Nog-Moon Yim Seong-Joo(녹문 임성주) is a philosopher of late Choseon Dynasty of the 18th Century. He concluded that the debates between the school of Ho and that of Rack originated from the seclusion of Li(理) and Ki(氣), and theorized the new Li and Ki theory according to his own perspective. The prime point of Nog-Moon's Philosophy is said to be Li-Ki dongshil(理氣同實), Mind and Nature ilchi(心性一致) ; he proves his prime potints based on his pure and clean Ki substance. Thus Li-Ki is reduced to monism from dualism, and Mind-Nature(心 性) is reduced to mind. Since the basis of the existence of Mind is Ki(氣), Nog-moon's theory of Substance is concluded to be Ki-monism. Nog-Moon presents his great philosophy of Ki monism suggested by Jeong Myeong-Do's monistic methodology; he explains the universality of Substance and the diversity of Phenomenon with the logical structure of ilwonbunsu(一原分殊). The characteristics of Nog-Moon's philosophy is that ilwon(一原) and bunsu(分殊) are bonnyeon(本然) identical, which means Substance and Function(體用) are identical, or bonmalilchi(本末一致). It means Mind and Nature are bonnyeon(本然) identical, Ki and Mind and Nature are identical. With the expression of seongrihak (性理學) Gijil(氣質) is not different from bonnyeon(本然). Therefore 1 define the philosophy of Nog-Moon had been built on the context of a sage.

This paper presents a semantic object extraction method using user's stroke input, color, and depth information. It is supposed that a semantically meaningful object is surrounded with a few strokes from a user, and has similar depths all over the object. In the proposed method, deciding the region of interest (ROI) is based on the stroke input, and the semantically meaningful object is extracted by using color and depth information. Specifically, the proposed method consists of two steps. The first step is over-segmentation inside the ROI using color and depth information. The second step is semantically meaningful object extraction where over-segmented regions are classified into the object region and the background region according to the depth of each region. In the over-segmentation step, we propose a new marker extraction method where there are two propositions, i.e. an adaptive thresholding scheme to maximize the number of the segmented regions and an adaptive weighting scheme for color and depth components in computation of the morphological gradients that is required in the marker extraction. In the semantically meaningful object extraction, we classify over-segmented regions into the object region and the background region in order of the boundary regions to the inner regions, the average depth of each region being compared to the average depth of all regions classified into the object region. In experimental results, we demonstrate that the proposed method yields reasonable object extraction results.

In this paper, I examined two things. First explore the of the reality(眞) in poems written on paintings and discussion on paintings in men of letters of Pre-chosun dynasty, furthemore, it analyzes the meaning and thought. To explain it, I would like to analyse the discourse surrounding the reality(眞) in poems written on paintings and discussion on paintings, and concept of the borrowing(假) and the unreal(幻). First of all, I examine the ways that the view of nature of Confucians is pertinent to the abiding in reverence and the investigation of principles of confucians, also painting is necessarry condition for their moral and spiritual self-cultivation. In the discourse surrounding the reality, it is to suggest from 'natural reality (天眞)' to escape from the reality(眞), and proceeds to examine the transformation of reality(眞) in mind(人心). Furthermore I examine the meaning of transform and delicate difference between borrowing(假) and the unreal(幻). In this process, concept of the borrowing(假) and the unreal(幻) is divided into the two meaning. False(假) is to become the Borrowing and painting, the unreal(幻) is change into the act of recognition. In conclusion, I examined the significant transformation of the reality(眞) and the unreal(幻). The reality(眞) has been recognized as a important concept, it is diverged into the Nature, outer things and painting mind, and the object of ultimate value in appreciation and painting of Pre-chosun dynasty.

The hydrologic response function in a small basin is expressed by the distribution function of slope length. The characteristics of topographical factors is represented to the concentration time, and the instantaneous unit hydrograph is derived as a hydrologic rsponse function by application of probobility density function. The averaging process of runoff characteristics within watershed was analyzed for a few small watershed where was split up the small basin itself. The method of calculation of the effective rainfall should play important roles in the transformation process from hydrologic response function to runoff hydrograph. In this paper, the Horton's infiltration quation is used as a method of calculation of effective rainfall, a new response function of runoff process is derived. The $\Phi$-index method and the infiltration method are tested by comparing the observed and estimated values.

Colored dissolved organic matter(CDOM) is an important component of ocean color that can be used as an invaluable tool in water quality and ocean color studies. With the largest source of coastal CDOM appearing to be from freshwater discharge into the ocean, coastal predictive models will do much to refine our knowledge about major processes that control CDOM distributions in coastal waters and provide a better insight into the global carbon cycle. This study aims at developing a GIS-based watershed-scale predictive model of CDOM distributions in Neponset river watersheds that can be used to appraise our understanding of CDOM sources and distributions in coastal waters and predict the response of CDOM concentration to changes in land use patterns. Weighting factors are developed for CDOM freshwater sources after extensive groundtruthing from various landuse types in the watershed. This model makes use of a publicly available DEM(Digital elevation model) as the base data for analysis. Stream networks, discharge, and land use data are used from public repositories while sub- watershed delineation, pour-points, and land use parcels are generated using Spatial Analysis of ArcGIS 9.2 to estimate the CDOM loading from various sources to the lower tributaries of rivers. The Neponset Watershed in eastern Massachusetts is selected as the site for development of the model.

In this paper, we propose the development and application of a software education program for underachievers. The software education program for underachieving students was developed in consideration of the characteristics of learner's suffering from underachievement and the educational effects of software education, and is meaningful in that it proposes a plan to improve the learning gap in distance learning. Learners can acquire digital literacy and learning skills by solving structured tasks in the form of courseware, intelligent tutoring, debugging, and artificial intelligence learning models in educational programs. Based on the effects of software education, such as enhancing logical thinking ability and problem solving ability, this program provides opportunities to solve fusion tasks to underachievers. Based on this, it is expected that it can have a positive effect on the overall academic work.

In this paper, to provide an idea for the 2022 revised mathematics curriculum by restructuring the content of the 2015 mathematics curriculum, the content elements of recurring decimals of textbooks, which showed differences in the curriculum of Korea and Japan, were analyzed. As a result of this study, in Korea, before the introduction of the concept of irrational numbers, repeating decimals were defined in the second year of middle school, and the relationship between repeating decimals and rational numbers was dealt with. In Japan, after studying irrational numbers in the third year of middle school, the terminology of repeating decimals is briefly dealt with. Then, when learning the concept of limit in the high school <Mathematics III> subject, the relationship between rational numbers and repeating decimals is dealt with. Based on the results of the study, in relation to the optimization of the amount of learning in the 2022 curriculum revision, implications for the introduction period of the circular decimal number, alternatives to the level of its content, and the teaching and learning methods were proposed.

The purpose of this paper is to provide a unified examination of apparently quite different gardens in terms of Carl Jung's psychological concepts such as Archetypes, Individualization, and a natural tendency towards balance or wholeness. In Jung's psychological framework, Archetypes are innate, universal prototypes for ideas and function as the first original models upon which all other similar persons, objects or concepts are derived, copied or patterned. Jung proposes that Individualization be achieved through a natural tendency towards balance, especially the balance between the conscious and the unconscious. This paper deals with three gardens, each of which represents a distinct cultural region: Bu-Yong Ji(芙蓉池) at the Changdeok Palace(Oriental), the Patio of the Lions at the Alhambra(Islamic), and the Fountain of Apollo at the Versailles Palace(Western). It is argued that all of three have in common a natural tendency towards balance and symbolize mandala, the archetype of wholeness. Bu-Yong Ji is in the form of quadrangle which embodies Yin and Yang. In the Patio of the Lions, the basin at the center and the four channels, which symbolize the waterway of the Garden of Eden and the four rivers in Paradise respectively, are constructed in the form of a quadripartite composition. The overlapped circle and rectangular shaped pond of the Fountain of Apollo also represents mandala. Symbols representing the same archetype can vary from culture to culture. This explains the differences among the three gardens with respect to specific aspects of external forms. In other words, an archetypal image can give rise to various forms in different cultures, and thus quite different mediums of design or design details may be developed. In conclusion, the three gardens give us a good example as to how an archetypal image can be expressed in different ways from culture to culture and how seemingly different design details can be analyzed in a unified way.

In this paper, aspects of equalities with monomial left-hand side presented in Korean elementary school mathematics textbooks are analyzed focusing on the component of expressions. According to this analysis, the textbooks deal with equalities with monomial left-hand side as though the students already know them, rather than to introduce and deal with them systematically. In this paper, the following four suggestions based on this analysis are proposed as conclusions. First, A-type equalities (with one kinds of calculation symbols and two or more numbers, variables, denominative numbers in the right-hans side) and B-type equalities (with two or more kinds of calculation symbols and two or more numbers, variables, denominative numbers in the right-hans side) may need to be introduced by the explicit description. Second, it is necessary to establish clearly the order of dealing with numeric expressions, expressions with ${\Box}$(blank) expression, expressions with words, expressions with ${\Box}$(variable), expressions with variables. Third, it needs to be noted that equalities with monomial left-hand side cab be used with a variety of meanings. Fourth, it is necessary to widen the range of the number constituting equalities with monomial left-hand side to the natural number 0 and as well as fractions, decimals.

The purpose of this paper is to investigate Chu Hsi's theory of Ge Wu by analyzing the $L{\ddot{u}}$ shi daxuexie (呂氏大學解) in the Critique of Adulterated Learning (雜學辨). Critique of Adulterated Learning was written by Chu Hsi(朱熹) for the purpose of criticizing the confucian scholars who inclined to Taoism and Buddhism. Chu Hsi criticized $L{\ddot{u}}$ Pen-chung(呂本中)'s theory of Ge Wu Zhi Zhi, especially focusing on his understandings based on the Buddhist tendency. $L{\ddot{u}}$ Pen-chung considered Ge Wu Zhi Zhi as the processes of emerging Liang Zhi of the Subject to discipline by investigating the Li of things. He said "Regard an awakening as the standard of Ge Wu Zhi Zhi", as he payed more attention to the mind of the Subject rather than a long process of accumulation of Li. In comparison with him, Chu Hsi considered enormous each step to accumulate Li as more important to reach the completions of knowledge. Especially, while grasping Li, he considered they should have an understandings of things from the routines to the origins of the principles - that is from the principles of things to the reasons of things are. Chu Hsi approached to the Ge Wu in the meaning of political theory in his early days. However, Chu Hsi expands the width of his thought with a theoretical tool of 'Li-i fen-shu (理一分殊)' in the course of criticizing $L{\ddot{u}}$ Pen-chung's theory of Ge Wu Zhi Zhi. In that sense, His criticism of $L{\ddot{u}}$ Pen-chung(呂本中)'s theory was not only the process of struggling against Buddhist philosophies, but also the process of deepening of his philosophy.
