An Examination of an IT Turnover Model in IT Service Settings: Evidence from Exit Interview
손윤환,이은영,이명주,조봉순 한국서비스경영학회 2018 서비스경영학회지 Vol.19 No.5
The objective of this study is to explore the mechanism behind turnover among IT service professionals. The current study investigated employee turnover by verifying and extending the IT turnover model in IT service setting and suggested possible factors. A Korean IT service company was selected for examination. Exit interview data collected for 6.5 years were used for research purposes(n=81). The results suggested that the model was a viable guideline to investigate IT service turnover. More specifically, pay and demographic factors including gender, education, organizational tenure were viable predictor for turnover of IT service professional. Also we found factors on related to organizational support, i.e., communication, recognition and relational support were important predictors for turnover in IT professionals which were not included in the model.

How Can a CEO Win The War for Talent? : The Effect of Employee Past Performance on Turnover
이명주,손윤환,조봉순,김현옥 한국전문경영인학회 2018 專門經營人硏究 Vol.21 No.4
This study verified the effect of job performance results before the turnover on the turnover causes using the exit interview data. By classifying the turnover causes into the pull and push factors, the research model was presented that turnover causes were shown differently based on the job performance results before the turnover, and that the job alternatives and job satisfaction were affected by turnover causes. Six year data of exit interviews of a KOSDAQ company which provides the software services in Korea were examined to verify the model and 102 leaver responses were included in the analysis. As the result, pull factors were the main turnover causes for the high-performers and the pull factors had the positive effect on the job alternatives. Push factors were the main turnover causes for the low-performers and the push factors had the negative effect on the job satisfaction. Based on the study result, we suggested the theoretical and practical implications, and the future direction of the study.
Some applications for the difference of two CDFs
홍종선,손윤환 한국데이터정보과학회 2014 한국데이터정보과학회지 Vol.25 No.1
It is known that the difference in the length between two location parameters of two random variables is equivalent to the difference in the area between two cumulative distribution functions. In this paper, we suggest two applications by using the difference of distribution functions. The first is that the difference of expectations of a certain function of two continuous random variables such as the differences of two k th momentsand two moment generating functions could be dened by using the difference between two univariate distribution functions. The other is that the difference in the volume between two empirical bivariate distribution functions is derived. If their covarianceis estimated to be zero, the difference in the volume between two empirical bivariate distribution functions could be defined as the difference in two certain areas.
