Purpose: In the process of replantation of the amputated fingertips, the primary concern was given to survival of the amputees, while the functional aspect of digits after the surgery has been easily neglected. Although an internal fixation with a K-wire is often a part of replantation of the amputated fingertips, little consideration had been given to the study of relationship between distal interphalangeal joint fixation and post operative range of motion. A comparative study in relation to post operative range of motion was done on two different groups, one group with K-wire insertion and the other group without a K-wire insertion at the distal interphalangeal joint. Materials and Methods: The study was done on the cases of a single digit amputation conducted at our institute (the age in the range of 10 to 60) in about four-year of time span from March of 2005 to March of 2009. The cases with a thumb replantation, osteomyelitis or articular surface injury have been excluded from this study. The cases of both head and shaft fracture, except the insertion site of tendon, of distal phalanx of internal fixation with a single K-wire were reviewed for this study. A group of 24 cases without distal interphalangeal joint fixation in comparison to a group of 22 cases with distal interphalangeal joint fixation was reviewed to assess the postoperative range of motion at distal interphalangeal joint on the 6th week after the surgery. And, on the 30th month after the surgery, a group of 10 cases without distal interphalangeal joint fixation in comparison to a group of 10 cases with joint fixation was reviewed. A K-wire was removed in about 5 weeks after the fracture was reunited under the radiographic image, immediately followed by a physical therapy. Result: The active range of motion for a group without interphalangeal joint fixation was measured $49.0^{\circ}$ on average, while $28.6^{\circ}$ was measured for a group with interphalengeal fixation on the 6th week after the surgery. On the 30th month after the surgery, the active range of motion was measured $52.0^{\circ}$ and $55.0^{\circ}$ on average for a group without and with interphalangeal fixation respectively. Conclusion: In the process of replantation of the amputated fingertips, short-term(on the 6th week) improvement of postoperative active motion of range can be expected in the cases without distal interphalangeal fixation in comparison to the cases of interphalangeal joint fixation with a K-wire. However, there seems to be no difference on motion of range in a long-term (on the 30th month) follow up period.
한승규,Han, Seung-Gyu 사단법인 한국당뇨협회 2007 당뇨 Vol.213 No.-
당뇨병 합병증 중의 하나인 당뇨발을 일으키는 원인에는 여러 가지 요인이 복합적으로 관련된다. 이들 요인 중 특히 조심해야 할 사항이 세 가지 있는데 말초혈관이상, 세균감염, 신발 등에 의해 발에 가해지는 과도한 압력이다. 세균감염이나 부적절한 신발착용, 보행에 의한 발부위의 압력증가는 적절한 치료와 주의를 통해 충분히 극복 될 수 있는 문제지만 말초혈관병변은 사실 불가항력적인 면이 있기 때문에 가장 치료가 어려운 부분이다. 따라서 당뇨발 환자의 말초혈관질환에 대해 서술하고자 한다.

Background: rhGM-CSF has been shown to enhance the migration and proliferation of endothelial cells and to promote keratinocyte growth. This study was tried to evaluate the effect of rhGM-CSF dressing on the uninfected wounds. Methods: Thirty Sprague-dawley white mice(250-300g) were selected in this study. The number of wound with the diameter of 5 mm, was 3 in left and 3 in right at the symmetric sites, respectively. The site of rhGM-CSF dressing was decided by a randomization. rhGM-CSF($Leucogen^{(R)}$) was diluted in the distilled water($5{\mu}g/mL$). The experimental wound group was dressed by l mL of distilled water mixed with rhGM-CSF and control wound group was dressed by l mL of distilled water. The dressing was done, every 24 hours. The criteria of comparison were the duration of wound healing duration, histologic findings and the bacterial culture of wound sites. Results: The duration of wound healing was $10.3{\pm}1.7days$ in experimental group and $10.2{\pm}2.8days$ in control group, without significant difference. There was no specific difference of histologic findings between both groups. The pathogen was not found, at all. Conclusion: It seems to be that rhGM-CSF has no prominent effect on the uninfected wound healing in the mice without immune suppression.
침입 탐지 로그 데이터에서의 슬라이딩 윈도우 집계함수에 관한 연구
한승규(Seung Gyu Han),이원석(Won Suk Lee) 한국컴퓨터정보학회 2007 한국컴퓨터정보학회 학술발표논문집 Vol.15 No.2
최근 들어 데이터 스트림에서의 슬라이딩 윈도우 집계함수 처리에 대한 연구가 널리 진행되고 있다. 데이터 스트림이란 빠른 속도로 무한히 생성되는 데이터 집합을 말하며 이러한 데이터를 처리하는데 있어서 가장 중요한 점은 한정된 메모리 공간 내에서 처리가 되야 한다는 점과 실시간에 처리가 가능해야 한다는 점이다. 그렇기 때문에 위와 같은 조건들을 만족시키며 집계 함수 처리를 하는 것은 어려운 문제이다. 따라서 본 논문은 기존의 연구되어온 슬라이딩 윈도우 집계함수 처리 방법들을 소개하고, 실제 데이터베이스를 이용해 집계함수 처리를 하여 정확도를 산출하고 이를 통해 성능을 비교하여, 향후 슬라이딩 윈도우 집계함수의 연구방향을 제시하고자 한다.

본 저자는 출생 후 정상 발달을 보였고 경련의 과거력이 없었던 3세 환아에서, 임상적으로 약 24시간 동안 의식의 혼탁을 보여 시행한 뇌파 소견상 국소적인 극서파가 지속적으로 관찰되어 복합부분 발작 중첩증으로 진단한 증례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Nonconvulsive status epilepticus, which constitutes about 25% of all cases of status, has been subdivided into generalized nonconvulsine(absence) status and complex partial status. We report a case of complex partial status epilepticus in a 3-year-old male patient with altered mental function lasting about 24 hours. The electroencephalographic finding was compatible with complex partial status and the outcome of treatment is excellent, so far.

The main purpose of this research is to inscribe problems of the description of language of North Korean in Korean dictionaries. There are a few dictionaries that explain the language of North Korean. Therefore this research examined descriptions of language of North Korean in the Korean dictionaries Focusing on Pyojlln-Gugeo-Daesajeon. Language of North Korean is considered as one of part of registers: use district. Taking a view of the macro-structure of dictionary description, The entry of The Language of North Korean in Pyojun-Gugeo-Daesajeon was refered to The entry of Jo-Seon-Mal-Daesajeon. Therefore there are some errors that the words chosen as Language of North Korean though they are used in South Korea. Even in the micro-structural aspect, it can be seen that North Korean is described systematically different from South Korean in both explanation and sample sentences of an entry. Hence, in order for South Korean dictionary to have a consistent description of entry words, the description system of North Korean in Pyojlln-Gligeo-Daesajeon should be modified. Furthermore, taking the reality to consider North Korean dictionary into account, the description system for North Korean entry words in other dictionaries should consider these matters. Finally, this research suggest synthetic structure of dictionaries in order to improve descriptions of dictionary.

Objectives Agent Orange is a defoliant chemical that is widely known for its use by the U.S. military during the Vietnam War. It is known to be associated with the occurrence of various diseases in exposed subjects. However, few previous studies have focused on the effects of exposure to Agent Orange on cognitive dysfunction. Methods A total of 387 male subjects participated in the study. They were divided into those who were exposed to Agent Orange (n=301) and those without exposure (n=86). Both were evaluated with neuropsychological batteries, including the Consortium to Establish a Registry for Alzheimer’s Disease and the Seoul Neuropsychological Screening Battery-Second Edition. Results The group exposed to Agent Orange showed significantly higher scores in the Rey Complex Figure Test copy and recognition compared to those without exposure. Conclusion In this study, we compared the effects of exposure to Agent Orange on cognitive function in groups that had not yet progressed to dementia. The Agent Orange exposure group showed better results in some tests evaluating visuospatial and memory function.
