ABSTRACT: India is vulnerable to a large number of disasters. More than 58.6 % of the landmass is prone to earthquakes of moderate to high intensity; over 40 million hectares (12%) of its land is prone to floods and river erosion; close to 5,700 kms, out of the 7,516 kms long coastline is prone to cyclones and tsunamis; 68% of its cultivable area is vulnerable to droughts; and, its hilly areas are at risk from landslides and avalanches. WHO defines Disaster as “any occurrence that causes damage, ecological disruption, loss of human life, deterioration of health and health services, on a scale sufficient to warrant an extraordinary response from outside the affected community or area. Roles of nurse during disaster management includes to determine the magnitude of the event, define & understand the health needs of the affected groups, prepare the priorities and objectives, Identify actual and potential public health problems at the earliest & estimate resources needed to respond to the needs identified.

Annotation. Among the large joints, the knee joint is most often injured, which is due to the peculiarities of its structure and functional loads in the process of human life. The most common injuries are meniscus damages of the knee joint, that is the evidence of steady increase in the number of partial arthroscopic meniscectomies, which have become the most common orthopedic procedure. Diagnosis of meniscus damage is based on the results of clinical examination, sonography and MRI. Increasing the resolution of MRI machines, improving the technique of their implementation allows to improve the quality of diagnosis of meniscus ruptures and improve the results of surgical arthroscopic interventions on the knee joint. The aim of the study – to demonstrate the capabilities of high-intensity 1.5 Tesla MRI and to study the reliability of MRI signs of meniscus damage in comparison with the results of arthroscopic interventions in acute and chronic knee joint injury. The work is based on the results of MRI examinations and arthroscopic interventions of 247 patients with acute and chronic knee joint injuries aged 14 to 59 years. Medial meniscus damage was diagnosed in 206 (83.41%) patients. Lateral meniscus ruptures were diagnosed in 34 patients (13.76%). Simultaneous damage of both menisci was found in 7 (2.83%) patients. It was found that ruptures of the medial meniscus by location were: the root of the posterior horn of the medial meniscus in 4 (1.94%) patients, ruptures of the posterior horn in 82 (39.81%) patients. Injury of the posterior horn with the transition to the body of the meniscus was diagnosed in 117 (56.79%) patients. Anterior horn ruptures were detected in 3 (1.46%) patients. With ruptures of the lateral meniscus: damage of the root of the posterior horn of the lateral meniscus was found in 2 (5.88%) patients, damage of the posterior horn in 9 (26.47%) patients. Posterior horn rupture with transition to the body of the meniscus was diagnosed in 19 (55.89%) patients. Isolated ruptures of the anterior horn were found in 4 (11.76%) patients. Simultaneous damage to both menisci was found in 7 (2.83%) patients. 206 (83.40%) partial meniscectomies were performed during arthroscopic interventions and meniscus suturings were performed over 41 (16.60%) patients. In order to identify meniscus damage and their location during MRI knee joint investigations 21 pseudo-positive and 18 pseudo-negative cases of diagnosis were revealed. The sensitivity of MRI for defining damage and localization of meniscus rupture was 91,7%, specificity 92,6%, diagnostic accuracy 94,8%. Discrepancies in the evaluation of meniscal damage most often occurred in cases of their combined ruptures and degenerative changes in the menisci.

Nanotechnology is a broad term that covers many areas of science, research and technology. In its most basic form, it can be described as working with things that are small. The area of investigation is defined by the study, design, manipulation, manufacture, and control of materials or devices by physical or chemical means at resolutions on the order of one billionth of a meter. The potential for a wide range of applications makes a basic understanding of nanotechnology important to us. This article presents an introduction to nanotechnology and discusses the implications of it that could impact the human life in the near future.

AbstractThe operationalization of a concept is an important issue within social science research because it has to do with the content validity of the research concept and the accuracy of the variable. Nevertheless, the operating concept has been emphasized in the Western perspective on research, but it is not discussed much from an Islamic perspective. This is due to the fact that many Islamic perspectives emphasize the practical aspects of human life as seen through the revelatory source. To assess the situation, this paper reviews a comparative study that uses content analysis design and applied methods for comparing various dimensions of library methods. These methods operationalize both Western and Islamic perspectives in the area of community development. The data was coordinated and analyzed by QSR NVivo computer software. Overall, the study shows that the Islamic perspective has its own explanations with respect to the concept of participation, its own operationalization, and integral multiple-dimensions. Thus, this paper illustrates that the Islamic perspective has successfully proven its ability to conduct scientific research through its own ontology and epistemology of areas of community development

AbstractBased on evidence and theory, we state that facilitating and supporting people’s meaning-making processes are health promoting. Hence, meaning-in-life is a salutogenic concept.Authors from various disciplines such as nursing, medicine, psychology, philosophy, religion, and arts argue that the human search for meaning is a primary force in life and one of the most fundamental challenges an individual faces. Research demonstrates that meaning is of great importance for mental as well as physical well-being and crucial for health and quality of life. Studies have shown significant correlations between meaning-in-life and physical health measured by lower mortality for all causes of death; meaning is correlated with less cardiovascular disease, less hypertension, better immune function, less depression, and better coping and recovery from illness. Studies have shown that cancer patients who experience a high degree of meaning have a greater ability to tolerate bodily ailments than those who do not find meaning-in-life. Those who, despite pain and fatigue, experience meaning report better quality-of-life than those with low meaning. Hence, if the individual finds meaning despite illness, ailments, and imminent death, well-being, health, and quality-of-life will increase in the current situation. However, when affected by illness and reduced functionality, finding meaning-in-life might prove more difficult. A will to search for meaning is required, as well as health professionals who help patients and their families not only to cope with illness and suffering but also to find meaning amid these experiences. Accordingly, meaning-in-life is considered a vital salutogenic resource and concept.The psychiatrist Viktor Emil Frankl’s theory of “Will to Meaning” forms the basis for modern health science research on meaning; Frankl’s premise was that man has enough to live by, but too little to live for. According to Frankl, logotherapy ventures into the spiritual dimension of human life. The Greek word “logos” means not only meaning but also spirit. However, Frankl highlighted that in a logotherapeutic context, spirituality is not primarily about religiosity—although religiosity can be a part of it—but refers to a specific human dimension that makes us human. Frankl based his theory on three concepts: meaning, freedom to choose and suffering, stating that the latter has no point. People should not look for an inherent meaning in the negative events happening to them, or in their suffering, because the meaning is not there. The meaning is in the attitude people choose while suffering from illness, crises, etc.

<p> A water distribution network (WDN) is a critical and life-line infrastructure that transports and distributes water, an essential resource for human life, to local communities. A WDN is often modeled as a two-dimensional complex network consisting of vertices (nodes) and pipes (edges), and it has both characteristics of lattice-like and tree-like structures. With these characteristics, Son et al. (2021) proposed an approach to identify an optimal grid ratio in terms of functionality - efficiency and vulnerability - of a WDN using the lattice to tree network model (LTNM). Their result showed that the grid ratio of a real WDN is often significantly lower than the optimal value, which means that the function of the WDN can be improved by increasing the grid ratio. However, as the range of functions varies depending on where grids are located at a fixed grid ratio, simply adding pipes without considering their location does not incur a linear increase in system function. Therefore, it is important to identify the critical locations to add pipes where the functions of the system are most improved. In addition, it is necessary to determine if adding pipes is possible or not since pipe installation is not allowed for some places. In this study, we (1) identify possible spots where pipes can be added, (2) rank the identified spots where pipes are added regarding the extent of increments of function, and (3) propose an optimal (or a suboptimal) design with an optimally increased with grid ratio by adding pipes to the ranked locations in order. The results indicate that, the performance of WDNs which originally had low grid ratios are improved by adding pipes at reliable spots. The proposed approach illustrates how the structure and function of existing WDNs can be developed by modifying the proportion of grids.</p><p><strong> </strong></p><p><strong>Acknowledgments</strong>: This research was supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Science and ICT (NRF-2019R1C1C1008017).</p>
