Purpose: This study was to examine the effects of hand massage and hand holding as nursing interventions on the anxiety in patients with local infiltration anesthesia. Method: The design of this study was a nonequivalent, control group, non- synchronized design. The subjects of this study consisted of 15 patients for the hand massage group, 15 patients for the hand holding group and 17 patients for the control group awaiting surgery in the operation room of a general hospitalin Daegu. As an experimental treatment, hand massage was carried out by the Hand Massage Protocol developed by Snyder(1995) and interpreted by Cho(1998) and hand holding developed by Cho(1998). The data were analyzed by SPSS/WIN, T-test, ANOVA, Cronbach's a, and the Scheffe test. Results: The hand massage group and hand holding group were more effective than the control group in reducing anxiety, VAS score, systolic blood pressure and pulse rate. Conclusion: Hand massage and hand holding are effective nursing interventions that alleviates the psychological and physiological anxiety of patients with local infiltration anesthesia. In particular, the simple contact of hand holding is regarded as an effective and easily accessible nursing intervention in the operating room.

Operation usually brings about psychological stress as well as physical stress to the patient and it greatly influences the maintenance of the homeostasis. Until now, most of the nursing research concerning the anxiety of the patient undergoing an operation has been done while the patient was under general anesthesia. Under local anesthesia, the anxiety of the patient who undergone operation is short. However, there is much demand of the operational nurses to mediate between the patient who is undergoing operation when fully conscious, as they are aware of the patient's anxiety and to decrease the patient's anxiety of this local anesthesia. Therefore, this research tries to verify the effects of the Hand-holding program on the anxiety of the operational patient undergoing local anesthesia and affirms the role of the nursing intervention. As an unequivalent control group non-synchronized designs, this research selects out 20 control groups and 21 experimental groups at random who have received cataract operation while under local anesthesia and after implementing the Hand-holding program to the experimental groups while undergoing the operation, the effect of the experiment was observed. By observing the Epinephrine, Cortisol, blood pressure, and pulse for the physical indexes before and after the enforcement of the hand-holding, and using the measurement of Speilberger(1972) for the psychological indicators for the anxiety of the patient before and after hand-holding, the results were analyzed through SAS program. As a results, intervention of hand-holding had a remarkable effect to decrease the anxiety felt by the patient and the diastolic blood pressure also was effectively decreased. On the other hand, through the decrease of the systolic blood pressure was also observed, it was not statistically significant. In the Epinephrine and Cortisol indicators, the intervention of hand-holding was revealed to have an insignificant effect. The Hand-holding was revealed to have an indicators, the intervention of Hand-holding was revealed to have an insignificant effect. The Hand-holding program may be said to have an effect which decreases the psychological anxiety of the patient undergoing local anesthesia.

This study was designed to investigate the effect of a hand massage program on anxiety and immune function in patients during cataract surgery. The hand massage program, in this study, consisted of hand massage and hand-holding. The subjects were sixty-three patients, thirty for the experimental and thirty-three for the control group, who were admitted at Kang Nam St. Mary's Hospital for cataract surgery. This study was carried out from December 10, 1997 to February 26, 1998. The level of anxiety as measured by the Visual Analogue Scale, systolic blood pressure, diastolic blood pressure, and pulse rate were measured before, after hand massage, and after hand-holding. Epinephrine, norepinephrine, cortisol, blood sugar levels, neutrophil, lymphocyte, and natural killer cell percentages also were measured before hand massage and five minutes before the end of the operation. Data were analyzed by t-tests, ANCOVA, repeated measures ANOVA, and Bonferroni multiple comparisons. The results were as follows : 1) After hand massage, psychological anxiety levels decreased significantly compared with before hand massage in the experimental group, not in the control group. After hand holding, there were significant decrease in both groups. 2) There were not significant differences on systolic blood pressure, diastolic blood pressure, and pulse rates in both groups. 3) The hand massage program decreased epinephrine, norepinephrine, and cortisol significantly in the experimental group, and increased epinephrine, norepinephrine, and cortisol in the control group. 4) There were no differences in blood sugar levels, neutrophil and lymphocyte percentages in white blood cells after the hand massage program. However, natural killer cells in lymphocytes were significantly increased in the experimental group. These findings indicate that a hand massage program could be a effective nursing intervention in decreasing the psychological and physiological anxiety levels and improving immune function in clients having cataract surgery under local anesthesia.

As a basic experiment for robot hand for transplanting plug seedling, the experimental robot hand system which moves up and downward vertically, and allows hand blade to open and close was made. The system was constructed with the robot hand mechanism, the tray, the plug seedling, and the measuring equipments. The penetrating force and holding efficiency were analyzed according to the soil moisture and the variation of hand blade angle. The highest holding efficiency could be obtained at the penetrating angle of approximately from 0 to 0.36 degree and at the moisture content of soil from 71% to 75%. The external force acted on the robot hand should maximum force when the robot hand was penetrated to soil, minimum of approximately 30.4 N when the penetrating angle was 0$^{\circ}$ and moisture content was 66-70%. It was increased with increasing or decreasing the Penetrating angle from 0 degree and also with increasing or decreasing the moisture content of soil from 66-70%. For optimal design of the robot hand and manipulator, the external force acted on robot hand had to be based on the returning force of soil, when the robot hand was penetrated to the soil. In consideration of safety ratio, the appropriate external force seemed to be 39-49 N.

In this research, two studies show that the bodily experience of holding objects in the hand is tied to the mental concept of acquiring material wealth. Holding objects in the hand (a) increased people's desires for possessing fairly luxurious goods (Study 1) and (b) made people judge a controversial issue (e.g., "sweatshops" run by global companies) more favorably based on wanting to generate more wealth for individuals and society rather than on humanitarian concerns (Study 2). These results provide evidence that the bodily experience not only helps to represent an abstract concept but also can shape attitude and judgment congruent with the metaphor represented in the bodily experience.

This study was performed to analyze the holding pace and decision factors of tractor in Korea and Japan, which probably should be used for making master plan of agricultural mechanization. The logistic function is used for holding pace estimation of tractor, and log-log function for analysis of decision factors. The results of this study are as follows: First, the increasing rate of the total amount of holding tractor power in Korea has been over that in Japan during 1980∼、94 which is now, however, under Japan. So, it could be forecasted that the per tractor holding power in Japan will increase continuously, and will be over 30PS in the short run. Second, the most important one of decision factors to support tractor demand is agricultural income in Korea, but on the other hand Non-Agricultural Income in Japan. From these, the fast increase of total amount of holding power of tractor in Korea could not expected, because Korea Agriculture has some difficulties to increase Agricultural Income. There are differences on the holding pace and decision factors of tractor between Korea and Japan, therefore, the plan of agricultural mechanization should be made in accordance with self-features.

This study aims to measure maximum holding times(MHTs) of symmetric and asymmetric whole body postures, and to compare three representative observational methods including OWAS, RULA, REBA, based on the MHTs. An experiment was conducted for obtaining the MHTs, in which hand position was used as experimental variable, and the MHT and subjective discomfort rating as dependent variables. The hand position was defined by the percentage of the shoulder height(%SH), the percentage of the arm reach(%AR) and rotation angle(R). The results showed that three independent variables of %SH, %AR and R significantly affected on the MHTs at ${\alpha}$=0.01, and that the MHTs were negatively linearly related to the discomfort scores of Borg CR10. It was also revealed that OWAS and REBA were less sensitive to postural stress than RULA. In addition, OWAS and REBA underestimated postural load of given postures compared to RULA. Therefore, it is recommended that among the three observational methods investigated in this study, RULA be used for a more precise evaluation of postural load.

The Fenton reaction, which evaluates the electrochemical durability of polymer membranes of polymer electrolyte fuel cells (PEMFC), and the degradation of polymer membranes by OCV holding method are compared. The Fenton reaction is a method that can evaluate the chemical durability of the polymer membrane at outside the cell in a shorter time than the OCV Holding method. The Fenton reaction was carried out at 30% hydrogen peroxide, 10 ppm iron, and $80^{\circ}C$ for 24 hours. OCV Holding was driven at $90^{\circ}C$, 30% relative humidity and OCV for 168 hours. The Fenton reaction caused a lot of degradation inside the polymer membrane. On the other hand, in OCV Holding, the membrane thickness was thinned by the entire surface and internal degradation. The fluorine emission rate was more than 10 times higher than that of OCV Holding due to the Fenton reaction. The hydrogen permeation rate increased about 30% at 24 hours of Fenton reaction. At OCV Holding, hydrogen permeability decreased after 24 hours and then increased. As a whole, there was a difference in a membranes deteriorated by Fenton reaction and OCV Holding.

In this paper, we propose the gaussian mixture model based pattern classification algorithm of forearm electromyogram. We define the motion of 1-degree of freedom as holding and unfolding hand considering a daily life for patient with prosthetic hand. For the extraction of precise features from the EMG signals, we use the difference absolute mean value(DAMV) and the mean absolute value(MAV) to consider amplitude characteristic of EMG signals. We also propose the D_DAMV and D_MAV in order to classify the amplitude characteristic of EMG signals more precisely. In this paper, we implemented a test targeting four adult male and identified the accuracy of EMG pattern classification of two motions which are holding and unfolding hand.
