Language Politeness of Preschool Children in the Market Environment
Authors: Fauziah M Sitti , Trisnawati Ira , Aminuddin Aminuddin
Published: April 2022

Politeness is an important aspect of language because it can help people communicate more quickly. Children learn politeness through their social environment from an early age. Children are taught how to greet people politely, express their desires in an ethical manner, express curiosity, and express disagreement without screaming or using high voices, among other things. This study involved phenomenological qualitative research, which examined the natural phenomena of language. Data were collected by listening to the use of language without participating in the discussion process and using other free listening techniques. The purpose of the note technique that was used was to observe linguistic phenomena as they occurred. Students in classes B1 and B2 at Raudhatul Athfal (RA) Ash-Syafi’iyah T / A 2018/2019 in Kendari were the data sources. According to the findings, children’s language politeness in the family environment was heavily influenced by the situation and circumstances of the environment. Children who had grown up in a market environment had different communication language. Students at RA Ash-Syafi’iah learned about language in the sense of using it to communicate with other people or animals. Children used greetings, permission, thanks, and prohibitions as examples of imperative speech as a sign of politeness. Furthermore, the politeness of language in the children from the market environment had an effect on the intonation of the child’s voice when speaking, as well as the child’s kinesthetic signals.

Published: April 2022

This study’s focus was children as the subjects of sexual assault by blood relatives, commonly known as incest, in Kendari city. The main questions were: 1) what were the modus operandi of these blood relatives in committing the sexual assault; 2) what were the physical and psychological impacts inflicted on the victims; and 3) what were the treatments given by the authorities in an attempt to rehabilitate the victims from post-accident trauma? The data were collected through interviews, observations and document analysis. The findings indicated that these blood relatives committed the sexual assault based on the following modus operandi: isolating the victim from the neighbourhood, taking the victim on a trip, threatening the victim with killing or beating, teasing the victim by offering something desirable, or poisoning the victim with drugs. The physical impacts inflicted on the victims were vaginal infections with pus and blood streaming from the lesion, dysfunctions of the reproductive organs, high-risk pregnancy, lacking in vitality, and paleness. Regarding the psychological impacts, the victims suffered from post-accident trauma by living in a constant fear and avoiding contact with people, isolating themselves from the crowd, social damnation and excommunication that led to internal disharmony in the family or parental divorce. The authorities, led by The Woman Empowerment and Children Protection Service, attempted immediate rehabilitation of the victims by working in cooperation with third parties such as civil society organizations and psychologists to provide basic needs, counsel the neighbourhood where the victims live to support and foster the rehabilitation, as well as educate them that such a tragedy should not justify social damnation upon the victims and their families.

Published: April 2022

Historical and cultural tourism have many benefits, not only for the preservation of objects but also for the tourists as connoisseurs. As the country with the largest Muslim population in the world, Indonesia has many mosques as places of worship for Muslim people. There are also many mosques that have historical and cultural values. Several mosques in Indonesia are used as religious tourism sites, but their activities are limited to pilgrimages. However, in Malaysia and Singapore, mosques are also used as part of historical and cultural tour packages for anyone, to demonstrate cultural diversity, cultural understanding, tolerance between religions, Islamic history, and the history of mosques and the surrounding Muslim community. This study aimed to examine how the two neighboring countries in Southeast Asia make mosques a hybrid space as a place of worship as well as a tourism location. This research used a case study approach, focusing on two mosques, namely the Sultan Abu Bakar Mosque in Johor, Malaysia and the Jamae Mosque in Chulia, Singapore. The results of this study can be used by planners, designers and managers to develop mosques as part of a historical and cultural tourism landscape in Indonesia.

Published: April 2022

Objectives: To compare maternal and neonatal outcomes concerning emergency or planned cesarean deliveries in pregnancies complicated by placenta previa (PP), and to evaluate factors related to blood transfusion requirement.
Methods: Three hundred sixty-three women with PP with (n = 80) and without (n = 283) placenta accreta spectrum (PAS) who delivered between May 2016 and May 2021 were retrospectively reviewed. The patients were allocated to two main groups as PAS and non-PAS and into two subgroups as emergency cesarean delivery (ECD) and planned cesarean delivery (PCD).
Results: One hundred twenty-eight deliveries were emergency and 155 were planned in non-PAS group. In PAS group 38 patients were delivered urgently and 42 were delivered as planned. General anesthesia was preferred more frequently in emergency cases. Gestational age, birth weight, and the 1st and 5th minute APGAR scores of the infants were significantly lower and neonatal intensive care unit (ICU) admission was significantly higher in the ECD cases (p < 0.001) in both PAS and non-PAS groups. The total amount of blood and blood product transfused (p = 0.005), length of hospital stay (p = 0.022) were higher in the ECD cases and adult ICU admission was significantly higher in the ECD cases in non-PAS group (p = 0.016). In multilinear regression analysis, the need for blood transfusion was found to increase with the number of previous cesarean sections, ECD, PP with PAS, general anesthesia, and uterine artery ligation.
Conclusions: In placenta previa, which is an obstetric condition associated with serious maternal and neonatal morbidity and mortality, adverse maternal and neonatal outcomes increase in cases of emergency cesarean delivery.
Influence of the location of contact spots on thermal contact conductance
Authors: Murashov M.V. , Golubtsova E.S.
Published: April 2022

Among the currently widespread fractal and stochastic models of thermal contacts, the location of contact spots formed from the interaction of roughness protrusions is not tracked in any way. Based on the results of the numerical solution of three model two-dimensional problems of thermal contact using simulation in the ANSYS finite element analysis software system, a significant effect of the location of these spots in the nominal contact area on thermal contact conductance was determined. It is shown that thermal contact conductance is not proportional to the number of actual contacts or the fraction of the actual contact area in the nominal area. As a result of the work, conclusions were drawn that even small spots of actual contact significantly change the thermal contact conductivity. Of the existing contact models, this phenomenon can be taken into account by deterministic models, since stochastic and fractal ones do not track the location of spots.
On the warheads of anti-aircraft guided missiles of the S-25 anti-aircraft missile system. Part 2
Authors: Metelsky A.O. , Markov V.A. , Pusev V.I.
Published: April 2022

The part 2 of the paper introduces the results of studying the designs of warheads of anti-aircraft guided missiles. Warheads of V-300 anti-aircraft guided missiles of the S-25 anti-aircraft missile system were taken as an example. The analysis of information from open sources allowed us to restore the design and layout diagrams of the warheads of the later stages of modernization of the S-25 anti-aircraft missile system and assess their combat characteristics. Other devices that make up the combat equipment, i.e. a combination of a warhead and an explosive device, of an anti-aircraft guided missile are also considered: safety-and-arming mechanisms and radio fuses. As in the first part, we implemented a systematic approach to studying and designing warheads of anti-aircraft guided missiles, so carriers, i.e. anti-aircraft guided missiles, were also taken into account. Nuclear or special warheads, which equipped missiles of V-300 anti-aircraft guided missiles of the S-25 anti-aircraft missile system after various stages of modernization, are also considered.
Aspects of applying combined mass–time functional in solving the problem of optimizing the multiple-burn transfer of a spacecraft into a high-energy orbit
Authors: Kiriliuk E.V. , Stepanov M.N.
Published: April 2022

Through the example of a non-coplanar transfer of an orbital unit with a low reference to a geostationary orbit, the paper describes the main aspects of applying the combined mass–time functional to the problem of optimizing multiple-burn transfer using the maximum principle. The study analyzes the saturation of the dependence of the orbital unit’s mass in the target orbit on the weight coefficient for a wide range of the orbital unit’s mass-energy characteristics of upper stages for a given structure of the optimal trajectory. Furthermore, a similar analysis was carried out for structures of optimal trajectories containing a different number of perigee active sections, with fixed mass-energy characteristics of the upper stage. The ranges of variation of the weight coefficient are demonstrated, in which there are optimal schemes containing a different number of perigee active sites. Recommendations are given for setting the saturation coefficient, at which the solution of the problem with the combined functional can be considered coinciding with the solution of the problem of maximizing the finite mass of the orbital block.

“Turning Points” For Aging Genealogists: Claiming Identities And Histories In Time
Authors: Hackstaff Karla B.
Published: April 2022

Based on qualitative in-depth interviews, I examine the use of genealogy with regard to the current historical moment for identities rooted in kin, race, class, gender, nation—and age. Drawing on the concept of “turning points” coined by Anselm Strauss, I explore moments that motivate the doing of family genealogy. First, I suggest that Strauss’s turning points may occur simultaneously and converge like vectors across time. Second, I argue that late middle-age lends itself to “identity extensions”, which I define as a reevaluation of self that acknowledges one or more of the following: the significance of extended kin to one’s identity; reverence for ancestors; a social responsibility to the future. Finally, I analyze how the current era informs a particular generation’s genealogical endeavors. I conceive of U.S. baby boomers’ genealogical projects as an expression of longing for connections in family lives and for a place in social history across the generations.
Cynicism in the Indian I.T. Organizations: An Exploration of the Employees` Perspectives
Authors: Dhar Rajib Lochan
Published: April 2022

Cynicism is described as a mind-set characterized by hopelessness, disappointment, and disillusionment, and is also associated with scorn, disgust, and suspicion. This strong negative attitude has infiltrated Indian I.T organizations, and is believed to be responsible for unfavorable organizational consequences, even though, hardly any studies have explored the causes and concerns of employee cynicism about their organizations in the Indian context. The present research centers around two qualitative case studies through in-depth interviews with seventy two participants undertaken in western India to investigate the causes and concerns of employee cynicism towards employer organization. Findings of the study indicate that workplace perceptions significantly influence organizational cynicism, which is largely influenced by poor leadership, organizational politics, decisive culture, accessibility of benefits and un-met expectations. As these findings have important organizational implications, I recommend for further studies on cynicism in the future.

Актуальность исследования обусловлена необходимостью разработки новых методик по утилизации металлических отходов. Данное направление, при участии различных интенсифицирующих воздействий, относится к ресурсосберегающим, технологическим, минимизирующим объемы капитальных затрат на сырьё, производство и последующую реализацию. Цель: изучить физико-химические закономерности процесса щелочной переработки алюминиевых отходов в поле ультразвука, предложить механизм этого процесса и на основании установленных закономерностей и предложенного механизма разработать методику щелочной переработки алюминиевых отходов. Объекты: образцы алюминиевых отходов в виде пластинок и стружки. Методы: волюмометрия, дифференциально термический анализ, оценка и анализ кинетических кривых процесса при разных температурах. Результаты. Проведен анализ кинетических кривых, рассчитаны константы скоростей процесса при различных температурах, найден порядок химической реакции. По рассчитанной энергии активации процесса была дана характеристика о кинетической области процесса. Найдено массовое содержание алюминия в образцах. Согласно полученным данным, воздействие на систему ультразвуком способствовало увеличению скорости химического процесса на 44,1 % при 303 К; на 25,4 % при 313 К. Сам процесс начинался в течение 1…3 секунд и завершался в течение нескольких минут, что подтверждает возможность утилизации алюминиевых отходов с помощью щелочных растворов при невысоких температурах. Полученный водород можно использовать в водородной энергетике, поскольку он является единственным газообразным продуктом реакции, что снимает необходимость в его очистке перед транспортировкой. Отфильтрованный гидроксид алюминия можно использовать в силикатной промышленности для получения пористой корундовой керамики.
Measuring Moral Panic Propagation on the Interpersonal Level: Case of Pro-ana Women Bloggers
Authors: Mikhaylova Oxana
Published: April 2022

Несмотря на большое количество работ, посвященных изучению моральных паник, практически отсутствуют исследования, касающиеся анализа эффекта социального окружения в их распространении. Эта статья вносит вклад в решение данной проблемы, предлагая методологический подход, который может быть использован при изучении распространения моральных паник в ходе межиндивидуальной коммуникации. Основанный на сочетании анализа эго-сетей и биографических интервью, этот подход позволяет показать как индивидуальные взаимодействия с членами социального окружения могут воздействовать на вовлеченность человека в моральную панику. Возможности этой методологии демонстрируются на примере моральной паники относительно ожирения. Женщины про-ана блогеры рассматриваются как моральные паникеры, которые создают моральную панику вокруг избавления от «лишнего» веса. Анализ проводится на основе 50 биографических интервью и публичных онлайн дневников русскоязычных женщин, которые причисляют себя к про-ана культуре и ведут о ней блоги в социальной сети «ВКонтакте». Результаты обсуждаются в связи с исследованиями моральной паники относительно ожирения, а также литературой, посвященной изучению распространения моральных паник.

Published: April 2022

Practical activities are a series of activities carried out to apply skills or practice something that requires practical tools in its implementation. The purpose of using practical tools is to meet the needs of practitioners in carrying out a process. One of the physics concepts that can be explained through practical activities is calorimetry. Specific heat is one of the observations made during the practicum using a calorimeter. The specific heat of the material is usually measured using a coffee-cup calorimeter manually. The obstacle faced by the practitioner during the calorimetry practicum is that the measurement of the dependent variables takes up the time and attention of the practitioner in the implementation of the practicum. The objectives of this research are (1) to design an Arduino Uno-based calorimeter practicum tool; (2) explain the work system of the Arduino Uno-based calorimeter practicum tool; (3) measuring the amount of heat on the Arduino Uno-based calorimeter practicum tool; (4) comparing the effectiveness of the Arduino Uno-based calorimeter practicum tool with the coffee-cup calorimeter practicum tool. This study uses a type of research and development (Research and Development) with a Nieveen design conducted in the Laboratory of Physics Education Study FKIP Jember University. Nieveen's design research procedures include Preliminary Research, Prototyping Stage, and Assessment Stage (summative evaluation). Based on the results of data analysis, there is a very strong relationship between the data from the measurement results of the design of the tool and the data from the results of the measuring instruments that have been standardized. The results of the measurement of the specific heat of the material using the design of the tool indicate a conformity with the previous theoretical study.

Uncovering social workers’ knowledge use
Authors: Wallander Lisa
Published: April 2022

The aim of this study was to explore whether social workers can become more explicit about their knowledge use if they are assisted in analyzing the rationales underlying their conclusions about diagnosis and treatment. By dissecting the rationales provided by 46 Swedish social work practitioners and students in response to two case vignettes describing vulnerable children and their families, and by systematically comparing the rationales generated by two methods of data collection, the study arrived at mixed results. At the general level, the analyses showed that the social workers were indeed more explicit about their knowledge use when assisted in analyzing their rationales. However, there was substantial variation across different types of argument components. While a majority of the respondents spontaneously provided basic level arguments, prompts were often required for them to make explicit the level of uncertainty associated with a conclusion, and to elicit information about specific knowledge sources. Further, most social workers failed to provide a more general explanation for why they inferred a specific conclusion from the data, even when queried. Finally, the results indicated that the knowledge underlying conclusions about treatment was more prevalent and/or explicit in social workers’ reasoning than the knowledge used for arriving at conclusions about diagnosis.

Tanzania is working towards agricultural modernization aiming and improving agricultural productivity. The aim has been to transform traditional agricultural practices with modern practices and help smallholder farmers improve their productivity. However, there has been mixed evidence on the success of such modernization efforts some showing success and others showing the failure. By using available literature, this paper aim at showing the position of smallholder farmers in agricultural modernization process. Findings shows that, agricultural modernization has left smallholder farmers under a marginalized position filled with land grabbing, problems on availability, accessibility, affordability and the quality of agricultural inputs together with the problem of market for agricultural products. As a deliberate effort to improve agriculture sector the government need to increase investment in agricultural inputs by facilitating the availability of industries which produce agricultural inputs like fertilizer. Also, the government should encourage farmers to join into cooperative unions or groups to help them have bargaining power when it comes to marketing their crops.

Matematika merupakan salah satu mata pelajaran yang memegang kontribusi sangat penting dalam pendidikan. Akan tetapi, pendapat sebagian siswa mata pelajaran matematika masih dianggap mata pelajaran yang sulit. Seiring berjalannya waktu, pembelajaran matematika perlu memenuhi tuntutan abad 21 dan ditunjang dengan keterampilan berpokok Higher Order Thinking Skills (HOTS). Salah satu solusi untuk memecahkan hal tersebut adalah dengan mengembangkan perangkat pembelajaran berpokok HOTS berupa modul pembelajaran berpokok HOTS. Tujuan dari penelitian ini yaitu untuk membuat modul sistem persamaan linier dua variabel (SPLDV) berpokok Keterampilan Berpikir Tingkat Lanjut (HOTS) untuk pembelajaran matematika tingkat SMP yang valid. Metode yang digunakan dalam penelitian ini adalah metode Research and Development (R&D) dengan menggunakan model pengembangan 4D dengan tiga tahapan yaitu definisi, desain, dan pengembangan. Pada tahap pengembangan, tiga ahli melakukan uji validasi sebagai validator. Di sini, dua guru berpengalaman STKIP PGRI Banjarmasin dan satu guru berpengalaman SMP Negeri 14 Banjarmasin. Berdasarkan hasil uji validasi lembar validasi, nilai rata-rata (Va) untuk semua aspek evaluasi adalah 3,32, sehingga modul sistem persamaan sistem linear dua variabel berpokok kemampuan berpikir tingkat tinggi (HOTS) untuk matematika menengah pertama termasuk dalam kategori yang valid.

Background: Transarterial chemoembolization (TACE) is the standard treatment for BCLC-B hepatocellular carcinoma (HCC). The glass membrane emulsification device (GMD), a novel device, produces a high percentage of water/oil emulsions with homogeneous and stable droplets. There are few reports on the efficacy of GMD-conventional-TACE (GMD-c-TACE). We aimed to evaluate the efficacy of GMD-c-TACE. Methods: Seventy-one patients with HCC of tumor diameter <5 cm who underwent c-TACE with and without GMD were included in this study to investigate local recurrence and hepatic functional reserve. Results: Local recurrence rates without GMD-TACE was 3.0% at 6 months, 16.7% at 12 months, 35.0% at 18 months, and it then plateaued. Hence, the local recurrence rate in the GMD-c-TACE group was 7.7% at 14 months and 23.1% at 20 months, respectively. GMD-c-TACE had a significantly lower local recurrence. Multivariate analysis showed that GMD-c-TACE could suppress local recurrence and maintain the hepatic reserve. Conclusions: GMD-c-TACE allows dense accumulation of lipiodol in the tumor and attainment of good local control. Additionally, the inhibition of the release of anticancer drugs may maintain the hepatic reserve. GMD-c-TACE is useful in preventing local recurrence and is expected to become the standard treatment form of c-TACE in the future.

Tri-dimensional (3D) cell aggregates or spheroids are considered to be closer to physiological conditions than traditional 2D cell culture. Mesenchymal stem cells (MSCs) assembling in spheroids have increased the survival of transplanted cells. The regulation of the biological processes that maintain crucial physiological reactions of MSCs is closely related to the functioning of ion channels. The pattern of expression, role and regulatory mechanisms of ion channels could be significantly different in 3D compared to 2D culture, and, thus, needed to be properly analyzed on the level of ionic currents. We developed a specific approach that allowed us to register, for the first time, endogenous ion channels in endometrial MSCs (eMSCs) assembled in spheroids. Particularly, using the single-channel patch-clamp technique, we have recorded the activity of ion channels and observed their functional interplay in mechanosensitive clusters. Our experimental protocol could be applied for identification and studying of ion channels in 3D cell cultures.
