This paper investigated children's learning process concerning age and gender, two of the most apparent social roles. The subjects of the study were 72 Korean preschool children between three to five years of age. The Study was designed to examine problems of developmental sequence and horizontal decalage in understanding of these social roles. Two five-step knowledge sequences of age growth and sex constancy were administered utilizing skill theory (Fischer, 1980). Each step in a sequence had different stories of age or sex role with increasing cognitive complexity, but the two sequences were equivalent in complexity. The children were tested under two different assessment conditions:high support condition of elicited imitation and low support condition of free play and the best story. The findings show that, the understanding of age and sex roles develops through the predicted five-step sequences. The understanding of age role seems to develop earlier than that of sex role although the developmental patterns of the two roles are similar. Variations in the children's performances under different conditions were dramatic, especially for the older children.

The purpose of the study is to investigate how childhood attachment and autonomy explain the gender differences in adulthood heterosexual love styles. The study examines (1) the gender differences in childhood attachment and autonomy and adulthood heterosexual love relationships, (2) the relationship between childhood attachment and autonomy in relation to mother, and love styles in adulthood among men and women. 405 married or unmarried men and women participated in a questionnaire study. Such statistic analyses are engaged for this study as cross-tabulation analysis, and one-way ANOVA. The key findings of the study are that the relationships of childhood developmental pattern of attachment and autonomy to adulthood heterosexual love styles differ between men and women. That is, developmental patterns of childhood attachment and autonomy to mother operate as a vulnerability factor in establishing adulthood love relationship, whereas childhood experiences do not explain adulthood love among women. These gender differences are discussed in theoretical contexts which explain gender-differentiated process of separation from mother during childhood.

The new textile materials may be defined as textile materials different from already existing ones in the physical and chemical structure, manufacturing process, or end-use property. The present time what is called the post-industrial society is characterized by rapid change and new technology. Also, textile materials have been changed rapidly and diversely in the post-industrial society than in any other periods. The study aimed to analyze the trend of new tektite materials development in Korea and to forecast the development trend in the future. To investigate the trend of new textile materials, various written materials and informations were collected from the manufacturers, textile related periodicals, and research journals, and they were analyzed. The period of analysis was from January 1992 to May 1995. The results of this research are as followings : (1) Mixed textile materiasl such as bicomponent fiber, blended yam and blended fabric were increased. (2) High technology has an important effect upon new textile material development. (3) functional textile materials were increased (4) The high value-added products were increased. (5) The naturalized textile materials were increased.

The olfactory bulb (OB) has an extremely higher proportion of interneurons innervating excitatory neurons than other brain regions, which is evolutionally conserved across species. Despite the abundance of OB interneurons, little is known about the diversification and physiological functions of OB interneurons compared to cortical interneurons. In this review, an overview of the general developmental process of interneurons from the angles of the spatial and temporal specifications was presented. Then, the distinct features shown exclusively in OB interneurons development and molecular machinery recently identified were discussed. Finally, we proposed an evolutionary meaning for the diversity of OB interneurons.

Purpose: The purpose of this study was to understand the process of exercise adherence in middle aged women. Methods: The qualitative theme analysis method was used. The participants were 11 middle-aged women who had exercised over 6 months. Data were collected through in-depth interviews and recorded by and transcribed immediately. The data were coded with similar meaning and analysis themes with the constant comparative method. Results: The core theme was Stepping Stones Across the Stream (SSAS). The Stone means the adherence factors in exercise. The stream means the interrupting factors in exercise adherence. The subcategories were 1) feeling of developmental crisis, 2) searching for exit (from the developmental crisis), 3) finding a surprising new world (full of fun), 4) confronting the situation of dropout, and 5) adherence to exercise by SSAS. Conclusion: The predisposition of fun in middle aged women for the adherence of exercise should be explored along with more adherent factors.

The purpose of this study was to analyze the characteristics of the pre-design of brownfield's by comparing LDA, EPA, and BRA of UK and USA in terms of establish mainbody, brownfield information, development process, opening development information. Such analysis will generate important implications for the development and renewal of brownfield in Korea by gaining insights into the characteristics of brownfield that reflect systematic and effective management and planning for urban renewal. The findings from this study indicate that: 1. Information on brownfield plays an important role at the development and planning stages that precede architectural design. 2. There is a great need for organizations that are responsible for brownfield renewal, such as LDA of UK, EPA and BRA of USA, in Korea, to make information public and to practice systematic management. 3. Discussion on the pre-design that follows contamination and renewal of brownfield and the developmental strategies that satisfy both the developmental and public profits are warranted.

Procambium developed in the histogenetical zone below the marginal meristem. The development of procambium is correlated with the developmental stage of the leaf. As long as the marginal cells are crescent-shaped, the first-order procambium develops. When the marginal cell becomes wedge-shaped, the higher order procambium appears. The reticulated venation is developed through forking and anastomosis. The meshes of the first order enlarge in the process of leaf growth and the meshes of the second and third order develop in the meshes of the first-order through the differentiation of the residual meristem. Therefore, the venation is hierachically arranged and is as recognizable from the thickening of the veins. The outermost vein is produced parallel to the leaf margin, in which the differences between the costal and intercostal parts of the marginal meristem are removed. The endodermis and pericycle differentiate from the same mother cell. The procambium and sclerenchyma originate from a common source during the first developmental stage. A small cellular cluster lies within the parenchyma at the upper and lower sides of the procambial trace and differentiates into sclerenchyma.

Given that the number of people with developmental disabilities is continuously increasing in Korea, we need to pay attention to the lives of parents who rear the children with developmental disabilities. Accordingly, this study examined the effects of parenting stress on the quality of life in parents of children with developmental disabilities, and moderating effects of information application in the process. This study conducted a survey to 194 parents who rear such children in Chungnam and Chungbuk provinces. This study utilized PASW Statistics 18.0 for analysis, and the study results are as follows. First, it was found that parenting stress was more than average level, and information application was somewhat lower than average level. Quality of life was found to be lower than average level, and the level of relationship with neighborhood and emotional condition was relatively lower than other sub-factors. Second, influential factors of life quality were parenting stress, disability degree, information application, residential area, and disability type. Third, information application was found to have moderating effects on the relationship between parenting stress and quality of life. Based on such empirical analysis results, this study suggested concrete and comprehensive working strategies to improve quality of life in parents of children with developmental disabilities.

In research on behavioral studies, significant attention has been paid to the stage-sequential process for multiple latent class variables. We now explore the stage-sequential process of multiple latent class variables using the multivariate latent class profile analysis (MLCPA). A latent profile variable, representing the stage-sequential process in MLCPA, is formed by a set of repeatedly measured categorical response variables. This paper proposes the extended MLCPA in order to explain an association between the latent profile variable and the latent group variable as a form of a two-dimensional contingency table. We applied the extended MLCPA to the National Longitudinal Survey on Youth 1997 (NLSY97) data to investigate the association between of developmental progression of depression and substance use behaviors among adolescents who experienced Authoritarian parental styles in their youth.
