Clinical Application of Automated Breast Ultrasound

Automatic breast ultrasound (ABUS) has been developed to compensate for the shortcomings of hand-held ultrasound (HHUS) and is mainly used for breast cancer screening purposes in women with dense breasts. Since 2021, ABUS has been covered by the Korean National Health Insurance System. It is important to scan the entire breast on ABUS and to identify the poor-quality images requiring re-scanning. In addition, a general understanding of the unique ABUS display mode, distinguishing benign from malignant lesions, the diagnostic performance of breast cancer screening, and the application of computer-aided detection/diagnosis systems is necessary to use ABUS efficiently. This review explores the acquisition method, image quality, and image characteristics of ABUS to improve general understanding of this procedure and its advantages over HHUS, so that ABUS can be applied efficiently in clinical practice.

Staging the Past: The Period Room in New Zealand

<p>Before 1940, few of the nation’s museums actively collected or displayed artefacts associated with the history of European settlement in New Zealand. Over the following three decades, an interest in ‘colonial history’ blossomed and collections grew rapidly. Faced with the challenge of displaying material associated with the homes of early settlers, museums adopted the period room as a strategy of display. The period room subsequently remained popular with museum professionals until the 1980s, when the type of history that it had traditionally been used to represent was increasingly brought into question. Filling a gap in the literature that surrounds museums and their practices in New Zealand, this thesis attempts to chart the meteoric rise and fall of the period room in New Zealand. Taking the two period rooms that were created for the New Zealand Centennial Exhibition in 1939 as its starting point, the thesis begins by considering the role that the centennials, jubilees and other milestones celebrated around New Zealand in the 1940s and 1950s played in the development of period rooms in this country, unpacking the factors that fuelled the popularity of this display mode among exhibition organisers and museum professionals. The thesis then charts the history of the period room in the context of three metropolitan museums – the Otago Early Settlers Museum, the Canterbury Museum, and the Dominion Museum – looking at the physical changes that were made to these displays over time, the attitudes that informed these changes, and the role that period rooms play in these institutions today.</p>

Immersive 5G Virtual Reality Visualization Display System Based on Big-Data Digital City Technology

The virtual reality visual display system creates a realistic virtual product display system, allowing users to swim in a three-dimensional virtual environment and perform interactive operations, fully simulating the process of shopping selection and payment in reality, so that users have an immersive feeling. The purpose of this article is to realize the design of an immersive 5G virtual reality visual display system through big-data digital city technology. This paper uses big-data digital city technology to design and implement an immersive virtual reality visualization system from the three-dimensional display mode of vision, hearing, and touch, creating a real and interactive three-dimensional visualization environment for users to have a more intuitive visual experience. The experimental results of this paper show that the smoothness of the virtual reality visualization system test can reach 60FPS, the excellent rate reaches nearly 33%, and the model scene-realistic feedback excellent rate is about 62.5%.

Pengembangan Learning Materials untuk E-learning Mata Kuliah Metodologi Penelitian

This development aims to produce a product in the form of learning materials for e-learning of Educational Research Methodology Course. The developed learning materials refer to the needs of the course and semester learning design that has been developed for the course, to facilitate learner in making more flexible and directed learning process. Development is carried out by Integrative Learning Design Framework Model with its three steps, they are, exploration information, enactment, and evaluation. The learning materials have gone through evaluation phase involving media experts, subject matter expert, instructional design expert, and users. Evaluation was carried out using open questionnaires to obtain descriptive data in the form of suggestions and input for product improvement. The follow up of the evaluation phase is some revisions of the product which include: color an text readability of the entire course site, changes in material display mode, formulation of learning objectives, concept map somponents, and learning object components.

Further Comparison of 4 Display Modes for a Multi-Resolution Foveated Laparoscope

Background. To overcome field of view and ergonomic limitations of standard laparoscopes, we are developing a multi-resolution foveated laparoscope (MRFL), which can simultaneously obtain both wide- and zoomed-in-view images. To facilitate the effectiveness of our MRFL, we have been investigating various ways of organizing and visualizing dual-view multi-resolution images acquired by the MRFL. In our prior study, we implemented and compared 6 display modes for the MRFL, assuming a typical clinical environment where a standard (but limited) resolution monitor is available. To take full advantage of our MRFL, displays having sufficient screen resolutions might be advantageous. The present study aims to further understand the effects of view configurations through displays with a standard high-definition (HD) resolution and a 4K resolution. In this study, we compare 3 display modes for limited-resolution displays against a new mode for sufficient-resolution displays. Methods. Twenty subjects performed 3 evaluation trials of a touching task with each display mode in an emulated MRFL environment. Various objective measurements including task completion time and the number of collisions, and subjective preference were recorded. Results. The new mode showed a better task completion time than the other modes, while it maintained a low number of collisions similar to the others. Moreover, the majority of participants selected the new mode as their most preferred one. Conclusions. With a sufficient display resolution, the co-registration between the unblocked and unwarped wide context view and the high-resolution zoomed-in view offered by the new mode was highly effective on both task performance and user preference.

Digital images and in-person evaluation of Anthurium ‘Tropical’ postharvest quality

Accurate quality classification is one of the requirements of the flower market, which is becoming increasing more sophisticated and demanding. However, there is a lack of information regarding how such classification is performed, and it is often conducted in a less empirical and more subjective way. Therefore, this work aimed to compare the efficiency of personal classification (in-person) and using digital images to determine the quality of anthurium cv. Tropical (Anthurium andraeanum Lind.). Three experiments were performed regarding the recording of the images and the display mode of the images and comparing three methods of classifying postharvest quality of anthurium. It was concluded that measurements of colorimetric parameters can be performed anywhere on the spathe, but the period in which the parameters are measured does affect. Evaluators differ in the thoroughness with which they assign grades, and there is no need for prior knowledge to assess quality using images. The L* parameter measured by the colorimeter presented higher correlation with the evaluation of postharvest quality of Anthurium andraeanum Lind. ‘Tropical’. Classification by images can be performed using different electronic devices, and in-person classification is more rigorous than classification conducted using digital images.
