Authors: You Huay Woon , Chong Michael Khoo Boon , Lin Chong Zhi , Lin Teoh Wei
Published: April 2020

The performance of a control chart is commonly investigated based on the assumption of known process parameters. Nevertheless, in most manufacturing and service applications, the process parameters are usually unknown to practitioners. Hence, they are estimated from an in-control Phase-I samples. As such, the performance of the control chart with estimated process parameters will behave differently from the corresponding chart with known process parameters. To study this issue, the exponentially weighted moving average (EWMA) median chart is examined in this article. The EWMA median chart is traditionally investigated based on the average run length (ARL). The limitation of the ARL is that it requires practitioners to specify the shift size in advance. This phenomenon is not ideal for practitioners who do not have background knowledge of the process. In view of this, the EWMA median chart with known and estimated process parameters is studied based on the ARL and expected average run length (EARL). The results indicate that as long as the particular shift size is within the range of shifts, the performance of the chart is almost the same, for the EWMA median chart with known and estimated process parameters.

Authors: Mohsin Saeed Noora , Elfaki Faiz Ahmed Mohamed
Published: April 2020

The term survival analysis has been used in a broad sense to describe collection of statistical procedures for data analysis for which the outcome variable of interest is time until an event occurs, the time to failure of an experimental unit might be censored and this can be right, left, interval, and Partly Interval Censored data (PIC). In this paper, the analysis of this model is conducted based on parametric Weibull model via PIC data. Moreover, two imputation techniques are used, which are: left point and right point. The effectiveness of the proposed model is tested through numerical analysis on simulated and secondary data sets.
Wavelet as a Viable Alternative for Time Series Forecasting
Authors: Lee Heng Yew , Beh Woan Lin , Lem Kong Hoong
Published: April 2020

Analysis of financial data is always challenging due to the non-linear and non-stationary characteristics of the time series which is further complicated by volatility clustering effect and sudden changes such as jump, steep slopes and valleys. Classical regression based analysis techniques often entail rigorous mathematical treatments albeit with little success in exploiting the differing frequency characteristics to uncover hidden but valuable trending information. Wavelet, on the other hand provides an efficient way to represent time series with such complex dynamics by decomposing it into time-frequency space and at the same time preserve both temporal and spectral information. This property enables analysts to identify the dominant modes (spectral information) of a time series and observe how those modes vary over time (temporal information). Most importantly, wavelet transform is computationally efficient, only a small number of wavelet coefficients are needed to describe complicated signals. This paper seeks to establish cases for the use of wavelets as viable tools in time series forecasting. Two time series, Kijang Emas Daily Index and Bit Coin Daily Price with differing characteristics are used as subjects of study. Out-of-sample dynamic forecasting of 20 points is made using best-fit ARIMA and prior-point imitation follow by wavelet de-noising methods (imitate-wavelet). Comparisons made with MAPE measurements of ARIMA and imitate-wavelet methods indicated comparable forecasting performance between the simpler imitate-wavelet techniques and ARIMA model.

This research focuses on assessing the goodness of fit for the Gompertz model in the presence of right and interval censored data with covariate. The performance of the maximum likelihood estimates was evaluated via a simulation study at various censoring proportions and sample sizes. The conclusions were drawn based on the results of bias, standard error and root mean square error at different settings. Following that, another simulation study was carried out to compare the performance of the proposed modifications to the Cox-Snell residuals for both censored and uncensored observations at different combinations of sample sizes and censoring levels. The results show that standard error and root mean square error values of the parameter estimates increase with the increase in censoring proportions and decrease in the number of sample size. This indicates that the estimates perform better when sample sizes are larger and censoring proportions are lower. The performance of the proposed modifications of the Cox-Snell residuals showed that they perform slightly better than existing method.

In neurobiological studies, crucial is the selection of most appropriate and informative experimental methods, one of which is immunohistochemistry. This review briefly summarizes the experience of adaptation of immunohistochemical methods to nervous system studies accumulated over years the Laboratory of Functional Morphology of the Central and Peripheral Nervous System (Institute of Experimental Medicine). The aim of this work was to determine the most effective and reliable immunomarkers for neurobiological studies. The article contains theoretical basis and practical recommendations for use of key cytospecific and functional markers used in studies of structural and functional organization of brain and spinal cord of mammalian animals and human. In particular, the results of immunohistochemical reactions to neural markers (NeuN, neurofilament proteins, alpha-tubulin, alpha-synuclein), neurotransmitter synthesizing enzymes (tyrosine hydroxylase, glutamate decarboxylase, choline acetyltransferase, NO synthase) and glial markers (GFAP, glutamine synthetase, Iba-1, vimentin) are demonstrated. The presented methodology is useful for experimental neurobiology and clinical morphological diagnostics.
Molecular diagnostics in oncology: new trends
Authors: Imyanitov Evgeny N.
Published: April 2020

Molecular diagnostics is a mandatory component of modern clinical oncology. The most known examples of molecular diagnostic procedures include the detection of hereditary cancer syndromes and the analysis of somatic drug-sensitizing mutations in protein kinases. Advances in cancer research as well as the development of new technologies led to emergence of new trends in this area of medicine. The invention of next generation sequencing (NGS) has a potential to dramatically change the landscape of molecular diagnostics. NGS allows to significantly improve the efficiency and availability of genetic testing for hereditary cancers as well as to undertake comprehensive tumor mutation profiling to guide the therapy choice. Tumors usually change their properties during therapeutic intervention. Monitoring of these properties is important for proper selection of further treatment options. So-called liquid biopsy is essential for this purpose, as it allows to detect key molecular features of the tumors by a non-invasive approach. There is an increasing popularity of ex vivo tumor models, which allow to cultivate tumor cells and to select the therapy based on the results of drug sensitivity tests.

Published: April 2020

Purpose— to perform a comparative analysis of the clinical efficacy of intrastromal keratoplasty (ISKP) in patients with keratoconus during surgery with and without Verion digital marking device.

Patients and methods. 37 patients (50 eyes) with corneal astigmatism up to -5.0 diopters were included in the study. These patients were operated with the femtolaser method of ISKP with implantation of corneal segments. The average age of the patients was 27.96 ± 3.40 years. The observation period is from 3 to 12 months. All patients were divided into two groups depending on the surgical technique: Verion-assisted, using a digital marking device and taking into account the angle of cyclotorsia, or standard, without taking into account the angle of cyclotorsia. The first main group included 28 eyes (56 %), the second control group included 22 eyes (44 %) accordingly.

Results. The functional results after ISKP in both groups were quite good. Stabilization of functional parameters and keratometric data was noted in the postoperative period, by 3 months. Patients of the main group showed a statistically significant (p < 0.05) increase in average uncorrected visual acuity to 0.50 ± 0.16, and visual acuity with maximum correction to 0.70 ± 0.12 (p < 0.05). The average keratometry of the weak meridian decreased to 44.3 ± 1.4 diopters, the average keratometry of the strong meridian decreased to 50.8 ± 3.2 diopters. Patients in the control group showed a statistically significant (p < 0.05) increase in average uncorrected visual acuity to 0.45 ± 0.12, and visual acuity with maximum correction to 0.60 ± 0.17. The average values of keratometry of the weak meridian decreased to 45.3 ± 1.8 diopters, the average values of keratometry of the strong meridian decreased to 51.8 ± 2.2 diopters. The results of the vector analysis reliably indicate a significantly higher accuracy of the Verion-assisted ISKP. Which is confirmed by the achieved indicators of the “success” index, the calculated astigmatism vector close to the actual postoperative astigmatism vector, the smaller the magnitude of the astigmatism axis difference vector compared to the control.

Conclusion. The use of the Verion-assisted intrastromal technique for keratoconus reduces the risk of erroneous positioning of the corneal segments in the tunnel during transferring diagnostic data to the operating room. Taking into account the angle of cyclotorsia during cutting into the intrastromal tunnel increases the effective correction of the cylindrical component of refraction, which is confirmed by the main coefficients of the vector analysis by N. Alpins.

Authors: Kamenskikh T. G. , Kolbenev I. O. , Melnikova Y. A. , Andreychenko O. A.
Published: April 2020

Micro incision vitrectomy surgery with removal of epiretinal and internal limiting membranes is used for treating various forms of vitreomacular traction syndrome.

Objective: to study the condition of retinal microcirculation using the OCTA method in the patients with traction maculopathy and macular ruptures before and after vitrectomy.

Patients and Methods. The study included 160 patients, of which 55 had epiretinal fibrosis (Treatment 1), 60 had macular ruptures (Treatment 2), and 45 with no ophthalmic pathology (Control). Treatment 2 group included two subgroups: 2a — patients with large-diameter ruptures (over 800 μm) subject to inverted internal limiting membrane flap technique (n = 12), and 2b — patients with 430–800 μm ruptures subject to rapprochement of the rupture edges with a platelet mass technique. All patients underwent conventional ophthalmology examinations and optical coherence tomography angiography (OCTA) using Sirrus HD-OCT 5000, Carl Zeiss, Germany.

Results. In the postoperative period, there was an improvement in retinal microcirculation in the Treatment 1 patients, and the values of both perfusion and vascular densities increased. A month later, an additional improvement of these indicators was recorded against the background of a decrease in retinal thickness and restoration of the vitreoretinal interface configuration. In the early postoperative period, Treatment 2 patients showed significant difference in the capillary density of the superficial vascular complex from the control group. A month later, the density of blood vessels in the Treatment 2 patients achieved control group values. Despite an immediate increase in perfusion measurements after surgical treatment, their values in a month were still lower than in the control group.

Conclusions. In the patients with epiretinal membrane and macular ruptures, a statistically significant decrease in both vascular and perfusion densities of the surface capillary complex was revealed by OCTA. The effects of vitreoretinal surgery performed on Treatment 1 and 2 patients with macula traction pathology included increased visual acuity, decreased retinal thickness, and restoration of the proper vitreoretinal profile. Based on OCTA results, we discovered a gradual increase in vascular density of the macula in Treatment 1 and 2 patients after surgical treatment of VMT syndrome. Retinal perfusion in the macular region of Treatment 1 patients achieved the values of the control group within a month, while in Treatment 2 patients they increased, but remained lower than in control group. OCTA is a highly informative method for the diagnostics and monitoring of the eye posterior segment condition in the patients with VMT syndrome.

Published: April 2020

Purpose: to study the effect of dosed pneumatic vasocompression (DPVK) on the functional parameters of the organ of vision in patients with primary open-angle gluacoma in the complex therapy of this form of pathology.

Patients and Methods. The study included 39 patients with stage II POAG, which were randomized into two groups: main and control. All patients received a conservative complex drug therapy. Patients of the main group were additionally conducted DPVK sessions — twice a week (only 4 procedures during the entire course of treatment). All patients underwent standard ophthalmologic examination, hemostasis and fibrinolysis.

Results. In the main group of patients, 1 hour after the end of compression, an increase (from baseline) in t-PA level (by median — 1.4 times) was observed while reducing the content of PAI-1 (by median — 2.7 times); improvement of hydrodynamic indicators (improvement of the outflow lightness coefficient, by 19.04 % in OD and 20.0 % in OS, decrease in KB by 24.7 % in OD and by 22.3 % in OS from the initial level) and retinal sensitivity (decrease the number of cattle type 1 in both eyes: 1.70 times on OD and 2.14 times on OS, decrease in type 2 cattle by 2.70 (OD) and 2.30 times (OS). In this regard, an increase sites of normal retina’s photosensitivity in 1.14 times on the OD and 1.19 times on the OS, in contrast to patients in the control group, where no significant changes were found.

Conclusion. The obtained preliminary results of the study indicate the prospects for non-pharmacological stimulation of fibrinolysis in the inpatient stage of the addition of conservative therapy in patients with POAG, achieved with a course of dosed pneumatic vasocompression.

Konsep Distribusi Muhammad Baqir al-Sadr dan Perbandingannya Dengan Teori Keadilan Distribusi Kontemporer
Authors: Furqani Hafas , Hamid Abdul
Published: April 2020

Abstract This study aims to examine the concept of distributive justice according to Muhammad Baqir al-Sadr and comparing it with the conventional theory of distributive justice. Al-Sadr’s concept of distributive justice is explored from his magnum opus, Iqtisaduna, in which he criticizes the Capitalist and Socialist economic system and put forward his thought on Islamic economic system. This research is a qualitative study using content analysis. The approach used is a comparative analysis with contemporary distribution justice concepts and theories. This study found that in al-Sadr’s conception, distribution should be put earlier than production in an economic system. Distribution is classified into pre-production distribution and post-production distribution. To realize distributive justice, al-Sadr also argues the importance of property ownership rights and compensation. He also argues that the state plays an important role in regulating the economy and establishing distributive justice. AbstrakPenelitian ini bertujuan untuk mengkaji konsep keadilan distribusi menurut Muhammad Baqir al-Sadr dan perbandingannya dengan teori keadilan distribusi kontemporer. Konsep keadilan distribusi al-Sadr digali dari magnum opusnya Iqtisaduna yang berisi kritikan kepada sistem ekonomi Kapitalisme dan Sosialisme serta kontribusi pemikiran beliau dalam membangun ekonomi Islam. Penelitan ini adalah penelitian kualitatif menggunakan analisa konten analisis. Pendekatan yang digunakan adalah analisa komparasi dengan konsep dan teori keadilan distribusi kontemporer. Hasil penelitian ini menemukan bahwa dalam pemikiran al-Sadr, distribusi menduduki posisi lebih awal daripada produksi. Ia melihat permasalahan ekonomi itu muncul pada ketidakmerataan distribusi, bukan pada produksi. Oleh karena itu, al-Sadr mengklasifikasikan distribusi kepada dua tahap, distribusi pra-produksi dan distribusi pasca-produksi. Untuk mewujudkan keadilan distribusi, menurut al-Sadr sangat penting memperhatikan hak kepemilikan dan kompensasi. Al-Sadr juga berpandangan bahwa negara berperan penting sebagai pilar utama dalam pengaturan ekonomi dan penegakan keadilan distribusi.

Published: April 2020

Abstract This study aims to determine the relationship between Nazhir's knowledge and attitude in the Krian District of Sidoarjo Regency with their behavior in the registration of waqf land. This research was conducted with an associative descriptive approach where the data obtained from the questionnaire in the form of numbers. The number of samples used in this study amounted to 80 respondents who are managers of land waqf in Krian District, Sidoarjo Regency and use simple random sampling techniques. This study uses a questionnaire with a Likert scale. The results of this study indicate that Nazhir's knowledge and attitude related to the procedure for registering waqf land has a moderate and significant correlation with Nazhir's behavior in carrying out the act of registering waqf land. That is due to the lack of socialization from authorized institutions to the community to manage the administration of waqf land. The knowledge and attitude possessed by Nazhir regarding the registration of waqf land would increase Nazhir's behavior or actions in registering the waqf land. This research was conducted to prevent future disputes caused by the absence of written evidence as waqf land.AbstrakPenelitian ini bertujuan untuk mengetahui hubungan pengetahuan dan sikap Nazhir di Kecamatan Krian Kabupaten Sidoarjo dengan perilaku mereka dalam pendaftaran tanah wakaf. Penelitian ini dilakukan dengan pendekatan deskriptif asosiatif dimana data yang diperoleh dari kuisioner berupa angka. Jumlah sampel yang digunakan pada penelitian ini berjumlah 80 responden yang merupakan pengelola wakaf tanah di Kecamatan Krian Kabupaten Sidoarjo dan menggunakan teknik simple random sampling. Penelitian ini menggunakan kuisioner dengan skala likert. Hasil penelitian ini menunjukkan bahwa pengetahuan dan sikap Nazhir terkait tata cara pendaftaran tanah wakaf memiliki korelasi sedang dan signifikan dengan perilaku Nazhir dalam melakukan tindakan pendaftaran tanah wakaf. Hal itu dikarenakan kurangnya sosialisasi dari lembaga yang berwenang kepada masyarakat untuk mengelola administrasi tanah wakaf. Adanya  pengetahuan serta sikap yang dimiliki Nazhir terkait pendaftaran tanah wakaf akan meningkatkan perilaku atau tindakan Nazhir dalam mendaftarkan tanah wakaf. Penelitian ini dilakukan untuk mencegah adanya persengketaan yang terjadi dikemudian hari yang disebabkan karena tidak adanya bukti tertulis sebagai tanah wakaf.

Introduction: With regard to high prevalence of musculoskeletal disorders in the construction industry workers, the aim of this study was to investigate the prevalence of musculoskeletal disorders and their relevant risk factors in workers of a construction factory.
Methods: This descriptive-analytical cross-sectional study was conducted in 2019. In this regard, 150 workers were selected from a construction factory located in Tehran City, Iran. The census sampling method was applied in the area under study. The data gathering tool were Cornell questionnaire and WERA ergonomic risk assessment method. The questionnaires were completed while the workers' postures were assessed in their work stations. Data were analyzed applying suitable descriptive and analytical tests in SPSS software version 22.
Results: The analysis of questionnaires showed that the workers' lower back had the highest average score of pain. The wrist, knee, and shoulder had the highest pain average scores, respectively. The result of ergonomic assessment by WERA method indicated that the lower back had the highest risk score. Similarly, WERA assessment score was significantly related to the type of job (p-value < 0.001). Among the understudy occupations, masonry, concrete testing, and welding had the highest risk scores, respectively.
Conclusion: The most ergonomic risk factors in activities of the extensive occupational groups are associated with multiple occupational tasks that endanger workers for serious risk factors in the lumbar and knee areas. Therefore, implementation of ergonomic interventions is necessary for improving the working conditions of construction occupations.

Introduction: Bullying is a kind of low-level violence that has recently attracted the attention of researchers and psychologists in the field. The purpose of this study was to investigate the modeling of structural relationships between Alexithymia and bullying with the role of mediator of students' adaptationin             students.M ethods: Correlational research based on structural equation modeling technique, in particular regression equations (combining path analysis and factor analysis Second level). The statistical population consisted of all female students of the Humanities Department of Payame Noor University of Sari in the academic year of 2018-19. In this research, 401 students were selected as a sample by multistage cluster random sampling. Data gathering tools were Patchin and Hendowjah's Bullying Questionnaire (2011), Emergency Neural Network (1994), Baker and Siriac compatibility (1984).
Resulth: The findings showed that the research model was confirmed and in general, 36 percent of students' bullying could be explained by student Alexithymia and student adaptation. Also, Alexithymia and student adaptation variables have a direct direct effect on students 'bullying. Emotional neural pathology has an indirect effect on students' bullying, with regard to student interpersonal mediation.
Conclusion: The results of this study emphasized the importance of Alexithymia with regard to the quality of student compatibility., which can provide practical implications for reducing the level of bullying to counselors and psychologists, and considering the findings of the study can be used to reduce the incidence rate. Bullying among students has led to increased levels of academic compatibility as well as identification and correction of students' Alexithymia.
Disordered Eating Patterns and Sexual Self-Esteem in Married Women: The Mediating Role of Body Image Concern
Authors: Shameli Leila , Davodi Maryam
Published: April 2020

Introduction: The contemporary psychology is looking for numerous mediators and risk factors that may exacerbate the marital relationship with regard to the consequences of disordered eating patterns in general and sexual satisfaction in particular. The purpose of this study was to investigate the mediating role of body image concern in the relationship between disordered eating patterns and sexual self-esteem in married women.
Methods: The participants of this study were 213 married women who referred to the nutrition department of Kazerun City in 2019 and were selected by available sampling method. To collect data, Eating Attitudes Test (Garner & Garfinkel, 1979), Body Image Concern Inventory (Littleton et al., 2005), and Sexual Self-Esteem Inventory for Women (Zeanah, Schwarz, 1996) were used.
Results: The results of structural equation modeling indicated that the three subscales of disordered eating patterns were directly associated with sexual self-esteem. Of the above-mentioned patterns, only the "overeating and food preoccupation" pattern affected sexual self-esteem indirectly by mediating of body image concern (β= -0.14, P< 0.01). Therefore, it can be argued that overeating and food preoccupation reduced the sexual self-esteem in married women by increasing the body image concern.  
Conclusion: Overall, the results of this study indicated the importance of simultaneous attention to disordered diets and body image concern for predicting sexual self-esteem in married women.

Introduction: The present study was aimed at describing the epidemiological characteristics of female breast cancer and explore its main risk factors in Sulaymaniyah city, the Kurdistan region of Iraq.Material and Methods: The present case-control study was conducted in Sulaymaniyah, the Kurdistan region of Iraq from 2012-2014 in two hospitals. The study sample consisted of 150 women with breast cancer and 150 healthy women. Required data including sociodemographic and lifestyle factors, medical history, and reproductive factors were collected using a questionnaire through face-to-face interviews.Results: The mean age of the cases and controls was 47.89±10.98 and 47.38±10.87 years respectively. Low level of education was a risk factor for breast cancer, such that breast cancer was significantly less prevalent among women with university education than those with lower education (P=0.001). The likelihood of developing breast cancer in women with a positive family history of cancer was significantly higher (P=0.003). Also, women with rural residency, unemployment, low income, early age of menopause, multigravida (+3), history of abortion, duration of feeding the first and second babies, and obesity were at a significantly higher risk of developing breast cancer (P<0.05).Conclusion: The Kurdish women in Iraq, develop breast cancer at age range of 40-50 years. Women with low level of education, a positive family history of cancer, rural residency, unemployment, low income, multigravida (+3), history of abortion, and obesity need to be taken into special consideration in order to diagnose breast cancer early and adopt appropriate interventions.

The problem is the low ability of students, and the low orientation of developing students' thinking skills in learning, especially the thinking skills metacognition which is the thinking of the 21st century skills. These factors are one of the main factors that are still oriented towards achieving knowledge in a partial-textual way and not an integrative contextual understanding of the knowledge learned. Therefore, there are efforts that can be used to resolve the problem through effective and up-to-date effective models that are effort-oriented in improving students' metacognitive thinking skills, which is through the application of critical literacy models based on project based learning approaches. The critical multiliteration model is a learning model developed based on awareness and recognition of cultural perspectives and the diversity of learning styles. In addition, the critical multiliteration model is a model that is oriented towards efforts to build students' thinking skills through multicontext, multicultural and multimedia approaches. In this context, critical multiliteration models are specifically developed as a dynamic learning approach, where students actively explore problems in real world, provide challenges, and gain deeper knowledge. This is based on the purpose of developing a model oriented to the development of metacognitive thinking skills.
