Urban transit consists of signaling system, railway systems, power facilities systems and the other complicated facilities and the standards notify the standardizations, safety standards, performance standards and quality certification standards according to the Urban Transit Act. The government notifies and recommends these standards to improve the performance, safety and maintenance efficiency of urban transit. Now, we need to manage the records and traceability of the standards because they have reciprocal relations with the others so that, if some standards have been changed it could make some problems to the others. As a result, in this research, we suggest the way to manage the traceability of the standards by using the computation support tools.

The rural area has aged and depressed for urban area in Korea. Furthermore, the rural house has deteriorated and is vulnerable to disaster which collapse, fire, landslide, and so on. For this matter, it need to an evaluated system for deteriorated level of rural house. The evaluated system has a repairing method and an estimated cost for rural house to offer native in rural area. This study could draw evaluation factor for deteriorated level of rural house as a basic study for the evaluated system. The evaluation factors is compared the Korean housing performance grade indication system, the Korean green building certification criteria, and the Japanese housing performance indication system. As a result, they could eight types. There are a mothproof, an waterproof, a finishing material, an asbestos cement slate of roofing, a mobility right, an opening and closing of doors and windows, an indoor environment.

The buildings constructed with steel structure is coated with certified fire resistive material to resist from fire. Coating materials lose their initial performances as time passes, so they need some maintenance. Fireproof spray-application also loses its performance and this performance loss of thr fireproof spray-application is very important because fire resistance of buildings depends on fireproof spray-application. So this study is to develop Acceleration durability test method of Fireproof spray-application, and use the Certification of fire resistant coating system.

In this paper for developing and implementing the car driver's front lane attention enhancement developed system using the car camera. The developed system automatically alarm the car driver when front cars make the dangerous situation. We use Raspberry Pi camera module V2 as car camera module, Raspberry Pi 3 board as hardware main board of implementing embedded system and develop the application library module which can be operated on the Raspberry situation. The application library module widely consist of two part, front car recognition part and dangerous situation distinguish part. Our developed system satisfy the performance test of the target system at the software test certification laboratory of TTA(Telecommunication Technology Association). We test four items as attentive car recognition ability at day and night, system performance, response time. We get the performance of developed system based on the four goal. The car driver's front lane attention enhancement system in this paper will be widely used at the ADAS(Advanced Driving Assistance System) because of the better performance and function.

비행시험은 개발 항공기의 다양한 성능검증을 포함하여 감항기술기준에 대한 안전성을 입증하는 최종시험으로서 중요성이 크다. 특히, 민간 항공기의 비행시험은 개발업체의 경험 및 노하우에 의해 기술 보호성격이 강하며, 다양한 시험항목과 비행조건에 의해 비용이나 시간측면에서 효율적인 비행시험 수행 및 비행시험 기법의 확보는 필수적이다. 본 논문에서는 이륙 및 착륙성능 입증을 위한 이착륙 비행시험에 대해 지상관측법과 DGPS를 활용한 비행시험 기법을 제안하고 실제 비행시험을 수행하여 그 결과를 비교하였다.

In this paper, a fundamental study for developing and introducing a new assessment method of the 'Energy Performance' in G-SEED that uses dynamic building energy simulations was conducted by comparing and analyzing the corresponding issues of domestic and foreign green building certification systems. The most significant part of the new assessment method to be developed was a development of a modeling guideline for a reference building using dynamic building energy simulations. In this paper, the composition and detailed contents of the guideline was created to comply with domestic energy codes. In addition, one of the most influential part of the result in the simulations, the 24-hour building operation schedule for a reference building, was created considering the equity with the ECO2 program that is the evaluation tool of one of the current assessment methods in the "Energy Performance". In order to improve the completeness of this guideline, it is necessary to continue the process of supplementation in the future, however, this paper is expected to be of great significance as the beginning of the research.

본 논문에서는 군용 항공기의 노후된 인터컴을 신규 인터컴 ICS로 교체하는 성능 개량을 제안하고 기체 내부 신규 인터컴 ICS와 연동 장비 간 연결을 위한 블록도 및 전기 배선 경로 방안을 간략하게 설계하여 제시하였다. 그러나 제시된 설계에 필요한 가이드가 부재하여 본 논문에서는 군용 항공기 표준감항인증 기준과 군용항공기 작업 지침서를 기준으로 QFD 기법을 적용하여 15종의 주요 설계 요소를 도출하였다. 결과적으로 본 논문에서 제안된 연동 블록도와 배선 경로, 그리고 도출된 15종의 전기 시스템 주요 설계요소는 향후 노후된 군용 인터컴 성능개량의 전기 시스템 설계 가이드로서 적용 가능함에 그 의미가 있다.

This study reviewed selected specific windows and reviewed the window performance certification criteria including KS F 2278 and KS L 9107 and analyzed the change in performance based on the change of area. This study also compared the heating and cooling loads of an apartment house applied with window performance reviewed in consideration of insulation and SHGC performance and actual size based on KS F 2278. The analyzed window was a double window composed of aluminum and PVC and the building was the apartment house model of 141 ㎡. The analysis results were as follows. First, as the window glass's thermal performance is superior to frame, the performance degraded in reduced area. In case of selected window, the 1 m × 1m window's thermal performance and SHGC decreased by 35% and 37% respectively compared to 2 m × 2 m window. Secondly, in the comparison of performance for increasing area with 2 m × 2 m and 3 m × 3 m windows, the 3 m × 3 m window's thermal performance and SHCG increased about 14%. Third, in the comparison of heating and cooling loads of the analyzed model considering the apartment house model applied with window performance derived from KS F 2278 and actual figures, the model's total heating and cooling loads increased by 33% with cooling decreasing by 36% and heating increasing by 77%. Above analysis results show that evaluation of window performance based on criteria such as KS F 2278 and KS L 9107 may lead to distortion of performances different from actual products. Thus, it is necessary to suggest new evaluation criteria.

한국 정부의 중소기업 육성정책은 대기업에 대해 중소기업을 보호하고 육성한다는 전통적 정책 기조를 탈피하여 중소기업 성장 기반 확충 및 고도화를 통한 혁신형 중소기업 육성 쪽으로 변모하고 있다. 본 연구는 혁신형 중소기업을 대상으로 하여 기업의 연구개발 역량과 벤처기업 인증 획득이 글로벌 기술경쟁력 강화에 유의한 영향을 미치는가를 자원기반이론(resource-based theory) 및 자원의존이론(resource dependence theory)을 통해 설명해 보고자 한다. 자원기반이론에 따르면 기업이 보유하고 있는 유·무형 자원 및 연구개발 역량의 차이에 따라 기술혁신 활동이나 기술혁신의 성과가 결정된다. 한편 자원의존이론에서는 중소기업을 정책적으로 지원하기 위한 정부의 인증제도는 혁신에 필요한 유·무형 자원에 대한 접근성을 높임으로써 중소기업의 혁신 활동과 혁신성과에 긍정적으로 작용한다고 주장한다. 본 연구는 연구개발 역량과 정부의 벤처인증이 글로벌 기술경쟁력에 미치는 직접 효과를 살펴보는 것에서 한발 더 나아가 중소기업이 개발한 주력제품 수명주기의 조절 효과를 살펴보고자 하였다. 여기서 조절 변수로써 제품의 수명주기는 연구개발 역량과 벤처기업 인증의 경쟁력 강화 효과에 상반되는 영향을 미칠 것으로 예상된다. 중소기업 기술 통계조사(2020) 자료에 기반한 실증 연구는 연구개발 역량과 벤처기업 인증의 글로벌 기술경쟁력에의 직접 효과와 제품수명주기의 상반된 조절 효과를 지지한다. 내부자원 활용의 기술경쟁력 효과는 제품수명주기가 길 때 커지는 반면 벤처인증을 통한 외부자원 활용의 기술경쟁력 효과는 제품수명주기가 짧을 때 커진다는 연구 결과는 연구개발, 기술혁신, 그리고 경영성과 간의 관계를 연구하는 데 있어 제품수명주기가 중요한 맥락 변수로 고려되어야 함을 시사한다. 또한 제품의 수명주기가 비약적으로 짧아지고 있는 글로벌 경쟁환경에서 업력과 규모에 있어 이중의 불리함을 극복해야 하는 혁신형 중소기업이 글로벌 기술경쟁력을 확보해 나가기 위해서는 내부적 연구역량 강화뿐 아니라 외부 자원의 확보 전략에도 집중해야 함을 시사한다.
