Do Investors Overreact to COVID-19 Outbreak? An Experimental Study Using Sequential Disclosures
Authors: Sulistiawan Dedhy , Feliana Yie Ke , Rudiawarni Felizia Arni , Grigorescu Adriana
Published: April 2023

This paper aims to investigate market participants' reactions to sequential information, presenting firm-specific news and market-wide information. Experimental study takes place in the COVID-19 pandemic era, as market-wide information representation. We also provide firm-specific information in the form of company fundamental information. The results show that participants, as representatives of retail investors, do not overreact to COVID-19. The recency effect dominates their decision-making. Neither firm-specific information nor market-wide information can eliminate the recency effect in decision making. Investors still provide valuations based on the latest information they receive. Another interesting finding in this study is that positive framing of information cannot mitigate the effects of bad news contained therein. Our findings contribute to the study of behavioral finance and corporate disclosure strategies. From the market participants' point of view, our results describe that investors' decisions are often not based on the information content but the latest information they received. From the company perspective, this research also contributes to the corporate disclosure strategy valued by investors based on how they disclose information to the public.

Authors: Sari Evi Thelia , Gryga Vitalli
Published: April 2023

The purpose of this study is to describe and examine the development of SMEs in Ukraine and Indonesia based on productivity factors of SMEs development measured SMEs contribution to the country’s GDP. The study is based on data from 2000 to 2014, on number of SMEs, contribution of SMEs to GDP, labor in SMEs sectors, exports and import contributions to GDP of each country. Under complex data with uncertainty, Fuzzy Inference System (FIS) was applied to modelling process in estimating the differences between SMEs development in Ukraine and Indonesia. FIS models show the needs to improve policies on SMEs in each country of this study. We found that SMEs intensity development in Ukraine needs more SMEs to increase contribution to GDP and stipulate economic growth. While in Indonesia, growth in quantities of either labors or numbers of SMEs can be problematic, so it should focus on labors quality. Trade openness e.g., ratio export and import to GDP, shows that while Ukraine’s SMEs contribution to GDP is lower, the ratio of Export and Import to GDP is increasing. Whereas Indonesia’s ratio of export and import to GDP increases along with the SMEs contribution to GDP. The policies to increase the intensity development of SMEs in both countries should focus on increasing the quality of labors hired in SMEs, increasing the numbers of SMEs, reviewing and selecting the commodities that are prioritized to export and import in enhancing the ratio of export and import to GDP.
Green Innovation for Competitiveness: Impact on GDP Growth in the European Union
Authors: Banelienė Rūta , Strazdas Rolandas
Published: April 2023

Since the start of the Industrial Revolution, the global climate has changed dramatically. Concentrations of greenhouse gases (GHGs) in the atmosphere have increased sharply, followed by an increase in global average temperatures. However, business activities related to environmental protection are mostly focused on the implementation of legal rules instead of voluntary initiatives such as green innovation due to doubts about costs and profit. The goal of this research is to identify the impact of green innovation on economic growth in an innovative environment and digitalization conditions by using sophisticated indexes and regression analysis. The results show that green innovations have a positive impact on economic growth in the European Union (EU). However, the impact of digitalization on economic growth is still under discussion and depends on qualitative aspects of coverage and how they are reflected in digitalization indicators. It is important to emphasize that the data of this empirical study only cover EU countries that are subject to EU regulation and have similar trends in the development and diffusion of green innovations. Non-EU countries may have different approaches and policies influencing the maturity and diffusion of green innovations. The results of this research provide a scientific basis for strategic planning at the national and business levels, encouraging a focus on the development of green innovation not only as a means of reducing the impact of climate change but also as a strategic direction for increasing competitiveness and economic growth.

Essential steel components with variable cross-section are fabricated from welded plates, which are primarily employed for the growth of the construction industry in beams according to the stress and stiffness requirements of the structure. Lateral-torsional buckling, in which the beam experiences non-uniform twisting and buckling about its weaker axis, is one of the most common failure modes. This dissertation focuses primarily on the lateral-torsional buckle of non-prismatic I-beams. The development of differential equations for deformation analysis of the non-prismatic beam. ANSYS results and deformation equation results are compared to validate the methodology. Using ANSYS, the lateral torsional buckling of a non-prismatic I-beam section with uniformly distributed load is analyzed. In finite element analyses, the solid element approach is used to determine the lateral buckling load for various cross-sections (β = 0.1 to 1.0) by analyzing their behavior. In addition, a stiffener is used to prevent lateral buckling, and the results are compared to a model without stiffeners.

Authors: Kuschel Linda , Rostam Darius
Published: April 2023

Ziel des UrhWissG von 2018 war es, das Urheberrecht den Anforderungen von Bildung und Forschung anzupassen. Dem 2022 verabschiedeten Evaluierungsbericht der Bundesregierung zufolge hat das Gesetz dieses Ziel insgesamt erreicht. Der Beitrag geht der Frage nach, ob damit die Akte „Urheberrecht für Bildung und Forschung“ geschlossen werden kann. Er zeigt Möglichkeiten auf, mit denen der Gesetzgeber mit wenig Aufwand die bisherigen Bemühungen vervollkommnen kann. Dazu gehört es, die Erlaubnis zur Nutzung von Presseerzeugnissen begrenzt auszuweiten, den prozentbasierten Umfang der erlaubten Nutzungen rechtssicher auszugestalten, eine Schrankengrundlage für das E-Lending zu schaffen, auf eine pauschale, aber stichprobenbasierte Vergütung in § 60h Abs. 3 UrhG umzustellen und Open Access-Publikationen über das Zweitnutzungsrecht in § 38 Abs. 4 UrhG zu stärken. Vertieft betrachtet wird zudem das umstrittene Verhältnis der gesetzlichen Erlaubnisse und Vergütungsansprüche zu vertraglichen Vereinbarungen, insbesondere im Fall von Open Access-Lizenzen.

Local Development Model as an Element of Regional Sustainable Strategy
Authors: Adamowicz Mieczysław
Published: April 2023

Regions constitute key elements of the territorial structure of any country. Internal differences in regions permit to distinguish subregional and local units in them, where economic and social activities are undertaken. Despite the internationalisation and globalisation processes, the importance of local development concept is growing. There are several factors influencing the growing role of local units in socio-economic development of regions. In many countries, local communities have a great autonomy in creating local development strategies and policies. Local endogenic strategies and policies create an important complementary activity to sustainable regional planning. The aim of the work is to present a theoretical background of the local economy and local development. Using the subject literature, the theoretical concepts, definitions and the results of local development were presented. Selected models and paradigms of local development as well as interrelations between dimensions of local sustainability and links with regional planning were presented and discussed as well.
Constrictive Pericarditis
Authors: Maria Lauri Francesco
Published: April 2023

Constrictive pericarditis (CP) is a challenging clinical scenario in which the heart muscle is entrapped by thick, fibrous, and frequently calcified pericardial layers. Whereas infectious diseases (mostly bacterial) had been observed as the main etiology in the last decades, nowadays, post-surgical or radiotherapy iatrogenic inflammation is becoming highly prevalent with the exception of developing countries and patients with immunodeficiency in which tuberculosis is still frequently observed. Clinically, progressive dyspnea and peripheral edema are present and frequently considered of unknown origin because of the diagnostic challenge that CP poses. As a matter of fact, a specific knowledge of echocardiography and right heart catheterization is essential to recognize constriction features. Moreover, a valuable support is provided by dedicated imaging modalities (mostly magnetic resonance). Complete surgical removal of the pericardium (pericardiectomy), when feasible and performed early, is associated with excellent symptomatic improvement. Unfortunately, in specific scenarios (radiation therapy) or when surgery is performed after severe constriction development, surgical outcomes are poor, and CP assumes the profile of an end-stage disease. This reinforces the unmet need of early detection of CP and the development of novel therapeutic strategies.

Published: April 2023

Perinatal asphyxia is one of the most frequent causes of perinatal morbidity, accounting for approximately 23% of neonatal deaths worldwide. Fetuses that suffer from hypoxia-ischemia are at high risk of developing multiorgan dysfunction, including the gut. Hypoxie-induced gut injury may result in adverse clinical outcomes, such as feeding intolerance and necrotizing enterocolitis. Increased permeability and subsequently an enhanced entry of bacteria and endotoxins into the systemic circulation can contribute to endotoxin aggression and further trigger numerous diseases. The aim of study is to investigate the effect of perinatal asphyxia on the integrity of the intestinal barrier and the state of antiendotoxin immunity. The study included preterm neonates exposed to perinatal asphyxia, who were comparable with non-asphyxiated infants. The concentrations of intestinal mucosa barrier injury markers (intestinal fatty acid binding protein, liver fatty acid protein, lipopolysaccharide binding protein), neurospecific proteins (neurospesific enolase, NR-2 antibodies), and also endothelial dysfunction markers (endothelin-1, nitric oxide) were determined in serum of included neonates on day of 1 and 7. The high risk of intestinal mucosal injury in newborn exposed to perinatal asphyxia decreases the level of antiendotoxic immunity and should be considered as an unfavorable factor for sepsis.
The Impacts of Climate Change and Wetland Restoration on the Water Balance Components of the Coastal Wetland
Authors: A. Ghazal Kariem
Published: April 2023

The coastal wetlands represent the critical interface between the terrestrial and ocean zones, which have gained vital importance in terms of economic and environmental aspects. Land cover change (LU) and climate change (CC) are considered the determinant factors for the changes in nutrient fluxes, thermal energy, and water balance components (WBCs). These factors are also expected to affect each other through interaction process effects. An essential tool that may be used to evaluate the sustainability and availability of water resources for food security and the ecological health of coastal zones is a hydrological modeling technique. The Heeia coastal wetlands in Hawaii, USA, are used as a case study in this study to evaluate the effects of LU and CC on WBCs.
Percutaneous Approach to Pericardial Disease Management
Authors: Hartnett Jack , Armstrong Richard , Brandon Lisa , Jneid Hani , F. Palacios Igor , O. Maree Andrew
Published: April 2023

Percutaneous access of the pericardial space is increasingly sought. This is not only due to growing prevalence of pericardial effusions and cardiac tamponade, but also the emerging diagnostic and therapeutic potential of the pericardial space for mapping and ablation of arrhythmogenic circuits, biopsy, and drug delivery. Although increasingly performed, percutaneous pericardiocentesis remains a technically challenging procedure with potentially life-threatening complications. Consequently, management of patients with pericardial disease is highly complex. In this chapter we outline a step-by-step approach to percutaneous pericardiocentesis and the required specialised management of pericardial disease patients. Procedural complications are discussed along with their alleviating therapeutic strategies. Furthermore, we describe approaches to the prevention and management of recurrent pericardial effusion including diagnostic and therapeutic procedures such as percutaneous balloon pericardiotomy and intra-pericardial delivery of chemotherapeutics and sclerosing agents.
Perspective Chapter: Hydrogel Draw Agent Desalination Systems – Outlook
Authors: Fayer Alexander
Published: April 2023

The chapter intends to discuss an application of hydrogel material as draw agent for a forward osmosis desalination system. This refers to systems that allow a continuous process of extraction of desalinated water with low energy costs and minimal environmental pollution. One of the most prominent properties of hydrogel materials is their ability to spontaneously absorb large quantities of water from saline solution separated by a semipermeable membrane. This process is energetically favorable due to the difference in the chemical potentials of water in the solution and hydrogel. Thermodynamic equilibrium between hydrogel and external saline solution corresponds to the strictly defined amount of water retained by the hydrogel in the given conditions. The excess pressure of water in hydrogel relative to the pressure of the pure external in this state is defined as the osmotic pressure difference. In contrast to the absorption of water molecules by hydrogel, their extraction is usually a process that requires large energy consumption and disruption of the continuity of the desalination cycle. However, known several opportunities to overcome this bottleneck and they are discussed in detail.
Ethanol Inhalation in Treatment and Prevention of Coronavirus Disease (COVID-19)
Authors: Amoushahi Ali
Published: April 2023

The goal of this study was to determine if nebulized ethanol (EtOH) is safe and effective in treating COVID-19. A randomized controlled trial was carried out on 99 symptomatic and RT-PCR-positive patients admitted to a hospital that were given Remdesivir and Dexamethasone. They were randomly given either a 35% EtOH spray (intervention group, IG) or distilled water spray (control group, CG). For a week, each group underwent three nebulizer puffs every 6 hours. Global Symptomatic Score (GSS) comparisons between the two groups at the initial visit and on days 3, 7, and 14. Secondary outcomes include the readmission rate and the Clinical Status Scale (CSS), a seven-point ordinal scale that ranges from death to full recovery. The intervention and control groups, respectively included 44 and 55 patients. The GSS and CSS considerably improved in the IG, despite the fact that there was no difference at admission (p = 0.016 and p = 0.001, respectively) (Zero vs. 10.9%; P = 0.02). The IG readmission rate was much reduced. Inhaled-nebulized EtOH responds well in quickly improving the clinical status and limiting the need for further therapy. Further investigation into the therapeutic and preventative properties of EtOH is advised due to its affordability, availability, and lack of/tolerable side effects.

Background: Shingles is a common skin infection, caused by the latent Varicella zoster virus in the paraspinal cranial nerve ganglia, when there are favorable factors such as immunosuppression makes the virus active again. The disease greatly affects the patient's quality of life. Objectives: Survey to determine clinical manifestations, correlative factors and evaluate the results of topical treatment of herpes zoster with He-Ne laser combination at Can Tho DermatoVenereology Hospital in 2021. Methods: Cross-sectional descriptive study with 75 Zona patients who were treated according to the usual regimen and combined with local He-Ne laser at Can Tho Dermato-Venereology Hospital. Results: The disease that occurs in the age group over 60 years old is the most common (56%). Pain was found in 100% of patients. The vesicle lesions accounted for the highest rate (84%), the most commonly affected area was trunk 38.7%. Mild level accounted for 57.3%. The group of patients with more than 5 days of illness had a longer hospital stay (42.9%). After treatment with He-Ne laser, 66.7% had good treatment results. Conclusions: Herpes zoster disease occurs at any age, but mainly in the elderly with vesicles and pain in most of the patients, commonly on the trunk and head-face-neck area. Attention should be paid to the time before admission, the state of co-infection because they reduce the response to treatment. The combination of He-Ne laser with conventional regimens helped to cure and effectively reduce pain in Herpes Zoster patients.

Objective The efficient use of wards intended for elective surgeries is essential to resolve cases on the surgical waiting list. This study aims to estimate the efficiency of ward use in the Chilean public health system between 2018 and 2021. Methods The design was an ecological study. Section A.21 of the database constructed by the monthly statistical summaries that each public health network facility reported to the Ministry of Health between 2018 and 2021 was analyzed. Data from subsections A, E and F were extracted: ward staffing, total elective surgeries by specialty, number and causes of suspension of elective surgeries. Then, the surgical performance during working hours and the percentage of hourly occupancy for a working day was estimated. Additionally, an analysis was made by region with data from 2021. Results The percentage of elective wards in use ranged from 81.1% to 94.1%, while those enabled for those staffing ranged from 70.5% to 90.4% during 2018 and 2021. The total number of surgeries was highest in 2019 (n = 416 339), but for 2018, 2020, and 2021 it ranged from 259 000 to 297 000. Suspensions varied between 10.8% (2019) and 6.9% (2021), with the leading cause being patient-related. When analyzing the number of cases canceled monthly by facility, we saw that the leading cause was trade union-related. The maximum throughput of a ward intended for elective surgery was reached in 2019 and was 2.5 surgeries; in 2018, 2020 and 2021, the throughput borders on two surgeries per ward enabled for elective surgery. The percentage of ward time occupied during working hours by contract day varies between 80.7% (2018) and 56.8% (2020). Conclusions All the parameters found and estimated in this study show that there is an inefficient utilization of operating rooms in Chilean public healthcare facilities.

This qualitative and documentary research analyzes the significant advances that production and operations have had over time, seeking to establish the management approach's progress in each of the historical stages. It is possible to confirm that this has evolved from a perspective focused on manufacturing to a philosophy focused on a comprehensive view of the supply chain. This highlights the main obstacles to facing current challenges and, at the same time, points out the almost hegemonic short-term vision that has characterized production and operations management throughout the 20th century, as opposed to the demand current broader perspective.

Published: April 2023

This descriptive research aims to examine the values education in a secondary school via teacher views. The data collection method of the research is mixed method as it includes both quantitative and qualitative data collection techniques. The study group of the research consists of teachers at a public secondary school in Aydın. Data were collected from 15 teachers by questionnaire and five teachers by interviews. Descriptive analysis such as percentage, frequency and mean of the obtained data were calculated. As for the findings; values education defines as social benefit and moral development. The influence of the parents on values education is more than the influence of media, peers, school or teacher. The type of TV program watched by students, the role model of teachers and the reason for using the internet have influence on the development of values. It has been concluded that the verbal weighted lessons are more effective in the development of the values of the students, and that the goals/acquisitions related to values education cannot be reached at the desired level.

Sadar akan berbagai kelemahan yang terdapat dalam rumusan UUD 1945 sebelum amandemen, pada tahun 1999 MPR mulai melakukan amandemen terhadap UUD hingga tahun 2002 sebanyak 4 kali. Penelitian ini akan mengkaji bagaimana perwujudan dari paham konstitusionalisme dari hasil amandemen UUD 1945 serta berbagai wacana amandemen UUD 1945 dalam beberapa waktu belakangan. Metode penelitian yang digunakan dalam penelitian ini, yaitu yuridis normatif dengan pendekatan studi kepustakaan. Hasil penelitian ini menunjukan bahwa sebagian besar prinsip konstitusionalisme sudah tertuang dalam UUD 1945 hasil amandemen, namun belum sepenuhnya sempurna. Sedangkan, wacana amandemen konstitusi yang mengemuka di publik belakangan ini secara seimbang mengarah pada penguatan dan pelemahan prinsip konstitusionalisme.

As social beings, people frequently run into intellectual property issues in their relationships. God created humans as complex beings with a variety of needs in order to function. The ingredients required by humans to sustain physiological and psychological equilibrium, which attempts to maintain life and health, are also basic human requirements. There are a number of things that might lead to copyright infringement in Indonesia, from lax government regulations to a lack of public understanding of the value of copyright and the protection of intellectual property rights. However, because of the fair use doctrine, copyright is not entirely controlled by the inventor or copyright holders. The Fair Use Limit Concept in Law Number 28 of 2014 Concerning Copyright is the formulation of the problem in this study, which seeks to determine how far the Fair Use Limit Concept is in Law Number 28 of 2014 Concerning Copyright, the methodology utilized in This study employs a type of normative research that involves reading reviews of secondary sources of information. This study also takes into account and examines copyright laws and regulations. The study's findings demonstrate that Indonesia's fair use laws are appropriately evaluated by the presence of the author's name or the use's noncommercial intent. In Indonesia, fair use laws give more people the chance to work and develop their creativity by utilizing the works of others. This is consistent with the essence of copyright, which requires that individuals produce specific works, which in this instance can be accomplished through the modification of other individuals' copyrighted works.

Sexual violence against children is a social disaster that presents a serious problem that worries people in Indonesia. Sexual violence is a form of dangerous behavior that is carried out unilaterally and unintentionally by the victim through language, writing, symbols, gestures, or actions that have sexual meaning. Sexual violence against children can be in the form of cruelty to animals, rape, obscenity, and incest. Ideally, legal protection for child victims of various forms of sexual violence must be optimally achieved. According to the 1945 Constitution, the state has a legal obligation to guarantee children's rights to survival, growth, development and protection from violence and discrimination. The problem studied in this research is how legal protection is in recovering children from victims of sexual violence. This study uses descriptive-analytic legal research, the purpose of which is to provide an overview of the problem by processing and analyzing data to then obtain materials and problem-solving proposals. The conclusion of this study shows that legal protection in the recovery of children from sexual abuse is very important to ensure that children who experience sexual abuse get their rights and get the support and care they need to recover from this traumatic experience.

Authors:   , Peemdechachai Nichkan
Published: April 2023

This study analyzed an automated system of container operations at Laem Chabang Port, Thailand. Due to the rapid growth in demand at the port, the throughput volume cannot reach the requirement, has difficulty in unskilled worker recruitment, working hours are limited, and has limitation on the terminal area. Therefore, an automated system is planned to replace the conventional container operations; this will also support the Port Authority of Thailand's encouragement of using automation technology. Along with the increasing the level of port development and enhancement of the container terminal port to be competitive in the world trade arena by developing and managing infrastructure and facilities to meet world-class standards. This study assumes an automatic system for container handling through the combination of machines, i.e., a semi-automated ship-to-shore gantry crane, an automated rubber-tired gantry crane, and an automated guided vehicle for the container movement. The specification of machines was obtained from the existing available technology in the marketplace. The data collected from the literature performance evaluation of container port outputs is simulated using ARENA software. The analysis showed that the automated system could improve operations in many aspects such as berth occupancy, ship waiting time, ship turnaround time, machine utilization, and resulting in much better container throughputs. Lastly, this paper summarizes the port's main advantages and challenges if the automated system is implemented.
Lagrangian relaxation method for integrated vehicles and drones routing model
Authors:   , Charoenwut Perawit
Published: April 2023

Nowadays, e-commerce increases parcel transportation demand year by year. Many companies are seeking the way to improve performance of delivery service and cost-efficiency. One among many solutions is using a drone attached with a truck for the last mile delivery. A drone can be launched from either depot or truck and returned to the depot or wait for the truck to take them back from the docking station around the delivery area. The vehicle routing problem with drones considers truck- and drone-route simultaneously. It is an enormous problem that cannot be solved by a normal linear programming method. This research proposes the Lagrangian relaxation technique, in conjunction with the Branch-and-Price technique, to estimate the lower bound of the solution in each iteration of the Branch-and-Price. The lower bound from the Lagrangian relaxation is tighter than the solution from the Column generation which can improve the total solution time. The bound use in Branch-and-Price as a fathom condition, these help the search tree not to explore unnecessary nodes. The computational experiment includes randomly generated instances and real-world instances. Moreover, the operation cost of truck-based and truck-drone-based are compared to point out the benefit of using drones.
Sulfonated polyetheretherketone/polyvinylidene fluoride blend polymeric cation exchange membrane as separator in zinc-iodine flow batteries
Authors:   , Pusanasuwanasri Pimpen
Published: April 2023

Zinc-iodine flow batteries (ZIFBs) are very appealing owing to their abundance of active materials, low cost, high safety and environmental friendliness. The cation exchange membrane (CEM) separator contributes a significant part to the cost and determines battery performance. Sulfonated poly (ether ether ketone) (SPEEK) is a promising candidate as a CEM separator. The ionic conductivity of SPEEK CEM can be tuned by adjusting a degree of sulfonation (DS), but the mechanical property of CEM could be deteriorated. Blending poly (vinylidene fluoride) (PVDF) with SPEEK can improve the mechanical strength of SPEEK membrane. Therefore, this study examined the effect of PVDF contents (5, 10, 15 and 20 wt.%) on the physicochemical properties of SPEEK/PVDF membranes for using as CEMs in ZIFBs. ZIFBs were fabricated as static H cell and flowing stack cell configuration. Moderate DS of SPEEK (53%) was used in this study. The physicochemical properties, which are surface morphology, cross section, water uptake, electrolyte uptake, swelling ratio, ionic conductivity and iodine species crossover preventability, of the synthesized membranes and battery performances were investigated and compared with commercial Nafion115 membrane. It was found that the SPEEK, blend membrane with 5 wt.% PVDF (denoted as SP 5) and Nafion115 membrane were dense, uniform and homogeneous. The SPEEK and SP 5 membranes are further investigated for their good physicochemical properties and good battery performances. ZIFBs using SPEEK/PVDF membranes were able to be operated over 700 cycles indicating long cycle life performance. ZIFB with SP 5 membrane showed higher energy efficiency compared with Nafion115 membrane (77.52% vs. 69.71%). In addition, ZIFB with SP 5 membrane also showed significantly better stability than Nafion115 membrane corresponding to the mechanical property of membranes. Furthermore, the cost of SP 5 membrane is lower than Nafion115 membrane by around 2.5 times. Due to its low cost and other good features, the SPEEK based membranes prove to have the quality for use as CEM separator in ZIFBs.
