  • In this paper, we investigate and analyze the problems encountered in frame-based estimation of TDOA(Time Difference of Arrival) using CPSP function. Spectral leakage occurring in framing of a speech signal by a rectangular window makes estimation of CPSP spectrum inaccurate. Framing with a Hamming window to reduce the spectral leakage effect distorts the signal due to the different weighting at temporally same sample, which make the TDOA estimation using CPSP function inaccurate. In this paper, we solve this problem by reducing the dynamic range of the spectrum of a speech signal with preemphasis. Experimental results confirm that the framing of pre-emphasized microphone output with a rectangular window shows higher success ratio of TDOA estimation than any other framing methods.

  • This study intended to empirically verify the effect of message framing, cognitive need for closure, and type of fashion products on purchasing attitude of PB fashion products in discount stores. The design consisted of three-mixed design of 2(POP(Point of Purchase)message framing: benefit message vs. loss message) ${\times}2$(cognitive need for closure: high vs. low) ${\times}2$(PB fashion product type: utilitarian vs. hedonic). Survey of this study was conducted on 330 men and women in 20~50's in Seoul and Gyeong-gi, and a total of 287 data were analyzed. Data were analyzed with SPSS 18.0 program, and three-way ANOVA, simple interaction effects and simple main effects analysis were conducted. The results of this study are as follows: First, it was identified that the framing type of POP message of discount store, cognitive need for closure, and PB fashion product type had significant effect on preference and purchase intention. Secondly, it was identified that consumers with both high and low cognitive need for closure had high preference level and purchase intention when they encountered the benefit message framing than the loss message framing. Thirdly, the benefit message framing was more effective than the loss message framing for hedonic PB fashion products in discount stores, but utilitarian PB fashion products did not get affected by the message framing. Fourthly, it was identified that groups with both high and low cognitive need for closure preferred hedonic PB fashion products. Lastly, it was verified that benefit message framing POP advertisement on a group with high cognitive need for closure was effective for Hedonic PB fashion products in discount stores, and utilitarian PB fashion products showed no difference in purchase intention according to the POP message framing type and cognitive need for closure.

  • We define mathematical learning as a process of overcoming framing difference of teachers and students, two main subjects in a mathematics class. We have reached this definition to the effect that we can grasp a mathematical classroom per so and understand students' mathematical learning in the context. We could clearly understand the process in which the framing differences are overcome by analyzing mutual negotiation of informants in specific cultural models, both in its form as well as in its meaning. We review both of the direct and indirect forms of negotiation while keeping track of 'evolution of subject' in terms of content of negotiation. More specifically, we discuss direct negotiation briefly and review indirect negotiation from three distinct themes of (1) argument structure, (2) revoicing, and (3) development patterns and narrative structure of proof. In addition, we describe the content of negotiation under the title of 'Evolution of Subject.' We found that major modes of mutual negotiation are inter-reference and appropriation while the product of continued negotiation is inter-resemblance.

  • This research presented the privatization of pubic corporations in terms of communication dimension rather than political and ideological dimension. Concretely, we examined how the message framing of privatization affects consumer's advertising attitude. At the same time, this study also examined the moderating factors which make a difference of the message framing, such as personal relevance(high/low) and social value orientation(proself/prosocial). The results showed that the interaction effect between type of message framing and personal relevance. Positive message framing showed a higher effect than negative message in the case of low personal relevance. Also, There was the interaction effect between type of message framing and social value orientation. Positive message framing showed a higher effect than negative message in the case of proself. However, there was no difference in message framing effect when there was high personal relevance and prosocial. Lastly, the implications of this study was presented. First, this study expanded the scope of research related to message framing. Second, the use of moderating variables such as personal relevance and social value orientation increased the possibility of practical application. In addition, limitation and further study directions was discussed.

  • Purpose - In the present study, it has become the most important necessity in our daily lives that consumers' psychological factors affect the use of smartphones, and it has been analyzed through behavioral economic approaches. In this respect, the present study is intended to apply the heuristic theory and the prospect theory among behavioral economics theories to examine how psychological factors affect consumers' product selection. Research design, data, and methodology - In the present study, using smartphone repurchase as a dependent variable, whether regulatory focus effects have interaction effects on behavioral economic theories and behavioral economic effects such as possession (ownership) effects, framing effects, and brand recollection. As an analysis method, questionnaire surveys conducted with university students in Incheon were examined through Two-Way ANOVAs using the SPSS23 package. Results - The analysis from the results are as follows. Using smartphone repurchase as a dependent variable, the main effects and interaction effects on two variables; satisfaction difference with product functions and positive framing variable were statistically significant. Using repurchase as a dependent variable was statistically significant, there was no interaction effect between the two variables; satisfaction difference with product functions and the difference of brands in possession. Using smartphone repurchase as a dependent variable, interaction effects on two variables; satisfaction difference with product functions and the lengths of product possession periods were not statistically significant. The results from the analyses of interaction effects of brand recollection and brands type were statistically significant in possession using repurchase as a dependent variable. The results from the analyses of the main effect of the brands type were statistically significant in possession using repurchase as a dependent variable. Conclusions - The implication of the present study is that it suggests the factors that became important for customers' smartphone purchase following the change in the meaning of smartphones from practical products in the past to hedonic products. Limitations of the present study are first, the study subjects are limited to students and the number of copies in questionnaires is only approximately 130, which is insufficient, so that the present study is not sufficient as a study for entire smartphone users.

  • This study aims to examine the effects of message framing of restaurant menus on customers' perceptions (trust and immersion) and their willingness to pay a premium price. The contents of messages focused on a hypothetical restaurant's cause-marketing activity. Four types of message framing were created: The first two types were varied by the presence and absence of the information about the current cause-marketing outcome, and the second two types were varied by positive and negative framing. The results showed that respondents in general had trust in cause-marketing messages and immersion of cause-marketing message by negative framing lead to positive influence of willingness to pay. Furthermore it had a significant effect on willingness to pay depending on cause-marketing message type and negative message framed messages showed an intention to willingness to pay a premium price. This study compared the difference in messages by type as an extension of the studies of cause-marketing messages in the past. The results of this study will be used for establishing effective marketing strategies for today's foodservice companies and serve as objective data for setting differentiated prices under the circumstance where the importance of companies' social responsibilities is growing.

  • This study aimed to investigate the differential effects of self-relevance on framing effects. For this purpose, the participants were allocated into two frame type conditions(positive vs. negative), and asked to respond on six decision-making scenarios manipulated by self-relevance levels(low vs. high). The results can be summarized as followings. First, although self-relevance level made no significant difference in framing effects, the positive frame condition tended to induce larger framing effects than the negative frame condition. Second, no significant interaction effect between frame type and self-relevance level condition was found in the positive condition, whereas high self-relevance level condition induced smaller framing effects than law self-relevance level condition in the negative frame condition. These results indicated that although self-relevance tended to reduce framing effects, this effect can be differed in frame types.

  • This study aimed to investigate the differential effects of individual's cultural disposition (individualism-collectivism or horizontal-vertical thinking) and need for cognitive closure(NFC) on framing effects. For this purpose, the participants were divided into 4 different cultural disposition groups based on Singelis et al.'s[1] INDCOL scale, and 2 different NFC groups based on Lee's[2] NFC Scale, and then asked to respond on 5 decision making scenarios. The results can be summarized as followings. First, participants preferred risk-avoidant option in gain frame, whereas risk-seeking option in loss frame. Second, there are no difference of cultural disposition on framing effects, but high NFC group showed larger framing effects than low NFC group in loss frame. Third, collectivism and vertical thinking in high NFC condition showed larger framing effects than low NFC condition.

  • Messages to help people far away, such as International relief campaign, are heavily influenced by situational factors. In this light, the study examined whether the message characteristics (gain/loss framing) and the individual characteristics (previous attitude to helping activity) interact to affect the message attitude and behavioral intention. The study was conducted by an experiment involving 220 subjects. The analysis resulted in the significant interactions between gain/loss framing and pre-attitude by the same direction for message attitudes and behavioral intention. It was shown that gain framing worked more effectively for the relatively more friendly group towards helping activities than for the less friendly one. The same direction was shown in the loss framing, but its difference was smaller. The process of the interactions appeared as mediated by anticipated satisfaction. The practical and theoretical implications were discussed for proper planning of messages to help others.

  • This paper will discuss three different ways of framing relationships between identity and built forms mainly through the theoretical frame works of David Harvey, Christine M. Boyer, Jane M. Jacobs, Doreen Massey, Paul Rabinow, and Michel Foucault. From these scholars, this paper will argue the relationships between identity and built forms are categorized as such: "Becoming", "Politics of Difference", and "Construction of Self". Besides these three approaches of framing identity and built forms, relevant ideas will be drawn from the work of other scholars in so far as their theoretical positions relate and support these three key frameworks. To approach the critical points of each debate, these three categories are further analyzed by juxtaposing the epistemological positions between them. Through the comparisons, this paper illustrates the interrelationships and interdependence of these three categories whose discursive power gains rapid popularity in Western scholarships. By incorporating the three ways to view the relationship between built form and the identity of social groups, drawn is a suggestion for a broader imagining of new spatial identity.
