  • As the laws of physics are expressed in a manner that makes their invariance under coordinate transformations manifest, they should be written in terms of tensors. Furthermore, tensors make manifest the characteristics and behaviors of electromagnetic fields through inhomogeneous, anisotropic, and compressible media. Electromagnetic fields are expressed completely in tensor form, Fαβ, which implies both electric field ${\overrightarrow{E}}$ and magnetic field ${\overrightarrow{B}}$ rather than separately in the vector fields. This study presents the Mathematica platform that generates and transforms a second-rank antisymmetric field-strength tensor Fαβ and whiskbroom pattern in Minkowski space. The platforms enhance the capabilities of students and researchers in tensor analysis and improves comprehension of the elegant features of complete structure in physics.

  • The partial least squares (PLS) method is popularly used for estimating the structural equation model, but the existing algorithm may not be directly implemented when probabilities are involved in some constructs or manifest variables. We propose a structural equation model including the brand choice as one construct having brand choice probabilities as its manifest variables. Then, we develop a PLS-based algorithm for the structural equation model by utilizing the multinomial logit model. A case is introduced as an application and simulation studies are performed to validate the proposed algorithm.

  • Threat is one special type of communication whereby one conveys opinion, knowledge, or attitude to another with an intention to influence and modify the latter's opinion or behavior. This research aims at identifying the antecedents and the effectiveness of threats applied in the process of purchasing decision-making. The research model integrates constructs derived from the literature of diverse discipline. The framework suggested explains the relative effects of threats, is tested empirically to verify the impacts on the influenced target's opinions and behaviors in buying centers. Data are collected from CAPM's members in Taiwan, and 208 respondents served as targets in the interpersonal relationships. LISREL findings indicate that threats are effective in winning a target's compliance. Additionally, influencing source's characteristics affect the choice of threats more strongly than target characteristics do. The relative ability of dependence on the source to cause manifest influence is even more significant than that of threats. Overall, the results of this study appear consistent with behavioral theories and research.

  • The fate of Telfairia occidentalis seed Agglutinin, TOA, has been monitored during germination. While the level of the Agglutinin in the cotyledons decreased sharply in the first three days to about half of the initial level, it stabilises at this level for the following twelve days. In this interval, Agglutinin activity becomes manifest in the radicle on the fourth day, peaking on the fifth and decreasing rapidly thereafter. In the plumule, the lectin activity becomes manifest on the sixth day, peaks on the seventh and decreases rapidly thereafter. No lectin activity is detectable in any plant tissue including the rump of the cotyledons twenty-seven days after germination. The implications of these observations on the possible role of lectins in plants are discussed.

  • The purpose of this study was to examine the cause of new curriculum which has always problems even though it is revised repeatedly and to propose an fundamental alternatives to solve these problems. In this study, the cause of these problems considered the wrong point grasping the knowledge of curriculum contents. In other words, the knowledge of curriculum contents is understood as the point of utility rather than the curriculum are constructed as the form reflecting nature of knowledge. According to do this, Bruner's structure of knowledge is of help. The structure of knowledge which is well known existing is understood as manifest aspect but from now on, we have to be concerned about tacit aspect. In this case, the structure of knowledge has characteristics as an integrated knowledge.

  • In recent years, Korea's aviation industry has been developing rapidly due to the emergence of low-cost airlines. In order to survive in such competition, airlines are making various efforts to save the operation cost as much as possible. Fuel costs account for more than 25% of operating costs. For airlines, reducing aircraft fuel costs is an important part of improving profitability. In this study, analyzing the difference weight between flightplan and W&B Manifest for calculated the fuel that was unnecessarily loaded. As a method to calculate the unnecessary fuel was used by Airbus company flight planning program.

  • Since 1998, government-led Korean venture business boom now proceeds into the stage of market-oriented venture business growth. At such a moment, this research is to clarify the relations between the Critical Success Factors of Korean venture businesses, based on domestic and foreign literature surveys and inquiry surveys over domestic venture capitalists. This research starts from the necessity to overcome the limits of the existing researches by uni-dimensional Korean venture businesses and to manifest the multi-dimensional relations between the success factors from the various viewpoints. And this research adopts System-Dynamics methodology to manifest and utilize relations among those factors, avoiding the existing metrical approaches. This research can be called a new approach to the current ecosystems of Korean venture in which whether venture businesses in Korea succeed is considered to depend on the list on the stock market. For this, this research implemented verification analysis through the simulations of each factor at various levels to build causality map which clarifies the causality of success factors of venture businesses through the System-Dynamics methodology and to utilize it as a way of support to decision-making of venture businesses. This research will be able to suggest the reactions depending on various internal and external situations. This research tried to manifest the causality map of each factor on the basis of inquiry surveys and literature surveys to clarify Feedback among each factor by the SD methodology and simulate it. This research will be a basis to establish the chance to bolster up the still fragile probing research into success factors of substructure of venture businesses through the suggestion of possibility as an efficient analysis framework via the verification of SD methodology and the utilization of results of this research.

  • This study is to vindicate the vacation of arbitral awards in the United States. It focuses on the harmony of case law with statutory law of the United States. Until the early twentieth century, the American legal system, having adopted the English common law view, harbored a hostile attitude toward arbitration. The purpose of the Federal Arbitration Act (FAA) of the United States, enacted in 1925, was to eliminate the hostile attitude of courts toward arbitration. Congress is to enforce arbitration agreements into which parties have entered and to place arbitration agreements upon the same footing as other contracts. The structure of grounds for vacating arbitration awards has two layers. One is of vacating grounds with statutory origins, such as the FAA and the Uniform Arbitration Act, and the other, of vacating grounds originating from a nonstatutory, case law background. For a while, vacatur based on case law has coexisted with vacatur on statutory grounds for arbitration awards. After the Supreme Court decision in Hall Street Associates, L.L.C. v. Mattel, Inc., however, the justification of vacating based on case law has weakened. Post-Hall Street decisions of circuit courts show ways to deal with manifest disregard of the law. One of them is the harmonization of the case law grounds for vacating with the statutory grounds. It seems that the manifest-disregard-of-law and public-policy exceptions show a possibility of survival after Hall Street. However, other nonstatutory grounds for vacation of arbitration awards have no firm basis after Hall Street.
