The purpose of this paper is to investigate office location dynamic in Seoul and to analyze comparatively the office activities of emerging office centers. Since mid 1980s, the expansion of office employment and spatial differentiation of the office-type jobs have changed the employment and spatial structure of Seoul. The major employment centers are CBD, Kangnam district and Youido. Among these, CBD and Kangnam have developed as the two leading centers of Seoul. Youido, the typical office-oriented center, shares CBD functions especially specializing security business. Selective decentralization of offices made qualitative differences among the centers. In spite of vigorous office decentralization, CBD has kept the principal offices of finance and insurance, travel agencies, advertising agencies, management consulting firms, major public institutions and headquarters of upper 100 companies in Korea. But the offices of producer services such as law, architects, engineering and computer consulting and real estates and headquarters of upper 5000 companies in Korea have been decentralized dominantly to Kangnam.

Over the years a lot of organizations or enterprises are spending the majority of their IT budgets on IT resources procurement and maintenance. IT resources are typically duplicated in each Region, Division, and/or Business Unit. The biggest sources of cost savings come directly from the reduction in maintenance cost and the elimination of duplicated resources. Global corporations are investing heavily in shared services implementations in order to stay competitive in an industry environment. A number of financial services firms have turned to IT shared services to reduce the level of IT asset and infrastructure redundancies. Recently, Korean financial services industry is moving to diversification(bank, securities, insurance, etc.) and consolidation(M&A, strategic alliance, etc.), and wants the elimination of duplicated IT resources. This research is intended to find out and demonstrate the factors having a significant effect on adoption of IT shared services center in finance services industry.

In this article we examine a unique data set of intraday fair disclosure(FD) releases to shed light on market efficiency within the trading day. Specifically, this paper analyze the response of stock prices on fair disclosure disseminated in real-time through KIND(Korea Investor's Network for Disclosure) on Korea stock exchange during the period from January 2003 to September 2004. We find that the prices of stock experiences a statistically and economically significant increase beginning seconds after the fair disclosure is initially announced and lasting approximately two minutes. The stock price responds more strongly to fair disclosure on smaller firm but the response to fair disclosure on the largest firm stock is more gradual, lasting five minutes. We also examine the profitability of a short-term trading strategy based on dissemination of fair disclosure. After controlling for trading costs we find that trader who execute a trade following initial disclosure generate negative profits, but trader buying stock before initial disclosure realize statistically significant positive profit after two minute of disclosure. Summarizing overall results, our evidence supports that security prices on Korea stock exchange reflects all available information within two minutes and the Korea stock market is semi-strongly efficient enough that a trader cannot generate profits based on widely disseminated news unless he acts almost immediately.

지불,결제와 함께 대표적인 전자상거래 솔루션의 하나인 보안분야는 올해 어느해보다도 고속성장을 누릴 전망이다. 금융과 증권업체가 인터넷 트레이딩과 뱅킹서비스를 본격화하고 인터넷 쇼핑몰업체가 완벽한 개인정보 보호를 위해 보안 솔루션 업그레이드를 적극 검토하고 있기 때문이다. 여기에 올해 대기업을 중심으로 기업간 (B to B) 전자상거래 시스템이 붐을 이루고 그동안 보안 사각지대였던 정부 등 공공기관이 보안시스템 구축에 적극 나서면서 보안업계는 사상 유례없는 호황을 누릴 것으로 보인다. 올해 보안업계의 화두로 떠오를 5대 이슈를 예측해본다.

Utilizing the patent application data between 1997 and 2002, this study focuses on analysing the impact of patents on firm value. Especially we attempt to examine the difference of patents between venture firms and general firms. This paper first shows that the number of the patent applications of general firms listed on the securities market are more than those of venture firms listed on KOSDAQ. It is thought that this result is originated from facts that the size of firms of the securities market is usually bigger than the firms of KOSDAQ and that these large firms could manage R&D more efficiently. Second, this paper reports that there is no difference in the ratio of patent maintenance between venture firms and general firms. Both venture firms and non-venture firms would do their best to keep their patents after patent regisration. Third, in the regression of patent index and firm growth, we find that the excellence of patent and the number of patents per employee would have an impact on the growth of firms. Fourth, the regression of patent index and profitability shows that the excellence and the number of patents per employee might have an effect on the profitability of firms.

This study is to identify the influence of major variables that affect the participation intention of securities type crowdfunding investors and how participation intention and perceived behavioral control affect investors' herd behavior including indirect effect analysis based on the theory of planned behavior. The ultimate purpose of this study is to understand the investment behavior of securities type crowdfunding investors and to help the relevant parties to develop various policies and business plans to revitalize the system and protect investors. An online survey was conducted on people who are interested or have experience in securities type crowdfunding to receive a total of 276 responses. Excluding outliers, a total of 261 responses were taken into account for the final analysis. For the data analysis, structural equation model analysis using SPSS 22.0 and Amos 22.0 statistical package was conducted. As a result, two of the major variables of the theory of planned behavior-attitude and subjective norm-have been found to have a positive effect on the participation intention of securities type crowdfunding investors. And after analyzing the indirect effect, the participation intention was found to play a mediating role between attitude, subjective norm and herd behavior. However, the perceived behavioral control presented as a major variable of behavioral intention in the theory of planned behavior showed that the effect on participation intention was statistically insignificant. Instead, it was found to have a direct positive effect on herd behavior. This is significant because it empirically confirmed that even if investors perceive securities type crowdfunding as easy to participate, perceived behavioral control does not seem to have a significant impact on participation intention because securities type crowdfunding is an investment in an early-stage business with a high risk of loss. On the other hand, the study has great significance in that it empirically confirmed that domestic securities type crowdfunding investors perceive the funding progress information provided by the platform as a signal and imitate many other investors, showing herd behavior when they actually make an investment. It is expected that this study will provide meaningful insights for the policy making of crowdfunding supervisory offices and platform operators by empirically identifying major variables that influence the participation intentions and herd behavior of domestic securities type crowdfunding investors.
