We have developed a method to evaluate pumping rates from a system of pumping-well family. For a given system actual pumping rates depend on pump characteristics and the sum of the static head and the dynamic head. The static head is the elevation difference between the natural groundwater level and the outlet of the pipeline that connects all the wells. Major components of the dynamic head are groundwater drawdown in the well and pipeline head loss. The dynamic head and the pump characteristics depend on the pumping rates. Actual pumping rates are determined at the intersections of the system total-head curves and the pump characteristic curves. The Newton-Raphson's method is used to solve the nonlinear simultaneous equations. The method is applied to a hypothetical well family. Impacts of various design and operational parameters on the pumping rates are analyzed.

Purpose. This study examines the effects of improving students self-esteem and sociability by conducting a Group Art Therapy Program for students with learning disabilities. This study focused on three students with learning disabilities, attending B middle school special education class located in K county. The study was conducted for two hours once a week (Friday) at B middle school during special education class from May 2, 2014 to July 18, 2014. Methods. For the tools of studying, Self-esteem and social strip forms/rubrics were filled, by students', before and after and data processing was inspected, paired t-Test using the SPSS / WIN (Ver.18.0) for quantitative analysis. Also, on the basis of content, analyzed data of the individuals' self-esteem social changes are shown in graph format. In addition, this qualitative study shows before and after of dynamic house, tree, person (K-H, T, P), dynamic family (KFD), dynamic school life of search phase (4-6 sessions) significant improvement of self-esteem and sociability in adolescents' with learning disabilities influenced by conducting a Group Art Therapy Program. Results. The result of this study can be summarized as follows. First, Group Art Therapy Program shows a statistically significant difference (p<.05) showing that self esteem average is 2.04 before Group Art Therapy Intervention but self esteem average is 2.92 after Group Art Therapy Intervention. Second, as a result of social strip pre-post, there wasn't statistically significant difference compared to self esteem pre-post result, although, post examination's average level was enhanced after Group Art Therapy Program in difference examination.(p>.05). Third, as a result of analysis the indicated pre-post change of Students' pre-post dynamic house, tree, person (HTP), dynamic family (KFD), a dynamic school daily life (KSD), students' family and interpersonal relationships, self-concept shows statistical significant changes. Conclusion. As the result of this study, Group Art Therapy Program shows effective improvement in students' self-esteem and social skills learning disabilities. However, a future study on larger and more diverse group of students' with learning disabilities are advised to be conducted in order to better understand the significance of the Group Art Therapy Program.

The purpose of this study was to clarify what's the middle-aged experience until now and what's the middle-aged women shed light on their life. The phenomenology study design was used and Giorgi method was used for this analysis. We selected 7 middle-aged women for this study such as 2 professor, 1 dentist, 1 own-business woman, 1 house house wife, 1 Nurse, and 1 farming woman. The result of this study were as followers; there were 7 structure factors such as 'poor family economic status', 'meaning of family-of-origin', 'dynamic social experience', 'marriage', 'heartrending', 'getting feeling of aging', and 'focus of life'. According to the results of this study, the participants who were more positive feeling of their poor family status, they were more becoming professional job in the adult age. And they shed light on their life with spirituality through the dynamic social experience, marriage, and heartrending. Therefore we suggest that right spiritual program for the better old aged time for them.

This study analyzes the effects of women's labour force participation and work-family reconciliation support on life-cycle fertility in Korea. The analysis is based on the longitudinal data from Korean Labour and Income Panel Study (KLIPS), which include the available information on life-cycle fertility and employment history. Employing a dynamic model of fertility, we estimated the life-cycle fertility of all the 15-49 years old women considered in this study by using a duration model. The major results of this study were as follows: First, women's labour force participation had a negative effect on the first birth, second birth, and all births (transition to births starting at different parities). Women's employment tended to lengthen the interval between births. Second, the availability of maternal leave had a positive effect on the first birth and all births for working women. Providing maternal leave to working women decreased the opportunity cost of childbearing and in turn, reduced the interbirth interval of women. However, the availability of parental leave had no significant effect on the births of working women. Third, the financial support for childcare had a positive effect on the first birth and all births. The economic support for childcare led to the reduction in the interbirth interval of women by increasing the probability of births. The use of a childcare center for the first child, which substitutes for the time that women needed to take care of their children, classified as time-intensive consumption goods, did not have any effect on the second birth. Fourth, the part-time employment of women had a positive effect on the second birth. A flexible working time schedule tended to decrease the interval between the first and the second births.

The purpose of this study is to develop and verify the effectiveness of a group art therapy program to help children from multicultural families adapt to school life by using Kinetic School Drawing(KSD). The result of this study showed that the group art therapy program of the multicultural family's children may have a positive effect in aiding their school life adaptation. The results showed considerable and statistical outcome in the fore and after drawing inspection of the dynamic KSD. Also, the size of the self-image became bigger and their expressions has been increased. The qualitative analysis also showed a huge change in dynamistic personal relationships due to the relationship with their peers with the same aged and the tutor. This study emphasizes the importance of the group art therapy program to be applied before children are admitted to school because of growing recognition of concern about the maladjustment of rapidly growing multicultural family's children. It is also suggests that the group art therapy program of growing multicultural family's children should be viewed with an ecological point of view.

Although the family methods with unconditional stability and numerical dissipation have been developed for structural dynamics they all are implicit methods and thus an iterative procedure is generally involved for each time step. In this work, a new family method is proposed. It involves no nonlinear iterations in addition to unconditional stability and favorable numerical dissipation, which can be continuously controlled. In particular, it can have a zero damping ratio. The most important improvement of this family method is that it involves no nonlinear iterations for each time step and thus it can save many computationally efforts when compared to the currently available dissipative implicit integration methods.

While economic incentives have led to migration, the failure to adapt to a new city and to ease the financial burden to support families have raised migrants' intention to return to their hometowns. Using the 2016 China Migrants Dynamic Survey, this study investigates determinants of migrants' intention to return. Migration at a young age, which is associated with lower barriers to the new culture, and intraprovince migration requiring less effort to adapt to the new city, were associated with lower intention to return. Also, migrants with less burden to support a family tend to have a higher intention to return to rural hometowns. Specifically, migrants with children over 18 years old and fewer family members are likely to return to their hometowns. To revitalize rural economy and reduce the rural-urban disparity, a policy to support migrants with high intention to return will be needed.

The purpose of this study is to explore the family communication and power. Communication is a symbolic, transactional process in functional view . To say tat communication is a process implies a continuous interaction of an indefinite large number of variables with a concomitant, continuous change in the values taken by these variables. Finally the process implies change. Family functions include the primary functions of cohesion and adaptability and supporting functions of family images, themes, boundaries, and biosocial issues, The primary functions reveal concepts integrated family interaction and supporting functions, along with those of cohesion and adaptability, give shape of family life. The message system is the major element of communication process and influences both the form and the content of thier relationship and create and share meanings. The family-of-origin issues influence all aspects of family communication and account for many of the communication patterns, rules and networks. Power does not belong to an individual. rather it is a property of a relationship between two or more persons, Power, a system property is the ability of an individual to change the behavior of other members in a social system. Power operate transactionally in a family and any power maneuvers within it have a system wide effect. In order to study power in families , it is necessary to examine 1) family power operations 2) development of family power and 3) the communication of power strutegies. The research presented indicated that a rigid power structure, characterized by dominance and little sharing, restricts family flexibility reduce cohesion, and adversely affects satisfaction in families. power constantly changes as a family grows and develops within its system. Although power changes may be more obvious in children as they mature and more from a independent stated to an independent one, each of the parents experience egual or greater. Communication and activities take place that either enhance positively or negatively the images, themes, and degree of unity of cohesion the family desires. Power operated within a dynamic, growing, changing, interdependent transactional family system. Power struggle may develop when as issue becomes important to one or more family member. When this happens, and the rational exploration of alternatives ceases, various one-up power maneuvers usally follows, This affect family intimacy. a vital element in meaningful relationships . To resolve differences and not become the victim of another's power , one need to engage in constructive conflict since the ability to clearly and comfortably repudiate another is part of the achievement of intimacy.
