1990년 중반 이후 우리나라에서는 녹색농촌체험마을(농림부), 아름마을다꾸기(행자부), 새농어촌건설사업(강원도) 등 중앙부처 혹은 지방정부의 주도로 다원적 농촌발전과 주민참여를 중시하는 새로운 시범사업들이 도입되고 있다. 그러나 60∼70년대 산업화ㆍ공업화 위주의 정책으로 인해 농촌의 청ㆍ장년층이 도시부문으로 유입되었고, 80년대 이후 농촌에 대한 사회적 요구가 변화되었고, 농촌지역의 인구사회학적 구성의 변화로 농업ㆍ농촌의 신규 인력 대체가 어려워지면서 2000년 농촌인구 중 여성인구 50.2%, 65세 이상 노인인구 14.7%를 차지하는 즉 도시 노인 인구의 2.7배나 되는 인구구조를 이루게 되었다.(중략)

최근 도시발달과 인구증가로 인하여 수자원의 중요성이 더욱 커지고 있으며 이를 효율적으로 이용하고자하는 노력은 계속되고 있다. 또한 전 세계가 가뭄과 홍수 등 물과 관련된 재해를 예방하기 위하여 지속적인 수자원계획관리가 이루어지고 있으며, 특히 댐은 수자원의 효율적인 관리와 안정적인 용수공급을 위하여 건설된 것으로서 유역의 수문특성에 따른 변동성이 고려되어야 한다. 따라서 댐의 최적운영을 위해서는 정확한 강우 예측과 이에 따른 유입량 예측이 선행되어야 하며, 유입량 예측을 위한 강우-유출과정을 모형화 하여야 한다. 그러나 모형화에 따르는 복잡한 과정과 수문자료의 비선형성과 비정규성으로 인하여 많은 오차가 발생할 수 있다. 본 연구에서는 이러한 문제점을 개선하기 위하여 임하댐 유역에 신경망 이론을 강우-유출모형에 수학적으로 모형화 하였으며, 이를 통하여 효율적인 댐 운영을 위한 유입량 예측기법에 관한 기초연구를 수행하였다.

Purpose: The purpose of this study is to analyze the impact of regional characteristics on population movement on the Seoul metropolitan areas. Method: To this end, 66 basic entities in the Seoul metropolitan area were divided into three regions by analyzing the demographic movement data from 2010 to 2016 and the factors for determining population movement within and between regions were identified by applying a stepwise regression technique. Result: The major analysis confirmed that the increase in the number of apartments in all areas of the Seoul metropolitan area, the increase in the number of single-family homes, the increase in the number of employees, the increase in manufacturers, the growth rate of knowledge, culture, and leisure industries, the increase rate of GRDP, and the opening of new subway stations. In particular, the growth rate of the number of apartments, the growth rate of the knowledge, culture and leisure industries, the increase rate of GRDP, and the opening of new subway stations played a positive role in increasing population inflow. Conclusion: The result showed that by region, the growth rate of knowledge, culture and leisure industries contributed greatly to the inflow of population in the first region, and that the opening of new subway stations and the increase of GRDPs were the main factors. The increase in the number of apartments and subway stations were the main factors in the three areas.

This paper analyzed what determines affected FDI inflow of developing countries by using panel data from 65 lower-middle income and low income countries(Asia, Africa and Latin America). Empirical results showed that economic growth has a more positive impact on a middle income country than a lower one, and has a better impact on the Asian continent than others. Trade has similar effect on lower and middle income countries, respectively. ODA, however, has a negative effect on both sides, regardless of the continent. Industrial value added rate and labor force have a positive effect on FDI in low and middle income countries. Infrastructure was found to be a significant impact on FDI inflows in lower-middle income countries than in low income countries. There is no geographically significant difference except Africa.

As an improvement on qualities of lives and a change in the habitual ways people eat require more water to be used for daily lives, the amount of wastewater generated from our usual lives is also expected to be in higher rate of consumption. The unit loading factor of sewage flow-rate based upon the number of people living in the apartment complexes has to be found for the design of the sewage or wastewater treatment facilities. These data are definitely thought to be useful for the plans to operate the sewage treatment facilities and for those to establish the plans toward a management of water qualities. Thus this study has shown that the data regarding the water supplies and the number of apartment residents within the 123 districts of KNHC(Korea National Housing Corporation) were collected and analyzed. One district in Seoul and the other local district were chosen an the experimental sites for th hourly, daily, weekly and seasonal measurements of the influent sewage flow-rate. The unit loading factor of influent sewage flow-rate were determined through the comparison of total sewage amount in combination with the number of people residing in two apartment complexes with supplying amount of water.

한강, 금강, 낙동강 및 영산강은 우리나라의 4대강으로 남해와 서해로 유입되고 있다. 강 하류인 하구(estuary)는 육지와 해양의 점이지대로서 담수와 해수가 혼합되는 지역이며, 육지로부터 유입된 물질과 해양학적인 상호작용의 결과로 독특한 환경을 유지하고 있다. 하구환경에는 육지의 침식작용과 인간활동 등에 의해 야기된 많은 다양한 물질들이 수계를 통하여 하구에 유입되어 퇴적되고 있다. 그러나 인구 급증과 급격한 산업화와 도시화에 기인된 오염물질의 하천유입은 우리나라의 주요 하천인 한강, 낙동강, 금강 및 영산강을 포함하여 크고 작은 강과 하천들을 오염시켜 사회ㆍ경제적으로 큰 문제를 야기하고 있는 실정이다.(중략)

This study aim to examine the optimum population in Korea, which has the lowest fertility rate in the world. This study has significance because this rapid decline in the fertility rate is expected to bring the decrease of the population and unbalance in the population composition in Korea. From the social welfare perspective, the optimum population is guided by maximization of the social welfare level per person or the social welfare level in a society. The optimum population can be defined as follows: The proportion of older adults 65 and over is 15-17%, the proportion of work force is 64-69%, the index of aging is 72-104. Within the current population and population composition, the optimum population is estimated as 4.85-4.95 million. These findings imply that we need to remove causes of low fertility rate and prepare for policies encouraging immigration of labor force from foreign countries. In addition, policies and programs where children can be grown up in good environments and women and older adults can participate in labor force should be established.

In 2005, the selection of 10 innovation cities was completed, and since 2013, public institutions began relocating to innovation cities. As a policy aimed at promoting balanced regional development, there were significant expectations from the regions. However, although the population moving to innovation cities has increased, it remains to be seen how much inflow is from the capital region and what spatial characteristics exist nationwide. Therefore, this study aims to analyze whether the innovation cities are fulfilling their roles by examining the patterns of inflow from the capital region and the spatial characteristics, and to reassess the policy direction for future innovation cities. We utilized the Microdata Integrated Service (MDIS) provided by Statistics Korea from 2013 to 2021. For the data collection reasons, we focused on analyzing the three cities. The results showed that in the initial stages of innovation city development, there was a significant influx of population from the capital region, leading to some effects on population dispersion and balanced regional development. However, over time, a phenomenon emerged where more people started to move back to the capital region, indicating a problematic trend. Furthermore, the Gyeongbuk Innovation City and Gwangju-Jeonnam Innovation City showed similarities in terms of reasons for migration, age of householder, and number of household members. However, the Gyeongnam Innovation City exhibited distinct characteristics compared to the other two cities. While the reasons for this phenomenon may be diverse, the current situation suggests that the goal of achieving "balanced national development" has reached its limits. Therefore, urgent measures need to be taken for improvement that take regional characteristics into account. Furthermore, in designing the second phase of the public institution relocation plan is required to avoid repeating the same issues and ensure a more thoughtful approach.
