`Purpose: We present a case of choroidal osteoma and report a pattern of optical coherence tomography and multifocal electroretinography with a literature review. Case summary: Using B-scan and CT, we performed OCT and MF-ERG in a patient diagnosed with choroidal osteoma. OCT revealed serous retinal detachment in the macula and a thick, irregular plate-like structure with high reflectivity in the choroidal mass lesion. MF-ERG demonstrated that Trace arrays show suppression of central and peripheral signals, especially in central lesions. Ring averages show reduced amplitudes in all locations, and 3D-topography of the response density shows marked suppression of the central signal and no foveal peak in comparison with the unaffected left eye. Conclusions: In patients with choroidal osteoma, OCT can reveal thick plate-like high reflectivity with an irregular outer surface, and MF-ERG can predict retinal dysfunction. `

`Purpose: We evaluated the effect of amniotic membrane transplantation with fibrin glue after redundant conjunctival resection. Methods: After enchelon-shaped resection of inferior redundant conjunctiva, an amniotic membrane was transplanted using fibrin glue in symptomatic conjunctivochalasis. Conjunctiva was fixed to the episclera with 10-0 nylon. Results: The subjects were 18 eyes of 9 patients (two males=4 eyes, seven females=14 eyes) with an average age of 67.9±7.7 years (range: 54-79 years). Mean operation time was 35.6±5.6 minutes/eye (range: 30-45 minutes/eye) and mean numbers of sutures were 8±0.76 (range: 7-9). The mean follow-up period was 10.4±3 months (range: 6-14 months) and the mean time to full epithelization was 14.5±3.4 days (range: 11-20 days). At postoperative days 1-2, the lower tear meniscus was reconstructed. There were no recurrences or any postoperative complications observed. Conclusions: Amniotic membrane transplantation after redundant conjunctival resection in conjunctivochalasis resulted in reconstruction of the lower tear meniscus with stable conjunctival surface and marked improvement of subjective symptoms. Operation time and early postoperative irritation symptoms could be reduced with the use of fibrin glue.`

본 연구에서는 최근 국가⋅사회적 이슈가 되고 있는 방역 R&D와 관련하여, KIST가 10여 년간 수행해온 과제들의 성과를 추적하고 가치를 분석하였다. 이를 위해, 기존 출연연 연구성과에 대한 단기결과(output) 중심의 분석을 보완하는 장기적인 성과(outcome)와 효과(impact)를 고려하는 다면적 R&D 가치평가 모델을 수립하고, 출연연의 주요 연구성과를 논문 수, 기술이전료 등의 정량성과만으로 판단하는 협소한 시각을 벗어나 경제⋅사회적 파급효과를 함께 발굴하고 측정하였다. 또한 방법론적으로도 기존의 연구 결과를 종합하여, 편익접근법, 피해비용접근법, 산업연관분석 등을 다양하게 사용하여 무형의 연구성과를 발굴하고 정량화하였다. 분석결과, KIST가 수행한 방역 R&D 과제의 Input(연구개발비 총 217.1억원) 대비 Output, Outcome 및 Impact(2,376억원)은 10.9배로 나타났다. 특히 KIST의 방역 R&D 성과항목의 파급효과 중 95.3%(2,265억원)를 감염병으로 인한 사회적 비용절감액이 차지하여, 방역 R&D의 성격이 과학기술적 성과 및 산업계 대형기술 현안 해결보다는 국가⋅사회적 파급효과가 두드러진 것으로 해석되었다. 이러한 연구결과가 향후 출연연 연구성과의 중장기적 효과를 더 발굴하고 구체화하기 위한 논의의 기폭제가 되기를 기대한다. In this study, in relation to quarantine R&D, which has recently become a national and social issue, the performance of the tasks KIST has been carrying out for the past 10 years was tracked and the value was analyzed. To this end, we established a multi-faceted R&D valuation model that considers long-term outcomes and impacts that complement short-term, output-oriented analysis of existing research outcomes, and the economic and social ripple effects were discovered and measured together, beyond the narrow view of judging the major research achievements of the research institute based solely on quantitative results such as the number of papers and technology transfer fees. In addition, methodologically, by synthesizing existing research results, intangible research results were discovered and quantified using various methods such as benefit approach, damage cost approach, and input-output model. As the result, the output, outcome, and impact (208.73 billion won) compared to the input (total R&D expenditure of 21.71 billion won) of the quarantine R&D task performed by KIST was 9.62 times. In particular, 94% (197.04 billion won) of the ripple effect of KISTs quarantine R&D performance items was occupied by saving social cost due to infectious diseases, so the nature of quarantine R&D was interpreted to have a more pronounced national and social ripple effect than scientific and technological achievements and resolution of large-scale industrial technology issues. These research results will serve as a catalyst for discussions to further discover and materialize the mid- to long-term effects of the research results of research institutes in the future.

Purpose: Subjective auditory perceptual assessment by the trained clinician’s ear are known as the gold standard for assessment of voice impairment. However is no consensus among experts on terminology in Korea. The purpose of this study was to conduct a preliminary study to develop the standardized guideline for terminology that is necessary to describe auditory perception qualitatively and quantitatively in voice disorders of Korea. Methods: At first, a subjective questionnaire for the Korean translation and definition of 25 auditory perceptual assessment terms proposed by Titze was answered by six speech-language pathologists. In second, a new questionnaire that was reconstructed with objective items based on the responses to the first questionnaire was completed by 14 experts who have experience on voice disorder for more than 10years in Korea. In both questionnaires, the necessity of 32 auditory perceptual assessment terms that were selected among the 25 terms by Titze, GRBAS and CAPE-V was surveyed. Results: The consensus on Korean translation of auditory perceptual assessment terms was moderate (52.6%) between exerts. The terms ‘rough’ and ‘shimmer’ demonstrated highest consensus of 85.7%. The consensus on Korean definition of auditory perceptual assessment terms was also moderate (61.6%). The term ‘yawny’ showed complete consensus (100%). The necessity of auditory perceptual assessment terms vaired with terms, but the consensus on the necessity was high. Conclusions: It is necessary to develop and apply various standardized vocabulary terms for clinical evaluation that can express pathology and physiological characteristics during vocalization. In addition, despite the fact that there are a lot of auditory-perceptual terms, there is a lack of knowledge about voice quality terms, suggesting the need to promote and educate the developed voice quality terms.

Clinical data about vocal nodules have seldom been reported, even though vocal nodules are commonly diagnosed in outpatient speech and voice clinic. This study aims to investigate clinical characteristics of the patients who are diagnosed with vocal nodules. This study analyzed the data for 10 years from the 319 patients diagnosed with vocal nodules (45 males and 274 females with the mean age of 39.4 ranging from 2 to 83) in terms of gender, age, occupation, voice change initiation pattern, change with time, throat clearing, smoking history, type of voice abuse, acoustic analysis, maximum phonation time, GRBAS, and VHI. Thirteen patients (4.08%) had unilateral vocal nodule and 306 patients (95.9%) had bilateral vocal nodule, the majority of which had a pattern of asymmetry (73.9%). The glottal closure pattern was hourglass in 72.1% of patients, posterior chink in 17.9% of patients, and irregular in 7.9% of patients. The most common occupational category was professional voice users (43.4%). The voice abuse pattern included excessive talking in 96 patients (76.8%), loud voice in 78 (62.4%) patients, and excessive singing in 17 patients (21.6%). The patients showed worse scores in G, B, and S than in R and A for the GRBAS evaluation. The most recommended treatment for vocal nodules was voice therapy. The current clinical data will be helpful for treatment planning for the patients of vocal nodule.

The purpose of this study is to explore the nature of game theory analyzing the 2010 World Exposition process. In particular, two- level games in the game theory is applied to this study. Prisoner`s dilemma has been used to analyze the negotiation process for attracting the 2010 World Expo, in which Yeosu, Korea participated. Assumingly, Russia and Korea would take a style of distributive negotiation, which is focusing on zero-sum game, while Mexico and Korea would take a style of integrative negotiation, which is focusing on positive sum game. To defeat the mainland China, which was the final winner in the 2010 World Expo, Korea should have taken advantage of the game theory strategies to make Russia and Mexico be supporters of Korea. The study suggested that the future negotiation for attracting mega events like the World Expo should be analyzed in terms of relationships among structure, strategy, process and outcomes using the nature of game theory.
