Grade 5 students were involved in the study of Task Based instruction through activities in order that they could use language in the real life situation. For data collection, it was gathered through different tools like classroom observations, semi structured interviews, audio recording, oral pre tests and oral post tests. The semi structured interviews were conducted from the participants before intervention in order to know about their perceptions of their English language class, teachings of speaking skills including challenges and about Task Based instruction. Oral pre tests and oral post tests were also conducted from the focused group participants in order to know about the effectiveness of Task Based instruction whether it had improved the OCSs among the students. Data that was gathered was analyzed qualitatively to explore the effectiveness of Task based instruction approach in enhancing OCSs among grade 5 students. According to the research findings the study revealed positive impacts of Task Based instruction approach in enhancing OCSs focusing on fluency and accuracy and the researcher expected that the study would definitely help other researchers, English language teachers and students understand Task based instruction approach. In conclusion, the study may inspire the English language teachers to make class learner centered by making task based activities so that the learners can be able to use the language and to enhance their OCSs

The trend seems to continue as long as the robotics technology meets diverse and challenging needs of the food producers. Rapid developments in digital computers and control systems technologies have significant impact in robotics like any other engineering fields. By utilizing new hardware and software tools, design of these complex systems that need strong integration of distinct disciplines is no longer difficult compared to the past. Therefore, the purpose of this paper is to design and implement a microcontroller based on reliable and high performance robotic system for food / biscuit manufacturing line. We propose a design of a vehicle. The robot is capable of picking unbaked biscuits tray and places them into furnace and then after baking it picks the biscuits tray from the furnace. A special gripper is designed to pick and place the biscuits tray with flexibility.

Monte Carlo simulations with 1000 independent replications are conducted to generate conditional variances with standard normal, Students-t and Skewed-t distributions. It was found that though the Li-Mak test has higher empirical size than the nominal size of 5% but can be considered a better alternative to the Ljung-Box test in case of asymmetric errors. The empirical power of the Li-Mak test was also found slightly better for asymmetric heavy-tailed data.

To secure an end-product that is as high a quality as possible, thus satisfying the customers, Quality Assurance is essential. A software application released with several so-called "bugs" and other flaws is obviously a product which has passed through a poor Quality Assurance process. Thus, it is important to have a proper, systematic program to follow during the developments, which ascertain the final quality of the product. Too much QA however, can lead to developers focusing too much on analyzing and documenting every part of the development, ending up with an overload of documentation. This would slow down the development progress, and in the worst case, kill of the project. There are two main aspects of this paper; first problems of "inappropriate amount of Software Quality Assurance" and second is "how we can balance between creativity and quality"? However, we will briefly visit other industries to shed light on the importance of QA as a whole.

Unavailability of data and its proper management are the pressing problems of rural planning agencies over the years, which are responsible for the delay execution of policy proposals in developing countries to some extend. Hence, CBDS was developed to manage rural data regarding various development sectors, but mostly physical and socioeconomic. Data can be easily retrieved with the help of this system, which can help in the formulation of relevant policies. Transportation policies can be formulated on time with the help of CBDS focusing accessibility problems. Transport accessibility can ease out the difficulties of rural-regional population in accessing amenities and credential services.

The goal of this research is to determine public sector education institution's shortage and analyze them according to the national standards. Data were collected from the concerned authorities and significant official documents. After words, the data were authenticated using different statistical tests which were performed with SPSS. The education institution's backlog was calculated by referring the national standards up to the year 2035. The subregional education maps were also produced which show the current and projected Taluka wise education institution's demand. This research could be helpful for policy planners in formulating education policies, especially in rural regions of the developing countries. This research could play a magnificent role in upgrading education standards within the context of poor subregions.

IoT based healthcare systems play a significant role in ICT and have contribution in growth of medical information systems, which are underpinning of recent medical and economic development strategies. However, to take advantages of IoT, it is essential that medical enterprises and community should trust the IoT systems in terms of performance, security, privacy, reliability and return-oninvestment, which are open challenges of current IoT systems. For heightening of healthcare system; tracking, tracing and monitoring of patients and medical objects are more essential. But due to the inadequate healthcare situation, medical environment, medical technologies and the unique requirements of some healthcare applications, the obtainable tools cannot meet them accurately. The tracking, tracing and monitoring of patients and healthcare actors activities in healthcare system are challenging research directions for IoT researchers. State-of-theart IoT based healthcare system should be developed which ensure the safety of patients and other healthcare activities. With this manuscript, we elaborate the essential role of IoT in healthcare systems; immense prospects of Internet of things in healthcare systems; extensive aspect of the use of IoT is dissimilar among different healthcare components and finally the participation of IoT between the useful research and present realistic applications. IoT and few other modern technologies are still in underpinning stage; mainly in the healthcare system.

Hillside development often contains environmental constraints because of hilly topography. Planners and decision makers have a limited opportunity to implement innovative approaches in land-use planning decision making process. This paper discusses on a possible MCDA (Multi Criteria Decision Analysis) method of land suitability analysis for sustainable hillside development. A hierarchical structure model is developed for the land suitability analysis. Land-use planners can get benefit from MCDA techniques for hillside development projects and various kinds of land-use planning problems. Criteria are prioritized by the experts and a number of sub-criteria are set in order to select the best alternatives for sustainable hillside development by using AHP method. Various techniques and modules are available that can check uncertainty of a computed final decision by experts. CR (Consist...
