Background: Massive rotator cuff tears (RCTs) are complicated by muscle atrophy, fibrosis, and intramuscular fatty degeneration, which are associated with postoperative tendon-to-bone healing failure and poor clinical outcomes. We evaluated muscle and enthesis changes in large tears with or without suprascapular nerve (SN) injury in a rat model. Methods: Sixty-two adult Sprague-Dawley rats were divided into SN injury (+) and SN injury (–) groups (n=31 each), comprising tendon (supraspinatus [SSP]/infraspinatus [ISP]) and nerve resection and tendon resection only cases, respectively. Muscle weight measurement, histological evaluation, and biomechanical testing were performed 4, 8, and 12 weeks postoperatively. Ultrastructural analysis with block face imaging was performed 8 weeks postoperatively. Results: SSP/ISP muscles in the SN injury (+) group appeared atrophic, with increased fatty tissue and decreased muscle weight, compared to those in the control and SN injury (–) groups. Immunoreactivity was only positive in the SN injury (+) group. Myofibril arrangement irregularity and mitochondrial swelling severity, along with number of fatty cells, were higher in the SN injury (+) group than in the SN injury (–) group. The bone-tendon junction enthesis was firm in the SN injury (–) group; this was atrophic and thinner in the SN injury (+) group, with decreased cell density and immature fibrocartilage. Mechanically, the tendon–bone insertion was significantly weaker in the SN injury (+) group than in the control and SN injury (+) groups. Conclusions: In clinical settings, SN injury may cause severe fatty changes and inhibition of postoperative tendon healing in large RCTs. Level of evidence: Basic research, controlled laboratory study

The Department of Population and Civil Registration of Muaro Jambi Regency is the executor of government affairs in the field of population administration, in general for office administration purposes, such as archiving documentation and correspondence management. In general, the work process in local government agencies is inseparable from various problems, such as work management that is not good and neat, or other information management processes that are deemed inaccurate. The results of the study show that the management of incoming and outgoing letter archival data still uses a manual system, namely recording in an agenda book and then placing the letters in a special mail archive cupboard without any backup data. The management of letter archives at the Population and Civil Registration Office of the Muaro Jambi Regency is carried out by the general and personnel sub-divisions. The facilities available at this time are an agenda book to record incoming and outgoing mail data, then a cupboard as a means of storing archival data of incoming and outgoing letters. The solution proposed by the author is to design and build a web-based E-Office application system for archiving incoming and outgoing mail data. In developing the system the author uses the method (Waterfall) and UML design along with supporting applications for making the application developed using the java programming language, php, and the MYSQL database. The results of making this application can be used by the Muaro Jambi Regency Population and Civil Registration Service, especially as a medium for completing documents and other official letters.

Research on Museum Brand Building under the New Media Environment
Authors: Xue Yuchen
Published: May 2023

The fierce market competition makes the phenomenon of museum homogenization serious. In order to stand out, museums must put good brand building and appropriate marketing communication in an important position. This is of great significance to enhance the brand image of the museum and promote the development of the museum. The development of new media has further expanded the extension of the media environment and diversified the ways of brand building. Through the interaction and feedback of the new media platform, the experience and communication between the audience and the museum can be increased. The continuous development of cultural and creative products is an in-depth excavation of the cultural value of museums. Through the dissemination of new media, it can help to establish the unique image of the museum and further strengthen the brand relationship between the audience and the museum. Unlike traditional museums as cultural institutions that often leave a serious impression on the public, museums in the new media environment weaken the sense of cultural distance from the public and create a new image of the museum. Taking the exploration of the Palace Museum in recent years as an example, this paper introduces the attempt of the Palace Museum to actively use new media and other means to tap the characteristic cultural resources and cultural connotation, shape the influential museum brand, and develop a new museum model.

Authors: Sidabalok Supriani , Rosyetti Rosyetti , Zamaya Yelly , Misdawita Misdawita
Published: May 2023

212 Mart Pekanbaru is one of the sharia retail businesses whose presence is expected to be able to provide a comfortable modern shopping place for Muslim consumers, especially in the city of Pekanbaru. Its relatively new presence causes it     to not be able to compete and seize the existing market. Consumers themselves have several considerations in choosing a place to shop or become loyal consumers       by joining as a member at a Mart. These reasons and considerations are important to analyze as input for Mart managers in managing their retail. By using Theory of Planned Behavior (TPB) as a theoretical basis, this research uses five independent variables namely income, attitude, subjective norms, individual        control, and religiosity to see the main factors that influence consumer decisions to become members of 212 Mart. The analysis technique used in this study is logistic regression analysis with 100 consumers at 212 Mart Pekanbaru as respondents. The results showed that only the subjective norm variable had a significant effect on the Muslim consumer's decision to become a member of 212 Mart. The income, attitude, individual control, and religiosity variables have no significant effect.
Multipurpose Freshwater Coastal Reservoirs and Their Role in Mitigating Climate Change
Authors:   Department of Mechanical Engineering, Eddanapudi, Hyderabad (Telangana), India, Sasidhar Nallapaneni
Published: May 2023

A coastal reservoir (CR) is a freshwater reservoir to store river water in the sea area adjacent to the sea coast by replacing seawater. A CR is formed by constructing a long oceanic dike to impound surplus water that is flowing to the sea from a river basin. Freshwater from the CR is pumped throughout the year into a series of embankment canals to reach upland areas for meeting agricultural, industrial, municipal, etc water needs along with the required base blows and environmental flows in river basins. The embankment canals also create pumped storage hydropower (PSHP) potential to meet the energy storage requirements for harnessing variable power resources like solar, wind, etc which are economical, clean, renewable, and carbon neutral. The oceanic dike also creates a mega-scale ultra-deep sea harbor along with a coastal highway and railroad. CRs are cheaper to construct compared to land-based reservoirs wherever the cost of submerged land and immovable property acquisition and rehabilitation of the affected population is very high. They also serve multipurpose utilities such as deep-sea harbor, road transport, rail transport, land reclamation, PSHP energy storage, rejuvenation of over-exploited rivers, etc without appreciable overall environmental damage. CR projects are feasible in every continent except Antarctica as there are few mighty rivers with huge surplus water discharges to the sea and also the existence of vast desert/semi-desert areas which can be converted into productive agricultural lands or forest lands with water supplied from the CRs. Greening the desert or semi-desert lands into lush green farms or forest lands would enhance the soil carbon storage and also provide food grains and biomass. The available biomass can be used as feedstock to produce carbon-neutral biofuels to replace fossil fuels which are contributing to global warming. Few feasible CR projects are listed in the paper that can harness nearly 9,000 billion cubic meters (bcm) of water annually and contribute to achieving a carbon-neutral world. To explain the concept of the freshwater CRs and the associated embankment canals, a CR project to utilize the surplus waters of the Brahmaputra, Ganga, and Meghna rivers is considered as a case study in some detail in this paper. The project would create a 360 bcm capacity CR to harness nearly 1,200 bcm of water throughout the year regardless of monsoon vagaries for meeting various water needs in all major river basins between the Ganga and Krishna rivers.

Cuttings were collected from different provenances of Populus alba in Himachal Pradesh and Jammu & Kashmir during 1999-2000. These were raised in the nursery of Dr. Y.S. Parmar University of Horticulture and Forestry, Solan as a mother nursery stock. From them cuttings were taken in the year 2001 and they were planted in nursery for this provenance trial. Analysis of variation revealed highly significant differences among different provenances for height, basal diameter, number of leaves, leaf area, internodal length, root fresh weight, root dry weight, shoot fresh weight and shoot dry weight under nursery conditions. For the seedling traits provenance-Tirith (P17) excelled for height, basal diameter, leaf area, internodal length, root fresh weight, root dry weight, shoot fresh weight and shoot dry weight. Tabo provenance (P21) recorded minimum value for height, leaf area and internodal length whereas, Holdoo (P13) for number of leaves. Variability and genetic estimates revealed high heritability for seedling height, basal diameter, root fresh weight, and root dry weight. Heritability value was found low for number of branches. Divergence (D2) studies indicated remarkable diversity among 26 provenances of P. alba. Sikibba (P10) and Tamrot (P12) were considered most diverse populations (D2 value 57771.20). Correlation studies illustrated significant positive correlation between different traits, viz., height, basal diameter, number of leaves, internodal length, root fresh weight, root dry weight, shoot fresh weight and shoot dry weight.

Can the TGfU model affect the moral disengagement of children with social, emotional, and mental health needs in physical education?
Authors: D Dimmick
Published: May 2023

Using the teaching games for understanding model (TGfU) as an intervention strategy, this study intended to establish whether it could affect the moral disengagement (MD) levels of students / participants with special educational needs and disabilities; (SEND) by enhancing their positive behaviours in physical education (PE). The study focused on male students (n = 12) aged 13-14 years old who all had a range of different SEND conditions and they were taught within a special school setting in the UK. The intervention activity focussed on the sport of Indoor Hockey and this was taught by an experienced Teacher of PE over a period of six-weeks. The study used several qualitative approaches to collect and analyse the data. For example, the students completed two questionnaires and the teacher-researcher gathered field notes over the course of the intervention period. The data collection methods which were used to triangulate the results were an adapted qualitative ‘Physical Education Classroom Instrument’, an instrument called the ‘Moral Disengagement tool in Physical Education’ (MDPE), which was specifically designed for the use within a physical education setting and the teacher-researcher field notes. In conclusion the results from study show that by implementing MD minimisation strategies such as the TGfU model, can reduce students’ misbehaviours in PE lessons focussed on games such as Indoor Hockey and also moral disengagment minimisation strategies can help reduce the misbehaviours of students in PE with SEND.

In this paper, the occurrence of large forest fires in the management area of ŠPD “Srednjobosanska šume” in 2020 was analyzed with regard to forest types and management classes. The period of April–May 2020 was characterized as a period with a particularly high occurrence of forest fires, where the burnt area was 1,030.36 ha, and the material damage was 1,893,559.15 KM. The causes of the fires are unknown, as are the instigators. In most cases, the human factor was found to be the cause, and in three cases it was determined that the fire was caused intentionally. The danger of certain categories of forests (and forest land) from fire is different. The biggest financial damage was caused by the burning of areas under young cultures, i.e. due to damage to seedlings. The aim of the research was to assess the number, frequency and damage caused by fires, as well as the risk of certain categories of forests from fires. Such research is essential for assessing the degree of threat to forests and forest land from fire.

Published: May 2023

In this research, a maize starch-peanut shell nanocomposite film was applied to package mushroom under varying moisture, thickness, and cold temperature conditions. The film was developed by congealing 18 g starch, 0.38 g peanut nanoparticles, 16 g glycerol in 300 ml distilled water at 70oC, and its thermal, mechanical, barrier and microstructural behaviors were determined using standard methods. The film was applied to package oyster mushroom by varying the thickness (5– 10 mm) and moisture content (77.18 –91.14 %, wb) of the product, and thereafter storing it under 4– 8 oC cold temperature condition. The results revealed ~ 5% weight fraction degradation at ≤ 310 oC with endothermic peaks occurring at 250 oC and 400 oC, which corresponds to phase transition points where the film was thermally stable. The deformation pattern of the film at atomic level mimics a natural plastic material, with a heterogeneous particle size distribution across the film matrix. The permeability coefficients were 0.68× 10-10, 2.10× 10-10 and 14.0× 10-10 cm3 (STP) cm/cm2scm Hg for nitrogen, oxygen, and carbon-dioxide, gases, respectively. Also, the microbial load of the packaged product significantly decreased with an increase pH, moisture, and temperature (p< 0.05). Thus, the film can be suitable for mushroom packaging.

The present study investigated the suitability of combinations one Streptococcus thermophilus and five Lactobacillus delbrueckii subsp. bulgaricus isolates for industrial yogurt productions. The isolates were selected after a detailed pre-screening procedure based on acidification performances, production of volatile aroma compounds, texture developing properties and sensory evaluations of yogurts made from single cultures. The fermentation profiles of the combinations were investigated by monitoring the small oscillatory rheological parameters and pH reductions during fermentation. The variations in some physical, chemical and organoleptic characteristics of the yogurt samples were also monitored during cold storage at 4 ºC for 21 days. Results indicated that all the combinations reduced the milk acidity to pH 4.6 within 4-5 hour at 43 ºC. Gelation profiles of the samples were close to each other (close tan δ values) with different elastic (G') and loss (G") moduli, indicating that similar chemical bondings took place in gel formation with different levels. All the samples showed a shear-thinning non-Newtonian flow behavior. Total number of starter bacteria was higher than 6 log cfu/mL in each sample after 21 days of storage. The post-acidification rates were also limited (between 4.21-4.37 after 21 days of cold storage). Untrained sensory evaluation panel found no marginal differences between the samples regarding appearance, body and texture, and aroma and flavor of the samples. To conclude, the combinations examined in this study were found to be suitable for commercial yogurt productions.

The use of insects is a modern trend in the food industry with a positive impact on ecology and sustainability. Not only the popularity of eating whole insects is growing among consumers, but also products with an insect component are preferred more. It is also used in foods for special nutrition. Gluten-free bar made with cricket powder can represent a functional food stuff. The study shows that the addition of insects can increase the Total Polyphenol Content (24.78 mg GAE/ 100 g to 44.68 mg GAE/ 100 g) (p < 0.05). There is also an increase in antioxidant activity expressed as scavenging activity (%) for ABTS from 7.33 to 50.17, for DPPH 4.10 to 33.88 (p < 0.05). The influence of cricket powder was also recorded in the moisture content of the product, when the increased addition of insects led to a decrease in moisture content (R=0.89). Sensory evaluation showed overall acceptability for these bars. Texture, taste, appearance, aroma and overall pleasantness were compared. Although the protein bars without cricket content (Ctrl) had the highest overall pleasantness rating, it differed statistically significantly (p < 0.05) only from the sample with the highest cricket powder content (B25I).

This study investigated the use of targeted analysis to verify the geographic origin of ground paprika samples. In total, 36 samples were analyzed from all over the world (17 from Europe, 17 from Asia, one from North America, and one from Africa). Deliberately chosen methods that use equipment commonly available in control laboratories were used for the analysis. The samples were examined for total fat content, total protein content, sugar concentration, the concentration of selected elements, ASTA coloring, ash content, and pH of the extract. The results were processed using multivariate analysis, which showed that, based on these investigated parameters, it is possible to differentiate ground paprika samples from different regions. In addition to being able to separate samples originating from Asia from those originating from Europe, it was also possible to distinguish samples from Europe with protected geographical indications, such as paprika from Hungary, Spain, and Slovakia.

Published: May 2023

Vietnam is a country that produces a variety of agricultural products, including vegetables, tubers, fruits, and processed products. Along with the increase in population, the demand for consumers also increases, and the by-products of farming are increasing and being discharged into the environment. This is one of the critical research issues that need to be solved to ensure sustainability in agriculture. This review summarized recent studies on familiar sources of by-products in Vietnam, such as banana peels, citrus peels, dragon fruit skins, rice bran, and rice husks, and their potential in the food industry. Some solutions are also proposed to solve and turn this low-value raw material into a high-value product and serve a variety of products and consumers in the food industry. Especially after the COVID-19 pandemic, the by-products contain valuable and reusable biological resources. These compounds could be future applications to support improving the consumer's immune system and various health benefits. Processed and utilized by-products from food production could not only help increase incomes for farmers, especially in developing countries like Vietnam but also could aid in ensuring food security and sustainability in agricultural production.

Published: May 2023

Background: Depression is a common comorbid disease among patients with chronic kidney disease (CKD). Insomnia, a symptom related to these conditions, negatively impacts disease progression and quality of life. Unfortunately, no consensus has been reached concerning treatment guidelines and choices of antidepressants suitable for treating depression among patients with CKD.

Objectives: The study aimed to evaluate the efficacy to sleep quality, depressive symptoms, safety and tolerability of agomelatine and sertraline in treating major depressive disorder among patients with CKD.

Methods: A double-blinded randomized controlled trial was conducted in the Nephrology Unit, Department of Medicine, Phramongkutklao Hospital, Bangkok, Thailand. Patients with CKD and a diagnosis of major depressive disorder were randomly assigned to receive once-daily, fixed-dose sertraline 50 mg/d and agomelatine 25 mg/d. The treatment outcome was evaluated at 4 and 8 weeks. The Pittsburgh Sleep Quality Index score (PSQI) was used to measure sleep quality, and the Hamilton rating scale of depression, the Thai version (Thai HRSD-17), was used to evaluate depressive symptoms. Other outcomes included overall quality of life, side effects and tolerability.

Results: Agomelatine significantly improved sleep quality based on PSQI score throughout the observed period (p=0.002). Also, agomelatine more efficiently reduced depressive symptoms than sertraline (p=<0.001). In addition, patients receiving agomelatine as a treatment could continue their medication, whereas 52% of patients receiving sertraline discontinued because of side effects.

Conclusion: Agomelatine significantly improved sleep quality and tolerated well compared to sertraline.

Published: May 2023

La educación a distancia se presenta como una alternativa educativa con gran auge dado sus beneficios para adquirir un aprendizaje. Este aprendizaje precisa de un andamiaje enfocado en el estudiante como centro y protagonista. El estudiante presenta unas necesidades dado por su condición “humana” y vale la pena reflexionar el aplicar el “humanismo” a metodología de enseñanza. Tanto la administración, diseñador instruccional e instructor, entre otros, requieren, por consiguiente, tener las competencias habilidosas para transformar un proceso sistemático y en ocasiones solo centrado en el cumplimiento de dicho proceso, en uno que busque enfocarse en las necesidades del estudiante como individuo.
