1980년대 건설된 국내 원자력발전소는 30년 정도의 운전 년수를 기록하고 있다. 가동연한의 증가에 따라 원자력발전소에 설치되어 있는 전력케이블은 열화진단 및 유지보수의 필요성이 증대되고 있다. 주기적 안전성 평가(Periodic Safety Review) 및 계속운전과 관련하여서도 고압케이블의 관리방안이 지속적으로 요구되고 있다. 본 논문에서는 원자력발전소에 설치되어 있는 13.8kV 고압케이블의 건전성을 확인하기 위하여 국내 최초 원자력발전소 운전 중 부분방전 진단을 수행하였다. 특히 측정장비별 특성 및 신뢰성을 제고하기위하여 Techimp사의 PD-Base I 장비와 OMICRON사 MPD600 장비 두가지를 가지고 케이블 부분방전(Partial Discharge; PD)열화진단을 수행 하였고 결과를 비교하였다.

Hypothalamic hamartoma[HH] is an unusual nonneoplastic developmental lesion associated with gelastic epilepsy and precocious puberty, mostly found in children. Although open surgery has been attempted when antiepileptic medication failed to control seizures, its deep location and surrounding vital structures often rendered surgery unsuccessful. We describe the outcome of gamma knife radiosurgery in three children with a HH associated with gelastic epilepsy and reviewed the literature for a possible therapeutic mechanism.

The purpose of this study is to clarify the relationship between the behavior of appreciation and spatial configuration in museum, to concentrate upon the difference that is happened according to composition method of convex space. The subject of this study are as follows: 1) The change of spatial configuration by specialization from architectural space to exhibition space in museum. 2) The variety of spatial configurations that is happened according to connectivity condition of the spatial configuration 3) The relationship between the size of convex space and the behavior of appreciation

The purpose of this study was to investigate main ingredients of Hwangtoh (Korean yellow ochre), especially ferric oxide $(Fe_{2}O_{3})$ content. In this study, X-ray fluorescence spectrophotometry was employed to analyze the ingredients of Hwangtoh. The ferric oxide $(Fe_{2}O_{3})$ contents of Hwangtoh from Hwa Sun, Ham An, Chil Gok, Sun Chun, Ha Dong, San Chung, Go Chang, Kim Che and Jeong Eup were 1.5, 5.66, 11.76, 6.63, 2.74, 11.4, 4.84, 7.21 and 6.23%, respectively. Based on the above results, any Hwangtoh sample didn't meet the ferric oxide $(Fe_{2}O_{3})$ content criterion.

This paper is concerned with the following Kirchhoff-Schrödinger-Poisson system $$\begin{cases} -(a+b{\displaystyle\smashmargin{2}\int\nolimits_{\mathbb{R}^3}}{\mid}{\nabla}u{\mid}^2dx){\Delta}u+V(x)u+{\mu}{\phi}u={\lambda}f(x){\mid}u{\mid}^{p-2}u+g(x){\mid}u{\mid}^{p-2}u,&{\text{ in }}{\mathbb{R}}^3,\\-{\Delta}{\phi}={\mu}{\mid}u{\mid}^2,&{\text{ in }}{\mathbb{R}}^3, \end{cases}$$ where a > 0, b, µ ≥ 0, p ∈ (1, 2), q ∈ [4, 6) and λ > 0 is a parameter. Under some suitable assumptions on V (x), f(x) and g(x), we prove that the above system has at least two different nontrivial solutions via the Ekeland's variational principle and the Mountain Pass Theorem in critical point theory. Some recent results from the literature are improved and extended.

After providing the purpose, scope and methods of present study in the first chapter. the second chapter discusses a theoretical overview on the social implication of medical expenditure and the medical insurance program for the aged population. In conclusion, to realize the reduction of aged population's medical expenditures, some possible plans are conceivable. Firstly, the payment level of medical insurance should be upgraded and the insurance coverage in oriental medicine treatment and the drug-store protection program need to be implemented. Secondly, the medical facilities and man-power have be expanded for the sake of reducing the social and geographical distances the aged population has to overcome to receive the medical benefits. Thirdly, the expansions of medical services for the home-stay aged are all the more required. Finally, a wide range of programs needs to be augmented to promote health for the aged population.

The purpose of this study is to provide the direction of the policy forwelfare of the home - based service by identifying the problem and improvement of the home - based service. In the fast growing society like korea social welfare policy for the home - based service. The core hypotheses, of this research that home - based services canexpand social support network and improve life satisfaction were aceptedor rejected, In other words, while the home - based services expanded the lold people social support network through the activities of social workers and volunteers, these services considering the findings of the this study, we can conclude that the current home - based services provided by social welfare have an effect upon increasing old peoples social support. But these services have no effect upon improving life satisfaction index.

Noninvasive detection of patients with probable Alzheimer's disease (AD) is of great importance for assisting a medical doctor's decision for early treatment of AD patients. In the present study, we have extracted quantitative electroencephalogram (qEEG) variables, which can be potentially used to diagnose AD, from resting eyes-closed continuous EEGs of 22 AD patients and 27 age-matched normal control (NC) subjects. We have extracted qEEG variables from mean phase coherence (MPC) and EEG coherence, evaluated for all possible combinations of electrode pairs. Preliminary trials to discriminate the two groups with the extracted qEEG variables demonstrated that the use of MPC as a supplementary or alternative measure for the EEG coherence may enhance the accuracy of noninvasive diagnosis of AD.
