  • In order to prevent tampering and reverse engineering of executive code, this paper propose a new tamper resistant software mechanism. This paper presents a cryptographic MAC function and a relationship which has its security level derived by the importance of code block instead of by merely getting the encryption and decryption key from the previous block. In this paper, we propose a cryptographic MAC function which generates a dynamic MAC function key instead of the hash function as written in many other papers. In addition, we also propose a relationships having high, medium and low security levels. If any block is determined to have a high security level then that block will be encrypted by the key generated by the related medium security level block. The low security block will be untouched due to efficiency considerations. The MAC function having this dynamic key and block relationship will make analyzing executive code more difficult.

  • Robot design serves as the crucial link between a human and a robot, the cutting edge technology. The importance of the robot design certainly will be more emphasized when the consumer robot market matures. For coexistence of a human and a robot, human friendly interface design and robot design with consideration of human interaction need to be developed. This research extracts series of functions in need which are consisted of series of case studies for planning and designing of 'A Shopping Support Robot'. The plan for the robot is carried out according to HRI aspects of Design and the designing process fellows. Definite results are derived by the application of series of HRI aspects such as gestures, expressions and sound. In order to verify the effectiveness of application of HRI aspects, this research suggests unified interaction that is consisted of motion-capture, animation, brain waves and sound between a human and a robot.

  • Pedestrians and vehicle users should be treated with equal importance in urban street design. However, current street design suggests that the design criteria for sidewalks is based on the functional hierarchy of the vehicles, therefore it is necessary to develop sidewalk design standards that give more weight to pedestrians rather than vehicles. For this, this study suggests that the level of service of pedestrians should be considered in the process of designing sidewalks. Currently, level of service (LOS) criteria for pedestrians in the Korean Highway Capacity Manual are based on pedestrian volume, but the volume of pedestrians is seldomly estimated in practice. So, the current LOS criteria has limitations in terms of practical use. Also, the study assumes that the pedestrian flow rate is hardly the dominant factor that could affect the LOS of pedestrians at most urban sidewalks. In this context, the study considers a new LOS for sidewalk design based on the comfort of pedestrians while passing pedestrians coming from the opposite direction. Then the study attempts to link the new LOS criteria to the land use patterns using data of pedestrian traffic characteristics acquired from the field. In addition to this, the scope in which the suggested criteria can be applied is suggested.

  • The role of information in knowledge society has changed. Library refers to information centre, which is actively involved information collection and promoting use of for the development of individual and society. Modern libraries are the centres of interaction for all interested in accessing information and in participating in the marathon of the present competitive age. Information and a conducive environment of its free flow is a vital tool in all forms of human endeavour. It is the link pin of national development. For a nation to develop it needs to have and provide relevant, updated and adequate information on food security, health, democracy, population, education, family planning, youth empowerment, gender quality, environment etc. The information intermediaries are the persons to modulate these complexities and find match between the information sources and users needs to satisfaction of Ranganathan's law: Books are for use; Every reader his/her book; Every book its reader; Save the time of the reader; Library is a growing organism. The relative importance of these norms in modern context has been evident from experience, study, observations, discussions, etc., and only by scientists and technologists, but also by managers, planners, and policy makers. They recognize the usefulness of information in the performance of their needs information needs. Libraries are therefore proper management, provision and dissemination of such information. It is clearly visible in the contemporary context, that the libraries in the knowledge society are much more than the book depositories This article looks at the theory/practice divide in library and information science and particularly Ranganathan's contributions, basic statements remain as valid in substance if not in expression as -to-day as when they were promulgated, concisely representing the ideal service and organizational philosophy of libraries today.

  • We spend about one-third of our life sleeping. Although the influence of sleep on various cognitive and affective functioning is recognized, relatively less is known about its consequences on interpersonal relationships. The present study examines whether sleep contributes to adolescent's peer intimacy; specifically, given the role of sleep in memory consolidation, it was assumed that a good sleep will enhance social relationships by positively refurbishing memories of social episodes. As predicted, young teenagers' sleep quality predicted increased peer intimacy, partly through the positive memory of social events, in a sample of middle school (Study 1) as well as high school participants (Study 2). To investigate the causal link, in Study 2, memory recollections were repeatedly measured for a week. Sleep quality during the week predicted how social, but not non-social episodes were positively remembered. The function and importance of sleep quality are discussed in the context of interpersonal relationships.

  • Ousters have become a key focus of interest and analysis over the last decade or so, informed by the work of the Harvard business economist Michael Porter. Recent research, however, suggests that the classic Porterian conception of clusters needs to be rethought. In particular, the idea that clusters are geogaphically bounded and integrated units whose primary link to the outside world is through the export of goods and services to global markets is highly Questionable, if not untenable. Relational approaches to clusters and regional development stress the importance of the wider networks and 'pipelines' through which knowledge is exchanged with key partners and collaborators located outside of the particular cluster in question. Rather than the main external links being those between leading firms and global markets, firms may engage in a range of global relations with collaborators and suppliers. This paper address the challenge of rethinking clusters in the light of the recent emphasis on global networks md connections, drawing on experience from m old industrial region in Western Europe Scotland. In assessing cluster experiences and initiatives in Scotland, I examine the development of the oil and gas and electronics clusters. In conclusion, I suggest that cluster initiatives me only likely to generate lasting benefits for the region in question if there is significant local ownership md control of key industries and clusters.

  • On the border between the Geography subject and the Science subject, much of the content area is found to be interrelated or shared in common due to the characteristics of each subject. This possibly causes a problem of which of the two subjects should treat these overlapping areas with more responsibility and importance, and, as a result, might cause teachers to neglect the areas and result in insufficient treatment of the areas on both sides. In other words, these overlapping area can be overlooked on both subjects. On the other hand, as the science subject treats these areas more deeply and widely in both quantity and quality, the geography subject might lose its original content area to the science subject and accordingly lose its characteristics as an independent subject. To conclude, the following suggestions must be taken into consideration when we develop and organize the environment-related unit in the geography subject. First, the various real cases damaged by pollution, the efforts and steps to avoid being polluted, the inquiry questions and activities to set up the value of the environment conservation, and sufficient assistant materials such as maps, graphs, photos, illustrations, statistics, which will help to realize the environment problem more directly and clearly, must be presented in the textbooks. Second, as the environment education is not just teaching the environmental pollution, the content should be composed for the students to realize the value of the environment and to change their awareness and attitude toward the environment. Third, the environment education cannot be restricted to a certain subject, or it needs to be approached in multi-subject areas. To exercise a effective environment education while we maintain the unique characteristics of the geography subject, a way to link the environment and the region, which is one of the main concepts of geography, should be developed. Finally, textbooks are indispensible materials to teaching-learning, but for more effective teaching the teachers of geography should try to recompose and reorganize the content and to develop newer and more effective teaching material-aids.

  • Diverse disciplines such as information science, computer science, cognitive science, and industrial design, are activity engaged in the website evaluation research efforts. Information scientists emphasize the importance of user-centered and user-friendly website design, which is also easy to use, This idea is based on the understanding that the users and the designers are different set of people. In addition, information scientists consider the practice of maximally incorporating user inputs during the website design to be very important guideline. However, this study is based on a newly emerging population of website users who are also designers. 218 study participants evaluated the websites that they designed in comparison to the websites designed by others. According to the survey data analysis, the study participants considered the content delivery, design simplicity, design consistency, and link access of the websites to be equally important from both users' and designers' perspectives. However, the content organization, rich content, and screen composition were underestimated from the designers' point of view whereas these factors were considered to be important from users' point of view.
