In the next near future, the human would like to use the small unmanned ground vehicle(SUGV) on the diverse fields. Specially the world of today is tried to apply with operating the task on very difficult working environments such as some dangerous or unreachable area. To work this task, this vehicle should be guaranteed with the high level of reliability, safety, and performance. In this paper, we propose to focus on not only the functional requirements, but also the non-functional requirements based on software architecture at the design stage for developing the embedded system. Through focusing on the non-functional requirements on this software architecture, we can obtain the design goal of the target system and also show the enhancement of reliability, safety and performance with 'Vtune' performance analysis tool.

The study investigated the users' functional requirement, degree of acceptance and preference of game broadcast real-time review .Secondly it comparatively analyzed the types and locations of game broadcast real-time review through eye tracking tech. The results show that users have high functional requirements and high acceptance for game broadcast real-time review but their preference has no significant correlation with the feature. Among the types of game broadcast real-time review the type with translucent text bubble took the highest visual attention. The above shows that the users' visual behavior has the tendency of special style. The visual attention analysis results of different types and locations of game broadcast real-time review in the study can play a guiding role in the interface design of real-time review feature in the future.

With development of global network in the 21th century, Korea has recklessly accepted western culture occurred damages to our identity. Development of traditions in a modern way contribute us Korea identity and future vision. This study has studied about combination traditional material and contemporary material with a view to diversified user's desires and individuality. This object shows that function and decoration coexist together, and design reflects mans life and thinking of the age as a reflection of sociocultural phenomena. The purpose of this work to create the object that meets mans requirement and even foresees the possibility of such requirement through converting into various appearances. Different concepts including closed singleness and expansion within open structure coexist one element. also this objects suggest that transformative expressions that simplify or transform, the forms can be freely changed by consumer's emotional changes. Here, light and form are experimented for creating diversified emotions. Considering design as positively responding behavior against the limitations given by environment instead of the solution to simple functional requirement, future design will find Its value more In more active response.

It is often claimed that the descriptive way of documentation is insufficient to define software requirements as being unambiguous. This is caused by not only the difference of knowledge and understanding of the stakeholder as to system but also the difference in the way of documentation like method of representation as well as depth of description. The study explains the process and results of applying a diagraming tool like UML to improve the requirements of GLORY(GLObal Resource management sYstem) initially defined in descriptive way. Especially, the result shows that the requirements are more accurately improved with the good hierarchies and well-leveled functionalities, with the help of diagraming tool, expecting easy maintenance of requirements and prevention of omission of requirements.

All information system is information security system that enforced security function. To improve qualify of information security system, suity requirement analysis and specification must be Performed by consistently and typically at early requirement analysis step. In this paper, we propose a security requirements analysis and specification model and process by using Misuse Case Model that extends UML's Use Case Model. And, we propose a cost-effective security product selection algorithm that security product is sufficient of all constructed security functional requirements. It may raise quality of information security system that developed through proposed model and process.

Less efforts has been made in developing specifications and verification techniques for quality requirements. This paper suggests specification and traceability methods supporting quality issues such as usability, performance, and understandability when developing information systems with UML notation. With traceability checking methods that augment quality extension to the use cases and sequence diagrams, developers can confirm the level of implementation for both functional and nonfunctional requirements beforehand.

In this study, unattended Light Rail Transit System (K-AGT) is a general-purpose standards safety requirements of IEC 62267 based System Engineering Process (SEP) was used. Functional analysis and physical architecting for each requirements through the vehicle was classified into sub-systems, design was analyzed in terms of SE. The analysis of the proposed system engineering process, unattended train operation (UTO), driverless train operation(DTO) design of the safety measures to be used as the basis is studied.

There is a world-wide trend to implement autonomous TM/TC system in satellite operations. KARI developed CALS(Command AutoLoader System) for KOMPSAT-1 operation automation in 2004. This paper provides system requirement, system design, system test and operational procedure. Through test with simulator and KOMPSAT-1, CALS was verified to meet all functional and operational requirement like scheduling, real-time telemetry check, CRC generation, command grouping. CALS is expected to be used in KOMPSAT-1 normal mission operation in end of 2004

CD-ROM drive is improved in rotation speed up to 10,000 rpm. But Vibration and Noise are also increased simultaneously more and more. So many attempts are tried to reduce the unexpected effects. Most attempts are not enough to cover the increasement of Noise and Vibration. Merely availed tries are accumulated in many part and it makes the structure complicated. The Axiomatic approach could arrange the order of design and estimate the optimum design in good oder. In Axiomatic Approach, the composition is divided by Customer Requirement, Functional Requirement, Design Parameter and Design Matrix in large portion. This method also could show more effective way to design before making a prototype.

This study is on the behavior analysis which can define and verify a system requirement through a behavior diagram for High speed rail system. The model considered in this study is limited to the preconditioning control of the control system specification for HSRS. To build an executable model, requirements should be decomposed first into leaf node requirements. The behavior model is composed of input, output, and functions which are linked with leaf node requirements. It is important that a single requirement must specify a single Auction. Using the developed executable model and the traceability between requirements and functions, this study found out a lot of static and dynamic inconsistency, missed and derived requirements. This is to develop and executable behavior model to do functional analysis and be able to verify the integrity of a specification.
