Recently international movements of labour as well as those of goods and other production elements such as capitals and technology have been increased rapidly under the process of glocalization. The huge amount of immigrant workers' in-flows makes increasing influences on regional economy in South Korea. This paper examines such impacts of immigrant workers on local labor markets, productivity. and industrial composition and innovation on the basis of analysis of empirical data and review of existing literature on the subject. Despite a problem of simplification, some reasoning can be listed as follows: First of all, the inflow of immigrant workers has an effect of job displacement among domestic simple workers, with duel effects on the status of native workers; secondly, Immigrant workers give a positive effect on local productivity, but only with low level of wage and of purchasing power; thirdly, the in-flow of immigrant workers seems to prevent existing industries from transformation towards new ones and/or from automation and innovation of production facilities, while there seems no clear relationship with foreign direct investments of local firms.

The study examines the effects that non-audit service and firm's ownership structure might have on the value relevance directly or indirectly. This investigation is based on prior research which suggests that the audit firms' non-audit services is likely to adversely affect investors' perceptions of the credibility of financial reporting and that corporate governance are likely to mitigate the adverse this kind of non-audit services effects. The sample consists of non-banking firms listed on the Korea Exchange that reported annual financial statements over the period from 2004 to 2008. In the setting, stock returns as proxy for capital market response, auditor quality(measured as the discretionary accruals) is endogenously determined. This study employs a structural equation model to take into account the endogenous variables under study. The analysis influences through the path analysis that ownership structure suppress the market response through audit quality and also the non-audit service have influence on the market response through audit quality. The results of this study contribute to the literature in the following ways. First, this provides direct evidence that there is a negative association between audit firms' client importance and the value relevance. Second, the findings that the negative association is attenuated for audit quality support the findings of prior studies which present that corporate governance provide higher credibility of financial reports.

As IT environment has changed, paths of information security in financial environment which is based on IT have become more diverse and damage caused by information leakage has been more serious. Among security incidents, personal information leakage incident is liable to give the greatest damage. Personal information leakage incident is more serious than any other types of information leakage incidents in that it may lead to secondary damage. The purpose of this study is to find how much personal information leakage incident influences corporate value by analyzing 21 cases of personal information leakage incident for the last 15 years 1,899 listing firm through case research method and inferring investors' response of to personal information leakage incident surveying a change in transaction before and after personal information leakage incident. This study made a quantitative analysis of what influence personal information leakage incident has on outcome of investment by types of investors by classifying types of investors into foreign investors, private investors and institutional investors. This study is significant in that it helps improve awareness of importance of personal information security by providing data that personal information leakage incident can have a significant influence on outcome of investment as well as corporate value in Korea stock market.

The theory of customer-based brand equity emphasizes the importance of brand awareness and brand image or associations in building a strong brand. Marketing scholars have recently begun to identify the two types of corporate associations, that is, corporate ability(CA) and corporate social responsibility(CSR) associations, which had long been conceptualized as a unidimensional construct of corporate image in the literature. In line with the new research stream, I'm developed a research model concerning how CA and CSR associations are related to credibility-based and benevolence-based trust, which in turn will affect emotional trust and consumer attitudes toward company. As for the hypothesized paths, the results confirm that all of the them are supported(H1-H6). First, CA associations have a significant positive relationship with credibility-based trust, and CSR associations are positively related to benevolence-based trust. Second, both dimensions of trust show strong and positive influences on emotional trust. In addition, credibility-based trust directly affect attitude toward firm in the foreign company. But credibility-based trust not affect attitude toward firm in the domestic company.

Illustrations in advertisement uses various social and cultural codes to stimulate the desire to buy in consumers in the first place, since this is an economic phenomenon orchestrated to sell a product. Hence, factors outside the product per se, such as tradition, social issues and class consciousness are introduced. Especially, in modern advertisement a strategy is adopted to differentiate standard products produced by mass production. In order to do so, such factors as mentioned above become as important as physical characteristics of the product per se and its usage value. As a result, phrases or images used for advertisement can have independent influences on the society irrespective of the sales effects on the product. In this respect, it is fair to state that advertisement reflects the phases and consciousness of a given period as a cultural phenomenon. Therefore, based on the premise of characteristics and roles attributed to the advertisement, this thesis proposes to make a comparative study on the images of women in commercial advertisement in Korea during Japanese Imperialism and China during Cultural Colonial period dating from 1900 to 1945. The starting point of this research will cover the period of foreign trade and Japanese Imperialism in Korea and interference of Western Power in China. It will also investigate on the birth of Korean advertisement by Japanese Imperialists and Chinese modern advertisement along with the modernization of Shanghai. Then, I propose to present the illustrations of women in advertisements based on comparative study of their characteristics and expressions as observed in several case studies both in Korea and China. Connotative meanings in such advertisement will be investigated in the context of political, economic and cultural dominance.

In the1970's, Korean movie industry was down because of widely supplied Television. During the time, directed by Kim Cheong-ki was Big hit at the box-office that is bring Korean feature animation industry back to life. In 80's, when new military regime started, SF animation was prohibited to be on air by government because that assumed have bad influences on children, and korean animation industry was faced with recession, such as various imported foreign animations which were on color TV and wildly provided video recorders. At that time, director KIM Cheong-ki try to overcome the recession of animation industry by producing, < David and Goliath>, which was based on the Bible. The Bible, was based on the historical facts and had written by the time flow, that made few changes while it was transformed to a feature animation. Animation does not only reproduce the reality as it is, but also analyzing the story to create a new reliable world, by changing characters, creating new supporting characters, and expanding and reducing of narrative. Despite of such an effort, didn't achieve it's goal at the box office and not satisfied audience either because it was excessive reproduction of the Bible, not standing on the basis of those days social and cultural environment and popularity. This study is aimed at confirming changed narrative shown Kim Cheong-Ki's, and compare it with two other animated, directed by others, so that suggest the new direction of the religious feature animation production.

This paper presents a numerical study on the rotordynamic analysis of a dual-spool turbofan engine in the context of blade defect events. The blades of an axial-type aeroengine are typically well aligned during the compressor and turbine stages. However, they are sometimes exposed to damage, partially or entirely, for several operational reasons, such as cracks due to foreign objects, burns from the combustion gas, and corrosion due to oxygen in the air. Herein, we designed a dual-spool rotor using the commercial 3D modeling software CATIA to simulate blade defects in the turbofan engine. We utilized the rotordynamic parameters to create two finite element Euler-Bernoulli beam models connected by means of an inter-rotor bearing. We then applied the unbalanced forces induced by the mass eccentricities of the blades to the following selected scenarios: 1) fully balanced, 2) crack in the low-pressure compressor (LPC) and high pressure compressor (HPC), 3) burn on the high-pressure turbine (HPT) and low pressure compressor, 4) corrosion of the LPC, and 5) corrosion of the HPC. Additionally, we obtained the transient and steady-state responses of the overall rotor nodes using the Runge-Kutta numerical integration method, and employed model reduction techniques such as component mode synthesis to enhance the computational efficiency of the process. The simulation results indicate that the high-vibration status of the rotor commences beyond 10,000 rpm, which is identified as the first critical speed of the lower speed rotor. Moreover, we monitored the unbalanced stages near the inter-rotor bearing, which prominently influences the overall rotordynamic status, and the corrosion of the HPC to prevent further instability. The high-speed range operation (>13,000 rpm) coupled with HPC/HPT blade defects possibly presents a rotor-case contact problem that can lead to catastrophic failure.

Korean shipping industry is ranked the fifth largest in the world in terms of deadweight tonnage after Greece, Japan, Germany and China with 55 million DWT as of year 2011, and its size of foreign exchange earning marked 30 billion US dollars. In respect of volume of seaborne trade, it has handled 99% of import and export cargoes. Korean shipping fleets have increased from 420 to 979 ships between year 2003 to year 2011. By reviewing through the relating literatures, it has been found that Shipping Funds under Ship Investment Company Act, and Tonnnage Tax System, worked as positive influences to increase the Korean shipping fleets. However, there is scant of research to examine the following two points: 1) weighing the decision making factors of ship investments for Korean shipping companies, and 2) weighing the influential factors of government shipping policies. In this respect, the aim of this study is to evaluate 8 decision making factors of ship investments for Korean shipping companies, and 8 influential factors of government shipping policies. For weighing the factors, the fuzzy methodology was adopted. As the results, for the side of decision making factors of ship investments, 'shipping market conditions and future prospects', 'ship's price and future prospects, and 'securing cargoes and future prospects' are ranked as top 3 factors. For government shipping policies side, 'shipping finance provided by lease companies', 'establishment of Korea Shipping Guarantee Fund', and 'establishment of Korea Shipping Finance Corporation' are verified as the important factors.

The randomness in the strength of a RC member is caused mainly by the variability of the mechanical properties of concrete and steel, the dimensions of concrete cross sections, and the placement of reinforcing bars and so on . Among those variations, the randomness and uncertainty of mechanical properties of concrete, such as compressive strength, tensile strength, and elastic modulus give the most significant influences and show relatively large statistical variations. In Korea, there has been little effort for the construction of its own statistical models for mechanical properties of concrete and steel, thus the foreign data have been utilized till now. In this paper, variability of compressive strength, tensile strength and elastic modulus of normal-weight structural concrete with various specified design compressive strength levels are examined based on the data obtained from a number of published and unpublished sources in this country and additional laboratory tests done by the authors. The inherent probabilistic models for compressive and tensile strength of normal-weight concrete are proposed as Gaussian distribution. Also, the relationships between compressive and splitting tensile strength and between compressive strength and elastic modulus in current KCI Code are verified and new ones are suggested based on local data.

Customer Relationship Management (CRM) in the media field is a specialcustomer-centered management method based on the information technology in order to build a long-term relationship with customers, users or subscripted people of media services. The purpose of this study is to examine and compare the various strategies and the characteristics of customer relationship managements of domestic media corporations in the era of the digital convergence. The data is analyzed by in-depth interviews with the CRM managements of newspapers, cable & satellite broadcasters and telecommunication corporations. The result of the study shows that the practicing CRM in the media field has an influence on the management performance and the management's support influences the practice of CRM. CRM is practiced differently according to the scale of the media corporations and revenue. Also the study presents that media corporations which wanted to improve CRM are going through trials and errors caused by the lack of experience of the CRM market in Korea. Therefore this study would provide CRM strategy for CRM marketers in Korea. Furthermore, this study presents concepts to media corporations which do not apply to CRM yet, and theoretical backgrounds which do. Finally, the implication of the study, limitations and problems are explained and discussed.
