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.

To investigate a horizontal windrose and the mixing height in Masan coastal area, a local atmospheric flow and the concentration of air pollutants were analyzed by abserved data from AWS, airsonde and air sampler. The land-sea breeze model and the ISCST2 model of U. S. EPA(Environmental Protection Agency) were used to predict the concentration of air pollutants such as SO2 and TSP. As a result, during spring the principal wind direction in the Masan region is mainly represented by windrose of the WNW and NW, which can be induced by land breeze and the SE and SSW of sea breeze even if weak wind speed. The mixing height during the measurement was marked with the range from 400 m(0900 LST) to 1450 m(1500 LST), and the height of an inverse layer was presented as the range from 30 m(2100 LST) to 150 m(0300 LST). It is very important to cosider the local wind field for the accurate diffusion and movement of air pollutants in coastal urban area. The atmospheric flow was simulated by the two-dimensional local wind model upon considering the orographic characteristics such as land-sea contrast, mountain valley and urban building. The result of air quality simulated by ISCST2 support that the dispersion pattern of the pollutants in that area was followed as local circulation system in coastal urban area.

We fabricate n-doped diamond thin films by hot filament chemical vapor deposition method(HFCVD) using ammonia as a doping gas and investigate the effect of the substrate temperature and the ammonia gas ratio upon the diamond film morphology. The SEM, Raman spectroscopy, and the XRD analysis are executed to characterize film morphology. Field emission property of the film is measured also. We find optimum conditions of the substrate temperature and the ammonia gas ratio to deposit high quality n-doped diamond thin films.

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.

This thesis was written in order to help set groundwork of the mutuality between brain hormon and Shin-myung(神明) activity. 1.Shin-myung(神明) means all spiritual functions, and Shin(神) represents thinking, myung(明) represents consciounsness. 2.As a origin of Shin-myung(神明) activity, in ancient times Heart(心) was regared as one, but since Chung-Dynasty(淸朝), Brain(腦) is regared as a main controller to manage Shin(神) in human body. 3.Shin-myung(神明) activity would should between Brain(腦) and Shin-Sin(心神) 4.Hormon is chemical substance to serve convey informations and stimuiate them. In Present day Western medical science, make an attempt to understand Shin-myung(神明) activity of Brain(腦) as a activity of hormon doings. In conclusion, Shin-myung(神明) represent that Brain(腦) include Mind-Sprit(情神) activity, and it can be able by the function of brain hormon activety.
