Can Unhappy Pictures Enhance the Effect of Personas? A User Experiment

There has been little research into whether a persona's picture should portray a happy or unhappy individual. We report a user experiment with 235 participants, testing the effects of happy and unhappy image styles on user perceptions, engagement, and personality traits attributed to personas using a mixed-methods analysis. Results indicate that the participant's perceptions of the persona's realism and pain point severity increase with the use of unhappy pictures. In contrast, personas with happy pictures are perceived as more extroverted, agreeable, open, conscientious, and emotionally stable. The participants’ proposed design ideas for the personas scored more lexical empathy scores for happy personas. There were also significant perception changes along with the gender and ethnic lines regarding both empathy and perceptions of pain points. Implications are the facial expression in the persona profile can affect the perceptions of those employing the personas. Therefore, persona designers should align facial expressions with the task for which the personas will be employed. Generally, unhappy images emphasize realism and pain point severity, and happy images invoke positive perceptions.

Assessing Early Stage Design Sketches and Reflections on Prototyping

Designers routinely create informal “thinking” sketches to explore a design space, “talking” sketches to communicate design ideas during the early phases of the design process, and “learning” prototypes to test potential concepts. This study presents two new tools to assess novice designers' sketch attributes and prototyping reflections in the context of an introductory design course. First, it proposes a rubric for assessing the quality of early stage design sketches including line smoothness, proportion, and understandability. Of particular note is the contribution of assessing understandability as a metric for sketches as communication tools. This study also presents a tool to capture designer reflections after each iteration of a prototype. Not only does this record what is learned about a design, but also personal and emotional reactions to the process. Sketching-related results show a positive correlation between sketch quality and understandability, indicating the importance of sketch quality especially when designers use sketches to communicate. Results also indicate that early stage sketch quantity, but not quality, is linked with design outcomes. The study also finds a link between frequency of sketching and higher maximum sketch quality scores (i.e. at least one excellent sketch) as well as a correlation between individuals' maximum sketch quality scores and overall design outcomes. Preliminary results around prototyping indicate that reflection on both the technical and emotional aspects of prototyping may be a worthwhile area of further study. Finally, several results point to novice designers' lack of consistent focus on users in their prototyping reflections and presentations.

Research Progress of Bonding Agents and Their Performance Evaluation Methods

Bonding agents are an important type of additive that are used to increase the interfacial interaction in propellants. A suitable bonding agent can prevent the dewetting between the oxidant and binder, and thus effectively improve the mechanical properties of the propellant. In the current paper, the bonding mechanisms and research progress of different types of bonding agents such as alcohol amine bonding agents, borate ester bonding agents, aziridine bonding agents, hydantoin bonding agents, neutral polymer bonding agents, and so on, are reviewed and discussed. The evaluation methods of their bonding performances including molecular dynamic simulation, contact angle method, in situ loading SEM, characterization analysis, and mechanical analysis are summarized to provide design ideas and reference for future studies.

APPLICATION OF DIGITAL STRUCTURE SIMULATION AS A TOOL FOR THE EXPLORATION OF WIDE SPAN STRUCTURE IDEAS

Review on structure behaviour and visual appearance of a building is needed in generating creativity in the making of an architectural design. The use of any specific structure software will facilitate this in the process. This research aims to prove the effectiveness with which designers can compose alternative forms of architectural appearance through the use of the software. One of the tools in the creative process used in the exploration of 2-dimensional frame structures is DR FRAME. The observations were carried in the Structure and Construction IV Studio at Itenas Architecture Study Program Bandung through a digital simulation using DR. FRAME software demo version. Several students are invited to explore various forms of wide-span truss structures at the level of unified integration. The results through the program execution show various diagrams which can be implemented in the design of the form and the type of structural components. DR.FRAME software enriches ideas in the wide-span structure design which provides an understanding of the relationship between structural behaviour and the appearance of architectural design. The use of other supporting software is supposed to be applied as an alternative search for various structural design ideas for architecture students

A Conceptual Framework to Improve the Symbol Implementation of 4D Printing Communication between Designers and Engineers

This research investigates the communication barriers between designers and engineers in designing 4D Printing parts. We have proposed a conceptual design framework for 4D Printing symbols as the communication tool. Then, we have recruited sixty-fifty designers and engineers who participated in our online experiments. The focus of the online survey is to find out how designers and engineers understand reciprocal communication by using the proposed symbols. Our results showed that 85% of participants could understand the 4D Printing symbols correctly. The study concludes that using the conceptual framework can help designers and engineers communicate 4D Printing element information and stimulate design ideas effectively.

Taoist Culture Design: The Development of the Design Ideas

The cultural development of “Tao” and “Qi” has lasted for thousands of years. The theory of “Tao” began with Laozi and Zhuangzi. Through “The Book of Changes · Xici,” it is developed as “the metaphysical is the Tao, and the figurative is the Qi [1]”. “Tao” and “Qi” are interdependent as philosophical concepts. It first guided the philosophy of Taoism, Confucianism and other scholars in the pre-Qin period, and then promoted the development of national system in Xia, Shang and Zhou Dynasty, which gave birth to the aesthetic system of the ancient imperial court. With the development of modern design ideas, the design ideas of “Tao” and “Qi” are integrated. After thousands of years of civilization development and technological changes, today’s ideas of “Tao” and “Qi” are booming, and have in-depth exchanges and integration with foreign cultures.

Ferroptosis-Inducing Nanomedicine for Cancer Therapy

Ferroptosis, a new iron- and reactive oxygen species–dependent form of regulated cell death, has attracted much attention in the therapy of various types of tumors. With the development of nanomaterials, more and more evidence shows the potential of ferroptosis combined with nanomaterials for cancer therapy. Recently, there has been much effort to develop ferroptosis-inducing nanomedicine, specially combined with the conventional or emerging therapy. Therefore, it is necessary to outline the previous work on ferroptosis-inducing nanomedicine and clarify directions for improvement and application to cancer therapy in the future. In this review, we will comprehensively focus on the strategies of cancer therapy based on ferroptosis-inducing nanomedicine currently, elaborate on the design ideas of synthesis, analyze the advantages and limitations, and finally look forward to the future perspective on the emerging field.

Designing for others: the roles of narrative and empathy in supporting girls’ engineering engagement

Purpose Science museums provide a context for developing and testing engineering activities that support visitors in creating personally meaningful objects. This study aims to propose that narrative design elements in such engineering activities can foster empathy to support engineering engagement among girls ages 7–14. Design/methodology/approach Taking a constructionist approach to engineering design, the authors present results from an observational study (n = 202 girls) of engineering activities across three museums that were designed to foster girls’ engineering engagement by integrating narrative elements aimed to foster empathy in activities. Using quantitative counts from observation protocols, the authors conducted statistical analyses to explore relationships between narrative, engineering and empathy. Findings Linear regression demonstrated a statistically significant relationship between empathy and increased numbers of engineering practices within museum activities. Additionally, this led us to explore the impacts the potential narrative design elements may have on designing for empathy – multiple linear regressions found both narrative and empathy to be independently associated with engineering practices. Overall, the authors found that using narrative to design activities to elicit empathy resulted in girls demonstrating more engineering practices. Originality/value The authors offer design ideas to foster aspects of empathy, including user-centered design, perspective-taking, familiarity and desire to help.

CONCEPTUAL DESIGN. STAGES OF FORMATION

Conceptual design is the most creative part of architectural activity. In the professional work of architects, conceptual design is given great importance. Various architectural and design forums, exhibitions, competitions are dedicated to him. In Soviet times, an interesting example of the formation of conceptual solutions is the work of Alexander Brodsky and Ilya Utkin (who signed their works as a tandem of "Brutus"). We have other solutions of interesting concepts - the object of the competition "The World of El Lysytsky" - the Globe Theater in Novosibirsk. Here the authors start from the main idea - that the cube is the main form that characterizes the spirit and style of the Russian avant-garde of the twentieth century. Conceptual design ideas are implemented in the construction of unusual hotels, atypical urban environment, non-traditional building materials. All this allows you to think about life according to other rules. Than those prescribed in building codes. The world around us is more interesting and diverse, so we can, in part, paint it in bright colors.

St James and the Good Shepherd: windows on the landscape

Two New Zealand churches completed in the 1930s, St James' Church at Franz Josef/Waiau (James Stuart Turnbull and Percy Watts Rule, 1931) and the Church of the Good Shepherd on the shores of Lake Tekapo (Richard Strachan De Renzy Harman, 1935), feature large plate glass windows behind the altar, affording expansive views of the natural landscape beyond. This represented a significant departure from prevailing ecclesiastical design ideas of the time, with the interior of the churches being intimately connected to the landscape outside, rather than the usual largely internalized atmosphere with any sense of the surroundings limited to light coming through strategically placed decorative or stained-glass windows. It is, however, a design aesthetic that has seldom been utilized in New Zealand since. This paper traverses the history and design of the two churches and their relationships with the landscapes in which they are situated, and concludes that St James' Church provides a heightened religious experience and is a more successful metaphor for the Christian journey.
