This study examines how the family background and educational aspiration of adolescents affect the usage pattern of internet among adolescents. Recently, the focus of studies on digital divides shifts from the gap in the access to the internet to the difference in usage pattern of internet. Building on these studies, this study deals with the concerns that the difference in usage pattern of internet among adolescents potentially lead to the reproduction of social inequality across the generations. The analysis of the Korean Youth Panel Study reveals that the higher educational attainment and higher income level of parents, the children tend to spend more time in searching with the internet and spend less time in doing the internet game. The level of educational aspiration exerts similar effects on internet use of adolescents. The results also show that the effects of educational apsiration is larger among older adolescents. The implications and limitations of this study are discussed.

The U-Healthcare era has evolved with the development of the Internet of things (IoT) in the early stages of being connected as a society. Already, many changes such as increased well-being and the extension of human life are becoming evident across cultures. Korea entered the growing group of aging societies in 2017, and its silver industry is expected to grow rapidly by adopting the IoT of a super-connected society. In particular, the senior shift phenomenon has resulted in increased interest in the promotion of the health and well-being of the emergent silver generation which, unlike the existing silver generation, is highly active and wields great economic power. This study conducted in-depth interviews to investigate the characteristics of the new silver generation, and to develop the design for a wearable serious game that intends to boost the interest of the elderly in exercise and fitness activities according to their personalized physical training regimes as prescribed by the U-Hospital service. The usage scenario of this wearable serious game for the 'U-silver generation' is derived from social necessity. Medical professionals can utilize this technology to conduct health examinations and to monitor the rehabilitation of senior patients. The elderly can also use this tool to request checkups or to interface with their healthcare providers. The wearable serious game is further aimed at mitigating concerns about the deterioration of the physical functions of the silver generation by applying personalized exercise prescriptions. The present investigation revealed that it is necessary to merge the on / off line community activities to meet the silver generation's daily needs for connection and friendship. Further, the sustainability of the serious game must be enhanced through the inculcation of a sense of accomplishment as a player rises through the levels of the game. The proposed wearable serious game is designed specifically for the silver generation that is inexperienced in using digital devices: simple game rules are applied to a familiar interface grounded on the gourmet travels preferred by the target players to increase usability.

Research studies have shown that phonological awareness focused analogies and anagrams can be used as an effective game-based teaching instruction. However, previous studies used analogies and anagrams as separate instructional tools, especially in EFL-related situations. There has been no vocabulary learning in analogies/anagrams instruction provided, nor has there been usage of an integrated workbook for 'vocabulary learning and analogies/anagrams'. This study examined the effect on learners' vocabulary acquisition scores when a truly phonological awareness integrated 'analogies/anagrams and vocabulary learning' workbook was used as an instructional practice workbook. The results show that the phonological awareness integrated instruction significantly increased learners' vocabulary acquisition scores among 40 college students with minimal or basic level of English proficiency.

This research focus on the economic activity as consumer and producer traits of future customers in the convergence age. We assess level of convergence for digital devices and services respectively by questionnaire survey and interview for 14 professions. And then, for evaluating convergence level and usage of digital services of each respondents, we conducted the questionnaire survey for 343 samples. Findings of our research hold that the group who showed higher level of convergence tends to use the socialized digital services more. Convergence generation were heavy users in appstore on smart-phone and wireless game and more participating. In digital service area, facebook/cyworld, twitter, UCC, portal, internet community in digital service. Convergence generation are global network communication, buying decision making activity, actively opinion expression, prosumer attitude, dependency on digital device, experience based purchase behavior, enthusiastic information sharing.

Fingerprint verification is being adopted widely to provide positive identification with a high degree of confidence in all practical areas. This popular usage requires reliable methods for matching of these patterns. To meet the latest expectations, the paper presents a pair wise distance histogram method for fingerprint matching. Here, we introduced a randomized algorithm which exploits pair wise distances between the pairs of minutiae, as a basic feature for match. The method undergoes two steps for completion i.e. first it performs the matching locally then global matching parameters are calculated in second step. The proposed method is robust to common problems that fingerprint matching faces, such as scaling, rotation, translational changes and missing points etc. The paper includes the test of algorithm on various randomly generated minutiae and real fingerprints as well. The results of the tests resemble qualities and utility of method in related field.

The reciprocal relationship between the interpersonal tie and the internet dependency is focused in the study. Mainly, chi-squire test and ANOVA are used in testing the hypothesized relationship of the internet dependency with the interpersonal tie before and after using internet. The strong relationship with the internet dependency is found in internet's both-directional communicating function such as chatting, game, gambling, etc. The level of internet dependency is high when individual's tie with friends, colleagues, or neighbors is strong; but it is lower when individual's emotional tie with family members is stronger. It is confirmed that excessive usage of internet damages family relationship. Conversely, it is also clear that the emotional support from family members is essential for preventing or enhancing internet dependency. This implies that internet dependency is not an individual problem, but that it should be treated under the consideration of his/her family system.

본 연구는 모바일 게임의 이용의도에 관한 연구로서 기존연구들을 바탕으로 한국과 중국 양국간의 차이를 비교하고자 한다. 기존의 연구에서 제시한 게임의 이용의도인 탈출, 사회적 상호작용, 경쟁/도전감, 환상감, 시간 보내기에 모바일기기의 이용의도인 정황성, 과시욕을 추가하여, 중국의 모바일 게임 이용자들의 이용의도를 조사하고 한국의 모바일 게임 이용의도와 비교하고자 한다. 본 연구를 통해서 중국과 한국 게이머의 이용의도에 있어서 공통점과 차이점이 무엇인지를 파악하고, 양국의 사회문화적 특성이 이용의도의 차이에 미치는 영향에 대해 설명하고자 한다. 현재 소수의 한국 게임기업들이 중국에 진출하고 있고 중국의 문화와 시장을 충분히 파악하지 못하고 있는 실정이다. 본 연구의 결과는 향후 한국기업이 중국 모바일 게임 시장에 진출하는데 도움이 되는 시사점을 제시할 수 있을 것으로 여겨진다.

This paper measures and compares the traffic of a series of Massively Multiplayer On-line Role Playing Games(MMORPG). The target games are 'Lineage' and 'Lineage II' developed by NCsoft, which are ones of the world's largest MMORPGs in terms of the number of concurrent users. We collected about 1 tera bytes of packets of 'Lineage II' for four days including a weekend. These packets are analyzed and compared with those of 'Lineage.' Packet size, packet inter-arrival time, and bandwidth usage are compared. The traffic of the two games shows much difference because original 'Lineage' is a kind of 2-D based MMORPG, while 'Lineage II' is 3-D based. By comparing the characteristics of the traffic of these games, we can anticipate future needs of network and game structure.

Unlike using smart-phone for music, game, information searching, shopping, using smart-phone for tasks may be forced in the task environment. Therefore, attitude, usefulness, and easy of use of technology on information technology adoption mode can not fully explain using smart phone for tasks. To explain using smart phone for tasks, this paper is based on the theory of task and technology fit(TTF) that TTF influences the usage performance of technology.
