Gun-Ho Song had been selected as 'the most respected person' in a survey targeting journalists. While being a journalist, Gun-Ho Song had directly experienced that the press submitted to government suppression and became commercialized receiving government benefits. In 1975, when Dong-A Ilbo(Daily News) submitted to the government suppression and conducted a mass of discharge of journalists, he felt responsibility and left the newspaper company. After that, he criticized more sharply the media subordinated to the power and capital. The core of Gun Ho Song's thought of the press is that the media should be independent from the power and capital contributing to nationalism and democracy. Also, he insisted that journalists should equip with historical consciousness and social scientific knowledge beyond roles like skilled workers. His idea of the press is still valid in the current media situation showing that journalists become skilled workers and independence of the press is risky. Looking into his activity and idea of the press can help seek for the right attitude of journalists and right roles of the media in the change of media environment.

The purpose of this study is to explore the journalist Song Kun-Ho's ideas of Korean Journalism. The journalist Song Kun-Ho was born in 1926 and passed away in 2001. He became a reporter in 1953 when he was a student at department of law of Seoul National University. He has worked for several media and resigned the executive editor at the Dong Ah Ilbo in 1975. At that time, while many reporters of the Dong Ah Ilbo struggled for the freedom of the press, he tried to protect reporters and independence of media. After his resignation of the executive editor, he wrote many columns and several books for Korean nationalism and the democracy of journalism. Instead of working for the authoritarian military regime, he chose a lonely and rough life as an intellectual journalist in action. Finally, he, as a president, established the Hankyoreh daily newspaper which was funded by tens of thousands citizens. He passed away in 2001. His ideas of Korean journalism are nationalism, democracy, and independency. These ideas are very important to restore democratic journalism which has been at risk during the Lee Myung-bak administration.

In this paper, an efficient algorithm for computing in the MPEG/audio Layer Ⅲ (MP3) encoder is proposed. The proposed algerian performs a full-band 1024-point FFT by computing 32-point FFT's of 32 subband outputs. To reduce the aliasing caused by the analysis filter bank, an aliasing cancellation butterfly is developed. A major benefit of the proposed algorithm is the computational saving. By using the proposed algorithm, it is possible to save 40~50% of computations for FFT, which results in about 20% reduction of the PAM-2 complexity.

The present studt was performed to investigate the effect of treatment and samples of human follicular fluid (hFF) on the development in vitro of mouse embryos. The two cell stage embryos collected at 40 h post-hCG injection were cultured in the modified human tubal fluid (m-RTF) containing 15% synthetic serum substitute (SSS) or human tubal fluid (hFF) for up to 3 days at $37^{\circ}C$ in 5% $CO_2$ incubator. Also the composition of hormone, total protein and protein pattern of hFF samples were analyzed. The developmental rate of mouse embryos developed to blastocyst were not significant difference in the m-RTF containing 15% hFF filtered with 0.22 or 0.8 ${\mu}m$ syringe filter, however, the embryos cultured in the m-RTF containing inactivated hFF were significantly (p<0.05) developed at the high rate to blastocyst than those containing fresh hFF and SSS. The in vitro developmental rate to blastocyst and hatched blastocyst in the m-RTF containing 15% hFF sample A (90.5 and 85.4%, respectively) and SSS (79.4 and 75.3, respectively) were significantly (p<0.05) increased, compared with hFF sample B (64.2 and 54.1 %, respectively). The hFF sample A tended to be higher concentration of LH, FSR, total protein and the ratio of progesterone/$E_2$ and lower concentration of $E_2$ and progesterone than the hFF sample B, but there were no differences in the protein pattern between the two hFF samples. The results of these study suggest that the addition of hFF to the culture medium enhances the development in vitro to blastocyst and hatched blastocyst, but the in vitro developmental rate of mouse embryos is different between hFF samples.

As an initial step toward better understanding of the molecular mechanism of estrogen-dependent growth in myoma, an optimal primary cell culture condition has been developed and examined by this study. Myoma and myometrium were cultured by two different methods. Culture stability and $E_2$-responsiveness in stable culture were studied. The culture of digested tissue pieces(Method 2) was found to be a stable culture method for the myoma and myometrium showing a favorable response to estrogen. mRNA expression of PR, IGF-1 and IGF-1 receptor genes was enhanced by $E_2$. The gene responses to $E_2$ were higher in myoma compared with myometrium. Moreover, these responses were more expressive in tissues than in the surrounding cells in primary culture of normal myometrium and myoma, implying a vital role of cell communication through the extracellular matrix in maintaining the estrogen-responsiveness. The development of an improved cell culture system for myoma provides an in vitro tool to further investigate the basis of the tumor formation.

This paper aims to study the effect of academia-industrial cooperation on the technical innovation of small and medium-sized companies. A survey was conducted on about 1,100 businesses located in the Sihwa-Banwol industrial estate to analyze the consequence of three factors of academia-industrial cooperation. the joint use of equipments, technological support of universities to businesses, and cooperative technological development through technical guidance-on entrepreneurial capability and their knowledge-absorption ability, and ultimately on their technological innovation,. The validity of the survey result was tested through the Structural Equation Model. On the basis of the comparison between companies which have participated in academy-industry cooperation and companies which have not, this paper suggests that venture businesses should take advantage of the cooperation with universities to boost their competitiveness. The analysis of the three individual factors of the academy-industry cooperation based on the Structural Equation Model shows that all of them have remarkable influence on entrepreneurial capability, but that they don't have as much impact on businesses' knowledge absorption ability. However, the outcome of technological innovation of businesses is primarily influenced by entrepreneurial capability rather than their knowledge absorption ability. The survey also shows that the three factors of the cooperation have an equal impact on the competitiveness of companies regardless of their business type or their products' growth stages. As the companies involved in academy industry cooperation outweigh other businesses, in terms of technological innovation, the numbers of new product development, and the numbers of their process improvement cases, this paper argues that new strategies should be taken for the businesses to fully take advantage of academy-industry cooperation.
