Moving object management is widely used in traffic, logistic and data mining applications in ubiquitous environments. It is required to analyze spatio-temporal data and trajectories for moving object management. In this paper, we proposed a novel index structure for spatio-temporal aggregation of trajectory in a constrained network, named aCN-RB-tree. It manages aggregation values of trajectories using a constraint network-based index and it also supports direction of trajectory. An aCN-RB-tree consists of an aR-tree in its center and an extended B-tree. In this structure, an aR-tree is similar to a Min/Max R-tree, which stores the child nodes' max aggregation value in the parent node. Also, the proposed index structure is based on a constrained network structure such as a FNR-tree, so that it can decrease the dead space of index nodes. Each leaf node of an aR-tree has an extended B-tree which can store timestamp-based aggregation values. As it considers the direction of trajectory, the extended B-tree has a structure with direction. So this kind of aCN-RB-tree index can support efficient search for trajectory and traffic zone. The aCN-RB-tree can find a moving object trajectory in a given time interval efficiently. It can support traffic management systems and mining systems in ubiquitous environments.

Rearing is important to the growth and development of the child. Traditionally, nurturing is a maternal role which is expressive role. Maternal role was composed of mothering and maternicity. Rearing is a key concept of psychology, education and sociology discipline. Knowledge of the rearing is an essential component for the development of nursing as a science and a profession. The first thing to study a concept is thought to be a concept analysis. So, in this study, concept analysis of the rearing was performed to clarify a concept of the rearing as a basis for the study of rearing afterward. The approach used for the concept analysis was the approach presented by Walker and Avant (1993). The defining attributes of rearing, identified in this study were (1) a series of caring activities in parent-child relation, (2) an essential of the growth and development of a child, (3) changeable according to time, place and object, (4) effort is necessary to the rearing, (5) positive or negative aspects (6) attitude, behavior, environment is sub-concepts of the rearing concept. The identified antecedents of the rearing was child-birth. The identified consequences of rearing were desirable or undesirable outcomes. Desirable outcome was the emotional satisfaction and growth in parent-child relation. Undesirable outcome was the emotional disorder and social maladaptation of the child. The empirical referents of the rearing could be the caring phenomena in parent-child relation.

In becoming parents, the marital partners enter into a new developmental phase. The conception of the child is an act of mutual creativity during which the boundaries between the self and another were temporarily obliterated more completely than at any time since infancy. The infant is a physical fusion of the parents, and their personalities unite within the child. for many women, creativity as a mother becomes a central matter that provides meaning and balance to their lives. The husband usually has strong desires for an offspring and can be transformed by it. The child can profoundly affect one or both parents, and the influences are reciprocal-a child's needs or specific difficulties uncover a parent's inadequacy. following the child's development, each transition into a new developmental phase requires an adaptation by the parents, and one or another of these required adaptations may disturb a parent's equilibirium. And the personality changes, emotional difficulties, and regressions of a spouse that occur in response to some phase of parenthood can upset the marriage. Not only do children identify with parents, but parents also identify with their children. The parents take pleasure in child's joy and suffer with the child's pain more than in almost any other relationship. certain respects e parents lives again in the child. Through the process of identification the child can also provide one of the two parents with the opportunity to experience intimately the way in which a person of the opposite gender grows up. Parenthood also provides the opportunity to be loved, admired, and needed simply because one is a parent and, as such, a central and necessary object in the young child's life. The many potentialities for emotional satisfactions from parenthood manage to outweigh the tribulations and sacrifices that are required. The child also exerts an indirect effect through changing the parent's position in the society, for new sets of relationships are established as the parents are drawn to other couples with children of the same age, and for a new impetus toward economic and social mobility often possesses the parents. frequently the couple's relatedness to their own parents improves and grows firmer once again. Parenthood, the satisfactions it provides and the demands it makes, varies as life progresses : and changes with the parent's interests, needs, and age as well as with the children's maturation. There are phases in the child's life that the parents are reluctant to have pass, whereas they tolerate others largely through knowing that they will soon be over. The changing lives of the children provide many satisfactions that offset the tribulations, uncertainties, and regrets. The parents change. The young father, who was just starting on his carrier whom the first child was born, settles into a life pattern. He becomes secure with increasing achievement and interacts differently with the youngest child and provides a different model for him than for the oldest. The mother may have less time for a second or third child than for her first, but she may also be more assured in her handling of them. The birth of a baby when the parents art in their late thirties will find them Less capable of physical exertion with the child and less tolerant of annoyances, but they are less apt to be annoyed. Eventually the children min and leave home, but the couple do not cease to be parents.

The object of this research was to examine closely through the document about how much important location Sanhoopoong had and how it influences in the women's health. In addition to that, from the result of this research. I would like to contribute to korean nursing theory development and korean traditional nursing. Sanhoopoong is only the pain of women, come out to whom experienced delivery and abortion and especially it is an important cultural disease to Korean women. This is, once be taken ill, even reputed doctors cannot cure, so this make women suffer from pain, fall ill, decrease the quality of women's life, and it is appealed by women constantly, and is just made known by traditionally. The cause of Sanhoopoong has not been recognized medically The disease is not included in the disease classification. Thus, Sanhoopoong has no special pathological cause, and because it is the desease when be not taken care after childbirth, so this is able to be prevented and relieved sufficiently. But Sanhoopoong is the important health matter to dominate women's whole life's health. It has to be researched and lightened quikly. We have to help the women to get out of the difficulties from the pain of Sanhoopoong as soon as possible.

The object of this paper is to evaluate SCC(stress corrosion cracking) susceptibility for parent metal and bond line region of weld joints which have the various weld heat input condtions in TMCP(thermo-mechanical control process) steel by SP-SSRT(small punch-slow strain rate test) method. And the SCC test results of TMCP steel are compared with those of the conventional HT50 steel which has te almost same tensile strength level like TMCP steel. The loading rate used was $3\times10^{-4}$mm/min and the corrosive environment was synthetic sea water. According to the test results, in the case of parent metal, TMCP steel showed higher SCC susceptibility than HT50 steel because of the high plastic strain level of ferrite microstructure obtained by accelerated cooling. And in the case of bond line, the both TMCP steel and HT50 steel showed low load-displacement behaviors and higher SCC susceptibility above 0.6. These results may be caused by theembrittled martensite structure on HT50 steel and by the coarsened grain and the proeutectoid ferrite structure obtained by the impart of accelerated cooling effect on TMCP steel.

Purpose I investigated how beliefs in punishment have influence on child abuse. Also, I investigated how socio-demographic variables of parents' have influences on child abuse by parents. Sampling was conveniently and total 160 parents replied to the study. Data analysis was done by descriptive statistics, Pearson's correlation using SPSSWIN. The results were as follows. Mild child abuse: 'Throwing the object at me(21.1%)', 'Clutching, and pushing (21.0%)', 'Slapping on the cheek (19.1 %), Severe child abuse: 'Kicking, pounding and biting(4.1%)', 'Rod, stick, belt, broom beating using a various objects such as(51.7%)', 'Beating all over the body(6.8%)'. Very severe child abuse: 'Burning with cigarette (0%)', 'Threatening me with a knife, a hammer, a naxe, a gimlet the objects such as(0.7%)', 'Injuring me with the objects such as (0%)', 'Hospitalized by belting(0%)'. Correlations of major variables were as follows. Physical child abuse by elementary student's parents has significantly positive correlation with beliefs in punishment(r= .244 p= .003) and has significantly negative correlation with parent's age(r=-.273, p=.001). But physical child abuse has not significant correlations with family income, education. Conclusion: Beliefs in punishment of parents have influences on child abuse. To prevent child abuse, effective parenting program development is required.

The purpose of the current study is to examine the role of mothers' personality traits in predicting their parenting stress. The study subjects were married working woman who live at Gyeonggi-do and has their first child studying in elementary, middle, or high school. Collected data were analyzed with SPSS WIN 18.0 program. The results were as follows.: First, it has been shown through examination of the general tendency of observation subjects' relative factor, that many have above average parenting stress. The compositing factor for parenting stress were mainly the burden and distress of the parent role. Second, the differences in parenting stress were affected by relative variables in accordance with the general features of the study object. If the younger the parent, the higher the education, the lower the age of the first child, and if there were a child assistant after school, the parenting stress became larger. Third, after controlling for demographic characteristics, employed mothers' neuroticism significantly predicted greater parenting stress. When mothers had more conscientiousness and openness, they reported less parenting stress which implied that interpretation and perception of child rearing experiences can vary depending on personality and predict parenting stress of working mothers.

Objectives: Humans experience the process of separating-individuating themselves from an object via the conflict between dependence and independence within the self. The separation-individuation theory focuses on the psychological process of individualizing oneself. Although adolescents' individuation from their parents is based on intrapsychic events, there is an increasing need for an intersubjective understanding of it. We applied intersubjectivity to adolescents and parents to interpret and find solutions for problems arising during their individuation process. Methods: This study retrospectively reviewed a case of a son and his father treated by the author. From the study subject, contents that represent adolescents and parents' interaction and separation in the individualization process were extracted and analyzed, and their experiences shared in this process were reconstructed from the therapist's perspective. Results: From the case involving an adolescent boy with conduct problems and his interactions with his father, the authors observed the phenomenon of intersubjectivity and proposed the concept of "synchronized individuation" between adolescents and parents. As adolescents rapidly grow and change, they experience various dynamic interactions with their parents. Through learning to tolerate the conflicts and ambivalent tension inherent in this individuation process, adolescents and their parents develop their new identity. Conclusion: "Synchronized individuation" should be understood as complementary to, rather than exclusive from, the existing concept of the separation and individuation. It offers a new paradigm with which to understand adolescent-parent conflicts in the process of separation-individuation.
