In recent years, tunnel construction is being increased in order to resolve traffic congestion around urban area, howeverthere are a lot of difficulties due to restrictions such as interference with existing alignment, adjacent structures andcost increase of land acquisition as well as public complaints for negative environmental impacts near the expectedtunnel construction site. Therefore, applications of close parallel tunnel have been increasing greatly. But close paralleltunnels cannot guarantee the stability compared with normal parallel tunnel which has enough distance between tunnels. So various methods to strengthen the pillar have been introduced recently, however there is few methods which considerthe pillar behaviour in the state of compression. In this paper, the reinforcement methods which reflect the behaviorof pillar were reviewed with comparision and analysis by numerical method.

김제경,김나영,김용욱 대한재활의학회 2017 Annals of Rehabilitation Medicine Vol.41 No.2

Objective To identify predictors for depressive mood in geriatric patients after traumatic brain injury (TBI).Methods A retrospective review of patients’ medical charts was performed in TBI patients who were older than 60 years and referred to the Department of Rehabilitation Medicine at Severance Hospital in 2002–2016. The patients were classified into two groups based on the Geriatric Depression Scale (GDS): non-depressive group (0≤GDS≤16) and depressive group (17≤GDS≤30). Data was collected on demographic, socioeconomic, comorbidities, and trauma-related factors, as well as the pathophysiology of TBI, localization of lesion, post-traumatic complications, functional level, and cognitive and linguistic function. Significant variables from univariate analysis were analyzed using logistic regression.Results Forty-two patients were included, of whom 64.3% displayed a depressive mood. Patients in the depressive group had higher comorbidity scores (p=0.03), lower Functional Independence Measure (FIM) totals (p=0.03) and FIM motor (p=0.03) scores, higher modified Rankin Scale scores (p=0.04), and frequently had a bilateral or left side brain lesion (p=0.002). Higher comorbidity scores (odds ratio [OR], 1.764; 95% confidence interval [CI], 1.047–2.971), bilateral lesions (OR, 13.078; 95% CI, 1.786–95.780), and left side lesions (OR, 46.074; 95% CI, 3.175–668.502) were independently associated with a depressive mood in the multiple logistic regression analysis.Conclusion The risk of depressive mood in geriatric patients after TBI is associated with comorbidity, functional limitation, and the horizontal distribution of brain lesions. The most significant determining factors were comorbidity and the horizontal distribution of brain lesions. Early detection of risk factors is important to prevent and manage depressive mood in geriatric patients after TBI.

英國에 있어서 中産階層의 政治參與에 관한 硏究 : 第1次 選擧法改正을 中心으로

金濟璟 東亞大學校 1982 東亞論叢 Vol.19 No.1

In england, Constitutional government had been formed through 17 Century's Revolution which had enforced to turn over Sovereign power of the king to the Parliament. Even though constitutional government had been formed that government was called constitutional monarchy, limited monarchy and mixed monarchy, because the driving power was established by agreement between the noble classes of the great landlords and top classes of the bourgeoisie, and according to king's abilities the king was able to strenthen his authority by controlling leading classes. Like this, the existence of the king had kept the nobles of the great landloards cling to their advantageous position. Addition to that, in the 18 century, even the power shifted from the great feudal lords to the noble of landlords, the nobles were still keeping their traditional prestiges and wealth, and the middle classes did not internene in. Consequently, during the period of 18 century to the early 19 century gentry took powerful roles in the parliament. On the other hand, economic development brought lots of changes. Bourgeoisie had grown up, and top of that classes had invested in land who become gentry-like. Thus, landlords and top classes of the bourgeoisie became the ruling classes of the society, and by the result, the cabinet government had developed. Particularly, rapidgrowth of industrial bourgeoisie, who were accelerated by the Industrial Revolution, motivated them to start participaion-movement in politics. In the later 19 century, in spite of temporary interruption by the French Revolution and Nopoleon's war, the development of this movement continued systematically. Up to 1830's, the election law containing "the spoiled or Closed franchise" which was established in 1430 had been applied in the election without major reform to give favours to the ruling classes. Therefore the middle classes and the working classes formed an united front to develop the movement of reformation of the election law. But, the ruling classes had ignored the demands of the united front and the ruling classes reformed the election law to be advantageous to them. In the process, there were many disputes over the matters of qualification for an election, distribution of parliament sets, registration system etc. One notable consequence of the controversy between the nobles and the workingclasses was the historical reformation in 1832. By that result, the electoral roll increased 50% more, spoiled electoral distric disappeared by the redistribution of the parliamentry seats, and the gate was opened for the middle classes to participate in politics. By the way, even the middle classes and working classes worked together to reform the election law, the new reformed law not expanded enough to allow the working classes participating in politics. Thus the working classes separated themselves from the united front, and they explored their own ways to achieve their purposes. That efforts continued until later part of 19 century. On the other hand, systematical establishment of election had developed poltical parties and pressure groups which were essentially needed in the process of application of the system. As it is mentioned above, the reform of the election law of 1832 was inevitable, and since that reform there were several other reforms until later part of 19 century to expand the social foundation of parliamentarism. Under that situation, bourgeoisie had been establishing classical democratic form of government as they compromising with noble classes of landlords.

Recently, interest in the safety and maintenance of the structures is growing. However, due to the low-cost order placed by the orderingorganization, the safety diagnosis specialized institution becomes insolvent and many problems have arisen due to insufficient inspection and diagnosis. Therefore, in this study, the current status of bid cost was examined through the survey of the practitioners and case analysis. As a result, Precisionsafety inspection is deemed that it is necessary to increase the efficiency of the criteria cost and to strengthen the rigidity of the criteria cost ratherthan adjusting the criteria cost. Precision safety diagnosis, the criteria cost for structures with a floor area of less than 10,000 ㎡ is lowered to 80 %from the current standard. For structures larger than that, the current criteria cost are applied, but it is deemed necessary to strengthen the rigidityof the criteria cost. 본 연구는 시멘트 모르타르속에 매입된 철근주위가 건조될 때 불안정한 전류분포의 영향을 측정하고, 교류 임피던스 특성변화에대한 영향을 고찰하는 것을 목적으로 한다. 건조과정중 철근의 전기화학적 반응을 측정하기 위해, 두 개의 철근이 매입된 3개의 시멘트 모르타르가 실험을 위해 준비되었다. 주요 변수는 20mm 모르타르 두께를 동일하게 가지도록 하여, 두 철근사이의 간격이 10, 20과 30mm가 되도록하였다. 해양환경에서 콘크리트 구조물속의 철근 부식속도를 가정하기 위해서, 3개의 모르타르 시험체는 15 사이클의 침지-건조환경(해수에서 24시간 침지와 48시간 실온 건조)에 노출되었다. 부식전위의 변화는 건조중에 용존산소의 확산속도 증가로 인해 귀한 방향으로 이동하는것이 관찰되었다. 침지-건조환경에서 교류 임피던스는 100kHz에서 1mHz까지 측정되었다. 철근과 모르타르사이의 계면상태를 설명하기 위해 이론적 모델이 제안되었으며, 그것은 용액저항, 전하이동저항과 CPE로 구성된 등가회로를 사용하였다. 철근의 부식이 진행됨에 따라, 저주파수 영역에서 확산 임피던스가 나타났다. 침지-건조 환경중 건조과정에서 이송차가 45o에 가까워지는 현상으로써 전류분포가 불균일해지는 경향을 보였다.
