Purpose: This study was to classify elderly in long-term care hospitals for using Resource Utilization Group(RUG-III) and to consider feasibility of payment method based on RUG-III classification system in Korea. Method: This study designed by measuring resident characteristics using the Resident Assessment Instrument-Minimum Data Set(RAI-MDS) and staff time. The data were collected from 382 elderly over sixty-year old, inpatient in the five long-term care hospitals. Staff time was converted into standard time based on the average wage of nurse and aids. Result: The subjects were classified into 4 groups. The group of Clinically Complex was the largest(46.3%), Reduced Physical Function(27.2%), Behavior Problem(17.0%), and Impaired Cognition(9.4%). The average resource use for one resident in terms of care time(nurses, aids) was 183.7 minutes a day. Relative resource use was expressed as a case mix index(CMI) calculated as a proportion of mean resource use. The CMI of Clinically Complex group was the largest(1.10), and then Reduced Physical Function(0.93), Behavior Problem(0.93), and Impaired Cognition(0.83) followed. The difference of the resource use showed statistical significance between major groups(p<0.0001). Conclusion: The results of this study showed that the RUG-III classification system differentiates resources provided to elderly in long-term care hospitals in Korea.

Purpose: This study aimed to investigate possible ways to expand the services of home-visit nursing through a review of the progress, achievements, and obstacles of home-visit nursing; a pilot project of an integrated home-service; the application of the Omaha System; as well as a case analysis of providing home-visit nursing services. Method: An integrated review was conducted using various source materials, including laws, previous studies, and a case analysis. Results: In case analysis of providing visiting nursing service, rehabilitation nursing, end-of-life nursing, and dementia care showed high nursing needs. It was necessary that the various home visit nursing services in the intervention area of the Omaha System, administrative services, case management, and center operation activities were all included in the payment systems of long-term care insurance. Conclusion: In the future, home visit nursing services of long-term care insurance should be reborn in the form of a center for integrated case management in the community, which would set long-term goals until the time of a client's death and encompass the realm of human rights for health, quality of daily life, and a dignity of life.

The rapidly aging trend of Korea is a major factor that threatens the sustainability of the long-term care insurance system. Therefore, looking at how Japan and Germany mitigated the financial burden when they managed similar long-term care insurance systems will provide important implications for improving the Korean system in the future. The study was conducted using the literature review method, and the "country" was set as a unit for the case analysis. The three countries selected are Korea, Japan, and Germany. Recently in Korea, the insurance premium rates of all subjects have been rapidly rising, which can exacerbate the issue of intergenerational equity. On the other hand, Japan has responded to the aggravating finances for long-term care insurance due to aging by raising coinsurance for selected groups like the wealthy elderly. Germany is selectively raising the insurance premium rates by additionally increasing the premium rate for childless recipients. A more preventive and quality-oriented care service plan can be promoted by referring to the recent changes in Japan and Germany. In addition, a more effective and selective increase in payment burden in Japan and Germany could be considered in response to a recent equity issue in Korea.

The Korean Long-Term Care Insurance (K-LTCI) provides financial support for long-term care service to people who need various types of assistance with daily activities. As the number of elderly people in Korea is expected to increase in the future, the demand for long-term care insurance would also increase over time. Projection of future expenditure on K-LTCI depends on the number of beneficiaries within the grading system of K-LTCI based on the test scores of applicants. This study investigated the suitability of mixture distributions to the model K-LTCI score distribution using recent empirical data on K-LTCI, provided by the National Health Insurance Service (NHIS). Based on the developed mixture models, the number of beneficiaries in each grade and its variability under the current grading system were estimated by simulation. It was observed that a mixture model is suitable for K-LTCI score distribution and may prove useful in devising a funding plan for K-LTCI benefit payment and investigating the effects of any possible revision in the K-LTCI grading system.

The current standards and specifications for the road pavement construction have been developed based on materials and construction methods. The pavements constructed in accordance with those specifications do not guarantee high performance of pavements since they do not consider long-term performance of pavements. Therefore, as part of the study to develop performance-based construction standards for pavements, the payment adjustment methods based on the pavement performance are currently being developed. This paper presents preliminary studies performed to develop the payment adjustment methods when there is deficiency in the concrete slab thickness that is one oi the most important factors for the pavement design and construction. First, the payment adjustment methods in USA were investigated. Then, the AASHTO failure equation, the relationship between slab thickness and stress, and the relationship between stress level and pavement life were employed to propose the payment adjustment concepts based on the pavement performance for the deficient slab thickness. The variation in the slab thickness according to measurement locations was investigated by taking cores. In addition, the measurement methods of slab thickness and the variation of measured thicknesses depending on performers were analyzed, and finally the methodology to develop the thickness deficiency ranges for the use in the payment adjustment methods was proposed.

Background: This study aims to develop a "Predictive Model for the Possibility of Collection Delinquent Health Insurance Contributions" for the National Health Insurance Service to enhance administrative efficiency in protecting and collecting contributions from livelihood-type defaulters. Additionally, it aims to establish customized collection management strategies based on individuals' ability to pay health insurance contributions. Methods: Firstly, to develop the "Predictive Model for the Possibility of Collection Delinquent Health Insurance Contributions," a series of processes including (1) analysis of defaulter characteristics, (2) model estimation and performance evaluation, and (3) model derivation will be conducted. Secondly, using the predictions from the model, individuals will be categorized into four types based on their payment ability and livelihood status, and collection strategies will be provided for each type. Results: Firstly, the regression equation of the prediction model is as follows: phat = exp (0.4729 + 0.0392 × gender + 0.00894 × age + 0.000563 × total income - 0.2849 × low-income type enrollee - 0.2271 × delinquency frequency + 0.9714 × delinquency action + 0.0851 × reduction) / [1 + exp (0.4729 + 0.0392 × gender + 0.00894 × age + 0.000563 × total income - 0.2849 × low-income type enrollee - 0.2271 × delinquency frequency + 0.9714 × delinquency action + 0.0851 × reduction)]. The prediction performance is an accuracy of 86.0%, sensitivity of 87.0%, and specificity of 84.8%. Secondly, individuals were categorized into four types based on livelihood status and payment ability. Particularly, the "support needed group," which comprises those with low payment ability and low-income type enrollee, suggests enhancing contribution relief and support policies. On the other hand, the "high-risk group," which comprises those without livelihood type and low payment ability, suggests implementing stricter default handling to improve collection rates. Conclusion: Upon examining the regression equation of the prediction model, it is evident that individuals with lower income levels and a history of past defaults have a lower probability of payment. This implies that defaults occur among those without the ability to bear the burden of health insurance contributions, leading to long-term defaults. Social insurance operates on the principles of mandatory participation and burden based on the ability to pay. Therefore, it is necessary to develop policies that consider individuals' ability to pay, such as transitioning livelihood-type defaulters to medical assistance or reducing insurance contribution burdens.

The exemption clause of recurring shipments refers to the insurer's exemption in Short-term Export Credit Insurance for the additional shipment which was shipped on board while any foregoing shipment was unpaid beyond its due date over 30 days. The recurring shipments are constituted with two factors: the due date of the foregoing shipment and the shipment date of the additional export. The exemption clause of recurring shipments has been eased by extending the grace period for payment up to 60 days from 30 days for the transactions between exporters and importers having the history of payments which were made customarily in delay. This research argues that the current grace period is for the buyers who customarily delay their payments, and that the insurer introduce a grace period for shipment in favor of exporters for the additional shipment which was delayed in on-boarding due to reasons beyond the control of exporters. In consideration of the waiting time and the on-boarding time at ports for container freight, shipments are frequently delayed, which entails those shipments to be indemnified by the exemption clause of recurring shipments. Roll-overs and Blank Sailings also cause the container freight to be delayed in on-boarding. This research is expected to contribute to further development of Short-term Export Credit Insurance in K-SURE.

This study investigates firm-specific financial variables that determine investment or speculative grades from the viewpoint of firms, which are one of the major stakeholders related to the credit rating. We employ an ordered probit model for our analysis with the sample data from 1999 to 2015 for listed firms in the Korean stock markets. For investment grades, operating margin, sales, market-to-book, dividend payment, capital expenditure ratio, and tangible asset ratio have a significantly positive impact on credit ratings. In the subsample for speculative grades, the coefficients of the dividend payment, retained earnings ratio, and capital expenditure ratio are significantly positive while short-term debt ratio and R&D expenditures have a significantly negative impact on credit ratings. For the analysis before and after 2009, when the Credit Information Use and Protection Act was strengthened after the global financial crisis, the coefficients of the capital expenditure ratio, cash ratio, and tangible asset ratio are significantly positive in the subsample for investment grades before 2009, but not significant after 2010. The coefficient of the long-term debt ratio is more significantly negative than that of the short-term debt ratio before 2009, for speculative grades, but short-term debt ratio has a more negative effect on ratings than long-term debt ratio after 2010. Surprisingly, the coefficient of the R&D expenditures is significantly negative in both investment and speculative grades since 2010. Our findings are inconsistent with the conjecture that the increase in R&D expenditures enhances the possibility of creating cash-flow by raising the investment growth opportunity, and thus affects positively the credit rating.

Ulaanbaatar city, the capital of Mongolia and the center of Mongolian economy, increasingly needs to have a long-term urban planning and a system to impose a tax on land effectively as insufficient development of land and the moving of nomad into urban areas increases during its rapid growth. Therefore, Mongolian government has to prepare a land management system which provides the infrastructure to improve work efficiency and service quality by integrating digitalized data about land and main facilities and sharing data between related departments. This research analyzed the environment to operate the existing land management system and working environment and redesigned database. Furthermore, it integrated all the existing systems, configured service network, and made working environment for land registration, land permission, land payment management to be processed online. With this, it provides the foundation to improve quality of people's life through the preparation of long term urban planning, clean tax administration of real estate, and reconsideration of efficiency about urban infrastructure investment.

Purpose - The UCP is recognized as the governing law for L/C transactions, but it covers only the general details of the transaction and does not cover all complex practices. In view of this limitation, this paper examines a negotiation transaction which is most actively utilized in L/C transactions via a thorough review of the UCP provisions, analyzes the problems of the negotiation clause in the UCP, and suggests appropriate countermeasures to deal with unnecessary litigation costs. By doing so, the parties involved in the negotiation transaction would be able to avoid financial costs such as having to pay for lawsuits. Design/methodology - The present study first differentiates the general types of L/Cs (e.g., sight payment L/C, deferred payment L/C, acceptance L/C, and negotiation L/C), explains and the Article 2 and Article 12(b) of the UCP 600 where the term 'negotiation' is used, digs into the drawbacks of 'negotiation' occurring under the UCP 600, and discusses solutions to the problems found by analyzing the drawbacks descriptively. Findings - After a review of the UCP provisions on negotiation in detail, several possible problems which may occur in practice were discovered. First, as the UCP stipulates, the negotiating bank will want to delay payment to the maximum extent possible and make payment on the banking day on which the issuing bank reimburses the amount. This may lead the beneficiary towards bankruptcy or put it in financial crisis. Second, when a fraudulent transaction occurs, the negotiating bank can neither request the issuing bank to reimburse nor can it exercise its recourse right against the beneficiary because it has obtained all the rights of the beneficiary by purchasing the documents. Third, there is a practice in which the beneficiary sells the documents to its transaction bank which is not the nominated bank if the nominated bank specified in the credit is located in a third country or the exporter has no relationship with the nominated bank in the credit. In this case, whether to accept this and reimburse the non-nominated negotiating bank entirely depends on the issuing bank's decision even though such practice frequently occurs in Korea. Originality/value - There has been little research effort pertaining to negotiation transactions in detail even though negotiation L/C transactions account for around 70% in world trade notwithstanding deferred payment L/Cs and acceptance L/Cs that are also negotiated in practice. Thus, if the negotiations clause under the UCP 600 provisions were reviewed and the drawbacks of the negotiation transactions most actively used in L/C transactions were identified and examined, specific countermeasures could ultimately help smoothen the operation of L/C transactions and prevent financial losses.
