차량 탐지와 차량 추적 기술은 교통관리 시스템, 자율주행 자동차 시스템 및 이를 응용한 보안 감시 시스템, 군사 작전 및 안전 등 다양한 산업 분야에서 활용되고 있다. 본 논문에서는 차량 탐지는 YOLOv7 모델을, 차량 추적은 DeepSORT 알고리즘을 사용하여 도로의 차량들에 대해 탐지 및 추적을 순차적으로 진행하였다. 실험환경은 차량 탐지 데이터 셋(dataset)을 직접 라벨링(labeling) 하여 실험하였고, 차량 추적은 차량 탐지에서 학습해서 얻은 체크포인트(checkpoint) 모델을 가중치로 설정하여 실험을 진행하였다. 차량 탐지 실험결과는 validation 과 test 에서 높은 정확도를 확인할 수 있었고, 차량 추적은 Namsa 비디오 및 Seohaegyo 비디오에서도 차량 추적이 잘 되고 있음을 확인할 수 있었다.

최근 자동차와 항공 산업에서는 승객들의 편의에 맞추어 엔터테인먼트 서비스를 선보이고 있다. 선행 연구에 따르면, 이동 시간대 스마트폰으로 프로그램을 이용하는 동기로는 '오락용'(19.8%), '소통용(SNS)'(18.8%), '정보용'(15.0%), '게임용'(6.8%)로 전체의 60.4 %를 차지한다. 이는 콘텐츠와 커뮤니티 이용 및 정보탐색 등으로 이동 중 지루한 시간을 해소한다는 유의미한 통계를 보여준다. 해상 분야에서도 정보와 오락 기능을 결합해 편리한 항해를 지원할 필요가 있다고 사료된다. 본 논문은 인터넷 통신이 어려운 선박에서도 무선 통신망을 이용하여 미디어 콘텐츠 및 커뮤니티 활성화뿐만 아니라 안전사고 발생 시 신속하고 정확한 정보 전달 등을 목표로 삼는 선박 인포테인먼트 시스템을 제안하고자 한다.

소프트웨어 소스코드는 크게 오픈 소스와 상업용 비공개 소스로 구분될 수 있다. 소스코드는 자동차 조립라인과 같이 소프트웨어를 무제한 생산이 가능한 지식집약적인 부가가치 산업이다. 본 논문에서는 오픈-소스 코드에는 디지털라이센스를 이용한 저작권을 표현하고, 비공개-소스 코드는 보안 컨테이너 역할을 수행하는 크립텍스 모델을 제안한다.

The machinery industry provides infrastructure to many manufacturing industries and it has strong influences on performance and quality of products. However, Korean economic growth has been constantly causing the korean general machinery industry to significantly depend on Japan. To solve this problem, many industrial policies have been tried. In this paper, we divide the value chain of general machinery industry into four steps; technology development step, manufacturing step, marketing step, and after-sales management step. We study the relationships between each of these steps and the awareness of dependency on Japan. For empirical analysis we surveyed 207 domestic companies in general machinery industry. The findings are that the three factors, technology development competency, marketing competency and after-sales management competency have significant relationships with dependence on Japan. Manufacturing competency is not a significant factor. As control variables, the type of manufacturers has effect on dependency on Japan. The company size, the kinds of products and technology levels of products don't have effects on the relationship between the four steps of the value chain and dependency on Japan. To overcome the trade imbalance with Japan in the general machinery industry, we recommend to develop technology development competency, marketing competency, and after-sale management competency. Also we need to adopt industry supporting policies, not depending on all three control variables of company sizes, the kinds of products and the technology levels of products, but depending on the type of manufacturers.

The Korea's automotive industry have been achieved remarkable growth with many original models for over 28 years since the first original model Pony had developed. And most of the early models were licensed from the other country's makers. Now it is independent with our own technologies and designs, and the automobile is one of the major exporting products of Korea. In the early times the basic design concept of a passenger car didn't reflect the characteristics of the way of domestic life, but today's Korean developed cars have speciffic characters those are distinguished to others not only in the overall body shape but also in the package layout. And it is considered that the Korean cars would have different characteristics to the others in the future. These changes would come from the ways of life of the nations characteristics and they would influence to technologies of development. And the influence would be resulted as another type of sedan which has much differences to the current sedans. The main elements and the reasons for the 'post sedan' have been observed to specify the characters of the future Korean sedan in this research.

The automotive industry is facing a paradigm shift, changing from owning to sharing and from manufacturing to service. However, it is hard to conclude that the economic value of smart mobility service is always positive to users. Cost related to owing or share a vehicle is very hard to estimate from the perspective of potential users as well as the benefit of the service. Focusing on the cost side of the story, this study develops a cost estimating model based on three main factors: electrification, advanced driving assistant systems (ADAS) function, and participation of ride-sharing service. As a result of the model analysis, low cost was estimated as a result when receiving cost benefits such as electrification and ride-sharing participation. Various factors were analyzed through sensitivity analysis also. These results can provide useful insights into the cost prediction and strategies for potential users and manufacturers on smart mobility service market.

Pedestrian facilities encompass pedestrian roads, stairs, and queuing areas exclusively designed for pedestrian use. The Korean Highway Capacity Manual provides guidelines for analyzing the capacity and level of service of pedestrian facilities. However, there is a lack of analysis methods tailored specifically for pedestrian facilities. Therefore, in this study, we introduced a new standard of pedestrian space to account for changes in the Korean body ellipse. Furthermore, based on this newly defined pedestrian space, we proposed a new standard value for the level of service of queuing areas. The results of on-site surveys confirmed that the proposed level of service can effectively reflect the actual walking situation.

In the rapid technological development of artificial intelligence (AI), electric vehicles, and robots based the fourth industrial revolution, semiconductors determine the core performance, and semiconductor competitiveness is directly related to national competitiveness. However, the Korean semiconductor industry has continuously weakened its competitiveness in the system semiconductor field, excluding memory semiconductors, so in this study, a new smart contract basedblockchain business model to engage the global market, which is the most urgent need for the growth of Korean fabless system semiconductor industry in recession. F-SBM (Fabless-Smart contract based Blockchain Model) proposed. In this study, through the new F-SBM, it was verified how to engage new customers for fabless firms through smart contract based consortium blockchain regarding technology, economy, and reliability items of fabless. This model has great significance in improving the high entry barriers to engaging new customers for the long-cherished desire of the Korean fabless system semiconductor industry and deriving new growth solutions.

Throughout all industries, eco-friendliness is being promoted worldwide with focus on suppressing the environmental impact. With recent international environment policies and regulations supported by government, the electric vehicles demand is expected to increase rapidly. Battery system itself perform an essential role in EVs technology that is arranged in cells, modules, and packs, and each of them are connected mechanically and electrically. A multifaceted approach is necessary for battery pack bonding technologies. In this paper, pros and cons of applicable bonding technologies, such as resistance welding, laser and ultrasonic bonding used in constructing electric vehicle battery packs were compared. Each bonding technique has different advantages and limitations. Therefore, several criteria must be considered when determining which bonding technology is suitable for a battery cell. In particular, the shape and production scale of battery cells are seen as important factors in selecting a bonding method. While dealing with the types and components of battery cells, package bonding technologies and general issues, we will review suitable bonding technologies and suggest future directions.

The researches on driver assistance systems that can prevent an accident have been actively performed due to social issues of traffic accidents with development of vehicle industry in recent. It is required for researchers to develope systems which assist driver's perception and judgment when considering that over 70% of traffic accidents occur by drivers' carelessness and 75% of the total accidents occur at the speed of less 29km per hour. In this paper, we implemented a front and rear vehicle monitoring system that monitors distance in real-time from a vehicle to obstacles at the low-speed or back-ward driving. The implemented system consists of a high angle ultrasonic sensor with distance detection of 10m and 10-degree angle, a wide angle ultrasonic sensor with the detection distance of 3m and a 180-degree, and a ATmega128 chip of ATmel company.
