One of the key features of a mobile crowd-sensing (MCS) system is task allocation, which aims to recruit workers efficiently to carry out the tasks. Due to various constraints of the tasks (such as specific sensor requirement and a probabilistic guarantee of task completion) and workers heterogeneity, the task allocation become challenging. This assignment problem becomes more intractable because of the deadline of the tasks and a lot of possible task completion order or moving path of workers since a worker may perform multiple tasks and need to physically visit the tasks venues to complete the tasks. Therefore, in this paper, a hybrid search algorithm for task allocation called HST is proposed to address the problem, which employ a traveling salesman problem heuristic to find the task completion order. HST is developed based on the tabu search algorithm and exploits the premature convergence avoiding concepts from the genetic algorithm and simulated annealing. The experimental results verify that our proposed scheme outperforms the existing methods while satisfying given constraints.

Purpose: The purpose of this study was to test and validate a model to predict living and brain death organ donation intention in nursing students. The conceptual model was based on the theory planned behavior. Methods: Quota sampling methodology was used to recruit 921 nursing students from all over the country and data collection was done from October 1 to December 20, 2013. Results: The model fit indices for the hypothetical model were suitable for the recommended level. Knowledge, attitude, subjective norm and perceived behavioral control explained 40.2% and 40.1% respectively for both living and brain death organ donation intention. Subjective norm was the most direct influential factor for organ donation intention. Knowledge had significant direct effect on attitude and indirect effect on subjective norm and perceived behavioral control. These effects were higher in brain death organ donation intention than in living donation intention. Conclusion: The overall findings of this study suggest the need to develop systematic education programs to increases knowledge about brain death organ donation. The development, application, and evaluation of intervention programs are required to improve subjective norm.

A recent study suggested that methylation of ubiquitin-like with PHD and RING finger domain 1 (UHRF1) is regulated by SET7 and lysine-specific histone demethylase 1A (LSD1) and is essential for homologous recombination (HR). The study demonstrated that SET7-mediated methylation of UHRF1 promotes polyubiquitination of proliferating cell nuclear antigen (PCNA), inducing HR. However, studies on mediators that interact with and recruit UHRF1 to damaged lesions are needed to elucidate the mechanism of UHRF1 methylation-induced HR. Here, we identified that poly [ADP-ribose] polymerase 1 (PARP1) interacts with damage-induced methylated UHRF1 specifically and mediates UHRF1 to induce HR progression. Furthermore, cooperation of UHRF1-PARP1 is essential for cell viability, suggesting the importance of the interaction of UHRF1-PARP1 for damage tolerance in response to damage. Our data revealed that PARP1 mediates the HR mechanism, which is regulated by UHRF1 methylation. The data also indicated the significant role of PARP1 as a mediator of UHRF1 methylation-correlated HR pathway.

The purpose of this research is to identify effect of communication strategy as effectively communication method which is decreasing Internet Web site users' perceived information privacy concerns as important factor affecting to positive behavior or behavioral intentions on long-term relational outcome perspectives. This study suggests alternatives concepts and causal relationship about information privacy issues. First, it addressed collaborative communication strategy (CCS) model of effective communication method for Web site's IPP to users. Second, it provided comparing and integrating streams of information privacy research on long-term relational outcomes perspective. Third, it assessed effectiveness of Web site's IPP on organization legitimacy ensured continuous survival of organization. A research model was proposed and subsequent hypotheses were empirically tested with partial least square (PLS) based on 684 responses from the users of 21 Internet Website among entirely finance, recruit, portal /e-store Web site. It was learned that CCS(as a communication method) and relationship quality(representing long-term relational outcomes)was positively associated with decreasing user's IPC more than privacy risk. Also, legitimacy to information privacy practice positively associated with willingness to information providing more than negative effect of IPC. Lastly, their association strength was partially moderated by the type of real information sensitivity.

Purpose: The purpose of this study was to investigate the relationship between social support and loneliness in elderly women living alone. Method: Between 1 October 2008 and 30 April 2009, a random sampling method was conducted to recruit 112 elderly women who were living alone. The subjects were at least 65 years of age. Data was collected using the social support questionnaire, and the translated Korean Version of the Revised University of California at Los Angeles Loneliness Scale (R-UCLA Loneliness Scale). Results: In our study, the sources of social support were the children, neighbours, brothers and sisters, in this order. We found that the loneliness of the subjects was related to age, the number of children, and financial difficulty. The level of loneliness negatively correlated with the social support provided by children, brothers and sisters, other relatives, and neighbours. Also, there was a negative correlation with the social support satisfaction. The social support satisfaction and the social support offered by neighbours and relatives were the significant predictors of loneliness. Conclusion: The sources of social support, such as neighbours and relatives, and the social support satisfaction should be considered when planning intervention by nurses or social workers to decrease the level of loneliness in elderly women living alone.

I The Purpose of this study is to look in to the production of high-functional clothing industry, such as item, style, layout, labor, suggest some effective solutions and alternatives for them. 23124554 For this purpose, the companies specialized in manufacturing of special high-functional clothings were sampled for a survey using interview and a questionnaire. The results of this study can be summarized as follows; It was found that since demands for high-functional apparels are low and their sewing processes are much complicated requiring expensive equipments, only a few companies are engaged in such apparels. In addition, since the quantity of order s small and material inputs are more frequently changed, the sewing processes on the production line need to be changed together with the production layouts. On the other hand, as the materials used are very special, expensive equipments should be used, for which the companies feel much burdensome financially. Accordingly, t is deemed necessary for the high-functional apparel manufactures to specialize the processes requiring specialized equipments or outsource some of them or recruit highly-skilled workers.

This project aims to provide information on organizations and characteristics of Korean designer fashion industry in order to improve employment environment in fashion designer brands. This study utilizes the questionnaires and interviews with designers or human resources managers in Korean designer brands for forms, size and way of employment. The result shows that firstly, the size of employment in fashion designer brands is almost operated by small-scale human resources. Secondly, It is researched that they recruit less than 10 temporary employees per a brand on average as a problem. Thirdly, there are differences in business according to forms of employment. As researched, permanent employees usually conduct in design, products plan and production management, but, temporary employees conduct as a business assistant and salespeople. Fourthly, it is revealed that average salaries for permanents in fashion designer brands are between 1,510,000 and 2,000,000 won as the most people said. Moreover, the average salaries for temporaries are similar with permanents' as between 1,170,000 and 1,500,000 won. In fifth, in terms of the ways for recruitment, the proportion of job seekers who find a job by nonscheduled admission and special employment is larger than other ways. Finally, as a result of a research on an employment contract, employees have written the employment contract with the brands.

Lateral giant (LG)-mediated escape response of crayfish is sensitized by natural traumatic events. Such sensitization has previously been shown to be associated with increased transmission between primary afferents and sensory interneurons at the cholinergic synapse of LG escape reflex circuit. In the present study, it was firstly investigated as to whether transmission is also altered at other synapses of the LG-escape reflex circuit by traumatic shock-induced sensitization. Evidence that traumatic shock also directly affects the excitability of lateral giants is now provided by the finding that traumatic shock produces a significant reduction of the time needed for LG to recruit its contralateral homologue, which is defined as commissural delay. Octopamine, a naturally occurring neuromodulator in the crayfish nerve cord, has also been shown to enhance transmission at the cholinergic synapse between primary afferents and sensory interneurons, and has been conjectured to mediate sensitization. Like traumatic shock, $octopamine\;(10^{-5}-5{\times}10^{-4}\;M)$ also enhanced the efficacy of commissural transmission between lateral giants, as indicated by a significant reduction of commissural delay. This effect was blocked by an octopamine antagonist phentolamine, suggesting a specific action of octopamine on the octopamine receptor present on LGs. These observations suggest that both traumatic shocks and octopamine may cause a rather broad alteration in the excitability of the crayfish nervous system that contributes to the sensitization of the LG escape response.
