Design of Next-generation Virtual Library for Free Movement in a 360-degree Perspective
Authors: Et.al Li Xuezhen
Published: April 2021

In this research, we design a virtual library that allows users to have a 360-degree perspective and move freely. We will focus on the function of the library not only as ‘a public facility for lending books’ but also as ‘a place for encountering new knowledge by accident.’ In modern open-stack libraries, the function of ‘a place for encountering new knowledge by accident’ is realized through the act of ‘walking around’. However, regarding the online libraries and digital libraries, which have been rapidly developing in recent years, they offer scarce functionality of ‘encountering unknown knowledge by accident’ by ‘walking around in the library’, while increasing convenience through digitization.In light of this problem, this paper devises a virtual library equipped with the function that users can move freely in the library in a 360-degree view’. By providing the state of bookshelves and books which are on display by actual 360° videos rather than artifacts such as CG or animation, users can acquire necessary related information of books while having the realistic experience of being in the library. Past digital libraries are reproductions of libraries as building structures, and the libraries’ original function of encountering books and knowledge was low. On the contrary, as for the online libraries, users can only search for book information, and cannot obtain the sense of being in the library. This study proposes a new virtual library that combines past digital library and online library.
A Study of BLE Mesh Network Scheduling Algorithm Using A Smartplug
Authors: Et.al Goo Kim
Published: April 2021

This paper proposes a BLE Mesh network scheduling algorithm using SmartPlug. And proposes random-backoff, a very simple method for collision avoidance. The low-energy scheduling algorithm of SmartPlug and BLE node is proposed. SmartPlug periodically broadcasts its own information to inform the surrounding BLE nodes and SmartPlug. A node for data communication with SmartPlug is decided for efficiency. The BLE node periodically transmits data and switches to sleep mode after data transmission. In this paper, propose a very simple method, random-backoff, to reduce collisions when transmitting data in a BLE node. In the simulation of results shows when the data size is 1 ~ 31 bytes and 32 ~ 255 bytes, and random-backoff is effective when 1~31 bytes length. In the case of 32 to 255 bytes, random-backoff is not effective, so additional research is needed. And the simulation conducts under the same condition, but it shows that the data length and the number of transmission attempts has an effect. The simulation results show the transmission success ratio is similar regardless of the data length when random-backoff is not applied. It also shows the number of transmission attempts has an effect. Also, this simulation shows the results that as the number of nodes increases, the wireless environment becomes congested, and the transmission success ratio decreases. As a result of the simulation, random-backoff for collision avoidance is effective in transmitting data of 1 to 31 bytes better than 32 to 255 bytes in the data length.

An Improving Method for Performance of DNN using 2-bit Quantization
Authors: Et.al Sang Hyeok Kim
Published: April 2021

Background/Objectives: Recently, interest in AI(Artificial Intelligence) has increased, and  many studies are being conducted to enable AI to be used in embedded and mobile environments. Among them, quantization is one of the methods to reduce the size of the model, and most quantization of less than 8 bits cannot be implemented without additional hardware such as FPGA. With this in mind, in this paper, we propose two new algorithms that can implement 2bit quantization in software.

Methods/Statistical analysis: In this paper, we propose a packing operation that quantizes a weight consisting of 32-bit real values into 2 bits, stores four 2-bit quantization weights in one 8-bit memory, and a Masking Matrix Multiplication function that performs the calculation of the packed weight and input values. These functions operate in parallel in the GPU memory.

Findings: The quantization model using the above function showed about 16 times more memory saving and 4 times faster when comparing the operation with the existing 32bit model. Nevertheless, the DNN model showed an error of around 1% in learning using MNIST and HandWritten data, and the CNN model showed an error of around 1% in learning using EEG (Electroencephalograpy) data.

Improvements/Applications: The function used in this study is focused on the domain of DNN, and although extended to CNN, quantization could be performed only in the FC (Fully Connected) part. To apply to the convolution layer, an additional function is required, and it is necessary to check whether the difference in accuracy is small even in a more complex data set in the future.
Factors Affecting the Hardness Characteristics of Microstructures in Gas Carburized Chromium Alloy Steels
Authors: Et.al Chang-Yeol Oh
Published: April 2021

We analyzed the factors affecting the gas carburizing microstructure of parts for constant velocity joints. Gas carburizing 0.15-0.20C1.13-1.14Cr chromium alloy steel used in automobile drive units is characterized by changing the properties of the carburizing layer in the depth direction.

The experimental conditions were set to enable field application. The components of the specimen to be used for gas carburization were analyzed by X-ray fluorescence. Changes in the mechanical properties of the carburized layer were analyzed by micro-hardness, microstructure, and carburizing content. The gas carburization cycle was selected based on the simulation results. The characteristics change before and after carburization of two samples with different carbon and chromium content were analyzed.

The carburization temperature that can be used for manufacturing automobile parts was 930°C, the carbon potential required for carburization was 0.90wt%, and the carbon potential required for diffusion was 0.75wt%. The inner and outer hardness values of the carburized layer satisfying the effective hardening depth of 550Hv were 400Hv-740Hv. In the case of 0.20C alloy steel, the effective hardening depth with a carburizing amount of 0.36wt% and a hardness of 550Hv was 1.467 mm. also in the case of 0.15C steel, its effective hardening depth was 0.746 mm. The simulation results for selecting the carburizing heat treatment conditions and the carbon change in the carburizing layer showed a similar trend. The carburizing structure related to hardness change was martensite. As a result of EPMA, SEM, and XRD analysis, the amount of carburized and the amount of martensite structure correlated, and the martensite increased as the amount of carburized increasing. As a result of EPMA analysis, the smaller the carburizing content the greater the depth of carburization.

We intend to proceed with optimization conditions for mass production in connection with wear resistance and fatigue. It is expected that these results will contribute to the improvement of durability of automobile driving parts.
A Study on Preemptive Response to Equipment Problems in Public Address System
Authors: Et.al Taeha Ryu
Published: April 2021

In this study, in preparation for equipment failure of emergency broadcasting equipment, we intend to propose a method to respond in advance to situations where abnormalities are visible.In the case of a short circuit in the speaker line in the emergency broadcasting system, high current from the power amplifier enters the line again and damages the power amplifier, making audio output impossible. As a method to prevent this, a method of separating the speaker line from other lines is mainly used in order not to affect other speaker lines when a short circuit occurs.In this study, a method for establishing a safety system with a higher level than the standard recommended by the government in emergency broadcasting system was studied and suggested. The method is to respond in advance by monitoring and analyzing the prognostic symptoms that appear before the actual failure occurs.For example, if a problem occurs in the system, the problem is solved by replacing the part or removing the time factor of the problem. However, before a failure occurs, there are cases in which the occurrence and cancellation of failure symptoms for a short period of time occur periodically or aperiodically. In this case, the possibility of actual failure is determined in advance by analyzing it as a precursor to the actual failure.In the event of a situation that appears to be a pre-specified potential failure, we propose techniques to diagnose it early and tell the manager how to take action.

Interactive Content Using Newtro With A Focus On Hand Interface
Authors: Et.al Haram Choi
Published: April 2021

With recent advancements in technology, there has been a tendency to increase the amount of interactive content, e.g., technology combined with cultural content. Based on this, interactive content has been created based on ‘Newtro.’ In view of the physical interactions between users and content, interactive content with an interface for connecting users and content was set as the object of this study. To apply the physical interaction (considered the most important aspect of the content), ‘a button interface’ requiring a relatively greater force was used. When the user pressed the button, the video was played on a projector. The physical interactions between users and content were discussed, and an interface for connecting users and contents to thereby apply physical interactions to content was studied. A questionnaire survey was conducted, targeting users who experienced the content, and research results were derived. Therefore, this study is meaningful in that it addresses the physical interactions between users and content and examines the correlation between the physical interface and interaction. Although using a button interface was helpful for the physical interaction, a relatively simple technique was used; this could reduce user interest in the content. Therefore, research on interactivity and interfaces that can promote more active communication between content and users is required.

Authors: Et. al. Dalila Binti Abu Bakar,
Published: April 2021

We investigate if Malaysian listed companies engaged in financial information fraud during financial distressed after two years of US subprime mortgage crisis.We also investigate the impact of financial information fraudulence in bankruptcy prediction and misclassification errors. This study used consumer product companies listed on the main board and the timeframe is from 2011 till 2015. The Altman Z score indicates that 37 out of 133 Malaysian consumer product companies are financially distressed. Meanwhile, the M score shows that 28 out of 224observations are engaged in financial information fraudulence. However, these results are relatively low because the samples are taken from the main board and fraudulence in their financial statements might be done in lower magnitude in order to avoid sanctions by the Security Exchange Commission. Logistic regression was used to measure the predicting accuracy. The result of the overall accuracy percentage slightly improved by 0.9 after eliminating fraudulent companies. The confusion matrix result i.e. before and after the removal of financial information fraudulent companies, the misclassification errors especially type one has improved. This finding satisfied objective three, whereby one of the reasons for the deterioration in financial distress prediction is due to the upward bias of financial information fraudulence.Governments, monitoring bodies, and all those involved in an insolvency process would benefit from this study.

Authors: Ramesh M.K. , Kalaivanan K. , Durairaj S. , Selladurai G.
Published: April 2021

Background: Agricultural chemicals, metals, industrial effluents, plastics, excessive dumping of unused and expired pharmaceutical chemicals etc. contaminate terrestrial, aquatic and aerial environment. The excessive usage of the unwanted chemicals elicits undesirable effects in the non target organism inhabited in the various environments. The soil biota like earthworm faces threats of the environmental contaminants. A number of research works has been carried out to study the impact of certain environmental pollutants on the terrestrial inhabitant like earthworms which are widely utilized in the waste disposal management. Tamarind shell waste is considered one of the unwanted materials dumped in the road side and being discharged from industry and from the houses. The bio waste is now a day’s utilized for various purposes. The environmental contaminants such as diclofenac and bisphenol-A are discharged into the environment and finally reach the terrestrial environment where the inhabitants are adversely affected. Hence the study has been focused to analyze the efficiency of earthworm Eudrilus eugeniae in the conversion of tamarind shell waste mixed separately with Diclofenac and bisphenol-A. Methods: Vermibed was prepared for the present work. The vermibed contains cow dung and garden soil which are common in all the pots. One pot was considered as control. The second pot was mixed with tamarind shell waste. The third pot was mixed with diclofenac and finally in the last pot bisphenol-A was taken. Healthy earworms were selected and released to the four pots. The experimental set up was maintained for 30 days. Correlation matrix and t-test was performed to understand the significance of the results. Result: The study revealed the impact of pollutants on the bioconversion of tamarind shell waste. The contaminants like diclofenac and bisphenol-A significantly decreased the micro and macro nutrient levels. The phosphorous, nitrogen and potassium level showed a decrease when compared to control on 30th day in the diclofenac treatment. The nitrogen value was also decreased in the bisphenol-A treated compost on 30th day and the value was statistically significant. The other nutrients, phosphorous and iron were also decreased significantly (P less than 0.05) in the treatment and correlation matrix showed positive and negative correlation with micro and macro nutrients. The physico-chemical characters such as pH and electrical conductivity are also altered in the experimental conditions.

Published: April 2021

Background: Bovine ocular squamous cell carcinoma also called cancer eye, represents the most economically important neoplasm in large animals. Hereditary factors, environmental factors (e.g: latitude, altitude, exposure to sunlight), lack of eyelid pigmentation, age and dietary habits have all been reported to play a role in the etiopathogenesis of bovine ocular squamous cell carcinoma. In addition, in cattle the etiology has been linked to a number of viral agents, especially bovine papilloma virus and bovine herpes virus type 1 and 5. Nevertheless, ultraviolet light, viruses and circumocular pigmentation are the major epidemiologic risk factors for the development of the tumor. The efficacy of different treatment modalities for eye cancer in bovines was studied. Methods: All the animals were divided in to four groups of six animals each. Surgical excision, intra lesion BCG vaccine, surgery with auto vaccine and surgery with mitomycin was the treatment protocols followed. Immunohistochemical studies were conducted to know the rate of proliferation of bovine ye cancer. Immunopositive reaction was observed against Vascular Endothelial Growth Factor and Epidermal Growth Factor Receptor in all the cases. Result: The benefits of different treatment modalities depended on nature, type, location and extensiveness of tumor. Early detection and aggressive treatment were essential in the successful management of these tumors. A multimodal treatment approach was recommended with surgery, immunotherapy and chemotherapy in providing 100% disease free interval.

En el año de 2019 en la provincia de Wuhan, China, se reportó un brote de neumonías atípicas, con síntomas similares a los del Síndrome Respiratorio Agudo Severo (SARS), brote reportado en el 2003, y al Síndrome Respiratorio del Oriente Medio (MERS), brote reportado en 2012 en Arabia Saudita.  Esta enfermedad emergente fue causada por el nuevo coronavirus “Síndrome Respiratorio Agudo Severo Coronavirus 2” (SARS-CoV-2) o también denominada COVID-19 del inglés Coronavirus desease 2019, caracterizado por presentar severos problemas respiratorios y diversas manifestaciones extrapulmonares.
Al momento se ha reportado una elevada tasa de mortalidad en individuos del sexo masculino, en adultos mayores de 60 años, y en personas con comorbilidades como diabetes obesidad, hipertensión y problemas cardiacos. La diabetes es una enfermedad caracterizada por resistencia a insulina, pérdida de función de células β en el páncreas, y desbalance del sistema inmune por el estado de inflamación crónica. En pacientes graves con COVID-19, se ha observado una secreción alterada de citocinas pro inflamatorias, si esto ocurre en un paciente diabético, que ya tiene un estado inflamatorio per se, se induce inflamación exacerbada y una falla multiorgánica que puede desencadenar en la muerte de los pacientes. Diversos autores señalan como hipótesis que la hiperglicemia favorece la replicación viral, por lo que en un paciente “diabético con infección COVID-19”, es primordial mantener un control glicémico adecuado.
Los tratamientos para COVID-19 se han enfocado en disminuir los síntomas, el uso de antivirales, antiinflamatorios, anticuerpos monoclonales y plasma convaleciente COVID-19 ha mostrado resultados variables. Para el control de esta infección viral es necesaria una vacuna, al momento existen más de 150 candidatos, con una eficiencia que va del rango de 70 al 95%, pero aún falta determinar la inmunidad a largo plazo en las personas vacunadas. Esta revisión aborda las características de la infección por SARS-CoV2 y la respuesta inmunitaria en pacientes diabéticos frente a COVID-19.

Development of monthly seawater intrusion vulnerability assessment method using GALDIT
Authors: Kim Il hwan , Chung IL-Moon , Chang Sun Woo
Published: April 2021

Accurate diagnoses of vulnerability of seawater intrusion (SWI) into
aquifers are required to ensure sustainable utilization of groundwater
resources in coastal areas. GALDIT was selected to assess the SWI
vulnerability on western coastal areas of South Korea. Climate change
trends are updated every year. The existing GALDIT method has various
scores to express the changing observed values. However, they are
limited because of their sensitivity in the assessment of regional
characteristics or climatic change due to low weight flexibility.
Therefore, this study assessed vulnerability to SWI by classifying the
existing GALDIT into static and dynamic parameters. The static
parameters include groundwater occurrence (G), aquifer hydraulic
conductivity (A), and distance from the shore (D), whereas the dynamic
parameters include height to groundwater level above sea level (L),
impact of existing status of seawater intrusion (I), and aquifer
thickness (T). The monthly mean was used as the dynamic index to reflect
monthly variations. To indicate the temporal trend of parameter L was
calculated based on the data observed at the sea level station adjacent
to the groundwater level station. To sensitively reflect the monthly
changes in values, the range of scores was divided into 10 parts. The
calculated GALDIT index showed that the most vulnerable month was
September. In the progress of SWI, vulnerability was assessed monthly to

The aim of the study was to estimate the genetic parameters for reproductive performance in native breed sows covered by genetic resource conservation programmes in Poland. The study used data on reproductive performance of 1,182 Złotnicka White sows, 1,648 Złotnicka Spotted sows and 1,180 Puławska sows. The following traits were analysed: age at first farrowing, number of piglets born alive, number of piglets at 21 days of age and farrowing interval. Covariance components and genetic parameters were estimated using an REML animal model with different combinations of fixed and random effects. Convergence of the iterative process was achieved by the selection of the AIREML algorithm. The estimated values of the coefficients of heritability for the number of piglets born ranged from h2 = 0.09 in the Puławska breed to h2 = 0.30 in the Złotnicka White breed. For the number of piglets reared, they varied between h2 = 0.09 in the Złotnicka Spotted breed to h2 = 0.27 in the Puławska breed. The heritability values for age at first farrowing and farrowing interval were higher, and ranged from 0.4 to 0.5. The significant positive and negative coefficients of phenotypic correlation, estimated between age at first farrowing and farrowing interval with the number of piglets born alive and reared per litter, suggest that the native pig breeds should be bred in keeping with their breed predispositions.

The aim of the experiment was to assess the effects of supplemental lighting of cucumber grown in greenhouse using lamps with differentiated light spectra: sodium lamps – high-pressure sodium (HPS) and light emitting diodes (LEDs). Plants (cucumber ‘Pacto’ F1) were grown in two greenhouse compartments with five light treatments: I – HPS + LED (top light with HPS LEDs as interlighting), II – only HPS as top light, III – LED R (LED chips on board (COB) type with an increased level of red band), IV – LED W (LED COB type, white), V – LED B (LED COB type with an increased level of blue spectrum). Light treatments: HPS + LEDs and HPS were grown in one greenhouse compartment and the other three light treatments: LED R (red light supplementation), LED W (without additional supplementation) and LED B (red spectrum supplementation) in the second compartment in analogous climatic conditions. The LED lamps using COB technology are known to be a very efficient source of light. Plants were cultivated from December 2018 to March 2019 in mineral wool slabs Grotop Master (100 × 15 × 10) with four plants on one mat. They were illuminated for 18 h (from 5 am to 11 pm), setting the threshold value (on and off) at 130 W. The plants were drip-irrigated with a complete nutrient solution. The irrigation was controlled based on a weighting system. The assessment of the effect of lighting on early yield and quality of cucumbers was completed after 8 weeks of cropping. It was shown that it was possible to obtain 3.59 kg from one plant during the 8-week period of evaluation by illuminating plants with sodium lamps (HPS), while using HPS and LEDs as additional illuminated inter-rows 3.89 kg. The yield of plants illuminated by LED lamps varied depending on the variant of the spectrum used and was respective for LED R, LED W and LED B, 3.30 kg, 3.90 kg and 3.25 kg. The obtained results indicated that the yield of cucumber ‘Pacto’ F1 grown with HPS lamps at top lighting and at the same time using interlighting with LED lamps was similar to LED W lamps (i.e. without additional supplementation in the range of red (LED R) and blue (LED B) light). Due to good results of LED lamps (type COB for top lighting or as interlighting) used for the cucumber supplemental lighting and high energy efficiency of LEDs, the promising future for that type of lamps compared with traditionally used HPS during winter cultivation in a greenhouse was demonstrated.
The Effect of Eight Weeks of Sling-Based Training with Rotational Core Exercises on Ball Velocity in Female Team Handball Players
Authors: Dahl Kenneth , Tillaar Roland
Published: April 2021

The purpose of this study was to investigate whether sling-based training focused on rotational exercises would improve shooting performance in outfield handball players during the competitive season, and whether changes in performance were related to altered levels of core strength and rotational velocity. Twenty-five female outfield handball players (mean age 19.5 ± 2.0 years, height 1.72 ± 0.06 m, body mass 71.5 ± 8.6 kg, training experience 10.3 ± 2.4 years), performed 7 m shots, with and without a run-up, and jump shots. Maximal ball velocity, peak rotational velocity of the trunk with different loads and 1RM in a core strength test were measured before and after an 8-week training intervention. Players were divided into a sling-based and a plyometric/sprint training (control) group that trained three times per week for 8 weeks. The main findings were that sling-based training increased ball velocity by on average 3.2% across three techniques tested, while shooting performance decreased by 3% in the control group. However, both training groups demonstrated increased peak rotational velocity with different loads, but not the calculated 1RM core strength after the training period. It was concluded that sling-based training with rotational core exercises could improve maximal ball velocity in female handball players during a competitive season by around 3%. However, this increased ball velocity may have been caused by increased angular velocity in the core, rather than absolute maximal core strength. It is suggested that sling-based training has impacted timing variables of the different involved segments, or possibly power transfer between segments, which may explain the enhancement in ball velocity.
Assessing the Immediate Effect of Covid-19 Lockdown on Air Quality: A Case Study of Delhi, India
Authors: Sikarwar Ankit , Rani Ritu
Published: April 2021

In India, a nationwide lockdown due to COVID-19 has been implemented on 25 March 2020. The lockdown restrictions on more than 1.3 billion people have brought exceptional changes in the air quality all over the country. This study aims to analyze the levels of three major pollutants: particulate matter sized 2.5 μm (PM2.5) and 10 μm (PM10), and nitrogen dioxide (NO2) before and during the lockdown in Delhi, one of the world’s most polluted cities. The data for PM2.5, PM10, and NO2 concentrations are derived from 38 ground stations dispersed within the city. The spatial interpolation maps of pollutants for two times are generated using Inverse Distance Weighting (IDW) model. The results indicate decreasing levels of PM2.5, PM10, and NO2 concentrations in the city by 93%, 83%, and 70% from 25 February 2020 to 21 April 2020 respectively. It is found that one month before the lockdown the levels of air pollution in Delhi were critical and much higher than the guideline values set by the World Health Organization. The levels of air pollution became historically low after the lockdown. Considering the critically degraded air quality for decades and higher morbidity and mortality rate due to unhealthy air in Delhi, the improvement in air quality due to lockdown may result as a boon for the better health of the city’s population.

Gallium oxide β-Ga2O3 is an important wide-band gap semiconductor. In this study, we have calculated the formation energy and transition levels of oxygen vacancies in β-Ga2O3 crystal using the B3LYP hybrid exchange-correlation functional within the LCAO-DFT approach. The obtained electronic charge redistribution in perfect Ga2O3 shows notable covalency of the Ga-O bonds. The formation of the neutral oxygen vacancy in β-Ga2O3 leads to the presence of deep donor defects with quite low concentration. This is a clear reason why oxygen vacancies can be hardly responsible for n-type conductivity in β-Ga2O3.
