Abstract:

Perceptions of the environment that young children acquire in their early childhood function as a base for their holistic development. The studies convey that there is a convincing positive relationship between childhood experiences in nature and the formation of pro-environment beliefs and lifestyles later in life. Literature also depicts if children do not develop a sense of respect and caring for the environment during their early years, they are at risk of never developing such attitudes later in life. Hence, there is an urgency to assess young children's attitudes pertaining to the environment to find out whether they hold favorable attitudes towards it. However, there is a lacuna of research on this topic in local as well as global context. 
The present study explores the preschool children's attitudes pertaining to the environment using a two point pictorial rating scale (12 statements in 6 pairs). Participants were 34 preschool children (M = 4.09; S.D = .588), 13 boys (M = 3.91; S.D = .539) and 21 girls (M = 4.19; S.D = .602), from Colombo, Sri Lanka. The research was conducted, adhering to the ethical standards of test administration for young children. After listening to their preschool teacher instruction the children were requested to put stickers against the appropriate picture which indicated their preference. Results conveyed that majority of the children displayed pro-environmental attitudes (M = 5.412; S.D = 0.821).

Abstract:

The present research work is promoted by the increasing demand of the data belonging to the terrestrial γ-ray activities into the soil of cyclone (Aila) affected of two upazilas at Khulna and Bagerhat districts of Bangladesh. For measurements of naturally occurring radioactivity and artificial fall out, in the present work a total of 23 soil samples were collected. The samples were then prepared and irradiated for activity measurements using HPGe detecting system. The average concentration of radioactivity in soil samples for 238U is 35.9 ± 3.05 Bq Kg-1,  232Th  is 61.71 ± 3.30 Bq Kg-1  and 40K is 489.49 ± 35.76 Bq Kg-1, are nearly the world wide average concentration value. The annual effective dose was measured 29 to 168 µSv which is also comparable with worldwide average. External and internal hazard index does not excided the recommended limit. No artificial fall out detected in these study areas.


Abstract:

Perception of open/semi-open, semi-private/semi-public spaces in the housing areas (described as ‘grey matters’ by the authors) have shifted from being only common areas to social interaction venues. Diversity in demographic patterns and daily living culture amongst educated individuals of 23-37 ages reflect such changes. This paper displays the results of the first three steps out of 6 that explore the problem through preliminary observation, quantitative data and accompanying qualitative data. The first step refers to field notes, photographic documents. The questionnaires, in step 2 and semi-open in-depth interviews conducted with the same 49 participants, step 3. The methodology bases on grounded theory by which the inquiry is extended through the data. In-depth interviews accompanied by the surveys are the core tactic, since generic surveys would neglect the unique grey matters typologies. Smaller number of surveys is superposed with the qualitative findings. The early findings reflect the demographic issues as marital status, sub-age groups, having children and daily living culture indicators as background, work-patterns in relation to urban characteristics, dwelling type and grey matters’ features. The central axe of Istanbul is focused via underground lines, due to the literature on young adults’ locational preferences. The study puts forward a rather new research area in the housing studies, because the young residents’ housing intensities are examined through social interaction in the vicinity of their dwellings. Perception, usage and supportive role in social interaction in the grey matters are thus explored.

Abstract:

One of the most common day to day challenges that a knitting industry faces is to determine the appropriate count and stitch length to meet the finished GSM of a fabric. This paper puts an attempt to present an equation for count and GSM for plain single jersey using the value of fabric constant which can surely ease this regular calculation process and can be used as a base to develop new software for industrial application.


Abstract:

The aim of this survey is to investigate whether the Electromagnetic Fields (EMF) emitted from various lab equipment and air conditioners and switch boards affect the students, faculties and employees. There is a standard threshold value recommended by WHO for both electric and magnetic fields. Electro-Magnetic Field also named Non Ionizing Radiation is emitted from high power transmission lines, computer monitor/video display unit, radio waves of different frequencies, telecommunication, satellite, radar etc. which causes health hazards to living system and environment. There has not been much study performed in Bangladesh. The data were collected from various Electronics and Telecommunication Engineering (ETE) department labs at Daffodil International University in Dhaka, Bangladesh. Threshold values of Magnetic fields are measured for various lab equipment, air conditioners and switchboards. The maximum value of the magnetic field results showed that in many cases the magnetic field radiated from the different sources are greater than the threshold limit, which are the main point of our findings.


Abstract:

This study aims to investigate the trend and impact of Chaldal.com on the competitive business environment of Bangladesh. This study discloses how this rising online grocery business is growing and it’s strong impact on the business environment of a developing country. The modern view of doing business involves with rapidly changing technologies, workforce redesigning and diverse global business operation. Online and offline were once two very separate worlds. But with the rise of e-commerce and in particular mobile e-commerce, the distinction between online and offline is blurring rapidly.One of the internet’s early effects was to foster a much greater proliferation of specialty retailers than ever earlier, vendors with a unique point of view but not necessarily a need for a tremendous amount of floor space. One of the biggest inclinations is to integrate strong national or international brands with stores or restaurants with a strong local vibe or presence, so that consumers feel that they have the best of everything available to them in one place. So Online shopping is a growing trend in  all over the world including developing country and perhaps in response to the private nature of online shopping, the public experience of shopping and for its convenience nature  has made it  very popular in developing countries. Here a questionnaire survey was conducted to identify the trend and growing popularity of Chaldal.com in national economy and also how it is influencing the current business environment.

Abstract:

The purpose of the present study was to explore self esteem and attitude towards school of rural and urban high school students. In order to achieve this end, 120 students from classes 8-10 of rural and urban schools were selected and their age range was from 12 to 15 years. Purposive Sampling technique was used to select the participants of the present study. Result shows that students of  urban high school has high score in self-esteem than rural high school and mean scores of attitude towards school of rural and urban high school students are M= 96.62 and M=104.50.This indicates that students of  urban high school has high score in attitude towards school than rural high school. An independent-samples t-test was used to assess difference between self-esteem and attitude towards school of rural and urban high school students. There was no significantly deference in the scores obtained for self esteem of male (M=26.20, SD=5.31) and females (M=29.45, SD= 5.79) t (120) = -3.596, p = .778).There was no significantly deference in the scores obtained for attitude towards school of male (M=104.18, SD=14.50) and females (M=96.93, SD= 19.34), t (120) = -3.596, p = .778). A Pearson product-moment correlation coefficient was used to investigate the relationship between self-esteem, attitude towards school, rural and urban high school’s students. Some of the significant finding of the present research could not be justified by the findings of other research. Therefore it is suggested that further research is earned on replicating the present one.

Abstract:

A mobile in our hand has the power to connect us with anyone from around the world, however far-off they may be. It has revolutionised how we connect to our near and dear ones and also those with whom ties would have been severed otherwise because of distance. Today teens prefer text messaging over face-to-face conversation. But as the technology ramps up, our emotional lives ramp down because in liking, commenting, posting and internet interactions, the purpose sitting right next to us are the ones whom we ignore the most. The present study argues that we may be free to operate from anywhere but we are also prone to being lonely everywhere. The study also emphasizes the rationale of some disconnect from digital communication to nurture our human spirit.

Abstract:

The crude methanol extracts of whole plant of Wedelia chinensis Osbeck. Merr., stem bark of Mimosa diplotricha Sauvalle. and leaves of Bauhinia purpurea Roxb. as well as their hexane, carbon tetrachloride, chloroform and aqueous soluble partitionates were subjected to screening for thrombolytic activity. The extractives of W. chinensis demonstrated varying extent of clot lysis activities within the range of 4.11 % to 44.24 %. The highest thrombolytic activity was demonstrated by the carbon tetrachloride soluble fraction (44.24±0.48 %) when compared with the standard thrombolytic drug streptokinase (66.77 %). Among the extractives of M. diplotricha and B. malabarica  the carbon tetrachloride soluble fraction (19.76±0.88 % clot lysis) and the aqueous soluble fraction (25.83±0.88 %) revealed the highest thrombolytic activities, respectively.


Abstract:

Mass attenuation coefficients of some important X-ray imaging photoconductor materials namely Mercuric Iodide, Lead Oxide, Lead Iodide and Cadmium Zinc Tellurium are simulated for different photon interaction energies. The order of dependence of mass attenuation coefficient on photon interaction energy is determined and corresponding empirical models were developed for each compound. The order of dependence and hence the empirical formula is found to be different in two different energy ranges. In the energy range of 1KeV-110KeV, the order of dependence of mass attenuation coefficient on photon interaction energy is found to be approximately -1.6 and in the energy range of 110KeV-20MeV, the order of dependence is found to be approximately -2.45 for all the compounds.
