  • Social media marketing have drawn substantial attention in business and academia. This study examines the impact of social media marketing on purchase intention of consumer in South Korea and Pakistan. The research background rests on literature of social media, social media marketing, electronic word of mouth and social media advertisement. Descriptive research method is adopted for the purpose of this study. The findings indicated that South Korean users have higher intention to purchase products through social media platforms as compared to users in Pakistan. The results also show that electronic word of mouth has greater influence on purchase intention as compared to advertisement on social networks. Managerial implications and limitations of the study results were also discussed.

  • 최근 들어 인터넷, 인트라넷을 통해 양질의 동영상 데이터를 네트워크 상으로 실시간 또는 사용자의 요구에 따라 전승해 주는 스트리밍 서비스에 대한 요구가 증가하고 있다. 아울러, 유비쿼터스 환경의 도래와 함께 센싱을 통한 다양한 멀티미디어 서비스의 확장이 이루어지고 있으며, 유/무선 환경에서 사용자의 콘텐트에 대한 요구를 끊김 없이/연속 이동을 통해 볼 수 있는 사용자 맞춤형 서비스가 필요로 되고 있다. 이에 본 논문에서는 센서기기를 연동해서 사용자를 인식하고 양질의 동영상을 사용자의 요구 시점에 이동성을 보장하면서 사용자의 다양한 단말 조건을 인식하여 멀티미디어 서비스를 제공하는 내용을 담고 있다.

  • 본 논문에서는 좌우 해상도가 서로 다른 융합형 3DTV 시스템에서 합성된 3D 영상의 화질을 개선하는 방법인 조건부 대체 알고리듬에 적용하기 위한 비트율 제어기법을 제안한다. 조건부 대체 알고리듬에서는 쿼드트리 형태의 가변크기 블록마다 좌우 영상간의 양안시차 정보를 활용하되, 이 정보의 전송을 위해서 부가적인 대역폭이 요구되기 때문에 전송 대역폭의 상황에 따라 부가 정보의 양을 효율적으로 조절할 필요가 있다. 이를 위해 비용함수를 정의하고 가중치를 적용하여 최적의 모드를 결정하는 방법을 제안한다.

  • In this paper, a MAS information management method is proposed for the WiMedia MAC protocol. WiMedia MAC configures a fully distributed network based on Ad-hoc method. WiMedia devices communicate during Superframe which is a communication unit in WiMedia MAC. Each superframe which consist of 256 MASs is divided into two periods, beacon period and data period. In data period, devices communicate with each other using the received channel access information during the beacon period. Due to only $12{\mu}s$ timing allowance between beacon period and data period, the process of the MAS information management cannot be completed in time if entire process handle by software. Therefore, we propose a novel MAS information management method using hardware module. With our proposed method, a WiMedia device is satisfied with the processing time that is required in WiMedia MAC protocol.

  • This study investigated differences in children's story comprehension as they related to the types of reading media. The participants comprised 62 four-years-olds from two child-care centers located in a middle-income region of Seoul and Gyeonggi Province. In order to control the experience effect, newly developed stories published into two formats of reading media (paperback books and electronic books) were provided to the participants. The results indicated that there were no significant differences in children's story comprehension depending on the types of reading media. Paperback book readers and electronic book readers did not show any significant difference in story comprehension, which consists of recall, recognition and reasoning tasks. As literature pertaining to children's usage of electronic books is limited, the present study offers guidelines for the development of children's reading media and may serve as a useful resource for future studies.

  • This study explored social media use among 50 adolescents attending a public high school in a non-Western community. Adolescents participated in focus group interviews and completed a written self-report survey. Findings revealed that these teenagers use electronic communication forms such as phone texting and social networking sites to connect with friends and family. They show a preference for Facebook, YouTube, and Instagram, do not engage in risky Internet behavior, and acknowledge both positive and negative aspects of electronic communication forms. In addition, their selection of electronic communication forms is dependent upon several factors that include the strength of the relationship and type of discourse exchange. For example, they reserve phone texting and cell use, which are more private communication mediums for family and friends. Electronic communication did not replace face-to-face interactions; rather it complemented and extended those interactions. Findings support existing literature on adolescent social media use and those shared with other collectivist cultural groups.

  • We proposed a novel method to evaluate the magnetic properties of the initial layer and the columnar structure separately for CoCr-based perpendicular recording media. We show that the thickness of the initial layer and the intrinsic magnetocrystalline anisotropy of columnar structure can be quantitatively evaluated using the plotted product of perpendicular anisotropy to magnetic film thickness versus magnetic film thickness ($K_{u{\bot}}^{ex{p.}}$ $\times$ d$_{mag.}$ vs. d$_{mag.}$ plot). Based on the analyses, it is found that: (1) compared with CoCrPtTa media, CoCrPtB media have relatively thin initial layer, and have fine grains with homogeneous columnar structure with c-plane crystallographic orientation; (2) CoCrPtB media can be grown epitaxially on Ru or CoCr/C intermediate layer, and as the result, the magnetic properties of the media within thin thickness region of d$_{mag.}$ $\leq$ 20 nm is significantly improved; (3) the key issue of material investigation for CoCr-based perpendicular recording media will be focused on how to fabricate c-plane-oriented columnar grains well isolated with nonmagnetic substance in epitaxial-growth media, while maintaining the thermal stability of the media.

  • 본 논문은 펌웨어와 인공지능을 이용하여 지형의 사각지대를 이동하며 순찰 및 방범의 목적을 지닌 시스템을 소개하기 위함에 있다. 기존의 보안 시스템은 비상 상황 발생 시 인력이 직접 출동하여 상황을 해결함으로써 날로 증가하는 최저임금을 고려했을 때 이들의 인건비를 감당하기 어렵다는 단점이 있다. [1] 이러한 문제점을 해결하기 위해 앱 개발을 통해 RC카를 제어하는 아두이노와 연결하여 자율주행을 하게끔 하는 시스템을 개발했다. 또한, 라즈베리파이 웹캠을 부착해 실시간으로 현장을 촬영하여 사용자가 웹에만 접속하면 현장을 모두 감시할 수 있도록 시스템을 개발하였고, 단시간 푸리에 변환(STFT)을 통해 얻은 음성 데이터 변환맵을 인공지능 프로세서인 인텔리노에 학습 데이터로 학습시킨 후에 주변 환경에서 비명 소리만 감지할 수 있도록 시스템을 구현하였다. 본 논문에서는 이러한 시스템들이 기존의 인건비 증가에 대한 문제점을 해소할 수 있다고 생각하여 더욱 효율적으로 방범이 가능한 시스템을 소개한다.
