Phytolith는 식물 세포내, 세포벽 또는 세포간에 축적되는 현미경적 구조의 무기염류의 구조물을 통칭하는 용어이다. 그러나 현재까지의 연구들이 주로 규소의 축적에 의하여 형성되는 식물규소체를 중심으로 수행되었기 때문에 현재는 식물규소체를 지칭하는 용어로 흔히 사용되고 있다. 식물규소체는 화본과 식물의 분류에 유용한 형질이며, 미소화석으로 그 효용성이 토양학, 고생태학, 고고학 등의 분야에서 입증되었다. 또한 근자에는 발암물질로의 가능성도 제시되고 있다. 본 문에서는 식물규소체의 특성과 이들의 분석 그리고 식물학적 이용과 더불어 여타 분야에서의 이용 가능성을 소개하고자 한다.

The purpose of this study was to define teachers' learning motivation strategies and students' responses by analyzing science classes and interviews. The subjects were first grade and sixth grade teachers and students of an elementary school. The analysis tools are based on Keller's ARCS theory. The differences of teachers' motivation strategies were analyzed by grades and teachers' and students' backgrounds. The interviewers were composed of three teachers and three students of first grade, and three teachers and three students of sixth grade. The data were collected by recording of the classes using tape recorders, video cameras, and notebooks written by researchers. The results are as follows. First, teachers had their own styles of teaching strategies in their classes. Especially teachers' teaching backgrounds affected on the teachers' instructional strategies. The teachers who had long teaching experiences of lower grade students used to show a lot of attention strategies. While the teachers with long teaching experiences of higher grade students used to show few learning motivation strategies. Especially, sixth grade teachers used to show fewer confidence strategies than first grade teachers. Second, all of the teachers used to show few satisfaction strategies commonly in all the classes observed. Third, the students' recognition of the motivation strategies were not different according to their conceptions or activities of the classes. Commonly first grade students focused on the attention strategies, while sixth grade students focused on negative motivation strategies. Fourth, the teachers who believed that students need detail guidance and control recognized the needs of satisfaction strategies by students' autonomous activities after observing video tapes of other teachers' classes.

Purpose: This study was conducted to develop a comprehensive cognitive rehabilitation program that can be easily applied to brain injured patients by family members or nurses in community or hospital settings. Methods: A Systemic literature review design was used. Thirty-three related studies were reviewed. Result: Based on the results of the literature review, the training tasks for attention were designated to enhancing 4 hierarchical areas, i.e., focused, selective, alternating, and divided attention. On the other hand, the memory rehabilitation tasks mainly consisted of mnemonic skills, such as the association method which helps patients memorize given information by linking together common attributes, the visual imagery method, and self-instruction method. The problem solving rehabilitation program included a task of games or plays which stimulated the patients' curiosity and interest. The training tasks for problem solving were to encourage the process of deriving reasonable solutions for a problematic situation resembling real problems that the patients were faced with in their everyday life. Conclusion: It is expected that the cognitive rehabilitation program developed from this study could help patients having difficulty in their every day life, due to a reduced cognitive ability resulting from brain injury, to effectively adapt to every day life.

Devastating RC structural failures in the past have identified that the behavior of beam-column joints is more critical and significantly governs the global structural response under seismic loading. The congestion of reinforcement at the beam-column joints with other constructional difficulties has escalated the attention required for strengthening RC beam-column joints. In this context, numerous studies have been carried out in the past, which mainly focused on jacketing the joints with different materials. However, there is no comparative study of different approaches used to strengthen RC beam-column joints, from efficiency and cost perspective. This paper presents a detailed investigation carried out to study the various strengthening schemes of exterior RC beam-column joints, viz., steel fiber reinforcement, carbon fiber reinforced polymer (CFRP) strengthening, steel haunch strengthening, and confining joint reinforcement. The effectiveness of each scheme was evaluated experimentally. These specimens were tested under horizontal loading that produced opening moments on the joints and their behavior was studied with emphasis on strength, displacement ductility, stiffness, and failure mechanism. Special attention was given to the study of crack-width.

This study focused on the accessory of clothes of minority groups in Yunnan province to further the research about specific accessories' development in the future. Among the minorities in Yunnan, this study centralized characteristics of ornaments, hats and belts among five minority groups such as the Bai, Zhuang, Hani, Dai, and the Zang as representatives to study in detail because these five ethnicities have a relatively long history and plentiful information. The results are as follows: First, exaggeration means large gorgeous patterns that attract attention. Generally, there are many natural resources that can be used in places where these minority groups live such as gems, gold, silver shells and animals' horns, bone, teeth and the like. Headdress includes combs, loops, hairpins and other similar articles. Second, nature is a very fundamental part that people rely on for existence and development. The production and living that people need in life all depend on nature. The design of accessories is made from animal forms and patterns of clothes are presented through embroidery and wax printing. Designers always tried to add natural elements to their works. Third, symbolism consists of two aspects: One is the people's imagination, which related to actual materials, and the other is the product of imagination that provides better conditions to inspire people when they design. In China, most minority groups believe in Buddhism. The symbols in the clothing show their devout faith. Even the method of wear has many special implications like the use of accessories and length of clothing. The pattern of dragons and use of golden, red and other colors all have a proper symbolic significance in modern designs.

The existing approaches to the body painting have been dominated by the angles focused on the 'performance' and the 'body art'. The performance-focused approach, in which body painting serves simply as a make-up for the performer, one of the elements of performance to help it communicate effectively its meaning and come to perfection, might be in itself lacking in the attention to the placement of the body painting as a new genre of art. This thesis has two aims to explain the concept of Allegory as the contemporary meaning and to examined the formative characteristics and other characteristics of Allegory through theoretical research. For this purpose, this study is based upon allegorical cognition of Walter Benjamin and the allegorical method of Craig Owens. The formative characteristics of allegory are summarized as appropriation, deconstruction and site-specificity as follows. First, the constructed result has contrived characters because its image which derived from body painting based on the past shown image. Second, Allegoric body painting refuses an aesthetically valuable piece which can be interpreted formal completion, it shows intactly deconstruction of its configuration, substance and style. Third, Allegoric body painting has site-specificity facts which can be expressed for diverse meanings. Through these facts, the final goal of this thesis will find specific character for Allegory and apply to body painting.

The number of children wearing make-up is increasing. "Children's cosmetics" is not a legal term though it is commonly used. The purpose of this study is to analyze discussions on children's cosmetics based on news articles found on the internet. This study also identifies what products are being distributed as children's cosmetics. Keyword searches were conducted using internet portal sites. Information was extracted from news articles and Best Item 100 for children's cosmetics. The results of analyzing news articles and Best Item 100 lists are as follows : 1. There were two main discussion topics in news articles. The first topic was related to marketing(the branding and trends of children's cosmetics). The other topic was about government regulations(side effects, harmful ingredients, control, regulations, attention, proper product usage, product categorization, and the overall safety of children's cosmetics). By 2014, many articles had covered government control and regulation. However, since 2017, news articles have focused on the product categorization and the concern for overall safety has dramatically increased. 2. Three different product categories have appeared in the Best Item 100; they are cosmetics, toys, and other products. In market, consumers recognized children's cosmetics as cosmetics and also as toys. Between 2017 and 2018's Best Item, other products are dramatically down, color cosmetics and single cosmetics are on the rise, and the purchase of domestic products has increased.

Costs have long since become a major issue in railway system analysis, attention is not limited to the acquisition costs alone, but encompasses all costs involved in the use and disposal of the systems. Concepts such as Life Cycle Cost(LCC), Costs Of Ownership(COO), or Total Ownership Cost(TOC) are more and more frequent in any document dealing with system analysis. Most of railway projects have applied this LCC Model to evaluate effectiveness of system acquisition cost. But these action of LCC model does not applied all the rest of system life cycle period due to the differences of its responsibility. This is why a study has been undertaken by the operation party to harmonize the most important aspects of the LCC model. This study focused on these and other objectives for introduction of method and needs for an action plan for maintenance actions involved relevant cost allocation.
