Purpose : To investigate a disposal method of disposing contact lenses and the recognition of environmental pollution by micro plastics which may be caused by the wrong disposal method of domestic contact lens wearers. Methods : Two hundred sixty one adults(124 males, 137 females, mean age $21.48{\pm}3.14years$) were participated in this study. They were given the questionnaire survey on contact lenses purchasing place, type of contact lenses, duration of wearing contact lenses, the disposal method of disposing contact lenses and the recognition of the occurrence of environmental pollution. Results : It appeared that eyeglass shop(50.0%) and contact lens shop(48.3%) were the main purchasing places, and the most common type of contact lenses were disposable lenses(38.5%) and daily wearing lenses(52.5%). On the duration of wearing contact lenses they answered more than 5 years(29.3%), less than 1 year (26.0%), less than 1 year to less than 3 years (26.0%), and on wearing a contact lens during a week they did 1-2 days (32.0%), 1 week (28.0%), 5-6 days (22.4%) and 3-4 days (17.6%). It was shown "no(78.3%)" and "yes(21.7%)" to the questionnaire of whether they received information or education about a disposal method at the place where the contact lens was purchased, and "no(87.5%)" and "yes(12.5%)" to the questionnaire of whether they received information or education from schools, public institutions or public media such as the internet. As for the disposal methods, landfill waste(45.6%), recycled garbage(29.6%), and drainage(16.8%) from the sink or toilet responded in order. Although men were more educated and informed about disposal than women (t=3.63189, p<0.00001), women were more aware of environmental pollution(t=2.44269, p=0.01605). Conclusion : In order to reduce the environmental pollution issue caused by the contact lens which does not decompose at the sewage treatment facility and become micro plastics, it is urgent to provide information about correct disposal methods after using contact lenses and to educate contact lens wearers.

We intend to analyze reasons for low acceptability of protective clothing in pesticide-spraying farmers in Korea, and to use the information for designing new clothing with better acceptability. To understand the attitude of farmers toward wearing protective clothing during spray, a survey was performed on 256 farmers. It is evident that the stress, which is caused by inadequate body temperature regulation, and its accompanying physiological responses are two of the leading factors for the low acceptability of protective clothing. Although the cost of clothing is not an important factor currently, low cost clothing is desirable in the future. Fancy of design is unimportant for new clothing. The results are discussed in conjunction with a desirable research focus for new types of protective clothing. Efforts should be made to ameliorate thermal stress through protective material development and garment design.

상지 절단 장애인들을 위한 미관형 의수는 95% 이상의 시장 보급률을 보인다. 하지만 외부 형상 향상에만 연구 초점이 맞추어져 있어 많은 장애인들이 의수를 착용할 때 차가운 표면으로 인해 이질감을 느낀다. 이로 인해 의수 제작 업체 및 절단 장애인들은 착용 시 이질감이 적은 의수의 보급을 희망하고 있다. 그러므로 본 연구에서는 인체와 유사한 온도를 발생시켜 이질감을 감소시키는 의수를 개발하기 위해 유연 기판인 TPU (Temperature Polyurethane)와 PET (Polyethylene terephthalate) 위에 상용 silver nano paste를 3D 프린터로 인쇄하였으며, UV 표면처리를 사용하여 단시간 내에 낮은 저항과, 높은 회로 접착강도를 갖는 회로를 개발 하였다.

본 연구의 목적은 후프(hoop)의 기원 및 변천과정을 고찰해보고 시대별로 후프의 유형을 분류한 후, 포스트모더니즘 이후 더욱 다양해진 후프가 현대패션에서 어떻게 응용되고 있는지를 살펴봄으로써 후프의 역사적ㆍ미적 가치를 재인식하여 오늘날 복식디자인에 창조의 영감을 줄 수 있는 하나의 모티브를 제시하는데 있다. 후프가 발생하였던 르네상스시대에는 신 중심에서 인간중심으로 사고가 변화하면서, 복식에 있어서도 인간의 신체미를 과시하려는 의도로 인체의 실루엣을 과장ㆍ확대하고자 하였다. 따라서 속옷의 중요성과 역할에 따른 심미적인 기능이 복식에 절대적으로 필요하였고, 뿐만 아니라 기교적인 면에서 속옷에 요구되는 장식성은 어느 시대보다 절실하였다. 그 결과 겉옷이 확대되고, 이에 따라 속옷도 인체를 크게 보일 수 있는 후프가 고안되었다. 후프는 스커트를 부풀리기 위해 철사나 고래뼈 등을 세공하여 만든 테를 넣은 속치마를 말한다. 16세기 중엽 스페인에서 유행한 종형의 파딩게일(farthingale)을 시초로, 영국과 프랑스에서는 드럼형의 휠 파딩게일(wheel farthingale)과 오쓰뀌(hausse col)가 유행하였다. 17세기 초기에는 후프를 착용한 16세기 복식이 유행하였으나, 1625년 이후 슬림한 스타일의 17세기 복식이 유행하자 후프의 착용은 점차 쇠퇴하였다. 18세기에는 파니에(panier)가 유행하여 옆을 부풀린 스커트의 실루엣을 형성하였고, 19세기에는 크리놀린(crinoline), 벗슬(bustle)이 유행하였다.

Recently, in order to prevent the proliferation of COVID-19, which began in earnest in 2020, an increasing number of places have been measuring the temperature and required to wear a mask. However, as wearing a mask and checking the temperature are typically measured directly by a person or by a single individual positioned in front of the machine, standards may vary based on the person's manual measurement method, wasting workforce. While standing in front of a device often measures the maximum temperature of the face, the standard of fever is also unclear. Both approaches can create bottleneck situations when checking large numbers of people. Furthermore, it is unable to conduct periodic measurements and tracking because the measuring machines are generally put only at the entrance. Thus, this study suggests a method for preventing the spread of infectious diseases by automatically identifying and displaying unmasked people and those with fever in real-time using a general camera, a thermal imaging camera, and an artificial intelligence algorithm.

Safety helmets are used widely in various industries by workers since they are legally required to wear them. However, thermal discomfort is one of the major complaints from helmet users. To relieve this problem, frozen gelled packs can be considered for use inside the helmets. In this paper, tests were performed on humans to evaluate the physiological strains of wearing safety helmets and to investigate the effects of using frozen gelled packs inside the helmets. Experiments were conducted in a climatic chamber of WBGT $33{\pm}1^{\circ}C$ under four differed experimental conditions: 1) not wearing a safety helmet(NH); 2) wearing a safety helmet with frozen gelled pack A(HA); 3) wearing a safety helmet with frozen gelled pack B(HB); and 4) wearing only a safety helmet(OH). The results were as follows. First, when comparing NH with OH, physiological responses such as $\bar{T}_{sk},\;T_r$, HR and sweat rate were significantly higher in OH and subjective sensations were reported as less hot and more comfortable than NH(p<.05). Second, in regard to the frozen gelled packs inserted inside the safety helmets, some physiological responses in HA were different from those in HB, according to the two different types of packs. HA was hotter, more uncomfortable and less exhausted than HB. However, result from both HA and HB were lower than those from OH in terms of temperature and humidity inside safety helmet, sweat rate, $T_r$ increase, heat storage(p<.05). When wearing safety helmets with frozen gelled packs, it was shown that heat strain can be alleviated. These results are expected to help millions of workers who complain that wearing safety helmets is uncomfortable and messy.

The results of analyzing the outfits of male and female characters depicted in the "Hoehonryedocheop" (回婚禮圖帖, Deoksu 6375) held by the National Museum of Korea and estimating its production date of the "Hoehonryedocheop"are as follows. Firstly, an elderly groom is depicted wearing a patterned heukdanryeong (黑團領) with rank badges, a garment commonly donned by government officials in works such as "Jeonanryedo (奠鴈禮圖)" and "Gyobaeryedo (交拜禮圖)". And the old groom in "Heonsuryedo (獻壽禮圖)" "Jeobbindo (接賓圖)" and "Jungroeyeondo (重牢宴圖)" is shown wearing a jarip (purple hat) without a paeyoung (ornamental jewelry strap), accompanied by jade colored robe with a red strap belt. Gireokabeom (雁夫) is observed wearing a jarip (紫笠) adorned with a paeyoung (貝纓) and a patternless heukdanryeong with rank badges. Adult male descendants are depicted wearing dopo (道袍), while guests wear dopo, cheolrik (帖裏), and jikryeong (直領), accompanied by red and blue straps denoting their social status. Jingssi (徵氏), sidong (侍童), and young grandchildren are observed wearing jungchimak(中赤莫). The young servants are wearing jungchimak, and the boys carrying the food have braided their hair and worn sochangu (小氅衣), while adults servants wore jeonrip (氈笠) and sochangui. Performers are seen clad in a sochangui, jeonbok, and a blue sash around their waists. Secondly, the elderly bride is portrayed wearing a keunmeori (ceremonial headdress) and a green wonsam (圓衫) in "Gyobaeryedo," while in "Heonsuyeondo," she is depicted in a blue skirt and a jade colored jeogori (赤古里). Women descendants are shown adorning headdress decorations, such as binyeo(簪), banja(斑子) and pearl daenggi (眞珠唐紒) on their eoyeomeori (於于味, ceremonial headdress). They are further dressed in skirts of navy, red, and jade hues, paired with various-colored jeogori. Additionally, a woman wearing a navy skirt and a green jangot (長衣) is also depicted. The dongnyeo (童女, unmarried women) wear beolsaengmeri (娘子雙髻), headdress) with long binyeo and long dodaik-daenggi (都多益唐只). They wear chilbo-jokduri (七寶簇頭里) and a red skirt with a green hoejang-jeogori (回裝赤古里). Bija (婢子) wears garima (加里亇) on her eoyeomeori and is seen dressed in skirts and jeogori resembling those worn by noble women, albeit with lighter colors, shorter skirt length, and a subdued volume. Ginyeo's attire bears similarities to that of noble women, although with a dress with less vibrant tones and devoid of decorations on the eoyeomeori. Thirdly, based on the main character's jarip, along with the cheolrik and jikryeong worn by the guests, as well as the performances by musicians of the military camp, it is suggested that the main character of the 60th wedding anniversary is connected to the Ministry of Military Affairs or the military camp. Judging by the military band's short-sleeved vest, the silhouettes of the women dress, and the headdresses, it is likely that the "Hoehonryedocheop" was produced between the 1760s and 1780s.
