  • Presently, there is the dilemma of uncertainty with respect to the evaluation of sound and vibration based on the fact that there is obviously no agreement upon appropriate methods to measure the "truth" concerning the acceptance of sound and vibration. To evaluate properly physical and perception data in sound and vibration it is necessary to implement new methods and innovative approaches to understand the input of human response in sound design. Fortunately, an elaborate dialogue of the usefulness and applicability of those approaches is in progress. Moreover, the need of using and combining perception and physical data in order to comprehend the process of human perception and evaluation sufficiently is widely accepted. However, still the question remains how the goal of an adequate combination can be achieved. Clearly, themultidimensional human perception cannot be easily reduced to singular numbers. Moreover, factors, among others the meaning of the sound, the composition of the diverse sound sources, the listener's attitude, expectations and experiences, are significant parameters which have to be considered to comprehend the different perceptions and evaluations with regard to specific stimuli. Taking under consideration the physical, psychological, and cognitive dimensions as well as the integration of aspects of design require partially various new approaches. While binaural measurement and analysis technologies and psycho-acoustics are well established as they are proved to be valuable auxiliary tools; it has not been achieved to develop generally acceptable measurement units concerning sound quality. Consequently, there is a need for new approaches and methods which make it possible to comprehend sufficiently the process of perception and evaluation. Going with people's mind will be one solution for the future; thisconcept will be introduced based on the development in sound design.

  • This research was intended to investigate how risk perception and risk reduction behavior by consumers differ according to different product characteristics of clothing. The responses of 318 female college students living in Seoul and surrounding vicinities were collected and analyzed. Inner wear, blue-jean pants, coat were selected as representing each clothing product characteristics. Frequencies distribution, regression and correlation coefficient were utilized for statistical analysis. Results are as follows. 1. The type of perceived risk and risk reduction behavior differed according to product characteristics of clothing. Physical and performance risk were more highly perceived for the purchase of innerwear. However, for the purchase of jean pants and coat, socio-psycho-logical and economic risk were also perceived highly because the rate of fashion change, social symbolism, and coordination with other clothing items become more important characteristics. To reduce perceived risk, dependency on past purchase experiences and shop-ping were mostly preferred method regardless of product characteristics of clothing. 2. Risk type as determinant variables for predicting overall risk differed according to product characteristics of clothing. But fashionability and usefulness were common determinant risk variables, which identifies typical characteristics of clothing product.

  • On the basis of the concept retained in nutition label(NL) the consumer's perception use and demand on NL nutrition knowledge(NH) purchase of nutrient controlled food and dietary modification for health were examined. The subjects were 1203 house wives mainly in the age of 30-40 and self administered questionnaire was employed. The results were as follows. Subjects' demand on nutrition information was greater while the availablity and usefulness of NL was unsatisfactory. The purchase frequencies of nutrient controlled foods were higher compared to NL reading. The use comprehenison reliability of nutrition information were better in high NK group compared to low NK group except the reliability on health claims. The required nutrients for content information were in the order of calorie Ca cholesterol Fe protein and total fat. The demand for nutrient content information was carrelated with intention of subjects' dietary modification but not the use of NL. These results indicate that NL be a good source of nutrition information and the consumers' demand for NL was based on their dietary purpose though the use of NL was unconfirmed.

  • This study aims to examine agricultural college students' perception of readiness and barriers towards implementation of ICT program. Data were gathered from 175 student of agricultural college in Korea. Descriptive statistics, exploratory and confirmatory factor analysis, t-test, and one-way ANOVA were applied to analyze the data. Results reveal that technology usefulness perception scores were high among the readiness components, but students readiness and school infrastructure readiness were low. Results also shows that policy and technology factors were also seen as the main barriers of ICT program implementation. Findings show that demographic variables did not significantly affect readiness and obstacles. The results of this study can provide guidance to the government or agricultural college organizations when considering readiness and barriers towards implementing ICT programs. In addition, this study contributes to improve the theory of adoption behavior and contributes to the foundation for future research aimed at improving our understanding of agricultural college students' behavior.

  • Organizations have attempted to develop Knowledge Management Systems for achieving competitive advantage by effectively managing organizational knowledge. However, if Knowledge Management Systems are not user-oriented, organizations may not attain desired goals. That is, it must be utilized and accepted by organizational members to be successful systems. This study proposes an extended Technology Acceptance Model and empirically validates it. For that purpose, a research model is set UP that consists of antecedent variables, perception moderators, and intention to use the system. Empirical data analysis found significant relationships among research variables, as suggested in research hypotheses. The results of the analysis indicated that perceived usefulness, ease of use, job relevance and information quality should be considered as important factors in designing Knowledge Management Systems. In addition, perceived value, incentive, affect, self-efficacy, and image were found to influence the perception of users in the usage situation.

  • In the era of globalization firms must operate all useable resources into marketing activities to survive on the unlimited competition. However, firms face many kinds of disputes with counterparts because of aggressive marketing activities. There are two ways of solving these disputes : litigation and arbitration. As compared to litigation, arbitration is more popular because of such merits as the enforcement of arbitral award in foreign countries, the single trial system, the settlement by specialists, and the confidential proceedings. This paper examines trade firms' perception on the arbitration system and the effects of the advantages of arbitration and quality of arbitrators on the outcome of arbitration. The results show that the advantages of arbitration and quality of arbitrators influenced positively on the outcome of arbitration, but influenced negatively on the closed-door of arbitration procedures and a fair procedure of arbitrator. Though this paper has several limitations, this paper may contribute to figure out the relationship between arbitration merits and quality of arbitrator and outcomes as a first empirical paper and to suggest future research method and direction.

  • The purpose of this study is to develop a Technology Acceptance Model (TAM), to determine differences in gender perceptions in adopting non-cash transactions. In this study, the authors provide a measurement of differences in gender perceptions in adopting cashless, which refers to perceived usefulness, perceived ease-of-use, and perceived security. Respondents in this study were students from the millennial generation who are very familiar with the use of technology, especially non-cash transactions. The data collection technique used in this study was a survey, by distributing questionnaires to 260 respondents. The data were processed statistically through Structural Equation Modeling (SEM). The results of this study indicate that for men, ease-of-use of transactions does not increase the use of non-cash transactions. Meanwhile, for women, perceived ease-of-use has a significant and positive effect on the use of non-cash transactions. Furthermore, perceptions of usability and security have a positive and significant impact on using non-cash transactions. It was also found that female students had a positive, but not significant, effect on the use of non-cash transactions. This means that there has been a difference in the perception of gender, between men and women, in responding to the use of non-cash transactions.

  • Before COVID-19 outbreak in 2019, it is the core value of airline's service to provide check-in service to passengers face to face. However, due to the global pandemic of COVID-19 outbreak, it is expected the airline service in the future would be dramatically changed from being contacted to being untacted with technology-based self service(TBSS). This paper analyzed the perception of passengers using self service technology and their acceptance. According to empirical analysis, it was found that the change of passengers' perception after COVID-19 has a significant positive effect on the innovation of TBSS. The innovation of TBSS(Effectiveness and certainty) had both significant positive effect on the passengers' acceptance on TBSS at airport. Among variables of TBSS, convenience rather than usefulness of TBSS had a significant positive effect on intention to use TBSS of passengers. It was proposed that airlines not only contribute to increase acceptance of TBSS but also inform and promote the prevention effect of TBSS and the importance of untact service to minimize congestion at check-in counter in airport.
