BACKGROUND Electronic health record information systems' continuous application has accumulated enormous medical data with potential value. Semantic interoperability is the premise of mining and realizing these values by sharing and reusing vast scattered, heterogeneous, and multi-source clinical data. Several initiatives have been developing information models to realize and improve semantic interoperability, among which the openEHR model is one of the outstanding information models. Reusing archetypes from Clinical Knowledge Manager (CKM) instances is the backbone of achieving semantic interoperability based on the openEHR approach. Archetype reuse among different CKMs is of great significance to achieve a broader range of semantic interoperability. However, the reuse of archetypes among different existing CKMs is still unclear. OBJECTIVE This study aims to investigate the reuse of openEHR archetypes across the CKMs approved by openEHR International for achieving and improving semantic interoperability. METHODS This study analyzes and compares archetype reuse across the given five CKMs (Fi-CKMs) and across the four CKMs (Fo-CKMs), respectively. Firstly, the analysis and comparison of reused archetypes are executed in terms of: archetype reuse number and archetype reuse ratio. Then, data elements of the given 25 reused archetypes were analyzed and compared across the Fi-CKMs and across the Fo-CKMs, including the type, number and ratio of the reused data elements. RESULTS The archetype reuse numbers across the Fi-CKMs and the Fo-CKMs are 25 and 58, respectively. Comparison of archetype reuse ratio showed that reducing one CKM increased the archetype reuse ratio from 5.56% - 19.23% to 12.89% - 44.62%. The analysis and comparison of data elements across the Fi-CKMs and the Fo-CKMs show that reducing one CKM increased the reusable data elements from 231 to 355, increased the data element reuse ratio from 54.20% - 70.64% to 90.33% - 100%, and increased the data element direct ratio from 89% to 100%. CONCLUSIONS A large number of archetypes have been accumulated in the existing CKM instances, which provides an important foundation for the reuse of archetypes needed for semantic interoperability. With the decrease of the involving person, archetype reuse is improved, including the number of the reused archetype, the number of data element reuse, and the ratio of data element direct reused. A more effective coordination mechanism between multiple CKMs needs to be established to promote archetypes reuse across CKMs.

Female Experience

The essay examines the texts of the two women writers - Leila Abouzeid (from Morocco) and Nawal El Saadawi (from Egypt) - as offering two female perspectives within what is commonly referred to as "feminine" writing in the Arab Muslim world. My main interest is to explore the various discursive articulations of female identity that are challenged or foregrounded as a positive model. The essay points to the serious pitfalls of some feminist narratives in Arab-Muslim societies by dealing with a related problem: the author's setting up of convenient conceptual dichotomies, which account for the female experience, that reduce male-female relationships in the given social context to a fundamentally antagonistic one. Abouzeid's novel will be a case study of a more positive but also realistic and complex perspec­tive on female experience ...

Efficient Data

Over the last decade, a 3D reconstruction technique has been developed to present the latest as-is information for various objects and build the city information models. Meanwhile, deep learning based approaches are employed to add semantic information to the models. Studies have proved that the accuracy of the model could be improved by combining multiple data channels (e.g., XYZ, Intensity, D, and RGB). Nevertheless, the redundant data channels in large-scale datasets may cause high computation cost and time during data processing. Few researchers have addressed the question of which combination of channels is optimal in terms of overall accuracy (OA) and mean intersection over union (mIoU). Therefore, a framework is proposed to explore an efficient data fusion approach for semantic segmentation by selecting an optimal combination of data channels. In the framework, a total of 13 channel combinations are investigated to pre-process data and the encoder-to-decoder structure is utilized for network permutations. A case study is carried out to investigate the efficiency of the proposed approach by adopting a city-level benchmark dataset and applying nine networks. It is found that the combination of IRGB channels provide the best OA performance, while IRGBD channels provide the best mIoU performance.

Heritage Interpretation

AbstractHolistic interpretation of Earth heritage is one of the most important tasks of UNESCO Global geoparks. The ABC (abiotic, biotic, and cultural interconnections) concept is a potential interpretive approach used in Earth heritage popularization through geotourism. Apart of the deeper understanding of this concept, this study explores the application of this concept in selected geoparks. The Colca and Volcanoes Andagua UNESCO Global Geopark (Peru) and Muroto UNESCO Global Geopark (Japan) served as a case study in the frame of this qualitative research conducted during the summer 2019. Results show that the ABC approach is nearly perfectly understood by both geoparks, however there are both internal and external factors which influence the extent and form of how this concept is applied in practice. Except for specific geographical settings, different stages of geopark product development, and different managerial approaches, they mainly include the level of scientific knowledge and general education in the given geopark, as well as level of knowledge management and networking with another UNESCO global geoparks. The more experienced Muroto Geopark interpretation exhibits a comparatively higher level of visible ABC application, while the Colca and Volcanoes Andagua Geopark can benefit in the future from the natural inclination and ability of the local people to integrate the cultural aspects into their Earth heritage interpretation.

Component Repository

Context-aware systems are able to monitor and automatically adapt their operation accordingly to the execution context in which they are introduced. Component-based software engineering (CBSE) focuses on the development and reuse of self-contained software assets in order to achieve better productivity and quality. In order to store and retrieve components, CBSE employs component repository systems to provide components to the system developers. This paper presents an active component repository that is able to receive the current configuration from the context-aware system and compute the components and the new architecture that better fit the given context. Since the repository has a wide knowledge of available components, it can better decide which configuration is more suitable to the running system. The repository applies Fuzzy logic algorithm to evaluate the adequacy level of the components and GRASP algorithm to mount the new system architecture. In order to verify the feasibility of our approach, we use a digital TV middleware case study to achieve experimental results.

Communication Operations

Data distributions are an abstract notion for describing parallel programs by means of overlapping data structures. A generic data distribution layer serves as a basis for implementing specific data distributions over arbitrary algebraic data types and arrays as well as generic skeletons. The necessary communication operations for exchanging overlapping data elements are derived automatically from the specification of the overlappings. This paper describes how the communication operations used internally by the generic skeletons are derived, especially for the asynchronous and synchronous communication scheduling. As a case study, we discuss the iterative solution of PDEs and compare a hand-coded MPI version with a skeletal one based on overlapping data distributions.

The article deals with the dynamics of the semantic complex of dominant units in poetic text. Units of poetic text are divided into constant and dominant ones. Constant units realize the function of the context formation. They have one clear meaning. Dominant units realize the function of semantization. They are poly-interpretative. The methodology of the work is based on the theory of intertextuality which is viewed from the position of structural, interpretative and lingua-cultural approaches. The brief typology and characteristics of intertextual relations are given: auto- (self-quotations, self-allusions), in- (quotations, allusions), para- (structural and compositional units of a text such as a title, an epigraph, etc.) and arch-textuality (genre imitation; referring to well-known artistic images or cultural phenomena). The paper presents the model of analysis of dominant units in poetic text. The analysis is carried out in five steps: fragmentation, contextual analysis, search and determination of intertextual relations between the analyzed unit and units of address texts, contextual analysis of address texts, synthesis of the obtained contextual meanings. The practical material under study is the poem Elegy by the Canadian poet L. Cohen. The unit of analysis is the personal pronoun he in the given poetic text. The paper establishes intertextual relations between Elegy and texts from Greek mythology, the Holy Bible, Christian culture, and other works by L. Cohen. The conducted analysis shows that intertextual relations between the studied units initiate exchange and superimposition of their context meanings. As a result, the studied unit can have several meanings (some of which are not present in dictionaries but unique for the given author) within the same context. In this way, the dynamics of the semantic complex of the studied units and poetic text is realized.

In this paper, we describe a case study of an undergraduate course on research methodology, in which lecture was reduced to a minimum and replaced with experiential learning activities. The course design was project-based and spiraled through four phases: a mini-lecture on a given research method, an “early practice” activity, and “reflection on practice” tutor-guided small group collaborations which led to deeper understanding of the given research method. This particular course design constitutes a paradigm shift in comparison to the predominant in Greek higher education didactic pedagogical model. How this paradigm shift was received and experienced by the participating students? In order to get rich insights into the lived experiences of the participants (N=15), we adopted a blended qualitative research approach: thematic analysis combined with students’ critical reflections on their experience, aiming to produce a thick description of our intervention. The course design and implementation positioned students and their tutors as knowledgeable actors able to contribute research insights through their transactions.

Background The semantic interoperability of health care information has been a critical challenge in medical informatics and has influenced the integration, sharing, analysis, and use of medical big data. International standard organizations have developed standards, approaches, and models to improve and implement semantic interoperability. The openEHR approach—one of the standout semantic interoperability approaches—has been implemented worldwide to improve semantic interoperability based on reused archetypes. Objective This study aimed to verify the feasibility of implementing semantic interoperability in different countries by comparing the openEHR-based information models of 2 acute coronary syndrome (ACS) registries from China and New Zealand. Methods A semantic archetype comparison method was proposed to determine the semantics reuse degree of reused archetypes in 2 ACS-related clinical registries from 2 countries. This method involved (1) determining the scope of reused archetypes; (2) identifying corresponding data items within corresponding archetypes; (3) comparing the semantics of corresponding data items; and (4) calculating the number of mappings in corresponding data items and analyzing results. Results Among the related archetypes in the two ACS-related, openEHR-based clinical registries from China and New Zealand, there were 8 pairs of reusable archetypes, which included 89 pairs of corresponding data items and 120 noncorresponding data items. Of the 89 corresponding data item pairs, 87 pairs (98%) were mappable and therefore supported semantic interoperability, and 71 pairs (80%) were labeled as “direct mapping” data items. Of the 120 noncorresponding data items, 114 (95%) data items were generated via archetype evolution, and 6 (5%) data items were generated via archetype localization. Conclusions The results of the semantic comparison between the two ACS-related clinical registries prove the feasibility of establishing the semantic interoperability of health care data from different countries based on the openEHR approach. Archetype reuse provides data on the degree to which semantic interoperability exists when using the openEHR approach. Although the openEHR community has effectively promoted archetype reuse and semantic interoperability by providing archetype modeling methods, tools, model repositories, and archetype design patterns, the uncontrolled evolution of archetypes and inconsistent localization have resulted in major challenges for achieving higher levels of semantic interoperability.
