        This study was undertaken to classify and describe the riverside vegetation around the mainstream of Nak-tong River, Korea by phytosociological method of the Z-M school. The field survey were carried out in 73 plots from March, 1995 to October, 1996. The vegetation data obtained were classified by the tablework. As a result, the following vegetation units were recognized: A. Phragmites japonica community B. Phragmites japonica - Salix gracilistyla community C. Phragmites japonica - Phragmites communis community C-a. Typical subcommunity C-b. Ligustrum obtusifolium subcommunity D. Salix gracilistyla - Phragmites communis community D-a. Typical subcommunity D-b. Capsella brusa-pastoris subcommunity D-c. Scirpus fluviatilis subcommunity E. Rumex japonica community F. Carex pumila community G. Agropyron tsukushiense var. transiens community Also the relationship of the vegetation units with their environments such as riverbed height, topography, soil class etc. was discussed here.

      • 韓國의 經濟開發과 社會指標

        高永鎬 大田大學校 1982 論文集 Vol.1 No.1

        I am going to look back upon the traits of the economic developments achieved through 1960's to 1970's in korea and analyze some of merits and demerits that happened during those periods. According to this analysis, I'll synthesize my own opinion as follows : 1. The priority of development has changed from social over-head capital to light industry and heavy industry, therefore we faced to the unbalance of industrial structure. Equity of distribution has been disturbed by high price mind and products which resulted from pursuit of planned aims. 2. The deficit in balance of payment caused by pursuing the export-drive policy was not reduced that elasticity of national economic operation is rigidity and some of large enterprises shared the domestic market oligopolly. 3. Perfect self-sustained situation of national economy became far a way be enormous induction of foreign capital. 4. Development of technical-intensive industry was delayed by emphasizing the scale of economy too much. 5. Development of social welfare was delayed by other economic projects. Secondly, I am going to anticipate the situation of economic development during 1980's. Thirdly, as the economic development is being accomplished there happend problems of the natinal welfare by increasing national needs. When I analysise the problems, I am going to arrange their order as follows : ① GNP ( Gross National Products ) ② MEW ( Measures of Economic Welfare ) ③ NEW ( Net Economic Welfare ) ④ S I ( Social Indicator ) Particulary I am going to describe with detail about social Indicator, which is significant conception used frequently for the measurement of national welfare level. In describing Social Indicator, I'll explain the items of it as follows : 1. Historical background 2. Conception 3. Comparative study ① United Nations ② OECD ③ United States and Japan ④ South Korea Next, I would like to describe the fuction and problems of social indicater and lastly suggest the basic directions of national welfare as follows : 1. Whoever works hard can have the conviction that He can be free from starvation, shabby-clothing and meager shelter. 2. Everyone should be free from ignorance and disease equally and allowed opportunity to pursue happiness under the same conditions. 3. Everyone should be free from the fear of crime, disaster and compensated justly for his contribution and services. 4. Everyone should not be treated unjustly by education, sex and wealth and given equal opportunity socially and economically. In conclusion, I want that we are going to enjoy the "Equity of Society".

      • 낙동강 본류 하변의 식물상에 관한 연구

        고재기,조영호 대구한의대학교 기초과학연구소 2003 基礎科學 Vol.7 No.2

        본 조사에서 기록된 관속식물은 69 科 174 屬 227 種 40 變種 2 品種으로 총 269 種이 조사되었다. 생활형의 구성은 남한지역 전체와 비교할 때, 지상식물, 지중식물 및 지표식물의 비율이 낮았고, 반지중식물, 1년생식물 및 수생식물의 비율이 현저히 높게 나타났다. 본 조사 지역에서 얻어진 귀화식물은 전체 출현종의 8.55%로써 23종 이 출현하였다. 낙동강 본류의 수생식물은 총 16과 20속 31종 4변종을 총 35종류가 조사되었으며 정수성이 14종(40.0%)으로 가장 많았으며 침수성 11종(31.4%), 부엽성 7종(20.0%), 부유성 3종(8.6%)의 순으로 나타났다. 수생식물의 분포는 대구상류에 16 종, 대구 하류에 26종으로 하류로 갈수록 많이 출현하고 있으며, 침수식물인 검정말 (Hydrilla verticillata)이 우점종으로 관찰되었다. This study was undertaken to describe the riverside flora in 73 plots around the mainstream of Nak-tong River, Korea from March, 1995 to October, 1996. The field survey were carried out through the process of direct collection on actual vegetation and drying, fixation and identification of each specimen. The vascular plants around the mainstream of Nak-tong River were consisted of 269taxa; 69 families, 174 genera, 227 species, 40 varieties, 2 forms. Compared with Raunkiaer's lifeform spectrum, the percent of phanerophyte, geophyte and epiphyte were lower and hemicryptophyte, hydrophyte and therophyte were higher remarkably in spectrum of this riverside flora than spectrum of South Korea. The Korean endemic plants are 5 taxa and naturalized plants are 23 taxa. The percent of species number of naturalized plants around the mainstream of Nak-tong River per total species number of naturalized plants in South Korea is 12.8%. The hydrophytes around the mainstream of Nak-tong River were consisted of 35taxa; 16 families, 20 genera, 31 species, 4 varieties and the composition of hydrophytes by life cycle were 10 emergent hydrophytes, 5 floating-leaved hydrophytes, 13 submerged hydrophytes, 3 free-floating hydrophytes and dominant species in hydrophytes was Hydrilla verticillata And the subsidiary knowledge from this study will provide practical information on the study for biodiversity and habitat conservation.

      • 치과용 세라믹스의 제조 및 특성 (Ⅰ)

        고영호,한복섭,이준희 동아대학교 공과대학 부설 한국자원개발연구소 1993 硏究報告 Vol.17 No.2

        It has been investigated the Sintering Characteristics and Microstructure after the Manufacture of Dental Ceramics for Artificial Dental Tooth(Dental Crowns) in Dentistry. The Manufacture of High Thermal Expansional Leucite Crystals has been made by not Conventional Melting Process, but Sol-Gel Process, and composited with Class Frit that has low melting point to get Transparent Sintering Materials. The Crystal Forming Temperature of Leucite manufactured by Sol-Gel Process has been observed after Heat Treatment at various Temperatures. In Addition, The Manufacture Process is simpler than Conventional Melting Process and could be able to manufacture at about 400℃ low Temperature. Glass Frit that has low melting point was fabricated with about 10~30㎛ homogeneous amorphous Powders by means of Ball Milling and was transparent When fired. The Sintering Temperature could be controlled in accordance with the Powder Mixture of Leucite and Glass Frit. The Volume Fraction of Leucite Crystals in Glass Matrix has been increased by the appropriate Heat Treatment of Dental Porcelain.

        高永鎬 大田大學校 1983 論文集 Vol.2 No.1

        Korean economy has confronted with another task in the applying process of his fifth fiveyear economic plan. The primary task is to induce more foreign capital; this is very urgent and important issue in korean economy. That is the reason why more questions are emerged in borrowing foreign capital and korea needs more foreign loan in his economic development activities. After korean government officially announced the fourth stage driving direction in liberalization of capital, It expressed to achieve it’s goal in 1980’s. From this turning point, I will study the strategies in liberalization of capital as follows; Chapter 1. Conception arrangement Chapter 2. Data Analysis Chapter 3. Preceding conditions Chapter 4. Experience of foreign countries Chapter 5. Exhibition of capital liberalization policies Chapter 6. Controversial problems and strategies Chapter 7. Conclusion I would like to explain these seven chapter as follows ; 1. The definition, importance and motivation of this problem are described in conception arrangement chapter. 2. Data Analysis chapter will deal with GNP, percapiter GNP, industrial structure, balance of payment, foreign exchange reserve, general, prices, prime, prime rate, export and import, capital market and listed limitted companies. 3. Preceding condition chapter will show ①Liberalization of trade ②Liberalization of foreign exchange ③ The stabilization of Balance of payment ④ Self-regulation of general prices, prime rate, foreign exchange, etc. ⑤ Foundation of capital market. 4. The background, process and future of liberalization in Japan and Brazil will be described in the experiences of foreign countries chapter. 5. The exhibition of liberalization chapter will be described as follows: ① Comparative study of three means; stocks, bonds and returning bond ② Driving directions of liberalization with questionaires to securities company. 6. Six controversial problems and several strategies are described in chapter 6. 7. In conclusion chapter, I will summarize as follows: ① The policies of the liberalization of capital must be treated cautiousely owing to the character of it’s irreversibility. ② Three stages must be classified in handling of returning bond of International investment. ③ The liberalization of capital will be possible at the time when economic movement will be developed by autonomous parameters.(prime rate, general prices, foreign exchange etc.)
