This study was carried out to determine the effect of sowing time on the flowering, growth and yield of Scutellaria baicalensis Georg, which was collected from Yeochon district, cultivated after barley in the southern coastal areas of Korea. Emergence and flowering dates in the sowing time of June 1 were earlier than those of the other sowing times. In the sowing time of June 1, length and diameter of main stem, number of node per main stem, number of branch per plant and dry weight of stem leaves were greater than those of sowing times of June 10 and June 20. Yield components such as main stem length and diameter, main stem numbers, branches per plant, dry weight of stem leaves, main root length and thickness, number of large root and fine root per plant, and dry weight of root were the highest at the sowing time of June I as the yield of 71.3kg/10a. Optimum sowing time of Scutellaria baicalensis Georg cultivated after barley was June 1 in southern areas of korea.

This study was carried out to get infirmation for the breeding varieties and developing the cultural methods with representative 32 cultivars which were diffused from 1900 to 1982 and two cultural methods which were old one i.e., low dressing and late planting and modern one i.e., medium dressing and early planting. Duration of transplanting between cultural practices were 15 days but the duration of heading date were 5days. Panicle projecting duration was 5-10 days in all cultivars, especially, it is 5 days in early maturing varieties, 6-7 days in medium maturing varieties and 7-10 days in late maturing varieties. Periods from transplanting date to effective ripening date were 99.8 days in low dressing and late planting method, 106.2 days in modern one but the periods from heading date to effective ripening date were 31.4 days in low dressing and late planting method, 30.2 days in modern one. Ripening speed was very active from 5 to 10 days after heading and the daily increase of 1000 grain weight was from 847.8mg to 1130mg in that time and it slightly increased from 5 to 35 days after heading in Japonica varieties but increased after heading and suddenly decreased at 30 days after heading in Indica/Japonica varieties. Meteorological factors (temperature and amount of solar radiation) were positively correlated with the ripening speed but negatively correlated with the period of physiological and effentive ripening.

The effects of cook-chill and sous-vide upon the vitamin retention and acceptance of soybean sprout muchim and soybean sprouts soup were evaluated. When the sous-vide packaged soybean sprout muchim was stored at 3$^{\circ}C$ for 1, 3, and 5 days, the contents of thiamin, riboflavin, and ascorbic acid were not changed. However, the nutrient contents were changed in sous-vide packaged soybean sprouts soup stored at the same conditions at each storage time up to 5 days. The contents of thiamin, riboflavin, and ascorbic acid showed the lowest level at 5 days after storage. Regarding customer's acceptance of sous-vide packaged soybean sprout muchim compared to the freshly cooked one, the former had a higher score in taste and color than the latter. Overall acceptability of the sous-vide soybean sprout muchim had a lower score than that of the freshly cooked one, but the sensory characteristics did not show any significant difference between them. The freshly cooked soybean sprout soup had higher scores in taste, flavor, color, texture, appearance, and overall acceptability than the son-vide packaged soybean sprout soup. The former, however, had a significantly higher score in color (p＜0.05) and the overall acceptability (p＜0.01) than the latter.

We examine how women entrepreneurs in contents business experience work/family role conflict and then reveal what kind of conflict management strategies they adopt in varying external and internal conditions. A critical problem faced by female entrepreneur is the tension that exists between their personal lives and business role. This tension is viewed as a form of inter-role conflict in which the role pressure from work and family competes for women's limited time and energy. First, we probe the content and nature of work- family role conflict on the part of female entrepreneurs. Second, we closely look at the three strategies of work/family role manipulation. Family role reduction strategy, work role reduction strategy, and work/family role sharing strategy are identified. Third, we discuss how the choice of the three strategies is affected by internal family salience and the external resources including spouse, family, and financial resources.

This study was carried out to determine the optimum planting time for in vitromultiplied tuber of Pinellia ternata(Thunb.) Breit. The tubers were planted on April 20, May 20, June 20, July 20, August 20 and September 20 in 1990. Emergence ratios were 68 to 87% in any planting time except planting on July 20. The number of tubers per $m^2$ at harvest in plantings on May 20 and June 20 were significantly higher with 1,110 and 1,021, respectively, while in plantings after July 20, those were drastically decreased. As compared with fresh yield of planting on April 20(352kg /10a), that of May 20 was 109% and June 20 was 103%, while those of after July 20 were from 41% to 19%. There was a highly positive correlation between dry tuber yield and the number of tubers per $m^2(r=0.991^{**})$. Tuber yields for commercial use(diameter over 7.1mm) were high in planting on May 20(322kg /10a) and on June 20(299kg /10a). It was suggested that optimum field planting time for in vitro multiplied tuber of Pinellia ternata(Thunb.) Breit was from May 20 to June May 20.

The present studies were carried out to examine the effects of exogenous oxytocin(OT) on plasma, uterine and placenta of estradiol-17$\beta$, progesterone, prostaglandin F$_2$$_{\alpha}$ (PGF$_2$$_{\alpha}$), Prostaglandin E$_2$(PGE$_2$) and OT receptor concentrations in pregnant rats. Pregnant rats received an injection of exogenous OT on days 14, 16, 18, 20, 22 of pregnancy and day 1 of postpartum. Concentrations of plasma estradiol-17 $\beta$ after OT injection started to increase after day 18 and peaked on day 22 of pregnancy but decreased on day 1 of postpartum. Plasma progesterone concentrations declined gradually from day 18 of pregnancy and decreased more rapidly until postpartum 1 day. Concentrations of estradiol-17$\beta$in uterine tissues after OT injection were sharply increased from day 20 to 22 of pregnancy and progestrone concentrations were peaked on day 16 and decreased rapidly from day 16 to 20 and maintained the same level until day 1 of postpartum. Uterine concentrations of PGF$_2$$_{\alpha}$ and PGE$_2$increased gradually until day 20 and peaked on day 22 of pregnancy but showed a marked decrease on day 1 of postpartum. Concentrations of PGF$_2$$_{\alpha}$ in placental tissues increased rapidly from day 14 of pregnancy and decreased sharply on day 1 of postpartum. Concentrations of PGE$_2$increased gradually after day 14 and peaked on day 20 of pregnancy. The concentration of OT receptor in uterus was significantly elevated from day 20 and rose to maximum on day 22 of pregnancy. These findings show that OT suppress the concentration of progestrone and stimulate productions of estradiol-17 $\beta$, PGF$_2$$_{\alpha}$, PGE$_2$ and oxytocin receptor concentrations in pregnant rats.

연두금파리의 유충-번데기-성충의 발생에 따른 cyclic AMP(CAMP)와 ecdysteroids의 농도 및 cyclic AMP-dependent protein kinase(PKA)의 활성도를 High Performance Liquid Chromatography(HPLC)와 Liquid Scintillation Counter(LSC)를 이용하여 측정하고 상관 기능 변화를 조사하였다. CAMP의 농도와 PKA의 활성도는 종령유충 및 성충에서 낮은 갓(0.29 UM/g, 5.52~5.59 unit/mg)을 나타내었고 번데기 0일(0.49 UM/g. 92.22 unit/mg)과 7일(0.50UM/g, 24.45 unit/mg)에서 최고치를 보였으며 번데기 4일에서 최저수준(0.13 $\mu$M/g3.23 unit/mg)을 나타내었다. Ecdysone 농도는 번데기 2일에 최고치(37 84 USlg)를 4일에 최저치(18.46 Ugyg)를 보인 후, 5일에 24.37 1519로 상승하였으며 성충에서는 낮은 값을 나타내었다 그러나 20-hydroxvecdysone 농도는 번데기 4일(23.66 UgyS)과 번데기 6일(14.90 Ugyg)에 최고치를 이루었고, 7일에서 최저치(1.21 USi9)를 나타내었다.

본 연구는 미취학 자녀를 둔 취업중인 치과위생사의 일-가정 갈등, 일-가정 균형의 관계를 조사하였다. 일-가정 갈등 평균 2.63, 낮은 나이, 양육자 조부모, 높은 양육비, 높은 배우자만족도, 낮은 가구소득, 낮은 경력이 높았다. 일-가정 균형 평균 3.63, 낮은 양육비, 높은 배우자만족도가 높았다. 일-가정 균형과 일-가정 갈등은 음의 상관관계로 일-가정의 균형을 높여 경력단절을 줄이기 위해서는 사회적, 국가적 대책마련이 필요하리라 사료된다.
