A better selection model on management innovative enterprises is needed since the Korean government provides multi benefits to those selected enterprises. However, the selection model's propriety is suspicious because of the shortage of consideration of assessment items. In particular, the most important two assessment items, strategy and performance are suspected of multicollinearity because of high correlation scores. No consideration on multicollinearity among those items leads to erroneous selection which doubly counts the same components with different item names. The principle component analysis is applied to factor out the uncorrelated items. Using the resulted principle components, the new estimations are carried out. The comparison between estimated results from using principle components and non principle components shows that the present selection model overly considers the performance items compared to the real effect of items, which is a result of multicollinearity between performance and strategy.

In this paper we study triangle's properties related with angle bisectors, perpendiculars, circumcenter using the principle of the lever. We analyze proof method using the principle of the lever, and describe how to investigate intersection of segments, how to prove equalities and inequalities using the principle of the lever in triangle.

This paper shows the procedure to decide an optimal design principle for improving the disassemblability with considering of disassembly conditions. On the bssis of the disassembly mechanism of products and the structure of parts and subassembly, the disassemblability is classified into four categories: graspability, accessibility, transmission of disassembly power and handling. The weighting values of the influential factors are calculated by the method of AHP(Analytic Hierarchy Process). The disassemblability is evaluated quantitatively. We established some score tables for the evaluation. Using these score tables, several principles for higher disassemblability in accordance with work conditions can be decided. An optimal design principle can be found by the comparison with the total scores of some disassembly conditions.

With the realization that the police's personal information gathering activities can violate the authority to decide one's information guaranteed by the Constitution, many people are interested in the legal terms of the police's information gathering and handling. The police's personal information gathering activities imply both the purpose of public welfare and order and the risk of violation of basic rights of citizens, their effective balance is critical. In this respect, this study reviews the principle of proportion as a principle of control of personal information gathering and handling (police intelligence activities) by state to discuss its implications on legislation.

Bode principle is applied to carry out traffic control for rate based ATM network, which guarantees the higher buffer utilization, buffer overflow-free, and well utilization of bandwidth. The principle confirms the relationship between the threshold of buffer queue and the network bandwidth, as well as the relationship between the threshold of buffer and source input rate. Theoretic warrant of the buffer threshold is proposed. The reference range of source input rate is provided in theory, which makes the source end respond to the change of network state rapidly and dynamically, and then the effect of time delay to the traffic control is avoided. Simulation results show that the better steady and dynamic performances of networks are obtained by Bode principle.

The operation principle of an axial flux-switching hybrid excitation synchronous machine (AFHESM) is analyzed and its topology structures are proposed in this paper. After some comprehensive analysis of the operation principle to axial flux electrical machine, flux-switching electrical machine and hybrid excitation electrical machine, the operation principle of AFHESM is given. Combined with some typical topological structures of hybrid excitation electrical machine, some possible topological structures are proposed and some comprehensive comparisons are carried out. The analysis results show that the stator-separated AFHESM has some advantages such as less AM turns, less impact on the demagnetization of PM, less magnetic flux-leakage and higher efficiency compared to other topologies.

The main objective of this paper is to vindicate the Bayesian belief updating rule, i.e. conditionalization. For this purpose, I introduce first what I call Irrelevance Principle, and show that this principle is equivalent to conditionalization. In turn, the principle is vindicated by means of Bayesian confirmation theory. That is, I suggest some theses that Bayesian confirmation theorists should accept, and prove that if Irrelevance Principle is violated, the theses cannot holds.

Exergy is defined as the amount of work (entropy-free energy) a system can perform when it is brought into thermodynamic equilibrium with its environment. Exergy measures the distance from the inorganic soup in energy terms. Therefore, exergy can be considered as fuel for any system that converts energy and matter in a metabolic process. The aim of this study is to introduce structural dynamic modelling which is based on maximum exergy principle. Especially, almost ecological models couldn't explain algal succession until now. New model (structural dynamic model) is anticipated to predict or explain the succession theory. If the new concept using maximum exergy principle is used, algal succession can be explained in many actual cases. Therefore, It is estimated that structural dynamic model using maximum exergy principle might be a excellent tool to understand succession of nature from now on.

This paper seeks to provide a comprehensive review of the international rules of law on the obligations of confidentiality and its exceptions in international commercial arbitration, including the Riddick principle stemming from the common law jurisdiction. To this end, this article examines and analyzes developed countries' arbitration legislation including relevant case laws and the most recent leading institutional rules. Given the fact that the increasing use of discovery in international commercial arbitration and that the parties and practitioners in civil law countries are not familiar with the concept of the Riddick principle and its implied undertaking to a court, this article introduces the concept of the Riddick principle with some analysis for the recent case laws. Finally, this paper makes some suggestions to strengthen the compliance of confidentiality in international commercial arbitration by introducing new rules on confidentiality, inter alia, sanctions for breaching of the obligations of confidentiality.

This paper reviewed "unconscionability" as an exception to the independence principle of bank guarantees. Apart from fraud which has been recognized in most international jurisdictions, Uuconscionability would also be recognized as the exception to the legal principle, the so-called "fraud rule" or "an abuse of rights." Unconscionability exception is applied in the same manner as fraud and other exceptions to the principle of independence. The exception should allow guarantor to dishonor the drawings that abuse the independence principle. However, outright or manifest facts of the unconscionability must be established in order to apply the exception. Lots of arguments or conflicts may be caused in applying the unconscionability exception. Therefore, this study aims to prevent institutional abuses or to reduce the disputes from setting up the legitimate scope and standard for application of the exception by reviewing these procedural issues and problems under bank guarantee transactions. This paper also suggested practical implications and countermeasures for the institutional application.
