From March 1990 to February 1993, we evaluated completely follow-uped 68 cases of amenorrhea, oligomenorrhea, infertility(anovulation). The ratio of primary to secondary is 31: 37. Ovulation rate and pregnancy rate of 68 cases which were completely treated with clomphene citrate is 72%, 71.8% respectively. Among these 23 pregnat cases, 19 cases were full term delivered, 1 case is ongoing pregnant, and 3 cases were spontaneously aborted. No one of multiple pregnancy and congenital abnormality was noted.
단열 및 가열보온 양생을 조합한 한중 콘크리트의 초기보온 양생 및 배합계획

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.
