Purpose: Scintillation Proximity Assay (SPA) does not require the physical separation of receptor bound form from free form. SPA was applied to the study of interaction of human chorionic gonadotropin (hCG) and $anti-{\alpha}$ hCG in serum. Materials and methods: $Anti-{\alpha}$ hCG was biotinylated for the binding to streptavidin. The assay was based on the simple competitive binding method between $[^{125}I]hCG$ and the hCG in sample serum, with $anti-{\alpha}$ hCG-coated beads. Aliquots of biotinylated $anti-{\alpha}$ hCG were dispensed into scintillation vials containing $100{\mu}{\ell}\;[^125}I]hCG\;and\;200{\mu}{\ell}$ of either a standard concentration of hCG for preparation of standard curve or unknown sample, and incubated for 20 min. at room temperature. Then $20{\mu}{\ell}$ streptavidin-coated beads were added to vials, and finally incubated for 10 min at room temperature. Values for unknown samples were then calculated from the standard curve. Results: Optimal background counts were certificated using varied radioactivity of radionuclides. Appropriate standard curve was obtained from SPA method successively, and the concentration of hCG from unknown serum was determined by standard curve. The result from SPA assay was similar to that of RIA. Conclusion: This observation confirms that SPA method could be useful for clinical diagnosis.

The great development of the modern science enables the information technology including computer to be promoted, which has the great effects on the whole design field. Most of all, the computer has the feature to express the mathmatical formular through the logic and system, which is being used very efficiently in the design work. CG application to the two-dimensional design may be limited in promoting the basic ability synthetically through the direct and molding experience for its attribute, however, it is possible to create the effects on the different level in addition to those from the traditional skill. In particular, we should keep the fact in mind that the CG application in the design field will be able to accomplish the object only under understanding the attributes and functions for it to have. We should carry out the task to agree with. First, it is necessary to develop the various study on the educational environment to make the process to solve the problems and to promote the effects of the educational media in teaching design with the CG application. This study would make plans to approach that the computer can be utilized for the main method to create design despite of being limited in some point. Moreover, it suggests the possibility for the CG application in the course of building up and motiving the models by applied the basic system, which enables the computer to be applied centering around the composition of geometry pattern of the basic course of the two-dimensional design.

This study was performed to investigate the effects of hCG treatment on pregnancy and delivery rates in the Hanwoo recipients. There were significantly higher pregnancy and delivery rates in the recipients treated with hCG at 7 days after artificial insemination (p<0.05), respectively. The SCNT embryos from bovine fetal fibroblast cells were transferred into the synchronized recipients. The recipients were administered saline (n=89) or hCG (1,500 IU) (n=48) at 7 days after heat, respectively. The pregnancy rate was significantly higher in the recipients treated with hCG compared to that of saline treated group (p<0.01), however, the delivery rate was not different in both treated groups. The concentration of plasma progesterone (P4) was not different in both groups before hCG treatment, but the P4 level was increased significantly in hCG treated group after hCG injection (p<0.05). Although the pregnancy rate was very high in early stage of pregnancy, it was decreased dramatically after 50 days of pregnancy and maintained basal level. Taken together, the treatment of hCG in the SCNT recipients after day 7 of heat was effective method to increase the P4 concentration and to increase the pregnancy rate. But it did not affect directly to delivery.

Cymbidium goeringii is one of the most important and popular species in the orchid family in north-east Asia. In the present study, we prepared multiplex PCR system, and used it for the genotyping of eight simple sequence repeats (SSR) markers (CG409, CG415, CG709, CG722, CG787, CG1023, CG1210, and CG1281) in subject with 40 samples of cultivated varieties. All the analyzed samples showed different combined genotypes. The average combined power of discrimination was very high value of $7.14{\times}10^{-10}$, and observed heterozygosity (Ho = 0.466) was similar with two wild populations of C. goeringii, which may indicate no or little occurrence of genetic change after collection from wild habitats. The present study also developed a two-dimensional barcode to express information of genotype results of eight SSR markers (SSR DNA ID). The discrimination power of DNA ID between two individuals will be statistically more than 99.999999%. The SSR DNA ID and two-dimensional barcode may be very usefully applied for the discrimination and maintence of cultivars of C. goeringii.

In this study, we shall be concerned with computing in parallel a few of the smallest eigenvalues and their corresponding eigenvectors of the eigenvalue problem, $Ax={\lambda}Bx$, where A is symmetric, and B is symmetric positive definite. Both A and B are large and sparse. Recently iterative algorithms based on the optimization of the Rayleigh quotient have been developed, and CG scheme for the optimization of the Rayleigh quotient has been proven a very attractive and promising technique for large sparse eigenproblems for small extreme eigenvalues. As in the case of a system of linear equations, successful application of the CG scheme to eigenproblems depends also upon the preconditioning techniques. A proper choice of the preconditioner significantly improves the convergence of the CG scheme. The idea underlying the present work is a parallel computation of the Multi-Color Block SSOR preconditioning for the CG optimization of the Rayleigh quotient together with deflation techniques. Multi-Coloring is a simple technique to obatin the parallelism of order n, where n is the dimension of the matrix. Block SSOR is a symmetric preconditioner which is expected to minimize the interprocessor communication due to the blocking. We implemented the results on the CRAY-T3E with 128 nodes. The MPI(Message Passing Interface) library was adopted for the interprocessor communications. The test problems were drawn from the discretizations of partial differential equations by finite difference methods.

The field studies were carried out in paddy field over a four year period in order to find out the effects of butachlor, nitrofen, oxadiazon or CG 102, benthiocarb-S, and bentazon applied successively to the same paddy field for four years on weed succession and rice yields under different fertilized conditions including compost, chemical fertilizer and straw application. Total dry weight of weeds was steadily increased yearly over 4 year period regardless of fertilized conditions, and significantly higher increase of weed dry weight was observed on non-fertilized and compost plots. The most dominant weed species was Scirpus hotarui, and Potamogeton distinctus, Eleocharis kuroguwai and Cyperus serotinus were predominated on compost plot, E. kuroguwai and E. aclularis on non-fertilized plot, E. kuroguwai, C. serotinus, and Monochoria vaginalis on chemical fertifizer plot, and C. serotinus on straw plot. When the same herbicides were used continuously on the same plots, weed control effect was decreased and thus weed population was greatly increased particularly on butachlor and nitrofen treated plots. P. distinctus, E. kuroguwai, and C. serotinus were predominated on butachlor treated plot, P. distinctus and C. serotinus on nitrofen treated plot, C. serotinus on benthiocarb-S treated plot, C. serotinus and P. distinctus on oxadiazon or CG 102 treated plot and P. distinctus on bentazon treated plot. Annual weeds were slightly increased by repeated annual application of oxadiazon or CG 102 and benthiocarb-S, whereas perennial weeds were predominated by successive application of butachlor, nitrofen. and bentazon for 4 years. Yield reduction of rice became prominent by successive application of same herbicides. particularly butachlor and nitrafen. This results suggested that successive annual application of same herbicides should be limited and herbicide combination or herbicide rotation should be applied to control the remaining weed species.
