The family tree is one of the key elements of humanities classics research and is very important for accurately understanding people or families. In this paper, we introduce a method for automatically generating a family tree using information on interpersonal relationships (IIPR) from the Korean Classics Database (KCDB) and visualize interpersonal searches within a family tree using data-driven document JavaScript (d3.js). To date, researchers of humanities classics have wasted considerable time manually drawing family trees to understand people's influence relationships. An automatic family tree builder analyzes a database that visually expresses the desired family tree. Because a family tree contains a large amount of data, we analyze the performance and bottlenecks according to the amount of data for visualization and propose an optimal way to construct a family tree. To this end, we create an n-ary tree with fake data, visualize it, and analyze its performance using simulation results.

This research paper is applying Family Tree with Story Authoring System on the previous research study about writing tool data model on interactive storytelling about family history. In this study, primary personal information holding identity of the person such as name, birthday and family tree, given at birth, was categorized into secondary function defined as "family contents" consisting of family achievements, episodes and experiences. Family contents was restructured to be used as creative ingredients to increase the value and usage of family contents...Family Tree with Story writing system enables users to create text, images, videos and digital contents based on experimental knowledge collected from the first and second generations.

Hierarchical tree routing is a inefficient routing method of transmitting data in a wireless sensor network. Zigbee routing which is made to improve inefficiency of the hierarchical tree routing only fulfills the tree routing when a destination node don't exists in neighbor nodes of a router. We suggest a TFSR algorithm that is improved more than the zigbee routing. The TFSR algorithm generates a family set included a parent node and child nodes and over of a destination node, and uses this information. According to simulation results, the TFSR algorithm reduce routing costs over 30 percent in comparison with the hierarchical tree routing and the zigbee routing.

The objectives of this study were to examine the genetic variation of 20-year-old tree height and to estimate heritabilities and genetic gains of Korean white pine. Analysis of variance showed that families and family x block interaction had the significant (p=0.01) effects on tree height. However, family variation appears to be much greater than the variation due to family x block interaction. Individual tree heritability was higher ($h_I^2=0.73$) than family heritability, ($h_F^2=0.83$) therefore, combined selection showed the largest genetic gain (17.76%) in a given equal intensity of selection.

Objectives : The purpose of this study is to report the concept of familial scoliosis through eight cases. Methods : The family tree was constructed with eight cases which was diagnosed idiopathic scoliosis by physical examination and radiological study. Results : According to the family tree of this sibs, idiopathic scoliosis apparently behaves as an autosomal dominant inheritance. As to parents and grandparents, although they are not confirmed the appearance of idiopathic scoliosis, we know that they transmit trait to their descendants as a genotype. Conclusions : This study is shown that idiopathic scoliosis has a familial condition and provided useful information that can be used early diagnosis and treatment with screen tests based on the family tree.

The purpose of this study was to verify whether BND test was an appropriate tool for diagnosis of attachment security and to investigate difference of responsive Characteristics to the Bird's Nest Drawings according to parents attachment degree. The subjects in the study were 525 students, selected from senior high schools in D-city. The instruments used were parents attachment scale and Bird's Nest Drawings, and Discriminant analyses and crosstab analyses were used. The results were as follows. First, attachment indicators in the Bird's Nest Drawings discriminated according to group of parents attachment. Second, for male student, there was a significant difference placement nest, eggs, entire birds family, quality of line and tree picture according to attachment to father. For female student, there was a significant difference eggs, entire birds family, quality of line and tree picture according to attachment to father. For male student, there was a significant difference nest contents, placement nest, eggs, entire birds family, quality of line and tree picture according to attachment to mother. For female student, placement nest, space, nest size, eggs, entire birds family and quality of line according to attachment to mother.

The group Steiner tree problem is a generalization of the Steiner tree problem that is defined as follows. Given a weighted graph with a family of subsets of nodes, called groups, the problem is to find a minimum weighted tree that contains at least one node in each group. We present some existing and some new formulations for the problem and compare the relaxations of such formulations.

The purpose of this study was to verify the usefulness of kinetic House- Tree- Person drawing as a diagnostic measure for the degree of self-differentiation, which is an essential part of college students' development. Participants for the study were four hundred thirty five(272 male and 163 female) university freshmen enrolled in 4-year colleges located in Pusan. The Participants completed a scale of self-differentiation and a Kinetic House- Tree-Person drawings test. The evaluation system for kinetic House-Tree-Person drawings was established based on the indexes of Buck(1948) and Bums(1972) and used exiting literatures as reference. The data were analyzed using means, standard deviations, t-test, one-way ANOVA, and Scheffe's test. The results obtained from the study are as follows: First, the mean level of college students' self-differentiation was 2.81, which is about average. Some significant gender differences were found in the areas of self-intergration, family projection, and emotional separation. Male students scored higher on self-intergration, whereas female students score higher on family projection and emotional separation. Second. self-differentiation was higher when the student drew a house with smoke coming out of the chimney, a single-story house with flat roof, or with detailed description of curtains, roof and roof tiles. Third, self-differentiation seemed to be higher when branches and fruits were included, when there was no expression of roots, when large crowns and branch openings were presented, and when no slant lines or base lines appeared. Forth, self-differentiation showed ㅁ higher level when the portrait shows eyes, mouth and neck without omission, when it included the whole body instead of face only, and when there was no person with just a profile, a back, or with a stiff posture, and when there was no weak and thin lines. Individuality also marked higher if a person was in motion and than one person was added. Finally, self-differentiation showed significant difference according to the overall harmony of the drawing, ordering of contents, hand pressure, the kind and shape of tree, and presence of other persons. The more harmonious the picture was, and the more family members are added, the higher the level of self-differentiation was.

In a series of original papers, [1-17] efficient methods and algorithms have been presented, for the exact solution of many reliability problems represented by binary networks. A starting point of these methods was the concept of domination, firstly introduced in ,elation with reliability problems in [2]. It's application to directed networks resulted in the development of a topological formula for the classical problem of the two terminal reliability. This result was extended later to the all-terminal and the k-terminal reliability problems. All papers mentioned above use a path oriented representation for the network topology. In practical applications, however, it is common and often advantageous to work with cut sets. This article considers the Domination theory for reliability problem of a network. Some topological formula are derived and the power and the application of this formula are shown through the alternative proof of topological formula of A. Satyanarayana [2].
