    Advances in partial disassembly line balancing: A state-of-the-art review
    Güler, E; Kalayci, CB; Ilgin, MA; Özceylan, E; Güngör, A
    As sustainable manufacturing practices increasingly prioritize the efficient and environmentally conscious disassembly of products, understanding the nuances of partial disassembly line balancing (PDLB) becomes essential. In our study, we conducted an in-depth analysis of 53 PDLB studies, published from 2008 to 2024, to understand the current trends and gaps in this domain. Our research methodology involved a systematic collection of material, descriptive analysis, careful category selection, and rigorous material evaluation. This approach enabled us to construct a comprehensive taxonomy tailored to PDLB, distinguishing it from classical disassembly line balancing (DLB) literature. Our findings reveal a noticeable surge in PDLB research in the last three years, reflecting its growing relevance in sustainable manufacturing. The study highlights that deterministic disassembly conditions, economic performance indicators, and iterative heuristic approaches are the focal points in recent PDLB research. This insight is critical for guiding future investigations in the field. Our taxonomy not only categorizes existing research in PDLB but also sheds light on under-explored areas, offering a clear direction for upcoming studies. This paper contributes to the literature by providing a detailed review of PDLBspecific elements such as problem characteristics, disassembly levels, objectives, constraints, and solution methods, thus paving the way for further advancements in sustainable manufacturing practices.

    Objective: The aim of this study was to evaluate the effectiveness of cryotherapy on the prevention of oral mucositis (OM) and on the oral pH value in patients with multiple myeloma undergoing autologous stem cell transplantation. Data Sources: This nonrandomized controlled clinical trial was carried out in Bone Marrow Transplant Centers of three hospitals with total 32 patients. In addition to standard oral care, a total of 80 minutes of cryotherapy was applied to the experimental group. OM was assessed according to the World Health Organization's Oral Toxicity Scale before chemotherapy and for 21 days after chemotherapy (every day in the first 14 days, then every other day until the 21st day [if not discharged]). Conclusion: According to the findings, cryotherapy did not change the incidence of oral OM, and neither affected the severity of nor decreased the duration of it. Oral pH value was found to be significantly different between the patient groups only before and 1 day after chemotherapy. Implications for Nursing Practice: Cryotherapy is an inexpensive, easy-to-use method with no side effects; it would be beneficial to continue cryotherapy to prevent the development of OM in patients with cancer receiving drugs with a short half-life such as melphalan. It is also recommended to conduct further studies with different chemotherapy drugs with short half-lives to determine its effect on the prevention of OM development. (c) 2021 Elsevier Inc.
