Recently, Cesarean Section has been revealed as major events in maternity nursing, because it has influence on tile formatter of the self concept of cesarean section mothers as well as later coping mechanism and mother-child relationship including the mothering role. The study is conducted to clarify the relationships between the perceired family support and the self concept of cesarean section mothers, and to find out other Influencing factors on the formation of the self concept. Measuring instrument used in this study was Lee's scale to measure the self concept and the degree of perceived family support of the cesarean section mothers, The subject were 155 cesarean section mothers who were selected conveniently. Volunteers answered self reporting questionnaires which asked about their self concept. Data was analyzed as follows using SAS. The relationship between scores of the self concept and degree of the perceived family support was analyzed by Pearson's product moment correlation. In order to identify the influencing effects of demographic variables on the formation of self concept & F test were used. Result were summarized as follows : 1. Scores of self concept of cesarean section mothers were significantly correlated with scores of the perceived family support (r=0.3438, p<0.01) These results show that the family support is closely related to the self concept of cesarean mothers and has positive effects on their coping capacity. 2. Scores of self-concept of those who have lower ducation background and are multipara were significantly higher than those who have higher education background and are primipara(M=29.90$\pm$9.37, 27.69$\pm$3.89, t=2.006, df=105.8, p=0.0480: M=27.75$\pm$3.49. 29.46$\pm$8.68, t=-1.7183, 2. p=0.08).

Let x : $M^{n}$ .rarw. $E^{m}$ be an isometric immersion of a manifold $M^{n}$ into the Euclidean space $E^{m}$ and .DELTA. the Laplacian of $M^{n}$ defined by -div.omicron.grad. The family of such immersions satisfying the condition .DELTA.x = .lambda.x, .lambda..mem.R, is characterized by a well known result ot Takahashi (8]): they are either minimal in $E^{m}$ or minimal in some Euclidean hypersphere. As a generalization of Takahashi's result, many authors ([3,6,7]) studied the hypersurfaces $M^{n}$ in $E^{n+1}$ satisfying .DELTA.x = Ax + b, where A is a square matrix and b is a vector in $E^{n+1}$, and they proved independently that such hypersurfaces are either minimal in $E^{n+1}$ or hyperspheres or spherical cylinders. Since .DELTA.x = -nH, the submanifolds mentioned above satisfy .DELTA.H = .lambda.H or .DELTA.H = AH, where H is the mean curvature vector field of M. And the family of hypersurfaces satisfying .DELTA.H = .lambda.H was explored for some cases in [4]. In this paper, we classify space curves x : R .rarw. $E^{3}$ satisfying .DELTA.x = Ax + b or .DELTA.H = AH, and find conditions for such curves to be equivalent.alent.alent.

For a finite poset $P=(X,{\preceq})$ the fractional weak discrepancy of P, denoted $wd_F(P)$, is the minimum value t for which there is a function $f:X{\rightarrow}{\mathbb{R}}$ satisfying (1) $f(x)+1{\leq}f(y)$ whenever $x{\prec}y$ and (2) ${\mid}f(x)-f(y){\mid}{\leq}t$ whenever $x{\parallel}y$. In this paper, we determine the range of the fractional weak discrepancy of (M, 2)-free posets for $M{\geq}5$, which is a problem asked in [9]. More precisely, we showed that (1) the range of the fractional weak discrepancy of (M, 2)-free interval orders is $W=\{{\frac{r}{r+1}}:r{\in}{\mathbb{N}}{\cup}\{0\}\}{\cup}\{t{\in}{\mathbb{Q}}:1{\leq}t<M-3\}$ and (2) the range of the fractional weak discrepancy of (M, 2)-free non-interval orders is $\{t{\in}{\mathbb{Q}}:1{\leq}t<M-3\}$. The result is a generalization of a well-known result for semiorders and the main result for split semiorders of [9] since the family of semiorders is the family of (4, 2)-free posets.

Lysyl oxidase (LOX), extracellular matrix enzyme, is catalyzing lysine-derived crosslinks in collagen and elastin. Recently, several LOX-like proteins (LOXL, LOXL2, LOXL3 and LOXL4) have been identified in human but their specific functions are still largely unknown. The purpose of this study was to evaluate the function of the LOX family genes during odontoblastic differentiation of human dental pulp (HDP) cells induced with odontogenic supplement (OS). The messenger RNA (mRNA) expression of LOX family genes and differentiation markers was assessed by reverse transcriptase polymerase chain reaction analysis (RT-PCR). The formation of mineralization nodules was evaluated by alrizarin red S staining. Amine oxidase activity of HDP cells was measured by peroxidase-coupled fluormetric assay. The expressions of differentiation markers, such as alkaline phosphatase (ALP), osteopontin (OPN), osteocalcin (OCN), dentin matrix protein1 (DMP1), dentin sialophosphoprotein (DSPP) in HDP cells were increased after treatment with OS media. The LOX and LOXL mRNA expression were gradually increased in OS media, whereas LOX enzyme activities were markedly detected on day 7. The mRNA expression and LOX enzyme activity of collagen type I was very similar to the pattern of LOX gene. In this study, the expression of LOX and its isoforms, and activity of LOX were highly regulated during odontoblastic differentiation. Thus, these results suggest that LOX plays a key role in odontoblastic differentiation of HDP cells.

Many studies have demonstrated that family plays a crucial role in health and wellbeing in life. There has been little research, however, examining the relative importance of activities together with family members in middle-aged adults. The goal of this study was to examine the effect of family meal, phone conversation with family, and family leisure activities on happiness, health, and family relationship. Total 286 middle-aged adults (M=50.13) participated in this study. Dependent variables were happiness (SWB), physical and psychological illness symptoms, family satisfaction, sex satisfaction, and parenting sense of competence. This research showed that (1) frequency of meal with family was positively correlated with happiness, family relationship, and negatively physical/psychological illness symptoms; (2) high frequency of talking on the phone with family resulted in that high level of happiness, family satisfaction, sex satisfaction, and parenting sense of competence, and lower illness symptoms; (3) the more participants spent leisure time with family, the happier and the more family satisfaction they feel. Findings suggest that activities together with family members in middle-aged adults may enhance their happiness, health, and quality of family relationship. The implication for current study were discussed.

Pregnancies of unmarried women are one of the most serious sex problems because they can negatively affect the lives and development of both unwed mothers and their extramarital children. The number of unwed adolescent mothers is growing recently, extending the seriousness of the problem. This study was conducted to explore the ego-state, life position and family systems that may cause unmarried pregnancy. The data obtained from the structured questionnaire survey of 79 unmarried adolescent mothers and 82 female adolescents were analyzed in terms of frequency and t-test using the SPSS WIN 8.0 program. The results were as follows: 1. Ego-state elements of unmarried adolescent mothers were distributed evenly in general and this falls under the All B(BBBBB) type of ego-gram, just like the adolescents. As for the subject adolescent mothers, CP was the lowest among the 5 egos. 2. As to the life position, the position of "I′m OK, You′re OK"was the highest for both groups, with slight differences. 3. With regard to the family system types sorted by the combination of family cohesion and family adaptability levels, both the adolescent. mothers and adolescents tended to perceive their families as somewhat-balanced or balanced families. 4. While the two groups of adolescent mothers and adolescents showed, on the whole, the same types for all the indicators like above, statistically significant differences were found in more detailed elements.

The study suggests that to compensate for the variety of inhabitants, flexible housing plans are needed. Furthermore, it proposes the support and infill system for the flexible plan of multi-family housing based on the inhabitants need. The inhabitants' need for the flexible plan of multi-family housing was studied using a survey using models. The survey target was the 100 housewives living in a $126.6m^2$(sold as 45 Pyeong) Apartment in Busan. The characteristics of the respondents were first examined, then to figure out the attitude towards the need for the flexible plan of multi-family housing, the concept and preference for the plan, and the satisfaction level of the current apartment plan were analyzed. To find out the structure of the flexible plan of multi-family housing, the need for the structure, furniture, light, and finishing materials were studied. Lastly, to learn the durability of the construction material, the preferred moving period and the reasons were researched. On the basis of the findings, the support and infill system was suggested.

The Purpose of this study was to explore the effects of differentiation, emotion over involvement(expressed emotion), and criticism between middle-or-old aged parent and child, by relation of emotional system, on child's psychological depression. The subject of this study were m premarital adult children over 30 years old. The major findings of this study were as follows. First. it was found that mother-child differentiation was more perceptive than that of father-child. With psychological depression, expressed emotion within family and criticism were shown average score that was lower than middle score. Second, among demographic characteristics, there are significant differences premarital adult children's sex, education, income, family type, father's education, and parents' marital status. Third, as the result of regression analysis, the higher level of psychological depression when the lower differentiation between parent-child, the higher expressed emotion over involvement within family and criticism. Based on the findings in this study, the relation of emotional system is very important. Therefore, it is necessary to consider the therapeutic intervention and relation improvement program when individual and family counseling about parent-child are going on.
