Purpose: The objective of this study is to deepen our understanding of the key factors that determine sustainability in terms of suppliers based on the transactions between suppliers (pharmaceutical companies) and buyers (medical institutions) in the pharmaceutical distribution industry. Research design, data and methodology: Transaction justice factors were derived from three main components: distributive, procedural and interpersonal, five hypotheses were set up. The respondents from the data collected through an online survey are sales staff of pharmaceutical companies. Total of 319 questionnaires are collected and used to verify the hypotheses through the SPSS 22.0 and AMOS 22.0 programs. Results: Justice of transactions perceived by the salesperson of pharmaceutical companies was found to have a significant effect on the relationship commitment. Among them, procedural justice was found to have greatest relative influences. In addition, relationship commitment was found to have a significant effect on sustainability performance. Thus, all hypotheses were adopted. Conclusions: The results of this study, can be used as basic data for the guidelines for fair trade between pharmaceutical companies and medical institutions. In addition, it is expected that the study will have significance in that it examined sustainability through transactions with buyers from the viewpoint of suppliers.

While there are lots of studies on examining the effects of social rapport in many research areas, however, there is a little work in examining the effect of the social rapport in social network service (SNS) contexts. Thus, this study attempts to examine the effect of social rapport in SNS settings. To address the research questions, this study has presented its hypotheses and conducted three experimental approaches by collecting 180 data from student subjects who have prior experiences on using SNSs to verify the hypotheses. This study has examined three experiments the effects of characteristics of Facebook(i.e. the number of mutual friends, the number of post likes, and the post personalities) on the social rapport and user responses. This study has conducted two-way ANOVA to verity its proposed research hypotheses. Based on three experiments, this study found that both the effects of the number of post likes and the number of post likes on the social rapport were not significant. Based upon empirical findings, this study has demonstrated how the effects of social rapports in SNSs were different from those of previous studies, and brought more attentions to the relevant literature.

A musical sheet is read by optical music recognition (OMR) systems that automatically recognize and reconstruct the read data to convert them into a machine-readable format such as XML so that the music can be played. This process, however, is very challenging due to the large variety of musical styles, symbol notation, and other distortions. In this paper, we present a model for the recognition of musical symbols through the use of a mobile application, whereby a camera is used to capture the input image; therefore, additional difficulties arise due to variations of the illumination and distortions. For our proposed model, we first generate a line adjacency graph (LAG) to remove the staff lines and to perform primitive detection. After symbol segmentation using the primitive information, we use a covariance-matching method to estimate the similarity between every symbol and pre-defined templates. This method generates the three hypotheses with the highest scores for likelihood measurement. We also add a global consistency (time measurements) to verify the three hypotheses in accordance with the structure of the musical sheets; one of the three hypotheses is chosen through a final decision. The results of the experiment show that our proposed method leads to promising results.

Technology is the most important determination factor on firm`s competitiveness. It helps firms to secure sustainable competitive advantages. Therefore Korean electronics part firms have increased their R&D investment since the 1990s. But their R&D management capabilities seem to be low level. Empirical study was undertook to verify factors that effect on R&D performance with enhancing R&D management capabilities. To accomplish the purpose, data collected valid samples in Seoul and Kyunggi Province. Using SPSSWIN 10.0package, regression analysis was used to verify hypotheses. This study verify that important factors of 4th R&D generation effect on improving R&D performance. Therefore Korean electronics firms must learn advanced firms in developed countries. Based on learning and accumulating R&D management capabilities, Korean electronics part firms should establish their firm-specific R&D management model.

This study examines the effects of dependence and conflict on organizational performances in partnership, qualitatively (trust) and quantitatively (sales) under four control variables (period of business, number of goods, competition density, and number of employees). Also, this study presents termination cost and alternative attractiveness as the antecedents of dependence, goal incongruity and unfairness as the antecedents of conflict. As the results of analysis with survey data from 360 distributors in manufacturer-distributor partnership, 7 hypotheses are supported and 2 hypotheses are rejected. The results of structural equation modeling (SEM) verify that termination cost increases dependence, that alternative attractiveness reduces dependence, that goal incongruity and unfairness increase conflict, that dependence reduces conflict, that dependence increases trust, and that conflict reduces trust. However, unexpectedly, dependence reduces sales, and conflict has no impact on sales. The results of this study provide insightful implications theoretically and managerially to scholars and practitioners interested in partnership.

Nowadays, Customer Relationship Management (CRM) has been a competitive edge of many companies. It is critical for companies to get and maintain profitable customers. For the purpose of sustaining this competitive edge, companies should manage the Customer Information (CI) more effectively The major goais of this research are 1) to identify the activities of the Customer Information Management (CIM) and the factors influencing on the CIM, 2) to show the relationship between the proficiency of the CIM and the CI Quality, and 3) to verify the mediating effects of the proficiency of the CIM Process between the influencing factors and the CI Quality. An empirical study was undertaken to test the hypotheses with data from 65 companies. Multiple regression analysis and ANOVA were employed to test the hypotheses. We found that 1) there are 6 activities in the CIM process and 5 factors affecting the CIM, 2) the proficiency of the CIM process is closely related to the CI Quality, and 3) the proficiency of the CIM process plays the mediator between the influencing factors and the CI Quality.

The purpose of this study was to verify working hypotheses of effective management proposed by Sharpe and Winter(1991). For this purpose Managerial Effectiveness Scale(MES) developed and investigated relation with family life satisfaction. MES was divided into four conditions, performance-condition, timing, high level, and middle range and was included twenty-five managerial elements. Conditions of MES were highly correlated one another. It was assumed that four conditions related to promote synergistic effectiveness of managerial actions. Also, MES was positively related with family life satisfaction. It was suggested that effective management actions should improve should improve satisfaction of family life in general, and so family needs and goals should actualize through effective managerial-processes.

An efficient corner matching algorithm is developed to minimize the amount of calculation. To reduce the amount of calculation, all available information from a corner detector is used to make model. This information has uncertainties due to discretization noise and geometric distortion, and this is represented by fuzzy rule base which can represent and handle the uncertainties. Form fuzzy inference procedure, a matched segment list is extracted, and resulted segment list is used to calculate the transformation between object of model and scene. To reduce the false hypotheses, a vote and re-vote method is developed. Also an auto tuning scheme of the fuzzy rule base is developed to find out the uncertainties of features from recognized results automatically. To show the effectiveness of the developed algorithm, experiments are conducted for images of real electronic components.

In this paper we consider the problem of testing statistical hypotheses for unknown parameters in nonlinear regression models and propose three asymptotically equivalent tests based on regression quantiles estimators, which are Wald test, Lagrange Multiplier test and Likelihood Ratio test. We also derive the asymptotic distributions of the three test statistics both under the null hypotheses and under a sequence of local alternatives and verify that the asymptotic relative efficiency of the proposed test statistics with classical test based on least squares depends on the error distributions of the regression models. We give some examples to illustrate that the test based on the regression quantiles estimators performs better than the test based on the least squares estimators of the least absolute deviation estimators when the disturbance has asymmetric and heavy-tailed distribution.

Purpose - The convenience store business sector in South Korea has contributed to economic growth and job creation, and the growth potential of this market segment remains very high. In addition, service value is a more important factor than price in determining purchase intention. Research in the convenience store market is relatively very low compared to other retail sectors. In particular, research on service quality for the convenience of retailers who examine and analyze customer behavior and service quality factors used in the convenience store side of the situation is very inadequate. We have investigated the relationship of store service quality, service satisfaction, and store loyalty. In addition, we have examined the way service value moderates the relationship among these variables. Research design, data, and methodology - The questionnaire was developed using modified and supplementary questions based on the KD-SQS and RSQS models. The study suggested a theoretical model composed of 15 hypotheses on the relations between theoretic variables, and surveys conducted with consumers in discount stores in the Seoul and Gyunggi Metropolitan area in order to verify the hypotheses. We used the SPSS/PC statistical packages to analyze the results. The number of surveys used was 227. Moreover, a structural equating model was also used to analyze the reliability and validity of the composing elements and to verify the suggested hypotheses. Results - The overall results of this study are as follows. First, all service quality elements have a significant effect on service satisfaction. Second, all service quality elements have a significant effect on store loyalty. Third, service satisfaction has a significant effect on store loyalty. Finally, when the participants were divided into high and low service value the results of the multiple regression analyses showed that only the relationship between policy of service quality and satisfaction, and human interaction and policy of service quality and loyalty were significant. The implications are discussed based on the findings of the study. Conclusions - First, through direct hypotheses testing, we confirmed that the convenience service quality positively impacts the service satisfaction and loyalty of buyers. In particular, the reliability, origin benefit, and promotion were found to have more influence on satisfaction and loyalty of consumers of a convenience store. Further, for the service quality of the convenience for the consumer loyalty, greater human interaction was a high-value and statistically significantly higher than the degree of improvement in consumer loyalty. This underscores the importance of education and human services management of employees working in a convenience store. In particular, frequent changes in personnel generate results that negatively impact loyalty with customers. These results may lead to a serious problem in the economics of the store. Therefore, it should enhance the value of services through the establishment of training and compensation for employees. In addition, a certain educational level is required as well as a basis for compensation and retention.
