  • The magnitude of additive effects generally parralled the magnitude of difference between parental means and appeared to be more independent from non - allelic interaction than dominance effects, whereas the magnitude of dominance effects were inflated by non-allelic interaction. Additive effects were significant for all characteristics observed and those of leaf width and leaf shape index of lugs, cutter and leaf and leaf width of tips were higher than dominance effects. Non-allelic gene interaction was expressed in leaf length of lugs, cutter and tips and heterosis of these characters were lower than the other characters.

  • The purpose of this study was to investigate the causal relationships of need, self-esteem, body satisfaction on aesthetic surgery attitude of female. The method of the study was survey research by using questionnaires. Subjects were 813 females of 10's to 40's living in Daejeon Metropolitan City and Gongju City, Chungchungnamdo. Statistical analysis methods were one-way ANOVA. Duncan's multiple range test, Pearson's correlation coefficient, and multiple regression analysis. The results of the study were as follows. Women with lower body satisfaction and self-esteem had a tendency to keep the secret of aesthetic surgery. Women in higher social class and having higher need for dominance showed also strong tendency to keep the secret of aesthetic surgery. Women with lower body satisfaction and having higher needs for achievement and exhibition appreciated the value of aesthetic surgery more. Women with lower body satisfaction and self-esteem but with higher need for exhibition and dominance were more willing to confirm the aesthetic surgery Women with higher need for dominance but with lower self-esteem and body satisfaction were more willing to undergo aesthetic surgery in spite of high cost of surgery. Women having lower self-esteem, lower need for achievement, and lower body satisfaction were more willing to admit the risk tolerance of aesthetic surgery. As a conclusion, need, self-esteem, and body satisfaction constituted important characteristics which could affect aesthetic surgery attitude directly. Women having higher need were more willing to admit the change of body shape via aesthetic surgery.

  • Why do some countries walk on the right and others on the left? People have a dominant hand which leads to a natural tendency to favor one side of the road or another depending on the means of transportation being used. The primary objective of this study was to investigate the stereotype of Korean regarding preferred walking direction in encountering various facilities and provide the appropriate information to traffic policy makers. Six hundred Korean male and female subjects aging from 12 to 83 were selected to investigate the various statistics about their preferred walking direction and their employment characteristics on walking diverse facilities. The walking directions of eleven different facilities were asked along with other relative subjects' characteristics(e.g., age, gender, hand and foot dominance) to determine the relationship among these obtained data. The descriptive statistics showed that 73.7% and 26.3% were preferred walking right and left direction respectively. Moreover, various statistical analysis revealed that general tendency of walking direction was varied by hand and foot dominances. There were strong tendency that right-handed people prefer walking right side of the road and vise versa, hence this should be considered in setting up traffic policies. As a concluding remark, it is better to design traffic policies and regulations in the way that peoples' preference and expectation.

  • In a situation that ordinal preferences on multiattribute weights are captured, we present two solution approaches: an exact approach and an approximate method. The former, an exact solution approach via interaction with a decision-maker, pursues the progressive reduction of a set of non-dominated alternatives by narrowing down the feasible attribute weights region. Subsequent interactive questions and responses, however, sometimes may not guarantee the best alternative or a complete rank order of a set of alternatives that the decision-maker desires to have. Approximate solution approaches, on the other hand, can be divided into three categories including surrogate weights methods, dominance value-based decision rules, and three classical decision rules. Their efficacies are evaluated in terms of choice accuracy via a simulation analysis. The simulation results indicate that a proposed hybrid approach, intended to combine an exact solution approach through interaction and a dominance value-based approach, is recommendable for aiding a decision making in a case that a final choice is seldom made at single step under attribute weights that are imprecisely specified beyond ordinal descriptions.

  • The young casual wear market has been recently increased by the great buying power of the target consumers, although they don't have their own discretionary income. The purpose of this study was to investigate clothing attitudes of the adolescent consumers of the young casual wear market according to the groups of personality types. The questions on introversion/extroversion of MBTI test were adopted to measure introversion/extroversion in personal characteristics. The questions in "The personality diagnosis of high school students" developed by Lee, Chongseung and Chung, Bummo were adopted to measure stability, dominance, sociability and autonomy. Variables of clothing attitudes were composed with attentiveness, modesty and conformity. A total 488 high school students in Seoul participated in the survey. SPSS Win 10 statistical package was used to analyze the data: frequency, t-test, ANOVA and factor analysis. After statistical analysis, the following results were found. Groups of introversion and extroversion, and groups of low, medium and high degree of stability, dominance, sociability and autonomy showed no significant difference based on sex difference and school types. Students who has a high extroversion showed a high degree of attentiveness in clothing attitudes. Students who has the lowest sociability and the lowest autonomy showed a high degree of attentiveness. Students with the lowest autonomy showed a high degree of conformity. The younger the students were, the higher their attentiveness and modesty in clothing attitudes.

  • This study was carried out to get the genetic information on the germination rate and fat acidity after 12 weeks' storage at $35^{\circ}C$. Germination rate decreased with longer storage period, while fat acidity increased. Germination rate was higher in the order of Koshihikari, Hanmaeum and Unkwangbyeo after 12 weeks' storage at $35^{\circ}C$. Fat acidity of Koshihikari and Hanmaeum was gradually increased, but that of Unkwangbyeo was dramatically increased after 4 weeks' storage at $35^{\circ}C$. The genetic mode on germination rate and fat acidity using the joint scaling test was shown to be additive-dominance gene effects. Additive([d]) effect was higher than dominance effect([h]) in all crosses. The average degree of dominance, [h]/[d], was less than 1, indicating that germination rate and fat acidity was partially dominant. Germination rate and fat acidity based on frequency distribution of 2 crosses were quantitative characters expressed by polygenes.

  • Han River estuary (HRE) is located at the middle of the western coast of Korea, and tidal currents were measured at 4 stations in this estuary during the winter season, and previously observed tide data was analyzed. The results of amplitude ratio of $M_4/M_2$ showed that increasing upward to estuary in the HRE. Tide harmonic constants of relative phase $2M_2-M_4$ represent flood dominance, with under 180 degree. But this method has a limit of analysis that typically based on the non-linear distortion of the tidal current in tidal lagoon system where freshwater discharge is assumed to be relatively small. The results of statistically tidal current data indicated that ebb current velocity would be great unlike tide data. Ebb and flood duration time is calculated by slack time of tidal current showed that ebb duration time is longer than flood. The results of correlation of analysis show high value (0.9) between tidal current stations from Incheon harbor to north entrance of Yeomha channel. We reconstructed to find the reasons for the features of ebb dominance the results of harmonic analysis. As major component ($M_2$) in combination with shallow water component ($M_4$), the tidal curve was presented flood dominance that has a flood current is stronger. However, these curve were changed to ebb dominance add up the non-harmonic components that had ebb direction flow by calculated tidally averaged current. The characteristic of enhancement on ebb is showed around the Yeomha channel in the HRE, because averaged flow which acts seaward such as long-term tidal current components due to non-linear effect and freshwater which overcome the flood current.

  • The purpose of this study was to identify the difference of creativity according to the type of brain dominance for deveoping pre-service early childhood teachers's creativity teacher education program. The subjects of this study were 210 pre-service early childhood teachers. The tests were conducted by using the Herrmann' BDI and TTCT: verbal. The study have applied Pearson product-moment correlation to find out relation between the type of brain dominance and creativity, and used multi-variate analysis to find out the difference of creativity according to the type of brain dominance. The results of the study are as follow; first, the upper left brain, lower left limb, and right brains had no relation to fluency, flexibility, originality and overall linguistic creativity. The lower right limb showed a positive correlation with fluency, flexibility, originality, and overall linguistic creativity. Second, the lower left, upper right lower, and lower right limb dominant teachers showed higher fluency, flexibility, originality and overall linguistic creativity than upper left neural dominant teachers. The result of analyzing the language creativity according to the type of brain dominance of the pre-service early childhood teachers will be used as a suggestion to develop the brain-based creativity teacher education program.

  • Objective : Determining language lateralization is important for the presurgical evaluation of patients with medically intractable epilepsy. The Wada test has been the gold standard for lateralization of language dominance before epilepsy surgery. However, it is an invasive test with risk, and have some limitations. Methods : We compared the volumetric analysis with Wada test, and studied the clinical potential of volumetric analysis to assess language laterality in large surgical candidates with temporal lobe epilepsy (TLE). To examine the efficacy of volumetric analysis to determine language lateralization during presurgical evaluation, we compared the volumetric analysis of the bilateral planum temporale with the results of Wada test in 59 patients with chronic intractable TLE (rTLE, n=32; lTLE, n=27) who underwent epilepsy surgery. We measured the gray matter volumes of planum temporale (PT) of each patients using the VoxelPlus2 program (Mevisys, Daejeon, Korea). Results : Overall congruence of the volumetric analysis with the Wada test was 97.75% in rTLE patients and 81.5% in lTLE patients. There were more significant leftward asymmetry of the PT in rTLE patients than lTLE patients. In lTLE patients, relatively high proportion (37%) of the patients showed bilateral or right hemispheric language dominance. Conclusion : These results provide evidence that the volumetric analysis of the PT could be used as an alternatives in language lateralization. Also, the results of the Wada test suggested that there was considerable plasticity of language representation in the brains of patients with intractable TLE and it was associated with an earlier age of brain injury.
