The purpose of the present research was to study developmental trends in and relationships between recall, organizational strategy, and metamemory in young children. The subjects were 84 children, 14 boys and 14 girls at each age level, 4, 6, and 8. Two tasks (memory task & metamemory task) were used to assess children's recall, organizational strategy, and metamemory based on Sodian et al.(1986). All subjects were randomly assigned either to the play-and-remember condition or to the sort-and-remember condition. The two tasks were administered to children individually with the memory task followed by the metamemory task. The data were analysed by the statistical methods of two-way ANOVA, Student-Newman-Keuls post hoc test, Mann-Whitney U test, Kruskal-Wallis test, Pearson's correlation coefficient and Kendall's Tau. Children's recall (free, conceptually-cued, and perceptually-cued) level increased with age. There were significant experimental condition differences in free recall and conceptually-cued recall, but not in perceptually-cued recall. Children's organizational strategy showed differential developmental trends by experimental condition. Use of conceptual strategy at both encoding and retrieval increased with age in both experimental conditions. Use of perceptual strategy (PS) at encoding showed an inverted-U age effect in the play-and-remember condition, but PS decreased linearly with age in the sort-and-remember condition. There were significant age differences in metamemory, and there were significant correlations between recall and organizational strategy.

Self-thinning was measured in Salix communities on Bam Island in Seoul at various age stages. $D^2H$ was used to estimate tree biomass, where D is stem diameter at breast height or 10 cm height for plants with height <1.5 m, and H is height. A log-log plot of density versus $D^2H$ and correlation analysis indicated a significant relationship between density and biomass with equation 'log $D^2H$ = -1.27 log N + 7.06'. This indicates that self-thinning affects biomass in the Salix community with -1.27 as the thinning coefficient. If we assume a thinning exponent -3/2, then the allometric coefficient of the equation, log w = a log $D^2H$ + b, is 1.18. This is much higher than that for any other species studied in Korea. There were statistically significant relationships between age and density and between age and basal area and these relationships suggest guidelines for transplantation of willows and for the assessment of Salix community restoration projects in riverine wetlands based on standard density, basal area, and age. The results of this study may also increase understanding of succession processes in Salix community restoration in riverine wetlands.

Purpose: This study aimed to identify the relationships of superior's leadership to supervisory trust and organizational commitment of nurses. Method: Subjects were 386 nurses in 8 general hospitals at G city and Seoul. Data were collected with self-administered questionnaires and analyzed using SAS 8.12 by applying ttest, ANOVA, Pearson correlation coefficient, and Stepwise multiple regression. Results: Superior's transformational leadership was $3.54{\pm}0.53$ and transactional leadership was $3.40{\pm}0.36$. Supervisory trust was $3.14{\pm}0.46$ and organizational commitment was $3.18{\pm}0.53$. Superior's transformational leadership was positively correlated with transactional leadership, supervisory trust and organizational commitment with each others. The level of supervisory trust and organizational commitment were different significantly by age, educational status, clinical career, position and superior's leadership level. Major factor that affect to supervisory trust and organizational commitment of nurses was transformational leadership, which had an explanation of 45.9% and 29.8%. Conclusions: The more nurses perceived the superior's transformational leadership, the higher nurses perceived supervisory trust and organizational commitment. Therefore, these variables generally screened and other factors should be analyzed. And if specified nursing intervention program which increase superior's transformational leadership will be developed, it may contribute to strengthen the effectiveness of nursing.

This descriptive-correlational study was undertaken in order to examine if there were relationships between family support, compliance and life satisfaction in chronic arthritis patients. The sampling method was a non-probability, purposive sampling technique. The participants of this study were 92 volunteer adults. 1) who have been diagnosed as having chronic arthritis and 2) who were at the medical out patient clinic of one university hospital in Seoul between April 27th to May 12th 1987. The instruments used for this study were the Family Support Scale developed by Kang Hyun Sook, a Compilance Scale developed by the researcher and the Life-Satisfaction Index-Z developed by Wood et.al. Analysis of data was done using t-test, ANOVA, Pearson Correlation Coefficient and Stepwise Multiple Regression Analysis. The results of study were as follows; Hypothesis I; “The higher the family support, the higher the compliance” was accepted. (r＝.2604, p＜.01) Hypothesis II; “The higher the compliance, the higher the life satisfaction,” was rejected. (r＝.1663, p＞0.5) Hypothesis III; “The higher the family support, the higher the life satisfaction” was accepted. (r＝.3914, p＜.01) In addition, by using Stepwise Multiple Regression Analysis it was determined that the main influencing factors on the life satisfaction were family support, the number of inflammatory joints, compliance and pain level. These 4 main variables made it possible to explain 30.8% of the variance in life satisfaction. In conclusion, this study revealed that family support is an important factor that can improve compliance and life satisfaction in chronic arthritis patients.
