This paper is aimed to introduce the practical case about the operation system consisted of academic curriculum and portal system for the IPP implementation. After benchmarking the preceding universities system, the academic program is renewed for our student's participation without difficulty with semi-quater semester system. The portal system is designed to focus on the studentindustry matching and the adaptation to disparate databases of the university. The IPP operation system have been constructed to fulfill the 1st-year-plan as a participating university in 4th period support of Korean government. The first year project performance with constructed system indicated that in many categories of the survey conducted by the IPP management institution, the satisfaction level in that system exceeded the average value of the IPP participating universities nationwide. The improvement direction was set after analyzing the results of the survey.

In non-orthogonal multiple access (NOMA), the degraded performance of the weaker channel gain user is a problem. In this paper, we propose the asymmetric binary pulse amplitude modulation (2PAM), to improve the bit-error rate (BER) performance of the weaker channel user in NOMA with the tolerable BER loss of the stronger channel user. First, we design the asymmetric 2PAM, calculate the total allocated power, and derive the closed-form expression for the BER of the proposed scheme. Then it is shown that the BER of the weaker channel user improves, with the small BER loss of the stronger channel user. The superiority of the proposed scheme is also validated by demonstating that the signal-to-noise ratio (SNR) gain of the weaker channel user is about 10 dB, with the SNR loss of 3 dB of the stronger channel user. In result, the asymmetric 2PAM could be considered in NOMA of 5G systems. As a direction of the future research, it would be meaningful to analyze the achievable data rate for the propsed scheme.

In order to obtain the overall fire line information of medium and large forest fires at night, the ground control system was developed to determine whether forest fires occurred through real-time video clips and to calculate the location of the forest fires determined using the location of drones, angle information of video cameras, and altitude information on the map to reduce the time required for regular video matches obtained after the completion of the mission. To verify the reliability of the developed function, the error distance of the aiming position information of the flight altitude star and the image camera was measured, and the location information within the reliable range was displayed on the map. As the function developed in this paper allows real-time identification of multiple locations of forest fires, it is expected that overall fire line information for the establishment of forest fire extinguishing measures will be obtained more quickly.

The purpose of this study was to determine the associations among emotional burnout, resilience, job embeddedness, and organizational commitment, provide basic data for an effective dental care delivery system and manpower management, and promote organizational commitment in clinical dental hygienists. For data collection, convenience sampling was performed among dental hygienists working in Daejeon and Chungcheong and Jeolla Provinces from November 11 to December 30, 2019, and a self-administered questionnaire was used. Organizational commitment was positively correlated with resilience and job embeddedness and was negatively correlated with emotional burnout; emotional burnout was negatively correlated with resilience and job embeddedness; and resilience was positively correlated with job embeddedness. The factor most significantly affecting organizational commitment was emotional burnout, followed by resilience and job embeddedness. It is therefore necessary to give another consideration to a customized intervention strategy, which involves emotional burnout, resilience, and job embeddedness, in exploring a program that helps clinical dental hygienists maintain and manage organizational commitment efficiently.

The purpose of this study is to analyze the facilitating and conflicting factors on the emerging technologies and trends predicted to impact future education in Korea. To do this, open online questionnaires on 20 emerging technologies and trends derived from a comprehensive literature review were completed by 24 experts in research, policy, schools, and corporate fields, and a content analysis of the collected qualitative data was conducted. As a result of the study, the effectiveness of the content and the maturity of technology were found to be the most important facilitating factors and obstacles. In addition, the potential for innovative teaching and learning methods and motivation, and the maturity and popularity of technology were found to be the main facilitating factors. On the other hand, health problems and negative effects on students in ethical aspects, the lack of research and development, and poor networks and infrastructures in terms of education environment were found to be the main impeding factors of emerging technologies and trends.

Distribution channels are changing its industry paradigm from quantitative increase to qualitative improvement. In addition, it incorporates new characteristics and consumption tread of customers and the core value of service is developing focused around on online to offline (O2O) business model of omnichannel. In this respect, companies are integrating various distribution channels and in order to provide high content business service to customers, their interest in finding a new business strategy is increasing. Currently, most of the service being provided to customers are formed based on distribution structure centered around big companies and financial industry and the problems faced by small to medium and micro enterprises, which are expansion and improvement of channels, discovery of new distribution channels and finding O2O marketing strategy, can be said as very important task. Accordingly, this research purports to create added values which can serve as the driving force of growth of "creative economy" by improving distribution channels in which anyone who incorporates needs of smart consumers can enter into the smart commerce market and to further form sustainable win-win market that is strategic through business platforms for small to medium and micro enterprises therefrom.

Many studies have been carried out for the development of big data utilization and analysis technology recently. There is a tendency that government agencies and companies to introduce a Hadoop of a processing platform for analyzing big data is increasing gradually. Increased interest with respect to the processing and analysis of these big data collection technology of data has become a major issue in parallel to it. However, study of the collection technology as compared to the study of data analysis techniques, it is insignificant situation. Therefore, in this paper, to build on the Hadoop cluster is a big data analysis platform, through the Apache sqoop, stylized from relational databases, to collect the data. In addition, to provide a sensor through the Apache flume, a system to collect on the basis of the data file of the Web application, the non-structured data such as log files to stream. The collection of data through these convergence would be able to utilize as a basic material of big data analysis.
