The objective of this study was to develop an artificial dentin for easy handle and accurate observation of the mechanism on dental caries and to screen biologically active materials from the extracts of traditional plants and fruits for prevention of early dental cares. In order to produce disc PAHA (artificial dentin), the powdered hydroxylapatite was immobilized in a 20% polyacrylamide gel. The characteristics of disc PAHA was very similar to the surface, figure and lattice of human enamel. After decalcification in 0.1M citric acid based on observation with SEM. The critical point of decalcification of disc PAHA by acids was found to be pH 5.0-5.5, which was hi agreement with human enamel. The degree of decalcification from disc PAHA in 0.1M citric acid solution was sixfold higher than that of human enamel. This result suggested that disc PAHA would be useful as a substitute of human enamel for in vitro experiment. The extracts of garlic and Flower Apple A, B seemed to inhibit growth of S. mutans. Especially, when the 300$\mu\ell$ of its extracts added to the medium to incubate S. mutans, F. apple B showed strongly an inhibitory effect in both the growth of S. mutans and the synthesis of insoluble glucan.

The cold image of digital culture and its realistic limits force modern people to yearn for an emotional world characterized by a warm humanity. The kind of digital technology that appeals to such a human emotion is accepted as a new digital concept in the 21st century. The purpose of this study was to examine the characteristics of emotionality, which was a new trend in digital culture, and to discuss its form and meaning in fashion sector. It's basically meant to figure out a major trend in the 21st century's digital culture, to delve into its relationship with fashion reflecting sociocultural phenomena, and ultimately to describe in which direction future fashion would be led. Emotionality was highlighted as a reaction against an absolute pursuit of speed and cold digital technology. Emotionality of digital culture in fashion design were inserting of funology, Zen-based design and development of a clothing mixture. The emphasis of emotionality in digital culture is a new sociocultural trend that stresses the recovery of human nature. As futurologists predict that a human-centered and humanistic culture will reappear in the 21st century, fashion also will be in pursuit of human-oriented design.

Many other human species appeared in evolution in the last 6 million years that have not been able to survive to modern times and are broadly known as archaic humans, as opposed to the extant modern humans. It has always been considered fascinating to compare the modern human genome with that of archaic humans to identify modern human-specific sequence variants and figure out those that made modern humans different from their predecessors or cousin species. Neanderthals are the latest humans to become extinct, and many factors made them the best representatives of archaic humans. Even though a number of comparisons have been made sporadically between Neanderthals and modern humans, mostly following a candidate gene approach, the major breakthrough took place with the sequencing of the Neanderthal genome. The initial genome-wide comparison, based on the first draft of the Neanderthal genome, has generated some interesting inferences regarding variations in functional elements that are not shared by the two species and the debated admixture question. However, there are certain other genetic elements that were not included or included at a smaller scale in those studies, and they should be compared comprehensively to better understand the molecular make-up of modern humans and their phenotypic characteristics. Besides briefly discussing the important outcomes of the comparative analyses made so far between modern humans and Neanderthals, we propose that future comparative studies may include retrotransposons, pseudogenes, and conserved non-coding regions, all of which might have played significant roles during the evolution of modern humans.

The purpose of this study is the development of an experimental design that aims to implement three-dimensional fashion design by observing the human body, extracting and combining geometric shapes and forms, and focusing on attempts to decompose the geometry of the human body in art history. Considering the characteristics of fashion design, which inevitably reflect human images visually, this study considered works by deriving geometric shapes and forms of the human body and focusing on decomposition and combination to apply them to fashion design. The results obtained through the development of fashion design through decomposition and combination based on geometric human body analysis are as follows. First, geometric analysis of the human body as an object of expression continues from the history of Cubism to modern fashion design. Second, the geometric shapes of the human body that appear in contemporary fashion design maximize visual effects through three-dimensional composition, emphasizing simplicity while showing originality through various expressions. Third, when exploring the geometric shapes of a moving human body, it was possible to extract a wide variety of shapes and forms through drawing and simplifying the human body's movements. Fourth, the formative method of fashion design was introduced and used for the aesthetic combination of objects for fashion design through decomposition and combination. This study was able to show unique and diverse combinations of visually concise and ordered geometric shapes in the expression of fashion design by decomposing and combining them. The significance of these geometric forms is that they can diversify formative informativeness in the expression of fashion design with modern compositional beauty.

본 연구는 유가 사상이 신화적 사유와의 상호 관계성 속에서 어떻게 발전되어 왔는지를 고찰한다. 특히 원시 사유체계 및 신화적 사고와 연관성에 주목하여 유가의 이상적 인격체인 성인의 형성도 그 원류가 신화적 사유와 상호 관계성을 갖고 있다고 보았다. 이를 위해 신화적 사유 속에서의 성의 의미를 검토하고, 이것이 유가의 성인으로 전환되는 의미 변화를 검토하였다. 고대 인류에서 부족장은 신들과 교류하여 종교적으로는 인간과 신들을 매개하여 신들의 말씀을 인간에게 전함과 동시에 인간의 염원도 신에게 전달하는 이중적이며 중간자적인 역할을 수행한다. 신을 대신하여 정치와 종교, 교육을 총 망라하여 수행하는 제정일치의 통치자는 점차 종교와 현세적 정치권력이 이원화되는데, 현세적 권능 대신 도덕적 정당성을 통한 권위를 부여받은 새로운 인격체가 유가의 성인이다. 유가에서는 공자에서부터 맹자, 순자에 이르기까지 현세에서 이룰 수 없는 높은 수준의 이상적 도덕군자에서 시작하여 누구나 노력에 의해 다다를 수 있는 가장 모범적이고 이상적인 인간상으로까지 규정한다. 따라서 초기 유가의 성인 개념은 상대적으로 신화적 성인의 이상적인 권위에 주안점을 두어 인간이 다다를 수 없는 초절대적인 완성된 인간으로 상정되었다면, 이후의 유가에서는 점차 도덕적인 수양을 통해 누구나 다다를 수 있는 존재로 상정된다. 한편 문명을 전수하고 인간을 계도하는 역할은 완전히 사라진 것이 아니라 다시 현세의 권위와 결합하여 도덕적 성인의 권위까지 부여한 새로운 존재자로 재탄생한다. 이상과 같이 이상적인 인간상으로서의 성인이라는 매개를 통해 유가 사상과 신화적 사유가 상호 관계성 속에서 형성되고 발전되어 왔음을 확인할 수 있다.

This study aims at more exactly identifying current status and trend of the school violence in elementary schools. Many previous studies have addressed the issue with their own views and methodologies, and mostly ended up as one-time works without subsequent observation over years. From such respective studies, we could hardly figure out an integral and precise shape on the school violence in terms of fact and tendency. To my knowledge, this is the first time-lag design on the school violence which is conducted nation wide, where the same concepts and measures were applied to the population. The research conclusions are follows: (1) both offenders and victims of the school violence tend to increase, (2) compared 10 girls, boys have more experience of the school violence, and (3) both offenders and victims could be recruited from the same group.

In this paper, we examined the effects of emotional and individual variables on flow in the usage of mobile application. We selected four relevant emotional and individual factors such as positive affect, negative affect, addiction and habituation. We also attempted to figure out the moderating role of communication in the effect of positive affect, negative affect, and addiction on the flow. For empirical analysis, we surveyed real users of mobile application and applied PLS (Partial Least Square) methodology for SEM (Structural Equation Modeling). As a result, we found that positive affect, addiction, and habituation have significant and positive impact on the flow. Furthermore, we also found that the moderating effects of communication on the relationships between positive/negative affect and communication are significant. Our findings provide important theoretical grounds for the effects of human behavior and emotion on the flow of mobile applications. Lastly, we also suggest significant managerial implications for the development mobile applications industry.

If we want to compare the form of two objects, the human vision takes into account the parameter's width/length/height at the same time. however, the machine needs to compare width then lengths and finally height. In each comparison the machine considers only one character. The goal of this paper is to imitate the human manner of comparison and recognition by using two or three characters instead of one during the comparison. The ellipse is a first approach of comparison because it provides us a general and a simple relation that can link two parameters that are the half axis of the ellipse. Indeed, we assimilate each character to a half axis of the ellipse and the result is a geometrical figure that varies according to values of the two characters.

The purpose of this study was to investigate on what kinds of consumer confusion exist and how much confusion consumers experience during their information search process. In-depth interviews and a questionnaire survey with college students were conducted to figure out the type and the level of consumer confusion. Results showed that college students were somewhat confused when they chose information channel and when they understood and used the chosen information. It was found that confusion was due to partly because of too many information and partly because of the lack of consumer searching skill.
