Despite habitual descriptions such as the first ever Korean student in the United States, Yu Kilchun’s thought reflected in Seoyu gyeonmun (Observations of a journey to the West) has oftentimes been considered as an understanding of Modern knowledge with a ‘Japanese filter,’. In other words, his comments in Seoyu gyeonmun are usually considered as a result of learning about the West not in its original form but with ‘Japanese-translated’ works. A major portion of Seoyu gyeonmun does show translations of Japanese writings, while traces of his own consulting of English-language sources are rather scarce. That led to scholars to consider the possibility of his study in U.S. having any sort of real bearing or influence on his thinking as ‘minimal’ or ‘probably’ at best. Yet an extensive examination of all the sources of Yu’s references made in the first and second chapters of Seoyu gyeonmun reveals that Yu Kilchun did consult U.S. High School Geography textbooks at least in his writing on World Geography. Six out of nine parts of Seoyu gyeonmu n’s first two chapters were translation of David Warren’s An Elementary Treatise on Physical Geography. Yu Kilchun studied modern geography using the same textbook alongside U.S. students at Dummer Academy, and apparently integrated the results of his study into the first two chapters of Seoyu gyeonmun. In other words, contents of these two chapters were not a rehash of a Japanese interpretation of the same source. It was a result of Yu’s own seeing, hearing and studying of U.S. contents during his stay in the country. The fact that he translated a textbook at Dummer shows us that his stay in the U.S. not only provided him with an opportunity to hone his English or superficially experience the Western culture, but also prompted him to embrace modern knowledge rather directly, and not using any Japanese proxy or media.

Background: The pattern of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-mediated neurotoxicity (necrosis vs apoptosis) and the neuroprotective effect of propofol on AMPA-mediated neurotoxicity are still unclear. Methods: Thirteen-day-old primary rat mixed cortical cultures were used. To measure the neuroprotective effect of propofol, AMPA (50 μM), AMPA (50 μM) plus propofol (0.1, 1, 25, 50 μM), AMPA (50 μM) plus DMSO, propofol (50 μM) and DMSO were administered (n=45). Seventy-two h later, surviving cells were counted using trypan blue staining and were converted to cell death rate (CDR). To measure the effect of propofol (50 μM) on AMPA (50 μM)-induced apoptosis, a triple stain was done. In a fixed field (×400), the number of neuronal cells stained by neuronal nuclei (NeuN) and Hoechst staining and apoptotic cells stained by terminal deoxynucleotidyl transferase mediated dUTP nick-end-labeling (TUNEL) assays were counted. Apoptotic cell rates (ACR) were also calculated. Statistical analyses were performed using one way-analysis of variance followed by Bonferroni`s test. P<0.05 was considered statistically significant. Results: AMPA (50 μM) stimulation demonstrated 49.3% CDR, and adding propofol 50 μM decreased CDR to 29.4% (P<0.05). In the TUNEL assay, cells with no drug treatment demonstrated 12.3% ACR and 50 μM AMPA increased ACR to28% (P<0.05). Adding 50 μM propofol to AMPA decreased the ACR to 20.1% (P<0.05). Conclusions: Propofol (50 μM) had neuroprotective effects against AMPA (50 μM)-induced cell death by reducing apoptosis. (Korean J Anesthesiol 2008;55:607~12)

Evaluation of NOAA/NESDIS Auto-Estimator for Heavy Rainfall Events over Korean Peninsula

서명석,이정림,곽종흠 한국기상학회 2004 Asia-Pacific Journal of Atmospheric Sciences Vol.40 No.6

This paper presents the evaluation results for adaptation of the auto estimator(A-E), which being developed for the real time monitoring and forecasting of heavy precipitation over the US, to the Korean peninsula. The statistical evaluation of A-E algorithm is performed using the 400 points of automatic weather station net-work data and GOES-9 infrared cloud top temperature for the selected 8 heavy rainfall cases. Preliminary results on the potential application of the A-E algorithm to heavy rainfall over the Korean peninsula are encouraging. The correlation coefficients of 8-case average, the best and the worst case are 0.52, 0.67 and 0.43, respectively. And the 8-case averages of bias ratio, root mean square error ratio, probability of detection and false alarm ratio are 0.28, 2.1, 0.59 and 0.34 for 1 h sampling interval. Sensitivity analysis shows that the best temporal sampling interval, method, and spatial sampling size are 60minutes, current and 7x7 pixels, respectively. However, the performance of A-E algorithm is clearly dependent on the both types and development stages of rainfall system. The A-E algorithm shows a reasonable performance for the well defined and short lived convective systems but does poor results for the long lived stratiform cloud systems. The performance is better during the mature stage than the developing and decaying stages of rainfall system. More efforts are needed to minimize the false alarm ratio and correct the strong dependency on the types and stages of rainfall system. 본 연구에서는 미국 해양기상청 (NOAA/NESDIS)에서 개발하여 운용중인 집중호우시의 강우율 자동추정 알고리듬의 한반도 적용 가능성에 대해서 분석하였다. GOES-IR 구름꼭대기 온도 값과 자동기상관측소 (AWS) 측정값을 이용하여 강우율 자동추정 알고리듬의 강우량 추정 성능을 통계적으로 분석하였다. 다양한 사례에 대한 강우량 추정 수준을 분석하기 위하여 2003년 7월부터 8월사이 일 강우량이 80 mm 이상인 집중호우 8개 사례를 선정하였다. 강우율 자동추정 알고리듬의 한반도에서의 집중호우에 대한 적용 가능성의 예비 분석결과는 매우 긍정적이다. 예를 들어 8개 평균, 가장 좋은 사례와 가장 나빴던 사례에서의 상관계수가 각각 0.52, 0.67 그리고 0.43으로 나타나 모든 사례에서 통계적으로 유의성이 있는 것으로 나타나고 있다. 또한 8개 전체 사례의 평균 편의비율 (bias ratio), 오차제곱근비율 (RMSE ratio), 강수 검색 확률 (probability of detection), 및 강수 검색 오류 비율 (false alarm ratio) 이 각각 0.28, 2.1, 0.59와 0.34이다. 이 값들은 강우의 강한 시공간 변동성과 무강우 화소를 제거하기 위하여 어떠한 보정도 하지 않은 점을 고려할 때 비교적 양호한 것으로 판단된다. 강우량의 누적시간과 IR 영상에서 화소 크기에 대한 민감도 연구결과 IR 영상은 영상관측시를 기준으로 전후 30분 합 (총 60분)에 대해서 강우량 추정수준이 가장 높았으며 AWS 관측점 자료는 일반적으로 GOES 적외영상의 7x7화소의 평균을 취하였을 때 강우율 추정이 가장 양호하였다. 그렇지만, 강우율 자동추정 알고리듬의 추정수준이 강우 시스템의 종류 및 발달단계에 따라 다양하게 나타나고 있다. 즉, 강우량 자동추정 알고리듬은 단기간에 발달하여 집중호우를 유발하는 대류성 강우 시스템에 대해서는 강우량을 양호하게 추정하나 광범위한 지역에서 장시간 지속되며 구름꼭대기 온도가 높은 층운형 강우에 대해서는 강우강도를 관측보다 현저히 낮게 추정하고 있다. 또한 이 알고리듬은 강우 시스템의 시작과 종료 시점보다는 성숙단계일 때 추정수준이 높게 나타나고 있다. 따라서 이 알고리듬의 현업적 이용을 위해서는 우선적으로 무강우 화소의 제거기법 개발과 강우 시스템의 종류 및 발달단계에 따라 변하는 문제점을 보정하는 기술의 개발이 필요하다.

This study was performed to investigate the reproductibility of eccentric mandibular movements according to preferred chewing side, range of mouth opening, type of lateral guidance and involvement of temporomandibular disorders. 50 patients with temporomandibular disorders and 65 dental students without any signs and symptoms were randomly selected for this study as the patients group and the control group, respectively. For recording and observation of eccentric mandibular movement trajectory, BioEGN$^\textregistered$ of Biopak$^\textregistered$ system (Bioresearch Inc., USA) was used. Each eccentric movement to anterior, right and left side was performed three times similar to the movement pattern for Pantronic Reproducibility Index. mandibular path was analyzed by three dimensional positional change and the three paths from one direction were compared with one another. From this, reproducibility index of one-directional lateral movement could be calculated, and total reproducibility index, named BioEGN reproducibility index(BERI), was also computed from three-directional eccentric movement likewise. BioEGN reproducibility Index could have four value of score by small or large scale, and by outgoing or incoming movement. The data were analyzed by SAS/stat program and the results obtained were as follows: 1. Right side chewing subjects showed more consistent pattern In reproducibility index in comparison between patients group and control group than left chewing subjects have done, and reproducibility was low in patients group. However, there was no difference between the two stoups in bilateral chewing subjects. 2. There were no difference in reproducibility index between preferred chewing side and contralateral side in unilateral chewing subjects whereas reproducibility index in left side on outgoing movement were higher than in right side in bilateral chewing subjects. 3. Difference in total reproducibility index(BERI) between canine guidance group and non-canine guidance group were not observed though difference in reproducibility index on lateral movement were observed in part. 4. There were no difference in reproducibility index between affected side and contralateral side in unilaterally affected patients, and between unilaterally affected patients and bilaterally affected patients in patients group. 5. Highly significant positive correlationship were shown among the four 쇼pes of total reproducibility index(BERI) in total subjects, and range of clinical mouth opening was negatively correlated with BEBI on outgoing movements and with index on outgoing movement to preferred side.
