The purpose of this study is to investigate the factors on the characteristics of youth gambling addiction to develop the youth gambling prevention program. The data was collected by using questionnaire, from Oct 2010 to Dec 2011. Of the 2,400 surveys distributed, 2,301 were collected and 2,286 of those were used for analysis after eliminating 15 with insufficient responses. The major findings of this study can be summarized as follows. First, there were some differences on the future gambling intention and the internet addiction by gender, grade, pocket money, experience in the illegal gambling site visits and gambling experience. Students who experience in the illegal gambling site visits were represented relatively higher on the future gambling intention and the internet addiction. Second, the overall experience in the illegal gambling site visits is 6.9%, while 23.2% of the total respondents were found to be the experience of gambling. Third, the future gambling intention, irrational gambling beliefs and the internet addiction were found have positive correlation with each other.

Internet of Things (IoT) is the paradigm of network of Internet-connected things as objects that constantly sense the physical world and share the data for further processing. At the core of IoT lies the early technology of radio frequency identification (RFID), which provides accurate location tracking of real-world objects. With its small size and convenience, RFID tags can be attached to everyday items such as books, clothes, furniture and the like as well as to animals, plants, and even humans. This phenomenon is the beginning of new applications and services for the industry and consumer market. IoT is regarded as a fourth industrial revolution because of its massive coverage of services around the world from smart homes to artificial intelligence-enabled smart driving cars, Internet-enabled medical equipment, etc. It is estimated that there will be several dozens of billions of IoT devices ready and operating until 2020 around the world. Despite the growing statistics, however, IoT has security vulnerabilities that must be addressed appropriately to avoid causing damage in the future. As such, we mention some fields of study as a future topic at the end of the survey. Consequently, in this comprehensive survey of IoT, we will cover the architecture of IoT with various layered models, security characteristics, potential applications, and related supporting technologies of IoT such as 5G, MEC, cloud, WSN, etc., including the economic perspective of IoT and its future directions.

본 논문은 이동 환경 위주의 미래 인터넷 환경을 위해 제안된 Mobile Oriented Future Internet (MOFI) 구조에 대하여 OpenFlow 기반 구현 이슈와 KOREN 실험망을 이용한 성능 분석을 논의한다. MOFI 구조는 호스트 식별자(host identifier)와 지역 위치자(local locator) 사용, 데이터 전달을 위한 Query 우선의 데이터 전달(Query-First Data Delivery), 식별자와 위치자간 분산형 매핑 시스템(Distributed Mapping System)을 특징으로 한다. 기존 MOFI 연구에서는 intra-domain 이동성 지원을 위해 6-to-4 터널링 기법 및 리눅스 플랫폼을 활용한 구현 방식을 제안하고 실험실 테스트베드에서 성능분석을 수행하였다. 한편, 본 논문에서는 inter-domain 이동성 지원을 위한 세부 절차를 논의하고 Click Modular Router와 OpenFlow 플랫폼을 활용한 MOFI 구현 방식을 제안한다. 나아가, 실제 KOREN 실험망을 활용한 성능 실험을 통해 MOFI 구조와 기존 이동성 제어 방식인 Proxy Mobile IP (PMIP) 기법을 비교한다. 실험 결과, 이동성 제어를 위한 시그널링 지연 시간 및 처리되는 메시지 수 측면에서 MOFI 구조가 기존 PMIP 이동성 제어 기법에 비하여 더 좋은 성능을 보이고 있음을 확인하였다.

The purpose of this study was to investigate the discriminative factors of on-line consumer satisfaction. Data were obtained from an online questionnaire survey with 1089 online shoppers who had the experience of either purchasing or visiting a fashion on-line shopping mall from the panel of an online survey agency(www.inr.co.kr) and 1049 responses were analyzed. For analysis of data, descriptive analysis, Cronbach's ${\alpha}$, $\chi$$^2$-test, one-wav ANOVA, Ducan test and stepwise regression analysis were applied. The results of this study were as follows: Firstly as a result of differences of purchasing experience and future purchasing intention via internet, 4 consumer groups were generated: internet patronizing group, trial and unsatisfied experience group, future purchasing intention group, and internet carelessness group. Secondly each group differences was found in demographic variables such as age, marital status, income and employment status. Croup differences were also found in personal, product, and store variables except tangibility. According to consumer groups, different factors were directly impact on consumer satisfaction.

The purpose of this study was to investigate the ways and possibility of on-line environmental education(EE) for a sustainable future. For the purpose, the researchers reviewed and analyzed 22 Korean and 41 foreign Internet sites related EE. Then, the researchers selected five Internet sites in Korea, U.S.A., UK, New Zealand, and Australia. Researchers analyzed these five sites in depth, specially in the aspect of the education for a sustainable future/development. This analysis indicated that 'The Globe Programme'(UK) and 'Global Education'(Australia) sites contain more contents and activities related sustainable future/development then other three sites. On the basis of analysis, the researchers offered several recommendations for on-line EE for a sustainable future.
