연석주 東新大學校 1998 論文集 Vol.10 No.-

LAS-base glass ceramics were prepared by mixing with base glasses(the ratio of Li_2O : Al_2O_3 : SiO_2 = 4.5 : 25 : 70.5wt%) and TiO_2 and ZrO_2 as the nucleating agent. With increasing nucleating agents, the crystallization temperature from glass to crystalline phase decreased. The principal crystalline phase after a heat-treatment was β-quartz solid solution. β-spodumene phase increased with heat-treatment temperature. High transparent glass ceramics was prepared by the addition of 5wt% ZrO_2 and the heat treatment at 850℃.

조주원,이정재,손유리,유영천,유석근 大韓成形外科學會 1999 Archives of Plastic Surgery Vol.26 No.3

A possible therapeutic effect of acetyl-L carnitine (ALCAR) on peripheral nerve injuries and the expression of Jun, the protein products of immediate-early genes(IEGs), in the spinal cord were investigated after sciatic nerve injury in Sprague-Dawley rats. Experimental animals were divided into 3 groups: intact sciatic nerve as a control group, surgical repair alone, and surgical repair with ALCAR treatment. Toe-spreading response, pinprick response, and compound action potential were measured to evaluate the recovery of sciatic nerve injury. Recovery of behavioral function and electrophysiological function both improved in the surgical repair with ALCAR treatment group. Weak basal expression of Jun was shown in the ventral horn the of spinal cord in the control group. In the surgical repair alone group or the surgical repair with ALCAR treatment group, Jun expression persisted until 28 days after injury in the ventral horn of the spinal cord. Moreover, the surgical repair with ALCAR treatment group showed more increased expression of Jun than the surgical repair alone group. These results suggest that ALCAR facilitates the functional recovery after peripheral nerve injury.

제조환경변화와 기술회계의 중요성

洪孝錫,裵周漢 진주산업대학교 1997 論文集 Vol.36 No.-

The change of cost structures has challenged the accounting professions to develop a new cost management technique. Automation has changed the cost structure of many companies, so more costs are fixed in the short run. This change in cost mix has come to deemphasize such typical management accounting tools as cost-volume-profit analysis and break-even analysis. Given a high level of automation, most production cost is determined in the product planning and designing stages. So reducing the cost of products dramatically in the production stage is difficult, if not impossible. Most of the life cycle cost of products is determined in the designing stage. Shortening of the product life cycle has increased the importance of delivering a competitive product to the market quickly. Any errors in product cost or product quality are difficult to correct quickly because product life cycles are so short. The purpose of this study is to investigate the magnitude of technology accounting in changing manufacturing environment. Technology accounting embodies the concept that technology costs, which include plant, equipment, and information systems, should be treated as direct costs, equivalent to direct labor and material. Most technology costs nowadays are accounted for by amortization(or depreciation) and are included in indirect overhead. The problem with this method of accounting is that conventional amortization method is based on time, not production. In today's highly automated factories, traditional depreciation methods distort the product cost. There are two reasons for this problem. First, companies are basing their selection of depreciation methods and allocation bases on such criteria that do not mirror the manufacturing process. Second, the total of technology-related costs is large. The larger percentage technology costs take of total costs, the greater impact a misallocation puts on product cost. The goal of a technology accounting system is to more accurately assign capital investment costs to those products that benefit from them. This violates an important objective of cost accounting, which is to accurately match production costs to those products that benefit from them. Technologies are acquired to support specific activities, such as production requirements, engineering, or support tasks. Therefore, the cost of the asset should be charged only to those products that use it. By lumping technology costs are distributed over all activities masking the "real" cost of the activity.

Background: Diaphragmatic rupture may occur from blunt or penetrating thoracoabdominal trauma, which may be undiagnosed initially in the acute trauma, work-up and may remain unrecognized. Delayed traumatic diaphragmatic rupture is reported with increasing frequency and is associated with high morbidity and mortality. The purpose of this study was to present our experience and found out early diagnostic method, clinical presentation and management. Matehals and Methods: From March 1998 to February 2004, the 6 patients of delayed diaphragmatic rupture in our hospital were operated. We reviewed the diagnostic interval, symptom, diagnostic method, operative method and complication. Resutt: They were 3 men and 3 women. Mean age was 56.8:t15.8 years(range 29-69). Most common symptom was dyspnea. Delayed diaphragmatic rupture was right-sided in 4 patients, left-sided in 2. The average operative interval of delayed diaphragmatic rupture was 18.8 months(range 5-48). The diagnosis was chest x-ray and thoracic CT. Operative approach were only thorax in 4 patients and both thorax and abdomen in 2. Postoperative complication were observed in 4 patients, and the overall mortality was none. Conclusion: The delayed case of traumatic diaphragmatic rupture tends to be overlooked without suspicion, In all patients with thoracoabdominal blunt injury a rupture of the diaphragm must be suspected. With a high suspicion, a thorough physical examination and diagnostic method is recommended in order to avoid early or late complications.

송경욱,이석주,유창균,조용준 朝鮮大學校 建設技術硏究所 1999 建設技術硏究 Vol.19 No.3

The city is the social space with a lot of people having the various and different background and positions. That the city is the social space of high density means it is the space for convenient and comfortable life with the sense of community in frequent activities by overcrowded people and for this, intentional human behaviors within the city. From such a viewpoint, this research is to examine and analyze the publicity of external space of buildings with open space which is the important factor in improving the quality of city and the results of the research are as follows. It is found that the installation of open space has been made at the place where urban development is actively performed from the center of city with many users, but the open space which secures the comfort of the city and then attracts the people is not secured and is in the stage of legal restriction and the conversion of building owner's consciousness is needed. It is analyzed that most of open space are located at the front, but in fact there is no device which intercepts the eyes of pedestrian and open space users and since each space is divided by merely ground border, it is difficult to find the hierarchy or territory of two spaces and more considerations should be given for users. It is shown that the obligatory installations of open space such as bench are not equipped. Since the open space in urban area should be prepared in the side of publicity for users as well as for the urban comport, it is considered that the conversion of building owner's consciousness and institutional supports like incentive system should be followed. Moreover, open space have an influence on the diversification of architectural design, architects must consider the diversification of location, form and components of open space to make it an attractive space for users.
