Antinociceptive and anti-inflammatory effects of roots extracts from Actinidia arguta (Sieb.et Zucc.) Planch

Aims: The roots of Actinidia arguta (Sieb. et Zucc.) Planch (also named tengligen) have medicinal uses as anti-tumour, antinociceptive, and anti-inflammatory agents. In this study, we evaluated the antinociceptive and anti-inflammatory effects of 95% ethanol extract and different fractions of the roots of A. arguta (Sieb.et Zucc.) Planch (Tengligen). Methods: Three conventional methods were used to carry out the antinociceptive effect: acetic acid-induced abdominal writhing, formalin induced hind paw licking, and hot plate test. In addition, the anti-inflammatory effect was investigated by carrageenan-induced paw edema in rats. Conclusion: From the obtained results, we found that the total ethanol extract, ethyl acetate fraction, and n-butanol fraction all significantly inhibited acetic acidinduced writhing and both phases of the formalin induced pain response, increased the time of response to thermal stimulation in hot plate test, and exhibited significant dose-related inhibition of carrageenan induced paw edema volumes when compared with the control group. Based on our findings, we conclude that the flavonoid and saponin contents of tengligen are responsible for the antinociception and anti-inflammatory effects of Actinidia arguta (Sieb. et Zucc.) Planch, respectively.
BalloonFAB: Digital Fabrication of Large-Scale Balloon Art

We propose an interactive system that allows common users to build large-scale balloon art based on a spatial augmented reality solution. The proposed system provides fabrication guidance to illustrate the differences between the depth maps of the target three-dimensional shape and the current work in progress. Instead of using color gradients for depth difference, we adopt a high contrast black and white projection of the numbers in considering balloon texture. In order to increase user immersion in the system, we propose a shaking animation for each projected number. Using the proposed system, the unskilled users in our case study were able to build large scale balloon art.
Crushed it!: Interactive Floor Demonstration

We introduceCrushed It! , an interactive game on a sensor floor. This floor is combined with a multiple projector system to reduce occlusions from players' interactions with the floor. Individual displays, an HTC Vive to track player position, and smart watches were added to provide an extra layer of interactivity. We created this interactive experience to explore collaboration between people when interacting with large displays. We contribute a novel combination of different technologies for this game system and our studies showed this game is both entertaining and provides players with motivation to stay physically active. We believe presenting at interactivity would be a benefit to both our research and to the attendees of CHI 2019.
Augmented Visuotactile Feedback Support Sensorimotor Synchronization Skill for Rehabilitation

Augmented visual-audio feedback supports rhythmic motor performance in both sports training and sensorimotor synchronization practise. In home-based rehabilitation for minor stroke patients, training on a fine motor skill using rhythms not only helps to recover sophisticated motion ability but also increases their confidence and mental health recovery. Auditory information has been shown to have advantages for improving rhythmic motion performance, but it can be masked by environmental noise and may be intrusive to non-stakeholders. Under these circumstances, patients may be reluctant to practice actively due to difficulties hearing the auditory stimuli or through a concern for disturbing others. To address this issue, we explored an inconspicuous way of providing vibrotactile feedback through wristband. In order to investigate the general feasibility of a sensorimotor synchronization task, we conducted a preliminary user study with 16 healthy participants, and compared the visual-tactile feedback with visual-audio, visual-audio-tactile and visual-only feedback. Results showed that rhythmic motion accuracy with visual-tactile feedback has the equivalent facilitatory effect with visual-audio feedback. In addition, visual-tactile feedback supports smoother movements than the visual-audio feedback. In the future, after refinement with stroke patients, the system could support customization for different levels of sensorimotor synchronization training.
E-government: What Is It, and Will It Transform Government?

Like many trends that influence public policy andadministration, ‘e-government’ is a multifaceted andnebulous idea, easily applied to a range of differentsituations, across the entire gamut of government andsociety, and with differing intentions. There are wide-ranging claims made for e-government, considerablehopes pinned on it, and substantial commitments –financial and otherwise – made to it. The concept hasbeen embraced by political leaders; it is being used todrive changes to the public sector, and to legitimiseinvestment of public money in information andcommunications technology (ICT). An importantquestion, however, is what ‘e-government’ is, and whatshape an ‘e’ government might have. This articleoverviews the concept, the developmental phases ofe-government and some international and local policydevelopments, and speculates on the impact of ICT onthe future shape of government.
Designing Personalities of Conversational Agents

Recent years have seen numerous attempts to imbue conversational agents with marked identities by crafting their personalities. However, the question remains as to how such personalities can be systematically designed. To address this problem, this paper proposes a conceptual framework for designing and communicating agent personalities. We conducted two design workshops with 12 designers, discovering three dimensions of an agent personality and three channels to express it. The study results revealed that an agent personality can be crafted by designing common traits shared within a service domain, distinctive traits added for a unique identity, and neutral traits left intentionally undecided or user-driven. Also, such a personality can be expressed through how an agent performs services, what contents it provides, and how it speaks and appears to be. Our results suggest a renewed view of the dimensions of conversational agent personalities.
Phenotypic and Genotypic Characterization of Orthotopic Human Glioma Models and Its Relevance for the Study of Anti‐glioma Therapy

Most human gliomas are characterized by diffuse infiltrative growth in the brain parenchyma. Partly because of this characteristic growth pattern, gliomas are notorious for their poor response to current therapies. Many animal models for human gliomas, however, do not display this diffuse infiltrative growth pattern. Furthermore, there is a need for glioma models that represent adequate genocopies of different subsets of human gliomas (e.g., oligodendrogliomas). Here, we assessed the intracerebral growth patterns and copy number changes [using multiplex ligation‐dependent probe amplification (MLPA)/comparative genomic hybridization (CGH)] of 15 human glioma lines in nude mice. Most xenografts present with compact growing lesions intracerebrally. Only the E98 and, to a lesser degree, E106 xenograft lines (propagated through subcutaneous growth) consistently produced intracerebral tumors, displaying diffuse infiltrative growth in the brain parenchyma. In contrast, four xenograft lines (E434, E468, E473 and E478), established by direct intracerebral inoculation of human glioma cells and serially propagated intracerebrally, consistently showed extensive diffuse infiltration throughout the brain. After several passages, the neoplastic cells still carry typical chromosomal aberrations [(−1p/−19q in oligodendroglioma, +7/−10 in glioblastoma multiforme (GBM)]. Especially these latter four models and the E98 line thus represent adequate geno‐ and phenocopies of human gliomas and form an attractive platform to investigate different therapeutic approaches in a preclinical setting.
Flow: Towards Communicating Directional Cues through Inflatables

Current research in wearable technologies have shown that we can use real-time tactile instructions to support the learning of physical activities through vibrotactile stimulation. While tactile cues based on vibration may indicate direction, they do not convey the direction of movement. We would like to propose the use of inflatables as an alternative form of actuation to express such information through pressure. Inspired by notions from embodied interaction and somaesthetic design, we present in this paper a research through design (RtD) project that substitutes directional metaphors with push against the body. The result, Flow, is a wearable designed to cue six movements of the wrist/forearm to support the training of elementary sensory-motor skills of physical activities, such as foil fencing. We contribute with the description of the design process and reflections on how to design for tactile motion instructions through inflatables.
An Extended Relational Data Model for Multimedia DBMSs

We have extended the canonical relational data model to enable the management of multimedia objects. In an attempt to provide a smooth paradigm shift to multimedia information system development, we have enhanced the relational data model framework with techniques for modeling, storing and manipulating multimedia data. In particular, we have provided a graphical conceptual model for structuring a multimedia document and mapping rules for translating it into an extended relational data schema. Extensions have regarded the management of foreign keys, active components, mechanisms for the management of spatial and temporal relations, and finally functions for handling multimedia presentations. As a consequence, we have also provided extensions to the SQL language to handle these new mechanisms.
Weaving the Topics of CHI: Using Citation Network Analysis to Explore Emerging Trends

This paper provides a comprehensive and novel analysis of the annual conference proceedings of CHI to explore the structure and evolution of the community. Self-awareness is healthy for a diverse and dynamic community, allowing it to anticipate and respond to emerging themes. Instead of using a traditional topic modelling approach to analyze the text of the papers, we adopt a social network analysis approach by analyzing the citation network of papers. After constructing such a citation network, community detection is applied in order to cluster papers into different groups. The keywords of these groups are found to represent different research themes in human-computer interaction, while the growth or decline of these groups is visualized by their paper shares over time. Lastly, we contribute a visualization tool for exploring emerging trends within our community, which can be used to predict likely topics at future CHI conferences.
A Case of Atopic Dermatitis Co-existing with Psoriasis Vulgaris

The coexistence of atopic dermatitis (AD) and psoriasis has been not impossible, because their respective immunological situations involve distinct reactions. Recently, there are some reports of comorbidity of AD and psoriasis. Here we present the case of a patient with AD who developed psoriasis. A 43-year-old female developed AD, and new erythema has increased over 40 years. The results of skin biopsy showed psoriasis-form changes. We started to treat her using cyclosporine, second-generation anti-histamine tablets, steroid ointments, and Dovobet® ointment under a diagnosis of AD with psoriasis. Now we treat her using narrow-band UVB phototherapy and steroid ointments. Her skin condition is under good control. Further investigation is needed on the pathogenesis and immunological situation of the coexistence of AD with psoriasis.
Gender Effects on Collaborative Online Brainstorming Teamwork

It is common for individuals with diverse demographic backgrounds to collaborate through computer-mediated communication (CMC) technologies. Groups with internal diversity are typically considered to be advantageous to group performance due to the presence of different perspectives and the potential to stimulate new ideas. However, intergroup conflicts can also occur in diverse groups, especially for groups with imbalanced composition. Previous studies have pointed out that minority members often suffer from unequal participation and performance pressure, which may further decrease group outcome. Since CMC tools facilitate online collaboration, it is necessary to understand how group composition interacts with the affordances of CMC tools on group collaboration. In this study, we tested three gender compositions (female-majority, equal-gender-composition, male-majority) with two communication contexts (video-text, text-only) and found that both gender composition and communication medium influenced group collaboration. Design implications for online collaboration are provided based on our findings.
Emojilization: An Automated Method For Speech to Emoji-Labeled Text

Speech To Text (STT) plays a significant role in Voice User Interface (VUI). While preserving necessary semantic information in converted text, STT generally captures no or limited emotional information. In this paper, we present an emojilization tool to automatically attach related emojis to the STT-generated texts by analyzing both textual and acoustic features in speech signals. For a given voice message, the tool selects the most representative emoji from 64 most commonly used emojis. We conducted a pilot study with 34 participants. In our study, 159 utterances were labeled with emojis by our tool. The emotion restoration effect was evaluated. The results indicate that the proposed tool effectively compensates for the emotion loss.
Sea Surface Ka-Band Doppler Measurements: Analysis and Model Development

Multi-year field measurements of sea surface Ka-band dual-co-polarized (vertical transmit–receive polarization (VV) and horizontal transmit–receive polarization (HH)) radar Doppler characteristics from an oceanographic platform in the Black Sea are presented. The Doppler centroid (DC) estimated using the first moment of 5 min averaged spectrum, corrected for measured sea surface current, ranges between 0 and ≈1 m/s for incidence angles increasing from 0 to 70 ∘ . Besides the known wind-to-radar azimuth dependence, the DC can also depend on wind-to-dominant wave direction. For co-aligned wind and waves, a negative crosswind DC residual is found, ≈−0.1 m/s, at ≈20 ∘ incidence angle, becoming negligible at ≈ 60 ∘ , and raising to, ≈+0.5 m/s, at 70 ∘ . For our observations, with a rather constant dominant wave length, the DC is almost wind independent. Yet, results confirm that, besides surface currents, the DC encodes an expected wave-induced contribution. To help the interpretation, a two-scale model (KaDOP) is proposed to fit the observed DC, based on the radar modulation transfer function (MTF) previously developed for the same data set. Assuming universal spectral shape of energy containing sea surface waves, the wave-induced DC contribution is then expressed as a function of MTF, significant wave height, and wave peak frequency. The resulting KaDOP agrees well with independent DC data, except for swell-dominated cases. The swell impact is estimated using the KaDOP with a modified empirical MTF.
Prevalence of human papillomavirus infection in women in Busan, South Korea

To investigate the prevalence of and the risk factors for human papillomavirus (HPV) infection in South Korea, we interviewed and examined a randomly selected sample of 863 sexually active women (age range = 20–74 years, median 44) and 103 self‐reported virgins from Busan. The presence of DNA of 34 different HPV types in cervical exfoliated cells was tested among sexually active women by means of a PCR‐based assay. IgG antibodies against L1 virus‐like particles (anti‐VLPs) of HPV types 16, 18, 31, 33 and 58 were also evaluated by means of ELISA. The overall prevalence of HPV DNA was 10.4% (95% confidence interval, CI: 8.5–12.7%). The most often found HPV DNA types were HPV 70, HPV 16 and HPV 33; 19.8% (95% CI: 17.2–22.0) of sexually active women had antibodies against one or more HPV types. The most common anti‐VLPs were against HPV 18, 31 and 16. Prevalences standardized by age on the basis of the world standard population were 13.0% for HPV DNA and 17.1% for anti‐VLPs. The concordance between the 2 HPV markers at an individual level was modest, but the risk factors for detection of HPV DNA and anti‐VLPs were similar: number of lifetime sexual partners (odds ratio, OR for ≥ 4 vs. 1 = 3.5 and 5.4, respectively), seropositivity for herpes simplex virus‐2 antibodies (OR = 2.6 and 2.5, respectively) and being single or divorced. HPV DNA, but not anti‐VLPs, were elevated among women whose husbands were thought by their wives to have extra‐marital affairs and those who had undergone vasectomy. Among 103 virgins, 4.9% had anti‐VLPs (1/73 among those aged 24 years or less). © 2002 Wiley‐Liss, Inc.
SIGCHI Outstanding Dissertation Award: A Quantified Past

A 'data-driven life' has become an established feature of present and future technological visions. This dissertation interrogates the human experience of a data-driven life, by conceptualising, investigating, and speculating about personal informatics tools as new technologies of memory. I argue that the prevalence of quantified data and metrics is creating fundamentally new and distinct records of everyday life: a 'quantified past'. To address this, I conducted qualitative and idiographic fieldwork -- with long-term self-trackers, and subsequently with users of 'smart journals' -- to investigate how this data-driven record mediates the experience of remembering. Further, I undertook a speculative and design-led inquiry to explore the context of a 'quantified wedding'. Adopting a context where remembering is centrally valued, this Research through Design project demonstrated opportunities for the design of data-driven tools for remembering. Crucially, while speculative, this project maintained a central focus on individual experience, and introduced an innovative methodological approach 'Speculative Enactments' for engaging participants meaningfully in speculative inquiry.
Using Gameplay Design Patterns to Support Children's Collaborative Interactions for Learning

Co-located games that bring players together have strong potential for supporting children's collaborative competencies. However, there is a challenge how to make results from research work related to this within Child-Computer Interaction (CCI) field easily transferable to future CCI research. Pursuing this challenge, we combined levels of Collaborative Activity (CA) with the design tool gameplay design patterns (GDPs). This combination was used to support comparative play tests of a co-located game with children who have learning difficulties. We report our observations on using our approach, arguing that the possibility of making patterns based on CA concepts such as Reflective Communication points towards collaborative GDPs. Furthermore, this study presents an exemplar that as a flexible and extensible tool GDPs can be used with different theories and models in the CCI field.
Modeling requirements for combinatorial software testing

The combinatorial approach to software testing uses models to generate a minimal number of test inputs so that selected combinations of input values are covered. The most common coverage criteria is two-way, or pairwise coverage of value combinations, though for higher confidence three-way or higher coverage may be required. This paper presents example system requirements and corresponding models for applying the combinatorial approach to those requirements. These examples are intended to serve as a tutorial for applying the combinatorial approach to software testing. Although this paper focuses on pairwise coverage, the discussion is equally valid when higher coverage criteria such as three-way (triples) are used. We use terminology and modeling notation from the AETG1 system to provide concrete examples.
Signal processing techniques for natural sleep posture estimation using depth data

Several efforts are being made in studying sleeping posture of a person under natural conditions without causing discomfort. In this study, various methods are proposed and explored in which features defining sleep postures of a person are investigated for intelligent pattern recognition. Using the measured depth data, three dimensional depth scans as well as the cross-sectional scans of the static sleeping body are captured. 1D Fast Fourier Transforms are used as complementary feature of the cross-sectional scans in pattern recognition. Due to better orientation-frequency characteristics, the two dimensional Gabor filter banks are also applied on depth images to produce Gabor images from which features known as Gabor features can be extracted. These selected features can be further integrated as a part of natural sleep posture recognition.
Demonstration of Springlets: Expressive, Flexible and Silent On-Skin Tactile Interfaces

We present Springlets, expressive, non-vibrating mechanotactile interfaces on the skin. Embedded with shape memory alloy springs, we implement Springlets as thin and flexible stickers to be worn on various body locations, thanks to their silent operation even on the neck and head. We present a technically simple and rapid technique for fabricating a wide range of Springlet interfaces. We developed six modular Springlets: a pincher, a directional stretcher, a presser, a puller, a dragger, and an expander (Fig. 1). In our hands-on demonstration, we show our modular Springlets and several Springlet interfaces for tactile social communication, physical guidance, health interfaces, navigation, and virtual reality gaming. Attendees can wear the interfaces and explore their expressive variable force profiles and spatiotemporal patterns.
The Continued Prevalence of Dichotomous Inferences at CHI

Dichotomous inference is the classification of statistical evidence as either sufficient or insufficient. It is most commonly done through null hypothesis significance testing (NHST). Although predominant, dichotomous inferences have proven to cause countless problems. Thus, an increasing number of methodologists have been urging researchers to recognize the continuous nature of statistical evidence and to ban dichotomous inferences. We wanted to see whether they have had any influence on CHI. Our analysis of CHI proceedings from the past nine years suggests that they have not.
Techniques to improve Bluetooth performance in interference environments

Bluetooth is a radio technology for wireless personal area networks operating in the 2.4 GHz ISM band. Since both Bluetooth and IEEE 802.11 devices use the same frequency band and may likely come together in a laptop or may be close together at a desktop, interference may lead to significant performance degradation. The main goal of this paper is to propose solutions to the interference problem consisting of power control adjustments and scheduling policies to be implemented by the Bluetooth device. Simulation results are given for selected scenarios and configurations of interest.
LUNE: Representing Lunar Day by Displayed Lighting Object

LUNE is a displayed lighting object representing time. It provides real-time lighting visualized moon phase. People can recognize the date of month through abstract image of moon. This product was developed to investigate the use of metaphor from lighting to represent time. A diverse set of researches and design initiatives related to time, temporality and slowness has emerged in the DIS and HCI communities. An important area of work is to represent time. The primary objective of this research is to suggest the new perspective of time called sense of time. First, we can understand how people perceive the time and we can also trace recent research related to perspectives of time in HCI. Second, we designed artifacts and investigated the use of moon phase as material to represent time in a new approach.
