Design Thinking for Sustainable Mascot Character Design
Authors: Fathoni Ahmad Faisal Choiril Anam
Published: May 2023

In the character licensing industry, we identify one use of a character brand in the shape of a mascot. A good design for a mascot in an institution, community, or specific event will increase the mascot and the institute's sense of belonging. In order for the mascot design to match the community's tastes, the appropriate formulation is required during the process of producing this mascot figure. As a result, it is vital to have a strategy that enables achieving this goal to be more manageable, which can be employed in creating different mascot designs. This research intends to build a formula based on design thinking to capture the target market's tastes, through a poll based on design elements and principles, in a case study of making the "We Love Design" event mascot from Bina Nusantara University. The baby Sumatran tiger was selected as the mascot's form because, in addition to carrying the most frequently selected features in the poll, it also embodies the local content of Indonesia to raise the sense of belonging. The fundamental contribution of this study is the innovation of a system that streamlines the process of developing a brand character, which in this case takes the form of a mascot. Two polls with 724 & 1,018 respondents were employed as the approach. The process used to create this mascot character design is expected to be used in other character designs, including mascots and character licenses to make it sustainable.

Authors: Afroh Happy Nihayatul , Basaria Fransisca Tiur
Published: May 2023

This study looks into the implementation of the HIRARC approach in five Indonesian construction companies in order to reduce risks to workers' health and the environment. Companies face increased pressure to maintain productivity as technology and manufacturing advance, which often results in a higher likelihood of worker injuries if they are not in compliance with OSHA regulations. To assess the effectiveness of the HIRARC technique, the study examines the companies' occupational health and safety, hazard identification, risk assessment, and risk control practices. Accidents continue to occur despite the companies' implementation of the approach, indicating the need for further development. As a result, the study recommends that OSHA management and construction workers receive HIRARC training and certification to reduce accidents and protect worker health and the environment. Implementing hazard identification and risk assessment methodologies can also assist construction firms in reducing environmental and public health risks, thereby promoting sustainable development. Overall, these findings emphasize the significance of implementing effective occupational health and safety practices in order to create a safer and healthier workplace.

Authors: Pramono Andi , Wijaya Ida Bagus Ananta
Published: May 2023

Candi Kidal represents a cultural heritage structure that should be preserved. This temple structure is similar to the other temples in that it contains a foot section (Bhurloka), a body part (Bhuvarloka), and a summit portion (Swarloka). Some reliefs are read on the body using the Prasawya technique, and a story about the loyalty of a child named Garudeya to his mother, Winata, will appear. The story of a son freeing his mother from slavery is analogous to the Indonesian people's battle for freedom from Dutch colonialism. This study intends to introduce Garudeya's intangible reliefs at Candi Kidal and explain the moral message they embody. The Garudeya relief found in the Candi Kidal will be re-displayed on a sitting lamp as part of this research. The author did a site survey, interviews, questionnaires, and a literature review in this study. The author used the ATUMICS approach to create a prototype in the form of a sitting lamp, which aids in transforming traditions into contemporary contexts. The main focus of this study is on the concept of form, which is the transformation of Candi Kidal's silhouette into the shape of a sitting lamp. Furthermore, the lithophane technique, which converts a photograph into a 3D relief, is used on the body of the sitting lamp. As a result, the relief seen on Candi Kidal's body can be reproduced on the sitting lamp's body.

The Transformation of Second-Hand Clothes Shopping as Popular Sustainable Lifestyle in Social Media Era
Authors: Oscario Angela
Published: May 2023

People's forced habit changes as a result of the epidemic have created a possibility for long-term human progress. The use of second-hand clothing, also known as "cimol," "awul-awul," "burjer," "babebo," and other terms, as well as other controversial local cultures, really promote sustainable living in Indonesia. However, because of their connection to poverty, these were traditionally avoided. For Gen Z, used clothing has been socially constructed as a new reality in large part thanks to social media. In order to understand how Gen Z's awareness and consideration of used clothing affects their purchase choices, this study combines qualitative and quantitative methodologies. Before purchasing used clothing, Gen Z considers sustainability, fashion style, pricing, and sanitation. Social media influencers externalize the qualities of used clothing, therefore it's crucial to express them symbolically to appeal to Gen Z's wants. Without lecturing Gen Z on what to do, but rather by presenting their own personal experiences and viewpoints, this study offers as a lesson on how to deconstruct an unpopular local culture and socially reconstruct it into a popular culture that encourages a harmonious interaction between humans and nature.

Authors: Corticeiro Sofia , Rodrigues Diana , Pinto Glória , Fonseca Carlos , Maia Paula
Published: May 2023

Natural regeneration is crucial to maintaining local adaptative genetic pools of Pinus pinaster Ait. forests and their restoration following disturbance events. After a wildfire, weak-serotinous maritime pine populations may only depend on the viability of seeds exposed to fire to recover. Subsequently, summer drought during the early stages of the pine seedlings may seriously jeopardize the success of natural regeneration and the productivity of natural exploitable forests. The main objectives of this work were 1) to determine and compare the seed germination rates of weak-serotinous maritime pine populations along a geographic gradient within the Coastal Center of Portugal and 2) to investigate the ability of non-selected natural regenerated pine seedlings to survive under water limitation conditions. To accomplish those aims, seeds were collected from 8 populations distributed along a 100 km geographical gradient and left to germinate for 2 months. The seedlings were submitted to a water limitation experiment for 3 weeks.

Overall no relation was found between seed weight and germination rate, but different trends were observed amongst populations. No relation was found between seed traits and seedling growth. Under water limitation, results suggested differences in water use efficiency between populations, possibly justified by adaptation to specific site conditions.
Fasting Plasma Glucose Levels at the Time of Admission Predict 90-Day
Mortality in Patients with Viral Pneumonia. A Prospective Study
Authors: Xu Jie , Zhao Jianyu , Wu Liyuan , Lu Xinxin
Published: May 2023

Purpose To determine the effect of fasting plasma glucose (FPG) level at
admission affects the 90-day mortality rate in patients with viral
pneumonia.

Methods Two hundred fifty viral pneumonia patients were stratified into
normal FPG (FPG<7.0 mmol/L), moderately-elevated FPG
(FPG=7.0–14.0 mmol/L), and highly-elevated FPG
groups (FPG≥14.0 mmol/L) according to the FPG level at
the time of admission. The clinical characteristics, etiologies, and prognosis
of different groups of patients were compared. Kaplan-Meier survival and Cox
regression analyses were used to determine the relationship between the FPG
level and 90-day all-cause mortality rate in patients with viral pneumonia.

Results Patients in the moderately- and highly-elevated FPG groups had a
higher proportion of severe disease and mortality compared with the normal FPG
group (P<0.001). Kaplan-Meier survival analysis showed a significant
trend toward higher mortality and increased cumulative risk at 30, 60, and 90 d
in patients with an FPG=7.0–14.0 mmol/L and an
FPG≥14 mmol/L (χ2=51. 77,
P<0.001). Multivariate Cox regression analysis revealed that compared
with an FPG<7.0 mmol/L, FPG=7.0 and
14.0 mmol/L (HR: 9.236, 95% CI: 1.106–77.119,
P=0.040) and FPG≥14.0 mmol/L (HR: 25.935,
95% CI: 2.586–246.213, P=0.005) were independent risk
factors for predicting the 90-day mortality rate in viral pneumonia
patients.

Conclusions The higher the FPG level at admission in a patient with viral
pneumonia, the higher the risk of all-cause mortality within 90 d.
Appropriate Surgical Margins for Excision of Squamous Cell Carcinoma of the Lower Lip
Authors: Hong Jung Hyun , Jung Chan Woo , Kim Hoon Soo , Bae Yong Chan
Published: May 2023

Background Squamous cell carcinoma (SCC) is the most common malignancy on the lower lip. Surgical excision, the standard treatment for SCC, requires full-thickness excision. However, no consensus exists about the appropriate surgical margin. Therefore, we investigated the appropriate surgical margin and excision technique by analyzing 23 years of surgical experience with lower-lip SCC.

Methods We reviewed 44 patients with lower-lip SCC who underwent surgery from November 1997 to October 2020. Frozen biopsy was performed with an appropriate margin on the left and right sides of the lesion, and the margin below the lesion was the skin above the sulcus boundary. If the frozen biopsy result was positive, an additional session was performed to secure a negative margin. Full-thickness excision was performed until the final negative margin. In each patient, the total number of sessions performed, final surgical margin, and recurrence were analyzed.

Results Forty-one cases ended in the first session, 2 ended in the second session, and 1 ended in the third session. The final surgical margins (left and right; n = 88) were 5 mm (66%), 7 mm (9%), 8 mm (2.3%), 10 mm (20.4%), and 15 mm (2.3%). During an average follow-up of 67.4 months (range, 12–227 months), recurrence occurred in one patient.

Conclusion The final surgical margin was 5 mm in 66% (58/88) of the cases, and 97.7% (86/88) were within 10 mm. Therefore, we set the first frozen biopsy margin to 5 mm, and we suggest that a 5-mm additional excision is appropriate when frozen biopsy results are positive.
Relationship between Psychological States and Coping in Reproductive Cancer Patients in the Context of the Pandemic
Authors: Menon Bindu , Gadiraju Padmaja
Published: May 2023

Introduction Cancer is known as a disease caused by an uncontrolled division of abnormal cells with the potential to proliferate and destroy body tissues. While it is not uncommon to observe changes in psychological states among patients with cancer, the pandemic situation has been reported to have an impact more severely.

Objective This study attempts to understand the psychological problems of cancer patients, and the process of coping adopted by reproductive cancer patients during the period of the pandemic.

Materials and Methods This study uses a correlation research design and the tools used for assessment were the four-dimensional symptom questionnaire and Brief COPE inventory. Through nonrandom sampling, a sample of 120 cancer patients diagnosed with reproductive cancer, both male and female from the regional cancer center and private cancer hospitals in Hyderabad, was recruited for the pandemic period from May 2020 to September 2021. Descriptive statistics, correlation, and regression statistical analysis methods were implemented.

Results Significant negative correlation was observed between psychological states and coping. Using multiple linear regression analysis, it was found that distress and depression predict problem-solving coping, distress and anxiety predict emotion-solving coping, and distress predicts adaptive coping.

Conclusion This study examines the psychological factors and coping methods in adapting to the dual challenges of illness and potential risk of infection transmission, and emphasizes designing an effective intervention. During the coronavirus disease 2019 crisis, the lack of support through psychological counseling to address their coping mechanisms to face the challenges is also glaring.

Until the coronavirus disease 2019 (COVID-19) pandemic, much of the scientific community and the general public lacked an appreciation of the impact of decreased smell function on everyday life, including the importance of this sensory system for safety, nutrition, and overall quality of life. It is now well established that the SARS-CoV-2 virus inflicts measurable but frequently reversible smell loss during its acute phase. Indeed, in many studies such loss is the most common symptom of COVID-19. Permanent or long-term deficits (i.e., deficits lasting over a year) may occur in up to 30% of those who have been infected, including the development of odor distortions (dysosmias; parosmias). This review presents up-to-date information on the epidemiology, severity, and pathophysiology of COVID-19-related smell dysfunction, including its association with psychological and neurological sequelae.

Purpose The aim of this study was to evaluate regional disparities in access to EyeSi surgical simulation training among U.S. ophthalmology residency programs.

Methods Access to EyeSi simulation was determined from sales data (2021) provided by VRMagic. Key demographic metrics of the primary counties of U.S. residency training programs were retrieved from the U.S. Census Bureau Database (2019) and PolicyMap (2021). Demographic metrics, Veterans Affairs (VA) hospital affiliation, and Doximity residency program ranking (2021) were compared using the Mann–Whitney U test and Fisher's exact test.

Results A total of 124 residency training programs across 95 U.S. counties were included. Regional density (number of EyeSi simulators/million people) was calculated; the west had a significantly lower density when compared with the northeast (NE), south, and midwest (0.4 vs 1.0, 1.3, 1.1, respectively). In the NE, there was a significantly lower population of Blacks (p = 0.01), Hispanics (p = 0.028), and Native Americans (p = 0.008) residing in counties with access to EyeSi, compared with counties without EyeSi access. Programs with EyeSi access (N = 95) had a median Doximity ranking of 52.5, whereas programs without EyeSi access (N = 35) had a lower median ranking of 94 (p < 0.001).

Conclusion Our analysis demonstrates significant disparities in access to EyeSi simulation training in the United States that could disproportionately impact minority communities. Access to an EyeSi simulator was associated with higher residency ranking independent of VA affiliation.

The sheet samples of thermally exfoliated graphite (TEG)–carbon nanotubes (CNT) composites (TEG-CNT-cs) were obtained by persulphate oxidation using chemical (CO) and electrochemical (anode) oxidation (ECAO). Electron microscopy reveals multi-layered structures of few-layer graphene nanosheets with folded and tubular-like fragments. The effective thermal diffusivity values were estimated by nonstationary photo-pyroelectric thermophysical characterization using the heat pulse and thermowave modulation methods. Comparison with other carbon (C-) based thermal management materials shows that TEG-CNT-cs exhibit thermal diffusivity, effusivity, and conductivity comparable with those of actual C–polymer- and C–C-composites. For TEG-CNT-cs, evaluated values of phonon mean free path (MFP) and relaxation time (RT) are in the ranges estimated for defective graphene. The values of diffusivity and effusivity, MFP, and RT are lower for denser TEG-CNT-cs obtained by ECAO and are higher for less dense TEG-CNT-cs obtained by CO. The obtained diffusivity and effusivity values designate TEG-CNT-cs as suitable thermal management materials.

Exact formulation for hysteresis loops and energy loss in Stoner–Wohlfarth systems
Authors: Appino C.
Published: May 2023

We propose an exact expression to describe the hysteresis loops of an ensemble of Stoner–Wohlfarth particles undergoing an alternating quasi-static magnetic field. A statistical approach, which treats the quantities characterizing each particle as random variables, is adopted to get the orientation distribution of the local polarizations with respect to the applied field direction and the constitutive equation of the whole particle assembly. The hysteresis loop area gives the energy loss figure, but we have also obtained a straightforward integral expression for this quantity. The analytical relationships for the symmetric loops and the losses are successfully tested against numerical results, and the mathematical method adopted also displayed the ability to reproduce the “elemental loop” associated with any given particle of the system. While having a fundamental character, the proposed approach bears applicative interest, representing a versatile tool as the core of codes that simulate the behavior of devices employing magnetic components.

We investigated the spin–orbit torque (SOT) and unidirectional spin Hall magnetoresistance (USMR) in Pt/CoFe/Ta trilayer as well as Pt/CoFe and CoFe/Ta bilayers with in-plane magnetic anisotropy by performing transverse and longitudinal second harmonic resistance measurements. Compared to the two bilayers, we found that the trilayer exhibits enhanced SOT and USMR due to the opposite spin Hall angles of Pt and Ta, which work together to enhance the spin accumulation in the trilayer. Furthermore, we found that thermal annealing has a significant influence on the magnitude and sign of the SOT and USMR in the Pt/CoFe/Ta trilayers. Specifically, we observed that both the damping-like SOT and USMR of the trilayer decrease as the annealing temperature increases, and they even change signs at an annealing temperature between 235 and 265 °C. In contrast, the sign change of the SOT and USMR upon annealing is absent in the Pt/CoFe and CoFe/Ta bilayers. These findings suggest that the sign of the SOT and USMR in the Pt/CoFe/Ta trilayer can be easily manipulated by using an appropriate thermal annealing treatment, which has important implications for the development of novel spintronic devices.

Reactive materials (RMs) are special type of impact-initiated energetic materials that have been widely studied with broad military application prospects. However, simulating the ignition and reaction of RMs using current numerical methods is difficult due to their complex mechanism related to high dynamic loads. In this work, based on a theoretical model consisting of impact ignition criteria and chemical reaction rate of polymer-based RMs, a numerical method with a unified equation of state was proposed and compiled as an executable program. Experiments consisting of typical polytetrafluoroethylene /Al RM projectiles impacting double-spaced plates were conducted and simulated using the user-compiled program, and the results verified the effectiveness of the numerical method. The simulation also qualitatively analyzed the second-collision induced reaction enhancement mechanism. In addition, the results revealed that the kinetic-chemical combined effect is a crucial factor that determined the damage enhancement effect on the rear plates.
Vortex zone dynamics in premixed flame under complex gravity and acoustic impact

Published: May 2023

An inverted conical, plane-symmetrical premixed methane–air flame stabilized by a bluff body under acoustic excitation and various gravity conditions was experimentally investigated. Recirculation zone characteristics were found by means of the phase-resolved particle image velocimetry method. An increase in the size of the longitudinal vortex zone was shown with an increase in both fuel concentration and flow velocity under normal and reverse gravity. The longitudinal size of the vortex zone is independent of frequency, regardless of the direction of gravity at low flow velocity (≤5 m/s) in a stoichiometric flame under the considered excitation frequency range (40–420 Hz). With a flow velocity increase, the size of the vortex zone becomes sensitive to the excitation frequency. An increase in the excitation frequency results in a length decrease in the vortex zone. In rich flames, an inverse relation of the longitudinal vortex zone size to the excitation frequency is observed at lower velocities (5 m/s) for normal gravity conditions. Whereas, under conditions of inverted gravity, the fuel air ratio increase does not lead to such a relation; the vortex zone has a constant length under various excitation frequencies. An external acoustic excitation causes a periodic change in the vortex zone longitudinal size, and for a stoichiometric mixture, the amplitude does not depend on the disturbance frequency. For a rich mixture, a frequency increase results in an amplitude decrease. For selected frequencies and flow velocities, desynchronization of the vortex zone oscillations with external disturbances is observed.

The frame rate of conventional high-speed imaging devices is limited by exposure time and signal read-out time. Structured imaging is able to push the frame rate beyond the limit of the imaging device. This work demonstrates the feasibility of potential TeraHz rate structured imaging with a multiplexed structured imaging setup. In this work, a multiplexed structured image capture system was employed to image UV laser induced krypton-II emission lines at 10 GHz. The measured emission intensity of the 764 nm line over time suggests a temporal resolution of 97 ps. The temporal resolution is adjustable, and the frame rate can be further increased to the TeraHz level.
