비기능적 요구사항은 대상 시스템이 지원해야 할 기능적 요구사항의 속성 또는 품질 요구사항을 말하며, 소프트웨어의 품질 속성으로 반영된다. 이러한 비기능적 요구사항은 특히 성능과 관계된 부분의 설계를 결정하기 위한 중요한 기준으로 사용된다. 따라서 비기능적 요구사항은 소프트웨어 개발 생명주기 전반에 걸쳐 계속적으로 고려되고, 관리되어야 한다. 하지만 비기능적 요구사항의 모호성과 비가시적 특성으로 인해 도출 및 명세뿐만 아니라, 관리에도 어려움이 많다. 이에 본 논문에서는 NFR 그래프를 이용해 비기능적 요구사항에 가시성을 부여하고 비기능적 요구사항을 설계에 반영하여 비기능적 요구사항 관리의 효율성을 높이기 위한 비기능적 요구사항의 추적 기법을 제안한다. 비기능적 요구사항 개발 절차에 따라 지능형 조명 제어 시스템의 성능 요구사항 추적 방법을 사례연구로 수행하였으며, 이를 통해 종합적으로 비기능적 요구사항 관리의 효율을 높이고자 한다.

This paper investigates the relative effect of each ISO 9001 : 2000 quality management system's requirement and business performance. The empirical tests are conducted in ISO 9001 certification companies. As a result, the $1^{st}$, it shows the requirements positively affect performance of financial. The $2^{nd}$, also it shows the requirements positively affect non-financial performance. The $3^{rd}$ also it show the non-financial performance positively effect performance of financial performance.

Purpose - The buyer's right to withhold performance is a useful and important self-help remedy to protect himself from the seller's breach of contract, and it is also the coercive means to induce the seller to perform his part of contract. However, the buyer's exercise of such a right often exposes himself to the risk of breaching the contract. This is generally due to his ignorance when he is entitled to the right and also uncertainties inherent in the law. Therefore, the purpose of this paper is to examine what the requirements should be fulfilled before the buyer exercises the right for the seller's actual breach of contract. Design/methodology - In order to achieve the purposes of the study, it executes a comparative study of the rules as to the requirements for the buyer's right to withhold performance for the seller's actual non-performance under the CISG and the CESL. It mainly focuses on performance due, the seller's non-performance, the buyer's readiness to perform and the requirement of notice. Findings - The main findings of this comparative study can be summarized as follows: Although the CISG has no expressive provision for the buyer's general right to withhold performance for the seller's actual non-performance, it may be inferred from the general principles the CISG underlies, synallagmatic nature of the contract. In addition, it can be drawn by analogy from relevant provisions of the CISG. On the other hand, the CESL expressively provides that the buyer has a general right to withhold performance where the seller fails to tender performance or perform the contract. Therefore, it seems that the position of CESL is rather easier and more apparent to allow the buyer to withhold performance for the seller's non-performance. Originality/value - Most of the existing studies on the right to withhold performance under the CISG have centered on the right to withhold performance for an anticipatory breach of contract. On the other hand, there have been few prior studies on the right to withhold performance for the actual nonperformance during a contractual period of performance. Therefore, this paper examined the requirements for the buyer's right to withhold performance under the CISG and the CESL in a comparative way for the seller's actual breach of obligation. In this conclusion, it may provide practical and legal considerations and implications for business people who are not certain about the right to withhold performance.

Data from 24 feeding trials conducted on lactating cattle from different institutes across India were subjected to regression analysis to derive requirements of ME, TDN, CP and DCP for maintenance, milk production and body weight gain. Maintenance requirements for ME, TDN, CP and DCP were 598 KJ, 39.5 g, 6.27 g and 2.90 g/kg $W^{0.75}$, respectively and the corresponding requirements for production of 1 kg 4% FCM were 5,023 KJ, 332 g, 82 g and 58 g. The corresponding requirements for one g gain in BW were 27 KJ, 1.78 g, 0.44 g and 0.19 g. Regression equations had high $R^{2}$ values (0.67 to 0.90) and the equations (Fvalue) as well as coefficients were highly significant (p<0.001). Regressed values were used to develop feeding standards. Derived values matched well with the actual intake versus performance of animals under diverse feeding conditions. The new standards so derived predicted requirements and intake of nutrients for different production levels better than existing feeding standards; as these are based on a more thorough analysis of a larger database, the new feeding standards will be appropriate for wide use in India.

우리나라 민간 소형 비행기 동력장치의 감항기준은 KAS Part 23(소형 비행기)과 Part 33(엔진)에서 규정하고 있다. 이 기준은 미연방항공청(FAA)의 FAR Part 23 및 Part 33과 유럽항공안전청(EASA)의 CS-23 및 CS-E와 동등한 체계를 갖는다. FAA와 EASA는 소형 비행기의 감항기준을 전면 개정하였다. 설계 방식과 적합성 입증방법을 지정한 규범적 규정에서 안전한 성능을 달성하도록 목표를 지정하는 성능기반형 규정으로 전환한 것이다. 이러한 개념적 전환에 따라 동력장치 감항기준 또한 기존의 요건에서 대폭 변경되었다. 이에 따라 FAA의 동력장치 인증요건 개정 사항을 살펴보고 우리나라의 감항기준 개정 방향을 고찰하였다.

국내에서 공연 예술의 아카이빙 방안에 관련된 연구들은 최근 다방면으로 이루어져 왔으나 클래식 음악 공연정보를 한 곳에서 체계적으로 확인하고 지난 공연정보를 얻을 수 있는 디지털 아카이브의 구축은 시도된 바도 없었고 이에 대한 연구도 이루어진 일이 없었다. 이 연구에서는 모든 클래식 음악 공연에 대한 정보를 제공하고 보존하며 서비스할 수 있는 참여형 아카이브 포털을 제안하고, 선행연구에서 확인된 공연 아카이브 포털의 요건 및 요구사항을 바탕으로 기능을 설계하고자 하였다. 이를 위해 아카이브 포털의 기능요건을 확인하고 클래식 음악 공연정보의 특성에 맞추어 재구성하였으며, 메타데이터 요소를 설계하였다. 또한, 검색 및 패싯 내비게이션과 이용자 참여 및 커뮤니케이션 기능의 설계와 구현 방향을 제시하였다. 마지막으로 이 기능들의 인터페이스를 구현한 프로토타입을 개발하였다.

In general, an Architecture of a system is embodied as applied results of a requirement analysis of a system in early development phase. These efforts play a important role in analyzing and understanding a system considering operational, functional, and physical view and deriving a correct solution before developing the system. In this paper, the architecture of the Tube Transportation System(TTS) known as the new transportation system in Railway Domain is depicted by performance parameter has already developed. The existing performance parameters are shown by a variety of types with many meanings rather than types of general requirements refined. As these early performance parameters have analyzed and complemented to a level of requirement by requirement managers and other domain specialists, the architecture of the Tube Transportation System was developed systematically and then system requirements will be drawn up definitely. The presented architecture will provide a framework of developing a TTS and also offer an information in performance analysis of TTS.

This paper describes the RF performance issues of UE RF Transceiver for W-CDMA system based on 3GPP specifications. the parameters of transmitter and receiver are derived from the viewpoint of RF performance. In order for UE to achieve high performance, the transceiver performance requirements such as ACIR, EVM, Peak Code Domain Error, spectrum emission mask, frequency error stability and TX power control dynamic range for transmitter and reference sensitivity level, blocking characteristics, noise figure, ACS, linearity, AGC dynamic range for receiver are considered. On the basis of the required parameters, the UE RF transceiver is designed and then implemented. The evaluation of RF performance is accomplished through practical test scenarios.

The performance and reliability of foreign servomotors and domestic servomotors for manufacturing robots were compared and verified. The mass productivity was confirmed by satisfying the requirements of the demanding companies. The servomotor was designed in consideration of mass productivity while satisfying the requirements of the demanding company. It was mounted on a real robot to check its performance and reliability. To secure mass-production performance, we designed and manufactured easy-to-manufacture parts and jigs to manufacture servomotors and achieved the goal of the mass-production evaluation of servomotors through individual performance evaluation, robot mounting test evaluation, and supplementation.

There are many specific requirements in the actuation, system for high speed underwater vehicle, such as size, weights, power etc.. In this paper, a high performance compact hydraulic actuation system to satisfy such requirements was designed. The controller of the system was designed using both the conventional PID and VSC which were known to have reliability, robustness respectively. The performance analysis was done for the designed actuation system through computer simulation.
