본 논문은 대학생들의 과잉행동성충동장애 증상 출현율과 우울과의 관계를 알아보고자 하였다. 대학생 350명을 대상으로 Conners 과잉행동성충동장애 평정척도와 Beck 우울척도를 이용한 조사를 실시하였다. 대학생들의 과잉행동성충동장애 증상 출현율은 5.1%이였고 그 중 부주의형이 가장 높았다. 우울 정도는 $8.38{\pm}6.86$점이었고 여학생이 남학생보다 우울정도가 높았으며, 보통 우울증상과 심한 우울증상자는 2.1%이었다. 과잉행동성충동장애가 우울에 영향을 주는 모형 설명력은 33.5%로 다소 높았으며, 과잉행동성충동장애 증상과 우울 증상의 공존율은 전체 학생 중 3.1%로 나타나서, 대학생들의 성인 과잉행동성충동장애 증상 출현율과 우울은 관계가 있는 것으로 보인다. 성인 과잉행동성충동장애로 인한 다양한 문제를 고려하면 이에 대한 사회적 차원의 대책 수립이 필요한 것으로 보인다.

Nowadays many neurological diseases such as stroke and Parkinson diseases are continually increasing. Orthotic devices as well as exoskeletons have been widely developed for supporting movement assistance and therapy of patients. Robotic knee orthosis can compensate stiff-knee gait of the paralyzed limb and can provide patients consistent assistance at wearable environments. With keeping a robotic orthosis wearable, however, it is not easy to develop a compact and safe actuator with fast rotation and high torque for consistent supports of patients during walking. In this paper, we propose a novel kinematic model for a robotic knee orthosis to drive a knee joint with independent actuation during swing and stance phases, which can allow an actuator with fast rotation to control swing motions and an actuator with high torque to control stance motions, respectively. The suggested kinematic model is composed of a hamstring device with a slide-crank mechanism, a quadriceps device with five-bar/six-bar links, and a patella device for knee covering. The quadriceps device operates in five-bar links with 2-dof motions during swing phase and is changed to six-bar links during stance phase by the contact motion to the patella device. The hamstring device operates in a slider-crank mechanism for entire gait cycle. The kinematics and velocity/force relations are analyzed for the quadriceps and hamstring devices. Finally, the adequate actuators for the suggested kinematic model are designed based on normal gait requirements. The suggested kinematic model will allow a robotic knee orthosis to use compact and light actuators with full support during walking.

Purpose: The purpose of this study was to examine the effects of a cognitive training program on neurocognitive task performance and activities of daily living (ADL) in patients who had a stroke. Methods: The research design for this study was a nonequivalent control group non-synchronized design. Patients were assigned to the experimental (n=21) or control group (n=21). The experimental group received a 4-week cognitive training program and usual care (i.e., rehabilitation service), while the control was received usual care only. Cognitive function was measured with a standardized neurocognitive test battery and ADL was assessed at baseline and one and two months after completion of the intervention. Repeated measures ANOVA was used to determine changes in cognitive function and ADL over 2 months. Results: The interaction of group and time was significant indicating that the experimental group showed improvement in attention, visuospatial function, verbal memory, and executive function compared to the control group which had a sustained or gradual decrease in test performance. A significant group by time interaction in instrumental ADL was also found between the experimental group with gradual improvement and the control group showing no noticeable change. Conclusion: Findings show that the cognitive training program developed in this study is beneficial in restoring cognitive function and improving ADL in patients following a stroke. Further study is needed to investigate the long-term relationship between cognitive training participation and cognitive improvement and effective functioning in daily living.

근래에 비스포스포테이트(bisphosphonate) 투약의 부작용으로 악골괴사에 관한 보고들이 점차적으로 증가하고 있다. 최근에 보고된 유병율은 대략 0.8% - 12 % 정도이다. 하악은 상악보다 2배 정도 호발하는 것으로 보고되었고 이의 60 - 70 %는 치과진료와 연관성이 거론되었다. 임상적으로 골괴사 현상이 일어나기 전에 건강한 치주조직에 변화가 일어나는데 치유지연 점막궤양, 치아동요와 원인을 알 수 없는 연조직 감염등이 관찰되었다. 치아발거가 치과영역에서 가장 흔한 사전 처치행위로 알려져 있다. 장기적인 비스포스포네이트 투약시 세심한 예방적 치과진료가 이러한 심각한 괴사로 이어지지 않도록 하는데 절대적이다.

The purpose of this study was to determine the effect of high voltage pulsed current (HVPC) stimulation on proliferative activities of basal keratinocytes by measured nucleolar organizer region (NOR) expression and thickness of spinous layer in aged rat skin. Fifty-one weeks old twelve male Sprague-Dawley rats (300∼350g) were divided into control and HVPC stimulation groups. Each animal's hair on the back were removed. The HVPC stimulation group received an negative monophasic twin peak pulsed current stimulation with 50 V, while the control group was given the same treatment without electricity. The rats were sacrificed after 3 weeks. The biopsy specimens were fixed in formalin, embedded in paraffin and stained with hematoxyline-eosin and silver nitrate. The thickness of basal to granular layer of the epidennis were measured using a light microscope and computerized image analysis system. The number of argyrophilic nucleolar organizer region (AgNOR) were counted using a light microscope and computerized image analysis system and calculated as the mean number of AgNOR per nucleus in the basal keratinocyte. By using a Student's t-test, an increase in the thickness of basal-spinous layer (P<0.001) of epidermis can be observed in HVPC stimulation rats as compared with the control rats, whereas the thickness of the granular layer is not affected. A Student's t-test showed a significantly higher mean NOR number per nucleus of the basal keratinocyte in the HVPC stimulation rats than control rats (P<0.001). There was significantly positive correlation between the NOR number and the thickness of basal-spinous layer (r=0.80, P<0.05). These results suggest that the HVPC stimulation may increase the thickness of spinous layer in the epidennis due to increased proliferative activities of basal keratinocytes in epidennis in aged rat skin.

Introduction: We report a rare case in which the symptoms of hypersomnia were caused by cerebral infarction that occurred in the hypothalamus and hypothalamus. Case Presentation: The patient underwent Korean medicine treatments using Gami-seonghyangjeonggi-san, acupuncture, electroacupuncture, and physical therapy for 37 days. We evaluated the degree of improvement in hypersomnolence based on the amount of sleeping time and the degree of memory impairment with the patient's suggestive conditions as observed by the patient's guardian, and one-sided facial palsy using the Yanagihara Scale. As treatment was applied, sleeping time was decreased from 22 to 9 hours a day. Memory impairment did not show clear improvements as the patient could not recognize others when they visited during the period in which the patient underwent treatment. One-sided facial palsy showed no improvements and there were no changes in the Yanagihara Scale results. Conclusion: This case showed that Korean medicine treatment could be effective to relieve some of the symptoms of thalamus and hypothalamus infarction. Further research is needed to confirm the effectiveness of Korean medicine treatment.

The optimized prosthetic mass distribution was a controversial problem in the previous studies because they are not supported by empirical evidence. The purpose of the present study was to evaluate the effect of prosthetic mass properties by modeling musculoskeletal system, based on the gait analysis data from two above-knee amputees. The joint torque at hip joint was calculated using inverse dynamic analysis as the mass was changed in knee and foot prosthetic components with the same joint kinematics. The results showed that the peak flexion and abduction torque at the hip joint were 5 Nm and 15 Nm when the mass of the knee component was increased, greater than the peak flexion and abduction torque of the control group at the hip joint, respectively. On the other hand, when the mass of the foot component was increased, the peak flexion and abduction torque at the hip joint were 20 Nm and 15 Nm, greater than the peak flexion and abduction torque of the control, respectively. The hip flexion torque was 4.71-fold greater and 7.92-fold greater than the hip abduction torque for the knee mass increase and the foot mass increase on the average, respectively. Therefore, we could conclude that the effect of foot mass increase was more sensitive than that of knee mass increase for the hip flexion torque. On the contrary, the mass properties of the knee and foot components were not sensitive for the hip abduction torque. In addition, optimized prosthetic mass and appropriate mass distributions were needed to promote efficiency of rehabilitation therapy with consideration of musculoskeletal systems of amputees.
