In this paper, we present a magnetic levitation system which has not a gap sensor with sensor-less realization and stabilizing controller design. For measuring gap between magnet and levitated object we propose a gap sensorless method and adop two-degree-of-freedom controller for robust-ness and performence of the magnetic levitation system. From time responeses we confirm that the proposed sensorless method which can be applied to magnetic levitation system. Also the designed stabilizing controller has good disturbance rejection and reference tracking performance.

This paper investigates previous theories on English focus realization and attempts to find out the overall acoustic characteristics of English focus. It has been argued in previous studies that English focus can be defined as a new information that is not recoverable from the context (Halliday 1967), a complementary element of presupposition (Jackendoff 1972), and what is predicated about the topic in a sentence (Sgall 1973, Gundel 1974). The phonetic realization of English focus in an utterance has been said to be either L+H*/H*, or falling accent. Yet it is a more or less simplified pattern not based on real data obtained from native speakers of English, and it does not consider the various pragmatic and contextual situations. In our experiments we found that native speakers uttered English focus sentences in different ways according to the different focus structure. Another notable result is that Korean speakers, when provided with the same experimental material, are neither able to distinguish different focus types nor deaccent the elements that are not focused in an utterance.

This paper discusses a distributed implementation of the Biba security policy model. Implementation of an service in the OSI-RM is not sufficient for enforcing the Biba model. Also confidentiality services are necessary. Public Key Systems(PKSs) are considered for the realization of these security services. In this paper symmetric & asymmetric cryptographic systems are considered for the realization of these security service. It is investigated how key-distributions can be found resulting in a minimum number of key.

This study focuses on the asymmetrical realization of homorganic nasal-obstruent stop clusters in English when they occur word medially and word finally. This uneven realization of NC clusters is not only controlled by the place of articulation of the cluster constituents but also by the agreement of voicing feature specifications of the cluster elements. We propose context-sensitive constraints, which are more specified versions than *NC (Pater, 1996, 1999, 2004). The result of the study reveals that homorganic NC clusters consisting of coronal place feature are faithfully realized word finally while they are constrained word medially. The deletion of voiceless post-nasal coronal stop should be considered a new language specific strategy to avoid *NC.

In this paper we propose various rotation block realization method of MIMO LBR system. For this, we first discuss how to realize a given LBR system in the form of LBR two-pair cascades. Then we examine several systematic extraction procedures which enable to realize each LBR two-pair in the form of rotation block. Then we consider which realization methods we select for each two-pair block in view of the dynamci range of the coefficients of the rotation blocks. Finally, we demonstrate the LBR realization method using a detailed numerical example that converts a 4th order IIR filter function into a 4*4 transform domain transfer matrix, and then realizes it in a rotation-block cascade.

The aim of this paper is to analyze the phonetic features of the lexical contrastive focus and the segmental contrastive focus. In this paper, I made two variables to study the realization of the contrastive focus. One is the three phonation types of the Korean plosive, a lenis, a fortis and an aspirate. The other is the positions of the segmental contrastive focus syllable in a word. I examined pitch, duration, intensity, VOT, formant, and so on. The realization of focus is different by the phonation types and the positions of the focused syllable.

The purpose of this paper is to research the realization of /h/ between sonorant sounds. For this purpose, we analyze speech of 5 people using standard Korean. As a result, we can find that the possibility of deletion of /h/ is increasing, when speech rate is high, the AP has more syllables, and /h/ is far from the AP-initial. While the position of AP or IP has no relation to realization of /h/. The deletion of /h/ is more often in this order. Followed segments: lateral>nasal>vowel, following segments: vowel>glide. And there is no change on duration of following vowel after /h/ deletion.

In this paper we discuss the Socratic method from the aspects of subject education and examine the meaning of the method in mathematics education that is the most suitable subject for the realization of the Socratic method. In addition, as a realization of the Socratic method, we conducted a teaching-learning experiment of complex natural exponential function with a 2nd year college student. The results of the experiment are analyzed with the intention of improving instruction of the complex analysis that is one of the college mathematics courses.

In this present article, we construct a new framework that's we call the weighted geometric realization of 2 and 3-simplexes. On this new weighted framework, we construct a nonself-adjoint 2-simplex Laplacian L and a self-adjoint 2-simplex Laplacian N. We propose general conditions to ensure sectoriality for our new nonself-adjoint 2-simplex Laplacian L. We show the relation between the essential spectra of L and N. Finally, we prove the absence of the essential spectrum for our 2-simplex Laplacians L and N.

The aim of this research was to examine the traditional Confucian view of self-realization in East Asia and the meaning of life implied therein. The researcher closely reviewed the phase of self-realization of both Confucius and Mencius who are central in Confucianism, especially in the primordial Confucianism, and after investigating maturity of personality as well as educational characteristics thereof, the researcher tried to elicit its modern significance. In Analects, Confucius who is the founder of Confucianism mentioned about 'the pleasure of studying and practicing what he has learned'(學而時習 "Hagisiseup" in Korean), since after, his past was then just the process of self-realization that lasted throughout life. That is, the six phases of self-realization, to wit, 'bending on learning(志學, "Jihak")-'standing firm'(而立, "Irip")-'having no doubts'(不惑, "Bulhok")-'knowing the decrees of Heaven'(知天命, "Jicheonmyeong")-'ear being obedient organ for the reception of truth' (耳順, "Isun")-'able to follow what my heart desires without transgressing what is right'(從心, "Jongsim"), are lying hidden and undeveloped during lifetime, and, at the same time, these phases illustrate the state of enlightenment of life in an in-depth manner. By showing the process of living which is being sublimated in respect of quality, and by going through important process of self-innovation up to six times during lifetime, Confucius edifies us the activity of complete self-realization as well as the importance of education and learning. Meanwhile, these are connected to Mencius in a similar pattern, and strong influence of the characteristics of the learning of the mind and heart( 心學, "Simhak") based on his philosophy permeates the self-actualization phase of Mencius. Mencius' self-actualization phase is expressed in terms of six stages, viz., Person of Goodness(善人, "Seonin")-Trustworthy Person(信人, "Sinin")-Person of Beauty(美人, "Miin")-Great Person(大人, "Daein")-Sage(聖人, "Seongin")-Divine Person(神人, "Sinin"), and these six phases of self-actualization process are educational and learning model for people who dream actualization of perfect personality during their lifetime. Confucian and Mencian view of self-realization congruent with self-discipline internally, and it also reveals a stereotype of human externally. These are a process of performing organic ideals in order for cultivating oneself and regulating others(修己治人, pronounced 'sugichiin' in Korean) which has been pursued by Confucianism. Briefly, these self-realization phases are the arts of living that will lay foundation for "Being Born Human, pronounced Saramim' in Korean" and for becoming "Fully Human, 'Sarmadoem'" and finally for "Human Feelingness, 'Saramdaum'
