Published: July 2023

INTRODUCTION:

High-quality colonoscopy is paramount for colorectal cancer prevention. Since 2009, endoscopists at our institution have received quarterly report cards summarizing individual colonoscopy quality indicators. We have previously shown that implementing this intervention was associated with short-term improvement in adenoma detection rate (ADR). However, the long-term effect of continued monitoring on colonoscopy quality is unclear.

METHODS:

We conducted a retrospective study of prospectively administered quarterly colonoscopy quality report cards at the Roudebush Veteran's Affairs Medical Center between April 1, 2012, and August 31, 2019. The anonymized reports included individual endoscopists' ADRs, cecal intubation rates, and withdrawal times. Analyses were performed to determine slopes over time for each quality metric by physician and assess for differences based on whether ADRs were calculated quarterly or yearly.

RESULTS:

Data from the report cards of 17 endoscopists who had performed 24,361 colonoscopies were included. The mean quarterly ADR (±SD) was 51.7% (±11.7%) and mean yearly ADR was 47.2% (±13.8%). There was a small increase in overall ADR based on quarterly and yearly measurements (slope + 0.6%, P = 0.02; and slope +2.7%, P < 0.001, respectively), but no significant change in individual ADRs, cecal intubation rates, or withdrawal times. Analysis of SD of ADRs showed no significant difference between yearly and quarterly measurements (P = 0.064). Individual endoscopists' ADR SD differences between yearly and quarterly measurements ranged from −4.7% to +6.8%.

DISCUSSION:

Long-term colonoscopy quality monitoring paralleled stable improvements in overall ADR. For endoscopists with baseline high ADR, frequent monitoring and reporting of colonoscopy quality metrics may not be necessary.

Indonesia implemented a nickel ore export ban policy in 2014 with the aim of maintaining sovereignty and control over natural resources, increasing the added value of nickel products, and optimally utilizing nickel wealth to improve people's welfare and strengthen the country's economy. This policy was also taken to strengthen Indonesia's bargaining position in global trade and to show independence and courage in making decisions that could provide long-term benefits for the country. From the perspective of rational choice theory, the nickel ore export ban policy is the result of considering ideological preferences, which focus on efforts to produce nickel derivative products that are processed from upstream to downstream in Indonesia which can then increase the added value of nickel products in the international market which has an impact on creating economic independence from the nickel industry. The nickel ore export ban policy also aims to strengthen Indonesia's bargaining position in international politics and global trade, especially through nickel diplomacy.

Published: July 2023

Diponegoro University Property (BMU) requires an inventory process by the assets and logistics division at least once every five years. The inventory process is still manually. So it is necessary to develop an Integrated Asset Management Information System Inventory Module. The development of an information system that used the Big Bang and Use Case Points method, in this study the Agile method with Scrum Framework will be implemented based on considerations. Scrum as a framework that implements Sprints to break down complexity and accommodate priority features that need to be built from an information system, also divides the roles in implementing development into Product Owner, Developer Team and Scrum Master. The results of implementing this method can be a solution to several problems that arise during development, that is : dividing roles with existing teams, accepting all updates and changes originating from user evaluations through mutual agreement, work transparency which can be a reference in assigning the workload of each team members, regular periodic inspections to remind each member of development targets and goals, as well as adapt to implementing conditions, especially in adjusting communication and implementation times. So make information system development time can implemented shorter.

Published: July 2023

Improving quality, enhancing productivity, redesigning machining tools, eliminating waste in production, and shortening lead time are all objectives aimed at improving customer satisfaction and increasing profitability for manufacturing companies. This study combines lean manufacturing and six sigma techniques to form a technique called Lean Six Sigma (LSS) by using the DMAIC (Define-Measure-Analysis-Improve-Control) model. This study proposes to use statistical test models to analyze real data collected directly from the operator. The study proposes to use the Taguchi optimization technique to determine the optimal conditions for oil dipping tanks of molybdenum materials. In addition, the study also proposes a computer vision technique to recognize objects using color recognition techniques running on the LABVIEW software platform. This study builds a digital numerical control (DNC) model operating on digital signal processing techniques, linking the data of each process together. The results reduced the rate of defective parts in the whole processing stage from 6.5 % to zero defects, the whole processing line production capacity increased by 7.9 %, and the profit of the whole production line was USD 35762 per year. As a valuable external outcome, the conclusion of the LSS project fostered a spirit of continuous improvement. The utilization of research results from the research environment in the actual production setting is significantly enhanced for the operator. The LSS model is deployed with specific tasks and targets for each member of the LSS project team, and the processing conditions for each specific stage are optimized, such as the oil dipping process and hole grinding process. Industry 4.0 techniques, including computer vision, digital numerical control, and commercial software such as LabVIEW and MINITAB, are optimized for use, simplifying machining operations. Some proposed directions for future research are also presented in detail. For example, studying the improvement of the quality of the 220 V power supply through harmonic mitigation in processing factories is an intriguing area of investigation. Additionally, exploring data security for big data in the context of Industry 4.0 would be a valuable study to enhance customer satisfaction with big data technology in the future.

Authors: van Erp T. , Rytter N.G.M.
Published: July 2023

Manufacturing companies are facing what recently has been called the Twin Transition. They must conduct a digital transition as well as a transition from mere linear toward more circular value creation. The research presents an integrated Design and Operations Framework for digital and circular manufacturing systems. Defined process phases of the framework are described which address: the maturity assessment, Objectives and Key Results, the design (Des) and operations (Ops) of the manufacturing system, and a training concept. The authors follow a qualitative research approach for developing the integrated DesOps Framework for Circular and Digital Manufacturing Systems. The framework is conceptualized by combining state-of-the-art procedures and methods in the field of maturity and readiness assessment, Objectives and Key Results, Systems Engineering, and DesOps. Eventually, a case study is utilized for verifying the principal efficacy of the conceptualized framework. The research intends to scientifically contribute to the field of manufacturing systems design by proposing a novel design framework. From industrial application perspective, the research intends to contribute to improving decision-making in manufacturing companies by providing them with a practical-oriented guideline for transforming their manufacturing systems in the sense of the Twin Transition.

Authors: Malone Laura A. , Hill Nayo M. , Tripp Haley , Wolpert Daniel M. , Bastian Amy J.
Published: July 2023

Here we designed a motor adaptation video game that could be played remotely (at home) through a web browser. This required the child to adapt to a visuomotor rotation between their hand movement and a ball displayed in the game. The task had several novel features, specifically designed to allow the study of the developmental trajectory of adaptation across a wide range of ages. We test the concurrent validity by comparing children's performance on our remote task to the same task performed in the laboratory. All participants remained engaged and completed the task. We quantified feedforward and feedback control during this task. Feedforward control, a key measure of adaptation, was similar at home and in the laboratory. All children could successfully use feedback control to guide the ball to a target. Traditionally, motor learning studies are performed in a laboratory to obtain high quality kinematic data. However, here we demonstrate concurrent validity of kinematic behavior when conducted at home. Our online platform provides the flexibility and ease of collecting data that will enable future studies with large sample sizes, longitudinal experiments, and the study of children with rare diseases.
Experimental investigation of electrode wear assessment in the EDM process using image processing technique
Authors: Khleif Ali Abbar
Published: July 2023

One of the widespread non-traditional and non-contact machining processes is the electrical discharge machining (EDM) process, which depends on removing material from the surface by different repeat electrical discharges between a machined workpiece and a cutting tool called the electrode. The electrode wear in the EDM process is one of the parameters of significant technological interest. This article proposed a reliable image-based system that automatically detects and computes electrode wear in EDM of rectangular steel workpiece plate of AISI 314 using a copper electrode with a rectangular shape. MATLAB environment and image processing toolbox are used to identify and manipulate the captured rectangular electrode image for rectangular electrode data extraction needed for the electrode wear identification process. The results show that the proposed image-based approach, using a non-contact measuring system and relatively inexpensive equipment, is suitable with good accuracy and efficiency for measuring and testing electrode wear.

Four energetic binders, polyglycidyl nitrate (PGN), poly(3-nitratomethyl-3-methyloxetane) (PNIMMO), poly(bis(azidomethyl)oxetane) (PBAMO), and glycidyl azide polymer (GAP) were, respectively, mixed with dihydroxylammonium 5,5′-bistetrazole-1,1′-diolate (TKX-50), forming TKX-50-based polymer bonded explosives (PBXs). Interfacial forces (binding energies) under different temperatures, mechanical properties (tensile modulus, bulk modulus, shear modulus, and Poisson’s ratio), and moldability of TKX-50-based PBXs were investigated by employing molecular dynamics simulation, the energy characteristics of TKX-50-based PBXs were calculated by Chapman–Jouguet (C–J) detonated theory. Results show that temperature has little effect on the binding energies, but the binding energies between every energetic binder and each surface of TKX-50 are different and the order of combined ability between four energetic binders and TKX-50 decrease as follows: PNIMMO > PBAMO > PGN > GAP. Compared with TKX-50, the addition of four energetic binders makes the rigidity of TKX-50-based PBXs decrease and the plasticity improve, the plastic ability rank is in the order of PGN > PNIMMO > PBAMO > GAP. In addition, the moldability of TKX-50-based PBXs is obviously improved, the increasing order is PGN > PNIMMO > PBAMO > GAP. Finally, the detonation performances indicate that compared with common binder, the addition of the energetic binder makes TKX-50-based PBXs have higher energy under the same condition.
Review on optical solitons for long haul transmission
Authors: Kaur Paramjit , Dhawan Divya , Gupta Neena
Published: July 2023

Fiber optics telecommunication is the currently established backbone infrastructure for most of the information flow across the world. New services and applications are causing an exponential increase in Internet traffic, increasing transmission rate, and high bandwidth-demanding applications have been propelling the data rate per wavelength to approach the speed limit of electronics. In a few years, the current fiber optic communication system infrastructure will not be able to meet this demand because fiber nonlinearity dramatically limits the information transmission rate. Also, the dispersion phenomenon is a problem for high bit rates and long-haul optical communication systems. An easy solution to this problem is optical solitons pulses that preserve their shape over long distances. An optical soliton is formed by balancing nonlinearity (self-phase modulation) and dispersion phenomenon (group velocity dispersion). In this review article, a detailed study of optical solitons is presented along with its recent progress. Advanced numerical methods such as Darboux transform (DT), digital back propagation, split step Fourier, and forward–backward methods are also discussed in this paper which is used for solving higher-order solitons.
Evaluating the influence of radial power heterogeneity of fuel rod on its temperature in an accelerator driven subcritical system
Authors: Yu Rui , Wang Guan , Jiang Wei , Yao Cunfeng , Zhang Lu , Gu Long
Published: July 2023

The radial non-uniformity of an ADS fuel rod power density on the peak plane is as high as 10.46 %, which is derived from the reactor physics calculations. In order to investigate the influence of the above-mentioned radial power inhomogeneity on the fuel temperature distribution, this paper constructs a set of two-dimensional comparison examples, where one example uses a uniform heat source and another uses a non-uniform heat source distribution, with taking the fuel segment and its corresponding cladding segment in the region where the peak plane is located as the research object. The finite element software COMSOL is used to conduct the heat transfer analysis. The results of the study show that the fuel temperature under radial non-uniform power distribution is almost the same as that under uniform power. Therefore, this radial non-uniformity can be completely ignored when the research object of temperature is considered. The quantitative calculation carried out in this research can provide certain data support for the engineering research of accelerator driven subcritical system, and can also provide certain guidance for the performance analysis of such fuel elements.

Published: July 2023

Iron-overload-associated cardiomyopathy has been one of the primary causes of mortality in thalassemia patients with iron burden. There is growing evidence citing the beneficial effects of ebselen as an antioxidant selectively blocking the divalent metal transporter 1 (DMT-1) to deter iron ingress into cardiomyocytes, raising internets in viewing this component in this population in order to treat and even prevent cardiomyopathy occurring from iron surplus. In this article, we reviewed the potential advantageous effects of ebselen in thalassemia patients who suffer from iron excess, susceptible to cardiomyopathy induced by iron overload. A systematic search in several databases, including PubMed, Scopus, and Web of Science, was conducted to explore the role of ebselen in controlling iron-overload-related cardiomyopathy in thalassemia patients by the keywords of Ebselen AND iron. The inclusion criteria were English-written preclinical and clinical studies investigating the efficacy and side effects of ebselen in an iron-overload context. After searching the databases, 44 articles were found. Next, of 19 published articles, 3 were included in this article. After reviewing the references of the included studies, no articles were added. In conclusion ebselen can be a promising adjuvant therapy in patients with thalassemia alongside the standard treatment with iron chelators, particularly in severe cases with cardiomyopathy, due to falling iron inflow by inhibiting DMT-1 and increasing ferroportin-1 expression and antioxidant properties. However, clinical studies need to be carried out to reach a definite conclusion.
The Classification of Q1 SJR-Ranked Library and Information Science Journals by an AI-driven “Suspected Predatory” Journal Classifier
Authors: Teixeira da Silva Jaime A.
Published: July 2023

In academic publishing, there is a need to be able to discern scholarly from unscholarly, deceptive, and/or predatory journals. Predatory journals are not expected among highly ranked journals in reputable databases. SCImago Journal Rank (SJR), which ranks journals into four quartiles (Q1–Q4), acts as a whitelist or safelist for journal selection. Q1 SJR-ranked journals are likely not “predatory.” An artificial intelligence (AI)-based tool Academic Journal Predatory Checking (AJPC) system launched in February 2023 claims to differentiate suspected predatory journals (SPJs) from normal journals. AJPC system classified, in a 2 June 2023 assessment, 27 (or 42%) of the 64 Q1 SJR-ranked library and information science journals, most (48%) published by Taylor & Francis, as SPJs. This output is unlikely to be accurate (or is likely to be inaccurate) and may suggest that this free online AI-driven tool, whose output can be independently verified by anybody, may be providing erroneous output, and thus misleading information.
La liberté à corps perdu

Published: July 2023

La liberté a été assez largement réduite, dans la modernité occidentale, à une occurrence individualiste. C’est la liberté de l’individu « face au monde » et eu égard aux autres dont il s’agit surtout. Notre propos consistera en une critique de cette idée, au profit d’une compréhension relationnelle de la liberté. Il apparaîtra que nous avons besoin de soutien mutuel pour être et rester libre et que, à l’heure de l’Anthropocène, c’est la Terre qui nous soutient qui a elle aussi besoin de toute notre attention, sans quoi les conditions de la liberté pourraient être très compromises.
Research on WPD and DBSCAN-L-ISOMAP for circuit fault feature extraction
Authors: Zhang Yu , Cheng Zhonghua , Lian Guangyao , Dong Enzhi , Wu Zhenghao , Zhao Runze
Published: July 2023

To solve the problem of feature extraction in electronic circuits due to the nonstationary and nonlinear characteristics of fault signals, a fault feature extraction method for electronic circuits is proposed, which combines wavelet packet analysis and an improved landmark ISOMAP mapping algorithm. The wavelet packet technology is used to decompose and reconstruct the fault feature signals at multiple levels. The extracted wavelet entropy is used to construct the feature vector matrix. The density-based spatial clustering of applications with noise (DBSCAN) clustering algorithm is used to calculate and screen the landmark points. The improved landmark ISOMAP is used to embed the high-dimensional fault feature parameter set into the low-dimensional eigenspace, extract the low-dimensional and sensitive fault feature subset, and apply the support vector machine to identify the fault. The fault diagnosis experiment of the three-phase VIENNA rectifier shows that compared with the principal component analysis method, the traditional ISOMAP method, and the landmark ISOMAP method, the landmark ISOMAP method based on DBSCAN clustering algorithm extracts the fault signal characteristics of electronic equipment more easily.
Die Wirkung der Gaspreisbremse auf Inflation und fiskalische Kosten: eine Abschätzung
Authors: Garnadt Niklas , Nöh Lukas , Salzmann Leonard , Schaffranka Claudia
Published: July 2023

Kann die Gaspreisbremse die Inflation wirksam dämpfen? Welche fiskalischen Kosten wirft ihr Einsatz auf? Antworten auf diese Fragen sind wichtig für die Finanzplanung des Bundes sowie für geldpolitische Entscheidungen. Doch die seit dem Jahr 2021 sehr hohe Volatilität der Spot- und Futures-Preise im Energiegroßhandel sowie die spärlichen Informationen über die Überwälzung der Großhandelspreise auf die Endkundenpreise erschweren präzise Schätzungen. Insbesondere stehen kaum öffentliche Informationen über die Vertragsstruktur der Endkunden sowie die Beschaffungsstrategien der Versorgungsunternehmen zur Verfügung. Um die möglichen Inflationseffekte sowie die fiskalischen Kosten der Gaspreisbremse abzuschätzen, treffen wir eine Reihe konkreter Annahmen über die Beschaffungsstrategien und die Vertragsstruktur. Es zeigt sich, dass der Einsatz der Gaspreisbremse die Inflation im Jahr 2023 um 0,25 bis 0,4 Prozentpunkte dämpfen könnte. Bei den fiskalischen Wirkungen ergeben sich für das Jahr 2023 Kosten von rund 15 Milliarden Euro.
Role of the basal ganglia in innate and learned behavioural sequences
Authors: Favila Natalia , Gurney Kevin , Overton Paul G.
Published: July 2023

Integrating individual actions into coherent, organised behavioural units, a process called chunking, is a fundamental, evolutionarily conserved process that renders actions automatic. In vertebrates, evidence points to the basal ganglia – a complex network believed to be involved in action selection – as a key component of action sequence encoding, although the underlying mechanisms are only just beginning to be understood. Central pattern generators control many innate automatic behavioural sequences that form some of the most basic behaviours in an animal’s repertoire, and in vertebrates, brainstem and spinal pattern generators are under the control of higher order structures such as the basal ganglia. Evidence suggests that the basal ganglia play a crucial role in the concatenation of simpler behaviours into more complex chunks, in the context of innate behavioural sequences such as chain grooming in rats, as well as sequences in which innate capabilities and learning interact such as birdsong, and sequences that are learned from scratch, such as lever press sequences in operant behaviour. It has been proposed that the role of the striatum, the largest input structure of the basal ganglia, might lie in selecting and allowing the relevant central pattern generators to gain access to the motor system in the correct order, while inhibiting other behaviours. As behaviours become more complex and flexible, the pattern generators seem to become more dependent on descending signals. Indeed, during learning, the striatum itself may adopt the functional characteristics of a higher order pattern generator, facilitated at the microcircuit level by striatal neuropeptides.
Laboratory Small-Strain Stiffness Measurement Using Distributed Acoustic Sensing
Authors: Niu Yanlong , Chian Siau Chen , Li Yunyue Elita , Fang Gang
Published: July 2023

This article introduces a novel method for measuring the small-strain stiffness of materials at the laboratory scale using the emerging technology of distributed acoustic sensing (DAS). This setup involves modifying the traditional free-free resonant column test by wrapping the DAS fiber optic cable around the sample. Tests are conducted using both active and passive sources. Sample resonances measured by DAS demonstrate a high degree of consistency with conventional accelerometer, indicating that DAS is accurate and reliable at the kilohertz scale. To extract the sample resonant frequency from passive sources in laboratory environments (such as cooling fan noise, mixer vibrations, and manual tamping procedure), the auto-correlation method is employed to enhance the amplitude spectrum’s signal-to-noise ratio. The measured transverse resonance excited by passive sources aligns well with that measured under active sources, suggesting the potential for using nonstationary ambient vibrations for long-term monitoring. The study also reveals that impulse-like forces are more suitable for exciting distinguishable resonant frequency compared to continuous but weak ambient vibrations. In a benchmark study, the repeatability of DAS measurements is verified using fabricated samples with known and stable stiffness. The measured constrained and shear moduli are found to be consistent among DAS, accelerometer, and ground-truth values, confirming the robustness and accuracy of the DAS-based free-free resonance column test. To further demonstrate the practical application of the proposed DAS-based system, a 28-day monitoring of cement-stabilized soil is conducted. The small-strain stiffness evolution is successfully captured by DAS, with marginal differences between measurements under active and passive sources. This outcome highlights the potential quality assurance scenarios for DAS because of its distributed properties and rapid data acquisition capabilities.
Characteristics of the Barthel Scale in Terms of Neurological Care
Authors: Filipska-Blejder Karolina , Ślusarz Robert
Published: July 2023

The Barthel scale assesses the ability of the tested person to function independently. It plays an important role in the professional work of nurses. Therefore, the aim of the work is to characterize the Barthel scale and use it in the care of a neurological patient. This tool measures the degree of independence in activities of daily living. Thanks to this, it also helps to determine the level of assistance required with care and activities of daily living. This scale evaluates 10 basic daily activities. In Poland, the Barthel Index is one of the most frequently used assessment scales for measuring activity limitations in patients with various diseases, e.g. nervous system. Many researchers also use BI as one of the measurement tools to conduct scientific research. That is why it is so important to deepen knowledge about this tool. (JNNN 2022;11(4):180–184)
Delaying the GABA Shift Indirectly Affects Membrane Properties in the Developing Hippocampus

Published: July 2023

During the first two postnatal weeks, intraneuronal chloride concentrations in rodents gradually decrease, causing a shift from depolarizing to hyperpolarizing GABA responses. The postnatal GABA shift is delayed in rodent models for neurodevelopmental disorders and in human patients, but the impact of a delayed GABA shift on the developing brain remains obscure. Here we examine the direct and indirect consequences of a delayed postnatal GABA shift on network development in organotypic hippocampal cultures made from 6- to 7-d-old mice by treating the cultures for 1 week with VU0463271, a specific inhibitor of the chloride exporter KCC2. We verified that VU treatment delayed the GABA shift and kept GABA signaling depolarizing until DIV9. We found that the structural and functional development of excitatory and inhibitory synapses at DIV9 was not affected after VU treatment. In line with previous studies, we observed that GABA signaling was already inhibitory in control and VU-treated postnatal slices. Surprisingly, 14 d after the VU treatment had ended (DIV21), we observed an increased frequency of spontaneous inhibitory postsynaptic currents in CA1 pyramidal cells, while excitatory currents were not changed. Synapse numbers and release probability were unaffected. We found that dendrite-targeting interneurons in the stratum radiatum had an elevated resting membrane potential, while pyramidal cells were less excitable compared with control slices. Our results show that depolarizing GABA signaling does not promote synapse formation after P7, and suggest that postnatal intracellular chloride levels indirectly affect membrane properties in a cell-specific manner.

SIGNIFICANCE STATEMENTDuring brain development, the action of neurotransmitter GABA shifts from depolarizing to hyperpolarizing. This shift is a thought to play a critical role in synapse formation. A delayed shift is common in rodent models for neurodevelopmental disorders and in human patients, but its consequences for synaptic development remain obscure. Here, we delayed the GABA shift by 1 week in organotypic hippocampal cultures and carefully examined the consequences for circuit development. We find that delaying the shift has no direct effects on synaptic development, but instead leads to indirect, cell type-specific changes in membrane properties. Our data call for careful assessment of alterations in cellular excitability in neurodevelopmental disorders.
Students' learning experiences with synchronised emergency remote online education
Authors: Addam Billey , Omodan Bunmi Isiah
Published: July 2023

The global intervention by universities to minimise the devastating effect of the COVID-19 pandemic on education compelled many institutions to resort to emergency online curriculum facilitation, especially using virtual platforms. As a result, institutions adopted asynchronous, or synchronous, or both to facilitate knowledge with students. This study explored the reality of students' experiences with contemporaneous (synchronous) online teaching and learning model adopted by a university in South Africa. This study employed an interpretive qualitative methodological design. Data was gathered through an open-ended questionnaire administered to twenty students purposively sampled from a population of sixty-eight rurally resident final year students and focus group interviews with six of the twenty students. Data was analysed using constructs generated from connectivism theoretical framing which served as the compass used to navigate the study. The study revealed digital interaction space to be new to many students, especially those from the deep rural areas of South Africa. Furthermore, institutional readiness was limited, hence lack of support (awareness, resources, etc.) for students at the initial implementation stage of the programme. However, students and university academics were committed, coupled with self-discipline, and through social and academic engagements, benefited from the system. Flexibility, continuous academic interaction with peers, instantaneous authentic feedback and improved proficiency in using online tools were their constructive experiences. Nonetheless, they highlighted concerns of perceptions, bad network and poor connectivity, less cognitive engagement and unsuitable learning environments. The study recommends the introduction of asynchronous alongside the synchronous model of curriculum engagement to enhance the flexibility of learning opportunities.

Caring becomes an essential concept in fundamental nursing and is impactful in the quality of health services and nursing practice. However, factors in educational level among nursing students contribute to shaping and creating good caring behavior among nurses in clinical settings. The purpose of this study aimed to explore factors associated with caring among nursing students. A survey using a cross-sectional study was conducted in this study. It involved nursing students in a clinical phase amount of 256 respondents. The sampling technique was quota sampling and questionnaires were used to assess caring and organizational factors. The Chi-square test and binary logistic regression were employed to explore the determinant factors of caring behavior. Most of the percentage of nursing students caring behavior was 50% good category which was mostly aged 17-25 years (49.4%) and female (51.2%). Emotional (OR=3.49; 95% CI=1.45-8.44) and quantitative workload (OR=0.29; 95% CI=0.10-0.84) were significantly related to caring behavior among nursing students. The proportion of nursing students who have good and poor caring behavior was found equal. Moreover, significant results were also noted between emotional workload and caring behavior. Providing quality education is necessary to ensure nursing students can improve their ability to care for patients.

Isolated systolic hypertension (ISH) reflects atherosclerosis. Studies reported hypertension prevalence among diabetes mellitus (DM); however, limited studies provided community prevalence. The present study aimed to explore ISH prevalence among DM in Indonesia. This study obtained data from the 2018 Indonesia Basic Health Survey. The DM category was determined by fasting plasma glucose (PG) level ≥126 mg/dL or 2 hours postprandial and random PG level ≥200 mg/dL or previously diagnosed by a doctor. ISH is categorized if systolic blood pressure is≥140 mmHg and diastolic blood pressure is 90 mmHg. This study also explored the subject’s determinants, i.e., compliance, demography, and lipid profile. A Chi-square and Binary logistic regression were used to determine the association. The study included 3,911 DM individuals and disclosed the prevalence of ISH at 17.5%. ≥65 years old (OR=13.61 95%CI: 3.297-19.365) and 45-64 years old OR=4.59 95%CI: 3.297-6.383)), high HDL-cholesterol (OR=0.77; 95%CI: 0.626-0.936), and longer DM duration (OR=2.89; 95%CI: 2.405-3.474), all together were related to the ISH. Subjects with the oldest age category, i.e., ≥65 years old, had the highest OR. Older DM individuals with low HDL-C and longer DM duration were related to the ISH, suggesting lipid profile treatments, mainly the HDL-C, is a pivotal effort to delay ISH.

Hospital service quality should be developed based on customer needs and satisfaction. Long service time at Bhayangkara Kediri Hospital Outpatient Unit (267,62 ± 136,41 min) becomes a problem for management. The process is an asset for an organization, especially the core process should be well managed. Business process management has been viewed as an effective concept to improve processes continuously. It is an operational research combining document review, stakeholder interview, focused group discussion, quantitative and qualitative process analyze, prioritization, and root cause analysis to give process redesign recommendations. There are five core processes in the outpatient unit, and we focus our research on the dispensing process in pharmacy. Then we made a process model based on evidence and interview-based discovery. The cycle time efficiency of the prescription analysis process was the worst with a value of 0.31. With non-value activities reach to 40% of all activities with the waste are over processing, waiting, and transportation. The selected problem was the disposition of prescriptions to the dispensing unit as waste. Based on the root cause analysis, we suggest two recommendations. For the short-term redesign, we support the use of a basket to transport the prescription embedded in the operational procedures. And for the long-term redesign, we suggest the implementation of electronic prescribing. These redesigns are assumed to reduce waiting time by 2.5 – 16.2 % of service time.

This study aimed to assess the association between home environment and larval indices during the COVID-19 pandemic transition. A cross-sectional design was carried out in this study. The population was the houses in two villages of Gamping Sub-District, Sleman, Yogyakarta Province. The sample was calculated by considering the confidence interval value of 95%, the margin error of 5%, and the distribution response of 50%. Accordingly, the minimum sample size was 207 households. The chi-square test was used to analyze the data. The home environment was associated with the value of the container index (CI), indicated by a significant difference p-value of 0.008 with a prevalence ratio of 3.630, which means an unhealthy house will increase the value of the container index by 3.630 times greater. Sanitation of the home environment showed a significant relationship with the value of the container index (CI) with a p-value of 0.019 and a prevalence ratio of 2.625, which means that poor sanitation conditions will increase the value of the container index by 2.625 times. The health of the home environment is associated with the mosquito larvae index.

Hypertension, otherwise known as high blood pressure, is a condition that describes blood pressure significantly in the interval above 140/90 mmHG, which results in the death of 9.4 million people every year worldwide, with the incidence of the problem increasing over time. According to WHO, it is predicted that 1.28 billion or about 42% of people worldwide are diagnosed with hypertension, and the results of the 2018 Riskesdas suggest that the prevalence of hypertension in Indonesia increased to 34.1% from 25.8% in 2013. The type of research used is analytic observational with a cross-sectional study approach. The population in this study were all visitors recorded in the Internal Medicine Clinic register book at Latemmamala Hospital from January to December 2021, namely 707 people. The sampling technique used was simple random sampling with a total sample size of 148 people. This study finds that nutritional status (p=0.002), total cholesterol levels (p=0.000), abdominal circumference size (=0.000), and family history (p=0.000) had a relationship with the incidence of hypertension. As well as, type of work (p=0.078), marital status (p=0.916), stress level (p=0.079), smoking habits (p=0.261), and physical activity (p=0.376) have no relationship with the incidence of hypertension. This study shows a relationship between nutritional status, cholesterol levels, abdominal circumference size, and family history of hypertension. It is highly recommended for people with hypertension adopt a healthy lifestyle, such as maintaining a diet and regular physical activity to keep their blood pressure under control.

Measles is a highly contagious disease caused by the morbillivirus. According to WHO data, measles is one of the worldwide leading causes of death in children and infants. Indonesia is one of the ten countries with the most significant measles cases worldwide. Cases in Indonesia have increased due to a decrease in immunization coverage in Indonesia during the pandemic.  Besides low immunization coverage, other factors that influence the incidence of measles in Indonesia are nutritional status, mother’s knowledge, and occupancy density. This study aims to analyze the risk factors of immunization status, nutritional status, Mother’s knowledge, and occupancy density for measles in Indonesia.  This study used a meta-analysis method. The data sources used are Google Scholar, Pubmed, and Science Direct, from 2012-2021. The research articles found in this study are 148 articles. The report is then selected by screening to choose the year and research method and continued selection using inclusion criteria. Thus, the articles analyzed in this article are 23 research articles. The results showed that the variable immunization status, nutritional status, Mother knowledge, and occupancy density have risk factors for the incidence of measles in Indonesia. The result of measuring the pooled OR value sequentially from immunization status, nutritional status, mother’s knowledge, and occupancy density is e1.26=3.53; e0.72= 2.05; e1.36= 3.82;  e1.34= 3.89. The variable with the highest risk factor value for measles incidence in Indonesia is the occupancy density, followed by the Mother’s knowledge; immunization status; and nutritional status.
