Aims: This study examined the impact of early child care and development (ECCD) education on psychomotor, affective and cognitive domains of learning in elementary school students. Study Design:  This descriptive study employed qualitative and quantitative methods. Place and Duration of Study: The study was conducted in five schools under Chukha Dzongkhag for a period of one year (2019-2020).  Sample: This study involved a survey of teachers and observation of students in 5 schools of Chhukha district. Seventy three teachers were selected to fill out the questionnaire using homogenous sampling technique and 6 students were selected as participants for observation using simple random sampling technique. Methodology: Quantitative data were gathered through questionnaires, and documents and artifacts while qualitative data were gathered through observation for this descriptive study. The data collected from questionnaire, document and artifact and observation were triangulated to facilitate validation of data through cross verification and strengthen the findings of the study. Results: The results indicated positive impact of ECCD on elementary school students’ academic performance. In particular, the analysis revealed that ECCD education has the highest level of impact on students’ psychomotor performance, followed by affective and cognitive performance. Conclusion: In view of these findings, the researchers recommend the ECCD education programme developers and instructors to look for a balanced curriculum that ensure equal development of cognitive, affective, and psychomotor domains of learning.

Freshwater plants play a paramount role in an aquatic ecosystem. However, only limited studies have been carried out on freshwater plants. Therefore, the study aimed to assess the diversity of freshwater plants in different freshwater bodies of Punakha District, the correlation of freshwater plant species with the environmental variables, and the local community difference in freshwater plant use knowledge in Punakha district. A total of 20 water bodies were selected using a stratified sampling method. Area-based surveys were employed to assess the plant species from a total of 80 plots, each with the quadrat of 5 m x 5 m. Environmental variables such as altitude, water depth, water velocity, temperature, precipitation and evapotranspiration were measured. The study recorded a total of 72 freshwater plant species distributed among 57 genera and 37 families. Shannon-Weiner diversity index revealed high diversity of freshwater plants from ponds (H’ = 3.3) followed by ditches (H’ = 3.16), streams (H’ = 3.07) and lakes (H’ = 2.83). The study revealed the decrease of freshwater plant species with an increase in the water velocity, depth and altitude. There was a significant association between respondents’ freshwater plant use knowledge with gender (x2 (1) = 6.04, p = .014), age (x2 (1) = 13.21, p = .000) and education level (x2 (1) = 4.53, p = .003). Females and illiterate respondents with aged 31 years old and above had more knowledge on freshwater plant use compared to males and educated respondents with aged 30 years old and below.

This project presents a comparative study between power generation using piezoelectric transducers available in the literature and the proposed model design. The parallel and series-connected piezoelectric transducers arrangement in this project, when subjected to mechanical stress (footsteps), generates an electric charge. The power generated from piezoelectric transducers will be given as input to bridge rectifier and chopper for conversion to dc quantity and its amplification respectively. This energy will be stored in a Li-ion battery. The paper mainly highlights aspects of improvement of power generation by optimizing circuit design and adapting output enhancement and amplification. Comparative analysis of power generated from predecessor circuit designs and output voltage obtained from current circuit design is validated and presented
