Not even in TV commercial advertisement, ASMR also fast growing in one-person media communication, many brands and social media influencers used ASMR for their marketing contents. The purpose of this study is to measure consumers' perceptions about the products in ASMR marketing content and compare the differences in communication effect of ASMR content creator between product review and how-to in the same Macro tier influencer - the YouTuber that has 10,000-100,000 subscribers. Design/methodology/approach The research methods selected ASMRtist that do product review content and how-to content, Text comments data was collected from 200 videos of tech-device review videos and beauty-fashion videos. A total of 52,833 text comments were analyzed by applying the LDA topic modeling algorithm and social network analysis. Findings Through the result, we can know that ASMR is good at taking attention of viewers with ASMR triggers. In the Tech device reviews field, ASMR viewers also focus on the product like product's performance and purchase. However, there are many topics related to reaction of ASMR sound, trigger, relaxation. In the Beauty-fashion field, viewers' topics mainly focus on the reaction of the ASMR trigger, response to ASMRtist and other topics are talking about makeup - fashion, product, purchase. From LDA result, many ASMR viewers comment that they feel more comfortable when watching the marketing content that uses ASMR. This result has shown that ASMR marketing contents have a good performance in terms of user watching experience, so applying ASMR can take more consumer intention. And the result of social network analysis showed that product review ASMRtist have a higher communication effectiveness than how-to ASMRtist in the same tier.

This paper investigates the effects of age, gender, and situational factors on take-over performance in automated driving. The existing automated driving systems still consider a driver as a fallback-ready user who is receptive to take-over requests. Thus, we need to understand the impact of situations and human factors on take-over performance. 34 drivers drove on a simulated track, consisting of one baseline and four event scenarios. The data, including the brake reaction time and the standard deviation of lane position, and physiological data, including the heart rate and skin conductance, were collected. The analysis was performed using repeated-measures ANOVA. The results showed that there were significant age, gender, and situational differences in the takeover performance and mental workload. Findings from this study indicated that older drivers may face risks due to their degraded driving performance, and female drivers may have a negative experience on automated driving.

Objective: The aim of this study is to investigate the gender-differences in vibrotactile responses(sensitivity and displeasure) of residual forearm simulated by vibration stimulation in upper limb(trans-radial) amputees. Background: Several studies have reported that vibration stimulation using the haptic vibrator is one the most effective methods for delivering sensation to an amputees. However, few studies have reported the perception to haptic vibratory stimulus, particularly sensitivity and displeasure. Method: We set up a custom-made vibration stimulation system that included 6 actuators(3 medial parts and 3 lateral parts) and a graphical user interface(GUI)-based acquisition system to investigate changes in residual somatosensory sensibility and displeasure in the forearm of upper limb(trans-radial) amputees. Vibration actuators were attached at the 25%-point on the proximal forearm. Stimulation with 32Hz, 64Hz, or 149Hz of frequency was used for the sensitivity tests and with 32~257Hz of frequency was used for the discomfort experiments. The subjective responses were evaluated on a 10 point scale. Results: The results showed that vibrotactile sensory perception in male amputees were higher than that in female amputees. In male amputees, the response at lateral area of forearm was the most sensitive than medial area; but, female amputees showed similar sensitive areas. Subjects did not experience any discomfort during vibrotactile stimuli. Conclusion: Vibrotactile response in the amputees was dependent on gender as well as area stimulated by vibration. Application: The results might contribute to develop the vibrotactile feedback system for the amputees.

본 연구는 백두대간 등산로가 지닌 자원과 이용의 특성, 등산이용에 따른 환경영향에 대한 등산객 인식을 파악함으로써 이용과 관리상의 현안과제를 도출하고 등산경험 제고와 보다 효과적인 백두대간 등산로 관리정책의 입안과 집행을 위한 자료를 제공하기 위한 목적으로 수행되었다. 이를 위해 백두대간 등산로를 입지와 지형적 특성을 고려한 3가지 유형으로 구분하여 각 구간별 이용행태와 등산객에 의해 발생할 수 있는 생태적, 물리적, 사회적 환경요소들의 영향수준에 대한 등산객의 인식을 분석하였다. 분석결과 이용행태는 구간별로 차이를 보이지 않았으며 백두대간 등산로는 휴양이나 여행과 같은 다목적의 이용보다는 순수한 등산의 목적지로 인식되고 있는 것으로 나타났다. 등산로 주변 생태적 환경은 이용 만족도와 상관관계를 보이지 않았으나 등산로 폭과 같은 물리적 환경의 변형은 백두대간 이용경험에 부정적 영향을 미치는 요인으로 나타났다. 사회적 환경 지표의 경우는 만족도와 상관관계가 없는 것으로 분석되었는데 이는 현행 백두대간 등산로의 이용밀도가 낮은 것에 기인한 결과로 판단된다. 백두대간 등산로의 생태적, 물리적, 사회적 환경에의 영향은 비교적 양호한 수준으로 현재까지 이용 경험의 질 저하는 나타나고 있지 않으나 향후 이용수준의 증가가 예상됨에 따라 제환경 영향요소간의 상호작용과 변화를 모니터할 수 있는 체계적 관리방안의 도입이 필요하다.
