지도는 기호, 주기, 색상, 경위선, 축척 등과 같은 여러 요소들을 사용하여 지도 사용자들에게 다양한 지리적 사상들(geographic features)의 존재와 그들의 상관관계를 전달하는 일종의 의사소통 수단이다(황철수, 2002). 주기(label)는 $\ulcorner$지역, 인공물, 자연물의 고유명칭 및 고유명이 없는 것의 종류 또는 상태 등을 표시하는 설명 및 표고와 등고선수치 등을 문자 또는 숫자로서 표기하는 것1)$\lrcorner$, 즉 지도에 나타나는 사상들에 대해 설명하기 위해 입력되는 문자열을 의미하는 것으로 지도의 여러 가지 요소들 중에서도 가장 직접적이고 구체적으로 사상을 표현할 수 있는 요소이다.

The current research investigates the basic philosophy that would serve as a foundation for the development of the service economy. In particular, the current work suggests that the Korean traditional philosophy fits the philosophy of the service economy because of the relational nature of the Eastern culture (vs. Western culture). Therefore, it is suggested that trough manifestation of the Korean traditional philosophy, the service economy would be invigorated. The yin-yang and the Two Taegeuk do not emphasize the role of human, and thus, a new philosophy incorporating this aspect needs closer attention. Therefore, the Korean traditional philosophy, structured in a Three Taegeuk framework could serve as the foundation for the development of the service economy. The Three Taegeuk framework relates to the harmonization, horizontality, bi-directionality, and relational aspects of the service industries. For example, human serving the agent role in the society resembles the current service economy where service workers and customers serve important roles in value creation. Taken together, the current research suggests that the Korean traditional philosophy serve as an important foundation for the development of the service economy.

이 논문에서는 Dirichlet 경계 조건을 갖는 비선형 빔방정식 $u_{tt}+u_{xxxx}+g(u)=f(x,t)$의 해의 존재에 대한 연구를 하였다. 이 때 $g(u)=bu^+-au^-$으로 나타나고 우변의 외력항이 고유함수 $\{{\phi}_{00},{\phi}_{41}\}$로 확장된 함수로 나타날 때 $c_1{\phi}_{00}+c_2{\phi}_{41}$가 포함될 수 있는 원뿔형 공간을 만들고 사상을 정의하였고 이 사상의 역(逆)사상의 해의 존재여부에 따라서 빔방정식의 존재하는 해의 개수를 찾는데 이용하였다.

This study analyzed Korean representative ideology to establish a service philosophy. As a follow - up study of the service philosophy consistency study of the Korean original idea, we searched for the coherence as the philosophy of the service age in the Korean representative ideology. The basic structure and operation model of service philosophy are presented, and the service philosophy of major korean ideology is derived. The philosophy of service can be presented by the structure of service and the operation of service. The essential characteristics of the service are relationship, interactivity, horizontality, and harmony, and the service structure that reflects this is the coexistence of products and services. Based on the discussion on the structure and operation of the service philosophy, the service philosophy synthesis of Korean representative ideology is presented. From the Silla era to the Koryo dynasty, the essence of Korean Buddhism thought is in line with the service philosophy, and it was found that Toegye and Yulgok to Dasan's thoughts are also consistent with service philosophy. In the future, we need further studies to refine the structure and operational principles of the service philosophy and to develop it into a big idea. In addition, it is necessary to follow up the service philosophy of Oriental representative ideology centering on Chinese and Indian philosophy. Ultimately, it is necessary to establish a service philosophy as the main philosophical thought and to establish a service philosophy as a desirable future economic and social philosophy.

오직 조선후기 문화연구에만 매달려온 정옥자 교수의 이번 저서는 '조선중화'를 화두로 삼는다. 우리 민족의 독창성을 확인시켜주는 사상사 연구가 부족한 가운데 정교수의 연구는 국가 양란을 극복하고 조선 고유의 문예부흥을 이끌어낸 정신의 힘이 '조선중화'에 있었음을 밝혀내고 있다.

Seongdeokdaewang-Shinjong, the 29th National Treasure, is highly valuable as a study material in various aspects including the histories of ideology, Buddhism, politics, art-craft, Chinese character study, calligraphy, epigraphy and so on of the mid-time of Shinra. Compared with the people's interest in the Shinjong, however, the studies on the words carved on it have not been yet deepened. Such studies have not been yet overcoming the phase of decoding and translation of the words. Today, it is required to analyze and study the words systematically. This article starts with such critical mind. That is why the subtitle of this article is Research on the Background of Thoughts considering that this study must be followed by its 2nd study. This study has totally reviewed the decoding and annotation works that have been done so far. Byeonryeomun (騈儷文: a writing style of Chinese character) has been also studied on its written patterns. As a result, approximately 20 problems have been found and corrected. Especially, such key phrases as '工匠?模' and '日月?暉' have been translated in a new way to spotlight the importance of translation of the carved words. The words carved on the Shinjong are highly valuable to study in the aspect of ideology history. The words fully show not only Buddhist thoughts, Confucian thoughts and Taoist thoughts but also Korea's own unique thoughts, which are all melted in the words without any obstacle to each other. In general, they are highly philosophical words. The words are unique especially in the aspect: They give a meaning to the Shinjong based on the keyword Won-Gong (圓空: circle and empty) and suggest the key point of Buddhist thoughts and governing philosophy altogether. That is, they imply that King Seongdeok's political ideology and governing principle are connected to Pungryudo (風流道), Korea's own unique philosophy. This implication is key evidence that makes it possible to trace the context of transmission of Pungryudo. You should not miss also the phrases implying that there was a big argument between reform group based on Confucian thoughts and conservative group based on Korea's own unique thoughts.

This research aimed at investigating Kim Gyoshin's recognition on Korean traditional ideology and harmony of Christian idea and traditional idea through the writing and diary in "Bible Joseon". Kim Gyoshin expressed positive interest in Korean traditional idea and traditional religion, and intended to localize Christian belief through communicating with them. He expressed infinite respect for national cultural asset of Buddhism, intending to research Korean Buddhism. He paid utmost attention to Confucianism among traditional ideas. He had a strong affection for learning(好學), benevolence(仁義), conscience(良心) of Confucianism as patriotic character. He calmly practiced caution and solitary(愼獨) of sincere(誠), solemnity(敬) of Confucianism through his life, however he chose Christian belief by accepting atonement belief realizing human sinful nature fundamentally inherent in human being. He personally respected Confucius and lived after the model of him, however he searched the spirit of life to renew the people from Christianity. Academically, he respected Confucius, and believed in Jesus in religion. He highly evaluated the attitude of patriot(志士), which highly regarded the academic attitude of learning(好學) and benevolence(仁義), in this regard, criticized blind and non-intellectual belief. He had an open attitude toward Korean traditional idea with no prejudice. As human individuals have their own inherent moral value, he viewed that each people would have their inherent ethnicity and mission. He considered that Korean Peninsula where contradiction and yoke of the world history are inherent is the center of East Asia that would purify injustice of the world. He viewed that Korean people had owned their original good heart[仁] even before Buddhism and Confucianism had been transmitted to the country. He determined that Korean people were good people, who received goodness from the heaven. However, while Uchimura created Japanese style Christianity by adapting Japanese knighthood to Christian idea, Kim Gyoshin lacked sharp critical mind regarding how to establish Korean style Christianity by adapting which of Korean traditional idea to Christian idea.

개인의 체질에 맞춰 의학적 행위를 시행하는 사상의학은 우리나라 고유의 전통의학으로 가치를 인정받고 있다. 이러한 사상의학에서 가장 중요한 것은 사상체질의 정확한 분류이다. 본 논문에서는 기존의 사상체질 분류 방법인 용모사기, 체형기상, QSCCII, 체질침 등이 임상의들의 직관에 의해 행해지고 있다는 문제점을 해결하기 위해 사상체질 분류의 정량화 및 객관화를 위한 연구를 수행하였다. 이를 위해 본 논문에서는 음성 신호 분석에서 발생하는 정보의 출력값에 의해 사상 체질을 분류하는 방법을 제안하였다. 이를 위해 40대 이상의 장년기 남성을 대상으로 사상체질 전문의의 진단표에서 뚜렷한 특징을 보유하고 있는 집단군을 구성하고 이들의 음성 특성을 분류하여 음성학적 요소를 추출하고자 한다. 또한 출력된 결과값을 토대로 체질 집단별 차이점과 유사성을 분류하여 사상 체질 분류를 행하였다.
