A Study on Calligraphy of Toegye Lee Hwang - Focused on his Understanding of Beauty Showed in his Calligraphy - Lee Jae - Sik Dept. of Calligraphy Graduate School, Daejeon University (Directed by Prof. Jeong Tae-Hee, Ph.D.) Abstract Scholars of Sung Confucianism explained diverse matters related to human nature based on their doctrines. In addition, they put self discipline and the attitude toward real life as a priority in their philosophy. The scholars including Chu-Hsi argued that man should express minimum level of human desires in creating arts. They thought the expression should be fit in the contemporary morals, and considered it very negative if it went beyond the morals. They understood arts based on the thought of abstinence. They believed that the basic principles of the nature control human nature and man show their mind in arts, but the mind shouldn't go beyond manners. According to Chu-Hsi, the basic principles of the nature are the nature of appreciating beauty, but self-discipline of human nature should be the premise of creating arts. Therefore, the ideal state of oneness of God and man, which scholars of Sung Confucianism pursued to reach in the arts, can come true when man unite with the universe and the nature through self-realization and self-experience. Toegye, who established his own school escalating up Chu-Hsi's Sung Confucianism, understood intrinsic nature and the phenomenon in two different ways. He believed that the basic principles come before the atmospheric force of nature in understanding the intrinsic nature. However, they come together in understanding the phenomenon of style. His understanding in the intrinsic nature regarding Taegeuk pattern of yin-yang and a state of things are more materialized than that of Chouunien-Hsi or Chu-Hsi.ure in uunderstood Chu-Hsi's theory han thaown way so that he presented his unique theory that the basic principles of the nature could move themselves with their own energy. He fand a stateuman morals based on self realization and intended to find a basis of goodness iateuman mind. His idea of pure goodness iateuman mind comes from his is idea of his is idmd t activelf delf op his iure goodness if the goodness from heaven is givenlves with their teumathis regard,ure in ufand a smore tateuman their , which hasn't delf opa syet because the human nature would become good after self-discipline. So the study for self-discipline will develop into the idea of participation in a society as they grow in mind and body. This Toegye's thought appears in his arts as a way of realizing and expanding the intrinsic value of the manifestation of principles. He reflects in his calligraphy his view on basic principles and the atmospheric force of nature as two different things. Toegye believed arts and literature play an important role in nurturing human mind. He suggested his view of arts and literature with which man could overcome dirty mind and become healthy. In other words, he expressed his belief that arts and literature have a mission to discipline human mind. He thought arts and literature was one way of expressing his morals and disciplining his nature. Take a look at his calligraphy as his one way of creating arts. First, writing reflected a man and next, the writing showed the man's personality. Here, we can see that he sublimated his idea that human manners and writing become one in the idea that morals and writing become one. Toegye's writing is one way of realizing personality. The style of his calligraphy comes from his personality as a result of his studying and discipline. He refrained himself to use too many techniques in his writing. He pursued writing as a place to practice of Taoism whose secrete is to wake uaoand watch your mind,oand keep studying what's what. Pure and clean mchniin his writing style, which is plain without any tricks showse is of Chu- z's idea. His calligraphy, which is simple, plain and mctd also, showsehis moderate attitudeiin creating arts. The expression of his writing is possible only at the state in which I and the nature become one. In that state, the conflicts between human heart and things are resolved and so letters look alive and outstanding. Toegye, who stuck to his style based on his view of human nature, sought for a world in which I and the nature become one through calligraphy as an expression of his heart. By doing so, he was free from techniques and he reached a joyful state of himself as a completely congruent person, which was his goal to pursue in his arts. It's hard to see uniqueness, high creativity, toughness or refine details in his calligraphy. Instead it looks simple but classy, plain but strong, mild but spiritual, and quite ordinary but potential in variation. That's why the more we see the letters the more respectful we become for him. Today, many calligraphers pursue his style. Everything they think they have to learn is in his handwriting, which is his decent personality. That is a good enough reason for them to pursue.

Due to the development of wireless networks, routing in ad hoc networking has been an active research area in recent years. However, the environments of ad hoc network tend to have vulnerable points from attacks, because an ad hoc network is a kind of wireless network without centralized administration or fixed network infrastructure such as base stations. Also, most of the security routing protocols that are effective in a wired network become inapplicable in ad hoc networks. To address these concerns, several secure routing protocols have been proposed: SAODV and SRPTES. Even though these protocols is intensified security of networks than existing protocols, they can not deal fluidly with frequent changing of wireless environment. Moreover, a demerits in energy efficiency are detected because they concentrated only safety routing. In the thesis, I propose an energy efficient secure routing protocol for various ad hoc environment. The basic idea is divided a two parts. First of all I provide that the nodes distributes security information to reliable nodes for secure routing. The nodes constitute tree-structured with around nodes for token escrow, this action will protect invasion of malicious node through hiding security information. Next, I propose multi-path routing based security level for protection from dropping attack of malicious node, then networks will prevent data from unexpected packet loss. As a result, this algorithm enhances packet delivery ratio in network environment which has some malicious nodes, and a life time of entire network is extended through consuming energy evenly. 무선 네트워크의 사용이 증가하면서 다양한 애드 혹 환경에서의 라우팅 프로토콜이 제안되고 있다. 하지만 애드 혹 네트워크라는 환경의 특성 상 보안상 취약한 문제점을 가지고 있고, 또한 기존의 유선 환경에서의 보안 라우팅 프로토콜을 적용시키기 힘들다는 문제점이 나타나게 되었다. 이에 따라 Secure AODV나 SRPTES 등의 보안성을 적용시킨 새로운 애드 혹 라우팅 프로토콜이 연구되고 있다. 이러한 보안 라우팅 프로토콜은 기존의 라우팅 프로토콜에 비해 보안성이 강화되었지만 다양한 무선 네트워크 환경의 변화에 유동적으로 대응하기 힘들다는 문제가 있다. 또한 보안적인 측면에 집중을 한 나머지 에너지적인 측면에서는 단점을 노출하고 있다. 본 논문에서는 다양한 애드 혹 네트워크 환경에 적용 가능하고, 기존의 보안 라우팅 프로토콜에 비해 에너지 효율적인 보안 라우팅 프로토콜을 제안한다. 기본 아이디어는 크게 두 가지로 나뉜다. 먼저 보안 라우팅을 위해 주변의 신뢰 가능한 노드에게 보안 정보를 나누어 저장한다. 이를 위해 주변 노드와 Tree 구조를 형성함으로써 보안 정보를 악의적인 노드로부터 숨길 수 있도록 한다. 또한 보안 단계를 통한 Multi-path를 구성하도록 제안하여 악의적인 노드의 Dropping Attack에 대비하고, 예기치 못한 Data Packet의 손실에 대해서도 효율적으로 대처할 수 있도록 한다. 결과적으로 이러한 알고리즘을 통해 악의적인 노드가 존재하는 환경에서 패킷 전송 성공률을 높이고 또한 각 노드의 에너지를 균등하게 소모함으로써 전체적인 네트워크의 생존 시간을 연장함을 볼 수 있었다.

ABSTRACT A Study on Moral Philosophy of Nature in T'oegye's Poetry Jae-sik Lee Department of Sino-Korean Literature Graduate School of Kong Ju National University Kong Ju, Korea (Supervised by Professor Dong-jae Lee) T'oegye's philosophical thoughts considered the aesthetic pursuit through literary art to be one way to realize and expand human's essential worth. His ontology of Yigibunsokron 理氣分屬論 and his ethics of Lisŏngiak 理善氣惡 reflected on his literary art. T'oegye thought that literary art deepened human mind and above all played an important role in revealing Li 理, i.e. Ponyŏnjisŏng 本然之性 and cultivating Simsŏng 心性. T'oegye explicated this process of mind cultivation through literary art with his clear literary philosophy in which one reached the stage of cosmic harmony by washing off penurious thoughts and inspired by natural beauty. It replaced the individual Suyangron 修養論 that literary art is just for cultivating human mind. If one sees the literary art that concerned about Tao through his aesthetics, there was an encounter between poetry and the man first and then the poetry and the character. He developed it to the humanity of Tomunilch'i 道文一致 from the aesthetics of Yemunilch'i 藝文一致. T'oegye's 'world of pure poetry' singing about natural objects sought to have the mind of nature as his own mind to the moral awareness of a self and the purity of a soul. To T'oegye, nature is the essence not only of human survival but of the life style. Therefore, his poetry expressed natural beauty with the wandering body in the mountain and formed aesthetics through appreciation of natural beauty. Sansuyusang 山水遊賞 for T'oegye was possible through internal cultivation of Yin 仁 and Chi 智. For only the matured character through cultivation could realize moral righteousness. Only the matured could have the foundation to pursue properly the beauty of nature. Human characters to him were the sources to detect the beauty in aesthetics. Therefore, T'oegye recognized Li of nature first to connect it to the Sŏng 性 of the human to cultivate Chayŏnjisŏng 自然之性, i.e. natural mind. Therefore, he constantly tried to coordinate the evergreen-ness of green mountains and the endlessness of flowing water with human nature. To him, the pleasure of seeing nature was like the pleasure of recovering human nature. Nature, for T'oegye, was the way to reach Tao through the formation of aesthetics. Poetry and prose were the space for Lakdo 樂道 singing the pleasure in nature. This means that his literary art was formed with complete restraint of emotions. It is because only the complete cultivation of one's character in Muyokjadŭk 無欲自得 would guarantee the embodiment of sublime aesthetical stage and would be able to express this through art. Properly harmonized sentiments allowed the leisure to see things generously and to realize the aesthetic ideal. T'oegye's poetry constantly aimed for Onyudonhu 溫柔敦厚. Because he thought the quality of Onyudonhu as the ideal, he did save no criticisms on works that were too passionate or unrestrained. His criticisms on Hanrimbyŏlgok 翰林別曲 or Yukga 六歌 were also on the point that they contained 'wonder', 'oddity' and 'lewdness' with their pursuit of formal originality to make people conceive wrong aesthetics. For T'oegye, the inheritor of Confucius philosophy, this could not have been acceptable. From this view, it was clearly confirmed that Onyudonhu was the basic condition and ideal end that must be the universal aesthetic ideal in T'oegye's literary art. ■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■ * A thesis submitted to the committee of Graduate School, KongJu National University in partial fulfillment of the requirements for the degree of Master of Literature Conferred in February 2010.

전사적 품질경영(TQM)이 조직성과에 미치는 영향에 관한 실증연구 - (주)한국동서발전을 중심으로

이재식 울산대학교 경영대학원 2006 국내석사

TQM은 1980년대 미국기업의 경쟁력 향상을 위해 개발된 경영혁신기법으로서 계량적 통계기법을 이용한 가시적인 품질관리 보다는 인간의 행동특성에 근거한 기업문화와 조직적 측면을 강조한다. 우리나라의 전력산업계는 전력산업구조개편에 관한 법률에 의해 2001년 4월 발전부문이 분리 독립하였다. 이는 민간자본의 원활한 유입을 유도하여 경쟁을 통한 산업효율을 제고하기 위함이다. 따라서 각 발전 자회사는 생산성 향상과 공기업 으로서의 사회적 책임을 동시에 부여받고 있다. 본 논문의 연구대상인 (주)한국동서발전은 회사 창립 후 괄목할 성과를 시현하고 있으나 회사의 지속적인 성장을 위해 내부역량을 응집할 수 있는 혁신적인 경영 기법을 필요로 하고 있다. 이에 발전회사에는 TQM이 가장 적합한 기법이라고 판단하여 실증연구를 위해 설문조사 후 결과를 분석하였다. 기업의 조직성과에 미치는 TQM 활동요인으로서 전략경영의 강화와 간부사원의 리더십 향상 및 인적자원의 애사심 제고를, 내부고객 만족도 향상 요인으로서 성과 보상의 공정성 확립과 업무절차의 간소화를, 외부고객 만족도 향상 요인으로서 고객친화적 업무처리와 비핵심 업무 아웃소싱 확대를, 조직성과 요인으로서 기업 이미지 제고와 원가절감 등을 선정하여 항목별 요인분석과 타당성 분석, 다중회귀분석을 실시하였다. 설문조사의 분석결과 발전회사에서 우선적으로 취해야 할 과제들을 요약하면 다음과 같다. 첫째 인적자원의 애사심 제고는 내부고객과 외부고객의 만족도 향상에 절대적인 영향을 미치는 요인으로 확인되었다. 따라서 회사에서는 종업원을 人的資源化하기 위해 사내 홈페이지를 지식포탈서비스 공간으로 변경한다든지 사이버 교육을 통한 상시 교육체계의 구축, 상급학교 진학자 학비지원, 멘토링 제도 시행 등의 조치가 필요하다. 둘째 내부고객과 외부고객의 만족도가 제고되면 성과 보상체계의 확립, 업무절차의 간소화, 고객 친화적 업무처리, 비핵심 업무 아웃소싱 확대 등의 요인이 활성화되어 회사의 조직성과가 높아지는 것으로 나타났다. 내부고객의 높은 만족도는 외부고객 만족도 향상에 가장 큰 요소로 작용한다. 따라서 내부고객 만족도 향상을 위한 방안으로 복지강화, 자기개발 지원, 개인별 고충처리 등 애사심 강화와 업무 몰입을 유도하면 더 큰 조직성과를 달성할 수 있을 것이다. 셋째로 TQM 활동 정도가 높을수록 기업이 추구하는 원가절감 및 기업가치 제고의 결과를 가져오는 것으로 나타났다. 따라서 전략경영의 요소를 강화하고 종업원의 인적 자원화를 통한 기업 이미지 제고와 원가절감을 도모할 수 있는 혁신조치들을 시행해야 한다. 본 연구는 발전회사를 대상으로 한 최초의 연구로서 큰 의의를 갖는다고 할 수 있으나 설문조사가 전체 사업장을 대상으로 이루어지지 못하였다는 점은 큰 아쉬움으로 남는다. 그리고 기업 조직성과의 핵심요소로 밝혀진 인적자원의 애사심 제고와 효용성 향상을 위한 연구는 본 논문의 완성도를 높이기 위한 후속과제로 삼고자 한다. 결론적으로, 발전회사와 같은 특수한 경영환경의 기업에서는 본 논문의 연구분석 결과에서 확인된 TQM 활동요인을 경영에 적극 반영함으로써 공기업으로서의 기업이미지 제고와 원가절감을 통한 회사의 수익성 향상과 같은 조직성과를 극대화할 수 있다고 본다.

이재식 全州大學校 1987 국내석사

Store image on consumers' buying behavior is very important factor for store marketing strategies, especially in changing environment of retail institutions. For the more, store preference, Patronage, and Loyalty are influenced by store image. The analysis of store image and the establishment of store image positioning strategies are necessary conditions for differential benefits from competitors and contribute for market share and sales volume of retail stores. This study has been made of theoretical review and empirical analysis. In chapter 2, a review is made about theoretical background knowledges of store choice models in order to find the importance of store image. In chapter 3, store image and its positioning are reviewed through the prior researches and studies. In Chapter 4, empirical survey is made, which puts emphasis on three department stores located at Jeonju city(Jeonju department store : A, Core department store : B Hanalum department store : C). The objects surveyed are 74 citizens and the hypotheses derived from theoretical studies are tested through statistical analysis. A summary of the empirical research is as follows. 1. Respondents belong to middle class, reach at department stores by public transportation vehicles, and spend about one hour on shopping activities with friends(neighbors) and family members. 2. Generally, B is more appealed than any others and general image of B is more attractive than those of A and C. The statistical difference among images of three department stores are significant. 3. Consumers rank (1) postpurchase services, quality and assortment of merchandise, salesman's kindness and information offering services when they choose the department stores. The consumers' evaluation of department store attributes about three department stores indicates significant differences statistically in location, quality and assortment, salesman's kindness and information offering, atmosphere, advertising and sales promotion, general services, physical attributes, and postpurchase services. Evaluation scores about B are more positive than those abut A and C. 4. The degrees of appealing of three department stores(A, B, and C) are explained 32%, 24%, and 38% respectively by the scores(importance of attributes x evaluation of attributes). The appealing of A is influenced by the image of postpurchase services and customer level, that of B is influenced by the image of salesman's kindness and information offering, and that of C is influenced by the image of postpurchase services, quality and assortment of merchandise, advertising and sales promotion with statistical significances. This study has drawn some recommendations based on the empirical survey for the image positioning of the department. 1. Department stores in Jeonju can use publice transportation vehicles and words of mouth in order to communicate desired images, and pay attention to develop the community department store culture with additional events and active activities beyond selling products. 2. A and C should attempt to change and develop the unique images for themselves. Especially marketing resources should be allocated for better postpurchase services because consumers consider them for the most important factor in choosing department stores and are best appealed by that factor. Next important factor is quality and assortment of merchandise for image development and positioning of them. 3. B should develop the specific, unique, and differential image positoing strategies because conumers perceive the positive image ambiguously without concrete attributes. Positive image of B may come from the scale of economics and good physical building attribute by much funds.

CDMA 이동통신 단말기의 복제방지 방안에 관한 연구

이재식 高麗大學校 工學大學院 2004 국내석사

Now, the mobile service is most important and popular service. And CDMA technology is used for this service with GSM technology. But these day, some of cloned mobile using CDMA technology is made and used for criminal acts. In this reason, new protection method to prevent a fraud copy will be introduced in this thesis. Each terminal using CDMA technology is distinguished with its own MIN and ESN. And most of mobile equipments using CDMA technology; mobile phone, PDA and etc, store its MIN and ESN in its internal memory. If who want to copy a mobile equipment, he/she can make cloned mobile equipment with rewriting MlN and ESN. Law prohibits this fraud copy, but these cloned mobile equipment are made. In this reason, many of mobile equipment manufacturers and mobile service providers use their own protection methods to prevent a fraud copy and to detect cloned mobile equipment using software algorithm. But these software algorithms can be terminated using special tools or software programs. New introduced protection method uses 'MODEL-ID' and 'OTP' registers. MODEL-ID is new unique number for each model of mobile equipment. It can distinguish which model is designed using OTP or not. And OTP register is used to protect the ESN and MODEL-ID from rewriting after producing mobile equipment. OTP register is the one time programmable register in flash memory that is used to store main program and NAM data of mobile phone. And this OTP register can be locked and then it can not be unlocked. Using that technology, in this protection method the ESN and MODEL-ID will be written in OTP register and then OTP register will be locked after producing mobile phone. If who want to overwrite the ESN to copy the mobile phone, it can protect the ESN from overwriting. Hardware and software design using this protection method are introduced in this thesis, but it is not fully implemented on commercial product. Furthermore, this research is expected to implemented on commercial product.
