Aim: This study was carried out to determine the prevalence of internet addiction in medical school students, and to examine the relationship between internet addiction and sleep quality, sleepiness and psychological resilience.

Method: The study was conducted with 213 participants studying at Bolu Abant Izzet Baysal University Faculty of Medicine. A sociodemographic questionnaire, Young Internet Addiction Test-Short Form, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale and Brief Psychological Resilience Scale were applied to all participants, and the results were statistically evaluated.

Results: The average age of the participants was found as 21.25±2.00. 65.3% (n=139) of the participants were women and 27.2% (n=58) were first-year students. The average score of Young's internet addiction was 27.15±7.35; the average Pittsburgh Sleep Quality Index score was 5.49±2.47. 60% of them were evaluated as having poor sleep quality. Average Epworth Sleepiness Scale scores were 6.62±4.22; average scores of the Psychological Resilience Scale were 19.35±5.04. There was a positive and significant relationship between Young Internet Addiction and Pittsburgh Sleep Quality. As internet addiction increased, sleep quality decreased. A negative significant relationship was found between Young's Internet Addiction and the Brief Psychological Resilience Scale. As internet addiction increased, psychological resilience decreased.

Conclusion: In our study, it was determined that as internet addiction increased, sleep quality and psychological resilience decreased, and daytime sleepiness increased. We can improve sleep quality by preventing internet addiction, and increase participation in daily activities and psychological resilience by reducing daytime sleepiness.

Authors: Chuah Joshua , Yan Pingkun , Wang Ge , Hahn Juergen
Published: April 2024

Background: Machine learning (ML) and artificial intelligence (AI)-based classifiers can be used to diagnose diseases from medical imaging data. However, few of the classifiers proposed in the literature translate to clinical use because of robustness concerns. Materials and methods: This study investigates how to improve the robustness of AI/ML imaging classifiers by simultaneously applying perturbations of common effects (Gaussian noise, contrast, blur, rotation, and tilt) to different amounts of training and test images. Furthermore, a comparison with classifiers trained with adversarial noise is also presented. This procedure is illustrated using two publicly available datasets, the PneumoniaMNIST dataset and the Breast Ultrasound Images dataset (BUSI dataset). Results: Classifiers trained with small amounts of perturbed training images showed similar performance on unperturbed test images compared to the classifier trained with no perturbations. Additionally, classifiers trained with perturbed data performed significantly better on test data both perturbed by a single perturbation (p-values: noise = 0.0186; contrast = 0.0420; rotation, tilt, and blur = 0.000977) and multiple perturbations (p-values: PneumoniaMNIST = 0.000977; BUSI = 0.00684) than the classifier trained with unperturbed data. Conclusions: Classifiers trained with perturbed data were found to be more robust to perturbed test data than the unperturbed classifier without exhibiting a performance decrease on unperturbed test images, indicating benefits to training with data that include some perturbed images and no significant downsides.
Application of Sustainable Wood-Plastic Composites in Energy-Efficient Construction
Authors: Shih Yeng-Fong , Chang Chun-Wei , Hsu Teng-Hsiang , Dai Wei-Yi
Published: April 2024

Wood–plastic composites (WPCs), abbreviated as WPCs, are typically composite materials made by mixing wood flour and thermoplastic resins, and then shaped through processes such as extrusion or compression. They have emerged as a viable and advanced alternative to traditional wood and plastic materials, offering an amalgamation of the best properties of both. This study utilized discarded milk bottles as the polymer matrix (mainly composed of high-density polyethylene, HDPE) and added wood flour, recycled protective clothing (Tyvek®), and diatomite recycled from brewery waste as reinforcement. Additionally, pre-treated aluminum hydroxide powder from waste artificial marble was added. The results indicated that the optimal processing temperature for the WPCs was 175 °C. The mechanical properties of the material increased with the addition of recycled protective clothing and pre-treated aluminum hydroxide powder. The increase in tensile strength can reach up to 28%. The thermal conductivity of the WPCs also significantly increased with the addition of pre-treated aluminum hydroxide powder. Furthermore, sunlight analysis showed that the surface temperature of the WPCs decreased by approximately 8.5 °C, which corresponds to a reduction of 13% after adding pre-treated aluminum hydroxide powder. Therefore, they can be applied to outdoor cool WPCs to reduce the risk of foot burns or used as roof heat-insulating layers to reduce indoor air conditioning usage, achieving energy-saving and carbon reduction. This study demonstrates that high-performance and high-value green plastics made from various recycled materials can contribute to the goals of a circular economy and sustainable carbon reduction.

Authors: Zhang Nan , Yang Guolai , Su Bo , Song Weilong
Published: April 2024

Due to the inherent challenges in meeting the comprehensive training requirements of combat scenarios within a digital environment, this paper proposes innovative solutions. Firstly, a parametric scene training method is introduced, aiming to enhance the adaptability of the training process. Secondly, the utilization of the digital environment as a test environment is suggested, which can significantly improve the efficiency of iterative virtual-to-real conversion. Additionally, employing digital simulation as a pre-test environment for the physical setting can effectively reduce deployment costs and enhance the safety of virtual reality migration experiments. The proposed approach involves constructing a training model based on the parameterized environment and implementing a feedback loop utilizing the digital environment agent model. This framework enables continuous verification of the environment’s parameters, ensuring the accuracy of decision-making strategies and evaluating the transferability of the decision-making model.
The Genealogy of Play
Authors: Jarvis Pam
Published: April 2024

In 1924, exactly a century ago, the world-famous children’s author Alan Milne wrote this much-loved rhyme about the play activities of his young son: Where am I going? I don’t quite know. Down to the stream where the king-cups grow-Up on the hill where the pine-trees blow-Anywhere, anywhere. I don’t know…Where am I going? The high rooks call: “It’s awful fun to be born at all”. Where am I going? The ring-doves coo: “We do have beautiful things to do”. But in 2024, in much of the Western world, allowing a young child to wander in this manner would be seen by many as dangerous, reckless and negligent. For example, in 2019, Renee Umstattd Meyer and her colleagues found that a large proportion of children in the post-industrial world did not take the recommended amount of exercise in the outdoor environment, and even where spaces were specifically made available to them, parents feared that they would be infiltrated by crime and violence. This article considers the emergent effects of significant cultural change in children’s independent and collaborative free play opportunities. It draws on an ethological and biocultural perspective to argue why independent, active free play, particularly involving peer collaboration, is so important to human development.

Published: April 2024

Background: Minimally invasive aortic valve replacement (AVR) via upper ministernotomy (MiniAVR) is a standard alternative to full sternotomy access. Minimally invasive cardiac surgery has been proven to provide a number of benefits to patients. The aim of this study was to compare the short- and long-term outcomes after MiniAVR versus conventional AVR via full sternotomy (FS) using a biological prosthesis in an elderly higher-risk population. Methods: Between January 2006 and July 2009, 918 consecutive patients received AVR ± additional procedures with different prostheses at our center. Amongst them, 441 received isolated AVR using a biological prosthesis (median age of 74.5; range: 52–93 years; 50% females) and formed the study population (EuroSCORE II: 3.62 ± 5.5, range: 0.7–42). In total, 137 (31.1%) of the operations were carried out through FS, and 304 (68.9%) were carried out via MiniAVR. Follow-up was complete in 96% of the cases (median of 7.6 years, 6610 patient-years). Propensity score matching (PSM) resulted in two groups of 68 patients with very similar baseline profiles. The primary endpoints were long-term survival, freedom from reoperation, and endocarditis, and the secondary endpoints were early major adverse cardiac and cerebrovascular events (MACCEs). Results: FS led to shorter cardio-pulmonary bypass and aortic cross-clamp durations: 90 (47–194) vs. 100 (46–246) min (p = 0.039) and 57 (33–156) vs. 69 (32–118) min (p = 0.006), respectively. Perioperative stroke occurred in three patients (4.4%; FS) vs. one patient (1.5%; MiniAVR) (p = 0.506). The 30-day mortality was similar in both groups (2.9%, p = 1.000). Survival at 1, 5, and 10 years was 94.1 ± 3% (FS and MiniAVR), 80.3 ± 5% vs. 75.7 ± 5%, and 45.3 ± 6% vs. 43.8 ± 6%, respectively (p = 0.767). There were two (2.9%) reoperations in each group and two thrombo-embolic events (2.9%) vs. one (1.5%) thrombo-embolic event in the MiniAVR and FS groups, respectively (p = 0.596). Conclusions: In comparison to FS, MiniAVR provided similar short- and long-term outcomes in a higher-risk elderly population receiving biological prostheses. In particular, long-term survival, freedom from reoperation, and the incidence of endocarditis were comparable. These results clearly advocate for the routine use of MiniAVR as a standard procedure for AVR, even in a high-risk population.
A Blockchain-Based Decentralized Public Key Infrastructure Using the Web of Trust
Authors: Halder Ratna , Das Roy Dipanjan , Shin Dongwan
Published: April 2024

Internet applications rely on Secure Socket Layer (SSL)/Transport Security Layer (TSL) certifications to establish secure communication. However, the centralized nature of certificate authorities (CAs) poses a risk, as malicious third parties could exploit the CA to issue fake certificates to malicious web servers, potentially compromising the privacy and integrity of user data. In this paper, we demonstrate how the utilization of decentralized certificate verification with blockchain technology can effectively address and mitigate such attacks. We present a decentralized public key infrastructure (PKI) based on a distributed trust model, e.g., Web of Trust (WoT) and blockchain technologies, to overcome vulnerabilities like single points of failure and to prevent tampering with existing certificates. In addition, our infrastructure establishes a trusted key-ring network that decouples the authentication process from CAs in order to enhance secure certificate issuance and accelerate the revocation process. Furthermore, as a proof of concept, we present the implementation of our proposed system in the Ethereum blockchain, confirming that the proposed framework meets the five identified requirements. Our experimental results demonstrate the effectiveness of our proposed system in practice, albeit with additional overhead compared to conventional PKIs.
The Absence of Islands in Akan: The Role of Resumption
Authors: Korsah Sampson , Murphy Andrew
Published: April 2024

The precise nature of Ā-dependencies that terminate in a pronoun has been a long-standing subject of cross-linguistic research. Traditionally, it has been assumed that there are two derivational strategies to form resumptive Ā-dependencies: movement and base generation. Island configurations have played a crucial role in determining which derivational strategy is employed in a given language, as islands effects are expected to arise from dependencies created by movement but not by base generation. The body of cross-linguistic research on resumption has shown that the situation is more complicated once other diagnostics are taken into account, as languages can have mixed resumption profiles. In this paper, we discuss resumption in Ā-dependencies in Akan, a Kwa language spoken in Ghana, and illustrate that, despite their general insensitivity to islands, resumptive dependencies also show many classic hallmarks of movement. We situate these findings in the broader context of a general understanding of resumption cross-linguistically and discuss how the conflicting diagnostics might be reconciled with a movement-based analysis.

Published: April 2024

Psychrophilic anaerobic digestion emerges as an appealing integrated solution for the management of agricultural waste, particularly for farmers in regions where the average temperature does not exceed 26 °C, as seen in coffee cultivation. Therefore, this study seeks to assess the biomethane potential of thermochemical-treated coffee husk through psychrophilic anaerobic digestion (C3-20 °C-w/pretreatment). To examine its viability, outcomes were compared with reactors operating at both mesophilic (C1-35 °C) and psychrophilic (C2-20 °C) conditions, albeit without the use of pretreated coffee husk. The C3-20 °C-w/pretreatment test demonstrated a 36.89% increase (150.47 NmL CH4/g VS; 161.04 NmL CH4/g COD), while the C1-35 °C test exhibited a 24.03% increase (124.99 NmL CH4/g VS; 133.77 NmL CH4/g COD), both in comparison to the C2-20 °C test (94.96 NmL CH4/g VS; 101.63 NmL CH4/g COD). Notably, the C3-20 °C-w/pretreatment trial yielded superior outcomes, accompanied by an associated energy output of 3199.25 GWh/year, sufficient to meet the annual energy demands of 494 residences. This marks an increase of 83 and 182 million residences compared to the mesophilic and psychrophilic AD of CH without pretreatment, respectively.

Published: April 2024

Quinoa, known as the “golden grain” for its high nutritional value, has polysaccharides as one of its sources of important nutrients. However, the biological functions of quinoa polysaccharides remain understudied. In this study, two crude polysaccharide extracts of quinoa (Q-40 and Q-60) were obtained through sequential precipitation with 40% and 60% ethanol, with purities of 58.29% (HPLC) and 62.15% (HPLC) and a protein content of 8.27% and 9.60%, respectively. Monosaccharide analysis revealed that Q-40 contained glucose (Glc), galacturonic acid (GalA), and arabinose (Ara) in a molar ratio of 0.967:0.027:0.006. Q-60 was composed of xylose (xyl), arabinose (Ara), galactose, and galacturonic acid (GalA) with a molar ratio of 0.889:0.036:0.034:0.020. The average molecular weight of Q-40 ranged from 47,484 to 626,488 Da, while Q-60 showed a range of 10,025 to 47,990 Da. Rheological experiments showed that Q-40 exhibited higher viscosity, while Q-60 demonstrated more elastic properties. Remarkably, Q-60 showed potent antioxidant abilities, with scavenging rates of 98.49% for DPPH and 57.5% for ABTS. Antibacterial experiments using the microdilution method revealed that Q-40 inhibited the growth of methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli (E. coli), while Q-60 specifically inhibited MRSA. At lower concentrations, both polysaccharides inhibited MDA (MD Anderson Cancer Center) cell proliferation, but at higher concentrations, they promoted proliferation. Similar proliferation-promoting effects were observed in HepG2 cells. The research provides important information in the application of quinoa in the food and functional food industries.

Published: April 2024

In addition to general anesthesia and mechanical ventilation, robotic-assisted laparoscopic radical prostatectomy (RALP) necessitates maintaining a capnoperitoneum and placing the patient in a pronounced downward tilt (Trendelenburg position). While the effects of the resulting fluid shift on the cardiovascular system seem to be modest and well tolerated, the effects on the brain and the blood–brain barrier have not been thoroughly investigated. Previous studies indicated that select patients showed an increase in the optic nerve sheath diameter (ONSD), detected by ultrasound during RALP, which suggests an elevation in intracranial pressure. We hypothesize that the intraoperative fluid shift results in endothelial dysfunction and reduced cerebral clearance, potentially leading to transient neuronal damage. This prospective, monocentric, non-randomized, controlled clinical trial will compare RALP to conventional open radical prostatectomy (control group) in a total of 50 subjects. The primary endpoint will be the perioperative concentration of neurofilament light chain (NfL) in blood using single-molecule array (SiMoA) as a measure for neuronal damage. As secondary endpoints, various other markers for endothelial function, inflammation, and neuronal damage as well as the ONSD will be assessed. Perioperative stress will be evaluated by questionnaires and stress hormone levels in saliva samples. Furthermore, the subjects will participate in functional tests to evaluate neurocognitive function. Each subject will be followed up until discharge. Conclusion: This trial aims to expand current knowledge as well as to develop strategies for improved monitoring and higher safety of patients undergoing RALP. The trial was registered with the German Clinical Trials Register DRKS00031041 on 11 January 2023.

Published: April 2024

Pediatric onset multiple sclerosis (POMS), characterized by the onset of multiple sclerosis before the age of 18, is gaining increased recognition. Approximately 5 percent of MS cases manifest before the age of 18, with less than 1 percent occurring before the age of 10. Despite its rarity, pediatric MS exhibits distinct characteristics, with an association between younger age at onset and a comparatively slower disease progression. Despite this slower progression, individuals with POMS historically reach disability milestones at earlier ages than those with adult-onset multiple sclerosis. While various immunomodulatory agents demonstrate significant benefits in MS treatment, such as reduced relapse rates and slower accumulation of brain lesions on magnetic resonance imaging (MRI), the majority of disease-modifying therapies (DMTs) commonly used in adult MS lack evaluation through pediatric clinical trials. Current evidence is predominantly derived from observational studies. This comprehensive review aims to consolidate existing knowledge on the mechanisms of action, efficacy, safety profiles, and recommended dosages of available DMTs specifically in the context of pediatric MS. Furthermore, this review outlines recent advancements and explores potential medications still in developmental stages, providing a thorough overview of the current landscape and future prospects for treating POMS.

Enhancing Traffic Sustainability: An Analysis of Isolation Intersection Effectiveness through Fixed Time and Logic Control Design Using VisVAP Algorithm
Authors: Duraku Ramadan , Boshnjaku Diellza
Published: April 2024

This paper addresses the limitations of the fixed-time approach in traffic signal control, which can lead to bottlenecks and inefficiencies. Proposing an alternative algorithm based on design logic control, the study integrates data from inductive detectors and non-linear traffic flow rates to optimize signaling plans. Analytical models are developed for both fixed and semi-actuated traffic signal control approaches, with PTV Vissim software (version 8, 64 bit) used for simulation. The design logic control dynamically adjusts signaling plans, determining the duration of the green interval for the secondary road based on arrival traffic flow. In the absence of traffic, it eliminates the green interval, advancing to the next phase, thereby reducing cycle time. This dynamic adjustment follows a conditional “if-then” statement, optimizing traffic signal operation. The design logic control algorithm was tested in a real isolation intersection with four scenarios, using non-linear traffic flow rate data for one peak hour. Results demonstrated that the proposed design logic control, based on the Semi-Actuated Traffic Signal Control (SATSC) approach, outperformed the commonly used Fixed-Time Signal Control (FTSC) with overall reduction of queue lengths by 39.6% and reduction of vehicle delays by 51.3%. The findings suggest its viability as a solution for many cities, contributing to a more sustainable traffic system.
Isolation of Cardanol Fractions from Cashew Nutshell Liquid (CNSL): A Sustainable Approach
Authors: Bhatia Bhavika , Amarnath Nagarjuna , Rastogi Sumit K. , Lochab Bimlesh
Published: April 2024

Exploring sustainable approaches to replace petroleum-based chemicals is an ongoing challenge in reducing the carbon footprint. Due to the complexity and percentage variation in nature-generated molecules, which further varies based on geographical origin and the purification protocol adopted, a better isolation strategy for individual components is required. Agrowaste from the cashew industry generates phenolic lipid (cardanol)-rich cashew nutshell liquid (CNSL) and has recently shown extensive commercial utility. Cardanol naturally exists as a mixture of three structurally different components with C15-alkylene chains: monoene, diene, and triene. The separation of these three fractions has been a bottleneck and is crucial for certain structural designs and reproducibility. Herein, we describe the gram-scale purification of cardanol into each component using flash column chromatography within the sustainability framework. The solvent used for elution is recovered and reused after each stage (up to 82%), making it a cost-effective and sustainable purification strategy. This simple purification technique replaces the alternative high-temperature vacuum distillation, which requires substantial energy consumption and poses vacuum fluctuation and maintenance challenges. Three components (monoene 42%, diene 22%, and triene 36%) were isolated with good purity and were fully characterized by 1H and 13C NMR, GC-MS, HPLC, and FTIR spectroscopy. The present work demonstrates that greener and simpler strategies pave the way for the isolation of constituents from nature-sourced biochemicals and unleash the potential of CNSL-derived fractions for high-end applications.
An Evaluation of Correlations for Predicting the Heat Transfer Coefficient during the Condensation of Saturated and Superheated Vapors Inside Channels
Authors: Shah Mirza M.
Published: April 2024

Condensation heat transfer is involved in many industrial applications. Therefore, it is important to know the relative accuracy of the available methods for predicting heat transfer. Condensation can occur with saturated as well as superheated vapors. Predictive methods for both conditions were evaluated using a wide range of data. Twelve well-known correlations for the condensation of saturated vapor, including the most recent ones, were compared with data for 51 pure fluids and mixtures from 132 sources in horizontal and vertical channels of many shapes. Channel hydraulic diameters were 0.08–49 mm, the mass flux was 1.1–1400 kg/m2s, and the reduced pressure range was 0.0006–0.949. The fluids included water, CO2, ammonia, hydrocarbons, halocarbon refrigerants, various chemicals, and heat transfer fluids. The best predictive technique was identified. The three most commonly used models for heat transfer during the condensation of superheated vapors were studied. They were first compared with test data using measured saturated condensation and forced convection heat transfer coefficients to select the best model. The selected model was then compared with test data using various correlations for heat transfer coefficients needed in the model. The best correlations to use in the model were identified. The results of this research are presented, as are recommendations for use in design.
A New Strategy for Railway Bogie Frame Designing Combining Structural–Topological Optimization and Sensitivity Analysis
Authors: Cascino Alessio , Meli Enrico , Rindi Andrea
Published: April 2024

Rolling stock manufacturers are finding innovative structural solutions to improve the quality and reliability of railway vehicles components. Structural optimization processes represent an effective strategy for reducing manufacturing costs, resulting in geometries easier to design and produce. In this framework, the present paper proposes a new methodology to design a railway metro bogie frame, combining structural–topological optimization methods and sensitivity analysis. In addition, manufacturing constraints were included to make the component design suitable for production through sand-casting. A robust sensitivity analysis has highlighted the most critical load conditions acting on the bogie frame. Its effectiveness was verified by carrying out two different structural optimizations based on different loadings. Two equivalent designs were obtained. Computational times were positively reduced by about 57%. The maximum value of stress was reduced about 23%. This new methodology has shown encouraging results to streamline the design process of this complex mechanical system, allowing researchers to also include manufacturing requirements.
True Diaphragmatic Hernia (Morgagni Hernia) Incidentally Diagnosed with Positive Contrast Peritoneography in a Cat: A Rare Case Report and a Review
Authors: Deschamps Jack-Yves , Corbarieu Théo , Abboud Nour , Roux Françoise A.
Published: April 2024

An 18-month-old neutered male domestic shorthair cat was presented for an emergency consultation after falling from the second floor. The cat sustained minor traumatic injuries but did not exhibit dyspnea. Routine radiographic examination raised suspicion of a diaphragmatic hernia, but the circumscribed nature of the soft tissues visible in the thorax was atypical for a classic traumatic diaphragmatic hernia. A positive contrast peritoneography highlighted the likely presence of a hernial sac, which strongly suggested a “true diaphragmatic hernia”, also known as “pleuroperitoneal hernia”. This diagnosis was confirmed during laparotomy, which allowed for the visualization of a 3 cm radial diaphragmatic defect in the right ventral quadrant of the pars sternalis. The diaphragm’s edges were rounded. A portion of the falciform ligament and a part of the omentum were protruding through the defect and were contained within a hernial sac. Herniorrhaphy was performed. The cat recovered without complications. Given its presentation and location, ventrally and to the right, this anomaly is analogous to what is described in humans as “Morgagni hernia”. Six other cases of Morgagni hernias have probably been reported in cats but were not identified as such. This case underscores the utility of peritoneography, a straightforward technique useful for diagnosing diaphragmatic hernias, which enables differentiation between acquired traumatic forms and congenital forms, particularly peritoneopericardial hernias and pleuroperitoneal hernias. True diaphragmatic hernias are almost always serendipitous discoveries.
Optimal and Quasi-Optimal Automatic Tuning of Vibration Neutralizers
Authors: Rustighi Emiliano
Published: April 2024

Vibration neutralizers are single-degree-of-freedom devices affixed to vibrating structures in order to reduce the response at a specific troublesome harmonic excitation frequency. As this frequency may vary over time, it becomes imperative to track and adjust the neutralizer to maintain the optimal performance. Recent years have witnessed the emergence of adaptive tunable vibration neutralizers, offering real-time adjustment capabilities through external actions. Thanks to real-time control algorithms, these devices enable the automatic mitigation of vibration levels in mechanical structures. A particularly successful algorithm for the automatic tuning of these devices leverages the phase angle between the base acceleration and the neutralizer’s mass. This study critically examines the justification for employing such an algorithm and scrutinizes its optimal applicability limits, particularly in the context of viscous and structurally damped systems. The findings reveal that this algorithm accurately approximates optimum tuning for systems with low damping. Moreover, from an engineering perspective, the algorithm remains acceptable even for heavily damped structures. Through a focused and comprehensive analysis, this paper provides valuable insights into the efficacy and limitations of the phase-angle-based tuning algorithm, contributing to the advancement of adaptive vibration control strategies in smart structures.
Signature functional control method of the digital automatic devices with programmable logic
Authors: Tupkalo Viltalii , Cherepkov Serhii
Published: April 2024

Today, programmable digital automatic devices have become an integral part of various control, measurement, and control digital devices and systems. Therefore, in the conditions of the cyberattacks spread, the programmable digital automatic devices software becomes one of the most cyber-vulnerable components of modern digital systems for ensuring the operation of critical infrastructure objects. As a result, the problem of finding effective methods for ensuring the efficiency and reliability of monitoring the program's progress at each cycle of addressing the tuple of programmable digital automatic device commands in the real-time scale of their target functioning is becoming more relevant. In the article, based on a critical analysis of the well-known methods of controlling the progress of programs, a method of ensuring the operational controllability of the programmable digital automatic devices is proposed based on the principle of predicting the control signature of the command at each subsequent addressing cycle relative to its previous cycle. At the same time, the possibility of such control for a set of basic (typical) simple structures of addressing algorithms (linear following, branching, and cycle) has been proven as the basis for solving the compositional problem of ensuring the signature controllability of the progress of programs (microprograms) by the method of predicting control signatures for non-elementary addressing algorithms commands. In the context of the practical implementation of the proposed method of signature control, a formulas system of control signature equations (rules of signature functional control) is presented. This makes it possible to implement a new principle of functional control of the digital automatic device — checking automatic device functioning in real-time by introducing unified hardware control redundancy from functionally complete elementary structures of the combinational type. It was determined that the further topic of the article is the development of automated software for the structural synthesis of hardware redundancy (nodes of signature functional control) using the method of predicting signatures for digital automatic devices with «flexible» logic for various purposes. At the same time, the mathematical apparatus of the author's signature Boolean-polynomial algebra is proposed as the basis of structural synthesis.

Tujuan penelitian untuk mengetahui perbedaan waktu kontak sinar UV-C terhadap penurunan bakteri coliform pada air minum. Penyediaan air minum yang ada di PT. X bersumber dari sumur artesis. Populasi sampel adalah ruang produksi PT. X. Teknik pengambilan sampel berupa grab sampling dengan besar sampel 2,4 L. Alat pengumpul data menggunakan Most Probable Number (MPN) untuk menghitung coliform.  Teknik pengumpulan data dengan pemeriksaan bakteri di laboratorium. Pada hasil pengujian didapatkan hasil jumlah bakteri yaitu 2 x 103 CFU/100 ml sampel. Menurut Permenkes RI No, 492 Tahun 2010 tentang Persyaratan Kualitas Air Minum, persyaratan air minum untuk angka bakteri coliform yaitu 0 CFU/100 ml sampel. Jenis penelitian ini eksperimen dengan desain post-test with control. Hasil pemeriksaan bakteri coliform pada air minum sebelum melewati paparan desinfeksi sinar ultraviolet (UV-C) diperoleh hasil lebih dari 330 CFU/100 ml, setelah melewati paparan desinfeksi sinar ultraviolet (UV-C) diperoleh hasil berkisar antara 0 – 12 CFU/100 ml. Analisis data menggunakan Kruskal Wallis didapatkan bahwa P value (Significant) yaitu sebesar <0,001 di mana angka tersebut < 0,05 maka Ho ditolak dan Ha diterima sehingga dapat disimpulkan terdapat perbedaan yang signifikan antara variasi waktu kontak paparan desinfeksi sinar ultraviolet terhadap penurunan bakteri coliform pada air minum.

Tujuan dari pembuatan tugas akhir adalah mengimplementasikan asuhan kebidanan komprehensif yang berpusat pada kebutuhan klien untuk meningkatkan kualitas pelayanan kesehatan Ibu dan Anak. Tugas akhir berupa studi kasus dengan memberikan asuhan kebidanan kepada Ny.Y sejak usia kehamilan 38-39 minggu yang dilaksanakan di wilayah kerja Puskesmas Cipeundeuy Kabupaten Subang pada bulan April-Juni tahun 2021. Metode pengumpulan data menggunakan data primer dan data sekunder.

Selama asuhan kehamilan didapatkan masalah ketidakteraturan konsumsi suplemen zat besi dan mineral lainnya serta ketidaksesuaian kenaikan berat badan ibu pada saat hamil berdasarkan kategori IMT. Selama asuhan persalinan, nifas dan bayi baru lahir tidak ditemukan masalah dan komplikasi. Asuhan kehamilan, persalinan, nifas dan bayi baru lahir sudah dilaksanakan berdasarkan manajemen kebidanan dan standar asuhan kebidanan, permasalahan sudah teratasi. Terdapat kesenjangan antara teori dengan praktik yaitu kenaikan berat badan ibu kurang dari standar WHO, penjahitan tanpa anestesi, pemberian suplemen vitamin A dan antibotik pada ibu nifas serta memulangkan ibu dan bayi dibawah 24 jam setelah persalinan. Diharapkan mahasiswa lebih meningkatkan kompetensinya dalam memberikan asuhan komprehensif,deteksi dini dan konseling serta dapat memberikan asuhan yang komprehensif pada setiap pasien yang diasuhnya.
