PURPOSE: This study examined the effects of the low dye taping technique on the static and dynamic balancing ability and navicular bone drop when the low dye taping technique was divided into elastic and non-elastic taping. METHODS: The subjects of the study were 31 volunteers without musculoskeletal disorders. The length (L) and anterior (A), posteromedial, and posterolateral values of the arch in the NO (normal eyes open), NC (normal eyes closed), PO (pillow with eyes open), and PC (pillow with close eyes closed) states were evaluated when barefoot and when Kinesio tape and non-elastic tape were applied. The measurements were analyzed using repeated ANOVA and an independent t-test. Post hoc tests were performed using a Fisher's LSD. RESULTS: A significant difference was found in the arch L and A values using a foot scanner (p < .05). In addition, there was a significant difference in dynamic balance in the three directions (p < .05), and no difference was found in the case of static balance. As a result, non-elastic tape application helps improve the dynamic balance ability and arch of the foot. CONCLUSION: The non-elastic tape technique is helpful for the foot arch function, and there is no difference in the static balance ability between Kinesio tape and non-elastic tape. Nevertheless, non-elastic tape is more helpful for the dynamic balance ability than Kinesio taping.

In this paper, we propose a method to detect contours of a face, eyes, and a mouth of a person in the color image in order to make an avatar automatically. First, we use the HSI color model to exclude the effect of various light conditions, and find skin regions in the input image by using the skin color defined on HS-plane. And then, we use deformable templates and genetic algorithm (GA) to detect contours of a face, eyes, and a mouth. Deformable templates consist of B-spline curves and control point vectors. Those represent various shapes of a face, eyes and a mouth. GA is a very useful search algorithm based on the principals of natural selection and genetics. Second, the avatar is automatically created by using GA-detected contours and Fuzzy C-Means clustering (FCM). FCM is used to reduce the number of face colors. In result, we could create avatars which look like handmade caricatures representing user's identity. Our approach differs from those generated by existing methods.

Strabismus refers to a extra-ocular muscle imbalance that results in improper alignment of the visual axes of two eyes. It may be divided into paralytic and non-paralytic strabismus. Paralytic strabismus is primarily a neurological problem: non-paralytic strabismus is more strictly an ophthalmologic problem. This case report focuses on paralytic strabismus resulting from palsies of the third and the sixth cranial nerves, respectively. Oculomotor nerve palsies result in binocular diplopia with characteristic patterns of strabismus. Oculomotor nerve provides motor and parasympathetic innervation to the eyes. Acquired oculomotor nerve palsies are not uncommon. Injury to the third nerve may result in complete or partial dysfunction. Complete third nerve palsy is manifested by ptosis, dilated pupil, an eye that is deviated down and out in primary position, and limited adduction, elevation, and depression. Patients with unilateral sixth nerve palsy complain of binocular, horizontal diplopia esotropia in the primary position due to unopposed action of the medial rectus and limitation of abduction due to weakness of the lateral rectus. Diplopia is worse in the direction of the paretic lateral rectus muscle. Paralytic strabismus are treated, based on the theory of Oriental medicine. with berbal medicines having gun-bi(健脾), bae-to(培土), gue-pung(祛風) effect of acupuncture around the eyes and etc. We describe a 63-year-old woman with complete the 3rd cranial nerve palsy and a 32-year-old woman with the unilateral 6th cranial nerve palsy who treated with acupuncture and herbal medicines and showed complete recovery.

Purpose: To study the effect of hyaluronic acid(HA), which was widely used in artificial tears, multi-purpose solution(MPS), cosmetics, and drug acting on the musculo-skeletal system, in wettability and comfort of contact lens, we compared HA including lens(+HA) with HA excluding lens(-HA) by clinical evaluation. Methods: During four weeks, the selected 28 university student volunteers who did not have any eye disease wore +HA contact lens on their right eyes, and -HA contact lens on their left eyes, and then compared right eyes to left eyes as control. After prescribing by spherical equivalent calculation, over-refraction by auto-refractometer, and contact lens wearing for two weeks and four weeks, tear evaluation, the anterior of eyes examination, fitting convenience evaluation, surface wetting test, surveys were checked up. Results: Compared with the control group (-HA contact lens), +HA contact lens provided better wetting properties. The amount of released tear in -HA contact lens group became less in four weeks than before, but that in +HA contact lens group showed no significant difference from the initial one. In terms of the redness in eye, there was no significant difference between +HA and -HA contact lens groups. Fitting of +HA contact lens on eye was much easier than the control, -HA contact lens. From the results of survey, comfort, wettability, ease of cleaning, and dryness of eye in +HA contact lens group were generally better than those of -HA group, but redness and contact lens handling showed little difference. Conclusions: The addition of HA in soft contact lens(+HA) may enhance the wettability of lens during lens wearing, resulted in the better comfortable wearing of lens eventually.

Purpose: We report two cases of corneal edema in patients who presented with bilateral blurry vision due to vaporized amines while working in a polyurethane processing plant. Case summary: A 28-year-old male presented with bilateral blurred vision. His work involved solidifying polyurethane liquid and he often found himself exposed to polyurethane heat and gas. Purpose: We report two cases of corneal edema in patients who presented with bilateral blurry vision due to vaporized amines while working in a polyurethane processing plant. Case summary: A 28-year-old male presented with bilateral blurred vision. His work involved solidifying polyurethane liquid and he often found himself exposed to polyurethane heat and gas. On examination, the patient's uncorrected visual acuity (UCVA) was 20/40 (right) and 30/50 (left). A slit lamp examination revealed subepithelial microbullae in both eyes. The central corneal thickness (CCT) was also increased in both eyes, measuring $698{\mu}m$ (right) and $672{\mu}m$ (left). After prescribing 0.5% moxifloxacin and, 1% fluorometholone eye drops for 3 days in both eyes, the UCVA recovered to 20/40 (right) and 20/20 (left). The CCT decreased to $644{\mu}m$ (right) and $651{\mu}m$ (left), and the microbullae improved significantly in the left eye. The second patient was a 34-year-old female who presented with bilateral decreased visual acuity while at work. She worked in a factory that produced car seat filling. Her UCVA was 20/25 (right) and 20/20 (left). The CCT by specular microscopy was $537{\mu}m$ (right) and $541{\mu}m$ (left). On slit lamp examination, both eyes demonstrated bilateral central subepithelial edema. The patient did not attend any follow-up outpatient appointments after the initial presentation. Conclusions: Exposure to vaporized amines such as polyurethane may causereversible corneal toxicityeven without direct contact. Further consideration should be given to ocular safety and protection from amine compounds in the industrial field.On examination, the patient's uncorrected visual acuity (UCVA) was 20/40 (right) and 30/50 (left).

The purpose of this study was to make an analysis of the impact of the DRG payment system on medical care pattern and cost of cataract surgery in a general hospital. The subjects were 173 patients whose DRG severity grade was zero, selected from among the hospitalized who underwent cataract surgery before and after the joining to the demonstrational operation of the third year DRG payment system. Their medical records and the details of their medical bills were examined to find out the length of hospital stay, medical care pattern provided to them, the cost of medical care, and the quality of medical care. The length of stay and the amount of medical care supplied during being in hospital dropped significantly for both single-eye and double-eyes cataract surgery groups. The amount of antibiotic use went down during the hospitalization and upon discharge from the hospital, but decreased after discharge. The total medical bills and the rate of basic examination implementation increased in the OPD before hospitalization but after discharge dropped. For double-eyes cataract patients, the rate of double-eyes cataract surgery went down. The total medical bills of DRG payment system converted into the fee-for-service system was greater by 113.3% for the single-eye cataract surgery group and by 102.9% for the doble-eyes cataract surgery group, compared to that by the fee-for-service. The contribution shared by the insurance corporation increased for both single-eye and double-eyes cataract surgery groups, but the copayment by the insured went down. Regarding the treatment outcome, no difference was found in complication rate, resurgery rate and mortality rate before and after the joining to the DRG payment system was implemented. The use of special lens lessened significantly. The amount of medical care supplied during hospitalization decreased but the complication rate didn't increase. But the increased use of low-price artificial cataract and the avoidance of double-eyes cataract surgery was observed. The phenomenon decreased number of OPD visit and the decreased total medical bills of OPD care after discharge in this hospital required further evaluation.

Purpose: This study is research of the conditions which causes difference between the refractive power of the measurement of autorefractometer and the prescription using phoropter. Methods: Autorefractometer (SR-7000) and phoroptor (AV-9000) were used to measure 60 eyes of 30 participants who had no eye diseases and wore the corrective lens due to Ametropia. To prevent the dependence of the prescription value of the refractive power on the testers, two testers measured the refractive power of the eyes of the participants at the same measuring conditions. Results: Statistically, the prescribed values of the refractive power by two testers were not significantly different. Most of the prescribed values of the refractive power were smaller than the refractive power by autorefractometer In case of myopic eyes, the difference between refractive powers by the measurement of autorefractometer and the prescription using phoropter showed the trend of increase as the spherical refractive power became larger. The result was analyzed by the range of the different cylindrical refractive power for the myopic astigmatic eyes. In this case, the difference between refractive powers showed the trend of decrease as the cylindrical refractive power became larger. Conclusions: No difference between the prescribed value by two testers was observed. In case of myopic or myopic astigmatic eyes, the difference between refractive powers by autorefractometer and the prescription were measured to be approximately proportional to the refractive powers of ametropic eyes. As the this difference become larger for the participant who needs the lens of larger refractive power, additional caution is needed in the prescription of the refractive power of the corrective lens.
