A Perspective Human Resource Development Model for the Nuclear Power Plant of Bangladesh
(Research and Development Wing, MIST, 2026-06-30) Md. Nahid Hasan; Md. Toufikul Haque; Md. Simul Hasan Talukder
The successful and peaceful use of nuclear power requires a competent, sustainable human resource plan. The International Atomic Energy Agency (IAEA) identifies Human Resource Development (HRD) as a critical milestone for countries embarking on nuclear power programs. As a newcomer to the nuclear industry, Bangladesh faces significant challenges in developing a skilled workforce to ensure the safe operation and long-term sustainability of nuclear power plants. Despite ongoing technical and infrastructural development, a structured and context-specific HRD framework for the nuclear sector remains insufficiently addressed. This study proposes a comprehensive human resource development model tailored to the needs of Bangladesh’s nuclear power program. The model provides a strategic roadmap for capacity building by defining workforce requirements, identifying key stakeholder groups, outlining education and training pathways, addressing institutional and policy challenges, and incorporating national policies alongside international cooperation mechanisms. Particular emphasis is placed on aligning national initiatives with IAEA guidelines to ensure compliance with global safety and security standards. The proposed framework aims to support the development of a highly skilled and sustainable professional workforce capable of ensuring the safe, secure, and efficient operation of nuclear facilities in Bangladesh. By strengthening national capacity in nuclear human resources, the model contributes to long-term energy security, regulatory effectiveness, and sustainable socioeconomic development.

Neutronic instruments are commonly used by reactor operators to monitor reactor power; however, thermal methods remain the standard for calibrating reactor power during routine operation. This paper presents the results of thermal power calibration for the 3 MW TRIGA MARK II research reactor, comparing two heat transfer approaches: the calorimetric method and the heat balance method. Calibration data were validated under forced convection cooling conditions. The calorimetric method was applied at a low power level of 100 kW, yielding a thermal power measurement of 98 kW, closely matching the reactor’s design specifications. The heat balance method was employed at higher power levels of 1 MW, 1.5 MW, and 2 MW, based on measurements of inlet and outlet coolant temperatures and water flow rate in the primary cooling loop. The thermal power values obtained were 831.5 kW, 1293.5 kW, and 1755.4 kW, respectively. Deviations were mainly attributed to limitations in analog instrumentation, fluctuations in mass flow rate, and measurement uncertainties. Comparison of the two methods indicated that the calorimetric method provided more accurate and reliable power calibrations, whereas the heat balance method exhibited greater discrepancies. Overall, the findings underscore the suitability of the calorimetric method for precise thermal power calibration of TRIGA MARK II reactors.
Assessing Child-Friendly Space (CFS) Standards in Dhaka’s Government Primary Schools: A Case Study Approach
(Research and Development Wing, MIST, 2026-06-30) Zayed Kazi; Iqra Binte Zamil
In Bangladesh, compulsory primary education covers classes of 1 to 5, administered by the Directorate of Primary Education (DPE). In Dhaka city, it includes 342 schools under 12 educational zones. Due to multilateral shortcomings of budget policy, governance and emerging population, these schools are fighting to provide proper infrastructure to students. Inadequate classrooms and playgrounds, poor light ventilations, unhygienic toilets, lack of multipurpose activity spaces and poor building quality are the significant shortcomings. The objective of this study is to identify the inadequacy of physical environment design of government primary schools based on Dhaka. Relying the child friendly school (CFS) model from different organizations this study attempts to scrutiny the indoor and outdoor quality of the built environment as well. Adopting descriptive case study approach, this qualitative study compared between the CFS standards and primary schools to cross examine the presence of the CFS attributes. As the schools are designed in prototype designs, a randomly selected school was used for data collection through a combination of direct observational methods and semi-structured stakeholder interviews, ensuring a comprehensive dataset. The quantitative data was solely used to assess the attributes of the CFS model. The findings show that the physical facilities of these schools do not satisfy the CFS standards. After a meticulous observation, the researcher found that the schools have acute inefficient sanitation facility. The researcher concludes that proper building maintenances, adequate budget allocation, child inclusive built form and proper communication between stakeholders are much needed to elevate the quality of the physical environment.
Comparative Dosimetric Analysis of Tandem-Ovoid and Tandem-Ring Brachytherapy Applicators in Cervical Cancer

Brachytherapy plays a vital role in the treatment of locally advanced cervical cancer by delivering high radiation doses directly to the tumor while minimizing exposure to surrounding healthy tissues. This retrospective study compared the dosimetric performance of tandem–ovoid (T&O) and tandem–ring (T&R) intracavitary brachytherapy applicators in 60 cervical cancer patients treated at CMH Cancer Center, Dhaka. Patients were divided into two groups according to applicator type, with 30 patients in each arm. Dosimetric parameters including HR-CTV 90% coverage, rectal dose, and bladder dose were analyzed. The average HR-CTV 90% coverage was 106.91% for the tandem–ovoid applicator and 100.43% for the tandem–ring applicator. The average rectal dose was lower in the tandem–ring applicator (4.93 Gy) compared to the tandem–ovoid applicator (5.57 Gy). However, the bladder dose was slightly higher in the tandem–ring applicator (5.31 Gy) than in the tandem–ovoid applicator (5.20 Gy). The findings indicate that both applicators provide clinically acceptable dose distribution, although tandem–ovoid demonstrated comparatively better target coverage while tandem–ring showed improved rectal dose sparing. Applicator selection should therefore be individualized according to treatment priorities and patient anatomy.
Next-Gen ECG Technology: Dual Lead System Empowered with IoT Connectivity for Comprehensive Cardiac Monitoring

The need for Internet of Things (IoT)- oriented, cost-effective Electrocardiogram (ECG) devices that can remotely measure and transmit ECG signals is becoming increasingly apparent. While standard 12-lead ECG monitoring is effective, its bulky and time-consuming nature poses challenges for remote and continuous monitoring. For developing a cost-effective ECG system, Einthoven's six-lead ECGs are effective but need assessment in real-world conditions. Addressing this gap, this study explores performance evaluation of the dual-lead-to-6-lead ECG monitoring method under 50 Hz noise, electrode reuse, and proximal vs. distal placement. Our system incorporates an ECG circuit that records lead I and lead II data and calculates the 6 leads mathematically. A digital notch filter is applied to the data to enhance signal clarity. The study also includes an arrhythmia-detection component that uses the Pan-Tompkins algorithm to identify abnormal cardiac rhythms promptly. A comprehensive performance analysis of 11 healthy patients was conducted. The reference ECG signals were simultaneously recorded using a BIOPAC MP36 data-acquisition system, with Pearson correlation coefficients ranging from 0.81 to 0.89, with the highest in Lead II. Bland-Altman analysis for R-R interval and Heart rate showed average biases of 11.66 and 0.35, respectively. All data points for both R-R interval and heart rate fell within the ±10% acceptability limits. The proposed technology has potential for telemedicine services and remote patient management, offering an effective solution for continuous, remote ECG monitoring.
