Purpose: This study aimed to identify factors affecting the quality of life of the elderly people with chronic musculoskeletal pain. Methods: The data were collected from 307 older adults aged 65 years or older with chronic musculoskeletal pain, who visited senior welfare centers in two cities. We used self-rated questionnaires including NRS for pain, WHOQOL-BREF for quality of life, Pain Response Inventory for coping responses to pain, and MSPSS for social support. Stepwise multiple regression analysis were performed using SPSS/WIN 23.0 to identify factors affecting the study subjects' quality of life. Results: The regression model explained 43% of quality of life, which was statistically significant (F=34.11, p<.001). Educational level of high school (${\beta}=.13$, p=.006), pain (${\beta}=-.13$, p=.013), restriction of function (${\beta}=-.13$, p=.028), accommodative pain coping (${\beta}=.24$, p<.001), family support (${\beta}=.18$, p<.001), colleague's support (${\beta}=.25$, p<.001), and perceived health status (${\beta}=.25$, p<.001) were identified as influential factors on subjects' quality of life. Conclusion: Developing integrative interventions is necessary to improve accommodative pain coping skills and to engage family and colleague in support for positive perception of older adults' health status and management of symptoms.

Purpose: This study investigated the statistical methods and the results had reported correlation/regression analysis in the studies of Korean Journal of Women Health Nursing (KJWHN). Methods: We reviewed 45 studies using correlation/regression analysis for the suitability of the statistical methods and the research purposes, the criteria for analysis of figures, tables and charts had published in the KJWHN from vol 13 (1) in 2007 to vol 15 (4) in 2009. Results: Forty three studies were fitted to their statistical methodology and their research purposes. Eleven studies considered the minimum sample size. Fourteen regression studies used multiple regression and 12 studies used forward method for variable entry. Only one study among the 17 regression studies accomplished scatter plots and residuals examination. Sixteen studies in correlation studies and six studies in regression studies showed some errors in either the title, variables, category of figures, tables and charts. In the regression study, all reported $R^2$ and ${\beta}$ values except one. Conclusion: It was found that there were still statistical errors or articulation errors in the statistical analysis. All reviewers need to be reviewed more closely for detecting errors not only during reviewing process of the manuscript but also periodic publication for the quality of this academic journal.

The purpose of this research was to analyze the relationship between human risk factors and evacuation behavior stages for tunnel safety. Therefore, we conducted a survey using a structured questionnaire on the relationship between safety facilities and safety behavior in order to derive an optimized interaction between the two. The research subjects were 141 tunnel users who understand the tunnel environment. The survey period was from June 24, 2018, to September 28, 2018. As data analysis methods, we employed a frequency analysis, a multiple regression analysis, and an independent-sample t-test. In the analysis of the correlation between the human risk factors and the major variables of evacuation behavior, the evacuation phases 1, 2, and 3 were all correlated with acceleration and delay, and the human risk factors were partially correlated. In the multiple regression analysis, the will to comply with laws (${\beta}=0.188$, p=0.034) and information recognition within the tunnel (${\beta}=0.220$, p=0.009) were factors that influence the relationship between human risk factors and evacuation behavior, indicating 12% explanatory power of the impact of human risk factors for the acceleration of evacuation behavior 3. The important variables between human risk factors and evacuation behavior were compliance with laws and information recognition in tunnels. Hence, it is necessary to study the elements that interact with the environment in the tunnel.

Purpose: The purpose of this study was to evaluate food carving among hemodialysis patients and to identify factors affecting the food carving. Methods: A descriptive correlational study was conducted. Data were collected from 129 patients receiving hemodialysis between March 15 and April 15, 2017. Measurement instruments included the general food craving questionnaire trait, the center for epidemiological studies-depression scale, and stress response inventory-modified form. The statistical analysis included t-test, analysis of variance, pearson correlation analysis, and stepwise multiple regression analysis. Results: Mean food craving score was $53.00{\pm}12.36$. Food craving was higher in patients younger than 40 years (F=4.36 p=.006) and having occupation (t=2.18 p=.031). Patients receiving hemodialysis demonstrated higher levels of depression ($21.37{\pm}9.62$) and stress ($39.68{\pm}15.95$). Factors influencing food craving were depression (${\beta}=.52$, p<.001), stress (${\beta}=.65$, p<.001), and age 50~59 years old (${\beta}=-.28$, p=.001) and 60~69 years old (${\beta}=-.19$, p=.026), which accounted for 25.6% of total variance. Conclusion: Food craving among hemodialysis patients was influenced by patients' depression, stress and age. Assessment and management of depression and stress needs to be incorporated as a nursing strategy for dietary management for hemodialysis patients.

Objectives: To investigate whether medical institutions can prevent accidents by analyzing the root cause of a medical accident and identifying the tendencies. Methods: A total of 345 medical cases were used for the RCA(Root Cause Analysis). The root causes were classified using the SHELL model. The suitability of the model was confirmed by SPSS's MDPREF and Euclidean distance. An SPSS20.0 hierarchical regression analysis was used as an influencing factor on the degree of injury resulting from medical accidents. Results: The SHELL model was suitable for classification. The rates of accident causes were LS49%, L34%, LL10.2%, LE3.7%, LH2.3%. The order in which the degree of a patient's injury was affected were: Risk Threshold (${\beta}=.180$), Time (${\beta}=.175$), Surgical stage (${\beta}=-.166$), Do not use procedure (${\beta}=.147$). Conclusions: Health care institutions should remove priorities through system improvement and training. For patients' safety, the five factors of the SHELL model should be managed in harmony.

This study examined how empowerment of restaurant cooks influences job satisfaction, organizational commitment, and customer orientation, targeting 260 restaurant cooks in the Busan area. SPSS 18.0 was employed to perform frequency, factor, reliability, and multiple (simple) regression analyses. Empowerment was analyzed using 3 factors (self-authority, meaning and competence) while job satisfaction, organizational commitment, and customer orientation were analyzed using 1 factor each. Results of a correlation analysis of the hypothesized model revealed positive correlations among the variables. Multiple (simple) regression analyses of the hypothesized model found that the sub empowerment factors will have a positive influence on job satisfaction with self-authority (${\beta}$=.372, p<.001), meaning (${\beta}$=.451, p<.001), competence (${\beta}$=.240, p<.001). It was also found that the sub empowerment factors will have a positive influence on organizational commitment with self-authority (${\beta}$=.433, p<.001), meaning (${\beta}$=.473, p<.001), competence (${\beta}$=.302, p<.001). Lastly, the hypotheses that job satisfaction will have a positive influence on organizational commitment (${\beta}$=.775, p<.001), that job satisfaction will have a positive influence on customer orientation (${\beta}$=.467, p<.001), and that organizational commitment will have a positive influence on customer orientation (${\beta}$=.567, p<.001) were adopted.

This study examined the effects of interpersonal relationship harmony and stress coping on the college adjustment among nursing students. The participants were 231. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression. Adjustment to college life significantly correlated with interpersonal relationship harmony and stress coping style. Interpersonal relationship harmony was significantly different according to year, satisfaction with nursing as a major, and academic achievement. Multiple regression analysis showed that interpersonal relationship harmony and stress coping(problem-focused, emotion-focused, hopeful thought) explained 23% of variance in adjustment to college life. The study findings suggest that intervention intended to promote nursing students' adjustment to college life should focus on improving interpersonal relationship harmony and stress coping.

Purpose: The purpose of this research was to delineate the effects of organizational injustice on negative behaviors of employees with the mediating effects of trust. Methods: A survey was conducted among 550 nurses in 11 departments of 3 hospitals located in the Pohang area. Data were analyzed using frequency, descriptive statistics. correlation coefficients, regression analysis. Results: Procedural injustice (${\beta}$=-.48, p<.001) had the greatest negative effect on organizational trust, followed by interactional injustice(${\beta}$=-.15, p<.001) and distributive injustice(${\beta}$=-.14, p<.001). For supervisor trust, both procedural (${\beta}$=-.11, p=.006) and interactional (${\beta}$=-.63, p<.001) injustice had a negative effect. While supervisor trust (${\beta}$=-.28, p<.001) had greater negative effects on organizational negative behaviors of nurses compared to organizational trust (${\beta}$=-.21, p<.001), supervisor trust (${\beta}$=-.29, p<.001) had negative effects on personal negative behaviors but organizational trust had no significant effect on personal negative behaviors. Conclusion: To reduce the negative organizational behaviors of nurses, an organizational effort is needed to reduce procedural injustice by introducing fair organizational management and to reduce interactional injustice through formal or informal communication channels between supervisors and nurses.
