  • In this paper, gimbal camera control through smart gloves was implemented to increase convenience and accessibility to the control of drones used in various fields. Smart gloves identify human gestures and transmit signals through Bluetooth. The received signal is converted into a signal suitable for the drone through a GCS (Gound Control Station). Signals from smart gloves are expressed in a quaternion method to prevent gimbal locks, but for gimbal cameras, conversion is required to use Roll, Pitch, and Yaw methods. The data conversion mission is performed in the GCS. The GCS transmits an input signal to the control board of the drone through Wi-Fi. The control board generates and outputs the transmitted signal in a PWM manner. The output signal is input to the gimbal camera through the SBUS method and controlled. The input signal of the smart glove averaged 0.093 s and up to 0.099 s to output to the gimbal camera, showing that there was no problem in real-time use.

  • Objectives: This study was aimed to investigate the methods to reduce operator's radiation dose when taking intraoral radiographs with portable dental X-ray machines. Materials and Methods: Two kinds of portable dental X-ray machines (DX3000, Dexcowin and Rextar, Posdion) were used. Operator's radiation dose was measured with an 1,800 cc ionization chamber (RadCal Corp.) at the hand level of X-ray tubehead and at the operator's chest and waist levels with and without the backscatter shield. The operator's radiation dose at the hand level was measured with and without lead gloves and with long and short cones. Results: The backscatter shield reduced operator's radiation dose at the hand level of X-ray tubehead to 23 - 32%, the lead gloves to 26 - 31%, and long cone to 48 - 52%. And the backscatter shield reduced operator's radiation dose at the operator's chest and waist levels to 0.1 - 37%. Conclusions: When portable dental X-ray systems are used, it is recommended to select X-ray machine attached with a backscatter shield and a long cone and to wear the lead gloves.

  • The aim of this study is to investigate problems with both fit and abrasion of golf gloves through a survey of golf usage among golfers over the age of 30, as well as by analyzing the golf glove industry with an emphasis on the size system and marketing situation. In addition, this study aims to suggest the basic raw materials for improving the design of golf gloves through physical properties inspections. The results of the analyses support the following suggestions. First of all, dissatisfaction arose from improper measurement in glove length. The survey showed that most problems occur in the pinky finger, while only the length of the middle finger of the glove is recorded based on Korean Standard Anthropometries Measurement. Clearly, proper measurements of every finger need to be included in the system. Secondly, the survey results clearly indicated regions 7(palm area) and 3(second finger area) as the areas requiring reinforcement. While the method of patching another layer with the same material is commonly used in the current glove market, materials other than genuine leather are unable to complement the abrasion. This study suggests that another layer of refill type genuine leather, which scored best in the physical properties inspection, needs to be patched onto regions 7 and 3.

  • In both cosmetic and functional aspects, loss of digital pulp is a common problem. Compound or composite defects of the hand and fingers with exposed denuded tendon, bone, joint, or neurovascular structures may require flap coverage. Most often these lesions can be repaired by using simple local flap, neurovascular flap, thenar flap, and cross-finger flap. But microvascular reconstruction is sometimes needed for large defects. But Authors do not recommend these procedures in case of severe crushing injuries involving multiple finger pulp losses because they have possibility of damage of the vascular network and infection. So we applied distant flaps such as chest flaps, groin flaps, abdominal flaps and etc. And then we applied surgical rubber gloves for remodeling the flap after cutaneous healing. We have acquired satisfactory results, after the simple molding method for distant flap finger by using surgical rubber gloves treatment.

  • This study analyzed firefighter's actual wearing condition of turnout gear The results are as fellows: 1. When a firefighter is employed, Korea applies only the minimum of firefighters stature and weight but America applies both the minimum and the maximum. The choice of size is highly related with stature more than chest circumference. 2. The satisfaction degree of thermal barrier is very low, 3%. They used rubber gloves rather than heatproof gloves. This is more serious in small country like 'up', 'myun' than in cities. For laundering, they used sprinkling method with firefighting hose. Firefigthers hoped that their clothes could be classified tv the seasons and fire places. 3. frefighter had high unsatisfaction with the movement of hands and leges in the aspect of movement adjustability, air permeability, weight, body temperature regulation, and breathing in the hygenic aspect, fire resistance, thermal resistance property, water proof, chemical reactivity and electrical conductivity. Thev were also unsatisfied with water proof boots and gloves. They were generally satisfied with helmets but firefighters over 90kg of weight were rather unsatisfied. 4. The satisfaction degree for physical fitness was very low and the items with which they were not satisfied depend on physical features. 5. To develop turnout gear, they wanted changes in design, material and size. Reflection tape need to be replaced with high quality products and they wanted the use of velcro and zipper in fastening system.

  • The purpose of this study was to provide basic information requisite in the new sizing system for gloves. KS glove standards' size dimensions, size designation and labeling systems were analyzed. Also, KS glove standards' control sizes were compared to the anthropometric data of 824 Korean adults taken in the previous study. As well, the ISO hand size system was also compared to the anthropometric data of the previous study according to frequency tables of hand length and hand circumference. The size dimensions showed differences among KS standards and there was no size designation and labeling systems existed in KS standards. Among KS glove size systems, protective rubber gloves for radioactive contamination and surgical rubber gloves' size which followed ISO system were accurately indicate the hand size of the person a glove is intended to fit. ISO glove sizing system comprised the control dimensions of hand length and hand circumference. The coverage of ISO size A was 84.8% which was highest among ISO size A. B, C. And in hand circumference 178, 191, 203, 216mm showed the frequencies above 3% and in hand length 167, 175. 183, 191, 199mm showed the frequencies above 3%.

  • Purpose: This study was conducted to evaluate the incidence and risk factors for surgical glove perforation during operation. Methods: During the month of december 2008, a total of 1,400 pairs of surgical gloves used in major operations was collected in a tertiary hospital. All gloves were examined immediately after operation using the standardized water-leak method to detect any perforation. Incidence of the glove perforation was counted according to the type of operation, operation time, the number of involved personnel, perforation sites, and the manufacturing companies. Results: Out of 2,800 gloves examined, 312 perforations were detected comprising 11.1% of samples. In terms of the type of operation, the perforation incidence varied from 5% to 20%, and the perforation rates in CS (20%) and NS (18%) (p<.001) were significantly higher than those in other departments. The 1st assistant or scrub nurse got glove perforation more frequently than the 2nd assistant or operator (p<.001). Longer operation time was associated with higher incidence of perforation evidently (p<.001). In terms of the sites, the thumb and index finger were more frequently perforated than other sites (4.1% and 3.4% respectively) without any differences between left and right side. Conclusion: Risk factors for glove perforation including the department of operation, operation time, participating personnel, and location of perforation should be taken into account to improve surgical safety.

  • The purpose of this study was to analyze the three-dimensional hand-related dimensions of elderly women aged 70 to 84 years and to characterize them to develop safety gloves for dementia patients. The 3D data from the 8th Human Size Survey of the National Institute of Standards and Technology, Size Korea, were analyzed using the SPSS 26.0 program. The straight thumb length was longer in elderly women aged 70-74 than in those aged 80-84. To analyze the hand type of elderly women, four factors were categorized: hand and finger horizontal factor, hand vertical factor, finger digit V thickness factor, and finger length factor. Elderly women's hand types were categorized as 'long hands and thin fingers', 'thick hands with long fingers', and 'short hands and thick little fingers'. Elderly women aged 70-74 years and 80-84 years were analyzed as having the most 'long hands and thin fingers' type, while older women aged 75-79 years were analyzed as having the most 'thick hands and long fingers' type. It is known that the fingers get thicker and the size of hands increase as age advances, but by the age 80, there is a change in the size of hands again. In future research, it would be worth expanding to other age groups to explore differences between age groups and to develop safety gloves for real-world dementia patients based on the hand types analyzed.

  • Propose : In this study, we evaluated whether powder on surgical gloves is a cause of postpuncture backpain in children. Mothods : In 164 children with meningitis between July and September 1997, we did not remove powder from surgical gloves. However, in 149 children with menigitis between May and October 2001 the powder was removed from the surgical gloves. Results : Out of the 164 patients in 1997, 41 cases(25.00%) were found to have postdural puncture backpain. On the other hand, out of 149 patients in 2001, with whom we used gloves from which the powder was removed, we found only 8 patients(5.36%) with postdural puncture backpain. Conclusion : We conclude that the powder on surgical gloves is one of the main causes of postdural puncture backpain in children.

  • This study was conducted at an automobile assembly line located in Kyonggi-do, Korea from January 16 to February 28, 1995. The purposes of this study were to assess worker exposures to hand-arm vibration and the performance of gloves for reduction of vibration. The exposure to vibration was measured using to the ISO 5349(1986) method. Vibration acceleration and frequency spectra for each tool were determined on-line replicating actual working conditions and analyzed together with exposure time for evaluating individual worker exposure. Eight pneumatic hand tools, 60 workers exposured to hand-arm vibration, and three pairs of gloves were involved in this study. Results are summarized as follows. 1. Dominant frequencies of vibration for all tools(n=8) measured in this study ranged from 250 Hz to 800 Hz. 2. There was no significant correleration between dominant frequencies and free running speed (p>0.05). 3. Total predicted exposure times of using impact, hammer type did not exceed 40 minutes, but metal finish task, using grinder and sander exceeded 40 minutes. Total exposure time affected significantly the frequency-weighted, 4 hr equivalent acceleration. 4. Predicted prevalence and observed exposure period data were compared in workers(n=60), according to ISO 5349. In this results, 23(50.0 %) and 24(48.07 %) persons exceeded the mean latency periods for vibration-induced white finger(VWF) at 10 % (n=46) and 50 % (n=52) standards, respectively. On the basis of ISO equation, mean latent periods for VWF were 3.23, 4.72 years at 10 %, 50 % standards, respectively. 5. Reduction of vibration by gloves was evaluated. Since impact pneumatic tools produced low frequency vibrations, conventional gloves did not provide any protection. Gloves A and C amplify somewhat the signal at frequency below 400 Hz; the attenuation increases progressively by frequency to reach 18 dB ($7.94{\times}10^{-6}m/s^2$) at 1,000 Hz, slightly worsening Glove B did not provide any protection and made the situation slightly worse. However, since they make the hands warm, the occurrence of vibration-induced white fingers may be reduced.
