Korean small and medium sized software companies have tried to export their solutions or services to overseas markets. In 2016, exports of the software industry increased by 6.0% from the previous year, and the value added of the industry was 2.2 times higher than that of the manufacturing industry. From a long-term perspective, it is important to secure a global competitive advantage in order to sustain the export high value-added of the software industry. The obstacles to entry into the overseas market of small to medium enterprises are as follows: first, difficulty in product development and localization of marketing; second, lack of investment for overseas expansion; and finally, competitiveness of software technology. In particular, To overcome such obstacles, Korean small and medium sized software companies should increase the technical perfection and secure software export competitiveness. The paper presents a payment settlement framework enabling adaptive reuse and semiautomatic development of global payment settlement services. The quantitative and qualitative evaluation results are presented with domestic and overseas case studies as follows: Firstly, semi-automatic development is realized successfully by applying the framework. Secondly, it is possible to maintain consistent quality of software and to deliver maintenance services without relying on the internal human resources. Thirdly, it is possible to reduce the project duration of the same development cope to less than 50% by applying the framework. Finally, because it is based on BPMN 2.0, which is a high level design diagram, it is expected that it will be easy to implement through components connection and reduce difficulties in technology transfer and localization. Also, at the time of runtime operation, it will be effective to understand the design idea easily and to carry out additional developments without human resource who participated in the initial project.

We analyzed the relationship between small- and medium-sized corporate bank loans and bank's equity ratio, as well as small- and medium-sized corporate bank loans and bank's performance in Korean banking industry. Using the data from the Bank of Korea and the Financial Supervisory Service, we made a panel data set, including small and medium corporate loan ratio, BIS ration, basic equity ratio, performance ratio, etc. We found a positively significant relationship between small- and medium-sized corporate loans and bank's equity ratio. There was a positive change of this relationship between the pre-financial crisis and post-financial crisis periods. In the post-financial crisis period, small- and medium-sized corporate bank loans had a significantly positive impact on the bank's equity ratio and bank's performance. We expect that these results will give new insights and contribute to the already-existing knowledge as well as to the Korean government institutions that are interested in the impact of small- and medium-sized corporate bank loans.

The goal of this study is to investigate and provide information to the Fintech Industry on the main factors responsible for customer loyalty via the mediating effect of customer satisfaction. Secondly, providing traditional banking reasons for customer shifts from banking to Fintech, therefore these factors could be more focused. The consumer choices presented in this study can thus serve as a foundation for further research into post-adoption behaviors associated with Fintech for cross-border payments. This study examines consumer evaluations of how key attributes of fintech using mobile payment services affect their choice by using a conjoint analysis approach, which allows for the approximation of user preferences for specific features. In our study we have used SPSS 26 to test the reliability and mediation effect on the sample size of 348 people who regularly used Fintech for cross border payments. All the questionnaires were prepared if the customers were given fintech as an option instead of traditional banks to send their remittances abroad. The result shows that(Service Quality, Customer's trust and product quality) effecting customer satisfaction significantly would be very helpful for the current fintechs working for home remittances to improve these factors and would serve as a benchmark for the upcoming fintech startups and traditional banks to focus on these factors and catch up the fintech Industry. Finally, it is argued that, in order to be successful, focusing on service quality, customer trust, and product quality triggered customer loyalty for the Fintech in comparison to other traditional options for cross-border payments via the mediation effect of customer satisfaction.

This new publication added the word "official" in the title. In order to being an official commentary, the terms and expression should be correct and unified. But there is some problems in official commentary and legal phraseology. The problem was appeared that ICC UCP 600's were translated into Korean UCP 600 version. For example, "Issuing Bank", "Applicant", "Port of discharge", "A date of pick-up", "Shipper's load and count", "Courier Receipt", "Charter Party", "Bill of Lading", "Cover Note", "Exclusion Clause", "Insurance Certificate", "Declaration, Underwriter". If can be used 'Official Commentary on UCP 600', the above statements should be a compliment though take a wide professional opinions or held a public hearings. The Purpose of this paper is to point out the problems and substitute the term used and unify the expression in official commentary.

Evaluation of the methods of processing allogenic bone must be considered in order to make an effective choice of graft materials in oral surgery. Allograft materials processed by the tissue banking industry have varying capacities of bone reconstruction. The biological function of processed bone can be affected by many factors, like particle size, processing parameters, and inclusion or exclusion of mineral and moisture. For example, freeze drying step offers a safe and economical means for packaging, shipping, storage, and preservation of homologous bone. Demineralization of cortical bone using hydrochloric acid can produce a uniform demineralized surface with a capacity for osteoinduction. The objectives of this review were to evaluate the processing methods for allogenic bone and to characterize processed materials for grafting. It is important to understand the biological, biomechanical healing of different types of allografts to make the right choice for allogenic bone on each clinical application and to achieve a successful outcome for alveolar bone reconstruction in oral surgery.

Recently, the export claims related to the compliance of the commercial invoice are increasing. This paper aims to review the basic requirements of the invoice, and two theories on the document compliance, i.e., the strict compliance and the substantial compliance, and to analyse the substantial compliance of the invoice through some recent cases under the UCP 500, ICC's opinions and the International Standard Banking Practice (ISBP). As regards the compliance of the invoice, a majority of the cases has held that it must comply strictly with the credit terms ("strict compliance rule"). However, a minority of courts and credit industry standards such as the UCP and ISBP published by ICC take a different approach, infusing the credit law notions such as equity, "substantial compliance rule", etc. The extent of the substantial compliance of the invoice is particularly explained in the above-mentioned invoice paragraphs of the ISBP and supported by a large number of ICC's official opinions. Especially, the parties and descriptions in the invoice must correspond with those in the credit, being not inconsistent with the other documents. Other issues related to invoices such as a tolerance of the quantity, the amount, and the number of originals or copies, etc. must comply with the credit terms substantially.
