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.

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.

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.
FMCW 거리-도플러 이미지 중첩을 통한 CNN 기반 드론 탐지 및 식별

FMCW 레이더의 거리-도플러 이미지의 드론별 미세 도플러 특징이 거리가 멀어질수록 희미해지는 문제를 해결하기 위해서 거리-도플러 이미지 중첩 방법을 제안하였다. 중첩 이미지를 이용하여 Alexnet 전이학습 기반 분류기를 이용하여 3 종의 드론에 대한 식별 시험을 시행한 결과 상당한 식별 성능 향상을 관찰할 수 있었다.
일반논문 : “ -지 않-” 의 축약과 융합 형태 “ -잖-” 의 특성 연구

The purpose of this research is to study the characteristics of the contraction form “ -ci anh-” and the fusion form “ -canh-” , as well as reveal the diverse usages and characteristics of these, in order to further advance synchronic Korean language research. “ -canh-” and the combined forms of final endings are used widely in spoken language. “ -canh-” which has been contracted from “ -ci anh-” , has been diversely grammaticized and is within the grammaticalization process. “ -canh-” is used as the contracted form of “ -ci anh-” but it has also become a fusion form that has new meaning and usage. “ -canh-” is explained after being divided into “ -canh1-” , “ -canh2-” , “ -canh3-” , depending on the form and grammatical characteristics. “ -canh1-” is a derivative suffix that creates a psychological adjective that shows the negative perception of the speaker. “ -canh2-” , which is a contracted form of “ -ci anh-” , is a negative contraction that functions to negative contraction or is used in a rhetorical statement as confirmation. “ -Canh3-” no longer functions as a negation but is used in a declarative statement and functions to give confirmation.
