In this study, we selected ten normal women in their 20's and 4 weeks measured Exercise Intensity, Voluntary Ventilation, Respiratory Exchange Ratio, Oxygen and Calorie Consumption and Ventilation Equivalent of them during Normal Gait, Splint-equipped Gait and Crutch Gait With Splint in order to find out whether the movement limitation and the weight of orthosis could have an effect on energy consumption. Each gait was conducted at a comfortable speed, 2.74 km/h for 30 minutes equipped with splint whose average weight is 1.2 kg. In the result of the study, The Crutch Gait With Splint showed high Exercise Intensity compaired to Normal Gait and Splint-equipped Gait. In addtion, in The Voluntary Ventilation and Oxygen Consumption, The Crutch Gait showed higher figures than two the others and the difference was significant as well(p<0.05). As for The Calorie Consumption, it also showed higher figures than two the others but the difference was not statistically significant. Finally, in The Respiratory Exchange Ratio and The Ventilation Equivalent, there was no significant difference among three conditional variables.

The purpose of this study, using 3D printer, was tried to fabricate the short arm cast of mesh types that can be hygienic and adequate ventilation with a good radiography. We used the multi channel computed tomography (MDCT) with three dimension printer device of the fused deposition modeling (FDM) techniques. The material is used a degradable plastic (poly lactic acid, PLA). Three-dimensional images of the short arm were obtained in the MDCT and then make the three-dimensional volume rendering. Three dimension volume rendering of the short arm is implemented as a tomography obtained in MDCT. Virtual mesh type cast model was output as three-dimensional images is designed based on the three-dimensional images of the short arm. As a results, the cast output by 3D printers were able to obtain excellent radiograph images than the conventional cast, and then it can decreased itching with unsanitary, and can break down easily to the cast. In conclusion, the proposed virtual mesh type cast output by 3D printers could be used as a basis for future three-dimensional printing cast productions and offered help to patients in the real life.

In this study, we have tried to use 3D-printing technology, which is very useful for small amount production and individual personalization manufacturing to produce a cast customized by individual. To do this, we have made casts by the 3D printer in the method of fused deposition modeling technique using ABS(acrylonitrile butadiene styrene) resin which is thermoplastic plastics. The computed tomography of human hand part was used as the modeling of the cast and it was designed to circulate air well. As a result, an individual personalized cast that fitted well with the model part was produced. In addition, we could get more excellent radiography from the cast than the existing cast. In conclusion, this study of 3D-printing could be used as basic data when a similar designed structure in fused deposition modeling technique by ABS resin is printed out.

본 논문은 EBL 기반의 제어지식형 계획기에서 다양한 목표확장 방법을 사용하여 MEA의 불완전한 계획생성을 해결하는 새로운 방법을 제안한다. 계획기의 문제 공간을 탐색하는 방법 중 하나인 MEA는 현재상태와 목표상태의 차이를 줄이기 위하여 연산자를 선택한 후에, 연산자의 조건절을 현재상태가 만족하는지의 여부에 따라서 조건절의 부목표화를 결정한다. 그러나 이러한 목표확장 방법은 현재상태에서 만족된 부목표에 대한 목표확장을 하지않음으로써 문제공간 탐색에서 제한된 범위만을 탐색하므로 목표를 만족하는 최적의 계획을 생성할 수 없으며, 또한 문제를 해결하는 계획이 있음에도 불구하고 탐색범위의 제한으로 인해 계획을 생성하지 못하는 경우도 발생한다. 이와 같이 현재 상태에서 만족되어 목표확장을 하지 않은 부목표를 Anycase Subgoal이라 한다. 본 논문에서 제안하는 목표확장 방법은 ELB기반의 제어지식형 계획기를 Anycase Subgoal을 위하여 확장하는 방법으로 서, 초기의 문제공간 탐색에서 사용된 목표확장 방법에서 문제를 해결하지 못할 경우 탐색공간을 확장하여 문제를 해결하고, 문제에 적합한 목표확장 방법을 제어지식형 규칙으로 학습하여 유사한 문제에 대하여 효율적으로 계획을 생성한다.

A 5-year-old intact female mixed dog was admitted to the Veterinary Teaching Hospital for reconstructive surgery of traumatic oronasal communication in the palatal region after suffering a facial gunshot injury. The surgical procedure involved making buccal mucosal flaps as well as a transposition flap of the hard palate mucoperiosteum from the tissue adjacent to the defect, followed by applying a prosthetic appliance to protect the surgical flaps. A satisfactory outcome was obtained using a palatal prosthesis.

본 논문에서는 냉천 범람 원인을 두고 제기되고 있다는 다양한 주장을 검토했다. 냉천 설계강우를 초과하여 범람했다는 주장에 대해서, 강우량을 검토해본 바로는 설득이 안 되는 부분이 많았다. 특히 올해보다 더 많은 강우량을 기록했던 과거 호우 사상 시, 냉천이 범람하지 않았다는 것을 볼 때, 설득력이 부족하다. 만조와 집중 호우 시점이 겹치면서 범람이 발생했다는 주장은 합리적 추정으로 판단된다. 당시 최극조위가 역대 1위였으며, 역대 1위 강우량을 보인 1998년 대비 해수면의 높이가 55cm나 높았다는 데이터가 주장을 뒷받침한다. 마지막으로 교량의 부목 축적이 범람을 키웠다는 주장에 대해서 살펴봤다. 냉천교는 짧은 경간과 교각이 3개나 있어, 상류에서 내려오는 부목이 교량 구조물로 인해 축적될 잠재력이 큰 형상을 하고 있다. 교량에 부목이 축적되면 통수능이 저해하며 이로 인하여 냉천 범람이 가중되었을 가능성이 커 보인다. 기후변화로 인하여 해수위 상승위험은 점진적으로 증가할 것으로 판단되고 있는 시점에서 냉천과 같이 해안과 접하는 하천의 범람 위험 또한 증가할 것으로 판단되어, 해안 하천 관리에 큰 주의와 관심이 필요하다.

Considering that the laser range finder has the excellent resolution with respect to angular and distance measurements, a sophisticated local path planning algorithm is achieved by subgoal and sub-subgoal searching methods. The subgoal searching finds the passable ways between obstacles and selects the optimal pathway in order to reduce the moving distanced from start point to given to given goal. On the other hand, the sub-subgoal searching corrects the path given in subgoal searching in the case of which the mobile robot will collide with obstacles. Also, the effectiveness of the established local path planning and local minimum avoiding algorithm are estimated by computer simulation and experimentation in complex environment.

The purpose of my study is to provide some information on clothing for the handicapped with special needs. So I have designed clothes for the handicapped to provide some solutions for their clothing problems. These clothing designs for crutch and wheelchair users were based on solutions proposed by many researchers. The number of handicapped has been increasing gradually for years, especially the physically handicapped. Although they make use of many instruments for ease of movements and other physical conditions, most of the handicapped generally use crutches and wheelchairs. So I designed clothing for the crutch and wheelchair users. In order to ease problems in dressing and undressing, when using the crutch and wheelchair, various physical attributes of clothing should be considered: (1) Selection of fabric, (2) construction and location of the opening, (3) type and location of fastenings, and (4) design of garments for comfort and ease of movement. Clothing should also be able to satisfy psychological needs related to attractive appearance. My designs have proposed seven items of clothing. These include a cape-coat, over-blouse, one-piece dress and an pants for the crutch users. Also, a shirts, pants, and wheelchair wrap for wheelchair users will be displayed.
