Spearman Rho test shows that the value of r = -0.313 with a value of = 0.000 (ρ%). The results show that there is a relationship between the level of resilience and the level of anxiety of families who have the elderly in the COVID-19 pandemic at the Ketajen Village, Gedangan District. Conclusion: The implications of this study suggest that high levels of resilience allow for lower levels of anxiety. So, with the ability of a person's resilience, they will be able to take the meaning of failure and try better than they ever did, thereby reducing the risk of anxiety.

城市生态韧性时空变化及情景模拟研究——以杭州市为例

从韧性的特征角度研究城市生态韧性水平的变化机制，探究城市防范化解生态风险能力的时空差异，以此明确城市分区生态治理的重要任务，是实现韧性城市生态风险防控的有利途径。从抵抗力、适应力和恢复力3个方面构建了城市生态韧性评估模型，并以杭州为例，评估了其1995-2015年城市生态韧性时空变化格局，再者利用空间自相关模型对2015年杭州生态韧性分区管理模式进行了探究。最后，基于FLUS模型模拟了2035年基准和创新创业导向的两种情景下的城市土地利用空间格局，并评估了不同城市发展情景下的生态韧性水平空间分布情况。基于以上研究得到以下结论：（1）1995-2005年，生态韧性低值区域向东北和东南方向扩张，而生态韧性高值水平区域明显减少。2005-2015年，杭州西北部和西部原本存在的中等韧性水平区域也转为低等水平。（2）2015年，城市东北区域呈现低韧性水平-高排污企业密度的集聚分布，说明该区域环境生态风险防范化解能力比较低，需要加大环境监测和生态治理的资金投入，严防重大环境污染事件的发生。（3）创新创业导向的"创新天堂"城市发展情景比基准情景下2035年杭州整体生态韧性水平更高，主要影响因素在于前者的抵抗力水平和适应力水平明显高于基准情景。研究结果为韧性城市生态环境发展提供了理论依据。;Resilience is defined as the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and recovering quickly. Among various methods, the zoning ecological governance provides us with a potentially efficient way to promote resilient city development by enhancing resilience abilities and preventing ecological risks in cities. Recently, resilient city construction has been a hot issue for many areas in China due to the frequent natural disasters and human-induced incidents. However, little is known about how to improve resilience from a zoning ecological governance perspective. It is therefore an effective way to realize the ecological risk prevention and control of resilient city by identifying the key task of urban zoning ecological governance via investigating change mechanism of urban ecologically resilient level in context of resilient characteristics and exploring the spatio-temporal differences of prevention and reconciliation capacity of ecological risks. This paper constructed an urban ecological resilience evaluation model from three perspectives, namely, resistance, adaptability, and restoring force. Then, taking Hangzhou as an example, we evaluated the spatio-temporal changes of urban ecological resilience from 1995 to 2015 and explored Hangzhou ecological resilience zone governance based on the spatial autocorrelation model. Finally, the study applied the FLUS model to evaluate the different spatial patterns of urban land use and spatial distribution of ecological resilience levels under the simulated benchmark scenario and Innovation Paradise scenario in 2035. The results show that (1) from 1995 to 2005, high-value ecological resilience areas decreased significantly, and low-value ecological resilience areas expanded to the northeast and southeast areas; from 2005 to 2015, the medium-value resilience areas in the northwest and west of Hangzhou turned to low-value areas. (2) In 2015, areas with low-value ecological resilience and high-value pollution enterprise density clustered in the northeastern parts, where the ability to prevent the environmental and ecological risks was relatively low. (3) The overall ecological resilience level under the Innovation Paradise scenario with a more compact urban growth mode was higher than that under the baseline scenario with extensive urban expansion. As such, there are some significant practical implications for the ecologically resilient construction of Hangzhou city. Firstly, it is suggested that local governments should strictly control the occupation of wetlands and strengthen the quality and quantity of ecological land, which can promote the balance of spatial difference of ecological resilience. Secondly, since there exists obvious spatial heterogeneity of ecologically resilient levels in Hangzhou, it is important to establish zoning management mode for a successful urban eco-environment governance based on precise grid control and regulation of eco-environmental risks. Thirdly, as to northeastern parts where gathered grids with low-value ecological resilience and high-value pollution enterprise density, it is urgent to transfer the high emission enterprises, accelerate the locally industrial upgrading, and strengthen the local monitoring level of ecological quality, which can reduce the local ecological risk and prevent the risk diffusion. Besides, green landscape development and compact urban development should be encouraged in the future urban planning of Hangzhou city. Finally, it is vital to establish a reasonably ecological compensation system within the city, which can help to re-allocate the resources including labor, technology, and investments among various districts and counties to guarantee the powerfully environmental governance and sustainable ecological protection.

STUDENT’S MATHEMATICAL PROBLEM-SOLVING ABILITY WITH MATHEMATICAL RESILIENCE AND METACOGNITION SKILLS: A QUANTITATIVE ANALYSIS

One of the main goals in learning mathematics, both at the primary and secondary education levels, is to equip students with mathematical problem solving skills. This is important because there are so many problems in life that need to be solved by mathematics. However, several studies show that students' problem solving abilities are still low, so teacher efforts are needed to improve them. This research has a focus on improving students' mathematical problem solving abilities based on factors within the students themselves, namely Mathematical Resilience and metacognition abilities. This study uses a quantitative approach, with the type of expost facto research. The population in this study were elementary school students in Majalengka Regency with a sample of fifth grade students at SDN Jatipamor I, Panyingkiran District. The results showed that the problem solving abilities of students who had high Mathematical Resilience and metacognition skills were better than other students. Thus it can be concluded that Mathematical Resilience and metacognition skills have a very large influence on students' ability to solve mathematical problems.

The Role of food aid and livelihood interventions in mediating the relationship between household’s resilience and economic empowerment

The concept of resilience has been utilized to examine more complex ecological and socioeconomic systems such as agri-food systems in developing countries. Gaza has one of the high unemployment rates globally, therefore keeping people imprisoned in poverty and dependent on external support to existing. The strategy for poverty reduction in Gaza primarily consists of giving food aid or multi-purpose cash-based assistance and livelihood projects; nevertheless, this does not reduce unemployment or poverty in the long term. Non-Governmental Organizations (NGOs) have increased their efforts to provide more effective and comprehensive interventions to the affected populations, especially in the Gaza Strip. The research implemented a quantitative methodology distributed to over 300 household benefited from food aid and livelihood interventions through the NGOs in Gaza Strip. The questionnaire had been constructed based on the Likert Scale ranging from 1 (Strongly Agree) to 5 (Strongly Disagree). The data had been treated using SPSS statistical tool and AMOS for structural equation modeling and analysis to study the mediating effect of food aid and livelihood interventions on the relationship between household resilience and economic empowerment in the Gaza Strip. The research found that the resilience ability of many families in the Gaza Strip has increased because of the humanitarian assistance provided by NGOs, which lead to reducing poverty and household resilience plays a vital role in minimizing poverty and alleviating suffering through empowering and engaging them in the economy. The research also found that food aid tends to critically impact the relationship between household resilience and economic empowerment. NGOs play an essential role in engaging the poor in the economy through providing food security and encouraging new investments and efforts to improve help effectiveness via greater coordination among players involved in the implementation and better planning, targeting, and providing aid to people in Gaza Strip. The research findings also showed that livelihood interventions mediate the relationship between household resilience and economic empowerment in Gaza Strip. The structural model supports that the livelihood interventions modulated the association between household resilience and economic empowerment.

Resilience among older adults with Type 2 Diabetes from the Look AHEAD trial

There is growing interest in identifying factors protecting against aging-related decline. This cross-sectional study evaluated associations of self-reported resilience (ability to bounce back) with factors linked to aging-related decline among older adults with Type 2 diabetes (T2DM). Participants were 3,199 adults (72.2±6.2 years, 61% female, 61% white, BMI 34.2±8.2 kg/m2) enrolled in Look AHEAD (a multi-site RCT comparing weight loss to diabetes education among individuals with T2DM), who were followed observationally after the 10-year intervention was discontinued. The following items were assessed approximately 14.4yrs post-randomization: Brief Resilience Scale; overnight hospitalizations in past year; physical functioning measured objectively (gait speed, grip strength) and via self-report (Pepper Assessment Tool for Disability; Physical quality of life (QOL; SF-36)); a composite measure of phenotypic frailty based on having ≥3 of unintentional weight loss, low energy, slow gait, reduced grip strength, physical activity. Depressive symptoms (PHQ-9) and mental QOL (SF-36) were also measured. Logistic/linear regression was used to evaluate the association of these variables with resilience adjusted for age, race, and gender. Greater resilience was associated with lower BMI (p=.01), fewer hospitalizations (p=.02), better physical functioning (i.e., lower self-reported disability, better self-reported physical QOL, faster gait speed, greater grip strength and lower likelihood of meeting criteria for frailty; all p<.001), fewer depressive symptoms and greater mental QOL. Resilience is associated with better performance on indicators of overall functioning and risk for decline among older adults. Findings correspond with efforts to shift narrative on aging beyond ‘loss and decline’ to highlight opportunities to facilitate healthy aging.

On the taxonomy of smart city indicators and their alignment with sustainability and resilience

As interest in smart city initiatives continues to grow rapidly, various involved actors and stakeholders increasingly rely on assessment frameworks or indicator sets for different purposes such as monitoring and benchmarking performance, identifying strengths and weaknesses, and determining priority intervention areas. Accordingly, many smart city assessment frameworks and/or indicator sets have been developed in the last decade. To guide actors and stakeholders in their selection of the most suitable frameworks, several studies have examined contents and structure of smart city assessment frameworks or indicator sets. Such studies have significantly improved our understanding of the thematic focus of assessment tools and their methodological approaches. However, there is still a lack of knowledge on the taxonomy of smart city indicators. In addition, since other concepts such as sustainability and resilience are increasingly recognized to be connected to the smart city concept, more clarity on how different assessment frameworks or indicator sets are aligned with sustainability and resilience dimensions and characteristics is needed. To fill these gaps, we developed a taxonomy and examined 33 assessment frameworks or indicator sets in terms of indicator type, sectoral linkages, and alignment with sustainability and resilience dimensions and characteristics. In terms of indicator type, results show that output indicators are dominant but limited attention has been paid to impact indicators. In terms of sectoral focus, existing indicators are mainly related to information and communication technologies, economy, and governance. Regarding resilience abilities, indicators are mainly related to planning abilities and limited attention has been paid to recovery and adaptation. As for resilience characteristics, reasonable levels of alignment with resourcefulness and efficiency were observed, but indicators are not well-aligned with other important characteristics such as redundancy and diversity. Finally, in terms of sustainability, limited alignment with the environmental dimension was found, which raises concerns regarding the suitability of smart city indicators for guiding environmental sustainability and informing efforts aimed at addressing climate change issues. Results of this study can support interested stakeholders in their efforts to select the most suitable assessment frameworks or indicator sets for promoting resilient, smart, and sustainable communities.

Kontribusi Muhasabah dalam Mengembangkan Resiliensi Pada Orang Tua Anak Berkebutuhan Khusus

The phenomenon of the poor quality of parental care for children with disabilities makes resilience one of the psychological capital that contributes to improving the quality of care. This study describes how through a muhasabah intervention in Blimbingrejo Village, Nalumsari District, Jepara Regency. The purpose of this study was to provide information for parents of children with special needs about muhasabah interventions in developing the resilience abilities of parents when carrying out their care. The urgency of this research is to reduce parenting stress experienced by parents because of the developmental barriers of their children. This research is qualitative with a case study approach through in-depth interviews and observation techniques. The study results explain that the condition of children with special needs is often a stressor for their parents. However, parents can live with complete steadfastness as a form of their resilience. The pattern of resilience formed is supported mainly by thinking about what they are trying to do. There are indications of the meaning of resilience factors in the practice of muhasabah in the form of the ability to regulate emotions, develop optimism and empathy, control impulses and causal analysis, good self-efficacy and take wisdom as an indication of aspects of the reaching out process. The results of this study are helpful information in developing the concept and practice of caring for children with special needs.

A methodology to reconstruct LAI time series data based on generative adversarial network and improved Savitzky-Golay filter

High-quality leaf area index (LAI) data is essential for regional and global ecology, climate and environment research. However, there are still many quality problems in the continuity of current LAI time series products. Here we developed a new comprehensive three-step reconstruction method (GANSG) for satellite-retrieved LAI time series data based on generative adversarial network, improving the Savitzky-Golay (S-G) filter and median absolute deviation filter. We applied GANSG to the reconstruction of MODIS LAI data in China from 2001 to 2019. The reconstruction results show that the new method based on the unsupervised deep learning framework has an advantage in interpolating low-quality LAI with high precision. The new method can better retain high-quality pixel information to smoothen the interpolated LAI time series by improving the traditional S-G filter. Compared with the five other methods, including the adaptive S-G filter, double logistic, asymmetric Gaussian, modified temporal spatial filter and spatial temporal S-G filter, qualitative analysis showed the new method has a more resilient ability to handle the continuous loss of high-quality pixels and identify the phenological features of biomes. Quantitative analysis based on station observation showed that the new method performs best among the other three methods, with the optimal correlation coefficient of 0.84 relative to station observation and the lowest root mean square error of 0.71 m2/m2.

Analyzing Healthcare Facility Resilience: Scientometric Review and Knowledge Map.

In contemporary “high-risk” society, unexpected disasters (epidemics and extreme weather) and chronic pressures (aging problems) put tremendous pressure on healthcare facilities. Enhancing the healthcare facilities' resilience ability to resist, absorb, and respond to disaster disruptions is urgent. This study presents a scientometric review for healthcare facility resilience research. A total of 374 relevant articles published between 2000 and 2020, collected from Web of Science (WoS) core collection database, Scopus database and MEDLINE database were reviewed and analyzed. The results indicated that research on resilience in healthcare facilities went through three development periods, and the research involved countries or institutions that are relatively scattered. The studies have been focused on the subject categories of engineering, public, environmental, and occupational health. The keywords of “resilience,” “hospital,” “disaster,” “healthcare,” and “healthcare facility” had the most frequency. Furthermore, based on the literature co-citation networks and content analysis, the detected seven co-citation clusters were grouped into four knowledge domains: climate change impact, strengthening resilience in response to war and epidemic, resilience assessment of healthcare facility, and the applications of information system. Moreover, the timeline view of literature reflected the evolution of each domain. Finally, a knowledge map for resilience of healthcare facilities was put forward, in which critical research contents, current knowledge gaps, and future research work were discussed. This contribution will promote researchers and practitioners to detect the hot topics, fill the knowledge gaps, and extend the body of research on resilience of healthcare facilities.

DINAMIKA PSIKOLOGIS RESILIENSI PADA KORBAN GHOSTING

The phenomenon of ghosting is widely interpreted as a way of avoiding and breaking away from relationships without including an explanation. Psychologist Jennice Vilhauer said that ghosting is a silent treatment, which in psychology is seen as emotional cruelty. The purpose of this study is to explain the resilience dynamics of individuals who are victims of ghosting in Solo Raya. This study uses qualitative methods with interviews and observations. The subjects of this research are four students who live in Solo Raya with an age range of 19-25 years who have been victims of ghosting. Data analysis techniques used are data reduction, data presentation, and drawing conclusions. From the research, it was found that the subject had poor psychological dynamics. This can be seen from the negative changes in three aspects of psychological dynamics, namely cognitive, affective, and behavioral after experiencing a ghosting event. The resilience ability that is owned is quite good. This can be seen from four aspects, namely the ability to analyze problems, empathy, self-efficacy and positive self-achievement. However, there are three aspects that cannot be controlled by the subject, namely the ability to control emotions, control impulses and an attitude of optimism.Keywords: Ghosting; Psychological Dynamics; Resilience

A novel approach for sizing battery storage system for enhancing resilience ability of a microgrid

The deployment of battery energy storage systems (BESS) can provide numerous benefits including increased renewable energy penetration, improvements in power quality and reliability, reduction of demand peaks, and reduced greenhouse gas (GHG) emissions. During the implementation of BESS, one of the most crucial factors is to determine the optimal size of the BESS to permit the balance between the technical characteristics of the BESS and the additional overall cost including the economic operation of the microgrid (MG). Therefore, the optimal sizing of the BESS allows the storage of sufficient power during the change of dispatch from the distributed energy resources (DERs) or in critical events such as natural disasters. The proposed framework determines the optimal size of the BESS based on forecasting the natural disasters or the outage cases, to enhance the reliability and economic operation of the MG. In this study, two stages are proposed to determine the optimal size of BESS in the MG. The first stage is the forecasting stage, which predicts the location of the outage or the faults that may occur. In the second stage, obtain the optimal size of the BESS to minimize the total operation cost for an economic operation of the MG. The teaching-learning-based optimization (TLBO) combined with quadratic programming (QP) is applied to solve the proposed objective formulation proposed to minimize the total operation cost of the MG. This study has been investigated in a group of customers with a single type of MG using various fault scenarios. The obtained results are compared with the state of the art. The proposed technique yields very promising results and robust performance compared with the available methods in the literature.

The Response of Extracellular Polymeric Substances Production by Phototrophic Biofilms to a Sequential Disturbance Strongly Depends on Environmental Conditions.

Phototrophic biofilms are exposed to multiple stressors that can affect them both directly and indirectly. By modifying either the composition of the community or the physiology of the microorganisms, press stressors may indirectly impact the ability of the biofilms to cope with disturbances. Extracellular polymeric substances (EPS) produced by the biofilm are known to play an important role in its resilience to various stresses. The aim of this study was to decipher to what extent slight modifications of environmental conditions could alter the resilience of phototrophic biofilm EPS to a realistic sequential disturbance (4-day copper exposure followed by a 14-day dry period). By using very simplified biofilms with a single algal strain, we focused solely on physiological effects. The biofilms, composed by the non-axenic strains of a green alga (Uronema confervicolum) or a diatom (Nitzschia palea) were grown in artificial channels in six different conditions of light intensity, temperature and phosphorous concentration. EPS quantity (total organic carbon) and quality (ratio protein/polysaccharide, PN/PS) were measured before and at the end of the disturbance, and after a 14-day rewetting period. The diatom biofilm accumulated more biomass at the highest temperature, with lower EPS content and lower PN/PS ratio while green alga biofilm accumulated more biomass at the highest light condition with lower EPS content and lower PN/PS ratio. Temperature, light intensity, and P concentration significantly modified the resistance and/or recovery of EPS quality and quantity, differently for the two biofilms. An increase in light intensity, which had effect neither on the diatom biofilm growth nor on EPS production before disturbance, increased the resistance of EPS quantity and the resilience of EPS quality. These results emphasize the importance of considering the modulation of community resilience ability by environmental conditions, which remains scarce in the literature.

Leakage analysis of B shape ring self-energized seal in high pressure polythene polymerizer due to the aging of its nonmetallic ring

B shape ring with metal and nonmetallic materials is often used in the high-pressure polythene polymerizer for the self-energized seal. However, many factories reported that leakages often occurred when pressure is lower than 30 MPa, especially during the shutdown after a long period of operation. In this paper, the nonmetallic material Valqua 6502 were aged at 270 °C for 60 days, which is close to the working conditions of polymerizer. The compression and resilience abilities were tested and compared with those before aging. It reveals that the temperature aging reduces both compression and resilience abilities of the nonmetallic materials. FEM model was worked out for the simulation of sealing performance, which includes working conditions such as the assembly of the self-energized structure, the start up with temperature and pressure rise and the shutdown with temperature and pressure drop. It reveals that the sealing performance is not only influenced by the aging of nonmetallic ring, but also related with the interference fit to nonmetallic ring and clearance fit to the metal ring. Another kind of nonmetallic material XX300 was also aged as comparison, which performed better than the currently used one. With parameter studies, optimal interference and clearance fit were worked out for XX300 but failed for 6502. Therefore, when B shape ring with nonmetallic and metal materials works under high temperature and high pressure, the aging of the nonmetallic material should be considered to avoid decreasing its deformation and resilience ability and harming the sealing performance.

Contributions of Healthcare 4.0 digital applications to the resilience of healthcare organizations during the COVID-19 outbreak

In this paper, we examine the contributions of digital applications to the resilience of healthcare organizations during the COVID-19 outbreak. The studied applications are framed as Healthcare 4.0 (H4.0), comprising bundles of information and communication technologies used to improve operations in the health value chain. Data collection was carried out through semi-structured interviews with 10 senior managers from clinician and non-clinician departments of two large-sized Brazilian hospitals treating patients infected with SARS-CoV-2. Interviews were analyzed through content analysis, using data analysis categories related to the application focus (i.e., supply chain, patient diagnosis, patient treatment, and patient follow-up) and targeted resilience ability (i.e., monitor, anticipate, respond, and learn). Results indicate that applications oriented to supply chain and patient diagnosis contribute to all resilience abilities. Furthermore, depending on the resilience ability to be improved, different applications may be prioritized. Four research propositions for theory-testing in future studies are also presented.

Breeding Strategies for Weather Resilience in Small Ruminants in Atlantic and Mediterranean Climates.

Many efforts are being made to cope with negative consequences of climate change (CC) on livestock. Among them, selective breeding of resilient animals to CC is presented as an opportunity to maintain high levels of performance regardless of variation in weather. In the present work, we proposed a set of breeding strategies to improve weather resilience in dairy goats raised in north-western European Atlantic conditions and dairy sheep raised in Mediterranean conditions while improving production efficiency at the same time. Breeding strategies differed in the selection emphasis placed on resilience traits, ranging from 0 to 40% in the index. Simulations were carried out mimicking real breeding programs including: milk yield, length of productive life, age at first kidding and mastitis incidence in dairy goats and milk, fat and protein yields, and fertility for dairy sheep. Considering the particular climatic conditions in the two regions, the predicted future climate scenarios, and genetic correlations among breeding objectives, resilience was defined as stability to weather changes for dairy goats and as the ability to improve performance under heat stress for dairy sheep. A strategy giving a selection weight of 10 and 20% for goat and sheep resilience, respectively, resulted in the best overall genetic response in terms of both, production and resilience ability. Not considering resilience in breeding programs could lead to a major production loss in future climate scenarios, whereas putting too much emphasis on resilience would result in a limited progress in milk production.
