  • Purpose: This study was conducted to research effects of influence factors on stereopsis of induced aniseikonia in emmetropia. Methods: 20 college students (a mean age of $22.50{\pm}2.72$ years, 14 males, 6 females) were selected as subjects and all of them had no ocular disease or systemic disease, the refractive correction of spherical equivalent within ${\pm}0.50$ D, the corrected visual acuity of 1.0 or better and the aniseikonia values less than 1% by AWAYA. Subject's dominant eye was checked by Hole in card method and contact lenses of -7.00 ~ +7.00D were fitted to cause anisometropia in dominant eye or non-dominant eye, respectively. And then aniseikonia was induced with spectacles to correct refractive error by contact lenses. Stereopsis was measured by Random Dot Stereo Acuity Test with LEA symbols$^{(R)}$ (Vision Assessment Corporation$^{TM}$, USA). Results: Stereopsis was remarkably reduced by inducing aniseikonia, with induced aniseikonia in dominant eye, with higher diopter of wearing contact lenses to induce anisometropia, with spectacles lenses correction of minus power after fitting contact lenses with plus power and in case of men. Conclusions: It should be considered to correct anisometropia that aniseikonia could cause reduction of stereopsis.

  • Coptidis Rhizoma, Fraxini Cortex, Jinpisan(秦皮散) have been as eye washes of inflammatory eye disease in the oriental medicine. Especially Jinpisan(秦皮散) has been used for the disease which is similar to Peudomonas aeruginisa keratitis. This research was attempted to investigate the effect of Coptidis Rhizoma, Fraxini Cortex, Jinpisan(秦皮散), on Peudoronas aeruginisa keratitis. Pseudomonas aeruginosa keratitis causes a deep rapid intense ulceration which often leads to perforation of the cornea within 48 hours. In this research, we induced keratits in the rabbits by inoculating Pesudomonas aeruginosa(9027) and observed the effect on the keratitis and the irritation against the external eye. Also we mesured the minimum inhibitory consentration(MIC) of Coptidis Rhizoma, Fraxini Cortex, Jinpisan(秦皮散) by agar diliution method and the anti-bacterial activites by disk method. The tested bacteria were as follows : a) Pseudomonas aeruginosa (9027), b) Streptococcus pneumoniae(6303), c) Staphylococcus epidermidis(12228), d) Staphylococcus aureus(6538P). The results were as follows ; 1. The groups which were applied eye washes of Fraxini Cortex, Jinpisan reavealed a significant effect, but the group applied eye wash of Coptidis Rhizoma reveaded no effect on Pseudomonas aeruginosa keratitis. 2. Applying eye washes of Coptidis Rhizoma, Fraxini Cortex, Jinisan revealed an irritation against external eyes. 3. Coptidis Rhizoma showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylucoccus aureus by agar diliution method 4. Coptidis Rhizoma showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus by disk method. 5. Fraxini Cortex showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus by agar diliution method 6. Fraxini Cortex showed an anti-bacterial activity on Pseudomonas aeruginosa, Sireptococcus pneumoniae, Staphylococcus epidermidis, Staphy1ococcus aureus by disk method. 7. Jinpisan showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus by agar diliution method. 8. Jinpisan showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus by disk method. According to the above results, Fraxini Cortex, Jinpisan(秦皮散) are recognized to have an effective treatment on the Pesudomonas aeruginosa keratitis, so this experiment is thought to be a basic ingredient in proving the effect of Fraxini Cortex, Jinpisan which is applied many in documents and clinical medicine. In the comparison of anti-bacterial activity and results of treatment on the Pesudomonas aeruginosa keratitis, Jinpisan(秦皮散) was more effective than Coptidis Rhizoma, Fraxini Cortex.

  • King Gojong was the twenty-sixth King in the Choseon Dynasty. He took the throne when he was only 12 years old and had to set up regency for 10 years. During his period, situations were worsened in both domestic and foreign affairs. In the end, after 3 years from abdication of the throne, the Choseon Dynasty was overthrown in compliance with a coercion by Japanese empire. He died in 68 years old. We can assume that his inveterate disease are weakness of the spleen and the stomach. In addition, he suffered from a boil, a cold, dermatosis, eye disease, an external wound, dentistry disease, arthritis, etc. The official cause of his death was cerebral hemorrhage. But we assume that the possibility of poison murdering is high.

  • Purpose: This study was performed to investigate the relationship between ocular and allergy symptoms in children by environmental pollutants emitted from new constructed building. Methods: Two different types of survey (6-Item Dry Eye Questionnaire and Ocular Surface Disease Index) were used to study dry eye syndromes and ocular subjective symptoms for a six-grade of elementary school students (54 males and 61 females) in newly built buildings in the past three month, located near capital city, Seoul. Atopy and medical history of allergic rhinitis were investigated with using questionnaire for allergy, and also nose itchiness and ocular symptoms were checked as visual analog scale(10-score) with using questionnaire of allergy rhinitis and conjunctivitis under the guideline of ARIA(Allergic Rhinitis Impacts on Asthma). Results: Fifty seven students (50%) from DEQ and 19 students (16.52%) from OSDI were diagnosed as dry eye, and 18 students (15.79%) were diagnosed as dry eye from both questionnaires. It was surveyed that 45 students (39.5%) and 29 students (25.4%) had atopy and allergy rhinitis, respectively. Among 45 students having atopy, 30 students and 8 students were diagnosed as dry eye with using DEQ and OSDI, respectively. And also, 22 students were diagnosed as dry eye by DEQ and 5 students were diagnosed as dry eye by OSDI from 29 students having allergy rhinitis. Among 29 students having both medical history atopy and allergy rhinitis, 15 students detected observable ocular symptom. The complicating allergy symptoms with ocular syndrome were arranged with sneeze, nose itchiness, nose stuffiness, and runny nose in order of frequency. As students recognized eye symptoms, the number of allergy found and student's number were increased proportionally. Conclusions: It was found that children's subjective ocular symptoms were confirmed in the environment as newly built building. The number of student for dry eye was proportionally increased to students having atopy and allergy symptoms.

  • During New year's day and Thanksgiving holiday, the 1339 Information Center in Gwangju and Jeonnam received an emergency medical situation and carried out the analysis as follows ; 1. The reason for the higher phone guidance(72%) of the hospital was based on the simple query for the pain control rather than emergency care. This was explained by the unfamiliar environment of the holiday movers. Pharmaceutical guidance(12.6%) in rural area was also given during the holidays. 2. The disease counselling(2.4%) and emergency treatment instruction(First Aid)(1.6%) decreased because of the small number of request for the diseases. This explained the decrease of the disease counselling. 3. The phone calls increased 8-13 times more than usual. Five-day holidays could have more emergency patients than three-day holidays. During New year's day and Thanksgiving day, the number of received phone calls was 6,444(25.7%) and this accounted for one fourth of the total number in 2007. 4. The number of the patients increased on New year's day and Thanksgiving day because most of the medical institutions and pharmacy were off duty. 5. The patients were centered in Internal medicine and pediatrics. This showed the food-borne diseases and air-borne infection such as common cold. 6. During Thanksgiving day, ophthalmologic patients having viral keratoconjunctivitis(Apollo eye disease) increased 8 folds than in New year's day. It was estimated from the continuous epidemic of Apollo eye disease. 7. There broke out the traffic accidents, food poisoning, infectious diseases, dermatological diseases due to seasonal and environmental changes during the holiday move.

  • Purpose: The relativity of factors between low vision and socioeconomic status were investigated. This study represented the preliminary data for establishment of public eye health policy. Further, this report would encourage people to change the social attitudes about the eye health equity of the nation. Methods: The number of people (2,514 people) who have been tested the forced visual activity were examined as it was referred the Korea National Health and Nutrition Examination Survey (KNHNE) of 2009-year data. The prevalence rate of low vision of subjects which are related with house income, education level and occupations were conducted with ttest and chi square test. Besides, the Binominal Logistic Regression was conducted to measure the odds ratio of the subjects. Results: In outline, the prevalence rate of low vision was high with low house income, low education level and low function. The odds ratio represented that 2.77(95% CI, 1.72-4.47) at low house income group and 4.02(95% CI, 1.75-9.23) at the case of below primary school education level. Moreover, the results of unemployed group showed 3.65(1.14-11.68) from the odds ratio measurement. Conclusions: The eye health policy need be instituted which is broad and meticulous support to ease the eye health equity of low eye sight patients. For instance, the education about eye health, examination business of eye disease, and education of assistant units which are useful for low eye sight would suggest practical solution.

  • The efficacy of B$_1$l live vaccine which is used successfully in chicken was examined against Newcastle disease in quails. A total of 480 male quails were divided into 4 groups, of which 3 groups were vaccinated via drinking water, eye instillation and spraying method and the remaining was employed as a nonvaccinated control group. At 3 weeks after the first vaccination a part of quails in each group was revaccinated. Efficacy of the vaccine was evaluated by the antibody responses and the protection rates after challenge with a virulent NDV. Vaccination of quails with $B_1$ NDV at 10 days of age resulted in beneficial effect compared to nonvaccinated group regardness of vaccination methods adopted although general protection rates were considerably low. Twice vaccination gave higher protection than once vaccination. Hemagglutination inhibition antibody responeses were significantly higher in groups of quails vaccinated by spray and eye instillation method than by drinking water administration. Antibody responses were marked at 2 weeks onward and until 5 to 7 weeks after vaccination. Antibody responses were rapid and marked after second vaccination. However, antibody level did not last longer than 5 to 7 weeks postvaccination. Vaccine caused no adverse effect on quails in terms of growth'rate, body temperature or clinical signs.

  • The world faces difficulties in terms of eye care, including treatment, quality of prevention, vision rehabilitation services, and scarcity of trained eye care experts. However, it is difficult to develop a method for classifying various ocular diseases because the existing dataset for retinal image disclosure does not consist of various diseases found in clinical practice. We propose a method for classifying ocular diseases using the Retinal Fundus Multi-disease Image Dataset (RFMiD), a dataset published in the ISBI-2021 challenge. Our goal is to develop a robust and generalizable model for screening retinal images into normal and abnormal categories. The performance of the proposed model shows a value of 0.9782 for the test dataset as an area under the curve (AUC) score.
