PURPOSE: This study examined the changes in the handgrip strength, dexterity, and hand function according to the presence or absence of gloves and types of gloves. METHODS: Seventy-six adults in their twenties (male: 24, female: 52, mean age 21.04 years) were the subjects of this study. The handgrip strength, dexterity, and hand function were evaluated with bare hands without gloves, poly gloves, and latex gloves. The handgrip strength was measured using a dynamometer, and three pinch strength tests were performed: tip pinch, lateral pinch, and three-jaw pinch. The hand dexterity was evaluated using the Minnesota manual dexterity test, and the hand function was evaluated using the Jabson-Taylor hand function test. RESULTS: There was no difference in the grip strength depending on whether the gloves were worn. The hand grip, dexterity, and hand function showed significant differences according to the type of glove. Regarding the handgrip, dexterity, and hand function, the latex glove had the best function, and the poly glove had the lowest function. CONCLUSION: There was a difference in dexterity among the hand functions but no difference in grip strength according to the type of glove. The results suggest that the use of latex gloves in daily life be recommended.

This study assessed the microbiological hazards of gloves worn during the shell shucking process of the oyster Crassostrea gigas, and we suggest an in situ method for minimizing microbial contamination. The study consisted of two groups, one in which the working gloves were periodically replaced (PRG) with new gloves, and another in which the gloves were not replaced (NRG). In the PRG group, gloves were replaced every 2 h during 8 h of processing. Food pathogenic bacteria Escherichia coli, Salmonella species, and Listeria monocytogenes were not found in any samples, including gloves and shucked oysters. However, Staphylococcus aureus (SA) was detected in some samples, and the contamination levels were correlated with the working time and the regular replacement of gloves. SA was not detected on gloves or oysters of the PRG group. However, it was detected in the range of <$15CFU/15cm^2$ to $2.9{\times}10^2CFU/15cm^2$ on gloves after 6 h of continuous work, and from <$15CFU/15cm^2$ to $2.23{\times}10^2CFU/15cm^2$ on oysters after 8 h. These results indicate that the SA contamination in shucked oysters originated from the working gloves, and that replacement of working gloves every 2-4 h will minimize SA contamination in oyster products.

This research analyzed the manual performance of firefighting protective gloves on global markets in order to suggest an evaluation method for firefighting protective gloves wearing comfort. We collected 13 types of firefighting gloves from domestic and international markets (7 types from Korea, 3 types form Europe, 2 types from the U.S and 1 type from Japan). We set the Don-Doff test as a basal requirement for moving toward to further manual performance tests that consist of: ASTM dexterity test, Minnesota dexterity test, Bennett hand tool test and ASTM torque test. All gloves were evaluated in dry and wet conditions, we included eight current male firefighters ($43.4{\pm}7.0yr$ in age, $173.1{\pm}4.4cm$ in height, $79.9{\pm}9.2kg$ in body mass) for the tests. Four gloves (1 Korea, 1 U.S, 1 Germany, and 1 Japan) out of thirteen firefighting gloves passed the Don-Doff test and had great subject preferences. There was no significant difference between dry and wet conditions on the ASTM dexterity test, Minnesota dexterity test, Bennett hand tool test and ASTM torque test. However, Japanese gloves had the greatest score and showed 3-4 times faster completion time on the ASTM dexterity test (p<.05), 1.2-1.5 times faster on the Minnesota dexterity test (p<.05), as fast as the bare hand on Bennett hand tool test (p<.05), and greater performance on the ASTM torque test compared to bare hand. In conclusion, Don-Doff test in wet conditions should be the first step for a mobility evaluation of domestic firefighting protective gloves; subsequently, a comprehensive test assorting ASTM, Minnesota, and Bennett test should be developed as a second step. The current ASTM torque test can be adopted as a third step. This three-step-method for evaluating firefighting protective glove mobility can be expected to expand into surveys of other safety gloves in Korea.

This study investigated the effects of wearing latex gloves with inner gloves on the skin hydration of the hands. Fifteen young males participated in the following three conditions: bare hand (BH), latex glove (LG), and latex glove with inner glove condition (LGIG) at an air temperature of $28^{\circ}C$ with 50%RH. Subjects typed a book for 120 min. The results were as follows. Skin hydration was greater for LG and LGIG than BH (p<.001), but no difference was found between LG and LGIG. Skin hydration showed greater values on the thenar and dorsum compared to the palm for both LG and LGIG (p<.05). Skin hydration on the thenar increased during the typing for LG and LGIG, but on the dorsum, palm and finger maintained after 40 min typing. There were positive relationships between hand skin hydration and hand temperature (p<.05). Subjects indicated 'much warmer' and 'more humid' for the LG and LGIG compared to the BH (p<.001), but no differences were found between LG and LGIG. In conclusion, wearing inner gloves inside latex gloves did not induce a reduction of skin hydration and hand temperature; however, significant differences were found in all measurements between bare hands and gloved hands.

Gloves are very important evidence at a crime scene; specifically, rubber gloves can be found easily at homes. Therefore, crime scene investigators attempt to develop fingerprints inside the rubber gloves that are discovered, for identifying unknown suspects. This study compared the effectiveness of three different methods that are used for developing latent prints on gloves with aging time. These were the powder, cyanoacrylate fuming, and multi-metal deposition I methods. The powder method achieved good results for 1-3 days of aged prints, and the cyanoacrylate fuming method worked well on 2-week-old prints. In comparison, multi-metal deposition I method developed good quality fingerprints for 6 weeks of aging time.

In order to evaluate performance of anti-vibration gloves, it is necessary to measure the transmitted vibration to the hand and the applied forces at the same time while gripping the vibrating handle. In the study a system was developed to measure both the vibration and the forces. The system consists of a measurement handle with eight strain gauges and two accelerometers and a PC-based system with a software for signal processing, evaluation of the hand-transmitted vibration and for control of applied forces in the pre-determined range. The handle was installed on the vibration shaker which is strong enough so as not to be affected by dynamic coupling with the hand-arm. Whole procedure of ISO 10819:1996 to determine the vibration transmissibility of anti-vibration gloves was programmed into the system. As an example of the application, three subjects joined the test to get vibration transmissibilities of 9 anti-vibration gloves where each glove was tested twice a subject. Average and standard deviation of the corrected vibration transmissibility were also calculated. All tested gloves fulfilled criterion for M-spectrum($\overline{TR_M}$<1.0), but one glove fulfilled criterion for H-spectrum($\overline{TR_H}$<6.0),

This study was conducted to analyze the wearing practice and the purchasing characteristics of household rubber gloves in order to obtain the product demands for quality improvement. The effects of wearing time per day and demographic characteristics on those were evaluated. A questionnaire was developed and administered to 494 housewives. Statistical tests such as descriptive analysis, crosstabs, factor analysis, one-way ANOVA, were used to analyze the data. The results indicated that housewives were largely divided into two groups according to the wearing time per day. One group wore gloves more than 3 hours a day, while the other wore less than 3 hours. We found that there were significant differences in the wearing practice and the purchasing characteristics between these two groups. It showed that the quality improvement of household rubber gloves should be achieved in a point of view of the comfort feeling and easiness in wearing and taking off. The housewives showed positive attitude toward pliability and necessity, while negative altitude toward dryness, comfort and mobility in wearing. The household rubber gloves were identified as the necessities which is so familiar and common that only a few of demographic characteristics have effect on.

This survey was conducted to evaluate the microbial contamination level of butcher's shops in Seoul, Korea. For microbial inspections, a total of 584 samples (146 cotton work gloves, 146 utensils and equipments, 154 beef samples, 138 pork samples) were collected from butcher's shops. E. coli and pathogenic bacteria such as Staphylococcus aureus, Yersinia enterocolitica, Listeria monocytogenes, Salmonella spp., and E. coli O157:H7 were tested in the samples. As a result, the level of aerobic plate count (APC) ranged ${\leq}10^4\;CFU/cm^2$ from utensils and equipments, $10^1{\sim}10^9$ CFU/glove from cotton work gloves and ${\leq}10^6$ CFU/g from meat. The APC level of E. coli ranged ${\leq}10^1\;CFU/cm^2$ from utensils and equipments, ${\leq}10^5$ CFU/glove from cotton work gloves, and ${\leq}10^3$ CFU/g from meat, respectively. Staphylococcus aureus was detected in 2 beef samples, 1 pork sample, and 10 used cotton work gloves. Yersinia enterocolitica was detected in 3 beef samples, 1 pork sample, and 3 used cotton work gloves. Listeria monocytogenes was detected in 2 used cotton work gloves. In order to improve the sanitation status of butcher's shops, application of HACCP (Hazard Analysis Critical Control Point) or SSOP (Sanitation Standard Operating Procedure), regular hygiene education, and continuous monitoring for microorganisms will be required.

Objectives: The purpose of this study is to analyze the content of N,N-dimethylformamide(DMF) in polyurethane coated gloves(PU-gloves) and to assess the dermal exposure generated by wearing them. Methods: We analyzed the concentrations of DMF in 12 gloves by EN16778 standard. The samples cut into pieces of about 10 by 10 mm and extracted with methanol in flask in an ultrasonic bath at 70℃. An aliquot of the extract is analyzed with GC-MS. The dose of dermal exposure was calculated by ECETOC TRA consumer 3.1 and compared with derived no effect level(DNEL) for systemic effects due to long term exposure by workers. The extracted amount of DMF by saline solution was compared with that by EN16778 standard. Results: The mean concentration of DMF in PU-gloves was 1,377 mg/kg(range 13~3,948 mg/kg). The concentration of DMF showed significantly differences by packing type, manufacturer, and price(p<0.05). The dose of dermal exposure was 0.0007~0.572 mg/kg body weight/day when the DMF content was 10~4,000 mg/kg. The DMF extracted by saline solution was around 11% for 8 hours. Conclusions: The risk of dermal exposure due to the residual DMF in the PU-gloves was not signifiant. But, the limit of 1,000 mg/kg in PU-gloves can be recommended for international standard and trading systems.
