Background and Objectives: Although many studies have evaluated the effect of the digital noise reduction (DNR) algorithm of hearing aids (HAs) on speech recognition, there are few studies on the effect of DNR on music perception. Therefore, we aimed to evaluate the effect of DNR on music, in addition to speech perception, using objective and subjective measurements. Subjects and Methods: Sixteen HA users participated in this study (58.00±10.44 years; 3 males and 13 females). The objective assessment of speech and music perception was based on the Korean version of the Clinical Assessment of Music Perception test and word and sentence recognition scores. Meanwhile, for the subjective assessment, the quality rating of speech and music as well as self-reported HA benefits were evaluated. Results: There was no improvement conferred with DNR of HAs on the objective assessment tests of speech and music perception. The pitch discrimination at 262 Hz in the DNR-off condition was better than that in the unaided condition (p=0.024); however, the unaided condition and the DNR-on conditions did not differ. In the Korean music background questionnaire, responses regarding ease of communication were better in the DNR-on condition than in the DNR-off condition (p=0.029). Conclusions: Speech and music perception or sound quality did not improve with the activation of DNR. However, DNR positively influenced the listener's subjective listening comfort. The DNR-off condition in HAs may be beneficial for pitch discrimination at some frequencies.

본 논문은 방송통신 융합미디어로 등장한 IPTV의 이용인식을 구체적으로 탐구하고 이를 바탕으로 IPTV 수용결정요인이 무엇인지 실증적으로 분석하였다. 혁신기술에 대한 이용자 인식을 지각된 유용성과 용이성으로 구분하여 이를 시스템적으로 측정하는 기술수용모델을 준거로 하고, 본 논문에서는 IPTV의 미디어적 특성을 반영한 지각된 오락성 개념을 추가함으로써 모델의 확장을 도모하였다. 그리고 IPTV 이용인식에 영향을 미치는 요인으로 개인적 요인(개혁적 성향, 자기효능감)과 환경적 요인(사회적 영향력, 비용의 영향력, 광고의 영향력)을 제시하여 다차원적인 영향요인들이 IPTV 이용인식에 어떤 영향을 미치며, 이를 토대로 IPTV 수용결정요인이 무엇인지 살펴보았다. KT와 SK브로드밴드 이용자 500명을 대상으로 한 온라인 서베이 결과, 다차원적인 영향요인들은 IPTV 이용인식에 긍정적인 영향을 미치고 있어 다양한 영향변인 탐색의 필요성을 제시할 수 있었다. 그리고 이용인식 중 지각된 용이성은 지각된 유용성과 오락성 인식에 긍정적인 영향을 미칠 뿐만 아니라 이용의도에도 높은 영향력을 나타내 IPTV의 수단적 부분의 향상이 확산을 유도하는 중요 변인임을 알 수 있었다. 또한 오락성 요인은 전체적 경로분석에서 높은 영향력을 주고 있어 시청각 미디어로서의 특성을 강화하는 것이 확산전략에 유의미함을 논의할 수 있었다. 본 논문은 근원적인 이용자 이용인식 탐구를 선행하여 IPTV 수용결정요인을 논의하였다는 측면에서 연구의 의미가 존재한다.

Digital signage in a smart store would engage and invoke responses from consumers because good in-store experiences are more important than ever. Thus, the present study investigates consumer perceptions of interactive digital signage integrating technology acceptance model. Specifically, the current study examined 1) the effects of personal and fashion innovativeness on interactivity; 2) the effect of interactivity on perceived usefulness, ease of use, and enjoyment; and 3) the effects of perceived usefulness, ease of use, and enjoyment on intentions to use the products and the store, visit the store, and engage in word-of-mouth. As a pre-study, two researchers visited the smart stores of six brands in Seoul, all of which integrate various technologies in the fashion field. A video clip was developed as a stimulus to the study. A total of 214 responses were gathered and analyzed. The results were as follows. Personal innovativeness has a significantly positive effect on interactivity, whereas fashion innovativeness has no significant effect. Interactivity had positive effects on the perceived usefulness, ease of use, and enjoyment. Consumer responses (i.e., intentions to use, visit, and engage in word-of-mouth) were predicted by usefulness and enjoyment, but not by ease of use. The findings of this study could provide the fashion industry and retailers practical and valuable insights into enhancing consumers' in-store experiences through the use of interactive digital signage.

Organizations have attempted to develop Knowledge Management Systems for achieving competitive advantage by effectively managing organizational knowledge. However, if Knowledge Management Systems are not user-oriented, organizations may not attain desired goals. That is, it must be utilized and accepted by organizational members to be successful systems. This study proposes an extended Technology Acceptance Model and empirically validates it. For that purpose, a research model is set UP that consists of antecedent variables, perception moderators, and intention to use the system. Empirical data analysis found significant relationships among research variables, as suggested in research hypotheses. The results of the analysis indicated that perceived usefulness, ease of use, job relevance and information quality should be considered as important factors in designing Knowledge Management Systems. In addition, perceived value, incentive, affect, self-efficacy, and image were found to influence the perception of users in the usage situation.

본 연구는 수학 교과 전문성 개발 필요에 대한 초등 교사의 인식을 탐색함으로써 수학 교과 전문성 개발의 개선 방향을 모색하였다. 이를 위해 초등학교에 재직 중인 초등교사를 포커스 그룹으로 구성하여 그룹 토의 자료를 수집하고 분석하였다. 연구 결과, 수학 교과 전문성 개발 필요에 대하여 초등 교사는 불필요와 필요하다는 인식을 모두 가지고 있는 것으로 나타났다. 수학 교과 전문성 개발이 불필요하다는 인식에는 초등학교 수학 교과 내용의 쉬운 수준과 초등학교 수학 수업의 용이함이 영향을 미치고 있었으며, 수학 교과 전문성 개발이 필요하다는 인식에 대해서는 수학 수업의 다양한 측면 고려, 수학 수업 실패의 누적, 학생에 대한 권위 유지, 사회 변화에 따른 수업 개선 요구, 학교 업무 수행의 영향, 교내 교사 학습 공동체의 영향, 동료 교사의 영향, 교사로의 성장을 위한 노력이 관련 요인으로 나타났다. 이를 바탕으로 수학 교과 전문성 개발에서 교사의 참여를 촉진할 수 있는 방안을 논의하였다.

Foodservice industry and distribution business could make mutual prpgress when they join forces in responding to environmental uncertainty in an efficient manner. The purpose of this study was to examine the relational characteristics of domestic food service businesses and distribution firms in conjunction with the distribution channels and ensuing conflicts between them, to present possible alternatives on and how they should communicate with each other to achieve a satisfactory result. The relational characteristics and ensuing conflicts of food service businesses and distribution firms appeared to be significantly characterized by incongruities of target, role and perception. The types of relational characteristics that were triggered by the disagreement of roles and perception combined to decrease the intensity of the relational commitment. A satisfactory transactional relationship served to ease their conflicts caused by perceptual disagreement, and the soos of conflicts that were rooted in the discord of roles and of perception that increased the degree of relational commitment. As for relational performance, relational commitment, satisfaction with distribution channel and satisfaction with suppliers allowed them to maintain their relationship on a long-term basis.

While the term online shopping refers to all online transactions, cross-border online shopping means shopping activities purchasing products or services over the internet for the customers abroad. As Internet use for the international shopping activity increasing, cross border online shopping has grown substantially for last decade. This study is about the problem regarding the cross border online shopping for two different countries and the variables that influence their shopping behavior. The cross border online shopping has been increased by the growth of Internet access. However, the growth of the Internet use does not guarantee a successful development of cross border e-commerce for every country. To find out the perception for cross-border online shopping for two different cultures, shoppers from two countries with different cultural background were chosen, and the perception for cross-border online shopping from each culture is contrasted. For statistical Analysis, ANOVA is used to find the relationship between a single non-metric independent variable, and multiple metric dependent variables. Hofstede's cultural dimensions model is adopted for this study as a tool to find out the patterns of cross border online shopping. This study showed what the variables would affect the perception in cross border online shopping. The results of this study indicated that cross border online shoppers with different culture were notably different on two variables identified-timeliness and ease of use.
