The purpose of this study was to identify the relative influence of OCM and BSM's family functioning dimensions and develop a new family system model related to adolescent adjustment. The 443 subjects were selected randomly from the second grade of middle and high schools in the city of Taegu. The survey instruments were FACESⅢ, SFI-Ⅱ, State-Trait Anxiety Inventory, Depression Scale, Self-Esteem Scale, and Delinquency Scale, Factor Analysis, Cronbach's α, Multiple Regression, MANOVA, Scheffe test were conducted for the data analysis. The major findings of this study were as follows: First, OCM's and BSM's family functioning dimensions respectively had different relative influence that affected adolescent adjustment level. In anxiety and depression. BSM's family health/competence dimension had superior influence to any other family functioning dimensions and in self-esteem and delinquency, OCM's cohesion dimension was superior to any other family functions. Second, family system classification method by a new family system model using family cohesion(OCM's relationship dimension) and family health/competence(BSM's change dimension) was more useful than OCM in evaluating adolescent adjustment.

A recursive family $\{F_n\}$ of holomorphic functions on the Riemann sphere is defined and some elementary properties of this family is described. Then the Julia set of $F_n$ is computed. Finally this family as a real recursive family is studied and it is shown that $F_n$ is chaotic on a specific subset of $\mathbb{R}$.

This study has investigated the perception of adults in relation to healthy family to help identify import issues. Gathered information were then incorporated to education programs for the Healthy Family Support Center. For this purpose, a survey was conducted in four cities in Kyungnam during March 2007. The responses of 213subjects have been used for the final analysis. The results of this analysis lead to three major findings. Firstly, the surveyed adults regarded positive interaction and domestic family functions as essential activities in healthy families. Secondly, the participants exhibited a very low knowledge-level of the 'Healthy Family Act', and the Healthy Family Support Center. Finally, the respondents said that they are more likely to specifically participate in educational program and counseling program if it helps them prevent family programs.

This study was examined about consciousness and actual service, functions of ancestral rite in modem society. In order to study, the questionnaires for 401 university students were used and personal interviews with 14 as 7 female,7 male. Data were analyzed using the SAS programs. The main results of this study were as follows: The male's consciousness and actual service was significant higher than female's about the traditional ancestral rite. The religion was affected significant variable in ancestral rite. When the family hold many performs and students are participate in ancestral rite many times, they are positive about traditional ancestral rite. On the functions of ancestral rite the students thought the ancestral rite influenced family members and relatives to promote mutual family membership.

We will construct polynomials of degree 6 in z and $\bar{z}$ on $C^2$ which gives, via its coefficient $\beta$ as a parameter, a family of pseudoconvex domains $\Omega_\beta$ in $C^2$ with the origin being a boundary point, and show that the domains $\Omega_\beta$ has no peak functions of class $c^1$ at the origin and has no holomorphic support functions for $1 \leq \beta < \frac{9}{5}$.

Let A be a normed space, ${\mathcal{B}}(A)$ the algebra of all bounded operators on A, and V a family of strongly upper semicontinuous functions from a Hausdorff completely regular space X into ${\mathcal{B}}(A)$. In this paper, we investigate some properties of the weighted spaces CV (X, A) of all A-valued continuous functions f on X such that the mapping $x{\mapsto}v(x)(f(x))$ is bounded on X, for every $v{\in}V$, endowed with the topology generated by the seminorms ${\parallel}f{\parallel}v={\sup}\{{\parallel}v(x)(f(x)){\parallel},\;x{\in}X\}$. Our main purpose is to characterize continuous, bounded, and locally equicontinuous weighted composition operators between such spaces.

The part family (PF) formation in a cellular manufacturing has been a key issue for the successful implementation of Group Technology (GT). Basically, a part has two different attributes; i.e., design and manufacturing. The respective similarity in both attributes is often conflicting each other. However, the two attributes should be taken into account appropriately in order for the PF to maximize the benefits of the GT implementation. This paper proposes a clustering algorithm which considers the two attributes simultaneously based on pareto optimal theory. The similarity in each attribute can be represented as two individual objective functions. Then, the resulting two objective functions are properly combined into a pareto fitness function which assigns a single fitness value to each solution based on the two objective functions. A GA is used to find the pareto optimal set of solutions based on the fitness function. A set of hypothetical parts are grouped using the proposed system. The results show that the proposed system is very promising in clustering with multiple objectives.

The purpose of this Study is to theoretically discuss the Family Business. Family Business means a business that is owned and managed by one or more family members. Family Businesses are seen as an avenue to achieve economic security, as motivations for a productive society, and as a method for individuals to receive a monetary return for their talents and initiative. The presence of family business as a predominant business structure in the all of country's economy and their association economic contributions have been documented elsewhere. The overall objectives of this study are to introduce in the Home economics and Home Management field what the Family Business is, concretely to identify the definition of Family Business and related concepts-Home Based Business & Home Based work-, to study the interface of family and business functions within a single family. This study is to examine a clear understanding of the relationship between family functioning and business viability in families who own and operate businesses. Such understanding will be helpful in enhancing the stability and security of families who own and operate business and in developing policies and programs that foster Family Business and assist in their contributions to community and economic development. Also to understand the family and business environments and their interaction can enhance the opportunities and satisfactions for family members who are involved in business together. Results from this study will allow researchers a unique view of the Family business management and will contribute to individual and group well-being in both family and work settings.

In this paper we obtain average of class numbers of some family of Artin-Schreier extensions of rational function field ${\mathbb{F}}_q(t)$, where q is a power of 3.
