The purpose of this study was to investigate workplace bullying, job stress, organizational commitment, and turnover intention as well as determine influencing factors on the turnover intention of small and medium-sized hospital nurses. Participants included 140 nurses from six small and medium-sized hospitals with less than 300 beds in G-city and J-province. Data were analyzed using descriptive statistics, independent t-test, one-way analysis of variance, Pearson's correlation coefficient, and stepwise multiple regression, using the SPSS Win 21.0 program. The regression model was statistically significant (F=37.11, p<.001), and the explanatory power for turnover intention was 34.2%. The significant factors influencing turnover intention were organizational commitment (β=-.41, p<.001 and job stress (β=.25, p=.005). Human resources management is crucial for providing high quality healthcare service. The results of this study indicated that it is important to lower job stress and increase organizational commitment in order to reduce turnover intention among nurses of small and medium-sized hospitals. Based on these findings, customized programs for nurses in small and medium-sized hospitals need to be developed and implemented so as to lower their turnover intention and promote efficient management of healthcare human resources.

The purpose of this study is to investigate how interactions and affective factors are influencing on-line English Grammar courses of higher education. This study addressed the following questions: (1) How are the interactions going in on-line English Grammar courses? (2) Are affective factors influencing effective learning in on-line English Grammar courses? The questionnaire was conducted on 170 college students who have taken on-line English course of K University. The data analysis of 300 college students' responses on their courses showed that e-learning has both positive and negative effects compared to face to face classroom instructions. Analysis showed that the percentage of students who have got negative opinions on e-learning was 17%, while that of students who have got positive opinions was 49.3%. The percentage of those in the middle was 33.3%. However, results demonstrated that immediate feedback and affective factors could be facilitated through Q&A bulletin and feedback program for completing on-line learning. Negative effects of on-line learning can be solved by a planned and well-supported on-line approach that includes a theory-based instructional model rather than the new method replaced by 'blended learning' that combines face-to-face classroom instruction with on-line learning.

We estimated the global inflow and stock of plastic marine debris. In South Korea, we estimated that the annual inflow of plastic marine debris (72,956 tons) was about 1.4% of annual plastics consumption (5.2 million tons) in 2012. By applying this 1.4% ratio to global plastics production from 1950 to 2013, we estimated that 4.2 million tons of plastic debris entered the ocean in 2013 and that there is a stock of 86 million tons of plastic marine debris as of the end of 2013, assuming zero outflow. In addition, with a logistic model, if 4% of petroleum is turned into plastics, the final stock of plastic marine debris shall be 199 million tons at the end. As the inflow and the stock are different units of measurement, better indicators to assess the effectiveness of inflow-reducing policies are needed. And, as the pollution from plastic marine debris is almost irreversible, countermeasures to prevent it should be valued more, and stronger preventive measures should be taken under the precautionary principle. As this is a preliminary study based on limited information, further research is needed to clarify the tendency of inflow and stock of plastic marine debris.

Wireless Mesh Networks (WMNs) have gained a lot of attention recently. Based on the characteristic of WMNs as a highly connected wireless infrastructure, many efforts from research organizations are made in order to improve the performance of the flow throughput in WMNs. Therefore, it is very critical issue to establish efficient routing paths for multiple concurrent ongoing flows. In this paper, we propose a general modeling methodology to analyze the end-to-end throughput of multiple concurrent flows by analytical calculation taking into account the carrier sensing behaviors, interference and the IEEE 802.11 Distributed Coordination Function mechanism. After the comparison of the average service time for each successful transmission at each node, we analyze the bottlenecks of flows, and hence obtain the maximum end-to-end throughput of them. By using our proposed model, it is possible to predicate the throughput of several candidate routing paths for multiple concurrent ongoing data flows, so we can select the most efficient route that can achieve the highest throughput. We carry out simulations with various traffic patterns of multiple flows in WMNs to validate our modeling and our efficient route selection mechanism.

While depressives tend to be preoccupied with their own grief and the negative aspects, they might lack the capacity to interact with outside world. With the intention to determine whether depressives might have certain characteristics regarding empathic behavior, as behavior is highly based on responsiveness to others, we examined the relationship between emotional empathy and depression. In addition, we examined the mediating effect of self-criticism on the relationship between emotional empathy and depression. Data was collected from 146 online university students and analyzed using the correlation and multiple regression model. Results showed that perspective taking, which is the cognitive aspect of empathy, was negatively correlated with depression. Concerning the emotional aspects of empathy, both empathic responding and empathic concern were negatively correlated with depression, while personal distress was positively correlated with depression. Regression results, which set the empathy related variables as predicting variables, found perspective taking decreased depression, and personal distress enhanced depression. In addition, personal distress showed significant enhancing effect on depression and was completely mediated by self-criticism. With the result, implications and limitations of this study were discussed.

This study was conducted to investigate factors influencing career maturity in nursing students. A convenience sample of 230 nursing student was selected from S city, between 20 October and 10 November 2017. Data were collected using a structured questionnaire and analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation, and multiple regression analysis with the SPSS/WIN 21.0 program. Factors that influenced career maturity included gender(t=2.117, p=.035), age(t=-2.572, p=.011), grade(F=4.716, p=.010), education at the time of admission(t=-2.695, p=.008) and perceived academic achievement(F=11.127, p<.001). Career maturity showed a positive correlation with career decision-making self-efficacy(r=.585, p<.001) and problem solving ability(r=.407, p <.001), but a negative correlation with job-seeking stress(r=-.424, p<.001). Regression analysis revealed that significant factors influencing career maturity were career decision-making self-efficacy, problem solving ability and job-seeking stress. This regression model explained 42.8% of the variance in the career maturity. Based on these findings, it is necessary to develop and test programs to ensure an improvement in career decision-making self-efficacy, problem solving ability and job-seeking stress among nursing students to increase their career maturity.
