[1]에서 LCZ 수열군의 2배 확장을 제안하였다. 본 논문에서는 [1]에서의 2배 확장방법을 일반화하는 새로운 확장방법을 제안한다. 이 생성방법을 사용하면 인수가 (N,M,L,ε)인 q진 LCZ 수열군은 인수가(pN,pM,p「(L+1)/p」-,pε)인 q진 LCZ 수열군이 된다. 이 때, p는 소수이고 p는 q의 약수다. 특히 L≡p-1modp 일 때, 확장된 q진 LCZ 수열군의 인수는 (pN,pM,L,pε)이 된다. In this paper, a new extending method of q-ary low correlation zone(LCZ) sequence sets is proposed, which is a generalization of binary LCZ sequence set by Kim, Jang, No, and Chung. Using this method, q-ary LCZ sequence set with parameters (N,M,L,ε) is extended as a q-ary LCZ sequence set with parameters (pN,pM,p「(L+1)/p」-1,pε), where p is prime and p|q.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

It was well documented that in the course of development of rat tibia in formation of cartilage model from the mesenchymal cells and subsequent ossification generally starts as early as 15-16th day of embryonic stage and that development of tibia completes by the 8-10th day after birth. Rather extensive studies have been made on the differention of cartilage cells, including their secretory activities of matrix and composition of matrix as well. However, there are still much to be clarified on the more precise feature of differentiation and growth of epiphyseal plates in the rat tibia. Therefore the present study was designed to explore differentiation of epiphyseal plate biochemically and histologsically at each developing stage of rat tibia. The albino of Wistar strain were used as experimental animal. And expreimental animals were sacrificed at 16, 18, 20th of fetal life and 2nd, 4th and 10th day of neonatal life. The epiphyseal plates were removed from tibia and were fixed in 10% formalin and 2% glutraldehyde-2.5% paraformaldehyde phosphate. The PAS-hematoxylin stain was carried out for the study of general development of tibia and alcian blue (1.0), alcian blue (2.%) and aldehyde fuchsin-alcian blue stains for the determination of mucopolysaccharide variations. Also, thin sections were prepared and stained with uranyl acetate and lead citrate stain for the ultramicroscopic study of chondrocytes and matrix of epiphyseal plates at different stages of development of rat tibia. The results obtained were as fokkows: 1. A small amount of acid unsulfated mucin was found in the matrix of epiphyseal plate as early as 16th day of fetal life. 2. On the 18th day of fetal life existance of acid mucin and sulfated mucin were recognized in the matrix of epiphyseal plate and thereafter they were increased in amount. 3. The acid mucin reached maximum level at 2nd day of neonatal life and thereafter sulfated mucin gradually appeared in the mathix of epiphyseal plate. 4. In the proliferative zone of tibia of 18day old embryo, secretary granules were deposited in the all membranes of chondrocyte. As the fetus grew, the namber and size of secreted granules were increased approprocial by increase in salfated mucin: And the rough endoplasmic reticulum in the chondrocytes was increased also. To summerize above results the acid mucin start to appear in the matrix of epiphyeal plate as ealry as 16th day of fetal life and later a part of acid mucin is changed to neutral sufated mucin, the secretary granules observed on the cell membrane of chondrocytes of 12 day old embryo seems to be sulfated mucin.

We designed two aspheric objective lenses(N.A=0.54915 and N.A=0.46764) for optical disk drive by DLS optimizing method and obtained that least spot size is 1㎛ and Strehl Ratio is 0.98. The glasses of objective lenses are light and have low thermal variation. This lenses have the performance of diffraction limit. Therefore, it is used the optical unit of magneto optical disk drive system.

This study was conducted to investigate the pasting properties of waxy corn ‘Ilmichal’ during ripening with different sowing date. Starch content of Ilmichal was increased as matured (p<0.05). Analysis of pasting properties with waxy corn starch using a rapid visco analyser (RVA) showed linear changes in peak viscosity, trough viscosity, final viscosity, breakdown and consistency according to ripening. There were significantly positive correlation between starch content of Ilmichal and peak viscosity (0.39*), trough viscosity (0.58***), final viscosity (0.58***), and consistency (0.57**). Differential scanning calorimerty (DSC). The enthalpy of gelatinization was increased as ripening. But onset and peak temperature were decreased. There were significantly positive correlation between starch content of Ilmichal and onset temperature (0.44*), peak temperature (0.38*), and completion temperature (0.59***), on the other hand, crude protein content presented significantly negative correlation between completion temperature (-0.41*).

The dissociation constants of 2-, 3- and 4-acetylpyridine were measured by conductometric method in the temperature range from 15 to 40℃ and pressure up to 2,500bar. The dissociation constants of these substituted pyridines were increased as the temperature increase but decrease as the pressure. From the data thermodynamic properties were calculated and the Hammett plat were obtained. From these properties the characteristic properties of the dissociation reaction were discussed.

The study was to develop a Korean college student version of the Psychoeducational Intervention Program for unipolar depression originally developed by Lewinsohn et. al. (1982). In addition, the study was to find the effectiveness and any procedural problems for the application to the college students in unipolar depression. In order to achieve the above purposes, seven college students among volunteers were selected in terms of Beck Depression Inventory (BDI) and Depression scale of MMPI(MMPI-D). All the subjects scored above 70 points of T-score on MMPI-Depression scale, below 60 points of t-score on MMPI-Mania scale, and also above 16 points on BDI. The original program by Lewinsohn et. al. (1982) was translated and revised to seven session program for college students and also reconstructed the related materials which were workbooks and activity tasks. Examining the effectiveness of the program to the college students, pre- and post- tests of BDI and MMPI-D were given. The results showed that there were significant reduction of post- test scores of BDI and MMPI-D. Therefore, the program was confirmed to be effective for the college students in unipolar depression. The main procedural problems implementing the program was how to make students in depression actively follow and motivate in the procedures of the program.

A model for off-site radiological dose evaluation due to liquid effluents generated from the operation of nuclear facilities, which are located in inland area, was developed in consideration of Korean agricultural and environmental conditions. In addition, sensitivity analysis was performed for the improvement of the model. Using the developed model, test runs for nuclear fuel fabrication facilities were conducted. Five kinds of exposure pathways(vegetation, animal products, drinking water, fresh-water-fish, shoreline deposits) and two kinds of radionuclides(234U, 234Th) were considered. Sensitivity analysis for input parameters of the model was conducted by applying a Monte Carlo method with Latin Hypercube Sampling (LHS) technique. As the results, the ingestion of irrigated agricultural products was the highest contributor among the considered exposure pathways. Major sensitive input parameters for the results were the ratio of the interception fraction to the yield of agricultural plants and the human consumption rate.
