Unexpected discovery of 7-Methyljuglone (Ramentaceone) in several Australian sundews
Authors: Schlauer Jan , Hartmeyer Siegfried R. H. , Hartmeyer Irmgard
Published: February 2022

Naphthoquinones are characteristic constituents that have been detected in numerous plant families. There are at least four fundamentally different biosynthetic routes that lead to the naphthoquinone skeleton. Some naphthoquinones are formed via the acetatepolymalonate (= polyketide) pathway, and plant families notoriously known for containing such acetogenins are Iridaceae, Ebenaceae, Plumbaginaceae, Droseraceae, Nepenthaceae, Drosophyllaceae, Dioncophyllaceae, and Ancistrocladaceae. While all these families include species that form plumbagin (= 2-methyljuglone), its regioisomer 7-methyljuglone (= ramentaceone) has so far only been detected in Ebenaceae, Nepenthaceae, and Droseraceae.
Quantification of growth benefit of carnivorous plants from prey
Authors: Adamec Lubomír
Published: February 2022

The growth of carnivorous plants is usually limited or co-limited by shortage of available mineral nutrients N, P, and K in barren soils or waters. Carnivorous plants capture animal prey, absorb mineral nutrients from digested prey, and partly overcome the nutrient limitation. Therefore, prey capture leads invariably to marked and significant growth increase as the main ecophysiological benefit of carnivory. Here, a novel functional-ecological approach of how to quantify growth benefit efficiency of carnivory is explained. It expresses plant growth increase due to prey catching or feeding per amount of N or P or K theoretically absorbed from prey (or applied in mineral solution onto the traps) in growth experiments.

“Go Out” and “Come Back”: Illusion of Return in A Streetcar Named Desire
Authors: Wang Lin
Published: February 2022

A Streetcar Named Desire exhibits dynamic spatial movement, featured by Stella’s repetitive return of “going out” and “coming back.” The movement reveals her desire to escape the undesirable parts of her marriage, e.g., vulgarity, poverty, and violence. Yet her inevitable “coming back” is because she depends on Stanley for survival. In terms of space, Stella and Stanley run out on the street, which privatizes the street and publicizes the home. Blanche’s physical intrusion causes crises to the marriage, and she tries to point out the undesirable truth of it. So the Kowalskis respond with different actions, which ultimately bring Blanche to her destruction. This choice traps the Kowalskis in the eternal loop of “going out” and “coming back,” and they continue to live in an illusion of progression, as they are caught in the same state.

Ruang gerak yang sempit akan sulit untuk menentukan penempatan site layout. Di dalam perencanaan site layout, sepatutnya memperhatikam fasilitas yang dapat menghemat pemakaian ruang bangun. Hal ini memerlukan kecermatan dalam penempatannya karena berpengaruh pada produktivitas kerja. Semakin besar area yang digunakan dalam penempatan site layout maka perjalanan antar fasilitas juga semakin banyak memakan waktu. Tujuan pembuatan alternatif site layout ini adalah untuk memperoleh site layout yang optimal. Dalam studi ini dilakukan perencanaan site layout dengan Traveling Distance (TD) dan Safety Index (SI) atau bisa disebut multi objectives function sebagai acuannya yang didapatkan setelah menghitung jarak antar fasilitas, frekuensi perpindahan/perjalanan pekerja, dan angka keamanan. Nilai traveling distance sebesar 26963,8 dan nilai safety index sebesar 1400 pada perencanaan site layout alternatif kesatu. Pada alternatif kedua nilai traveling distance sebesar 24757,5 dan nilai safety index sebesar 1178.

Distinguishing between accounts of the A/A'-distinction: the view from Argentinian Spanish Clitic Doubling
Authors: Fong Suzana
Published: February 2022

The A/A'-distinction underpins case, agreement, and binding properties of moving DPs. It also determines possible movement paths (cf. the Ban on Improper Movement). Van Urk (2015) and Safir (2019) take this distinction not to be a primitive of the grammar; rather, these authors seek to derive the A/A’-distinction from independent principles of the grammar. In both approaches, syntactic positions are not inherently A or A’. Rather, independent and more general properties of the grammar determine, as a byproduct, the nature of the movement that passes through these positions. While these approaches differ in which grammatical components they derive the A/A’-distinction from, both are able to explain the properties that it is based on (e.g. weak crossover, reconstruction, etc). Another similarity is that both approaches allow for a flexible definition of syntactic positions. I will argue that, despite these similarities, we can empirically adjudicate between these two theories. Specifically, Di Tullio et al.’s (2019) analysis of clitic doubling in Argentinian Spanish will be shown to be compatible only with Van Urk (2015).
On the prosodic realization of Spanish ¿no?-tags from a pragmatic perspective
Authors: Gazdik Anna
Published: February 2022

The aim of this paper is to report on an empirical study investigating the prosodic realization of the Spanish tag ¿no? added to host clauses with different clause types, realizing various speech act types. Although ¿no? is commonly assumed to display a rising contour, we show that there are level and falling contours over the tag as well, even though rising contours are indeed dominant. The observed tendencies confirm the hypotheses that the contour over the tag is influenced both by the clause type of the host clause (¿no? in exclamatives and interrogatives display wider tonal excursions, and is more often realized with a rising contour than imperatives and declaratives). On the other hand, the type of the modified speech act also plays a role: commissives show more rising contours than expressives, directives and assertives. On the pragmatic side, we assume (with Kiss (2018)) that the function of the tag is the attribution of the whole discourse move to the addressee. In addition, we suppose that the rising contour over the tag signals a call on the addressee to interpret the whole discourse move as a meta-question on the attribution of the realized speech act to the addressee.
A Proposal of Seismic Index for Existing Buildings in Indonesia using Pushover Analysis
Authors: Kurniawandy Alex , Nakazawa Shoji
Published: February 2022

Indonesia has often suffered major earthquake damage over the past 50 years. There are thousands of buildings in earthquake-prone regions that still need seismic evaluation and rehabilitation. One method of evaluating the seismic performance of an existing building is by assessing it using the Japanese seismic index for structures. A basic seismic index can be calculated based on the strength and ductility criteria. The strength and ductility performance of a structure can be obtained by pushing a building until it reaches its maximum deformation capacity. This paper describes a proposal to obtain a basic seismic index using pushover analysis. Its adjustment to determine a seismic demand index by considering seismic hazard in Indonesia was carried out using the capacity spectrum method. Two existing buildings in Indonesia were evaluated. The evaluation result indicated that both buildings were in safe condition. The proposal of the seismic index method can be useful in determining the performance index of existing structures. The ductility index can also be used to estimate the response modification factor of a structure.
Integrated Magnetotelluric (MT), Gravity and Seismic Study of Lower Kutai Basin Configuration
Authors: Irawati Selvi Misnia , Hidayat Hidayat , Wijanarko Edy , Grandis Hendra
Published: February 2022

This work describes a subsurface basin configuration of the Lower Kutai Basin (hereinafter LKB) in East Kalimantan, Indonesia, as inferred from combination of magnetotelluric (MT), seismic, and gravity data. LKB is structurally controlled mainly by the Samarinda Anticlinorium extending in a NNE-SSW direction and is one of the most prolific hydrocarbon basins in Indonesia. The phase tensor analysis of MT data from most stations and frequencies exhibited a 2D character with a relatively low skew (-3° < β < 3°).  The geo-electrical strike direction was estimated at N30°E, which is in good agreement with the regional geological strike with a NNE-SSW direction. 2D MT inversion modeling was performed to infer the subsurface resistivity distribution associated with LKB’s configuration. From the integration of MT, seismic and gravity models it was shown that LKB’s configuration is composed mainly of sandstone, black shale, claystone, and basement rocks. The conductive zones of the MT models are associated with thermal alteration of black shale, which changes its mineralization, leading to lower resistivity. Hence, the black shale may be interpreted as potential hydrocarbon source rock in LKB.

Published: February 2022

Land subsidence is a geomorphological event that affects Earth’s structure and physiognomy. This phenomenon occurs when the groundwater volume changes and results in the movement and sinking of sediment. Several studies have been conducted to identify major causes or factors that may lead to land subsidence. It was found that land subsidence intensity is influenced by several factors, i.e. terrain slope and aspect, land use, soil moisture content, and distance to a river. Population density contributes to continuous changes in land use. Deep investigation of factors that contribute to land subsidence such as population density is important. This study investigated the relationship between land subsidence and population density contributing to continuous land-use changes. The study area was a highly populated slum area along the Musi River in Palembang, Indonesia. Factors that have high contribution to land subsidence were considered in developing a land subsidence susceptibility map. Susceptibility analysis was done using the Analytical Hierarchy Process (AHP) method. Land subsidence features were associated with slum features and the result revealed a significantly high correlation (r = 0.844) between actual land subsidence areas and the developed susceptibility map.
Evaluasi Penggunaan Produk Suplemen Pada Atlet Taekwondo Jawa Barat
Authors: Novian Geraldi
Published: February 2022

Produk suplemen sudah menjadi hal yang lazim digunakan oleh para atlet untuk membantu performa olahraga. Namun sayangnya, tidak semua atlet memiliki pengetahuan yang baik tentang penggunaan produk suplemen. Bahkan, tidak sedikit juga atlet yang cenderung salah kaprah akan penggunaan supplement products. Hal ini akan sangat mengkhawatirkan jika terus menerus dibiarkan karena akan berpengaruh pada performa olahraga atlet itu sendiri. Sehingga tujuan dari penelitian ini adalah untuk mengetahui penggunaan dan pengetahuan tentang produk suplemen pada atlet taekwondo (TKD). Penelitian ini menggunakan metode deskriptif dengan memberikan kuesioner kepada sampel sebanyak satu kali. Sampel dalam penelitian ini adalah 18 atlet taekwondo provinsi Jawa Barat yang diambil menggunakan teknik total sampling dari populasi. Hasil penelitian menunjukkan bahwa 100% atlet putra dan putri menggunakan produk suplemen. Jenis produk suplemen yang digunakan sampel adalah protein powder (90%), creatine (10%) untuk atlet putra, sedangkan protein powder (75%), vitamin (12.5%), dan mineral (12.5%) untuk atlet putri. Diketahui bahwa informasi terkait supplement products pada atlet putra 100% diperoleh dari pelatih dan pada atlet putri 62.5% diperoleh dari pelatih, 12.5% diperoleh dari pharmacist dan 25% diperoleh dari yang lain. Alasan terbesar atlet putra (70%) dan putri (50%) menggunakan produk suplemen adalah untuk meninggkatkan performa olahraganya, alasan lainnya adalah untuk membentuk tubuh (30%) atlet putra dan (25%) atlet putri dan meningkatkan imunitas tubuh (25%) atlet putri. Penggunaan produk suplemen pada atlet TKD memiliki tujuan yang baik, namun sangat disayangkan mayoritas atlet belum memiliki pengetahuan yang baik terkait penggunaan produk suplemen. Maka dari itu, penting bagi atlet memiliki pengetahuan yang baik terkait penggunaan produk suplemen dan juga melakukan evaluasi secara berkala agar tujuan penggunaan bisa tercapai lebih maksimal.

: The potential for cancer cells to grow and to metastasize depends on complex interactions between inflammatory signals and pathways, immune cells, and elements of the stromal tissue in which they invade. Related to the nature of many cancers, the probability of recurrence can potentially be quite high for some patients. Immunology, lifestyle modifications, timing of disease, genetics, age, gender, and race are only a handful of ways the likelihood of cancer recurrence can be influenced. The quantity, or density, of certain immunological cells or factors, plays a role in the propagation of cancer cells. Opioids are often used in cancer patients for acute postoperative and chronic pain management. While they can produce significant pain relief, the type of analgesic utilized is important, as it may influence cancer propagation. In this regard, certain opioids have been found to increase T regulatory cells while suppressing NK cell function. Morphine may promote tumor neovascularization and expansion. Fentanyl administration significantly diminishes NK-cells and CD8+ cytotoxic T-cells. In a recent meta-analysis, propofol-based anesthesia improved both cancer-free survival and overall survival. COX inhibitors have also shown promise in persevering cancer immune function, as in literature involving ketorolac and celecoxib. In summary, inhaled anesthesia and opioids may contribute to a pro-tumor metastasis environment also known as cancer propagation; whereas propofol and COX inhibitors may provide a better alternative to reduce cancer recurrence and propagation.

Published: February 2022

Background: Hearing loss (HL) is the most prevalent sensory disease in humans. HL is among the most clinically and genetically heterogeneous disorders. Pathogenic variants in GJB2 are the principal cause of HL in many populations. Therefore, GJB2 analysis should be considered as the first step for HL. Objectives: This study aimed to find causative variants in the GJB2 gene in 75 unrelated Iranian patients who suffered from Autosomal recessive non-syndromic hearing loss (ARNSHL). Methods: Peripheral blood samples were used for genomic DNA extraction. PCR-direct sequencing was performed to detect GJB2 mutations. Results: In this study, thirty-four chromosomes (21.33%) carried GJB2 mutations. In general, 10 variants were detected among 19 patients. Seven cases were homozygous for c.35delG; (p.Gly12Valfs*2), two were homozygous for c.71G>A; (p.Trp24*), two were homozygous for c.358-360delGAG (p.Glu120del), and two were homozygous for c.-23+1G>A mutation. One patient was a compound heterozygote for c.35delG and c.-23+1G>A mutations, and another patient with compound heterozygosity for c.290dupA and c.235delC mutations were determined. Four patients carried a mono-allelic variant in the GJB2 including c.126G>T; (p.Glu42Asp), c.23C>T; (p.Thr8Met), c.445G>A; (p.Ala149Thr) and c.269T>C; (p.Leu90Pro). Accordingly, c.35delG mutation was the most common variant in this study. Conclusions: Finding common variants of HL mutations in different populations can elevate the diagnostic value of molecular testing in the screening of affected individuals, and can improve counselling to minimize the risk of having affected offspring for at-risk couples.

Objectives To evaluate the association of obstructive sleep apnea (OSA) with high-sensitivity C-reactive protein (CRP) and fibrinogen levels and to assess the effect of short-term therapy using continuous positive airway pressure (CPAP).

Material and Methods A prospective, open-label, controlled trial was conducted among clinically referred patients at risk for OSA undergoing diagnostic polysomnography (PSG). After PSG, the patients were divided into 3 groups: OSA treatment group (TG) (n=21), untreated OSA group (UOG) (n=19), and non-OSA healthy control group (HCG) (n=24). CRP and fibrinogen levels were measured at baseline and one month after treatment. Repeated-measures (RM) ANOVA and ANCOVA were used to compare changes in CRP and fibrinogen levels among the three groups by analyzing between-subject and within-subject effects as functions of time and adjusting for significant covariates.

Results At baseline, OSA subjects had significantly higher CRP [t(52.37)=-2.46, p=0.02)] and fibrinogen levels [t(57)=-2.00, p=0.05)] than HCG subjects. No significant differences in CRP levels [(F(2,58)=2.29, p=0.11)] or fibrinogen levels [(F(2, 58)=1.28, p=0.29)] emerged between TG and HCG subjects after adjusting for the pretest levels.

Conclusion CPAP therapy for one month does not affect CRP and fibrinogen levels among moderate-to-severe OSA patients. However, OSA is associated with elevated levels of these inflammatory biomarkers.

Objective To analyze the relation among insomnia, excessive daytime sleepiness and the excessive use of technologies in medical students.

Methods The study was approved by the Local Ethics Committee of the institution. Students from the 1st and 2nd year of medical graduation students participated. Three questionnaires were used: Sleep Time-Related Information and Communication Technology, Insomnia Severity Index and the Epworth Sleepiness Scale. The data were described and compared by gender and year of graduation by the Students T Test, and correlated to the use of technology, insomnia and excessive daytime sleepiness by Pearsons Correlation (adopted the significance level of p <0.05).

Results 106 students (41 male) participated, expressing perception of insomnia in 76.4%, 34% with excessive daytime sleepiness, and 38.3% had a high use of technology related to sleep. There was a correlation between the use of technologies both with insomnia (r = 0.393; p = < 0.001), as well as with excessive daytime sleepiness (r = 0.228; p = 0.019).

Conclusion An important frequency of insomnia was found associated with the excessive use of technologies at the bed, with repercussions of daytime sleepiness. This demonstrates the importance of actions to raise awareness and education about correct sleep hygiene in medical students.

Objective To evaluate the subjective sleep pattern in hospitalized patients.

Methods This is a cross-sectional design developed with 230 patients in a university hospital in northeastern Brazil from September 2017 to March 2018. We included patients 18 years old or older, hospitalized for a minimum of 48 hours and a maximum of five days, with stable clinical conditions and preserved guidance. For data collection, a structured questionnaire was used and the subjective sleep pattern was assessed using Visual Analog Sleep Scales. Univariate and bivariate statistics were calculated using IBM® SPSS® software, version 23.0.

Results In the hospitalization, the Disorder, Effectiveness, and Supplementation scales reached scores of 208.7 points, 353.8 points, and 62.9 points, respectively. The clinical characteristics that interfered with sleep were the practice of regular physical activity (p = 0.024) and a higher body mass index (p = 0.033). We also observed statistically significant differences between VAS scores and factors influencing sleep.

Conclusion There was a certain level of sleep disturbance during the hospitalization period, and consequently the need for sleep supplementation during the day. We also observed that some factors negatively influenced the quality of hospital sleep.

Published: February 2022

Objective The purpose of this study was to compare the duration of sleep and nap patterns between children in private kindergartens and those in a tabika-transit facility, in Malaysia.

Methods The sleep duration of children aged 3-6, who attended either a kindergarten or a childcare transit facility (tabika-transit in Malay) was investigated. Observational sleeping records were maintained for 24 hours, over 14 consecutive days. A self-administered questionnaire for caregivers investigated the children’s lifestyles. Naps were optional at kindergartens but mandatory at the tabika-transit.

Results Of 35 participating children, data from 33 were analyzed. All respondents belonged to the Malay ethnicity, with 16 boys (48.5%) and 17 girls (51.5%). The average age of the children was 5.4 years; 11 of them were from kindergartens and 22 from a tabika-transit. The children slept longer and woke up later on weekends than on weekdays. There was a significant difference in the naptaking rate between the two groups; it was 100% in the tabika-transit, and 30% in the kindergartens during weekdays. However, on weekends, 19 of 22 tabika- transit children did not nap on any of the days (86.4%). The kindergarten group’s naps showed no outstanding differences between weekdays and weekends. Concerning the bedtime and wake-up times, no differences were found between the two groups.

Discussion During weekdays, all children in the tabika-transit took naps, whereas one-third of them did in the kindergartens. Larger study is needed to assess how this mandatory napping style affects children’s lifestyle and development.
Poor sleep is associated with sensation-seeking and risk behavior in college students

Published: February 2022

Objective The current study examines the relationship between sleep duration and variability with sensation- seeking and risky behaviors in a sample of Iranian undergraduate students.

Methods The participants in this study were 385 undergraduate students in Tehran. To collect data, we used the Sensation Seeking Scale, Risk Behavior Scale, and two questions related to sleep duration and sleep variability.

Results The results showed a positive relationship between sleep deprivation and irregular sleep schedule with sensation-seeking and risk behavior tendencies in students.

Discussion This association could point to an indirect impact of sleep deprivation on sensationseeking and risk behavior, for example, by altering brain regions responsible for self- control.

Representación lexicográfica de la equivalencia sémica en un diccionario digital de locuciones del español y del italiano
Authors: Dal Maso Elena
Published: February 2022

El presente artículo aborda la representación lexicográfica de la equivalencia sémica en un corpus de locuciones nominales del español y del italiano. A este fin, se ilustran algunas fichas confeccionadas para el repertorio bilingüe bidireccional español/italiano italiano/español del Diccionario fraseológico multilingüe digital (DFMD), en curso de elaboración en la Universidad Ca’ Foscari de Venecia. Al existir binomios fraseológicos cuyos referentes extratextuales comparten el mismo perfil sémico (p. ej., caballo de Troya [+hum, +obj] y cavallo di Troia [+hum, +obj]) y, a un tiempo, otros pares que manifiestan discrepancias (piénsese en hueso duro/difícil de roer [+hum, +obj] y sus equivalentes osso duro [+hum] y (bella/brutta) gatta da pelare [+obj]), en las entradas elaboradas se propone un tratamiento de la correspondencia sémica capaz de guiar a los usuarios del diccionario en la selección del equivalente más adecuado en cada caso.
A Comparative Study of Dietary Related Zero-waste Patterns and Consumer Responses Before and After COVID-19
Authors: Park In-Hyoung , Park You-min , Lee Cheol , Sun Jung-eun , Hu Wendie , Chung Jae-Eun
Published: February 2022

This study uses text mining compares and contrasts consumers’ social media discourses on dietary related zero-waste movement before and after COVID-19. The results indicate that the amount of buzz on social networks for the zero- waste movement has been increasing after COVID-19. Additionally, the results of frequency analysis and topic modeling revealed that subjects associated with zero-waste movement were more diversified after COVID-19. Although the results of a sentiment analysis and word cloud visualization confirmed that consumers’ positive responses toward the zero-waste have been increasing, they also revealed a need to educate and encourage those who are still not aware of the need for zero-waste. Finally, consumers mentioned only a small number of companies participating in zero-waste movement on SNS, indicating that the level of active involvement by such companies is much lower than that of consumers. Theoretical and educational implications as well as those for government policy-making are considered.
The Embodied Work of Repairing-for-Teasing in Everyday L2 Talk
Authors: Lilja Niina , Eskildsen Søren Wind
Published: February 2022

This paper focuses on participants’ embodied conduct in the service of action ascription in teasing environments. The teasing activity is sequentially organized as an other-initiated repair sequence in which the other-initiations of repair (OIRs) are used as vehicles for carrying out the teasing actions (see also Schegloff, 1997, 2007; Rossi, 2018). The analysis shows that the double-barreled OIRs are designed as multimodal action packages in which the verbal part is delivered in a serious manner and combined with embodied conduct that typically characterizes repair environments, such as head turns and tilts, forward-leaning, and gestural holds, but produced in exaggerated or pretended manner. The embodied exaggeration and performed character are the key elements contributing to action ascription in teasing environments.
Multimodal Gestalts in Reformulating Practices in Language Cafés
Authors: Kunitz Silvia , Majlesi Ali Reza
Published: February 2022

This study focuses on the multimodal gestalts (Mondada, 2014) in unsolicited other-reformulations produced by L1 speaking volunteers in language cafés where visitors practice Swedish with volunteers from the local community. The unsolicited other-reformulations in our collection: (a) act as clarifications of what was said before, and (b) highlight (Goodwin, 2018; Majlesi, 2022/this issue) lexical items used in the prior turn, thereby orienting to them as learnables (Majlesi & Broth, 2012). Our findings suggest that multimodal gestalts in other-reformulations make parts of the original turn more visible and transparent for L2 speakers, and therefore make such parts salient for language learning.
