Purpose: To assess the accuracy of estimating postoperative deviation in large-angle exotropia over 40 prism diopters (PD). Methods: A retrospective analysis was performed on 61 exotropia patients with over 40 PD exotropia who had undergone 2-muscle surgery by two surgeons and with at least 6 months follow-up. The accuracy was assessed by analyzing the discrepancy between preoperatively predicted residual deviation and deviation at postoperative 6weeks. Successful surgery was defined as deviation within ± 10 PD at the last postoperative visit. Results: More accurate residual deviation was predicted in exotropia with prism diopters between 40 and 59 (97.8%) than in exotropia with 60 PD or more (62.5%). And there was no significant difference between two surgeons. Surgical success rates at six months and one year after surgery were 96.8%, 94.7% in exotropia with 40 to 49 PD, 71.4%, 60.0%, 50 to 59 PD, 50.0%, 45.5%, 60 PD or more, respectively. There were four patients of whom the postoperative deviation angle exceeded more than 10 PD of the estimated deviation. Conclusions: The accuracy of estimating residual deviation prior to surgery was higher and more successful surgery was achieved in exotropia ranging in 40 to 59 PD than in exotropia with 60 PD or more. Therefore, 2- muscle surgery will be suitable for large-angle exotropia with less than 60 PD. J Korean Ophthalmol Soc 2010;51(12):1614-1619

Purposes: The purpose is to establish the direction of healthcare R&D through private nonprofit organization. Methodology: The data is divided into two groups: 12 physicians and pharmacists, and 16 persons including professors related to university donation, non-profit foundation executives. Each group was subjected to two Delphi surveys. To analyze the validity of the opinion, the content validity ratio and the consensus of experts were verified. Findings: Funding should be invested in 'development research' and 'application research'. The factors that hinder the donation culture are 'donation prevention system such as tax imposition system and rebate double penalty system', 'insufficient motivation of fund raising person', and 'lack of fund specializing specialist'. The fund raising strategy should be centered on a small number of large donors or a balance between large and small donors. The fund raising target should be effective to raise funds for corporate and individual donors. It is necessary to clarify the purpose of the social problem to be solved by the campaign strategy for promoting donation, to announce the validity of the trust and transparency of the institution, and to emphasize the social investment by the private sector. Practical Implications: It is necessary to present directions through private nonprofit organizations for the future development of healthcare R&D. The legal and institutional deficiencies of the domestic nonprofit organization fundraising infrastructure should be improved. In order to create a social investment climate, it is necessary to improve the awareness of donations and develop various donation programs for the private sector.

이병희,유형식,이종두,정진일,박창윤,이종태,Lee, Byung-Hee,Yoo, Hyung-Sik,Lee, Jong-Doo,Chung, Jin-Ill,Park, Chang-Yun,Lee, Jong-Tae The Korea Society of Nuclear Medicine 1994 핵의학 분자영상 Vol.28 No.1

This study was aimed to compare the density of the functional microcirculation of hepatocellular carcinoma (HCC) with normal liver and to investigate the effect of hepatic-arterial oily chemoembolization (HAE) by radionuclide examination. Methods : Eight patients with HCC proven by biopsy in five, and clinically and radiologically in three were included. The mixture of 2 cc normal saline with three to four mCi of $^{99m}Tc$-MAA was infused through a hepatic-arterial catheter for a minute. Dynamic images were obtained at a rate of 4 sec per frame for a minute, and static images and SPECT were followed. Results : In three patients who underwent hepatic arterial angiography (HAA) alone, radioactivity was markedly increased in tumors compared to the adjacent liver immediately after infusion of $^{99m}Tc$-MAA. The ratios of tumoral and extratumoral up-take (T/E ratio) were above 6.5 (range; $6.5{\sim}l9$, mean; 12.5). In four of the five patients who under-went superselective HAE, T/E ratio were remark-ably decreased ($0.5{\sim}1.3$). The areas of embolization were better delineated in radionuclide study than in postembolization HAA. In the other one who was considered to be embolized completely on HAA, strong radiouptake in the tumor was disclosed (T/E ratio; 7.0). Conclusions : Therefore hepatic-arterial flow study with radionuclide imaging using $^{99m}Tc$-MAA can be a valuable method to assess the accurate embolization effect in HCC. 본 저자들은 $^{99m}Tc$-MAA를 이용하여 정상 간조직에 대한 간암의 상대적인 미세 혈류량을 조사하고 간암 환자에서 간동맥 색전술을 시행 후 상대적인 혈류량의 변화를 검사함으로써 간동맥 색전술의 효과를 알아보고자 하였다. 여덟명의 간암 환자들을 대상으로 하였는데, 이 중 다섯 명은 조직 생검으로, 그리고 나머지 세 명은 임상적, 그리고 방사선학적으로 진단되었다. 3내지 4mCi의 $^{99m}Tc$-MAA를 2cc의 생리식염수에 혼합하여 간동맥내에 위치된 카테터(catheter)를 통하여 1분간에 걸쳐 서서히 주입한 후 바로 동적영상을 4초 간격으로 1분 동안 얻었으며, 이어서 정적 영상과 SPECT를 시행하였다. 간동맥 혈관 조영술만을 시행한 세명의 환자에서 $^{99m}Tc$-MAA를 주입하자마자 주변 간 조직에서 비해 간암내에 강한 방사능 섭취를 보였으며, 주변 간조직에 대한 간암의 방사능 섭취율은 6.5 이상이었고, 그 범위는 6.5에서 19였으며 평균은 12.5였다. 간동맥 색전술을 시행한 5명 중 4명에서 주변 간조직에 대한 간암의 방사능 섭취율이 심하게 감소하였다($0.5{\sim}1.3$). 또한 색전된 부위는 색전술 후 시행한 추적 간동맥 혈관 촬영상에서 보다 동위원소 검사에서 잘 관찰되었다. 간동맥혈관 촬영상에서 완전히 색전된 것으로 생각된 한 환자에서 동위원소 검사상 간암에 강한 방사능 섭취를 보였다(주변 간조직에 대한 간암의 방사능 섭취율 7.0). 따라서 본 저자들은 $^{99m}Tc$-MAA를 이용한 간 동맥 혈류 검사는 간암에서 색전술의 효과를 정확히 평가할 수 있는 유용한 검사법으로 이용될 수 있으리라 생각한다.

Purpose: To evaluate two surgical methods-amniotic membrane transplantation (AMT) and split-conjunctival grafts (SCG)-for double-head pterygium, with regard to the postoperative outcome and recurrence rate. Methods: In a total of 16 eyes (14 patients), 7 eyes (6 patients) receiving amniotic membrane transplantation and 9 eyes (8 patients) receiving split-conjunctival grafts were compared to evaluate recurrence and complications. Results: Within the amniotic membrane transplantation group, two eyes (29%) had corneal recurrence, and 3 eyes (43%) had conjunctival recurrence. The mean follow-up period was 21.9±3.5 months, and all recurrences were on the nasal side. The average period preceding the corneal recurrences was 7.2±1.8 months. Within the split-conjunctival grafts group, the mean follow- up was 13.6±2.1 months, and neither the corneal nor conjunctival recurrences were observed. In addition, the eyes of this group were more aesthetically stable, with only one eye exhibiting pseudo-pterygium at the donor site. Conclusions: In cases of double-head pterygium without contraindication of conjunctival autograft, the split-conjunctival grafts produced fewer recurrences and showed enhanced cosmetic results, as compared to the amniotic membrane transplantation, indicating that the split-conjunctival grafts is the superior choice over amniotic membrane transplantation.

Purpose: To compare the bleb morphology and surgical outcomes of a limbus-based group with those of a fornix-based group who underwent trabeculectomy with mitomycin C (MMC). Methods: Sixty-five eyes of 59 patients who had undergone trabeculectomy with MMC and who were observed for one year or more were included in the present study. A limbus-based conjunctival flap was used for 34 eyes of 31 patients and a fornix-based conjunctival flap for the other 31 eyes of 28 patients. The bleb morphologies were classified and compared after one year or more postoperatively according to the Moorfield Bleb Grading System, and intraocular pressure and success rates were evaluated. Results: The central bleb vascularity of the limbus-based group was statistically significantly lower than that of the fornix- based group (1.79 ± 0.64; 2.16 ± 0.73, p = 0.042). The risk of cystic bleb formation was higher in the limbus-based group (38.2%; 16.5%, p = 0.047). There were no differences in the IOP or success rate between the two groups. Conclusions: There were no differences between the two groups with regard to the IOP or cumulative success rate. However, in the fornix-based group, the central bleb vascularity was lower and the risk of avascular cystic bleb formation was higher than those in the limbus-based group.

조찬휘ㆍ이병희ㆍ이용운(Chan Hui ChoㆍByong hi LeeㆍYong Woon Lee) 유기성자원학회 2016 유기물자원화 Vol.24 No.1

본 연구에서는 침출수 재순환 시스템을 적용한 중온 혐기성소화를 이용하여 음식물류 폐기물을 분해하여 메탄가스를 생산하였다. 실험은 36℃로 유지되는 항온수조 내에 생물반응조와 침출수 저장조로 구성된 2개의 동일한 시스템(System A, System B)을 사용하였고, 생물반응조 하단 30 mm위에는 스크린이 있어 고액분리를 하여 침출수 저장조로 침출수를 이송하였다. 침출수 재순환은 매일 수행하였으며, 침출수 재순환 시에는 생물반응조 하단에서 침출수 저장조로 2.5 L를 30분간 이송한 뒤 다시 침출수 저장조에서 생물반응조 상부로 2.5 L를 30분간 주입하였다. 주입된 음식물류 폐기물은 수집되기 전 한 번 세척하였으며 반응조에 주입되기 전에 36℃로 온도를 올렸다. System A에 49.1 g VS, System B에 54.0 g VS을 2주 간격으로 투입하였다. 저해인자로 측정된 항목은 NH₄⁺-N과 염도였으며, 두 가지 항목의 농도 모두 시스템에 끼친 영향은 없는 것으로 나타났다. System A는 112일간, System B는 140일 동안 운전하였는데, 각 시스템에서 인발된 슬러지는 없었다. 음식물류 폐기물의 혐기성 소화를 통한 평균 메탄 발생량은 System A의 경우 0.439 L CH4/g VS, System B의 경우 0.368 L CH4/g VS로 나타났다. In this study, mesophilic anaerobic digestion of source separated food waste was carried out by leachate recirculation system and methane gas was produced. Two systems - system A and B were fabricated and placed within water bath to maintain 36℃. Each system was comprised of an anaerobic bioreactor and a leachate tank. Leachate in bioreactor was separated through the screen located at 30 mm above the bottom and a pump was installed to transfer collected leachate to the leachate tank. Everyday, 2.5 L of the leachate was pumped from the bioreactor to the leachate tank for 30 min and transferred leachate was pumped back to the top of the bioreactor for 30min, sequentially. Source separated food waste used for this experiment was washed by water before transferring to the laboratory. Transferred food waste was warmed to 36℃ before being fed to bioreactors. System A was fed to 49.1 g VS (Volatile Solids) and System B was fed to 54.0 g VS at every two weeks, respectively. NH₄⁺-N and salinity were monitored to see the inhibition toward anaerobic bioreaction and it was found that concentrations of these materials were not high enough to affect the bioreaction. Although the food waste was fed biweekly for 112 days and 140 days at system A and B, respectively, there was no sludge withdrawal from each system. Average methane productions rates were 0.439 L CH4/g VS and 0.368 L CH4/g VS for system A and B, respectively.
