We investigated the quality of soybean paste(Doenjang) fermented by BAcillus brevis. The results obtained were as follows : soybean paste fermented by Bacillus brevis had alkaline pH and yellow ochre color. Dextrinizing activity was about 98 D.P. unit from 5th to 25th day of fermentation at 3$0^{\circ}C$ and after that day somewhat decreased . Saccharifying activity was respectively 6.1, 7.2, 6.8, 6.4 S.P. unit on 5, 15, 25 and 35th day of fermentation. Protease activity suddenly increased after 15th day of fermentation and was 250, 275, 299 unit on15, 25, 35 th day of fermentation , respectively. The most abundant free amino acid was found to be glutamic acid (561.8mg%) in soybean paste fermented by Bacillus brevis. In case of free sugar and non-volatile organic acid, fructose and oxalic acid showed highest content of 10.25mg% on 25th day and 12.20mg% on 15th day. The contents of free amino acids, free sugars, organic acids in soybean paste fermented by B.brevis were most abundant after 25 days of fermentation and this results were similar to that of traditional soybean paste. The odor of soybean paste fermented by Bacillus brevis was improved to be a nice soybean paste odor on 25th day of fermentation. However, sensory evaluation value of the taste of it decreased after 10 th day of fermentation.

This study was conducted to investigate the contemporary dietary life of residence in Kyunggi province. People living in Kimpo, Yoju districts(farm villages), Kapyung districts (mountain villages) and Hwasung districts (fishing villages) were selected for this research as subjects from August S to 19,1997. The results of the survey are summarized as follows: 1. Cooked rice was a staple food. However nuddles and soojaebees(soup with dough flakes) was taken as lunch or snacks but Juk(rice guel) or Dduk(rice cake) was not treated as a meal. 2. Dishes were consisted with soup or chigae, kimchi and namul(seasoned vegetables), and fishes, meats, salted sea foods, dried fishes, jangacchi(dried seasoning radish) were also taken by sometimes. 3. Soy sauce, bean paste, red pepper bean paste were made by every home even if they were very busy. 4. Festival days such as New Year's Day, daeborum(the 15th day of January), chusok(mid-autumn festival), and kosaa(October ceremony) and dongee(one of 24 seasons by lunar calendar) are skipped oftenly and slowly forgotten by people. They do not celebrate Samgin-nal(the third day of March), Buddha's birthday(the 8th day of April by lunar calendar), danoh(the 5th day of May), yoodoo(the 15th day of June), chilsok(the 7th day of July), Jungyang(the 9th day of September) and the last day of the year either 5. Due to improved kitchen system, we couldn't see the old kitchen devices.

Serial ultrasonographic examinations were daily performed on 8 bitches (5 Maltese and 3 Yorkshire terrier) from day 15 until parturition to determine the size of gestational structures. Gestational age was timed from the day of ovulation (day 0), which was estimated to occur when plasma progesterone concentration was first increased above 4.0 ng/ml. When the size of fetal and extra-fetal structures according to gestational age was measured, there was a difference between Maltese and Yorkshire terrier in extra-fetal structures (P<0.001), and no difference in fetal structrures (P<0.001). The correlations between the gestational age and the growth in fetal and extra-fetal structures were examined by regression analysis. The extra-fetal structure which showed high correlation from day 20 to 35 was inner chorionic cavity diameter in two breeds. The fetal structures which showed high correlation from day 36 until parturition was fetal head diameter in two breeds. In conclusions inner chorionic cavity diameter was the most accurate for estimation of gestational age and prediction of whelping day from day 20 to 35, and fetal head diameter from day 36 to parturitions respectively. Ultrasonography is very useful tool to evaluate the gestational age and to predict the whelping day in pet dogs.

The aim of this study was to estimate of ovulation time and parturition day at the same time as breeding in small dog by vaginal cytology and to confirm the accuracy by comparing the expected parturition day and the real one. Characteristic features of vaginal cytology during the estrous cycle were the high proportion of large intermediate cell, superficial cell, anuclear cell and erythrocyte in proestrus, superficial cell and anuclear cell in estrus, parabasal cell, small intermediate cell, large intermediate cell and leukocyte in diestrus, parabasal cell and small intermediate in anestrus, respectively. When day 0 was the parturition day, the period of pregnancy is 67.45(64~75) days when the cornification index (CI) is over 90%. Also, on the basis of ovulation day, 63.65(59~66) days was confirmed, and 57.0(52~60) days was confirmed based on the first day of diestrus. There are the gap of 4 days between the day being over 90% in CI and ovulation day. On the basis of this, when expecting parturition day based on the day being over 90% in CI by vaginal cytology, 18.1% was produced in the same of the expected parturition day and the real one, 30.3% and 33.3% were produced in the gap of one day and two days, respectively so, the accuracy within two days was 81.7%. In addition, based on the first day of diestrus, it also was identified to 81.7% as the difference between the expected parturition day and the real one within 2 days. It demonstrated there are any difference between any expected parturition day by vaginal cytology. Thus on the basis of the day of being over 90% CI, it is fully thought to using clinically due to the possibility of prediction the parturition day at the same time as the determination of the proper time of the optimal mating time.

The purpose of this study is to get the data on the day-care type of the employed mothers in urban area and to make it improve the day care service program. I classified day care type into four classes accoding to existing one. And we surveyed 401 employed mothers with the child under age of six who lived at Seoul. the major results were as follows; 1) Most of employed mothers felt the burden of day care expenses and payed it of their own earning 2) The common type of day care is 'by family' and the users of this type more satisfied with the condition than any other types. 3) the difficulty of day care is that can't apply the tool and materials sufficiently, except day care center, 4) The reason that they use day care center or not is thier family. 5) Accoding to child age, family composition, educational level, job, income level, employed mothers choose day care type differently. So I suggest the social support for the employed mothers.

During prolonged exposure to the sun for 8 h each day for 10 days in which the highest ambient temperature around 14:00 h was $39^{\circ}C$, buffaloes exposed to the sun without shade increased the turnover of body water by 35% and 76% on day 5 and day 10 of exposure respectively. The total body water markedly decreased on day five and this amount was maintained thereafter. Plasma and blood volumes did not change significantly on day five but markedly decreased on day 10. Packed cell volume significantly decreased on day five and day 10 of the exposure period. The reduction of packed cell volume on day 10 coincided with the decrease in total plasma water. On day 10 of the exposure, an increase in the rate of liquid flow from the rumen was noted. It is concluded that on the fifth day of exposure, the increase in the evaporative cooling process was attributed to initial mobilization of water from the intracellular compartment. The reduction of both plasma and cell volumes occurring from day five to day 10 indicated a loss of body water from both intracellular and extracellular compartments.

Serial ultrasonographic examination was daily performed on 12 pregnant Shih-tzu bitches from day 15 until parturition to determine the size of gestational structures. Gestational age was timed from the day of ovulation (day 0), which was estimated to occur when plasma progesterone concentration was first increased above 4.0 ng/ml. Extra-fetal structures were measurable from days 17 to 46. Outer uterine diameter increased from $9.9{\pm}0.4$ mm (Mean${\pm}$SD) at day 20 to $44.3{\pm}0.8$ mm at day 46 and inner chorionic cavity diameter increased from $7.2{\pm}0.2$ mm at day 17 to $36.9{\pm}1.5$mm at day 41. Length of chorionic cavity or zonary placenta increased from $6.6{\pm}0.4$ mm at day 21 to $46.4{\pm}0.9$ mm at day 44. Of the extra-fetal structures, inner chorionic cavity diameter was the most accurate for estimation of gestational age until day 38. Fetal structures were measurable from days 23 to 60. Crown-rump length increased from $3.9{\pm}0.3$ mm at day 23 to $55.2{\pm}3.3$ mm at day 41, fetal body diameter increased from $7.9{\pm}0.6$ mm at day 32 to $47.8{\pm}2$ mm at day 60, and fetal head diameter increased from $6.3{\pm}1.1$ mm at day 29 to $25.6{\pm}0.2$ mm at day 60. Of the fetal structures, fetal head diameter was the most accurate for estimation of gestational age from day 38 until day 60.

The effect of Human Menopausal Gonadotropin(hMG) on the implantation, pregnancy, and the concentration of plasma progesterone were studied in pregnant rats. HMG 75 or 150 IU were administered once on day 1, 2, 3, 4, 9, 12 or 14 of gestation, respectively. Rats were autopsied on day 7 or 18. A single dose of hMG prevented implantation and terminated pregnancy in all of the rats by injecting on either day 1 or day 2 and this abortifacient action was effective 82-98% of pregnant rats on day 3 or 4 and 14-20% on day 9 or 12. Administration of hMG had no effect on termination of pregnancy on day 14. Plasma progesterone concentration by injecting hMG on day 1, 2, 3 or 4 were very decreased.
