The shoulder joint permit ate greatest mobility of any joint area carries out the importment function of stabilization for hand use. So handgrip activity is important to evaluate while assessing shoulder load in manual work. There was an association between static handgrip and shoulder muscle activity. The purpose of this study was to find out the changes of the hand grip strength according to shouter an81e. One hundred (50 female, 50 male) college adult volunteers with no known shoulder dysfunction participated subject in three positions with elbow extension: (1) shoulder $0^{\circ}$ flexion (2) shoulder $90^{\circ}C$ flexion (3)shoulder $180^{\circ}C$ flexion. The paired t-test was used to determine the different in grip strength between right and left hand at shouter position change. All, there was significiant for all three position by right and left shoulder (p<0.001). In mon, the ANOVA results revealed not a significiant F-ratio fer all three position by right and left hand. In woman, revealed significiant (p<0.05).

Background: The aim of this study was to determine the accuracy and error range of hand grip strength measurement using various methods. Methods: Methods used for measurement of hand grip strength in 34 epidemiologic studies on sarcopenia were analyzed. Maximum grip strength was measured in a sitting position with the elbow flexed at 90 degrees, the shoulder in 0 degrees flexion, and the wrist in neutral position (0 degrees). Maximum grip strength in standing position was measured with the shoulder in 180 degrees flexion, the elbow fully extended, and the wrist in neutral position (0 degrees). Three measurements were taken on each side at 30 sec intervals. The uncertainty of measurement was calculated. Results: The combined uncertainty in sitting position on the right and left sides was 1.14% and 0.38%, respectively, and the combined uncertainty in standing position on the right and left sides was 0.35 and 1.20, respectively. The expanded uncertainty in sitting position on the right and left sides was 2.28 and 0.79, respectively, and the expanded uncertainty in standing position on the right and left sides was 0.71 and 2.41, respectively (k=2). Conclusions: Uncertainty of hand grip strength measurement was identified in this study, and a significant difference was observed between measurement. For more precise diagnosis of sarcopenia, dynamometers need to be corrected to overcome uncertainty.

In order to find out whether Hand Acupuncture Therapy and Moxibustion Heat Therapy is effective to relieve dysmenorrhea syndrome, we performed a Quasi-experiment on a group of fourty females. The experiment was carried out during the period from April 20 to August 20, 1999. The group was divided into two sub-groups called "a Hand Acupuncture Therapy sub-group" and "a Moxibustion Heat Therapy sub-group" consisting of 20 females respectively. Hand Acupuncture Therapy and Moxibustion Heat Therapy were performed four times a week. Especially, in case of Moxibustion Heat Therapy, subjects were treated twice a times. The data analyzed by an SAS program. The results are as follows : 1) Hand Acupuncture Therapy and Moxibustion Heat Therapy are very effective to relieve dysmenorrhea syndrome. This study shows that in case of Hand Acupuncture Therapy sub-group, supposing that mean score of Menorrhalgia before treatment was 7.85, it became low to 4.50 when. subjects suffered the first menstruation and it was 2.50 at the second menstruation, and 1.60 at the third menstruation. In the mean score of Moxibustion Heat Therapy sub-group, Menorrhalgia before treatment was 7.85, it was 5.90 at the first menstruation(p<.05), and 3.00 at the second, and 1.85 at the third menstruation. 2) Among Hand Acupuncture Therapy subgroup, 9 subjects could hardly be relieved from the pain of dysmenorrhea at the first menstruation. So, they were treated additionally with the method of tonification and sedation of abdominal diagnosis of three constitution and became completely relieved at second menstruation. Meanwhile, 7 subjects among Moxibustion Heat Therapy also faced the same situation. So they were treated with Moxibustion on dorsum of hand and got effectiveness at the third menstruation after taking therapy. 3) Odinary dysmenorrhea syndrome are constipation, dizziness, anorexia, abdominal pain, lumbago, breast engorgement, abdominal distention, dysconcentration, nervousness, diarrhea, nausea & vomitting, apathy, restlessness, fatigue, aggression, leg pain, edema. After taking therapy, all of subjects were relieved from these dysmenorrhea syndrome at third menstruation. 4) All subjects were classified into five types of physical constitution with abdominal diagnosis of three constitution as follows: 18 cases of left kidney right yang excess, 8 cases of left yin right yang excess, 7 cases of left right kidney excess, 5 cases of left right yang excess, 2 cases of left yang right kidney excess.

The purpose of this study was to compare the effect of different methods of hand washing by counting the number of bacteria on the hand surface. Eighteen clinicians were chosen and divided into three groups, consisting of six clinicians each. Culturing of the right raw palms of all individuals was performed. Individuals in the control group washed hands for 5 seconds with antimicrobial soap. Group 1 washed their hands for 10 seconds with antimicrobial soap. Group 2 washed with an instant alcohol-based hand sanitizer. After the respective washes, re-culturing of the right raw palm was done for each member of all groups. The colony-forming units (CFU) were calculated at each time point, and the reduction rate of CFU among the three groups were statistically evaluated using student t-test. All groups showed a significant decrease in CFU, according to the time applied (P<0.01). In addition, the reduction rate of CFU between the groups were statistically evaluated with ANOVA (P<0.01). It showed statistically difference between the control group and group 1, control group and group 2. The present study confirmed that the hand washing method with antimicrobial soap for 10 seconds and hand sanitizer, including alcohol, were excellent for decreasing the number of bacteria on the hand surface.

The purpose of this study was to investigate the relations between the segments of the body, the three dimensional anatomical angle during One Hand Backhand Stroke and Two Hand Backhand in tennis. For the movement analysis three dimensional cinematographical method(APAS) was used and for the calculation of the kinematic variables a self developed program was used with the LabVIEW 6.1 graphical programming(Johnson, 1999) program. By using Eular's equations the three dimensional anatomical Cardan angles of the joint and racket head direction were defined. 1. In three dimensional maximum linear velocity of racket head the X axis and Y axis(horizontal direction) showed $-11.04{\pm}2.69m/sec$, $-9.31{\pm}0.49m/sec$ before impact, the z axis(vertical direction) maximum linear velocity of racket head did not show at impact but after impact this will resulted influence upon hitting ball. It could be suggest that Y axis velocity of racket head influence on ball direction and z axis velocity influence on ball spin after impact. The stance distance between right foot and left foot was mean $75.4{\pm}5.86cm$ during one hand backhand stroke and $72.6{\pm}4.67cm$ during two hand backhand stroke. 2. The three dimensional anatomical angular displacement of trunk in interna rotation-external rotation showed most important role in backhand stroke. and is follwed by flexion-extension. the three dimensional anatomical angular displacement of trunk did not show significant difference between one hand backhand stroke and two hand backhand stroke but the three dimensional anatomical angular displacement of trunk was bigger than one hand backhand stroke. 3. while backhand stroke, the flexion-extension and adduction-abduction of right shoulder joint showed significant different between one hand backhand stroke and two hand backhand stroke. the three dimensional anatomical angular displacement of right shoulder joint showed more flex and abduct in one hand backhand stroke. 4. The three dimensional anatomical angular displacement of left shoulder showed flexion, adduction, and external rotation at impact. after impact, The angular displacement as adduction-abduction of left shoulder changed motion direction as abduction. angular displacement of left shoulder as flexion-extension showed bigger than the right shoulder.

Kaplansky introduced the Baer rings as rings in which every left (or right) annihilator of each subset is generated by an idempotent. On the other hand, Hattori introduced the left (resp. right) P.P. rings as rings in which every principal left (resp. right) ideal is projective. The purpose of this paper is to introduce the near-rings with Baer like condition and near-rings with P.P. like condition which are somewhat different from ring case, and to extend the results of Arendariz and Jondrup.

The purpose of this study was to investigate the effects of different objects and target location of dominant hand on the non-dominant hand movement kinematics in a bimanual reaching task. Fifteen right-handed volunteers were asked to reach from same starting point to the different target point of right and left hand with grasping the objects of different size. Independent variables were 1) three different object types (small mug cup, name pen, and PET bottle), and 2) three different target locations (shorter distance, same distance, and longer distance than the non-dominant hand) of the dominant hand. Dependent variables were movement time (MT), movement distance (MD), movement mean velocity ($MV_{mean}$), and movement peak velocity ($MV_{peak}$) of the non-dominant hand. Repeated measures two-way analysis of variance (ANOVA) was used to test for differences in the non-dominant hand movement kinematics during bimanual reaching. The results of this study were as follows: 1) MT of the non-dominant hand was increased significantly when traveling with grasping the mug cup and reaching the far target location, and was decreased significantly when traveling with grasping the PET bottle and reaching the near target location of the dominant hand. 2) MD of the non-dominant hand was significantly increased during reaching the far target location, and significantly decreased during reaching the near target location with dominant hand. 3) $MV_{mean}$ of the non-dominant hand was increased significantly when traveling with grasping the PET bottle, and was decreased significantly when traveling with grasping the mug cup of the dominant hand. Therefore, it can be concluded that the changes of the ipsilateral hand movement have influence on coupling of the contralateral hand movement in bimanual reaching.

The drinking manners of the modern generaton were reviewed based on historical records. First, for reasons of health, we should reject the drinking from the same cup as others in reciprocation. Second, if the other people are older or younger brothers above the same level, pouring with one hand is all right, but if 5 years older or more, or stranger, grasp the bottle in two hands in the following manner. With the right hand under the bottle, and the left hand supporting its side, carefully pour wine not to show the palm of the hand. Third, ladies, also, can drink freely at the same table, but if people of the opposite sex are sitting together, they should pour with two hands to convey the meaning of courteous treatment. Fourth, because the level of our living is not two high, we must not order more them we can use, so that when we are finished, there will be no remainder.
