Background: Glaucoma is a progressive optic neuropathy that is significantly related to Ocular Surface Disease. The ocular surface includes the cornea, conjunctiva, eyelids, and lacrimal glands; hence the ocular surface disease directs damage to the surface layers of the eye. Methods: This study is a cross-sectional study, conducted in Anwer khan Modern Medical College Hospital, Dhaka, at the Department of Ophthalmology. The study was conducted during the period from December 2020- to November 2021. The sample size was 121. Result: In the age group51-61, there were highest participation 33(27.3%) and among the participants males were 62 (51.2%) and females were 59(48.8%). Mean time for glaucoma or ocular hypertension diagnosis(years) was 8.11±7.42. Open-angle glaucoma was most frequent, 97(95.1%). Mean IOP assessment- Right eye(mmHg) was 15.87±3.97 and Men IOP assessment - Left eye(mmHg) was 15.84±3.94. Conjunctival hyperemia was controlled in 13(10.8%), mild in 49(40.8%), moderate in 27(22.5%), and severe in 32(26.7%) cases which was quite high. When the OSD grade was severe in (˃12 dB) 37(30.6%), the glaucoma stage was also severe (˃12 dB) in 27(22.3%) cases. Conclusion: Glaucoma had affected millions of patients around the world and chronic use of topical glaucoma medications may negatively impact the patient’s ocular surface. There is a strong association between OSD and quality of life in medically treated glaucoma patients.

Published: April 2022

Onchocerciasis is a devastating tropical disease that makes 18 million people suffer in Africa, the Arabian peninsula and Latin America. It is a filariosis characterized by dermatological, ocular and systemic manifestations and is due to infection by a nematode of the genus Onchocerca volvulus, transmitted by the SIMULIA sting. Parasites live in subcutaneous tissue or tangled in fibrous nodules: onchocercomas. This filariasis is rightly feared for its ocular location that can cause blindness. The specific diagnosis is based on the detection of microfiliars by exsangue biopsy. The mass treatment of populations exposed by ivermectin has resulted in a significant decline in onchocerquian endemicity and global complications over the past decade. We report a case of a young woman of 20 years of Cameroonian origin who consulted for pruritic annular lesions of the legs and torso and in whom the examination found a nodule under mammary which was surgically excised and whose pathological examination has objectified the presence of multiple microfiliars within granulomas.

Published: April 2022

Alcoholic cardiomyopathy (ACM) is a condition caused by excessive alcohol consumption, which causes a reduction in cardiac function and disturbance in heart pumping ability. Clinical manifestation ranges widely, from asymptomatic to acute fulminant heart failure, depending on the degree of deterioration of heart function. This is a case report of a 37-year-old man who presented to the emergency room, he was referred with the diagnosis of alcoholic cardiomyopathy. From echocardiography, we found reduced left ventricular function with ejection fraction Teich 41,8%, and left ventricular segmental analysis show global hypokinetic with eccentric left ventricular hypertrophy (LVH) which leads to diagnosis cardiomyopathy. Diagnosis of ACM is by exclusion. There is a two-step diagnosis process beginning with cardiac imaging and the second step involves laboratory tests To determining about the etiology of cardiomyophaty, we should depend on patient’s history. The diagnosis of alcoholic cardiomyopathy is based on structured history related to alcohol abuse in the long period. Obtaining information about history of alcohol abuse is challange in a non-alcoholic culture and environment. It dipending on the ability of the physicians to explore in-depth information concerning personal problem. Good anamnesis and another supporting examination can help the physicians to making differential diagnosis and makes the right treatment plan for the patient.

EVIDENCE-BASED TEACHING STRATEGY
Authors: Rommel Pascual Manzon
Published: April 2022

Most teachers care about their students results, and if you are reading this article, you are undoubtedly one of them. Be supported by hard research, instead of anecdotal case studies or untested theories. Have a substantially higher effect on student results than other teaching strategies. Be able to be used on a wide range of subjects and at every year level.
What evidence-based teaching strategies made it onto the list? Research shows that evidence-based teaching strategies are likely to have the largest impact on student results performance. Research shows that a few of these teaching strategies, such as holding high expectations of students, have a significant positive impact on student results.
Do not assume that a teaching strategy is no good just because it is not in the top 10 or commonly used by teachers. That said, some popular teaching strategies do not have a large effect on student results. Once you are clear about what you want your students to know and be able to do by the end of the lesson, you need to tell them what they need to know and show them how to do the tasks you want them to be able to do.
Some evidence-based teaching strategies that did not make the top 10 or are commonly used by teachers are still worth adopting. However, when you explore the thousands of research studies on the topic, it is apparent that some teaching strategies have far more impact than other teaching strategies do.

Authors: Gómez Santiago Marlen , Cholico-González Diana , Ortiz Lara Noemi , Escudero García Ramiro
Published: April 2022

El procesamiento de minerales refractarios por métodos convencionales resulta en recuperaciones pobres de oro, siendo una causa el efecto preg-robbing al presentarse la adsorción del complejo Au(CN)2- en la superficie de materia carbonácea durante la lixiviación. Se hace necesario entonces caracterizar mineralógicamente e identificar la materia carbonácea para establecer la complejidad del mineral. Posteriormente se debe evaluar el grado del preg-robbing para diseñar el procesamiento y recuperar el máximo del metal precioso atrapado. Así, un mineral carbonáceo se caracterizó mediante DRX y por espectroscopía infrarroja, además de evaluar la capacidad de adsorción de Au(CN)2- del mineral. Por DRX, se identificaron las especies calcita y cuarzo; por espectroscopía infrarroja, las bandas características de Ca-O, C-O, Si-O y la C=C asociada a materia carbonácea; de la capacidad de adsorción se determinó un valor q=0.198 mg Au(CN)2-/gmineral, que corresponde al 70% de Au(CN)2- adsorbido, por lo que el mineral se clasifica como preg-robbing.

Published: April 2022

Currently, Islamic moderation (wasathiyyah) is emphasized as the mainstream of Islam in Indonesia. This mainstreaming idea is the answer to the emergence of various problems in the name of religion. The difference in diversity in Indonesia, including in terms of religion, is something that cannot be denied. Therefore, tolerance in the midst of differences that exist in society is an important thing to understand and do together. Education in schools is one means of instilling the values of religious moderation in students. Not only in classroom learning, but this moderation value can also be instilled through extracurricular activities. Rohis is extracurricular that focuses on religious development. This study uses a library research approach. The results show that values in religious moderation can be instilled through various activities in extracurricular Rohis. The coaches and mentors of the Rohis need to plan for the activities of the Rohis by inserting the values of religious moderation. As well as providing special assistance to students so that they have a deep understanding related to religious moderation.

Influence of Co-Curricular Activities Provided in a School on Students Level of Self-Esteem: Case of Public Secondary Schools in Nyandarua West Sub-County, Kenya
Authors: Muchemi Peter , Kiumi John Kanjogu
Published: April 2022

The major purpose of the study was to investigate whether students’ level of self-esteem can be influenced by co-curricular activities provided in a school. To achieve this objective, co-curricular activities provided in a school and students’ self-esteem were measured and the data obtained was analysed. The aim was to find out whether the selected school factor had any influence on students’ level of self-esteem. The research was conducted using ex post facto research design. Co-curricular activities provided in a school was seen as a naturally occurring independent variable, which could influence students’ level of self-esteem. The population of the study comprised of students in public secondary schools in Nyandarua West Sub County. The Sub County had 8 public secondary schools when the research was conducted; with a student population of 3067. Data relevant to the study was collected using questionnaires prepared by the researcher. The questionnaires were administered to a sample of 240 students, selected using simple random sampling from the 1320 form two students in the Sub County. The data was analysed using mean calculations, percentages, and one-way ANOVA test. It was found out that co-curricular facilities available in a school had a significant influence on students’ self-esteem. Students in schools with more and better quality co-curricular facilities had a higher level of self-esteem than their age mates in other categories of schools which were rated lower in co curriculum facilities. Probably, schools with better facilities offered the students a chance of trying out their abilities and excelling in some. This success may have led to social success, a higher status among peers, popularity and even a career in future. This can translate to an improved self-esteem. However, in day schools where co-curricular facilities were rated as unsatisfactory students recorded a low level of self-esteem. It is therefore recommended that MOEST should finance seminars to sensitize secondary school administrators on adolescents’ co-curricular activities need, so that every Principal would endeavour to provide students with age-appropriate activities. The government can also exempt equipment for such purposes from tax, or otherwise supply these facilities to schools that do not have them. Further studies should be conducted to find out whether similar results would be obtained in other Sub Counties in Kenya.

Arduino-based PID Control of Humidity in Closed Space by Pulse Width Modulation of AC Voltage
Authors: Nakamori Seiichi
Published: April 2022

My previous work explored a method for constant temperature proportional-integral-derivative (PID) control in a closed space using an Arduino. Similarly, this paper proposes a method of PID control to keep the humidity constant in a closed space using Arduino. PID control by a pulse width modulation (PWM) signal with Arduino is used to keep the humidity constant due to the heat generated by an incandescent light bulb to which an AC voltage of 100 (V) is applied. Here, the humidity is measured using the temperature/humidity sensor DHT11. Specifically, the target value of humidity is set to 30 (%), and the experimental results of P, PD, PI, and PID controls are compared from the points of quick response and stationary performance. As an evaluation of stationary performance, the mean-square value of 1,000 data of the deviation (target value – measured humidity) is calculated, and the PID control is found to be the preferred control.

Published: April 2022

In this work, the effects of the cavity aspect ratio (AR) on the flow of Al2O3-water nanofluid in a two-dimensional cavity subjected on its lower part to a constant and uniform temperature. The governing equations are discretized by the finite volume method based one point closure turbulence model. For nanofluid proprieties, Maxwell-Garnetts model (MG) and Brinkman models are used for the calculation respectively of the conductivity and viscosity of the nanofluid. The parameters of this study are the shape parameter of the cavity from 2 to 14, Reynolds number Re between 4.103 and 105 and volume fraction of the nanoparticles between 0 and φ=4%. The cavity aspect ratio effect on the flow structure and heat transfer was also examined. The results confirm that the flow structure and heat transfer are very sensitive to the cavity aspect ratio. The numerical results highlight the effect of the main parameters on the distribution of Nusselt number and friction coefficient.

In order to adapt and develop the methodological support developed in the EU, a scientific and methodological approach to assessing potential partnerships in the formation of regional smart specialisation strategies has been justified. It is proposed to perform a set of diagnostic and communication procedures to identify and assess the prospects for interregional cooperation for each project initiative at the participatory stage of the entrepreneurial discovery process. Measures to identify potential partnerships include the following: justification of the feasibility of partnership and integration into existing cluster-network structures; identification of possible partners and study of their potential and interests; assessment of the readiness of regional stakeholders for partnership; formation of partnership proposals for a specific smart priority. This additional stage will allow to determine the possibilities of resource-competent strengthening of regional priorities of smart specialisation by combining knowledge and assets with innovatively active European regions.
The proposed author’s scientific and methodological approach to assessing the potential of cluster-network partnership of Ukrainian regions and EU member states is based on the calculation of an integral indicator that takes into account the assessment of innovative cooperation of each region and its cluster-network activity in a specific thematic area of smart specialisation. The structure is shown and the content of calculation procedures for determining the integral indicator of the potential of cluster-network interaction of the region based on information and analytical data of European ratings and platforms is developed.
The scientific and methodological approach has been tested on the example of Chemicals thematic partnership. The definition of groups of indicators for assessing innovative cooperation and cluster-network activity of 13 regions of the European Union, which are part of this partnership, has been consistently disclosed. A rating of chemical regions was formed to assess the potential of cluster-network interaction.

Published: April 2022

In the article the main parameters of functioning of the natural gas market in Ukraine are analyzed in the context of ensuring competitive relations between economic entities on it. It is revealed that the sphere of natural monopoly includes the markets of transportation, storage and distribution of natural gas; it is reasonable to consider the natural gas supply market as potentially competitive, because the supply of natural gas is provided by many suppliers as for industrial consumers and for the population. JSC «Ukrgazvydobuvannia» and NJSC «Naftogaz of Ukraine» with all entities related to it by control relations occupy a monopoly (dominant) position on the natural gas sales market directly from the producer.
The trends of price changes in the retail natural gas market for household and non-household consumers have been investigated. The comparative analysis of domestic prices for natural gas and its delivery with the prices of European countries has been carried out, the structure of natural gas prices for households in Ukraine and EU countries is given.
The key aspects of the development of the national retail and wholesale gas market are highlighted. The level of concentration in the wholesale natural gas market has been investigated using the Herfindahl-Hirschman index. It has been revealed that the level of concentration of its various segments may vary from low, which certifies the existence of a competitive environment, to high, which is inherent in a monopoly. This market is still at the stage of formation, the level of competitiveness is significantly differentiated by different suppliers. It should be noted that most gas consumers were not prepared for the introduction of the natural gas market, they did not have sufficient information about the rights guaranteed by the state and the opportunities provided by legislation.
It has been found out that violations of competitive activity in the natural gas market are quite frequent and the main ones found by the Antimonopoly Committee of Ukraine have been considered.
The main factors influencing the development of the competitive environment in the domestic natural gas market are given and the main problems of its formation are identified.

A refugee from Lithuania, Aleksandra Kasuba (1923–2019) arrived in the U.S. in 1947 and built a successful career in the competitive, male-dominated post-World War II New York’s art world. Beginning with small ceramic tile artworks that evolved into multi-media mosaics, Kasuba’s artistic vision expanded to shaping architectural spaces. From 1953 to 1970, appearances in exhibitions organized by the Museum of Contemporary Craft introduced her art to American and international audiences. Her pivotal solo exhibition at an important New York gallery in 1966 led to complex collaborations with noted architects for projects in major U. S. cities. Her innovative monumental designs in marble, brick and granite were focal points of public buildings and spaces. This article examines her key commissions completed from 1970 to 1986 in Chicago, New York City, Rochester, N.Y., Buffalo, N.Y., and Washington, D.C.

PATH ANALYSIS ON ESCALATION OF COMMITMENT OF INVESTORS IN DIFFERENT PROJECT SCENARIOS OF PPPS
Authors: Luo Qi , Gao Ruolan , Liu Jicai , Li Yahui
Published: April 2022

In public-private partnerships (PPPs), escalation of commitment (EOC) of investors often occurs when receiving negative feedback, leading to a great waste of resources and not conducive to the sustainable development of PPPs. The degree of project completion and decision-making responsibilities of investors with different conscientiousness and neuroticism may affect subsequent resource allocation and further influence their escalation behaviour. Thus, through scenario simulation, this paper constructs path analysis to illustrate the formation mechanism of EOC by investors with diverse conscientiousness and neuroticism in different degrees of decision-making responsibilities and project completion, in which confidence in completing the projects may present a mediating effect. The empirical results show that completion degree and decision-making responsibilities both positively affect investors’ EOC and that the interaction is significant. The impact mechanism of conscientiousness and neuroticism on EOC varies in different project scenarios. Then, some targeted recommendations are proposed to curb EOC. The findings provide scientific evidence for governments to conduct effective governance of EOC in PPPs.
