The Flowering Mantis
Authors: Ingalhalikar Shrikant
Published: July 2023

The article describes various instances of animals using camouflage and mimicry in nature. It mentions animals like the fox, donkey, and jackal attempting to disguise themselves with different hides, but not succeeding. It also highlights how some animals successfully use mimicry for protection or attack. The author shares their experience of observing a praying mantis, specifically the Gongylus gongylodes species, which disguises itself as a flower to attract and capture prey, such as butterflies. The author is fascinated by this encounter and captures their observations through photography, despite missing the moment of the mantis's successful hunt.
The Herbal Hunters
Authors: Ingalhalikar Shrikant
Published: July 2023

The article describes the behaviour of two types of carnivorous plants, Droseras and Utricularias, found in the Sahyadri region. The Droseras, also known as Sundew Plants, have sticky dewdrops on their leaves that trap and digest insects. They exhibit intelligent responses to stimuli and have tentacles that grip the insects like a palm. On the other hand, Utricularias, also known as Bladderworts, have bladders with digestive juices that trap insects. Both plants are considered carnivorous and are referred to as herbal hunters for their insect-catching abilities.
Pole and Wire Associated Birds Of Deccan Area
Authors: Nalavade Sanjeev B.
Published: July 2023

The article explores the association between birds and the man-managed element of poles and wires in the Deccan region. The study identifies various reasons why birds have adopted poles and wires, such as foraging, prey capture, courtship, nesting, and migration. The research findings reveal that out of 105 bird species, 20 mainly use poles, 35 mainly use wires, and 51 use both elements. The level of association varies among species, with casual use being the most common. The study emphasizes that the linkage between birds and poles and wires is relatively weak and dependent on the surrounding habitat. The article provides a list of bird species associated with poles and wires in the Deccan region.

A obesidade, principalmente a mórbida – IMC maior ou igual a 40 kg/m 2 - tem sido apontada como um dos principais fatores de risco para o desenvolvimento de Diabetes Mellitus tipo 2 (DM2). Uma das opções de tratamento da obesidade e para DM2 é a cirurgia bariátrica. Este é um estudo transversal, analítico e retrospectivo com base em prontuários de pacientes submetidos à cirurgia bariátrica em um hospital secundário de Fortaleza, Ceará, no período de novembro de 2018 a fevereiro de 2021, avaliando o perfil glicêmico pré e pós-operatório. Em nosso estudo, após os critérios de inclusão e exclusão foram selecionados 18 pacientes. Todos os pacientes apresentaram perda de peso significativa no pós-operatório no período de avaliação, com melhora do IMC, geralmente, tendo mudança da classificação. Apenas um paciente não alterou classificação IMC, mantendo-se ainda obeso mórbido e com perda de peso sutil. De modo geral, no momento anterior à terapia cirúrgica, quinze indivíduos faziam uso de alguma terapia hipoglicemiante, desses, dois usavam insulina e hipoglicemiantes orais. No seguimento, dezesseis pacientes não faziam uso de nenhuma medicação para controle glicêmico e 02 mantiveram uso de hipoglicemiantes orais, desses, um paciente era insulinodependentes. Foi observado diferença significativa entre o uso de medicações pré e pós-operatória, com p < 0,001.
Factors Affecting Iraqi Academic Leaders' Communicative Competence in English: A Sequential Mixed Methods Study
Authors: Saeed Halah Kamal , Razak Norizan Abdul , Aladdin Ashinida Binti
Published: July 2023

English language communicative competence represents an academic leader's ability to use language effectively. However, to date, Iraqi academic leaders’ communicative competence has not been as effective as predictable and leads to lower intake of international students in Iraqi universities. This paper presents the findings of a study which explored the factors affecting Iraqi academic leaders’ communicative competence in English. The study adopted an exploratory sequential design, where nine semi-structured interviews were conducted online with academic leaders, followed by  questionnaire distribution to 108 additional academic leaders. The participants for both parts of the study were from various universities in Iraq. The data collection and data analysis for the research were guided by four theories, namely the communicative competence theory, communication theory, theory of planned behaviour and leadership competence model. Data collected from the interviews were transcribed and analysed thematically. Data from the questionnaires were analysed descriptively and inferentially using SPSS (v.20). The most significant findings were that cultural factors, a positive attitude towards communicative ability, efficiency in communication, collaboration, problem-solving, and critical skills were the factors that affected the Iraqi leaders’ communicative competence. Finally, a model for developing communicative competence among Iraqi academic leaders was formulated based on the findings. The model consists of training programmes for communicative competence development using digital tools for language use, an electronic examination process with efficient monitoring, and language initiatives for enhancing Iraqi academic leaders' communication competence.
Monitoreo de covid-19 en un municipio de la triple frontera – Brasil, Paraguay y Argentina: un análisis cuantitativo y actual de casos confirmados, hospitalizaciones y muertes
Authors: Ramos da Silva David , Guerra López Seidel
Published: July 2023

El objetivo de este trabajo es analizar el número de casos confirmados, número y tasa de ingresos hospitalarios y muertes por COVID-19 en Foz do Iguaçu/Paraná. En este municipio inicialmente las notificaciones e investigaciones de los casos de COVID-19 estaban centralizadas en la Vigilancia Epidemiológica Municipal y cuando se identificó la transmisión comunitaria, las unidades de Atención Primaria de Salud pasaran a la atención y manejo de los casos sospechosos de la enfermedad, confiriéndole mucha relevancia a la búsqueda activa de pacientes sintomáticos. Tratase de un estudio observacional descriptivo con enfoque cuantitativo sobre la población enfocada. Se incluyeron en la muestra todos los casos confirmados, hospitalizados y óbitos presentados en el Boletín Epidemiológico diario emitido por la Secretaría Municipal de Salud de Foz do Iguaçu/PR, desde el 19 de julio del año 2019 hasta el 14 de enero del aaño 2022. Al analizar los resultados se constató un aumento exponencial en el número de casos confirmados, pero en relación al mismo período del año anterior hubo una reducción significativa en el número de muertes por COVID-19. Varios reportes plantean que la reducción de las muertes, así como la disminución de la presentación de formas graves de COVID-19, se debe a la vacunación masiva y a las campañas de educación y orientación sobre las formas de contagio por SARS COV 2.

Published: July 2023

Background:
Echinococcosis is a parasitic and zoonotic disease, usually caused by Echinococcus granulosus or Echinococcus multilocularis, and threatens the health and development of human societies. Worldwide, 3.6 million disability adjusted life years (DALYs) may be lost due to echinococcosis.
Case Description:
In this report, a 44-year-old man was presented, whose first symptoms were psychological and behavioral changes and headache. After investigations, it was found that he had a mass in the frontal part of the brain, in the heart, and left kidney and spleen without any symptoms and involvement in the liver. After surgery to remove a mass in the brain, a pathologic study confirmed that the patient had echinococcosis. After necessary radiological imaging, the patient underwent surgery to remove cysts. The cyst was successfully removed and the patient was started on albendazole. The patient was discharged in good general condition and followed up for 6 months, during which time their general condition remained very good.
Conclusion:
To properly diagnose hydatid cyst disease, a thorough examination of all possible sites of involvement is necessary, even if the patient has no symptoms.

An account of areca nut uses and oral health damages from an Indian perspective
Authors:   Department of Physiology, Surendranath College, University of Calcutta, Kolkata, India, Banerjee Subhrajit
Published: July 2023

There is a perception in India that packaged paan masala and betel quid (BQ) with areca nut loosely called paan supari both being devoid of tobacco are not carcinogenic. This article intends to be an awareness initiative against this notion. It focuses on the use of areca nuts in various forms. An understanding is necessary for the identification of components of gutka, various forms of BQ, and paan masala wherein areca nut is used. Areca nut consumption damages oral health and leads to the development of oral submucous fibrosis (OSF). OSF is used as an umbrella term for depicting all potentially malignant lesions. Gutka is a product popular in India that uses areca nuts and a form of flavored tobacco (zarda) as the main component. Although oral tobacco is implicated as a grade I carcinogen, areca nuts and BQ-containing areca nuts belong to the same grade. Areca nuts are the fourth largest addictive substance in the world. Deleterious effects of areca nuts in various forms are a grossly underreported area of research. Initiatives against areca nut uses are required.

Background:This study aimed to investigate the effects of brimonidine on microglia cell morphology by creatinga transient retinal ischemia model in rats. Methods:In the right eyes of male Wistar rats (n= 12), a transient retinal ischemia model was created. The ratswere divided into three groups: (1) eyes treated with topical brimonidine in the transient retinal ischemia model,(2) sham-treated eyes, and (3) control eyes. Four main phenotypes (ramified, primed, reactive, and amoeboid-phagocytic) of Iba-1 positive microglia cells were examined in the retinal layers. Results:In the transient retinal ischemia model, the number of Iba-1 positive microglia cells was 100.67±7.50 cellsin the sham group and 57.67±14.64 cells in the topical brimonidine group. The decrease in the total number of Iba-1 positive microglial cells was statistically significant (p<0.05). When we compared ramified and primed microgliacells, there was no statistically significant difference between the groups. The number of amoeboid-phagocyticmicroglial cells was 9.5±1.29 cells in the sham treatment group and 2.25±0.50 cells in the topical brimonidinegroup (p<0.05). There was a statistically significant decrease in the number of reactive and amoeboid cells. Conclusion:Studies in the central nervous system in rats demonstrated that cell metabolism and functions werechanged after acute injury and that microglia transformed from a ramified form to an amoeboid-phagocytic form.In this study, the decrease in the transition of cells from ramified to reactive and amoeboid forms showed us thattopical brimonidine treatment could have neuroinflammation suppressor features.

Neka zapažanja u vezi sa visinama stabala
Authors: Panić Đorđe
Published: July 2023

Razvoj stabala u visinu je, sa svima svojim zakonitostima, interesantan već kao takav. Medjutim, kvantitativne i kvalitativne karakteristike visina stabala imaju svog praktičnog značaja u šumarstvu, naročito u uredjenju šuma, u prvom redu kod stabala kao sastavnog dela sastojine. Pored opštih zapažanja, ova studija je orijentisana na posebna zapažanja u čistim bukovim šumama Srbije. Ove se šume, u sadašnjoj fazi razvoja, ističu svojim tzv. prelaznim sastojinskim oblicima, tj. ispoljavaju nedostatak tipičnih sastojinskih oblika i pored "prebirnog" načina gazdovanja, koji je ovde primenjivan.

Proizvodni ciklus u iskorišćavanju šuma, pod kojim podrazumijevamo proces roda koji počinje s prvom operacijom (priprema radnog mjesta, obaran je stabla), a završava s posljednjom operacijom (uskladišteniem drvnih sortimenata na stovarištu ili njihovom isporukom kupcu), predstavlja jedinstven proces na istom predmetu rada.Vrijeme proizvodnog ciklusa se sastoji od:

- vremena neposrednog procesa proizvodnje tokom kojega se obavljaju tehnološke operacije (obaranje stabla, izrada sortimenata i drugo);

- vremena prekida u procesu proizvodnje (prekidi izmedju operacija, nedostatak goriva, energije i dr.).

Organizaciono-tehničke mjere moraju biti usmjerene na bolje korišćenje vremena neposrednog procesa proizvodnje, odnosno na smanjivanje dužine trajanja vremena prekida u procesu proizvodnje. Na efikasnost korišćenja raspoloživog vremena utiču brojni faktori, različiti po vrsti, intenzitetu i pravcu djelovanja. Svakako, medju njima naročito se ističu:

- organizacija angažovane sile živog rada,

- stepen tehničke opremljenosti rada,

- uslovi rada u šumi.

U svojoj metodološkoj studiji "NAČELA RASPODJELE U ŠUMARSTVU" (Zagreb, 1971.), prikazali smo odnosnu problematiku. Pri tome smo odvojeno prikazali kako bi trebalo postupati po pojedinoj finansijskoj posljedici pojedinog uzroka koji je karaktera objektivnog, subjektivnog ili mješovitog, s obzirom na utjecaj od strane radnog kolektiva radne jedinice. Pored toga, obuhvatili smo odnosnu problematiku djelatnosti šumskoga gospodarenja (proizvodnje drva na panju i iskorišćavanja šuma), dakle, odnosa na relaciji šumarija-šumsko privredno područje (šumsko gospodarstvo), a zatim odnosa drugih djelatnosti (pomoćne, sporedne i nešumarske), dakle, drugih organizacionih jedinica i šumskog gospodarstva (kao cjeline). Napokon smo obuhvatili niz detalja koji se odnose na tu problematiku. Sve to traži znatno predznanje iz ekonomike šumskoga gospodarenja pa i Političke ekonomije, a pri provedbi i znatan stupanj savršenosti poslovanja osobito računovodstvene službe (knjigovodstva).
Sukcesija, koneksija i interakcija mikroorganizama prouzrokovača truleži bukovog oborenog drveta
Authors: Lazarev Vladimir
Published: July 2023

U ovom radu dat je prilog poznavanju sukcesije, koneksije i interakcije mikroorganizama prouzrokovača truleži bukovog oborenog drveta. Bukovo drvo, kao povoljan hranjivi supstrat, služi mnogim mikroorganizmima kao izvor ishrane, a samim tim utiče na njihov vegetativni i generativni, razvoj. Organizmi koji sukcesivno naseljavaju bukovo drvo nalaze se u stalnoj kompeticiji za prostor i hranu.

Iz tog razloga veoma je važan pristup razjašnjenju pojave sukcesije s gledišta ekologije i fiziologije. Prema tom pristupu, mikroorganizmi moraju biti posmatrani kao individue, ali i kao dijelovi ekosistema. Do sukcesije mikroorganizama dolazi postepeno i ona je najtješnje povezana sa interakcijama koje se dešavaju izmedju njih. Dakle, primami organizam koji je u stanju da naseli svježe posječeno bukovo drvo postepeno mijenja supstrat, a kao posljedica odredjene promjene supstrata dolazi do napada raznih drugih sekundarnih i tercijarnih organizama. Ovo "nizanje" mikroorganizama traje sve do potpune dekompozicije supstrata.

Dio nedostatka drveta za kemijsku preradu trebalo je riješiti uzgojem vrsta šumskog drveća brzoga rasta. Uzgajanjem euroameričkih topola, koje su kod nas i u svijetu pokazale velike potencijalne mogućnosti, djelomično namirile bi se potrebe u drvetu za celulozu.

Prije petnaestak godina započelo se kod nas u širim razmjerima sa suvremenim načinom uzgajanja euroameričkih topola (izbor klonova, tehnološki proces proizvodnje sadnog materijala, primjena obrade tla, gnojidba i dr.). Već tada smo se udružili u istraživačke radove zahvaljujući uskoj suradnji sa šumarskom operativom, koja je velikim dijelom i financirala te radove.

Prezentirajući ovo saopćenje, želimo informirati o nekim rezultatima istraživanja ekoloških činilaca, o načinu uzgoja i o uspijevanju euroameričkih topola u regijama koje su bile predestinirane za uzgoj vrsta listača brzoga rasta.

U izlaganju želim upozoriti na vlastiti put uzgoja i gospodarenja šumom u našoj sredini. Ovo upozorenje se temelji na konkretno izloženim motivima i prikazanim metodama u vremenu i prostoru. Uzimam u obzir specifične prirodne uslove naše sredine, kao i našu društvenu sredinu. Izloženo treba shvatiti kao razmišljanje do kojeg se dolazi putujući kroz naše šume i prateći uzgoj šuma u novijem vremenskom periodu. Kada posmatram taj razvitak, nehotimice se sjetim poznate priče o tome kako je neki čovjek noću izgubio u nekom gradu novčanik u neosvjetljenoj ulici i tražio izgubljeno u osvjetljenoj ulici. Kada su ga pitali da li je, zaista, izgubio novčanik na tom mjestu odgovorio je: ne, izgubio sam ga u drugoj ulici, ali tamo nema svjetla.

Prilog proučavanju obnove i njege u sastojinama crnog i bijelog bora

Published: July 2023

Na osnovu Inventure šuma na velikim površinama, koja je u SR BiH provedena u periodu 1964-1968. godine, šume bijelog i crnog bora zauzimaju površinu od 86.003 ha, od koje otpada na društvene šume 81.994 ha i na gradjanske šume 4.009 ha. U odnosu na visoke šume u društvenoj svojini, udio bijelog i crnog bora nije velik i iznosi svega oko 8% od površine visokih šuma (Matić i dr.,1971). Areali ove dvije vrste drveća nisu kompaktni, jer su ove šume zauzele specifična staništa unutar zajednica klimaregionalnog karaktera na krečnjačko-dolomitnim planinama Dinari da i na peri dotitsko-serpentinskom području Bosne (Stefanovi ć i dr., 1975). Ove šume su većinom reliktnog karaktera i potiču iz post- glacijalnog perioda, kada su zauzimale znatno veće površine i kompaktnije areale. Na sužavanju areala imali su svoj uticaj čovjek i listopadna vegetacija, koja je zbog jače konkurentne sposobnosti potisnula borove na ekstremnija staništa (Stefanović i dr., 1975),

S obzirom na vrijednost drveta, borovi su se koristili na uobičajeni način korištenja u BiH - pojedinačno korišćenje stabala, koje je poznato pod imenom "stablimični prebor", iako sa prebornim gospodarenjem nema ničeg zajedničkog, osim što se stabla koriste pojedinačno (Alikalfić, 1971).

S obzirom na značaj ovih šuma i na težnju da se površine pod bijelim i crnim borom prošire i izvan prirodnog areala, a u želji da se sa ovim vrstama drveća gospodari na način koji bi najbolje odgovarao njihovim bioekološkim karakteristikama, te na njihov ekonomski značaj u šumarstvu Bosne i Hercegovine, kao i cjelokupne privrede, na nekoliko najtipičnijih primjera trebalo bi proučiti sastojine crnog bora, i na osnovu konstatiranog stanja odgovoriti na slijedeća pitanja:

1.Kakav treba da je glavni cilj proizvodnje u šumama crnog bora?

2.Na kojim staništima bi trebalo i dalje zadržati crni bor?

3.Koji načini gospodarenja odgovaraju najbolje crnom boru?

4.Koje vrste zahvata treba poduzimati u toku produkcionog perioda kako bi se ostvario postavljeni cilj?

Radni i ekonomski efekti u iskorišćavanju šuma zavise od čitavog niza faktora. Važniji od njih koji direktno utiču na radne i ekonomske efekte rada dijele se, u odnosu na svoje specifičnosti,u dvije osnovne grupe: grupu prirodnih faktora i grupu planskih faktora. U grupu prirodnih faktora spadaju faktori terena, faktori stabla i sastoji ne te vremenski faktori. Osnovne karakteristike ovih faktora su njihova izražena varijabilnost i nemogućnost njihovog oblikovanja u smislu stvaranja povoljnijih uslova rada i postizanja boljih radnih i ekonomskih efekata u vrijeme iskorišćavanja šuma. U vrijeme realizacije iskorišćavanja šuma ovi se faktori moraju akceptirati onakvi kako su dati u konkretnoj situaciji. Za razliku od njih grupa planskih faktora obuhvata komponente tehnologije rada (tehnološki proces rada, sredstva za rad, organizacija i tehnika rada) koje se planiraju i optimiraju u zavisnosti od konstelacije i interakcijskog djelovanja prirodnih faktora u datoj situaciji. Ova uslovljenost tehnologije rada veoma promjenljivim prirodnim faktorima, s jedne, i mogućnost šireg izbora tehnoloških rješenja, naročito u pogledu primjene različitih mehanizovanih sredstava za rad i organizacionih formi rada, s druge strane, stavlja šumarskog stručnjaka pred stalno otvoren problem - koja tehnologija rada u datoj situaciji predstavlja optimalno riješenje. Za rješavanje ovog problema osnovna pretpostavka je poznavanje efekata primjene različitih tehnologija rada u zavisnosti od datih prirodnih faktora - uslova rada. Do ovakvih saznanja se dolazi isključivo naučnoistraživačkim eksperimentalnim radom na terenu.
Intervention of Cotton Picker in Drudgery Reduction of Farm Women
Authors: Lakshmi Velivelli Vijaya
Published: July 2023

Cotton is one of the hugely grown commercial crops in India, mainly in the states of Punjab, Haryana, Rajasthan, Gujarat, Maharashtra and Madhya Pradesh, Telangana, Andhra Pradesh, Karnataka and Tamil Nadu. Provisional data from the Meeting of the COCPC (2021), says that India stands first in the world in acreage with 120.69 Lakh Hectares area under cotton cultivation i.e., around 36% of world area of 333 Lakh Hectares. India is in the top position in the world with an estimated production of 362.18 lakh bales during the cotton season 2021-22 i.e., 23 per cent of the world’s cotton production of 1555 lakh bales. Telangana, the study area produced the highest cotton in South India region i.e., 66.45 lakh cotton bales in 2021-22 season, 14.63 per cent higher than the previous season. This shows the immense potential of the cotton production both in terms of employment and economy. ILO (2019) highlighted that cotton farming is one of the most challenging and labour - intensive activities. Lakhs of migrant and bonded labourers, even children and adolescents are being involved, sometimes as unpaid and invisible labour. Women are majorly involved in cotton picking, which is one of the labour - intensive activity in cotton farming. Despite these problems, mechanization is still lagging in cotton picking activity, which causes lot of drudgery and musculo-skeletal issues among them. This can in turn influence the work efficiency of the labour. Though there are cotton picking machines available in the market, farmers and farm labourers do not purchase and use them as they are unaffordable in price; unaware of the machinery and not sure of its efficiency. With these insights, the current study made an attempt to analyse the drudgery reduction among farm women by using a mechanized cotton picker. The study was conducted on ten farm women involved in cotton picking at Lillipur village of Maheswaram mandal, Telangana. Results showed that most of the sample were having a work experience between 6 - 9 years, worked for 4 - 8 hours per day in the picking season. The perceived exertion of work stress by all the sample was ‘very difficult’ while practicing the traditional method of cotton picking. However, it was ‘neutral’ for almost 70 per cent of the sample during the usage of hand operated cotton picker. There was a reduction in drudgery index in improved method (275.7+0.7) when compared to traditional method (276.2+0.5). The parameters related to physiological workload like resting, working and recovery heart rate, CCW, CCR etc., also showed positive changes by using improved cotton picking method. This study, through its results proved that increase in efficiency, drudgery reduction, saving time and effort of the labour can be done by adapting mechanization in farming activities. The results give an indication that taking up such small mechanization measures can surely help the farming community in a long run.

In Algeria and many other developing countries, many women do domestic work (weaving, cleaning, washing, ironing, cooking, caring, children the elderly, and persons with disabilities, etc.) in their homes. From domestic work, we refer to carpet weaving. This work is done in most Algerian cities. It is a job that women do at home. They do it while sitting for hours. Researchers show that domestic work require great effort. In addition, it is tiring and strenuous and may have negative effects on body. In this research, the focus will be on carpet weaving in the Southwestern Algeria (the Fatis carpet). Fatis carpet is named after the Fatis Palace (town), located in Tinrkuk area, in the province of Timimoun. (Algeria).This research, aims is to answer the following questions:1.What is the posture adopted while weaving the Fatis carpet?2.What are the body parts where may feel pain at work?3.Are there differences between the highly experienced (10 years and more) and the less experienced (05 years and less) knitters?Method: Researchers used the descriptive survey method, where they observe the Fatis woman as she makes the carpet, and after observing her for a sufficient period, she is presented with a set of questions (the PLIBEL questionnaire) to answer. The sample was (12) women with a mean age of 32.83 years, and an SD of 10.83 years. Tools: Data was collected through observation and PLIBEL Form (questionnaire).Results: This research aims to answer the following questions:1.What is the posture adopted while weaving the Fatis carpet? It has been found that women adopt the sitting crossed-legged working posture while knitting the carpet. The majority of women sit in the workstation for hours. They change it when they leave the work. 2.What are the body parts where may feel pain at work? It has been found that all parts of the body specified in the PLIBEL form (neck/shoulders and upper part of back; Elbows, forearms, and hands; feet; knees and hips; low back) are affected. However, the extent of the impact varied. The knees and hips were affected more than the rest of the other regions.3.Are there differences between the highly experienced (10 years and more) and the less experienced (05 years and less) knitters? It turns out that those with less experience suffer less than those with more experience.Discussion: The results will be discussed in light of the principles of cultural ergonomics. In various situations, it is necessary to resolve the contradiction that appears between the principles of ergonomics and what people are accustomed to and what they carry in terms of social trends by virtue of the societies and cultures to which they belong.Conclusion: This research shed light on the work of women in the textile industry. It was found that women adopt a work posture that needs discussion. It is a research that contributes to the development of social and cultural ergonomics

Published: July 2023

As the civilization of modern society continues to develop at a high rate, women in the new era have begun to gradually realize the importance of scientific training in shaping a perfect posture. If Ergonomics is applied to body training, the human body structure and physiological and psychological characteristics can be fully understood. he training movements can be precisely matched to the body size, physiological structure and physical characteristics of individual women so that the training process can be more rationalized and the results maximized within the physiological tolerance of women. By combining the scientific theories of anthropometry, human anatomy and exercise physiology, this paper analyzes the cooperative and coordinated relationship between the normative and mechanical aesthetics of local movement training of women's shoulders, waist and abdomen, and legs. Through the comparison of experimental data, it reflects that the scientific combination of aerobic exercises, muscle training, and flexibility training can not only correct women's bad body deformities and optimize their physical posture but also fully satisfy women's physiological and psychological multiple feelings and even provide some experience and references for better-promoting women's health and scientific body training.In this experiment, 100 female students from the Dalian Polytechnic University modeling program were selected for the study and trained for 5 months. Moreover, the experiment analyzed the specific changes in the students' body structure and aimed to provide a practical and feasible method and theoretical basis for scientific body training.

Wildland firefighters (WFF) face a set of specific work-related factors that directly affect their physical and cognitive abilities and compromise their health and safety. The working conditions include hard physical work and environmental conditions that combine high temperatures and high radiant heat. Such environments make using personal protective equipment (PPE) mandatory to protect them from risks. This fact restricts heat removal and adds extra weight, increasing thermal strain and the risk of heat-related illnesses on WFF. Since the number of females WFF has increased, it is necessary to study the repercussions of heat stress on this group. To date, it is not yet well-known whether sex-related differences in thermoregulation will be relevant when the individuals are wearing PPE and performing high physical effort in a hot environment. Therefore, we aimed to investigate the physiological response when performing moderate to high-intensity effort in a hot-dry environment while wearing PPE according to sex. Twenty WFF 10 females [23.9 ± 3.2 yr, 163.8 ± 3.4 cm and 62.7 ± 9.1 kg] and 10 males [31.9 ± 6.6 yr, 178.8 ± 5.8 cm and 73.9 ± 7.7 kg]) performed a 125 min treadmill test in a controlled ambient (30 ºC and 30% relative humidity). The protocol consisted of two exercise stages where WFF performed different continuous and variable exercise bouts in order to mimic the effort performed during real deployments. Participants wore the full standard PPE during the test. Oxygen uptake (VO2), heart rate (HR), core temperature (CT) and chest temperature (SkT) were monitored throughout the test. HR and CT were used to calculate the physiological strain index (PSI). Differences in body mass pre-post trials corrected for fluid intake were used to calculate sweat production (SwP), sweating rate (SwR), and evaporative efficiency (EE). Differences (p < 0.05) between females and males were found in %VO2max (62.5 ± 7.4 vs 55.3 ± 5.), HR (155 ± 10 vs 134 ± 14 beats·min–1), % of maximal HR (81.3 ± 3.5 vs 42.3 ± 6.5), CT (38.0 ± 10 vs 37.7 ± 0.33 ºC), SkT (36.0 ± 0.6 vs 35.3 ± 0.6 ºC) and PSI (4.1 ± 0.5 vs 3.5 ± 0.6). Even though SwR was higher (p < 0.05) for male participants (1001.5 ± 268.3 ml) compared to females (647.5 ± 145.9 ml), females had higher EE (32.9 ± 4.6 vs 16.7 ± 6.2 %). In conclusion, performing high-intensity exercise in hot-dry conditions while wearing PPE leads to a higher thermal and cardiovascular load for female WFF, making them more susceptible to heat illness. These results could be linked to lower aerobic fitness, sweating rate, and hormonal aspects that increased the thermal burden.
Development of an Automated Microclimate Adjustment System based on Concentration Levels of Students

Published: July 2023

The microclimate of a classroom can significantly impact the students' concentration. As students ourselves, we have noticed this. For the same subject, we are concentrated in one period, then in another, we lose our attention very easily. This prompted us to investigate the relationship between students' concentration levels in relation to the microclimate. Through machine learning, specifically through facial recognition and computer vision, we aimed to investigate the students' concentration levels based on the number of blinks per minute. While researching ways to analyse concentration levels, we found multiple studies which found a correlation between blink frequency and concentration level. We found that when people are concentrated, they tend to blink less and vice versa. The relationship between microclimate climate and concentration was analysed by measuring the blinks per minute while changing the microclimate at the same time. The microclimate conditions were varied using an air conditioner where the temperature set varied from 19°C to 31°C. The microclimate was measured using the NodeMCU microcontroller board paired with SCD-30 and HM-3301 sensors from Grove. This allowed us to gather data such as temperature, relative humidity, carbon dioxide concentration, PM2.5 and PM10 readings. From this, it was found that the most significant microclimate condition that affects concentration levels is carbon dioxide concentration. As the concentration of carbon dioxide increases, the concentration of the participants decreases. The observed trend is supported by various studies as well. Simultaneously, as the microclimate conditions were being varied, we sent out a survey to find the thermal comfort level of the students, allowing us to gauge how they felt according to the environment. Thermal comfort is when a person feels comfortable with the thermal environment. Participants were tasked to do their work for a fixed duration while a sensor recorded the temperature and relative humidity of the place. For every hour, the participants were required to rank their thermal comfort by using the ASHRAE scale. This survey identified the comfort zone at an upper limit temperature of 28.9°C and relative humidity of 68.0% and a lower limit temperature of 26.2°C and relative humidity of 83.1%. With these findings, we created an automated system to alter microclimate conditions. The place will be a conducive environment for the students based on their concentration and the environmental data obtained from the sensors. The alteration of microclimate conditions was done by controlling the air conditioner using an infrared LED module connected to the NodeMCU that sent out the infrared codes according to the conditions of the room, allowing us to adjust the microclimate efficiently while fully utilising the various modes of the air conditioning system to save energy.

In this paper, we propose a new interconnection network topology, hierarchical hyper-star network HHS(Cn,Cn) is based on hyper-star network. Hierarchical networks based on hypercube have been previously proposed; it has been shown that these networks are superior to the basic networks, in terms of various performance including diameter, network cost, fault tolerance etc. Our results show that the proposed hierarchical hyper-star network performs very competitively in comparison to hyper-star network, HCN(n,n), and HFN(n,n) have been previously proposed. We also investigate a various topological properties of the hierarchical hyper-star network HHS(Cn,Cn) including routing algorithm, diameter, connectivity, broadcasting.

Background: Acceptance and Commitment Therapy is characterized by emphasizing dispassionate detachment from one’s own thoughts. Cognitive Fusion is a state where people react to their thoughts literally, allowing them to take control and determine behavior. The aim of the study was to evaluate the psychometric properties of the Cognitive Fusion Questionnaire (CFQ) in clinical and non-clinical Mexican populations.Method: 525 subjects were registered in the non-clinical group and 570 in the clinical one; informed consent was obtained from each participant. Experiential avoidance (AAQ) and mindfulness (MAAS) were also evaluated. Results: All the items obtained an excellent discriminative power. The unifactorial model proposed in the original version was corroborated. Cronbach’s alphas considered excellent were obtained. It was not possible to establish test-retest temporal stability, and the difference in the scores of the non-clinical group was significant. Positive correlations were found between CFQ and AAQ scores, and negative correlations were found between CFQ and MAAS. The clinical group obtained higher scores on the CFQ.Conclusions: The CFQ is a valid and reliable instrument to be used in the Mexican population of a clinical and non-clinical nature.
Conductas sexuales de riesgo y búsqueda consciente de infección por VIH/SIDA (bug-chasing): una revisión narrativa desde la Psicología
Authors: Romero-Palau Mario , Cuenca-Martínez Ferran
Published: July 2023

Las conductas sexuales de riesgo han sido estudiadas con mayor frecuencia en los últimos años. El término barebacking hace referencia al sexo anal sin protección referido a hombres que mantienen relaciones sexuales con otros hombres, aunque el término se ha hecho extensible al sexo sin protección en general, incluyendo también a mujeres. Dentro de los barebackers, hay una población de hombres denominados bug-chasers. La práctica del bug-chasing hace referencia a la búsqueda activa y consciente de infección por el virus de inmunodeficiencia humana (VIH). Las personas seropositivas que transmiten el virus reciben el nombre de give-givers (“entregadores del regalo”). La presente revisión narrativa tuvo como objetivo principal conceptualizar y caracterizar estas poblaciones centrándose, además, en la evaluación de las principales teorías motivacionales que intentan explicar el fenómeno del bug-chasing. Un objetivo secundario fue analizar el papel de algunas variables de interés tales como la adicción al sexo, la auto-humillación, las preferencias de prácticas sexuales, preferencias de búsqueda de pareja, abuso de sustancias, la autoidentificación o los roles sexuales en bug-chasers y su comparación con barebackers y give-givers. Se necesita mayor investigación para dar respuestas a distintos interrogantes todavía presentes en el actual estado de la cuestión.

Introducción: La población mundial enfrenta el incremento de adultos mayores (AM) que crece de forma acelerada. Esto plantea oportunidades y desafíos dado que aumentará la demanda de atención médica y cuidados a largo plazo por la presencia de las enfermedades crónicas degenerativas y los síndromes geriátricos; además el AM experimenta eventos que pueden ser críticos y estresantes que pueden afectar su bienestar psicológico y social. Un factor que ha demostrado apoyar al individuo a enfrentar el estrés y se ha asociado con el bienestar es el sentido de coherencia. Objetivo: Conocer la relación y el efecto entre el sentido de coherencia y el bienestar psicológico y social en los AM del norte de México.Metodología: Estudio descriptivo correlacional con muestreo probabilístico proporcional al tamaño del estrato. Resultados: con una muestra integrada en un 77’3% por mujeres, el sentido de coherencia fue predictor positivo del bienestar psicológico (β = 0’45, p = 0’001) y social (β = 0’38, p = 0’001) en los AM.Conclusiones: El sentido de coherencia puede ayudar al AM a comprender, manejar y dar significado a los eventos que experimenta, a percibir su entorno como menos amenazador y alcanzar o mantener el bienestar psicológico y social.

Diversos organismos recomiendan a las y los profesionales de salud superar las propias creencias sexistas y apuntan a la importancia de abordar la desigualdad de género. En este sentido, este trabajo se centra en: (1) conocer los niveles de sexismo ambivalente en profesionales de salud mental, (2) analizar la asociación entre sexismo y características sociodemográficas y de perspectiva de género y (3) estudiar la asociación entre sexismo y detección de desigualdad de género en consulta. 449 profesionales de salud mental completaron la Escala de Sexismo Ambivalente, así como otro cuestionario desarrollado ad-hoc. Se realizaron análisis no paramétricos. Los datos mostraron, entre otros aspectos, un nivel bajo de sexismo en la muestra, así como que las y los profesionales que manifestaron niveles significativamente más bajos de sexismo, detectaron más problemas de desigualdad en consulta. Los resultados subrayan la importancia de reducir el sexismo de las y los profesionales para identificar los problemas de desigualdad de género.
