Due to multiple information sources, external information search(EIS) is the key issue on smart tourism environments. EIS is more important on experiential goods such as exhibition and convention. Despite the increasing importance of EIS, very little is known about what is the more effective information source in this area. In this paper, we attempt to examine the relations of satisfaction and between both online and offline information. This research analyzes an empirical model including EIS, affective involvement, perceived usefulness, satisfaction to student visitors on exhibition experience. Hence, six hypotheses are developed to test the relations of EIS and satisfaction using the mediating effects of affective involvement. Specifically, we developed a research model by employing the Uses and Gratification(U&G) framework and tested it to understand how student visitors' involvement and satisfaction might be changed according to EIS. Survey data was collected from 203 student visitors on "2014 Expo KCCE" was used to test the model using structural equation modeling. The implications of our empirical findings for both research and practice are discussed.

In this paper, we present the architecture of graphics processor and its instruction format for the mobile device. In addition, we introduce tile shader data structure for the on/off-line compilation based on the OpenGL ES 2.0 and a new optimization method based on the ILP(Instruction-Level Parallelism). This paper shows where a processor with the sane core clock is being used, the shader instruction resulted from the compile structure and method in this paper is approximately 1.5 to 2 times faster than a code based on the single instruction.

The usability of QRcode as a replacement of the Barcode has been increasing. As the QRcode can be saved much information than Barcode, the QRcode has various application areas. In these days we can see the quadrangular box in everywhere. In this paper we introduce an example of application areas of the QRcode, which the system save the mileage information on the Android smartphone. Our proposed system help the small markets or traditional markets which don't have enough fund to construct mileage system.

Purpose - This study reestablished the concept of mixed emotions experienced in online and offline shopping environments, and structuralized emotional responses which manifest mixed emotions in each channel, and developed a method of measuring overall mixed emotions in consideration of the asymmetry of emotions. Design/methodology/approach - This study conducted a focus in-depth interview based on phenomenological research and exploratory preliminary survey using questionnaires. In addition, a survey was conducted as a quantitative survey. Findings - Qualitative and quantitative researches were conducted to derive major emotional responses items which manifest mixed emotions in online and offline shopping environments and determine differential emotional structure in each channel. As a result, it was confirmed that mixed emotions consisted of 5 factors in each channel and 21 emotional responses. In addition, a method of measuring overall mixed emotions considering the asymmetric of emotions was developed to prove the difference in behavioral responses. Research implications or Originality - This study is meaningful in that it helps companies efficiently manage and understand customer responses to their products by classifying and systemizing the emotional responses experienced by consumers in online and offline purchase and consumption situations according to the purchase environment.

현재 글로벌 환경은 빠르게 변화하는 4차 산업혁명의 도래로 산업구조는 물론 사회경제 전반에 걸쳐 거대한 변화에 직면하고 있으며, 미래에 대한 불확실성이 깊어져서 이에 대한 빠른 대응이 필요한 시대가 되었다. 또한 4차 산업의 주축인 디지털 혁명과 코로나 19 팬데믹 사태로 변화의 가속화가 진행되면서 이러한 변화에 얼마나 신속하게 대응하느냐가 생존과 성장의 핵심이 되었다. 본 연구는 기존의 선행 문헌연구를 바탕으로 기술기반 창업기업의 창업가 역량과 기업성과 간의 인과관계를 통합적으로 규명하는 것을 목적으로, 불확실한 경제 상황 속에서 기술창업과 창업가 역량의 중요성을 인식하여 기업성과에 영향을 주는 요소를 분석하고자 한다. 이와 같은 목적을 달성하기 위하여 창업가 역량을 독립변수로 하고, 정부지원활용을 매개로, 창업가 일반적 특성(업종, 업력, 창업경험, 특허보유, CTO인력보유 여부 등)을 조절변수로 하여 기업성과에 미치는 영향에 대한 연구모형을 설정하였다. 연구모형 검증을 위해 대전 대구 지역의 연구개발특구, 산업기술단지, 첨단산업단지, 창업보육센터, 테크노파크등, 기술집접화시설에 입주해 있는 217개 기업을 대상으로 온 오프라인 방식의 설문조사를 실시하였다.
