Usual interstitial pneumonia(UIP) is relatively rare disease of lung parenchyme under the age of 50. Lung cancer is reported to occur as a complication of UIP, but has not been reported in young age patient with UIP in Korea. A 35-year-old man was admitted to the hospital because of dyspnea, cough and mild fever. He had been suffered from dyspnea during 3 years. The dyspnea worsened recent 1 month ago. He had been treated with pneumonia at another hospital during 4 months before this admission. Chest radiographs and High resolution CT showed subpleural and basal dominant reticular opacities in both lung with no change until now. He was smoker and his occupation was car engine-man dealing with benzene. UIP is suspected by history and radiologic findings. Operation for open lung biopsy was performed to obtain lung specimen via video-assisted thoracoscopic surgery. Patient's pathologic examination showed UIP combined with adenocarcinoma in RLL superior segment and posterobasal segment and RLL lobectomy was done. After operation, the patient has been in cancer free condition so far. We report a case of UIP combined with lung cancer in young man with brief review of the literature.

An Ac-type Plasma Display Panel (PDP) operating with Ne-Ar(0.1%) Penning mixture gas is fabicated. The characterics of the panel with electrodes covered with thin and thick dielectric layers are studied. The brightness of the Neon-orange light emitted by the panel measured as function of applied voltage and frequency. As an application, a graphic display system equipped with PDP showing still and moving pictures is made.

We had a result of the treatment as below when is devided Korean medicine Tx.. Western medical Tx., Cooperative Tx.. 1) At the improvement of BP control, an average in Korean medicine Tx. (from 170㎜Hg/100㎜Hg to 150㎜Hg/90㎜Hg), an average in Western medical Tr. (from 170㎜Hg/100㎜Hg to 130㎜Hg/80㎜Hg), an average in Cooperative Tx.(from 180㎜Hg/110㎜Hg to 130㎜Hg/90㎜Hg), generally all pars had improvements of BP control. But it is not significant of each case. 2) At the improvement of symptoms by the apologetics, Cooperative Tx. is profitable in cases of 'GanHwa',' DamEum', 'EumYangYangHer', 'EumHer'. Korean medicine Tx. is superior in case of 'GiChe'. 3) At the improvement of symptoms by a questionnaire, Korean medical Tx., Western medical Tx., Cooperative Tx. groups had improvements, but each practice group didn't have specific significance. Only it was somewhat profitable to Korean medical Tx. in the 210㎜Hg/110㎜Hg, Western medical Tx. in the 180㎜Hg/110㎜Hg, Cooperative Tx, in the 170㎜Hg/90㎜ Hg. 4) There are the apparent improvements in patients whose BP are over 200㎜Hg of Korean medical Tx. group, whose BP are over 190㎜Hg of Western medical Tx. group and whose BP are over 170㎜Mg of Cooperative Tx. group. There are the improvement of diastolic BP in 110㎜Mg(Korean medical Tx., Western medical Tx.) and 90㎜Hg(Cooperative Tx.). 5) At the improvement of Pulse pressure, generally Pulse pressure are decreased. There are similar improvements in all of Korean medical Tx., Western medical Tx., and Cooperative Tx.. 6) At the Symptomatic approvement according to ages, Korean medical Tx., Cooperative Tx. are somewhat good for his twentieth, and Western medical Tx. is somewhat good for his forties. 7) the correlation of Obesity-grade and BP, as Obesity-grade is higher as BP is higher, but there are no similarity in the improvement. 8) At the EAV improvements, as examination into correlation with the point of 1~3th, we could get results as below. There are high improvements of DRHTM, DRALM, DLLYM, DLLIM in Cooperative Tx. There are high improvements of DRPASI, DLLARI in the Korean medical Tx. group. There are high improvements of DRFADM in Western medical Tx. group.
삼각형 폴리곤 곡면의 데이터 구조 및 그 응용에 관한 연구

Highly detailed geometric models are rapidly becoming commonplace in CAD/CAM, computer graphics, and other applications. Polygonal meshes are the most appropriate geometry representation for the complex models. They are flexible enough to represent any arbitrary shapes within any specific tolerance and can be directly rendered even on today's low cost PCs. In this paper, we describe the design and implementation of our face-based data structure for triangulated polygonal meshes. We start by identifying the minimal requirements, time and space efficiency, for triangular mesh data structure in the context of the geometric modeling and processing. Then we explain the details of the data structure and its design intent or features. Next, we give detailed implementations developed for atomic mesh operations with some illustrating figures and examples. Finally, we evaluate the modeling capabilities of our data structure by mesh processing applications such as smoothing, simplification, and subdivision.

The method of maximum entropy is reviewed with emphasis on its relationship to entropy rate, filters, autoregressive processes, extrapolation, the Levinson algorithm and stability. The prupose of this paper is an attempt to explain the interconnection of above topics starting from principles. The effectiveness of this method in the solution of specific problems will not be considered here. This paper is essentially heuristic and main references are A. Papoulis' paper(1981) and text(1991).
VNURBS표현식에 기초한 볼륨 데이터의모델링 및 분석 기법
박상근 충주대학교 2006 한국교통대학교 논문집 Vol.41 No.-
This paper describes the volumetric data modeling and analysis methods that employ volumetric NURBS or VNURBS that represents heterogeneous objects or fields in multidimensional space. For volumetric data modeling, we formulate the construction algorithms involving the scattered data approximation and the curvilinear grid data interpolation. And then the computational algorithms are presented for the geometric and mathematical analysis of the volume data set with the VNURBS model. Finally, we apply the modeling and analysis methods to various field applications including grid generation, flow visualization, implicit surface modeling, and image morphing. Those application examples verify the usefulness and extensibility of our VNUBRS representation in the context of volume modeling and analysis.
