| 1 | Incorporation of Parameter Uncertainty into Spatial Interpolation Using Bayesian Trans-Gaussian Kriging显示文摘Quantitative precipitation estimation(QPE) plays an important role in meteorological and hydrological applications.Ground-based telemetered rain gauges are widely used to collect precipitation measurements. Spatial interpolation methods are commonly employed to estimate precipitation fields covering non-observed locations. Kriging is a simple and popular geostatistical interpolation method, but it has two known problems: uncertainty underestimation and violation of assumptions.This paper tackles these problems and seeks an optimal spatial interpolation for QPE in order to enhance spatial interpolation through appropriately assessing prediction uncertainty and fulfilling the required assumptions. To this end, several methods are tested: transformation, detrending, multiple spatial correlation functions, and Bayesian kriging. In particular, we focus on a short-term and time-specific rather than a long-term and event-specific analysis. This paper analyzes a stratiform rain event with an embedded convection linked to the passing monsoon front on the 23 August 2012. Data from a total of 100 automatic weather stations are used, and the rainfall intensities are calculated from the difference of 15 minute accumulated rainfall observed every 1 minute. The one-hour average rainfall intensity is then calculated to minimize the measurement random error. Cross-validation is carried out for evaluating the interpolation methods at regional and local levels. As a result,transformation is found to play an important role in improving spatial interpolation and uncertainty assessment, and Bayesian methods generally outperform traditional ones in terms of the criteria. | Joon Jin SONG Soohyun KWON Gyu Won LEE | 2015 | Advances in Atmospheric Sciences2015，32，3： | 6 |
| 2 | Classification of Precipitation Types Using Fall Velocity–Diameter Relationships from 2D-Video Distrometer Measurements显示文摘Fall velocity–diameter relationships for four different snowflake types(dendrite,plate,needle,and graupel) were investigated in northeastern South Korea,and a new algorithm for classifying hydrometeors is proposed for distrometric measurements based on the new relationships.Falling ice crystals(approximately 40 000 particles) were measured with a two-dimensional video disdrometer(2DVD) during a winter experiment from 15 January to 9 April 2010.The fall velocity–diameter relationships were derived for the four types of snowflakes based on manual classification by experts using snow photos and 2DVD measurements:the coefficients(exponents) for different snowflake types were 0.82(0.24) for dendrite,0.74(0.35) for plate,1.03(0.71) for needle,and 1.30(0.94) for graupel,respectively.These new relationships established in the present study(PS) were compared with those from two previous studies.Hydrometeor types were classified with the derived fall velocity–diameter relationships,and the classification algorithm was evaluated using 3 × 3 contingency tables for one rain–snow transition event and three snowfall events.The algorithm showed good performance for the transition event:the critical success indices(CSIs) were 0.89,0.61 and 0.71 for snow,wet-snow and rain,respectively.For snow events,the algorithm performance for dendrite and plate(CSIs = 1.0 and 1.0,respectively) was better than for needle and graupel(CSIs = 0.67 and 0.50,respectively). | Jeong-Eun LEE Sung-Hwa JUNG Hong-Mok PARK Soohyun KWON Pay-Liam LIN Gyu Won LEE | 2015 | Advances in Atmospheric Sciences2015，32，9： | 5 |
| 3 | Microfluidic three-dimensional cell culture of stem cells for high-throughput analysis显示文摘Although the recent advances in stem cell engineering have gained a great deal of attention due to their high potential in clinical research,the applicability of stem cells for preclinical screening in the drug discovery process is still challenging due to difficulties in controlling the stem cell microenvironment and the limited availability of high-throughput systems.Recently,researchers have been actively developing and evaluating three-dimensional(3D)cell culture-based platforms using microfluidic technologies,such as organ-on-a-chip and organoid-on-a-chip platforms,and they have achieved promising breakthroughs in stem cell engineering.In this review,we start with a comprehensive discussion on the importance of microfluidic 3D cell culture techniques in stem cell research and their technical strategies in the field of drug discovery.In a subsequent section,we discuss microfluidic 3D cell culture techniques for high-throughput analysis for use in stem cell research.In addition,some potential and practical applications of organ-on-a-chip or organoid-on-a-chip platforms using stem cells as drug screening and disease models are highlighted. | Jeong Ah Kim Soohyun Hong Won Jong Rhee | 2019 | World Journal of Stem Cells2019，11，10： | 3 |

| 5 | Room temperature hydrogen sensing performances of multiple networked Ga N nanowire sensors codecorated with Au and Pt nanoparticles显示文摘The sensing performances of multiple networked Ga N nanowire(NW) sensor codecorated with Au and Pt nanoparticles were examined. The pristine Ga N nanowires show responses of approximately 108%-173% to 0.05%-0.25% H2 at room temperature. On the other hand, the Ga N nanowires decorated with Au and those decorated with Pt lead to 1.1-1.3 and 1.2-1.6 times,respectively, stronger responses to 0.05%-0.25% H2. In contrast, the Au Pt-codecorated Ga N nanowires show 1.3-2.0 times stronger responses to 0.05%-0.25% H2. In other words, the Ga N nanorods codecorated with Au and Pt nanoparticles show much stronger response to H2 gas than the Au or Pt monometal-decorated counterpart. The underlying mechanism for the enhanced response of the Au Pt-codecorated Ga N nanowire was discussed. | PARK Sunghoon KIM Soohyun PARK Suyoung LEE Sangmin LEE Chongmu | 2015 | Journal of Central South University2015，22，5： | 2 |

| 19 | Rapid Establishment of Tracheal Stenosis in Pigs Using Endotracheal Tube Cuff Overpressure and Electrocautery显示文摘To apply a new airway treatment to humans, preclinical studies in an appropriate animalmodel is needed. Canine, porcine and leporine tracheas have been employed as animal airwaystenosis models using various methods such as chemical caustic agents, laser, and electrocautery.However, existing models take a long time to develop (3- 8 weeks) and the mechanism of stenosisis different from that in humans. The aim of the present study was to establish a new and fasttracheal stenosis model in pigs using a combination of cuff overpressure intubation (COI) andelectrocautery. Fourteen pigs were divided into three groups: tracheal cautery (TC) group (n=3),COI group (n=3), and COI-TC combination group (n=8). Cuff overpressure (200/400/500 mmHg)was applied using a 9-mm endotracheal tube. Tracheal cautery (40/60 watts) was performed usinga rigid bronchoscopic electrocoagulator. After intervention, the pigs were observed for 3 weeks andbronchoscopy was performed every 7 days. When the cross-sectional area decreased by > 50%, itwas confirmed that tracheal stenosis was established. The time for tracheal stenosis was 14 days inthe TC group and 7 days in the COI-TC combination group. In the COI group, no stenosis occurred.In the COI-TC group, electrocautery (40 watts) immediately after intubation for>1 h with a cufpressure of 200 mmHg or more resulted in suficient tracheal stenosis within 7 days. Moreover, thedegree of tracheal stenosis increased in proportion to the cuff pressure and tracheal intubation time.The combined use of cuf overpressure and electrocautery helped to establish tracheal stenosis inpigs rapidly. | Jin Hyoung Kim Jong Joon Ahn Yangin Jegal Soohyun Bae Soon Eun Park Moon Sik Jung Ju Ik Park Hee Jeong Cha Yongjik Lee Taehoon Lee | 2021 | Current Medical Science2021，41，2： | 0 |
| 20 | 阶段约束下Gauss配点离散化平行车位自动泊车轨迹规划显示文摘针对平行车位自动泊车高精度轨迹规划,提出一种联立多阶段划分和非均匀Gauss配点参数化的轨迹优化算法。首先,结合车辆泊车动力学方程和约束条件建立了平行自动泊车数学模型;然后,根据泊车过程,提出将泊车过程划分为泊车起动、接近车位、进入车位、姿态调整、泊车落位5个阶段,并建立各阶段对应的不等式约束条件;进一步,在伪谱法算法框架下,结合阶段约束给出了多阶段局部高斯配点策略,以此实现分阶段独立配点离散,从而提高泊车轨迹规划的精准度和适应性;最后,在通用小型汽车模型上在长短车位上进行仿真测试,验证提出方法的正确性和适应性。结果显示,相较于分段区域Gauss伪谱法,改进方法在获得平滑泊车轨迹的同时泊车时间平均减少2.976 s,时间性能提升21.7%,表明了所提算法的有效性。 | 刘平 陈卓 刘明杰 朴昌浩 Jang Soohyun 万凯林 | 2023 | 汽车工程2023，45，7： | 0 |
