The construction and development of the Blue Economic Zone on the Shandong Peninsula in China was elevated to a national strategy in 2011, and it has achieved year-on-year economic growth, driving the economic development of Shandong Province. However, it has also generated problems, such as a fragile ecological environment, unbalanced regional development, and prominent human–land conflicts. Therefore, on the basis of the idea of green sustainable development, this paper measures the ecological welfare performance of seven prefecture-level cities in the Blue Economic Zone of Shandong Peninsula from 2011 to 2020 using an entropy-weighted model together with the TOPSIS method. It then analyzes their spatial distribution characteristics using the natural breaks method. Our findings show that the overall ecological welfare performance level in the Shandong Peninsula BEZ shows a stable upward trend, and that the ecological welfare performance of each city is similar to that of the divided region. The ecological welfare performance levels of Weifang, Rizhao, and Binzhou are relatively low. Dongying, Weihai, Qingdao, and Yantai form a cluster of cities with high ecological welfare performance. Therefore, for the advancement of the Shandong Peninsula BEZ, the government should the government should reasonably deploy the industrial structure; actively implement industrial transformation; strengthen the synergistic development among cities to achieve complementary advantages, coordinating the growth of rural and urban areas; and improve the social security system to achieve high-quality sustainable development in the Shandong Peninsula BEZ.

The paper describes a problem of project maturity of Polish and foreign construction companies. They were analyzed by their ability to execute construction investment projects. Survey results refer to issues related to the organizational culture and challenges connected with an improvement of the processes of project management for construction. Generation Y employees, their value, and their role at work were discussed in particular. It was underlined that modern managers should be able to profit from skills of Generation Y and to employ and retain the best of them in order to build a competitive advantage of the company. It was revealed that a success of the company is connected with an increasing level of project maturity as a condition for a successful project management.

The growing demand for electricity forces the humanity to find the most economical methods of its production. Functioning without electricity in today's world deprives human from the possibility of a free existence, and even completely prevents it because of the technicisation of society. Growing awareness of acquiring "clean" environmentally-friendly energy from renewable sources contributes to the successive development of this sector of the economy. The purpose of the article was to analyse the risk of construction costs for small hydroelectric power plants along with an indication of the location and needs of a small hydroelectric power plant in Poland. The subject of the study was a small hydroelectric power plant producing electricity, using a turbine to convert the kinetic energy of water into mechanical energy. Aiming at illustrating the benefits of the discussed investment based on the estimation of construction costs and, as a result, financial results, a specific case of a small hydroelectric power plant located in the region of Kujawsko-Pomorskie [Kuyavian-Pomeranian Viovodeship] in central Poland was analysed. The intended research objective was achieved using industry literature, magazines as well as technical knowledge of persons holding building qualifications (including hydro-technical construction) and materials made available by two Bydgoszcz companies specializing in the implementation of small hydroelectric power plants. The COMAR- Jarek Górecki® algorithm, which operates in the industry as the author's concept of calculating the variation of financial outlays incurred for the implementation of investment and construction projects, was used to analyse the risk of costs of a construction project.

Construction is one of the most energy-intensive sectors in the world. To scale down the energy demand of the building sector, some changes must be made. Formal exemplifications of this need can be seen in recent changes in the law in different countries. The energy identity/performance certificate contains requirements about buildings' energy consumption in Turkey, and the Energy Performance Regulation in Buildings is mandatory from 01.01.2020. Moreover, it aimed to measure the level of awareness of individuals in saving energy. Face-to-face surveys were conducted with the use of a questionnaire with individuals residing in Adana's pilot region on the awareness of similar issues such as green buildings and energy efficiency, especially energy identity/performance certificate. The survey results were prepared in Microsoft Excel, and the reliability of the survey questions was measured with the help of the SPSS (Statistical Package for the Social Sciences) program. The analysis of the data was obtained from WEKA (Waikato Environment for Knowledge Analysis). Association rule extraction, which is one of the data mining methods, was used in the analysis. Based on the findings, it was seen that most of the individuals did not have enough information about the topics in the survey. [ABSTRACT FROM AUTHOR]

The article describes chosen problems related to project management. A complexity of these problems involves necessity to search for IT tools supporting the work of project managers. Software tools allowing for analysis of project resources are example of such solutions. The article describes various project management software tools currently available on the market. It also contains opinions on applicability of such programs according to certain criteria selected for various project types. [ABSTRACT FROM AUTHOR]

The article describes a problem of the risk in project management. It presents various project delivery systems in construction industry. It gives also a list of risk factors corresponding to selected project delivery systems. A correlation between risk of the tasks and risk of the project was underlined. It was pointed out that risk in terms of basic attributes of the project, such as: time, cost and quality decreases along with an increasing number of the tasks being assigned to one contractor.
