The purpose of this study was to designed the structure and elements of metadata that can manage and share research data produced in the food composition database. In order to derive metadata elements, mapping crosswalk was performed on 5 metadata such as DCAT, DataCite metadata schema 4.4, TTAK.KO-10.0976, AgMES, and FoodData Central. As a result of the study, the top 15 elements of the 'Resource information' metadata were derived, and 7 mendatory, 3 recommended and 5 optional elements, and the 'Composition analysis' metadata included 8 mendatory, 3 recommended and 1 optional element were derived to describe food composition research data, respectively. The derived metadata elements will be used as an item for systematic management of food composition data and can be used as basic data for sharing with domestic and international food composition databases.

Hand rehabilitation training tools are used in hospitals and at home for patients and users who require recovery of disabled hands and improvement in overall hand function. However, existing training tools are not organized into a progressive system, and they lead to repeatability operations over a period of time. As a result, patients feel free and cannot be motivated by rehabilitation, and continuous rehabilitation training is difficult. Based on this argument, the study combines one of the elements of the game called the "Cat's cradle" to enable the user to feel achievement through play and to achieve natural rehabilitation through unconsciousness. After examining the characteristics of the tool, the user's environment, the relevance of the Cat's cradle game to the training tool and to the patient's continued rehabilitation was established. And design elements were derived through professional interviews. Later, design guidelines and prototypes have been created to complement the problems associated with guidelines and prototypes by conducting usability testing and design element assessment.

Nowadays, smart phone became an important part of communication media and integrated into people's life. If callers rely on helmet-mounted display(HMD) augmented reality technique to add two-way user's facial expression, appearance, actions during the calling process, it will let callers have a visualized fantastic sensual experience. And through that method can break the limitations of vision, so research that technical problem can promote the development of visual arts, that is meaningful. This paper will choose and composite several existed technologies to set up two hypothesis, try to realize AR video calling. Through comparison and analysis to find those two hypothesis' problem, and create design solutions to solve problems. And use case study method to present two cases for prove my paper's result that is those two hypothesis can be realize in future. Use those technologies can bring more convenience and enjoyment to people's life. It can be predicted that AR video calling process can be successfully realized and will have unlimited development in future.

Education using smart mobile devices has become part of current children's art education activities. Today's release of pen-equipped mobile devices and smart tablet PC's allows users to painting and coloring with digital devices. Today, art content for children is downloaded and can be educated at any time as an application. However, coloring games that give children the effect of art education are extremely rare, and the content elements in the games are similar to all games and lack the ability to express themselves. The study recognizes the importance of developing coloring game content for children's art education that can help children's coloring activities and improve creativity and imagination, and focuses on the direction and elements of developing children's coloring game content using smart mobile devices that fit digital coloring functions.

Recently, devices that help the general public's urination activity have been developed, but products that take into account the user's urination habits, device functions, and user accessibility are still insufficient. This study conducted a usability evaluation to find user satisfaction and improvement points of products based on smart automatic urine disposer that have convergence and complex functions such as automatic suction functions. There are 21 indicators used in usability evaluation, and were developed based on safety, operability, and satisfaction. As a result, functional satisfaction was high, but in terms of design, problems to be improved such as handles were presented. Therefore, through this study, it was found that the satisfaction of the automatic urine disposer in terms of performance cannot be representative of the product, and the importance of developing usability evaluation index to find product problems.

Robot technology has become a crucial part of today's business operation. In fact, more manufacturing firms have been utilizing robot technology in order to increase operational efficiency and productivity. Thus, this study develops the research model investigating firms; behavior for process innovation with intelligent robot. Three categories - Technical, Entrepreneur, and Environmental characteristic - are proposed in the research model as determinants of process innovation. These three characteristics include six variables(Perceived Direct Usefulness, Perceived Indirect Usefulness, Innovation, Risk Senstivity, Perceived Industry Pressure, and Perceived Government Pressure) as influencing factors on process innovation. The data from 77 employee at manufacturing firms were analyzed to test proposed hypotheses. The results reveal that all variables with exception of Perceived Government Pressure have a significant influence on process innovation. Based on the study results, theoretical and practical implications for process innovation with intelligent robot technology are discussed.

IoT(Internet of Things) 기기를 활용하는 분야가 증가함에 따라 스마트 팩토리, 스마트 그리드 등 융합환경이 발전되었으며, 융합환경이 상호연결되는 IoBE(Internet of Things Blended Environment)가 조성되고 있다. 그러나, IoBE 구성요소가 복잡해짐에 따라 공격 표면이 증가하고, 기존에 알려진 보안위협이 융·복합되어 새로운 형태의 보안위협인 복합위협(BT, Blended Threat)이 발생할 수 있다. BT는 다양한 보안위협이 복합적으로 연계되어 발생함에 따라 예측하여 대응하기에 기존 보안위협보다 상대적으로 어려우며, 이에 대응방안 간의 조합을 통해 보안위협에 유동적으로 대응하는 동적 보안 프레임워크가 필요하다. 따라서, 본 논문에서는 BT에 대한 대응방안 동적 조합 프레임워크를 제안한다.

Due to globalization, more foreign-owned small businesses have been joining the South Korean economy. In order to better support the growth, this study's purpose is to identify foreign entrepreneur demographics and company information as well as entrepreneurial motivations and perceived success factors. To fulfill these goals, a survey of 98 immigrant entrepreneurs from 31 countries doing business within the local Korean market was conducted. The results show that most foreign-owned small businesses are service-oriented and primarily started for intrinsic reasons. It was also identified that the perceived business success determinants that the government can most directly affect are skills-based, rather than infrastructure or financially oriented. Furthermore, top issues include unreliable employees, language barrier and too much competition. The findings of this study are particularly relevant to both academics and policy makers alike because almost no prior foreign entrepreneur-focused research has been conducted in Korea.
