This study aims to study the discourses influencing high school students' concept and attitude toward mathematics, and to examine how gender differences concerning mathematical aptitude are created. This study is based on the results of previous two studies which suggested that mathematical competence differs not only according to gender, region and school year, but also even within the same gender. For this study, 12 students ranking in the top 10% at two co-ed high schools were interviewed to find out 1) what discourses are related to gender and mathematics, 2) in what way these discourses are formulated and gain currency, and 3) how they have affected students in general. Common notions concerning mathematics may be summed up as follows: 1) Most of the students believe that gender difference in mathematical aptitude results because biologically men tend to be strong in mathematics and analytical skills while women tend to have better linguistic ability. This concept can help male students' studying to have a greater learning toward mathematics. 2) A large number of the students believe that male students' studying method is based on comprehension whereas female students' method is based on retention, and hence the former group tends to be better at applying their learning than the latter group. This notion seres to encourage male students and discourage female students from tackling difficult mathematical problems. 3) Many students believe that, although female students may surpass their male counterparts in middle school or the first year of high school, they will eventually fall behind by the 3rd year. Despite research which shows that these common beliefs are not grounded in scientific proof, high-school girls, who may be strong in mathematics, lose self-confidence and feel a sense of crisis. The mechanisms which produce and reinforce such concepts as those mentioned above can be summarized as follows: 1) Regarding the choice of majors and future career paths, parents show different attitudes toward sons and daughters, and this tends to influence high-school girls and hinders them from entering mathematics-related fields. 2) Teachers with value systems based on stereo-typed gender roles affect students a great deal, and give different advice according to gender of their students, for selecting their major fields - for instance, whether to study the natural sciences as opposed to humanities. 3) This study indicates that peer-group behavior, of either support or exclusion, also reinforces the process of internalizing notions of gender difference related to mathematical aptitude. 4) The gender-based notion that men are naturally more inclined to have better mathematical ability has caused male students to choose the natural science subjects and female students to turn to the humanities. The discourses discussed above, propagated in schools and homes, and in the mass media, are continually reinforced along with general gender inequalities in the society at large.

In this study, the problems In the current HDTV programming strategies were critically inquired into and reform measures were sought through in-depth interview with HDTV programming staff and program directors of the three major terrestrial broadcasting systems that are in their fourth year of HDTV broadcasting, and through analysis of the characteristics of HDTV programming. The analysis of this study showed that the time allocated to HDTV programs far exceeded the thirteen hours per week set by the Korean Broadcasting Commission. However, the percentage of HDTV programs broadcasted during the prime time was low, which as a result, limited the opportunity for the audiences to experience HDTV. furthermore, the low percentage of programs such as documentaries, sports, movies, etc. that are preferred by early adopters and through which the features of HDTV including high quality of picture, wide screen, etc. can be fully applied and shown did not appear to help in accelerating the popularization of HDTV In order to improve these problems, despite their having to bear the initial production costs, the broadcasting systems must come up with an aggressive strategies for the programming of documentaries, sports programs and dramas in order to strengthen the competitiveness in HDTV production and secure future adopters, and together with this, full support from the policy planning authorities and companies manufacturing electric home appliances, the other leaders in DTTB(Digital Terrestrial Television Broadcasting) transition, are necessary in order to promote the production of HD contents.

Some artists and scientists in physics and animation originating from research on its form of expression thanks to the rapid development of the example in the late 20th century image production technology integrating existing media feature, perform a re-creation and pop culture content has been recognized as a key factor. animation of the modern emphasis is also commercial and artistic activities as show whether the artist can not be excluded that also target audience. The audience does not want only to receive offers simply 'seeing' and 'hearing' in the animation requires a more indirect mental met. the other side, the director should lead the audience to immerse myself in work as intended mystification induce the world. where a conflict occurs between the audience and the director and The director needs to have its troubleshooting point to 'Technology of the communication'. Which is reduced to 'How will tell,' is technology communication technologies that are abbreviated representations of animation director is accessible to the audience and it is a close relationship between the psychological aspect of audience. Because, the audience is reproduced in a limited space, but he called on the board of directors and the same time the screen, the audience located at reception and the director located at provide. It is given. led force is given to the director. for this reason, The director needs to pay attention to the psychological aspect of audience this can be explained based on psychoanalytic theory. In this paper, "How can you lie to the audience and the director is the same line?" put down logic that is the animation audience under the logic that takes place visually capture phenomenon "selective attention" and sub-concept of "goal-directed selection' and 'stimulus-driven capturel' for theory of psychology. also, Induction device to elicit selective attention of the audience accordingly, let's consider whether and how they apply in animation.

UCC, an abbreviation for User Created Contents, is not only a symbol of desire but also a product of creativity that a producer contains his or her subjective disposition. More and more UCC tend to have significantly increased in Web 2.0 environment. However, the research on the contents as a creative product has rarely been processed. It may be fairly said that this results in the indifference of researchers in the special field like the political contents since UCC is usually produced by amateurs. Producers' various desire is unlikely revealed, which leads to the flow of users into open media such as the Internet. It could also be available to represent the property, of plural visual language signs in a field. Moreover, UCC has the attribute of re-mediation in effective communication, so the differences between the semiotic properties in the Internet contents could be a significant material for researches. This could contribute to establish a theoretical system for the visual communication. Therefore, this study aims to analyse the signification of the political video UCC, . To develop this analysis, I apply Greimas' Generative Trajectory of Signification Theory to the text, or the UCC. He classifies it as three structures: deep structure, superficial structure, and discourse structure. As a result, the text shows meaningful contents delivering core political messages. In addition, this approach could exam that 'Obama Syndrome' in American recent presidential campaigns is caused by web 2.0 based on Internet campaigns including video UCC.

The purpose of this study was to survey the degree of awareness and practice concerning prenatal care among Korean women. In this study, 626women in Seoul, Sungnam City, and Yangju Kun were randomly selected to be given a questionare that was formulated by the researcher. The statistical analysis of the data was obtained by percentage scores and $X^2$ scores on each item by age, educational background, and regional areas. The general out come of the study were as follows. A. The Practice of Prenatal Care 1. Physical Activities: Concerning the hard work, about a half of the women took care of it by themselves, and the others treated it with help. Also it was found that they tried to reduce the amount of travel as much as possible during pregnancy. 2. Dietary Intake: It was revealed that no significant change were observed before and during pregnancy. 3. Drugs: It was revealed that they tried to avoid drugs as much as possible during pregnancy. 4. Emotion: About a half of the women said that the family atmosphere did not change before and during pregnancy. The others said it had improved after pregnancy. In their spare time, most pregnant women rested in bed, read books, and listened to music. 5. Husband's Support: Most of the women expressed that they needed thief-husband's support absolutely, especially with hard work. They moderated the sexual activities when they found that they were pregnant. B. Degree of awareness for Prenatal Care 1. Perception of Prenatal Care: Most women heard about prenatal care at least one time through family, friend, or mass-media. 2. Necessity of Prenatal Care: Most women recognized the necessity of prenatal care, and they thought that the relaxation of body and mind was important during pregnancy. 3. Influence of Prenatal Care: It was revealed that most women recognized the positive influence of prenatal care to the neonate. 4. Practice of Prenatal Care: It shown that the most of pregnant women took serious interest in prenatal care and they tended to be careful during pregnancy. Generally speaking, the difference in educational background seemed to affect most to the pregnant women's awareness and practice of prenatal care: the higher the educational achievement, the more cautious about the prenatal care. The difference in region seemed to affect considerably in most aspects of practice: women in urban areas preceeded the rural women in prenatal care. The age difference seemed to affect least in their prenatal care except the younger generation took more care in avoiding the use of drugs.

This experimental research explores the effect of low attention of movie audience on the experience of presence, the degree of emotional touch, and memory about movie contents, because of indiscreet use of smart phone. This study measured and analyzed the experience frequency of presence, degree of emotional touch and recognition memory about movie contents by self report survey, after showing 2 subject groups consisting of 83 University students, one with not manipulated attention, the other with manipulated attention, using smart phone intentionally. This research found that the subjects exposed to the movie with not manipulated attention showed more presence experiences, and higher degree of emotional touch than the subjects exposed to the movie with manipulated attention. However meaningful difference of recognition memory was not discovered between the 2 groups. The result of this research can have a meaning because proceeding studies about presence effect of movie mainly dealt with the effect of HDTV, 3D image, stereo sound on the experience of presence, arousal, pleasure of movie audience and it is difficult to find studies about the relation between attention of movie audience and the experience of presence, emotional touch, and memory.

This study approached the elderly in Korea with a systematic review to find out the effect of virtual reality program arbitration on balance, which the evidence for the virtual reality program is provided. Total of 94 papers were searched through the database Nuri Media (DBpia), Scholarship (earticle), Korean Studies Information (KISS), National Digital Science Library (NDSL), the Korea Educational Research and Information Service (RISS), Kyobo Book Scholar (RISS), and Hakjisa New Thesis on Literature Selection using PRISMA flow-chart from January 2005 to May 2020 based on the final literature selection process and analysis. The quality level of the literature was found to be three volumes (50.0%) of the base level I, one (16.7%) of the II, and two of the III (33.3%). The most common type of virtual reality program was Wii-fit balance of 4 (66.7%), and the effect of virtual reality program arbitration was significant overall through evaluation tools for balance and walking ability. This is expected to effectively apply the virtual reality program to the elderly. In addition, since clinical application basis has been provided, further studies applying various virtual reality program interventions need to be addressed.

Understanding of the social perception of biotechnology would facilitate the public awareness and debate over the social implications of biotechnology, leading to strengthened basis for social consensus. As a part of the ELSI (Ehical, Legal and Social Implications) project in Korea, the authors have launched a series of social surveys on the social perception of biotechnology. This article is based on the analysis of the first survey, conducted in October 2001. The data were collected through telephone survey on 500 adult respondents nationwide selected by a stratified sampling method. The survey addresses the following questions: What is the present state of public awareness and attitude toward a variety of medical and social applications of biotechnology, such as genetic testing, prenatal genetic screening and testing, xenotransplant, genetic screening for employment, central collection and management of genetic information, and GM food? What factors are related with this perception? The analysis shows that a majority of respondents are in favor of the medical applications. Concerning the social applications and GM food, however, the respondents express a high level of negative attitude a with significant portion of 'do not know' responses. The public perception of the biotechnology is not crystallized in coherent manner yet. The public perception is strongly influenced by mass media, which tend to deliver rather positive information on biotechnology. The analysis suggests that the production and dissemination of diverse information should be activated to reach a sound decision on controversial issues surrounding the development of biotechnology both at individual and societal level as well.

Recently, as DNR prevails more and more in Korea, discussions regarding meaningless medical life-sustaining-treatment (LST) intensified. Some of the Supreme Court decisions are even discussed in mass media, causing public debates. These cases tell us that, as life-sustaining medical technologies are highly developed, more sociological and policy-related analyses are needed on them. Firstly, this study will review 40 previous studies that analyze recent discussions in Korea about LST. Secondly, this study also shows that in bioethical and policy-related perspectives, governance about LST calls for a new implications regarding thanatoethics and thanatopolitics. In this new theoretical framework, death with dignity (DwD) can be understood as a process of giving back the thanatopower to the subject who chooses his way of ending based on his sound and free will. Thirdly, some of the new LST or resuscitation technologies such as automated external defibrillators (AED) are developed in RRI framework. However, if subjects themselves choose not to apply those technologies on them, as in the case of DNR (do not resuscitate) vows, meaning of developing such technologies are to be questioned. But currently such questions regarding the limitations of RRI are seldom asked. I argue that in order to properly apply RRI framework on existing technology, we also need to consider these points.

This essay examines the motivations, goals, and assumptions of those who are participating in the appropriate technology movement in contemporary South Korea. In addition to analyzing books, articles, presentation materials, and media reports written by or about the "appropriate technologists," I have interviewed a few of them to hear their thoughts on appropriate technologies as well as inappropriate technologies. They choose to work on appropriate technology out of their good will for people in need, their Christian faith, and their pride in Korea's rapid and successful development. As a result, the appropriate technology movement in Korea does not engage in a critical evaluation of current sociotechnical systems, but instead takes an ethical and paternalistic stance in accepting and improving the given situation. Its apolitical character is effective in drawing a large number of participants, but it also limits their imagination and the movement's potential influence. Moreover, the movement's focus on "the other 90%" leads the participants to frame appropriate technology as something for "them" or "locals" rather than as something for "all of us." This essay concludes by suggesting that the appropriate technology movement in Korea should expand its scope from an ethical pursuit of technology to a political engagement with technology.
