무선 멀티캐스팅에서 이동 호스트가 같은 멀티캐스트 그룹 기지국으로 이동할 때 새로운 기지국으로부터 원하는 데이터를 즉시 수신하기 위해서는 기지국들간에 데이터 전달에 대한 정보교환이 필요하다. 그러나 기존의 기법들은 정보 교환시 소요되는 전달 시간과 오버헤드가 많아 비효율적이다. 또한 이동 호스트가 멀티캐스트에 참여하지 않는 기지국으로 이동할 때 전송지연을 피하기 위해서는 현재 기지국이 주변 기지국들에게 데이터를 미리 전달하는 사전 전달 기법을 사용한다. 그러나 기존의 사전 전달 기법에서는 이동호스트들이 짧은 시간 간격을 두고 연속 이동할 경우 현재 기지국이 같은 주변 기지국들에게 같은 데이터를 재전송하게 되어 중복 데이터가 발생할 수 있다. 본 논문에서는 이와 같은 문제를 해결하기 위한 기법으로 새로운 정보교환 기법인 IES(Information Exchange Scheme)를 제안한다. 제안된 IES에서는 멀티캐스트 그룹에 참여하는 기지국들이 국부적인 정보교환을 함으로써 필요한 시간과 오버헤드를 최소화하고 있다. 또한 IES에서는 이동 호스트의 연속적인 이동을 위해 주변 기지국들이 사전 전달받은 데이터를 일정기간 삭제를 보류함으로써 중복된 데이터 전송을 피할수 있다. 비용 산출과 시뮬레이션에 의해 기존 기법들과의 성능을 비교함으로서 제안된 기법의 성능을 확인한다. In a wireless multicasting when a mobile host moves to the new bate station being in the same multicast group it needs to exchange information about data delivery between base stations to receive data from the new base station at once. However it is inefficient to use the existence schemes because it takes too much time to exchange information and many overheads. The next, a mobile host moving to the base station not being in the same multicast group, the old base station will pre-forward data to neighboring base stations to avoid transmission delay. However, if other mobile hosts move at short interval, the old base station may retransmit the same data to the same neighboring base stations. In this paper we proposed called Information Exchange Scheme (IES). In IES in the same multicast grope the base stations exchange information locally so it takes the minimum time and overheads to use IES. Also in IES the neighboring base stations delay to delete data for continuous moving of other MHs. We also present how our scheme is efficient by producing cost ad simulating.

Objectives: The purpose of this review is to analyze the domestic study trends of clinical use of Digital Infrared Thermal Imaging (DITI) as a diagnosis instrument on obstetrics and gynecological diseases in Korean literature. Methods: We searched for clinical studies using DITI in the journal of Korean obstetrics & gynecology, National Digital Science Library, Research Information Sharing Service, Korean Medical Database up to May 2020. After searching studies, we selected studies and analyzed according to disease. Results: 18 clinical studies were published in two kinds of academic journals. There were 4 studies about dysmenorrhea and menopausal symptoms, 2 studies about postpartum disease and hypercryalgesia, 1 study about amenorrhea, premenstrual syndrome, leukorrhea, infertility, polycystic ovary syndrome and hot flush. Conception vessel was frequently used for DITI measurement, followed by stomach meridian. The temperatures of abdomen (CV4, CV12), face (HN3), upper and lower limb (PC8, LU4, LR3, ST32) were commonly measured. Conclusions: This study shows that DITI could be one of effective diagnosis instrument for obstetrics and gynecological diseases. More well-designed clinical studies using DITI will be needed.

MPLS 네트워크에서 DiffServ를 효율적으로 적용하기 위한 동적 흐름 수락 제어

임지영,채기준,Im, Ji-Yeong,Chae, Gi-Jun 한국정보처리학회 2002 정보처리학회논문지 C : 정보통신,정보보안 Vol.9 No.1

본 논문에서는 차세대 인터넷으로 진화할 수 있는 새로운 핵심 기술로 평가받고 있는 MPLS(Multiprotocol Label Switching) 네트워크에서 QoS를 제공하기 위하여 DiffServ(Differentiated Services)를 지원하는 동적 흐름 수락 제어를 제안한다. 제안 모델은 아웃 포트의 전송 가능한 용량을 계산하여 이 용량에 맞게 흐름을 받아들이고 패킷을 전송한다. 또한 QoS 라우팅 테이블을 위한 정보 교환으로 혼잡 지역을 알 수 있는 ingress LSR은 혼잡 지역을 배제한 경로로 패킷을 전송하게 한다 이렇게 함으로써 제안 모델은 DiffServ의 단점으로 인정되는 자원 낭비를 막고 자원을 효율적으로 관리하여 자원의 이용률을 높이고 서비스 받기 위해 네트워크에 진입하는 흐름의 수를 높일 수 있다. MPLS(Multiprotocol Label Switching) is regarded as a core technology for migrating to the next generation Internet. In this paper, we propose an dynamic flow admission control supporting DiffServ(Differentiated Services) to provide QoS in MPLS networks. Our proposed model dynamically adjusts the amount of admissible traffic based on transmittable capacity over one outgoing port. It then transmits the Packets while avoiding congested area resulting traffic loss. Ingress LSRs find out the congested area by collecting network state information at QoS state update for QoS routing table. Our Proposed model manages the resource efficiently by protecting the waste of resources that is a critical Problem of DiffServ and makes much more flows enter the network to be served.

이동 호스트에서 기지국으로의 데이터 전송 시 예상치 못한 기지국 전체 고장은 필연적으로 버퍼에 있는 데이터의 손실을 초래하고 적절한 손실 보상이 필요하다. 기지국의 고장시의 회복을 위한 기존의 기법들은 오버헤드가 많고 단순히 무선 링크 장애만을 고려하므로 기지 국 전체 고장에는 적합하지 않다. 유무선망 전체의 신뢰성 있는 전송을 위한 End to End 전송 방식도 비효율적으로 이동 호스트가 보상할 데이터 량을 알기 위해 필요한 기지국 버 퍼의 정확한 손실 정도를 알기 어렵다. 본 논문에서는 기존에 제안된 기법들의 문제점을 분 석하고 무선 ATM망에서 기지국 고장 시에 효율적으로 손실 보상을 하도록 하는 기법으로 CPS(Checkpoint Scheme)을 제안한다. CPS는 기지국이 버퍼의 출력 정보를 통보하여 고장 시에 이동 호스트가 seamless한 전송을 할 수 있도록 한다. 기존의 기법들과 시뮬레이션 및 비교 분석을 통하여 CPS의 효율을 증명한다.

Objectives: The purpose of this study was to investigate the effect on factors related the expression of aquaporins (AQP) and milk production after administration of Boheotang-gagam in lactating mice. Methods: The SKH-1 mice were randomly allocated to the control group which was administered with distilled water for two weeks after the parturition and the experimental groups such as, lactating+400G group (L400G) which was administered with Boheotang-gagam 400 mg/day, lactating+600G group (L600G) which was administered with 600 mg/day for two weeks after the parturition, and 400G+lactating+400G group (400G-L400G) which was administered with 400 mg/day for 3 weeks starting one week prior to parturition for experiment (n=6 per group). Results: 1. With regard to the immunohistochemical staining reaction for AQP1, AQP3, and AQP5, stronger immune response was also showed in mammary gland in all experimental groups as compared to the control group. AQP1 showed stronger immune response in the capillaries and venules which were located around the interlobular duct, while stronger immune response of AQP3 and AQP5 showed in the secretory alveolar epithelia and intralobular and interlobular ductal epithelial cells. 2. In the western blot, L400G group showed the most increased expression followed by L600G and then 400G-L400G group in AQP1. In AQP3, the order of expression density was observed as L600G, 400G-L400G and L400G group. Lastly, in AQP5, L400G group presented the most increased expression followed by L600G and 400G-L400G group. Conclusions: Boheotang-gagam would have the effect of increasing the lactation of mice after the birth by increasing the prolactin level and adjusting the expressionof AQPs and prolactin receptor in the mammary glands.
