The purpose of this study is to empirically investigate the role of capitalized intangibles such as patents, copy rights and R&D and non-capitalized intangibles such as advertising expenses and labor-related expenses, which are considered to be important to generating future excess profits, on the valuation of IPO shares. This study examines 125 firms which went public during 1992 - 1998. The result suggests that advertising expenses do not have significant influence on the offer price and the market price of IPO shares. On the other hand, R&D and labor-related expenses play important role in determining the offer price and the market price of IPO shares. In case of capitalized intangible assets, they we important factors in determining the market price but not the of for price. This study suspects that the Securities and Exchange Law of the Korean Securities Exchange Commission potentially contribute to the result of no effect of capitalized intangibles (except R&D) on the offer price by underwriters. According to the Law, any intangible assets which are considered to be irrelevant to the valuation of IPO shares must be exclued. This is very ambiguous and potentially cause underwriters to exclude any intangibles difficult to measure their value. However the market considers capitalized intangibles to be important, as suggested by the result of this study. To reduce this valuation asymmetry, it is important to reveal detailed information regarding the valuation of assets, in particular, intangible assets to the public.

This paper examines the effect of unique underwriter lockup on the initial returns of an initial public offering (IPO) in the Korean Securities Dealers Automated Quotation (KOSDAQ). Underwriter lockup induces underwriters to underprice IPOs and stabilize aftermarket prices. The inducement is explored with respects to the mixtures of distributions of the initial returns consistent with underpricing and stabilization. Whether the inducement is meaningful when other factors are controlled is also explored. These explorations provide evidence that underwriter lockup leads to more positive average initial returns in the three aftermarket months.

While there exists voluminous literature on the internationalization of the firms, it has focused on mature firms or born-global firms. There is still a lack of research on firm that is in the growth stage between venture and mature firm. To fill this gap, this paper focuses on the newly public firm which is enter the stock market through initial public offerings (IPO). Specifically, I examine the relationship between the early listing and internationalization. In the venture firm aspect, the decision of the IPO necessary to allow to change organization structure, ownership and take a risk from environmental movements. This paper suggests early listing is a behavior of entrepreneur orientation. According to empirical results, there is a positive relationship between early listing and internationalization. It implies that early listing may help international expansion by sourcing finance, reputations from market. Furthermore, this study emphasizes the importance of financial slack resources to international expansion. I conclude that ventures need not only early entering in stock market but also securing sufficient financial slack resources to achieve sustainable growth in the international market.

In this paper, we propose an optimal design method for a dual reflector antenna(DRA) using the Genetic algorithm. In order to reduce the computational burden during the optimal design, we exploit the iterative physical optics(IPO) to calculate the surface current distribution at each reflector antenna. To improve the accuracy, we consider the shadow effect by the structure and the coupling effect by the multi-reflection based on the iterative MFIE(Magnetic Field Integral Equation). To reduce the number of design variables and generate a smooth surface, we use the Bezier function with the control points, which become the design variables in this paper. We adopt the HPBW(Half Power Beam Width), the FNBW(First Null Beam Width), and the SLL(Side Lobe Level) as the objective or cost functions. To verify the results, we compare them with the those of the commercial tool.

New drug development requires 10 to 15 years of long time and more than $ 1 billion in funding, ranging from basic research${\rightarrow}$preclinical medicine${\rightarrow}$clinical medicine${\rightarrow}$product approval${\rightarrow}$sales. Many new drug development bio-venture companies will continue to pursue new drug development with funds secured through listing on the securities market. This study focuses on the impact of the listing on the market of bio-venture companies in the development of new drugs. It is necessary to determine whether the increase in registered patent, preclinical, clinical and technology transfer contracts at the time of listing (D) The results of this study are as follows. We also analyzed whether the registered patent, preclinical, and clinical effects had significant effect on technology transfer contracts at two years after listing and listing. The results of the analysis are as follows. First, Korea's new drug development bio-venture firms increased their registered patents but did not increase their pre-clinical, clinical and technology transfer contracts. Second, at the time of listing and two years after listing, pre-employment has a significant effect on Korea's technology transfer contracts and has a significant effect on overseas technology transfer contracts. However, registered patents and clinics have significant influence on technology transfer contracts. Korea 's new drug development bio-venture firms showed patent increase despite the stock market listing, but pre-clinical, clinical and technology transfer contracts did not increase. In order to strengthen technological commercialization of new drug development bio-venture companies in the future, it is required to establish R & D strategy for efficient use of IPO subscription funds, open innovation through strengthening industry-academia-partnerships, and more sophisticated preclinical and clinical strategy establishment.

The purpose of this study is to examine whether the existence of related personnel in KOSDAQ technology special listed firms has a signal effect on the market and affects performance when listed. The KOSDAQ technology special listing system is a system introduced to enable future growth by securing financing through corporate public offering based on the technology and marketability of technology-based startups and venture companies. As a result of analyzing 135 special technology companies listed from 2005 to 21 (excluding SPAC mergers and foreign companies) whether or not related personnel affect corporate value and listing period when they are listed, it was analyzed that the presence of related personnel did not significantly affect corporate value or listing period. The same was found in the results of the verification by reducing the scope to related personnel such as public officials and related agencies. However, under certain conditions, significant results were derived from the presence of related personnel on the listing of companies listed in special technology cases. It was found that the presence of related personnel and VC investment had a significant effect on corporate value, and in the case of bio-industry, there was a slight significant effect on the duration of listing. This study is significant in that it systematically analyzed the signal effect of the existence of related personnel for the first time for all 135 companies. In addition, as a result of the analysis, the results suggest that internalized efforts to secure technology and marketability are more important, such as parallel to VC investment, rather than simply recruiting related personnel.

This study analyzes newly listed companies on KOSDAQ from 2011 to 2020 for both firms having experience in attracting venture investment before listing (VI) and those without having experience in attracting venture investment (NVI) by examining differences between two groups (VI and NVI) with respect to both the level of listing performance and that of firm performance (growth) after the listing. This paper conducts descriptive statistics, mean difference, and multiple regression analysis. Independent variables for regression models include VC investment, firm age at the time of listing, firm type, firm location, firm size, the age of VC, the level of expertise of VC, and the level of fitness of VC with investment company. Throughout this paper, results suggest that listing performance and post-listed growth are better for VI than NVI. VC investment shows a negative effect on the listing period and a positive effect on the sales growth rate. Also, the amount of VC investment has negative effects on the listing period and positive effects on the market capitalization at the time of IPO and on sales growth among growth indicators. Our evidence also implies a significantly positive effect on growth after listing for firms which belong to R&D specialized industries. In addition, it is statistically significant for several years that the firm age has a positive effect on the market capitalization growth rate. This shows that market seems to put the utmost importance on a long-term stability of management capability. Finally, among the VC characteristics such as the age of VC, the level of expertise of VC, and the level of fitness of VC with investment company, we point out that a higher market capitalization tends to be observed at the time of IPO when the level of expertise of anchor VC is high. Our paper differs from prior research in that we reexamine the venture ecosystem under the outbreak of coronavirus disease 2019 which stimulates the degradation of the business environment. In addition, we introduce more effective variables such as VC investment amount when examining the effect of firm type. It enables us to indirectly evaluate the validity of technology exception policy. Although our findings suggest that related policies such as the technology special listing system or the injection of funds into the venture ecosystem are still helpful, those related systems should be updated in a more timely fashion in order to support growth power of firms due to the rapid technological development. Furthermore, industry specialization is essential to achieve regional development, and the growth of the recovery market is also urgent.

This study analyzes the innovation performance of venture firms according to existence of venture capital investment, and according to type and ownership of venture capital. Venture firms are IPO firms that are registered on KOSDAQ between the year 2000 and 2016. They are categorized as corporate venture capital-backed firms (CVC) and independent venture capital-backed firms (IVC). Using patent data from KIPO (Korean Intellectual Property Office), we employ the number of patents and the citations per patent as the measurement of the innovation output. We find the positive association between the venture capital-backed firms and the number of patents before going public. Corporate venture capital-backed firms are positively associated with the number of patents before and after IPO. However, we do not find strong evidence between the number of citations and the existence of venture capital investment or the type of venture capital. Lastly, we provide an inverse U-shaped relationship between the innovation performance and venture capital's ownership. In other words, the innovation output, both the number of patents and the number of citations, gradually increases as the venture capitalist's ownership increases, but also shows a decrease pattern, suggesting that the venture capitalist's ownership does not only spur the innovation but also gives a negative effect on venture firm's innovation output such as excessive intervention. Overall, we reveal that the most important factor for the innovation performance is not the existence of venture capital investment or the type of venture capital, but the ownership of the venture capitalist.

To investigate the effects of weir construction on sediment characteristics of river bed, we conducted sediments sampling on the 9 locations near the weir, Kangchun, Yuju and Ipo in Namhan-River. Physical and chemical characteristics of sediments were analyzed by measuring particle size distribution, water content, Ignition loss, COD (Chemical Oxyzen Demand), TOC (Total Organic Carbon), TP (Total Phosphorus), SRP (Soluble Reactive Phosphorus) and TN (Total Nitrogen). Particle classification of all three weir sediments showed sandy loam that was caused by the river bed dredging. Due to the presence of weir, Ignition loss, COD, TOC, TP, SRP and TN showed similar trend such as the concentrations of upward weir had higher than those of downward weir. For the case of SRP concentration and C/N ratio, however, there is not much difference in the sediment characteristics compared to the those of sediments before weir construction. Therefore, It can be predicted that there are little effects of weir construction on sediment characteristics. However, weir construction could influence water quality of the river by controlling the transport and the accumulation of suspended materials from rainfall. Therefore, more intensive monitoring is required to examine the magnitude and patterns of sediment accumulation which could influence overlying water quality.
