We present a pre processing system for the Atmospheric Infrared Sounder (AIRS) sounding suite onboard Aqua satellite. With its unprecedented 2378 channels in IR bands, AIRS aims at achieving the sounding accuracy [s1]of a radiosonde (1 K in 1-km layer for temperature and 10% in 2-km layer for humidity). The core of the pre p rocessor is the International MODIS/AIRS Processing Package (IMAPP) that performs the geometric and radiometric correction to compute the Earth's radiance. Then we remove spurious data and retrieve the brightness temperature (Tb). Since we process the direct-broadcast data almost for the first time among the AIRS directbroadcast community, special attention is needed to understand and verify the products. This includes the pixel-to-pixel verification of the direct-broadcast product with reference to the fullorbit product, which shows the difference of less than $10^{-3}$ K in IR Tb.

We know paranasal sinusitis is one of the most common disease in the field of otolaryngology. Especially in the case of chronic paranasal sinusitis, patient is sufferred from recurrence. So we prescribed Bojungikgitang(補中益氣湯) to the patients who were suffered from chronic paranasal sinusitis, and we witness some noticeable improvement. Here are the findings of my experience 1. The addition and subtraction temperament drugs of Bojungikgitang(補中益氣湯加減方) are effective to the patient of chronic and feeble paranasal sinusitis by the effect of removing wind(祛風), unnecessary metabolite(祛痰), and draining pus(排膿) and strengthening digestive organs(健碑) and enriching the lung yin(益肺陰) and alleviation of pain(止痛). 2. In the symptom of chronic paranasal siunutitis, nasal obstruction, postnasal drip, sputum, headache were quick to disappear, and dysosmia, internasal polyp, etc got better slower. 3. The most quick improvement appeared within two weeks and most symptoms improved within one month, and disappeared within two months.

김성범,Kim, Seong-Beom 한국전자통신연구원 1983 전자통신 Vol.5 No.1

전자교환기의 통화로부분에서 free인 통화로를 선택 접속시켜주는 방법은 통화로의 구성과 기능에 따라 달라진다. 본 논문에서는 일반 전화뿐만 아니라 TV전화, 데이타전송, 비데오텍스(Videotex),스테레오방송 등을 교환 접속시켜 주는 광대역용 전자교환기(Wideband switching system)의 교환접속망(Switching matrix)을 효과적으로 구성하여 통화로 선택이 전교환접속망에 걸쳐 고루 분포될 수 있는 방법을 제안하였다. 그리고 그에 따른 pathsearching simulation program을 작성하여 실예를들어 설명함으로써 본 논문에서 제안한 통화노선택방법의 유용성을 보였다. The pathsearching method in switchingmatrix of an electronic switching system depends upon the structure and function of the system. In this paper, an efficient way to construct the switching matrix and a pathsearching method under the full distributed traffic theory in an wideband switching system, which can control not only normal telephone call, but also TV telephone, data communication, videotex and sound, is proposed. And the effectiveness of the method is shown through an example of the pathsearching simulation program.

In the age of puberty or 20-30th young people who are sensitive to outward appearance, acne is serious problem at beauty and has social and psychological influence on that people. So this experiment is carried out for test whether the addition temperament drugs of Yungyopaedock-san(YP) have an anti-inflammatory effect and have suppression effect on immunocyte in the state of inflammation which induced by acne. The results was as follows. 1. YP has suppress inflammatory reaction induced by carageenan. 2. YP has suppress increasing activation of abdominal cavity macrophage in the carageen and zymosan induced inflammation. 3. YP has suppress increasing activation of spleen cell in the carageenan and zymosan induced inflammation. Based on the above result, YP was improved its suppression effect to the inflammatory reaction through the suppression of spleen cell and macrophage activation. So we concluded that YP is prospected as a anti-inflammatory agent to cure inflammation induced by ance.

Objective : Angiogenesis induced by hypoxia and inflammation are an essential process of solid tumors and psoriasis. We researched the HIF-1 ${\alpha}$ (hypoxia inducible factor 1 alpha), VEGF(Vascular Endothelial Growth Factor), survival related PI3K-Akt, and inflammation related COX-2 protein expressions to get the information of the mechanism and effects of Rehmannia glutinosa in HepG2 and HaCaT cell lines. Method : To investigate the roles of the Rehmannia glutinosa extract, we performed MTS assay and western blots using HaCaT cells and HepG2 cells. HaCaT cells and HepG2 cells were treated with $50{\mu}g/ml$ and $100{\mu}g/ml$ Rehmannia glutinosa extracts. After 4hrs, HaCaT cells were treated with IGF-II protein for 24hrs and HepG2 cells were treated with $CoCl_2$. Results : 1. We could ohserve that the reduction of the protein level of HIT-1 ${\alpha}$ induced by IGF-II in HaCaT cells. 2. We Could ohserve that the decreased PI3K-Akt and COX-2 expression level by Rehmannia glutinosa extracts treated in HaCaT cells independently ith ERK1/2. 3. We could observe that the reduction of the protein level of HIF-1 ${\alpha}$ induced by $CoCl_2$ in HepG2 cells. Conclusion : These results suggest that Rehmannia glutinosa extracts contributes to the anti-survival pathway and anti-inflammatory activities. Also, we could assume that Rehmannia glutinosa act as anti-inflanmmatory or anti-hypoxia agents via reduction of COX-2 and HIF-1 ${\alpha}$.

Cholera toxin, which has been frequently used as mucosal adjuvant, leads to an irreversible activation of adenylyl cyclase, thereby accumulating cAMP in target cells. Here, it was assumed that β2-adrenergic agonist salbutamol may have modulatory functions of immunity induced by DNA vaccine, since β2-adrenergic agonists induce a temporary cAMP accumulation. To test this assumption, the present study evaluated the modulatory functions of salbutamol co-administered with DNA vaccine expressing gB of herpes simplex virus (HSV) via intranasal (i.n.) route. We found that the i.n. co-administration of salbutamol enhanced gB-specific IgG and IgA responses in both systemic and mucosal tissues, but optimal dosages of co-administered salbutamol were required to induce maximal immune responses. Moreover, the mucosal co-delivery of salbutamol with HSV DNA vaccine induced Th2-biased immunity against HSV antigen, as evidenced by IgG isotypes and Th1/Th2-type cytokine production. The enhanced immune responses caused by co-administration of salbutamol provided effective and rapid responses to HSV mucosal challenge, thereby conferring prolonged survival and reduced inflammation against viral infection. Therefore, these results suggest that salbutamol may be an attractive adjuvant for mucosal genetic transfer of DNA vaccine.

This paper deals with the broadband electromagnetic emission test of a hybrid electric vehicle. The hybrid electric vehicle's powertrain system consists of an internal combustion engine and an EV traction motor. Depending on the SOC of the traction battery, these modes change automatically in the running state. The Korea electromagnetic compatibility regulations of KMVSS and UN WP.29 stipulated the evaluation method of hybrid electric vehicles. This study analyzes and compares two test results: internal combustion and electric motor mode. Some problems of test conditions are described and an improved test method is proposed for measuring broadband emissions of a hybrid electric vehicle. As a result, we expect this paper to be used as a consideration for improvement when test specifications are revised in the future.

In recent years, the structural shock response to UNDEX (UNDerwater EXplosion) has been studied as much, or more, through numerical simulations than through testing for several reasons. Very high costs and sensitive environmental concerns have kept destructive underwater explosion testing to a minimum. Increase of simulation capabilities and sophisticated simulation tools has made numerical simulations more efficient analysis methods as well as more reliable testing aids. In this study, the main issue is the fluid-structure interaction. Here, appropriate relations between the acoustic pressure on the fluid surface and displacements on the structure surface are formed internally. The analysis was carried out using ABAQUS/Explicit and the results have been visualized in ABAQUS CAE. The shock loading history, acoustic pressure, stress of stand-off point, the velocity and strain energy time histories were presented.
