Purpose : The purpose of this study is to examine the effects of trunk stability training on improving trunk control, respiratory function, and respiratory muscle activation in stroke patients. Methods : The subjects were assigned to two groups: the intervention group (n=15) and the control group (n=15). Both groups participated in a conventional stroke rehabilitation program, but the intervention group also received trunk stability training for 30 minutes a day, 3 times a week, for 6 weeks. The main trunk stability exercise consisted of the dead bug exercise. Trunk control was assessed using a trunk impairment scale, and respiratory function (pulmonary function and respiratory muscle function) was assessed using spirometry. The data were analyzed using the Pearson correlation, independent t-test, and paired t-test. Results : Trunk control was significantly positively correlated with pulmonary function and respiratory muscle strength. Both groups showed a significant increase in trunk control and respiratory function. Conclusion : This study demonstrated that a conventional stroke rehabilitation program and trunk stability training have positive effects on respiratory function and respiratory muscle activation in stroke patients.

Background and Objectives: Maternal alcohol abuse is considered to be one of the most prominent cause of neurobiological malformations in the postnatal and adult life of the offspring. In this study, we investigated the effects of maternal alcohol drinking on the postnatal development of NPY-containing neuron, and, the influence of thyroxine treatment on the cerebral cortex and hippocampus of pups of alcohol abused mother. Materials and Method: Time-pregnant rats were divided into three groups. Alcohol-fed group A received 35 calories of liquid alcohol diet daily from gestation day 6; control pair-fed group B was fed a liquid diet in dextrin replaced alcohol isocalorically: alcohol + T4 group C received 35 calories liquid alcohol diet and exogenous thyroxine subcutaneously. Results: Group C showed prominent NPY immunoreactivity in the cerebral cortex compared to group A and B at P7. In group C, NPY-containing neurons were widely distributed in the all layers of cerebral cortex after P14. Besides, numerical decrease of NPY-containing neuron as age increases was not found in group C. However, the decrease of NPY-containing neuron was clearly observed in group A compared to group C after P14. In hippocampus, group Band C were appeared similar patterns after P7. Additionally, in group C, NPY immunoreactivity was prominently appeared in CA2 and CA3 at P14 as compared to group B. Conclusions: The present results showed the increase of intensity and number of NPY-containing neurons in cerebral cortex and hippocampus of pups of exogenous T₄ supplemented alcohol-exposed dams as compared to control pair-fed and alcohol-exposed pups at P7. It presumably suggest that NPY-containing neurons might be regulated by the early postnatal growth stimulatory effect of the exogenously supplemented T₄. Therefore, the increase of NPY synthesis caused by maternal administration of exogenous thyroxine may ameliorate fetal alcohol effect, one of the ill effects as a result of the dysthyroid state following maternal alcohol abuse.

2 차원 선형탄성 균열문제에 적합한 파괴기준을 알아보기 위해, 응력확대계수 K과 K 균열파단각과 파괴하중을 최소 변형에너지밀도 기준에 의해 구하는 유한요소 프로그램, SED를 개발하였다. 이 프로그램에서는, 6절점 삼각형 특이요소를 사용한 균열선단을 제외한 다른 부분에서는 고전적인 8절점 사변형 등매개변수 요소를 사용하였다. SED의 결과를 최대 원주방향 인장응력 기준과 최대 에너지 해방률 기준에 의한 프로그램의 결과차, 그리고 Jenq & Shah의 실험결과와 동일한 조건에서 비교하였다. 본 연구는 혼합모드 균열전파 모델의 계속적인 연구로서 이전의 최대 원주방향 인장응력 기준과 최대 에너지 해방률 기준에 의한 해석치와는 다소 차이가 있으나 전반적으로 Jenq 와 Shah의 실험치와 비슷한 양상을 보였다. To find out an adequate failure criterion in two-dimensional linear elastic crack problems, finite element program, SED, which determines stress intensity factors K, K, crack angle and peak load by the minimum strain energy density failure criterion were developed. In this program, the conventional quadratic isoparametric elements were used in all regions except the crack tip zone where triangular singular elements with 6 nodes were used. The results of SED were compared with the results of those which followed by the maximum circumferential tensile stress criterial and those by the maximum energy release rate criteria and those by Jenq and Shah's experiments of the same geometry and material properties. This study which has kept continuously as mixed mode crack propagation models is somewhat different from previous results, maximum circumferential tensile stress criterial and the maximum energy release rate criteria, but SED's result is generally similar to Jenq & Shah's experiments.

The key technology of robot is the design of the actuator. Particularly breakthroughs of power-to-weight ratio or energy-density III actuator technology have significant impacts upon the design and the control of robotic systems. To realize the anthropomorphic motion, artificial muscles such as shape memory alloy(SMA) and electro active polymer(EAP) are used. These actuators have the higher energy density than the electromechanical actuators such as the electric motor. The EAP has the property of good elasticity, but it is difficult to get the required power. The SMA has the good power density and simple structure, but the control scheme of the actuator is difficult. In this paper, temperature control of SMA wire using segment control is studied. The SMA wire is segmented by thermo-electric module(TEM). To supply constant currents in TEMs, MOSFET is used. Hysteresis in one segment of SMA wire is evaluated. The force and displacement of SMA wire are measured according to the number of segment. The program to control the temperature of TEM is developed by using LabVIEW software.

Background: The diseases are getting increasingly chronic as the fast development of medical and scientific technical advances prolong the human life span. Among many chronic diseases, the apoplexy leads to partial paralysis, speech disorder, perception disorder and paresthesia and motor disturbance. It also causes mental disorder to patients. This research was aimed to check the level of stress perceived by apoplexy patients according to the socioeconomic factors and neurological manifestations. Method: Applying the Neuman's stress measurement, we surveyed the stress level of 150 inpatients and outpatients who have been currently taken care of by the departments of neurology, neurosurgery and rehabilitation at a university hospital and two general hospitals in Busan. Results: The stress level related to the socioeconomic factors is higher in patients who have low education level, low income level, and financial dependence on offsprings. The stress level related to the neurological manifestations is higher in patients who have multiple strokes, bilateral paralysis, and other neurological sequelae (language, sensory, memory, particularly, gaiting disturbances and dependencies for active daily living). Conclusion: The results suggest that poststroke patients are highly likely to suffer from mental stress by various socioeconomic factors and neurological manifestations. Therefore, it can be concluded that poststroke patients need not only medical treatments and rehabilitation procedures but also more proactive mental remedies and social supports considering patient's backgrounds and characteristics.

This survey was carried out to investigate the usage of traditional fermented foods. Questionaries were answered by 283 female adults ranging from 20 to 60 ages in Daegu city and Kyungbuk province. 39.72% of total subjects answered that they made Meju and soybean paste by themselves. There were significant differences according to income, residential area, education level, and family size. In the results of the preference and consumption study on traditional soybean pastes, Kimchi and salted sea foods, preference of salted sea foods was the highest, whereas the consumption of salted sea foods was the lowest. The recognition of soybean pastes and traditional foods was remarkably low. However, the consumption frequency of traditional fermented foods and the recognition of soybean pastes and traditional foods were significantly increased with age.
