In the teaching of macroeconomics, we should strengthen the curriculum-based ideological and political education. This paper first introduces the necessity of Ideological and political education in macroeconomics; then it analyzes the common problems in curriculum-based ideological and political education of macroeconomics; finally, the paper explores from the concept of curriculum-based ideological and political education, the construction of teachers’ Ideological and political ability and the scientific design the system of curriculum-based ideological and political education in macroeconomics, so as to realize the effect of the coordinated development of the curriculum-based ideological and political education and macroeconomics, so as to help students establish the correct world view, sense of worth, philosophy and cultivate the applied business management talents with a sense of mission and responsibility.

Public health emergencies such as the COVID-19 outbreak has made all industries to reexamine the way the cities have always grown. Urban planning is no exception. Based on the analysis of the development track and phenomenon of Wuhan City, this paper puts forward the planning thinking of the development of China’s big cities. According to the study, it is urgent to study the suitable size, structure and form of big cities. The consistent practice of high-intensity development needs to stop. Urban development should pay more attention to the space that can not directly generate economic benefits.

The paper analyzes the system at higher education in the context of achieving the goals of sustainable development of modern society. From the point of view of a systemic approach, an attempt is made to identify and classify the factors that can measure the contribution of higher education institutions to achieving the Sustainable Development Goals at the regional level. These factors are correlated with the corresponding tasks, as well as possible problems that are posed by the present unstable situation, and hinder sustainable development of the society. The research uses system-wide methods of analysis and synthesis, generalization and analogy. The analysis of the tasks and problems presented in the article allows us to identify and investigate the cause-effect relationships between the factors that determine the achievement of the Sustainable Development Goals and the complexities that accompany this process, and also contributes to the holistic perception of the concept of sustainable development by university staff members and students. The results of the study can be used in event planning within the framework of implementing the strategies drawn up by universities in the context of the sustainable development paradigm.

This paperA total of 62 patients with gallstones and gallbladder polyps were selected from May 2019 to May 2020, who were divided into the observation group (n=31, laparoscopic cholecystectomy) and the control group (n=31, open cholecystectomy) in a 1:1 ratio. The clinical indicators, clinical efficacy, level of pain and complication rate of the two groups were recorded and compared. Results Indicators such as the operation duration (38.64±14.42min), blood loss (30.42±8.21ml), length of stay (4.71±1.82 d), first anal exhaust (21.82±6.65min), drainage volume (72.02±4.21ml), length of incision and the time for the recovery of gastrointestinal functions in the observation group were better than the control group (P<0.05). The clinical efficacy of the observation group (96.77%) was higher than that of the control group (80.65%), with statistical value =4.0260 (P<0.05). The level of pain of the observation group was lower than that of control group (P<0.05), while the complication rate in the observation group (3.22%) was also lower than that of the control group (22.58%) (P<0.05). Laparoscopic cholecystectomy is an effective treatment of gallstones complicated with gallbladder polyps, which can alleviate pain and improve the prognosis, and is thus worthy of promotion.

One of the main sources of water pollution is industry, including food production enterprises. Wastewater of this industry is intensively polluted with easily decomposable organic substances, which can cause great damage to water bodies. Existing wastewater treatment technologies are extremely energy-consuming due to deficiencies in the analysis of the composition of liquid media, which can reveal an excess of maximum permissible concentrations of not more than ten percent of the total amount of normalized pollution. In the present paper, data on the existing wastewater discharge obtained by the laboratory method are presented, and the level of their pollution is estimated. Information about the developed Microbiological Treatment System and its ability to reduce pollutant concentrations is presented: for suspended solids by 17 times, for mass concentration of fats by 17 times, for BOD5 (biochemical oxygen demand) by 45 times, for COD (chemical oxygen demand) by 10 times, in artificially created storage ponds.

The article examines the impact of new economic conditions against the backdrop of the COVID-19 pandemic on the trade enterprises competitiveness using the example of the market of building and finishing materials. The aim of the study is to identify the qualities that a manager, who is able to bring an enterprise out of a crisis state with the least consequences for it, should possess, to develop a model for managing the competitiveness of trade enterprises by forming a set of corrective measures aimed at ensuring the competitiveness of services accompanying the trade in construction and finishing materials. Theoretical studies were carried out using the methods of system analysis and generalization of the existing scientific developments in the field of managing the trade enterprises’ competitiveness [1]. The methods of statistical analysis were used to determine the crisis impact assessment on the competitiveness of trade enterprises and to identify the competitive advantages of the industrial analyzed segment. As a result of the study, the following results were obtained.: - analysis of trends in the retail industry revealed the main problems of trade enterprises in the context of the crisis caused by the spread of a new coronavirus infection; - the use of the fundamental principles of the formation and maintenance of the organization’s competitive advantages made it possible to determine the competitive advantages of trading enterprises in the market of building and finishing materials, using digital technologies in business, allowing to maintain a stable position in industrial market; - relying on a system of long-term competitive advantages, the main activity areas of trade enterprises were identified, which, thanks to corrective solutions, are able to ensure sustainable development in the context of overcoming the crisis caused by the COVID-19 pandemic.
