In ancient times, respiration's perceived purpose was only to cool the blood, and nasal mucus was thought to be a discharge from the brain. Later it was demonstrated that fluids cannot travel from the brain to the nose. It appears that credit for pointing out the medical significance of bronchial secretions and the biological value of the exocrine function of the lungs belongs to Laennec. He described the “chronic idiopathic pituitous catarrh” known today as bronchorrhea, which is characterized by paroxysms of expectoration. The importance of all this is that airway secretions, and their alterations, became one of the cardinal signs of many respiratory diseases (1).

This study was intended to identify customer's response to CRM of fashion business.488 questionnaires were distributed to male and female respondents aged 16 to 55, and then analyzed by descriptive statistics, oneway-ANOVA, chi-square test, and factor analysis. As a result of customer information management, respondents evaluated taste, interest and demographic informations as most valuable. But they did not value personal and credit information. For CRM concept, 4 factors were determined: continuous care and suggestion, particular service to important customer, customer management program development, and customer convenience consideration. For CRM activity, 3 factors were determined: customization, information offering, and programmed service strategies. Respondents were having positive attitude toward CRM concept and activity of fashion business. Among customer loyalty programs, they affected by immediate and direct programs most. The preference of customer contact methods was differentiated by sex and age groups. Males and teenagers preferred e-mail, and females preferred catalog and telephone connection.

Wireless Sensor Networks have been proposed for several location-dependent applications. For such systems, the cost and limitations of the hardware on sensing nodes prevent the use of range-based localization schemes that depend on absolute point to point distance estimates. Because coarse accuracy is sufficient for most sensor network applications, solutions in range-free localization are being pursued as a cost-effective alternative to more expensive range-based approaches. In this paper, we proposed a Coefficient Allocated DV-Hop (CA DV-Hop) algorithm which reduces node's location error by awarding a credit value with respect to number of hops of each anchor to an unknown node. Simulation results have verified the high estimation accuracy with our approach which outperforms the classical DV-Hop.

Bankruptcy is a significant risk for start-up companies, but with the help of cutting-edge artificial intelligence technology, we can now predict bankruptcy with detailed explanations. In this paper, we implemented the Category Boosting algorithm following data cleaning and editing using OpenRefine. We further explained our model using the Shapash library, incorporating domain knowledge. By leveraging the 5C's credit domain knowledge, financial analysts in banks or investors can utilize the detailed results provided by our model to enhance their decision-making processes, even without extensive knowledge about AI. This empowers investors to identify potential bankruptcy risks in their business models, enabling them to make necessary improvements or reconsider their ventures before proceeding. As a result, our model serves as a "glass-box" model, allowing end-users to understand which specific financial indicators contribute to the prediction of bankruptcy. This transparency enhances trust and provides valuable insights for decision-makers in mitigating bankruptcy risks.

The air waybill is supposed to be made out by the consignor. If the carrier makes it out, he is deemed, subject to proof to the contrary, to have done so on behalf of the consignor. The air waybill shall be made out in three original parts. The first part shall be marked "for the carrier", and shall be signed by the consignor. The second part shall be marked "for the consignee", it shall be signed by the consignor and by the carrier and shall accompany the goods. The third part shall be signed by the carrier and handed by him to the consignor, after the goods have been accepted. According to the original Warsow Convention article 8, the air waybill must contain 17 particulars or items. However, the Hague Protocol reduced to three the number of particulars required to appear on the air waybill. Only one item is obligatory, namely, the notice that the carriage is subject to the rules of the Warsaw Convention. The absence of the air waybill entails unlimited liability of the carrier because it deprives him of the right to avail himself of the provisions of the Warsaw Convention which exclude or limit his liability. The consignor shall be liable for all damages suffered by the carrier or any other person by reason of the irregularity, incorrectness or incompleteness of the particulars and statements in the air waybill. Although the contract of the carriage of goods by air is not a formal contract, the document of carriage is issued. The issue of air wayhill is not essential for the existence or validity of the contract, but serves merely as a means of proof. The Hague Protocol has lessened the consequences of the carrier's neglect to faithfully accomplish the required formalities. Henceforth, these formalities no longer constitute legal obligations. The air waybill is the consignment note used for the carriage of goods by air. It is often called an air consignment note and is not a document of title or transferable/negotiable instrument. It is basically a receipt for the goods for despatch and is prima facie evidence of the conditions of carriage. Each of the original parts of the air waybill has evidential value and possession of his part is a condition for the exercise by the consignor or cosignee of his rights under the contract of carriage. Oveall, it is an usage that under a documentary letter of credit, the consignee on the air waybill is the opening bank of the letter of credit, and the notify party is the importer who applied for the letter of credit. In Korea there is an usage as to process of cargo delivery in air transportation as follows: The carrier carries the cargo into the bonded area of the airport and gives both the notice of arrival of the cargo and the consignee's air waybill to the notify party who is the importer. Then the notify party obtains the Letter of Guarantee from the opening bank in exchange for reimbursing the amount of the letter of credit or tendering the security therefor to the opening bank. The notify party then presents this document to the customs authorities for the process of customs clearance. The opening bank becomes a consignee only to ensure repayment of the funds it has expended, and the only interest of the opening bank as consignee is the reimbursement of the money paid to the exporter under the documentary letter of credit. Just as the bill of lading in maritime law, the air waybill has always been considered negotiable although the Warsaw Convention does not emphasize this aspect of negotiability. However, the Hague Protocol article 4 corrected the situation by stating that "nothing in this Convention prevents the issue of a negotiable air waybill." This provision officially recognizes that the air waybill must meet the needs of the present day business circles by being a negotiable instrument. Meanwhile, Montreal Additional Protocol no. 4 has brought important changes. Registration by computer is acceptable and the parties to the contract of carriage are allowed to replace the air waybill with a receipt for the goods. In conclusion, as the Warsaw Convention has not details of provisions relating to the issuing of the negotiable air waybill, it is hoped that there should be supplement to the Warsaw Convention and establishment of international commercial usage with regard to the negotiable air waybill.

Available evidence suggests that the average marginal propensity to consume (MPC) from the 2001 tax rebate in the US was not nearly as large as that from previous tax cuts. We examine if this phenomenon can be explained by the fact that the widespread use of credit cards has made borrowing accessible for most US households by constructing a model that simulates the dynamic effect of relaxed borrowing constraints. Our model uses Kreps-Porteus preferences which account for independent measures of relative risk aversion and the elasticity of intertemporal substitution, both of which can theoretically affect the willingness to save or spend. Our model shows that the average MPC drops substantially immediately after borrowing constraints are relaxed because few consumers have binding borrowing constraints at that time. The model also shows that consumers gradually reduce their wealth after borrowing constraints are relaxed, causing more of them to have binding constraints over time, which in turn causes the average MPC to rise gradually to a new steady state value that is slightly lower than the original value. This dynamic pattern of the MPC suggests that a greater ability to borrow with credit cards could explain the lower effectiveness of the 2001 tax rebate. In addition, the model predicts that consumers choose to hold lower amounts of liquid assets for precautionary reasons when they have a greater ability to borrow unsecured debt.

Purpose - I analyzes risk-to-performance evaluated in the market using data from sale and lease back. Specifically, I analyze from the perspective of financial institutions that purchase sale and lease back based on the cases of investment by ship investment companies and acquisition of ships. Design/methodology/approach - I use 49 sale and lease back data from 2017 to 2019 for empirical analysis. Findings - The main results of this paper are as follows. First, after sale and lease back of domestic ships, the average amount of sales by the leased shipping company is 25.1 billion won, the average amount of investment by the purchased financial institution is 14.6 billion won (60%) and the average length of the ship is nine years. In ship finance, sale and lease back is deemed to be appropriately used as a means of restructuring for a large amount of money. Second, the main risk factor for sale and lease back of domestic ships is credit risk and can be measured in VaR in practice. As a result of the empirical analysis, the average credit risk burden ratio is 9%. As a major risk factor, low creditworthiness of restructuring companies is the key. Third, as a result of measuring the profitability of financial institutions that purchase sale and lease back of domestic ships at a net current price, it has an average value of 300 million won, but the deviation by case is very large. Fourth, the risk adjusted performance of sale and lease back of domestic ships is 0.54 on average compared to the total risk capital, and 0.52 compared to the stock-risk capital, and as with profitability earlier, the deviation of each case is very large and misaligned. In order to boost the sale and lease back market for large and long-term assets, in order to overcome low profitability as a prerequisite for future participation of commercial purchased financial institutions, it is expected that purchase decisions based on expectations versus risk will be necessary. Research implications or Originality - The results of this paper are expected to broaden the understanding of sale and lease back and foster the ability to assess long-term risk and performance. Based on this, it is believed that rapid restructuring of companies through sale and lease back of large amounts of long-term assets will greatly increase the utility of the domestic financial market.

In this study, a study was carried out to see what influence low-cost carrier's e-service quality has on low-cost carrier customers' perceived value and customer satisfaction and what impact the results have on customer loyalty based on the results of previous studies related to e-SERVQUAL, an e-SERVQUAL measurement model for general e-commerce. In addition, a survey of consumers who have experienced using low-cost carrier experience through web sites was conducted. For the analysis of the data collected, SPSS 18.0 was used to conduct frequency analysis, factor analysis, reliability analysis, correlation analysis, and regression analysis and thus to test a hypothesis. Research findings showed that perceived value and customer satisfaction are closely related to customer loyalty, and it was also observed that the reliability factor on the service provided on the web site acts as an important influencing factor for customer loyalty in the perceived value and security factors such as payment by credit cards and protection of personal information serve as important one in terms of customer satisfaction. This study has its limitation in that samples of users who have experienced low-cost carrier are concentrated on specific ages and professions. In the future, it is required to conduct further studies on whether difference is made on the importance of measurement factors related to e-service quality by gender, age group, occupation, and e-service quality.

With the revision of the Credit Information Use and Protection Act in August 2020, the MyData service based on open banking policy will take effect in January 2022. Nonetheless, the previous studies focused on the legal system or security-related issues of such service. Therefore, this paper conducted an empirical study on financial consumers aged 20 or older nationwide to analyze the factors which influence the intention to use MyData services based on open banking. Five characteristics representing open banking-based MyData service were derived through prior research, and a research model that combined value-based adoption model and privacy calculus theory was presented. The proposed research model and the relationship of its variables was analyzed using a sample of 400 users that is randomly selected. The results of empirical analysis showed that personalization had the greatest influence on benefits and reliability on sacrifice among service characteristics. They also suggested that MyData operators should devote themselves to providing customized services optimized for customers and establishing trust relationships. It was confirmed that both usefulness and enjoyment had a great influence on perceived value, and in terms of sacrifice, the burden of financial costs had a greater influence than privacy concerns. This study is meaningful in that it explored the psychological propensity of financial consumers to identify service utilization factors and presented a new approach that can contribute to the successful settlement of the domestic MyData industry.
