Practical Research on Business Data Analysis Course Based on Project Curriculum Reform

The teaching of professional courses in domestic colleges and universities mostly focuses on the teaching of theoretical knowledge, and there is still a lot of room to improve students' practical ability, ability to analyze and solve practical problems and innovation ability. Most of the professional courses in many colleges and universities are cases formed by manual sorting or over processing, which are quite different from the actual project situation. Aiming at the problem that the traditional professional course teaching is out of touch with the practical application ability of enterprises, this paper explores the curriculum reform method of immersing real projects in the teaching process, which is oriented to the needs of enterprises. This study analyzes the teaching background of data analysis courses, describes the content, process and problems of project immersion teaching.

The article discusses the existing approaches to modelling decision-making processes in the analysis of risks in the innovation and investment sphere. The novelty of the research is the intellectualization problems solving of processes in the innovation and investment sphere on the basis of formal ontological models. Conclusions. The practical value of the presented results lies in the development and use of knowledge management system components for identifying and predicting problem situations in innovation and investment projects. The proposed integrated ontology can be used in the management of innovation and investment projects in various subject areas since it contains classes of concepts that have the status of a project activity standard. The developed ontological model makes it possible to develop software architecture for an intelligent decision support system, develop metadata and build a set of interrelated thesauri to support the semantics of end-user requests.

Managing complexity in projects: Extending the Cynefin framework

Recommendations for managing complexity in projects acknowledge different levels of complexity, but often neglect the importance of (non-)repetition. This paper uses the Cynefin framework, structuring problems along the levels of simple, complicated, complex, and chaotic, and the learning loop model as simple but practical tools to sort different project situations. Combining the degree of complexity with repeatability or uniqueness allows a typology of projects to guide management. Single-loop and double-loop learning from past experiences is restricted to the occurrence of similar situations, slicing, project management guidelines and frameworks to complicated projects. The more complex and novel the problem, the more likely that non-standard, non-algorithmic ways such as sensemaking, trial-and-error, and whole-systems approaches will yield satisfactory results. Expertise is useful for simple and complicated projects; however, for new and complex projects, experience, authority and trust, and recognition of abstract patterns (deutero learning) are more important.

An analysis of the effects of stakeholders management on IT project risks using Delphi and design of experiments methods

PurposeThis study aims to evaluate how stakeholders affect project risks by analyzing the connection between stakeholder management and risk management in the information technology (IT) project context.Design/methodology/approachUsing the Delphi method, interviews with IT project experts were conducted to examine four factors concerning stakeholder management and define probabilities for three risk variables. The design of experiments (DoE) method was applied for the design of the research instrument and data analysis.FindingsStakeholder engagement and communication with stakeholders have significant influence on the occurrence of negative risks, opportunities and the development of contingency strategies. These results provide project leaders with relevant data that better guide actions toward stakeholders and enhance project success probability.Originality/valueThis study clarifies important aspects of two main project management areas – stakeholder and risk management – in the IT projects context. This research also presented an unusual application for the DoE method which allows the subjective variables analysis by statistical tools and enables to explore factor influences on real project situations.

A novel mathematical programming model for multi-mode project portfolio selection and scheduling with flexible resources and due dates under interval-valued fuzzy random uncertainty

Resource management plays a pivotal role in project implementation success. The profitability of project-based companies not only relies on the right selection of project portfolio but also depends on accurate scheduling and resource management. This issue is addressed by optimal project portfolio selection and scheduling using flexible resource availability and projects’ due date. The motivation of flexible resources is to maximize cash flow by resource management and adding more projects to a portfolio by reinvesting the gain to increase resource availability during planning horizon. Flexible due date leads to perform more projects besides increasing the robustness of multiple projects. This study proposes a new linear structure of mixed-integer programming (MIP) model of project portfolio selection and scheduling considering the resource management, cash flow, tardiness cost, and robustness of multiple projects. Moreover, to a better description of real-life project situations, a new solution approach is introduced based on triangular interval-valued fuzzy random variables to incorporate both fuzziness and randomness uncertainties into mathematical programming models. To solve the proposed interval-valued fuzzy random model, a generalized credibility-based chance constraint measure is applied. The application and performance of proposed model are evaluated through different small to large-sized test problems and a real case study to tackle uncertainties and complexities explicitly.

The Impact of Covid-19 on Economic Growth

The Covid-19 pandemic in Indonesia since March 2020 has had an impact on negative economic growth for two quarters, namely minus 5.2 percent in the second quarter and minus 3.49 percent in the third quarter (yoy). Likewise, the economic growth of Kulon Progo Regency is expected to experience a drastic decline in 2021, after 2019/2019 had the highest growth reaching 18 percent.This article aims to analyze impact the Covid-19 pandemic has on the economy growth of Kulon Progo Regency per economic sector. This article also projections Kulon Progo's economic growth until 2024 using eleven projection methods. From the results of the projections carried out, the Gross Regional Domestic Product (GRDP) of Kulon Progo Regency in 2020 is predicted to slow down due to the Covid-19 pandemic case which affects almost all sectors. However, this decline only occurred in 2020, because in the following year several sectors are predicted to increase in line with the improving situation and operation of infrastructure projects. Several sectors that will increase, such as the transportation and warehousing sectors, due to normal activities at Yogyakarta International Airport (YIA). Based on the optimistic, moderate, and pessimistic scenario, Kulon Progo Regency's economic growth will continue to grow positively. There are two contributions of this research, firstly analyzing the impact of the pandemic and projecting the impact for the next 4 years and secondly, the projection is carried out using the best model of eleven methods.

Research on Reactive Power Compensation Configuration of Wind Farm Integration

The large-scale wind power integration into power system brings great impact on the grid voltage stability. In order to reduce the influences of grid-connected wind power on the power system and improve the safety of wind power integration, it is necessary to conduct research on reactive power compensation configuration of wind farm integration. Firstly, based on the actual situation of wind power project, the principle of reactive power compensation configuration is studied. Secondly, a theoretical calculation method of reactive power compensation configuration is proposed. On this basis, combined with the practical 300MW wind farm project, the reactive power compensation configuration example is analyzed. Finally, through the modeling and simulation by power system analysis software package (PSASP), the accuracy and effectiveness of the calculation method proposed by this paper are verified. This paper put forward a reactive power compensation configuration method which is applicable to all wind farms connected to the power system. This provides important support for voltage stability in the wind power integration project.

Study on the stability of slopes on both sides of highway in rock area under rainfall

In order to study the effect of rainfall on slope stability, by numerical simulation MIDAS/GTS finite element software, the influence of seepage stress coupling on slope stability under different rainfall conditions is calculated, and the measures of slope treatment and reinforcement are given according to the present situation of slope project. As a result, the safety factor is Fs=1.2 and is in a stable state. When rainfall is 2 h, the Fs= is 1.135, and the slope is in an unstable state. It shows that heavy rainfall accelerates the slope to the unstable state, and the instability is likely to occur with the continuous rainfall.

Risk Analysis of Tunnel Construction Scheme Change based on Field Monitoring and Numerical Analysis

Because of the surrounding environment restriction, some sections of the Lanzhou Metro Line 2 were forced to change the original open excavation method to the concealed excavation method. Among them, the ingate is the transitional section connecting the shaft and the cross passage, which is accompanied by the force conversion of the structure during the plan change process, and accidents are prone to occur. Combining this project situation, a construction scheme for turning the shaft from the cross passage into the ingate of mine line was proposed, and the finite element software is used to simulate the scheme. Numerical analysis shows that the stability of the tunnel supporting structure, shaft, and cross passage all meet the design requirements. The final ground settlement caused by the proposed construction method is 7.1 mm, and the settlement of the vault is 11.97 mm. It also turns out that the proposed construction method causes less deformation, and the method can be applied to the construction of the ingate conversion. The rationality of the method and numerical model was further verified by the comparison between the monitored data of surface settlement and vault sinking and numerical simulation results. Finally, the modified concealed excavation method and the original open excavation construction method is compared. It is concluded that the concealed excavation method is superior to the original open excavation method in terms of construction schedule, construction safety, economic benefits, and impact of construction on the surrounding environment. It indicates that it is a good choice to replace the construction method early if necessary. The successful implementation of this project can provide a reference for the design and implementation of similar urban subway projects.

Study of the impact of military factors and security threats on construction projects in Baghdad

Since 2003, the territory of Iraq there were many military conflicts and conducted a large number of terrorist operations, especially in the capital Baghdad.As a result, construction work in Baghdad began to increase after 2003, which led to an increase in construction risks. The most dangerous risks were military conflicts that occurred near the construction site and affected the workforce, equipment and the construction site itself. The purpose of the study is to identify the most important factors causing risks during construction in Baghdad due to military operations and terrorist threats, to assess the degree of impact of these factors on the duration, cost and quality of construction work, as well as on the safety of workers and the economic situation of construction enterprises. The object of the study is the Al-Radwaniyah residential complex under construction in Baghdad, which is located near the US military base. In the course of the study, the most important military factors causing risks were identified, and then a questionnaire survey was conducted to determine the degree of impact of these factors among employees of enterprises involved in the construction of the specified residential complex (contractors, engineers, consultants, etc.). After processing the results of the questionnaire, the risk factors were analysed using a statistical method. This made it possible to establish the degree of impact of each factor. The study showed the degree of influence of military factors that cause risks, in particular, on the safety and life of workers, the impact on the psychological and social state of the working staff in general. It was also found that sudden military clashes and terrorist operations in the study region have a negative impact on the economic and financial situation of the construction project, lead to a delay in the project and increase its cost. Therefore, it is necessary to look for solutions to avoid or reduce these factors in areas where there is a possibility of their sudden occurrence.

OPTIMIZATION OF INFRASTRUCTURE PROJECT PRODUCT PARAMETERS

The subject of the research is the means of determining the optimal set of parameters for the products of infrastructure projects. The aim of the study is to increase the efficiency of the implementation of infrastructure projects through the use of the developed model for substantiating the optimal parameters of their products. To achieve this goal, the following tasks have been solved: determination of the main options for autonomy of infrastructure projects; formalization of the dependences of the time, value and economic characteristics of infrastructure projects on the parameters of their products (infrastructure object) and the development of a conceptual model for optimizing these parameters; development of a mathematical model for optimizing the parameters of products of this category of projects. The following methods are used: system analysis, functional analysis, operations research. Results: it was found that the parameters of the product of infrastructure projects, on the one hand, ensure its commercial relevance, on the other hand, they determine the characteristics of the project (cost, risks, life cycle duration, etc.), which forms a complex system of requirements and restrictions for product parameters. As a result of the study, a conceptual and corresponding mathematical model for optimizing the parameters of an infrastructure project product has been developed for two situations: 1) for a situation of an autonomous infrastructure project, in which the infrastructure object being created does not imply commercial use, or its creation and commercial use is carried out within the framework of one project; 2) for a situation of two interconnected by means of a project infrastructure object - the creation of an object and its management (commercial use). Modeling is based on formalized dependences of the value, time and economic characteristics of the project on the parameters of its product. Conclusions: the model allows to determine at the initial stage of project development, within the possible range of variation, that set of parameters of its product that provides maximum value for stakeholders both when creating an infrastructure object and in the future when managing (operating) it.

Interpretation of Dejectedness and Insanity in Buddhist Exegetical Treatises

The subject of the paper is the moral aspect of interpretations of dejectedness (daurmanasya) and insanity (cittavikṣepa-unmāda) in the treatises Abhidharmakośa-bhāṣya by Vasubandhu (4-5th centuries) and Sphuṭārtha-abhidharmakośa-vyākhyā by Yaśomitra (8th century). Buddhist interpretation of these phenomena is based on the canonical postulate that only corporeal suffering is a karmic retribution (vipāka-phala). Dejectedness is treated by Buddhist exegetics as a peculiar trait of imagination (kalpanā) manifesting in the moment of mental construction of evil projective situations. Dejectedness can be good (kuśala) and evil (akuśala) dependent on personal moral position. Good dejectedness is repentance (kaukṛtya) for an undone good deed or sin done. Opposite to it is evil dejectedness. Insanity is treated as destruction of predicative (abhinirūpana) and mnestic (anusmaraṇa) functions of consciousness. This mental suffering is determined by karma in cases when attempts to destroy others consciousness had place in the past. Karmic retribution in these cases is corporeal suffering, or disbalance of gross elements, and insanity is the consequence of this disbalance.

Repopulating abandoned villages, new housing strategies for the pandemic

Il distanziamento sociale ha portato alla ribalta il tema di riabitare i borghi abbandonati e le aree interne. Le esperienze nazionali ci raccontano di realtà fatte di comunità, di politiche, di progetti che da anni cercano di dare risposta al tema delle aree interne e dei duemila borghi in stato di semi abbandono. L’attuale situazione pandemica ha accentuato la problematica dei luoghi dispersi e ha acceso i riflettori a questi insediamenti che effettivamente possono diventare una parziale risposta al Covid 19. Oggi bisogna domandarsi se il sistema insediativo del borgo o centro minore può essere una tipologia insediativa che può divenire un modello di vita in condizioni di protezione ovvero un ripiegamento sperimentale, una rivincita bucolica di chi da sempre combatte la metropoli ed il suo stile di vita.

Application of earned value method and earned schedule method for a residential apartment

Earned Schedule Management (ESM) gives an estimate of schedule and milestone achievement dates. Earned Value Management (EVM) assists to follow the project performance by giving the schedule variance, cost variance and their performance index. EVM &ESM helps the project manager to foresee cost and schedule for the real project. The objective of this study is to apply EVM & ESM to the real time residential apartment project which is upcoming in Bengaluru, Karnataka, India and then to compare the results of two deterministic forecasting methods EVM and ESM. The EVM and ESM parameters are generated by using the data procured from the planning department. It shows much fluctuation in the project performance but the last months (M10) results reveal that the project is behind schedule, unfavorable budget and needs more amelioration. The project has an unfavorable Cost Variance of -0.91(budget in crores of INR, 1 crore = 10millions)) and schedule variance of -6.71months. It is also observed from the results and actual project situations that Earned Value and Earned Schedule methods in conjunction gives more accurate interpretation than using each of them detachedly.

THE PLACE OF FRIENDLY RELATIONS IN THE FORMATION OF YOUNG PEOPLE'S IDEAS ABOUT THE GREAT PATRIOTIC WAR

The article presents the results of a secondary analysis of data from the study "The Attitude of students to the Great Patriotic war", conducted on the initiative of the Russian society of sociologists, by a research team led by Yuri Vishnevsky, as well as research materials from the Public opinion Foundation. The author, based on the interpretation of the respondents 'answers to the questionnaire questions:" who do you talk to most often about the great Patriotic war? And what would your friends do (in the context of: "What would your friends do if the war started?")", - analyzes the place of friendly relations in the formation of modern youth's ideas about the war of the Soviet people in 1941-1945. Regardless of the religion (Orthodoxy, Islam, Buddhism, atheism), the possible professional trajectory, as well as the specialty acquired at the University (technical, humanitarian, socio-economic, natural science), the phenomenon of friendship plays a significant role in shaping the worldview of young people. The article assesses the effectiveness of using such a methodological technique as a projective situation in a sociological survey, which allows showing the attitude to patriotism through the hypothetical behavior of friends, and evaluating the possible vector of actions in a hypothetical, critical situation limited by certain circumstances and conditions. There is freedom of assessment and independence of respondents positions. Proposals are formulated to improve the methodological and content apparatus of future research. Possible directions of the state policy on search for modern forms of additional education, volunteer projects that involve young people in the process of active participation in the events and results of the second world war and increase the interest of young people in obtaining objective data on the history of Russia are noted.
