Authors: Xia Ding , Tang Huiming , Sun Sixuan , Tang Chunyan , Zhang Bocheng
Published: June 2022

A landslide susceptibility model based on a metaheuristic optimization algorithm (germinal center optimization (GCO)) and support vector classification (SVC) is proposed and applied to landslide susceptibility mapping in the Three Gorges Reservoir area in this paper. The proposed GCO-SVC model was constructed via the following steps: First, data on 11 influencing factors and 292 landslide polygons were collected to establish the spatial database. Then, after the influencing factors were subjected to multicollinearity analysis, the data were randomly divided into training and testing sets at a ratio of 7:3. Next, the SVC model with 5-fold cross-validation was optimized by hyperparameter space search using GCO to obtain the optimal hyperparameters, and then the best model was constructed based on the optimal hyperparameters and training set. Finally, the best model acquired by GCO-SVC was applied for landslide susceptibility mapping (LSM), and its performance was compared with that of 6 popular models. The proposed GCO-SVC model achieved better performance (0.9425) than the genetic algorithm support vector classification (GA-SVC; 0.9371), grid search optimized support vector classification (GRID-SVC; 0.9198), random forest (RF; 0.9085), artificial neural network (ANN; 0.9075), K-nearest neighbor (KNN; 0.8976), and decision tree (DT; 0.8914) models in terms of the area under the receiver operating characteristic curve (AUC), and the trends of the other metrics were consistent with that of the AUC. Therefore, the proposed GCO-SVC model has some advantages in LSM and may be worth promoting for wide use.

Published: June 2022

Electrostatic probe diagnosis is the main method of plasma diagnosis. However, the traditional diagnosis theory is affected by many factors, and it is difficult to obtain accurate diagnosis results. In this study, a long short-term memory (LSTM) approach is used for plasma probe diagnosis to derive electron density (Ne) and temperature (Te) more accurately and quickly. The LSTM network uses the data collected by Langmuir probes as input to eliminate the influence of the discharge device on the diagnosis that can be applied to a variety of discharge environments and even space ionospheric diagnosis. In the high-vacuum gas discharge environment, the Langmuir probe is used to obtain current–voltage (I–V) characteristic curves under different Ne and Te. A part of the data input network is selected for training, the other part of the data is used as the test set to test the network, and the parameters are adjusted to make the network obtain better prediction results. Two indexes, namely, mean squared error (MSE) and mean absolute percentage error (MAPE), are evaluated to calculate the prediction accuracy. The results show that using LSTM to diagnose plasma can reduce the impact of probe surface contamination on the traditional diagnosis methods and can accurately diagnose the underdense plasma. In addition, compared with Te, the Ne diagnosis result output by LSTM is more accurate.
Enhancing the Sense of Attention from an Assistance Mobile Robot by Improving Eye-Gaze Contact from Its Iconic Face Displayed on a Flat Screen
Authors: Rubies Elena , Palacín Jordi , Clotet Eduard
Published: June 2022

One direct way to express the sense of attention in a human interaction is through the gaze. This paper presents the enhancement of the sense of attention from the face of a human-sized mobile robot during an interaction. This mobile robot was designed as an assistance mobile robot and uses a flat screen at the top of the robot to display an iconic (simplified) face with big round eyes and a single line as a mouth. The implementation of eye-gaze contact from this iconic face is a problem because of the difficulty of simulating real 3D spherical eyes in a 2D image considering the perspective of the person interacting with the mobile robot. The perception of eye-gaze contact has been improved by manually calibrating the gaze of the robot relative to the location of the face of the person interacting with the robot. The sense of attention has been further enhanced by implementing cyclic face explorations with saccades in the gaze and by performing blinking and small movements of the mouth.
Crosstalk Correction for Color Filter Array Image Sensors Based on Lp-Regularized Multi-Channel Deconvolution
Authors: Kim Jonghyun , Jeong Kyeonghoon , Kang Moon Gi
Published: June 2022

In this paper, we propose a crosstalk correction method for color filter array (CFA) image sensors based on Lp-regularized multi-channel deconvolution. Most imaging systems with CFA exhibit a crosstalk phenomenon caused by the physical limitations of the image sensor. In general, this phenomenon produces both color degradation and spatial degradation, which are respectively called desaturation and blurring. To improve the color fidelity and the spatial resolution in crosstalk correction, the feasible solution of the ill-posed problem is regularized by image priors. First, the crosstalk problem with complex spatial and spectral degradation is formulated as a multi-channel degradation model. An objective function with a hyper-Laplacian prior is then designed for crosstalk correction. This approach enables the simultaneous improvement of the color fidelity and the sharpness restoration of the details without noise amplification. Furthermore, an efficient solver minimizes the objective function for crosstalk correction consisting of Lp regularization terms. The proposed method was verified on synthetic datasets according to various crosstalk and noise levels. Experimental results demonstrated that the proposed method outperforms the conventional methods in terms of the color peak signal-to-noise ratio and structural similarity index measure.
The Official Website as an Essential E-Governance Tool: A Comparative Analysis of the Romanian Cities’ Websites in 2019 and 2022
Authors: Gavriluță Nicu , Stoica Virgil , Fârte Gheorghe-Ilie
Published: June 2022

This paper aims to measure the quality of all Romanian cities’ websites in 2019 and 2022, before and after the disruptive event of COVID-19. Since the official websites are the core instrument of e-governance, the changes in the quality of Romanian cities’ websites reflect the changes in the development of urban e-governance in Romania. The COVID-19 lockdowns and contact restrictions and the moving of most activities into the online environment had the potential to impact the performance of Romanian cities’ websites significantly and catalyze the progress of local e-governance. The quality of Romanian cities’ official websites was measured using an adapted survey instrument proposed by Holzer and Kim and Manoharan, Melitski, and Holzer. The tool covers five critical criteria of website quality or performance: personal data security, usability, content, services, and citizen participation. The research results may seem contrary to expectations: the improvements of websites have been incremental rather than transformational. Although our research provides only a case study, we may assert that the reform of traditional administration remains a step-by-step process. Our study’s main contribution consists in showing that the progress of e-governance is an incremental process even in a situation of emergency that requires the moving of most activities into the online environment.

Published: June 2022

In the framework of introducing green strategies for food processing, the industrial orientation has shifted towards the replacement of conventional petroleum-based solvents with alternative eco-friendly ones. On this basis, the objective of this study was to synthesize a novel, tertiary, food-grade deep eutectic solvent, composed of glycerol, citric acid, and L-proline (GL-CA-Pro), and to test it as a solvent for the extraction of polyphenols from agri-food waste biomass. After an initial screening on various common residual materials (apple peels, lemon peels, orange peels, red grape pomace, olive leaves), evidence emerged that indicated GL-CA-Pro was more effective than other DESs commonly used for polyphenol extraction. Furthermore, extracts from red grape pomace (RGP) and olive leaves (OLL) were shown to contain higher level of total polyphenols and increased antioxidant activity. Process optimization for those two materials with the response surface methodology revealed that the major difference pertained to the extraction time. In addition, for both materials, GL-CA-Pro was shown to provide higher total polyphenol yields (53.25 and 42.48 mg gallic acid equivalents per g of dry mass, respectively) compared to water and 60% aqueous ethanol. However, the chromatographic analyses for OLL suggested aqueous ethanol was a more suitable solvent for some principal polyphenolic constituents. The RGP extract produced with GL-CA-Pro exhibited significantly stronger antioxidant effects compared to the aqueous and hydroethanolic extracts, but the outcome for the OLL extracts was diversified. It was concluded that GL-CA-Pro is a very efficient solvent for RGP polyphenols, but its efficiency regarding OLL was comparable to that of aqueous ethanol.
Analysis of Competitiveness in Agri-Supply Chain Logistics Outsourcing: A B2B Contractual Framework
Authors: De Arkajyoti , Singh Surya Prakash
Published: June 2022

COVID-19 has left some permanent effects on the Regional Agri-Supply Chain (RASC). It has single-handedly accelerated the RASC’s performance through the globalization of local products and increased e-agri-business, virtual retailing trends, and smart logistics and warehousing services. The post-COVID worldwide growing demand for regional agri-products has increased the competitiveness in logistics outsourcing. Motivated by these changing notions, this paper addresses two major questions—whether the competitiveness in logistics outsourcing allows the supply chain drivers (supplier, retailer, and 3PL) to form a sustainable B2B pricing supply chain model, and what will be 3PL firms’ strategic decisions to secure sustainable profit under this competitiveness? In the light of competitive literature, this paper proposes two decision-making approaches, optimistic and pessimistic, models them using the Stackelberg game theory, and solves them using the subgame perfect Nash equilibrium. The result shows that, even after competitiveness in logistics outsourcing, the supply chain drivers agree to form a contractual supply chain. However, the competitive strategy-making of 3PL firms is a little tricky. Each focal 3PL firm must have perfect information about the peer firm’s strategic movement to choose its preferable strategy. Further, they can preferably constrain their core competencies (service price and quality level) to assure a sustainable profit.

Published: June 2022

In this study, we utilize the advantages of offshore wind power resources in coastal areas to make up for the shortage of freshwater. At the same time, freshwater can be used as raw material to supply hydrogen energy. An operation strategy considering power and water input for an electrolyzer is proposed and an electrolyzer variable efficiency model under optimal operation mode is also proposed. Considering both energy benefits and operation and maintenance costs, this paper sets up the wind–hydrogen–water power grid system optimal operation model. Simulation analysis is carried out from the aspects of economy, accommodation, uncertainty of impacts of the reservoir capacity, water satisfaction, and so on. The results show that the accommodation rate reaches 98.2% when considering the proposed operation strategy. The average daily operating cost of the system reaches USD 3.9 × 104, and the strategy and model have good economic benefits and practical significance.

Published: June 2022

Forest fires are an important disturbance in forest ecosystems and can affect the structure and function of forests. These must be mitigated, to eliminate the associated harmful impacts on forests and the environment as well as to have a healthy and sustainable environment for wildlife. The northern region of China (Heilongjiang, Jilin, Liaoning, and Hebei provinces) is one of the important deciduous broadleaf forests and boreal-forest ecosystems in China. Based on the monitoring of historical remote-sensing products, this study analyzes and explores the spatial- and temporal-distribution patterns of forest fires in Northern China in 2020 and 2021, providing a strong scientific basis for forest-fire prevention and management. The number of monthly forest fires in the northern region in 2020 and 2021 was counted, to obtain seasonal and interannual forest-fire variation. The results show that the number of forest fires occurring in Heilongjiang, Jilin, and Liaoning provinces in 2021 is smaller than that in 2020. The occurrence of forest fires is, mainly, concentrated in spring and autumn, especially in April and October. The number of forest fires that occurred in Hebei Province in 2020 and 2021 was almost the same, showing a slight increasing trend, especially with more growth in February. It is worth noting that Heilongjiang Province is the region with the highest number of forest fires, regardless of the comparison of the total number of forest fires in two years or the number of forest fires in a single year. Spatial-clustering analysis (Ripley’s K) was used to analyze the spatial-distribution pattern of forest fires, in each province of northern China, and the results showed that forest fires were significantly aggregated in all four provinces. The experimental analysis conducted in this paper can provide local forest managers and firefighting agencies with the opportunity to better plan for fighting fires and improve forest-management effectiveness. Based on mastering the characteristics of the spatial and temporal dynamics of forest fires, fire-prevention publicity and education should be strengthened, and scientific forest-fire-prevention measures should be applied to plan reasonable forest-protection policies. This will contribute towards a healthy and sustainable environment.

Published: June 2022

When designing public spaces in large cities, a number of functional, communication, compositional, infrastructural, environmental and compositional factors should be taken into account, most of which relate to water elements. The appropriate location and form of water elements significantly affect the attractiveness and strengthening of the identity of places in cities. Fountains, artificial and natural urbanized watercourses, artistic installations and sculptures, as well as nature-based solutions that utilize water designed in public spaces significantly increase the social and aesthetic value of public spaces. The main aim of the presented research is to present a spectrum of solutions for water elements in public spaces of cities. The summary part describes guidelines and recommendations regarding the principles of designing the locations of fountains, watercourses and artistic objects that utilize water in public spaces in cities.

Published: June 2022

Device-to-device (D2D) communication is a promising technology which can improve the spectrum efficiency of cellular networks. Despite abundant research on resource allocation and interference cancellation for D2D communication, few works discuss how D2D is realized within cellular communication. In this paper, we propose a symmetric cooperative communication architecture combining security and energy efficiency, in which the users in 5G cellular networks can adaptively select the communication mode among cellular, direct D2D, and relay-assisted D2D communication according to the energy-consumption requirement. Considering the security aspect, we propose a novel relay selection strategy based on the asymmetry of social networks for the architecture. Firstly, we reduce the number of candidate relay devices based on energy consumption, the devices’ battery status, and the devices’ state. Then, an appropriate relay device is selected according to the proposed criteria, combining energy consumption, wireless channel quality, proximity prestige, and spreading ability. Simulation results reveal that, compared with conventional cellular communication and D2D communication, the proposed architecture can increase the number of users accessing the cellular networks simultaneously, improving the throughput and the security of data transmission. It can also significantly reduce the energy consumption as well as outage probability.

After discharge from the hospital for traumatic injury, patients and their caregivers face a period of increased vulnerability. This adjustment phase is poorly characterized, especially in low- and middle-income countries. We explored the experiences of patients and their caregivers in Northern Tanzania after hospitalization for a traumatic injury. Patients who received care for traumatic injury at the Kilimanjaro Christian Medical Center and their caregivers were selected as part of a convenience sample from January 2019 to December 2019. Analysts developed a codebook; content and analytic memos were subsequently created. We then applied the biopsychosocial model to further characterize our findings. Participants included 26 patients and 11 caregivers. Patients were mostly middle-aged (mean age 37.7) males (80.8%), residing in urban settings (57.7%), injured in road traffic accidents (65.4%), and who required surgery (69.2%). Most caregivers were female. Seven major themes arose: pain, decreased physical functioning, poor emotional health, lack of support, challenges with daily activities, financial strain, and obstacles to accessing healthcare. This study describes some of the difficulties transitioning back into the community after hospitalization for traumatic injury. Our work demonstrates the importance of mixed methods approaches in characterizing and addressing transitions of care challenges.

Published: June 2022

In fish-based foods, one of the effects of inappropriate storage can be the formation of biogenic amines. Among these, histamine is considered one of the most toxic. The purpose of the present study is to assess the occurrence of histamine in fish-based pet foods, and to evaluate the changes in histamine content during storage at different temperatures. For the analysis, an LC-MS/MS method was used. Fifty-eight pet foods were purchased, and an aliquot of them was analyzed just after opening the packages. Histamine was detected in 12 samples and concentrations ranged from 1.5 to 30.1 mg/kg. The remaining of each positive sample was divided into seven subsamples. One of them was used as a control sample and kept at −20 °C, while the other six were exposed to different environmental conditions. Samples exposed to room temperature showed no significant changes in histamine levels, while samples exposed to high temperatures showed significant increases in histamine content. Finally, samples exposed to refrigerator temperature showed a slight decrease in histamine levels. Under the experimental conditions, the EU limit of 100 mg/kg established for fishery products was never exceeded. These results seem to indicate a low risk of histamine intoxication in cats fed fish-based pet food.

Published: June 2022

METHs are drugs that enter wastewater through the feces and urine of users. Conventional wastewater treatment plants are not capable of removing this type of emerging contaminant, but, in recent years, techniques have been developed to abate drugs of abuse. The present investigation focused on obtaining the technique that keeps the best balance between the comparison criteria considered: efficiency; costs; development stage; and waste generation. That is why a bibliographic review was carried out in the scientific databases of the last eight years, concluding that the six most popular techniques are: SBR, Fenton reaction, mixed-flow bioreactor, ozonation, photocatalysis, and UV disinfection. Subsequently, the Saaty and Modified Saaty methods were applied, obtaining a polynomial equation containing the four comparison criteria for the evaluation of the techniques. It is concluded that the UV disinfection method is the one with the best relationship between the analyzed criteria, reaching a score of 0.8591/1, followed by the Fenton method with a score of 0.6925/1. This research work constitutes a practical and easy-to-use tool for decision-makers, since it allows finding an optimal treatment for the abatement of METHs.
Trends in Groundwater Levels in Alluvial Aquifers of the Murray–Darling Basin and Their Attributions
Authors: Fu Guobin , Rojas Rodrigo , Gonzalez Dennis
Published: June 2022

Groundwater levels represent the aggregation of different hydrological processes acting at multiple spatial and temporal scales within aquifer systems. Analyzing trends in groundwater levels is therefore essential to quantify available groundwater resources for beneficial use, and to devise plans/policies to better manage these resources. In this work, three trend analysis methods are employed to detect long-term (1971–2021) trends in annual mean/minimum/maximum depth to water table (DTW) at 910 bores. This analysis is performed in eight main alluvial systems in the Murray–Darling Basin (MDB), Australia, which concentrate nearly 75% of groundwater use. The results show: (a) an overall increasing trend in DTW across alluvial aquifers attributable to changes in recharge from rainfall and groundwater extraction; (b) the analysis methods employed show similar statistical significances and magnitudes, but differences exist; (c) the annual minimum DTW has a smaller trend magnitude than annual mean DTW, and the annual maximum DTW has a larger trend magnitude than mean DTW; (d) trends in annual rainfall and potential evaporation, and cumulative number of production bores, are consistent with the groundwater trends; (e) irrigation is responsible for some of the decreasing trend in groundwater level. These results could be used to target further research and monitoring programs, and inform groundwater resource management decisions in the MDB.
Estimating Canopy-Scale Evapotranspiration from Localized Sap Flow Measurements
Authors: Solum James , Malama Bwalya
Published: June 2022

The results reported in this work are based in part on measurements of sap flow in a few select trees on a representative riparian forest plot coupled with a forest-wide randomized sampling of tree sapwood area in a watershed located along the Pacific coast in Santa Cruz County, California. These measurements were upscaled to estimate evapotranspiration (ET) across the forest and to quantify groundwater usage by dominant phreatophyte vegetation. Canopy cover in the study area is dominated by red alder (Alnus rubra) and arroyo willow (Salix lasiolepis), deciduous phreatophyte trees from which a small sample was selected for instrumentation with sap flow sensors on a single forest plot. These localized sap flow measurements were then upscaled to the entire riparian forest to estimate forest ET using data from a survey of sapwood area on six plots scattered randomly across the entire forest. The estimated canopy-scale ET was compared to reference ET and NDVI based estimates. The results show positive correlation between sap flow based estimates and those of the other two methods, though over the winter months, sap flow-based ET values were found to significantly underestimate ET as predicted by the other two methods. The results illustrate the importance of ground-based measurements of sap flow for calibrating satellite based methods and for providing site-specific estimates and to better characterize the ET forcing in groundwater flow models.

Published: June 2022

As the primary ecological construction measure on the Loess Plateau, check dams play an essential role in developing agricultural production, improving people’s production and life, and replenishing groundwater. Soil water infiltration is the most important way to replenish groundwater in the dam land. In order to investigate the water infiltration process of check dams, an empirical model suitable for the simulation of the dam land infiltration process was selected. The soil water infiltration process of the check dam was studied by a field test and a model simulation. The results showed that there were few macropores in the dam, and the water mainly moved downwards in the form of matrix flow. Moreover, the stable infiltration rate of the dam site was low, and its infiltration process could be divided into three stages: rapid infiltration, fluctuating infiltration, and stable infiltration. In addition, the infiltration rate of a non-silted dense layer was 2.4~5 times that of a silted dense layer. The Horton model had a good fitting effect on the water infiltration process of the check dam and thus was suitable for the simulation and prediction of the water infiltration process of the dam. The results can provide a theoretical basis for efficient soil water utilization and infiltration simulation of check dam land.

reast milk is the most perfect food for babies, which provides high-value nutrients that required for growth, development and immunity. Healthy milk contains nutrients and does not contain contaminants (heavy metals), such as mercury. The use of mercury (Hg) in the process of separating gold in traditional gold mining through process of amalgamation in long time will result in mercury wastes that may pollute the river water, groundwater and soil. Mercury that pollutes the land will remain in the ground and then seep into groundwater or flow into streams when it rains. Mercury will be absorbed by plant roots and will mount up in fruits and leaves (vegetables), while the mercury in the river or pond water will accumulate in the body of the fish. People who live in gold mining areas, including nursing mothers who consume such food will indirectly consume mercury and it will accumulates in the body for a long time as well. This condition will cause health problems throuhout their lives. Mercury in body fluids, including in breast milk, will affect the protein content of · breast · milk · and inhibit enzyme activity. The aim of this study is to, identify the relationship between food consumption in the areas of gold mining with the quality (me'rcury and protein content) of breast milk. Subjects were pregnant women who live in gold mining areas in the District of Cineam Tasikmalaya Regency. Data collected include the food consumption of nursing mothers, protein and mercury in breast milk, and mercury in food. Food consumption data is collected by interview, whereas protein and mercury in breast milk and mercury in food obtained by using Atomic Absorption Spectrophotometer method (AAS). Statistical analysis used Spearman correlation between variables. The results showed average mercury content in some foodstuffs ranged from 0.01572 ppm -0.31086 ppm, the average daily intake of mercury is 25.81 µg, the average protein in breast milk is 1. 758 g/100 ml and the average mercury in breast milk is 1.011 ppb. Results of analysis among variables showed a significant correlation between the consumption of food (intake of mercury) a day with the content of mercury in breast milk (p = 0.043, r = 0.365) and mercury content in human milk with protein content in milk (p = 0.001, r =- 0.567).

Key Points

Dysnatremias were more common in patients with coronavirus disease 2019 (COVID-19) than in those without COVID-19.

Hypernatremia in patients with COVID-19 was associated with higher mortality than eunatremia.

Background

In patients without COVID-19, dysnatremia is associated with mortality. These relationships are not well established in patients with COVID-19. We tested the hypotheses that patients with COVID-19 were more likely to have dysnatremia than those without COVID-19 and that, among those with COVID-19, dysnatremia is associated with mortality.

Methods

We conducted a retrospective observational study of patients admitted to a tertiary care center in the Bronx, New York, during the COVID-19 surge from March 11 to April 26, 2020. Using multinomial logistic regression models, we compared the prevalence of hypernatremia (serum sodium ≥150 mEq/L) and hyponatremia (serum sodium <130 mEq/L) on admission between patients with and without COVID-19. Among patients with COVID-19, we used Cox proportional hazards models to examine the association of dysnatremia with mortality.

Results

Compared with those without COVID-19 (n=1265), patients with COVID-19 (n=3345) had a higher prevalence of hypernatremia (7% versus 4%, P<0.001) and hyponatremia (7% versus 6%, P=0.04). In adjusted models, COVID-19-positive patients had a higher likelihood of having hypernatremia (adjusted odds ratio=1.87, 95% CI, 1.3 to 2.57, P=0.001) compared with COVID-19-negative patients, whereas the association between hyponatremia and COVID-19 status was no longer significant (P=0.06). Among patients with COVID-19, 775 (23%) died after a median follow-up of 17 days (IQR 7–27 days). Among nonsurvivors, 15% had hypernatremia and 8% had hyponatremia on admission. Hypernatremia was associated with a higher risk of mortality (adjusted hazard ratio=1.28, 95% CI, 1.01 to 1.63, P=0.04) compared with patients with eunatremia.

Conclusions

In patients hospitalized during the spring 2020 COVID-19 surge, COVID-19 status was associated with hypernatremia on admission. Among patients with COVID-19, hypernatremia was associated with higher mortality. Hypernatremia may be a potential prognostic marker for mortality in COVID-19 patients.

Pasal 97 KHI belum memberikan penyelesaian secara tuntas mengenai harta bersama dalam hal apabila terjadi suatu perceraian, sebuah peraturan atau ketentuan hukum dibuat berdasarkan rasa keadilan, tetapi pada ketentuan ini, prinsip keadilan sepenuhnya belum terpenuh. Tekait hal tersebut diatas maka legal problem dari ketentuan uraian diatas adalah Kekaburan Rumusan. Pembagian harta bersama diatur dalam Pasal 97 KHI, di mana janda maupun duda  berhak separuh dari harta bersama, pembagian tersebut adil apabila suami dan istri memberikan besaran kontribusi yang sama selama perkawinan, salah satu pihak tidak melaksanakan kewajibannya, seperti suami tidak memberikan nafkah maupun istri yang tidak mengurus rumah tangga, keadilan adalah pembagian harta bersama dengan menilai besaran kontribusi para pihak, di mana pembagian yang adil tidak harus dibagi 50 persen bagi duda dan 50 persen bagi istri. Akan tetapi duda bisa mendapatkan bagian yang lebih kecil dari janda apabila kontribusinya kurang selama perkawinan dan tidakmenjalankan kewajibannya sebagai pencari nafkah. Terkait pada perkara gugatan pembagian harta bersama juga mempertimbangkan unsur keadilan bagi para pihak.Salah satu contohnya yaitu putusan di Pengadilan Agama Bantul dengan No.: 229/Pdt.G/2009/PA.BTL yang kemudian dikuatkan dengan putusan Pengadilan Tinggi Agama Yogyakarta No.: 34/Pdt.G/2009/PTA.Yk. Hingga akhirnya diperiksa pada tingkat kasasi di Mahkamah Agung dengan No.: 266 K/AG/2010 tanggal 21 Juli 2010. Pada perkara tersebut hingga tingkat akhir di MA, pembagian harta bersama diputus dengan pembagian ¾ untuk istri (penggugat) dan ¼ untuk suami (tergugat).

Due to the COVID-19 pandemic, some restaurants have had to adapt their business models to include innovative online food delivery (OFD) services (Gavilan et al., 2021). Customers are becoming more accustomed to utilising apps to order meals from their cellphones (Valley et al., 2022). Food delivery services have developed as a new trend in the food and beverage business as technology has advanced in the twenty-first century. People can now order food by simply pressing a button (Aryani et al., 2022). Food delivery platform operators have developed a new technological model for food delivery services that allows customers to use a mobile app to connect with a variety of local eateries and food providers. The COVID-19 epidemic and shutdown had an impact on small eateries and businesses during and after the outbreak. The Malaysian Ministry of Higher Education has cautioned students not to leave their existing residence within 24 hours of the announcement since the first MCO. Many students were stuck in university dorms and nearby non-residential rental housing areas. As a result, students always use the online food delivery service (OFD) to save time. Food Panda, Grab Food, Lalamove, and other online food delivery services are among the options.

Published: June 2022

The Covid-19 pandemic has triggered an adverse effect on the economy which have underscored the need to support and protect lower income groups. Poor and needy are among the low-income group who are the least ready individuals to adapt when emergency happens. Any calamities happened such as sickness, or accident can have a disastrous effect on their already low standard of living, which in turn decreases future income. As a result of this startling situation, the low-income group is recognized as at-risk population in the society due to the reality that they are plagued with various financial problems and still struggling to achieve socio-economic and health equalities (Haroun & Yusoff, 2019). We investigate the issues by evaluating the current risks encountered by Asnaf (Beneficiaries of Zakat fund). In particular, we focus on poor and needy group of people who had received financial assistance in the form of Entrepreneurship Programme organized by Lembaga Zakat Negeri Kedah. Even though Zakat collections kept rising year by year, it is still incapable to resolve the financial problems among the Asnaf especially during the time of emergency happens (Yahaya & Ahmad, 2019). The poverty issue and financial well-being are highly entangled; however, to the best knowledge of authors, there is limited studies that examine effective alternatives to channel fund to these poor and needy group who are deemed productive. Despite previous research has focused on Waqaf fund in proposing Microtakaful ( see for example Mikail and Saheed 2014,), there is a scarce empirical studies on the utilization of Zakat fund as a means to channel financial assistance to the poor and needy in the form of Microtaful scheme. Thus, this Study further notes that factors influencing the needs for Microtakaful protection, coupled with intervention from Zakat will influence financial well being of these targeted group of Asnaf. Besides, focus group and content analysis approach are used to gather primary data and identify and interpret relevant secondary data and Sharīʿah concepts in developing the Zakāh- and Waqf-based Microtakāful model.
