Aging, Vulnerability and Managing Type 2 Diabetes During a Pandemic
Authors: McConatha Jasmin Tahmaseb 
Published: July 2020

Older men and women have been found to be more vulnerable to negative outcomes should they contract Covid19, particularly if they also have comorbid conditions such as type 2 diabetes. Cultural, racial, ethnic, and social class differences exist in vulnerability to Covid19 and in the prevalence of type 2 diabetes. In the United States, for example, diabetes rates for minority and immigrant populations are higher than for non-Hispanic whites. During the a social health crisis, it is helpful to explore the ways that illness management and associated vulnerability influences the ways that minority elders attempt to maintain and promote their well-being. This paper presents a case study example of an older immigrant woman, diagnosed with type 2 diabetes, and her struggle to manage her illness during a pandemic. The risk of developing diabetes in the United States is 3 to 1 and risks increase with age (American Diabetes Association, 2020). Almost 50 % of black women as well as Hispanic men and women will develop diabetes in their lifetime (CDC, 2019). Disparities such as these have their origin in intersecting risk factors such as health care and lifestyle factors such as tress, poverty, weight, diet, and exercise patterns. Being a member of an ethnic minority and being overweight are the two significant factors associated with the onset of type 2 diabetes. During the coronavirus epidemic, these same factors also increase the risk for infection and for greater complications, even death as a result of infection (Society for Women’s Health Research, 2020). This essay illustrates the increased vulnerability and challenges including loneliness facing older women with type 2 diabetes during pandemic isolation.

The decline in students’ academic performance in Economics as a course of study in the last decade is worrisome. This study therefore seeks to investigate influence of students’ attitude towards Economics as a course of study on academic performance in the University of Lagos.
The study adopted descriptive survey research design and made use of a sample of One hundred and twenty (120) undergraduate students randomly selected from Economics Education cohort, Faculty of Education, University of Lagos, Akoka. A self-developed questionnaire of 34 items was used to collect information from the students after its validity and reliability (r=0.68) were determined with the use of split half method. The data collected were analysed using Mean, Standard Deviation, and Simple Percentage while Chi-square, independent t-test and One-way Anova statistical tools were used to analyse three hypotheses at 0.05 level of significance using (SPSS) testing program. The study revealed that there is significance influence of students’ attitude towards economics as a course on academic performance. Both male and female students have almost the same attitude towards economics as a course. Also, the attitude of students towards economics as a course is the same at different academic levels. In the light of the study`s results, the researchers presented a number of recommendations and proposals the most important of which are: Ministry of education should organize orientation programmes against wrong attitude of undergraduate students towards economics as a course in order to improve their motivation and academic performance. Since gender does not affect the attitude of students towards economics as a course, teaching and learning of economics as a course should be done freely among the students of different sexes. Seminars and symposiums should be organized by university management for Economics department, Faculty of Education about the prospects of the course to motivate them towards academic excellence.

Published: July 2020

The objectives of the study are to investigate time orientation and goal orientation levels in light of some variables, and to identify the relationship between the two variables. The sample of the study consists of 698 male and female students studding at Yarmouk University. Zimbardo and Boyd (1999) Time Orientation Scale and Abu Ghazal et al., (2013) Goal Orientation Scale are used after assessing the validity and reliability for both scales. The results of the study showed that the past positive domain in time orientation ranked first, followed by future past negative, present hedonism, present fatalistic, respectively. The results also showed that the domain of mastery-approach in goal orientations ranked first, followed by performance-avoidance, and finally performance-approach. The results of the study indicated a statistically significant positive correlations between future time orientation and mastery- approach goal orientation, and between past negative time orientation and performance- avoidance goal orientation. There are statistically significant positive correlations between time orientation domains and goals orientations domains except a negative correlation between present fatalistic time orientation and mastery-approach goal orientation

Authors: Buenvinida Lerma P. , Tamayo Rea G. 
Published: July 2020

This study determined the relationship among the school heads’ leadership and attributes, teachers’ morale and implication to school performance. Respondents of the study were 68 school heads and 532 teachers from public elementary schools of the Division of Laguna. The Level of Teacher’s Morale in terms of Teacher Rapport with Principal scored as good; while in terms of Satisfaction with Teaching was found moderately satisfied. Further, the relationship between school head leadership and professional attributes and teacher’s Morale in terms of rapport and personal and professional attributes are evident using the Chi-Square Test of Independence. The correlation between Building High Performance Team scores and Teacher Morale in terms of rapport comes out to be highly significant. However, School Leadership in terms of Problem Solving and Coordinating with Others and Leading & Managing Changes were not significant. For Interpersonal Sensitivity of School Heads and Teacher Morale in terms of rapport, the correlation is significant at p<.05. There are significant relationships between leading and managing changes to cohort survival, interpersonal sensitivity and completion rate with p<.05; and relationship between Teacher’s Morale in terms of satisfaction to completion rate. School heads need to evaluate and monitor the training needs assessment to address teachers’ professional growth and assist in improvement of the school performance. A similar research can be conducted to determine the validity of the relationship between teacher’s morale and school performance and to verify the results of this study.
The Influences of Economic Diversification and the mediating Effect of Industrial Development on Economic Growth in Oman: A Conceptual Framework
Authors: Al Yahyai Nasr , Azalina Aza , Supian Kamisah 
Published: July 2020

Industry is at the heart of a government's plans to transform the economy from a resource-based economy to a value-added one. Economic diversification is vital to countries’ long-term economic growth, but many resource-rich countries remain heavily reliant on revenues generated by natural resources such as mineral or oil production. In Oman, the fall in price oil compelled the government to rethink about development and economic plans in order to improve the living conditions of the population. The main objective of economic diversification agenda is to increase the contribution of these sectors to the gross national product (GDP) of Oman, raise production and create more jobs for these sectors. New technologies will promote the achievement of inclusive, sustainable industrial development through its creation and absorption. New innovations allow businesses to bring new products into the market and improve production efficiency. In addition, industrial development generates new employment and profit incentives. More products and productivity of production also add to the growth of the economy. Industrial development at the same time leads to the manufacture and diffusion of emerging technology. Only by industrialization can economies, industries and businesses build and maintain the requisite technical transition capabilities. This paper presents a conceptual or research framework that identifies the mediating effect of industrial development in the relationship between economic diversification and economic growth in Oman. Two main factors are considered, i.e., the strategic drivers consisting of economic and non-economic variables, and industrial development initiatives. The paper concludes with the discussion on the formulations of hypothesis statements that describe the inter-relationships between the constructs in the conceptual framework. It is expected that the proposed framework can be further verified and tested by using empirical research work.
Information and Communication Technology skills for Effective Competence Based Curriculum Implementation in Kenya
Authors: Ndiritu Anne , Gatotoh Augustine 
Published: July 2020

The vision of education service delivery in Kenya is to have an internationally competitive quality education, training and research for sustainable development. More developed countries are associated with their great investment in human capital. They are also associated with development of ICT which has led to improved standards of living and good governance. This study was carried out on 395 pre-school teachers who were undertaking their in-service training in Kiambu County. The study sort to establish ICT whether the teachers engaged in ECD centers had any skills in ICT. This study further sort to establish whether there was integration of ICT in teaching and learning in selected preschools in Kenya. A researcher designed questionnaire was used in the study. A total of 60.83 % of the total population had no knowledge of ICT and therefore did not integrate ICT in their teaching and learning in the selected preschools. All the teachers expressed that the government had not sponsored them for ICT training and the little they had they had sponsored themselves. Grounded on these findings the study recommended that the government should be on the forefront to not only invest in ICT infrastructure but also in education of teachers in ICT. With the paradigm shift in the Kenya’s education curriculum this concern should be immediate. The government should take up the responsibility of ensuring that all teachers are exposed to ICT skills since these will change their interaction with the students who are quite ahead of their teachers in technology.
Robust Monetary Policy Under Uncertainty About the Lower Bound
Authors: Tillmann Peter 
Published: July 2020

Abstract
Central banks face uncertainty about the true location of the effective lower bound (ELB) on nominal interest rates. We model optimal discretionary monetary policy during a liquidity trap when the central bank designs policy that is robust with respect to the location of the ELB. If the central bank fears the worst-case location of the ELB, monetary conditions will be more expansionary in the period before the liquidity trap.
An efficient approach for the numerical solution of fifth-order KdV equations
Authors: Ahmad Hijaz , Khan Tufail A. , Yao Shao-Wen 
Published: July 2020

Abstract
The main aim of this article is to use a new and simple algorithm namely the modified variational iteration algorithm-II (MVIA-II) to obtain numerical solutions of different types of fifth-order Korteweg-de Vries (KdV) equations. In order to assess the precision, stability and accuracy of the solutions, five test problems are offered for different types of fifth-order KdV equations. Numerical results are compared with the Adomian decomposition method, Laplace decomposition method, modified Adomian decomposition method and the homotopy perturbation transform method, which reveals that the MVIA-II exceptionally productive, computationally attractive and has more accuracy than the others.
Automated segmentation of thick confocal microscopy 3D images for the measurement of white matter volumes in zebrafish brains

Published: July 2020

Abstract
Tissue clearing methods have boosted the microscopic observations of thick samples such as whole-mount mouse or zebrafish. Even with the best tissue clearing methods, specimens are not completely transparent and light attenuation increases with depth, reducing signal output and signal-to-noise ratio. In addition, since tissue clearing and microscopic acquisition techniques have become faster, automated image analysis is now an issue. In this context, mounting specimens at large scale often leads to imperfectly aligned or oriented samples, which makes relying on predefined, sample-independent parameters to correct signal attenuation impossible.
Here, we propose a sample-dependent method for contrast correction. It relies on segmenting the sample, and estimating sample depth isosurfaces that serve as reference for the correction. We segment the brain white matter of zebrafish larvae. We show that this correction allows a better stitching of opposite sides of each larva, in order to image the entire larva with a high signal-to-noise ratio throughout. We also show that our proposed contrast correction method makes it possible to better recognize the deep structures of the brain by comparing manual vs. automated segmentations. This is expected to improve image observations and analyses in high-content methods where signal loss in the samples is significant.
Glenohumeral Extension and the Dip: Considerations for the Strength and Conditioning Professional

Published: July 2020

ABSTRACT
A significant number of resistance training injuries occur at the shoulder complex. However, there is a lack of research identifying predictive variables, which may increase the risk of these injuries. Certain exercises, such as those requiring the apprehension position (glenohumeral abduction with external rotation), have been investigated and found to be associated with shoulder pain and injury. However, there are additional exercises or positions that may also be associated with increased injury risk. The position of end-range glenohumeral extension, particularly as it pertains to a dip, is a vulnerable position that may have previously been overlooked.
Deep Cryogenic Treatment of Plain-Carbon and Low-Alloy Steels
Authors: Sondar Pavankumar R. , Hegde Subray R. 
Published: July 2020

Abstract
To improve the mechanical properties of steels, cryogenic treatment is often carried out as an intermediate step between quenching and tempering. The transformation of retained austenite into martensite is the main objective and principle behind the cryogenic treatment. Generally, high-alloy and high-carbon steels are subjected to cryogenic treatment, as they produce a high fraction of retained austenite during quenching as compared with low- and medium-alloy steels. This work analyses the effect of cryogenic treatment on EN8, a plain-carbon steel, and EN47, a low-alloy steel, through microstructural characterization, hardness measurements, and tensile tests. The work shows that influence of cryogenic treatment carried out after tempering is only marginal, whereas cryogenic treatment carried out before tempering yields much better mechanical properties. Experimental results obtained in this work confirm that EN47 responds slightly better than EN8 suggesting that low-alloying additions influence the cryogenic treatment of steels. This work established that by properly applying cryogenic treatment, the strength and hardness of both EN8 and EN47 steels can be increased by about 50 MPa and 3 HRC, respectively, as compared with conventional hardening and tempering treatment.
Az elhízás jelenlegi és prognosztizált betegségterhe a magyarországi romák körében II.

Absztrakt:
Bevezetés: Az elhízás, valamint az elhízással összefüggő
krónikus, nem fertőző betegségek prevalenciája növekszik a roma populációban. Az
elhízás megelőzését és csökkentését célzó beavatkozások fejlesztésére és
tesztelésére fordított hatalmas erőforrások ellenére kevés információ áll
rendelkezésre az evidencián alapuló intervenciós programok hatékonyságáról.
Célkitűzés: A roma populációban különböző életkori
kategóriákban végrehajtott, eltérő intenzitású intervenciós programok hatásainak
modellezése a beavatkozások végrehajtása után bekövetkezett tápláltsági állapot
változásában. Módszer: A különböző népegészségügyi
beavatkozások hatása a roma lakosság egészségi állapotára a Dynamic Modeling for
Health Impact Assessment szoftverrel került meghatározásra. A szerzők a kutatás
során kétféle modellbeavatkozást hasonlítottak össze: az elhízás prevenciójának
egy tényezőjére, a nagy cukor-, só- és zsírtartalmú élelmiszerek reklámozásának
korlátozására fókuszáló intervenciós programokat és a komplex beavatkozás elvére
épülő, az életmód egészét megváltoztató intervenciós programok tápláltsági
állapotra gyakorolt hatását térképezték fel. Eredmények: A roma
férfiak és nők közel 20%-a szenved elhízásban jelenleg, népegészségügyi
beavatkozás nélkül 2070-re a romák egyharmada lesz túlsúlyos és elhízott. Az
elhízás egy tényezőjére fókuszáló intervenciós programok még akkor sem adnak
érzékelhető eredményt az elhízás társbetegségeinek incidenciáját és
prevalenciáját tekintve, ha a szakirodalomban bemutatott, jelenleg
leghatékonyabb eljárásokat alkalmazzák. Ezen intervenciós programok hatása a
statisztikai kimutathatóságot is alig éri el. A teljes életmódváltást segítő
intervenciós programok elsősorban a közép- és időskorú roma népesség esetén
adhatnak érzékelhető eredményt. Az elhízásban szenvedő középkorú férfiak aránya
0,42%-kal, a nők aránya 0,35%-kal csökken. Következtetés: A
kutatás eredményei arra hívják fel a figyelmet, hogy a roma lakosság körében a
tápláltsági állapot normalizálása és az elhízás kísérő betegségeinek csökkentése
komplex, rasszspecifikus beavatkozást igényel. Orv Hetil. 2020; 161(27):

Bevezetés: A jóindulatú pajzsmirigygöbök gyakori elváltozások,
kezelést azonban ritkán igényelnek. Panaszokat okozó, gyorsan növekvő, túlműködő
göbök kezelésére a rádiófrekvenciás ablatio mint hőablatiós módszer hatékony
alternatív lehetőség, melyet ezen indikációban hazánkban elsőként alkalmaztunk.
Célkitűzés: Ismertetjük a jóindulatú pajzsmirigygöbök
rádiófrekvenciás ablatiós kezelési sajátosságait, fontosságát, és értékeljük
saját klinikai eredményeinket. Módszer: 2016. június és 2019.
szeptember között 140 páciens 186 pajzsmirigygöbét kezeltük a páciensek
kiválasztását követően. A beavatkozások előtt és után meghatároztuk a kezelt
göbök térfogatát, legnagyobb átmérőjét és a térfogatcsökkenést a vizsgált
időszakban. Betegeinket legalább fél évig utánkövettük, az
átlagos követési idő 12,5 ± 5,9 hónap volt. Eredmények: A
kontrollvizsgálatok során kapott eredmények alapján az elváltozások mérete és
erezettsége csökkent. Az átlagos térfogatcsökkenés 44,7 ± 17,6% volt az első
hónap végére és 72,9 ± 17,9% a hatodik hónap után. Összesen 3 minor szövődményt
észleltünk. Következtetés: A rádiófrekvenciás ablatio a
jóindulatú pajzsmirigygöbök kezelésére jól használható, hatékony eljárás, mely
válogatott esetekben a sebészi kezelés értékes alternatívája. Orv Hetil. 2020;

Absztrakt:
Bevezetés: Retrospektív munkánkban az elmúlt 12 év alatti két, 5
éves időszakban vizsgáltuk a tüdőmetastasisok szövettan szerinti megoszlásában
és a metastasectomiák típusában végbement változásokat. Célkitűzés és
módszer: Az első csoportban (2006–2010) 55 beteg volt: férfi 54,5%
(n = 30), nő 45,5% (n = 25), átlagos életkor 57,9 év (24–80); a második
csoportban (2014–2018) 115 beteg volt: férfi 60% (n = 69), nő 40% (n = 46),
átlagos életkor 62,2 év (26–82). Eredmények: Az első időszakban
a rectumban 19,3%-ban (n = 11), a colonban 17,5%-ban (n = 10), a vesében 14%-ban
(n = 8) volt a primer tumor, a második periódusban a colonban 23,1%-ban (n =
31), a rectumban 15,7%-ban (n = 21), a vesében 9%-ban (n = 12). A műtétek
megoszlása: atípusos reszekció: 38,6% (n = 22) és 46,3% (n = 62); lobectomia
31,6% (n = 18) és 26,9% (n = 36); pulmonectomia 10,5% (n = 6) és 1,5% (n = 2);
segmentectomia 7% (n = 4) és 9,7% (n = 13); bilobectomia 1,8% (n = 1) és 0,7% (n
= 1) az első és a második csoportban, egyenként. Az első periódusban végzett
’video-assisted thoracic surgery’ (VATS) műtétek aránya 5,3%-ról (n = 3) a
második periódusban 64,9%-ra (n = 87) növekedett. A primer tumor műtéte és a
tüdőáttét eltávolítása közötti betegségmentes időszak az első csoportban
átlagosan 45,2 hónap (0–144), a másodikban átlagosan 33,8 hónap (0–180) volt. Az
első periódusban észlelt 39 hónapos medián túlélés a második csoportban 59
hónapra emelkedett. Az átlagos 5 éves túlélés mindkét csoportunkban 41% volt.
Következtetés: Az elmúlt 12 év alatt a tüdőáttétek
eltávolításán átesett betegek száma a kétszeresnél is jobban megemelkedett, és
jelentősen nőtt a VATS-metastasectomia aránya (5,3% vs. 64,9%). A primer tumoros
megoszlásban nem találtunk jelentős eltérést. A medián túlélés a második
csoportban némileg jobbnak bizonyult. Orv Hetil. 2020; 161(29): 1215–1220.
