Estimation of future land cover based on climate change scenarios is an important factor in climate change impact assessment and adaptation policy. This study estimated future land cover considering Shared Socioeconomic Pathways (SSP) using Scenario Generators. Based on the storylines of SSP1-3, future population and estimated urban area were adopted for the transition matrix, which contains land cover change trends of each land cover class. In addition, limits of land cover change and proximity were applied as spatial data. According to the estimated land cover maps from SSP1-3 in 2030, 2050, and 2100, respectively, urban areas near a road were expanded, but agricultural areas and forests were gradually decreased. More drastic urban expansion was seen in SSP3 compared to SSP1 and SSP2. These trends are similar with previous research with regard to storyline, but the spatial results were different. Future land cover can be easily adjusted based on this approach, if econometric forecasts for each land cover class added. However, this requires determination of econometric forecasts for each land cover class.

무인항공기는 최근 10년간 빠르게 성장하고 있는 한편, 복잡하고 어려운 환경에서 적용가능하며, 높은 분해능을 가진 효율적인 탐사 기법의 필요성이 대두되고 있다. 이에 따라 기존의 탐사기술을 보완하고 대체할 수 있는 효율적인 탐사 방법으로 무인항공 탐사기술이 주목받고 있다. 특히나, 자력탐사기술은 무인항공기와 접목되어 빠르게 탐사 시장에서 자리를 잡아가고 있으며, 향후 활발하게 탐사분야에서 사용될 것이라고 기대된다. 국내 탐사시장에서 적절하게 활용되기 위해서는 최신 연구 동향에 대한 검토가 필요하며, 이를 위해 이 해설논문에서는 현재까지의 무인항공기반 자력탐사시스템 개발에 대한 연구동향들을 정리한 후, 향후과제들에 대해 검토하였다.

These days, corporate risk management has become a major concern in the corporate world. Companies in the global environment are exposed to diverse kinds of risks that are affecting the decisions of investors and other stakeholders. Therefore, companies are expected to not only identify and manage risks but also voluntarily report the same to the stakeholders. Increasingly, standard setters and regulators are requiring firms to disclose such information. On the contrary, there also exists a perception that risk reporting can create a negative impression among the stakeholders about the future of the company. In line with such growing dilemma for risk disclosures, the issue of corporate risk reporting (CRR) has been receiving immense emphasis from the accounting academicians. The main objective of this article is to conduct a comprehensive literature review on corporate risk disclosures. In order to fulfill this objective, at first, a summary of the relevant available literature is presented to identify the current regulations on risk reporting, existing trends of CRR research and theories applied in research. Then, through analysis, several research avenues are identified. It is expected that if these dimensions are explored by the future researchers, a better and broader understanding of the risk reporting practices can be achieved.

본 연구는 가상화폐의 국내 연구동향 고찰을 통하여 향후 가상화폐관련 연구에 시사점을 제공하고자 하였다. 연구결과 가상화폐 국내 연구는 고찰 한바와 같이 2018년도부터 본격화 하고 있으나 학술지논문은 14개, 학위논문 14개 총 30여개 정도로 아직 연구가 미진한 편이다. 세부 주제별로 보면 상대적으로 법적, 과세, 시장 측면은 연구는 수용의도 측면의 연구보다는 많은 편이다. 본 연구에서 연구주제로 구분한 법적, 과세, 범죄, 시장, 수용의도 측면 연구 중 상대적으로 수용의도 측면의 연구가 학술적 가치를 지니고 있을 것이라고 보면 향후 가상화폐 관련 연구는 수용의도 등 좀 더 학술적인 주제가 활발히 진행 될 필요가 있다고 사료된다.

Following the global air-traffic market growth outlook, urgency of technical development is needed in responding to changes in the international air-traffic management paradigm and to prepare technology securing and spreading strategies, which are consistent with systematic aviation weather service policies and evolution direction. Although air traffic has decreased significantly due to COVID-19, normalcy is expected from 2024, as announced by IATA. According to the future air transportation market outlook and development trends of related technologies, Korea has established and implementing the next-generation air transportation system construction plan(NARAE) to secure international competitiveness and leadership in the future. Therefore, this paper describes the technical, economic background and requirements of numerical model-based aviation weather R&D projects for successful implementation of domestic NARAE plans and providing aviation safety and air traffic service efficiency. Furthermore, we proposed numerical-model-based technology development content, strategies and detailed load-map.

In this study, we collected and analyzed domestic and international studies related to watersheds in the forest sector. Keyword co-occurrence analysis was conducted using the VOSviewer program to identify the research areas of domestic and international studies and the network structure to compare research trends. As a result, the number of research articles in international watershed-related studies showed an overall increasing trend, and the research areas were diverse and located close to each other, indicating that many convergence studies were conducted. On the other hand, the number of papers in domestic watershed-related studies seems to have stagnated overall from the past to the present, and the research areas are mainly focused on forest disasters and hydrology, with limited interdisciplinary convergence studies. In addition, in both domestic and international studies, watersheds are currently mentioned as research sites rather than management or analysis units in the forest sector. It is important to actively promote interdisciplinary research in Korea to provide a scientific and balanced basis for watershed-level forest management planning.

Reading and foreseeing fashion trends is crucial and difficult in the fashion industry due to accelerated and diversified changes in fashion trends. We use network analysis to investigate fashion trends from 2004 to 2013 in order to find the inter-relevance among fashion trends. We extracted words from fashion trend info for women's wear provided by Samsung Design Net, created a 2-mode network of seasons and trend languages, and visualized this network using NodeXl program. Fashion trends repeated a unique pattern during the period. In the first half (2004-2008), retro modern, feminine modern, and ecological modern were dominant trends in consecutive order. The years 2009-2013 witnessed distinctive fashion trends in S/S seasons and in F/W seasons. 11F/W, 12F/W and 13F/W seasons were characterized by artistic creative style. From 2010, natural style dominated S/S seasons. 10S/S and 12S/S seasons were distinguished as a calm natural style that reflected a peaceful and simple life. In 11S/S and 13S/S seasons, soft natural style emerged as a sign of increased importance of inner spirit and natural energy. A seasonal reappearance of trends was observed every two years in S/S seasons that enabled the prediction that 14S/S will see another version of natural style. A macroscopic trend for the last 10 years was represented by the keywords 'modern' and 'natural'. 'Modern' involved the past styles such as 60's, Baroque and the origin of human life. 'Natural' was connected with design elements such as material, silhouette and color. Managerial implications and future study directions are discussed based on the results.
