Purpose: The purpose of this study is to predict a reasonable direction to design a pertinent educational program in the future by evaluating an adult CPR(Cardiopulmonary Resuscitation) skill performed by EMTs engaged in fire services organization and comparing the CPR success rate of factors as like a duty place and licensed year. Methods: We studied CPR skill by the use of a CPR manikin(Skillmeter Resusci Annie, Laerdal company). The study population consisted of 320 EMTs. Every EMT performed four cycle after investigating the manikin for 2 minutes. We regarded chest compression with 100 times in a minute as the 100% success rate. We analysed the skill of chest compression, ventilation and chest compression times success rate by the records printed in the CPR paper. Results: The average success rate of chest compression was 59.42$\pm$29.26% and ventilation 49.22$\pm$29.65%. The success rate of manual CPR was different between chest compression and ventilation. Also the success rate of chest compression times was high relatively as a 87.32$\pm$9.14%(p=0.000). For the CPR skill, ventilation was lowest as 49.22%. The factors such as duty place and licensed year did not influence the CPR success rate (p>0.001). Conclusion: We could have conclusion that CPR training should be shared more time in ventilation than in chest compression. Also we could reach to a conclusion that it is important to increase the times of CPR training for improving the accuracy of CPR and that the continuing education of CPR training frequency might be more than four times in a year.

In this article I tried to take an overview of the training course of Chinese Archivists. The emphasis of this work lies on the development of the Archives College of Renmin. Univ. of China after the Cultural Revolution. It includes also the development in 1950's and early '60's. An overview of the Chinese development in 1950's and early '60's will be helpful for the development of Korean archival system, especially in training of archivists. What is necessary above all in our today's situation is to bring some experiences from the advanced countries in this field. It can be carried out in two ways : the empirical studies of archival development in foreign countries and the systematic translation of their publications. It also needs an establishment of professional institutes for the archival studies in Korea. In fact the professional archivists are now hardly found in Korea. Those scholars working in the archival areas now are not archival specialists in their academic origin. Because of the urgent needs some scholars of related fields, i.e. history and library science, take over the roles of researchers and instructors in archival studies. It is therefore very urgent to offer the environment where the archivists are able to devote themselves to research in archival science. In conclusion, we need to pursue the studies of archives to give order to the records we find in the long history of our archival tradition. By doing so, we can develop our own archival science in the end. This project, however, needs supports from the government for the formation of policies, securement of budget and collaboration between the related agencies to pave a way for the strong foundation of Korean archival studies. Without these supports it might take much more time then that Chinese have taken for the enhancement of their own archival studies.

Purpose: This study aimed to identify the risk factors for diabetic foot ulceration (DFU) to develop and evaluate the performance of a DFU prediction model and nomogram among people with diabetes mellitus (DM). Methods: This unmatched case-control study was conducted with 379 adult patients (118 patients with DM and 261 controls) from four general hospitals in South Korea. Data were collected through a structured questionnaire, foot examination, and review of patients' electronic health records. Multiple logistic regression analysis was performed to build the DFU prediction model and nomogram. Further, their performance was analyzed using the Lemeshow-Hosmer test, concordance statistic (C-statistic), and sensitivity/specificity analyses in training and test samples. Results: The prediction model was based on risk factors including previous foot ulcer or amputation, peripheral vascular disease, peripheral neuropathy, current smoking, and chronic kidney disease. The calibration of the DFU nomogram was appropriate (χ² = 5.85, p = .321). The C-statistic of the DFU nomogram was .95 (95% confidence interval .93~.97) for both the training and test samples. For clinical usefulness, the sensitivity and specificity obtained were 88.5% and 85.7%, respectively at 110 points in the training sample. The performance of the nomogram was better in male patients or those having DM for more than 10 years. Conclusion: The nomogram of the DFU prediction model shows good performance, and is thereby recommended for monitoring the risk of DFU and preventing the occurrence of DFU in people with DM.

This study examined the factors that influence the use of YouTube-based home training contents by integrating and applying the technology acceptance model and health belief model. The main results are as follows. First of all, it was found that personal innovativeness had a positive (+) effect on perceived ease and perceived usefulness. Perceived susceptibility did not have a significant effect on perceived usefulness, and perceived benefit had a positive (+) effect on perceived usefulness. Finally, it was found that perceived ease had a positive (+) effect on perceived usefulness, Both perceived ease of use and perceived usefulness were found to have a positive (+) effect on continuous intention to use. This study will be meaningful in that it partially reconfirmed the possibility of integrating the technology acceptance model and the health belief model.

The purpose of this meta-analysis was to determine the efficacy of proprioceptive neuromuscular facilitation training on Gait. We included all randomized controlled trials assessing the efficacy of proprioceptive neuromuscular facilitation training on gait ability control in patients after stroke. This study was conducted according to the PRISMA guideline. CINAHL, PubMed and RISS were searched for studies published up to December 2020, and all randomized controlled trails assessing PNF intervention were included. This analysis included only randomized controlled trials. A total of 12 studies were selected from 1475 records obtained from the databases. The meta-analysis was performed using the R software. The overall intervention effect was moderate (standardized mean difference (SMD): 0.67, 95% confidence interval (CI): 0.50-0.84). Additionally, Gait rite (SMD: 0.69), 10m walking test (SMD: 0.59) had medium effect sizes. These findings indicate that PNF is an effective intervention for improving gait ability in patients stroke.

Background: To prepare for future work stoppages in the medical industry, this study aimed to identify the effects of healthcare worker strikes on the mortality rate of patients visiting the emergency department (ED) at six training hospitals in Daegu, South Korea. Methods: We used a retrospective, cross-sectional, multicenter design to analyze the medical records of patients who visited six training hospitals in Daegu (August 21-September 8, 2020). For comparison, control period 1 was set as the same period in the previous year (August 21-September 8, 2019) and control period 2 was set as July 1-19, 2020. Patient characteristics including age, sex, and time of ED visit were investigated along with mode of arrival, length of ED stay, and in-hospital mortality. The experimental and control groups were compared using t-tests, and Mann-Whitney U-test, chi-square test, and Fisher exact tests, as appropriate. Univariate logistic regression was performed to identify significant factors, followed by multivariate logistic regression analysis. Results: During the study period, 31,357 patients visited the ED, of which 7,749 belonged to the experimental group. Control periods 1 and 2 included 13,100 and 10,243 patients, respectively. No significant in-hospital mortality differences were found between strike periods; however, the results showed statistically significant differences in the length of ED stay. Conclusion: The ED resident strike did not influence the mortality rate of patients who visited the EDs of six training hospitals in Daegu. Furthermore, the number of patients admitted and the length of ED stay decreased during the strike period.

Background: With advances in safety measures for anesthesia, conscious sedation has gained popularity in the field of dentistry and has become essential in dental practice worldwide. However, in Tanzania, intravenous (IV) sedation is rarely practiced in the dental field. Therefore, we report the establishment of sustainable IV conscious sedation in dental practices and subsequently train local OMS residents in Tanzania. Methods: In 2019, intravenous conscious sedation was initiated at the University Dental Clinic of the Muhimbili University of Health and Allied Science (MUHAS), Tanzania. During the preparatory phase of the program, local oral and maxillofacial surgeons (OMSs) were given a series of lecture notes that concentrated on different aspects of IV conscious sedation in dentistry. During the on-site training phase, an oral surgeon from the United States joined the OMSs for case selection, IV-conscious sedation procedures, and patient follow-up. Patients were recruited from existing patient records at the MUHAS Dental Clinic. Results: The first conscious IV sedation program in dentistry was successfully launched at the University Dental Clinic in Tanzania. The local team of OMSs was trained on the safe administration of sedative agents (midazolam or ketamine) to perform various minor surgical procedures in a dental office. Nine patients with different ages, body masses, and medical conditions benefited from the training. No complications were associated with IV conscious sedation in the dental office. Conclusion: This was the first successful "hands-on" training on IV conscious sedation provided to OMSs in Tanzania. It laid the foundation for the sustainable care of patients with special needs requiring oral health-related care in the country.

Asset prices decline sharply and stock markets collapse when financial crisis happens. Recently we have encountered more frequent financial crises than ever. 1998 currency crisis and 2008 global financial crisis triggered academic researches on early warning systems that aim to detect the symptom of financial crisis in advance. This study proposes a risk recovery index for detection of good opportunities from financial market instability. We use SVM classifier algorithms to separate recovery period from unstable financial market data. Input variables are KOSPI index and V-KOSPI200 index. Our SVM algorithms show highly accurate forecasting results on testing data as well as training data. Risk recovery index is derived from our SVM-trained outputs. We develop a trading system that utilizes the suggested risk recovery index. The trading result records very high profit, that is, its annual return runs to 121%.

Maritime safety is influenced by several factors, for example, technical factors, human factors and operational factors. To improve maritime safety, each country should identify which factors will bring about a marine accident. This case study approached statistical method to find out correlations between marine accidents and safety records in Korean merchant fleet. There were no statistical significance between marine accident rate and PSC detention rate and human factor rate. But there was statistically significant relationship between marine accident rate and PSC inspection rate. It is possible to presume that in the developing country the stronger the government shows its will, the less such accidents occur.
