We suggest how to search news data by dividing structurely, by classifying meaningly, and by itemizing them by contents. The structural division divides the scene using correlative information between frames such as the distribution of the space brightness and the irregularity of brightness, and time relation etc. The meaning classification means to classify the detailed contents of news video as articles comparing special information extracted frame key frame with previous knowledge information. This study classifies the articles as the anchor's scene and the non-anchor's scene using the character that the progress of news is repeated centering around the anchor frames by periods. We get the non-anchor's scene to search the news data itemizing speech scene, interview scene and general scene, and classifying as articles. Also, we use the function of searching for summary by news icons and search the caption by processing the integration of caption, and design them to be able to search the news video quickly classifying news video as contents and indexing them.

Recently, retinal blood flow has been studied with several methods, targeted dye delivery method, fluorescent vesicle system, laser Doppler velocimetry, acridine orange staining method. Authors presented a new method, fluorescein leukocyte angiography using a scanning laser ophthalmoscope which include external staining of leukocyte with fluorescein dye and reintroduce the fluorescent leukocyte into the blood flow. Authors tried to check security of external fluorescein staining of leukocytes and separation of fluorescent lymphocytes from whole blood and supernatant fluid using Ficoll-Paque, with cell viability, leukocyte recovery rate and erythrocyte contamination rate. There was no significant difference in cell viability, leukocyte recovery rate and erythrocyte contamination rate between fluorescein staining group and non-staining group. Fluorescent lymphocytes could be separated from whole blood and supernatant solution after gravity sedimentation with 6% hetastarch and the gravity sedimented group had low erythrocyte contamination rate than whole blood group(p≤0.05). In conclusion, external fluorescein staining procedure of leukocyte during fluorescein leukocyte angiography could be performed without cell injury compared to non-fluorescein staining group and fluorescent lymphocyte could be separated from whole blood and supernatant fluid after gravity sedimentation.

This prospective clinical study was conducted to observe the outcome of surgical skin wound closure in the lower eyelid using absorbable suture material in young children. We operated 30 eyes of 15 patients for entropion and epiblepharon using 6-0 chromic catgut. The patients were carefully examed 1 day, 7 days, 10 days, and 3 months postoperatively for inflammation, wound infection and grossly visible scar. During the follow-up, 6-0 chromic catgut was absorbed and spontaneously disappeared between 7 days and 10 days. There were no inflammation and wound infection in all cases. But the partial visible scar by wound dehiscences was noted in one case. Considering these finding, we think that skin closure with chromic catgut has the advantages of the avoidance of patient discomfort, suture removal, and time spared for the surgeon. Especially, this is extremely helpful in young children.

Background: Sensory heterotropia is defined as a secondary deviation following loss or severe reduction in visual function in one eye. Surgical results in sensory heterotropia are quite unpredictable. Overcorrections or undercorrections occur frequently, and surgical alignment is rarely stable. Methods: The authors designed a study based on medical records of 28 patients with sensory heterotropia. The study included the etiology of visual impairment, type of strabismus as the age of the onset of visual loss and surgical outcome. Results: The range of age was from 5 to 50 years old(mean age, 20.6 years) and onset of visual impairment was from at birth to 25 years old(mean age, 7.6 years). The etiologies were anisometropia (8 cases), corneal opacity (7 cases), optic nerve disease (6 cases), retinal disease (5 cases) and congenital cataract (2 cases). The direction of deviation in patients under 5 years of age were esotropia in 7 cases and exotropia in 4 cases. In patients over 5 years of age esotropia accounted for 1 case and exotropia for 16 cases. Immediately after surgery 20 cases were successful, 3 cases undercorrected and 5 cases overcorrected. On follow-up, 4 cases out of 20 presented recurrence, one case of consecutive exotropia in a esotropic patient and straight alignment in one overcorrected patient. Also recurrence was low in the eyes with limitation of motion after operation suggesting that limitation of motion may be a inhibiting factor of recurrence in patients with sensory heterotropia. Conclusion: Although our average follow-up is only 23 months, We feel that surgical results in patients with sensory heterotropia appear to be stable enough to allow the patients of good cosmesis.

Objectives : To establish an effective collaborate medicine treatment of acupuncture and western medicine for treating frozen shoulder patients. Methods : 59 voluntary patients were randomly assigned to Eastern treatment group(E group, n=22), Western treatment group(W group, n=17) and East-West treatment group(EW group, n=20). The E group received acupuncture treatment on LI15, TE14, GB21 and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The W group received suprascapular nerve block, subacromial injection and trigger point injection, twice a week for 4 weeks. The EW group received acupuncture and injection treatment including nerve block. All groups were instructed to practice self exercise during their daily lives. Evaluations were made before treatment and after treatment based on the change in shoulder Range of Motion(ROM) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). The obtained data were analyzed and compared. Results : The patient's satisfaction scores were E group 5.67, W group 7.73 and EW group 7.67. The E group and the EW group showed significant improvement in abbduction, adduction and flexion(p<0.05). The W group showed significant improvement in adduction(p<0.05). Abduction significantly improved(p<0.05) in the EW group compared to E group and W group. Flexion also showed improvement in the EW group, but the difference among the 3 groups was statistically insignificant. The three group's difference of change in extension and adduction was insignificant(p>0.05). Conclusion : Acupuncture and nerve block alone significantly improved ROM in frozen shoulder patients. Also collaborate treatment of acupuncture and nerve block significantly improved ROM in frozen shoulder patients. But the difference of the three treatments were significant only for improving abduction(p<0.05).

Background: The study on retinal blood flow has been continuously pursued and recently new methods such as targeted dye delivery, fluorescent vesicle system, laser Doppler velocimetry and acridine orange staining method has been presented. The authors developed a new method, fluorescein leukocyte angiography using a scanning laser ophthalmoscope which include external staining of leukocyte with fluorescein dye and reintroducing this fluorescent leukocyte into the blood flow. However, visualization of the leukocytes was limited since the leukocytes used were from the peripheral blood in a small animal. Methods: The authors removed leukocytes from the spleen and stained these leukocytes which were reintroduced into the blood flow to observe the retinal and choroidal blood circulation. In four pair of rats, one group was injected with the leukocytes of another rat's spleen and the other group were injected with the leukocytes of each own's individual spleen and all underwent angiography. Results: There were only few lymphocytes visualized in the group of rats which eceived allo-injection of leukocytes and in the other group the lymphocytes were numerous and also had a longer existence. Conclusions: In small animals like rats the visualization of the lymphocytes used from the spleen was better than the those from the peripheral blood and lymphocytes from one own's spleen was useful for longer periods of visualization.
