The purpose of this study is to suggest consideration and direction of collaboration among different industrial field in Korea which has recently increased through the analysis of design collaboration case of cross-business in domestic. To do this, I did literature research followed with theoretical background of collaboration, and I analyzed case study of collaboration between different industries in domestic. In addition, I categorized as millennial targeting and brand premium positioning shifts. As a result, brand have to select a partner that is appropriate and would be an issue for purpose of collaboration and that the result should have a clear difference from existing product, including the design elements of the brand that they want to highlight. I expect this research will become a reference for collaboration between different industries.

The purpose of this study is to study the elements that make up the interface design of the applicatio, focusing on Android's Google Material Design Guidelines. and propose a way to produce the UI design guide by categorizing it according to form and combination methods. The components provided by the Materials Design Guidelines were disassembled form and attributes, types, and the characteristics. The components of UI design include surfaces, letters, icons, and media, which enable the creation of UI style guides, and the components for the purpose of exploring and communicating information, with different components and rules of use used for the purpose. Based on these results, I would like to propose design criteria for the interface of mobile applications and how to utilize it effectively.

Nowadays u-healthcare which is very sensitive to the character of user's information among other ubiquitous computing field is popular in medical field. u-healthcare deals extremely personal information including personal health/medical information so it is exposed to various weaknees and threats in the part of security and privacy. In this paper, RFID based patient's information protecting protocol that prevents to damage the information using his or her mobile unit illegally by others is proposed. The protocol separates the authority of hospital(doctor, nurse, pharmacy) to access to patient's information by level of access authority of hospital which is registered to management server and makes the hospital do the minimum task. Specially, the management server which plays the role of gateway makes access permission key periodically not to be accessed by others about unauthorized information except authorized information and improves patient's certification and management.

This study provides two channel structure and two factor authentication. First, a purchasing request by Internet and then user certification and a settlement approval process by mobile communication. Second, it support that proposal protocol utilize a partial factor value of stored in users smartcard, smart phone and password of certificate. Third, storage stability is improved because certificate store in smartcard. Finally, proposal protocol satisfy confidentiality, integrity, authentication, and non- repudiation on required E-commerce guideline. In comparative analysis, Efficiency of the proposal protocol with the existing system was not significantly different. But, In terms of safety for a variety of threats to prove more secure than the existing system was confirmed.

This is a user experience study of factors that should be considered in designing home appliances experience service. Untact services are emerging, but the development of home appliances sector is in early stage. Based on the six factors of Stephen P. Anderson's Creating Pleasurable Interface Model, this study conducted surveys, 1:1 in-depth interviews, and participation observations to measure and analyze user experience. In this study, I compared 4060s and 2030s's user experience in that the untact services raise the digital alienation among middle-senior-aged. As a result, there were significant differences between the two, including the opposite satisfaction in terms of reliable, usable and pleasurable factors. I hope that this study will be of strategic help in designing future home appliance experience services.

Machine learning as a service, the so-called MLaaS, has recently attracted much attention in almost all industries and research groups. The main reason for this is that you do not need network servers, storage, or even data scientists, except for the data itself, to build a productive service model. However, machine learning is often very difficult for most developers, especially in traditional science due to the lack of well-structured big data for scientific data. For experiment or application researchers, the results of an experiment are rarely shared with other researchers, so creating big data in specific research areas is also a big challenge. In this paper, we introduce the KISTI-ML platform, a community-based rapid AI model development for scientific data. It is a place where machine learning beginners use their own data to automatically generate code by providing a user-friendly online development environment. Users can share datasets and their Jupyter interactive notebooks among authorized community members, including know-how such as data preprocessing to extract features, hidden network design, and other engineering techniques.

The purpose of this study is to conduct research from qualitative aspects regarding the development of substantive design research for furniture brand and detailed development direction as single household has increased rapidly. In case of research method, the usability evaluation questionnaire was produced based on Honey Comb Model of Peter Morville. As a result, the single-person household including other household show preference for furniture for the one-man households and tend to purchase and use them. Nonetheless, it was found that places for sharing opinion and reselling the furniture are greatly lacking. Therefore, it is required to vitalize community market for the one-man household. And it is expected that this result of research provides useful implication concerning the single household as well as academic significance to offer primary information of furniture brand development-related research.

The purpose of this study is to suggest a leisure activity for improvement of personal life and career of Korean workers. To do this, DIY was selected as a method of leisure activity that minimizes cost, time and space contraints. As a method of research, I did case study for investigating the characteristics of existing leisure activities. In addition, I examined the needs about cooking activity through an in-depth interview with 8 workers whose hobby is cooking. As a result, two essential elements were derived. First, it is necessary to establish a clear scope and content of the brand. Secondly, a platform for sharing activity is needed. This study is significant in that it suggests the way to improve leisure activity of workers. After this study, it is expected that it will help to spread leisure activities of workers through the design of leisure activities plan.

The lifestyle of the new consumer class of people with diversified social structures and tastes is affecting society as a whole. As of now, emerging lots of complex cultural space with unique sensibility and individuality, this paper is about proposing the branding of a complex cultural space. I selected Sounds Hannam as a cultural complex and conducted in-depth interviews about brand experience and Ethnography. The study found that Sounds Hannam needs sense of hearing and smell because the sensory factors of the Sounds Hannam are concentrated in the visual field, and also, there is a need to create an appropriate communication channel through SNS. The Sounds Hannam had the characteristic factors of sensibility, relaxation and content based on a diversity different from the existing one. Throughout research, it was derived that planning space as a place to inspire people through spatial composition that triggers behavior and creative thinking is the goal of a complex cultural space and at the same time, an effective way to reflect the lifestyle of those in 20s.
