EFFECTIVENESS, OUTCOME, AND SAFETY OF VITAMIN D SUPPLEMENTATION IN PATIENTS WITH PSORIASIS: A COMPREHENSIVE SYSTEMATIC REVIEW
Authors: Yulianto Ronald , Aristika Gunawan Ellen
Published: April 2024

Background:  Insights into psoriasis as a systemic ailment have spurred the investigation of novel therapies due to dissatisfaction with current treatments and significant quality of life impairment. Vitamin D3 deficiency is implicated in psoriasis pathophysiology, with studies highlighting its impact on keratinocyte regulation and autoimmune disease resistance. This review critically evaluates evidence on high-dose oral vitamin D3 supplementation for psoriasis management, aiming to assess its effectiveness, treatment outcomes, and safety profile to inform clinician.    
Methods: This systematic review focused on full-text English literature published between 2017 and 2024 using the PRISMA 2020 guidelines. Editorials and review pieces published in the same journal as the submission without a DOI were not accepted. The literature was compiled using PubMed, ScienceDirect, and SagePub, among other online venues.
Result: Our research team initially collected numerous publications from credible sources such as Science Direct, PubMed, and JAMA Dermatology. Employing a meticulous three-tier screening approach, we identified only five papers that were directly pertinent to our ongoing systematic assessment. Subsequently, we conducted a comprehensive examination of the entire text and further selected articles; case control study, double-blind, randomized, placebo-controlled study, randomized controlled trial, a bidirectional two-sample mendelian randomization analysis, and observational cross-sectional study.
Conclusion:  In conclusion, maintaining serum vitamin D levels above 30 ng/ml may benefit severe psoriasis, while oral vitamin D2 supplementation showed promise in mild cases. Larger trials are needed for severe psoriasis, and future research should explore higher doses. Additionally, a study found no support for monthly vitamin D3 supplementation in older mild psoriasis patients. We confirmed the causal link between vitamin D levels and psoriasis, identified associations with increased risk, and explored effects on atopic dermatitis. While no significant difference was found in serum vitamin D levels between psoriasis patients and controls, lower levels in psoriasis suggest various influences.

Authors: Zhu Ziyu , Liu Jiazhen , Ji Xionghui , Huang Hongkun , Fang Ping
Published: April 2024

Accurate and comprehensive estimation of agricultural non-point source pollution (ANPSP) is of vital importance in watershed pollution control, while data inaccessibility and complexity of process-based models may be main restrictions in practice. An estimation methodology framework for ANPSP was established based on improved export coefficient model (IECM) in this research. A series of updated, regional coefficients were collected and/or calculated with multiple pollution sources considered (i.e., animal husbandry, farming and forestry, fishery, and rural domestic sewage) to provide a comprehensive estimation of TN and TP pollution loads in Taihu Lake Basin. According to this model, pollution loads of TN and TP in Taihu Lake Basin were 65791.28 and 11400.38 t in 2016, respectively. Animal husbandry was main source of ANPSP, accounting for 31.05% and 66.70% for TN and TP, respectively, which requires more efficient and clean agricultural production modes and strict pollution control measures. IECM-based estimation framework may provide a reference for ANPSP management practice in large scale watershed.

Published: April 2024

The human eyes can perceive light even when napping during the day. In order to further investigate the effects of constant light exposure during napping on nap quality and subjective alertness, seven lighting conditions were designed in this paper, L0 (darkness), L1 (60 lx, 2800 k), L2 (300 lx, 2800 k), L3 (600 lx, 2800 k), L4 (60 lx, 5800 k), L5 (300 lx, 5800 k), L6 (600 lx, 5800 k). 12 participants were invited to perform a 30-minute light intervention nap experiment. Participants' Pittsburgh Sleep Quality Index (PSQI), Electroencephalographic (EEG), Karolinska Sleepiness Scale (KSS), skin temperature, and heart rate data were recorded. The results show that at L2 afternoon nap, θ band share is higher than other lighting conditions. At L6 afternoon nap, the δ band share was the lowest. High illuminance and low CCT significantly affected immediate subjective alertness during nap wakefulness, but reduced afternoon alertness was not related to light during nap. Although post-nap vigilance was lowest in L0 darkness, it rose rapidly to a maximum within 30 min of waking. From 0-25 min of napping, heart rate decreased significantly at L1  vs. L4, and skin temperature increased significantly at L2 vs. L5. None of the seven lighting conditions (L0-L6) inhibited participants' napping to a greater extent, and high illuminance and high colour temperature did not significantly increase the level of nap arousal (25-30 min).

Published: April 2024

The accurate prediction of blasting vibration plays an important role in the evaluation of blasting negative effects and the optimization of blasting design. On the premise of clarifying the influencing factors of blasting vibration propagation, combined with dimensional analysis, based on the traditional Sadovsky formula, through the introduction of horizontal distance and elevation difference factor, the attenuation law of blasting vibration under mountainous terrain conditions is studied, and the blasting vibration prediction formula reflecting mountainous terrain conditions is established. Combined with the measured vibration data of underground powerhouse excavation of Xiamen pumped storage power station in Fujian Province, when the elevation between the measuring point and the explosion source changes greatly, the prediction errors of horizontal and vertical vibration by using the traditional Sadovsky formula are large, about16 ~ 25%respectively. The prediction errors of vibration prediction formula based on dimensional analysis are small, about 8 ~ 12%. The results show that the particle vibration peak formula based on dimensional analysis can be better applied to the prediction of blasting vibration under complex terrain.
The Determination of Effective Modes of Wind-Bridge Coupling System Based on Stabilization Clustering Method
Authors: Zhang Xingbo
Published: April 2024

Modal identification is the core content of the full-bridge aeroelastic model wind tunnel test. Modal consistency is the most direct and effective basis to ensure that the model and the real bridge meet the similarity criteria. Accurate, simple and fast identification of modal parameters has very important practical significance for the evaluation and correction of aeroelastic models. In this paper, the eigensystem realization algorithm (ERA) and stochastic subspace identification (SSI) is improved, and the automatic identification theory of effective modes of bridge aeroelastic model based on stable clustering method is proposed. The stable diagram eliminates the unstable modes by comparing the results of different system orders, and the pedigree clustering further polarizes the stable modes to obtain multi-order and high-precision system modes. Numerical simulation examples and wind tunnel engineering examples show that the method has high accuracy and good adaptability, and can solve the problem of unstable damping identification results to a certain extent. In the wind tunnel test, the stable clustering method is one of the effective methods to identify the modal of the bridge aeroelastic model excited by the wind environment.

Analysis of Regional Characteristics of Trademark Design in Modern Zhejiang Province
Authors: Guo Yiqi , Wang Zhehao
Published: April 2024

Through the collection of information collation and investigation, the author summed up the characteristics of trademark design in modern Zhejiang as "ancient style and Folk charm, Water with new trendy." The "ancient style" is the inheritance of Zhejiang cultural tradition, and the "Folk charm" is the characteristics of "living" and "localization" in trademark design. The development of culture and technology has its "stickiness". Compared with Shanghai, which opened to the outside world in 1843, the "imagined picture" in the modern Calendar card is not filled with the trademark advertisements designed by Zhejiang. Most of the trademark design forms can see the natural feeling of modern Zhejiang trademarks for the traditional evolution, whether the subject matter, trademark structure, the conversion of Zhejiang art, or the space construction of folk life. After the Opium War, Zhejiang was opened as a port in Ningbo, Wenzhou and Hangzhou. The exogenous variables in the western world influenced Zhejiang in modern times.

Published: April 2024

Mot bakgrund av en breddad och allt mer komplex hotbild mot Sverige och en ambition att stärka den svenska totalförsvarsförmågan har regeringen och Regeringskansliet på senare år skjutit till nya medel och försvarsanslag till det militära och civila försvaret, inklusive den militära Säkerhetstjänsten. De har även tagit fram ett antal nya lagar och regler som på olika sätt syftar till att vägleda säkerhetstjänstens verksamhet och stärka landets motståndskraft mot olika säkerhetshot inom ramen för totalförsvaret. Denna antologi har till uppgift att utifrån olika perspektiv analysera hur moderna hotbilder, ny teknik, lagstiftning, natomedlemskap och krav på samverkan med andra myndigheter och företag kommer påverka den militära säkerhetstjänstens och säkerhetsunderrättelsetjänstens verksamhet i framtiden. Antologin är skriven av några av Sveriges ledande experter på området i syfte att beskriva de utmaningar som den militära säkerhetstjänsten och säkerhetsunderrättelsetjänsten står inför samtidigt som totalförsvaret och krisberedskapen i Sverige återuppbyggs. Några av de frågor som ställs i antologin är hur och i vilken utsträckning det försämrade säkerhetsläget i vårt närområde, ny säkerhetsskyddslagstiftning, ambitionen att stärka det svenska totalförsvaret och Sveriges medlemskap i Nato kommer leda till att säkerhetstjänstens arbetsuppgifter förändras i framtiden? Slutsatserna från denna antologi är säkerhetstjänsten och säkerhetsunderrättelsetjänsterna i Sverige står inför ett paradigmskifte där det kommer vara nödvändigt att modernisera organisationen och implementera ny teknik för att anpassa sig till den digitala eran. Även vikten av intensifierad internationell samverkan kommer spela stor roll för säkerhetstjänstens möjligheter att bedriva ett effektivt arbete på nationell nivå i framtiden.

Todas las organizaciones, ya sean privadas o públicas, gastan recursos en el proceso de reclutamiento y de selección de sus trabajadores, sin embargo, no consideran los mismos criterios. En este artículo se hace un análisis comparativo de estos procesos, para hacer diferenciaciones entre el sector público y el privado. El estudio es de campo, con enfoque cuantitativo y de alcance correlacional, mediante el coeficiente de Pearson, considerando como muestra a cuatro empresas públicas y cuatro privadas, seleccionadas de manera no probabilística a juicio de los autores. La principal conclusión es que todos los criterios analizados, son mejor valorados en el sector privado que en el público, a excepción del proceso en general, valorado en ambos sectores como Malo.  Acorde al análisis general de todas las preguntas se determina una correlación de 0,144, esto quiere decir que no existe una asociación significativa entre las percepciones de los criterios analizados entre el Sector Público y el Sector Privado. Mientras que, en las correlaciones por cada uno de los criterios, existe asociación positiva, es decir afinidad entre empresas públicas y privadas, en criterios como la preparación de los encargados, el desempeño de los trabajadores y en la valoración del proceso en general.

Para el funcionamiento de estas aplicaciones utilizando un servidor VPS con la empresa DDos, donde se trabaja con limitantes que suponen el hecho de tener la recurrencia de usuarios en busca de servicios institucionales. Con el pasar de los años y el incremento de los procesos institucionales las aplicaciones crecen y necesitan de un espacio cada vez más amplio que permita almacenar de manera correcta, por tanto, se realizó una serie de configuraciones que ha permitido el funcionamiento adecuado de las aplicaciones. Debido a la situación económica de la institución es difícil mantener un servicio pagado del VPS por lo que mediante gestiones con la SENESCYT se consiguió la dotación de 3 servidores VPS para el alojamiento de las aplicaciones que se distribuyen: VPS 1: Sistema académico Cerberus, Aula Virtual, Biblioteca, Bolsa de empleo; VPS 2: Micrositio y revista científica de investigación. VPS 3: Practicas de estudiantes. Con los VPS recibidos se procede a la instalación y configuración de los mismos mediante el uso de varias herramientas de software libre como sistema operativo Alma Linux 8, CyberPanel como software de administración gráfica, OpenLiteSpeed como servidor web, PHP como lenguaje de programación, MariaDB como gestor de base de datos, Sophos Connect para conexión privada, PuTTY como gestor de conexiones remotas; finalmente se procedió a la migración de las aplicaciones institucionales al nuevo entorno.
