effect of uncertainty in a fuzzy Input-Output analysis of water consumption applied to Macedonia
Authors: HRISTOV Jordan , SURRY Yves
Published: December 2023

This paper reconsiders the reliability of the results obtained by Hristov et al. (2012) from the input-output analysis of water consumption, by taking into account the effect of uncertainty inherent in the data. The imprecision and uncertainty is studied within a workable fuzzy environment as introduced by Beynon et al. (2005), where rank reversal is plausible. In addition, the water-intensive structure of the Macedonian economy is investigated by applying Dietzenbacher eigenvector methodology (1992). As suggested in the analysis of Hristov et al. (2012), the water-intensive structure of the economy in Macedonia is confirmed as being mainly focused on agriculture and several industrial sectors, given that rank reversal is absent. Consequently, there is a need to introduce changes in the agricultural production technology as well as the specialization of production in this region.
Prvotne, izgubljene, pretopljene pasme konj v Sloveniji

Published: December 2023

O reji konj na Kranjskem je pisal že Valvasor (1689). Na več mestih v knjigi »Slava vojvodine Kranjske« piše tudi o kraškem konju. Druge pasme, ki so opisane v objavah do leta 1945, so noriški konj, lipicanskec, belgijski konj, ljutomerski kasač, medžimurski konj in drugi konji. Po odredbi kmetijskega ministrstva je bila nekdanja Dravska banovina, leta 1934 razdeljena v področje hladnokrvnih konj s tremi okoliši (medžimurski konj, srednje težki noriški konj, lahki noriški konj) in v dva pasemska okoliša toplokrvnih konj (amerikanski dirkač, lipicanec). Kraški konj je omenjen že v arhivski listini iz leta 1582. To so bili močni konji znani tudi po svoji dolgoživosti. Kraški konj je stara slovenska pasma, ki je od 16. stoletja dalje neposredno sodelovala pri nastanku lipicanca, pasma sama pa je izumrla. Bohinjski konj je bil visok, širok in močan. Pasmo prvi omenja dr. Bleiweis (1855). Nastal naj bi na začetku 18. stol. z oplemenjevanjem domačih kobil z žrebci pasme nonius (ogrskimi žrebci). Prvotni stari bohinjski konj je izginil z uvajanjem težkih noriških žrebcev. Kobariški konj je bila težka vprežna pasma konj, ki so jo redili že od nekdaj v soški dolini in na njenem obrobju. Pasma je bila zelo čislana tudi v Furlaniji. Prva svetovna vojna je povsem premešala pasemsko strukturo in o usodi kobariškega konja po letu 1928 ni podatkov. Posavinjski konj, imenovan tudi savinjski, je bil vzgojen v Savinjski dolini. Nastal je s križanjem noriške in ardenske pasme konj. To je bil srednje težak konj, ki je tudi izumrl.

Published: December 2023

Objectives

Twin pregnancies are at increased risk of preterm birth (PTB) compared to singletons. Evaluation of cervical length (CL) represents the optimal tool to screen PTB in singleton. Conversely, there is less evidence on the use of CL in twins. Our aim was to evaluate the methodological quality and clinical heterogeneity of clinical practice guidelines (CPGs) on the CL application in twins using AGREE II methodology.

Methods

MEDLINE, Scopus, and websites of the main scientific societies were examined. The following aspects were evaluated: diagnostic accuracy of CL, optimal gestational age at assessment and interventions in twin pregnancies with reduced CL. The quality of the published CPGs was carried out using “The Appraisal of Guidelines for REsearch and Evaluation (AGREE II)” tool. The quality of guideline was rated using a scoring system. Each considered item was evaluated by the reviewers on a seven-point scale that ranges from 1 (strongly disagree) to 7 (strongly agree). A cut-off >60 % identifies a CPGs as recommended.

Results

The AGREE II standardized domain scores for the first overall assessment had a mean of 74 %. The score was more than 60 % in the 66.6 % of CPGs analyzed indicating an agreement between the reviewers on recommending the use of these CPGs. A significant heterogeneity was found; there was no specific recommendation on CL assessment in about half of the published CPGs. There was also significant heterogeneity on the CL cut-off to prompt intervention.

Conclusions

Despite the fact that the AGREE II analysis showed that the majority of the included guidelines are of good quality, there was a significant heterogeneity among CPGs as regard as the indication, timing, and cut-off of CL in twins as well as in the indication of interventions.

The Alpha Power Muth-G Distributions and Its Applications in Survival and Reliability Analyses
Authors: Eghwerido Joseph Thomas , Agu Ikechukwu Friday
Published: December 2023

The generalization of the family of distributions that could provide a simple, and efficient algorithm for parameter estimation and study of the behavior of datasets from various fields has received significant interest. Such a model has enormous advantages, such as its flexible nature, and the regression form can easily be derived. In the literature, various generalized families of distributions have been introduced. Despite the merits of these distributions, they still have some limitations due to many parameters in the model. Thus, the estimation of parameters often becomes cumbersome. Therefore, this study introduced the alpha power Muth or Teissier-G family of continuous distributions with well-defined parameters, and obtained the joint progressive type-II censoring scheme and their reliability measures. Furthermore, we obtained the global and local influences of the APTG model. We used real-life and simulated data to evaluate the numerical applications of the introduced model. The results show that the alpha power Muth or Teissier-G family of distributions gave the best fits to both datasets than some existing models.

Published: December 2023

The article examines the role of social partners (trade unions and employers) in the field of occupational safety and health (OSH). The Covid-19 pandemic directed attention to the importance of greater national and European level policy coordination to protect and promote healthy, safe, and well-adapted work environments. On the basis of two sectors, hospitals and social services with a focus on elder care, the article asks how OSH policy interventions at the national level and the European level are interlinked. To explore interlinkages, the article focuses on OSH policy coordination between national social partners and European level sectoral social dialogue. The analysis is informed by actor-centred institutionalist and multilevel governance approaches and uses qualitative data. The article explores patterns of interlinkages between the national and European levels in two sectors and six countries and discusses the limitations of applying a cross-national and multilevel conceptual approach. The analysis shows that the pandemic has promoted some coordination at national and between national and EU levels, yet still rather modest interlinkages and degrees of ‘vertical’ coordination can be observed. The paper concludes that there continues to be a degree of ‘in-the-making’ to the multilevel governance of employment relations, even in the presence of common challenges.
De la proximité à la tyrannie : dynamiques relationnelles et pratiques de gestion des femmes cadres

Published: December 2023

Depuis les dernières années, la question du leadership des cadres retient l’attention des chercheurs et des professionnels (Alvesson et al., 2017; Leroux et al., 2019; Wainsztok, 2017). L’objectif de cet article est de comprendre les dynamiques relationnelles et les pratiques de gestion des femmes cadres. Cette recherche s’appuie sur une théorie du travail humain afin de saisir les dynamiques relationnelles et les rapports sociaux vécus dans le travail. La méthodologie repose sur un devis de recherche qualitatif à partir de 51 entrevues individuelles avec des femmes cadres. Les résultats révèlent quatre grandes catégories de pratiques de gestion : 1) des relations de proximité avec les équipes et le partage du travail réel; 2) des relations fusionnelles marquées par la sollicitude zélée et le care dévalorisé; 3) la mise à distance des équipes et du travail réel; 4) des rapports de contrôle et de surveillance, et la dictature/tyrannie. La contribution de cet article consiste à montrer la diversité des pratiques de gestion qui peuvent être mobilisées par des femmes cadres, au-delà des débats qui persistent, à savoir si les pratiques de gestion des femmes sont différentes ou similaires à celles des hommes.
dimensions de l'envie

Published: December 2023

L’être humain fait face au cours de sa vie à une multitude d’émotions, notamment la joie, la peine et la colère, qui sont ouvertement reconnues comme universelles, mais qu’en est-il de l’envie? Bien que l’envie soit présente dans toutes les cultures depuis le début de l’humanité, elle est stigmatisée, considérée comme moralement indésirable et souvent associée à des comportements socialement inacceptables. L'étude de l'envie en psychologie est encore un domaine relativement jeune avec peu d'études empiriques. Des instruments de mesure ont été construits afin de mesurer cette émotion; cependant, les auteurs ne s’entendent pas sur la structure complexe de l’envie. L’objectif de cet article est de parcourir les différentes conceptions de l’envie étayées dans la littérature et de proposer un cadre conceptuel pour d’éventuelles recherches sur le construit latent de l’envie, notamment en milieu de travail.
Equity and local health systems: a qualitative evaluation of the experiences of local health service leads during the first two years of the NHS Low Calorie Diet programme pilot

Published: December 2023

Background: Obesity and type 2 diabetes (T2DM) can both profoundly impact health and wellbeing. Their prevalence largely follows a social gradient. The National Health Service Low Calorie Diet programme in England aims to support people to achieve T2DM remission while also reducing health inequalities. We aimed to explore the experiences of local health service leads and identify barriers and facilitators in relation to the equitable mobilisation of the Low Calorie Diet programme.
Methods: Twenty semi-structured interviews were completed with 24 locality leads across the first two years of the Low Calorie Diet programme. Interviewees were purposively sampled from the 10 localities who undertook the Low Calorie Diet programme pilot. Each interview explored a number of topics of interest, including referrals, training, communication, incentivisation, governance and engagement, before being subjected to a thematic analysis.
Results: From the data, seven core themes were identified: COVID-19 and primary care capacity and engagement; methods of communication; approaches to training; approaches to incentivisation; approaches to referrals; barriers to referrals; and the importance of collaboration. COVID-19 presented a specific challenge to the mobilisation and delivery of the Low Calorie Diet programme; however, our findings demonstrate the large variation and differences in the approaches taken when delivering the programme across 10 geographically and demographically distinct pilot sites. We also identified a lack of a recognised approach or strategy to mobilisation and delivery support for the Low Calorie Diet programme, such as proportionate universalism, which is a social policy response to tackling health inequalities by ensuring that service delivery is equitable.
Conclusions: Health inequalities remain a significant challenge, and health service leads have the potential to adopt an equity perspective from the start of programme mobilisation. In doing so, resources at their disposal can be managed equitably and can therefore contribute to efforts to reduce the potential occurrence of intervention-generated inequalities.

Published: December 2023

Background: Previous randomised controlled trials have observed individual differences in response to Glucagon-Like Peptide-1 Receptor Agonists (GLP1RA) according to baseline characteristics such as glycated haemoglobin (HbA1c) and weight. The Association of British Clinical Diabetologists (ABCD) launched a nationwide UK audit in January 2019 to assess the clinical utility, efficacy and safety of injectable semaglutide in routine practice. The aim of this analysis was to investigate associations between baseline characteristics and HbA1c and weight reductions with semaglutide in real-world use.
Methods: Data were extracted from the secure online tool and individuals who had baseline and follow-up data available within a defined 6 (3-9) month window were included. Variables were assessed as both continuous variables and categorical variables in a multivariate regression model. Missing data were multiply imputed.
Results: In total, 620 individuals were included. Baseline characteristics: (mean±SD) age was 58.7±10.7 years, HbA1c 81.6±18.5 mmol/mol (9.5±1.7%), weight 108.2±24.2 kg and body mass index (BMI) 37.6±7.6 kg/m2. Median diabetes duration was 11.2 years (IQR 6.6-16) and 50.5% (313/620) of subjects were male. The median follow-up time was 0.5 years. HbA1c reduced by 14.9 mmol/mol (95% CI 13.5, 16.1) [-1.4% (95% CI - 1.2, -1.5)]; p<0.001; and weight reduced by 4.2kg (95% CI 3.6, 4.8; p<0.001). Higher HbA1c, younger age and GLP1RA naïvety were associated with larger HbA1c reduction. Higher baseline weight/BMI and GP1RA naïvety were associated with larger weight reduction.
Conclusion: In this real-world study, baseline HbA1c and weightwere important predictors of HbA1c and weight reduction outcomes following initiation of semaglutide in routine clinical practice. Our data mirror existing randomised controlled trial data, but further evidence is being collected over a longer follow-up period.

Published: December 2023

The aim of this study was to develop a prognostic model for radioactive iodine (RAI) therapy outcome in patients with Graves‘ disease. We enrolled 127 patients. Information on RAI therapy, ultrasound indexes of thyroid, and other lifestyle factors was collected. The competing risk model was used to estimate the multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for nonhealing or recurrence of hyperthyroidism (NHRH). The performance of the model was assessed by receiver operator characteristic analysis and the Brier score and internally validated by bootstrap resampling. Then, a nomogram was developed. Forty-one cases (32.2%) of NHRH were documented. Positive Ki-67 expression, a higher dose of per-unit thyroid volume, and females showed lower risks of NHRH (all P < 0.05). The HR values (95% CI) were 0.42 (0.23, 0.79), 0.01 (0.00, 0.02), and 0.47 (0.25, 0.89), respectively. The bootstrap validation showed that the model had the highest accuracy and good calibration for predicting cumulative risk of NHRH at 180 days after RAI therapy (AUC = 0.772; 95% CI: 0.640–0.889, Brier score = 0.153). By decision curve analysis, the nomogram was shown to have a satisfactory net benefit between thresholds of 0.20 and 0.40. Ki-67, ultrasound volumetry, and scintigraphy techniques can play important roles in evaluating RAI therapy outcome in Graves‘ disease patients. The prediction nomogram shows reasonable accuracy in predicting NHRH.

Published: December 2023

Background: The simple explanation of burnout syndrome is exhaustion from work and work-related factors. It is more common in work that requires face-to-face contact with people, such as dentists. In this study, we researched the burnout levels of dentists working in Turkey and evaluated them according to gender, title, place of work and experience.
Methods: Burnout scores were determined by the Copenhagen Burnout Inventory. This questionnaire was delivered to dentists online through various social media applications. We analyzed data via SigmaPlot Software.
Results: The answers of a total of 477 dentists were considered valid. We observed that 73,5% of them had high burnout scores. A statistically significant difference was found in the evaluations according to the title and workplace. Experience and gender do not statistically affect burnout scores.
Conclusion: It has been observed that dentists working in Turkey are more likely to face burnout syndrome at high levels. It has been predicted that patient burden may be closely related to burnout syndrome.
The Effect of the Toothbrushing and Surface Treatments on the Surface Roughness of Interim Crown Materials Used for Conventional, Subtractive, and Additive Manufacturing Techniques: An in Vitro Study
Authors: BOZOĞULLARI Hatice Nalan , KÖROĞLU Ayşegül , ŞAHİN Onur , İZZETAĞA Beşar
Published: December 2023

Background: This study aimed to compare the effect of the surface treatment and toothbrushing abrasion on the surface roughness of interim crown material specimens manufactured using conventional, subtractive, and additive processing techniques.

Material and methods: 80 disk-shaped specimens were prepared from 4 different interim crown materials; one auto-polymerized polymethyl methacrylate resin (PMMA);(IM) and one bis-acryl composite resin;(AC) for conventional technique, one computer-aided design/computer-aided manufacturing (CAD-CAM) PMMA block;(TC) for subtractive process, one 3-dimensionally (3D) printed resin;(CB) for additive process. Specimens of each interim crown material were divided into two subgroups according to applied surface treatments; conventional polishing or surface sealant agent coupling (n=10). The surface roughness values of specimens before (Ra0) and after 10,000 cycles of toothbrushing (Ra1) were measured with a profilometer. Data were statistically analyzed.

Results: The polished groups of all interim crown materials showed significantly higher Ra0 values compared to the sealant groups before toothbrushing (p˂0.05). While the polished IM groups exhibited the highest Ra0 value (0.44±0.08), the sealed TC groups exhibited the lowest Ra0 value (0.23±0.06). The Ra values of all material groups increased after simulated 1-year toothbrushing. While the polished IM group exhibited the highest Ra1 value (0.45±0.14), the sealed CB group had the lowest Ra1 value (0.31±0.09).

Conclusion: It was observed that toothbrushing caused an increase in the surface roughness of all interim materials. The application of a surface sealant agent to these materials is more effective than polishing to reduce surface roughness. Sealed 3D printed resin for additive process exhibited the lowest mean roughness value after toothbrushing.

The Size of the Household of Šiauliai Parish Residents in the First Half of the 19th Century (According to the Data of the Visitations)
Authors: Giedrimas Laurynas
Published: December 2023

The article aims to reveal the possibilities of the data contained in the parish visitations in determining the average household size of the residents of Šiauliai parish. Firstly, the data on visitations allows us to learn about the number of residents who came to catholic confession and those who did not come to catholic confession. Secondly, the source allows us to learn about the number of households in all parish settlements. The data is important for calculating the number of residents in the settlements and in the whole parish. The data on the number of residents allows us to calculate the size of the households in separate settlements and in the whole parish. Moreover, this data can be used for the reconstruction of parish geographical territory. On the other hand, the data on parish visitations can be incorrect as usually statistical information was rewritten from the earlier sources. Considering Šiauliai catholic parish visitations, it should be noted that later visitations were rewritten from the visitations of the year 1820, thus this research only deals with the situation of the year 1820. The analysis revealed that the geographical territory of Šiauliai parish has not significantly changed since the middle of the 17th century. Also, those settlements that were the largest in terms of population in the middle of the 17th century, remained the largest in the first half of the 19th century. After calculating the ratio of those who went to confession and those who did not go, it was found that in the visitations of Šiauliai parish, only the number of Catholics was given, and in some settlements far from the center of the parish, there was a high number of those who did not go to confessions, most likely it indicates pastoral problems, and not the population of other denominations. On average, 9.7 people lived in one household in Šiauliai parish, 7.98 lived in Šiauliai city, 14.5 lived in Kužiai town, and 11.35 lived in Meškuičiai town. After comparing the results of the research with the data of other cities and towns, it can be said that larger cities were characterized by smaller households, while small towns were characterized by larger households. Meanwhile, it is not easy to compare the obtained research results with the household data of the Central and Eastern European population, because the research results are highly dependent on the concept of the household. Nevertheless, it can be said that the average household size of Šiauliai parish was close to the household size of the residents of Nereta (Latvia).
In the Footsteps of Publishing of Motiejus Valančius’ „Vaikų knygelė“
Authors: Maskuliūnienė Džiuljeta
Published: December 2023

1868 was a fateful year for Lithuanian children’s literature, as two books by Samogitian Bishop Motiejaus Valančius (1801–1875) appeared: "Vaikų knygelė" (Engl. Children’s Book) and "Paaugusių žmonių knygelė" (Engl. Adolescence Book). They mark the beginning of literature for Lithuanian children and teenagers. This is evidenced not only by the symbolic titles of both books, which indicate the addressee – children and teenagers, young people. It is important that Valančius thinks about a specific reader – a child, so in the Foreword of the "Vaikų knygelė" he hopes that “children will not regret while reading” his book, that is, they will not get bored. The author thinks that children while reading Aukso altorius (Engl. Golden Altar) only find prayers and litanies, however, they want to learn about interesting things to tell others, and if they do not find such things, “sometimes they can’t even learn”. Therefore, it is necessary to read special books for children in the post-elementary period. It was a modern approach in those times, which is not outdated even today.
The article aims to discuss the publishing path of Valančius’ "Vaikų knygelė" as well as the most important modifications (textual and visual) this collection of didactic short stories underwent. The article analyses the following aspects: 1) issues of selection of texts and their presentation; 2) preservation of the dimension of authenticity of texts; 3) what was the presentation of the texts of Valančius’ "Vaikų knygelė" written in dialect over time.
It is very important to emphasize that the linguistic expression of Valančius’ works, especially the stylistic layer, is an interesting phenomenon in all Lithuanian literature. Paradoxically, when the reissues were published, the stylistic layer of the works was often affected, the dialect was levelled, so a considerable part of the authentic layer, the exotic whiff of didactic prose of the 19th century, was “erased”. The interdisciplinary research approach is employed in the present research, the perspectives of literary studies, textology and art studies are combined: it is based on the scientific insights of the literary expert and textologist Paulius Subačius, the analysis of the illustrations of various editions of Valančiaus’ "Vaikų knygelė" by the art critic Ingrida Korsakaitė, the considerations of the literary researcher Vanda Zaborskaitė on the aesthetic value of the archaic nature of Valančius’ text, etc.
Semiotics of the Sensible: From Sensation to Intuition
Authors: Fontanille Jacques
Published: December 2023

Classifying semiotic systems by the sensory channels employed to communicate them is simple, but specious: we thus fail to inquire into that which is actually semiotic about different types of sensory experience. In order to explicate their distinctive semiotic properties, these sensory types – touch, hearing, vision, olfaction, sensomotorics – need to be interrogated as phenomena. This way, each of the semiotic sensible modes shall be characterized by a specific field of presence. Schematic forms of the sensible thus obtained will give rise to a typology of sensible “bodies” – the envelope-body, the cavity-body, the point-body, the flesh-body – as well as to a typology of their “dynamics” (deformation, intimate movements etc.) and, finally, to a typology of semiotic “imprints” which these dynamics give rise to. Next, we should interrogate the possibilities of employing such typologies in concrete analyses.

Our primary presupposition is that, in most cases, objects of analysis – text, painting, film, choreography etc. – are multisensory, and thus the task of their explanation involves an articulation of several sensible modes. This kind of articulation is decisive for interpretation. The case of artworks is very suggestive in this sense: for example, in a painting, the same “visual” substances of expression can give rise to both a figurative and iconic presentation, grounded in the typical field of visuality, and to a plastic dimension which brings forth other types of field – somatic, affective, symbolic, or mythical.

This means that the articulation of sensible modes is the object of a second-order schematization – the schematization of a trans-sensible dimension, wherein intuition produces schematic forms that become expressions for contents not directly determined by sensory modes. The trans-sensible dimension activates syntheses of sensible modes; as we have learned from Kant, these syntheses are not of the conceptual order: they are activated in intuition, make use of the imagination, and are always contained in the sensible order which is both sensory and emotional.

For the first time, geochronological studies of zircon and monazite quartz syenites of the Nizyanka massif in the northern part of the Lozovatka anticline of the West Azov region (Lypovenki area) were performed. They break through the metamorphic rocks of the Kayinkulak and Upper Tokmak strata of the West Azov series and the later intrusions of diabases. «Relic cores» and later thin shells are observed in zircon from quartz syenites. Considering that quartz syenite did not undergo imposed endogenous processes, it was the shells in zircon crystals that crystallized during their formation. The U-Pb age of the relict zircon is 2858±51 Ma. Monazite is synpetrogenic for quartz syenites and was probably formed simultaneously with thin shells of zircon. The U-Pb age of monazite is 2065.5±7.2 Ma. According to the obtained data, quartz syenites were melted from Archean rocks in a crustal magmatic source in the Paleoproterozoic at the stage of the general collision of the Archean crust of the Ukrainian Shield and the Volga-Ural continents.

AbstrakObesitas disebabkan adanya kelebihan kalori dalam tubuh. Penurunan obesitas dapat dilakukan dengan cara menghambat penyerapan lemak sebagai sumber utama kelebihan kalori. Salah satu cara yang dapat dilakukan untuk menghambat penyerapan lemak adalah dengan menghambat aktivitas lipase pankreas. Penelitian ini dilakukan untuk menentukan aktivitas inhibitor lipase ekstrak metanol daun mangga arum manis (Mangifera indica L. cv Arum manis) dan kweni (Mangifera odorata Griff.). Tahapan penelitian diawali dengan ekstraksi menggunakan metode maserasi lalu diikuti dengan uji kadar total fenol, kadar flavonoid, dan uji aktivitas inhibitor lipase ekstrak daun mangga arum manis serta kweni. Hasil uji kadar total fenol menunjukkan total fenol pada ekstrak daun mangga arum manis dan kweni berturut-turut yaitu 246,94 mg GAE/g dan 176,11 mg GAE/g. Kadar flavonoid daun mangga arum manis, yaitu 129,95 mg.QE/g, sedangkan daun mangga kweni yaitu 26,50 mg.QE/g. Masing-masing ekstrak diuji kemampuannya dalam menghambat lipase pankreas secara in vitro. Nilai IC50 ekstrak daun mangga arum manis dan kweni, yaitu 61,55 µg/mL dan 79,98 µg/mL. Nilai tersebut lebih tinggi dibandingkan kontrol positif, yaitu orlistat (18,01 µg/mL). Dengan demikian, ekstrak daun mangga arum manis dan kweni dapat menghambat aktivitas lipase pankreas dan berpotensi untuk dikembangkan sebagai antiobesitas.AbstractObesity is caused by excess calories in the body. Reducing obesity can be done by inhibiting the absorption of fat as the main source of excess calories. One way that can be done to inhibit fat absorption is by inhibiting pancreatic lipase activity. This research was conducted to determine the lipase inhibitor activity of methanol extract of arumanis (Mangifera indica L. cv Arumanis) and kweni (Mangifera odorata Griff.) mango leaves. The research stages began with extraction using the maceration method, followed by testing the total phenol content, flavonoid content, and testing the lipase inhibitor activity of arumanis and kweni mango leaf extracts. The results of the total phenol content test showed that the total phenol in Arumanis and Kweni mango leaf extracts was 246.94 mg GAE/g and 176.11 mg GAE/g, respectively. The flavonoid content of Arumanis mango leaves is 129.95 mg.QE/g, while that of Kweni mango leaves is 26.50 mg.QE/g. Each extract was tested for its ability to inhibit pancreatic lipase in vitro. The IC50 values of Arumanis and Kweni mango leaf extracts are 61.55 µg/mL and 79.98 µg/mL. This value is higher than the positive control, namely orlistat (18.01 µg/mL). Thus, Arumanis and Kweni mango leaf extracts can inhibit pancreatic lipase activity and have the potential to be developed as an anti-obesity agent.

AbstrakGrammatophyllum stapeliiflorum merupakan jenis anggrek epifit dengan pertumbuhan vegetatif dan generatif yang relatif lambat. Anggrek ini termasuk ke dalam kelompok CITES Apendiks II. Kultur in vitro merupakan usaha perbanyakan paling efektif untuk tanaman anggrek. Penggunaan media kultur dan Zat Pengatur Tumbuh (ZPT) yang tepat akan meningkatkan keberhasilan perkecambahan biji anggrek secara in vitro. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi media MS dan penambahan BAP terbaik terhadap perkecambahan anggrek G. stapeliiflorum secara in vitro. Penelitian ini menggunakan rancangan acak lengkap dengan 6 perlakuan dan 4 ulangan. Perlakuan berupa variasi konsentrasi media MS dan BAP, yaitu: MS penuh; MS ½ hara makro; MS ¼ hara makro; MS penuh + 1 ppm BAP; MS ½ hara makro + 1 ppm BAP; dan MS ¼ hara makro + 1 ppm BAP. Parameter yang diamati pada penelitian ini, yaitu waktu muncul protokorm dan persentase tahap perkecambahan biji. Data dianalisis menggunakan uji ANOVA dan uji lanjut Duncan New Multiple Range Test dengan taraf 5%. Hasil penelitian menunjukkan bahwa pemberian BAP mampu mempercepat waktu muncul protokorm. Konsentrasi media MS ¼ hara makro + 1 ppm BAP merupakan konsentrasi terbaik untuk perkecambahan biji anggrek tahap 0 hingga tahap 3, sedangkan konsentrasi media MS ¼ hara makro merupakan konsentrasi terbaik untuk mencapai tahap 4 perkecambahan biji anggrek G. stapeliiflorum secara in vitro.AbstractGrammatophyllum stapeliiflorum is a type of epiphytic orchid with relatively slow vegetative and generative growth. This orchid is included in the CITES Appendix II group. In vitro culture is the most effective propagation method for orchid plants. The use of appropriate culture media and growth regulators will increase the success of orchid seed germination in vitro. This study aims to determine the effect of the best concentration of MS media and the addition of BAP on the germination of G. stapeliiflorum orchids in vitro. This study used a completely randomized design with 6 treatments and 4 replications. The treatments consisted of varying concentrations of MS and BAP media, namely: full MS; MS ½ macro nutrients; MS ¼ macro nutrients; full MS + 1 ppm BAP; MS ½ macro nutrients + 1 ppm BAP; and MS ¼ macro nutrients + 1 ppm BAP. The parameters observed in this study were the time when the protocorm appeared and the percentage of seed germination stages. Data were analyzed using the ANOVA test and the Duncan New Multiple Range Test with a level of 5%. The results of the study showed that administration of BAP was able to speed up the time when protocorm appeared. MS media concentration ¼ macro nutrients + 1 ppm BAP is the best concentration for stage 0 to stage 3 orchid seed germination, while MS media concentration ¼ macro nutrients is the best concentration for achieving stage 4 germination of G. stapeliiflorum orchid seeds in vitro.

AbstrakUdang mantis (Harpiosquilla raphidea) memiliki karakter morfologi yang berbeda dengan jenis udang lainnya. Selain itu H. raphidea dikenal sebagai hewan air yang mempunyai nilai ekonomis tinggi, khususnya di kawasan mangrove Tanjung Jabung Barat Provinsi Jambi. Pemanfaatan H. raphidea secara ekonomis dianggap perlu diselaraskan dengan kajian morfologi, khususnya yang terkait dengan hubungan panjang dan berat untuk mendukung nilai jual. Penelitian ini bertujuan untuk menganalisis morfologi dan pola pertumbuhan H. raphidea. Sampel dikoleksi dari perairan mangrove Pangkal Babu Desa Tungkal 1 Tanjung Jabung Barat. Analisis morfologi menunjukkan bahwa H. raphidea memiliki ciri khas yaitu adanya maksiliped (lengan predator) bercakar tajam dan tidak terdapat perbedaan morfologi antara individu jantan dan betina. H. raphidea yang paling banyak dikoleksi berukuran 168–203mm. Pola pertumbuhan H. raphidea  adalah alometrik negatif yang artinya pertambahan panjang lebih cepat dibandingkan pertambahan beratnya baik untuk individu jantan maupun betina. Sehingga dapat disimpulkan bahwa hubungan panjang dan berat H. raphidea dari Perairan Pangkal Babu Tanjung Jabung Barat menunjukkan pola pertumbuhan yang sejalan dengan H. raphidea dari kawasan perairan lainnya di Indonesia.AbstractMantis shrimp (Harpiosquilla raphidea) has morphological characteristics that are different from other types of shrimp. Apart from that, H. raphidea is known as an aquatic animal that has high economic value, especially in the West Tanjung Jabung mangrove area, Jambi Province. The economic use of H. raphidea is considered to need to be harmonized with morphological studies, especially those related to the relationship between length and weight to support selling value. This study aims to analyze the morphology and growth patterns of H. raphidea. Samples were collected from the mangrove waters of Pangkal Babu, Tungkal 1 Tanjung Jabung Barat Village. Morphological analysis shows that H. raphidea has distinctive characteristics, namely the presence of maxilipeds (predatory arms) with sharp claws and there are no morphological differences between male and female individuals. The most commonly collected H. raphidea measures 168–203mm. The growth pattern of H. raphidea is negative allometric, which means that the increase in length is faster than the increase in weight for both male and female individuals. So it can be concluded that the relationship between length and weight of H. raphidea from the Pangkal Babu waters of West Tanjung Jabung shows a growth pattern that is in line with H. raphidea from other water areas in Indonesia.
