A narrative, based on a journey through the physical geography of Europe, but also a journey on the signs of a European future identified in the space travelled, will be an opportunity for balances that will allow the traveller to think about Europe. This intervention will seek to pay attention to the lines of reflection outlined in this work.
Percursos europeus pela lente de Tiago Salazar em A Casa do Mundo. Deambulações pela Europa: um olhar contemporâneo
Authors: Soares Maria Dulce Pinto
Published: October 2023

This paper focuses on the analysis of the travel narrative A Casa do Mundo. Deambulações pela Europa (2008) by Tiago Salazar, taking Europe in the early twenty-first century as its stage. By allowing multi-focused dialogues of a cultural, identity, imagological and textual nature, among others, this work proves to be a fertile territory for rethinking the images of an Old Continent, in constant rediscovery. Thus, starting from an affective cartography, from lived experience and the specificity of the author’s gaze, I will try to problematize issues arising from the encounter between cultures, which stand as key pillars in the questioning of the Self and the Other, in a journey through the textual space, where a porous and fluid writing emerges, betting on the convergence between reality and fiction or just in a “frictional literature” (Ette 2003: 31).
THE CARDIOPROTECTIVE EFFECTS OF EMPAGLIFLOZIN IN PATIENTS WITH HEART FAILURE WITH PRESERVED EJECTION FRACTION AND TYPE 2 DIABETES MELLITUS
Authors: Андрій Геращенко  , Сергій Федоров
Published: October 2023

Introduction. Heart failure with preserved ejection fraction (HFpEF) is a complex clinical syndrome associated with significant morbidity and mortality. Type 2 diabetes mellitus (T2DM) often coexists in patients with HFpEF, further exacerbating the cardiovascular risk. Empagliflozin, a sodium-glucose cotransporter 2 inhibitor, has shown promising results in improving cardiovascular outcomes in patients with T2DM. However, the specific cardioprotective effects of empagliflozin in patients with HFpEF and T2DM remain to be elucidated.

Aim. To assess the effect of empagliflozin on biochemical markers of heart failure in patients with type 2 diabetes mellitus and heart failure with preserved ejection fraction.

Materials and Methods. The study included 80 patients with HFpEF and T2DM, with 40 patients in the empagliflozin group and 40 patients in the control group. Baseline characteristics, including age, gender, blood pressure, body mass index, and cardiac markers (HbA1c, NT-proBNP, Galectin-3, and sST2), were assessed. Changes in glycemic control and cardiac markers were analyzed after the treatment period.

Results. Baseline characteristics showed no significant differences between the two groups, indicating successful randomization. Post-treatment analysis revealed a numerical trend towards improved glycemic control in the empagliflozin group compared to the control group. Notably, empagliflozin treatment led to a significant reduction in NT-proBNP levels, indicating improved cardiac function and reduced cardiac stress. Furthermore, empagliflozin was associated with lower Galectin-3 and sST2 levels, suggesting potential benefits in mitigating cardiac fibrosis, remodeling, and inflammation.

Conclusions. Empagliflozin treatment in patients with HFpEF and T2DM have multifaceted implications beyond glycemic control. The observed reductions in NT-proBNP, Galectin-3, and sST2 levels suggest potential improvements in cardiac function, fibrosis, remodeling, and inflammatory processes. These findings highlight the potential of empagliflozin as a therapeutic option for managing HFpEF and T2DM, offering the potential for comprehensive cardiovascular benefits in this patient population.
State of the Hippocampus and Frontal Brain in Rats with Experimental Hypothyroidism
Authors: Lesiv Maryana , Yurakh Omelian
Published: October 2023

Introduction. Despite the fact that today patients with hypothyroidism manage to correct their hormonal profile, perfect control is not always achieved during the course of the disease. This was noted in a study of 22 people with hypothyroidism according to medical records for 8.24±0.76 years: the average TSH level was 7.14±2.37 mIU∕l, T4 was 23.01±4.38 pmol/l, although at the start of the study TSH was 3.72±0.76 mIU∕l and T4 was 13.8±1.96 pmol/l. Ultimately, this affected cognitive functions, including attention, speech and memory, despite the fact that cognitive impairment with drug compensation of hypothyroidism is considered reversible.

The results of a morphological study of the hippocampus and frontal lobe of the brain in rats with experimental hypothyroidism at an early stage can serve as a prototype for changes in the corresponding structures responsible for cognitive functions in individuals with hypothyroidism, even against the background of relative compensation with a long course of the disease.

Objective. To study morphology of the brain areas responsible for cognitive functions, in particular the hippocampus and anterior-frontal cortex in rats in the early stages of experimental hypothyroidism.

Materials and methods. The study included 12 white outbred sexually mature male rats. Hypothyroidism was modelled in 7 rats using the drug “Mercazolil” (“Zdorovye”, Ukraine). After 28 days, the animals underwent light-optical study of the histological structure of CA1, CA3 fields of the hippocampus, dentate gyrus and anterior-frontal cortex. Five animals were intact and, accordingly, served as controls.

Results. The light-optical examination revealed the sequence and depth of the violations: the most pronounced dystrophic changes with vacuolation of structures occur in the dentate gyrus; in the hippocampus itself, the CA1 field is the most vulnerable; lateralisation of hippocampal morphological changes with left-sided dominance was detected; minor morphological changes were detected in the anterior-frontal cortex. It is important that neuro-glial changes occur in parallel with vascular disorders.

Conclusions. Under the conditions of simulated hypothyroidism, changes occur in all studied brain components with their left-sided dominance, except for the anterior-frontal cortex.
Peculiarities of Arteriovenous Prosthesis Functioning in Patients on Hemodialysis
Authors: Semchenko Vladyslav , Popadyuk Oleh , Legun Oleh
Published: October 2023

Long-term and proper functioning of vascular access is necessary for renal replacement therapy in patients with chronic kidney disease (CKD). If it is impossible to form an arteriovenous fistula due to a pathologically changed structure of the vascular wall of peripheral arteries and veins, an arteriovenous prosthesis of various locations is implanted to form a permanent vascular access. However, the problem of long-term use of arteriovenous prostheses remains relevant, in particular, due to the prevalence of hemodynamic disorders, such as thrombosis, stenoses, and pseudoaneurysms.

The aim of the study was a retrospective analysis of hemodynamic disorders and peculiarities of the use of arteriovenous prostheses as permanent vascular access in patients undergoing hemodialysis therapy.

There were analyzed 586 medical records of inpatients and 103 discharge epicrisis of outpatients of the intensive nephrology department. Out of the 467 primary permanent vascular accesses formed for renal replacement therapy, 391 (83.72%) ones – were native arteriovenous fistulas (AVF) and 76 (16.27%) – were arteriovenous prostheses (AVP).

It was found that the increase in the frequency of initial uncorrected and corrected primary loss of vascular access for AVF is the greatest during the first year of use and amounts to 35.53% and 26.32% of cases, respectively. Instead, the greatest increase in secondary loss of patency is observed during the first six months of using prostheses, which corresponds to 10.53% of patients. It is worth paying attention to the problem of concomitant pathology, in particular diabetes mellitus, arterial hypertension, calcification disease, which directly affect the state of the vascular wall and the functioning effectiveness of the vascular access. The obtained results indicate the necessity to review and supplement the existing methods of prevention of hemodynamic disorders of AVF during the first 6-12 months of their use in order to improve the quality of patients’ lives.
Improvement of the Endodontic Treatment Efficiency of the Maxillary First Molars Using Differentiated Instrumental Preparation of the Apical Part and Additional Sealing of Root Canal Orifices
Authors: Kobryn Nataliya , Hereliuk Vitalii
Published: October 2023

Introduction. Endodontic treatment of maxillary first molars (MFMs) is very challenging due to the anatomical complexity of root canals which makes it difficult to do the proper cleaning, shaping, and obturation.

Aim was to study the effectiveness of a proposed endodontic treatment of maxillary first molars, compared to the traditional method, in patients with and without concomitant generalized periodontitis.

Methods. Endodontic treatment of 176 maxillary first molars was carried out according to the traditional method and proposed one, which included a differentiated approach to the instrumental preparation of the apical part of the root canal, and additional sealing of the root canals orifices using glass-ionomer cement. Obturation was conducted by lateral compaction of gutta-percha, combined with zinc-oxide-eugenol (ZOE) sealer and sealer based on epoxy resins. The effectiveness of endodontic treatment was evaluated based on the radiological comparison of the index, area of periapical destruction, and optical density of treated teeth roots immediately after, in 6 and 12 months.

Results. In 12 months after the endodontic treatment in the subgroups where the proposed technique was used, in patients with chronic apical periodontitis, better positive dynamics of the % increase in densitometric indicators, % increase of ​​periapical bone destruction, and the decrease of PAI were noted. The % increase of the ​​destruction area in the subgroup with the proposed treatment in combination with ZOE sealer was (79.21±2.41) %, that characterizes the decrease in the area from 14.03±0.7 mm2 to 2.65±0.26 mm2. It was established that the index of endodontic treatment effectiveness is significantly lower in patients with generalized periodontitis of 2nd degree, compared to patients with healthy periodontium(p<0.05).

Conclusions. It was established that the combination of the proposed method of treatment and ZOE sealer showed high effectiveness of endodontic treatment, due to the radiological picture in 12 months. It was found that there can be a possible negative effect of tooth mobility on the prognosis of endodontic treatment.

Published: October 2023

Ovarian granulosa cell tumours (OGCT) are non-epithelial neoplasms of the ovaries and belong to the group of granulosa-stromal tumours. The most likely source of these tumours’ development is granulosis of the primordial follicles of the ovary as a result of hormonal imbalance.

The aim of the study is to represent a clinical observation of acute intestinal obstruction caused by a giant ovarian granulosa cell macrofollicular tumour.

A woman, aged 52 years, medical history № 2579, was admitted to the surgical department of Communal Non-Profit Enterprise (CNPE) City Clinical Hospital (CCH) № 1 in Ivano-Frankivsk as an urgent patient with complaints of nausea, vomiting, delayed passage of flatus and defecation, general malaise, abdominal distention. During the laboratory and instrumental examination, a giant tumour of the abdominal cavity was revealed; it has led to the compression of internal organs and the development of small- and large-intestinal obstruction. The operation was performed: middle-median laparoscopy, removal of a giant cyst of the right ovary. Complete hysterectomy with appendages, drainage of the abdominal cavity were also performed.

  During the operation, a giant tumour with dimensions of 65x70x50 cm, of dense but elastic consistency, pale-pink in color, with multiple chambers of different diameters filled with cloudy, yellow liquid was revealed. The removed uterus with appendages and a large omentum were also given for pathological examination. Pathohistological examination results included: 15824-8- granulosa-cell ovarian tumour; 15815-7- uterus - plethora; 15818-20-ovary - white bodies, fallopian tube - chronic salpingitis; 15812-4- omentum - focal hemorrhages. The postoperative period was uneventful, the patient was referred to a gynecologist-oncologist for consultation and treatment.
Some Pathogenetic Aspects of Endocardial Endothelium Damage of Rats as a Result of Stress Effect Complicated by Hypercholesterolemia (original research)
Authors: Luchko Igor , Huranych Tetyana , Tuchak Oksana , Storozhuk Leonid
Published: October 2023

The endothelial dysfunction is a predictor of occurrence for many diseases of cardiovascular system and a key link in their pathogenesis, formation and progression of clinical manifestations. Despite the large number of experimental and clinical researches, separate links of pathogenesis of heart endothelial cell damage under stress and in case of its combination with hypercholesterolemia require the further examination. The aim of the work was to investigate the role of nitric oxide, prostaglandins and antioxidants in the pathogenesis of endocardial endothelium damage (by the content of free fatty acids in it and the number of exfoliated cells) as a result of emotional and pain stress and stress complicated by hypercholesterolemia. An electro-impulse model was used to reproduce the stress. Alimentary hypercholesterolemia was modeled by keeping animals on an atherogenic diet for 2 months. To establish the role of individual pathogenetic links in the mechanisms of endotheliocyte damage, animals were administered the following pharmacological drugs: L-arginine (a substrate for the synthesis of nitric oxide), a prostaglandin synthesis blocker indomethacin, and prostenon (a synthetic analog of prostaglandin E2, which has an antioxidant effect). The state of endocardial endothelium was examined by using the light microscopy, analyzing the smears-imprints from macropreparations of ventricles by counting the number of endothelial cells in them. The content of free fatty acids was determined by the radiochemical method. It was shown that L-arginine significantly limits the damaging effect of the studied pathogenic factors on endocardial endothelium, reducing the number of exfoliated cells. The use of prostenon gives a slight, statistically unreliable positive effect. The use of indomethacin increases the damage of endothelial cells, which indicates the cytoprotective effect of prostaglandins under stress. All three studied preparations have no significant effect on the metabolism of free fatty acids both in case of “pure” emotional and pain stress and under stress complicated by hypercholesterolemia. The hypercholesterolemia of alimentary origin significantly limits the cytoprotective effect of L-arginine and prostenon on endocardial endothelium under stress action. In relation to indomethacin, in this situation, an increase of cell desquamation is observed, which indicates a decrease of prostaglandins protective effect.

ChatGPT Interactive Medical Simulations for Early Clinical Education: Case Study
Authors: Scherr Riley , Halaseh Faris F , Spina Aidin , Andalib Saman , Rivera Ronald
Published: October 2023

Background

The transition to clinical clerkships can be difficult for medical students, as it requires the synthesis and application of preclinical information into diagnostic and therapeutic decisions. ChatGPT—a generative language model with many medical applications due to its creativity, memory, and accuracy—can help students in this transition.

Objective

This paper models ChatGPT 3.5’s ability to perform interactive clinical simulations and shows this tool’s benefit to medical education.

Methods

Simulation starting prompts were refined using ChatGPT 3.5 in Google Chrome. Starting prompts were selected based on assessment format, stepwise progression of simulation events and questions, free-response question type, responsiveness to user inputs, postscenario feedback, and medical accuracy of the feedback. The chosen scenarios were advanced cardiac life support and medical intensive care (for sepsis and pneumonia).

Results

Two starting prompts were chosen. Prompt 1 was developed through 3 test simulations and used successfully in 2 simulations. Prompt 2 was developed through 10 additional test simulations and used successfully in 1 simulation.

Conclusions

ChatGPT is capable of creating simulations for early clinical education. These simulations let students practice novel parts of the clinical curriculum, such as forming independent diagnostic and therapeutic impressions over an entire patient encounter. Furthermore, the simulations can adapt to user inputs in a way that replicates real life more accurately than premade question bank clinical vignettes. Finally, ChatGPT can create potentially unlimited free simulations with specific feedback, which increases access for medical students with lower socioeconomic status and underresourced medical schools. However, no tool is perfect, and ChatGPT is no exception; there are concerns about simulation accuracy and replicability that need to be addressed to further optimize ChatGPT’s performance as an educational resource.

Bioassay Method Development to Test Sitophilus oryzae Sensitivity against Phosphine
Authors: Harahap Nafsiyah Agustina , Witjaksono Witjaksono , Martono Edhi , Trisyono Y. Andi
Published: October 2023

Sitophilus oryzae is a cereal product pest found in warehouses. The presence of this pest negatively impacts the quality and quantity of stored rice. The common method used to control warehouse pests is fumigation. However, frequent use of insecticides will trigger resistance within target pest populations. This study aimed to develop a bioassay method based on the Food Agriculture Organization (FAO) protocols and modify bioassay protocols to determine S. oryzae susceptibility of populations collected from traditional markets across Yogyakarta. Field populations were collected from eight traditional markets in Yogyakarta (Lempuyangan Market [Kapanewon Danurejan], Kranggan Market [Kapanewon Jetis], Caturtunggal Market [Kapanewon Depok], Godean Market [Kapanewon Godean], Imogiri Market [Kapanewon Imogiri], Pleret Market [Kapanewon Pleret], Kasihan Market [Kapanewon Lendah], and Brosot Market [Kapanewon Galur]). The reference population was obtained from the Southeast Asian Regional Centre for Tropical Biology(SEAMEO BIOTROP). The bioassay was carried out following FAO protocols by using a glass jar fumigation chamber (volume 2 L) which was a modification of the desiccator of FAO recommended method number 16. This test used the lowest testable dose for this method: 0.01 × 10-2 mg/2L or 0.5 × 10-2 µg/L tested on 100 imagoes which were divided into five replications and obtained 100% mortality on the second day (48 hours). Results showed that the FAO fumigation chamber method could not be used in the test, so modifications were carried out to determine tested doses by changing the volume of the fumigation container. The test used three container volumes, including 20, 60, and 80 L. Result from 20 L container showed 82-100% mortality, 60 L containers showed 69-100% mortality, and 80 L containers showed 24-79% mortality. Results from 80 L container was suitable for the bioassay because it was able to test the lowest dose on reference insects. Eight doses ranging from 0.125 to 1.625 × 10-2 µg/L, and an untreated control were used to determine the LD50 of phosphine on each population. Insects were fumigated for 48 hours and then removed to observe mortality. The LD50 of the reference population was 0.27 × 10-2 µg/L while 0.29-0.54 × 10-2 µg/L for field populations. These findings indicate that S. oryzae populations collected from traditional markets in Yogyakarta were still susceptible to phosphine.

Published: October 2023

Rice (Oryza sativa) is an important staple crop for more than half of the world's population to fulfill required nutrients. The most important pest in rice crops is the field rat (Rattus argentiventer), which causes damage and significant yield losses during almost every growing season. One method of rat control is the Trap Barrier System (TBS) which consists of fences, mass/multiple live traps, and trap crops and was able to continuously catch rats during the growing season. The objectives of this study were to count rat captured in TBS during one planting season in fallow lands, identify attack source, and calculate rat damage intensity. The study was conducted on one hectare of rice field and number of rat caught were observed daily. Results showed that 4,580 rats were caught, consisting of 57% males and 43% females, with 94% adults and 6% juveniles. Average rat damage intensity was 15% and the highest number of rats caught were in trap 8, 9, and 10 which were located on the north side and had many suitable shelters for rats.
The Impact of Sino-Soviet Relations on the Evolution of China’s Foreign Policy (1945-1956)
Authors: Yang Li
Published: October 2023

“Sino-Soviet relations were pivotal in the diplomatic history of the PRC after its establishment. On one hand, the CCP received significant economic assistance and political support. However, like any alliance, it revealed conflicts between collective ideology and national interests. These tensions even drew the PRC into Korean wars that might have otherwise been avoided. Concurrently, the PRC developed a self-reliant and peaceful diplomatic policy soon after forming the Sino-Soviet alliance. The mutual relations between the CCP and CPSU closely influenced the emerging PRC’s foreign policy.This study aims to research how these ties between the CCP and CPSU impacted the evolution of the PRC’s foreign policy from 1945 to 1956. Such research is essential for understanding the formation of the PRC’s foreign policy through the lens of inter-party diplomacy, explaining the enduring principle of an independent foreign policy focused on peace. This study employs historical research methods and archive analysis, drawing from declassified historical archives and primary and secondary sources, while critically analysing international relations theories based on historical facts.The findings reveal that the USSR’s primary concern was its national interest, while the CPC idealized it as a revolutionary party. As a result, the CCP developed an independent and self-reliant diplomatic approach based on different foundations.
Empathic Communication and Artistic Healing Role of Local Music in Xiamen City under Major Social Events
Authors: Du Ao , Guo Xiaohua
Published: October 2023

From local to global, from individual to universal, from singularity to plurality, music not only promotes the deep integration and dissemination of urban culture, giving birth to the theoretical perspective of “music studies”, but also becomes an important symbol and weathervane of a city’s cultural trend. Whether it is a metropolis such as London, Paris or Beijing, or an art city that focuses on the city’s on-the-ground music creation or identity, music is closely connected to the urban cultural space. At the same time, music is also a “holistic effect art”, a language of cultural globalisation. This study will be based on the creation and dissemination of Xiamen’s urban music works under major social issues, taking aesthetic function and artistic healing as the entry point, combining with the case study of Xiamen’s urban in situ music works to explore the current situation of the creation and dissemination of its works, elucidating the social value and artistic healing function of the city’s songs, and rethinking and exploring the relationship between literary and artistic works and the harmonious development of the human society, and the role of the city’s brand shaping and influence on city branding. This research will mainly focus on the literature research method and case study method, using the Internet and electronic resource databases to review the literature, understand the knowledge related to music and art, clarify the development of urban local music and the current status of research, and obtain relevant research information, so as to provide ideas and references for the project research. To analyse the data of urban local music creation and dissemination with appropriate statistical and analytical methods, in order to maximise the function of the data and play a role in the data. Take urban local music as a typical case, investigate it, and give solution ideas and programmes, and look forward to the direction of creation and dissemination of contemporary literary works of urban local music under major social events.

Published: October 2023

В настоящей работе представлены результаты по изучению элементного состава осадков, в том числе воскообразных, из высоковольтного маслонаполненного оборудования, в котором трансформаторное масло эксплуатировалось более 30 лет. С помощью метода масс-спектрометрии с индуктивно связанной плазмой в составе осадков из трансформаторов и высоковольтных вводов обнаружены такие металлы, как Cu, Fe, Zn, Ni, Cd, Co, Pb, Cr, Mn. При этом в осадках из силовых трансформаторов в наибольшем количестве содержится железо (Fe) >> медь (Cu) > цинк (Zn), а в осадках из высоковольтных маслонаполненных вводов медь (Cu) ≈ железо (Fe) >> цинк (Zn). Проведены специальные опыты, подтверждающие механизм образования металлоорганических соединений в масле, в частности, образование солей стеариновой кислоты. Опыты заключались в приготовлении модельных растворов, приближенных к составу трансформаторного масла и состоящих из гексана, ионола, бутилстеарата и стеариновой кислоты; добавлении к ним порошкообразных металлов (Cu, Sn, Zn, Fe, Al) и их оксидов (CuO, SnO, ZnO, Fe2O3, Al2O3); выдерживании смеси в течение 1–20 ч и последующем определении концентрации компонентов. Исследования показали, что соли карбоновых кислот в органической матрице образуются при взаимодействии карбоновой кислоты с металлами (Zn, Fe, Al) или их оксидными пленками (ZnO, Fe2O3, Al2O3). С менее активными металлами (Cu и Sn), а также с их оксидами (CuO и SnO) расходование стеариновой кислоты не наблюдалось, то есть реакция между кислотой и добавками (Cu, Sn, CuO, SnO) не протекает, это указывает на то, что медь и олово в масляных осадках связаны с другими анионами, преимущественно с сульфид-­ионом.

Authors: Concheiro San Vicente Luciano
Published: October 2023

Este libro explica algunas de las propuestas hechas desde el marxismo neotropical sobre los modos de producción en América Latina. No es una historia general del tema. Lo que se busca es explorar algunos de los debates teóricos y políticos que sucedieron en la región a partir de mediados de la década de los sesentas a partir de una serie de casos concretos y poco estudiados: la caracterización de las sociedades americanas precoloniales, la necesidad de pensar categorías analíticas específicas para la historia y realidad latinoamericanas, la condición feudal o capitalista de América Latina, la proletarización del campesinado, el rol político del campesino, la relación entre el capitalismo y la crisis medioambiental.

Objectives The aim of this study was to verify the efficacy of a mentoring program designed for novice school counseling teachers through the development and implementation of a mentoring program aimed at enhancing their their competencies.
Methods To assess the effectiveness of the mentoring program for novice school counseling teachers, qualitative content analyses (QCA) and nonparametric methods were employed.
Results The results of QCA indicate that mentors reported experiencing professional improvement and enhanced competence. The mentoring program ignited a desire for growth and broadened the scope of school counseling for mentors. Similarly, mentees expressed that their participation in the mentoring program played a pivotal role in adapting to school counseling, improving professionally as school counseling teachers, and shaping their iden-tity in this role. Furthermore, the levels of school counseling teacher’s competency were measured before and af-ter the program. Nonparametric analyses were conducted using SPSS 23.0. The differences between pre-scores and post-scores for total competency, educational competency, and administrative competency were found to be statistically significant.
Conclusions This study has implications as it developed and implemented a mentoring program based on the needs of school counseling teachers. It also verified the program’s effectiveness in enhancing the competency of school counseling teachers. The mentoring program can contribute to the field of school counseling by bolster-ing school counseling teachers’ competency.

Published: October 2023

Objectives This study aims to examine my experiences as a researcher and an low experienced special class teacher teaching deaf-blind students and to determine practical knowledge built through this experience.
Methods I used autoethnography to examine my experiences as a researcher to achieve the purpose of this study. Autoethnography is a qualitative research method that involves critically narrating one's reflective stories about their personal experiences within a social context, with the aim of facilitating a theoretical understanding of one's life. In this context, as the researcher, ‘I’ sought to describe the ‘experiences of an low experienced special education teacher’ assigned to the social and cultural environment of a ‘special class with deaf-blindness stu-dents’ from a reflective and self-reflective perspective.
Results The results of this study are as follows. First, I feared educating students with deaf-blindness, but ‘knowledge of the milieu of teaching’ was built by identifying the characteristics of deaf-blind students from mul-tiple aspects. Second, ‘knowledge of the curriculum and subjects’ was built by process of designed, conducted, and evaluated classes of educating these students. Third, ‘personal knowledge as a teacher’ was built by cooper-ating with teachers and parents, communicating with deaf-blind students and those without disabilities, and growing into an expert in educating deaf-blind students.
Conclusions The results provide the necessary pointers for improving the adaptability of low experienced special education teachers.
