The recent COVID-19 pandemic is threatening human life and well-being, causing pain that has not been experienced before. Human security was summoned again as a result of the COVID-19 pandemic. However, it is paradoxically a threat to human security due to its inherent limitations and authoritarian control model. This paper first raises the analytical rigor of the concept of human security, focusing on COVID-19. Based on this, the practical usefulness of human security is improved by constructing a practical model that reflects the human security issues raised in reality. In particular, we approach the COVID-19 pandemic not from a natural disaster, but from the perspective of an artificial catastrophe caused by immorality and division in the international community. At the same time, we propose a multilateralism governance model that reflects the perspective of emerging security in order to realize human rights, the fundamental value of human security, and quarantine, a practical task in a balanced way.

Since greenhouse gas emissions increase continuously, the authorities have needed climate change countermeasure for adapting the acceleration of climate change damages. According to "Framework Act on Low Carbon, Green Growth", Korean local governments should have established the implementation plan of climate change adaptation. These guidelines which is the implementation plan of climate change adaptation should be established countermeasure in 7 fields such as Health, Digester/Catastrophe, Agriculture, Forest, Ecosystem, Water Management and Marine/Fisheries. Basically the Korean local governments expose vulnerable financial condition, therefore the authorities might be assessed the vulnerability by local regions and fields, in order to establish an efficient implementation plan of climate change adaptation. Based on this concepts, this research used 3 methods which are LCCGIS, questionnaire survey analysis and analysis of existing data for the multiphasic vulnerable assessment. This study was verified the correlation among 7 elements of climate change vulnerability by 3 analysis methods, in order to respond climate change vulnerability in rural areas, Seocheon-gun. If the regions were evaluated as a vulnerable area by two or more evaluation methods in the results of 3 methods' comparison and evaluation, those areas were selected by vulnerable area. As a result, the vulnerable area of heavy rain and flood was Janghang-eup and Maseo-myeon, the vulnerable area of typhoon was Janghang-eup, Masan-myeon and Seo-myeon. 3 regions (i.e. Janghang-eup, Biin-myeon, Seo-myeon) were vulnerable to coastal flooding, moreover Masan-myeon, Pangyo-myeon and Biin-myeon exposed to vulnerability of landslide. In addition, Pangyo-myeon, Biin-myeon and Masan-myeon was evaluated vulnerable to forest fire, as well as the 3 sites; Masan-myeon, Masan-myeon and Pangyo-myeon was identified vulnerable to ecosystem. Lastly, 3 regions (i.e. Janghang-eup, Masan-myeon and Masan-myeon) showed vulnerable to flood control, additionally Janghang-eup and Seo-myeon was vulnerable to water supply. However, all region was evaluated vulnerable to water quality separately. In a nutshell this paper aims at deriving regions which expose climate change vulnerabilities by multiphasic vulnerable assessment of climate change, and comparing-evaluating the assessments.

First proposed by Paul Crutzen and Eugene Stoermer in 2000, the concept of the Anthropocene has had staggering repercussions in a variety of disciplines. In response to the Anthropocene narrative as a problematization of the eco-ontological emergency that humanity is confronted with in the 21st-century, I will deal with the following theoretical themes in this article. Firstly, I will analyze the central agendas underlying the Anthropocene discourse: the expansion of human agency into the planetary level and the possibility of unprecedented catastrophes in the near future. Secondly, I will propose to address the Anthropocene discourse as problem-assemblage. Thirdly, I will examine Clive Himilton and Dipesh Chakrabarty's theses in order to understand the shock that was brought to bear on the humanities and social sciences by the Anthropocene narrative. Fourthly, I will reinterpret the allegory of the angel appearing in Benjamin's Theses on the Philosophy of History to explore new possibilities of transformative becoming of the subjectivity, focusing on the concept of patiency. Finally, I will present the concept of reflexive catastrophism.

Objectives: Minamata disease was an environmental health disaster of worldwide notoriety that occurred in Japan. The acknowledged patients total roughly 3,000, and the relieved victims currently include 77,099 cases. Still, many cases await acknowledgment or relief. The humidifier disinfectant issue is an environmental health catastrophe that took place in Korea. Over 9.98 million products spanning 43 brands of humidifier disinfectant have been sold and 835, cases have been recognized to date as relevant victims by the government. So far, 2,144 cases have been relieved by the fund of the producing companies. Four million consumers and 560,000 victims are estimated. Finding hints as to how to develop solutions in terms of fact-finding and prevention are the objectives of this study. Methods: Fields visits, interviews, and workshops as well as reference reviews have been conducted. A comparison was attempted to show the similarities and differences between the two disasters on 38 items. Results: Apparent similarities in the two disasters are the failure of industrial safety measures and governmental safety systems as well as relief systems for the victims. No comprehensive investigation was performed for all of the affected areas in Japan and all of the consumers in Korea. Both governments have tried to hide the faults and responsibilities of the companies and minimize the scale of the victims. Only after the government was changed through a general election did the new governments apologize and attempt to find political and social solutions through special relief laws. Conclusions: Over the process of each event, in the beginning, debates took place regarding the cause and the heath damages involved. For both, medical and toxicological relations are the keys while afterward finding a social solution became the subsequent issue.

Safety measures for tower cranes are extremely important among the seismic countermeasures at high-rise building construction sites. In particular, the collapse of a tower crane from a high position is a very serious catastrophe. An example of such an accident due to an earthquake is the case of the Taipei 101 Building (the author was the project director), which occurred on March 31, 2002. Failure of the bolted joints of the tower-crane mast was the direct cause of the collapse. Therefore, it is necessary to design for this eventuality and to take the necessary measures on construction sites. This can only be done by understanding the precise dynamic behavior of mast joints during an earthquake. Consequently, we created a new hybrid-element model (using beam, shell, and solid elements) that not only expressed the detailed behavior of the site joints of a tower-crane mast during an earthquake but also suppressed any increase in the total calculation time and revealed its behavior through computer simulations. Using the proposed structural model and simulation method, effective information for designing safe joints during earthquakes can be provided by considering workability (control of the bolt pretension axial force and other factors) and less construction cost. Notably, this analysis showed that the joint behavior of the initial pretension axial force of a bolt is considerably reduced after the axial force of the bolt exceeds the yield strength. A maximum decrease of 50% in the initial pretension axial force under the El Centro N-S Wave ($v_{max}=100cm/s$) was observed. Furthermore, this method can be applied to analyze the seismic responses of general temporary structures in construction sites.

Cormac McCarthy's The Road depicts a post-apocalyptic future in which the time and reason of catastrophe are not specified, but it can be seen to project the contemporary social and ethical concerns in the dismal setting. In this respect, the journey the man and boy depart for to the South is on one hand a journey to seek a warmer place to support their lives in the literal sense and, on the other hand, a journey to seek 'what a human being is' in the devastated world in a metaphorical sense since they face extremely harsh and tremendously poignant conditions in which their creed as human beings is tested. This paper aims to explore the hazards of the current society that the text criticizes and the morality and ethical values to be preserved and pursued. The second chapter examines how the text describes the contemporary crisis through the dark and coldness of the land and its sterility. The land produces almost nothing as the entire surface was scorched and is now covered with thick ashes. It shows perfectly a destroyed and irrecoverably frozen land. Throughout this desolate and ruined land, the atrocity and violence of the survivors goes beyond the limit. Ravaging strangers and plundering villages are widely spread. These conditions mirror the apparent selfishness and immorality of the recent society. The third chapter analyzes the man's inconsistent or dualistic narrative on the good. He knows what the good is but doesn't allow the boy to demonstrate the good behavior on others. His conflict is rooted in his hope to protect his son from being attacked by others. Therefore it can be interpreted that the meaning and orders of living in this post-apocalyptic period are uncertain and indecisive. The fourth chapter examines the belief the man and the boy clings to. Unlike the man's contradictory decisions, he shows definite firmness to be 'the good' by not eating people and carrying 'the fire.' Until he dies, the man endeavors to protect his son and have him acquire the moral conviction and strength to carry the fire in the world. In conclusion, the text reads the current society critically and highlights the importance of the humanity that must not be discarded throughout the generations.

We provide the first study on the occurrence of microplastics in Dal lake, Kashmir, India. Microplastics act as catastrophe that trigger many environmental problems. The key origins of microplastics are larger plastics, which split into smaller plastics after UV light disintegration. There is relatively little work carried out on the existence of microplastics. The present work has been undertaken on the occurrence of microplastics at four pre-selected sites (surface water) in Dal lake, Kashmir. The samples were taken to the laboratory to dissolve organic matter by using H2O2 (6%). To speed up the organic digestion; the treated mixture was heated on a hot plate at 70℃. The mixture was then subjected to density separation. The supernatant obtained was observed under the microscope (10X) and measurements were taken. At site-I, the microplastics ranged from 2-3 mm, site-II 5-6 mm, site-III 3-4 mm, site-IV 4-5 mm in thickness, indicating the presence of microplastics in the lake. The presence of microplastics indicated that the lake has undergone an anthropogenic change over a period of time. Our research highlights the value of enhancing the quality of the drainage system and sewage disposal. This work can be helpful to recognize successful microplastic control management techniques and possible threats associated with the Dal lake. So far, no such data on the presence of microplastics in Kashmir lakes is available.

Cyber security and resilience are phrases that describe safeguards of ICTs (information and communication technologies) from cyber-attacks or mitigations of cyber event impacts. The sole purpose of Risk models are detections, analyses, and handling by considering all relevant perceptions of risks. The current research effort has resulted in the development of a new paradigm for safeguarding services offered online which can be utilized by both service providers and users. customers. However, rather of relying on detailed studies, this approach emphasizes task selection and execution that leads to successful risk treatment outcomes. Modelling intelligent CSGs (Cyber Security Games) using MLTs (machine learning techniques) was the focus of this research. By limiting mission risk, CSGs maximize ability of systems to operate unhindered in cyber environments. The suggested framework's main components are the Threat and Risk models. These models are tailored to meet the special characteristics of online services as well as the cyberspace environment. A risk management procedure is included in the framework. Risk scores are computed by combining probabilities of successful attacks with findings of impact models that predict cyber catastrophe consequences. To assess successful attacks, models emulating defense against threats can be used in topologies. CSGs consider widespread interconnectivity of cyber systems which forces defending all multi-step attack paths. In contrast, attackers just need one of the paths to succeed. CSGs are game-theoretic methods for identifying defense measures and reducing risks for systems and probe for maximum cyber risks using game formulations (MiniMax). To detect the impacts, the attacker player creates an attack tree for each state of the game using a modified Extreme Gradient Boosting Decision Tree (that sees numerous compromises ahead). Based on the findings, the proposed model has a high level of security for the web sources used in the experiment.

This study aims to explore the direction of Christian public practice in the post-COVID era, seeking to overcome the uncanny feeling caused by increased division and exclusion during the pandemic period. Firstly, we will investigate the unequal impact of COVID-19 on the labor market and examine ways to achieve economic justice in the post-COVID era. Subsequently, we will deliberate the role of Christianity in establishing publicness in the digital world and virtual spaces. Finally, viewing COVID-19 as a catastrophe caused by an anthropocentric worldview and exploitation driven by greed, we will explore the tasks of Christianity to overcome the crisis of the Anthropocene. Christian public practice should fulfill its mission of care and stewardship not only in social context but also in an ecological dimension. The author proposes "planetary citizenship education" for a harmonious relationship between human species and the Earth they inhabit.

COVID-19 caused a catastrophe in human health. People infected with COVID-19 also suffer from various clinical illnesses during and after the infection. The Boerhavia diffusa plant is well known for its antihypertensive activity. ACE-II inhibitors and calcium channel blockers are reported as mechanisms for the antihypertensive activity of B. diffusa phytoconstituents. Various studies have said ACE-II is the virus's binding site to attack host cells. COVID-19 treatment commonly employs a variety of synthetic antiviral and steroidal drugs. As a result, other clinical illnesses, such as hypertension and hyperglycemia, emerge as serious complications. Safe and effective drug delivery is a prime objective of the drug development process. COVID-19 is treated with various herbal treatments; however, they are not widely used due to their low potency. Many herbal plants and formulations are used to treat COVID-19 infection, in which B. diffusa is the most widely used plant. The current study relies on discovering active phytoconstituents with ACE-II inhibitory activity in the B. diffusa plant. As a result, it can be used as a treatment option for patients with COVID-19 and related diseases. Different phytoconstituents of the B. diffusa plant were selected from the reported literature. The activity of phytoconstituents against ACE-II proteins has been studied. Molecular docking and ligand-protein interaction computation tools are used in the in-silico experiment. Physicochemical, drug-likeness, water solubility, lipophilicity, and pharmacokinetic parameters are used to evaluate phytoconstituents. Liriodenine has the best drug-likeness, bioactivity, and binding score characteristics among the selected ligands. The in-silico study aims to find the therapeutic potential of B. diffusa phytoconstituents against ACE-II. Targeting ACE-II also shows an effect against SARS-CoV-2. It can serve as a rationale for designing a drug for patient infected with COVID-19 and associated diseases.
