We proposed a fast detection of copy-move image forgery using four step search algorithm in the spatial domain. In the four-step search algorithm, the search area is 21 (-10 ~ +10), and the number of pixels to be scanned is 33. Our algorithm reduced computational complexity more than conventional copy move image forgery methods. The proposed method reduced 92.34 % of computational complexity compare to exhaustive search algorithm.

EO TGP(Electro-Optical Targeting Pod) is an optical tracking system which has various functions such as target tracking and image stabilization and LOS(Line of Sight) change. Especially, it is very important to move the LOS into a interest point for joystick command. When pilot move joystick in order to observe different scene, EO TGP gimbals should be operated properly. Generally, most EOTS just operate corresponding gimbal for joystick command. For example, if pilot input horizontal command in order to observe right hand screen, it just drive azimuth gimbal at any position. But in the screen, the image dosen't move in a horizontal direction because gimbal structure is Euler angle. And image rotation is occurred by elevation gimbal angle. So we need to move Pitch gimbal. So in the paper, we designed LOS moving algorithm which convert LOS command to gimbal velocity command to move LOS properly. We modeled a differential kinematic equation and then change the joystick command into velocity command of gimbals. This algorithm generate velocity command of each gimbal for same horizontal direction command. Finally, we verified performance through MATLAB/Simulink.

This study aims at reviewing satisfaction on facility modernization project of traditional market by case study on integration & move method of 2 markets (Seongbuk 5 day market & Geumgye daily market). Following this study, it asked 182 merchants & customers at Naju Moksagoeul Market about satisfaction and performance on integration & move and the facility modernization project of traditional markets. According to results of the survey, not only merchants but also customers are satisfied with the modernization project. But in detail, valuations between 5 days market and daily market, and between merchants and customers are different. For example, merchants regard as negative, but customers as positive about move of the markets from city to outside. About half of respondents answer that number of market visits and sales volume after move of the markets are higher than before. More than 80% of respondents answer that culture & tourism market programs are helpful to the market revitalization.

Objective: This study presents an observation and analysis on behavioral characteristics of old users in comparison to young users in the use of control on display interface. Background: Touch interface which allows users to control directly on display, is conceived as delight and easy way of human-computer interaction. Due to the advantage in stimulus-response ensemble, the old users, who typically experiencing difficulties in interacting with computer, would expected to have better experience in using computing machines. Method: Twenty nine participants who are over 50 years old and 14 participants who are in 20s years old were participated in this study. Three primary tasks in touch interface, which are tap, move, and flick, were delivered by the users. For the tap task, response time and point of touch response were collected and the response bias was calculated for each trial. For the move task, delivery time and the distance of finger movements were recorded for each trial. For the flick task, task completion time and flicking distance were recorded. Results: From the collected behavioral data, temporal and spatial differences between young and old users behavior were analyzed. The older users showed difficulty in completing move task requiring eye-hand coordination.

The purpose of this study was to examine predictors of move intention to silver town in Jeju Island. Participants were 449 middle age and elderly who live in Seoul, Gyungido, Inchun Metropolitan and Jeju island. Participants were completed a questionnaire and/or structured interview that included measures of socioeconomic variables, motivation to move, determinants of move selection, conditions of location, and preparation for old age. Results of descriptive analysis revealed that cognition level of sliver industry and silver town was relatively high and medical service was the best necessary field, followed by field of leisure activity, house, life and finance. Logistic regression analyses on the effects of socioeconomic variables on move intention indicated that region, occupation and house ownership had significant effects on move intention to silver town. Result of motivational effect on move intention revealed that solution of offspring's burden was the most important factor, followed by convenient life of the aged, enjoyment of freedom for the elderly life. Result on the influence of determinants of move selection indicated that medical service facilities, resort facilities and leisure, cultural service facilities had significant effect on move intention. Among conditions of location for Jeju island, mild climate, comfort environment and low-price were significant predictors on move intention. Overall, result on relative influence of individual factors indicated that low price factor was the most important predictor, followed by resort facilities, cognition on necessity of silver town, enjoyment of freedom for the elderly life, leisure cultural service facilities, and medical service facilities.

Suppose that G is a group of permutations of a set ${\Omega}$. For a finite subset ${\gamma}$of${\Omega}$, the movement of ${\gamma}$ under the action of G is defined as move(${\gamma}$):=$max\limits_{g{\epsilon}G}|{\Gamma}^{g}{\backslash}{\Gamma}|$, and ${\gamma}$ will be said to have restricted movement if move(${\gamma}$)<|${\gamma}$|. Moreover if, for an infinite subset ${\gamma}$of${\Omega}$, the sets|{\Gamma}^{g}{\backslash}{\Gamma}| are finite and bounded as g runs over all elements of G, then we may define move(${\gamma}$)in the same way as for finite subsets. If move(${\gamma}$)${\leq}$m for all ${\gamma}$${\subseteq}$${\Omega}$, then G is said to have bounded movement and the movement of G move(G) is defined as the maximum of move(${\gamma}$) over all subsets ${\gamma}$ of ${\Omega}$. Having bounded movement is a very strong restriction on a group, but it is natural to ask just which permutation groups have bounded movement m. If move(G)=m then clearly we may assume that G has no fixed points is${\Omega}$, and with this assumption it was shown in [4, Theorem 1]that the number t of G=orbits is at most 2m-1, each G-orbit has length at most 3m, and moreover|${\Omega}$|${\leq}$3m+t-1${\leq}$5m-2. Moreover it has recently been shown by P. S. Kim, J. R. Cho and C. E. Praeger in [1] that essentially the only examples with as many as 2m-1 orbits are elementary abelian 2-groups, and by A. Gardiner, A. Mann and C. E. Praeger in [2,3]that essentially the only transitive examples in a set of maximal size, namely 3m, are groups of exponent 3. (The only exceptions to these general statements occur for small values of m and are known explicitly.) Motivated by these results, we would decide what role if any is played by primes other that 2 and 3 for describing the structure of groups of bounded movement.

The purpose of this study was 1) to analyze the attitudes of people in their 50s about housing problems, and, 2) to study their intention to move into senior congregate housing. The survey was conducted from October to November, 2003 in the Seoul Metropolitan area.'rho data L4·Pre collected from m people using a questionnaire. The results were as follows: First, respondents listed 'friends' as the most important element of their later life. Next, in general, they preferred to live in mainstream family housing. Respondents thought 'family and government' had a responsibility to solve senior citizens 'housing problem. Second, a majority of the participants showed an intention to eventually move into a senior congregate housing. However, the group who did not Intend to live in senior congregate housing had a higher income and greater property assets. The appropriate time for the move to senior congregate housing was keyed to a desire to avoid loneliness. On the other hand, a high degree of satisfaction with current housing was the primary reason given for not wanting to move to senior congregate housing. In conclusion, senior congregate housing should be developed as a model for the middle class and might be successful when combined with a high quality social and health program.

The clinical diagnosis of ankylosis can be made only when the affected tooth gives positive evidence of an inability to move. The inability to move is demonstrated either as a failure of the tooth to move with normal vertical dental alveolar growth or a failure of the tooth to move when the tooth is subjected to an orthodontic force system. This case report describes the autotransplantation of an ankylosed maxillary canine.

This study identifies intention to move, reasons for moving and housing preferences of US residents 55 and older living in non-subsidized and market-rate multifamily housing in the United States. Data were collected using an on-line survey; mixed methods were used for data analysis (N=431). Results show that more than half of the respondents intend to move. Senior residents who were younger than average age of the respondents, not married, renters, had no elevator, and reported lower residential satisfaction with their housing unit, multifamily housing community and local area were more likely to intend to move. Seven reasons for considering moving were found: finance, health, lifecycle stage, housing unit, multifamily housing community, other. When asked about their future housing, more than 80% desired independent living rather than assisted living facilities or nursing homes, 40% wanted to live in multifamily housing, and 51% hoped to own their housing rather than renting. The findings offer meaningful information to the multifamily housing industry in the United States and in countries where the population is aging and where multifamily housing is the predominant housing type.

As the society progresses to a knowledge economy, global demand is rapidly increasing in many fields of society. In line with this, interest in globalization is also increasing in universities. Accordingly, students who have graduated from universities are making efforts to find employment in Korea, but the barriers to entry for employment are high due to the high specifications and qualifications of domestic companies, so the government, local governments, and universities are putting a lot of effort into global overseas employment. This study is a training course design for the K-MOVE project aimed at employment in Japanese IT companies. To design this curriculum, we conduct a demand survey of recruiting companies and students, and draw a curriculum based on the results. Then, the effective link between regular subjects and K-MOVE education will be described. This study can be a useful resource for education experts planning overseas employment in the Japanese IT field.
