  • An accurate fire danger rating model can contribute to effective forest fire prevention activities. This study evaluates the national forest fire danger rating index based on forest fire statistics data from 1999 to 2002. The number of fires was related to the forest fire danger rating index $(R^2=0.67)$, and no correlation was found with burned areas. A one-way ANOVA test between forest fire danger rating levels and forest fire statistics data indicated that a difference in the number of fires was found among 'danger', 'precaution' and 'none' levels, but 'precaution' and 'none' levels could not be delineated. In the case of a burned area, no difference was found among the three levels.

  • The purpose of this study was to identify the factors affecting the life satisfaction of the mentally ill people in mental care facilities. The data were collected by a self-reported questionnaire form 215 mentally ill people in mental care facilities from July 1 to 28, 2014. The instruments for this study were depression, self-esteem, social support, insight and life satisfaction. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and hierarchial multiple linear regression with the SPSS/WIN 18.0 program. According to results, the significant factors influencing life satisfaction were social support (${\beta}=.518$, p=.000), go out (${\beta}=.155$, p=.001), self-esteem (${\beta}=.155$, p=.013), depression (${\beta}=-.147$, p=.015), gender (${\beta}=-.125$, p=.011). The study reveals that it is necessary to develop a program that increases social support and self-esteem and decreases depression.

  • The purpose of this research is to identify the level of perception of conflict with politics within nursing organizations in large general hospitals, and to empirically analyze how politics and conflicts in the organization affect workplace bullying(taeoom) within nursing organizations. The research method conducted multiple regression analysis on 273 nurses working at A University Hospital in Seoul. The analysis shows that political and relationship conflicts within the organization are amplifying the workplace bullying within the nursing system. It was confirmed that taeoom was also increasing as conflicts between factions or subgroups within the nursing system, alienation, and emotional conflicts among members grew. We hope that the future research regarding taeoom will seek serious theoretical insights and practical implications for its management.

  • This study aims to propose a prediction model for the drape coefficient using artificial neural networks and to analyze the nonlinear relationship between the drape properties and physical properties of fabrics. The study validates the significance of each factor affecting the fabric drape through multiple linear regression analysis with a sample size of 573. The analysis constructs a model with an adjusted R2 of 77.6%. Seven main factors affect the drape coefficient: Grammage, extruded length values for warp and weft (mwarp, mweft), coefficients of quadratic terms in the tensile-force quadratic graph in the warp, weft, and bias directions (cwarp, cweft, cbias), and force required for 1% tension in the warp direction (fwarp). Finally, an artificial neural network was created using seven selected factors. The performance was examined by increasing the number of hidden neurons, and the most suitable number of hidden neurons was found to be 8. The mean squared error was .052, and the correlation coefficient was .863, confirming a satisfactory model. The developed artificial neural network model can be used for engineering and high-quality clothing design. It is expected to provide essential data for clothing appearance, such as the fabric drape.

  • This study investigates whether foreign equity ownership is associated with trading volume. This study establishes null hypothesis indicating that foreign equity ownership is not related to trading volume based on prior studies regarding foreign equity ownership. We measured trading volume as proxy of investors' heterogeneous beliefs. To exam The the hypothesis, we collected sample firms listed on the Korean Stock Exchange from the year of 2001 to the year of 2011 inclusively. Controlling for variables related with trading volume as reported in the previous studies, the regression coefficient for the foreign equity ownership showed statistically significant negative sign. These results indicate that the foreign equity ownership is negatively associated with investors' heterogeneous beliefs. This study contributes to extant literature on foreign equity ownership by providing evidence that foreign equity ownership affects investors' trading decisions. The results also help policy makers in their policy development.

  • This exploratory study aims to identify effect on core nursing competency of nursing students who experienced convergence practice due to COVID-19. The subjects of this study surveyed 123 senior nursing students in U city with a structured self-report questionnaire analyzed by the SPSS 22.0 software, t-test, One-way ANOVA, correlation, and multiple regression analysis. The average scores for nursing competence scale, self-directed learning ability, learning satisfaction, learning outcomes were 3.99, 3.71, 4.11 and 4.25 out of 5.00. The factors affecting of students' nursing competencies were self-directed learning ability, learning outcomes with 29 percent being explained by these variables. Learning satisfaction did not affect core nursing competency. Through this study we found that high quality educational environment should be prepared to improve these limitations. it is considered that a clear and systematic standard for the educational environment and evaluation of clinical practice is needed.

  • This study causally investigates whether high school student with high science learning motivation becomes to achieve more or vice versa, and also how those two factors affect STEM career motivation. Research participants were 1st year students in a high school at Seoul. We surveyed their science learning motivation three times in the same time interval in the fall semester of 2021, and once a STEM career motivation in the third period. We collected data from 171 students with their mid-term and final exam scores, with which, we constructed and fitted an autoregressive cross-lagged model. The research model shows high measurement stability and fit indices. All the autoregressive and cross-lagged paths were statistically significant. However, standardized regression coefficients were larger in path from motivation to achievement compared to the opposite. Only science learning motivation shows significant direct effect on STEM career motivation, rather than achievement. For indirect effects, the first science learning motivation affected the final exam score and STEM career motivation, and the final exam score affected STEM career motivation. However, the final exam score did not have a total effect toward STEM career motivation. The result of this study shows reciprocal and cyclic causality between science learning motivation and achievement - in comparison, the effect of motivation for the opposite is larger than that of achievement. Also the result of this study strongly reaffirms the importance of science learning motivation. Instructional implications for strengthening science learning motivation throughout a semester was discussed, and a study for the longitudinal effect of science learning motivation and achievement in high school student toward future STEM vocational life was suggested.
