Purpose: This study examined the effect of EMG-stim related to the functional recovery of the upper extremity in chronic stroke patients with an intensive massed practice protocol. Methods: The subjects were assigned randomly to either the EMG-stim group (n=10) or sham treatment group (n=10). Both groups received conventional physical therapy, occupational therapy and FES, five times per week over a four week period. In the EMG-stim group, EMG-stim was applied to the hemiplegic wrist and finger extensors for 2 sessions for 30 minutes per day, 5 times per week over a 4 week period. As the pre- and the post-test, the following four motor tests were assessed as the function of the upper extremity clinical functional test: extensor digitorum strength test, Box and Block test, Fugl-Mayer Assessment, and Jebson-Taylor Hand Function Test. Results: In the Box and Block test and Fugl-Mayer Assessment, there were statistically significant differences between both groups as well as between pre- and post-test. The extensor digitorum and wrist extensor strength were similar in both groups. In the Jebson-Taylor Hand Function Test, there was a significant difference in simulated page turning but not in the other subtests. Conclusion: Intensive massed practice with EMG-stim intervention applied to the hemiplegic upper extremity is an effective therapeutic method for chronic stroke patients. However, a variety of intervention methods designed for stroke patients in clinical settings are needed.

This study was performed to investigate the behaviors of alkaline discharge of 'disperse dyes absorbed in polyester woven fabric. The variables invoved in the present study were; 1) pH and types of additives for the padding liquor, 2) viscosity types of alkali salts and their concentrations, and types of hygroscopic agents and their concentrations for the printing paste, 3) steaming time and temperature for the discharging process. The alkaline salts used were potassium carbonate, sodium hydroxide, and sodium carbonate. Sodium hydroxide showed less strong dischargeability than potassium carbonate and also changed shade of illuminant color accompanying a loss in the tensile strength of the fabric. Hygroscopic agents allowed to obtain stronger white dischargeability which was also depended on the types of alkali salts.

Purpose: Apraxia is characterized by loss of the ability to execute learned, skilled, sequential purposeful movements which cannot be accounted for by elementary disturbances of strength, coordination, sensory, lack of comprehension, attention, and willingness etc. For an accurate diagnosis and treatment of patients with apraxia, an understanding of the prevalence rate and clinical characteristics of apraxia is necessary. The purpose of this study was to estimate the apraxia prevalence rate. Methods: The apraxia prevalence rate was investigated via an apraxia assessment tool in 137 stroke patients, and the clinical characteristics of general stroke patients and stroke patients with apraxia were compared. Results: 14 (1 left hemiplegia, 8 right hemiplegia, 5 quadri hemiplegia) of a total of 137 stroke patients were diagnosed with apraxia. The group of stroke patients with apraxia showed lower values of mmt, mbc and fac than those of general stroke patients. Conclusion: The apraxia prevalence rate of stroke patients was approximately 10%, while the clinical function of stroke patients with apraxia was generally inferior to that of general stroke patients.

The use of ultrasonic in wet processes such as dyeing and finishing offers various benefits in terms of energy savings, reducing time, and improvement of product quality. In this study, we applied ultrasonic wave(28kHz) to accelerate alkali hydrolysis of polyester fabrics with sodium hydroxide. The alkali hydrolysis of PET fabrics were done with treated several times(20, 30, 40, 50, 60min.) and temperature(50, 60, 70, 80, 90, 100℃). Weight loss, frictional static charge, tensile strength, K/S value and surface characteristic of PET fabrics hydrolyzed with NaOH by ultrasonic apparatus were investigated and so that we studied it is possible that ultrasonic can have great potentional for commercial applications. The results are follows 1. The rate of weight loss increased about 2~3% with ultrasonic wave. To get the same rate of weight loss by alkali hydmlysis with ultrasonic waves resulted in 5~6min. shorter time and 3~4℃ lower temperature than the alkali hydrolysis without ultrasonic wave. 2. PET treated with ultrasonic showed a clean micropore stricture in which PET decompositions were removed completely and had somewhat higher static charge and air permeability than sample without ultrasonic wave. Decreases of tensile strength and K/S value were depended on the rate of weight loss rather than the use of ultrasonic wave.
