We propose a singnal processor that demodulates the output from an interferometeric sensor at high seed. It is a modified version of the ADPT(Advanced Digital Phase Tracking) that was developed to measure the phase difference in the interferometer with high resolution. The implemented signal processor was turned out to have a speed of 44 mrad/㎲, which is good enough to measure the vibration or voice signal with the maximum phase shift of π/4 rad.

자발성 신파열은 외상 혹은 수술 등의 병력 없이 신장 피막 혹은 신장 주위 혈종이 자발적으로 발생하는 드문 질환으로, 원인으로는 요로 결석[1], 결핵, 신우신염, 신농양 같은 감염성 질환이나[2] 신장의 종양 및 신장 이식 수술 후[3], 후천성 낭성 신환[4] 등이 관련이 있다. 그 중 복막 투석 환자에서 낭성 신질환에 의한 자발성 신파열은 국내 보고가 있었으나 요로감염에 의한 자발성 피막하 혈종을 동반한 신파열은 문헌 보고가 없었다. 저자들은 요로감염으로 진단된 환자에서 피막하 혈종을 동반한 신파열 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

For a large scale civil and architectural structures, mainly steel, concrete and aluminum have been used and weight and corrosion of materials became a major concern. Designing with composite materials is very much complicated. Simple classical theory may yield good results for selecting "initial" sections for preliminary design. D.H. Kim proposed to use the quasi-isotropic constants by Tsai for the preliminary design of the composite primary structures for the civil construction. Also he made simple equation using correction factor. In this paper, the simple formulas developed by D. H. Kim to obtain "exact" values of the natural frequencies of [ABBCAAB]r laminate are compared with reinforcing fiber orientations, are compared with nastural frequencies of bean. This work can be a guideline to obtain data in many other cases.

Objective : This study was performed in order to evaluate the effect of bee venom therapy on rheumatoid arthritis by randomized controlled double blind method. Method : RA patients were recruited and divided into an experiment group and a control group by random selection. As a double blind test, the experiment group was treated with bee venom injection on acupoints, and the control group was treated with normal saline injection on acupoints twice a week for 8 weeks. Tender joint count, swollen joint count, morning stiffness, pain, health assessment questionnaire, ESR. and CRP were estimated and analyzed at baseline, and at 1 month and 2 months after bee venom therapy Results : Compared to the control group, the experiment group showed significant decrease in tender joint count swollen joint count, morning stiffness, and health assessment questionnaire after 2 months. Pain, ESR and CRP showed significant decrease in the experiment group after 1 & 2 months. Conclusions : These results suggests that bee venom therapy could be an effective method in the treatment of patients with rheumatoid arthritis.

:Watermelon (Citrullus lanatus) is an important vegetable crop in the world and contains various health promoting compounds including many antioxidants such as lycopene and beta-carotene. Genetic diversity of cultivated watermelon is very narrow, which is one of major factors limiting the improvement of watermelon breeding program. Gummy stem blight (Didymella bryoniae (Auersw.)) is one of the most destructive diseases and causes crown blight, defoliation and fruit rot, resulting in severe production loss in watermelon. Single nucleotide polymorphisms (SNPs), important molecular markers for genetic studies are frequent sequence variation in the plant genome. This study was performed to develop SNP markers related to gummy stem blight resistance from three watermelon lines, one susceptible and two resistant to gummy stem blight. Of them, 22 SNP primers which were sequence information on SNPs derived from comparing a resistant and susceptible line was used for high resolution melt analysis. A total of 14 candidate SNP primers were detected melt temperature difference. These SNP primers can be useful for developing disease resistance-related markers and, therefore, beneficial to watermelon breeding program.
