Purpose: To evaluate the expression of nerve growth factor (NGF) in the rat cornea and lacrimal gland before and after corneal epithelial wounding. Methods: Twenty-nine Sprague-Dawley male rats were used in the present study. Corneal trephination was performed using a 4.0-mm diameter trephine before scratch and at 24, 48, 72 hours after debridement. The lacrimal gland was excised before scratch and at 24 hours after epithelial debridement. NGF levels of the excised cornea and lacrimal gland were measured in rat corneas by enzyme-linked immunosorbent assay (ELISA). Immunohistochemistry staining was performed on rat corneas and lacrimal glands. Results: The NGF/total protein ratio (NGF/tP) increased after wounding in the cornea and lacrimal gland. NGF levels in the cornea significantly increased in the wounded group until the 2nd day after wounding (p < 0.05). After NGF concentration peaked on the 1st day, there was a progressive decline after wounding. Additionally, the NGF concentration in the lacrimal gland of the wounded group was significantly higher than that of the control group at 24 hours after epithelial debridement (p = 0.001). Immunohistochemistry staining showed that NGF staining was stronger in rat corneas and lacrimal glands after epithelial debridement than before. Conclusions: Expression of NGF increased in rat corneas and lacrimal glands after corneal epithelial wounding, which suggests that NGF may play an important role in corneal wound healing.

The purpose of this study was to explore the relationship between elementary school teacher``s science pedagogical knowledge level and student’s science anxiety. The study encompassed four schools in Seoul and Gwangju involving 5th and 6th grade students. It was to investigate their science pedagogical knowledge and science anxiety. Pedagogical questionnaires using Park Sung Hye``s questionnaires(2003) and science anxiety questionnaire using SAMS(1992) were utilized. The survey results were correlated using the SPSS 12.0 analysis program. The main conclusions of this study revealed the following: First, science pedagogical knowledge is associated with teachers`` major. Science pedagogical knowledge level of those who majored in science or engineering was slightly higher than the teachers who majored in humanities or social arts. Second, with science anxiety, both grade level and gender were indicators of significant differences. There was a tendency for the 6th grade and/or female students to have higher science anxiety and for it to be lower in 5th grade and/or male students respectively. Finally, There was a negative correlation between the teacher``s science pedagogical knowledge levels and students`` science anxiety. Through the above studies, the relationship between science pedagogical knowledge level of teachers and science anxiety of students were confirmed. Science teachers want their students to learn science while maintaining a low level of science anxiety. If teachers increase their science pedagogical knowledge level in order to reduce the students`` burden of learning content, the students`` reduced learning anxiety will increase learning satisfaction.

Purpose: To report 2 cases of thick, late-onset and long-standing epithelial ingrowth after laser-assisted in situ keratomilusis (LASIK) using mitomycin C-assisted photorefractive keratectomy and flap suturing. Case summary: The first case involved a 29-year-old woman who had LASIK in both eyes in 2002. She was diagnosed with epithelial ingrowth OD after blunt ocular trauma in 2007. The second case involved a 30-year-old man who had LASIK in both eyes in 1999 followed by enhancements in 2004. Slit lamp examination showed dense epithelial ingrowth OS in a geographic pattern. Two eyes of the 2 patients with epithelial ingrowth had flap lifting followed by debridement of interface epithelial cells, photorefractive keratectomy, interface application of mitomycin C, and the placement of interrupted 10-0 nylon sutures. Two eyes regained better uncorrected visual acuity and showed reduced corneal astigmatism postoperatively. There was no evidence of residual or recurrent ingrowth throughout the follow-up period (case 1: 11 months, case 2: 1 month). Conclusions: Combined mitomycin C-assisted photorefractive keratectomy and flap suturing can be an effective and safe method for treating and preventing the recurrence of thick, late-onset and long-standing epithelial ingrowth involving the visual axis.

Purpose: To evaluate the short-term efficacy of intravitreal ranibizumab injection in eyes with macular edema secondary to central retinal vein occlusion (CRVO). Methods: The records of 17 patients (17 eyes, 11 ischemic, six ischemic) who received an intravitreal ranibizumab injection for macular edema secondary to CRVO were retrospectively analyzed. The ophthalmic examination included best corrected visual acuity (BCVA) and central macular thickness (CMT) at baseline and follow-up visits. Results: After intravitreal ranibizumab injection, the mean BCVA improved from log MAR 1.25 ± 0.47 at baseline to log MAR 0.78 ± 0.49 at 4 weeks and to log MAR 0.81 ± 0.52 at 12 weeks (p < 0.05). Additionally, the mean CMT decreased from 679.4 ± 230.5 μm at baseline to 224.4 ± 129.9 μm at 4 weeks and to 271.6 ± 174.1 μm at 12 weeks (<em>p</em> < 0.001). In subgroup analysis, the decreases in CMT at 4 weeks and 12 weeks were similar in ischemic CRVO and non-ischemic CRVO, but no significant changes in visual acuity were found at 12 weeks in the ischemic CRVO group (<em>p</em> = 0.138). Ten eyes (58.8%) did not require re-injections for macular edema for up to 12 weeks. Conclusions: Intravitreal ranibizumab injection appeared to be an effective option for the treatment of macular edema secondary to central retinal vein occlusion.

모리스 메를로-퐁티의 현상학과 윤리학

신혜영(Hye-Young Shin) 한국현상학회 2016 철학과 현상학 연구 Vol.68 No.-

본 연구의 목적은 모리스 메를로-퐁티의 현상학이 함축하고 있는 윤리학을 밝히는 것이다. 비록 메를로-퐁티가 윤리학에 대한 체계적 저술을 단 한편도 남기지 않았을 뿐만 아니라 ‘도덕적 주체’에 대한 사유를 주도적으로 전개하지는 않았다 하더라도, 그의 신체 주체론은 새로운 윤리학의 모습을 보여줄 ‘도덕적 주체’ 개념을 내포하고 있다. 경험의 애매성을 존중하며 철학적 물음의 힘을 강조하는 메를로-퐁티는 영혼과 신체라는 이중의 본성을 지니고 있으며 세계 속에 뿌리박고 있음이라는 우리 인간의 조건을 역설하면서, ‘육화된, 익명적인, 개별적인 주체’라는 개념을 확립한다. 육화된, 익명적인, 개별적인 주체는 언제나 어떤 간격을 포함하고 있고, 이 간격 속에 세계로의, 타인에로의 열림이 있다. 세계에로의 존재로서의 주체들인 나와 타인은 서로를 잠식하고 얽혀 들어가면서 상호주체성을 형성한다. 전(前)주체와 주체 사이에는 언제나 임박해있고 사실상 결코 실현되지 않는 가역적 운동이 있다. 주체는 고정성이 없이 만들어지고 있다. 나와 타인은 생겨나고 있는 주체들인 것이다. 이렇게 관계 속에서 주체가 만들어지듯이, 관계 속에서 도덕성이 만들어진다. ‘도덕적 주체’는 상호이익을 생각해야 하지만, 나와 타인의 관계가 언제나 도덕적인 것은 아니다. 그러나 언제나 비도덕적인 것도 아니다. 주체가 상호주체성을 이미 그 속에 내포하고 있는 이상, 주체는 타자와 대립적 관계를 형성하지 않는다. 상호성을 특징으로 갖는 주체는 타자를 염려하는 도덕적 주체일 수밖에 없다. 상호성이 따라야 할 보편적 규범은 없다. 하지만 타자를 염려하는 주체는 관계 속에서 도덕성을 만들어 나간다. 요컨대, 메를로-퐁티적 윤리학은 공존재적 관계맺음의 원리의 근거와 기준을 상호주체성에 두고, 세계에의 우리의 소속, 경험 그리고 관계를 강조하는 윤리학으로서, 윤리 혹은 도덕의 근거와 기준을 초월성에 요청하는 윤리학을 대체하는 새로운 윤리학이다. This study aims at elucidating an ethics that Maurice Merleau-Ponty’s phenomenology implicates. He didn’t leave a systematical work about his ethics. Thus, he didn’t develop thoughts about the ‘moral subject’. However, his theory of body-subject includes a notion of ‘moral subject’ that will make a new ethics appear. Merleau-Ponty, appraising the ambiguity of experience and stressing the power of philosophical inquiry, emphasizes our human condition: the human being is mind and body, living in the world. Based on these facts, his concept of an ‘incarnate, anonymous, individual subject’ is established. This incarnate, anonymous, individual subject always includes a gap that is an opening to the world and the others. Subjects as being to the world, I and others are encroached upon and interlaced with each other: intersubjectivity is formed. Between pre-subject and subject, there is a reversible movement that is always imminent, but never actually realized. I and others in whom subjects are being made are the creating ones. As subjectivity is made in relations, also is morality made in relations. A ‘moral subject’ has to consider mutual profits. Nevertheless, the relation between I and others is not always either moral or immoral. A subject does not have conflicts with others because it already includes an intersubjectivity. A subject, characterized by reciprocity, must be a moral one concerning others. There are not universal norms that reciprocity has to follow. Therefore, a subject in this sense builds morality in relations. To sum up, intersubjectivity, the principle of relationship and coexistence, is a basis of Merleau-Ponty’s ethics. It emphasizes our habitation, experience and relationship in the world. It can be a new ethics that substitutes for the ethics presupposing a transcendental as its basis and standard.

수출형 원전 적용을 위한 유럽형 비파괴검증기술 고찰

신혜영(Hye-Young Shin),양원석(Won-Seok Yang),서정관(Jeong-Kwan Suh) 한국비파괴검사학회 2018 한국비파괴검사학회지 Vol.38 No.4

원자력발전 기술은 후쿠시마 원전 사고 발생에도 불구하고 가속화되는 지구온난화에 대처하고 인류의 지속적인 에너지 니즈에 대응하기 위한 최선의 검증된 실용 기술로 받아들여지고 있다. 따라서 노후 원전을 대체해야 하는 원자력 선진국과 새로운 발전원으로 삼고자 하는 신규 원전 도입국의 원전 건설 수요는 당분간 지속될 것으로 기대된다. 우리나라는 90년대부터 원전기술자립을 추진한 결과 2009년 12월 APR1400 4기를 최초로 UAE에 해외 수출한 이래 40년간의 안정적인 원전 건설/운영 경험을 바탕으로 신규 수요가 예상되는 유럽 등 해외시장에서의 원전 건설 수주 확대를 도모하고 있다. APR1400 기반 설계 기술은 2017년 유럽사업자요건(EUR) 부합성 인증서를 취득한 바 있으나 유럽 원전 수주 시장에서의 경쟁력을 제고하고 실질적인 건설에 대비하기 위해서는 설계뿐 아니라 기기 제작 및 건설관련 유럽형 코드 및 기술기준과의 부합성을 설계단계에 미리 확보해야할 것이다. 본 연구에서는 ENIQ 방법에 기초한 유럽형 비파괴검증 기술을 고찰하고 해외 경쟁노형의 적용사례를 조사/검토함으로써 우리나라 수출형 원전의 유럽시장 진출을 위한 비파괴검증기술 분야의 대응 전략 및 방안을 제시하고자 한다. Nuclear power generation technology is still being considered, in spite of the Fukushima accident, as the best realistic energy solution to cope with the global warming crisis and respond to the increasing global demand for energy consumption. Therefore, there is need for additional nuclear power plant (NPP) construction, which is expected to continue increasing. Since the first export of APR1400 to the UAE in a continuing effort to achieve nuclear technology self-confidence, Korea has been considering additional exports of APR1400 to the global NPP market. APR1400 is a design based technology that has successfully completed the assessment process and finally acquired EUR Certification in 2017; however, obtaining compatibility with European code and standards for components manufacturing and construction is essential for competition in the European market. This study reviews the European non-destructive examination inspection qualification technology based on ENIQ methodology, compares this process with domestic practices, investigates cases for other competitive reactors, and finally identifies considerations and strategies to obtain better confidence on inspection quality of APR1400.

화석연료의 문제점을 보완하고 있는 태양광발전 시스템은 태양전지 모듈의 온도에 따라 출력량이 급격히 변화하는 특성을 가지고 있다. 이러한 특성을 잘 이해하고 전력생산을 극대화 하기위해 태양전지의 온도를 낮추기 위한 방법을 고려하였다. 본 논문에서는 모듈의 앞면과 뒷면에 똑같은 온도 감소 설비를 한 후 뒷면의 온도를 낮추는 것이 발전량에 더 큰 도움을 준다는 결론을 도출하였다. Photovoltaic system that is overcoming the problem of fossil fuel, changes the output quantity rapidly according to the temperature of module. so, we studied this principle and considered the method making lower the temperature of module for maximization of electric power production. In this thesis, we concluded that, we fit on below and upper direction of the module to decrease at the same temperature. lower temperature of below direction is more useful for the generating quantity.
