The propose of this study is to grasp actual status and needs of leisure of middle age. The questionnaire survey is used, the subjects are middle age from 40${\sim}$50's living in big city. The questionnaire consists of leisure, leisure actual condition, leisure satisfaction and need. Frequency, percent, average, x2-test, t-test and ANOVA are used for data analysis. The results of this study are as following; First, leisure is necessary to elevate Quality of life in terms of spiritual , psychological stability and physical health. Second, subjects have more leisure time in weekend the characteristics of leisure time are scattered in woman. Third, in the future the subjects wish to have leisure with family.

The article is devoted to the study of the density dependence of the horns tissue on the species and the age of the representatives of the deer family. In scientific literature this problem was covered partially. Basic physical parameters (mass, volume, and density) of horns from red deer (Cervus elaphus), fallow deer (Dama dama), European (Capreolus capreolus) and Siberian roe deer (Capreolus pygargus) were estimated. The present study was designed to analyze the results for making identification of species and age of the animal possible.

Mulberry leaf roller, Diaphania pulverulentalis (Hampson), is a major pest of mulberry, Morus alba. The life table construction from present investigation reveals the age specific survival $(1_{x)}$ and the age specific fecundity $(m_{x})$ of the pest. The female contributed the highest egg production $(m_{x} ＝ 12.75)4 in the life cycle on the $27^{th}$ day and the lowest $(m_{x} = 0.8)$ on the 37$^{th}$ day of the pivotal age. The female progeny production was observed to be intensive for the first six days after the preoviposition period, beyond which it declines steadily, The fecundity of D. pulverulentalis varies between 60-140. The first female mortality within the cohort occurred 4 days after the adult emergence and mortality increased thereafter, One generation is completed in 33.08 days. The female dominated sex ratio (1: 7.18 days) was recorded.

These studies were performed to observe the morphological changes of synapses in the visual cortex of rat during early postnatal development. Specimens of the visual cortex were taken from rats (Sprague Dawley) at 1, 3, 7, 14 and 21 days of age, and prepared for silver impregnation and electron microscopy. The number of synapse and the length of postsynaptic thickening were increased progressively with age, especially 14 and 21 days. The number of dendritic spine was increased conspicuously on postnatal days 14-21. And asymmetic, curved and axo-spinous synapses were increased markedly at the same ages. The present findings suggest that spurt of synaptogenesis in the rat visual cortex occurs during early postnatal development, especially in second to 3rd week period and asymmetric and/or curved axo-spinous synapse is a matured form of synapse with advanced age.

NGC 6716 is an intermediate-age open cluster in Sagittarius. In this paper, we present the new UBV CCD photometry of the stars in the cluster, which is deeper than previous ones. From the color-color diagram and the color-magnitude diagram, we derived a reddening $E_{B- V} = 0.17\pm0.03$ and a distance modulus of the cluster, $(V - Mv)_o = 9.2\pm0.1$. An age of the cluster is estimated as $8\pm10^7 yrs$ from the latest isochrone. Luminosity function and mass function of the cluster are derived. The gradient of the mass function of bright stars is a bit steep, $\Gamma = -1.85\pm0.05$, and there is no distinct bump and dip in the mass function.

The primary purpose of this study was to investigate the validity of a component model of gender role and differences in children's gender concepts with age and sex. The secondary purpose was to investigate the relationship between children's gender schema and memory as well as preference for gender related task. 181 children were interviewed about gender concepts and gender related tasks. Results indicated that three dimensions of the component model (i. e., gender label-component links, within-component links, between-component links) were significantly related to each other. The mean scores of gender role knowledge and attitude were different with age but not with sex. The results of the regression analysis showed that children's age, sex, and gender role attitude explained both memory and preference for gender related tasks. The component model had better explanatory power than the simple model. The findings of the present study suggest that children's gender concepts are better described in terms of the component model than the simple model and may contribute to a theoretical rationale for gender schema theory.

This study aimed to present the tasks to solve digital divide by understanding the actual condition of the digital divide of persons with disabilities in South Korea. Moreover, It is considered that the factors about qualitative digital divide. As a result, it was found that "Information Utilization Capacity" and "Information Utilization" tend to be higher among the young, more often male, higher education level, higher income people who had some information technology education and experience using telecommunication services. In Addition, all failure type affected the "age", "income", "information technology education" in common. Among them, influence of "age" and "information technology education" has become stronger than the other variables. Therefore, in order to solve the qualitative digital divide, it is required to focus as "age" and "information technology education".

The purpose of the present study was to investigate the age-related and encoding-, or retrieval- conditions-related differences in recall and to assess any possible interaction between encoding and retrieval conditions. 108 first and fifth grade children and college adults were presented a 30 item set of pictures for recall it a 2-trial study-test procedure. The data were analyzed in 3(age) x 3(encoding condition) x 3(retrieval condition) x 2(trials) mixed analyses of variance with repeated measures on the last factor. The results indicated the age-related differences in recall and encoding conditions-related differences in recall in the fifth-graders and college adults. Also, the first and fifth grade children's recall was influenced by retrieval conditions. The fifth graders' recall was a function of the interaction of encoding and retrieval conditions.
