According to Mead's (1934) symbolic interaction theory, social roles are learned through interaction and experiences in everyday life. Over time, these rules of behavior become internalized and serve to structure one's actions accordingly. Ultimately, these rules provide us with a powerful means of controlling our actions, and in time, they define our identity. Transforming the socialization process is one's conscious interpretation of stimuli through the use of symbols. Furthermore, society's perceptual processes can be shaped by the symbols we learn. The meaning of symbols can be learned from a variety of social influences, one of which may be mediated messages and advertising. This paper attempts to establish a link between media exposure and one's perception of social reality regarding character judgments made of unknown others based on the target's product or brand usage. Using magazine advertisements for fictitious products, the experiment herein seeks to establish two fundamental goals: 1) to determine if perceptions can be manipulated via association with companion symbolic elements: and 2) to detect whether television exposure is a moderating factor. Respondents were asked their perceptions of both product quality and of product users.

세선화 알고리즘은 문자인식, 도형 및 도면 인식 등에 매우 중요하게 사용되고 있다. 세선화 알고리즘은 여러 가지 방법으로 제안되어 왔다. 본 논문에서는 이전에 제안된 세선화 알고리즘 중 선처리가 후처리에 영향을 주지 않는 병렬 세선화 알고리즘 중에서 ZS, LW, 및 WHF 알고리즘의 문제점을 찾아내었다. ZS 알고리즘은 사선 방향에서 화소가 손실되는 문제점을 안고 있으며, LW 알고리즘은 사선 방향에서의 화소 두께가 1이 되지 못하는 문제점을 내포하고 있다. 따라서 본 알고리즘에서는 사선 방향에서 8근방을 이루며, 화소의 두께도 완전히 1이 되도록 개선시킨 병렬 세선화 알고리즘을 제안한다.

TFD is a transcription factor database which consists of short functional DNA sequences called as signals and their references. SIGNAL SCAN, developed by Dan S. Prestridge, is used to determine what signals of TFD may exist in a DNA sequence. This program searches TFD database by using a simple algorithm for character string comparison. We developed TFSCAN that aims at searching for signals in an input DNA sequence more efficently than SIGNAL SCAN. Our algorithms consist of two parts, one constructs an automata by scanning sequences of rFD, the other searches for signals through this automata. Searching for signal-related references is radically improved in time by using an indexing method. Usage of TFSCAN is very simple and its output is obvious. We developed and installed a TFSCAN input form and a CGI program in GINet Web server, to use TFSCAN. The algorithm applying automata showed drastical results in improvement of computing time. This approach may apply to recognizing several biological patterns. We have been developing our algorithm to optimize the automata and to search more sensitively for signals.

Environmental protection and precaution are the most frequently considered issues in the recent research fields for our present and future surroundings. However, it seems that these environmental issues were less reflected in local-level development plans, and caused several cases of environmental pollution, therefore it became a major concern of local governments and the communities. The role of a 'Local EIA(Environment Impact Assessment)' can be a core issue for the positive preferences of the local-level development plans. Cases of Local EIA in Germany which have been implied successfully are reviewed to generate a local EIA movement and to produce a guideline for Korean local governments. The local EIA in Germany was broadly commenced in the middle of 1980s, and a decade later it was carried out for over 200 of local governments. To produce a better suggestion for Korean local EIA, comparison and analysis of detail data of the German local EIA was carried out, and tested for fourteen cities in Korea based on five categories: i) assessment subject, ii) assessment procedure, iii) main office for assessment, iv) assessment factor and v) assessment standard. Prior suggestions for greater preference of local EIA in Korea are: it is necessary that I) launch of a support system in central government to help the movement of local government; Ⅱ) a knowledge-based expert group in local government which has by all means of exclusive responsibility far any action(new application or performance of local EIA) : 111) establishment of 'environmental protection measure' in local government level for environmental precaution based on individual environmental character and values in their communities.

This study analyzed the expressive characteristics of padding in contemporary fashion. The methodology of this study was quantified through documentaries, fashion collections, and internet news. The results of expressive characteristics and methods were as follow. First, variability showed the creation of dwelling space by air filling, detail mode by zipper, and diversity of recycled filling by zipper pocket. It reflected the pursuit of nomadism and subversion of permanence by change of filling. Second, it was sexual symbolicity that showed the blurred androgynous silhouette by air filling and padding bar design of the chest, stomach, shoulder for the male body silhouette. It emphasized male sexual identity and power through the expression of a modern ideal body. Third, decoration displayed various crafts (such as knitting), various fabric such as polapolis, suedette, corduroy, denim, leather, knit, and spangle. It reflected visual pleasure, scarcity and various interpretations. Fourth, playfulness character forms throug hair filling, unfamiliar fashion items, diversity of silhouette and change of uses. It reflected a pleasant feeling through astonishment and surprise, nostalgia involved in memory and childhood play and disembarrassment from reality. Fifth, simplicity showed the elimination of a sportswear's factor with regular wad quilting, elimination of wad quilting, wad quilting following the structural line of clothes and the structual line of clothes omitted. It reflected disembarrassment from stereotype and an emphasis on essential elements.

This paper is within the framework of an adhered complete contact problem wherein the contact between a half plane and sharp edged indenter, both of which are elastic in character, is constituted. The eigensolutions of the contact shear and normal stresses, σ_rq and σ_q, respectively, are evaluated via asymptotic analysis. The ratio of σ_rq/σ_qq is investigated and compared with the coefficient of friction, μ, of the contact surface to observe the propensity to slip on the contact surface. Interestingly, there exists a region of |σ_rθ/σ_θθ| ≥ |μ|. Thus, slipping can occur, although the problem is solved under the condition of an adhered contact without slipping. Given that a tribological failure potentially occurs at the slipping region, it is important to determine the size of the slipping region. This aspect is also factored in the paper. A simple example of the adhered contact between two elastically dissimilar squares is considered. Finite element analysis is used to evaluate generalized stress intensity factors. Furthermore, it is repeatedly observed that slipping occurs on the contact surface although the size of it is extremely small compared with that of the contacting squares. Therefore, as a contribution to the field of contact mechanics, this problem must be further explained logically.

The purpose of this research was to investigate the impression dimension and to elucidate the image perception depending on the tone of the Korean jacket and Korean skirt using the tone-on-tone coloration. As stimulators, the became same color by making the skirt and jacket red, yellow, and green at the same time. After the skirt and jacket became four kinds of tones, vivid, light, dull, and dark by altering value and fuing chroma in the assembled color, these tone-on-tone coloration stimulators $48(3\times4\times4)$ were used for the investigation of this study. Impression factor of the stimulus consisted of the 5 different dimensions(youthfulness and activity, attractiveness, gracefulness, concentration of attention, tenderness). Among these factors, youthfulness and activity, attractiveness were proved to be more important. In the tone-on-tone coloration of a Korean skirt and a Korean jacket, each dimensional image was affected by the character of color, also the evaluation of countenance showed the meaningful difference depending on tone. Thus, we can comprehend that the influence of tone as well as color affects the evaluation of an image.
