  • 본 논문은 이전 연구에서 구현된 OnePIC 앱의 실행 성능과 저장 성능을 분석하여 OnePIC 앱의 실용성을 검증한다. OnePIC 앱은 다양한 초점을 가진 사진들을 촬영한 후, 원하는 초점의 사진을 얻을 수 있는 카메라 앱이다. 본 논문은 성능평가를 위해 거리별 다초점 촬영 시간과 객체별 다초점 촬영 시간을 세부적으로 분석하였다. 성능평가는 실제 스마트폰에서 실측하는 방식으로 진행되었다. 거리별 다초점 촬영 시간은 5장에 0.84초, 객체 감지 시간은 객체 개수와 관계없이 0.19초, 객체별 다초점 촬영 시간은 5장에 4.84초 정도로 측정되었다. 다초점 사진을 한 장에 저장한 All-in-JPEG 파일 크기와 각각 JPEG 파일로 저장한 경우를 비교한 결과, All-in-JPEG 파일 크기가 미묘하게 줄어 저장공간의 큰 이득은 없었다. 그렇지만 All-in-JPEG은 다초점 촬영된 사진들의 관리 면에서 매우 용이하다. 결론적으로 본 논문의 성능평가 결과, OnePIC 앱은 촬영 시간과 사진의 저장 크기 및 관리 면에서 실용적인 것으로 판단된다.

  • Since American Airlines's mileage program emerged in market, loyalty programs have gained popularity. Many companies have generated many kinds of reward cards in order to induce precious consumers. As a result, reward cards are very important in consumer goods market and become diversified. In spite of its importance, little is known about how these cards influence consumer's perception. The prior research has not focused on reward card types and psychological variables. Accordingly this research intends to investigate psychological variables such as transaction coupling and sunk cost perception. According to the theory of regulatory focus, promotion focus consumers would point to gain-nongain frame work, but prevention focus consumers would point to loss-nonloss frame work. The paper proved the effect of reward card types and regulatory focus on transaction coupling and sunk cost perception. Based on the results from 2(type of card : visible vs invisible) ${\times}$ 2(regulatory focus: promotion vs prevention) between-subjects factorial design experiments, we found that consumer's transaction coupling and sunk cost perception of visible reward card are better recognized than invisible reward card. In addition, the results show that there is a significant interaction effect between the type of reward card and regulatory focus. Specifically promotion focused consumers tend to reveal better perception than prevention focused consumers in use of invisible cards. However, prevention focused consumers tend to show better perception than promotion focused consumers in use of visible cards. These findings will contribute to significant academic development and practically useful help to marketing managers.

  • Purpose - Consumer behaviors or decision-making process has been changing recently as the consumer environment, including mobile everyday life, has changed. In view of this changing consumer smart environment, this study aims to investigate structural relation about the influence omni-channel propensity and regulatory focus on consideration set formation. Research design, data, and methodology - In order to proceed with this study, we review previous studies and setting hypotheses. The hypothesis was verified through a survey that was conducted for university students with experience in purchasing in less than three months. With reference to previous studies, operational definition was made for the questionnaire design. From 2018 Nov. to 2019 Feb. Survey was conducted on the panel consumers who purchase item within that period. 315 collected survey data were used to verify hypotheses except the data that had incorrect values. This data were used for SPSS/AMOS for confirm hypothesis which developed by researcher. Results - The results of this study are as follows. First, Consumers were considering a more heterogeneous alternatives if they were more omni-channel propensity in the process of forming consideration set. Second, Consumers were more conscious of the price if they were more omni-channel propensity Third, Consumers were considering a more newness alternatives if they were more omni-channel propensity in the process of forming consideration set. Meanwhile, The results of the study on regulatory focus and consideration set relationships are as follows. Consumers were considering a more heterogeneous alternatives if they were more promotion focus tendency in the process of forming consideration set. Second, Prevention focus tendency were more conscious of the price in the process of considering alternatives. Third, Consumers were considering a more newness alternatives if they were more promotion focus tendency. Conclusions - Depending on the changing consumer environment, the omni-channel propensity was shown to influence the formation of the consideration set. Also, Regulatory focus of consumers significantly influence to formation of consideration set. this study also contributes to the development of the theory as well as the practical approach with understanding consumer decision process on smart(mobile) environment.

  • 양화문 안의 강 양화사와 약 양화사가 전제적/비전제적 해석과 관련된 영향권 다툼의 과정에서도 약 양화사가 주어이든 목적어이든지 표면 형태에서 VP로부터 멀리 떨어져 있는 경우에는 전제적 해석만을 받게 되어 양화문에 중의성이 발생하지 않는다. 그런데 타동사의 목적어나 비대격 주어 등의 약 양화사가 초점에 민감한 경우에 비전제적 해석이 가능하게 되어 중의적인 문장이 될 수 있다고 본다. 표면구조상 VP 밖에 위치한 약 양화사라도 초점화되면, 초점투사를 통하여 논리 형태에서 형성된 초점의 영향권(초점 구문) 안에 들어있게 되며, 이때의 초점이 가지는 영향권은 핵 영향권과 일치한다. 즉, 초점은 안에 있는 약 양화사가 핵 영향권 안에서 비전제적으로 해석되도록 하는 동력으로 작용한다고 볼 수 있다.

  • In spoken language, the characteristics of prosodic realization are related to the meaning of utterance. The pitch pattern of an interrogative sentence which differs from that of declarative sentences can be considered in this respect.. If we consider the question-answer pair, we can find that the most important variation comes from the intended meaning of asking. In this paper, we experiment with four kinds of interrogative sentences and show that the difference in pitch patterns of interrogative sentences can be explained in relation to the focus phenomena that is, the differences of the boundary tones in interrogative sentences are due to the differences in the prosodic domain of focus. For a relevant explanation with the focus phenomena, we divided focus into the categories: emphatic focus, which plays a role in delivering the speaker's intended meaning for the sentence interpretation, and informational focus, delivers the central intended meaning of the utterance. The results can be summarized in three points. First, High boundary tone delivers the meaning of asking. Second, the realization of different boundary tones that are found in wh-question and alternative question are just phonetic variations caused by focusing. Third, the high rise boundary tone in echo questions is related to the meaning of surprise or incredulity, and this relation is a consensus of existing opinion, that is, the speaker's attitude of surprise can raise the pitch range. From these results we can distinguish between boundary type and phonetic variation, and we can also give appropriate meaning to the different boundary tones in interrogative sentences that have been regarded as merely a part of sentence type.

  • Objective: Attentional focus is one of the critical factors that has consistently been demonstrated to enhance motor performance and motor skill. Focusing attention on the inside of the body while engaging in a particular exercise is called internal focus (IF) and focus on the external environment is called external focus (EF). The purpose of this study was to identify effects of IF and EF of attention on postural balance in healthy school-aged children. Design: Cross-sectional study. Methods: Twenty-four healthy school-aged children participated in this study. School-aged children was defined as children ages 8-12 years old. They performed the one-legged standing with EF (focusing on the marker at the level of participants' chest and 150 cm away), IF (focusing the supporting feet), and control (no instruction) respectively. The order of the focus condition was randomly selected. The center of pressure (COP) range, distance, and velocity was measured to compare the effects of applying different attentional focuses in the three conditions. Results: The results of our study show that differences in COP range, distance, and velocity among groups were not significant between the different attentional focuses, although all variables of EF were smaller than IF. It is postulated that the reason for this may be that school school-aged children between 8-12 years old go through a transitional phase from IF to EF in effective motor learning. Conclusions: These findings reveal that the type of attentional focus did not have any effect on postural balance in healthy school-aged children.
