본 논문은 wavenet을 이용하여 음성 신호의 대역폭을 확장하는 새로운 모델을 제안한다. 기존의 대역폭 확장은 주로 주파수 영역에서 진행되며, 확장 대역의 주파수 크기는 높은 성능으로 복원하지만 위상 정보를 정확히 복원할 수 없다는 문제점을 가진다. 이를 해결하기 위해 wavenet 모델을 기반으로 시간 영역에서 저대역과 고대역의 상관관계를 이용하여 고대역 성분을 생성하도록 한다. 제안하는 방법은 모든 동작을 시간 영역에서 수행하며, 제안 방법으로 생성한 고대역 성분이 원음의 고대역 성분과 유사한 것을 확인하였다.

Objectives: The aim of this study was to evaluate the effect of immune-enhancing oral supplement including glutamine, arginine, and leucine on the immunological change after gastric cancer surgery. Methods: Patients undergoing subtotal gastrectomy were randomized to control and study group. Study group received immune-enhancing supplement including glutamine, arginine, and leucine (Curact®) and control group received placebo supplement including same calories dextrose. Postoperative supplements were started at the postoperative day (POD) 7th and continued for 3 weeks after discharge. Immunological data were collected included count of White blood cell (WBC), C-reactive protein (CRP), immunoglobulin (Ig), CD4, and CD8 at preoperative, POD 5th and POD 28th, respectively. Nutritional data were collected included albumin, prealbumin, cholesterol, and patient-generated subjective global assessment (PG-SGA). Results: 60 patients were randomized, of whom 15 patients were dropped and 45 patients were analyzed (control 23 patients, study 22 patients). Characteristics, nutrition and immune related factors at preoperative and POD 5th were not different between two groups. At POD 28th, mean CRP and count of WBC were significantly lower in study group, and mean level of Ig M was significantly higher in study group than the control group (137.9 vs. 108.7, p=0.021). Ig G, CD4 and CD8 tended to be preserved in the study group, however, there was no statistical difference between two groups. PG-SGA became significantly worse after surgery in both group, however there was no difference between two groups. Conclusions: Immune-enhancing oral supplement might have positive effect on immune preservation and decreasing inflammation after gastric cancer surgery.

With the advent of increasingly competitive global market, the importance of formulating an effective international marketing strategy has been received significant academic attention and research interest in the international business literature. Focusing on the differences of product strategies to firm nationalities in international markets, we conduct a cross-national perspectives in Asian context. We collected survey data from Korean and Japanese exporters. 216 usable questionnaires were obtained in Korea, and 117 usable questionnaires were obtained in Japan. Understanding the nature of international marketing strategies employed by Korean and Japanese firms as well as its effects may provide a useful reference point for researchers in international business and exporters from other emerging countries in Asia.

대학 신입생의 기초 학력수준을 바탕으로 대학 교양수학의 내용을 재편하며, 특별히 생명과학분야를 전공할 학생들에게 실질적인 도움을 줄 수 있는 수학 교과모형의 방향을 제안한다. 이를 위해 외국에서 개발 운영되고 있는 다양한 형태의 강의 모형을 조사하여, 우리 학생들 수준에 적합하며 또한 전공에 필요한 수학내용의 선별절차를 걸쳐 강의내용과 교재의 개발 방향을 제시한다. The biological science is rapidly expanding with an increased need for more quantitative analysis of the data. And mathematics are becoming more important to research in biological science. However many undergraduate students think that biology is a natural science which is not related to mathematics. In this work, we study a curriculum renewal across the college calculus for undergraduate students majoring biological science. We deal with 3 questions. First, we do a case study about universities across the world that has special calculus classes for students who major biological science. Second, we distinguish contents of mathematics which are most useful for biological science. Third, we investigate how to develop university calculus course in connection with highschool mathematics curriculum.
