Since its construction in the late 14th century, Hanyangdoseong had been carried out three major repairs and reconstructions during the 500 years of the Joseon Dynasty. In addition to the large-scale construction, small-scale construction continued until King Gojong era. In particular, in the 18th century, systematic construction management was implemented by the craftsmen and the military participated in the renovation of Hanyangdoseong in earnest, and the construction methods also developed rapidly. In the early 18th century, new construction techniques were attempted in various sections of the reconstruction work, and gradually became a common technology for repairing Hanyangdoseong in the late 18th century. The purpose of this study is to examine the characteristics and period of changes in the 18th century's construction technique, when the rapid development of Hanyangdoseong took place. To this end, the excavation results related to Hanyangdoseong, the remaining city wall, and the inscribed stones were used to identify and demonstrate the characteristics and change of the construction method.

Hepatitis-B virus is a serious problem in Korea, and about 7 to 8 % of the populations are in carrier state. The only drugs currently approved for hepatitis-B infection is a -inteferon. However, the cure rate with this treatment is low. Some patients are unresponsive to the interferon, and some relapse when is stopped. Recently, Lamibudine, a novel cytosine analogue, exhibits potent anti-viral activity against hepatitis B virus. The effect of lamibudine treatment is good for almost all patient, but some patients showing refractorlness and the mutant HBV appearance. We studied for what kinds of tests are available for predict the response of lamibudine. HBeAg positive cases are 11.5 % in the HBV -PCR postive group and 0.0% in the HBV-PCR negative group. HBeAg neagtive cases are 88.5% in the HBV-PCR postive group and 100.0% in the HBV-PCR negative group. These results indicate that HBV-PCR test are more reliable for predict the viral state of HBV infection. So the 띠ral status evaluation(infectivity) for HBV infection by HBeAg assay is not recommended. Further studies recruiting on patient’s clinical courses and liver biopsy studies may helpful to determine the HBV viral status.

지하공간의 활용이 활성화됨에 따라 지중구조물의 설치를 위해 깊은 굴착이 이루어지고 있으며, 굴착지반의 변형을 최소화하기 위해 흙막이벽체가 많이 활용되고 있다. 특히 도심지에서의 깊은 굴착이 진행함에 따라 벽체에 인접한 구조물의 피해가 발생하지 않도록 벽체 변형을 최소화하기 위한 방법들이 강구되어 왔으며, 이들 방법 중 하나가 버팀 선행하중 공법이다. 이 공법은 벽체의 버팀에 주동적으로 하중을 가해 벽체 변형을 억제하는 방법으로, 최근까지 이 공법에 관한 연구가 진행되어 왔다. 그러나 관련된 연구가 활발히 진행되었음에도 불구하고, 현재까지 선행하중에 대한 명확한 관리기준이 마련되어 있지 않다. 또한 굴착 깊이가 깊거나 배면지반의 상태에 따라 버팀의 작용력이 증가할 수 있으므로, 버팀에 가할 수 있는 선행하중의 크기가 감소할 수 있다. 그럼에도 불구하고 기존 연구결과에서 제안하고 있는 선행하중의 크기(작용하중의 50%이상)를 버팀에 일률적으로 적용하고 있다. 본 연구에서는 벽체의 배면지반조건에 따른 H-빔 버팀보의 선행하중 적용범위를 평가하고자 3차원 유한요소해석을 수행하였다. 해석결과, 연약한 지반조건이고 깊은 심도 굴착이 진행하는 경우 토압과 선행하중에 의한 버팀구조의 안정성에 문제가 발생할 가능성이 매우 큰 것으로 나타났다. 그리고 선행하중의 적용범위는 버팀 작용하중의 5%∼70%인 것으로 나타났다. As the utilization of the underground space is activated, deep excavation of ground has been conducted for the installation of underground structures, the earth retaining wall has widely used to minimize deformation of the excavated ground. In particular, as deep excavation is actively progressing in an urban area where structures are concentrated, methods to minimize the deformation of wall have been devised to prevent damage to the structure adjacent to the wall, and one of these methods is the pre-loading method. This method is a method of suppressing the deformation of wall by actively applying a load on the strut to be installed in wall, and research on this method has been conducted recently. However, although related studies have been actively conducted, the management standard for the pre-loading of bracing has not been clearly presented until now. In addition, since the working force in the strut may increase depending on the depth of excavation or the soil condition of the backfill, the magnitude of the pre-loading that can be applied to the brace may decrease. Nevertheless, the magnitude of the pre-loading (more than 50% of the working load) proposed by the previous research results has been uniformly applied to the strut. In this study, 3D finite element analysis was performed to evaluate the application range of the pre-loading of H-beam strut according to the soil conditions of backfill. As a result of the analysis, it was found that there is a very high possibility that a problem may occur in the stability of the structure of strut due to the earth pressure and the pre-loading when the soil condition is weak and deep excavation proceeds. And it was found that the application range of the pre-loading was 5%∼70% of the working load in strut.

In this study, the two sampling methods for blood glucose measurement were evaluated in order to reduce pre-analytical error. For this purpose, glucose levels of Li-heparinized plasma (LHP) and Na-fluorinated plasma (NFP) in blood collected from healthy volunteers were determined by using routine hexokinase procedures. The percentage range of pre-analytical error was quantitated by comparing LHP glucose values with NFP glucose values according to delaying analytical time (0, 60, and 120 min). LHP glucose values were decreased by 6.6% in 60 min., 17.7% in 120 min, whereas NFP glucose values decreased by 1.1% in 60 min, 2.0% in 120 min. Therefore it may be recommended that the NFP sampling method should be used for routine blood glucose determination in diabetes mellitus diagnosis.

Background/Aims: Currently, the role of liver transplantation in the treatment of hepatocellular carcinoma (HCC) with cirrhosis is controversial. What remain to be determined are the best treatment protocol and who are likely to have a good outcome after liver transplantation. Methods: Twenty-five patients with hepatocellular carcinoma underwent liver transplantation between 1993 and 2001 at the Department of Surgery, Catholic University of Korea. The follow-up period was from one month to 51 months. The pathologic findings, the recurrence, and survival of the 25 cases were analyzed. Results: Two patients had a tumor larger than 5 cm in diameter and three patient had above 3 nodules in number. Five patients had bilobar tumors. Vascular invasion was present in 11 patients (45.8%). Among the 25 patients, postsurgical TNM staging was stage III in 3 patients, stage IVA in 5 patients, and stage IVB in 1 patient. Number of high risk patients were 16 (64%). During follow-up, 23 of the 25 patients (92%) were alive and the number of disease-free survivals was 21 among the 23 patients (91.3%). Conclusions: According to our small experience, HCC can be a good indication of liver transplantation, especially in low risk patients and even in the recurrent cases. A long-term survival can be achieved by aggressive treatment. However, the best protocol remains to be determined, especially for the case with large tumors. (Korean J Gastroenterol 2003;42:42-49)

농작물들의 크기와 형태는 매우 다양하며 생육 환경도 각기 다르다. 따라서 드론을 활용하여 농약을 살포할 때에는 각 농작물에 대한 재배 환경과 특성이 고려되어야 하며, 이에 따라 드론의 비행고도, 전진속도 등 비행 조건이 달라져야 한다. 실제로 비행 조건에 따라 농약의 액적 유동이 크게 영향을 받게 되며, 살포 영역에 큰 변화가 발생하고 이로 인해 불균일한 액적 분포가 후류에 형성되어 농약의 전달 효율성이 떨어질 수 있을 뿐만 아니라 비산에 대한 위험성이 존재하게 된다. 본 논문에서는 농업용 드론을 사용하여 특성이 다른 3가지 농작물을 선정하고 드론의 비행 조건을 각각 다르게 하여 농약을 살포했을 때 후류에서의 노즐 유동을 수치해석을 통하여 분석하였으며, 전달되는 액체의 비율을 확률 밀도 함수의 평균 제곱근을 나눈 새로운 성능지수를 이용하여 비교함으로써 작물의 특성에 따른 드론의 농약 살포 가이드라인을 구축하고자 한다. The size and shape of crops are diverse, and the growing environment is also different. Therefore, when one uses a drone to spray pesticides, the characteristics of each crop must be considered, and flight conditions such as the flight height and forwarding velocity of the drone should be changed. The droplet flow of pesticides is affected by various flight conditions, and a large change occurs in the sprayed area. As a result, an uneven distribution of liquid may be formed at the wake, and the transport efficiency will be decreased as well as there would be a risk of toxic scatter. Therefore, this paper analyzes the degree of distribution of pesticides to the crops through numerical analysis when pesticide is sprayed onto the selected three crops with different characteristics by using agricultural drones with different flight conditions. On the purpose of establishing a guideline for spraying pesticides using a drone in accordance with the characteristics of crops, this paper compares the amount of pesticides distributed in the crops at the wake of nozzle flow using the figure of merit, and the sum of transported liquid rate divided by the root mean square of the probability density function.

Road or Railway construction over soft ground is needed to be considered on secondary consolidation which will be caused differential settlement, lack of transport serviceability, higher maintenance cost. Especially for the railway construction in the second phase of Gyung-Bu or Ho-Nam high speed railway, concrete slab track has been adapted as a safe and cost effective geotechnical solution. In this case controlling the total settlement under the tolerance is essential. And pile supported geogrid reinforced construction method is suggested as a solution for the problem of the traditional method on soft soil treatments. Pile supported geogrid reinforced construction method consists of piles that are designed to transfer the load of the embankment through the compressible soil layer to a firm foundation. The load from the embankment must be effectively transferred to the piles to prevent punching of the piles through the embankment fill creating differential settlement at the surface of the embankment. The arrangement of the piles can create soil arching to carry the load of embankment to the piles. In order to minimize the number of piles geogrid reinforced pile supported construction method is being used on a regular basis. This method consists of one or more layers of geogrid reinforcement placed between the top of the piles and the bottom of the embankment. This paper presents several methods of pile supported geogrid reinforced construction and calculation results from the several methods and comparison of them.

샘플링검사를 이용한 PLC의 불량률 추정 및 불량원인 개선 사례연구

WDM(Wavelength Division Multiplexing) is called a wavelength division multiplexing optical transmission method and is a next-generation optical transmission technology. Case company F has recently developed and sold PLC(Planar Lightwave Circuit), a key element necessary for WDM system production. Although Chinese processing companies are being used as a global outsourcing strategy to increase price competitiveness by lowering manufacturing unit prices, the average defect rate of products manufactured by Chinese processing companies is more than 50%, causing many problems. However, Chinese processing companies are trying to avoid responsibility, saying that the cause of the defect is the defective PLC Wafer provided by Company F. Therefore, in this study, the responsibility of the PLC defect is clearly identified through estimating the defect rate of PLC using the sampling inspection method, and the improvement plan for each cause of the PLC defect for PLC yeild improvement is proposed. The result of this research will greatly contribute to eliminating the controversy over providing the cause of defects between global outsourcing companies and the head office. In addition, it is expected to form a partnership with Company F and a Chinese processing company, which will serve as a cornerstone for successful global outsourcing. In the future, it is necessary to increase the reliability of the PLC yield calculation by extracting more precisely the number of defects.
