Purpose: To evaluate the effect of clear corneal incisional size on astigmatism during cataract surgery. Methods: Randomized prospective study of 78 patients (108 eyes) who had received cataract surgery for a corneal astigmatism over against-the-rule (ATR) 1.0 Diopter (D) was performed. The eyes were checked by corneal topography and autorefractor preoperatively and one week, one month, two months, and six months postoperative. Group 1 included patients who received an inserted foldable intraocular lens (IOL) through a 2.8 mm incision, and Group 2 included patients who underwent IOL implantation through a corneal incision enlarged to 4 mm. Results: Postoperative visual acuity showed a better visual acuity in Group 2 at both one week postoperatively (0.598±0.352 vs., 0.713±0.345, for Groups 1 and 2, respectively, p=0.046) and one month postoperatively (0.604±0.237 vs., 0.791±0.242, respectively, p=.043). There were no statistically significant differences between the groups after two and six months (p=.135, .087). Postoperative astigmatism measured by corneal topopgraphy showed 1.62±0.44D and, 0.94±0.30D for groups 1 and 2 respectively, (P=.045) at 2 months, and 1.73±0.45 D and, 0.92±0.34 D (P=.042) at six months. These results showed a statistically significant amount of residual astigmatism in Group 2. Autorefractor measurements showed similar results. There were no complications, such as wound leakage, resulting from the increased incision size. Conclusions: Widening of the incision during cataract surgery can reduce corneal astigmatism without significant complications. J Korean Ophthalmol Soc 2010;51(4):510-515

전소희(Jeon sohee),이재연(Lee jaeyeun) 한국열린유아교육학회 2002 열린유아교육연구 Vol.7 No.3

성장ㆍ발달해 가는 과정 속에서 자연스럽게 부딪힐 수 있는 심리적 갈등 혹은 어려움뿐 아니라 다양한 원인들로 인해 발달적ㆍ임상적 측면에서 어려움을 겪고 있는 아동들에게 상당의 한 기법인 독서치료는 매우 효과적인 치료방법이다. 외국의 경우 그 효과성이 활발히 검증되고 있고 독서치료를 더욱 효과적으로 활용하기 위해서 치료자의 역할이 중요하다고 언급함에도 불구하고, 아직까지 국내에서는 독서치료에 관한 연구 및 현장에서의 독서치료 적용이 활발하게 이루어지고 있지 않은 실정이다. 따라서 아동상담자의 독서치료 활용현황과 독서치료에 대한 아동상담자의 인식수준을 파악하고, 아동상담자의 독서치료 인식수준에 따른 독서치료 활용가능성을 살펴봄으로써 많은 아동들이 적절한 시기에 도움을 받을 수 있도록 하는데 그 목적이 있다. The purpose of this study is to understand what extent child counselors are aware of the bibliotherapy to and how they can apply it to their sessions. The survey was taken by the child counselors who are currently active in the field. 150 questionnaires were distributed in the survey, but only 126 of them were properly filled out and used in the study. The questionnaire is primarily composed of questions that would gather information on how often bibliotherapy should be applied to child counseling and how much child counselors are aware of the bibliotherapy. The data were analyzed by using Cronbach ?, frequency, percentage, one-way ANOVA, Duncan multiple comparison method and x2tests. The results of this study are as follows: First of all only 15.9% of the survey participants apply the bibliotherapy to their session. And also only 17.46% of the participants take classes for bibliotherapy. However, most of the participants expressed that they want to learn about bibliotherapy and they are looking forward to applying it to their practices. Second, the degree of the participants awareness on bibliotherapy differs in their work locations and their counseling experience. The survey indicates that the counselor who works in the consultation facility of university possesses higher degree of awareness than that of the counselor who works in hospitals. The survey also shows that the participants with 3 to 6 years of experience apply the bibliotherapy to their practice more actively than those who with less than 3 years or more than 6 years of experience. It was shown that the counselor who works on consultation attached to university shows higher awareness than the counselor who works at hospital. Third, in this survey, they expressed willingness to learn bibilotherapy, which differs, again, in their work locations and their counseling experience. It shows that the counselors who work at consultation were more willing to get educated. Finally, in the result of having seen the difference in counselor's awareness on bibliotherapy according to application, it was shown that higher awareness group were willing to applicate each counselling session.

A conventional OLED has only about 20 % light extraction efficiency. When a photonic crystal layer is put in between the anodic layer and the substrate, the light can be extracted to the air by the optical diffraction phenomena. In this article we form a photonic crystal layer (nano-patterned array) directly on the transparent substrate by the UV-nanoimprinting method with a polymer resin. By the FDTD simulation the enhancement of the light extraction is assessed. And the fabrication process details including UV-nanoimprint, SixNy interlayer and OLED layers are presented in this article. The experiment shows that with the imprinted photonic crystal structure the light extraction efficiency is increased by ~50% comparing with the conventional OLED and therefore this nanoimprinted photonic crystal OLED is a promising technology for the future OLED display and illuminator applications.

목적: 마이봄샘 기능부전을 포함한 안구건조증 환자를 대상으로 펄스광선 치료(intense pulsed light;IPL)를 시행한 후 안구건조증에 대한 임상적 분석을 통해 치료 효과를 알아보고자 하였다. 대상과 방법: 마이봄샘 기능부전으로 진단된 환자 62명 124안을 대상으로 후향적 연구를 시행하였다. 대상 환자는 3주 간격으로 3차례의 IPL을 치료받았으며;치료 전과 3주 간격의 시간에 따른 Meibomian gland expressibility (MGE);Meibomian gland secretion score (MGS);눈물띠검사(TMH);비침습적 눈물막파괴시간(noninvasive break-time;NIBUT);플루오레신 각막염색 점수(Oxford scale);환자의 증상(Ocular Surface Diseases Index [OSDI];주관적인 증상 개선 정도)를 비교하였다. 결과: IPL 치료 후 마이봄샘 기능관련 지표(MGE;MGS);안구 표면 관련 지표(NIBUT;Oxford scale);안구건조 증상(OSDI score;주관적인 증상 개선 정도)은 치료 전과 비교하여 IPL 1차 후;IPL 3차 후 통계적으로 유의하게 개선되었다(모두 p<0.05). 하지만 눈물띠검사는 IPL 치료 전후 비교에서 통계적으로 유의한 변화를 보이지 않았다. 결론: 마이봄샘 기능부전을 가진 안구건조증 환자에게 IPL 치료는 눈물막을 안정시키고;마이봄샘 기능 이상 및 주관적인 증상을 개선시키므로 안구건조증의 효과적인 치료가 될 수 있음을 확인하였다. Purpose: To evaluate the therapeutic effect of intense pulsed light (IPL) therapy for the treatment of dry eye with meibomian gland dysfunction (MGD). Methods: A retrospective study was conducted for 124 eyes of 62 patients with dry eye with MGD who underwent 3 IPL sessions at 3 week intervals. All patients underwent clinical examination before and during treatment as well as 3 weeks after the last treatment. Measured parameters include Meibomian gland expressibility (MGE);Meibomian gland secretion (MGS) score;tear meniscus height (TMH);noninvasive break-time (NIBUT);corneal staining score (Oxford scale);Ocular Surface Diseases Index (OSDI);and subjective ocular discomfort improvement. Results: Meibomian gland function (MGE;MGS);ocular surface parameters (NIBUT;Oxford scale) and dry eye symptom (OSDI;subjective ocular discomfort improvement) of patients were significantly improved from baseline to after the 1st IPL;and the 3rd IPL weeks (p < 0.05 for all). However;no significant difference in TMH was observed. Conclusions: This study showed that IPL was a useful and effective treatment in patients of dry eye with MGD to stabilizes the tear film and improve meibomian gland function and ocular symptoms.

박창구(Chang-Goo Park),정준호(Jun-Ho Jeong),최준혁(Jun-Hyuk Choi),이지혜(Jihye Lee),정주연(Joo-Yun Jung),전소희(Sohee Jeon),이응숙(Eungsug Lee),최대근(Dae-Geun Choi) Korean Society for Precision Engineering 2019 한국정밀공학회지 Vol.36 No.11

The purpose of this study was to develop a selective patterning process with functional nanoparticles, using the selective hydrophobic treatment which can give surface energy differences. It is important to selectively pattern the nanoparticles in solution, to the desired site in a variety of fields such as transparent electrodes, displays, and bio-sensors. Selective hydrophobic treatment can reduce the additional post processes such as cleaning to remove particles unwanted position, which is a drawback of the existing solution process. Various patterns with sub-micron size that can’t be achieved with other solution processes could be fabricated by nanoimprint lithography, selective surface treatment, and a solution coating process. The transparent conductive electrode (TCE) using silver mesh patterns on the flexible substrate created from our study showed 24 Ω of sheet resistance and more than 82% transmittance. To verify the possibility of nano-patterning of various materials, quantum dot (QD) was also patterned by selectively filling. Selective surface treatment technology has significantly improved the filling process of nanoparticles into fine patterns less than 1 μm wide.

This article aims to provide auto-ethnography for self-growth and individuation through the experience of applying sandplay therapy to school counseling of 11 professional teacher-counselors and professional school counselors, changes in the counseling effect, and the counselors’ own sandplay therapy and dream symbol analysis. The auto-ethnographical research has mainly been about the experiences of one or two researcher(s)-participant(s), but in this study, 11 researchers-participants participated in the study to express and inform their common experiences in school counseling. The researcher-participants have experience of school counseling from 2 years and 5 months to 11 years and 5 months, and they are all female counselors. Research data include dreams and dream associations, sandplay pictures and association about sandplay pictures, related life events and experiences, contemplation, recollection, insights, observations of researchers/research participants, sharings by group SNS, individual interviews have been used. The four common themes are found: 1. dreaming of becoming school teacher-counselor/school counselor, 2. frustration: self-blame and resentment, 3. searching for breakthrough: finding identity, 4. accepting incompleteness, which is still in progress. Among them, searching for breakthrough: finding identity has two sub-themes: sandplay and dream: encounter with the inner world and wrestling with regrets for children.
