On The Design of a Novel Smart Medicine Box Towards Detecting the Medicine Expiry Date and Facilitating Medication Planning for Visually Challenged

Population growth has led to the increase of different types of medication, burden on nurses and pharmacy clerks. Studies have shown that on an average a person takes about five different types of medication for any illness. This medication has led to several other medication errors as the patient is taking wrong medicine at the wrong time in a day. This is highly prevalent in people who are older in age and for the people, who are visual impaired or challenged. These people face difficulty in checking the expiry date of the medication because of smaller text size and fonts. It is well known that consumption of an expired product is fatal. To prevent this medication error, forgetting medicine intake and consumption of expired medication; the Smart Medicine Box idea is used. It is a boxlike structure with certain compartments. The compartment has LCD screen that displays the name of the medicine stored and the date of expiration for that medicine. In addition, the box contains speaker to announce the name of the medicine and date of expiration. To assist the visually impaired to take the correct medication vibration mechanism has been set up where the compartment containing the medicine to be taken at that time vibrates indicating to the user. Image processing technique is used to process and analyse the bar code of the medication for the expiration date and the name of the medication. Ultrasonic Sensors are used to detect the pending number of pills within the compartment; a microcontroller is used to control the process. In this research effort, after a critical overview of the state-of-the-art developments in this important field we outline in detail the proposed architecture for such an efficient smart medicine box, defining its components and its preliminary UML related diagrams.

Proposed Improvements to Production Facility Layout Using ARC and ARD at Home Industry Aurora Official

Home Industry Aurora Official, which is engaged in the manufacture of pillows and baby mattresses, faces problems related to inefficient facility layouts in the workflow. Suboptimal layouts result in excessive waste of distance, which affects production time and reduces operational efficiency. This study aims to design a more efficient facility layout by minimizing the distance between production processes. The methods used in this study are the ARC (Activity Relationship Chart) and ARD (Activity Relationship Diagram) methods, which can help design layouts based on the relationships between production activities and determine the relationships between activities based on their priority level of proximity. Based on the analysis results, the initial layout produces a total distance of 940 meters, while the two alternative proposed layouts produce distances of 310 meters and 405 meters respectively. Of the two proposed layouts, proposed layout 1 was chosen as the proposed layout for the company with a total distance of 310 meters, with a decrease of 67% from 100% of the total distance of the initial layout. The results of this study indicate that the application of proposed layout 1 can improve workflow efficiency and reduce waste time in the production process.

A Stocking Diagram for Even-aged Mixed Pine-Fir Stands of Kastamonu Region

Forest stand density diagrams help forest managers and practitioners more effectively manage stand density and tree occupancy to meet specific silvicultural goals. Therefore, creating such auxiliary silvicultural tools for different stands is essential. To our knowledge, no relative density graphs or diagrams have been developed for mixed stands in Türkiye. This study aimed to develop a stocking diagram for mixed Scots pine (Pinus sylvestris L.)-Kazdağı fir (Abies nordmanniana subsp. equi-trojani) stands. In the study, statistical relations between stocking percent and diameter increment in selected sample plots were also determined, and these statistical relations were compared with the "stand basal area-diameter increment relations" in the same sample plots. Stand stocking percent was found to be more descriptive than absolute density measurement units (i.e., basal area) in defining stand density in mixed Scots pine-Kazdağı fir stands. The resulting stock diagram may allow more effective use of stand growing space to achieve various silvicultural goals, including regeneration, thinning, and wildlife protection in mixed Scots pine- Kazdağı fir stands. Depicting various density measures including basal area, trees per ha, and stand stocking percent, the findings of this study would facilitate the tree density management in mixed Scots pine- Kazdağı fir stands.

Purpose/Significance Public health data is an important part of China's public data. It can help improve China's public data open system, realize the value that public health data should have, and achieve the goal of “building a community of shared future for human health” as soon as possible. Method/Process Using the topic mining model, the bibliographic information related to “public health data openness” in the CNKI and WOS is processed to find the influencing factors that affect the realization of public health data openness. Secondly, the mutual influence relationship between these factors is found, and using system dynamics, a causal relationship diagram and a system flow diagram are constructed to simulate and analyze the value realization model of China's public health data openness, and then the value realization path of China's public health data openness is summarized. Result The causal relationship diagram mainly includes four types of circuits, and 43 equation designed models have been determined through multiple simulation simulations. At the 22nd month, the value of “public health data” began to gradually emerge. At the same time, the slope of the line between “data security” and “timely response to data concerns” is also rapidly increasing. In the fourth month, the value of “public health data” remained relatively low and stable. Conclusion The realization path of China's public health data openness can be carried out from three aspects, namely, the “safety standards” on the supply side, the “quality and quantity of citizens” on the demand side, and the improvement of the relevant supervision mechanisms that connect the supply and demand sides, so as to effectively tap the potential value of China's public health data.

An Integrated DEMATEL with Bipolar neutrsophic Dombi-based Heronian Mean Operator and Its Applications in Decision-making Problem

The Decision-Making Trial and Evaluation Laboratory (DEMATEL) approach is commonly used in examining and illustrating the relationship between different factors in a complex system. This paper proposes a novel approach that integrates the Bipolar neutrosophic Dombi-based IGWHM operator into the DEMATEL method, in which the criteria are analyzed by means of the cause-and-effect relationship diagram. The current studies on the classical DEMATEL approach have some limitations on the aggregation process, particularly in capturing the interrelationship of individual arguments by assessing their impact on each other within a complex system. To enhance the aggregation of complex information in the decision-making framework, the Bipolar neutrosophic Dombi-based Improved Generalized Weighted Heronian mean (IGWHM) operators are employed. The applicability and effectiveness of the proposed approach are demonstrated when solving a selection of transport service providers. The ability of the method to highlight the intricate interdependencies and ranking criteria based on their importance. The sensitivity of the developed approach is observed with variations in the involved parameter. Moreover, a comparative analysis is made with other methods to demonstrate its validity.

Regional climatic changes and their impact on the level of avalanche hazard in East Kazakhstan.

The article examines the territory of East Kazakhstan, where a sharply continental climate prevails with hot summers, cold and snowy winters. The mountainous regions of East Kazakhstan are represented by the Kalba, Altai and Saur-Tarbagatay ranges, they are surrounded by rolling plains. The highest points are at 3000-4500m. On average, the heights are in the range of 900-1400m. Despite the low heights in the mountainous area, the problem of avalanche safety is acute in the region. At the same time, the situation is complicated by not always predictable weather events, the frequency of which is increasing every year. These include heavy precipitation, sometimes combined with a sharp warming in winter, and the changing wind regime of the territory. To identify regional climate changes and its connection with the avalanche-prone situation in the region, the study analyzed meteorological data from weather stations located directly near avalanche prone locations over the past 23 years since 2001, as well as data from observations of avalanche-prone areas since 2005 and information on registered spontaneous avalanches from 2013 to the present. This study is the first in the East Kazakhstan region, which presents the results of a comprehensive analysis of data on 497 avalanche-prone sites, of which 325 sites pose a threat to life and infrastructure. 10 most dangerous sites have been selected for detailed study. The analysis of climate data was carried out based on information from 7 weather stations. The article discusses the main climatic changes in the region, including an increase in air temperature, an increase in precipitation and a change in wind conditions. Data from weather stations and snow measuring routes covering the period since 2005 have been used to develop probabilistic avalanche forecasts. The use of statistical methods and the analysis of the relationships between meteorological parameters (temperature, precipitation, wind speed) made it possible to build models predicting avalanche-prone situations. Data on spontaneous avalanches were analyzed for five sites (Bogatyrevskaya site, Prokhodnaya, Sogornoye-Barlyk, Tainty and Pikhtovka). Based on these data, equations of dependence of temperature, wind and precipitation have been developed, which improves the accuracy of forecasting avalanche risks. An analysis of the data in the Statistica program showed a significant relationship between sudden warming, increased wind speed and precipitation, which precedes avalanches. Regression equations and the approximation confidence coefficient for the average values of the studied parameters are obtained. The results of the study make it possible not only to establish patterns, but also to propose effective methods for monitoring and forecasting avalanche hazard in the region. According to the data analysis, regional features of climate change in East Kazakhstan were identified, and a comparison was made with previously known works on Kazakhstan. The interrelation of climatic characteristics with avalanche hazard in the region is shown. The results obtained in the study will help us to better understand the regional manifestations of climate change. An important task for further forecasting of avalanche activity is the correct design of the avalanche collection database. The authors identified information objects (entities). An ontological database model (Entity Relationship Diagram) is constructed. Based on it, a database has been created for a system for monitoring and forecasting avalanche activity in the East Kazakhstan region.

Comprehensive Bibliometric Analysis on High Hydrostatic Pressure as New Sustainable Technology for Food Processing: Key Concepts and Research Trends

The industrial application of high hydrostatic pressure (HHP) can be traced back to the late 19th century in the fields of mechanical and chemical engineering. Its growth as a food preservation technique has developed and massified in certain countries in the last 30 years. However, there is no global overview of the research conducted on this topic. The aim of this study was to recognize global trends in the scientific population on the subject of HHP over time at the main levels of analysis: sources, authors, and publications. This article provides a summary of research related to the use of HHP through a bibliometric analysis using information obtained from the Web of Science (WoS) database between the years 1975–2023, using the terms “pascalization”,“high-pressure processing”, and “high hydrostatic pressure” as input keywords. The results are shown in tables, graphs, and relationship diagrams. The countries most influential and productive in high hydrostatic pressure are the People’s R China, the USA, and Spain, with 1578, 1340, and 1003 articles, respectively. Conversely, the authors with the highest metrics are Saraiva, J. (Universidade Aveiro-Portugal), Hendrickx, M. (Katholieke Universiteit Leuven-Belgium), and Wang, T. (China Agricultural University-China). The most productive journals are Innovative Food Science & Emerging Technologies, Food Chemistry, and LWT-Food Science and Technology, all belonging to Elsevier, with 457, 281, and 264 documents, respectively.

An Analysis of the Spatial Characteristics of Jin Ancestral Temple Based on Space Syntax

As a model of ancient Chinese architecture, Jin Ancestral Temple’s spatial layout and functional hierarchy reflect its profound cultural connotations and historical evolution. This paper systematically studies Jin Ancestral Temple from the perspectives of spatial relationships, visibility, and accessibility based on space syntax and visual graphics analysis methods. Through the construction and analysis of spatial relationship diagrams and topological diagrams, this study quantitatively identifies key differences in spatial depth and integration along the central axis of Jin Ancestral Temple. The sacrificial buildings, such as Uonuma Flying Beam and the Sacrificial Temple, exhibit high spatial depth and low integration, reflecting their secluded nature, which enhances the solemnity and focus of ritual activities. In contrast, landscape buildings like Jinren Terrace, with their low spatial depth and high integration, function as open spaces that facilitate movement and act as pivotal points in the visitor circulation network. Visual Graph Analysis (VGA) shows that the central axis area has the unique characteristics of a “visual center” and a “transportation hub”. The plaza on the north side of the reflecting pool forms the core area of visual connectivity, while Jinren Terrace becomes the transportation node with the highest accessibility. This design of “separation and connection” combines visual guidance with traffic flow, providing a layered spatial experience that stimulates visitors’ interest in exploration. Meanwhile, the historical development of Jin Ancestral Temple shows a clear trend of “growth”. From its early single function of worship, it gradually expanded into a complex architectural complex integrating worship, landscape, and belief, reflecting the changes in social, political, and cultural needs in different periods. The research results not only demonstrate the high degree of balance between the functionality and ornamental value of Jin Ancestral Temple’s buildings, but also reveal their unique value as cultural heritage in terms of spatial layout and aesthetic design. This paper provides a scientific basis for the protection and tourism development of Jin Ancestral Temple, and offers a new perspective on the combination of traditional architectural research and spatial analysis methods.

Network pharmacology unveils the active components and potential mechanism of traditional efficacy of Mugua.

Mugua is a Chinese herbal medicine derived from the dried mature fruit of Chaenomeles speciosa (Sweet) Nakai. This study aimed to dissect the active ingredients and mechanism of Mugua. In the present study, the active components of Mugua were collected and screened through databases combined with UPLC-Q/TOF-MS based qualitative analysis and literature mining, and their potential disease targets were predicted. Then, a network relationship diagram of "component-target-disease-efficacy" was constructed. Moreover, the key active components and core targets were analyzed by molecular docking and in vitro anti-inflammatory assays. The traditional efficacy of Mugua mainly corresponded to 4 diseases, namely, rheumatoid arthritis, diarrhea, edema, and emesis. After screening and comparison, it was found that IL-1β, IL-6, TNF, and epidermal growth factor receptor (EGFR) were the shared inflammatory targets of the 4 diseases. Gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment results showed that these targets were involved mainly in inflammatory responses and inflammation-related pathways, such as rheumatoid arthritis pathway and TNF signaling pathway. Network topology analysis revealed that succinic acid, cinnamic acid, citric acid, caffeic acid, gallic acid, ursolic acid, malic acid, betulinic acid, and oleanolic acid were the key active components, while IL-1β, IL-6, TNF, and EGFR were the shared core targets of these 4 diseases. These results suggested that Mugua could exert traditional efficacy through multi-component and multi-target synergistic mechanisms. Molecular docking results showed that all key active ingredients could autonomously bind to the shared core targets, and the in vitro anti-inflammatory results further confirmed that all the key active components had good anti-inflammatory activities. The present study found that Mugua mainly intervened in the inflammatory response and pathways by acting on key active components and core targets to exert traditional efficacy, providing a theoretical basis for further in-depth research.

Record-High BVDS p-Channel P++-GaN/P-GaN/GaN/AlN/Al0.3Ga0.7n MOS-HFETs with Drain Field-Plate Design

This work reports record-high three-terminal on- state drain-source breakdown voltage (BVDS ) of -735 V, superior on/off current ratio (Ion /Ioff ) of 2 × 106, and improved device performance of the p-channel p++- GaN/p-GaN/GaN/AlGaN metal-oxide-semiconductor hetero-structure field-effect transistors (MOS-HFETs) with drain-field plate (DFP) design. A reference MOS-HFET without DFP was fabricated and studied in comparison. High-k, wide-gap Al2O3 was deposited as the gate oxide and surface passivation by using a non-vacuum ultrasonic spray pyrolysis deposition (USPD) technique. Atomic force microscope (AFM), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), and capacitance-voltage (C-V) measurement were also performed to characterize the material and interface quality of the MOS-gate design. The present p-channel MOS-HFET design is promising for high-voltage complementary power-switching circuit application.The schematic device structures of the present p++-GaN/ p-GaN/GaN/AlN/Al0.3Ga0.7N MOS-HFETs without/with DFP (samples A/B) are shown in Fig. 1(a). The epitaxial layers for both samples were grown on a Si substrate by using a low-pressure metal-organic chemical vapor deposition (LP-MOCVD) system. The related schematic energy-band diagram was shown in Fig. 1(b), illustrating the formation of 2DHG by the heterostructural design. Standard lift-off and photolithography were applied to the device fabrication for the present sample with (without) DFP design. The AFM photos shown in Figs. 2 (a)-(c) compared the surface roughness after dry-etching, after the TMAH treatment, and after the further deposition of Al2O3 by USPD. The cross-sectional TEM photo of the Al2O3 oxide was shown in Fig. 2 (d). The XPS profile shown in Fig. 3 also verified the composition of the Al2O3 layer. Fig. 4 shows the C-V hysteresis measurement curves to confirm the improved interfacial quality by the Al2O3 passivation.Figs. 5(a)-(b) show the typical IDS -VDS curves and the transfer IDS /gm -VGS characteristics for the studied samples A and B at 300 K. The characterized three-terminal on- state drain-source breakdown voltage (BVDS ) andtwo-terminal off-state gate-drain breakdown voltage (BVGD ) were also compared in Fig. 6 and its inset. Due to the integrated device design as mentioned before, the present sample B (A) with (without) DFP has demonstrated superior maximum drain-source current density (IDS, max ) of -9.5 (-10.6) mA/mm at VDS = 20 V, on/off current ratio (Ion /Ioff ) of 2 × 106 (9.2 × 105), BVGD of 710 (520) V, and BVDS of -735 (-545) V, respectively. Enhanced gate modulation, improved current density, enhanced Ion /Ioff switching, and superior BVDS and BVGD performances have been successfully achieved. Comparisons of the IDS, max vs. Ion/Ioff benchmark of the present samples A and B with respect to other p- channel GaN-based devices were shown in Fig. 7. The present sample B has achieved the record-high BVDS of - 735 V with superior Ion /Ioff ratio of 2 × 106.The present p-channel GaN MOS-HFET designs with/without DFP have been successfully investigated. Through the integrated heterostructural/device designs, material/interface characterizations, and comparative device measurement, the present sample B has demonstrated superior performance with the highest BVDS record, so far. It is beneficial to high-voltage complementary power-switching IC applications. Figure 1

Grey correlation analysis of the main influencing factors of wax deposition of waxy crude oil and determination of pigging period based on dynamic analysis

Normal temperature gathering and transportation has significant advantages in reducing energy consumption and cost. Due to the high wax content of crude oil in carbonate reservoirs, obvious wax deposition will occur in the process of gathering and transportation at room temperature. In this paper, according to the component analysis results of crude oil on site, the HEATANALOGY wax deposition model was used to calculate the wax deposition of different gathering pipelines. The main influencing factors of wax deposition were analyzed by grey correlation method. Finally, according to the pigging mechanical balance model, the safe pigging period is derived, and the relationship diagram of different pipe diameters, throughput and ground temperature is drawn. The results show that the wellhead temperature has the greatest influence on the initial wax deposition position and the peak wax deposition position of the pipe section. The flow rate has the greatest influence on the maximum wax deposition thickness of the tube wall. According to the relationship between the working conditions and the pigging cycle, it can be found that with the increase of the throughput, the pigging cycle decreases first and then increases. With the increase of ground temperature, the pigging cycle increases.
