Purpose: The objective of this study is to compare and analyze the wearing status of refractive error correction devices of elders who reside in a city or in a small town district. Methods: Each of opticians from a small town or a city was selected for the study of wearing status of presbyopia correction device for each residential district in units of percentage. with the analysis of the age and gender distributions of the elders, numbers of elderly members, and the kinds of presbyopia correction. Results: The wearing rate of progressive lens was reduced in reverse proportion to the increase of the age for the people of presbyopia in a twon. Pepople in 60s living in a town perferred to wearing bifocal lens, but people of 50~60s preferred to single vision lenses. However, none of people living in a city who is diagnosed as presbyopia had refractive error correction device, and no one used bifical lenses. The progressive lens was mostly used in the people of 40~50s and using rate of those lenses reduced with the age; and single vision lens had the highest rate of in the 40~50s but no one wore it in the 70s. Conclusions: Among the refractive error correction devices, the progressive lens was most widely worn by presbyopia group who is living in a town or a city. In particular, the refractive error correction devices were most preferred in 40~50s of early presbyopia. The highest preference for the progressive lens in the people with the early presbyopia indicates that the wearing rate of the progressive will be increased in future. Therefore, the opportunity of systematic education on the progressive lens should be increased.

The purpose of this study is to analyze the differences of the lower back pain, fatigue, and Achilles tendon thickness according to wearing and not wearing high heels in order to understand symptoms of musculoskeletal diseases caused by wearing high heels in college students. lower extremity pain fatigue and achilles tendon thickness were measured in high heel wear group (n=19) and non high heels wear group (n=23). Participants' general characteristics and the lower extremity pain, fatigue, and Achilles tendon thickness were analyzed using mean, standard deviation. Differences in lower extremity pain, fatigue, and achilles tendon thickness were analyzed by independent t-test. The results showed that the difference between the participants' lower extremity pain (t=2.28, p=.028), right achilles tendon thickness (t=2.30, p=.027) and left achilles tendon thickness (t= 3.89, p<.001) The results of this study show that convergence approach can be applied as a basis for health problems in the structure and function of musculoskeletal disorders associated with wearing high heels. In the future, follow up observation according to the wearing of high heels in the same subject will be needed.

사람들은 자신이 선호하는 스타일의 의복을 착용하기를 원한다. 하지만 다수의 사람들이 자신의 체형 부위별로 본인이 생각하기에 만족하지 못하는 경우가 많아 실제로는 선호하는 스타일이 아닌 자신의 체형을 커버하는 디자인의 의복을 착용하는 경우가 많다. 따라서 본 연구에서는 정장류 착용 경험이 많고 사회 활동을 많이 하는 성인 여성을 대상으로 신체인지도 및 만족도에 따른 아이템(재킷, 팬츠, 스커트)별 선호스타일과 착용스타일에 어떠한 차이점이 있는가를 살펴보고, 이러한 차이가 나타나는 요인을 분석해 보고자 한다. (중략)

Purpose: The present study was conducted to compare any difference caused by pigmentation in the centrations and movement patterns on the cornea between circle and soft contact lens with identical material and parameters during lens wearing. Methods: Soft and circle contact lenses with identical material and parameters were applied to twenty eyes with normal tear volume for 3 hrs a day during a total of 5 days and then their lens centrations, the moving distances and rotations by repeat blinking were compared. Results: The lens centration beyond the fitting criteria was shown in initial wears of both soft contact lens and circle contact lens. However, the centration of soft contact lens was changed to the pupil center for being suitable to the fitting criteria with longer wearing time. On the other hand, the decentration of circle contact lens in the horizontal direction was still presented even with longer wearing time. The moving distances of soft contact lens and circle contact lens decreased with the expand of lens wearing but were not significantly different between total wearing period and daily wearing time. The rotation of circle contact lens by repeat blinking was significantly different from that of soft contact lens even when the wearing period was extended. Conclusions: We revealed that the lens centration and movement of circle contact lens on cornea were different from those of regular soft contact lens resulting in bigger difference with the expand of wearing period in the study.

이 연구는 성인 편마비 환자를 대상으로 PLS (Posterior Leaf Spring) 착용이 기립 균형에 미치는 영향을 알아보는 것이었다. 신발만 착용하였을 때의 기립조건과 신발과 PLS를 동시에 착용한 기립조건의 평균평형지수가 맨발로 서 있을 때의 기립조건에 비하여 높았다. 그러나 신발만 착용한 기립조건과 신발과 PLS를 함께 착용한 기립조건하에서의 평균평형지수의 차이는 없었다. 따라서 편마비 환자의 기립균형과 관련하여 PLS만을 착용한 효과와 신발만을 착용한 효과를 비교하는 연구가 필요하다.

The aim of the present study was to compare the contrast sensitivity of soft contact lens wearers, spectacle wearers or emmetropia. Seventy myopic eyes and thirty emmetropic eyes aged 19 to 26 years were collected. The myopic group included 48 eyes corrected with spectacle lenses and 22 eyes of them corrected with contact lenses, too: all had corrected vision acuity of 20/20 or better. Spatial contrast sensitivity was measured using the OPTEC 6500 contrast sensitivity view-in tester included the EyeView　 Functional Vision Analysis software at photopic or mesoopic condition. There was no significant difference in contrast sensitivity between spectacle lenses and emmetropes. Myopes corrected with soft contact lenses showed statistical sensitivity losses at 1.5, 12 cycle/degree spatial frequencies. In conclusion, our findings suggest that loss of contrast sensitivity in soft contact lens wearers might be interpreted as evidence for corneal disruption before corneal pathological events occur in contact lens wearers. Contrast sensitivity testing appears to be a useful method for evaluating soft contact lenses.

This study aims to compare chest mobility, diaphragm contraction, and lung capacity when wearing a bra and per breast size. The subjects of this study included 10 adult women who were attending Chungnam B University: 5 women who wear underwear size 75A (group A) and 5 who wear underwear size 85B (group B). The chest mobility using a tape measure, the diaphragm contraction using ultrasound, and the lung capacity was measured using a Pony FX before and after bra wear. The chest mobility and diaphragm contraction were significantly reduced when bras were worn in group A and B. Lung capacity was significantly decreased only in group A. There was no significant difference between the groups. This study suggests that women's bras can have a negative effect on diaphragm movement, chest mobility, and lung capacity.

This study was designed to demonstrate the ability of Texas Eye Research and Technology Center Dry Eye Questionaire (TERTC-DEQ) to examine the distribution of self-reported dry eye symptoms and their diurnal intensity in university students and compare it with McMonnies & Ho DEQ. Two dry eye questionnaires were administered to 46 contact lens wearers and 47 nonwearers. Contact lens wearers scored higher on the TERTC-DEQ (52.2%) than McMonnies & Ho DEQ (6.5%). Non-contact lens wearers also scored higher on the TERTC-DEQ (19.1%) than McMonnies & Ho DEQ (2.1%). Ocular symptoms worsened with progression of time of day in both groups of subjects. This study suggests that TERTC-DEQ provides a first-choice diagnosis tool to obtain a comprehensive assessment of patient's symptoms, especially in comparison with McMonnies & Ho DEQ. The TERTC-DEQ is an efficient screening survey and may be use in dry eye diagnosis of contact lens-related dry eye.
