Syntactic information represents the dependency relation between predicates and arguments, and it is helpful for improving the performance of Semantic Role Labeling systems. However, syntax analysis can cause computational overhead and inherit incorrect syntactic information. To solve this problem, we exclude syntactic information and use only morpheme information to construct Semantic Role Labeling systems. In this study, we propose an end-to-end SRL system that only uses morpheme information with Stacked Bidirectional LSTM-CRFs model by extending the LSTM RNN that is suitable for sequence labeling problem. Our experimental results show that our proposed model has better performance, as compare to other models.

While the survival rate of preterm infants and employment rates of mothers with infants have been dramatically increasing, little is known about the impact of maternal employment and having premature infants on maternal health recovery after delivery. The purpose of this longitudinal study was to examine differences in postpartum health by mother's employment and infant's prematurity over time during the first 3 months postpartum. The study used a longitudinal design and was secondary data analysis from a large study. A convenience sample of 132 mothers was recruited with mothers who had fullterm or preterm infants through the postpartum unit. They were followed up for 3 times (at 1-2 days, 6 weeks, and 3 months) during the first 3 months postpartum period. Level of fatigue and hysical symptoms were indicators for postpartum physical health; Positive affect and negative affect were assessed for postpartum mental health, and role functional status after childbirth was for role performance. Finding indicated that health indicators changed significantly over time but there was no main or interaction effect for maternal employment status. There were main effects of infant's prematurity on positive affect, negative affect, and role functional status (self-care and social and community activities). This study enhanced the understanding of postpartum health of mothers with preterm infants as well as those with fullterm infants during the postpartum period.

For an efficient role based access control in highly distributed computing environment to reduce management cost, we utilize attribute certificates. Especially highly distributed computing environments such as ubiquitous computing environments which cannot have global or broad control, need another attribute certificate management technique. The techniques for transmission of the attribute certificates and management of the group keys should be considered to reduce management cost. For better performance we structure attribute certificates. We group roles and make the role group relation tree. It results secure and efficient role renewing and distribution. For scalable attribute certificate distribution, multicasting packets are used. We take into account the packet loss and quantifying performance enhancements of structuring attribute certificates.

Purpose - Inducing consumers' behavioral intent to use an outlet shopping center is a critical issue for managers since it can be used as a guide for developing marketing strategies. Low prices could lead to a growth in retail purchases, but there might also be a positive relationship between prices and customer perceptions of product quality. The extent to which consumers use price as a predictor of quality may differ according to the availability of important alternative cues such as brand, store name, and identity salience triggered by the store. Consumers can obtain non-economic benefits from marketing exchanges that go beyond basic economic achievement. We argue that identity salience can play a crucial mediating role when consumers, acting as exchange partners, seek to obtain social benefits. This study shows that identity salience could mediate the relationship between identity salience-inducing factors such as multi-finality, prestige and role performance, and consumers' behavioral intent to use an outlet shopping center. Research design, data and methodology - The survey was conducted on college students enrolled in marketing classes. A total of 200 questionnaires were distributed, of which only 194 were returned. After five incomplete questionnaires were excluded, a final sample of 189 was used for empirical analysis. Using a covariance structural analysis in Amos17, we confirmed the fit of the research model and estimated its parameters by using the maximum likelihood method. Results - The results of the hypotheses testing are as follows. First, both identity salience and economic benefits have positive effects on the behavioral intent to use an outlet shopping center. Second, role performance, prestige, and multi-finality have positive effects on identity salience. Finally, the additive analysis of the direct effects of identity salience-inducing factors shows that the role performance, prestige, and multi-finality factors have no direct effects on the behavioral intent to use an outlet shopping center, suggesting that identity salience plays a positive mediating role. Conclusions - This study informs marketers that not only price but shoppers' identity salience directly affects their intent to visit an outlet shopping center. To strengthen shoppers' identity salience, marketers should find ways to help shoppers fulfill their multiple social roles, realize their multiple goals, and achieve prestige. In other words, outlet shopping centers must improve their personal service environment in order to enhance their employees' service quality and assist the execution of multi-finality by minimizing the perceived costs (e.g., travel time, effort) associated with shopping trips, thus making it easier for consumers to combine visits to multiple stores in outlet shopping centers and buy the items required for their consumption goals. Outlet shopping centers must also offer assortments with both breadth and depth in order to help consumers play the social roles their social networks have given them.

To improve the competitiveness of the hospital provides high quality medical services in a hospital coordinator role is emphasized. This study on customer orientation of the role ambiguity in order to identify the impact of degree of customer orientation were analyzed for demographic differences. Dependent variable, customer orientation affects role ambiguity as independent variables, and regression analysis were set. And the control variables are set to support situational factors, customer orientation on the role ambiguity and hierarchical regression analysis was performed. Obtained through empirical results are as follows: First, according to the demographic characteristics of the hospital coordinator customer orientation, the difference between gender and medical subjects are not shown. Age, education, work experience, job title, and the hospital on the pattern of customer orientation has shown a difference. Second, according to the hospital coordinator role ambiguity about its impact on customer orientation analysis can be a role implementation, job implementation, opinion communication in achieving customer orientation was negatively affected. Third, role ambiguity, and customer orientation factors for the moderating effects of organizational support for the role of customer orientation can role implementation, job implementation, opinion communication was a statistically significant. Fourth, the role ambiguity factors and customer orientation for the administrative support for the moderating effect of customer orientation and role implementation is significant, but job implementation, opinion communication were statistically significant. Fifth, the role ambiguity factors and customer support for customer orientation and customer orientation for the moderating effects of role performance and the opinion communication was not statistically significant. However, job implementation was statistically significant. The limitations of this study are as follows: First, role ambiguity, situational factors and support due to limitations of the variable factors that may affect the customer orientation of a number of factors were excluded. So many exogenous variables in the measurement process can affect. Second, the variables measured as problems of self-assessment by the variable measuring the respondent's bias may occur. Third, This study is difficult to generalize. In other words, several areas of the province conducted by the empirical results of the survey as a limit on the overall generalization can follow.

Objectives: The purpose of this study was to evaluate the efficiency of patient and doctor role-play on participatory clinical clerkship by surveying student's satisfaction and assessing the improvement of skill and consultation ability after conducting a role-play in a Korean dermatology department. Methods: In 2013, 79 seniors participated in the clinical clerkship of the dermatology department at the college of Korean medicine. Two students were randomly selected and paired up. After a brief instruction, one student played the role of doctor and the other took the role of patient. After finishing the $1^{st}$ role-play, they swapped roles and conducted a $2^{nd}$ role-play, using another clinical case. When the two role-plays were completed, the students filled in a questionnaire about their satisfaction with the role-play as clinical clerkship. Also, we compared the scores of the $1^{st}$ role-play with those of the $2^{nd}$ role-play measured by a medical resident to assess improvements of students' skill and interview ability. Results: It appears that students' satisfaction with the role-play was quite high, considering that the overall mean score of the questionnaire was 4.30. According to the result of a t-test on 15 assessment questions, the $2^{nd}$ role-play had a higher mean score than the $1^{st}$ role-play in 12 questions, though this difference was not statistically significant. Conclusions: These results demonstrate that role-play is helpful to improve students' satisfaction and clinical performance ability in clinical clerkship. Further research and continuous development are necessary for better clinical clerkship.

FMS is two or more computer controlled units interconnected with automated workhandling equipment and supervised by an executive computer having random scheduling capabilities. The complex nature of a FMS, coupled with the need to maximize its performance, means that such a system can be effectly designed only by iterative computer simulation methods. At the operational level, simulation had a reduced role to evaluate the performance of planned FMS under a variety of operating strategies. This is probably due to the fact that few simulation models are able to access the current status data of the system. This study reviews the role of simulation for design/operation of FMS and suggests an interface scheme for incorporating a simulation package with a FMS operational database. This scheme can be used for reducing the performance gap between design and real operation of a FMS.
