  • When English language teachers are deciding on their priorities for teaching pronunciation, it is imperative to know what kind of differences and errors are most likely to interfere with communication, and what special problems particular first-language speakers will have with English pronunciation. In other words, phoneme discrimination skill is an integral part of speech processing for the EFL learners' learning to converse in English. Training using sound visualization technique can be effective in improving second language learners' perceptions and productions of segmental and suprasegmental speech contrasts. This study assessed the efficacy of a pronunciation training that provided visual feedback for EFL learners acquiring pitch and durational contrasts to produce and perceive English phonemic distinctions. The subjects' ability to produce and to perceive novel English words was tested in two contexts before and after training; words in isolation and words in sentences. In comparison with an untrained control group, trainees showed improved perceptual and productive performance, transferred their knowledge to new contexts, and maintained their improvement three months after training. These findings support the feasibility of learner-centered programs using sound visualization technique for English language pronunciation instruction.

  • The purpose of this study was to describe preschoolers' perceptions of fear from their own perspective. Qualitative data from 213 preschoolers 4 to 6 years of age were obtained by semi-structured interviews. The fear inventory was analyzed by content analysis and frequency. The most common fears of preschoolers in this study were fear of ferocious animals and imaginary figures, such as tigers, lions, snakes, spirits and ghosts. Fear of ghosts was the primary fear of both boys and girls. Results showed that most fears were caused by disgust-related visual images. Worry about injury and pain was another common pathway to fear. At-risk preschoolers scored significantly higher than normal preschoolers on fears of criticism and getting an injection.

  • In this paper, we have proposed a band stop filter (BSF) for pre-processing of image sequences before encoding. By pixel-wise temporal filtering of the image sequences using the BSF, the bandwidth and noise of the signal are reduced, while preserving the image quality in view of human visual perceptions. As a result, when compared to the original image sequences, te pre-filtered image sequence requires lower bit-rates for encoding, while there is not much degradation in quality. Also, it has been shown that the proposed BSF causes less smearing and blurring than the conventional recursive low pass filter for bandwidth and noise reductions.

  • This study examines how a model's pose that signals power influences consumers' recall ability of price information in advertisements. To extend prior findings on social judgments, we suggest that the direction of consumers' gaze and willingness to pay attention to the model vary depending on the model's pose. Study 1 explores how consumers' perception of the power of the model affects their price recall ability. In particular, consumers demonstrate better price recall for items displayed at the bottom of the ad when the model adopts a powerful pose and items displayed at the top when the model in the ad assumes a submissive pose. Study 2 investigates the influence of the perceived power of a model's pose on price recall depending on the visibility of the model's face and reveals that consumers demonstrate better price recall for items displayed at the top when the model's face is not visible even when the model adopts a powerful pose. Ultimately, this research provides new insights to help marketers identify ideal locations for displaying price information in ads. More theoretical and practical implications are also discussed.

  • 지각이란 다양한 감각기관을 통하여 시각, 청각, 촉각, 후각 등 주위 환경에 대한 정보를 습득하는 과정으로 뇌에 전달된 정보를 통합하고 해석하는 것을 의미한다. 이러한 지각된 정보를 바탕으로 상황에 적합한 정보를 효율적으로 사용하는 능력을 지각기술(perceptual skill)이라 하며, 스포츠에서 지각기술은 경기력 향상을 위한 중요한 요소로 작용한다. 따라서 많은 연구자들은 지각기술을 극대화하기 위하여 다양한 방법의 지각기술훈련 프로그램을 개발하고, 그 효과를 검증하려는 시도들이 진행되고 있다. 본 연구에서 소개하고 있는 지각기술훈련은 시지각에 중점을 둔 훈련 방법으로 미국이나 유럽에서 스포츠 경기력 향상을 위해 적용하는 훈련프로그램이다. 축구 페널티킥 상황에서 골키퍼에게 키커의 중요 단서(키커의 엉덩이-몸통, 발의 각도)를 바탕으로 지각기술훈련을 실시한 결과, 볼의 방향 예측 능력이 향상되었고, 테니스에서도 서버의 중요 단서(자세, 공, 라켓)에 대한 지각기술훈련을 실시한 결과, 서브 방향에 대한 예측능력이 향상되었다. 최근 지각기술훈련에 대한 연구가 활발하게 진행되고 있지만 아직까지는 연구의 수가 많지 않으며, 대부분이 실험실 상황에서의 연구로 실제 경기 상황에서의 활용에 대한 연구가 부족한 실정이다. 따라서 연구자들은 스포츠 경기력 향상을 위하여 지각기술훈련의 필요성을 검토하고, 그 효과에 대한 연구 방향을 포괄적으로 검토해 보는 시도가 필요하다.

  • This is a comparative study focused on the scenic landscape preferences derived from visitors's perceptions at the Dulle-gil and the uphill trail in Bukhansan National Park. Unlike previous landscape assessment methods, this study contains more direct and on-site analysis with methods of understanding the visitors' perceptions by using 'visitor employed photography(VEP)' which requires each visitor to take preferable scenic landscape with one's own smart phone camera. The scenic landscape types at two different trails were categorized and then the types favoring most of participants were verified. There are total number of 16 visual landscape types preferred by participants at both the Dulle-gil and the uphill trail in Bukhansan National Park. As in terms of consensus photography(CP) on the Dulle-gil was found to have more diverse elements including both natural and artificial elements compare to the uphill trail. Furthermore, the perceptually excited node(PEN) at the Dulle-gill were found to be more scattered evenly whereas PEN at the uphill trail were concentrated on the entrance and the top of the mountain. It is necessary to consider that the scenic landscape management at the Dulle-gil and the uphill trail require different approaches. Facilities were set based on careful consideration of distinctive geographical features and vegetation in the Dulle-gil. And the management need to be focus on the 'forested area' maintaining natural state in the uphill trail. Futhermore, the result of the CP and PEN in the trails would be helpful to proceed the next step of landscape perception study depending on characteristics of groups.

  • This study examines changes in consumer perceptions of fashion shows, which are critical elements in the apparel industry and a means to represent a brand's image and originality. For this purpose, big data in clothing marketing, text mining, semantic network analysis techniques were applied. This study aims to verify the effectiveness and significance of fashion shows in an effort to give directions for their future utilization. The study was conducted in two major stages. First, data collection with the key word, "fashion shows," was conducted across websites, including Naver and Daum between 2015 and 2018. The data collection period was divided into the first- and second-half periods. Next, Textom 3.0 was utilized for data refinement, text mining, and word clouding. The Ucinet 6.0 and NetDraw, were used for semantic network analysis, degree centrality, CONCOR analysis and also visualization. The level of interest in "models" was found to be the highest among the perception factors related to fashion shows in both periods. In the first-half period, the consumer interests focused on detailed visual stimulants such as model and clothing while in the second-half period, perceptions changed as the value of designers and brands were increasingly recognized over time. The findings of this study can be utilized as a tool to evaluate fashion shows, the apparel industry sectors, and the marketing methods. Additionally, it can also be used as a theoretical framework for big data analysis and as a basis of strategies and research in industrial developments.

  • Objectives: The aim of this qualitative study was to investigate how members of the general public in Korea interpret the concept of health, and which dimensions of health are most important to them. We also explored their perceptions of the EuroQoL 5-Dimension (EQ-5D), including the EuroQoL visual analogue scale (EQ-VAS). Methods: We conducted face-to-face, in-depth interviews with 20 individuals from the general population, using a semi-structured interview guide. Content analysis was performed with verbatim transcripts and field notes to identify codes and categorize them according to their similarities and associations. Results: In total, 734 different codes were derived and classified into 4 categories. Participants cited the importance of both the mental and physical aspects of health, although they emphasized that the physical aspects appeared to play a larger role in their conceptualization of health. Participants noted that the EQ-5D has the advantage of being composed of 5 dimensions that are simple and contain both physical and mental areas necessary to describe health. However, some of them mentioned the need to add more dimensions of mental health and social health. Participants showed great satisfaction with the visually well-presented EQ-VAS. However, participants opined that the EQ-VAS scores might not be comparable across respondents because of different ways of responding to the scale. Conclusions: While physical health is a fundamental aspect of health, mental and social aspects are also important to Koreans. The content of the EQ-5D broadly matched the attributes of health considered important by Koreans.

  • This study assessed the effectiveness of brand image communication on consumer perceptions of cruelty-free fashion brands. Brand messaging data were gathered from postings on the official Instagram accounts of three cruelty-free fashion brands and consumer perception data were gathered from Tweets containing keywords related to each brand. Web crawling and natural language processing were performed using Python and sentiment analysis was conducted using the BERT model. By analyzing Instagram content from Stella McCartney, Patagonia, and Freitag from their inception until 2021, this study found these brands all emphasize environmental aspects but with differing focuses: Stella McCartney on ecological conservation, Patagonia on an active outdoor image, and Freitag on upcycled products. Keyword analysis further indicated consumers perceive these brands in line with their brand messaging: Stella McCartney as high-end and eco-friendly, Patagonia as active and environmentally conscious, and Freitag as centered on recycling. Results based on the assessment of the alignment between brand-driven images and consumer-perceived images and the sentiment evaluation of the brand confirmed the outcomes of brand communication performance. The study revealed a correlation between brand image and positive consumer evaluations, indicating that higher alignment of ethical values leads to more positive consumer assessments. Given that consumers tend to prioritize search keywords over brand concepts, it's important for brands to focus on using visual imagery and promotions to effectively convey brand communication information. These findings highlight the importance of brand communication by emphasizing the connection between ethical brand images and consumer perceptions.
