We partially characterize criteria for the n-universality of positive-definite integer-matrix quadratic forms. We then obtain the uniqueness of Oh's 8-universality criterion [11] as a corollary.

This paper aims to contrast phonology of Korean and Thai in terms of language universality. Considering consonants, both languages having 21 typologically most plausible consonants display high universality in the number of consonants. However, Thai shows higher universality in regards to their substance, i.e. it differs from Korean when it comes to the structure of plosives and fricatives. Both Korean and Thai show similarities regarding the plosives due to the fact that both languages possess three contrastive consonants. However, the Thai plosives consist of plain voiced, plain voiceless and aspirated voiceless sounds that have higher universality than the Korean plosives which are plain voiced, plain voiceless and aspirated voiceless. In case of vowels, both Korean with its 10 vowels and Thai with its 9 vowels show lower universality when it comes to the total number of vowels. However, all of those vowels belong to the list of most plausible vowels which makes their universality higher in substance. In respect of syllable structure, Korean with its CVC type shows a moderately complex structure while Thai with its CCVC type has a complex structure. The coda may consist of only one consonant in each language but onset is composed of one consonant in Korean, and two consonants in Thai. The contrastive study of similarities and differences between Korean and Thai in terms of phonology will help not only understand the two languages but also provide useful information for increasing the efficacy of Korean language education for Thai learners of Korean whose number is rapidly increasing.

This study aims to contrast phonological characteristics of Korean and Turkish in terms of language universality. Considering consonants, both languages have the same number of consonants (21), which is the most typologically plausible structure of consonants. Thus, it can be said that they display high universality in the number of consonants. However, Turkish shows higher universality in regards to their substance, i.e., it differs from Korean when it comes to the structure of plosives and affricates. Turkish has two contrastive consonants, i.e., voiced and voiceless. However, the Korean plosives and affricates consist of neutral, tense and aspirate voiceless. In the case of vowels, both Korean with 10 vowels and Turkish with 8 vowels show lower universality. Yet, all of those vowels belong to the list of the most plausible vowels which makes their universality higher in substance. In respect of the syllable structure, Korean with its (C)V(C) type shows a moderately complex structure while Turkish with its (C)V(C)(C) type has a complex structure. The coda may consist of two consonants in Turkish while only one consonant is possible in Korean. However, onset is composed of one consonant in both languages. The contrastive study of similarities and differences between Korean and Turkish in terms of phonological characteristics will help not only understand the two languages but also provide useful information to increase the efficacy of Korean language education for Turkish learners of Korean, whose number is rapidly increasing.

In the world, the old population is growing fast and many countries went into an advanced age society. Therefore the development of everyday products, electric appliances, and welfare services considering old people is more important than ever. In particular, the complexity of products can cause many problems for old people. Universal design is an approach to create environments and products that recognizes the diversity of users, regardless of their ability or age. Universality evaluation for a product is very important to verify old people's accessibility and usability for the product. Universality means how good a product was designed in view of universal design principles. In this study, UNIX, a method to evaluate the universality of a product was developed. UNIX was based on seven universal design principles; equitable use, flexibility in use, simple and intuitive, perceptible information, tolerance for error, low physical effort, size and space for approach and use. UNIX is a kind of expert evaluation and very simple method. The method is consisted of two steps. In the first step, relative weights for seven principles and subjective ratings on design suitability for each principle are obtained. In the second step, universality index (UNIX) of each product is obtained by weighted average multiplying relative weights and rating scores. As a case study, this method was applied for mouse designs. In conclusion, this method could be effectively applied to evaluate the universality of a product.

This paper delves into the question of universality in Native American Literature focusing on Leslie Marmon Silko's Ceremony, exploring some different definitions of universality and looking at the work in the light of these definitions. In this paper I proposed four possible definitions or faces of universality applicable to the narrative of the oppressed people. Firstly, the colonizers indoctrinate their colonized persons with the colonialists' beliefs through the process of assimilation purposefully imposed in the name of universality. In Ceremony Rocky and Emo are the victims of assimilation including militarization. Secondly, the colonized people hold on to their traditional values in face of colonizers' universalism. In Ceremony Tayo shows an attachment to tribal stories in opposition to whites' lies. Thirdly, the colonized can get together by sharing experiences of violence, occupation, and loss of their land and language, forming a bond of "commonality" among them. In Ceremony the story of a medicine man, Betonie, suggests oneness of victims against the evil power of destroyers represented by nuclear bombs. Fourthly and lastly, the universal consists in the subject's trial and practice attempting to achieve universalism against the existing order, not in the stipulation defining what is universal. In the story Tayo endeavors to retrieve his cattle by transgressing whites' property and makes a hole in the established dichotomy of whites and Indians. In sum, Ceremony as a minor literature shows the developmental aspects of universality, culminating in Tayo's refusal to assimilate himself to whites' lies.

In [9], Lee and Sakuma constructed 2-generator non-Hopfian groups each of which has a specific presentation ${\langle}a,b{\mid}R{\rangle}$ satisfying small cancellation conditions C(4) and T(4). In this paper, we prove the SQ-universality of those non-Hopfian groups.

The expansion of two different kinds of hydrodynamic size of polymethyl methacrylate (PMMA Mw: 1.56- 2.04 ${\times}$ 106 g/mol) has been measured by dynamic light scattering and viscometry above the Flory $\theta$ temperature of the variou s solvents such as n-butyl chloride, 3-heptanone, and 4-heptanone. The expansion of PMMA chains was analyzed in terms of universal temperature parameters and also compared with previous results of polystyrene (PS) system. First it was found that simple $\tau/{\tau}c$ parameter no longer had its universality for the expansion behavior of hydrodynamic size in the chemically different linear polymer chains. However after modifying ${\tau}/{\tau}c$ parameter into $(Mw/Ro2)3}2(\tau/\tauc)$, we observed a much better universality for both PMMA and PS systems. Here Mw, Ro, $\tau[=(T-{\theta}$)/${\theta}$]$, and ${\tau}c[=({\theta}-Tc)/Tc]$ are defined as the weight average molecular weight, the unperturbed end-to-end distance, the reduced temperature and the reduced critical temperature, respectively.

The purpose of this study is to develop a new domestic (national) law classification scheme with universality. An underlying reason for the development of this scheme reset upon the fact that Civil law system, Common law system, Socialistic law system have had difficulties each other and that current classification scheme covering three law systems have not been still in existence. From the comparative discussion of classification schemes that are the representative of each law system, a new national law classification scheme with universality was designed. If law classification scheme have been completeness, this new scheme must be combined with jurisprudence and international law classification scheme which was developed already.
