This study examines the effects of CBDC(Central Bank Digital Currency) on the Korean economy in the digital currency era and discusses the response strategies for CBDC. With the review of the definition and the development status of digital currency, we explore the characteristics and current status of CBDC in Korea as well as the possibility for internationalization of CBDC. The result shows that CBDC can reduce credit risk, improve transaction transparency compared to cash, and increases monetary policy capacity. Meanwhile, the credit and intermediary function of financial institutions may be weakened, and side effects such as financial alienation may occur. Nevertheless, as the issuance of CBDC is an important opportunity to enhance the possibility of internationalization of Korean Won, preemptive measures are required to keep pace with the competition and cooperation with each country toward the digital key currency. We need to accelerate the digital financial environment through Korea's comparative advantage, and develop a strategy to achieve the internationalization of the financial industry and the Korean Won through CBDC issuance. From the early stage of CBDC designing, it is necessary to achieve international agreements through cooperation with other central banks and to develop policies suitable for the transition to digital currency.

As international transactions have grown more numerous, situations of disputes related to the transactions are getting more complicated and more diverse. Cost-effective remedies to settle the disputes through traditional methods such as adjudications of a court will be insufficient. There fore, nations are attempting to more efficiently solve investor-state disputes through arbitration under organizations such as the ICSID Convention, the ICSID Additionary Facility Rules, and the UNCITRAL Arbitration Rules by including the provisions on investor-state dispute settlement at the conclusion of an investment agreement. In case of an arbitration under the ICSID Convention, ICSID directly exercises the supervisorial function on arbitral proceedings, and there is no room for the intervention of national courts. In time of the arbitration where the ICSID Convention does not apply, however, the courts have to facilitate the arbitral proceedings. When the recognition and enforcement of an arbitral award under the ICSID Convention are guaranteed by the Convention, it should be considered that the New York Convention does not apply to them under the Convention Article 7 (1) fore-end. In exceptional cases in which an arbitral award under the ICSID Convention cannot be recognized or enforced by the Convention, the New York Convention applies to the recognition and enforcement because the award is not a domestic award of the country in which the recognition or enforcement is sought. It is up to an interpretation of the New York Convention whether the New York Convention applies to ISDS arbitral awards not based on the ICSID Convention or not. Although an act of the host country is about sovereign activities, a host country and the country an investor is in concurring to the investment agreement with the ISDS provisions is considered a surrender of sovereignty immunity, and it will not suffice to exclude the investment disputes from the scope of application of the New York Convention. If the party to the investment agreement has declared commercial reservation at its accession into the New York Convention, it should be viewed that the Convention applies to the recognition and enforcement of the ISDS awards to settle the disputes over an investitive act, inasmuch as the act will be considered as a commercial transaction. When the recognition and enforcement of an arbitral award on investment disputes about a nation's sovereign act have been sought in Korea and Korea has been designated the place of the investment agreement arbitration as a third country, it should be reviewed whether the disputes receive arbitrability under the Korean Arbitration Act or not.

The study participants are nurses who work at three general hospitals in M City, who used structured questionnaires to list 214 people from July 17 to August 7, 2017. Analysis of the collected data was carried out using SPSS WIN 21.0. and M plus 7.00 to analyze latent classes depending on the type of nursing managers' leadership. This study showed that the type of nursing managers' leadership has in analyzing latent classes influences nurses' job performance and turnover intention. Because there is a strong influence on the job performance and the turnover intention so that nurses can be highly aware of transformation-transaction-emotion leadership, the managers of the nursing organization need to foster effective leadership. Training programs are needed to improve nurses' job performance through transformational, transactional, and emotional leadership, and to foster nursing manager's leadership skills to better reflect the turnover intention.

The study attempts to consider L/G(Letter of Guarantee) in a different angle, which is internationally used as a way of commercial customs and practices in a case when the consignee wants to receive the goods without the original Bill of Lading, Thus, this study focuses more on verifying the usage of L/G in Mixed Payment System and the range of guarantee responsibility by an issuing bank through case analysis. This case uses a mixed payment method of L/C(Letter of Credit) and T/T(Telegraphic Transfer) in the transaction of goods. The issuing bank of L/C issues L/G with the amount of L/C which is the same as the amount as C/I(Commercial Invoice). However the carrier deliver all goods laden under both L/C and T/T payment with the production of L/G. In this case, because the buyer is unable to pay, the seller makes a claim for damages to the carrier that the carrier delivers the goods to the buyer against L/G. Finally, the judge gives a decision that the issuing bank of L/G should pay the whole amount of the goods. In this case, the main issue of the dispute is the range of guarantee responsibility by the issuing bank of L/G. As a result of the case analysis, the study suggests two counter strategies for smooth utilization in international trade environment. First, in the case of mixed payment system, a seller should issue a commercial invoice separately based on the amount of each settlement plan in order to clarify the liability of guarantee. Second, banks should establish a new form for L/G including a sentence for verifying liabilities of the bank's side in the current form of L/G.

Amidst the acceleration of digital transformation across various sectors, the financial market is increasingly focusing on the development of digital and electronic payment methods, including currency. Among these, Central Bank Digital Currencies (CBDC) are emerging as future digital currencies that could replace physical cash. They are stable, not subject to value fluctuation, and can be exchanged one-to-one with existing physical currencies. Recently, both domestic and international efforts are underway in researching and developing CBDCs. However, current CBDC systems face scalability issues such as delays in processing large transactions, response times, and network congestion. To build a universal CBDC system, it is crucial to resolve these scalability issues, including the low throughput and network overload problems inherent in existing blockchain technologies. Therefore, this study proposes a solution based on reinforcement learning for handling large-scale data in a CBDC environment, aiming to improve throughput and reduce network congestion. The proposed technology can increase throughput by more than 64 times and reduce network congestion by over 20% compared to existing systems.

Commerce enriches human life enriched and within commerce, transportation of cargo is arguably the most important in business transactions. Traditionally, marine transport has been major commercial transaction, but carriage cargo by air is on the increase. While the fare for freight in comparison with that of ocean is higher, air freight has many benefits that justify the higher shipping fee; lower insurance premium, packing charges, inventory control, cost management and especially speed. Therefore, air freight transport is accumulating gradually. An air waybill(AWB) is needed in the air transport flow. It is a nonnegotiable security, so the holder cannot transfer of a right to a third party. Some scholars suggest that a negotiable AWB is needed. However, it seems nearly impossible to do so; an e-AWB use shows a gain in numbers, even if it has not met expectations. Going forward, it would appear reasonable to conduct a follow-up study on the utility and legal problem for e-AWB. After sending goods, the consignor has the right of disposition of cargo in some cases, and more research is necessary, because it is related to change of ownership and a trade settlement. According to WATS (World Airlines Transport Statistics), the Korean Air took third place in international freight in 2014, and fifth in total, domestic and international to great acclaim. However, there is a lack of research supporting the business showing. It is hope that more studies on e-AWB, stoppage in transit, and a risk of outstanding amount, etc. connect to develop Korean air freight industry.

The seller and the buyer write down the agreed details in the trade contract as trade contract clauses. In the case where a letter of credit is agreed to be the payment condition, the buyer shall open a letter of credit to the seller with the shipping date specified in the trade contract through its bank. In this case, the legal relationship between the performance date of the trade contract and the shipment date of the letter of credit, the change of the performance date of the trade contract due to the change of the trade contract and the change of the shipment date specified in the letter of credit, the seller's letter of credit A problem arises in the legal interpretation of the approval period and the change request period. Therefore, this paper analyzed the precedents of the Seongnam Branch of the Suwon District Court and the Seoul High Court related to these legal issues. The performance date of a trade contract is the seller's delivery date and the buyer's payment date. In the letter of credit transaction, the date of performance of the trade contract is regarded as the date of shipment and the date of negotiation of documents specified in the letter of credit. The seller must decide whether to accept the letter of credit within 5 banking days after receiving the letter of credit from the buyer. After this period has elapsed, the seller cannot refuse the letter of credit. However, if the buyer is unable to decide whether to accept the letter of credit within 5 banking days due to reasons attributable to the buyer, the delivery date specified in the letter of credit will be extended. If the seller requests an amendment to the letter of credit, the buyer must accept it and open the letter of credit the seller desires to the seller. If the buyer refuses the seller's request to change the letter of credit, company A has the obligation to change and reopen the letter of credit as requested by company B. Expect by agreeing on the quotation As it is a fundamental breach of contract stipulated in Article 25 of the United Nations Convention on Contracts for the International Sale of Goods, company B can cancel the trade contract and claim damages from company A. Compensation for damages caused by Company A's breach of the trade contract shall be an amount equal to the loss suffered by Company B as a result of the breach, including loss of profits.

The meaning of Online ADR lies in the prompt and economical resolution of disputes by applying the information/communication element (Internet) to existing ADR. However, if the promptness and economical efficiency are overemphasized, the fairness and appropriateness of dispute resolution may be compromised and consequently Online ADR will be belittled and criticized as second-class trials. In addition, as communication is mostly made using texts in Online ADR it is difficult to investigate cases and to create atmosphere and induce dynamic feelings, which are possible in the process of dispute resolution through face-to-face contact. Despite such difficulties, Online ADR is expanding its area not only in online but also in offline due to its advantages such as promptness, low expenses and improved resolution methods, and is expected to develop rapidly as the electronic government decided to adopt it in the future. Accordingly, the following points must be focused on for the continuous First, in the legal and institutional aspects for the development of Online ADR, it is necessary to establish a framework law on ADR. A framework law on ADR comprehending existing mediation and arbitration should be established and it must include contents of Online ADR, which utilizes electronic communication means. However, it is too early to establish a separate law for Online ADR because Online ADR must develop based on the theoretical system of ADR. Second, although Online ADR is expanding rapidly, it may take time to be settled as a tool of dispute resolution. As discussed earlier, additionally, if the amount of money in dispute is large or the dispute is complicated, Online ADR may have a negative effect on the resolution of the dispute. Thus, it is necessary to apply Online ADR to trifle cases or domestic cases in the early stage, accumulating experiences and correcting errors. Moreover, in order to settle numerous disputes effectively, Online ADR cases should be analyzed systematically and cases should be classified by type so that similar disputes may be settled automatically. What is more, these requirements should reflected in developing Online ADR system. Third, the application of Online ADR is being expanded to consumer disputes, domain name disputes, commercial disputes, legal disputes, etc., millions of cases are settled through Online ADR, and 115 Online ADR sites are in operation throughout the world. Thus Online ADR requires not temporary but continuous attention, and mediators and arbitrators participating in Online ADR should be more intensively educated on negotiation and information technologies. In particular, government-led research projects should be promoted to establish Online ADR model and these projects should be supported by comprehensive researches on mediation, arbitration and Online ADR. Fourth, what is most important in the continuous development and expansion of Online ADR is to secure confidence in Online ADR and advertise Online ADR to users. For this, incentives and rewards should be given to specialists such as lawyers when they participate in Online ADR as mediators and arbitrators in order to improve their expertise. What is more, from the early stage, the government and public institutions should have initiative in promoting Online ADR so that parties involved in disputes recognize the substantial contribution of Online ADR to dispute resolution. Lastly, dispute resolution through Online ADR is performed by organizations such as Korea Institute for Electronic Commerce and Korea Consumer Protection Board and partially by Korean Commercial Arbitration Board. Online ADR is expected to expand its area to commercial disputes in offline in the future. In response to this, Korean Commercial Arbitration Board, which is an organization for commercial dispute resolution, needs to be restructured.

Purpose of study: Lingual nerve damage can be caused by surgery or trauma such as physical irriatation, radiation, chemotherapy, infection and viral infection. Once nerve damage occurred, patients sometimes complain taste change and loss of taste along with serious disturbance of tongue. The purpose of this study was to evaluate the effects of unilateral lingual nerve transection on taste as well as on the maintenance of taste buds. Materials & Methods: Male Sprague-Dawley rats weighing 220-250g received unilateral transection of lingual nerve, subjected to the preference test for various taste solutions (0.1M NaCl, 0.1M sucrose, 0.01M QHCl, or 0.01M HCl) with two bottle test paradigm at 2, 4, 6, or 8 weeks after the operation. Tongue was fixed with 8% paraformaldehyde. After fixation, they were observed with scanning electron microscope(JSM-$840A^{(R)}$, JEOL, JAPAN) and counted the number of the dorsal surface of the fungiform papilla for changes of fungiform papilla. And, Fungiform papilla were obtained from coronal sections of the anterior tongue(cryosection). After cryosection, immunostaining with $G{\alpha}gust$(I-20)(Santa Cruz Biotechnology, USA), $PLC{\beta}2$(Q-15)(Santa Cruz Biotechnology, USA), and $T_1R_1$(Alpha Diagnostic International, USA) were done. Immunofluorescence of labeled taste bud cells was examined by confocal microscopy(F92-$300^{(R)}$, Olympus, JAPAN). Results: The preference score for salty and sweet tended to be higher in the operated rats with statistical significance, compared to the sham rats. Fungiform papilla counting were decreased after lingual nerve transaction. In 2 weeks, maximum differences occurred. Gustducin and $T_1R_1$ expressions of taste receptor in 2 and 4 weeks were decreased. $PLC{\beta}2$ were not expressed in both experimental and control group. Conclusion: This study demonstrated that the taste recognition for sweet and salty taste changed by week 2 and 4 after unilateral lingual nerve transection. However, regeneration related taste was occurred in the presence of preserving mesoneurial tissue and the time was 6 weeks. Our results demonstrated that unilateral lingual nerve damage caused morphological and numerical change of fungiform papilla. It should be noted in our study that lingual nerve transection resulted in not only morphological and numerical change but also functional change of fungiform papillae.
