Published: July 2024

The hippocampus is important for learning tasks, such as conditioned place preference (CPP), which is widely used as a model for studying the reinforcing effects of drugs with dependence liability. Long-term opiate use may produce maladaptive plasticity in the brain structures involved in learning and memory, such as the hippocampus. We investigated the phenomenon of conditioning with morphine on the cell density of female rat hippocampus. Forty-eight female Wistar rats weighing on average 200–250 g were used. Rats were distributed into eight groups. Experimental groups received morphine daily (three days) at different doses (2.5, 5, 7.5 mg/kg) and the control-saline group received normal saline (1 ml/kg), and then the CPP test was performed. Three sham groups received only different doses (2.5, 5, 7.5 mg/kg) of morphine without CPP test. Forty-eight hours after behavioural testing animals were decapitated under chloroform anaesthesia and their brains were fixed, and after tissue processing, slices were stained with cresyl violet for neurons and phosphotungstic acid haematoxylin for astrocytes. The maximum response was obtained with 5 mg/kg of morphine. The density of neurons in CA1 and CA3 areas of hippocampus after injection of morphine and CPP was decreased. The number of astrocytes in different areas of hippocampus was increased after injection of morphine and CPP. It seems that the effective dose was 5 mg/kg, as it led to the CPP. We concluded that both injection of morphine and CPP can decrease the density of neurons and also increase the number of astrocytes in the rat hippocampus.

The aim of the study is to test the hypothesis that plants or flowers exhibiting Fibonacci sequences with larger numbers possess greater aesthetic beauty. As the number of Fibonacci sequences increases, the difference between Fn/Fn-1 and (1+√5)/2 decreases, tending towards zero. Consequently, a greater number of Fibonacci sequences brings the measurement closer to the Golden Ratio. The Golden Ratio serves as a tool for accurately assessing the beauty of objects, things, or living beings as perceived by human eyes. Based on this evidence, we formulated the hypothesis that plants or flowers with a higher number of Fibonacci sequences exhibit greater beauty. This hypothesis was tested through an interdisciplinary literature review and qualitative survey.The study reveals that discerning the beauty of plants or flowers involves a multitude of factors, including their shape, color, size, arrangement of petals or leaves, proportion, and quantity. Since generally no single factor determines the entire beauty of a plant or a flower, in specific cases, one factor may be the determinant. Thus, the hypothesis can be applied in specific cases, transforming it into a valid hypothesis. It posits that when analyzing the beauty of a particular kind of flower petals or leaves of plants with the same shape, color, and petals or leaves arrangement, the main factor contributing to its beauty is the presence of larger Fibonacci sequences.

Drying is a unitary operation that involves the simultaneous transfer of heat and humidity to reduce the water content of products to a safe level. This work therefore aims to study the characteristics of drying in an oven through the effect of temperature and drying time on Ocimum basilicum leaves harvested at different stages of maturity and to adapt the drying data into ten mathematical models to determine which one is best validated by experimental data. The leaves studied were collected at well-defined time intervals corresponding to the level of growth or maturity of the plants, i.e. one month, two months and three months. Drying was carried out using a natural convection oven at temperatures of 70, 80 and 90 °C. The water content varied from 80 to 86% depending on the age of the leaves. The drying speed was rapid at the beginning of the process and decreased after 60 min. The coefficient of determination and chi-square were used as statistical parameters for comparing the accuracy of the models. The Wang and Sing and Exponential models gave a better fit and better validated the experimental data compared to the other models whatever the temperature and age of the leaves.

The exploitation of marshy lowlands for agricultural purposes in African cities, with a clear predominance of market gardening, calls for concern about the availability of exploitation sites and the doubtful quality of the water used. This situation, particularly in urban areas, prompts farmers to look for alternative solutions, like hydroponics, a growing technique that does not only rationalizes the use of space, but saves water and mineral fertilizers, and simplifies growing techniques, but above all eliminates soil-related problems and increases yields. The aim of this research is to use treated sewage in hydroponics for tomato production in urban agriculture in the city of Yaoundé. The experiments were conducted in a completely randomized bloc design system with three replications. The effluents were obtained from the Messa domestic sewage treatment plant. Five treatments including raw effluent (T1); 50% diluted effluent (T2); 75% diluted effluent (T3); Maxigro 10-5-14 chemical fertilizer solution at a dose of 100 g per 50 l of tap water (positive control) (T4), and tap water (negative control) (T5) were applied to the tomatoes. The growth parameters considered plant height, leave number, and number of fruits. Lycopene, protein, phenol, and flavonoid content were also evaluated. The results show that 75% diluted effluent (T3) significantly (P<0.05) improved tomato growth, with values of 24±0.60 cm for plant height, 24.16±0.074 for leave number, and 72±6 for number of fruits compared with the negative control. However, the raw effluent (T1) and the 50% diluted effluent (T2), significantly improved the organo-mineral quality of the tomatoes (P<0.05) with 2.05±0.50 µg/g and 1.74±0.11 µg/g for lycopenes, 0.14 ±0.04µg/100g and 0.21±0.011 µg/100g for proteins, 5.73±0.25 µg/100g and 6.32±0.35 µg/100g for phenols, and 21.41±3.09 µg/100g and 29.08 ±2.27µg/100g for flavonoids respectively) compared to the negative control. The highest yield was obtained with the positive control (T4), followed by treatment (T3); with estimated fruit number of 34±3 and 27±2 fruits/m2 respectively. The reuse of treated wastewater in hydroponics would be an innovative technique that would alleviate the current problems of urban agriculture in the city of Yaoundé.

The intensive development of illegal gold mining, with the uncontrolled use of chemicals, has a strong impact on the environment in Côte d'Ivoire. This study aims to clean up contaminated water from the illegal gold mining site of Angamankro in the Daoukro department using two clays from Ivory Coast. To achieve this goal, physicochemical parameters such as pH, conductivity, turbidity and metal contents in water were measured. The levels of most of the metals studied in wastewater are higher than their various limit values recommended by the WHO. In order to depollute the water, adsorption treatment on Bingerville (BIN) and Katiola (KAT) clays were used. The treatment of wastewater with clays showed a significant reduction in metal contents. The elimination of different metals in water has decreased in the direction Cu >Hg > Zn> Mn > Ni > Co > Cd > Cr > As > Pb. KAT clay adsorbs metals better than BIN clay. This greater adsorption capacity that KAT clay possesses is due to its mineralogical composition (20.14% smectite) and its greater surface properties.

A Vestibular Challenge Combined with Calcitonin Gene-Related Peptide (CGRP) Promotes Anxiety-Like Behaviors
Authors: Rahman Shafaqat M. , Hauser Catherine , Faucher Stefanie , Fine Elana , Luebke Anne E.
Published: July 2024

Motion-induced anxiety and agoraphobia are more frequent symptoms in patients with vestibular migraine (VM) than migraine without vertigo. The neuropeptide calcitonin gene-related peptide (CGRP) is a therapeutic target for migraine and VM, but the link between motion hypersensitivity, anxiety, and CGRP is relatively unexplored, especially in preclinical mouse models. To further examine this link, we tested the effects of systemic CGRP and off-vertical axis rotation (OVAR) on elevated plus maze (EPM) and rotarod performance in male and female C57BL/6J mice. Rotarod ability was assessed using two different dowel diameters: mouse dowel (r = 1.5 cm) versus rat dowel (r = 3.5 cm). EPM results indicate that CGRP alone or OVAR alone did not increase anxiety indices. However, the combination of CGRP and OVAR did elicit anxiety-like behavior. On the rotarod, CGRP reduced performance in both sexes on a mouse dowel but had no effect on a rat dowel, whereas OVAR had a significant effect on the rat dowel. These results suggest that only the combination of CGRP with vestibular stimulation induces anxiety-like behavior and that CGRP affects the dynamic balance function in mice depending on the type of challenge presented. These findings suggest that anxiety-like behaviors can be teased out from imbalance behaviors in a mouse model of “migraine.” Future studies are aimed to determine if CGRP receptor antagonists that have been effective treating migraineurs and mouse “migraine” models may also reduce the anxiety observed in migraine.

Published: July 2024

Upotreba plodova uljane palme (Elaeis guineensis) za proizvodnju ulja od plodova palme seže unatrag nekoliko tisuća godina. Na temperaturi 18 – 20 °C ulje je u krutom stanju, pa se naziva i mast. Ulje ima specifičan kemijski sastav, fizikalna i morfološka svojstva. Preradom plodova uljane palme dobiva se ulje dobre kvalitete, koje se upotrebljava u raznim industrijama, a najveću primjenu ima u prehrambenoj industriji. Međutim, kvaliteta palmina ulja uvjetovana je načinom proizvodnje, uvjetima čuvanja i skladištenja. Čuvanje ulja na visokim temperaturama, izloženost svjetlu i kisiku dovodi do nepoželjnih promjena koje narušavaju kvalitetu ulja ili proizvoda koji ga sadrži. Da bi se postigla veća oksidativna stabilnost palmina ulja, dodaju se antioksidansi u određenim koncentracijama koji mogu biti prirodni ili sintetski. U svrhu ovog istraživanja od prirodnih antioksidansa upotrijebljeni su ekstrakti ružmarina, rujevine, đumbira, smilja, sikavice, kadulje i ekstrakt mješavine ljekovitih biljaka u koncentracijama od 0,20 %, dok su od sintetskih antioksidansa upotrijebljeni butilhidroksianisol, butilhidroksitoluen i propil galat u koncentracijama od 0,01 %. Provedene su analize udjela vode, slobodnih masnih kiselina i vrijednosti peroksidnog broja, na kontrolnom uzorku (bez dodatka antioksidansa). Nakon dodatka antioksidansa u palmino ulje proveden je test održivosti u sušioniku pri 63 °C i svaka 24 h izvršeno uzorkovanje uz određivanje vrijednosti peroksidnog broja i sadržaja slobodnih masnih kiselina do najviše 120 h. Provedenim istraživanjem utvrđeno je da iz grupe sintetskih antioksidansa najveći doprinos stabilnosti palmina ulja pokazao je butilhidroksitoluen, dok su ostali sintetski antioksidansi slično djelovali. Iz grupe prirodnih antioksidansa najbolji učinak imao je ekstrakt smilja, dok su ekstrakti kadulje i sikavice ubrzali oksidativno kvarenje palmine masti.

Authors: Ćosić Ivana , Matijević Bojan
Published: July 2024

Pivo se smatra relativno stabilnim proizvodom s obzirom na mikrobno kvarenje. Kemijski sastav piva ne pogoduje rastu većine mikroorganizama, što je povezano s niskom pH-vrijednosti i niskim udjelom fermentabilnih ugljikohidrata te sadržajem alkohola, sastojcima hmelja i anareobnim uvjetima koje osigurava nastali CO2. Međutim, određene bakterijske vrste mogu rasti u pivu, izazivajući promjene u fizikalno-kemijskim i senzorskim svojstvima proizvoda, čime ga čine neprihvatljivim za konzumaciju. Rast bakterija u pivu očituje se povećanjem biomase i pojavom mutnoće, a kod izraženijeg kvarenja i nastajanjem taloga. Mikrobna populacija u pivovari mijenja se tijekom tehnološkog procesa proizvodnje. Posebno štetni kontaminanti za proizvodnju piva su bakterije iz rodova Lactobacillus, Pediococcus, Pectinatus i Megasphaera. S ciljem smanjenja rizika na najmanju moguću razinu, svi industrijski pogoni, bilo da je riječ o velikim industrijama ili malim (craft) pivovarama, moraju biti u mogućnosti brzo detektirati i identificirati mikrobne kontaminante tijekom cijelog tehnološkog procesa. Mikrobiološka analiza tijekom procesa proizvodnje, punjenja i pakiranja proizvoda ima važnu ulogu u osiguranju kvalitete i zdravstvene ispravnosti proizvoda za konzumaciju. U tu svrhu pivovare provode mikrobiološku analizu uzoraka primjenjujući tradicionalne, ali i suvremene metode detekcije i identifikacije. Kroz ovaj pregledni članak istražuje se utjecaj mikrobne kontaminacije piva na fizikalno-kemijska i senzorska svojstva proizvoda te se prikazuju izazovi s kojima se pivovare suočavaju da bi osigurale mikrobiološku ispravnost proizvoda s ciljem osiguranja kvalitete i sigurnosti proizvoda te sprječavanja proizvodnih i financijskih gubitaka.

There is no one-size-fits-all method of teaching and learning, as blended learning instruction may demonstrate. The aim of this research was to examine the effects of blended learning (BL) on university students' reading comprehension. The study involved 45 first-year university students, with 23 in the experimental group and 22 in the control group, utilizing a quasi-experimental design with a quantitative approach. Data were gathered through pre-posttest reading comprehension exams adapted from the TOEFL (2023). Following the pretest, the experimental group received blended learning instruction via Moodle, engaging in 16 weeks of intervention over three hours per week. Reading passages and activities were adapted from Communicative English Skills I materials and integrated into the Moodle platform with e-learning elements. Data analysis employed mean calculations, independent samples t-tests, paired samples t-tests, and effect size measures. The pretest revealed no statistically significant differences in overall reading comprehension between the two groups (t =.797, p =.430). However, in the post-test, the experimental group achieved an average mean score of 87.2, whereas the control group averaged 77.6. Significant differences emerged between the groups (t = 3.904, p =.000). The study demonstrated that the experimental group showed statistically significant differences in reading comprehension across all categories compared to the control group. Future research could explore blended learning's influence on other English language skills and its effects across various grade levels, providing valuable insights for English language educators and curriculum developers seeking to integrate blended learning approaches into their programs.
REPRODUCTIVE AGEING: Altered histone modification landscapes underpin defects in uterine stromal cell decidualization in aging females
Authors: Woods Laura , Dean Wendy , Hemberger Myriam
Published: July 2024

In Brief

Advanced maternal age is associated with a higher rate of pregnancy complications that are unrelated to karyotypic abnormalities of the oocyte. This study shows that the murine uterine stroma undergoes profound epigenetic changes affecting active and repressive histone modification profiles that are associated with impaired endometrial functionality and underpin the decline in reproductive performance of aged females.

Decidualization describes the transformation of the uterine stroma in response to an implanting embryo, a process critical for supporting the development of the early embryo, for ensuring normal placentation and ultimately for a healthy reproductive outcome. Maternal age has been found to impede the progression of decidualization, heightening the risk of reproductive problems. Here, we set out to comprehensively characterize this deficit by pursuing transcriptomic and epigenomic profiling approaches specifically in the uterine stromal cell (UtSC) compartment of young and aged female mice. We find that UtSCs from aged females are globally far less responsive to the decidualization stimulus triggered by exposure to the steroid hormones estrogen and progesterone. Despite an overall transcriptional hyperactivation of genes that are differentially expressed as a function of maternal age, the hormonally regulated genes specifically fail to be activated in aged UtSCs. Moreover, even in their unstimulated ‘ground’ state, UtSCs from aged females are epigenetically distinct, as determined by genomic enrichment profiling for the active and repressive histone marks H3K4me3 and H3K9me3, respectively. We find that many hormone-inducible genes exhibit a profound lack of promoter-associated H3K4me3 in aged UtSCs, implying that a significant enrichment of active histone marks prior to gene stimulation is required to enable the elicitation of a rapid transcriptional response. With this combination of criteria, our data highlight specific deficits in epigenetic marking and gene expression of ion channels and vascular markers. These results point to fundamental defects in muscle-related and perivascular niche functions of the uterine stroma with advanced maternal age.

С целью разработки каталитической технологии переработки угольного метана в водородсодержащий газ проведен термодинамический анализ реакции три-риформинга метана (ТРМ) и исследовано влияние температуры (600–850 °С), времени контакта (0.04–0.15 с), линейной скорости подачи реагентов (80–240 см/мин) и состава реакционной смеси (CH4 / CO2 / H2O / O2 / He = 1 : (0.3–0.5) : (0.2–0.5) : (0.1–0.3) : (2.9–3.2)) на конверсию исходных реагентов и выход целевых продуктов в процессе ТРМ с использованием нанесенного Ni-содержащего катализатора. Отмечено, что с увеличением температуры реакции ТРМ от 600 до 850 °С показатели процесса возрастают (конверсия метана – 36 → 94 %, конверсия углекислого газа – 57 → 97 %, выход водорода – 37 → 91 %, выход монооксида углерода – 44 → 94 %, молярное соотношение H2/CO – 1.5 → 1.7) и при температуре 850 °С сопоставимы с равновесными значениями. Установлено, что варьирование значения O/C и состава окислителей позволяет регулировать показатели процесса ТРМ. Определены оптимальные условия процесса ТРМ для достижения максимальной эффективности каталитической переработки угольного метана в водородсодержащий газ: температура – в диапазоне 800–850 °С, время контакта – 0.15 с, линейная скорость – 160 см/мин и молярное соотношение реагентов в сырье – CH4 / CO2/ H2O / O2 = 1 : 0.5 : 0.2 : 0.25.

In order to develop a catalytic technology for processing coal mine methane into hydrogen-containing gas, thermodynamic analysis of methane tri-reforming (TRM) was carried out, and the influence of temperature (600–850 °C), contact time (0.04–0.15 s), linear feed rate (80–240 cm/min) and composition (CH4/ CO2/ H2O / O2 / He = 1: (0.3–0.5) : (0.2–0.5) : (0.1–0.3) : (2.9–3.2)) of the reaction mixture on the conversion of the initial reagents and target products in the TRM process in the presence of a supported Ni catalyst was studied. It has been shown that with an increase in the temperature of the TRM reaction from 600 to 800 °C the process performance improves (methane conversion: 36 → 94 %, carbon dioxide conversion: 57 → 97 %, hydrogen yield: 37→ 91 %, carbon monoxide yield: 44→ 94 %, molar ratio H2/CO: 1.5 → 1.7), and at a reaction temperature of 850 °C the process indicators are close to equilibrium values. It has been established that varying the O/C value and the composition of oxidants makes it possible to regulate the performance of TRM process. The optimal conditions for the TRM process were identified to achieve maximum efficiency of the catalytic processing of coal mine methane into hydrogen-containing gas: temperature – in the range of 800–850 °C, contact time – 0.15 s, linear feed rate – 160 cm/min and molar ratio of reagents in the initial feed – CH4/ CO2/ H2O / O2 = 1: 0.5 : 0.2 : 0.25.

Published: July 2024

Radiography is a crucial diagnostic imaging modality in clinical practice, with persistent challenges in digital radiography regarding the level of exposure. The International Electrotechnical Commission standardized the Exposure Index (EI) and Deviation Index (DI) in digital systems, aiming to improve the assessment of radiation exposure. Each exam has an associated Target Exposure Index (EIT), representing the balance between radiation dose and image quality. This study analyzed the EI and DI of digital radiographs at a university hospital, using a database of 71,760 radiographs. The analysis considered the action limits as suggested by the American Association of Physicists in Medicine (AAPM). The group of exposures carried out in radiography rooms presented a DI of 1.2, while that of exposures carried out on mobile equipment, 2.4. In contrast, the first group presented standard deviation values between 1.5 and 3.9, while the second, between 1.8 and 2.6. These results suggest that exposures performed using Automatic Exposure Control (CAE) differ less from EIT, however, radiographic techniques were more standardized among exams with mobile equipment, performed with manual selection of exposure parameters, as these exams presented a smaller DI dispersion range. The creation of an automated tool in Google Looker Studio facilitated interactive data analysis, presenting information by anatomical region and view, with the potential to continuously monitor radiological practices. For certain incidences, the average DI values obtained differed substantially from the ideal value, which requires optimization actions, investigation into the definition of adequate EIT and calibration of the CAE. The study provided a detailed overview of local radiographic practices, highlighting priorities for optimization and standardization actions.

Psychogenic non-epileptic seizure-an entity on the borderzones of neurology, psychiatry and clinical psychology: a case report with review of literature
Authors: K Sethi Nitin , Sethi Lehar , Rawat Riddhi , Batra Deepta
Published: July 2024

Psychogenic Non-Epileptic Seizures (PNES) are a commonly encountered neurological entity, often misdiagnosed due to their resemblance to epileptic seizures. PNES episodes mimic epileptic seizures but stem from psychological factors, making accurate diagnosis essential for effective treatment. They are now included under the umbrella of Functional Neurological Disorders (FND). We report a case of PNES and review the medical literature with respect to the incidence and prevalence of this entity in the Indian population. Our case report highlights the complexities of PNES diagnosis- a disorder on the "border zone" between neurology, psychiatry, and psychology. A multidisciplinary approach involving neurologists, psychiatrists, and psychologists is crucial for effective PNES management in India, overcoming the stigma associated with this condition and improving patient outcomes.

OBJECTIVES

Pediatric diabetic ketoacidosis (DKA) is often treated in a PICU, but nonsevere DKA may not necessitate PICU admission. At our institution, nonsevere DKA was treated on the floor until policy change shifted care to the PICU. We describe outcomes in pediatric mild to moderate DKA by treatment location.

METHODS

Patients aged 2 to 21 with mild to moderate DKA (pH <7.3 but >7.1), treated on the floor from January 1, 2018 to July 31, 2020 and PICU from August 1, 2020 to October 1, 2022 were included. We performed a single-center, retrospective cohort study; primary outcome was DKA duration (from emergency department diagnosis to resolution), secondary outcomes included hospital length of stay, and complication rates, based on treatment location.

RESULTS

Seventy nine floor and 65 PICU encounters for mild to moderate pediatric DKA were analyzed. There were no differences in demographics, initial pH, or bicarbonate; PICU patients had more acute kidney injury on admission. Floor patients had a shorter DKA duration (10 hours [interquartile range 7–13] vs 11 hours [9–15]; P = .04), and a shorter median length of stay (median 43.5 hours [interquartile range 31–62] vs 49 hours [32–100]; P < .01). No patients had clinical signs of cerebral edema; other complications occurred at similar rates. PICU patients received significantly more intravenous electrolyte boluses, but there were no differences in dysrhythmia or electrolyte abnormalities on final serum chemistry.

CONCLUSIONS

Our study did not find a clear benefit to admitting patients with mild to moderate DKA to the PICU instead of the hospital floor. Our findings suggest that some children with nonsevere DKA may be treated safely in a non-PICU setting.

AbstractThis paper presents the results of a systematic literature review (SLR) of academic research related to service quality attributes in higher education institutions. The literature review is organised around two main objectives: identifying trends of studied topics and significant attributes in implementing service quality. A comprehensive search of relevant databases of published research from 2012 to 2022 was conducted to identify peer-reviewed articles that meet the criteria for inclusion in the review. The search yielded a total of 28 relevant studies, which were evaluated to address the study objectives. The SLR identified four clusters of topics within service quality: The importance of quality services, quality evaluation, the role of digital technology, and stakeholders’ retention. Finally, the derived attributes in this paper are expected to assist higher education institutions (HEIs) in developing countries, particularly in developing countries, in identifying areas of improvement in their service quality and making targeted adjustments to improve the overall experience of their stakeholders.Keywords: higher education institutions; service quality attributes; service experience; systematic literature review.---SažetakU ovam radu predstavljeni su rezultati sustavnoga pregleda literature (SPL) akademskih istraživanja povezanih s karakteristikama kvalitete usluga u visokoškolskim ustanovama. Pregledom literature nastoji se postići dva glavna cilja: identificirati trendove u temama koje se proučavaju te važne čimbenike koji utječu na poboljšanje kvalitete usluga. Provedena je sveobuhvatna pretraga relevantnih baza podataka objavljenih studija u razdoblju od 2012. do 2022. godine kako bi se identificirali recenzirani članci koji ispunjavaju kriterije za uključivanje u pregled. Pretragom je dobiveno ukupno 28 relevantnih studija koje su ocijenjene u skladu s ciljevima studije. SPL izvješće identificiralo je četiri skupine pitanja koja se odnose na kvalitetu usluga: važnost kvalitetnih usluga, procjena kvalitete, uloga digitalne tehnologije i zadržavanje dionika. Očekuje se da će obilježja navedena u ovome radu pomoći visokim učilištima (VU) u zemljama u razvoju - posebice u zemljama u razvoju, identificirati područja poboljšanja kvalitete usluga koje pružaju i izvršiti ciljane prilagodbe kako bi se poboljšalo cjelokupno iskustvo njihovih dionika.Ključne riječi: iskustvo usluge; obilježja kvalitete usluga; sustavni pregled literature; visoka učilišta.

Az újrakezdés bája: a Magyar Pszichológiai Társaság első konferenciái az újjáalakulás után
Authors: Pléh Csaba
Published: July 2024

Az 1960-as évek fordulója a magyar pszichológia újjáalakulásának és újrafazonozásának izgalmas korszaka volt. A dolgozat a közvetlen háttér bemutatásával indul. Hogyan lett az 1952 novemberében alakult és 1958-ban megszűnt Pavlov Bizottságnak utóda az MTA elnökségi Pszichológiai Bizottsága? Ez az MTA elnökségi maxi bizottság azután kiravaszkodta a pszichológiai társaság és a Szemle újraindulását. Milyen szerepe volt ebben az átalakulásban a nagyhatalmú orvosok és a kisszámú pszichológus rafináltságának és karrierkeresésének?

A Társaság első nagygyűlései seregszemlék voltak, nagy identitásformáló szereppel. Ennek egy különleges vonása volt a nemzetközi pszichológiai élet vezető szereplőinek, például Paul Fraisse és Henri Tajfel a kötelező szovjetek melletti megjelenése az MPT nagygyűlésein. Nyílt és rejtett üzeneteket hoztak. Ismét közénk tartoztok, a pszichológusok nagy nemzetközi családjába, és csináljatok nyugatosabb tudományt, olyat, amilyet régen tudtatok.

IDEOLOGI (DAN) ESTETIKA SENO GUMIRA AJIDARMA: SAKSI MATA DALAM RUANG PERJUMPAAN IDEOLOGIS
Authors: Arifin Moch Zainul
Published: July 2024

Tulisan ini mencoba menguraikan struktur ideologi Seno Gumira Ajidarma dalam Saksi Mata pada masa otoriter Orde Baru. Pisau analisis yang digunakan dalam penelitian ini adalah teori kritik sastra materialisme Terry Eagleton yang mengasumsikan bahwa teks sastra tidak bertindak pasif, tetapi bertindak aktif menentukan proses produksi dan struktur ideologi yang melingkupinya. Dengan demikian, kritik sastra Eagleton melihat karya sastra dari aspek eksternal dan juga aspek internalnya. Berangkat dari hal itu, bagaimana Saksi Mata menawarkan bentuk kritik yang, tentu ideologis, dihadirkan guna mengguncang kekuasaan absolut Orde Baru? Hasil penelitian menunjukkan bahwa, pertama, struktur ideologi dalam cerpen Saksi Mata meliputi prkatik material eksternal dan internal teks. Aspek eksternal teks merupakan hasil artikulasi dominasi Orde Baru. Untuk itu, Saksi Mata juga tidak luput dari pengaruh mobilisasi Soeharto, akan tetapi Seno dengan Saksi Mata mampu melawan kebijakan tersebut. Kedua, konstruksi internal teks yang sebetulnya ruang perjumpaan dan negosiasi ideologi-ideologi yang ada,  Saksi Mata berupaya menunjukkan kengerian totaliter Orde Baru. Akan tetapi, tentu dalam ruang politik yang represif, kritik dalam semangat kemanusiaan, keadilan dan kebebasan berpendapat ditransfor-masi dan dibungkus dalam cerpen Saksi Mata dengan bangunan satire dan khas komedi, sekaligus mengungkapkan kengeriannya.Kata Kunci: Struktur Ideologi, Estetika, Terry Eagleton

Dinamika kehidupan di era revolusi industri 4.0 menuntut kesiapan dari berbagi komponen untuk mengahdapinya. Salah satu kesiapannya adalah sikap mental atau etos kerja yang harus dimiliki oleh setiap orang atau sekelompok orang dari sebuah entitas. Penguasaan teknologi menjadi ciri utama dari era ini yang akan memengaruhi terhadap pola interaksi manusia. Berbagai aspek kehidupan akan ditentukan oleh alat-alat teknologi yang supercanggih, bahkan keberadaan manusia pun layaknya sebagai mesin saja. Dampaknya terjadi dehumanisasi, hakekat manusia mengalami disrupsi. Kenyataann ini, menimpa salah satu etnis, yaitu etnis sunda. Oleh karena itu, keberadaan Orang Sunda di era ini sangat ditentukan oleh etos kerja yang dilakukannya. Etos kerja ini sangat dipengaruhi oleh motivasi hidup yang diperankan oleh orang Sunda yang bersumberkan pada pandangan hidupnya. Aspek lain, ditentukan oleh keyakinan yang berkembang di tatar Sunda. Dua aspek inilah yang menenetukan etos kerja orang Sunda Meningkatnya kedua aspek tersebut ditetentukan pula oleh pola pendidikan yang dikembangkan oleh orang Sunda. Pola pendidikan yang bersifat menumbuhkan kesadaran menjadi tawaran bagi problem pendidikan dewasa ini. Selain itu, faktor yang mempengaruhi etos kerja orang sunda, ditentukan oleh aspek-aspek lainnya, yang sifatnya bukan kultur, seperti peraturan formal, ekonomi, dan gaya kepemimpinan yang harus dijadikan perhatian dalam meningkatkan etos kerja. Temuan faktor-faktor inilah yang melengkapi faktor faktor yang mempengaruhi terhadap etos kerja, sebagaimana diutarakan oleh Ajip Rosjidi.Kata Kunci: Revolusi industri 4.0, etos kerja, orang Sunda

This study discusses the Sahih Sahih Al-Bukhari At-Taudhih Li Syarhi Al-Jami Ash-Sahih Ibn Al-Mulaqin, using the historical approach and literature study (Research library). It was found that Syarah Ibn Al-Mulaqin was one of the very thick Sahih books of al-Bukhari, containing a lot of information, and was rich in approaches from various disciplines that were compiled for 22 years. The method used by Ibn Mulaqin is by explaining grammar, stretching the interrelationship of the subtitles with the title, then explaining the narrator and then discussing the contents of the hadith in detail, by explaining the history, the rijal of hadith, and Fiqh.
