IOT has evolved from the internet for human oriented, therefore our life is more advanced growth smartly. IoT is the network of physical objects or things embedded with electronics, software, sensors and connectivity to enable it to achieve greater value and service by exchanging data with the manufacturer, operator or other connected devices. Until now many researches have been studied for centering keyword for detecting emerging technology of future and scientometric analysis among the papers. This paper propose searching method of emerging technology for the IOT (internet of things) and smart device which are recently interesting area via dynamic analysis for keyword mapping.

This study analysis the global market trends of information security industry expanding its area through the convergence with other technologies. domestic market of information security industry is expected to show a high growth rate, given that the share of the domestic market in the world market is very low, heightened awareness caused by several information accidents, and the expansion of physical information industry's exports. The crucial point to note is the prospect that the domestic market will be led by its product market, but global market will be spearheaded by its service market. Consequently, to overcome current slump, it is need to establish market promotion strategies focused on fostering the information security service market which is higher value added than information security product market.

This study examined the present condition of convention of convention in Korea and the establishment of strategies for the convention marketing. It is defined as establishing a direction of decision-making for the achievement of efficiency in the convention activities and consists of the following steps; firstly, to set up a target market through the analysis of the convention market and the itemization of the market, and then to draw up a budget and adopt a strategy of convention marketing. Based on this plan of convention marketing, I think the 7P strategy variables such as product, price, passage, and promotion, as well as the participant, physical proof, and process of service assembling should be fixed to attain the target market, for the convention industry is a field of service industry.

In this paper, a system that implementation of Biometric System Using RF-ID. We organize a certification system which the security is strengthened, the information is flowed out and the presentation will do the possibility not to be abused. The loss of the credit card and problems which there is many of forgery back are happening. To solve such problems, We organized the system to use after we stored a fingerprint data at RF Card and going through certification necessary formalities. Various research to be related uses this system and is predicted. The development to common use goods will be possible through a certification procedure.

UV curable hard and color coatings were formed on polycarbonate(PC) films. The coating materials were composed of a commercially available end-capped polyester(EB830), diacrylate monomer(HDDA), silicon acrylate, photoinitiator, and organic dye as a coloring agent. The surface properties of coating films were evaluated, and the influences of the compositions of coating materials were investigated. The coating films showed high transmission and good adhesion between coating layer and PC substrate. And the coating films exhibited higher hardness than bare PC film. The coating films with various colors were obtained by wet process, and the clear and color window lenses for mobile phone were prepared successfully.

This study was conducted to determine the smoke component distribution and the relationship between chemical components and physical characteristics of cigarettes. 16 different cigarette brands which were sold in the market were selected for this study. Five kinds of smoke components which have been tar, nicotine, water, carbon monoxide(CO) puff No., and six kinds of physical characteristics which were filter type, leaf weight, filter weight, UPD, EPD, dilution rate were analyzed. The average values in tar, nicotine, water, CO concentration were 6.5 mg/cig. 0.66 mg/cig, 1.12 mg/cig. and 6.32 mg/cig., respectively. The average ratios of nicotine/tar and CO/tar were 0.10, and 1.02 respectively. The distribution of smoke components collected in the cambridge filter and cigarette filter was different. The averages of tar and nicotine removal efficiency by a cigarette filter were 53%, and 48%, respectively. All smoking components were positively correlated with other smoking components. filter types, EPD, and dilution rate were showed high correlation to the changes of smoke components. Especially, dilution rate of cigarette strongly affected on the changes of all smoke components.

Ozone caused the crack on the surface of a rubber article by oxidation of double bond at room temperature. Wax migrates to the surface of a rubber article and makes a physical barrier to prevent process of ozonation. We investigated change of molecular weight distribution of waxes in unfilled NR, SBR, and BR vulcanizates before and after aging at room temperature for 6 months. Migration and evaporation behaviors of wax in a rubber article at ambient conditions help understand a role of wax as an antidegradant and appearance contamination of a rubber article. The relative intensity distribution of n-alkanes of the NR specimen after the aging was shifted to higher molecular weight compared with the relative intensity distribution before the aging, while those of the SBR specimen before and after the aging did not show a big difference.

AF 코팅은 유리나 플라스틱과 같은 기재 표면을 특수 처리하여 지문과 같은 오염물질의 부착방지와 오염물질이 부착되더라도 쉽게 제거 가능하도록 하는 기술이다. 전자, 자동차, 건축, 섬유, 철강분야 등에 활용 가능한 중요기술로 박막의 발수 발유 기능을 부여하는 표면처리 기술이고, 코팅방법에는 진공증착, 스핀코팅, 딥코팅, 플로우 코팅, 스프레이 코팅 등이 있으며, 경화 방법이나 접촉각 등의 특성이 반영된다. 터치패널 등의 지문부착방지 기술은 불소계와 비불소계 재료로 구분할 수 있지만 지문을 쉽게 지울 수 있고, 오염 방지 기능과 내구성이 있으며, 우수한 광학특성을 유지하는 것이 과제라 할 수 있다. 그리고 항균성을 부여하는 기술도 개발되고 있다. 이런 터치패널의 강화유리에 AF 코팅한 제품은 핸드폰 글래스에 처음 적용하면서부터 실생활에 도입이 시작되고 있다. 이러한 AF 코팅을 스퍼터링 법을 이용하여 증착 시켰다. 기존에는 E-beam을 이용한 증착 방식이 주를 이루었지만, 스퍼터링 법을 이용함으로써 박막의 균일화 및 대량생산이 가능해졌다. 따라서 이 연구에서는 기존의 E-beam 방식과 sputtering 공정 중 ion source에 의한 전처리의 유무에 따른 박막의 특성을 비교하였다. 내부식성, 내마모성 시험을 거친 후, 접촉각을 측정하여 알아보았으며, 박막의 건전성 및 균일성은 FE-SEM을 이용하여 관찰하였다. 실험용 장비가 아닌 실제 생산장비인 직경 1,400 파이의 장비를 이용하여 증착하였으며 염수분무 및 내마모 시험 후, 기존 접촉각의 ${\pm}5^{\circ}$ 내외임을 확인 할 수 있었고, 박막의 건전성 또한 뛰어남을 알 수 있었다.

홈 네트워크 환경은 다양한 기기들이 네트워크로 연결되어 사용되는 환경을 이야기 하고, 특별히 AV 네트워크 활용이라고 하는 기기간 저장된 또는 공유 가능한 오디오 비디오 콘텐츠에 대한 활용이 하나의 가전 네트워크 분야의 중요 부분이 되고 있다. 지금까지 고려되는 다양한 시나리오의 홈 네트워크상의 콘텐츠 활용을 위해서는 기기 또는 콘텐츠 종류에 따르는 고정된 접근 절차에 따라서 콘텐츠에 접근하도록 인터페이스가 개발되어 사용되고 있다. 그러나 홈 네트워크 환경은 기존의 가정내 고정형 정보가전 기기와 모바일 기기가 모두 연결되는 상황으로 기존의 고정형 가정기기들로의 구성과 달리 다양한 사용 경로특성을 가진 기기가 연결되게 된다. 이에 본 연구에서는 이런 상호 동질성을 가지기 어려운 정보기기를 사용해야 한 사용자에게는 사용상의 어려움 줄이는 인터페이스를 제안하고자 한다. 이를 위해 본 연구에서는 가정내 구성원들의 제품 및 콘텐츠 사용 특성을 확인하고, 기기와 콘텐츠 고유의 특성을 고려하여, 다양한 접근 경로를 가지는 홈 / 모바일 기기 사용의 사용경험을 모두 수용하면서 새로운 사용자환경인 홈 네트워크 AV 환경하에 학습이 용이하면서 최소한의 물리적인 인터페이스를 가지는 사용자 인터페이스를 제안한다.

Twenty-six food products which are commonly consumed in Korea were classified according to the method of Oldfield et al., based on the physical and rheological properties, and subjected to the measurement of textural characteristics by the General Foods Texturometer. It was found that the measurement conditions, texturometer curves and parameters differed depending on the food group such as gelatinous, heterogeneous gelatinous, fatty emulsion, cellular textured, fibrous, spongy and porous solid food products. Diverse texturometer curves were obtained from the same kinds of food products, especially among the porous solid food products.
