  • 기후변화와 식품 관련 정보가 유기적인 관련이 있음에도 불구하고, 사실상 현실에서는 사용자들이 직접 그 관련성에 대한 관심을 가지고, 해당 정보에 대한 접근이 용이하다고 말하기는 어렵다.본 연구는 실제 사용자들이 직접적으로 노출되는 인터넷 포털 사이트의 뉴스 기사에 대한 빈도분석 및 연관관계 분석을 통해 기후변화 및 식품 관련 정보가 어느 정도의 연관성을 가지고 얼마나 자주 나타나고 있는지에 대해 파악하였다. 또한 추출된 기후변화 및 식품 관련 뉴스를 대상으로 기후변화 용어 사전과 식품 관련 용어 사전을 활용하여 기후변화 관련 용어와 식품 관련 용어의 총 59개의 연관관계 규칙을 도출함으로써, 특정 기후변화 관련 용어가 어떠한 식품 관련 용어와 연관관계를 갖는지 파악하여, 추후 두 용어를 패키징해 제공할 수 있는 발판을 마련하였다.

  • The purpose of this paper is to investigate the influence of ethical leadership in determining the organizations' individual-type ethical climate (self-interest, friendship, and personal morality ethical climate) in reducing employee turnover intention. It seeks to identify the role of individual-type climate in mediating the association between ethical leadership and employee turnover intention. Moreover, the moderation effect of emotional exhaustion among employees on the relationship between ethical leadership and turnover intention has been researched to establish the ethical degree of leadership. Using a sample of 260 questionnaires from employees working full-time in the banking sector, the results were analyzed in PLS-SEM. The results of the social exchange theory indicated that ethical leadership is vital in shaping the workplace's individual-type ethical climate and reducing employees' turnover intention. The findings demonstrate that the relationship between ethical leadership and turnover intention is mediated by an individual-type ethical climate, which means that employees in a positive ethical climate do not wish to leave immediately. Furthermore, emotional exhaustion was found to moderate the association between ethical leadership and employees' turnover intention under high emotional exhaustion, where low ethical leadership is experienced, reporting higher levels of turnover intention.

  • Understanding climate change is not only complex but also extensive. Humanity has never embarked on such a huge challenge of trans-national scope: a problem that began in the past continues now and will be continuing for a long time in the future. Nepalese have also significantly felt the impact of global climate change. The scenarios of climate change indicate that the increased temperatures will cause snow-melt which will result in floods, droughts, and uneven weather patterns. The impact of such unexpected climate hazards and weather patterns have already been felt and will continue to be felt in Nepal. These climate change-induced hazards and risks particularly threaten the agriculture sector, which results in food insecurity and makes poor and vulnerable people face increasingly unanticipated impacts to their lives and wellbeing. This paper explores the climate vulnerability of the Nepalese in terms of their physical, social, economic and primarily agricultural losses due to the increasing impact of climate change. The paper argues the need for a timely adaptation of measures to maintain an environment suitable for agriculture and for the well-being of the population residing in the area.

  • Data discovery and distribution application that is utilized by climate, high energy physics, and other scientific communities are experiencing performance and large scale data managing problems, that are rooted from the shortcomings of IP architecture. To solve this problem, newly developed data managing applications based on NDN architecture were introduced. In this letter, we present the federated NDN testbed with an NDN-based climate science application and the set of experiments that reflect the performance of NDN based climate application in general with determined and applied optimization.

  • A revolution in weather and climate forecasting is in progress. This has been made possible as a result of theoretical advances in our understanding of the predictability of weather and climate, and by the extraordinary developments in supercomputer technology. New problem areas have been discovered and different solutions have been found by the recent high performance computers whose performance has been increased rapidly. Such advances in the computational performance may change the strategy of development of numerical models and prediction methods. This paper discusses a brief history and current status of the supercomputers in institutions for research and forecast of weather/climate. The main purpose of this study is to provide the preliminary information about supercomputers such as architecture of system and processor. Such information would be useful for meteorologists to understand the features and the preference of supercomputers in each institution.

  • It is challenging work to predict weather and climate conditions of the future in advance. Since ENIAC was developed, weather and climate research areas have been taking advantage of the improvements in computer hardware. High performance computers allows researchers to build high quality models that allow them to make good predictions of what might happen in the future. Statistics on the high performance computers are one of the major interest to not only manufacturers but also the users such as weather and climate researchers. For this reason, the Top500 Supercomputer Sites Report has been being released twice a year since 1993 to provide a reliable basis for tracking and detecting trends in high performance computing. Using the Top500 Report, a short review on the supercomputer trends in weather and climate research areas is provided in this article.

  • Climate change is a constant threat to human life, and it is important to understand the public perception of this issue. Previous studies examining climate change have been based on limited survey data. In this study, the authors used big data such as news articles and social media data, within which the authors selected specific keywords related to climate change. Using these natural language data, topic modeling was performed for discourse analysis regarding climate change based on various topics. In addition, before applying topic modeling, sentiment analysis was adjusted to discover the differences between discourses on climate change. Through this approach, discourses of positive and negative tendencies were classified. As a result, it was possible to identify the tendency of each document by extracting key words for the classified discourse. This study aims to prove that topic modeling is a useful methodology for exploring discourse on platforms with big data. Moreover, the reliability of the study was increased by performing topic modeling in consideration of objective indicators (i.e., coherence score, perplexity). Theoretically, based on the social amplification of risk framework (SARF), this study demonstrates that the diffusion of the agenda of climate change in public news media leads to personal anxiety and fear on social media.

  • 현재 기상정보를 활용하고자 하는 수요는 증가하고 있으나 제공되는 기상기후정보는 한정적이다. 개선을 위해서는 기상기후 빅데이터 활용 플랫폼 지원, 정부 및 공공기관, 기업의 요구에 부응하는 기상기후 빅데이터 전문 인력 양성이 필요하다. 기상기후 빅데이터는 다양한 분야에서 활용 가능한 고부가가치 서비스 제공이 필요하며 서비스의 확대 및 새로운 콘텐츠 개발을 위하여 산업 분야별 유형별 특성에 맞는 맞춤형 서비스가 제공되어야 한다. 맞춤형 서비스를 제공하기 위해서는 국가차원의 협업생태계 조성이 필수적이다. 협업생태계 조성 환경을 만들기 위해서는 해양정책과 기상정책의 융합, 해양학과 기상학의 융합, R&D 기초연구와 응용연구의 융합이 필요하다. 이후 수요분석, 생산정보공유, 단일화 순서로 협업생태계를 구축할 수 있다.

  • Recent changes in the global climate environment have resulted in a wide variety of climate-related disasters, including floods, tidal waves, forest fires, droughts, etc. In addition, global warming raises the risk of food poisoning, which may increase the spread of infectious diseases and alter their structure. Under these circumstances, it is necessary to provide accurate and persuasive information to consumers so that they can be fully informed of climate change and alter their behavior accordingly. Therefore, the intention of this study was to develop posters and contents for image production related to climate change and food safety. The posters are focused on consumers with headings such as "Climate Change Threatening Food Safety", "Earth getting warmer, your dining table is at risk", "Warning signs ahead for the globe", and more. Five poster drafts were selected initially, and a survey was carried out amongst 1,087 people regarding their preferences, with the most preferred design chosen. The images related to climate change and food safety defined climate change, how it relates to food safety, the risks it poses to the food industry, and lastly, how the public can respond in the future. Therefore, to further communicate the importance of food safety to consumers, the development, education, and promotion of these contents should be performed to provide safety information to consumers in the future.
