보행 과정에서 여러 근육이 동시에 수축하는 운동 모듈 또는 근육 시너지는 매우 중요한 중추신경계 운동조절 메커니즘이다. 본 연구는 걷는 동안 근육 간 양성 및 음성 공변 패턴을 이해하는 것을 목표로 한다. 본 연구에서는 트레드밀 보행 시 발생하는 다리 근육 활성을 근전도 검사를 통해 측정하였다. 동시 수축근육 그룹, 즉 운동 모듈을 확인하기 위해 우리는 양쪽 4 개의 다리 근육(전경골근, 내측 비복근, 대퇴직근, 내측 슬괵근)에서 근전도 데이터를 수집하였고, 이를 바탕으로 비음수행렬분해 및 주성분 분석을 수행하였다. 이후 근육 또는 운동 모듈 간의 다양한 조합으로부터 공변이 값을 계산하였고, 이원배치분산분석을 이용하여 각 조합들에서 발생하는 공변이 패턴을 비교하였다. 그 결과, 다양한 조합 사이에 유의미한 공변이 값의 차이가 발견되었다(p < 0.05). 같은 운동 모듈로 정의된 특정 근육 사이에서 발생하는 근 활성은 양성공변이를 보여주었으나 운동 모듈 사이에서는 음성 공변이를 보여주었다. 모든 근육 조합들 사이에서는 음성 공변이가 발생하였다. 운동 모듈 사이에서 안정적으로 발생하는 음성 공변이는 운동 모듈이 복잡한 운동 조정의 제어 단위(control unit) 일 수 있음을 암시하고 있다.

Since my arrival on March 15, 1986 I can only give an overview of several topics which I think might stimulate ideas and questions from the members of this technical organization. These topics will include some thoughts about the Korean automotive industry, future needs regarding manpower and cooperation among manufacturers, the oil industry and the government. Korea is experiencing a tremendous growth not only in the export market but also in domestic sales of motor vehicles. This expansion will require trained manpower in many areas of expertise. This growth in technology and manpower will require a great degree of coordination and cooperation between companies and government to reduce duplication, minimize costs and reduce reliance on foreign technology.

PURPOSE: This study examined the differences in the trunk impairment scores according to the levels of the gross motor classification system by evaluating trunk control in children with spastic cerebral palsy using the index of trunk impairment. In addition, the characteristics of trunk control disabilities were investigated according to the cerebral palsy type. METHODS: The subjects were 49 children (mean age 8.57±1.83 years, 11 with hemiplegia, 26 with diplegia, and 12 with quadriplegia) with spastic cerebral palsy levels I to IV under the gross motor function classification system (GMFCS). The coordination and balance of the children with cerebral palsy were evaluated using the index for trunk impairment. Statistical analyses were performed using a Kruskal-Wallis test, and Bonferroni analyses were used as a post-hoc comparison for any significant results. RESULTS: The median of the total scores of trunk impairment was 13 (range, 9-17), which was 56% of the maximum score. The total score of trunk impairment and subscales differed significantly according to the disease severity and type of motor disability. The scores for children with quadriplegia were the lowest compared to children with hemiplegia and diplegia. CONCLUSION: Trunk control function in children with spastic cerebral palsy was reduced, and varied according to the disease severity and types of motor disabilities. The degree of trunk impairment differed from the trunk control ability according to the degree of motor disability of children with cerebral palsy.

The purpose of this study is to examine the effect of clothing habits wearing cool or warm in daily life on motor ability. A group of ten healthy young females were divided into a cold (C) group and a warm (W) group. From autumn to winter, C group was advised to wear cool clothing, and W group, warm Clothing. The subject's physical fitness were tested in October, initial stage of the clothing training and March of the following year, final stage of the training. The measurements were taken after the subjects rested in a thermoneutral room conditioned at 23$\pm$2$^{\circ}C$ over 1 hour. The test items were weight, skinfold thickness, grip strength (right, left), back-lift strength, vertical jump, sit-ups, Irosmax, side step test, single-foot standing test with eyes closed, and standing trunk flexion. Changes in motor ability of each group between initial stage and final stage of the training were compared. 1. Muscle strength, part of the motor revelation capacity, showed no significant change in the both ,Troops. On the other hand, strength and power showed a decrease in the both groups and C group showed a sharp decrease. 2. Muscular endurance and cardio-pulmonary fitness, part of the motor continuation capacity, were increased after the training and the degree of increase was great in C group. 3. C group showed significant increase in motor coordination capacity including agility, balance, and flexibility after the training, while Wgroup showed significant increases only in balance. 4. Weight and skinfold thickness as a part of the physique showed no significant change.

The role of 5-hydroxytryptamine $(5-HT)_1A$ receptor activity in prenatal ischemia was studied, by injecting 8-hydroxy-dipropylaminotetraline (8-OH-DPAT; $50{\mu}g/kg,$ s.c.), a $5-HT_1A$ agonist on gestation day 17, and 30 min later inducing transient ischemia by ligating the uterine vessels for 30 min. On postnatal day 95, rats that had experienced prenatal ischemia showed impaired motor coordination and reduced concentration of 5-HT in the cerebellum compared with Sham-operated controls. In addition, they showed increased $5-HT_1A$ receptor densities in the cerebral cortex. Pretreatment with 8-OH-DPAT ameliorated the behavioral and neurochemical sequelae measured in the present study. The results suggest that $5-HT_1A$ receptors protect the brain from ischemic insult and/or facilitate recovery after prenatally experienced ischemia.
