  • In this paper, our proposed system uses the regional Gabor wavelet and Neural Network to implement face recognition similar to human face recognition system, because the Gator wavelet expresses visual recognition system of human mathematically and the regional Neural Network is robust to white noise and partial illumination. This system consists of two stages of building database and recognizing face. One is composed by using the supervised learning of Neural Network. At this time, the Neural Network is applied to the upper and the lower part of face images respectively. The Backpropagation algorithm is used to learn Neural Network. Another consists of calibration of slope of face image, measurement of illumination variant using deviation with average face image and similarity comparison using Euclidean distance measure.

  • International arbitration as a dispute resolution mechanism in Asia is growing in popularity. Singapore has long been acknowledged as a regional arbitration center but Korea is now facing an increased demand as an arbitration center as well. As Singapore competes with Hong Kong and other international arbitration centers, and as Korea tries to become an alternative to Singapore, both Singapore and Korea have updated their arbitral laws and arbitration rules to reflect the current international arbitration trends. This paper examines the recent changes in the arbitration laws of Singapore and Korea, with an emphasis on recent changes in Korean arbitration laws that are designed to increase Korea's popularity as a regional arbitration center. Though Korea's reputation as an arbitration center is increasing, it is still not viewed as a major arbitration service provider. It is against this backdrop that Korea's international arbitration laws and rules will be viewed, with suggested changes to increase Korea's reputation as not only a regional hub but a center of international arbitration.

  • Runoff, NPS pollution load and flow-weighted mean concentration (FWMC) occurred by snowmelt and rainfall runoff were compared by a variance analysis. Snowmelt runoff ranged between 1,449 and $19,921m^3$. The peak snowmelt runoff was similar to the runoff that occurred by about 40mm/day rainfall. And average snowmelt runoff was not significantly different from the runoff that occurred by 25.5 mm/day rainfall. Average values of SS loads and FWMCs were 5,438 kg/day and 954.9 mg/L, respectively. SS loads and FWMCs were in the similar range with those that occurred by 39.0 mm/day and 53.0 mm/day rainfall, respectively. Daily SS and COD loads and FWMCs occurred by snowmelt and rainfall were analyzed not to be significantly different. Overall assessment led that the NPS pollution loads by snowmelt runoff had a similar characteristics with the loads by about 40 mm/day rainfall runoff. It was recommended that the agricultural fields in snowy region needs to managed not only for rainfall runoff but also snowmelt runoff for an effective water quality management.

  • Purpose: The purpose of this study was to analyze the effectiveness of regional trauma center's management. Methods: Data collected between January 2013 and December 2015 from a regional trauma center registry was retrospectively reviewed. The patients who had injury severity score (ISS) greater than 15 and over the age of 18 were included. We compared annual general characteristics, the injury mechanism, the pathway of transportation, the injury severity score, the length of stay in emergency department (ED) and hospital, the in-hospital mortality. Results: The annual numbers of enrolled patients were 337, 334 and 278, respectively. No significant differences were found in the annual patient's median ages, injury mechanism, ISS and in-hospital mortality. The annual proportions of coming from other hospital and the median length of stay in hospital were increased after establishment of regional trauma center. The annual median lengths of stay in ED were decreased remarkably. Conclusion: Through the establishment of regional trauma center, the length of stay in ED can be reduced but not in-hospital mortality. More multidisciplinary cooperation and well-organized study is needed to reduce mortality of major trauma patients and maximize effect of regional trauma center.

  • Surface winds over the ocean influence not only the climate change through air-sea interactions but the coastal erosion through the changes in wave height and direction. Thus, demands on a reliable projection of future changes in surface winds have been increasing in various fields. For the future projections, climate models have been widely used and, as a priori, their simulations of surface wind are required to be evaluated. In this study, we evaluate the climatological mean surface winds over the Korean Waters simulated by five regional climate models participating in Coordinated Regional Climate Downscaling Experiment (CORDEX) for East Asia (EA), an international regional climate model inter-comparison project. Compared with the ERA-interim reanalysis data, the CORDEX-EA models, except for HadGEM3-RA, produce stronger wind both in summer and winter. The HadGEM3-RA underestimates the wind speed and inadequately simulate the spatial distribution especially in summer. This summer wind error appears to be coincident with mean sea-level pressure in the North Pacific. For wind direction, all of the CORDEX-EA models simulate the well-known seasonal reversal of surface wind similar to the ERA-interim. Our results suggest that especially in summer, large-scale atmospheric circulation, downscaled by regional models with spectral nudging, significantly affect the regional surface wind on its pattern and strength.

  • Japan's manufacturing is mostly dependent on the automotive industry in Toyota-Kariya cities. However, the nearby city of Hamamatsu is the home of a start-up ecosystem known as Japan's Silicon Valley. How is it possible to evaluate the innovative potential of each regional industry? What kind of guidelines exist for continuing R&D investment when companies' net incomes are negative in the face of the 'Valley-of-Death' or financial crisis? Is it possible to measure the regional resilience ability in the context of the financial crisis? Entrepreneurial innovation is defined as a real-option portfolio consisting of investment decision to commercialize R&D findings. The subcontractor system implies a vertical and tight industrial group. However, a start-up ecosystem means a platform for horizontal and flexible partnership. In this research, the data include the financial indices of each of 18 public companies in both regions between FY2009 and FY2017. The objective of this paper is to clarify the call option or resilience function of equity for R&D investment in the context of the financial crisis in both regions by using Bayesian MCMC analysis.

  • 충청지역의 다양한 유적의 소토(燒土)에서 구한 34점의 고고지자기 측정데이터를 통해 충청지역의 고고지자기 변동 양상을 살펴보고, 더 나아가 국내에서의 지자기의 지역적인 차이에 대해 검토해 보았다. 충청지역의 고고지자기 측정데이터는 거리상으로 차이가 있는 일본의 고고지자기 변동과의 비교에서 보면, 전체적인 변동 모습은 비슷하나 A.D. 300년경에서는 편각이 동쪽으로 10도 이상 치우치는 현저한 차이를 보이고, 그 이외 시기에서는 복각이 다소 깊어지고 편각이 서쪽으로 약간씩 치우치는 지자기의 지역적인 차이가 확인되었다. 이러한 양상은 우리나라 전체의 고고지자기 변동 양상과 큰 차이가 없으며, 충청지역 데이터와의 직접 비교에서도 국내에서는 서력기원전시기와 기원후 시기 모두 뚜렷한 지자기의 지역차는 확인되지 않았다. 앞으로 더 많은 고고지자기 측정 데이터가 증가하고 다양한 시기의 데이터가 채워지면 더욱 명확해 지겠지만, 충청지역 유적의 고고지자기 측정결과를 통해 볼 때, 지자기의 지역적인 차이에 의해 발생하는 고고지자기 측정연대의 오차와 같은 문제점은 우리나라 내에서는 크게 걱정하지 않아도 될 듯하다. 게다가 시료의 채취와 측정에서 신뢰가 가능한 측정데이터를 구하기 위하여 많은 노력들을 하고 있기 때문에, 고고지자기 측정결과에서 추정연대의 오차문제 뿐만 아니라 데이터의 신뢰도의 측면에서도 문제가 없을 것이라 생각된다.
