The purpose of this study is to develop the curriculum of power transmission and distribution fields in department of electricity by job analysis approach in order to bring up technicians with the adaptive power of industrial field in a rapidly changing industrial society. The method of this study was to carry out the research of questionnaire for teachers of department of electricity in order to analyze the demands of school education. The various actual data from this study were analyzed to make a basic plan, and then job approach was executed by the verification method through the interview and observation with engineers of Korea Electric Power Co. in Cheonnam province, and finally task training data which could be reflected to curriculum were extracted.The main results of this study were as follows: (1) Using the verification method about the power transmission and distribution field, job approach was executed, and task training data were extracted. (2) Analyzing quantitatively importance, frequency, and difficulty about thirteen tasks, the tasks able to reflect curriculum of the department of electricity were selected. (3) Trying to find out the problems of current curriculum, and suggested new curriculum to include the required ability for the students in future industrial society based on the questionnaire and field interview.

Purpose: To report a case of central serous chorioretinopathy development after glaucoma filtering surgery and spontaneous resolution in a patient with a history of central serous chorioretinopathy in the contralateral eye. Case summary: A 46-year-old male with a history of chronic uveitis in both eyes presented with uncontrolled intraocular pressure (IOP) in his left eye. Initial IOP was 34 mm Hg in his left eye. On preoperative evaluation, central serous chorioretinopathy, which was diagnosed in another clinic 1 month prior, was observed in his right eye. Slightly pale optic disc and retinal nerve fiber layer defects were noted in the left eye. However, macular abnormalities were not observed in the left eye. Trabeculectomy and peripheral iridectomy using mitomycin C were performed in the left eye. The patient was prescribed triamcinolone 8 mg daily for 4 days to reduce the post-surgical inflammation. On postoperative day 4, IOP in the left eye was 7 mm Hg and newly developed central serous chorioretinopathy was noted. On follow-up, IOP was maintained at 7-10 mm Hg and central serous chorioretinopathy disappeared 7 months postoperatively. Conclusions: When clinicians consider performing an ophthalmological procedure in a patient with a history of central serous chorioretinopathy in the contralateral eye, careful observation of central serous chorioretinopathy development is recommended.J Korean Ophthalmol Soc 2014;55(12):1895-1900

Purpose: Malignant glaucoma is a rare complication of anterior segment surgery. The authors present a case of a malignant glaucoma-like phenomenon during cataract surgery in a primary open-angle glaucoma (POAG) patient. Case summary: A 74-year-old man with POAG underwent a cataract surgery in his left eye. After phacoemulsificiation, sodium hyaluronate was used to form the capsular bag for intraocular lens implantation. Following this procedure, the capsular bag space and anterior chamber became shallow. Intraocular pressure (IOP) elevated, and the shallowing of the anterior chamber and capsular bag space continued to a dangerous level. The surgical procedure was stopped and postponed for two days. After two days, IOL was successfully implanted in the posterior bag. Conclusions: Although the preoperative ophthalmologic examination failed to reveal a zonular problem, there was a possibility for a small area of zonular defect. A malignant glaucoma-like phenomenon was suspected to have occurred due to leakage of sodium hyaluronate or balanced salt solution into the vitreous through a small area of zonular dialysis. If a similar condition, occurs delayed surgery for IOL implantation would be more effective than vitrectomy or laser treatment. J Korean Ophthalmol Soc 2010;51(8):1150-1154

This study was designed to elucidate the anti-inflammatory, cardiovascular, anti-thrombotic, and analgesic effect of Whalrakdan. The anti-inflammatory effects was measured by the method of carrageenin induced edema, protein leakage test using CMC-pouch, and the effect of Whalrakdan on the cardiovascular system was observed by the change of flow rate of Ringer solution in the vascular system in the ear of rabbit. and the contraction and dilatation of rat tail artery. Death rate, platelet aggregation, plasma coagulation activity, antithrombin activity was observed for the measurement of the anti-thrombotic effect of Whalrakdan, and the analgesic effect was measured by the acetic acid method and hot plate method. The result was as follows: 1. After 2 or 3hour of Whalrakdan administration, carrageenin induced edema and CMC-pouch protein leakage was significantly decreased. 2. The slight anagesic effect of Whalrakdan extract was confirmed by the observation of writhing syndrome, paw licking time, and escape time. 3. The droplet of Ringer solution increased according to the increase of concentration of Whalrakdan extract, and the vasoconstriction decreased dependantly to the concentration of Whalrakdan extract. 4. The anti-thrombotic effect of Whalrakdan was observed by the decrease of death rate, the inhibition of platelet aggregation, and the increase of anti-thrombin activity.

Purpose: To determine the effect of cataract extraction on visual field damage in glaucoma patients with cataracts. Methods: Sixty-two eyes of fifty glaucoma patients (primary open-angle glaucoma, angle-closure glaucoma, and normal-tension glaucoma) were divided into three groups according to the MD (mean deviation) value from the Humphrey automatic visual field test. The PSD (pattern standard deviation) values were analyzed before and after the cataract surgery. Additionally, the visual acuity, intraocular pressure and the number of antiglaucomatous agents were compared. Results: All of the three groups, showed significant improvement in visual acuity. However, there was only a significant decrease in intraocular pressure at three months postoperatively. When comparing the mean MD values of each group, there was a statistically significant difference between the mild defect group and the severe defect group, but no statistically significant difference in the moderate defect group. There was also no statistically significant difference in PSD values in the any of the groups before and after cataract surgeries. Conclusions: In glaucoma patients with cataracts, there were no significant differences in PSD values before and after cataract surgery. Additionally, to perform an adequate cataract operation in advanced glaucoma patients without the progression of visual field damage, lowering intraocular pressure and improving visual acuity is helpful.
