The Effect of Investment Risk, Macroeconomics on Stock Prices in IPO Companies during the Covid-19 Pandemic
Authors: Supriyanto Supriyanto , Alexandri Mohammad Benny , Novel Nurillah Jamil Achmawati
Published: April 2022

Rapid technological advances and the wide dissemination of information, have provided great advantages and disadvantages for various aspects. Economic growth, the Covid-19 phenomenon, and investment risks, especially in Indonesia, are factors that are affected by technological advances. Indonesia's economic growth in the second quarter of 2021 experienced a 5.8% higher increase compared to the previous year which was only 5.7%. The growth and development of the capital market in Indonesia is one of the indicators of increasing economic growth. The growth and development of the capital market determines the progress of a country's economy (Muklis, 2016). Since the announcement of the first case of Corona patients in Indonesia on March 2, 2020 which began to spread, the Indonesian government has taken steps to urge the public to stay at home, isolate themselves and reduce gathering activities or maintain distance. With this appeal, several companies, both small and large companies, were forced to temporarily close their businesses, places of worship closed and schools closed. This precaution has slowed the Indonesian economy and the world economy. This happened because the people's purchasing power weakened, resulting in a decrease in company income and fluctuating investor interest, so the company reduced the number of workers to balance declining activities and the causes of investment risk. So this study tries to answer the following research questions (1) Does investment risk affect stock prices? (2) Does macroeconomics affect stock prices? (3) How do stock prices affect the relationship between investment risk and macroeconomics? In this study, a sample of 74 companies had IPOs during the Covid-19 pandemic. The least squares technique (PLS) was used. From these findings, the use of leverage indicators in investment risk has a significant effect on stock prices. The results also show that leverage and exchange rates have a mediating relationship between investment risk and macroeconomics.

Published: April 2022

Nowadays, mobile devices are important devices especially in business sectors and has led to the development of mobile commerce to engage in online transactions (Zheng, Men, Yang, & Gong, 2019). Mobile commerce has unique features compared to the e-commerce such as ubiquity, interactivity, localization services, and usage patterns (Wang, Ou, & Chen, 2019) In addition, M-commerce has important implications for service providers to construct effective services through key factors of m-commerce adoption in order to satisfy customers (Hsu & Yeh, 2018). According to Khalifa and Shen (2008), m-commerce covers a large number of services, including mobile financial services (m-banking, m-payment, and m-brokering), mobile shopping (m-retailing, m-ticketing, and m-auctions) and mobile entertainment (m-gaming, m-music, m-video, and m-betting). In Malaysia, m-commerce is still at the early stage and there is a limited number of studies on m-commerce in Malaysia (Krishna et al., 2017). Nevertheless, limited studies have scrutinized the relationship between university students and m-commerce applications, particularly in the aspect of transaction purposes.

Leaders' Emotional Intelligence Influencing Employees' Emotions: An Empirical Investigation in the Public Sector
Authors: Hassan Farihah , Sharip Sharfizie Mohd , Ibrahim Siti Sara , Awang Marinah , Fadzil Mohd Afif Mohd
Published: April 2022

Emotional Intelligence (EI) can be defined as recognising our own and others' feelings, motivating ourselves, and effectively managing emotions in ourselves and relationships (Goleman, 2009). Emotional intelligence has garnered much attention in management literature, particularly in the leadership domain, apart from the increasing number of studies in the industrial-organisational psychology discipline. Emotional intelligence is linked to observing team members' behaviour, adjusting the team's direction, and encouraging and convincing members, all of which are crucial in developing effective leadership (Lehner, 2020). Effective leaders may show employees how to complete their obligations more efficiently and effectively and provide solutions to complex problems that they cannot solve on their own. Furthermore, effective leaders are concerned with ethics since ethical leaders are significant with the fair treatment of their subordinates and two-way communication, significantly minimising stress and emotional distress among employees (Lee et al., 2021).

Methodology for Measuring the Benefits of Participation in Business Clusters
Authors: Dmuchowski Robert , Szmitka Stanisław
Published: April 2022

Running a business in the complex and global world requires cooperation of entities with different complementary resources and competences. A socio-economic organization which wishes to be competitive in the modern market must possess proper human, financial, material and information resources and be able to use them in the most effective way. A significant element in creating a network of connections is the absorption of knowledge and its skillful use linked with shaping innovation. Stimulation of the flow of knowledge between cooperating entities increases the level of innovation of undertaken projects. Enterprises and institutions that join together in cluster initiatives bring their material potentials, skills and experience in order to survive in a competitive market (most often small and medium-sized enterprises, scientific and research institutions) and to multiply the possibilities of achieving benefits. The accepted thesis of the article which claims that new, cooperating, innovative inter-organizational networks supported by local institutions contribute to an increase of their competitiveness in the market does not require special justification. However, the research problem is to indicate the methods by which it is possible to assess if participation in a business cluster brings benefits in specific areas of activity.The starting point for considerations in the presented study is the assumption that participation in clusters provides economic, social and scientific entities with economic or marketing benefits as well as knowledge development and socio-economic revival of a region. The main scientific inquiry, not only for the purposes of this thesis but also knowledge necessary for managers, is the effectiveness level of the adopted project. The aim of the article is to present research methods that can be used to assess the benefits that individual organizational entities achieve due to participation in a business cluster or a cluster initiative.

Published: April 2022

addition to providing a livelihood, this activity allows the individual to play a role in society, so it also plays a vital role in identity and self-esteem, since aspects such as rationality, happiness and the human will to serve other members of society are involved (Bastando, 2014). Given the above, it can be said that the subjective well-being implied by work is essential, but not the only one. The Human Development Index proposed by the United Nations Development Programme takes a comprehensive view of the material and immaterial capabilities that make up the well-being of individuals and, among them, are knowledge, healthy living and maintaining a decent life, which is why it is essential to ensure health, emotional ties with others and the satisfaction of basic needs, both physical and psychological (Aedo et al., 2020). When the individual performs a function in society, he or she manifests some degree of satisfaction that deserves to be analysed, which is why, in recent years, the importance attributed to employee satisfaction has increased considerably (Akram et al., 2021; Galvan-Vela et al., 2021). Being responsible for achieving business goals, employees are appreciated as the most valuable resource (Ali and Anwar, 2021; Stefurak et al., 2020). Moreover, the talent and enthusiasm of human resources enable the company to survive in dynamic and changing environments (Galvan-Vela et al., 2021), conditions that are present in most economic sectors today.

Students' Financial Literacy: Digital Financial Literacy Perspective
Authors: Rahim Nurhazrina Mat , Ali Norli , Adnan Mohd Fairuz
Published: April 2022

Financial instability and a lack of financial literacy are commonly blamed for the growth in bankruptcy and social concerns among the younger generation. Between 2017 and October 2021, 36,173 Malaysians aged 18 to 44 were declared bankrupt, according to the latest numbers from the Malaysian Department of Insolvency. Furthermore, Selangor had the highest number of instances (25 per cent) (MdI, 2021). This problem offers a substantial obstacle to achieving the Sustainable Development Goals (SDGs), which aim to reduce inequality and promote social and economic inclusion for all citizens. Additionally, due to the recent outbreak of Pandemic COVID-19, financial transactions have shifted from physical to electronic. This circumstance creates an additional risk since it has resulted in the ease of conducting financial transactions. Thus, it is vital for students to have a solid understanding and awareness of online transactions, commonly referred to as digital financial literacy (DFL), to practice sound financial management. Financial literacy deficiencies (both fundamental and digital) would pose a substantial threat to individual financial management. As a result, assessing current university students' financial literacy is crucial. Most of these students will confront financial challenges such as budgeting for study-related costs using the scholarship or pocket money they earned. This research aims to determine the degree of financial literacy (both basic and digital) among Selangor university students.

Genetic Algorithm Approach for Image Fusion: A Simple Method and Block Method
Authors:   Assistant Professor, Department of Data Structures and Algorithms, Pimpri Chinchwad College of Engineering, Pune (Maharashtra), India., Kulkarni Dr. Jyoti S.
Published: April 2022

The sensors available nowadays are not generating images of all objects in a scene with the same clarity at various distances. The progress in sensor technology improved the quality of images over recent years. However, the target data generated by a single image is limited. For merging information from multiple input images, image fusion is used. The basis of image fusion is on the image acquisition as well as on the level of processing and under this many image fusion techniques are available. Several input image acquisition techniques are available such as multisensor, multifocus, and multitemporal. Also, image fusion is performed in four different stages. These levels are the level of the signal, pixel level, level of feature, and level of decision-making. Further, the fusion methods are divided into two domains i.e spatial and frequency domains. The fusion in spatial domain images uses inputs directly to work on pixels, while the transition refers to frequency domain image fusion on input images before fusion. The limitation of spatial domain image fusion is spectral degradation. To overcome this limitation, the fusion of transform domain images is preferred which uses several transforms. The results generated by transform methods are superior to spatial domain methods. But there is a scope to improve the results or to find the optimized results. Optimization can be achieved by using evolutionary approaches. The evolutionary computation approach is an effective way of finding the required solution for a complex problem. An evolutionary algorithm is a guided random search used for optimization. The biological model of evolution and natural selection inspires it. The different types of evolutionary computing algorithms include Genetic algorithm, Genetic Programming, Evolutionary programming, Learning Classifier System, Ant Colony Optimization, Artificial Bee Colony Optimization, Particle Swarm Optimization, Evolution strategy, Swarm intelligence, Tabu Search, Cuckoo Search, etc. Three genetic algorithm-based image fusion techniques are proposed: a genetic algorithm with one population, a genetic algorithm with separate populations, and a block method. In the block method, an array of numbers in one chromosome is generated. The result obtained by the proposed techniques are compared with existing methods and observed that the results are improved. The graphical representation of performance parameters reflects that the block method is better.

Mobile Ad hoc Network is a self-organizing, infrastructure-free, distributed wireless networks made up of various mobile devices. Quality-of-Service routing is most difficult task in MANET due to inherent characteristics–for example frequent dynamic topology, node mobility, resource scarcity, absence of centralized control, etc as well. The QoS variables of any MANET routing algorithms determine its performance. QoS routing is process of routing packets from source (S) to destination (D) based on QoS resource constraints such as bandwidth, delay, packet loss rate, cost, security, link stability, and so on. Swarm intelligence, which mimics the collective behaviour of biological organisms to handle routing problems and improve QoS in the network, has been one of most popular studies for network routing in recent years. Particle Swarm Optimization algorithm (PSO), Genetic Algorithm (GA) and Ant Colony Optimization algorithm (ACO) have all been shown to be effective for developing routing algorithms by improving QoS metrics in ad hoc networks using Swarm Intelligence (SI). The primary objective of this comparative study paper is to improve QoS parameters by applying swarm intelligence to MANET routing algorithms. Swarm intelligence-based routing algorithms will be more promising for the specific nature of adhoc networks, outperforming in real scenarios/constraints/environmental conditions and will be tuned and simulated to obtain an efficient and effective MANET routing protocol. This paper investigates four potential pre-existing approaches proposed for MANET routing problems. These routing algorithms are evaluated using various performance metrics such as packet delivery ratio, routing overhead, link failure prevention, energy consumption, accuracy, and throughput, among others.

Authors:   Department of Electrical Engineering, Mid Kent College – Chatham – England., Al-Mahdawi Dr. Emad
Published: April 2022

In practice, energy management encompasses several activities that give objective data on the principal users of fuel and energy, the energy efficiency of various developments and certain types of products, and energy conservation reserves. This research investigates the benefits and stages of EMS that must be adopted in Iraq. The work considers the significance of using EMS technology at Baghdad International Airport. Airport infrastructure necessitates much energy due to its vast size and particular design. Annually, the airport consumes nearly 9.2M KWh, costing 1.2 billion Iraqi Dinars/KWh. As Iraq's current energy crisis is massive, the energy audit will show an accurate picture of the energy consumption. EMS aims to increase the organisation's stability (including financial) and improve its competitive position by reducing costs and increasing management efficiency. The work has accomplished that Iraqi companies need a modern management strategy-energy consumption management. Traditional heads of departments must be updated to be active in fixing the organisation's energy issues. The EMS technology can identify conflicts and re-document structures. The technique also enables addressing any safety issues in the design phase. Therefore, this paper contributes to enhancing and developing the traditional Energy Management System in Iraq.
Image Fusion by a Hybrid Multiobjective Genetic Algorithm Technique
Authors:   Assistant Professor, Department of Data Struc-tures and Algorithms, Pimpri Chinchwad College of Engineering, Pune (Maharashtra), India., Kulkarni Dr. Jyoti S.
Published: April 2022

Sensors used in image acquisition. This sensor technology is going on upgrading as per user need or as per need of an application. Multiple sensors collect the information of their respective wavelength band. But one sensor is not sufficient to acquire the complete information of one scene. To gain the overall data of one part, it becomes essential to cartel the images from multiple sources. This is achieved through merging. It is the method of merging the data from dissimilar input sources to create a more informative image compared with an image from a single input source. These are multisensor photos e.g. panchromatic and multispectral images. The first image offers spatial records whereas the lateral image offers spectral data. Through visible inspections, the panchromatic photo is clearer than a multispectral photo however the grey shade image is. Articles are greater clear however now not recognized whereas multispectral picture displays one of a kind shades however performing distortion. So comparing the characteristics of these two images, the resultant image is greater explanatory than these enter images. Fusion is done using different transform methods as well as the genetic algorithm. Comparing the results obtained by these methods, the output image by the genetic algorithm is clearer. The feature of the resultant image is verified through parameters such as root mean square error, peak signal to noise ratio, mutual information, and spatial frequency. In the subjective analysis, some transform techniques also giving exact fused images. The hybrid approach combines the transform technique and a genetic algorithm is used for image fusion. This is again compared with genetic algorithm results. The same performance parameters are used. And it is observed that the hybrid genetic algorithm is superior to the genetic algorithm. Here the only root means square error parameter is considered under the fitness function of the genetic algorithm so only this parameter is far better than the remaining parameters. If we consider all parameters in the fitness function of the genetic algorithm then all parameters using a hybrid genetic algorithm will give better performance. This method is called a hybrid multiobjective genetic algorithm.

Emphysematous or gangrenous pancreatitis is a rare and fatal complication of acute necrotizing pancreatitis. It is characterised by the presence of gas in the necrotic pancreatic parenchyma and/or peripancreatic collections. The bacteria most often incriminated are gram-negative, notably E. coli, and the route of bacterial dissemination is hematogenous. It is a pathology that occurs in immunodepressed areas, particularly in diabetics. and it is rarely the mode of revelation of the latter, as was the case in our patient. Abdominal CT is the examination of choice for making the diagnosis. %. Its evolution depends on the precocity of antibiotic therapy, which must be aggressive to control the infection, and on percutaneous drainage or surgical debridement, and recovery is generally prolonged.

Introduction: The GINA and the ATS do not mention that the forced expiratory flow between 25% and 75% of forced vital capacity (FEF 25%-75%) play importance in evaluation of airflow obstruction in asthma. Objectives: To investigate whether the evaluation of the FEF25%-75% in children and adolescents with asthma sensibilized to house dust mites (HDM) plays an important hole in airway obstruction from small airways. Methods. A retrospective study was done in Hospital Municipal Jesus (Rio de Janeiro, Brazil). Thirty-four children and adolescents with asthma were enrolled between January 2016 and December 2019. The FEIA (Immuno CAP®) was used to measure total and specific IgE antibodies to HDM. Standard reference value for small airways diseases with FEF 25%-75% was considered abnormal if below at 65% of predicted with FEV1/FVC ratio above or equal at 80%. Results. There was a significant difference between the mean ages of the sensitized (n=26; 9.8±2.53) and non-sensitized participants (n=8; 7.75±1.28) to HDM (P=0.0353). Male and female sexes were not significant in both groups (P=0.3698 and P=0.3298, respectively). If the FEF 25%-75% (L/s) was not valued in our study, 62% of sensitized participants (44.27±9.26) and 38% not sensitized (56.62±16.56) to HDM would be considered “according to normal reference values” (t=1.86; P=0.0719). Conclusions. The asthma in this study presented an obstructive respiratory disorder of small airways, regardless of a sensitization or a non-sensitization to HDM. The obstructive respiratory disorder of small airways was present, even with normal spirometry in the evaluation of large airways.

Double-positive vasculitis with anti-polynuclear cytoplasm (ANCA) and anti-glomerular basement membrane (GBM) antibodies is a rare entity of systemic vasculitis defined by the presence of ANCA and anti-GBM antibodies. The gradual accumulation of clinical and therapeutic data shows the usefulness of identifying and differentiating this entity from the two vasculitis respectively associated with the isolated presence of each of these two antibodies. Indeed, the double-positive ANCA and anti-GBM vasculitis appears to associate the characteristics of the demography and the extra-renal and pulmonary involvement of the ANCA-associated vasculitis on the one hand, and of the histological type and severe renal prognosis of the anti-MBG vasculitis on the other hand, with the renal involvement which is the only involvement consistently observed in double-positive vasculitis [1]. The aim of this case is to describe the clinico-biological, histological and prognostic characteristics of this entity, in light of recent literature and ongoing therapeutic changes in the two eponymous vasculitis.

Annular pancreas is a rare congenital anomaly characterized by the presence of ectopic pancreatic tissue around the duodenum. Usually diagnosed in the neonatal period, the annular pancreas can be responsible for intestinal obstruction in 1% of cases. In adults it is asymptomatic in 50% of cases, as it can be responsible for duodenal stenosis, pancreatitis, or duodenal or gastric ulcerations. We report two cases of duodenal stenosis secondary to an annular pancreas diagnosed in two adults in whom a surgical bypass was performed allowing resolution of symptoms.

Purpose: To describe a case of myelodysplastic syndrom associated with bilateral retinal vein occlusion. Observations: A man in his 50s presented flashes and progressive drop of vision in both eyes with and feeling tired. He had no history of ophtalmic pathology. His medical history was negative for diabetes and hypertension. His initial best-corrected visual acuity was 20/200 OD and 20/25 OS. Anterior segment examination was normal. In fundus examination he had bilateral peripapillary flame-shaped and intraretinal hemorrhages in both eyes with macular hemorrage in the right eye. There was no vessel tortuosity. Fluorescein angiography of both eyes showed a good venous filling, no leakage, and no neovascularization.

The main aim of this study was to investigate the role of non-steroidal anti-inflammatory drugs in digestive bleeding in a hospital setting and in a context of social and security instability. Patients and methods: This was a prospective and analytical study that took place in the Hepato-Gastroenterology Department of the Gabriel TOURE University Hospital over a period of two years and included all patients hospitalized for digestive hemorrhage. These patients had benefited from the research of sociodemographic characteristics, the notion of taking non-steroidal anti-inflammatory drugs (dose and duration), a physical examination and a digestive endoscopy. Results: At the end of this study, 78 cases of non-steroidal anti-inflammatory drug use out of 210 patients hospitalized for digestive hemorrhage were recorded, i.e. a frequency of 37.1%. The mean age of our patients was 47.01±19.3 years with a sex ratio of 2.9. Housewives and farmers represented 28.2% and 20.5% respectively. Hematemesis was the reason for consultation in 71.8%. Digestive hemorrhage and smoking were the most common antecedents. Diclofenac was the most commonly used drug in 53.9% of cases, with bleeding occurring in the first week after taking the non-steroidal anti-inflammatory drug in 53.9% of cases. Signs of hypovolemic shock were frequently found. The GD ulcer was the cause found in 66.2% of cases. Hemorrhage occurred significantly (p=10-8) in the first week of taking non-steroidal anti-inflammatory drugs and was significantly associated with NSAID use. There was no statistically significant difference in the occurrence of death between the molecules. Conclusion: NSAID-induced GI bleeding in adults is one of the major GI emergencies and remains an important cause of morbidity and mortality.
