습지는 다양한 생태계가 형성되어있고, 토양과 물의 정화기능, 폭우방지 및 홍수 완화 등 인간이 살아가는데 중요한 역할을 하고 있다. 이처럼 중요한 기능을 제공하는 습지에 대한 관심이 증가하고 있지만 그에 따른 습지관리 방안에 대한 연구가 미흡한 실정이다. 특히, 습지 조성 후 유지관리 방안을 제시하기 위해서는 습지의 생태환경을 모니터링 하여 분석하는 것이 필요하다.이를 위해 본 연구에서는 비내섬(남한강), 옥포지구(낙동강), 세도지구(금강) 3개의 인공습지를 대상으로 생태환경에 대한 모니터링을 실시하였다. 모니터링 결과, 비내섬 습지는 천이초기단계에서 개척자식물이 유입되는 등 향후 천이도중상태의 이차초지로 천이될 것으로 판단되며, 옥포지구 습지는 안정된 천이과정을 보이고 있으나, 안정화 단계에 도달할 때 까지 지속적으로 변화될 것으로 판단된다. 세도지구 습지는 인위적 교란요인이 적기 때문에 미소입지별로 식생천이에 따라 다양한 식생이 형성될 것으로 판단된다. 본 연구의 결과 향후 봄, 여름이 추가된 사계절을 장기적으로 모니터링 하여 식물상 데이터를 구축할 수 있다면 더 정량적인 식성천이 분석을 할 수 있을 것으로 판단된다.

The purpose of this study is to analyze the industrial structural changes and types of specialized in the shipbuilding cities, which are representative sectors of industrial city decline, and explore regional responses. Most cities designated as special areas for industrial crisis response in 2018 are specialized in shipbuilding. While the shift from prosperity to recession since the 2010s is the main factor, each city has responded differently to the industrial crisis. The analysis, targeting seven shipbuilding cities, shows that regions where large shipyards of major corporations with high industrial competitiveness are located have relatively less decline during business fluctuations, and there is a tendency for a decrease in industrial structural diversity during prosperous periods and an increase during recessionary periods. Based on the resistance and recoverability to industrial crises, the industrial paths of shipbuilding cities are classified into four types. Considering regional industrial structure and competitiveness, it is necessary to develop customized support strategies such as maintaining and declining shipbuilding industries and fostering new alternative industries.

For the application of the diffusion equation, slope height and maximum slope angle are calculated from the plotted slope profile. Using denudation rate as a solution for the diffusion equation, an apparent age index can be calculated, which is the total amount of denudation through total time. Plots of slope angle versus slope height and apparent age index versus slope height are useful for determining relative or absolute ages and denudation rates. Mathematical simulation plots of slope angle versus slope height can generate equal denudation-rate lines for a given age. Mathematical simulations of slope angle versus age for a given slope height, for equal denudation-rate at a particular profile site, and for comparing to other sites having controlled ages.

The purpose of this study is to exploratory analyze the transition pattern of establishments and workers in new growth industries in the metropolitan area from 2010 to 2019 and to identify regional factors affecting the inflow and outflow of new growth industry start-ups. As for the analysis, the original data of the Census on Establishments were used, and spatial data at the sigungu level were constructed based on the inflow and outflow data of the number of new growth industry businesses and workers. For the analysis, the degree centrality of connection to outflow inflow by region was calculated, and an empirical analysis was conducted on regional-level factors affecting the inflow and outflow of new growth industries by applying a negative binomial regression model. According to the results, the new growth industry manufacturing sector was actively relocated in southern Gyeonggi Province, and the new growth industry service sector in Gangnam and Guro-Geumcheon-gu, and the impact of regional-level factors on the inflow and outflow of new growth industry start-ups varies depending on the industry. This study presented implications for regional industrial policies to improve the competitiveness of the local economy by attracting new industries by identifying spatial transition patterns for new growth industries and conducting empirical analysis to identify influencing factors.

Decline of pine forests happens in Korea due to various disturbances such as insect pests, forest fires and extreme climate, which may further continue with ongoing climate change. For conserving and reestablishing pine forests, understanding climate-induced future shifts of pine tree distribution is a critical concern. This study predicts future geographical distribution of Pinus densiflora, using Maximum Entropy Model (MaxEnt). Input data of the model are locations of pine tree stands and their environmental variables such as climate were prepared for the model inputs. Alternative future projections for P. densiflora distribution were conducted with RCP 4.5 and RCP 8.5 climate change scenarios. As results, the future distribution of P. densiflora steadily decreased under both scenarios. In the case of RCP 8.5, the areal reductions amounted to 11.1% and 18.7% in 2050s and 2070s, respectively. In 2070s, P. densiflora mainly remained in Kangwon and Gyeongsang Provinces. Changes in temperature seasonality and warming winter temperature contributed primarily for the decline of P. densiflora., in which altitude also exerted a critical role in determining its future distribution geographic vulnerability. The results of this study highlighted the temporal and spatial contexts of P. densiflora decline in Korea that provides useful ecological information for developing sound management practices of pine forests.

Alvin Toffler는 인류 발전 과정을 세 가지 변화의 물결, 즉 유목 채집 사회에서 농경 사회로의 변화, 산업혁명에 의한 농경 사회에서 산업 사회로의 변화, 그리고 1950년대부터의 후기 산업화 사회로의 변혁으로, 산업 사회에서 정보 사회로의 변혁이 일어나기 시작했으며 탈대량화, 다양화, 지식기반 생산과 변화의 가속이 시작된 시기였다. Herman Maynard와 Susan Mehrtens는 ICT (Information Communication Technology: 휴대폰 등), 인터넷의 발달로 제4의 물결이 시작되고 있다고 주장한다. 이전의 사회 변혁들은 물질 생산이 따르는 가시적인 변혁들이었으나, 디지털 혁명은 시민사회의 참여 확대를 통한 민주주의의 진화된 형태를 가능하게 하고 있다. 지금 우리가 경험하고 있는 제4의 물결의 시작은, 시민사회의 정책 참여와 견제가 효과적이고 효율적으로 이루어지기 시작하는 초고도 정보화 사회의 시작을 의미하며, 정책 결정 자들은 정책 결정 과정에서 그들이 보유하던 절대 영향력의 일부분을 시민사회에 이양됨을 막을 수 없을 것이다. 이러한 대변혁의 시대에 관료주의, Digital Divide, 그리고 시민 참여와의 상관관계를 이해하는 것은 매우 중요하다. 본 논문에서는 시민 참여에 대한 관료주의의 방침과 태도, 제4의 물결의 정책 민주화와 Digital Divide로의 영향 분석을 통하여 정책 결정 자들과 그들의 환경으로의 파급 효과를 논증한다. 본 연구는 이러한 분석과 논증을 통하여, 정책조직들과 시민사회와의 신세기의 바람직한 동반자적 입지 구축에 기여 할 것이다.

Recently, airport competitiveness measure is not only passenger and cargo throughput but also value-added activities of their hinterland and airport city. That is, airport competitiveness comes from airport versus airport to airport with their own-supplied city and hinterland connected with airport to provide diversified functions. This study surveyed and analyzed how to form a cluster focused on Incheon International Airport and what are important factors to form of cluster in achieving competences. These clusters need government's political support. In this case, there was a shortage of specialized human resources in competent local suppliers, and limited informations sharing.
