Because of differences in thoughts and ideology, our country, Korea has been deprived of national unity for some thirty years of time and tide. To achieve peaceful unification, the cultivation of national strength is of paramount importance. This national strength is also essential if Korea is to take rightful place in the international societies and to have the confidence of these societies. However, national strength can never be achieved in a short time. The fundamental elements in economic development that are directly conducive to the cultivation of national strength can be said to lie in -a stable political system, -exertion of powerful leadership, -cultivation of a spirit of diligence, self-help and cooperation, -modernization of human brain power, and -establishment of a scientific and well planned economic policy and strong enforcement of this policy. Our country, Korea, has attained brilliant economic development in the past 15 years under the strong leadership of president Park Chung Hee. However, there are still many problems to be solved. A few of them are: -housing and home problems, -increasing demand for employment, -increasing demand for staple food and -the need to improve international balance of payment. Solution of the above mentioned problems requires step by step scientific development of each sector and region of our contry. As a spearhead project in regional development, the Saemaul Campaign or new village movement can be cited. The campaign is now spreading throughout the country like a grass fire. However, such campaigns need considerable encouragement and support and the means for the desired development must be provided if the regional and sectoral development program is to sucdceed. The construction of large multipurpose dams in major river basin plays significant role in all aspects of national, regional and sectoral development. It ensures that the water resource, for which there is no substitute, is retained and utilized for irrigation of agricultural areas, production of power for industry, provision of water for domestic and industrial uses and control of river water. Water is the very essence of life and we must conserve and utilize what we have for the betterment of our peoples and their heir. The regional and social impact of construction of a large dam is enormous. It is intended to, and does, dras tically improve the "without-project" socio-economic conditions. A good example of this is the Soyanggang multipurpose dam. This project will significantly contribute to our national strength by utilizing the stored water for the benefit of human life and relief of flood and drought damages. Annual average precipitation in Korea is 1160mm, a comparatively abundant amount. The catchment areas of the Han River, Keum River, and Youngsan River are $62,755\textrm{km}^2$, accounting for 64% of the national total. Approximately 62% of the national population inhabits in this area, and 67% of the national gross product comes from the area. The annual population growth rate of the country is currently estimated at 1.7%, and every year the population growth in urban area increases at a rising rate. The population of Seoul, Pusan, and Taegu, the three major cities in Korea, is equal to one third of our national total. According to the census conducted on October 1, 1975, the population in the urban areas has increased by 384,000, whereas that in rural areas has decreased by 59,000,000 in the past five years. The composition of population between urban and rural areas varied from 41%~59% in 1959 to 48%~52% in 1975. To mitigate this treand towards concentration of population in urban areas, employment opportunities must be provided in regional and rural areas. However, heavy and chemical industries, which mitigate production and employment problems at the same time, must have abundant water and energy. Also increase in staple food production cannot be attained without water. At this point in time, when water demand is rapidly growing, it is essential for the country to provide as much a reservoir capacity as possible to capture the monsoon rainfall, which concentarated in the rainy seaon from June to Septesmber, and conserve the water for year round use. The floods, which at one time we called "the devil" have now become a source of immense benefit to Korea. Let me explain the topographic condition in Korea. In northern and eastern areas we have high mountains and rugged country. Our rivers originate in these mountains and flow in a general southerly or westerly direction throught ancient plains. These plains were formed by progressive deposition of sediments from the mountains and provide our country with large areas of fertile land, emminently suited to settlement and irrigated agricultural development. It is, therefore, quite natural that these areas should become the polar point for our regional development program. Hower, we are fortunate in that we have an additional area or areas, which can be used for agricultural production and settlement of our peoples, particularly those peoples who may be displaced by the formation of our reservoirs. I am speaking of the tidelands along the western and southern coasts. The other day the Ministry of Agriculture and Fishery informed the public of a tideland reclamation of which 400,000 hectares will be used for growing rice as part of our national food self-sufficiency programme. Now, again, we arrive at the need for water, as without it we cannot realize this ambitious programme. And again we need those dams to provide it. As I mentioned before, dams not only provide us with essential water for agriculture, domestic and industrial use, but provide us with electrical energy, as it is generally extremely economical to use the water being release for the former purposes to drive turbines and generators. At the present time we have 13 hydro-electric power plants with an installed capacity of 711,000 kilowatts equal to 16% of our national total. There are about 110 potential dams ites in the country, which could yield about 2,300,000 kilowatts of hydro-electric power. There are about 54 sites suitable for pumped storage which could produce a further 38,600,000 kilowatts of power. All available if we carefully develop our water resources. To summarize, water resource development is essential to the regional development program and the welfare of our people, it must proceed hand-in-hand with other aspects of regional development such as land impovement, high way extension, development of our forests, erosion control, and develop ment of heavy and chemical industries. Through the successful implementation of such an integrated regional development program, we can look forward to a period of national strength, and due recognition of our country by the worlds societies.

기술경쟁이 심화되고 있는 오늘날 신기술에 대한 선도적 위치의 선점이 중요하다. 선도적 위치의 선점과 적정시점에 기술 획득·관리를 위해 이해관계자들은 지속적으로 기술에 대한 탐색활동을 수행한다. 이를 위한 참고 자료로서 가트너 하이프 사이클(Gartner Hype Cycle)은 중요한 의미가 있다. 하이프 사이클은 기술수명주기(S-curve)와 하이프 수준(Hype Level)을 결합하여 새로운 기술에 대한 대중의 기대감을 시간의 흐름에 따라 나타낸 그래프이다. 새로운 기술에 대한 기대는 기술사업화뿐만 아니라 연구개발 투자의 정당성, 투자유치를 위한 기회의 발판이 된다는 점에서 연구개발 담당자 및 기술투자자의 관심이 높다. 그러나 산업계의 높은 관심에 비해 실증분석을 시도한 선행연구는 다양하지 못하다. 선행문헌 분석결과 데이터 종류(뉴스, 논문, 주가지수, 검색 트래픽 등)나 분석방법은 한정적이었다. 이에 본 연구에서는 확산의 주요한 채널이 되어가고 있는 소셜네트워크서비스의 데이터를 활용하여 'Gartner Hype Cycle for Artificial Intelligence, 2021'의 단계별 기술들에 대한 집단구조(커뮤니티)의 특성과 커뮤니티 간 정보 확산패턴을 분석하고자 한다. 이를 위해 컴포넌트 응집규모(Component Cohesion Size)를 통해 각 단계별 구조적 특성과 연결중심화(Degree Centralization)와 밀도(Density)를 통해 확산의 방식을 확인하였다. 연구결과 기술을 수용하는 단계별 집단들의 커뮤니케이션 활동이 시간이 지날 수록 분절이 커지며 밀도 역시 감소함을 확인하였다. 또한 새로운 기술에 대한 관심을 촉발하는 혁신태동기 집단의 경우 정보확산을 촉발하는 외향연결(Out-degree) 중심화 지수가 높았으며, 이후의 단계는 정보를 수용하는 내향연결(In-degree) 중심화 지수가 높은 것으로 나타났다. 해당 연구를 통해 하이프 사이클에 관한 이론적 기초를 제공할 것이다. 또한 인공지능기술에 대한 기술관심집단들의 기대감을 반영한 정보확산의 특성과 패턴을 소셜데이터를 통해 분석함으로써 기업의 기술투자 의사결정에 새로운 시각을 제공할 것이다.
