Magnitude of refractive errors in children in tertiary care hospital of western Nepal
Authors: Godar Srijana Thapa
Published: October 2020

Background: Refractive error is one of the most common causes of the visual impairment and second leading cause of treatable blindness. The objective of the study was to determine the mag­nitude of refractive errors in children.

Methods: This was a hospital based cross-sectional study conducted on 254 children attending Ophthalmology OPD of Manipal Teaching Hospital, Pokhara. The children whose visual acuity was worse than 6/6 but improved with pinhole were included in this study. Vision test, retinoscopy and subjective refraction was done in all subjects and cycloplegic refraction was done when needed. Statistical analysis was carried out using Epi-info version 7.

Results: The commonest type of refractive error was astigmatism (46.06%) followed by myopia (42.31%). Majority of children had low grade of refractive errors (46.85%). Among the children, “with the rule astigmatism” was maximum (27.56%). Majority of children were in the age between 11 to 15 years (77.95%). The refractive error was seen more in female (63.78%). Among the chil­dren of refractive errors, 29.13% had family history, 33.46% had given the history of wearing spec­tacles and 10.24% children had amblyopia. There was statistically significant association between refractive errors and age groups, history of wearing spectacles, amblyopia and grading of refractive errors. However, there was no statistically significant association of refractive error with gender, residence and family history.

Conclusions: Astigmatism was the common type of refractive error followed by myopia. This study emphasizes the importance of detection of refractive error in children.

Published: October 2020

Background: Trans-urethral resection of bladder tumor is an essential diagnostic tool as well as effective treatment modality for non-muscle invasive bladder cancer. We aimed to evaluate the recurrence and progression of the non-muscle invasive bladder cancer in Nepalese patients.

Methods: This was a retrospective study of 43 patients with non-muscle invasive bladder cancer, who underwent trans-urethral resection of bladder tumour followed by adjuvant intravesical instilla­tion of chemo or immunotherapy between January, 2013 to December, 2018. Patients were divided into low, intermediate and high-risk groups according to the clinical and pathological factors used by the European Organization for Research and Treatment of Cancer scoring system. Outcomes were calculated in terms of recurrence and progression in each group.

Results: Out of 43 patients, 11 (25.58%) patients had low risk, 18 (41.86%) patients had intermediate risk and 14 (32.56%) patients had high risk of recurrence categories. No recurrence and progression of the disease noted in low risk group. In the intermediate risk group, out of 18 patients, 4 (22.2%) patients developed recurrence and 2 (11.1%) patients had progression of disease. In high risk group, out of 14 patients, 4 (26.8%) patients developed recurrence and 2 (14%) patients developed progres­sion of the disease.

Conclusions: Even in a low volume centre of bladder cancer, effective treatment for non-muscle inva­sive bladder cancer with trans-urethral resection of bladder tumour followed by adjuvant intravesical chemo or immunotherapy can be given safely to reduce recurrence and progression of the disease.

Authors: Mansur Dil Islam , Karki Raj Kumar , Shrestha Pragya , Mehta Dilip Kumar , Maskey Sunima , Dahal Shreya
Published: October 2020

Background: The human foot shows variations in its dimensions and shape in different age group of both male and female. It can be used as gender predictor of an individual in forensic science investigations which may have a great value for identification of unknown deceased

body. This study was aimed to measure the various dimensions of foot and derive a tool to predict gender of an individual.

Methods: This study was the cross-sectional type which consisted of 556 individuals (268 males and 288 females). Foot dimensions (foot length and foot breadth) were measured in centimeter and the foot index was derived for both sexes separately. The data was analyzed using descriptive statistics with SPSS vesion 20.0.

Results: It was concluded that there were gender differences in foot length and breadth. The foot length and foot breadth were found to be higher among males than females. The bilateral differences of foot dimensions were not recorded in both male and female. There were gender differences in foot index.

Conclusions: The male is found having longer and broader foot than female foot. The foot index is not used as an appropriate tool to determine gender.
Ischemia modified albumin among type 2 diabetic patients visiting a tertiary care center of Kathmandu
Authors: Thapa Sangita , Rayamajhi Rabindra Jang , Gautam Surakshya , Dahal Sirjana
Published: October 2020

Background: Chronic hyperglycemia in diabetes may increase oxidative stress causing ischemia and long-term complications of diabetes. It may also alter albumin, increasing the concentration of serum ischemia modified albumin. The present study was conducted to estimate serum isch­emia modified albumin level and to assess its relationship with parameters of glycemic control in diabetic patients.

Methods: In this study, 130 type 2 diabetic patients were enrolled and blood samples were ana­lyzed for ischemia modified albumin, glycated hemoglobin, fasting and postprandial blood glu­cose. Parameters of glycemic control were estimated using routine standard methods and serum ischemia modified albumin was measured manually by spectrophotometric cobalt-albumin bind­ing assay. Participants with glycated hemoglobin level less than 7% were labeled as group 1 and participants with glycated hemoglobin value more than or equal to 7% were labeled as group 2.

Results: Group 2 participants had significantly higher mean serum ischemia modified albumin as compared to group 1 (p<0.001). There was significant positive correlation between ischemia modi­fied albumin and parameters of glycemic control; glycated hemoglobin (r=0.300, p=0.001), fasting blood glucose (r=0.239, p=0.006), postprandial blood glucose (r=0.318, p<0.001). However the relationship of ischemia modified albumin with age, body mass index and duration of diabetes were statistically insignificant.

Conclusions: The present study shows increase in serum ischemia modified albumin with increase in all three glycemic parameters. This finding suggests that ischemia modified albumin can be used as a marker of hyperglycemia induced oxidative stress in diabetes.

Governance and Power-Sharing in TVET in Nepal: Sharing of Practical Experiences
Authors: Winther-Schmidt Erik , Shrestha Rajendra Bahadur
Published: October 2020

Addressing the overall theme of Governance and Power-Sharing in TVET in Nepal, the paper starts by defining the key concepts. Governance surely means involvement of Government, but Government can be extended by involving civil-society actors, like the private sector, which can also play an important role in executing some roles and responsibilities. When such non-government sectors are involved in the planning, execution and financing of TVET, this is where we speak of power-sharing. To be effective, power over TEVT must be executed at many levels: at a macro level (federal level), at a meso level (provincial level), and at a micro or local level. One powerful way of ensuring this power-sharing between government and non-government in TVET is through public-private partnerships (PPP). It is argued that employers- for many good reasons- have so far not been playing their optimal role in TVET. This should change and it is argued how PPP can ensure this change. The outcome would be the bringing about of more market-relevant and demand-driven qualifications and skills that the employers say they need to staff their businesses and industries. With the point of departure in mind that GoN is presently not at the verge of reforming its overall TVET system, this is the time now where important lessons can be gathered and learned from, which can give a direction to new policy initiatives.

Penelitian ini mencoba menggali faktor protektif resiliensi keluarga dari hal yang paling dekat dengan kehidupan individu, yaitu budaya. Penelitian ini bertujuan untuk melihat apakah identitas budaya Jawa berkontribusi pada internalisasi cognitive reappraisal dalam membentuk resiliensi keluarga pada keluarga suku Jawa. Responden penelitian terdiri dari 317 orang tua, bersuku Jawa, laki-laki (35%) dan perempuan (65%), berusia 25-63 tahun (M= 44, SD=7.1) yang diperoleh melalui tehnik convenience sampling. Pengambilan data dilakukan dengan metode survey menggunakan tiga alat ukur, yaitu Walsh Family Resilience Questionare (α= 0.917), Dimensi cognitive reappraisal dari Emotion regulation Questionnaire (α= 0.793), dan Alat Ukur Identitas Budaya Jawa (α=0.818). Analisis regresi dan uji mediasi dilakukan dengan bantuan PROCESS di SPSS. Hasil penelitian melaporkan bahwa identitas budaya Jawa berkontribusi membentuk cognitive reappraisal (R2= 0.050; β= 0.229; p<0.001). Cognitive reapraissal juga dilaporkan berkontribusi membentuk resiliensi keluarga (R2= 0.076; β=0.281; p<0.001), namun perannya sebagai mediator tidak terkonfirmasi karena efek kontribusinya tidak cukup besar dibandingkan jika identitas budaya Jawa berkontribusi langsung pada resiliensi keluarga (coeff jalur a*b= 0.0569; p<0.001; coeff jalur c’= 0.9369; p<0.001).

AbstrakSatelit LAPAN-A2/LAPAN-Orari dan LAPAN-A3/LAPAN-IPB telah menghasilkan sejumlah citra satelit sejak peluncuran di, Sriharikota India, pada tahun 2015 dan 2016. LAPAN berharap bahwa hasil tracking satelit membutuhkan media penyimpanan yang memungkinkan untuk menjadi lebih mudah diakses dan menarik bagi publik. Hasil citra sampai saat ini hanya tersimpan pada folder-folder dengan penamaan khusus. Metode tersebut cenderung manual dan menyulitkan operator untuk mencari citra dengan spesifikasi tertentu. Disamping itu, kebutuhan pengguna terhadap data citra pada waktu tertentu menjadi permasalahan utama. Stasiun bumi satelit  LAPAN setiap hari secara rutin melakukan kegiatan akuisisi dan pengolahan data citra satelit LAPAN. Data citra satelit LAPAN hasil pengolahan di stasiun bumi ini kemudian diintegrasikan ke dalam satu sistem katalog dengan sinkronisasi informasi hasil pengolahan data. Oleh karena itu, fasilitas ini dirancang dan diimplementasikan untuk memenuhi persyaratan pengguna. Makalah ini akan memaparkan rancang bangun sistem baisis data katalog citra satelit LAPAN yang berbasis web dan near-real time. Sistem basis data katalog ini diharapkan dapat memudahkan pengguna di seluruh Indonesia untuk mengakses dan mengunduh data citra satelit LAPAN secara langsung.Disamping sebagai media penyimpanan, dengan menggunakan katalog citra berbasis web akan mempermudah Pusteksat untuk mendiseminasikan produk satelit LAPAN Kata Kunci: Satelit, LAPAN-A2, LAPAN-A3, katalog, basis data AbstractThe LAPAN-A2 / LAPAN-Orari and LAPAN-A3 / LAPAN-IPB satellites have produced a number of satellite imagery since the launch at, Sriharikota India, in 2015 and 2016. LAPAN hopes that the results of satellite tracking require storage media that allows it to be more accessible and attractive to the public. Image results to date have only been stored in folders with special names. The method tends to be manual and makes it difficult for operators to find images with certain specifications. In addition, user needs for image data at certain times become the main problem. The LAPAN satellite earth station routinely conducts acquisition and processing of LAPAN satellite image data every day. The LAPAN satellite image data from the processing at this earth station is then integrated into one catalog system by synchronizing information from the data processing. Therefore, this facility is designed and implemented to meet user requirements. This paper will describe the design of a web and near-real-time LAPAN satellite image catalog data analysis system. This catalog database system is expected to facilitate users throughout Indonesia to access and download LAPAN satellite image data directly. Aside from being a storage media, using a web-based image catalog will make it easier for Pusteksat to disseminate LAPAN satellite products. Keywords: Satellite, LAPAN-A2, LAPAN-A3, catalogue, database

Published: October 2020

Era keterbukaan informasi serta kecepatan akses dan konektivitas memungkinkan masyarakat untuk mencari informasi dengan mudah tanpa batas jarak dan waktu. Kemudahan akses informasi bisa berdampak positif dan juga negatif. Tak terkecuali di bidang kesehatan dan pelayanannya. Tantangan terbesar salah satunya adalah terjadinya misinformasi karena masyarakat mendapatkan informasi terkait kesehatan dari sumber yang belum jelas kebenarannya. Tantangan lainnya yaitu semakin berkembangnya jenis-jenis penyakit dan diagnosa-diagnosa baru yang kemungkinan belum pernah ditemukan sebelumnya, keharusan bahwa antara penyintas dan paramedis harus berada di tempat dan waktu yang sama, serta kesulitan dalam mendapatkan akses layanan kesehatan yang memadai. Untuk mengatasi berbagai permasalahan tersebut, salah satu solusi yang dapat dikembangkan yaitu dengan membangun web telemedicine berbasis cloud. Web telemedicine memiliki berbagai fitur antara lain: konsultasi langsung secara daring dengan dokter, mendapatkan resep untuk penyakit-penyakit ringan sehingga memudahkan pasien dalam mendapatkan obat di apotik terdekat, serta rekomendasi penanganan lanjutan ke rumah sakit untuk pasien yang membutuhkan tindakan penunjang. Web telemedicine ini mengutamakan kemudahan akses bagi pasien dan dapat digunakan dengan telepon pintar sehingga diharapkan web telemedicine dapat meningkatkan kesadaran masyarakat akan pentingnya mendapatkan layanan kesehatan yang terpercaya dan mudah dijangkau.

Preparation of silicon boride SiBx (x = 3, 4, 5, 6) powders by chemical oven self-propagating combustion synthesis
Authors: Liu W. , Feng P. , Ren X. , Zhu L.
Published: October 2020

A new method was developed for quickly preparing a highemissivity silicon boride compound of SiBx (x = 3, 4, 5, 6) by highly exothermic Ti-TiO2-Si-Al chemical oven preheating. The SiBx combustion synthesis process and adiabatic combustion temperature were investigated. A large exothermic reaction occurred at the combustion temperature of 1 700 K. X-ray diffraction results indicate that an SiBx phase and a substantial amount of unreacted Si were identified in the products. By increasing the boron content until the Si-B ratio reached to 1 : 6, the diffraction peaks primarily indicated SiB6, SiB4, and Si11B33 in the final product. According to the spectra and quantitative results, the atomic chemical composition ratio of Si and B was close to the nominal composition. Thus, this method offers an efficient way to produce Si-B compounds with less time and energy consumption than current methods.

Boron-added steel has been used in several automotive components in which the energy absorbed in impact testing is an important requirement. Previous thermodynamic studies have shown that boron addition promotes significant change in equilibrium phases, increasing the volume fraction of precipitated phases, mostly due to increased carbide stability and formation of borocarbides. As volume fraction, size and distribution of precipitates influence the absorbed energy in impact testing of steels, it is important to study M23(B,C)6 borocarbide precipitation and coarsening kinetics and its effects on Charpy V-notch absorbed energy of boron steels. In the present work, borocarbide coarsening kinetics were evaluated using optical microscopy in samples heat-treated at 880 0C for different times. The borocarbide coarsening kinetics data suggest that growth is controlled by an interfacial reaction mechanism. The Charpy V-notch absorbed energy decreases with increasing borocarbide section size and the embrittlement was successfully described by an empirical equation.

In this study, the synergistic effects of 2-mercaptobenzotiazole molecules and zinc nitrate on the corrosion behavior of carbon steel were investigated using electrochemical techniques in 3.5% NaCl solution. The experimental results revealed that combination of 2-mercaptobenzoimidazole (MBT) and zinc nitrate with ratio of 100 ppm : 100 ppm, resulted in the least corrosion current (1.03 lA cm-2) and the highest corrosion inhibition efficiency. Polarization results showed that the inhibition mechanism of inhibitor was mixed-type (anodic and cathodic mechanism) corrosion inhibition which was predominantly influenced by a reduction in dissolution rate of the substrate (decrease in anodic current density). Electrochemical impedance spectroscopy analysis yielded more accurate results about the formation mechanism and stability of the inhibitor film over prolonged time. The precipitation of chelate from inhibitor molecules and zinc cations on steel surface was found to be the main mechanism for increasing the corrosion resistance of steel substrate.

Content with content: A content-based instruction approach to curriculum design and course assessment in academic English for business
Authors: Kirkham Deak
Published: October 2020

This article reports on the successful implementation of a content-based instruction (CBI) approach to a 6-month pre-sessional academic English for business and management course at a UK university. While recognising that CBI is not a ‘cure-all’ and indeed that the approach brings with it particular issues, such as instructor competence in the content, the article argues CBI offers both significant and wide-ranging benefits as a language teaching approach and as such should be given greater prominence in the language teaching industry.
Being at home: Global citizenship in Norwegian schools. A study of children’s poems
Authors: Erdmann Susan , Gawronska Barbara
Published: October 2020

The paper addresses the question of self-perceived identity in children attending international schools in Norway. In this population, the distinction between “home culture” and “host culture” is no longer relevant, since most of the children represent “hyphenated” (e.g. Asian-British or American-Scandinavian) or merged nationalities and cultures. The goal of the study is to investigate how these pupils define themselves and the notion of “home”. To achieve at least a preliminary picture of the children’s self-perception, the authors have analysed poems on two topics: Me and Home, written by pupils of an international school and a Norwegian school, both informant groups aged 11-13. A semantic analysis of the poems indicates that the international school children present strong assertions of individual identity as defined against societal roles, while the Norwegian school pupils do not conceptualize identity formation as a struggle and their poems reflect a high degree of social, familial and national integration.
English-Polish contrastive grammar at Polish universities
Authors: Mańczak-Wohlfeld Elżbieta
Published: October 2020

Although contrastive studies do not enjoy great prestige among linguists, they have a very long tradition dating back to ca. 1000 A.D. when Ælfric wrote his Grammatica, a grammar of Latin and English. Even then he must have been aware of the fact that the knowledge of one language may be helpful in the process of learning another language (Krzeszowski 1990). Similarly, it seems that throughout the history of mankind teachers of a foreign language must have realized that a native and foreign tongue can be contrasted. However, contrastive linguistics only came into being as a science at the turn of the 19th and 20th centuries. The first works were almost purely theoretical, and it is worth emphasizing that among the first scholars working in the field was Baudouin de Courtenay, a Polish linguist, who published his contrastive grammar of Polish, Russian and Old Church Slavonic in 1912. The outbreak of the Second World War was a milestone in the development of applied contrastive studies since a need to teach foreign languages in the United States arose as a result. The 1960’s is considered a further step in the development of contrastive grammar since a number of projects were initiated both in Europe and in the U.S.A. (Willim, Mańczak-Wohlfeld 1997), which resulted in the introduction of courses in English-Polish contrastive grammar at Polish universities. The aim of the present paper is to characterize and evaluate the courses offered in the English departments of selected Polish universities and to suggest an “ideal” syllabus.
Prosodic organization of English folk riddles and the mechanism of their decoding
Authors: Taranenko Larysa
Published: October 2020

The paper advances a cognitive model representing a creative mechanism of riddle decoding by its recipient, which serves as a theoretical and methodological ground for the experimental phonetic study of prosodic means that organize the text of a riddle. Within the process of cognitive model formation the author performs a conceptual analysis of the riddle compositional structure, presented as a systemic algorithmic scheme. It is confirmed that a characteristic feature of a folk riddle is its division into two elements: the first one is the description of an object, further differentiated into “topic” and “commentary”, while the second one is the riddle answer, or solution, generated directly in the recipient’s mind as a result of his/her mental activities. The carried out auditory analysis proves that such a limitation of the riddle’s structure is compensated by a set of prosodic means and their specific interaction, which trigger creative and cognitive processes in the recipient’s mind aimed at searching for the riddle solution.
‘TAM’ in English constructions vs. Polish renditions – Selected transference pitfalls
Authors: Chłopek Dorota
Published: October 2020

This paper argues that a cognitive, constructional, view of the English categories of tense, aspect, and mood (‘TAM’) influences comprehension resulting in a more accurate grammatical performance by Polish users of English. Five English constructions considered to be transference pitfalls for Polish users are highlighted through juxtaposing original examples from The Hobbit by Tolkien (1937/1978) with three Polish renditions. The pitfalls addressed in this paper concern absence of equivalent Polish constructions to English expressions in the perfect aspect, the progressive aspect and to English constructions which ‘lexicalize’, i.e. convey with words, a compilation of the perfect and the progressive aspects. The Polish versions of the examples analysed and discussed in the present paper demonstrate a variety of means in which Polish grammar is used to handle the disparities between the English and Polish versions. The objective of the paper is to apply a cognitive interpretation to the aforementioned English constructions.
