This paper describes the differences of the information system's success factors to improve the end-user's performance according to the job characteristics. A modified model of DeLone and McLean's IS success model is proposed with the two added variables of the top management concern and the IS department support. The model is validated using data collected from a field study of 3872 users on 3 Korean companies. ANOVA, correlation analysis, and stepwise regression are used to test research hypotheses. The results of the study indicate the following implications. First the top management concern and the IS department support have the significant relation with the system usage and the user satisfaction. Second, the system quality has an influence on the user satisfaction more than on the system usage. And the information quality has an influence on the system usage more than on the user satisfaction. Third, the system usage has more relations to the user's performance in the logistics function and R&D function. The user satisfaction has more relations to the user's performance in the sales and the A/S function. Therefore information system strategy to increase the user's performance must be differentiated according to job characteristics.

Purpose: The purpose of this study was to examine the usage of CAD/CAM, which is one of dental technologist duties, in an effort to look for any possible changes in the usage of CAD/CAM. It's specifically meant to compare the results of this study with those of Lee Jong-do, Park Kwang-Sig(2011)'s study in March, 2011, to determine if there were any changes over the past four years. The selected variables that were investigated were the ownership of CAD/CAM, awareness of it, the route of acquiring the first information on it, the merits and demerits of its usage, usage experience and educational experience about it. Methods: An online survey was conducted on the dental technologists who worked in urban communities including metropolitan cities to find out the usage of CAD/CAM in 2015 from July 15 to 31, 2015, after existing questionnaire items were modified. The collected data were analyzed by IBM SPSS statistics 22.0, and statistical data on frequency, percentage, mean and standard deviation for each item were obtained. To figure out the characteristics of the subjects and the relationship between their occupational characteristics and the usage of CAD/CAM, crosstabs, independent-samples t-test and one-way ANOVA were utilized. As for the usage of CAD/CAM in 2011, the results of Lee Jong-do, Park Kwang-Sig(2011)'s study were selected, and then a comparative analysis was made. The level of significance was all set at .05. Total 250 questionnaires were distributed to them, and 190(76.0%) were returned. After excluding 23 whose answers were uncertain or seemed to lack reliability, total 167(66.8%) were used in final analysis. Results: As a result of analyzing the usage of CAD/CAM that was one of dental technologist duties, there was a great increase in the ownership of CAD/CAM in their workplaces from 2.4 percent in 2011 to 71.7 percent in 2015, and there was an improvement in awareness about it and the necessity of its usage as well. In 2011, the Internet and mass media were the most common route that they got to know about it. They had a strong tendency to acquire related knowledge through education in 2015, and there were some changes in the products that they used or preferred. In both years, the great merit of CAD/CAM was the simplified manufacturing process of restoration, and it had another great advantages in 2015 such as the improved quality of restoration or improved environments for dental technology. Concerning disadvantages, high price was a big problem in 2011. In 2015, not only price but the burden of material costs, frequent breakdown, poor demand among dental clinics and a lack of CAD/CAM professionals were pointed out a lot. In the future, this researcher intends to make research to seek ways of improving CAD/CAM professionals. Conclusion: There was more awareness of CAD/CAM in 2015 than in 2011 when the changes in awareness of it were analyzed, and the finding suggest the necessity of sustained education and concern.

Objectives : This study aimed to analyze the characteristics of uninsured herbal medicine(UHM) users and the economic and social barriers of UHM utilization. Methods : We used the Korea Health Panel Data, representative national survey on medical utilization and cost, provided by National Health Insurance Service and Korea Institiute of Health and Social Affairs. The frequency analysis was used to identify the characteristics of the respondents, and the cross-analysis (${\chi}^2-test$) was used to verify the relationship between their characteristics and the usage of UHM. In order to analyze the determinants of using the UHM considering the individual's characteristics, logistic regression analysis and multiple regression analysis were conducted for those who used the Korean medicine (KM) outpatient service in 2015. Results : The usage of UHM was significantly lower for those (1) who's age of 20 to 65; (2) who have the university or higher education degree; (3) who live in Jeju province, and (4) who bought the herbal medicine for other health related purposes. On the other hand, the usage of UHM for those (1) who have the first quintile of household income; (2) who have the chronic respiratory disease; (3) who have been taking the medicine for health promotion purpose for more than 3 months and (4) who have purchased the food which has health promotion function was significantly higher than others. The patients who have chronic musculoskeletal diseases accounted the most among the UHM users. Conclusions : There was the considerable inequality in the usage of UHM among household income groups, which provides policy rationale for UHM to be covered by national health insurance. To facilitate the coverage expansion, restrictive covering model can be considered for children and adolescents, or for patients with muskuloskeletal diseases who have the high demand for UHM.
