The objectives of this study were to examine effects of B2B e-commerce on the material management by comparing the performance of B2B and non-B2B hospitals, and surveying the extent of the objective of B2B implementation was achieved and success and failure factors of the implementation. Managerial data from six hospitals, three B2B and three non-B2B, and survey data from 107 employees involved in the material management at the study hospitals were analyzed. The number of employees at the department of purchasing, time spent for placing order, cycle time from order to delivery were better at the B2B hospitals, and employees satisfaction with the material management system was significantly higher in the B2B hospitals than in the non-B2B hospitals as well. However, intended effects of B2B e-commerce in wider areas of the material management such as inventory management and sharing of business information were not substantiated in this study. The study results indicated that B2B e-commerce in the study hospitals improved work efficiency and effectiveness in the area of procurement, and implied needs for an ERP-type system and process reengineering with the implementation of B2B e-commerce to obtain wider ranges of effects in the material management. Also the study results implied a need for communication with employees during the course of implementation for the system success. 제목: 기업간 전자상거래 도입 효과김동수, 홍성윤1, 박하영가톨릭대학교 의료경영대학원, 성모병원 간호부1

김동수 空軍士官學校 2003 論文集 Vol.51 No.-
War Syndrome indicates unexplained diseases and clinical symptoms revealing to veterans during or after war. This study reviewed causeless diseases and clinical symptoms of war syndrome, which is unfamiliar to the Korean military, and investigated major environmental risk factor associated with war syndrome. Environmental risk factors were physiological and psychological stress, chemical and biological warfare, injection of vaccines or antidote enhancer, extreme physical environment, and exposure to chemical by-products. Comparing to other wars, Gulf War was lasted very short time period, and use of chemical and biological warfare was not reported. However, Gulf War veterans also have suffered by unexplained diseases and clinical symptoms without associations with body injury. Herein, I suggest that stress having long-term effect to health and disease without any relationship to body injury may bo major risk factor of war syndrome, Although war period is shortened in future war, a high level of stress induced by weapons of mass destruction may affect veterans health through change of body homeostasis and host-resistance to infectious agents.

고려시대 界首官의 범위에 대한 재론 : Reargument
김동수 전남사학회 2002 역사학연구 Vol.19 No.-
There is a discrepancy on the views on an extent of local government that provided Gyesugwan(界首官) during the Koryo Dynasty. It has been understood that administrators of three upper levels of local government-three capitals(kyung 京), eight provinces(mot 牧), and five regional military commands(tohobu 都護府)-were in charge of the job, until Professor Park Chong Ki(朴宗基) raised a new view encompassing garrisons(chin 鎭) and counties(hyun 縣) besides the three upper levels of government. Several years back, this writer defended the traditional view by arguing Park's view incorrect, and also argued that even among the three upper levels of government only selected ones were to work as Gyesugwan(界首官). Park, in response, raised a new argument, a revised one from his earlier view. Still insisting on his earlier argument, he added that Prime Local Administrator(Juhyun 主縣) selected among the governments served as Gyesugwan. This writer scrutinized the materials Park used for his argument, which includes, for instance, the matters on the selection of petty functionaries(Hyanggong 鄕貢) and other key officials. As a result, it is reassured that the previous argument made by this writer is correct.Some privileged officials selected out of the three upper levels of local government served as Gyesugwan.
