The Effects of 5E Inquiring-Based Learning Management on Grade 7 Students’ Science Learning Achievement

The 5E teaching model is presented as an inquiring-based instructional method that benefits learners by letting them construct their knowledge of the class concepts from what they have learned or experienced. The sole purpose of the studies was to compare grade 7 students’ learning achievement of science before and after learning in the learning management plan designed using the 5E inquiry-based learning. The study was conducted in a quasi-experimental design. The participants were 20 grade 7 students in Thailand. They were selected by a purposive random sampling method. The instruments included a 5E inquiring-based learning management plan and a pre-post learning achievement test. The data were analyzed by percentage, mean score, and standard deviation while the study hypothesis was tested using a paired-samples t-test. The results of the study indicate that the implementation of the 5E inquiry-based learning management plan benefits students’ knowledge of heat in a science class. The study provides pedagogical implications as it illustrated how a learning management plan designed in the 5E inquiry-based teaching model affected a science class. It also contributes to the research in the area as it extended the benefits of the teaching model in teaching concepts of science.
Measuring the Impact of a Shared Vision on the Perceived Meaningfulness

In this paper we describe an approach to assess the impact that a shared vision has on the perceived meaningfulness of work in an organization. Our measurement system is based on the essential principles of performance measurement. Building on this assessment logic, we present the process and respective scales that allow us to measure changes in perceived meaningfulness that occur through a shared vision development process. With this work, we provide a practically applicable measure to evaluate whether the creation of a shared vision is beneficial for an organization.
A Human Gait Tracking System Using Dual Foot-Mounted IMU and Multiple 2D LiDARs

This paper proposes a human gait tracking system using a dual foot-mounted IMU and multiple 2D LiDARs. The combining system aims to overcome the disadvantages of each single sensor system (the short tracking range of the single 2D LiDAR and the drift errors of the IMU system). The LiDARs act as anchors to mitigate the errors of an inertial navigation algorithm. In our system, two 2D LiDARs are used. LiDAR 1 is placed around the starting point, and LiDAR 2 is placed at the ending point (in straight walking) or at the turning point (in rectangular path walking). Using the LiDAR 1, we can estimate the initial headings and positions of each IMU without any calibration process. We also propose a method to calibrate two LiDARs that are placed far apart. Then, the measurement from two LiDARs can be combined in a Kalman filter and the smoother algorithm to correct the two estimated feet trajectories. If straight walking is detected, we update the current stride heading and the foot position using the previous stride headings. Then, it is used as a measurement update in the Kalman filter. In the smoother algorithm, a step width constraint is used as a measurement update. We evaluate the stride length estimation through a straight walking experiment along a corridor. The root mean square errors compared with an optical tracking system are less than 3 cm. The performance of proposed method is also verified with a rectangular path walking experiment.
The Hubble Space Telescope Key Project on the Extragalactic Distance Scale. XVII. The Cepheid Distance to NGC 4725

The distance to NGC 4725 has been derived from Cepheid variables as part of the Hubble Space Telescope Key Project on the Extragalactic Distance Scale. Thirteen F555W (V) and four F814W (I) epochs of cosmic-ray-split Wide Field and Planetary Camera 2 observations were obtained. Twenty Cepheids were discovered, with periods ranging from 12 to 49 days. Adopting a Large Magellanic Cloud distance modulus and extinction of 18.50 ± 0.10 mag and E(V-I)=0.13 mag, respectively, a true reddening-corrected distance modulus (based on an analysis employing the ALLFRAME software package) of 30.50 ± 0.16 (random) ± 0.17(systematic) mag was determined for NGC 4725. The corresponding of distance of 12.6 ± 1.0 (random) ± 1.0 (systematic) Mpc is in excellent agreement with that found with an independent analysis based upon the DoPHOT photometry package. With a foreground reddening of only E(V-I)=0.02, the inferred intrinsic reddening of this field in NGC 4725, E(V-I)=0.19, makes it one of the most highly reddened fields encountered by the HST Key Project to date.
Implementation of Micro Usb Charger TP4056 and Battery Indicator LED in Portable Solar Charge

Mobile is a communication tool that is needed in today's era of globalization. The source of the cellphone's power is the battery which if the power goes out and the battery runs out, it is necessary to charge the battery to turn it back on. In this study, a portable solar panel-based charger was designed as an alternative to charging batteries without using a power source. The method used is research and development where this research produces a product. The results obtained indicate that the highest intensity value at 11:00 WIB is 5986 cd, the highest current value before entering the current stabilizer and voltage amplifier circuit is 0.004 A and the highest voltage is 5 V, for the current value after entering the current stabilizer and amplifier circuit. the overall voltage value is the same, namely 0.002A and 4V. This simple portable solar cell phone charger is able to supply power to the Nokia 215 Dual SIM for 5 hours and 30 minutes. There is an LED indicator on the portable solar charger where during the charging process it will be red, then after it is full it will be blue, and when it is running out it will be orange. ©2018 JNSMR UIN Walisongo.

Evolution of the Coordination of Activities Aimed at Building Knowledge in the Wikipedia Community

The first decade of the 21st century spawned the intense development of online communities of practice. The largest knowledge-sharing communities were formed in several dozen language versions of Wikipedia. Defining rules for cooperation was necessary to ensure the desired content quality created by Wikipedians. It was essential to develop the appropriate initiatives, tools, and space for effective activity coordination within the service. Previous research in this area pointed to the role of leadership, group size, and tools facilitating work automation in creating actionable strategies and in the self-organization of work. This paper aims to characterize the variability in creating new concepts of cooperation in selected language versions of Wikipedia and identify the factors of participating in various forms of cooperation. The author assumes that the greater number of initiatives a user enters contributes to an increase in their overall activity. The research conducted was both qualitative and quantitative. A netnographic approach was used, as well as a statistical analysis of user activity records. Thanks to the netnographic research, the stages of Wikipedia’s evolution were identified. Quantitative research has shown a correlation between the number of activity areas (a user’s affiliation to WikiProjects) and their overall activity (the number of edits made). A change in Wikipedians’ activity style was also observed depending on their seniority on the website. The study’s conclusions may be helpful for organizations using crowdsourcing to achieve their own goals.
Scalable Fuzzy Systems

– In this paper a new class of fuzzy systems called scalable fuzzy (SF) systems are proposed. The SF design is built upon the idea of extending the conventional fuzzy logic approach to linguistic variables to all numbers. This leads to a new set of infinite continuous rule-base and membership functions which are located on all rational numbers and are defined based on scale, position, and input variables. The consequent of rules in the Takagi-Sugeno form are then modified, and a mathematical solution based on the convolution theorem is employed for SF modeling purposes. The discrete form of SF systems is developed, and its application is exemplified using several case studies.
A simulation study with different number of observation using nonparametric regression splines

In this study we made a simulation study using various nonparametric techniques. The methods that we have used in this study are following: regression spline, penalized spline, and their Bayesian versions: adaptive Bayesian regression spline and Bayesian P-splines. The main goal of our study is to compare nonparametric regression techniques and Bayesian versions of these techniques. For this purpose we made a simulation study with different functions. For each function we sampled n = 50, n = 100 n = 200 n = 400 number of observations. The purpose of using different number of sampled observations is to analyze the behavior of utilized techniques. For simulation study we used dataset which sampled from the functions in the paper of [7]. The results of simulation study are compared with each other using mean value of the MSE (mean squared error) and showed results graphically using box plot of MSE.
Simple Discontinuous Pulse-Width Modulation Scheme for the Loss Reduction of a Dual Inverter Fed an Open-End Winding Induction Motor

This paper presents a simple discontinuous pulse width modulation (DPWM) switching scheme to reduce the switching loss of a single DC-link dual two-level inverter fed an open-end winding (OW) induction motor (IM). The dual inverter system is attractive in many applications due to higher DC-link voltage utilization. Additionally, the OW motor has the potential fault-tolerant capability. However, the use of the dual inverter results in reduced system efficiency due to increased power losses in the inverter. Moreover, an OW motor inherently suffers from a zero-sequence current (ZSC) issue because the open neutral point of the stator windings provides the ZSC path. The ZSC causes negative effects in the system, such as an additional power loss and total harmonic distortion (THD). Thus, this work proposes an optimal DPWM scheme to reduce the inverter loss while suppressing the ZSC. Additionally, this work proposes a strategy to make the average power loss of each inverter equal. The performance of the proposed method is discussed in terms of switching power loss reduction and ZSC suppression. Simulation and experimental results are provided to verify the effectiveness of the proposed DPWM scheme.
The Application of PLS-SEM in Knowledge Management Processes in Higher Education Institutions

This paper aims to investigate knowledge management (KM) processes in higher education institutions and shed light on the factors that influence the dynamics behind these processes. We focused on understanding how the perceptions about the involvement in KM activities can influence two of the knowledge management skills defined in the literature: absorptive capacity and desorptive capacity. Our work is based on the Theory of Planned Behaviour because it has the power to analyse and explain, through its constructs (attitude, subjective norm, perceived behavioural control), the attitudes of individuals and their perceptions about the implementation of a particular behaviour. The methodology adopted for the empirical investigation is PLS-SEM (Partial Least Squares -Structural Equation Model). The necessary data was collected through a questionnaire sent by email to the potential academics interviewed. The results suggest that the factor impacting the relationship between KM and absorptive and desorptive capacity processes is the behavioural control perceived by academics. In addition, they demonstrate that the organizational climate within the university is an essential predictor of the behavioural intention of academics. The limitations, including the limited number of respondents and suggestions for future developments, are the conduction of a multi-group analysis and building a second-order PLS (Partial least square) model.
A Proposed Method to Acquire More Geometric Features from Hand-Drawn Sketches

: We introduce a novel method for learning geometric features of hand-drawn sketches. The method is based on two models: the first depends on a newly-designed algorithm based on the Decision Tree (DT) technique; while the other is based on the Feed-forward Neural Network (FNN) technique. Each model consists of training and testing phase, we extract features of object and build the knowledge base in training phase. In testing phase, we test the learning ability to appear advantages of using DT with new objects and FNN with large data. The results of our method show desirable performance in learning. Experiments on TU-Berlin, QuickDraw, and our own dataset reveal the effectiveness of the method. We achieve learning accuracy 99.98% on our own dataset, 98.07% on TU-Berlin, and 96.69% on QuickDraw. Experiments signify that geometric feature representation and manipulation by our method brings about a substantial improvement over state-of-the-art methods on sketch classification.
Particulate Matter in the Korea Train eXpress (KTX) Cabin and its Exposure

This study aims to assess the particulate matter (PM1, PM2.5, PM10) and black carbon (BC) in the Korea Train eXpress (KTX) cabin during train running, and the personal exposure of PM2.5 for the female/male passengers who use the KTX 20 days a month to commute. Intensive measurements were made on the day when the outside ambient PM concentration was much higher than usual. To compare with the PM concentration in the subway cabin, a measurement was also performed in some sections of the Seoul Metro subway (from Namyoung Station (hereafter referred to as the “Sta.”) to Jonggak Sta. ). The amount of PM2.5 exposure was calculated for the male/female passengers who regularly board the KTX. The , which is the amount of PM2.5 exposure when moving by car in the same section, was also calculated. The PM concentration in the KTX cabin elevated and fallen off at train staying and train running, respectively. The PM2.5 concentrations inside KTX cabin at the stop station exhibited a remarkable positive correlation with those of outdoor. Compared to the PM concentration measured in the cabin of Seoul Metro subway, PM1, PM2.5, and PM10 in the KTX passenger cabin were 74.9%, 73.3%, and 62.7% of those in the cabin of Seoul Metro subway, respectively. The PM2.5 exposure amount (exposure PM2.5 (μg)) when moving the same section using the KTX and passenger cars was calculated, and as a result, the exposure PM2.5 (μg) for both male and female were 5.7 times lower in the KTX than that in car. The mapping result of BC concentration drawn on the KTX line from Iksan Sta. to Gwang-myeong Sta. shows that it fluctuated greatly for each service section or stop station.
Association between bile area in the duodenal bulb and abdominal symptoms: Quantitative analysis using blue laser imaging

Bile acids are strongly associated with the pathogenesis of functional gastrointestinal diseases. In recent years, blue laser imaging (BLI) endoscopy has emerged as a novel image-enhanced endoscopic method, which illustrates bile as a reddish hue. The present study investigated the factors that affect the area of bile in duodenal bulbs using BLI. For this purpose, patients (356 cases) who underwent upper endoscopy with BLI between April, 2017 and December, 2019, and completed patient background and symptom questionnaires [Constipation Scoring System (CSS), Bristol Stool Form Scale (BSFS) and Frequency Scale for Symptoms of gastroesophageal reflux disease (FSSG)], were retrospectively investigated. Each BLI bile score was calculated as a percentage of bile area in a field of view in the duodenal bulb using a KS400 image analysis system, and the association with abdominal symptoms was examined using multiple regression analysis. The patient characteristics included the following: Age (in years), 69.9±11.3; male/female ratio, 146/210; body mass index, 23.0±3.8; reflux esophagitis (M/A/B/C), 143/19/3/3; atrophic gastritis (C-0/C1-3/O1-3), 132/100/124; proton pump inhibitor potassium competitive acid blocker/aspirin/ursodeoxycholic acid/gall bladder stones/cholecystectomy, 105/27/18/43/18; BLI bile score, 7.10 (±14.34); CSS score, 3.55 (±3.80); BSFS score, 3.91 (±1.02); and FSSG score, 4.80 (±5.76). Correlation coefficients (P<0.05) for the BLI bile score were found for cholecystectomy (Rho=0.137) and aspirin use (Rho=0.118). In multiple regression analysis, independent predictors of the BLI bile score were cholecystectomy [standardized partial regression coefficient (β)=0.169, P=0.001] and the BSFS score (β=0.107, P=0.042). On the whole, the present study demonstrates that the duodenal bile area in BLI upper endoscopy is associated with cholecystectomy and fecal characteristics.
Beyond the Network Border: The Emergence of Regional “Meta-Networks” and Their Effects on Dutch Public-Policy Projects

Although network research typically examines whole networks, interorganizational networks are not isolated entities. This study focuses on overlapping regional networks that emerge as an unintentional result of an amalgamation of central governmental projects. We use archival, interview, and social network data and visualize the normally imperceptible meta-networks. Large and centralized meta-networks are found to stimulate goal attainment, while smaller, decentralized meta-networks have higher-quality relations. Both funders and network members who co-implement public projects should make good use of regional meta-networks. Therefore, future research on the determinants of successful decentralized projects should include the dynamics and effects of meta-networks.
Thriving, Persisting, or Agonizing: Integrated Math Anxiety Experiences of University Students in Introductory Geoscience Classes

Many factors may contribute to women being underrepresented and marginalized in college-level geoscience majors. Limited research has examined students’ math anxiety as a possible factor. To address the dearth of research, we conducted a qualitative study to explore the math anxiety experiences held by students in college-level geoscience classes. Through analysis of students’ written math narratives, we identified three themes capturing students’ integrated math anxiety experiences (IMAEs), which integrated students’ feelings, physiological reactions, and thoughts. Students with Thriving IMAEs liked math and had positive assessments of themselves in math. Students with Agonizing IMAEs had negative feelings and thoughts about math and experienced negative physiological reactions. Students with Persisting IMAEs had positive and negative feelings and thoughts, but thought that, ultimately, they could persist in math. A higher percentage of women than men held Agonizing IMAEs, and a lower percentage of women than men held Thriving IMAEs. Students in introductory geoscience classes had a range of IMAEs, which may have an important role in their success in class and in their decisions to take additional geoscience classes.
Regulation of Anthocyanin Biosynthesis by Drought and UV-B Radiation in Wild Tomato (Solanum peruvianum) Fruit

Anthocyanins are plant pigments derived from the phenylpropanoid pathway which are produced in many different species, contributing to defense against stresses by their antioxidant properties. Cultivated tomatoes cannot synthesize flavonoids; however, wild tomatoes such as Solanum chilense and Solanum lycopersicoides have anthocyanin pigmented skin. Other wild tomato species such as Solanum peruvianum have been poorly studied concerning anthocyanin accumulation in the fruit. This research is the first to address the regulation of anthocyanin biosynthesis mediated by drought stress and light radiation in S. peruvianum fruit. Transcript accumulation of SpAN2, encoding for a key MYB type transcription factor for the regulation of anthocyanin biosynthesis, was induced in the fruit of plants exposed to drought treatment. In addition, fruit peel accumulates a greater anthocyanin content in water deficit-treated plants. The expression of SpAN2 was also regulated according to sunlight exposure, reaching a higher expression during maximal daily UV radiation and under controlled UV-B treatments. Similar results were observed for the expression of the late flavonoid biosynthetic gene dihydroflavonol 4-reductase (SpDFR). These results suggest that SpAN2 and SpDFR are involved in anthocyanin biosynthesis under drought stress and UV radiation in S. peruvianum.
Population status, habitat preference and distribution of Bristled Grassbird Chaetornis striata in Bangladesh

Summary The little-known Bristled Grassbird Chaetornis striata is thought to be declining due to the loss of grassland habitats throughout its range, and is currently classified as globally ‘Vulnerable’. In order to investigate the current status and possible causes of the presumed decline, we assessed population density of Bristled Grassbird in Padma and Jamuna river systems of Bangladesh. The study was conducted during the breeding seasons of the Bristled Grassbird in April and May in 2016–2019, using distance sampling and habitat suitability modelling. We also examined habitat preferences and responses to environmental changes based on vegetation structure and habitat modifications at point count locations. We detected a total of 39 birds with a mean group size of 1.44 individuals. We estimated 4.52 (95% CI: 2.65–7.73) individuals per km2 with an encounter rate of 1.48 detections per point count station and 341.15 birds within the study area. Our habitat suitability model projected a total of 167.41 km2 of suitable habitat and a total of 756.7 birds in floodplain grasslands of Padma and Jamuna river systems. The Bristled Grassbird was positively associated with grass height and grass density with 92.31% of 39 detections at Saccharum spontaneum dominated grasslands. We did not find a significant effect on Bristled Grassbird detections with increasing human activities, although the detection rate decreased linearly with increasing agricultural intervention and grass harvesting. These findings indicate that the Bristled Grassbird is more widely distributed throughout Bangladesh, and may be less vulnerable to grassland modifications, than previously thought.
