Form Design in Web Application Using the Three-Layer Model (TLM) : A Checklist Development

The objectives of end users visiting web site are generally for information retrieval whereas for web application, users have specific goals, which are to complete tasks successfully. Nevertheless, some online job applications do not meet task-based orientation design and this resulted in users’ frustration. Therefore, for the purpose of reducing the frustration and providing guidelines, a form design checklist was developed. In addition, an investigation of the current state of web form design among Malaysian developers was also conducted. A four-step methodology was followed; understand Three-Layer Model (TLM) concept, develop checklist based on guidelines, collect and identify existing Malaysian web forms, and finally, validate checklist and compare the collected web forms with the Three-Layer Model. In validating the checklist, 15 respondents performed three sets of tasks: pre-test, post-test and comparing three pre-selected online forms. Findings indicated that students designed better web forms after learning about the TLM and this suggests that the checklist provided guidance in designing better web form. Results also pointed out that the current state of web forms designed by Malaysian does not meet task-based orientation design

Towards interface design for virtual database / Zanariah Idrus...[et al.]

Today, big data has become as one of the important contribution in database management. It led to innovative ways of storing and organizing data which include structured and unstructured data. The unstructured data such as in news, reports, chats and surveys are basically loaded with heavy text data and numerous format. Thus, these data become challenging to be used for diverse purpose and are not appropriate to be stored in database. However, virtual database method has the capability to organize the unstructured data, and reconstruct into firm and concrete data. This approach carry out two major processes in databases which are mining and managing the data. However, the main problem is the insufficient support between people using databases and the heap of data collection. This is due to unawareness of clustered data organization as information is stored implicitly. Thus, this paper presents the conception of clustered data using the interface design model. Alignment of features and connections between the interface and knowledge composition allow users to access knowledge proficiently

A novel approach of hybrid guideline based on senior citizen online form design / Zanariah Idrus...[et al.]

The research focuses on the problems faced by the senior citizens during form filling process on web application services . By year 2020, The World Health Organization predicts the senior citizens population is more than 1 billion . They are progressively exposed to technology and to understand their requirements is significant in human interface design. Unfortunately , the online form interface design tends to ignore the issue of ease of use especially for senior citizens aged 55 and above. A well known Delivering Inclusive Access to Disabled and Elderly Members (DIADEM) guideline outlines the recommended online form design for the senior citizens. Recently, DIADEM guidelines were implemented in Europe and the results suggest that it is important as a reference for senior citizens ' online form design . But it is specifically tailored for senior citizens with age 65 and above only . WeFDeC guideline aligns the online form design based on the Three Layer Model (Perceptual , Conversational and Relationship layers). Though it is an acceptable guideline for online form but it does not take sen ior citizens into consideration . Therefore , this study will compare , identify the weakness and create a new hybrid model of DIADEM and WeFDeC guidelines. A new model (Elder-WeFDe) which should fit with senior citizens online forms applications and the Malaysian e-government online forms will be introduced . The methodology follows five phases ; identify the research problems, identify and compare the two guidelines, produce a new permutation model and test the model to the Malaysian e-government forms. A form from the current 1169 online forms in Malaysia e-government portal will be selected and tested to a randomly selected group of senior citizens aged 55 and above from Malaysia northern region .The expected outcome is a new hybrid model (Elder-WeFDe) to guide web or online form designers to design a better and ease of use on line forms applications for the senior citizens and all age of group

Dynamic user management model in interactive networked collaborative environment / Siti Zaleha Zainal Abidin … [et al.]

Interactive networked collaborative virtual environment (NCVE) provides ways for people to work together, faster and cheaper despite of locations. Results can be achieved without travelling time and spending more money. Unfortunately, users' existence is not visibly presence which results in lacking of user participation that seriously degrades communication quality. This leads to misinterpretation of vital information and jeopardize the group work. Therefore, it is crucial to present users so that others know with whom they are interacting with (presence), when to communicate (state) and what to do (role) during the collaboration. This research investigates the activities of users in order to identify all the possible job functions exist during collaboration. Then, their job functions are classified in relation to the management of dynamic invisible users (their presence, states and roles). The users' role, presence and state will be generalized to form a generic management model of dynamic users based on logical notation. This work employs data collection through literature review and a case study. For a case study, a monopoly game will be implemented by changing some of its rules to gather all the possible roles exist throughout the game. The game is also used as a platform to do an abstraction of real life phenomena. A mapping of users' job functions found in both literature review and the case study will be conducted to produce comprehensive elements for managing users in collaborative systems. All the elements and their relations are classified and represented as a set of mathematical equations. The model helps to manage users dynamically throughout the collaborative session. This session-based dynamic role feature is rarely found in any collaborative work as compared to application-based role. Furthermore, managing users in virtual space is challenging because it involves security, privacy and permission to information resources

Truck queuing analysis at landfill sites in a waste collection vehicle routing problem

This paper presents an analysis of a truck queuing problem at landfill sites due to a static rest time of truck drivers in a waste collection vehicle routing problem. The analysis is based on a solution of two datasets from a benchmark waste collection problem using the nearest greedy heuristic algorithm.In this problem, all drivers need to have a one-hour rest break during their collection.The rest break can start from 11.00 a.m. to 12.00 p.m. However, based on the solution from a previous study, all drivers have their rest break almost at the same time. Consequently, all drivers travelled to landfill sites to unload waste approximately at the same time.Based on the truck queuing analysis presented in this paper, there is a long queue at landfill site 3 (ten trucks arrived between 2.52 p.m. to 2.53 p.m.) for dataset 1; whereas for dataset 2, 13 trucks arrived at landfill site 1 between 4.10 p.m. to 4.55 p.m. Thus, it may be concluded that the static rest time period of truck drivers can cause truck queuing at landfill sites. Long queues at landfill sites will increase the service time at landfill sites as well as affect the drivers’ arrival time at customers. This paper suggests that future works need to consider a dynamic rest time period in solution techniques to overcome the truck queuing problem at landfill sites for solving the waste collection vehicle routing problem

Development of a computer simulation on road pricing strategy to reduce congestion and carbon dioxide emission: A system dynamics approach

Road congestion influences the quality of lifestyle for urban areas including Kuala Lumpur, the capital city of Malaysia. It is predicted that the demand for mobility in the city will be increased tremendously in the next ten years. Consequently, this problem has contributed to air pollution caused by carbon dioxide emissions. One of the solutions suggested by the expertise is road pricing via a direct charge to drivers who use the road during peak hours. In this regard, this research aims to develop a computer simulation based on a system dynamic approach for mitigating congestion and carbon dioxide emission via a road pricing strategy. Firstly, the identified variables were correlated to understand the behavior of the system. Subsequently, the correlated variables were embedded in the stock-flow diagram based on the system dynamics approach to investigate how a variable affects another variable. Then, the developed model was simulated for evaluating the impact of road pricing strategy in reducing congestion and carbon dioxide emission. As a result, the emission of carbon dioxide can be reduced to 6 percent in six days if road pricing is implemented. From the managerial perspective, this research helps highway stakeholders in Malaysia towards making a better decision in enforcing road pricing strategy in the fast-moving city for a better lifestyle and environment

In validating the checklist, 15 respondents performed three sets of tasks: pre-TLM, post-TLM and comparing of three pre-selected online forms. Findings indicated that participants designed better web forms after learning about the TLM and this suggests that the checklist provided guidance in designing better web form. Results also pointed out that the current state of web form designed by Malaysian seems to suggest that it does not meet task-based orientation design

Integrated the different data from the variety database for querying motif sequence / Mohd Taufik Mishan, Zanariah Idrus and Jasmin Ilyani Ahmad

In performing protein secondary structure prediction procedures, biologists need to use variety types of sequence data from multiple biological repositories which are available publicly in the Internet. A lot of researches have been done in minimizing the numbers of repositories needed for the prediction procedures. However, due to the size complexity and numbers of repositories used has created a major challenge in integrating all different data into one repository or database. This challenge is known as syntactic heterogeneity problem. The aim of this research is to overcome the problem by transforming all the different data form variety of databases such as Prosite, Blast, Print and PDB into flat file format and other format into relational form using XML and asp dot net. From studies that have been conducted, XML approach is considered as a better choice for biological data integration. And this research has reveals that query made from relational database incorporating XML schema gives better query performance after integrating the variety data into one repository or relational database using metadata framework. As a result, this research showed some tool can search different data and different sizes of protein secondary structure data stored in the relational database and the result can be retrieved faster and reliable

Self-esteem among high achievers of Islamic Revealed Knowledge and Human Sciences students

A survey was conducted to investigate the relationship between self-esteem and high academic achievement. It is hypothesized that high academic achievers are more likely to possess high self-esteem. Fifty undergraduate students (41 females and 9 males) who received Dean’s List and obtained a GPA of 3.50 and above were contacted and selected as respondents. The questionnaire used to evaluate self-esteem was a modified version combining Rosenberg’s Self Esteem Scale and Coopersmith’s Self Esteem Inventory with some additional items developed by the present researchers. The correlational analysis showed a significant, positive correlation between self-esteem and high academic achievement with r = .626, p < .001. The implications, limitations, and suggestions of the study are discussed
