In this article, the author studied the relationship between the Sovereign and the follower in Juyeok which contained some eliments, such as Eum-Yang, Soseong 8 gyae, Daeseong 64 gyae. In Juyeok, the 'Sovereign 5 hyo' (1) shows distinctiveness in basic characteristics whether they are Eum or Yang(high level classification), (2) shows characteristics of Soseong-gyae to which they belong(middle level classification), (3) shows different characteristics according to Daeseong-gyae's circumstances(low level classification). Five Yanghyo are regarded as male sovereign having masculinity, whereas five Eumhyo are female sovereign with femininity. Gungyae is the most 'sturdy type leader' who possesses dignity and has good judgement. Taegyae, the blessing type leader, holds affection and calmness within sturdiness. Rigyae is gorgeous and passionate 'enthusiastic type leader'. Jingyae, the pioneering leader, bravely starts ascending in Eum-dominant atmosphere. Songyae has the virtue of hesitancy and concession, known as the leader of humbleness. Gamgyae always stay low and calm, regarded as a leader of sense. Gangyae shoots up from the earth, meaning a leader of strong will. Gongyae, embracing type leader, is straight and square, though it tries to embrace everything. Daeseong-gyae(64gyae) is formed by Soseong-gyae piling another Soseong-gyae. The characteristics of Soseong 8gyae are embodied in two-level form, the top(inner gyae) and the bottom(outer gyae). Simultaneously, the whole characteristics of 대성괘 are embodied. The Sovereign should show his/her leadership based on the 'characteristics of Daeseong-gyae'. These characteristics are the contingency from 'contingency leadership'. In other words, they are preconditions which leaders ought to admit.

High technique growth of modem times and high industrial facility in consequence of buildings demand for electric power of an extensive scale with stability supply and maintenance of high quality. But, power system always have risk of network contingency. When power system break out disturbance, it circumstantially happen like uncontrolled loss of load developing from of cascading. Severely which would be raised wide area blackout, plan to prevent, which make stability through a little of load shedding and multi-level UnderVoltageLoadShdding should work. This paper presents target, sensitivity of bus voltage have choose appropriating load shedding location and load shedding decision making logic with considering rate of change of voltage have studied multi-level under voltage load shedding scheme. Calculation of rate of change of voltage applied method of least square. As a result, we are studied an dynamic analysis of 2008 summer peak data. We have been known that network analysis is a little development and developing UnderVoltageLoadShedding scheme.

In this research, risk factors which can raise project cost are identified in the initial stage and picked out through the decision maker's baseline. And also this probable risks are implemented to the project cash flow to estimate the contingency and to build a risk management system in the level of project. The risks that affect the projects profits were classified in two categories in the risk checklist. Firstly, financial risks derived from the external economic conditions for example exchange rate, escalation, interest rates etc. are analyzed through the stochastic methods, Monte-Carlo Simulation. Secondly, the project individual risks which are come from the project characteristics, for example country risk, clime, owner etc., are evaluated using the utility curve of the decision maker. Finally these risk analysis methods are used to forecast the actual project cash flow and final profit.

Managers are required to adopt and implement the human resource management practice that fit firm's strategy the most, so that optimize overall performance. However, the time and relative resources that any firm has are limited, which demands managers to understand the relative importance of all sorts of HR practice and promote them in an order of their relative importance. This study follows the universal perspective and contingency perspective(according to firm size and strategy type), try to identify the most effective HR practice on performance as well as their relative importance by "CART Ensemble" analysis. The results are as follows. From universal perspective, firms always need to high level of integration between strategy and HR department, decision making participation, autonomy of speed of working, and autonomy of way of working. Contingency perspective also suggested the importance of integration between HRM and strategy. But others are different case by case. This study suggests useful implications for managers.

Contingency tables are used to compare counts of n-grams to determine if the n-gram is a true collocation, meaning that the words that make up the n-gram are highly associated in the text. Some statistical methods for identifying collocation are used. They are Kulczinsky coefficient, Ochiai coefficient, Frager and McGowan coefficient, Yule coefficient, mutual information, and chi-square, and so on. But the main problem is that these measures are based ell the assumption of a nor-mal or approximately normal distribution of the variables being sampled. While this assumption is valid in most instances, it is not valid when comparing the rates of occurrence of rare events, and texts are composed mostly of rare events. In this paper we have simply reviewed some statistics about testing association of two words. Some randomization tests to evaluate the significance level in analyzing collocation in large corpora are proposed. A related graph can be used to compare different lest statistics that ran be used to analyze the same contingency table.

Existing knowledge regarding the antecedents of the entrepreneurial orientation (EO) of firms is somewhat limited given the emphasis on its performance implications. To address this research gap, this study aims to explore the drivers of entrepreneurial orientation using the resource-based view (RBV) and contingency perspective. To test our hypotheses, this study uses 225 survey data collected from Korean exporters. Results show that the level of entrepreneurial orientation varies depending on organizational characteristics such as firm size and internationalization of the firm. Our findings also support the tenet of the contingency perspective by showing the influences of environmental characteristics such as technological turbulence and market uncertainty on the entrepreneurial orientation of firms. Our empirical research provides academic and practical implications for the field of entrepreneurship.

During the past decade a great deal of attention has focused on the impact of IT investment. However, many related studies have frequently generated controversial or inconsistent results. These results imply that the relationship between IT investment and performance is complex and multifaceted. And empirical studies with new analytical techniques are badly needed to examine the way IT investment interacts with various organizational and environmental elements to influence corporate performance. Accordingly a study of IT investment needs to make a contingency approach to determining the level of IT investment based on the competitive strategy in a macro perspective. The basic purpose of this research is to analyse the relationship between IT investment and IT effectiveness and to identify the moderating effect of competitive strategy in the relationship. The results showed that there is no relationship between IT investment and IT effectiveness, and the competitive strategy can be considered as a significant moderating variable between IT investment and IT effectiveness.

On-line dynamic security assessment is becoming more and more important for the stable operation of power systems as load level increases. The necessity is getting apparent under Electricity Market environments, as operation of power system is exposed to more various operating conditions. For on-line dynamic security assessment, fast transient stability analysis tool is required for contingency selection. The TEF(Transient Energy Function) method is a good candidate for this purpose. The clustering of critical generators is crucial for the precise and fast calculation of energy margin. In this paper, we propose a new method for fast decision of mode of instability by using stability indices. Case study shows very promising results.

In this study, we suggest a new perspective on the linkage between alliance portfolio diversity and innovation performance based on a contingency approach. Using a longitudinal data set on alliance portfolios and patents of 182 firms in the U.S. manufacturing industries, we examined that alliance portfolio diversity has a U-shaped relationship with firm-level innovation. Internal value creation capabilities in terms of routine and ability are found to moderate the relationship between alliance portfolio diversity and innovation performance: Organizational search routine strengthens the relationship of alliance portfolio diversity and innovation performance while technological capabilities weaken and flip the relationship.
