The Purpose of this study was to evaluate the effect of the shear bond strength between porcelain laminate veneer and enamel according to the surface treatment and thermocycling. Group Ⅰ, as a control group, was sandblasted only; group Ⅱ was sandblasted and etched; group Ⅲ was snadblasted and silane treated; and group Ⅳ was sandblasted, etched and silane treated. A porcelain block was placed onto the etched enamel under a 150g static load and the bonded site was light-cured from 4 directions for 1 minute each. The 72 bonded specimens were stored in water at 37℃ for 1 day. Half of each group were themocycled at 4℃ and 60℃ for 100 cycles with a dwelling time in each bath of 1 min. Following thermocycling, the specimens were installed in an Instron universal testing machine and the shear bond strength was measured. After the specimens were fractured, the fractured surfaces were examined with SEM. The obtained results were as follows; 1. The shear bond strength of the sandblasted and etched and silane treated group(Group Ⅳ) was the strongest of all, and the shear bond strengths between the snadblasted group (Group Ⅰ) and the sandblasted and silane treated group (Group Ⅲ) were not statistically different(p>0.05). 2. When the shear bond strength was measured after thermocycling, only the sandblasted, etched and silane treated group (Group Ⅳ) was statistically different (p<0.05). 3. The scanning electron microscopic views of the fractured surfaces show more irregularities and more resin fragments in the etched group than in the unetched group. 4. The scanning electron microscopic views of the fractured surfaces show a more delicate surface after thermocycling and after silane treatment than before thermocycling and before silane treatment. J.

In the view of the results investigated the effect of air pollutants that is emitted from a new generator facilities, the total estimated concentration which is the summation of a contributional concentration and observational concentration is much less than that of atmospheric environment criterion for the air pollutants. So we can predict that the operation of the new generator facilities with mitigation equipment don't seriously affect around environment. At the same time, we compared the contributional concentration of before mitigation equipment with that of after it to examine the decreasing amount due to mitigation equipment. The result showed that the concentration of SO2, NO2 and PM-10 is reduced to 25%, 30% and 26% of original value, respectively.

The purpose of this study is to estimate demand by type for individual complexes and analyze distribution characteristics by region to suggest policy directions in order to systematically manage the continuously increasing number of old apartment complexes in Busan Metropolitan City and revitalize remodeling projects. First, 2,384 apartment complexes in Busan were selected and basis data by age, floor area ratio, complex status, and zone were constructed. Based on this, the types were classified into reconstruction type, general maintenance type, customized remodeling, and furniture expansion type remodeling, and the demand for remodeling and maintenance business by region in Busan was estimated. As a result of the analysis, the demand for remodeling projects in the Busan region was high at 44.3% of the total, and there was a significant variation in demand creation in the distribution by region. Therefore, this study suggested policy directions for promoting remodeling projects and preparing step-by-step implementation plans in preparation for excess migration demand, taking into account the need to secure infrastructure for smooth project promotion, the need to establish specific public support plans for each type, and the spatial characteristics of each region.

The Role of Evaluative Language in News Translation : Focusing on Soft and Hard News

Ban, Hyun,Noh, Bokyung The International Promotion Agency of Culture Tech 2018 International Journal of Advanced Culture Technolo Vol.6 No.2

In the digital era, news consumption is not confined in geological boundaries. Technological advances bring the instant dissemination of news into life and allow news audience to consume events that occur far away almost in real time. The transmission has blurred the boundary between traditional media and new media, and the one between physical and virtual world. That is, what if a journalist applies news framing to the news translation process? This paper aims to investigate the gap between the ST and the TT created when the source news texts undergo a translation process. To achieve this aim, the appraisal theory developed by White (2003) is employed to identify a difference between the ST and the TT. Furthermore, we have attempted to identify differences between soft news stories and hard news stories while the STs from both news stories are translated into the TTs. Two time-sensitive events, Hugh Grant's marriage and a U.S. and North Korea summit, were selected. The former (a soft news story) is extracted from the Telegraph and the latter (a hard news story) is from the Washington post. As a result, it was found that such strategies as attitude, engagement, and judgment were used when the source news texts from the hard news story are translated into the target news texts. Under the appraisal theory, the strategies involve evaluative language which refers to positive or negative language that judges the worth of entities. In general, it is said that a journalist frames the SS (especially from the hard news story) to convey his ideology to news consumers. Hypothetically, we assume that a similar framing process takes place in deriving the TT from the SS of the hard news story. Thus, we could conclude that the TT from the hard news story differs from the TT from the soft news story and that the difference can be explained within the framework of White's appraisal theory.

Usage of Digital Mobile Communication and Change in a Traditional Media Use

Hyun Ban 한국방송학회 2004 한국방송학회 세미나 및 보고서 Vol.- No.-

Digital mobile communication(DMC) and its technologies have become an icon of digital convergence in broadcasting and telecommunication. Especially, Digital Mobile Broadcasting(DMB) service will provide us with various multimedia services, including network TV programs, movies, music videos, and so on. Under these circumstances, the purpose of this study was to examine (1) the effects of usage of DMC use on traditional media use(TMU); (2) the purpose of mobile phone use and satisfaction; (3) the users' perception of mobile phone and its services; and, finally, (4) the users' intention to use DMB services. To achieve the goals, the study conducted a survey among teenagers and young adolescents, aged from 10's to early 20's. The sampled individuals were male and female students who were considered the most powerful mobile-phone users. The results indicated that there was a significant positive relationship between usage of DMC and TMU, including TV, newspaper, Internet and the index of traditional media use. That is, the DMC did not replace the TMU, which showed the possibility that DMC can ""coevolve and coexist"" with the traditional media. A factor analysis was conducted to produce a total of 5 factors of the mobile phone users' motive: entertainment, sociality, fashion, instrumental and safety. These factors were used to further analyze the correlations with DMC. Particularly, the relationships between various mobile Internet services and the factors were strongly interrelated one another. Finally, the users' intention to use DMB services was low in general, although heavy users were more likely to use DMB service than light users of mobile-phone.

Identification of Targets of the HIF-1 Inhibitor IDF-11774 Using Alkyne-Conjugated Photoaffinity Probes

<P>We developed a hypoxia-inducible factor-1 (HIF-1) inhibitor, IDF-11774, as a clinical candidate for cancer therapy. To understand the mechanism of action of IDF-11774, we attempted to isolate target proteins of IDF-11774 using bioconjugated probes. Multifunctional chemical probes containing sites for click conjugation and photoaffinity labeling were designed and synthesized. After fluorescence and photoaffinity labeling of proteins, two-dimensional electrophoresis (2DE) was performed to isolate specific molecular targets of IDF-11774. Heat shock protein (HSP) 70 was identified as a target protein of IDF-11774. We revealed that IDF-11774 inhibited HSP70 chaperone activity by binding to its allosteric pocket, rather than the ATP-binding site in its nucleotide-binding domain (NBD). Moreover, IDF-11774 reduced the oxygen consumption rate (OCR) and ATP production, thereby increasing intracellular oxygen tension. This result suggests that the inhibition of HSP70 chaperone activity by IDF-11774 suppresses HIF-1 alpha refolding and stimulates HIF-1 alpha degradation. Taken together, these findings indicate that IDF-11774-derived chemical probes successfully identified IDF-11774's target molecule, HSP70, and elucidated the mode of action of IDF-11774 in inhibiting HSP70 chaperone activity and stimulating HIF-1 alpha degradation in cancer cells.</P>

Analyzing Quotations in News Reporting from Western Foreign Press: Focusing on Evaluative Language

Ban, Hyun,Noh, Bokyung The International Promotion Agency of Culture Tech 2016 International Journal of Advanced Culture Technolo Vol.4 No.3

This study explores evaluative linguistic expressions in news reporting about the 2016 general election outcome in Korean newspapers. In particular, we have examined the evaluative linguistic expressions quoted from the three Western news media -New York Times, Washington Post, and BBC, both quantitatively and qualitatively in Korean news stories in order to know how journalists frame the news stories to persuade news consumers to accept their ideologies. This is based on the assumption that quotation can be a tool in conveying ideologies to news consumers (van Dijk, 1988, Jullian, 2011). To achieve this purpose, we selected ten Korean newspapers which included quotations from the news stories of the three Western media and then analyzed the quoted expressions quantitatively and qualitatively. For a qualitative analysis, evaluative linguistic expressions were analyzed to examine the journalistic stances of the Western news stories, following Martin's (2003) appraisal theory. For a quantitative analysis, a word frequency analysis was conducted to figure out the ratio of quoted words to the whole news texts in Korean newspapers. As a result, it was found that the news stories of BBC and Washington Post were more frequently quoted than that of New York Times when journalists conveyed neutral or positive attitude to the election outcome, thus confirming that evaluative linguistic expressions were functionally employed to convey journalists' ideologies or stances to news readers.
