  • In this paper, we prove common fixed point theorems for occasionally weakly compatible maps in Menger spaces with a continuous t-norm of H-type. As application to our results, we obtain the corresponding fixed point theorems in metric spaces. Our results improve and generalize many known results in Menger spaces as well as in metric spaces.

  • Previously, Park et al. (2005) defined an intuitionistic fuzzy metric space and studied several fixed-point theories in this space. This paper provides definitions and describe the properties of type(${\beta}$) compatible mappings, and prove some common fixed points for four self-mappings that are compatible with type(${\beta}$) in an intuitionistic fuzzy metric space. This paper also presents an example of a common fixed point that satisfies the conditions of Theorem 4.1 in an intuitionistic fuzzy metric space.

  • A common fixed point result of Gregus type for subcompatible mappings defined on a complete linear metric space is obtained. The considered underlying space is generalized from Banach space to complete linear metric spaces, which include Banach space and complete metrizable locally convex spaces. Invariant approximation results have also been determined as its application.

  • 코로플레스 지도는 지리사상의 지역간 분포 특성을 시각적으로 표현하는 지도이다. CMS는 코로플레스 지도 제작 프로그램으로 1988년에 처음 개발되었다. 본 연구에서는 최근 변화된 컴퓨터 기술과 사용자 환경을 고려하여 이에 적합한 CMS ll를 개발하였다. CMS ll는 IBM PC AT또는 상위 기종에서 실행되며 DOS 5.0 이상의 운영환경과 최소 640KB 이상의 메모리가 필요하다. 그래픽 해상력과 색상을 고려하여 그래픽보드로 VGA를 사용하고 고해상도의지도를 출력하기 위해 HP 호환의 레이저 ? 프린터를 지원한다. 코로플레스 지도를 효과적으로 디자인하기 위해 메뉴와 지도의 제목과 범례 등을 한글화하였고 한자의 사용도 가능하도록 제작하였다. 속성자료의 호환을 위해 DBF형식을 이용하였다.

  • Radiologic findings of Bing-Neel syndrome, which is an extremely uncommon complication resulting from malignant lymphocyte infiltration into the central nervous system (CNS) in patients with Waldenstr$\ddot{o}$m's macroglobulinemia (WM), have been infrequently reported due to extreme rarity of the case. A 75-year-old man with WM presented at a neurology clinic with progressive gait and memory disturbances, and dysarthria of 2 months duration. Cerebrospinal fluid and serum protein electrophoresis and immunofixation electrophoresis showed IgM kappa-type monoclonal gammopathy. Brain magnetic resonance imaging revealed multifocal, hyperintense lesions on T2 weighted-images. Brain diffusion-weighted imaging (DWI) demonstrated hyperintensities in cerebral and cerebellar lesions that appeared isointense on apparent diffusion coefficient maps, which were compatible with vasogenic edema. Although histologic analysis is a confirmative study to prove direct cell infiltration into the brain, brain MRI with DWI may be a good supportive study to diagnose Bing-Neel syndrome.
