"Jinaik(津液)" is essential nutritious body fluid for human to be alive, and it can be divided various kinds according to it's location, character, and function. Five Fluids -sweat, snivel(mucus), slobber(saliva), tear, spittle(saliva)- are kinds of "Jinaik(津液)", and all of them belong to kidney. They are also related with five organs, such as sweat belongs to heart, snivel(mucus) belongs to lung, slobber(saliva) belongs to spleen, tear belongs to liver, spittle(saliva) belongs to kidney. We can find out five organs' physiological and pathological conditions by means of observations on the Five Fluids. Five organs' function comes out upper seven openings -two eyes two ears, nose, mouth and tongue. The Five Fluids provide all the nutrition upper seven openings need, so they can help for human to hear, see, smell, and taste properly.

In this paper, a respiration measurement method using FMCW signal for off-the-shelf smartphone is presented and investigated. The proposed algorithm transmits FMCW signal periodically instead of transmitting continuously so that one can reduce the power consumption from speaker in smartphone and the algorithm complexity. In order to eliminate the clicking noise generated when transmitting FMCW signal, Tukey window with ${\alpha}=0.01$ is applied to prevent the noise from being heard. An application program for Android OS which can transmit FMCW signal through speaker and record the reflected signals through MIC has been developed. Since the total duration of the signal transmission is set to 20msec per 1 second for the experiments, the power consumption can be decreased by 80% compared to the continuous transmission. It was confirmed that the clicking noise is inaudible as long as a smartphone is located at more than 10cm from ears. In the experiments on a sleeping child, the breathing signal of about 0.27Hz was measured.

초당옥수수의 수확기 분산을 위한 파종기에 따른 적정재식밀도를 규정하기 위하여 경북 경산에서 "Cambella 90"을 흑색 P E. film 피복하여 파종기 4월 1일, 5월 1일, 6월 1일, 재식밀도를 3,500, 4,500, 5,500, 6,500, 7,500주/10a 조건에서 파종하여 생육과 이삭특성 및 상품성 있는 이삭수를 조사한 결과를 하면 다음과 같다. 1. 출아율과 입묘율은 4월 1일 파종기에서 낮았고, 재식밀도 간에는 차이가 없었다. 간장과 착수고는 5월 1일 파종에서 가장 높았으며, 재식밀도가 높을수록 증가하였다. 2. 분얼수는 파종기가 빠를수록, 재식밀도가 낮을수록 증가하였다. 출사기는 파종기가 한 달씩 늦어질수록 각각 15 및 22일 지연되었고, 재식밀도 간에는 차이가 없었다. 3. Brix 당도는 5월 1일 파종기에서 가장 높았고, 재식밀도가 낮을수록 당도가 높았다. 4. 파종기가 늦을수록, 재식 밀도가 증가할수록 이삭장, 착립장, 이삭경, 이삭중이 모두 감소하였다. 착립장과 이삭중과는 정의 상관이 있었으나 파종기가 다를 때는 같은 착립장에서도 이삭중의 변이가 커서 이삭의 품질은 이삭중으로 나타내는 것이 타당하였다. 5. 초당옥수수의 적정 재식밀도는 중품$(200{\sim}300g)$과 상품 (300 g)의 상품성 있는 이삭수를 4,000개/10a를 목표로 하여 4월 1일 파종에서는 낮은 출아율을 고려한 $6,500{\sim}7,500주/10a$, 5월 1일 파종에서는 $5,500{\sim}6,500$주, 6월 1일 이후의 파종에서는 6,500주이었다.

The most recent trend on digital hearing aid is to increase the ratio of signal to noise by directivity or to develop noise reduction algorithm inside DSP IC chip. This paper designed, fabricated and tested a digital hearing aid directivity testing device in which a micro-mouse-like the stepping motor with a speaker rotates around an examinant. Both ears of the examinant were fixed with ITE hearing aids in order to response to receiving sound. The diameter of the directivity testing device was 2 [m] and the micro-mouse was precisely controlled by PICBASIC micro processor.

Donguibogam rearranged existing vast work was established as the medical science laying stress on human body. The contents of this book are divided into internal side of the body as Naekyung pyon. into outer side of the body as Woehyung pyon, into various kinds of diseases except for diseasesin Naekyung pyon and Woehyung pyon as jopbyung pyon, into medical herbs in natural world as Tangaek pyon, and into acupuncture and moxa cautery as Chimgu pyon. The contents in Naekyung pyon are classified into essence, vigor, spirit and blood. dream, vocal fermitus, speech, sap and unsound mucus, five vicera and six entrails, womb, vermin, urine and feces. And the contents in Woehyung pyon are divided into head, face, eyes, ears, nose, mouth and tongue, teeth thoat from upper to lower part of the body.

The intradermal injection of Propionibacterium acnes (ATCC 6919) into the ears of female Sprague-Dawley rats produced a chronic inflammation with the formation of acneiform lesions. Inflammation was characterized by more than four times of ear thickness and 2.8 times of ear weight at day 21. Histologically, massive infiltration of neutrophils, macrophage and lymphocytes, hyperplastic epidermis, comedones containing keratin mass and inflammatory materials were observed. Both ginseng saponin and extract from Korean red ginseng significantly redliced the ear thickness and their effects were similar to that of benzoyl peroxide. Ginseng samples and beneoyl peroxide modified lipid constituents of P. acnesinjected rat ear tissues. Even though no marked histological changes in inflammatory lesions were observed in ginseng-treated ear tissues, Korean red ginseng showed a possibility of reduce in the risk of acne development.

A digital watermarking technique applying psychoacoustic model for audio signal is proposed in this paper. In the watermarking scheme, the pseudo-random bit stream used as a watermark signal is embedded into the audio signal in both speech and music. The strength of the embedded signal is subject to the human auditory system in such a way that the disturbances on host audio signal are beyond the sensing of human ears. The experimental results show that the quality of the watermarked audio signal, in term of signal to noise ratio, can be improved up to 3.2 dB.

This review is concerned with the MP (multipactor) phenomena of the diplexer for RFDU DM of next generation satellite. The MP discharge is serious problems to design RF components in space applications such ase damage of physical structure, performance degradation, and mission failure of the satellite. In this work, we employed the 3D finite element method (FEM) to calculate the critical gap points and adopted ESTEC curve, MP susceptibility zone, to analyze the maximum handling RF power in the diplexer. And this work also recommends that one should design the tx filter of the diplexer which is more wider bandwidth upto the points to escape the ears of the group delay especially the cavity type of RF components in space applications.
