Recently the use of concrete post-installed set anchors has been increasing because this constructing method is flexible and easy to attach or fix structural members when we repair, reinforce, or remodel structures. Accordingly, designers and builders of Korea depend on foreign design codes since there are no exact domestic anchor design codes that they could credit. The anchor in plain concrete loaded in tensile exhibits various failure modes such as concrete breakout, splitting, steel failure, pull-out and side-face blowout, that depending on the tensile strength of the steel, the strength of concrete, embedment depth, interval, the edge distance and the presence of adjacent anchor. The objective is to investigate the effects of the variations like anchor embedment depth, interval and edge distance on pull-out fracture behavior of post-installed concrete set anchor embedded in plain concrete.

Recently the use of concrete post-installed set anchors has been increasing because this constructing method is flexible and easy to attach or fix structural members when we repair, reinforce, or remodel a concrete structures. Depending on the shear strength of steel, the strength of concrete, edge distance and anchor interval, etc, the anchor loaded in shearing exhibits various failure modes such as steel failure, concrete failure, concrete pryout. In this study, the objective is to investigate the effects of the variations like anchor embedment depth, anchor interval, edge distance and concrete strength on the shear failure behavior of post-installed concrete set anchor embedded in concrete. The results of embedment depth experiments show that concrete strength has much effection on the shallow embedment depth. Steel failure occur to all results of the anchor interval experiments, but concrete is failed when edge distance experiments that less than the embedment depth. Through the comparision of the same parameters experiments results show that as strong as concrete strength are the displacement results are small.

In the Western civilization, the concept of culture has traditionally the meaning of education or forming the moral humanity. However, this meaning of culture has recently changed since the advent of cultural relativism which lays stress on the cultural diversity. The current meaning of culture lies in the ways of life, whatever they are. It indicates that culture has nothing to do with universal human nature and morality, as the new concept of culture is only based on the historical and contingent life-situations of people in the each special area. Against this current view of culture, this paper contends that culture and humanity(human nature) are closely connected with each other and that every culture is rooted in the universal human nature. So culture could have a great influence on humanity and forming of moral community. This thesis might be justified by Husserl's view on the philosophical culture of the ancient Greece. According to Husserl, the philosophy in the ancient Greece intended to realize the idea of true humanity and to build the moral community. Husserl's interpretation of the philosophical culture is based on his belief that philosophy as an ideal culture transcends the cultural diversity and historical contingency and strives for a universal human community, in which all mankind are harmonized and live well. The philosophical culture would -so Husserl- result in the moral community. Against this conception of the moral cultural community, could man argue that the idea of the moral community be an ideal dream which could not be realized considering the irrational and immoral character of community. However, this argument should be refuted, because it has overlooked the moral and open-minded character of culture with the feeling of solidarity.

It has been widely recognized that there are two varieties of lateral liquid /l/, which are light /l/ (a non-velarized allophone) and dark /l/ (a velarized allophone). However, this categorical view has been challenged in recent studies, both on articulatory and acoustic aspects. The purpose of this study is to investigate whether to consider /l/ velarization as a continuum in American English and provide supporting data. A spontaneous American English speech database called the Buckeye Speech Corpus was used for the material. The formant frequencies of /l/ in each syllable position were measured and analyzed statistically. The formant frequencies of /l/ in each syllable position, especially F2 values, were significantly different from each other. The results showed that there were other significantly different varieties of /l/ in American English, which support the continuum view on /l/ velarization. Regarding the effect of the adjacent vowel, the backness of the adjacent vowels was shown to affect the degree of /l/ velarization, regardless of the syllable position of the lateral liquid. This result will help provide a solid ground for the continuum view.

Recently, there has been a growing interest in expanded sidewalks for existing bridges. The cantilever beam system applied to expanded sidewalks for existing bridges are connected with the concrete structure by adhesive anchor bolts. However, the extended sidewalks are currently constructed without standardized regulations, which lead to excessive design of the beam spacing and installation and the construction difficulties due to the excessive over-weight. Moreover, there is only limited analysis and experiment data on the post-installed adhesive anchor bolts, so the excessive number of bolts is used for the connection. This paper deals with a method to increase the effectiveness of beam sections and anchor bolts geometry for expanded sidewalk of existing bridge. The study results showed that the failure of cantilever beam connected by adhesive anchor bolts was dominated by bond failure of interface between concrete and bolt. Also, the results indicated the possibilities of improving serviceability as well as safety of the sidewalks by changing of beam section and prestressing the bolts.

Post-installed concrete set anchors are installed after the concrete hardened. These anchors increasing usage in development of construction equipment and flexible construction. The anchor loaded in shearing exhibits various failure modes such as steel failure, concrete failure, concrete pryout, depending on the shear strength of steel, the strength of concrete, edge distance and anchor interval, etc,. In this study, the objective is to investigate the effects of the variations like anchor embedment depth, edge distance and concrete strength on experimental and finite element analysis of shear failure behavior of post-installed concrete set anchor for light load embedded in concrete. The results of embedment depth experiments show that concrete strength has much affection on the shallow embedment depth. Concrete strength has no much affection with anchor interval and edge distance parameter and both experimental results occurred same failure mode. By comparing the experimental results that occurred steel failure mode show that as strong as concrete strength are the displacement results are small.

In general, most of the electrical equipment responsible for control within power plants is housed in self-standing cabinets. These cabinets are typically fixed to a slab using post-installed anchors. Although the fixation method of using post-installed anchors provides stability, there is a risk of conductor failure due to external forces, including moments. However, the performance assessment of current anchors is only evaluated through uniaxial material tests. Therefore, the primary purpose of this study is to compare the static performance of post-installed anchors, considering on-site installation conditions, with their performance in material tests and to analyze the behavioral characteristics of the anchors. While conducting experiments using actual cabinets would be ideal, practical and spatial constraints make this approach difficult. As an alternative, experiments were conducted using a test specimen consisting of a steel column and a support. As a result, the pull-out performance of anchors reflecting on-site installation conditions was measured to be about 10% higher than that observed in material tests. The trends in load reduction and the point of maximum performance for the anchors also differed. To verify the reliability of the experimental study, a 3D FEM analysis was performed, which will provide predictive information on the loads transferred to the post-installed anchors for structural performance evaluations of electrical cabinets using shaking table test in the future.

This study is based on differences of syllable type between Korean and Chinese language pronunciation. For example, Nasal consonant ending 【n】 and 【${\eta}$】 reside in both Korean and Chinese phonetics simultaneously. However, in experiential training, Chinese learners will make errors in pronunciation of the Korean syllable nasal consonant ending like 【n】 and 【${\eta}$】. In the previous research, analysis of pronunciation errors were often based on the perspective of phonological system and combination of the phoneme rules. However, in this study, the analysis is based on the differences between Korean and Chinese syllables category to indicate the cause of pronunciation errors. The main findings of this study indicated that in the process of pronunciation of Chinese, nasal consonant syllable rime and its 【back】 tongue vowel are combined with each other. However, this rule does not apply in Korean pronunciation. Therefore, the Korean syllabic types like "앤, 응, 옹, 앵, 은, 온, 언" also exist in the Chinese language. When theChinese learners pronounce these types of syllables, the combination of the voweland nasal syllable rime rule will be taken, which will result in pronunciationerrors.

In this paper I will investigate the problems of the Ego of Kant, Husserl and $Yog{\bar{a}}c{\bar{a}}ra$ from the standpoint of $trisvabh{\bar{a}}va$ and the transformation of the basis of $Yog{\bar{a}}c{\bar{a}}ra$. Kant's Copernican revolution and Husserl's Phenomenological reduction are the keys to understanding their philosophies. We especially want to look into the comparison between the Ego of Kant, Husserl and $Yog{\bar{a}}c{\bar{a}}ra$. According to Kant, we need the transcendental Ego as absolute in order to unite consciousness. Kant criticizes traditional metaphysics which had argued that the metaphysicians regard the transcendental Ego as substance. If they regard the transcendental Ego as an empirical object, this attempt will be in vain, because they seek to know unknown things. Husserl's phenomenological reduction is properly understood as a method designed to transform a philosopher into a phenomenologist by virtue of the attainment of a certain perspective on the world phenomenon. We will find the field of the transcendental, absolute ego through phenomenological reduction. Transcendental, absolute ego constitutes our whole world and gives meaning to the world. $Yog{\bar{a}}c{\bar{a}}ra$ argues that what our ordinary consciousness (the sixth consciousness) regards subjectivity and objectivity as separate, or that self and the world is an imagination that $alaya-vij{\tilde{n}}ana$, the mind more profound than the ordinary consciousness, created. $Yog{\bar{a}}c{\bar{a}}ra^{\prime}s$ $alaya-vij{\tilde{n}}ana$ creates the whole objects and the consciousness (the sixth), so we must regard them as illusionary. $Yog{\bar{a}}c{\bar{a}}ra$ insists that there are three natures of mind and we attain the transformation of the basis in mind. Based on this point of view, Kant, Husserl and $Yog{\bar{a}}c{\bar{a}}ra$ want to transcend and overcome the limits of the ordinary consciousness, and then they want to find the absolute truth (everything) and want to be a men of freedom.
