This study investigates how entrepreneurial competencies affect firm outcomes for necessity entrepreneurship in Korea. Based on a survey collected from 162 necessity entrepreneurs, this study conducted multiple regression analysis. The statistical results show that founder entrepreneurial competencies, such as risk-taking, tend to be associated with positive outcomes financially as well as non-financially, which suggests that the existing propositions of previous research on the relationship between risk-taking and firm performance can be applied to necessity entrepreneurship as well. Additionally, founder opportunity competencies and resilience increase the likelihood of better financial performance in necessity entrepreneurship compared to others, whereas their effect on non-financial performance is not statistically significant. This indicates that necessity entrepreneurs are likely to focus more on financial performance to survive than on non-financial performance, particularly concerning variables related to sustainability such as the environment and society. The findings of this study contribute to knowledge concerning the role of necessity entrepreneurs' competencies in the performance of their companies.

Allozyme studies have been widely used to estimate genetic variation and to describe genetic structure in natural populations. In many cases, the genetic diversity of recently established populations is generally lower than that of central populations. In addition, the genetic composition of an invasive species is influenced by its History of introduction as well as its ecological characters. Ageratina altissima (L.) R. King & H. Robinson (white snakeroot) is a perennial herb native to the eastern United States and Canada, and is currently receiving much attention for its rapid invasion of the Korean forests. Starch gel electrophoresis was used to assess the genetic variability at 11 putative loci in seven introduced populations of A. altissima in Seoul. Populations of A. altissima maintained lower levels of allozyme diversity (expected heterozygosity = 0.063) than those reported for other taxa with similar ecological traits. The degree of differentiation observed among A. altissima populations was considerably low. It is suggested that the populations were recently established from only a few founders via dispersal by human activities, resulting in the loss of genetic variation.

Transgenic chickens have been spotlighted as an highly potent bioreactor for their fecundity, short generation time, and eggs associated with mass production of protein. In this study, we generated transgenic chickens exhibiting oviduct specific expression of human growth hormone fused to human transferrin for oral administration. Gene of the modified growth hormone located at downstream ovalbumin promoter (~3.6 kb) was introduced to stage X blastodermal cell employing retrovirus vector system. Several transgenic chickens were successfully generated. However, genomic analyses showed unexpected deletion within the transgene. The modification of the transgene seemed to occur during germ cell formation because the deletion was detected only from the sperm DNA of the G0 founder animal. There was no evidence of deletion in the somatic cell DNA samples of the same chicken. Consequently, same pattern of the deletion was confirmed in both somatic and germ cells of the G1 progeny.

Transgenic rabbits were produced by DNA microinjection using growth hormone receptor (GHR) and IGF-1 receptor (IGF-1R) genes fused to metallothionein(MT) promoter. The overall efficiencies for production of transgenic rabbits were 3.2% and 3.1% for GHR and IGF-lR genes, respectively. Founder rabbits transmitted transgenes to their progenies through medelian fashion. Growth rate of GHR and IGF-lR transgenic rabbits was significantly faster than that of non-transgenic rabbits. Transgenic rabbits grew large. (25% and 15% increase in body weight of GHR and IGF-lR transgenic rabbits, respectively) than non-transgenic rabbits and organ weight of transgenic rabbits increased, suggesting that GHR and IGF-1R genes affects growth rates in transgenic rabbits.

Transgenic mice containing GH Receptor (GHR) gene fused to metallothionein promoter were analyzed to evaluate effect of GHR expression on growth in vivo. Three founder mice lines contained copies of GHR transgene and transmitted these genes into F$_1$ and F$_2$ progenies. The mRNA expression of transgene was identified using RT-PCR with GHR genes in tissues. To analyze the effects of transgenes on growth performance, body weights of pups were measured at 4, 10 and 14 weeks after birth. The body weight of transgenic mice was higher compared with that of non-transgenic control mice regardless of sex (P<0.05). Body weights between transgenic and non-transgenic mice were increased with aging. Overall, GHR transgenic mice tended to grow about 10 to 15 ％ faster than non-transgenic mice without any pathological defects.

Hans Freudenthal made important contributions to algebraic topology and geometry. He also made significant contributions in history of mathematics and mathematics education. In the 1970s, his intervention prevented the Netherlands from the movement of "new math". He had a very important role as a founder of realistic mathematics education and became famous internationally by that. Because he raised the profile of ICMI strongly, Bass used the expression 'Freudenthal Era' for the period that Freudenthal was the president of ICMI. Now many mathematics educator agree to use the Freudenthal Era when they mention about the history of ICMI. In this paper, we present on the life of Freudenthal and his contributions for mathematics education, especially ICMI.

With an emphasis on scientific literary, science education has again became closer to the interests and needs of people and sometimes expands its scope beyond the boundaries of school and the curriculum. Science educators often claim that its historical roots can be traced back to the movements of General Science and Science and Citizenship during the 1920s-40s. This study attempts to re-interpret the historical meanings of the Mechanics' Institute Movement (MIM) from the perspectives of science education. In doing so, this study first introduces the process of the emergence of MIM with a focus on its founder, George Birkbeck, and the Andersonian Institute where evening science classes began to be open to skilled workers. Then the overview of MIM is described, with examples drawn from the London Mechanics' Institute and the Manchester Mechanics' Institute. In discussing science teaching of MIM, the details taken from various mechanics' institutions are examined in terms of why, what, and how to teach sciences. This study argues that the MIM was a unique social phenomenon in which science could respond to the needs of skilled workers through education, providing science learning opportunities which were otherwise unavailable and that the MIM shared many similarities with current practice of science education, moving towards a wider career perspectives, cross-subject, community-based, and informed citizenship.

Purpose: This study was to present education and holistic care of Elizabeth J. Shepping (1880~1934), a nursing missionary and a founder of the Chosun Nursing Association who visited Korea during the Japanese colonial period. Methods: Primary and secondary sources were collected and analyzed. Results: This study provides important implications regarding Shepping's holistic nursing as follows: First, she came to Korea after studying nursing and bibliology and being trained for nursing missionary works. Second, she cared for many Koreans, especially Korean women, to protect them from poverty, oppression, ignorance, and illnesses. Third, she continued to spread holistic care in hospitals and other local communities. She trained nurses, developed nursing education, and produced a large number of domestic nursing leaders by establishing women's Bible school. Fourth, she founded the Chosun Nursing Association, serving as its first president for 10 years and applied to join the International Council of Nurses (ICN). Conclusion: Finally, suggestions were provided for future research, and it will be necessary to study thoroughly nursing achievements by nurses from other countries who practiced their nursing activities in Korea, and such studies are expected to lead to analysis of nursing missionaries' experiences.
