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.

3GPP (Third Generation Partnership Project) is defining UMTS (Universal Mobile Telecommunication System) releases which span the transition from GSM/UMTS coexistence to All-IP UMTS networks. The deployment of an UMTS network depends, in the first place, on the intended service offerings and the release an operator chooses to start service with. Other key decisions in-fluencing UMTS deployment relate to the timing of the functional enhancements and capacity increases along the economic life of the network. This paper gives an overview on the architectural and technical options for UMTS deployment. It also outlines the methodology underlying the business plan aimed at estimating the returns from investments in the UMTS infrastructure, thus helping to tune operators’ strategies for UMTS deployment.

As corona began to spread around the world, it had such a big impact on many people's lives that the word "Untact Culture" was born. Among them, non-face-to-face meetings naturally became a daily routine as educational institutions and many domestic and foreign companies used video conferencing service platforms. Among many video conferencing service platforms, Zoom, the company with the largest number of downloads, caused many security issues and caused many concerns about Zoom's security. In this paper, Zoom's security problems and vulnerabilities were classified into five categories, and Zoom's latest update to solve those problems and the 90-day security planning project were compared and analyzed. And the problem was solved and classified as unresolved. Three of the five parts have been resolved but are still described as how they should be resolved and improved in the future for the two remaining parts.

Building Information Modeling (BIM) is a nascent technology in Korea, and currently lacks formal guidelines to assist Architectural and Engineering (AE) firms in estimating BIM service fees, while also allowing government agencies to allocate budgets for the rendered BIM services. This research provides a method to estimate costs for BIM services based on the cost-plus pricing framework. The approach requires a generalized estimate of the man hour per floor area data to calculate the direct labor costs. Man-hour data were collected from forty five projects that have implemented BIM. Interpolation of the man-hours was performed to develop a general reference table for 'Type 2' (i.e., public schools and office buildings, etc.) projects. By providing an objective approach for estimating the costs of BIM services, it allows clients and AE firms to agree upon a fair cost for BIM related services, and thus expedite its adoption in Korea.

In this study, it was intended to explore a way to build a DB which links the resources and areas and regions already registered as cultural assets in connection with a project which is newly building local culture and arts resources. Towards this end, this study first identified the type and scale of existing local culture and arts resources that could be linked. Following which, to link the local cultural resources and collected cultural assets, this study investigated the websites such as the Cultural Heritage Administration's National Cultural Heritage Portal, municipal and provincial tangible cultural festivals, municipal and provincial intangible cultural assets, and Gyeonggi Memory. Furthermore, this study identified the amount of information sources to be built and the current status of each information source to identify detailed information sources. Finally, the metadata of local culture and arts resources were presented by classifying them into material and publication data metadata, document metadata, audiovisual metadata, oral recording metadata, village information metadata, and personal information village information metadata.

This study proposes an entrepreneurship education process for fashion product start-ups through rewards-based crowdfunding. It examines issues such as: the general concept of crowdfunding and the pros and cons of rewards-based crowdfunding, the detailed curriculum plans in a chronological order for the regular class development, and the presentation of a visual plan to show the whole process. An entrepreneurship education process is developed in 13 steps: research on crowdfunding market, prototype plan, prototype production, story development, visual contents development, rewards development, project evaluation, public schedule & service setting, period setting & start funding, community management (Q&A), funding ends & deposit, complete manufacturing & start delivering, and the final information disclosure & open the next project plan. This research is intended to investigate rewards-based crowdfunding as a new paradigm of entrepreneurship and apply entrepreneurship education in fashion product development. However, it is limited to studying the Wadiz crowdfunding platform in Korea. Therefore, we propose a case study on various crowdfunding platforms in Korea, a case study on entrepreneurial curriculum application, and a follow-up study on the possibility of entry into an overseas crowdfunding platform.

Oral history has value that steps over the class consciousness and party feeling that records have, and enables a general representation of a human experience. Beside, It must be managed urgently because a collection of oral history has unique and limited. However, domestic related institution do not keep management for release and use of oral history in their mind are only concentrating on accession. Lately, National History Compilation Committee passes through faithful planning procedures and is collecting an oral history collection project. A merit of this project is to have attempted an image photographing. This study is propose that to examines over the all steps to say oral history collection activity to information service and a preservation from collection planning of organization. However, this study is insufficient in the management method how it is connected if does in order to manage the oral history which is collected with a part of a record in a archival institution because this study was only for the purpose of management of oral history. This problem will be studied through a process of checking the real thing of oral history. This study proposed general methodology for oral history management, if institution had a plan of collection and management or had some collection result.

Expectation for improvement of creativity and problem-solving capability has increased the creative robotics classes in the form of after-school activity in more than half of total elementary schools. While Ministry of Education, Science and Technology has promoted 'Green IT Guidelines' as a part of 'Eco-friendly Green School Development Project', the Green issues have not been considered enough in those creative robotics classes. In this paper, we would like to address the Green issues, especially in the r-Learning services based on UCR (User Created Robots). First, trend of green IT education, r-Learning services and UCR are reviewed. And the current status of eco-related operations and teachers' perception in the robotics classes of elementary schools is investigated. Examples of Green UCR are also searched and green programs based on the three kinds of UCR, UC-TR, UC-AR, UC-CR, are explored. Finally, we propose action plans to promote the UCR-based r-Learning service reflecting green issues.
