We Consider the fuzzification of sub-implicative ideals in BCI-algebras, and investigate some related properties. We give conditions for a fuzzy ideal to be a fuzzy sub-implicative ideal. we show that (1) every fuzzy sub-implicative ideal is a fuzzy ideal, but the converse is not true, (2) every fuzzy sub-implicative ideal is a fuzzy positive implicative ideal, but the converse is not true, and (3) every fuzzy p-ideal is a fuzzy sub-implicative ideal, but the converse is not true. Using a family of sub-implicative ideals of a BCI-algebra, we establish a fuzzy sub-implicative ideal, and using a level set of a fuzzy set in a BCI-algebra, we give a characterization of a fuzzy sub-implicative ideal.

The fuzzification of an ideal in a Lie algebra is considered. Using a level subset of a fuzzy subset of a Lie algebra, we give a characterization of a fuzzy ideal, and using a family of ideals of a Lie algebra, we establish a fuzzy ideal. With relation to the ascending chain of ideals, a characterization for the set of values of any fuzzy ideal to be a well-ordered subset of the closed unit interval [0,1] is stated.

During the period of 1950s and 1960s extreme changes in political, economic, social and cultural environments had a great influence on family ethics, since the western civilization had been introduced to this nation in late 19th century. This paper studied the family ethics during the above periods by interviewing elders(average age 77) who had couple relations at that time focusing the followings. During the period, ① what is the view of family? ② what are the actual sapects and characteristics of married couple ethics? ③ what are the actual aspects and characteristics of the ethics between parents and their children? The results of this study are as follows; ① The indispensable requisite of the parents is a son who functions as the tool for enhancing social position of their family rather than succession of them. The nuclear family is regraded ideal, but the concept of nuclear family of them is far different from that of western. ② The married couples accepts the given couple relations in the name of bringing up their children. The ideal image of wife is traditional wifely virtues and that of husband is ability of making money. ③ The parents emphasize education and success of their children for enhancing the social position of their family, while they still require some degree of moral standards to their children. The parents believe that the best filial piety is making good lives of their children's own, which is somewhat different from the traditional filial piety norm.

Let R be an integral domain with identity. In this paper we will show that if R is integrally closed or if t-dim $R{\leq}1$, then R[{$X_{\alpha}$}] satisfies the principal ideal theorem for each family {$X_{\alpha}$} of algebraically independent indeterminates if and only if R is an S-domain and it satisfies the principal ideal theorem.

We give the characterization of an intuitionistic fuzzy ideal[resp. intuitionistic fuzzy left ideal, an intuitionistic fuzzy right ideal and an intuitionistic fuzzy bi-ideal] generated by an intuitionistic fuzzy set in a semigroup without any condition. And we prove that every intuitionistic fuzzy ideal of a semigroup S is the union of a family of intuitionistic fuzzy principle ideals of S. Finally, we investigate the intuitionistic fuzzy ideal generated by an intuitionistic fuzzy set in $S^1$.

Natural increase rate in population is reached to 1.7% in 1975 fron 2.5% in 1966 because of the effect of Govermental Family Planning Program. The average number of present children and ideal children is just the same, 2.4 people, in this investigation. So, I assume that the number of present and ideal children is approaching each other. The rate of unmarried female workers who don't know even one thing about the know ledge of contraception was 23.9%, and especially that of rural women was 31.5% and 41.3% of them has never experienced contraception. 'Boy-preference' presented 60.1% of unmarried female workers and 79.1% of married women. 'Connection of a family line' related to 'Transfer to next generation of a family line' presented 38.0% and 'Trustworthiness' related to 'Leadership of a family' presented 26.0% (total 64.0%). As this point, Ive can find that this rate reveals the traditional sense of patriarchal system in society and family. The rate of women of experienced artificial abortion has been 52.1% and that of women using it as birth control caused by 'Many children' and 'Short brith-interval' 46.6% of women of experienced pregnancy. So, we can see that artificial abortion is a main cause of Maternal Health destruction.

And we prove that every intuitionistic fuzzy ideal of a semigroup S is the union of a family of intuitionistic fuzzy principle ideals of 5. Finally, we investigate the intuitionistic fuzzy ideal generated by an intuitionistic fuzzy set in $S^{1}$

As a continuation of [4], characterizations of fuzzy implicative ideals are given. An extension property for fuzzy implicative ideals is established. We prove that the family of fuzzy implicative ideals is a completely distributive lattice. Using level subsets of a BCk-algebra X with respect to a fuzzy set $\={A}$ in X, we construct a fuzzy implicative ideal of X containing $\={A}$.

Sam Shepard is one of the leading American playwrights who represented Off-Off Broadway in the l960s and 1970s. In his early days, he wrote many experimental plays but later he turned to realism. However, under the superficial realism in his later plays, we find that they contain experimental devices and themes. True West (1980) is the last play of ills realistic family trilogy. This play shows that the tradition of Old West, which is symbolized and replaced by desert, disappeared in the industrialized clues of modern West. The Old West is compared which the modern West through the struggle of two brothers, Lee and Austin. Their father, 'Old Man', ran out on his family and went to the desert but did not succeed there. He shows that he failed in achieving the American Dream. The family appears unusual and demolished The relationships of the characters are not based on love and belief. The family symbolizes the negative aspects of modern American society. After Austin recognizes the actual situation finding that there is no real life in the modern West, he tries to leave the city and his family. He wants to go to the desert in search of a new life. However, in the last tableau Lee blocks the exit and the two brothers square off. It implies that they are doomed to continue their struggle. The message Implies that American society today is lacking the same positive values they once had in the Old West.

This study develops an the ideal portrait of a human being pursuing in home economics education from a critical science perspective. The practical problem is 'what should the ideal portrait of a human being pursuing in home economics education with a critical science perspective be?' was addressed through a practical reasoning research method with the stages of valued ends, context, alternatives, consequence, and a final plan. The sequential flow of understanding values and contexts established the setting of three valued ends by organizing issues and categorized areas of individuals, families, society, and cultural from a critical science perspective. The ideal portrait of human being was specifically stated, in the self-formation, independent, inter-subjectivity, social participation, and enculturation according to subcategories; in addition, the stated ideal portrait of human being was modified through expert consultations. Alternatives and consequences were reexamined for the validity of the statement and restated as a comprehensive statement of ideal portrait of a human being that included a restatement of the five areas. An ideal portrait of a human being pursuing in home economics education from a critical science perspective was made from alternative ideal portraits of the proposed human being and stated as 'a person who can continually act autonomously in one's life-world.'
