The objective of this study was to examin some animal and sward factors which determine the daily herbage intake of high yielding dairy cows at different levels of daily herbage allowance. In this paper, the principal data relevent to the changes of sward characteristics after five days of daily strip grazing at three experimental peliods were summarized. The pregrazing herbage mass and extended height increased significantly from 5,047 kg OM/ha and 341 mm in period 1 to 6,877 kg OM/ha and 446 mm in period 3, while there was not a significant difference among herbage allowance treatments(average 6,068 kg OM/ha and 410 mm). The live leaf material in the residual herbage showed a greater reduction than the dead material and leaf sheath in terms of extended height, proportion and density. The decreased rates after grazing were higher when the level of herbage allowance decreased. Live leaves were vertically distributed to 50 cm of sward height before grazing. All live lamina distributed to 25 cm were grazed in the high and medium, and to 20 cm in the low levle of herbage allowance after grazing. The depth of grazing and grazed volume of forage material were heighly affected by the levels of hehage allowance. The biomass after grazing in the high, medium and low daily herbage allowance decreased 35, 36 and 52%, respectively, compared to before grazing level. The highly significant correlations between herbage allowance and extended tiller height(r=0.79), proportion of live lamina(r=0.94) and density of live lamina(r=O.91) after grazing, respectively, were observed.

The purpose of this study is to find a solution to effectively nurse elderly people in the aging society of next generation by analyzing relationship among the social problem of elderly people in the future society, their preferred life style, and their understanding level of an asylum for the aged. Data for this study were collected by questioning 316 persons(257 visitors at C University hospital and 59 residents in Chun - Ra Nam Do) from December 1996 to March 1997. The results were as follows: The assumption that an individual's preferred life style at old age depends on his /her understanding level of the social problem of elderly people was verified ($X^2=9.75$, p<0.00). The assumption that one's understanding of an asylum for the aged depends on his /her understanding level of the social problem of elderly people was verified ($X^2=4.40$, p<0.05). The assumption that one's understanding of an asylum for the aged depends on his/her pre-ferred life style at old age was verified($X^2=34.51$, p<0.01). Among those who want to live together with children when they get old, the following differences in their conception were noted: Elderly people who has lost his /her wife /husband should marry again(p<0.01). Children should take care of their parents(p<0.01). Children should live with their parents(p<0.01), A desirable living style for an elderly people. An undesirable living style for an elderly people. Among those who want to live alone when they get old, the following differences were observed: It is okay for children to live separately from their parents as long as they provide financial support(p<0.01). Any child, regardless of the distinction of sex or the order of birth among siblings, can take care of his/her parents(p<0.05), It is desirable for an elderly people to live alone (p<0.01). It is undesirable for an elderly people to live in an asylum for the aged(p<0.05). It was verified that those who view an asylum for the aged in a negative way believe that children should take care of their parents. Also, it was verified that those who view an asylum for the aged in a positive way believe that children should provide financial support to their parents even though they do not live together(p<0.01). Regardless of the subjects' opinions on seriousness of the social problem of elderly people, the assumption that any child, regardless of the distinction of sex or the order of birth among siblings, can take care of his/her parents was verified(p<0.01) (p<0.05). Regardless of the subjects' view on asylum for the aged, the assumption that it is undesirable place for an elderly people to live was verified (p<0.01). The assumption that one's understanding of an asylum for the aged depends on the distinction of sex among general characteristics such as sex, age, educational background, occupation, and religion was verified(t=-2.82, p<0.01). The assumption that an individual's preferred life style at old age depends on the distinction of sex among general characteristics such as sex, age, educational background, occupation, and religion was verified(t=l.68, p<0.l).

This research challenges the general notion of one-person households of the elderly during widowhood as impoverished, isolated, and vulnerable. Recognizing a high potential vulnerability, however, this research attempts to describe the diverse composition of one-person households of the elderly. For this purpose, relying on 2% sample data from the 2000 census, it examines regional distribution, socio-economic characteristics, and determinants of one-person households of the elderly during widowhood. Socio-economic characteristics of one-person households of the elderly differ by region. Jeju island is distinct in terms of sex and age distribution, and residence area of children. In general, rates of economic activity and self-subsistence are higher in provinces than in cities. Compared to the elderly living with family, the elderly living alone show high rates of economic activity, self-subsistence, and capability of physical activity. Results of logistic regression analysis of determinants of living arrangement are consistent with those of descriptive statistics. Those who are economically active and able to move around without assistance tend to live alone after the death of a spouse. Number of sons and living in an urban area are negatively associated with living alone, whereas females are more likely than males to live alone. According to the separate analysis by age, the positive effect of economic activity is greater in the oldest of the old than in other age groups. Those who possess high educational attainment tend to live alone when they are 80 and older, unlike other age groups. Based on these findings, this paper finds that one-person households of the elderly nay not always be the most vulnerable group, and are diverse in terms of socioeconomic characteristics.

Purpose : The experiments was undertaken to evaluate the effects of herbal medicine, Ojeoksan, in pregnant rats Methods : Female Sprague-Dawley rats were orally administered with the Ojeoksan at dose of 5mg/kg/day for 20 days. Pregnant rats were sacrificed at 20th day of gestation, and observed internal and reproductive organs. Approximately live fetuses in the 20th day of gestation were randomly selected and fixed in 95% ethanol. Results : Maternal body weight of Ojeoksan treated group has a tendency to increase compared to that of control group. There were no significant difference in internal and reproductive organs. There were no significant changes between two groups in blood chemistry and hematological values. There were no significant changes in number of corpus luteum, implantation, live fetuses and sex ratio. But Ojeoksan administered group showed higher delivery rate, early resorption rate than the control group. Also Ojeoksan administered group showed higher implantation rate, late resorption rate than the control group. Conclusion : From these results, it can be concluded that Ojeoksan showed no toxicity effects on maternal body weight and number of live fetuses. There were no significant changes in organ weight, hematological data, reproductive organs. We need more precise study to investigate the mechanism of early or late resoption by the herbal medicines such as Ojeoksan.
