Published: June 2022

Hormon AIA berperan besar dalam memperbesar dan memperpanjang sel, pembelahan sel, khususnya pada daerah ujung tanaman. Bakteri yang memiliki kemampuan dalam menghasilkan hormon AIA diantaranya Enterobacter sp., Azospirillum sp., Klebsiella sp., Alcaligenes faecalis, Azoarcus sp., Serratia sp., Azotobacter sp., Cyanobacteria, Erwinia herbicola, Pseudomonas sp., Rhizobium, Bradyrhizobium, Agrobacterium tumafaciens. Sintesis AIA ini memerlukan senyawa tambahan berupa triptopan. Namun beberapa bakteri mampu memproduksi AIA tanpa penambahan prekursor. Penelitian ini bertujuan untuk memperoleh isolat bakteri penghasil hormon AIA dari tanah Kebun Raya Liwa. Pada ini diawali dengan isolasi bakteri tanah asal Kebun Raya Liwa, selanjutnya dilakukan uji kemampuan produksi AIA secara kuantitatif tanpa penambahan triptopan. Pengujian produksi AIA secara kualitatif dilakukan dengan menggunakan media Nutrien Broth dengan metode spektrofotometri dengan penambahan reagen salkowsky dan dilakukan pengamatan setelah 72 jam inkubasi. Data yang didapatkan disajikan dalam bentuk tabel. Hasil penelitian didapatkan 9 isolat yang mampu menghasilkan hormon AIA dengan kadar yang berbeda. Isolat penghasil AIA tertinggi yaitu isolat DT1 dengan kadar 114 ppm yang mempunyai karakteristik berbentuk bacil berwarna putih susu dan tidak berspora.

AIA hormone plays a role in enlarging and elongating cells, and cell division, especially at the tip of the plant. Bacteria that have the ability to produce IAA hormones include Enterobacter sp., Azospirillum sp., Klebsiella sp., Alcaligenes faecalis, Azoarcus sp., Serratia sp., Azotobacter sp., Cyanobacteria, Erwinia herbicola, Pseudomonas sp., Rhizobium, Bradyrhizobium, Agrobacterium tumafaciens. The synthesis of AIA requires an additional compound in the form of tryptophan. However, some bacteria can produce AIA without the addition of precursors. The goal of this study was to obtain isolates of AIA hormone-producing bacteria from the soil of the Liwa Botanical Gardens. This begins with the isolation of soil bacteria from the Liwa Botanical Gardens, then a quantitative test of AIA production capability is carried out without the addition of tryptophan. Qualitative testing of AIA production was carried out using Nutrien Broth media with spectrophotometric methods with the addition of Salkowsky reagent and observations were made after 72 hours of incubation. The data obtained are presented in tabular form. The results showed that 9 isolates were able to produce the AIA hormone at different levels. The highest AIA-producing isolate was the DT1 isolate with a concentration of 114 ppm which had the characteristics of a milky white bacillus and no spores.

Rangkong merupakan jenis burung pemakan buah (frugivory). Buah yang dikonsumsi rangkong dikategorikandalam buah yang kecil dengan jumlah yang banyakdan jenis buah yang memiliki batu (stone seeds), yaitu jenis fikus dan non fikus. Peran rangkong di hutan sangatlah penting yaitu sebagai penebar bijimelalui sisa makanan dan kotoran rangkong karena sistem pencernaannya yang tidak merusak biji sehingga mencerminkan hutan yang sehat dan menandakan masih adanya pohon-pohon besar di wilayah tersebut. Penelitian ini dilakukan di Stasiun Penelitian Way Canguk (SPWC) TNBBS Lampung dengan metode observasi langsung melalui pengamatan laju pertumbuhan biji pakan rangkong secara generatif (semai) pada lokasi yang berbeda. Data disajikandalam bentuk tabel dan diagram kemudian dianalisis secara deskriptif. Hasil penelitian menunjukan diperolehnya biji sebanyak 581 buah dari 12 famili dan 26 spesies serta 7 jenis yang belum teridentifikasi. Nasib biji setelah dimuntahkan tumbuh sebanyak 39% dari keseluruhan biji yang diperoleh dan 61% biji tidak mengalami pertumbuhan diduga karena adanya predator biji dan rusaknya biji serta faktor naungan yang dapat menghambat pertumbuhan biji. Biji dari buah fikus yang berasal dari defekasi tidak mengalami pertumbuhan. Nilai laju pertumbuhan semai di alam lebih cepat dibandingkan dengan semai yang berada di media terkontrol atau disekitar kamp SPWC.

The hornbill is a type of frugivory bird. The fruit consumed by the hornbill is categorized into small fruit with a large number and the type of fruit that has stone seeds, namely ficus and non-ficus types. The role of hornbill in the forest is very important, namely as seed dispersal through food waste and hornbill droppings because their digestive system does not damage the seeds so that it reflects a healthy forest and indicates the presence of large trees in the area. This research was conducted at the Way Canguk Research Station (SPWC) TNBBS Lampung with direct observation by observing the growth rate of generative hornbill feed seeds (seedlings) at different locations. The data is presented in the form of tables and diagrams and then analyzed descriptively. The results showed that 581 seeds were obtained from 12 families and 26 species and 7 species that had not been identified. The fate of seeds after vomiting grew as much as 39% of the total seeds obtained and 61% of seeds did not experience growth, presumably due to seed predators and seed damage and shading factors that could inhibit seed growth. Seeds of ficus fruit from defecation did not grow. The value of the growth rate of seedlings in nature was faster than those in controlled media or around the SPWC camp.

Bacteria have potencial as larvicide of Aedes aegypti. The purpose of this study is to determine the effect of Serratia marcescens strain MBC1 against larval third instars of Aedes aegypti. This research was an experimental study with two kinds of testing. The larvicide test to determine the mortality of the larval and the continuous test to observe the development of the larval after treatment with the larvacide. The third instars of mosquito larval were given bacterial extract in four concentrations (125, 250, 500, and 1000 ppm), and observed mortality during 72 hours. The continuous larvicide test was observed at two concentrations (500 and 1,000 ppm). The observation is completed when all of the larvae died. The positive control used Abate® 1% and the negative control used natural water. The treatment was repeated 4 times. The results show that LC50 and LC90 of S. marcescens extract are 66,426.02 dan 749,001.41 ppm. All of the larvae in the continuous test die after 18 days have been givenan extract of S. marcescens strain MBC1. The experiment shows that the larvicide of extract of S. marcescens influences the length of the life cycle and larvae of Ae. aegypti die before reaching the adult.

Abstract
Autoimmune adverse effects of immune checkpoint inhibitors (ICIs) are rare but may be life-threatening. We performed a retrospective analysis of the immune-related adverse effects (irAEs) of ICIs in the Masaryk Memorial Cancer Institute (MMCI) from 2011 to 2021. The ICIs were administered to 648 patients. Severe irAEs were pronounced in 83 patients (12.8 %). Further, we report a case of severe irAE after treatment with ipilimumab and nivolumab. Prednisone, mesalazine, octreotide, infliximab, vedolizumab, and mycophenolate mofetil were used to manage G4 colitis, with partial response. Early diagnosis and appropriate management of irAE are essential in the perspective of further oncological treatment.

Abstract
Currently, loosening and separating machines that combine the operations of crumbling and separating of soil according to the treated layer depth have come to the forefront. Interaction of the rotor blade of these machines with the soil comprises three stages: soil core formation; steady movement; and dumping of soil from the separating grid. The article determined the direction and magnitude of soil displacement, parameters and shape of the furrow formed after the ripper passage. Based on theoretical research, a mathematical model of the interaction of working bodies with the soil was developed. The initial data were obtained experimentally, and the model was justified. As a result, it was found that the supplied soil layer thickness and the fracture angle of ripper have the greatest influence on the transporting capacity of rotor ripper. Reducing the rotor blade entry angle into the soil from 45° to 30° made it possible to raise the second soil feed of the loosening and separating machine by more than 40 times. The width of rotor ripper practically does not affect the transporting capacity. Changing the angle of ripper entry into the soil allowed obtaining of the required transporting capacity of ripping and separating machine without changing the rotor design. Practical significance of the study lies in the possibility of increasing the work productivity without increasing its energy indicators.

Abstract

Research background: The economics of incarceration is having an increasing impact on the economies of the world due to the rapid growth in the number of prisoners in the world The search for effective solutions that can help reduce government spending on prisoners in penitentiaries and at the same time ensure the safety of society is becoming increasingly important. These studies used the method of binary logistic regression to predict the probability of convicted criminal recidivism in the future.

Purpose: The aim of the paper is to build an effective forecasting model that, based on the statistical and dynamic data of convicts, will provide information for optimal post-trial decisions, such as the grounds for possible parole, probation or length of sentence.

Research methodology: The data were collected on the basis of statistical data of 13,010 convicts serving sentences in penitentiary institutions in Ukraine. To predict the probability of convicts committing criminal offenses binary logistic regression and ROC-analysis (Receiver Operator Characteristic analysis) were used.

Results: A qualitative binary logistic regression model has been constructed, with the help of which it is possible to predict the probability of criminal recidivism by each of the convicts on the basis of its individual values of the variables included in the model.

Novelty: For the first time in Ukraine, a model has been developed to predict the probability of convicts committing repeated criminal offenses.
Inflation, Inflation Uncertainty and the Economic Growth Nexus: A Review of the Literature

Published: June 2022

Abstract

Research background: Price stability plays a crucial role in ensuring stabilities in the financial markets as well as the real sector. Despite this, questions are still raised, querying if it is either inflation, inflation uncertainty or a combination of both, which affects economic growth? The results obtained, both theoretically and empirically, differ. This paper seeks to revisit and provide both the theoretical and empirical review of literature on the inflation, inflation uncertainty and economic growth nexus.

Purpose: The focus of the paper is centred on the review of theoretical literature, investigating if the differences in findings are attributed to differences in the channels through which inflation and inflation uncertainty is passed over to economic growth; as well as a review of empirical literature, investigating if the source of differences in the findings lies in the separate or joint estimation of inflation and inflation uncertainty on economic growth.

Research methodology: This paper presents an extensive review of scholarly studies on the inflation, inflation uncertainty and economic growth nexus based on their results. The paper analysed, synthesised and critically evaluated previous studies on the inflation, inflation uncertainty and economic growth nexus on both the theoretical and empirical fronts.

Results: In theoretical literature, the study found that the impact of inflation and inflation uncertainty is passed over to economic growth mainly through two channels, which are the price-informative role and the investment spending channel. From the empirical front, studies which separately estimated the role of either inflation or inflation uncertainty on economic growth found mixed results. Studies which estimated the joint impact of both variables on economic growth, arrived at a conclusion that inflation harms economic growth while the literature still remains inconclusive on inflation uncertainty.

Novelty: The study provides an insight into the inflation, inflation uncertainty and economic growth nexus based on a detailed review of literature on the subject based on various transmission channels. Further, it enriches the literature through exploring possible reasons behind the lack of consensus on the impact of inflation and inflation uncertainty on economic growth.

Authors: Stelmakh Svitlana 
Published: June 2022

Prevention of difficult life circumstances is one of the vital areas of work of a social worker. It is confirmed in the new Law of Ukraine, "About Social Services," adopted in 2019. The document defines the organizational and legal framework for the provision of social services, which aim not only to overcome difficult life circumstances but also to prevent them. However, the term "prevention of difficult life circumstances" needs to be clarified.
The article analyzes the fundamental concepts of "difficult life circumstances" and "social prevention", which allowed us to interpret the definition of "prevention of difficult life circumstances". It has been found that the effectiveness of prevention depends not only on reducing risk factors but also on strengthening the protective factors that are most closely related to the problem.
The types of prevention of difficult life circumstances are described, and possible measures are identified that will contribute to the realization of the goals and objectives of each type. Early intervention plays an essential role in primary and secondary prevention, allowing identifying problems in the early stages and preventing their spread and aggravating them.

Проблема суицидальных наклонностей у детей несовершенного возраста является актуальной на протяжении многих лет. В настоящее время дети подвержены разнообразным внешним факторам, которые так или иначе сказываются на их психике и подталкивают к суицидальному поведению. Существуют различные теории, которые объясняют данный феномен. Например, то, что в переходном возрасте у детей присутствуют эмоциональные перепады, связанные с лимбической системой головного мозга, ввиду чего они не в состоянии контролировать свою эмоциональность и импульсивность. Также суицидальные наклонности у подростка могут быть вызваны семейными конфликтами, отсутствием смысла жизни и другими внутренними и внешними факторами. К сожалению, современные родители часто посвящают свое свободное время карьере и другим обязательствам, забывая о том, что их подростку-ребенку необходимо уделять внимание, а также поддерживать с ним доверительные отношения, ведь помимо суицидальных наклонностей ребенок также может страдать аутоагрессией. Кроме того, по статистике, каждый двенадцатый подросток размышлял о суициде, но только некоторые из них обладают истинным желанием свести счеты с жизнью. Именно поэтому суицидальные наклонности в подростковом возрасте являются актуальной проблемой на сегодняшний день.
The problem of suicidal tendencies in underage children has been relevant for many years. Currently, children are exposed to a variety of external factors that in one way or another affect their psyche and push them to suicidal behavior. There are various theories that explain this phenomenon. For example, the fact that in adolescence, children have emotional swings associated with the limbic system of the brain, as a result of which they are not able to control their emotionality and impulsivity. Also, suicidal tendencies in a teenager can be caused by family conflicts, lack of meaning in life, and other internal and external factors. Unfortunately, modern parents often devote their free time to careers and other obligations, forgetting that their teenage child needs to be given attention and maintain a trusting relationship with him, because in addition to suicidal tendencies, the child can also suffer from auto-aggression. In addition, according to statistics, one in twelfth teenagers have thought about suicide, but only a few of them have a true desire to commit suicide. That is why suicidal tendencies in adolescence are an urgent problem today.
