Purpose: In the case of repair for far distal parts of FDP (Flexor digitorum profundus) division, the method of either pull-out suture or fixation of tendon to the distal phalanx is preferred. In this paper, the results of a modified loop suture technique used for the complete division of FDP from both zone 1a and distal parts of zone 1b in Moiemen classification are presented. Methods: From July 2006 to July 2009, the modified loop suture technique was used for the 10 cases of FDP in complete division from zone 1a and distal parts of zone 1b, especially where insertion sites were less than 1 cm apart from a tendon of a stump. In a suture technique, a loop is applied to each distal and proximal parts of tendon respectively. Core suture of 2-strand and epitendinous suture are done with PDS 4-0. Out of 10 patients, the study was done on 6 patients who were available for the followup. The average age of the patients was 49.1 years (in the range from 26 to 67). 5 males and 1 female patients were involved in this study. There were 3 cases with zone 1a and distal parts of zone 1b. The average distance to the distal tendon end was 0.6 cm. There were 5 cases underwent microsurgical repair where both artery and nerve divided. One case of only tendon displacement was presented. The dorsal protective splint was kept for 5 weeks on average. The results of the following tests were measured: active & passive range of motion, grip strength test, key pinch and pulp pinch test. Results: The follow-up period on average was 11 months, in the range from 2 to 20 months. There was no case of re-rupture, but tenolysis was performed in 1 cases. In all 6 cases, the average active range of motion of distal interphalangeal joint was 50.8 degree. The grip strength (ipsilateral/contralateral) was measured as 88.7% and the pulp pinch test was 79.2% as those of contralateral side. Flexion contracture was presented in 2 cases (15 degree on average) and there was no quadrigia effect found. Conclusion: Despite short length of tendon from the insertion site in FDS rupture in zone 1a and distal parts of zone 1b, sufficient functional recovery could be expected with the tendon to tendon repair using the modified loop suture technique.

긴급통신서비스 제공을 위한 SIP에서의 호 서비스 메커니즘에 관한 연구

이규철,이종협,Lee, Kyu-Chul,Lee, Jong-Hyup 한국정보통신학회 2007 한국정보통신학회논문지 Vol.11 No.2

IP(Internet Protocol) 기반 통신서비스가 발달함에 따라 인터넷 전화서비스가 기존 PSTN (Public Switched Telephone Network) 기반 전화서비스를 대체하는 서비스로 자리 잡아 갈 것으로 예상된다. 이를 위해 해결되어야 할 여러 가지 이슈 중 하나가 인터넷 전화서비스가 PSTN의 911과 같은 긴급전화서비스 제공 능력을 가지는 것이다. 미국의 경우에는 VoIP(Voice over Internet Protocol)를 사용하는 인터넷 전화에서도 PSTN의 전화서비스와 같이 911 서비스를 제공하도록 규정하고 있으며, 기본 VoIP 911 호 (Basic 911 또는 B-911)는 위치 정보 혹은 콜백 번호 없이 LEA(Law Enforcement Agency)의 일반 접근라인으로 라우팅 되고, 향상된 VoIP 911호 (Enhanced 911 또는 E-911)의 경우는 위치정보와 콜백 번호정보를 가지고 911 전용 네트워크상으로 라우팅 되어 지역 911 분배센터에 도착하도록 규정하고 있다. 그러나 현재의 VoIP기반 인터넷 전화망에서는 긴급전화서비스를 별도의 서비스로 다루고 있지 않거나 성능이 PSTN에 비해 크게 부족한 실정이며, 해당 호의 위치정보 및 콜백 번호정보 등이 파악되지 못해 가장 인접한 PSAP(Public Safety Answering Point)로 전달되지 못하는 문제가 있다. 본 논문에서는 이러한 문제점들을 해결하고 효율적인 긴급전화서비스를 제공할 수 있는 SIP(Session Initiation Protocol)기반의 긴급전화서비스 메커니즘을 제안하며, 실제 구현을 통하여 PSAP로의 효율적인 접근과 해당호의 정보를 정확히 알아낼 수 있음을 확인하였다. As the development of the various IP-based services, it is expected that Internet telephony service will gradually replace the traditional PSTN-based telephony service. But there are many issues resolved to spread the Internet telephony service. One of them is to support the emergency services in the Internet telephony. In the case of USA, it has been regulated that 911 services should be supported in the Internet telephony services using VoIP on the similar performance level to PSTN 911 service. According to the regulation, basic VoIP 911 calls should be routed to the general access line of LEA without the location information or the callback number, but the enhanced VoIP 911 calls with the location information and callback number should be routed on the dedicated 911 network and destined to the local 911 distribution center such as PSAP. But, in the current VoIP-based Internet telephony network, the emergency call service has not been handled as one of the special services as well at has a worse performance in comparison to it on PSTN. Moreover, the service has a critical problem that it can not be destined to the nearest PSAP because of the insufficient information about the location information and the call back number. In this paper, we suggest the SIP-based emergency call service mechanism in order to resolve the problems above mentioned. This suggested mechanism is implemented to show its effectiveness and efficiency.

천공 펀치 기계에 의한 수지 절단부의 재접합술

이규철,이동철,김진수,기세휘,노시영,양재원,Lee, Kyu-Cheol,Lee, Dong-Chul,Kim, Jin-Soo,Ki, Sae-Hwi,Roh, Si-Young,Yang, Jae-Won 대한미세수술학회 2010 Archives of reconstructive microsurgery Vol.19 No.1

Purpose: Industrial punch accidents involving fingers cause segmental injuries to tendons and neurovascular bundles. Although multiple-level segmental amputations are not replanted to regain function, most patients with an amputated finger want to undergo replantation for cosmetic as much as functional reason. The authors describe four cases of digital amputation by an industrial punch that involved the reinstatement of the amputated finger involving a joint and neurovascular bundle. Amputated segments were replanted to restore amputated surfaces and distal segments. Methods: A single institution retrospective review was performed. Inclusion criteria of punch injuries requiring replantation were applied to patients of all demographic background. Injury extent (size, tissue involvement), operative intervention, pre- and postoperative hand function were recorded. Result: Four cases of amputations were treated at our institute from 2004 to 2008 from industrial punch machine injury. Average patient age was 32.5 years (25~39 years) and there were three males and one female. Sizes of amputated segments ranged from $1.0{\times}1.0{\times}1.2\;cm^3$ to $3{\times}1.5{\times}1.6\;cm^3$. Tenorrhaphy was conducted after fixing fractured bone of the amputated segments with K-wire. Proximal and distal arteries and veins were repaired using the through & through method. The average follow-up period was thirteen months (2~26 months), and all replanted cases survived. Osteomyelitis occurred in one case, skin grafting after debridement was performed in two cases. Because joints were damaged in all four cases, active ranges of motion were much limited. However, a secondary tendon graft enhanced digit function in two cases. The two-point discrimination test showed normal values for both static and dynamic tests for three cases and 9 mm and 15 mm by dynamic and static testing, respectively, in one case. Conclusion: Though amputations from industrial punch machines are technically challenging to replant, our experience has shown it to be a valid therapy. In cases involving punch machine injury, if an amputated segment is available, the authors recommend that replantation be considered for preservation of finger length, joint mobility, and overall functional recovery of the hand.

이규철(Kyu Chul Lee),이성기(Sung-Ki Lee),김혜경(Hye Kyung Kim) 한국가금학회 2016 韓國家禽學會誌 Vol.43 No.2

본 연구는 4종의 재래닭인 연산오계, 현인흑계, 횡성약닭, 황봉의 무기성분, 비타민, 아미노산, 유리아미노산 및 핵산관련 물질 함량을 비교하기 위하여 실시하였고, 대조구로 백색 레그혼을 사용하였다. 시험용 닭은 품종별 3수씩 총 15수를 동일한 조건에서 53주간 사육하여 도계한 후 화학적 성분조사를 실시하였다. 재래닭의 Fe과 K 함량 특히 황봉 가슴육, 현인흑계 및 횡성약닭의 다리육이 백색레그혼에 비하여 높았고, Na 함량은 모든 부위에서 백색레그혼에 비하여 낮았다(p<0.05). 비타민 A 함량은 다리육에서 백색레그혼과 현인흑계가 높았고, 비타민 B1은 횡성약닭이 낮았으며, 비타민 B3는 가슴육의 경우는 4종의 재래닭이 백색레그혼에 비하여 높았고, 다리육은 횡성약닭이 백색레그혼에 비하여 높았다. 4종류의 재래닭 가슴육 총 아미노산 함량은 백색레그 혼에 비하여 재래닭 4종의 함량이 현저히 높았으며(p<0.05), 다리육은 유의적 차이가 없었다. 좋은 맛을 내는 아미노산 합계에 대한 좋지 않은 맛을 내는 아미노산 합계의 비율을 조사한 결과, 다리육의 비율이 가슴육에 비하여 모든 품종에서 높았다. 가슴육은 횡성약닭이 가장 높았고, 다리육은 현인흑계가 백색레그혼에 비하여 높았지만, 연산오계, 횡성약닭 및 황봉은 백색레그혼에 비하여 낮았다. IMP 함량은 현인흑계와 백색레그혼이 다른 품종에 비하여 가슴육과 다리육 모두에서 유의적으로 높았으며, AMP 함량은 가슴육과 다리육 모두에서 백색레그혼과 현인흑계가 다른 품종에 비하여 유의적으로 낮았다. GMP 함량은 황봉과 횡성약닭의 가슴육이 다른 품종에 비하여 유의적으로 높았고, 다리육의 경우는 백색레그혼, 황봉과 횡성약닭이 다른 품종에 비하여 높았다(p<0.05). 결론적으로 4종류의 재래닭이 백색레그혼에 비하여 무기질, 비타민 및 총 아미노산 함량이 우수하였고, 닭고기의 맛에 관여하는 유리아미노산 및 핵산관련 물질 함량도 품종별 차이는 있었지만, 백색레그혼에 비하여 재래닭이 우수함을 나타내고 있다. This study was conducted to compare nutritional composition and taste-related compounds of breast and thigh meats from four lines of Korean native chickens (KNC) Yeonsan Ogye, Hyunin Black, Hwangbong, and Hoengseong Yakdak. White Leghorn (WL) was used as a control. Fifteen male chickens (three chickens in each line) were grown under same condition and slaughtered at 53 weeks old. The contents of Fe and K in KNC, especially Hwangbong breast meat and thigh meat of Hyunin Black and Hoengseong Yakdak, were higher than WL. The contents of Na were lower in KNC compared with WL regardless of parts (p<0.05). Vitamin A contents were higher in thigh meat of WL and Hyunin Black, and vitamin B1 contents were lower in Hoengseong Yakdak than other lines. Vitamin B3 were higher in breast meat of four lines of KNC and thigh meat of Hoengseong Yakdak than WL. Total amino acid contents were higher in breast meat of KNC than WL. The level of good-tasting amino acids were significantly higher in breast meat of Hoengseong Yakdak and WL, and thigh meat of Hyunin Black and WL than other lines of chickens (p<0.05). The ratio of good-tasting amino acids to bitter tasting amino acids was higher in breast meat of Hoengseong Yakdak and thigh meat of Hyunin Black than WL. IMP contents were higher in Hyunin Black and WL than other lines of chickens. Based on these results, it can be concluded that four lines of KNC may have superior nutritional quality and taste when compared with WL.

연산군 대 조선은 변경 지역에 대한 여진 세력의 공격이 계속되자 다양한 대책을 논의했다. 조선은 군사 행동을 논의하는 동시에 관리를 파견해 여진 세력과 관계를 개선하고자 노력했다. 하지만 정벌을 당장 시행할 수 없는 상황이었고, 상대에 대한 정보도 부족했다. 조선조정에서는 귀화 야인 동청례를 건주 삼위 지역에 두 차례 파견하면서 추장들을 효유했고, 관련 정보를 수집했다. 이후 잠시 동안 양측의 관계는 개선된 것처럼 보였다. 이후 여진 세력은 조선의 변경 지역을 다시 공격하기 시작했다. 피해가 확대되는 속에서 조선 조정은 대외정벌을 결정했다. 하지만 당시 조선은 대외정벌을 시행할 수 있는 역량을 갖추지 못했다. 재정과 군액 등이 모두 부족했다. 대외정벌의 시행을 주장했던 국왕 연산군이나 대신들은 이를 실행할 수 있는 구체적 계획이 부족했다. 결국 연산군 대 추진되었던 대외정벌은 출병에 찬성했던 대신들까지 입장을 바꾸면서 정지되었다. 이 과정에서 조선 조정은 대외정벌의 시행방법에 대한 변화된 인식을 표출했다. 이는 15세기와 16세기의 조선이 가졌던 대외정벌 인식의 변화상을 보여주는 모습으로 평가할 수 있다. Yeonsan"gun"s Joseon discussed various countermeasures as the Jurchens continued to attack the region. Joseon discussed military action and dispatched officials to improve the Jurchens and relations. However, the situation was not able to enforce the punishment immediately, and there was a lack of information about the opponent. In Joseon, the chiefs of Dongcheongrye, a naturalized nightman, dispatched chiefs and collected relevant information. After a while, the relationship between the two sides seemed to improve. Afterwards, the Jurchens began to attack the territory of Joseon again. In the midst of the damage, Joseon decided on foreign conquest. At the time, however, Joseon did not have the capacity to enforce foreign conquest. Both financial and military shortages. There was a lack of specific plans to implement the Kings and substitutes who insisted on the implementation of foreign conquests. Eventually, the foreign conquest was suspended, changing positions even in favor of the troops. In the process, Joseon expressed a changed perception of how to implement foreign conquests. This can be assessed by showing the change of perception of foreign conquest of Joseon in the 15th and 16th centuries.

고려 말 조선 초 전쟁과 지도 만들기

Goryeo & Chosun Dynasty in the 15th century maintained their balance of diplomatic policy through ‘Foreign Conquest’. We have diculty in nding the case that the Korean Dynasty Country since the Middle Ages had militarily suppressed the peripheral powers like the 15th century. In particular, Chosun Dynasty always tried to nd its conduct cause of military expedition externally when enforcing ‘Foreign Conquest’. However, basically the conquest meant a military conduct for suppressing the external powers. In order to begin the ‘Foreign Conquest’, they had to plan taking various factors such as troops & supplies into consideration. e Conquest was very highly risky of facing with it when it proved to be a failure unlike other foreign policies. What’s more, the military movement toward the specic powers had the great possibility of causing the peripheral resistance. erefore, the ‘Foreign Conquest’ was not a policy to progress through short discussion & preparation at all. Chosun Dynasty’s foreign conquest during the 15th century was a policy which was greatly influenced by Goryeo Dynasty. The time when the foreign conquest policy used to reveal its true feature was from the era of King GongMin at the end of Goryeo Dynasty. erefore, it can be explained that the foreign conquest of Chosun Dynasty was the representative foreign policy in the 15th century and was evidently inuenced by that of the end of Goryeo Dynasty. Of course, the wars fought by Goryeo & Chosun Dynasty were aiming for its own benets. At that time, ‘its own benets’ which Goryeo & Chosun Dynasty tried to obtained, were essentially related to the problems of area & territory. e conquest of Goryeo & Chosun Dynasty shared with the goal for the purpose of extending the external inuence abilities & securing a new area & territory.

서울 노원구 역사문화자원의 특성과 지역학 연구

이규철 ( Lee Kyu-chul ) 콘텐츠문화학회 2023 콘텐츠문화연구 Vol.6 No.-

노원구는 서울에서 새로운 구역으로 확정된 기간이 30여 년 정도에 불과한 신생 지역이다. 그렇기 때문에 노원구 지역의 역사나 관련 활동에 관한 기록이 다른 지역에 비해 적을 수밖에 없다. 하지만 노원구의 구성원들을 중심으로 지역 내 역사 유적과 역사 인물을 발굴하고 소개하는 작업이 지속적으로 진행되어 왔다. 이와 함께 지역의 역사문화 자원을 찾아 개발하는 작업도 계속 시도되었고 일정한 성과를 도출할 수 있었다. 노원구는 지리적 특성과 아직은 오래되지 않은 역사를 가지고 있다. 따라서 노원구 지역과 관련된 역사 소재나 기록 등이 충분히 확보되지 못했다. 그렇다면 장기적으로는 지역의 역사문화자원을 확보하는 동시에 다양한 역사콘텐츠로 개발하기 위한 방법들에 대한 구성원 모두의 고민이 필요하다. 역사문화자원에 관한 소재를 확보하면서 역사콘덴츠로 개발하는 등의 새로운 활용 방안을 찾기 위해서는 크게 두 가지 방안에 대한 준비가 필요하다. 지역 관련 자료의 보존과 관리를 위한 데이터베이스(DB) 구축과 인접 지역 연계를 통한 보다 다양한 방식 의 역사문화자원 관련 프로그램의 개발이다. 이와 같은 작업들이 진행된다면 새로운 성과들을 기 반으로 노원구와 관련된 다양한 지역문화콘텐츠를 생산하는 작업 에도 많은 도움이 될 것이라 기대한다. Nowon-gu is a new area in Seoul that has only been designated as a new district for about 30 years. Therefore, there are inevitably fewer records of Nowon-gu's history or related activities compared to other regions. However, local members continued to discover and introduce Nowon-gu's historical relics and figures, as well as discover and develop historical and cultural resources, and achieved certain results. Due to Nowon-gu's geographical characteristics and short history, historical materials and records related to the region are limited. If so, there is a need to consider new ways to secure and develop historical and cultural resources in the future. In order to find new ways to utilize historical and cultural resources, it is necessary to develop more diverse programs related to historical and cultural resources by establishing a database for the preservation and management of related materials and linking adjacent regions. If these tasks are possible, they could help produce various local cultural contents based on new achievements.
