  • In their recent paper published in this journal Shin Kim and Jinyong Lee have attacked some previous studies on the counterexample to modus ponens. Among their arguments I would like to discuss the following two; first, those attempts to explain van McGee's example by reference to conditional probability do not accord with van McGee's position, second, van McGee'e example is to be best seen as an argument containing the fallacy of equivocation. I show that the first argument is not correct, the second one is not so persuasive as it seemed first.

  • The general wiretap channel with noiseless feedback is first investigated by Ahlswede and Cai, where lower and upper bounds on the secrecy capacity are provided in their work. The upper bound is met with equality only in some special cases. In this paper, we study a special case of the general wiretap channel with noiseless feedback (called non-degraded wiretap channel with noiseless feedback). Inner and outer bounds on the capacity-equivocation region of this special model are provided. The outer bound is achievable if the main channel is more capable than the wiretap channel. The inner bound is constructed especially for the case that the wiretap channel is more capable than the main channel. The results of this paper are further explained via binary and Gaussian examples. Compared with the capacity results for the non-degraded wiretap channel, we find that the security is enhanced by using the noiseless feedback.

  • This paper proposes a paradigm for research on broadcast political interviews. Developed using a series of studies, the paradigm introduces core aspects and questions that should be addressed when examining political interviews in a particular society. This paradigm will enable researchers to collect detailed accounts of the interaction between interviewers and interviewees, the structure and tone of the questions posed to interviewees and the interviewees' communicative style when addressing such questions, and the strategies employed by the participants to pursue their goals. It is hoped that the paradigm will encourage the interest and facilitate the study of televised political interviews particularly from the nationally, culturally, and socially diversified Asian countries. Gathering detailed data from non-Western societies in Asia will also facilitate our understanding of the function and effect of political communication from a cross-cultural perspective.

  • This paper is an attempt at developing a method for the analysis and estimation of the effects of project disruptions due to uncertainties. Such uncertainties may result from design changes in large-scale, complex, research and development, or construction projects. An entropical risk analysis method is developed. The method is able to estimate the project capacity to handle equivocation due to design changes and the effects of project disruptions. In an attempt to evaluate the predictive capability of the method, it is compared with the results obtained by a computer Monte Carlo simulation program. It is shown that the entropical risk analysis method may be suggested as an expedient means of evaluating project status for management in the different stages of project execution.

  • This study is concerned with some methods and applications, used as a basis on information and entropy analysis of vegetation data. These methods are adopted for the evaluating the effect of sampling intensity on information, which repersnets the departure of observed variable from standard component. Classes on the data matrix are caluculated by using marginal dispersion array for rank and weighting information program. Finally the information and entropy are computed by applying seven options. On the application of vegetation studies, two models for cluster analysis and analysis of concentration are explained in detail. Cluster analysis is based on use of equivocation information and Rajski's metrics. The analysis of concentration utilizes coherence coefficience being transformed values, which has been adjusted from blocks and entropy values. The relationship btween three begetation clusters and four stands of Naejangsan data is highly significant in 79% of total variance. Cluster A relatively tends to prefer north side, and cluster C south side.

  • Vann Mcgee produced "counterexamples" to Modus Ponens in "A Counterexample to Modus Ponens". Discussions about the examples tended to focus on a probabilistic reading of conditional statements. This article attempts to establish both (1) Modus Ponens is a deductively valid rule of inference, and (2) the counterexample-like appearance of Mcgee's example can be (and should be) explained without making a reference to the notion of conditional probability. The reason why his examples seem to counter Modus Ponens is found rather within the ambiguity a conditional statement exhibits. That is, Mcgee's examples are cases of equivocation on the conditional statements involved.

A Study on the Standardization of Interface Terms for Information Retrieval (웹기반 정보검색시스템의 검색관련 용어 표준에 관한 연구)

  • This research suggests the method of standardizing terms for raising the effectiveness of information retrieval. Especially for web search, I propose the proper terms which they will use in retrieval by surveying and analysing the related terms about information retrieval interface. The proper terms will solve the equivocation for user increase the effectiveness. And I think the proposed terms will be used to standard data for designers who are construct the user interface systems.

  • Launched by Samsung in 2003, nano-silver washing machines were a representative application of nanotechnology in commercial products until the US Environment Protection Agency (EPA) decided to regulate companies that produce nano-silver products in 2006. A year later, however, the EPA reclassified the washing machines not as an application of nanotechnology but as an ion-generating machine. As shown by the EPA's equivocation on this issue, establishing a category for nano-silver material should be considered in the procedure of risk assessment and regulation. This paper analyzes the controversy over Samsung's nano-silver washing machines more in detail to study how the demarcation between silver ion and nano-silver can vary according to the risk perception of nanotechnology. In Korea and the US, the boundary between silver ion and nano-silver was malleable and mobilzed depending on the contexts. Based on an analysis of the recent history of nano-silver washing machines, this paper explores the influence of risk perception over the ontological perspectives on a certain material.

  • The Chilean educative policies as the Voucher System and the privatization have been almost same from the Pinochet government and the ones of "Concertacion" or "Democratic Alliances" until now. Because the neoliberal regime has dominated principally in Chile the area of the education. In this study first of all I will analyze the procedures of the violent repression of the leftist politicians and the intellectuals of the universities by the Pinochet government. And the importance of the reform of the law of education in 1980 was emphasized and the other one in 1990 one day before the retirement of Pinochet. We can comprehend the fact that the education would have been used as a tool to achieve the development of the country and the economic one sacrificing the public and equalitarian values of the education. And the competence, the efficiency and the quality of the education have been emphasized through the policies as example the rights of the selection of the schools by the parents as like a product in the market. But the result was the enormorors expansion of the private education not only in the secondary schools but also in the universities. And also has been intensified "the segregation and the discrimination" of the students jerarquitized by the different social-economic levels of the parents. The Chilean people including the middle class did not realize rightly the inherent problems of the neoliberal regime having the equivocation as if the private schools should have been better than the public ones. However the high level of the public university education became to be dominated by the acomodated class. This was the cause of the last year's great scale of the demonstration of the Chilean students. The most important thing is that these matters was agravated not by the Pinochet government but by the ones of "Concertacion" or "Democratic Alliances". Because these governments tried to maintain the neoliberal regime by means of the education only arranging the small problems or contratiempos.
