Objective : We evaluated a modified trans-middle temporal gyrus (MTG) approach with good postoperative visual preservation for patients with trigonal tumors. Methods : Three patients with a trigonal tumor were treated via the modified trans-MTG approach guided by a neuro-navigator. Modified trans-MTG approach involve the incision at the MTG within 5 mm to the superior temporal sulcus. This approach makes a proper trajectory to the trigone but also reduces the retraction injury of MTG as little as possible to prevent postoperative visual field defect. Preoperative and postoperative visual field examination using perimetry was performed to evaluate the visual field. Results : Three patients underwent surgery for lymphoma in the right trigone, meningioma in the left trigone, and focal enhancing nodule in the right paratrigonal area, respectively. In case of lymphoma, preoperative examination showed a left homonymous hemianopsia : one week later after surgery, a visual field examination was performed and revealed improvement of the visual field defect. In case of the meningioma, the preoperative examination showed no visual field defect : one month later, the visual field had no defect. In case of the enhancing nodule, preoperative visual field testing revealed a partial left homonymous hemianopsia. Visual examination within one month after surgery showed no visual field defect. All three patients treated with the modified trans-MTG approach showed no visual deterioration after surgery. Conclusion : The modified trans-MTG approach provides a safe and useful technique for trigonal tumors without postoperative visual field deterioration and affords adequate exposure of the trigonal tumor with a short trajectory.

Bone destruction was induced experimentally by the insertion of a bit of the arsenic compound into the pulp chambers of the right premolars and the artificial bone defects were produced in the periapical regions of the left premolars in 7 dogs. The serial standardized periapical radiographs using aluminum stepwedge attached to the XCP instruments, and resin bite blocks were taken following insertion of arsenic compound and at 2, 4, 7, 10, 14, 17, 21, 24 and 28 days in case of bone destruction and following bone injury and weekly thereafter for a total of 14 weeks in case of bone formation. The errors of the method were determined with error estimators described by the Duinkerke. All radiographs were evaluated by the visual examination after joint evaluation by three dental radiologists and analysed with densitometer. The following results were obtained; 1. Analysis of the bone destruction process 1) The error of the method in estimating two distances proved to be small (S.D. for the measuring error; 0.04㎜, S.D. for the over-all error; 0.06㎜, S.D. for the positioning error; 0.05㎜) 2) The radiographic changes were observed after 7 days in 6 cases, 4 days in 1 case and 10 days in 1 case by the visual examination. 3) Aluminum equivalent values were diminished after 2 days and the diminution of 0.58±0.19㎜ was demanded to be detected by the visual examination. 2. Analysis of the bone formation process 1) The error of the method in estimating two distances proved to be small (S.D. for the measuring error; 0.03㎜, S.D. for the over-all error; 0.04㎜ S.D. for the positioning error; 0.04㎜) 2) The radiographic changes were observed after 2 weeks in 5 cases and 3 weeks in 2 cases by the visual examination. 3) Aluminum equivalent values were increased after 1 week and the increase of 0.45±0.15㎜ was demanded to be detected by the visual examination. 4) Aluminum equivalent values were increased continuously for 7 or 9 weeks but there as only extremely small change after 10 weeks.

To develop the Korean-Version-Improvement program for ordinary people, we investigate how Korean-High-Intelligent people use their cognitive function, intellectual capacity and Intelligent Quotient test. Using Mensa iq test, we classify intelligent examination tool into various components; visual, geometrical component and cognitive interpretation component. Also we organized each component, got database of intelligent subjects sample, classified itemized availability. Based on these things, we prove efficiency of intelligent examination tool. We found out that high intelligent people showed high Intelligent Index using visual cognitive stimulation with cognitive function when subjects were exposed to certain situation; solving the problem. This intelligent examination tool is low price and safe and easily carrying out with personal computer. If we develop intelligence quotient examination customized with mental retardation populations, a variety of subjects will improve their cognition with efficiency and inexpensively.

The thoracoscopic study was reported on 21 cases of spontaneous pneumothorax requiring surgical management, and clinical values of thoracoscopic examination on spontaneous pneumothorax were also discussed. patients were treated in the Department of .Thoracic Surgery, Hanyang University Hospital for the period of two Years from May 1972 to April 1974. For exact detection of etiologic factors on spontaneous pneumothorax, the thoracoscopic examination in the intrapleural space was performed in parallel with X-ray study. this study, the difference of diagnostic and therapeutic significance between radiological and thoracoscopic findings were observed and compared simultaneously. The results are summerized as follows: Patients age was distributed between 3 and 70 years old with highest incidence in the age group of sixty decade [33. 3%], and sex ratio of male to female was 5:2. The tuberculous processes which developed superficial subpleural layer in the lung parenchyme, on the pulmonary surface could be observed by thoracoscopic examination in a characteristic picture. detection ratio of pulmonary tuberculosis by the radiologic study to that by thoracoscopy was 8:2. The adhesion between the visceral and the parietal pleura which could possibly make a rupture of the alveola and the visceral pleura was found to be localized in a small area of the lung surface. The other part of the lung surface was free of the adhesion and, therefore, the movement of the lung took place completely without any difficulty. The ruptured orifice of the pleura and pathological changes surrounding the orifice can be detected by thoracoscopy, but not by other means such as radiologic examination. A single tuberculous bleb and multiple emphysematous blebs were found on 6 cases out of 21 cases of spontaneous pneumothorax. Among these cases, radiologic Study revealed the bleb only in one patient. On the other hand, the blebs were found in all the six patients by means of thoracoscopic examination. It gives the detection ratio of bleb by radiologic study to that by thoracoscopy was 1:6. By thoracoscopy, the rupture on the lung surface were visualized on the 10 patients out of a total of 21 patients [10 patients of visual rupture]. However, the rupture of the pleura was not observed on the rest of 11 patients even by thoracoscopic examination [11 patients of non visual rupture]. Five patients [50%] out of ten who had the visual rupture on the lung surface was required a surgical operation to remove pneumothorax. For the patients who were detected to have the visual rupture of the pleura by thoracoscopy, be considered in the early stage of closed thoracostomy. of 21 patients, 16 patients [11 patients of non visual rupture of the pleura and 5 patients of visual rupture of the pleura] who received no surgical management, were treated with closed thoracostomy with continuous suction, and the` pneumothorax was healed completely up in each cases. Therapeutic measures for the remaining 5 patients of visual rupture of the pleura who were subjected to surgical approach for radical treatment of spontaneous pneumothorax were accordingly complicated, and the following different procedures were properly indicated case by case, that is, rib resection thoracostomy, simple closure of ruptured visceral pleura, wedged resection of the lung, and lobectomy.

Providing visual information about the fetus to the mother by the ultrasound examination was found to be an effective nursing intervention to promote Maternal-Fetal Attachment. In keeping with the purpose of the study, to evaluate the effect of providing visual information by ultrasound on level of Maternal-Fetal Attachment, a non-equivalent experimental group quasi-experimental design was used. The data were collected using Cranley's Maternal-Fetal Attachment Scale(1981) with a research questionnaire that consisted of 16 items on general characteristics and 23 items on Maternal-Fetal Attachment from November 2, 2000 to August 11, 2001. Subjects were 126 pregnant women who were received visual information by ultrasound and 123 pregnant women who did not receive visual information by ultrasound after finishing examination. The data were analyzed by using the SPSS/PC+ window 10.0 version program. The results of this study were as follows: There was no statistical difference in general characteristics between both groups. The scores on Maternal-Fetal Attachment at second trimester show no statistical difference (t=1.123, p=0.263). The scores on Maternal-Fetal Attachment in both groups increased between the second trimester and third trimester. However, the increase was greater in the group receiving visual information by ultrasound as compared to the group which did not receive the visual information(t=-2.152, p=0.032). This result shows that providing visual information about the fetus by the ultrasound examination is effective in increasing Maternal-Fetal Attachment.
