  • Crowdsourcing is growing its interests in designing where various designers work independently to a given design task. Recent researchers discovered that collaboration by sharing designs among designers helps to produce high-quality designs. However, design task may still be hard even with that collaboration in case the requirements are not well-defined. Most customers sometimes do not know what they really want and do not know how to clearly define the requirements. Consequently, the lack of requirements creates issues on designers, such as spending much time and effort on collecting requirements alone or from the customers. The designers even end up missing important necessities to complete their tasks. To address this issue, we proposed a collaborative requirements elicitation method that supports designers who are working on the same task. We developed CREFD (Collaborative Requirements Elicitation For Designers and Developers) tool to enable designers collaboratively provide requirements, identify dependencies, add annotations and votes to the provided requirements. We performed the hypothetical and empirical evaluations to test and compare the proposed method with one of the existing elicitation methods, the results show that the proposed method helps in collecting accepted and well-organized requirements better than individual requirements elicitation.

  • This paper proposes a method for counting function point using goal and scenario based requirements. Function Point is a software sizing method and widely used as a basis to estimate software development cost. Requirements elicitation and analysis should be performed before function point analysis but function point analysis method doesn't deal with requirements elicitation and analysis. For that reason, Function point extraction method from existing requirements method is needed and if the requirements method has advantage for traceability and elicitation, it is suitable for managing cost. Goal and scenario method is widely used as requirements elicitation and analysis. It has also good traceability. Therefore, this paper discusses a method for extracting function point from requirements text gathered using the goal and scenario based requirements elicitation technique. The proposed method aims to establish and maintain traceability between function point and requirements text. Text based function point extraction guidance rules have been developed. The proposed methodology has been applied to Order Processing System development.

  • Even though context is the most important feature in context-aware systems, the existing requirements engineering cannot support methodology for elicitation and specification of contexts. In this paper, we propose a requirements elicitation method and a requirements specification method for context-aware systems. Our requirements elicitation method is a 6-stepped, incremental, and iterative process. At the beginning steps in the process, we identify the requirements for business logic. Afterwards, we gather the requirements for context logic, model contexts, and identify subsystems. For requirements specification, we suggest a context-aware use case diagram, a context diagram for context modeling, and a context-type-use-case-dependency diagram for the traceability of use cases on the change of context types. We also introduce a case study that we apply our approaches to a real system, and a qualitative evaluation of our approaches. Our study will help stakeholders to efficiently elicit requirements for context-aware systems and to specify them clearly.

  • Objective : The purpose of this study is to examine the effects of Gamisipjeontang-gamibang(GT) on an experimental bum elicitation. Method : The absorbance of the photo cell mixed with GT at the Abs 560 nm was measured after irradiation for 1 min. In order to know the antioxidant effect on skin cell of mice after burn elicitation, superoxide dismutase(SOD) activity was measured. Also, in order to know effects on the skin regeneration in the burned mice, we counted the eosinophil in blood from animals via cardiac puncture and observed the histological structure in the epidermal basal layer and the dermal section on the 3rd, 7th and 14th day after burn elicitation. We also studied changes in angiogenesis in the capillary surrounding the basal layer and dermal papilla. The changes of HSP70 distribution and changes of p53 positive reaction were observed to investigate the changes of the stress in the skin as well. Result : The results indicated that GT has a significant impact on the antioxidant effect on skin cells of mice after bum elicitation by increasing SOD activity in vitro test. GT seems to decrease MIP-2 which induces neutrophil infiltration and promotes the angiogenesis dose-dependently. Furthermore, GT decreased HSP70, the expression of which was induced by elevated temperatures, and p53 which induce a apoptosis after stress. Conclusion : GT can be applied to burned skin through its antioxidant effect and skin regeneration property.

  • Target businesses mean a business of specific and detailed management targets being used for realization of applications for business. Though elicitation methods of target businesses exist variously, it mostly requires much experience and consumes much time. So because its procedure is not suggested clearly, there is much difficulty when a beginner elicits target businesses. Accordingly, this study proposes a method capable of eliciting target businesses procedurally from given business statements. And hypothetical business statements were used as a case, and a method proposed from this study was applied to given business statements with the target of undergraduates, graduate students and company employees. And as a result of questioning an individual performance method and analyzing its reliability, a reliable result was obtained generally. Due to this, it could be confirmed that the method suggested in this study is not only used in the field, but also can be used easily even for a beginner.

  • In Requirements engineering, requirements elicitation and analysis are very important tasks to develop software systems successfully. Even though various methods have been proposed including scenario-based analysis, goal based analysis, and coupling goal with scenario, each method has its own strengths and weaknesses. If you use only one method, it is very difficult to elicit and to analyze system requirements completely. Since these methods don't support a comprehensive elicitation process, this paper proposes an integrated approach. This integrated approach is focused on two viewpoints. One is what factors are comprised and the other is how they are integrated. This paper also shows how the proposed approach can be applied to Meeting Reservation System (MRS) development. An experiment has been conducted using this approach to demonstrate how complete requirements are elicited and analyzed and to show relative time savings during elicitation in comparison to each method.

  • In the early stages of a software project, it is critical to understand the needs of the customers and elicit their customer requirements. Various requirements elicitation methods have been proposed. However, existing methods still have the limitations such as a limited number of target customers, limited expression of customers' opinions, and difficulty in collecting the customers' opinions continuously. A novel method for eliciting customer requirements is proposed by utilizing a social network service (SNS), which is a shared source of raw information of the customers' needs and opinions. The proposed method is validated to show its effectiveness in overcoming the limitations of existing methods.

  • Shopping malls in Korea have grown in size and number, and their one-stop convenience has expanded to include various retail stores, service outlets, and entertainment providers. This study closely examines the shoppers' experience in a shopping mall. Using the photo elicitation interview (PEI) method, this study aims to provide deeper understanding of the subjective perceptions and context of shopping mall users. Ten shopping mall users participated in this study. They visited a shopping mall and took photos from their points of view about the shopping experience, and later participated in a personal interview. Convenience, excitement, relaxation, and socialization are the major themes of a pleasant shopping mall experience. Crowdedness and ineffective store design are the major themes of an unpleasant shopping mall experience. Core contents of each pleasant and unpleasant theme are presented. Given the current retail environment where shopping malls are continuously expanding, understanding the behavior and perception of consumers related to shopping malls is important in designing and providing a compelling experience in shopping malls.
