Authors: Bensa Cheryl Pricilla
Published: June 2021

The plastic bag diet campaign has been carried out by many parties including government agencies, but the campaign is feared to only reach the cognitive stage, not a meaningful change in attitude. Many campaigns on the problem of plastic waste have been carried out from NGOs, the private sector, and the government, but what is wrong so as to the problem of plastic waste continues to occur? Why does the problem of plastic waste still stop at the campaign without a comprehensive behavior implementation of the community? The research method was a survey using quota sampling and descriptive. The population people in Balikpapan, Jakarta and Surabaya. The campaign to limit plastic bags can be successful if there is a synergy of the regulators; the government and NGOs, the private sector such as retailers, and the community. The related parties are expected to design a campaign in accordance with the social marketing model. Moreover, the related parties must also conduct formative research of the target behavior: the community about plastic waste and the extent to which the related parties must endeavor so that it can be known what audience benefits are most appropriate in formulating a campaign. In the implementation of social marketing, related parties have to clearly formulate the target behavior that exists so that people are not confused and have one voice. In addition, policies must also be upheld to support and maintain the results of social marketing to be sustainable. Moreover, educational and outreach programs that can change behavior about the environment will also help future generations to reduce pollution of plastic waste.

Authors: Nasucha Muchammad , Kertanegara Rizky
Published: June 2021

Currently, the rapid usage of the Internet as a tool or medium of communication and information, including media campaign to society, is popular to spread the idea(s), thought, even ideology. YouTube, as one of the popular video-sharing social media, is vivacious and potential to get the audience’s attention and responses accordingly to the design(s) like ABC as one of the brands of complementary food (sauce/ketchup) has done. This research tries to find the audience’s responses to gendered-relations campaign through the new media, particularly through social media (YouTube). Based on reader-response theory and using [dominantly] qualitative text online analysis, this research attempts to find the variety of the audience’s response to the Campaign. Finally, this research finds that basically, the responses are implicit and explicit. The explicit means that the icon like and unlike identifies the audience’s positive and negative responses. The implicit response appears in the comment section, both verbal and nonverbal (such as emoticon). We can catch many comments about gender relations. Even between wife-husband (spousal relationship), the dichotomy still exists and shows a negative-positive pole. The diverse responses/comments presented by the audiences seem to be influenced by several factors, such as values of the culture, education, family, environment, society, and religion. It seems that the campaign as a digital marketing strategy has affected the audiences to involve in spreading the idea, called as the word-of-mouth effect.

Authors: Vaioulis Alexandros , Bonotis Konstantinos , Perivoliotis Konstantinos , Kiouvrekis Yiannis , Gravas Stavros , Tzortzis Vasilios , Karatzas Anastasios
Published: June 2021

BACKGROUND:

Bladder cancer (BC) is one of the most common malignancies (4.5%of all newly diagnosed cases worldwide). Most of the new BC cases are diagnosed as non-muscle invasive BC (NMIBC), needing continuous follow up after primary endoscopic therapy. Adjuvant bladder therapy with chemo- or immuno- agents, apart from the initial diagnosis, the strict surveillance program and the risk of recurrence, may have a major impact on the patients’ physical and mental health.

OBJECTIVE:

We evaluated anxiety and quality of life (QoL) in patients who underwent surgery for NMIBC and followed a bladder instillation programme.

METHODS:

This is a prospective analysis of patients with histopathologically confirmed NMIBCs. Eligible were all adult patients with a single or multiple NMIBCs who underwent a transurethral tumor resection and followed a therapy with either BCG or Epirubicin instillations. The SF-36 questionnaire Physical and Mental health aspects were used for QoL assessment. Similarly, the STAI-Y was introduced for the state (STAI-Y1) and trait anxiety (STAI-Y2) evaluation.

RESULTS:

117 eligible patients were screened, with 108 entering finally the study; 9 patients were excluded due to disease recurrence. 17 patients (15.7%) received Epirubicin (Ta-T1, Low Grade tumors), whereas 91 patients (84.3%) received BCG (T1, High Grade). Regarding SF-36 Physical a 6 months decrease was followed by an improvement at 12 months ( p = 0.008). Similarly, an increase of the SF-36 Mental health score was identified ( p = 0.03). In contrast to STAI-Y2 scores ( p = 0.945), a long-term reduction of the state anxiety was identified ( p = 0.001). Preoperative SF-36 Physical was inversely correlated with age ( p = 0.029), while absence of alcohol was associated with lower mental health ( p = 0.003). Overall, patient characteristics, habits and the administered treatment did not affect the postoperative QoL and anxiety.

CONCLUSION:

Patient QoL and anxiety improved during follow up. Still, further larger scale studies are required to support our findings.
Association between baseline Controlling Nutritional Status score and clinical outcomes of patients with multiple myeloma
Authors: Zhou Xin , Lu Yan , Xia Jun , Mao Jingjue , Wang Jing , Guo Hongfeng
Published: June 2021

BACKGROUND: The Controlling Nutritional Status (CONUT) score, a novel immuno-nutritional index, was reported as a predictor of overall survival (OS) in some tumors. OBJECTIVE: We aimed to investigate the association between baseline CONUT Score and clinical outcomes in patients with multiple myeloma (MM). METHODS: We performed a retrospective analysis of 245 patients with MM. The CONUT score was determined prior to therapy. RESULTS: Among the entire cohort, the complete remission rate was markedly higher in the low-CONUT (⩽ 3) group compared to the mid-CONUT (4–9) group or high-CONUT (> 9) group (44.1% vs 25.8%, P= 0.039; 44.1% vs 12.5%, P= 0.002). Patients with CONUT score > 9 had significant poor prognosis, and CONUT score ⩽ 3 group showed better survival outcome than other groups in OS (P< 0.001). Besides, we stratified the patients by combining International Staging System (ISS) stage and CONUT score in a model, and found that CONUT score could improve the prognostic impact of ISS stages on OS. In multivariate analysis, older age (⩾ 70 years) and a high CONUT score (⩾ 4) were independent prognostic risk factors for OS. CONCLUSIONS: The CONUT score was a predictor of OS in MM patients especially in cases with both low ISS staging and CONUT score. The baseline CONUT score may be an early and practical indicator of the efficacy of anti-myeloma treatment.
Hip and ankle strength and range of motion in female soccer players with dynamic knee valgus
Authors: Jo Young Jin , Kim Young Kyun
Published: June 2021

BACKGROUND:

Dynamic knee valgus (DKV) is a known risk factor for acute and chronic knee injuries and is more frequently diagnosed in females. A real-time single-leg squat test (SLST) could screen for DKV to prevent injuries.

OBJECTIVE:

To compare the differences in lower extremity strength and range of motion (ROM) in female soccer athletes with and without DKV during an SLST.

METHODS:

Eighteen subjects with DKV (DKV group) and 18 subjects without DKV (control group) during a single-leg squat were included. Hip strength (flexion, extension, abduction, adduction, internal rotation, and external rotation) was measured with a hand-held dynamometer. Hip ROM (internal and external rotation), and ankle ROM (dorsiflexion with the knee flexed and extended) were measured. Independent t-test was used to compare the averages of the groups.

RESULTS:

There were significant differences in hip abduction to adduction strength ratio (DKV: 1.48 [Formula: see text] 0.3, control: 1.22 [Formula: see text] 0.26, [Formula: see text] 0.01) and ankle dorsiflexion with knee flexed (DKV: 17.22 [Formula: see text] 6.82, control: 21.22 [Formula: see text] 4.55, [Formula: see text] 0.05) and extended (DKV: 10.14 [Formula: see text] 4.23, control: 14.75 [Formula: see text] 3.40, [Formula: see text] 0.001) between the groups.

CONCLUSION:

The hip abduction to adduction strength ratio and gastrocnemius and soleus flexibility may be associated factors in dynamic knee valgus and therefore should be assessed and treated, if indicated, as a possible preventive measure in female athletes with this variation.
Experimental and numerical assessment of vertical accelerations during bow re-entry of a RIB in irregular waves
Authors: van der Eijk Martin , Wellens Peter
Published: June 2021

This paper presents the comparison of a self-conducted towing tank experiment with the simulation results of a calibrated state-of-the-art strip-theory method and a first-principles numerical method. The experiment concerns a Rigid Inflatable Boat (RIB) in moderate-to-high irregular waves. These waves result in bow emersion events of the RIB. Bow re-entry induces vertical accelerations which, in reality, can lead to severe injuries and structural damage. State-of-the-art methods for predicting the vertical acceleration levels are based on assumptions, require calibration and are often limited in application range. We demonstrate how the vertical acceleration as a function of time is found from a 3D numerical method based on the Navier–Stokes equations, employing the Volume of Fluid (VoF) method for the free surface, without any further assumptions or limitations. 2D+t strip theory methods like Fastship are based on the mechanics of wedges falling in water. The 3D numerical method that is part of the software ComFLOW is compared to previous research on falling wedges in 2D to investigate the effect of air and to find suitable grid distances for the 3D simulation of the RIB. The 3D RIB simulations are compared to Fastship and the experiment. With respect to the experiment, the ComFLOW simulations show a slight underestimation of the levels of heave and pitch. The underestimation of Fastship is larger. The prediction of acceleration in ComFLOW is hardly different from the experiment and a significant improvement with respect to Fastship. ComFLOW is demonstrated to predict acceleration levels better than before, which creates opportunities for using it in seakeeping optimization and for the improvement of methods like Fastship. The properties of the RIB and the experiment are available as open data at Wellens (2020).

Published: June 2021

Background: Socioeconomic factors are important contributors to brain health. However, data from developing countries (where social inequalities are the most prominent) are still scarce, particularly about hypertensive individuals. Objective: To evaluate the relationship between socioeconomic index, cognitive function, and cortical brain volume, as well as determine whether white matter hyperintensities are mediators of the association of the socioeconomic index with cognitive function in hypertensive individuals. Methods: We assessed 92 hypertensive participants (mean age = 58±8.6 years, 65.2%female). Cognitive evaluation and neuroimaging were performed and clinical and sociodemographic data were collected using questionnaires. A socioeconomic index was created using education, income, occupation (manual or non-manual work), and race. The associations of the socioeconomic index with cognitive performance and brain volume were investigated using linear regression models adjusted for age, sex, time of hypertension since diagnosis, and comorbidities. A causal mediation analysis was also conducted. Results: Better socioeconomic status was associated with better visuospatial ability, executive function, and global cognition. We found associations between a better socioeconomic index and a higher parietal lobe volume. White matter hyperintensities were also not mediators in the relationship between the socioeconomic index and cognitive performance. Conclusion: Socioeconomic disadvantages are associated with worse cognitive performance and brain volume in individuals with hypertension.

Authors: Bhutia Pema O. , Kewlani Pushpa , Pandey Aseesh , Rawat Sandeep , Bhatt Indra D.
Published: June 2021

BACKGROUND:

Genus Fragaria (family - Rosaceae), popular edible berry fruits with delicious flavor and considerable health benefits has many wild relatives in the Himalayan region.

OBJECTIVES:

The objective of the study was to characterize variability in morphology, physicochemical properties, phytochemicals, and antioxidant activity in wild Himalayan Strawberry, Fragaria nubicola along the ripening stages and among the genotypes.

METHOD:

Morphological and physicochemical properties, thiamine, carotenes, total phenolic content, phenolic compounds, total flavonoids, flavonols, tannins, anthocyanins, and antioxidant activity (ABTS, DPPH, and FRAP assays) were determined in four ripening stages of berry fruits.

RESULTS:

Morphological attributes (diameter, length, volume, and fresh weight of berries) have shown considerable variations among the genotypes and increased significantly ( p < 0.05) with the ripening stages. The physicochemical properties such as juice content, pH and moisture content also increased with the ripening, however, the pomace content decreased with the ripening. Anthocyanin content increased significantly ( p < 0.05) with ripening and reached at maximum level after full ripening. A successive decrease in free and bounded total phenolic, flavonoid, and flavonol contents was observed with the ripening except in total tannin content. However, a reverse trend of these phenolics was observed in juice along with the ripening. The antioxidant activity measured by three in vitro assays increased with the ripening. Phenolics were extracted higher in the acidified methanolic solvent (extracted free and bounded phenolics) as compared to methanolic solvent (extracted free phenolics). Phenolic compounds quantified by RP-HPLC analysis were extracted higher in acidified methanol as compared to methanol, except chlorogenic acid content.

CONCLUSION:

The results showed quantitative changes in free and bounded phenolics and morphological and functional traits along with the ripening. Also, this important genetic resource exhibited potential utility in the breeding of strawberry improvement programs and as an alternative resource of rich phytonutrients and antioxidants as a functional food.

Authors: Caron Nicholas S. , Anderson Christine , Black Hailey Findlay , Sanders Shaun S. , Lemarié Fanny L. , Doty Crystal N. , Hayden Michael R.
Published: June 2021

Background:

Therapeutics that lower mutant huntingtin (mHTT) have shown promise in preclinical studies and are in clinical development for the treatment of Huntington disease (HD). Multiple assays have been developed that either quantify mHTT or total HTT but may not accurately measure levels of wild type HTT (wtHTT) in biological samples.

Objective:

To optimize a method that can be used to resolve, quantify and directly compare levels of full length wtHTT and mHTT in HD samples.

Methods:

We provide a detailed quantitative immunoblotting protocol to reproducibly resolve full length wtHTT and mHTT in multiple HD mouse and patient samples.

Results:

We show that this assay can be modified, depending on the sample, to resolve wtHTT and mHTT with a wide range of polyglutamine length differences (ΔQs 22–179). We also demonstrate that this method can be used to quantify allele-selective lowering of mHTT using an antisense oligonucleotide in HD patient-derived cells.

Conclusion:

This quantitative immunoblotting method can be used to reliably resolve full-length HTT alleles with ΔQs≥22 and allows for direct comparison of wtHTT and mHTT levels in HD samples.

Authors: Liu Fuwei , Wang Yansen
Published: June 2021

The freezing pipe fracture can cause freezing wall to thaw and even lead to major accidents such as mine flooding easily, which seriously threatens the safety in construction. Therefore, scientific and effective comprehensive risk assessment for freezing pipe fracture is of great significance. In this work, a risk assessment method is put forward based on improved AHP-Cloud model with 19 evaluation indicators. First, the multi-dimension evaluation index system and evaluation model are established, on the basis of in-depth analysis of the risk factors that may lead to accidents. Second, synthesizing the normalization process and the improved analytic hierarchy process (AHP), the evaluation grade cloud and comprehensive evaluation cloud of freezing pipe fracture can be acquired by using the forward cloud generator. Finally, According to the max-subjection principle and the comprehensive evaluation method, we obtain the risk level of freezing pipe fracture. The model is applied to Yangcun Coal Mine. It has been verified that the risk assessment problem of freezing pipe fracture in freezing sinking can be successfully solved by the model we proposed. Above all, the study offers a new research idea for the risk management of freezing pipe fracture in freeze sinking.

Authors: Dobashi Yoshito , Ohmori Nobuaki
Published: June 2021

In this paper, we examined and confirmed the effectiveness of public involvement in improving accessibility in three selected railway projects. These are the Hankyu-Itami Station project, Fukuoka Nanakuma Subway project, and Sendai Tozai Subway project. As we had already previously analyzed the approaches and processes of the three projects through stakeholder interviews and literature reviews, we next carried out a satisfaction survey to collect passengers’ voices, including both persons with and without mobility difficulties. Through the survey, we found that passengers with mobility difficulties benefit more from accessible facilities that have been planned via public involvement. We also found that accessible facilities continue to provide barrier-free and universal design access over time. Judging from our findings, we support the view that public involvement is an effective approach to improving satisfaction in the usability of barrier-free and universal design facilities.

Medical recorders and health information are some of the health workers who are included in the "medical technical" group where the task of medical recorders and health information is to manage patient data into health information that is useful for decision making. Planning for the needs of health personnel must be following the needs in the field in terms of type, qualification, quantity, and procurement. Excess health personnel will result in unproductive use of work time, while a shortage of health workers will result in excessive workloads so that in planning the needs of health workers an analysis of the workload is required. This study was conducted to obtain information on the ideal number of medical record health personnel using workload calculations. This research method is based on the calculation method of Work Load Indicator Staff Need (WISN) through the implementation of a website-based information system at XYZ Hospital. Based on the results of this study, it shows that the ratio of <1 HR in the unit is not sufficient and not following the workload, namely the number of human resources in the Old Patient TPPRJ with a ratio value of 0.33; RJ coding ratio value 0.41; and Analysis with a ratio value of 0.38. Lack of officers at TPPRJ for Old Patients, RJ Coding, and Analysis resulted in poor service, so it is necessary to add medical personnel to that section when conditions are crowded.

Problem relevance. Due to the multi-departmental concepts and the different content of educational programs of schools and universities, a serious problem arises of the succession and continuity of the education system along the “vertical” in general and subject teaching in particular. Another didactic problem is the need to ensure interdisciplinary connections of basic courses in the traditional disciplinary model of the educational process for more effective and expedient formation of certain student’s competencies sets. In this regard, it is of interest to create new organizational and meaningful approaches to training specialists without a significant restructuring of the traditional educational process.

The purpose of the article is to substantiate a collaborative model of subject training of students in a school-university cluster of disciplines, which ensures the succession and continuity of education at school and university.

Methodological basis. On the example of three disciplines “Programming”, “Computanional Methods”, “Information Technologies in Education”, a cluster model of teaching schoolchildren and students in the direction of training “Mathematics and Computer Science” has been designed and implemented. A feature of the considered school-university cluster of disciplines is a unified methodological base of target, meaningful and didactic elements that form and develop the calculative-algorithmic component of the computational thinking of students. The basis of the means and methods of teaching in the cluster is made up of cognitive techniques and a platform of “computational and algorithmic primitives” — solving elementary task template. A recursive approach is used in the methods of cluster subject teaching of schoolchildren and students.

Results and Conclusions. The model of the created disciplinary cluster “Programming — Computanional Methods — Information Technologies in Education” contributes to the formation and development of the calculative-algorithmic component of the computational thinking of schoolchildren and students, and also forms their assigned groups of competencies. The school-university cluster of disciplines ensures real succession and continuity of school and university education, without unnecessary, sometimes artificial, labor-intensive additional organizational and methodological means and techniques. The approach under consideration can be used to create clusters of disciplines in various educational areas, allowing their meaningful collaboration and forming given competencies sets and schoolchildren’s and student’s cognitive abilities.

Published: June 2021

The article discusses the capabilities of the Minecraft: Education Edition (Minecraft EDU) platform, built on the ideas of gamification, to motivate schoolchildren to study informatics. It describes how to work with the platform (creating an account, importing worlds, creating programs); basic concepts associated with the platform; approximate planning of lessons of the thematic section "Algorithmics" for the sixth grade; general idea of work in the classroom using the platform. The materials of two lessons are presented in detail: the first is focused on acquainting students with Minecraft EDU, the basic rules and tools of this platform; the second is focused on compose linear programs, acquaintance with such concepts of informatics as "algorithm", "executor", "system of commands of the executor". For each of the two lessons, the game world, specially prepared by the teacher, is described in detail. The results obtained by the author when testing these materials are formulated.
Biztonságtechnikai megoldások az Óbudai Egyetem Népszínház utcai kampuszán

Napjainkban az egyetemeknek szükségszerű olyan modern biztonságtechnikai megoldásokat alkalmazniuk, amely által garantálni tudják az ott tartózkodó hallgatók biztonságát. Tudvalevő, hogy az oktatási intézmények működéséből kifolyólag igen gyakran nagy számban tartózkodnak az épület falain belül hallgatók és ott dolgozó tanárok. Az ő biztonságuk mindennél fontosabb. Elég csak kitekinteni külföldre, ahol sajnálatos módon, az egyetemeken többször is előfordult komoly incidens, úgy, mint lövöldözés, gyilkosság. Ebből kifolyólag került sor az Óbudai Egyetem biztonságtechnikai megoldásainak a megvizsgálásra, hiszen jelen esetben egy olyan neves oktatási intézményről van szó, amely az évek során számos hallgatónak biztosított tanulási és továbbképzési lehetőséget. A kutatás részleteiben feltárta azt, hogy az Óbudai Egyetemen igen komoly biztonságtechnikai megoldások kerültek kiépítésre, így feltételezhetően az ott tartózkodók biztonságban érezhetik magukat.
Hazai üzemelő és távlati parti szűrésű ivóvízbázisok mennyiségi és minőségi értékelése
Authors: Goda Zoltán
Published: June 2021

Hazánk ivóvíztermelésének több, mint 30%-a üzemelő parti szűrésű ivóvízbázisokból származik és a legjelentősebb távlati ivóvízbázisok is folyóink homokos-kavicsos teraszain kerültek kijelölésre. A parti szűrésű vízszerzés mindmáig az egyik leghatékonyabbnak és leggazdaságosabbnak tekinthető, más vízszerzési módokkal összehasonlítva számos előnnyel rendelkezik. A parti szűrésű vízbázisok szűrőrétegében végbemenő mechanikai, biológiai és fizikai-kémiai folyamatok természetes úton zajlanak le, ezáltal jelentős költségek takaríthatók meg. A szerző e cikkben rámutat a parti szűrés folyamatainak máig ismeretlen területeire, veszélyeztető tényezőire, valamint arra a tényre, hogy az elmúlt két évtizedben sérülékenynek minősített és részben védelembe helyezett parti szűrésű vízbázisaink mennyiségi és minőségi mutatóinak figyelemmel követése és monitorozása kiemelt jelentőséggel bír, hiszen vízellátásunk jelentős pillérét képezik. A parti szűrésű vízbázisok értékelésén túl a szerző rávilágít a vízbázisvédelem hiányosságaira, valamint felhívja a figyelmet új, napjainkban jelentkező kockázati tényezőkre.

A magyarországi vasúthálózat redundanciáját biztosító vonalszakaszok
Authors: Tóth Bence
Published: June 2021

Egy hálózat zavarállóságát jól jellemzi, hogy szükség esetén rendelkezésre állnak-e megfelelő kapacitású kerülőutak. Ezen kerülőutak meghatározásához a magyarországi vasúthálózatot egy élsúlyzott irányított gráffal modelleztem. Az egyes vonalszakaszok sérülése esetén a hálózat forgalmának elterelhetőségét az ún. redundanciaindexszel jellemeztem. Az eredmények azt mutatják, hogy a magyarországi vasúthálózatban megvannak azok az útvonalak, melyek elégséges tartalék kapacitást hordozhatnának a zavarok kezelésére. Ezek a vonalszakaszok azonban többségükben egyvágányúak, nem villamosítottak és a megengedett sebesség rajtuk is igen alacsony. Ezért a hálózat jelen állapotában nem lenne képes kezelni a nagy forgalmú fővonalak sérüléseit. A cikkben bemutatom, mely vasútvonalak célzott fejlesztésével lenne jelentősen csökkenthető a hálózat zavarérzékenysége.
