This report describes Neural Tube Defects (NTDs) with Abdominal Wall Defects (AWDs) on the sibling of Yorkshire terriers. The NTDs and AWDs are rare serious congenital defects. The NTDs are neurulation abnormality that results from to failed transformation of the neurual tube by the incomplete closure of the embryonic neural plate. These dysraphic states range form mild to severe according to developmental malformation that include fusion defects of skull (crania bifida; CB) and fusion defects of vertebrae (spina bifida; SB). The AWDs are genetic defects that results from to failed formation of abdominal wall and cavity. These dysraphic states are omphalocele and gastroschisis. The 12-month dam was delivered by caesarian section and 4 littermate had obvious malformations. One male dead stillbirth fetus (L1) was revealed the extruded abdominal viscera, omphalocele. One female fetus (L2) was died within 1 hour after birth with defects of abdominal muscle upper umbilicus, gastroschisis. 3rd fetus (L3) was died within 36 hours after parturition and revealed a copious dermal and vertebral defects on the midline thorax, upper SB asperta. 4th fetus (L4) is still growing well now at 6 months but at the 2 week age, appears hairy nevus on the frontal cranium and dorsal thoracic portion. The radiograph of L1 and L2 are shown decrease bony density of calvarium and L3 was shown defect of spinose processes of the T9-T13. On our knowledge, this is first report of the SB and CB in Yorkshire terrier. And also sibling of NTDs with AWDs that has not previously been reported in the dog.

본 연구에서는 농업기반공사에서 구성한 AWDS (Agricultural Water Demand & Supply Estimation System: 농촌용수 수요공급량 산정시스템)를 기반으로 대상지역인 안고용수구역에 대한 정보를 추출하였다. 또한 이를 ArcGIS Hydro Data Model을 이용하여 유역의 공간객체와 하천 네트워크의 연관성을 부여하여 위상관계을 가지게 하였으며, 24개의 저수지, 18개의 양수장, 28개의 취입보 등 총 70개의 수리시설물의 네트워크를 모델링하였다. 이로 수리시설물의 공간위치를 가시적으로 표현하여 특정한 시설물 파악이 쉬우며, 하천망과 더불어 표현함으로써 순차적인 물수지의 체계를 이해하기 쉽도록 하였다.

Walking is not only an essential component of the human mobility, but also is a good exercise. Inability to walk freely can reduce an individual's quality of life and independence substantially. Being a relatively low impact activity, walking is particularly good for the elderly and research has shown that regular walking in the elderly reduces the chance of fall-related injuries and mental diseases as well. In spite of the documented benefits of regular walking, it is still difficult to walk without the aid of assistive devices for the frail elderly who have lower extremity problems. Assistive walking devices(AWD), such as crutches, canes, hiking-poles, T-Poles and walkers, are often prescribed to the elderly to make their walking be safe and efficient. Many researchers have demonstrated the effects of AWDs such as reducing lower extremity loading, improved dynamic/gait stability, yet, no study has been done for gait pattern when the elderly gait with AWDs. Therefore, the purpose of this study was to examine whether T-Poles, one of the AWDs, change the elderly gait pattern. Eight community-dwelling female elderly participated in this study. Laboratory kinematics during walking with T-Poles(PW) and with out T-Poles(NPW) was assessed. PW showed significant increase in step width, stride length, gait velocity and decrease in swing time. No significances were found in lower body joint angles but meaningful trend and pattern were found. Maybe the reason was due to the participants. Our participants were healthy enough so that the effect of T-Poles was minimum. PW also showed typical gait phases which are no single support phase during a gait cycle. It indicates that walking with T-Poles may guarantee safe and confident walking to the frail elderly.

Network modeling of irrigation system that links irrigation facilities with stream is necessary to establish complicated rural water management system and to manage agricultural water effectively. This study attempted a network modeling for an agricultural water district called "ANGO" located in Anseongcheon watershed by connecting ArcHydro Model developed to control geographical information data in the field of water resources and AWDS(Agricultural Water Demand & Supply Estimation System) developed by KRC (Korea Rural Community & Agriculture Corporation). Network modeling was embodied by build topology between spatial objects of total 70 agricultural irrigation facilities (24 reservoirs, 18 pumping stations, 28 weirs) and stream network using ArcHydro Model. In addition, new menus were added in ArcGIS system for query and visualization of text-based AWDS outputs such as irrigation facilities information, water demand and supply analysis.

현재, 많은 분야에서 데이터 모델링을 지원하는 GIS관련 프로그램으로 ArcObject 컴포넌트를 제안하고 있다. 특히 수자원분야에서 유역과 하천네트워크의 정확하고 효과적인 표현을 위해 ArcHydro Model이 개발되었으며 다양한 분야에서 활용되고 있다. 본 연구에서는 안성군 고삼면의 안고용수구역을 대상으로 ArcHydro Model을 이용하여 관개 네트워크를 구성하기 위해 유역경계, 하천망, 수리시설물의 위치도, 수혜구역도 등의 기본 공간자료들을 구축하고, 이 자료들을 이용하여 수리시설물에 따른 수혜구역을 가시적으로 확인가능하도록 하기 위해 하천의 위상관계를 정립하고 공간자료간의 연계성을 구성하였다. 또한 수리시설물의 농업용수 수요공급량의 정량적인 정보를 획득하기 위하여 ArcHydro Model에 한국농촌공사에서 개발한 AWDS (Agricultural Water Demand and Supply Estimation System. 농촌용수 수요공급량 시스템)와 연계하고, 시설물정보, 수요량분석, 공급량분석을 할 수 있는 메뉴를 구성하여 그 정보를 획득하였다.

During the past decades in South Korea, there have been several projects to reduce water demand and save water for paddy irrigation system by automation. This is called as intensive water management system by telemetering of paddy ponding depth and canal water level and telecontrol of water supply facilities. This study suggests a method of constructing topology-based irrigation network system using GIS tools. For the network modeling, a typical agricultural watershed included reservoirs, irrigation and drainage canals, pumping stations was selected. ArcHydro tools composed of edge, junction, waterbody and watershed were used to construct hydro-network. ArcHydro Model was then designed and the network was successfully built using the HydroID. Visualization using ArcHydro tools could display table property of each object. ArcHydro Model was linked to Agricultural Water Demamd and Supply Estimation System (AWDS) which developed by Korea Rural Community and Agriculture Corporation (KRC) to extract information of the study area. And menu of supply facilities information, demand analysis and supply analysis constructed for information acquisition and visualization of acquired informations.
