  • The causes of noise generation according to the classification of indoor spaces are very diverse. Individual happiness is infringed by this noise. In this paper, We tried to visualize the spatial sound characteristics of public places using sound color to express them so that anyone can sympathize. The noise inside a conference room of a medical device company was measured for 100 minutes, and the frequency band was divided into three different types of existing sound pressure expression units. Because the size of the noise is expressed differently depending on the situation, There are cases where there is a difference of opinion between the measurer and the researcher. This noise measurement experiment was conducted, and the sound color was applied to classify it on a log scale considering auditory characteristics. As a result of comparing this with the result expression for different loudness expression units, A specific table in different units yielded almost similar results. In addition, the sound source section for 100 minutes was divided into three analysis sections, the analysis sections were different, and the size of the energy ratio for each analysis section was divided in the form of an envelope. The characteristics of the low-frequency region of the space have a high energy ratio, and the decrease in the energy ratio according to the increase in frequency is constant and regular. You can see that conversations are possible.

  • Purpose - The present study aimed to investigate the difference between entity theorists and incremental theorists in the extent of attributing efforts and traits of consumers for the realization of pursued goals. Furthermore, the present study was conducted to determine the difference depending on circumstances. In this regard, the circumstances where consumers felt pride were divided into those in which important goals and ordinary life goals were achieved. Research design, data, and methodology - An empirical study was performed, which was divided into group 1 and 2. Group 1 is the experimental group concerned with the important goal achievement, and group 2 is the control group related to daily ordinary goal achievement. 80 college students were assigned to each group, respectively. The empirical study for each of the two groups was performed respectively by means of questionnaire survey. In the experimental group, t-test was used to verify the hypotheses for the empirical study. In the circumstances of the control group, t-test was also used to examine whether the results were same as those shown from the analysis of experimental group data or not. Results - According to the group 1 and 2, the t-test of the empirical study showed that entity theorists tended to attribute the achievements of goals to their traits more than incremental theorists did, whereas the incremental theorists tended to attribute achievements of goals to their efforts more than entity theorists did in the important goals-achieved circumstance. In the circumstance of daily life goals-achieved, additional questionnaire survey and analysis were conducted, however, there was no difference between incremental and entity theorists in regard to attributing realization of goals to their efforts, and it leads to assess the difference in the meaning of invested efforts between important goal and ordinary goal achievement. Conclusions - Considering that the feeling of consumers has been regarded as one of the significant factors in marketing mix management, the results of this study are considered as significant implications for management. The implications can be said that when incremental consumers feel authentic pride in the important goals-achieved circumstance, marketers are requested to emphasize the fact that the efforts of consumers have contributed to realization of the important goals. By contrast, when consumers feel hubristic pride in both circumstances, marketers are requested to approach to entity-oriented consumers by way of trait. Authentic and hubristic pride are pervasive and engendered by important events or daily routines, and they could have effect on delaying making decisions. Therefore, it is necessary for future research to examine the unexplored difference of effect between incidental authentic and hubristic pride on consumer's self-control. In particular, future researches are related to the extent of difference in attributing efforts and traits. The consumers'realization for the previously pursued goals between entity theorists and incremental theorists affects their present or long distant decisions in self-control dilemmas. The consumers are faced with choosing one between virtuous long term- related option and vice immediate option.

  • In this paper, we propose a new fast algorithm for effective scene change detection. The proposed algorithm exploits Otsu threshold matching technique, which was proposed earlier. In this method, the current and the reference frames are divided into square blocks of particular size. After doing so, the pixel histogram of each block is generated. According to Otsu method, every histogram distribution is assumed to be bimodal, i.e. pixel distribution can be divided into two groups, based on within-group variance value. The pixel value that minimizes the within-group variance is said to be Otsu threshold. After Otsu threshold is found, the same procedure is performed at the reference frame. If the difference between Otsu threshold of a block in the current frame and co-located block in the reference frame is larger than predefined threshold, then a scene change between those two blocks is detected.

  • The purpose of this study was to compare dietary culture consciousness of rural and urban housewives through a nationwide survey. Interviewers interviewed 500 housewives(250 in rural and 250 in urban) using closed-ended questions. The dietary culture consciousness was divided into two parts of traditional aspect (dietary habit and ritual diet) and desirable aspect (food choice and nutrition knowledge). Each domain consisted of six items. Results of the study are summarized as fellows : 1) As a whole, dietary culture consciousness of rural housewives was more traditional than that of urban housewives in traditional aspect, and there was no difference of consciousness between rural and urban housewives in desirable aspect. 2) There was significant difference at 1% level between two groups in traditional aspect and there was no difference in desirable aspect. 3) By the analysis of each item, there was significant difference between two groups in 14 items. Especially, the item of westernized breakfast pattern was more acceptable in urban housewives than in rural. 4) In relationship between socio-demographic characteristics of housewives and dietary consciousness of them, age, educational level and religion of housewife were significant in traditional aspect, and so were educational level and job experience of housewives in desirable aspect. Dietary consciousness of rural housewives' was influenced by job experience (in traditional aspect) and age of housewives and level of living (in desirable aspect) In the case of urban housewives, level of living was significant in traditional aspect.

  • Purpose: This study examined whether 1) the motor inhibition response as cognitive-behavioral component is learning though a stop signal task using stop-signal paradigm, and 2) whether there is a difference in the learning degree according to imagery training and actual practice training. Methods: Twenty young adults (males: 9, females: 11) volunteered to participate in this study, and were divided randomly into motor imagery training (IT, n=10) and practice training (PT, n=10) groups. The PT group performed an actual practice stop-signal task, while the IT group performed imagery training, which showed a stop-signal task on a monitor of a personal computer. The non-signal reaction time and stop-signal reaction time of both groups were assessed during the stop-signal task. Results: In the non-signal reaction time, there were no significant intra-group and inter-group differences between pre- and post-intervention in both groups (p>0.05). The stop-signal reaction time showed a significant difference in the PT group in the intra-group analysis (p<0.05). On the other hand, there was no significant intra-group difference in the IT group and inter-group difference between pre- and post-intervention (p>0.05). Conclusion: These results showed that the motor inhibition response could be learned through a stop-signal task. Moreover, these findings suggest that actual practice is a more effective method for learning the motor inhibition response.
