In this paper, we experimented with speaker change detection that uses a statistical method for NOD (News On Demand) service. A specified speaker's change can find out content of each data in speech if analysed because it means change of data contents in news data. Speaker change detection acts as preprocessor t hat divide input speech by speaker. This is an important preprocessor phase for speaker tracking. We detected speaker change using GLR(generalized likelihood ratio) distance base division and BIC (Bayesian information criterion) base division among matrix method. An experiment verified speaker change point using BIC base division after divide by speaker unit using GLR distance base method first. In the experimental result, FAR (False Alarm Rate) was 63.29 in high noise environment and FAR was 54.28 in low noise environment in MDR (Missed Detection Rate) 15% neighborhood.

고려시대 요(遼)⋅송(宋)⋅금(金)⋅원(元)과의 의료 교류 -‘중국의학’ 중심의 시각에 대한 재검토-

In the most common research perspective, Korean pre-modern medical history has been explained as the ‘history of Chinese medicine’. If we approach medical care during the Koryo Dynasty from the perspective of the ‘history of Chinese medicine’, we can see that China was in the center and Korea was in the periphery. From this perspective of the center-periphery theory, it has been argued that ‘Chinese medicine’, which originated in China, always had an influence on the Koryo Dynasty, and that the scope and direction of its influence were comprehensive and one-sided. Therefore, this article specifically traced the exchange of medicinal materials, medical personnel, and medical knowledge between Koryo and Liao, Song, Jin, and Yuan. It was to confirm whether the perspective of the ‘history of Chinese medicine’ corresponds to the historical facts during the Koryo Dynasty. The available records show that the medical exchanges between Koryo and various Chinese countries were intermittent, not consistent. Moreover, the medical care method of one country was accepted selectively according to the needs of each country rather than as a whole. In addition, the flow of exchange developed in both directions, not in one direction. In other words, many countries in East Asia, including Koryo, were actors whose influences reached each other. It was not a structure in which the hypothetical political body called ‘China’ was always located in the ‘center’ and permanently supplied ‘Chinese medicine’ to Koryo while placing neighboring country in the ‘periphery.’ Therefore, the concept of ‘Chinese medicine’ does not have theoretical consistency, and it is insufficient to explain both the reality of pre-modern medical exchanges and the medical system of each country in East Asia. In order to fully explain the traditional medicine of East Asia, a new concept and a logical structure that go beyond the concept of ‘Chinese medicine’ are needed.

조선초기 의료진흥정책의 전개: 통유론(通儒論)과 직분론(職分論)의 대립과 절충

In this article, I examined the medical policy of the early Joseon period. The most important issue in the medical field shortly after the founding of Joseon was who would be responsible for medical practice, such as the establishment and implementation of medical policy, medical learning, and patient treatment. The founding forces of Joseon, who witnessed the problems of medical care at the end of Goryeo, educated the young people of the Yangin (良人) class and instated the current literary officials into medical affairs. Subsequently, under the reign of King Sejong (世宗), the medical learning officer program (醫書習讀 官) was conducted. The program was a system for training medical professionals by intensively educating the young people of the ruling class. This position to train medical professionals at the national level can be called a well-informed Confucianist theory (通儒論). The position of this theory that Confucian scholars should be fluent in all fields is also seen in the Chilhak (七 學, seven schools) under the reign of King Sejo (世祖). The well-informed Confucianist theory was strongly opposed by the Yangban(兩班) class, including current officials who promoted the discrimination theory (職分論). They argued that everyone has a fixed position, and that the medical bureau was the position that professional medical personnel were in charge of. These two positions were challenged throughout the 15th century until a compromise was reached. The compromise was that the ruling class would be in charge of the supervision of the medical bureau and a part of the medical education, while professional medical personnel would be in charge of the practice of medical care such as patient treatment, medical book compilation, and medical profession.

This article deals with the operation and development of the medical learning officer program. In particular, I tracked the activities of 25 medical learning officers, and in this article, the core ruling elite, the general running class, and the medical learning officer’s positions are reviewed. The medical learning officer program was a system for training the ruling class as literati physicians and appointing them as medical officers. The program began when Lee Hyo-ji and others were made to read medical textbooks in the third year of King Sejong’s reign (1421), and later, the present civil officers were transferred to the position of medical learning officers. The medical learning officer program was strengthened throughout the 15th century and included as a regulation in King Seongjong’s legal book, Gyeonggukdaejeon (經國大典). According to this Act, there were 30 medical learning officers who had been appointed alternately to the primary posts for salary payment. They had to learn medical textbooks such as Injejikjibang (仁 齋直指方) and Chandomaekgyeol (纂圖脈訣). The medical learning officer’s mission was to operate the medical system as a whole, including medical textbook research, medical education, compilation of medical textbooks, and treatment of patients. By the late 15th century, however, the medical learning officer positions were neglected. The idea that the medical post was not a major post for the ruling class was gradually reinforced. The position of the founding forces of Joseon and the kings of Early Joseon who drafted and implemented the medical learning officer program was a well-informed Confucianist theory, and the general ruling class position that regarded the medical post as the post of professional doctors was discriminatory. The medical learning officer program was already at its peak under the reign of King Seongjong. The program rapidly declined after King Yonsangun, when the ruling class was no longer interested in the medical learning officer program.

Recently many researchers contributed to the understanding of Quality Control System, but the use of economics in the design of quality assurance system is limited in treatment of the relationship between the average incoming quality level (or average process quality level) of the incoming lot and the average outgoing quality level of this lot. In this study, a traditional concept of sampling inspection plan for the quality assurance system is extended to a consideration of economic aspects in total production system by representing and analyzing the effects between proceeding and succeeding production process including inspection process. This approach recognizes that the decision at each manufacturing process (or assembly process), is to be determined not only by the cost and the average outgoing quality level of that process, but also by the input parameters of the cost and the incoming quality to the succeeding process. By analyzing the effects of the average incoming and outgoing quality, manufacturing or assembly process quality level and sampling inspection plan on the production system, mathematical models and solution technique to minimize the total production cost for a general product manufacturing system with specified average outgoing quality limit are suggested.
