In this paper, strength correction and heat curing method of the concrete subjected to cold weather was studied based on Korean Architectural Standard Specification(KASS) and Japanese Architectural standard specification(JASS). KASS stipulates that a strength correction based on water to cement ratio correction is to be considered to compensate strength retardation due to low temperature. Hence, the concrete with 24 ㎫ of design strength supposed to be applied is modified to 27 ㎫ based on KASS. For preparing heat curing method, combination of heat supplying and heat insulation method with double layer bubble sheet was selected to gain economical profit. According to JASS, the application of the method mentioned above makes the heat loss reduced by as much as 35% and thereby, more than 30% of heat supply apparatus was reduced. Field test indicated that the concrete with 27 ㎫ exceeded target design strength of 24 ㎫ at 28days, which is shorter than designed control age 42 days.

To evaluate the effectiveness of GnRH agonist for the treatment of uterine myoma as a cause of infertility, fourteen women were recruited to the study. The patients were treated with a delayed-release formulation of D-$Trp^6$-LHRH in biodegradable microcapsules(Decapeptyl-CR), administered intramuscularly at four week intervals for a period of six monthes. The first injection was given on day 21 of the cycle. Serum estradiol levels fell significantly to the mean value of 257.7pgjml 4 weeks after the first injection. Eleven patients in fourteen treated patients had a reduction in the size of uterine myoma as assessed by ultrasonography, two patients had no change of size and one patient had a increase of size. After the first or second injection, all patients became amenorrheic, then resumption of menstruation ocurred at 12 to 14 weeks after the last injection. Common side effects were hot flush, sweating and dyspareunia, whitch were acceptale. In Eleven patients who had a reduction in the size of uterine myoma by treatment with a delayed- release formulation of D-$Trp^6$-LHRH(Decapeptyl-CR), after above treatment with GnRH agonist, then four patients were treated with myomectomy, three patients had pregnancy and full term delivered by Cesarean section. These data suggest that administration of a delayed-release formulation of a GnRH agonist can be a worthwhile and convenient approach to the medical treatment of uterine myoma as a cause of infertility.

본 연구는 환경친화적 단백질 HrpNEp를 처리하여 백합의 생육특성을 알아보기 위해 수행하였다. 환경친화적 단백질 HrpNEp 백합의 줄기 길이 신장을 촉진하고 두께를 굵게 하며, 줄기의 경도를 높여주고 절화의 휘는 정도를 감소시켰다. 또한 줄기내 무기질 함량 중 줄기 경도 향상에 유리한 칼슘과 마그네슘의 흡수를 촉진하였다. 환경친화적 단백질 HrpNEp 처리는 10mg L⁻¹의 농도에서는 4회 이상 그리고 40mg L⁻¹에서는 2회의 처리만으로도 각각의 품질 요인면에서 효과가 상승하는 것으로 조사되었으며, 처리 횟수를 많이 할수록 효과는 우수하였다. HrpNEp와 칼슘 또는 마그네슘과의 교호처리는 백합줄기 내 흡수에 상호 길항작용이 관찰되었으며, 환경친화적 단백질 HrpNEp는 길항작용을 일으키지 않는 한도 내에서 마그네슘과 특히 환경친화적 단백질 HrpNEp 10mgㆍL⁻¹과 칼슘의 교호처리와 HrpNEp 40mg L⁻¹ 단독처리가 백합 절화의 품질에 유리하였다. This study was conducted to investigate the effect of HrpNEp protein extracted and purified from Erwinia pyrifoliae WT3 on the growth and cut flower quality of oriental hybrid lily. HrpNEp, a kind of environment-friendly protein, stimulated growth of the shoot length and stem diameter, and increased the stem strength, but decreased the curvature of the shoots with flower buds. Calcium and magnesium which are supposed to have some positive effects on the hardness of tissues were absorbed more in HrpNEp-treated shoots than the control. To improve the quality of cut flowers, the lily needed 4 or 2 times treatments with 10 or 40 mg L⁻¹ HrpNEp, respectively, and additional treatment with HrpNEp gave even better quality. There was some antagonism between magnesium and calcium when they were used alternatively with HrpNEp. High quality cut flowers were produced by treatment with 10 mg L⁻¹1 HrpNEp and calcium, with a synergistic effect within the limits of antagonism, and also with 40 mg L⁻¹ HrpNEp treatment alone.
