  • 6LoWPAN based on IEEE 802.15.4 is a realistic standard platform for various Internet of Things (IoT) applications. To bootstrap the LoWPAN (Low-power Wireless Personal Area Network), each device must perform 6LoWPAN-ND address registration to assign a unique IPv6 address. Without adequate security mechanisms, 6LoWPAN-ND is vulnerable to a variety of security attacks including corrupted node attacks. Several security mechanisms have been proposed as a supplement to the vulnerability, but the vulnerability exists because it relies solely on IEEE 802.15.4 hop-by-hop security. In this paper, we propose and analyze a vulnerability of 6LoWPAN-ND address registration and a new security mechanism suitable for preventing the attack of damaged node. It also shows that the proposed security mechanism is compatible with the Internet Engineering Task Force (IETF) standard and is more efficient than the mechanism proposed in the IETF 6 lo WG.

The subjects are 508 female workers with disabilities who participated in the 1st wave of the Panel Survey of Employment for the Disabled in Years7-8 (2014-2015). A multiple regression analysis was conducted, and the mediation effect was verified according to the research procedures of Baron and Kenny(1986) using bootstrapping. The results showed that organizational justice and work environment stress faced by female workers with disabilities had a negative impact on organizational commitment, and communication and interpersonal relations had a partial mediation effect. Based on these results, this study suggested ways to reduce job stress and increase organizational commitment of female workers with disabilities.

  • This study aims to examine whether a parental neglect affects an adolescent's peer attachment and adult media immersion has a mediating effect. To achieve this goal, the first year of middle school panel of 'the 6th(2015) Korean Children and Youth Panel Survey(KCYPS)' was utilized. Using SPSS PROCESS Macro developed by Hayes, 'Bootstrapping' was employed to examine the significancy of the mediating effect on 563 objectives. According to the study, first of all, more parental neglect gave rise to less peer attachment. Second, the adult media immersion partly mediates the parental neglect and the adolescent's peer attachment. The practical implications of this results are below : First, parents' care and affection inside a home is necessary to formulate the healthy peer attachment of adolescent. Second, a parent education is important to prevent an adolescent's adult media immersion. Third, an adult media education for an adolescent is desired.

  • The purpose of this study is to verify empirically the effects of BJ worship and perceived homophily on game efficacy through mediating effect of loyalty to viewing. 485 participants who had watched personal game broadcasting were collected as a sample through an online survey and the collected data were analyzed through structural equation modeling. The research model assuming full mediating effect and the alternative model assuming partial mediating effect were compared and bootstrapping was performed to analyze direct and indirect effects between variables. The results showed BJ worship and perceived homophily had significant effects on game efficacy through the full mediated effect of loyalty to viewing. The noteworthy contribution of this study is to verify how viewing personal game broadcasting has a significant impact on the formation of game efficacy and then ultimately provide positive perception of BJ.
