Purpose - This article analyzes the impact of macroeconomic variables of the United States, China, and Korea on KOSPI and VKOSPI, in that United States and China have a great influence on Korea, having an export-driven economy. Design/methodology/approach - The influence of US, China, and Korea interest rates, industrial production index, consumer price index, US employment index, Chinese real estate index, and Korea's foreign exchange reserves on KOSPI and VKOSPI is analyzed on monthly basis from Jan 2012 to Aug 2023, using multifactor model. Findings - The KOSPI showed a positive relationship with the U.S. industrial production index and Korea's foreign exchange reserves, and a negative relationship with the U.S. employment index and Chinese real estate index. The VKOSPI showed a positive relationship with the Chinese consumer price index, and a negative relationship with the U.S. interest rates, and Korean foreign exchange reserves. Next, dividing the analysis into two periods with the Covid crisis and the analysis by country, the impact of US macroeconomic variables on KOSPI was greater than Chinese ones and the impact of Chinese macroeconomic variables on VKOSPI was greater than US ones. The result of the forward predictive failure test confirmed that it was appropriate to divide the period into two periods with economic event, the Covid Crisis. After the Covid crisis, the impact of macroeconomic variables on KOSPI and VKOSPI increased. This reflects the financial market co-movements due to governments' policy coordination and central bank liquidity supply to overcome the crisis in the pandemic situation. Research implications or Originality - This study is meaningful in that it analyzed the effects of macroeconomic variables on KOSPI and VKOSPI simultaneously. In addition, the leverage effect can also be confirmed through the relationship between macroeconomic variables and KOSPI and VKOSPI. This article examined the fundamental changes in the Korean and global financial markets following the shock of Corona by applying this research model before and after Covid crisis.

최근 들어서 본격화된 '경제의 세계화'는 세계경제공간조직에 심대한 변화를 야기하였다. 본 연구에서는 세계화와 지방화의 개념, 태평양지역에서 나타난 경제공간조직 변화의 흐름, 그리고 경제공간조직 변화와 관련된 주요 과정을 검토하였다. '영역과 영역사이의 상호의존성 증대'로 인식되는 세계화의 진척은 특히 태평양 지역의 경제공간조직에 큰 변화를 가져왔으며, 이는 크게 지역내 교역과 해외직접투자의 증가, 신산업지구의 발전, 국경지대의 성장삼각지대의 등장 등으로 요약될 수 있다. 이러한 경제공간조직의 변화를 야기하는 요인으로는 세계적 차원에서 이루어지는 공간분업과 상품체인, 신흥 공업국의 산업구조재편, 생산조직 및 산업의 네트워크 형성 등을 꼽을 수 있다. 앞으로 세계화/지방화로 인한 변화가 가져오는 부정적 효과를 최소화하고 지속가능한 발전을 하기 위해서는 '협력적 네트워크 전략'을 추진하는 것이 필요하다.

In this paper, the nature-based tourism is described as one of the tools to achieve sustainable development in small islands. The study was carried out at Ayer, Bidadari and Onrust Islands of Kepulauan Seribu chains at Jakarta Bay, Indonesia. While the historical records show that previous uses of such islands have started at sixteen century, tourism uses was started at the beginning of 1970s. Among nature-based tourism destination in Kepulauan Seribu chains, these islands are the famous destinations and received a lot of tourists. Tourism growth at these islands has stimulated development of numerous tourism facilities and infrastructure to meet visitor satisfaction. It is observed in this study that island's site-plan destination design has contributed to the successful and sustainability of tourism in small island. The key success lies on the successful integration and implementation of three substantial perspectives into practices, namely economic, ecosystem and social perspectives. First, in order to enhance economic benefits, a site-plan design allowing floating cottages establishment to extent room availability, to build strong images as tropical paradise islands, and to enhance tourist satisfaction with the objectives of improving income and sustaining tourist loyalty to the destination. This design is also reducing land risk from tourism impact and it becomes the significant key of second perspective, the ecosystem perspective. Moreover, the ecosystem perspective has been implemented through native vegetation preservation that led island's wildlife conservation and became potential tourism attraction. The design also develops effective mechanism to manage and regulate visitor flows by establishing visitor track corridors. In implementation, such corridor plays an important role to reduce tourist density in single places and therefore become instrument to reduce severe visitor impact to wildlife, vegetation and heritages of islands. Third, the social aspect of development allowing heritages to conserve and furthermore serve numerous benefits for education, socio-political, culture, and historical studies. Through this study, it is clear that the success of these islands to continuous tourism growth lies on the island's vision to integrate economic, ecosystem and social perspectives on tourism development.

Purpose - "Trade Facilitation" aims the easier flow of trade across borders, driven not only by effective customs administration, the efficiency of appropriate authorities, but also by telecommunications, the quality of infrastructures and competent logistics. Facilitating trade will help lower trade development costs as well as improve economic development and enhance economic benefits for emerging economies at a time when imports and exports are sent in and out across borders several times in the form of intermediate and final products. Not only that, globalization is being accelerated, which in turn increases competitiveness and this makes logistics one of the key factors when it comes to international trade. Highly efficient logistics services promote product movement, ensure product safety and delivery speed, and reduce trade costs between countries. The purpose of this study is, by using the LPI indices based on gravity model estimates, to analyze the impact of each LPI component on trade with the 20 biggest exporting countries of Northeast Asian countries-Korea, Japan, and China-which account for 19.05% of global exports. Design/methodology - Also, this study statistically analyzes the impact of trade on Northeast Asian countries' top 20 exporting countries, using the LPI indices relevant to Trade Facilitation based on the gravity model estimates. Findings - As a result, it was turned out that the distance, GDP, and the LPI components have relevant impact on the trade exports of all three countries but demonstrated little relation to the demographic perspective. Originality/value - The study also found we can increase the trade volume by improving three countries' trade partners' LPI indices since Korea, Japan, and China share most of their 20 biggest trade partners.

Background: Invasive alien plant species (IAP) significantly threaten Nepal's protected areas and local communities. Understanding their distribution, impact, management, and utilization is essential for developing effective management strategies and sustainable utilization practices. The systematic literature review of publications from 2010 to 2023. The search was conducted through the database Nepal Journal online database (NepJOL) and Google Scholar, yielding an initial pool of 4,304 publication. After applying inclusion and exclusion criteria; we meticulously reviewed 43 articles for data extraction. Results: Seventeen IAP are found in protected area, Nepal with the highest prevalence observed in Koshi Tappu Wildlife Reserve, followed by Chitwan and Sukhlaphanta National Park. The most problematic species in terrestrial ecosystems are Mikania micrantha, Lantana camara, and Chromolaena odorata. The grassland ecosystems of wildlife habitats, primarily in the Terai and Siwalik regions, are the most invaded. Various management approaches are employed to mitigate the spread and impact of IAP, including mechanical methods such as uprooting, burning, and cutting. However, these methods are costly, and context-specific interventions are needed. The study also explores the potential use of IAP for economic, ecological, or cultural purposes, such as medicinal properties, energy production potential, and economic viability. Local communities utilize these plants for animal bedding, mulching, green manure, briquette, and charcoal production. Conclusions: Applying silvicultural practices alongside mechanical management is recommended to maintain a healthy terrestrial ecosystem and utilize the removed biomass for valuable products, thereby reducing removal costs and increasing income sources, potentially benefitting both local communities and wildlife in protected areas.

Since the first oil embargo (1973), there have been developed many different types of energy-economy interaction models based upon various aspects of energy impact mechanism. We will propose to develop an integrated energy-economy interaction analysis system for less developed countries' energy policy analysis, especially for investment analysis toward constructing energy-saving industry infrastructure ; which is based on the motivation of combined energy models by John P. Weyant. This modeling system can cover the economic growth, inter-industry transactions including production features, and process analysis of energy sector in the total network scheme of general equilibrium, so that it can give many political implications as well as the modeling concept to be used for analyzing various political issues and making decisions related to national energy environment.

The objective of this study is to obtain a better understanding of the current rice production condition in Myanmar through efficiency analysis, especially, to examine the impact of farm mechanization on Myanmar rice production efficiency. For representation of efficiency and the determinants, this paper uses both the data envelopment analysis (DEA) and the stochastic frontier approach (SFA) with variable returns to scale on Myanmar rice production. The efficiency of the rice production was estimated and subsequently the determinants factors were investigated based on the estimated efficiency level of these sample farmers. The empirical evidence finds that farm mechanical tools significantly improve the Myanmar rice production efficiency.

This paper investigates short selling behavior, particularly by foreign investors, during event days of non-normal times on an intraday basis in the Korean stock market around the global financial crisis. Although, in the several subsamples, we cannot exclude the predatory short-selling possibility, we did not find any conclusive evidence of abusive short selling behaviors in the overall intraday trading activities. While foreign investors demonstrate higher levels of participation in short-sale trading, their impact on price declines is not as pronounced compared to the effects of pure selling. Following the lift of the short-sale ban, foreign investors appear to engage in long selling trading more frequently, and their influence on price changes primarily stems from long selling rather than short selling compared to the past.
