Purpose: This study was undertaken to evaluate if the reduction of intraocular pressure (IOP) observed in a uniocular trial correlates with an IOP reduction observed in the fellow eye. Methods: The study was performed on forty patients with bilateral glaucoma or suspect glaucoma who underwent a uniocular trial of 0.005% latanoprost and subsequently received the same drug in the fellow eye after 1 week. Inter-eye IOP variations were less than 3 mm Hg over two measurements, and were followed minimally for 4 weeks. The uniocular IOP reduction (IOP before medication - IOP after medication) and the net IOP reduction (IOP change in the trial eye after medication - IOP change in the fellow eye) were calculated. The uniocular IOP reduction and net IOP reduction in the trial eye was compared with the results from the fellow eye. Results: The mean uniocular IOP reduction in the trial eye and the fellow eye were 3.6±2.42 mm Hg and 2.78±2.16 mm Hg, respectively (r=0.390, r2=0.152, P=0.013). The mean net IOP reduction in the trial eye and the opposing eye were 3.55±1.70 mm Hg and 3.15±1.83 mm Hg, respectively (r=0.782, r2=0.612, P=0.000). Conclusions: A uniocular drug trial in patients with similar IOPs between their eyes can adequately predict the IOP lowering effect of a medication.

현재 애니메이션 기술이 발전함에 따라 컴퓨터를 활용하여 입체적 사실감이 표현되는 많은 3D 컴퓨터 애니메이션 작품들이 제작되고 있다. 관객의 요구에 따라 더 향상된 퀄리티와 사실감을 전달하도록 기술적인 부분에서 실제의 느낌을 줄 수 있는 사실적 표현의 렌더링 방식이 매우 빠르게 발전하고 있다. 반면에 비사실적 렌더링 방식으로 만화적 요소나 회화적 요소를 강조하는 애니메이션이 등장하고 있는데, 이 같은 비사실적 표현으로 인해 사실적 렌더링에서는 느낄 수 없는 색다른 느낌과 경험을 제공하기도 한다. 3D 애니메이션의 다양한 표현 방식에도 불구하고 국내에서는 검증된 방식, 제작자의 의도나 제작 여건 등의 제한적이고 일방적인 방식으로 렌더링 방식을 결정하고 있다. 본 연구를 통해 애니메이션을 보고 즐기는 주체인 관람객의 입장에서 그들이 요구와 선호하는 방식이 다양하며 서로 다를 수 있음을 설문 분석을 통해 확인하고, 이를 충족하기 위한 다양한 표현 방식의 시도를 제언하고자 한다. 설문 분석을 통해 2D에 비해 3D에 대한 선호도가 높고, 3D 컴퓨터 애니메이션에서 시각적인 화려함은 중요하지만 점차적으로 관람객의 요구는 다양해지고 까다로워지고 있음을 확인하였다. 스토리에 따른 3D 표현 방식에 선호도가 일정한 경향을 띄고 있으나 연령별, 성별에 따라 다양하게 표출되었고 영향을 미치고 정도가 성별보다는 연령별에 따른 선호도의 차이가 분명하게 나타남을 발견하였다. 이 같은 결과를 토대로 기존에 제작 방법을 결정하는데 중요했던 고려 사항에서 탈피하여, 다양한 요구와 취향을 가진 관람객의 관점을 참고하여 작품의 제작방법을 결정하려는 시도와 노력이 필요하다. As technology of animation advances, many works of 3D computer animation by using computer representation of three-dimensional realism are produced. In accordance with the requirements of the audience the photo-realistic rendering to deliver improved quality and realism and to give the impression of the actuality has been developed very fast. On the other hand, non-photorealistic rendering to highlight the cartoonish elements or pictorial elements was emerged, and can provide to feel a different experience with the photo-realistic rendering. Despite various expressions of 3D animation, rendering method has been determined by limited and one-sided way such as proven ways, producer’s intent, production-conditions in Korea. Through this study, in the view of audience who enjoy watching animation, for their needs and preferences are diverse and different from each other through the analysis of the survey to identify, to attempt the various methods of expression is suggested. The results of survey show high affinity for 3D to 2D, and the diverse and demanding needs of audience are increasingly challenging as well as simply visual splendor is important in 3D computer animation. Although the preference of 3D expression method depending on the story has a certain trend, it is expressed with the differences according of age and gender, and degree of influence by age, were found appears clearly rather than gender. Based on these results, move away from the existing production considerations were important, and made an attempt and effort to determine the method of production with the reference of a point of view of the audience who have a diverse needs and tastes.

애니메이션에서 부분적인 비사실적 표현의 활용 사례 - 3D 컴퓨터 애니메이션 중심으로 -

신형호 ( Shin Hyung-ho ) 한국디자인트렌드학회 2013 한국디자인포럼 Vol.40 No.-

1980년대부터 본격적으로 발전하기 시작한 3D 컴퓨터 애니메이션은 짧은 역사에도 불구하고 영화부문에서 중요한 역할을 차지하고 있다. 3D 애니메이션 기술의 눈부신 발전으로 사실적이고 현실감 넘치는 렌더링 기술이 발전하여, 가상의 공간에서 제작되지만 현실과 구별하기 어려운 정도의 극사실적 표현이 가능해졌다. 그러나 너무 사실적이기 때문에 거부감을 일으키는 현상과 비사실적 표현이 지닌 색다른 느낌과 경험을 활용하려는 시도가 진행되었고, 3D로 제작되지만 비사실적 느낌을 주기 위한 다양한 기술이 발전하였다. 본 연구에서는 사실적 3D 애니메이션에서 특별한 목적을 위해 부분적으로 비사실적 표현을 사용한 사례를 통하여 유용성과 효과를 분석하고자 한다. 이를 위해 박스오피스 흥행누적순위 50위안의 장편 애니메이션 중, 3D로 제작되고 부분적으로 비사실적 표현이 사용된 작품을 찾아 분석하였다. 부분적으로 비사실적 표현을 적용한 사례를 통해 역사적 사실, 회상, 꿈, 추억, 미각 등 영상 매체에서 표현하기 어려운 상황을 관객에게 효과적으로 표현하기 위해 비사실적 표현의 장점인 함축성, 간결성, 단절성, 과장성 등의 효과를 활용함으로써 애니메이션 표현력의 범위를 한층 확대 할 수 있는 가능성을 확인하였다. Since the 1980s, development began in earnest 3D computer-animation, despite the short history, occupies an important role in film history. By means of the remarkable development of 3D animation technique and realistic rendering technology, even though everything is produced in virtual space, it is very challenging to distinguish extra-realistic rendering with factual reality. However, because it looks so real that they cause resistance phenomena and non-realistic expression with an attempt to take advantage of diverse feelings and experiences were encountered, a variety of non-realistic techniques were developed in the production using realistic 3D technique. In this study, through the analysis of cases that are partly using non-realistic representation for the special purpose of expression in realistic 3D animation are analyzed the utilization of the situations and effects. For this, the cumulative box office ranking of 50 in 3D animated film with partially non-realistic expressions were used to analyze. Through the analysis of cases of using partly non_realistic expression, the possibility to expand the limits of expression for historical fact, recall, dreams, memories and taste which are difficult to express audience effectively in visual media can be efficiently conveyed by effects of using non-realistic expression such as implication, brevity, exaggeration, discontinuity are presented.

Purpose: This large case study evaluated the success rate of revisional surgery and the causes of failed endonasal dacryocystorhinostomy (DCR) with long-term follow-ups. Methods: One hundred nine patients (114 eyes) who underwent revisional surgery for a failed endonasal DCR at the Department of Ophthalmology, Guro Hospital, Korea University between January 1995 and January 2005 were included in this retrospective study. We evaluated the causes of failed endonasal DCR and their success rates of revisional surgeries. Results: The causes of surgical failure were membranous obstruction (83 eyes), granuloma (22 eyes), synechia (11 eyes), common canalicular obstruction (11 eyes), functional block (7 eyes), and canalicular obstruction (1 eye). The revisional surgeries were silicone tube intubation after granuloma removal, synechiolysis and membranectomy using Nd:YAG laser and trephination of canalicular obstruction, and endonasal conjunctivodacryocystorhinostomy (CDCR) for the parts of functional block and the canalicular obstruction. The overall success rates of the revisional surgeries were 83.3% (95/114 eyes). The mean follow-ups period was 18.97 months (range, 9~113 months). Conclusions: This is the first large case study in Korea on revisional surgery with long-term follow-ups, as far as we know. The overall success rates of endonasal DCR after receiving simple revisional surgery were comparable to those of the standard external DCR.

Purpose: To determine the intranasal causes of failed dacryocystorhinostomy (DCR) and the effects of transcanalicular diode laser-assisted revision surgery. Methods: Twenty-four patients (29 eyes) who underwent revision surgery for a failed DCR at the Department of Ophthalmology, Ansan Hospital, Korea University between March 2009 and February 2011 were included in the present retrospective study. The intranasal causes of failed DCR, the time of symptoms such as epiphora and discharge after DCR, success rates of revision surgeries and follow-up periods were evaluated. Results: Membranous obstruction was found in 25 eyes (86.2%) and was accompanied with granuloma in 10 eyes; these were the most common causes of failed DCR. The mean time for symptom development after DCR was 14.6 months, the success rate of the first revision surgery was 82.1% and good results were obtained in 5 eyes after the second revision surgery. Recurrence developed in 2 eyes, but symptoms improved after the lateral tarsal strip procedure. Conclusions: Membranous obstruction was the most common intranasal cause of failed DCR and transcanalicular diode laser-assisted revision surgery produced good results. Additionally, in patients with persistent epiphora following anatomically- patent revisional surgery, lacrimal pump failure due to lower eyelid laxity should be considered and corrected.

시계열분석을 이용한 한국 오징어 어업의 어획량 분석과 예측

박해훈,신형호 麗水水産大學校 産業技術硏究所 1996 産業基術硏究所 論文集 Vol.5 No.-

한국 오징어 어업에서의 22년간이 월별 어획량 자료에 시계열 분석을 이용하여 어획량을 분석, 예측하였다. 시계열 분석은 다른 생물학적, 해양학적, 사회 경제적인 요소가 없어도 단지 어획량 자료만으로 분석과 예측이 가능하다. 1971∼1990년 사이의 월별 오징어 어획량의 자료를 ARIMA 시계열 모형에 적응시켜 분석한 결과, 다음과 같은 계절 ARIMA 모형식을 구하였다. 로그(대수)변환때 : ?? Box-Cox 변환때 : ?? 위의 두 모형중 로그변환시킨 경우보다 Box-Cox 변환시킨 것이 예측오차가 적었으며, BOX-COX변환식은 ??이었다. 위의 두 모형 중 후자의 모형으로 1991∼1992년에 대해 오징어의 월별 어획량을 예측하였다. 예측 어획량과 실제 어획량과의 월별 오차범위는 0.9∼203%였다. 실제 어획량이 1991년과 1992년에 각각 109,902M/T, 139,792M/T이고, 예측어획량은 78,585M/T과 86,968M/T이었다(1991년의 오차는 24.6%, 1992년에는 27.4%). 2년 동안의 총어획톤수에 대한 오차는 26.2%였다. 또한, 스펙트럼 분석은 순환변동의 주기가 12.5개월, 2.2년 및 5.5년인 성분에서 상대적으로 큰 값을 나타내었으며, 순환변동 성분은 적절한 ARIMA 모형을 결정하는데도 도움을 준다. The seasonal Autoregressive Integrated Moving Average (ARIMA) model and spectral analysis were described to forecast the monthly landings of squid in Korea. The prediction error by the Box-Cox transformation on monthly squid catches in Korea was less than that by the logarithmic transformation. The equation of Box-Cox transformation was ??. the seasonal ARIMA model is presented ?? where : ??=value at month t: ?? is a backward shift operator, that is, ??: and ??=error term at month t, which is to forecast 24 month ahead the squid landing in Korea. Forecast of the monthly squid landings for 1991∼1992 which were compared with the actual landings had an absolute percentage error(APE) range of 11.2∼207.7%. Total observed annual landings in 1991 and 1992 were 109,902M/T and 139,792M/T respectively, while the model predicted 82.816M/T and 101,479M/t (APE 24.6% and 27.4%, respectively). And spectrum analysis of the monthly catches of squid showed some dominant flutuations in the periods of 12.5 month, 2.2 and 5.5 years. The spectrum analysis was also useful for selecting better ARIMA model.
