Purpose: This study aimed to develop a smartphone overdependence prevention program for college students based on the self-determination theory (SDT) and evaluate its effectiveness. Methods: A non-equivalent control group repeated measures design was used for the study. Participants were 64 university freshmen (experimental group: 29, control group: 35). The developed program consists of eight sessions conducted twice a week. The program was designed to promote autonomy, competence, and relatedness the three elements of the basic psychological needs of self-determination theory. The participants were assessed before the program, immediately after, and 1 and 3 months after the program. Data were collected from April 23 to September 14, 2018 and analyzed by performing a Chi-square test, Fisher's exact test, independent t-test, and repeated measures ANOVA using SPSS/WIN 23.0. Results: This study showed improvement in the basic psychological needs (F=3.90, p=.010) in the experimental group compared to the control group. Specifically, competence (F=2.93, p=.035), relatedness (F=2.89, p=.045), and self-regulatory ability (F=3.11, p=.028) improved significantly. Conclusion: Study findings indicate that the smartphone overdependence prevention program based on the Self-determination theory could be an effective intervention for improving basic psychological needs and self-regulation ability. Therefore, this program could be an efficient strategy for smartphone overdependence prevention in university students.

This study investigated whether adolescents' perception s of coaching behavior and social behaviors differ by gender and sport career, and examined the relationships among these variables. Subjects were 740 high school athletes (516 males, 224 females). Data were analyzed using descriptive statistics, correlation, and 2(gender)${\times}3$(sport career) MANOVA. Results of MANOVA indicated that the interaction between gender and sport career significantly influenced to the level of prosocial behaviors on opponents. Male athletes perceived their coaches' behaviors more controlled and showed higher antisocial behaviors to opponents than female athletes. Athletes with low sport career reported higher antisocial behaviors on opponents than those with high careers. Autonomy-supportive coaching behaviors were positively associated with prosocial behaviors, but negatively related with antisocial behaviors. Controlled coaching behaviors were positively associated with antisocial behaviors.

Unlike in the past, successful global companies are striving to create a horizontal organizational structure and autonomous corporate culture by empowering their members with autonomy and responsibility. The purpose of this study is to conduct an empirical analysis on the effect of job stress and managerial coaching behavior on the effect of psychological empowerment on organizational commitment and turnover intention. Negative situational factors (job stress) and positive situational factors (managerial coaching behavior) were considered and presented at the same time, and their effectiveness was verified. As a result of the analysis, it was found that psychological empowerment had a positive effect on organizational commitment, but did not to affect turnover intention. Also, it was found that job stress and managerial coaching behavior had a mediating effect. The results of this study can be used as a effective guideline on creating an autonomous organizational climate and creating a successful corporate culture through this.

Currently, the Republic of Korea is facing the problem of a decrease in military service resources due to the demographic cliff, and is pursuing military restructuring and changes in the military force structure in order to respond to this. In this situation, the Army is pushing forward the deployment of a drone-bot combat system that will lead the future battlefield. The battlefield of the future will be changed into an integrated battlefield concept that combines command and control, surveillance and reconnaissance, and precision strike. According to these changes, unmanned combat system, including dronebots, will be widely applied to combat situations that are high risk and difficult for humans to perform in actual combat. In this paper, as one of the countermeasures to these changes, autonomous behavior software with a BDI architecture-based decision-making system was developed. The autonomous behavior software applied a framework structure to improve applicability to multiple models. Its function was verified in a PC-based environment by assuming that the target UAV is a battalion-level surveillance and reconnaissance UAV.

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.

The intensive care unit (ICU) is the most common place to die. Also, ethical conflicts among stakeholders occur frequently in the ICU. Thus, ICU clinicians should be competent in all aspects for ethical decision-making. Major sources of conflicts are behavioral issues, such as verbal abuse or poor communication between physicians and nurses, and end-of-life care issues including a lack of respect for the patient's autonomy. The ethical conflicts are significantly associated with the job strain and burn-out syndrome of healthcare workers, and consequently, may threaten the quality of care. To improve the quality of care, handling ethical conflicts properly is emerging as a vital and more comprehensive area. The ICU physicians themselves need to be more sensitive to behavioral conflicts and enable shared decision making in end-of-life care. At the same time, the institutions and administrators should develop their processes to find and resolve common ethical problems in their ICUs.

Maintaining agility and responsiveness m designing and manufacturing activities are the key issues for manufacturing companies to cope with global competition. Distributed design and control systems are regarded as an efficient solution for agility and responsiveness. However, distributed nature of a manufacturing system complicates production activities such as design, simulation, scheduling, and execution control. Especially, existing simulation systems have limited external integration capabilities, which make it difficult to implement complex control mechanisms for the distributed manufacturing systems. Moreover, integration and coupling of heterogeneous components and models are commonly required for the simulation of complex distributed systems. In this paper, a collaborative and adaptive simulation architecture is proposed as an open framework for simulation and analysis of the distributed manufacturing enterprises. By incorporating agents with their distributed characteristics of autonomy, intelligence, and goal-driven behavior, the proposed agent-based simulation architecture can be easily adapted to support the agile and distributed manufacturing systems. The architecture supports the coordination and cooperation relations, and provides a communication middleware among the participants in simulation.

Multi-agent technology is being regarded as one of the promising technologies for today's supply chain management because of its desirable features such as autonomy, intelligence, and collaboration. This paper suggests a multi-agent system architecture with which companies can improve the efficiency of their supply chains by collaborative operation. Reflecting the practical difficulties of collaboration in complex supply chains, the architecture allows agent systems to share information with only neighboring companies for the coordinated operation. The suggested architecture is elaborated with a collaboration model based on Petri-net, conversation models for communication, and internal behavior models of each agent. A simulation experiment was performed for the evaluation of the suggested architecture. The result implies that when the estimation of market demand is higher than a certain level, the suggested architecture can be beneficial.

The purpose of the present study was to examine how dimensions of socialization practice and relationship quality may function to manage or increase parent-adolescent conflict. Of particular concern was to examine the comparative efficacy of potential predictors of parent-adolescent conflict across three cultural groups consisting of samples from Mainland China, Russia, and the U.S. as well as across gender-of-parent/gender-of-adolescent dyads from each culture. Findings from a sample of 1,365 adolescents indicated that adolescents' perceptions of parental influences on parent-adolescent conflict differ across cultural groups and gender-of-adolescent. The use of punitive behavior by parents was the strongest and most consistent predictor of parent-adolescent conflict across all cultural groups and gender dyads, suggesting that a general pattern exists for punitiveness to increase parent-adolescent conflict cross-culturally. Perceptions of support, monitoring, conformity to parents, and autonomy from parents influenced parent-adolescent conflict within some of the cultures and selectively for adolescent boys and girls.

Under feudalism, besides imploring investiture, tribute is said to be one of the two most typical activities at the core of diplomatic relations between China and the region, in particular, Vietnam and Japan. By using the comparative method and interdisciplinary approach, the author shows that there are many differences between Vietnam and Japan with regards to tribute activity with China during the feudal period. For example, the start and end of China's tributary activities with Vietnam and Japan are not the same. The period of Japanese tributary activity was much more loosened than Vietnam. Vietnamese tributary relation was political, while Japan placed economic benefits as the main priority. In particular, the author also proved that although Japan and China had differences in behavior and level of dependence on the tributary activity of Vietnam, both Vietnam and Japan maintained independence and autonomy. Based on the historical, cultural, and geographical characteristics, as well as the position and force correlation of each country in relation to China, this article also explains the causes of these similarities and differences.
