Purpose: To investigate the effects of watching three-dimensional (3D) television (TV) on the angle of deviation and refractive error in children with exodeviation. Methods: Twenty-three volunteers with exodeviation, aged 6 to 12 years, without any ocular abnormalities other than refractive error and exodeviation were recruited for this study. The subjects watched 3D TV for 50 minutes at a viewing distance of 2.8 meters. The image disparity of 3D contents was -1 to 1 degree. Refractive errors were measured before and immediately after watching TV and after a 10-minute rest. The changes in angle of deviation were also obtained. Refractive errors and angle of deviation before and after watching 3D TV were compared. Results: The mean age of the subjects was 9.30 ± 1.58 years. The mean baseline angle of deviation was 13.04 ± 5.25 (6-30) prism diopters (PD), which did not change significantly immediately after watching 3D TV and after a 10-minute rest (<EM>p</EM> = 0.452). The mean refractive errors were -2.15 ± 1.55 D in the right eye and -2.06 ± 1.55 D in the left eye before and changed to -2.14 ± 1.57 D and -2.11 ± 1.45 D, respectively, immediately after watching 3D TV. After a 10 minute rest, the mean refractive errors were 2.14 ± 1.53 D in the right eye and -2.07 ± 1.53 D in the left eye. All changes in refractive errors were not statistically significant (<EM>p </EM>= 0.991 in right eye, 0.495 in left eye). The amount of myopic shift in both eyes immediately after watching 3D TV was correlated with the angle of exodeviation (r = 0.468, p = 0.024). However, the correlation disappeared after a 10-minute rest (r = 0.345, <EM>p </EM>= 0.107). Conclusions: Watching properly made 3D contents on 3D TV for 50 minutes at more than 2.8 meters of viewing distance did not affect the refractive error in children with exodeviation. Further studies on the relationship between the amount of myopic shift and the angle of exodeviation are necessary. J Korean Ophthalmol Soc 2014;55(10):1525-1529

서혜진,조윤우,나운우,윤승현,안상호,김수정,최규식,박해운,장성호,손수민 대한재활의학회 2011 Annals of Rehabilitation Medicine Vol.35 No.1

Objective To investigate the pain-related behaviors and the changes of CX3CR1 expression in the dorsal root ganglion (DRG) in a rat model of lumbar disc herniation. Method A total of 90 male Sprague-Dawley rats were used. A laminectomy was performed to expose left L5 nerve roots and corresponding DRG. Autologous nucleus puplosus was implanted on the left L5 nerve root proximal to the DRG without mechanical compression. Sham operation was also done with the same procedure as mentioned above. Thermal hyperalgesia and mechanical allodynia were assessed at 1, 5, 10, 20 and 30 days after surgery. Real time PCR and immunohistochemistry after behavioral test were performed. Results In the lumbar disc herniation rats, significant reduction of thermal withdrawal latency indicating thermal hyperalgesia was shown on the ipsilateral hindpaw on postoperative day 1 (p<0.01) and peaked on day 10 (p<0.05) and maintained throughout day 30 (p<0.05). The reduction of mechanical allodynia threshold, indicating mechanical allodynia, was observed on the ipsilateral hindpaw on postoperative day 1 (p<0.01) and continued throughout day 30 (p<0.01). Real time PCR showed the decrease in mRNA expression of CX3CR1 in the ipsilateral DRG on day 1 (p<0.05) and the significant increase on day 20 (p<0.05). The immunoreactivity for CX3CR1 was also increased in ipsilateral DRG on day 10 and 20. Conclusion These data suggest that lumbar disc herniation induces thermal hyperalgesia and mechanical allodynia and upregulates the expression of CX3CR1 in dorsal root ganglion. Expression of CX3CR1 might be associated with subacute neuropathic pain after intervertebral disc herniation.

영어와 한국어 동화에 따른 영어 단순모음 인지정확성 연구 : 적합성 지표를 중심으로

서혜진 한국언어과학회 2019 언어과학 Vol.26 No.4

The purpose of this paper is to elaborate on the assimilation patterns of Perceptual Assimilation Model-L2(PAM-L2) by adopting the concept of ‘fit index’ conceived by Guion et al.(2000) and explore the variations of foreign speech perception predicted in PAM-L2’s framework. In the experiment, 33 college students participated in the online POSE tests and the results of 6 English vowel pairs ( /i-ɪ/, /ɪ-ɛ/, /ɛ-æ/, /u-ʊ/, /æ-ɑ/, /ʌ-ɑ/) were analyzed. By using the fit indexes, /i-ɪ/ and /ɛ-æ/ pairs were categorized as SC, /u-ʊ/ pair as CG, and /æ-ɑ/ and /ɪ-ɛ/ pairs as TC. The vowel /ʌ-ɑ/ pair was analyzed as UC type and excluded in the discussion. The perception accuracy of TC was 75%, and the perception accuracy was 50% for both CG and SC types. In general, the results substantiate the predictions of PAM-L2. In addition, the results from the POSE test showed lower perceptual accuracy rates than those from the previous studies, which may be resulted by the different types of perception experiments exercised in the research.

신어 정착에 대한 연구-『現代新語釋義』(1922)를 중심으로-

서혜진 반교어문학회 2017 泮橋語文硏究 Vol.0 No.47

본 연구는 1922년에 간행된 신어 자료집 『現代新語釋義』를 통해 신어의 정착 과정을 살펴보고자 하는 목적을 가진다. 이를 위하여 본고에서는 먼저 대상 자료에 대한 이해를 돕기 위해 사전학적 관점에서 표제어를 거시구조와 미시구조로 나누어 살펴보았다. 거시구조는 표제어 배열 기준에서 ‘자모순 배열’, ‘같은 한자끼리의 배열’, ‘같은 의미를 가진 표제어끼리의 배열’이 나타났으며, 이러한 기준들이 서로 혼재되어 사용되었음을 확인하였다. 미시구조는 현대 사전과 같이 면밀하게 분류되어있지는 않으나 동의어, 반의어, 어원, 용례, 약어 등의 정보가 나타났음을 확인하였다. 다음으로 신어의 정착 과정을 살펴보기 위하여 9종의 사전에서 표제어 등재 여부를 확인하였으며, 사전에서의 미등재어는 다시 신문에서의 용례 확인을 진행하여 미정착어를 구분하였다. 그 결과 『現代新語釋義』의 정착어와 미정착어는 각각 680개와 54개로 확인되었다. This study aims to analyze stabilization of listed words through 『Hyeondae Sineo Seogui(現代新語釋義)』 published in 1922. First, This study divided entries into macro structure and micro structure from view of lexicography. Accordingly, in the macro structure, we set ‘alphabetical order arrangement’, ‘arrangement by same Chinese character’, and ‘arrangement by entries with same meaning’ with arrangement criteria of entries. And it was found that the three arrangements were mixed. Micro structure does not show standardized method but information like synonym, antonym, etymology, example, abbreviated word etc. appear in definitions of entries so that readers can understand related information. Second, Discussion of stabilization of entries was progressed through identification of examples shown on dictionary and newspaper. In conclusion, stabilized word and non-stabilized word of 『Hyeondae Sineo Seogui』were 680 and 54 respectively.

담화표지어로서의 oh에 관한 연구

서혜진,이상도 한국언어과학회 2014 언어과학 Vol.21 No.3

This study examines the status of oh as a discourse marker. Fraser(1990, 1999) does not consider oh as a discourse marker because it seems to indicate no relationships between discourses. However, Heritage(1984, 1998, 2002) claims that oh plays a role of discourse marker as a state-of-change token. Other researchers including Schiffrin(1987, 1999), Trester(2009), Tree and Schrock(1999) also suggest that oh be used to reveal the connections between discourses. Oh serves as a discourse marker in two ways: it can be used to imply the change of state of information or knowledge and to reveal the change of state of orientation or awareness. Those two aforementioned functions of oh exemplify the status of oh as a discourse marker

사회학습원리에 따른 집단미술치료가 저소득가정 아동의 자기효능감과 성취동기에 미치는 효과

서혜진,최은영 한국미술치료학회 2014 美術治療硏究 Vol.21 No.4

본 연구는 사회학습원리에 따른 집단미술치료가 저소득가정 아동의 자기효능감과 성취동기 향상에 미치는 효과를 알아보는데 목적이 있다. 이를 위해 D시에 위치한 복지관의 방과 후 프로그램에 참여하는 초등학교 5 ∼6학년 저소득가정 아동 38명 중 자기효능감 척도와 성취동기 척도가 각각 70점 미만인 아동 20명을 구성하여 각 10명씩 실험집단, 통제집단으로 무선배치 하였다. 실험집단을 대상으로 사회학습원리에 따른 집단미술치료 프로그램을 주2회 60분간 총 16회기에 걸쳐 실시하였고, 프로그램 전?후 자기효능감 척도와 성취동기 척도 검 사를 실시하였다. 프로그램의 처치 효과를 알아보기 위하여 각 집단별 사전?사후 척도 점수의 평균과 표준편 차를 산출하고 반복측정 변량분석(ANOVA)을 실시하였으며, 집단과 시기의 상호작용이 나타난 경우 단순 주 효과 분석을 실시하였다. 그 결과 사회학습원리에 따른 집단미술치료가 저소득가정 아동의 전체 자기 효능감과 그 하위영역별 자기효능감 향상에 효과적이었고, 전체 성취동기 향상과 사회적 성취동기 향상에는 효과적이나, 학업적 성취동기 향상에는 효과를 미치지 못한 것으로 나타났다. 즉, 사회학습원리에 따른 집단미술치료가 비 록 학업적 성취동기까지는 영향을 미치지 못하나, 저소득가정 아동의 자기효능감과 사회적 성취동기 향상에 효 과적인 중재방안으로 사료된다.

In Line Plastic-Optical-Fiber Temperature Sensor

서혜진,신종덕,박재희 한국광학회 2021 Current Optics and Photonics Vol.5 No.3

In this paper, we present an in line plastic-optical-fiber (POF) temperature sensor based on intensity modulation. The in line POF temperature sensor is composed of a POF, including an in-fiber micro hole filled with reversible thermochromic material, the transmittance of which depends on temperature. The reversible thermochromic material was cobalt chloride/polyvinyl butyral gel. A cobalt chloride solution of concentration 30.8 mM was formulated using 10% water/90% ethanol (v/v) solution, and gelled by dissolving polyvinyl butyral in this solution. Four types of in line POF sensors, with in line micro holes of four different diameters, were fabricated to measure temperature in the range of 25 to 75 °C. The output optical power of all of these in line POF temperature sensors was inversely proportional to the temperature; the relation between output power and temperature was approximately linear, and the sensitivity was proportional to the diameter of the in-fiber micro hole. The experimental results indicate that an in line POF sensor can be used effectively for measuring moderate temperatures.
