Focusing on the emerging influencer market of SNS (Social Network Service), This study attempts to clarify the priority of Influencer characteristics when the customer decided to purchase products through the promotion of influencers. Since the influencer marketing differs from the Online information source marketing, this study has an academic implication in that integrated the influence of the characteristics of the Online information sources and the characteristics of SNS contents. For this purpose, through the literature research on Information sources and Influencers, the characteristics of influencers were reconstructed and priorities were derived using the AHP (Analytic Hierarchy Process) technique. The upper layer of the AHP structure was set to expertise, trustworthiness, social attractiveness, and content attractiveness, and the lower layer structured the model with 13 subfactors. The results are summarized as follows. First, in the result of combining the importance of the $1^{st}$ and $2^{nd}$ classes, the detailed factors of expertise and trustworthiness, ranked from the top to six, are largely influenced in purchasing decisions in influencer marketing. Second, content attractiveness is the third rank in the $1^{st}$ layer. Influencer marketing shows that content is more important than social attractiveness. Besides, the $7^{th}$ to $9^{th}$ positions of the overall rankings accounted for visual information, storytelling, and external attractiveness, which are the details of content attractiveness, and it is confirmed that it is more effective for influencer marketing to emphasize content attractiveness than social attractiveness. Although the influencer marketing differs from the existing information marketing, this study has an academic implication in that integrated the influence of the characteristics of the source and the characteristics of the contents.

The acoustical sources of intake and exhaust systems in fluid machines are often characterized by the source impedance and strength using linear frequency-domain modeling. In the case of the sources which are nonlinear and time-variant, however, the source parameters were sometimes incorrectly obtained. In this paper, the source model and direct measurement technique are modified in order to evaluate the effect due to nonlinear and periodically time-varying source character as well as the linear property of the reflectivity of in-duct fluid machine source. With a priori known kinematical information of the source, the types of nonlinear time-variant terms can be presumed by a simple physical model, in which there is practically no restriction on the form of the model. The concept of source impedance can be extendable by introducing the linear frequency response function for each nonlinear or time-variant input. Extending the conventional method and adapting the reverse MISO technique, it is possible to develop a direct method that can deal with the nonlinear time-variant source parameters. The proposed direct method has a novel feature that there is no restriction on the probability or spectral natures of the excited sound pressure data. The present method is verified by the simulated measurements for simplified fluid machines. It is thought that the proposed method would be useful in predicting the insertion loss or the radiated sound level from intake or exhaust systems.

Interest in and use of social media as a communication channel are consistently evolving; in addition therefore, corporate social responsibility (CSR) activities have been often conducted on online channels such as social media due to the advantages offered by the rapid spread of information. Consumers can be persuaded differently and their cognition can be influenced depending on who delivers what message. This study examines the influence of information source characteristics on eWOM acceptance of CSR messages and attitudes toward a company. This study compares cases: when a company sends their CSR message versus when an individual (i.e., consumer's acquaintance) sends the company's CSR message. A total of 320 respondents were presented with online stimuli and responded to the questionnaire to identify this phenomenon. Vegan fashion (which refers to products made from raw materials without animal cruelty) was used as stimuli in this study because it is a representative example of CSR activities. As a result, when consumers are exposed to CSR messages online, perceived expertise, trustworthiness and attractiveness of information source affect consumer's electronic word-of-mouth (eWOM) acceptance and attitude toward a company. However, only trustworthiness influences eWOM acceptance in cases of a corporation information source. This study confirms the differences in eWOM acceptance and in attitudes to the company depending on to whom the messages were sent and with what content.

The internet is one of the modern facilities that has been diffused very rapidly in recent years and tremendously influenced on our life. Although the adolescents are major users of internet, the literature in clothing and textile area has not addressed the relationships between adolescents' internet use and clothing behavior, The purpose of this study was to examine the differences of adolescents clothing behavior. purchase evaluative criteria, and information source according to the use of internet. Descriptive statistics, t test, Analysis of Variance (ANOVA), and Duncan test were employed to analyze the data collected from the convenience sample of 572 middle and high school students in Gyeongnam, Korea. The use of internet was partially related to the adolescents' clothing behaviors. purchase evaluative criteria. and information source. Also, it was observed that the frequency and purpose of fashion website tended to be related more than the amount and purpose of internet did. Marketing implications from the results were suggested.

Historically, mothers have been noted as active health information seekers, reflecting their roles as health mangers and caregivers for their family members. However, previous studies have focused on health-related information behavior among mothers in native populations or mothers of children with specific diagnoses. To fill this research gap, this study focused on health information behavior among mothers of healthy infants and toddlers. Using Wilson's (1997) information-seeking model, this study aimed to uncover the relationships between mothers' demographic characteristics and their health information source use. Online surveys were completed by 851 mothers: 255 U.S.-born mothers, 296 Korean-born mothers, and 300 Korean immigrant mothers living in the United States. Results indicated that there were statistically significant relationships between mothers' nine demographic characteristics (mother's age, education level, household income, employment status, the number of children, years living in the U.S. (or Korea), fluency in speaking English, size of household, housing status) and their health information source use. Based on the results, the implications for information professionals at diverse organizations are discussed when they provide health information services to this specific population.

Sound intensity techniques and ODS(Operational Deflection Shape) techniques are applied to identify the acoustic noise source of a hard disk drive and its control system. The sound intensity is used to visualize the noise source locations, and the ODS information to visualize the vibration pattern and to obtain the dynamic characteristics of the noise sources. The measurement systems are customized to accurately measure the sound intensity and ODS distributions of HDD system in space domains as well as frequency domains. The measurement systems for the sound absorption and transmission loss of materials are also used to support the background data for the efficient noise control. Using the visual information of source locations and its dynamic characteristics, the partial noise barrier structure and optimum absorption are designed and its controlled sound power level is proved to be under 3.1 Bel(Idle)/3.3Bel (Seek) which is the lowest level in the disk drive industry.

This study confirmed the types of shopping information sources during travel abroad, and developed a profile of tourists in terms of demographics, travel, and shopping behavior. Shopping information sources and characteristics of shopping products were identified first. Thereafter, travelers were segmented by their information-seeking behavior. An online survey method was used to get data from Korean vacationers in their 20s-50s, while factor analysis, cluster analysis, ${\chi}^2$ test and ANOVA were applied to analyze data. The results were as follows. First, the shopping information sources of overseas tourists were composed of four factors including sources from travel agents/media, information from travel books and local sources, and word-of-mouth sources. Also, four factors in product types and four product attributes were identified. Second, tourists were clustered into two groups, active and passive shopping information seekers, based on shopping source behavior. Third, two groups differed in terms of demographics, showing an older age and higher income for active shopping source seekers. Active shopping information users tended to join package trips with family members, and they were more satisfied with the trip. With regard to shopping, active shopping source seekers spent more money for shopping and preferred all kinds of shopping goods with an emphasis on travel shopping. In conclusion, shopping information sources seemed to be a meaningful tool for segmenting tourists. Rich, older, family tourists would be an major target market for local retailers.
