A Study on the Significance of Transport Sector on the Garments Industry in Dhaka City
(University of Dhaka, 2019-10-10) Nahar, Lutfun
Garment industry has become the single largest source of foreign currency earning of Bangladesh only within a few decades. It has been contributing to the socio-economy of the country including expediting the wheel of economy, increasing trade volume, creating labour market for around four million people while around 80 percent of them are women. Bangladesh is the second largest exporter of RMG expanding its market to more than 100 countries. RMG industries have overcome several obstacles it encountered time to time. However, due to lack modernized infrastructure particularly in terms of communication and transport system it undergoes some challenges. This study has been undertaken to find out how transport sector is contributing to the development of RMG sector and expediting export and import of RMG as well as what are the challenges still exist in transport sector which can be addressed. In line with this, this study has targeted to identify the existing transport modes, the distribution pattern of raw material and finished goods, the costs the owners have to incur. Garment industries in Dhaka city have been identified for survey. In addition, buyers, buying organizations and other related stakeholders have also been consulted. The transport sector has been indeed one of the major factors for developing the garment industry. It affects the lead time in large extent. The exporters have to maintain the lead time- time from receiving order to shipment. In this case transport is essentially the major factor for movement of raw materials and supply of finished goods to the sea port within the agreed time. In addition, transport sector largely contributes to supply chain management. This study identifies how much a transport centered importproduction-export chain is important for stable development of the RMG industry.
AUTOMATIC IRRIGATION AND MONITORING SYSTEM
(Daffodil International University, 2018-12-01) Ali, Md. Mohosin; Nahar, Lutfun
Watering the plant is that the most significant cultural follow and one among the labor intensive tasks in daily greenhouse operation. Watering systems ease the burden of obtaining water to plants once they want it. Knowing once and the way a lot of to water is 2 necessary aspects of watering method. to create the gardener works simply, the automated plant watering system is made. There have a varied kind victimization automatic watering system that are by victimization system, tube, nozzles and different. This technique uses watering system as a result of it will water the plants set within the pots. This project uses Arduino board that consists of ATmega328 Microcontroller. It’s programmed in such the way that it'll sense the wet level of the plants and provide the water once needed. This kind of system is usually used for general plant care, as a part of caring for tiny and huge gardens. Normally, the plants ought to be moiré double daily, morning and evening. So, the microcontroller needs to be coded to water the plants within the garden or farms regarding twice per day. Individuals get pleasure from plants, their edges and also the feeling associated with nurturing them. But for many individuals it becomes difficult to stay them healthy and alive. To accommodate this challenge we've developed a model that makes a plant a lot of selfsustaining, watering itself from an oversized tank and providing itself with artificial daylight. The pro-To kind reports standing of its current conditions and conjointly reminds the user to refill the tank. The system automation is meant to be helpful to the user. we have a tendency to hope that through this model individuals can get pleasure from having plants while not the challenges associated with absent or forgetfulness.

Effectiveness of Cognitive Behavior Therapy for Children with Anxiety Disorders
(University of Dhaka, 2021-04-04) Nahar, Lutfun
The objective of the study was to evaluate the effectiveness of cognitive behavior therapy (CBT) for the children suffering from anxiety disorders. For conducting the study 109 children and adolescents aging 717 with primary diagnosis of anxiety disorders from five government and nongovernment institutions were randomly allocated to CBT based treatment group (TG) or a waitlist group (WLG). CBT based Cool Kids Anxiety Program was used for intervention purpose. Assessment data during preintervention, postintervention (2 and ½ months from preintervention) and followup( 1 month from postintervention) were collected from both of the groups. It was found that the symptoms and comorbid other internalizing (depression, cognitive bias) and externalizing problems (negative behavior) decreased significantly in the CBT group or TG after the intervention according to both child and parent report when there was no significant change in symptoms in the waitlist group. The study contributes to the evidence base for using CBT as an effective intervention process in treating the anxiety disorders of the young population of our country.
Impact of Training Program on Awareness and Practice of Computer Ergonomics among Academic Staff
(East West University, 2020-07-06) Kabir, Rubayat; Sultana, Marzia Zaman; Nahar, Lutfun
In this advanced era, the education curriculum has a significant dependence on the use of modern technological devices such as computers. Improper use of such devices may, however, accompany a number of occupational health hazards like repetitive strain injuries. This in turn can affect the productivity of academic staff. The purpose of the study was to assess the knowledge and practice of computer ergonomics and its associated health-related disorders and also to evaluate the effectiveness of training in the given matter. Quasi-experimental research design; one group pretest-posttest of 103 academic staff of two private and two public universities in Dhaka was employed to observe the effectiveness of computer ergonomics training. The study participants were subjected to self-report inventory and observation of computer workstation. Moreover, in-depth interviews were conducted on six participants. After the baseline survey, participants were given training in computer ergonomics and a three month window period was allotted before post-training evaluation. Findings reveal that the major reported pain was in the back, shoulders and neck region. Multivariate analysis shows back pain (p=0.048) and overall MSE pain (p=0.043) to be significantly higher among public university academic staff. The reported complaints among males to some extent was more for shoulders as compared to females (p=0.005). Back pain was lower among those who knew proper distance, height and location of the monitor (p=0.026) and practiced appropriate position of the keyboard and mouse (p=0.026). Neck pain was more among participants below 40 years of age (p=0.048). Then again, it was less for those who knew height adjustments of the workstation chair (p=0.008) and practiced proper monitor angling (p=0.002). Overall MSE pain was lower among participants who knew proper seat tilt, depth and width pan of the chair (p=0.002) and practiced proper monitor angling (0.001). Furthermore, Mcnemar test results show that the awareness and practice related to computer ergonomics significantly increased after training (p=0.000). As analysis reflects, MSDs are less among academic staff who have better knowledge and practice computer ergonomics. Also, the given training is seen to be effective to enhance the knowledge and practice related aspects. Nonetheless, to reduce and prevent the overall risk of MSDs, a multi prolonged approach is required.

(East West University, 1/1/2014) Islam, Sufia; Rizwan, Farhana; Nasrin, Nishat; Nahar, Lutfun; Ahmed, Muniruddin
This study was carried out to find out the presence of common enteric bacteria, such as, Shigella, Salmonella, pathogenic E. coli and Vibrio spp. in the street vended foods around the student campus of East West University (EWU) in Dhaka, Bangladesh. The study focused on the socio-economic, behavioral characteristics and practices with street foods among the students of EWU and the street food vendors around the campus. A total of 50 street food samples were randomly collected from fixed and mobile vendors around the EWU area and tested for the presence of microorganisms following conventional microbiological processes. In order to describe the characteristics and practices of students of EWU, 225 students were randomly selected and interviewed by using a structured questionnaire. Based on the availability, 150 vendors were also interviewed by using a structured questionnaire. Among 50 food samples, 46 (92%) had bacterial contamination of which, 6 samples (12%) were confirmed to contain different species of E coli and Shigella. Four types of food samples, namely shingara, cake, butter bun were found to be contaminated with Enteroaggregative E coli (EAEC) and lemon juice was contaminated with Enterotoxigenic E coli (ETEC). Two samples- khichuri and water collected from fixed vendor were contaminated with Shigella flexneri X-variant and Shigella flexneri 2a respectively. Among 55% students who consumed street vended foods, it has been observed that more female students (68%) consumed street foods than the male students (45%). Sixty five percent students washed hands before eating food and 56% of the students (n=207) who consumed street foods washed hands after using toilet. Fifty nine percent (n=22) of the students suffered from stomach ache and vomiting after consumption of the street vended food. About 61% vendors kept food open and 12% of them sold stale food. Nineteen percent of the vendors did not remove flies while roaming and 53% stored water in open pot. Among 150 vendors 23% were illiterate, 32% had educational status below the primary level and 45% of them had education above the primary level (5th standard). Fifty-nine percent of the vendors washed their hands after coming from the toilet and 11% washed their hands with soap before preparing food. A significant relationship has been observed between the educational status of the vendors and their hand washing practice before preparing food (p= 0.0008). There was also a significant difference between the educational status and hand washing practice of the vendors after coming from toilet (p=0.029). The present study revealed that 92% of the street vended foods around an educational institution of Dhaka city had bacterial contamination. Six types of foods (12%) were found to be contaminated with Enteroaggregative E coli (EAEC) Enterotoxigenic E coli (ETEC), Shigella flexneri X-variant and Shigella flexneri 2a which could be a potential cause for food-borne diseases. Contaminated hands of food vendors can also be potential sources of pathogen transmission during the handling of the foods
