In both inside and outside of our country, the interest of the new generation S/W architecture, the SOA(Service Oriented Architecture) is whooped up. We expect that the SOA will become general S/W architecture in several years, but the most compaines of S/W Industry still think that the SOA have much risk to adapt as their s/w architecture. In this paper, We performed the senario based verification of the SOA quantitatively and qualitatively, and presented the validity of the S/W architecture view and the method of adoption of the SOA.

S/W product line is a S/W product or a set of S/W system, which has common functions. We can develop a specific S/W product, which satisfiesrequirements of a particular market segment and a mission in a specific domain by reusing the core asset such as the developed S/W architecture through the S/W product line. S/W development methodology based on the S/W product line can develop a S/W more easily and fast by reusing the developed S/W core asset. An advanced country of S/W technology selects S/W product line as a core field of S/W production technology, and support technology development. In case of USA, CMU/SEI (Carnegie Mellon University / Software Engineering Institute) developed product-line framework 4.0 together with the industry and the Ministry of National Defense. Europe is supporting the development of product line technology through ITEA(IT for European Advancement) program. In this paper, we aim to construct reference architecture of S/W product line for production of the S/W product line.

국내외적으로 차세대 아키텍처인 SOA에 대한 관심이 높아지고 있으며, 수년 내에 SOA가 일반적인 아키텍처가 될 것으로 전망 되고 있다. 하지만, 여전히 많은 기업들이 막연하게 SOA가 현실화 되기 에는 아직은 많은 위험 요소가 있는 것으로 판단 하고 있다. 본 논문에서는 SOA기반 차세대 Architecture에 대한 시나리오 기반의 정성적, 정량적인 검증을 수행 하여 아키텍처적인 관점에서 타당성을 제시하고, SOA를 실제 구축 프로젝트에 적용하기 위한 방안을 제시하여, 이론 및 사상적인 측면에서 벗어나 현실화된 Architecture로써 SOA가 도입 될 수 있도록 하고자 한다.

S/W 제품계열(S/W Product Line)은 공통의 유사한 기능을 지닌 S/W 제품 또는 S/W 시스템의 집합을 의미한다. S/W 제품 계열을 통해 특정 영역의 시장과 용도의 요구사항을 만족하여 특정 S/W 제품 개발시 미리 구축된 S/W 아키텍처 등의 S/W 핵심 자산을 재사용하여 개발한다. S/W 제품계열 기반의 S/W 개발방식은 미리 구축된 S/W 핵심자산을 재사용함으로 처음부터 전체 시스템을 개발하는 방식보다 쉽고, 빠르게 S/W를 생산할 수 있다. S/W 기술 선진국들은 S/W 제품계열을 S/W 생산기술의 핵심 분야로 선장하고 중점적으로 기술 개발을 지원하고 있다. 미국의 CMU/SEI는 산업체 및 국방성과 함께 제품계열 프레임워크 4.0 (Product-Line Framework 4.0)을 개발하였고 유럽은 ITEA(IT for European Advancement) 프로그램에서 제품계열 기술 개발을 지원하고 있다. 그러나 국내의 경우 S/W 개발의 생산성 향상 방안으로 제품계열 기반 S/W 생산기술의 필요성을 인식하고 있으나, 기술 개발 투자는 미흡한 상황이다. 본 논문에서는 이러한 S/W 제품계열 생산을 위한 S/W 제품계열의 공통 아키텍처를 정립하는 것을 목표로 하고 있다.

An underwater robot S/W framework consists of various sub-modules such as sensory data processing module, thruster control module, cognition module and behavior control module. Performance of a robot is determined by not only the efficiency of algorithms used but also effectiveness of their implementations. One most important factor of the effective implementation is the efficiency of data sharing module, as it transmits signals and data between the sub-modules and thus is directly related to the cycles of sensing and control The ideal data sharing module enables immediate access to any data source irrespective of system configurations. In reality, however, there are lots of obstacles including limitation of processing capacity of source modules, delay over network, and scheduling latency of operating systems. The paper proposes a new data sharing architecture and programming models to effectively handle such obstacles in implementation of underwater S/W framework on a small scale distributed computing system.

This study conducts a questionnaire with undergraduate students in the Dept. of Architecture who will lead the architectural field in future, examines environment and perception of CAD in their home and universities and aims at supplying the data required for setting CAD educational index and building its use environment, and it could obtain the following results. Individual CAD environment of undergraduate students in the Dept. of Architecture reach a considerable level in hardware part, but they don't have the same level in software part as the hardware and use illegal copy programs. It is shown that they spend their time in using CAD for five to eight hours a week and its main purposes are to perform a project related to architectural design or make report requiring drawing. Major places using CAD are CAD room in university or public PC room equipped with CAD compared to their own houses and most of them have a negative recognition of the convenience of its use. Their satisfaction with CAD use is considerably high and when they submitted their assignments of architectural design project by means of CAD, they had a positive evaluation from their professors and they have such hopes that 'Korean Support Strengthening', 'lowering price through version supply for students' and 'diversification of design symbol' in CAD S/W, and especially, most of respondents have an intention to purchase the original goods when version only for students will be marketed in future. Accordingly, for a qualitative improvement of CAD environment for undergraduate students in the Dept. of Architecture, universities must be equipped with the various types of CAD S/W and Applications and students' opportunity to access them should be increased. In addition, a method which can enhance using convenience of CAD room and PC room is required and CAD related S/W developers must market the version for students which consider the reality of undergraduates in Korea properly with an appropriate price level in order to settle a sound S/W culture.

Generally, although securing the condition and location of container freights or normal freights, which load a fresh goods, has been a very important issue in the cold-chain system implementations, it has not gotten out of the traditional methods in the related business world yet. To solve this problem, we propose the designing method and architecture which can be used to implement a smart cold-chain monitoring automation systems. The proposed system architecture is based on the oneM2M standards, and it has 3 layers and entities, which can be implemented to S/W and H/W, network services layer and entity, common services layer and entity, application layer and entity. Based on this architecture, we will not only expect an innovative retrenchment of distribution cost, but also automatically secure the freight condition and location.
