Authors: Song Young A , Kim Minkyeong
Published: September 2023

Purpose: This study analyzed the effects of virtual reality simulation-based problem-based learning on nursing students’ critical thinking ability, problem-solving ability, and self-efficacy in the nursing care of women undergoing induction of labor.Methods: A nonequivalent control group pretest and posttest design was employed. The study participants included 52 nursing students (24 in the experimental group and 28 in the control group). The experimental group took a problem-based learning (PBL) class in the first week, and then engaged in self-directed learning using virtual reality simulation. In the second week, lectures about emergency nursing care for induction of labor and drug administration were given. The control group participated in PBL in the first week and lectures in the second week. The study was conducted from April 17 to May 19, 2023. Data were analyzed using the chi-square test, Fisher exact test, analysis of variance, and the independent t-test.Results: Before-and-after differences between the two groups were statistically significant in problem solving ability (t=–5.47, p<.001) and self-efficacy (t=–5.87, p<.001). Critical thinking ability did not show a statistically significant difference between the two groups. The score for satisfaction with the virtual reality simulation program was 3.64±5.88 out of 5 in the experimental group.Conclusion: PBL education using a virtual reality simulation was found to be an effective way of teaching. Although convenience sampling was used, PBL education using virtual reality can be used as an educational strategy to enhance nursing students’ problem-solving ability and self-efficacy.

Authors: Kim Hyeonsik , Yoon Hyun-Kyu , Lee Hyeonhoon , Jung Chul-Woo , Lee Hyung-Chul
Published: September 2023

Background: Use of endotracheal tubes (ETTs) with appropriate size and depth can help minimize intubation-related complications in pediatric patients. Existing age-based formulae for selecting the optimal ETT size present several inaccuracies. We developed a machine learning model that predicts the optimal size and depth of ETTs in pediatric patients using demographic data, enabling clinical applications. Methods: Data from 37,057 patients younger than 12 years who underwent general anesthesia with endotracheal intubation were retrospectively analyzed. Gradient boosted regression tree (GBRT) model was developed and compared with traditional age-based formulae. Results: The GBRT model demonstrated the highest macro-averaged F1 scores of 0.502 (95% CI 0.486, 0.568) and 0.669 (95% CI 0.640, 0.694) for predicting the uncuffed and cuffed ETT size (internal diameter [ID]), outperforming the age-based formulae that yielded 0.163 (95% CI 0.140, 0.196, P < 0.001) and 0.392 (95% CI 0.378, 0.406, P < 0.001), respectively. In predicting the ETT depth (distance from tip to lip corner), the GBRT model showed the lowest mean absolute error (MAE) of 0.71 cm (95% CI 0.69, 0.72) and 0.72 cm (95% CI 0.70, 0.74) compared to the age-based formulae that showed an error of 1.18 cm (95% CI 1.16, 1.20, P < 0.001) and 1.34 cm (95% CI 1.31, 1.38, P < 0.001) for uncuffed and cuffed ETT, respectively.Conclusions: The GBRT model using only demographic data accurately predicted the ETT size and depth. If these results are validated, the model may be practical for predicting optimal ETT size and depth for pediatric patients.
Stroke prevention and intracranial hemorrhage risk in atrial fibrillation management: A mini review
Authors: Roychoudhury Rohon , Ma Shuangtao , Qian Chunqi
Published: September 2023

This mini-review examines the management of atrial fibrillation (AF) in patients at high risk of bleeding, with a focus on stroke prevention and intracranial hemorrhage risk. Anticoagulant therapy is commonly advised for AF patients, but it can elevate the risk of intracranial hemorrhage in certain individuals prone to bleeding. Two primary perspectives for managing high-risk patients are discussed: adhering to strict anticoagulation therapy or opting for alternative treatments like left atrial appendage closure (LAAC) or aspirin. The benefits and drawbacks of each approach are evaluated, emphasizing the importance of a personalized management plan based on patient risk profiles, comorbidities, and preferences. Ongoing research, including artificial intelligence, advances in LAAC devices, and combination therapies, is explored to enhance stroke prevention and minimize bleeding risk in AF management. A multidisciplinary approach and continuous investigation are vital to achieving better patient outcomes and overall care in this context.

Published: September 2023

BACKGROUND:

Intracerebral hemorrhage (ICH) carries significant morbidity and mortality. Previous single-center retrospective analysis suggests that end-stage renal disease (ESRD) is a risk factor for severe ICH and worse outcomes. This investigation aims to examine the impact of ESRD on ICH severity, complications, and outcomes using a multicenter national database.

METHODS:

The International Classification of Disease, Ninth and Tenth Revision Clinical Modification codes were used to query the National Inpatient Sample for patients with ICH and ESRD between 2010 and 2019. Primary endpoints were the functional outcome, length of stay (LOS), and in-hospital mortality. Multivariate variable regression models and a propensity-score matched analysis were established to analyze patient outcomes associated with baseline patient characteristics.

RESULTS:

We identified 211,266 patients with ICH, and among them, 7,864 (3.77%) patients had a concurrent diagnosis of ESRD. Patients with ESRD were younger (60.85 vs. 67.64, P < 0.01) and demonstrated increased ICH severity (0.78 vs. 0.77, P < 0.01). ESRD patients experienced higher rates of sepsis (15.9% vs. 6.15%, P < 0.01), acute myocardial infarction (8.05% vs. 3.65%, P < 0.01), and cardiac arrest (5.94% vs. 2.4%, P < 0.01). In addition, ESRD predicted poor discharge disposition (odds ratio [OR]: 2.385, 95% confidence interval [CI]: 2.227–2.555, P < 0.01), longer hospital LOS (OR: 1.629, 95% CI: 1.553–1.709, P < 0.01), and in-hospital mortality (OR: 2.786, 95% CI: 2.647–2.932, P < 0.01).

CONCLUSIONS:

This study utilizes a multicenter database to analyze the effect of ESRD on ICH outcomes. ESRD is a significant predictor of poor functional outcomes, in-hospital mortality, and prolonged stay in the ICH population.

Published: September 2023

The retina is often used to evaluate the vascular health status of eyes and the whole body directly and noninvasively in vivo. Retinal vascular parameters included caliber, tortuosity and fractal dimension. These variables represent the density or geometric characteristics of the vascular network apart from reflecting structural changes in the retinal vessel system. Currently, these parameters are often used as indicators of retinal disease, cardiovascular and cerebrovascular disease. Advanced digital fundus photography apparatus and computer-assisted analysis techniques combined with artificial intelligence, make the quantitative calculation of these parameters easier, objective, and labor-saving.

Published: September 2023

The retina, as an external extension of the diencephalon, can be directly, noninvasively observed by ocular fundus photography. Therefore, it offers a convenient and feasible mode to study nervous system diseases. Caliber, tortuosity, and fractal dimension, as three commonly used retinal vascular parameters, are not only the reflection of structural changes in the retinal microcirculation but also capture the branching pattern or density changes of the retinal microvascular network. Therefore, it contributes to better reflecting the subclinical pathological changes (e.g., lacunar stroke and small cerebral vascular disease) and predicting the risk of incident stroke and recurrent stroke.

Published: September 2023

Background:

The association between depressive symptoms and adverse outcomes in patients with coronary artery disease (CAD) is well recognized. However, few studies address the patient's perception of his physical and mental condition after a myocardial infarction (MI). The present study was designed to explore the subjective aspects of the psychological conditions in post-MI patients.

Method and Results:

A subject population of 8 male patients (age 59±5), selected by saturation sampling, with an average of 6 months post-MI, were submitted to an individual semi-structured interview and afterwards participated in 12 psychodynamic group sessions.

Conclusion:

There was a predominant non-acceptance of MI due to emotional barriers and this attitude has the potential to influence negatively the adherence to a comprehensive cardiovascular treatment, including pharmacological intervention for depression
Utility of Ultrasound Elastography to Evaluate Poststroke Spasticity and Therapeutic Efficacy: A Narrative Review
Authors: Lin Meng-Ting , Yang Shu-Mei , Wu Hao-Wei , Chen Yen-Hua , Wu Chueh-Hung
Published: September 2023

Poststroke spasticity (PSS) is a common complication that affects function and daily self-care. Conservative PSS treatments include traditional rehabilitation, botulinum toxin injection, and extracorporeal shock wave therapy. Currently, the Modified Ashworth Scale and Modified Tardieu Scale are widely used tools to clinically evaluate spasticity, but the best tool for PSS assessment remained controversial. Ultrasound elastography (UE), including shear wave and strain image as the emerging method to evaluate soft tissue elasticity, became popular in clinical applications. Spastic biceps and gastrocnemius muscles were reported to be significantly stiffer compared to nonparetic muscles or healthy control using shear wave or strain elastography. More studies investigated the utility, reliability, and validity of UE in patients with PSS, but the contemporary consensus for the utility of UE in the measurement and therapeutic follow-up of PSS remained lacking. Therefore, this narrative review aimed to appraise the literature on the shear wave and strain elastography on PSS and summarize the roles of UE in assessing the therapeutic efficacy of different PSS interventions.
In vitro Fertilization: An Alert for the Association of Placenta Previa and Vasa Previa – Ultrasound and Magnetic Resonance Imaging Findings
Authors: Trevizo Juliana Pagotto , Araujo Júnior Edward , Elito Júnior Julio
Published: September 2023

A 33-year-old woman, gravida 2 para 0, with a history of two previous miscarriages, underwent an investigation for recurrent miscarriage. After genetic counseling, the couple were submitted to the karyotype, which resulted in 45, X/46, XX mosaicism (mosaic Turner syndrome) in the wife result, while the husband chromosomal resulted in 46, XY (normal). After evaluating the options, the couple opted for in vitro fertilization. During prenatal follow-up, placenta and vasa previa were identified, considerably increasing the maternal–fetal mortality rate in this case. However, despite being a delicate and challenging case, the early diagnose was possible due to transvaginal ultrasound using color Doppler. Due to good care in obstetric follow-up, involving a multidisciplinary team, a therapeutic program and a successful outcome were possible. The patient underwent a cesarean section at 35 weeks of pregnancy, without complications, with a newborn in good general condition, despite the prematurity.
A Case of Shear Wave Velocity Reflecting the Disease Activity in Glomerulonephritis
Authors: Ono Sayaka , Nishino Tomohiko , Takahashi Kazuhiro , Mimaki Masakazu
Published: September 2023

Ultrasound elastography can measure tissue elasticity using the shear wave velocity (SWV). Evaluating disease activity with elastography instead of renal biopsy may be less invasive. However, to the best of our knowledge, although there are studies comparing different glomerular diseases using SWV, there are no reports that have measured glomerulonephritis longitudinally from the acute phase of the disease. This study aimed to assess whether SWV reflects disease activity in glomerulonephritis, and we continued to observe children with post-streptococcal acute glomerulonephritis (PSAGN) from the acute phase to over a year later. In this case, a 6-year-old boy diagnosed with PSAGN had impaired renal function, and was admitted and tested. He was placed in a prone resting position and measurements were taken from the back. SWV was measured ≥50 times at each examination, and the mean was calculated when the net amount of effective SWV was ≥50%. The tests were performed once in the acute phase and thrice during the recovery phase for 13 months. SWV was found to be significantly lower in the recovery period than during the disease onset, and continued to stay lower at each test during the recovery period (P < 0.02). In conclusion, this indicated that SWV fluctuated similarly to the disease activity of glomerulonephritis; therefore, we suggest using SWV measurement to estimate the disease activity in glomerulonephritis in children. Although more clinical cases are needed, SWV measurement is a noninvasive and reproducible imaging modality to estimate the disease activity in glomerulonephritis.
Prenatal Sonographic Three-dimensional Virtual Organ Computer-assisted Analysis Thymic Volume Calculation May Predict Intrauterine Growth Restriction
Authors: Dogan Zeki , Guven Emine Seda Guvendag , Albayrak Mehmet , Guven Suleyman
Published: September 2023

Background:

Intrauterine growth restriction (IUGR) refers to fetuses that are small for their gestational age. There is no effective test to predict this disease. The aim of our study is whether fetal three-dimensional (3D) ultrasonography (USG)-assisted thymus volume (TV) measurement predicts IUGR cases.

Methods:

Fetal 3D USG thymus measurement between 15 and 24 weeks of gestation was performed in a total of 100 women of reproductive age. Fetal TV was measured using the virtual organ computer-assisted analysis system program. All cases were followed up in terms of pregnancy complications until delivery.

Results:

IUGR was developed in six cases in total. In cases with IUGR, mean fetal TV was found to be statistically significantly lower than in healthy cases without it. When the fetal TV was taken as 0.1645, the sensitivity was calculated as 89.5% and the specificity as 50% for predicting IUGR. The use of low fetal volume parameters is a significant and good indicator for predicting IUGR according to the binary logistic regression analysis result.

Conclusion:

According to the results of this study, 3D fetal TV measurement may be used in routine second-trimester sonographic anomaly screening to predict the development of fetal IUGR. In this way, fetal mortality and morbidity caused by IUGR may be reduced.
Hematological Scoring System and its Correlation with Blood Culture, C-reactive Protein, and Micro-erythrocyte Sedimentation Rate in Early Diagnosis of Neonatal Sepsis
Authors: Amir Nawal , Ahmad Murad , Akhtar Kafil , Hassan Mohammad Jaseem
Published: September 2023

BACKGROUND:

Neonatal sepsis is a major health problem in our country. The cause for most of the deaths is not a failure to treat the infection, instead, it is the failure to treat it on time. Sepsis is usually identified by a gold-standard blood culture test. However, there is a need for a simple and cost-effective diagnostic tool with quick results.

MATERIALS AND METHODS:

A total of 70 neonates with clinical suspicion of sepsis were included in our study. The hematological parameters such as total leukocyte count(TLC), absolute neutrophil count (ANC), platelet count, immature neutrophil count, immature to total neutrophil ratio (I:T), immature to mature neutrophil ratio (I:M), toxic granules, and cytoplasmic vacuolation in neutrophil were correlated with C-reactive protein (CRP), blood culture and micro-erythrocyte sedimentation rate (micro-ESR). The performance of these hematological parameters was evaluated with the help of hematological scoring system (HSS).

RESULTS:

Among the hematological parameters, TLC has high sensitivity (77.8%) and specificity (72.1%), ANC has the least sensitivity (44.4%) but the highest specificity (96.7%), platelet count has high sensitivity (88.9%) but low specificity (44.3%), I:T and I:M ratio have the highest sensitivity (88.9% both), specificity (71.1% and 88.5%, respectively) and negative predictive value (91.3% and 92.8% respectively). ANC and I:M ratios have the highest positive predictive value (89.3% and 82.5%, respectively) in predicting the early diagnosis of neonatal sepsis.

CONCLUSION:

HSS along with CRP and micro-ESR can be used as a screening tool in neonates with clinical suspicion of sepsis as they are simple to perform, and can be done even in rural parts of the country.

Authors: Kumarguru B. N. , Sreegiri Sindhu , Swathi D. , Ramaswamy A. S. , Arathi C. A.
Published: September 2023

BACKGROUND:

Coronavirus disease 2019 (COVID-19) globally known as COVID-19 is a heterogeneous disease caused by the severe acute respiratory syndrome coronavirus 2. COVID-19 patients having severe disease and are critically ill are more prone to have abnormal coagulation prolife. It may lead to thromboinflammation in severe conditions.

AIM:

The aim is to evaluate the utility of coagulation parameters and inflammatory biomarkers in COVID-19 patients in the study conducted for 6 months duration.

MATERIALS AND METHODS:

It was a retrospective observational study conducted from April 2021 to September 2021 in a rural tertiary care referral Institute. Available data of the baseline values of coagulation parameters (platelet count [PLC], prothrombin time [PT], international normalized ratio [INR], partial thromboplastin time [PTT] and D-dimer) and inflammatory markers (C-reactive protein [CRP], serum lactate dehydrogenase [LDH], and serum ferritin) were evaluated with respect to the clinical severity of the disease and also the survival status of COVID-19 patients.

RESULTS:

One hundred and fifty-five cases of COVID-19-positive patients were analyzed. PT, INR, PTT, D-dimer, CRP, LDH, and ferritin had higher mean in severe cases than the nonsevere cases. PLC had higher mean in the severe cases than the nonsevere cases. PT, INR, PTT, D-dimer, CRP, LDH and ferritin had higher mean in nonsurvivors than the survivors. PLC had lower mean in nonsurvivors than the survivors.

CONCLUSION:

Baseline values of PT, INR, PTT, D-dimer, LDH, and ferritin may be considered reliable indicators of severity of COVID-19 disease. Baseline values of D-dimer, LDH, and ferritin may be considered a reliable indicator of survival of patients suffering from COVID-19 infection.

Authors: Sharshera Homam M. , Maghraby Shereen M. El , Aglan Shaimaa A. , Mikhael Irene L. , Balbaa Ola A.
Published: September 2023

BACKGROUND:

Beta-thalassemia is an autosomal recessive hereditary blood disorder occurs due to absent or diminished β-globin chains synthesis. The transformation from fetal to adult in globin synthesis is controlled by different mechanisms; one of those is BCL11A which is downregulated by microRNA-210 (miRNA-210). Therefore, this would lead to reactivation of fetal hemoglobin (HbF) production that improves anemia and reduces the needs for transfusion.

OBJECTIVE:

To study miRNA-210 in the plasma of beta thalassemia patients and its relation to HbF level and disease severity.

SUBJECTS AND METHODS:

The study was carried out on 50 individuals divided into three groups. Group A included 30 thalassemia major patients, Group B included 10 thalassemia intermedia patients, and Group C is 10 healthy volunteers as control. All individuals underwent to history taking, physical examination, and laboratory investigations, complete blood count, serum ferritin, hemoglobin electrophoresis, and measurement of miRNA-210 expression levels in plasma of peripheral blood samples by quantitative real-time polymerase chain reaction.

RESULTS:

Examination of miRNA-210 plasma level among different groups revealed no statistically significant association between control and thalassemia group or its subgroups (Major and intermedia) (P = 0.224, P = 0.116, and P = 0.734, respectively). Moreover, miRNA-210 was slightly higher in responders than nonresponders to hydroxyurea but did not reach significant level.

CONCLUSION:

miRNA-210 levels were not associated with increase in HbF levels in thalassemia patients.

Published: September 2023

Congenital heart defects (CHDs), the most common major birth defects, undergo effective surgical care in the last decade, enhancing survival. After heart surgery, mechanical, infectious, and noninfectious causes induce pediatric pulmonary problems. Necrotizing enterocolitis and feeding intolerance are frequent digestive issues. Diuretics relieve fluid excess, but early dialysis may help in cardiac intensive care unit (CICU) patients. Cumulative insulin dosages improve postoperative hyperglycemia. Noncardiac organ system problems are common in current pediatric cardiac intensive care units including seizures needing anti-epileptics. While, managing the patients in CICU, one must consider noncardiac organ system integrity and function.

Background:

Patients admitted to critical care need timely interventions after evaluating all clinical parameters. This study aims to assess the impact of the comprehensive rounding checklist on physician compliance and patient-related outcomes in a multidisciplinary pediatric intensive care unit (PICU).

Subjects and Methods:

This prospective observational study was conducted in two phases over period of 2 months at multidisciplinary PICU from Pakistan. A structured rounding checklist of 35 components encompassing patient care was introduced and implemented in the PICU. During the preimplementation phase, a nurse took notes of relevant patient clinical details missed by the physician during the round, included them in the rounding checklist. And during the implementation phase, the nurse actively intervened when a physician did not discuss a particular component during the round. All components discussed were check marked.

Results:

The checklist was completed for 812 rounds (162 patients) in preimplementation and 2348 rounds (590 patients) in the postimplementation phase. Most frequently missed components in the preimplementation phase were checking for surgical site infection (8.9%), discharge plan (7.5%), deep vein thrombosis (DVT) prophylaxis (7.3%), and ventilator-associated pneumonia bundles (7.0%). Whereas, during the postimplementation phase, resident teaching (8.0%), discharge plan (7.2%), and DVT prophylaxis (6.5%) were most frequently missed. Hospital length of stay decreased from 4.5 ± 3.7 to 4.1 ± 2.9 days (P = 0.05), and overall mortality decreased from 19% to 11.4% (P < 0.05).

Conclusions:

Introducing the checklist with a prompter, improved physician compliance and patient-related outcomes in our PICU.

Published: September 2023

With an advancement in technology, the Internet of Things (IoT) has penetrated various domains such as smart buildings, intelligent transportation systems, healthcare, smart parking, air quality monitoring, water contamination identification, and supply chain owing to its ubiquitous nature. IoT devices periodically collect the data and send it to the gateway or server for pre-processing. However, the security offered in the IoT devices or gateways are still in a nascent stage. An Intrusion Detection System (IDS) meant for detecting the cyber threats on IoT should intercept most threats with minimum latency and yet be lightweight in nature. IoT devices also have low memory footprint which makes them resource constrained. This paper presents a framework built using a three-tier IoT architecture that successfully detects most attacks using machine learning approaches with an accuracy of 99%. Machine learning approaches are fed data using Apache Kafka to REST API. Sampling methods such as undersampling and adaptive synthetic sampling are applied to balance the imbalanced nature of the dataset. We examined the robustness of the approach using different samples with varying sizes and varying dimensions. Experimental results depict a superior performance of random forest over other approaches in terms of speed and accuracy.
The Effect of Synesthesia Metaphor Based on Synesthesia Value Attributes on Consumer Perceptual Value: Focusing on the service usage experience of low-cost airlines(LLC)
Authors:   Korea Institute of Design Research Society, Lee Jung Sun
Published: September 2023

Understanding consumer value has become an essential requirement for winning competition not only in the design field but also in the marketing field. This is because consumer value is expressed in the subconscious of a person's unconsciousness, and the unconscious is influenced by sensory stimulation and once the stimulation is received, it does not disappear. Accordingly, the purpose of this study is to confirm the influence of the brand experience situation on the consumer's value according to the synesthetic metaphor stimulation. For this purpose, an experimental study was conducted with low-cost airlines, which have contact points between physical and non-physical experiences in the service experience environment, as the research object. The research method was to conduct prior research on synesthesia metaphors based on literature research on synesthesia modality. In order to find synesthesia metaphors of value attributes that are influenced and influenced at the unconscious level, synesthesia value attributes (vision, hearing, action) were derived using the laddering technique, and synesthesia metaphors of three elements were used as independent variables (vision+hearing, vision+action, hearing+action), an experimental study was conducted with consumers' perceptual value as the dependent variable as the basis for setting the stimulus for the experimental study. Through experimental research through questionnaire evaluation, the synesthesia modality metaphor and its influence on consumers' perceptual value were confirmed through binary analysis. As a result of the study, the synesthesia modality metaphor did not have a more positive effect on consumer perceptual value than the unisensory modality metaphor. However, depending on the type of synesthesia metaphor, it has a more positive impact than unisensory stimulation, and ‘action metaphors’ have the highest impact in constructing synesthesia metaphors.

Therefore, in order to attract consumers, this study takes experience design as the theoretical basis and aims to investigate the influence of experience design characteristics (non-daily, interactive, dynamic and associative) on brand image and purchase intention in the design of sports brand flagship shop space. In order to meet the purpose of this study, two sports brand flagship shop spaces, NIKE and ADIDAS, were selected as investigation cases, and a questionnaire survey was carried out with the group of consumers visiting the sports brand flagship shops, and 302 valid questionnaires were finally returned, and the collected data were analysed by frequency analysis, reliability analysis, validation factor analysis, correlation analysis, and regression analysis using the statistical programs of SPSS26.0 and AMOS 24.0. analysis and regression analysis. The results of the study are as follows: (1) The spatial experience design characteristics of flagship shops of sports brands (non-routine, interactivity, dynamism and associativity) have a positive impact on brand image. (2) Brand image has a positive effect on consumers' purchase intention. The results of this study can provide empirical data and theoretical support for the spatial planning of sports brand flagship shops.

Authors:   Korea Institute of Design Research Society, jo yunkyung , kim minjung
Published: September 2023

This study analyzes and proposes the possibility of combining realistic media art and surrealistic expressive techniques. To do so, we first understand the types and characteristics of surrealistic expressive techniques. In particular, we focus on Alexandrian and Suzy Gablik's work on depaysment. Second, by collecting and analyzing examples of d’strict's works, we summarize the characteristics of depaysment network representation in realistic media art. Third, we propose how surrealistic expression techniques can be used to improve the artistry of realistic media art and design education. This study is limited to six works in the d’strict, and is conducted through the methods of literature review and case analysis. The results of the study showed that the characteristics of the depaysment network such as 'opening up the unknown dimension' and 'bringing life' were mainly utilized in the six realistic media artworks of the d’strict. In addition, various depaysment elements emphasize the core meaning of the artwork through visual impact, which confirms that depaysment features enhance the effectiveness of realistic media art. Finally, this study proposes a theoretical basis for how the characteristics of depaysment, one of the surrealistic expression techniques, can contribute to the development of media art production and design education in the future.

Accordingly, this study is meaningful in conducting in-depth interviews with five interior space realistic content experts and six interior designers working on realistic content and presenting plans and strategies for use in the interior design field through open coding and SWOT-PEST analysis frames. Analysis results: First, smooth communication takes place by using virtual simulation to help with complex concepts and understanding. Second, build an online/offline convergence learning environment by converging information and communication technology and artificial intelligence technology. Third, government policies are needed to support the public sector, such as government ministries and private companies/organizations, and to grow industries and expand their base. Fourth, inconvenient aspects such as device weight and size, portability, and high market price must be improved. Fifth, a mid- to long-term roadmap for the industry must be established and a differentiated industry ecosystem must be created. Lastly, it is necessary to establish a professional talent training system through cooperation between industry, academia, and research institutes. This study synthesized in-depth interviews to analyze the status, necessity, and implications of realistic content utilization, sought future directions and strategies, and suggested the possibility of industrial growth and the development of a foundation.

Published: September 2023

This study analyzed the media art space of teamLab based on Mihaly Csikszentmihalyi's immersion theory to find out the expressive characteristics of the media experience space and cognitive thinking. As a method of the study, the teamLab's works were first analyzed focusing on the characteristics derived from the consideration of immersion theory to interpret the relationship between the expressive elements of the media art space and the immersive characteristics according to spatial expression. As a result of the analysis, teamLab's works create new artistic experiences through the fusion of natural elements and media art, and various natural elements are organically harmonized within the work and induce various visual experiences through imaginary images to the audience. In addition, the spatial and spatial changes and distortion of boundaries of the work obscure the boundaries between the audience's reality and the work, causing new sensory experiences and participation. Through the study, the relationship between the characteristics of space and the expression elements that occur in the stage of immersion in teamLab's media art space was identified, and the possibility of multiple directions and organic expressions on the boundaries of perception expressed by virtual images that induce visual interaction. Research findings indicate that the immersive characteristics of media art prioritize the dissolution of boundaries and the formation of active communication within artworks. The fusion of nature and media art stimulates audience interest and provides fluid meaning, thereby creating immersive experiences.

Published: September 2023

Whether in the East or the West, all human beings wish for health and longevity. Since ancient times, the origin of longevity has been passed down through historical records and oral traditions. In the Joseon Dynasty, our nation developed a collection of items containing the expression of longevity. There are cultural assets such as clothes, furniture, and buildings with longevity patterns used in the royal family of the Joseon Dynasty. It is being reinterpreted by being grafted into many fields as a formative expression in art culture and contemporary design culture. This study investigated the preferences of modern people about animals and plants that wish for longevity, and developed textile design based on the results.

A Study on the Development and Compatibility of Decorative Art Tile based on 3D Unit Pattern System
Authors:   Korea Institute of Design Research Society, Ha Bong Soo
Published: September 2023

This study developed basic units such as cells and units based on the FDP design methodology with the product scalability of flexible design patterns (FDP) that simultaneously evoke images of order and change in mind, and verified the compatibility of design by combining cells of different shapes. The cells developed for verification are largely divided into straight lines and curves, lines and area shapes, and the colors are black, white, and yellow tricolors, which are combined with the same color, similar color, and contrast color. Combination methods were divided into isomorphism, similarity, and heteromorphic, and examined in connection with color. The deployment method was performed by comparing the regular deployment (configuration) of cells and units with the irregular deployment (configuration). As a result, most of the combinations of cells with different shapes were found to have visual effects of order, change, and unity. Above all, it was confirmed that the combination of shapes has a strong characteristic of inducing unity and harmony, and the contrast between black and white has a side that triggers a change.On the other hand, the visual effect of FDP is possible because of the division method based on golden division, the enhancement of connectivity using diagonal and connection pointer, and the symmetric manipulation. This formative technique is expected to be used as educational contents for experiential learning of basic molding in connection with 3D printing technology.

O tema armadilha da renda média apesar de recente apresenta diversos debates literários, todavia não há um consenso sobre como definir esse conceito. De acordo a literatura, a armadilha de renda média tem sido um termo utilizado na literatura recente com o objetivo de classificar economicamente os países que após conseguirem atingir uma economia intermediaria apresentam dificuldades para transpor essa linha. Neste sentido, o objetivo deste trabalho é investigar o que a literatura tem considerado como “armadilha da renda média” e quais as soluções teóricas propostas para proporcionar que os países que se encontram nessa situação, possa transpor esse limiar. O estudo foi realizado pelo método de revisão de literatura qualitativa, descritiva e de caráter exploratório. O que se pode evidenciar é que existem linhas de pensamentos teóricos que guiam argumentos para sobre a condição e auxiliar os países no manejo do seu crescimento. As duas principais linhas de pensamento hipotéticas abordadas nesse artigo foram a da ausência de mudança estrutural e os fatores para desaceleração do crescimento.
