This paper propose an expanded ASP exclusive development framework method. We applied a module to the suggested method which suit to develope ASP. Proposed method is a kind of module, which manages MVC develope methodology and treats Query and ASP information as a XML. It has flexibility which meets the client's request quickly. Using inherited base model which previously exist in template source, developer only concerned with development methodology so that they can reduce development time and reinforce a integrity of system. We proposed these improvements as a framework. Experimental results validate our scheme, showing a fewer number of files and a better flexibility than other development method, and also about 29% of program code has been reduced.

SCA (Software Communication Architecture), which has been adopted as a SDR(Software Defined Radio) Forum standard, provides a framework that successfully exploits common design patterns of embedded systems software. However, the SCA is inadequate as a component framework since it does not explicitly specify (1) a component model that defines how to express a component interface and how to implement it, (2) a package model that defines what and how to package in deployment units, and (3) a deployment model that defines the deployment environment and deployment process. In this paper, we propose a SCA-based component framework for SDR. Specifically, we present (1) a component model that defines a component as a specialized CORBA object that implements object management functionality, (2) a package model exploiting the existing XML descriptors of the SCA, and (3) a deployment model that defines a SCA-based deployment environment, a boot-up process that restores the deployment state, and a deployment process that supports lazy application instantiation and dynamic component replacement.

The web services concept is rising as a standard to integrate heterogeneous systems in distributed environment based on XML messaging. Recently, for that reason, many companies are trying to use web services for their B2C and B2B business. In order to successfully introduce the web services, it is required to guarantee a differentiated quality of web services. However, most of the current web services cannot provide differentiated policies for requested messages and the existing web servers cannot consider appropriately the quality factors of web services in the service level agreement between provider and consumer. In this paper, we analyzed appropriate quality factors of web services in application level and suggested priority allocation strategy for processes dealing with messages of web services using those factors. This strategy can allocate dynamically a priority to satisfy the service level agreement.

The area of business applications in the internet are extended enormously in result of fast development of computing and communication technologies, increase of internet use, and use of intranet/extranet in enterprise information system. Widely spread the use of the internet, there are various applications for Business to Business (B to B) or Business to Customer(B to C) model that are based on the intranet or extranet. This paper designed and implemented the Web-based Electronic Bidding System for Business to Business (B to B) model. The technical issues of electronic bidding system in the internet are involved in the connection between web client and server, electronic data interchange for the contract document, and security solution during the bidding and contracting processes. The web-based electronic bidding system in this paper is implemented using Java applet and servlet as a connection interface for web client and sewer, XML/EDI-based documents for a bid and a contract, and bidding server and notary server for enhancing the security using PKI(Public Key Infrastructure)-based public key cryptography, digital signature and Certification Authority (CA).

In this paper, we present an automated API translator for embedded software development based on a model-driven approach. Since MDA(Model Driven Architecture) provides little support for the development of embedded software, we propose a new method which contains the MDA's advantage, automation of implement process, and can solve the problem of real-time overhead. First, we define 'generic APIs' which do not depend on any RTOS's but provide most of typical RTOS services. We can describe RTOS-related behaviors of target application using these generic APIs in a CIC(Common Intermediate Code). Then, we propose a transformation tool for translating a CIC using generic APIs into a C-code for specific RTOS. The proposed API translator converts them into C-code using XML transformation rule which is defined outside. It indicates that an API translator extends to other RTOS's by modifying or adding the transformation rule. From the experiment, we validate the proposed method.

There are many different ID representation forms depending on the media or applications. In case of RFID tag, ID representation form must be followed by the rule of ISO/IEC 15962. In this study, we developed the efficient ID conversion algorithm between ID representation form on RFID tag and Internet. The main idea is on the use of XML based ID profiles and three step logical IDs forms. The algorithm was tested by the typical three kinds of real IDs such as EPC, ISO/IEC 15459 KKR Code, and mCode which are the typical meta-IDs can be defined in ISO/IEC 18000-6C tag.

Advanced wireless network and sensor technologies are capable of collecting information such as temperature, humidity, weight, and location about objects at real time in logistics area. Besides, users want to be notified of contextual information about interest of objects whenever they want it and wherever they want it. To satisfy these requirements, applications should collect and analyze contextual information at real time, and must support a service that can notify it to wanted users. Event-based service is one of the way to satisfy these requirement of users. In this paper, we design an event notification system focused on location- and RFID-based logistics area. To do this, we present XML-based event expression model, ECA-based profile definition model, and an algorithm that has high scalability by distinguishing event filtering in two steps. Based on these designs, our implemented system can apply to not only logistics area but also intelligent traffic control system based on RFID or GPS devices.

Continual attempts to accumulate and apply information eventually gave birth to the concept of the "Semantic Web". Thus, the "Semantic Web" can be defined as a product of mankind's desire to standardize information. At the same time, the term provides "a method that standardizes mankind's concept of linguistical expression", and can be noted as an effort to combine such methods into a standard web environment that may materialize to form a catalogue. This study introduced RDF schema, ontology languages for the semantic web, and ontology-based systems. The purpose of the study was to construct a system based on the semantic web environment's ontology by utilizing the ontology schema derived from the facettype Art and Architecture Thesaurus(AAT). The aforementioned ontology schema is based on the Web Ontology Language(OWL), which is being widely considered the standard ontology language for the W3C-centered semantic web environment.

Privacy protection can only be achieved by enforcing privacy policies within an enterprise's on and offline data processing systems. There are P-RBAC model and purpose based model and obligations model among privacy policy models. But only these models each can not dynamically deal with the rapidly changing business environment. Even though users are in the same role, on occasion, secure system has to opt for a figure among them who is smart, capable and supremely confident and to give him/her a special mission during a given period and to strengthen privacy protection by permitting to present fluently access control conditions. For this, we propose Integrated Privacy Protection Model based on RBAC. Our model includes purpose model and P-RBAC and obligation model. And lastly, we define high level policy language model based XML to be independent of platforms and applications.

공간정보의 효율적 공유를 위해 인터넷 기반 GIS소프트웨어 개발 및 응용과 관련된 연구가 활발히 진행 중에 있다. 여러 인터넷 GIS의 기본적인 요구사항 및 현재까지 개발모델과 문제점을 살펴보고, 표준 인터넷 기술을 기반으로 최근 웹 기술 표준 동향을 포함한, OpenGIS상호 운용성이 지원되는 인터넷 GIS기본 구조를 제시하고자 한다. 표준화될 인터넷 GIS 속도 향상과 TCP/IP상의 보안문제가 해결되어야 하고, OpenGIS에서 구성하고 있는 공간 데이터 공유를 위한 표준 사양을 준수할 뿐 아니라 클라이언트/서버의 부하가 최적화된 구조여야한다. 특히 웹 중심의 각종 인터넷 기술들, 즉 HTTP NG. XML, SSL등의 표준 기술이 함께 적용되어야 한다. 새로운 인프라구조는 GIS D/B에 포함된 확장된 (Enhanced) HTTP/MAP 서버와 클라이언트로 구성된다. MAP클라이언트는 MIME-TYPE 에 따라 GIS데이터를 표시할 수 있는 윈도우 환경으로 변환되며 GIS 데이터셋은 XML을 기반으로 하는 MapML(Mapping Makup Language)를 통해 형식을 정한다. 클라이언트가 MapML 토큐먼트를 통해 정의된 구획의 레이어와 벡터 데이터를 요청하고, Map서버는GIS D/B에서 WKB 혹은 소위 VML 형태로 추출하여 클라이언트로 보내주게 된다. 주어진 구획은 MapML로 정의된 속성들을 통해 각종 부가 정보를 열람할 수 있다. MAP은 HTTP와 같은 형태로 동작하므로 전자인증, 암호화를 통한 GIS정보 보안, 클라이언트와 서버 부하의 효율적인 분배 XML을 통한 다양한 GIS속성표현이 가능하다. 본 구조는 Apache +Amiya + Crass D/B+ MapML 환경에서 구현되고 있다.팔일 전송 기법을 각각 제시하고 실험을 통해 이들의 특성을 비교분석하였다.미에서 uronic acid 함량이 두 배 이상으로 나타났다. 흑미의 uronic acid 함량이 가장 많이 용출된 분획은 sodium hydroxide 부분으로서 hemicellulose구조가 polyuronic acid의 형태인 것으로 사료된다. 추출획분의 구성단당은 여러 곡물연구의 보고와 유사하게 glucose, arabinose, xylose 함량이 대체로 높게 나타났다. 점미가 수가용성분에서 goucose대비 용출함량이 고르게 나타나는 경향을 보였고 흑미는 알칼리가용분에서 glucose가 상당량(0.68%) 포함되고 있음을 보여주었고 arabinose(0.68%), xylose(0.05%)도 다른 종류에 비해서 다량 함유한 것으로 나타났다. 흑미는 총식이섬유 함량이 높고 pectic substances, hemicellulose, uronic acid 함량이 높아서 콜레스테롤 저하 등의 효과가 기대되며 고섬유식품으로서 조리 특성 연구가 필요한 것으로 사료된다.리하였다. 얻어진 소견(所見)은 다음과 같았다. 1. 모년령(母年齡), 임신회수(姙娠回數), 임신기간(姙娠其間), 출산시체중등(出産時體重等)의 제요인(諸要因)은 주산기사망(周産基死亡)에 대(對)하여 통계적(統計的)으로 유의(有意)한 영향을 미치고 있어 $25{\sim}29$세(歲)의 연령군에서, 2번째 임신과 2번째의 출산에서 그리고 만삭의 임신 기간에, 출산시체중(出産時體重) $3.50{\sim}3.99kg$사이의 아이에서 그 주산기사망률(周産基死亡率)이 각각 가장 낮았다. 2. 사산(死産)과 초생아사망(初生兒死亡)을 구분(區分)하여 고려해 볼때 사산(死産)은 모성(母
