Mathematical representation is an idea interpretation form of solving mathematical problems. The process of mathematical representation is essential to pay attention to, especially in carrying out transformations between forms of representation, because it impacts the final solution obtained. This study describes the flow of students' thinking in carrying out the transformation process from visual to symbolic representation. This descriptive research was carried out with a qualitative approach. This research phase includes preparing representation tests and interview guidelines, giving tests to 48 students, conducting interviews with selected students based on the accuracy of the mathematical representations produced, and evaluation. The evaluation is carried out by reducing the results of the incorrect representation test, presenting visual and symbolic representation data and the transformation process, and concluding the transformation process. The result of the transformation process from visual to symbolic representation in solving the problem of the area under the curve is carried out with a flow of thought, namely translating the shape of the polygon area into a collection of rectangles, determining the width and length of the partition of the polygon area, and determining the area of the polygon area as a collection of rectangles. In determining the area as a collection of rectangles, there are two different processes, making a mathematical model in the form of sigma notation and addition. This study provides insight into the flow of thinking in changing between forms of mathematical representation in the hope that it can anticipate errors in solving the broad problem under the curve.

ObjectivesTo gain insight into current methods and practices for the assessment of competences during rheumatology training, and to explore the underlying priorities and rationales for competence assessment.MethodsWe used a qualitative approach through online focus groups (FGs) of rheumatology trainers and trainees, separately. The study included five countries—Denmark, the Netherlands, Slovenia, Spain and the United Kingdom. A summary of current practices of assessment of competences was developed, modified and validated by the FGs based on an independent response to a questionnaire. A prioritising method (9 Diamond technique) was then used to identify and justify key assessment priorities.ResultsOverall, 26 participants (12 trainers, 14 trainees) participated in nine online FGs (2 per country, Slovenia 1 joint), totalling 12 hours of online discussion. Strong nationally (the Netherlands, UK) or institutionally (Spain, Slovenia, Denmark) standardised approaches were described. Most groups identified providing frequent formative feedback to trainees for developmental purposes as the highest priority. Most discussions identified a need for improvement, particularly in developing streamlined approaches to portfolios that remain close to clinical practice, protecting time for quality observation and feedback, and adopting systematic approaches to incorporating teamwork and professionalism into assessment systems.ConclusionThis paper presents a clearer picture of the current practice on the assessment of competences in rheumatology in five European countries and the underlying rationale of trainers’ and trainees’ priorities. This work will inform EULAR Points-to-Consider for the assessment of competences in rheumatology training across Europe.

Preservation of library materials or library collections is an effort made so that library materials can be used by future generations. This paper describes the "Malaysian" binding method used by the Sub Division of Technical Binding Materials of the National Library of Indonesia in preserving the collection of periodicals such as tabloids and newspapers. Apart from that, this paper also describes some of the advantages and disadvantages seen in the use of the "Malaysian" method as well as the early history of using this method in preserving the collection of periodicals in the National Library of Indonesia. This writing aims to make readers, especially library managers, know and gain insight into the "Malaysian" binding method. This writing method is through descriptive research with a qualitative approach. Methods of data collection are carried out through the field research, interviews, and literature study. The results show that the National Library of Indonesia uses this method after studying it from Malaysia in May 1990. From observations it is also known that this method has several advantages, namely the binding result is stronger, the collection is more preserved, the binding can be assembled and has an aesthetic side. Meanwhile, the disadvantages of this binding method are that the process tends to be longer, more expensive, cannot be put on too many shelves because the collection will shift backwards, the pages tend to come off easily if the stitches are not strong enough, and can only be used in binding periodical collections.
