PURPOSE: Focusing on the factors that influence the infectious disease emergency response policy (approached by dividing the factors into health policy management and economic policies), both SARS and MERS cases were based on the legal system, manpower, and budget, but there has not been enough learning from the epidemic. This study focused on infectious disease emergency governance, which various studies have neglected despite its social and academic importance. METHODS: The research is based on an analysis of SARS, MERS, and COVID-19 and compares global policies. In this study, infectious disease emergency governance was divided into health policy management and economic factors. This study focused on planning and leadership before and after the outbreak of infectious diseases and how cooperation was achieved to monitor and respond to infectious diseases successfully. RESULTS and CONCLUSION: The limit of this study was that COVID-19 is a currently ongoing infectious disease with high uncertainty. Because it is an ongoing problem, only some data and statistics are reflected, and many limitations prevent a proper comparison under the same criteria as other infectious diseases. In addition, because continuous changes are expected, there is also room for infectious diseases to develop in a completely different pattern from the current situation, and continuous research must be accompanied in the future.

Purpose: This study was conducted to examine the effects of uncertainty, social support, and sick role behavior on health-related quality of life in patients with peripheral arterial disease. Methods: This study is a descriptive research using self-reporting questionnaire. Data were collected from 167 patients with peripheral arterial disease. Measurement tools were Multidimensional Scale of Perceived Social Support(MSPSS), Mishel's Uncertainty in Illness Scale (MUIS), Sick role behavior measurement tools and SF-36 Version I. The data were analyzed using descriptive statistics, correlation, and regression analysis by using SPSS/WIN 24.0. Results: Factors that significantly influenced physical health-related quality of life were age (β=-.19, p=.010), monthly income (β=.17, p=.027), uncertainty (β=-.29, p<.001), and exercise and rest (β=.28, p<.001) that all together accounted for 32.6% of the variance. Factors that significantly influenced mental health-related quality of life were monthly income (β=.20, p=.015), drinking (β=.17, p=.040), uncertainty (β=-.24, p=.001), and exercise and rest in sick role behavior (β=.26, p=.003) that all together accounted for 18.2% of the variance. Social support was an insignificant factor on physical and mental health-related quality of life. Conclusion: To improve the health-related quality of life of people with peripheral arterial disease, it is necessary to develop a systematic nursing intervention program including a strong support system, education, strategies for alcohol abstinence, and exercise and rest therapy.

Purpose: The purpose of this study was to identify the factors affecting tuberculosis prevention behaviors in North Korean adolescent refugees. Methods: From September 16 to October 8, 2019, a survey was conducted to collect data from 143 North Korean adolescent refugees aged 13 to <25 at alternative and general schools in Seoul and Gyeonggi Province. The scale developed by Park (2008) and adapted by Cha (2012) was used to rate tuberculosis prevention behaviors in daily life with the aim of preventing high school students from getting infected with tuberculosis. The collected data were processed through frequency analysis, descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple linear regression, using SPSS 25.0. Results: The mean score was 13.65 for knowledge of tuberculosis, 44.23 for attitudes towards tuberculosis, and 41.33 for tuberculosis prevention behaviors. Significant differences were found according to gender, country of origin, duration of stay in South Korea, tuberculosis examination, pre-entry chest x-ray, education about tuberculosis, alcohol intake, and subjective health status. A positive correlation was found between knowledge, attitudes, and prevention behaviors. The factors affecting tuberculosis prevention behaviors were attitudes (β=.38, p<001) and subjective health status (β=.26, p<.001). Conclusion: It is necessary to provide attitude-based education that can reinforce positive attitudes in order to improve North Korean adolescent refugees' tuberculosis prevention behaviors. This is expected to help them pay more attention to health care and become better at prevention behaviors. It is, therefore, necessary to develop a tuberculosis prevention education program with the aim of making them more knowledgeable about tuberculosis and providing them with systematic and sustainable education.

Objective: The aim of this study was to evaluate the correlation between the vertical position of maxillary first molar and vertical skeletal measurements in lateral cephalograms by using new linear measurements on the vertical axis of coordinates with calibration. Methods: The vertical position of maxillary first molar (U6-SN), and the conventionally used variables (ConV) and the newly derived linear variables (NwLin) for vertical skeletal patterns were measured in the lateral cephalograms of 103 Korean adults with normal occlusions. Pearson correlation analyses and multiple linear regression analyses were performed with and without calibration using the anterior and posterior cranial base (ACB and PCB, respectively) lengths to identify variables related to U6-SN. Results: The PCB-calibrated statistics showed the best power of explanation. ConV indicating skeletal hyperdivergency was significantly correlated with U6-SN. Six NwLin regarding the position of palatal plane were positively correlated with U6-SN. Each multiple linear regression analysis generated a two-variable model: sella and nasion to palatal plane. Among the three models, the PCB-calibrated model yielded highest adjusted R2 value, 0.880. Conclusions: U6-SN could be determined by the vertical position of the maxilla, which could then be used to plan the amount of molar intrusion and estimate its clinical stability. Cephalometric calibration on the vertical axis of coordinates by using PCB for vertical linear measurements could strengthen the analysis itself.

Purpose: This study examined the relationship between Knowledge of Life-sustaining Treatment Plans and Attitudes toward Withdrawal of Life-sustaining Treatment among nursing college students, and attempted to identify the mediating effect of Role Perception on Life-sustaining Treatment in that relationship. It is hoped that the findings will ultimately contribute to the development of active nursing strategies. Methods: The participants were 142 nursing college students in the third and fourth years of study who had experienced clinical practice at two universities in cities Y and C. Data were collected from November 1 to 30, 2019. For data analysis, SPSS for Windows version 22.0 was used to calculate descriptive statistics, the t-test, Pearson's correlation coefficients, and multiple regression. To analyze the mediating effect, the Baron and Kenny bootstrapping method was used. Results: Attitudes toward Withdrawal of Life-sustaining Treatment of nursing college students had a significant positive correlation with Knowledge of Life-sustaining Treatment Plans (r=0.34, P<0.001) and Role Perception on Life-sustaining Treatment (r=0.44, P<0.001). Role Perception on Life-sustaining Treatment partially mediated the relationship between Knowledge of Life-sustaining Treatment Plans and Attitudes toward Withdrawal of Life-sustaining Treatment (95% CI, 0.446~1.055). Conclusion: Based on the results of this study, improving nursing college students' Role Perception on Life-sustaining Treatment could be used as a coping strategy to establish positive Attitudes toward Withdrawal of Life-sustaining Treatment.

Purpose: The purpose of this study is to identify the effects of organizational commitment (OC) and perceived patient safety culture (PPSC) on patient safety nursing activities (PSNA) among nurses in comprehensive nursing care units. Methods: Participants were 173 nurses working at five general hospitals in Chungcheong area. Data were analyzed using descriptive statistics, 𝑥² test, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis with SPSS/WIN 23.0 programs. Results: The mean scores of the OC and PPSC were 3.28±0.50 and 3.85±0.35, respectively. The mean score of PSNA was 4.55±0.41, and PSNA was significantly different by the experience of participating in hospital's safety culture campaigns (t=2.70, p=.008). The results of the multiple regression analysis showed that 'patient safety knowledge and attitudes' (β=.27, p=.006) and 'unpunished environment to error' (β=.22, p=.004) as the sub-categories of PPSC were affecting factors on PSNA with an explanatory power of 26.0% (F=6.40, p<.001). Conclusion: The results of this study suggest that in order to promote PSNA among nurses in comprehensive nursing care units, it is necessary to develop a program to enhance patient safety-related knowledge and attitudes. In addition, the hospital's organizational efforts such as operating safety campaigns and creating an unpunished environment to error should be needed.

Purpose: This study was conducted to investigate the nursing needs and workload of nurses according to nursing dependency for effective placement of nursing staff in the emergency department (ED). Methods: In June 2020, 256 adult patients who visited the ED were classified as two groups, suspected COVID-19 patients and general patients. The participants'electronic medical records were analyzed using descriptive statistics, t-test, 𝑥²-test, and Fisher's exact test using the SPSS. Results: The patient dependence score showed a significant difference between the two groups, with an average of 13.99±1.85 for the suspected COVID-19 patient group and 10.58±2.10 for the general patient group (t=12.42, p<.001). There were statistically significant differences in communication (t=3.28, p=.001), mobility (t=3.29, p=.001), nutrition, elimination, and personal care (t=7.34, p<.001) among the six domains of nursing dependency. In the domains of environment, safety, health, and social needs, the dependency score was 3 for all suspected COVID-19 patients and 1 for all general patients. Conclusion: The results of this study confirmed that infection control activities of emergency patients who need isolation affect the patients' nursing dependency on nursing care.

Purpose : This study aimed to identify the status of intrahospital transport (IHT) of critically ill patients and provide baseline data to form recommendations for safer transport. Methods : Data were collected from 141 intensive care unit (ICU) nurses who attended national conferences between February and August, 2018. The collected data were analyzed using descriptive statistics and ANOVA, and post-hoc analysis was conducted with the Scheffé and Games-Howell tests. Results : Of the nurses surveyed, 61.7% answered that their workplace had a transport guideline. In terms of the experience of ICU nurses, 31.2% of respondents answered that they had received training on IHT. This result indicated that the degree of implementation of the guidelines for IHT was generally high, but some, including guidelines on personnel, equipment, and monitoring, were not. Guidelines of IHT were well observed when the institutes had specific guidelines for IHT of critically ill patients with specified transport grades, a scoring system to assess stability of a patient, a checklist and a protocol for action in case of problems, and when healthcare providers were provided with training. Conclusion : These results suggest that organized infrastructure, such as a transport guideline with transport grades, a checklist to improve the implementation of guidelines, and a protocol for coping with a problem, should be provided for safe transport. Additionally, effective education and evaluation to improve the competency of staff participating in the transport of patients will help reduce the occurrence of adverse events in intensive care transport in hospitals and promote patient safety.

Background: The purpose of this study is to investigate the effect of muscle energy technique and stretching on pain and pressure pain fear-avoidance beliefs questionnaire in patients with chronic back pain aged 30~40 years. Design: Pretest-Posttest design: single blind. Methods: The subjects of this study were 30, 22 males and 8 females between the ages of 30 and 40 with chronic back pain. Each group consists of three groups of 10 people. Changes in back pain were observed using Korean version of Oswestry Disability Index (K-ODI), visual analogue scale (VAS), and fear-avoidance beliefs questionnaire (FABQ). And the change in tenderness was observed using digital pressure statistics. Changes between groups after 3 weeks were compared with those before the experiment using one way ANOVA to determine the changes after 3 weeks. And the change within the group was investigated using the paired t-test. Results: As a result of the experiment, there were significant differences in the group changes in K-ODI, VAS, FABQ, and pressure pain (p<0.05). And there was a significant difference in all items after 3 weeks compared to before the experiment (p<0.05). Conclusion: In patients with chronic back pain, the muscle energy technique and stretching gave a significant difference in pain and pressure pain, fear-avoidance beliefs questionnaire changes. And this result suggests the possibility of providing basic data for future research and clinical physiotherapy intervention.

Purpose: This study investigates the effect of repeated use of lithium disilicate glass-ceramics on color stability. Methods: In this study, 2 types of lithium disilicate glass-ceramics were used and they were divided into 4 groups after 1st, 2nd, 3rd, and 4th heat pressing. The L^*, a^*, and b^* values of all specimens were measured using the VITA Easyshade Advance 4.0. These values was used to determine the ∆E value and transparency. IBM SPSS Statistics ver. 24.0, a statistical significance level of 0.05 and one-way ANOVA were used for all data. Results: In all groups, the L^* and b^* values were the lowest in the specimens subjected to the 4th heat pressing and the corresponding a^* value was the highest. All specimens showed ∆E values of ≤3.3, indicating color changes that were not visible with the naked eye, and the color difference increased with the number of repeated heat pressing. The transparency of all specimens decreased as the number of repeated uses increased. Conclusion: According to the number of repeated heat pressing, the color difference of Rosetta SP (HASSBIO) was larger than that of IPS e.max Press (Ivoclar Vivadent), but it was clinically acceptable in all groups. Moreover, transparency decreased as the number of heat presses increased in all groups. According to the above findings, the lithium disilicate glass-ceramic has high color stability due to repeated heat pressing, implying that it can be used in clinical settings regularly.
