Purpose: Various kinds of local flap or free flap have been used for coverage for soft tissue defects with bone exposure over the ankle and dorsum of foot. Adipofascial flaps, nourished by vascular plexuses of the subcutaneous tissue and deep fascia originating from the local perforators of the major vessels, appear particularly to be indicated for the reconstruction of these areas. Our experience with this flap on the dorsum of foot and ankle has also been quite encouraging. Methods: The design of the flap is determined by the size and the location of the defect. The base of the flap is chosen depending on the availability of the soft tissue around the defect. The ratio of the area of the flap to the area of the base wound be more reliable to predict the survival of the turnover flap by the conventional length-to-width ratio. Nineteen patients with defect over the dorsum of the foot and ankle were resurfaced with adipofascial turn-over flaps and skin graft. Results: The average age of the patients was 38.2 years(3 - 81 years). The flap size was from $2{\times}3cm$ to $8{\times}5cm$. The average follow-up time was 6 months. All flaps survived completely except one case who suffered distal necrosis of the flap. The additional skin graft was required for partial skin loss in the five cases. Other functional impairment was not noted. Conclusion: Dissection of the local adipofascial turnover flap is quite easy, quick, requires less time and sacrifice of surrounding muscle itself, and maintains major arteries. In most cases, donor-site morbidity is minimal with an acceptable scar, and both functional and esthetical results were satisfactory. Therefore, Adipofascial flap could be an option for the difficult wounds around the foot and ankle.

Because of accelerated urbanization public body visiting nursing project that started according as matter of health on urban class in the lower brackets of income was concentrated on Social interests has a unsatisfied points to propel project efficiently from the lack of rating materials. Therefore centering around written contents in documentary literature of citizen health by household in five years from starting year of project to now. visiting frequency by medical manpower was evaluated quantitatively and qualitatively in aspect of management hereupon. for the sake of giving a basic materials for public health project of this field. This research presents documentary literature of citizen health which become materials is that as one person's charged region of nurse in duty scale. district is Kang-Buck Gu. the object is resident in the lower brackets of income grounded livelihood protection law and who is admitted by the head of organ~chief of health care). and the number of material centering around the head of a household is 415 copy. The result of research is summarized. as follow. 1. Average visiting frequency examinated by medical manpower show difference according to valuables of supervision characteristics namely average visiting. Frequency of nurse has long term residence in case registration season is early and supervision season is the first year and is high incase a kind of house is unlicdnsed mountain town. Average visiting frequency with doctor is high incase supervision season is the first year and the medical insurance system is admitted by chief of health care. That shows that a man of discomfort behavior left alone are yet many in local society. The meaning of this result shows that the continuity of official relation about class in the lowest brackets of income of long term residence goes well between househole who is a user of visiting nursing service of the object according to midway income under management influences a given duty of nurse s and so causes quantitative decrease. 2. In case behavier and condition of health that nurse diagnoses are bad. as the type matter is a lack of health and the number of patient is large. the average visiting frequency of nurse is high. because average visiting frequency with doctor is high as the condition of health is bad and the number of patient is large. That is similar with that of nurse. CD Average visiting frequency of nurse s seen by matter of disease is very high only in apoplexy by 39.50 and is confined within limits from 7.63 to 11.36 in other disease. But average visiting frequency with doctor is double as many as that of nurse but defined in apoplexy hypertension and articulate. (1) Average visiting frequency of nurse by existence in inoculation of hepatitis is low by 6.73 in unidentified group and very high by 26.89 in group of non-inoculation and the case of the antigenic positive man of B type hepatitis or epileptic who can't be inoculated shows 13.00 and that even family nursing service is needed to them. That result shows that though one person nurse of local charge has a large scale of duty. as visting nursing service is given a class who has a large demand preferentially by respectively accurate nursing diagnosis. the number of diagnosis service is similar with it. 3. During five years. average visiting frequency of nurse is 10.84 and average visiting frequency with doctor is 76.50 seeing from the official scale of nurse. visiting by household is performed two more per year to the average. Seeing this by type of service. average visiting frequency of nurse is higher in indirectly nursing than in directly nursing and that suggests that at the time of visiting household nurse performs education of protection lively save patient but at the time of contrastedly visiting with doctor. directly nursing is more contents of service show no difference by man power and medication dressing by demand is 14.3 and 18.6 the aid of hardship term of doctor and nurse is high by 18.7 and 17.00 in the request of hospitalization when seeing by demands. 4. Action by turns exemplified 1994 is well in sequence of 2/4 turn. 3/4 turn. 1/4 turn. 4/4 turn. When seen by average visiting frequency of nurse but gradually is even. Without difference by turns. average visiting frequency of doctor is much higher in 1/4 turn than other turns. Type of service by turns is all even but directly nursing is inactive in 4/4 and indirectly nursing. Very increases in 4/4 and so. Nurse's quantity of duty is plentiful that shows that by evaluation of last turn and plan of project. Contents of service follows that medication and dressing is the highest by' 5.57 in 1/4turn. goes down gradually by turn. becomes 3.57 in 3/4 turn. and increases again by 4.83 in 4/4 turn. the rest service is higher in 2/4 turn than other turns. 5. Total visiting frequency of nurse is explained to total $37.5\%$ by six valuables of visiting frequency of doctor. nursing demand. demand of diagnosis. condition of behavior. year. Special terms and magnitude of influential power is the same as sequence of enumerated valuables. Namely. the higher the visiting frequency of doctor. the bigger nursing and demand of diagnosis is. the worse the condition of behavior is. the older the object is and the more the household of special terms is. the high total visiting frequency of nurse is.

Background: Losing balance during locomotive actions becomes an increasing threat to both the community-dwelling elderly and elderly with Parkinson disease (PD). Those with PD may be at a high risk of fall due to particular characteristics during the turn. Turning around during locomotive actions may be one of problematic factors causing losing balance. Objects: This study is part of a larger study, which in part aims to identify turning strategies, to compare the strategies in the elderly with and without idiopathic PD aged 51 years and older and to distinguish whether the turning strategies can predict the elderly at risk of falls. Methods: A total of 22 community-dwelling elderlies (10 elderlies with idiopathic PD and 12 healthy elderlies) were investigated for the turning strategies during the timed up and go test. Results: There were some significant differences between the two groups during turning (p<.05). The idiopathic PD group had a tendency of challenging on taking more number of steps, more time to accomplish and staggering more for the turn relative to the control group. Conclusion: Taking more number of steps and more time to turn may be useful for distinguishing the characteristics of PD from that of the healthy elderly in turning strategy.

The purpose of this paper is to design and implement the user motion pattern control system for the simulated vehicle. After analyzing the user motion patterns in the system, the patterns are used to control the moving direction of the simulated vehicle such as forward, backward, turn right, turn left etc. The patterns in the system around are sent to the simulated vehicle in real time. In order to execute the suggested user motion pattern control system, the Kinect is used for executing the system. The Kinect recognizes the specified user motion patterns and it transmits the data to the user motion pattern control system. There are nine kinds of the user motion patterns in the system for controlling the simulated vehicle. In addition to this, some sensors are used to detect the condition of the simulated vehicle. GPS is also used to estimate the current location of the simulated vehicle and to obtain the driving information.

A carbon nanotube field emission display(CNT FED) panel with a 2 inch diagonal size was fabricated using a screen printing of a prepared photo-sensitive CNT paste and vacuum in-line sealing technology. After a surface treatment of the patterned CNT, only the carbon nanotube tips are uniformly exposed on the surface. The diameter of the exposed CNTs are usually about 20 nm. Using the photo-sensitive CNT paste, we have developed a triode type CNT FEA with a self-aligned gate-emitter structure. The turn on voltage was around 100 V which corresponds to according the turn on field of about $40V/{\mu}m$. By the creation of a self-aligned gate-emitter structure, it is expected that the screen printed photo-sensitive CNT paste is promising as a good candidate for the large size field emission display.

In the response to increasing the demands for electrical energy, much effort aimed to develop and commercialize HTS power equipments have been made around the world. Among them HTS transformer is one of very Promising one. For the development, the cryogenic insulation technology should be established. In this paper V-t characteristics of turn insulator, Kpaton, among insulation components of HTS transformer was discussed with Weibull distribution and n-value. V-t tests of Kapton were conducted using Cu tape electrodes shaped HTS tape depending on wrapping number. The n-values of 2 and 3 times wrapped tape are 27.54 and 30.58. Although breakdown strength of the 3 times one is higher than the 2 times the 3 times one have more weak points with overlapping so it have higher probability of incidental accidents.

오늘날 지능형 영상 검지기 시스템(Intelligent Vehicle Detection System)이 추구하는 방향은 기존 시스템의 교통 소통 정보 습득을 넘어서 교통정체, 사고 등과 같은 부정적인 요인을 줄이는 것이다. 본 논문에서는 도로 교통법규 위반 상황 중에서 가장 치명적인 사고를 유발 할 수 있는 불법 유턴 차량을 검지하는 알고리즘을 제안한다. 영상의 옵티컬 플로우 벡터(Optical Flow Vector)를 구하고 이 벡터가 불법 유턴 경로 상에 나타난다면 불법 유턴차량에 의해 생긴 벡터일 확률이 높을 것이라는 점에 착안하여 연구를 진행했다. 옵티컬 플로우 벡터를 구하기 전에 연산량 절감을 위하여 코너(corner)와 같은 특징점을 선지정한 후 그 점들에 대해서만 추적하는 피라미드 루카스-카나데(pyramid Lucas-Kanade) 알고리즘을 사용했다. 이 알고리즘은 연산량이 매우 높기 때문에 먼저 컬러 정보와 진보된 확률적 허프 변환(progressive probabilistic hough transform)으로 중앙선을 검출하고 그 주위 영역에만 적용시켰다. 그리고 검출된 벡터들 중 불법 유턴 경로위의 벡터들을 선별하고 이 벡터들이 불법 유턴 차량에 의해 생긴 벡터들인지 확인하기 위해 신뢰도를 검증하여 불법 유턴 차량을 검지하였다. 최종적으로 알고리즘의 성능을 평가하기 위해 알고리즘별 처리시간을 측정하였으며 본 논문에서 제안한 알고리즘이 효율적임을 증명하였다.
