Economic Empowerment of Coastal Communities during the Covid-19 Pandemic in Johan Pahlawan District, West Aceh Regency

The economy of the coastal communities of West Aceh is still in the lower-middle category, coupled with COVID-19 which has made the situation more unstable. This study aims to determine the extent of Government Policy in Empowering the Economic Development of Coastal Communities in Johan Pahlawan District, West Aceh Regency. The method used is a qualitative approach with data collection techniques through observation, interviews and documentation. The results of the study show that government policies are: 1) People Centered, government policies related to human-centered community empowerment have been carried out by opening a network of cooperation in several places such as Sibolga, West Sumatra, Perlak to help fishermen to be able to export of fish, the policy provided is also not supported by administrative services from the sub-district. 2) Participatory, the fishermen community empowerment program during the COVID-19 pandemic is still not optimal in terms of community participation. The results show that there are several government programs that do not involve the community to be involved in it. The government does not pay attention to the empowerment of the fishing community's capacity itself, and what is currently needed by the fishing community. 3) Sustainable, the form of policies that have been carried out by the government in empowering the community has been carried out such as the program for providing BLT to fishermen. However, this program is considered less than optimal because it is not sustainable and there is no definite time for distribution
Experimental, analytical, and numerical investigations on the flexural and fatigue behavior of steel thin-walled X-section beam

Thin-walled hollow shapes are of great interest in many industries with weight constraints, due to their availability, low price, and strength-to-weight ratio. This paper presents the development, calculation, and production of a thin-walled X-section beam design with a unique section geometry. This hollow X-section beam geometry is a beam that has been developed to use shape-connected jaws on the beam and to use less bolts and mounting elements, and to easily change the positions of the parts mounted on the beam. The bending strength of this unique beam section was investigated, and the fatigue damage of the beam was also handled with technological methods. Using both experimental stress measurements and finite element solution, the static and fatigue strength of the beam were calculated with computer-aided engineering software. The FEM solution was performed nonlinearly by defining the linear elastic and plasticity properties of the material. Validation studies were carried out in the laboratory using three-point and four-point bending tests. These traditional experiments were supported by strain gauge technology that measures strain with 0.05% accuracy. The weight and bending strength of the X-section beam were compared with the hollow section square beam. X-section beam (S355J0H) has 13% lower bending strength than 120 × 120 × 8 mm (S355J0H) beam; however, it is 37% lighter. ANSYS-analytical test results of difference are 3.95%, and ANSYS-experimental test results of difference are 0.85%. Experiments showed that a ∼22% increase in strength is found in these corners depending on the production method. The fatigue behavior of the X-section beam was determined with the nCode DesignLife software using validated FEM solutions and fatigue curves of the materials. X-section beam developed for shape–connected assembly systems can be used especially in the formation of chassis with its superior assembly ability and bending strength, increasing functionality, and production speed.
Drag Predictions for Projectiles at Transonic and Supersonic Speeds

Abstract : The breakdown of the total drag into its individual components (pressure drag, viscous drag, and base drag) is important in the preliminary design stage of shell. Design codes are available to predict the individual drag components and thus, the total drag. Typically, the total drag predicted by these design codes agrees well with the total drag measured from flight tests. But, how well do these codes predict the individual drag components? Experimental verification of the prediction of the drag components is an extremely difficult task. Thus a Navier-Stokes computational procedure is used in this report to predict the individual drag components and test the accuracy of the predictions of the design codes. A thin-layer Navier-Stokes code has been used to compute the entire flow field over projectiles including the base region. Numerical calculations have been made for various Mach numbers in the transonic and supersonic regimes. Pressure drag, skin friction drag, base drag and thus, the total drag are obtained from the computed results. Comparison of drag has been made with available experimental data and also with predictions from design codes employing semi-empirical techniques.
Clinical trials field strategies with novel vaccines produced in Brazil

Objective: To report field strategies applied to clinical trials with vaccines developed by Instituto Butantan in Campinas, Brazil, in 2004 and 2006. Methods: This report describes the planning and the operational issues of two clinical trials conducted to evaluate immunogenicity and safety of recombinant Hepatitis B vaccine combined with BCG vaccine (BCG/VrHB-IB) and quadrivalent diphteria-tetanus-Haemophilus influenzae type b-cellular pertussis vaccine with low lipopolysaccharide (DTPm/Hib). Results: The main field strategies applied were: a) Partnership between the researchers and managers from Municipal Health Department and b) Research procedures at home or in Health Centers attended by participants. In the first study, BCG vaccine and VrHB-IB (combined or separated) were given to 552 newborns in the maternity, followed by two subsequent doses of VrHB-IB vaccine in households. The second study included 241 infants at Health Centers, which were vaccinated with DTPm/Hib vaccines concomitantly to the others recommended by the National Immunization Program. In both studies, blood samples were taken at home. No adverse events occurred during the experimental period. The field strategies used in those clinical trials allowed adherence by 90.2 and 93.8% of the participants of the first and second study, respectively. The vaccines were given according to the recommendation of National Immunization Program and blood samples were obtained according to the protocol schedules. Conclusions: The field strategies were important to guarantee enrollment and protocol compliance, causing little interference in families’ daily routine, pediatrics appointments and children’s vaccine.
Assessing the Outreach of Targeted Development Programmes—A Case Study from a South Indian Village

This paper explores beneficiary targeting of government programmes in a village in India. The analysis is based on all 228 households of the village and focus group discussions. The results show that there is a large exclusion error in targeted programmes, which have mostly excluded the poor and the needy. Most schemes have a prerequisite of asset ownership, such as agricultural land, which benefits resource-rich farmers with large landholdings. The relationship between benefits received and income of households is best represented by an inverted ‘u’-shape curve, indicating the middle-income category benefits more than the poorest. The scope and scale of welfare programmes, especially Direct Benefit Transfers, increased during the COVID-19 pandemic. For inclusion of the poorest of the poor, welfare and development schemes need to be decoupled from landownership in rural areas.
Chemical Structure and Distribution in Nickel–Nitrogen–Carbon Catalysts for CO2 Electroreduction Identified by Scanning Transmission X-ray Microscopy

Atomically dispersed metal–nitrogen–carbon (M–N–C) materials are a class of electrocatalysts for fuel cell and electrochemical CO2 reduction (CO2R) applications. However, it is challenging to characterize the identity and concentration of catalytically active species owing to the structural heterogeneity of M–N–C materials. We utilize scanning transmission X-ray microscopy (STXM) as a correlative spectromicroscopy approach for spatially resolved imaging, identification, and quantification of structures and chemical species in mesoscale regions of nickel–nitrogen–carbon (Ni–N–C) catalysts, thereby elucidating the relationship between Ni content/speciation and CO2R activity/selectivity. STXM results are correlated with conventional characterization approaches relying on either bulk average (X-ray absorption spectroscopy) or spatially localized (scanning transmission electron microscopy with electron energy loss spectroscopy) measurements. This comparison illustrates the advantages of soft X-ray STXM to provide spatially resolved identification and quantification of active structures in Ni–N–C catalysts. The active site structures in these catalysts are identified to be atomically dispersed NiNx/C sites distributed throughout entire catalyst particles. The NiNx/C sites were notably demonstrated by spectroscopy to possess a variety of chemical structures with a spectroscopic signature that most closely resembles nickel(II) tetraphenylporphyrin molecules. The quantification and spatial distribution mapping of atomically dispersed Ni active sites achieved by STXM address a target that was elusive to the scientific community despite its importance in guiding advanced material designs.
Influence of late Pleistocene sea-level variations on midocean ridge spacing in faulting simulations and a global analysis of bathymetry

Significance We address the hypothesis that changes in Pleistocene sea level have consequences for abyssal-hill bathymetry. A model illustrates how reductions in magma production caused by rising sea level could trigger faults at 100-ky intervals at intermediate spreading-rate ridges (>2.3 cm/y) and at 41-ky intervals at faster spreading-rate ridges (>3.8 cm/y). Analysis of 17 different regional ridge systems gives characteristic length scales that closely align with the predictions from the faulting model. Furthermore, a robust spectral peak is found at the 41-ky obliquity period at fast-spreading ridges. Together, these results constitute strong evidence for a pervasive influence of Pleistocene variations in glaciation and sea level on the pattern of abyssal hills.
On Frobenius full matrix algebras with structure systems

Let n ≥ 2 be an integer. In (5) and (6), an n × n A-full matrix algebra over a field K is defined to be the set Mn(K) of all square n × n matrices with coefficients inK equipped with a multiplication defined by a structure system A, that is, an n-tuple of n × n matrices with certain properties. In (5) and (6), mainly A-full matrix algebras having (0,1)-structure systems are studied, that is, the structure systems A such that all entries are 0 or 1. In the present paper we study A-full matrix algebras having non (0,1)-structure systems. In particular, we study the Frobenius A- full matrix algebras. Several infinite families of such algebras with nice properties are constructed in Section 4.
Constructing Definitive Screening Designs Using Conference Matrices

Jones and Nachtsheim (2011) propose a new class of designs for definitive screening. These designs have very nice properties for practical use. Their construction approach requires a computerized search. This short note provides a theoretical basis for design construction, making use of conference matrices. The design construction is straightforward, and the resulting design is always a global optimum definitive screening design. The proposed method only works when the number of factors is even, however.
Analysis of Extreme Temperature Variations on the Yunnan-Guizhou Plateau in Southwestern China over the Past 60 Years

Analysis of variations in 12 extreme temperature indices at 68 meteorological stations on the Yunnan-Guizhou Plateau (YGP) in southwestern China during 1960–2019 revealed widespread significant changes in all temperature indices. The temperature of the hottest days and coldest nights show significantly increasing trends, and the frequencies of the warm days and nights also present similar trends. The temperature of the coldest night has a significant and strong warming trend (0.38 °C/decade), whereas the frequency of frost days shows the fastest decrease (1.5 days/decade). Increases in the summer days are statistically significant, while a decreasing trend for the diurnal temperature range is not significant. Furthermore, there were significant differences in the changes of temperature indices between 1960–1989 and 1990–2019. Most parts of the YGP underwent significant warning, manifesting that the mountainous regions are relatively sensitive and vulnerable to climate change. The correlation coefficients between the temperature indices and various geographical factors (latitude, longitude, and height) reflect the complexity of regional temperature variability and indicate enhanced sensitivity of extreme temperatures to geographical factors on the YGP. It was also found that extreme temperatures generally had weaker correlations with the El Nino-Southern Oscillation, North Pacific Index, Southern Oscillation Index, North Atlantic Oscillation, and East Asian Summer Monsoon Index than with the South Asian summer monsoon index, Nino4 indices and Arctic Oscillation, and there were more insignificant correlations. Regional trends of the extreme temperature indices reflect the non-uniform temperature change over the YGP, which is due to the complex interaction between atmospheric circulation patterns and local topography. The results of this study have important practical significance for mitigating the adverse effects of extreme climatic changes, in particular for the YGP with its typical karst geomorphology and fragile ecological environment.
[Patient satisfaction with nursing care: a comparison between two hospitals].

This is a descriptive study with the objective of measuring and comparing patient satisfaction with the care provided by nurses as well as verifying differences in the satisfaction level in relation to the study's variables in two Sao Paulo hospitals. For data collection was used the Patient Satisfaction Instrument, translated and validated in Brazil. The sample was comprised of 211 patients, of which 128 from Hospital A and 83 from Hospital B. The statistical program SAS was used in the data analysis. The results showed that all patients reported a high level of satisfaction, and the five situations with highest averages were related to the domains Confidence and Professional. However, Hospital A patients showed higher satisfaction level than those of Hospital B. Considering the age variable, only the patients below the age of 60 in Hospital B tend to be more satisfied than the others.
System responses to Holocene relative sea-level rise and sediment supply in a macrotidal estuary

Estuaries are at the interface of marine and terrestrial systems and as such, are subject to environmental change arising from multiple driving mechanisms, with the interplay between the dominant controls varying spatially and temporally. Relative sea-level (RSL) change and sediment supply can play a significant role in driving environmental change. This study examines the relative influence of these drivers during the Holocene. Biostratigraphic records and RSL data are presented from two locations in the inner portion and upper reaches of the macrotidal Humber Estuary, eastern England. The results provide a new terrestrial limiting point and six sea-level index points, two of which at c. 1500 cal years BP provide the youngest sea-level index points for the inner estuary. An early-mid Holocene tidal lagoon system, that lacks modern equivalent, is recorded at one site. The results indicate a shift in the dominance of RSL rise driving the early Holocene creation of wetlands, to sediment supply dominating changes in the mid-late Holocene against the backdrop of a reduced rate of RSL rise, with a submergence of wetlands evident after c. 4000 cal years BP. The persistence of fen carr evident between c. 6800 and 5500 cal years BP suggests stability and resilience of the peatland system to continuing RSL rise. As rates of contemporary RSL rise increase, combined with climate and human impacts on the landscape, the drivers of change in these type of estuary systems will shift, with the records providing analogues of potential system responses that can help inform coastal management strategies.
Adipocytokine profile in children with Kawasaki disease at a mean follow-up period of 5.5 years: A study from North India

BACKGROUND Kawasaki disease (KD) is an acute self-limited vasculitis with a predilection for coronary arteries. Children with KD may have altered lipid metabolism and abnormal lipid profiles that may last for prolonged periods. However, there is a paucity of literature on the role of adipocytokines in KD. AIM To estimate the levels of adipocytokines (adiponectin, leptin and resistin) during the convalescent phase of KD. METHODS Twenty children, who had KD at least three years earlier, were enrolled in this study. In addition, 20 healthy controls were also enrolled. Clinical and laboratory profiles of patients were obtained from hospital records. Serum adiponectin, leptin and resistin levels were estimated by enzyme-linked immunosorbent assay. RESULTS Mean age of the patients in the study group was 10.15 ± 3 years and the male: female ratio was 1.5:1. Median serum resistin levels in patients with KD (27.77 ng/mL; [IQR: 18.66, 48.90]) were decreased compared to controls (21.20 ng/mL; [IQR: 14.80, 27.00]) (P = 0.04). Median serum leptin levels in cases and controls were 1.83 ng/mL; (IQR: 1.13, 3.80), and 1.10 ng/mL; (IQR: 0.41, 2.88), respectively (P = 0.09). Median serum adiponectin levels were similar in both cases (12.20 µg/mL; [IQR: 9.76, 17.97]) and controls (13.95 µg/mL; [IQR: 11.17, 22.58]); (P = 0.18). There was no significant difference in all 3 adipocytokines between children with (4/20) and without coronary artery abnormalities (16/20). CONCLUSION Serum resistin levels were significantly elevated in patients with KD during the convalescent phase compared to controls. Serum leptin levels appeared to be higher in patients with KD, although the difference was not statistically significant. Adiponectin levels were similar in both cases and controls. Raised resistin and leptin levels may partially explain lipid perturbations observed during the convalescent phase of KD.
DETERMINATION OF FACTORS AFFECTING THE GROWTH AND SURVIVAL OF SMALL AND MEDIUM ENTERPRISES (SMES) IN ANAMBRA STATE

The need to enhance the growth and survival of Small and Medium Enterprises (SMEs) necessitated the study, to ascertain the factors affecting the growth and survival of SMEs in Anambra State. Three research questions guided the study. A total of Two thousand, eight hundred and thirty-two registered SME owners and managers constituted the population. Simple random sampling was used to select 950 SME owners and managers as the sample for the study. Structured questionnaire validated by three experts with a reliability coefficient of 0.83 was the instrument for data collection. Data collected were analyzed using Mean and Standard deviation. The study found that factors such as; Inadequate experience, Lack of creativity, Lack of focus/determination (personal competencies) and Inadequate equipment and tools, Insufficient capital, Change in the market trend (environmental factors) affect the growth and survival of SMEs. Also, the study revealed the ways through which the growth and survival of SMEs could be enhanced as; Provision of adequate financial support to SME operators by the government, philanthropists and Nongovernmental Organizations (NGOs), Government provision of favourable business policies for SMEs, and Provision of business and managerial skill training programme free of charge to SMEs through public private partnership, among others. Based on the findings of the study, it was recommended among others that, SME owners and managers should equip themselves with the necessary competencies required for the growth and survival of SMEs either through formal training or apprenticeship system or both to enhance the growth and survival of Small and Medium Enterprises (SMEs).
Assessment of Social Trust in Relatives of Discharged Patients With Personal Consent and Other Relatives of Patients

Lack of social trust in the physician–patient relationship will disrupt health. Since social trust has not been sufficiently studied in patients' companions, this study investigates and compares social trust and its dimensions in companions of patients discharged against medical advice with total patients’ companions in the emergency room. In this cross-sectional descriptive-comparative study, 385 patients’ companions were enrolled. This study was done by a questionnaire with five subscales: honesty, frankness, cooperative tendency, confidence, and trust. Data were analyzed using descriptive statistics and analytical statistics methods. In this study, there was no significant difference between the mean score of social trust between companions of patients discharged against medical advice (61.11 ± 9.01) and patients discharged after treatment (62.27 ± 6.97). There was a significant relationship between the mean score of the 2 groups only in the frankness domain (P-value = .001). The level of social trust in the patients’ companions was moderate in both groups. Companions of discharged patients after completing the treatment process are more explicit than the companions of patients discharged against medical advice.
Self-Regulated Learning Skills and English Proficiency

This descriptive-correlational study investigated the self-regulated learning skills (SRL) and English proficiency (EP) of 338 Grade 7 students from eight secondary schools within PAHASUKI districts. It specifically determined the demographic profile of the respondents and the levels of their self-regulated learning skills and proficiency in English. Significant differences on their SRL and EP levels with respect to gender, age and income as well as and the relationship between SRL and EP were likewise determined. A Likert scale and teacher-made multiple-choice test were used to gather data, which were analyzed using frequency, frequency percentage, mean standard deviation, ANOVA and Pearson r. Majority of the students were female, within the appropriate age for Grade 7, and had low family income. Their level of SRL was high which differed significantly with respect to gender but not significantly with respect to age and income. Students’ English proficiency in terms of listening and speaking skills were within developing level their skills in speaking and writing were in beginning level. Difference on English proficiency was significant with respect to income but not significant with respect to gender and age. The relationship between self-regulated learning skills and English proficiency was weak but positive and significant. Interventions were recommended based on the findings.
