As foreign investors' share holdings in Korean firms have dramatically increased since 1998 following the financial deregulation on the limit of foreign stock investment, the concern over the negative impacts the foreign investors would bring on the firms' financial policy has been growing too. Foreign investors were perceived to require the firms of excessive payments of cash dividends sometimes with threat of hostile takeover trials detering the firm from investing its cash flow in the physical facilities and RandD eroding their potential growth capabilities. We examine the impact of foreign investment on the firms' dividend policy using 234 listed firms' panel data over the sample periods of 1998 to 2005 employing various panel regression methodology. Foreign shareholders are found not to be related or even negatively related to the payout ratio(dividend/net income), but positively and statistically significantly related to the ratio of cash dividends to book of asset, negatively to the dividend yields. Considering the payout ratio is the most appropriate measure for the dividend payment, we can not support the arguments that the foreign investors' holdings have induced the excessive dividend level in Korean firms.

The IPCC (Intergovernmental Panel on Climate Change) recommended the importance of preventive measures against extreme weather, and heat waves are one of the main themes for establishing preventive measures. In this study, we tried to analyze the heat vulnerable areas by considering not only spatial characteristics but also social characteristics. Energy consumption, popu lation density, normalized difference vegetation index, waterfront distance, solar radiation, and road distribution were examined as variables. Then, by selecting a suitable model, SLM (Spatial Lag Model), available variables were extracted. Then, based on the Fuzzy theory, the degree of vulnerability to heat waves was analyzed for each variable, and six variables were superimposed to finally derive the heat vulnerable area. The study site was selected as the Daegu area where the effects of the heat wave were high. In the case of vulnerable areas, it was confirmed that the existing urban areas are mainly distributed in Seogu, Namgu, and Dalseogu of Daegu, which are less affected by waterside and vegetation. It was confirmed that both spatial and social characteristics should be considered in policy support for reducing heat waves in Daegu.

We take it for granted that strong sides defeat weaker counterparts, while predicting the outcome of the battles. But in modern war, we can find plenty of evidence that weak sides won against the strong. This phenomenon can be understood logically by the fourth-generation war theory. the North Korean does not give up its unification strategy, which is unification by force, even though its inferior power. It is continuing various political, social and military levels of provocations toward both the international community and South Korea. Recently, North Korea did nuclear test, launched ICBM test, provoked the DMZ, and expecting to continue the provocations of the fourth-generation war level. We have to understand the nature of North Korea's fourth-generation war threats and provocations that it is focusing on. Based on this, have a new understanding of the value of the Homeland Defense Reservists as fundamental measures as the fourth-generation war threat and supplement related systems. We can firmly refuse the balance of power and power shift of the Korean Peninsula through improved Homeland Defense Reservists. As the expected North Korea's the fourth-generation war threats, our Homeland Defense Reservists is a firm will of conduct war, and political-social-economic-military means, it is possible to display as the best alternative.

This study analyzes the cost fluctuation between cost in contract stage and cost in adjustment stage in defense R&D project. This research shows that certain costs hold with the cost fluctuation and their degree of influence. The results of first analysis show that 13 out of 17 costs have a relationship with the cost fluctuation. The estimate of direct labor cost is positive and significant at the 0.1% level(direct labor = 1.022, t = 38.355). The estimate of amount of cost paid to subcontractor is positive and significant at the 1% level(amount paid to subcontractor = 0.942, t = 51.894). The results of second analysis show that all the direct costs have a relationship with the cost fluctuation(The fact that cost system is focused on direct labor cost is a consideration in this analysis). The estimate of direct labor cost is positive and significant at the 0.1% level(direct labor = 2.014, t = 21.787). The estimate of amount of cost paid to subcontractor is positive and significant at the 0.1% level(amount of cost paid to subcontractor = 1.068, t = 15.636). This finding supports a proposal theory that cost system is focused on direct labor cost through actual proof analysis and an inducement that amount of cost paid to subcontractor is a way to reduce the R&D cost.

The art of dynamic images has experienced three development stages, including experimental films, recording art, and new media image. By introducing all kinds of new materials, new media to the art, and the art of dynamic images has created more freedom for art creation. With the development of digital information technology, dynamic image works have put forward an increasingly high requirement of visual art. The combination of dynamic images and visual illusion can give rise to different forms and expression methods, thus endowing artworks with more vigor. This paper provides an overview by sorting out the lineage and development of dynamic images in the background, as well as understanding the application and performance of contrasted visual illusion. Based on the understanding of the characteristics of visual illusion, we discuss the new characteristics of applying the theory of visual illusion to new media dynamic images in relation to the technical approach of dynamic images. Through the analysis of specific works of Telematic Vision, we search for its reasonable combination and find the appropriate technical means of implementation. We discuss how to use digital multimedia technology and spatial optical illusion to make the design more novel and impactful, and consider how the combination of digital dynamic image technology and visual illusion should be interpreted and applied.
