This study analyzed the attitude and effect of middle-age women on wearing girdles. Through this examination, we investigated types of girdles worn by middle-age women and compared and analyzed characteristics among types. By identifying middle-age women's need to wear girdles, this study enables effective development of girdles for middle-age women. Middle-age women's types of wearing girdles were analyzed according to three types of women wearing girdles: hate type, wearing preference type and inconvenience acceptance type. The hate type woman is frustrated with wearing a girdle because it impedes blood circulation, digestion, and causes fatigue. The wearing preference type woman wears a girdle to feel psychological satisfaction and self-confidence and thinks that wearing a girdle pushes the abdomen and supports the hip (hip-up effect). Women strongly agreed that body shape is made beautiful and the silhouette of the lower body is made beautiful by wearing a girdle. The inconvenience acceptance type of woman thinks it is inconvenient to wear a girdle, but nevertheless is satisfied with wearing a girdle. Based on findings of this study, development of girdles considering body shapes of middle-age women, development of soft materials and improvements facilitating dressing methods are needed.

This study was conducted to investigate the immediate effects of abdominal pressure blet on limited of stability and gait parameter in patients after stroke. Thirty stroke patients were recruited to measured pre and post wearing the abdominal pressure belt. The assessment measured limited of stability and spatiotemporal gait parameter. This study result were significantly increase in paretic side area, non-paretic side area, forward side area, backward side area (p<.05) and cadence, gait velocity, stride length (p<.05). This study found that abdominal pressure belt had an immediate effect on improving balance and gait function in stroke patients. Future studies require studies of efficient abdominal pressure levels and intervention periods to improve the balance and walking function of stroke patient.

In this study, the exoskeleton orthosis for the assistance of dorsiflexion torque in ankle joint to prevent foot-drop was developed. It was consist of three part; 1) the power part using artificial pneumatic actuator, 2) wearing part of ankle and knee joints to fix the orthosis, and 3) control part to detect the gait phase using physiological signal. The dorsiflexion torque was generated by the artificial pneumatic actuator connected with wearing part between ankle and knee joint. The accurate timing to assist dorsiflexion torque is made up of physiological signal in foot sole part that detect the gait phase, that is, stance and swing phase in each foot. We conduct the experiment to investigate the effect of exoskeleton orthosis to the 7 elderly people and 10 healthy people. The result showed that the muscular activities in tibialis anterior muscle were reduced because of the assistance of dorsiflexion torque in ankle joint using the exoskeleton orthosis.

Knee sleeve has been used for prevention of sport injuries as well as rehabilitation. To investigate prevention of sport injuries of knee sleeve, it is important to evaluate balance associated with proprioception. The aim of this study was to evaluate the effects of a knee sleeve with a pad that stimulate to golgi tendon organ (GTO_PAD) on proprioception and balance ability. Five healthy males were participated for the study. They were asked to reenact target angle with Biodex and perform one leg standing with knee sleeve and knee sleeve with GTO_PAD. There was no significant difference in %Target angle, but the value of %Target angle was higher in subjects wearing knee sleeve with GTO_PAD than only knee sleeve, except for one subject. During one leg standing, time duration was increased in subjects wearing knee sleeve with GTO_PAD. The length of center of pressure in x-axis (COPx) and COP in y-axis (COPy) were decreased when wearing knee sleeve with GTO_PAD (COPx : $162.06{\pm}58.99mm$ in knee sleeve vs. $149.03{\pm}45.30mm$ in knee sleeve with GTO_PAD, COPy : $310.79{\pm}115.89mm$ in knee sleeve, $291.57{\pm}76.53mm$ in knee sleeve with GTO_PAD). There was significant differences in INI_transition, steady, and LAT_transition phase (all, p < 0.05). These findings support that wearing knee sleeve with GTO_PAD might enhance proprioception and balance.

고지대에서 개최되는 국제운동경기의 경우에 선수들의 고지대 적응이 경기 력에 큰 영향을 미치는 경우가 많다. 고지대에서의 경기는 선수들에게 현기 증을 일으키고 호흡, 순환계의 곤란을 유발시키며, 피로감을 증대시킨다. 국 내에서는 1983년 멕시코 세계 청소년 축구대회 당시 고지적응훈련의 일환으 로, 국내에서 마스크를 착용하고 연습한 사례가 있었다. 이 훈련방법은 정신 력 강화라는 심리적 측면에서 효과가 있을 수 있으나, 일반적으로 고지에서 2-3주간을 지속적으로 체류한 후에 순응이 일어난다는 사실과, 순응된 기능 이 저지대로 돌아올 경우 단시간내에 회복된다는 점을 감안할 때, 연습 시에 는 마스크를 착용하는 훈련방법이 동정맥산소교차의 감소로 저산소증을 유 발하는 고지상황에서의 호흡문제를 해결하는 데는 유효하지 않은 것으로 판 단되었다. 따라서 효과적이고 경제적인 고지적응 훈련은 인간기능에 관련된 변수들의 연관관계를 체계적으로 파악하고, 이 변수들을 효과적으로 조절하 여야만 가능할 것으로 평가되었다.

The purpose of this report was to study visual effect and functional effect of waist line location of slacks for females in 20'. 1. Differences of visual effect of slacks waist line change to be expressed that mature, sexual and casual slacks waist line were W4 or W5, looks like long leg and mature and formal slacks waist line was W1, slim lower part of the body and flat slacks waist line was W4. 2. Analysis result of functional effect difference with the location variation of slacks waist line were as follows. In all motions(M1, M2, M3, M4) W2 that downed 7cm-6cm-6cm from natural waist line was valued as the most comfortable, W1 and W5 were valued as discomfortable, where waist line was too high or too low.

Since radon is an inert gas and is a monoatomic molecule, the size of one particle represents the size of an atom, which means that it has a radius of approximately 1 to 100 nm. Therefore, if the mask has a radius smaller than the size of general fine dust and ultra fine dust, but it is possible to block the inhalation of radon more than a certain amount, it is considered that the exposure through the inhalation of radon can be reduced through normal indoor wear. Accordingly, we would like to find out the radon blocking effect of a mask worn in everyday life. Looking at the reduction rate of radon for each mask, cotton masks decreased by 33.45%, medical masks by 33.50%, KF 80 masks by 35.12%, and KF 94 masks by 37.72%. It was found that the radon blocking effect of the cotton and medical masks was somewhat inferior to that of the KF mask, but the difference was not so great that the introduction of radon into the air could be blocked to a certain level by wearing a mask.

330 Korean adult women were examined the correlation between degree of makeup and makeup satisfaction before/after wearing masks due to COVID-19 and the moderating effect of mandatory/voluntary goal-oriented attitude toward makeup. The study found that lip makeup(p<.001) was significant variable in makeup satisfaction before COVID-19, and eyebrow makeup(0<.002) was significant after COVID-19. Although moderating effect of mandatory goal-oriented attitude, which works between degree of makeup before/after COVID-19 and makeup satisfaction was not significant, but moderating effect of voluntary goal-oriented attitude appeared to be significant before(p<.000) and after(p<.000) COVID-19. And the degree of makeup after COVID-19 was lower than before(p<.000). If one believe that makeup is for one's own satisfaction, degree of makeup can be significant effect on the makeup satisfaction, but actual behavior has shown that degree of makeup has decreased since wearing masks because of COVID-19. I hope this research will be used as marketing material for beauty and cosmetics industry.

In this paper, we evaluate structural integrity of the wearable robot by using finite element analysis, which is made of CFRP(Carbon Fiber Reinforced Plastic) composite materials to be lightened. On the basis of the ASTM(American Standard Test Method), mechanical tests of the material are carried out in tensile, compressive and shear test for analytical evaluation. With the tested composite material, the main frame and two femoral frames of the robot is redesigned to satisfy the lightening design requirements. It is verified with the structural analysis that the redesigned frames are good for the part of the wearable robot.

Purpose: To analyze and compare differences between single vision lenses and functional progressive addition lenses and improvement to binocular visual function wearing functional lenses for pre-presbyopes altered their single vision lenses to functional progressive addition lenses with low addition. Methods: Healthy 32 subjects aged 24.03${\pm}$1.87 (male 23, female 9) who were recruited from university students wore functional progressive addition lenses (EYE-T, Chemilens Co., Korea, ADD 0.750) for 2 months. Objective refraction, corrected visual acuity at distance and near, near point of convergence, near point of accommodation, accommodative facility, phoria at distance and near were measured. And subjective satisfaction was investigated by using a questionnaire designed to fatigue, comfort, discomfort, overall satisfaction and preference. Results: Functional progressive addition lenses were better than single vision lenses at near point of convergence and accommodation, accommodative facility. Exo phoria measured at distance with single vision and functional progressive addition lenses. Exo phoria measured at near with functional progressive addition lenses was higher than that with single vision lenses. As a survey, the satisfaction was increased in questions related near work. However, single vision lenses were preferred in distance test of overall satisfaction, easy 10 adapt, lime to adapt. A survey showed thai preference of functional progressive addition lenses were increased 75.00% to 81.26% for near work, 50.00% to 65.63% for visual fatigue, 47.75% to 50.00% for visual comfort and 31.25% to 46.88% for overall comfort. Conclusions: Comparing between single vision lenses and functional progressive addition lenses, binocular visual function related near work, subjective satisfaction and preference was improved after wearing functional progressive addition lenses. This study suggested that functional progressive addition lenses were useful for long time near work.
