N-스크린 환경에서 방송사들을 포함한 사업자들은 온라인을 통해TV 프로그램을 시청자들에게 제공하고 있다. 사업자들은 N-스크린 서비스를 운영하면서 광고를 통해 수익을 창출하고 있는데, 모바일 이용이 활성화 되면서 N-스크린 광고 시장 규모도 증가하고 있다. 모바일 환경에서는 화면 크기의 제약으로 인해 기존의 이미지, 베너 형태의 광고 보다 동영상 광고방식이 유리하여 이에 대한 수요가 높은데, N-스크린 환경에서 다양한 화면 사이즈를 가진 기기에 동영상 광고를 제공하기 위해서는 광고 소재 관리가 필수적이다. 또한 온라인 광고 제공에 관여하는 광고주, 광고 대행사, 플랫폼 사, 매체 사 간에 협업이 가능한 시스템 개발이 요구된다. 본 논문에서는 N-스크린 환경에서 동영상 광고를 효율적으로 제공하고 운영하기 위한 시스템을 제안한다.

A new type of passive samplers were designed and produced by authors. After evaluating the quality of activated carbon by measuring recovery rate of organic vapors and steadiness of sampling rate, activated carbon with 30 - 35 mesh produced by Company S in Korea was selected. In each passive sampler, an amount of 400 mg of the activated carbon was filled in 25-mm cassette and covered by fixed screen (or wire screen with 100 mesh). In addition to the fixed screen, a wind screen (or wire screen with 300 mesh) was also attached at outer face. The sampling rate of the new Korean passive samplers was estimated Conclusions obtained in the study are as follows. 1. Sampling rates of the newly developed Korean passive samplers were affected by sampling time. For n-hexane, sampling rates of 15- and 60-minute samples were 70.92 and 37.45 ml/min, respectively. Sampling rate of both 200- and 450-minute samples was 25.96 ml/min. It is concluded that, when passive samplers are used for measuring organic vapors, samples be collected longer than 60 minutes. 2. Sampling rate of the passive samplers was also affected by airborne concentration of organic vapors. Lower sampling rates were determined at level of 1/2 threshold limit values (TLVs) recommended by the American Conference of Governmental Industrial Hygienists (ACGIH). It is recommended that sampling rate of the passive samplers be obtained at site by measuring concentrations using both the NIOSH Method and passive samplers simultaneously. 3. When the passive samplers, which collected organic vapors, were exposed to clean air for five hours, there was no significant loss of organic vapors due to reverse diffusion. 4. When samples were stored at room temperature ($21.8{\pm}0.7^{\circ}C$) and refrigerator ($3.8{\pm}0.7^{\circ}C$), there was no significant difference in the accuracy of results. For trichloroethylene and n-hexane, accuracies were within 25 % at both temperatures until seven days. However, poor accuracy exceeding 25 % was indicated in toluene from the first day. It is recommended that samples be stored at freezing temperature below $0^{\circ}C$. 5. Sampling efficiency was significantly affected by direction of the passive samplers. Results of samplers facing wind and down, respectively, were compared. Lower amount of organic vapors were collected when the sampler was oriented down. It is recommended that, when air velocity is low in plants, the passive samplers be oriented to the wind. However, when air velocity is high, the passive samplers be oriented down.

Since 1992, Philips has been developing polymer OLEDs resulting in a first commercial monochrome display just 10 years later. Philips is now focusing on the technology development required to mass-produce full-color polymer OLDE displays, based on passive and active-matrix addressing. High precision inkjet printing has been chosen as the deposition technology for the OLED material. In this paper, we give an overview of the activities of Philips in the area of mobile OLED applications and explore the route towards large screen OLED television.

In the N-Screen environment, HTML5 standard-based content development is inevitable. However, it is still passive the development of HTML5 manipulation type contents due to high development cost and insufficient infrastructure. Therefor we propose an efficient contents development model by convergence multimedia contents (such as video and audio) with HTML5 documents that can implement dynamic manipulation for user interaction. The proposed model is designed to divide the multimedia and iframe areas in the HTML5 layout page included the player for integrated contents control. Interactive HTML5 documents are divided into screen units and provided through iframe. The integrated control player composed based on the HTML5
