  • This paper attempts to find out the psychological characteristic factors of Korean consumers, and to identify how they influence consumers' attitudes toward the products for the world famous brands. The related literature refers face-consciousness trait, boast trait and ritualism trait to the main research objectives of this research. As results, 3 underlying factors are found to underly the 'Chemyon(social face)', 6 factors to 'Uzzul(Boasting)'. Multiple regression analysis reports that 'Uzzul(Boasting)' trait has a significant influence over the consumer's attitudes toward the product for the famous brands, and Chemyon(social face) trait has the same effects as well though with less statistical weight. The paper's findings suggests academically that we need more serious research endeavor to understand consumption propensities that are salient to Korean consumers. And, they also imply that advertising creative director would implement the knowledge in developing creative strategy for brand advertising.

  • Objective: The objective of the study was to investigate the possibility of utilizing an early litter size trait as an indirect selection trait for longevity and to estimate genetic parameters between sow stayability and litter size at different parities using a linear-threshold model for longevity in Thai Large White (LW) and Landrace (LR) populations. Methods: The data included litter size at first, second, and third parities (NBA1, NBA2, and NBA3) and sow stayability from first to fourth farrowings (STAY14). The data was obtained from 10,794 LR and 9,475 LW sows. Genetic parameters were estimated using the multiple-trait animal model. A linear-threshold model was used in which NBA1, NBA2, and NBA3 were continuous traits, while STAY14 was considered a binary trait. Results: Heritabilities for litter size were low and ranged from 0.01 to 0.06 for both LR and LW breeds. Similarly, heritabilities for stayability were low for both breeds. Genetic associations between litter size and stayability ranged from 0.43 to 0.65 for LR populations and 0.12 to 0.55 for LW populations. The genetic correlation between NBA1 and STAY14 was moderate and in a favorable direction for both LR and LW breeds (0.65 and 0.55, respectively). Conclusion: A linear-threshold model could be utilized to analyze litter size and sow stayability traits. Furthermore, selection for litter size at first parity, which was the genetic trait correlated with longevity, is possible when one attempts to improve lifetime productivity in Thai swine populations.

  • A direct and precise explanation of soybean resistance to soybean cyst nematode will be possible only when the individual gene(s) involved in the resistance are tagged. This study was conducted, (1) to identify and localize quantitative trait loci for resistance to soybean cyst nematode race 14 on RAPD map, (2) to identify the magnitude and mode of inheritance for each quantitative trait loci, and (3) to identify the best combinations of quantitative trait loci for resistance to soybean cyst nematode race 14. Thirty markers (29 RAPD and 1 RFLP) showed significant association with resistance to soybean cyst nematode race 14. From MAPMAKER/QTL analysis, we identified two regions (linkage group C-7 and linkage group C-9) for resistance to soybean cyst nematode .ace 14. The first quantitative trait loci that was localized at 6.0 cM from $H06^1$ on linkage group C-7 showed a dominant inheritance mode. However, we can not exclude the possibility of additive inheritance mode. The second quantitative trait loci that was localized between $B15^2$ and $E01^1$ on linkage group C-9 also showed a dominant mode of inheritance. One pair of flanking markers ($H06^1$ and $H06^2$) and B15$^2$ were used for multiple regression analysis. Marker combination that included 2 markers, $B15^2$ and $H06^1$, explained the highest total variance (22.9%) for resistance to soybean cyst nematode race 14. Further localization of genes for resistance to soybean cyst nematode race 14 and examination of interaction between quantitative trait loci will accelerate the exploitation of resistance to soybean cyst nematode.

  • Backgrounds : There has been many studies investigating the causes of farmers' syndrome. In some studies, psychologic stress is related to farmer's syndrome. And the diagnostic criteria of farmer's syndrome is similar to those of generalized anxiety disorder. So we carried out this study to investigate the psychiatric causes of farmers' syndrome. Methods : This study was done in some rural and urban areas of Kyoungsangnam Province, July, August, October and November of 1996. Those who came to free medical service and completed interview, medical examination and laboratory examination and 20-59 years old were 150 persons. And those who came to health center for health examination and completed only interview and 20-59 years old were 94 persons. The questionnaire was composed of sociodemographic factors, health risk factors, farmer's syndrome, work load, BEPSI(inventory to measure stress), Spielberger's state-trait anxiety inventory, self-rating depression scale. To examine statistical significance, we used X2-test, Mantel-Haenszel test for linear association, t-test, ANCOVA, correlation, multiple regression, logistic regression. Results : The prevalence of farmer's syndrome, adjusted for age and sex with population of Kyungsangnam Province of 1993 was 208 per 1,000(90 per 1,000 in men and 329 per 1,000 in women). In bivariate analysis, farmer's syndrome was significantly related to age, sex, job, income, smoking, alcohol drinking, work load, BEPSI, state anxiety, trait anxiety, depression, body mass index, Hwa-Byung, hypertension, anemia. However, when age and sex were adjusted, job was not significantly related to farmer's syndrome. The score of farmer's syndrome was significantly related to age, sex, work load, BEPSI, trait anxiety by multiple regression. Farmer's syndrome was significantly related to increasing age(odd ratio 1.079, 95% C.I. 1.060 - 1.099), sex(odds ratio of male 0.434, 95% C.I. 0.349 - 0.540), and BEPSI(odds ratio 1.231, 95% C.I. 1.148 - 1.320) by logistic regression. Results of logistic regression analysis of the component symptoms of farmer's syndrome were as follows. Shoulder stiffness was significantly related to increasing age, female sex and BEPSI. Lumbago was significantly related to increasing age, female sex and trait anxiety. Numb limbs and nocturia was significantly related to increasing age and female sex. Breathlessness was significantly related to work load, sleeplessness was significantly related to depression, dizziness was significantly related to job and state anxiety, and abdominal fullness was significantly related to female sex. Conclusion : Farmers' syndrome was related to work load, but was more related to psychiatric factors such as BEPSI and trait anxiety. And the occupation was not risk factor of farmers' syndrome in this study, so further study is needed to investigate the cause of farmers' syndrome.

  • The purpose of this study was to examine the stressors and coping strategies of school -age children and to explore the relationship between stressful life events and health symptoms and the effects of coping and trait anxiety which is theoretically considered to mediate the relationship between stress and health symptom. The study subjects consisted of 639 elementary school children in the fourth to sixth grade living in Seoul. Of the 639 subjects, 348 were boys and 291 were girls. The mean age was 11.35 (SD=.86). The Feel Bad Scale(FBS), Schoolager's Coping Strategy Inventory(SCSI), Spielberger's Trait Anxiety Scale for Children(STAIC), and Health Symptom Questionnaire (HSQ) were adapted for this study. A pilot study was undertaken to ascertain the reliability and validity of the instruments. The Cronbach alphas of FBS, SCSI, STAIC and HSQ were from .81 to .92. The Researcher and a research assistant visited the school and data were collected in the class using the questionnaire method after an explanation of the purpose and procedures was given to the children. Data collection was done during the period between Nov.25 to Dec.19, 1995. Using the SAS statistical program, percentages, t-test, ANOVA, correlation analysis, and multiple regression were used for data analysis. The result are as follows : 1. The mean score for the FBS was 204.79(range : 48-472) and there was a significant difference according to grade. The most severe stressors perceived by children were parental divorce and death or illness of family members. The most frequently experienced stressful life events were conflict with siblings and being home alone. 2. The mean score for the SCSI was 57.36(range : 9-118) and there was a significant difference according to grade. The most frequently used, and perceived as helpful, coping strategies were distraction and cognitive activities. 3. The mean score for the HSQ were 20.7(range : 0-81) and there were significant differences according to grade and sex. The percentage of the children answering that they perceived their health state as not good was 3.9%. 4. The mean score for the STAIC was 33.76 and there were significant differences according to grade and sex. 5. There was a significant relationship between stressful life events and health symptoms ( r=.53, p<.01). Also, Stressful life events were postively related with coping strategies(r=.39, p<.01). Trait anxiety was highly correlated with health symptoms(r=.72, p<.01). 6. To examine the multivariate effects of the variables to health symptoms, multiple regression was performed. Stressful life events, coping, trait anxiety, and health concerns were identified as significant variables. Explanation of the health symptoms by these variables was 56.78%. The study revealed that stressful life events correlated with health symptoms in school-age children and coping and trait anxiety had mediating effects on this relationship. The implication for nursing is that there is a need to develop supportive interventions for high risk population to decrease health problems due to stress. Also, it is recommended that a study be conducted to explore protective factors for the prevention of health problems in children.

  • Purpose: The purpose of this study was to identify the relationships among trait anger, anger expression, job satisfaction, job commitment, and organizational performance, and especially to verify the effect of anger experience on organizational performance. Method: A descriptive study was conducted using a convenient sample. Data were collected by a self-report questionnaire from 671 clinical nurses in three university hospitals and analyzed by using SPSS 14.0 Win program with descriptive statistics, t-test, ANOVA, pearson correlation coefficient, and stepwise multiple regression. Result: Organizational performance was significantly correlated with trait anger, anger expression-in, anger expression-out, anger control, job satisfaction, and job commitment. Multiple regression analysis showed that organizational performance was significantly predicted by job commitment, job satisfaction, educational level (university graduation), anger control, and working place (operative room), and 34.7% was explained by these variables. Conclusions: Out of anger expression, anger control significantly affected on organizational performance together with job commitment and job satisfaction. From this result, it could be concluded that nursing intervention for anger control have a positive effect on improving organizational performance. Further studies are needed to develop and test the effect of nursing intervention programs for anger control.

  • In this paper, simulation was used to determine accuracies of genomic breeding values for polygenic traits associated with many thousands of markers obtained from high density genome scans. The statistical approach was based upon stochastically simulating a pedigree with a specified base population and a specified set of population parameters including the effective and noneffective marker distances and generation time. For this population, marker and quantitative trait locus (QTL) genotypes were generated using either a single linkage group or multiple linkage group model. Single nucleotide polymorphism (SNP) was simulated for an entire bovine genome (except for the sex chromosome, n = 29) including linkage and recombination. Individuals drawn from the simulated population with specified marker and QTL genotypes were randomly mated to establish appropriate levels of linkage disequilibrium for ten generations. Phenotype and genomic SNP data sets were obtained from individuals starting after two generations. Genetic prediction was accomplished by statistically modeling the genomic relationship matrix and standard BLUP methods. The effect of the number of linkage groups was also investigated to determine its influence on the accuracy of breeding values for genomic selection. When using high density scan data (0.08 cM marker distance), accuracies of breeding values on juveniles were obtained of 0.60 and 0.82, for a low heritable trait (0.10) and high heritable trait (0.50), respectively, in the single linkage group model. Estimates of 0.38 and 0.60 were obtained for the same cases in the multiple linkage group models. Unexpectedly, use of BLUP regression methods across many chromosomes was found to give rise to reduced accuracy in breeding value determination. The reasons for this remain a target for further research, but the role of Mendelian sampling may play a fundamental role in producing this effect.

  • Purpose: This study was conducted in order to define factors influencing learned helplessness in undergraduates. Independent variables including external entrapment, internal entrapment, social support, trait anger, state anger, and anger expression were used to predict learned helplessness. Methods: Data were analyzed using the SPSS/WIN 20.0 program for descriptive statistics, Pearson correlation coefficients and stepwise multiple regression. A total of 241 undergraduates recruited from September to November 2012 were included in the study. Results: Four factors of learned helplessness were founded to show significant correlation with external entrapment, internal entrapment, social support, trait anger, state anger and anger expression. Stepwise multiple regression analysis showed that 64% of the variance in learned helplessness was significantly accounted for by internal entrapment, social support and anger expression. Conclusion: This study showed that perceived entrapment and social support are important predictors of learned helplessness. Therefore, in order to reduce learned helplessness in undergraduates, it is necessary to design an intervention program with strategies to help in coping with and reducing perceived entrapments.
