Authors: Sunarjo Lanny , Fatmasari Diyah , Rahmadhani Febby
Published: June 2024

Musculoskeletal diseases and pain (MSDs) is commonly occurred among oral health therapist due to improper working positions. This condition can lead to work-related accidents, lower job satisfaction, and increased healthcare costs. In order to address this issue, ergonomic interventions encompassing cognitive, physical, and organizational aspects have been recommended to prevent the occurrence of MSDs. This study aims to assess the effectiveness of ergonomic interventions, specifically using the "EI" model, in alleviating MSDs among oral health therapists.  The quality assessment related to pain utilized a validated standardized instrument. A purposive sample of 64 oral health therapists, working as dental assistants in Semarang, Indonesia, participated in the study. Data were gathered through a structured questionnaire incorporating the Nordic Body Map to identify the presence of pain. Additionally, a physiotherapist conducted an objective examination, assessing pain levels using the Visual Analog Scale (VAS). The results of the pain complaints test, as indicated by the Nordic Body Map, revealed a significant p-value of 0.001, with ∆ mean = 2.19 for the intervention group and 0.91 for the control group. Similarly, the pain level test using the Visual Analog Scale demonstrated a p-value 0.001, with ∆ mean = 30.38 for the intervention group and 14.91 for the control group. This suggests that the ergonomic model "EI" was significantly effective in reducing complaints of MSDs among oral health therapists.

Published: June 2024

Reduced spontaneous blinking is a recognized Parkinson’s disease (PD) feature. In contrast, voluntary blinking has been less studied and might serve as a measurable marker of facial bradykinesia. We tested 31 PD patients and 31 controls. Participants were filmed during conversation and a rapid blinking task. Both tasks were videorecorded to count the number of blinks per second. PD patients had lower blink rates. Rapid blinking accurately discriminated between groups with 77% sensitivity and 71% specificity. To conclude, rapid blinking may be a simple and quantifiable task of facial bradykinesia.

Published: June 2024

BACKGROUND: Healthcare workers (HCW; e.g., nurses, social workers) work in stressful conditions, a situation that has been further exacerbated by the COVID-19 pandemic. A review of the supportive role of Psychological first aid (PFA) suggested that it can protect HCW from psychological distress. Despite the growing interest of PFA among public health organizations, there is a dearth of literature on its potential impact for the psychological well-being of HCW and its implementation within organizations. OBJECTIVE: This study aimed to evaluate whether PFA met the psychological needs of HCW in Montreal, Quebec. METHODS: A sample of 15 HCW who received PFA by a peer within their organization were recruited to participate in semi-structured interviews. Qualitative research using thematic analysis was conducted. RESULTS: Five themes were identified: 1) PFA satisfied participants’ psychosocial needs; 2) PFA provided by peers allowed participants to feel understood and supported; 3) High availability and multiple modalities facilitated PFA access; 4) Occupational and organizational cultures hindered PFA access; and 5) Recommendations to promote the use of the PFA service. CONCLUSION: Results describe four psychosocial needs met by the PFA intervention: to have resources/strategies, to be validated, to obtain a better understanding of the psychological reactions they were experiencing, and to be guided and supported in their difficulties at work. Overall, these findings illustrate how PFA goes beyond the reduction of distress symptoms in the aftermath of a potentially traumatic event. The relevance to further the assessment of PFA’s positive effects on psychological adaptation and/or recovery is also highlighted.

Published: June 2024

BACKGROUND:

Radiography plays an important role in medical care, and accurate positioning is essential for providing optimal quality images. Radiographs with insufficient diagnostic value are rejected, and retakes are required. However, determining the suitability of retaking radiographs is a qualitative evaluation.

OBJECTIVE:

To evaluate skull radiograph accuracy automatically using an unsupervised learning-based autoencoder (AE) and a variational autoencoder (VAE). In this study, we eliminated visual qualitative evaluation and used unsupervised learning to identify skull radiography retakes from the quantitative evaluation.

METHODS:

Five skull phantoms were imaged on radiographs, and 1,680 images were acquired. These images correspond to two categories: normal images captured at appropriate positions and images captured at inappropriate positions. This study verified the discriminatory ability of skull radiographs using anomaly detection methods.

RESULTS:

The areas under the curves for AE and VAE were 0.7060 and 0.6707, respectively, in receiver operating characteristic analysis. Our proposed method showed a higher discrimination ability than those of previous studies which had an accuracy of 52%.

CONCLUSIONS:

Our findings suggest that the proposed method has high classification accuracy in determining the suitability of retaking skull radiographs. Automation of optimal image consideration, whether or not to retake radiographs, contributes to improving operational efficiency in busy X-ray imaging operations.

A large proportion of the gases from the process units in the casting and furnace bays of ferroalloy plants enter the production facilities, where they form a complex aerodisperse system. The resulting aerosols pose a great danger to the operating personnel due to the presence of toxic and carcinogenic components. To develop emission prevention and elimination methods, the sources of industrial aerosol formation during silicomanganese production, particle size distribution and chemical composition of the dust sludge, the behaviour of the gas-dispersed system in the working area have been analyzed. Scanning electron microscope TESCAN VEGA3 with microanalytical attachment Oxford X-Act was used to study the morphology of dust particles sediment. It was established that the aerodisperse system of the shop atmosphere consists of condensation aerosol with submicron particles of manganese and silicon oxides and dispersion aerosol generated mostly at the transportation and loading of charge materials. The behaviour of particles of silicon and manganese oxides, forming a part of the condensed aerosol in the workshop atmosphere was considered. The motion parameters of particles of various chemical compositions simulating compositions of condensation and dispersion aerosols typical of the working area atmospheric aerosol system were calculated. Time and velocity characteristics of aerosol condensation particles for silicon and manganese oxides of 0.1; 1 and 5 microns in diameter are provided.

This paper assesses the efficiency of metallurgical slag processing at PJSC “MMK” in LLC “Slagservice”, which indicates the need to improve it in terms of increasing the degree of extraction of iron from slag. Proposals for improving the existing technology of steelmaking slag processing and the development of new technologies have been developed. An assessment of the efficiency of the metallurgical slag recycling at LLC “Slakservice” in 2019 is given. Ways to improve the efficiency of steelmaking slag processing in the conditions of existing production are presented. The description of the experimental setup for testing the basic principles of the proposed technology is given. The method of metallurgical slag processing was used in laboratory conditions, it corresponds to the existing technology of metallurgical slag processing in LLC “Slakservice”, including slag crushing, classification by size, metal separation by screening and magnetic separation.It is established that the method of separation of slag-metal conglomerate can be used in industrial conditions. The method of assessing the efficiency of metallurgical slag processing through the degree of extraction of metal-containing components from the slag was used for processing the results. A method of improving the existing technology of steelmaking slag processing is proposed, which includes increasing the content of metallic iron in the current converter slag by means of liquid-phase reduction of iron oxides using coal. The method of increasing the content of metallic iron in the current BOF slag in slag bowls using movable reactors is proposed. This method makes it possible to increase the content of metallic iron in the current BOF slag by about two times, which contributes to increasing the efficiency of magnetic separation at the stage of secondary slag processing.

Loading of iron ore pellets into railway wagons at mining and processing enterprises is accompanied by the formation of a significant amount of suspended iron-containing highly abrasive particles. The shortcomings of existing aspiration systems currently used to reduce the negative impact on the environment are considered. It is demonstrated that existing wet cleaning devices, as a rule, do not meet the requirements of sanitary standards for emissions into the atmosphere. Tubular cloth filter of dry-cleaning devices is subject to intense abrasive wear of the iron ore dust captured, which leads to a violation of sanitary standards for emissions of solid particles into the atmosphere. The results of pilot plant tests of a ceramic filter installed in the existing aspiration system for loading iron ore concentrate into railway wagons are described. The aerodynamic resistance of the ceramic filter is determined, as well as its technical and economic indicators. It was found that when replacing the tubular cloth filter with a ceramic pulse filter, a decrease in the residual dust concentration from 72 to 4 mg/m3 was achieved. The efficiency of cleaning the aspiration flow in a ceramic filter is 17.8 times higher than this indicator in the existing tubular filter. The replacement of cloth filter elements with ceramic ones in the body of the existing filtration system of the aspiration system for loading iron ore pellets into railway cars will reduce the gross emissions of iron-containing dust into the atmosphere from 47 to 1.9 tons/year. When replacing cloth filter elements with ceramic ones, the total fee for the negative impact on the environment within and above the MPE will decrease from 130 thousand roubles/year up to 85 thousand roubles/year. In addition, the return of dust material to production will save at least 0.5 million roubles/year.

Published: June 2024

The deformation behaviour of cast austenitic corrosion-resistant steel type 20Mn–18Cr–3Ni–2Mo–0.4N in the temperature range 1000–1250 °C and strain rates in the range 0.1–10 s–1 has been studied. It is shown that the flow stresses drop with increasing temperature and decreasing strain rate in accordance with the change of the Ziner–Hollomon parameter of the temperature-velocity deformation regime. From the analysis of peak flow stresses, the value of the effective activation energy of hot deformation (Q = 490.3 kJ/mol) required for the calculation of the Ziner–Hollomon parameter is determined. An expression for the peak flow stress in the form of a hyperbolic function of the Ziner–Hollomon parameter was obtained. A comparative evaluation of hot plasticity of austenitic non-magnetic steel by finding the strain value corresponding to the appearance of the first macrocracks on the surface of the specimen is carried out.

ALTERNATIVE DISPUTE RESOLUTION ON CONSUMER CONFLICTS IN THE EU AND TURKEY
Authors: Ünal Yeşilyurt Esra
Published: June 2024

Consumer conflicts arise every day and how to handle this issue is a major part of ensuring consumer redress mechanisms. Because of the workload of courts and the length of cases, Alternative Dispute Resolution (ADR) on consumer conflicts began to occur in the 1970s. The European Union (EU) has always been a supporter of ADR and regulated a specifically Directive with its principles to bring a minimum harmonization duty for member states to ensure a single market. However, because of the general nature of the articles, there have been lots of different approaches and methods in the member states. And, it has become imprecise to understand if it is a good role or effective because of the ambiguous provisions and a variety of approaches.
Turkish Law on Consumer Protection entered into force in 2014 to assure harmonization duty of EU acquis, and it regulated the sui generis procedure of Consumer Arbitration Committees (CAC) and then compulsory mediation on consumer conflicts with an added article in 2020. This article argues that CAC is harmonized with the EU acquis and ADR systems in Turkey bring more effective consumer redress mechanism due to cultural and economic reasons for now even if it is not perfect and has to be improved.
YÜRÜRLÜĞE GİRİŞİNİN OTUZUNCU YILINI GERİDE BIRAKAN 93/13/EEC SAYILI AVRUPA BİRLİĞİ HAKSIZ ŞARTLAR DİREKTİFİ: QUO VADIS?
Authors: Şahin Hale
Published: June 2024

93/13/EEC sayılı Avrupa Birliği Haksız Şartlar Direktifi (Direktif), 5 Nisan 1993 tarihinde yürürlüğe girmiştir. Direktif, tüketicilerin satıcı veya sağlayıcıların sunduğu ve taraflarca bireysel müzakere konusu edilmeyen sözleşme koşullarına karşı etkili bir şekilde korunması ve asgari uyumlaştırma yoluyla iç pazarın kurulmasına katkı sağlanması amacıyla öngörülmüştür. Direktif’in üye devletlerdeki uygulaması, Avrupa Birliği Adalet Divanı’nın (ABAD) ön karar prosedürüyle önüne gelen olaylarda verdiği kararlarla şekillenmektedir. Fakat, ABAD haksız şartlara ilişkin kesin kıstaslar belirlemekten kaçınmaktadır. Bunun yerine, ABAD, haksız şartlar hakkında karar verme işini iç hukuktaki düzenlemeleri dikkate almaları kaydıyla yerel mahkemelere bırakmaktadır. Fakat, üye devletlerin iç hukuk düzenlemeleri birbirinden farklı olduğu için üye devletlerde haksız şart teşkil eden sözleşme hükümleri yeknesak değildir. ABAD’ın haksız şart sayılan sözleşme hükümlerinin hukuki yaptırımına yönelik yorum faaliyeti de Direktif’in yeknesak biçimde uygulanmasını engellemektedir. Çalışmamızda Direktif’in amacı ve uygulama alanı hakkında bilgi verildikten sonra, ABAD kararları ışığında Direktif’in uygulaması üzerinde durulmuş ve Direktif’in uygulamasının bunun öngörülmesindeki amaçlara hizmet edip etmediği incelenmiştir.

Published: June 2024

Avrupa Birliği, evrensel değerler söylemiyle küresel alanda normatif bir güç olma iddiası taşımaktadır. Makalenin temel amacı bu iddianın Avrupa Birliği’nin ayrımcılık yasağı ve eşitlik düzenlemelerindeki karşılığını sorgulamaktır. Bu doğrultuda makalede, Avrupa Birliği’nin biçimsel ve soyut bir çerçeveden eşitlik anlayışı ile eşitlik-özgürlük temelli bir ayrımcılık anlayışına sahip olduğu savunulmaktadır. Eşitlik ve ayrımcılık kavramlarına yönelik bu anlayış ise ayrımcılık yasağı ve eşitlik kavramlarının aynı anlama sahip iki kavram olarak ele alınmasına neden olmakta ve eşitlik, ayrımcılığın yasaklanması ile ulaşılabilen bir hukuksal düzlemde verili bir ilkeye indirgenmektedir. Bu durum ise Avrupa Birliği ayrımcılık yasağı ve eşitlik düzenlemelerinde hiyerarşik eşitlik, kapsam kısıtlamaları ve çoklu ayrımcılığa ilişkin düzenlemelerin olmaması gibi temel eksiklik ve sorunları beraberinde getirmektedir.

The paper presents the results of calculating the crystallization energy and examines its influence on the size of the nanostructured grain during ion-plasma treatment of aluminum (VD17) with oxygen and nitrogen ions. To address this task, we employ a previously proposed model, which considers the impact of individual ions on thermal conductivity and thermoelasticity in the affected area, taking into account their energy, charge, and type. Initially, we estimate the potential number of particles in the nanostructure. Then, we compute the energy required for atomizing the grain from atoms and chemical compounds. By determining the total atomization energy of the grain (Eas), we establish the necessary energy for its formation (Es = 1.1Eas). This energy enables the determination of all characteristics in the ion's action area, such as temperature, temperature rise rate, thermal stresses, strain rate, grain size, volume, and depth of the nanostructure, as well as the actual number of particles in the nanostructure. The calculations demonstrate that the crystallization energy increases the ion energy required to obtain nanostructures. At energies close to 3∙102 eV, it ranges from 0.1 to 7 eV, which can be disregarded, while at energies close to 1.6∙104 eV, crystallization energy ranges from 2.1∙102 to 1.2∙104 eV, with higher values for oxygen ions. Additionally, the calculations show that ion charge significantly affects crystallization energy; for large ion charges, it increases. All of this underscores the necessity of considering crystallization energy only at energies of 2∙103 – 2∙104 eV, allowing refinement of the technological parameters of ion-plasma treatment of aluminum alloys to increase the likelihood of obtaining nanostructures. Furthermore, the ability to determine the sizes of nanostructures allows predicting the physical and mechanical characteristics of surface layers of processed materials. These studies may be of interest to specialists involved in surface strengthening of aluminum alloy surfaces and further research into nanostructures

The article is devoted to ensuring the stability of the technological process of electrohydraulic stamping of thin-sheet large-sized parts. This process is realised on multi-contour EH presses equipped with the capabilities of space-time control of the workpiece load. This control ensures the production of high-quality parts and high technical and economic performance of the process.The control parameters include the geometry of the press energy release zone, the loading sequence of the workpiece sections and the value of the inter-electrode distance. The first parameters change little under specified operating conditions. The third parameter is subject to change over a specified number of discharges due to cavitation and EDM erosion. Violation of the specified value of the interelectrode distance leads to a violation of the energy release mode and its loss.As a result of the experiments, the mechanism of cavitation destruction of the high-voltage insulation of the working electrode was determined and a solution was proposed for the conditions of winding the high-voltage insulation with a glass fibre roving, as well as electrical insulation in the areas adjacent to the discharge zone.Several variants of the design of the end part of the working electrode, which is still directly in the EG discharge zone, were experimentally investigated.The ratio of the duration of the pre-discharge stage to the characteristic time of the discharge circuit was chosen as a criterion parameter of resistance to electrical erosion of the discharge edges. The duration of the pre-discharge stage was determined from the discharge voltage oscillograms.According to the given dependences of the above ratio on the number of discharges, the best design from the considered options was determined.The used value of this ratio for the selected design corresponds to  ~ 2500 discharges at a voltage of 20...25 kV. This number of discharges is on average comparable to the operation during five shifts, after which it is necessary to restore the discharge edges of the electrode. To simplify the operations of changing electrodes, we propose a design in which the electrodes are fixed by clamping them with elastic washers.It is concluded that the goal has been achieved: maintaining stable operation of the EG press with high technical and economic indicators of the entire technological process at a given quality of parts manufacturing.It is concluded that the goal has been achieved: maintaining stable operation of the EG press with high technical and economic indicators of the entire technological process at a given quality of parts manufacturing.Objective of the work - is to evaluate the effectiveness of the proposed technical solutions to increase the stability of the working electrodes and simplify their repair and restoration.

Batch production is typical for engineering enterprises connected with aeronautical engineering manufacturing. One of its main problems is the need to periodically change the production pattern which arises as a result of the instability of the products range, changes in volume of series, moral and physical wear of technological equipment. Such a change is carried out in the course of reconstruction and technical re-equipment in order to improve the efficiency of material flows.The main characteristics of material flows are determined by a spatial component of a flexible manufacturing system pattern, set by the machine tools laying according to the organization of batch process. The bulk of the cost of final product manufacturing is associated with the arrangement of material flows. In order to reduce the total costs it is necessary to improve the pattern of production by establishing a technology-oriented machine tools laying. In this case, there is a need to develop scientific and methodological basis of restructuring the manufacturing process.One of the most effective approaches to the design of machine building plants with a batch type of manufacturing is the use of program-target method based on the methodology of choosing the best technological solutions.Modern methodology of batch technologies design is based on the system approach to the analysis and synthesis of the basic structure of the manufacturing processes, which allows to apply mathematical simulation.The orientation of each of the sites on the end result leads to a substantial reduction of manufacturing costs, which significantly simplifies solving problems of division and coordination of labor on the principles of self-organization and self-regulation.The proposed mathematical model of manufacturing costs optimization is designed in accordance with all the aforementioned principles. The problem being solved is multiobjective. That is why the mathematical model has several goal functions them requiring finding peak values and some of them requiring finding the bottom values.The model can be applied in organizing the aeronautical engineering manufacturing, which requires effective remounting during the change of product range thus ensuring the required flexibility of manufacturing.

Amaç: Bu çalışmada tütün kullanan bireylerin duygu düzenleme güçlük düzeyleri ile psikolojik iyi oluş düzeyleri arasındaki ilişkinin incelenmesi amaçlanmıştır. Yöntem: Bu araştırmanın çalışma grubunu 18-65 yaş arasındaki kişiler oluşturmuştur. Araştırma verileri sanal olarak Google Formlar yoluyla 212 kişiye ulaşılarak toplanmıştır. Veriler araştırmacı tarafından hazırlanan ‘Sosyodemografik Bilgi Formu’ ile ‘Duygu Düzenleme Güçlüğü Ölçeği’ (DDGÖ) ve ‘Psikolojik İyi Oluş Ölçeği’ (PİOÖ) ölçekleri katılımcılara online olarak gönderilmiş olup cevaplamaları istenmiş ve cevaplar değerlendirilerek toplanmıştır. Bulgular: Araştırma kapsamında sigara kullanan 212 katılımcının verileri incelenmiştir. Katılımcıların sosyodemografik değişkenlerinin duygu düzenleme güçlüğü ve psikolojik iyi oluş düzeyleriyle karşılaştırılmıştır. Ayrıca, sigara kullanan bireylerin duygu düzenleme güçlükleri ve psikolojik iyi oluş düzeyleri arasındaki ilişki incelenmiştir. Araştırmada elde edilen bulgulara göre, cinsiyet, medeni durum, çalışma durumu, gelir düzeyi, psikolojik rahatsızlık, ailede sigara içen bireyin olması durumu, sigara içme sebebi değişkenleri bakımından psikolojik iyi oluş ve duygu düzenlemede güçlükler puanlarında anlamlı farklılıklar saptanmıştır. Sonuç: Sigara kullanan bireylerde Psikolojik iyi oluş ile duygu düzenleme güçlüğü arasında negatif yönlü, orta düzeyde ve anlamlı ilişki saptanmıştır. Duygu düzenleme güçlüğü toplam puanı psikolojik iyi oluş puanlarını negatif yönlü ve anlamlı düzeyde yordamaktadır. Oluşturulan model varyansı %14 oranında açıklamaktadır. Duygu düzenleme güçlüğü alt boyutlarının psikolojik iyi oluş puanlarını yordayıcılığına ilişkin bulgulara göre, duygu düzenleme stratejileri geliştirmede güçlük puanlarının psikolojik iyi oluş puanlarını negatif yönlü ve anlamlı düzeyde yordadığı bulunmuştur. Oluşturulan model varyansı %16 oranında açıklamaktadır.

Yöntem: Bu araştırmanın katılımcılarını madde kullanım bozukluğu tedavisi için NPİSTANBUL Beyin Hastanesi Amatem servisine başvuran 50 kişi oluşturmaktadır. Bu 50 katılımcının 47’si erkek ve 3’ü kadındır. Araştırma verileri anket katılımcılara verilen ölçekler aracılığıyla toplanmıştır. Katılımcılara, bağımlılık şiddetini ölçmek için Bağımlılık Profil İndeksi (BAPİ), travmatik yaşantılarını ölçmek için Travmatik Yaşantılar Ölçeği (TYÖ) uygulanmıştır. Bulgular: Araştırmada anlamlılık düzeyi 0.05 ve 0.001 düzeyinde alınmıştır. Katılımcıların travmatik yaşantılar puanları ile bağımlılık indeksi toplam puanları arasında pozitif yönlü orta düzeyde anlamlı ilişki bulunmuştur. Sonuç: Araştırmada elde edilen bulgulara göre, erkek katılımcılarda bağımlılık indeksi tanı alt boyutu puanları kadın katılımcılara kıyasla daha yüksek bulunmuştur. Çocukluk çağı travmalarının nöral yapı ve işlevi bozarak bireyleri bilişsel eksikliklere ve madde bağımlılığı da dahil olmak üzere psikiyatrik hastalıklara karşı daha duyarlı hale getirdiği gösterilmiştir. Bu nedenle, madde bağımlılığı ile ilişkili olarak çocukluk çağı travmatik deneyimlerinin geçmişini değerlendirmek ve dikkate almak önemlidir. Elde edilen sonuçlar, bağımlılık tedavisine yönelik geliştirilecek uygulamalara ve gelecekte yapılacak araştırmalara katkı sunabilecek ölçüde travmatik yaşantıların bağımlılıklarda önemini vurgulamaktadır.

КЛІНІЧНЕ МИСЛЕННЯ АНДРЕ ҐРІНА
Authors: Павловська Ольга
Published: June 2024

Анотація. У статті авторка запрошує читачів простежити за теоретичними пошуками французького психоаналітика Андре Ґріна. Він створив оригінальну клінічну модель, яка дозволяє зрозуміти психічне функціонування не-невротичних аналізантів. Пошук нових форм клінічного психоаналітичного мислення є ключовим мотивом теоретичних розробок А. Ґріна. Формулювання А. Ґріна спираються на метапсихологію Фройда, але вони впевнено підштовхують наше психоаналітичне мислення у бік теорії репрезентацій, процесів символізації та нерепрезентованого в психіці людини. Тому відомі концептуальні ідеї А. Ґріна є лише часткою його загального інтересу та теоретичної психоаналітичної структури. Сучасний суб’єкт психоаналізу відрізняється від фройдівського суб’єкта психоаналізу. А. Ґрін у своїх роздумах про сучасне клінічне поле звертає увагу на зміну культурних епох, на те, яка саме соціальна думка формує у сучасному світі стосунки між людьми, відносини з власним тілом і взагалі із задоволенням. Він підкреслює негативістські реакції сучасного суб’єкта, які породжені тим соціальним порядком, в якому він існує, зараз ми стикаємось з делегітимізацією поняття влади, атомізацією соціальних зв’язків та нігілізмом. Ревізія Ґріном клінічного поля ставить роботу негативу в центр сучасної психоаналітичної практики. Ключовими внесками А. Ґріна в психоаналітичне розуміння психічного функціонування не-невротичних пацієнтів є відомі концепти: дуального нарцисизму, мертвої матері, роботи негативу, потягу до смерті, афектів, об’єкталізація-дезоб’єкталізація. Авторка підкреслює, що клінічне мислення Андре Ґріна є процесом, який утримує динамічну єдність психоаналітичних моделей, які описують роботу з невротичними – модель сновидіння та не-невротичними аналізантами – модель дії. А. Ґрін обґрунтовує існування третинних процесів, які є основою символізації.
РОЛЬ ОБ’ЄКТА У ПРОЦЕСІ СИМВОЛІЗАЦІЇ НЕСВІДОМОЇ ВТРАТИ
Authors: Артюхова Маргарита
Published: June 2024

Анотація. У статті авторка зосереджується на розгляді ролі об’єкта в процесі символізації несвідомої втрати в контексті психоаналітичної практики. Вступна частина підкреслює важливість цієї проблематики для розуміння складних процесів психічної реконструкції та їх застосування в аналітичній роботі. Авторка зазначає, що роль об’єкта як у формуванні внутрішньої відсутності, так і в її подоланні є важливим аспектом у роботах психоаналітиків різних часових періодів. Наприклад, Фройд (Freud, 1917) у своїй праці «Скорбота і меланхолія» підкреслює відмінність між сумом і меланхолією, пов’язуючи це з втратою об’єкта і втратою самого «Я». Інші дослідники, такі як Мелані Кляйн (Klein, 1959, 2011) та Дональд Віннікотт (Winnicott, 1960, 1991, 2018), підкреслюють важливість прихильності до первинного об’єкта у формуванні психічного досвіду суб’єкта. Роботи Франсуази Дольто (Dolto, 1998, 2002) і Віктора Франкла (Frankl, 1967, 1984) фокусуються на символізації відсутності та пошуку сенсу в житті. Рене Руссійон, досліджуючи вплив ранніх травм на психіку, наголошує на важливості реконструкції історичних травм аналітиком для розуміння їх впливу на психічну організацію пацієнта, навіть якщо ці травми не усвідомлюються пацієнтом, вони все одно впливають на нього, «гублячись» у несвідомому (Roussillon, 2005, 2012). У пошуку відповіді на питання, що ж таке несвідома втрата, авторка звертається до концепції «мертвої матері», введеної Ґріном (Green, 1993), як метафори материнської депресії та її впливу на емоційний розвиток дитини. Також у цій статті авторка розглядає ідеї Андре Ґріна (Green, 1975), які підкреслюють важливість символізації того, чого ніколи не було – нерепрезентованого. Головний акцент у статті зроблено на внутрішніх змінах аналітика та їхньому впливі на пацієнта, а також на проблемі індикацій до аналізу. Авторка наголошує на важливості аналітичного сетингу та створення умов для формування аналітичного об’єкта через символізацію внутрішньої порожнечі. Прикінцева частина статті підкреслює актуальність подальшого дослідження цієї теми з метою розвитку психоаналітичної практики та глибшого розуміння механізмів несвідомої втрати.

Toxoplasma gondii is a unique intracellular parasite, which infect a large proportion of the world, population, butclinically un commonly causes significant disease. The present study was performed for the first time in Thi-Qarprovince to estimate the prevalence of toxoplasmosis among university students . Venous blood samples were collected from 319 (111 males and 208 females) apparently healthy students ,they have ages between (18-42) years attended from different colleges of Thi-Qar university-Iraq, during the period from October 2013 to April 2014. Enzyme linked Immunosorbant Assay (ELISA), was used to evaluate the presence of anti-Toxoplasma IgM and IgG antibodies and detection of B1 gene of T.gondii DNA by Real-Time Polymerase Chain Reaction(RT-PCR). The results indicated that 70 (21.94%) of students were exposed positive for anti-Toxoplasma antibodies,17 (5.33%) of them had IgM,38 (11.91%) had IgG, and 15 (4.70%) had both IgM and IgG. Statistically, significant difference between them. The results showed significant difference between males and females in rate of positive for anti- Toxoplasma antibodies,  which recorded 24 (7.52%) and 46 (14.42%) respectively . Besides the serological diagnosis of T.gondii Real-Time PCR  (RT-PCR) technique was used to confirm the infection with T.gondii by detection B1 gene of T.gondii DNA in the blood of students. out of 319 students only 6.26% showed positive toxoplasmosis among those 8(2.50%)were males  and 12(3.76%) were females. The positive result in RT-PCR analysis were distributed on the patterns of the antiToxoplasma antibodies by ELISA test , it was no found any positive blood samples with IgM,IgG.
