East African Community employment is dominated by agriculture, which motivated this study. Generally, this study pursued an analysis of openness of trade and women employment in selected EAC countries. The study examined the impact of openness of trade on both agriculture and service sector employment of women. In particular, the purpose of this study was to investigate how trade opening affects the employment of women in the agricultural sector in some EAC counties. and explore how trade opening affects the employment of women in the service sector in some counties of the EAC. The results show that trade opening had a negative impact on women’s employment in the agricultural sector, but had a positive impact on the service sector. This implies trade openness has shifted female employment pattern from agriculture to services sector. The study was conducted using a longitudinal panel design. The study concludes that efforts should be made to retain female workers in agriculture by retraining them, while promoting their employment through trade facilitation services and support with marketing. Concerning agricultural sector, the study recommends retraining of female workers in the agricultural sector to improve their skills set as well as providing credit to enable them move from lower cadre employment in agriculture.

Batch-type ceramic kilning is an energy-intensive process whose primary expense is fuel consumption. This work demonstrates the incorporation of the Internet of Things (IoT) into an existing ceramic furnace to achieve more precise temperature profile control and lower fuel consumption. A long-term analysis of the kiln owner’s continuous utilization and adoption of the technology was performed. A total of 20 kilns in northern Thailand’s factories have been selected for implementation. The owner of the facility, who is also the operator of the kiln, can monitor and modify the kiln’s settings online using near-real-time information. The sensors, wireless connection devices, a cloud server, and mobile applications that comprise the IoT are tailored to achieve these goals. The kiln has been outfitted with sensors such as a gas flow meter, a gas pressure sensor, and kilning room temperature, wall temperature, and ambient temperature sensors. Using the narrowband-IoT (NB-IoT) network provided by a local communication company, continuous monitoring data, consisting of 8 to 10 hours of kilning time and 2-3 batches per week, have been sent to a cloud server every minute. On a smartphone, online information with alerts can be displayed. The study’s outcomes indicate that a kiln operator can consistently control the kiln from batch to batch, resulting in minimal fuel consumption. Compared to before the installation of IoT, data collected over three years indicates a 5.6% improvement in energy efficiency. Total annual petroleum savings amount to $59,787 for the 20 kilns. The straightforward repayment period is 4.7 years. According to a field investigation, IoT technology has an approval rating of nearly 9 out of 10.

Stuxnet is a highly customized malware developed to destroy centrifuges used in the Iranian nuclear program through SCADA systems. It infects a computer through a USB drive, making it effective for targeting air-gapped networks. Stuxnet is larger and more complex than an equivalent worm; it is created in several different programming languages, and some components are encrypted. The malware utilizes four unprecedented zero-day vulnerability attacks that exploit application security vulnerabilities before developers become aware of the vulnerability. Additionally, it employs advanced rootkit technology to conceal itself from users and antimalware software on both Windows and the control computer it targets. To strengthen cybersecurity, this study implemented and configured a combination of firewalls and intrusion detection systems (IDS) to enhance security against the Stuxnet malware. By integrating these security measures, the aim was to establish a robust defense against the sophisticated attack methods employed by Stuxnet. It is essential to continuously update and adapt these security measures as the threat landscape evolves. By remaining vigilant and proactive, organizations can effectively safeguard their systems from sophisticated threats like Stuxnet, bolstering their cybersecurity defenses.

The paper discusses the concept of employee motivation in the workplace and its importance for organizational success. It highlights the gap in literature regarding the most effective ways to motivate employees, which mainly focuses on individual factors such as personality traits and motivational theories. The paper aims to explore the impact of both individual and organizational factors on employee motivation and to determine the most effective ways to motivate employees. The existing academic research on employee motivation is plagued by contradictions and inconsistencies, particularly regarding the emphasis on individual factors as the primary drivers of motivation and ignoring the impact of organizational factors. The paper argues for a more holistic approach to employee motivation that considers both individual and organizational factors.

Our study is intended to look into the association between accounting information and market stock price for the Non-Banking Financial Institutions (NBFI) listed on the Dhaka Stock Exchange. For this study purpose, we take 12 Non-Banking Financial Institutions (NBFI) out of 23 listed companies. For this study purpose, Ohlson ‘s (1995) basic valuation model has been used. Multiple and simple linear regression technology is used to ascertain the explanatory power of independent variables on the dependent variable. Data analysis is carried out in IBM SPSS v. 20 software. Estimated regression coefficients and adjusted R2 of accounting information are tested in this model. Here we take Earning per share (EPS), Return on Asset (ROA), Return on Equity (ROE), and Book Value (BV) per share are independent variables and Market share price as the dependent variable. Findings from this study indicate that all the independent variables have the influencing power in forecasting the share prices. From the individual effect analysis, it is clear that EPS and ROA are the most influential variables for determining the stock price for this selected industry. Thus, among the four independent variables EPS and ROA are considered the most value-relevant accounting information for equity investors.

Given the fact that the change of internal and external environment, iron and steel enterprises emphasize the management of technical staff through authorized leadership and the realization of innovative behavior and performance through the hard work of technical staff. Because of its own characteristics and advantages, technical staff has become the core force of innovation in iron and steel enterprises, which not only attracted the attention of iron and steel enterprise managers, but also attracts more and more attention from theoretical researchers. Among them, it has become an important topic and thus the purpose of this paper to study the influence of leadership style on innovative behavior and innovative performance of skilled employees. The implications of this study show that an authorized leadership style can meet the needs of technical employees for self-management, eager to be respected and engaging in innovative activities in a relatively relaxed environment. However, in the existing literature, there is not enough research on the intermediate mechanism of how authorized leadership affects the innovative behavior and performance of technical employees, especially from the perspective of psychological factors such as trust, emotion and psychological capital of technical employees. The quantitative design shows that the intermediary mechanism between technical staff’s innovative behavior and innovative performance needs to be further studied to reveal its internal law.

The goal of this study was to identify and analyze the factors that influence the quality of internal audits in a sample of Bangladeshi banks. The study used a combination of qualitative and quantitative research methods and included a sample of banks chosen based on the size and representation of different regions in the country. Data was collected through interviews with internal auditors, management, and regulators, as well as analysis of internal audit reports and other relevant documents. The findings of the study showed that several factors contribute to the quality of internal audits in Bangladesh’s banking sector, including the independence and objectivity of the internal audit function, the expertise and qualifications of internal auditors, the adequacy of resources and support, and the effectiveness of communication and reporting. The study also identified areas for improvement, including the need for greater standardization and consistency in internal audit practices and the importance of aligning internal audit activities with the organization’s risk profile. These findings have implications for internal auditors, management, regulators, and other stakeholders in the banking industry, and offer recommendations for improving the quality of internal audits in Bangladesh.

Bangladesh has made significant progress in reducing child malnutrition over the years. However, malnutrition remains a considerable challenge in the country, particularly among children under the age of five years. This study aimed to determine the risk factors involved with child malnutrition (i.e. underweight, stunting and wasting) among children under five in Bangladesh. We examined the potential risk factors of child underweight, stunting and wasting using data based on multiple indicators cluster survey (MICS) conducted in Bangladesh in 2019. The data included 18,696 children (under the age of five years) respectively from 64,400 households. Binary logistic regression models were used to evaluate the potential risk factors associated with malnutrition in children. About 27% of children under age five are stunted (short for their age), 10% are wasted (thin for their height), and 22% are underweight in Bangladesh. The most critical risk factors of child malnutrition in Bangladesh were the mother’s education, mother’s age at birth, place of residence and wealth quantile.

This study adopted development of a shaking table to simulate real earthquake loadings in the laboratory. It is a platform excited with a type of mechanical loading to provide periodic or random motions. Currently, it is the only experimental method to simulate different types of motion such as earthquakes, ground motions, and sine sweeps directly. In order to perform dynamic testing to simulate seismic loading, a large, effective, and practical shaking table was designed and manufactured in this study. The developed shaking table is capable to move in horizontal and vertical direction forward and backward and combination of those. Several researches utilized shaking tables in geotechnical engineering under seismic loads to evaluate miscellaneous parameters. Although these researches that developed excellent shaking tables, there is a high demand to design and manufacturing a shaking table capable to simulate the seismic load and its effects on the buildings. To attain this objective, this study aims to develop a novel shaking table that can simulate the manner of the real earthquake. The shaking table proposed in this study capable to mimic an earthquake that starts from a high energy then the energy decreases gradually until reach the zero. In addition, the proposed shaking table can implement simulated earthquake for time similar to that occurs in the nature. Therefore, this study can fill the research gap in this domain. The proposed shaking table work was verified and validated by testing based on repeated operating.
