목적: 본 연구에서는 동일 재질 및 렌즈 파라미터를 가진 일반 소프트 콘택트렌즈와 써클 콘택트렌즈의 각막에서 중심안정위치와 움직임 양상을 비교하여 착색 여부에 따른 차이를 알아보고자 하였다. 방법: 눈물양이 정상인 20안을 대상으로 동일한 재질 및 파라미터의 일반 소프트 콘택트렌즈와 써클 콘택트렌즈를 각각 1일에 3시간씩 5일 동안 착용시키면서 각막에서의 중심안정위치와 반복적인 순목 후 콘택트렌즈의 이동거리 및 회전량을 측정하고 비교하였다. 결과: 일반 소프트 콘택트렌즈와 써클 콘택트렌즈 모두 착용 초기의 중심안정위치는 피팅 기준에서 벗어나는 경우가 있었으나 일반 소프트 콘택트렌즈의 경우는 착용 시간이 증가함에 따라 동공 중심으로 모이면서 모든 경우에도 피팅 기준에서 벗어나지 않는 적합한 중심안정위치로 변화되었다. 하지만, 써클 콘택트렌즈는 착용 시간이 증가하여도 수평 방향으로의 중심이탈이 여전히 존재하였다. 일반 소프트 콘택트렌즈와 써클 콘택트렌즈 모두 반복적인 순목 후 각막에서의 이동거리는 착용기간이 증가할수록 감소하였으나 두 콘택트렌즈 간에는 총 착용 기간이나 일일 착용 시간의 증가에 따른 차이는 통계적으로 유의하지 않았다. 반복적인 순목에 의한 써클 콘택트렌즈의 회전양은 착용기간이 증가하였을 때 일반 소프트 콘택트렌즈를 착용한 경우와 비교하여 통계적으로 유의한 차이가 있었다. 결론: 써클 콘택트렌즈의 각막에서의 위치 및 움직임은 일반 소프트 콘택트렌즈와 달라지며 이러한 차이는 착용기간이 증가하면 더 커짐을 밝혔다.

A whole-body compression garment (WBCG) is mainly used for cosmetic purpose in Korea. Another case for wearing the WBCG would be while exercising because it allows the body to move easily. But physiological effects of wearing WBCG to the body have not been known much. To investigate whether wearing WBCG would be helpful for conducting exercises, we measured physiological criteria, which could be influenced by the compression, such as cardiovascular and pulmonary function. Twelve female college students participated in this experiment. Increase of blood pressure was monitored in all of the participants when they wore a WBCG just for 10 minutes. Pulmonary function that requires skeletal muscle contraction was decreased by wearing a WBCG. Blood pressure measured after conducting exercise became even lower when wearing a WBCG than non-wearing. Interestingly, heart pulse remained lower when wearing a WBCG than non-wearing during the whole relaxing period after the exercise. Electrocardiogram (ECG) analyses showed that such lower heart rate largely depended on extension of QT time. For that reason, physiological efficiency index (PEI) was higher for wearing WBCG. These results indicate wearing WBCG could enhance exercise efficiency by lowering heart pulse.

The children who are part of this study are compelled to wear masks at educational facilities for an extended period of time as they continue to be exposed to Asian dust, fine dust, and COVID-19. However, use of masks is currently causing them a lot of inconvenience. This study aimed to gather basic data for the development of a mask that is suitable and comfortable for children to wear. A total of 331 children aged 1 to 9 were investigated through their parents in terms of their lifestyle, mask wearing and purchasing status, mask preferences, mask inconvenience, and mask improvement. According to the survey on mask use, the proportion of children aged 1-3 years old and wearing ultra-small/XS masks, 4-6 year olds wearing small/S, and 7-9 year olds wearing small/S was the highest. More than 80% of children were wearing masks with a standard filter of KF80 or higher. The purchase criteria for children's masks were found to be excellent in terms of wearing comfort and meeting the filter standards. According to the survey on inconvenience of wearing masks, the majority of those surveyed expressed the need to develop children's masks of different sizes. Furthermore, they experienced various kinds of inconveniences from adult masks, such as the material quality and length of earring bands; it was deduced that these aspects need to be taken care of. The vertical folding type was the most popular in the mask design for children. Children have to wear masks for a prolonged period of time, but they are experiencing lot of inconvenience, which need to be addressed.

To do this study, we produced cooling vest newly. Rectal temperature was ascended approximately from 37.2$^{\circ}C$ to 38.05$^{\circ}C$ in lab, but wearing cooling vest, the temperature was descended 0.2 while wearing developed product compare with existing product. Mean skin temperature which was showed distribution from 32.8∼36.5$^{\circ}C$, it was descended 1.0∼1.1$^{\circ}C$, while wearing cooling vest and comparing with existing product, wearing developed product was lower 0.5$^{\circ}C$, While wearing developed product, it was found that they had lower tendency than exiting product. Specifically in case of temperature within clothing(chest) 0.2∼2.0$^{\circ}C$ in case of humidity within clothing 2∼8% RH. Facts from above we confirmed that clothing microclimate had been improved and space was happened between body and garment in order to control. In subjective sensation, existing product made negative response during experiment period from participants, but developed product was nearing to comfortable area.

Soek(Xi) was the highest ranked shoe that was worn with the primary formal dress in East Asian countries including ancient Korea and China. This article examined Joseon's Seok as discussed in previous studies, and it explored factors such as the wearers' status, wearing situations, its morphology, its materials, and its colors in the Great Han Empire period (1897~1910), and then extracted three morphological characteristics of the Korean Seok to examine its origin. The results of the study are as follows. For women, the Seok in the Great Han Empire period was worn with Won-sam(圓衫) and No-eui(露衣) as well as Jeok-eui(翟衣), and hence its range of wearing was extensive. Also, red Seok was worn with deep red colored Dae-sam(大衫)-styled Jeok-eui in the Joseon period(1392~1897), and blue Seok with deep blue Jeok-eui in the Great Han Empire period. This suggests the possibility that wearing of deep blue Jeok-eui occurred after 1906 in terms of the use of blue Seok. As for its morphology, its leg-less form was maintained into the late Joseon period, and there were no great changes in its name. The characteristics of the Korean Seok's morphological structure consisted of a shoe leg, the wood-less bottom and pearl ornament. As a result of the examination of the origin of those characteristics, it has been clarified that the form in which Gu, Eok, Jun(純), are attached in the structure with a shoe leg originated from the combination of Hwa(靴) and Li(履) after the two types of shoes were alternately worn in the Song (宋) period. Also, it was confirmed that the woodless bottom appeared between the periods from Wei Jin Northern and Southern Dynasties(魏晉南北朝) to Sui(隋), and the pearl ornament occurred in the Jin(金) period.
