This paper is meaningful in that it empirically studies the good job condition of which young people think and the impact of job search behavior on employment. In addition, employment status and additional job search performance were set as performance variables. The main research results of this study are as follows. First, as for the good job condition considered by young people, wages and salaries in terms of companies, job stability in terms of environment, and work-life balance in terms of individuals were found. Second, job search behavior was found to be a key variable influencing employment status and job search performance. Third, it was found that job-search stress injures employment. Finally, work experience promotes employment and job search performance. Therefore, to increase the employment success rate of young people, above all, various supports for increasing the frequency of young job seekers' active job search behavior are needed. To this end, it suggests that it is necessary to develop a customized youth policy service model and to provide systematic services to meet the needs of young people.

The purpose of this study is to investigate the level of verbal abuse experiences, emotional labor, and health-promoting behaviors of nurses in small and medium hospitals and to identify the relationship between them. Participants were 138 nurses from 2 small-medium sized hospitals. Collected data were analyzed using t-test, ANOVA, and Pearson's correlation coefficients with the SPSS 20.0 for Windows Program. As a result of the study, 82.7% of them experienced verbal abuse, and there were differences in the degree of health- promoting behavior according to gender (p=.032) and department (p=.009). Besides, it was found that emotional labor was related to health-promoting behavior (p=.039), and spiritual growth (p=<.01), and stress management (p=.028) as sub-factors. Accordingly, this study will be used as basic data for developing strategies and customized programs to reduce emotional labor, increase health-promoting activities, and contribute to the stable securing of nursing personnel.

By changing the bulky monolithic services architecture to a microservices-based architecture, industries are managing the rising complexity of Autonomous Vehicles. However, the underlying communication mechanisms for the utilization and distribution of these microservices are incapable of fulfilling the requirements of the futuristic AV, because of the stringent latency requirements along with intermittent and short-lived connectivity issues. This paper proposes to tackle these challenges by employing the revolutionary information-centric networking (ICN) paradigm as an underlying communication architecture. This paper argues that a microservice approach to building autonomous vehicle systems should utilize ICN to achieve effective service utilization, efficient distribution, and uniform service discovery. This research claims that the vision of an information-centric microservices will help to focus on research that can fill in current communication gaps preventing more effective, and lightweight autonomous vehicle services and communication protocols.

Since recently only an auto-correlated superposition coding (SC) scheme for non-orthogonal multiple access(NOMA) has been investigated, this paper proposes a cross-correlated SC scheme for NOMA. First, we derive the closed-form expression of the sum rate of the proposed cross-correlated SC scheme. Then, numerical analyses demonstrate that the sum rate of the proposed cross-correlated SC scheme is larger than that of the conventional auto-correlated SC scheme. We also show that for the stronger channel gain user, the signal-to-noise ratio (SNR) gain of the proposed cross-correlated SC scheme is about 15, compared with the conventional auto-correlated SC scheme. As a result, the proposed cross-correlated SC scheme could be a promising technology for 6G ultra-reliable low-latency communications (URLLC).

This study analyzes the differences in perception of cosmetic quality (safety, stability, functionality, usability) and satisfaction according to consumer characteristics, targeting 317 men and women from their 18 to 50s who use cosmetics in Seoul and Gyeonggi Province, and the differences in effect of cosmetic quality perception on satisfaction according to side effects experience was analyzed. Among the cosmetic quality factors, the usability was satisfied, but the perception of safety, stability, and functionality was low, so overall quality improvement was necessary. In particular, the quality perception and satisfaction by men and 40s was low, so a customized solution was needed for this. In the order of usability and functionality, to both those experiencing or not side effect, had a significant positive effect on the satisfaction level, and the improvement of usability and functional awareness was the main factor that increased satisfaction. Improving product quality and supplementing factors that positively influence consumer perception are thought to be of great help in improving quality perception and satisfaction.

In spite of various safety measures, coastal safety accidents continue to occur, so this study focused on using drones as countermeasures. Municipalities that already have coasts have begun operating unmanned multicopters for coastal safety management. In particular, by connecting an unmanned multi-copter to the currently applied smart city safety net system, it is possible to transmit real-time images of the scene in case of emergency in the coastal area to the local government safety information center. It is also expected to contribute significantly to strengthening safety management in coastal waters through a more rapid response to safety accidents. Therefore, in this paper, we propose the use of drones as an alternative to the limitations of the domestic coastal safety system by investigating the state of coastal safety accidents and analyzing the state of domestic coastal safety systems. In addition, it is expected to be a key breakthrough in the coastal area safety system by proposing a model linking the Korean K-Drone system.

Korean firms are faced with the necessity of creating new markets in 21st century. Korean economy has witnessed the accelerated growth rate of trade volume during the period from the latter part of 20th century to the early part of 21st century. In recent times, Korean export volumes have been stagnated. For the second take off, Korea has to create a new ASEAN BOP market. In order to penetrate into the ASEAN BOP Market, it is necessary for exporting firms to have a partnership with ASEAN countries via ODA. In particular, Public-Private Partnership(PPP) might be seen as an effective tool to access the BOP market in ASEAN region. The international development cooperation based on PPP will establish the humanitarian values as well as economic values through the combined effort of government and business enterprises. This study suggests four kinds of business model to have a mutual cooperation between Korean firms and ASEAN markets.

This study was conducted to identify factors influencinging confidence in performing patient safety management (PSM) of nursing students. The subjects of this study were 230 nursing students in four universities in two cities. Data were collected between June 22 and June 26, 2020 using by completing structured self report questionnaires. Data were analyzed using SPSS/WIN 21.0. programs. In correlation analysis, significant positive correlations were found between confidence in performing PSM, PSM knowledge(r=.321, p<.001), PSM attitude(r=.584, p<.001), and clinical decision making ability(𝛽=.460, p<.001). In multiple regression analysis, PSM attitude(𝛽=.35, p=.005) and clinical decision making ability(𝛽=.23, p<.001) were factors predicting confidence in performing PSM, which explained 34.2% of the variance in the model. Therefore, we emphasize that continuing customized convergence educational programs are required to improve nursing student's confidence in performing PSM.
