안기영 慶北大學校 醫科大學 1991 慶北醫大誌 Vol.32 No.3

Recently the incidence of pressure sores has been increased, due to the increased number of patients with injuries after traffic and industrial accidents or with long term loss of consciousness after various diseases. The patients have frequently required long term hospitalization and time-consuimg operation. According to these, the interest of plastic surgeon in pressure sore has increased and the techniques in the surgical management of pressure sores were also much improved. After World War Ⅱ, various methods for treatment of the pressure sore have been developed such as excision and direct closure, local rotational and transpotional flap, fasciocutaneous flap, myocuatenous flap, neurovascular island flap, microvascular surgery, or method by using tissue expanders, etc.. Author reviewed 16 patients who had received surgical treatment for pressure sore in the department of plastic surgery in Taegu Catholic Hospital from June 1990 to September 1991, and the following results were obtained; 1. On etiologic distribution, the spinal cord injuries due to traffic accidents was most common. 2. Locations of pressure sore were ordered in frequency as follows; Sacral area, 8 cases. Ischial area, 7 cases. Trochonteric are, 2 cases. Buttock, 1 case. 3. 16 patients were treated as follows; Exicison and direct closure, 2 cases. Local rotational and transpositional flap, 7 cases. Fasciocuataneous flap, 4 cases. Myocuatenous flap, 5 cases. The performed myocutaneous flaps were as follows: Bilateral gluteus maximus V-Y advancement(2 cases), Tensor fasuia lata myocutaneous flap(2 cases), Biceps and semitendinous V-Y advancement (1 case). 4. Post-op complications were found as follows; wound disruption, 4 cases, wound infection 3 cases, flap tip necrosis 1 case, secondary operation due to wound infection 1 case.

GTLC의 타입보존에 대한 기계증명

안기영 한국정보과학회 2019 정보과학회논문지 Vol.46 No.5

동적 언어에서 정적 타입 검사의 장점을 필요에 따라 부분적으로 활용하기 위한 목적으로 점진적 타이핑이 현업에서 쓰이는 언어(예: Python, JavaScript 등)에도 활발히 도입되는 추세이며 그에 따라 점진타입 타입 시스템의 이론적 토대에 대한 엄밀한 연구의 필요성도 높아지고 있다. 본 논문에서는 점진적 타이핑을 포함하는 타입 시스템 중 가장 기초가 되는 점진적 타입 시스템 GTLC의 타입 안전성 증명의 일부인 타입보존 성질을 Abella 증명도우미를 이용해 기계증명으로 유도한 내용을 보고한다. 또 그 기계증명 내용 중 일부를 구체적으로 살펴보며 관련 연구에서 같은 내용을 다른 증명도우미로 기계증명한 것과 비교해 Abella로 점진적 타입 시스템을 형식화하고 기계증명하는 데 어떤 장단점이 있는지 분석한다. Over the past decade, there has been a growing trend of supporting selective use of static typing in dynamic languages, coined "gradual typing", among the major real-world programming languages (e.g., Python, JavaScript), motivating studies on the theoretical basis for gradual typing. We developed mechanized proof for subject reduction, which is one of the two key parts of the type safety property of the gradually typed lambda calculus(GTLC), using the Abella proof assistant. We further elaborate on some parts of our mechanized proofs in order to highlight the pros and cons of using Abella for developing mechanized theories on gradual typing, compared to prior related work on GTLC using other proof assistants.

There are some difficulties in the reconstruction according to anatomic regions of the lower extremity such as thigh, knee, anterior tibia, heel and so on. The earlier the normal tissue saved and the necrotic tissue removed, the less the patients had complications and functional disability. There are many kinds of flap surgery in the reconstruction of the lower extremity such as local skin flap, local fasciocutaneous flap, local muscle flap and free flap. We have done 71 cases using the various flap operation excluding direct closure and skin graft among the patient of lower extremity injury from Jul. 1997 to Oct. 2002. Among 71 cases, 46 cases were due to traffic accidents and mechanical damages and 4 cases were burn, 5 cases were diabetic ulcer, 16 cases were cancer and other skin defects. Lower leg and foot were the most common lesion and the next was knee and thigh. And in the flap operations we have done, 32 cases(45%) were local skin flap, 18 cases(25%) were local fasciocutaneous flap, 6 cases(9%) were local muscle flap, 15 cases(21%) were free flap and so on. In early postoperative complications, the total flap necrosis was seen in 1 case, the partial necrosis in 6 cases, the infection in 5 cases and the hematoma or seruma in 3 cases. The bulky flap and ulceration were seen in 3 cases respectively and needed secondary operation after long term follow-up.The area below the knee joint is limited by its low vascularity, low tissue flexibility, high infectiousness and long periods of wound healing, and the reconstruction of the weight bearing heel needs proper skin thickness and durability. The better reconstruction of the lower extremity needs many experiences of various methods to us and we should know about their advantages and disadvantages.

Deliveries of tar, nicotine and carbon monoxide in mainstream smoke decreased with increment of exogenous potassium content of tobacco. Potassium malate was more effective than potassium nitrate, potassium carbonate, potassium citrate and potassium oxalate for the reduction of carbon monoxide, but potassium nitrate was more effective than potassium palate, potassium carbonat, potassium citrate and potassium oxalate for the reduction of carbon in the case of nicotine. Puff count and burning rate were slightly changed with added potassium salts.

Severe upper and lower extremity trauma may result in soft tissue loss with exposed bone and the subsequence of risk of chronic osteomyelitis or malunion of fracture fragments. Such injuries present a major reconstructive problem. But Since the introduction of microsugical technique, free muscle and myocutaneous flaps were employed to provide coverage of severely injured defects. Since Tai and Hasegawa(1974) first reported a breast reconstruction using by rectus abdominis myocuraneous flap, the free rectus myocutaneous flap has been widely employed for breast reconstuction, head and neck reconstruction, and extremity reconstruction in these days. The authors present their successful experience with free rectus abdominis muscle and rectus abdominis myocutaneous flaps for upper and low extremity reconstruction. From Nov. 94, to May 95, Five cases of severely injured extremites due to trauma or contact burn were treated with free rectus abdominis muscle flap or free rectus abdominis myocutaneous flap. All flaps except 1 case were survived without severe complications. As free muscle or myocutaneous flap, the free rectus abdominis flap has the advantages of a reliable pedicle, easy dissection, and an acceptable donor site, so it seems logical to apply the free rectus abdominis flap to apply in upper and lower extremity reconstruction.

Cigarette smoke is an aerosol consisted of both vapor and Particulate phases. In this study, the smoke condensates from several blended cigarettes were dissolved in water and the pH of the resulting solution was determined. The pH of the smoke condensate decreased with increase of puff number. In the beginning the pH decreased a little, while decreased remarkably from puff No.5 to puff No.10.
