Although the properties of flatness and condition (E) for Sacts over a monoid S are incomparable, Liu([10]) showed that necessary and sufficient condition for a monoid S over which all left S-acts that satisfy condition (E) are flat is the regularity of S. But the problem of describing a monoid over which all cyclic flat left S-acts satisfy condition (E) is still open. Thus the purpose of this paper is to characterize monoids over which all cyclic flat right S-acts satisfy condition (E).

Among the various pulse diagnosis contents in "Hwangjenaegyeong(黃帝內經)", we researched the pulse conditions that are belonged to Sameumsamyang(三陰三陽), and made a comparative study with pulse conditions of five organs[五臟], that of six meridians in "Sanghallon(傷寒論)". So from now on, this study would make help to understand standard pulse condition of Sameumsamyang(三陰三陽) diseases for clinical application. In "Hwangjenaegyeong(黃帝內經)", pulse condition of Taeyang(太陽) is expressed to be floating, Yangmyeong(陽明)'s condition to be strong but with a little bit weakness, Soyang(少陽)'s condition to be intermediate between Eum(陰) and Yang(陽), Taeeum(太陰)'s condition to be low and soft, So-eum(少陰)'s condition to be low and weak with some occasional upward tendency, Gweoleum(厥陰)'s condition to be mixed state of Eum and Yang.

In this paper we study the connection between 2-primal rings, (S,1)-rings and related conditions. And we investigate some condition which is the special case of pseudo symmetric. We also study the condition (KJ) which is given by J. Y. Kim and H. L. Jin. We introduce some condition and we prove that our condition is equivalent to the condition (KJ) when it is an (S,1)-ring.

In this paper, we study the asymptotic behavior of orbits ${S(t)x}$ of an asymptotically nonexpansive semigroup $S = {S(t) : t \in G}$ for a right reversible semitopological semigroup G, defined on a weakly compact convex subset C of Banach spaces with Opial's condition for any $x \in C$.

The purposes of this research were to investigate the general trends and differences of family members' satisfaction and attitudes related to mother's employment condition, to examine the correlations between every members' employment condition, to examine the correlations between every members' interactions, and to analyze the effects of related variables. To study these objectives, three kinds of questionnaire were used and the data were obtained through 780 parents and adolescents. The jmajor findings were as follows: 1) The general trends of family member's interactions showed that the score of relationship satisfaction between mother and adolescent was higher than father and adolescent. Nonemployed mothers and their children were more traditional in attitudes. 2) The correlations of family member's interactions were significant in satisfaction. Husband's occupational attitudes were related with wife's interactions were significant in satisfaction. Husband's occupational attitudes were related with wife's satisfaction, and parentadolescent attitudes were related each other in dual earner family. 3) Mother's marital satisfaction was affected by employment condition, communication satisfaction, husband's aid, support, satisfaction for employment condition, and father's was affected by communication satisfaction and wife's marital satisfaction. Adolescent's satisfaction with father was influenced by satisfaction with mother and mother's employment condition, and sex-role attitudes were influenced by employment condition and father's support.

In this paper, we deal with the asymptotic behavior for the almost-orbits {u(t)} of an asymptotically nonexpansive semigroup S = {S(t) : t $\in$ G} for a right reversible semitopological semigroup G, defined on a suitable subset C of Banach spaces with the Opial's condition, locally uniform Opial condition, or uniform Opial condition.

The graph of the parallelogram law is well known, which gives rise to the characterization of an inner product space among normed linear spaces [6]. In this paper we will sketch graphs of its deformations according to our previous paper [7, Theorem 3.1 and 3.2]; each one of which characterizes an inner product space among normed linear spaces. Consequently, the graphs of some classical characterizations of an inner product space follow easily.

This study was to investigate the human's physiological responses and subjective sensations with wear trial through seasonal condition by age. Climate chamber was set $5^{\circ}C$, RH 45% for winter and $30^{\circ}C$, RH 65% for summer condition. Thirty male subjects were volunteered consisted of 10 people in their 20s, 40s, and 60s. In this study physiological responses such as rectal temperature, skin temperature, clothing microclimate, heart rate and blood pressure were measured. As for age, 60s was the highest in rectal temperature regardless of seasonal condition. In skin temperature, 40s was the highest in winter and 20s was the highest in summer. In clothing microclimate temperature and heart rate, 20s was the highest regardless of seasonal condition. And blood pressure was appeared the highest in 20s regardless of seasonal condition. Subjective sensations such as temperature sensation, wetness sensation and thermal comfort were measured. The subjects revealed that temperature sensation was higher 20s than 60s. Compare of other age group, 60s felt colder in the same environment and clothing. It suggested that temperature susceptibility in 60s became weakened showing no change sensation during the cold exposure. Wetness sensation was higher 20s than 60s. Thermal comfort of 60s was felt more discomfortable than any other age group. This means require the supplement of a suitable clothing in order to adjust to change of environmental conditions.

This study was conducted to investigate the effect of interview techniques on memory accuracy and suggestibility of preschool children. Forty-five preschool children participated in a magic show(target event) and 1 week later, all children received suggestive interview in two conditions(language condition & drawing condition). Another 1 week later, all children's recall contents of the magic show was assessed. During suggestive interview, children in drawing condition show more 'acception' response than children in language condition, and children in the question condition show less 'remember' response than children in drawing condition. In second interview children reported more words, and specially ones in language condition report more suggested words than ones in drawing condition. Finally, children's recalls were more accurate on controled informations of the event than on suggestive.

In this paper we study some properties of the Helton class of an operator. In particular, we show that the Helton class preserves the quasinilpotent property and Dunford's boundedness condition (B). As corollaries, we get that the Helton class of some quadratically hyponormal operators or decomposable subnormal operators satisfies Dunford's boundedness condition (B).
