This paper seeks to search for wisdoms that may be applied to modern leadership through Tasan Jeong Yakyong's ideology, ShilHak, from the Chosun Dynasty. The present period is referred as the period of transformation and innovation or the period of knowledge information The leadership appropriate for the current period is thus called revolutionary leadership. This leadership accomplishes its goals by influencing the constituent's values, ethics, behavioral norms, and visions based on the leader's moral values, knowledge, and information. Thus, the essence of this paper is in acquiring wisdoms of leadership by company revolutionary leadership with Tasan's life. Tasan pursued change and innovation in a time where Chosun was in a state of decay by following the flow of world powers towards the concept of studying truth based upon facts such as changing the system of thought, reforming legislation, and developing technology. Moreover, he gave courage and hope to the people by demonstrating such leadership in practice. In addition, despite false accusations and spending 18 years in exile, he showed revolutionary life as an active intellectual by leaving 542 volumes of writing through his 'value innovation' that he "pursue things only for the people and the state." Consequently, the paper first deals with what kind of leadership is required for a leader in the position of a general and examines the kind of leadership capacity demanded. Subsequently, Tasan 's revolutionary life and hints of leadership messages in MokMinSimSuh are examined. Thus, this paper is centered upon the leadership of generals regarding how MokMinShimSuh may be applicable to modern leadership.

Purpose : This study was undertaken to determine the preoperative predictors of mortality and morbidity after lung cancer resection. Method: During the period from October 1, 1995 to August 31, 1996, a prospective study was conducted in 92 lung resection candidates diagnosed as lung cancer. For preoperative predictors of nonpulmonary factors, we considered age, sex, weight loss, hematocrit, serum albumin, EKG and concomitant illness, and for those of pulmonary factors, smoking history, presence of pneumonia, dyspnea scale(1 to 4), arterial blood gas analysis with room air breathing, routine pulmonary function test. And predicted postoperative(ppo) pulmonary factors such as PPO-$FEV_1$, ppo-diffusing capacity(DLco), predicted postoperative product(PPP) of ppo-$FEV_1%{\times}ppo$-DLco% and ppo-maximal $O_2$ uptake($VO_2$max) were also considered. Results: There were 78 men and 14 women with a median age of 62 years(range 42 to 82) and a mean $FEV_1$ of $2.37\pm0.06L$. Twenty nine patients had a decreased $FEV_1$ less than 2.0L. Pneumonectomy was performed in 26 patients, bilobectomy in 12, lobectomy in 54. Pulmonary complications developed in 10 patients, cardiac complications in 9, other complications(empyema, air leak, bleeding) in 11, and 16 patients were managed in intensive care unit for more than 48hours. Three patients died within 30 days after operation. The ppo-$VO_2$max was less than 10ml/kg/min in these three patients, but its statistical significance could not be determined due to small number of patients. In multivariate analysis, the predictor related to postoperative death was weight loss(p<0.05), and as for pulmonary complications, weight loss, dyspnea scale, ppo-DLco and extent of resection(p<0.05). Conclusions: Based on this study, preoperative nonpulmonary factors such as weight loss and dyspnea scale are more important than the pulmonary factors in the prediction of postoperative mortality and/or morbodity in lung resection candidates, but exercise pulmonary fuction test may be useful Our study suggests that ppo-$VO_2$max value less than 10ml/kg/min is associated with death after lung cancer resection but further studies are needed to validate this result.
