Authors:Syed Zeeshan Haider, Chen Qinghua Pages: 1 - 18 Abstract: With the continuous development of the logistics industry, forklift trucks, as essential handling equipment, play an important role. In recent years, the sales volume of forklifts has increased dramatically, and the manufacturers of forklifts have developed more rapidly. Besides having high energy sales, modern forklifts also have to consider safety. The forklift seat is the most contact between the driver and the truck. Road factors cause the vibration of the forklift truck, and the operation process is reduced by the seat, which improves the safety and driving conditions for the driver. Based on ergonomics, this paper analyzes the working environment of the forklift seat, puts forward the design goal of the seat, and extracts the design method to improve the safety and comfort of the forklift seat based on ergonomics theory: the seat comfort position, shape, size and other comprehensive design research. According to the data on adult human body size provided by GBl0000-88 and the ergonomics principle of seat design, the relationship between seat parameters and human body size data is studied. A forklift seat size data suitable for the The seat's comfort (H point) position range is calculated using Matlab software. Based on the ergonomics design module of CATIA, this paper evaluates the comfort of the forklift seat, and the results show that each part meets the comfort requirements of the forklift seat. ADAMS/View simplifies the seat frame structure, the shock absorber model is established, the drive is created using the SWEEP function, and the virtual prototype model is established. The related transfer characteristic curves are obtained according to the dynamic simulation of the seat frame with different load weights. The results show that the increase of spring stiffness shows a linear increase. It is shown that increasing the damping coefficient of the spring can effectively enhance vibration reduction. This conclusion is also verified by driving the vibration test of the forklift seat. PubDate: 2023-02-23 DOI: 10.9734/ajarr/2023/v17i3469 Issue No:Vol. 17, No. 3 (2023)

Study Design: The study used a case study research design. Methodology: Three research instruments, namely; documents, interview and semi-structured open-ended questionnaires was used for the study. Twelve (12) teachers were sampled from a teacher population of forty-eight (48) mathematics teachers from nine (9) government assisted Senior High Schools in the Keta Municipality to respond to the questionnaire, while a Deputy Director of Education was interviewed to gather qualitative data for analysis. Results: This research study identified that professional development had positive impacts on the Pedagogical Content Knowledge of mathematics teachers. These findings imply that, professional development for teachers is important to ensure effective teaching for improved performance of students in mathematics. Conclusions: Teachers were of the view that they should be included in the planning process of the professional development programmes, realistic duration for the programmes, they also suggested teacher motivation for participation, called for consistency in the organization of the programmes, follow-up programmes and also provision of adequate learning materials.

Authors:V. Kakulapati, A. Jayanthiladevi Pages: 29 - 35 Abstract: In the present day situation, decreasing COVID-19 risk elements also can moreover need to probably check the abilities to provide and test AI-primarily based total models for COVID-19 severity prediction. This work aimed to select the maximum affecting abilities of COVID-19 chance elements and enhance the functionality of the AI method for COVID-19 chance elements primarily based totally on the chosen abilities. In this study, proposed a method for determining whether or not a patient has a chance of contracting COVID-19 by making use of an AI characteristic that becomes incorporated into the feature-fitting learning process (FfitL-CoV19), while also taking a number of symptoms into consideration. Textual data has been divided into traditional and ensemble system learning algorithms as part of the AI characteristic that is becoming a part of the learning process that is being offered. Feature engineering has become completed the use of the AI technique and functions skills have been provided to conventional and ensemble system learning classifiers. The hybrid approach that was made is a big step up from what had been done before, and it can be very effective in all situations. Using the method shown, a structural model could be made that shows how COV-19 infections can spread and cause more infections.

The purpose of the study was to determine the factors favoring non-accessibility to primary health care in the Yelenge health area and to propose strategies to improve access to primary health care in this health area in particular and in the Yakusu health zone in general. Methods: A descriptive cross-sectional study conducted in the Yelenge health area during the period June 1 to December 31, 2022, which involved 500 inhabitants of the Yelenge health area in the Yakusu Health Zone. Results: It was found that 280(56.0%) of the study subjects indicated low socio-economic level (lack of financial means), the influence of traditional medicine 100(20.0%), the absence of qualified personnel 70(14.0%) and the absence of essential health care materials and medicines 50(10.0%) as the main factors favoring non-accessibility to primary health care. Conclusion: Access to primary health care for the inhabitants of the Yelenge health area is a serious problem that requires the unfailing involvement of the health authorities in order to reduce the mortality and morbidity rate in this part of the country.

Being such entails a state of being unconcerned with finances since a person believes that he or she has got it covered. Mindful of the adverse effects of COVID-19 pandemic on the financial well-being of employees in practically every business, the said crisis has increased stress in a wide range of situations for teachers knowing that they nevertheless paid less than comparable professionals. The purpose of this study was to determine how teachers perceive their financial freedom in the new normal. To achieve, the researchers employed a qualitative-phenomenological approach to explore the reality in an in-depth manner. The use of a qualitative research design, on the one hand, allowed the researchers to properly consider the narratives which came from the personal lives of the chosen participants for this study. On the other hand, phenomenological approach in qualitative research was utilized for the exploration of the phenomenon. Through the utilization of this approach, the researcher was able to fully grasp the realities faced by the participants of this study. Twenty participants were chosen purposively to guarantee that they would provide the most substantial data. In-depth interviews were conducted and the participants’ responses were transcribed. Thematic analysis was employed to analyze the bulk of data and organize theme to bring to light the most emergent theme. Results showed that the teachers had dissimilar financial situations since some of them said that they were financially challenged, some became more financially concerned, while others said that they were financially stable during the pandemic. Also, the pandemic setting made teachers to realize the need to observe financial judiciousness through the realization of the essentiality of financial sensibility and the necessity of financial austerity. Further, the teachers were able to gain significant insights such as the need to prioritize financial stability through well-managed finances, financial control, and financial integrity.
