Metode yang digunakan dalam penelitian ini adalah metode kuantitatif, metode statistika berupa teknik sampling dengan jenis purposive sampling, serta metode pengolahan datanya yaitu angket dan studi pustaka. Hasil penelitian menunjukkan sebanyak 37,5% responden memilih skala 4 dari 5. Penyampaian pesan melalui fotografi fine art pun dapat ditangkap dengan baik oleh para responden yang menunjukkan kesamaan makna yaitu sebuah kegembiraaan. Dengan demikian implementasi aliran seni rupa ekspresionisme pada fotografi fine art sudah diterapkan dengan baik. Implementation of The Flow of Expressionism in Fine Art Photography ABSTRACT Expressionism is a form of art that assumes that art that flows spontaneously from an artist is not a copy of nature. Fine art photography or art photography is an activity to send a message of what the artist feels to the recipient through the beauty contained in a photo that aims to change the perspective of others. The purpose of this research is to create and find out the respondents' views from the results of expression photography that uses the characteristics of one of the art schools, namely expressionism. The method used in this research is a quantitative method, statistical method is in the form of sampling technique with purposive sampling type, and the data processing method is questionnaire and literature study. The results showed that 37.5% of respondents chose a scale of 4 out of 5. The delivery of messages through fine art photography could also be captured well by the respondents who showed the same meaning, namely a joy. Thus, the implementation of the flow of expressionism in fine art photography has been well implemented.
Linguistic Methods of Implementing a Communicative Strategy of Self-Defense in American Political Discourse
Authors: Khlopotunov Ya. Y.
Published: June 2022

This paper aims to study linguistic techniques of the communicative strategy of self-defense as one of the confrontational communicative strategies of American political discourse. The relevance of the study is revealed in the transformation of modern American political rhetoric, the consequence of which is the intensification of conventionally destructive elements in American political rhetoric and the predominance of subjective-negative modality units in political speech. The communicative strategy of self-defense allows the communicant to divert negative information from themselves and move from a defensive position to an attack. The author analyzes various tactical ways of implementing a communicative strategy of self-defense, which include justification, challenging, retaliatory criticism (counter-accusation), indignation, and opposition. They include several linguistic means (lexical units with a negative evaluation, deictic constructions, spoken words, lexical repetitions, personal pronouns, gradation, etc.). This article examines the roles of participants in the speech act of confrontation. The following models of speech behavior can be distinguished: offensive (attack, provocation), defense (self-defense, reaction to provocation), and evaluation (based on observation of the conflict). Thanks to the implementation of the communicative strategy of self-defense, the transition of the communicant from defense to offensive is possible.

There are more than 1.6 billion people in the world with various types of refraction. Dysfunction of the eye color function is a consequence of the pathology of the retina and optic nerve. Myopia ranks first among the types of refractive errors, accompanied by a high probability of complications. Thanks to the early screening of students, we were able to identify changes in refractive errors, and as a result, to form an exemplary algorithm for preventive and typed treatment. Purpous.To assess the role of timely diagnosis in the detection of diseases of the organ of vision. Timely predict the likelihood of diseases of the optic nerve and retina. Material and methods. The study involved 53 people, 20 female students (79 %), 7 male students (21 %). In young men, the right eye is myopia 60 %, emmetropia 20 %, hyperopia 20 %, left eye myopia 60 %, emmetropia 20 %, hyperopia 20 %. In girls, the left eye: myopia 73 %, emmetropia 22 %, hyperopia 5 %, right eye: myopia 75 %, emmetropia 20 %, hyperopia 5 %. Results. The analysis showed that the number of errors (right eye) had no statistically significant changes (p = 0.686), visual acuity (right eye) showed statistically significant changes (p = 0.029), and visual acuity (left eye) had statistically significant changes (p = 0.008), the number of errors (left eye) did not show statistically significant changes (p = 0.154). Conclusions. Today, the problem of violation of refractive in young people is a significant problem. Introspection-based functional tests such as the FM 100 make it possible to monitor disorders at the retinal and optic nerve levels.

Purpose. Analysis of the results of optical coherence tomography (OCT) of the anterior segment of the eye in patients with chronic keratoconjunctivitis in the post-covid period. Material and methods. We observed 11 patients (11 eyes) with keratoconjunctivitis. The age of the patients ranged from 20 to 61 years. The control group consisted of 10 healthy individuals (10 eyes). All these subjects underwent standard ophthalmic examination involving visometry, pneumotonometry, perimetry, biomicroscopy, B-scanning and ophthalmoscopy. Results. On the epithelial map of the anterior OCT, a thickening of the epithelial layer of the cornea up to 84 µm was revealed in 9 patients with a norm of 71 µm. A thickening of the epithelial layer by 13.2 % was noted compared with the control group. When the total thickness of the cornea in patients with keratoconjunctivitis was measures, a slight increase in all layers was observed, while the thickness of the cornea was 565 ± 6.3µm. Therefore, this figure was 5 % higher than normal values. The epithelial layers of the cornea increased more than the entire corneal stroma in patients with keratoconjunctivitis in the post-covid period. Conclusion. Patients with keratoconjunctivitis in the post-covid period showed an increase in the epithelial layers of the cornea by 13.2 % compared to the entire thickness of the cornea. Keywords: keratoconjunctivitis, postcovid period, anterior optical coherence tomography.

Published: June 2022

Purpose. To assess the influence of the localization of cranio-orbital injuries (COI) on the frequency and level of damage to the visual analyzer. Material and methods. In the emergency neurosurgical department of the FFRCEMC, we observed 115 patients with COP aged 18 to 70 years (men – 92, women – 23). The main causes of injuries were: traffic accidents – 46 (40 %), domestic injury 21 (18.2 %), criminal situation 34 (29.5 %). All patients studied history, performed a comprehensive ophthalmological examination: visometry (with optimal correction), refractometry, biomicroscopy, ophthalmoscopy, tonometry, perimetry. Results. Concussion was diagnosed in 51 (44.3 %) patients. Brain contusions were found in 50 (43.4 %) patients, with a predominant lesion of the frontal lobes – in 35 (30.4 %) patients. Epidural, subdural hematomas – in 31 (26.9 %) patients. Intracerebral hematomas were detected in 12 (10.4 %) patients. Conclusion. It is possible to predict the results of treatment of damage to the optic nerve only when the nature and severity are established. Severe cranioorbital damage, tear, rupture, detachment of the optic nerve, unfortunately, has a very unfavorable prognosis - from a significant degree of vision loss to complete loss of vision and the eye as an organ. Keywords: optic nerve, orbital fracture, visual analyzer contusion.

Authors:   Department of Ophthalmology, Military Medical Academy, St. Petersburg, Russia, Zhalimova V.R.
Published: June 2022

Purpose. To study morphological and functional outcomes in patients with neovascular age-related macular degeneration (nAMD) and low visual acuity violating the treatment regimen. Material and methods. Treatment-naive patients as well as patients receiving anti-VEGF therapy with best-corrected visual acuity (BCVA) less than 0.1 were included. Demographic characteristics, changes in BCVA, central retinal thickness (CRT) and structural changes on optical coherence tomography (OCT) were evaluated baseline and at the of the study period. Results. BCVA changed not statistically significantly at the end of the study period in all groups (р > 0.05). A statistically significant decrease of CRT was found only in the group of treatment-naive patients (р = 0.03). Atrophy of the retinal pigment epithelium and subretinal fibrosis were most common among structural changes in advanced nAMD with low visual acuity. These morphological changes persisted by the end of the observation period, without statistically significant changes in the frequency of occurrence. Conclusion. Low visual acuity in patients with advanced nAMD is associated with severe irreversible structural changes in the macula. The use of anti-VEGF therapy in patients with low functional status and severe changes in the macula appears to be unpromising. Keywords: age-related macular degeneration, antiangiogenic therapy, optical coherence tomography, retinal pigment epithelium atrophy, subretinal fibrosis.

Chalazia is a chronic granulomatous inflammation of the eyelid cartilage caused by blockage of the excretory duct of the meibomian gland. When inflamed, a chalazia can cause cosmetic discomfort, conjunctivitis, and if it is large enough, it can lead to induced astigmatism due to pressure on the cornea and visual impairment. Available methods of treatment are divided into non-invasive (conservative): hot compresses, local anti-inflammatory and antibacterial treatment; and invasive: local administration of prolonged glucocorticosteroids and opening of the chalazia capsule with curettage of the contents. Up to date, there is no consensus on a specific algorithm for the treatment of chalazia. This is due to the fact that, firstly, the etiology of this disease is not always obvious, and secondly, there is no unified theoretical and methodological base and an extremely small number of studies and scientific articles on this topic, especially in Russia. In this article, based on the analysis of randomized clinical trials, we compare different methods of treatment and generalize them into some algorithm. Conservative treatment can be used as first-line therapy in patients with new onset chalazia lasting less than 2 months. If there is a chalazia for more than 2 months, it is more advisable to start treatment with invasive methods. In a chronic recurrent course, as well as with signs of a festering chalazia, the surgical method is a priority, which will minimize the risk of relapse. Keywords: chalazia, conservative treatment, intralesional injections, opening and curettage of chalazia.

To determine the changes in the morphofunctional parameters of the aphakic eye in RRD, the following goals were set. Purpose. To determine the features of the structural parameters of the anterior eye, namely the angle of the anterior chamber and the depth of the anterior chamber. Material and methods. Depending on the method of correction of the defect in the capsular-ligamentous apparatus of the lens against the background of silicone tamponade of the vitreal cavity, the patients were divided into 4 groups: group 1 – patients with anterior chamber IOLs, group 2 – patients with transsclerally fixed IOLs, group 3 – patients with aphakia, group 4 artifakia (control). For a detailed study of the change in indicators from the anterior chamber, emphasis was placed on two indicators, namely the angle of the anterior chamber and the depth of the anterior chamber. The depth of the anterior chamber was measured from the iris to the corneal endothelium at 2 mm from the anterior chamber angle point. Results. When examining the features of changes in the APC in different groups, a tendency for this indicator to change when using an anterior chamber IOL, relative to the control group, is revealed, in particular, this parameter is significantly lower in the temporal sector: APC 3(T) in the 1st group is less than in the 4th group by 7.73 (p = 0.036) degrees. A similar trend in this sector was found in patients with transscleral fixation of the IOL: AEC 3(T) in the 3rd group was less than in the 4th group by 8.73 (p = 0.028) degrees. Conclusion. In a general analysis of the dynamics of the HPC indicators, depending on the correction of the CCA defect, general trends are identified that characterize each group. In particular, in patients using the anterior chamber IOL (group 1), a decrease in this parameter in sector S is detected, relative to the indicators of the control group (group 4) and the group using transscleral fixation of the IOL (group 3). When using the anterior chamber IOL, a change in the position of the iris is observed due to the pressure of the silicone bubble from the vitreous cavity. Keywords: retinal detachment, intraocular lens, anterior chamber.

The aim of the study is to develop a polymeric microshunt of an original design and estimate the clinical effect of its using for the surgical treatment of worsening and terminal open-angle glaucoma. Material and мethods. 30 patients (30 eyes) with open-angle glaucoma and high level of intraocular pressure (IOP) were observed. All the patients were given modified partial-thickness deep sclerectomy with the polymeric microshunt implantation by means of the developed insertor. The shunt made of polymer (polycarbonate methacrylate) is a hollow square tube 2.5 mm long, the diameter of the inner hole is 0.2 mm. The needle cut angle is 45 degrees, the end of the needle has an additional lateral anti-lock hole. The microshunt consists of two parts: the needle for placing into the anterior chamber and supporting elements for the shunt fixation between the superficial and deep layers of the sclera. The insertor we created is an instrument 12.2 mm long with the 2.2 mm long thin rod at the end. Before implantation the shunt put on the needle is securely fixed due to the working part of the tool cut (45 degrees), which is congruent to the external part of the shunt. After the implantation the needle is removed from the shunt by pressing the side button of the insertor that allows to leave the shunt at the implantation site. Results. All the patients demonstrated good results at a distant time with areactive current of postoperative period. Computer static projector perimetry and visometry didn't reveal any negative dynamics during the entire observation period. According to ophthalmoscopy and optical coherent tomography results, the changes of the optic disc, ganglion cells layer in the macula and peripapillary nerve fibers remained at the same level. Conclusion. Antiglaucomatous surgery according to the invented technology of the polymeric shunt implantation with the help of the original insertor in combination with modified sclerectomy provides stable hypotensive effect and minimizes complications. In addition, the method helps to stabilize visual functions in patients with worsening and terminal open-angle glaucoma and high level of IOP.

This research is based on conditions in which there are still many deficiencies in the management process, there are still many assets of the Meranti Islands Regency Education and Culture Office that have not been properly recorded and recorded, so that the true value of assets is difficult to know and the whereabouts of these assets are difficult to trace. Apart from that, the information regarding the reporting of assets at the agency is not accurate. As for the purpose of the research is to find out whether the management of regional assets at the agency has been running well in accordancewith the applicable regulations and what obstacles are faced in the implementation of regional asset management at the Department of Education and Culture of the Meranti Islands Regency. In this study, the authors used the theoretical concepts put forward by George R. Terry, planning, organizing, actuating and controlling. The form or method used in this research is qualitative. While the data collection technique is done through observation, interview and documentation methods. The results of this study indicate that the regional asset management at the Meranti Islands District Educationand Culture Office has not been fully implemented optimally as regulated in statutory regulations, especially in data collection on the number of regional assets owned and the systems and procedures for managing regional assets. This is due to the lack of Standard Operating Procedures (SOP), not having a warehouse where assets are stored, not having conducted an assessment and evaluation of asset managers and a lack of experts in regional asset management. For this reason, the Meranti Islands Regency Education and Culture Office should have a Standard Operating Procedure (SOP) forregional asset management, and have a special warehouse for storing regional assets. Assess and evaluate the performanceof the asset manager periodically/quarterly and give appreciation or appreciation to the performance of regional assetmanagers in spurring morale and increasing a sense of responsibility, involving asset managers in trainings and having a special Accounting Staff in charge of assets.

Türkiye tarımında yaşanan önemli sorunlardan biri ürünlerin pazarlanmasıyla ilgilidir. Bu nedenle, mevcut durum analizine dayalı uygulanabilir önerilerin geliştirilmesi sürdürülebilir bir pazarlama siteminin kurulabilmesi için önemlidir. Bu çalışmanın amacı mikro klima özelliğinden dolayı oldukça yüksek bitkisel üretim potansiyeline sahip olan Iğdır ilinde bitkisel üretim yapan çiftçilerin ürün gruplarına göre üretim ve pazarlama yapısını tespit ederek bu alanda yaşanılan sorunlara çözüm önerileri getirmektir. Basit Tesadüfi Örnekleme Yığın Oran Tahmini Yöntemi kullanılarak belirlenen 237 çiftçi ile 2019 yılı üretim döneminde yapılan anket çalışmasından elde edilen veriler çalışmanın ana materyalini oluşturmaktadır. Araştırma sonuçlarına göre tarla ürünlerinden buğday ve arpa önemli oranda Toprak Mahsulleri Ofisi (TMO) aracılığı ile silajlık mısır, dane mısır ve pamuk ise tüccar aracılığı ile pazarlanmaktadır. Domates, salatalık, kayısı ve elma gibi yaş meyve ve sebzelerin pazarlanması ise büyük ölçüde komisyoncu ve tüccar kanalıyla yapılmaktadır.

Verification of Knowledge-Based Programs over Description Logic Actions
Authors: Zarrieß Benjamin , Claßen Jens
Published: June 2022

A knowledge-based program defines the behavior of an agent by combining primitive actions, programming constructs and test conditions that make explicit reference to the agent’s knowledge. In this paper we consider a setting where an agent is equipped with a Description Logic (DL) knowledge base providing general domain knowledge and an incomplete description of the initial situation. We introduce a corresponding new DL-based action language that allows for representing both physical and sensing actions, and that we then use to build knowledge-based programs with test conditions expressed in the epistemic DL. After proving undecidability for the general case, we then discuss a restricted fragment where verification becomes decidable. The provided proof is constructive and comes with an upper bound on the procedure’s complexity.
Approximate Unification in the Description Logic FL₀
Authors: Baader Franz , Marantidis Pavlos , Okhotin Alexander
Published: June 2022

Unification in description logics (DLs) has been introduced as a novel inference service that can be used to detect redundancies in ontologies, by finding different concepts that may potentially stand for the same intuitive notion. It was first investigated in detail for the DL FL₀, where unification can be reduced to solving certain language equations. In order to increase the recall of this method for finding redundancies, we introduce and investigate the notion of approximate unification, which basically finds pairs of concepts that “almost” unify. The meaning of “almost” is formalized using distance measures between concepts. We show that approximate unification in FL₀ can be reduced to approximately solving language equations, and devise algorithms for solving the latter problem for two particular distance measures.
Metric Temporal Description Logics with Interval-Rigid Names (Extended Version)
Authors: Baader Franz , Borgwardt Stefan , Koopmann Patrick , Ozaki Ana , Thost Veronika
Published: June 2022

In contrast to qualitative linear temporal logics, which can be used to state that some property will eventually be satisfied, metric temporal logics allow to formulate constraints on how long it may take until the property is satisfied. While most of the work on combining Description Logics (DLs) with temporal logics has concentrated on qualitative temporal logics, there has recently been a growing interest in extending this work to the quantitative case. In this paper, we complement existing results on the combination of DLs with metric temporal logics over the natural numbers by introducing interval-rigid names. This allows to state that elements in the extension of certain names stay in this extension for at least some specified amount of time.
Repairing Description Logic Ontologies by Weakening Axioms
Authors: Baader Franz , Kriegel Francesco , Nuradiansyah Adrian , Peñaloza Rafael
Published: June 2022

The classical approach for repairing a Description Logic ontology O in the sense of removing an unwanted consequence α is to delete a minimal number of axioms from O such that the resulting ontology O´ does not have the consequence α. However, the complete deletion of axioms may be too rough, in the sense that it may also remove consequences that are actually wanted. To alleviate this problem, we propose a more gentle way of repair in which axioms are not necessarily deleted, but only weakened. On the one hand, we investigate general properties of this gentle repair method. On the other hand, we propose and analyze concrete approaches for weakening axioms expressed in the Description Logic EL.
Actions with Conjunctive Queries: Projection, Conflict Detection and Verification
Authors: Koopmann Patrick
Published: June 2022

Description Logic actions specify adaptations of description logic interpretations based on some preconditions defined using a description logic. We consider DL actions in which preconditions can be specified using DL axioms as well as using conjunctive queries, and combinatiosn thereof. We investigate complexity bounds for the executability and the projection problem for these actions, which respectively ask whether an action can be executed on models of an interpretation, and which entailments are satisfied after an action has been executed on this model. In addition, we consider a set of new reasoning tasks concerned with conflicts and interactions that may arise if two action are executed at the same time. Since these problems have not been investigated before for Description Logic actions, we investigate the complexity of these tasks both for actions with conjunctive queries and without those. Finally, we consider the verification problem for Golog programs formulated over our famility of actions. Our complexity analysis considers several expressive DLs, and we provide tight complexity bounds for those for which the exact complexity of conjunctive query entailment is known.
The distributive, graded lattice of EL concept descriptions and its neighborhood relation (Extended Version)
Authors: Kriegel Francesco
Published: June 2022

For the description logic EL, we consider the neighborhood relation which is induced by the subsumption order, and we show that the corresponding lattice of EL concept descriptions is distributive, modular, graded, and metric. In particular, this implies the existence of a rank function as well as the existence of a distance function.
Projection in a Description Logic of Context with Actions (Extended Version)
Authors: Tirtarasa Satyadharma , Zarrieß Benjamin
Published: June 2022

Projection is the problem of checking whether the execution of a given sequence of actions will achieve its goal starting from some initial state. In this paper, we study a setting where we combine a two-dimensional Description Logic of context (ConDL) with an action formalism. We choose a well-studied ConDL where both: the possible states of a dynamical system itself (object level) and also different context-dependent views on this system state (context level) are organised in relational structures and can be described using usual DL constructs. To represent how such a system and its views evolve we introduce a suitable action formalism. It allows to describe change on both levels. Furthermore, the observable changes on the object level due to an action execution can also be contextdependent. We show that the formalism is well-behaved in the sense that projection has the same complexity as standard reasoning tasks in case ALCO is the underlying DL.
Practical Query Rewriting for DL-Lite with Numerical Predicates (Extended Version)
Authors: Alrabbaa Christian , Koopmann Patrick , Turhan Anni-Yasmin
Published: June 2022

We present a method for answering ontology-mediated queries for DL-Lite extended with a concrete domain, where we allow concrete domain predicates to be used in the query as well. Our method is based on query rewriting, a well-known technique for ontology-based query answering (OBQA), where the knowledge provided by the ontology is compiled into the query so that the rewritten query can be evaluated directly over a database. This technique reduces the problem of query answering w.r.t. an ontology to query evaluation over a database instance. Specifically, we consider members of the DL-Lite family extended with unary and binary concrete domain predicates over the real numbers. While approaches for query rewriting DL-Lite with these concrete domain have been investigated theoretically, these approaches use a combined approach in which also the data is processed, and require the concrete domain values occurring in the data to be known in advance, which makes the procedure data-dependent. In contrast, we show how rewritings can be computed in a data-independent fashion.
On the Complexity and Expressiveness of Description Logics with Counting
Authors: Baader Franz , De Bortoli Filippo
Published: June 2022

Simple counting quantifiers that can be used to compare the number of role successors of an individual or the cardinality of a concept with a fixed natural number have been employed in Description Logics (DLs) for more than two decades under the respective names of number restrictions and cardinality restrictions on concepts. Recently, we have considerably extended the expressivity of such quantifiers by allowing to impose set and cardinality constraints formulated in the quantifier-free fragment of Boolean Algebra with Presburger Arithmetic (QFBAPA) on sets of role successors and concepts, respectively. We were able to prove that this extension does not increase the complexity of reasoning. In the present paper, we investigate the expressive power of the DLs obtained in this way, using appropriate bisimulation characterizations and 0–1 laws as tools to differentiate between the expressiveness of different logics. In particular, we show that, in contrast to most classical DLs, these logics are no longer expressible in first-order predicate logic (FOL), and we characterize their first-order fragments. In most of our previous work on DLs with QFBAPA-based set and cardinality constraints we have employed finiteness restrictions on interpretations to ensure that the obtained sets are finite, as required by the standard semantics for QFBAPA. Here we dispense with these restrictions to ease the comparison with classical DLs, where one usually considers arbitrary models rather than finite ones, easier. It turns out that doing so does not change the complexity of reasoning.
Using model theory to find w-admissible concrete domains
Authors: Baader Franz , Rydval Jakub
Published: June 2022

Concrete domains have been introduced in the area of Description Logic to enable reference to concrete objects (such as numbers) and predefined predicates on these objects (such as numerical comparisons) when defining concepts. Unfortunately, in the presence of general concept inclusions (GCIs), which are supported by all modern DL systems, adding concrete domains may easily lead to undecidability. One contribution of this paper is to strengthen the existing undecidability results further by showing that concrete domains even weaker than the ones considered in the previous proofs may cause undecidability. To regain decidability in the presence of GCIs, quite strong restrictions, in sum called w-admissiblity, need to be imposed on the concrete domain. On the one hand, we generalize the notion of w-admissiblity from concrete domains with only binary predicates to concrete domains with predicates of arbitrary arity. On the other hand, we relate w-admissiblity to well-known notions from model theory. In particular, we show that finitely bounded, homogeneous structures yield w-admissible concrete domains. This allows us to show w-admissibility of concrete domains using existing results from model theory.
Answering Regular Path Queries Under Approximate Semantics in Lightweight Description Logics
Authors: Gil Oliver Fernández , Turhan Anni-Yasmin
Published: June 2022

Classical regular path queries (RPQs) can be too restrictive for some applications and answering such queries under approximate semantics to relax the query is desirable. While for answering regular path queries over graph databases under approximate semantics algorithms are available, such algorithms are scarce for the ontology-mediated setting. In this paper we extend an approach for answering RPQs over graph databases that uses weighted transducers to approximate paths from the query in two ways. The first extension is to answering approximate conjunctive 2-way regular path queries (C2RPQs) over graph databases and the second is to answering C2RPQs over ELH and DL-LiteR ontologies. We provide results on the computational complexity of the underlying reasoning problems and devise approximate query answering algorithms.
