Understanding mobile application development and implementation to monitor Posyandu data in Indonesia: a 3-years hybrid action research to build “a bridge” from the community to national use

Background. There is a small number of facts available to understand better how mobile health application technology on mother and child health (MCH) is developed. This study is aimed: (a) to explore the process of developing the mobile app in MCH community-based services in the Indonesian setting/Posyandu, (b) to perform feasibility assessment among the community health workers (CHWs), and (c) to see the potential use of the mobile app in the country. Method. Using a hybrid method in which the action research principles and the mixed-method, which comprise qualitative and quantitative methods, were synergistically combined for the end-users. The study was conducted in Pasawahan sub-district, Purwakarta, Indonesia, from 2017 to 2019. Content analysis, coding, and categorizing were carried out using NVivo 12 Pro for the transcribed data. Wilcoxon Test (2018 and 2019) was conducted using STATA 15 Special Edition. Results. (1) The use of a CHW notebook for data entry in the Posyandu information system book delayed the data reporting process, resulting in the need to develop a mobile app; (2) There are significant differences of CHW’s knowledge (p=0.000) and skills (p=0.0097) on training (2018) and Posyandu phases (2019); (3) As many as 964 posyandu are registered to Posyandu mobile app from almost all provinces in Indonesia. Conclusions. The 3-years hybrid approach suggests the crucial phases to develop a mobile app in a more user-friendly manner to substitute the use of CHW’s old-fashion book use and that its implementation is promising for national use.
Optimal Fault Tolerance Strategy Selection for Web Services July 4 , 2009 1 Introduction

Web services are self-contained, self-describing, and loosely-coupled computational components designed to support machine-to-machine interaction by programmatic Web method calls, which allow structured data to be exchanged with remote resource. In the environment of service-oriented computing (Zhang et al, 2007), complex service-oriented systems are usually dynamically and automatically composed by distributed Web service components. Since the Web service components are usually provided by different organizations and may easily become unavailable in the unpredictable Internet environment, it is difficult to build highly reliable service-oriented systems employing distributed Web services. However, reliability is a major issue when applying service-oriented systems to critical domains, such as e-commerce and e-government. There is thus an urgent need for practical reliability enhancement techniques for the service-oriented systems. By tolerating component faults, software fault tolerance is an important approach for building reliable systems and reducing the expensive roll-back operations in the long-running business processes. One approach of software fault tolerance, also known as design diversity, is to employ functionally equivalent yet independently designed program versions for tolerating faults (Lyu, 1995). This used-to-be expensive approach now becomes a viable solution to the fastgrowing service-oriented computing arena, since the distributed Web services with overlapping or equivalent functionalities are usually independently developed by different organizations. These alternative Web services can be obtained from the Internet and employed for the construction of diversity-based fault tolerant service-oriented systems. By fault tolerance techniques, long-running business process roll-backs can be reduced since failures of the components can be tolerated by employing alternative candidates (other Web services). Although a number of fault tolerance strategies have been proposed for establishing reliable traditional systems (Lyu, 1995), in the fast-growing field of service computing, systematic and comprehensive studies on software fault tolerance techniques to transactional Web services are still missing.
Influence of river discharge on grass carp occupancy dynamics in south‐eastern Iowa rivers

Despite the longstanding presence of grass carp Ctenopharyngodon idella in the Upper Mississippi River (UMR) watershed, information regarding their populations remains largely unknown, in part because capture is difficult. Occupancy models are a popular wildlife assessment tool to account for imperfect detections but have been slow to be adopted in fisheries. Herein, we used occupancy modelling to evaluate the influence of two environmental covariates (river discharge and water temperature) on grass carp occupancy, extinction, colonization, and detection at nine sites within south‐eastern Iowa rivers from April to October 2014 and 2015. Grass carp were detected at least once at all but one site. The most parsimonious model indicated that grass carp colonization probability increased from 0.15 to 0.67 with increases in river discharge. In contrast, occupancy (0.20), extinction (0.29), and detection (0.50) probabilities were temporally constant. Models indicated that water temperatures did not influence grass carp extinction or colonization probabilities relative to river discharge. Cumulative grass carp detection probability approached 1.0, whereas conditional occupancy estimates were less than 0.1 when using five or more sampling transects. The use of a robust design occupancy model allowed us to estimate site occupancy rates of grass carp corrected for imperfect detections, while demonstrating the importance of river discharge for site colonization. These results can be used to assess the distribution of a cryptic fish while helping to guide grass carp sampling and removal efforts.
Open-Cloud Computing Platform Design based on Virtually Dedicated Network and Container Interface

 Abstract Background/Objectives: Companies that perform services based on the data center use server virtualization technology to reduce costs. Most companies use hypervisor-based server virtualization technologies, which require hardware virtualization to handle many I/O and resources at the kernel level. Methods/Statistical analysis: hypervisor-based technology is limited by low speed, which can be resolved by using container-based virtualization technology. However, container-based network also has issues. It is difficult to construct flexible container-based network, and data transmission performance declines if the existing container network interface is used. Findings: To solve these problems, this paper uses SDN Technology and Kubernetes, which is used as a container orchestration system. Furthermore, network configuration is linked with CNI of Kubernetes and virtually dedicated network (VDN) application based on the Open Network Operating System (ONOS) Controller for SDN. In other words, we have developed a new CNI by deleting the overlay network and a virtual bridge used in the existing Kubernetes. The newly developed CNIs are directly connected to the host network for high-performance network operations. Improvements/Applications: The Interconnection of VDN and Kubernetes provides high performance and flexible networking capability. We compare the network performance of the existing CNIs and the newly developed CNI in this paper, which describes the superiority of the new CNI in terms of the measured network throughput results.
Maintaining Behaviour Driven Development Specifications: Challenges and Opportunities

In Behaviour-Driven Development (BDD) the behaviour of a software system is specified as a set of example interactions with the system using a “Given-WhenThen” structure. These examples are expressed in high level domain-specific terms, and are executable. They thus act both as a specification of the requirements and as tests that can verify whether the current system implementation provides the desired behaviour or not. This approach has many advantages but also presents some problems. When the number of examples grows, BDD specifications can become costly to maintain and extend. Some teams find that parts of the system are effectively frozen due to the challenges of finding and modifying the examples associated with them. We surveyed 75 BDD practitioners from 26 countries to understand the extent of BDD use, its benefits and challenges, and specifically the challenges of maintaining BDD specifications in practice. We found that BDD is in active use in industry, and that the use of domain specific terms, improving communication among stakeholders, the executable nature of BDD specifications, and facilitating comprehension of code intentions are the main benefits of BDD. The results also showed that BDD specifications suffer the same maintenance challenges found in automated test suites generally. We mapped the survey results to the literature, and propose 10 research opportunities in this area.
Open Research

Communication technologies for maintaining close personal relationships are often designed to be lightweight and easy to use. While these properties allow for relationships to be maintained with speed and efficiency, they may come at the expense of more effortful messages that are constructed with thought, time and care. This raises the question of how communication technologies might be designed to provoke moments of effortful maintenance from their users. To explore this question, we designed and implemented Message Builder , a text-based communication system that encourages relational partners to send increasingly long messages. We report findings from a field trial in which 14 dyads used Message Builder for everyday relational maintenance. While some of the effort-provoking features of Message Builder were described as problematic, we found that the system had value in guiding users towards authentic and meaningful effort investments that were valuable within their individual relationships.
Quantitative Assessment on Multiple Timescale Features and Dynamics of Sea Surface Suspended Sediment Concentration Using Remote Sensing Data

Wind-waves, tidal currents and some other dynamic factors dominate the suspended sediment concentration (SSC) variations in shallow seas and it is difficult to quantitatively evaluate the effects of individual dynamic factors on SSC modulation. This work used the long-term Moderate Resolution Imaging Spectroradiometer (MODIS) and the high temporal-resolution Geostationary Ocean Color Imager (GOCI) remote sensing data to quantify the sea surface SSC variations on multiple timescales (intra-tidal, spring-neap, seasonal and long-term timescales) in the Bohai Sea, and further quantitatively evaluated the effects of corresponding dynamic factors on the SSC modulation. The results indicated that the monsoon associated wind-waves and stratification played the most important role in modulating SSC, with seasonal SSC variation of 8.1 mg/L in the Bohai Sea. The intra-tidal current variations played the secondary important role, causing SSC variation of 5.8 mg/L. The spring-neap tidal current variations led to SSC variation of 3.1 mg/L in the Bohai Sea. In the long run (2003-2014), the SSC of the Bohai Sea decreased slightly with SSC variation of 2.8 mg/L (decline rate: 0.23 mg/L/year), which may be caused by the weakening wind, decreasing sediment load from the Yellow River or the massive reclamation in recent decades. Probably due to the topography, sea bed sediment grain size and river plume, SSC variations in the southern Bohai Sea were more pronounced than those in the northern Bohai Sea.
Secondary Structural Analysis of Families of Protein Sequences using Chaos Game Representation

CGR is an effective method for visualizing any structural features if it is given as a sequence of elements [1,2] analyzed by the genomic signature appears as a powerful tool for investigating the mechanisms of DNA maintenance from which the DNA structure results. It would be necessary to understand the patterns they exhibit and to be able to interpret them in a biologically meaningful way [3]. All informational macromolecules of biological interest are linear polymers. The subsequences of a genome exhibit the main characteristics of the whole genome, attesting to the validity of the genomic signature concept [2]. A great extent concentration has newly been focused on analyzing the biological sequences of both Deoxyribo Nucleic Acid (DNA) and proteins using the patterns observed in their graphical representations [1-9] and mathematical descriptions. These studies have shown applications in chemo informatics and bioinformatics. Chaos Game Representation (CGR) for gene (or DNA) sequences was introduced by [4,5] the underlying structures of genome sequences of a few model organisms that were obtained using CGR plots. CGR also offers new possibilities to resolve scale dependencies for information content in sequences [7].
Time-Critical Rendering of Tetrahedral Meshes

Very large irregular-grid volume datasets are typically represented as tetrahedral meshes and require substantial disk I/O and rendering computation. One effective way to reduce this demanding resource requirement is compression. Previous research showed how rendering and decompression of a losslessly compressed irregular-grid dataset can be integrated into a one-pass computation. This work advances the state of the art one step further by showing that a losslessly compressed irregular volume dataset can be simplified while it is being decompressed and that simplification, decompression, and rendering can again be integrated into a pipeline that requires only a single pass through the datasets. In particular, this rendering pipeline can exploit a multi-resolution repre- sentation to maintain interactivity on a given hardware/software platform by automati- cally adjusting the amount of rendering computation that could be afforded, or perform- ing so called time-critical rendering. As a proof of the feasibility of our proposed frame- work, we modify an existing tetrahedral mesh simplification algorithm and integrate it with our previous volume decompression and rendering pipeline. Performance meas- urements on this prototype system show that simplification only adds less than 5% of performance overhead on an average; furthermore, with multi-resolution pre-simplifi- cation the end-to-end rendering delay indeed decreases in an approximately linear fash- ion with respect to the simplification ratio, thus a time-critical rendering of large tetrahe- dral mesh could be achieved.
Influence of Major Geomagnetic Storms Occurred in the Year 2011 On TEC Over Bangalore Station In India

To improve the positional accuracy of Global Positioning System (GPS) and for wide coverage, a satellite Based Augmentation System (SBAS) is being developed in India popularly known as GAGAN. The positional accuracy of GPS is predominantly affected by the ionospheric time delay, which is a function of Total Electron content (TEC). The ionosphere above the Indian subcontinent, which is located near the equatorial region, is highly volatile with large horizontal gradients. Further, major magnetic storms originated from solar bursts can cause strong disturbances in the geo space environment which ultimately affects the performance of Global Navigation Satellite Systems (GNSS). The TEC values at a low latitude station Bangalore (77.510E, 13.030N) India for three major geomagnetic storm events occurred in the year 2011 were presented in this paper and compared with the TEC values obtained from International Reference Ionosphere (IRI) 2007 empirical model. Strong TEC enhancements were observed during the storm days. The results presented in this paper are useful in developing the region specific ionospheric prediction models.
The Effects of Altitudinal Gradients in Botanical Composition and Dry Matter Yield of Herbaceous Species of Natural Grazing Lands of West Shoa, Ethiopia

The study was conducted at Meta Robi district, west Shoa zone of Oromia Regional State in October 2015 with the objectives to assess the effects of altitudinal gradients on grazing lands vegetation patterns with the objectives of assessing the vegetation pattern quantify the biomass yield of the grazing land along with different altitudinal gradients of meta-robi district. The Vegetation assessment was conducted with transect walk with in 4-5kms of in 270 quadrat 90 from each three altitudes having 1mx1m (for herbs layer) quadrant size. The botanical composition was determined by harvesting the herbaceous randomly selected samples (1m × 1m quadrat) within each transect at height of 0–5cm above the ground. Each botanical components were weighed separately to determine the contribution of each component in the total DM yield of the pasture (ILCA 1990). The DM yield of each botanical component in each plot was determined by drying a representative sample in an oven at 70 °C for 48h until constant weight followed by weighing (ILCA, 1990). A total of twenty-four herbaceous species are identified, at the study area. Among them 62.5% were different grasses species, 8.3% were legume species, 25% were forbs or weeds species and 4.2% were sedges. In life form 75% were annuals, while 25% were perennials in life forms. Higher botanical composition of grass species were recorded at lower altitude while higher legumes botanical composition was recorded at upper altitude. The highest dry matter yield of herbaceous species was recorded at lower altitude. Keywords: Botanical composition , dry matter yield, altitudes, Herbaceous species , Grasses and legumes
Investigating the effect of internal gradients on static gradient nuclear magnetic resonance diffusion measurements

ABSTRACTNuclear magnetic resonance (NMR) methods can be used to measure the diffusion coefficient D of fluids. In porous materials, diffusion of the pore fluid is restricted by pore boundaries, such that D may be smaller than the diffusion coefficient of the bulk fluid. This reduction in D provides information about the geometry of the pore space. Significant overestimates of D can, however, occur due to internal gradients caused by magnetic susceptibility contrasts between the pore fluid and the solid phase. We have investigated the way in which internal gradients can impact the measured diffusion coefficient and obscure the link to pore geometry in unconsolidated sediments. We focus on measurements of D obtained with a static gradient diffusion-editing sequence, which can be used with NMR logging tools to measure D in subsurface sediments. Laboratory measurements of D measured with a diffusion-editing D-T2 sequence indicate significant impacts from internal gradients, including D values several orders o.
Non-indicated vitamin B12- and D-testing among Dutch hospital clinicians: a cross-sectional analysis in data registries

Objectives To assess the extent of non-indicated vitamin B12- and D-testing among Dutch clinicians and its variation among hospitals. Design Cross-sectional study using registration data from 2015 to 2019. Participants Patients aged between 18 and 70 years who received a vitamin B12- or D-test. Primary and secondary outcome measures The proportion of non-indicated vitamin B12- and D-testing among Dutch clinicians and its variation between hospitals (n=68) over 2015–2019. Results Between 2015 and 2019, at least 79.0% of all vitamin B12-tests and 82.0% of vitamin D-tests lacked a clear indication. The number of vitamin B12-tests increased by 2.0% over the examined period, while the number of D-tests increased by 12.2%. The proportion of the unexplained variation in non-indicated vitamin B12- and D-tests that can be ascribed to differences between hospitals remained low. Intraclass correlation coefficients ranged between 0.072 and 0.085 and 0.081 and 0.096 for non-indicated vitamin B12- and D-tests, respectively. The included casemix variables patient age, gender, socioeconomic status and hospital size only accounted for a small part of the unexplained variation in non-indicated testing. Additionally, a significant correlation was observed in non-indicated vitamin B12- and D-testing among the included hospitals. Conclusion Hospital clinicians order vitamin B12- and D-tests without a clear indication on a large scale. Only a small proportion of the unexplained variation could be attributed to differences between hospitals.
eGFR Trajectory in LVAD Recipients with Right Heart Failure: Status Quo or a Steady Decline?

wo outcomes particularly dreaded after left ventricular assist device (LVAD) implantation are development of right heart failure (RHF) and worsening kidney function. Yet for better or worse, right heart function and kidney function are innately inter-twined (Figure). Increased venous return, left ventricular (LV) unloading, changes in systemic afterload, intra-operative factors, the effects of chronic heart failure (HF) on right ventricular function, and conformational changes in how ventricles twist as a result of LVAD being sewn into LV can all contribute to the development of postoperative RHF. 1 Chronic kidney disease itself may contribute to the development of RHF via reduced glomerular filtration rate (GFR), tubular dysfunction, renin- angiotensin-aldosterone system activation
Interpretation of Ground Temperature Anomalies in Hydrothermal Discharge Areas

Researchers have long noted the potential for shallow hydrothermal fluids to perturb near‐surface temperatures. Several investigators have made qualitative or semiquantitative use of elevated surface temperatures; for example, in snowfall calorimetry, or for tracing subsurface flow paths. However, a quantitative framework connecting surface temperature observations with conditions in the subsurface is currently lacking. Here, we model an area of shallow subsurface flow at Burgdorf Hot Springs, a rustic commercial resort in the Payette National Forest, north of McCall, ID, USA. We calibrate the model using shallow (0.2 m depth) ground temperature measurements and overburden thickness estimates from seismic refraction studies. The calibrated model predicts negligible loss of heat energy from the laterally migrating fluids at the Burgdorf site, in spite of the fact that thermal anomalies are observed in the unconsolidated near‐surface alluvium. Although elevated near‐surface ground temperatures are commonly assumed to result from locally high heat flux, this conflicts with the small apparent heat loss during lateral flow inferred at the Burgdorf site. We hypothesize an alternative explanation for near‐surface temperature anomalies that is only weakly dependent on heat flux, and more strongly controlled by the Biot number, a dimensionless parameter that compares the rate at which convection carries heat away from the land surface to the rate at which it is supplied by conduction to the interface.
A Method for the Geometric Analysis of Rugose Coral Growth Ridges as Paleoenvironmental Indicators in the Middle Devonian Hungry Hollow Member of Widder Formation, Michigan Basin

Skeletons of Devonian rugose corals feature submillimetre-scale growth ridges on their outer surface (epitheca) that record the successive positions of the coral polyp during longitudinal corallite growth. Specimens of rugose corals Eridophyllum and Cystiphylloides from the Hungry Hollow Member of the Middle Devonian Widder Formation were sectioned longitudinally and imaged by SEM, and image processing techniques were applied to extract a line representing the epithecal surface. Local extrema found through peak detection allowed growth ridges to be represented as simplified triangles, so that geometric measurements (area, length) could be related to coral growth and analyzed in reference to possible paleoenvironmental cycles. This research has produced an objective method for the extraction of growth ridge data from a two-dimensional coral slice, although slice location was found to influence results. Results show potential sub-monthly bundles of ∼15-17 ridges, not previously observed, which suggest a lunar/tidal influence on coral growth.
