Massive migration is underway in rapidly urbanizing Guangzhou, the south gate of P. R. China. Over half the migrants choose to rent in "villages-in-the-city" in the downtown area because of the low-cost and prime location. The overpopulation and resulting poor environment and high crime-rate turn villages-in-the-city into de facto ghettos. As a result, these ghettos are undergoing a manner of demolition-development, leaving migrants' housing needs unmet. A private-sector initiative-the Tulou Commune-intends to address this considerable market potential. Targeting low-income groups, the Tulou Commune creates a socio-spatially exclusionary enclave. This paper analyzes the Tulou Commune and the implications if more low-income migrants shifting from village-in-the-city (excluded ghetto) to Tulou Commune (exclusionary enclave). This study argues that the intervention of the private sector causes the demographic, social, and spatial similarities and differences of the two living arrangements. Socioeconomic and institutional factors also affect the initiative. This study also provides more empirical evidence in the field of low-cost housing and socio-spatial development in transitional Chinese cities. As the first project of its kind, the analysis of the case can suggest how to improve strategies for accommodating migrants in the future.

공공보건정책사업에 대한 투자는 국민들의 건강수준을 향상시켜 미래의 의료비 절감효과가 나타날 것이며 질병부담 감소로 인한 생산성 손실이 감소할 것이며, 이러한 공공보건정책사업에 의한 건강증진효과는 경제성장을 촉발시키는 원동력이 될 것으로 사료된다. 본 논문에서는 공공보건정책사업의 투자효과를, 사업시행의 결과로 국민들의 질병으로 인한 사회경제적 비용이 감소했는지의 여부와 그 정도로 측정했으며, 특히 구축된 시계열 자료를 토대로 미시적 분석을 수행하기 위해, 질병으로 인한 사회경제적 비용규모가 가장 큰 5대 질환군 및 각 연령대별 인구집단을 대상으로 시행된 공공보건정책사업의 건강증진효과와 이들 효과가 경제성장에 미친 영향을 분석하였다. 분석결과를 요약하면, 질환별로는 호흡기계, 소화기계, 순환기계 및 감염성 질환 등에서 정책효과가 유의했고, 연령대별로는 0~9세, 10~19세, 40~49세, 50~59세, 60~69세 및 70세 이상 연령대에서 유의한 효과를 보였다. 아울러 이들 질병으로 인한 사회경제적 비용의 절감은 실질국내총생산의 증가에 통계적으로 유의하게 영향을 미쳤음을 알 수 있었다.

Ever since Benoit's(1973, 1978) study, the relationship between defense spending and economic growth has been the subject of extensive empirical works. While a number of studies have reported that higher defense expenditure stimulate economic growth, many other studies have reported that an increase in military burden may hinder economic growth. To the extent that countries differ substantially in socioeconomic structures, the effects of defense spending cannot be generalized across countries. In this paper, Granger causality tests are performed between Korean defense expenditure and economic growth, consumption, investment, inflation and unemployment rate during the period from 1970 to 2002. The results show that Korean defense expenditure did not affect economic growth and unemployment rate. However, Korean defense expenditure caused consumption and inflation to decrease and investment to increase. On the other hand Korean defense expenditure was not Granger-caused by economic growth, consumption, investment, inflation and unemployment rate. In conclusion, the opportunity cost of Korean defense expenditure seemed to be relatively moderate considering Korean security environment. Even if it was not statistically significant, Korean defense burden at least did not bother economic growth.

The traffic accidents in Korea have been increasing every year due to various reasons and simultaneously causing socioeconomic cost at the national level. This study has analyzed the correlation between meteorological factors and the traffic accidents in Seoul during 2013. Especially, we have selected season, rain and temperature among the meteorological factors to identify their significance with the traffic accidents. In addition, analysis of variance, t-test and a multiple regression technique is applied. Major findings from the analyses are discussed at the district point of view, including the different effect of weather condition and the interaction effect of rain and temperature in winter. The results of this study would be useful for developing management strategies to reduce car crashes and injury severity in Seoul.

Objectives : The purposes of this study is to estimate the cost of cancer care after its diagnosis and to identify factors that can influence the cost of cancer care. Methods : The study subjects were patients with an initial diagnosis one of four selected tumors and had their first two-years of cancer care at a national cancer center. The data were obtained from medical records and patient surveys. We classified cancer care costs into medical and nonmedical costs, and each cost was analyzed for burden type, medical service, and cancer stage according to cancer types. Factors affecting cancer care costs for the initial phase included demographic variables, socioeconomic status and clinical variables. Results : Cancer care costs for the initial year following diagnosis were higher than the costs for the following successive year after diagnosis. Lung cancer (25,648,000 won) had higher costs than the other three cancer types. Of the total costs, patent burden was more than 50% and medical costs accounted for more than 60%. Inpatient costs accounted for more than 60% of the medical costs for stomach and liver cancer in the initial phase. Care for latestage cancer was more expensive than care for early-stage cancer. Nonmedical costs were estimated to be between 4,500,000 to 6,000,000 won with expenses for the caregiver being the highest. The factors affecting cancer care costs were treatment type and cancer stage. Conclusions : The cancer care costs after diagnosis are substantial and vary by cancer site, cancer stage and treatment type. It is useful for policy makers and researchers to identify tumor-specific medical and nonmedical costs. The effort to reduce cancer costs and early detection for cancer can reduce the burden to society and improve quality of life for the cancer patients.

교량구조물은 사회물류흐름에 필요한 중요한 역할을 하는 사회간접시설물로 공용수명이 다하거나 지진, 폭풍 등의 자연재해에 따라 구조물의 손상이 발생할 경우 기존 교량을 철거하고 재가설 하여야 한다. 공용중인 교량을 재가설할 경우, 차량의 우회, 교통체증에 따른 사용자비용과 공사기간동안의 소음, 분진 등에 따른 사회비용이 발생하게 된다. 하지만 교량의 재가설에 따른 사용자비용과 사회비용은 교량건설시 고려되지 않고, 이를 평가하는 방법 또한 모호하므로 이를 적용한 교량형식이 선정되지 못하고 있다. 따라서 본 연구에서는 교량의 재가설시 발생되는 사회적 간접비용, 즉 사용자의 사회적, 경제적 가치를 파악하여 교량 재가설에 따른 사용자비용의 평가방법을 제안하고 이를 평가하였다. 사용자비용의 평가 시 교량의 일교통량, 첨두시간, 우회거리, 우회시간 등을 포함한 교통정보와 사회적 물동량이 고려되었으며, 차량운행비용과 교량 재가설에 따른 시간지연비용 또한 고려되었다.

Background: The rise in national health care costs has emerged as a global problem given the ever-aging population and rapid development of medical technology. The utilization of interventional pain management has, similarly, shown a continued rise worldwide. This study evaluates the differences in the medical costs in the field of interventional pain treatment (IPT) between two countries: Korea and Japan. Methods: Korean medical insurance costs for 2019 related to pain management focused on IPT were compared to those of Japan. Purchasing power parity (PPP) was used to adjust the exchange rate differences and to compare prices in consideration of the respective societies' economic power. Results: The cost of trigger point injections in Japan was 1.06 times higher than that of Korea, whereas the perineural and intraarticular injection prices were lower in Japan. The cost of epidural blocks was higher in Japan compared to Korea in both cervical/thoracic and lumbar regions. As for blocks of peripheral branches of spinal nerves, the cost of scapular nerve blocks in Japan was lower than that in Korea, given a PPP ratio 0.09. For nerve blocks in which fluoroscopy guidance is mandatory, the costs of epidurography in Japan were greater than those in Korea, given a PPP ratio 1.04. Conclusions: This is the first comparative study focusing on the medical costs related to IPT between Korea and Japan, which reveals that the costs differed along various categories. Further comparisons reflecting more diverse countries and socio-economic aspects will be required.

Vulnerability due to climate change depends on the concentration of carbon dioxide emissions over several upcoming decades. The objective of this study is to estimate the concentration of greenhouse gases and air pollutants in 2100, while also accounting for expected socio-economic changes in Korea. First, we intend to prepare scenarios for possible socioeconomic changes in Korea: business as usual (BAU), high growth and low growth. Secondly, we aim to predict services demands in residential?commercial sector, transportation sector, industrial sector for each scenarios. Finally, the emissions of LLGHG and SLCP will be estimated on the basis of the predicted service demands. The study results project that in Korea, LLGHG emissions will be approximately $660Mt\;CO_2\;eq$. and SLCP emissions will be approximately 3.81 Mt, -including black carbon (BC) by 2100. The transportation and industrial sectors are the major source for LLGHG emissions, and the residential and commercial sector serve as the SLCP source. Later, additional studies on the cost and benefit of mitigation should be carried out by comparing the reduced use of materials that cause climate change as a result of reduction policies and the socioeconomic cost.
