정진우,심이삭,윤상범,서정현 한국인터넷방송통신학회 2023 International Journal of Internet, Broadcasting an Vol.15 No.4

In this paper, we have undertaken a comprehensive investigation into the current state of anti-drone technology due to the increasing concerns and risks associated with the widespread use of drones. We carefully analyze anti-drone technology, dividing it into three crucial domains: detection, identification, and neutralization methods. This categorization enables us to delve into intricate technical details, highlighting the diverse techniques used to counter evolving drone threats. Additionally, we explore the legal and regulatory aspects of implementing anti-drone technology. Our research also envisions potential directions for advancing and evolving anti-drone tech to ensure its effectiveness in an ever-changing threat environment.

딥러닝 기반의 야간 주행 환경에서의 전동 킥보드 헬멧 감지

정진우,김다운 대한전기학회 2022 전기학회논문지 Vol.71 No.10

As the use of electric kickboards has increased recently, the frequency of safety accidents is also increasing. Even though the government amended the road traffic law to make it compulsory to wear a helmet, the helmet-wearing rate is still remarkably low. In this work, we propose a novel method to monitor and detect whether a user of an electric kickboard is wearing a helmet through a deep learning-based object detection network, thereby increasing the helmet-wearing rate. For continuous driver monitoring, the proposed method captures the user's face in a front view using the user's mobile phone attached to the kickboard. In addition, to handle both day and night driving conditions, various image conversion, enhancement, and augmentation techniques were considered and evaluated. The experimental results showed the feasibility of the proposed method

부정경쟁방지법상 오인야기행위에 관한 규정의 개선방안에 대한 고찰 - 일본법과 비교를 중심으로 -

정진우 한국지식재산학회 2023 産業財産權 Vol.- No.74

Korea Unfair Competition Prevention Act Stipulates Misleading such as an act of causing confusion about the source of origin, an act of causing confusion about the source, an act of causing confusion about the good’s information. However, there is a concern that unnecessary confusion may arise in the interpretation and application of the law because each provision is applied superimposedly in the interpretation of the law and the judgment of the court in relation to the above misleading act provisions. In addition, services are excluded from the application of the law even though the proportion of services in the national economy has increased. However, in the case of the Japanese Unfair Competition Prevention Act, which cites most of the regulations at the time of enactment of the Korean Unfair Competition Prevention Act, unnecessary confusion is prevented by integrating misleading acts. And Service is also added to the protection target. Therefore, in this paper, the Japanese Unfair Competition Prevention Act and the Korean Unfair Competition Prevention Act were compared and reviewed to suggest ways to improve the regulations on misleading. first of all a plan to integrate legal provisions was proposed. Among the provisions of misleading, an act of causing confusion about the source of origin is included in the act of causing confusion about the place of production, manufacture or processing when the provision is interpreted and applied and It's hard to apply each provision separately and the court ruled that an act of causing confusion about the source of origin is included in the act of causing confusion about the place of production, manufacture or processing. so, This paper presented a plan to integrate the rules of misleading. In addition, despite the increase in the proportion of services, services are still not included in the protection list for misleading acts, so a plan was proposed to add services to the protection list.

볏붉은잎 추출물의 돼지 세균에 대한 항균효과

정진우,정찬우,김정태,양원준,안미정,김병학,김주아,신태균 한국동물위생학회 2009 韓國家畜衛生學會誌 Vol.32 No.4

Interest in marine organisms as potential sources of bioactive agents has increased in recent years. The red seaweed, Callophyllis (C.) japonica, is abundant in the coastal regions of Jeju Island in South Korea. A previous study shows that C. japonica extracts have antioxidant activity and radioprotective effects. In this study, an methanol extract of C. japonica was tested whether it has antibacterial effects against porcine bacteria. the in vitro antibacterial activities of 80% methanol crude extracts prepared from the C. japonica were tested for inhibitory activity against the Escherichia (E.) coli (S175), Enterococcus (E.) faecium (ATCC 51558), Salmonella (S.) Typhimurium and Staphylococcus (S.) aureus (ATCC 25923) using broth dilution method. All organisms were incubated in brain heart infusion (BHI medium) containing 1% extract at 0, 4, 8, 12 and 24 hrs. Suckling piglets were fed an experimental diet supplement with 1% C. japonica for 1 week. And the change of fecal coliform bacteria were examined after supplement of C. japonica for 1 week. The inocula containing 102-103CFU/ml of each organism were used. The extracts of C. japonica were shown to be antibacterial effects on all bacteria tested. The CFU value (6.3×108CFU/ml) of C. japonica for E. coli was decreased 30% compared with vehicle controls (9.0×108CFU/ml) after 8 hrs incubation. For E. faecium was inhibited proliferation rate about 68% at 4h, 81% at 8 hrs and 76% at 12 hrs after incubations, respectively. For S. Typhimurium was inhibited proliferation rate about 96% at 4h, 90% at 8 hrs and 72% at 12h after incubation with extracts of C. japonica. For S. aureus was inhibited proliferation rate more than 90% each time courses. Conclusively, a red seaweed extract of C. japonica was found to be effective against a number of gram negative and gram positive bacteria such as E. coli, E. faecium, S. Typhimurium, and S. aureus. The number of coliform bacteria was increased in the 1% C. japonica treated group, as compared to those of controls. This result suggests that C. japonica extracts be added as an effective natural antibacterial agent. The precise mechanism of antibacterial effects and its application on swine industry remains to be further studied.

기생소자에 의한 다이폴 배열 안테나의 방사특성 개선에 관한 연구

정진우 대한전자공학회 2019 전자공학회논문지 Vol.56 No.11

The radiation characteristics of an array antenna are affected by the distance between radiating elements. When the distance between radiating elements is increased, the half power beam width is decreased, thus, the directivity of an array antenna is increased. However, when grating lobes(except main lobe) are included in visible region according to increase the distance between radiating elements, the directivity is dereased. Therefore, an array antenna has the threshold for the distance between radiating elements. In this paper, we analyze the radiation characteristics for a dipole antenna with parasitic element, and studied the improving method of the radiation characteristics for a dipole array antenna using parasitic elements in the condition over the threshold. 배열안테나의 방사특성은 방사소자간 간격에 영향을 받는다. 배열된 방사소자간 간격이 증가할수록 배열안테나 주빔의 반치각은 감소하여 지향성이 개선된다. 그러나 만약 방사소자간 간격이 가시영역 내 주빔 이외의 그레이팅 로브가 포함될 때까지 증가하면 지향성은 감소하게 된다. 따라서 배열안테나는 방사소자간 간격에 관한 제약 조건을 갖는다. 본 논문에서는 기생소자에 따른 다이폴 안테나의 방사특성 변화를 분석하였다. 분석 결과를 기반으로 방사소자간 간격에 관한 제약 조건 이상의 구성 조건을 갖는 다이폴 배열 안테나에 있어, 기생소자에 의한 방사특성 개선에 관하여 연구하였다.

좌심방 점액종 제거 후 재발한 우심방 점액종(재발한 점액종) -1예 보고-

정진우,송현,강신광,제형곤 대한흉부외과학회 2007 Journal of Chest Surgery (J Chest Surg) Vol.40 No.4

33세 남자가 심와부 불편감을 주소로 내원하여 흉부컴퓨터단층촬영과 심초음파에서 좌심방 내 점액종으로 수술적 절제하였다. 12개월 후 외래추적 검사에서 첫 번째 수술과 관계없는 부위인 우심방 내 점액종이 발견되어 재수술하였으며 10개월간 재발 없이 지내고 있다. 우리 나라에서는 좌심방 내 점액종 제거 후 재발된 좌심방 내 점액종은 보고된 적이 있지만, 우심방에 재발된 경우는 보고된 바가 없어 치험례를 보고한다.

인터넷상에서의 이동 호스트를 위한 차별화서비스 설계

정진우,천정훈,원유재,강현국 에스케이텔레콤 (주) 1999 Telecommunications Review Vol.9 No.3

본 논문은 인터넷 환경에서 이동 사용자들에게 QoS(Quality-of-Service)를 제공하기 위한 통합 모델을 제안하였다. IETF에서 제안한 DiffServ와 IntServ는 고정 호스트와 정적인 환경을 바탕으로 설계 되었기 때문에 이동 호스트와 이동 환경에는 부적합하다. 또한 IntServ(Integrated Services)와 RSVP(Resource Reservation Setup Protocol)는 확장성 문제때문에 거대한 인터넷에 적용할 수 없다는 단점을 지니고 있다. 따라서, 제안된 모델은 이동 서비스를 위해서 IETF에서 제안한 Mobile IPv4(MIPv4)에 기반을 두고 있으며, QoS제공을 위하여 IETF에서 차별화 서비스(Differentiated Service)로제안한 DiffServ에 바탕을 두고 설계하였다[1],[3]. MIPv4 환경에 DiffServ를 적용하기 위해서 기존의 MIPv4 메시지 형식을 수정하였으며, 추가적인 기능과 동작을 정의하였다. 본 논문에서는 상태 정보의 수가 적은 DiffServ의 장점을 유지하기 위해서 대부분의 추가적인 기능을 MIPv4의 에이전트에 추가하고, 호환성을 제공할 수 있도록 설계하였다.
