Purpose: To recognize the anatomical positions of the superior oblique muscle in enucleated eyes using trypan blue. Methods: Twenty-two surgically-enucleated eyes of 11 bodies were studied. The shortest distance from the nasal insertion of superior rectus to the anterior end of the superior oblique tendon, the distance from the temporal insertion of superior rectus to the anterior end of the superior oblique insertion, and the greatest width of superior oblique tendon insertion were measured by caliper 3 consecutive times. The average values in each of the above 3 points were calculated, and values prior to and after trypan blue staining were compared. Results: Prior to staining with trypan blue, the average distance from the nasal insertion of superior rectus to the anterior end of the superior oblique tendon was 4.97 mm and the average distance from the temporal insertion of superior rectus to the anterior end of the superior oblique insertion was 7.57 mm; after staining with trypan blue, the average values were 5.09 mm and 7.65 mm, respectively. There was no statistically meaningful difference in values prior to and after staining (p > 0.05). Prior to staining, the average value of the greatest width of the superior oblique tendon was 10.32 mm, and after staining with trypan blue, the average value increased to 10.76 mm. There was a statistically meaningful difference between the values (p = 0.02). Conclusions: Trypan blue staining helped to recognize the location and the width of the superior oblique tendon more precisely. J Korean Ophthalmol Soc 2012;53(10):1488-1492

上代日本詩が, 八, 七, 六母音說という, 樣樣な說が出され, 學界では未だ論爭がくりかえされている, それで, 筆者は, より根源的な問題をとりあげて考察し, 問題の究明をはかろうと計劃し, まず, 「キ(ギ)甲乙」の用字法について再檢討してみたのであるが, その方法論として, これらの漢字の上古漠語の音價を調べ, それと同時に, 上古漢語から切韻までの中國語音韻史の變化をたどってみた. 一方, 近世朝鮮朝の諸文獻に載せられてある漠字音の反映された內容と, また, 古代韓國語の i 母音と關連される諸樣相を硏究した諸論文を參考する等, 以上のような考察の結果をまとめて, 日本上代語の「キ(ギ)甲乙の音價を推定してみた. その結果として,「キ(ギ)甲乙」の母音音價は, 各各 i と i であると推定した.

Purpose: The purpose of this study was to evaluate the great saphenous vein (GSV) as a conduit for crossover femoro-femoral bypass. Generally the conduit for crossover femoro-femoral bypass is a synthetic material because of the acceptable long-term patency and low complication rates. But, as the average life expectancy becomes extended, a better patency rate becomes more important. In this study, we compared the patency rates and hemodynamic results between crossover femoro-femoral bypass operations with GSVs and those with synthetic grafts. Methods: From 1998 to 2008, 119 femoro-femoral bypass operations were done. Among them, 38femoro-femoral bypass used GSV as a conduit (group I) and 79 operations used expanded polytetrafluoroethylene (group II). Two cases used arm veins and we excluded those cases. Results: The 3 year primary patency rate of total cases was 75.1%, 93.7% in group I and 66.1% in group II. There were no statistical differences in hemodynamic results such as peak systolic velocity, volume flow and ankle/brachial systolic pressure index between the two groups. Conclusion: The 3 year primary patency rate of group I was better than that of group II. However there were no differences in hemodynamic changes. So GSV is recommended as a conduit for crossover femoro-femoral bypass especially in young patients who are eager to have longer patency rates after surgery instead of less invasive endovascular therapy.

DRM은 온라인 음악, 동영상, e-book 등 디지털 형태의 콘텐츠가 증가하면서 불법 복제가 쉬워짐에 따라 저작권자의 권리가 침해되는 것을 방지하기 위한 목적으로 생긴 기술이다. 아날로그 유통구조와는 다른 디지털 콘텐츠 유통 시장에서 콘텐츠 및 지적 재산권을 보호하고 이용자에게 새로운구매 서비스를 제공함으로써 소유에서 사용 권리로의 이동을 가능하게 하였다. DRM의 필요성이 커짐에 따라 저작권자는 DRM과 같은 기술적 보호 조치를 엄격히 요구하고 있다. 현재의 DRM 방식이 사용 용이성은 떨어지지만 이용자 또한 저작권의 보호와 콘텐츠의 올바른 이용에는 대부분 저작권자와 의견을 같이 한다. 콘텐츠 제공업체는 DRM을 이용하여 다양한 서비스를 설계하고 서로 다른 가격을 줌으로써 이용자들에게 서로 다른 권리를 제공할 수 있다. 이에 이용자들은 기호에 따라 보다 더 다양한 방법으로 차별성을 가진 콘텐츠를 구매할 수 있다. 앞으로 이용자의 디지털 콘텐츠 수요는 지속적으로 증가할 것으로 보이며 DRM의 중요성도 더욱더 커질 것이다. Due to the increase in digital contents such as on-line music service, videos and e-books, illegal copy has became easier so that DRM(Digital Rights Management) is designed to prevent infringement of copyright. It protects contents and copyright and provides new purchase service to users in the digital content market so that transferring from possession to rights to use has become possible. As need of DRM has been increased, rights holders require technical protection measures such as DRM. However DRM is inconvenient to use, users and rights holders have the same opinion about the right use of contents. Contents providers provide users with different types of rights by designing various services and prices. So users are able to purchase differential contents to the taste by more various ways. Since demand on digital contents is expected to be increased steadily, DRM will become more and more important.
