If additional condition in letter of credit is used in malicious way, it affects the international trade transaction in jeopardy. Therefore, it's significant to identify whether additional conditions are malicious or ordinary in the transaction with letter of credit. In normal cases, thanks to lots of useful features as an international payment method, such as security of payment, legal protection, and versatility, a letter of credit is widely used in international trade. However, even with these advantageous features, a letter of credit is complicate and costly to use, compared to other payment methods. Furthermore, due to its principle of independence from underlying contract, a use of letter of credit creates another type of concern for proper handling and needs significant caution upon field use. At some points, malicious additional conditions are used for buyer's advantage in deal making and fraud instance in worst situation. In addition, some countries request malicious conditions against sellers as a non-tariff barrier. Therefore it's extremely important to recognize whether malicious additional condition exists in letter of credit and, if so, how to deal with it. This study delivers the information to distinguish and categorize the malicious conditions in various cases and to figure out how to deal with them for safer trade with less risk.

On March 11, 2011, the Korea National Assembly finally passed the bill on the Damage Relief on the Medical Malpractice and Mediation for Medical Dispute. One of the features of this Act is including "The Subrogation Payment System for Damage (abbreviated SPSD)". This System is that 'Korean Medical Dispute Mediation-Arbitration Board' pays the damages, instead of the health care provider, for the patient who isn't paid damages by the health care provider despite of the Mediation or ruling. The purpose of this study is to search the problems and make improvement on SPSD. This System was introduced extreamly to the patients in order to induce them to the mediation. However,there remains several problems. In this articles, I have examined thoroughly the legal issues on SPSD. There are legal issues about the methods and ratio of the financial burden. In this connection, wide discretionary authority has been granted to administrative agencies specifically. On this account, this System clearly contains elements of a violation against the Constitutional Law. Moreover, this System can be broadly applied to the case of court ruling or the Korea Consumer Agency's mediation. But these measures go against the aim of legislation that the medical dispute can be resolved through the mediation or arbitration by this Act. In the end, these problems must be revised through the additional discussion.

A barcode is a representative means of cognition. It is either printed on the package of a product or attached to it as a sticker. It is used for the fast cognition of a product at a store. It is considerably cheap to make a barcode. Also, it is possible to read it fast by using a barcode reader. Because of such convenience provided by the barcode, a new system using the barcode as a means of settling payments like a currency or a credit card has been developed. However, due to its characteristics, it is easy to reduplicate, forge or falsify a barcode easily. Therefore, this study focuses on the case of applying the system using barcodes as a means of settling payments without providing solutions for the potential weaknesses. Also, this study suggests various points to consider regarding the creation of safe barcodes as one of the related measures, while providing various methods using additional means of certification other than the one of using barcodes in addition to the way of applying complexity with barcode numbers. Throughout this study, it will be possible to safely establish and operate the payment-settlement system using barcodes.

To understand the procedure of international commercial transaction clearly and logically, this author would like to emphasize the contractual approach in this paper. The main contract in the transaction is the contract of sale; to perform this contract, the three subordinate or supporting contracts(including the contract of carriage, the contracts of insurance and the contract of payment) should be followed and performed. In the contract of sale, besides the express Terms, the trade Terms have very comprehensive meanings. Each trade term in Incoterms(2000) deals with the matters relating to the rights and obligations of the parties to the contract of sale with respect to the delivery of the goods sold. It also provides for the duties of seller or buyer relating to the contract of carriage, the contract of insurance and the payment in the process of the delivery of goods. Especially, it does not provide the methods of payment concretely, but it imposes the seller to hand over the documents evidencing the conformity of the contract of sale, and the delivery which includes the documents of carriage and/or insurance. Thus although the trade Terms deal with the obligations of the seller or buyer directly, they are very closely related with the contract of carriage and the contract of insurance indirectly, and also with contract of payment using the documentary draft. For the Arbitration or the litigation in the case of the breach of contract, the trade Terms play very significant roles. When an arbitrator or a judge decides the case, they should understand each obligation clearly, in which case, the trade terms give answers about who is wrong or who is right. Therefore, the contractual approach focusing on the trade terms would give very fruitful advantages to the students or teachers in understanding the procedure of the international commercial transaction systematicly and comprehensively.

Objectives : To determine the impacts of Diagnosis-Related Groups/Prospective Payment System (DRG/PPS) on the quality of care in cases of Cesarean section and to describe the policy implications for the early stabilization of DRG/PPS in Korea. Methods : Data was collected from the medical records of 380 patients who had undergone Cesarean sections in 40 hospitals participating in the DRG/PPS Demonstration Program since 1999. Cesarean sections were peformed in 122 patients of the FFS(Fee-For-Service) group and 258 patients of the DRG/PPS group. Measurements of quality used included essential tests of pre- and post-operation, and the PPI(Physician Performance Index) score. The PPI was developed by two obstetricians. Results : Univariate analysis demonstrated significant differences in PPI scores according to the payment systems. With respect to the mean of PPI scores, a higher score was found in the DRG/PPS group than in the FFS group. However, the adjusted effect did not show significant differences between the FFS group and the DRG/PPS group. Conclusion : This study suggested that the problem of poor quality may not be related to the implementation of DRG/PPS in Cesarean section. However, this study did not consider the validity and reliability of the process measurement, and it did not exclude the possibility of data emission in medical records.

Purpose: The purpose of this study was to identify incidence of nonfatal unintentional injuries (accidents) among students, and to investigate compensation payment for five years (2000~2004) in schools located in Seoul. Methods: Subjects were 14,783 students injured among elementary, middle and high school students. The accumulated data for 5 years (2000~2004) was from the Seoul School Safety and Insurance Association. Chi-square, ttest, logistic regression, and MANCOVA were conducted. Results: The most frequent accidents occurred among males (73.2%), and in special school students (3.86 per 1,000) followed by middle school students (3.05 per 1,000), in May (0.25 per 1,000) followed by June and October, in physical education classes (0.73 per 1,000) followed by special activities (0.40 per 1,000), recess (0.31 per 1,000) and lunch (0.29 per 1,000). Fractures (0.86 per 1,000) were followed by mild injuries (0.39 per 1,000), joint and ligament injuries (0.31 per 1,000), and teeth injuries (0.26 per 1,000). After adjusting for potential confounding variables, the highest means of final compensation payment was for burns (810 thousand KRW) followed by the teeth injuries (506 thousand KRW), cleaning injuries (550 thousand KRW) followed by injuries incurred during special activities (510 thousand KRW) and injuries incurred at special schools (556 thousand KRW). Conclusion: In school, the highest incidences of nonfatal unintentional injuries were in special schools, among males, fractures and physical education. However, the highest compensation payments were for burns, and injuries taking place at special schools and during cleaning hour. Proper health education including teaching healthy habits for safety/injury prevention is needed to prevent injuries and decrease compensation.

With the diversification of payment methods and games, related financial accidents are causing serious problems for users and game companies. Recently, game companies have introduced an Fraud Detection System (FDS) for game payment systems to prevent financial incident. However, FDS is ineffective and cannot provide major evidence based on judgment results, as it requires constant change of detection patterns. In this paper, we analyze abnormal transactions among payment log data of real game companies to generate related features. One of the unsupervised learning models, Autoencoder, was used to build a model to detect abnormal transactions, which resulted in over 85% accuracy. Using X-FDS (Explainable FDS) with XAI-SHAP, we could understand that the variables with the highest explanation for anomaly detection were the amount of transaction, transaction medium, and the age of users. Based on X-FDS, we derive an improved detection model with an accuracy of 94% was finally derived by fine-tuning the importance of features that adversely affect the proposed model.

The outbreak of the COVID-19 pandemic has had a significant impact on the Vietnamese economy. In the midst of a complex disease that compelled people to limit their interaction, customers' shopping habits shifted from "offline" to "online" transactions. Mobile payments have also grown in popularity. The goal of this study is to figure out what factors influence the use of mobile payments by hotel clients in Can Tho after COVID-19. The research team also examines how those factors influence customers' willingness to use mobile payment and makes recommendations to better the current situation. Primary data was collected from 227 persons using online surveys and processed with SPSS software for this study. To analyze the correlation relationship between the elements determining the intention to use, the Cronbach alpha, EFA, Correlation, and Regression methods used to assess the scale are applied. Perceived Trustworthiness, Perceived Usefulness, and Perceived Ease of Use all have positive effects on customers' propensity to use, according to the findings. Perceived Security, on the other hand, has no bearing. The findings of this study have significant theoretical and practical implications for the development of mobile payment services in Can Tho, particularly following the implementation of COVID-19.

Objective: The Australian Pharmaceutical Benefits Scheme (PBS) is a national drug subsidy program. Given the similarity and comprehensiveness of the Australian PBS and the Korean National Health Insurance (NHI) data, these data are increasingly used for pharmacoepidemiological investigations, as well as international comparative studies. This study aims to introduce the various sources of publicly available PBS data and provide a practical guide to researchers conducting drug utilization studies. Methods: We searched literature and websites to detail and compare the collection, structure, components, and characteristics of each PBS data format. We identified different characteristics of the PBS data from the Korean NHI claims data which are mainly owing to their unique co-payment policies and data collection processes. In addition, the utilization and expenditure of atorvastatin, a widely used treatment for hyperlipidemia, were analyzed using two different sources of PBS data and the different results were interpreted. Results: There exist differences in when data were collected or non-subsidized uses of medicine were included among sources of PBS data. Additionally, two countries have different cost sharing methods inmedicine subsidy scheme; co-payment in Australia and co-insurance in Korea. Therefore, it should be noted that prescriptions under co-payment are not included in some data sources in Australia. Conclusion: Despite several analytical challenges, open access and easy data management are the strengths of the PBS data sources. A detailed knowledge of the PBS data can ensure robust methodology and interpretation of pharmacoepidemiological investigations or international comparative studies.
