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.

이 논문은 지역적 동사구 분할에 바탕을 두고 서술어가 문말에 위치하는 언어에 특성에서 기인하는 속성을 반영하는 부분적 그러나 빠른 구문분석에 관해 논한다. 즉 완벽성 보다는 신속함 그리고 신뢰에 바탕을 둔 새로운 한국어 구문분석에 대해 논의한다. 기존의 문법이론 대신 한국어의 형태적 통사적 특성에 기인한, 성분들의 분할(partitions)에 의한 단위 (chunks) 분석방법을 제안한다. 근간은 동사구 장벽(VP-barrier) 알고리즘이며, 이 알고리즘은 한 문장안에서의 다양한 동사의 파생접사에 의해 형성되는 관형화, 명사화, 부사화 등의 파생구조와 내포된 동사구(인용문, 종속문 등)에 의해 형성되는 지역적 동사구내에서 그 성분들의 논리적인 분할을 구성하고 다시 그 다음 요소와 체계적으로 결합하는 관계로 확장하여 가능한 구조들을 생성한다. 다시 언어의존적인 발견적 규칙(heuristics)들을 점수화하여 가장 높은 점수의 단위구조를 적격한 구조로 선택한다. 이 방법은 하위범주화 및 의미정보를 사용하지 않는, 빠른 구문분석이 요구되는 시스템을 위해 고안되었으며, 집단적인 노력이 아닌 개인적인 노력 및 최소의 자원으로도 최대의 효과를 얻을 수 있다는데 그 의의가 있다.

With regarding to web GIS, OGC promotes WFS allowing a client to retrieve geospatial data encoded in GML which is a modeling language to encode the semantics, syntax and schema of geospatial information resources. Even though GML provides benefits for geographic description, it is too heavy to be processed by mobile devices. In order to address the issue, this paper evaluates GML service with WFS server and GML viewers. Through this paper, we get analyses of properties of GML geospatial data and the effects on wireless devices, which are expected to be fundamental materials onto a design of mobile applications.

In recent years, many organizations have been constructing their own large corpora to achieve corpus representativeness. However, there is no reliable guideline as to how large corpus resources should be compiled, especially for Korean corpora. In this study, we have contrived a new statistical model, ARIMA (Autoregressive Integrated Moving Average), for predicting the relationship between linguistic items (the number of types) and corpus size (the number of tokens), overcoming the major flaws of several previous researches on this issue. Finally, we shall illustrate that the ARIMA model presented is valid, accurate and very reliable. We are confident that this study can contribute to solving some inherent problems of corpus linguistics, such as corpus predictability, corpus representativeness and linguistic comprehensiveness.

Objectives: The purpose of this study was to assess predictors of health-related quality of life (HRQoL) in elderly Asian American and non-Hispanic White cancer survivors. Methods: We conducted cross-sectional secondary data analyses using the combined datasets from the Surveillance, Epidemiology, and End Results program and the Medicare Health Outcomes Survey. Results: Elderly Asian American cancer survivors reported a lower mental HRQoL but a comparable physical HRQoL relative to elderly non-Hispanic White cancer survivors. Stress factors, such as comorbidities, difficulties with activities of daily living, and a history of depressive symptoms, along with coping resources like self-rated health and the ability to take the survey in English, were significantly associated with mental and physical HRQoL. Among elderly Asian American cancer survivors, a significantly lower mental HRQoL was observed among those taking the survey in the Chinese language. Conclusions: The findings suggest that race exerts a differential impact on HRQoL. Interventions should be designed to address the distinct cultural, linguistic, and systemic needs of elderly Asian American cancer survivors. Such an approach could assist in reducing cancer-related health disparities.

Digital Manufacturing-based production could be very effective in shipbuilding in order to save costs and time, to increase safety for workers, and to prevent bottleneck processes in advance. Digital shipbuilding system, a simulation-based production tool, is being developed to achieve such aspects in Korea. To simulate material flow in a subassembly line at a shipyard, the product, process and resources was modeled for the subassembly process which consisted of several sub-processes such as tack welding, piece alignment, tack welding, and robot welding processes. The analysis and modeling were carried out by using the UML(Unified Modeling Language), an object-oriented modeling method as well as IDEF(Integration DEFinition), a functional modeling tool. Initially, the characteristics of the shop resources were analyzed using the shipyard data, and the layout of the subassembly line was designed with the resources. The production process modeling of the subassembly lines was performed using the discrete event simulation method. Using the constructed resource and process model, the productivity and efficiency of the line were investigated. The number of workers and the variations In the resource performance such as that of a new welding robot were examined to simulate the changes in productivity. The bottleneck process floated according to the performance of the new resources. The proposed model was viewed three-dimensionally in a digital environment so that interferences among objects and space allocations for the resources could be easily investigated

In this study, the applicability of a standard vector model was evaluated using RIMGIS vector data and a portal based river-geospatial information web service system was developed using XML and JSON based data linkage between the server and the client. The RIMGIS vector data including points, lines, and polygons were converted to the Geospatial Data Model(GDM) developed in this study and were validated by layers. After the conversion, it was identified that the attribute data of a shape file remained without loss. The GeoServer GDB(GeoDataBase) that manages a DB in the portal was developed as a management module. The XML-based Geography Markup Language(GML) standards of OGC was used for accessing to and managing vector layers and encoding spatial data. The separation of data content and expression in the GML allowed the different expressions of the same data, convenient data revision and update, and enhancing the expandability. In the future, it is necessary to improve the access, exchange, and storage of river-geospatial information through the user's customized services and Internet accessibility.

The ICELT(In-Service Certificate in English Language Teaching) is a highly practical course-based English teacher education program which integrates classroom teaching and off-site teacher training. This case study analyzes the three-year implementation of the ICELT program in Korea and discusses its effects and the implications for improving the inservice English teacher education system. It has been found that the course participants were satisfied with the quality of its execution, thinking that it contributed to their professional development in the areas of teaching practice, methodology and language competence. The study has identified several success factors as shared program goals among the course participants, including systematic selection of course participants, well-qualified tutors and the proper provision of resources including syllabus, teaching materials and course assessment system. Nonetheless, it has been suggested that attention needs to be paid to generalized application of the ICELT for English teacher education due to the limitations such as the heavy workload caused by the program, lack of course participants' collaboration with other teachers at their schools and tutors' poor understanding of the Korean education context. Bearing this in mind, the implications for improving the inservice English teacher education system in Korea have been discussed. Finally, further studies have been suggested, which are concerned with in-depth investigation in exploring the division of roles between native English speaking tutors and Korean ones and the impact of the program on the sustainability of course participants' professional development and the impact on schools.

The present study proposes a model for literature-based instruction within the context of a fashion design curriculum at a Korean university. The fashion design market continues to grow. The fashion design market now requires more cultural-bound strategies and efficient communication skills. The literature provides authentic resources and is highly relevant to the development of students' culture awareness as well as language awareness. Alice's Adventures in Wonderland written by Lewis Carroll contains various cultural contexts of the Victorian Era. The text provides explicit knowledge of the era depicted in both illustrations and satire languages. This study instructs students to analyze and interpret texts and illustrations so that they can engage critically and analytically in reading text to increase culture awareness and language awareness. The integration of literature and fashion design can provide students an opportunity to explore language choice and acquire refined knowledge of the target culture. Along with the text, illustrations in the literature provoke student's imaginative and creative thinking skills. Students can think and discuss many issues that deal with Victorian values and reinforce creative thinking skills. In the final stage, students can design fashion inspired by Victorian values and present their own designs using the acquired languages. This eventually leads students to adapt to a new notion for the fashion market and become competent communicators in the fashion world.

Due to the development of wireless devices such as smart-phone and internet, a lot of linguistic resources actively are opened in each area of expertise. Also, various systems using semantic web technologies are developing for determining whether such information are useful or not. In order to build these systems, the processes of data collection and natural language processing are necessary. But, there is few systems to use of integrating software and data required those processes. In this paper, we propose the system, uLAMP, integrating software and data related to natural language processing. In terms of economics, the cost can be reduced by preventing duplicated implementation and data collection. On the other hand, data and software usability are increasing in terms of management aspects. In addition, for the evaluation of uLAMP usability and effectiveness, user survey was conducted. Through this evaluation, the advantages of the currentness of data and the ease of use are found.
