A Survey of Attention Deficit Hyperactivity Disorder Identification Using Psychophysiological Data

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common neurological disorders among children, that affects different areas in the brain that allows executing certain functionalities. This may lead to a variety of impairments such as difficulties in paying attention or focusing, controlling impulsive behaviours and overreacting. The continuous symptoms may have a severe impact in the long-term. This paper explores the ADHD identification studies using eye movement data and functional Magnetic Resonance Imaging (fMRI). This study discusses different machine learning techniques, existing models and analyses the existing literature. We have identified the current challenges and possible future directions to provide computational support for early identification of ADHD patients that enable early treatments

Sustainable development through proper land utilization Case study Ratnapura, Sri Lanka

Since the land is a scarce resource, the utilization of land effectively would be directly affected to thesustainable development of any country. A proper system ofland uti Iization is very essential especiallyfor a country like Sri Lanka which is very small in size and the majority of the people are dependingon the land related activities such as farming, grazing etc. as their major source of income. Unfortunately,land is in the state of under utilization in Sri Lanka. This paper attempts to study the importance of theeffective land utilization using Geographical Information Systems (GIS) for the sustainable development.The study was mainly based on the data gathered from Ratnapura Divisional Secretary area, Thearea is consisting with natural vegetations such as forests, shrubs. and man -rnade cultivation such astea, rubber, paddy. Also the area has a high economic value and it is well known for natural disasterssuch as floods and earth slips. Primary data was collected using semi-structured questionnaires,interviewing people and relevant officers and field surveying using hand held Global Positioning System(GPS). The study supplemented with secondary data such as remote sensing satellite images, existingmaps. GIS technique was used for the data analyses.The study identified 4 major issues in the specified areaI. 20 % of the total area is under utilization2. 25 % of the total area is misused3. 05 % of the total area is over utilized4. Continuous loss of land due to the natural disastersAccording to the results, the land has not used effectively in the area. 45% of the area is not usedeffectively. Since the country is very small, proper land utilization is very important. The study suggestthat an immediate action should be taken to overcome the matter. And also it is very important to getthe active participation of the general public to stop the loss ofland due to natural disasters and forfuture decision making. 

Reasons for the deviation in the Final Pre-Production Completion in Apparel Industry: Case Study

Sri Lanka’s apparel and textile manufacturing industry is the most significant and dynamic contributor to the economy. A key success factor of the industry is the high level of quality in the final production which delivers to the customer. This depends on many internal procedures within the organization. The final pre-production (PP) is one of those significant stages in the internal manufacturing process, which impacts the quality and completion time of the bulk production. Repetitive delays in the final pre-production (PP) completions which holds the entire bulk production was observed as an empirical problem in one of a leading apparel manufacturing company in Sri Lanka. Hence the primary objective of the study is to investigate reasons for the delays in final PP completion. Research methodology follows an interpretivism philosophy with an inductive approach. The strategies of data collection were based on a case study method which includes deep observations of 240 hours on the production floor and interviews as primary data collection sources and historical data of the organization as the secondary data. Study used Plan-Do- Check-Act (PDCA) cycle with an eight-step problem solving method to analyze the data. Findings of the study are; delays in pre-production sample approval, issues with material quality assurance, materials and trimming sources, development center, factory authorized auditor, machines unavailability. This study contributes to the existing literature and apparel sector by providing fine-grained recommendations to the field such as enhancing the collaborations on cross functional team tasks, sharing responsibilities of the feedback mechanisms in the production process and to increase the plant technical team involvement on each stage of the process.

The Impact of Covid-19 on Small-Scale Women Entrepreneurs In Sri K. Lanka: A Qualitative Study of the Matara Area (SK Town and Meddawatta)

COVID-19 has impacted people across the world regardless of geographical boundaries, gender, age, and economic status. However, women have become disproportionately more vulnerable. To explore women entrepreneurs’ experiences, the difficulties they face, and the strategies they employ for the survival of their businesses, this study selected Matara district as one of the most famous coastal areas of the southern province, and Sk Town and Meddawatta as the most popular tourist destinations of this district. This qualitative research employed a purposive sample of 15 females. Data collection for this research was mainly done through interviews (face-to-face, telephone, and WhatsApp calls), participants’ observations, and cyber ethnography. All of the participants, though not hit by the virus, have been impacted by COVID-19 related social and economic problems. Although all the participants suffered loss of income, surprisingly, the pandemic led some women to focus on exploring new income-generating activities. The research shows, as narrated by the respondents, that small- and medium-scale female entrepreneurs have not received adequate attention or help for the amelioration of their plight from government-led welfare activities, including bank loan payment extensions.</jats:p

Atypical Presentation of Myocardial Ischaemia as Referred Pain to Jaw in a Young Adult-A Case Report

Ischaemic Heart Disease (IHD) accounts for the highest mortality rate among the non-communicable diseases across the globe. In the developed countries the incidence of IHD has shown a slow decline over the past two decades. It is traditionally considered as a disease of the elderly though clinicians and pathologists experience more and more younger individuals getting affected by the condition since last few decades due to a variety of reasons. IHD has a variety of presentations some of which could lead to diagnostic difficulties unless due caution is exercised. Isolated referred pain to teeth, jaw or craniofacial region is one such rare presentation for which many theories have been put forward to explain the mechanism though none is conclusive. When a patient complains of an unusual pain in the craniofacial region or the jaw, the remote possibility of its cardiac origin should always be born in mind. Otherwise it could not only lead to unnecessary dental interventions but also it could unduly delay the diagnosis and treatment of a more serious health condition sometimes leading to severe morbidity or even death. This case illustrates a situation where a young male suffering from intermittent tooth pain/jaw pain for over a period of three months, seeking dental treatment including extractions and restorations from a qualified dental surgeon, suddenly collapsed and died at workplace after complaining of excruciating tooth-pain. The cause of death was established after meticulous post mortem examination as IHD due to coronary thrombosis
