Drawing on mere exposure effect, we proposed that more exposure to a city, as measured by the number of channels of exposure, would increase familiarity, city image, and intention to visit that city. We conducted a survey of university students in seven Asian countries, asking them about a total of 14 cities, at least one from each of the surveyed countries. Exposure was found to be a significant antecedent and was most powerful when mediated by familiarity. Some types of exposure were stronger than others. Personal exposure, in the form of having visited a city or knowing someone who has, was the strongest type of exposure, with more than double the effect of media exposure. Social media, which is difficult to classify as either personal or media, was assessed separately and had a much smaller effect. The mere exposure effect exists whether the intention to visit a city is related to pleasure (tourism) or business.

목적: 한국을 비롯하여 세계에서 중국에 대한 비호감도는 매년 상승하고 있으며, 2022년 현재 세계인의 반중정서는 70%에 달하고 있다. 중국은 공공외교에 천문학적인 예산 편성을 했음에도 불구하고, 국가이미지 회복에 실패하고 있다. 국가이미지 상승을 위한 새로운 공공외교가 필요한 지금, 한국인 중국 유학생 유튜버 딤디(deemd)의 시청자들이 딤디의 중국 vlog 시청 이후 중국에 대해 우호적인 이미지를 형성하게 되는 것을 발견했다. 이에 본 연구에서는 딤디의 중국 vlog 시청이 중국 국가이미지 개선에 영향을 미치는지 확인해보고자 단순노출효과를 이론을 적용했다. 또한 국가이미지 개선이 중국으로의 방문의도 증가 및 중국 제품 구매로 이어지는 '후광효과(Halo effect)'를 일으키는지 알아보고자 한다. 방법: 본 연구에서 설정한 5개의 연구 가설 검증을 위해 설문을 실시했다. 설문 대상은 유튜버 딤디의 중국 vlog를 한 번이라도 시청한 경험이 있고, 중국 방문 경험이 없는 시청자로 편의 표집했다. 결과: 가설 검증 결과, 딤디의 중국 vlog 시청은 중국의 경제적 이미지 개선에 긍정적 영향을 미치는 것으로 나타났다. 즉, 딤디의 중국 vlog 시청이 빈번할수록 중국의 경제 이미지는 긍정적으로 변화했고, 이는 궁극적으로 중국으로의 방문의도와 중국제품 구매의도를 증대시키는 것으로 나타났다. 결론: 본 연구에서는 vlog시청과 국가이미지, 해당국가 방문의도와 해당국가 제품 구매의도의 관련성을 탐구함으로써 해외 대중에게 다가갈 수 있는 공공외교의 구체적 방향으로 다양한 콘텐츠를 활용한 미디어 외교의 가능성을 제시했다. 본 연구의 결과가 중국을 비롯한 비대면 공공외교의 시대에 필요한 새로운 디지털 미디어 외교에 대한 혜안을 제공할 수 있기를 기대한다.

A vital step in magnetic tape manufacturing is the surface modification of polymer substrate prior to ink application. A critical element for good adhesion of magnetic ink on polymeric substrate is the ability to join ink in cost-effective manner. Corona discharging is one of the effective methods of modifying polymer surface to improve adhesion while maintaining the desirable properties of the film itself. Surface treatment by corona which is exposure of film surface to electron or ion bombardment, rather than mere exposure to active species, like atomic oxygen or ozone, can enhance adhesion by removing contaminant, electret, roughening surface, and/or introducing reactive chemical groups. Reactive neutrals, ions, electron and photons generated during the corona treatment interact simultaneously with polymers to alter surface chemical composition, wettability, and thus film adhesion. However, it is highly recommended that extensive chains scission be avoided because it can lead to side-effect by forming sticky matter, resulting in dropouts. This paper reviews principles of surface preparation of polymer substrate by corona discharging. In addition, the experimental section provides a description of parameter optimization on corona discharging treatment and its side-effect. Experimental results are discussed in terms of surface wetting as determined by contact angle measurements.

We developed a facial image generating technique that can manipulate facial impressions. The present study applied this impression transferring method to higher-order impressions such as "elegance" or "attractiveness" and confirmed the psychological validity of this method using the semantic differential method. Subsequently, we applied this method to two types of cognitive experiments. First, we examined the contributions of texture and shape on the facial impressions by using those face images for which the impressions have already been quantitatively manipulated based on this method. Second, we used such stimuli to examine the effect of facial impressions and attractiveness on the "mere exposure effect." Thus, we concluded that the impression transfer vector method is an effective tool to quantitatively manipulate the facial impressions in various cognitive studies.

많은 연구에서 온라인 리뷰 유용성에 영향을 미치는 다양한 요인을 발견하였다. 기존 연구에서는 주로 온라인 리뷰와 관련되는 정량적(예: 평점) 및 정서적(예: 감성점수) 요인이 리뷰 유용성에 미치는 영향을 조사했다. 온라인 리뷰는 제목과 내용을 동시에 포함하고 있지만, 기존 연구는 주로 리뷰 내용에 중점을 두고 있다. 그러나 리뷰 제목을 고려하지 않고 단순히 리뷰 내용만을 고려하면 리뷰 유용성에 영향을 미치는 요인을 조사할 때 한계가 존재한다. 이에 따라 리뷰 제목과 내용을 모두 고려하는 연구가 주목받고 있지만, 대부분의 연구는 리뷰 유용성에 대한 리뷰 내용과 제목의 영향을 독립적으로 조사하였다. 이는 리뷰 제목과 내용 간의 일치성이 리뷰 유용성에 미치는 잠재적인 영향을 간과할 수 있다. 따라서 본 연구에서는 단순 노출 효과 이론을 통해 리뷰 제목과 내용 간의 텍스트 일치성이 리뷰 유용성에 미치는 영향을 확인하고, 정보 선명성, 리뷰 길이 및 정보원 신뢰성의 역할도 고려하였다. 분석 결과, 리뷰 제목과 내용 간의 텍스트 일치성은 리뷰 유용성에 부정적인 영향을 미치는 것을 확인하였다. 또한, 정보 선명성과 정보원 신뢰성은 리뷰 유용성에 대한 텍스트 일치성의 부정적인 영향을 완화한다는 것을 발견했다.

A ban on political podcasting during the General Elections 2006 in Singapore was justified by the Singaporean government on the grounds that the new medium had a greater power to influence voters than traditional modes of political discourse. A between-subjects controlled experiment was conducted to test whether podcasts of political speeches had a greater power to influence voters' evaluations of political candidates and likelihood of voting for them than online text-based transcripts of the same speeches. The study also examined whether mere exposure to political speeches online, irrespective of the modality, had an effect on voters' more general political preferences, i.e. the likelihood of support and voting for the opposition. The findings suggest that political podcasts were no more persuasive than text-based websites and that the effects on political preferences, if any, were likely due the exposure to political content online, not because of the nature of the medium. The implications of the findings are discussed.

As the popularity of Korean drama and celebrities in China, Korean fashion is becoming increasingly popular in the Chinese market. Although the effect of Korean drama on Chinse consumers' attitudes toward Korean products are known, little research has been conducted to understand the mechanisms underlying the impact of Korean drama on the development of consumer attitudes. Thus, this study examines how Chinese consumers' exposure to Korean dramas has influenced their attitudes towards Korean fashion products. Applying the similarity-attraction theory, the study explores the roles Chinese consumers' perceived similarities in appearance and values with Korean characters in TV dramas plays in the process of attitude development. Data was collected via an online survey and the responses of 317 Chinese consumers in their twenties were used for data analysis. The results of structural equation modeling show that exposure to Korean dramas has a direct impact on Chinese consumers' perceived appearance similarity, perceived value similarity, image of Korean people, and attitudes toward Korean fashion products-results that support the theory of mere exposure. In addition, the analysis demonstrates that perceived appearance similarity positively influences the image of Koreans among Chinese people, which, in turn, influences attitudes toward Korean fashion products, supporting the similarity-attraction theory. However, the effect of perceived value similarity on attitude toward Korean fashion products was not significant. The study concludes by describing its practical implications for the Korean fashion industry and presenting ideas for future research.

In this research, we explore whether mere exposure to external cues with vertical progress (e.g., moving upward or moving downward) can influence individuals' persistence to complete focal tasks. Drawing on the theory of embodied cognition, we propose that, a moving-upward (vs. downward) cue activates the abstract concept of difficulty, which is associated with the physical experience of climbing uphill (vs. downhill). Due to this association between moving uphill and difficulty, merely exposing individuals to the moving-upward cue can induce greater feeling of difficulty and this greater difficulty, in turn, reduce individuals' persistence, compared to exposing individuals to the moving-downward cue. Across three studies, we find supporting evidence for the effect of the external cues with vertical progress on individuals' performance both in physical tasks and in a cognitive task.

Experiments were carried out the phenomenal observation on effect of corona treated hotmelt laminating film in process of manufacture by 2 kinds of rolling speed and electric power variatons. Surface treatment by corona which is exposure of film surface to electron of ion bombardment, rather than mere exposure to active species, like atomic oxygen or ozone, can enhance adhesion by removing contaminant, electret, roughening surface, and introducing reactive chemical group. Reactive neutrals, ions, electron and photons generated during the corona treatment interact simultaneously with polymers to alter surface chemical composition, wettability, and thus film adhesion. However, it is highly recommended that extensive chains scission is avoided because it can lead to side-effect by forming sticky matter, resulting in dropouts. This paper reviews principles of surface preparation of polypropylene substrate by corona discharging. In addition, the experimental section provides a description of parameter optimization on corona discharging treatment and its side-effect. Experimental results are discussed in terms of surface wetting as determined by contact angle and SEM measurements. When the rolling speed of the film decreased from 1.666 [m / sec] to 0.083 [m / sec], contact angle decreased from $80[^{\circ}]$ to $64[^{\circ}]$, and the wettability was greatly improved. As the supply power increased from 0.4 [kVA] to 2 [kVA] at the corona discharge surface treatment, the contact angle decreased from $77[^{\circ}]$ to $65[^{\circ}]$, and the wettability was greatly improved.

This study uses digital imaging and communications in medicine (DICOM) files acquired after CT scan to obtain the absorbed dose distribution inside the body by using the patient's actual anatomical data; uses geometry and tracking (Geant)4 as a way to obtain the accurate absorbed dose distribution inside the body. This method is easier to establish the radioprotection plan through estimating the absorbed dose distribution inside the body compared to the evaluation of absorbed dose using thermo-luminescence dosimeter (TLD) with inferior reliability and accuracy because many variables act on result values with respect to the evaluation of the patient's absorbed dose distribution in diagnostic imaging and the evaluation of absorbed dose using phantom; can contribute to improving reliability accuracy and reproducibility; it makes significance in that it can implement the actual patient's absorbed dose distribution, not just mere estimation using mathematical phantom or humanoid phantom. When comparing the absorbed dose in polymethly methacrylate (PMMA) phantom measured in metal oxide semiconductor field effect transistor (MOSFET) dosimeter for verification of Geant4 and the result of Geant4 simulation, there was $0.46{\pm}4.69%$ ($15{\times}15cm^2$), and $-0.75{\pm}5.19%$ ($20{\times}20cm^2$) difference according to the depth. This study, through the simulation by means of Geant4, suggests a new way to calculate the actual dose of radiation exposure of patients through DICOM interface.
