South Korea, despite the financial turbulences has marked the trade volume of USD 1 trillion and marked $7^{th}$ largest exporter in 2013. Approximately 40% of the entire import of Korea was for export. In the South Korean trade structure, import and export are closely related, requiring proactive import financial assistance policies. Recognizing this, K-sure has made import insurance policy available on the market since July 2010. The K-sure insurance policy targets both financial institutions and importers. This is the reason why this research seeks to review the import insurance terms for importers and compare with foreign import insurance products to find out ways to improve. K-sure's import insurance for importers is to cover a loss of a policyholder when the policyholder or importer domestically addressed made a prepayment but cannot receive goods. The import insurance is applied to import transactions of goods or resources. K-sure's import insurance coverage needs to be expanded to intermediary trade and consignment processing trade, etc. In this sense, a more systematic educational program should be introduced about K-sure's import insurance.

Because the damages of corrosion resulting from the chloride ion are very serious, many research studies have been performed to measure the penetration depth of the chloride ion. However, there is a problem with data selection obtained from collection during experiments. In this study, it appears that the collected data are not conformed to a normal distribution. The result of this study will play a very important role, as a first step for the development and construction of a forecasting system to help determine a reliable service lifetime of marine structures.

The purpose of this paper was to take an in-depth look at early American English around the $17^{th}$ and $18^{th}$ century when immigrants from different European countries started to move into the New World. The paper attempted to describe early American English in relation to the process of immigration and settlement from a historical perspective. With a focus on major features of early American English such as uniformity, archaism and richness of lexicon, the paper tried to answer the questions such as how settlement influenced the formation and distribution of regional dialects across the continent, why immigrants tended to show a preference for a uniform way of speaking rather than choosing a variety of regional dialects for communication, and what role foreign languages played in the development of early American English. The overall findings based on the answers to these questions showed how American English went through a variety of processes and changes at the early stages of its development to become a national language later. The paper concluded with some remarks about the implications of the findings for EFL learning and the direction of future research on early American English.

Recently, printing and coating technologies application fields have been expanded to the energy field such as solar cell. One of the main reasons, why many researchers have been interested in printing technology as a manufacturing method, is the reduction of manufacturing cost. In this paper, We fabricated CIGS solar cell thin film layer by doctor blade methods using synthesis of CIS precursor nanoparticles ink on molybdenum (Mo) coated soda-lime glass substrate. Synthesis CIS precursor nanoparticles ink fabrication was mixed Cu, In, Se powder and Ethylenediamine, using microwave and centrifuging. Using multi coating process as we could easily fabrication a fine flatness CIS thin-film layer ($0.7{\sim}1.35{\mu}m$), and reduce a manufacture cost and process steps. Also if we use printing and coating method and solution process in each layer of CIGS solar cell (electrode, buffer), it is possible to fabricate all printed thin-film solar cell.

A classic examples of the abnormal combustions are the knock and misfire, which raise noxious performance and life of the engine. A heavy knock can also cause severe damages to the engine itself, which gives more reason why it must be detected and corrected. With the response of the today's requirements, we have researched the new diagnostic system which uses the breakdown voltage characteristics between electrodes of spark plug. This breakdown voltage depends on the pressure, temperature and even the shape and material of electrodes. But there is no data of breakdown voltage in case of using the spark plug as a electrodes. So, in this study, we show the breakdown voltage characteristic by pressure and temperature in constant volume bomb, which will make it possible to diagnose the engine combustion phenomenon.

This paper discusses why Korean speakers have problems in pronouncing some medial sonorant clusters in English. We argue that the main reasons lie in the sonority sequence requirement difference between the two languages. English does not have any specific sonority sequence preference between the medial sonorant sequences while Korean has a strict requirement between the two sonorants over a syllable boundary. This sonority sequence requirement difference between the two languages acts as an interference for Korean speakers in learning English pronunciation. This barrier for Korean speakers in acquiring correct pronunciation is implemented in a constraint ranking difference in the Optimality Theory, which is not familiar for Korean speakers. Understanding the details of sonorant production mechanisms along with the different constraint ranking will facilitate the learning process of Korean speakers learning English.

There are many reasons why foreigners have difficulties learning English. In addition to the difference between English and the learner's grammar, the large number of irregularities found in English become another obstacle to learning English. Understanding the difference and the irregularities will help us not only have a good command of English but also teach English more effectively. Many irregular or alternating patterns, or even anomalies in Modern English are the results of historical changes. In this paper, I would like to focus on some of the irregular or alternating patterns found in different components of the grammar of English and to show how they can be accounted for historically. Through this study, I would like to show that the irregular patterns and anomalies in English were once regular and systematic, they have deviated from the regular patterns of the grammar as time has gone by, and they have survived in Modern English as irregular and alternating patterns. Many of the irregular or alternating patterns can be traced back by phonological, morphological and/or semantic changes in the history of English. Finally, by looking at language history, we can hold a more tolerant view on many anomalies present in English.

CEMTool is a command style design and analyzing package for scientific and technological algorithm and a matrix based computation language. In this paper, we present a compiler based approach to the implementation of the command mode generalized PDE solver in CEMTool. In contrast to the existing MATLAB PDE Toolbox, our proposed FEM package can deal with the combination of the reserved words such as "laplace" and "convect". Also, we can assign the border lines and the boundary conditions in a very easy way. With the introduction of the lexical analyzer and the parser, our FEM toolbox can handle the general boundary condition and the various PDEs represented by the combination of equations. That is why we need not classify PDE as elliptic, hyperbolic, parabolic equations. Consequently, with our new FEM toolbox, we can overcome some disadvantages of the existing MATLAB PDE Toolbox.

In this paper, a smartphone-controlled personal mobility system (PMS) with semi-autonomous navigation is developed. The proposed PMS moves to waypoints and then reaches the destination where the waypoints and destination are selected by the user using Google maps in a smartphone. The hardware environment consists of a GPS (Global Positioning System) in the smartphone and a compass sensor. In addtion, while it is moving in autonomous mode, the user can intervene and change the direction and speed of the PMS in order to avoid obstacles that may be encountered accidentally in a dynamic environment. That is why it is called "semi-autonomous navigation". Experimental results showed that the proposed PMS is effectively able to migrate to the waypoints and destination in both autonomous and manual modes.
