This study was carried out to examine that the SamJae Theory(三才思想) was applied for a philosophic background of medical ethics. SamJae theory is not the system of three categories, which is unlike to the meaning of the word 'Sam(三)', but it is the system of two categories with 天(陽) and 地(陰) which are dividing all creations and phenomenons in the universe into two. Nevertheless, the reason why we divide all the universal creations and phenomenons into three, 天, 地 and 人, and also why we give a name 'SamJae' to this theory using the word 'Sam' meaning three, is to emphasize the human free volition that comes from the independent human life in the universe composed of 天(陽) and 地(陰). In other word, the core concept of SamJae theory is not 天(陽) and 地(陰) but 人 which symbolize the independent free volition of human. Therefore, if we try to use SamJae theory as a philosophic background of medical ethics, we can establish a comprehensive theoretical system including the existing ethical theories such as utilitarianism.

It is very important problem that exactly distinguish constitution, in Sasang constitutional Medicine. But, it is careless that discuss the propriety of 'Sasang constitution unchangeability theory(四象體質 不變論)'. The foundation of Sasang constitution unchangeability theory is the sentence in DongUi SuSae BoWon Sa-dan theory(東醫壽世保元 四端論) : "The Organ system of Taeyang(太陽), Taeum(太陰), Soyang (少陽) and Soeum(少陰) is the variation of YinYang(陰陽), is firm nature and is unnecessary agreement. (太少陰陽之臟局 陰陽之變化也 天稟之已定 固無可論)". But, the foundation of Sasang constitution unchangeability theory contradict the theory that Organ system(臟腑) is made by deviation of emotions(joy, anger, sorrow and pleasure :喜怒哀樂) or temperament(性情). Because these emotions is revealed after birth(後天), the deviation of Organs system made by deviation of emotions is not innate, is acquired after birth. Therefore, it is necessary to discuss the opinion that Sasang constitution is variable after birth. The conclusion of our study is that Sasang constitution can be variable after birth.

In this paper we discussed a new methodology for Urdu Character Recognition system using Dempster-Shafer theory which can powerfully estimate the similarity ratings between a recognized character and sampling characters in the character database. Recognition of character is done by five probability calculation methods such as (similarity, hamming, linear correlation, cross-correlation, nearest neighbor) with Dempster-Shafer theory of belief functions. The main objective of this paper is to Recognition of Urdu letters and numerals through five similarity and dissimilarity algorithms to find the similarity between the given image and the standard template in the character recognition system. In this paper we develop a method to combine the results of the different distance measurement methods using the Dempster-Shafer theory. This idea enables us to obtain a single precision result. It was observed that the combination of these results ultimately enhanced the success rate.

This paper reviews Grammatical Mapping theory, a recently proposed theoretical paradigm for understanding children's acquisition of syntax, and ventures to apply the theory to the acquisition of semantics. Particularly, we focused on the domain of space, and proposed how children might acquire a unique system of spatial words in their mother tongue. Based on our review of evidence, we propose that there may be universal semantic primitives that serve as foundations of word meanings. We also propose that children must learn their mother tongue's semantic category system of spatial relations, from real time data. Finally, we argue that children's learning of word meanings may involve creation of a theory that makes sense to the child, and that this process of theory creation is possibly guided by universal principles and parameters.

Recently, a Game Shut-down policy, partially limiting the time for the use of online game service, has been implemented in order to protect the youth from the excessive use of games by limiting their access to games in the late hours, based on the serious side effects of online games on the youth. However, the effectiveness of a Game Shut-down policy becomes a social issue. Thus, this study aims to investigate the alternative policies through the levels of the communications suggested by the theory of excellence, for the successful implementation of the policy. As a result of the study, the government and students, the recipient of those policies, need to strengthen their two-way communication in respect of the Game Shut-down policy, breaking from the existing views on the perception. The problem is that the current government's way of the communication for the Game Shut-down policy is one-way and it is aiming at achieving the objectives only. Thus, the communication in this manner will cause the side effect. 'the opportunistic violation of the system in the future', even if the students seemingly accept the system. Two-way communication will enhance the motivation for the voluntary acceptance of the system and lower the motivation for the opportunistic violation of the system. Thus, the government needs to strengthen two-way communication in the future.

We get a theorem which shows the existence of at least four $2{\pi}$-periodic weak solutions for the bifurcation problem of the Hamiltonian system with the superquadratic nonlinearity. We obtain this result by using the variational method, the critical point theory induced from the limit relative category theory.

As the number of cyberattacks against the National Critical Information Infrastructure (NCII) is steadily increasing, many countries are strengthening the protection of National Critical Information Infrastructure (NCII) through the enactment and revision of related policies and legal systems. Therefore, this paper selects countries such as the United States, the United Kingdom, Japan, Germany, and Australia, which have established National Critical Information Infrastructure (NCII) protection systems, and compares and analyzes the promotion system of each country's National Critical Information Infrastructure (NCII) protection policy. This paper compares the National Critical Information Infrastructure (NCII) protection system of each country with the cybersecurity system and analyzes the promotion structure. Based on the policy model theory, which is a modification of Allison's theory and Nakamura & Smallwood's theory, this paper analyzes the model of each country's promotion system from the perspective of policy-making and policy-execution. The United States, Japan, Germany, and Australia's policy-promotion model is a system-strengthening model in which both policy-making and policy-execution are organized around the protection of the National Critical Information Infrastructure (NCII), while the United Kingdom and South Korea's policy-promotion model is an execution-oriented model that focuses more on policy-execution.

This thesis is a study on the relation of between Xiangshu Zhouyi Theory and mathematics, Zhouyi Theory as the one of the study of Chinese classics, was formed by Zhouyi' Eight Diagrams, the theory of Yinyangwuxing and the knowledge of natural science in Han dynasty. 'Xiangshu' had been regarded as the important concept and theory in the history of Zhouyi Theory From the beginning of Han dynasty to the end of Qing dynasty. At this developing of this Periodical Change, 'Xiangshu' had been endoded in the expression system of mathematics. This thesis considers binary system and surplus nembers, multiple and progression, magic square and circular constant, a proportional expression from Zhouyi Theory point of view. Xiangshu Zhouyi theory got the answer of these questions like the origin of Zhouyi, interpreting Guayao-word and Cosmology by using those expression systems of mathematics. Besides mathematics, Xiangshu Zhouyi theory was also related to astronomy, medicine, etc. Xiangshu Zhouyi theory had kept the pace with the general development of natural science. This thesis from the premise that Xiangshu Zhouyi theory kept the pace with natural science, summing up the mathematical expression system in the history of Zhouyi theory, proves that Xiangshu Zhouyi theory had developed according as the conditions of natural science.

It is proposed, for fuzzy combustion control system of refuse incinerator to find the relationship between inputs and outputs and to generate rules to control by using rough set theory. It is not easy to find out the corresponding inputs for each output and the control rules with incomplete or imprecise information consisting expert knowledge, process and manipulator values in the field, and operation manual for the given system. Most decision problems can be formulated employing decision table formalism. A decision table on fuzzy combustion control system for refuse incinerator is simplified and produces control(rules). The I/O realtions and the control rules found by rough set theory are compared with the previous result.

From the past until now, political and economic relations among countries have been one of the most important issues among analysts and numerous studies have tried to analyze these relations from different theoretical perspectives. The dynamic system of games has introduced a new modeling method in the game theory. In this study, we use behavioral models (level- k) along with the dynamic system in games to model rational agent behavior. As an application, we study Russia- Norway economic and political relations (1970-2019). The dynamic system in games along with behavioral games theory can be used to predict the players behavior in the future.
