Recently, the construction companies are forced to cut down the investment amount due to increasing financial problems caused by severe recession and restructuring in the financial market as well as the long-term depression of the construction industry. To overcome this type of problems, a great many efforts have been made. An alternative may be adopting the advanced financing methods. However, during the course of enforcing process of the financing methods, many problems are revealed without any proper solutions being proposed. Therefore, the fundamental problems need to be solved through comprehensive and systematic approach under the changing environment of construction financing. In this paper, as a result of reviewing some financing methods such as ABS, REITS, and Project Financing, multiple business strategies for construction companies to cope with the changing construction market are found in the sense of effectiveness in implementing construction projects. Further, this paper presents diversified financing methods for the effective practice of construction projects through combination of above mentioned methods, and also proposes improvement plans to strengthen the financing function for the construction industry.

Service industries nowadays have become the subject of a scientific research. However, unlike research on manufacturing, there has not yet been a broader presentation of important aspects theoretically and methodologically. The importance of service sector in both national and global economies has grown significantly. An active participation of service industries in the internationalization process, notably by licensing and FDI, has occurred over time. But a few sub-sectors still dominate on this process, for example, financial institutions such as banks, securities, and insurance as well as producer services in advertising and accounting. On the other hand, personal services that are owned by small- and medium- sized firm have limited capabilities in their transnational transfer. This paper attempts to examine various factors influencing decisions for these small- and medium- sized Korean beauty firms in entering to the foreign markets. Determining factors for these firms in the engagement of internationalization depends largely on competitive advantages in both domestic and host countries, and they may be different from those in the sub-sectors mentioned above. Based on previous researches, i identified three categories of independent variables(characteristics of firms, managers, and competition) that can influence decisions to enter to the foreign markets. Seven hypotheses have been tested by using a sample of beauty firms in Daegu city and Kyungbuk province. The results show that the intention of these firms to enter to the foreign markets is significantly influenced by the factors of the innovative character of CEO's, the competitiveness of firms, and size of firms.

Utilization of unmanned aerial vehicles (UAVs) are rapidly expanding to various fields ranging from defense, industry, entertainment and personal hobbies. Due to the increased activities of unmanned airplanes, many security problems have emerged, including flight path errors to undesired destinations, secondary threats due to exposed securities caused by the capture of unmanned airplanes in hostile countries. In this paper, we find security vulnerabilities in UAVs such as GPS spoofing, hacking captured video information, malfunction due to signal attenuation through jamming, and exposure of personal information due to image shooting. In order to solve this problem, the stability of the unstructured data is secured by setting the encryption of the video shooting information section using the virtual private network (VPN) to prevent the GPS spoofing attack. In addition, data integrity was ensured by applying personal information encryption and masking techniques to minimize the secondary damage caused by exposure of the UAV and to secure safety. It is expected that it will contribute to the safe use and stimulation of industry in the application field of UAV currently growing.

Recently the business environment surrounding the financial investment industry is changing rapidly, and the demands of customers (diversity and the cycle of change etc.) are getting shorter. In this context, it can be said that companies are forced to adopt an agile management environment. In particular, non-face-to-face channels, including MTS, is adopting the agile system into the digital finance sector from a company-wide and strategic perspective. This study analyzed the effects of MTS services' environment quality on customer satisfaction and continuous intention to use for MTS users who are rapidly increasing under the agile management environment in the financial investment industry. This study surveyed the quality of service environment (accessibility, convenience, design, security), customer satisfaction, and continuous intention to use for 350 MTS users. First, accessibility, convenience, and security of MTS service environment quality had a positive effect on customer satisfaction, and design was rejected Second, customer satisfaction has a positive effect on continuous intention to use. Third, convenience and security of MTS service environment quality have positive effects on continuous intention to use, and accessibility and design were rejected. The results of this study, together with demographic analysis, are expected to provide useful implications for MTS activation studies and securities firms' strategies.

This paper estimates a translog cost function for the Korea's banking industry and derives various implications on the prospect for the Korean banking structure in the future based on the estimated efficiency indicators for the banking sector. The Korean banking industry is permitted to operate trust business to the full extent and the security business to a limited extent, while it is formally subjected to the strict, specialized banking system. Security underwriting and investment businesses are allowed in a very limited extent only for stocks and bonds of maturity longer than three year and only up to 100 percent of the bank paid-in capital. Until the end of 1991, the ceiling was only up to 25 percent of the total balance of the demand deposits. However, they are prohibited from the security brokerage business. While the in-house integration of security businesses with the traditional business of deposit and commercial lending is restrictively regulated as such, Korean banks can enter the security business by establishing subsidiaries in the industry. This paper, therefore, estimates the efficiency indicators as well as the cost functions, identifying the in-house integrated trust business and security investment business as important banking activities, for various cases where both the production and the intermediation function approaches in modelling the financial intermediaries are separately applied, and the banking businesses of deposit, lending and security investment as one group and the trust businesses as another group are separately and integrally analyzed. The estimation results of the efficiency indicators for various cases are summarized in Table 1 and Table 2. First, security businesses exhibit economies of scale but also economies of scope with traditional banking activities, which implies that in-house integration of the banking and security businesses may not be a nonoptimal banking structure. Therefore, this result further implies that the transformation of Korea's banking system from the current, specialized system to the universal banking system will not impede the improvement of the banking industry's efficiency. Second, the lending businesses turn out to be subjected to diseconomies of scale, while exhibiting unclear evidence for economies of scope. In sum, it implies potential efficiency gain of the continued in-house integration of the lending activity. Third, the continued integration of the trust businesses seems to contribute to improving the efficiency of the banking businesses, since the trust businesses exhibit economies of scope. Fourth, deposit services and fee-based activities, such as foreign exchange and credit card businesses, exhibit economies of scale but constant returns to scope, which implies, the possibility of separating those businesses from other banking and trust activities. The recent trend of the credit card business being operated separately from other banking activities by an independent identity in Korea as well as in the global banking market seems to be consistent with this finding. Then, how can the possibility of separating deposit services from the remaining activities be interpreted? If one insists a strict definition of commercial banking that is confined to deposit and commercial lending activities, separating the deposit service will suggest a resolution or a disappearance of banking, itself. Recently, however, there has been a suggestion that separating banks' deposit and lending activities by allowing a depository institution which specialize in deposit taking and investing deposit fund only in the safest securities such as government securities to administer the deposit activity will alleviate the risk of a bank run. This method, in turn, will help improve the safety of the payment system (Robert E. Litan, What should Banks Do? Washington, D.C., The Brookings Institution, 1987). In this context, the possibility of separating the deposit activity will imply that a new type of depository institution will arise naturally without contradicting the efficiency of the banking businesses, as the size of the banking market grows in the future. Moreover, it is also interesting to see additional evidences confirming this statement that deposit taking and security business are cost complementarity but deposit taking and lending businesses are cost substitute (see Table 2 for cost complementarity relationship in Korea's banking industry). Finally, it has been observed that the Korea's banking industry is lacking in the characteristics of natural monopoly. Therefore, it may not be optimal to encourage the merger and acquisition in the banking industry only for the purpose of improving the efficiency.

In proportion to the increase of public security demand, the private companies advanced continuously every year. However the size of the industry expanded in its quantity, the quality remains the same as before. So it's important to training of the security officers. This study suggest the improvements of training system through the analysis and the review of problems of training and education security officers. To develop our private security industry, we suggest as follows. First, In spite of the training is important, the recognition against security officers training is low, so the improvement is demanded. Second, When selecting the educational institution, it does not reflect the demand and situation of education enough. So there is necessary that selecting the educational institution again, after finishing a demonstration duration. Third, The education contents is general, so there is a necessity of the education which is professionalized. Fourth, In order to improve the ability of the lecturer, we must strengthen the qualification of the lecturer. Fifth, For the development of securities industry, we must found the professional training institution.

Financial conglomerates combine banking, securities, insurance and other financial services within a single economic entity. In this paper we analyze the effect of financial conglomeration on the default risk of financial companies in the Korean financial industry. We use two risk measures based on individual company level as proxies of the default risk, one is Z-index proposed by Altman(1968) and the other is the weighted capital adequacy ratio. We find that financial conglomeration has a negative effect on the default risk of financial companies. The asset size and diversity level of financial conglomerates, however, are negatively correlated with the default risk of financial companies. These results mean that in the Korean financial industry, even though the economy of scale and scope does exist, financial conglomeration does not translate into lower risk of financial companies composing financial conglomerates.

Purpose: The purpose of this study is to derive major policies that domestic small and medium-sized manufacturing companies should consider to maximize productivity and quality improvement by utilizing manufacturing data and AI, and to find priorities and implications. Methods: In this study, domestic and international issues and literature review by country were conducted to derive major considerations such as manufacturing AI technology, manufacturing AI talent, manufacturing AI data and manufacturing AI ecosystem. Additionally, the questionnaire survey targeting 46 experts of manufacturing data and AI industry were conducted. Finally, the major considerations and detailed factors importance were derived by applying the Analytic Hierarchy Process (AHP). Results: As a result of the study, it was found that 'manufacturing AI technology', 'manufacturing AI talent', 'manufacturing AI data', and 'manufacturing AI ecosystem' exist as key considerations for domestic manufacturing AI. After empirical analysis, the importance of the four key considerations was found to be 'manufacturing AI ecosystem (0.272)', 'manufacturing AI data (0.265)', 'manufacturing AI technology (0.233)', and 'manufacturing AI talent (0.230)'. The importance of the derived four viewpoints is maintained at a similar level. In addition, looking at the detailed variables with the highest importance for each of the four perspectives, 'Best Practice', 'manufacturing data quality management regime, 'manufacturing data collection infrastructure', and 'manufacturing AI manpower level of solution providers' were found. Conclusion: For the sustainable growth of the domestic manufacturing AI ecosystem, it should be possible to develop and promote manufacturing AI policies in a balanced way by considering all four derived viewpoints. This paper is expected to be used as an effective guideline when developing policies for upgrading manufacturing through domestic manufacturing data and AI in the future.

Japan came to result in enacting and enforcing the law on rationalization of service pertinent to the Private Detective Service Law in order to rationalize the illegal service realities of private detective service dealers and detective agencies, which were flooded in 2006. Since the enactment of the law, the problems are still taking place in relation to Japanese private detective service as of 2012. However, Japan's regulatory agencies can be known to revise the corresponding statute and to make effort to improve consciousness of agencies in order to improve these problems. Accordingly, it can be considered to be great in implication as for our country's introduction of private investigation service in the future. Arranging these contents, they are as follows. First, it is improvement in problems related to other statutes according to performance of private detective service. Second, it is reinforcement in management of private detective service violators. Third, it is propulsion of rationalization in cost according to a contract of private detective service. Accordingly, it can be considered to be necessary for being newly legislated at the 19th National Assembly from the perspective dubbed development and social right f unction in private investigation industry, by further supplementing Japan's these problems and arranging improvement plans so that the corresponding service called private detective service can do more public function in society.
