition counseling by dietitians, trackable physical activity using smartwatches, and setting of practical and achievable goals. Meanwhile, the most important barriers identified were occupational factors such as long driving hours, short breaks, and shift work. Other barriers were environmental factors such as availability of snackable food, accessibility to convenience stores, and cold weather. Family and colleagues were perceived as both facilitators and barriers. In addition, dietitians identified a lack of knowledge about healthy diet as one of the barriers. Conclusions: Our results suggested that the workplace environment should be improved and that nutrition intervention programs at the workplace could encourage bus drivers to practice healthy eating habits. The facilitators and barriers identified in this study should be considered when planning a nutrition intervention program for bus drivers.
