Purpose: To evaluate the clinical manifestations of various glomerular diseases in children, a clinicopathological study was performed in 52 children who had renal biopsy. The type and relative incidence of the glomerular pathologies were analyzed, and the clinical predictability and usefulness of renal biopsy in glomerular diseases were assessed. Methods: Medical records of fifty two children with renal disease who had undergone percutaneous renal biopsy under ultrasonic guidance at Chungnam University Hospital from October 1995 to August 2003 were reviewed. In addition, we compared the clinical findings before renal biopsy with the pathological diagnosis. Results: The male to female ratio was 1.6:1 and they were $9.8\pm2.6$ years old on average. The chief complaints for biopsy were hematuria in 22 cases which was the most common (42.3%), proteinuria in 16 cases(30.8%), and hematuria & proteinuria(26.9%). Among the 22 cases of hematuria, there were 15 cases of gross hematuria(68.2%) and 7 cases of microscopic hematuria(31.8%). In terms of histopathologic diagnosis, most of them were primary glomerular diseases(84.6%), which included IgA nephropathy(28.8%), thin glomerular basement membrane disease(25.0%), focal segmental glomerulosclerosis(FSGS)(11.5%), membranous proliferative glomerulonephritis(7.7%), minimal change lesion(3.8%), acute poststreptococcal glomerulonephritis(3.8%) and membranous glomerulonephritis(3.8%). The clinical manifestations and pathologic diagnosis were not correlated. Conclusion: The clinical manifestations could not predict the pathological diagnosis. Therefore, renal biopsy would be inevitable in diagnosis of glomerular diseases for effective management and assessment of prognosis.

Purpose: The aim of this study was to evaluate the effect of increased vertical dimension of occlusion on lower facial changes by facial type. Materials and methods: Lateral cephalograms from 261 patients were obtained and classified by sagittal (Class I, II, and III) and vertical (hypodivergent, normodivergent, and hyperdivergent) facial patterns. Retrusive displacement of soft tissue Pogonion and downward displacement of soft tissue Menton were measured in each group after 2 mm of vertical dimension of occlusion was increased at the lower central incisor using a virtual simulation program. The ratio of both displacements was calculated in all groups. The statistical analysis was done by 2-way ANOVA and Post hoc was done by Tukey test (5% level of significance). Results: Retrusive displacement of soft tissue Pogonion in Class III group was statistically different compared to Class I and II, and in vertical facial groups all 3 groups were significantly different (P<.05). Downward displacement of soft tissue Menton showed statistically significant difference between all sagittal groups and vertical groups (P<.05). The ratio of both displacements showed statistically significant difference in all sagittal groups and vertical groups (P<.05), and Class II hyperdivergent group had the highest value. Conclusion: Lower facial change was statically significant according to the facial type when vertical dimension of occlusion increased. Class II hyperdivergent facial type showed the highest ratio after increase in vertical dimension of occlusion.

Original scripts of e-learning lectures for the CEOs of corporation S were analyzed using topic analysis, which is a text mining method. Twenty-two topics were extracted based on the keywords chosen from five-year records that ranged from 2011 to 2015. Research analysis was then conducted on various issues. Promising topics were selected through evaluation and element analysis of the members of each topic. In management and economics, members demonstrated high satisfaction and interest toward topics in marketing strategy, human resource management, and communication. Philosophy, history of war, and history demonstrated high interest and satisfaction in the field of humanities, whereas mind health showed high interest and satisfaction in the field of in lifestyle. Studies were also conducted to identify topics on the proportion of content, but these studies failed to increase member satisfaction. In the field of IT, educational content responds sensitively to change of the times, but it may not increase the interest and satisfaction of members. The present study found that content production for CEOs should draw out deep implications for value innovation through technology application instead of simply ending the technical aspect of information delivery. Previous studies classified contents superficially based on the name of content program when analyzing the status of content operation. However, text mining can derive deep content and subject classification based on the contents of unstructured data script. This approach can examine current shortages and necessary fields if the service contents of the themes are displayed by year. This study was based on data obtained from influential e-learning companies in Korea. Obtaining practical results was difficult because data were not acquired from portal sites or social networking service. The content of e-learning trends of CEOs were analyzed. Data analysis was also conducted on the intellectual interests of CEOs in each field.

It is important for regional comparative analysis about employment-population rate of young man and total employment-population rate to a policy data of central and local government. Through the result of comparative analysis, Central and local government can use policies distinctively according to the region and keep the efficiency of detail policy application. This study shows that we classify Seoul Metropolitan region and Gangwon, Choongcheong, Honam, Youngnam region from 16 cities and provinces, and calculate total employment-population rate and employment-population rate of young man for these regions, and then compute the relative ratio between these employment-population rates, and finally compare the relative ratio by these regions. According to main results of this article, total employment-population rates in all the regions have not changed, whereas employment-population rates of young man have been decreased in all the regions but the rates in Seoul Metropolitan region and Choongcheong region have been increased for recent years. Moreover the changes by period of the relative ratio have been almost same as that of young man's employment-population rate.

Purpose : The main Purpose of this study is to develop new payment rates for services of Radiation Oncology, considering costs of treating patients. Material and Methods : A survey of forty hospitals has been conducted in order to analyze the costs of treating patients. Before conducting the survey, we evaluated and reclassified the individual service items currently using as Payments units on the fee-for-service reimbursement system. This study embodies the analysis of replies received from the twenty four hospitals. The survey contains informations about the hospitals' costs of 1995 for the reclassified service items on Radiation Oncology. After we adjust the hospital costs by the operating rate of medical equipment, we compare the adjusted costs with the current Payment rates of individual services. Results : The current payment rates were 5.05-6.58 times lower than the adjusted costs in treatment planning services, 2.22 times lower in block making service, 1.57-2.86 times lower in external beam irradiation services, 3.82-5.01 times lower in intracavitary and interstitial irradiation and 1.12-2.55 times lower in total body irradiation. Conclusion : We could conclude that the current payment system on Radiation Oncology does not only reflect the costs of treating patients appropriately but also classify the service items correctly. For an example, when the appropriate costs and classification are applied to TBI, the payment rates of TBI should be increased five times more than current level.
