Sign language is a natural, visually oriented and non-verbal communication channel between people that facilitates communication through facial/bodily expressions, postures and a set of gestures. It is basically used for communication with people who are deaf or hard of hearing. In order to understand such communication quickly and accurately, the design of a successful sign language translation system is considered in this paper. The proposed system includes object detection and classification stages. Firstly, Single Shot Multi Box Detection (SSD) architecture is utilized for hand detection, then a deep learning structure based on the Inception v3 plus Support Vector Machine (SVM) that combines feature extraction and classification stages is proposed to constructively translate the detected hand gestures. A sign language fingerspelling dataset is used for the design of the proposed model. The obtained results and comparative analysis demonstrate the efficiency of using the proposed hybrid structure in sign language translation.

Service organizations increasingly adopt data-based intelligent engines called chatbots in support of the interaction between customers and the companies. Two different types of chatbots have been suggested and introduced by companies leading the adoption of this emerging technology: rule-based chatbots and natural language processing-based chatbots. While the differences between these two types of technologies look relatively clear, the organizational and practical impacts of the differences have not been systematically explored. This study performed an experiment to compare the use of the two different types of chatbots used in practice by two comparable organizations. These two types of actual chatbots were used by Korean on-line shopping malls with similar business models (mobile shopping), length of history, size and reputation. The comparison was made based on such dimensions as usability, searchability, reliability and attractiveness. Contraty to conventional expectation that the superiority in technology will produce superior usability, the results show mixed superiority. The discussion on the reasons is presented.

The purpose of study is to examine the effects of family support on the life satisfaction of elderly with disabilities and provide a ground necessary to improve it. Research was conducted on 167 elderly with hearing, visual and physical disabilities aged over 60 who were living in Seoul and Pusan. Telephone survey, sign language and interview, in accordance with types of disability, were adopted to collect data effectively. That is telephone survey was used for elderly with visual impairment whereas face-to-face interview for physical impairment and sign language for hearing impairment by volunteers. Collected data were analyzed, using hierarchical regression analysis. This study utilized two different models, direct effect model and buffering effect of social support in order to examine the effects of familial support on the life satisfaction of elderly with disabilities. Research findings suggest that the level of life satisfaction appeared to be low in general among elderly with disabilities and emotional family support exerted a positive effect on life satisfaction. In addition, it is empirically supported that emotional family support buffered the negative effect of economic limitations on life satisfaction. In other words, the effects of economic limitations as stress factor decreased with the increase in the frequency of emotional support, however, the level of life satisfaction decreased at a mercy of the stress factor of economic limitations with the decrease in the frequency of emotional support. Finally, this paper attempted to provide some alternatives to effectively improve life satisfaction among elderly with disabilities based on empirical findings.

As a part of ebXML(Electronic Business using eXtensible Markup Language) framework, BPSS(Business Process Specification Schema) has been provided to support the direct specification of the set of elements required to configure a runtime system in order to execute a set of ebXML business transactions. The BPS,' is available in two stand-alone representations, a UML version and an XML version. Due to the limitations of UML notations and XML syntax, however, current ebXML BPSS specification fails to specify formal semantic constraints completely. In this study, we propose a constraint classification scheme for the BPSS specification and describe how to formally represent those semantic constraints using OCL(Object Constraint Language). As a way to validate p Business Process Specification(BPS) with the formal semantic constraints, we suggest a rule-based approach to represent the formal constraints and demonstrate its detailed mechanism for applying the rule-based constraints to the BPS with a prototype implementation.

In traditional approach, enterprise-wide consistent security policy enforcement for applications is very difficult task. Therefore, industry is now moving towards new unified enterprise application security concept that consist of centralized authentication and authorization mechanism. The eXtensible Access Control Markup Language (XACML); an XML-based standard defined by OASIS, is most suitable choice which can support centralized, role based, context aware access control mechanism. It is designed to provide universal standard for writing authorization policies and access control request/response language for managing access to the resources. This paper includes a brief overview on XACML and discusses its benefits, limitations and a data flow process. We propose a new generic access control architecture that supports enterprise wide centralized application level access control mechanism using XACML. The other benefits which can be achieved through this architecture are, reduce adnministration cost and complexity, support of heterogeneous computing platforms, centralized monitoring system, automatic fail over, scalability and availability, open standard based solution and secure communication.

As a fundamental knowledge source in a global learning environment, it is feasible to apply the relational database management systems (RDBMS), object-oriented database management systems (OODBMS), and other traditional DBMS. However, the traditional DBMSs are not feasible in semantic knowledge/ontology representation and inference. One of the reasonable ways to overcome the limitations is the semantic web-based business support framework. Especially, in this study, we focused on the development of semantic web ontology and natural language (NL)-based inference framework. To validate the efficiency of the proposed framework, we considered a reasonable scenario for course recommendation in a university.

Purpose: To support implementation of comprehensive, person-centered healthcare, this study aimed to explore immigrant women's public health center (PHC) service experiences and needs while considering Photovoice's feasibility for this purpose. Methods: This qualitative study included 15 marriage-based immigrant women. Participants were recruited from churches and multicultural family support centers using purposive and snowball sampling. Data were collected through four focus group interviews and were subjected to inductive content analysis. Results: Five categories of experiences were identified: language barriers, hectic environment, affordable and practical primary healthcare, feeling ignored and discriminated against, and feeling frustrated. In addition, five categories of needs were identified: language assistance services, ease of access, healthcare across the lifespan, expansion of affordable healthcare, and being accepted as they are. This study provides preliminary evidence that the Photovoice approach can facilitate the interview process in a qualitative inquiry involving participants with limited ability to express their perspectives in the researchers' language. Conclusion: Study findings highlight the need to implement institutional policy and procedural changes within PHCs and to provide culturally competent, personcentered care for South Korea's marriage-based immigrant women and other ethnic minority populations. The findings also provide evidence-based direction for PHC service planning.

The purpose of this study is to examine the factors that are associated with a child's development within a multi-cultural family, taking into account the factors that influence the child's language ability and their play interactions with their mothers. First, there was no significant difference in the children's language ability based on the child's gender, or based on the language in which the mother communicated with her children. However there were significant differences depending on the children's age, the mother's native country, and the period of time the mother had lived in Korea. Second, there was no significant difference in the child-mother play interaction based on the children's age, gender, the mother's native country, the period of time the mother has lived in Korea, or the language in which the mother communicated with her children. However, the boys showed a more hostile attitude toward their mothers, in comparison to the girls. In conclusion, it can be said that there is an urgent need for comprehensive social support services and policies for the overall development of multi-cultural children, especially through programs for children and mothers.
