This study is a descriptive study comparing the nursing work environment, job stress and turnover intention of pediatric ward nurses and general ward nurses. The subjects of this study were 174 nurses with more than one year of experience working in small hospitals, general hospitals and university hospitals with more than 200 beds in G-city. Data collection was conducted from August 2016 using structured questionnaires to measure nursing work environment, job stress and turnover intentions. Results: There were no significant differences in nursing work environment between pediatric ward nurses and general ward nurses, and there were significant differences in job stress. Especially, the more nursing work environment of pediatric ward nurses was, the higher the job stress, the higher the turnover intention. In other words, pediatric ward nurses are more likely to have higher job stress than regular ward nurses because they are stressed not only from the health problems of the child but also from the family members. Therefore, communication and self-achievement that can reduce the job stress of the pediatric ward nurse and a variety of measures are needed.

Purpose: This study is a structural model study to grasp the moderating effect of online and offline social support in interpersonal and depressive relationships of nursing students. Methods: This study surveyed 264 nursing students. The collected data is analyzed using Exploratory Factor Analysis, Confirmatory Factor Analysis, and PLS-SEM(Partial Least Square Structural Equation Model) using SPSS 25.0 and Smart PLS 3.0. Results: Interpersonal relationship problems and online social support had a significant effect on increasing depression, and offline social support had a significant effect on reducing depression. In addition, in the relationship between interpersonal problems and depression, only offline social support was found to be significant in the moderating effect. Conclusion: To reduce depression due to interpersonal problems of nursing college students, offline social support should be actively provided, and to investigate the moderating effect of online social support, a repetitive study is proposed that includes relevant variables such as social relationship types through SNS.

The purpose of this study is to characterize students' conceptions on causes of the phases of the moon. For this purpose, students were given a worksheet for argumentative writing activity where in they need to choose the right answer between five statements and provide reasonable evidences about causes of the phases of the moon. Written arguments collected were used as analysis data and TAP(Toulmin's argument pattern) including conceptual analysis of TAP elements were utilized to figure out logical structures and subordinate conceptions. The result showed that students had various alternative concepts about causes of the phases of the moon and associated with celestial. Also 70.5% of subjects had incomplete argument structures, and error types of concepts had difference according to types of alternative concepts as well as TAP. These results mean that importance of checking students' preconceptions, need of scientific argumentation, and appropriate instructional strategies considering alternative conception types and fallacy types that students had.

The purpose of this study was to examine the pre-service elementary teachers' views on the necessity of science learning. The eighty five student teachers in their second year of studies were participated in this study. The participants freely wrote their thoughts on a question'Why should students learn science?' The results of the study are as follows: (1) The participants' responses were very diverse, so their responses contained almost all kind of values or arguments about the science learning suggested by researchers, and there was no difference in their response ratio between views of focusing on intrinsic values and views of focusing on extrinsic values; (2) About 30% of the participants had the biased conceptions on the necessity of science learning and they would be likely to explain their biased conceptions to their future students. The educational implications and the suggestions for further studies are also presented in this paper.

Electric motor efficient improvement from home appliance field is important to the effect reducing the energy consumption. But the electric motor design/analysis technology is still insufficient. Specially the electric motor design/analysis technology of satisfying characteristic of both the induction motor and the synchronous motor such as Line start permanent motor. Therefore the electric motor design/analysis technology is urgently demanded reliability. This paper proposes the sing1e-phase line-start permanent magnet motor to develop the motor it with be able to alternate the sing-phase induction motor it is a refrigerator compressor motor. The sing-phase induction motor is analyzed in the steady state. And we have a certification test to compare our single-phase line-start permanent magnet motor with the sing-phase induction motor. In order to improve the performance, the stator of the single-phase line-start permanent magnet motor is same as the stator of the sing-phase induction motor and changes the rotor form and has the permanent magnet. It used the Finite Element Method(FEM) which is widely used with electronic-magnetic field numerical analysis method.

Film is a visual art. A process of film totally depends on our sense of sight. It indicates that a way of delivering narrative in the film is "showing", not "telling". There has already been established theories about "who sees" and "who tells" in narratology. It explains who the narrator is and how the narrator delivers in literary works which is represented in terms of "Point-of View". Therefore the study contents construct internal formal elements of the narrator and point of view into 2 individual researches, and the result can be summed up as below. From a narratological perspective, the narrator has roles and deeds as a narrative mediator who mediates the story and leads the story as presenting the origin with images and voices in the text extra and intra world through the process of producing the narrative inferred. To eliminate ambiguousness the term 'point-of view', this article applies 'focalization' theory to analyze narrative structure of film. The result of analysis shows that there are three focalizers in film; director, protagonist-character and camera. And aspects of film can be varied by distance of each focalizer. These distances between focalizers limit amount of visual information.
