  • XML Web Services are a distributed computing component which enables users to use services existing in remote places by using a standardized language called XML. Web Services were developed as the cooperation and business scales between companies as businesses had been widened due to the improvement of internet services. For this reason, enterprise sized Web Services are mainly used at present. But as the number of Internet users has been increased, they became in need of more diverse services, and providing individual Web Services are also being more emphasized. Therefore, an Embedded Web Server for personal Web Services for embedded systems such as cell phones had been implemented in this paper. This paper shows the possibility of building up a small, personal sized Web Services Server not the enterprise sized one by doing real implementation.

  • Context-aware engineering services in ubiquitous environments are emerging as a viable alternative to traditional engineering services. Most of the previous approaches are computer-centered rather than human-centered. In this paper, we present a Ubiquitous and Context-Aware computing Framework for collaborative virtual Engineering $(U-CAF\acute{E})$ services. The proposed approach utilizes BPEL-based (Business Process Execution Language) process templates for engineering service orchestration and choreography and adopts semantic web-based context-awareness for providing human-centered engineering services. The paper discusses how to utilize engineering contexts and share this knowledge in support of collaborative virtual engineering services and service interfaces. The paper also discusses how Web services and JINI (Java Intelligent Network Infrastructure) services are utilized to support engineering service federations and seamless Interactions among persons, devices, and various kinds of engineering services.

  • Service identification and composition is one of the key characteristics for a successful Service-Oriented Computing, being receiving a lot of attention from researchers in recent years. In the Service-Oriented Analysis, the identification of business services has to be preceded before application services are identified. Most approaches addressing the derivation of business services are based on heuristic methods and human experts. The manual identification of business services is highly expensive and ambiguous task, and it may result in the service design with bad quality because of errors and misconception. Although a few of approaches of automatic service identification are proposed, most of them are in focus on technical architectures and application services. In this paper, we propose a model on the automatic identification of business services by horizontal and vertical service alignment using Enterprise Architecture as an ontology. We verify the effectiveness of the proposed model of business services identification through a case study based on Department of Defense Enterprise Architecture.

  • The beginning of Web Services was understood as efficient technology for application integration in the internet, thus it was used to integrating the distributed enterprise applications or the e-business applications between partners. But, recently the usage trend of Web Services is largely spreaded out wireless network applications beyond the internet applications. The main reasons are that Web Services is the international standard of W3C, and Web Services is based on XML that is independent of the specific internal implementations such as platform, programming languages, communications networks etc. Currently Major company of Web Services such as MS, IBM, etc. focus on the research about technology for integrating various devices. In this paper, we define and explain technical issues for adapting web services to ubiquitous Environment.

  • Web services show a rapid evolution and integration to meet the increased users' requirements. Thus, web services undergo updates and may have performance degradation due to undetected faults in the updated versions. Due to these faults, many performances and regression anomalies in web services may occur in real-world scenarios. This paper proposed applying the deep learning model and innovative explainable framework to detect performance and regression anomalies in web services. This study indicated that upper bound and lower bound values in performance metrics provide us with the simple means to detect the performance and regression anomalies in updated versions of web services. The explainable deep learning method enabled us to decide the precise use of deep learning to detect performance and anomalies in web services. The evaluation results of the proposed approach showed us the detection of unusual behavior of web service. The proposed approach is efficient and straightforward in detecting regression anomalies in web services compared with the existing approaches.

  • Recently, the hospitals in Korea has positively changed one way or another. Therefore hospital managers must focus on the nurses' role in terms of consumers' perception of overall image of hospitals and the degree of satisfaction of the consumers. To achieve the purposes, the questionnaire was developed and distributed to 280 people who had a direct experience with nursing services subjected hospitals in Seoul at the time of screening. Among them, 229 responses were turned out to be useful and used for final analysis. The measurement instrument for hospital nursing service quality evaluation was modified from the SERVQUAL model originated from Parasuraman, Zeithaml, and Berry (1988). For data analysis, SPSS/PC and PC-MDS program were used. The results were as follows : 1) The perception map showed that the seven subjected hospitals were divided into three groups. It could be interpreted that the hospitals in the same group had a strong competitive relationships. Because the nursing services' scores of hospitals C and E were higher than those of other hospitals, they could be served as a benchmark for the other hospitals. 2) The marketing place of hospital nursing services was divided by four. Since service generally had a strong point in nearby service market segment. Aiming an nearby hospital nursing services market segment by the hospital nursing services department was regarded as a good repositioning strategy. 3) When consumers evaluated the quality of hospital nursing services, they were greatly affected by the hospitals' overall image or other characteristics. Therefore, for improving hospital's nursing services, hospital nursing services department requires a great deal of labor to improve hospitals' overall image or other characteristics.

  • Service discovery is one of the major challenges in cloud computing environment with a large number of service providers and heterogeneous services. Non-uniform naming conventions, varied types and features of services make cloud service discovery a grueling problem. With the proliferation of cloud services, it has been laborious to find services, especially from Internet-based service repositories. To address this issue, services are crawled and clustered according to their similarity. The clustered services are maintained as a catalogue in which the data published on the cloud provider's website are stored in a standard format. As there is no standard specification and a description language for cloud services, new efficient and intelligent mechanisms to discover cloud services are strongly required and desired. This paper also proposes a key-value representation to describe cloud services in a formal way and to facilitate matching between offered services and demand. Since naïve users prefer to have a query in natural language, semantic approaches are used to close the gap between the ambiguous user requirements and the service specifications. Experimental evaluation measured in terms of precision and recall of retrieved services shows that the proposed approach outperforms existing methods.

  • The purpose of this paper is deriving philosophical foundations of information services by clarifying its concepts and attributes. Clarifying its concepts and attributes is based on the origin of the term information services, definitions and contents, historical and social perspectives. The theory of information services was reorganized by logically demonstrating that the term "information services" is most suitable name to represent its essence, attributes, and activities. The philosophy of information services has the key elements as instruction, information, guidance, and service in humanistic aspects which have been shown consistently in the origin of the term, definitions, historical and social perspectives. This paper tried to establish philosophical basis for information services that is focused on these elements.

  • All the factors related in education of Korea are very important in the aspect of economic development. The numbers of students being in school from kindergarten through university approximate a quoter of Korean people. Nevertheless paradigm of commercialism in education has been excluded completely in discussion by the reason of 'educational objective' of education fields in Korea. So Korea's educational services have been confronted with various problems which could hardly be solved, and have lost global competitiveness with the development of globalization. The purpose of this paper is to examine the commercialism of educational services by analysing various social phenomena and government policies relating to educational services in Korea, and to find some alternatives which are able to introduce commercialism on educational fields in Korea. Methodology of this paper depends on the theoretical analysis. Major findings of this study can be summarized as follows: First, notwithstanding that the relative importance of education is the same to that of economy in Korea, the providers of educational services in Korea are against their commercialism problems. Second, it is suggested that the stereotyped idea, that is, the commercialism in educational services be excluded, should be removed above all. Third, in order to improve the competitiveness of educational services in Korea, it is recommended that the commercialism be recognized in a part and various strategies such as the s-SCM, educational service marketing, etc. be introduced. Fourth, we have to prepare for globalization of educational services through making the educational industry to exporting services.

  • The present study aimed to examine the influences of four aspects of family friendliness (i. e., safety, accessibility, convenience, and amenity) and diversity of services designed to support children's development and parenting on parental satisfaction with services. The participants of this study comprised 259 parents (214 mothers and 45 fathers) who had at least one child aged 0 to 11 and lived in Seoul, Gyeonggi-do, Chungcheong-do, or Gyeongsang-do Provinces. The data were analyzed by means of descriptive statistics and multiple regression analyses. Our results indicated that the effects of family friendliness and diversity of services on parental service satisfaction differed by children's developmental level. For parents of elementary school-aged children, the safer the services and the more services they used, the more they were likely to be satisfied with the services provided. In contrast, the safety and the amenity of services had positive influences on parental satisfaction with support services for parents with toddlers while the safety had a significant effect for those who had preschoolers.
