The purpose of this study was to identify the effects of Neurofeedback(NF), Cranio-Sacral Therapy(CST) and Combine Therapy(CT) in middle aged women through their experiences after participating these therapies. The participants were 53 middle aged women who lived in S city, 17 in the NF group, 17 in the CST and 19 in the CT, for 10 weeks from October to December, 2007. The NF group had 30 sessions, the CST group had 10 sessions and the CT group had 30 sessions of NF training after 10 sessions of CST. The data was collected from daily chart by self reporting their experiences during sessions. Collected data was analyzed by content analysis. From raw data, 37 items of NF, 91 items of CST and 110 items of CT were extracted in the content analysis. Similar items were gathered to 22 attributes of NF, 63 of CST and 68 of CT. These attributes were categorized into 9 higher attributes. The dominant attributes of NF were doziness during the training, mental comfort, lightening of physical and mental condition. Mental and physical comfort, improvement of sleep, healthy condition, crying were the dominant of CST. Also mental and physical comfort, lightening of physical condition, improvement of sleep, tear were the dominant of CT. According to the results of this study NF, CST and CT were very effective on physical and psychological relaxation. Therefore it is recommended that these NF, CST and CT be used as a complementary and alternative medicine(CAM) in middle aged women.

This study focused on smartphone adoption of foreign students who are studying in Korea in digital media era. Smartphone is not only new media but also social media. Based on former research, factor for smartphone adoption of foreign students will be analyzed. Based on TAM theory technological attribute, individual attribute and social attribute were taken out as independent variables. Perceived ease of use and perceived usefulness are applied as mediator variables. In conclusion, some hypotheses for example service quality and individual attribute are rejected as variables which influence positively to mediator variable perceived easy of use. For the next research more various variables and nationwide sampling will be needed.

The purpose of this study is to investigate the influence of guarantee advertising by three sports stars (Jisung Park, Doori Cha, and Tahwan Park) working for famous sport brand names such as Nike, Adidas, and Fila on the intention of purchasing. In the study, total 240 people of all ages but those who are under twenty are chosen to conduct a survey. The results of investigation is the followings. First, with the respect of gender and age there are statistically meaningful differences between sports stars' guarantee advertising and consumers' intention of purchasing sporting goods that result from demographical elements. Second, how the guarantee advertising of sports stars have an influence on consumer's intention of purchasing products results in the three sports stars in a different way. As for Jisung Park, the result represents that his athlete characteristics such as expertise, creditability and similarity have to do with consumers' intention of purchasing goods most. Third, as for Doori Cha, the result identifies that his creditability and similarity plays an important role for the consumers' intention of purchasing. Forth, as for Tahwan Park, similarity has some meaningful influence on the sport consumer's intention of purchasing. The fact that similarity plays an important role in common for the consumers' intention of purchasing is noteworthy to the researchers relating to the advertisement area.

Many countries, especially ICT powers, are supporting IoT-based technology at a national level and this technology is actively being researched in the businesses and research institutes in an aim to develop technology and create an ecosystem. Roads in the Seoul city are building public facilities based on IoT to provide various services and conveniences for the users. However, for the full-fledged introduction and development of IoT, there are many cases where infringement on security and privacy and threat for life and safety happen. Also, as the IoT environment includes various environment technologies such as the existing sensor network, heterogeneous communication network, and devices optimized for the IoT environment, it inherits the existing security threat and various attack techniques. This paper researches the attribute based encryption technology for safe communication in the IoT environment. The data collected from the device is transmitted utilizing the attribute based encryption and by designing the key generation protocol, grades and authorities for the device and users are identified to transmit safe messages.

The technology of virtual environments has been developed with better-quality appearance on a computer display in mind, but without consideration for objects' precise measurements in physical units. With the increased application of computer graphics in a variety of areas, there is a need for precise measurement functionality in addition to visualization. This paper describes the definition of physical properties using measurement units for X3D based virtual objects, to provide their precise physical information in virtual environments. To this end, we have included the physical property node in the X3D specification. The physical measurement units, such as length, mass, time, temperature, etc., are based on SI units (International System of Units).

본 논문에서는 가상환경 국제 표준인 SEDRIS 기반의 가상현실 브라우저 개발에 대해 기술한다. 이 가상현실 브라우저는 가상환경을 구성하는 모든 객체들의 정보를 포함하고 있는 데이터의 구조를 가시화 하는 트리 뷰와 객체들의 3차원 모습을 표현하고 대화형 인터페이스에서 제어할 수 있는 렌더링 뷰로 구성되어 있다. 이 브라우저는 기존의 3차원 브라우저에서 다루어 온 가상세계의 가시화 실현의 의미 외에도 실세계를 구성하는 모든 객체들의 속성을 척도의 단위까지 묘사할 수 있는 국제적으로 표준화된 속성 기술 방법을 근거로 한다는 점에서 장점을 가진다.

C++는 C의 장점을 가지고 있으면서 객체지향적 요소를 포함하고 있어 현재 객체지향적 소프트웨어 개발에 가장 많이 사용되어지는 언어 중에 하나이다. 본 고에서는 원자력 발전소 제어시스템과 같은 안전 시스템 개발에 사용될 언어가 보장해야할 속성에 대하여 정의하고 이러한 속성들을 C++는 어떻게 지원할 수 있는 가에 대하여 기술하였다. 80년 이후에 소개된 객체지향 기술이 계속적으로 발전하고 소프트웨어 개발에 많은 장점을 제공하고 있기 때문에 많은 분야의 소프트웨어 개발에 적용되어지고 있다. 따라서 safety-critical 시스템과 같이 고신뢰성과 안정성이 요구되는 시스템 개발에도 적용되어 진다면 소프트웨어 개발 생산성에 많은 도움이 될 것이다.

우리나라 여행업은 1989년 이후 해외여행 전면 자유화 실시 이후 다양한 유통채널을 통해 양적 질적 발전을 이루어왔다. 그러나, 학문적 관점에서는 다양화된 유통채널에 대한 다양한 접근은 아직까지 부족한 실정이었다. 따라서, 본 연구에서는 선행연구 검토를 통한 다각적인 접근을 통해 서비스 기업의 상품 선택속성에 관한 이론적 토대를 제시하는 데 일조하는 데 연구목적이 있다.

An IPTV (Internet Protocol Television) technology is the new convergence technology of the telecommunication and broadcasting which provides various bidirectional TV services. To provide these services only to legal subscribers, mutual authentication between set-top box connected with TV set and the smart card owned by a subscriber is needed. In this paper, we propose an attribute-based mutual authentication scheme that only someone who is satisfied with some attributes, such as titles or departments, can access the contents provided by the IPTV service in an organization. We also show that the proposed scheme is secure. Our proposed scheme has a virtue that user can access various services, provided by an organization where he/she belongs to, according to their attributes with only one time registration. As far as we know, this is the first attribute-based authentication scheme which can be applied to any organizations in IPTV environments.
