  • A large amount of time and cost is consumed due to congestions caused by an increasing number of cars which results in a lot of emissions. To overcome these problems, a new electric vertical takeoff and landing (eVTOL) aircraft is being considered. Since vertical take off and landing without a separate runway is realized and electricity is used as a power source, it could solve the saturated ground traffic congestions without emissions. In this paper, the initial sizing was performed based on the Nexus 6HX of Belltextron which is a tilt-ducted fan type. In this study, the electric propulsion system that only uses battery was implemented instead of current Nexus 6HX hybrid electric propulsion. Aerodynamic analyses were performed using OpenVSP and XFLR5. Power-to-weight ratio, wing loading, estimated weight were calculated with these analyses.

  • Government expenditure on education has attracted much attention because it plays an important role in the economic development. The question is whether government expenditure on education has a positive or negative impact on the economic growth and vice versa. This study aims to provide reliable estimates of the relationship between government expenditure on education and economic growth with empirical evidence in Vietnam for the period 2006-2019. The data was taken from the official statistics of the General Statistics Office of Vietnam. The authors have used the VAR model and Granger causal model to determine the relationship between government expenditure on education and the economic growth. Research results show that there is a two-way nexus between the economic growth and government spending on education with a lag of about two years. From the results obtained from this research, the authors have made some policy suggestions for the Vietnamese government as how to increase investment for education. If there is a one-way causal relationship between expenditure on education and the economic growth, the government can use spending as a growth factor. However, if there is a bi-directional relationship between the government expenditure on education and the GDP growth, the government needs to ensure that resources are appropriately managed and allocated effectively to promote growth.

  • This study investigates the nexus among the South Asian economies. Effects of shocks in the equity market of one country on the equity market of the other country are examined. For empirical analysis, the time series monthly data is used for the period from February 2013 to August 2019. The study focuses on the four larger economies of the region, namely, India, Bangladesh, Pakistan, and Sri Lanka. To investigate for asymmetric effects of positive and negative shocks, EGARCH model is used. The findings show the mix nature of the spillovers between the various pairs of countries. The equity market of Pakistan has two-way spillover effects with the equity market of Bangladesh, but has no association with the equity markets of India and Sri Lanka. The volatility in the equity market of India significantly influences the volatility of the financial markets of Bangladesh and Sri Lanka. Similarly, the capital market of Sri Lanka has a negative association with the equity market of India as well as Bangladesh, but does not affect the equity market of any other country. These findings validate the argument in the literature that geographic location influences the nexus among equity markets. The findings are important for policy-makers and investors.

  • The current study examines the relationship between inventory management efficiency and financial performance in Saudi Arabian companies. The study collected data from the companies listed on Tadawul (a Saudi Arabian stock exchange) during the period starting from 2016 and ending in 2020. The study uses pooled regression model by incorporating Return on Assets (ROA) and Inventory Turnover Ratio (ITR) as a performance measurement variable and inventory conversion period as an inventory management variable to report the results. The results show a positive and significant association between inventory management and firms' financial growth measured in terms of Return on Assets (ROA). Further, the study reports a positive and significant association between the inventory conversion period and inventory turnover (ITR). This shows that managing inventory efficiently shall positively impact the firm's performance. The other variables, such as debt ratio and gross profit, are positively related to ROA and negatively correlated with ITR. The firm growth is positively associated with both the dependent variables. The results suggest that the management of inventory in Saudi Arabian firms is efficient. Further, the firm size is positively associated with ROA and ITR. This shows a nexus between inventory management efficiency and firms' financial growth in Saudi Arabian companies.

  • The current study examines the nexus between the capital structure (debt-equity) and firm value (Tobin's Q) by including profitability (alternatively Return on Assets (ROA) and Return on Equity (ROE)) as a moderator in the companies of Saudi Arabia. The study sample consists of 102 companies listed on Tadawul (the Saudi Arabian stock exchange) from different sectors of Saudi Arabia during the period 2013 to 2020. The study estimates pooled regression, panel regression with fixed and random effects, and dynamic panel regression models to report the results. The study results report that there is a negative and significant association between capital structure and firm value in model 1, while in models 2 and 3 there is a more negative and significant impact between the two study variables compared to model 1 after the inclusion of interaction variable, i.e. profitability in terms of ROA and ROE. The comparative result shows that the companies of Saudi Arabia hold more debt in their capital structure mix, hence evidencing a decrease in the firm value. The reported results also show that models 2 and 3 are better in explaining the impact of capital structure on firm value due to the interaction of profitability compared to model 1.

  • This study is aimed at using the grasped problems of protected areas in Korea as the basic data for management planning and system improvement of protected areas by grasping realistic problems through the interview with the persons in charge on the basis of general problems of domestic protected areas. To this end, this study deducted major problems in urgent need of improvement, and improvement direction through the survey of the persons in charge of protected areas. This study result is as follows: The major problems, which should be preferentially improved, were found to be shortages of management infrastructure, cooperation between interested parties, and threat factors in protected areas, etc. Such problems are interconnected with each other, thus coming up complexly; therefore, it's necessary to make a comprehensive approach to the problems after confirming the causal relationship of the identified problems. In addition, for the purpose of effective management of a protected area, it's necessary to implement priority management of major problems through different management intensity from the planning phase. Also, it's important to enhance the effectiveness of planning by considering a possible potential threat factor in the outside of protected areas, and referring to the contents of the development plan for the relevant area in time of management planning. Lastly, there is the need for systematic improvement of an institution through thorough status review of the actual state of management planning fulfillment in order to increase the effectiveness of planning in a follow-up study hereafter.

  • An agrivoltaic system (AVS) is a combined system that generates power through photovoltaic panels (PVPs) installed above a field where a crop is cultivated. Although soil moisture is an important limiting factor for open-field crop production, particularly during spring season in Korea, it is not well considered in the utilization of AVS. Indeed, the application of water-energy-food nexus on the AVS should be necessary. In this study, the changes of soil moisture and temperature under the AVS was investigated in fallow paddy field during spring season. The AVS that has partial shading condition by PV panels was decreased soil temperature and increased soil moisture compared to open-field. Furthermore, the maximum of the change in soil moisture to the change in soil temperature had a negative correlation both on open-field and AVS under wet condition. It represents that the micro-climate under the AVS is in energy-limited condition. The open-field of relatively high soil temperature was in water-limited condition. The different behavior of soil moisture on the AVS should be considered for the sustainable agricultural system as related to water-energy-food nexus.
