  • Background: Human body is formed of symmetric bilateral structures that are comprised of eye, upper arm, lower arm and etc. but, we are used only dominant components. The purpose of this study was to analysis length cognition ability in dominant eye. Methods: Total 88 persons (male 18, female 70) were participated in this study. They were tested with ‘hole in the card’ test for identification of dominant eye's side, then the length cognition ability was measured in right & left axillary level by describing 10cm line. Results: The results by independent t-test were as follows. In difference of length cognition ability in right axillary level between right dominant eyed group & left dominant eyed group, right dominant eyed group was superior to left dominant eyed group, but significant difference was not existed statistically(p>.05). In left axillary level, right dominant eyed group was superior to left dominant eyed group, but significant difference was not existed statistically(p>.05). Conclusion: These result can be applied to the learning of palpation & observation skill in physical therapy, although this study was not identify a relation between dominant eye & dominant hand.

  • Purpose: The purpose of this study was to examine dry eye syndrome and ocular fatigue according to the status of contact lens wearing and management among female university students. Methods: The subjects were 195 female university students wearing contact lenses. Ocular Surface Disease Index (OSDI) and Virtual Reality Symptom Questionnaire (VRSQ) were used to determine the level of dry eye syndrome and ocular fatigue. The SPSS/WIN 21.0 program was used for analysis of data. Results: Significant differences in the level of dry eye syndrome were observed according to the period of case solution change (F=3.36, p=.037) and the reasons for the change of lens (F=4.56, p=.004). In ocular fatigue, significant differences were observed according to the price of lens (F=3.53, p=.031), rinse in storing lens in a case (t=-2.57, p=.011), and learning about contact lens (t=-2.01, p=.046). A significant positive correlation was observed between dry eye syndrome and ocular fatigue in the subjects. Conclusion: The results of this study show that some subjects have problems in wearing and management of contact lenses. Therefore, an education program related to contact lenses should be provided to contact lens wearers to improve the status of wearing and management of contact lenses.

  • In the naked eye observation, the health of livestock can be controlled by the range of activity, temperature, pulse, cough, snot, eye excrement, ears and feces. In order to confirm the health of livestock, this paper uses calf face image data to classify the health status by image shape, color and texture. A series of images that have been processed in advance and can judge the health status of calves were used in the study, including 177 images of normal calves and 130 images of abnormal calves. We used GLCM calculation and Convolutional Neural Networks to extract 6 texture attributes of GLCM from the dataset containing the health status of calves by detecting the image of calves and learning the composite image of Convolutional Neural Networks. In the research, the classification ability of GLCM-CNN shows a classification rate of 91.3%, and the subsequent research will be further applied to the texture attributes of GLCM. It is hoped that this study can help us master the health status of livestock that cannot be observed by the naked eye.

  • Objectives : There has been a continued debate regarding the role of eye movements in Eye Movement Desensitization and Reprocessing(EMDR). This study examined the possible autonomic effect of horizontal eye movements after being exposed to fearful stimuli. Methods : Fifty two healthy adult women were randomly allocated to eye movement or eye fixed groups after watching a five minute fear-inducing film clip. ECG was recorded during the resting state, after watching the clip, and the treatment. A spectral power analysis of the heart rate variability was performed. As the variables violated the rule of normal distribution and the number in each group is small the non-parametric test was used. Results : Overall, we did not find the differences between the groups in both time and frequency domains. Some minor differences found were not consistent with results from previous studies. Conclusions : Effect of eye movement on autonomic nervous system during fear desensitization was not supported in this experiment. Further study with other psychophysiological measures is needed to understand the role of eye movements in treatment of traumatic memory.

  • Purpose: This study aims to measure the improvement of balanced ability and rapid response of 30 healthy adults by performing dynamic stretching, static stretching, and sargent jump. Methods: The sample 30 peoples without any musculoskeletal disease who volunteered to be the subject of the study. We measured all subjects on following metrics to evaluate the function and stability under the normal condition, with dynamic stretching (DS) group, static stretching (SS) group: vertical jump height and reaching distance Anterior, Posteromedial, Posterolateral and NO (Normal eye open), NC (Normal eye close), PO (Pillow with eye open), and PC (Pillow with close eye) were evaluated. All measures were analyzed using independent t-test and One-way repeated Anova. Results: There was a significant increase in SJH (Sargent jump) in both groups (p<0.05). In Y-balance test, there was a significant increase in both groups except for the ANT (Anterior) direction, and there was a significant increase only in the SS group in the ANT (Anterior) direction (p<0.05). There was no significant difference between the DS group and the SS group (p>0.05). There was no significant improvement in ST (Stability Index) and WDI (Weight Distribution Index) in both groups (p>0.05). Conclusion: Both DS and SS showed significant improvement in SJH and Y-balance tests, which are dynamic functions, but had no significant effect on static balance ability.

  • In an attempt to evaluate working conditions and hazardous environmental factors, a survey on health problems was conducted for 721 employees from 18 industrial plants in Young Dung Po and Sung Dong districts of Seoul in the period from May 1975 to Feb, 1976. The questionnaire and survey was inclusive of all illnesses known as most common to industrial workers (according to the report by Korea Industrial Health Association) of this country and envi ronmental factors pointed out by the workers. The results were as following. 1. The over whelming majority of complaints were psychiatric, ear,eye, and digestive disorders. 2. Those whose work time is the longest have a propotionately higer incidence of complaints especially in eye,ear, neuromusculoskeletal, and neurosensory systems. 3. In females whose occupational history is relatively short, a higher incidence of digestive and skin section disorders was noted and this is especially true among those working in night shift. 4. Among machinery industry workers, most complaints were of eye, ear, and neuro musculoskeletal disturbances, and this fact seems to be closely related to physical over works. 5. Dust and noise were pointed out by the largest number of workers as undisirable conditions in work environment. 6. Distribution of complaints are closely related to the type of industry, and in comparison with the result reported by Korea Industrial Health Association in 1972, the prevalence rates of occupational disorder were similar in our study,

  • Despite considerable interest in the biologic processes of regeneration and stem cell activation, little is known about the genes involved in these transformative events. In a Hydra littoralis model of regeneration, we employed a rapid shotgun suppression subtractive hybridization strategy to identify genes that are uniquely expressed in regenerating tissue. With an adaptor-PCR based technique, 16 candidate transcripts were identified, 15 were confirmed unique to mRNA isolated from hydra undergoing regeneration. Of these, 6 were undescribed in GenBank and allied expressed sequence tag (EST) databases (GenBank + EMBL + DDBJ + PDB and the Hydra EST database). BLAST analysis of these sequences identified remarkably similar sequences in anonymous ESTs found in a wide variety of animal species.

  • A model was developed for a simple clinical trial in which graders had defined probabilities of misclassifying pathologic material to disease present or absent. The authors compared Kappa between graders, and efficiency and bias in the clinical trial in the presence of misclassification. Though related to bias and efficiency, Kappa did not predict these two statistics well. These results pertain generally to evaluation of systems for encoding medical information, and the relevance of Kappa in determining whether such systems are ready for use in comparative studies. The authors conclude that, by itself, Kappa is not informative Enough to evaluate the appropriateness of a grading scheme for comparative studies. Additional, and perhaps difficult, questions must be addressed for such evaluation.
