  • Purpose: This study was on the economic feasibility of BIPV system, focused on comparison with construction cost of BAPV system depend on roof finishing materials, and to suggest basic data on the construction cost. Method: Construction cost of BAPV system was calculated, by selecting asphalt single, flat type roof tile, color steel plate, titanium zinc plate as roof finishing material of residential building and by sum up each cost for roof finishing construction and cost for 3kWp-volumed PV module installation. Also, the economic feasibility was analysed quantitatively by comparing the cost for BIPV system construction, installing same volumed PV module instead of roof finishing materials. Result: 1. By installing BIPV system instead of the roof finishing material, the cost of construction falls ; about 19% in case of the titanium zinc plate, which is the most expensive, and about 11% in case of the color steel plate. 2. Reducing amount of the construction cost gets larger because of installing BIPV module instead of the roof finishing material, as the construction cost for roof finishing material gets higher ; therefore, it is more economical than BAPV system in terms of whole cost of construction.

  • International remittances play a crucial role in the economic management of each country, especially in developing countries. Its functions are diverse, including procurement of foreign currency, serving as a cushion for the balance of payments and foreign exchange reserves by reducing the adverse external shocks, driving economic growth, easing the gap between the rich and the poor, and maintaining macroeconomic stability. However, previous studies on remittances have mainly focused on macro-and micro-economic aspects to analyze the determinants. Therefore, this study attempts to identify the determinants of remittances in 122 countries over the past 25 years from macroeconomic and educational aspects as well as institutional qualities. In addition, given the fact that almost all of the world's top 10 recipient countries in terms of GDP and total remittance size are developing countries, developed and developing countries are separated and analyzed for comparison, assuming that there may be a difference between the two groups. Results show that the coefficients of developed and developing countries are different in four areas: Control of Corruption (CC), Rule of Law (RL), Voice and Accountability (VA), and Regulatory Quality (RQ) among the six institutional variables of interest in this study. These results implicate that even the same institutions and policies should be applied and implemented differently depending on the circumstances of each country. In addition, as suggested by the World Bank, policymakers in all countries should double their policy efforts to lower the costs of remittance and improve access to the financial system for immigrants or dispatched workers to ensure a steady inflow of remittances.

  • The purpose of this study is to consider the socio-economic development and policy in each five-year economic development plan influences of urban households and to seek a plan of household stability and reasonable consumption expenditure on the aspect of Family economics. Data is based on the "Annual Report on the Family Income and Expenditure survey" of the National Bureau of Statistic Economic Planning Board, Republic of Korea and analyzed as follows: First, in analysis to the structure of consumption expenditure, the averaged percentage of each item to total consumption expenditure is estimated by each Economics Development Plan year. Second, in order to analyze the relative importance value of household consumption expenditure, priority correlation order is derived from comparison of characteristics of household consumption expenditures by multiple regression analysis. Third the patterns of consumption expenditure of salary and wage earner's households in all cities are estimated by the household consumption function, marginal propensity to consume, and income elasticity, according to socio-economic variable, and demographic variable. In the recent Korean economy, income level of household is increased and consumption expenditure level is largely increased because of the execution of economic development plan. But the improvement of income derives the increasment of the consumption needs and over-consumption trend is spread due to the import liberization. And above all, the reasonable household management and economic life are needed.

  • Less mature nuclear reactor technologies are characterized by a greater uncertainty due to insufficient detailed design information, operational data, cost information, etc., but the expected performance characteristics of less mature options are usually more attractive in comparison with more mature ones. The greater uncertainty is, the higher economic risks associated with the project realization will be. Within a comparative evaluation of less and more mature nuclear reactor technologies, it is necessary to apply economic risk measures to balance judgments regarding the economic performance of less and more mature options. Assessments of any risk metrics involve calculating different characteristics of probability distributions of associated economic performance indicators and applying the Monte-Carlo method. This paper considers the applicability of statistical risk measures for different economic performance indicators within a trial case study on a comparative evaluation of less and more mature unspecified LWRs. The presented case study demonstrates the main trends associated with the incorporation of economic risk metrics into a comparative evaluation of less and more mature nuclear reactor technologies.

  • This paper presents an improved method of calculating the penalty factors for economic load dispatch based on B-coefficient and AC load flow and their performance comparison. The algorithm for calculating B-coefficients by Meyer is improved and its performance is compared with that of AC load flow. The B-coefficient method is superior to the load flow method in its simplicity and computation speed. However accuracy of the B-coefficient method is not satisfactory when it is applied to the ill-conditioned systems where generators produce excessive reactive power.

  • 본 논문은 국가간 사회복지수준을 비교하는 기준으로서 경제수준과 사회수준 중 후자가 보다 적절한 기준임을 밝혀냈다. 또한 사회복지지출이 많은 나라들일수록 사회수준이 경제수준보다 높은 경향을 보였는데 이는 경제성장 위주의 정책보다는 사회 각 부문의 균형적 발전을 통한 보편적 삶의 질, 즉 사회수준 향상이 사회복지수준 향상에 중요한 요인임을 제시하는 결과였다. 한국의 사회복지수준은 우리의 경제, 사회수준을 고려한 기대수준보다 현저히 낮다는 기존의 사실을 다시 한번 확인하였다. 이러한 결과를 근거로 보편적 삶의 질과 빈곤층의 삶의 질 수준과의 격차를 해소하여 권리로서의 사회복지를 실현하는 것이 시급한 과제라는 것과 사회수준 자체의 향상을 통해 사회복지에 대한 국민적 관심을 증가시키고, 사회복지부문간 격차, 즉 사회보험과 공공부조와의 현격한 차이를 줄이는 정책이 필요하다는 점을 제시하였다.

  • This study examined the trend of healthcare status and compared the status of South Korea and other member of the Organization for Economic Cooperation and Development (OECD) using the OECD health statistics 2022. We used the OECD health statistics from 2022 and a position value for relative comparison (PARC) index to compare the five elements of the healthcare system. The study also used a Mann-Kendall test to analyze the trend of the PARC values from 2000 to the present year. The findings of the study indicate that many South Korea's PARC values were higher than the OECD median. But practicing physician in supply part and medical cost were lower than OECD median but the trend significantly increased. Medical accessibility part and quality of care part except primary care, and mental health had a high relative position but the trend did not increased significantly. After outbreak of coronavirus disease 2019, there were changes in medical accessibility. Health screening and vaccinations showed an overall decline in 2020 compared to 2019. These results suggest that policymakers need to take necessary steps for a sustainable healthcare system in the country.
