The purpose of this study was to investigate the role of anxiety in mediating the influence of family of origin characteristics on subsequent relationship processes. Using Bowenian theory as a foundation, this study examined the causal relationships among gender, religion, family of origin-fusion, intimacy, intimidation, personal-trait-anxiety, couple open communication and relationship satisfaction. Results of the path analysis indicated that: (a) gender, religion, family of origin-fusion, and family of origin-intimidation were directly related to personal-trait-anxiety, (b) personal-trait-anxiety was directly related to couple open communication and not related to relationship satisfaction, (c) couple open communication was directly related to relationship satisfaction, and (d) family of origin factors were not directly related to couple open communication and relationship satisfaction; rather, as it was expected, indirect associations, through the mediation of anxiety, were found. The results generally support Bowen's intergenerational process theory, which asserts that anxiety is the mediator of the process. Limitations of the current study and suggestions for further research were discussed.

In this paper, designing and implementing multi-communication middleware in multi-thread environmet through event-based synchronization method are proposed for stable data transmission of electronic optical equipment, which requires combining camera and various sensors to process multiple high-speed data. To verify the performance of the implemented communication middleware, image data and sensor data were sent to compare differences in reception-based and transmission-based cycles, and the maximum number of communication possibilities to transmit and process multiple was measured and analyzed. In addition, the proposed communication middleware's performance was verified through experiments such as validating the integrity of the transmitted data and measuring the Round Trip Time.

This paper presents a wide output range, high power efficiency reconfigurable charge pump for driving touch panels with the high resistances. The charge pump is composed of 4-stages and its configuration automatically changes based on the required output voltage level. In order to keep the power efficiency over the wide output voltage range, internal blocks are automatically activated or deactivated by the clock driver in the reconfigurable charge pump minimizing the switching power loss due to the On and Off operations of MOSFET. In addition, the leakage current paths in each mode are blocked to compensate for the variation of power efficiency with respect to the wide output voltage range. This chip is fabricated using $0.18{\mu}m$ BCD process with high power MOSFET options, and the die area is $1870{\mu}m{\times}1430{\mu}m$. The power consumption of the charge pump itself is 79.13 mW when the output power is 415.45 mW at the high voltage mode, while it is 20.097 mW when the output power is 89.903 mW at the low voltage mode. The measured maximum power efficiency is 84.01 %, when the output voltage is from 7.43 V to 12.23 V.

There are limitations to process high bandwidth traffic in B-ISDN with mesh- topology single bus architecture of current mobile communication system. And, it is impossible to import ATM switch using fixed length packet rather than variable length packet. Some implementations are able to process variable length packet, but there are some problems such as pre-processing for synchronization and bit delay. In this paper, we design a concentrator that can manipulate variable length packet without additional pre-process. There is on bit delay for packet starting signal in input interface, So it is more efficient to process packets, such that the concentrator can reduce he processing time as $\ulcornerlog2N\lrcorne＋1$ bit-time rather than N bit-time delay in ordinary concentrator. It is expected that the mobile communication system with partial mesh topology bus adopting the knockout switch architecture can process high bandwidth traffic in B-ISDN.

Technology innovation of digital convergence in recent years of the media sector has produced a series of significant changes in journalist labor. This study analyzes how recent introduction of convergent newsroom changed the nature of journalist labor and what strategy the management used to control journalists within the technologically innovated working condition with case of CBS. As the labor process theory tells us, the analysis found that technological innovation in the newsroom has encouraged a couple of aspects regarding labor process. First, losing control over their own labor journalists have undergone the process of significant deskilling. Second, the management have made a constant effort to introduce ideological and political apparatuses with twofold purposes, effective control over workers on one hand and concealing oppressive labor conditions on the other. The effort generated journalists' acceptance of new news-making routine and their consent on labor-management culture founded upon naive familism, which at last resulted in reinforcement of corporate power and isolation of labor society by separating internal labor market.

Near-threshold computing (NTC) is now regarded as a promising candidate for innovative power reduction, which cannot be achieved with conventional super-threshold computing (STC). However, performance degradation and vulnerability to process variation in the NTC regime are the primary concerns. In this paper, we propose a voltage- and frequency-tuning methodology for mitigating the process-variation-induced problems in NTC-based manycore architectures. To implement the proposed methodology, we build up multiple-voltage multiple-frequency (MVMF) islands and apply a voltage-frequency tuning algorithm based on the critical-path monitoring technique to reduce the effects of process variation and maximize energy efficiency in the post-silicon stage. Experimental results show that the proposed methodology reduces overall power consumption by 8.2-20.0%, compared to existing methods in variation-sensitive NTC environments.

To visualize a strategic plan including resource allocations and standardization schedules, it is important to set priorities among information and communication technologies(ICTs) standardization work areas(SWAs). This ranking process involves decision making process with multiple criteria which results a complex selection problem. In this study, analytic hierarchy process(AHP) is employed and applied to solve this decision making problem. The processes and results are illustrated for an effective strategic plan in standardization decision processes.

This paper presents the minimum-cost network selection scheme which determines the transmission instance in the multi-band maritime communication system, so that the shipment-related real-time information can be transmitted within the maximum allowed period. The transmission instances and the corresponding network selection process are modeled by a Markov Decision Process (MDP), for the channel model in the 2-state Markov chain, which can be solved by stochastic dynamic programming. It derives the minimum-cost network selection rule, which can reduce the network cost significantly as compared with the straight-forward scheme with a periodic transmission.
