Published: June 2021

Sektor Pariwisata merupakan sektor yang sangat penting bagi masyarakat Bali. Walaupun wilayah Bali terdiri dari lahan pertanian, lahan kering serta perairan seperti pantai, danau,dan sungai, namun sebagian besar masyarakat Bali menggantungkan kehidupannya dari sektor Pariwisata. Pandemi Covid -19 memberikan pukulan yang sangat keras bagi semua sektor termasuk sektor pariwisata. Virus Corona yang sangat membahayakan kesehatan manusia telah menginfeksi jutaan penduduk di seluruh dunia. Penyebaran virus Corona melalui interaksi dengan orang yang telah terinfeksi menyebabkan adanya kebijakan pembatasan jarak sosial, serta anjuran untuk melakukan aktivitas di rumah. Kebijakan yang dibuat untuk mencegah efek domino dan memutus penyebaran virus ini perlahan namun pasti telah menghantam sektor pariwisata. Tidak adanya kunjungan wisatawan mancanegara serta pembatasan wilayah di Indonesia menyebabkan berbagai usaha pariwisata mengalami dampak yang luar biasa. Hotel-hotel dengan hunian 0 % di tutup untuk sementara waktu. Para karyawan hotel, travel dan usaha perjalanan wisata, restoran, serta sektor lainnya pun dirumahkan dan sebagian besar kehilangan pekerjaan. Ambruknya sektor pariwisata di Bali menyebabkan merosotnya perekonomian Bali. Tidak saja pekerja disektor pariwisata, namun para petani yang memasok hasil pertaniannya ke hotel maupun restoran, nelayan yang menjual hasil tangkapan ikannya ke hotel, serta menengah (UMKM) terutama yang menghasilkan cendera mata ikut terkena imbasnya. Hal ini tentu tidak boleh dibiarkan terus berlarut-larut karena akan mempengaruhi kelanjutan hidup masyarakat Bali. Penelitian ini bertujuan untuk mengetahui dampak yang di timbulakn oleh COVID-19 terhadap sektor parisata beserta Upaya-upaya yang dapat dilakukan untuk pemulihan pariwisata dalam upaya memulihkan perkonomian masyarakat Bali agar masyarakat Bali dapat melanjutkan kehidupan seperti sediakala

Published: June 2021

Objectives: This study aims to investigate the association of COL4A1 and COL4A2 gene polymorphisms with susceptibility to risk of developing cerebral palsy (CP) and severity of CP.
Patients and methods: Between December 2016 and June 2017, a total of 176 patients with CP (101 males, 75 females; mean age 71.8±37.9 months; range, 24 to 184 months) and age-, sex-, and ethnically-matched 178 (90 males, 88 females; mean age 69.3±55.2 months; range, 24 to 214 months) controls were included. Two polymorphisms of COL4A1 (rs1961495) and COL4A2 (rs9521733) genes were typed from genomic deoxyribonucleic acid. Genotype distributions and allelic frequencies were compared between the patient and control groups. Gross Motor Function Classification System, the use of medical drugs, type of involvement, number of affected limbs, accompanying conditions, birth weight, gestational age, and magnetic resonance imaging (MRI) findings were used to evaluate the disease severity and their relationships with the COL4A1 and COL4A2 gene polymorphisms.
Results: There was no statistically significant difference between the groups in terms of genotype distribution and allele frequency of COL4A1 and COL4A2 gene polymorphisms (p>0.05). In addition, there was no relationship between severity of CP and two gene polymorphisms (p>0.05). A significant association was detected between the COL4A2 polymorphism and growth retardation in CP. The TT genotype (57.1%) and T allele (76.2%) were higher, compared to CC (4.8%) and CT genotypes (38.1%) and C allele (23.8%) in patients with CP with growth retardation (p=0.03 for genotype and p=0.01 for allele frequency).
Conclusion: These findings suggest that COL4A1 and COL4A2 gene polymorphisms are not associated with susceptibility to CP in a group of Turkish populations, although COL4A2 gene polymorphism may be associated with growth retardation in patients with CP.
Influence of Ship Design Complexity on Ship Design Competitiveness

Published: June 2021

Complexity is discussed in design literature mainly through its negative and in some cases positive consequences. This article critically reviews and elaborates the effects of complexity on competitiveness in ship design, its directionality, and magnitude. The article introduces a model for the measurement of ship design complexity and ship design competitiveness based on predefined factors. Archival data of 100 ship design projects from eight different Norwegian designers are used as case study. Multivariate data analysis techniques are employed to study the research model. The results show a significant correlation between complexity and competitiveness in ship design, where the magnitude and directionality of influence vary among different complexity factors. Our findings provide a basis for enhancing complexity management in ship design.

Introduction
Continual technology improvements and market volatility with its associated uncertainties have a significant impact on and partly change ship design customers’ expectations. To be successful in such a market, not only does it require the development of competitive products but also the accompanying work processes and the organization or firm framing the development of the vessel solution are involved. Ulstein and Brett (2015) define ship design competitiveness in terms of doing the right thing (effectiveness), doing the right thing right (efficiency), and with the right resources (efficacy) to cover product, process, and firm aspects of competitiveness. To improve their success, ship design companies typically tend to focus on the introduction of new technologies, and, in some cases, extra functional capabilities, which have led to large and complex vessels over the years. To a lesser extent, ship designers have put emphasis on the overall needs of customers. Securing a higher overall performance yield of the ship design solution than peer vessels out in the market is not a common practice among ship designers; they rather focus on a typical and traditional subset of performances. The implications and the consequences of such strategies in ship design have led to a growing need for a new set of design tools and project-making skills, a more extensive design process with different disciplines involved, and many iterations in the design development process.

Published: June 2021

The article proposes the validation of a research tool, aimed at measuring the professional resilience of teachers. In scientific debate, the use of the resilience construct and an instrument aimed at detecting it is quite frequent, but there are few instruments to contextualize resilience in a strictly professional context. Professional Resilience of Teachers Scale [Scala di Resilienza Professionale degli Insegnanti – SRPI] can be usefully applied in stress and trauma situations that can be linked to personal experiences or emergency situations that cause teachers to face numerous unforeseen problems in their work and to implement, i.e. appraisal and coping strategies related to the concept of resilience. The SRPI was administered to a sample of 556 teachers from all school orders distributed throughout the national territory. Correlational and factor analysis made it possible to optimize the instrument, reducing the number of items from 39 to 28 and identifying the factors most involved in the proposed construct. The research confirmed high values of internal (α = .897).
Accordo assoluto tra valutazioni espresse su scala ordinale
Authors: Bove Giuseppe , Marella Daniela 
Published: June 2021

Many methods for measuring agreement among raters have been proposed and applied in many domains in the areas of education, psychology, sociology, and medical research. A brief overview of the most used measures of interrater absolute agreements for ordinal rating scales is provided, and a new index is proposed that has several advantages. In particular, the new index allows to evaluate the agreement between raters for each single case (subject or object), and to obtain also a global measure of the interrater agreement for the whole group of cases evaluated. The possibility of having evaluations of the agreement on the single case is particularly useful, for example, in situations where the rating scale is being tested, and it is necessary to identify any changes to it, or to request the raters for a specific comparison on the single case in which the disagreement occurred. The index is not affected by the possible concentration of ratings on a very small number of levels of the ordinal scale.

Published: June 2021

Coronavirus Disease (Covid-19) pandemic influenced education systems throughout the world, including in Indonesia. It makes the universities and schools go online for their teaching-learning process. Therefore, mobile learning can be an alternative solution to carry out the teaching and learning process as suggested by the government. The purpose of this study was to explore empirically mobile learning acceptances based on Technology Acceptance Model (TAM) with satisfaction as the mediating variable. The population of this study is 250 Economics Education students at Universitas Negeri Semarang. The sample was taken by purposive sampling with the criteria of students who have used mobile learning in supporting their learning activities. Structural Equation Model (SEM) with AMOS 24 was performed to analyze quantitative data. The results showed that from 6 hypotheses, there are 5 accepted hypotheses; they are; perceived ease of use, perceived usefulness, and perceived interactivity have positive and significant effects on the intention to use mobile learning. The mediating variable (satisfaction) is successful to strengthen the influence between perceived ease of use and intention; and perceived usefulness and intention. However, satisfaction is rejected to mediate perceived interactivity and intention to use. Stakeholders should improve students’ satisfaction in their learning activities. The limitation of this study was the research results cannot be easely generalized in other contexts. In the future, other researchers can add other factors to examine better technology acceptance.

Published: June 2021

This study examined the impact of a program based on problem-solving in mathematical problem-solving among 10th grade students. The sample of this study consisted of (89) male and female students; Wadi Bani Kharous Basic Education School and Om Hakeem Basic Education School located in AlBatina South Governorate (Oman). The study followed the quasi-experimental research design with experimental group consisted of (48) students, and control group consisted of (41) students. The instructional materials of Polynomial and Algebraic Functions Unit and Trigonometric Functions Unit for Grade 10th were designed according to a program based on problem-solving. The problemsolving test was valid and reliable. The findings indicated that there were significant statistical differences in mathematical problem-solving test between the experimental and control group due to teaching method in favor of experimental group. The findings indicated that there were no significant statistical differences in mathematical problemsolving test between male and female students. The findings also indicated that there were statistical significance differences in mathematical problem-solving test due to the interaction between and teaching method and gender. The study recommended organizing training workshops for mathematics teachers to introduce programs based on problem solving, training them to build educational programs based on problem solving, and urging them to adopt it due to the positive impact it has shown in teaching mathematics.

Published: June 2021

Analytical thinking skills are critical thinking skills and higher-order thinking skills that meet students’ demands in the 21st century. This study aims to analyze the student’s analytical thinking skills in the natural sciences, particularly in new and renewable energy. This study was a sequential explanatory design with quantitative and qualitative methods. Data was obtained from the interview, observation, and essay test to students of the Madrasah Ibtidaiyah Teacher Education Program Study at IAIN Surakarta (Indonesia) to determine a characteristic of the students’ analytical thinking skills. The results showed that the mean scores of the pre-test, post-test, and effect size were 54.34, 74.91, and 2.91, respectively. These results revealed that analytical thinking skills in the concept of new and renewable energy in the experimental group were higher than the control group. Innovative learning like PBL had a potential as the alternative method to increase the analytical thinking skills of student. These findings were expected to provide a general characteristic to lecturers and researchers on the students’ analytical thinking skills in higher education in the natural sciences, particularly in the concept of new and renewable energy by implementing the Problem Based Learning (PBL) model.
La didattica a distanza durante il lockdown in Italia: il punto di vista delle famiglie
Authors: Szpunar Giordana , Cannoni Eleonora , Di Norcia Anna 
Published: June 2021

Lockdown due to Covid-19 sanitary emergency causes a sudden break for scholar, social, cultural activities and sports. The aim of this work was to highlight changes in habits of life for children and teenagers with a particular focus on school activities. An on-line questionnaire was administrated to 5022 parents of children aged from 3 to 18 years. Results showed that secondary schools were able to guarantee at least hours of on-line lessons for half of the ordinary timing of schools. For preschooler and primary school, it seems that the recommended attention to maintain relations between the class group was less respected. So it seems that, during lockdown, children and teenagers were exposed to poverty of education and deprivation of social relationships. Probably due to lack of an adequate training for teachers, distance learning did not favored didactics strategies different from the traditional ones above all for preschool and primary schools.

Published: June 2021

Background
Cervical cancer (CC) is the fourth leading cause of death from neoplasms in women and is caused by the human papilloma virus (HPV). Several methods have been developed for the screening of cervical lesions and HPV; however, some socio-cultural factors prevent women from undergoing gynecological inspection, which results in a higher risk of mortality from cervical cancer in certain population groups as indigenous communities. This study aimed to compare the concordance in HPV detection from urine and cervical samples, to propose an alternative to cervical scraping, which is commonly used in the cervical cancer screening.

Methodology
The DNA from cervical scrapings and urine samples was extracted using the proteinase K method followed by precipitation with alcohol, phenol andchloroform; a modification of the proteinase K method was developed in the management of urine sediment. Viral genotyping was performed using INNOLipa.

Results
The study population consisted of 108 patients from an indigenous population at southern Mexico, 32 without squamous intraepithelial lesions (NSIL) and 76 with low squamous intraepithelial lesions (LSIL). The majority of NSIL cervical scrapes were negative for HPV (90.63%), whereas more than half of LSIL cases were high-risk HPV positive (51.32%), followed by multiple infection by HR-HPV (17.11%), and multiple infection by LR- and HR-HPV (9.21%). No statistically significant relationship between the cytological diagnosis and the HPV genotypes detected in the urine samples was observed. A concordance of 68.27% for HPV positivity from urine and cervical samples was observed. Similarly, a concordance of 64.52% was observed in the grouping of HPVs by oncogenic risk. HR-HPV was detected in 71% of the urine samples from women with LSIL diagnosis, which suggests that HR-HPV detected in a urine sample could indicate the presence or risk of developing SIL.

Conclusion
HR-HPV detection in urine samples could be an initial approach for women at risk of developing LSIL and who, for cultural reasons, refuse to undergo a gynecological inspection.
A seven-lncRNA signature for predicting Ewing’s sarcoma
Authors: Chen Zhihui , Wang Xinyu , Wang Guozhu , Xiao Bin , Ma Zhe , Huo Hongliang , Li Weiwei 
Published: June 2021

Background
Long non-coding RNAs (lncRNAs) are a class of non-coding RNAs with unique characteristics. These RNA can regulate cancer cells’ survival, proliferation, invasion, metastasis, and angiogenesis and are potential diagnostic and prognostic markers. We identified a seven-lncRNA signature related to the overall survival (OS) of patients with Ewing’s sarcoma (EWS).

Methods
We used an expression profile from the Gene Expression Omnibus (GEO) database as a training cohort to screen out the OS-associated lncRNAs in EWS and further established a seven-lncRNA signature using univariate Cox regression, the least absolute shrinkage, and selection operator (LASSO) regression analysis. The prognostic lncRNA signature was validated in an external dataset from the International Cancer Genome Consortium (ICGC) as a validation cohort.

Results
We obtained 10 survival-related lncRNAs from the Kaplan-Meier and ROC curve analysis (log-rank test P < 0.05; AUC >0.6). Univariate Cox regression and LASSO regression analyses confirmed seven key lncRNAs and we established a lncRNA signature to predict an EWS prognosis. EWS patients in the training cohort were categorized into a low-risk group or a high-risk group based on their median risk score. The high-risk group’s survival time was significantly shorter than the low-risk group’s. This seven-lncRNA signature was further confirmed by the validation cohort. The area under the curve (AUC) for this lncRNA signature was up to 0.905 in the training group and 0.697 in the 3-year validation group. The nomogram’s calibration curves demonstrated that EWS probability in the two cohorts was consistent between the nomogram prediction and actual observation.

Conclusion
We screened a seven-lncRNA signature to predict the EWS patients’ prognosis. Our findings provide a new reference for the current prognostic evaluation of EWS and new direction for the diagnosis and treatment of EWS.

Published: June 2021

Objectives
To assess the knowledge about cervical cancer and HPV infection and the awareness towards and perceived barriers of HPV vaccination amid medical students in Jordan.

Methods
The present study is a cross-sectional survey that was conducted for a period of three months in the College of Medicine at six different universities in Jordan. Third-year to sixth-year students from these medical colleges in Jordan were invited to participate in the study.

Results
There were 504 students that took part in the study with 42.3% being males and 57.7% females. The mean knowledge score of students in our survey was 21.4 ± 4.4 out of 34, which was categorized as a moderate level of knowledge regarding cervical cancer and HPV. Only 40.5% knew about the availability of the HPV vaccine in Jordan, and 65.9% accepted the idea that it is necessary to introduce the HPV vaccine for school girls in Jordan.

Conclusions
This study highlights that there is inadequate knowledge about cervical cancer and its screening among medical students in Jordan. Despite the limited awareness about the HPV vaccine among the study’s participants, there is a favorable opinion towards the introduction of the vaccine for school girls in Jordan. The data provide a benchmark on the level of knowledge about cervical cancer and awareness about HPV, which can be used to formulate an effective awareness program.
