Enhancing thermal comfort and indoor air quality through energy optimization with neural network

Indoor thermal comfort and air quality are essential for occupant well-being, while simultaneously optimizing energy consumption in buildings. Achieving a balance between these factors presents a significant challenge, as indoor environments are dynamic and energy demands fluctuate. By modifying ventilation rates in response to real-time data, demand-controlled ventilation systems can reduce energy consumption and enhance indoor comfort and air quality. However, optimizing these systems with advanced predictive models remains a complex task. To address this challenge, this publication proposes a Dual-Stream Multi-Dependency Graph Neural Network (DMGNN)-based energy-efficient ventilation management technique that maximizes indoor air quality and thermal comfort. The suggested method seeks to enhance thermal comfort and air quality by maximizing heating, ventilation, and air conditioning (HVAC) operations while reducing energy consumption. Initially data are collected from an Indoor Air Quality Monitoring Dataset. The DMGNN is employed to capture the complex dependencies between environmental factors such as temperature, humidity, and CO2 concentrations, considering both temporal and spatial relationships. Implementing the proposed system and evaluating it through simulations in various building environments demonstrates notable improvements in thermal comfort, indoor air quality, and energy economy. The suggested system’s performance is contrasted with that of other current methods, showing superior energy efficiency and optimization of both indoor air quality and occupant comfort. This study presents an innovative, scalable framework for smart building management, promoting sustainable energy solutions.

Globalization and higher education in india: the changing trends

The latest phase of capitalist expansion is called “globalisation”. That no state is an autarky but enjoys comparative advantage over others with certain resources and that free trade among these states would work for mutual benefit is the essence of it. Consequently, it advocates the minimization of the governmental intervention in economic affairs and encourages free play of market forces to foster economic development. The argument that this rationale is also applicable to higher education is increasingly gaining currency. But this paper attempts to problematise such a proposition and in contrary argues that this may prove inimical to national development. Education and especially higher education is considered to be one of the factors that help state to promoting national development. However, apologists of globalisation call for its commercialization and argue for the “withdrawal of the state” from this realm. This has only resulted in mystifying profound class inequalities within and without state. Higher education in India is not immune to this ideology in the guise of good economics. It is being structured in such a fashion since 1991 that it has been primarily coupled with the process of economic liberalization and privatization. International financial institutions like World Bank, IMF, GATT, GATS, etc are its votaries. Education was acknowledged as one of the key sectors to be traded. As a result, higher education as a “social good” is fast shifting to being a commodity in the market.

Seroprevalence of avian leukosis virus in local chickens in five live bird markets, kaduna metropolis, north-western nigeria

Avian leukosis virus is recognized as an important viral pathogen in the poultry industry, resulting in salient severe economic losses due to reduced production, uneven flock growth rates, reduced growth, and immunosuppression which predispose affected birds to other infections. This study examined the seroprevalence of avian leukosis virus (ALV) in local chickens (LC) in 5 different live bird markets (LBMs) in Kaduna Metropolis. A total of 276 sera were tested for ALV p27 antigen using enzyme-linked immunosorbent assay (ELISA). An overall seroprevalence of 28.3% (78/276) was recorded in the study. At the market level, the seroprevalence of 35% (21/60), 30% (18/60), 32% (16/50), 28.6% (16/56), and 14% (7/50) were recorded for Sabon Tasha, Central market, Railway station, Kawo and Sokoto Road LBMs respectively. With regards to sex, female LC showed a significantly higher prevalence of 30.5% (46/105) compared to male chickens 26.9% (46/171) with no significant difference (P > 0.05) observed. This study established the presence of antigen to ALV in local chickens sold in LBMs. We recommend surveillance and further studies on the isolation, molecular characterization and pathogenicity of ALV in the study area.

Follow-up regularity in eye-care among disease conscious population in delhi-ncr: a gender-based retrospective study

Abstract---In contemporary society, most females are deprived of proper education, healthcare, job opportunities, etc., to uphold family customs, patriarchal dominance, and occasionally negligence towards the feminine gender. According to researchers, gender inequalities in health care, especially in eye care, are evident between accessing the care and getting treatment in developing countries. Therefore, we aim to measure the gender-wise eye-care follow-up regularity in accessing long-term glaucoma consultation among various age groups with a sample size of 564 in Delhi-NCR, India. The age groups (in years) are 15-29 (Group I), 30-44 (Group II), 45-59 (Group III), 60-74 (Group IV), and 75 and above (Group V). Groups I to V show, intragroup males have higher odds of getting regular eyecare by 20% (OR 1.20, 95% CI 0.413 to 3.4871), 2.08% (OR 1.0208, 95% CI 0.4637 to 2.2472), 3.4% (OR 1.034, 95% CI 0.6369 to 1.6787), 8.46% (OR 1.0846, 95% CI 0.6783 to 1.7344), and 45.83% (OR 1.4583, 95% CI 0.4575 to 4.6484) respectively. The probable causes of gender-wise irregularity are lack of seriousness, financial limitations, dependency, loneliness due to widowhood, etc. To make eye-care services equally accessible to everyone, healthcare agencies should first take various progressive policies to overcome gender-wise socio-economic barriers.

The influence of employee empowerment on employee job satisfaction in five-star hotels in jordan

This paper examines the influence of empowerment on job satisfaction in five-star hotels in Jordan. The influence of empowerment on job satisfaction remains a relatively unexplored area. A 52-item questionnaire, measuring empowerment and job satisfaction, was distributed to 332 employees in 12 five-star hotels in Jordan with a 56% response rate. Principal components analysis determined the factor structure and regression analysis determined the influence of empowerment on job satisfaction. The results revealed both structural and psychological empowerment have significant individual influences on job satisfaction, but more significant when structural and psychological empowerment are combined. Most of previous studies were conducted in western economies and little in the Middle East generally and Jordan in particular. This research contributes to the literature by including both dimensions of empowerment where previous scholars used only one.

A study to assess the effectiveness of aerobic training on exercise tolerance and functional independence in patients with multiple sclerosis – a quasi experimental study

Multiple Sclerosis (MS) is a chronic neurological condition characterized by an interruption of action potentials in the brain and spinal cord due to areas of inflammation, demyelination and axonal degeneration. Most people with Multiple Sclerosis (PWMS) complain of physical activity limitations due to fatigue and reduced Exercise Tolerance that leads to reduction in Functional Independence. Till date, there is a limited published evidence of the efficacy of aerobic training on Exercise Tolerance and Functional Independence in individuals with Multiple Sclerosis, although some studies that incorporate aerobic training into rehabilitation programs report positive outcomes with no harmful effects. This was an effort to study the effect of aerobic training on exercise tolerance and functional independence in patients with Multiple Sclerosis. 12 Subjects were selected for the study on the basis of convenient Sampling method. Subjects who were independently mobile with Kurtzke Expanded Disability Status Scale (EDSS) score between 2 and 6.5 and medically stable were included for the study. The parameters of Exercise Tolerance and Functional Independence were assessed with six min walk test distance (6MWTD) and FIMTM+FAM respectively as Pre test measurement. All the subjects were given Aerobic training(AT) with Elliptical trainer and the intensity of the exercise was individualized according to their tolerance with initial stage incline of 0 (no incline) and a resistance of 1 (lowest possible resistance) was fixed. Training was done in a well ventilated training setup and subject was provided with cool water to minimize the effect of heat on activity. Subjects were monitored during the exercise training via heart rate monitor fixed to the machine; heart rate was taken every 3 minutes. The subjects were advised to perform the exercise in their own pace throughout training session for 30 min with breaks as many as they require. Progression of exercise intensity was achieved by increasing the resistance level of the Elliptical machine and/or by increasing the subject's steps per minute (stepping speed was controlled by the subject and not the elliptical machine).To ensure the progress of exercise protocol, the exercise intensity increased every 3 to 4 sessions. Totally 15 sessions were given in 6 weeks period. After 15 session of training Post test measurement for Exercise Tolerance and Functional Independence were taken. The Significance of the Pre test Post test difference were analyzed statistically using student paired “t‟ test . After 6 weeks (15 sessions) of Aerobic training with Elliptical trainer the subjects improved in Exercise Tolerance and level of Functional Independence as compared with the base line conditions. This was indicated by the changes in the Distance covered in 6 MWT and the FIMTM+ FAM score with P value <0.001. In all the subjects who were participated in this study showed greater improvement in the 6 Minute walk test distance and FIMTM+FAM scores. It implies that Aerobic training by Elliptical Trainer is effective for improving Exercise Tolerance and Functional Independence in PWMS.

Development of an online nysc orientation camp information system

The National Youth Service Corps (NYSC) is an organization set up by the Nigerian government to involve the country’s graduate yearly in the development of the country. The one year service period has three weeks orientation period when the corps members are trained in paramilitary training. During this period, the corps members use the manual approach to supply their personal information. The manual method of information system used by the corps members is very tedious, time-consuming, prone to errors, and information modification and retrieval are practically impossible. To solve these problems, an online NYSC orientation camp information system is proposed. The proposed system is analyzed, designed and developed using Entity-Relationship Model (ERM) with an entity-relationship diagram as a defector. The architecture model is implemented using PHP and MySQL programming languages. The results showed that the researchers have developed an interactive online NYSC orientation camp information that can handle updates and modification of data more efficiently and can be accessed anywhere and anytime than the manual methods of information system. The researchers hereby recommended the developed software to the National Youth Services Corps headquarters for efficient database analysis of the corps members’ information system

Effective key management in dynamic wsn

Recently, wireless sensor networks (WSNs) have been deployed for a wide variety of applications, including military sensing and tracking, patient status monitoring, traffic flow monitoring, where sensory devices often move between different locations. Securing data and communications requires suitable encryption key protocols. In this paper, we propose a certificateless-effective key management (CL-EKM) protocol for secure communication in dynamic WSNs characterized by node mobility. The CL-EKM supports efficient key updates when a node leaves or joins a cluster and ensures forward and backward key secrecy. The protocol also supports efficient key revocation for compromised nodes and minimizes the impact of a node compromise on the security of other communication links. A security analysis of our scheme shows that our protocol is effective in defending against various attacks.We implement CL-EKM in Contiki OS and simulate it using Cooja simulator to assess its time, energy, communication, and memory performance.

Pharmacognostic and phytochemical study of the flowers of cordia sebestena l

The present study shows the pharmacognostic and phytochemical studies on the flowers of Cordia sebestena. L. belongs to the family Boraginaceae. C. sebestena L. is found primarily in tropical and subtropical regions of the American, Asian and African continents. Though it is an essential plant, no pharmacognostic work has been found on its parts, such as flowers. Various organoleptic characters were recorded by macroscopic study. A microscopic study of the flowers was also conducted, which shows the presence of fibres, calcium oxalate crystals and multiple types of trichomes, along with fluorescence analysis. The present study also deals with the Fourier transform infrared spectroscopic analysis of C. sebestena L. FT-IR spectra revealed the presence of C-H, C=C, C-N, C-O and aromatic groups. The chemical composition of the hexane extract of the flowers of C. sebestena L. was detected through GC-MS, and the spectrum achieved through GC-MS was correlated with the database of the National Institute of Standards and Technology (NIST) which comprise more than 62000 outlines of the mass spectrum. GC-MS analysis of n-hexane extract showed the existence of Retinoic acid, lupeol, β-sitosterol, stigmasterol, and hexadecanoic acid, along with fatty acids, esters, alkaloids and alcohols. These pharmacognostic and phytochemical studies can be valuable in providing reliable proof of the quality of the plant, which can benefit health professionals and herbal medicine manufacturers.

An epidural collection due to streptococci agalactiae

An Indonesian lady aged 52 years old presented to the emergency department with a 2-week history of lower backache. One-week later, she developed urine retention followed by bilateral lower limb weakness, and since then, she has been unable to walk. Her medical history, family history, and social history were unremarkable. She has no previous history of trauma or similar presented symptoms. Clinical examination showed spastic paraparesis with hyperreflexia. Blood chemistry showed HbA1c of 11.6, and the fasting blood glucose was 14.2 mmol/l. Contrast-enhanced magnetic resonance imaging (MRI) showed an epidural collection extending from T9 to S1 and occupying predominantly the anterior epidural space, with extension toward the posterior epidural space in the lumbosacral region (Fig. 1a). The provisional diagnosis was Pott’s disease, and lumbar (L) hemilaminectomy at L2 was done to drain the epidural collection. Mycobacterium tuberculosis was not detected by acid-fast bacilli or polymerase chain reaction testing of the specimen. However, the drained epdural collection was positive for penicillin-susceptible streptococci Agalactiae. Blood cultures were negative, and transesophageal echocardiography did not show any vegetations. The patient received intravenous ampicillin for 2 weeks, then switched to oral antibiotics for another 6 weeks, and was referred to the rehabilitation center, where she improved and was discharged after 8 weeks with a walker. A repeat MRI (Fig. 1b) showed a complete resolution of the previously described epidural collection.

Knowledge, attitudes, and practices toward covid-19 among yemeni health care workers during the covid-19 pandemic: a single-center survey in al-thawra hospital, ibb governorate, yemen

Background and Objective: Health care workers (HCWs) are at the highest risk of contracting COVID-19, so their knowledge about the disease and their preventive attitude and practice toward COVID-19 are of concern. The present study aimed to assess the knowledge, attitudes, and practices of HCWs toward COVID-19 in Al-Thawra Hospital, Ibb Governorate, Yemen. Materials and Methods: We conducted a cross-sectional survey among HCWs in Al-Thawra Hospital, Ibb, Yemen, from January 1 to March 31, 2022. Results: Of the 80 participants, 50 (62.5%) were males and 30 (37.5%) were females with a mean age of 29.33±7.86 years. About 51.2% of respondents were aware that sneezing is a recognized symptom of COVID-19, while most were unaware of the extrarespiratory symptoms of the disease, such as diarrhea and confusion. About 28.7% of respondents believed that eating or contacting wild animals would result in infection by the COVID-19 virus, with the majority (71.3%) agreeing that wearing a well-fitting face mask effectively prevents COVID-19 infection. Approximately 48 respondents (60.0%) believed that washing hands could prevent contracting COVID-19, and only 31 (38.7%) agreed that if a patient shows signs and symptoms of COVID-19, they can confidently participate in that patient’s treatment. In response to avoid COVID-19, about 23 respondents (28.7%) had always gone to crowded places, and 35 (43.6%) had always worn face masks at every contact with patients, while only 14 (17.5%) of participants refrained from shaking hands and 37 (46.3%) always washed their hands before and after handling each patient. Conclusion: This study showed that most respondents have poor knowledge regarding the clinical picture of COVID-19 and its mode of transmission as most of them failed to detect an extrapulmonary manifestation of COVID-19 and were unaware of the possibility of transmission of the disease from wildlife. In addition, the attitude and preventive practice of the respondents were unsatisfactory in containing the transmission of the disease.
