방수로는 홍수 피해 경감을 사용되는 구조적 대책으로 최근 국내에서 널리 계획되고 있다. 이러한 방수로는 보통 횡월류위어 등으로 대표되는 유입부 구조물을 통하여 하천 본류와 연결되지만, 평상시에도 본류의 유량을 일부 분담하는 형태로 설계되는 젖은 하도(wet channel) 형태의 방수로는 별도의 유입부 구조물을 설치하지 않고 바로 본류에 연결되는 것이 일반적이다. 유입부 구조물을 통해 연결되는 방수로의 특성은 유입부 구조물의 수리학적인 특성에 의해서 많이 좌우된다. 이에 반해 젖은 하도 형태로 본류에서 바로 분기되는 방수로는 그 특성이 방수로의 폭(W), 방수로 분류각$(\theta)$등에 의해서 많이 좌우되며, 만약 설계된 방수로의 횡단면 형상이 사다리꼴 또는 직사각형 단면을 따른다면 이러한 흐름은 "제한 영마루고 횡월류위어 흐름(restricted zero-height side weir flow)"으로 분류할 수 있다. 이러한 조건에서의 흐름은 일반적인 횡월류위어 흐름과 많이 다른 것으로 알려져 있다. 본 연구에서는 이러한 방수로 폭 및 분류각을 변화시켜 방수로 분류 조건을 다양하게 구현하여 실험을 수행하였으며, 특히 분류각 변화에 따른 유량계수의 변화를 분석, 검토하였다. 또한 측정된 방류량을 기준으로 산정된 유량계수를 기존 연구자들이 제시한 영마루고(zero-height) 횡월류위어 유량계수 산정식에 의해 산정된 결과와 비교하여 분석하였다. 분석결과 분류각이 90도인 경우 본류 프루드수의 증가에 따라 유량계수가 점차 감소하였으나, 분류각이 90도 보다 작은 경우에는 본류 프루드수가 증가함에 따라 유량계수가 점차 증가하는 것으로 나타났다. 이러한 한계를 만족시킬 입체 영상) 입체영상은 영화에서 시작되었으나, 20c후반기에 들어서면서 애니메이션 분야와 모바일, 광고 패널, 텔레비전등의 매체를 이용한 입체 영상의 개발로 인하여 특정 분야에 한정 시킬 수 없으므로 영상으로 칭한다. 입체 영상은 21c에 들어서면서 영상매체의 한 분야로 급부상하고 있다. 1900년 무렵부터 연구된 입체영화(3-Dimensional motion Picture)는 In여 년이 지난 지금 대중화를 눈앞에 두고 있다. 국내에서는 놀이 동산이나 박물관등에서 흔히 볼 수 있다. 하지만 앞으로는 HDW등의 대중화로 화질의 발전을 이룬 텔레비전 분야 등에서 실용화 될 전망이다. 국제적인 흐름과 함께 국내에서도 입체 영화에 대한 연구가 활성화 되어 영상산업의 한 주류로서 대두되고 있다. 이러한 상황에서 입체영상에 대한 이해와 콘텐츠(Contents)의 개발은 기술적인 진보에 발맞추어 준비되어야 한다. 본 논문은 이러한 기술적인 계보에 발맞춘 영상 콘텐츠 개발에 박차를 가하고자 앞으로의 발전분야에 대한 기술적인 면과 기법적인 면을 제시하여 기술만 앞서고 내용은 수입하는 수입국이기 보다는 미리 준비하여 비전문가나 타국의 기술에 선점 당하지 않는 분야로 성장할 수 있는 진보적인 영상 인들의 관심과 지속적인 연구를 독려하고자 한다.시민의 휴식 및 여가선용 공간으로 활용하기 위한 사업의 기초자료로 활용되며 이미 설계검토가 시작되었다. 본 연구결과는 유수지 및 저수지의 환경개선 사업의 선두적인 성공사례로 국내 타 지역의 유사한 사업에 있어 벤치마킹을 할 수 있는 훌륭한 사례가 될 것이다.요 생산이 증가하자 군신의 변별(辨別)과 사치를 이유로 강력하게 규제하여 백

OGC(Open GIS Consortium, Inc.)에서 2000년에 XML의 지리정보 처리를 위한 GML 1.0이 제안된 이후 최근 GML 3.0이 발표되기까지 국제적으로는 다양한 GIS 응용분야에서 GML을 현실 문제에 이용하고자 하는 시도가 이루어지고 있다. 현재 우리나라에서도 국가 GIS(NGIS)에서 GML을 도입하여 국내 표준안으로 추진하고자 다양한 기반연구가 진행되고 있다. 본 연구는 중요한 GIS 응용중의 하나인 지질자원 정보 분야에서 GML을 활용하기 위한 기반연구로서 우리나라의 표준 지질도(또는 수치지질정보)와 기타 지질자원 정보 인프라 구축에 적용될 수 있는 다양한 지구과학자료를 대상으로 하였다. 따라서 본 연구에서는 지질자원 분야에서의 GML 응용을 위한 기반 데이터 모델과 이를 처리하기 위한 아키텍처를 UML 기법으로 설명하고, 이를 바탕으로 시험 구현된 운용환경에서 실제 대상 지역을 선정하여, 연구지역에 대한 지질자원 정보의 GML 적용 사례를 제시하고자 한다. 이를 위한 연구 내용으로는 수치 지질도를 XML-GML의 기본 스키마구조에 따라 엔코딩한 뒤, 주제정보의 표현을 위한 XSLT, SVG 파일 변환 처리 등을 수행하였다. 결론적으로 본 연구는 지질자원 분야의 정보화 인프라 구축을 목적으로 하는 기초 시험연구로 수행되었는 바, 우리나라에서는 2001년 이후 GIS 수치 주제도로서 수치 지질도의 보급이 활성화되면서, 이 정보를 제작/공급하는 기관이나 업무에 사용하는 기관 등에서 GML 기반으로 데이터를 제작하거나 운용이 가능할 것으로 생각된다. 또한, 다른 분야에서 GIS 주제정보를 다루는 경우에도 GML을 주제정보와 연계하여 현실 문제에 적용이 가능한 창조 모델로 이용될 수 있을 것으로 생각된다.}94,\;29.4{\pm}30.3,\;45.1{\pm}44$로 Mel 10군과 Mel 30군이 유의적인 감소를 보였으나(p<0.05) 이들 두 군 간의 차이는 나타나지 않았다. 이상의 결과로, 랫트에서 복강수술 후 melatonin 10mg/kg투여가 복강 내 유착 방지에 효과적이라고 생각된다.-1}{\cdot}yr^{-1}$로서 두 생태계에 축적되었다.여한 3,5,7군에서 PUFA 함량이 증가한 반면, SFA 함량은 감소하여 P/S 비율, n-3P/n-6P 비율은 증가하는 경향이었으며 이는 간장의 인지질, 콜레스테롤 에스테르, 총 지질의 지방산조성에서도 같은 경향을 볼 수 있었다.X>$(C_{18:2})$와 n-3계 linolenic acid$(C_{18:3})$가 대부분을 차지하였다. 야생 돌복숭아 과육 중의 지방산 조성은 포화지방산이 16.74%, 단불포화지방산 17.51% 및 다불포화지방산이 65.73%의 함유 비율을 보였는데, 이 중 다불포화지방산인 n-6계 linoleic acid$(C_{18:2})$와 n-3계 linolenic acid$(C_{18:3})$가 지질 구성 총 지방산의 대부분을 차지하는 함유 비율을 나타내었다.했다. 하강하는 약 4일간의 기상변화가 자발성 기흉 발생에 영향을 미친다고 추론할 수 있었다. 향후 본 연구에서 추론된 기상변화와 기흉 발생과의 인과관계를 확인하고 좀 더 구체화하기 위한 연구가 필요할 것이다.게 이루어질 수 있을 것으로 기대된다.는 초과수익률이 상승하지만, 이후로는 감소하므로, 반전거래전략을 활용하는 경우 주식투자기간은 24개월이하의 중단기가 적합함을 발견하였다. 이상의 행태적 측면과 투자성과측면의 실

In the near future, we are expected to live in a Mixed Reality environment where reality and virtuality coexist as today we live using the Internet and smartphones in our daily lives. The relevant content based on the idea of Mixed Reality crystallizing is currently expanding, and it is time for research on it. This study examines the current situation and the development direction of mixed reality contents. Typical mixed reality contents can be classify by wearability. We analyzed HoloLens, a mixed reality wearable device that is worn on a head, which is a example of wearable device. As an example of unwearable device, we also analyzed the Room2Room which is a communication system that combines video with augmented reality-based telepresence avatar. Mixed Reality content will develop in the direction of implementing expanded use of information and more natural realism through the interactive combination of Reality, Virtual Reality, and Augmented Reality. As head-mounted wearable technology develops, Mixed Reality content is expected to become popular by increasing the number of Mixed Reality device users if convenience and price competitiveness are secured. The way of unifying Mixed Reality wearable devices must be established in order to increase convenience, and the environment based on Mixed Reality will be created through diversifying leisure activity content. Telepresence Avatar is expected to develop into Mobile Hologram Avar as Mixed Reality content accessible anywhere and at anytime beyond space limits. Another potential for development of Telepresence Avatar is the combination of Avatar moving on user's thought, Augmented Human technology and Mixed Reality.

Amid public's growing interest on garden and more leisure time of modern life-style, there is an effort by the government to utilize forest as public garden. In order to utilize forests as pubic garden, a new concept of "Forest Garden" should be defined and introduced first. Furthermore, introducing a new concept requires academically analyzing values of a new concept before a new concept is widely used. Thus, we aimed to clarify the concept of forest garden by conducting Delphi technique research and factor-analysis of survey results. More specifically, delphi technique research was conducted to extract composition elements and explanation elements of forest garden. Factor analysis was conducted on the top 25 elements and 5 values were extracted as a result. They are form, scenery, ecology, history/cuture and usefulness which are essential values required of forest garden. Forest garden should have all of 5 values and be capable of function as both forest and garden which would also need continuous maintenance. We believe this study is the first one to establish definition of forest garden and more specific and realistic definitions need to be built through continuous research, 000 experiment and on-site evaluation. We also believe that this study will serve as foundation for further efforts in building forest garden in various space and in defining proper concept of forest garden.

Traditionally, travel demand forecasts have been conducted based on the data collected by a survey of individual travel behavior, and their limitations such as the accuracy of travel demand forecasts have been also raised. In recent, advancements in information and communication technologies are enabling new datasets in travel demand forecasting research. Such datasets include data from global positioning system (GPS) devices, data from mobile phone signalling, and data from call detail record (CDR), and they are used for reducing the errors in travel demand forecasts. Based on these background, the objective of this study is to assess the feasibility of CDR as a base data for travel demand forecasts. To perform this objective, CDR data collected for Daegu Metropolitan area for four days in April including weekdays and weekend days, 2017, were used. Based on these data, we analyzed the correlation between CDR and travel demand by travel survey data. The result showed that there exists the correlation and the correlation tends to be higher in discretionary trips such as non-home based business, non-home based shopping, and non-home based other trips.

The study was to improve the right to the enjoyment of culture of persons with visual impairment by increasing the accessibility to art exhibitions and exploring assistive measures through needs assessment survey of persons with visual impairment on arts exhibition. We used total 83 responses collected through an online survey. The result are as follows. First, watching movies at a teather was the most frequent leisure activity among persons with visual impairment, while respondents reported attending art exhibitions as the least frequent activity. Yet, 71.1% included attending art exhibitions as one of their top 5 culture and leisure activities. Most of the respondents reported the purpose of attending art exhibitions as fun. However, a primarily visual atmosphere prevented them from visiting the exhibition. Second, persons with visual impairment preferred approaching the art to have a closer look. More than about 50% of the respondents used their residual vision. Most of the respondents reported to use more than two senses when appreciating the exhibits. Moreover, respondents reported that devices/services for multi-sensory experiences would be helpful to appreciate the art. The findings imply that the consideration of the characteristics and needs of persons with visual impairment is required for establishing the environment of art exhibitions. This could further contribute to the improvement of the right to the enjoyment of leisure and culture of persons with visual impairment and lead to the realization of social integration.

The current study aimed to examine how the caregivers and speech language pathologists (SLPs) would perceive the important communication contexts for 3~6 year-old children in the script-based intervention. Analytic Hierarchy Process analyses were conducted for the obtained survey data from SLPs and caregivers. Results showed that caregivers perceived 'educational and social life' and SLPs perceived 'family life' as the most important contexts from among three high-level contexts. Within each high-level context, 'meal time' in 'family life', 'playing with friends' in 'educational and social life', and 'playground' in 'culture and leisure life' were the most important communication contexts. Also, from among 35 global priority rank, caregivers perceived 'playing with friends' while SLPs perceived 'meal time' as the most important contexts, and 'family life' was high priority among first five ranked context both in caregivers and SLPs. In caregiver groups by children's age, 3 year- and 6 year-caregiver groups perceived 'family life' and 4 year- and 5 year-caregiver groups perceived 'educational and social life' as the most important contexts. There were also slight differences between caregiver groups by age in the rank order of communication contexts across the high level contexts. These results suggest that SLPs may need to consider not only child's age and developmental level but also caregiver's demands in selecting the appropriate communication contexts when delivering the script-based speech language intervention.
