  • City parks play an important role in reducing the air pollution and mitigating the city heat island effect caused by global warming. However, from July 2020, restricted parks over 20-year will be partially lifted due to sunset regulation on parks. As a result, the government and local governments have been making efforts to revitalize parks, such as creating ecological parks and securing park sites. However, building winds generated by high-rise buildings constructed around ecological parks in the city may cause discomfort to pedestrians and threaten the ecosystems of plants and animal that live in ecological parks. There are no clearly proposed as standards for wind environment assessment in Korea, but also it has been rarely studied on pedestrian wind environment. In this study, wind environment studies have been reviewed to find the important parameters related to wind environment assessment. Further, wind climate analysis using wind data obtained by Seoul meterological station was performed to examine the possibility of applicability of the wind environment assessment on the city ecological parks.

  • We observed tidal currents throughout all four seasons in 2007 at a single station, located 1.6km off Haeundae Beach and compared these current data with wind data. The direction of seasonal wind represented a similarity between the winds at sea and on land but the speed of wind at sea was almost three times stronger than the wind on land. In addition, the wind at sea turned out to considerably affect on tidal currents, particularly from late summer to autumn. On the other hand, the thickness of Ekman Layer, indicating a limitation of wind influence, was estimated to be 31.8 m on average, suggesting that the entire water column is under the influence of wind. Therefore, we are required to consider the wind stress into the analysis of tidal currents for the prevention of the loss of sand from Haeundae Beach.

  • Sea level rise and increase of the typhoon/hurricane intensity due to global warming have threaten coastal areas for residential and industrial and have been widely studied. In this study we showed our recent efforts on sea wind which is one of critical factors for safe maritime traffic and prediction for storm surges and waves. Currently, most of numerical weather models in korea do not have sufficient spatial and temporal resolutions, therefore we set up a find grid(about 9km) sea wind prediction system that predicts every 12 hours for three day using Weather Research and Forecasting(WRF). This system covers adjacent seas around korean peninsula Comparisons of two observed data, Ieodo Ocean Research station(IORS) and Yellow Sea Buoy(YSB), showed reasonable agreements and by data assimilation we will improve better accurate sea winds in near future.

  • Modern and contemporary humanities and social sciences supported the freedom and abundance of people. Today, however, freedom and abundance do not support human dignity, and are not sustainable. Therefore, we must reflect again on the direction of today's life and civilization. As part of this project, this essay analyzes the modern and contemporary humanities and social sciences and examines the meaning of Korean traditional thoughts. The lines presented to us by Korean traditional thought can be summed up 'the Three Elements of the Universe(Heaven, Earth and Man)' and 'Perfect Harmony between the Soul and the Body' and 'true humanitarianism.' These lines can be a starting point to overcome the problems posed by the lines of freedom and abundance in two contexts : First, while the lines of freedom and abundance today were biased toward the elements of the Earth or the Body, the traditional Korean thoughts have been both elements of the Heaven and the Soul since the beginning, which can therefore serve as a true humanitarian. Second, the true humanitarian line is as much sustainable as it criticizes the uncontrolled freedom and abundance, and seeks the right moderation to become a man of dignity.

  • 패션 트렌드에 있어서 1920년대 이후 복고풍(Retro)이라는 이름 하에 현재에 이르기까지 거의 모든 시대가 주요 배경으로 등장하였다. 때로는 시대에 뒤떨어진 것으로 여겨졌던 옷들을 맞추어 입은 느낌이 들기도 하며 때로는 어느 시대, 어느 스타일인지 구분할 수 없는 옷들이 '복고풍' 이라고 넘어 가는 것이 대부분이었다. 이러한 경향은 정장류이든, 캐주얼류이든, 그리고 성별과 연령에 관계 없이 특히 21세기 들어 모두 복고풍의 디자인들이 많다.

  • 태풍의 경우, 주요 자연재해 중의 하나로 태풍의 상황을 정확하게 파악하는 것은 기상예측의 정도를 높이고, 재해를 방지하는데 중요한 역할을 할 수 있다. 일반적으로 태풍의 동향을 감시하는데 있어, MTSAT 등의 기상위성이 주로 활용되고 있다. 근년 인공위성의 원격탐사를 이용하여 광범위의 해양에 대한 해상풍과 파랑의 관측이 가능하게 되었다. 본 연구에서는, 2000년 QuickSCAT위성에 의한 해상풍의 월변동 특성을 조사하고, 7월에 한반도에 영향을 준 태풍 카이탁내의 해상풍을 검토하였다. 추가로 2005 년 8월 30일의 태풍 탈림에 대해서 ENVISAT ASAR Scan SAR에 의한 해상풍 추출을 시도하였다. QuickSCAT 에 의한 풍향을 이용한 방법과 SAR 자체의 패턴을 이용한 방법이 비교되었다.

  • The probabilistic characteristics of wind loads have been analyzed using statistical data on wind speeds, pressure coefficient, exposure coefficient, and gust factor. The wind speed data collected at 25 nationwide weather stations have been modified to be consistent in measuring height, exposure condition as well as averaging time. Having performed Monte Carlo simulation for various heights and site conditions, the statistical models of wind loads were determined, in which Type-I extreme value distribution has been applied. The models also incorporate a reduction factor of 0.85 to account for the reduced probability that the maximum wind speed will occur in a direction most unfavorable to the response of structure.

  • In this study, field measurements on KTX, Nuriro and TTX train have been conducted at Kyeongbu and Honam line to predict the wind gust under train at the speed-up of major conventional railway lines using Kiel-probe array and multi-channel pressure scanning system. The results show that the average wind velocity during train passage normalized by train speed is independent to train speed, thus the wind gust for a given train type at the speed-up condition could be predicted. The relationship between the shape of underbody and the characteristics of the underbody wind gust has been discussed.

  • In game characters, the direction of character design varies depending on the expression or production method. It is necessary to perform game character personality design by reflecting the importance. This study derives the importance of the game character personality model using AHP for the efficient decision and presents game character personality design check tool. In design elements, the importance of external appearance was the highest in all of style. In personality factors, action in 3D realism, external appearance in 3D animation, and speech in 2D animation were the most important.
