Approximate Fuzzy Inverse Matrix Calculation Method using Scenario-based Inverses and Bisection
Authors: GÜNAY AKDEMİR Hande
Published: January 2023

In this paper, we introduce a numerical method to construct the inverse of a square matrix whose elements are trapezoidal or triangular fuzzy numbers (FNs). A set of fuzzy linear equations is required to be solved in order to determine the fuzzy inverse matrix. The proposed technique first iteratively searches the possible solution intervals and then narrows those too-wide estimated intervals via bisection. Using interval arithmetic in left and right matrix multiplication, we aim to approximate the identity matrix as a result of product operations. The dissimilarity of the endpoints of intervals belonging to multiplication matrices with the identity matrix is considered to be an error function to be minimized. In this way, even if the entries of a matrix are uncertain, the fuzzy inverse matrix containing all inverse matrices can be found quickly with the use of computer technology. The method is explained, and comparisons are drawn with inverse stable examples from the literature.
MULTI-LEVEL STUDENT PEER ASSISTED MENTORING (MSPAM) OF COMPUTER SCIENCE FEMALE STUDENTS AT UNDERGRADUATE
Authors:   University Of Zambia, Musonda Chalwe , M.K Kabemba Monde ,   University Of Zambia
Published: January 2023

- The percentage of female students majoring in computer science is much smaller than that of male students. Computer science has one of the lowest shares of women degree recipients among the broader field of Science and Engineering, with reports of only nineteen percent of the computer science degrees in 2016 been awarded to women at University of Zambia. As such, fewer women than men enter the computing profession, leading to a gender disparity in the computing workforce. A number of factors as suggested as contributing to the current state of poor performance of female in the computing field: women lack confidence; negative stereotype; male orientated culture; lack of appropriate role models in the field, self-efficacy, the curriculum is not tailored to suit their interests and many more, that contribute to this disparity. One way to improve the current state of Female in computer science is to mentor female in the computer science at both undergraduate and in industry. The study used mixed methodology to collect data which are observation, interviews, Literature review, asking questions, gathering information and then presenting the facts. This study proposes Multi-level Student Peer Assisted Mentoring (MSPAM) computer science female at undergraduate, an approach to optimize peer mentoring by organizing mentors into levels.

This paper presents a comparative study using a newly technology called water jets cavitation to fabricate micro feature on 304 stainless steel foils with a thickness of 100 µm and surface enhancement of 8090AlLi alloy sample with a thickness of 4 mm, where angular nozzle and a designed cavitation system were used with an incident pressure of 8-20 MPa. The bulged sample and the effect of incident pressure on the cavitation zone range were investigated. The experimental results indicated that the formed sample bulging depth of the outer ring shock zone and the bulging depth of the jet shock zone were not ideal, while the pits in the cavitation shock zone (that is, pits 2~4 and 10~12) obtained good geometric characteristics. Finally, the consistency of the maximum bulging depth was relatively good. The micro-bulged parts showed that the micro-pits in the cavitation shock zone had a large bulging depth and their uniformity was relatively good, indicating that the circular array feature micro-die has good performance in the cavitation water jet shock micro-bulging process. The effect of incident pressure on the range of cavitation zone, also indicated that the effective area of action of the cavitation water jet showed a ring. That is when the incident pressure was 20 MPa with a target distance of 120 mm, the maximum cavitation shock (bulging) zone showed rings of 3.5 ～21.1 mm with the 304 stainless steel foil and 3.5 mm~21.4 mm also with the 8090Al-Li alloy plate which were approximately same.

Published: January 2023

Flood disaster has become a significant natural concern to so many rural and urban dwellers in different part of the world, with devastating effects that cannot be overemphasized. Previous studies have discussed causative factors and preventive measures of flooding. However, significant underpinning factors such flood incidence, hazard proximity and delineation of flood vulnerable areas which determine flooding severity and wide scale coverage are often obscured. The situation creates a knowledge gap which this study intends to fill by evaluating the causes of flood in Kaduna South Local Government Area and proffer mitigation strategies. The descriptive survey research design was employed in the study and a total 418 structured questionnaire was shared among residents and professionals in the built environment. Data was presented on tables and analyzed using the relative importance index ranking method so as to determine the severity of the factors that causes flooding and the mitigation measures that are appropriate to tackle the problem. The result of the study showed that 34.36% of the residents have experience flood at least 3 times in single rainy season, while 11.04% and 2.76% of the residents have experience flood at least 6 and 9 times respectively in a single season. Hazard proximity reveals 19.94% of residential buildings located are within 0.1-0.5 km and 13.49% are located within 0.5-1.0 km away from the flood source. Consequently, river overflow with a severity index of 0.31 is the highest cause of flooding in the study area, followed by poor drainage systems and heavy rainfall with Severity index of 0.29 and 0.28 respectively. The study also suggested mitigation measures as good drainage network and stop building on flood plains jointly rank first with a significance index of 0.30, building embankments and implement government policies on flood with 0.28 and 0.27 respectively. Therefore, the authority of Kaduna State Urban Planning and Development should ensure widening and desilting of drainages, the demolition of illegal structures built across the drainage channels and the implementation of government policies on flood.
STUDY OF SHRINKAGE OF CONCRETE USING NORMAL WEIGHT AND LIGHTWEIGHT AGGREGATE
Authors: Rahaman Taufiqur , Islam Dr. Md. Shafiqul ,   Rajshahi University of Engineering & Technology
Published: January 2023

Drying shrinkage can be a major cause of deterioration of concrete structures. Aggregate sizes, curing period and water-cement ratio imparts a great impact on shrinkage of concrete. This paper represents the observed effects of water-cement ratio, curing period and aggregate sizes on shrinkage of concrete using normal weight and lightweight aggregate. Structural lightweight aggregate concrete offers several benefits as compared to the normal weight concrete. This paper checks the suitability of using lightweight concrete instead of normal concrete in case of susceptibility to shrinkage. Though the cost of the production of the lightweight aggregate is high due to energy and raw material consumption, economy can be achieved by using locally available waste materials to produce lightweight aggregates. The experiments were carried out according to ASTM C157 and ASTM C490. The variations of aggregate sizes, curing period and the water-cement ratio were applied and their effects were observed on shrinkage of concrete. This paper also recommends the proper type of concrete owing to minimal shrinkage.
Performance Risks During Surface Extravehicular Activity and Potential Mitigation Using Multimodal Displays
Authors: Zhang Johnny Y. , Anderson Allison P.
Published: January 2023

BACKGROUND: Surface extravehicular activity (sEVA) will be a critical component of future human missions to the Moon. sEVA presents novel risks to astronaut crews not associated with microgravity operations due to fundamental differences in task demands, physiology, environment,
and operations of working on the lunar surface. Multimodal spacesuit informatics displays have been proposed as a method of mitigating sEVA risk by increasing operator autonomy.METHODS: A formalized literature review was conducted. In total, 95 journal articles, conference papers,
and technical reports were included. Characteristics of U.S. spacesuits were reviewed, ranging from the Apollo A7L to the xEMU Z-2.5. Multimodal display applications were then reviewed and assessed for their potential in aiding sEVA operations.RESULTS: Through literature review
25 performance impairments were identified. Performance impairments caused by the spacesuit represented the greatest number of sEVA challenges. Multimodal displays were mapped to impairments and approximately 36% of performance impairments could be aided by using display interfaces.DISCUSSION:
Multimodal displays may provide additional benefits for alleviating performance impairments during sEVA. Utility of multimodal displays may be greater in certain performance impairment domains, such as spacesuit-related impairments.Zhang JY, Anderson AP. Performance risks during
surface extravehicular activity and potential mitigation using multimodal displays. Aerosp Med Hum Perform. 2023; 94(1):34–41.
Aviation Decompression Sickness in Aerospace and Hyperbaric Medicine
Authors: Kutz Craig J. , Kirby Ian J. , Grover Ian R. , Tanaka Hideaki L.
Published: January 2023

INTRODUCTION: The U.S. Navy experienced a series of physiological events in aircrew involving primarily the F/A-18 airframe related to rapid decompression of cabin pressures, of which aviation decompression sickness (DCS) was felt to contribute. The underlying pathophysiology
of aviation DCS is the same as that of diving-related. However, based on the innate multifactorial circumstances surrounding hypobaric DCS, in clinical practice it continues to be unpredictable and less familiar as it falls at the intersect of aerospace and hyperbaric medicine. This retrospective
study aimed to review the case series diagnosed as aviation DCS in a collaborative effort between aerospace specialists and hyperbaricists to increase appropriate identification and treatment of hypobaric DCS.METHODS: We identified 18 cases involving high-performance aircraft emergently
treated as aviation DCS at a civilian hyperbaric chamber. Four reviewers with dual training in aviation and hyperbaric medicine retrospectively reviewed cases and categorized presentations as “DCS” or “Alternative Diagnosis”.RESULTS: Reviewers identified
over half of presenting cases could be attributed to an alternative diagnosis. In events that occurred at flight altitudes below 17,000 ft (5182 m) or with rapid decompression pressure changes under 0.3 atm, DCS was less likely to be the etiology of the presenting symptoms.CONCLUSIONS:
Aviation physiological events continue to be difficult to diagnose. This study aimed to better understand this phenomenon and provide additional insight and key characteristics for both flight physicians and hyperbaric physicians. As human exploration continues to challenge the limits of sustainable
physiology, the incidence of aerospace DCS may increase and underscores our need to recognize and appropriately treat it.Kutz CJ, Kirby IJ, Grover IR, Tanaka HL. Aviation decompression sickness in aerospace and hyperbaric medicine. Aerosp Med Hum Perform. 2023; 94(1):11–17.
Cabin Pressure Altitude Effect on Acceleration Atelectasis After Agile Flight Breathing 60% Oxygen
Authors: Tank Henry , Kennedy Gareth , Pollock Ross , Hodkinson Peter , Sheppard-Hickey Rebecca-Anne , Woolford Jeffrey , Green Nicholas D. C. , Stevenson Alec
Published: January 2023

INTRODUCTION: A flight trial was conducted to determine whether breathing 60% oxygen during high performance flight maneuvers using contemporary pilot flight equipment induces atelectasis and to explore whether cabin altitude had any influence on the extent of atelectasis identified.METHODS:
On 2 separate days, 14 male aircrew flew as passengers at High [14,500–18,000 ft (4420–5486 m)] and Low [4000–6000 ft (1219–1829 m)] cabin pressure altitude in a Hawk T Mk1 aircraft breathing 60% oxygen. Sorties comprised 16 maneuvers at +5 Gz, each sustained
for 30 s. Lung volumes (spirometry), basal lung volume (electrical impedance tomography, EIT), and peripheral oxygen saturation during transition from hyperoxia to hypoxia (pulmonary shunt fraction) were measured in the cockpit immediately before (Pre) and after (Post) flight.RESULTS:
Forced inspiratory vital capacity (FIVC) was significantly lower Postflight after High (−0.24 L) and Low (−0.38 L) sorties, but recovered to Preflight values by the fourth repeat (FIVC4). EIT-derived measures of FIVC decreased after High (−3.3%) and Low (−4.4%) sorties
but did not recover to baseline by FIVC4. FIVC reductions were attributable to decreased inspiratory capacity. Spo2 was lower Postflight than Preflight in High and Low sorties.DISCUSSION: Breathing 60% oxygen during flight results in a 3.8–4.9% reduction
in lung volume associated with a small decrease in blood oxygenation and an estimated pulmonary shunt of up to 5.7%. EIT measures suggest persisting airway closure despite repeated FIVC maneuvers. There was no meaningful influence of cabin pressure altitude. The operational consequence of
the observed changes is likely to be small.Tank H, Kennedy G, Pollock R, Hodkinson P, Sheppard-Hickey R-A, Woolford J, Green NDC, Stevenson A. Cabin pressure altitude effect on acceleration atelectasis after agile flight breathing 60% oxygen. Aerosp Med Hum Perform. 2023; 94(1):3–10.

BACKGROUND: The purpose of this report is to document the first use of a single piece, posterior chamber phakic implantable collamer lens (ICL) with a central port in the right eye (OD) of a spaceflight participant (SFP) during a 12-d Soyuz mission to the International Space
Station (ISS). We also briefly document the stability of a pre-existing pachychoroid pigment epitheliopathy (PPE) in the macula of his left eye (OS) during this mission.CASE REPORT: Ocular examination, including refraction, slit lamp examination, macular examination by optical coherence
tomography (OCT), and tonometry were performed before and after his mission and he was questioned regarding visual changes during each portion of his flight.DISCUSSION: We documented no change in ICL position during his spaceflight. He reported stable vision during liftoff, entry
into microgravity, 12 d on the ISS, descent, and landing. Our results suggest that the modern ICL with a central port is stable, effective, and well tolerated during short duration spaceflight. His PPE also remained stable during this mission as documented by OCT.Gibson CR, Mader TH,

This study was carried out to investigate the effect of gender and living place on the number of falls, the risk of falling, the fear of falling, and balance of older people. A total of 148 volunter elderly individuals (59 women and 89 men living in a nursing home and home) participated in this study. According to the 2X2 ANOVA analysis results; gender showed a statistically significant effect on the number of falls (df = (1, 140), F = 5,777, p= .018), fear of falling (df= (1, 140), F=4,609, p=.034), risk of falling (df= (1, 140), F=5,999, p=.016), functional reach test scores (df= (1, 140), F=10,866, p=.001). Older women were more likely to fall than older men, had a higher risk of falling, fear of falling, and a poorer balance. Living place was showed statistically significant effect on fear of falling (df= (1, 140), F=36,854, p=.000), risk of falling (1, 140), F=5,750, p=.018). While elderly people living in the house had more fear of falling than the elderly living in the nursing home, the older people living in the nursing home had a higher risk of falling than those living at home. Gender*living place interaction had a significant effect on fear of falling (df= (1,140), F=12,056, p=.001). It was observed that both older men and women living at home had more fear of falling than older men and women living at nursing homes. According to Independent Sample t test; Functional reach test scores (balance skills) were found to be higher in the elderly who had a low fall risk. In conlusion; to prevent falls and to take precautions, the risk of falls, fear of falling and balance skills of the elderly should be monitored on a regular basis.

Ortaöğretim
öğrencilerinin beden eğitimi ve spor (BES) dersine ilişkin tutumlarını
inceleyen çalışmaların sonuçları değişkendir; araştırmalar sıklıkla belirli
değişkenlere ilişkin benzer biçimde anlamlı fark bulurken farklı sonuçlar veren
araştırmalar da bulunmaktadır. Bu
araştırmanın amacı, lise öğrencilerinin BES dersine yönelik tutumlarının
düzeylerini ve bazı değişkenler açısından bu düzeylerde anlamlı fark (α=0.05) olup
olmadığını incelemektir. Tarama modeliyle gerçekleştirilen araştırmaya Balâ ilçe merkezindeki liselerde öğrenim
gören toplam 466 (188 kız, 278 erkek) öğrenci katılmıştır. Bilgi formu ve “Ortaöğretim
Öğrencilerinin Beden Eğitimi Dersine İlişkin Tutum Ölçeği” kullanılarak
toplanan verilerin analizleri SPSS-21 ve LISREL-8.8 programlarında gerçekleştirilmiştir.
Öğrencilerin BES dersine ilişkin tutumları “kararsıza yakın” bulunmuştur. Katılımcılardan
(a) erkek öğrencilerin puanları kız öğrencilere göre, (b) Sağlık Meslek Lisesi
öğrencilerinin puanları ise diğer bazı liselere göre anlamlı düzeyde daha
yüksek bulunmuştur. Ayrıca, (c) okullarındaki spor alanlarını yeterince
kullanabildiğini ifade eden öğrencilerin puanları kısmen kullanabildiğini ve
kullanamadığını ifade edenlere göre, (d) her zaman spor yaptığını ve fiziksel
aktiviteye katıldığını belirtenlerin puanı “ara sıra”, “nadiren” ve “hiçbir
zaman” cevabını verenlere göre ve (e) bir kulüpte bazen spor yapanların
puanları hiç yapmadığını belirtenlere göre anlamlı düzeyde daha yüksek
bulunmuştur. İlçede BES dersine ilişkin kararsıza yakın tutum düzeyleri ile bu
düzeylerde daha da olumsuz puanlara sahip olan gruplar göz önünde
bulundurularak uygun araştırma, uygulama ve politikaların geliştirilmesine
ihtiyaç vardır.

Egzersizin
insan sağlığına çok yönlü faydaları konusunda günümüzde en dikkat çeken
konulardan birisi bilişsel sağlığa olan yararlarıdır. Yönetici
işlevler, bir amaca ulaşmak için planlama, bilgiyi kullanma, soyut düşünme ve
çıkarımlar yapma gibi birçok özelliği içine alan bir kavram olmakla birlikte
aerobik egzersiz ile ilişkisi sık sık çalışılmaktadır.  Bu çalışmanın amacı sporcu popülasyonunda,
orta ve yüksek şiddetli aerobik egzersizin yönetici işlevlerin ana
fonksiyonlarından biri olan bozucu etkiye direnç üzerindeki etkisini incelemektir.
Bu çalışmaya herhangi bir kronik hastalığı
bulunmayan ve en az 3 yıldır aktif olarak spor yapan 16 sağlıklı erkek
katılımcı (=21.31±1.4
yıl) dahil edilmiştir. Araştırma deseni olarak randomize karşılıklı dengeli
çalışma dizaynı uygulanmıştır. Katılımcılar test süresince toplamda 4 ayrı gün
laboratuvara gelmişler ve deneysel koşullar (orta ve yüksek şiddetli aerobik
egzersiz ve dinlenme) için laboratuvara geliş sıraları karşıt dengelenmiştir.
Katılımcılar orta şiddetli aerobik egzersiz için %60, yüksek şiddetli aerobik
egzersiz için %80 kalp atım rezervinde 30 dakikalık egzersiz yapmışlardır.
Dinlenme koşulunda ise egzersiz koşullarında geçen süre kadar dergi ve
kitapların olduğu sessiz bir odada oturmaları sağlanmıştır.  Test koşullarının öncesinde ve 15 dakika
sonrasında bozucu etkiye direnç ölçümleri için Stroop testine alınmışlardır.
Verilerin değerlendirilmesinde SPSS 22.0 paket programı kullanılmıştır.
Katılımcıların farklı koşullardaki Stroop testi performansları arasındaki
farkın belirlenmesi Two-Way Anova analizi ile gerçekleştirilmiştir.
İstatistiksel analiz sonuçlarına göre; Stroop testi doğru sayılarına ilişkin
koşullar arası anlamlı bir farklılığa rastlanmamıştır (p>0,05).
Katılımcıların Stroop testi reaksiyon zamanları orta ve yüksek şiddetli aerobik
egzersiz koşullarında, dinlenme koşuluna göre anlamlı düzeyde azalmıştır
(p<0,05). Sonuç olarak bu çalışmada orta ve yüksek şiddetli aerobik
egzersizin bozucu etkiye direnç üzerinde olumlu bir etkisinin olduğu ortaya
konmuştur.

Published: January 2023

Bu araştırmanın amacı, serbest zaman etkinliklerine
katılan bireylerin katıldıkları etkinliklere ilişkin ilgilenim düzeylerini
ölçmek amacıyla Kyle, Absher, Norman, Hammitt ve Jodice (2007) geliştirilmiş
olan ‘Serbest Zaman İlgilenim Ölçeği’nin (SZİÖ) Türkçe’ye adaptasyon
çalışmasını yapmaktır. Araştırmanın örneklem grubunu, Ankara’nın farklı
ilçelerinde hizmet veren 5 farklı fitness merkezinin üyesi 85’i kadın ve 224’ü
erkek toplam 309 kişi oluşturmuştur. 
Katılımcıların yaş ortalamaları 25.78 ± 7.041’dir. SZİÖ’nin orijinal formu toplam beş alt
boyut ve 15 beş maddeden oluşmaktadır. Elde edilen verilerin analizinde,
tanımlayıcı istatistiklere ek olarak Doğrulayıcı Faktör Analizi (DFA), basit
korelasyon ve iç tutarlık katsayıları hesaplanmıştır. Ölçeğin yapı
geçerliği için uygulanan Doğrulayıcı Faktör Analizi’nde (DFA) orijinal formla
tutarlı olarak ölçek Türkçe versiyonunun da 5 alt boyut ve toplam 15 maddeden
oluştuğu belirlenmiştir. Ölçeğin faktör yüklerinin 0.41-0.81 arasında değiştiği
tespit edilmiştir. Ölçeğin Cronbach Alfa iç turarlık katsayılarının 0.58
(özdeşleşme) ile 0.80 (çekicilik) arasında değiştiği bulunmuştur. Elde edilen
sonuçlara göre, Türk kültürüne uyarlanan T-SZİÖ’nin bireylerin serbest zaman
ilgilenim düzeylerinin belirlenmesi için geçerli ve güvenilir bir ölçme aracı olduğu
ifade edilebilir.
