In recent decades, financial crises in various countries have often been preceded by the rise in non-performing loans (NPLs) in the banks' asset portfolios. The increase in NPLs is proven to have adverse impact on the banking sector so that understanding the determinant of NPLs is immensely crucial to ensure the efficiency and soundness of the overall economy. This study aims to shed light on bank-specific factors that affect loan default problems in developing countries whose banking sectors play a major role in the overall economy. This study analyzes panel data sets of 36 commercial banks listed in the Indonesian Stock Exchange during the period 2008-2015. Applying fixed-effects panel regression model reveals that Indonesian banks' profitability and credit growth negatively influence the number of NPLs. Moreover, banks with higher profitability are proven to have lower NPLs because they can afford adequate credit management practices. Likewise, banks with higher credit growth evidently have lower NPLs in the sense that they demonstrate more specialized lending activity and thus have better credit management systems. These findings imply that, in order to lower loan defaults that can deteriorate banks' asset quality, banks should maintain their level of profitability and increase, rather than decrease, their credit supply to debtors.

The introduction of radio frequency identification (RFID) technology into cold chain system will be essentials for the better quality preservation of chilled products in the near future. The object of this study is to analyze the trends of international standardization activity for cold chain system and RFID packaging. The standardization of RFID technology is related to SC31 of ISO/IEC JTC1. The established standard from EPCglobal includes the air interface of UHF substitute actors, the control of EPC tag data and the event collected from RFID readers, the directory services and information storage of ONS and EPCIS, and securities. Also, EPC standards include the sensor functions of the cold chain. In Korea, the RFID packaging related techniques and their engineering standard are less studied as compared with Europe or North America. For effective application of RFID in the cold chain and packaging, scientific and systematic researches on RFID, including technical standards for domestic RFID frequency, will be key elements for preoccupation of these application techniques.

This research aims to evaluate the current state of technology of enterprises in Vietnam in comparison with several countries in the AEC economic community, thereby to propose several recommendations to Vietnamese enterprises in order able to promote technology innovation activities, create competitiveness with enterprises in the region. Qualitative research methods are used through statistics and comparative descriptions from data collected from various sources: WEF, World Bank, CIEM, General Statistic Office. The study results show that Vietnamese enterprises still have many limitations in technology, originated from their small business scale (capital and labor), the current research capacity is still low, the funding for this activity is not high and the accessibility of the capital is still difficult. According to the Global Competitiveness Index, Vietnam's science and technology indexes are low compared to other AEC-developed countries including the availability of the latest technology; the acquisition of technology at the enterprise level; the capacity of improvement; quality of scientific research organizations..., which shall be a major barrier for Vietnamese enterprises to have to overcome to be able to create the competitiveness when entering the global market. From then on, the authors proposed solutions for two subjects, enterprises and government, to help Vietnamese enterprises to overcome this barrier.

Purpose: This study aimed to develop a scale measuring the Patient-Centered Nursing Culture (PCNC) and provide a basic tool to improve PCNC in Korea. Methods: A conceptual framework and construct factors were extracted through extensive literature review and in-depth interviews with nursing professionals. In total, 59 items were derived based on the pilot survey. Data were collected from 357 nurses working at general hospitals and analyzed for verifying the reliability and validity of the scale. Results: Nine factors containing 54 items were extracted from the exploratory factor analysis to verify the construct validity. The nine factors were top management leadership, policy and procedure, education and training, middle management leadership, supportive teamwork, nursing workplace environment, professional competence, patient-centered nursing activity, and nurses' values. These items were verified by convergent, discriminant, and concurrent validity testing. The internal consistency reliability was acceptable (Cronbach's ${\alpha}=.96$). Conclusion: The developed PCNC scale is expected to be used as the tool for the development of theory and improvement of PCNC, the empirical testing for cause and effect of PCNC, the development of interventions, education and training programs for improving PCNC, and indicators for evaluation or accreditation of hospital service quality.

This paper conducted a feasibility study by applying an Internet of Things and Artificial intelligence-based management system for the elderly living alone in an aging society. The number of single-person families over the age of 50 is expected to increase, and problems such as health, safety, and loneliness may occur due to aging. Therefore, by establishing an IoT-based care system for the elderly living alone, a stable service was developed through securing a rapid response system for the elderly living alone and automatically reporting 119. The participants of the demonstration test were subjects under the jurisdiction of the "Seongnam Senior Complex," and the data collection rate between the IoT sensor and the emergency safety gateway was high. During the demonstration period, as a result of evaluating the satisfaction of the IoT-based care system for the elderly living alone, 90 points were achieved. We are currently in the COVID-19 situation. Therefore, the number of elderly living alone is continuously increasing, and the number of people who cannot benefit from care services will continue to occur. Also, even if the COVID-19 situation is over, the epidemic will happen again. So the care system is essential. The elderly care system developed in this way will provide safety management services based on artificial intelligence-based activity pattern analysis, improving the quality of in-house safety services.

Purposes: This study aimed to identify the relationships among personal and organizational communication skills, occupational stress, and patient safety activity levels of two nursing workforce groups (nurses and nursing assistants) who provide integrated nursing care services. Methodology: The study design is a cross-sectional study. Seventy-one nurses and forty-three nursing assistants working in the integrated nursing care service wards participated in this study. The data were collected using a self-reported questionnaire from June to July 2021. The relationships among the variables were analyzed using the Pearson correlation coefficient. Findings: Nurses' personal communication skills (r=.294, p=.013), organizational communication skills (r=.408, p<.001), and occupational stress (r=.243, p=.041) were associated with their patient safety activities. However, nursing assistants' personal communication skills, organizational communication, and occupational stress were not correlated with their patient safety activities. Practical Implication: Patient safety activities of nurses were related to their communication skills and occupational stress, but nurse assistants were not. Therefore, nurses should encourage nursing assistants to responsibly engage in patient safety activities and supervise their works appropriately to achieve high-quality care.

We had passed through a serious water pollution with a rapid urbanization and industrialization in the 1960's. Seoul Chunggyechun Sewage Disposal System set uP in 1966 and finished in 1976, as the first sewage disposal system in Korea, had covered only 4 percentage of the sewage disposal system per capita for 10 years. Through holding the Asian Games in 1986 and the Olympic Games in 1988, we expanded the sewage disposal system so that it became increased 18 percentage of the population in 1986. Finally, we have installed about 60 sewage disposal system by 1994 for a large environmental investment which was critically caused by "Phenol Accident in Nakdong River" . Now, the sewage disposal system per capita covers 42 percentage and the activity for water quality improvement is going on rapidly. The method of sewage disposal is mainly "activated sludge process" . However, the technical ability for the sewage disposal has largely developed since 1991 so the "extended aeration process" is used in Po$\v{u}$n, Tangyang, Mun$\v{u}$i, "rotating biological contact process" in Onch$\v{u}$ng, Pukok, and "oxidation ditch process" in K$\v{o}$ch'ana.
