Authors: KAPLAN Taha Yasin , YÜNER Berna
Published: December 2023

Çağdaş eğitim yönetimi yaklaşımları, okul yöneticilerinin çeşitli liderlik becerilerine sahip olmalarını beklemektedir. Bu becerilerden birisi de liderliğin uygun şartlarda, uygun kişilere dağıtılarak okul yönetiminin işbirliği içinde yapılmasıdır. Çağdaş yaklaşımlar liderliğin tüm paydaşlara uzmanlıklarına göre dağıtılmasını öne çıkmaktadır. Bu doğrultuda öğretmenlerin daha fazla sorumluluk alarak eğitim örgütlerini ileriye taşıyacakları, görevlere katılmada istekli olacakları yönetim ve karar alma süreçlerine katılmaları ile örgütsel bağlılıklarının artacağı öngörülmektedir. Bu çalışmada öğretmen görüşlerine göre ilköğretim okullarında görev yapan okul yöneticilerinin dağıtımcı liderlik davranışları ile öğretmenlerin örgütsel bağlılıkları arasındaki ilişkinin incelenmesi amaçlanmıştır. Araştırmada nicel araştırma yöntemlerinden ilişkisel tarama modeli kullanılmıştır. Elde edilen bulgulara göre Araştırmaya katılan öğretmenlerin okul müdürlerinin dağıtımcı liderlik davranışlarına ilişkin algıları ortalamanın üzerinde, örgütsel bağlılıkları ise orta düzeyde olduğu görülmüştür. Ayrıca dağıtımcı liderlik ile örgütsel bağlılık arasında pozitif yönlü orta düzeyde anlamlı bir ilişki bulunmuştur.

G106.3+2.7, commonly considered to be a composite supernova remnant (SNR), is characterized by a boomerang-shaped pulsar wind nebula (PWN) and two distinct (“head” and “tail”) regions in the radio band. A discovery of very-high-energy gamma-ray emission (E

γ
> 100 GeV) followed by the recent detection of ultrahigh-energy gamma-ray emission (E

γ
> 100 TeV) from the tail region suggests that G106.3+2.7 is a PeVatron candidate. We present a comprehensive multiwavelength study of the Boomerang PWN (100″ around PSR J2229+6114) using archival radio and Chandra data obtained two decades ago, a new NuSTAR X-ray observation from 2020, and upper limits on gamma-ray fluxes obtained by Fermi-LAT and VERITAS observatories. The NuSTAR observation allowed us to detect a 51.67 ms spin period from the pulsar PSR J2229+6114 and the PWN emission characterized by a power-law model with Γ = 1.52 ± 0.06 up to 20 keV. Contrary to the previous radio study by Kothes et al., we prefer a much lower PWN B-field (B ∼ 3 μG) and larger distance (d ∼ 8 kpc) based on (1) the nonvarying X-ray flux over the last two decades, (2) the energy-dependent X-ray size of the PWN resulting from synchrotron burn-off, and (3) the multiwavelength spectral energy distribution (SED) data. Our SED model suggests that the PWN is currently re-expanding after being compressed by the SNR reverse shock ∼1000 yr ago. In this case, the head region should be formed by GeV–TeV electrons injected earlier by the pulsar propagating into the low-density environment.
A New Insight into Electron Acceleration Properties from Theoretical Modeling of Double-peaked Radio Light Curves in Core-collapse Supernovae
Authors: Matsuoka Tomoki , Kimura Shigeo S. , Maeda Keiichi , Tanaka Masaomi
Published: December 2023

It is recognized that some core-collapse supernovae (SNe) show a double-peaked radio light curve within a few years since the explosion. A shell of circumstellar medium (CSM) detached from the SN progenitor has been considered to play a viable role in characterizing such a rebrightening of radio emission. Here, we propose another mechanism that can give rise to the double-peaked radio light curve in core-collapse SNe. The key ingredient in the present work is to expand the model for the evolution of the synchrotron spectral energy distribution (SED) to a generic form, including fast and slow cooling regimes, as guided by the widely accepted modeling scheme of gamma-ray burst afterglows. We show that even without introducing an additional CSM shell, the radio light curve would show a double-peaked morphology when the system becomes optically thin to synchrotron self-absorption at the observational frequency during the fast cooling regime. We can observe this double-peaked feature if the transition from the fast cooling to slow cooling regime occurs during the typical observational timescale of SNe. This situation is realized when the minimum Lorentz factor of injected electrons is initially large enough for the nonthermal electrons’ SED to be discrete from the thermal distribution. We propose SN 2007bg as a special case of double-peaked radio SNe that can be possibly explained by the presented scenario. Our model can serve as a potential diagnostic for electron acceleration properties in SNe.
The role of postoperative trimetazidine therapy in on-pump coronary artery bypass surgery
Authors: Stanev Kamen , Yaneva Antonia , Ivanov Asen , Gonovski Todor
Published: December 2023

Introduction: Coronary artery bypass surgery remains the gold standard in the treatment of patients with ischemic heart disease. However, the increased oxidative stress caused by the release of free radicals during the ischemia-reperfusion time is a well-known pathophysiological process during and after coronary revascularization procedures. It may lead to reversible and irreversible myocardial injury.

The focus of this prospective single-blinded randomized controlled trial is to investigate and analyze the effectiveness of the drug trimetazidine on reducing postoperative myocardial ischemia-reperfusion injury.

Aim: We evaluated the effects of trimetazidine on reactive oxygen species that may arise from myocardial ischemia-reperfusion period or systemic inflammation after coronary artery bypass grafting (CABG) surgery.

Materials and methods: The study included 90 patients divided into two groups who underwent elective coronary artery bypass surgery between March 2018 and October 2018. The patients in one of the groups received 35 mg trimetazidine twice daily as soon as they were extubated. The remainder of the pharmaceutical therapy was the same for all participants. Preoperative and postoperative levels of several blood-based biochemical markers including malondialdehyde (MDA), creatinine kinase-MB fraction (CK-MB) and high-sensitivity troponin T (hs-TnT) were measured. The data was classified and analyzed by the timing of sample collection.

Results: The results indicate that postoperative trimetazidine medication reduces MDA production, resulting in reduced oxidative stress and improved cardiac cell protection via antioxidant status augmentation. The follow-up was 6 months after the surgery. The Minnesota Living with Heart Failure Questionnaire was used to assess the quality of life of patients, and the results were excellent.

Conclusions: Postoperative trimetazidine therapy leads to improvement of the myocardial cell metabolism and thus reduction in post CABG ischemia-reperfusion injury.

Published: December 2023

Aim: The purpose of this study was to compare the mechanical properties of materials used for orthodontic retainers made by direct 3D printing and thermoforming.

Materials and methods: Twenty-one specimens (n=7) from 3 different materials (Formlabs Dental LT Clear V2 - Formlabs Inc., Somerville, Massachusetts, USA; NextDent Ortho Flex - Vertex-Dental B.V., Soesterberg, The Netherlands, and Erkodent Erkodur - ERKODENT, Germany) were manufactured and their mechanical properties were evaluated. Two of the specimen groups were 3D printed and the other one was fabricated using a material for thermoforming. The statistical methods we applied were descriptive statistics, the Kruskal-Wallis and Dunn’s post-hoc tests.

Results: With respect to Young’s modulus (E), the Kruskal-Wallis test (df=2, χ2=17.121, p=0.0002) showed a significant difference between the materials for direct 3D printing of orthodontic retainers (E=2762.4 MPa±115.16 MPa for group 1 and 2393.05 MPa±158.13 MPa for group 2) and thermoforming foils (group 3, E=1939.4 MPa±74.18 MPa). Statistically significant differences were also found between the flexural strength (FS) (Kruskal-Wallis test, df=2, χ2=17.818, p=0.0001) and F(max) (Kruskal-Wallis test, df=2, χ2=17.818, p=0.0001).

Conclusions: The materials tested in the current study showed statistically significant differences in their Young’s modulus, flexural strength, and F(max).
Déflexion, philosophie et terrain
Authors: Raïd Layla
Published: December 2023

Je propose d’éclairer les philosophies de terrain à partir du concept de déflexion développé par Cora Diamond. La pensée défléchit quand elle ne peut pas embrasser une réalité difficile, défiant ses pouvoirs de compréhension. Je décris la déflexion en m’appuyant sur l’analyse d’œuvres littéraires proposée par Diamond (Hughes, Coetzee). Je présente ensuite les philosophies de terrain comme animées par un refus de la déflexion et par un désir de s’exposer d’une manière nouvelle. Je décris, en dernière partie, la pensée écologique de Val Plumwood comme une telle philosophie de terrain.
Les circonstances changeantes de l’inflation
Authors: Ferrand Denis
Published: December 2023

Après des années à en déplorer la disparition, les banques centrales n’ont pu que constater le retour en force de l’inflation au sortir des périodes de confinement de la population et d’arrêt brutal de l’économie en 2020. La question du caractère durable ou transitoire de cette résurgence de l’inflation a alimenté dans un premier temps les débats. Perçue initialement comme transitoire, en particulier en Europe, ce qui a retardé les réactions de politiques monétaires pour la juguler, cette inflation issue de chocs initiaux de nature exogène a progressivement déclenché des boucles de réaction de l’économie qui en ont renforcé le caractère durable. Au-delà des circonstances de court terme qui ont modelé l’évolution des prix, nous examinons dans ce papier dans quelle mesure le référentiel d’inflation peut être plus durablement bouleversé par les cicatrices que cet épisode pourrait laisser. Apporter des éléments de réponse à cette question invite à décomposer le processus inflationniste en différentes phases qui le caractérisent. La résurgence d’inflation au lendemain des déconfinements a été la conséquence des profonds déséquilibres entre offre et demande qui se sont manifestés alors à l’échelle mondiale. Cette première phase est close ou presque. Elle a été suffisamment prolongée pour que l’inflation procède désormais également d’effets de second tour liés à l’accélération des revenus nominaux. Plusieurs trimestres de taux d’intérêt réels positifs et de croissance inférieure à sa tendance seraient probablement nécessaires pour que ces tensions inflationnistes s’apaisent. La première de ces conditions n’étant pas atteinte et des déterminants plus structurels s’affirmant, l’inflation serait durablement plus élevée que lors de la période antérieure à la pandémie.
Du tiers employeur au tiers-lieu territorial d’emploi ? Le groupement d’employeurs
Authors: Angelergues Gaëlle , Condomines Bérangère
Published: December 2023

Cette étude vise à mettre en lumière le développement de l’usage élargi voire ambigu de la notion de tiers-lieu (TL). À partir d’une revue de littérature, les évolutions des dimensions constitutives du TL sont identifiées, amenant à proposer le terme de Tiers-Lieu territorial d’emploi. Agissant comme un acteur collectif territorialisé, le TL tend à être assimilé à d’autres pratiques de GRH territoriale comme le groupement d’employeurs, sans en offrir les mêmes garanties aux travailleurs. En se référant aux perceptions des différentes parties prenantes agissant au sein d’un groupement d’employeurs (GE, entreprises adhérentes, salariés), nous mettons en perspective les notions de TL et d’action collective territorialisée tout en indiquant le rôle spécifique de ce tiers employeur.

Aristotle’s theory of time is not flawed
Authors: Detel Wolfgang
Published: December 2023

Dans l’histoire de la philosophie et des sciences, Aristote a été le premier à élaborer une théorie du temps. Cette théorie, telle qu’elle est présentée en Physique IV 10-14 et VI 2, soulève de nombreuses questions et semble comporter un certain nombre d’énigmes. Toute tentative de lui donner un sens est alourdie par sa complexité et sa présentation souvent cryptique. La plupart des spécialistes modernes pensent que la théorie du temps d’Aristote est imparfaite. Ils se plaignent notamment que cette théorie est incohérente, qu’elle manque d’unité systématique, qu’elle échoue dans sa tentative de déduire les propriétés du temps à partir des propriétés de l’espace et du mouvement, et qu’elle n’explique pas la flèche du temps. Cet article cherche à montrer que ces objections ne sont pas fondées. Selon la nouvelle lecture de Physique IV 10-14 et VI 2 proposée dans l’article qui suit, la théorie du temps d’Aristote est logiquement cohérente, présente une structure logique sophistiquée qui n’est pas strictement déductive, éclaire la flèche du temps et fournit une synthèse du temps dit subjectif et objectif. L’annexe présente une comparaison entre la théorie du temps d’Aristote et la théorie du temps de la physique contemporaine sur la théorie objective du temps et de la psychologie cognitive contemporaine sur la théorie subjective du temps.
La finalité comme ἔργον dans le livre IV des Météorologiques d’Aristote
Authors: Gilberto dos Santos Nélio
Published: December 2023

Peut-on attribuer une finalité aux réalités les plus fondamentales et matérielles de la nature selon la téléologie aristotélicienne ? La réponse est apparemment affirmative d’après le livre IV, 12 des Météorologiques d’Aristote. Ayant entamé une recherche sur les corps homéomères du point de vue de la forme – manifestée par leurs finalités en tant que ἔργoν –, ce texte affirme que les artefacts, les organismes et leurs parties anhoméomères tout comme les homéomères, et même les éléments, bref « tout est déterminé par son ἔργoν ». Pourquoi Aristote emploie-t-il le terme ἔργoν, et quel est son sens dans le contexte de la téléologie naturelle ? Dans cette étude, nous proposons de laisser de côté le sens véhiculé par la traduction courante « fonction », à savoir le rôle joué par une réalité, ou une partie, pour le bien d’un tiers ou pour une totalité, pour la raison évidente que la causalité de la fin chez Aristote est sans conteste immanente, à savoir la réalisation de la forme de la réalité naturelle elle-même. Ainsi, le sens proposé de la fin-ἔργoν sera non pas externe, mais plutôt celui de mise en usage de la réalité en processus elle-même, fondée sur la dualité téléologique τὸ oὗ et τὸ ᾧ, où la fin oὗ est comprise comme étant la constitution d’une réalité, tandis que la fin ᾧ n’a plus le sens de bénéficiaire externe, mais renvoie à l’aspect dynamique de la forme, c’est-à-dire comme étant le dernier accomplissement de l’essence de la réalité une fois constituée.
Self-adaptive attention fusion for multimodal aspect-based sentiment analysis
Authors: Wang Ziyue , Guo Junjun
Published: December 2023

Multimodal aspect term extraction (MATE) and multimodal aspect-oriented sentiment classification (MASC) are two crucial subtasks in multimodal sentiment analysis. The use of pretrained generative models has attracted increasing attention in aspect-based sentiment analysis (ABSA). However, the inherent semantic gap between textual and visual modalities poses a challenge in transferring text-based generative pretraining models to image-text multimodal sentiment analysis tasks. To tackle this issue, this paper proposes a self-adaptive cross-modal attention fusion architecture for joint multimodal aspect-based sentiment analysis (JMABSA), which is a generative model based on an image-text selective fusion mechanism that aims to bridge the semantic gap between text and image representations and adaptively transfer a textual-based pretraining model to the multimodal JMASA task. We conducted extensive experiments on two benchmark datasets, and the experimental results show that our model significantly outperforms other state of the art approaches by a significant margin.
Encouraging green infrastructure at Ontario universities: What's policy got to do with it?
Authors: Eves Erika , Walker Chad
Published: December 2023

In this paper, and via a case study in Waterloo, we explore policy's role in encouraging green infrastructure (GI) adoption in Ontario universities. More specifically, we evaluate the relationship between policy and GI, and determine the policy level required to successfully implement GI. We employed a qualitative research approach of semi-structured, open-ended interviews (n = 8) to understand better participants' views towards existing GI policies and frameworks. We find that multi-level government collaboration, regulatory frameworks and incentives and funding mechanisms are key themes influencing GI adoption. Interviews revealed that municipal incentives are essential in encouraging GI implementation on a local scale. However, federal and provincial factors are also crucial for the long-term establishment of GI. We conclude that policy is essential, and that multi-level collaboration is required to implement GI across Ontario's universities. With little published research there is in this area suggests the importance of government policy, especially at the municipal level, in terms of getting GI projects built. Yet, there are key gaps in our understanding, including the role of provincial and federal policy.

Published: December 2023

Congenital adrenal hyperplasia (CAH) is a common endocrine disorder that can lead to poor quality of life and the development of adrenal and extra-adrenal mass lesions when poorly controlled. Adrenal myelolipomas are rare, benign neoplasms that have been observed in long-standing, uncontrolled CAH cases. In this report, we describe a 31-year-old patient with ambiguous genitalia, hypokalemia, and normotension. The hormonal profile showed elevated 11-deoxy cortisol and 17-hydroxy progesterone. The clinical and biochemical profile was suggestive of CAH due to 11-beta-hydroxylase deficiency. On evaluation for pain abdomen, bilateral large adrenal myelolipomas were found for which surgery was done. Presently the index case is on steroid replacement therapy. This case emphasizes the importance of timely diagnosis adherence to treatment and appropriate follow-up of CAH cases in order to prevent the development of adrenal myelolipomas.

Published: December 2023

Maturity-onset diabetes of the young (MODY) is the most common cause of monogenic diabetes, having 14 subtypes. Amongst MODY, MODY-5 accounts for less than 5% of cases. Along with diabetes, it presents with a number of extra-pancreatic manifestations. We report a case of a 15-year-old boy with diabetes, renal dysfunction, and obstructive uropathy. This presentation along with lean phenotype, absence of ketosis, and features of insulin resistance with a relatively preserved beta cell function suggested a diagnosis of MODY. This was later confirmed by genetic analysis. The patient progressed to develop chronic kidney disease and was managed with insulin therapy with interventions for obstructive uropathy.
An Exploratory Study of Cervical Vestibular-Evoked Myogenic Potential in Users of Personal Listening Devices
Authors: Dessai Teja Deepak , Bhat Rashmi J. , Kumar Kaushlendra
Published: December 2023

Context:

The use of personal listening devices (PLDs) is becoming increasingly popular, particularly among young people. Numerous studies have demonstrated that being exposed to PLDs can have adverse effects on the auditory system. Owing to the similarities between the auditory and vestibular systems, it is possible that the negative effects of PLD use may extend to the vestibular system, an area that has not been extensively studied.

Aim:

The study aimed to investigate the impact of exposure to PLDs on the vestibular system, specifically the sacculo-collic reflex assessed by the cervical vestibular-evoked myogenic potential.

Settings and Design:

The current study used a cross-sectional study design.

Materials and Methods:

A total of 80 participants were divided into four groups based on the history of PLD exposure. Each group consisted of 20 participants who underwent cervical vestibular-evoked myogenic potential (cVEMP) testing using alternating polarity 500 Hz tone bursts.

Statistical Analysis Used:

Analysis of variance (ANOVA) and Bonferroni post hoc test were used to obtain the statistically significant difference among the group.

Results:

The results showed that the amplitude of p1-n1 of cVEMP was significantly reduced in individuals with longer PLD exposure duration.

Conclusion:

The study suggests that listening to music through a PLD at high levels of volume controls could be deleterious to the vestibular well-being of an individual. The study highlights the importance of being aware of the adverse effects of using PLDs to prevent potential damage to the vestibular systems.
The Role of Noise Annoyance and Noise Sensitivity in the Effect of Aircraft Noise on Self-Reported Health
Authors: Kodji Minon′tsikpo Kossi , Lanoy Émilie , Giorgis-Allemand Lise , Laumon Bernard , Evrard Anne-Sophie
Published: December 2023

Background:

Transportation noise seems to impair self-reported health status (SRHS). However, only a few studies have considered the role of noise annoyance and noise sensitivity in this deleterious effect. This study aims investigating mediator and moderator roles of noise annoyance and noise sensitivity.

Methods:

In 2013, the DEBATS longitudinal study included 1244 participants aged over 18 years and living around three French airports. These participants were followed up in 2015 and 2017. They self-reported their perceived health status, aircraft noise annoyance, and their noise sensitivity via a questionnaire during the three visits. Noise maps were used to estimate aircraft noise levels at the facade of participants’ residence. Generalized linear mixed models with a random intercept at the participant level were used.

Results:

Aircraft noise levels were associated with severe annoyance. Severe annoyance tent to be associated with impaired SRHS. Aircraft noise levels were associated with impaired SRHS only in men (odds ratio [OR] = 1.47, 95% confidence interval [CI] = [1.02, 2.11], for a 10-dBA L
den increase in aircraft noise levels) with a weaker association adjusted for annoyance (OR = 1.36, 95% CI = [0.94, 1.98]). The association was stronger in men who reported high noise sensitivity (OR = 1.84, 95% CI = [0.92, 3.70], versus OR = 1.39, 95% CI = [0.90, 2.14], for men who were not highly sensitive to noise).

Conclusion:

From our results, the deleterious effect of aircraft noise on SRHS could be mediated by noise annoyance and moderated by noise sensitivity. Further studies using causal inference methods are needed for identifying causal effect of exposure, mediator, and moderator.
The Effect of Noise Exposure on Hearing Function and Vestibular Evoked Myogenic Potentials
Authors: Cetinbag-Kuzu Ozgenur , Bahadir Hande , Guneri Enis Alpin , Cimrin Arif Hikmet , Kirkim Gunay
Published: December 2023

Purpose:

Exposure to noise can cause damage to both auditory and vestibular systems. The objective of this study is to evaluate how noise exposure affects the hearing and vestibular systems in individuals with noise-induced hearing loss (NIHL).

Methods:

This study included 80 subjects (40 subjects with NIHL, and 40 controls), between 26 and 59 years old. For hearing assessment, pure-tone audiometry, extended high-frequency audiometry, tympanometry, acoustic reflex threshold, and distortion product otoacoustic emission tests were used; for vestibular assessment, the cervical and ocular vestibular evoked myogenic potentials tests were used.

Results:

Statistically significant differences were found between the two groups in 3 to 6 kHz frequency thresholds; in extended high-frequency audiometry tests, there were also significant differences between groups at all frequencies from 9.5 to 16 kHz. The cervical and ocular vestibular evoked myogenic potentials thresholds were significantly higher and N1-P1 amplitudes were significantly lower in the NIHL group.

Conclusion:

Noise can lead to damage to both auditory and vestibular functions. Therefore, audiological assessments and vestibular evoked myogenic potentials could be clinically useful for examining patients with NIHL.

AI is just beginning to be integrated into clinical medicine, and will continue to be integrated into clinical care. ChatGPT has already been used in ophthalmology to triage symptoms, write operative notes, answer ophthalmic board-exam level questions and for medical education. GPT-4 builds upon the abilities of the prior GPT models by delivering more sophisticated natural language processing capacities, making it an AI technology with high potential application for medical imaging analysis. We wanted to examine GPT-4’s ability to interpret ophthalmic images. Although GPT-4 remains a promising start to the future of ophthalmic imaging analysis, further research and modifications will be necessary before the technology can be used for high stakes clinical encounters in human patients.

Recommendations could be useful to guide institutions planning to incorporate simulation-based education (SBE) into their training programs or institutions that have an established program but want to benchmark it against best practices. An effective, inclusive, and enjoyable simulation learning environment must be created to optimize learning and skills development. Areas to consider when proposing recommendations for creating an effective SBE environment include the following: the environment, group learning, facilitators, and educational requirements. The common pitfalls in simulation design when simulations are not effective include inadequate prebriefing, cognitive overload, poor alignment with the real-world context or task, inadequate debriefing, and insufficient time for debriefing. The ethical imperatives of SBE must inform the training programs. The role players in the shared ethical values when using SBE include the patients, students, simulationists, and the simulators and simulated patients. SBE programs must be embedded into a curriculum and should not be an optional add-on. To ensure high standards of training in simulation centers, these centers must adhere to specific accreditation standards. SBE aims to create a better training environment, improve patient safety, and address the challenges regarding the training platform and the burden of disease in eye care globally. Surgical simulation in ophthalmology provides an opportunity for partnership between institutions nationally and across borders because simulation centers cannot function in isolation. Recommendations for creating collaborations and partnerships for surgical simulation training will enhance the impact of any eye care program.

Authors: Kumarasamy Murugan , Palani Subashree , Subramaniam Gnaneswaran
Published: December 2023

Purpose:

To study the perioperative profile of pseudoexfoliation (PXF) among the camp patients who underwent cataract surgery.

Methods:

This retrospective study was conducted among camp patients with PXF, who underwent cataract surgery in a tertiary care centre. Anterior segment examination including distribution of PXF material over anterior segment structures, pupillary dilatation, gonioscopy, applanation tonometry, intraoperative and postoperative complications, and subsequent management were all documented from the records.

Results:

A total of 1985 patients underwent cataract surgery between November 2016 and October 2019 of which PXF was recorded in 140 (7%) patients. 49 patients had bilateral PXF, while 83 patients had unilateral PXF. 50% (91/181) of eyes had PXF on anterior lens capsule and pupillary border and 67% (113/167) of eyes had both cortical and nuclear cataracts simultaneously. Intraocular pressure (IOP) was significantly elevated in PXF eye of unilateral PXF patients. The prevalence of PXF glaucoma in our study population was 2.8%. 16.7% (22/132) of patients had intraoperative complications of which posterior capsule rent (PCR) occurred more in bilateral PXF patients and zonular dehiscence (ZD) was seen more in unilateral PXF patients. Postoperatively, surge in anterior segment inflammation was noted from 8% on the first day to 11% at the end of the first week.

Conclusions:

PXF eyes require meticulous preoperative examinations and intraoperative handling to prevent complications like ZD and PCR. Following cataract surgery, these patients require frequent follow-up visits in the initial two weeks of postoperative period to address the surge in anterior chamber reactions.

Cataract surgery is one of the most commonly performed ophthalmic surgeries worldwide. Stromal hydration is done to improve the integrity of the wound, reform the anterior chamber at the end of the surgery and obtain a water-tight wound closure to reduce the risk of endophthalmitis. At the completion of the surgery, subconjunctival injections of antibiotics and steroids are commonly given to reduce the risk of endophthalmitis. Intracameral injection of antibiotics is the delivery of drugs to prevent endophthalmitis, but if a wrong drug is injected in the anterior chamber, it can result in endothelial and anterior chamber toxicity. Here we report a rare and interesting case of a 60-year-old female who underwent manual small-incision cataract surgery (MSICS) for nuclear sclerosis grade 3. All the steps of the surgery were uneventful. At the end of the surgery, side port stromal hydration was performed, and while injecting intracameral moxifloxacin wrongly, gentamicin and dexamethasone were injected into the stroma and anterior chamber. The patient developed 3 + striate keratopathy postoperatively, which was managed with tapering doses of topical steroids, hypertonic saline, and adjuvant drugs. The endothelial cell toxicity resolved within three weeks, and the patient’s vision returned to 6/6. This case signifies that an intraoperatively wrong drug can be injected intracamerally, resulting in transient endothelial cell toxicity, which, if managed correctly, can give an excellent outcome.

RESUMEN Introducción El presente estudio analiza el uso que las principales organizaciones del tercer sector de Chile y España hacen de sus perfiles en Facebook e Instagram. En concreto se estudia cómo gestionan su presencia pública en estas redes sociales, en qué asuntos centran su actividad, cómo están conectando con sus públicos y el nivel de confianza que proyectan. Metodología: se ha utilizado el análisis de contenido de las publicaciones realizadas por 50 ONGs durante 1 mes, tomando en consideración variables cuantitativas y cualitativas; la muestra ha estado formada por 25 organizaciones de cada país, seleccionadas mediante un muestreo no probabilístico de acuerdo a criterios predefinidos. Resultados: se han analizado un total de 2.103 publicaciones, que muestran que Facebook es la red más utilizada, especialmente en España,y también la red con más número de seguidores; el uso que las ONG le dan a sus perfiles es fundamentalmente informativo, pero existen diferencias entre España y Chile y también por sector de actividad de las organizaciones; el formato más utilizado para postear es el texto y notable el uso de hashtags; los temas más habituales tratan las actividadesy proyectos de las OTS con un tono formal. Discusión: tomando en consideración el carácter social y la necesidad de generar diálogo y conexión con la sociedad, las OTS deberían hacer más esfuerzo en sus perfiles de redes sociales dado el alcance y su potencialidad para la generación de engagement y confianza con sus públicos. Conclusiones: las estrategias de comunicación de las ONGs en redes sociales no aprovechan el poder que tienen el canal para el diálogo y establecimiento de relaciones sociales con sus públicos

Improving the quality of malaria clinical case management in health facilities is key to improving health outcomes in patients. The U.S. President’s Malaria Initiative Impact Malaria Project has supported implementation of the Outreach Training and Supportive Supervision (OTSS) approach in 11 African countries to improve the quality of malaria care in health facilities through the collection and analysis of observation-based data on health facility readiness and health provider competency in malaria case management. We conducted a secondary analysis of longitudinal data collected during routine supervision in Cameroon (April 2021–March 2022), Mali (October 2020–December 2021), and Niger (November 2020–September 2021) using digitized checklists to assess how service readiness affects health worker competencies in managing patients with fever correctly and providing those with confirmed uncomplicated malaria cases with appropriate treatment and referral. Linear or logistic regression analyses were conducted to assess the effect of facility readiness and its components on observed health worker competencies. All countries demonstrated significant associations between health facility readiness and malaria case management competencies. Data from three rounds of OTSS visits in Cameroon, Mali, and Niger showed a statistically significant positive association between greater facility readiness scores (including the availability of commodities, materials, and trained staff) and health worker competency in case management. These findings provide evidence that health worker performance is likely affected by the tools and training available to them. These results reinforce the need for necessary tools and properly trained staff if high-quality malaria case management services are to be delivered at health facilities.
La contrainte selon l’Oulipo : anomalie de définition ou stratégie de légitimation
Authors: Xia Yuhua
Published: December 2023

The Oulipian Constraint: Anomalous Definition or Strategy of Legitimation?

The concept of “constraint” is central to Oulipo’s work, yet the group has introduced this term into modern literary criticism without providing a consistent definition. The resulting ambiguities create challenges for researchers studying Oulipian constraints. This paper reviews Oulipo’s attempts to theorize constraint and legitimize its literature, examining these efforts through the lens of the group’s struggle for literary legitimacy. Indeed, the concept of constraint represents not only Oulipo’s poetic uniqueness, but also an important tool for the group to legitimize itself and gain power within the literary field. This paper argues that “constraint” has served as both an expression of Oulipo’s aesthetic singularity and a strategic lever in its bid for legitimacy.

This study aims to explore techniques for eliciting emotional empathy in data visualization. To achieve this, it utilizes preceding research to derive tools for measuring levels of empathy, and analyzes the impact of different types of data visualization on empathy and charitable behaviors to develop a humanism-based data design strategy. The methodology encompasses both literature review and empirical research, reviewing 11 previous studies to identify the types of data visualization and tools for empathy measurement. For empirical analysis, four types of visualizations were created and subjected to an online survey with 95 Korean adults between April 10 to 15, 2023. The analysis revealed that the type of data visualization significantly influences the viewer's emotional response and charitable actions. Notably, realistic illustration elicited the highest level of empathy, while metaphorical infographics induced moderate levels of empathy and donations. This research provides valuable insights for establishing data visualization strategies grounded in humanism.

Authors:   Korea Institute of Design Research Society, Lee Ji Hyun , Jang Young Ho
Published: December 2023

With the enactment of the Special Act on the Improvement and Support of Old Planned Cities in 2023, we faced a new change in the urban structure, starting with the first new city that was conducted to solve the problem of housing shortage. In urban development aimed at solving the problem of simple housing shortage in the past, it is argued that a new paradigm is needed that reflects the purpose of public design aimed at improving the quality of life of individuals, ensuring national dignity, and basic security. This study is a basic study on reflecting urban development plans in the field of public design that were overlooked in the initial planning stage. The purpose of this study is to examine the development trends of cities in Korea and to analyze the current status and direction of public design promotion plans in four representative cities in each period. Based on the contents of this study, we would like to conduct a follow-up study reflecting this in the future to suggest ways to diversify the public design system that should be applied differently depending on the structural background and development method that our city can accept.

Authors:   Korea Institute of Design Research Society, Park Ji Young , Lee Sang Yong
Published: December 2023

The purpose of this study is to discover that non-face-to-face dailyization is leading to information acquisition, communication, and purchase through online platforms, and to analyze consumer perceptions of ceramic crafts' online platforms to present purchasing determinants. The framework of the analysis for this was based on the '7P Marketing Mix Strategy', and the items were subdivided and measured into a total of 15 items. In addition, through comparison based on nationality differences, the factors of purchasing decisions based on differences in preference and importance were analyzed for Koreans and foreigners (Chinese). According to the analysis based on the statistics calculated, there was a difference in preference and importance of Koreans and foreigners (Chinese), and there was no difference in product design and color preferred by nationality, gender, and age. The most important factors in purchasing decisions were found to have the greatest influence on “artistry and aesthetics,” while “reliability” (78%) was found to have an effect on factors that hinder purchasing decisions.

Authors:   Korea Institute of Design Research Society, Sun Xue Tong , Jung Jung Ho
Published: December 2023

With the rapid growth of virtual reality technology along with the Fourth Industrial Revolution, various experience contents based on metaverse are emerging. At the same time, metaverse online exhibitions are growing. However, there is a lack of evaluation studies related to user experience in metaverse experiential exhibitions. Therefore, it is necessary to explore new UX design evaluation factors based on metaverse. The purpose of this study is to establish metaverse-based experiential exhibition UX design evaluation factors and find directions for design improvement. The method of this study is, first, to derive metaverse-based experiential UX design evaluation factors through prior research, and second, to derive the importance of each evaluation factor using AHP techniques. Finally, IPA techniques are combined to measure user satisfaction and compare the importance derived from AHP techniques to suggest the direction of improvement of metaverse experiential exhibition UX design. The experimental results showed that the overall importance ranking for each element was reality, reliability, accessibility, usefulness, immersion, value, aesthetics, attractiveness, adaptability, and searchability. By synthesizing the experimental results of this study, we propose metaverse-based experiential exhibition UX design evaluation factors and present a more systematic and convergent evaluation method than existing studies. This study is expected to help provide theoretical support and practical grounds for future research related to metaverse experiential exhibition UX design.
A study on the impact of serving robot design attributes and usage variables on continuance usage intention: focusing on the S-O-R framework
Authors:   Korea Institute of Design Research Society, Hwang In Hee
Published: December 2023

This study was conducted to identify positive and negative perspectives that should be considered in the design process of serving robots and to derive directions for improving the customer experience process. The S-O-R framework was applied to reclassify attributes into functional and emotional design elements of serving robots and derive usage variables based on innovation resistance theory. For O, we applied use satisfaction, which is psychologically evaluated in the process of using a serving robot, and for R, we applied continuous use intention. The results showed that the key factors of serving robot design are usability and playfulness, factors that constitute extrinsic value are related to use satisfaction and influence, and convenience factors are related to perceived value and influence. Recently, serving robots are trying to expand additional functions and emotional approaches, so it is expected that the presentation of design attributes can help strengthen product competitiveness.
