Energy-Efficient Buildings, a step towards Sustainability in Pakistan
109-124Views:247With every passing year, energy consumption in the world is increasing drastically. Most of the energy comes from fossil fuels which are also depleting in a fast manner. Buildings consume a significant amount of energy all over the world and the demand for energy is also increasing unremittingly in buildings. Developed countries are taking profound measures in order to make buildings energy efficient and sustainable by achieving nearly zero energy stage. Pakistan is facing a serious energy crisis from the past few decades. The building sector in Pakistan deserves special attention in this regard since the energy consumption in buildings in Pakistan is feverishly high. Many types of research have been carried out in Pakistan by the United Nations and Energy Department of Pakistan in order to devise applicable methods that not only provide thermal comfort to the occupants but also make a building energy efficient. Renewable energy also plays an important role in compensating building energy demands. It is easy to achieve nearly zero energy state in a good energy efficient building if it is coupled with renewable energy sources then it will make it self-sufficient in energy demand. A survey is also carried out to determine the thermal comfort of the occupants in different types of areas. Also, solar energy analysis is also taken into account to highlight the solar power potential in Pakistan. Several recommendations have also been suggested to implement energy efficiency measures in Pakistan.

Investigation of SCOR Model in Connection with Performance and Warehouses
227-239Views:145Business leaders can use several strategic tools to improve the organization, depending on what they consider to be important. The Supply Chain Operational Reference Model (SCOR) is one of these. Its importance is to link business processes, performance metrics, best practices, and technology together and to create a unified structure. It promotes communication between the stakeholders of the supply chain and improves supply chain management and the efficiency of the related supply chain improvement activities. The aim of this study is to find out how the SCOR model appears in the international literature related to warehousing and performance. What methods and tools do authors use to investigate their research questions and hypotheses? Description statistics and category selection were used to present the results of the study. The number of SCOR model researches related to warehouse performance measurments are very rare, it is rather used to describe different processes. In the future, it would be worthwhile to extend the SCOR model analyzes to further fields, especially to warehouse performance measurements.

The green methanol - playing a role in sustainable energy management
249-258Views:150Global energy demand is constantly increasing, so the energy sources we use, and the efficiency of energy use are of paramount importance for the future of humanity. Methanol can play a key role in the sustainable use of natural resources, in the efficient and smooth transition from a fossil oil-based energy system as well as in reducing greenhouse gas emissions. Long-term thinking will result in an increase in the use of renewable energy sources, which will favour the spread of green methanol technology and thus the use of a carbon-neutral fuel. The raw materials for the production of green methanol may include municipal solid waste, agricultural waste, renewable hydrogen and carbon dioxide and the methanol has many uses, both as fuel and chemical feedstock. It also provides an opportunity to chemically store excess renewable energy from intermittent sources, thereby reducing dependence on fossil fuels. The price of electricity used for electrolysis is the main determinant of the economical production of green methanol, so the reduction of the cost of solar and wind energy greatly contributes to the competitiveness of carbon-based production.

Generational Transfer Among Family Businesses on the Fields of Reputation and Organizational Culture – Research Plan
102-108Views:114Aim: The aim of this paper is to generally introduce the topic, themes and relevance of the research on which my PhD thesis will be based. The research will focus on change of generations among Hungarian family businesses and deals with changes of leadership, organizational culture and core values, related to the management/owner succession. The research needs to apply knowledge from four disciplines ‒ PR, organizational culture, economic (family businesses) and leadership ‒ so it is multidisciplinary in nature. Following a current step of the research-process will be presented.
Methodology: The Family Business Barometer results were applied for gaining information about the plans related to the future, generations, and so on of European Family Businesses. Then three Hungarian family businesses were interviewed in the frame of a panel-discussion organized by the Commercial and Industry Chamber in Győr-MosonSopron County. These three family businesses were the Borsodi Műhely, the Biotextima and the Leier.
Findings: All in all between 2013 and 2016 most of the family businesses seemed to be confident about the future. In this aspect just a few family businesses were neutral in this time period. Unfortunately, there were family businesses who had a negative attitude for the future. The deliberate and detailed planning of the handover, the selection of a determined date for handover, the determination of the older generation to really do not interfere in affairs, the cohesive role of the family, family activities, the support from the family could lead to the effective change of generations.

Maintenance Strategies and Life Cycle Costs of Renewable Energy Systems
106-116Views:121Life cycle costs are important factors in decisions on renewable energy investments. Since maintenance costs generally constitute a high portion of the life cycle costs, the maintenance strategy applied in a project can affect the bottom line significantly. The effective maintenance tools used in the production industry (e.g., diagnostics, condition monitoring, data management, integrated information systems, machine learning, and automated decision making) can be involved in planning and maintenance of renewable energy systems to gain the benefits of these approaches. In this paper the effects of maintenance strategies on life cycle costs are investigated and the benefits of up-to-date condition monitoring techniques are presented through case studies.

Justification for the Olympic Reform Package Based on Good Practice
Views:236The Olympic Games have always been the pinnacle of sport and achievement. The modern Olympics are held every four years, and the venue is chosen from among the cities that apply. In my research, I wanted to find out the reasons for the decline in the popularity of the Games. To answer this question, I looked at 2 successful Olympics (2000 Sydney, 2012 London) in the hope of identifying success factors that could be adapted to other host countries. I conducted secondary research, reviewed related international and national research, and the available economic data. During the document analysis, I found that the expected costs of organising the Olympic have increased significantly over the last two to three decades, and under-planning is a common feature. As a result of the research, I have found that the most important pillars of successful organisation are a proper organising committee, comprehensive opportunity and risk analysis, accurate planning, sustainability in planning, continuous cost control, private sector support, and the work of volunteers.

Studies on Consumer Motivation Among Users Of Fitness Services
442-453Views:280The rate of inactivity experienced world-wide is the cause of numerous health problems. The sedentary lifestyle of the population represents a great burden to a nation’s economy. The health indicators of Hungary are below the European average, not only those concerning physical activity, but also with respect to smoking, nutrition, and alcohol consumption [1]. In 2013, only 38% of the Hungarian population exercised regularly, while 62% rarely or never [2]. The diseases associated with inactivity represent a higher burden to the economy than the costs of raising the level of activity would be [3]. Based on previous studies, the motivating factors for leisure athletes in Hungary are the preservation of health, to increase physical strength, relaxation, recreation, the love of exercising, and stress management [4; 5]. The sports facilities available to a wide range of people, the fitness clubs offer the possibility to join regular sports activities, which is why it is necessary to examine the motivation behind the participation of athletes taking part in the trainings provided by fitness facilities. Many previous studies examined the goals of athletes and the motivational factors behind exercising, and came to the conclusion that trainings held in fitness rooms and at home are related to intrinsic motivational factors, while taking part in other sports activities are related to intrinsic motivational factors [6; 7]. The focus of my study are leisure athletes using the services provided by fitness clubs (753 people), of whom I evaluated the motivational factors behind taking part in trainings. The results show that the motivational factors driving consumers of fitness services show a ranking that is identical to those of other leisure athletes, with most of them taking part in fitness trainings in order to preserve their health, to improve physical strength, and for recreational purposes, while the improvement of physical appearance also plays an important role.
