  • PURPOSE: A gait assessment is an important component of the rehabilitation process, and observational gait assessment (OGA) is used routinely in clinical settings. This study examined the association of OGA tools with the independent walking ability in stroke patients to determine a cutoff value of the OGA tool according to independence levels of stroke patient gait. METHODS: Two hundred ten hemiparetic stroke patients participated in the study. The independence of gait was identified using the Functional Ambulation Category (FAC) classifications. The walking ability was assessed using OGA tools (Rivermead Visual Gait Assessment [RVGA], Wisconsin Gait Scale [WGS], Tinetti Gait Scale [TGS], and Functional Gait Analysis [FGA]). RESULTS: Stepwise multiple regression analysis showed that among the OGA tools, the FGA correlated with the FAC. The FGA explained approximately 77% of the variance in FAC. In distinguishing the independence levels, the cutoff values were as follows: between FAC 1 and FAC 0 was .5 points; between FAC 2 and lower levels, 5.5; between FAC 3 and lower levels, 11.5; between FAC 4 and lower levels, 14.5; and between FAC 5 and lower levels, 18.5. Items 1, 2, 3, and 10 were identified as explaining most of the variance in the FGA in the stepwise multiple regression. CONCLUSION: The present study found that the FGA is an assessment tool related to the level of gait independence after stroke. Furthermore, the FGA total score can serve as an index of the increase in independence level after stroke.

  • Purpose: This descriptive cross-sectional study aimed to examine the influence of nurses' moral sensitivity and ethical values on their biomedical ethics awareness. Methods: The study participants included 140 registered nurses working at three hospitals in Jeollabuk-do Province over six months. The data were collected from June 22 to July 3, 2020, and were analyzed using descriptive statistics, an independent t-test, one-way ANOVA, Pearson correlation coefficients, and stepwise multiple regression analysis with the IBM SPSS/WIN 20.0 program. Results: As a result of an analysis using stepwise multiple regression, nurses' biomedical ethics awareness was found to be significantly influenced by ethical values (β=.36, p<.001), moral sensitivity (β=.21, p=.007), and education in biomedical ethics (β=.16, p=.042) (adjusted R2=.21, p<.001). Conclusion: These findings suggest that moral sensitivity and ethical values are key factors in hospital nurses' development of biomedical ethics. Furthermore, the devising and implementing of a practical education program based on practical cases in medical situations to enhance nurses' biomedical ethics awareness is needed.

  • Purpose: The purpose of this study was to identify the impacts of professional socialization perceived by nursing students on role conflict and professional self-concept. Methods: Using a structured questionnaire, data were collected from 683 nursing students. For data analysis, descriptive statistics, Pearson correlation coefficient, stepwise multiple regression were conducted using SAS program. Results: The mean score of total professional socialization was 3.74 followed by the scores of 'independence', 3.98, 'commitment', 3.80, 'decision making', 3.60, and 'maturity', 3.53. The mean score of total role conflict was 3.72, and professional self-concept was 2.75. Total professional socialization, commitment, and independence perceived by nursing students were positively related to role conflict. Also total professional socialization and total subcategories of professional socialization were positively related to professional self-concept. As a result of stepwise multiple regression analysis, the key determinants of role conflict were found to be 'independence', 'motivation with admission', 'sex', 'desire with working', 'grade' and 'decision making'. The key determinants of professional self-concept were 'decision making', 'commitment', 'satisfaction about nursing', and 'interpersonal relationship'. Conclusion: Through this results, it is necessary to improve professional socialization in order to increase professional self-concept among nursing students.

  • In order to enhance sustainable war fighting capabilities, it is important to maintain a good ammunition support system. In this paper, we evaluate the performance of Ammunition companies using Imprecise Data Envelopment Analysis (IDEA)-BCC and IDEA-Additive model, which can deal with imprecise data in DEA. In order to select a list of input and output variables, we used a multiple regression analysis. We could choose input variables that have significant effects on the output performance with stepwise regression model. From the regression analysis, the number of soldiers, officers, and ammunition warehouses were selected as the input variables. Seven out of sixteen Ammunition companies were found to be inefficient by the IDEA-BCC model. And using IDEA-Additive model, we could identify the input excess and the output shortfall in reaching at a point on the efficiency frontier.

  • In order to enhance sustainable war fighting capabilities, it is important to maintain a good ammunition support system. In this paper, we evaluate the performance of ammunition companies using Imprecise Data Envelopment Analysis (IDEA)-BCC and IDEA-Additive model, which can deal with imprecise data in DEA. The input variables of IDEA models were selected by stepwise multiple regression analysis. With the regression model, we could choose the number of soldiers, officers, and ammunition warehouses as input variables that have significant effects on the output performance. Then, we applied the IDEA-BCC model with the concept of potential efficiency. The results of the model indicate that 8 out of 16 ammunition companies are efficient, 7 are inefficient, and 1 is potentially efficient. We could also identify the possible input excesses and output shortfalls to reach the efficient frontier using the IDEA-Additive model.

  • This study was performed to determine the effect of patients with colon polypectomy on health behavior practices. Data were surveyed using interview and questionnaires by 112 patients with colon polypectomy in a general hospital who were located in Seoul from December 6, 2010 to January 31, 2011. Data were evaluated with t-test, ANOVA, Pearson correlation coefficient, and Stepwise multiple regression. The results were as follows: First, the higher control of life habit was, the more positive attitude(r=.350, p<.01) and the less inconvenience was significant correlation(r=-.263, p<.05). Secondly, in the stepwise multiple regression analysis, the most important factors influencing health behavior practices were control of life habit(${\beta}$=.392, p=.000), and then inconvenience of life(${\beta}$=-.265, p=.007), weight gain(${\beta}$=-.248, p=.024). In conclusion, positive attitude and control of life habit are necessary to improve the health behavior of patient with colon polypectomy.

  • The purpose of this study was to examine the relationships between anger expression, social supports, and adjustment to college life among nursing students. A convenience sample of 266 students in two colleges participated in the study. Data were analyzed using t-tests, ANOVA, Pearson correlation coefficients, and multiple stepwise regression. The mean score for adjustment to college life was above average. The mean score for adjustment to college life differed significantly according to students' reasons for applying to college and perceived health status. Adjustment to college life significantly correlated with anger expression and social supports. Multiple stepwise regression analysis showed that anger expression (Anger-Out, Anger-In, and Anger-Control), social supports, and perceived health status explained 27.1% of the variance in adjustment to college life. The study findings suggest that interventions intended to promote nursing students' adjustment to college life should focus on improving anger management, social supports, and perceived health status.
