The monobath method is accomplished using chemical solution, as processing in a developing and fixing at the same time, into which the exposed photographic material is placed. For this study, we appointed some values to be a standard that to coming as a results by normal processing with the developer D-76 for film Fuji Neopan SS 35mm, and which is compared with a monobath process. The experimental results show that processed condition is useful and applicable in monobath, for FX-6a and Keelan No.315.

The main purmose of this study is to establish the corelatione between the ink receptivity and the surface 초\ulcorner岺\ulcornerparamenters in the presence of the dampening solution in the Lithographic Printing. The surface chemical parametere are calculated from the components (dispersion part and polar part) of which the surface tension of various surfaces acd ink are estimated from the contact angle The conclusions are; 1) the receptivity of ink depends on the value of polar part of surface tension, ; and ink, ;and decreases as the value of and increase, 2) the adherence of ink depends on the value of ink and dampening solution, and decreases as the value of dampening solution, decreases on the image area.

The anodixed aluminium film by sulfuric acid - method has many pores, the inner, called barrier layers, is active. They have strong absorption of dye. on be other, the absorption of dye is lost by Sealing, the surface is not dyed. We make IMAGE FORMATION on the film by the chemical behavior. This study made sure whether ion absorption is not in the barrier layer by IRRS and ESCA, considerated the mechanism of inage formation.

For the development of colored-proto grapby, the silver dye blech processes were extensively studied. For the first time, the developed silver was main catalyst, but recently active organic compounds are widely used as organic catalyst. They were guinoxaline and phenazine derivatives and it may forrned protonated free radical(${AH_2}^+$) under the presence of strong acid. Herewith the chemical reaction involved those catalyst and it's kinetic theory were described. Also, properties of the product with organic catalyst and improved process was reviewed.

In last few decades, medical imaging techniques have been developed startling progress. Especially in MRI (Magnetic Resonance Imaging), many imaging techniques such as chemical shift imaging, flow imaging, diffusion and perfusion imaging, fast imaging, susceptibility imaging and functional imaging have been studied and many of them were well known as useful diagnostic instruments. In this paper, recently developing techniques, i.e., NMR microscopy, fringe field imaging and functional imaging will be presented.

This paper deals with the network interface of research and observation instruments in the oceanographic research vessel with an establishment of related database for measured information. The system is implemented to integrated communication network system which allows to effective survey by using real time observation and GUI(Graphic User Interface). The system also consists of the LAN systems and serial interface to link chemical, physical, biological and environmental relations. And, other network service and vessel data service for data communication between vessel and earth station such as INMARSAT-B, WWW service, BBS, E-Mail etc., are needed for integrated communication network system.

The present communication deals with development of ten novel N-Phenyl-3-Pyridin-2-yl imino derivatives as vascular smooth muscle relaxants. The derivatives were prepared and optimized using pocket modelling and pharmacophore modelling. The 4 hydroxy substituted derivatives are showed potent activity comparable to the sildenafil.

The trans-$A_2B_2$ porphyrin and Ni-porphyrin derivatives were synthesized by Suzuki coupling of bromoporphyrin with arylborate as a key step. The band gaps of those complexes were measured from their absorption, emission and cyclic voltammetric data. All the LUMO energy level of porphyrin derivatives is lower than that of P3HT, and the HOMO energy level is evaluated higher than the HOMO of PCBM.

Substituted butadiyne cobalt complexes 1, 2 were prepared and placed on the e-beam to study the fragmentation focused on diyne generation, in MS spectrometer. Phenyl or methyl substituted cobalt complexes generated the corresponding diyne with 100, 30% relative intensities under e-beam irradiation in gas phase.
