An outsider's perspective is often illuminating and enlightening, as he or she perceives the world differently from us, and sees things that insiders tend to miss. While an outsider's views are fresh and penetrating, an insider's vision is often banal and myopic. Although outsiders' perspectives may not be quite right at times, they always shed light and provide insight, allowing us to reevaluate the conventional interpretations of our literature and folktales. In order to prevent our own understanding and knowledge from growing stale and narrow-minded, we should endeavor to consider outsiders' opinions and view all things from multiple angles. When reading literary or cultural texts, therefore, we need to read through others' eyes because it provides alternative perspectives. And we should learn to co-exist with others and see things from others' eyes. In his celebrated novel, My Name Is Red, Orhan Pamuk, the Turkish Nobel Laureate, explores the themes of clashes between the East and the West, the young and the old, and conservatism and radicalism. The confrontation between the stubborn defenders of tradition and the self-righteous innovators ultimately results in bigotry, hatred and murder. As Pamuk aptly perceives in his novel, the inevitable outcome of such uncompromising conflict is degradation of humanity and annihilation of human civilization. That is precisely why we need to embrace others who are different from us and learn to look through others' eyes. Sometimes, we fear other voices and different perspectives. As the movie "The Others" suggests, however, there is no reason for us to be afraid of others.

The leaf spring is used in the suspension of most buses and trucks due to its compactness, which reduces the shock-force and the vibration from the road, and increases passenger comfortability and carlife. Of the various kinds of leaf springs, the leaf spring without eyes can be found easily in the heavy duty truck, and has different characteristics to the leaf spring with eyes in the case of large free camber. Because of radius change, the leaf without eyes slips on the supports, which makes the deflection. The difference is due to this deflection. In this paper, we show the general method of characteristic analysis, for example, Pandan method, can be no more applicable to these springs. Thus considering the geometry deflection by slip, we have developed the equation of the characteristic of the leaf spring without eyes and prove the effectiveness of this equation by experiment. From the result, at large camber the slip deflection is large and as camber smaller, this is smaller. At the camber behind some value, the effect of slip no longer influence to the characteristic of leaf springs.

Purpose: Chronic ankle instability is a very common abnormality of the ankle, but there is still controversy regarding its evaluation criteria. The stress view has difficulties in reflecting the patient's symptoms and treatment progress. Therefore, this study examined the relationship between the center of pressure (COP) measured by a pedobarograph and the symptoms of the patient. Materials and Methods: Thirty patients with chronic ankle instability from February to August 2018 were included. Each patient was surveyed with the foot and ankle outcome score (FAOS). The COP was measured with a foot pressure scanner, and the travel distance and ellipse area of the COP were calculated. Each patient was measured on one foot and on two feet with his or her eyes closed and open. The relationship between the COP measurement and FAOS score was analyzed using the Pearson correlation coefficient. Results: The participants were consisted of 21 male and nine female, with a mean age of 30 years, mean weight of 72 kg, and mean foot size of 259 mm. With the eyes open, the correlation coefficient between the FAOS and travel distance of the affected side was -0.394 (p<0.05) and that between the FAOS and the ellipse area of the affected side was -0.425 (p<0.05). On the other hand, no significant correlations were found between the travel distance and ellipse area of the affected side when patients closed their eyes. Conclusion: Measurement of the COP using foot pressure scanner could evaluate objectively patients with chronic ankle instability, with measurements in patients with their eyes open being more significant. Based on the findings of this study, an analysis of the COP with the patients with their eyes open and standing on one foot may help determine the management strategy and assess the progress of the patients.

Purpose : To evaluate the effect of cervical strengthening exercise on balance ability in healthy adults. Method : The subjects consisted of forty healthy people. The subjects were divided into two group. The control group(n=14) received no exercise and/or stimulation. The cervical strengthening exercise group(n=14) performed therapeutic intervention using cervical exercise for strengthening of cervical spine muscle. The exercise group were accomplished during 6 weeks(2~3set, 5times/week). All tests were completed before and after experiment. The static balance ability was measured by normal standing when subjects open and close their eyes on GOOD BALANCE SYSTEM, respectively. For each case, the experimental data were obtained in 3 items: mean X speed, mean Y speed and velocity moment. Result : The results of this study were as follows; 1. In the exercise group, the statistically significant difference were shown on X speed and Y speed in the case of normal standing when subjects open and close their eyes and X speed, Y speed and velocity moment in the case of normal standing when subjects close their eyes(p<0.05). 2. In control group, the statistically significant difference were not shown on all posture(p>0.05). 3. There were a statistically significant difference in the X speed and Y speed in the case of normal standing when subjects open their eyes between control group and the exercise group(p<0.05). There were a statistically significant difference in the X speed, Y speed and velocity moment in the case of normal standing when subjects close their eyes between control group and exercise group(p<0.05). Conclusion : The above results revealed that therapeutic intervention for muscle strengthening of cervical there were positive changes to balance ability.

The purpose of this study was to compare the static balance of standing position between adolescent idiopathic scoliosis (AIS) and a normal group that were aged-matched. There were forty subjects included in this study. Twenty-seven healthy subjects (age, $13.9{\pm}1.2$ yrs; height, $161.9{\pm}7.5$ cm; weight, $52.2{\pm}7.7$ kg) and thirteen AIS subjects (age, $14.2{\pm}2.2$ yrs; height, $161.5{\pm}8.7$ cm; weight, $48.1{\pm}8.1$ kg) were participated in the study. The thirteen subjects in the AIS group had a major Cobb angle between $20.1^{\circ}$ and $49^{\circ}$. Each group was tested with the Balance Performance Monitor (BPM). The parameters for static balance were sway area, sway path, max velocity, mean balance, anterior-posterior angle, and left-right angle of each group with their eyes opened and again with their eyes closed. Both sides of the forward reach test and the lateral reach test were also performed on each group. Results from the BPM tested showed significantly increases in all parameters of static balance with those patients with AIS under the conditions where eyes were opened and closed. In the right and left forward reach test, there was no significant difference between normal and AIS groups. However, in the lateral reach test with right and left direction, there were significant differences between normal and AIS groups. For the normal subjects, there were significant differences in the parameters with sway path and anterior-posterior sway angle between the eyes opened and closed. However, there were no significant differences in the all parameters between eyes opened and closed for the AIS subjects. These results suggest that, balance programs could be used in the rehabilitation setting for intervention of AIS and evaluation of AIS. Further study is needed to measure many patients with AIS and other functional balance scales for clinical application.

Purpose: This study examined the effect of calf muscle fatigue on postural sway according to foot posture (a pes cavus, a normal foot, and a pes planus). Methods: The subjects of this study were 12, 11, and 9 students of U University with a pes cavus, a normal foot, and a pes planus, respectively, according to a Navicular Drop Test. Postural sway was measured with a balance instrument (BioRescue, RM Ingenierie, France) while the subjects stood static on two legs as well as during one-leg standing using the dominant leg in two conditions (with the eyes open and with the eyes closed for 30 seconds). Muscle fatigue was then induced in the calf muscle of the dominant leg, and both muscle fatigue and postural sway were measured using an EMG. To compare the degree of postural sway between the three groups after muscle fatigue was induced, the change values were calculated. The results were analyzed using a Kruskal-Wallis test, and a post-hoc test was conducted using the Bonferroni correction. Results: Significant inter-group differences were detected for postural sway during two-leg standing with the eyes closed and during one-leg standing with the eyes open and with the eyes closed (p<0.05). The post-hoc test showed significant differences between the pes cavus and normal foot groups and between the pes planus and normal foot groups for all three variables (p<0.05). However, no significant difference was detected between the pes cavus and pes planus groups (p>0.05). Conclusion: The results of this study show that the pes cavus and pes planus cause more fatigue and postural sway than a normal foot. Therefore, attention should be paid to changes in balance caused by muscle fatigue.

Purpose: This paper provides basic clinical data on the treatment of scoliosis patients by analyzing the effects of the type and position of scoliosis on the static balance using Tetrax on adolescents who have balance disorders as a consequence of structural changes, such as scoliosis. Methods: A total of 110 adolescents were divided into 6 groups according to the radiographs and 60 adolescents were sampled, 10 each for each group. The static balance was measured and analyzed on the existence of sight using Tetrax. Results: The changes followed by existence of sight in static balance group showed a significant difference statistically in Stability index in all groups (p<0.001). The changes in the static balance in each group in terms of the stability index were significant in all groups, where the experiments were performed under the eyes opened and eyes-closed condition (p<0.01)(p<0.001). The post-hoc comparison revealed the stability index to be the highest in the eyes-opened condition in group III, but not in group IV. In the eyes-closed condition, group III showed the highest stability index of all the groups. Conclusion: Adolescents with lumbar scoliosis had a lower static balance in single scoliosis with the eyes-closed condition or had little movement compensation. In addition, unlike the other normal scoliosis, back scoliosis has negative effects on the posture because it causes an increase in the disturbance of posture. Therefore, future studied will be needed to examine the imbalance of posture in people suffering from back pain.

A group of 80 Holstein calves, many with clinical signs of infectious bovine keratoconjunctivitis in summer seasons, was assembled for bacteriologic and ophthalmologic studies at an integrated dairy farm. Observations were started from 1980 to 1984 but bacteriological study was only carried out from thor spring in 1981 and continued during the Autumn in 1981. Corneal lesions and drugs sensitivity were also observed and the results obtained were as follows: 1. Occurrences of IBK-affected cattle during the 5 years were predominent to calves in summer. 2. Among 142 eyes from 80 cattle, 53 isolates of Moraxella bovis(37.3%) were isolated from 37 cattle(46.3%). The prevalence of the infection for clinical eyes were higher than nonclinical eyes calves. 3. Miscellaneous organisms were found from age groups of 5 months to 9 months old. It were 8 hemolytic Neisseria spp., 3 Fungi, Mycoplasma sp. and 1 Pseudomonas sp., but 9 samples were unknown. 4. Prevalence of infection with M. bovis in bilateral clinical eyes were higher than unilateral eyes. 5. Incidence of corneal lesion was predominent in early stage as a watery tears(21.0%) and late stage as a leukomas of corneal opacity(22.8%). 6. The number of isolations of M. bovis and incidence of IBK varied from year to year; Higher incidence of IBK clinical signs were showed in calves from 5 months to 10 months old and the number of isolations of M. bovis was declined in order 8 months(100.0%), 4 months(75.0%), 5 months(66.6%) and 8 months(66.6%) old calves. 7. Chloramphenicol, Nitrofurantoin and Cephalothin were highly sensitive against M. bovis isolates and then Tetracycline, Neomycin, Erythromycin and Kanamycin were intermediate but low sensitive to Streptomycin, Colistin and Penicillin.
