This study is to help produce highly comfortable and wearable and footwear based on the establishment of basic data for manufacturing elderly footwear patterns and products. For this, a survey of 207 women in their 20s and 60-70s was conducted to identify the wearing of shoes, inconvenience areas, purchase practices and footwear preferences by age group. The results are as follows. First, the average age of the young female group was 22.5 years old, the elderly female group was 68.8 years old, and the average shoe size was 236.3 mm for the young female group and 238.3 mm for the elderly female group. Second, young women wore shoes for a longer time than elderly women, resulting in swollen and numb legs, hardened soles, uncomfortable toes and sore heels. However, elderly women felt more uncomfortable wearing footwear than young women. They suffered pain in the joint area, heal and toe areas as well as had more toe deformations due to aging. Third, all age groups preferred athletic shoes and loafers as well as purchases from footwear brand stores and department stores. The elderly spent more money on shoes, longer time to buy and valued the feeling of wearing, whereas the young considered design first. Fourth, both age groups prefer low-heels and natural leather, the young preferred to wear various types of shoes; however, the elderly are found to desire shoes that are comfortable and stable in both form and wearing.

The purpose of this study is to do an in-depth examination of Korean women in their 30's on the characteristics of their online fashion shopping, clothes-wearing, and presentation. In-depth interview and quantitative analysis were conducted as study methods. Results of this in-depth analysis showed that the factor with the most significant influence in their lifestyle was "childbirth." Childbirth was a major factor during fashion shopping and clothes-wearing. Also the results showed that the reason they used online shopping was for convenience, efficiency, rationality, pursuit of information, variety, and hedonism. In particular, women in their 30's had a higher motivation for efficiency and rationality compared to those in their 20's, and of those women, married working women showed the highest preference for fashion soho malls. Meanwhile, full-time homemakers, who pursued rationality, used open markets to search for fashion items based on price. Furthermore, the factors that women in their 30's considered during online shopping were price, design, purpose or situation for wearing the clothing, respectively. Compared to the women in their 20's, they emphasized recommendation, product properties, credibility, economy more than women in their 20's. Factors such as marriage and childbirth were more influential than occupation. Meanwhile, the factors that women in their 30's considered for wearing and presentation were time, place, and occasion(TPO), which all showed high importance in in-depth interview and quantitative analysis. Other factors were 'suitable image to self' and 'covering up body figure.'

목적: 본 연구에서는 일회용 써클콘택트렌즈(이하 써클렌즈)의 초과 착용으로 유발될 수 있는 자각적 및 타각적 변화와 광투과율의 변화를 알아보고자 하였다. 방법: 3가지 다른 재질(hilafilcon B, nelfilcon A, etafilcon A)의 일회용 써클렌즈를 안질환이 없으며 눈물량이 정상인 20대 20안에게 각각 착용시키고 자각적 불편감, 착용자의 순목횟수, 비침습성 눈물막 파괴시간(NIBUT), 각막에서의 렌즈 중심안정위치 및 렌즈 가시광선 투과율를 렌즈 착용직후와 착용자가 불편감을 호소하여 더 이상 렌즈를 착용하지 못하였을 때에 각각 측정한 후 비교하였다. 결과: 일회용 써클렌즈의 평균 착용권장시간인 8시간을 초과하여 15시간 이상 착용하였을 때부터 착용감 저하를 호소하였으며, 30시간 이상 착용 시에는 대부분의 피검자가 렌즈 착용을 중단하였다. 렌즈 착용중단시점에서 대표적인 자각적인 불편감은 뻑뻑함, 건조감 및 피곤함이었다. 일회용 써클렌즈의 초과착용 시 순목횟수는 착용직후에 비해 증가하는 경향을, NIBUT값은 감소하는 경향을 보였다. 렌즈 착용중단시점에서 렌즈의 중심안정위치는 착용직후에 비해 동공 중심으로부터 벗어나는 경향을 보였다. 이러한 결과는 모든 렌즈에서 나타나는 결과이었으나 렌즈 재질의 종류나 개인에 따라서 자각적 및 타각적인 변화 정도의 차이가 존재하였으며 렌즈의 가시광선 투과도의 변화는 크게 나타났다. 결론: 이상의 결과에서 일회용 써클렌즈의 초과착용 시 감소된 NIBUT값은 건조감과 뻑뻑함을, 가시광선 투과도의 감소는 순목횟수 증가를 유발하는 것으로 생각되었으며 이는 중심안정위치의 이탈과 자각적 불편감의 증가를 야기시키는 것으로 생각되었다. 그러나 개인 및 렌즈 재질의 종류에 따라서 그 정도의 차이가 크며, 이로 인하여 개인에 따라서는 예상치 못한 문제가 발생될 수 있으므로 일일 권장착용시간 준수의 필요성 및 문제점의 교육이 필수적이라 하겠다.

The white color is the main characteristics of the traditional color of clothes. From the historical point of view, the Korean's pattern of wearing Baik-Eui can be found its origin from many people of North-East Asia in ancient time. The beginning of wearing Baik-Eui in Korea was at the age of tribes, and it was delivered to middle age, later on, to modern age near the end of Yi Dynasty. The other charactics of the traditional colors. are summarized as follows: 1. Prefered light color to dark color and light blue was noble and worthy. 2. The kinds of color were not various. 3. Color was native and pure not including grey or other colors. From the economical point of vie, the first thing is that Baik Eui was primitive in ti's color Though some say that wearing Baik-Eui is considered as a kind of worship of the Sun, yet we can also find that the every reason of it is that we had little dyes at that time. Especially the reddish dyeing materials were in short supply, so that had been imported mainly from Japan.

Objective: The purpose of this study was to determine the effect of the difference in mask filters on the respiration rate of healthy people. Design: A randomized cross-over design. Methods: A total of 15 subjects were selected for this study (n=15). After filling out the Physical Activity Readiness Questionnaire, the selected participants abstained from caffeinated beverages and meals 30 minutes before and sat in a chair 10 minutes before stabilizing their breathing. Afterwards, the lung function test was performed 3 times for each mask, and the maximum value was used. The provided masks were Mask Free, Dental Mask, KF80, and KF94. Exhalation was measured for 6 seconds for each mask, and breathing was stabilized by repeating inhalation and exhalation until the next time. Results: In this study, the difference in respiratory function according to the mask type was statistically significant except for FEV1 and FVC (p<0.05). As a result of post-hoc analysis, FVC, FEV1, PEF, and FEF values were significantly lower than those of the control group not wearing a mask (p<0.05). When wearing KF94, FVC, FEV1, PEF25-25%, and FEF were significantly lower than when wearing a dental mask (p<0.05). When wearing a KF80 mask, it was significantly lower in FVC and FEV1 than when wearing a dental mask (p<0.05). In FEV1/FVC, the difference by mask type was not statistically significant (p<0.05), but it was lower than the spirometry standard of COPD patients (FEV1/FVC<0.7). Conclusions: As Now that wearing a mask is essential, it has been confirmed that the mask affects the respiratory rate.Therefore, in the case of healthy adults, it is recommended to rest after wearing a mask if attention deficit or headache occurs. People with low breathing capacity are recommended to have low-intensity activities and frequent rest periods after wearing a mask.

The current bra market and the purchasing behavior of women of the MZ generation in Korea are reviewed in this study. Therefore, basic data for bra product planning for women of the MZ generation are presented by investigating the wearing status and satisfaction. Through online surveys, 272 questionnaires were obtained and were analyzed through frequency analysis, cross-analysis, t-test, and variance analysis. Generation M and Generation Z share digital culture, but, due to age differences, they are compared by generation. There was, however, little significant difference between these groups. In addition, there was no significant difference between groups when factoring for the time of wearing, place of purchase, and material of bras. However, there were big differences between groups depending on whether bras had wires, lace, and their size, especially in body correction items. According to the results, it is pointless to target each generation when making a bra. Also, the young generation consumers are more interested in functionality than in the design compared to 10 years ago. It will improve consumer satisfaction if two different types of bras are produced; one that corrects the body and one that fits well even if the body is less corrected.

목적: 콘택트렌즈를 권장착용시간 동안 착용한 후에 렌즈의 재질에 따라 발생하는 각막부종의 정도를 비교해 보고자 한다. 방법: 안질환이나 약물사용이 없는 성인남녀 43명 77안을 대상으로 하였다. Narafilcon A, HEMA, 실리콘 하이드로젤 재질의 정기교체형 렌즈 3종의 렌즈를 사용하였다. 중심각막두께는 Pentacam을 사용하여 렌즈 착용 전과 8시간 착용 후를 측정하였다. 착용 전과 후의 차이 값으로 각막부종의 정도를 판단하였다. 결과: Narafilcon A, HEMA 재질의 렌즈, 실리콘 하이드로젤 재질의 정기교체형 렌즈의 평균 각막부종은 각각 $2.36{\pm}6.15{\mu}m(Mean{\pm}SD)$, $23.61{\pm}10.71{\mu}m$, $18.25{\pm}8.64{\mu}m$였다. Narafilcon A를 착용한 뒤 측정된 중심각막두께는 착용 전 측정한 중심각막두께와 통계적으로 유의한 차이가 없었다. HEMA와 실리콘 하이드로젤 재질의 렌즈에서 착용 후에 유발된 각막부종은 그 정도에 있어 narafilcon A와 통계적으로 유의한 차이가 있었다. 결론: 정기교체형 실리콘 하이드로젤 재질 렌즈에서 유발된 각막부종의 양은 HEMA 재질의 렌즈에서 유발된 각막부종의 양과 통계적으로 유의한 차이가 없었지만 narafilcon A와는 유의한 차이가 있었다. 따라서 콘택트렌즈 재료의 조성에 따라 권장착용시간을 초과하지 않도록 주의해야 할 것으로 판단된다.

Objectives: This study aims to investigate differences in microbial contamination according to the duration and environment of mask wearing. Methods: Forty-five participants were recruited from workers in an offices, multi-purpose facilities, and a schools. After wearing of KF94 mask for two. four, and six hours, the microorganisms adsorbed on the outer and inner layers of the mask were inoculated on BAP(Blood Agar Plate), Chocolate agar, and SDA plates. The bacterial count (CFUs: colony-forming units) cultured in each plate was measured and analyzed for changes in filtration efficiency. Results: The microbial contamination of masks worn in classrooms, offices, and multi-purpose facilities showed a significant difference depending on the environment (p<0.000). The measured CFUs increased significantly according to the time wearing the mask. The difference between the inner and outer layers of the mask was also significant (p<0.05). However, there was no statistical difference in the filtration efficiency of the masks by duration time (p=0.515). Conclusions: Masks worn by workers in the offices, multi-purpose facilities, and schools showed an increase of microbial contamination with the amount of time wearing the mask. The results indicate that the masks used in daily life may have adverse health effects if they are worn for a long time or reused over several days without the realizing that the masks can be contaminated with biological hazards. Guidelines on the safe threshold time for mask use should be established through further research.
