The development of contaminated sites often requires foundation concrete to be placed in contact with soils contaminated with organic compounds. There is a common perception that organic compounds affect the setting and hardening of concrete, giving a reduced long-term strength. In this study, unconfined compressive strength tests for concrete cured in Ethylbenzene were performed. The possibility of byproduct to be used for aggregate of concretes as materials of construction was also evaluated by carring out the investigation of the characteristics of the mixture of concrete and crushed oyster shell which is treated as waste material and often illegally disposed at coastal oyster production site. The transformation of strength characteristics was investigated by varying the blending ratio of fly ash.

The purpose of this research is to explore the relationship between organizational cultural perception gap and organizational effectiveness. it has rarely been studied in the academia. The research of the organizational cultural perception gap provides entrepreneurs directions on how to manage a company. Since previous studies have been focused on cultural type or strength, this study aims to suggest managerial implication in detail by analyzing present-ideal gap. Furthermore, this study would discover how it is different according to a psychological mechanism. The empirical results of 134 employees showed that the organizational cultural perception gap (i.e. Clan) had a negative effect on job satisfaction and affective commitment. In order to reduce the negative effects of organizational cultural perception gap, it is necessary to reach an agreement with members on organizational culture, which is ideal for organizational level, and understanding the members' internal motivations is important for proper organizational management.

This study attempted to grasp the status and perception of Uljin Geumgangsong by grasping mass media issues and user perception using big data, and to present basic data when constructing monitoring using user perception by examining the establishment relationship of agenda setting from a time-series perspective. The results of collecting and analyzing text data that can identify mass media and visitor awareness are as follows. First, both mass media and visitor keywords were related to the importance of the value and meaning of Uljin Geumgangsong. Second, in the case of the connection network, Geumgang Pine Agriculture was centered, but in the case of difference in perception between mass media and visitors, such results were derived due to the object of interest. Third, in the case of the connection relationship structure, the connection strength was strong because there were many overlapping contents of mass media. Fourth, as a result of the centrality analysis, both mass media and visitor-aware keywords were positively recognized as spaces created and maintained through institutional support, and objective perception could be grasped by finding hidden keywords. Fifth, as a result of time series analysis, it was possible to grasp the flow through the issue keywords that appeared by period, and unlike the past, it was recognized as a place for tourism and travel. Finally, as a result of examining whether the agenda setting is consistent, there is a mass media influence, so it is thought that more diverse and more information and publicity are needed by utilizing it.

This study was conducted to explore pending issues as an obstacle factor in the library growth and progress through measurement of Korean and Chinese College undergraduates' perception on the library, and suggest its countermeasure to that the study result showed that their perception to the library's social and cultural function was low, so the library's cultural events need to be consolidated to enhance perception, and the Korean student's study zeal was lower than Chinese, and amny students did not go to the library, but an incentive is needed to escalate the strength of course study or the library availability. Also a countermeasure should be established such as a class link project through continuing specialized librarians' training strengthened, users' group education for the satisfaction enhancement and validity of the information service users.

This research tries to examine the effect of brand experience in service marketing perspective for generalized application. The analysis was held with customers who recently visited in retail stores by using SPSS18K and Smart PLS 2.0. The study verified the structural equation model hypothesizing the relationship among brand experience, relationship quality, and relationship strength. According to the result of this study, four brand experience factors have positive effect on the relationship quality. In detail, the effect of sensory experience was strongest. Furthermore, the effect of relationship quality on relationship strength also significant as prior researches addressed. The research has several marketing implication on brand experience management and customer relationship management. For service firms, customers' perception of positive brand experience can generate the tangible and intangible performance in the relationship marketing perspectives.

This paper presents the HRTF based experimental approach to figure out why the human auditory perception on the interior noise source including the directional tonal components does not well match with the dominant features extracted from recorded acoustic signals in terms of psycho-acoustics. Since the general objective evaluation models for tonalness among various sound attributes are a function of width, frequency, excessive level of tonal components respectively, the directional tonal components cannot be properly evaluated without considering the effects of head-related transfer function on the binaural auditory perception. Thus, the directivity of source is additionally considered to prevent the erroneous conclusions from the same sound source in the process of source identification. The signal synthesis technique is used to solve a little difficulty in measuring all of desired acoustic signals for jury evaluation. The sound attributes of synthetic acoustics signals are analyzed to roughly predict the results of jury evaluation in advance by using sound quality factors such as loudness, sharpness, roughness, fluctuation strength and tonality. The jury evaluation is carefully conducted based on the recommended guideline suggested by N. Ottoet al. Each sound is respectively evaluated by selecting a value between -2 and 2 in intervals of 0.2 point. Through above procedure, based on the results of jury evaluation, it is confirmed that serious problems can be caused in the process of analyzing the dominant sound attributes in terms of psycho-acoustics according to the type of a microphone and a playback system.

Background: Increasing age and loss of teeth weaken oral muscle strength. This study aimed to investigate the positive effects of orofacial myofunctional training on elderly people. Methods: Thirty six elderly individuals in a welfare center and a senior citizen center were included in this study. A survey regarding lip and tongue strength suvsequent to orofacial myofunctional training and oral health-related quality of life was conducted from April to June, 2019. Data were analyzed using PASW statistics ver. 18.0. Results: The experimental group, showed an increase in lip strength (from 9.79 to 10.31) and tongue strength (from 41.26 to 43.97) after orofacial myofunctional training. The perception of oral health-relatedquality of life was enhanced (from 2.26 to 2.07). In particular, the frequency of dry cough for food removal while swallowing decresed due to an incresed in the secretion of saliva (p<0.05). Correlation analysis showed that the number of functional teeth was positively related to oral health-related quality of life. Conclusion: Orofacial myofunctional training for improving lip and tongue strength is effective in the elderly. In older societies, oral strength should be maintained to improve oral health-related quality of life. It also suggests the interest of oral health workers and applying orofacial myofunctional training programs.

Pitch is a perception related to frequency, one of the psychological aspects or attributes of tones, and an important factor to determine sound quality of sound together with loudness and timber. while a study on pitch has been actively achieved In the part of speech recognition and speech separation, that for analysis and improvement of product sound quality is not yet enough.
