Authors: Zhu Guang-Yu , Lu Jian , Wang Chao , Guo Jin-He
Published: March 2023

Aim:

To evaluate whether a novel irradiation stent (NIS) could decrease the rate of recurrent dysphagia, compared to the conventional irradiation stent (CIS) in patients with malignant dysphagia.

Materials and Methods:

We performed an open-label randomized controlled trial of participants with malignant dysphagia. A total of 94 participants were parallelly allocated into the NIS group or the NIS group between April 2019 and April 2020. The primary endpoint was the rate of recurrent dysphagia. The secondary endpoints included technical success, clinical success, overall survival, and adverse events.

Results:

The technical success rate and the clinical success rate was 100.0% (47/47) in both groups. The median follow-up period was 189 days (range 14–422 days). Recurrent dysphagia was observed in 12.8% (6/47) of patients in the NIS group and 31.9% (15/47) in the CIS group (P = 0.026). Tissue/tumor growth occurred in 4 patients (8.5%) after NIS placement and 12 (25.5%) after CIS placement (P = 0.028). Stent migration occurred in 2 patients (4.3%) after NIS placement and 3 (6.4%) after CIS placement (P = 0.646). No food obstruction was found in both groups. The median overall survival was 177 days (95% confidence interval [CI] 139–214) in the NIS group and 168 days (95% CI 153–183) in the CIS group (P = 0.932). The incidence of severe adverse events was comparable between the two groups (21.3% vs. 17.0%, P = 0.600).

Conclusions:

In patients with malignant dysphagia, compared with CIS, NIS could decrease the rate of tissue/tumor growth without increase the rate of stent migration and therefore decrease the rate of recurrent dysphagia.

Authors: Li Zhen-Yu , Wu Zhi-Yuan , Wu Wen-Jie , Shi Yan , Zhou Xing-Hong , Zhang Jie
Published: March 2023

Purpose:

Variability in volume delineation is a possible error source in brachytherapy. This study assessed the interobserver variations in clinical target volume (CTV) delineation in postoperative adjuvant 125I seed implant brachytherapy after parotid gland cancer surgical resection and evaluated the image fusion technique for target volume delineation.

Material and Methods:

Five radiation oncologists delineated gross tumor volume (GTV) and CTV in 20 patients using conventional delineation and image fusion methods. The consistency in target volume delineation was determined on the basis of differences between the oncologists. Variability was determined using Kendall's W-test, the mean conformity index (CI), the mean distance to conformity (MDC), and the center of gravity distance (CGD).

Results:

There were significant variations in the delineated target volumes among radiation oncologists, but the CTV consistency was significantly enhanced using the image fusion technique, based on Kendall's W, mean CI, average MDC, and average CGD, which were 0.752, 0.41, 2.75, and 4.997, respectively, using the conventional method, and 0.987, 0.86, 0.55, and 1.27, respectively, using the image fusion method.

Conclusions:

The interobserver variation in the delineation of the postoperative parotid target volume is large, but it can be considerably decreased using image fusion technology, which resulted in a noticeable improvement in the delineation precision of the target volume for parotid gland cancer. Thus, this technology can enhance the efficacy of 125I seed implant brachytherapy and decrease any adverse effects induced by errors in target delineation.

Authors: Zhao Chunchun , Li Kai , Zhu Mujia , Wang Fei , Zhang Ke , Fan Caibin , Wang Jianqing
Published: March 2023

Context:

Bladder cancer is one of the most common malignancies worldwide. Some studies noted sex differences in the prognosis of bladder cancer, but results are inconsistent.

Subjects and Methods:

In this study, we assessed whether women with bladder cancer exhibit a worse prognosis, after adjustment for disease stage, age, and body mass index (BMI), using clinical data from The Cancer Genome Atlas. We used a Student's t-test to compare age and BMI in groups with different sexes.

Statistical Analysis Used:

The Kaplan–Meier method with log-rank test was used to determine clinical prognosis.

Results:

The BMI (30.15 vs. 26.68, P = 0.0035) and age (67.54 years vs. 66.01 years, P = 0.045) of female patients with muscle-invasive bladder cancer (MIBC) were higher than those of male patients. The overall survival (OS) prognosis of female patients was worse than that of male patients. After grouping by disease characteristics, the disease-free survival (DFS) and OS prognoses of female patients under 60 years of age were worse than those of male patients. In the group with BMI >24, the OS prognosis of female patients was worse than that of male patients, but no difference was found in DFS prognosis. In the group with BMI ≤24, the DFS prognosis of female patients was worse than that of male patients, but no difference was found in OS prognosis. Compared to males, female patients with Stage III disease demonstrated a worse DFS prognosis and poorer OS prognosis, women with stage T3 demonstrated a worse DFS prognosis, and women with stage N0 demonstrated a poorer OS prognosis. No difference was found in prognosis between male and female patients in all other groups.

Conclusions:

In patients with MIBC, women tended to exhibit a worse prognosis than men. More specifically, we found a correlation between prognosis and sex after grouping patients by BMI.

Authors: Li Kuo , Li Chengqiang , Zhu Ting , Chen Jinhu , Cao Wentao , Yin Yong , Ma Changsheng
Published: March 2023

Objective:

Halcyon accelerator applies the flattening filter (FF)-free mode instead of the lead gate and FF treatment mode for traditional C-type accelerators. We aimed at comparing and analyzing the quality and delivery of nasopharyngeal carcinoma (NPC) plans between Halcyon and VitalBeam (VB) accelerators in fixed-field intensity-modulated radiation therapy (IMRT).

Methods:

The IMRT plans for thirty patients with NPC who had received radiotherapy were optimized using the VB (Plan VB) and Halcyon (Plan H) accelerators. Quality assurance verification was then conducted. The dose coverage of the planning target volume (PTV) and organs at risk (OARs), monitor units (MUs), and delivery time were analyzed for each plan.

Results:

All PTV and OAR indexes of Plan H and Plan VB met the clinical requirements. In the exposure dose of bilateral optic nerves between Plan H and Plan VB, no difference was found. The maximum dose of the lens, brainstem, spinal cord were 1.13 Gy, 1.36 Gy, 1.35 Gy, 2.82 Gy lower than the plan using VB , and the mean dose of the parotid glands were 3.82 Gy, 5.56 Gy lower than the plan using VB respectively, and an insignificant difference was found in the brainstem (P > 0.05). The MU for Plan H (22.92 ± 1.58 Gy) was higher than that for Plan VB (19.69 ± 4.52 Gy), and the difference was significant (P < 0.05).

Conclusions:

The treatment plans designed by Halcyon can meet clinical requirements with better protection for OARs and show advantages over VB in the dosimetry of NPC IMRT plans.

Published: March 2023

Sleep is an essential biological function of our life. The duration and pattern of sleep varies from animals to animals. We human beings sleep nearly 6 to 8 hours during night time. This consolidated night time sleep pattern normally achieved at around 4 years of age and continues thereafter. It is seen that sleep has an important role in overall growth and cognitive development of the child. Any disturbances in quality or duration of sleep in childhood may predispose the child to many physical and mental disorders in later ages. Some of the childhood sleep disorders resolve spontaneously, some resolve with age and some may persist throughout the life as a genetic burden. On the other hand many of the mental disorders of childhood and adolescent affect the sleep pattern of the individual. Substance abuse in adolescents is a challenging situation where unhealthy sleep pattern considered having a great role. This review article is meant to focus how sleep disturbances in childhood can predispose to mental illness and in turn how various mental disorders affect the normal sleep pattern of a child.

Authors: Jarrar Mu'taman , Abusalah Mai Abdel Haleem , Albaker Waleed , Al-Bsheish Mohammad , Alsyouf Adi , Al-Mugheed Khalid , Issa Marwan Rasmi , Alumran Arwa
Published: March 2023

Background:

The prevalence of type 2 diabetes mellitus (T2DM) has increased worldwide, including in Saudi Arabia.

Objective:

To systematically review the available literature and assess the pooled prevalence of T2DM in Saudi Arabia between 2000 and 2020.

Methods:

Observational studies that reported quantitative estimates of the prevalence of T2DM as their main outcome, included the general population of Saudi Arabia, and were published between 2000–2020 and in English were retrieved using three electronic databases (namely, CINAHL, Medline via PubMed, and Web of Science). Retrieved studies were screened, and relevant data were extracted. The Joanna Briggs Institute Critical Appraisal guideline was used to assess the methodological quality of included studies. A random-effects model was used to estimate the prevalence of T2DM.

Results:

Twenty-three studies were included in the systematic review, of which 19 were included in the meta-analysis (total pooled population: 258,283). The overall pooled prevalence of T2DM in Saudi Arabia was 16.4% (95% CI: 11.6–17.5). However, there was heterogeneity in the results of the studies [I2 = 99.31%, P < 0.0001] and the summary values varied from 3.18% (95% CI: 1.46–5.95) to 94.34% (95% CI: 89.53–97.38). Although the prevalence of T2DM by age varied across studies, in most studies, it was higher among the older age groups. In addition, the prevalence of diabetes widely varied across the different geographical regions of Saudi Arabia.

Conclusions:

This is the first meta-analysis that determined the pooled prevalence of T2DM in Saudi Arabia, and it revealed a high prevalence over the past two decades. However, owing to data collection inconsistencies in the identified studies, neither the modifiable (such as obesity, educational status, emotional support, etc.) nor the non-modifiable (such as gender and age) risk factors of T2DM could be determined, thereby indicating the need for a nationally collective effort in determining these factors.

Authors:   Korea Institute of Design Research Society, Wang Dong , Zou Kang
Published: March 2023

Due to the influence of COVID-19, the global economy is still dependent on the digital economy and digital technology, and the rapid growth of digital marketing plays a key role in the marketing track. Therefore, this study studied the relationship between consumers' empathy, advertising favorability, and purchase intention for digital advertisements. The survey period is 10 days from December 7 to December 17, 2022. Reliability analysis, exploratory factor analysis, relationship analysis, and regression analysis were conducted using SPSS27.0. The analysis results are as follows. First, functionality was found to have the greatest influence on the emotional design of digital advertisements. At the same time, it was found that digital media advertisements were the least intended for final purchase by consumers. Second, it was found that the emotional design elements (visual elements, auditory elements, and functional elements) of digital advertisements had a positive effect on empathy and advertisement likeability. At the same time, visual elements in the emotional design of digital advertisements seem to have affected consumer empathy and advertising favorability. Third, empathy and advertising favorability were found to have a positive effect on consumers' purchase intention. At the same time, the influence factor of empathy was found to be greater than the influence factor of advertising favorability. Therefore, it is judged that empathy between consumers and digital media advertisements is more helpful to consumers' product awareness and leads to final purchase. According to the results of this study, the following conclusions can be drawn. The perceptual design of digital advertisements should be delivered through three aspects: vision, hearing, and function, and among them, the perceptual design of digital advertisements should pay attention to the positive effects of the visual impact of advertisements. Digital advertising should find resonance with consumers and strive to achieve the purpose of promoting brands and promoting consumption by inducing emotional resonance of consumers through advertisements.

Authors:   Korea Institute of Design Research Society, Kim Byung Taek
Published: March 2023

Due to the COVID-19 pandemic, an untact environment has emerged, and fintech services have become a new paradigm. Users highly evaluate the advantages of convenience, immediacy, and cost savings in non-face-to-face business processes and actively utilize these services. As a result, various user needs are quickly coming in, and the business model of fintech services is expanding from revenue-generating activities such as deposits and loans to various tasks such as easy remittances, easy payments, asset management services, and advertising and marketing utilization. Fintech services need to use big data to provide personalized financial product information to individual users, so research on utilization based on user experience and data visualization is lacking. To solve this problem, it is important to provide insights to users through data visualization and improve overall satisfaction. Therefore, it is important to identify the elements of data visualization that affect user satisfaction with fintech services, and research results show that visual hierarchy, personalized curation, and innovative elements have a positive impact on overall satisfaction and continuous usage intention. These results can help improve the user experience of fintech services and can be applied in related fields of design research.
A study on Gorpcore in contemporary fashion
Authors:   Korea Institute of Design Research Society, Kim Sang Ja
Published: March 2023

Lifestyles have changed significantly since Corona 19, and the boundary between everyday clothes and outdoor wear has collapsed, especially among the MZ generation, who are most sensitive to trends. Practical fashion that combines the keywords of smart, sustainable, and new normal in the recession is positioned as the world's best outdoor brand, sports brand, and global fashion brand in line with the Gorpcore trend. The extensive scalability and impact of the Gorpcore style is increasing every day. However, the study of the Gorpcore style lacks precise criteria for it, and is a scarce reality due to its short history. With the increasing interest of people all over the world and the recognition of the importance of the Gorpcore style in the fashion field, research has become an urgent phenomenon. I would like to analyze and consider the Gorpcore style that has appeared in modern fashion, where there is no previous research on the Gorpcore and the standards are ambiguous, and to use it as efficient information for future research not only the exact standards but also fashion. Not only that, it is significant in that it is also used in the development of fashion designs. In addition, we expect that fashion trends that pursue practicality and functionality like the Gorpcore style and that reflect lifestyles centered on individual satisfaction will have an impact on future high fashion and fashion trends in various fields.

Arterial dissection is an uncommon complication of reversible cerebral vasoconstriction syndrome (RCVS). We describe the case of a 35-year-old woman with a migraine history who presented with recurrent thunderclap headache and focal neurological signs, including right hemiataxia. She had been diagnosed with COVID-19 disease two weeks earlier. Neuroimaging revealed multifocal stenosis of the posterior circulation arteries and dissection of the right superior cerebellar artery. She improved significantly throughout her one-week hospitalization and maintained only mild ataxia. The interplay between COVID-19 disease, RCVS, and arterial dissection requires further investigation.

Published: March 2023

The clinical presentation of multiple sclerosis (MS) is variable and can pose a diagnostic challenge. A case of unilateral perioral myokymia as the revealing feature of MS is reported. We present the case of a 43-year-old male, observed in our outpatient clinic with a two-week history of continuous involuntary wavelike movement across the left side of his face. Neurological examination revealed left-sided facial myokymia with perioral involvement and hemifacial spasm. Brain magnetic resonance imaging (MRI) showed multiple white matter hyperintensities on T2/FLAIR, suggestive of demyelination, involving periventricular, juxta-cortical regions, and the corpus callosum.
Cerebrospinal fluid (CSF) analysis showed CSF-specific oligoclonal bands. The diagnosis of relapsing-remitting multiple sclerosis was made according to the McDonald Criteria from 2017. This case illustrates an unusual presentation of MS and highlights the importance of awareness of possible MS in young adults with facial myokymia, more so when continuous and with perioral involvement.

The study of Homeless people is challenging, and describing Black Homelessness is especially difficult because of spotty record keeping[1]. The story of homeless Afro-Americans is often absent from the usual textbook study of homeless people. Homelessness is incompatibly experienced among historically marginalized groups in the united states, but for Black Americans, the distinction is especially stark[1]. Homeless condition is often occurred to the condition of poverty, less number of house, and less number of beds in the room. In most homes, there are fewer than three bedrooms and the income of each family is less, most of the rooms are already occupied. Some people in the Afro-American community are living their lives as renters what are the rent cost including the utilities like electricity, gas, water, etc is also very high. The communication system of the caucasian population is bad also, there is no phone in the family. The main reason for homelessness is that a huge number of people are immigrating within the last 5 years. The economic condition of Afro-Americans is at the poverty level, with few services, and often very poor educational opportunities. Here the data was analyzed using Multiple Regression Analysis (MRA). The proposed model is tested on the “Communities and Crime Data Set” from the UCI Machine Learning Repository: which is available at https://archive.ics.uci.edu/ml/datasets/communities+and+crime. Through this research, approximately 99.49 percent of the data was predicted correctly.

Zeolites are alumo-silicate minerals, commonly used industry, medicine and agriculture. Their application in agriculture is based on the fact that they can increase crop yield and promote nutrient use efficiency. In order to determine is zeolite (clinoptilolite) safe for use in agriculture, regarding its elemental analysis, sequential extraction followed by Inductively coupled plasma - optical emission spectrometry analysis is performed. Sequential extraction perrmited insight into elemental composition of clinoptilolite, through various extraction phases – exchagable, carbonate bounded, metals bound to Fe and Mn oxides, metals bound to organic matter and residual phase. The most abundant elements in first phase are Ca, K, Mg and Na (with a concentration greater than 100 ppm). Similar observation wa made for second phase of sequential extraction, but in this phase high content of Mn (232.6±0.7 ppm) was also noticed. In those two phases, that represents cations available to plants, no toxic elements exceeded permissible values prescribed by Serbian law. However, he content of Be (1.822±0.002 ppm) in sample obtained from third phase exceeds the concentration limit prescribed by Serbian law, which might be potentially dangerous, since Be could be adopted by plant and transferred to human through food chain. Concentration of toxic Cd was twice as higher compared to law limitations in residual phase. Bearing in mind obtained results, clinoptilolite analyzed in this study could be used in agriculture, but with continuous soil properties monitoring, since toxic elements could be mobile under various reducing and pH conditions.

A set of “host” compounds, highly suluble in water, were prepared by the reaction of β-cyclodextrin with propylene oxide in NaOH solution. The reactant ratio was varied in order to examine the difference in the substitution degree of the obtained derivatives. The structure was determined by the 1H-NMR spectra. The average degree of substitution was determined by integration of the corresponding NMR signals of the methyl group, which is part of the hydroxypropyl group and the signal from the proton attached to anomeric carbon of the β-cyclodextrin. The solubility of four different pesticides, very poorly soluble in water, was measured in water and in aqueous solution of the hydroxypropyl substituted cycloheptaamylose by ultraviolet spectrophotometry. Obtained results showed that the aqueous solution of hydroxypropyl-β- cyclodextrin was powerful solubilizer of investigated pesticides due to formation of stable inclusion complexes.
Determination of Self-absorption Correction Factors of Some Algae Samples: An Experimental study
Authors: ÖZAYDIN ÖZKARA Reyhan , EKE Canel
Published: March 2023

The purpose of this study to examine experimentally self-absorption correction factors (SACFs) of some algae samples using gamma-ray spectrometry. Various algae samples were collected from Boğaçay in Antalya, Turkey. Collected algae samples were dried, and masses of the samples were calculated. Then densities of the samples were calculated. Each of algaes was counted with and without point sources which are 22Na, 60Co, 133Ba, and 137Cs about 1000 seconds using high purity germanium detector. The SACFs of algae samples were calculated between 80 keV and 1332 keV gamma-ray energies. As a result, SACFs of studied algae samples generally reduce as gamma-ray energy enhances. SACFs of some algae samples are nearly steady because of the densities and elemental contents of the studied algaes.
Rapid Suppression of Superconductivity in Co3O4 nanoparticles-added Bi-2212 ceramics
Authors: GÜRSUL Mehmet
Published: March 2023

Bu çalışma, sırasıyla x = 0, 0.5, 1 ve 2 için %x ağırlıkça Co3O4 nano parçacıklarıyla eklenmiş Bi-2212 seramiğindeki kristal kalitesi, faz bileşimleri, süperiletken özellikler ve çivileme kuvvetindeki dikkate değer değişimlerle ilgilidir. XRD analizi, Co3O4-içeriği XRD piklerinde genişlemeye, kristal kalitesinin düşmesine ve Bi-2212 miktarının azalmasına yol açtığı sonucuna varır. SEM'den Co3O4 ilavesiyle çubuksu yapıdan plakamsı yapıya doğru bir evrilme olduğu görülmektedir. Kritik geçiş sıcaklığı (Tc), M-T ölçümlerinden saf örnekte 82 K olarak bulunmuş ve 0.5% Co örneğinde 65 K’ye 1% Co örneğinde 42 K’ye kademeli olarak düştükten sonra süperiletkenlik 2% Co örneğinde kaybolmuştur. M-H ölçümlerinden, histerezis eğrilerinin Co3O4 eklenmesi ve sıcaklıkla birlikte daraldığı görülmektedir. Buna bağlı olarak, kritik akım yoğunlukları (Jc) ve çivileme kuvvetleri (Fp), Co3O4 içeriğindeki artışın neden olduğu süper iletken tanecikler arasındaki bağlantıdaki bozulmalar nedeniyle azalmıştır.

Обучение студентов композиции на основе анализа работ художников в организациях профессионального образования
Authors: Колдина Маргарита Игоревна , Любченко Дарья Эдуардовна , Нагорная Юлия Денисовна
Published: March 2023

Художественное образование интегрировано в двух пространствах – образовательном и худо-жественно-творческом: важно не только знать теорию, но и уметь правильно применять полу-ченные знания на практике. Искусство само по себе является творческим отражением действи-тельности, воспроизведением реальных объектов в субъективных, художественных образах, поэтому для студентов необходимо выработать собственные взгляды и оценочные суждения. Создание авторской композиции на основе анализа картин художников позволяет проанализи-ровать пути воздействия на зрителя, самостоятельно систематизировать полученные знания, а также эффективно воплотить их в собственной работе, сохранив индивидуальность и неповто-римость авторской задумки.
