In this paper, we have constructed a five-dimensional Bianchi type I cosmological model with strange quark matter in the context of Saez-Ballester theory of gravity. We have discussed a five-dimensional cosmological model by using the special rule of variation for the Hubble parameter in the shape of H = Da-1 and the equation of state for strange quark matter. Two different models for n ≠ 0 and n = 0 have been discussed. Also, the accelerated expansion of the Universe has been discussed by using various physical parameters and its graphical representation.

This survey is to summarize some aspect of the IX International Scientific and Practical Conference “Bi-, poly-, translingualism and language education” (30.11. - 02.12.2023, Peoples’ Friendship University of Russia named after Patrice Lumumba, Moscow) that deals the name of Gennady P. Melnikov - an outstanding scientist, philosopher, systemologist, and linguist. The review indicates the specifics of the conference, presents some essence of systemology, and describes the content of some reports.

In the recent years, the devices in Internet of Things (IoT) are growing exponentially due to the emergence of many sophisticated applications. This tremendous growth leads to serious security challenges and the devices of Wireless Sensor Networks should be protected from various attacks. IoT can be configured dynamically without fixed infrastructure and the devices are communicated with one another in an Ad-hoc manner. The work presents the classification of various DDoS attacks in the IoT environment and provides a solution for replay attack. All variations of DDoS attacks are modeled using UML based activity modeling. This clearly understands the behavior of each version of attacks and their performance in the environment. The modeling also helps to construct a solution to prevent this attack from its execution. The work also proposed a trust based protocol for replay attacks which allows the attack inside the network and blocks it after identifying the attack based on its specific behavior. The network performance is improved after implementing this proposed protocol inside the network with help of simulation under realistic conditions. The performance metrics considered in the work are energy, packet loss, computational time and throughput. The paper compares the performance with the state-of-the-art schemes such as Efficient Distributed Deterministic Key and Hashbased Message Authentication Code. The experimental analysis proved that the proposed scheme outperforms the other state-of-the-works in terms of computational cost, throughput, and delay.

Relevance. Nursing process is a scientific method of organizing and providing nursing care. Due to imbalance of nurse patient ratio, application of nursing process in actual clinical setting is very limited which reduces the quality nursing care. Despite the importance of application of nursing process, there is no standard nursing process protocol available in the hospital where study was carried out. The governments set a standard nurse patient ratio in Nepal, UK and USA is 1:10, 1:8, and 1:5 respectively. However, global statistic has been revealed due to improper nurse patient ratio which cannot implement the nursing process for patient caring which are being for leading cause of mortality of patient in hospitals. Aim of the study. The study was conducted to assess the application of the nursing process among nurses working in teaching hospital. Additionally, this study explores the association between status of application of nursing process and selected variables. Materials and Methods. Based on a descriptive cross-sectional study design. A simple random sampling technique was applied for nurses working in tertiary hospital of Chitwan, Nepal. The data was collected using structured questionnaire among 182 nurses. The statistical analysis tool chi-square was used to find out the association and logistic bivariate to find out the odds ratio. Results and Discussion. The result indicates that only 23,1 % of nurses have moderate level of application of nursing process. Majority of nurses did not follow standard ways of nursing process. This study also explored the infl ncing variable for barriers related to nurses and profession. Age (p=0.001), professional qualification (p=0.001) and learning approach (p=0.022) were the significant influencing variable for barriers related to nurses whereas practical skill (p= 0.001), cooperation among nurses (p=0.008) and diffi in diagnosis characteristic (p=0.010) were the barrier related to profession. Conclusion. It was concluded that the majority of nurses working in teaching hospital of Nepal did not follow the standard ways of nursing process so that barriers for the application of nursing process are identifi The overall ratio of nurses to patients in the teaching hospital is 1:16, that is in the lower range than the standards set by the government. Therefore, special attention must be paid to adherence to a standardized nursing process protocol for quality medical care.

Relevance . Oxygen therapy is commonly used in the emergency and critical cases which is the first line treatment in many critical conditions. Oxygen therapy is a medical treatment prescribed mainly for hypoxic patients, which provides oxygen at higher concentrations than that found in atmosphere (21%). Oxygen administering depends on the needs of the patients conditions and in some cases medical treatment. The present study aims to assess the level of awareness on oxygen therapy among nurses and examine the association between level of knowledge, attitude and selected socio-demographic variables. Materials and Methods . A quantitative descriptive cross-sectional study design was used. A non-probability purposive sampling technique was used to select 125 samples. The data were collected for 6 weeks using a semi-structured self-administered questionnaire. Descriptive statistics (frequency, percentage, mean, standard deviation) was used for quantitative data analysis and inferential statistics (chi-square) were used to find out the association between level of knowledge, attitude and selected socio-demographic characteristics of the respondents. Results and Discussion . The study revealed that 74.4% of the nurses had unsatisfactory level of knowledge, 20% had average knowledge and 5.6% had satisfactory level of knowledge regarding oxygen therapy. A significant association was found between the knowledge level and age, educational status and experience of the respondents (p=0.001, 0.000, 0.016). Conclusion . The study concluded that the level of knowledge among nurses regarding oxygen therapy has lower than expected and is unsatisfactory. The results of the study can provide a framework for the healthcare policymakers to develop and implement educational programs on oxygen therapy for nurses in hospital setting.
