Purpose: This study investigated the impact of key factors such as service quality, perceived benefit and brand familiarity on a consumer's intention to order online food delivery (OFD). In addition, mediating effect of electronic word of mouth (e-WOM) between relationships among selected key variables and OFD purchase intention is also assessed. Research design, data and methodology: This explanatory, quantitative study employed convenience sampling and collected data through online structured questionnaire from 304 respondents who are users of OFD apps based in greater Klang valley region of Malaysia. The data was then subjected to normality and reliability assessment followed by confirmatory factor analysis, validity assessment and structural equation modelling using IBM SPSS AMOS 24.0. Results: Findings revealed that service quality, perceived benefits and brand familiarity affects purchase intention positively and significantly. Perceived benefits demonstrated highest impact on purchase intention followed by brand familiarity and service quality. Findings also suggest that e-WOM fully mediates relationship between brand familiarity and purchase intention, however, the same was not observed for remaining two variables. Conclusions: The study has enriched OFD literature by investigating impact of selected key factors on purchase intention in the context of OFD. Implications, limitations and future research avenues are then discussed.

현재 디스플레이 기술의 급격한 발전과 종류의 다양성으로 인해 디스플레이 화질평가에 대한 중요성이 대두되고 있다. 기존 디스플레이 화질평가는 물리측정에 의한 정량적 평가법이 사용되어 왔지만, 이러한 방법은 최종 평가자인 인간의 인지평가와 일치하지 않는다. 따라서 이와 같은 모순점을 해결함과 동시에 디스플레이의 물리적 특성과 인간의 인지화질 사이의 정량적 상관관계를 정립할 필요가 있다. 이에 본 논문은 디스플레이들의 상대적 인지화질을 평가할 수 있는 체계화된 방법을 제안하며, 이 방법을 통해 디스플레이들의 상대적 인지화질을 정량화한다. 디스플레이들에 대한 상대적 인지화질평가는 개개인의 주관적 의사를 평가하는 것과 같으며, 이 점에 착안하여 디스플레이 인지화질평가에 의사결정방법들 중 하나인 Analytic Network Process(ANP)를 도입하였다. 또한, 본 논문은 인간의 시각정보처리 체계를 표현하기 위해서 색, 모양, 깊이에 해당하는 3가지 평가기준을 채택하였으며, 그 3가지 평가기준들에 대한 하위 평가항목들로 디스플레이의 대표적 특성 8가지를 사전 설문조사를 통해 선정하였다. 제안된 방법과 주관적 평가의 유사성을 입증하기 위해 대표적인 모바일 디스플레이인 TFT-LCD와 OLED 디스플레이에 대해 상대적 인지화질을 실험 평가하였다. 그 결과, 제안된 방법에 의해 정량화된 값들 사이의 대소관계와 주관적 평가를 통해 얻은 디스플레이 선호도 간의 관계가 유사하다는 것을 입증하였다.

This paper presents a methodology to nominate and select improvement projects that are perceived as adding value to customers (both internal and external). The structure of the methodology can be explained in three "stages." First, the methodology suggests a new way of categorizing improvement opportunities, i.e. reactive-proactive, to "upgrade" the little Q-big Q categorisation. Then, it develops a roadmap that links performance indicators and improvement projects for both reactive and proactive improvements. Finally, it suggests an algorithm to select the improvement project, where the assessment of to what extent the nominated improvement projects add value to customers relies on the comparison between Overall Perceived Benefits (OPB) and Overall Perceived Efforts (OPE). The improvement project perceived as having the largest impact on adding value to customers receives the highest priority.

This paper presents a detailed subjective quality assessment for the ultra-high definition (UHD) videos having frame rates of 30fps and 60 fps. The subjective assessment is based on the ITU-R BT-500 recommendations, where double stimulus continuous quality scale (DSCQS-type II) test is performed for the evaluation of the perceived quality of the user's in terms of differential mean opinion score (DMOS). Encoding of the UHD videos by opting encoders i.e. H.264/AVC, H.265/HEVC, and VP9 at five different quantization parameter (QP) levels is done to investigate the perceived user's quality of experience (QoE) given as DMOS. Moreover, the encoding efficiency as the encoding time for each encoder and qualitative performance by employing full-reference (FR) quality metrics are presented in this work.

Purpose: In this study, effects of positive, negative, and mixed verbal feedback were examined for accuracy of self-assessment, emotional responses, self-efficacy, and perceived quality of feedback in skill performance assessment. Methods: Participants were a convenience sample of 104 second-year nursing students who had completed their fundamentals of nursing class. Participants were assigned randomly to a positive, a negative or a mixed feedback group. All participants completed the performance measure and then received the assigned the type of feedback from an evaluator. After delivery of feedback, they assessed their own performance using the same sheet as the evaluator and completed the survey for emotional response, self-efficacy for learning, and quality of feedback. Results: There were no significant differences in accuracy of self-assessment and perceived quality of feedback among the three groups ($x^2=4.74$, p=.094; $x^2=3.30$, p=.192, respectively). The negative feedback group had significantly lower self-efficacy and positive emotions and more negative emotions than the other two groups (F=9.43, p=.009; $x^2=16.29$, p<.001; $x^2=5.69$, p=.005, respectively). Conclusion: Negative feedback can affect emotions and motivations for learning in nursing students and may interfere with the effectiveness of feedback, so instructors should pay more attention when providing negative feedback. Mixed feedback with an effect similar to positive feedback could be an alternative.

This paper will discuss the difference between self assessment of voice disorders and the hearer voice assessment of a comparative group of normal subjects. The study was conducted on 25 voice disorder subjects and 32 hearers of a comparative group of normal subjects. The results are as follows. Firstly, in K-VHI and VHI-H, the hearers of the comparative group of normal subjects perceived more serious voice disorders than the voice disorder group in all sub-domains. Likewise, in K-VQOL and VRQOL-H, the hearers of the comparative group of normal subjects perceived more serious voice disorders than the voice disorder group in all sub-domains. Secondly, the hearer voice assessment of the comparative group of normal subjects showed no difference in gender regarding the perception of the severity of voice disorder issues. Thirdly, the hearer voice assessment of the comparative group of normal subjects states that in the emotional aspects of VHI-H, professional voice users perceive more serious voice disorders than others. Accordingly, in VRQOL-H, there was no difference in use of the voice between professionals and others.
