Holistic Approach to Collaborative Immersive Virtual Environments in Education: eDIVE Design Case Study
Authors: Šašinka Čeněk , Chmelík Jiří , Šašinková Alžběta , Stachoň Zdeněk
Published: June 2023

This article provides a comprehensive framework for CIVE (Collaborative Immersive Virtual Environment) education, encompassing educational lessons and methods and the eDIVE platform, an original software solution designed for formal and non-formal education. Such a holistic and complex approach was employed to bring the actual implementation of CIVE a step forward finally. The rise of IVR (immersive virtual reality) technology, particularly head-mounted displays (HMDs), has enabled extensive use of this medium in education. However, this has led to new questions and needs concerning its practical utilization, including what software tools and functions to prioritise and how to implement this new medium in educational systems. Drawing on the results of previous research, the authors designed a new platform, teaching methods, and educational content that take advantage of CIVE, validating the solution by deploying it directly in both formal education at universities and high schools and non-formal education as part of the library system. To effectively deploy CIVE, it is essential to consider all three levels simultaneously: technological, instructional, and institutional. For example, the eDIVE platform was designed to allow collaboration in a fully immersive environment using HMDs, while also offering the possibility to participate using a conventional 2D user interface to ensure inclusivity. From an instructional design perspective, there is a need to move away from learning methods that have merit and advantages based in a real-world environment but fail to exploit the potential and strengths of the new medium fully. Conversely, it is necessary to reflect on the limits of CIVE and avoid topics and practices for which conventional RE (Real Environment) is more effective. At the institutional deployment level, appropriate forms of teaching need to be sought or existing ones adapted, such as synchronous distant learning through library networks. On the other hand, mass deployment of VR HMDs into mainstream classrooms and standard time-limited lessons has proved ill-suited. There are many creative and effective ways to use CIVE. Still, it is advisable to reflect on the limitations of the technology and instead use it primarily for topics in which its full potential will be utilised to the maximum extent possible.

Authors: Kasarla Rajeshwar Reddy , Verma Aishwarya , Pathak Laxmi
Published: June 2023

Background and Objectives: The professional attitude of the Doctor is mainly concerned with his/her feelings, beliefs and behavior towards the patients. The students are admitted to MBBS through a written test (entrance test) in three subjects’ viz. Physics, Chemistry, and Biology to qualify for the admission. But, no test is conducted to evaluate the attitudes of students, who seek admission into medical colleges. Hence, this study was undertaken to evaluate the attitudes of medical students i.e., whether they have right/positive attitude for the medical profession.
Material and Methods: A descriptive, cross-sectional study was carried out on 100 MBBS students of 4th and 5th year of Universal College of Medical Sciences, Bhairahawa, Nepal by administering a questionnaire constructed on the lines of Likert’s summated rating scale to measure the attitudes of MBBS students towards medical profession. The tool consisted 32 statements, both positive as well as negative. Each statement had four alternative responses against it, namely – Strongly Agree (SA), Agree (A), Disagree (DA), and Strongly Disagree (SD). The questionnaire in Google form was mailed to all students. The students were asked to read each statement carefully and click on their opinion/response.
Results: This study revealed that the gender, parents’ occupational background, and socio-economic status influences the attitudes of 4th and 5th year MBBS students and differ significantly towards their medical profession. Whereas age, locality, and nationality were not influencing factors for the attitudes 4th and 5th year MBBS students towards their medical profession.
Conclusion:  The present study on attitudes of MBBS students towards medical profession has several important implications for medical education. The findings of present study could be helpful to the planners, policy makers of medical education, so as to bring changes in entrance test for admission into MBBS course, and helpful to medical colleges and medical teachers so that they can conduct counselling and guidance programs so as to promote a positive attitude among medical students towards medical profession. Research literature of this type will serve as a self-instructional material for MBBS students to understand their medical profession in a scientific manner.

Published: June 2023

Background and Objectives: Elder abuse is a single or repeated act, or lack of appropriate action, occurring within any relationship where there is an expectation of trust, which causes harm or distress to an older person. Around 1 in 6 elders experience some form of abuse worldwide causing bad impact on health as well as quality life of elders. Most of the studies indicate that elder people are suffered from different types of abuse which include: neglect (isolation, abandonment and social exclusion), violation (of human, legal and medical rights), and deprivation (of choices, decisions, status, finances and respect). Thus, this research was carried out to identify the prevalence of elderly abuse and its associated factors among elderly people.
Materials and Methods: A descriptive cross sectional research design was adopted in total 60 samples who were selected by non probability purposive sampling technique. Data was collected through door to door survey using face to face interview schedule using Geriatric Mistreatment Scale (GMS). The collected data was analyzed using descriptive statistics such as frequency, percentage, mean, standard deviation and inferential statistics such as Chi-square test by using Statistical Package of Social Science (SPSS) 16th version.
Results: The present study findings revealed that prevalence of elderly abuse was 35%. Among different types of elderly abuse, most of the respondents had faced psychological abuse (38.3%), neglect was faced by 20% of the respondents and 20% had to face financial abuse. Minority (5%) had faced physical abuse and none of the respondents had faced sexual abuse. Overall, 35% of the respondents had faced any form of the elderly abuse. The prevalence of elderly abuse had statistically significant association with living arrangement of elderly people and future saving as p-value was 0.045 and 0.023 respectively.
Conclusion: The study was concluded that elderly abuse is prevalent in community of Kathmandu. Therefore, the elders are at risk of getting victim of elderly abuse, so effective screening and awareness regarding prevention of elderly abuse is very essential.

Authors: Swaroop Shikha , Mittal Medha , Nair Smita , Saini Reetika , Bagla Jyoti
Published: June 2023

Introduction: Various research works have reported elevated serum homocysteine levels with the use of antiepileptic drugs. This may lead to an increased risk of atherosclerosis, a higher seizure frequency and may also cause cognitive decline.
Methods: Twenty five children (Two to 12 years) on valproate monotherapy for more than one year and the same number of age and sex-matched healthy controls were enrolled. Venous blood samples were analyzed for serum homocysteine, vitamin B12 and folic acid levels. All biochemical parameters were compared between the groups.
Results: The antiepileptic drug users had significantly lower serum homocysteine levels and higher B12 levels as compared to the controls. But serum folate levels were similar between the groups. No correlation of serum homocysteine levels was observed with either serum folate, B12 or valproate.
Conclusions: The use of valproate monotherapy for epilepsy in the Indian paediatric population does not increase the risk of hyperhomocysteinemia.

Agency of Trauma in Anand's Untouchable and Roy's The God of Small Things
Authors: Nepali Mukta Bahadur
Published: June 2023

Mulk Raj Anand's Untouchable (1935) and Arundhati Roy's The God of Small Things (1997) seek to represent the traumatic sufferings of the scheduled castes in the caste-ridden Indian society. The authors of the novels under study are not from the scheduled-castes the traumatic sufferings of whom they have tried to represent in the novels. When such is the case, the problematic resides in the authenticity of voice in the representation of dalits' traumatic sufferings. The traumatic pain of the downtrodden people the authors enact in the novels evokes the affect of sympathy in the readers. However, the big question in trauma theory is not just the sympathy that the authors evoke in their readers towards the traumatized protagonists but whether the evocation carries the direct voice of the authors and the middle voice. The projection of dalit subjectivity accompanied by the academic vocation also evokes the affect of sympathy, besides the construction of pain in the transaction between language and body. The agency of trauma supports the representation of dalits' trauma only when the authentic voice of the authors accompanies the narrativization of pain. Examined in the light of Dominick LaCapra's notion of the middle-voice and Melissa Gregg's idea of communicating investment, this research has come to the conclusion that Anand's representation of dalits' trauma in Untouchable carries the agency of trauma, which is consistent throughout the novel, whereas; Roy's representation of dalits' trauma remains ambivalent vis-à-vis the consistency of the agency of trauma in the novel The God of Small Things. Therefore, the intensity of the agency of dalits' trauma in Untouchable is more intriguing than in The God of Small Things.

Predicting Stiffness Asphalt Natural Rubber Latex Modulus Value Using Multiple Linear Regression Analysis
Authors: Yudian Budi Krishna  , Ramadhani  , Hendrik Jimmyanto
Published: June 2023

Every year, population growth increases, which causes a rise in the number of drivers. The road may become damaged as a result of this condition, necessitating repairs. Deformation and cracks in the pavement structure are the main contributors to damaged road conditions. Using natural rubber materials, such as natural rubber latex, is one of the modified asphalt methods that can solve this issue. The stiffness modulus is the asphalt's reaction to a load applied to it; this reaction can be used to evaluate the asphalt's rheological characteristics. While there was only an equation describing the stiffness modulus of oil asphalt up until now, and no research on the stiffness modulus model of rubber asphalt, the suggested study examines the prediction of the stiffness modulus model of latex natural rubber asphalt. The factors taken into consideration are natural rubber latex content, penetration, and softening point. Multiple linear regression analysis has been performed on the data, and the model validation results show an average error of 3.28% with a data distribution that is similar to the linear line with an R2 value of 0.9917.

Published: June 2023

In Indonesia, 39 watersheds were deemed essential in 1994, and the importance of watersheds grew in 2000. The existence of a watershed has the role of being able to sustain water availability, maintain the balance of the ecosystem and as a container for flowing water. The Musi-Sugihan-Banyuasin-Lemau River Area (WS MSBL), which has an area of 86680 km2 and is made up of 23 primary watersheds, is one of the largest watersheds in the Sumatra region. Research was done to determine the state of the watershed so that a strategy for watershed conservation could be chosen. In-depth interviews with stakeholders in the form of focus group discussions (FGD) were utilized as the study method to collect both secondary and primary data about the circumstances of the watershed as well as to gain in-depth management outcomes. The study's findings demonstrate that managing the WS MSBL watershed involves more than only technical issues; it also necessitates involving associated institutions and stakeholders, necessitating the creation of operational watershed management strategies.

Authors: Ardana Affan
Published: June 2023

Purpose: The research aims to find the best parameters and features for predicting stock price movement using the XGBoost algorithm. The parameters are searched using the RMSE value, and the features are searched using the importance value.Design/methodology/approach: The research data is the stock data of Amazon.com company (AMZN). The dataset contains the Date, Low, Open, Volume, High, Close, and Adjusted Close features. The dataset is ensured to have no missing data by handling missing values. The input feature is selected using the Pearson Correlation feature selection method. To prevent the difference between the highest and lowest stock price from being too far apart, the data is scaled using the scaling method. To avoid bias that may appear in the prediction result, cross-validation is used with the Min Max Scaling method, which will devide the dataset into training data and testing data within a range of 30 days after the training data. The parameters to be tested include n_estimator = 500, early stopping round = 3, learning rate = 0.01, 0.05, 0.1, and max_depth (tree depth) = 3, 4, 5.Findings/result: The result of the research that a learning rate of 0.05 and a tree depth of 5 obtained the lowest RMSE result compared to other models, with an RMSE of 0.009437. The Low feature obtained the highest importance value among all the models built.Originality/value/state of the art: This study used testing data within a range of 30 days after the training data and used a combination of parameters, including n_estimator = 500, early stopping round = 3, learning rate = 0.01, 0.05, 0.1, amd max_depth (tree depth) = 3, 4, 5.

Ikan Kerapu Cantang (Epinephelus fuscoguttatus >< Epinephelus lanceolatus) adalah salah satu produk budidaya utama di Indonesia dan mempunyai nilai harga yang tinggi yaitu berkisar mulai dari Rp. 110.000 hingga Rp.120.000/kg dan sudah menjadi komoditas ekspor penting terutama ke Hongkong, Jepang, Singapura dan Cina. Metode Hidroakustik merupakan metode deteksi objek (ikan) bawah air baik di kolam maupun di laut dan Nilai Target Strength (TS) merupakan parameter utama untuk menduga objek dibawah air, oleh karena itu perlunya dilakukan penelitian terkait nilai Target Strength (TS) dengan tujuan untuk mengetahui nilai hambur balik Ikan Kerapu Cantang yang selanjutnya akan dihubungkan dengan ukuran ikan tersebut. Berdasarkan hasil pengukuran terhadap 30 sampel Ikan Kerapu Cantang yang terdiri dari berbagai macam ukuran, maka nilai TS yang didapat berkisar dari -56,17 hingga -40,4. Hubungan linier positif dapat terlihat dari hasil uji statistik yaitu mempunyai nilai R2 0,8. Berdasarkan hasil statistik di atas bahwa nilai rata-rata TS dipengaruhi nilai TL Ikan Kerapu Cantang. Adapun hasil dari uji statistik tersebut didapatkan persamaan sebagai berikut: TS200kHz = -87,92+42,75log10 (TL) (95% CI: -44,39 to -49,01 dB, 9 to 10 TL mm; R2=0,83).
