Recently in the field of information design use of multimedia Including animation has been rapidly increased. And its application is expanding in the field of design nevertheless relevant research in this field is scant. In particular research on which characteristics contribute to improvement for effect of information communication is negligible. Until now designers' interest was mainly focused on visual perfection of screen such as diversity and originality. Actually the aspect of recognition of design was mostly overlooked. But considering ultimate purpose of Information design is accurate communication of information thus there should be more endeavor for research on man's visual recognitive faculty and memory in order to Improve power of communication of information for the purpose of reducing confusion of user before its originality and diversity. For this reason this author in this treatise attempted to examine possible impact of multimedia in information design on recognition of user and communication based on theory of effectiveness of media and also attempted to identify how maximize its effect under different circumstances. Theories on effectiveness of media can be summed up as that well- advanced information of multimedia should be analysed from diverse standpoints on relevancy to tasks and recognitive relevancy rather than its simplification from the standpoint of richness of media. For optimal interface design unnecessary recognitive load should be eliminated and information should be structured by laking maximum advantage of working memory of limited quantity. Also there will be need for selection of proper media and suggestion of expressive method to enable building accurate and successful mental image. In this treatise this author attempted to contribute to designer's decision making in future through examining theories on effectiveness of media in connection with the question of which information technology should be used in order to heighten effect of information communication appropriate to information design.

This study explored the role and characteristics of music that contributed to experiences of catharsis in music. An empirical phenomenological study was conducted to explore catharsis with 12 adults. Phenomenological reduction, change of attitude, literature interpretation, and hermeneutic circle were used for data collection and analysis. As a result, three categories, five themes, and 11 sub-themes were identified. The first category, here and now in music consisted of two themes: aesthetic experiences and expansion of musical novelty. The second category, inner connection through music consisted of one theme, re-experience of internal emotions. The third category, immersion and engagement in music consisted of two themes: ventilating or deepening of emotions and internal dynamics. Based on these results, the cathartic characteristics of music are discussed. First, the aesthetics and novelty of music kept participants fully stay in music. Second, music induced a re-experiencing of emotions by triggering memories or stimulating unresolved emotions. Third, the elements of music promoted emotional ventilation, deepening, and internal dynamics. This study is meaningful because it qualitatively examined the roles and characteristics of music that contribute to cathartic experience in the general adult population.

This study started from recognizing the need to study place identity from the perspective of residents experiencing the place in daily life. The subject area of the study, Shin-Cheorwon, Galmal-eup, Cheorwon-gun, Gangwon-do area, had a low population until the division of Korea in 1945. Since then, the residents have created the milieu under Shin-Cheorwon's regional historic and cultural context. Thus, the study on this area can show the formation of the interrelationship of the region and residents. The purpose of this study is to understand the meaning and identity of the everyday places of Shin-Cheorwon. Photovoice was chosen as the method for successful Participatory Research; Participant's active intervention stage, 'Documentation (4th step)', Narration (5th step), researcher's analysis stage 'Ideation (6th step)' were specifically used. As a result, the following characteristic of the places chosen by participants could be found: the meaning and relationship with the residents, similarities, and differences in people shown based on their age, length of residence, etc. Through this, participants recollected the past places, found the meaning of the place of the present, and deduced the placeness that Shin-Cheorwon should have in the future. The study identified the place identity that holds the perspective of the residents in their daily life and provides implications on the follow-up studies of place identity. In addition, it is expected that it will apply to urban planning and spatial design in further studies of how residents perceive the space formed by urban development using photovoice methodology.

Recently, as the personal computers are supplied rapidly, they formed the nucleus of the computer system. But, because of the easiness that anyone uses them to go near easily, it is the fact that the security of personal computer is weakness. So, in the paper, 1 propose the technical method that minimizes the loss and leakage of important data. This paper implemented a crypto system for security of data file on personal computer and assistance storage medium. The way of encryption/decryption is applied by complexity method which mixed Diffie-Hellman key exchange protocol, a typical RC4(Rivest Cipher version 4) algorithm of stream cipher and a typical MD5(Message Digest version 5) of Hash Function. For valuation implemented crypto system, three criteria is presented, which are crypto complexity, processing time and pattern matching. And according to analysis the three criteria the crypto system is verified the security, efficiency and usefulness. The crypto system is programmed with Visual C++ language of Microsoft. And so, as this is software system, we shall have a technical security system at a minimum cost for all personal computer.

This paper proposes a multi-level thresholding method for image segmentation using fuzzy clustering algorithm in transition region. Most of threshold-based image segmentation methods determine thresholds based on the histogram distribution of a given image. Therefore, the methods have difficulty in determining thresholds for real-image, which has a complex and undistinguished distribution, and demand much computational time and memory size. To solve these problems, we determine thresholds for real-image using fuzzy clustering algorithm after extracting transition region consisting of essential and important components in image. Transition region is extracted based on Inか entropy, which is robust to noise and is well-known as a tool that describes image information. And fuzzy clustering algorithm can determine optimal thresholds for real-image and be easily extended to multi-level thresholding. The experimental results demonstrate the effectiveness of the proposed method for performance.

In , music becomes a passage of spaces in dreams and at the same time causes a problem of temporality between spaces with different time speeds. This paper aims to examine the temporality of the music through Bergson's concept of time. The music used in the film, 《Non, je ne regrette rien》, is divided into the original version, the slowed-down version, and the rearranged version with the slowed-down, and this study visually confirmed the characteristics and similarities through practical analysis. From the perspective of Bergson's perception and memory diagram, non-diegetic music of the actual(the rearranged version) in which diegetic music of the virtual(the slowed-down version) inherent, plays the role of film music and music signal simultaneously. Also, the original version and the slowed-down version are the relationship of durational identity with qualitative changes. We looked at the position in the inverted cone diagram and applied their relationship to the diagram. It is a great achievement of this study that we explored the temporality of music in the multi-layered structure of , based on Bergson's philosophy of coexisting with the present and the past.

Enforcing additional authentication to password-based authentication, in addition to attempting to increase the security of the password itself, helps to improve the security of the password authentication scheme. For a well-known problem of using strong passwords that differ from site to site, we propose a scheme for password generation and management with an inherent supplementary authentication. Like the so-called password manager, the scheme retrieves and presents a strong site-specific password whenever requested without requiring the user to remember multiple passwords. Unlike the existing methods, however, the scheme permits the password retrieval process to proceed only through the authenticated user's ownership verified smartphone. Hence, even for sites not enforcing or supporting two-factor authentication, the logon process can benefit from the scheme's assurance of enhanced security with its two-factor equivalent authentication. The scheme can also prevent an attacker from impersonating a user or stealing secrets even when the stored information of the server for password retrieval service or the user's smartphone is leaked.

Being engaged in the musical tasks needs cognitive skills to perceive musical sound, organize them into meaningful unit, store them in the memory and retrieve them when needed. These skills are also required for academic tasks indicating that there is positive correlation between skills for musical and academic tasks. Based on these findings, the study purported to examine whether the developed sessions can enhance cognitive skills which is composed of auditory information skills, which is composed of perceiving sounds, organizing them into groups based on the existing information or organization pattern, and short-term memory skills. Eighteen elementary students in 4, 5, and 6th grades have participated in the study. The study has administered Music Cognitive Skills Test(MCST) before and after implementing music therapy sessions. The MCST consisted of five parts, first one measuring the rhythm imitating skills, second, measuring the melodic imitation skills, third, measuring discriminative skills in identifying higher pitch, fourth, measuring discriminative skills in identifying identical chords, and lastly, measuring the tone retention skills. The results indicated that there was statistical difference between the pre and post test in rhythm and melody imitation skills. Because reproduction of perceived rhythm patterns requires memory skills, imitating patterns are considered cognitive skills. Also melody is defined adding spatial dimension to the rhythm which is temporal concept. Being able to understand melodic pattern and to reproduce the pattern also requires cognitive skills. The subjects have shown significant improvement in these two areas. In other areas, there were definite increase of scores, however, no significant differences. The study also explores interpretation of these results and also observed consistencies among the participants in completing the musical tasks.

Animal models can provide a useful tool for the study of some aspects of psychiatric disorders and their treatment. The four criteria for the evaluation of animal models of psychiatric disorders are as following : 1) similarity of inducing conditions 2) similarity of behavioral state 3) common underlying neurobiological mechanisms 4) reversal by clinically effective treatment techniques. Several animal models have been proposed for schizophrenia : phenylethylamine model, L-dopa model, hallucinogen model, cocaine model, amphetamine model, phencyclidine model, noradrenergic reward system lesion model, reticular stimulation model, social isolation model, conditioned avoidance reaction, catalepsy test, paw test, self-stimulation paradigms, latent inhibition paradigms, blocking paradigms, prepulse inhibition of the startle reflex, rodent interaction, social behavior in monkeys, hippocampal damage, high ambient pressure, and models using selective breeding. Among them, animals with bilateral lesion of the hippocampus may provide an adequate animal model for several symptoms of schizophrenia, and ketamine model can reproduce negative symptoms and cognitive deficits as well as positive symptoms of schizophrenia. In conclusion, no model of schizophrenia is entirely representative of the disease, and findings gleaned from model systems must be cautiously interpreted. Furthermore, the process of developing and validating animal models must work in concert with the process to identify reliable measures of human phenomenology.

Multiculturalism may be deeply connected with the diversities of cultures and enlightenment discussed in the context that we live together with the specification of cultures derived from any spatial conditions overtly and covertly. People live on their own customs compatible with their space and the time, and they make their boundaries of races, nations, and national memories. In such a way each of them treats each other exclusively and is inclined not to recognize being of the others. Also people are apt to recognize the others unessentially and overlook the others's value and way of life. As a result they might destroy the foundation of symbiotic livings conditions on their own. On the other hand they pretend to search for the cultural diversities of the others and include them under their own universalities, resulting in conflicts. Hence it is required that we should make an efforts to prepare the fields for living together through getting over the problem of the recognition of matters and affairs before us. From the above-told critical mind this thesis seeks the multicultural relativities and more arrives at the relationalities discussed by East-Asiatic philosophers of Chuang Tzu and Ch'oe Han-gi. Especially by gazing at the idea of the interconnectedness which means activities, changeabilities and mobilities, appeared on the idea of Ch'oe Han-Gi's revolving transformation, it is stressed that the communications of the local with each other in the various aspects of, e.g. materials, regions and cultures should be achieved.
