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.

The definition and utilization of curvilinear coordinate system is one of the important topics that are necessary to formulate the physical laws with relative easy and also to cope with the difficulties in applying numerical techniques and algorithms to irregular domains or complex geometries. The choice of a suitable curvilinear coordinate system enables to significantly simplify the solution procedure and to obtain the numerical solution with less sensitive truncation errors. In this paper, we present a method for representing and computing generalized curvilinear coordinate system with non-rational trivariate B-spline volume. We start by introducing its mathematical formulation for the construction of curvilinear coordinate system. Then we describe the computational algorithms concerning the internal structures of the curvilinear coordinate system in terms of our representation form. Next we explain the details of the construction algorithms, data fitting with curvilinear or scattered data. In addition, we give grid generation examples to show the capabilities of our representation with some illustrating figures. Finally, we remark on the potential of our representation scheme extended to integrate with all geometric shapes and their internal physical attributes.

This paper proposes a generalized NURBS model, called Volumetric NURBS or VNURBS for representing volumetric objects with multiple attributes embedded in multidimensional space. This model provides a mathematical framework for modeling complex structure of heterogeneous objects and analyzing inside of objects to discober features that are directly inaccessible, for deeper understanding of complex field configurations, The defining procedure of VNURBS, which explains two directional extensions of NURBS, show VNURBS is a generalized volume function not depending on the domain and its range dimensionality, And the recursive algorithm for VNURBS derivatives is described as a computational basis for efficient and rebust volume modeling. In addition, the specialized versions of VNURBS demonstrate that VNURBS is applicable to various applications such as geometric modeling, volume rendering, and physical field modeling.

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.

An eleven year old castrated male Maltese was presented to the Veterinary Medical Teaching Hospital of Chungnam National University. In physical examination, approximately 0.5 cm round mass was observed on tail base. This small elevated mass has also shown alopecic and firm configuration. It was differentially diagnosed as sebaceous adenoma and hyperplasia by fine needle aspiration. After surgical removal, the sample was diagnosed as sebaceous hyperplasia by histopathological examination. It has not yet shown any signs of recurrence and prognosis has teen good.

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.
