Inflammatory bowel disease (IBD) is a global disease that is in increasing incidence. The gut, which contains the largest amount of lymphoid tissue in the human body, as well as a wide range of nervous system components, is integral in ensuring intestinal homeostasis and function. By interacting with gut microbiota, immune cells, and the enteric nervous system, the intestinal barrier, which is a solid barrier, protects the intestinal tract from the external environment, thereby maintaining homeostasis throughout the body. Destruction of the intestinal barrier is referred to as developing a "leaky gut," which causes a series of changes relating to the occurrence of IBD. Changes in the interactions between the intestinal barrier and gut microbiota are particularly crucial in the development of IBD. Exploring the leaky gut and its interaction with the gut microbiota, immune cells, and the neuroimmune system may help further explain the pathogenesis of IBD and provide potential therapeutic methods for future use.

Purposes: The purpose of this study is to analyze nurses' perception on the clinical career ladder system which was introduced to enhance the nursing capabilities in general hospital. Methods: Research data has been collected for approximately 30 days since March 28, 2017 from 171 nurses who had been involved in the clinical career ladder system, 177 nurses who had not participated, and a total of 348. Finding: The study results showed that nurses' perception on the cost effectiveness of clinical career ladder system is significantly different depending on the sex, age, program experience, personal stage in the clinical career ladder system and the individual's health condition. In addition, the nurses' willingness to pay for the clinical career ladder system was significantly associated with their department and the needs for the system. With adjusted age, gender, position, education and marital status, nursing competency was 8.71(95% Confidence Interval; 4.79 to 12.63) in the presence of system experience, but the perception on clinical career ladder system was 4.34(95% Confidence Interval; -6.84 to -1.84). Practical Implications: Based on the study results, we expect that more hospitals introduce the clinical career ladder system and also use these study results as basic data for securing excellent nurses.

The Long-Term Care Hospital (LTCH) accreditation system was initiated in 2013 in the form of mandatory accreditation system in order to improve patient safety and the quality of medical service at LTCHs. By June 2016, the accredited LTCHs were 76.2%. This research was conducted to review the implementation process in the first cycle and to promote development of the second cycle of LTCH accreditation system. There are some changes which reinforced the accreditation standards, accreditation survey, and public access to accreditation results in order to strengthen patient safety in the first cycle LTCH accreditation system. LTCHs which participated in the accreditation system achieved certain outcomes in respect to patient safety and employee satisfaction. However, there are several urgent problems in placement criteria of night duty health care providers, reinforcement plans in the accreditation system, and incentives for accredited hospitals. In order to solve these problems, the most important thing is to clearly recognize the fact that the healthcare accreditation system is not the means for control and regulate hospitals but a system to induce hospitals to continue to strive for improvements in patient safety and medical service quality. In addition, it is required that LTCHs, accrediting agency and the Ministry of Health and Welfare compromise and cooperate to seek solutions every time issues related to the accreditation system arise.
