In this paper, we propose a channel normalization method to improve the performance of CMS (cepstral mean subtraction) which is widely adopted to normalize a channel variation for speech and speaker recognition. CMS which estimates the channel effects by averaging long-term cepstrum has a weak point that the estimated channel is biased by the formants of voiced speech which include a useful speech information. The proposed Formant-broadened Cepstral Mean Subtraction (FBCMS) is based on the facts that the formants can be found easily in log spectrum which is transformed from the cepstrum by fourier transform and the formants correspond to the dominant poles of all-pole model which is usually modeled vocal tract. The FBCMS evaluates only poles to be broadened from the log spectrum without polynomial factorization and makes a formant-broadened cepstrum by broadening the bandwidths of formant poles. We can estimate the channel cepstrum effectively by averaging formant-broadened cepstral coefficients. We performed the experiments to compare FBCMS with CMS, PFCMS using 4 simulated telephone channels. In the experiment of channel estimation, we evaluated the distance cepstrum of real channel from the cepstrum of estimated channel and found that we were able to get the mean cepstrum closer to the channel cepstrum due to an softening the bias of mean cepstrum to speech. In the experiment of text-independent speaker identification, we showed the result that the proposed method was superior than the conventional CMS and comparable to the pole-filtered CMS. Consequently, we showed the proposed method was efficiently able to normalize the channel variation based on the conventional CMS.

전통된장 제조방법으로서 원료 혼합비, 메주의 건조시간 및 온도, 메주와 된장의 발효 시간 및 온도, 된장 간장의 분리 여부, 된장 숙성(aging) 시간을 조사하였다. 혈액응고 저해 활성(anticoagulant activity)을 fibrin clotting assay법으로 분석하여 혈액응고 저해활성과 제법간의 상관 관계를 검토하였다. 숙성 기간이 길수록 혈액응고 저해활성이 높게 나타나는 경향을 보였으나 선형적인 상관관계보다는 비선형적으로 양의 상관관계를 갖는 것으로 판단되었다. 이상의 결과를 토대로 혈액응고 저해활성이 높은 2종의 된장시료를 선발하였으며 숙성기간이 180일 이상일 경우 전통된장의 혈액응고 저해활성이 높은 것으로 판단되었다.

우리나라는 오랫동안 인문사회적인 가치가 절대적이고 과학기술적인 가치가 천시되는 문화를 형성하였으므로 비합리적인 전통문화를 개혁하려면 고유문화를 경시하는 것으로 오해를 받곤 하였다. 우리사회의 이런 비합리성과 비능률성을 없애려면 '전국민의 과학화 운동'이 가장 효과적이라고 생각하였다.

전통적으로 농산물은 도매시장을 경유하여 유통되어 왔으며 이 때문에 유통단계가 많고 복잡한 것이 특징이다. 그러나 최근 소매업이 대형화, 체인화되면서 대형 소매업체들이 도매시장을 경유하지 않고 산지에서 직접 농산물을 조달하는 유통경로의 비중이 증가하고 있다. 또한 정부에서 투자하고 있는 농산물물류센터도 새로운 유통경로로서 그 중요성이 높아지고 있다. (중략)

현 CRM(Customer Relationship Management)의 솔루션은 기업 중심의 고객관리, 분석, 협업의 기능으로 그룹화되어 시상을 형성하고 있다. 하지만 다양한 고객의 요구 사항을 충족하기 위해서는 어느 하나의 솔루션으로는 현재의 세분화 되고 다양화 되어지는 고객 관리 프로세스를 충족 시키기가 어렵다. (중략)

This paper examines the characteristics of the traditional education contents that they have preserved and succeeded based on the recognition of 'Dongdo' by the modern intellectuals, and selects the contemporary contents of traditional education which are worthy of modern succession, It is aimed to categorize by classification and to reconstruct the contents accordingly. For this purpose, I will try to diagnose the problems of modern education and explore the possibilities of traditional ideas represented by Confucianism as a solution to solve and solve these problems. In particular, I will examine the positive and negative perceptions of intellectuals about studying abroad since the modern era, and examine what are the meaningful things to avoid and how to reconstruct the contents of traditional education in a modern way. Through this review, I will establish the principles for the modern reconstruction of the contents of the traditional education and finally discuss the parts that should be emphasized in the modern reconstruction of the contents of the traditional education and the composition of the alternative contents.

Just as traditional markets nationwide, traditional markets in Jeju area also face a crisis due to expansion of new distribution channel and price competitiveness of large distribution companies. There are various support programs currently being carried out to prevent all risk factors of the traditional markets as government policies. But, these programs have failed to bring a positive change due to lack of specialized products of the traditional market, lack of systematic marketing and customer management, lack of market vendors' consciousness reformation. The purpose of this study is to prepare political measures to promote the revitalization of traditional markets in Jeju area and overcome these limits. To achieve this, this study analyzed the conditions of traditional markets in Jeju area and presented the specialization of items and service for each traditional market, establishment of growth strategies in connection with tourist industry and reinforcement of marketing competitiveness as measures to create a synergy effect.

웹툰은 한국의 서브컬쳐 산업 가운데에서 단연 주목받는 분야이다. 웹툰 산업의 다양화 속에서 전통적 세계관을 지닌 작품이 작품들이 등장하고 흥행을 하는 것은 주목할 만한 사례이다. 특히 <신과함께>, <쌍갑포차> 등의 작품은 대중성과 작품성을 모두 획득했다고 평가할 수 있다. 이들 작품은 무속의 세계를 작품으로 재현하였다는 점에서 이목을 끈다. 무속적 세계라는 것이 미신으로 치부될 것이 아니라 인간 본위의 삶을 영위하도록 하는데 기여하는 것이라는 인식을 보여준다. 이러한 세계인식이 웹툰이라는 매체를 통해서 재현될 때 작품에 공감하는 것은 우리가 살아가는 세계가 더 나아지기를 희구하기 때문이다. 이를 통해서 전통이 지닌 보편적 가치를 확인할 수 있다.

In the traditional seismic processing, multiple reflections are treated as noise and therefore they are eliminated during data processing. Recently, however, many studies have begun to consider multiples as signals rather than noise for seismic imaging. Multiple reflections can illuminate an area where primary reflections are not able to cover, thus it is allowed that a smaller number of shots and receivers are used for imaging large areas. In order to verify this, surface-related multiples were used for reverse-time migration (RTM), and then we compared the results with conventional RTM images which are generated from primary reflections. To utilize multiples, we separated multiples from whole seismic data using surface-related multiple elimination (SRME) method. Numerical examples confirmed that the migration using multiples can image wider area than the conventional migration, particularly in the shallow subsurface layers. In addition, the migration of multiples could eliminate the acquisition footprints.
