Recently, The business environment is very rapidly changed and complicated. Therefore, the companies are confront with the biggest difficulty. To overcome this difficulty, the management should be able to accomplish the human resources management and the efficient business management. Korean National Railroad(KNR) enterprise is public enterprise. KNR has a close association with national life as it carries out public works based on its public nature as well as purses the corporate spirit. For that reason, KNR has a great spin-off on national economy and exerts a tremendous impact on the improvement of productivity around the industries and the international competitiveness at aspect of efficiency resulting from business rationalization. Railroad system can be described as organic. Engine drivers take a great role in this system. According the psychology and the Organization Behavior, the decision maker's attitude, personality and employee' work satisfaction have influence on performance. The purpose of this study is to examine the engine drivers' Attitude, Personality and Work satisfaction which influence on the efficient business management.

Intensified global competition and radically new production technologies have made accurate product/service cost information crucial to competitive success. An Information system is therefore a framework by which resources are coordinated to convert inputs into outputs, in order to achieve the objectives of an enterprise. The objective of this study is to analyze the cost accounting systems of the Korean Railroad(KR). The efficient cost accounting systems can build up the foundation of rational railroad management. The cost accounting systems will produce more useful cost information. The reason is that setting up the subsystems and multiple cost objects properly will provide more accurate cost information.

위 유문동근 K^+ - 경축에 미치는 Vanadate의 효과

Effects of vanadate on the spontaneous contraction and the high K^+-induced contracture of guinea pig’s pyloric antral smooth muscles were observed in the various Na^+ and/or Ca^+ of bathing solutions. Following results were obtained; 1. Basal tension and developed tension of the spontaneous activity were increased by vanadate and the membrane potential tended to be depolarized. 2. Phasic contracture increased, tonic contracture decreased as the outside K^+ concentration increased and the both components were increased by vanadate. 3. In the case of absence of K^+ and/or Na^+, the contracture were hardly developed and the spontaneous, rhythmic contraction were sustained. 4. Effects of vanadate on the K^+-contracture and the Ca^2+-sensitivity of the Phasit and tonic components were prominent in the presence of Na^+. The above results suggested that vanadate would increase the voltage-dependent calcium current in smooth muscle cells of the pyloric antrum.

Vanadate가 집토끼의 심근수축력과 활동전압에 미치는 효과

Rabbit papillary muscle preparations were used to investigate the effects of vanadate on isometric contractility and variabilities of action potential. To record the myocardial contractility and action potential of rabbit papillary muscles, 3M KCI-filled glass microelectrodes were directly introduced into the muscle cells. The following results were obtained: 1. By increase of concentration of vanadate, myocardial isometric contractility increased but action potential did not change. 2. In case of preparation with the calcium antagonist(Diltiazem) myocardial contractility decreased and the overshoot potential and APD50 also decreased. 3. In case of preparations simultaneously with vanadate and Diltianzem, the effect in case of initial treatment with vanadate was completely reversed ay later treatment with Diltiazem. Above results could be interpreted as that the inflow of calcium ion was increased at the myocardial cell membrane level and then the myocardial contractility was increased by vanadate.

Belief revision involves integrating new information with the current belief. It is a ubiquitous human activity. A critical feature of belief revision lies in its sequential nature. Railroad system can be described as organic. Engine drivers take a great role in this system. Recently, Hogarth and Einhorn(1992) have posited a belief-adjustment model for updating beliefs. Based on a sequential anchoring and adjustment strategy, the model is important for decision makers. The sequential nature of information processing is affected by some task variables. This will be mainly explained in this paper. The purpose of this study is to examine the engine drivers' belief revision process and factors which influence on the belief revision process. The factor is the experience. Thereby, this will contribute to the study of engine drivers' behavior. The result of this study is summarized as follows. The difference of belief revision is due to the experience level.
