Dr. Ashenhurst set the tone of the session by saying that the panel would discuss systems analysis in the industrial management sense, "With a view toward coordinating educational programs with management needs".
Abstract Sustainable development requires disruptive changes and radical innovations, and the capability to deliver this in relation to adapt to a sustainable development is needed in mature large industrial companies. Integration between sustainability and business development is needed, which the Circular Economy model offers. Circular Economy is little implemented in practice, and in the present paper barriers to a transition to Circular Economy is identified. Barriers are financial, structural, operational, attitudinal and technological. They are also, as analyzed in relation to innovation management, characterized by a need to increase integration between a number of different perspectives and domains in industry.

Ecological footprint calculations evaluate sustainability by examining natural resources. The ecological footprint obtained by calculating the number of natural resources per person provides information about the amount of waste produced as well as the natural resources consumed and examines the sustainability of living conditions in the world in this respect. The ecological footprint is one of the frequently encountered topics in the literature in terms of the analysis of environmental impacts. This study examines the factors influencing the Ecological Footprint in Turkey. Using annual data between 1980 and 2018, the relationship of renewable energy consumption, human capital and urbanization variables to the Ecological Footprint is examined. The Fractional Fourier Augmented Dickey Fuller Unit Root Test and the Fourier Autoregressive Distributed Lag Bound Test is used in the study. There is a statistically significant relationship between the renewable energy, human capital and urbanization variables and the Ecological Footprint. When the outputs obtained in the study are examined, it is seen that the variables affect the ecological footprint. The increased value of these variables can be used to explain why the Ecological Footprint increased. Increasing industrial activities due to globalization and technological developments, increasing vehicle traffic in cities due to population growth, unplanned urbanization and destruction of green areas due to the sheltering needs of the increasing population, inability of recycling facilities to adapt to the increasing population and unplanned waste management, etc. factors can increase the ecological footprint. However, as urbanization increases, if a correct plan is drawn by taking these factors into consideration, the negative correlation between the ecological footprint and urbanization can be explained. Within the determined plan; Wastewater management, protection of green areas, prevention of unplanned urbanization and efficient use of resources are explanatory at this point. The empirical findings have important policy implications. According to these policy implications, to offset the effects on the ecological footprint, educational activities to raise environmental awareness and adopt energy-efficient lifestyles should be given due importance, various incentives and supports should be implemented and a green-based lifestyle.
The problem of simulation of efficient ducted fan type propulsors is considered. From experience of operation of twin blades in fantails of helicopters, it is known that this configuration creates less noise compared to a uniform arrangement of the blades around the circumference. However, the flow behind such fan is less uniform than that of a conventional ducted fan. For multicopter-type unmanned aircraft and air taxis, the key problem is flight in take-off and landing modes as well as acoustic and vortex fields created by propulsors in these modes. The decrease in the noise level in propellers with twin blades can potentially be accompanied by an increase in non-stationary vortex effects on the aircraft as well as a decrease in specific thrust. The objectives were to develop a method for simulation of ducted fan propellers in the takeoff and landing mode, to determine the optimal angle between the blades, and to compare a ducted fan with twin X-shaped blades to conventional blade position. Turbulent flows were calculated using transient Reynold-averaged Navier-Stokes equations, complemented by SST turbulence model, and large eddy simulation with WALE subgrid viscosity model. The calculations used the modification γ–Reθ Transition SST of the Langtry-Menter turbulence model, where there are relations for the intermittency criterion, which made it possible to consider the laminar-turbulent transition and the appearance of thin laminar separation bubbles that affect both the thrust of the propeller and the nonuniformity of the flow behind it. Testing was carried out on four-bladed propellers according to the known results of the TsAGI reference experiments. Testing of the γ–Reθ Transition SST Langtry-Menter turbulence model showed that it reproduces the dependence of the thrust coefficient and power factor on the blade angle better than the standard SST model. Calculations have shown that there is a clearly defined optimum angle between the paired blades. A comparison of three-bladed, six-bladed single and six-bladed propellers with twin blades showed that the latter option has slightly better thrust characteristics and creates a significantly lower noise level on the ground. The studied characteristics of ducted fans demonstrate the prospects for the use of propellers with twin blades in aircraft with vertical takeoff and landing. The developed numerical method can be directly used for industrial calculations of propellers and fans.
Renewable energy sources, especially wind energy, are to play a larger role in providing electricity to industrial and domestic consumers. This is already the case today for a number of European countries, closely followed by the US and high growth countries, for example, Brazil, India and China. There exist a number of technological, environmental and political challenges linked to supplementing existing electricity generation capacities with wind energy. Here, mathematicians and statisticians could make a substantial contribution at the interface of meteorology and decision-making, in connection with the generation of forecasts tailored to the various operational decision problems involved. Indeed, while wind energy may be seen as an environmentally friendly source of energy, full benefits from its usage can only be obtained if one is able to accommodate its variability and limited predictability. Based on a short presentation of its physical basics, the importance of considering wind power generation as a stochastic process is motivated. After describing representative operational decision-making problems for both market participants and system operators, it is underlined that forecasts should be issued in a probabilistic framework. Even though, eventually, the forecaster may only communicate single-valued predictions. The existing approaches to wind power forecasting are subsequently described, with focus on single-valued predictions, predictive marginal densities and space-time trajectories. Upcoming challenges related to generating improved and new types of forecasts, as well as their verification and value to forecast users, are finally discussed.

Introduction
The factor of textual coherence and sentence relation are divided into three categories according to Halliday and Hasan:
A) Lexical factor: including repetition, synergy and semantic domains.
B) Grammatical factors: including referral, replacement and deletion.
C) Connective factors: including conjunctions (Yahaghi and Fallahi, 2011, p. 331).
New linguists, in the course of their early studies, have relied only on the description of less linguistic units and have not paid attention to the study and analysis of disciplines beyond such as in the critique of these research approaches (De bougrand and Dressler, 1981, p. 21). Gradually, with the development of linguistic research and the development of new theories, Noam Chamsky's rotational method, became a concept between sentences, and the basic need for study was concentrated within the organization of the text so that the text could be studied by linguists as a larger linguistic unit. (Ibid 104-130).
As a result, it led to the discovery of semantic relationships between elements of language which arise from the function of elements of coherence in the text.
Methodology
Since from the end of 20th century, a more detailed study of speech has been opened especially with patterns such as the pattern of cohesion and on the other hand, Khaghani in Persian poetry is a symbol of the strength and stability of poetic speech in the form of Ode.
One should examine to see if the pattern of coherence confirms the coherence of Khaghani's speech. In the prevalence of some fascinations, it seems necessary to see and explore the magnificent Persian text from new perspectives in order to show their originality' strength and coherence.
Discussion
In 1976 Halliday and Hasan divided English text cohesion tools into three categories: Grammatical tools including “referral”, “substitution” and “deletion”. Link tools including conjunctions; and lexical tools including repetition. In 1985 they expanded this division into another joint work.
It is the coherence consistency and integrity of the text that keeps the components of the text together; That is the meaning of lexical units within each sentence depends on the other units within the same sentence (Taki, 1999, p.73-81).
Text coherence refers to the set of links and relationships that exist between the components of the text. These links and relationships distinguish the text from randomly stacked sentences and turn it into a coherent whole (Lotfipur, 1995, p. 110). Vocabulary coherence based on the relationship that lexical units of language have with each other in terms of the content of their meanings and the text trough these relationships can be continuous and coherent (Mohajer & Nabavi, 2014, p. 64). Word has no meaning in isolation. The meaning of a simple or compound word is related to other words in the language. The main task of semantics is the clarify words and determine these semantic relations (Tarask, 2001, p. 18).
Recursion has the highest value among the elements of other words and increase the musical level of the poem, the stability of the words, the unity of the subject or the embodiment images and poetic emotions and feelings and the single theme and solidarity of the verses and connect them with chains (yavari, 2000). Recursion comes in several forms: repetition, contradiction, semantic inclusion, synonym.
One of the factors of the lexical coherence in the text is the factor for repetition. According to Halliday, repetition is the most obvious type of lexical coherence. The cohesive factor of repetition includes all morphological construction of a word (yavari, 2018, p. 163-192).
In Khaghni's view like the formalists, the word has a special importance to the extent that various literary techniques such as: prosody, repetition of sounds, repetition of syllable in words, etc. As a tool to draw the reader's attentions to the word element (Alavi Moghaddam, 1995). The thirst for word choice is clearly evident in Khaghani's words (Tajlil & Musavi, 2014).
In this Khaghani's poem, 41 words are repeated more than once. The most commonly used word is morning (It is the most frequent word in this poem). Khaghani has been called the poet of morning. Maybe that is why he pays attention to the morning and sunrise in his poems.
Conclusion
Contemporary patterns in literary studies are clearly arguments for commenting on literary topics. One of these models is the model of Halliday and Hasan cohesion, which was reviewed by Hasan sometime after its publication and was finally presented by Halliday and Hasan shortly after. For decades, formal studies based on this model have become increasingly important. On the other hand, the importance and success of Khaghani in Persian has always been raised. In this research, using the evolved theory of coherence of Halliday and Hasan (1985) in role-oriented linguistics; analysis, coherence and continuity in verses of Khaghani's poem have been done to determine how the semantic connection of cohesive chains has been realized in this poem.
According to this theory, the coherence of the relations between elements is the constructor of the text, but it is not enough just to achieve the coherence factors in the texts; rather after showing these factors, it is necessary to examine the coherence of the text, based on coherence coordination. This study, following the achievement of coherence of the factors and coherence of the text of the poem, led to the conclusion that Khaghani's verses have a high coherence according to Halliday model. Although the strength of the structure of Khaghani's poetry does not need to be confirmed by such models but it is a conclusive argument and a valid argument that shows that the patterns favored by modern scholars also confirm the coherence of the words of the greats of Persian literature.
According to the collected analysis materials, the following contents were obtained. Repetition and reference have the highest frequency in the issue of coherence of Khaghni's logic poem. In the topic of repetition, the highest frequency of words, revolved around the following axes:
Topics related to religion: God, Guidance, Baggage, futurity, Clerics.
Topics related to nature: Morning, sky, night, sun, moon.
3.Vocabulary related to war: Cousin, dagger, armor, razor, ring, punch, kidnapping.
4.Topics related to clothing: Cloaks, robes, masks, hats.
It is as if Khaghani wants to sing the epic of the sultan of religion instead of the epic of sultan of the time and show us a deep alternative. In this axis, he combines all the elements of nature to achieve his goal. The method of Haliday and Hasan in the Latin articles that are available and in the Persian articles that have been published in prestigious academic journals in the last 35 years is the first case study- Khaghani's poem- is translated into text and then into words. and are checked. This method is very accurate in this regard and according to this model, we can speak with certainty about the coherence of Khaghani's speech.
Also, in response to the questions of expression of the problem, it was found that new patterns for examining the ancient texts are not prohibited and there is no problem and the firmness of Khaghani's speech, which is clear for Persian literature elites, was proved by this pattern. It was also answered that the use of modern patterns is not a problem for the study of ancient texts. This pattern which has good accuracy and detail, is suitable for the study of Khaghani's poem.
Organizational behaviour, change and effectiveness. Corporate culture, Fine Arts
The Corona Virus Pandemic forces most organizations to implement systems and policies that are adjusted to gov-ernment regulations and appeals, including work from home, including at a research institute in private universi-typies in Indonesia. For the systems and policies to be implemented effectively, the leadership makes adjustments, especially in managing communications. Communication management is an important point during this transi-tional period because it has an impact on the coordination and results of work. Ineffective communication causes the institution's performance to be less than optimal. The purpose of this research is to describe the practice of communication management and coordination carried out by the leadership of an institution at a private university in Jakarta. The research method chosen was a case study approach, 11 informants were determined by purposive and snowball sampling. The results of this research show that the communication and coordination carried out by the leadership of the institution is not optimal, besides that it is limited to taking the initiative in confirming and providing a response, resulting in delays in completing their work. The fact in the field of leadership has not ad-justed the style of communication and coordination during the new normal. Comprehensive communication and coordination skills need serious attention because these abilities have an impact on institutions in building a cul-ture of synergy.
