The main objective of this paper is to vindicate the Bayesian belief updating rule, i.e. conditionalization. For this purpose, I introduce first what I call Irrelevance Principle, and show that this principle is equivalent to conditionalization. In turn, the principle is vindicated by means of Bayesian confirmation theory. That is, I suggest some theses that Bayesian confirmation theorists should accept, and prove that if Irrelevance Principle is violated, the theses cannot holds.

This paper examines the way that the principles of coloration for Hoecha(繪次) and Sucha(繡次) were applied for shoe making in ancient China and Korea. Hoecha is the principle of drawing, and Sucha is the principle of embroidery. Hoecha and Sucha is the application principle of the five colors(五方色) from the five elements(五行: metal, wood, water, fire, and earth). Hoecha matchs a color with the opposite side color, and Sucha matchs a color with the beside color. A shoe consists of Sinul(body of shoe) and ornaments attached to it. According to the ratings of shoes, Hoecha and Sucha were differently applied for coloration of Sinul and its ornaments. In general, shoes were classified into Seok and Gu. For Seok, which was the high-ranked shoes, Hoecha was applied, while Sucha was applied to Gu, the low ranked shoe. As Hoecha was originally a principle of coloration for patterns on tops(jacket. 上衣), it was applied to the high ranked shoes i.e., Seok. Also, as Sucha was a principle of coloration for patterns on bottoms(skirt. 下裳), it was applied to the low ranked shoes i.e., Gu. Thus, black was decorated on red Seok, blue on white Seok, red on black Seok, yellow on hyeon(玄: a kind of black color) Seok, and white on blue Seok, all of which were applications of the principle of Hoecha. As the application of the principle of Hoecha to Seok was also done for red Seok for males and females in late Joseon, and red Seok for the crown prince in the period of the Korean Empire, black decorations were used for red Sinul. However, for blue Seok, worn by females in the period of the Korean Empire where Ming's systems prevailed, black decorations were used, which was an application of Sucha. Though there had been no discrimination between genders in the application of Hoecha and Sucha originally, the low ranked principle of coloration was applied to Seok for females.

This paper considers a classification of the 88 islands located at Kyong-nam area in Korea, using by examples of 12 components of the islands. By means of principal component analysis 2 principle components were extracted, which explained a total of 73.7% of the variance. Using an eigen variable criterion (λ>1), no further principle components were discussed. Principal component 1 and 2 explained 63.4% and 10.3% of the total variance respectively, The representation of the unrelated factor scores along the first and second principal axes produced a new information with respect to the classification of the islands. Based upon the representation, 88 islands were classified into 6 groups i. e. A, B, C, D, E, and F according to similarity of the components among them in this paper. The "Group F" belongs to a miscellaneous assortment that does not fit into the logical category. category.

The dielectric properties of two polyurethanes (PUs) with different hard segments, i.e., aromatic methylene di-p-phenyl diisocyanate (MDI) and aliphatic hexamethylene diisocyanate (HDI), were investigated in the temperature range of -100 to $100^{\circ}C$ and in the frequency range of 1 Hz to 3 kHz. The ${\alpha}$-relaxations induced by the glass transition of the equivalent soft segments in the two PUs occurred at relaxation times of ${\tau}=3.46{\times}10^{-3}s$ for MDI-PU and ${\tau}=3.39{\times}10^{-2}s$ for HDI-PU at $-20^{\circ}C$, in accord with the temperature-frequency superposition principle, resulting in similar shifting factors. However, different I-relaxations were observed for the two PUs. The I-relaxation of MDI-PU occurred due to the mobility of the chain extenders near $80^{\circ}C$ with a slower shifting rate than the ${\alpha}$-relaxation. On the other hand, I-relaxation arising from both the extender and the unconstrained hard segments of HDI-PU occurred at $70{\sim}100^{\circ}C$, indicating complicated dielectric behavior due to partial interaction with the ${\alpha}$-relaxation at high frequencies. Thus, the I-relaxation of HDI-PU did not follow the superposition principle. The dielectric behaviors of the PUs were mainly influenced by their phase transitions, which were affected by the structure and components of the materials.

A number of previous researches in evolutionary algorithm are based on the study of facets we observe in natural evolution. The individuals of species in natural evolution occupy their own niche that is a subdivision of the habitat. This means that two species with the similar requirements cannot live together in the same niche. This is known as the competitive exclusion principle, i.e., complete competitors cannot coexist. In this paper, a new evolutionary programming algorithm adopting this concept is presented. Similarly in the case of natural evolution , the algorithm Includes the concept of niche obtained by partitioning a search space and the competitive exclusion principle performed by migrating individuals. Cell partition and individual migration strategies are used to preserve search diversity as well as to speed up convergence of an ...

Phase transformation is used to change some phase from phase in A.C. system. We have been used Scott or Fork connection in phase transformation the otherwise phase transformation was constructed from M-G set. From this M-G set, we could make phase shift facilities by mannual. Now, I can derive more easy phase transformation from taking another method. I believe this new phase transformation method in the first thing in the world. And so, I am going to explain about phase transformer construction process. The first, we could devide into equal part of core around the iron core as to be same size. The second, you will make primary and secondary winding on the core. The third, when you will supplied three phase A.C. at the terminal of primary winding you can get e.m.f. inducing of some phase at secondary. And so, we could make phase change from some phase A.C. We can apply this principle in many fields, i.e., freequency changer, phase leader of no use condenser, voltage regulator in keeping balance, and D.C. generator. And more, I will introduce in details concerning main pinciple and theory through following chapter.

The March 2022 presidential election held at the peak of the COVID-19 pandemic drew flak for undermining the principle of universal suffrage by failing to guarantee properly the voting rights of confirmed and quarantined persons. Guaranteeing their voting rights requires thinking about e-voting that can fundamentally overcome the temporal and spatial limitations of current paper voting polling stations. The question is how to deal with the increased possibility of contradicting or violating the principles of equality and direct and secret suffrage due to the expansion of universal suffrage. In order to obtain implications for this, we looked at the case of Estonia, which has been holding 11 national elections without any problems since the introduction of e-voting in 2005. Estonia was successfully building trust in the system, government, and society through the institutionalization and routinization of the overall socio-technical system of e-voting, along with political and constitutional agreements on the principles of elections. Therefore, we should not only consider the possibility of e-voting in terms of technological development and level but also discuss the establishment of trust by mediating conflicts between election principles from a normative point of view to reach a social consensus.

In English, whether or not wh-movement creates weak crossover effects depends upon the type of wh-phrases that cross over. A bare interrogative like who shows a typical weak crossover effect whereas which N type (e.g. which girl) and partitive type (e.g. which of these girls) wh-phrases would show mere weaker and weakest crossover effects, respectively. Previous approaches to English crossover phenomena that resort to a binary notion of specificity or D-linking cannot account for the three-way contrast the three different types of wh-phrases show. To overcome this problem, I argue in this paper that specificity should be a non-binary set-theoretic notion and propose the following subset principle and optimal binding relation: Between two lexical nominal expressions A and B, A is regarded as more specific than B iff the denotation of A comes from a more narrowly defined non-singleton set than B. Between two lexical nominal expressions A and B, if A locally binds B, then the non-singleton set from which the denotation of A comes should be a subset of the set from which the denotation of B comes (i.e. B cannot be more specific than A). The smaller the subset (i.e. the wider the specificity gap between binder and binder), the more optimal the local binding relation is. A locally binds B iff A is coindexed with B, and A c-commands B, and there is no such C that does not bind A but binds B. Finally, I show that partitivity functions to carve out a smaller subset and thus make partitive wh-phrases more specific than simple which N type wh-phrases.

An analytical approach for the free vibration behavior of a sandwich cylindrical shell with a functionally graded (FG) core is presented. It is considered that the FG distribution is in the direction of thickness. The material properties are temperature-dependent. The sandwich cylindrical shell with a FG core is considered with two cases. In the first model, i.e., Ceramic-FGM-Metal (CFM), the interior layer of the cylindrical shell is rich metal while the exterior layer is rich ceramic and the FG material is located between two layers and for the second model i.e., Metal-FGM-Ceramic (MFC), the material distribution is in reverse order. This study develops Carrera's Unified Formulation (CUF) to analyze sandwich cylindrical shell with an FG core for the first time. Considering the Principle of Virtual Displacements (PVDs) according to the CUF, the dependent boundary conditions and governing equations are obtained. The coupled governing equations are derived using Galerkin's method. In order to validate the present results, comparisons are made with the available solutions in the previous researches. The effects of different geometrical and material parameters on the free vibration behavior of a sandwich cylindrical shell with an FG core are examined.

Based on the articulatory phonetic (or organic) principle, the Korean alphabet of 28 letters as invented by King Sejong in 1443 is not only systematic and scientifically oriented but also easy to learn and use in everyday life of the Korean people. The International Korean Phonetic Alphabet was devised by the present writer in 1971 by applying the organic principle much more extensively. Accordingly, the IKPA symbols are just as simple and easy to loam and memorize as the Korean alphabet, and at the same time they are much more consistent and logical than the IPA symbols which, having been derived mainly from Roman and Greek letters, are unsystematic mass of letters except in one respect, i.e., retroflex symbols. This paper describes the organic principles exploited in devising the International Korean Phonetic Alphabet and assesses its advantages.
