This study proposes a method for mining potential user requirements from users’ nonverbal behaviors by analyzing their operational problems, since human behaviors reflect emotions and operational bottlenecks in human-machine interactions. Taking a single daily operation task as an example, three key steps were included in the method: first, modeling users’ operation and constructing the operation chain; second, finding emotional or physical problems in the operation chain, where the problems were defined mathematically as an emotional or physical load at each suboperation; and third, defining and obtaining potential user requirements by improving the operational problems when performing a task. Furthermore, a daily operation task was introduced to demonstrate and validate the method of mining user potential requirements. The results indicate that it is effective to discover the potential needs for a specific product and provide satisfactory solutions by calculating and optimizing operational problems.

Design Steps

Conceptual design and requirement analysis are two of the key steps within the data warehouse design process. They are to a great extent responsible for the success of a data warehouse project since, during these two phases, the expressivity of the multidimensional schemata is completely defined. This chapter proposes a survey of the literature related to these design steps and points out pros and cons of the different techniques in order to help the reader to identify crucial choices and possible solutions more consciously. Particular attention will be devoted to emphasizing the relationships between the two steps describing how they can be jointly used fruitfully.

Objective. The objective of this study was to examine practices and policies in place for the provision of targeted prevention and treatment of cocaine and Amphetamine Type Stimulant (ATS) users in prison in nine European countries. Methodology. Across nine European member states (Belgium, the Netherlands, Czech Republic, Lithuania, Slovenia, Sweden, Malta, Ireland and Portugal), interviews were conducted with ministerial representatives and professionals (i.e. service providers and security officials) working in prisons and a total of 16 focus groups with a total of 125 prisoners. Results. The use of stimulants in prison is associated with aggression and violence, financial problems, and psychological and physical problems in prisoners (depression, anxiety and psychological craving). Both security and healthcare staff in prison often feel ill‐equipped to deal with stimulant‐related problems, leading to a lack of equivalence of care for stimulant users in prison, therefore the variety and quality of drug services outside is not reflected sufficiently inside prison. There is a need for more specific product information and harm reduction material on stimulants, for clear guidelines for the management of acute stimulant intoxication and stimulant withdrawal, for structural adjustments to improve potential diagnosis of personality and psychiatric disorders, for more non‐pharmacological treatment strategies and more opportunities for prisoners to engage in purposeful activities.

Based on the experiences of three research groups using and evaluating the Cognitive Interviewing Reporting Framework (CIRF), we draw conclusions about the utility of the CIRF as a guide to creating cognitive testing reports. Authors generally found the CIRF checklist to be usable, and that it led to a more complete description of key steps involved. However, despite the explicit direction by the CIRF to include a full explanation of major steps and features (e.g., research objectives and research design), the three cognitive testing reports tended to simply state what was done, without further justification. Authors varied in their judgments concerning whether the CIRF requires the appropriate level of detail. Overall, we believe that current cognitive interviewing practice will benefit from including, within cognitive testing reports, the 10 categories of information specified by the CIRF. Future use of the CIRF may serve to direct the overall research project from the start, and to further the goal of evaluation of specific cognitive interviewing procedures.

Objectives: The aim of this study was to investigate the actual condition of the students of University of Rajshahi (RU) regarding drug abuse and addiction. Using case study method the research was conducted with four objectives: (a) to find out how respondents began drug abuse; (b) to discover the causes of their drug addiction; (c) to understand the process of their drug abuse; and (d) to find out the economic, social and health effects of drug abuse. Methods: Case study method was used in this research. Through snowball sampling 18 drug- addicted students of RU were selected as respondents. In-depth interview with a schedule was used to collect data from the respondents in January 2019. Results: Findings of the study show that the causes of drug addiction included curiosity, frustration, friends’ request, neglect from family and friends etc. The drugs which they usually abused were Yaba, Phensydyle, Ganja (Weed), Chuani etc. Their average monthly expenditure for collecting drugs was in between Taka 8,000-10,000. They collected those drugs from rickshaw pullers at different points within the campus and from Mizaner Mor, Budhpara slum and other places outside the campus. The respondents opined that drugs were available if sufficient money could be spent. The respondents had senior and junior fellow students and local boys as companions while taking drugs. Most of them faced physical problems after taking drugs, and some of them tried to get rid of this curse of drug addiction. Conclusion: The findings of this research show that the rate of drug addiction among the students of RU was quite alarming. Therefore, all stakeholders including the students, guardians, teachers, university authority, the law makers and law enforcing agencies, researchers, civil society, NGO’s and the state must come forward together to combat this formidable foe.

Food sensory analysis is the terms from the field of Food Technology that has a meaning which means sensory evaluation of food that is conducted by the food sensory evaluators. Currently, food sensory analysis is conductedmanually. It can caus e human errors and consume much ti me. The objective of this research is to build a web based application that is specific for food sensory analysis using PHP programming language. This research followsfour first steps of waterfall software engineering mod el which are user requirements ana lysis (user software and requirements analysis), system design (activity, use cases, architecture, and entity relationship diagram),implementation (software development), and testing (software unit, functionality, validit y, and user acceptance testing). T he software result is well built. It is also acceptable for users and all functionality features can run well after going through those four software testing. The existence of the software brings easiness to deal with the manual food sensory analysis exper iment. It is considered also for the future it has business value by having open source and premium features.
