본 연구는 최근 논의되고 있는 신지역지리의 방법론에 근거하여 지역에 대한 역사지리적 접근의 가능성을 모색하였다. 먼저, 지역지리학의 연구방법에서 구체적 총체성에 대해 살펴보고 구체적 총체성으로서의 지역연구가 신지역 지리 방법론에서 이루어지고 있음을 살펴보았다. 구체적 총체성으로서의 지역연구는 보편적인 사회적 변동의 프로세스와 지역을 고유한 것으로 생산 재생산하는 과정 사이에 상호관련성이 있다는 관점을 취하며 지역을 역동적으로 변화하는 역사적 단위로 본다. 지역의 변화 또는 시간개념에 대한 고려는 지역현상에 대해 지속과 불연속의 변증법 속에서 연구함을 의미한다. 지속과 불연속의 변증법은 지역에서 불연속을 초래한 계기나 현상을 포착하고 지속과 불연속의 연결고리를 찾아 상호관련성을 찾고자 한다. 자본주의의 역사지리에서 봉건제로부터 자본주의로의 이행 시기는 연속과 불연속을 동시에 포착할 수 있는 시기로 본다. 이 시기의 연구대상으로 삼을 수 있는 것은 자본주의로의 이행에서 화폐와 시장, 도시연구이다. 화폐는 자본주의로의 전환을 대표하는 것이며 시장과 도시는 봉건제로부터 지역주의로의 이행에서 진정한 의미를 갖는다. 도시는 화폐와 시장의 경제활동이 집중된 곳으로 자본주의 경제의 특성을 파악할 수 있는 지역이다. 한국사회에서 개항에서 일제강점기까지의 화폐와 시장, 도시에 대한 역사지리적 연구는 자본주의의 형성과정과 관련되어 연구되어질 수 있다. 한국에서 화폐와 시장이라는 렌즈를 통해 식민지 도시를 연구하는 것은 자본주의로의 이행시기에 대한 역사지리적 접근에 있어 구체적 총체성을 담아 낼 수 있는 주제이다.

The purpose of this study is to verify the economic effects of the on going Korea-EU FTA negotiations upon the regional economy and to present some strategic economic countermeasures to deal with the forthcoming changes on the economic environments. In comparing with the industrial structure between Korea and EU, due to the different specific part of their industrial competitiveness both parts would have complementary cooperative transactions and trade as well. And also Korea and EU would have the similar understanding of the importance of the field of agriculture and service in accordance with the economic standpoint respectively. The level of degree and magnitude of the effect of Korea-EU FTA upon the regional economy would be decided in accordance with the industrial structure and the level of income of the regional economy. We are not to confirm and specify the economic influences of Korea-EU FTA negotiations on the economic conditions of Gangwon province but to prepare rational economic countermeasures fit to its structural character. One of the political strategies that might be feasible is the inflow of foreign direct investment from the developed European countries to the regional economy. This developing model would mean a new experiment to activate any regional economy and a new formation of the policy of economic growth.

The purpose of this paper is to analyze factors affecting the net income of regional and industrial fisheries cooperatives in South Korea using panel data. This paper utilizes linear or GLS regression models such as pooled OLS model, fixed effects model, and random effects model to estimate affecting factors of the net income of regional and industrial fisheries cooperatives. After reviewing various tests, we eventually select random effects model. The results, based on panel data between 2013 and 2018 year and 64 fisheries cooperatives, indicate that capital and area dummy variables have positive effects and employment has negative effect on the net income of regional and industrial fisheries cooperatives as predicted. However, debt are opposite with our predictions. Specifically, it turns out that debt has positive effect on the net income of regional and industrial fisheries cooperatives although it has been increased. Additionally, this paper shows that the member of confreres does not show any significant effect on the net income of regional and industrial fisheries cooperatives in South Korea. This study is significant in that it analyzes the major factors influencing changes in the net income that have not been conducted recently for the fisheries cooperatives by region and industry.

We simulated and compared present and future ocean circulation in the East China Sea using an East Asia Regional Ocean model. Mean climate states for 1990~1999 and 2030~2039 were used as surface conditions for simulations of present and future ocean circulation, which were derived from the simulations of three different global climate models, ECHAM5-MPI, GFDL-CM2.0 and MIROC3.2_hires, for the 20th century and those of 21st century as projected by the IPCC SRES A1B. East Asia Regional Ocean model simulated the detailed patterns of temperature, salinity and current fields under present and future climate conditions and their changes instead of the simple structures of global climate models. To some extent, there are consistent ocean circulation changes derived from the three pairs corresponding to the global climate model in so much as the temperature increases not only in winter but summer at both the surface and bottom and that temperature and salinity changes are prominent near the Chinese coast and in the Changjiang bank. However, the simulated circulations are different among each other depending on the prescribed atmospheric conditions not only under present climate but also with regard to future climate conditions. There is not a coincident tendency in ocean circulation changes between present and future simulations derived from the three pairs. This suggests that more simulations with different pairs are needed.

Purpose: Normal aging results in detectable changes in the brain structure and function. We evaluated the changes of regional cerebral glucose metabolism in the normal aging process with FDG PET. Materials and Methods: Brain PET images were obtained in 44 healthy volunteers (age range 20-69 'y'; M:F = 29:15) who had no history of neuropsychiatric disorders. On 6 representative transaxial images, ROIs were drawn in the cortical and subcortical areas. Regional FDG uptake was normalized using whole brain uptake to adjust for the injection dose and correct for nonspecific declines of glucose metabolism affecting all brain areas equally. Results: In the prefrontal, temporoparietal and primary sensorimotor cortex, the normalized FDG uptake (NFU) reached a peak in subjects in their 30s. The NFU in the prefrontal and primary sensorimotor cortex declined with age after 30s at a rate of 3.15%/decade and 1.93%/decade, respectively. However, the NFU in the temporoparietal cortex did not change significantly with age after 30s. The anterior (prefrontal) posterior (temporoparietal) gradient peaked in subjects in their 30s and declined with age thereafter at a rate of 2.35%/decade. The NFU in the caudate nucleus was decreased with age after 20s at a rate of 2.39%/decade. On the primary visual cortex, putamen, and thalamus, the NFU values did not change significantly throughout the ages covered. These patterns were not significantly different between right and left cerebral hemispheres. Of interest was that the NFU in the left cerebellar cortex was increased with age after 20s at a rate of 2.86%/decade. Conclusion: These data demonstrate regional variation of the age-related changes in the cerebral glucose metabolism, with the most prominent age-related decline of metabolism in the prefrontal cortex. The increase in the cerebellar metabolism with age might reflect a process of neuronal plasticity associated with aging.

본 연구는 경제개혁 이후 중국 연변조선족자치주내 조선족 인구감소의 메카니즘과 그 결과가 농촌지역에 미치는 영향 및 지역의 변화를 설명하기 위한 것이다. 중국의 시장경제체제의 도입, 호적제도의 약화 및 한 중 국교수립 이후 이동성향이 높아지고 통혼권과 거주지역이 확산되면서 조선족사회는 출산력수준의 급격한 저하와 젊은 층 및 여성 위주의 인구이동이 지속적으로 진행되었다. 이는 곧바로 농촌인구의 급격한 감소와 고령화로 이어져, 농업의 쇠퇴와 농촌지역의 조선족사회집단 해체, 기능약화, 민족교육의 위축 및 지도력 약화라는 결과를 초래하였다. 감소된 노동력을 보완하기 위한 농업경영상의 변화는 타지역 한족(漢族)농민들로 충당되었고 농업의 한족화 현상과 조선족에 비해 한족 농민들의 경제력 상승추세가 나타나고 있으며, 작물구성의 변화는 전통적 수전농업 체계에서 한전(旱田) 단작영 농체계로 특화되어 가는 경향이고, 노동력 효율적 분배가 가능한 상업적 작물이 인기가 높은 것으로 나타났다. 현재 조선족농업인구는 지속적으로 감소하는 추세이고 변화하고 있는 새로운 농업환경에 적절히 대응하지 못하는 문제들이 존재하며 이는 결국 조선족농촌마을이 소실될 위기에 놓여 있어 파격적인 정책지원 및 농촌개발정책의 수립이 중요하다.

The purpose of this study was to measure the changes of regional cerebral blood flow(rCBF) and blood pressure(BP) in rats, following the intravenous injection of Flos Sophora japonica L.(FSJ) water extract. The measurement was continually monitored by Laser-Doppler Flowmeter and pressure transducer in anaesthetized adult Sprague-Dawley rats for 2 hours to 2 hours and a half through the data acquisition system. FSJ increased the changes of rCBF in rat significantly. The rCBF of FSJ did not change by pretreated propranolol, atropine, L-NNA($N^G$-nitro-L-argininine) and indomethacin. But the rCBF of Flos Sophora japonica L. was increased by pretreated methylene blue. FSJ decreased the changes of BP, significantly. The BP of FSJ did not change by pretreated propranolol, atropine, L-NNA and indomethacin. But the BP FSJ was decreased by pretreated methylene blue. There results indicated that FSJ can increase the rCBF and decrease the BP, that is related to guanylyl cyclase activity.

Occurrence frequency of flood and drought tends to increase in last a few decades, leading to social and economic damage since the abnormality of climate changes is one of the causes for hydrologic facilities by exceedance its designed tolerance. Soil and Water Assessment Tool (SWAT) model was used in the study to estimate temporal variance of groundwater recharge and baseflow. It was limited to consider recession curve coefficients in SWAT model calibration process, thus the recession curve coefficient was estimated by the Baseflow Filter Program (BFLOW) before SWAT model calibration. Precipitation data were estimated for 2014 to 2100 using three models which are GFDL-ESM2G, IPSL-CM5A-LR, and MIROC-ESM with Representative Concentration Pathways (RCP) scenario. SWAT model was calibrated for the Soyang watershed with NSE of 0.83, and $R^2$ of 0.89. The percentage to precipitation of groundwater recharge and baseflow were 27.6% and 17.1% respectively in 2009. Streamflow, groundwater recharge, and baseflow were estimated to be increased with the estimated precipitation data. GFDL-ESM2g model provided the most large precipitation data in the 2025s, and IPSL-CM5A-LR provided the most large precipitation data in the 2055s and 2085s. Overall, groundwater recharge and baseflow displayed similar trend to the estimated precipitation data.

2010년 이후 한국에서는 주력업종의 침체가 지역경제 전반에 영향을 미쳐 지역적 위기로 번지는 현상들이 나타나고 있다. 본 연구는 조선과 자동차 산업의 쇠퇴로 위기에 놓인 군산시를 대상으로 지역의 산업구조와 제조업 경쟁력이 어떻게 변화하고 있는지 분석하는데 목적을 둔다. 분석결과, 군산시의 산업구조는 2010년 이후 변화의 속도가 빨라지고 다양성이 높아지고 있지만, 이는 주력산업을 중심으로 한 고용방출이 타 산업으로 흡수되었기 때문이며, 제조업 내에서는 주력산업의 위기를 대체할 수 있는 업종이 부재했다. 군산시 제조업 중 기반산업들의 특화도는 점차 약화되고 있고, 입지경쟁력 마저 약화되면서 제조업의 성장률 시차에 부정적인 영향을 미치고 있었다. 군산시가 제조업 위기에 대응할 수 있는 방향을 모색하기 위해서는 본 연구와 같이 지역의 산업구조적인 특성 변화를 면밀히 검토하는 일이 선행되어야 할 것이다.

This paper examines the empirical magnitude of local human capital spillovers in Korea during the 1980s and mid-1990s. Local human capital spillovers exists if plants in regions with a higher level of human capital can produce more given their own amount of input (Moretti 2004c). In particular, this paper explores an educational reform in South Korea which exogenously induced a large amount of variation in regional human capital levels. Using annually collected plant level data, I explore the effect of changes in the regional human capital levels induced by this reform on plant productivity in Korea. My results suggest that this effect is limited. I find a positive correlation between a regional level of human capital and plant productivity. However, after further addressing endogeneity using an instrumental variable, the effect of the overall regional human capital level on productivity decreases and becomes statistically insignificant.
