Agile and systematic development is important in Web application methodology because clients expect their frequent requirement changes to be implemented rapidly and regularly. However, previous studies may not be suitable for such development.In this paper we propose a methodology for agile and somewhat systematic development of Web application. The methodology includes models, tools, and an agile process. The models extended from UML focus on the behavior of Web application. The agile process aims to have quick-to-market property and adaptability to requirement changes. Tools including Process Manager and Web Modeler support process execution and modeling activity to guide developers in applying the process. An example of university assets management system and a comparison between our methodology and other processes are given to validate our methodology.

Test driven development uses unit tests for driving the design of the code. Mock object is an object that imitates the behavior of an object with which class under test has an association to assist the unit testing. Although many tools for mock object are used in practice, there has been few research on defining the mock object model. For the comparisons of the testing capability of the tools, it is important to define the models. In this paper we represent the models of the existing mock object tools and indicate the limitations of them. In addition we propose a new model to overcome the limitations of the existing tools. With this model, more general behavior of the class under test related to the mock object can be expressed and tested.

Background The global population is aging rapidly, and accordingly, the number of patients with dementia is increasing every year. Although the need for dental treatment increases for various reasons in patients with dementia, they cannot cooperate during dental treatment. Therefore, behavioral management, including sedation (SED) or general anesthesia (GA), is required for patients with dementia. Thus, this study aimed to investigate the trends and effects of SED or GA in patients with dementia undergoing dental treatment in South Korea based on the Korean National Health Insurance claims data. Methods This study utilized customized health information data provided by the Health Insurance Review and Assessment Service. Among patients with records of using sedative drugs during dental treatment from January 2007 to September 2019, patients with the International Classification of Diseases-10 code for dementia (F00, F01, F02, F03, and G30) were selected. We then analyzed the full insurance claims data for dental care. Age, sex, sedative use, and dental treatment of patients were analyzed yearly. In addition, the number of cases of GA or SED per year was analyzed, and changes in behavioral management methods with increasing age were investigated. Results Between January 2007 and September 2019, a total of 4,383 (male, 1,454; female, 2,929) patients with dementia received dental treatment under SED or GA. The total number of SED and GA cases were 1,515 (male, 528 ; female, 987 ) and 3,396 (male, 1,119 ; female, 2,277) cases, respectively. The total number of cases of dental treatment for 4,383 patients with dementia was 153,051 cases, of which 2.22% were under GA and 0.98% were under SED. Midazolam was the most commonly used drug for SED. Conclusion Although gingivitis and pulpitis were the most common reasons for patients with dementia to visit the dentist, GA or SED for patients with dementia was frequently used in oral and maxillofacial or periodontal surgery.

Abstract-As a program written in multi-staged language can generate and execute code fragments in excution time, it is hard to predict how many code fragments will be generated in execution time. Therefore, current test coverages are not likely to give right answers when they are apply to a program written in multi-staged language because the program size could not be estimated easily.In this paper, we present static analysis which detects code fragments generated in execution time using abstract interpretation and prove the correctness of analyzer. Moreover we propose new test coverage for multi-staged language using the result of analysis.
