본고에서는 2020년에 수집된 자유 발화 자료를 바탕으로 어두 폐쇄음 평음, 격음, 경음의 발화가 어떻게 달라지고 있는지 그리고 지각은 어떻게 이루어지고 있는지에 대해 자세히 살펴보았다. 기존 연구의 통제된 실험에서와 다르게, 자유 발화에서는 30대 남성까지도 VOT(voice onset time)에 의해 평음과 격음의 변별이 이루어지지 않았다. 지각실험은 언어 변화의 주도 계층인 젊은 여성 세대를 대상으로 하였다. 그 결과 어두 폐쇄음의 지각에서 F0이 평음과 나머지 둘을 변별하는 역할을 하였고, 그 다음 VOT가 격음과 경음을 변별하는 역할을 하였다. 특히 F0이 낮을 때에는 VOT의 길이가 짧든 길든 간에 항상 평음으로 지각되었다는 점은 평음의 지각에서 F0이 절대적인 역할을 한다는 것을 보여주었다. 그러나 어떤 F0의 경우에는 VOT에 따라 평음과 격음이 변별되기도 하였는데, 이는 20대 여성의 발화와 지각 체계가 일치하지 않기 때문이다. 음 변화의 관점에서 발화와 지각 체계가 일치하지 않는다는 것은 음 변화가 진행 중이라는 것을 의미하는데, 특히 20대 여성에서처럼 발화의 변화가 지각의 변화에 앞서는 경우는 음 변화가 후반 단계에 있을 때이다. 이처럼 언어 변화를 주도하는 계층에서 여전히 지각에서 이전의 체계를 유지하고 있는 이유는 그들의 부모 세대의 발화에서 VOT에 의한 평음과 격음의 변별이 이루어졌기 때문이며 이를 습득한 것이라고 볼 수 있다. 즉 다른 집단과의 소통을 위해 여전히 VOT를 지각에 사용하고 있는 것이다.

This experimental study has a goal to explore the perceptual sensitivity to phonetic evidence such as duration, phrase accent, or pause in disambiguation. We argue that the realization of the intonational phrasal boundary at the meaningful grammatical boundary in structurally ambiguous sentences facilitates English native listeners to distinguish the meanings of the ambiguous sentences. Moreover, the duration of the phrase-final syllable, pitch range reset, or phrasal tones also provides listeners with important phonetic evidence in disambiguation. In our perception experiment, however, Korean English learners largely depend on the realization of pause. In the results from the perception experiment, all of the groups showed an increase in the response time from the perception of no pause to pause realization. This means that pause at the phonological phrasal boundary plays a role of facilitator to English native speakers with other prosodic cues such as duration, pitch accent, or phrasal tones, while an absolutely important cue to Korean English learners.

In order to implement the real-time enterprise (RTE) and smart work effectively, many companies have introduced a mobile office. A mobile office improves employee productivity and increases ability to respond to business opportunities by helping employee manage their business anytime and anywhere. However, it also raises the user's stress level. We conducted in-depth interviews with users to assess user's perception of a mobile office according to Saaty's BOCR model. Based on the results of the interviews, we set variables affecting user's perception of the mobile office using factor analysis. This study revealed that support for real-time business, support for communication and collaboration, and information processing quality were positively related to continuous intention to use mobile office. Further study demonstrated that three variables have mediating effect between the psychological stress and continuous intention to use. This result implies that the system quality and function are the key elements of mobile office and may contribute to the continuous use.

It is easier to objectify the designing process with the analysis of how users perceive any space depending on the purpose of space visiting in the interactions of them and images. This study analyzed the observation characteristics perceived through observation frequency and time depending on the purpose cafe customers to understand what effect the design factors constructing the space has on the observation characteristics which are the results obtained as information through visual perception. The followings are the results of this study. First, The time range for searching or wandering and the observation characteristics could be estimated by the meaning of observation time by grade with the setup of time-range out of the distribution of sections. Second, at the time distribution by section, when there was intention, the observation time was found to have higher occupation. Third, though the higher section frequency is likely to have more observation time, the grades of II/V had higher frequency of [Intention] and the time had higher [Non-Intention], which revealed that there is a tendency for the observation characteristics vary in a large degree depending on whether there was intention or not. Fourth, by the application of the observation characteristics of each grade for interrelation analysis depending on whether there is any intention to the space of cafe, the detailed space characteristics could be compared with observation tendency. The difference of obtained information has an effect on obtaining perceived information, and since the intention may affect any information which is obtained, it is necessary for design information suitable to visit purpose or users' observation intention to be transferred in the process of designing. Analyzing the effect of any change to designing factors on the sight inducing intention and synchronization will help to understand the emotional design focused on users.

크기, 속도, 시간 항등성은 이차원 망막상의 오차에도 불구하고 삼차원 공간 속 대상을 일관적으로 지각할 수 있도록 돕는 기제이다. 이 기제들은 공통적인 단서를 바탕으로 동작하며 이는 운동거리, 운동속도, 운동시간의 지각이 공통된 처리 과정을 공유할 가능성을 시사한다. 따라서 시각자극의 공간적 특성이 시간지각을 왜곡시킴에도 불구하고, 환경 속에서 운동하는 물체에서 관찰되는 바와 동일하게 운동속도 지각과 운동시간 지각이 서로 반대되는 경향성을 보일 것이라는 가설을 세울 수 있다. 본 연구는 이 가설을 검증하기 위하여 뮐러-라이어 착시 자극을 사용하여 지각된 속도를 측정하여, 선행연구에서 관찰된 운동자극의 시간지각 결과와 본 연구에서 측정한 속도지각 사이의 관계를 규명하였다. 실험 1은 망막상 운동거리를 동일하게 유지하고 지각된 운동거리를 조작하였고, 실험 2는 망막상 운동거리를 조작하여 지각된 운동거리를 동일하게 유지하였다. 그 결과 이동거리가 실제보다 더 길게 지각되는 외측 유도자극에 비해 이동거리가 더 짧게 지각되는 내측 유도자극의 지각된 속도가 증가했다. 이 결과를 외측 유도자극에서 내측 유도자극보다 지각된 움직임 지속시간이 과대추정 되었던 선행연구와 연결지어 정리하자면, 뮐러-라이어 착시에 의하여 조작된 자극의 지각된 운동거리가 일정할 때 지각된 운동시간이 증가하면 지각된 운동속도가 줄어들고, 지각된 운동시간이 줄어들면 지각된 운동속도가 증가한다. 이 관계는 공간단서에 의하여 지각된 시간 및 속도 사이의 관계가 환경 속에서 운동하는 물체가 가지는 속성, 즉 운동거리를 동일하게 유지하였을 때 운동시간이 증가하면 속도가 감소하고 운동시간이 감소하면 속도가 증가하는 관계에 대응함을 시사한다.

This research paper looks into the interrelationships between physical self-perception, performance confidence, physical self-efficacy, dance flow and dance performance satisfaction with dance major students as the central figure. It also looks into the needs of dance majors, and in order to understand the accomplishment in dance and performance satisfaction, studies were carried out on 313 dance major students. According to this research, firstly, in the difference from physical self-perception according to general characteristics, specialists that major in dance have perception about one's body when specialists have a longer dancing time and experience. In the relationship between dancing experience and self-efficacy it could be seen that self-efficacy is postirely comelated with dancing experience. Also, in dance performance satisfaction, the more experience or time one encounters dance the higher the satisfaction. Secondly, when looking at the effect physical self-perception has on performance, confidence and self-efficacy, among the lower factors of physical self-perception, sports competence, condition and fitness have notable amount of effect on performance confidence. Thirdly, when looking at the effect on physical self-perception and self-efficacy, sports competence and condition have a certain amount of influence on body competence. Also sports competence, condition and fitness have some influence on physical confidence. Fourth, when looking at the influence of performance confidence and self-efficacy on dance flow, performance confidence, body competence and physical attraction have some effect on behavioral devotion. Lastry looking at the influence dance flow has on dance performance satisfaction, only behavioral devotion has much influence on dance performance satisfaction.

This study was conducted to check the cabin crew's safety perception in relation to the airline's safety climate and cabin crew's safety action and to verify that the safety perception's mediation effects. The results of the study confirmed that all three factors of the safety climate have a significant impact on safety perception, and among them, safety practice is the most significant. Accordingly, Airlines need to establish a community that enables real-time information exchange for air accidents so that the cabin crew can present real-time examples of safety-related accidents. In addition, it will be necessary to work with external safety agencies to form an active attitude for the establishment of safety procedures in order to prevent recurrence of safety problems while considering the causes of such incidents internally in the event of an airline safety accident. In addition, it was confirmed that safety training was the most significant factor to safety action, among which all three elements of the safety climate had a significant effect on safety action. Therefore, airlines need to expand practical training on aircraft to full-scale safety training to build an immediate resolution for cabin crews in the event of an air accident. In addition, safety training should be established to encourage collaboration among aviation safety-related personnel to participate in safety training together to address aviation safety from a diverse point of view. Safety perception was has a significant effect on safe action. Therefore, airlines should reinforce the airline's safety management system by checking the status of the cabin crew's safety perception extending the level of punishment to the scope of retirement or disqualification to establish a firm awareness of safety. Finally, the safety perception has demonstrated partial mediation effects in relation to the safety climate and safety action. Therefore, the airline needs to improve the duties of the cabin crew that interferes with cabin safety duties. In addition, airlines should utilize advertisements emphasizing that safety is first.
