Purpose: To evaluate the results of half-dose photodynamic therapy (PDT) and determine the correlation between morphological changes measured by spectral-domain optical coherence tomography (SD-OCT) and visual acuity in patients with chronic central serous chorioretinopathy (CSC). Methods: Twenty-five eyes of 25 patients with chronic CSC who had received half-dose verteporfin PDT were enrolled in the present study. The best-corrected visual acuity (BCVA), outer nuclear layer (ONL) thickness, and the integrity of the photoreceptor inner and outer segment junction (IS/OS) using SD-OCT were evaluated at baseline and at 3 and 6 months after treatment. Results: The neurosensory retinal detachment disappeared in all eyes 6 months after treatment. The BCVA improved significantly from 0.50 ± 0.32 to 0.31 ± 0.29 log MAR at 6 months (p < 0.001). The average ONL thickness at the central fovea was 88.76 ± 19.95 μm at 6 months and the ONL thickness was well correlated with the BCVA (γ = -0.64; p = 0.001). There was no significant correlation between the status of IS/OS and the BCVA. Conclusions: Half-dose PDT is effective in treating chronic CSC resulting in visual improvement and complete resolution of neurosensory retinal detachment. The ONL thickness which was positively correlated with the BCVA could be an indicator for visual prognosis of chronic CSC. J Korean Ophthalmol Soc 2013;54(11):1715-1722

In the domestic housing market, uncompleted lot-solid apartments and unoccupied residences are increasing in the medium-large scale area whose rents and transactions have been unstable, as going through the financial crisis and economical recession. Demands for small-scale housings are steadily increasing by practical consumer group who don't need large places, which are often not needed for the current people who are spending most of their time outside of their houses. Therefore, this study proposes the useful methods for spatial planning for small-scale houses for multiple households, including variable form, levels form, multi-level form, and smart-sizing. For efficient spatial planning for that purpose, here, small-scale housings are not limited to places for families with 1-2 members, but considered as one of broader approaches to graft various households and families. In addition, we examined the existed trends of researches about spatial utility of small-scale places, and did the research about the status of small-scale housing developments, and then proposed the direction for future small-scale housings by analyzing the advanced examples.

Purpose: We present a case of a patient with optic neuritis who had underlying suspicious idiopathic thrombocytopenic purpura.Case summary: A 35-year-old female with no other systemic disease visited our clinic due to acutely decreased visual acuity in her left eye 10 days in duration. Relative afferent pupillary defect was observed, but without definite papilledema. Based on brain magnetic resonance imaging (MRI), optic neuritis was suspected. Laboratory tests showed increased red blood cells, hemoglobin and, hematocrit levels and decreased platelets. Peripheral blood smear test showed decreased platelets, relative lymphocytosis and atypical lymphocytes. Specific antibodies for autoimmune disease were not present. High-dose steroid pulse therapy (methyl prednisolone 1.0 g/d, 3 days) was started. One month after treatment her visual acuity and platelet count recovered and her visual field defect improved.

This study aims to investigate the intonational realization of sentences including the two types of intransitive verbs. It has been accepted that intransitive verbs fall into two subclasses-unergative verbs and unaccusative verbs, each associated with a particular argument structure. The unergative-unaccusative dichotomy has also been linked to differences in the phonetic constructions in which they appear. Previous linguistic analyses claim that the placement of pitch accents is determined by the verb-argument structure of the intransitive sentences in a broad focus context. To challenge this claim, we replicated Hoskins` experimental samples and further tested with new phonetically and semantically controlled sentences. We recorded speech of native speakers of English and Korean learners of English and performed prosodic and acoustic analyses. Our results showed that, when the argument structure was controlled, English native speakers produced similar intonation patterns to previous studies. Meanwhile, when the sentences were both semantically and phonetically matched, the patterns were contrary to the previous studies. Therefore, the argument structure approach is insufficient for the explanation of accentuation of intransitive sentences in broad contexts. (Changwon National University)

The rapid growth of economy improves not only the life quality of people in this modern society but also standards of value in connection with how those people would spend money as they engage in various leisure and cultural activities. That being the case, hotels are currently changing into places of new concepts depending on those new lifestyles of these people, and in those new places, people can entertain and experience as enjoying cultures. The marketing collaboration of the hotels with brands can be used as a more inclusive way to enhance brand images. In addition, as having infinite possibilities of the collaboration`s being able to create a new-concept space with an identity of a brand included, this collaboration makes it possible for the design hotels to decorate their interior spaces differently from those of other hotels. In the light of that the brand collaboration is basically divided into three groups which are the fashion collaboration, the technique collaboration and the designer collaboration, and the brand collaboration is also able to express the interior spaces of the design hotels as working on those six components, such as reproduction, events, alteration, messages, culture and image. After all, through the brand collaboration marketing, this thesis expects an interior design of a new-concept design hotel which would play a role as a complex cultural space.

박시윤(Park, SiYoon) 글로벌지식융합학회 2020 지식융합연구 Vol.3 No.1

본 연구는 ADHD 요인 중 하나인 결핍된 가정환경으로 인하여 정서불안과 주의력결핍으로 학교생활에 어려움을 겪고 있는 초등학교 아동을 대상으로 하여 만다라 매체를 통한 미술회화 체험을 통해 정서불안 및 주의력 향상에 미치는 효과에 대해 검증하고 이를 특정한 아동을 대상으로 적용하여 그 결과에 대해 분석하고 평가하였다. 이 연구를 통해 아동 스스로가 본인의 잘못 된 행동을 알게 되었으며, 스스로 변화하려고 노력하는 모습을 보이고 있으며, 가정과 학교에서 서로 협조를 통해 아동의 일에 공유하고 노력하고 있는 한편, 아동 스스로 비행 행동을 자제하고, 스스로 판단할 수 있는 능력과 아동의 자존감이 커져가고 있음을 알 수 있다. 프로그램 적용을 통해 확인된 바와 같이 본 연구를 통해 만다라 매체를 통한 미술회화 중심의 체험이 ADHD 아동의 정서불안과 주의력 결핍과 과잉행동 장애에 실질적인 효과가 드러났다는 점에서 아동에게 긍정적인 영향을 미친 것으로 평가된다. 향후 이와 직·간접적으로 연관된 연구가 앞으로 수행될 ADHD 아동의 정서불안과 주의력결핍 및 과잉행동장애에 대한 후속연구에 이바지하길 기대한다 This study is aimed at elementary school children who have difficulty in school life due to emotional anxiety and attention deficit due to the deficient family environment, one of the factors of ADHD, and their effect on emotional anxiety and attention through art painting experience through Mandala media Was verified and applied to specific children, and the results were analyzed and evaluated. Through this study, the children themselves became aware of their own wrongdoings, showing that they are trying to change themselves, sharing and making efforts in children’s work through cooperation at home and school, and refraining from self-delinquency behavior. It can be seen that the ability to judge themselves and the child s self-esteem is growing. As confirmed through the application of the program, this study showed that the experience centered on art painting through the Mandala medium had a positive effect on children in that it had a practical effect on the emotional anxiety, attention deficit and hyperactivity disorder of ADHD children. Is evaluated. In the future, it is hoped that studies directly or indirectly related to this will contribute to the follow-up studies on emotional anxiety, attention deficit and hyperactivity disorder in ADHD children to be conducted in the future.

목적: 다래끼 수술 도중 리도카인 국소마취제 주입 시 의도치 않게 발생한 각막 천차로 인해 생긴 데스메막분리 및 각막 부종에 대해 전방 내 14% C3F8 가스 및 공기 주입술 시행으로 데스메막분리가 유착된 1예를 보고하고자 한다. 증례요약: 8세 여자 환아에서 다래끼제거술을 위한 국소마취를 위해 상안검에 리도카인 주사를 주입하던 중 강한 통증과 급격한 시력 저하를 호소하여 술기를 중단하고 본원으로 전원되었다. 세극등 소견상 각막의 찰과상 및 전반적인 각막의 부종으로 인해 각막의 세부구조가 잘 관찰되지 않았으나 각막단층촬영 검사상 데스메막분리가 관찰되었다. 초진 후 3일째 각막 상피는 완전히 재생되었으나 이후 3주까지 데스메막의 박리가 계속되어 다시 시행한 각막단층촬영 검사상 일부 데스메막 파열이 관찰되어 적극적인 치료를 위해 전방내 가스 및 공기 주입술을 시행하였다. 48시간 만에 데스메막 파열이 발생하였던 부분이 말려 있는 것을 제외하고는 전체적인 유착을 얻었으며 이후 약 3개월간 경과관찰 후 안정적인 각막소견과 정상시력을 회복하였다. 결론: 안검의 마취주사 중 예상치 못한 각막천자로 발생한 데스메막분리 및 파열은 각막부종으로 인한 시력저하를 초래하였고 일반적인 데스메막분리와 달리 시간의 경과에 따른 회복을 가져오지 못했다. 이에 적극적인 치료방법으로 선택한 전방내 14% C3F8 가스주입술 및 공기주입술을 통해 데스메막분리가 유착되었으며, 정상 시력을 회복한 증례를 경험하였기에 이를 보고하고자 한다. <대한안과학회지 2016;57(11):1790-1794> Purpose: To report a case of Descemet’s membrane detachment and corneal edema caused by an iatrogenic corneal perforation created while performing a local anesthetic (lidocaine) injection into the eyelid for a hordeolum incision and a drainage procedure. The detachment resolved after 14% C3F8 gas and air injections into the anterior chamber. Case summary: An 8-year-old female visited our clinic after the onset of severe pain and decreased visual acuity while receiving a local anesthetic injection into the upper eyelid in preparation for a hordeolum incision and drainage procedure. Corneal optical coherence tomography (OCT) showed Descemet’s membrane detachment. Three days after the first visit, the corneal epithelium had entirely healed. However, Descemet’s membrane detachment persisted even after three weeks of follow-up. A corneal OCT was repeated after three weeks and showed a partial Descemet’s membrane rupture. A more aggressive treatment method was deemed necessary, and gas and air injections into the anterior chamber were performed. After 48 hours, aside from some Descemet’s membrane rolling at the site of rupture, overall reattachment of Descemet’s membrane was noted. After three months of follow-up, the patient showed a stable corneal state and normalized vision. Conclusions: Descemet’s membrane detachment and rupture resulting from an iatrogenic corneal perforation during an injection of lidocaine to the eyelid led to decreased visual acuity from corneal edema. As a more aggressive treatment method, 14 % C3F8 gas and air injections into the anterior chamber were performed and resulted in near complete reattachment of Descemet’s membrane’s and normalization of the patient’s visual acuity.
