Currently, digital maps in the metropolitan area are supposed to be revised and renewed every two years, but it is difficulty for the renewal of current information to keep pace with the quickly changing society and so, one of the alternative methods being discussed is a digital map produced using high resolution satellites. The biggest problem in the production of digital maps using high resolution satellite images is the difficulty of production in vector resource format through edge detection of satellite images, a Raster data. In this study, topographical boundaries were detected through edge detection of the satellite image, and after vectorliezing using the screen digitizing method, the results were evaluated and compared to the digital map from the NGII(National Geographic Information Institute) for accuracy.

국내 발전소별 바텀애시를 잔골재 대체재로 사용한 모르터의 특성에 대한 실험적 연구

송민섭,장재봉,조봉석,김재환,김용로,김무한 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.1(구조계)

With the advance in industrial development and modern living comfort, the demand for electricity throughout the country is ever increasing. Also the annual consumption of coal by coal-fired power plants is increasing. The amount of ash produced in 2000 is estimated to be about 4.5 million tons. The disposal of this huge amount of ash introduces serious environmental problems. Fly ash among the ash produced is used in building industries as a substitute to cement in concrete and the concrete thus produced is said to be lighter and stronger. But bottom ash among the ash produced is not used because of its poor properties. But encouraging the use of bottom ash as a construction material is a sensible method of utilization as it avoids the problems and costs associated with disposal and provides an alternative aggregate source. This study is aimed at using bottom ash as an alternative fine aggregate source to provide a solution to disposal and insufficient fine aggregate for the production of concrete. So properties of bottom ash produced in power plants were estimated due to the difference of bottom ash produced in each plant. And mortar strength was estimated as basic data to use bottom ash in building industries.

This study was conducted in order to analyze freshmen's level of cognitive judgment of moral situations and their conceptions of moral situation in different conceptual domains. The research questions to be answered in this study were as follows : 1) What are freshmen's levels of the judgment in moral situations, and are the levels differentiated according to their sex and majors? 2) What are the justifications in each domain? In other words, how do justifications of nonpermissibility, generality, and rule-independency differ in such domains as moral, conventional, and personal? 3) How are freshmen's conceptions of moral situation characterized? Subjects in this study were 200 freshmen(131 boys and 79 girls) randomly sampled from Dong-a University. The instruments were Kim's(1985) Test of Moral Development Judgment which was translated from Rest's(1979) DIT, and 9 interview situations for moral judgment and justfication developed by the current researchers on the basis of Turiel's theory. Subjeects were presented with six moral dilemas and 9 moral situations by 10 research aides who are seniors of education department of dong-A University, specially trained for this study. Data were analyzed statistically to answer the research questions. The major findings of this study were as follows: 1) More freshmen attained level P in terms of judgment of moral situations, while some other students did levels three and four. Therfore, it is considered that a large amount of freshmen start the principled-stage thinking. 2) Many freshmen showed high degree of transitional phase(4½) as level P according to frequencies in each moral stage. This reflects the apparent regression from the hightest stages to stage 2 during freshmen's campus life. Additionally, this kind of regression is found in arts and physical education students rather than other students. 3) There is no sex difference in the levels of freshmen's moral judgment. 4) Freshmen justified the transgressions in moral situations on permissibility and generality. Therefore, they appear to view moral issues as more legitimately subject to moral domain. In part, they tend to view moral issues as subject to conventional domain in that they justify the affairs related to peers of elders on rule-dependence. 5) Freshmen's domain distinction was apparent in that they justified conventional issues on generality. However, they are also seem to moralize since they partly view conventional issues containing relationships with parents as subject to moral domain. 6) Freshmen justified personal issues on rule-dependence and generality. Therfore, it is concluded that they justify the personal issues as subject to conventional domain. 7) Freshmen are more likely to reason about moral issues as personal obligation and sort them as under moral domain. However, within-domain differences in justifications are apparent in that freshmen treated the moral issues as subject to customs or traditions, or personal choice. 8) A strong moralizing is evident in that freshmen conceived conventional issues in terms of other's welfare rather than conventional reason. 9) The within-domain consistence is obvious in that freshment reasoned about personal issues as personal and sort them as under personal domain. However, it is found freshmen's moral conceptions are dependent on situations because some students justified personal issues on other's welfare or obligation while other sutdents did on moral reasons and conventional sanctions or customs.

송은섭,황적준,남용석,한길로 大韓法醫學會 1997 대한법의학회지 Vol.21 No.1

The four tetrameric STRs loci(MUMvWA31, HUMTHO1, HUMF13A1, HUMFES/FPS) were studied to confirm the allele frequency distribution and to see whether these results can be used for identity and paternity testing in a population of Koreans using multiplex PCR and laser-fluorescence detection method. In the Korean population (n=227), 8 alleles with their relative frequency range of 0.002-0.249 are detected in the HUMvWA31 locus, 6 alleles with those of 0.007-0.500 in the HUMTHO1 locus, 6 alleles with those of 0.002-0.487 in the HUMF13A1 locus, and 6 alleles with those of 0.004-0.434 in the HUMFES/FPS locus. The highest observed heterozygosity is found at the locus HUMvWA31(0.8077), with those of the loci HUMTHO1, Humf13A1, and HUMFES/FPS being 0.6581 0.6324 and 0.6804, respectively. All loci meet Hardy-Weinberg expectations: there are good agreements between observed and expected heterozygosity, number of observed genotypes. Pairwise comparisons between loci show allelic independence for all the 4 loci. The power of discrimination (PD) determined for the locus HUMvWA31 is 0.933, that for the HUMTHO1 is 0.836, 0.798 for HUMF13A1, and 0.844 for the HUMFES/FPS; the combined power of discrimination for the quadruplex is 0.9997. Thus, these allelic frequency distribution can be used to construct the database of the multiplex PCR-based DNA profile in the Korean population. The calculated parameter, "combined power of discrimination(PD)" show the informativeness of these loci for the determination of identity and relatedness of individuals.

A neurilemmoma is a relatively uncommon tumor of the nerve sheath and almost never in malignant form. It is a slow-growing, encapsulated nerve tumor. Benign neurilemmoma occur commonly in the cranial acoustic nerves, but can occur on the flexor surfaces of the upper and lower limbs. There is no appreciable sex predilection, and most cases are seen in adults past the age of 30 years. The tumor has been seen to arise in major nerves and nerve branches, including the posterior tibial nerve, peroneal nerve, and femoral nerve. Common differential diagnoses are ganglion, lipoma, neuroma, and hemangioma. Symptoms most often are a palpable mass, usually tender to palpatioin. A history of a localized area of swelling that increases in size and firmness over a period of several years is usual. Hitsologically, the tumor is composed of antoni type A and B tissue. In Antoni type A tissue, there are interlacing bundles of spindle-shaped cells arranged in a compact fashion with a pallisading of cell uunuclei. Antoni type B tissue exhibits the same type of cells loosely arranged with intervening collagen fibers. The tumor usually is located in deep tissue and rarely is just under the epidermis. And so we represents 3 cases of intradermal neurilemmoma in our department of dermatology.
