The bit walk-off effect caused by fiber dispersion and carrier reuse in the base station (BS) are two key problems in radio-over-fiber (ROF) systems. In this paper, a novel frequency-octupling ROF system based on the Mach-Zehnder modulator (MZM) is proposed, which can overcome the bit walk-off effect and realize carrier reuse by inserting pilot signals. Theoretical analysis and simulation verification of the system are carried out. Under the condition of a Q factor greater than 6, the optical fiber transmission distance of the upper and lower links is more than 290 km and 80 km, respectively. The influence of the main device parameters of the system on the Q factor is analyzed when they deviate from their designed values. The system designed in this paper can not only effectively overcome the bit walk-off effect, but also solve the problem of downlink performance degradation and the limitation of tunability caused by conventional carrier reuse in ROF. The system can greatly increase the transmission distance and improve the performance of the system and has an important application prospect in ROF.

This study tried to confirm the mediating effect of positive psychological capital on the relationship between the communication Competence of managers who are recognized as organizational members working in the company and the adaptive performance of the members. To this end, the research hypothesis established through the final 255 data was verified as follows using the SPSS 21.00 and AMOS 21.1 version statistical programs. First, the higher the manager's communication Competence, the higher the positive psychological capital of organizational members. Second, the higher the communication Competence of the manager, the higher the adaptive performance of the members. Third, as the positive psychological capital of organizational members improved, adaptation performance improved. Fourth, positive psychological capital showed a partial mediating effect between the manager's communication Competence and the member's adaptive performance. The results of this study empirically analyzed the relationship between manager's communication Competence and members' positive psychological capital assumption (+) on the improvement of organizational members' adaptive performance ability. This study has the meaning of the most important research in that it provides additional theoretical and practical implications in the face of insufficient research on factors affecting the adaptation performance of organizational members.

This study confirmed the effect of manager's communication type perceived by organizational members on innovative behavior and the mediating effect of organizational culture. In other words, the manager's communication type was statistically positive for organizational members' innovation behavior (Hypothesis 1) and organizational culture (Hypothesis 2). Organizational culture improved innovative behavior of organizational members (Hypothesis 3). In addition, organizational culture played a mediating role between the manager's communication type and organizational members' innovative behavior (Hypothesis 4). In other words, the importance of improving the innovative behavior of organizational members, which is a key factor for advancing organizational sustainability management, was confirmed. It was confirmed that the manager's communication type and organizational culture act as a key factor for the advancement of innovative behavior. Therefore, executives and managers confirmed the importance of systematic managers' communication-type competency development and organizational culture revitalization plans and the necessity of implementing them in order to improve innovative behavior.

In this paper the effect of instability and chaos in optical fiber networks based on the Internet is described. Nonlinear optical fiber effect especially Brillouin scattering in networks has emerged as the essential means for the construction of active optical devices used for all-optic in-line switching, channel selection, amplification, oscillation in optical communications and a host of other applications. The inherent optical feedback by the back-scattered Stokes wave in optical networks also leads to instabilities in the form of optical chaos. This paradigm of optical chaos in fiber Internet serves as a test for fundamental study of chaos and its suppression and exploitation in practical application in optical fiber communication. This paper attempts to present a survey and some of our research findings on the nature of Brillouin chaotic effect on Internet based optical communication.

Purpose: This study was conducted to compare the level of depression, self-esteem and mother-adolescent (M-A) communication perceived by both mothers and adolescents between the early adolescent (E-A) group and the late adolescent (L-A) group; and to examine the actor effect and the partner effect of self-esteem and M-A communication on depression in mothers and adolescents. Methods: Participants were 107 Kirogi families who resided in the Midwest region of the U. S. Data were collected from September, 2008 to March, 2009 using the scales of Center for Epidemiologic Studies Depression (CES-D), Self-esteem and Parent-Adolescent Communication Inventory. Results: Mothers in E-A group reported higher scores on depression than mothers in L-A group. Adolescents in L-A group reported higher scores on depression and lower scores on self-esteem than adolescents in E-A group. In the E-A group, mothers' selfesteem had big actor effect on mothers' depression and partner effect on adolescents' depression. In the L-A group, selfesteem of mothers and adolescents had actor effect on their depression respectively without partner effect. M-A communication of mothers influences mothers' depression negatively and adolescents' depression positively. In both group, M-A communication influences their depression with mediating effect of self-esteem. Conclusion: To promote Kirogi families' mental health, programs for mothers and adolescents should be developed differently according to adolescents' development stage.
