The DAPA (Defense Acquisition Program Administration) has been operating the DQ mark certification since 2012 to certify the superior technology and quality of munitions. On the other hand, the current DQ mark certification can not directly provide DQ mark certification to software because it is impossible to verify the quality of software alone. Therefore, this study analyzed domestic/overseas software quality evaluation/certification standards to find a way to verify the quality of software in the DQ mark certification. Among them, the method of applying the GS certification according to the international standard ISO/IEC 25000 series to the DQ mark certification was suggested as an improvement plan, and DQ mark certification verified the quality of software and provided certification. An attempt was made to expand the certification scope of DQ mark certification. This paper proposes that the DQ mark can be given to the system software by introducing GS certification to the DQ mark certification. To this end, an improved procedure for omitting the factory audit and verification by submitting a GS certificate for product evaluation is proposed. This is expected to increase defense exports using the granted DQ mark and improve the quality of defense software products through GS certification.

The character strings on chips and components are so tiny and numerous that it is a very difficult work for people to perform. In paper, this we propose a mark automatic checking system, which will determine whether chip is wrong-mark or not by recognizing characters on chips. Lots of faulty detection conditions and template matching methods are used to inspect the faulty mark items. The faulty detection classifies conditions as five kinds-darkness, matching, area, broken and branch. A series of experimentation shan that the method proposed here am offer an effective way to determine wrong-mark on chips.

The gate mark in injection molded part is a kind of surface defects. The formation of gate mark has been investigated in this study. SEM photographs and surface roughness have been examined to study gate mark. The specimens were molded for various injection conditions, such as injection temperature, mold temperature, and injection speed. Gate diameter and mold surface condition were also molding variables. Gate marks were reduced as injection speed and mold temperature increased. Gate diameter and injection temperature did not affect the gate marks. No etching of mold surface showed no gate marks for any molding conditions.

본 논문은 고리 1호기 원자력발전소를 기준발전소로 하여 개발된 PRE-MARK 소개 및 PRE-MARK을 기반으로 개발된 노심모델의 결과를 제시하고자 하는 것을 주된 목적으로 하고 있다. 노심 모델개발에는 REMARK 모델 프로그램을 기반으로 개발된 PRE-MARK를 이용하였으며, PRE-MARK의 주요 특징으로는 노심모델 입력자료를 노심설계코드 및 Lattice 코드로부터 자동으로 생성하며여 GUI 기반으로 변경된 REMARK으로 입력하여 노심모델을 구동함과 동시에 실시간으로 중요 변수의 현재 값들을 그래프로 도시해줌으로 조율 (Tuning) 상수를 용이하게 결정할 수 있도록 하는 것이다. 또한 BOL 및 EOL에서 HFP 평형 Xenon조건에서의 제어봉 위치에 따른 제어봉가(Rod worth)를 고리 1호기 20주기 NDR (Nuclear Design Report)과 비교하고, 원자로정지 이후 BOL, MOL 및 EOL에서의 시간에 따른 Xenon의 반응도 영향을 비교함으로 개발된 모델의 건전성을 입증하였다.

We developed the playback control software for a high-speed playback system which is a component of the Korea-Japan Joint VLBI Correlator (KJJVC). The Mark5B system, which is a recorder and playback system used in the Korean VLBI Network (KVN), has two kinds of operation mode. That is to say, the station unit (SU) mode, which is for the present Mark4 system, and the VSI mode, which is for the new VLBI standard interface (VSI) system. The software for SU is already developed and widely used in the Mark4 type VLBI system, but the software for VSI has only been developed for recording. The new VLBI system is designed with a VSI interface for compatibility between different systems. Therefore, the playback control software development of the VSI mode is needed for KVN. In this work, we developed the playback control software of the Mark5B VSI mode. The developed playback control software consists of an application part for data playing back, a data input/output part for the VSI board, a module for the StreamStor RAID board, and a user interface part, including an observation time control part. To verify the performance of developed playback control software, the playback and correlation experiments were performed using the real observation data in Mark5B system and KJJVC. To check the observation time control, the data playback experiment was performed between the Mark5B and Raw VLBI Data Buffer (RVDB) systems. Through the experimental results, we confirmed the performance of developed playback control software in the Mark5B VSI mode.

The purpose of this study was to identify the causal relationship between the brand, the brand equity and brand equity of a tourist destination. The effect of love mark on self identification is that the relationship between love mark performance and self-identification time is significant, and that of love mark is in the order of self identification. Trust mark of love mark has a significant relationship with self identification. The relationship between brand intimacy and brand quality and the relationship between trust and brand quality were significant in relation to the brand mark, but brand mark was not significant. In addition, in the relationship between brand value and love-mark, there is a significant relationship between performance and brand value, relationship between intimacy and brand value, and performance is not significant in brand value. There was a significant relationship between gender and behavioral intention. The relationship between gender identity and behavioral intention was positively related to brand equity.

Traffic accidents due to excessive speed frequently occur in places where traffic signal controllers are installed, places where sharp curves exist, or places where the traffic signal cycle does not match the current time. These traffic accidents cause economic loss due to the destruction of road facilities and structures, and cause a big problem of increasing the number of traffic accident deaths. When a traffic accident occurs, leaving a tire mark before or after a car crash, pre-collision speed of the car is calculated using the law of conservation of momentum or the skid mark formula. In the skip skid mark generated in ABS brake vehicles and the combshaped yaw mark generated by tire trace caused by lateral sliding, there is a difference of 30-40% in the reliability of the vehicle speed calculated by the smite mark. In this paper, we propose an algorithm that can improve the calculation reliability in vehicle speed by using skid marks in order to compensate for this problem. In addition, we present an intelligent speed calculation algorithm for traffic safety and a computer simulation in order to prevent traffic accidents by estimating the speed of a vehicle, using Skid marks, Yaw marks, and ABS brake characteristics and fuzzy rules.

KC Mark is one of the country's integrated legal force to the minimum mandatory certification mark system for safety. That is absolutely needed for manufacturing and sales of goods in Korea. This thesis intended to see what is prevalent for both imports and domestic products for illegal and defect and rebuild the ecosystem as soon as possible for the healthy development through public awareness. In this theses point out the seriousness of the problem based on the various kinds of press releases, data of KCA(Korea Consumer Agency), MOTIE(Ministry of Trade, Industry and Energy) and KCA(Korea Customs Service) to the problem of certification system of KC mark and propose a solution to that issue. This study is considered to make befit the nation's place in the world and sustainable development is possible about the system of certification KC. This study expect more research on this issue in order to make enhance the confidence of KC mark.
