The purpose of this study was to develop the pattern-making for Korean glove. To develop the pattern-making for glove this study comprehensive list of candidate hand data was reviewed and the manufacturers(career over th 15 years) were interviewed on the method of glove. The results of regression analysis(hand data) were as follows (unit: cm): wrist thumb tip length = middle finger length + 3.22, hand bread = 1.25 $\times$ middle finger length + 2.18, middle finger breadth at dist = 0.23 $\times$ index finger circumference + 0.4, maximum hand circumference = 3.15 $\times$ index finger circumference + 4.13, middle finger circumference = 0.91 $\times$ index finger circumference + 0.47, maximum hand thickness = 0.69 $\times$ index finger circumference -0.02. Hand measurements for glove pattern-making were developed: There were palmar hand length, hand circumference, index finger circumference and middle finger length.

This paper describes the bending strength properties of laminated woods which had three kinds of specimens according to finger length-12, 4.5 mm and butt joint and the acoustic emissions (AEs) generated during the test. 3-ply laminated wood beams were tension side layers (lower layers) composed of one middle lamina and two side-jointed laminae, with one butt joint ($_1BJ$), one finger joint (12mm, $_1FJ_{12}$) or one finger joint (4.5mm, $_1FJ_{4.5}$) in the middle lamina of tension side layer. And 3-ply laminated wood beams were tension side layers (lower layers) also composed of one lamina, with one butt joint (BJ), one finger joint (12mm, $FJ_{12}$) or one finger joint (4.5mm, $FJ_{4.5}$/) in tension side layer. Cryptomelia pieces were cut for butt and two finger types and glued with resorcinol-phenol resin adhesive. The results were as follows It was not effective in the bending modulus of elasicity (MOE) with IFJL type and had no difference from finger length. The bending modulus of rupture (MOR) of laminated wood beams including finger joint was the same values as that including butt feint and had no difference from finger length. It was effective in MOE with FJL type and had no difference from finger length. The effect of finger joint on MOR was much higher than that of butt joint but had no difference from finger length. The AE generation time of IFJL type was earlier than that of the control wood and the number of AE count was much more than that of the control wood. However, the AE generation time of FJL type was earlier than that of the control wood and the number of U count was much fewer than that of the control wood.

Testosterone acts to protect the heart as a male hormone. If it is secreted suitably, health, but too less it will have an bad influence in organs of the body. In particular, when normal levels of testosterone secretion is less, arteriosclerosis will be increased risk of heart diseases. According to the amount of testosterone is influenced difference in the ring finger length of male. Therefore, we organize groups of subjects in heart diseases and normal who measure these groups' length of the ring finger and index finger. With this in mind, we carried out analysis of interrelationship in length of the ring finger and heart diseases through cross-comparison analysis in this paper.

This study was performed to measure the various dimensions of the hand for Korean adults. Three hundred and eighteen males and two hundred and sixty females, age ranged 18 to 60, participated in this study. Thirty-five dimensions were selected to measure. Subjects were divided into three age groups, 18 to 29, 30 to 39, and 40 to 60, for each sex. The data were analyzed to see the differences between the age groups and sex by using SAS program. The results showed that the measurements related to breadth and thickness tended to increase as the age increased. Wrist breadth, index finger breadth(distal), index finger breadth(proximal), thumb breadth, and index finger thickness(proximal) increased as the age increased for both males and females (p<0.05). However, the measurements related to length tended to increase as the age decreased. The relationship between the parts that are length related showed high correlation. Hand length showed high correlation with palm length, middle finger length and index finger length. Males' were significantly greater than females' in every dimension (p<0.05). Also, the results of this study were compared with the data of Japanese and U.S. army. The results of this study can be used to design the hand related products.

The purpose of this study was to develop the dimension of hand pattern-making for Korean glove. The glove pattern-making has difficult problem in combination of anthropometric and engineering aspects. In addition, existing dimension data are not enough for glove pattern-making. Therefore, to develop the dimension for glove this study comprehensive list of candidate hand data was reviewed and the manufacturers(career over the 15 years) were interviewed on the method of glove. The result of comparing between the structures in hand and existing glove pattern, there draw deduction from follows. Pattern-making for glove need size of hand length, thumb length, index finger length, middle finger length, ring finger length, hand circumference, thumb-ring finger circumference and maximum hand thickness.

This study was aimed to obtain the available information for the clothing constru- ction according to the traits of the cerebral palsied. For this purpose, their abilities of eleven methods seven of fastening performance and seven finger functions were tested and their correlationships were clarified. The results are as follows : 1. The length of time needed to perform each fastening method in descending order is as follows : small button > small snap > culumn button > large button > middle button > large snap > separating zipper > velcro. As the spastic has better function than the athetoid in the performance of all fastening methods, there was a significant difference between the types of handicap and between the handi- capped and the normal, except for velcro fastening style in which there was no significant differ- ence between the types of handicap. 2. In finger functions of the cerebral palsied, according to the types of handicap there was no significant difference among grip, palm fixation and hands coordination, howefer there were significant differences among pulp pinching, lateral pinching, finger rolling and lifting control. As to the correlation between the ability of fastening performance and finger function, there was a high significant correlation between the length of time needed to perform each fastenting and finger function of hands co ordination, and that of finger rolling; and there was a significant correlation between the length of time and pulp pinching, and laternal pinching.

The relationship between morphological characteristics and sensibility of hands for beautiful hands were investigated for college woman in early twenties. Hand Emotional Quotient (HEQ) which is classified as 10 grades was newly suggested as one of the sensibility evaluation methods for the beautiful hands and was applied to assess the qualitative and quantitative relationships between morphological characteristics and HEQ. The factors influenced on the HEQ were in order as width-length ratio of hands, finger length-hand length and finger width-hand length ratios. Otherwise the influences of hand length-nail length and finger length-nail length ratios on HEQ were insignificant. The longer length of hand, finger, and nail and the narrower width of hand and finger, the higher HEQ hands get. In conclusion, it is found that all morphologic characteristics of hands influenced on the sensitivity synthetically. The data constructed on the hand's sensibility is very useful for various beauty products and service areas related to hands.

This paper proposes a biomimetic finger module to be used in a lightweight hand prosthesis. The finger module consists of finger skeleton and an actuator module driven by SMA (Shape Memory Alloy). The prototype finger module can perform flexion and extension motions; finger flexion is driven by a contraction force of SMA, but it is extended by an elastic force of an extension spring inserted into the finger skeleton. The finger motions are controlled by feedback of electric resistance of SMA because the finger module has no sensors to measure length and angle. Total weight of a prototype finger module is 30g. In experiments the finger motions and finger grip force are tested and compared with simulation results when a constant contraction force of SMA is given. The experimental results show that the proposed SMA-driven finger module is feasible to the lightweight hand prosthesis.

Objectives : Cerebral laterality is thought to be an important marker for neurodevelopment. Prenatal testosterone could influence both cerebral laterality and 2nd to 4th finger length ratio(2D : 4D). EEG coherence and 2D : 4D were examined to investigate the relationship between prenatal testosterone level and cerebral laterality. Methods : EEG was recorded in 24 healthy subjects in the eyes closed resting state. Differences in 2D : 4D finger ratio were used to discriminate "masculine finger type" and "feminine finger type" groups. The 2D : 4D ratio was lower and greater than one for the "masculine finger type" group and "feminine finger type" group, respectively. We used coherence analysis to estimate the cortical functional connectivity. Results : There were statistically meaningful relationships among cerebral functional connectivity, sex and finger ratio. Man and masculine finger type group showed higher intra-hemispheric coherence than those of woman and feminine finger type group. Woman and feminine finger type group showed higher inter-hemispheric coherence than those of man and masculine finger type group. Conclusions : These results imply that prenatal testosterone might act as important determinants of cerebral laterality. Further examination of the relationship between 2D : 4D and EEG coherence in schizophrenia could give some clues for the neurodevelopmental hypothesis of schizophrenia genesis.
