This study looks into the differences between the two different genres of dramatic renditions on film- television dramas and movies, by studying the respective characteristics of screenplays for television and movies, and comparing the disparity in status between the powerful television drama writer and the powerless movie screenwriters as well as actual power structures within the Korean media industry. It explores the intensifying problems of high cost drama productions and poor treatment of screenwriters, as well as established practices in the movie and television industries so as to analyze problems comprehensively and seek balanced growth within these industries. The Hollywood screenwriting system is taken as a point of comparison in seeking solutions and exploring the direction that Korean film and television industries should take in the future.

The authors surveyed the cassettes in 10 general hospitals and compared in experimentation on performances of 6 kinds of cassettes manufactured with several materials in order to discover the present condition and performance of the cassettes being used at present. And the authors got the following results. 1. In distribution of the cassettes in use, Okamoto's(Japan), Picker's and Titan's(U.S.A.) were more than others classified by the manufacture. The rate of using high speed was 72.0%, par speed 28.0% classified by types of intensifying screens in the cassettes and the rate of the year in use for $4{\sim}5$ years was 40.0%, $6{\sim}7$ years 24.0% classified by the years in use. 2. The results of the screen-film contact test were that tile ordinary was 42.7%, the good 36.0%, and the poor 21.3%. 3. The results of the test for light leakage were that fogged area appeared on 1 side or more in 84.0% films. 4. In Aluminum equivalents of front plate, the cassettes with a front plate consisting of carbon fiber were fewest, and the ones of bakelite and aluminum were fewer in order 5. In compared results of the exposure dosage for same density of the films, the exposure of the cassettes used carbon fiber for the material on the front plate was smallest and bakelite, auminum was smaller in order.

The arbitrary primer polymerase chain reaction(AP-PCR) and Southern blot restriction fragment length polymorphism(RFLP) were used to genotype the cariogenic pathogen S. mutans in children. Following the morphologic chracteristics of colony on selective medium for S. mutans, total genomic DNA from 155 strains was extracted by conventional methods. Among 155 strains, 143 strains (92.3%) were confirmed S. mutans by PCR with dexA gene and 114 strains were used in this study. Three random sequence 10-base oligonucleotide primers were chosen for AP-PCR. The amplified DNA products were separated electrophoretically in a 2% agarose gel containing ethidium bromide and the banding patterns were compared among different strains. For RFLP analysis, DNA was digested with EcoRI and BamHI, separated on a 0.7 % agarose gel and transferred to a nylon membrane. The membrane was probed with a previously characterised 1.6 kilobases (kb) DNA fragment cloned from gtf B gene of S. mutans. The probe was labeled with isotope[$^{32}P-{\alpha}CTP$], and hybridized fragments were detected with intensifying screen. AP-PCR produced 4-8 DNA bands in the 0.25-10 kb regions and distinguished 9, 10 or 12 genotypes, depending on the specific primer used. Southern blot RFLP analysis revealed 2 hybridization patterns consisting of 1 DNA fragments 450, 500 bp. These results indicate that AP-PCR is more discriminative method for genotyping of S. mutans.

In the industrial field for product inspection needs not only on the surface of the product but also the internal components defect inspection. Generally, optical inspection is mainly used for item inspection from production process. However, this is only to check defect of surface it is difficult to perform inspection of goods internal. To overcome these limitations, Instead of optical device by using the portable X- ray DR image acquisition device system developed to obtain an image in real time at the same time and determine product defects. After obtaining the X- ray image, the inspection product within error range is passed after machine image processing. Also, the results and numbers are stored by users.

Purpose : To valuate the usefulness of mammographic image by using phantom 1,2 to controls the enhancement of image quality. Procedure : Set up same equipments for experiment (all the qualification must be the same). Control group and 4 other experiment the developing mammographys by using the image system with film/intensifying screen and distribute marks on each test objects of phantom 1, 2. Result : The results of the experiment using phantom 1, 2 on control group and 4 others are : 1. phantom 1's valuation with 3 items. - control group received 29 out of 32 - group A received 25 - group B received 16 - group C received 11.5 - group D received 28.5 The evaluation shows that the system has proved to display excellent image quality except group B and C. 2. Phantom 2's valuation with 4 items. - control group received 38 out of 38 - group A received 30 - group B received 16 - group C received 12.5 - group D received 38 Even with phantom 2, group B and C has displayed poor image quality. Conclusion : Both experiments using phantom 1 and 2 have shown that the most strong factor that control and influence the image quality are the filming equipments. Especially, the developing system has most powerful influence above all.
