AbstractThe incorporation of data analytics in the healthcare industry has made significant progress, driven by the demand for efficient and effective big data analytics solutions. Knowledge graphs (KGs) have proven utility in this arena and are rooted in a number of healthcare applications to furnish better data representation and knowledge inference. However, in conjunction with a lack of a representative KG construction taxonomy, several existing approaches in this designated domain are inadequate and inferior. This paper is the first to provide a comprehensive taxonomy and a bird’s eye view of healthcare KG construction. Additionally, a thorough examination of the current state-of-the-art techniques drawn from academic works relevant to various healthcare contexts is carried out. These techniques are critically evaluated in terms of methods used for knowledge extraction, types of the knowledge base and sources, and the incorporated evaluation protocols. Finally, several research findings and existing issues in the literature are reported and discussed, opening horizons for future research in this vibrant area.
Improved content recommendation algorithm integrating semantic information
Authors: Huang Ran 
Published: May 2023

AbstractContent-based recommendation technology is widely used in the field of e-commerce and education because of its intuitive and easy to explain advantages. However, due to the congenital defect of insufficient semantic analysis of TF-IDF vector space model, the traditional content-based recommendation technology has the problem of insufficient semantic analysis in item modeling, fails to consider the role of semantic information in knowledge expression and similarity calculation, and is not accurate enough in calculating item content similarity. The items with semantic relevance in content can not be well mined. The research goal of this paper is to improve the semantic analysis ability of the traditional content-based recommendation algorithm by integrating semantic information with TF-IDF vector space model for item modeling and similarity calculation and proposed an improved content recommendation algorithm integrating semantic information. In order to prove the effectiveness of the proposed method, several groups of experiments are carried out. The experiments results showed that the overall performance of the proposed algorithm in this paper is the best and relatively stable. This verified the validity of our method.

Published: May 2023

Abstract
Research objective
Triadic patent (TP) families and Patent Cooperation Treaty (PCT) applications are often used as datasets to measure innovation capability or R&D internationalization, but their concordance is unclear, which is the main issue in this study.

Methods
We collect the global TP and PCT data from the Derwent Innovations Index (DII), and a total of 1,589,172 TP families and 4,067,389 PCT applications are retrieved. Based on International Patent Classification (IPC) codes, we compare these two big datasets in three parts: IPC distribution, IPC co-occurrence network, and nation-IPC co-occurrence network. In order to understand the overall similarities and differences between TP and PCT, we make the basic statistics of the global data and w-core defined based on the w-index. Furthermore, the w-cores are visualized and the global similarities are calculated for the detailed concordance and differences.

Findings
The result shows that the w-core is suitable to select the core part of big data and TP and PCT get high concordance. Meanwhile, in technological convergence, some specific technical fields (e.g. chemistry, medicine, electronic communication, and lighting technology) and countries/regions (e.g. Germany, Japan, China, and Korea), there are a few differences.

Practical implications
TP families are very similar to PCT applications in terms of reflecting innovation capability or R&D internationalization at a macro level, but when it comes to technological convergence, specific research topics, and countries/regions, the choice may depend on the purpose of the research.

Published: May 2023

AbstractThis article discusses an effective technique for detecting abnormalities in Hajj crowd videos. In order to guarantee the identification of anomalies in scenes, a trained and supervised FCNN is turned into an FCNN using FCNNs and temporal data. By minimizing computational complexity, incorrect movement detection is utilized to achieve high performance in terms of speed and precision. This FCNN-based architecture is designed to handle two primary tasks: feature representation and the detection of incorrect movement outliers. Additionally, to overcome the aforementioned issues, this research will generate a new crowd anomaly video dataset based on the Hajj pilgrimage scenario. On the proposed dataset, the UCSD Ped2, Subway Entry, and Subway Exit datasets, the proposed FCNN-based technique obtained ultimate accuracy of 100%, 90%, 95%, and 89%, respectively. Additionally, the ResNet50-based technique achieved ultimate accuracy of 96%, 89%, 94%, and 92%, respectively, for the proposed dataset, the UCSD Ped2, Subway Entry, and Subway Exit datasets.

Authors: Asemi Asefeh , Asemi Adeleh , Ko Andrea 
Published: May 2023

AbstractThe proposed model is an adaptive neuro-fuzzy inference recommender system that utilizes customer investment service feedback and fuzzy neural inference solutions to generate personalized investment recommendations. The model is designed to support the investment process for the customers and takes into consideration seven factors to implement the proposed investment system model through the customer or potential investor data set. These include demographic data and investment type. The model is divided into three main phases: data gathering, data analysis, and decision-making. In the data gathering phase, initial data is collected through a web-based platform, and in the data analysis phase, the potential investors' demographic criteria are extracted and grouped, and the types of investments are then clustered. The output obtained is transferred to the ANFIS layer, and investment-type recommendations are extracted for each group of potential investors. Investor feedback is received to improve and develop the system. JMP and MATLAB are used to propose the model, which serves as a framework for investment recommender systems. It demonstrates how to use this framework to offer pertinent and precise recommendations for the best sort of investment type to potential and present investors by combining the expertise of the experts and the demographic information of potential investors. Overall, this paper provides a new, novel model for investment recommender systems, which can assist investment companies, individual investors, and fund managers in their investment decisions.

Published: May 2023

Abstract
Background
Although vasopressor and sedative agents are commonly used within the intensive care unit to mediate systemic and cerebral physiology, the full impact such agents have on cerebrovascular reactivity remains unclear. Using a prospectively maintained database of high-resolution critical care and physiology, the time-series relationship between vasopressor/sedative administration, and cerebrovascular reactivity was interrogated. Cerebrovascular reactivity was assessed through intracranial pressure and near infrared spectroscopy measures. Using these derived measures, the relationship between hourly dose of medication and hourly index values could be evaluated. The individual medication dose change and their corresponding physiological response was compared. Given the high number of doses of propofol and norepinephrine, a latent profile analysis was used to identify any underlying demographic or variable relationships. Finally, using time-series methodologies of Granger causality and vector impulse response functions, the relationships between the cerebrovascular reactivity derived variables were compared.

Results
From this retrospective observational study of 103 TBI patients, the evaluation between the changes in vasopressor or sedative agent dosing and the previously described cerebral physiologies was completed. The assessment of the physiology pre/post infusion agent change resulted in similar overall values (Wilcoxon signed-ranked p value > 0.05). Time series methodologies demonstrated that the basic physiological relationships were identical before and after an infusion agent was changed (Granger causality demonstrated the same directional impact in over 95% of the moments, with response function being graphically identical).

Conclusions
This study suggests that overall, there was a limited association between the changes in vasopressor or sedative agent dosing and the previously described cerebral physiologies including that of cerebrovascular reactivity. Thus, current regimens of administered sedative and vasopressor agents appear to have little to no impact on cerebrovascular reactivity in TBI.

Published: May 2023

Abstract
Background
This study was established to assess cysteamine’s cytotoxic effect alone and in combination with various intracanal medications on fibroblast cells, because the biocompatibility of intracanal medication is considered one of the main factors that affect the selection of specific medication for usage near vital periodontal tissues.

Methods
All tested medications were prepared in a solution form. Cysteamine preparation was prepared at 200 mg/ml concentration in distilled water. The chlorhexidine–cysteamine combination was prepared by dissolving 10 mg/ml of cysteamine in chlorhexidine. Calcium hydroxide–cysteamine combination was prepared by dissolving 10 mg/mL of cysteamine in a saturated solution of calcium hydroxide (CaOH). Triple antibiotic paste (TAP)–cysteamine combination was prepared by dissolving 10 mg/mL of cysteamine in triple antibiotic paste (TAP). BHK cells were seeded in well-microtiter plates. The testing materials were filtrated using a 0.22 μm syringe filter. BHK-21 cells precultured well plates were treated with descending 12-fold serially diluted medications at 37 °C for 24 h. Residual living cells were treated with 25 μl of MTT dye. MTT was discarded, and then, dimethyl sulfoxide was added as 50 μl/well. The absorbance was conducted at 570 nm. The mean optical density and 50% cell growth inhibition (IC50) were calculated. Cell viability data showed parametric distribution, so they were analyzed using one-way ANOVA followed by Tukey’s post hoc test for intergroup comparisons and repeated measures ANOVA followed by Bonferroni’s post hoc test for intragroup comparisons. The significance level was set at p ≤ 0.05.

Results
Viability % and IC50 results showed that triple antibiotic paste (TAP)–cysteamine combination had the lowest cytotoxicity level compared to other intracanal combinations followed by cysteamine and the highest cytotoxicity was with chlorhexidine–cysteamine combination.

Conclusions
Triple antibiotic paste (TAP)–cysteamine combination was the safest drug compared to other drug combinations with cysteamine, so it needs more research to detect its acceptance with stem cells and its effect on defense mechanisms during healing.
Persistent, viable seedbank buffers serotinous bishop pine over a broad fire return interval
Authors: Bisbing Sarah M. , Urza Alexandra K. , York Robert A. , Hankin Lacey E. , Putz Tessa R. 
Published: May 2023

AbstractBackgroundIn ecosystems where fire has been excluded, pyrosilviculture can restore some processes historically maintained by fire while mitigating risk where fire is inevitable. Pyrosilviculture in crown fire-adapted forests is, however, limited by insight into the temporal window of fire return matching canopy seedbank development. Here, we characterized demographic responses to fire and non-native pine pitch canker infection in a chronosequence of serotinous bishop pine stands burned at high-severity to quantify (1) temporal patterns of seedbank development given seed viability and density, cone production, and tree density, and (2) pine pitch canker incidence across tree ages and sizes to assess how infection might impact stand and seedbank development. We use our findings to elucidate pyrosilvicuture as a means of restoring fire given practical challenges of reintroducing high-severity fire in crown-fire adapted forests embedded within wildland urban interfaces (WUI).ResultsBishop pine produces an abundant, viable seedbank within eight years that persists across developmental stages and age classes. Seed abundance and viability are exceptionally high at even the earliest age (median > 600,000 seeds ha− 1 and 97% viability at 6 years) and remain high, with the oldest stands (36 years) maintaining median densities of > 500,000 seeds ha− 1and viability of 95%. We additionally learned that pine pitch canker infection is most severe during the sapling stage (8–10 years post-fire), likely altering stand development trajectories as well as potentially limiting recruitment, and thus the aerial seedbank, into the canopy.ConclusionsIn bishop pine and equally-fecund serotinous species, pyrosilviculture appears a viable management tool across a broad fire return window given the early development and persistence of a robust, viable seedbank, allowing managers flexibility in restoring fire to promote forest persistence while simultaneously mitigating wildfire risk. Moreover, pyrosilviculture in pine pitch canker infected stands may also provide disease mitigation. Although the long-term effects of pine pitch canker infection remain unknown, bishop pines’ viable, persistent seedbank suggests that managers can ignite prescribed fire across a broad return interval — as short as eight years and as long as several decades — to promote bishop pine persistence, mitigate disease infection rates, and reduce wildfire risk in WUI-adjacent ecosystems.
Depression, poor sleep quality, and diabetic control in type 2 diabetes patients at Sunyani Regional Hospital, Ghana: a case–control study
Authors: Agyekum Jennifer Adjepong , Gyamfi Thomas , Yeboah Kwame 
Published: May 2023

Abstract
Background
Diabetes patients are at risk of developing mental health comorbidities such as depression and poor quality of sleep. These conditions can affect diabetic management, including glycemic and plasma lipid control to optimal levels. We investigated the association between diabetic control and the presence of depression and poor sleep quality in type 2 diabetes (T2DM) patients at Sunyani Government hospital in Ghana. Using a case–control design, we recruited 200 T2DM patients and compared them to 160 non-diabetic controls. The presence of depression was assessed using the Patient Health Questionnaire (PHQ)-9 and sleep quality using the Pittsburgh Sleep Quality Instrument (PSQI). Blood samples were collected to measure glycated hemoglobin (HbA1c) levels and plasma lipid profiles. Poor glycemic control was defined as HbA1c > 7%, depression as PHQ-9 score > 9 and poor sleep quality as PSQI score ≥ 5.

Results
T2DM patients had a higher prevalence of depression (31.5% vs 10.6%, p < 0.001) and poor sleep quality (64% vs 40%, p < 0.001) compared to non-diabetic controls. Glycemic control was not associated with depression and poor sleep quality in T2DM patients. Depression was associated with increased odds of hypercholesteremia [OR (95% CI) = 10.71 (2.64–43.41), p < 0.001] in non-diabetic controls and poor sleep quality was associated with increased odds of low HDL cholesterol in T2DM patients [3.2 (1.38–7.48), p = 0.007] and hypertriglyceridemia in non-diabetic controls [2.54 (1.15–8.51), p < 0.001].

Conclusion
In our study population, depression and poor sleep quality were common in T2DM patients compared to non-diabetic controls. Depression and poor sleep quality were associated with abnormalities in serum lipid levels, but not glycemic control.
Technological environment and sustainable performance of oil and gas firms: a structural equation modelling approach
Authors: Akhimien Okharedia Goodheart , Adekunle Simon Ayo 
Published: May 2023

AbstractThis study draws from the dynamic capabilities theory to examine how sustainable performance measured along with financial, environmental, and social performance are impacted by technology infrastructure, technology knowledge, and technology applications. Copies of the questionnaire were administered to the Operations and Information Technology department staff of selected oil firms in the Niger Delta region of Nigeria. Out of the three hundred (300) copies of the questionnaire administered, two hundred and forty-three (243) were validly filled. Sixteen (16) of the responses were deleted due to the presence of an outlier in the dataset. The remaining two hundred and twenty-seven (227) responses were used for data analyses. The research model was estimated using structural equation modelling to establish relationships among the variables. The study found that technology infrastructure has a positive but insignificant impact on the sustainable performance of oil and gas firms. However, technology knowledge and application positively and significantly impact sustainable performance. The study recommends that oil and gas companies continually employ, reward, and train individuals to absorb and utilize acquired technologies to develop a standard for addressing the social and environmental problems in the Niger Delta region.
The so-called Y-type urethral duplication: anatomical insights through controversial terminology
Authors: AbouZeid Amr Abdelhamid , Mohammad Shaimaa Abdelsattar 
Published: May 2023

Abstract
Background
Y-type urethral duplication is a term frequently used to describe a rare condition in the male associated with double urinary stream: a weak interrupted urinary stream through a hypoplastic penile urethra, while the main urine flow is through the anus/perineum via accessory posterior channel. Fortunately, the advent of MRI has provided a powerful tool to study these anomalies in depth and on multiple planes.
The study included boys presenting with abnormal micturition through the anus beside weak interrupted urine stream through the penis. Investigations included pelviabdominal ultrasound to screen for possible associated upper urinary tract anomalies, conventional contrast X-ray studies, and pelvic MRI.

Results
During the period between 2016 through 2021, the study included two newly diagnosed cases with abnormal communication between the lower urinary tract and the anus (the so-called Y-type urethral duplication), in addition to one previously reported case whose preoperative imaging studies (including pelvic MRI) were available for analysis. Different surgical solutions have been applied for each case. Hypoplasia was not only restricted to the penile urethra but also affected the corporeal bodies of the penis with variable degrees. In two cases, only a single corporeal body could be identified. In another case, the three corporeal bodies were present but appeared distorted (irregularities and interruption of corporeal bodies).

Conclusion
In our present study, pelvic MRI examination clearly unveiled significant degrees of corporeal dysgenesis among cases diagnosed as Y-type urethral duplication that would strongly suggest these cases to belong to the same disease spectrum of penile dysgenesis/agenesis.

Abstract
Background
The use of donor hearts with valvular disease has been considered debatable in heart transplantation for many years. However, few reports indicate successful heart transplantation using donor hearts with mitral regurgitation that underwent mitral valve repair on the back bench.

Case presentation
We report two cases of a 38-year-old and a 48-year-old woman with implantable left ventricular assist devices who underwent heart transplantation at our institution. Transthoracic echocardiography of donor hearts just before the explant revealed that each donor heart had preserved cardiac function and significant mitral regurgitation due to mitral posterior leaflet prolapse and annular dilatation, respectively. Bench mitral valve repair was accomplished using triangular resection for one patient and annuloplasty for the other. This was followed by confirmation of excellent mitral leaflet coaptation without residual mitral regurgitation. Transthoracic echocardiography and right heart catheterization performed 6 months after transplantation clarified the favorable cardiac function of each transplanted heart without mitral regurgitation recurrence.

Conclusions
Efficient utilization of donor hearts with mitral regurgitation may be acceptable when the cardiac function of donor hearts with mitral regurgitation is preserved and heart transplantation, including bench mitral valve repair, is feasible within an acceptable ischemic time.
Metoda oceny wartości i kształtowania krajobrazu oraz jej zastosowanie dla wybranych małych miast województwa pomorskiego objętych obszarami chronionego krajobrazu
Authors: Kistowski Mariusz 
Published: May 2023

The aim of the research was to delimit landscapes, identify their features, analyse their frequency and assess their value, as well as to provide some recommendations on their development and protection. The research area covers four small towns in the Province of Pomerania (Człuchów, Gniew, Prabuty and Dzierzgoń), where protected landscape areas have been established. A wide range of numerical data was used, especially on land cover and relief, as well as on cultural assets. Initially, what was applied was the methodology proposed for performing a landscape audit of the provinces. However, it was significantly modified during the course of the study. Use was made of two approaches to landscape delimitation: one based on land cover and a comprehensive one, allowing for a type of relief, a degree of anthropisation and the texture of a landscape. The first approach made it possible to assess the degree of landscape anthropisation, and the second one enabled the evaluation of the landscape when the criterion of the value of landscape exposure elements was added. The degrees of anthropisation and landscape value vary in the investigated cities, with greater differences in the parts covered by protected landscape areas than in those located in their surroundings. There are also significant differences in the scope and extent of proposed conservation measures. The research – in addition to modifying the previously proposed method – as also found that some of the protected areas have landscapes of lower value than their neighbourhoods, so it can also support planning changes in the existing boundaries or creating new protected areas.
