Purpose: To study the short-term visual outcomes affected by the patterns of macular edema in retinal vein occlusion patients. Methods: In a retrospective study, 33 eyes of 33 consecutive patients with macular edema from retinal vein occlusion received an intravitreal injection of bevacizumab. Macular edema was classified according to OCT patterns and the effect on visual outcome evaluated: Diffuse macular edema (DME) vs. focal macular edema (FME), and macular edema with serous retinal detachment (SRD) vs. macular edema without serous retinal detachment (non-SRD). Results: Nine patients had CRVO, 24 patients had BRVO and the follow-up period was 3.6 months. In the FME group, the mean baseline BCVA was 0.61 ± 0.34 and the final BCVA was 0.26 ± 0.29, a difference that was statistically significant (p < 0.01). In the DME group, the mean baseline BCVA was 0.85 ± 0.44 and the final BCVA was 0.73 ± 0.37, a difference that was not statistically significant (p = 0.07). In the non-SRD group, the mean baseline BCVA was 0.76 ± 0.43 and the final BCVA was 0.38 ± 0.36, a difference that was statistically significant (p < 0.01). In the SRD group, the mean baseline BCVA was 0.73 ± 0.40 and the final BCVA was 0.64 ± 0.42, a difference that was not statistically significant (p = 0.07). Conclusions: Visual outcome was significantly better in the FME and non-SRD groups. The patterns of macular edema measured according to OCT were a prognostic factor for visual outcome.

Purpose: To investigate whether there is a difference in ON- and OFF-responses of the photopic electroretinogram (ERG) in glaucomatous eyes. Methods: Photopic ERG and optical coherence tomography were performed in 15 normal, 13 glaucoma suspect, and 22 glaucoma subjects. Amplitudes and implicit times for a, b, d, i, photopic negative response (PhNR), and retinal nerve fiber layer thickness were compared among the three groups. Results: The PhNROFF amplitude (μV) was 19.05 ± 11.41 in the glaucoma group, 14.24 ± 10.37 in the glaucoma suspect group, and 2.69 ± 12.16 in the normal group, demonstrating a significant difference among the three groups (p < 0.01). The PhNRON amplitude (μV) was 20.15 ± 13.99 in the glaucoma group, 31.49 ± 17.09 in the glaucoma suspect group, and 37.59 ± 9.53 in the normal group, a significant difference (p < 0.01). However, there was no significant difference between the three groups. The ON-OFF response PhNR amplitude was correlated with retinal nerve fiber thickness (r = 0.481, r = -0.480, respectively), and areas under the receiver operating characteristic curve were 0.782, and 0.718, respectively. Conclusions: There is a potential role for the ON-OFF response PhNR in early detection of glaucomatous damage. J Korean Ophthalmol Soc 2012;53(8):1104-1111

박가희,가순호 국제지역학회 2022 국제지역연구 Vol.26 No.1

본 연구의 목적은 한국과 수출대상국의 문화적 유사성과 농수산물 및 식품 수출과의 관계를 파악하고자 하는데 있다. 기존 연구가 문화적 유사성과 총수출액의 관계 분석을 다루고 있는데서 나아가 본 연구는 농수산물 및 식품 수출을 수출 다양성과 수출 집중도로 분해함으로써 어떤 경로로 수출이 증가하는지를 살펴본다. 이를 위해 2001-2015년 한국의 수출 자료를 바탕으로 수출 다양성과 수출 집중도를 계산하고, Hofstede 문화차원지수를 이용해 문화적 유사성을 측정하였다. 분석결과 한국과 수출대상국의 문화적 유사성이 낮으면 수출의 다양성이 감소하는 것으로 나타났다. 또한 선진국의 경우 문화적 유사성이 낮더라도 수출 다양성과 수출 집중도가 증가하지만, 개도국의 경우 문화적 유사성이 낮으면 수출 다양성과 수출 집중도도 감소하는 것으로 분석되었다.

강박 경향자의 기억확신과 확인행동에 대한 행동개입과 인지개입의 효과 비교

박가희,윤혜영 한국인지행동치료학회 2021 인지행동치료 Vol.21 No.4

The purpose of this study was to find out if there were any changes in memory confidence, memory performance, and checking behaviour when exposed to two different types of intervention targeted at individuals with OCD tendencies who have checking behaviour. Firstly, the slow motion technique which is one of the techniques used in behavioural intervention. Secondly, strengthening beliefs about memory which is one of the techniques used in cognitive intervention. These two techniques were compared in order to confirm whether or not strengthening beliefs about memory is more effective in reducing obsessive compulsive symptoms than the slow motion memory technique. In particular, this study sought to extend the scope of memory performance and memory confidence to include not only retrospective memory, but also to include prospective memory in order to identify the impact on the overall functioning of memory capabilities. In total, there were 27 participants, all of whom were in their 20s and had scored more than 29 points in the Padua Inventory(PI). The participants of this study were randomly assigned to slow motion technique intervention(SI) group (n = 15) or beliefs about memory intervention(BI) group (n = 12). The results of this study are summarized as follows. There were no significant differences between groups in both memory performance and memory confidence in terms of retrospective and prospective memory. However, checking behaviour time was significantly reduced in BI group compared to SI group. This means that the cognitive intervention method, which emphasizes the collection of evidence for objective memory and having confidence in the memory retrieval processes, was more effective in reducing checking behaviour time than the behavioural intervention method which makes participants behave slowly. 본 연구의 목적은 확인행동을 주로 나타내는 강박 경향자들을 대상으로 행동개입 중 하나인 강박행동 둔화 개입과 인지개입 중 하나인 기억에 대한 믿음 개입을 실시했을 때 기억확신, 기억수행, 확인행동에서 변화가 있는지 알아보고, 기억에 대한 믿음 개입이 강박행동 둔화 개입보다 강박 증상 감소에 더 효과적인지 확인하는 것이었다. 특히 기억수행과 기억확신의 범위를 과거경험뿐 아니라 미래계획까지 확장하여 기억 능력의 전반적 기능에 미치는 영향을 확인하고자 하였다. 참가자는 강박질문지(PI)에서 29점 이상을 기록한 20대 27명이었고 강박행동 둔화 개입 집단(n=15)과 기억에 대한 믿음 개입 집단(n=12)에 무선할당 되었다. 본 연구의 결과는 다음과 같다. 과거경험 및 미래계획에 대한 기억수행과 기억확신 모두에서 집단 간 유의한 차이가 나타나지 않았다. 그러나 강박행동 둔화 개입 집단에 비해 기억에 대한 믿음 개입 집단에서 확인행동 시간이 유의하게 감소하였다. 이는 객관적인 기억에 대한 증거를 모으고 자신의 기억에 대해 확신감을 가질 것을 강조하는 인지개입 방식이 행동을 천천히 하도록 하는 행동개입 방식과 비교했을 때 확인행동 시간 감소에 더 효과적이었음을 의미한다.

박가희,박리라,송종우,Park, Gahee,Park, Rira,Song, Jongwoo 한국통계학회 2017 응용통계연구 Vol.30 No.1

최근 경륜은 2015년도 기준, 5백만 명 이상의 많은 사람들이 참여하고 2조를 넘어선 매출을 발생시키는 대중적인 레저스포츠로서 자리 잡고 있다. 본 연구의 목적은 다양한 통계적 분석기법을 사용하여 경륜경기의 순위를 예측하고, 순위에 유의한 영향을 미치는 변수들을 파악하는 데에 있다. 다양한 Classification 방법과 Regression 방법들을 적용하여 순위예측모형을 만들고 비교분석하였다. 대부분의 모형에서 공통적으로 선택된 변수들을 살펴보면, 등급이 강급될수록, 종합득점이 높을수록 순위가 높아지며 반대로 등급이 승급될수록, 번호 4번을 부여받을수록 그리고 최근성적의 순위가 낮을수록 순위가 낮아지는 것을 알 수 있었다. 또한, 선수의 실력과 관련된 연속형 변수들을 각 경기별로 평균값을 빼서 보정한 자료와 원자료를 사용하여 모형을 적합시킨 결과 모든 모형에서 보정된 자료를 사용하였을 때 더 낮은 오분류율을 보였다. 마지막으로 분석에 사용하지 않은 최근 한 달 경기결과를 예측해서 베팅했을 때 모든 경우에 예측률은 높았지만 큰 이익을 거두지 못했는데 그 이유는 낮은 배당률을 가진 경기의 결과만을 잘 예측했기 때문이다. Over 5 million people participate in cycle racing betting and its revenue is more than 2 trillion won. This study predicts the ranking of cycle racing using various statistical analyses and identifies important variables which have influence on ranking. We propose competitive ranking prediction models using various classification and regression methods. Our model can predict rankings with low misclassification rates most of the time. We found that the ranking increases as the grade of a racer decreases and as overall scores increase. Inversely, we can observe that the ranking decreases when the grade of a racer increases, race number four is given, and the ranking of the last race of a racer decreases. We also found that prediction accuracy can be improved when we use centered data per race instead of raw data. However, the real profit from the future data was not high when we applied our prediction model because our model can predict only low-return events well.
