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.

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.

안전한 인터넷 뱅킹 서비스 제공 모델 및 인증 기법 설계

이재식 숭실대학교 2013 국내박사

정보통신 기술의 발달로, 인터넷을 통하여 많은 서비스들이 이루어지고 있다. 최근에는 개인용 컴퓨터뿐만 아니라 스마트폰으로 대표되는 모바일기기에서도 서비스가 이루어지는 등 서비스를 제공하는 영역이 확장되고 있다. 이처럼 인터넷을 통하여 온라인상으로 다양한 서비스들이 제공되고 있으나, 타인의 이용자 정보를 이용하여 서비스를 이용하거나, 악성코드 및 바이러스 등을 이용하여 정상적인 서비스 흐름을 방해하고 서비스 내역을 조작하여 비정상적으로 금전적 이득을 취하는 등 인터넷 환경에서 이루어지는 서비스를 대상으로 하는 많은 공격이 발생하고 있다. 국내의 경우 인터넷 뱅킹으로 대표되는 금융서비스도 인터넷을 통하여 제공되고 있으며, 특히 공인인증기관을 이용한 공인인증서 제도를 통하여 실시간계좌이체가 가능한 인터넷 뱅킹 서비스를 제공하고 있다. 하지만 이러한 인터넷 금융서비스 중 상대적으로 보안성이 높다고 평가되는 인터넷 뱅킹에서 조차 최근까지도 피싱, 파밍, 스미싱 등 다양한 기법으로 금융보안 사고로부터 피해가 발생하고 있다. 보안사고가 발생하면 그에 따라 새로운 인증 수단을 도입하거나 보안정책을 변경하는 등 추가적인 사고 방지를 위해 다양한 인증 기법을 적용하고 있으나, 이러한 인증 수단 적용 및 도입에 대한 명확한 기준이 없어서 그 실용성에 문제가 제기되고 있다. 이에 본 논문에서는 인터넷 뱅킹 환경에서 제공되는 서비스를 안전하게 제공하고 제공받을 수 있도록 안전한 인터넷 뱅킹 서비스 제공에 관한 모델 및 인증 기법을 제안한다. 제안된 인터넷 뱅킹 인증 기법은 스마트기기의 안전한 영역에 인증서를 저장하고, 이를 이용하여 전자서명을 생성하는 구조를 가지고 있다. 또한 서비스의 이용에 필요한 중요정보는 스마트기기를 통하여 입출력하는 구조를 가지고 있어서, 이용자의 PC가 안전하지 않은 경우에도 서비스의 전체적인 안전성이 떨어지지 않는 특징을 가진다. 제안하는 인증 기법을 활용하여 안전한 인터넷 서비스의 제공이 가능할 것으로 기대한다. Lots of services are being realized through internet due to development of information and communication technologies. Recently, the area of service provision is expanding, for instance, to those not only on personal computers but mobile devices represented by Smartphone. Like this, various services are being provided online through internet, but a lot of attacks on services realized on internet environments are taking place, such as using internet services by stealing information of other users or abnormally deriving monetary benefits by interrupting regular service flows with malicious codes or viruses and manipulating service details. Domestically, financial services represented by internet banking are also being provided through internet, and especially internet banking services that enable real-time account transfers through officially approved authentication certificate systems of qualified authentication institutions are being offered. However, even the internet banking being assessed to have relatively high security compared to other internet financial services is getting damages from financial security accidents due to various techniques such as Phishing, Pharming, or Smishing. When security accidents take place, diverse new authentication techniques, such as introducing new authentication tools or changing security policies, come to be made and applied to prevent additional accidents, but questions regarding their practicality come to arise because there is no clear standard for applying and instituting those authentication tools. Thus, this paper suggests safe internet banking service provision models and authentication techniques to safely provide and receive internet banking services. The internet banking authentication techniques proposed have a structure that saves authentication certificates in safe areas of Smart Devices and produces electronic signatures by using them. And because they also have a structure to input and output information important for using services through Smart Devices, they have a characteristic that the overall safety of services doesn’t get deteriorated even when PC of users are not safe. It is expected that safe internet banking service provisions will come to be possible due to proposed authentication techniques.

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.
