  • Purpose : The purpose of this study is to investigate nursing students' levels of and relationships between college-related stress, self-efficacy, social support, and interpersonal skills. Methods : This study involved 352 nursing students at K University in B City, each who understood the study's purpose and agreed to participate in the study. The study's data were collected between April 8 and 19, 2019 and were analyzed using the SPSS for Windows 22.0 program based on frequencies, percentages, means, and standard deviations as well as a t-test, analysis of variance, post-hoc test, and correlation analysis results. The Scheffe test was performed for the post-hoc test, and the Pearson correlation coefficient was employed for the correlation analysis. Results : College-related stress showed statistically significant negative correlations with self-efficacy (r=-.310, p<.001), social support (r=-.312, p<.001), and interpersonal skills (r=-.226, p<.001). However, self-efficacy exhibited statistically significant positive correlations with social support (r=.548, p<.001) and interpersonal skills (r=.524, p<.001), and social support showed a statistically significant positive correlation with interpersonal skills (r=.644, p<.001). Therefore, higher levels of self-efficacy and social support and a lower level of college-related stress result in corresponding higher levels of interpersonal skills. Conclusion : Based on the results of this study, it is necessary to find measures to lower nursing students' college-related stress and increase their self-efficacy and social support, as well as to develop and operate specific intervention programs that can help enhance their interpersonal skills.

  • In this study, "housewives" are defined as married women who take care of housework mostly and do not work outside of home. Changing family types and higher education level of housewives enable them to be more interested in heath, beauty, and appearance. Increased interest and more frequent visits to hair salons cause scalp damage as well as hair damage, which results in hair loss. Moreover, some women suffers from scalp and hair damage due to childbirth, but many of them are not aware of it. Therefore, this study tries to find out the following; housewives' perceptions on hair and scalp management, and how such perceptions are formed. In addition, this study will present the direction for beauty marketing taking into account the characteristics of housewives and provide data necessary for them to keep their hair and scalp healthy. For these purposes, a survey was carried out after modifying the questionnaire through a presurvey. The survey tried to find 1) perceptions on hair and scalp management according to demographic characteristics, and attitude toward hair and scalp management according to demographic characteristics. Data were analyzed using frequency analysis, cross tabulation, t-test, factor analysis, and Analysis of Variance. The results were as follows, most recognize the importance of hair and scalp management but do not receive management because of the high cost, most of them receive information about hair and scalp management from people around them, and the higher the education level and health status, the more active the attitude toward hair and scalp management. These differences were all statistically significant.

  • Purpose: The purpose of this study was to develop a maternal nursing competency reinforcement program for nursing students and assess the program's effectiveness in Korea. Methods: The maternal nursing competency reinforcement program was developed following the ADDIE model. This study employed an explanatory sequential mixed methods design that applied a non-blinded, randomized controlled trial with nursing students (28 experimental, 33 control) followed by open-ended interviews with a subset (n=7). Data were analyzed by both qualitative and quantitative analysis methods. Results: Repeated measures analysis of variance showed that significant differences according to group and time in maternal nursing performance; assessment of and intervention in postpartum uterine involution and vaginal discharge (F=24.04, p<.001), assessment of and intervention in amniotic membrane rupture (F=36.39, p<.001), assessment of and intervention in delivery process through vaginal examination (F=32.42, p<.001), and nursing care of patients undergoing induced labor (F=48.03, p<.001). Group and time improvements were also noted for problem-solving ability (F=9.73, p<.001) and emotional intelligence (F=4.32, p=.016). There were significant differences between groups in self-directed learning ability (F=13.09, p=.001), but not over time. The three main categories derived from content analysis include "learning with a colleague by simulation promotes self-reflection and learning," "improvement in maternal nursing knowledge and performance by learning various countermeasures," and "learning of emotionally supportive care, but being insufficient." Conclusion: The maternal nursing competency reinforcement program can be effectively utilized to improve maternal nursing performance, problem-solving ability, and emotional intelligence for nursing students.

  • Purpose: The purpose of this study was to examine the correlations among emotional perception clarity, emotion regulation, family relationship, non-suicidal self-injury, and depression, and to determine associated factors of non-suicidal self-injury and depression for senior elementary school students. Methods: Data were collected from 150 early adolescences in K region, Korea. A self-report questionnaire consisted of Trait Meta-Mood Scale, Cognitive Emotion Regulation Questionnaire, Family Relationship Assessment Scale, Functional Assessment of Self-Mutilation, and Children's Depression Inventory. The data were analyzed using t-test, Pearson's correlation coefficient, logistic regression, and multiple regression analysis. Results: Non-suicidal self-injury and depression were positively associated with maladaptive emotion regulation strategy and family conflict, but negatively related to emotional perception clarity and family support. Adaptive emotion regulation strategy and family togetherness were only significantly correlated with depression. In logistic regression analysis, significant predictors of non-suicidal self-injury were emotional perception clarity, maladaptive emotion regulation strategy, and family support. Multiple regression analysis found that significant factors of depression were adaptive and maladaptive emotion regulation strategies, which explained 38.0% of the variance. Conclusion: Our study findings suggest that targeted intervention to reinforce the adaptive emotion regulation strategy and family relationship may prevent non-suicidal self-injury, and depression for senior elementary school students.

  • Recently, studies on the integrity of rotating machines, such as gantry cranes, which are used in the shipbuilding industry, have been actively conducted. Gantry cranes are driven at relatively low revolutions per minute (RPM), are frequently operated and stopped, and are impacted by external environmental factors, such as shock and noise in the measurement data. The purpose of this study was to construct a replica of a gantry crane hoist used in indoor shipbuilding and analyze the acquired data for errors caused by the shift in operating conditions (RPM) and the change in the position of the data acquisition sensor. Consequently, we observed that the error caused by differences in sensor positions did not occur significantly under low operating conditions but occurred significantly under relatively high operating conditions. Thus, we determined that both the operating condition and position of the acquisition sensor affected the data acquired by the rotary machine.

  • In this paper, in order to study the relationship between the safety culture of highway management agencies and disaster reduction activities (BCMS), a measurement tool was identified through previous research on safety culture, and the validity of the measurement tool was confirmed through exploratory factor analysis. I want to check. The subjects of the study were workers belonging to disaster reduction activity management system certification organizations among highway management organizations. The highway management agencies are the Korea Expressway Corporation, which manages the functional continuity of national highways nationwide, and 8 of the 21 private road agencies that manage the functional continuity of the highways. The safety culture measurement tool is an indicator that measures safety culture factors, and is reorganized by the researcher based on survey items from previous studies, with management/manager safety values and attitudes, safety communication, safety education and training, and safety regulations/management system as subfactors. A total of 24 questions were comprised of the survey tool. As a result of the study, the result of exploratory factor analysis was that the safety culture scale was extracted into four factors based on theoretical grounds, and the total cumulative variance was 80.360%. When checking the questions for each factor, it was found that all the questions loaded on the factor that was originally intended to be measured. Factor 1 is management, factor 2 is safety, and factor 3 is communication., Factor 4 was named education. Number of questions: 4 management questions, 3 safety questions, communication It consisted of 4 questions and 2 education questions.

  • Purpose: This study was to test the reliability and validity of a Drinking Refusal Self-Efficacy Questionnaire-Revised (DRSEQ-R) in Korean college students, Methods: The DRSEQ-R was designed to assess an individual's belief in their ability to refuse drinking alcohol by Oei et al. (2005) and consisted of three factors (social pressure, opportunity, and emotional relief). A methodological study design with an exploratory factor analysis for validity and correlation coefficients for reliability was used. DRSEQ-R was translated into Korean and a translation equivalency was obtained. DRSEQ-R was tested with a sample of 201 college students in Korea. The subjects consisted of 106 males and 95 females. Principal component factor analysis was used for construct validity and Cronbach's alpha was used to evaluate for internal consistency of the instrument. Results: The factor analysis showed three factors explaining 66.3% of total variance and the corresponding factors were emotional relief (48.01%), drinking contextual opportunity (11.18%), and social pressure (7.14%). The internal consistency was acceptable (Cronbach's alpha=.937). All three factors of DRSEQ-R negatively correlated with alcohol dependency and a heavy drinker showed a lower DRSEQ-R than a moderate drinker. Conclusion: Based on the findings, DRSEQ-R is a reliable and valid instrument to measure for drinking refusal self-efficacy in Korean college students.

  • Nowadays, most micro-patterns are manufactured during flow line production. However, a conventional rotary chemical mechanical polishing (CMP) system has a limited throughput for the fabrication of large and flexible electronics. To overcome this problem, we propose a novel linear roll-CMP system for the planarization of large-area electronics. In this paper, we present a statistical analysis on the linear roll-CMP process of copper-clad laminate (CCL) to determine the impacts of process parameters on the material removal rate (MRR) and its non-uniformity (NU). In the linear roll-CMP process, process parameters such as the slurry flow rate, roll speed, table feed rate, and down force affect the MRR and NU. To determine the polishing characteristics of roll-CMP, we use Taguchi's orthogonal array L16 (44) for the experimental design and F-values obtained by the analysis of variance (ANOVA). We investigate the signal-to-noise (S/N) ratio to identify the prominent control parameters. The "higher is better" for the MRR and "lower is better" for the NU were selected for obtaining optimum CMP performance characteristics. The experimental and statistical results indicate that the down force and roll speed mainly affect the MRR and the down force and table feed rate determine the NU in the linear roll-CMP process. However, over 186.3 N of down force deteriorates the NU because of the bending of substrate. Roll speed has little relationship to the NU and the table feed rate does not impact on the MRR. This study provides information on the design parameter of roll-CMP machine and process optimization.

  • The purpose of this study was to determine the attributes and factors of brand personality for contract foodservice management companies. Self-administered questionnaires were distributed to five students at universities operating under the top five companies in contract foodservice management. The following statistical analyses were conducted for the data assessment: descriptive analysis, t-test, ANOVA, reliability analysis, and factor analysis, using the SPSS Win(12.0) package program. From these analyses we divided a company's brand personality into the following five functional and emotional elements: sensibility, sincerity, confidence, competence, and excitement. Based on these five elements a total of 26 scales were developed to measure brand attributes of the companies. The variance was explained by 19.29% of sensibility, 17.65% of sincerity, 15.71% of confidence, 14.06% of competence, and 13.62% of excitement. The calculated Cronbach's alpha was more than .90 for all the scales measuring the five attributes, indicating good internal consistency. There were significant differences in sensibility(p<.01), sincerity(p<.001), creditability(p<.01), competence (p<.001), and excitement(p<.001) among the companies. In regards to overall brand personality, company a had a higher mean score for sincerity, while the other companies had higher mean scores for competence. Among the brand personalities, 'confidence' had the highest mean score with 3.36, followed by 'cooperation' (3.17), 'successful'(3.12), 'leadership'(3.11), and 'down-to-earth'(3.02).
