If a digital signage system is operated in PC mounted in the Window OS then the implementing price is very high. For resolving this problem, we used the Smartphone mounted in ARM Cortex family of multi-core processor-based mobile platform. We developed a low-power low-cost digital signage system and a remote convergence content management program based on web server. This convergence system manages advertising content to a remote control device anywhere using remote control technology. This system is one integrated system with display and is a low-power consumed and is developed in very efficient hardware interface. And condition sensors(intensity of illumination, temperature, weather, GPS etc) is equipped in the developed system. Automatic contents builder and Context-aware SMIL module is also implemented in the convergence system. We achieved over 50% power savings comparing with conventional Window OS system and 16 points multi-touch in our system.

The P2P technology is becoming a technology for receiving a service, such as the latest YouTube and Facebook. P2P technology can be easily downloaded to a large amount of multimedia content over a distributed environment. However, pictures, music, a large amount of multimedia content such as videos each user is unable to manage the content management operating smoothly because, Song communication processing overhead caused when the reception is likely to remain the problem. In this paper, we propose a convergence content management technique that provides a low communication overhead of the frequency of use of the convergence content when trying to provide a large amount of convergence content to users in a distributed environment. Our method can be used to select the appropriate frequency is high among the shared content on the P2P multimedia environments that are distributed across a frequency of use of the convergence content and provides the service. Experimental evaluation proposed method, the convergence content browsing speed than conventional techniques improved communication about 13.3% and reduced overhead to about 9.5%.

This study was purposed to figure out current situation of part of 273 middle-school girls' dietary behavior and problems, then provide baseline data which helps to develop desirable eating behavior and life style. It appeared that suitable amount of eating(F=6.378, p=.002), degree of unbalanced diet(F=3.542, p=.030), Nutrients intake(F=6.780, p=.001), and life style(F=4.291, p=.015) differs between groups depending on student's subjective physical health status. It turned up that perceived physical health status is related to moderate amount of eating, degree of unbalanced diet, and Nutrients intake(p<0.05). As a results, in the period of adolescent which is a rapid growth period, there should be a systematic and endurable practice of right eating behavior, foods for formation of lifestyle, and convergence education in health area.

The purpose of study is to enhance the convergence effects of cyber lecture for university students. The results were derived through the comparison and verification of recognition levels before and after cyber lectures. The study material was a questionnaire composed of 15 questions divided into five areas; usefulness, enjoyment, academic relevance, social intention and usage intention. The recognition levels significantly improved after learning in five areas with particularly large improvements in enjoyment and academic relevance. The recognition levels significantly improved in the five areas(p<.001). With regard to changes in recognition levels by major, social science majors showed significant improvements in usage intentions after learning. Cyber lectures for university students were proved to be generally convergence effective.

The purpose of this study is to analyze the effect of social capital include networks, trust, norms, and participation on depression in the elderly in the era of convergence. The subjects of this study were 302 senior citizens aged 65 and over who are living in Seoul and Gyeonggi Province. The results are follows. Depression was more severe in the elderly with lower level of education, no religion, and lower social capital including networks and norms. In this study, social networks were found to be the most important contributor to depression. In order to alleviate depression in the elderly through this study, efforts to activate and expand the network of the entire society are required. In other words, it is necessary to expand the activity space of local community, develop programs for various convergence contents, and expand education programs for the elderly in order to vitalize the network of the elderly.

If the software is developed to analyze the speech disorder, the application of various converged areas will be very high. This paper implements the user-friendly program based on CART(Classification and regression trees) analysis to distinguish between normal and pathological voices utilizing combination of the acoustical and HOS(Higher-order statistics) parameters. It means convergence between medical information and signal processing. Then the acoustical parameters are Jitter(%) and Shimmer(%). The proposed HOS parameters are means and variances of skewness(MOS and VOS) and kurtosis(MOK and VOK). Database consist of 53 normal and 173 pathological voices distributed by Kay Elemetrics. When the acoustical and proposed parameters together are used to generate the decision tree, the average accuracy is 83.11%. Finally, we developed a program with more user-friendly interface and frameworks.

사람은 노화가 진행됨에 따라 기억력, 지능, 언어, 운동 기능 등의 인지능력이 저하되므로 대상 노인에 특성에 맞는 적절한 재활치료 방법을 적용해야 한다. 체감형 3D 인지시스템은 가상현실을 기반으로 하고 인지능력 향상을 위한 컨텐츠를 적용하여 환자의 특성에 맞는 의료 활동을 수행할 수 있다. 특히 원예 컨텐츠는 노인들의 참여도를 높일 수 있고 인지능력 향상과 우울증 감소에 도움이 된다. 이러한 가상현실 시스템은 위치인식, 동작인식, 디스플레이 등의 하드웨어 장치들을 이용하여 구현 가능하다. 본 논문에서는 노화에 따른 인지기능 저하와 종류와 특징을 분석하고 관련 재활치료 방법을 조사하였다. 또한 체감형 3D 인지시스템을 구성하는 모듈과 재활치료에 적합한 가상현실 컨텐츠를 제안하였다.

First broadcasted in 1979's and until today very popular in the Original title video content Mobil Suit GUNDAM, it has difference to existing other two-way race other robot animation. According to director Tomino Yoshiyuki animation Gundam has an elements of drama. It's explain imply all untruth reality contents. The content of Japanese animation, GUNDAM beyond its wide range of industries around the world, further developed and expanded, and further is referred to as GUNDAM culture. Academic culture in terms of the five elements that make up culture (technology, values, social relations, language, and material) around the content analysis of GUNDAM. As a result, the five cultures of each of the elements that conflict with sufficient information and are believed to be worth.

노화가 시작되면 체력이 저하되어 면역기능이 떨어져 쉽게 병에 걸리고 환경에 대한 적응력이 떨어진다. 특히 60세 이상이 되면 근육 양과 근력이 급격히 가속화되어 신체적으로 약화되기 시작한다. 노화는 자연스럽게 진행되지만 꾸준한 운동을 통해 근력 저하 속도를 늦출 수 있다. 근력 증강을 위한 다양한 기기 개발에도 불구하고 노인들이 사용하는데 어려움이 있다. 특히 노인 신체적 특성에 맞는 운동기기 개발이 절실하며, 노인의 흥미를 유발시켜 자발적 참여를 유도하는 환경이 제공되어야 한다. 가상현실 기술은 실재하지 않거나 먼 거리에 있는 환경을 가상세계로 생성시켜서, 인간의 오감을 각종 인터페이스 장치를 통해 신호를 전달하여 가상의 현실 환경에 실재하고 있다고 느끼도록 만들어 주고, 가상세계와 상호작용을 통해 의료 진단, 치료, 재활 등에 유용한 도구 및 환경을 제공한다. 이러한 가상현실 기술의 특성 때문에 노인의 운동 참여와 운동 효과를 극대화 할 수 있다. 본 논문에서는 근력의 특성을 분석하고 노화와 근력과의 관계를 조사하고, 상지근력 증강 운동기와 해당 가상현실 컨텐츠 그리고 관련 컨텐츠 개발 동향에 대해 제시하고자 한다.

This study investigated the perception of beauty-agriculture convergence industry for businesses in senary industries in Jeju Special Self-governing Province. Currently this area is in the stage right before the suggestion of a convergence-based win-win industrial development model. The ultimate goal is to provide basic data to beauty-agriculture convergence industries. Agricultural products are used as main ingredients in the cosmetics industry and recently, farmers have been focusing on certain areas of the beauty industry, such as the internal production of beauty products and the attraction of customers. According to a comparative analysis on the beauty-agriculture convergence industry between employees and non-employees, a statistically significant difference was found in the following: Possibility of creating high profits, personal interest in the beauty industry and the possibility of utilizing natural resources. In terms of the reasons for beauty-agriculture convergence industry development potential such as added value, leading industry, product competitiveness, aesthetic lifestyle and market size, as well, a significant difference was found. In the perception of the necessity of government supports such as financing, facilities, technology, education and PR marketing, no significant difference was observed. Since creative and diverse contents are needed for beauty-agriculture convergence, high-quality technical support and continuous education are essential. Therefore, diverse government supports including funds and facilities are needed.
