Peer interactions are important in preschool years because they lead to positive social and emotional development in children. Children, who can interact successfully with their peers, are more popular, have stronger friendships, and are included more often in classroom activities. Play takes a significant mean of promoting peer interaction in children. However, the attention given to such opportunities are declining at present due to increasing demands for more written exercises. Thus the study attempted to promote peer interactions among preschool children through play. The objectives were to examine how peer interactions are promoted through play and the role of the teacher in that process. The single case study design was employed. The sample comprised with a group of 12 children selected purposively from 4-5 year olds in a preschool located in Nawala area, Colombo District. A socio dramatic play intervention was implemented for 3 weeks collaboratively with the preschool teacher. The data gathered through the observation; interview and reflective journal were analysed based on descriptive analysis method under several sub themes. The data revealed that the majority of children were able to improve their peer interactions in the play intervention. Significant improvements in the abilities to cooperate with children recognise needs of peers and responds positively, comfort friends and share ideas and objects with peers were identified. Boys showed better interactions than girls. The strategies such as giving prompts or cues, constructive feedback and giving play ideas used by the teacher created many opportunities for children to improve peer interactions in the play intervention. Therefore, the study concluded that more opportunities are created through socio-dramatic play intervention to improve better peer interactions in preschool children though these play activities are not encouraged in the preschool and the nature of the teacher's role is identified. Lack of generalisability was a limitation in the study. Thus the study recommends providing more emphasis on giving more opportunities to peer interactions through play in the preschool classroom by giving more guidance and training to teachers.

This review proposes a system of classification of queues in the Banking sectors. The goal is to provide sufficient information to an analyzer who is interested in using queueing theory to model an effective queue management process. Customer satisfaction is a concern to service industries as customers expect to get their service promptly when they arrive. Demand for service is highly variable, and it depends on customer's satisfaction. For a service industry like a bank, there is a need for efficient bank Teller scheduling system that takes into account recognizing various customer expectations. This research study involves as to how a bank could provide value added customer service by reducing customer-waiting time to the maximum possible standard. The model takes into account real time system behaviour including changing customer arrival rates throughout the day and customer service manner. This study is centered on the single channel waiting line systems with poisson arrivals and exponential service times in Bank of Ceylon, City office, Bank of Ceylon Kuliyapitiya and Bank of Ceylon Bingiriya. Banking activities and behavior of these three branches are completely different. They represent stages of customer-flow management processes. Waiting systems are stochastic mathematical models and they represent the describing base of the waiting phenomena, services processes, and prioritization among others. Mathematical models of queuing theory present interest in modelling, designing, and analysing information networks.

Now they have a chance to participate in a cash economy being able to send children to school, to pay utility bills and, importantly, to feel better that they have control over their lives instead of occupying in a full time job locally or abroad. This has also created a social effect. Women in business are not only able to take care of financial position of the family but also they have quicker access to family due on any reason than a working woman. However, it has not been observed how effectively women run businesses to contribute to their family and to the economy of the country. It is common that the effective management of a small business will lead to expand the business into medium and large scale in future. This study basically aims at the progress of women in small business and how effectively they run the business towards goals in future expansion. The research method chosen and best suited to this study is descriptive quantitative research. The proposed method for data collection is close-ended questionnaire to maintain accurate accounts of information given. The researcher has used 50 registered women in small business that fitted with the outlined criteria chosen through simple random sampling. The researcher concludes the study by observing the importance of creating awareness of the need for women to invest in small businesses and financial institution to introduce new financial mechanisms to develop women in businesses.

Sewing Machine Operators (SMOs) can be considered as the key personnel in the apparel industry. One of the major challenges faced by the apparel industry is the retention of skilled SMOs through enhancing their job satisfaction. Therefore, the employers are keen on identifying the level of satisfaction of the SMOs about the job and on taking necessary actions to manage the factors which are associated with job satisfaction. This study focused on the job satisfaction of the SMOs employed in a particular manufacturing division of a reputed apparel company in Sri Lanka. The data were gathered through self-administered questionnaires. In the sample, most of the SMOs are on their first employment. Majority of them represent the age category 20-29. Almost half of them are married and among them nearly 50% of SMOs have children younger than six years. Overall job satisfaction of the SMOs are in a higher state where more than 75% of SMOs indicated satisfied in job satisfaction scale. The food and the number of uniforms provided are the most dissatisfactory aspects. Further, the univariate analysis revealed that SMOs working for more than five years have a higher satisfaction level. The SMOs in the age category 30-34 are highly satisfied and greater than 34 are less satisfied. Married SMOs also display a higher job satisfaction level. Discrete Proportional Hazard model was fitted to model the job satisfaction of SMOs. Place of accommodation, service level, facilitative working environment, effective working relationships and pressure from the family were significant at 5% level. The Deviance test, Pearson chi square test and Parallel lines test concluded the goodness of fit of the model. Odds ratios revealed that the SMOs residing at their own houses are more satisfied than the SMOs residing outside.
