Recently, office workers are increasingly aware of the right to disconnect because of the pressure from strong connections with Internet messengers. In this study, we examined the reason why the perception of the right to disconnect increases and how to deal with it. This research model is that smart working and psychological attachment from work affect right to disconnect, and that open communication and gender moderate the intensity of these effects. To verify this research model, survey questionnaires were distributed to workers in smart working environments, and 400 data were collected and analyzed using Smart-PLS. As results of data analysis, it was verified that smart working and psychological attachment from work had a significant influence on right to disconnect, that open communication group had a lesser effect of psychological attachment from work on right to disconnect than closed communication group, and that women had a lesser effect of psychological attachment from work on right to disconnect than men. Organizations need to maintain a desirable level of right to disconnect in order to improve the quality of working life. But, if it is impossible, They need to change the way of communication more openly so as to absorb the burden of strong connection by Internet. And they need to perform task assignment or stress relief policy reflecting gender characteristics.

Recently, organizational workers are complaining of stress due to excessive connection on SNS and are claiming the right to disconnect. If these claims are not properly managed, organizational performance may deteriorate. Therefore, organizations need to approach the issue of the right to disconnect carefully. This study examined the effects of work connection at office, IT hyper-connected environments, and work connection at home on the right to disconnect, and analyzed the effect of this perception on job satisfaction, and then analyzed gender differences in these effects. The research results are as follows. First, it was found that the work connection at office lowered the right to disconnect. Second, the deeper IT hyper-connected environment, the higher the right to disconnect. Third, it was found that the work connection at home raises the right to disconnect. Fourth, it was found that the right to disconnect increases job satisfaction to a certain extent, but lowers job satisfaction when it exceeds the appropriate line. Fifth, in the case of men, the effect of the right to disconnect on job satisfaction has sharply increased and sharply reduced. On the other hand, in women, it gradually increased and then decreased slowly. Considering the results of these studies, organizations need to check the current status and appropriate level of the work connection at home for organizational performance management. Organizations need to formulate organizational management measures that take into account the positive and negative functions of the right to disconnect. And organizations need to come up with management measures that take gender into account.

A high speed Viterbi decoder with a circularly connected 2-dimensional analog processing ceil array Is proposed. The proposed Viterbi .decoder has a 2-dimensional parallel processing structure in which an analog processing cell is placed at each node of a trellis diagram, the output column of the analog processing cells is connected to the decoding column, and thus, the output(last) column becomes a column right before the decoding(first) column. The reference input signal given at a decoding column is propagated to the whole network while Its magnitude is reduced by the amount of a error metric on each branch. The circuit-based decoding is done by adding a trigger signals of same magnitudes to disconnect the path corresponding to logic 0 (or 1) and by observing its effect at an output column (the former column of the decoding column). The proposed Viterbi decoder has advantages in that it is operated with better performance of error correction, has a shorter latency and requires no path memories. The performance of error correction with the proposed Viterbi decoder is tested via the software simulation.
