Total debt in the People's Republic of China surged to nearly 290% as a ratio to GDP by the second quarter of 2016, mostly on account of non-financial corporate debt. The outpouring of credit to stem the impact of the global financial crisis accentuated industrial overcapacity in traditional sectors, such as steel, cement, and energy, while feeding asset bubbles in the property, equity and bond markets. At the Chinese corporate level, this has translated into weakened fundamentals and a fall in industrial profits, particularly of SOEs. As debtors struggle to service interest payments, non-performing loans (NPLs) have been on the rise. This paper assesses the financial fragility of the Chinese economy by looking at risk factors in the non-financial sector. We apply quantile regressions to a dataset containing all Chinese listed companies in Standard & Poor's IQ Capital database. We find higher sensitivity over time of corporate leverage to some of its key determinants, particularly for firms at the upper margin of the distribution. In particular, profitability increasingly acts as a curb on corporate leverage. At a time of falling profitability across the Chinese non-financial corporate sector, this eases the brake on leverage and may contribute to its continuing increase.

Purpose: In the past, the South Korean government made various efforts to attract Chinese tourists, resulting in gradually more inbound tourists. In 2016, the number of Chinese tourists to South Korea peaked at 8.06 million and became the top source market. Nevertheless, increasing numbers of consumers choose to adopt the mobile payment tool instead of cash and credit cards in modern times with developed IT services. Research design, data, and methodology: IBM SPSS AMOS 23.0 and IBM Statistics 23.0 were used to analyze the data, which was collected from hotel employees in China from March 25 to May 10. Results: First, Interactivity, security, convenience, local information supply and user interface had positive effects on satisfaction and reliability. Second, it was believed that the convenience of Alipay played a positive role in increasing reliability and satisfaction through verification. Third, the role of use rate was found to be important in the development of Alipay functions. Conclusions: Based on the result, an analysis on the development of the Alipay market and the use of Alipay in South Korea is warranted. Furthermore, this paper will serve as a basis for flexible strategic plans for the development of Alipay and SMEs in South Korea.

신용평가 연구에서 부도와 정상차주에 대한 판별력을 평가하는 방법으로 Receiver Operating Characteristic(ROC)와 Cumulative Accuracy Profile(CAP) 곡선을 사용한다. ROC 곡선에서 최적의 분류정확도를 갖는 분류점과 CAP 곡선에서 최대의 이익을 나타내는 분류점은 일반적인 정확도의 개념으로 정의된 동일한 성과를 가진 접선을 사용하여 구한다. 본 연구에서는 정확도의 대안적인 측도로 진실율을 제안하고, 이 진실율을 이용하여 ROC와 CAP 곡선에서 대안적인 최적의 분류점을 구한다. 대부분 실제 차주의 모집단에서 부도차주는 정상차주보다 훨씬 수가 적다. 이러한 경우에 진실율은 정확도보다 비용함수의 측면에서 더욱 효율적일 수 있다. 진실율을 이용하여 최적의 분류정확도를 나타내는 분류점과 최대의 이익을 의미하는 분류점에 대응하는 스코어는 동일하다는 것을 보였으며, 이 스코어는 부도와 정상 차주의 분포함수의 동일성을 검정하는 Kolmogorov-Smirnov 통계량에 대응하는 스코어와도 일치하는 것을 발견하였다.

Purpose: The purpose of this study is to investigate how much continuous investment in human capital contributes to increasing labor productivity at not only individual companies but also at the national level, and causes fundamental as well as increases for labor-management conflicts. The current research aimed to empirically demonstrate the importance of human capital investment and furthermore, based on the effect of human resource investment on labor productivity, also re-examine the role of the Labor Commission as well. Research design, data, and methodology: This study was conducted by the Korea Information Service-Financial Accounting System (KIS-FAS) using representative panel data operated by countries to measure whether long-term investment in corporate human resources affects labor productivity. Results: Two distinctive summarized results of the analysis in the Korea Credit Ratings data showed that there was a high positive correlation between corporate human resource investment and economic performance for a ten-year period from 2009 to 2018. Conclusions: The present study concluded that the role of the labor committee should be effectively formed by the labor as a mediation agency and that the role of the mediation committee members should focus more on how to strengthen the human resources management of the union.

의학통계와 신용평가 분야에서 혼합분포함수를 판별하는 최적분류점 추정하기 위하여 판별력을 측정하는 다양한 정확도 측도들이 존재한다. 최근에 혼동행렬 빈도수로 표현되는 Matthews의 상관계수와 정밀도와 재현율의 조화평균인 F1 통계량의 정확도 측도들이 최적분류점을 추정하는데 연구되었다. 본 연구에서는 이런 정확도 측도들 중에서 표본크기에 의존하는 정확도 측도들은 두 표본크기 차이가 많은 경우에 최적분류점을 설정하는데 적절하지 않음을 발견한다. 그리고 대안적인 정확도 측도로 혼동행렬의 비율들의 함수인 상관계수를 정의하고, 이를 최대화하는 분류점을 최적분류점으로 추정하는 방법을 제안하고 이 방법의 유용성과 활용성에 대하여 토론한다.

실내 위치 측위 관련 IPS(Indoor Positioning System)의 기술이 계속적인 연구 및 개발이 진행되고 있으며, 이에 따른 핑거프린팅 및 삼변 측량 기술이 지속적으로 연구되어 왔다. 하지만 이와 같은 기술은 AP(Access Point)를 이용하여 측위하기 때문에 광범위 측위에 있어 불안전한 RSSI 값의 측정으로 인한 측위 정밀도가 신용적이지 않다. 본 논문에서는 이와 같은 광범위 내 정밀 측위 문제점을 개선하고자 기존의 핑거프린팅 기법의 Cell 구성이 아닌 Sector 개념을 도입하였다. 각 Sector는 서로 간에 관여를 하지 않고 해당 Sector 내에서만 핑거프린팅 기법을 수행하여 효울 및 정밀성을 고려한 시스템을 제안하며, 기존의 핑거프린팅과 비교하여 효율성을 수학적 기법으로 입증하였다.

Although the microfinance sector in Bangladesh is mainly driven by Non-Governmental-Organizations (NGOs), there are other types of Microfinance Institutions (MFIs) that also provide financial services to the poor. Despite the criticism of microfinance programs, the current poverty situation in Bangladesh still requires such programs for consistently battling poverty. Hence, the aim of this paper is to profile the microfinance sector based on their legal status and investigate any possible differences (if any) between them in various aspects. After a thorough investigation of the sector, it was found that around 33 million of the clients are being served by the mainstream MFIs (NGO and Grameen Bank) while another 10-15 million clients are served by other types of MFIs (financial cooperatives, credit unions, various ministries etc.), accounting for the one-third of the total population in Bangladesh. While the mainstream MFIs basically works with poor, other categories of MFIs are concerned with relatively wealthy clients. Looking into the financial performance and social intermediation of the MFIs, the NGO-MFIs performed better than other types of MFIs in the sector.

Biomass is one of the most competitive renewable energy resource and can be used for heating for rural applications. A economic assessment was made of biomass heating, using the tool BIOH2000 from $RETScreen^{\circledR}$ International Clean Energy Decision Support Centre. For a 260kW heating system for 50 farm houses, the assessment showed a very promising results. Internal rate of return was $19.7\%$ and year-to-positive cash flow was 5.1 years. Relative price of biomass over fossil fuel significantly affected the economic feasibility of the project. Heating demand was directly related to annual demand of biomass and economic feasibility. Relative cost of distribution pipe over the total initial costs also affected the economic feasibility of the project. The economic feasibility was expected to be improved by the probable greenhouse emission reduction credit and reduction of initial costs through utilizing existing heating system for peak or back up heating system.

This study empirically examines the proposition that the domestic fundamentals of a nation can emerge as absorptive capacity factors to reap the benefits of inward FDI. The study is contextualized in Asia, set from1982 to 2017, and data is grouped into low-income and lower-middle-income economies, in comparison to high-income and upper-middle-income economies, catering to different geographical regions within Asia. The investigation is based on a series of absorptive capacity factors such as infrastructure, human capital, domestic credit, and health indicator. The methodological analysis is premised on dynamic panel structure and employs the Generalized Method of Moments (GMM) estimation technique. The empirical findings suggest that that the infrastructure variable appears to be the major absorptive capacity factor for both groups of countries. The health indicator, on the other hand, can help reap the benefits of inward FDI, but only if the threshold level is met. The selected economies must achieve this threshold level to reap the benefits of FDI. To absorb the benefits of inward FDI, countries must be proactive in providing sound infrastructure and implementing proper healthcare measures.

Risk financing is defined as the methods applied to fund risk treatment and the financial consequences of risk. It is a major component of the transfer of risk and the retention of risk which are, in turn, parts of the risk treatment process. This study applied the general guidelines on risk financing to product liability risk. Product liability risk occurs when potential defects in the process of design, production, and distribution lead to accidents resulting in fatal, financial, and environmental loss. Risk on product liability may be financed in many different ways, each of which may be used singularly or in combination. The most popular and recommendable way suggested in the guidelines is the retention or use of reserves, transfer, credit or insurance.
