According to the thesis of the publicity of reasons, practical reasons are public in their nature: the normative force of reasons may extend across different agents. Wallace argues that the normative mode of public reasons can be exhausted by what he calls the requirement of non-interference. I argue that the publicity thesis as he presents it equally applies to both (non-special) interpersonal relations and special relationships. At first, Wallace's version of the publicity thesis may seem incompatible with the fact that there exists reasons of positive aid. He says that when these reasons obtain in the case of interpersonal relations, they are accommodated by relevant specific moral principles. I defend this claim by showing that there is a kind of internal relation between the publicity thesis and moral principles in question. It is true that the reasons of positive aid obtain in the case of special relationships as well. I show that in this case such reasons are grounded by the requirements of the given special relationships themselves. I argue that the logical consequence of these claims is what I call the dualistic conception of our practical reasoning about what to do and that this dualism does not raise a serious challenge to the publicity thesis. The overall arguments of this paper, I believe, make us to be "realistic" about the philosophical significance of the thesis in question in moral discourses.

With the expansion of floating-point operation requirements for fast high-speed data signal processing and logic operations, the speed of the floating-point operation unit is the key to affect system operation. This paper studies the performance characteristics of different floating-point multiplier schemes, completes partial product compression in the form of carry and sum, and then uses a carry look-ahead adder to obtain the result. Intel Quartus II CAD tool is used for describing Verilog HDL and evaluating performance results of the floating point multipliers. Floating point multipliers are analyzed and compared based on area, speed, and power consumption. The FMAX of modified Booth encoding with Wallace tree is 33.96 Mhz, which is 2.04 times faster than the booth encoding, 1.62 times faster than the modified booth encoding, 1.04 times faster than the booth encoding with wallace tree. Furthermore, compared to modified booth encoding, the area of modified booth encoding with wallace tree is reduced by 24.88%, and power consumption of that is reduced by 2.5%.

We can witness the recent surge of interest in the controversy over the scientific status of mathematics among Jesuit Aristotelians around 1600. Following the lead of Wallace, Dear, and Mancosu, I propose to look into this controversy in more detail. For this purpose, I shall focus on Biancani's discussion of scientiae mediae in his dissertation on the nature of mathematics. From Dear's and Wallace's discussions, we can gather a relatively nice overview of the debate between those who championed the scientific status of mathematics and those who denied it. But it is one thing to fathom the general motivation of the disputation, quite another to appreciate the subtleties of dialectical strategies and tactics involved in it. It is exactly at this stage when we have to face some difficulties in understanding the point of Biancani's views on scientiae mediae. Though silent on the problem of scientiae mediae, Mancosu's discussions of the Jesuit Aristotelians' views on potissima demonstrations, mathematical explanations, and the problem of cause are of utmost importance in this regard, both historically and philosophically. I will carefully examine and criticize some of Mancosu's interpretations of Piccolomini's and Biancani's views in order to approach more closely what was really at stake in the controversy.

Now, Korea-U.S.A Free Trade Agreement talk is underway in Korea. In FTA talks, the issues on audio-visual sector including screen quota, opening of broadcasting and telecommunication to the U.S.A. are becoming a hot potato. Globalization has been speed up by mass media and telecommunications. Cultures are no longer bounded by specific place but, through the migration of persons and the electronic flows of information, ideas and images, transgress established boundaries. So issues and debates have to be focused on global culture and cultural imperialism. Some would argue global culture is the consequences of capitalist world-system, so dominance by the center should be criticized and vanished. Some would say that global culture would help recipient society's people with cultural diversify and improvement. The issues on culture and communication, particularly at international level call for our attention in light of cultural identity, homogenization and diversity. Although I criticize the cultural imperialism thesis, I suggest critical acceptance of cultural imperialism. That is the observation of complexity between internal and external dynamics. The process of cultural imperialism is not simple and unitary. It rather involves the various forces of internal dynamics along with external forces.
