  • Nonwoven fabrics for diaper coverstock were treated with chitosan solution by pad-dry method. Two chitosans of different molecular weigh(Mw) with similar degree of deacetylation(DDA) were used: Mw 1,800(chitosan oligomer, DDA 84%). Effect of chitosan treatment on the mechanical properties was investigated using KES-FB system. Primary hand values were calculated from mechanical properties using the same equation as the men's suiting equation with minor modification, and total hand values were calculated using new KN-5LNW equation for nonwoven fabrics developed by Kawabata et al. Increase in chitosan treatment concentration increased B, 2HB, WT, LT and RC, and decreased WC continuously. Chitosan treatment affected other mechanical properties regardless of molecular weight. Considering primary hand values obtained from mechanical properties, it was found that chitosan of Mw 180,000 and chitosan oligomer provided softer, smoother, and more bulky at below 0.05% and above 0.5% treatment concentration respectively. Samples treated with 1.0% chitosan oligomer solution, and 0.01% chitosan solution of Mw 180,000 showed the best total hand values. (Korean J Human Ecology 1(2):119∼128, 1998)

  • Purpose: This study aimed to identify the level of complete knowledge about hand hygiene indications among nurses working at integrated nursing care service wards. Methods: A total of 127 nurses in eight integrated nursing care service wards completed structured sheets while observing a video based on six scenarios developed by the research team. Complete knowledge level was calculated as the percentage (%) of participants who responded correctly to all questions among participants. Complete knowledge levels according to the scenarios were calculated and compared according to general characteristics using the chi-squared test or Wilcoxon rank-sum test. Results: The complete knowledge level for each scenario ranged from 7.9% (scenario 6) to 42.5% (scenarios 4 and 5), and no one had complete knowledge of all scenarios. Only 3.1% of participants demonstrated complete knowledge in more than four scenarios, and 26.0% had complete knowledge of four or more hand hygiene moments. Complete knowledge level per scenario did not differ depending on work experience at hospitals and study wards, or prior hand hygiene training in the last year. Conclusion: As the complete knowledge level regarding hand hygiene moment is very low, it is suggested that regular hand hygiene training should be provided to nurses using video media that reflect real nursing tasks. Thus, they can acquire complete knowledge of when hand hygiene is needed or not during complex nursing work situations.

  • This study was carried out to investigate the effects of dyeing on the mechanical properties, primary hand, total hand value (THV), and total appearance value (TAV) of woven fabrics. Cotton, PET, nylon, cotton/PET, and cotton/nylon woven fabrics were used as test specimens. Each of fabric was dyed under the same conditions as the fabrics for sportswear which consumers have selected as best. Mechanical properties of specimens were measured by KES-FB system and primary hand and THV were calculated by equation KN -201-MDY and KN-301-WINTER respectively. TAV was calculated by KN (eq. 10). The results were as follows: 1. In mechanical properties. tensile energy increased when cotton and two cotton mixture fabrics were dyed and decreased when polyester and nylon fabrics were dyed. Bending rigidity and shear rigidity decreased after all fabrics were dyed except nylon and cotton/ nylon mixture fabrics showing higher rigidities. Cotton fabrics showed higher surface roughness while other fabrics did lower values after dyeing. 2. In evaluation of primary hand and total hand , four primary hands of cotton fabrics so decreased after dyeing that THV were lowered. Numeri, Fukurami, and Sofutosa in primary hand of polyester, cotton/polyester, and cotton/nylon fabrics and Koshi and Numeri of nylon fabrics increased after dyeing and therefore THV of four fabrics were improved. 3. Cotton and polyester fabrics showed higher TAV due to their lower bending and shear rigidity, while nylon and cotton/nylon fabrics did lower values due to their higher shear rigidity. 4. It was proposed that the method of dyeing or treatment for minimizing the decrease of THV of cotton fabrics and TAV of nylon fabrics should be developed.

  • A glove design which reflects the changes in hand surface by hand motion can reduce the undesirable effects of use of gloves on hand performance. The present study examined changes in hand length dimensions due to hand motion and identified significant factors affecting the length changes. Recruiting 120 males and females in their 20s and 30s having various hand lengths, this study measured 10 hand length dimensions, defined at 2 hand areas(phalangeal and metacarpal areas) for 5 digits, when the hand is stretched and in fist, and then calculated the percentage of length increase for each dimension. ANOVA and simple-effect analyses showed the length change percentages were mainly different depending on digit and hand area: 111-127% at the phalangeal area and 112-116% at the metacarpal area. The length change percentages of the index, middle, ring, and little fingers in the phalangeal area ascended in order and showed a high correlation(r = 0.94)with the ranges of motion of the fingers.

  • This study was performed to investigate the hand size growth of Korean adolescents boys. Subjects were between 14 and 19 years (n=352). We collected the right hand size data of 19 measurements from each subject using 3D hand scanner. The total 26 hand measurements were analyzed including seven calculated measurements. Subjects were divided into three age groups (early, middle and late). Their hand size were compared. The results showed that all hand length measurements were significantly difference among age groups. Adolescent boys hands were sharply grown at age 16 years old. The hand dimensions of middle age group were compared with twenties men (n=215). There were significant differences between two groups. The middle age adolescents' hands were shorter and thicker than twenties men. Subjects were also divided by weight and height. Weight and height was closely related to hand size. The heavier and taller subjects had the thicker hand. Their fingers were longer than others. The adolescent boys and twenties men who were taller than the twenties' average height (173.4cm) were compared. Twenties men's hands were longer and thinner than that of adolescent boys. These results imply that the male adolescent hands grow short and thick in the adolescent period. Fingers continuously grow up as a long and thin shape after adolescent period.

  • The purpose of this study was to evaluate the relationship between shoulder pain and hand edema in stroke patient with shoulder hand syndrome. In this study, 26 hemiplegic patients with the clinical symptom and sign of shoulder hand syndrome were evaluated. Hand volume was measured by hand volumeter, and hand edema was calculated by volume difference of both hands. Shoulder pain was evaluated using VAS (visual analog scale). and spasticity of shoulder was graded by modified Ashworth scale. The relationship among three factors such as shoulder pain. hand edema and shoulder spasticity was evaluated using correlation analysis. Results through correlation analysis among three factors are as follows : 1. Correlation between shoulder pain and hand edema was not significant$(\gamma=-.028)$. 2. Correlation between shoulder spasticity and hand edema was not significant $(\gamma=-.027)$. 3. Correlation between shoulder spasticity and shoulder pain was not significant $(\gamma=-.093)$. As the result of correlation analysis. this study shows that there was no statistically significant difference between shoulder pain and hand edema.

  • In this paper, we present a real-time hand pose recognition method to provide an intuitive user interface through hand poses or movements without a keyboard and a mouse. For this, the areas of right and left hands are segmented from the depth camera image, and noise removal is performed. Then, the rotation angle and the centroid point of each hand area are calculated. Subsequently, a circle is expanded at regular intervals from a centroid point of the hand to detect joint points and end points of the finger by obtaining the midway points of the hand boundary crossing. Lastly, the matching between the hand information calculated previously and the hand model of previous frame is performed, and the hand model is recognized to update the hand model for the next frame. This method enables users to predict the hidden fingers through the hand model information of the previous frame using temporal coherence in consecutive frames. As a result of the experiment on various hand poses with the hidden fingers using both hands, the accuracy showed over 95% and the performance indicated over 32 fps. The proposed method can be used as a contactless input interface in presentation, advertisement, education, and game applications.

  • A force-reflecting hand controller can provide the kinesthetic information obtained from a slave manipulator to the operator of a teleoperation system. The goal is to construct a compact hand controller that can provide large workspace and good force-reflecting capability. This paper presents the design and the analysis of a 6-degree-of-freedom force-reflecting hand controller using fivebar parallel mechanism. The forward kinematics of the fivebar parallel mechanism has been calculated in real-time using three pin-joint sensors in addition to six actuator position sensors. A force decomposition approach is used to compute the Jacobian. To evaluate the characteristics of the fivebar parallel mechanism, it has been compared with the other three parallel mechanisms in terms with workspace and manipulability measure. The hand controller using the fivebar parallel mechanism has been constructed and tested to verify the feasibility of the design concept.

  • The purpose of this study was to quantify the hands of fabrics for the Korean folk clothes using both a KES-FB and an artificial neural network. In order to select the proper input parameters, we calculated the correlation using step-wise regression between mechanical properties and the hand value of fabrics. For the classification, the primary hand values and total hand value, five neural networks with three-layered structure were constructed using the error back propagation algorithm and, in order to reduce errors and to speed up learning, the momentum method was selected. From the analysis of the primary and total hands using a self-constructed artificial intelligence system, the error rates of sleekness, stiffness, silkiness, and roughness compared with the judgement of expert panels were found to be 3.3%, 3.3%, 1.6%, and 4.9%, respectively, while that of the total hand was 9.83%.
