판소리는 극적인 어느 한 줄거리의 이야기를 창자와 고수가 같이 하여 소리 아니리 발림 등으로 표현하여 청중을 웃기고 울리는 공연적인 성악곡이다. 판소리의 예술세계에서 가장 깊은 내면세계와 미학적인 접근을 위해서는 음악적 관점에서 접근해야 한다. 하지만 음악적 기록이 전무한 판소리의 음악적 연구는 실제 소리의 채보에 의한 분석 연구가 필요한데 그 첫 장벽인 채보의 방법론적 검토가 없이 이루어진 주관적인 작업은 보편적인 설득력을 얻기에 부족하다. 우리나라의 전통음악은 전승방법이 서양음악과 달라서 음악의 기준이 되는 악보로써 전승되지 않고 구전으로 이어져 왔다. 따라서 채보에 대한 방법론적 연구는 판소리 뿐만 아니라 산조, 민요 가곡 등 구전으로 전통을 이어온 우리나라 전통 음악을 기술하고 분석하기 위해서 가장 먼저 해결해야 할 문제이다.

Confucius made endless thoughts on such themes as enlightening for the internal value of human, how to draw out such value and how to make personal relationship in order to overcome the chaotic Chun-qiu age. The spirit of 'Harmony but not Sameness' stated by Confucius passes us the theoretical meaning for making a good relationship with the others, which is realization of Benevolence. The spirit of 'Harmony but not Sameness' pursues moral, public and golden-mean value. This pursuit is made to look for harmonization and coexistence in personal relation, community based relation and, furthermore, relation with the nature, so that a great man is an entirely-good person who has realized the spirit of 'Harmony but not Sameness'. The spirit of 'Harmony but not Sameness' throws to us many issues to think of for the social unity, 'living together', which is the central theme of today. The objects for which the 'living together' shall be embodied are the minor groups of our society and those who are relatively expelled from the power and benefit including multi-culture based families, north Korean refugees and etc. Such open mind for harmonization and coexistence gives us, furthermore, another important issue to think of also in the matter of environment that includes the ecosystem and the entire nature.

It is widely recognized that human beings have moral responsibility for their actions because they have free will to choose and control their acts. Unlike natural phenomena, however, human acts cannot be interpreted with simple, visible ones. Human acts are quite different from natural phenomena because they come about through a number of complicated, invisible phases taking place in our mind. In addition, human actions are under the influence of internal and external factors. Those various internal and external factors are divided into four sectors as follows; (1) the factors that can fall under control of our free will, (2) the factors in the interim phase that could come under our control, (3) the factors that are partially determined that we cannot choose or control over, and (4) the factors that completely determined, and can't be chosen or controlled. we have to pay attention to the fact that we can choose or control the internal and external factors that influence human action. However, there are still factors that are impossible to choose or control with our will. So it is highly unreasonable to hold accountable for actors by means of the factors that can't be chosen or controlled. Hence, the society should be also accountable for the acts of actors influenced by heredity and environment. For this, Politics should affect the external, undesirable, and uncontrollable factors beyond actors power. Education has to exert its influence over the internal and genetic factors by instilling sound values in human mind, too. It is because happy and desirable future will be possible by giving equal opportunities to us including the youth.

The main concern of classical Confucianism, which has Kongzi as its main thinker, is how one can attain moral perfection. In this respect, all of the Confucian teachings can be characterized as an attempt to expound the nature of sages or gentlemen who are believed to attain moral perfection. In Confucianism, de 德 (moral virtue) refers to moral principles or the attributes of things, and it also signifies moral qualities and abilities of humans which are believed to be bestowed by the moral source. Kongzi substantiated the details and practical methods of de, through his teachings of ren as its internal principle and li as its external form. in this way, he put a special emphasis on moral practicality of de. To study Kongzi's practical moral teachings focusing on de can be understood as a reflection on current educational issues.

A shape optimization problem is formulated to determine the optimal position of heating lines in a compression molding die. The objective of the problem is that the cavity surface would be maintained by a prescribed uniform temperature. A boundary integral equation for the sensitivity of the temperature in terms of hole position is derived using the method of shape design sensitivity analysis. The boundary element method is employed to analyze the temperature and sensitivity field of the die. The sensitivity calculation algorithm is incorporated in an optimization routine. To demonstrate a numerical implementation, an example problem arising in thermal design of a compression molding die is dealt with, showing that the number of heating lines chosen for the die strongly affects the ultimate uniformity of the cavity surface temperature.

유압 Vane pump는 carming, rotor, vane에 의하여 둘러싸인 공간체적이 rotor의 회전과 함께 변화하면서 pump 작용을 한다. 즉 공간체적이 증가하는 동안은 유압이 저압으로 되어 흡입구에서 유압유를 흡입하고 vane의 존환점 (vane이 가장 많이 출한 점)을 지나면 공간용적이 감소하여 유압류는 고압으로 될 수 있도록 되어있다. 이때 vane은 관성력과 점성력 그리고 유압류의 압력에 의한 힘으로 vane 선단이 캠링의 내면에 밀착되어 회전하도록 되어있다. 유압 vane pump 베인 선단부의 윤활문제와 관련된 지금까지의 연구로서는 Hibi 등에 의한 압력평형형 베인모터, W.D Beck, T.C Edwards에 의한 베인형 콤푸렛셔 Ujiie 등에 의한 베인형 진공펌프, Ueno 등에 의한 가변용량형 베인펌프의 마찰특성에 관한 연구 및 베인 이간 현상에 관한 실험적 연구가 있다. 그러나 이와 같은 연구들의 베인과 캠링 슬라이딩 부분에 관한 취급들은 베인선단 슬라이딩 부분에 가해지는 변동가중이 불명확했기 때문데, 단순히 슬라이딩 부분의 면적이 작다는 이유로 단성유체 윤활상태일 것이라는 확정을 하였을 뿐, 실제적으로 어느 정도의 윤활 상태를 파악하기 위하여 회전하는 vane의 가학적인 거동을 확실하게 규명하고자 함이 본 연구의 목적이다.

본 논문에서는 입력음성신호로부터 음소간의 경계를 찾는 문제를 풀기위해 재귀적인 방식으로 EM 알고리즘을 적용한다. 즉, 예상되는 두 끝점 사이의 부분을 현재의 프레임 n 이라고 하면, 그 전 프레임 n-1 에서 구해진 끝점이 주는 정보와 그 끝점으로부터 이어지는 음성샘플로부터 현재 프레임의 끝점을 구한다. 또한 현재의 프레임 n 에서 끝점을 추정해 내면, 그 추정한 끝점과 그 점 이후에 이어지는 음성샘플값으로부터 다음 프레임 n+1 의 끝점을 구한다. 이러한 방식을 재귀적인 음소분리 방식이라고 한다. 그리고, 각 프레임에서 끝점을 구하기 위해서는 끝점의 좌표를 추정해야 할 파라메터로 하고, 그 주변의 음성샘플 값을 관찰 값으로 하여 EM(Expectation and Maximization) 알고리즘을 이용한다. 이 EM 알고리즘을 이용한 재귀적인 음소분리 방식을 실제 음성 DB 로부터 음소쌍을 추출하여 테스트 했을 때 약 5 회의 EM 반복 후에 경계간으로 수렴함을 볼 수 있었다.

Statement of problem: The interest in all-ceramic restorations has increased as more techniques have become available. With the introduction of machinable dental ceramics and CAD/CAM systems there is a need to evaluate the quality levels of these new fabrication techniques. Purpose: This study is to evaluate the crown fidelity(absolute marginal discrepancy and internal gap) of various zirconia-based all-ceramic crowns fabricated with different CAD/CAM(computer-assisted design/computer-assisted manufacturing) systems and conventional cast metal-ceramic crowns. Material and methods: A resin tooth of lower right second premolar was prepared. After an impression was taken, one metal master die was made. Then 40 impressions of metal master dies were taken for working dies. 10 crowns per each system were fabricated using 40 working dies. Metal-ceramic crowns were cast by using the conventional method, and Procera, Lava, and Cerec inLab crowns were fabricated with their own CAD/CAM manufactruing procedures. The vertical marginal discrepancies and internal gaps of each crown groups were measured on a metal master die without a luting agent. The results were statistically analyzed using the one-way ANOVA and Tukey's HSD test. Results: 1. Vertical marginal discrepancies were $50.6{\pm}13.9{\mu}m$ for metal-ceramic crowns, $62.3{\pm}15.7{\mu}m$ for Procera crowns, $45.3{\pm}7.9{\mu}m$ for Lava crowns, and $71.2{\pm}2.0{\mu}m$ for Cerec inLab crowns. 2. The Internal gaps were $52.6{\pm}10.1{\mu}m$ for metal-ceramic crowns, $161.7{\pm}18.5{\mu}m$ for Procera crowns, $63.0{\pm}10.2{\mu}m$ for Lava crowns, and $73.7{\pm}10.7{\mu}m$ for Cerec inLab crowns. Conclusion: 1. The vertical marginal discrepancies of, 4 crown groups were all within the clinically acceptable range($120{\mu}m$). 2. The internal gaps of LAVA, Cerec inlab, and metal-ceramic crowns were within clinically acceptable range except Procera crown($140{\mu}m$).

The implicit association test (IAT) measures implicit attitudes of participants and is regarded as an effective method for expecting future behaviors. Based on the IAT, this study aimed to answer the question, whether implicit attitudes of an individual about creativity have any kinds of impact on global perception, which might be important for a creative process. In the experiment, participants were presented words, which were associated with one of four categories, while one attitude category (creativity /practicality) and one evaluative category (good/bad) were always paired together either on the left side or on the right side of the computer screen. After completing the IAT test, participants were led to fill out a questionnaire to assess explicit attitudes toward creativity and practicality. Then they conducted the navon task, in which they had to find one of two letters, 'F' or 'H', which were presented either as a local form or as a global form. Finally, the participants had to write down as many untypical functions of an object as possible. The results showed that not the scores of explicit attitude scores but the IAT scores correlated with the reaction time of global perception. The global perception was faster in the participants with the low IAT scores than the local perception. Compared to this, the global perception benefits disappeared in the participants with the high IAT scores. Additionally, more creative ideas about the functions of the object were listed in the group with the lower IAT scores. Implications of the role of implicit attitudes about creative processes are discussed.
