  • Objective: The aim of the study was to evaluate genetic correlations between the behavioural profile and performance in laying hens as an indirect answer to the question whether the observed behavioural responses are associated with increased levels of stress in these birds. Methods: The assessment of birds' temperament was carried out using the novel objects test. The behavioural test was conducted in two successive generations comprising 9,483 Rhode Island White (RIW) birds (approx. 4,700 individuals per generation) and 4,326 Rhode Island Red (RIR) birds (approx. 2,100 individuals per generation). Based on the recorded responses, the birds were divided into two groups: a fearful profile (1,418 RIW hens and 580 RIR hens) and a brave/curious profile (8,065 RIW hens and 3,746 RIR hens). The birds were subjected to standard assessment of their performance traits, including SM, age at sexual maturity; ST, shell thickness; SG, egg specific gravity; EW, mean egg weight; IP, initial egg production; and HC, number of hatched chicks. The pedigree was three generations deep (including two behaviourrecorded generations). Estimation of the (co)variance components was performed with the Gibbs sampling method, which accounts for the discrete character of the behavioural profile denotation. Results: The analyses revealed negative correlations between the performance traits of the laying hens and the behavioural profile defined as fearful. In the group of fearful RIW birds, delayed sexual maturation (0.22) as well as a decrease in the initial egg production (-0.30), egg weight (-0.54), egg specific gravity (-0.331), shell thickness (-0.11), and the number of hatched chicks (-0.24) could be expected. These correlations were less pronounced in the RIR breed, in which the fearful birds exhibited a decline in hatchability (-0.37), egg specific gravity (-0.11), and the number of hatched chicks (-0.18). There were no correlations in the case of the other traits or they were positive but exhibited a substantial standard error, as for the egg weight. Conclusion: To sum up the results obtained, it can be noted that behavioural responses indicating fearfulness, i.e. escape, avoidance, and approach-avoidance may reflect negative emotions experienced by birds. The negative correlations with performance in the group of fearful hens may indirectly indicate a high level of stress in these birds, especially in the white-feathered birds, where stronger performance-fearfulness correlations were found. Fearful birds should be eliminated from breeding by inclusion of the behavioural profile in the selection criterion in the case of laying hens.

  • Persimmon (Diospyros kaki Thunb) fruit is one of the most important fruit and have been cultivated from ancient times in Korea. In this study, we found 16 EST-SSR markers that contained one or more EST-SSR sites from 246 cDNA sequences. The developing of EST-SSR marker analysis from 42 persimmon cultivars was compared by genetic relationships and morphological relationships using 6 qualitative traits (fruit related 6 traits) and 19 quantitative traits (flower related 19 traits). In this study, 25 primer sets were tested to identify PCR polymorphism and 14 potential EST-SSR primer pairs were selected. The result of morphological relationship EST-SSR marker analysis showed that the coefficient 0.02 was difficult to categorize in several groups. And then, coefficient 0.77 of genetic relationship showed that the group was classified as four groups. The result of correlation distance between genetic relationship and morphological relationship were investigated was low significance (-0.03). Our results also provided an optimized method for improvement of breeding efficiency and introduce of superior character at persimmon cultivars using EST-SSR markers which was useful for further investigation.

  • The purpose of this study is to examine high school students' perception of male home economics teachers and identify diverse viewpoints. To this end, the Q method was used, which is useful for operant subjectivity studies in which research participants create their own opinions and viewpoints. Based on the general procedures of the Q method, this study finalized 40 statements comprised of the representational system of high school students on male home economics teachers, which are Q samples, from the Q population. The statements were Q-sorted by P samples comprised of 31 high school seniors and analyzed using the QUANL program. The results showed that there were 4 different viewpoints of high school students on male home economics teachers. The type 1 focused on individual traits, claiming that the 'male' gender of home economics teachers and the 'home economics' subject are merely individual traits of the teachers. The type 2 focused on the subject, perceiving male home economics teachers with focus on the subject of home economics. The type 3 focused on competencies, thinking that male home economics teachers have sufficient skills and competencies to teach home economics. Finally, the type 4 focused on character, valuing the character of the teachers and thinking that male home economics teachers are great teachers who took up the challenge of teaching home economics. This study has significance as it provides the basic data for in-depth understanding of students' perception of male home economics teachers in individual context.

  • This study analyzes the characteristics, implications, and problems of Social Network of Press Organizations from the Kim Dae-jung administration to the Lee Myung-bak administration in Korea. For analyzing these issues, this study attempts to investigate the traits of social network structure based on the density analysis, distribution character analysis and correspondence analysis in each and among regimes. To answer these questions, this study utilizes human relationship data which related to personal network aspects (place of birth, affiliated college) and expertise aspects (types of major field), and which data has been gathered from the biographical web-site of Press Organizations in Korea. The results showed that the membership format of each Press Organizations depends on the connection with political environment directly and indirectly. Especially, the network traits of Broadcasting Press Organizations stands out a place of birth aspect. This findings indicate that the broadcasting policy reality that the path of decision making is connected with the political environment is more effective.

  • Objectives: The purpose of this study is to study the personality traits and cognitive characteristics of the Sasang constitution by comparing the Personality Test and Neuropsychological Test. Methods: A total of 121 subjects were analyzed with the results of a Two Step Questionnaire for the Sasang Constitution Diagnosis (TS-QSCD). Among them, the Personality Tests (SPQ, EPQ, TCI) and the Neuropsychological Tests (A-VLT, CPM, Stroop-CWIT, WCST) were processed and analyzed for Soyangin, Taeeumin, Soeumin. Results: 1. In the results of the SPQ, the Soyangin showed a significantly higher score than did the Taeeumin and Soeumin in Behavior, Emotionality, Cognition, as well as the Total Score. The SPQ-C score and SPQ-T were significantly higher for Soyangin, Soeumin and Taeeumin, in that order. 2. In the results of the EPQ, the Soyangin showed a significantly higher score than did the Taeeumin and Soeumin in Extraversion - introversion. Soeumin showed a significantly higher score than did the Soyangin and Taeeumin in Neuroticism. Soyangin also showed a significantly higher score than Taeeumin in Venturesomeness. 3. For the results of the TCI, the Soyangin showed a significantly lower score than did Taeeumin and Soeumin in Harm-Avoidance, but a significantly higher score in Persistence and Self-Directedness. Soyangin and Taeeumin showed a significantly higher score than did Soeumin for the total score of Self-Directedness+Cooperativeness. 4. The results of the Computerized Neuropsychological Tests (A-VLT, CPM, Stroop-CWIT, WCST) showed no significant differences between the Sasang constitution. Conclusions: The EPQ, TCI score showed significant differences between the Sasang constitution. But the Computerized Neuropsychological Tests developed to evaluate cognitive abilities did not show differences between the constitutional individuals and showed limitations as a research tool. Further studies are needed to devise a research method for ascertaining the cognitive behavioral characteristics of the Sasang constitution.

  • Because of the underground existence of roots, a few studies have been reported on root system. The developmental information of roots should be understood for the studies of specific tree traits and the influence of such traits on the soil surface fixation. In order to clarify the specific character of pine forest in Kangwon Province, the investigation on the form and distribution of root system of pine trees were carried out for 5 trees in the Campus Forest, Kangwon National Univ.. Root form was very well in flat root. As soil depth was approximatly 50cm, fine roots were very sparsly distributed(+), roots of 0.2cm in diameter were most common and roots > 0.2cm were very rare, also thickness thined. 60~70% all the roots were developed at the depth of 0~30cm, where big roots were below 0.9cm in diameter and fine roots were higly sparse(+).

  • In the postmodern world, it is widely believed that being a fool or looking foolish can be more profound and unique than being smart and serious. Comic characters, or fool characters in comedy, have been used as basic tools to make people laugh in various cultures around the world. As such, this study will summarize the types of fool characters that have been depicted in plays and organize how they can be categorized in a culture of laughter as well as revealing their characteristics in performing arts. The ridiculous actions and words of fool characters fall outside the common dichotomy of wisdom and foolishness. This is significant and it is because the ways in which they act overturn the values that we consider to be truthful in the world of experience and contain wit and ridicule beyond the general knowledge. Also, it's worth pointing out that many comic characters that appear on TV shows are not all the same. To put it simply, each and every funny character has unique traits and these characters predictably change according to the times. In performing arts, a fool character's personality is displayed through his or her interactions with the audience. That is, on one hand, the character may or may not recognize himself as a fool, while on the other hand, the audience may regard the character as a fool or otherwise. Based on this background, the comic characters that appear in performing arts are categorized into four types and their features are discussed.

  • Fourty lines of F4 progenies of an Adzuki bean cross, Jukdoo (Korean local variety) X Nesumimochi (Japanese variety) were used as the material, and these lines were grown in replicated trials in 1967. Phenotypic, genotypic and environmental covariances among all possible traits of eight character are calculated as shown in table 1. Phenotypic, genotypic and environmental correlations among all possible paris of eight characters were calculated as shown in table 2. In general, genotypic correlations were higher than the corresponding phenotypic corresponding phenotypic correlations. The genotypic correlations between seed yield (grain weight per plot) and oter agronomic characters indicated that seed yield was genetically associated with the character of pod number per plant, and grain number per plant, which is closely correlated with pod number pr plant, are affected more in Adzukl bean yield than the other agronomic characteracters.

  • Objectives : The purpose of this study was to validate the Sasang Personality Questionnaire (SPQ), based on the diagnosis of Sasang constitutional medicine clinical specialist. Methods : We performed Sasang type differentiation of 103 college students by certified specialist, and analyzed biopsychological traits of each groups with SPQ, Temperament and Character Inventory (TCI), Positive and Negative Affection Schedule (PANAS) and Body Mass Index (BMI). Results : The SPQ score of So-Yang ($33.1{\pm}0.79$), Tae-Eum ($29.03{\pm}0.67$) and So-Eum ($25.76{\pm}0.98$) Sasang groups showed significant differences from each other. The SPQ showed significant correlation with TCI Novelty-Seeking (r=.346), TCI Harm-Avoidance (r=-.348) and TCI Persistence (r=.346). But the BMI and PANAS did not show significant correlation with SPQ, although the PANAS Positive Affection (r=.332) has significant correlation with SPQ-Behavior. Conclusions : We confirmed the clinical validity of SPQ with clinical specialist and established biopsychosocial instruments. This study would contribute to a more objective diagnosis and studies on biopsychosocial mechanism of Sasang constitutional medicine.

  • A study is presented that examines the effect of personality on preference and purchase intention of positive and negative novelty design products. Participants evaluated their preference and purchase intention on 18 design products including positive and negative novelty design products. A cute Scream character was created as a positive novelty design and a skeleton Mickey character was used as a negative one. We measured extroversion, neuroticism, and visual product aesthetics as individual traits. The results shows that people, of course, prefer(and want to buy) the positive novelty design product to the negative novelty design product. Only in the case of the negative novelty design product, the more neurotic people is, the more they prefer it. Also, among the people who like the negative novelty design product, introvert ones are likely to purchase it but extroverted ones are not. These findings imply that personality plays an important role in liking and purchasing negative novelty design product.
