This paper discusses the significance of nonmonotonic reasoning, a method from the knowledge representation area, to mainstream software engineering. In particular, we discuss why the use of defaults in specifications is an adequate way of addressing some of the most important problems in requirements engineering, such as: The problem of identifying and dealing with inconsistencies; evolving system requirements; requirements prioritization; and the quality of specifications with respect to naturalness and compactness. We argue that these problems need to be addressed in a principled, formal way, and that default reasoning provides adequate mechanisms to deal with them.

Modelling Methods

The dengue disease is caused by dengue virus, and there is no specific treatment. The medical care by experienced physicians and nurses will save life and will lower the mortality rate. A dengue vaccine to control the disease is available in Thailand since late 2016. A mathematical model would be an important way to analyze the effects of the vaccination on the transmission of the disease. We have formulated an SIR (susceptible-infected-recovered) model of the transmission of the disease which includes the effect of vaccination and used standard dynamical modelling methods to analyze the effects. The equilibrium states and their stabilities are investigated. The trajectories of the numerical solutions plotted into the 2D planes and 3D spaces are presented. The main contribution is determining the role of dengue vaccination in the model. From the analysis, we find that there is a significant reduction in the total hospitalization time needed to treat the illness.

Descriptive Method

The Directorate General of Agro-Industry is one of the implementing elements of the duties of the Minister of Industry, which has the task of organizing the formulation and implementation of policies. In order to encourage the growth and development of the role of the agro-industry, especially in providing informative information, which is very important in the current era of technology 4.0, publications and information facilities are needed regarding the development of the agro-industry. The design of this study used a descriptive method, using an object-oriented approach, while its development used a prototype model. This study aims to develop a website that is in accordance with several important factors that need to be considered so that website development can touch the quality side of the Ministry of Industry, Directorate General of Agro-industry which is in line with Law Number 14 of 2008 concerning Information Disclosure. This research produces a quality website at the Ministry of Industry, Directorate General of Agro-Industry, and meets the principles of good governance in accordance with Presidential Instruction No. 3 of 2003. So that the transparency and accountability of the information on this website are expected to have an impact on increasing the confidence of both local and foreign investors.
