Purpose: This study was conducted to identify changes in limb circumferences among patients admitted to the intensive care unit (ICU) and related factors. Methods: We conducted a prospective observational study with 27 patients from 3 ICUs at a university hospital located in B city of Korea, from September 1 to October 30, 2015. The circumferences of the left and right upper arms, thighs, and lower legs were measured on the first, third, fifth, and seventh days of ICU admission. Information on the related factors was collected from the medical records. The data were analyzed using a linear mixed model method. Results: The limbs circumferences significantly reduced from day 3, and the changes continued till day 7. These changes were related to the gender of the subjects, restraints application, use of steroids, and continuous renal replacement therapy. Conclusions: Based on the above results, it can be concluded that ICU-acquired weakness begins before the third day of admission. Thus, early mobilization protocols for ICU patients need to be developed and implemented in order to improve long-term outcomes. [ABSTRACT FROM AUTHOR]

Objective: This study examined the code of ethics, which offers guidelines for early childhood teachers’ ethical decisions and practices. Results and Conclusion: In the second section of this paper, the meaning of the code of ethics is reviewed. The issues of the code of ethics are also investigated to resolve moral and ethical dilemmas and to maintain high standards of professional conduct in early childhood care and education. In the third section of this paper, a comparison of the ethical codes in South Korea, Japan, the United Kingdom, and the United States is conducted. Based on the results raised in relation to the code of ethics principles and the results of comparing domestic and international ethics codes, the fourth section of this paper focuses on three topics in the current and future direction of the Korean code of ethics: (a) concreteness and clarity, (b) switching from the viewpoint of least harm to the viewpoint of maximum benefit, and (c) the range of benefits of the code of ethics. Then, including the existence of the last two codes of ethics, we discuss the direction of future difficulties currently associated with the situation in Korea. [ABSTRACT FROM AUTHOR]
