This study is tried to to identify factors affecting academic achievement depending on the quality of class, learning immersion, level of academic achievement, and class type according to video production classes and real-time video classes in the on-contact learning situation due to the COVID-19 epidemic. The subjects of the study were 122 students enrolled in the nursing department at two universities. As a result of the study, the quality of the class was high in real-time video classes (t=-2.69, P=0.02), learning immersion was high in video production classes (t=1.14, P=0.28), and academic achievement was high in video production classes (t=4.24, P=0.01). Depending on the type of class, the effect on academic achievement is learning immersion in production video classes (β=.37, p<.001) has the most influence, and in real-time video classes, class quality (β=.29, p<.001) had the most influence on academic achievement. Based on the results of this study, it is suggested that it is necessary to develop a strategy for instructional design suitable for class types to improve academic achievement in an on-contact environment.

This study was conducted to analyze the effects of peer tutoring programs and to introduce the peer tutoring program in medical College. Forty medical students participated in the study and data were collected through surveys and interviews. Through the interviews, we investigated the peer tutoring experiences of tutors and tutees, and what they perceived that they accomplished. Correlation analysis was conducted to investigate the tutoring process variables that affect the academic achievement of tutees. It was found that tutors and tutees reported achievements in the schoolwork, relationships, and emotional aspects.

Purpose: The purpose of this study was to explore the clear concept of organizational commitment for effective nursing personnel management. Method: This study was conducted using Walker & Avant's conceptual analysis framework(2005). Results: Organizational commitment was identified with six attributes: acknowledgment, acceptance, trust, sacrifice, attachment, regulation. Antecedents of organizational commitment were personal characteristics, perceived organizational support, empowerment, fair compensation, job satisfaction, job autonomy, organizational culture, and leadership. Consequences of organizational commitment were turnover intention, job performance and organizational citizenship behavior. Conclusion: Organization commitment is a core concept for understanding the management of nursing personnel. Appropriate instruments to operationalize the concept of organizational commitment including six attributes need to be developed.

Purpose: The study examined differences in stress between the parents of sick newborns. Methods: Participants were the mothers (n=57) and fathers (n=57) of newborns in NICU of six university hospitals. An established stress measurement tool (Miles and Carter, 1993) was used. Results: Fathers and mothers displayed the highest stress scores (4.44 and 4.67, respectively) when the baby looked in pain. Maternal overall stress scores were significantly higher than paternal scores. Conclusions: Mothers and fathers experience differing levels of stress concerning their newborn. Further studies are needed to develop customized stress management intervention programs for parents of newborns in the NICU.

Purpose: The purpose of this study was to investigate the level and factors influencing depression among nursing students. Methods: The data were collected from nursing students attending 3 universities who expressed a willingness to participate in the study through a questionnaire which surveyed them about depression, stress, social support, self-efficacy, self-esteem, and wellbeing in May, 2012. The collected data from 235 nursing students were analyzed using a SPSSWIN 19.0. Results: The mean score of depression (using MDI) among nursing students was 16.7, which denotes a minor depressive mood. 49.1% of variance with regard to depression among nursing students was explained by stress, self-esteem, wellbeing and self-efficacy. Conclusion: There is a need to develop a depression prevention program for nursing students and to reduce stress and increase self-esteem, wellbeing and self-efficacy in order to establish an effective program.

Purpose: The purpose of this study was to investigate the effects of positive thinking and self-esteem on school adaptation among freshmen in a nursing department. Methods: Data were collected by questionnaires from 172 nursing students in the month of December 2017. The collected data were analyzed using descriptive statistics, an independent t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression. Results: A positive correlation was found for school adaptation with positive thinking and self-esteem. Positive thinking, self-esteem, major satisfaction and interpersonal relationships were all significant predictors of school adaptation. The model explained 43.6% of the variables. Conclusion: The results of this study suggest that positive thinking should be considered when developing strategies to increase school adaptation among freshmen in nursing departments.

Purpose: To test whether a hope carries the influence of pain to health related quality of life in patients with cancer. Method: 114 cancer patients recruited with. Data were collected through the Visual analog Scale, the Herth Hope Index, and the SF-36 Standard Korean Version. Results: The results showed that the measurement variables (pain, hope and health-related quality of life) were all significantly interrelated. The results of MedGraph revealed that the full mediation effect of hope in the relation between pain and mental component summary of quality of life was significant. Conclusion: These results imply that hope need to be considered in planning intervention programs for the enhancement of quality of life in patients with cancer.

A Wireless Body Area Network (WBAN) allows the seamless integration of miniaturized sensor nodes in or around a human body, which may cause damage to the surrounding body issue due to high temperature. Although various temperature aware routing protocols have been proposed to prevent temperature rise of sensor nodes, most of them accommodate single traffic transmission with no mobility support. We propose a Forwarder based Temperature Aware Routing Protocol (FTAR) that supports multiple traffic transmission for normal and critical data. Normal data is forwarded directly to the sink through forwarding nodes which are selected among mobile nodes attached to the arms and legs, while critical data is forwarded to the sink through static nodes attached to fixed body parts with no mobility. We conduct extensive simulations of FTAR, and conclude that FTAR has good performance in terms of hot spot generation ratio, hot spot duration time, and packet delivery ratio.

In this paper, a novel technique that improves the performance of generalized mixture decomposition algorithm (GMDA) based on pre-training phase unwrapping. From the investigation of the GMDA scheme, it was discovered that the conventional GMDA technique cannot fully consider phase unwrapping, because the estimated inter-channel phase difference (IPD) slope is initialized randomly. To avoid this phenomenon, the proposed GMDA approach initialized the IPD slope from the data of low-frequency bins. Experimental results show that comparing to the conventional GMDA technique, the proposed GMDA technique based on pre-training phase unwrapping obtains a lower estimation error. When integrated into a source localization system, the result of source localization is improved.

Mobile sinks are being exploited for various purposes for solving the hotspot problem. Thus, the mobility support technique of mobile sinks is important, and it has been studied steadily. A survey was conducted of studies of mobile sinks in sensor networks having different movement patterns depending on the applications. The related techniques were divided into three main categories according to mobility pattern: predefined, random, and control. In addition, communications for mobile sinks are strongly affected by whether there is a single mobile sink or multiple ones. Based on this two-level categorization, an overview is presented of some state-of-the-art mobility support techniques researched during the past three years, and then the technique are analyzed according to various criteria. Finally, this survey concludes with a summary and a discussion of some future research challenges.
