In a case of driving beginnners, it is very difficult to park a car perfectly because driver's knowledge makes more errors than intelligent mechanism when they are performed repeatedly. However skilled drivers be of experienced knowledge are able to park a car quickly. In this paper, we analyzed driving patterns of skilled drivers, designed the fuzzy controller to park based on it, and perform auto-parking simulation of a car using that controller.

In this study, the elevational distribution of breeding birds in Seoraksan National Park, Korea was investigated. Forty-six species of birds were documented from line transect surveys taken from Seorakdong at 230 m above sea level (a.s.l.) to the Daechungbong summit at 1708 m asl. Birdspecies richness and diversity were highest in Seorakdong and lowest at the Daechungbong summit. As elevation increased, bird species richness and diversity decreased, with a humped-shape trend being observed between 700 m and 1200 m a.s.l. Stepwise analyses revealed that breeding bird species diversity indices were significantly negatively correlated with elevation (r² = 0.327, P < 0.001) and positively correlated with vegetational coverage (r² = 0.324, P = 0.046). Higher elevations supported fewer birds than low and intermediate elevations. Projections at the local scale, including data on behavior and habitat use by birds, will be necessary for optimal conservation and management of the bird communities in Seoraksan National Park.

표준균주를 포함한 230여개의 김치유래 젖산균에 대한 균체지방산(FAMEs)을 분석하였다. FAMEs profiles는 Euclidian Distance 17.5에 의해 7개의 Major Cluster와 1개의 Single Cluster로 나뉘어졌다. 이중 A, B, C 및 Cluster는 Leuconostoc속으로 분석되어졌고, F는 Lactobacillus속으로 분석되어졌다. 그리고 E와 G cluster는 두개의 Genus가 혼재되어 나타났으며 보충적인 연구가 필요하다. 앞으로 김치유래 젖산균의 균체지방산 분석결과를 기반으로 한 데이타베이스에 95가지 탄소원을 이용하는 수치분류학적 접근방법 및 Pyrolysis Mass Spectrometry 등의 화학적 분석 방법과 분자친화적 연구를 통한 종합적 분류정보 체계가 갖추어지면 젖산균의 신속, 정확한 동정 및 연구에 활발히 이용되어질 것이다. Two hundreds and thirty lactic acid bacteria, mostly isolated from Kimchi, including type strains were sued for analysis of cellular fatty acids. The 230 test strains were recoverd in 7 major and 1 single clusters defined a Euclidian distance of 17.5. These aggregate taxa were equivalent to the genus Leuconostoc (aggregate group A, B, C and D), and the genera Leuconostoc and Lactobacillus (aggregate group G). It is concluded as evident that FAMEs (Fatty Acid Methyl Esters) profile of cell can be used as a criterion in classification of lactic acid bacterial from kimchi. Additional comparative taxonomic studies need to be carried out on well chosen representative strains to determine the most appropriate methods of value.

연안 양식어장의 정보 관리에 실용적인 지리정보시스템(GIS)을 적용함으로써 어업종사자와 연안 관리자에게 실현 가능한 관리방안을 제시하고 수산업 발전을 위한 유연한 의사결정의 기반을 마련하고자 하였다. 연안 양식어장의 효과적 관리는 경제적 실행 가능성과 운영비용에 영향을 미치며 양식 대상생물의 생산 및 사망률과도 관계가 있으므로 매우 중요하다. GIS는 양식어장 정보의 효율적인 관리도구로서 개인 및 공공분야에서 폭넓게 사용되고 있으며 해양수산 관련분야에서도 활발히 적용되고 있다 본 연구에서는 진해만을 대상으로 연안 양식장 자료의 3차원 가시화 모듈을 구축하였다. This paper illustrates some practical geographic information system (GIS) applications for aiding fishery managers and coastal area planners in analysing the likely control scheme of coastal farming areas, and in providing a flexible framework for decision making on fishery development and zoning issues. The effective management of marine farming operation is vitally important since it can greatly influence economic availability by determining capital outlay and by affecting running costs, rates of productions and mortality factors. GIS has been widely adopted elsewhere as a potent management tool in both the private and public sectors. GIS is now being extensively adopted in marine-associated activities. Here, we have used GeoMania v2. 5 GIS software and its 3D Analyst extension module to visualize marine farming areas data that were collected around the Jinhae bay.

肝臟疾患에 있어서 血淸鐵値 變動에 關한 臨床的 硏究

朴贊鍾,高侊道 고려대학교 의과대학 1972 고려대 의대 잡지 Vol.9 No.1

On the patients of liver diseases who had been admitted to the Gastroenterology of this hospital, the serum iron levels was determined in 221 patients from whom they were subdivided into 88 cases of infectious hepatitis (48 cases of acute hepatitis and 40 cases of chronic hepatitis), 99 cases of postnecrotic liver cirrhosis, and 34 cases of primary hepatoma. The relationships between the serum iron level and the liver function tests, such as A/G ratio, total bilirubin, alkaline phosphatase activities, transaminase activities, total cholesterol levels with its ester form(%) and thymol turbidity tests according to the kinds of liver diseases were observed. The results were as following. 1. Of liver diseases, in cases of the primary hepatomas, the serum iron levels was remarkably decreased to 84.0 rg./dl. compared with the normal value 136.9 rg./dl. and postnecrotic liver cirrhosis showed the values 144.0 rg./dl. closely resembled to normal values. Infectious hepatitis showed the more increase of iron level than normal. Namely, acute case was 158.7 rg./dl. and chronic case was 186.0 rg./dl. 2. In the primary hepatomas, in addition to the remarkable decrease of serum iron level, reversed A/G ratio, the increases of total bilirubin, alkaline phosphatase activities and transaminase activities, increase of total cholesterol with its ester form(%) decreased and the increase of thymol turbidity tests were also noted. 3. However, is the acute infectious hepatitis, another with the primary hepatomas, the tendency of increases of alkaline phosphatase activities, transaminase activities, total cholesterol and thymol turbidity tests were observed as well as the increase of serum iron level. 4. And the correlations between the significant abnormal findings of liver function tests and the serum iron levels were not noticed in cases of liver cirrhosis and the chronic infectious hepatitis. 5. Such relations suggest the abnormal findings of liver function tests do not keep pace with the variety of serum iron level but occurs differently according to the lesions of liver diseases themselves. And that serum iron level might be helpful for the differential diagnosis between primary hepatoma and other liver diseases.

The results of individual PAH source profiles that can be applied to receptor model are as follows. The sum of 16 PAH concentrations was 391.41 ng/S㎥ in a tunnel. Phenanthrene was the most abundant compound among 16 PAH, and then pyrene, fIuoranthene, anthracene, and naphthalene can be seen in elevated contents. 11,056.61 ng/S㎥ of 16 PAH concentrations in BC oil boiler was two times higher than 6,582.57 ng/S㎥ of those in LNG boiler. Naphthalene was the most abundant compound in both facilities. Phenanthrene, anthracene. and acenaphthylene were the second dominant compound group in order from both facilities. BC oil boiler had relatively high concentration of pyrene compared to LNG boiler that had high concentration of fluorene and did not detect pyrene. The sum of 16 PAH concentrations emitted from MSW incinerators after APCD (air pollution control device) was three times higher than those from MSW incinerators bcfore APCD. However, the concentrations of more than 4-ring PAH compounds (e.g., benzo (a)anthracene) before APCD were higher than those after APCD. This fact implies that PAHs generated by combustion process are eliminated in APCD and they are continuously produced in stack or atmosphere by PAHs precursors.

Genetic loci that contain a variable number of tandem repeats(VNTR) could be successfully amplified from a very small amount of genomic DNA by the polymerase chain reaction(PCR) and have been applied to individual identification in forensic field. Forensic samples are sometimes not a sample of one individual, but mixed sample, such as blood, hairs, and vaginal fluid with sperm. Even though very small amount of sample is mixed to the large one, the small fraction of the mixture is amplified by PCR. But sometimes it could not be detected in electrophoresed agarose gel with ethidium bromide staining, because the PCR products of small fraction are less amount rather than that of large fraction of mixed sample and because of the limitation of the sensitivity of ethidium bromide staining in agarose gel. We investigated to search the detectable limitation of the PCR products of mixed sample with various ration, experimentally. The sample were mixed with various ratio, amplified by polymerase chain reaction, electrophoresed, and stained with ethidium bromide. We can detect the small fraction of mixed sample from the 50% to the 5.9% or 3.0% of blood mixture and to the 0.8% of DNA mixture. In Southern blot, we can detect the small fraction in all ratio of blood mixture, to the 0.26% which is the smallest ratio of mixture in this experiment. Form the results, in samples which have a possibility of mixed sample, the southern blot analysis is necessary to increase the sensitivity of DNA fingerprint.

농업기술혁신의 경제성 평가와 관리체계

This study originated from an issue that technological innovation is an important factor in modern agriculture and it should be controlled systematically by government and farms. The objective of this study is to find out the methods of economic evaluation and management system of technological innovation in agriculture. Technological progress in agriculture improves the agricultural production function. For any given amount of inputs, we get more output than we did in the past farming. Modern theories of endogenous growth attempt to explain the rate of technological progress, which the Solow model takes as exogenous. These models try to explain the decisions that determine the creation of knowledge through research and development. The growth of agricultural income per farm is determined by the rate of technological progress. Because technological innovation in modernized agriculture is very important factors increasing the revenue and reducing the production cost. The difference between production functions is due to a difference of technique in how the inputs are used in producing the output. A farmer will not adapt a change in technology unless he expects that the adaption will lead to a reduction in per unit costs at the output at which he expects to operate. Since most innovations involve additional expenditures, total costs are likely to be increased at lower levels of output as a result of technological changes. Nevertheless, in order to increase the agricultural production and the levels of living it is necessary to develope and adapt technological improvements in agriculture. The major problem in agricultural technological innovation is to evaluate the economic value of new technology adapted by farmers in agricultural accounting system and to prepare the technological management system to develope better technology. Farms should reflect the economic value of technological changes through financial analysis in agricultural accounting system. Because an essential activity in financial management of agriculture is the development of a timely technological information system that provides a means for the decision maker as a farm operator to measure, evaluate, control, and improve the financial performance of the farm business. The government should develope the education of the skilled technical hands, R&D investment, the accumulation and risk management of agricultural technological information, and the development and spread of agricultural technology. We can expect the principal role of local agricultural college in technological management system of agriculture by the decentralization of agricultural extension function.
