The purpose of this study is to understand the vegetation structure and ecological characteristics of the coastal forest Pinus thunbergii community in Busan Metropolitan City (BMC) and to establish reference information for the management of the coastal forest in BMC in the future. We set up 97 plots with an area of $100m^2$ each for the analysis and investigation of the vegetation characteristics. The analysis using the TWINSPAN and DCA techniques found seven community groups: Pinus thunbergii-Quercus aliena community, Pinus thunbergii-Eurya japonica(1) community, Pinus thunbergii-Eurya japonica(2) community, Pinus thunbergii-Quercus serrata community, Pinus thunbergii-Camellia japonica(1) community, Pinus thunbergii-Camellia japonica(2) community, and Pinus thunbergii-Eurya japonica-Camellia japonica community. According to the analysis of vegetation structure, Pinus thunbergii was a main dominant species at the canopy layer in all sites while Eurya japonica and Camellia japonica were dominant species at the understory layer. Pinus thunbergii-Quercus serrata community is predicted in the forest succession because of the competition between Pinus thunbergii and Quercus serrata in the canopy layer and the understory layer. As such, it is necessary to observe changes by continually monitoring this community. Tree species with strong salinity tolerance, including Pinus thunbergii, have formed community groups because of the environmental characteristics of coastal forests, strong with salinity tolerance species are forming community groups. Therefore, all community groups except for the Pinus thunbergii-Quercus serrata community will maintain the current vegetation structure unless drastic environmental changes occur.

This study investigates the wage determination process of regional labor markets in order to understand the regional dimension of labor market processes in Korean metropolitan cities. Since the financial crisis in late 1997, the interplay between labor market restructuring such as unemployment and skill polarization and income disparity has been shaped by the labor market process in the metropolitan cities. This is also closely related to the fact that both industrial restructuring and expanding information technologies in the metropolitan region have reshaped the labor demand structure and finally resulted in structural unemployment due to skill mismatch and spatial mismatch and wage inequality across different occupations. In addition, since wage determination process clearly has a regional dimension, wage determination and its influence on income profile in a certain regional labor market need to be understood by investigating its labor market characteristics including labor supply and demand structure, industrial changes, changing unemployment, etc. This is why labor market policy as a regional policy needs to be redefined and it can be much enhanced by geographical investigation on regional labor market.

기후변화로 인한 다양한 문제는 전 세계적인 사항이며, 그 중 물과 관련한 사항은 가장 큰 문제로 주시되고 있다. 물 관련 인프라와 산업이 미비한 국가에서는 다양한 방법을 통해 자국의 물 공급 등 수자원 문제를 해결하려 하고 있으며, 이는 국내에서 물 산업의 해외진출 기회로 작용하고 있다. 본 연구에서는 해외 수자원 인프라 구축으로 인한 실제적인 효과성을 분석하고자 스리랑카 Galle 광역시 상수도 사업을 대상으로 하여 다양한 효과적 측면 중 사회적 측면인 지역주민의 삶의 질 향상, 경제 활성 기여, 성 인지도 제고, 지속가능성 제고에 대해 평가하였다. 지역주민의 삶의 질 향상은 현지의 통계자료 분석, 관계자 면담 등을 통해 취수시간 감소 및 깨끗한 물 공급 달성과 수인성 질병 감소를 조사하였으며, 경제 활성화 기여는 관련 문헌조사와 주민을 대상으로 한 설문조사를 통하여 그 여부를 파악하였다. 성 인지도 제고는 관계자 면담 및 설문조사를 수행하여 여성가사노동 감소 및 여성의 경제활동 참여 증가정도 및 기여도를 분석하였다. 지속가능성 제고는 관련 정책 개선여부에 대하여 조사 및 분석을 수행하였다. 분석 결과 깨끗한 물 공급이 사업 착수 전보다 원활해 졌으며, 수인성 질병 중 하나인 이질 환자가 감소되어 삶의 질이 향상되었다고 사료된다. 또한 상수도 사업을 통한 기간시설의 용수공급이 원활해지고 용수부족 해소 및 관광산업 등 서비스산업 활성화를 촉진시킴으로서 경제 활성화에 기여했다고 판단할 수 있다. 성인지도 제고에 대한 분석은 원활한 물 공급으로 인하여 여성의 물 관련 가사노동 감소에 기여하였으나 여성의 사회참여 기여에 많은 영향을 미치지는 못한 것으로 사료된다. 마지막으로 상수도시설 확충으로 인하여 용수보급률이 증가하고 이에 따라 관련제도를 개선하여 담당 기관의 재무건전성을 제고시킴으로서 지속가능성을 향상시켰다고 할 수 있다. 스리랑카 Galle 광역시 상수도사업의 이러한 성공적인 결과는 해당 국가의 개발정책과 높은 의지와 인구가 밀집되어있고 인구에 비해 급수보급률이 낮은 지역, 관광서비스 산업 밀집지역이 사업대상지로 선정된 요소가 작용하였다고 할 수 있다. 본 연구 결과를 통해 추후 해외 수자원 사업 진출 시 해당국가의 개발정책의지와 대상지역의 현황, 사업으로 인한 다양한 영향력을 고려한다면 성공적인 사업을 수행할 수 있을 것이다.

This paper analyzes the relationships among the energy consumption, renewable energy production, real gross regional domestic product(GRDP), and greenhouse gas(GHG) emissions. It uses the metropolitan city and province level data for Korea from 2010 to 2018, employing a panal vector autoregressive(VAR) model. We find that an increase in energy consumption has a limited impact on boosting renewable energy production or gross regional domestic product, while it leads to an increase in greenhouse gas emissions. A rise in renewable energy production can increase gross regional domestic product, but it has no meaningful effects on energy consumption and the reduction of green house gas emissions. Our finding indicates that it is crucial to expand the supply of renewable energy as well as to decrease energy consumption in order to achieve the goal of reducing greenhouse gas emissions and reaching economic growth.

In this study, the location and network hierarchy of the seven major test and certification institutions in Korea were analyzed. First, like other APS, the test and certification institutions are concentrated in the metropolitan area, and the spatial spread of the branch is developing. Second, unlike other APS, branches do not accumulate in large cities. It is deeply related to regional economic geography characteristics such as proximity to manufacturers and specificity of regional strategic industries. Third, despite the spatial spread, workers are concentrated in the metropolitan area. Fourth, urban-regions are mainly formed between the metropolitan area of test certification and the Chungbuk(Cheong) area.

This study uses a continuous autoregressive (CAR) model to analyze daily average temperature in six Korean metropolitan cities. Data period is Jan. 1, 1954 to Dec. 31, 2010 covering 57 years. Using a relative long time series reveals that the linear time trend components are all statistically significant in the six cities, which was not shown in previous studies. Particularly the plus sign of its coefficient implies the effect on Korea of the global warming. Unit-root test results are that the temperature time series are stationary without unit-root. It turns out that CAR(3) is suitable for stochastic component of the daily temperature. Since developing suitable continuous stochastic model of the underlying weather related variables is crucial in pricing the weather derivatives, the results in this study will likely prove useful in further future studies on pricing weather derivatives.

The purpose of this study is to analyze the effect that consumption patterns of human affect the ecosystem using analysis of ecological footprint(EF) and assessment of ecosystem service value in Daegu Metropolitan Area. The data for analysis were constructed from statistical yearbook of each city and average of public land price on land category. According to the EF analysis on city, total EF of Goryeong was showed the highest by 3.3052gha in 2007. However, total EF of Daegu was assessed the lowest by 2.0134gha among 8 cities. In the results of ecological deficit, 7 cities except Gunwi were assessed by condition of ecological deficit and had exceeded environmental capacity until 2007. Specially, it was analyzed that Daegu may need additional area more than about 30 times to maintain the present consumption patterns. On the one side, the results of analysis of ecosystem service value in Daegu were assessed that citizens of Daegu have borrowed about 1,078.6 million wons to ecosystem per year and one person.

Photographic records capturing the changes of a city are vital parts of local history archives. They were, however, not collected properly for the local history archives even by local governments. Therefore, as a solution for this problem, seven major cities (Seoul, Incheon, Gwangju, Ulsan, Daejeon, Busan, and Daegu) initiated the urban landscape documentation project for archiving the photographic records of each city. This study investigated the current status of the urban landscape documentation project and found that Daegu metropolitan city's project only holds some of the contest photos and a few old photos from the local government. A proper donating process is urgently needed to preserve valuable photographic records of Daegu, and this study aims solutions for the Daegu metropolitan city's urban landscape documentation project to improve the acquisition methods of photographic records. This study suggests the process for photographic records donation from citizens and a metadata set for donated photographs.
