Device-to-device (D2D) communications underlaid cellular infrastructure is an competitive local area services technology to promote spectrum usage for next generation cellular networks. These potential can only be tap through efficient interference coordination. Previous works only concentrated on interference from D2D pairs whiles interference from CUs to D2D pairs were neglected. This work focus on solving uplink interference problem emanating from multiple CUs sharing its resource with multiple D2D pairs. The base station (BS) acting as a supervisor selfishly institute a pricing scheme to manage the interference it experience from D2D pairs based on its Quality of service (QoS) requirement. D2D pairs following the supervisor make power allocation decisions considering the price from the BS in a non-cooperative game fashion. In order for the D2D pairs to also meet their QoS requirement, they suggest a price to the BS called discount price which reflects the interference they receive from the CUs. Finally, we analyze the proposed approach.

Objectives: The purpose of this study is to identify the general characteristics of manufacturing workplaces and the characteristics of safety and health organizations, and to determine the impact of safety and health-related communication within these organizations mediated by supervisory safety and health management personnel. Methods: This study is based on the Korea Occupational Safety and Health Agency's 2018 Occupational Safety and Health data targeting 1,486 manufacturing sites. Data were analyzed using descriptive statistics, t-test and ANOVA, and mediator variable regression analysis using SPSS 25.0. Results: The average score on communication levels related to safety and health was 11.20 out of 15. The average score of the safety and health management level was 31.04 out of 40. As a result of mediation regression analysis, it was found that safety and health-related communication had an effect on the safety and health management level (𝛽=0.434), and the number of safety and health supervisors was found to mediate the effect of this variable (𝛽=0.069). Conclusions: The level of safety and health-related communication affects the level of health and safety management, and the number of supervisors mediates this influence. Therefore, the role of the supervisor is important in safety and health communication. It is expected that the level of safety and health management can be improved through management and supervisors.

Purpose: The purpose of this research was to delineate the effects of organizational injustice on negative behaviors of employees with the mediating effects of trust. Methods: A survey was conducted among 550 nurses in 11 departments of 3 hospitals located in the Pohang area. Data were analyzed using frequency, descriptive statistics. correlation coefficients, regression analysis. Results: Procedural injustice (${\beta}$=-.48, p<.001) had the greatest negative effect on organizational trust, followed by interactional injustice(${\beta}$=-.15, p<.001) and distributive injustice(${\beta}$=-.14, p<.001). For supervisor trust, both procedural (${\beta}$=-.11, p=.006) and interactional (${\beta}$=-.63, p<.001) injustice had a negative effect. While supervisor trust (${\beta}$=-.28, p<.001) had greater negative effects on organizational negative behaviors of nurses compared to organizational trust (${\beta}$=-.21, p<.001), supervisor trust (${\beta}$=-.29, p<.001) had negative effects on personal negative behaviors but organizational trust had no significant effect on personal negative behaviors. Conclusion: To reduce the negative organizational behaviors of nurses, an organizational effort is needed to reduce procedural injustice by introducing fair organizational management and to reduce interactional injustice through formal or informal communication channels between supervisors and nurses.

악성코드는 탐지 프로그램을 피해 기기들에게 피해를 유발한다. 기존의 악성코드 탐지 기법으로 이러한 새로운 악성코드를 탐지하는데 어려움을 겪는 이유는 서명 기반의 탐지 기법을 사용하기 때문이다. 이 기법은 기존 악성코드들은 효과적으로 탐지하지만, 새로운 악성코드에 대해서는 탐지가 어렵다. 이러한 문제점을 인식하여, 휴리스틱 기법을 추가적으로 사용한다. 이 논문에서는 딥러닝을 활용하여 악성코드를 탐지하는 기술에 대해 소개하여 새로운 악성코드를 탐지하는 기술에 대해서 제안한다. 또한, 악성코드를 탐지한다는 것은, 기기에서 실행 가능한 파일의 개수는 무수히 많으므로, 지도학습 방식(Supervisor Learning)으로는 분명한 한계가 존재한다. 그렇기 때문에, 준지도 학습으로 알려진 SCAE(Stacked Convolution AutoEncoder)를 활용한다, 파일들의 바이트 정보들을 추출하여, 이미지화를 진행하고, 이 이미지들을 학습을 시켜, 학습 시키지 않은 10,869개의 악성코드, 3,442개의 비악성코드를 모델에 추론한 결과 정확도를 98.84%을 달성하였다.

The school library plays very important and central role for the fullfillment of educational objective in the process of implementing the school curriculum. And the media specialist known as teacher-librarian is. primarily responsible for the successful operation and effective management of the media center. It is true that effectiveness of the school library depends greatly on the cooperative coordination among teacher-librarian, teacher and principal in addition to the strong support and effective supervision of school district authority, specifically, supervisor of school library program. The successful program therefore is influenced by their perception of the teacher-librarian's role. The purpose of this study was to investigate the teacher-librarian's. educational role perceived by teacher-librarian, teacher, principal and school district supervisor. A standard task model describing both the management and educational functions and expectations of teacher-librarian was proposed after studying the relevant current standards of four countries. Serveral hypotheses were made regarding role perception and a survey instrument was designed based on this proposed task model and the results of the literature review to validate the hypotheses. The questionnaires were mailed out and the returned questionaires were analyzed by SPSS computer routine. The major findings are summarized as follows: 1) There was difference of the role perception among teacher-librarian, teacher, principal and district supervisor at the significance level of p<0.001 for both management and educational functions of teacher­librarian. The mean score of the teacher-librarian was highest among four groups and the score for the educational function tasks were lower than that of management function tasks. 2) The positive correlation exists at the significance level of p<0.001 between the role perception and the attitude toward changing social trends such as acceptance of new technology, need for better communication and information. 3) The positive correlation exists at the significance level of p<0.001 between the role perception and the view on the curriculum and teaching method.

Communication in real-time distributed system should have high reliability. To develop group communication Protocol with high reliability, potential fault should be known and when fault occurs, it should be detected and a necessary action should be taken. Existing detection method by Ack and Time-out is not proper for real time system due to load to Ack which is not received. Therefore, group communication messages from real-time distributed processing systems should be communicated to all receiving processors or ignored by the message itself. This paper can make be sure of transmission of reliable message and deadline by suggesting and experimenting fault detection technique applicable in the real time distributed system based on ring, and analyzing its results. The experiment showed that the shorter the cycle of the heartbeat signal, the shorter the time to propagate the fault detection, which is the time for other nodes to detect the failure of the node.
