This study mainly focused on measuring the impact of comments for a particular song on the number of streamings and downloads. We modeled multiple regression equations to perform this analysis. We chose digital music market for the object of analysis because of its inherent characteristics, such as experience goods, high bandwagon effect, and so on. We carefully utilized text mining technique in accordance with the algorithm of Naïve Bayes classifier to distinguish whether a comment for a piece of music be regarded as positive or negative. In addition, we used 'size of agency' and 'existence of hit song' as moderating variables. The reason for usage of those variables is that those are assumed to affect users' decision for selecting particular song especially when downloading or streaming via music sites. We found empirical evidences that positive comments for a particular song increase the number of both downloads and streamings. However, positive comments may decrease the number of downloads when the size of agency of the artist is big. As a result, we were able to say that a positive comment for a particular song functioned as 'word-of-mouth' effect, inducing other users' behavioral response. We also found that other features of an artist such as size of the agency that the artist belongs to functioned as an external factor along with feature of the song itself.

Technology has had a tremendous impact on our daily lives. Recently, technology and its impact on aging has become an expanding field of inquiry. A major reason for this interest is that the use of technology can help older people who experience deteriorating health to live independently. In this paper we give a brief review of the in-home monitoring technologies for the elderly. In the pilot study, we analyze the possibility of employing the data generated by a continuous, unobtrusive nursing home monitoring system for predicting elevated(abnormal)pulse pressure(PP) in elderly(PP=systolic blood pressure-diastolic blood pressure). Our sensor data capture external information(behavioral) about the resident that is subsequently reflected in the predicted PP. By continuously predicting the possibility of elevated pulse pressure we may alert the nursing staff when some predefined threshold is exceeded. This approach may provide additional blood pressure monitoring for the elderly persons susceptible to blood pressure variations during the time between two nursing visits. We conducted a retrospective pilot study on two residents of the TigerPlace aging in place facility with age over 70, that had blood pressure measured between 100 and 300 times during a period of two years. The pilot study suggested that abnormal pulse pressure can be reasonably well estimated (an area under ROC curve of about 0.75) using apartment bed and motion sensors.

Purpose : In the aviation industry, we will investigate the impact of users' acceptance of technology on their usage behavior and find out the factors that affect their acceptance of technology. We will expand the prior study to find out the impact of the self-service technology of Incheon Airport. Research design, data and methodology : Within the last six months, the survey was conducted on people using self-service technology at Incheon International Airport from July to August 2019. Part 307 of the valid questionnaires were used for this final analysis. The collected data were used to perform frequency, factor, reliability, and multiple regression analyses using the SPSS statistical package. Results : Individual aspects of external variables, service aspects and system aspects have been shown to affect usefulness and perceived ease of use. Also, perceived ease-of-use and usefulness have effects on users' intention to accept technology. Conclusions : The perceived easement and perceived usefulness of Incheon International Airport has been shown to affect self-service users. Increasing the user's self-efficiency and increasing the user's expectations for benefits, convenience, rapid processing, and minimal effort will have a positive meaningful effect on the intention of accepting the technology.

The franchise system has become more widely adopted by Korean distribution industries than before as foreign direct investment is liberalized in these industries. However, a number of problems has arisen between franchisers and franchisees recently. In this regard, the objective of this study is to identify problems arisen between franchisers and franchisees of convenience store operation. More specifically, this paper investigates how credibility between two parties is affected by the internal political structures, including bureaucratic structure and relational norms, and impact strategies of franchisers. The results of this study can be summarized as follows : Under rapidly changing channel environment, credibility between franchisers and franchisees tend to be characterized as the bureaucratic structure rather than relational norms. This result suggests that franchisees are more likely to recognize the power of franchisers in Korean convenience stores. This paper also shows that the adoption of coercive impact strategies decreases credibility and vice versa. The results of this paper suggest following implications. In order to have mutually beneficial relationship franchisers and franchisees have to share benefits and costs incurred by their convenience store operation, and to raise their ability to revise contract terms to accommodate changes in external environments. It is also important for the development of convenience store operation to construct more efficient relationship between franchisers and franchisees by adopting supportive norms rather than opportunistic ones.

Purpose: The purpose of this paper is to find out the impact of financial leverage on firm's profitability in the listed textile sector of Bangladesh. Research design, data and methodology: A sample of 22 DSE listed textile firms has been used to conduct the study. In this study, firm profitability is measured by Return on Equity (ROE) and both short term debt and long term debt are used as the as proxies of financial leverage. Pooled Ordinary Least Squares (OLS), Fixed Effect (FE), and Generalized Method of Moments (GMM) models have been used to test the relationship between financial leverage and profitability of firms. Result: This study finds a significant negative relationship between leverage and firm's profitability using the Pooled OLS method. The result is also consistent with the fixed effect and GMM method. This result implies that firm's profitability is negatively affected by the firm's capital structure. Conclusion: The study concludes that maximum textile firms use external debt as a source of finance as they don't have sufficient internally generated funds. This study recommends that firm should give more emphasize on generating fund internally to meet up their financing needs.

This research examined an immediate loading capable of providing a masticatory function and financial affordability while satisfying every requirement of a useful immediate loading. In this research, numerical value analysis was performed on couple-type posterior teeth implants developed by making up for the problems of extant implants. As a result of examining the effects of external impacts on extant implants and their deformation, relatively lager deformations separated from a molar were found concerning molar deformation implant with the maximum deformation level being approximately 1.657mm. In this research, the improved implant showed much improvement in terms of impact analysis in its deformation dispersion status after unloading the impulsive load from a punch. As for the case of hepf, about 1.657mm occurred but the improved model showed about 0.9217mm, exhibiting 55.6% advancement.
