  • In this paper, we propose the method to measure tensions of character motions, using LMA (Laban Movement Analysis). Using tension values, we tan take advantage of them as a standard for synchronization of motion and BGM(Back Ground Music). In LMA, a motion is divided into 4 space-time factors which are called Efforts, and each Effort has two bases opposed to each other. We can analyze the motion by justifying which basis is stronger than the other in each Effort of motion. To measure quantitatively tension values, we propose some equations based on kinematics and dynamics. Then we can measure the tension value by the weighted sum of values calculated from those equations. Each weight can be determined by the optimization process which tries to minimize the difference between the calculated tension value and human's decision. The experimental result shows that the in creasing order of the motion tension value is similar to that of the tension score given by human.

  • Hydraulic analysis in a dam that has a single outlet of water can be made through a simple comparison between the total precipitation and the volume of discharged water. In case of tailing dams this estimation could yield an error because several drainage facilities are worked independently as well as simultaneously. In this research, a capability of the drainage system in the tailing dam of the old Sangdong Mine was analysed by the means of GIS technic. As a result of this study, it was expected that in the normal working condition of the whole drainage system, the flooding of water over the dam should not occur in spite of the consecutive precipitation during one hour with an intensity of 80.31 mm/hr, a probable precipitation within 100 years. It was, however, revealed that, if the drainage system did not work completely, the water could flood over the dam when the total precipitation reached 251.1 mm.

  • 서울특별시(이하 서울시)는 기존 상습침수지역과 2010년, 2011년 집중호우로 발생한 침수피해를 바탕으로 34개의 침수취약지역을 선정하고, 이들 지역에 2011년 3월부터 2023년 12월까지 총사업비 1조 5,300억여 원을 투입하여 하수관거 정비, 펌프장 신설 및 증설, 저류조 신설 등 배수능력을 확충하는 사업을 진행해오고 있다. 하지만, 기후변화로 인해 집중형 배수시설의 설계용량을 초과하는 강우의 발생빈도가 증가하고, 극한홍수 발생위험과 기상예측 불확실성이 커짐에 따라, 배수시설의 용량을 증설하는 집중형 우수배제체계 중심의 침수관리만으로는 안전한 침수대응이 어렵게 되었다. 본 연구에서는 서울시 침수대응 다각화를 위해 유역의 자연적, 사회환경적 특성을 대표할 수 있는 52개 지표를 선정하고 서울시를 소규모 유역 단위인 163개의 배수분구로 구분하여 지표별 공간적 분포와 특성 분석을 통해 각 배수분구를 유형화하고, 유형특성에 따른 침수취약성과 잠재적 침수발생 위험성을 분석하여 침수위험성을 평가하였다. 유역의 특성을 대표하는 각종 지표의 서울시 내 공간적 분포를 분석한 결과, 지표별 공간적 분포 특성이 상이했으며, 지표별 최대/최소값의 차이가 수배에서 수백배까지 나타나는 것으로 분석되었다. 특히, 서울시 내외에 산포된 총 40개 기상청관측소의 2010년부터 2019년까지 시간강우자료를 이용하여 강우관련 지표들의 시공간적 분포를 분석한 결과, 연평균강우량, 여름철강우량, 일최대강우량 등에서 지역적으로 최대 수백 mm의 강우량 차이가 발생하는 것으로 나타났다. 유역특성에 따른 서울시 침수위험성을 평가한 결과, 침수발생 및 피해에 불리한 유역의 공간적 취약성이 높은 배수분구로는 봉천1, 송파, 길동, 미아, 상계1 등의 순으로 나타났으며, 침수발생에 대한 잠재적 위험성이 높은 배수분구는 이문, 정릉, 제기1, 장안, 전농 등의 순으로 분석되었다. 침수발생에 대한 잠재적 위험성과 침수피해에 불리한 공간적 취약성이 모두 높아 침수위험성이 큰 배수분구는 상계1, 미아, 장위, 창동1, 동선, 수유2, 방학, 길동, 월계2 등의 순으로 나타났다.

  • To prevent the damage to human health by climate change, vulnerability assessment should be conducted for establishment of adaptation strategies. In this study, vulnerability assessment was conducted to provide information about vulnerable area for making adaptation policy. vulnerability assessment for human health was divided into three categories; extreme heat, ozone, and epidemic disease. To assess vulnerability, suitable indicators were selected by three criteria; sensitivity, adaptive capacity, and exposure, spatial data of indicators were prepared and processed using GIS technique. As a result, high vulnerability to extreme heat was shown in the low land regions of southern part. And vulnerability to harmful ozone was high in the surrounding area of Dae-gu basin and metropolitan area with a number of automobiles. Vulnerability of malaria and tsutsugamushi disease have a region-specific property. They were high in the vicinity of the Dimilitarized zone and south-western plain, respectively. In general, vulnerability of human health was increased in the future time. Vulnerable area was extended from south to central regions and from plain to low mountainous regions. For assessing vulnerability with high accuracy, it is necessary to prepare more related indicators and consider weight of indicators and use climate prediction data based on the newly released scenario when assessing vulnerability.

  • Existing traffic safety studies have focused on identifying the relationship among roadway crashes, highway design and incremental weather condition such as rainy/ice weather. However, it is hard to find researches that studied the effect of sun glare on traffic safety although there are abundant evidences demonstrating that fatal traffic crashes are attributed to the sun glare. Affecting drivers'vision particularly during the morning or the evening time when the sun positions close to the horizon, sun glare directly deteriorate drivers'judgmental capability. In this paper, we numerically analyze the effect of sun glare on the drivers'vision in time and space domains. Applied to the roadways around St Louis area in the United States, the GIS based simulation analysis identifies the time of day in a year and the segments of highways that are potentially influenced by the sun glare. This study evidentially confirms the fact that roadway bounded for West and East directions have longer time influenced by sun glare particularly during Spring and Fall season than other roadways. The computational result provides risky time periods of day at intersections or pedestrian crossings where the sun glare potentially endangers traffic safety, which be utilized to reduce the crashes due to the sun glare.

  • In school science class, actual geological field trips tend to be restricted due to a number of problems including travel distance, cost, safety, and so on. Therefore, alternative way should be sought to provide students with the benefits of actual field trip. The purpose of this study is to develop web-based virtual field trip (VFT) about Jeju island in Korea by using flash panorama, and to explore a variety of ways to utilize the VFT. The characteristics of Jeju VFT are as follows: it provides virtual space for secondary school students to learn about volcanic topography and geology; students can access contents in a non-sequential order by virtue of web-based system, and students can control learning pace according to their ability; it is possible to investigate the same field site repeatedly, not limited by time and space; it presents differentiated worksheets for different school grade; it provides diverse complementary web contents, e. g., closeup features, thin sections, inquiry questions, and explanations of outcrops. We proposed several ways with instructional models to utilize Jeju VFT in science class and extra-school curricular as well.

  • Multi-purpose dams in Korea play a very important role in water management such as supplying water for living, industrial water, and discharging instream flow requirement to maintain the functions of river. However, the vulnerability of dam water supply has been increased due to extreme weather events that are possible linked to climate change. This study attempts to project the future dam inflow of six multi-purpose dams by using dynamically downscaled climate change scenarios with high resolution. It is found that the high flows are remarkably increased under global warming, regardless of basins and climate models. In contrast, the low flows for Soyangang dam, Chungju dam, and Andong dam that dam inflow are originated from Taebaek mountains are significantly decreased. On the other hand, while the low flow of Hapcheon dam is shown to increase, those of Daecheong and Sumjingang dams have little changes. But, the low flows for future period have wide ranges and the minimum value of low flows are decreased for all dams except for Hapcheon dam. Therefore, it is necessary to establish new water management policy that can respond to extreme water shortages considering climate change.

  • The purposes of this study are to suggest flood vulnerability assessment method on climate change with evaluation of this method over the 5 river basins and to present the uncertainty range of assessment using multi-model ensemble scenarios. In this study, the data related to past historical flood events were collected and flood vulnerability index was calculated. The vulnerability assessment were also performed under current climate system. For future climate change scenario, the 39 climate scenarios are obtained from 3 different emission scenarios and 13 GCMs provided by IPCC DDC and 312 hydrology scenarios from 3 hydrological models and 2~3 potential evapotranspiration computation methods for the climate scenarios. Finally, the spatial and temporal changes of flood vulnerability and the range of uncertainty were performed for future S1 (2010~2039), S2 (2040~2069), S3 (2070~2099) period compared to reference S0 (1971~2000) period. The results of this study shows that vulnerable region's were Han and Sumjin, Youngsan river basins under current climate system. Considering the climate scenarios, variability in Nakdong, Gum and Han river basins are large, but Sumjin river basin had little variability due to low basic-stream ability to adaptation.

  • The purpose of this study was to assess the vulnerability of forest ecosystem to climate change in South Korea using socio-environmental indicators and the results of two vegetation models named as Hydrological and Thermal Analogy Group(HyTAG), and MAPSS-Century 1(MC1). The changing frequency and direction of biome types estimated by HyTAG model was used for quantifying sensitivity and adaptive capacity of forest distribution. Similarly, the variation and changing tendency of net primary production and soil carbon storage estimated by MC1 model was used for quantifying sensitivity and adaptive capacity of forest function. As socio-environmental indicators, many statistical data such as financial autonomy rate and the number of forestry officer was prepared. All indicators were standardized, and then calculated using the vulnerability assessment equation. The period of vulnerability assessment was divided into the past(1971-2000) and the future(2021-2050). To understand what policy has a priority to climate change, distribution maps of each indicators was depicted and the vulnerability results were compared among administrative districts. Evident differences could be found in entire study area. These differences were mostly derived from regionalspecific adaptive capacity. The result and methodology of this study would be helpful for the development of decision-making supporting system and policy making in forest management with respect to climate change.
