Published: June 2022

SUMMARY

Objectives
This study collected and analyzed clinical data regarding the repair of dental restorations in patients treated in the clinics of a dental school over 10 years.

Methods and Materials
Data related to repair procedures for permanent tooth restorations were extracted from the digital dental records system and filtered according to year (January 1, 2008, to December 31, 2017), age (&lt;30, 30–60, &gt;60), tooth group, and dental surfaces. Data were analyzed with descriptive statistics in terms of the absolute and relative frequency, and chi-square tests (95% confidence) were used to compare the frequency of repairs between years, age, tooth, and dental surfaces.

Results
A total of 48,915 dental records were accessed by searching for general restorative procedures, of which 1,408 were repairs of dental restorations on permanent teeth. The number of repairs per year increased over the period assessed, and there was a significant increase in the years 2016 and 2017. Individuals aged between 30 and 60 years received the largest number of repairs, with significantly more repairs than the other groups. Regarding the tooth group and surface, the canines and the incisal and lingual surfaces received the least number of repairs.

Conclusions
The number of repairs increased over the study period. When comparing frequencies between groups, those belonging to the 30- to 60-years of age group received more repairs; the least repaired surfaces were the lingual and the incisal.

Published: June 2022

SUMMARY

Objective
To compare the efficacy, color stability, and tooth sensitivity (TS) of combined bleaching, using a modified protocol with at-home bleaching.

Methods
Eighty participants were randomized into two groups. In the combined group, a desensitizing gel was applied (10 minutes) prior to in-office bleaching (35% hydrogen peroxide (H2O2), 2×15 minute applications) and at-home bleaching (4% H2O2, 2×30 minutes for 21 days) started the next day. In the at-home group, only the at-home bleaching was performed. Color was recorded at the beginning and postbleaching with two scales (VITA Classical and Bleachedguide) and Easyshade spectrophotometer. The TS was recorded daily with a 0–10 visual analogue scale (VAS) and five-point numeric rating scale (NRS).

Results
A 40% lower risk (RR=1.4; 95% CI 1.1–1.9) was observed in the at-home group. Higher color change and intensity of TS [mean difference 2.3 (95% CI 1.3–3.3) in the VAS] was observed in the first week for the combined group. After the end of the protocol, a bleaching degree was detected for both groups, with no significant difference between both groups (p&gt;0.05).

Conclusion
The combined group produced a slightly higher degree of color change than at-home bleaching but with a higher risk and intensity of TS.

La utilización de agregados reciclados provenientes de residuos de construcción y demolición (RCD) en nuevas obras civiles se considera el camino hacia la sostenibilidad. Esta investigación presenta la posibilidad del uso de agregado grueso reciclado (AGR) y agregado grueso tratado (AGT) de concreto en la elaboración de concretos autocompactantes (CAC). Para este propósito, dos métodos de tratamiento se realizaron a los AGR, uno de los tratamientos fue mediante desgaste mecánico en un molino de bolas y el otro fue mediante la inmersión en una solución acida (H2SO4) combinado con el desgaste mecánico. Para investigar el efecto de los AGR tratados sobre las propiedades mecánicas de los CACs, diferentes niveles de reemplazo (0%, 20% 40% y 100% en volumen) de agregado grueso natural (AGN) por AGR y AGT se realizaron. En estado fresco se evaluó capacidad de flujo, capacidad de paso y capacidad de llenado mediante el flujo de asentamiento con cono de Abrams, embudo en V y caja en L; y en estado endurecido se realizaron pruebas de resistencia a la compresión, tracción indirecta y flexión a los CACs. Los resultados muestran que los CAC con AGR presentaron una disminución en el desempeño de las propiedades en estado fresco y endurecido debido a la presencia del mortero adherido en este tipo de agregados, sin embargo, su trabajabilidad se encontró dentro de los parámetros establecidos por la EFNARC. Las propiedades mecánicas de los CAC con AGT presentaron un mejor desempeño en comparación a los CAC con AGR, debido al retiro del motero adherido mejorando la resistencia a la compresión todas las mezclas. Además, los CAC con AGT mostraron mejoras en las propiedades de permeabilidad presentando una reducción de porosidad de hasta un 6,06%.

Published: June 2022

Abstract
In the context of coronavirus (COVID-19) pandemic, large-scale events have been forced to stop as well as movement of people between cities. At Daxi in Taoyuan, Taiwan, there is an event that lasts for over a century, Puji Temple Annual Celebration of Saintly Emperor Guan’s Birthday, held every summer on June 24 of the lunar calendar. It is not only registered as Taoyuan City’s intangible cultural heritage but also considered as the second Chinese New Year for local people. In order to express gratitude to Saintly Emperor Guan for his blessing, the local groups ‘She-Tou’, residents, shopkeepers and volunteers make a great effort on the preparations before the celebration. Local people who at the time do not live in Daxi because they are studying, working or after marriage are living in other cities would also come back to the town on this day. This traditional and cultural event bred from belief has become a mechanism of community cohesion and has shaped Daxi’s unique sense of place. Unfortunately, the traditional pilgrimage of the celebration in 2021 has been paused due to the pandemic situation. However, thanks to the long-term collaboration and participation of the local museum, the ritual of faith can continue in a new way. This article takes the DaxiDaxi “Lord Guan Online” website and its Facebook page as an example. By analysing how the Daxi Wood Art Ecomuseum interprets the traditional celebration and its culture in a digital way, we try to explore the possibility of digital tools as a powerful medium for connecting people and people and place during the pandemic period.
Modeling consumer behavior – Psychological paradigm
Authors: Anghel Mihai Alin 
Published: June 2022

Abstract
Modeling consumer behavior can be explained in the context of specific paradigms: sociological, psychological, cultural, neurocognitive, anthropological, and economic. With the discoveries in the field of neuroscience, the perspective of over-explaining consumer behavior is heading more toward cognitive neuroscience. The research in neurophysiology has succeeded in explaining the interpsychic processes and in the creation of multiple theories which are trying to determine the cause of human organism reaction to different external stimuli. The current scientifical challenges can be found especially around neuropsychology which is attempting to explain how the human brain works and which are the sections that influence the behavior. The research from neurobiology mentions the fact that at the core of buying purchases is a neurophysiological layer.

Abstract
Severe pain is a major problem in the early postoperative period after open major upper gastrointestinal surgery. This study aimed to assess the efficiency of rectus sheath block with catheters placed through open access into the retromuscular space in providing effective pain relief. A prospective study was done at Rīga East University Hospital, Latvia. Thirty-nine patients with open gastrectomy were allocated into two groups: 21 patients in the block group and 18 patients in the control group. In the block group, at the end of the operation, two catheters were inserted into the retromuscular plane under the m. rectus abdominis through the open access (using a specially invented technique). After surgery, patients in the block group received continuous 0.125% (10–12 mg/h) bupivacaine infusion through rectus sheath catheters for 72 hours. Patients in the control group received standard postoperative analgaesia. The results showed that postoperative pain at rest was significantly lower in the Block group than in the control group at 48-hour and 72-hour intervals after surgery. Pain on movement in the block group was significantly lower than that in the control group at all postoperative times: at 24, 48, and 72 hours. The median fentanyl requirement range in the postoperative period was significantly lower in the block group (0.5 (0–1.25) mg) than in the control group (2.0 (1.0–3.25) mg (p = 0.001)). Continuous retromuscular rectus sheath infiltration of 0.125% bupivacaine through a rectus sheath catheter after open gastrectomy provides effective postoperative analgaesia in the early postoperative period and significantly reduces opioid consumption.

Published: June 2022

Abstract
Inherited peripheral neuropathies (IPN) are a clinically and genetically heterogeneous group of disorders. The most common IPN is Charcot-Marie-Tooth (CMT) disease. Here we describe IPN clinical variability and diagnostic characteristics in the Latvian population. A total of 101 patients were enrolled in the study. Genetic testing consisted of PMP22 copy number analysis and whole-exome sequencing (WES). Clinical assessment comprised CMT Neuropathy Score version 2 (CMTNSv2), CMT Examination Score, pain, anxiety and memory/cognitive ability testing. The diagnostic yields for PMP22 copy number detection and WES were 45.8% and 77.8%, respectively. Disease severity assessment indicated high clinical heterogeneity, with CMTNSv2 scores ranging between 0 and 33. More than one-third of patients reported pain, and it was found to be significantly more common in patients with at least a mild anxiety level. From the initial development of symptoms, on average, it took more than 13 years for a diagnosis of IPN to be confirmed. This study updates the IPN genetic and clinical profile of the Latvian population and demonstrates the presence of a high level of heterogeneity. The time to diagnosis for IPN patients needs to be improved by employing multiplex ligation-dependent probe amplification initially followed by WES.

Published: June 2022

Abstract
We analysed the age- and sex-specific incidence, disease-stage distribution, treatment modalities, and survival of patients with hepatocellular carcinoma (HCC) in Latvia from 1997 to 2017. Retrospective data from the Cancer Registry of Latvia identified 692 men and 427 women aged >19 years who were diagnosed with HCC, confirmed by autopsy, morphological, radiological, or clinical examinations. The total incidence of HCC increased from 2.63 to 3.75 cases per 100 000 person-years in 1997–2007 and 2008–2017, respectively. It was higher in men and increased with age. Two-thirds (65.9%) of patients were diagnosed with stage IV HCC. Overall, 935 patients died during follow-up. The survival rate was low: 32.5% and 22.2% of patients survived for 6 months and 1 year after diagnosis, respectively. Male sex, older age, and advanced stage at diagnosis were associated with poor prognosis. The proportion of radically treated patients was higher, and survival was better, in the period 2008–2017. Our epidemiological analysis of HCC over 20 years shows that the overall incidence of HCC has been increasing in Latvia since 1997; however, it is similar to that of other European countries. Advanced stage at diagnosis results in a low proportion of radically treated patients and poor overall survival.
Development and Physiological Performance of Hydroponically-Grown Ornamental Indoor Plants in Relation to their Potential Use in Botanical Biofilters: Effect of Mineral Nutrient Availability
Authors: Ievinsh Gederts , Andersone-Ozola Una , Sieriņa Alise 
Published: June 2022

Abstract
The aim of the present study was to evaluate the effect of different levels of mineral nutrient availability on development and physiological performance of several common indoor ornamental plant species (Anthurium sp., Chlorophytum comosum, Epipremnum aureum, Plectranthus fruticosus, Spathiphyllum sp., and Tradescantia pallida) cultivated in hydroponics with potential use in active botanical biofilter systems. Plants were grown in expanded clay granules at four levels of mineral nutrient availability provided by two types of commercial mineral fertiliser. The growth stimulative effect of increased mineral nutrient availability depended on plant growth rate, with a lower effect on slower growing species. The need for nutrients increased in the order Anthurium < Spathiphyllum < Epipremnum < Chlorophytum < Tradescantia < Plectranthus. Tissue water content showed pronounced differences between various plant species as well as between plant organs. For several species, increase in mineral nutrient availability resulted in a significant increase in tissue water content. Chlorophyll fluorescence analysis showed that indoor plants can successfully adapt to low and moderate mineral fertiliser levels with balanced individual nutrient rates, without negative consequences to photochemistry of photosynthesis. Consequently, indoor plants can be cultivated at a relatively low concentration of mineral nutrients for optimum utilisation in active botanical biofilter systems.
On a Class of Lacunary Almost Newman Polynomials Modulo P and Density Theorems

Published: June 2022

Abstract
The reduction modulo p of a family of lacunary integer polynomials, associated with the dynamical zeta function ζβ
(z)of the β-shift, for β> 1 close to one, is investigated. We briefly recall how this family is correlated to the problem of Lehmer. A variety of questions is raised about their numbers of zeroes in 𝔽
p
and their factorizations, via Kronecker’s Average Value Theorem (viewed as an analog of classical Theorems of Uniform Distribution Theory). These questions are partially answered using results of Schinzel, revisited by Sawin, Shusterman and Stoll, and density theorems (Frobenius, Chebotarev, Serre, Rosen). These questions arise from the search for the existence of integer polynomials of Mahler measure > 1 less than the smallest Salem number 1.176280. Explicit connection with modular forms (or modular representations) of the numbers of zeroes of these polynomials in 𝔽
p
is obtained in a few cases. In general it is expected since it must exist according to the Langlands program.

Ogan Komering Ulu Regency is a district that has great potential for agricultural businesses, especially rice farming. For rice production in South Sumatra Province, Ogan Komering Ulu district in 2020 occupies the 12th position out of 17 districts/cities, with a total production of 16,807.12 tons of dry milled grain (kg). Ogan Komering Ulu Regency has 13 sub-districts which are rice-producing areas. The Ogan Komering Ulu Regency Government continues to strive to increase the production and productivity of rice commodities in its area. The increase in rice production in Ogan Komering Ulu Regency is not only to meet regional needs but is expected to contribute to increasing national rice production. In 2020 the highest total rice harvested area in Ogan Komering Ulu Regency is in Ulu Ogan District, which is 1,690 ha, with dry milled grain production (kg) of 9,464 tons. So that it can be said, Ulu Ogan District is a food barn for Ogan Komering Ulu Regency. Rice production is the amount of rice obtained at the time of post-harvest. Yield will be affected by land area, fertilizer, and labor. This rise and fall in production results can be caused by several factors that are not precise enough so the production of lowland rice is not optimal. Therefore, there is a need for further analysis related to the factors that influence the production of lowland rice farming in Ulu Ogan District, Ogan Komering Ulu Regency. This study aimed to analyze the factors that influence the production of lowland rice in Ulu Ogan District, Ogan Komering Ulu Regency. This research was conducted in Ulu Ogan District, Ogan Komering Ulu Regency. Sampling in this study was done by a simple random sampling method with 65 farmers as respondents. The variables measured in this study were land area, urea fertilizer, labor, number of seeds, and pesticides. The production model used is the Cobb-Douglas model regression analysis. To see the effect of each production factor on the resulting production using multiple linear regression analysis simultaneously the variables of land area, urea fertilizer, labor, number of seeds, and pesticides affect rice production in Ulu Ogan District, Ogan Komering Ulu Regency. Individually the variables of land area and number of seeds have a significant effect on rice production factors.

В статье анализируется ресурсный потенциал территории Азиатской России, который наряду с минеральным сырьем и топливом включает биоресурсы, леса как источник рекреации и декарбонизации и само географиче- ское пространство. Обсуждаются исторически сложившиеся проблемы развития регионов, имеющие как объективную обусловленность, так и субъективную составляющую, вызванную порочностью подходов к управлению территорией. Слабая освоенность и связность пространства, суровый климат ведут к допол- нительным издержкам развития Азиатской России, в то же время для ускорения экономического роста в стране требуется быстрое развитие ее экономики. Предложен подход, основанный на концепции «большого инвестиционного импульса», который должен позволить усилить рост экономики территории. Рассмотрен ряд проектов черной металлургии, которые могут стать полигоном для реализации указанной концепции в Сибири и на Дальнем Востоке, а также Комплексный инвестиционный проект «Енисейская Сибирь», как реальная основа создания инновационных промышленных кластеров, обеспечивающих связанность и конкурентные отношения между участниками кооперационных проектов.
