      • 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.

        교사 평가제의 쟁점 연구

        고영호,김병희 경북대학교사범대학부속 중등교육연구소 2005 중등교육연구 Vol.53 No.1

        본 연구는 공교육 회생의 주된 정책방안의 하나로 논의되고 있는 교사평가제의 주요 쟁점들을 검토하고, 그 대안을 제시하기 위한 것이다. 여기에서 다루어진 내용은 평가의 목적, 평가의 주체, 평가의 내용 영역에서 논의되고 있는 주요 쟁점들로서, 그 구체적인 여러 논점들이 갖는 이론적, 실천적 함의들을 검토하고 타당성을 분석하였다. 이런 분석을 바탕으로, 타당한 교사평가제가 시행되기 위해서는 교사의 직무수행에 대한 합리적인 평가방법과 평가도구의 개발과 함께 교사평가에 대한 교육적철학적 문제들에 대한 검토가 필수불가결하다는 점을 제안하였다. The study aims to analyze the controversial points at issue relating to the teacher evaluation system and get better ideas or plans enough to cope with the problems. ChapterI introduces the background situations where the teacher evaluation system has begun to be discussed. In ChapterII, the purposes of the system are discussed in the aspect of teacher's self-development, the education improvement in quality, personnel management, promotion, teacher grading, reward systems and filtering out the unsuitable teachers. ChapterIII deals with the topic of who evaluates the teachers. It can be achieved by the teachers themselves evaluating their colleagues. Teachers of a higher position such as a principal can do it, Or the evaluation by parents or students is also possible. All these cases are respectively considered in this chapter. In ChapterIV, the discussion is developed to analyze the issue concerning what should be evaluated, focusing on the administrative abilities and basic qualifications as a teacher such as teaching and counseling skills. Finally, ChapterV draws the conclusions from all of the viewpoints involved in the light of validity, objectivity and reliability. The suggestion made here indicates that the evaluation by students is most suitable as a way of teacher evaluation, for it helps the teachers improve their teaching skills.

      • 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.

      • 韓國經濟와 資本自由化 戰略

        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.

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.)
