  • The three main purposes of this paper are to (1) identify critical success factors(CSF's) for electronic commerce(EC), (2) investigate the explanatory power of these CSF's on firm performance, and (3) compare differences in evaluating CSF's and explaining impact of CSF's on performance between Korean and U.S.A. EC managers. Through a literature review and interviews with managers in EC firms, a list of 16 CSF's consisting of 111 items was compiled. In the second stage, questionnaires were administered to managers of EC companies in Seoul, Korea and Texas, U.S.A. Survey results show that CSF's have very significant explanatory power for firm performance in both Korean and U.S.A. While security, privacy, technical expertise, information about goods/services, and variety of goods/services are the most explanatory CSF's in Korea, evaluation of EC operations, technical expertise, and ease of use show most explanatory power in U.S.A. This analysis confirms the fact that customers use EC if they feel comfortable about navigating EC for information about a variety of goods/services without technical difficulty and in a secure and private way.

  • Because the Korea-U.S. Free Trade Agreement (Korea-U.S. FTA) and the North American Free Trade Agreement (NAFTA) have an overlapping contracting party, the United States, their provisions have much in common. The investment chapters of these agreements, especially, show many similarities, and thanks to these similarities, it is likely that the Korea-U.S. FTA arbitration tribunal for investor-state disputes regarding the environment will put great weight on the NAFTA tribunals' interpretations of those similar provisions. Since the NAFTA tribunals have already handled many environment-related arbitration cases, their interpretations will help heighten the predictability of environment-related Korea-U.S. FTA arbitration cases. This paper analyzes the environment-related NAFTA cases in which the tribunal has issued an award, which are the Metalclad case, S.D. Myers case, Waste Management case, Methanex case, Glamis Gold case, and Chemtura case. According to this analysis, the most controversial NAFTA provisions have been Article 1102 (national treatment), Article 1105 (minimum treatment standard, fair and equitable treatment), and Article 1110 (expropriation). The NAFTA tribunals applied the requirement of these articles in a strict manner, reducing the possibility of finding a violation. After the aforementioned analysis, this paper proceeds to compare the national treatment, minimum treatment standard (fair and equitable treatment), and expropriation provisions of the Korea-U.S. FTA and NAFTA and to predict the impact that the environment-related awards under NAFTA can have on environment-related Korea-U.S. FTA cases. It is expected that the NAFTA interpretations of the national treatment and minimum treatment provisions are likely be used as they are, but not the interpretations of expropriation, because of the differences in the expropriation provisions of the two agreements.

  • This paper aims to use crossover analysis to uncover similarities and differences between the U.S-Japan relationship in the World War II era and the modern U.S-China relationship, and to forecast the possibility of the outbreak of war between U.S and China by applying the steps to war theory. The steps to war theory argues that the probability of the outbreak of war between two states within five years would approach 90 percent, if they have ongoing territorial dispute, alliance, rivalry, and arms race. The comparison exposes some similarities with the territorial dispute, alliance, rivalry, but reveals dissimilarities with arms race. U.S-Japan relationship in the World War II era had the arms race, which does not exist the modern U.S-China Relationship. The result of comparison is that the probability for the Outbreak of War between U.S and China correspond to third stage(Risk Level). it means that the probability for the Outbreak of War between U.S and China is 55%. But, There are four elements(① Perception of Leader ② Mutual dependence of economy ③ Possession of nuclear weapon ④ Ravages of war) that reduce the probability for the Outbreak of War. Considering the four elements, the probability for the Outbreak of War between U.S and China is a slim chance. But the probability for the Outbreak of War between U.S and China is excluded because of territorial dispute, alliance, rivalry. So, This paper suggests three points.(① Developing military options ② Reducing the misconception of intend, ③ Promoting navy exchanges) to prevent of Outbreak of War.

  • The Federal Maritime Commission is issuing new regulations implementing the Administrative dispute Resolution Act. The new regulations expand the Commission's Alternative dispute resolution(“ADR”) services, addressing guidelines and procedures for arbitration and providing for mediation and other ADR services. This rule replaces current subpart U-(Conciliation Service), with a new subpart U-(Alternative Dispute Resolution), that contains a new Commission ADR policy and provisions for various means of ADR. The rule also revises certain other regulations to conform to the Commission's new ADR policy. So, this paper object was to study on the FMC's ADR in U.S. with the emphasis on the final rule analysis.

  • In this paper, 1 will try to examine the aspects of formants, based on the LPC analysis. In this analysis, five Japanese vowels (a, i, u, e, o) will experience two kinds of experiments: vowels in isolated forms, and vowels in carrier sentences. The analysis results of Japanese vowels of the Japanese natives show a peculiar feature that Japanese vowels form respective vowel groups. Each Japanese vowel makes a statistically significant difference. In the Fl analysis of the vowels grouped by the informant's sex, Japanese vowel (a) shows the greatest standard deviation without regard to the informant's sex. In the F2 analysis of Japanese vowels, each vowel has a statistically significant difference. The fact that the male's [u] shows great standard deviation means that there is a great difference of the frontness of the tongue among the Japanese males in articulating [u]. Isolated vowels and carried vowels show statistically little significance between Fl and F2 frequency values. In another contrastive analysis between the isolated vowel group and the carried vowel group, whether a vowel is articulated in isolation or in a sentence appears to have little effect on its formant frequency.

  • In this study, a DeCART/MIG uncertainty quantification (UQ) analysis code system with a multicorrelated cross section stochastic sampling (S.S.) module was established and verified through the UAM (Uncertainty Analysis in Modeling) and the BEAVRS (Benchmark for Evaluation And Validation of Reactor Simulations) benchmark calculations. For the S.S. calculations, a sample of 500 DeCART multigroup cross section sets for two major actinides, i.e., 235U and 238U, were generated by the MIG code and covariance data from the ENDF/B-VII.1 evaluated nuclear data library. In the three pin problems (i.e. TMI-1, PB2, and Koz-6) from the UAM benchmark, the uncertainties in kinf by the DeCART/MIG S.S. calculations agreed very well with the sensitivity and uncertainty (S/U) perturbation results by DeCART/MUSAD and the S/U direct subtraction (S/U-DS) results by the DeCART/MIG. From these results, it was concluded that the multi-group cross section sampling module of the MIG code works correctly and accurately. In the BEAVRS whole benchmark problems, the uncertainties in the control rod bank worth, isothermal temperature coefficient, power distribution, and critical boron concentration due to cross section uncertainties were calculated by the DeCART/MIG code system. Overall, the uncertainties in these design parameters were less than the general design review criteria of a typical pressurized water reactor start-up case. This newly-developed DeCART/MIG UQ analysis code system by the S.S. method can be widely utilized as uncertainty analysis and margin estimation tools for developing and designing new advanced nuclear reactors.

  • This study was designed to understand family economic well-being in Korea and to compare it with that in the U.S.A. The purpose of this study was to investigate the level of rural family life satisfaction in Korea and in the U.S.A. Specific objectives were: 1. To investigate the influence of independent variabels on rural family life satisfaction, 2. To analyze the influence of socioeconomic variables and social-psychological variables on rural family life satisfaction, and 3. To find commonalities and differences between the two countries. The data, collected from 471 Korean rural households and 301 households in two counties of Ilinois, a state in the U.S.A., were analyzed by frequency distribution, pearson's correlation, one-way analysis of variance, Scheffe test, and multiple regression analysis. The results are as follows: 1. The only common tendency is that the feeling of togetherness influences family life satisfaction in the two countries. 2. The social-psychological variables correlated with each other, and these variables considerably influence rural family life satisfaction in both countries. 3. Sex, number of family members, and no talk influence family life satisfaction differently in the two countries.
