Published: April 2024

Abstract. Kresna Hotel Wonosobo is an old hotel located in Wonosobo city. Founded in 1917 under the name Grand Hotel Dieng and run by a Dutchman named JW Muthert. In modern times like today, many hotels have collaborated with Online Travel Agents (OTA). This is because OTA can help hotels on the marketing side in a wider scope. Kresna Hotel Wonosobo has collaborated with OTA since 2016. But so far, there has never been an application that can assist the hotel in evaluating, monitoring and assessing OTA activities. So the creation of a dashboard to evaluate, monitor, and assess OTA activities at Kresna Hotel Wonosobo is needed. The dashboard is made using the System Development Life Cycle (SLDC) waterfall model and the data processing process uses the nine step design method. This dashboard is focused on three OTAs, namely Traveloka, AGODA, and Tiket.com. The dashboard has succeeded in displaying all the data needed on the target Key Performance Indicators provided by the hotel. By creating a dashboard and adding a web admin, it is hoped that Kresna Hotel Wonosobo can continue to use it for OTA monitoring in the future.

HIGHER INSTITUTION STUDENTS’ CHALLENGES IN WRITING JOURNAL ARTICLES: CHARACTERISTICS AND PROPOSED SOLUTIONS
Authors: Sahan Anselmus , Saridewi Maria P , Wabang Rince J , Adrianus Nabung
Published: April 2024

This qualitative study aimed to identify the challenges faced by final semester students in Indonesian tertiary institutions when writing journal articles, and propose potential solutions to these challenges. The study analyzed 32 articles published in Timor University e-journals, selected purposively from 16 study programs. Results showed that the majority of articles (59%) scored 75, indicating a need for improvement. The most significant challenges faced by students were related to introduction and method (13%), results (13%), and discussion (13%). These findings were consistent with the results of a questionnaire analysis, which identified method and abstract (22%), discussion (30%), and all parts (26%) as problematic areas for students. To address these issues, the study proposes a formal mandate requiring all lecturers to accompany their students in writing journal articles. This mandate would provide students with necessary support and guidance to improve their writing skills and meet the acceptable journal template requirements. The proposed solutions aim to alleviate the academic burden faced by thesis advisors, editors, and reviewers, while also improving the quality of articles produced by students.
EXPLORING THE IMPACT OF CRITICAL DISCOURSE ANALYSIS (CDA) ON ENHANCING 21ST CENTURY TEACHERS’ CRITICAL READING ABILITIES
Authors: Sari Cut Purnama , Santoso Anang , Roekhan Roekhan , Susanto Gatut
Published: April 2024

This research aims to investigate the relationship between critical reading abilities and critical discourse analysis (CDA) competencies among future 21st century educators, emphasizing the critical necessity for these educators to possess such skills in today's demanding educational landscape. A sample of 70 prospective teachers was analyzed to determine the interconnection between their abilities in critical reading abilities and CDA, with an exploration into how one skill may influence the other. Additionally, the study examines the role of cognitive style—specifically, field-independent and field-dependent thinking—as a moderating factor in this relationship. Findings indicate a significant positive impact of CDA capabilities on critical reading abilities, suggesting that proficiency in analyzing discourse critically enhances one's ability to read with a critical eye. Furthermore, the study reveals no significant difference in CDA and critical reading abilities between participants categorized as field-independent thinkers versus those identified as field-dependent thinkers. These outcomes highlight the need for further research to explore additional factors that may affect the development of critical reading and discourse analysis skills. The study concludes with a call for educational strategies that integrate both critical reading and CDA competencies, considering the varied cognitive styles of learners.

Instagram is one of the mobile apps to assist language learning. The most widely used social networking platform globally right now is Instagram. This study aimed to investigate the perspective of university students on using Instagram reels as mobile-assisted language learning to improve speaking skills whether they had a negative or positive perception of it. This study utilized a descriptive qualitative approach and the research instrument used a closed and open-ended questionnaire with 66 respondents from the first until the seventh semester. This study found that the majority of students have a positive perception of using Instagram reels in speaking skills. Students believe that this tool is comfortable and fun to develop a new atmosphere in learning to speak, it also increases their motivation because Instagram reels provide interesting content for improving their speaking skills, they can find many Instagram accounts that post more about English lessons with short duration even though students sometimes get a distract cause of random video but they already know their own goals to practice consistently every day and everywhere. Through this tool, students gain a lot of vocabulary from the video, quotes, caption, or comment section that is very helpful for them to improve their speaking performance especially when they are engaged in communication with other people both inside or outside classroom practice.

Authors:   Institute of Philology of the SB RAS, Novosibirsk, Russian Federation, Myasnikova S.A. ,   Omsk State University of F. M. Dostoevsky, Omsk, Russian Federation
Published: April 2024

The article focuses on analyzing archival materials from Omsk that pertain to the summer period of the Belarusian resettlement calendar. The analysis covers various sources, including the folklore and ethnographic funds of Omsk, such as the Omsk State Pedagogical University Folklore Archive, the regional Fund of Folklore and Ethnographic Materials of the State Folk Art Center, the Museum of Archaeology and Ethnography of Omsk State University, and personal archives of traditional culture researchers and regional publications. The author meticulously reviewed and considered all the available records, encompassing the period from 1951 to the most recent expedition materials of 2010–2021. The specific regions in the Omsk Priirtyshye, where recording and living traditions are found, have been determined. Additionally, the areas where Belarusian settlers came from (Chernigov, Vitebsk, Mogilev, Minsk, and Vilna provinces) have also been identified. The study presents numerical indicators of the documented Priirtysh fixations, including seasonally scheduled summer customs and songs (Trinity, Ivan Kupala, and Petrov Day), occasional rituals, mythological tales (featuring fortune-tellers and witches during Ivan Kupala, the legend of the fern flower, mermaids, beliefs about the cuckoo, and summer divination). The Omsk archival material is evaluated in terms of its content quality, representativeness, and potential for in-depth analysis using textual, musical-typological, dialectological, and areal criteria. Previously unreleased archival texts that illustrate the described tradition are being introduced into scholarly circulation. This article is an introduction to a series of extensive studies on the summer calendar of Belarus, which were documented in the Omsk Priirtyshye region.
Tuvan “Song of the Caravan Leaders”: from Mongolian origins to the present day
Authors:   Tuva Institute for Humanitarian and Applied Socio-Economic Research under the Government of the Republic of Tyva, Kysyl, Russian Federation, Donorova U.O.
Published: April 2024

The article explores the origins and evolution of the Tuvan folk song “Beezhin.” During the years of the Tuvan People’s Republic (1921–1944), the song under study was borrowed from the Mongolian original, the song-play “Sumuyaa noyon.” Since the 1980s until now, the song “Beezhin” has been serving as a folk song in Tuva. Of great interest in modern culture are the ways of adaptation, development in the folklore environment and transformation of this song in the author’s songwriting of the Honored Artist of the Russian Federation, People’s khoomeizhi Tuva Kaigal-ool Khovalyg. This research was conducted on the basis of valuable archival materials from the Collection of Manuscripts and Rare Documents of the Institute of Oriental Manuscripts of the Russian Academy of Sciences (St. Petersburg), the Scientific Archive of the Tuvan Institute for the Humanities and Applied Social and Economic Studies, including some samples of the text presented in the author’s translation from Tuvan into Russian.
Review of the dissertation “Reconstruction of the linguistic landscape of Western Siberia (a case study of the Samoyedic languages),” submitted by A. Y. Urmanchieva for the degree of Doctor of Philology
Authors:   ", Tuchkova N.A. ,   Museum of Nature and Man",   , Khanty-Mansiysk, Russia
Published: April 2024

The dissertation “Reconstruction of the linguistic landscape of Western Siberia (a case study of Samoyedic languages)” written by A. Y. Urmanchieva focuses on tracing the Samoyedic group language history. The period under study starts after the collapse of the Proto‒Samoyedic language and ends with the resettlement of the native speakers of Samoyedic languages as recorded in historical documents (16th–18th centuries). The work substantiates the preservation of the links between the Proto-Samoyedic and the Proto-Ob-Ugric languages after their collapse, with separate contacts between the Mansi and South Samoyedic languages. The author confirms the original boundary between the Mansi and Khanty languages, from west to east, and shows that Proto-Mansi was widespread in more southern territories, while Proto-Khanty was prevalent to the north (and not to the east) of the lower Ob basin. Additionally, the author confirms that Matorsky belongs to the Northern Samoyed subgroup. The analysis of separate parallels allowed the author to establish the early contacts between Nganasan, Selkup, and Kamassian and later between Nganasan and common Enets languages. Given these findings, the following successive linguistic landscapes of Western Siberia have been reconstructed. Initially, the migration of the forebears of Samoyedic language speakers moved towards the Ob basin from their original homeland, with a settlement pattern along the Ob tributaries determined by taiga fishing culture. Later, the expansion of the Khants towards the east along the middle Ob River disrupted the previously established pattern, leading to a break in the linguistic continuity of the Samoyed area.
Determinative polypredicative constructions in the Khakass language
Authors:   N. F. Katanov Khakass State University, Abakan, Russia, Chugunekova A.N.
Published: April 2024

In the Khakass language, modifying constructions tend to incorporate nonfinite forms as dependent predicates. The dependent modifier precedes the main part of the whole phrase. Prototypical modifying constructions are represented by models with relativization of the core units of the modifying system: subject, object, localizer, and possessor. The subject relativization models are characterized by the absence of the subject position in the dependent predicative unit (DPU). The object, localizer, or possessor relativization models feature the presence of the subject position of the DPU. The dependent predicate is represented by nonfinite forms of the present (on =chatkhan), present-future (on =han), past (on =gan), and future (on =ar). Khakass modifying constructions are formed from analytical bifinite constructions where conjunctive words connect the main and dependent parts. Such sentences, commonly found in translated, poetic, and paremic texts, are rarely used in the spoken language. In terms of semantics, the structures under study can be divided into explanatory-modifying, restrictive-modifying, and circumstantial-modifying phrases. The explanatorymodifying phrases follow three models, with the connection between the noun being modified and the modifying DPU performed by the adverbial participle of the verb tip combined with the words being modified, by the causative, and by the conjunctionless connection. In the restrictive-modifying phrases, the nature of semantic relations between the DPU and the main predicative unit (MPU) is strongly connected with the noun being defined. The circumstantial-modifying phrases are based mainly on the models of Russian compound sentences with a modifying clause, with MPU structurally occupying always a prepositive position.
Structural and functional-semantic classification of Koryak polypredicative constructions with the clause linkage marker tite ‘when’
Authors:   Institute of Philology, SB RAS, Novosibirsk, Russian Federation, Tarasevich D.V.
Published: April 2024

The paper presents structural and functional-semantic classifications of Koryak polypredicative constructions with the clause linkage marker tite ‘when’. These are syntactic units prototypically comprising two clauses linked by the word tite and encoding the relation between the events expressed by these predicative units. Given the endangered status of the Koryak language, it seems imperative to document its grammar. Furthermore, the Koryak syntax is particularly intriguing from a typological perspective due to its polysynthetic nature and extensive use of non-finite verb forms with nominal case affixes directly attached to the verb stem. This study employed the methodology developed by the scholars of the Institute of Philology of the SB RAS. The classifications were developed by analyzing the constructions concerned in the texts of the three native speakers. The three main parameters of the analysis were the forms used as predicates of clauses, the morphological nature of the clause linkage markers, and the semantic relation between the events. In terms of the morphology of clause linkage markers, the constructions can be categorized into proper analytic and analyticsynthetic types, while the forms of the predicates determine whether they are bi-finite, monofinite, or bi-nonfinite. The non-finite verb form system exclusively employs negative, locative, dative converbs, and converbs of simultaneity. When considering its functional aspects, the author regards tite as a versatile marker of clause linkage, encompassing temporal-conditional and complement constructions. Posteriority, partial simultaneity, and reality condition are among the most prevalent semantic types. Ultimately, this study emphasizes the correlations between structure and meaning.
The image of earth spirit in the olonkho epic. Part 3: The path of evolution
Authors:   North-Eastern Federal University named after M. K. Ammosov, Yakutsk, Russian Federation, Satanar M.T.
Published: April 2024

The article focuses on analyzing how the image of the spirit-mistress of the earth has evolved over time. The study has revealed that the image was created by combining elements from various historical periods. The oldest stratum leads us to the image of the ancient Stone Age civilization, with its polyfunctional and multicomponent nature reflecting the syncretic worldview of ancient people who endowed it with astral, vegetative, and chthonic features. The Neolithic image of perception is associated with the first “offshoots” of functions from a single prototype. Subsequently, genetically related images of the spirits of forest, hunting, vegetative forces, fire, childbearing, and cattle litter appeared. A higher level of abstraction was characterized by the images of wisdom and mind, the creative principle, and the thunderer. The image under study demonstrates the stability of its function as a patronage of the fruit-bearing forces of nature, dating back to ancient times. During the Bronze Age, the prototype was enriched with the new idea of the reincarnation cycle of the human soul and the pathos of immortality. The patriarchy promoted the emergence of male images of spirits-masters of the earth later to be assigned the role of innovative “cultural creations” in the bosom of the earth. The final shape of the anthropomorphic image of the mistress of the earth was formed only in the early twentieth century due to the widespread collectivization in the USSR.

Published: April 2024

This article summarizes the materials collected and published by the authors during their field research in Buryatia on the practice of the collective prayer of lay Buddhists, referred to as sangaril. It was not until the twentieth century that researchers began studying this phenomenon of lay Buddhists. Among the most prominent studies are the works of S. G. Zhambalova and D. S. Zhamsueva. The examination of these works and some earlier sources has enabled the authors of this article to present a meticulous account of the history surrounding the introduction of sangaril during the early stages of Soviet power. A comprehensive description covers the timeline, implementation process, participant prerequisites, and religious artifacts associated with the ritual. The structure of three sangarils recorded in the villages of Ushkhaita and Kizhinga of the Kizhinga district and in the Khorinsk settlement of the Khorinsk district of the Republic of Buryatia is characterized. The variation in the sequence of sections of the ritual is discussed, with a focus on the normative, recurrent in different villages, and mobile ones. The correlation between Tibetan, Mongolian, and Buryat sacred texts is discussed. The analysis covers the musical component of the ritual, including the recitative reading of mani prayers alternating with the performance of magtaals (glorifications to Buddhist shrines sung on typical song tunes). The Buryat text of one magtaal is provided with a Russian translation and comments. The conclusion emphasizes the importance of sangaril in preserving the cultural values and ethnic identity of the Buryat people.

The current level of performance of piston compressors, characterized by the delivery coefficient, is at the level of 0,7. Advanced designs have higher rates, reaching values of 0,8...0,85. However, the negative effect of dead volume prevents the performance level of, for example, screw compressors from being achieved. Therefore, reducing the influence of dead volume on productivity can be considered the main task in improving modern piston machines. The presented work proposes a solution to eliminate the influence of the most significant component of the dead volume — linear space. As experimental studies have shown, the use of elastic discs mounted on the piston will virtually eliminate linear dead volume, ensure operational safety and increase the flow rate to 14 %.

This article is devoted to the study of thermal conductivity of nanofluid. A nanofluid is a liquid in which nanometer-sized solid particles are dispersed. These particles are called nanoparticles. Nanofluids have new promising thermophysical properties compared to conventional heat transfer fluids. Thermal conductivity is one of the main thermophysical properties of a liquid. Thermal conductivity is of great importance in processes where heat transfer and fluid flow occur. The article presents well-known theoretical models for determining the thermal conductivity of nanofluid. A brief description of these models is given. Some experimental work on determining the thermal conductivity of various nanofluids is considered. A computational study of the effect of aluminum oxide (Al2O3) and silicon dioxide (SiO2) nanoparticles on the change in thermal conductivity of a nanofluid has been performed. A comparative analysis of known computational models and experimental data is carried out. The accuracy of the calculated models is determined by determining the thermal conductivity of the nanofluid.

In the course of work on the energy perfection of thermal control systems for spacecraft with a twophase circuit, the issue of partial regeneration of thermal energy into electrical energy in a low-speed turbogenerator is considered, part of the design work requires computational modeling during the transport of swirling flows in the axial direction from the external input to the input plane into the impeller, which determines the need for theoretical and experimental elaboration of the problem. The paper considers transformations of equations for changing the amount of fluid motion in boundary conditions of an axial annular channel with fixed cylindrical surfaces. Assuming the symmetry axis of the flows using the integral form of writing the continuity equation, the relations are obtained in the form of two differential equations with expressed derivatives along the channel axis for the total pressure p* and the circumferential velocity constant Cu = UR (const — at the integration step). The equation forms the basis of the algorithm of integration in finite differences supplemented by a system of service equations describing the friction stress, thermodynamic parameters, etc. Test calculations are carried out using real parameters, the results are analyzed.

The analysis of thermal performance of radiation life support system based on experimental data
Authors:   Omsk State Technical University, Karagusov V. I. , Zinovieva A. V. ,   Omsk State Technical University
Published: April 2024

Solar energy is considered a renewable, most environmentally friendly and carbon-free form of energy. Solar collectors are one of the implementations of radiation life support systems. Their development requires a fairly large amount of initial data, such as the parameters of the premises, the required temperature, volume, thermal insulation of walls, floors and ceilings, the design of windows and doors, orientation to the cardinal points, the angles of inclination of the roof slopes, etc. The next group of factors is related to the location object, latitude, altitude above sea level, distance to large bodies of water, wind rose, etc. The third group is related to the weather itself: precipitation, cloudiness, outside air temperature, etc., a significant part of them, such as fog, haze, dew, shadow from each cloud affects the amount of insolation and all this cannot be taken into account in advance. The use of weather archives does not allow us to fully determine the specific thermal performance of solar collectors, since neither the average nor the current insolation is reflected in the archives. Without knowing the amount of real insolation and heat losses on the solar collector, it is impossible to determine the thermal performance of the radiation life support system per day, month, season or year. This paper discusses experimental and computational studies of the radiation life support system carried out in 2018–2022.

Published: April 2024

Ilota Nanasi Au-Ag deposit located in the western flank of the Gn. Baganite, a part rhyodacite dome in Gn. Pani district, Gorontalo Province, where the extensive exploration programs were carried out by PT Gorontalo Sejahtera Mining (a subsidiary of PT J Resources Nusantara) from 2012 – 2020.  As the result, a total of 72.7 Mt @ 0.98 g/t Au and 0.85 g/t Ag (2.3 Moz Au and 2.6 Moz Ag) mineral resource was delineated in 2019. This paper mainly aimed to the petrogenesis association of granitoid basement and rhyodacite unit as the host rock in the Ilota Nanasi gold deposit.
The geology of Ilota Nanasi is overlain by Late Miocene granodiorite, andesite and diorite basement, Pliocene volcanic complex predominantly dacite – rhyodacite, tuff, breccia, and quaternary deposit as alluvial and surface breccia. Hydrothermal alteration and gold – silver mineralization centered in the porphyritic rhyodacite host rocks where the intense silicification forming a zone around the hydrothermal crackle breccia unit and/or high-density quartz vein, veinlets and stockworks. Mineralization in Ilota Nanasi is interpreted as a low sulfidation epithermal system dominated by a large volume of hydrothermal crackle breccia, intense quartz veining, veinlets, and high-density fracturing.
A combined analytical result of petrography and whole-rock geochemistry has been used to assess the petrogenetic association of the rhyodacite and granitoid basement in the Ilota Nanasi. The result of the AFM diagram plot shows sample trends in calc-alkaline magma field. In contrast, the SiO2 – K2O plot distributed in two trends: the older unit was associated with high-K calc-alkaline and the shoshonite series for the younger unit. The changing of magma series is considered as product of crystallization differentiation of evolved parental magma or derived from the melting of mantle material after the mantle or lower crustal was metasomatized during a former episode of subduction.

Background: Ureteropelvic junction obstruction” is defined as an anatomical abnormality that results in a functionally significant impairment of urinary transport from the renal pelvis to the ureter. Congenital UPJ obstruction results due to the presence of an aperistaltic segment of the ureter. Objective: To determine the efficacy of Open Anderson-Hynes pyeloplasty in unilateral congenital UPJO in terms of GFR Materials and Methods: This descriptive study of 139 patients of paediatric age group was conducted in the department of urology, Institute of Kidney Diseases, Peshawar from 24 July, 2019 to 24 July 2020. Patients with UPJO were operated. Efficacy of the procedure noted in term of GFR. Follow up ultrasound followed by nuclear scan was done after 2 months. Results: Out of 139 patients, 60(43.16%) were of age 5-10yrs and 79(56.83%) i.e. the majority were 11-15 yrs with mean and SDs of 11±2.37. The overall complication rate was 36.69%. The efficacy in terms of GFR improvement OR at least prevention of deterioration of renal function was recorded in 115 (82.73%) patients while 24 (17.26%) showed no efficacy Conclusion: Anderson-Hynes pyeloplasty is an effective procedure in terms of renal function improvement or to prevent GFR deterioration at the preoperative level in comparison to those not operated with gradual reduction in GFR.

Objectives: To elucidate antibody responses to COVID-19 (coronavirus disease 2019) vaccination among patients with Prostate cancer (Pca), group comparisons between patients with Pca and healthy controls were conducted at several times points after COVID-19 vaccination. Methods: Blood samples from 19 consecutive patients and 12 healthy controls were prospectively collected before first vaccination, and at 1, 3, and 6 months after first vaccination. BNT 162b2 (Pfizer/BioNTech) vaccines were administered for all patients with Pca. Antibody titers were determined by enzyme-linked immunosorbent assay using recombinant protein of the SARSCoV- 2 spike-protein receptor-binding domain as an antigen. Results: Mean age was significantly higher for patients (73.6±9.7 years) than for controls (63.2±3.4 years; P<0.01). Mean initial PSA for the overall cohort was 330±615 ng/mL. Ten patients had localized Pca and 9 patients had metastatic Pca. ADT was administered for the 84% (16/19) patients. Treatment with ADT and/or Androgen Receptor-Axis-Targeted (ARAT) agent had been continuously performed in 68% (13/19) patients since the first vaccination. After the first vaccination, antibody titer was significantly increased at 1 month after vaccination and then gradually declined over time in each group. Regarding the comparison between the two groups, mean antibody titer was not significantly different in patients during the observational period. Conclusions: This is a first report from an Eastern country to find that immunological response to first COVID-19 vaccination was equivalent in patients with Pca compared with healthy controls.

Purpose: To share our experience of neurogenic bowel and bladder management by creating Malone Antegrade Continent Enema (MACE) procedure and Continent Urinary Diversion (Mitrofanoff VQZ technique) at the same time by using split appendix. Material and Methods: Between July 2017 and December 2021, 30 patients; 5 to 15 years old (mean 9.54±2.65 years) underwent VQZ Mitrofanoff and MACE using split appendix with or without bladder augmentation forneurogenic bladder and bowel management secondary to myelomeningocele. Proximal part of appendix was used for MACE by taking 3 antireflux stitches by wrapping seromuscular layer of cecum around base of appendix whereas distal part of appendix is used for Mitrofanoff creating VQZ stoma. The average length of appendix taken was 9.5 cm (8-12 cm). Results: All the patients were kept clean and dry throughout and were followed up for an average of 15 months (12 to 30 months). Only one patient was reported with MACE stoma stenosis because she lost to follow up and didn’t use the stoma for a year, stoma revision was performed on her. Procedure time is also reduced in split appendix MACE and Mitrofanoff as compared to if monti tube or cecal flap is reconstructed for MACE. Conclusion: MACE and Mitrofanoff with or without bladder augmentation are very invaluable procedures for the management of neurogenic bowel and bladder. Split appendix is an ideal channel for both Mitrofanoff and MACE.

Background: About 2-5% of adult testicular tumors are classified as sex cord/stromal tumors, which are an uncommon group of tumors of the testis. Occasionally, a small percentage of Sex Cord/stromal Testis Tumors (SCST) that are primarily composed of spindle cells seem to be unclassifiable. There are about six cases reported where spindle cells predominate, four of which are consisting purely of spindle cells. At the morphologic level, a striking resemblance to a fibroma has raised the notion of a possible fibrothecoma, but this is not supported by the immunohistochemistry, and the features are consistent with an unclassified sex cord/stromal tumor with a “pure” spindle cell component. Description: A 45-year-old man with a firm mass in the lower pole of the left testis for 3 years. The patient had no comorbidities and no features of endocrinopathies. All blood tests were normal. The ultrasound showed a solitary hypoechoic mass with increased blood flow by Doppler scan. A well-circumscribed tumor measuring 30mmx 15mm with no discernible capsule was identified macroscopically. Microscopy showed a well-circumscribed spindle cell lesion with no necrosis, cytological atypia, or mitoses. The tumor cells appeared spindled with eosinophilic cytoplasm, vesicular nuclei, and occasional nucleoli. No nuclear grooves were noted in the tumour cells. No vascular invasion was present. Actin, calretinin, CD99, S100, and inhibin were positively immunoreactive. Conclusion: The findings were consistent with an Unclassified pure spindle SCST, a rare tumor with a benign course that must be distinguished from several spindle cell neoplasms. There are no biochemical markers for the diagnosis of this tumor, thus requiring meticulous clinical examination, especially if it is small in size. We report a case of “pure spindle cell sex cord stromal tumour of the testis in a 45 years old man in which the histomorphological as well as the immunohistochemical features are consistent with the diagnosis of unclassified sex cord/stromal testis tumor with “pure” spindle cell component.

The study was conducted from November 2019 to April 2020 dairy cows in Dembi dolo town and Sayo district to assess the major observed health problem associated risk factors. The total of 475 dairy cows was included in the current observational study. From this selected dairy cows of 475; 201 in Sayo District and 274 in Dembi dolo town were examined for different health problems. Observational study was implemented by conducting regular visit during the study period with the interval of once per three weeks. Accordingly, Dermathophilosis (25.1%), mange mites (18.3%), tick infestation (30.1), lice infestation (20.2), retained fetal membrane (3.1), dystocia (2.8) as common reproductive problem of dairy cows. Infectious disease like clinical mastitis (5.9%), black leg (1.9%), lumpy skin disease (0.63%), foot and mouth disease (0.84) were also recorded. The result obtained from observational study showed that these major health problems hinder success of dairy cows operation and future expansion. Therefore further studies should be preceded to develop a control and prevention methods to improve the productivity of the sector.
