  • Transgenic mice were generated by microinjecting a plasmid DNA containing the SV40 (simian virus 40) large T antigen (Tag) gene fused with mouse albumin promoter/enhancer sequences into fertilized one-cell mouse embryos. Among eleven founder transgenic animals, four developed hepatocellular carcinoma, two showed kidney cancer and one developed skin and brain tumors. Three stable transgenic lines, #1-2, #1-6 and #1-11 were established. Members of the lines #1-6 and #1-11 reproducibly developed liver tumors by 8 to 10 weeks of age but did not exhibit any phenotypic changes in other tissues. Histological changes loading to liver tumor formation occurred with predictable kinetics and could be classified into three distinct stages; (a) newborn to 3 weeks of age, characterized by hyperplastic hepatocytes with reduced amounts of cytoplasm without any nuclear alterations, (b) between 4 to 8 weeks of age, characterized by diffuse liver cell dysplasia without observable tumor nodules, and (c) 9 weeks of age and thereafter, characterized by hepatocellular carcinomas in the background of extensive liver dysplasia. Metastasis to the lung from a liver carcinoma was observed in #1-11 founder animal. This transgenic mouse system displays similarities with human liver cancers in a number of aspects and provides a useful model for the study of molecular events involved in hepatocarcinogenesis.

  • Purpose - Entrepreneurship promotion is emerging as an important economic growth agenda. However, in Korea, entrepreneurship has weakened because of the collapse of the venture bubbles of the 2000s and the global economic recession in 2008, which have induced the business community to choose stability over risk. The Korean government has been implementing several support projects to inspire and promote youth entrepreneurship through various means including financial assistance; however, the perpetuation rate of young entrepreneurship is still low as compared to advanced economies such as the US and EU. This case study focuses on the Youth Start-Up Business Support Program of the Small & Medium Business Corporation, and explores practical alternatives. Further, it aims to suggest managerial factors and a conceptual model for change management factors affecting the business performance creation of a startup company, based on the Small and medium Business Corporation's young venture startup fund. Research design, data, and methodology - Many studies examine the current progress and issues of startup firms, for example, a lack of systematic cultivation of entrepreneurship and startup business training, lack of commercialization funding for youth startup businesses, lack of mentoring, and inadequate infrastructure. From prior research, we address four factors, namely, personal managerial capabilities, innovative business model, sufficient cash flow, and social network, affecting startup companies' business performance. This study involved a sample survey of 200 young entrepreneurs to investigate casual relations between the four factors and business performance. A regression analysis was used to verify the hypotheses. Results - First, in relation to differences in the founder's personal characteristics, age, sales amount, and number of employees significantly impact business performance. Second, regarding the causal relation between the four factors for creating business performance, an innovative business model and social networking have supported the hypotheses, revealing that the more that a start-up founder has an innovative business model and social networking, the more the start-up firms are likely to have better performance (e.g., sales volume, employment, ROE, ROI, etc.). Although the founder's competency and sufficient cash flow have no significant relationship with business performance, the mean value was higher performance for high founder's competency and sufficient cash flow. Conclusions - This study provides basic data on policy support strategies of the Small and Medium Business Corporation, to help young entrepreneurs achieve their start-up business goals. It shows that young entrepreneurship startup firms should strive to explore ideas to satisfy customers' needs, and that changes in customer value and the continuous innovation of business model differentiation are required to actively respond to change management. Moreover, at the infant startup stage, they should activate social network programs to share information, thereby offsetting resource scarcity and managing business risk. Further, the establishment of a long-term vision and the implementation of training programs in related specific fields should be supported to strengthen founders' personal capabilities.

  • In the 17th and 18th centuries, when the Ryukyu kingdom had been invaded and controlled by Japan, some official texts about 'history' were documented. In that texts, there are some myths about the kings-Syunten(舜天), Eiso(英祖), Satto(察度), Syouhasi(尙巴志), Syouen(尙圓)-who founded dynasties of Ryukyu kingdom. This study attempts to delineate the features and meaning of those founder myths as a polotial discourse for kingship. The results of this study are as follows. 1. The founder myths are discourses to describe the genealogy of the Ryukyu kingdom as the result of Mandate of Heaven(T'ien Ming, 天命). 2. In ancient okinawa, the sun was a symbol of ruler. The king of Ryukyu kingdom was thought as 'son of the sun', 'Tedako(てだこ, 太陽子) in the time of Syou dynasty(尙王朝). But in the founder myths, the only one Tedako is Eiso. 3. In the myths, the 'historical' founders are described as the king for agriculture. They were said to make the farming instruments with iron and rule the spring water for farming. The iron and water for fariming was thought to represent the power of king and the kingship. 4. The writers of myths aimed to be separated from the mythical kingship of past Ryukyu(古琉球). So, they threw the idea of Tedako(=mythical kingship) into the prison of mythical ages by rewriting myth of King Eiso. Instead of it, they built up the new image of agriculture-king who rules and controlls the iron and water for good farming. The meaing of this change, from 'shiny sun' to 'cultural king', is that the abstract and general power of kingship was turned into a concrete and restricted power of kingship. On the bases of it, there was the confucian political ideas from China, T'ien Ming thought(天命論). Under the influence of not only China but also Japan, the writers of myths attempt to find a new way for their kingdom by reconstructing kingship with ruminating over the kingship of past. The myth of founders in the 17th and 18th Centuries shows the aspects of kingship of Ryukyu kingdom and tells us that those myths are the political discourses identifying kingship and Ryukyu kingdom.

  • Lee Byeong-hun was introduced to Hanjuhak when he was taught by Myeonwoo Gwak Jong-seok. It is assumed that Hanjuhak circles had a certain influence on formation of his ideas in that they had liberal tendency at that time. Lee Byeong-hun accepted Geummungyonghak developed by Gang Yu-wee of China and participated in Confucian Science Movement while excluding Confucianism. After he accepted western civilization and the ideas of Gang Yu-wee, no traces of Hanjuhak was found in his writing, but it is assumed that Hanjuhak might work as a nutritious element for his ideas. He thought that religious nature of Confucianism could be revived only when he left Neo-confucianism which changed Confucianism into a philosophy by insisting reason instead of God. So, he respected Confucius as a religious founder and left such concepts as reason and respect which were considered important in Neo-confucianism and valued disposition and faith in "Jungyong", a doctrine of the Mean. He considered Confucianism as religious and joined in religious practices such as praying and reciting scriptures. He insisted that filial piety indicates a filial son of the Heaven when interpreting the following passage: Shun (Chinese leader) is a filial duty, which is assumed that he was influenced by Christianity. He respected Confucius as the only religious founder and God as the God to make Confucianism a religion. It is believed that he considered only Confucius as a founder instead of traditional Confucian sages as religion such as Buddhism and Christianity has one founder. God he thought is related with the God in Christianity and furthermore accepted reincarnation of Buddhism which is contrary to Confucian ideas. According to "Gyeongseol" by Lee Byeong-hun, it was believed that he was engaged in religion based on a faith that Confucianism is a religion rather than he pursued Confucianism as a religion to find out a way of its survival.

  • Objective: The aim was to characterize the genetic diversity evolution of the registered Mexican Charolais cattle population by pedigree analysis. Methods: Data consisted of 331,390 pedigree records of animals born from 1934 to 2018. Average complete generation equivalent, generation interval, effective population size (Ne), and effective numbers of founders (fe), ancestors (fa), and founder genomes (Ng) were calculated for seven five-year periods. The inbreeding coefficient was calculated per year of birth, from 1984 to 2018, whereas the gene contribution of the most influential ancestors was calculated for the latter period. Results: Average complete generation equivalent consistently increased across periods, from 4.76, for the first period (1984 through 1988), to 7.86, for the last period (2014 through 2018). The inbreeding coefficient showed a relative steadiness across the last seventeen years, oscillating from 0.0110 to 0.0145. During the last period, the average generation interval for the father-offspring pathways was nearly 1 yr. longer than that of the mother-offspring pathways. The effective population size increased steadily since 1984 (105.0) and until 2013 (237.1), but showed a minor decline from 2013 to 2018 (233.2). The population displayed an increase in the fa since 1984 and until 2008; however, showed a small decrease during the last decade. The effective number of founder genomes increased from 1984 to 2003, but revealed loss of genetic variability during the last fifteen years (from 136.4 to 127.7). The fa:fe ratio suggests that the genetic diversity loss was partially caused by formation of genetic bottlenecks in the pedigree; in addition, the Ng:fa ratio indicates loss of founder alleles due to genetic drift. The most influential ancestor explained 1.8% of the total genetic variability in the progeny born from 2014 to 2018. Conclusion: Inbreeding, Ne, fa, and Ng are rather beyond critical levels; therefore, the current genetic status of the population is not at risk.

  • Religion is not fixed and permanent and is constantly transforming and changing phenomenon. But in some religions, religious culture happens that emphasize the original and authentic teaching of the founder and removes the other accumulations among the accumulated religious tradition. So some religious communities advocate the original teaching of the founder and insist that they are the orthodox and the others are heresy and make the theory of true transmission etc. Jongtonglon(宗統論) of Daesoonjinrihoe(大巡眞理會) looks similar to the theory of true transmission on the surface. The aim of this paper is the contribution to the understanding of Daesoon thought and the religious culture of Daesoonjinrihoe by studying the characteristics of Jongtonglon. I want to highlight on the characteristics of Jongtonglon by comparing it to Bubmaeklon(法脈論) of Korean Buddhism. Bubmaek(法脈) of Korean Buddhism is well showed in the constitution of Jogaejong(曺溪宗) that represents Korean Buddhism. The constitution says that Jogaejong considers SakyaMuni the main Buddha and Doyi (道義) the founder of Jogaejong and BojoJinul(普照知訥)·TaegoBou (太古普愚) the restorer of tradition and also says that Jogaejong succeedes Cheongheo(淸虛) and Buhyu(浮休). Between SakyaMuni and Doyi, there are several monks of Seocheon(西天)-28Choseol (祖說) and China-6Choseol(祖說). Jinul is highly praised for enhancing the atmosphere of performance of Jogaejong and Bou was regarded as the founder of Jogaejong since late Joseon dynasty. In modern times there were conflicts between Bojojongjoseol(普照宗祖說) and Taegojongjoseol(太古宗祖說), but today's Bubmaek(法脈) of Korean Buddhism was erected after the conflicts was controled. Jongtong of Daesoonjinrihoe was erected by Jo Jengsan(趙鼎山) Doju(道主) who was received Heaven's will through divine revelation. Dojeon(都典) succeeded Jongtong by Doju's will and he didn't say a word when he went to Heaven. So the succession of Jongtong is ended. The first characteristic of Jongtonglon of Daesoonjinrihoe is that the succession of Jongtong was decided by Heaven and has been expected from long ago. The second, Jongtonglon has the sacred characteristic which is not shown in Bubmaeklon. The third, the distinction between Yeonwun(淵源) and Yeonun(緣運) is not appeared in Bubmaeklon. The fourth, Jongtonglon has more anti-syncretic feature than Bubmaeklon. The fifth, Yeonun(緣運) and Bubmaeklon are different in that feature. As Jongtonglon occupies a prominent place in Daesoonjinrihoe, the understanding of it can contribute to grasp the doctrine and culture of Daesoonjinrihoe.

  • Due to the social problems including recent economic crisis and unemployment rate increase, the demand of business foundation market has been increased and, in the meantime, on the basis of the business foundation support policy of the government including youth foundation support policy and Small & Medium Business Administration foundation planning, business foundation market has been showing steady growth trend. With this enlargement of foundation market, as the accompanied increase of franchise market is expected, it is considered that the importance of more realistic and concrete research about franchise market be larger than before. This study considered brand image, main office support, foundation cost, information search activity as the advanced variable of effect on brand selection and established the cause of effect on brand selection by improving the existing advanced research, and its result is as follows. First, according to foundation business kind, age, sex, yes or no of marriage, there is some difference III the thought about brand image and foundation possibility. Second, Second, the most important factor of franchise contract intention is economical specificity. It is difficult to consider brand image, franchise support and information search activity as the property having a big effect on preliminary founder, and it was shown that the cost for franchise management(Consistency with initial foundation cost and self-capital, promotion cost, management fund, facility/equipment reinvestment, etc.) is an important property. Specially, it was shown that consistency with initial foundation cost and self-capital is the most important factor for preliminary founder.

  • Breast cancer contributes to approximately 23% of the cancer cases identified and 14% of cancer related deaths worldwide. Including a strong association between genetic and environmental factors, breast cancer is a complex and multi factorial disorder. Two high penetration breast cancer susceptibility genes (BRCA1 and BRCA2) have been identified, and germ line mutations in these are thought to account for between 5% and 10% of all breast cancer cases. The human BRCA1 gene, located on 17q, is involved in the regulation of cell proliferation by aiding in DNA repair, transcriptional responses to DNA damage and cell cycle check points. Mutations in this gene enhance cell proliferation and facilitate formation of tumors. Two mutations, the 185 deletion of AG and the 4627 substitution from C to A, are founder mutations in the BRCA1 gene for breast cancer in Asian populations. Allele specific PCR was performed to detect these selected mutations in 120 samples. No mutation of 4627 C to A was detected in the samples and only one of the patients had the 185 del AG mutation in the heterozygous condition. Our collected samples had lower consanguinity and family history indicating the greater involvement of environmental as compared to genetic factors.

  • A simulation study was conducted to evaluate a fine-mapping method exploiting population-wide linkage disequilibrium. Data were simulated according to the pedigree structure based on a large paternal half-sib family population with a total of 1,034 or 2,068 progeny. Twenty autosomes of 100 cM were generated with 5 cM or 1 cM marker intervals for all founder individuals in the pedigree, and marker alleles and a number of quantitative trait loci (QTL) explaining a total of 70% phenotypic variance were generated and randomly assigned across the whole chromosomes, assuming linkage equilibrium between the markers. The founder chromosomes were then descended through the pedigree to the current offspring generation, including recombinants that were generated by recombination between adjacent markers. Power to detect QTL was high for the QTL with at least moderate size, which was more pronounced with larger sample size and denser marker map. However, sample size contributed much more significantly to power to detect QTL than map density to the precise estimate of QTL position. No QTL was detected on the test chromosomes in which QTL was not assigned, which did not allow detection of false positive QTL. For the multiple QTL that were closely located, the estimates of the QTL positions were biased, except when the QTL were located on the right marker positions. Our fine mapping simulation results indicate that construction of dense maps and large sample size is needed to increase power to detect QTL and mapping precision for QTL position.

  • Autotransgenic manipulation with a growth hormone (GH)-construct is a potential approach to improving the growth rates of farmed fish. Here, we present the generation of GH-autotransgenic common carp Cyprinus carpio carrying a transgene comprised of the carp homologous GH gene and a ${\beta}$-actin regulator. Autotransgenic carp showed similar viability to their non-transgenic siblings. Early growth characteristics of founder autotransgenic carp up to 50 days postfertilization were highly variable among individuals; i.e., some fish exhibited significant growth depression, while others showed dramatic acceleration of growth, achieving greater than sixfold increases in body weight relative to their non-transgenic counterparts. Stimulated growth performance became more notable with age and many transgenic individuals of the largest class reached 5 kg within 8 or 9 months, which is at least 10 times heavier than the average body weight of communally grown non-transgenics. Four of six founder transgenic males were successful in passing the transgene to their $F_1$ offspring with frequencies ranging from 19 to 36%. Growth stimulations were also persistent in all $F_1$ progeny groups examined.
