We investigate how reforestation contributed to stabilization of riverine water levels in South Korea. For the purpose, we estimate an equation capturing dynamic relationships among rainfall, upstream-area tree stock, and downstream water levels in three river systems of Hongcheon, Mangyeong, and Hyeongsan, using daily observations of precipitation and water levels for the period from 1985 to 2005. Simulation based on estimation results shows that increase in the tree stock in a river basin leads to a significantly suppressed peaking in riverine water levels in response to an abrupt and concentrated rain in the upstream area. For instance, an hour-long concentration of 100mm rain results in 0.7m rise in water level if the volume of growing stock is 1 million m³, whereas the rise in water level stays below 0.27m with 5 million m³ in the growing-stock volume.

Text data mining ('big data methods') is one of the most widely used approaches during the COVID-19 pandemic. In particular, text data mining on Scopus databases or Web of Science (WoS). Text data mining is widely used to collect literature for later bibliometric analysis, and in the end, it becomes a literature review article. Therefore, in this article, we reveal the trend of publication of literature reviews in Scopus journals from Indonesia, Japan, South Korea, Vietnam, Singapore, and Malaysia. This article describes two essential parts, namely 1) a comparison of international publication trends and subject area of literature review publications, and 2) a comparison of Top 5 for Authors, Affiliation, Source Title, and Collaboration Country.

기후변화 대응과 탄소중립 사회로의 이행과정에서 중요한 역할을 담당한 산림이 제공하는 혜택의 사회적 가치는 점증해 왔다. 경제적·공익적 가치를 매개로 산림 부문 체계는 산주·임업인의 범주를 넘어 전체로서의 사회와 상호작용한다. 따라서 전체 사회의 관점에서 산림과 산림정책에 대한 공공 인식과 선호를 파악하는 것은 앞으로 산림정책 방향 설정에 있어서 중요하다. 이를 위해 본 연구는 산림청에서 설문조사 전문기관을 통해 1991년부터 2023년까지 7차례에 걸쳐 수행한 '산림에 관한 국민의식조사' 결과를 바탕으로 지난 32년간 의식변화를 시계열적 비교를 통해 분석하였다. 연구 결과 전반적인 산림정책에 대한 국민의 만족도는 높아졌으며, 산림녹화, 숲길·숲교육, 산림휴양시설 설치·운영 순으로 만족도가 높았고, 산지이용·관리, 산림재해 예방, 국제산림협력 순으로 만족도가 다소 낮은 것으로 나타났다. 또한, 국민은 숲가꾸기, 임도, 해외조림 정책은 지금보다 더 확대가 필요한 것으로 판단했다.

We are based on the results of this study, the policy measures for improving the efficiency of supply & demand policy of public cremation facilities in six metropolitan cities in the whole nation could be suggested as follows. First, when the utilization rate of public cremation facilities by citizents out of the jurisdiction area was lower, the overall demand for cremation was high. Therefore, the supply & demand policy of public cremation facilities should be carried forward by preferentially focusing on Busan Metropolitan City(4.1%) and Daegu Metropolitan City(17.9%) with low utilization rate by citizens out of the jurisdiction area. Second, the utilization variance of public cremation facilities in the whole six metropolitan cities in the whole nation, was insignificant(1.4%). Therefore, for the efficiency of supply & demand policy of cremation facilities in those six metropolitan cities, the customized-policies considering the characteristics of each metropolitan city should be carried forward in priority. Third, on the basis of 2018, the population size of those six metropolitan cities in the whole nation is from minimum 1.15million to maximum 3.39million as a large city, and relatively, they are facing many difficulties in the expansion for supply & demand of cremation facilities. Therefore, for the smooth construction of cremation facilities, it would be necessary to enforce policies that could disperse the demand for cremation through the joint construction of cremation facilities with other local governments close to each metropolitan city.

This study seeks to provide implications for domestic-related policies through exploratory analysis research to support AI-based policy decision-making. The following should be considered when establishing an AI-based decision-making model in Korea. First, we need to understand the impact that the use of AI will have on policy and the service sector. The positive and negative impacts of AI use need to be better understood, guided by a public value perspective, and take into account the existence of different levels of governance and interests across public policy and service sectors. Second, reliability is essential for implementing innovative AI systems. In most organizations today, comprehensive AI model frameworks to enable and operationalize trust, accountability, and transparency are often insufficient or absent, with limited access to effective guidance, key practices, or government regulations. Third, the AI system is accountable. The OECD AI Principles set out five value-based principles for responsible management of trustworthy AI: inclusive growth, sustainable development and wellbeing, human-centered values and fairness values and fairness, transparency and explainability, robustness, security and safety, and accountability. Based on this, we need to build an AI-based decision-making system in Korea, and efforts should be made to build a system that can support policies by reflecting this. The limiting factor of this study is that it is an exploratory study of existing research data, and we would like to suggest future research plans by collecting opinions from experts in related fields. The expected effect of this study is analytical research on artificial intelligence-based decision-making systems, which will contribute to policy establishment and research in related fields.

Passing 26 years from 1970 when the first satellite was launched into the orbit, Japan developed and successfully launched H-II from Tanegashima Space Center in 1994. During those period, Japanese space policy has experienced a big shake from independent development to technology import from the US, and back again to independent development. In general, the H-II rocket which was manufactured by 100% domestic technology, brings Japan from the old era (experimental stage) to the new era (practical use stage). Fundamental Policy of Japan's Space Activities, which decides such policy as mentioned, was revised in January, 1996 this year after an interval of 7 years. This revised outline confirms the result of Japanese space technology until present and identifies the future direction and framework of her space activities for a period of coming ten years on the basis of a ong-term perspective towards the 21st century. However, when comparing with the last Fundamental Policy in 1989, there seems no big change in it, and a long-term perspective is also not seen there. The description varies on some important points in international space law, like international cooperation, protection of environment, commercial use, etc. In addition, the immaturity as well as the necessity of broader discussion are felt because neither this Fundamental Policy nor The National Defense Program Outline treated any national and international security matters concerning outer space. Considering the present time when Japan enters into the practical use of outer space, such as application, commercial use and launching service, etc, it is doubtful whether new Fundamental Policy was properly planned or not. It seems necessary to use several measures by which the public opinion, opinions from industry and debate on the security are reflected in the policy making.

본 연구의 목적은 한국노년학회의 40년간 주요 학술활동을 한국노인정책의 변화와 세계노년학 노인의학회(IAGG)의 학술동향에 맞춰 분석해 보고, 향후 노년학회의 학술발전 방향을 제시하는 것이다. 연구방법은 먼저 한국노년학회의 주요학술활동을 각 연도별 학술대회자료집과 문헌을 중심으로 개괄적으로 살펴본 후 한국노인정책의 변화를 통한 한국노년학회의 학술활동은 조선일보, 한겨레 신문검색과 한국언론진흥재단의 빅카인즈 검색을 통해 찾은 각 제도별 자료를 연도별로 비교하여 분석하였다. 다음으로 IAGG의 학술활동을 통한 한국노년학회의 학술활동은 학술대회 개최연도를 중심으로 국제기구의 노인관련 주요 아젠다를 포함하여 비교분석하였다. 분석결과 지난 40년간 한국노년학회는 다양한 학술활동을 국내외의 노인정책 변화에 민감하게 대응하면서 다학제적으로 혹은 국제적으로 활발하게 진행해 온 것으로 나타났다. 그럼에도 노년학회 구성원의 다양성 결여로 다루어지지 못했던 중요한 주제도 있었으며, 하나의 주제를 심도있게 지속적으로 논의하지 못했던 점도 지적될 수 있다. 향후 한국노년학회는 한국의 대표적 노인관련 학회로서 다학제적 학문적 특성을 살려 한국의 노인정책을 선도함은 물론 국제학회 및 기구들과의 연대를 통해 활발한 학술활동을 해 나가야 할 것이다.

The expansion of the world wide web has led to a huge amount of user generated content over different forums and social media platforms, these rich data resources offer the opportunity to reflect, and track changing public sentiments and help to develop proactive reactions strategies for decision and policy makers. Analysis of public emotions and opinions towards events and sentimental trends can help to address unforeseen areas of public concerns. The need of developing systems to analyze these sentiments and the topics behind them has emerged tremendously. While most existing works reported in the literature have been carried out in English, this paper, in contrast, aims to review recent research works in Arabic language in the field of thematic sentiment analysis and which techniques they have utilized to accomplish this task. The findings show that the prevailing techniques in Arabic topic-based sentiment analysis are based on traditional approaches and machine learning methods. In addition, it has been found that considerably limited recent studies have utilized deep learning approaches to build high performance models.

This study is caused by the urgent need to constantly fight against such a shameful phenomenon of society as corruption, the flourishing of which cannot be overlooked. This phenomenon has many negative manifestations and consequences, undermines the national security of the state, slows down the development of democracy, worsens the state of all spheres of life (economic, political, administrative, etc.), worsens relations with foreign partners, forms tolerance for corruption in the public consciousness. Today, the process of fighting corruption is extremely important for our country, because it depends on the independence, democracy, sustainability of Ukraine. However, there is a complex and ambiguous situation regarding this process, as there is a clear coordination of state policy in the fight against corruption, insufficient and narrow understanding of ways to combat it. There is a lack of efforts by the authorities to overcome corruption challenges and use ineffective means of combating them. Instead, corruption causes great material and moral damage to states as a whole and many of its citizens.

전 세계 해양의 대부분을 차지하는 공해는 해양바이오산업 성장에 필수적인 귀중한 해양 자원을 보유하고 있다. 이러한 글로벌 노력의 최전선에는 한국의 공해 자원 확보 및 기초효능(기초물질) 탐사사업이 있다. 이 연구는 대중의 인식을 측정하고 프로젝트의 이점을 정량화하여 향후 정책 결정에 대한 통찰력을 제공하고자 했다. 결과에 따르면, 연평균 지불의사액(WTP)은 3,778.8원으로, 전체 국민으로 확장하면 약 815.4억 원에 해당하는 것으로 나타났다. 본 연구의 의미는 두 가지이다. WTP를 기반으로 공해상 해양생명자원 확보의 경제적 가치는 연간 약 815억 원에 달할 정도로 상당하다. 이는 투자에 대한 WTP를 고려할 때 향후 정책 수립을 위한 중요한 참고 자료로 제공 가능하다. 해양생물자원에 대한 관심이 높아지고 있는 반면, 대중의 인식은 상대적으로 낮은 편이다. 그러나 본 사업은 해양바이오산업에 필수적인 데이터베이스를 구축하고 국제 해양생물자원을 확보하는데 있어서 중요한 역할을 하고 있다. 대중의 관심과 지속적인 지원은 이 사업 뿐만 아니라 향후 정책 구현에도 매우 중요하다. 대중의 인식을 높이는 전략은 필수적이며, 연구 결과는 향후 정책 결정에 귀중한 의견을 제공한다.
