To study the antimicrobial effect of fluoride-releasing removable orthodontic appliances, 0 wt%(Group 1), 5 wt%(Group 2) and 10 wt%(Group 3) of $CaF_2$ were added to orthodontic resin. The specimens were then put in media in which S. mutans and Lactobacillus, known cariogenic bacteria, were cultured. Inhibiting zones were measured 24, 48 and 72 hours later. The following conclusions were reached: 1 In the Lactobacillus media, no zone of inhibition was observed regardless of the time passed. 2. In the S. mutans media, zones of inhibition were observed after 48 hours. 3. S. mutans showed greater inhibition in Group 3 compared to Group 2, after 72 hours rather than 48 hours(p<0.01).

An electret filter is composed of permanently charged electret fibers and is widely used in applications requiring high collection efficiency and low-pressure drop. In this work, the collection efficiency of the filter media used in manufacturing cabin air filters was investigated by using poly-disperse particles when submicron particles were loaded. Long-term experiments were conducted by applying two different charging states, which were spray electrification and charge equilibrium by bipolar ionization. In order to investigate the effect of particle loading in filter media, NaCl particles were generated from 0.1% and 1% solutions by an atomizer. Liquid DOS particles were used to evaluate the effect of liquid particles on the collection efficiency of an electret filter. The results show significant effect of charge amount and size distribution of loading particles on the collection performance of a filter media in submicron region. Smaller particles loaded in electret fibers cause a more rapid degradation in collection efficiency and have lower minimum efficiency with time. The pressure drop of a filter media do rarely increase when the collection efficiency decreases to the minimum value. For the larger particles charged by spray electrification, which have charge amounts more than that of Boltzmann equilibrium charge distribution, the pressure drop of a filter media slowly increases in comparison with that of equilibrium charged particles. For DOS particles it is shown that the charging level of an electret filter severely decreases and the collection efficiency is below 10% in some particle size range.

본 논문은 국내의 수용자들이 2006년 독일 월드컵 당시 한국의 매스미디어를 통해 관람한 월드컵 경기가 그들의 월드컵 후유증에 어떠한 영향을 미쳤는가를 분석하기 위한 것이다. 이를 위해, 2006년 한국과 16강 예선전을 펼쳤던 3개 국가와의 경기와 관련한 보도에 대한 응답자들의 미디어별 노출을 측정했으며, 직 간접적 차원의 월드컵 후유증에 대해 조사했다. 또한 순수한 미디어의 영향력을 검증하고자 응답자의 인구학적 특성과 스포츠 및 월드컵에 대한 호감도와 같은 가외 변인을 상정하여 측정했다. 계층 회귀 방법을 사용하여 일부 효과가 검증되었는데, 4대 매체 중 라디오가 간접적 후유증에 영향을 미친 것으로 분석되었다.

본 논문에서는 공연기획자가 공연 기획 시 어떠한 매체를 이용하면 효과적으로 광고와 홍보를 할 수 있을지 규명하고자 하였다. 관람 전(관람동기), 관람 과정(서비스품질), 관람 후(콘텐츠품질)의 3단계로 나누어 공연관람을 위한 구매의사에 미치는 영향을 알아본 후 매체별 유형에 대한 조절효과를 알아보았다. 분석 결과 연구자가 제시한 관람동기, 서비스품질, 콘텐츠품질이 구매의사에 유의한 영향을 미쳤고, 매체별 유형은 각 영향요인에 대해 조절효과를 가지고 있었다. 따라서 공연 기획의 모든 과정에서 다양한 광고매체를 이용하여 보다 효과적인 광고 및 홍보를 결정할 수 있도록 한다.

It has been known that spermatozoa should obtain their fertilizing ability through capacitation and acrosome reaction, and that in these processes of fertilization, Ca2+ platys an important role for their conjugation. Therefore the present study has been designed in order to clarify the effect of fluctuation of the media Ca2+ level and the intracellular concentration of the spermatozoa on the acrosomes. During the incubation of spermatozoa, a considerable fluctuation in the media Ca2+ level has been observed after the BSA administration and the media concentration of Ca2+. It is deduced that these fluctuation rates may have an effect on the acrosome reaction. The fluctuation of K+ flux has been observed in accordance with the incubation period over time, and it's concentration seems to be closely related with the acrosomal reaction. The respiratory exchange rate (RERI of the spermatozoa is kept more regular in the BSA and Cacl2 administration groups than the non-administration group. Based on the experimental findings, it is possible to deduce a hypothesis from these findings that physiological activities of the acrosome reaction are not functionally related to the media Ca2+ level and the intracellular influx of Ca2+ concentration, although Ca2+ platys an important role as a stimulating factor in the acrosome reaction.

Purpose: This study aimed to explore the variables that may play a significant role in inducing Facebook users to use Facebook as online information distribution channels continuously. Research design, data, and methodology: The population of this study are all Facebook users who have actively used Facebook as a social media as online information distribution for at least one year. Purposive sampling technique was used in this study and 290 respondents were enrolled. The data was collected using a questionnaire and further analyzed with path analysis and SEM-PLS approach. Result: The results showed that perceived ease of use, perceived critical mass, perceived enjoyment, and perceived information intelligence have a positive and a significant effect towards perceived usefulness. Perceived usefulness also has a positive and significant effect on users' attitude, and users' attitude has a positive and significant effect on intentions to use Facebook continuously among its users. Conclusions: Hence, it is important for Facebook as an online information distribution channel to maintain its perceived usefulness in order to create a positive impact on its users' and induce Facebook users' to use social media continuously.

The purpose of this study was to evaluate the effect of self-actualization and demographic variables of adult women on the modesty and aethetics in the selection of clothes. The qestionnaire were completed by 647 women in taegu and jinju. The major findings of this research can be summairzed as follows : 1. Marital status has effect on the self-actualizing values. religion, occupation and income have effect on self-acceptance. Marital staus and religion have effect on nature of man. 2. Frequency of contact with mass media has effect on the modesty of clothing. Self-actualization and demographic variables have no direct effect on the modesty of clothing. 3. Self-actualizing values, self-acceptance, nature of man, income, frequency of contact with mass media have direct effect on the aethetics of clothing.
