This paper is focused on management control system. From a management control perspective, strategies should be viewed as useful, but not absolutely necessary, guides to the proper design of an MCS. When strategies are formulated more clearly, more control alternatives become feasible and it becomes easier to implement each form of management control effectively. The common and important category of controls are action controls, personnel and cultural controls, and results controls. Action controls involves ensuring that employees perform(or do not perform) certain actions that are known to be beneficial(or harmful) to the organization. Personnel and cultural controls take steps to ensure that employees will control each others' behaviors. Results controls involve rewarding individuals(and sometimes groups of individuals) for generating good outcomes or punishing them for poor outcomes. The results controls of ROI-type measure cause to make managers excessively short- term oriented, or myopic. When managers' orientations to the short - term become excessive -when the management are more concerned with short-term profit than entity value-the managers are said to be myopic. We car, solve myopic problem by introducing AR(abnormal return), near-perfect indicators of value creation. The results - control ideal would be to hold all employees accountable for the wealth they individually create(or destroy) for the owners of the entities in which they work. This ideal is approachable for top management of publicly traded corporations because for these organizations, the wealth created(returns to shareholders) can be measured directly for any period(such as a year, a quarter, or a month) as the measurement period pin(or minus) the change in the market value of the stock.

Molecular imaging provides a visualization of normal as well as abnormal cellular processes at a molecular or genetic level rather than at a anatomical level. Conventional medical imaging methods utilize the imaging signals produced by nonspecific physico-chemical interaction. However, molecular imaging methods utilize the imaging signals derived from specific cellular or molecular events. Because molecular and genetic changes precede anatomical change in the course of disease development, molecular imaging can detect early events in disease progression. in the near future, through molecular imaging we can understand basic mechanisms of disease, and diagnose earlier and, subsequently, treat earlier intractable diseases such as cancer, neuro-degenerative diseases, and immunologic disorders. In beginning period, nuclear medicine started as a molecular imaging, and has had a leading role in the field of molecular imaging. But recently molecular imaging has been rapidly developed. Besides nuclear imaging, molecular imaging methods such as optical imaging, magnetic resonance imaging are emerging. Each imaging modalities have their advantages and weaknesses. The opportunities from molecular imaging look bright. We should try nuclear medicine continues to have a leading role in molecular imaging.

Global climate change caused by industrialization has caused abnormal weather conditions such as urban temperatures and tropical nights, urban heat waves, heat waves, and heavy rains. Therefore, the study tried to analyze climate conditions and weather conditions in the streets and analyze climate factors and meteorological factors that lead to inconvenience to citizens. In the case of trees, the overall temperature, surface temperature, solar irradiance, and net radiation were measured low, and the temperature was lower in the Pedestrian road than in roads. The dry bulb temperature, the black bulb temperature, and the wet bulb temperature for the thermal evaluation showed the same tendency. In the case of thermal evaluation, there was a similar tendency to temperature in WBGT, MRT, and UTCI, and varied differences between types. Although the correlation between the meteorological environment and the thermal environment showed a statistically significant significance, the difference between the measured items was not significant. The study found that the trees were generally pleasant to weather and thermal climate in the form of trees, and the differences were mostly documented.

The Operation of high speed train in year 2004 bring about a great change in railroad industry. Especially in railroad construction field we have acquired great Know-how. And up to now we are building up operation skills. But the high speed train system are totally imported, so it is necessary to investigate some of the equipment based on our own environment. In case of Toughened Glass Stem Insulator, we don't have any application case in domestic and limited in abroad. So there must be some characteristic estimation. The estimation was made in three different ways. First electrical field cause, Second physical field cause and finally in circumstance cause. In Electrical field cause, amplitude and number of time for abnormal peak voltage data are collected. And in physical field cause, amplitude and trend of vibration in to the insulator are examined. And I circumstance cause, possibility of flying gravel and ice clod are investigated. Through this basic data suitability for Toughened Glass Stem Insulator using in domestic will be accumulated.

Since REM sleep was found to be closely related with dream, efforts have been made to find the neurophysiological mechanism and the psychological meaning of dream. However, since most researchers have paid attention to dreams of adults, there are relatively few studies devoted to those of developing children. In the prevent study, we reviewed the previous studies and hypotheses about sleep and dream in various aspects and summarized the characteristics of sleep and dream of children in developmental domain as followings. (1) Sleep development : Across childhood, sleep architecture and sleep-wakefulness cycles are progressively changed toward the patterns of adult. They become similar to adult patterns only in their adolescence. Thus, the sleep event sconsidered as abnormal in adults may be normal in children. (2) Dream development : First, the content and meaning of the dream change with increasing age and develop in parallel with children's ego function, especially cognitive developmental stages. Second, for the children, the reality and the dream are on the continuous spectrum of 'reality-imitation-play-fantasy-dream'. Third, dreaming is the pure assimilation process for the children and through dreaming they can adapt and accomodate the reality without emotion.

Gait analysis is essential to identify accurate cause and knee condition from patients who display abnormal walking. Traditional linear tools can, however, mask the true structure of motor variability, since biomechanical data from a few strides during the gait have limitation to understanding the system. Therefore, it is necessary to propose a more precise dynamic method. The chaos analysis, a nonlinear technique, focuses on understand how variations in the gait pattern change over time. Eight healthy eight subjects walked on a treadmill for 100 seconds at 60 Hz. Three dimensional walking kinematic data were obtained using two cameras and KWON3D motion analyzer. The largest Lyapunov exponent from the measured knee angular displacement time series was calculated to quantify local stability. This study quantified the variability present in time series generated from gait parameter via chaos analysis. Knee flexion-extension patterns were found to be chaotic. The proposed Lyapunov exponent can be used in rehabilitation and diagnosis of recoverable patients.

Measurement time delay in the transfer alignment is very important. It has been well known that the time delay degrades the alignment performance and makes some navigation errors on the transfer alignment of slave INS(SINS). Therefore there are many schemes to eliminate that time delay but the compensation technique through the estimation by Kalman filter through modeling the time delay as a random constant is generally used. In the case of change over measurement time delay or the large measurement time delay, estimation performance in the existing compensation technique is degraded because model of time delay is not correct any more. In this paper, we propose the method to keep the time delay almost constant even though in the abnormal communication state and very small through feedback compensation using double buffer. Double buffer consists of two moving window to temporarily store measurements from master INS and slave INS in real time.
