A novel miniature transposon-like element discovered in the coding sequence of a gene that encodes for 5-formyltetrahydrofolate in wheat
Authors: Keidar-Friedman Danielle , Domb Katherine , Kashkush Khalil
Published: May 2019

Background: Transposable elements (TEs) comprise over 80% of the wheat genome and usually possess unique features for specific super-families and families. Nevertheless, the role of TEs in wheat evolution and reshaping the wheat genome remains largely unclear. Results: In this study, we discovered a miniature (307 bp in length) TE-like sequence in exon 6 of a gene that encodes for 5-formyltetrahydrofolate, in two accessions of wild emmer wheat (T. turgidum ssp. dicoccoides) and has interfered with the gene translation by creating a shorter reading frame as a result of a stop codon. The sequence that was termed Mariam, does not show any structural similarity to known TEs. It does not possess terminal inverted repeats (TIRs) that would allow us to assign this element to one of the TIR DNA super-families, and it does not possess characteristic features of SINE, such as a Pol-III promotor or a poly-A tail. In-silico analysis of five publicly available genome drafts of Triticum and Aegilops species revealed that Mariam element appears in a very law copy number (1- 3 insertions) in diploid wheat species and ~12 insertions in tetraploid and hexaploidy wheat species. In addition, Mariam element was found to be unique to wheat, as it was not found in other plant genomes. The dynamic nature of Mariam in the wheat genome was assessed by site-specific PCR analysis and revealed that it retained activity in wild emmer populations in a population-specific manner.
Conclusions: This study provides additional insight into the evolutionary impact of TEs in wheat.

Authors: Ma Kelong , Zhang Shengxiang , Peng Daiyin , Wang Chenkai , Shi Yuanyuan , Yang Qingshan , Wu jiawen , Huang Luqi
Published: May 2019

Background: MicroRNAs (miRNAs) are a group of endogenous small non-coding RNAs with important roles in plant growth, development, and metabolic processes. Polygonatum cyrtonema Hua (P. cyrtonema) is an important Chinese traditional medicinal herb with broad pharmacological functions, and polysaccharides are the main biological substance accumulated in the P. cyrtonema rhizome. However, regulation of the process of polysaccharide biosynthesis in P. cyrtonema remains largely unknown.
Results: To elucidate the miRNAs and their targets involved in polysaccharide biosynthesis in P. cyrtonema, four small RNA libraries were constructed from flower, leaf, rhizome, and root tissues and sequenced. A total of 69 conserved and 5 novel miRNAs were identified, of which 6 miRNAs (miR156a-5p, miR156f-5p, miR395a_5, miR396a-3p, miR396g-3p, and miR397-5p_1) were down-regulated and 7 miRNAs (miR160, miR160h_1, miR160e-5p, miR319b_1, miR319_1, miR319c-5p_3, and miR319c_1) were up-regulated in rhizomes compared with flower, leaf, and root tissues. Bioinformatics analysis showed that the predicted targets of these miRNAs were mostly transcription factors and functional genes enriched in metabolic and secondary metabolite biosynthetic pathways, and 7 genes and their paired miRNAs were identified in carbohydrate metabolism. qRT-PCR expression analysis demonstrated that 6 miRNAs and their targets involved in carbohydrate metabolism were existed a negative correlation in. P. cyrtonema tissues. MiR396a-3p and one of its target genes, abfA, were possibly involed in polysaccharide biosynthesis pathway.
Conclusions: This is the first report on the identification of conserved and novel miRNAs and their potential targets in P. cyrtonema, thus providing molecular evidence for the role of miRNAs in the regulation of polysaccharide biosynthesis in P. cyrtonema.
Guest Workers – From Their Own Perspective. Narratives About Life and the Socio-Economic Position of Migrant Workers
Authors: Antonijević Dragana , Banić Grubišić Ana , Krstić Marija
Published: May 2019

Based on fieldwork conducted in Eastern Serbia (Knjaževac and Kučevo with surrounding regions), this paper analyzes the life stories of migrant workers as material crucial for anthropological and folkloristic research into experiences, values and attitudes of the members of a certain culture. The term “guest worker” (ser. gastarbajter, i.e. ger.gastarbeit) was used to designate temporary migrants who served as labor at the time of the reconstruction of Western Europe after World War II. A large number of migrant workers decided to stay in the host countries, and work migrations are still a common occurrence today. Based on the life stories of guest workers, in this paper we will attempt to map out the specific characteristics of different waves of migration. While all the waves of migration had a common cause – the desire for a better life and material stability –  there were certain additional motives which depended on the political and socio-economic conditions in the home country. Furthermore, we are interested in the process of acculturation in different host countries, focusing on the differences in social policy regarding immigrants, the geographic distance from Serbia and the number of compatriots in the host country. Finally, we will address the narratives of guest workers who have returned, focusing on the reasons they decided to come back to their home country and the ways in which they settled down after their return.
Airway management in hospital. Russian Federation of anesthesiologists and reanimatologists guidelines (second edition, 2018)
Authors: Andreenko Aleksander A. , Dolbneva E. L. , Stamov V. I.
Published: May 2019

The review presents the clinical guidelines of the Federation of Anaesthesiology and Resuscitation specialists of Russia, revised in 2018. The recommendations are based on a review of publications and modern international guidelines of the Difficult Airway Society (DAS, 2015), American Society of Anesthesiologists (ASA, 2013), the European Society of Anesthesiologists (ESA, 2018).
“Difficult airways” are encountered relatively infrequently in modern anesthesia practice, but if it is impossible to ensure adequate oxygenation of patients, they lead to post-hypoxic brain damage or circulatory arrest. Current requirements for patient safety during anesthesia determine the need for a thorough assessment of patients before surgery, identification of prognostic signs of difficult ventilation through a face mask or supraglottic airway device, difficult laryngoscopy and tracheal intubation, difficult cricothyrotomy. As a result of the examination, the anesthesiologist is obliged to formulate the main and reserve action plan, prepare the necessary equipment, and involve specialists if necessary.
The recommendations provide evidence of the effectiveness of modern devices for ventilation and tracheal intubation. Algorithms for making decisions and actions in various situations with predictable and unpredictable “difficult airways” in patients with different risks of aspiration are proposed. An algorithm for preparing, predicting possible complications and performing extubation of the trachea is also proposed. The recommendations presented in the review are aimed at achieving the goal of increasing patient safety during general anesthesia by reducing the risk of developing critical disorders of gas exchange due to airway management problems.

Published: May 2019

Chronic pain after a laparoscopic cholecystectomia represents a considerable problem. One of the directions of prevention and treatment of a chronic pain syndrome are attempts of use of various adjuvants from which the most promising results showed antidepressants, antikonvulsant, antagonists of NMDA of receptors, α2-агонисты and local anesthetics.
The purpose of this single center randomized, and placebo-controlled study was to evaluate the impact of IV lidocaine on CPPS (Chronic Postoperative Pain Syndrome).
Materials and Methods. Following approval of the study protocol by the University ethics committee 96 patients were randomized into 2 groups for participation in this study. All patients were ASA class II and III, aged 21 years and older and undergoing elective laparoscopic cholecystectomy under general anesthesia. All patients were randomly allocated into 2 groups of equal size to receive either lidocaine infusion (Lidocaine group), or 0.9 % sodium chloride infusion (Control group).
Results. The incidence of CPPS after 3 months was significantly lower in the Lidocaine group than in the Control group (10 vs 37,3 %, Fisher’s Exact Test P = 0.0069) with an overall incidence of 29.2 %, and after 6 months 18.3 % (16 vs 19.3 % accordingly, Fisher’s Exact Test P = 1.0). Date evaluation of PRI NWC (total and in each of 3 category) 6 month and 12 month after surgery with Fisher’s Exact Test and t Mann Whitney test, could not find any difference in groups. Conclusion. No differences between control group and lidocaine in 6 and 12 months were found after surgery.

Published: May 2019

The article presents some results of an archaeological researches conducted at the northern city wall in the seaside part of Derbent outside the medieval shakhristan. The soundings (No. 26–29) revealed layers of various geneses and provided new data on the historical topography of the medieval town. The obtained data point at some cultural layers of Pre-Mongol period (X – early XIII century) outside the shakhristan (soundings No. 26–28). It was period of flourishing for the medieval Derbent when the city occupied the territory of architecturally allocated shakhristan and when the near and far agricultural areas was actively used. These materials also confirm the earlier obtained data that the active life of the city ceased in the second quarter of the XIII century due to Mongol invasions. At the same time, excavations revealed some layers related to the late Sasanian period and connected with the large-scale construction of a stone defensive wall in the middle of the VI century (soundings No. 26, 27) and an adobe defensive wall built in the middle of the V century (sounding No. 27), which completely closed the Derbent pass.

On the western border of the surveyed site, six Muslim stone sarcophagus-shaped sepulchral monuments of the XI–XII centuries were found in the modern ditch, as well as some stone plates from the destroyed cists. The sarcophagi are the most extreme east monuments within the medieval necropolis of Derbent, and they act as evident confirmation to Adam Olearius’ engraving (1637 AD) that depicted Derbent and its extensive northern cemetery with such monuments.

Authors: Gaus K. O. , Riabova M. Yu.
Published: May 2019

The paper presents such basic units of cognitive linguistics as frame, script, and concept from the perspective of theories and concepts introduced by leading scientists. It introduces some results of the construction of the nominative field of the concept "threat". The research featured the concept "threat" in the political mass media discourse as a universal means of speech influence. The lexical units under analysis belonged both to the core and periphery of the nominative field of the concept. The authors defined the most frequent scripts of the concept "threat", both general and particular, e. g. direct threat, indirect threat, explicit threat, and implicit threat. Their structural characteristics were based on the examples from D. Trump’s statements. The most characteristic attributes of the concept "threat" proved to be verbs of destructive semantics, nuclear lexemes of the concept field, etc. This article reflects the features of the verbal representation of the concept "threat", as well as the purposes of the speech act of threat as a universal leverage in the modern political communication.

The research features the speech stereotype at the stage of its formation. The author observes the way stereotype of socially approved behavior are formed with the help of speech stereotypes united by the concept of "product waste". An analysis of "gaspillage alimentaire" social advertising revealed some speech stereotypes, stereotyping mechanisms, as well as the way they influence the recipient of the social advertising discourse. The author states the key role of the speech stereotype that address the recipient to the existing models of behavior and in the formation of new models that are in demand in the French society. The results of the research contribute to a better understanding of the speech behavior in different cultures and can be used in the courses of cultural linguistics, French language stylistics, and discourse analysis.
Propositional-Frame Approach to the Description of Families of Russian Cognate Words as a Representation of Mental Discourse
Authors: Kalyuzhnaya T. V.
Published: May 2019

The research features families of cognate words in the Russian language as a dynamic phenomenon. Frame and proposition were adopted as the basic units of representation of word families. The study focused on derivatives with the borrowed formants -атор/-тор (-ator/-tor). Most of the propositions with -атор revealed a high degree of typification. This typification of propositions undergoes changes under the influence of the tendencies of the Russian linguistic system and as a result of assimilation. The mutation occurs both by changing the actants in the proposition, as well as by expanding the actant paradigm and the appearance of new members in the proposition. Assimilation results in polysemic potency derivatives. Occasional meanings of the analyzed derivatives form a new family with a typified frame structure. The nests are divided into propositions typical for similar families, with the same limited set of actants. The propositional-frame approach to the description of the families of cognate words makes it possible to express the knowledge of native speakers about the world, as well as to represent the epistemological basis of mental discourse.
Postmodernist Play within Different Text Levels in There But For The by Ali Smith
Authors: Lushnikova G. I. , Osadchaia T. Iu.
Published: May 2019

Postmodern play is one of the important characteristics of modern fiction; it often acts as a text-forming element of the literary work. Literary play is manifested within different text levels and literary discourse strategies: the narrative, composition, imagery, diction, narrative temporality and modality, the technique of metanarrative. The present paper features the poetics of play within different text levels and literary discourse strategies in the novel by contemporary Scottish writer Ali Smith "There But For The". At the level of the novel’s narrative, the play manifests itself in the confusion of reality and fantasy, imagination and actual memory in the characters' internal speech. At the level of composition, the author plays with the readers, giving them an opportunity to find some "key" that will connect the four chapters of the novel and the prologue; the characters and connections between them are sometimes also a mystery. Within the literary strategy of temporality, the following play elements are presented: the contrast between serious reasoning about Time and humorous comments and thematically related pieces of poetry; nonlinear narration; description of events which take place in different time periods in a short context. Within the literary strategy of modality, we can trace the author’s play with the reader and the effect of defeated expectancy. The technique of metanarrative also contains elements of the play: the literary and stylistic means used in the novel are explained both in a serious and a joking manner. The diction of the novel is characterized by usage of stylistic devices of different language levels, their function being that of the play: oxymoron, zeugma, chiasm, holophrasis, different types of morphological repetition, and pun. The results of the study suggest that the introduction of elements of a play into the novel at its different levels makes a sharp contrast with the existential themes of the work. Such a contrast greatly enhances the impact of this novel on the reader and requires further study.
Etymological Analysis Model of the Chinese Hieroglyph: an Experiment
Authors: Terekhova N. V.
Published: May 2019

The paper presents a gradual model of etymological analysis of the Chinese hieroglyph. The research was based on the game approach logic expressed in the combination of Russian and Chinese linguistic analysis of Chinese characters. The established rules include verification of the graphic paradigm according to the stages of Chinese writing development. In addition, the rules involve grammatological, structural, semantic, and ideosemantic analyses. Individual research strategy included selection of linguistic, historical, and cultural sources for verification of the graphic-semantic characteristics of the Chinese character. The author applied a combination and sequence of research approaches and introduced an authentic analysis terminology. The authentic terminology was supported by analogies from Russian linguistics, as well as by the experience of etymologization of the character in Chinese philological science. The paper features a model of etymological analysis of the Chinese character. It consists of several stages/types of etymological reconstructions: formal-graphic,grammatical or structural, and semantic (including ideosemantic).The created etymological model was tested on the example of  etymologization of the Chinese hieroglyph "cart" 車 che / ju. Its paradigm was verified according to its graphic variants, which belonged to the early stages of ancient Chinese writing, namely jinwen, jiaguwen, and zhuanti. The author determined the graphic-semantic core of the character. Its graphic sensemaking form was systematically analyzed on the basis of verification of its graphic and semantic characteristics. Finally, the author conducted a semantic and ideosemantic analysis of the character, which included historical and archeological data on Chinese material culture. As a result, the study helped to define the etymological meaning of the character.
Stereotyped Perception of Animals in the Dutch Language: the Results of a Linguistic Experiment
Authors: Tereshko E. V.
Published: May 2019

The article describes the results of an associative experiment conducted in 2017, which involved 235 respondents. The author identified stereotyped characteristics of animals in Dutch. On the one hand, the characteristics manifest themselves in free associations with the zoonym. On the other hand, they can be obtained from sustainable comparisons, e. g. "as stupid as a donkey". These comparisons are seen as a sort of phraseological constructions. The experiment had two parts. In the "free associations" part, the respondents had to give a spontaneous reaction on a zoonym as stimulus, while in the "phraseological" part they had to add a missing adjective in a sustainable comparison. The author also intended to reveal the connections between the stereotyped perception of animals reflected in free associations and phraseology. The phraseological part of the experiment resulted in a larger amount of answers than expected. A comparative analysis showed that the stereotyped perception coincided in phraseology and free associations. In addition, the stereotyped perception changes with time and can produce new phraseological units.
Analysis of Neurocognitive Development of Moderate and Late Preterm Children in Early Childhood Using Bayley-III
Authors: Bakushkina N. I. , Rogacheva T. V.
Published: May 2019

The article features an empirical study of the development of neurocognitive functions in moderate and late preterm children at the age of 3, 5, 10, 14, and 25 months. To date, this population of infants is 75–80 % of the total number of premature infants, but specialists of different profiles do not give enough attention to this group of children, which limits the amount of information regarding their neurocognitive development, in spite of the fact that prematurity at any gestation period gives the right to refer the child to a risk group of different impairments. Premature birth has a certain impact on the development of the infant’s brain, affecting the important processes of differentiation of neurons, myelination, synaptogenesis, etc. Neurocognitive functions were measured by the Bayley Scales behavioral technique, third edition (Bayley-III). The technique makes it possible to assess the cognitive development, the development of receptive and expressive communication, as well as fine and gross motor skills. The research demonstrated that moderate and late prematurity has a selective effect on the development of neurocognitive functions, and the degree of impact depends on the stage of ontogenesis and the sphere of development.

Published: May 2019

Objective: The aim of this study was to evaluate the obstetrical outcomes in patients with triplet pregnancy, with and without antenatal care. Study Design: Case Series. Place and Duration of Study: The study was conducted at the Department of Obstetrics and Gynaecology, Services Hospital Lahore, from 1st January 1998 to 31st December 2003. Patients and Methods: Twelve women, including 6 booked and 6 unbooked patients, with triplet pregnancies of ?24 weeks of gestation, who presented at the Department of Obstetrics and Gynaecology, during the study period, were selected. Obstetrical history, examination and antenatal records were assessed. Obstetrical outcomes including length of fetal gestational ages at delivery, birth weights, apgar scores and neonatal assessment, admission in neonatal intensive care and stillbirths / neonatal deaths were recorded. Data was tabulated and comparison of obstetrical outcomes between booked and unbooked patients was done. Results:. In analyses that were limited to triplet pregnancies presenting of >=24 weeks of gestation thus excluding those which could have ended in miscarriage. There were 6 unbooked patients who came to Labour ward with preterm labour, premature rupture of membranes or preeclampsia and were delivered in the Department. 6 patients with triplet pregnancy were booked in the first trimester and received antenatal care. The data was retrospectively collected over 6 years period. There were 6 nullipara and 6 multipara women in our study. The average maternal age was 30.3 years (range 24-36 years) and average maternal weight was 63.25 Kg (range 53 - 75 kg). 10 patients had conceived by ovulation induction and 2 patients had conceived spontaneously. The average gestational age at delivery in unbooked patients was 32 weeks (range 29-35 weeks) and was 34.8 weeks (range 33 - 37 weeks) in booked patients. Caesarean section was the preferred mode of delivery. However, two unbooked patients presented in active labour at 29 and 30 weeks delivered vaginally. Among the booked patients 15 babies were live-born with apgar score `, two babies required admission in neonatal nursery and were discharged on recovery, however one baby died of sepsis in nursery after 4 days and there were no intrauterine deaths. Among the unbooked patients only 3 babies were live-born with apgar score >=7, five babies were admitted in neonatal nursery and recovered within a week. 7 babies died in the first week of life, mostly due to complications of prematurity. There were three intrauterine fetal deaths among the unbooked patients. Conclusion: It was concluded from the study that with antenatal management the obstetrical outcomes of triplet pregnancy improves.

Published: May 2019

El río Magdalena es una de las cuencas más importantes de Colombia, cuenta con gran cantidad de especies de peces importantes para la economía de muchas comunidades en el país. Sin embargo, una reducción marcada en las poblaciones de distintas especies asociadas se ha presentado por diferentes factores. Dentro de estos, se destaca la construcción de la represa de Betania, como respuesta a los requerimientos energéticos en Colombia. No obstante, especies migratorias como Prochilodus magdalenae, de importancia económica para la pesquería artesanal, se han visto seriamente afectadas, por lo que se ha generado la necesidad de analizar su estructura y diversidad genética, teniendo en cuenta la construcción de la represa como posible factor de fragmentación. Para esto, se hace adecuado el uso de microsatélites como marcador molecular en diferentes localidades de estudio aguas arriba y abajo de la represa. Esto permitió evaluar en 171 individuos el estado de la diversidad genética, cómo se encuentra distribuida esta variabilidad en las localidades de estudio y cómo influyen algunos factores como la construcción de la represa sobre su estructura genética. En este sentido, se obtuvieron 111 alelos distribuidos en siete loci 100 % polimórficos. Los promedios generales para la heterocigosidad observada fueron de 0,2169, mientras que para las esperadas fueron de 0,8316. Los estadísticos de Fst y PhiPT mostraron que existe una moderada diferenciación entre la represa de Betania y todas las localidades muestreadas. El análisis de inferencia bayesiana detectó la coexistencia de tres poblaciones en la cuenca del río, entre las que destaca la de Betania. Estos resultados se pueden estar presentando, debido a la fragmentación que genera la represa en el río, impidiendo el flujo genético entre las localidades aguas arriba y aguas abajo de la represa

El objetivo de este trabajo fue estudiar la estructura del ensamblaje de macroinvertebrados bentónicos de la laguna del Parque Unzué y discutir sobre su calidad de agua. El área de estudio se encuentra en la ciudad de Gualeguaychú (Entre Ríos, Argentina), sobre la margen izquierda del río homónimo. La laguna tiene un área de 2750 m2 y una profundidad máxima de 1,70 m. Durante 2016-2017, se muestreó en 3 puntos (n=10), se midieron parámetros in situ y se recolectaron muestras de bentos, se caracterizaron los sedimentos y los macroinvertebrados fueron identificados hasta el menor nivel taxonómico posible y se los agrupó en grupos funcionales alimenticios (GFA). Se calculó la diversidad, la diversidad máxima esperada (Hmax) y los números de Hill. No se hallaron diferencias estadísticamente significativas (p<0,05) entre los puntos de muestreo y los parámetros in situ; sin embargo, respecto a los macroinvertebrados, los puntos 1 y 3 presentaron mayor similitud que estos con el punto 2, posiblemente debido a las diferencias en el sustrato. Se colectaron 1726 individuos distribuidos en 13 taxones:  Oligochaeta (1), Hirudinea (1), Bivalvia (4), Gastropoda (3), Amphipoda (1) e Insecta (3), los cuales son característicos de ambientes con abundante materia orgánica. La diversidad fue baja y coincidió con la Hmáx solo en el 23 % de los casos, el número de especies efectivas varió de 1-5 y los taxones dominantes representaron el 40 % de la riqueza. Respecto a los GFA, la abundancia se distribuyó en: colector-recolector, colector-filtrador y depredador y, la biomasa, en raspador y colector-filtrador. La laguna del Parque Unzué evidenció efectos de contaminación orgánica durante todo el período de muestreo reflejado en la estructura y composición del ensamblaje de macroinvertebrados.

A strong lateral inhomogeneity by saturation was created during the experiments. The electrical response is sensitive to the addition of all types of fluid in the rock samples. At the same time, the reaction to the addition of highly concentrated salt solution in the samples is weak, while the reaction to the addition of weak concentrated salt solution and kerosene is strong. A high correlation is observed between the shape of the electrical response spectra of dry and damped cores, up to 0.9. For kerosene, the shape of the spectrum varies greatly, the rank correlation coefficient of the shape of the spectra is 0.3. The fact of a significant increase in electrical response on addition of non-polar fluid (kerosene) to the core is beyond the theoretical framework and may be associated with the creation of strong lateral petrophysical heterogeneity by saturation. The strong sensitivity of the amplitude of the electroseismic response of rocks to very weak but non-homogeneous saturation is interesting for the development of remote methods for determination of the type of fluid saturation of rocks, when searching for minerals and for the development of the methods for prediction of geophysical catastrophes.

En el artículo se realiza una sistematización de la propuesta de Fredric Jamesonde “estética del trazado de mapas cognitivos”, pensada desde el arte y con finespedagógicos. Se plantea el objetivo de profundizar en la reflexión teórica sobrelas posibilidades desarrolladoras de una arte-educación basada en la estéticade mapas cognitivos, un tipo de pedagogía a través del arte que contribuya a laformación de cultura política en la condición histórica de la posmodernidad. Seconcluye, a través de un ejemplo, que el arte contemporáneo, al producir mapasestéticos y conceptuales de diversas problemáticas de actualidad, y por el tipode comunicación/comprensión que exige del receptor, puede ser un reveladorpunto de partida para la formación de un sujeto capaz de reescrituras críticasdel propio devenir existencial, lo cual implica una concientización del lugar quese ocupa en la realidad social.

Background

Many university students are lacking adequate physical exercise and are failing to develop physical activity (PA) behaviors in China. PA app use could improve this situation.

Objective

The aim of this study was to use the unified theory of acceptance and use of technology (UTAUT) to investigate the intention to use PA apps among university students in Guangzhou, China, and how body mass index (BMI) moderates the effects of UTAUT in explaining PA app use intention.

Methods

A cross-sectional study was conducted among 1704 university students from different universities in Guangzhou, China. The UTAUT model was used to measure the determinants of intention to use PA apps.

Results

Of the participants, 41.8% (611/1461) intended to use PA apps. All three UTAUT-related scales (performance expectancy, effort expectancy, and social influence) were positively associated with the intention to use PA apps after adjusting for background variables (adjusted odds ratio 1.10-1.31, P<.001). The performance expectancy scale had stronger associations with the intention to use PA apps among those whose BMI were beyond normal range compared with those whose BMI were within normal range (P<.001).

Conclusions

UTAUT is useful for understanding university students’ intention to use PA apps. Potential moderating effects should be kept in mind when designing UTAUT-based interventions to improve PA via app use.

Monitoring strategy of antiretroviral pre-exposure prophylaxis adherence among serodiscordant couple  Antiretroviral pre-exposure prophylaxis (PrEP) has been recommended as HIV prevention but poor medical adherence can cause suboptimal therapy. This study explored the strategies of monitoring PrEP adherence among the serodiscordant couples. This systematic review based on 4 data bases (Scopus, Pubmed, Ebsco and Sage Journal), included clinical trial studies articles between 2013-2018, in English, and available in full-text. Papers, which not met the inclusion criteria, will be excluded. Keywords used in this study are ‘serodiscordant couple’ AND ‘method’ OR ‘strategy’ OR ‘approach’ AND ‘pre-exposure prophylaxis intention’ OR ‘pre-exposure prophylaxis adherence’. This study discovered various strategies applied based on the type of delivering process, the variance of dose, and variance of preference of the couple. Preference of PrEP dose and type of application related to heterosexual or homosexual orientation and their social commitment. The paper explains the advantage of M-health and biomarker level monitoring.

Success rate in handling incomplete abortion in EmOC primary health care in West SumbawaPurposeThis study explored the success of incomplete abortion in EmOC PHC in West Sumbawa.MethodThis research used descriptive analytic design with mix method approach. Quantitative research with cross sectional design and qualitative research with multiple-case study approach. The quantitative research sample is mother with incomplete abortion and qualitative research sample that is midwife, doctor and head of Puskesmas. Quantitative data analysis used chi-square test and logistic regression. Qualitative data collection using indepth interview method.ResultsHandling of successful incomplete abortus was 63,3% and most of EmOC PHC was complete 67,3%. There is a significant correlation between the success of incomplete abortion handling with the completeness of EmOC PHC. The likelihood of successful completion of incomplete abortion cases in complete EmOC PHC was 4.1 times greater than that of incomplete EmOC PHC. There was a significant relationship between maternal gestational age at abortion with successful incomplete abortion treatment (OR = 7,1; CI95% 1.27-40,2). Qualitative results show that EmOC teamwork can influence the success of handling incomplete abortion cases.ConclusionCompleteness of EmOC PHC has relationship with handling of incomplete abortus case.

Out-of-pocket household expenditure for child health prevention services: two-part and tobit modelPurposeTo find out socio-economic determinants and the amount of out-of-pocket (OOP) for household expenditure in health prevention for children.MethodsThis study compared two approaches from several alternative assumptions including the two-part model and Tobit, which can be used when variable analysis has a problem selection. The dependent variable was household expenditure for children health prevention services in Indonesia, where the probability of dependent variable was affected by latent variables.ResultsThe two-part model and Tobit estimate that rural areas in NTT province can reduce out-of-pocket preventive health expenditures for children three times lower than the rural provinces of Papua. The higher the education of the head of the household, the greater of the possibility of preventive out-of-pocket child health is. Distribution of poverty rates based on quintiles provides a regressive picture of the poorest households based on expenditure per capita.  ConclusionThis study is expected to be a comprehensive policy recommendation to suppress out-of-pocket preventive health expenditures for children. Thus, the distribution of health services is a priority for vulnerable groups (children) and the poor.

Abstract. This study aimed to examine the effects of anchoring in task performance appraisal. It was hypothesized that there would be difference score inmeasuring task performance with high anchoring and low anchoring methods. High anchoring methodwas predicted to show higher scores rather than using low anchoring method. Participantswere 117 post-graduate students from Master of Management in Universitas Gadjah Mada. They were assigned in two groups. The first group (N=70) was instructed to rate an employee from lower to higher score (high anchoring method), while the second group (N=47) was instructed to rate the employee fromhigher to lower score (low anchoring method). Result of independent sample T-test showed that anchoring method had no significant effect on task performance appraisal. Factors which might be affecting this result are discussed Keywords: anchoring; appraisal; performance; post-graduate students; quasi-experimental study; task performance;

The diffusive gradient in thin film (DGT) is an analytical technique to determine phosphate in the environment. This technique uses a thin film diffusive hydrogel in contact with a binding phase (ferrihydrite) to binding of phosphate. The released phosphate from marine sediment of Jakarta Bay was studied by DGT technique for effect of salinity and oxygen condition. Effect of salinity was observed by NaCl concentration from 0-35 g/L. The maximum phosphate release from sediment was occurred at the concentration of NaCl 30 g/L with incubation for 15 days with phosphate released at 113.99 μg/L, MDGT of 4.7723 μg and CDGT of 17.56 μg/L. The experiment showed the increase of MgCl2 and CaCl2 concentration reduced phosphate release from sediment. The condition of oxygen indicating the release of phosphate under anaerobic conditions is greater than the aerobic condition. The aerobic conditions with incubation for 21 days showed the release of phosphate from sediment to overlying water of 124.72 μg/L, MDGT of 2.4492 μg and CDGT of 6.4380 μg/L. Anaerobic conditions with incubation for 21 days showed phosphate release from sediment to overlying water of 208.62 μg/L, MDGT of 6.1081 μg and CDGT of 16.06 μg/L. The experiment shows that salinity and oxygen concentration influences phosphate release from marine sediment of Jakarta Bay.
