This paper proposes an intelligent technique for data sharing and event transition among personal devices including smart phones, laptops, and desktops. We implemented the PES (Personal Event Service) system that proactively executes appropriate tasks across multiple devices without explicit user requests by sharing the data used by the user and recognizing user intention based on the observed actions of the user for specific devices. The client module of PES installed on each device monitors the user actions and recognizes the intention of the user. The server provides data sharing and maintenance for clients. The connection between client and server is established by Java RMI (Remote Method Invocation). A series of experiments were performed to evaluate user satisfaction and system accuracy, and the results showed that the PES system can proactively provide appropriate, personalized services with a high degree of satisfaction to the user in an effective and efficient manner.

최근 스마트 디바이스의 증가에 따라 개인이 휴대하는 장치가 증가하고 있으며, 대부분의 스마트 디바이스에는 블루투스가 기본사양으로 탑재되고 있다. 그러나 블루투스 장치의 연결 제한으로 다중연결을 활용한 서비스 제공은 미흡한 상태이며, 다중연결이 가능하더라도 설정된 장치가 모두 접속되어야 데이터 통신이 가능한 문제점이 존재한다. 본 논문에서는 이러한 문제점을 해결하기 위한 방안으로 AT Command를 활용한 TDM(time division multiplexing) 방식의 다중연결 알고리즘을 제안하였다. 시뮬레이션을 통해 다수의 장치가 실시간 접속 및 데이터 전송이 가능하다는 것을 확인하였다.

Recently, with the proliferation of smart phones and mobile devices and the increase in the speed of mobile Internet, IT services are increasingly used in smart phones and mobile devices in a different way from the past. That is, a cloud service that downloads and uses data stored in the server in real time is expanding, and as a result, the security due to the continuous Internet connection of the user becomes a problem. In this study, we analyzed the relationship between factors affecting the continuous use of personal cloud service by using technology acceptance model. In addition to the technology acceptance model, confidentiality, privacy, accessibility, innovation, and self-efficacy were extracted from the existing research with emphasis on the characteristics of the cloud service and security factors. Moreover, the difference of intention to use among genders was verified through structural equation modeling with survey data from 262 personal cloud service users.

Currently, web-based online games is becoming popular in supporting learning process due to their effective and efficient tool. However, online games have lack of security aspect, in particular due to increase in the number of personal information leakage. Since the data are transmitted over insecure channel, it will be vulnerable of being intercepted by attackers who want to exploit user's identity. This paper aims to propose an online web-based educational game, Vidyanusa which allows the students to register their personal information using a unique code, a user name and a password. It manages the users according to their schools, subject teachers and class levels. In addition, by adopting a unique code, the confidentiality of the user identity can be kept away from attackers. Moreover, in order to provide a secure data communication between client and server, Secure Socket Layer (SSL) protocol is adopted. The performance of the system after implementing SSL protocol is examined by loading a number of requests for various users. From the experiment result, it can be concluded that the SSL protocol can be applied to web-based educational system in order to offer security services and reliable connection.

This research explores diachronic fashion design trends through a structure analysis of a connection network based on fashion show concepts implemented by modern fashion designers from S/S 2009 to F/W 2013. The findings from this research are as follows. First, four categories affect the inspiration and thinking of design: the experience of the designer, social atmosphere and phenomena, natural sensitivity (or formative characteristics of natural objects), and the influence and quality of other fields. Second, in cases where the designers' experiences influenced design inspiration and thinking, designers express personal memories with keywords like high school, grandmother's closet, prom, beauty and the beast, heritage, past, and reminiscence through design elements such as lines, silhouettes, materials, and colors. Third, the representative example of the social atmosphere and phenomena that influenced design inspiration and thinking was the 2008 Global Financial Crisis that reflected the social climate through design concepts of keywords such as Recession, Black, Economy, US, Depression, Gray, Dark Age, White and New York. Fourth, inspired by nature and the formative characteristics in design, the designers employed ornamental elements to collections and design concepts that focused on nature words connected to light, sun, wild, dirt, rock, moss, and trees. Fifth, the designers took their ideas from different fields of personal interest in the arts, science and humanities (sports, architecture, sculpture, painting, and literature) that were decisive in determining materials, design colors and silhouettes. The theme of architecture was analyzed as a central element that had an ongoing impact on the concepts of designers.

Malinowski′s "Theory of Culture Change" which means an acculturation is the change′s elements of the dress and its ornaments. It is remarkable that the dress and personal adornments of Korean women after August 15, 1945 has great change from the traditional dress of the thousands years. Through the Liveration on August 15, 1945, American military government and the establishment of the Korean government, American democracy has brought many changes on Korean society. Advancement of education, an society with developed economic life, and introduction of scientific skill have influenced on the women′s way of thinking and a style of behavior and the view of value. The acculturation, the supply of mass communication, introduction of new institution and the reorganization of the old institution, the change of the economic situation, the change of the educational system, the change of the point of value, the development of scientific skill have greatly influenced on the dress and personal adornments. Modern dress and personal adornments of Korean women has the following developing procedure. The Liberation from Japan on the 15th, of August, 1945, the stationing of American Soldiers during hte Koran War, returning of the oversea′s brethern, and the mass communication have the direct and indirect contact with western civilization, and bring the occasion of development of the modern dress of Korean women. The increase of mass communication, such as radio, TV, newspaper, magazines and the frequent fashion shows showed fine design and practical western style dress to the women. This was the real beginning of the western style dress in Korea.
