This Study was conducted to estimate the degree of dominance and gene frequency of some sueful characters in tobacco. The eight parents and a set of 28 crosses of F'1s was F'2s were used as materials, and planted on oriental's and burley cultivated system as randomized block designs, respectively. The observed characters were six agronomic characters which were plant height, number of leaves per plant, leaf length, leaf width, days to flowering and yield, and the data obtained from the experiment were analyzed from methods by Hayman's and Jinks. The results obtained are summarized as follows: 1. In Vr-Wr graphical analysis, number of leaves per plant, leaf length, days to flowering and yield were found to be inherited in partial dominance, and plant height was over dominance to be similar to complete dominance, but leaf width was inherited with partial dominance close to complete dominance. 2. In the gene frequency, two varieties Xanthi-Basma and KA 102, for days to flowering and yield had larger number of dominant genes as those were situated near the point of origen. 3. Additive effects of genes(D) were greater than dominance effects of Genes(H) for six agronomic characters except plant height, and mean degree of dominance over all loci was lower than 1 for days to flowering yield, leaf length and number of leaves per plant.

The purpose of this study was to identify the relationships between preschool teachers' hemispheric mode indicator and creative personality. The subjects were 205 preschool teachers from kindergarten or nursery school in Busan. The McCanthy(1993)'s HMI(Hemispheric Mode Indicator) and Torrance(1988)'s WKOPAY(What Kind Of Person Are You?) were used to examine the relationships preschool teachers' hemispheric mode indicator and creative personality. Results of this study as follows ; first, the hemispheric mode indicator of right hemispheric dominance were significantly positively correlated to the creative personality and inquisitiveness but negatively correlated to self-confidence among elements of creative personality. Second, the creative personality was significant difference according to hemispheric dominance types. That is, the creative personality of right hemispheric dominance was significantly higher than that of left or exhibit balanced hemispheric dominance but it was no difference between left hemispheric dominance and exhibit balanced hemispheric dominance. Third, there were significant difference self-confidence, inquisitiveness, and awareness of others but no difference Acceptance of Authority and Disciplined Imagination among elements of creative personality according to hemispheric dominance types.

When visual and auditory information is presented simultaneously, we perceive visual information dominantly over auditory information. This effect is called the visual dominance effect. This study was to examine the influence of semantic congruence of visual and auditory information on the visual dominance effect. The semantic congruence of visual and auditory information was manipulated. The results showed that the visual dominance effect obtained in error rates was not modulated by semantic congruence, whereas the effect in RT was. It is suggested that this modulation of the influence of semantic congruence on the visual dominance effect would be due to the task type.

Primary succession on bare rocks is a challenge for invaders, including one of which was plants. The invasion of bare rock by exotic species raises the question of whether their presence hinders or facilitates succession. This study aimed to determine the role of exotic species in primary succession in six overburden (OB) coal mines using a chronosequence approach. Vegetation analysis was undertaken using line transects. Measurements were carried out on the absolute and relative coverage of each species. Native and exotic species were identified and grouped using information from local communities, identification books, and websites. The relationship between time and number of species, time, and relative dominance of exotic and native species was analyzed using Pearson's correlation. Species number and dominance data were analyzed descriptively. The number of native species from the six OB heaps was higher (57) than that from exotic heaps (50). Neither the number of species nor the coverage showed a significant relationship with time. Exotic species predominated throughout the age of the embankment but tended to decrease over time. Temporary dominance by exotic species plays a role in assisting primary succession in the OB. This process might be prolonged without the temporary dominance of exotic species during early primary succession.

In the present study, hybrid vigour in terms of heterosis and over dominance of newly evolved bivoltine hybrids and their reciprocals raised from the promising newly evolved bivoltine breeds were calculated for the important parameters like pupation, cocoon yield, cocoon weight, shell weight, shell ratio, raw silk percentage, filament length and neatness. Through there was no significant difference among the hybrids for the characters pupation, cocoon yield and cocoon weight, the magnitude of heterosis and over dominance were varied significantly for these characters. However, significant differences were observed between new hybrids and control hybrid for the characters like cocoon shell weight, cocoon shell ratio, filament length and raw silk percentage. The results indicate that majority of new hybrids have shown higher heterosis and over dominance than control hybrid. The data also indicate that highest mean heterosis of all new hybrids was recorded for cocoon yield followed by filament length. Whereas highest mean over dominance was recorded for cocoon yield followed by cocoon weight. Negative mean heterosis and over dominance were recorded for the trait cocoon shell ratio. Based on the results, the importance of three hybrids viz., CSR2 ${\times}$ CSR4, CSR2 ${\times}$ CSR5 and CSR3 ${\times}$ CSR6 and their reciprocals (CSR4 ${\times}$ CSR2, CSR5 ${\times}$ CSR2 and CSR6 ${\times}$ CSR3) which exhibited significant heterosis and over dominance, for commercial exploitation was discussed.

The purpose of the study was to examine any difference in academic achievement, self-concept and achievement motivation by the types of hemispheric dominance. 189 high school students participated in the study. They were taken three kinds of different psychological tests i.e., the brain hemispheric preference (dominance), the self-concept and the achievement motivation tests. Three types of hemispheric dominance were classified as the left hemispheric, the right hemispheric and whole brain dominances. The results showed that students with the right hemispheric dominance showed lower academic achievement and self concept than the other groups students. Those who had left hemisphere dominance showed higher achievement motivation than the right hemispheric students. These results could be interpreted that education in the high school in Korea mainly focuses left hemisphere related topics or subjects.

Followingthe Four Rivers Project, cyanobacterial blooms have been frequently observed in the upstream of the installed weirs. The aim of this study was to characterize the major environmental factors that are associated with the cyanobacteria dominance in Baekje Weir (Geum River) and Juksan Weir (Youngsan River) based on intensive experiments and systematic data mining methods. The factors related to the cyanobacteria dominance include7-days cumulative rainfall (APRCP7), 7-days averaged flow (Q7day), water temperature (Temp), stratification strength (${\Delta}T$), electronic conductivity (EC), DO, pH, $NO_3-N$, $NH_3-N$, TN, TP, $PO_4-P$, Chl-a, Fe, BOD, COD, TOC, and $SiO_2$. The most highly correlatedfactors to the dominant cyanobacteria were found to be EC, Temp, Q7day, $PO_4-P$ in theBaekje Weir. On the other hand, those dominant in the Juksan Weir were ${\Delta}T$, TOC, Temp, EC and TN. The EC showed a strong correlation with cyanobacteria dominance in both weirs because a high EC represents a persisted low flow condition. The cyanobacteria dominance was as high as 56 % when the EC was equal or greater than $418{\mu}S/cm$ in Baekje Weir. It was as high as 63% when the ${\Delta}T{\geq}2.1^{\circ}C$ in the Juksan Weir. However, nutrients showed a minor correlation with cyanobacteria dominance in both weirs. The results suggest that the cyanobacteria dominate in astate where the water flow rate is low, water temperature is high and thermal stratification is strengthened. Therefore, the improvement of flow regimes is the most important to prevent persistent thermal stratification and formation of cyanobacteria bloom in theBaekje and JuksanWeirs.

This study investigates the dominant degree of product design factors through the process of change of design factors. The previous research suggested a concrete measurement method of dominant designs, but it did not investigate empirically the degree of dominance due to the limited data for changes of designs. In this research, thus, after collecting design data of mobile phones and we measured the dominance and structure change of the designs by year. The analyses showed the following two things. First, in design factors of mobile phone the dominance on the body form and the edge grows more and both of them as dominant design factors tend to converge into the rectangular body form and the round edge, respectively. Second, the dominance on other design factors(e.g. the button type, the open type, whether or not to have digital multimedia broadcasting(DMB) and video telephony functions, the combination of colors and the body color) increases and decreases; and hence, design levels tend to diverge. In conclusion, the measurement of dominance on product design factors contributes to marketing managers and designers who are required to establish a strategy for products under the rapidly changing circumstances of market. This research aims to provide those managers and designers with a guide line for a successful development of new product to prepare for the dominant design from this empirical study.
