It is generallybelieved that the values of female students are different depending on the cultural enviromment of society. The purpose of this paper is to discern the value orientation of female students in Korea and America, and how they are related to the clothing behavior. 300 female students were selected as sample from the Univ. of Minnesota and 158 students filled out the questionnair. 420 female students were selected from five unversities in Jinju, Taegy and Pusan. RESULTS : 1) Korean students had highly evaluated theaethetic, political, religious and social values, and American students had higher evaluation on the economic and American students had higher evaluation on the economic and theoretical values. 2) Korean students tended to regard modesty, conformity and management as important factors when they chose new clothes, and for American students, appearance and tool were important. 3) The impact of values on clothing vehavior was as follows. a) Korean students who emphasized theoretical values did not use clothes as an instrument of status symbol and modesty. b) American students who emphasized the economic values tended to have an interest in purchase and wearing of clothes on purpose. c) Korean students who had positive attitudes on the aethetic values tended to be conservative, but they wanted to use the clothes as a demonstration of self exaggeraton. d) Korean students who regarded social values important tended to have a higher interest in the management of clothes. e) Korean students who had highly evaluated the religious values tended to be conservative when the selected new clothes. American students did not want to conform to the group norm when they chose new clothes. On the whole, American students did not put on clothes to achieve a specific goal. In short, it can be concluded that Korean students and American students have different values and they have a great impact on their clothing behavior.

The purposes of this study are to identify the characteristics of limited edition fashion consumers, to analyze their purchase decision-making processes, and to examine negative factors of consumers' recognition toward limited edition fashion products. A qualitative investigation was conducted by doing in-depth interviews with 11 selected consumers in their twenties and thirties who have actively purchased and consumed limited edition fashion products. The results of this study can be summarized as follows. First, there are four sub-categories of appearance management activity, acceptance of fashion trend, information-seeking behavior, and hedonic shopping orientation for the limited edition fashion consumers' characteristics. Second, the purchase decision-making process of limited edition fashion consumers are identified as seven steps: need recognition, information search, evaluation of alternatives, planning and courtship, purchase, post-purchase evaluation, and post-purchase behavior. Courtship/attachment formation and post-purchase behavior are unique steps when compared to general purchase decision-making process. Third, this study identified negative factors of consumers' recognition toward limited edition this study in order to suggest several improvement plans for enterprises using limited marketing. Four sub-categories are examined: outrageous price, tricks of company, fatigue due to purchasing competition, and re-sellers. In conclusion, this study indicates that the purchase decision-making process of limited edition consumers, which involves two distinctive steps including courtship/attachment formation and post-purchase behavior, can be differentiated from general consumers. The results of this study provides preliminary data for further research for in-depth analysis of limited edition consumers.

Characterization of the UV oxidation for raw natural rubber (NR) was investigated in controlled conditions through image and FT-IR analysis. The UV oxidation was performed on a thin film of natural rubber coated on a KBr window at 254 nm and room temperature to exclude the thermal oxidation. Before or after exposure to UV light, image of the NR thin film was observed at a right or tilted angle. FT-IR absorption spectra were measured in transmission mode with the UV irradiation time. The UV oxidation of NR was examined by the changes of absorption peaks at 3425, 1717, 1084, 1477, 1377, and $833cm^{-1}$ which were assigned to hydroxyl group (-OH), carbonyl group (-C=O), carbon-oxygen bond (-C-O), methylene group $(-CH_2-)$, methyl group $(-CH_3)$, and cis-methine group $(cis-CCH_3=CH-)$, respectively. During the initial exposure period, the results indicated that the appearance of carbonyl group was directly related to the reduction of cis-methine group containing carbon-carbon double bond (-C=C-). Most of aldehydes or ketones from carbon-carbon double bonds were formed very fast by chain scission. A lot of long wide cracks with one orientation at regular intervals which resulted in consecutive chain scission were observed by image analysis. During all exposure periods, on the other hand, it was considered that the continuous increment of hydroxyl and carbonyl group was closely related to the decrement of methylene and methyl group in the allylic position. Therefore, two possible mechanisms for the UV oxidation of NR were suggested.

About vibration model of Six-degrees-of-freedom(DOF), in mass load, examined results for knowing dynamic interference and response variation is as follows; In case of putting mass load upon the object, experimented results on two-degrees-of-freedom of the translation-1 direction and the rotation-1 direction at open-loop-control system, about 0.19 arcsed in input of the translation-$0.1{\mu}m$ and $0.022{\mu}m$ on input of the rotation-0.5 arcsec, the justicse of motion equation is acknowledged as confirming the appearance of the interference-$0.022{\mu}m$. In establishing calculation of transformation matrix by using analogue circuit, as simulating results that used incomplete differentiation, interference is $1.7{\times}10^{-3}$ arcsec on input of the translation-$0.1{\mu}m$ and $1.4{\times}10^{4}{\mu}m$ on input of the rotation-0.5 arcsec in open-loop-control system. Also it is $4.2{\times}10^{-4}$ arcsec on input of the translation-$0.1{\mu}m$ and $5.6{\times}10^{-5}{\mu}m$ on input of the rotation-0.5 arcesc in closed-loop-control system. As closed-loop-control system is better than open-loop-control system, equivalent accordance is confirmed on original response. Finally, fundamental validity of this theory is acknowledged.

Objectives：The purpose of this study was to evaluate the variable sonographic features in addition to classic findings and to find the helpful characteristic findings for diagnosis of branchial cleft cysts. Subjects and Methods：We retrospectively analyzed the sonographic finding of 16 histopathologically proven branchial cleft cysts. Assessment involved the following variables : location related to carotid artery, size, cyst wall, border, margin, shape, internal echotexture, post echoic enhancement, orientation of longitudinal axis relative to the long axis of the neck, and tapering edge. Results：Most branchial cleft cysts were seen as well defined(15/16), oval shape(13/16), smooth inner (12/16) and outer margin(13/16), and post echoic enhancement(16/16). Their diameter varied from 1 to 6cm (mean 3.3cm). The branchial cleft cysts showed variable internal echopatterns；hyperechogenicity or pseudosolid appearance(1/16), heterogeneous echogenicity(4/16) in addition to classic form of anechoic(5/16) or hypoechoic internal echogenicity(6/16). Longitudinal axis of most branchial cleft cysts were arranged in the direction of the long axis of the neck(13/16) and some branchial cleft cysts had tapering edge(6/16). Conclusion：If both atypical sonographic findings and location are showed, longitudinal arrangement of long axis and tapering edge of branchial cleft cysts are helpful findings for differential diagnosis.

The limitations of food production caused by global warming, consumption of soil fertility, and land shortage have demanded the development of alternative foods. Their market has been increasing, and in particular, there is an urgent need for an alternative meat. Among them, the non-slaughtered cell-cultured meat that can be manufactured in the laboratory, that is, cultured meat, is in the spotlight, which can solve the problem of meat consumption while including the advantages of meat. It is classified into minced cultured meat and structured one with a structure similar to that of real meat. The latter is currently facing limitations related scaffolds, cells, and the multiplicative problems, and many attempts are being made to solve them. The complex problem is related to secure texture and taste as well as structural similarity to actual meat. To solve the problems, it is necessary to lay emphasis on cells, there are fat cells and vascular cells, and the most fundamental cells, muscle cells. These are the main cells that control the texture and nutrients of meat, and unlike other cells, they grow in the form of fibers. A myofibril (also known as a muscle fibril) is a basic rod-like organelle of a muscle cell, which is a quantitatively major component of meat, and one of the tissues that maintain the appearance of the body and bones. In this review article, we focused on the growth of muscle cells into long, tubular cells known as muscle fibers using the fabricated fibrous scaffold, and reviewed not only research results for muscle tissue engineering but also various results in the related fields for the last five years.

The increasing functional needs of top-quality printing papers and packaging paperboards, and especially the rapid developments in electronic printing processes and various computer printers during past few years, set new targets and requirements for modern paper quality. Most of these paper grades of today have relatively high filler content, are moderately or heavily calendered , and have many coating layers for the best appearance and performance. In practice, this means that many of the traditional quality assurance methods, mostly designed to measure papers made of pure. native pulp only, can not reliably (or at all) be used to analyze or rank the quality of modern papers. Hence, introduction of new measurement techniques is necessary to assure and further develop the paper quality today and in the future. Paper formation , i.e. small scale (millimeter scale) variation of basis weight, is the most important quality parameter of paper-making due to its influence on practically all the other quality properties of paper. The ideal paper would be completely uniform so that the basis weight of each small point (area) measured would be the same. In practice, of course, this is not possible because there always exists relatively large local variations in paper. However, these small scale basis weight variations are the major reason for many other quality problems, including calender blacking uneven coating result, uneven printing result, etc. The traditionally used visual inspection or optical measurement of the paper does not give us a reliable understanding of the material variations in the paper because in modern paper making process the optical behavior of paper is strongly affected by using e.g. fillers, dye or coating colors. Futhermore, the opacity (optical density) of the paper is changed at different process stages like wet pressing and calendering. The greatest advantage of using beta transmission method to measure paper formation is that it can be very reliably calibrated to measure true basis weight variation of all kinds of paper and board, independently on sample basis weight or paper grade. This gives us the possibility to measure, compare and judge papers made of different raw materials, different color, or even to measure heavily calendered, coated or printed papers. Scientific research of paper physics has shown that the orientation of the top layer (paper surface) fibers of the sheet paly the key role in paper curling and cockling , causing the typical practical problems (paper jam) with modern fax and copy machines, electronic printing , etc. On the other hand, the fiber orientation at the surface and middle layer of the sheet controls the bending stiffness of paperboard . Therefore, a reliable measurement of paper surface fiber orientation gives us a magnificent tool to investigate and predict paper curling and coclking tendency, and provides the necessary information to finetune, the manufacturing process for optimum quality. many papers, especially heavily calendered and coated grades, do resist liquid and gas penetration very much, bing beyond the measurement range of the traditional instruments or resulting invonveniently long measuring time per sample . The increased surface hardness and use of filler minerals and mechanical pulp make a reliable, nonleaking sample contact to the measurement head a challenge of its own. Paper surface coating causes, as expected, a layer which has completely different permeability characteristics compared to the other layer of the sheet. The latest developments in sensor technologies have made it possible to reliably measure gas flow in well controlled conditions, allowing us to investigate the gas penetration of open structures, such as cigarette paper, tissue or sack paper, and in the low permeability range analyze even fully greaseproof papers, silicon papers, heavily coated papers and boards or even detect defects in barrier coatings ! Even nitrogen or helium may be used as the gas, giving us completely new possibilities to rank the products or to find correlation to critical process or converting parameters. All the modern paper machines include many on-line measuring instruments which are used to give the necessary information for automatic process control systems. hence, the reliability of this information obtained from different sensors is vital for good optimizing and process stability. If any of these on-line sensors do not operate perfectly ass planned (having even small measurement error or malfunction ), the process control will set the machine to operate away from the optimum , resulting loss of profit or eventual problems in quality or runnability. To assure optimum operation of the paper machines, a novel quality assurance policy for the on-line measurements has been developed, including control procedures utilizing traceable, accredited standards for the best reliability and performance.

Under the pressure of the selection of topics and the presentation rules of mass media, politics in media society increasingly resort to professionalized forms of theatrical staging as a means of self-portrayal. Although these staging methods are not contradictory to what is actually going on in politics, they strongly advantage the tendency to focus exclusively on the staging of an event. Through their competition for public attention, politicians have been developing sophistication regarding placement and staging of events as well as regarding factual information. In the process of this transformation, politics that are issue-related and based on binding decisions are being gradually transformed into symbolic politics. Moreover, through their appearance on TV, politicians first of all need to possess presentational skills which are not necessarily related to their political achievements. Still, presentational skills decide over the success in politics of those politicians. The reason is that a politician who possesses presentational skills is still being perceived as being successful even if his political achievements notedly lag behind. On the other hand, political achievements are being underrated if a politician lacks the talent to present himself in front of the media. “The staging of politics, “politainment”, on the stage of mass media is evolving into a key structure which is responsible for a new coinage of politics in all different kinds of dimensions: the selection of staff, the role of action programs and their impact for the legitimation of political acting, even in relation to therole of pivotal political institutions such as parties and parliaments in the political process. The TV debates during the Bundestag elections of the year 2002 and 2005 are being analyzed and judged as “staging of politics”(politainment). Self-dramatization in media society concerning media discourses about politics and political self-portrayal has become a basic principle of political communication. Self-dramatization is a vital challenge for adequate political communication and content-based orientation in our present media democracies.

The recent problems of adolescents are leading us to amphasize school mental health program. Therefore, for the first step of that program, this study was attempted to find out the students' daily life stress, their adaptation beharior to resolve that stress, and their self-concept which has an effect on that beharior, to analyze the relationship among those three variables, and to provide basic data which help maintain and promote students' adaptability and mental health. The subjects were 4 classes each grade, 743 students who were chosen as a sample subject among the total of 3,250 students of a junior girls' school in Seoul by stratified sampling method. The Oquestionnair surrey was done from April 1, 1985 to April 6, 1985. The instruments were (1) a part of Junghoon chois' perceptual Orientation Scale for measuring self-perception of students, (2) Rosenberg's Questionnair for measuring students' evaluation of self-esteem, (3) modified Bell's Adoptive Behavior Questionnair, and (4) the Measuring scale for stress developed by the investigator. The collected data were analyzed by using descriptive statistics, x²-test, t-test, ANOVA, and Pearsons' Correlation. The results are summarized as follows: 1. The range of mean score of self-concept, stress, and adaptation beharior is 1-5 respectively. The mean score of self concept was 3.45. The mean score of stress was 2.53, and the degree of stress was in order of the problem of study and grade marks, girl friend, appearance, and relaxation. The subjects preferred effective long-term adaptation method (Mean=2.81) to ineffective short-term adaptation method. (Mean=2.47) 2. The self-concept had the highest degree when students were 1st grade, in good health condition, taking high grade marks, both parents existing, fathers' educational level being above college, and being in high economic status. The degree of stress was significantly high when students were 3rd grade, in poor health condition, having low grade marks, being in poor economic status, and fathers' educational level being under elimentary school. In relation with adaptation method, 1st grade students used more sbort-term and long-term method, and when students had high grade marks, being in high economic status. they used more long-term adaptation behavior. 3. Two Hypotheses of this research were tested: Hypothesis 1. "The higher the students' self-concept is, the more they use long-term adaptation method." was accepted. (r=.2482, p<.01) (t=-4.99, p<.001) Hypothesis 2. "The higher the students' stress is, the more they use short-term adaptation method." was accepted. (r=.2897, p<.01) (t= -7.51, p<.001) In conclusion, a person in charge of school health can help students to adapt effectively by planning and implementing methods which highten their self-concept and lower their stress. But because the correlation among self-concept, stress and adaptation behavior was at a low level, I think that the study, which confirm the relationship of those three variables, is needed.

Oral-Performance in itself, which successfully narrates one's life, constitutes a kind of decent Verbal arts. The term 'Sijipsali-Narrative' refers to oral narratives portraying a series of events in the course of Women's Life-Story which arise from family life and socio-cultural issues through marriage. As a result, Sijipsali-Narrative belongs to a subcategory of Women's Life-Story. Sijipsali-Narrative can be divided into two categories as follow. One type of Sijipsali-Narrative is the 'Family-Connection sijipsali-narrative,' which results from the relationship between a daughter-in-law and the rest members of the family. Among the 'Family-Connection sijipsali-narratives,' including several forms of Sijipsali such as that of father-in-law and that of husband and that of children, Sijipsali of the mother-in-law is most distinctive. The other type of Sijipsali-Narrative is 'Sociocultural-Connection Sijipsali-narrative', which comes not from human relationship but from general issues a narrator is suffering from as a daughter-in-law in a family. The most universal narrative comes from Sijipsali connected with poverty and historical events, and family history, appearance, attitude of the daughter-in-law and so on can be materials for the narratives. Actually, the two types of Sijipsali narrative is not so much distinguished from each other as intermingled with each other. Sijipsali arising from family relationship can inevitably be related with poverty and some events, which result in conflicts among family members and so harass daughter-in-laws. This thesis has a clear-cut orientation to overview the aspects of the Relationships and Hardships on a 'Sijipsali' Narratives in Korean Women's Married Life.
