The Group has been established in 2016 for conducting research on international electric power networks in Asia from the viewpoint of technology, investment and legal framework. 2^(nd) report of the Group was published in June 2018, examining the profitability of an interconnectors between Japan and neighboring countries. The Group has calculated expected profit from operation of these interconnectors.The Group has categorized interconnector business into four models from the survey of preceding and current business on grids and interconnectors. To clarify profitability, expected internal rate of return(IRR) was calculated for each business model based on estimated investment cost for each route. When interconnector is dedicated to specific power plants or suppliers and electricity can be sold at Japan wholesale market at 2016-2017 price level, positive IRR levels are expected in case that Free on Board(FOB) price lower than 7 JPY/kWh. When the investment will be covered by electricity tariff by final consumers, tariff for consumers will just slightly increase by approximately 0.1 JPY/kWh.展开更多

Worldwide farming advancement is concerned with yield enhancement instead of a holistic natural source management for food safety. Nevertheless, knowledge regarding the achievement of agriculture systems subject to natural and conventional management in tropical and subtropical areas is insufficient. Why do several farmers record less profit than other farmers? Cost in agriculture activity influences the volume of profit gained by farmers. The number of respondents was 53. Data analysis was made using linear regression analysis to achieve the objective. The scatter diagram manifested a positive connection in cost and profit in agriculture activity from 2009 to 2013. For each cost increase in 2009-2012, the model forecasts a rise of returns for every year. The rate of profit earned by farmers every year shifts considerably in relation to the rate of cost in agriculture activity. This study recommends common accounting principles practices that exercise bookkeeping and managerial accounting to enhance farmstead management and profit. Future research may be conducted on the use of compost fertilizer in increasing agricultural income.展开更多

It analyzes the cost and profit to implement green marketing, both in a short term and in the long run. In a short term, the cost may increase. However, in the long run, the income will be higher than the cost. There're five reasons: reduced cost, expanding export by breaking down green barriers, establishing the enterprise's green image, being more competitive and avoiding green tax. Therefore, implementing green marketing is pivotal to the sustainable development of garment industry.展开更多
