Objective : Several earlier studies have reported similar symptoms in patients with posttraumatic stress disorder (PTSD) who have been repeatedly exposed to relevant media after disasters and trauma. This study aimed to examine the effects of indirect trauma experience through media rather than direct traumatic events on an individual's social life. Methods : Five hundred and fifty-four individuals participated in our online, self-reported questionnaire survey. All subjects were asked to complete a demographic questionnaire, Posttraumatic Diagnostic Scale, Beck Depression Inventory, the Impact of Event Scale-Revised, State-Trait Anxiety Inventory, Korean version of Alcohol Use Disorder Identification Test, Patient Health Questionnaire-15, Suicidal Behaviors Questionnaire-Revised. Participants were assessed in regards to their experience of violent media exposure within the past three months. Results : Data from our study indicates that the group exposed to violent media had significantly higher perceived stress, physical symptoms, insomnia, and suicide ideation in comparison to the control group. Among the major symptoms of PTSD, the proportion of intrusion symptoms was relatively high in the media exposed group. Conclusion : This suggests that indirect trauma caused by media exposure could cause post-traumatic stress symptoms. The PTSD caused by indirect trauma may have slight differences from the PTSD caused by direct trauma. Therefore, it is necessary to understand, prevent, and control the adverse effects of media.

In the spring, 2020, the pandemic caused quarantine and all educational institutions switched to distance learning, which led to significant changes in the field of education around the world. It has become necessary to build its capacity to provide distance learning to protect education and create opportunities for more individualized approaches to teaching and learning not only during future pandemics but also during other possible issues, such as natural disasters, when a developed flexible curricula could be taught face-to-face or online. The article presents an analysis of distance education in the world during a pandemic, analyzes significant changes, and implements measures in the field of education in Ukraine and around the world. The role of public and international organizations in the implementation of quarantine in the conditions of COVID-19, which partially took over the functions of state and local authorities, is emphasized. The closure of schools under COVID-19 has led to a de facto deterioration in learning outcomes, so we have analyzed the effects of distance learning and digital inequality in the world. It is shown how the COVID-19 pandemic affected access to public services in Ukraine.

Recently, natural disasters caused by climate change have become more frequent across the world. Our country is also not exceptional, and it is urgent to come up with appropriate measures in the agricultural sector as the size and intensity of drought are becoming severe. Consequently, the Ministry of Agriculture and Food has continuously raised the need for efficient water management and governance to overcome the periodic drought. Thus, there is a need for water-saving education and water conservation governance for sustainable and efficient use of agricultural water. Governance is a cooperative mechanism involving various stakeholders, such as central, local, civil society, and businesses, to solve regional or social problems, with different definitions and concepts depending on the field or scope. In this study, we aim to present basis of a governance framework for direct water management participation involving the key agricultural water use stakeholders to imbibe the culture of water savings and conservation practices. Based on this, water-saving governance was established and operated in Gyeongju and Yeoju, in South Korea as a 'water conservation practice', while the water management status of local farmers, the reliability and importance of stakeholders, and the need for governance were investigated. The results indicate that the involvement of various stakeholders in the governance of water management yielded water-saving effects. This study provides the directions of making a framework for water-saving governance establishment and operation. It is expected that sustainable agricultural water use can be achieved in response to climate change if the governance builds and operates with agricultural water use stakeholders based on the continuous government supports.

The severe effects of climate change, such as global warming and the El Niño phenomenon, have become more prevalent. In recent years, natural disasters such as drought, heavy rain, and typhoons have taken place, resulting in noticeable damage. Korea is affected by droughts that cause damage to rice fields and crops. Societal interest in droughts is growing, and measures are urgently needed to address their impacts. As the demand for high-quality agricultural products expands, farmers have become more interested in water management, and the demand for field irrigation is increasing. Therefore, we investigated water demand in the irrigation of drought-vulnerable crops. Specifically, we determined the water requirements for crops including cabbage, red pepper, apple, and bean in four regions by calculating the consumptive water use (evapotranspiration), effective rainfall, and irrigation capacity. The total consumptive water use (crop evapotranspiration) estimates for Dangjin-si (cabbage), Yesan-gun (apple), Cheongyang-gun (pepper) in Chungnam, and Goesan-gun (bean) in Chungbuk were 33.5, 206.4, 86.1, and 204.5 mm, respectively. The volumes of groundwater available in the four regions were determined to be the following: Dangjin-si, 4,968,000 m³; Yesan-gun, 4,300,000 m³; Cheongyang-gun, 1,114,000 m³, and Goesan-gun, 3,794,000 m³. The annual amounts available for the representative crops, compared to the amount of evapotranspiration, were 313.9% in Dangjin-si, 29.5% in Yesan-gun, 56.1% in Cheongyang-gun, and 20.1% in Goesan-gun.

전 세계의 도시화율이 급증하여 메가시티의 수가 점차 증가하고 있다. 이와 더불어, 기후변화, 사회 발전 및 과학기술의 발전으로 인해 재난의 종류가 다양해지고, 피해 규모도 확대되고 있다. 특히, 메가시티는 1,000만 명 이상의 인구와 이들의 활동 공간이 초밀집·초연결·초융합되어 재난 발생 시 'n'차로 확대되어 피해가 가증되기 쉽다. 하지만, 메가시티는 한 나라의 정치, 경제, 문화 등의 중심지이다. 이로 인해, 메가시티에 복합재난이 발생한다면 국가안보차원에서의 위기로 발전될 수 있다. 따라서 메가시티가 예측능력, 복합대응능력, 신속대응능력 및 회복 탄력성을 갖출 수 있도록 범정부 차원의 노력을 집중할 필요가 있다.

Recently, with the development of data processing technology and the increase of computational power, methods to solving social problems using Artificial Intelligence (AI) are in the spotlight, and AI technologies are replacing and supplementing existing traditional methods in various fields. Meanwhile in Korea, heavy rain is one of the representative factors of natural disasters that cause enormous economic damage and casualties every year. Accurate prediction of heavy rainfall over the Korean peninsula is very difficult due to its geographical features, located between the Eurasian continent and the Pacific Ocean at mid-latitude, and the influence of the summer monsoon. In order to deal with such problems, the Korea Meteorological Administration operates various state-of-the-art observation equipment and a newly developed global atmospheric model system. Nevertheless, for precipitation nowcasting, the use of a separate system based on the extrapolation method is required due to the intrinsic characteristics associated with the operation of numerical weather prediction models. The predictability of existing precipitation nowcasting is reliable in the early stage of forecasting but decreases sharply as forecast lead time increases. At this point, AI technologies to deal with spatio-temporal features of data are expected to greatly contribute to overcoming the limitations of existing precipitation nowcasting systems. Thus, in this project the dataset required to develop, train, and verify deep learning-based precipitation nowcasting models has been constructed in a regularized form. The dataset not only provides various variables obtained from multiple sources, but also coincides with each other in spatio-temporal specifications.

본 연구는 유엔 사무총장이 "코로나 19는 여성의 얼굴을 한 위기이다" 라고 언급한 것에서 볼 수 있듯이, 코로나 19 팬데믹으로 인하여 가장 큰 위기와 고통, 어려움에 처한 여성들의 상황을 통계자료들와 학술연구결과들을 통하여 경제적, 사회 문화적, 심리 정서적 측면에서 구체적으로 다루고, 이 문제들이 어떻게 "돌봄"에 관련되어 나타나는지 살펴보았다. 그리고 이러한 문제들과 위기에 대한 교회의 한 대응으로서 "돌봄윤리"와 "돌봄목회"를 통한 목회신학적 성찰을 도모하였다. 교회의 "돌봄목회"는 교회내의 개인적 돌봄 뿐 아니라 사회, 문화, 경제, 정치, 생태계적 이슈들에도 확장되며, 교회는 공공성을 가지고 재난과 관련된 이러한 이슈들에 응답하는 선교적 사명을 지닌다. 나아가 교육목회를 통해, 돌봄과 불평등에 대한 가치관과 사고방식의 변화와 디아코니아, 교회공동체의 사랑의 돌봄이 격려되어야 할 것이다.
