Soybean yellow common mosaic virus (SYCMV) has been recently reported, it has been occurred a lot with Soybean mosaic virus (SMV) and Soybean yellow mottle mosaic virus (SYMMV) in soybean field. SYCMV belongs to genus of Sobemovirus and induced viral symptoms with yellowing, mottle and mosaic. A reverse transcription loop-mediated isothermal amplification (RT-LAMP) method allowed one-step detection of gene amplification by simple procedure and needed only a simple incubator for isothermal template. This RT-LAMP method allowed direct detection of RNA from virus-infected plants without thermal cycling and gel electrophoresis. In this study, we designed RT-LAMP primers named SYCML-F3/B3/FIP/BIP from coat protein gene sequence of SYCMV. After the reaction of RTLAMP, products were identified by electrophoresis and with the detective fluorescent dye, SYBR Green I. under daylight and UV light. Optimal reaction condition was at 63 for 60min and the primers of RTLAMP showed the specificity for only SYCMV tested in this study.

Youngdo Island is suitable to be developed as a tourist town due to its beautiful natural surroundings. In connection with the above purpose, various harmful heavy metals were analyzed to investigate the level of pollution of Youngdo soil. The elements tested were Cd, As, Sn, Cr, Cu, Pb, Co, Ni, Mn and Zn. The results from Youngdo were compared with those of the Busan and the whole country in the investigation items which were decided by the Korean Ministry of Environment. The average contents of heavy metals in Youngdo soil were comparatively lower than those of Busan, and close to those of the whole country including uncontaminated natural soil. It was found that Youngdo-Gu remains clean soil environment except a few investigated sites at the industrial areas even though this district belongs to the Metropolitan Busan. This fact implies that Youngdo is to get well ready for a tourist town.

김대환,최연성,고남영 群山大學校 1996 論文集 Vol.23 No.-

Parsing video content is an important first step in the video indexing process. This paper presents algorithms to automate the video parsing task and the presentation key-frame extraction. In this study, we propose a cut detection algorithm using linear coefficients of correlation from edge-map and analyze the existing cut detection methods. Experiments applying to real video clips confirm our methods. Video data modify it for dissolve effect which is fade-out and fade-in. Finally we design a browsing system for video data that use our cut detection algorithm.

釜山의 工業空間에 關한 硏究 : 工業空間의 分布와 그 要因 分析을 中心으로 the Distribution of Industrial Spaces and the Analysis of Its Factors

林永大 新羅大學校 1977 論文集 Vol.5 No.-

In this study, an attempt is made to clarify the locational pattern of the Korean industry and that of all industries by analysing the spatial variation and its main factors of the industry in Busan. The numbers of plant and employee by category and by dong in Busan shi(sity) were used as the basic data for this study. Spatial variation of industries were examined through mapping the relative intensity of industries and simplifying them into the models. To find the factors influencing spatial variation of industries, correlation analysis between eight expected independent variables and intensity of industries was attempted. The results are as follows; While industry in Busan has the same characteristics of medium and small industries as that of the Korea, it shows much heavier concentration of industrial acitvities than any other region and depends largely on the heavy & chemical industries. Although there are differences of size and pattern among the categories of industry, industrial spaces in Busan form their axes of distribution running to the direction of northeast-southwest. As in the case of other city, distribution of industrial space is the result of such spatial variations that change in turn the unit space into the core industrial space, industrial space, quasi-industrial space and non-industrial space as one crosses from their cores to urban fringe; the core(s) of heavy industry lie(s) on the coast in contrast with the cores of light and chemical industries lying on the interior. That is, these industrial spaces can be categorized into two types of industrial spaces in terms of the number of core. They are; 1. Industrial Space of Single Core ; a. chemicals, petroleum, coal rubber, plastic produces, b. wood, wood products including furniture. 2. Industrial Space of Multiple Cores ; a. Busan, b. food, beverage, tobacco, c. textile, wearing apparel, leather, d. paper, paper products, printing, publishing, e. non-metallic mineral products, f. basic metal, g. fabricated metal products, machinery, equipments. Also we can categorized them into three types in terms of the position of core. They are; 1. Industrial Space of Coastal Core(s) ; a. wood, wood products including furniture, b. basic metal. 2. Industrial Space of Coastal Core(s) ; a. Busan, b. food, beverage, tobacco, c. textile, wearing apparel, leather, d. paper, paper products, printing, publishing, e. chemicals, petroleum coal, rubber, plastic products, f. non-metallic mineral products. 3. Industrial Space of Coastal % Interior Cores ; fabricated metal products, machinery, equipments. And there are seven important industrial regions in Busan as the result of spatial variations They are; 1. Central Eastern (Beomil & Yeonsan)Industrial Region. 2. Central Western (Sasang) Industrial Region. 3. Northern(Dongrae) Industrial Region. 4. Southwestern(Gamcheon) Industrial Region. 5. Southeastern(Yeongdo) Industrial Region. 6. Chungmu Industrial Region. 7. Gupo Industrial Region. Most of these industrial regions depend heavily on the textile, chemical and machinery industries of medium and small size. But it is noteworthy here that most of these industrial regions locate in the heart of city, especially the Central Eastern Industrial Region being the largest of these seven industrial regions abuts on sub-C. B. D. of Busan, which are harmful to the development of the city and industry. On the other hand, eight expected factors selected in this study explain only about one third of spatial variation of industry in Busan though the influences of such factors as distance from habour and station, road and labour on the spatial variation are important. And it is certain that the remainders of spatial variation can be explained by such factors as public policy, historical accident & inertia, personal preference and agglomeration which are neglected in the selection of expected factors in this study. Therefore, for a fuller explanation of the spatial variation of industry in Busan, such approach that not only take into consideration of eight expected factors but also emphasize the factors as public policy, historical accident & inertia, personal preference and agglomeration is necessary. Can't these be adopted in the study of the spatial variation of industry not only in Busan but in all of the Korea? Or in the study of all spatial variation of industries? A more advanced study is required in this field.

都市工業의 成長과 構造變化 : 馬山市의 경우 the Case of Masan City

林永大 新羅大學校 1989 論文集 Vol.28 No.-

The main purpose of this study is to clarify characteristics of manuacturing gorwth and its structural changes in the study area, and to verify whether the existing theoretical and empirical studies on the growth and structural changes of urban manufaturing are applicable to the case of study area. The scondary purpose is to find problems in its manufacturing growth and structural changes, and to search for effective devicefor solving the problems. Masan city was selected as the study area, and manufacturing growth and structural changes between 1876 and 1986 were examined. Hard data were used as the basic data. They were about the number of establishments and employees by type and size of manufacturing recorded in yearbooks and registers of firms. The major findings were as follows: 1. Manufacturing in the study area had been initiated mainly by Japanese in the study area had been initiated mainly by japanese capitals and technology since Russo-Japanese War. and there already was heavy manufacturing agglomeration in the study area in the period of Japanese rule. 2. In spite of rise and falls in the manufacturing growth of the study area. the speed and degree of manufacturing agglomeration tend to be decreased relatively. 3. Manufacturing growth of the study area was acompanied with structural changes of manufacturing: the manufacturing structure tneds to be diversified and, the change of the prominent components in the structure tend to be from such manufacturing as Foods Products. Beverages, Printing & Publishing. Wood & Cork Products, Fabrica?ed Metal Products, to such manufaturing as Textile, Fabricated Metal products, Electrical Machinery. And also the changes of the kinds of specialized manufacturing tend to be from such manfacturing as Foods Products. Foods Product, n.e.c, Beverages, Printing & Publishing to such manufacturing as Textile. Fabricated Metal Products, Electrical Machinery. As the results, such manufacturing as Textile, Fabricated Metal Products and Electrical Machinery tend to growth and to be specialized with contrast to the decrease of such manufacturing as Foods Products, Food Products, n.e.c., Beverages, Printing & Publishing and Wood & Cork Products. 4. Firm size of manutacturing in the study area tends to be enlarged, but small firms are still prominent. 5. Characteristics shown in manufacturing growth and structural change in the study area which are tendency of structural diversification, enlargement of firm size, and prominence of small firms, are the same as those of Korean manufacturing. Differences between manufactruing in the study area and Korean manufacturing are growth speed, firm size and the kinds of the prominent components in the sturcture. 6. Th growth and structual changes of manufacturing in the study area resulted mainly from national policies and geographical conditions of the study area as habour. To extract the facts relavant to the hyphtheses established in this study among the described above, they are as follows: 1. The speed and degree of manufacturing agglomeration in the study area tend to decrease.(hypothesis 1) 2. Manufacturing structure in the study tends to be diversified with the manufacturing growth, and to change the prominent components, which ?s from low value added, pre?stage manufacturing to high value added, post-stage manufacturing. (hypothesis 2) 3. The firm size in the study area tends to be enlarged.(hypothesis 3) 4. The growth and strutural changes of manufacturing resulted mainly from national policies and geographical conditions of the study area as hobour.(hypothesis 4) To verify the hypotheses established in this study on the basis of the above four facts proved that all of four hypotheses were verified positively. In conclusion, it would be possible to explain the manufacturing growth and structural changes in the study area by preceding studies, since manufacturing growth and structral changes in the study area are not so different from the cases in foreign countries. On the basis of the above facts, I found the problems in manufacturing growth and structral changes in the study area. 1. The degree of manufacturing agglomeration in the study area tends to decrease as the speed of its manufacturing growth decrease. 2. In spite of structural changes from low value added pre?stage manufacturing to high value added post-stage manufacturing. one(Textile) of five prominent manufacturing(Textile, Fabricated Metal Products, Electrical Machinery, Transport Equipment, Professional Equipment) in the structure, is the manufaturing of tends to decrease with manufacturing development. And this textile manufacturing, with manufacturing of electrical machinery, has great influences on the economy of the study area. Therefore, industrial policies inducing existing manufacturing agglomerated in the study area to the high-value-added post-stage manufacturing is necessary for solving the above problems: four prominent manufacturing of high-value-added and post-stage described above should be promoted and should be export-orienting, while textile manufactruring should be controled.

This study was carried out to determine the promising method for the production of mother bulbs using garlic bulbil at the experimental field of Ange high school, Eusung in Korea from 1996 to 1998. The bulbs and bulbils were taken from a local cultivar 'Eusung' garlic. The growth of bulbil and yield potential were compared with different harvesting times and cultivation methods of bulbil. The harvesting time of bulbils which were capable of producing the mother bulbs was ranged from 15 days to 30 days after the emergence of flower stalks. The best results based on the yield and number of bulbs were obtained from the bulbils sampled at the just before garlic harvesting, 30 days after flower-stalk emergence. The mulching with transparent polyethylene(PE) film in bulbil cultivation was more effective for the plant growth and bulb formation than that with black PE film. The PE mulching from 30 days after seeding of bulbils to 30 days (late-April) before bulb harvesting was the most effective for the increase of bulb yield. In the cultivation of garlic bulbils, application of lime (150kg/10a) and compost (3,000 kg/10a) without any chemical fertilizers produced more bulbs in comparison with the standard level of fertilizer (N - P2O5 - K2O - compost -lime = 24.8 - 8.0 - 19.2 -3,000 - 150 kg/10a). It was determined that the involucre seeding and assemble seeding of bulbils was effective and labour-saving methods for the production of mother bulbs from garlic bulbils. Input of labour force for the involucre seeding was decreased up to 61% as compared with the conventional drill seeding of bulbils. Mean yield from the cultivation of bulbil-derived single cloves was remarkably increased up to 95% in comparison with that of the common cloves. The larger size of single clove produced more yields, and the optimum planting density of single clove was 20×10cm. The cloves differentiated directly from bulbil showed to have higher yield potential than that from common cloves.

馬山工業의 立地變動

林永大 新羅大學校 1991 論文集 Vol.32 No.1

The main purpose of this study is to clarify the characteristics of location and locational change of manufacturing firms in Masan city, and to examine whether the results of preceding studies on the manufacturing location in the other urban areas are applicable to the manufacturing location in Masan city. Basic data in this study were collected from interviews with owners of manufacturing firms located in Masan city. The interviews have been planned to be done to the owners of 159 firms selected by Stratified-Optimum Allocation Sampling Method, and the were actually done to the owners of 134 firmsamong them. The major results of this study were as follows : (1) The investment decision of each firm mainly depends on the prospect and interest of business and existence of potential entrepreneurs employed in the related industries. (2) The locational decision is divided into regional selection and site selection. In regional selection territorial relationship, agglomeration, government policy and contacts with purchasers are important. However, territorial relationship in regional selection and land in site selection are the most important factors in respective. (3) Responding to the environmental changes of firms breaking locational equilibrium, most firms adjust locationally and take new locational equilibrium. Two types of locational adjustments are found : One is investment change and the other is relocation of firms. Investment change is more frequent than the relocation, and results mainly from market fluctuation. The relocation of firms resulted mainly from expansion and modernization of existing product lines, and diversification into new product lines. The necessity of close contacts with purchasers and related activities limits the spatial extent of relocation of firms within short distance. Examining five hypotheses established in this study on the basis of above facts, all of hypotheses were examined positively, but three hypotheses)(hypothesis 1, 2and 4) patially. Therefore, it would be possible to explain the manufacturing location in Masan city by the results of preceding studies on the manufacturing location in the other urban areas, since the locational characteristics of manufacturing in Masan city are not so different from the cases of the other cities.

釜山工業의 空間變化(1962-1976年)

林永大 新羅大學校 1979 論文集 Vol.7 No.-

This study puts the main purpose to clarify the problem whether or not the development of doughunt formations and differences of spatial variation between small and large firms are present in the spatial variation fo Busan i dustry. The data on number of establishment and employee by scale and dong in Busan city for 1962 and 1976 were used for the examination of spatial variation of Busan industry. Also, for the examination of processes of spatial variation, the number of stayer, mover and new firm in 1962 to 1976 was used as the dat. The results are as follows: The spaces of Busan industry in 1962 were localized in the city core area. but industrial spaces made the development into the urban friges, especially into the northern and northeastern parts in contrast to the decrease in city core in 1962-1976, through such main processes as death and birth of firms. Thus, its industrial spaces in 1976 were greatly expanded into the urban fringes, especially into the northern and northeastern parts. And the decrease of industrial intensity around industrial cores, the formation of belts commecting these cores, the locational differences between large and small firms appear on these spaces. Various characters in the spatial variation and it's processes of Busan industry are same as that of other cities. But it is noticeable that(1) its industrial spaces on the locational axis running to the direction of southwest-northeast developed into the northern and northeastern urban fringes, as the result of its geographical conditions, and (2) the main processes of its spatial variation are death and birth of firms. On the other hand, there five rings in Busan originated from the characters of spatial variation of industry and its provesses. They are" (1) city core; a few small firms and prominent decrease processes. (2) inner part of area surrounding city core; very few small firms and prominent decrease processes. (3) outer part of area surrounding city core; very few small firms and prominent decrease processes. (4) urban fringe; a lot of large firms and prominent increase provesses. (5) suburb; no firm and no process. As the result, the distributional shape(profile) of industrial spaces and intenstities in Busan are similar to the 'W' shape. However, as the provesses is continuing, that shape may eventually transform into the shape of doughnat ring

釜山의 工業空間에 關한 硏究(Ⅰ) : the distribution of Industrial Spaces in 1962 1962年의 工業空間의 分布를 中心으로

林永大 新羅大學校 1978 論文集 Vol.6 No.-

In this study, an attempt is made to clarify a part of locational patterns in 1062. I started with the assumption that there would be some categories in the distribution of industry in Busan city. The number of plant and employee by category and by dong in Busan city in 1962 was used as the basic data for this study. Distribution of industries was examined through the method of Principal-components Analysis and simplified into models. The results are as follows: There exist six categories in the distributions of industry in Busan city, but it is only a few cases that show same distributional type as the result of locational Characters (Fig. 2-7). Industrial spaces in Busan city form their axes of distribution running to the direction of northeast-southwest, although there are differences of size and pattern among the categories of industry. It is the same features as other cities in that most industrial spaces have their cores in the center and as one crosses those cores outward, intensity of industrial concentration decreases, and that in the developmental process of industrial space non-industrial space change in turn into the quasi-industrial space, industrial space core industrial space and industrial belt through the concentration of industries and expansion of industrial space (Fig.8). And in 1962, there were four important industrial regions in Busan city as the result of distribution of industrial spaces (Fig. 9). They are: 1. Geojae Industrial Region being predominant in the chemical industry. 2. Seomyen Industrial Region being predominant in the textile, rubber and wearing apparel industry. 3. Beomil Industrial Region being predominant in the lumber-wood products and rubber industry. 4. Yeongdo Industrial Region being predominant in the basic metal, stones-glasses(including clay and concrete)and transportation equipment.

Asbestosis is the disease of pulmonary fibrosis caused by the inhaled asbestos fibers, and could be diagnosed clinically, in the case of exposure history to asbestos is proved, by clinical symptoms of dyspnea or dry cough, physical examonation findings, and the radiographic features. But many othder inorganic dusts would show similar findings in the chest radiogram and sometimes the exposure history is obscure, so for the exact diagnosis of asbestosis lung biopsy is needed. In Korea, there have been some reports of survey in the workplace where asbestos is handled or of asbestos related diseases. This is a case report of asbestosis with accompanying pleural plaques, who had the occupational exposure to asbestos for 30 years and the consistent clinical, radiographic and pathological findings in the lung tissue obtained by the videoscope assisted thoracoscopic biopsy(VATS).
