The purpose of this paper is to reaffirm the logical framework of the saju analysis method by recreating the saju model of old-law to study and organize the theories of frame in old-law Myeongri, and then by organizing and comparing the logic structure of the saju analysis method of new-law and old-law. Some believe that Myeongri Theory first appeared in the world in the Warring States Period when they were active with Gwigokja and Naknokja as origin, while others believe that it was origin that "Okjokyeong" was written by Kwak-Bak of Eastern Jin after a while. Since then, Myeongri Theory, which had been organized by Won-Cheongang and Yi-Heojung, has undergone a major transformation since reaching the Song Dynasty Seo-Japyeong. Based on this point, the Myeongri Theory of the previous generation is called the Old-law, and the subsequent theory is called the New-law. The changes in the logic structure of the old-law and the new-law leave a big difference and disconnect between those. But comparative studies have confirmed that the philosophy and logic structure due to natural laws that have not changed much such as the symbolic system of nature called Yinyang & five elements and Cheongan-jiji, the idea of a heavenly response projected in the Three Wonders of heaven, earth and human, and the concept of generation and time in the position of year-month-day-time.

The western-style industrial forest management practice involving large scale clearcutting, silviculture with industrially desirable species, and inadequate consideration on ecosystem preservation, has faced severe criticisms from environmentalists, ecologists and conservationists. With an increasing concern about environmental degradation the general public has also been becoming vocal in demanding ecologically sound alternative forest management. An age-old practice of sustainable ecosystem management variously defined as community forestry, social forestry or homestead forestry, has received increased attention in recent days. This type of traditional, and often not very organized method of natural resource management has been practised in many countries from the prehistoric times. It is believed that with a clear understanding of the functioning of ecosystem and community needs, the existing landuse method can be developed into a more productive one. The nature of community forestry management will vary depending on the scale, geographical location, social/community structure and expectations. This article argues that although the rate of economic growth may be lower with community forestry than with industrial forestry, the former fosters the principle of ecosystem sustainability. Industrial forestry may have an initial high growth rate but often it is associated with unsustainable harvesting leading to ecosystem degradation. A review of the traditional methods of economic analyses shows that they do not take into account the many social and environmental costs associated with forestry. It is argued that a well managed community forestry can maintain the critical balance between economic and ecosystem sustainability. An integrated model of community/homestead forestry development is proposed by coordinating the extension services of the departments of agriculture, forestry and environment.

The changes in flora and distribution and structure of vegetation were monitored for seven years at a restored reach of an urban stream, the Yangjae Stream, southeast of Seoul, Korea. In the restored reach, diverse kinds of the close-to-nature stream restoration techniques were adapted and implemented in the winter of 1998-1999. The species numbers and diversity indices of riparian plants at the restored reach were higher than those at the unrestored reach seven years after the restoration implementation. But plant diversity was decreased from the early restoration stage of 1999 - 2001 to seven years after the implementation. The dominant species changed from a ruderal annual, Humulus japonicus, to a perennial, Phragmites australis. The floral structure was distinctly different between in the early stage and seven years later on the results of principal component analysis (PCA) because of decreasing in numbers of exotic or ruderal species and planted or introduced plants in newly disturbed habitats. The distribution areas of communities of Humulus japonicus and Erigeron annuus were decreased and those of communities Phragmites australis and Miscanthus sacchariflorus were increased after the restoration implementation. The results of detrended correspondence analysis (DCA) of plant communities revealed that the community structure were changed from the disturbed vegetations to the stable and natural vegetation after the restoration implementation. Total seven species of willows were found at the restored reach, of which two species were planted and the others were naturally introduced. The monitoring results showed that the stream ecosystem of the study reach were successfully recovered in flora and vegetation and could be used as a model site for the stream restoration in urban streams.

Most of the rivers which exist in nature are not a single river but the network that is composed of several branches and mainstreams. The river network are more complicated than other sigle rivers and streams. Therefore the hydraulic characteristics are sensitively changed by reduction and expansion of the width in the confluence or the variation of the flux. In this paper, the hydraulic characteristics were calculated by the change of the width and length in the confluence and the hydraulic model test. The deposit of confluence emerged at the left bank, right bank and the stagnation sector. As the total flow in the branch have increased, stagnation of the left bank and right bank have decreased. When the width of the downstream have been get smaller from 3 m to 2 m, the deposit of the left bank and right bank and stagnation sector have decreased. But as the eddy flow in the center of the confluence is occurred, the erosion has been increased. The result of this paper can be used as a basic data of water management around the junction and for maintenance on the ground of development of the river.

This study forecasts the trend of ethnic theme through market survey, concentrating on Los Angeles market. First, the background of ethnic theme was examined, and the present situation of shops, department sores, and headquarter was also surveyed. After that, fashion trend suitable for market was suggested by analyzing the life style of consumers through zip code. The results of the study are as follows. The conspicuous trend of '97 F/W retail stores is ethnic. This reaction to complicated modern life, and symbolizes the desirable evaluation on the simpleness of basic life and nature. The model of ethnic design is identified in natural clothing, primitive arts, ethnic culture and African theme. In short, this ethnic fashion is expressed as simpleness, naturalism convenience and freedom. On the other hand, the standard of general department stores such as Broadway and Robinson May which are the headquarter of this trend is to satisfy various consumers with various styles. Ethnic goods from Broadway has not arrived at the top for its introducing step. To elevate sales of these goods, promotion through VMD and suggesting various ethnic goods should be done. Besides, when analyzing the consumers of Beverly center Broadway, the target of these goods are mostly professional young people in their 25-34 and 35-44. The life style of these people emphasizes sophisticated life in aspects such as job-oriented activities, and up-to-date fashion. Especially, image is very important. They want individuality different from others. These images are diversified from simpleness, naiveness to sexy character. Accordingly, suggesting fashion trend satisfying the demand of consumers through market survey will make fashion market create infinite possibilities.

Yeoheon is a representative recluse and philosopher in the 17th Joseon dynasty. His contemporary intellectuals considered him as a sincere nobleman, Confucius in the Joseon, and moreover a saint, a cornerstone of culture, and a model for Confucianists. As a politician, he was regarded as practicing the stabilization of the people's livelihood and education, which are the key ideas of Confucian politics, when he serviced as a local governmental office twice. In addition, his ruler thought that he was right, wise, and modest, and therefore had the dignity of the old sage. His subordinates considered that he possessed the way of the old great ministers and the eye to see the current state of affairs. His theory of the Yijing is based on Cheng-Zhou learning, but developed their interpretation of the text. In addition, he discussed that Confucianism is a practical learning. His theory of the ritual was considered to follow Zhu Xi's works, but refer the old rituals and overcome the aspect of minor customs. His contemporary scholars thought that his theory of Neo-Confucianism revealed the essence of Li-Four and Qi-Seven theory regardless of scholarly parties, which were formed after Toegye and Yulgok. However, he proposed the Li-longitude and Qi-latitude theory in order to restore the real values, but it is similar to Yulgok's theory, which was criticized by the schools of Toegye and South Faction near Seoul. However, his theories revealed the fact that Joseon Confucianism cannot be simply differentiated as two major theories of "Centering on Li" and "Centering on Qi. In addition, his ideas of the universe and concern for the old showed that Joseon Confucianism is not just a theory, but is related to our lives and therefore practical in its nature.

This study is intended to review the poetic directing created by the aesthetics of silence of Claude Régy, a French director who carries out playwriting in silence, departing from conventions through the concept of "potentiality" proposed by Giorgio Agamben, an italian philosopher. Claude Régy stated, "What's fundamentally important is not to say what you want to say." Thus he tries to create the stage of "silence" rendered in overly slow, excessively segmented dialogues while selecting restrained minimal means. Agamben makes Bartleby who "prefers not to" as a cardinal model of his perfect potentiality, asserting that the nature of potentiality is revealed in the pause of actuality. As in Agamben's philosophy, Claude Régy's directing is also the "pause" of words and actions. This silence is not a return to actuality but a creation of the moment at which "the invisible" become visible. The silence of words or the silence of an empty stage with dim lighting is viewed by Agamben as potentiality that has "underlying passivity" and is "hospitable to non-existnece". In this light, this study is to create another direction for the theater arts of our time and the 21^st century and to extend the horizon of new directional modes. It aldo reviews the concept of Agamben's "potentiality" that provides critical viewpoints to "the artist without content", works directed by Claude Régy who has created his own distinctive styles of direction with the aesthetics of "slowness" and "silence", L'intérieur by Maurice Maeterlinck and Quel'un va venir By Jon Fosse.

The adsorption of molecular $NH_3$ on rutile $TiO_2(110)-1{\times}1$ surfaces was investigated using a temperature-programmed desorption (TPD) technique combined with a molecular beam apparatus. A quantitative investigation into the TPD spectra of $NH_3$ was made for $NH_3$ adsorbed on two kinds of rutile $TiO_2(110)-1{\times}1$ surfaces with the oxygen vacancy ($V_O$) concentration of ~0% (p-$TiO_2(110)$) and ~5% (r-$TiO_2(110)$), respectively. On both surfaces, non-dissociative adsorption of $NH_3$ was inferred from a quantitative analysis on the amount of adsorbed $NH_3$ and those desorbed. With increasing coverage, the monolayer desorption feature shifted from 400 K toward lower temperatures until it saturates at 160 K, suggesting a repulsive nature in the interaction between $NH_3$ molecules. At the very low coverage regime, the desorption features were found to extend up to 430 K and 400 K on p-$TiO_2(110)$ and p-TiO(110), respectively. As a result, the saturation coverage of monolayer of $NH_3$ was higher on the p-$TiO_2(110)$ surface than on the p-TiO(110) by about 10%. The desorption energy ($E_d$) of $NH_3$ obtained by inversion of the Polanyi-Wigner equation indicated that the difference between the $E_d$'s of $NH_3$ (that is, $E_d(on\;p-TiO_2(110)$) - $E_d$(on p-TiO(110)) was 14 kJ/mol at ${\theta}(NH_3)=0$ and decreased to 0 as the coverage approached to a monolayer. The observed adsorption behavior of $NH_3$ was interpreted using an interaction model between $NH_3$ and surface defects on $TiO_2$ such as VO's and $Ti^{3+}$ interstitials.

This study aims at exploring the features of science teaching orientation (STO) and its relationships with other PCK (pedagogical content knowledge) components. To do this, based on the definition of STO by Friedrichsen, Driel, & Abell(2011) and PCK model by Magnusson, Krajcik, & Borko(1999), we observed one experienced elementary teacher's science lessons for 21 lesson hours (10 hours of 'Motion of Objects' and 11 hours of 'Light and Lens') and carried out qualitative analyses of the data obtained from lessons observation, teacher interviews, and CoRe (content representation) responses. We analyzed the teacher's three aspects of STO (i.e. beliefs about the goals and purpose of science teaching, beliefs about the nature of science, and beliefs about science teaching and learning) which can converge into an overall STO of 'inquiry'. And these aspects of STO appear to interact differently with four PCK components (i.e. curriculum knowledge, learner knowledge, instructional knowledge, and assessment knowledge) depending on the topic of the lesson. It is hoped that this in-depth understanding of the features of STO and its relationship with other PCK components would provide useful information on how to monitor and improve STO and PCK of elementary teachers.

The purpose of this study is to analyze leisure factors affect happiness of the elderly by sex in Korea and then to discuss implications for the findings. Data of National Leisure Activity Survey conducted by Korea Culture & Tourism Institute in 2016 were used for this study. From this dataset, 891 male elderly and 970 female elderly aged above 65 were selected for this study. Ordered logistic regression model was used by considering the nature of the dependent variable. The results of this study can be summarized as follows. First, choice proportions of leisure activities classified by four type are different by sex of the elderly. Second, among control variables, household income, residential area, joining a club have different significant effect on happiness of the elderly by sex but volunteering have same significant effect on happiness of the elderly by sex. Third, any type of leisure activity have no significant effect on happiness of both the male elderly and the female elderly. Fourth, cost of leisure has significant positive effect on happiness of both the male elderly and the female elderly but has different significance by sex. Fifth, focus on leisure rather than work has very significant positive effect on happiness of both the male elderly and the female elderly. Sixth, leisure life satisfaction has very significant positive effect on happiness of both the male elderly and the female elderly.
