This study examined the effects of media exposure and involvement on objectified body consciousness and appearance management behaviors. The subjects were 325 female university students in Daejeon and Chungnam Province. The research method was a survey, and the questionnaire was composed of media exposure and involvement, objectified body consciousness, appearance management behaviors, and subjects' demographic characteristics. The data were analyzed by descriptive statistics, Cronbach's ${\alpha}$, factor analysis, and regression analysis using SPSS program. The results were as follows. First, female university students used mass media for about 3.76 hours a day and showed a high level of media involvement. Second, three factors (body surveillance, body shame, and appearance control belief) emerged regarding objectified body consciousness with female university students showing a high level of objectified body consciousness. Third, six factors (make-up, plastic surgery, weight control, fashion, hair, and skin care) emerged regarding appearance management behaviors with female university students showing high intention to perform various appearance management behaviors. Fourth, media exposure and involvement had important effects on objectified body consciousness and appearance management behaviors, and media involvement was a more important variable than media exposure. Fifth, objectified body consciousness had important effects on appearance management behaviors. Body shame had more important effects on skin care, weight control, and plastic surgery behaviors, while body surveillance had more important effects on fashion, make-up, and hair management behaviors than other objectified consciousness factors. The implication of this study was that media involvement is a more important variable affecting objectified body consciousness and appearance management behaviors than media exposure, and among objectified body consciousness dimensions, body shame has important effects on more active appearance management behaviors like weight control and plastic surgery behaviors.

Industrialization and modern developments have led to an influx of toxic heavy metals into the aquatic environment, and the accumulation of heavy metals has serious adverse effects on humans. Among the various heavy metal treatment methods, adsorption is very useful and frequently used. Plastic materials, such as polypropylene and polyethylene, have been widely used as filter media due to their mechanical and chemical stability. However, the surface of plastic material is inert and therefore the adsorption capability of heavy metals is very limited. In this study, granular media and fiber media composed of polypropylene and polyethylene are used, and the surface modification was conducted in order to increase adsorption capability toward heavy metals. Oxygen plasma generated hydroxyl groups on the surface of the media to activate the surface, and then acrylic acid was synthesized on the surface. The grafted carboxyl group was confirmed by FT-IR and SEM. Heavy metal adsorption capability of pristine and surface modified adsorbents was also evaluated. Overall, heavy metal adsorption capability was increased by surface modification due to electrostatic interaction between the carboxyl groups and heavy metal ions. Fibrous PP/PE showed lower improvement compared to granular PP media because pore blockage occurred by the surface modification step, thereby inhibiting mass transfer.

폐수 처리를 위한 PVA 포괄 고정화 담체의 특성에 관한 연구를 실시하였다. 특히 PVA의 고정화 조건에 따른 용해도의 영향, 첨가제가 PVA 물성에 미치는 영향, 제작된 PVA gel의 질산화 처리 효율을 살펴보았다. PVA gel 제작 과정 중 진공을 걸어줄수록 그리고 동결온도가 낮을수록 PVA gel의 용해도는 감소하였다. PAC와 같은 첨가제를 넣었을 때 PVA gel의 용해도는 감소하였고 특히 organoclay를 넣었을 때 PAC에 비하여 25% 낮은 용해도를 보였다. 질산화 효율면에서는 PVA로 코팅한 담체가 기존의 부착 담체에 비하여 용질과 산소 확산의 제한 때문에 질산화율이 낮게 관찰되었다.

Reducing fear of cancer is significant in developing cancer screening interventions, but the levels of fear may vary depending on the degrees of media exposure as well as individuals' socioeconomic positions (SEP). However, few studies have examined how the SEP influences the fear of cancer under the moderating process of general and specific forms of media exposure. We investigated the moderating effect of media exposure on the relationship between SEP and the level of fear of cancer by assuming that cancer knowledge is a covariate between those two. In particular, this study examined how exposure to both general and specific media changes the series of processes from SEP to fear of cancer. We conducted path analyses with three types of media - television, radio and the Internet- using data from a health communication survey of 613 adults in Massachusetts in the United States. We found that SEP influences cancer knowledge directly and fear of cancer indirectly, as moderated by the level of media exposure. Health-specific exposure, however, had a more consistent effect than general media exposure in lowering the fear of cancer by increasing knowledge about cancer. A higher level of health-specific exposure and greater amount of cancer knowledge lessened the fear of cancer. In addition, the more people were exposed to health information on television and the Internet, the lower the level of fear of cancer as a result. These findings indicate a relationship between SEP and fear of cancer, as moderated by the level and type of media exposure. Furthermore, the findings suggest that for early detection or cancer prevention strategies, health communication approaches through mass media need to be considered.

Objective: In vitro culture of preimplantation embryos is improved by grouping embryos together in a drop of media. Individually cultured embryos are deprived of paracrine factors; with this in mind, we investigated whether the addition of a single embryo-secreted factor, interleukin-6 (IL-6), could improve the development of individually cultured embryos. Methods: Mouse embryos were cultured individually in $2{\mu}L$ of G1/G2 media in 5% oxygen and supplemented with a range of doses of recombinant mouse or human IL-6. Results: Mouse IL-6 increased hatching at doses of 0.01 and 10 ng/mL compared to the control (93% and 93% vs. 78%, p< 0.05) and increased the total number of cells at a dose of 0.1 ng/mL compared to the control ($101.95{\pm}3.36$ vs. $91.31{\pm}3.33$, p< 0.05). In contrast, the highest dose of 100 ng/mL reduced the total number of cells ($79.86{\pm}3.29$, p< 0.05). Supplementation with human IL-6 had a different effect, with no change in hatching or total cell numbers, but an increase in the percentage of inner cell mass per embryo at doses of 0.1, 1, and 100 ng/mL compared to the control ($22.9%{\pm}1.1%$, $23.3%{\pm}1.1%$, and $23.1%{\pm}1.1%$ vs. $19.5%{\pm}1.0%$, p< 0.05). Conclusion: These data show that IL-6 improved mouse embryo development when cultured individually in complex media; however, an excess of IL-6 may be detrimental. Additionally, these data indicate that there is some cross-species benefit of human IL-6 for mouse embryos, but possibly through a different mechanism than for mouse IL-6.

This study aimed to compare the perception of dental role-play or dental ASMR videos between the general public and dental personnel, to determine whether they are suitable for mass media or educational media, and to identify guidelines for video production. The survey consent form was agreed on using SNS for the general public and dental personnel, 236 ordinary people and 232 dental officers who said that they watched dental ASMR videos were analyzed. The questionnaire consisted of 27 questions for the general public and 31 for dental personnel. Data were analyzed using the chi-square test and the Independent T-test using SPSS 25.0 ver. The viewing experience of 'dental ASMR videos' was significantly higher among dentists (84.7%) than among the general population (71.5%) (p<0.001). Overall, 53.8% of the general public were interested in watching dental ASMR videos, and 47.8% of dental personnel acquired clinical information from them.. Overall, 64.8% of the general public and 65.5% of the dental workforce felt that such technical videos should be produced under the guidance of experts in the field to provide accurate technical information. It is necessary to avoid indiscriminate video production with inaccurate information produced by non-experts and to continuously monitor dental ASMR videos dental institutions for better quality of the videos.

The purpose of this study is to show the textile designers how to be creative and how to accept other ideas which are not necessarily of their own, and to show what exactly creating anything means. During the 1950's and'60s. America and Europe reached their peak in developing their consumption culture. After World War II, America achieved an astonished feat in developing its thechnology and industry to cause the economy to a rapid ascendence. The U.S. government adopted the Keynsian theory in its economic policy. The Keynsian theory advocates the consumer spending. And during this time period the American public developed consumption habit. Mass production and mass media went in hand to induce the public to buy. The public became an important target for the advertising stratages of the industry. In order for the industry to advertise the mass produced products, it had to utilize the mass media such as television, newspaper, and magazine. And mass media came into play an important role not to advertise the products, but to imform and educate the public about the products. This corporate stratege is further enhanced by the desire of the American public to climb up the ladder by way of material possession. Pop Art was born not only in reflecting the ideology of the consumption culture, but acted as a catalyst for more spending. The subjects of Pop Art are cars, foods, comics, Hollywood actors and movie scenes, the famous singers or persons. Andy Warhol specifically used the chosen image repeatedly to emphasize the redundacy of the image. The common factors which exist between Andy Warhol's Pop Art and textile design is the repetition in form, and the way of transferring an image to a canvas - Warhol used the frotttage technique to transfer an image to a canvas and textile design is transferred to a paper by way of transferring technique. Also the way Warhol thought of his paintings as a decorative elements and made a couple of his paintings into wallpapers or exhibits his painstings wall to wall demonstrates his close alliance with the textile design, let alone his comercial design background. In this study, I examined the inter-relationship between textile design and Pop Art. To carry out this study, I examined the comsumption culture: and the biomorphic relationship of culture and art: and Pop art and its transience stage. The major finding of this study is there exists a common denomenator between textile design and Pop Art, especially of Andy Warhol's.
