FinTech refers to a new type of financial service that combines finance and ICT technology, which is a combination of various financial services such as remittance, payment, loan, and asset management based on a wide range of users secured by global ICT companies or financial institutions. In the case of FinTech in Korea, simple payment services based on mobile devices is a big part of the FinTech service industry and researches are being actively carried out to widely activate to various fields. In addition, various policies for activating the FinTech industry, such as the abolition of the mandatory use of the certificate verification in June 2015, are in effect, and the mobile simple payment service is accordingly expected to be activated. Currently, as known through Paypal, Alipay, Transfer Wise, etc., in addition to simple payment using mobile devices only, various types of financial settlement services have been being provided. Moreover, government in each country has established various policies to foster the FinTech industry. The purpose of this study is to explain the concept and development background of FinTech, to analyze FinTech service and policy trends in Korea and abroad, and finally to propose problems and remedies of FinTech service in Korea.

South Korea has seven major shipbuilders out of world top ten global shipbuilders. The Major shipbuilding companies are Samsung, Hanjin, Hyundai, Daewoo, and STX. MTC International, Inc. is a provider of workforce solutions and services. It offers a range of services of recruiting, evaluation, training and development, labors management, and workforce consulting, to the companies mentioned above. Most of the experts in the industry forecasted that there would be a shortage of workers for the industry for the following several years. Therefore, this paper is aiming to enhance its competitiveness through the improving its revenues of MTC International, Inc. by providing with the foreign workers, especially from Philippines. Using SWOT Analysis, IE-Matrix with external and internal factor analysis, and SPACE matrix, those formulation tools suggest strategies for MTC International, Inc.

In the structure of ITO/N,N'-diphenyl-N,N' bis (3-methylphenyl)-1,1'-biphenyl-4,4'-diamine(TPD)/tris (8-hydroxyquinoline)aluminum($Alq_3$)/Al device, we studied the efficiency improvement of organic light-emitting diodes due to variation of deposition rate of hole transport layer (TPD) materials using hole-size of crucible boat. The thickness of TPD and $Alq_3$ was manufactured 40 nm, 60 nm, respectively under a base pressure of $5{\times}10^{-6}$ Torr using a thermal evaporation. The $Alq_3$ used for an electron-transport and emissive layer were evaporated to be at a deposition rate of $2.5\;{\AA}/s$. When the deposition rate of TPD increased from 1.5 to $3.0\;{\AA}/s$, we studied the efficiency improvement of TPD using the hole-size of crucible is 1.0 mm. When the deposition rate of TPD is $2.5\;{\AA}/s$, we found that the average roughness is rather smoother, the luminous efficiency the external quantum efficiency is superior to the others. Compared to the two from the devices made with the deposition rate of TPD is $2.0\;{\AA}/s$ and $3.0\;{\AA}/s$, the external quantum efficiency was improved by four-times and two-times, respectively.

In this Study, as the structure of IT module for smart phone display becomes thin to catch up with slim product trend, the reliability of display module is on the rise as a issue for product design. Especially, almost part of cellular phone should undergo thermal dissipation test. thus many manufacturers have considered design guide line using CAE and simulation for more effective usage of limited resources on the market. This test simulates the case when cellular phone slips through user’s fingers while he is talking on the phone. This paper studies a thermal simulation of display module in smart phone. This design for reliability improvements are suggested on the basis of the results of FVM Analysis and display of IT module and smart phone design.

In the device structure of ITO/tris(8-hydroxyquinoline) aluminum ($Alq_3$)/Al device, we investigated the efficiency improvement of organic light-emitting diodes (OLEDs) depending on the hole-size of crucible boat. The device was manufactured using a thermal evaporation under the base pressure of $5{\times}10^{-6}\;Torr$. The $Alq_3$ organics were evaporated to be 100 nm thick at a deposition rate of $1.5\AA/s$, and in order to investigate the optimal surface roughness of $Alq_3$, the $Alq_3$ was thermally evaporated to be 0.8 mm, 1.0 mm, and 1.5 mm as a hole-size of the boat, respectively. We found that luminance and external quantum efficiency are superior when the hole-size of the boat is 1.0 mm. The external quantum efficiency of the device made with the hole-size of 1.0 mm boat were improved by a factor of ten compared to the devices made with the hole-size of non boat.
