Authors: Nasrudin Nasrudin , Wahyudhi Aditya , Gian Ari
Published: March 2022

Cekaman garam merupakan cekaman abiotik yang mampu menghambat pertumbuhan dan produksi padi melalui mekanisme metabolisme. Usaha yang dapat dilakukan untuk membudidayakan tanaman padi dalam kondisi cekaman garam yaitu mengetahui karakteristik suatu varietas padi agar dapat tumbuh dan berkembang optimal. Tujuan penelitian untuk mengkaji karakteristik pertumbuhan dan hasil dua varietas padi tercekam garam NaCl. Rancangan Acak Lengkap faktorial digunakan dalam penelitian ini. Faktor pertama konsentrasi NaCl yang terdiri atas dua taraf yaitu 0 dS m-1 dan 4 dS m-1. Faktor kedua varietas padi yang terdiri atas dua taraf yaitu varietas Dendang dan varietas IPB 4S. Berdasarkan hasil penelitian menunjukkan bahwa padi varietas Dendang memiliki jumlah anakan (JA), panjang akar (PA), jumlah malai per rumpun (JMpR), persentase gabah isi (GI), dan bobot kering tajuk (BKT) yang lebih besar dibandingkan dengan padi varietas IPB 4S. Namun, padi IPB 4S memiliki karakteristik tanaman yang lebih tinggi dibandingkan padi varietas Dendang. Pemberian konsentrasi NaCl 0 dS m-1 menghasilkan jumlah anakan dan akar lebih panjang dibandingkan pemberian konsentrasi NaCl 4 dS m-1. Hasil analisis korelasi menunjukkan bahwa beberapa parameter berkorelasi positif, yakni panjang akar terhadap jumlah anakan (R= 0,89), bobot kering tajuk terhadap jumlah anakan dan panjang akar (R= 0,89; R= 0,91), dan persentase gabah isi terhadap bobot kering tajuk, panjang akar, jumlah malai per rumpun, dan jumlah anakan (R= 0,87; R= 0,76; R= 0,83; R= 0,89). Penggunaan varietas padi berpengaruh nyata terhadap karakteristik pertumbuhan dan hasil yang terlihat pada parameter JA, PA, JMpR, GI, dan BKT. Sedangkan konsentrasi NaCl berpengaruh nyata terhadap karakter tinggi tanaman.

Published: March 2022

Opioidiriippuvuuden korvaushoidon potilaiden siirtyminen apteekkijakelun ja perusterveydenhuollon piiriin ei ole toteutunut viimeisimmän korvaushoitoasetuksen (33/2008) tavoitteiden mukaisesti. Tässä artikkelissa tarkastellaan korvaushoidon työntekijöiden näkemyksiä siitä, mitkä tekijät vaikuttavat korvaushoitolääkkeen valintaan ja potilaan mahdollisuuteen siirtyä apteekkijakeluun. Artikkeli perustuu korvaushoitoyksiköiden työntekijöiden yksilö- ja ryhmähaastattelujen (N=40) ja työntekijöille suunnatun kyselyn (N=88) avovastausten teemakohtaisiin aineistolähtöisiin sisällönanalyyseihin.
Työntekijöiden haastattelujen perusteella korvaushoidon käytännöt ja lääkevalintojen perustelut vaihtelivat eri paikkakuntien välillä. Buprenorfiinia käytettiin yleensä korvaavana lääkkeenä kuntouttavassa ja metadonia haittoja vähentävässä korvaushoidossa, mutta näkemykset buprenorfiinin ja metadonin hyödyistä ja haitoista suhteessa toisiinsa ja eri potilasryhmiin vaihtelivat. Työntekijöiden mukaan metadonin käytön yleistymiseen korvaushoidossa on voinut vaikuttaa sen alhaisempi hinta.
Apteekkijakeluun siirtymisestä oli myönteisiä kokemuksia: se voi vahvistaa potilaan vastuunottoa omasta kuntoutumisestaan, vähentää hoitoon liittyvää stigmaa ja normalisoida hoitoa tavalliseksi sairaudenhoidoksi. Korvaushoitolääkkeen omavastuuosuus, jatkohoitopaikkojen vähyys, hoitoyksikön vaihtumiseen liittyvät tekijät sekä oheiskäytön jatkuminen ovat kuitenkin estäneet potilaiden siirtymisiä apteekkijakeluun.
Haastattelujen perusteella työntekijät kaipaavat valtakunnallisia hoitolinjauksia, mutta korostavat myös yksilöllisen hoidon merkitystä. Hoidon toteutuksessa tarvittaisiin edelleen yhtenäisempää näkemystä hoidon tavoitteista ja periaatteista. Hoidon kehittäminen osana laajempaa hoito- ja kuntoutusjärjestelmää vaatii sosiaali- ja terveydenhuollon toimijoiden suunnitelmallisempaa yhteistyötä. Uusi pistettävä pitkävaikutteinen lääke voi vähentää merkittävästi apteekkijakelun tarvetta.

We run the marathon of the Covid-19 pandemic, a novel and severe coronavirus (SARS-CoV-2) infection, an unprecedented crisis in modern medical times. This crisis has profoundly stressed health care systems worldwide by testing the limits of their capabilities, and abruptly changed the way of delivering care to our patients. Every aspect of the medical field has been heavily affected, and Oral-Maxillofacial Surgery services are no exception during these difficult circumstances. In addition, it posed a strict limit in the freedom of travel, and highly altered the global product supply chain, including personal protective equipment for the hospitals and health care workers. It gave rise to an economic crisis, very different from the previous experienced, with the economies trying to follow, modify and adapt their plans according to the virus spread, transmission and severity of regional clinical picture. Our social lives are altered with the introduction of distancing measures, and the wearing of face masks. All scientific meetings, globally and nationally, are cancelled, postponed or transformed to virtual events. The rapid adoption of digital technology revolutionized the delivery of healthcare and education.

This study aims to identify and assess population density that causes slums and physical effects on the environment in the Simpang Dago area. The methodology used is a qualitative research method on the object's condition by conducting a literature study and collecting related documents. The study was conducted with a case study in one area in the city of Bandung. The results showed that the achievement of comfort, safety, health, and mutual satisfaction is expected to help reduce population density impact in the Simpang Dago area. To achieve that goal, a study of population density impact on the quality of the physical environment. The solution of densely populated areas problem by relocating residents and providing affordable vertical housing by considering various aspects. The implication of this study's results is due to the dense population and houses' distance is too close; therefore residents around the Simpang Dago area must be concerned about their environment's cleanliness. In addition, not all population density gives negative impacts to the quality of an area's physical environment, depending on the residents' awareness.
An integrated approach to conservation of rare fern species using the example of Polystichum craspedosorum (Dryopteridaceae) in Amur Region, Far East оf Russia

Published: March 2022

Currently changes in the earth's vegetative cover have reached a planetary scale. The danger of extinction of species and ecosystems has become increasingly significant. Active measures must be undertaken to restore particular plant species and populations in order to minimise an ongoing loss of species. Polystichum craspedosorum is a cliff-dwelling fern, an East-Asian relict species whose northern range includes the Russian Far East. The northernmost population of this species, located in the Amur Region, is at risk of flooding by the Lower Bureya Dam. A series of measures were developed and implemented to conserve this plant. Plant individuals were translocated from the flood zone to other suitable habitats on the territory of the Amur Region. Monitoring has indicated that, after three years, the translocated plants have their usual seasonal rhythm, sporulation and the formation of gemmae. The survival rate at new places ranged from 60% to 88%. However, the final conclusions about the research efficiency can be made only after long-term monitoring for more than ten years. Cultivation of this species is being done in outdoor conditions at the Amur Branch of the Far Eastern Botanical Garden-Institute of RAS. The seasonal rhythm of cultivated plants was similar to the natural one in both spore production and gemma formation. The species can be assigned to cold hardiness zone 3 and it is promising for cultivation in the Amur Region. The possibility of cryopreservation of P. craspedosorum spores has been studied along with in vitro culture. After ultra-low temperatures, spores did not lose their viability and, thus, they can be stored in cryobanks for a long time. An integrated approach provides the maximum opportunity for the species conservation in nature and in culture. This integrated approach to conservation of a rare fern species is unique for Russia.

Published: March 2022

Salvia przewalskii Maxim. is an important Asian medicinal plant. The aim of the study was to investigate the reaction of seeds of this species to the priming and storage temperature. The germination, vigour and health of seeds were determined for untreated and osmoprimed diaspores, after harvest and 12 months of storage at 4 and 16°C. The seeds were primed in the polyethylene glycol (PEG) water solution with an osmotic potential of –0.8 and –1.1 MPa. It has been found that osmopriming of non-stored and stored seeds strongly reduced the time of germination. One-year storage of seeds both at 4 and 16°C caused statistically significant increase of the total number of germinating seeds, germination energy and capacity. The highest germination rate was found at the seeds stored at 16°C and primed with –0.8 MPa PEG solution.

Published: March 2022

In a view of the predicted drought that has appeared in recent years and water shortage in the growing season, which is getting worse every year, the problem of water retention in the soil and increasing its humidity becomes of exceptional importance. The field experiment was carried out in 2009–2012 on grey brown podzolic soil developed from loess formations covering the cretaceous marls with a granulometric composition corresponding to medium dusty loam. The aim of the study was to assess the impact of various species of cover crops and the method and date of mixing their biomass with the soil on the soil moisture in ploughless carrot cultivation. The experimental design included seven cover crop species (spring rye, common oat, common vetch, white mustard, lacy phacelia, buckwheat, fodder sunflower) and six kinds of soil tillage. The effect of cover crops and tillage on soil moisture was modified by the course of the weather and varied depending on the year of research, sampling date and soil layer. In spring, the highest layer of soil (0–20 cm) not cultivated before winter (NTz) accumulated the most water, and the least after pre-winter ploughing (Oz). In the 0–40 cm layer, the lowest humidity was in the soil ploughed before winter (Oz), and the highest after no-till (NTz) and after subsoiling before winter (GLz). The ridge cultivation performed in the spring caused the soil to dry out. In the remaining variants of no-ploughing tillage, soil moisture in the 0–40 cm layer was similar to that of conventional cultivation. Cover crops exerted a significant influence on the soil moisture in carrot cultivation at all test dates, increasing its moisture content compared to cultivation without cover crops. The rye cover crop had particularly favourable effect on the soil moisture.

Published: March 2022

Carrot culrivars ‘Bolero’, ‘Fayette F1’, ‘Flakke, Koral’, ‘Nantes’, ‘Perfekcja’ and ‘Sukces’ were grown in integrated and organic farming systems. The severity of Alternaria leaf blight and root diseases was evaluated at harvest and after five months of storage. Fungi were isolated from carrot roots. Disease severity was affected by the years of the study, farming system and cultivar. The severity of Alternaria leaf blight was lower in the integrated farming system than in the organic system. Carrots of cvs. ‘Bolero’ and ‘Fayette F1’ were healthiest. In both production systems, the symptoms of mixed rot (soft rot, Pectobacterium carotovorum subsp. carotovorum and Sclerotinia rot, Sclerotinia sclerotiorum), dry rot (Fusarium spp.), common scab (Streptomyces scabies), crater rot (Rhizoctonia carotae) and black rot (Alternaria radicina, A. dauci) were encountered sporadically, and their severity was low on carrot roots analyzed at harvest. Disease symptoms became more severe during storage, and they were more frequently observed on carrot roots in the organic farming system. Cultivars exerted varied effects on the severity of the analyzed root diseases. The fungal pathogens isolated from carrot roots confirmed the presence of disease symptoms.

Let $G$ be a group with identity $e$. Let $R$ be a commutative $G$-graded ring with non-zero identity, $S\subseteq h(R)$ a multiplicatively closed subset of $R$ and $M$ a graded $R$-module. In this article, we introduce and study the concept of graded $S$-1-absorbing prime submodules. A graded submodule $N$ of $M$ with $(N:_{R}M)\cap S=\emptyset$ is said to be graded $S$-1-absorbing prime, if there exists an $s_{g}\in S$ such that whenever $a_{h}b_{h'}m_{k}\in N$, then either $s_{g}a_{h}b_{h'}\in (N:_{R}M)$ or $s_{g}m_{k}\in N$ for all non-unit elements $a_{h},b_{h'}\in h(R)$ and all $m_{k}\in h(M)$. Some examples, characterizations and properties of graded $S$-1-absorbing prime submodules are given. Moreover, we give some characterizations of graded $S$-1-absorbing prime submodules in graded multiplicative modules.
Bone health assessment in haemophilic arthropathy: A single centre study from Kolkata, West Bengal, India
Authors: Mandal Prakas Kumar , Garg Malini , Chakrabarti Prantar , Bhowmik Amrita , Gantait Debasis , Dolai Tuphan Kanti
Published: March 2022

Background

Haemophilia has been associated with increased prevalence of low bone mineral density (BMD) which in turn may aggravate haemophilic arthropathy. Dual-energy X-ray absorptiometry (DEXA) is the gold standard for assessing BMD but is not widely available across India. Markers of bone turnover like bone-specific alkaline phosphatase (b-ALP) reflect osteoblastic turnover and may be surrogate to low BMD.

Aim

To evaluate how bone health in people with haemophilia (PWH) can be assessed by serum vitamin D3 and b-ALP level, correlated with the degree of arthropathy.

Methods

In this cross-sectional study, people with haemophilia A and B of all severities with arthropathy involving ≥3 joints were included. The number of joints affected by haemophilic arthropathy was recorded. Hemophilia Joint Health Score (HJHS) and Pettersson score were calculated for each patient. Levels of serum calcium, phosphorus, vitamin D3 and b-ALP were assayed in all cases.

Results

A total of 320 PWH were included; the majority (85%; 272/320) had severe haemophilia, 13.44% (43/320) moderate haemophilia and 1.56% (5/320) mild haemophilia. With increasing age, the number of joints involved increased significantly (r=0.2250, p<0.05). When adjusted for age, b-ALP was higher than normal for the majority of PWH (88.75%). Increased number of joints involved and severity of disease had a positive correlation with higher-than-normal b-ALP (adjusted for age) (r=0.2112, p=0.0001). A significant positive correlation was seen between Pettersson score and HJHS score (r=0.1126, p=0.04). There was no significant correlation between number of joints involved and serum vitamin D3 level across the whole cohort. (p<0.05).

Conclusion

PWH with severe disease and haemophilic arthropathy have higher than normal b-ALP, which in turn reflects increased bone turn over and low BMD. Hence, b-ALP may be a useful marker to help assess bone health in PWH, particularly in settings where access to DEXA scans is constrained.
Penciptaan Konserto Etude Tangganada Pentatonik untuk Pembelajaran Violin dan Orkestra
Authors: Garibaldi Pipin , Farant Brian
Published: March 2022

The Creation of Pentatonic Scale Etude Concerto for Violin and Orchestral Learning. This research aims to explain creating a musical work in the form of a violin etude in the form of a concerto. The concerto is arranged in a free pentatonic scale from traditional Javanese idioms: the lancaran and gangsaran rhythm. The concerto consists of one movement that contains etude material, namely learning the technique of playing the violin in a beautiful and exciting melody. The problem highlighted is students' difficulty learning etude for the violin, which is often considered complicated. In the learning process, students tend to be oriented towards violin music such as concertos, sonatas, or musical pieces (short works) compared to etude works. Therefore, it is important for creating the concerto etude to bridge the students' violin learning process, both for educative and performative dimensions. Creating the etude concerto in this traditional idiom is expected to foster student interest in learning to practice etude. The research was organized in several stages: document collection, observation, artistic, trial, and dissemination. The research/design method was taken from Reginald Smith Brindle (1986), i.e., Musical Composition and King Palmer Teach Yourself to Composed Music (1952). The method is as follows: listening to different music that is close to the research topic to find ideas, using the violin and piano to make melodic pieces, including double, triple, four-stop techniques, connecting, combining, developing synchronized melody pieces, rhythmic variations, rhythms, articulation variations, syncopations, rhythm figures, melodic decorations, harmonies, dynamic variations, and so on. The conclusion of the research on creating a concerto with one movement is more freedom to express ideas. The use of lancaran and gangsaran rhythms in a pentatonic scale to give the nuances of the Central Java region, turns out to be more nuanced with a Mandarin concerto. After being implemented, it turns out that this concerto is still quite difficult for learning violin 3.

The song is one of the teaching media used by preschool teachers around the globe. Indonesian preschool teachers face a rising problem: the government regulates a standard curriculum where the educational song is compulsory. Yet, there is no concern to facilitate and fill in the absence of children's educational songs. This study aims to unveil the creative process of non-music education graduate teachers in composing educational songs as required by the curriculum. This study employs a qualitative design based on a case study of thirty-three teachers from eleven different preschools in Semarang, Central Java, Indonesia. The researchers analyze the preschools' curriculum, teachers' interviews, field observations, and documentation. The findings show that teachers can use their creativity to create songs with educational messages projected in a collective poetry singing performance. Poetry singing allows students' aesthetic skills development through continuous song probe and response between teachers and students.
