Research on entrepreneurial giftedness is in its initial stage and the importance is increasing these days. The purpose of this article is to establish a foundation of entrepreneurial giftedness research by conceptualizing the concept and characteristics of entrepreneurial giftedness. The author reviewed prior research on entrepreneur and entrepreneurship, potential entrepreneur, gifted youth in invention, and entrepreneurial gifted youth, and proposed a new perspective on entrepreneurial gifted youth based on the findings from the review. Entrepreneurial giftedness proposed in this study is someone who is risk-taking to achieve opportunities and innovation and who has potential to be competent in managing resources. The author also proposed that entrepreneurial giftedness study needs to focus on developmental characteristics, management ability, and practical intelligence. Finally, based on the findings from previous research on entrepreneurial giftedness, environmental and personality characteristics, temperament and character, cognitive traits, and vocational interest of entrepreneurial giftedness are discussed. Implications and further research directions were discussed.

Fusarium and Rhizoctonia genera are important pathogens of many field crops worldwide. They are constantly evolving and expanding their host range. Selecting resistant cultivars is an effective strategy to break their infection cycles. To this end, we screened a collection of Medicago truncatula accessions against Fusarium oxysporum, Fusarium solani, and Rhizoctonia solani strains isolated from different plant species. Despite the small collection, a biodiversity in the disease response of M. truncatula accessions ranging from resistant phenotypes to highly susceptible ones was observed. A17 showed relative resistance to all fungal strains with the lowest disease incidence and ratings while TN1.11 was among the susceptible accessions. As an initiation of the characterization of resistance mechanisms, the antioxidant enzymes' activities, at the early stages of infections, were compared between these contrasting accessions. Our results showed an increment of the antioxidant activities within A17 plants in leaves and roots. We also analyzed the responses of a population of recombinant inbred lines derived from the crossing of A17 and TN1.11 to the infection with the same fungal strains. The broad-sense heritability of measured traits ranged from 0.87 to 0.95, from 0.72 to 0.96, and from 0.14 to 0.85 under control, F. oxysporum, and R. solani conditions, respectively. This high estimated heritability underlines the importance of further molecular analysis of the observed resistance to identify selection markers that could be incorporated into a breeding program and thus improving soil-borne pathogens resistance in crops.

The effect of modifiers on the optical features and radiation defying ability of the Eu³⁺ ions doped multi constituent glasses was examined. XRD has established the amorphous nature of the specimen. The presence of various functional/fundamental groups in the present glasses was analyzed through FTIR spectra. The physical, structural and elastic traits of the glasses were explored. The variation in the structural compactness of the glass structure according to the incorporated modifier was enlightened to describe their suitability for a better shielding media. For the examined glasses, the metallization criterion value varied in the range 0.613-0.692, indicating the non-metallic character of the glasses with possible nonlinear optical applications. The computed elastic moduli expose the Li-containing glass (BTLi:Eu) to be tightly packed and rigid, which is a requirement for a better shielding channel. Furthermore, the optical bandgap and the Urbach energy values are calculated based on the optical absorption spectra. The evaluated bonding parameters revealed the nature of the fabricated glasses covalent. In addition, we investigated the radiation attenuation attributes of the prepared Eu³⁺ ions doped multi constituent glasses using Phy-X software. We determined the linear attenuation coefficient (LAC) and reported the influence of the five oxides Li₂O₃, CaO, BaO, SrO, and ZnO on the LAC values. The LAC varied between 0.433 and 0.549 cm^-1 at 0.284 MeV. The 39B₂O₃-25TeO₂-15Li₂O₃-10Na₂O-10K₂O-1Eu₂O₃ glass has a much smaller LAC than the other glasses.

The objective of the article is to describe the social structure of Uruguay at the beginning of the sixties, presenting the social differences that configured the level of urban centers or localities since the beginning of the 20th century. The willing is to identify what historical processes would have intervened to have institutionalized a highly heterogeneous distribution of welfare in the territory. The sources of information are four: (i) the population censuses of 1908 and 1963; (ii) the agricultural censuses of 1908, 1951, 1956 and 1961; (iii) the work of historical demography; and (iv) the indices published by the General Directorate of Statistics and Censuses in 1971 and 1989. Due to the lack of a dictionary of the localities, the authors matched these sources. The regional configuration processes analyzed here are: the departmentalization of the territory; the agriculturization; the industrialization and the balnearización. In each case, the regional and local impact of the political, economic and social transformation is analyzed. The article dedicate a wide space to describe the changes in the entity, the legal status, the territorial distribution and the wellbeing of the localities, marking especially those under 1500 inhabitants, which make up an important micro-urbanization of the country. The foundation of 70% of the localities occurred during the reformist period that locates that project as a type of "social democratic" State with its "Bismarkian" type traits. The institutionalization of these territories is based on their precarious and very poor character, the inequality in the most elementary welfare enjoyed by the established towns and cities increases. The processes of spatialization that reconfigured the territory during this time, contributed to the urbanization and population relocation, but in a framework in the political project of the "small model country" did not plan on the territory, the state have no special attention to correct the asymmetries in local welfare distribution structures. We finished with the hypothesis that beyond the social advances of the "Battlista" period, the territorial inequality of opportunities has grown between 1908 and 1963 because the lack of a public planification.

This study aims to answer the research question of what are the global leadership competencies(GLC) and what is the integrating framework of GLC? To attain the goal of reframing the GLC models with systematic research on GLC, the specific objectives are delineated as follows; the first objective is to identify the area of GLC. The second one is to extract the dimensions agreed with consensus. The third one is to suggest the reframed GLC model. Through the literature review and content analysis about GLC and global mindset, the two dimensions-subject and objects-of GLC model are emerged to classify the existing clusters of GLC. The extracted objects are self, others, culture, business, and global world. The dimension of subject who is global leader is more specifically divided into the knowing/doing process and three aspects of human activity like cognitive, emotional, and behavioral one. GLC are reframed and rearranged based on the two dimensions. As a results new framework for GLC with 11 clusters are presented. Knowing group of GLC contains personal, social, cultural, business literacy, and global mindset. Doing group of GLC contains personal, social, cultural, business savvy, and global change. Personal traits as a core character are at the core of the knowing and doing process of the self. Lastly, the implications and limitations of this research are suggested, and suggestion for further research is followed.

The narratives of the digital age have attempted interactions, and the interactive storytelling represented by the Branch Narratives has a problem of the expensive production cost of many optional implementations and poor narrative compared to linear story. As an alternative to this, this study proposes a user-oriented storytelling using user's personality traits. Using the Enneagram, a model of human psyche, and the Actantial model of the semiotician Greimas, when stories and characters are the same, the story could be reconstructed by deriving different topics from the same story according to the user's Enneagram personality type. The theme is determined by defining the axis of the desire of the Actantial model by respectively setting the character with the user's Enneagram type as the subject and the core value in the type as the object. The axis of Power could be defined by the stress and security points in Enneagram. In this way, we can derive the themes of 9 Enneagram types and the corresponding Actantial model and make plots. The users will appreciate one of these reconstructed plots in different perspectives and themes, depending on their personality type. In this study, we applied the above methodology to the story of the pansori novel "Tokkijeon". User-centered storytelling is a new attempt to predict user's choice and reconstruct the story based on the user's personality and perspective.

The historic cultural landscape of East lake in Kyung river area during Joseon dynasty was very outstanding that it had many attractions of scenic beauty, however, the Han river of today is being recognized as a natural landscape and as a place with low cultural and historical traits. This study applied landscape characteristics of the cultural space of Joseon Dynasty on visual image elements of Lynch to research the landscape characteristics. The research results are as follows. When East lake was applied to visual image elements, it was recognized as a 'superb' 'paths,' and the 'edge' which signifies the boundary showed its 'superb' clarity of the East lake. For the 'node,' a turning point of direction, Dumopo represented the 'superb' awareness. As East lake, Apgujung, and Jecheonjung represented the 'superb' awareness when 'landmark' among visual image elements of Lynch was applied to the cultural space, the awareness level and reputation were proportional to the visual image elements. When pattern, structure, and meaning of the cultural space were clear and had definite identity, the 'landmark' and 'district' elements were 'superb.' It was also identified that when awareness level of space was higher, the awareness of historic cultural landscape was high as well. Therefore, considering visual awareness level of the historic cultural landscape of Han river during restoration to investigate and to conduct case studies is considered to increase the awareness level of historicity and cultural character as well as restoration of the place.

The experiment was carried out at the Yeongnam Crop Experiment Station in 1984 and 1990 to obtain the basic information on kneeing responses of rice cultivars and Echinochloa species. Kneeing response of rice cultivars was not directly related with cultivar group(Tongil-type vs Japonica-type), maturity, culm length, or other agronomic traits and thus concluded that kneeing ability was soly peculiar cultivar character based on its genetic background. Cultivars having relatively great kneeing ability were Yeongdeog 1(Japonica), Seogwangbyeo(Tongil-type). Somjinbyeo(Japonica), Pungsanbyeo(Tongil -type), Hangangchalbyeo(Tongil-type), etc. while these for low kneeing ability cultivars were Chilseoungbyeo, Gayabyeo, and Samgangbyeo that were all belonged to Tongil-types, respectively. Two Echinochloa species were not much differed from each other in kneeing ability. However, kneeing ability of Echinochloa species was much greater than rice cultivars. Kneeing ability of Echinochloa species was not differed by culm node order : all the visual nodes(5~6 nodes) exhibited similar kneeing ability having more or less 30${\circ}$ in each node.

The study was conducted to determine the inherited properties of the MEB resistance to natural population of the small brown plant-hopper(Laodelphax striatelluss). The plant-hoppers were collected from the natural population of Naju area where the highest insecticide resistance of MEF to the green rice leaf hopper (Nephotettix cincticeps) have been examined in 1976. And Naju collections were crossed to the susceptible Lab stock to examine the MEP resistance in the $F_1,\;BC_1F_1\;and\;F_2$ and $F_2$ populations. Ail the data were analyzed by the probit method. There was a difference in MEP resistance between Naju collection and susceptible Lab stock, showing $LD_{50}$ value of the former was 0.0029ug/insect compared to 0.0008ug/insect for the later. The $LD_{50}$ values and dosage-mortality lines of the $F_1$ and $BC_1F_1$ tended to close their resistant parent. and it was considered that the character of the MEP resistance in the Naju collection of the small brown plant hopper was controlled by the genetic traits. However, $LD_{50}$ value and dosasage-mortality lines of the $F_2$ populations were intermediate to their parents, it would be conclusive that the trait will be governed by a interaction of the genes or factors rather than the single genic control.

The purpose of this study is to investigate the problems and conditions of educational guidance and counselling of teachers in the gifted classes. For the study, 267 teachers were sampled from the Gifted Education Institutes of metropolitan and provincial offices of education and Gifted Classes of the school across Korea, and the questionnaire developed by the researchers were administered to them. The results of this study are as follows : First, the 82% of respondents reported that the guidance and counselling in the gifted education is needed. So it demands the active responsive strategies on it. Second, the respondents reported that the selfish or self-centered traits of the gifted students are the most problematic in the gifted classes. It shows the emphasis should be put on the basic life habits and moral education in the guidance and counselling of the gifted education. Third, they pointed out the case-based education is needed for the parents of the gifted to correct their misconceptions about their children. Fourth, to support the teachers of the gifted program, the administrative measures have to be taken, like operation of character education program, forming a consultative group with the experienced teachers, developing the case-based guideline for the guidance and counselling for the gifted education, etc. Fifth, we should develop the Korean model of the gifted education to promote social capital for our future society.
