Occupational Health and Safety (OHS) risk management is an effort made to manage the risks of work accidents to minimize the risk of work accidents in a company. The aim and target of OHS risk management is to create an OHS system in the work environment that involves all parties, so as to reduce the number of workplace accidents and create a safe workplace. Therefore, it is necessary to conduct further research on the implementation of the OHS risk management system in the company. In this research, identification and analysis of accident risk have been successfully carried out, as well as making suggestions for risk mitigation in a company in the corrugated carton box sector. In addition, work accident investigations have also been carried out to determine the cause of a work accident and detect latent sources of hazards that were not detected in the risk identification process.

This study investigates the conjugate effects of Darcy parameter and point/line heat source/sink on natural convective, electrically conductive laminar fluid between two infinite vertical plates. The closed form solution to the resulting governing equations is been solved analytically using Laplace transform method, the effect of various parameters embedded in the flow is discussed with aid of line graphs and Tables. During the course of computation, excellent result was found.

PT SILO executed a smelter project on Sebuku Island, South Kalimantan, worth US$ 51.5 million to process 4,725,000 WMT/year of iron laterite ore into 1,701,325 DMT/year of Sponge Ferro Alloy. The Smelter was built to increase the added value of minerals in accordance with UU No. 4/2009 on mineral and coal mining. Financial analysis is carried out to determine the feasibility of the project and its investment capability in providing benefits. Furthermore, fast tracking analysis is carried out to determine the opportunities for accelerating the project completion schedule and its effect on project feasibility. The results showed that the project was financially feasible with an NPV of US$ 86,209,478; IRR of 16.18%; PBP for 12.76 Years; BCR of 1.0520; and BEP at US$ 253.51/ton for the production of 1,617,000 DMT/year. Projects can be fast tracked to accelerate the duration of up to 4 months while maintaining financial feasibility.

Identifying the most influential factors affecting the student’s performance plays a vital role in improvising student’s academic results. The conventional counseling is a time consuming process to understand students’ performance. Machine Learning techniques play a major role in educational institutions to estimate the students, performance leading to better performance in placements. The major objective is to find behavior patterns of students in a timely and accurate manner. We find out the groups of students who need to be counseled in time. The system uses parameters such as attendance status, extra circular activities, grade, technical skills, previous semester results, grasping capability, aptitude grade, interaction with lecturers etc. This also helps faculty members to identify the most influential factors affecting the students’ performance. Analyzing student mental issues for low academic performances is a complex task in the current education sector. The system uses data science technique called as "Association Learning" to find the patterns. The Eclat algorithm is used to find patterns. The proposed system builds as real time application useful to educational institutions to understand students’ behavioral patterns. The system helps faculty to identify the most influential factors affecting the students’ performance. A web browser in the future can be developed and used as an application. More number of parameters can be added to predict the students’ performance.

The wind turbine is a device that is used to harness one of the most abundant renewable energy sources on the planet: wind. It works on the concept of converting wind kinetic energy to electrical energy. Wind turbines are becoming increasingly popular in today's globe since they provide numerous environmental benefits as well as the ability to create enough power for users. A wind turbine's main functioning principle is that it creates electricity when the wind blows. The wind turbine creates more power when the wind velocity is higher. However, regardless of wind speed variations, the goal of this article is to achieve a consistent or controlled output. The goal is to have a controlled output regardless of how quickly the wind blows. This idea is made possible with the help of a converter that is installed within the wind turbine and converts whatever input it receives into a steady, constant, or controlled output. Numerous tests and simulations back up the methods used for this project. The final results that meet the design specifications are compiled and displayed in figures throughout this publication.

In the present era of technology it has been simpler to deal with the disaster both natural and man made. Disaster Management activities rely upon substantial volumes of precise, applicable, on-time geo information that different organization systematically make and maintain. Information Technology is changing each part of human life. Disaster management desires forceful enhancements in its sources to decrease injury and save the lifetime of individuals. The advanced methods of information technology such as web, remote sensing, satellite communication, GIS, etc. can facilitate in coming up with and implementation of disaster management. Web provides a useful platform for disaster mitigation communications. On GIS is basic as effective preparedness, communication and training tool for disaster management on the other hand Remote Sensing as a tool can very effectively contribute towards identification of hazards areas. Communication satellite have become vital for providing emergency communication and timely help into natural disaster monitoring and mitigation mechanisms is critical for hazards reduction. There should be more emphasis on development of new technologies in disaster mitigation. The disaster preparedness and awareness is the only effective method of mitigating the impact of future disaster. In this paper an attempt has been made to highlight the role of information technology in management of natural disaster in Nepal.

People in the rural regions of the developing countries where electricity supply is not available are facing the problems of preserving their food through refrigeration. They need affordable and efficient method of food preservation. Therefore, a solar operated refrigerator was designed, constructed and evaluated. The system consists of three major parts, namely: the mild steel box (0.4 𝑚 × 0.4 𝑚 × 0.5 𝑚), the clay shell and the wooden box (0.5 𝑚 × 0.5 𝑚 × 0.6 𝑚). The mild steel box is enclosed in a clay shell, which is in turn enclosed in a wooden box with four open ducts. The work evaluated convective heat transfer through the ducts and the machine was tested on no load and also by using it to cool 40 kg of water for seven consecutive days over a period of eight hours per day. The results from its performance tests indicated that the system has a cooling process coefficient of performance (COP) of 2.48 and overall coefficient of performance (COP) of 1.64.
