본 연구에서는 미얀마, 베트남, 일본에서 외부문명의 영향을 받은 것으로 여겨지는 정령숭배의 특징에 대하여 논하고자 한다. 우선, 각 국가의 전승을 비교해볼 때 정령숭배에 있어서 충격적인 상황 속에서 사망한 이들에 대한 신앙이 중요하다는 점을 지적하였다. 다음으로 정령의 형성에 있어서 정치적 역할이 개입되었다는 사실을 논하였다. 마지막으로 종교 혼합주의는 성(性, gender)과 관련되어 있음을 주장하였다.

Rehabilitation of upper limb motor function of hemiplegic patient must maintain interest and demand a device for a quantitative evaluation of rehabilitation training. In this paper, we developed the device that is composed of arm cradle, handle, and balance ball for rehabilitation exercise. We have performed experiment for validity as to whether to use the rehabilitation device when tilting the upper extremity training device developed to measure changes in the EMG signal to the main upper limb muscles for 7 healthy volunteers. We have analyzed muscle activation signals on agonist and antagonist as a reference in the muscle contraction and relaxation in the upper limb extension and flexion when the balance-handle device is tilted to front-rear and left-right. The experimental results showed that a tendency of muscle activation of biceps, triceps, and deltoid used in upper limb motor function of hemiplegic patients from extension and flexion evaluation items of Fugl-Meyer Assessment(FMA). These results may be helpful for rehabilitation training for upper limb motor function of hemiplegic patients by utilizing a developed unit.

This study analyzed the rear foot angle of the supporting leg and the anatomical rotation angle of the kicking angle in soccer instep kick and drew conclusions as follows. When the supporting leg was landing on the ground, the valgus angle of the ankle joint reached the maximum peak, and plantar flexion was slightly different in the timing of the maximum peak between the two groups. The flexion angle of the rear foot was statistically significantly different between the two groups, and the movement of the crus on the landing of the supporting foot did not show a statistically significant difference between the groups. The crus leaned backward most before the impact, and the side to side gradient of the crus on impact was $22^{\circ}$. The flexion/extension of the hip joint of the kicking leg reached the maximum peak when the supporting foot was landing on the ground, and at the moment, the maximum extension angle of the hip joint was over $30^{\circ}$. The flexion angle of the knee joint of the kicking leg was largest after landing. While the maximum plantar flexion angle and maximum valgus angle of the ankle joint were not significantly different between the two groups, the maximum external rotation angle was significantly different.

The purpose of this study is to offer basic data for the fall prevention by analyzing the kinematic difference between the lower limb joints and the lower extremities in elderly people's walking given the lower-limb resistance exercises. For this, three-dimensional image analysis was carried out by selecting 7 elderly women from over 70s to under 80 years old. To obtain the three-dimensional location coordinates in the lower limb joints and the lower extremities, it shot with 100Hz/s by using MCU(Qualisys, Sweden) camera. The shot image gained raw data on the location coordinates by using QTM(Qualisys, Sweden). As a result of calculating three-dimensional angle by using program of Matlab 6.5, the following conclusions were obtained. Flexion and extension in the thigh and the lower-leg extremities were indicated to be big in motion of flexion after exercising at E5. Foot segment indicated statistical difference while showing eversion at E4. Knee joints showed flexion at E4 after exercising. Ankle joints showed statistical difference while indicating motion in inversion at E3 and in eversion at E4(p<.05).

In this paper, a muscle motion sensing system and an artificial arm control system are studied. The artificial arm is for the people who lost one's forearm. The muscle motion sensing system detect the intention of motion from the upper arm's muscle. In sensing system we use flex sensors which is electrical resistance type sensor. The sensor is attached on the biceps brachii muscle and coracobrachialis muscle of the upper arm. We propose an algorithm to classify the one's intention of motions from the sensor signal. Using this algorithm, we extract the 4 motions which are flexion and extension of the forearm, pronation and supination of the arm. To verify the validity of the proposed algorithms we made experiments with two d.o.f. artificial arm. To reduce the control errors of the artificial arm we also proposed a fuzzy PID control algorithm which based on the errors and error rate.

Gait analysis has been conducted in various environments, but the biomechanics during the transition from uphill walking to downhill walking have not been reported. The purpose of this study is to investigate the knee and ankle joint kinematics and kinetics during walking on a triangle-shaped slope compared with those during level walking. Kinematic and kinetic data of eighteen participants were obtained using a force plate and motion capture system. The greater peak ankle dorsiflexion angle and moment and the peak knee extension moment were observed (p<0.05) during both uphill and downhill walking on the triangle-shaped slope. In summary, uphill walking on a triangle-shaped slope, which showed a peak knee flexion of more than $50^{\circ}$ with greater peak knee extension moment, could increase the risk of patellofemoral pain syndrome. Downhill walking on a triangle-shaped slope, which involved greater ankle dorsiflexion excursion and peak ankle dorsiflexion, could cause gastrocnemius muscle strain and Achilles tendon overuse injury.

Lard was randomly interesterified to improve handling efficiency with increase of plasticity, and it's physicochemical properties and adaptability for making pie were investigated. Fatty acid and triacylglycerol composition were not changed after interesterification. Interesterified lard could be useful during winter because the handling was convenient due to drop in the temperature range of $18{\sim}23.5^{\circ}C$ in lard and $13{\sim}19.5^{\circ}C$ in interesterified lard with SFI $15{\sim}25$. Interesterified lard was decreased in the extensibility by change of crystal form, and not suitable for making pie as the inferior characters for layers forming, appearance and shortness. But interesterified lard mixed with plastic fat of high extensibility showed the possibility of making pie, and the maximum mixture ratio was 50% for good pie quality.

This study aims to develop the stance-control typed 4-bar linkage orthotic knee joint that replace the locked orthotic knee joint for the disabled with poliomyelitis and muscle weakness of lower limb. Unlike the existing stance-control orthotic knee joint, there are no needs of electric power, connecting circuit, bulky compomnets, etc, because this 4-bar linkage orthotic knee joint is controled by geometric locking. To evaluate the 4-bar linkage orthotic knee joint, a subject participated in this study who has been diagnosed with lower limb poliomyelitis and have used locked type orthotic knee joint. In the results of analysis of subject's gait using 3-dimentional motion analysis system, this 4-bar linkage orthotic knee joint provide the stability during stance phase and knee flexion during swing phase.

목적 : 요통 환자에서 Modified-Modified Schober Test (MMST)와 관절 운동 범위를 비교하여 시각 통증 등급 평가에 있어서 타당도의 우위를 추정하여 보고자 하였다. 방법 : 요통으로 입원한 31명의 환자들을 대상으로 MMST, 관절 운동 범위 및 시각 통증 등급을 주 3회씩 입원 기간 동안 측정하였다. 각 측정 방법의 시행 순서는 무작위로 선택되었으며, 환자들은 맨발로 환자복을 입은 채 측정하였다. 결과 : 각 자료의 상관성을 분석하기 위하여 피어슨 상관계수가 사용되었다. 요추의 MMST 측정값(r=-0.61 ; 99%CI)이 요추의 신전 및 굴곡의 관절 운동 범위 측정값보다 시각 통증 등급에 통계적으로 의미 있게 나타났다. 또한 요추의 MMST 측정값(r= -0.77 ; 99%CI)은 요추의 신전 관절 운동 범위 측정값보다 요추의 굴곡 관절 운동 범위 측정값과 통계적으로 의미 있게 나타났다. 결론 : 이상의 결과를 통하여 요통 환자의 평가에 있어서 MMST가 관절 운동 범위보다 높은 타당도를 가지는 것으로 추정된다.
