Radiographic osteolysis after total shoulder arthroplasty (TSA) remains a challenging clinical entity, as it may not initially manifest clinically apparent symptoms but can lead to clinically important complications, such as aseptic loosening. A thorough consideration of medical history and physical examination is essential to rule out other causes of symptomatic TSA-namely, periprosthetic joint infection-as symptoms often progress to vague pain or discomfort due to subtle component loosening. Once confirmed, nonoperative treatment of osteolysis should first be pursued given the potential to avoid surgery-associated risks. If needed, the current surgical options include glenoid polyethylene revision and conversion to reverse shoulder arthroplasty. The current article provides a comprehensive review of the evaluation and management of osteolysis after TSA through an evidence-based discussion of current concepts.

In The White Card (2019), Claudia Rankine dramatically interrogates whiteness's persistent, reflexive habit of trying to preserve a state of innocence, expressing her vision of how this tendency blinds white liberal subjectivity to the structural reality of institutionalized racism in America. Rankine's exposure of the invisibility to which people of color are usually consigned by American whiteness is inseparable from her critical interrogation of how the hypervisibility of victims of racial violence provides white liberal subjectivity opportunities to intervene and feel good about itself. What Rankine enacts in the play is a process of repetition and revision, signifyin(g) on racial violence and its history; acts of racial violence continue to accrete, and her act of signifyin(g) on the countless acts of racial violence in America conveys the understanding that this text cannot be rewritten if white America continues to attend solely to individual, ostensibly isolated, acts of racial injustice.

Software visualization can assist developers to understand a software system and change its code. The recent development of bottom-up visualization tools demonstrates the advantages by revealing the code that is directly related to a software evolution task. However, the information provided by these tools is limited to the code already investigated by the developers in that task session. To broaden the scope and provide the code information that developers should explore, we propose to present the latest revision of a software system via a class diagram. When a developer clicks on a button, the proposed tool reveals the code changes committed to a configuration management system, and facilitates the understanding of code changes. We also conduct case studies illustrating the advantages of the proposed tool.

IMO(International Maritime Organization) is existed the movement for revising ISM Code so that the maintenance history and the trouble information given trading in a ship can be transferred. An empirical analysis was made on the influence that will have upon shipping industry through surveying on the recognition on ISM Code revision in employees of the relevant field and on the expected problems given being amended ISM Code as the above. In conclusion, the positive effect is judged to be more in the aspect of ship safety, which is the aim of ISM Code, rather than the negative effect, which may take place given being revised ISM Code. In other words, the clean market can be formed through this because fairness is maintained on both sides given trading in a ship by which opening the maintenance record and the trouble history is applied equally to a buyer and a seller. Ships can be reduced a loss of time and cost in preventing similar problems and seeking solution that may appear in important equipments, through this maintenance record. Also, based on these materials, it comes to be available for analyzing a risk of ship and preventing and managing a risk, thereby being increased ability of maintenance and repair in a ship, resulting in being judged to likely contributing to ship safety and environmental-pollution prevention.

Since the establishment of the Korean Society of Plant Taxonomists (KSPT) on Dec. 13, 1968, the professional manpower training and research activities have been analyzed. The survey method was based on the homepage of the KSPT and the Korean J. Pl. Taxon, and on data provided by each university about professional manpower. Over the past 50 years, a total of 680 specialists in plant taxonomy have been trained, consisting of 537 master's degree holders (274 males, 263 females) from 30 universities and 143 PhDs (97 males, 46 females) from 26 universities, and the number has increased significantly since 1998. With regard to changes in the field of research over the last ten years, revision papers were the most common in the period of 1988-1997 (72%), but this rate has decreased to 51% over the last ten years, while the number of unrecorded papers has increased to 28%. In the 629 revision papers on taxa, 49% of the taxa belong to Asteraceae, Ranunculaceae, Cyperaceae, Liliaceae, Rosaceae, Fabaceae, Apiaceae, Lamiaceae, Orchidaceae, Oleaceae, Euphorbiaceae, Polygonaceae, and Amaryllidaceae. With regard to changes in research methods, the number of morphological papers increased from 6% to 51%, while pollen papers have decreased from a rate of 20% to only 2%. Chromosome studies account for 3-4%, chemotaxonomic studies 2%, and DNA studies remain low at 3-16%. The percentage of papers in English now stands at 43%, mainly due to the increased number of papers on unrecorded species.
