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.

This study examines the ways in which Confucianism developed in connection with other thoughts. Mythology especially had an great impact on the formation of Confucian thoughts. This study focuses on the concept of sage and examines how Confucianism and mythological thoughts influenced on formation and reformation of the concepts. In ancient religion, sages as a hierophantic figure, mediates human beings and gods, delivering the gods' messages to the human and the human's wishes to the gods. The fused role of shaman and ruler began to separate. A new type of leader without political power, but with a religious role with a moral authority is the Confucian concept of sage. A sage in Confucianism is an ideal person like Confucius, Mencius, and Xunzi, an ordinary person can attain with effort. Anyone can become a sage in Confucianism. The early Confucian sage was more like a hyper-human with unaccessible authority in mythology. Later, a sage in Confucianism began to be described as a model figure that any human being can become. The aspect of shamans and diviners (wushi 巫師) did not disappear, but merged into a kingly power and transformed into a sage-king with moral authority. The new images are reflected in Confucian ideology of statehood or its religiosity. This study has explored the ways in which Confucianism and mythological thoughts interacted and influenced to each other through a concept of sage as an ideal personhood.

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.
