The purpose of this study is to investigate the Korean's value of children and perception of parenting difficulty through the agreement to the three kinds of Korean proverbs: difficulty of parenting, preference of son and value of daughter. Also, this study attempted to identify whether the value of children and the perceived difficulty of parenting measured by the agreement of the proverb is related to the number of children they thought as ideal before marriage and the number of children they actually have. Total 385 married men and women who have a job participated in the survey. Main result is as follows. 1) In most cases, the ideal number of children was at least equal or more than the actual number of children. 2) The subjects showed higher degree of agreement to the proverbs regarding the difficulty of parenting than the preference of son or the value of daughter. 3) The degree of agreement to each kind of proverbs were different in terms of some demographic variables such as age and sex. 4) When the age effect controlled, the ideal number of son had correlation with the agreement to the son-preference proverbs while the ideal number of daughter or total children had no correlation with agreement to any kinds of proverb. The actual number of son was positively correlated with agreement to the son-preference proverbs while actual number of daughter was negatively correlated with it. In conclusion, this study suggests the Korean's value of children has been rapidly changing and it has, in part, an effect on the number of children they want to have or they actually have.

The purpose of this study is to investigate the experience of abortion and practice of contraception in view of preventive in order to analysis the degree of family planning according to the sex & number of actual children. We collected data on married conceptive women who are resident in Seoul and from 20 age to 49 age. This was carried out from 26 July, 1993 to 25 August, 1993. This collected data was analyzed through x² Logistic regression using SAS/PC/sup +/and SPSS/PC/sup +/. The analyzed results are as follow. 1. Those who answered "son is not positively necessary"are only 15.7% among investigated women. 2. The percentage of practicing contraception was 68.2%, in case of 30s' women it was 74.3% and most high. Also, in view of religion, the percentage of practicing contraception of Buddihist was most low as 61.54% (p<0.05). 3. The portion of those who had sons more than four who used permanent. method of contraception is most high(83.3%), in terms of composition, while the ratio of those who have only son is 60.7%, the ratio of those who have only daughter was only 14.3%. 4. In order to investigate the independent variable affecting practice of contraception, we analysed data with Logistic regression analysis. The result of this analysis is as follows: the older(p<0.01) woman is and the higher the level of education of woman(p<0.05), the more it affects significantly practice of contraception. 5. In abrotion experience, the number of experienced women was 241(50.3%) and including repeated abortion, the total number of abortion is 317. The main reason of abortion was that they didn't want more child. The number of abortion due to such reason was 153(48.3%), Especially, the 181(43.0%) cases among last pregnancy 421 cases were the undesired pregnancy. So, the 147 cases of them came to abortion. 6. In the number of actual children, the ratio of those who have three children occupied high portion(56.7%, p<0.05), for the composition of children, although the case of those who have both son and daughter showed most high ratio of experience of abortion, but it was statistically insignificant. 7. In order to investigate independent variable affecting experience of abortion, we used Logistic regression analysis. The result of the analysis was that the older women was(p<0.01) and the more they had actual children(p<0.01), it significantly affected abortion.

The purpose of this paper is to know the effects on number and operation abilities of the 1st grade children of elementary school by applying teaching and learning activity throught communication. For this purpose, we have studied according to the following procedure. 1. We divised teaching and learning model through communication and applied in the actual teaching and learning activity. 2. We investigated the effects of number and operations abilities of the 1st grade children by applying teaching and learning activity through communication. To accomplish this purpose, we applied learning activity through communication to the 1st grade of 40 elementary school children for about six months(September 1, 1999 ～ February 20, 2000). In process of applying this model, we collected all sorts of cases in the children's learning activity and investigated children's response on learning activity through communication, interview with children and researcher's observation. We applied the model through communication in class and compared with the traditional learning. 1. In learning through communication, children could solve the problem in themselves with a sense of responsibility. 2. It was impossible to find out the degree of children's comprehension in the explanatory learning. But in the learning through communication, it was a great help to individualize and plan the learning because children express their ideas clearly. It has conclusion as follows. The learning activity through communication has effected on forming number and operations abilities of the 1st grade of elementary school children importantly. 1. Children have improved in the abilities through communication to express their own ideas. 2. Children have studied with a sense of responsibility not in the teacher-oriented learning but in the self-directed learning 3. Children could find out the mathematical concepts in themselves - correcting false concepts, reguiding concepts by errors, finding invisible errors, solving problems variously and knowing the easy method. 4. The activity through communication in mathematics was a base of children's individual learning and important data of next learning plan. 5. The mathematical concepts formed through communication had a high transfer of learning. 6. Children have taken pleasure of discovery and had affirmative attitude about mathematics learning. We can make sure that number and operations abilities of the 1st grade children are formed by applying teaching and learning activity through communication. However, help and control of teacher have to be with it.

This study is intended to check economic value of and factors influencing children's library. To this end, data on a total of 614 questionnaires to which parents among users of 6 children's libraries responded were collected. The results of analysis by contingent valuation method after selecting library fee per person as payment vehicle were as follows. First, willingness to pay was estimated to be a monthly average of KRW 9,243 per person. Second, it was shown that factors influencing willingness to pay included the frequency of utilization, satisfaction, the number of children per family, gender, age, and income and so on. Third, with regard to influence according to each factor, an additional unit in all the rest of factors except gender increased probability of willingness to pay such as the frequency of utilization(1.140), satisfaction(1.335), the number of children per family(1.417), age(1.124), income(2.426). On the other hand, in terms of gender, probability of willingness to pay was lower in female by 0.364 than in male. The implication of this study is that an interview is held with actual user and specific amount of money is presented regarding the economic value of children's library, which has been little known until now.

In this paper, exact confidence interval of hyper-geometric parameter, that is the probability of success p in the population is discussed. Usually, binomial distribution is a well known discrete distribution with abundant usage. Hypergeometric distribution frequently replaces a binomial distribution when it is desirable to make allowance for the finiteness of the population size. For example, an application of the hypergeometric distribution arises in describing a probability model for the number of children attacked by an infectious disease, when a fixed number of them are exposed to it. Exact confidence interval estimation of hypergeometric parameter is reviewed. We consider the performance of exact confidence interval estimates of hypergeometric parameter in terms of actual coverage probability by small sample Monte Carlo simulation.
