The purpose of this study is to identify the subjective health status, COVID-19 risk perception, antibody knowledge, social influence, intention of acceptance of the COVID-19 antibody test for general adults and the factors affecting the acceptance of the COVID-19 antibody test. The subjects of the study were 147 adults, and the collected data were analyzed using the SPSS 27.0 program using the frequency, percentage, average and standard deviation, independent t-test, ANOVA, pearson's correlation coefficients, and multiple regression analysis. The results, the acceptance of the COVID-19 antibody test has a significant static correlation with the social influence, the COVID-19 risk perception, and the negative correlation with the subjective health. The factor affecting the acceptance of the COVID-19 antibody test of the general adult was a social influence, and their explanatory power was 50.2%. As a result of this study, COVID-19 antibody tests may be used by preparing effective measures to prevent the spread of the COVID-19 infection.

The purpose of this study is to derive the optimal methodology estimating the changes of fluvial hydraulic characteristics due to semi-covering work of urban stream. First, after collecting the data of the daily maximum rainfall of Chungju gaging station, the frequency analysis was carried out with frequency factor method, which includes normal, two-parameter and three-parameter lognormal, Gumbel-Chow, pearson type III, log-pearson type III distribution, and the goodness of fit test was executed by $x^2$-test and Kormogorov-Smimov test. Using the SCS method, the effective rainfall was estimated and the peak flow was calculated by the area-routing method. The HEC-2 model was applied to calculate water surface profiles for steady, gradually varied flow at Kyohyun river system in Chungju city. The model was applied to floodplain and riverbed management to evaluate flood way encroachments and to delineate flood hazard by riverside roadway construction. The model also was used to evaluate effects on water surface profiles of river improvement and levees as well as the presence of bridges or other hydraulic structures in the floodplain.

Purpose: The purpose of this study was to compare nursing students before using problem-based learning and after the experience in: class satisfaction, tendency to critical thinking, learning attitude and motivation. Method: The data were collected on March 20 and June 5, 2008. The PBL study was given for 15 weeks from March through June involving 216 junior nursing students. To test effects of PBL, a one group pretest-posttest design was used. Statistical analysis was performed with SPSS 13.0. Paired t-test, $x^2$-test, and Pearson correlation coefficient were performed. Results: The results are summarized as follows: Following PBL, the students scored significantly higher on the class satisfaction (t=-3.321, p= .001), tendency to critical thinking (t=-2.218, p= .034), learning attitude (t=-2.910, p= .004) and motivation (t=-4.407, p<.001). The Pearson correlation coefficients among the three variables were significantly positive. Conclusion: This study contributes to our understanding of outcomes from the PBL approach. The students undertaking PBL showed that they developed a more positive attitude with their educational experience. Also, students' tendency to think critically improved through the use of the PBL approach.

The Study was conducted to understand the degree of knowledge, awareness and performance of nursing students' patients' personal information protection and to grasp the relationship between them. A convenience sample 262 nursing students was selected from C do, between 1 November and 8 November 2019. Using SPSS Program t-test, one-way ANOVA, Pearson's correlation analysis were performed. Factors that influenced knowledge, awareness and performance included grade, education of information. It is necessary to develop and test programs to ensure an improvement in knowledge and awareness among nursing students to increase their performance.

Although there exist numerous measures of association, most of them are lacking in generality in that they do not intend to measure the association between heterogeneous type of random variables. On the other hand, many statistical analyzes dealing with complex data sets require a very sophisticate measure of association. In this note, the p-value of independence tests is utilized to obtain a measure of association. The proposed measure of association have some consistency in measuring association between various types of random variables.

Between March and October 2007, a total of 516 blood samples from pigs in the Gyeonggi province were examined for seroprevalence against toxoplasmosis by latex agglutination test (LAT) and the detection of antigenic particles among seropositive samples by PCR. In the LAT, 118 (22.8%) were positive, and the unadjusted percentage of seroprevalence rates of breeding and fattening pigs were significant difference. Positive rate (14.1%) in the breeding pigs was much lower than that (27.8%) of the fattening pigs (p<0.001, Pearson's Chi-square test). The antibody detection rate of sows was lower than fattening pigs, i.e., 15.8% (25/158) and 26% (93/358), respectively (P=0.011, Pearson's Chi-square test). Among 118 seropositive samples by LAT, 68 (57.6%) were positive in PCR for the detection of the toxoplasma specific-DNA. There was a statistical difference in the positive PCR reaction between the raising pigs(63/93 67.7%) and sows (5/25, 20%) (P<0.01).

The purpose of the study was to investigate the influencing factors of autonomy preference on decision-making among chronic disease patients. Data were collected from 522 chronic disease patient and it was analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple linear regression, using SPSS 26.0 ver. program. Significant factor influencing decision-making preference was health concern (β=-.17, p<.001), and factors influencing information-seeking preference were gender (β=-.20, p<.001) and number of questions during the treatment (β=.09, p=.030). Healthcare providers should take into account the characteristics of patients and establishment of a strategy to improve the quality of communication.

The purpose of this study was to identify the mediating effect of resilience in the relationship between stigma and quality of life (QOL) in lung cancer patients. Participants were 119 lung cancer patients who visited the outpatient department of a hospital. The subjects completed a questionnaire of stigma, resilience and QOL. Data were analyzed using t-test, ANOVA, Scheffe test, Pearson correlation, three-step regressions to test mediating effect and Sobel test. Stigma was negatively correlated with resilience and QOL. Resilience was positively correlated with QOL. Stigma explained 15.0% of the variance of resilience. Stigma and resilience explained 41.0% of the variance of QOL. Resilience had a partial mediating effect in the relationship between stigma and QOL. The results suggest that a nursing intervention to decrease stigma and enhance resilience is recommended to improve QOL in lung cancer patients.

The purpose of this study was to identify the mediating effect of organizational citizenship behavior in relation between incivility and professional quality of life. The data collected from June 8, 2018 to June 29, 2018, and the questionnaire from 250 nurses at 3 general hospital in D city. The data were analyzed by t-test, ANOVA, Scheffe's test, Pearson's correlation, hierarchical analysis and Sobel test. Organizational citizenship behavior showed perfect mediating effect in the relationship between incivility experienced by nurses and compassion satisfaction, and partial mediating effect in the relationship between incivility experienced by nurses and burnout. The results indicate that it is necessary to develop strategies and applications to enhance organizational citizenship behavior for improved professional quality of life of a nurses who experience incivility.
