In this paper we describe SLA metrics and software architecture for newly upcoming IP TV service. Firstly we show the general description for IP TV. This consists of brief description of IP TV, the general figure of configuration and elements of IP TV network and communication protocol stack of IP TV data transmission for deriving communication quality parameter. And we propose SLA metrics depending on quality measurement point. According to the measurement point the measurable SLA metrics are different. The total view of the IP TV SLA measurement and management architecture is shown. When the quality measurement point is the routers that consist of internet node, the IP media NMS is the quality collection system. And when the quality measurement point is the IP TV STB(Set-Top Box), the IP media collector and Quality Collection Server are the quality collection system. And we show the software block diagram of IP TV SLA processing system and the other related network management systems.

The reuse by using framework is proposed to improve productivity. It is a set of usable and expandable classes and their connectivity. But frameworks are described with programming languages, it is hard for developers to learn the collaborative patterns of a framework by reading it. Patterns are one approach to improving the documentation. But this should be redesigned to expand and redefine the framework. The necessity of the formal description of architecture information is being proposed to relate to programming language. This paper support the following points. First of all, it has been proposed the description of the needed elements when developing a framework using ADL. Secondly, the current development process has been refined to be suitable for developing the domain framework. Thirdly, it has been proposed the development of a application using a framework implemented by an architecture information described with ADL. Overalls, the main contents of this research is defining the ideas of a description and development of an architecture framework using ADL.

The US DoD architecture framework defines architecture Products according to three viewpoints : operational view, system view, and technical view. But, its coarse-grained development process causes leakage of the details In transforming among different views. It also uses different methods for architecture products development, so that the levels of those products are not consistent. So. we propose MND AF(Ministry of National Defense Architecture Framework) for military environment to solve those problems. We propose additional architecture products to achieve consistency, including “architecture disciplines definition description,”“organization-to-activity relationships matrix,” “system definition description,” and “technical reference model,” etc. We also propose the architecture development process in more detail through seven steps. In addition, we propose the applicability of those products to the life cycle processes of the acquisition management. MND AF can provide consistency and traceability of architecture products, provide the basis for sl·stem integration and interoperability. Also, architecture developers can construct architecture in a more effective and efficient way through MND AF.

Purpose: The planning and design of hospital generally requires the participation and consultation of skilled experts since it has more complex space program than any other buildings. Therefore, the BIM systems for the planning of hospital have been tried continuously. The purpose of this study is to identify the precondition for space Program validation of healthcare architecture based on BIM, which is recently receiving wide attention. Method: For this study, United States, Australia and Finland's guidelines were analyzed among the description space program validation system in 14 overseas BIM Guidelines. And the propose precondition that can be applied to healthcare architecture from among these description of space program validation items, target, process etc for General building. Result: 1) spatial program validation is the following four evaluation phase. Step 1: Standard setting phase Step 2: BIM model accuracy assessment phase Step 3: space validation phase Step 4: Performance evaluation phase 2) The standards for the building elements at Standards Setting stage is considered to the standards for the architectural elements of General building. 3) Healthcare Architecture Area calculation method is considered to be reasonable that borrowing the area calculation standard of general architecture according to the UIA of international standards. However, Be proposed of measuring method that reflect the efficiency of the design process step-by-step area calculation method. The performance assessment indicators of reflect the Hospital uniqueness have to developed. And the research needs to be carried out continuously according to the purpose for healthcare architecture of feature-oriented. Implications: In this paper like to understanding that precondition of space program validation considering the BIM. As a result, understanding to condition about step of the evaluation, the evaluation standards. Is expected to keep the focus on the development of performance indicators that reflect the uniqueness of the hospital for the efficient evaluation of the Hospital building.

아키텍처에 대한 기술은 아키텍처 평가와 검증을 위해서 반드시 필요하다. 아키텍처 기술(Architecture Description)을 위해서 아키텍처 기술언어, 아키텍처 모델에 대한 다양한 연구들이 있었다. IEEE-1471의 아키텍처 기술을 위한 개념적 모델이 아키텍처 기술에 대한 일반적인 모델로 제시되었고 이후에 아키텍처 기술에 대한 새로운 요소들이 제시되었다. 그러므로 IEEE-1471의 개념적 모델은 새로운 요소들의 개념 사이에 혼란이 존재한다. 본 논문에서는 IEEE-1471의 개념적 모델을 바탕으로 이후에 제시된 세 가지 요소를 추가함으로써 IEEE-1471의 개념적 모델을 확장하고자 한다.

소프트웨어를 아키텍쳐 수준에서 정확하고 엄밀하게 설계, 분석하는 것이 점차 중요해짐에 따라 사용이 쉬우면서 기술적으로 성숙된 아키텍쳐 기술언어(ADL Architecture Description Language)의 필요성이 커지고 있다. 본 논문에서는 컴포넌트 기반의 도메인 아키텍쳐 모델링 시 C2 스타일의 아키텍쳐 기술을 지원하는 ADL을 정의한다. 본 논문에서 정의한 ADL은 자바(Java)와 유사한 구문으로 컴포넌트 명세와 아키텍쳐 명세를 분리하여 기술할 수 있는 표기 형식을 제공한다.

This paper deals with the effects of fluorescent lamp description and luminance level on the occupant's brightness perception and other sensation in building interiors. The following experiments were conducted: the subjects compared on room lit by daylight fluorescent lamps with the other room lit by the different lamp description at equal luminance at equal luminance level. The degree of that effect decreased with a rise in luminace level. The brightness perception had high correlation with the visual clarity and no correlation with favorite sensation.

In this paper, we propose a unified systolic array for the computation of the 2D discrete cosine transform/discrete sine transform/discrete hartley transform (DCT/DST/DHT). The unified systeolic array for the 2D DCT/DST/DHT is a generalization of the unified systolic array for the 1D DCT/DST/DHT. In order to calculate the 2D transform, we compute 1D transforms along the row, transpose them, and obtain 1D transforms along the column. When we compare the proposed systolic array with the conventional method, our architecture exhibits a lot of advantages in terms of latency, throughput, and the number of PE's. The simulation results using very high speed integrated circuit hardware description language (VHDL), international standard language for hardware description, show the functional validity of the proposed architecture.
