  • The purpose of this study was to investigate the effect of moxibustion heat therapy(Koryo hand acupuncture) on menstrual cramps. dysmenorrhea and ADL. The experiment was carried out during the period from March 24 to April 30, 2003. The subjects in the study were drawn from female students attending two colleges in Chungcheongbuk-do and Kyunggi-do. Of all those subjects. 19 and 14 subjects were assigned to the experimental and the control groups respectively. The moxibustion heat therapy were performed three times a week, subjects were treated twice a time. Data was analyzed using SPSS/WIN10.0 by $x^2$test. Wilcoxon sign rank. and Wilcoxon rank sum test. The result of this study were as follows : 1) After moxibustion heat therapy. the graphic rating score of menstrual cramps was decreased significantly from 7.79(SD=1.22) to 4.47(SD=2.25) in experimental group(z=-3.731. p=.000). And there was significant difference in the change of graphic rating score of menstrual cramps between both groups(z=-3.637. p=.000). 2) After moxibustion heat therapy. the score of face rating scale of menstrual cramps was decreased significantly from 3.95(SD=0.71) to 2.32(SD=1.00) in experimental group(z=-3.457. p=.000). And there was significant difference in the change of face rating score between both groups(z=-2.713. p=.007). 3) After moxibustion heat therapy. the score of adjective labor pain rating scale rank (ALPRS) of menstrual cramps was decreased significantly from 23.63(SD=4.19) to 17.27(SD=6.34) in experimental group(z=-2.941. p=.001). But there was no significant difference in the change of adjective labor pain rating score(ALPRS) of menstrual cramps between both groups(z=-1.918. p=.059). 4) After moxibustion heat therapy. the score of dysmenorrhea was decreased significantly from 7.0(SD=2.89) to 5.26(SD=3.54) in experimental group(z=-2.183. p=.029). But there was no significant difference in the change of the score of dysmenorrhea between both groups(z =-1.555. p=.125). 5) After moxibustion heat therapy, the score of ADL difficulty was decreased significantly from 33.26(SD=4.58) to 28.83(SD=9.44) in experimental group(z=-3.552. p=.000). And there was significant difference in the change of score of difficulty of ADL between both groups(z=-4.110. p=.000). The above finding indicated that the moxibustion heat therapy showed a practical effect on reducing menstrual cramps, dysmenorrhea and ADL difficulty in female. Accordingly. we can adopt the moxibustion heat therapy as a useful intervention in the community nursing.

  • The traditional Asian medicinal herb, roots of Astragalus (A.) membranaceus (Leguminosae), is used for many purposes, some of which are purported to stimulate the release of growth hormone in vivo. Extracts of A. membranaceus were tested to determine whether they stimulate the release of growth hormone in rat pituitary cell culture. A. membranaceus was extracted sequentially with 80% ethanol (fraction A), n-hexane (fraction B); the test compound from the herbal extraction was isolated using silica gel column chromatography and was identified with spectral data. Test compound was also extracted by traditional boiling water methods. Induction of growth hormone in pituitary cell culture was conducted with isolated compounds and extracted fractions of A. Radix (dried roots of A. membranaceus). The fraction A was not active in the rat pituitary cell culture, but the fraction B derived from the ethanol fraction stimulated the release of growth hormone in culture. Six compounds from fraction B (1-6) were isolated and identified previously. The compounds 1,2-benzendicarboxylic acid diisononylester (1), $\beta$-sitosterol (2), and 3-Ο-$\beta$-D-galactopyranosyl-$\beta$-sitosterol (5) did not induce growth hormone release in the culture. Formononetin (3), 9Z, 12Z-octadecadienoic acid (4), stigmast-4-en-6$\beta$-o1-3-one (6) and 98-E, a mixture of 1'-9, 12-octadecadienoic acid (Z,Z)-2',3'-dihydroxy-propylester (7) and 1'-hexadecanoic acid-2',3'-dihydroxy-propylester (8) stimulated the release of growth hormone in the rat pituitary cell culture significantly compared to the control. In conclusions, four compounds isolated from extracts of A. Radix induced growth hormone release in the rat pituitary cell culture. The 98-E isolate was the most active inducer of growth hormone release.

  • The need for insect and mite resistant turfgrass cultivars arose because of problems associated with pesticide use. Representative cultivars and genotypes of 18 warm-season turfgrass [Zoysia japonica Steud., Z. japonica${\times}$Z. metrella hybrids, Z. japonica${\times}$Z. tenuifotia hybrids, Z. matrella (L.) Merr., Cynodon dactylon (L.) Pers., C. dactylon${\times}$C. transvallensis hybrids, Paspalum notatum Flugge., P. vaginatum Swartz., Stenotaphrum secundatum (Walt.) Kuntze, Eremochloa ophiuroides (Munro.) and Buchloe dactyloides (Nutt.) Engelm.] and 20 cool-season turfgrasses [Poa pratensis L., Festuca arundinacea Schreb., F. rubra L., F. rubra var. commutata Gaud., F. ovina var. duriuscula L. Koch. Agrostis tenuis Sibth., A. palustris Huds., and Latium perenne L.] were evaluated for host resistance to feeding by the Spodoptera depravata (Butler) in the laboratory. Two experiments were set up in the laboratory using 8.5cm diameter${\times}$4.0cm deep plastic petri dishes as larvae feeding chambers. In experiment 1, one neonate larvae were place on the grass in each dish and the dishes were arranged with 5 replicates each within an environmental chamber maintained at $25^{\circ}C$ and 15h light: 9h dark Larval survival and larval weights at 7d and 14d, pupal weights, and days to pupation were compared among turfgrasses. In Experiment 2, 4cm sections of all grasses were oriented equidistant from each other in a pattern resembling the spokes of a wheel. Five one neonate larvae were introduced to the center of each dish. Dishes were immediately placed in an environmental chamber held at $25^{\circ}C$, 15h light: 9h dark Larvae were allowed to feed for 24h. Damage was rated from 0(no damage) to 9(completely consumed) were made for eachturfgrass. Resistance as antibiosis (high mortality, slowed growth, and least preference) was identified in Z. japonica${\times}$Z. tenuifolia hybirids ‘Emerald’, Z. japonica${\times}$Z. metrella hybirds ‘Miyako’ and Eremochloa ophiuroides (Munro.). Cool-season turfgrasses tested were susceptible to feeding by Spodoptera depravata (Butler).

  • 우심실 형성부전이 있으면서 단신방, 그리고 스펀지 좌심실이 있는 매우 드문 질환인 독립된 우심실 형성부전 환아를 경험하였다. 수술 전 우심실의 크기는 좌심실의 반이었으며 삼첨판막의 크기는 z-value로 -4이었다. 수술 시 6세였으며 수술은 양심실성 교정을 시도하여 심방을 2개로 나누어주었으며 3mm 구멍을 남겨 두었다. 수술 후 경과는 좋았으며 외래 추적에서 우심실 기능 부전소견은 없었다. 술 후 27개월에 심도자가 시행되었으며 삼참판막은 잘 자랐으며(z-value=-0.4), 심방중격의 구멍은 저절로 막혔음을 확인하였다. 독립된 우심실 형성부전을 경험하여 성공적으로 양심실성 교정을 시행하였기에 보고하는 바이다.

  • We have developed a planar-type single layer second-order $high-T_{c}$ SQUID gradiometer, which can detect the $d^2$$B_{z/}$dxdy of the second-order field gradient. This SQUID gradiometer consists of four-way 'clover-leaf' pick-up loops and is coupled directly to a 4-junction dc SQUID in such a way that the coupling polarity of the two diagonal loops is opposite to that of the other two loops. The pickup loops are intrinsically balanced for both uniform field and the 1 st-order field gradient. The $YBa_2$$Cu_3$$O_{7}$ thin film was made by pulsed laser deposition method on $SrTiO_3$ single crystal substrate and patterned by photolithography with Ar ion milling technique. Response of this gradiometer was tested for both uniform field and the 2nd-order field gradient. Details of the design, fabrication, and results will be discussed.
