강동희,신상욱,백승완 대한마취과학회 1997 Korean Journal of Anesthesiology Vol.33 No.5

Background: Total intravenous anesthesia with propofol can cause respiratory depression and apnea especially during induction of anesthesia. To study the possibility of reversal of respiratory depression during anesthesia with propofol, pretreated with nabuphine or not, the respiratory effects of doxapram to spontaneously ventilating patients were investigated. Methods: Patients were divided into 4 groups - saline-propofol-saline group(SPS), saline-propofol- doxapram group(SPD), nalbuphine-propofol-saline group(NPS), and nalbuphine-propofol-doxapram group (NPD). After saline or nalbuphine pretreatment, anesthesia was induced with propofol and then doxapram or saline was intravenously injected. Apneic time interval, blood pressure, heart rate, respiratory rate, minute ventilation, end tidal CO2 partial pressure and oxygen saturation were measured in every minutes during induction of anesthesia. Percent changes of each values were compared. Results: There is no differences in apneic time intervals in each groups. The percent change of first minute ventilation in SPD group after doxapram injection unchanged significantly compared with those depressions of SPS, NPS and NPD group(p<0.05). Respiratory rates increased in SPD and SPS groups after laryngeal mask insertion. There is no differences in minute ventilation, respiratory rate and end-tidal CO2 concentration between nalbuphine pretreated groups regardless of doxapram injection. Conclusions: Doxapram has effect in increasing minute ventilation after propofol induction within first few minutes, but it cannot reverse respiratory depression during propofol induction pretreated with nalbuphine.

부분 광배근 피판을 이용한 안면마비의 단단계 재건

강동희 대한성형외과학회 2005 Archives of Plastic Surgery Vol.32 No.3

The goal in facial paralysis treatment is to achieve the normal appearance of the face as well as to reconstruct the natural symmetrical smile. In cases of facial paralysis, a widely accepted procedure is the two stage method, which combines neurovascular free muscle transfer with cross face nerve grafting. Although the results are promising, the two operations of this method, which are about 1 year apart, impose an economic burden on the patients and require a lengthy period before results are obtained. In order to overcome these drawbacks, one stage method, using latissimus dorsi neurovascuular free muscle flap was introduced. Between January 2000 and January 2004, fifteen patients with long standing facial paralysis were treated in the Korea University Anam Hospital. The segmental latissimus dorsi with long nerve and pedicle was transferred to the paralyzed side of the face. The first postoperative movement of the transferred muscle was reported at 8.9 months, faster than that of the two stage method. During the next 24 months, a constant increase in the power of muscle contraction was observed. The fifteen cases were evaluated within an average of 31.7 months following the surgery and satisfactory results including muscle contraction were obtained in eleven of the cases but muscle contraction was not found in three cases.

Purpose: The most accepted method for the reanimation of a paralyzed face is the two-stage method that combines cross-face nerve grafting with free-muscle transfer. Although the results of reconstruction with this method are satisfactory, there is an excessive delay between the stages, which prolongs the period of rehabilitation. In order to overcome this drawback, a one- stage, neurovascular free-flap reconstruction method using free neurovascular muscle flaps is introduced. Methods: From 1994 to 2004, 35 patients with longstanding facial palsy were treated. Fifteen patients underwent the single-stage reconstruction with the latissimus dorsi muscle, and 20 patients underwent the two-stage reconstruction method with the gracilis muscle. We compared the long-term results of the two methods of reconstruction. The mean follow-up period was 28.7 months for one-stage reconstruction, and 35.2 months for the two-stage, respectively.Results: In the patient group of the single stage reconstruction, both mouth corner excursion and animation grade were markedly improved at the final postoperative visit. Moreover, the first muscle contraction occurred earlier in this group, than in the two-stage reconstruction group. However, four patients in the single stage group never achieved a first muscle contraction or mouth corner excursion.Conclusion: Facial palsy is a very challenging condition for cosmetic surgeons to deal with. Traditional methods for treatment of chronic facial palsy use a two- stage muscle flap which is time-consuming and burdensome to patients, many of whom are averse to waiting 8 to 12 months to complete the two stages. The one- stage reconstruction method described herein uses a latissimus dorsi free-flap and has demonstrated consistent positive outcomes in clinical assessments.

Surgical Management of a Mandible Subcondylar Fracture

강동희 대한성형외과학회 2012 Archives of Plastic Surgery Vol.39 No.4

Open reduction and anatomic reduction can create better function for the temporomandibular joint, compared with closed treatment in mandible fracture surgery. Therefore, the double miniplate fixation technique via mini-retromandibular incision was used in order to make the most stable fixation when performing subcondylar fracture surgery. Those approaches provide good visualization of the subcondyle from the posterior edge of the ramus, allow the surgeon to work perpendicularly to the fracture, and enable direct fracture management. Understanding the biomechanical load in the fixation of subcondylar fractures is also necessary in order to optimize fixation methods. Therefore, we measured the biomechanical loads of four different plate fixation techniques in the experimental model regarding mandibular subcondylar fractures. It was found that the loads measured in the two-plate fixation group with one dynamic compression plate (DCP) and one adaption plate showed the highest deformation and failure loads among the four fixation groups. The loads measured in the one DCP plate fixation group showed higher deformation and failure loads than the loads measured in the two adaption plate fixation group. Therefore, we conclude that the selection of the high profile plate (DCP) is also important in order to create a stable load in the subcondylar fracture.

IoT 환경에서의 네트워크 보안 프로토콜 성능 분석

강동희,임재덕 한국정보보호학회 2022 정보보호학회논문지 Vol.32 No.5

The Internet of Things (IoT), combined with various technologies, is rapidly becoming an integral part of our daily life. While it is rapidly taking root in society, security considerations are relatively insufficient, making it a major target for cyber attacks. Since all devices in the IoT environment are connected to the Internet and are closely used in daily life, the damage caused by cyber attacks is also serious. Therefore, encryption communication using a network security protocol must be considered for a service in a more secure IoT environment. A representative network security protocol includes TLS (Transport Layer Protocol) defined by the IETF. This paper analyzes the performance measurement results for TLS version 1.2 and version 1.3 in an IoT device open platform environment to predict the load of TLS, a representative network security protocol, in IoT devices with limited resource characteristics. In addition, by analyzing the performance of each major cryptographic algorithm in version 1.3, we intend to present a standard for setting appropriate network security protocol properties according to IoT device specifications. 사물인터넷(Internet of Things, IoT)은 다양한 기술과 결합하여 일상생활의 전반으로 빠르게 자리 잡았다. 빠른 속도로 사회 전반에 자리 잡은 데 반해 보안에 대한 고려는 상대적으로 미흡하여 사이버 공격의 주요 대상이 되고 있다. IoT 환경의 모든 기기는 인터넷에 연결되어 일상생활과 밀접하게 활용되고 있기에 사이버 공격으로 인한 피해도 심각하다. 따라서 보다 안전한 IoT 환경에서의 서비스를 위해 네트워크 보안 프로토콜을 이용한 암호화 통신이 반드시 고려되어야 한다. 대표적인 네트워크 보안 프로토콜에는 IETF에서 정의한 TLS(Transport Layer Protocol)가 있다. 본 논문은 제한된 자원 특성을 갖는 IoT 기기에서 대표적인 네트워크 보안 프로토콜인 TLS의 부하를 예측하기 위하여 IoT 기기 오픈 플랫폼 환경에서 TLS 버전 1.2와 버전 1.3에 대한 성능 측정 결과를 분석한다. 또한 버전 1.3에서 지원하는 주요 암호화 알고리즘의 성능을 분석하여 IoT 기기 사양에 따라 적합한 네트워크 보안 프로토콜 속성을 설정할 수 있는 기준을 제시하고자 한다.

Purpose: Advanced carcinoma of the tongue is a devastating disease which may cause severe speech or swallowing dysfunction. But, none to date has provided all of the complex functions of the tongue. The purpose of this study is to review our experiences with individuals who underwent glossectomy followed by reconstruction using free tissue transfer. Methods: Between February 1998 and February 2005, twenty-four patients underwent glossectomy followed by free tissue transfer reconstruction. The defects of tongue caused by partial or subtotal glossectomy were reconstructed by means of radial forearm or lateral thigh free flap with nerve innervation. Especially for the patients who underwent total glossectomy, we reconstructed deglutition muscles anatomically with nerve reinnervation, a procedure that allows the grafted muscle to maintain good tongue bulk without obvious atrophy.Results: Patients were reviewed to determine their functional outcome as it related to speech, deglutition, and aspiration. All patients achieved oral intake of a soft diet and acceptable speech. Conclusion: Although reconstruction following glossectomy using free tissue transfer is not ideal, this procedure is safe and reliable, and provides predictable results. A future challenge is the development of a surgical procedure for reconstruction of a tongue that maintains mobility and sensation using neurotized flaps.
