The Prediction of Road Condition Value during Maintenance Based on Markov Process

The first step in the road handling effort is to survey to get an accurate road condition value to take correct action in implementing maintenance. As pavement performance is known to be probabilistic, various levels of uncertainty must be assumed. Modern pavement management methods are ineffective without an effective model to predict pavement performance. Discrete-time Markov chains are the most widely used probabilistic models, and examples from different countries worldwide can be found in pavement management systems. This research aims to predict the value of road conditions during maintenance and compare road assessments with real conditions during road maintenance using the IRI, SDI, and PCI methods using the Markov process. The analysis method used is to collect secondary data from related departments and carry out direct data collection in the field to obtain condition values based on IRI, SDI, and PCI to forecast by making a pavement condition prediction model based on the Markov process and then assessing road conditions by comparing the three index values with the slightest deviation value. The analysis showed that the average value of road conditions with the IRI indicator is 4.45, which is moderate, and the most negligible difference between the probability distribution of pavement condition prediction modeling and the actual survey results was the IRI (International Roughness Index) method. This model is closest to the actual conditions during implementation, with a difference value of 5.7%.

The output frequency of the humidity detection circuit is measured by the single-chip microcomputer, and the current ambient humidity can be obtained by substituting the result into the above formula, that is, when the output frequency dimension of the circuit is 6853Hz, the ambient humidity is 40%. Through the application of this system, the inefficient and extensive manual management method of the computer experimental teaching center is completely solved, so that it can bring more intelligent and efficient services to the teachers and students of the whole school, so as to comprehensively promote the experimental teaching of the school.

Importance of parental anxiety in management of developmental breast conditions in children: A study with a prospective hierarchical regression model.

The parent is the most critical link and decision-maker between the patient and the healthcare provider in treating many pediatric diseases. This entity is essential for the management of pediatric breast diseases for which the rate of surgical intervention is known to be very low. Although previous publications have emphasized that pediatric breast diseases may cause alarming anxiety in parents, the demographic factors that influence this anxiety have not been investigated. Even if practitioners complete patient management with appropriate procedures, treatment is incomplete if the questions remain unanswered. In this observational prospective study, we investigated the demographic factors that affect parental anxiety, which should be prioritized to prevent incomplete management. The Beck Anxiety Inventory score (BAS) created by the parents of 409 boys and girls aged 0 to 17 with breast conditions was recorded at the diagnosis, termination of treatment, and final control stages. A 2-stage hierarchical logistic regression model was applied to show how strongly the demographic characteristics of parents and their children predicted the parental BAS. Of the demographic characteristics, there was a significant correlation (P < .05) between the patient's sex, age, developmental period, Tanner stage, referral status, management method, family's place of residence, economic distress, and BAS. However, according to the 2-stage hierarchical regression model, only 3 demographic characteristics, the patient's gender, place of residence, and method used in patient management, significantly predicted BAS (P < .05, ΔR2 = .35). Among the many factors that affect anxiety experienced by parents whose son or daughter has breast problems, the gender of the child, place of residence of the family, and management methods used by the practitioner are demographic characteristics that should be taken into consideration.

Development of a real-time cattle lameness detection system using a single side-view camera

Recent advancements in machine learning and deep learning have revolutionized various computer vision applications, including object detection, tracking, and classification. This research investigates the application of deep learning for cattle lameness detection in dairy farming. Our study employs image processing techniques and deep learning methods for cattle detection, tracking, and lameness classification. We utilize two powerful object detection algorithms: Mask-RCNN from Detectron2 and the popular YOLOv8. Their performance is compared to identify the most effective approach for this application. Bounding boxes are drawn around detected cattle to assign unique local IDs, enabling individual tracking and isolation throughout the video sequence. Additionally, mask regions generated by the chosen detection algorithm provide valuable data for feature extraction, which is crucial for subsequent lameness classification. The extracted cattle mask region values serve as the basis for feature extraction, capturing relevant information indicative of lameness. These features, combined with the local IDs assigned during tracking, are used to compute a lameness score for each cattle. We explore the efficacy of various established machine learning algorithms, such as Support Vector Machines (SVM), AdaBoost and so on, in analyzing the extracted lameness features. Evaluation of the proposed system was conducted across three key domains: detection, tracking, and lameness classification. Notably, the detection module employing Detectron2 achieved an impressive accuracy of 98.98%. Similarly, the tracking module attained a high accuracy of 99.50%. In lameness classification, AdaBoost emerged as the most effective algorithm, yielding the highest overall average accuracy (77.9%). Other established machine learning algorithms, including Decision Trees (DT), Support Vector Machines (SVM), and Random Forests, also demonstrated promising performance (DT: 75.32%, SVM: 75.20%, Random Forest: 74.9%). The presented approach demonstrates the successful implementation for cattle lameness detection. The proposed system has the potential to revolutionize dairy farm management by enabling early lameness detection and facilitating effective monitoring of cattle health. Our findings contribute valuable insights into the application of advanced computer vision methods for livestock health management.

THE ENHANCEMENT OF THE CAPACITY OF COMMUNITIES AROUND THE FOREST IN PRODUCING ANIMAL FEED THROUGH SILAGE-MAKING TRAINING

Kemutug Lor Village, located on the southern slope of Mount Slamet, boasts various potentials, including livestock farming and the utilization of forest resources. One method of forest area management undertaken by the community is the development of an agrosilvopastoral model, which integrates seasonal crop cultivation with forestry and livestock activities. This community service initiative aims to enhance the community's capacity in processing odot grass into silage as high-quality animal feed. The approach utilized in this activity is asset-based community development. Goat farming and the development of the agrosilvopastoral model in the forest area, initiated by the community, serve as the foundation for this community service activity. A total of 23 individuals from the community were equipped with technical skills in silage production using odot grass as the raw material. This endeavor contributes to the utilization of abundant odot grass in Kemutug Lor and the enhancement of livestock feed management within the community. Evaluation results indicate an increase in the community's knowledge of silage production after receiving training materials. Furthermore, subsequent to the conclusion of the training activity, the community engages in periodic practice and production of silage as supplementary animal feed.

Management of breakthrough bleeding in transgender and gender diverse individuals on testosterone

While many transgender and gender diverse individuals rapidly achieve amenorrhea on testosterone, emerging data has identified that breakthrough bleeding (BTB) can occur in up to one third of individuals with long term use. BTB can worsen dysphoria and patients may seek management to reattain amenorrhea. Because of this, there is a need to assess efficacy of management approaches. The primary aim of the study was to evaluate methods used by patients and their providers to manage BTB which arises after one year of testosterone use. Secondary aims included describing the diagnostic approaches to BTB, and proposing an algorithm for classification and management of BTB in this patient population. This was an IRB-approved single tertiary center, retrospective chart review of transgender and gender diverse individuals on testosterone gender affirming hormone therapy who experienced BTB after one year of use. Charts were reviewed to determine patient characteristics, testosterone use, and BTB management approaches. Of the 96 individuals who had been on testosterone for one year and experienced BTB, 97% (n=93) engaged in at least one approach to management. The mean age at initiation of testosterone was 21.9 (SD 5.4) and the median duration of time on testosterone was 54.5 months (IQR 33.5,82). Only 16% (n=15) were using menstrual suppression at the time of their BTB episode. BTB was successfully managed in 77 (79%), following between 1-4 attempted approaches. More than half of management attempts (63%) were successful on the first try. When management approaches were analyzed independently, the range of success associated with any particular approach was between 33-100%. Other than hysterectomy, which was fully successful at managing BTB, no approach was significantly better than no intervention. This was true both for individuals who did and did not bleed with missed testosterone doses. Regardless of what approach was used, after a failed attempt, the next attempt was successful in more than half of individuals. Of the 16 who underwent hysterectomy, one did so in part as a first line approach to manage BTB. In this study, use of medical management methods was not found to be superior to observation alone in the management of BTB. In the absence of data supporting superiority of any method, we recommend tailoring method attempts to patients' goals.

Comparison of Treatment Outcomes of Different Immobilized Finger Positions After Repair of Flexor Tendon Rupture in Zones I and II: A Nonrandomized Controlled Trial With Historical Control Group.

Introduction The position of finger immobilization after flexor tendon rupture repair is changed to the extended position to prevent flexion contracture of the interphalangeal (IP) joint. However, in Strickland's assessment, We believe that a reduction in TAF (total active flexion) affects the outcome and that extension fixation is not necessarily the primary focus.For example, there are management methods that swap the fixed position between day and night. It is assumed that some effect is sought by placing the fingers in the flexed position. That is, the method of fixation is currently selected at individual facilities through twists and turns; however,the indications and criteria for selecting finger fixation positions are ambiguous, and they are apparently subject to the experience of therapists. This study aimed to characterize follow-up outcomes of flexion and extension fixation after zones I and II flexor tendon rupture repair. Methods This nonrandomized controlled trial with historical controls included 25 patients with flexor tendon ruptures of 30 fingers. The flexion fixation group consisted of 12 patients (n=16 fingers) and the extension fixation group consisted of 13 patients (n=14 fingers). The group with flexion fixation comprised patients who slept with their injured fingers in the flexed position (intervention group). The group with extension was retrospectively selected between April 2017 and March 2019, who slept with their injured finger in the extended position (historical control group). Strickland assessments of the range of motion (ROM) of each joint at the conclusion of hand therapy, the ratio of total active motion of the repaired, to the healthy finger (%TAF), and IP joint extension limitation angles were compared using Mann-Whitney U tests. Ratios of excellent and good ratings based on the Strickland assessment were compared using Fisher exact tests. Result The results of the Strickland assessment showed excellent or goodoutcomes for 22(73%) of 30 fingers, which was in line with our previous findings. Strickland ratings of excellent were achieved in seven (44%) of 16 fingers and four (28%) of 14 fingers in the groups with flexion and extension fixation, respectively. The outcomes for two (22%) of 16 fingers and seven (78%) of 14 fingers in the groups with flexion and extension fixation were, respectively, rated asgood. The proportion of patients rated as excellent was significantly higher in the group with flexionthan extension fixation (p=0.040). The %TAF and the active flexion angle of the distal interphalangeal (DIP) joint were higher in the group with flexionthan extension fixation (p=0008 and p=0.025, respectively). Furthermore, the total angle of the IP joint limit of extension did not significantly differ between the groups. Conclusion Flexion fixation after flexor tendon rupture achieved an excellent Strickland rating and was more effective than extension fixation, especially in terms of the active flexion ROM of the DIP joint. Flexion fixation might be an alternative to extension fixation because the range of flexion should be greater and might provide a range of finger extension motion equivalent to that of extension fixation.

A Study of Predictors of Failure of Nonoperative Management of Ileocolic Intussusception in Children.

Surgery remains the mainstay in treating intussusception in developing nations. A correspondingly high bowel resection rate exists despite a shift to nonoperative reduction in high-income countries. We aimed to study the clinical profile of the patients with intussusception presenting to our hospital and to assess the clinical and radiological predictors of success or failure of nonoperative management of intussusception. This prospective study was conducted in the Department of Pediatric Surgery over a period of 3 years and included a total of 118 patients who presenting to our emergency division with features suggestive of intussusception and were managed accordingly either with hydrostatic reduction or by surgical intervention. We observed that the majority of the patients were males (65.5%). The mean age was 13.54 months. Intermittent pain was the most common symptom. Both pain and vomiting did not affect the outcome. Lab parameters like raised total leukocyte counts (TLC), C-reactive protein (CRP) and lactate levels were significantly associated with failure of hydrostatic reduction. Patients with air fluid levels on X-ray were more likely to end up in surgery. Ultrasound findings of bowel wall edema, aperistaltic gut loops and a pathological lead point was associated with failure of hydrostatic reduction as well. The overall success rate of hydrostatic reduction was 85.5%. Hydrostatic reduction of intussusception is a safe and effective method of management of intussusception whenever indicated. Factors that might reduce the chance of its success include continuous pain, irritability, tenderness, deranged lab parameters like TLC, CRP and lactate levels, air fluid levels on X-ray, bowel wall edema, aperistalsis and the presence of a lead point.

Association Between Adherence to a 3-Month Cardiac Rehabilitation Program and Long-Term Clinical Outcomes in Japanese Patients With Cardiac Implantable Electronic Devices.

The objective of this study was to evaluate the association between comprehensive cardiac rehabilitation (CCR) completion and long-term clinical outcomes in patients with cardiac implantable electronic devices (CIED). This retrospective cohort study included 834 patients with CIED who participated in CCR, which included a cardiopulmonary exercise test or 6-min walk test. Patients with a left ventricular ejection fraction ≤40%, predicted peak oxygen uptake ≤80%, or B-type natriuretic peptide level ≥80pg/mL were eligible. The primary outcome was all-cause death. After excluding 241 patients with duplicate records and 69 who underwent CCR in the outpatient department, the data of 524 patients were analyzed. Mean age was 64±15yr, 389 (74%) patients were men, left ventricular ejection fraction was 31±15%, and 282 (54%) patients had a history of hospitalization for worsening heart failure.. Of the patients referred for CCR, 294 (56%) completed the program, and an additional 230 patients started but did not complete CCR. Over a 3.7-yr median follow-up period, all-cause deaths occurred in 156 (30%) patients. Completers had lower all-cause death rates than non-completers (log-rank 15.77, P<.001). After adjusting for prognostic baseline characteristics, completers had 58% lower all-cause death risks than non-completers (HR=0.42; 95% CI, 0.27-0.64, P<.001). Three-mo CCR program completion was associated with lower death risks in patients with CIED. New programs or management methods are needed to decrease death risks, especially for those who cannot complete CCR programs.

Patterns of neurogenic lower urinary tract dysfunction management and associated factors among Chinese community-dwelling individuals with spinal cord injury

To identify different patterns of neurogenic lower urinary tract dysfunction management among Chinese community-dwelling individuals with spinal cord injury and explore the factors associated with latent classes. This was a cross-sectional study conducted in communities throughout China Mainland. Participants were recruited through the China Association of Persons with Physical Disability and a total of 2582 participants was included in the analysis. The data were collected by a questionnaire consisting of socio-demographic factors, disease-related factors, and a list of 8 bladder management methods. Latent class analysis was used to identify different latent classes of neurogenic lower urinary tract dysfunction management. Then the multinomial logistic regression was applied to analyze the relationship between neurogenic lower urinary tract dysfunction management patterns and socio-demographic and disease-related factors. Neurogenic lower urinary tract dysfunction management pattern among community-dwelling individuals with spinal cord injury was divided into four latent classes: “urinal collecting apparatus dominated pattern” (40.3%), “bladder compression dominated pattern” (30.7%), “intermittent catheterization dominated pattern” (19.3%) and “urethral indwelling catheterization dominated pattern” (9.6%). Multinomial logistic regression analysis found that the employment status, residential region, nursing need, payment method for catheterization products, hand function, time since spinal cord injury, urinary incontinence and concerns about social interaction affected by urination problems were significantly associated with latent classes. Only 19.3% of people used the intermittent catheterization as their main neurogenic lower urinary tract dysfunction management method. More attention needs to be paid to the promotion of the standardization process of intermittent catheterization in community-dwelling individuals with spinal cord injury. The associated factors of the four classes can be used for tailored and targeted interventions to increase the use of intermittent catheterization.

Geochemical characteristics, source analysis, influencing factors, and reserves of soil Selenium in Wuming, Guangxi, China.

Although selenium (Se) reserves are crucial for the development and exploitation of Se-rich resources in karst soil areas, research on these reserves is still limited. A comprehensive study was conducted in a typical karst region known for its Se richness. A total of 12,547 surface soil samples, 134 deep soil samples, and 60 soil profiles from various locations were systematically collected. The findings showed that the Se content in the surface soil ranged from 0.073 to 9.04mg/kg, with a baseline level of 0.84mg/kg. This underscores the high background level and moderate variability in the region. Surface soil Se exhibited a notable positive correlation with deep soil Se, and an inverse correlation with pH (p < 0.01). One-way analysis of variance indicated that land formations and soil structure were the primary determinants affecting the concentration of Se in the topsoil (p = 0.000), with parent rock type and land-use type following closely (p = 0.003). In addition, the study included an investigation of soil Se variations with depth using 60 soil profiles. Through this analysis, it was revealed that Se content exhibited an exponential change with depth. Multiple integrations were employed to derive formulas for calculating Se reserves in the 0-200cm depth range. Following these calculations, the estimations of Se stockpile across diverse types of source materials, varieties of soils, and land management methods were determined, highlighting the findings using a passive construction. This paper lays the groundwork for advancing the extraction and application of Se.

Risk Management and Different Financial Approaches to Reduce Business Risk

This article examines three different risk management methods: asset hedging by shorting stocks, cash flow hedging using forward contracts, and futures contracts. The article explains each method's rationale, application, advantages, and disadvantages. By presenting and explaining these methods, this study aims to help readers gain insights into their effectiveness in managing risk in different types of transactions. The content of the article supports the readers to have a better understanding and gives some strategies for risk management, and provides guidance for decision-makers to mitigate potential risks in their financial operations. Asset hedging by shorting stocks involves selling borrowed stocks in anticipation of a decline in their price, thereby offsetting the potential loss of a declining asset. This strategy allows an investor to profit from a decline in stock prices. Cash flow hedging through forward contracts involves entering into an agreement to buy or sell an asset at a pre-determined future price, thereby reducing the risk of adverse price movements and ensuring a stable cash flow. On the other hand, futures contracts are standardized agreements to buy or sell an asset at a future date, are traded on public markets, provide legal protection for both parties through financial intermediaries, and allow investors to lock in prices. While these risk management methods have obvious advantages, such as potential gains to offset the risk of asset depreciation during market downturns, protection against adverse price movements, and price stabilization, they also have inherent risks and limitations that need to be carefully considered.

A Comparison of the Frequency and Intensity of Standardized Precipitation Index (SPI) and the Rainfall Anomaly Index (RAI) during the Meteorological Drought across Harohar-Punpun Basin (India)

The term "drought" applies to a prolonged period when there is a water shortage because of insufficient precipitation, an excessive rate of evaporation, and excessive use of water from reservoirs and other storage, including ground water. It is a slow-onset phenomenon that can have significant social, economic, and environmental impacts. Both the frequency and severity of droughts are increasing globally due to manmade and natural factors. This study looked at how well SPIs (3, 6, 12-month time scales) and RAI (Rainfall Anomaly Index) performed at identifying drought occurrences over a period of 70 years (1951 to 2021) in India's Agro-Ecological Zones. The RAI and SPI values were computed using rainfall data from 9 meteorological stations located throughout the Harohar- Punpun Basin. According to the results, the RAI is more capable than SPIs in detecting historical records of actual occurrences. Additionally, RAI is more effective than SPIs for determining both short- and long-term droughts. Since RAI can better capture the true nature of the drought situation in the Harohar-Punpun Basin, it appears to be more responsive to drought circumstances. The primary causes of drought, according to the study, include minor variations in precipitation, willful ground water removal, changing cropping patterns, and substantial changes in land use. Regional planners and administrators will surely find use for this scientific study and integrated watershed management methods for sustainable water resource management, particularly for this region.

Living with wolves: A worldwide systematic review of attitudes.

This systematic review of peer reviewed articles on attitudes towards gray wolves (Canis lupus), shows that attitudes are mainly measured either by mean values of attitudes or by proportional differences in attitudes. This may impact on how attitudes are perceived and interpreted across studies and areas. However, independent of method used, we found that people living in areas where wolves always have existed, are more negative towards wolves compared to people living in areas where there are no wolves, or where wolves have recovered after years of absence. People who express fear, or being directly affected by having wolves, such as farmers and hunters, report more negative attitudes compared to other groups of respondents. For wolf conservation we recommend politicians and management authorities to prepare local societies of the different consequences of living in wolf areas. We recommend using dialogues and conflict management methods to minimize the level of conflicts.

An investigation on nurses’ competencies and practices regarding enteral tube medication administration: a cross-sectional study

Background: understanding how healthcare professionals correctly administer medications through enteral routes is necessary to reduce patient morbidity and mortality. The study’s objective is to evaluate nurses’ competencies and management methods in administering oral medications to hospitalized patients who have enteral feeding tubes. Materials and Methods: an observational cross-sectional study involving nurses employed at the University Hospital for at least six months. A survey consisting of 16 questions related to medication dilution, pharmaceutical form management, and enteral medication administration techniques was administered. Results: a total of 218 nurses were recruited, with a mean age of 30.95 years (SD 6.15), of whom 132 (60.5%) were female, and 173 (78.9%) held a bachelor’s degree. Approximately half of the responses (49.3%) were incorrect. Conclusions: nurses should improve their knowledge regarding enteral medication administration. Nurses are responsible for pharmacological management, and their level of knowledge directly impacts the health and safety of these patients. Therefore, specific training addressing the identified gaps would be appropriate.

Evaluation of Copper Sulfate Electroplating Solution and Film Using a New Method of Fluorescence Measurement

Control of plating bath conditions is an important issue on production lines. In this research, we developed a method for measuring and evaluating plating solutions using Janus Green B (JGB), a common additive, as a probe. It was discovered that when electricity was applied to a copper sulfate electroplating solution containing JGB as an additive, red fluorescence was generated. This is because the azo group of JGB is reductively cleaved by monovalent copper (Cu(I)) to produce a phenazine dye with red fluorescence. The fluorescence intensity depended on the energization current and time and was proportional to the concentration of JGB added. The fluorescence intensity indicates the rate of decrease in the concentration of JGB and can predict the deterioration of the quality of the plated film produced with the solution in a very early stage, and especially the occurrence of unevenness. Fluorescence is a simple and sensitive method of measurement that facilitates on-time and in situ measurement and evaluation of plating baths at the production site and is a useful method of bath management.

NONLINEAR DYNAMICS METHODS APPLICATIONS TO PRODUCT LIFECYCLE MANAGEMENT

The research being carried out is aimed at applying nonlinear dynamics methods in product life cycle management to improve communication between processes and achieve environmental sustainability. The purpose of the article is to create a nonlinear mathematical model for analysing product lifecycle management. Chaotic nonlinear dynamical processes of product lifecycle are deterministic but have the property that even small uncertainties in initial conditions lead to exponentially growing errors in the management that limit long-term forecasts. The emergence of chaotic behaviour in processes of product lifecycle was explored, focusing on fluctuations. The study employed methods such as systems analysis, correlation analysis, nonlinear dynamics, and the Surrogate model of chaotic Lorenz waterwheel. It was identified that sharp technological innovations as the primary drivers of short-term fluctuations impacting fixed efficiency and effectiveness of product life cycle process development. The resulting nonlinear dynamic model allowed for flexible operation, transitioning between equilibrium, periodic, and chaotic states based on coefficient values for asset growth rates and time constants reflecting product life cycle process dynamics. The research results are valuable for companies seeking to reduce their environmental impact and implement circular economy principles.
