Opportunities and Challenges of Toy Manufacturing Sector in India

This article studies the opportunities and challenges that persist for the Toy Manufacturing sector in India. India is named for its traditional toy a year back history of 5000 years. The industry gives more employment opportunities and provides more revenue to the people who depend on it. But due to the change in liking of traditional toys, patterns and innovation of Chinese toys create a great deal of trouble to the Indian manufacturers. The study is essential in estimating the opportunities and challenges available in the toy manufacturing sectors in India. The study adopts the literature survey approach, mainly from various agencies' reports and news from the websites. The at manirbar mantra, Covid 19 influence, Global scenarios link shows significant opportunities for toy manufacturing sectors. Challenges are found to be in the availability of foreign toys, increased import duty on raw material and capital goods, and introduction of quality standards in Toy Production.

Maximization of Tensile Strength of Aluminum 6061 Alloy T6 Grade Friction Welded Joints by Using the Desirability Function

Various joining techniques are consistently used in fabrications and maintenance applications of numerous parts in manufacturing industries. Typically, the friction welding technique acquired attention in joining of aluminum and its different alloys for very general structural usages in small to medium to large-scale manufacturing sectors. This is an experimental attempt to weld aluminum 6061 alloy T6 grade of 3mm thickness metal sheets. The hexagonal-shaped steel pin of grade H13 is used. The experiment is performed by using the Taguchi L9 approach, and nine welded specimens are prepared. The chosen factors are rotating speed of the tool, tilting angle, and feed. After the welding, the tensile testing is followed for the measurement of strength of the welded samples. The analysis suggested that the chosen working limits of feed and rotational speed is significant and having impacts on weld strength. The maximum strength is obtained as 212MPa when the ranges of above said factors are 560RPM, 0degree, and 20mm/min.

Spirituality and the Negotiating Ability of Leaders

Since the early 1980s researchers have shown increased interest in integrating spirituality and leadership. Spirituality has emerged as a discrete construct underlying the essence of effective leadership, and the negotiating ability has been regarded as one of its core descriptors. The study, on which the present chapter is based, attempts to ascertain the relationship between spirituality and leaders' negotiating ability. The sample for this study consisted of 450 leaders and 904 subordinates working across different service and manufacturing sectors in India. With the help of a mixed-method research design, data was gathered employing several tools. Leaders' spirituality has been measured through MacDonald's spirituality inventory and their negotiating ability through Rai's model. The study reveals that leaders' negotiating ability is a function of spirituality, and a proper understanding of spirituality improves negotiating abilities of leaders. It offers workable suggestions and outlines the implications of the results for policy and practice.

Adoption of Virtual Reality in Construction Projects

In recent years, virtual reality has emerged in various fields such as manufacturing sectors, construction sectors etc. Virtual reality technology has a wide variety of applications in various fields. Several applications of VR in construction sector are design review and support, construction support, operations and management, safety training, stakeholder management. Recent researches had shown that VR can also be used widely in decision making process. Despite the various applications of VR in construction sectors, the adoption level of the VR technology is comparatively very low. This study aims to identify the factors that are preventing the adoption of virtual reality in construction projects. The factors are identified through a wide review of literature survey and analysed by means of questionnaire survey with statistical methods. The factors are ranked through the analysis and the most affecting factors are found out. The findings of this study show that requirements of specialized high processing equipment, high investment in VR, lack of awareness about the technology, lack of client’s interest, limited finance of the organizations, existence of champions using VR are the most preventing factors for the adoption of VR in construction projects. To mitigate these issues, several possible mitigation measures has been suggested in this study.
