Small-sized fans for cooling electronic components are usually produced by injection molding in unified form including blade and hub. However, in case of middle and large-sized fans, they deal ill various products with varied numbers of blade or stagger angles after designing a single blade by molding or aluminum die casting. At this occasion, it is necessary to study design method for high-performance axial fans can be operated with various numbers of blades or stagger angle using unique blade for specified conditions. Therefore, the goal in this study is developing a optimal design method which improves performance of axial fans within the large range of operating by single blade.

This paper presents a demosaicking method based on high-order interpolation with parameters. Demosaicking is an essential process in capturing color images through a single sensor-array. Thus, a lot of methods including the Hamilton-Adams(HA) method has been studied in this literature. However, the image quality depends on various factors such as contrast and correlation in color space; existing algorithms depend on test images in use. Consequently, a new test image set was suggested to develop demosaicking algorithms properly. According to previous studies, the HA method shows high performances with the new test data set. In this paper, we improve the HA method using high-order interpolation with parameters. Also, we provide an analysis and formulations for the proposed method. To evaluate our method, we compare our method with the existing methods both objectively and subjectively. The experimental results indicate that the proposed method is superior to the existing methods.

The purpose of this study was to investigate the sodium intake of office workers using 24-hour urine analysis and to analyze the correlation matrix between variables. The sodium intake of the subjects (n = 137), based on a 24-hr sodium excretion period, was male (n = 56) 6072.4 mg and female (n = 81) 5,168.2 mg. Urinary sodium excretion showed significant positive correlation with BMI, frequency of eating out, expenditure of eating out, salty taste assessment and high-salt dietary behavior. Analysis of urinary sodium excretion showed significant positive correlation with intake frequencies of cabbage kimchi, broiled fish, feast noodle and rice with leaf wraps. Based on the results of multiple regression, urinary sodium excretion was found to be related to intake frequencies of cabbage kimchi, broiled fish, rice with leaf wraps and high score of high-salt dietary behavior.

Purpose: The purpose of this study is to report the effect of Korean Medicine therapy to chronic pelvic inflammatory disease. Methods: A 34 years old woman, who suffered from chronic pelvic inflammatory disease was admitted to the OBGY department of Se-Myung University, Je-Cheon. In the beginning of treatment, she had pain and cold in the lower abdomen, dysuria, displeasure of sexual intercourse, etc. She received Korean Medicine therapies such as herbal medicine, moxibustion, acupuncture and got good result from them. Results: As a result, symptoms are remarkably alleviated. Conclusion: The present study suggests that Korean Medicine therapies have significant effect on chronic pelvic inflammatory disease.

본 논문에서는 동적 프로그래밍 스티칭을 이용하여 다수의 이미지를 경계가 보이지 않게 정합하여 고해상도의 이미지를 얻는 방법을 소개한다. 제안하는 방법에서는 수직, 수평방향으로 일정한 간격으로 쵤영한 다수의 지역 이미지와 전체를 촬영한 전역 이미지를 사용해서 각각의 지역 이미지와 전역 이미지의 특징점을 추출하고 이를 매칭하여 호모그래피를 계산한다. 이를 이용하여 정합할 두 지역 이미지간의 호모그래피를 구하고 좌표를 변환한 후 겹치는 영역에 동적 프로그래밍 스티칭 방법을 적용하여 두 이미지를 정합한다. 동적 프로그래밍 스티칭 방법이란 두 이미지를 정합할 때 겹치는 영역의 차이를 계산하고 차이가 가장 적은 픽셀을 경계로 하는 방법이다. 다수의 이미지를 수직방향으로 정합하고 정합된 이미지들을 수평방향으로 정합하여 하나의 고해상도 이미지를 만들 수 있다. 제안하는 스티칭 기법을 적용함으로써 이미지간의 경계가 드러나지 않을 뿐만 아니라 각 픽셀의 세밀한 정보도 유지한 고해상도의 이미지를 획득할 수 있음을 보였다.
