공동체주의(Communitarianism)의 공동체 개념과 의미에 대한 비판적 고찰
유종원 전남대학교 사회과학연구소 1998 현대사회과학연구 Vol.9 No.1
This paper critically reviews the concept of community being used in Communitarianism which regards the community as the good in relation to individuals. Communitarians criticize liberalism for its limits in achieving the community, which emphasizes the voluntary willingness to participate. Community, they maintains, can be constituted not by the free will to participate but by the situated self and self reflection as a member of community The concept of community by Communitarians, however, seems to over-estimate on the human ability for self reflection, the conflict of social justice between the communities with different cultural values, under-estimate the interaction of self reflection and attachment, and is short of answering these questions. Communitarian philosophy has been attractive to Korean society with strong community tradition. Not to be overlooked, however, is that Communitarianism in based on Western individualism A hasty import of it may lead to one-sided emphasis on the affective meaning of community.
다중 Ridge 원형 도파관의 TM과 TE 모우드 해석
유종원,명노훈 한국전자파학회 1996 한국전자파학회논문지 Vol.7 No.5
The multiple-ridged circular waveguides is analyzed using Fourier series and the mode matching technique. The enforcement of the boundary conditions yields the simultaneous equations for the field coefficient inside the waveguides. The simultaneous equations are solved to represent a dispersion relation in an analytic series form. The numerical computation is performed to illustrate the behavior of the cutoff wavenumbers in terms of number, length and angle of ridges. The presented series solution is exact and rapidly-convergent so that it is efficient for numerical computation. A simple dispersion relation based on the dominant mode analysis is obtained and is shown to be very accurate for most practical applications. 다중 ridge 원형 도파관을 퓨리에 급수 전개와 모드 정합법을 이용하여 정확하게 해석하였다. 경계 조건을 이용하여 두 급수식을 전개하고 이를 풀어 모드를 정확하게 구하였다. 다중 ridge 원형 도파관의 ridge의 수, 길이, 폭에 따른 차단 파수(cutoff wavenumber)의 변화를 살펴보았다. 구한 해는 정확하고 수렴성이 뛰어나며 dominant mode에 대해서는 간단한 근사식을 제시하였다.

Canine skin is a highly dynamic organ that is constantly adapted to changes in its environment. It provides structural, sensory, immunologic, and physiologic functions and contributes an essential barrier function against potential environmental insults. We assessed the changes of canine skin hydration, pH, and protein contents by noninvasive method according to the frequency of application with canine commercial shampoo. Canine commercial shampoo was applied topically every other day, 5 days, and 8 days on different sites, respectively in 8 dogs. Saline-applied site was as a control. Skin hydration was increased and skin surface pH was decreased significantly in canine commercial shampoo-applied site every other day (p < 0.05). Also, skin protein concentration measured by D-squame® tape stripping method was increased significantly in canine commercial shampoo-applied site every other day (p < 0.05). There were alterations on every 5 days and 8 days, but not significantly. These results may be recognized that the frequent use of canine commercial shampoo cause abnormalities of the skin barrier function and alteration of stratum corneum integrity/cohesion. Consequently it was suggested that bathing the dog with canine commercial shampoo was appropriate every 5 or 8 days.
