  • 미 육군은 다수의 새로운 체계와 기존 차량의 성능 개선을 위해 타이타늄을 평가하고 있다. UDLP(United Defence Limited Pantnership)에 의해 개발된 AGS(The Armored Gen System)는 타이타늄 부가장갑을 사용하고 있다. 아마도 최대의 성능개선 계획은 방호력이 증대된 확장형 M113 인원 수송 차량(APC, 전 세계에 60,000대 이상 배치 운영 중)일 것이다. 측면 방호력 증대를 위해 1.25인치 두께의 부가 장갑판과 전면장갑으로 2인치 두께 판이 고려되고 있다

  • In order to secure safety and improve work efficiency of forest firefighting crews, performance evaluation criteria for safety gloves were developed. Since the standard for forest firefighting safety gloves is not available in Korea, we started the study based on the standard for firefighting safety gloves operated by KFI. 12 test items were selected excluding 5 test items out of the 17 test items through the consultation of stakeholders and the review of foreign standards. Two types of general safety gloves used by forest firefighting crews and one firefighting gloves were tested by applying KFI standard and the results were compared. Materials such as nylon or polyurethane which are weak to fire are not suitable for forest firefighting safety gloves. We compared the criteria of KFI, ISO 16073, NFPA 1977, NFPA 1971 and BS EN 659, and finally selected 12 test items and acceptance criteria suitable for the work environment of forest firefighting crews in Korea.

  • Use of a glove made of materials with a low elasticity decreases the performance of the hand such as agility, dexterity, range of motion, and grip strength. The present study examined if the adverse effects of a low-elastic glove can be reduced by a design which accommodates the changes of hand surface lengths by hand motion. Two glove designs which provide patches of elastic cloth and pleats at the finger joints and knuckle were developed by considering the hand surface length changes, and then compared with two conditions(bare hand and conventional glove design that does not consider the dynamic characteristics of the hand dimensions) in terms of completion time in peg board insertion task, maximum grip strength, discomfort in hand motion, discomfort in force exertion, and overall discomfort by 24 right-handed participants. The test results confirmed that wearing of a glove significantly reduced the agility and grip strength capability of the hand and indicated that the novel designs were effective to lessen the performance decreases compared to the conventional design. Also, of the glove designs, the pleat glove design was found most preferred for both better hand performance and less subjective discomfort.

  • 국내에서 사용중인 농약에 대한 농민의 농약 노출량 및 양상을 조사하고자 내분비계 장애 물질로 추정되는 Mancozeb의 살포 시 작업자의 피부 노출량 및 호흡 노출량 측정을 감귤농장에서 실시하였다. 피부노출 측정은 Patch법(50$\textrm{cm}^2$)을 사용하였고 손 노출은 순면장갑을 사용하였다. 호흡노출은 XAD-2 resin 흡착제와 Personal air monitor(2L/min)를 이용, 측정하였다. Mancozeb 분석은 CS$_2$법을 이용하였고 patch, resin, 장갑, 마스크, 소변에서 Mancozeb의 회수율 및 포장회수율 모두 90%이상이었다. 감귤 재배시 Mancozeb 사용에 따른 피부노출량은 여자가 약 1800mg/hr, 남자는 약 1300mg/hr 이었고 주로 배, 등, 상박 그리고 허벅지에 노출량이 많았다. 호흡노출은 관찰되지 않았고 소변에서도 Mancozeb는 관찰되지 않았다. 위해성 평가를 위해 PDE, AQE 및 MOS를 구하였으며 MOS는 Severn의 공식을 이용하였다. MOS는 여자가 0.37, 남자가 0.58이었다.

  • Recently, economic growth in the world has increased interest in healthy life, and the smart health care industry is growing. In the field of smart healthcare, wearable-type biometric information measurement technology has been highlighted due to the importance of IoT technology. The purpose of this study is to develop a wearable heart - rate monitoring system that can be applied to wearable health care and glove - type monitoring that enables convenient monitoring of heart rate during activity. For this purpose, a glove - type wearable health care system was developed and its performance was evaluated. Experimental results showed that the heartbeat monitoring was possible even in the presence of actual daily activities.

  • This study aimed to investigate the evaluation of firefighting gloves and the behavior regarding their usage, of firefighting officials in Seoul, using a questionnaire. Responses from a total of 270 firefighters who are responsible for putting out fires or undertaking rescue works in Seoul were analyzed. As per the findings, the firefighters considered ease of hand operation and fire/flame protection as the most important performance factors for firefighting gloves, and they were satisfied with the supply status of the gloves. The average number of firefighting gloves currently owned by the firefighters was 2.6 ± 0.8 pairs. Thirty-nine percent of the respondents said that their firefighting gloves lasted, with maintained performance, for more than six months and less than a year, and when asked how they handled the gloves with degraded performance, 46% of them said that they would discard them. Sixty-eight percent of the respondents said that they used the most recently developed and supplied gloves, which they considered as the most satisfying gloves and which they mainly used these days. Respondents were highly satisfied with the fire/flame protection performance of their firefighting gloves, but were less satisfied, however, with the glove fit. These results suggest that there has been a significant improvement in the overall performance level and supply status of the firefighting gloves. Given the current situation, careful considerations with flexible approaches are needed on the current firefighting gloves size system as well as on the personal protective equipment maintenance and management scheme.
