본 논문에서는 단일 급전부를 갖는 레이다 디턱테용 X 밴드(10.525 GHz) 1×2 배열 안테나와 K 밴드(24.15 GHz) 3×6 배열 안테나를 제안한다. 제안된 배열 안테나의 왼편에는 X 밴드 배열 안테나가 있고 오른편에는 K 밴드 배열 안테나가 있다. 두 개의 배열 안테나는 하나의 전송 선로를 통해 급전이 되고, stub가 각 배열 안테나의 앞부분에 있다. 서로 다른 동작 주파수를 갖는 배열 안테나를 일반적인 T-junction을 이용하여 하나의 전송 선로로 급전할 경우, 서로 영향을 주어 배열 안테나의 특성이 크게 바뀌게 된다. 이러한 영향을 차단하기 위해 open, short 특성을 이용하여 stub를 설계하였다. 먼저 각 배열 안테나에 stub가 연결되어도 안테나 특성이 바뀌지 않는 것을 확인하였고, 최종적으로 두 개의 배열 안테나를 연결하여 하나의 전송 선로로 급전을 하여도 성능이 바뀌지 않는 것을 확인하였다. 측정한 이득은 X 밴드에서 6.47 dBi, K 밴드에서 13.07 dBi로 시뮬레이션 결과와 잘 일치하였다. In this paper, the X(1×2, 10.525 GHz) and K(3×6, 24.15 GHz) bands patch array antenna having single feed line for radar detector applications is proposed. The left side of the proposed array antenna is X band array antenna and the right is K band array antenna. Two array antennas with two stubs located in the front of antennas are fed through one transmission line. If the array antennas which have the different resonance frequency are fed by one transmission line using general T-junction, it interferes each other and the array antenna lost its character. Therefore, to prevent these interferences, two stubs using open and short property of stub are designed. First of all, the performances of array antenna weren"t changed when each array antennas were connected with the stub and in the end, it is found out that it was the same when the two array antennas were combined and feed through the one transmission line. The measured gain at X band is 6.47 dBi and measured gain at K band is 13.07 dBi. The experimental results agree well with the simulated ones.

This work presents an effective overlay multicast tree construction algorithm for synchronized real-time media multicast service over the Internet. The proposed algorithm is designed to minimize delay variance among group members to provide the synchronized service as well as average delay of group members in order to support the service in real-time. Basically, of orthogonal genetic algorithm is employed to obtain the near optimal tree with a low computational complexity since the given problem is NP-complete. Finally, experimental results are provided to show the superior performance of the proposed algorithm. 본 논문은 인터넷 상에서 동기화된 실시간 미디어 멀티캐스트 서비스에 적합한 오버레이 멀티캐스트 트리를 구성하는 알고리즘을 제안한다. 제안하는 알고리즘은 멀티캐스트 송신 단에서 각 종단 시스템 사이의 전송 지연에 대한 평균과 변이를 최소화하는 트리 구성을 찾는다. 그러나 위의 문제는 NP-완전하므로, 이러한 문제의 계산 복잡도를 낮추면서, 근사해를 찾기 위한 방법으로 OGA (Orthogonal Genetic Algorithm)을 이용하였다. 실험 결과에서 제안하는 알고리즘이 기존 알고리즘에 비해 통기화된 실시간 미디어 데이터 전송을 위한 효과적인 트리를 구성한다는 것을 보인다.

주현철,이주형,임종원,이재희,강인석,Hyun-Chul Joo,Ju-Hyeong Lee,Jong-Won Lim,Jae-Hee Lee,Leen-Seok Kang 한국토지주택공사 토지주택연구원 2023 LHI journal of land, housing, and urban affairs Vol.14 No.3

최근 건설산업 분야에 BIM 기술의 활용이 보편화되면서 3D 모델과 실제 시공 부위의 오류 확인 등을 위해 다양한 객체 탐지 알고리즘들이 활용되고 있다. 객체 탐지 기술은 건축물, 교량, 터널 등 건설시설물의 종류에 따라 객체 특성이 상이하므로 객체 탐지 기술도 적절한 방법을 사용할 필요가 있다. 또한 객체 탐지를 위해서는 초기 객체 이미지가 있어야 하며 이를 위해서도 드론, 스마트폰 등 다양한 방법으로 이미지 취득이 가능하다. 본 연구에서는 철도와 도로 시설의 터널 부위에 대하여 초기 이미지 구축을 위해 터널 내부 촬영에 최적화된 360° 카메라를 이용하여 이미지를 촬영하고, 촬영된 이미지로부터 실제 객체를 탐지하기 위한 객체 탐지 방법론으로 YOLO 알고리즘, SSD 알고리즘 및 R-CNN 알고리즘을 적용하여 방법론별 객체 탐지의 정확도를 비교 분석한다. 분석 결과 Faster R-CNN 알고리즘이 SSD, YOLO v5 알고리즘에 비해 높은 인식률 및 mAP 값을 가졌으며 인식률들의 최소·최대 값의 차이가 작아 균등한 검측 능력을 나타냈다. 이러한 연구는 철도와 도로 시설공사에 BIM 적용이 확산되고 있는 점을 고려하면 360° 카메라의 활용 방법 확대와 유지보수를 위한 터널 시설 부위의 객체 탐지 방법론 적용에 활용될 수 있다.

Objective : Recently interest of fermented herb medicine has increased in Oriental medicine. Herb medicine fermented in a proper condition resultingly has better or new virtue by microbe. This study was designed to compare the anti-inflammatory effects of herbal decoction and fermented herbal decoction in Hwangnyeonhaedok-tang (Huanglian fiedu-tang; HHT). Methods : The effects of HHT and FHHT on anti-inflammation were measured by production of NO and pro-inflammatory cytokine productions including TNF-${\alpha}$ and IL-1${\beta}$, IL-6 in LPS induced RAW 264.7 cells. Results : 1. Cell viability in three doses of HHT extract (0.01, 0.05 and 0.10 mg/ml) and two doses of FHHT extract (0.01, 0.05 mg/ml) was more than 70% and 80% each. 2. In RAW 264.7 cells, LPS displayed significant stimulatory effects on the production of NO. However, both HHT, FHHT showed significant inhibitory effects on the production of NO. 3. Pre-treatment by HHT in a various concentrations (0.01, 0.05, 0.10, 0.50mg/ml) reduced the elevated production of TNF-${\alpha}$, IL-1${\beta}$, IL-1${\beta}$ mRNA, IL-6 mRNA. More than 0.05mg/ml concentrations of HHT reduced the production of IL-6. And TNF-${\alpha}$, IL-1${\beta}$ level of mouse serum reduced in a various dose(0.1, 0.5, 1.0g/kg). 4. Pre-treatment by FHHT in a various concentrations (0.01, 0.05, 0.10, 0.50mg/ml) reduced the elevated production of TNF-${\alpha}$. More than 0.05mg/ml concentrations of FHHT reduced the expression of TNF-${\alpha}$ mRNA. 0.1, 0.50mg/ml concentrations of FHHT reduced the production of IL-6. And IL-1${\beta}$ level of mouse serum reduced in a various dose(0.1, 0.5, 1.0g/kg). Conclusions : These results indicated that both HHT and FHHT could have anti-inflammatory capacity by inhibiting the production of NO and cytokines in vitro. But HHT has more strong anti-inflammatory effects than that of FHHT in broad outlines.

Emerging of wireless sensor networks results in several modeling and design issues on the network simulations. In previous works, most researchers have used three evaluation approaches such as analysis method, computer simulation and real test-bed measurement in order to verify the performance of wireless sensor networks. Among these approaches, analysis method is widely used since the other approaches have significant drawbacks such as limitation of network power, computational problem of distribute processing and complication of debugging process. However, the analysis method also shows poor performance when it deals with complex operations in huge wireless sensor networks. Thus, in this paper, we design and develop SMAC and AODV protocols by using Ptolemy tool in order to improve the simulation performance. The developed Ptolemy actor can be easily adapted to compare and evaluate the various protocols for wireless sensor networks. 최근, 무선 센서 네트워크의 출현은 네트워크 디자인에 많은 이슈를 가져왔다. 전통적으로, 유/무선 네트워크의 성능 측정을 위해서 분석적 접근, 컴퓨터 시뮬레이션과 실제 테스트베드상의 측정3가지 방식을 이용하였다. 그렇지만 네트워크의 파워 제한, 분산된 처리와 장애 처리등과 같은 제한 때문에 알고리즘이 복잡하여 일반적으로 분석적 접근을 이용하여 성능을 측정하였다. 하지만 이러한 분석적 접근은 센서 네트워크의 복잡한 동작환경에서 성능측정에 한계를 가지고 있다. 이러한 제약을 극복하기 위해 본 논문에서는 Ptolemy Tool를 이용하여 효과적인 무선 센서 네트워크 시뮬레이션의 성능평가를 위하여 MAC계층의 SMAC와 네트워크계층의 AODV를 개발하고 실험하였다. 구현된 Actor는 센서네트워크내 다양한 프로토콜들의 성능비교에 용이하게 활용될 수 있다.
