  • Objective : This study aims to identify personality characteristics in female homicide offenders by using the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) test. Methods : This study retrospectively analyzed the mental appraisals and MMPI-2 scores of 54 women charged with homicide and 67 women charged with non-violent crimes, who were referred to National Forensic Hospital in Gongju city for psychiatric evaluation between January 2012 and March 2016. Results : Women charged with homicide scored significantly higher on Hs (p=0.018), D (p<0.001), Hy (p=0.002) and Pt (p=0.004) than the women charged with non-violent crimes. The women charged with homicide may have developed the following characteristics: hypochondriasis, depression, hysteria and psychasthenia. In multiple regression analyses, a final regression model including age of crime onset and depression was significant, explaining 16.5% of the variance in homicides committed by females. Conclusion : These findings suggest that personality characteristics in the female homicide offenders might be different compared to the non-violent crime offenders.

  • Purpose: Purpose of this study was to investigate relationships and influence of peripheral neuropathy, sleep, and quality of life in patients with gastric cancer who are receiving chemotherapy. Methods: Participants were 131 patients with gastric cancer being treated at a chemotherapy outpatient clinic and receiving chemotherapy. Data were analyzed using descriptive statistics, t-test, ANOVA, and multiple regression analysis with the SPSS program. Results: Mean score for peripheral neuropathy was 24.66, for sleep, 6.71 and for quality of life, 67.69. Peripheral neuropathy had a significant positive correlation with sleep (r=.26, p=.003) and sleep had a significant negative correlation with quality of life (r=-.50, p<.001). The regression model explaining quality of patients'lives was significant (F=11.91, p<.001), peripheral neuropathy, sleep, and pain due to anticancer drugs and number ofneurotoxic anticancer drugs explained 25.1% of the variance in quality of life and sleep was the most important factor. Conclusion: To improve the quality of life for these patients, individualized nursing interventions for pain should be provided according to number of anticancer drugs in the chemotherapy. Also there is a need to identify ways to assess peripheral neuropathy and sleep disorders that are appropriate in the treatment and reduce side effects during treatment.

  • Purpose: The purpose of this study was to identify the related factors of change affecting the stages of change for exercise, on the assumption that there are various stages of change in the exercise behavior of women in nursing college. Methods: The subjects were 496 female college students in D city. The research instruments were stages of change for exercise behavior, the process of change, decisional balance, and self-efficacy. The dates were analyzed by descriptive statistics, ANOVA, and stepwise multiple regression using the SPSS 18.0 program. Results: The distribution of the subjects across the stages was: pre-contemplation, 17.7%; contemplation, 58.7%; preparation, 19.0%; action, 2.8%; maintenance, 1.8%. Analysis of variance showed that cognitive process (F=17.26, p<0.01), behavioral process (F=27.05, p<0.01), the pros of decisional-balance (F=7.07, p<0.01), the cons of decision-balance (F=5.82, p<0.01), and self efficacy (F=17.79, p<0.01) were significantly associated with the change of exercise behavior stages. The related factors of change affecting the change of exercise behavior stage were the cons of decision-making, counter conditioning, self re-evaluation, and body mass index, including 28.4% R-square. Conclusion: The transtheoretical model would be applicable to explain the exercise behavior of some women in nursing college. So, this study will be useful information for developing effective exercise behavior programs considering female students' stages of change.

  • The leaching of Cu from waste PCBs was investigated with electro-generated chlorine as an oxidant. The leaching experiments were carried out according to the design of experiments to analyze quantitatively the effect of parameters on copper leaching. From the analysis of variance (ANOVA) it was suggested that the effective parameters were current density, temperature, concentration of HCl, and the interaction between the concentration of HCl and temperature. Especially, the effect of current density was analyzed to contribute to the interpretation of result for copper leaching up to 95.7%. A multiple regression model obtained from the analysis of effective parameters explained 99% of leaching results. From the model equation, it was found that the effect of HCl concentration on copper leaching increased with temperature.

  • Purpose: As Korea has been rapidly transformed to be a multicultural society, it becomes essential for nurses to develop cultural competency. The purpose of this descriptive study was to assess the cultural competency level of general hospital nurses and to examine its contributing factors adopting ecological model. Method: A convenience sample of 327 nurses from six general hospitals in Seoul metropolitan area was recruited between November 14 to 28, 2011. Cultural competency was measured using the Korean version of the Caffrey Cultural Competence in Healthcare Scale (CCCHS) and Cultural Competence Assessment(CCA). Hierarchical multiple regression analysis was performed to assess the influence of intrapersonal, cultural-experience, and organizational factors on cultural competency. Results: Mean cultural competency in this study was 2.57(${\pm}0.43$). Cultural competency was associated with job position (p=.044) at the intrapersonal level. At the cultural experience level, foreign language classes experience (p=.005), fluency in a foreign language (p=.000), experience of working with foreign health care professionals (p=.000) were associated cultural competency. At the organizational level, training program (p=.000), job description (p=.002), health education materials (p=.016), insufficient job control (p=.000), and interpersonal conflicts (p=.011) showed significant difference. Foreign language class experience, foreign language fluency, experience of working with foreign health care professionals, and job control were the most consistent predictors of cultural competence and explained 20.4% of the total variance in the proposed ecological model. Conclusions: The findings suggest that to enhance cultural competency in general hospital nurses, cultural experience and organizational factors need to be more fully considered than intrapersonal factors.

  • This study investigated the impact of solution-focused thinking on marital satisfaction via mediating roles of father involvement in childcare and marital conflict. A questionnaire survey was conducted among mothers with infants, living in Busan, Daegu and Yangsan, South Korea. Data from 264 mothers were analyzed using several multiple regression analyses and bootstrapping method with SPSS 25.0 and PROCESS macro (model 6) to test the serial double mediation model. The results of this study are as follows. First, mothers' solution-focused thinking had a significant direct and indirect positive influence on marital satisfaction through both father involvement in childcare and marital conflict. Second, the sequential mediating effects of father involvement in childcare and marital conflict were statistically significant in the relationship between solution-focused thinking and marital satisfaction. The model accounted for 60% of the variance in mothers' marital satisfaction. The results highlight the importance of solution-focused thinking that can enhance the marital satisfaction of mothers with infants and act as a resource for increasing father involvement in childcare and decreasing marital conflict. Based on the results, it is necessary to include solution-focused thinking, father involvement in childcare, and marital conflict as key elements in the intervention to improve marital satisfaction of mothers with infants.

  • From the traffic analyses, and model constructions and verifications for speed prediction on the freeway ramp junctions with 70mph speed limit, the following results obtained: ⅰ) The traffic flow distribution showed a big difference depending on the time periods. Especially, more traffic flows were concentrated on the freeway junctions in the morning peak period when compared with the afternoon peak period. ⅱ) The occupancy distribution was also shown to be varied by a big difference depending on the time periods. Especially, the occupancy in the morning peak period showed over 100% increase when compared with the 24hours average occupancy, and the occupancy in the afternoon peak period over 25% increase when compared with the same occupancy.ⅲ) The speed distribution was not shown to have a big difference depending on the time periods. Especially, the speed in the morning peak period shown 10mph decrease when compared with the 24hours' average speed, but the speed did not show a big difference in the afternoon peak period.ⅳ) The analyses of variance showed a high explanatory power between the speed predictive models(SPM) constructed and the variables used, especially the upstream speed. ⅴ) The analysis of correlation for verifying the speed predictive models(SPM) constructed on the ramp junctions were shown to have a high correlation between observed data and predicted data. Especially, the correlation coefficients showed over 0.95 excluding the unstable condition on the diverge sectionⅵ) Speed predictive models constructed were shown to have the better results than the HCM models, even if the speed limits on the freeway were different between the HCM models and speed predictive models constructed.

  • The low birth rate in South Korea is a very serious problem. Recently, as personal happiness has emerged as an important life value of life, unmarried people have developed a negative tendency toward marriage. This study was conducted to investigate the attitude toward marriage, gender role and having children among college students, and to identify the factors affecting marriage. The participants were 383 unmarried nursing college students who live in D city. Data were collected from self-report questionnaires and analyzed using the t-test, one-way ANOVA, Pearson's correlation coefficients, and stepwise multiple regression using the SPSS 22.0 program. Gender was a significant variable influencing attitude toward marriage. Moreover, the attitude toward marriage was negatively correlated with gender role, and positively correlated with having children. Attitude toward gender role was negatively correlated with having children. Regression analysis of the factors affecting attitude toward marriage showed that gender (male), attitude toward gender role, and attitude toward having children were significant influencing factors. Moreover, this model explained 51.9% of variance in attitude toward marriage. Overall, it is necessary to change individual values to solve the problem of low birthrate.
