Authors: Guénot Jade , Trotter Yves , Delaval Angélique , Baurès Robin , Soler Vincent , Cottereau Benoit R.
Published: September 2023

Aging impacts human observer’s performance in a wide range of visual tasks and notably in motion discrimination. Despite numerous studies, we still poorly understand how optic flow processing is impacted in healthy older adults. Here, we estimated motion coherence thresholds in two groups of younger (age: 18–30, n = 42) and older (70–90, n = 42) adult participants for the three components of optic flow (translational, radial and rotational patterns). Stimuli were dynamic random-dot kinematograms (RDKs) projected on a large screen. Participants had to report their perceived direction of motion (leftward versus rightward for translational, inward versus outward for radial and clockwise versus anti-clockwise for rotational patterns). Stimuli had an average speed of 7°/s (additional recordings were performed at 14°/s) and were either presented full-field or in peripheral vision. Statistical analyses showed that thresholds in older adults were similar to those measured in younger participants for translational patterns, thresholds for radial patterns were significantly increased in our slowest condition and thresholds for rotational patterns were significantly decreased. Altogether, these findings support the idea that aging does not lead to a general decline in visual perception but rather has specific effects on the processing of each optic flow component.

Authors: Jiang Hu , Pu Hengping , Huang Nanqu
Published: September 2023

The aim of this study was to analyze the current situation and risk factors of multi-drug-resistant organism (MDRO) infection in Neuro-intensive care unit (ICU) patients, and to develop the risk predict model. The data was collected from the patients discharged from Neuro-ICU of grade-A tertiary hospital at Guizhou province from January 2018 to April 2020. Binary Logistics regression was used to analyze the data. The model was examined by receiver operating characteristic curve (ROC). The grouped data was used to verify the sensitivity and specificity of the model. A total of 297 patients were included, 131 patients infected with MDRO. The infection rate was 44.11%. The results of binary Logistics regression showed that tracheal intubation, artery blood pressure monitoring, fever, antibiotics, pneumonia were independent risk factors for MDRO infection in Neuro-ICU (P < 0.05), AUC = 0.887. The sensitivity and specificity of ROC curve was 86.3% and 76.9%. The risk prediction model had a good predictive effect on the risk of MDRO infection in Neuro ICU, which can evaluate the risk and provide reference for preventive treatment and nursing intervention.

Renal tubule has distinct metabolic features and functional activity that may be altered during kidney disease. In this paper, we present label-free functional activity imaging of renal tubule in normal and obstructed mouse kidney models using three-dimensional (3D) dynamic optical coherence tomography (OCT) ex vivo. To create an obstructed kidney model, we ligated the ureter of the left kidney for either 7 or 14 days. Two different dynamic OCT (DOCT) methods were implemented to access the slow and fast activity of the renal tubules: a logarithmic intensity variance (LIV) method and a complex-correlation-based method. Three-dimensional DOCT data were acquired with a 1.3 $$\upmu$$
μ
m swept-source OCT system and repeating raster scan protocols. In the normal kidney, the renal tubule appeared as a convoluted pipe-like structure in the DOCT projection image. Such pipe-like structures were not observed in the kidneys subjected to obstruction of the ureter for several days. Instead of any anatomical structures, a superficial high dynamics appearance was observed in the perirenal cortex region of the obstructed kidneys. These findings suggest that volumetric LIV can be used as a tool to investigate kidney function during kidney diseases.
A deep phenotyping approach to assess the association of handedness, early life factors and mental health

Published: September 2023

The development of handedness and other form of functional asymmetries is not yet understood in its critical determinants. Early life factors (e.g., birth weight, birth order) have been discussed to contribute to individual manifestations of functional asymmetries. However, large-scale data such as the UK Biobank suggest that the variance in handedness that is explained by early life factors is minimal. Additionally, atypical handedness has been linked to clinical outcomes such as neurodevelopmental and psychiatric disorders. Against the background of this triad, the current study investigated associations between different forms of functional asymmetries and (a) early life factors as well as (b) clinical outcomes. Functional asymmetries were determined by means of a deep phenotyping approach which notably extends previous work. In our final sample of N = 598 healthy participants, the different variables were tested for associations by means of linear regression models and group comparisons (i.e., ANOVAs and Chi-squared tests). Confirming previous findings from larger cohorts with shallow phenotyping, we found that birth factors do not explain a substantial amount of variance in functional asymmetries. Likewise, functional asymmetries did not seem to have comprehensive predictive power concerning clinical outcomes in our healthy participants. Future studies may further investigate postulated relations in healthy and clinical samples while acknowledging deep phenotyping of laterality.

Nearly a century after the first reports of Rift Valley fever (RVF) were documented in Kenya, questions on the transmission dynamics of the disease remain. Specifically, data on viral maintenance in the quiescent years between epidemics is limited. We implemented a cross-sectional study in northern Kenya to determine the seroprevalence, risk factors, and ecological predictors of RVF in humans and livestock during an interepidemic period. Six hundred seventy-six human and 1,864 livestock samples were screened for anti-RVF Immunoglobulin G (IgG). Out of the 1,864 livestock samples tested for IgG, a subset of 1,103 samples was randomly selected for additional testing to detect the presence of anti-RVFV Immunoglobulin M (IgM). The anti-RVF virus (RVFV) IgG seropositivity in livestock and humans was 21.7% and 28.4%, respectively. RVFV IgM was detected in 0.4% of the livestock samples. Participation in the slaughter of livestock and age were positively associated with RVFV exposure in humans, while age was a significant factor in livestock. We detected significant interaction between rainfall and elevation's influence on livestock seropositivity, while in humans, elevation was negatively associated with RVF virus exposure. The linear increase of human and livestock exposure with age suggests an endemic transmission cycle, further corroborated by the detection of IgM antibodies in livestock.
Paired ATAC- and RNA-seq offer insight into the impact of HIV on alveolar macrophages: a pilot study
Authors: Staitieh Bashar S. , Hu Xin , Yeligar Samantha M. , Auld Sara C.
Published: September 2023

People with HIV remain at greater risk for both infectious and non-infectious pulmonary diseases even after antiretroviral therapy initiation and CD4 cell count recovery. These clinical risks reflect persistent HIV-mediated defects in innate and adaptive immunity, including in the alveolar macrophage, a key innate immune effector in the lungs. In this proof-of-concept pilot study, we leveraged paired RNA-seq and ATAC-seq analyses of human alveolar macrophages obtained with research bronchoscopy from people with and without HIV to highlight the potential for recent methodologic advances to generate novel hypotheses about biological pathways that may contribute to impaired pulmonary immune function in people with HIV. In addition to 35 genes that were differentially expressed in macrophages from people with HIV, gene set enrichment analysis identified six gene sets that were differentially regulated. ATAC-seq analysis revealed 115 genes that were differentially accessible for people with HIV. Data-driven integration of the findings from these complementary, high-throughput techniques using xMWAS identified distinct clusters involving lipoprotein lipase and inflammatory pathways. By bringing together transcriptional and epigenetic data, this analytic approach points to several mechanisms, including previously unreported pathways, that warrant further exploration as potential mediators of the increased risk of pulmonary disease in people with HIV.

Published: September 2023

Nutrient pattern analysis is an easy way to compare nutrient intakes across different nations due to the universality of nutrients nature. The purpose of this study was to examine the relationship between dietary nutrient patterns (NPs) and circulating 25(OH)D concentrations with sleep duration and sleep quality among Iranian adults. We used a multistage cluster random sampling method to enroll 535 adults in this cross-sectional investigation. A validated food frequency questionnaire was applied to evaluate typical dietary intakes. Fasting blood samples were obtained to determine levels of circulating 25(OH)D. Sleep characteristics were assessed using the Pittsburgh Sleep Quality Index (PSQI). Participants had a mean age of 42.57 years and 51.2% of them had insufficient or deficient levels of serum vitamin D. Three NPs were identified: "high animal protein", "high vegetable" and "high carbohydrate". After adjustments for potential confounders, no significant associations were observed between "high animal protein" pattern and short sleeping or sleep quality. Greater adherence to "high vegetable" NP was associated with lower odds of short sleeping (OR 0.24; 95% CI 0.10, 0.54) and poor sleep quality (OR 0.45; 95% CI 0.20, 1.05). Stratified analysis revealed that these associations were stronger in normal-weight participants. Greater adherence to "high carbohydrate" NP, on the other hand, was connected to higher odds of short sleeping (OR 2.83; 95% CI 1.20, 6.72). Low adherence to "high vegetable" pattern and vitamin D insufficiency/deficiency were jointly associated with increased odds of short sleeping (OR 3.42, 95% CI 1.42, 6.64). High adherence to pattern comprising mainly of vegetable nutrients was associated with a reduced likelihood of being short sleepers and having poor sleep quality in Iranian adults, especially among those with a normal weight. Lower adherence to vegetable NP and insufficient/deficient vitamin D levels were synergistically associated with greater likelihood of being short sleepers. Greater adherence to carbohydrate NP was associated with an increased likelihood of short sleeping.

Published: September 2023

Breast cancer is the most prevalent and leading cause of mortality worldwide among women. Cell-free DNA (cfDNA) analysis is an alternative quantitative approach to conventional methods for cancer diagnosis. The current research project aimed to determine the efficacy of cfDNA as a diagnostic biomarker in breast cancer patients in Pakistan. Eighty-four female breast cancer patients were selected as cases, and 152 healthy females as controls. Immunohistochemistry was performed to identify tumor biomarkers along with clinical profiling. cfDNA was extracted from serum using the phenol–chloroform method. The cfDNA level in the serum was estimated using Agarose Gel Electrophoresis and Nanodrop. SPPS version 25.0 was used to perform statistical analyses. The results showed that the cancer biomarkers were significantly associated with breast cancer. The changes in hematological parameters were insignificant, whereas the biochemical parameter variations between the cases and controls were statistically significant. A significant association of cfDNA level with breast cancer was observed. Further cfDNA levels and cancer biomarkers were not statistically significant. A significant correlation was observed between cfDNA and biochemical parameters, except for creatinine, whereas hematological parameters showed no significant correlation.ROC analysis declared cfDNA as an authentic diagnostic marker for breast cancer. It was concluded that the level of cfDNA is significantly increased in breast cancer patients and can be utilized as a diagnostic biomarker.
Coherent multipolar amplification of chiroptical scattering and absorption from a magnetoelectric nanoparticle
Authors: Wu Hsin-Yu , Vollmer Frank
Published: September 2023

Background-free detection of inherently weak chiroptical signals remains one of the great challenges in research communities and industries. We demonstrate coherent multipolar amplification of chiroptical responses via a magnetoelectric nanoparticle capped with an optically active monolayer encapsulated in a lossless background medium. Such an achiral nanoparticle can simultaneously support both electric and magnetic Mie-type resonances. We show how the combined excitation of orthogonal multipolar modes of the same order boosts the magnetoelectric coupling induced by the adsorbed chiral molecules, thus enabling coherently enhanced chiroptical responses from the ligand-capped magnetoelectric nanoparticle and allowing for absolute chirality measurements, in comparison with non-magnetoelectric nanoparticles. Furthermore, we develop rigorous expressions to separate relative contributions of chiral and nonchiral portions of circular differential absorption cross section, and analyzed the chirality-dependent far-field radiation patterns at different overlapped multipolar modes, providing a theoretical framework to understand the underlying enhancement mechanism of the magnetoelectric-assisted sensing of molecular chirality.

Published: September 2023

Background

Living in a disadvantaged neighborhood is associated with worse health outcomes, including brain health, yet the underlying biological mechanisms are incompletely understood. We investigated the relationship between neighborhood disadvantage and cortical microstructure, assessed as the T1-weighted/T2-weighted ratio (T1w/T2w) on magnetic resonance imaging, and the potential mediating roles of body mass index (BMI) and stress, as well as the relationship between trans-fatty acid intake and cortical microstructure.

Methods

Participants comprised 92 adults (27 men; 65 women) who underwent neuroimaging and provided residential address information. Neighborhood disadvantage was assessed as the 2020 California State area deprivation index (ADI). The T1w/T2w ratio was calculated at four cortical ribbon levels (deep, lower-middle, upper-middle, and superficial). Perceived stress and BMI were assessed as potential mediating factors. Dietary data was collected in 81 participants.

Results

Here, we show that worse ADI is positively correlated with BMI (r = 0.27, p = .01) and perceived stress (r = 0.22, p = .04); decreased T1w/T2w ratio in middle/deep cortex in supramarginal, temporal, and primary motor regions (p < .001); and increased T1w/T2w ratio in superficial cortex in medial prefrontal and cingulate regions (p < .001). Increased BMI partially mediates the relationship between worse ADI and observed T1w/T2w ratio increases (p = .02). Further, trans-fatty acid intake (high in fried fast foods and obesogenic) is correlated with these T1w/T2w ratio increases (p = .03).

Conclusions

Obesogenic aspects of neighborhood disadvantage, including poor dietary quality, may disrupt information processing flexibility in regions involved in reward, emotion regulation, and cognition. These data further suggest ramifications of living in a disadvantaged neighborhood on brain health.

Published: September 2023

Background:

Data on seroconversion rates after SARS-CoV-2 infection in young children (<6 years) is scarce. The present study compares seroconversion rates between young children and adults and identifies associated factors.

Methods:

The COALA study (“Corona-outbreak-related examinations in daycare centers”) investigated transmission dynamics of SARS-CoV-2 in daycare centers and associated households (10/2020-06/2021). 114 individuals tested positive for SARS-CoV-2 through PCR either prior to the study period by health authorities or in PCR testing during the study period. Two capillary blood samples were obtained within five weeks consecutively and tested for SARS-CoV-2 IgG-antibodies (second sampling depending on positive PCR). Results from 91 participants (38 young children 1–6 years, 53 adults) were included in the analyses.

Results:

Seroconversion rate in young children is significantly higher than in adults (97.4% versus 66%). High viral load and longer time interval between the probable date of infection and antibody testing are associated with seroconversion.

Conclusions:

Our findings depict substantial development of specific antibodies in young children after SARS-CoV-2 infection. This may provide temporary protection from re-infection for young children or severe disease for this age group.

A Measure of Swallow Effort Using the Borg Category Ratio 10 Perceived Exertion Scale
Authors: Cortez-Aoyagi Mari , Gufstason Erin , Murphy Amanda , van Mersbergen Miriam
Published: September 2023

Purpose:

With the emphasis on patient-centered care, tools to adequately measure the experience of swallowing are an important part of clinical care. Swallowing effort is one such experience. However, few measurement tools capture swallowing effort in the moment of swallowing to quantify effort. The Borg Category Ratio 10 Perceived Exertion Scale (Borg CR 10), designed to track effort in a variety of tasks from lifting, breathing, and running, appears to be a likely candidate to measure swallowing effort in the moment of swallowing.

Method:

In a quasi-random design, 32 healthy individuals, ages 40–80 years (average age: 63 years), consumed seven bolus consistencies in both small and large quantities, three times. Following each individual swallow, they rated the amount of effort it took to swallow each bolus using an adapted Borg CR 10 for swallowing effort.

Results:

Results showed significantly greater reports of swallowing effort on the Borg CR 10 for more adhesive consistencies, larger quantities, and increased number of swallows.

Conclusion:

Results suggest that the Borg CR 10 is a reasonable measurement tool to capture patient-perceived effort in swallowing.
Recognition of foreign-accented vocoded speech by native English listeners
Authors: Yang Jing , Barrett Jenna , Yin Zhigang , Xu Li
Published: September 2023

This study examined how talker accentedness affects the recognition of noise-vocoded speech by native English listeners and how contextual information interplays with talker accentedness during this process. The listeners included 20 native English-speaking, normal-hearing adults aged between 19 and 23 years old. The stimuli were English Hearing in Noise Test (HINT) and Revised Speech Perception in Noise (R-SPIN) sentences produced by four native Mandarin talkers (two males and two females) who learned English as a second language. Two talkers (one in each sex) had a mild foreign accent and the other two had a moderate foreign accent. A six-channel noise vocoder was used to process the stimulus sentences. The vocoder-processed and unprocessed sentences were presented to the listeners. The results revealed that talkers’ foreign accents introduced additional detrimental effects besides spectral degradation and that the negative effect was exacerbated as the foreign accent became stronger. While the contextual information provided a beneficial role in recognizing mildly accented vocoded speech, the magnitude of contextual benefit decreased as the talkers’ accentedness increased. These findings revealed the joint influence of talker variability and sentence context on the perception of degraded speech.

Utilization of Calathea Lutea Stem as Part Material
Authors: Lim Christina , Gandawijaya R. Asep Ahadiat
Published: September 2023

Calathea Lutea is a plant that is often found in Indonesia. Calathea Lutea is usually only used as an exterior plant because it has a wide leaf shape and a strong stem structure. If further investigated, the strength of the stem structure of the Calathea plant has the potential to be used as a material for interior parts. The research aims to find the best method for utilizing Calathea Lutea stems, especially when used as sheets for interior elements. Calathea Lutea stems are processed through various methods to find the most suitable method. Before the experiment, the stems of Calathea Lutea will be dried, and the methods will be carried out in three ways: laminating, weaving, and spinning. The results of the processing of Calathea Lutea stems will be subjected to several tests, such as strength, resilience, and flexibility. The stem of Calathea Lutea that has potential as an interior part is the one that uses the least amount of adhesive and has passed the tests carried out. It is hoped that the processing of Calathea Lutea stems can be used as a substitute material as a structural or visual element to replace other materials that are often found in Indonesia.

Authors: Suzianti Amalia , Wibowo Andy Prasetio , Fibra Adsina
Published: September 2023

Economy growth is very dynamic, and companies use organizational transformation strategies for their resilience and sustainability in the era of globalization. The implementations of organizational transformation provide several internal changes. However, several published research showed a low success rate of less than 50% of the organizational transformation strategy. These failures are due to mismanagement actions in handling employee behavioral changes as the impact of the transformation strategy. This paper focused on behavioral changes in one of the mining companies in Indonesia during the recent organizational transformation. This research aimed to discuss and provide feedback to the company’s management. Therefore, the company can perform the best decision-making in achieving transformation strategy goals. A research model was developed based on the Theory of Planned Behaviour and validated in PLS-SEM (Partial Least Square – Structural Equation Model) to investigate change management implementation and define significant factors influencing employees’ positive behavior. The research found that employees’ intention factors significantly influenced the positive behavior of employees. Moreover, their attitudes and perceived control significantly influenced the employees’ intentions. However, the subjective norms did not significantly influence the employee’s intention. The Importance-Urgency Mapping was also applied to define the prioritization of management factors within the company.

Published: September 2023

The growth of ready-to-drink (RTD) jasmine black tea in Indonesia is increasing due to its unique flavor and convenience. This research aimed to investigate the preferences of college students, representing Gen Z as the second largest demographic proportion, across commercial RTD jasmine black teas (coded as SSX, PHZ, GLA, and KTO) using 3-point JAR (Just-About-Right) scales. As many as 101 consumers participated in assessing five sensory attributes (jasmine aroma, sweetness, bitterness, tea flavor, and astringency) and overall liking. The most penalized attributes impacting product performance were identified using penalty analysis. In contrast, the association between the JAR level of sensory attributes and overall liking across samples was explored using PCA (Principal Component Analysis). The overall penalty showed that tea aroma and astringency influenced the overall liking for all samples. Jasmine aroma and bitterness showed no effect on KTO liking, while only GLA liking was unaffected by sweetness. PCA biplot explained that the GLA sample had the strongest correlation with overall liking as represented by JAR level of tea flavor, astringency, jasmine aroma, and sweetness but was slightly influenced by JAR level of bitterness. It could be concluded that GLA was a sample with the optimum preferences perceived by college students.

Published: September 2023

D-tagatose is known as a type of sugar that has low-calorie and numerous benefits. The sugar is also known to have potential for the food industry. D-tagatose can be produced biologically using the L- arabinose isomerase (L-AI) enzyme. However, sustainable production of D-Tagatose still faces an issue due to the specificity of the enzyme and the requirement of a high temperature for large-scale production. This study aims to develop an approach to discovering new bacteria that have the L-AI enzyme by implementing the DNA marker technique. We collected protein sequences from a public biological database and performed a multiple-sequence alignment. Then, the degenerate primers were designed based on the aligned sequence. The primer characterization was carried out using Oligo Calc. In-silico PCR amplification was also performed to test the primers’ specificity. Overall, the primers’ properties have met the criteria for optimally working primers. In addition, gel electrophoresis confirmed the successful amplification of the L- AI enzyme from several bacteria. Our study could be used to discover the L-AI enzyme that has the desired characteristics, which allows the sustainable production of D-tagatose.

Published: September 2023

— Café is a retail F&B place for eating and drinking fast food and presenting a relaxed or informal atmosphere. Café, which is a public space where customers spend time, of course, must maintain ventilation in the café to ensure the customer’s thermal comfort. For this reason, paying attention to air circulation in the cafe is essential. The author takes the ice cream cafe in Malang as the case study object in this case study research. This research focuses on ventilation on the first floor of the café. After making observations, it was found that the air circulation in the cafe is not smooth and limited because of the closed space. Despite having two air conditioners running, the restaurant’s atmosphere started to feel limiting as the survey was being conducted. The lack of ventilation in this enclosed room further reduces the café’s thermal comfort. To solve this problem, the author provides a solution for implementing cross-circulation by adding windows to the front and back of the café to maximize air circulation and using an exhaust fan in the café kitchen to maintain air quality. So with this, it can guarantee the thermal comfort of customers at this cafe.

The paper aims to criticize Indonesia and South Korea’s policy to relocate their national capital to achieve SDGs point 11 regarding sustainable cities and communities. In this paper, policies in Indonesia and South Korea will be analyzed to realize the SDGs by establishing particular institutions and incorporating the goals of the SDGs into national laws. Furthermore, an analysis of the public rejection of the National Capital Law in the two countries that have been submitted for judicial review in the Constitutional Court will be carried out. The research method used in this study is normative research with a statutory approach, case studies, and comparative laws. This research, a comparative study, focuses on the judiciary system in Indonesia and South Korea, which has similarities in the jurisdiction of the Constitutional Court. The result of this study is that Indonesia and South Korea, in achieving SDGs point 11, only show an increase in one indicator. The dynamics of relocating the national capital through the decision of the Constitutional Court will affect the achievement of SDGs in both countries. In the future, every policy in law-making must involve the broader community as a manifestation of a democratic state.
Dissonance in generative AI use among student writers: How should curriculum managers respond?
Authors: Talaue Franklin G.
Published: September 2023

This qualitative study investigated the case of ChatGPT use by five students in an English for Academic Purposes (EAP) class comprised of 28 students in total. The results of the analysis revealed dissonance in the way the subjects of the study had intended to use ChatGPT in their written assessments and how they used it, six weeks into the writing program. The results of the study revealed that their intention to use ChatGPT may have been within the remit of fair use, but their written output as evaluated by an AI detection tool revealed that the students might have violated academic integrity. This study has clear implications for the role of educators to guide students on how to use AI in their written assessments in such a way that they uphold academic integrity. Educational institutions, therefore, should take a pedagogical stance on AI text generators, which means that proactive measures should be taken to embrace AI as an assistive tool for writing, but fair and guided use of the technology must be in place.

Currently, global uncertainty requires an effort to change to maintain the sustainability of the business. The demand for this change is also experienced by companies in the logistics field, one of them at PT Gateway Container Line. There were complaints from customers related to some shipments that suffered damage, then the decrease in the profit margin gained by PT Gateway Container Line, from 9.77% in 2021, to 9.69% by 2022, was an indication of the ongoing problems. To solve the problem, PT Gateway Container Line needs to make an effort to identify the factors that influence the performance of employees resulting in the company’s performance, i.e. self-efficiency factors, flexibility-ambidexterity, and subjective norms within the employee. Of the results of data using SmartPLS 4, obtained results such as self-effectiveness factors have a p-value of 0,000, whereas flexibilities-ambidexterity have p- values of 0.001 indicating that self-effectiveness and flexible-ambidexterity have a positive impact on company performance. As for the subjective norm, it gives a negative influence with a p-value of 0.385 This result provides guidance for PT Gateway Container Line for improvements in the side of self-efficiency and flexibility-ambidexterity of employees in order to improve employee performance.

Football, a beloved game that is enjoyed by people of all races, ethnicities, genders, and orientations, is unfortunately marred by racism and discrimination. To combat this, the Eastern European Development Program was launched during EURO 2012 to build infrastructure in the two host countries. This paper examines the implementation of the transnational advocacy network in conducting the Eastern European Development Program, and how the FARE Network used it to build capacity, launch projects, and host celebratory ceremonies. Through literature studies focusing on racism, discrimination, and the Eastern European Development Program, a framework was created to illustrate the success of the FARE Network in implementing the transnational advocacy network. The research shows that the FARE Network was successful in involving important stakeholders and global audiences, and ultimately achieved its goal of creating a more equitable and inclus, transnational advocacy.

The Creativity in the Design of Hospital Inpatient Rooms with Biophilic Criteria
Authors: Simarmata Andriano
Published: September 2023

The inpatient room in hospital facilities has rules and standards but should be optimized with a creative spatial design approach, such as biophilic principles. The principles of biophilic consist of 14 patterns and are categorized into three criteria: nature in the space, natural analogues, and nature of the space with interior design consideration. The biophilic design approach is flexible, while the hospital facilities have standards that could limit the design exploration. This study aims to see the potential of biophilic principles in hospital design by young designers. This research was conducted by a design project and involved lecturers and design experts from the industry related. The method used was teaching in class and encouraging the creativity and activeness of participants by conducting studies individually and in groups. The main topics in class were enriched with biophilic material and design standards for hospital inpatient rooms set by the Ministry of Health of the Republic of Indonesia. Various results were found; there are 15 inpatient room designs, all with biophilic criteria based on students’ creativity. The design project successfully enhanced the creativity of biophilic criteria implemented in the inpatient room, although there are various constraints in hospital design standards.
Texts to Movies: Does Adaptation Limit or Liberate Meaning?
Authors: Witomo Endrico , Rifai Irfan
Published: September 2023

There is a debate over the measure of a successful literary work adaptation. One party argues that a successful adaptation follows the originality of the story so the viewers will not label the adaptation as “unfaithful” to the original work. However, the other party suggests that an adaptation should not follow the original story and that it should become a new version of the original work. These debates indirectly discuss whether an adaptation should limit the interpretation of the original story when adapting or giving freedom when interpreting the meaning of the original work to the adapted work. Following the debate, this research aims to explore the process of a short story adaptation to a short movie to reveal the changes of meaning as portrayed by the text and the movie by using semiotics theory. Observation and interview were used to gather data from the producers of both text and short film during the production of the short film to understand the author’s and the adapters’ interpretation of the story. The result of this research shows that turning the colours mentioned in the written work into visual was one of the major changes that took place in the short film production and in the written work. This research concludes that an adaptation liberates the meaning of a story by turning a single mode story into a multimodal story that represents rich interpretations and visual representations.
