In order to verify that the ego-resiliency regulates the effect of nursing care workers job stress on the job satisfaction, this research ascertained the effect of job stress of the nursing care workers working at Seoul-type Day Care Center and confirmed the moderating effect of ego-resiliency on the process where nursing care workers job stress affects the job satisfaction. A survey of 256 employees at 28 Seoul-type Day Care Centers were conducted on job stress, job satisfaction, and ego-resiliency, and 138 nursing care workers were analyzed. The data analysis was conducted using SPSS PROCESS Macro, which was presented by SPSS 25.0 and Hayes. The results of the study are as follows. First, nursing care workers had higher job stress and lower job satisfaction compared to other job groups. Second, job stress identified the negative effect job satisfaction. Third, ego-resiliency confirmed positive moderating effect between job stress and job satisfaction.

This paper discusses the possibility of enhancing the efficiency in Second Language Learning with the help of an educational information and content search system that utilizes a Cloud system based Big Data. The proposed system plays a role in tracing the exact information that user request considering the interest, level, and aptitude of each individual. Also, the system screen outs unnecessary learning materials if they do not correspond to the user level which in result is one of the key factor in the proposed system. Since it requires multiple steps of verification in providing the extracted results finding out a way to reduce the steps to shorten the time of process.

Web services are considered as the critical component in the business plans of corporations as they offers the potential for creating highly dynamic and versatile distributed applications that span across business boundaries. Web Service Orchestration studies composition of already-existing web services to create new value-added services. The composite web services could be executed in a centralized or peer-to-peer(P2P) orchestration model. Compared with centralized-orchestration model, the P2P-based orchestration model provides better scalability, reliability, and performance for the overall services. However, recent P2P-orchestration solutions have limitation in supporting complex workflow patterns. Therefore, they could not effectively handle sophisticated business workflow, which contains complex workflow patterns. In this paper, we propose the WORKGLOW system, which can deal with complex workflow patterns while it is able to perform composite services in P2P orchestration manner. Comparing with centralized orchestration systems, the WORKGLOW brings up more business logic advantages, better performance, and higher flexibility with only a little overhead.

This study is concerned with the effect of a brand symbol of a family restaurant on brand image, preference, and purchasing intention. With regard to analysis methods, the study carried out a reliability test and a validity test concerning a precedent research concept, ahead of verifying the hypothesis by using the SPSS Ver. 16.0. Also, the study conducted a frequency analysis, technical analysis, exploratory factor analysis, and regression analysis for verifying the hypothesis. As a result of the research, regarding a brand symbol as a visual symbol, three factors including a functional factor, a value factor, and an aesthetic factor were extracted, and of them, the functional factor and an aesthetic factor were discovered to influence of the brand image and preference which affected purchasing intention. In addition, consumers preferred a logo type that includes a company name or a brand name rather than a picture or a mark type of a symbol regarding a brand symbol, and they answered that outdoor advertising would raise awareness more than TV advertising.

Various applications are widely developed for smartphones to meet customer's needs. In many companies, messenger's typed interactive systems have been studied for business marketing, advertising and promotion to provide useful services for the customers. Such interactive systems are usually called as "Chatbot". In Chatbot, duplicated responses from Chatbot could occur frequently, and these make one lose interest. In this paper, we define a case that the response of Chatbot is duplicated according to the user's input, and propose a method to reduce duplicated responses of Chatbot. In the proposed method, we try to reduce duplication responses through a new duplication avoidance algorithm by building multiple tables in a database and by making combinations of user's input and its response in each table. In our experiments, the proposed method shows that duplicated responses are reduced by an average of 70%, compared with the existing method.

With ubiquitous computing and network, the concern of government, business and academy for IT or ICT convergence has been increased. In this paper, through the analysis of keyword trend for ICT convergence services from 2000's mid, the efficient policy is proposed by estimating the understanding and concern of common people. In addition to, the concept and development step of convergence are analyzed, and the keyword analysis for the ICT convergence services defined in TTA is performed. The services are classified into smart home work transportation, Health ICT, RFID USN, M2M IoT, e-Navigation, intelligent robot, and the keywords for each service are analyzed. The analytic results indicate that the keyword trend varies in the time, and highly indexing keywords and new trend are defined. To provide the efficient ICT services, the new ICT convergence services needed for customer will be proposed with new IT technology development, IT standard, law management, and policy provisioining.
