Wang-Qu [9]는 패턴 인식, 이미지 처리, 근사 추론, 퍼지 제어 등 다양한 분야에서 광범위하게 적용할 수 있는 애매한 소프트 집합의 엔트로피, 유사성 측도 및 거리 측도를 도입했다. 또한, Jang-Kwon [3]에서 처음으로 구간값 함수의 쇼케이 적분을 정의하고 이와 관련된 성질을 조사하였다. 그이후 많은 논문에서 구간값 쇼케이적분의 응용을 연구해 왔다. 애매한 집합의 속성이 구간값 소속함수의 성질을 가지고 있음을 이용하고자 한다. 본 논문에서는 애매한 소프트 집합상에서 쇼케이 적분을 정의하고, 이들 적분에 의해 정의된 구간값 거리 측도를 조사한다. Wang-Qu [9] introduced entropy, similarity measure and distance measure of vague soft sets which can be extensively applied in many fields such as pattern recognition, image processing, approximation inference, and fuzzy control. In addition, for the first time in Jang-Kwon [3], the Choquet integral of the interval-valued function was defined and the related properties of them were investigated. Since then, many papers have studied the application of interval-valued Choquet integrals. We note that vague soft sets have the interval-valued membership functions. In this paper, by using interval-valued Choquet integrals and vague soft sets, we define the Choquet integral on vague soft sets and investigate an interval-valued distance measure defined by them.

Keratins are characteristically present in all keratinizing and nonkeratinizing epithelial cells and their neoplasms. They consist of at least 19 different polypeptides ranging from 40 to 69 kilodaltons, which are developmentally related to specific epithelial cell types. Keratins of high and intermediate molecular weights are readily demonstrated in squamous cell carcinomas, which are characteristically rich in tonofilaments and tonofilament-desmosome complexes. Keratins of low molecular weights are expressed in adenocarcinoma including renal cell carinoma, hepatocellular carcinoma, small cell carcinoma, and carcinoid tumor. These tumors do not reveal any tonofilaments and sacrcely show discrete filaments on electron microscopy. An immunoperoxidase technique employing antibody to keratin was used to study distribution and staining pattern of keratin filaments in benign and malignant epithelial tumors (20 squamous cell carcinomas, 20 gastric adenocarcinomas, 20 transitional cell carcinomas and 15 non-neoplastic epithelia). These immunohistochemical results were compared with ultrastructural features of neoplastic diagnosis of squamous cell carcinoma, adenocarcinoma and transitional cell carcinoma, and estimation of degree of differentiation. The results are as follows : 1. The squamous epithelium, glandular epithelium and transitional epithelium disclosed the positive reaction for keratin. 2. Squamous cell carcinoma and transitional cell carcinoma exhibited positive reaction for keratin. 3. Gastric adenocarcinoma showed uniformly negative or weakly positive reaction for keratin. 4. On electron microscopy, heavy bundles of tonofilaments and desmosomes were more frequently encountered in well differentiated squamous cell carcinoma, In poorly differentiated squamous cell carcinoma, a few tonofibrils and desmosome were noted. 5. In the adenocarcinomas, the intermediate filaments were arranged randomly as nonaggregated, short filaments spread throughout the cytoplasm, although occasionally they formed a perinuclear whorl. These filaments did not become aggregated to form tonofilaments. 6. On the immunogold labeling for keratin of low molecular weight areas in gastric adenocinoma, in tense labeling of intermediate filaments for keratin was noted. From the above result, ultrastructural and immunohistochemical study on malignant epithelial cell were useful in differential diagnosis of squamous cell carcinoma, adenocarcinoma and transitional cell carcinoma, and estimation of degree of differentiation. It was also proved that immunogold labeling technique was especially valuable for diagnosis of vague case which showed negative or weakly positive reaction in immunohistochemical stain.

Recently many devices print electronic images in a variety of ways. The reproduced color, however, is different from the original color because of the difference of hardware characteristics. To maintain device independent color, gamut mapping method is proposed. The proposed color gamut mapping uses nonlinear intensity mapping and clipping for saturation mapping on HSI color space. In the dithering operation, expanded nonlinear ordered dithering and modified error diffusion are proposed. The proposed ordered dithering uses expanded nonlinear quantization which considers overlapping phenomena of neighbored printing dots. In the modified error diffusion, quantization error to be diffused are adjusted to improve both image blur and color change produced in the error diffusion. So, the printed image is similar to the image of monitor. Our results indicate that proposed algorithm can produce high quality image in the low bit color devices.

Fuzzy sets are a mathematical concept proposed by prof. L. A. Zadeh in 1965. In this paper, we introduce the theoretical study of fuzzy sets and its application. And also we investigate some definitions of fuzzy inferences and some examples of fuzzy expert systems. I hope that those who want to learn about fuzzy theory for practical purposes are interested in this paper.

One of the primary functions for which bones have evolved is to act as structural support. To achieve this goal, bones are remodeling throughout life so that their structure remains optimal for the prevailing mechanical environment. Bone remodeling consists of an initial phase of osteoclastic bone resorption followed by a bone formation period. Prostaglandins are potent regulators of bone formation and bone resorption that can have both stimulatory and inhibitory effects. Elevation of intracellular cAMP is an important intracellular signaling mechanism involved in the regulation of the expression of many proteins. In this study, the author examined whether PGE_2 or DBcAMP affected osteoblastic activation or osteoclastic differentiation in mouse bone marrow cells and osteosarcoma ROS 17/2.8 cells. The effect of PGE_2 and DBcAMP on the cell proliferation was measured by the incorporation of [^3H]-thymidine into DNA. From the result, PGE_2( 0.5-1 ㎍/ml ) and DBcAMP(0.1-0.5 mM) inhibited the [^3H]-thymidine incorporation into DNA. The effect of PGE_2 and DBcAMP on the induction of alkaline phosphatase(ALP) was investigated in ROS 17/2.8 cells cultured in medium containing 0.4% fetal bovine serum. PGE_2 and DBcAMP stimulated ALP activity in the cells. PGE_2 also increased the intracellular cAMPs contents with a maximal effect at 0.5 ㎍/ml. ROS 17/2.8 cells released nitric oxide upon stimulation of PGE2 or DBcAMP with interferon-γ. PGE_2 and DBcAMP increase the phosphorylation level of CREB(cAMP response element binding protein) without any change on the amount of CREB protein. Also, PGE_2 (10^-6 M) and DBcAMP (10^-4 M) significantly increase the generation of osteoclast-like cell in mouse bone marrow cell culture system. In conclusion, the results of this study suggested that PGE_2 and cAMP should appear to be an important regulatory molecule in the processes of bone formation and resorption.

Ion exchange performance to remove nitrate in water was studied using commercially available strong base anion exchange resin of Cl^- type in the batch reactors. Anion exchange resin was more effective than activated carbon or zeolite. With large resin amount or high temperature or low initial concentration, nitrate removal characteristics for a typical gel-type resin was increased. The curves showed the generally accepted selectivity sequence as SO₄^2-$gt;NO₃^-$gt;NO₂^-$gt;HCO₃^-.
