Amaç: Bağırsak duvar kalınlık artışı olan olgulardaki bağırsak duvar özellikleri ve bilgisayarlı tomografi (BT) bulgularının bağırsak obstrüksiyonunun etiyolojisini belirlemedeki rolünü araştırmaktır.

Gereç ve Yöntem: Ocak 2015 ile Eylül 2016 tarihleri arasında hastanemize başvuran ve BT incelemelerinde bağırsak duvar kalınlaşmasının eşlik ettiği bağırsak obstrüksiyonu mevcut olguların incelemeleri retrospektif olarak değerlendirildi. Bağırsak duvar kalınlığı, arteriyel ve portal venöz faz kontrastlı görüntülerde bağırsak duvar atenüasyonu ölçümleri yapıldı. İnce bağırsak feçes işareti, asit, lenfadenopati, tarak işareti, mezenterik ödem, mezenterik damar trombozu varlığı kaydedildi. Bağırsak obstrüksiyonu nedenleri neoplazi, adhezyon, iskemi ve inflamatuvar bağırsak hastalığı (İBH) olarak dört ana gruba ayrıldı. Gruplar arasında karşılaştırma Mann-Whitney U testi kullanılarak yapıldı. Etiyoloji ve değişkenler arasındaki ilişkinin değerlendirilmesinde Pearson ki-kare testi kullanıldı. Bağırsak duvar kalınlığı ve bağırsak duvar atenüasyonu oranı göz önüne alındığında obstrüksiyon etiyolojisini değerlendirme amacıyla ROC analizi yapıldı.

Bulgular: Bağırsak obstrüksiyonu ile birlikte bağırsak duvar kalınlık artışı olan 63 olgu (40 erkek, 23 kadın; ortanca yaş: 62) saptandı. Bağırsak duvar kalınlığı göz önüne alındığında neoplazi-adezyon, neoplazi-İBH ve neoplazi-iskemi gruplarının karşılaştırılmasında istatistiksel olarak anlamlı fark saptandı. Bağırsak duvar kalınlığı ≥9,5 mm olan olgularda neoplazi tanısı için duyarlılık %85,7, özgüllük %92,5 olarak bulundu. Bağırsak duvar atenüasyonu oranı yönünden yapılan değerlendirmede iskemi ve diğer gruplar arasında anlamlı fark saptandı. Bağırsak duvar atenüasyonu oranı ≤-0,5 olan olgularda iskemi tanısı için duyarlılık %90,9, özgüllük %74,4 olarak tespit edildi. Lenfadenopati, feçes işareti, tarak işareti, damar trombozu varlığı yönünden grupların karşılaştırılmasında anlamlı farklar saptandı (p
Heterogeneity of Learners’ Behavioral Patterns of Watching Videos and Completing Assessments in Massive Open Online Courses (MOOCs): A Latent Class Analysis
Authors: Kang In Gu
Published: December 2020

Massive open online courses (MOOCs) have been touted as an effective way to make higher education accessible for free or for only a small fee, thus addressing the problem of unequal access and providing new opportunities to young people in middle and low income groups. However, many critiques of MOOCs have indicated that low completion rates are a major concern. Using a latent class analysis (LCA), a more advanced methodology to identify latent subgroups, this study examined the heterogeneity of learners’ behavioral patterns in a MOOC, categorized them into distinctive subgroups, and ultimately determined the optimal number of latent subgroups in a MOOC. The five subgroups identified in this study were: completing (6.6%); disengaging (4.8%); auditing (4.6%); sampling (21.1%); and enrolling (62.8%). Results indicated this was the optimal number of subgroups. Given the characteristics of the three at-risk subgroups (disengaging, sampling, and enrolling), tailored instructional strategies and interventions to improve behavioral engagement are discussed.

Published: December 2020

Steinernema feltiae belongs to the feltiae-kraussei-oregonensis group, clade III, and is an ubiquitarian species of entomopathogenic nematode. It is found in all types of soil and in all types of habitat. Species identification in the entomopathogenic nematodes genera Steinernema is a very complex task, given the broad variability of both morphological and biological traits within populations of a single species. To accomplish this, molecular techniques have been adopted which, however, require additional knowledge. Particularly relevant would be the possibility of testing in a reliable way the variability between different populations of the same species, which might represent different strains with different biological properties. During numerous samplings in Italy, several strains of S. feltiae were isolated. In this paper we analyze the intraspecific variability of the main morphometric and biological data of juveniles and males of 50 Italian populations of S. feltiae. The aim of our work was to determine if morphometric and biological analysis were useful to identify characters having significant diagnostic value, allowing to reliably discriminate among strains. Seven characters routinely computed for morphology (5 morphometrics for infective juveniles, spicula and gubernaculum shapes for males) and 2 biological performances (time to achieve adult stage, reproduction and progeny) were considered. The results showed extreme variability from both morphological and biological points of view

Authors: Tallo Fransiska Rima , Narmada Ida Bagus , Ardani I. G. A. Wahju
Published: November 2020

Background: Previous studies on root resorption were reviewed by panoramic radiographs. Cone-beam computed tomography (CBCT) showed that 41.5% of teeth experienced resorption when panoramically examinated, while 68% of teeth experienced resorption when the examination method used was CBCT. Root resorption occurs in the maxillary central incisor (as much as 74%) and in the maxillary lateral incisor (as much as 82%). The maxillary canines have the most resorption, followed by the lateral maxillary incisors. Purpose: The aim of this study was to determine the differences of apical resorption in anterior maxillary teeth before and after orthodontic treatment in skeletal Class I/II cases of extraction. Methods: Samples from this study were the results of panoramic photographs of 50 patients treated by fixed orthodontic appliances at the Dental and Oral Hospital Airlangga University. These were selected according to the sample criteria. The evaluation method consists of measuring root and crown lengths with a digital application (RadiAnt DICOM Viewer). Subsequently, the measurements were evaluated using CBCT images. Results: The data were statistically analysed using normality tests with Shapiro–Wilk and Kolmogorov–Smirnov tests. Based on the results of paired sample tests, it was found that every treatment group had significant differences in the average length of the crowns and roots, with a result of p=0.000 (p<0.05). Conclusion: The use of CBCT is considered quite effective and accurate in evaluating root resorption compared to panoramic photographs.

Authors: Sumiyana Sumiyana
Published: December 2020

This research critiques Sumiyana (2007a) that is actually weak methodological research design. Sumiyana (2007a) investigates trading and nontrading periods return only, or it doesn’t split intra-day return into short interval period. Although Sumiyana (2007a) found strongly the phenomenon of the Monday effect, but it could not capture the inside occurrence in the intra-trading periods. This study examines the day of the week and Monday effect phenomena in the Indonesian Stock Exchange using intraday data in every 30 minutes interval. Samples of the data are the firms listed in LQ45. Sequentially, samples are filtered to stocks that actively traded in the Indonesian Stock Exchange based on trading frequency in observation period from January to December 2006. This study uses regression analysis with multiple dummies constructed by separating trading periods in every day into 12 return periods. This research finds that day of the week phenomena occur consistently in Indonesian Stock Exchange, but the occurrence are not evenly in the same day. In addition, this study concludes that Monday effect exists partially and incidentally only.

This paper examines the investor reaction to earnings announcement around publication dates. This paper divides into two categories. There are the positiveearning announcements which include EPS increasing, and the negative-earning announcements which consist EPS decreasing. The examination of content and efficient market hypothesis used event study. We propose one hypothesis as positifearnings announcement and negative-earnings announcement correlate to stock price reactions in IDX. The sample are the 29 companies from LQ 45 that release the annual earnings of year 2004-2006. The earnings announcement date is taken from Indonesian Securities Supervisory Agency (Bapepam). Statistical test with standard error of estimate (SEE) was used to test the abnormal return during event periods. The results show that investor do not respond significantly to the positive and negative earnings announcement at the announcement dates. In addition, earning announcements suggest information contents to capital market. Finally, the empirical result is contrary to the finding of Ball and Brown (1968), Foster (1977), and Hayn (1995). However, this evidence supports the Lako’s studies (2002a, 2002c).

A Multi-Objective Decision-Based Solution (MODM) for Facility Location-Allocation Problem Using Cuckoo Search and Genetic Algorithms
Authors: Shimi Amir , Ebrahimi Dishabi Mohammad Reza , Azgomi Mohammad Abdollahi
Published: November 2020

Considering the significant advancements in autonomous vehicle technology, research in this field is of interest to researchers. To automatic parking, controlling steer angle, gas hatch, and brakes need to be learned. Due to the increase in the number of cars and road traffic, car parking space has decreased. Its main reason is information error. Because the driver does not receive the necessary information or receives it too late, he cannot take appropriate action against it. This paper uses two phases: the first phase, for goal coordination, was used genetic algorithms and the Cuckoo search algorithm was used to increase driver information from the surroundings. Using the Cuckoo search algorithm and considering the limitations, it increases the driver’s level of information from the environment. Also, by exchanging information through the application, it enables the information to reach the driver much more quickly and the driver reacts appropriately at the right time. The suggested protocol is called the MODM-based solution. Here, the technique is assessed through extensive simulations performed in the NS-3 environment. Based on the simulation outcomes, it is indicated that the parking system performance metrics are enhanced based on the detection rate, false-negative rate, and false-positive rate.

Examining College Music Majors’ Perceived Barriers and Motivation to Exercise
Authors: Seitz Matthew W. , Levy Jacob J. , Murphy Barbara A.
Published: December 2020

Previous research has revealed music majors, in general, do not identify as exercisers, subjecting them to various health risks. Influenced by self-determination theory, the current study examined exercise motivation and self-efficacy in overcoming barriers to exercise in relation to
number of times per week collegiate music majors reported they engaged in physical exercise. One hundred six college music majors completed a demographic questionnaire regarding their participation in marching music activities and how many days per week they engaged in physical exercise. They
also completed two standardized questionnaires that assessed their motivation to exercise (i.e., Behavioural Regulation in Exercise Questionnaire-2) and their confidence in overcoming barriers to exercise (i.e., Barriers Specific Self-Efficacy Scale). Results indicated that music majors who
espoused a stronger identified motivation to exercise and had greater self-efficacy in their perceived ability to overcome barriers to exercise reported a greater frequency of exercise engagement. Sex difference were also found, with female music students being less confident (than their male
counterparts) in their ability to overcome barriers to exercise. These findings highlight the motivations, obstacles, and perceptions of exercise in the music culture, providing a helpful start for comprehending what drives individuals in this domain.

Published: December 2020

AIMS: Although the significance of upper-body posture in relation to piano performance has often been highlighted, the role of experience remains unclear. The aim of this study was to examine selected upper body posture parameters in adolescent piano students of different performance
level (beginners vs advanced). METHODS: Thirteen (13) adolescent piano students (14.7±0.5 yrs; 7 beginners and 6 advanced) volunteered. They all performed two specific major scales (G-major and E-major) in five octaves in two predetermined different tempi (slow and fast). An upper body
biomechanical model consisting of 27 reflective markers was applied on specific bony landmarks. A 10-T camera Vicon system running Nexus 2 was employed to capture upper body motion—-a) sway of the trunk in relation to the instrument, b) finger/hand sway over the keyboard, c) overall
hand movement, and d) spinal angles—-at selected moments of four different performances. RESULTS: Beginners demonstrated more trunk sway than their advanced counterparts (p<0.05), more finger/hand sway (p<0.05), more overall hand movement (p<0.05), and more flexed spinal angles
at the start of their performance (p<0.05). Most of these differences appeared in the G-fast performances, whereas the G-slow equivalents revealed no differences. CONCLUSION: Less-experienced piano players are characterized by more movement in their trunk posture and more upper limb activity
than their more advanced colleagues. Future research should examine whether interventional programs designed to alter upper-body posture would have beneficial effects in piano performance.

Published: December 2020

AIMS: Professional ballet dancers are at risk for degenerative knee cartilage changes. In the current study, we evaluated the knee cartilage with T2 mapping methods in professional ballet dancers and healthy controls and investigated possible differences of T2 values between these groups.
METHODS: We included healthy dancers with 5−20 years of professional ballet dancing experience and sex-matched healthy controls without knee pathology. T2 values of the knee cartilage were measured from axial, coronal, and sagittal images. The values were measured by free hand region
of interest (ROI). RESULTS: The study population consisted of 44 people (22 dancers, 22 controls), with mean age of 25.57 ± 5.53 yrs. We found no significant relationship between sex and T2 values. We detected a significant positive correlation between age and T2 values for patellofemoral
joint cartilage. T2 values of patellofemoral and tibiofemoral joints of dancers were significantly higher. Mean T2 values of patellofemoral joint were around 32 in all planes in dancers and around 12 in controls (p<0.05). Mean tibiofemoral joint values in dancers were around 39 and around
32 in controls (p<0.05). CONCLUSIONS: T2 values of knee cartilage were higher in professional ballet dancers. T2 mapping method can reveal knee cartilage changes successfully in professional ballet dancers. All anatomical planes (axial, coronal, and sagittal) can be used in order to obtain
T2 values.

Penerapan strategi dan metode pembelajaran yang tepat sesuai dengan perkembangan jaman dan teknologi akan meningkatkan efektifitas pembelajaran mahasiswa dan dapat meningkatkan daya belajar mandiri mahasiswa, dengan metode Flipped Classroom model pembelajaran tradisional dibalik, yang biasanya materi diberikan di kelas dan mahasiswa mengerjakan tugas di rumah. Konsep Flipped Classroom mencakup active learning, keterlibatan mahasiswa, dan podcasting, materi terlebih dahulu diberikan melalui video pembelajaran yang harus ditonton mahasiswa di rumah. Sebaliknya, sesi belajar di kelas digunakan untuk diskusi kelompok, diskusi dengan dosen tentang materi yang sulit untuk dipahami pada saat belajar mandiri dan mengerjakan tugas. Setelah dilakukan evaluasi hasil pembelajaran Flipped Classroom didapatkan hasil sebanyak 69,2% media sosial menjadi bagian penting dalam pembelajaran, 76,9% mahasiswa lebih menyukai pembelajaran dalam bentuk video dibanding dengan model tradisional, 84,6% mengiyakan model pembelajaran ini dapat meningkatkan keinginan belajar mandiri mahasiswa, 89,2% belajar dengan menggunakan metode ini memberi manfaat untuk pendidikan masa depan, 69,2% model pembelajaran ini memberikan banyak waktu mahasiswa untuk melakukan kegiatan di laboratorium, 57,1% mahasiswa dengan menggunakan metode ini memberikan kesempatan lebih besar komunikasi atau interaksi dengan mahasiswa yang lainnya dan sebesar 64,3 % mahasiswa ternyata lebih termotivasi belajar menggunakan metode Flipped Classroom

Published: December 2020

This article deals with the approximate algorithm for two dimensional multi-space fractional bioheat equations (M-SFBHE). The application of the collection method will be expanding for presenting a numerical technique for solving M-SFBHE based on “shifted Jacobi-Gauss-Labatto polynomials” (SJ-GL-Ps) in the matrix form. The Caputo formula has been utilized to approximate the fractional derivative and to demonstrate its usefulness and accuracy, the proposed methodology was applied in two examples. The numerical results revealed that the used approach is very effective and gives high accuracy and good convergence.

Published: November 2020

An exponential increase in liver disease is driving a critical shortage of donor livers for patient transplant. In the UK alone, 58 people died in 2019 while waiting for a donor organ. A solution is sought in the form of tissue-engineered devices which support the survival and function of primary human hepatocytes. Previous work has shown that biofunctionalization of electrospun scaffolds influences hepatocytes. This study assesses the impact of drug-derived ECM on primary human hepatocytes (PHHs); a gold standard research resource. Hepatocytes seeded onto electrospun PLA scaffolds were subjected to drug treatment using histone deacetylase inhibitors. These cells were stripped from the scaffolds to leave behind their ECM. The resulting ECM-PLA scaffolds were seeded with PHHs and cultured for 24/72/120 hours. Scanning electron microscopy (SEM), mechanical and biochemical quantification, histology, and gene expression analyses were performed on the scaffolds. Results demonstrate PHHs are significantly influenced by the drug derived ECM:PLA scaffolds, with alterations in albumin production and gene expression demonstrated. Creating multidimensional scaffolds like these provides a method of creating tailored environments for liver bioengineering and the investigation of cell matrix interactions and is a step on the path to providing lab grown organoids for patient transplant.

Behavioural toxicity is a very applicable area in the vast field of ecotoxicology where,assessment of the alteration of behaviour is an effective tool to evaluate neural activity in an organism. In our present study, we have shown that arsenic trioxide exposure can stimulate repetitive grooming activity in a freshwater prawn, Macrobrachium lamarrei; however, over time the organism can modulate the grooming performances to less. We predict that repetition in the grooming behaviour is a case of neurotoxicity by arsenic and induction of Autism Spectrum Disorder (ASD) within a short period of exposure time.

Published: December 2020

Background: The Total Worker Health program represents a holistic approach to advancing worker well-being that combines occupational safety and health practices with other workplace policies and programs that are not traditionally linked. Total Worker Health requires new types of interdisciplinary collaboration and programmatic coordination. Pre-implementation assessment is thus important to plan for successful organizational “fit” when the program is introduced. This study prospectively identified potential implementation facilitators and barriers among five public healthcare facilities that had already agreed to participate in a study to implement and evaluate the Healthy Workplace Participatory Program.Methods: A mixed methods baseline assessment comprised an online survey and follow-up interviews. Key organizational and labor leaders were asked to identify resources and skills available for successful program implementation; potential barriers inside or outside the organization; and key performance indicators. Findings were presented to implementation stakeholders in study sites and used for planning how to tailor implementation to fit the organizational context and to provide the resources needed for success. Results: Potential facilitators included leaders’ willingness and commitment to develop interventions addressing a broad range of occupational safety and well-being health priorities (consistent with Total Worker Health); existing staff expertise in occupational safety and health; favorable attitudes regarding expected program outcomes; and positive alignment between the program and organizational mission and values. Potential implementation barriers included limited staff time to attend meetings, limited resources to support locally designed interventions, and poor management communication systems. Examples of tailoring strategies included extending time and effort to recruit leaders and workers while gaining their trust and securing program resources; developing sample program communication templates to strength health and safety communication efforts; and providing detailed training around issue selection procedures, communication, local intervention development, and change management. Conclusions: The prospective identification of potential facilitators and barriers represents a useful strategy for tailoring the implementation of a participatory, Total Worker Health program.
