Authors:   ,   Lebanese American University, Fadel Reem
Published: August 2022

This study yields a deeper understanding of the relationship between knowledge management and innovation in organizations along with insights into the importance of training. Hence, the primary aim of this study is to examine the relationship between knowledge management and innovation as moderated by the construct of training. While the constructs of knowledge acquisition, application, and protection, and behavior and strategic innovation are the cornerstones of this study, the Resource-Based View Theory is the theoretical framework. An online questionnaire was leveraged to gather data from respondents, In Lebanon and the Middle East region, for data collection purposes. The present research uses SPSS statistical software to investigate the relationship between the different constructs. Results indicated that knowledge acquisition, knowledge application and knowledge protection are significantly and positively related to the two dimensions of innovation: behavior innovation and strategic innovation. Also, results indicated a moderating effect of training in the relationship between knowledge acquisition and behavior innovation, and in the relationship between knowledge application and behavior innovation. Specifically, as levels of training increase, the effect of knowledge acquisition and knowledge application on behavior innovation decreases. On the other hand, this study indicated that training had no significant moderating effect in the relationship between knowledge protection and behavior innovation. Moreover, training has no significant moderating effect in the relationship between the three constructs of KM under study and strategic innovation. Overall, the study recommends that organizations who want to foster innovation should give considerable attention to their knowledge management processes of acquisition, application, and protection, even in the presence of training.

PEMANFAATAN TUMBUHAN SEBAGAI BAHAN PAKAN IKAN: SEBUAH REVIEW
Authors: Amelia Fadilah , Andriani Yuli , Haetami Kiki
Published: August 2022

Budidaya perikanan sangat dipengaruhi oleh ketersediaan pakan yang cukup dalam jumlah dan kualitasnya untuk mendukung hasil produksi yang maksimal. Pakan menjadi salah satu faktor yang berperan penting dalam keberhasilan kegiatan budidaya karena menentukan pertumbuhan dan perkembangan ikan serta pakan juga merupakan komponen biaya produksi yang paling tinggi yaitu karena bisa mencapai 75% dari biaya operasional. Hal ini disebabkan karena tingginya harga bahan baku pakan yang masih impor. Maka penggunaan pakan dalam budidaya perlu diefisienkan untuk dapat mengoptimalkan hasil produksi budidaya. Ada berbagai cara yang dapat dilakukan untuk menekan harga pakan guna mengurangi atau mengganti bahan baku, antara lain pemanfaatan tumbuhan sebagai bahan pakan ikan salah satunya adalah Lemna sp, Azolla sp, kiambang, eceng gondok, Indigofera Sp, dan sebagainya. Tumbuhan tersebut berpotensi digunakan sebagai bahan pakan ikan karena kandungan protein berkisar 27-35% dan terbukti berpengaruh terhadap peningkatan berat badan juga daya cerna sehingga dapat dijadikan sebagai pakan alternatif dan menjadi solusi dalam permasalahan biaya produksi budidaya.

(Re-)viewing the acquisition of rhythm in the light of L2 phonological theories
Authors: Sönning Lukas
Published: August 2022

Previous work on non-native speech rhythm has often drawn on L2 phonological theory for the interpretation of findings. The explicit confrontation of theory-derived hypotheses with data remains scarce, however. This paper illustrates how a hypothetico-deductive approach can contribute to our understanding of L2 speech rhythm. We consider cross-sectional data on prominence alternations in German learner speech from the viewpoint of two dynamic frameworks: The Ontogeny Phylogeny Model (OPM) and the Linguistic Theory of L2 Phonological Development (LTD). While both theories deal with L1-independent, universal forces in L2 acquisition, the OPM further considers the role of L1 transfer, similarity, and markedness. The predictions we formulate based on the two models lead us to pursue distinct methodological strategies. While our reading of the OPM prompts us to measure speech rhythm as a single, global category of speech, the LTD suggests a more nuanced, componential approach to L2 rhythm. Our application of the OPM confronts us squarely with the limited utility of rhythm metrics for L2 speech research and points to a number of issues at the theory-data interface. Overall, the LTD generates more informative predictions and provides a richer framework for the empirical study of prominence grading in L2 speech.
Survey on antimicrobial resistance knowledge and perceptions in university students reveals concerning trends on antibiotic use and procurement
Authors: Leal Helena Ferreira , Mamani Claudia , Quach Caroline , Bédard Emilie
Published: August 2022

BACKGROUND: The World Health Organization (WHO) has declared that antimicrobial resistance is one of the top ten global public health threats humanity is facing. To tackle this problem, it is necessary to not only address it in the hospital setting, but even more so in the community. In this context, understanding people’s knowledge, attitudes, and practices towards antimicrobial resistance is of utmost importance. Accordingly, we investigated whether students from the Université de Montréal (Quebec, Canada) had perceptions and behaviours that could foster bacterial resistance. METHODS: We conducted an observational, cross-sectional, prospective, and descriptive study from November 30 to December 11, 2020. We applied an online questionnaire (Google Forms) adapted from the WHO survey entitled ‘Antibiotic resistance: Multi-country public awareness survey.’ RESULTS: Overall, 106 participants were included in this study. Most of them demonstrated reasonable understanding and behaviours related to antimicrobial resistance. Erroneous response proportions ranged from 0.9% to 25.5%, except for the statement ‘Antibiotic resistance occurs when your body becomes resistant to antibiotics, and they no longer work,’ where 63.2% of participants answered that it was true, even though it is false. Regarding antibiotic use, 28.3% of participants said they already had used antibiotics without a doctor’s prescription. Of these, 55.2% were Canadian students. CONCLUSIONS: This study indicates a possible misuse of antimicrobials in an area where antibiotics should not be easily accessible without a prescription. It is necessary to investigate why these medications are being used without being prescribed. Furthermore, we demonstrate a need to increase public awareness to better understand antimicrobial resistance’s theoretical basis.
Mechanical Milling and Polishing of Cross Sections using a Micro CNC Machine for Failure Analysis
Authors: Pichumani Pradip Sairam , Khatkhatay Fauzia
Published: August 2022

In this article, the authors evaluate micro CNC milling as an alternative to manual parallel lapping for mechanical cross-sectioning of flip-chip packaged samples. They describe both processes, and how they compare to other cross-sectioning techniques, and clearly illustrate the differences. SEM images of a manually polished sample show process-induced cracking, chipping, and delamination at the die-C4 interface. In contrast, the CNC-milled sample is artifact-free and the C4 bumps are uniformly exposed along the entire length of the cross-section.

Published: August 2022

Objectif : Le taux de vacance de poste des médecins est estimé à 23 % dans les services d’urgence (SU). L’objectif de l’étude était d’identifier des facteurs d’attractivité potentiels des SU en France.

Méthodes : Cette étude est composée de deux enquêtes observationnelles transversales nationales. La première, adressée aux responsables de service, comparait les facteurs d’attractivité entre les SU à faible et forte vacance de poste. La seconde, réalisée auprès des médecins urgentistes, hiérarchisait par évaluation numérique (échelle de 1 à 10) l’attractivité des différents facteurs.

Résultats : Concernant l’enquête auprès des responsables de service, 76 SU ont été inclus : 47 à forte vacance de poste et 29 à faible vacance de poste. Le taux de vacance globale était de 23 %. En analyse univariée, les facteurs associés significativement à une faible vacance de poste étaient un nombre annuel de passages élevé (OR = 1,03 [1,01–1,06] pour 1 000 passages supplémentaires ; p = 0,03), un faible taux d’hospitalisation (OR = 0,93 [0,85–0,99] par pourcentage supplémentaire ; p = 0,04), la possibilité d’enseignement facultaire (OR = 3,07 [1,05–9,33] ; p = 0,02), le respect du temps de travail hebdomadaire (OR = 0,10 [0,01–0,54] si temps de travail ≥ 48 heures par rapport à 39 heures ; p = 0,02) et une bonne ambiance au sein du service (OR = 10,0 [2,12–74,5] si ambiance excellente par rapport à moyenne ; p = 0,02). Concernant l’enquête auprès des médecins urgentistes, 971 ont répondu. Les trois facteurs considérés comme les plus attractifs étaient l’ambiance au sein du service, la facilité d’aval et la présence d’un service de réanimation. La qualité de vie au travail était la thématique d’attractivité la plus importante pour les médecins urgentistes.

Conclusion : Les facteurs liés à la qualité de vie au travail et certaines caractéristiques hospitalières sont associés à une plus faible vacance de poste et qualifiés d’attractifs par les médecins urgentistes.
Low Xanthophylls, Retinol, Lycopene, and Tocopherols in Grey and White Matter of Brains with Alzheimer’s Disease
Authors: Dorey C. Kathleen , Gierhart Dennis , Fitch Karlotta A. , Crandell Ian , Craft Neal E.
Published: August 2022

Background:

Oxidative stress contributes to pathogenesis and progression of Alzheimer’s disease (AD). Higher levels of the dietary antioxidants— carotenoids and tocopherols— are associated with better cognitive functions and lower risk for AD, and lower levels of multiple carotenoids are found in serum and plasma of patients with AD. Although brains donated by individuals with mild cognitive impairment had significantly lower levels of lutein and beta-carotene, previous investigators found no significant difference in carotenoid levels of brains with AD and cognitively normal brains.

Objective:

This study tested the hypothesis that micronutrients are significantly lower in donor brains with AD than in healthy elderly brains.

Methods:

Samples of donor brains with confirmed AD or verified health were dissected into grey and white matter, extracted with organic solvents and analyzed by HPLC.

Results:

AD brains had significantly lower levels of lutein, zeaxanthin, anhydrolutein, retinol, lycopene, and alpha-tocopherol, and significantly increased levels of XMiAD, an unidentified xanthophyll metabolite. No meso-zeaxanthin was detected. The overlapping protective roles of xanthophylls, carotenes, α- and γ-tocopherol are discussed.

Conclusion:

Brains with AD had substantially lower concentrations of some, but not all, xanthophylls, carotenes, and tocopherols, and several-fold higher concentrations of an unidentified xanthophyll metabolite increased in AD (XMiAD).
Classification of microscopic cervical blood cells using inception ResNet V2 with modified activation function
Authors: Thai Pon L.T. , Merry Geisa J.
Published: August 2022

Cervical cancer is the most frequent and fatal malignancy among women worldwide. If this tumor is detected and treated early enough, the complications it causes can be minimized. Deep learning demonstrated significant promise when imposed on biomedical difficulties such as medical image processing and disease prognostication. Therefore, in this paper, an automatic cervical cell classification approach named IR-PapNet is developed based on Inception-ResNet which is an optimized version of Inception. The learning model’s conventional ReLu activation is replaced with the parametric-rectified linear unit (PReLu) to overcome the nullification of negative values and dying ReLu. Finally, the model loss function is minimized with the SGD optimization model by modifying the attributes of the neural network. Furthermore, we present a simple but efficient noise removal technique called 2D-Discrete Wavelet Transform (2D-DWT) algorithm for enhancing image quality. Experimental results show that this model can achieve a top-1 average identification accuracy of 99.8% on the pap smear cervical Herlev datasets, which verifies its satisfactory performance. The restructured Inception-ResNet network model can obtain significant improvements over most of the state-of-the-art models in 2-class classification, and it achieves a high learning rate without experiencing dead nodes.

Published: August 2022

BACKGROUND: Working in forced postures and standing continuously can be classified as straining the musculoskeletal system. OBJECTIVE: Since such postures are frequently used in hospital canteen kitchens, we used kinematic analysis to determine the working postures of canteen kitchen staff. METHODS: In this study, the daily work routine of 18 (11 w/7 m) workers of a hospital canteen kitchen (Frankfurt Main/Germany) aged 21–62 years (46±13 years) was examined by means of kinematic analysis (CULEA system; IFA; Sankt Augustin/Germany) and a detailed computerized analysis of the activities performed on-site. Angle values of the head and trunk were evaluated in accordance with ergonomic standards and presented using percentile values (P05-P95). The OWAS method was also employed to capture the proportions of standing, walking and sitting work. RESULTS: The kinematic posture analysis showed for all activities on the conveyor belt a tendency towards a dorsally inclined body position: trunk inclination (–7.5° to 0), thoracic spine inclination or a bending forward (–11.3° to 0°) and curvature of the back within the thoracic spine (–15.2° to 0°). In addition, >90% of the “activities on the belt” (46% of the daily working routine) were carried out standing. CONCLUSION: The activities on the conveyor belt were characterized by a tendency towards hyperextension of the trunk, possibly due to a too high working environment. Furthermore, an increased burden on body structures while standing can be concluded. From a primary prevention perspective, this increased standing load should be reduced by behavioral and relational prevention measures.

Published: August 2022

BACKGROUND: Slips, trips, and falls are the second leading cause of non-fatal injuries in workplace in the United States. A stage combat landing strategy is used in the theatre arts to reduce the risk of fall-induced injury, and may be a viable approach among some working populations. OBJECTIVE: The goal of this study was to compare fall impact characteristics between experts in stage combat landing strategy and naïve participants after four training sessions of stage combat landing strategy training. METHODS: Forward and backward falls from standing were induced by releasing participants from static leans. Participants fell onto a foam mat, and impact force was measured using force platforms under the mat. A statistical equivalence test was used to determine if impact characteristics between groups were similar. RESULTS: Results indicated equivalence between groups in peak impact force during backward but not forward falls. Equivalence between groups in impact time suggested a mechanism by which equivalence in peak impact force as achieve. CONCLUSIONS: Four training sessions was sufficient for naïve participants to exhibit fall impact characteristics similar to experts in an anecdotally-effective landing strategy, and support further study. To our knowledge, this was the first study to investigate training for a landing strategy involving stepping after losses of balance from standing.
The utility of a safety climate scale among workers with a work-related permanent impairment who have returned to work
Authors: Huang Yueng-Hsiang , Sears Jeanne M. , He Yimin , Courtney Theodore K. , Rega Elisa , Kelly Anna
Published: August 2022

BACKGROUND: Safety climate (SC) is a robust leading indicator of occupational safety outcomes. There is, however, limited research on SC among workers who have returned to work with a work-related permanent impairment. OBJECTIVE: This study examined three propositions: (1) a two-level model of SC (group-level and organization-level SC) will provide the best fit to the data; (2) antecedent factors such as safety training, job demands, supervisor support, coworker support, and decision latitude will predict SC; and (3) previously reported associations between SC and outcomes such as reinjury, work-family conflict, job performance, and job security will be observed. METHOD: A representative cross-sectional survey gathered information about experiences during the first year of work reintegration. About one year after claim closure, 599 interviews with workers were conducted (53.8% response rate). Confirmatory factor analyses were conducted to test the factor structure of the SC construct. Further, researchers used correlation analyses to examine the criterion-related validity. RESULTS: Consistent with general worker populations, our findings suggest the following: (1) the two-factor structure of SC outperformed the single-factor structure in our population of workers with a permanent impairment; (2) correlations demonstrate that workplace safety training, decision latitude, supervisor support, coworker support, and job demands could predict SC; and (3) SC may positively impact reinjury risk, work-family conflict, and may increase job performance and job security. CONCLUSIONS: Our study validated a two-factor SC scale among workers with a history of disabling workplace injury or permanent impairment who have returned to work. Practical applications of this scale will equip organizations with the necessary data to improve working conditions for this population.
Health and fitness data for police officers within a health and wellness program: Implications for occupational performance and career longevity
Authors: Lockie Robert G. , Dawes J. Jay , Orr Robin M.
Published: August 2022

BACKGROUND: Health and wellness programs can be implemented at police departments. Little research has detailed the characteristics of officers within these programs. OBJECTIVE: To analyse the health and fitness data of officers involved in a health and wellness program from 2018–2020, and to profile the officers involved relative to population norms. METHODS: Analysis was conducted on archival data from 633 officers (523 males, 110 females) who participated in a health and wellness program from a large city police department. Data included: body mass; body fat percentage; blood pressure (BP); estimated maximal aerobic capacity; sit-and-reach; push-ups; vertical jump; grip strength; sit-ups; bench press ratio. Data were grouped by year (2018, 2019, 2020), and a univariate ANCOVA with Bonferroni post hoc adjustment determined any significant between-group differences. Individual officer data were also compared to population norms. RESULTS: The 2020 group had higher systolic BP compared to both other groups, and superior sit-and-reach and grip strength compared to the 2018 group (p < 0.05). Compared to population norms across the 3 years, 74–86% of officers had BP elevated above normal levels. Depending on the fitness component measured most officers (69–98%) were categorised as average or better. CONCLUSIONS: There were few differences between the year groups, although the 2020 officers did have superior sit-and-reach and grip strength. The higher systolic BP from the 2020 group may be indicative of the challenges of the year (pandemic, civil unrest). Officers generally had good profiles relative to population norms. The wellness program appeared to benefit the well-being of officers.
Lung tumor segmentation using dual-coupling net with shape prior based on lung and mediastinal window images from chest CT images
Authors: Byun Sohyun , Jung Julip , Hong Helen , Kim Bong-Seog
Published: August 2022

BACKGROUND: Volumetric lung tumor segmentation is difficult due to the diversity of the sizes, locations and shapes of lung tumors, as well as the similarity in the intensity with surrounding tissue structures. OBJECTIVE: We propose a dual-coupling net for accurate lung tumor segmentation in chest CT images regardless of sizes, locations and shapes of lung tumors. METHODS To extract shape information from lung tumors and use it as shape prior, three-planar images including axial, coronal, and sagittal planes are trained on 2D-Nets. Two types of window images, lung and mediastinal window images, are trained on 2D-Nets to distinguish lung tumors from the thoracic region and to better separate the boundaries of lung tumors from adjacent tissue structures. To prevent false-positive outliers to adjacent structures and to consider the spatial information of lung tumors, pairs of tumor volume-of-interest (VOI) and tumor shape prior are trained on 3D-Net. RESULTS In the first experiment, the dual-coupling net had the highest Dice Similarity Coefficient (DSC) of 75.7%, considering the shape prior as well as mediastinal window images to prevent the leakage of adjacent structures while maintaining the shape of the lung tumor, with 18.23% p, 3.7% p, 1.1% p, and 1.77% p higher DSCs than in the 2D-Net, 2.5D-Net, 3D-Net, and single-coupling net results, respectively. In the second experiment with annotations for two clinicians, the dual-coupling net showed outcomes of 67.73% and 65.07% regarding the DSC for each annotation. In the third experiment, the dual-coupling net showed 70.97% for the DSC. CONCLUSIONS The dual-coupling net enables accurate segmentation by distinguishing lung tumors from surrounding tissue structures and thus yields the highest DSC value.

Heavy metal pollution in soil has received more attention in recent years because of an increase in human activities and its potential effects on ecology and human health. This study assessed the occurrence of heavy metals (As, Pb, Cu, Zn, and Cd) in different cultivated land and their ecological risk in Dong Thap Province, Vietnam. Seventeen samples collected in paddy, vegetable, perennials, and ornamental soils were measured for heavy metal concentrations and soil structure. The data were analyzed using Pearson correlation, principal component analysis (PCA), cluster analysis (CA), Nemerow pollution index (PIN), geoaccumulation index (Igeo), pollution load index (PLI), and potential ecological risk index (RI). The results revealed that the soil structure was clay loam and silt clay loam. Heavy metal concentrations were within the national limits with the order of Zn>Cu>Pb>As>Cd. Pearson correlation and PCA indicated that heavy metals were strongly correlated, and agriculture and soil formation were responsible for their presence in soil. The sampling sites were divided into four groups using CA, in which paddy and crop soils had the highest content of heavy metals. Based on PIN values (0.82-2.92), the heavy metal pollution ranged from warning to moderate level. As had the highest accumulation potential in the soil, with the Igeo values ranging from 0.12-2.05. The risk of heavy metal pollution in agricultural soil to ecology was low to moderate. Despite that, it is recommended to annually monitor the occurrence of heavy metals in agricultural soils to have proper solutions to protect public health.

Introduction: Domestic violence is one of the social issues as old as a society and, due to its extensive scope of impact, it has always drawn the attention of therapists in terms of treatment and pathology. Aim: This study aimed to investigate the effectiveness of the revised protocol of trauma-focused cognitive-behavioral therapy on psychological distress and the quality of life among female victims of domestic violence. Method: The present study was quasi-experimental with a pretest-posttest design and a control group. The statistical population consisted of female victims of domestic violence, who were referred to the court, health centers, homeless shelters, and counseling centers in Karaj, Alborz province in 2020, of which 40 people were selected using the convenience sampling method and randomly divided into two experimental and control groups. The data collection tools included the Psychological Distress and Quality of Life questionnaire. The subjects in the experimental group received the trauma-focused cognitive-behavioral protocol in eight 90-minute sessions. The data were analyzed using multivariate analysis of covariance and SPSS-20. Results: The findings indicated that the trauma-focused cognitive-behavioral therapy caused significant differences between the two groups in psychological distress (F=64.87) at the significance level of 0.001, quality of life - mental health (F=121.19) at the level of 0.001, and quality of life - physical health (F=108.27) at the significance level of 0.001. Conclusion: Based on the research results, it can be concluded that the revised protocol of trauma-focused cognitive-behavioral therapy can reduce psychological distress, and increase the quality of life in female victims of domestic violence. It, as a preventive program, can also be applied in support, health, and treatment centers and increase the efficiency of female victims of domestic violence.

Iza projekta pod nazivom Zelene ulice našeg grada, pokrenutog u Prirodoslovno – grafičkoj školi u Zadru, krije se fotoherbarij. U fotoherbariju se, umjesto sušenih biljnih primjeraka, sakupljaju fotografije biljaka. Osnovna ideja je da učenici fotografiraju biljke po ulicama, parkovima i vrtovima rodnog grada pomoću fotoaparata ili smartphonea. Nakon toga određuje se rod i vrsta biljke, a onda se fotografije biljaka s pripadajućim podacima postavljaju u fotogaleriju po datumu fotografiranja. Svakoj se biljci pridružuje lokacija, tako da se na karti Zadra postavlja točkica na mjestu gdje je biljka fotografirana. Postavljanje fotografija na zemljopisnu kartu u sklopu web stranice škole, pretvara fotografije biljaka u značajnu bazu podataka koja je putem interneta dostupna svima. Izrada fotoherbarija u nastavi biologije izlazi iz okvira tradicionalne nastave, a njegova je vrijednost u poticanju učenika da kroz fotografiranje upoznaju svijet oko sebe, u ovom slučaju biljni svijet, jer su upravo biljke u najmanjem fokusu učeničke pažnje. Osim toga, pri izradi fotoherbarija integrira se nastava biologije s nastavom grafičke grupe predmeta.
Primjena igre uloga u nastavnoj temi „Životinje kontinentalne listopadne šume“
Authors: Rotim Katarina
Published: August 2022

Životinje su tema koja je učenicima uvijek aktualna i zanimljiva. U šestom razredu obrađuju se životinje šume koja je rasprostranjena u području u kojem učenici žive, te samim time imaju određena iskustva. U ovom primjeru za nastavu je osmišljena "TV emisija" u kojoj su sudjelovali svi učenici s određenom ulogom. Učenici su prije same "emisije" istraživali teren na kojem su pronašli životinjske organizme određenog sloja kontinentalne listopadne šume, zatim su u "emisiji" izvještavali o pronađenim životinjama i njihovim prilagodbama na okoliš. Učenici su vrlo entuzijastično pristupili ovakvom načinu rada te su iskazali velik interes za temu. Ujedno su primijenili i vlastita iskustva te na taj način doprinijeli kvalitetnijoj obradi nastavne jedinice.
Održivo odijevanje – doprinos nastavi održivog razvoja
Authors: Blažić Grubelić Melba
Published: August 2022

Posljednjih nekoliko desetljeća održivi razvoj postao je globalno prepoznatljiv termin te je tako ušao i u naše školske kurikule. Ovaj je nastavni sadržaj osmišljen kao radionica koja razvija učeničku kreativnost, nakon čega slijedi istraživački rad. Samim time ima trajnije djelovanje na svijest učenika, a posredno i na njihove obitelji. Česte su nastavne jedinice u kojima se obrađuje utjecaj načina prehrane, gospodarenja otpadom, šumama, vodama i drugih resursa na održivost našega planeta. Unatoč velikoj raznolikosti tema, u mojoj dugogodišnjoj praksi nastavnika biologije i ekologije u srednjoj školi nisam naišla na temu održivog odijevanja, koje u svakodnevnom životu tinejdžera i adolescenata, pogotovo onih ženskoga roda, imaju poprilično značenje. Ova radionica koja u sebi uključuje kreativni pristup odijevanju istoga odjevnog predmeta u učenicima potiče takvo ponašanje i u svakodnevnom životu. Po dovršenoj radionici učenici se usmjeravaju na istraživačku nastavu, koja uključuje upoznavanje sa pojmovima vezanim uz filozofiju življenja poznatu pod nazivom “nula otpada” (zero waste), ali i na osvješćivanje: uvjeta proizvodnje odjevnih predmeta (fair trade); materijale koji se koriste u današnjoj modnoj industriji, kako u visokoj modi, tako i u proizvodnji konfekcijske odjeće te na kraju i na certifikate vezane uz modnu industriju. Moje višegodišnje iskustvo provođenja ovog nastavnog sadržaja i njegovo kontinuirano unaprjeđivanje, kod učenika koji sudjeluju u ovoj aktivnosti uzrokuje promjene ponašanja kao što su: rjeđe kupovanje odjeće, nošenje odjeće na više različitih načina i provjeravanje sastava i eko certifikata pri kupovini odjeće.
Korištenje videolekcija u poučavanju i učenju biologije

Published: August 2022

Epidemiološka situacija vezana uz pandemiju COVID-19, kako u cijelom svijetu, tako i u Hrvatskoj, uvjetovala je određene promjene u organizaciji i provedbi nastavnog procesa. Osim klasične nastave u školi, učenici odgojno-obrazovne ishode ostvaruju i kroz mješoviti oblik nastave koji osim nastave u školi uključuje i nastavu na daljinu ili modelom koji podrazumijeva isključivo rad na daljinu. Zbog promjena u provedbi nastavnog procesa se u organizaciji Ministarstva znanosti i obrazovanja i Agencije za odgoj i obrazovanje pristupilo izradi videolekcija, u sklopu podrške učiteljima i nastavnicima, ali i učenicima i njihovim roditeljima, pri izvođenju nastave na daljinu u školskoj godini 2020./2021. Kako su videolekcije na određeni način novitet i učiteljima i učenicima, cilj je bio analizirati uspješnost ostvarivanja odgojno-obrazovnih ishoda uz rad s učenicima putem videolekcija. Utvrđeno je da učenici uglavnom mogu uspješno ostvariti odgojno-obrazovne ishode propisane Okvirnim godišnjim izvedbenim kurikulumom, uz aktivno uključivanje u nastavni proces, ali i da imaju poteškoće u izdvajanju pojmova ključnih za izgradnju temeljnih koncepata i prikazivanju njihovih međuodnosa. S obzirom na reakcije učenika uz određene aktivnosti, zaključeno je kako bi uspješnijem ostvarivanju odgojno-obrazovnih ishoda svakako doprinijela i provedba praktičnih radova ili priprema video materijala njihove provedbe, ako ih učenici ne mogu samostalno izvesti kod kuće.
Mogućnosti muzeja kao učionice u nastavi biologije
Authors: Barbarić - Gaćina Jelena
Published: August 2022

Nastava u muzeju zahtjeva osmišljavanje i pripremu kako bi se svi učenici potaknuli na uključivanje i usvajanje zadanih ishoda nastave. U ovom radu istražena su tri različita pristupa nastave u muzeju. Prvi pristup uključivao je obilazak muzeja uz vodstvo kustosa muzeja (vođeni pristup), a drugi samostalni obilazak izložbe, u pratnji nastavnika, uz rješavanje prethodno pripremljenih nastavnih listića (samostalni pristup). Treći pristup, koji je nastao kao posljedica pandemijske situacije i nemogućnosti fizičkog obilaska muzeja, uključivao je virtualni obilazak muzeja uz rješavanje nastavnih listića (virtualni pristup). U sva tri pristupa ispitana je uspješnost učenja i zadovoljstvo učenika nastavom u muzeju. Rezultati znanja učenika vođenog i samostalnog pristupa pokazuju razlike i mogućnost korištenja obilaska muzeja uz nastavne listiće kao aktivne nastave. Usporedbom znanja učenika koji su posjetili i onih koji nisu posjetili virtualnu izložbu (virtualni pristup) upućuje na mogućnost korištenja virtualnih izložbi za bolje razumijevanje uzročno – posljedičnih veza. Što se zadovoljstva tiče, uočljivo je puno veće zadovoljstvo učenika nastavom u muzeju i takvim načinom rada u odnosu na nastavu u razredu, ali ne i učenika koji su „posjetili“ virtualni muzej.
Primjer obrade nastavne teme Dišni sustav u strogim epidemiološkim uvjetima
Authors: Barbarić - Gaćina Jelena
Published: August 2022

Pandemija koronavirusa postavila je nove izazove u načinu organizacije i izvođenja nastave. Osim promjena u trajanju školskog sata i broju učenika koji istovremeno smiju pohađati nastavu, zbog epidemioloških preporuka rad u grupama i parovima se ne prakticira. Time je pandemija koronavirusa uvjetovala frontalnu nastavu, koja se inače izbjegava proteklih dvadesetak godina zbog mišljenja da je za učenike takav način nastave pasivan i dosadan, te slabo potiče usvajanje znanja i razumijevanje sadržaja. Da bi se zadovoljili epidemiološki kriteriji bez kompromitiranja kvalitete nastave, u ovom radu je predložena obrada nastavne jedinice Dišni sustav i bolesti dišnog sustava, u kojoj učenici aktivno sudjeluju i bez primjene grupnog rada. Aktivnost učenika postignuta je stalnim komuniciranjem s učenicima i izmjenjivanjem samostalnog rada učenika na rješavanju zadataka i problemskih pitanja te razgovora s učenicima. Osim toga, koristio se i pristup obrnute učionice. Velika prednost u postizanju maksimalne uključenosti učenika u rad, je i manji broj učenika u učionici (polovica razreda). U nastavi je korištena informacijsko – komunikacijska tehnologija, model pluća, radni listići i izvorna stvarnost. Ovim radom pokazano je da se aktivno učenje može postići i pod strogim epidemiološkim uvjetima. Dok su u ovom radu obrađene nastavne jedinice Dišni sustav i bolesti dišnog sustava, isti principi nastave mogu se primijeniti na bilo koju nastavnu jedinicu ili temu.
