  • This study examines the impact of government funds to venture capital on investment in early-stage firms. We provide novel explanations about this relationship focusing on mechanisms by which government funds influence the perceived uncertainty, decision about investment priority, scale economy of investment, information asymmetry in investment decision, and capital expense. We argue that venture capital's investment in early-stage firms increases as government funds increase and as government funds are explicitly directed for early-stage firms. However, we further claim that the impact of government funds on early-stage investment will be decreasing as their size increases and finally be reverted to negative impact beyond a certain amount of funds to show inverse-U relationship. Our empirical examination using data from 105 Korean venture firms active as of 2013 consistently supports the claims. This study contributes to the venture capital literature by providing novel arguments about mechanisms and effects of policy intervention in venture capital. In practice, we expect our results will provide an opportunity for relevant policy makers to review their venture support policy based on empirical evidences for policy effects.

  • The purpose of the study was to compare the differences among phases accoring to the gait time on the heel height during gait, investigate the effect on ROM of the lower limb on gait time. Ten female college students in their 20s participated in the study, and variables were calculated through 3D gait analysis on height of heel. As a statistical method, one-way ANOVA was performed for the differences between the three heel heights, and multiple regression analysis was performed to determine the effect of gait time on the ROM. As a result of the study, phase 2, the higher the heel, the longer the gait time, but phase 3, the higher the heel, the shorter the gait time. As a result of analyzing the effect of gait time on the ROM of the lower limb, in phase 2, the greater the ROM for the ankle and knee joint in 1 cm, and for the ankle joint in 5 cm, the longer the gait time. In phase 3, the greater the ROM for the hip joint in 1 cm, the longer the gait time, and the smaller the ROM for the ankle joint in 10 cm, the longer the gait time. Therefore, in the case of high-heeled shoes, it is suggested that the control of the ankle joint is important.

  • TIG remelting was performed to harden the surface of automobile earn shaft. Multipass remelting was conducted in longitudinal direction under argon gas atmosphere. The microstructure of as-east earn shaft was gray iron which consisted of flake graphite and pearlitic matrix. The remelted area had microstructue of both fine pearlite and ledeburite structure that consisted of globular austenite and $Fe_3C$. Hardness for as-cast earn shaft had HRc 25~28, however it increased at remelted area to HRc 53~55. Black line was found at heat affected zone next to the fusion line, that is remelt area of previous pass, during multipass remelting. Black line was identified as graphite, which was transformed from $Fe_3C$. in the ledeburite structure. It is observed that all graphites were nucleated at $Fe_3C$. and matrix interface. High density energy laser remelting process was also applied to verify whether black line could be eliminated. However, black line was still existed as observed in TIG remelting process. Regraphitization was simulated on the ledeburitic structure specimen using Gleeble 1500 with conditions of 1100 and 100$0^{\circ}C$ for 0.5, I, 3, 5 and 1Osee. From the fact that graphite was formed even at the simulation condition of 100$0^{\circ}C$ for 0.5sec, it is seen that regraphitization is an inevitable phenomenon generated whatever processes used during multipass overlap remelting.

  • A three-year (2000-2002) survey on consumer's awareness and perception of genetically-modified (GM) foods was conducted on random samples of Korean consumers. More than 65% of the respondents were exposed to some information related to GM foods. The greatest benefit of the development of GM foods was thought to be their remedy of potential food shortages in the future. More than 90% of Korean consumers wanted GM foods to be labeled. About 18% of the respondents would buy GM foods voluntarily, whereas over 46% would not until they knew more about the product. Only 39% of Korean consumers were found to have realized that food items origination from plants contained genes. More consumers responded that they would not buy herbicide-resistant GM soybean and buy vitamin-enriched GM soybean instead. Many Korean consumers appeared to make decisions of acceptance or rejection of GM foods not on the basis of biotechnology, but on the basis of the word(s) used to describe the products, such as herbicide and vitamin. Only 4% of Korean consumers responded that GM foods were the greatest threat to the safety of Korean foods.

  • There is an increasing attention by scholars and policy makers that university campus can be the key space for the location of high-tech companies and research facilities as well as the promotion of university-industry collaboration activities. There is a tendency that science parks in the UK have a close connection with neighboring universities on the basis of university-industry collaboration activities. Moreover, the role and importance of the university in the evolution process of science parks has been rapidly increased since the 1990's. Recently, the UK government started to push ahead with the university enterprise zone programme, as a new type of enterprise zone, in order to promote university-industry collaboration and local economic development. In this regard, the Korean government also needs to pay attention to the new role of universities, especially universities located in non-capital areas, for not only strengthening the competitiveness of universities, but also fostering regional and national economic development.

  • Death of non-growing microorganisms in saline was studied to observe the inhibitory effect of NaCl in foods on the viability of microorganisms. When Leuconostoc mesenteroides LA10, Staphylococcus aureus B31 and Escherichia coli B34 were incubated in McIlvaine buffer with 0, 10, 20, 30% NaCl at $30^{\circ}C$, they survived best at pH 6, 5, 7, respectively. The survival of 5 lactic acid bacteria, 9 other bacteria and 2 yeasts was tested at pH 5, 6, 7 with 10% NaCl. Gram-positive bacteria survived in saline better than Gram-negative bacteria, and lactic acid bacteria and S. aureus survived better than other bacteria. The number of survivors decreased as concentrations of NaCl increased and as pH moved to acidic or alkaline side from the above-mentioned. When L. mesenteroides LA10 was incubated in saline with those materials which are known to protect microorganisms from the killing effect of NaCl, protective effect was not observed.

  • The phenomenon of international migration since the 1980s comes to be born 'multi-cultural families support law' due to the foreign workers' inflow into labor market and to a rise in married female immigrants caused by globalization and diversification. Accordingly, the purpose of this study is to examine who are participants? given being led to the enactment of 'multi-cultural families support law' by which the social issue called multi-cultural family is highlighted as the public agenda. Also, the mobilization will be selected and explained among three types in mobilization model, outside initiative model, and inside access model in the process of driving by confirming it as the government's formal agenda out of social issues. With having the case characteristics in mind, the aim is to research by choosing a case analysis method that uses research theses & books, newspaper, daily newspaper, election pledges, civic group, internet, and seminar data based on the existing theory and model. The temporal scope is limited to the one from the time as saying "revise the Overseas Korean Act of opposing the banishment of migrant workers" in November 2003 to February 2008 when 'multi-cultural families support bill(alternative plan)' is legislated with agreement by the 7th plenary session for the 271th provisional session of the National Assembly.
