Purpose: Myocutaneous flap was widely used for trochanteric pressure sore but it had many drawbacks such as donor site morbidity, dog-ear deformity and functional muscle sacrifice. We have performed fasciocutaneous flap based on perforating vessels and succeeded in overcoming its drawbacks. Methods: We experienced 11 cases of perforator-based fasciocutaneous flap for the coverage of trochanteric pressure sore in 9 patients, 2 cases of which were bilateral. The ambulatory status of patient group is as follows: 6 of them used a wheelchair, 2 of them are free walking, 1 of them use a wheelchair or crutches. Flap was supplied by cutaneous perforating vessel of descending branch of the lateral circumflex femoral artery and the third perforating artery of the deep femoral artery. The size of wounds were from $4{\times}6.5cm$ to $10{\times}13cm$. Results: We did not find any flap loss or congestion except 2 partial wound dehiscences and 1 wound infection. Donor site morbidity was not found. We observed no recurrence of the pressure sore during the 2.5 year follow-up period. Conclusion: We considered that perforator-based fasciocutaneous flap could overcome the traditional drawbacks of the conventional myocutaneous flap and its modified flap for trochanteric pressure sore. And this flap has many advantages for covering trochanteric pressure sore without any donor site deformity and morbidity, which would greatly improve the aesthetic result.

Purpose: The purpose of this study was to compare the changes in the contact area, maximum pressure, maximum mean pressure, and maximum force of functional insoles and general insoles when walking. Methods: Foot pressure was measured by the ignition of functional insoles and general insoles on Company N shoes. The foot pressure was measured using a precision pressure distribution meter (Pedar - X mobile system, Novel, Germany). Each insole sensor contained 99 independent cells and was inserted between the foot and the shoe. A wireless Bluetooth-type program was used to measure the pressure detected by the measuring insoles. In order to eliminate adaptation and fatigue caused by wearing the guide during the experiment, sufficient rest was taken between each experiment, and the wearing order was randomly selected. Results: Functional insole significantly increased the forefoot and midfoot (medial, lateral) (p<0.05), while total foot, forefoot, and rearfoot peak pressure significantly decreased (p < 0.05) compared to the general insole. Conclusion: In the functional insole, a high contact area was measured inside, even in the middle of the foot, leading to a proper change in foot pressure. It was confirmed that the contact area was reduced and dispersion occurred well. In addition, it was found that the maximum pressure in the front and back of the entire foot was reduced, so the weight pressure dispersion in the functional insole was evenly distributed, and the maximum average pressure change was similar.

Many neurologists, particularly whose subspecialty is in peripheral neurology, may agree that patients with peripheral neuropathy often complain of the "restless legs" symptoms. These symptoms seem to share the typical features of the so-called "restless legs syndrome (RLS)", i.e., unpleasant sensations in the leg/feet, worsening in the evening or at night, and the partial relief of the positive sensory symptoms by the movements such as walking, shaking or rubbing. In fact, a higher incidence of RLS was reported among the neuropathic patients, and peripheral neuropathy was found to be more prevalent in patients with RLS than in general population. Moreover, RLS share many risk factors with peripheral neuropathy such as diabetes, uremia, amyloidosis and cryoglobulinemia, which suggests that peripheral neuropathy may play a pathophysiologic role in the development of RLS.

In patients with cerebral palsy, dental treatments, which require absolute patient's corporation, have many difficulties because of muscle spacity, involuntary muscle movements and spasm. Especially in endodontic treatments which very meticulous instrumentation is needed, these muscle discordances may lead to unexpected accidents such as tissue damage while filing, over-instrumentation and swallowing instruments. Also, taking radiographs for measuring canal length is often hindered by walking and movement disorders. This paper is to present a clinical case of one-visit root canal treatment using electrical apex locator under general anesthesia in a cerebral palsy patient.

A motion pattern generation is a process of calculating a certain stable motion trajectory for stably operating a certain motion. A motion control is to make a posture of a robot stable by eliminating occurring disturbances while a robot is in operation using a pre-generated motion pattern. In this paper, a general method of motion pattern generation for a biped walking robot using universal approximator, learning neural networks, is proposed. Existing techniques are numerical methods using recursive computation and approximating methods which generate an approximation of a motion pattern by simplifying a robot's upper body structure. In near future other approaches for the motion pattern generations will be applied and compared as to be done.

The rebuilding method for old apartment housing blocks has merits of providing new buildings and larger private living spaces. However, it causes many serious urban problems, such as shortage of infrastructure capacity, traffic congestion, reduction of building life, and deterioration of open space quality. Nowadays, remodeling is accepted as a way of overcoming such negative effects of the rebuilding method. This study focuses on the various techniques of remodeling. The results of this research are as follows; First, old apartment blocks provide poor level of service in general, so they have problems of bad accessibility, deterioration of facilities, and degraded landscape. In many cases, there is a hindrance from walking freely and security problem due to illegal privatization of public spaces. Second, various remodeling techniques are required to meet residents' different needs. The residents of apartment housing value private space above public space, and show low level of willingness to pay cost for remodeling. Third, based on these findings, some remodeling techniques are suggested - integration of a space to another, expansion of spaces, connection of spaces, reuses of roofs and walls, relocation and renovation of paths between buildings, and so on.

A 3-year-old black Thoroughbred colt weighing 500 kg was admitted to the Equine Hospital of Korea Racing Authority (KRA) due to the chronic gait abnormality of the hindlimbs. The history revealed that the patient had run and fallen onto the fence of the farm about at the age of 1 year old and the lameness had been worsening insidiously since the accident. The degree of lameness was 2/5 in accordance with the AAEP lameness grading system in both hindlimbs at hand walking and trot. The lameness was exacerbated at lunging clockwise and counterclockwise on both hindlimbs. The definitive diagnosis of the bilateral osteoarthritis of coxofemoral joint was established using radiography under general inhalation anesthesia. The prognosis was considered to be poor with low expectancy for racing and the colt was expelled from the racecourse eventually. The clinicians are required to consider the possibility of osteoarthritis of coxofemoral joint presented with chronic hindlimb lameness although it is rare. This is the first report on the bilateral osteoarthritis coxofemoral joint in Republic of Korea.

In this paper, we developed a miniaturized humanoid having the new joint mechanism. In general, the high torque actuator and the joint mechanism having three coincided axes are important in development of the miniaturized humanoid. By using the swash plate, which is generally used in three axes rotor mechanism, we developed a new three-coincided-axes joint mechanism and a miniaturized humanoid having the joint mechanism at its hip and ankle joints. Since the joint mechanism has a pair of parallel drive motors for each axis, the driving torque of the joint mechanism is very high. Futhermore, thanks to the three-coincided-axes mechanism, the solution of the inverse kinematics is simple and computationally efficient, and the resulting walking behavior of the humanoid becomes natural.
