지난 50여년간 사용해 왔던 아날로그TV가 디지털로 전환되면서, HDTV급 고화질과 CD급고음질의 TV 서비스를 안방에서 즐길 수 있게 되었다. 그러나, 사회가 매우 다양화됨에 따라 시청자의 활동성 및 생활 패턴도 과거와는 매우 달라졌으며, 휴대폰, PDA, 노트북 컴퓨터 등 휴대용 기기가 일반화됨에 따라 이동 중에도 선명한 화질의 TV를 즐기고자 하는 요구가 급속히 증대되고 있다.(중략)

현재, 인터넷이 정보화 사회의 핵심 인프라로 자리를 매김에 따라 사용자가 폭발적으로 증가하게 되었고, 이로 인한 주소 부족 현상이 심화되고 있다. 한편, 국방정보통신망에서도 통신대상의 증가 및 서비스 품질보장, 전술통신체계의 이동성 및 생존성 보장을 요구하고 있다. 이러한 변화는 주소부족 문제 해결, 이동성, 보안성, QoS 보장 서비스 등 다양한 기능 지원이 가능한 IPv6의 도입이 요구된다. 이에 따라 국방정보통신망에서의 IPv6 도입 전략에 대한 연구가 진행되었다. 이미 시작된 IPv6 도입 전략과 연계하여 본 논문에서는 우리 군에 IPv6로의 전이를 효과적으로 지원하기 위해 웹 기반 IPv6 전이 지원 시스템을 설계하고자 한다. 그리고 설계된 체계를 활용하여 국방정보통신망 시스템 자원을 기반으로 IPv6 전이 지원 절차에 따라 점검 자원 DB를 구축한다. 웹 상에서 IPv6로의 전이 요청 부대 실무자가 전산자원에 대한 전이절차 정보 및 예산산출 정보를 지원 받음으로써 IPv6로의 전이를 체계적이고 신속하게 지원하게 된다.

고도의 정보화 사회로의 움직임이 더욱 가속화됨에 따라 이동성이 용이한 정보표시장치의 필요성이 급격히 증대되고 있으며, 이에 따라 평판 디스플레이의 비중이 커지고 있다. 특히 소형 평판 디스플레이의 경우 OLED를 이용한 디스플레이는 TFT-LCD, PDP, FED 등 다른 디스플레이 보다 낮은 구동 전압으로 구동할 수 있고, 자체 발광하기 때문에 인식성이 뛰어나며, 얇고 가벼우며 응답속도가 빠르고 넓은 시야각을 가져 차세대 평판 디스플레이 중의 하나로 차츰 그 응용범위가 넓어지고 있다. (중략)

This study aims to provide important data for community-centered rehabilitation by examining factors influencing community participation after the onset of stroke. The study subjects were 100 patients with a stroke for more than six months. Korean Craig Handicap Assessment and Reporting Technique (K-CHART) was conducted to determine the level of participation of subjects, and Korean-Modified Barthel Index (K-MBI) was conducted to examine the factors influencing the community participation of the subjects to determine the level of independence of activities of daily living. As a result, the relevant factors of community participation in stroke patients were as follows. Physical independence, cognitive independence, mobility, work, and social integration of stroke patients showed higher explanatory power than engagement in activities of daily living, age, and employment. Also, physical independence, cognitive independence, mobility, work, and social integration were factors that affected participation. All items were statistically significant (p <.01). It is considered that this study will contribute to providing information for focusing on occupational therapy for increasing the social participation of stroke patients, and proper evaluation and intervention will work as essential rehabilitation factors for improving participation with respect to the influential factors of participation.

This study investigated the differential effects of subjective evaluation for attention and situation adaptability, and motivation on driving mobility as a function of driver's age. The results can be summarized as followings. First, subjective capability evaluation tended to decrease as the drivers' age increased, and lower evaluation for situation adaptability seemed to be recognized earlier than attentional ability in middle-aged drivers. Second, although subjective evaluation for attentional ability predicted positively driving mobility of all age groups, but only subjective evaluation for situation adaptability predicted positively driving mobility of older drivers. Third, among motivational elements, BAS predicted positively driving mobility of young and middle-aged driviers, whereas BIS predicted positively driving mobility of older drivers. Finally, middle-aged drivers tended show increased driving mobility when their attentional ability score and BAS were high, whereas older drivers showed lowest level of driving mobility when their situation adaptability score and BIS were low. These results suggest importance of integrated consideration for drivers' subjective evaluation for attention and situation adaptability, and motivation to understand characteristics of driving mobility in different age groups.

This study examined the relationship among children's theory of mind, social skills, and emotional intelligence. A total of 76 five-year old children in the Seoul area participated in this study. Children were tested on three different type of theory of mind tasks and teachers rated their children's emotional intelligence and social competency. SPSS 18, t-test, correlation analysis, and step-wise of multilateral regression were performed for data collection. The results were as follows: First, 40.8% of participants passed the task of theory of mind. There were significant differences in total score of theory of mind, social competence skills, and emotional intelligence between successors and failures. Second, by gender, there were significant differences in total score of theory of mind, social competence skills, and emotional intelligence. Third, there was a relationship between theory of mind and social competence skills, social competence skills and emotional intelligence, and theory of mind and emotional intelligence.

To analyze mobility patterns, this study used three Constraint (Capability Constraint, Coupling Constraint, Authority Constraint) models which were proposed in Dr. Hagerstrand's Time-space theory. This paper shows that three constraint models have some effects upon mobility by age. In this study, Capability Constraint means a certain special constraint that is what we can't do during proceeding basic natural urges like sleep, fare, etc. Coupling constraint is a physical one. Each person limits the action range for staying on a special place in special time. For instance, students have to stay in school so that they have mobility constraints. Authority Constraint is a social one. When we use urban facilities or traffic, we may be controlled by mobility sphere by an agreement or a social position. It is social agreement that the opening hour of a store, the time table of mass-transportation and a social positional control that the personal income, the standard of education. In this study it has been in a process of determination of the cluster number that degree of influences a social constraint to mobility. Considering the mobility constraint of characteristics of space divides urban and rural, people in urban area have higher mobility rate than in rural area. Resuets of determination of the cluster, show similar mobility pattern. People in urban area are connected verity of mobility which related to urban space structures with determination of cluste-number. That is to say, mobility patterns can be changed by space charactcristics. Constraints by sex and age are also social constraints and they are influenced by mobility patterns. For instance, females at the age of twenties have similar mobility pattern to the same age male but they have sudden changes after thirty's age. Male entertains a similar pattern without restriction of age. That is to say, management by sex as a social constraint affects mobility. To establish more realistic traffie policy, mobility formation should be reflected to the space in a view of social-behavioral science. To embody this, some problems should be investigated as follows. 1. As a problem of methodology, if sufficient samples ensured, we could subdivide clusters and could open up a new method of analyzing the mobility clusters by using the neuro-network. 2. Extracting actions connected with mobility and finding life cycle which is classified by daily cluste-characteristics, suitable counterproposal could be presented to the traific policy.

Rapid development of information and communication technologies leads firms to take 'smart work' into serious consideration as a new way of working in coming knowledge and information society. However, some jobs may be fit for smart work while some may be not. A $2{\times}2$ framework for smart work readiness assessment is developed in this study through the review of extant literature and a series of focus group activities. Two critical dimensions of smart work are derived and presented as a result: smartness (knowledge versus data) and mobility (mobile versus static). Knowledge intensive jobs with possible mobility seem to be the target group that can be easily converted to smart work while mobile workers with interactive data processing devices seem to be already doing smart work. As mobility is a critical presumption for work to be flexible in terms of time and place, jobs with no mobility are assessed here as not ready for smart work at least at present. This framework is experimentally applied against the published job statistics 2011 in Korea, and used to estimate the number of workers ready for smart work. As a conclusion, discussions on policy implications and further research issues are made at the end.

유비쿼터스 사회에는 도서관, 커피숍과 같은 공공장소와 자동차, 전철, 비행기등과 같은 대중교통에도 인터넷에 접근할 수 있게 될 것이다. 또한 모든 통신은 끊임없는 인터넷이 지원되어야 하고, 세션이 유지되어야 하며, 이동 중에 통신이 끊어지지 않고, 라우팅이 효율적으로 이루어져야 한다. 이러한 요구를 반영할 수 있는 네트워크 이동성 기술은 이동 IPv6이 가지고 있는 근본적이고, 비효율적인 삼각 라우팅 문제와 중첩된 환경에서 삼각라우팅 문제가 반복되는 핀볼 라우팅 문제를 가지고 있다. 본 논문은 중첩환경의 라우팅 문제를 조사하고, 해결하기 위해 이미 제안된 내용들을 분석하고, 효율성과 안전성을 만족할 수 있는 프로토콜을 제안한다.
