크롬비트는 크롬 OS를 기반으로 하여 사용자 맞춤형 클라우드 서비스를 제공하는 스틱 PC이다. 기존의 크롬북이 이동성을 강조한 외부 인터넷 환경에 특화된 기기라고 할 때, 크롬비트는 스마트 TV구축 등을 비롯한 내부 인터넷 환경에 특화된 기기라고 볼 수 있다. 이처럼 크롬 OS를 실내와 실외에서 사용 가능하다는 것을 감안한다면 클라우드와 사물인터넷 등을 매개로 하는 4차 산업 혁명에 가장 근접한 OS 임에 틀림이 없다. 그럼에도 불구하고 현재 이 운영체제의 개발 속도와 더불어 보안 취약점 분석을 위한 방안은 전혀 마련되어 있지 않다. 그래서 본 논문에서는 취약점 분석 쉘 스크립트 실행을 통한 성능 향상 방안 마련과 크롬 OS의 보안 성능 개선 여부 확인을 살펴보고자 한다.

The purpose of this study was to identify structural properties of C.B.D and to provide direction that required for the plan and its development by analyzing land use patterns and its characteristics in the center of the city. In this study, the future planning elements and detailed land use of Seoul was analyzed, in regard to the spatial structural hierarchy and the function of downtown, by investigation of its current urban spatial structure. First, the characteristic of the land-use for merchandising facilities is that it is developed from west to east along the Jong-ro, Myungdong and Namdaemun, it shows high rate of the facilities along the horizontal axis. The large market area on this district would be the reason to the high rate of mechandising facilities. Second, the characteristic of the land-use for business facilities is that it is highly rated on the area passing through the Sejong-ro and Seoul station. The analysis result of our investigation is that the projects executed by Seoul city such as 'downtown maintenance planning' and 'downtown recreation program' strengthened functions of business and merchandising and promoted downtown shopping, leisure, tourism functions resulting activation of nearby market place and evaluated as maintaing the centrality of downtown Seoul well.

대전은 전국에서 R&D투자가 많은 지역으로 이는 출연연 및 출연연 출신 연구원의 기술창업의 증가로 나타나는 현상으로 볼 수 있다. R&D가 많이 투자됨에 따라 이에 따른 효율성에 대한 분석들이 많이 이루어지고 있으며, 주로 R&D 투자가 대한 지역내총생산, 기업의 생산성 등에 미치는 영향 즉 R&D투자의 효율성 분석을 많이 하고 있다. 본고에서는 지역 R&D투자가 기업의 생산성에 어느 정도 영향을 미치는 지를 분석하였다. 특히 지역특화(전략)산업 분야별로 분석하여 지역 R&D 투자의 효율적 배분을 위한 전략방안을 제시하고자 한다. 이러한 분석을 위해서 생산성에 대한 대리변수로 종업원 1인당 매출액 종업원 1인당 부가가치를 종속변수로 설정하였고, 독립변수로 연구개발비, 종업원 1인당 영업이익, 종업원 1인당 자본집약도 등의 변수를 다중회귀모형으로 실증분석 하였다. 분석결과 R&D투자가 매출액과 부가가치에 유의한 영향을 미치지만, 연구개발비가 매출액이나 부가가치 등 생산성 증가에 결정적인 요인으로 나타나지 않았다. 산업별 분석결과 정보통신, 바이오산업보다 부품소재 산업에서 결정계수가 높게 나왔다. 또한 조절회귀모형을 설정하여 조절효과를 분석한 결과 R&D투자는 매출액에 영향을 미치지만, 부가가치는 조절효과가 발생하지 않았다. 이는 지역 R&D투자의 효율적 배분 측면에서 투자의 활성화를 이루고 연구개발 투자가 실질적으로 기업의 생산성 증가에 기여할 수 있도록 견인해야 할 것이다.

This paper attempts to find out implications based on the comparative analysis of overseas expansion model between the Korean insurance companies and the German one. There are three types of the strategies of the overseas-expansion-model of insurer, i.e. customer-oriented localized strategy, niche market-oriented strategy, and growing market-oriented strategy. From the review of related literatures and through an interview conducted by the insurance specialist, the findings are some differences between Korean and German insurance companies, when they go into foreign insurance markets. Th significant differences between Korean and German insurers are a customer oriented localized strategy and niche market oriented strategy. The Korean insurer shows a strength on the overseas-expansion-strategy, but the most clients of the Korean insurer on overseas markets are also Korean companies and Korean immigrants. The Korean legal expenses insurance market is yet in its embryonic stage, while the German legal expenses insurance company is pushing ahead with a strategy focused on localization and niche market on the legal expenses insurance product. In conclusion, like a case of the German legal expenses insurance company, the Korean insurer needs a customer oriented localized strategy as well as a niche market oriented strategy on the overseas insurance market.

This paper investigates how industrial diversity affects unemployment and employment instability from the perspective of the regional economy. Through this analysis, we examine how the industry-specific policy to promote some industry strategically in most of areas affects the stability of the regional economy. We measure Herfindahl indexes using the 1993-2010 data of 16 regions in Korea, and use panel regression model for empirical analysis. The main results from this empirical analysis are summarized as follows. First, we confirm that the industrial structure of most regions has been changed to the direction of specialization in 1990s and to the direction of diversification in 2000s through analyzing the changes in the values of Herfindahl indexes during the given period. Second, we find from the estimation results of panel regression model that the higher industrial diversity in most of regions is, the lower the unemployment rate is. However, a statistically significant relationship between industrial diversity and employment instability only partially confirmed. Third, there exist high unemployment rate and employment instability in most metropolitan areas, but it is hard to say that this relationship is highly statistically significant. From the results of the empirical analysis, it is likely that the industry-specific policies such as the regional strategic industry development policies unlike policy goals make the unemployment rate to rise and economic instability to increase. From the viewpoint of employment aspects, the strategies to increase industrial diversity would be desirable rather than those to specialize in the industrial structure.

In this study, we performed to select the high growth potential agri-products in Ulsan City, Korea. For this, we carried out the location quotient and the regional growth rate differential analyses using the cultivated area data and the agricultural output data in 2000, 2005 and 2007. The location quotient analysis revealed that rice, pear and persimmon were classified as specialized agri-products. These results would be useful to reflect on a short-term policy in support for the agricultural activities of the local farmers because the specialized agri-products occupy a relatively high proportion in the region. In addition, the regional growth rate differential analysis showed that strawberries, persimmon, potatoes, corn and sweet potato are classified as growing agri-products whereas pear is classified as a competitive agri-product in the analysis based on agricultural output from 2000 to 2007. Based on cultivated area, strawberries, potatoes and corn are classified as growing agri-products whereas sweet potato is classified as a competitive agri-product. These results would be beneficial to establish a long-term agricultural policy in Ulsan City because these agri-products are further supported by the time series analysis, considering the nationwide trends and the production activities reflecting the preferences of consumers and the willingness of producers.

This paper investigates the properties and relative importance of Apparel Textile industry of Busan in terms of both the number of employees and the value-added, and then analyzes the relative technical efficiencies from the perspectives of space closeness such as consumption market, suppliers, living standards and clustering environments using the DEA model. The main outcomes are as follows. The Apparel Textile industry is still a key industry in Busan with relatively high intensity and high LQ (greater than one) in spite of the recent decrease between 2000 and 2005 both in the number of employees and the value-added. Those firms with consumption market showed higher efficiency in all kinds of efficiencies than the firms without the market, and further relatively higher efficiency than the firms with suppliers. In addition, the firms located in the higher living standards also showed higher values of efficiency compared with the firms in lower living standards. The policy implication from the results is that the strategic and selective investment should be made according to the relative efficiency and thus the traditional industry should be transformed to the high value added one with additional investment to utilize the scale efficiency.

The purpose of this study is to examine the characteristics and industrial structure and to present a future vision through analysis of industrial agglomeration, growth, and industrial efficiency targeting the Chungnam display industry nurtured by regional industrial policies since 2002. The industrial scale and aggregate status were analyzed through the business scale quotient and location quotient, and the growth and pace of structural change in the industry were analyzed through the industrial growth rate and change of industrial structure. Analysis results found the display industry shows its solid status based on industrial agglomeration. The RLQ, added value ratio, and employment coefficient have a relatively high comparative advantage. However, the growth rate has declined, and the pace of structural change has become lower. The regional competitiveness has been deteriorating. It is necessary to develop strategies to help the industry evolve into a convergence display industry to secure competitiveness by forming value chains. The regional industrial policy 'Regional Innovation Growth Plan' should be utilized to foster local industries that consider the regional characteristics and development directions and to promote the shared growth of related subsidiary industries through fostering specialized complexes for materials, parts, and equipment.
