Authors: Putri Hana Tamara
Published: September 2023

The Theory of Capital Asset Pricing Model (CAPM) states that market risk (beta) can generate risk premium for investors. So investors only need to invest in a market portfolio or portfolio based on market capitalization weighting. Smart Beta portfolio is an index-based investment strategy that seeks to obtain superior risk-adjusted returns through transparent techniques and rules-based criteria based on specific factors or attributes that generate investment returns. Combining the Fama French Five Model, Variables Tracking Error and Active Share, this study proposes a Smart Beta model that will be selected from Issuers on the LQ 45 Index to 20 Issuers and compare which Return is better between IDX High Dividend Return 20 and Return from Issuer smart Beta portfolio results.

Published: September 2023

In recent years, the Tanah Datar district government has focused more on the physical implementation of irrigation area development and has not prioritized the budget for operating and maintenance costs so that there are still many Irrigation Areas (DI) whose irrigation infrastructure is not functioning properly with a high level of network damage that requires high costs. In addition, low awareness of the provision of operational and maintenance (OP) funds, limited human resources for OP staff, and the participation of groups of farmers using water (P3A) or a combination of groups of farmers using water (GP3A) is also not optimal. In order to function optimally and can be used for a long time, the irrigation that has been built needs to be maintained and managed systemically and to develop an optimal operating and maintenance management framework. The purpose of this study was to identify the dominant factors and factors that influence the operation and maintenance of irrigation networks in Tanah Datar District, as well as to optimize the operation and maintenance of the network. This study used a quantitative method by distributing questionnaires to respondents. The results of the research conducted revealed that there were 2 factors that influenced the operation and maintenance of irrigation networks in Tanah Datar Regency, namely the condition of physical infrastructure and supporting facilities and P3A Personnel Organization and Institutions..

As the population increases, the speed of population movement also increases and the availability of proper infrastructure in crowded centers decreases. One of the problems in terms of pedestrian facilities in Indonesia's urban areas is the lack of fulfillment of pedestrian needs, both in terms of quality and quantity. The development of pedestrian facilities in Indonesia has not become a priority comparable to the development of facilities for other modes of transportation. The lack of public understanding of pedestrian path facilities indicates the need for attention from the government in fulfilling the functional needs of pedestrian paths. Because of that it is important to understand the public's perception of the need for pedestrian facilities on Jalan Veteran Lamongan. Distribute questionnaires to the community and then carry out validity and reliability tests so as to produce public perceptions of pedestrian lane facilities on veteran roads, namely pedestrian paths, which need additional attention for facilities and infrastructure. 34% of respondents said there were many deficiencies in the quality of the sidewalks, then 31% said they lacked the quality of facilities for the disabled, then 33% of respondents said they lacked the quality of accessibility, then 31% of respondents felt they lacked the level of completeness of facilities, then 33% respondents said they lacked the level of safety, then as many as 36% of respondents felt they lacked the level of security, and finally 37% of respondents felt they lacked the level of satisfaction.
Monitoring the behavior of pigs as an indicator of assessing their health and welfare level

Published: September 2023

Ethological observation and behavioral monitoring are important indicators for assessing the state of health, determining the level of well-being, and predicting the productive qualities of animals in productive pig farming. An important factor is also the possibility of using behavioral indicators for early diagnosis and monitoring of the course of diseases in pigs of different ages and areas of use. Behavioral tests are used to evaluate the nervous system, reactivity, reproductive and technological qualities of animals. There are many types of behavioral tests. As a rule, the same tests can explain one or more aspects of an animal's behavior. it was established that the following tests are most often used to assess animal behavior: backtest, test for a new object, new environment, person, new animal, etc. One of the most common tests to determine the behavior of pigs is the backtest. It is used to determine the stress resistance of animals. To do this, the piglet is placed on its back for 60 seconds and the number of struggle attempts and its sound response are determined. As a result of the conducted test, piglets were divided into animals with high resistance and low resistance. According to the authors, the behavioral reaction of piglets during the backtest at the beginning of life can indicate the level of coping with stressful situations at an older age. Pig backtesting demonstrated a relationship between the degree of resistance that occurs early in life and a variety of behavioral and physiological responses in fattening pigs. The human test is used to assess aggressive and social behavior, to determine the animal's emotional state, in particular fear, as an instinct for self-preservation. The novel object test can be used to study search and exploratory behavior. The novel objects tested were a rope, a pile of soil, an experimental glove, a ball game, a rubber duck, and a pile of leaves. An important test parameter of the condition of pigs is the assessment of their playing activity. It is believed that, subjectively, play is an expression of the satisfied state of the animal. The study of animal behavior is an important tool for assessing the conditions of keeping and feeding, the level of well-being, and the cognitive-emotional state of animals. Appropriate use of behavioral tests also allows for the assessment and prediction of features of social behavior, reproductive status and potential productive qualities of an animal.

This article presents the research results on "Zolotokolosa" winter wheat variety sowing quality and its impact on field emergence, tillering coefficient, and productive tiller formation. The studies showed that it is quite challenging to adjust the seeder for accurate sowing rate, and the deviation over the three-year research period reached up to 5.1 %. The accuracy of seed burial depth with disc drills was relatively low, fluctuating around an average of 4.24, 4.6, and 4.3 cm compared to the planned depth of 4.5 cm. However, significant variation was observed within designated plots during the vegetation period of 2018–2019 (3.4–5.2 cm), 2019–2020 (3.5–5.9 cm), and 2020–2021 (3.4–5.3 cm). Field emergence depended significantly on weather conditions and soil moisture, being favorable in 2018 and 2019 with rates of 95.3 % and 94.1 %, respectively. However, the summer-autumn drought negatively affected field emergence in 2020, resulting in a lower rate of 85.5 % compared to previous years. The depth of tillering node burial during the research period ranged from 1.85 to 1.9 cm. More significant fluctuations were observed within designated plots during the vegetation period, ranging from 1.5 to 2.2 cm. The correlation coefficient between seed burial depth and tillering node burial depth was positive (r = 0.554, r = 0.095, r = 0.237). The coefficient of productive tillering showed slight variation over the years of research. During the vegetation period of 2018–2019, it averaged 1.56, while in the subsequent years it was 1.60 and 1.54, respectively. The highest number of productive tillers, exceeding the sowing rate of 5.5 million seeds per hectare, was formed during the 2019–2020 vegetation period, with an average of 717.6 tillers/m2 . However, there was significant variation in this value within the designated plots, ranging from 605 to 869 tillers/m2 or 84.3 % to 121.1 % of the average density. In the 2018–2019 vegetation period, the average number of productive tillers was 709.4/m2 , with fluctuations within the designated plots ranging from 588 to 869 tillers/m2 or 82.1 % to 122.5 % of the average density. The lowest number of productive stalks of wheat was recorded in 2020–2021, which can be attributed to a relatively dry autumn vegetation period. On average, there were 646.8 tillers/m2 . The density fluctuated the most within the designated plots that year, ranging from 499 to 863 tillers/m2 or 77.1 % to 133.4 % of the average density. The research methods employed included field observation, laboratory analysis, comparative analysis, data synthesis, and mathematical-statistical analysis.

Environmental protection aspects of corn mineral fertilizing on drained organic soils
Authors: Slyusar I. , Serbeniuk V. , Solyanyk O. , Serbeniuk G.
Published: September 2023

Based on the results of the research, the orientation of the processes of forming the optimal nutrient regime on drained organic soils under corn for grain was determined by establishing scientifcally based doses of mineral fertilizers, depending on the methods that take into account the characteristics of these soils and methodological approaches to determine the doses of mineral fertilizers in the conditions of feld stationary experiment on drained organic soils of the ﬂoodplain of the Supii River. It was established that the application of mineral fertilizers leads to the strengthening of mineralization processes, which rises with increasing doses of fertilizers, which, in turn, leads to the accumulation of nutrients that affect the yield of cultivated crops and their migration into drainage waters. The increase in the content of nitrogen (N-NO3, N-НН4) and phosphorus (P2O5) compounds in drained organic soil are caused by both organic matter mineralization and mixing of vivianite and freshwater shells layers with peat soil, which causes an intensive oxidation process in the combined with CaСО 3 compounds, and as a result, organic matter decomposes into a partially humic complex of organic and mineral substances. Available for corn consumption nutrients further accumulate in the soil. The highest yield of corn per grain (8.34 t/ha) was obtained with the application of fertilizer doses based on the data of long-term studies (P45K120 with the addition of 2.0 l/ha of the combined preparation with the growth stimulator "Organic Balance"). The introduction of such doses of mineral fertilizers provides the greatest increase in yield per unit of applied fertilizers, and their leaching into drainage waters did not exceed the maximum permissible concentrations of water management objects for economic and cultural and domestic use. The use of justifed doses of fertilizers in corn crops ensures the highest yield with cost-eﬀective costs per unit of production. It also takes into account the environmental aspects of mineral fertilizers, which prevent excessive leaching of biogenic substances into drainage waters, and, as a result, reduces the pollution of river waters.

Toimintatutkimuksella ilmiölähtöisyyttä ja sidosryhmäymmärrystä lainoppiin – havaintoja lainopin ja matkailututkimuksen välisestä vuoropuhelusta
Authors: Päläs Jenna , Hakkarainen Maria
Published: September 2023

Alustavälitteinen palveluiden tuottamisen yleistyminen ja toimijakentän monipuolistuminen edellyttävät tietoa siitä, miten  jakamistalouspohjaisen matkailun vastuullisuutta voidaan ohjata ja säännellä. Ilmiöön kiinnittyvän vastuullisuuden ymmärtäminen kuitenkin edellyttää, että ilmiön rakenteita tarkastellaan laajemmissa kokonaisuuksissa, eri käsitejärjestelmien ja tieteenalojen vuorovaikutuksessa. Kirjoituksemme keskittyy oikeustieteiden alle lukeutuvan lainopin ja matkailututkimuksen vuoropuhelun tarkasteluun ja pohdimme kuinka toimintatutkimusmenetelmä voi toimia poikkitieteellisen tutkimuksen mahdollistajana. Reflektoimme Vastuullisuus ja arvonluonti jakamistaloudessa (Jaava) -hankkeessa toteutettua tutkimusprosessia ja pohdimme, miten toimintatutkimus rikastutti aineistoa, tuotti näkökulmia poikkitieteellisille havainnoille ja mahdollisti ilmiöymmärryksen lisäämisen.
Havaintojemme mukaan tieteenaloja yhdistävä toimintatutkimus näyttäytyy väylänä välittää lainopillisia havaintoja matkailututkimuksen kohteena olevasta ilmiöstä ja tuottaa poikkitieteellistä ymmärrystä toimija- ja sidosryhmätutkimukseen. Lainopillinen tieto normi- ja tulkintaympäristöstä tekee näkyväksi yhteyksiä, joiden ansiosta matkailun vastuullisuustutkimus ikään kuin saavuttaa uusia toimijoita, oikeusjärjestyksestä ponnistavissa yhteyksissä, tutkimussuuntausten ja tieteenalojen katvealueita ylittäen. Lainopille toimintatutkimus tuottaa tietoa sidosryhmälähtöisesti oikeuden normatiivisesta vaikutuskentästä, oikeussäännösten tulkinta-asetelman vaikutuskontekstista ja sen subjekteista. Toimintatutkimus voi edistää oikeustilan epäselvyyksien tarkempaa erittelyä eli auttaa vastaamaan kysymykseen, mistä oikeustilan koetussa epäselvyydessä on oikeastaan kysymys. Tuotettu kontekstiymmärrys tarjoaa mahdollisuuksia myös lain- ja oikeusanalogiaan perustuvalle argumentaatiolle. Tieteenalojen välisen vuorovaikutuksen rinnalla tutkimus tuotti tietoa ja konkreettisia toimintaohjeita matkailualan vastuullisuustyöhön.
Matkailuyrityksen vakuuttava vastuullisuusviestintä
Authors: Pasanen Katja , Konu Henna , Koponen Jonna
Published: September 2023

Kiinnostus vastuullisia matkailupalveluita kohtaan on kasvanut viime vuosina, mutta tietoa vastuullisista palveluista ei ole tarpeeksi saatavilla tai yrittäjät eivät osaa viestiä niistä siten, että viestit vetoaisivat tavalliseen kuluttajaan. Aiemmissa matkailualan tutkimuksissa ei ole selvitetty retoriikan merkitystä osana vastuullisuusviestintää. Lisäksi matkailuyrityksen viestinnän vastuullisuussisällöistä puuttuu tietoa holistisesta näkökulmasta. Tämä tutkimus tarkastelee, mitkä Aristoteleen Retoriikan eli vakuuttavan viestinnän keinot (ethos, pathos, logos) yhdistettynä eri vastuullisuusviestinnän vastuullisuussisältöihin vetoavat suomalaisiin kuluttajiin maaseutumatkailuyrityksen vastuullisuusviestinnässä. Tutkimuksen aineisto kerättiin hyödyntäen kaupallista kuluttajapaneelia ja tutkimukseen osallistui kaikkiaan 515 henkilöä. Tutkimuksen tulosten mukaan suomalaisiin kuluttajiin vetoaa matkailuyrityksen vastuullisuusviestinnässä erityisesti yrityksen uskottavuuteen vetoaminen sekä useiden vakuuttavan viestinnän keinojen samanaikainen käyttö. Kuluttajiin eniten vetoavina sisältöinä tutkimuksessa nousi esiin helposti lähestyttävät ja kuluttajille tutut ekologiseen, taloudelliseen ja kulttuuriseen vastuullisuuteen liittyvät sisällöt. Tämä tutkimus tuottaa uutta tietoa matkailualan vastuullisuusviestinnän keskusteluun yhdistämällä vastuullisuussisällöt erilaisiin vakuuttavan viestinnän keinoihin sekä hyödyntämällä aiemmin lähinnä viestintätieteiden kontekstissa käytettyä Aristoteleen Retoriikkaa teoreettisena viitekehyksenä matkailumarkkinoinnin tutkimuksessa. Tutkimus auttaa myös matkailualan yrityksiä kehittämään omaa vastuullisuusviestintäänsä.

It is claimed that sport is an influential mechanism that could withstand against a great many negativities with regard to life for disabled people. To this end, the purpose of the current study was to investigate the relationship between the acceptance of disability and resilience levels of athletes and non-athletes. The group of the research was made up of 140 athletes and 165 non-athletes (90 female, 215 male). In this study, which was designed in a descriptive research model, Acceptance Disability Scale (ADS) and Connor-Davidson Resilience Scale (CD-RISC) were used as the data collection tools. It was found that both the acceptance of disability and the resilience levels of athletes were high compared to disabled ones and that there was a significant difference (p<0.01). In addition, it has been understood that the average scores of individuals who are successful in international competitions are higher than those who are successful in national competitions. It was concluded that there is a good level of positive relationship between acceptance of disability and resilience levels. As a result, the sport seemed to affect both acceptance of disability and resilience significantly.

Influence of different oxygen modes on the blood oxygen transport and prooxidant-antioxidant status during hepatic ischemia/reperfusion.
Authors: Zinchuk VV , Khodosovsky MN , Maslakov DA
Published: September 2023

Oxygen supply was corrected in rabbits during the hepatic ischemia/reperfusion by means of different breathing mixtures: hypoxic (14.8 % O2+85.2 % N2), hyperoxic (78 % O2+20.2 % N2+ 1.8 % CO2), or hypercapnic (5 % CO2 in air). Hepatic ischemia was induced for 30 min by ligation of hepatic artery, reperfusion period lasted 120 min. Indices of blood oxygen transport (p50act, pCO2, pH, pO2, etc.) and prooxidant-antioxidant balance (Schiff bases, conjugated dienes, catalase, retinol, a-tocopherol) were measured in the blood and liver. The severity of reperfusion damage was evaluated by the activities of alanine and aspartate aminotransferases (ALT, AST) in the blood. Hepatic ischemia/reperfusion resulted in higher p50act in hepatic venous and mixed venous blood in all experimental groups. The changes of p50act were most marked in the hypercapnic group and were the weakest in the hypoxic group. The rise in p50act was accompanied by higher levels of lipid peroxidation products, ALT and AST in blood and liver homogenates, and by a simultaneous fall of -tocopherol and retinol concentrations, except in the hypoxic group. Catalase activity at the end of reperfusion increased under normoxia, decreased under hyperoxia or hypercapnia and did not change under hypoxia. The moderate hypoxia during reperfusion was accompanied by a better balance between the mechanisms of reactive oxygen species production and inactivation that may be observed by optimal changes in p50act and reduced the hepatic damage in this pathological condition.

Resveratrol, which is a polyphenol present in red wines and vegetables included in human diets, exerts many biological effects. The aim of the present study was to investigate its effect on some activities of polymorphonuclear leukocytes, particularly the generation of superoxide anion (O2-) in whole blood, hypochlorous acid (HOCl) and nitric oxide (NO) production by isolated cells, and chemotaxis. Resveratrol showed significant dose-dependent inhibitory effect on all these activities. In particular, it inhibited O2- generation in stimulated but not in resting neutrophils, decreased HOCl much more than O2- production indicating an effect on myeloperoxidase secretion since HOCl production is directly and proportionally dependent on O2- generation and reduced cell motility. The small dose of resveratrol (4.38 nM) used is attainable with a diet including red wine and vegetables confirming its protective role against some pathological processes such as inflammation, coronary heart disease, and cancer.
Subcellular targets of mercaptoborate (BSH), a carrier of 10B for neutron capture therapy (BNCT) of brain tumors.

The transformed C6 glial cells in cultures were treated with sodium mercaptoborate (Na2B12H11SH, BSH), a carrier of atomic targets (10B) of thermal neutrons for the neutron capture therapy of brain tumors. As shown by light microscopy, the therapeutic dose of BSH (100 µg/ml) did not alter the gross morphology and growth of the population of cells within a 72 h treatment interval. Electron microscopic analysis of these cells revealed activation of nucleoli and, occasionally, enlarged and bifurcated mitochondria. After 200 µg BSH/ml and 72 h treatment, growth of the cell population was inhibited and ultrastructural changes became more profound. They included condensation of chromatin and its allocation to the nuclear envelope which formed deeper invaginations. Mitochondria further increased in size and were characterized by slim or angular cristae. Moreover, in circumscribed segments of some of the slightly swollen mitochondria their cristae disappeared or were reduced to fine pouch-like structures localized near the continuous outer membrane, suggestive for a non-destructive restructuring of the inner mitochondrial membrane. The smooth pinocytotic vesicles near the plasma membrane, lysosomes and heterogeneous dense bodies were more frequent. The revealed subcellular targets of BSH may initiate the development of pharmacological protocols aimed to further improve the tolerance to BSH by the healthy tissues of patients undergoing BNCT of brain tumors, e.g. by intervention into the oxidative stress triggered likely by the altered mitochondria.

GPS (Global Positioning System) information is a type of EXIF (Exchangeable Image file Format) metadata that's implanted in a computerized photo record. The project aims to create a system that takes useruploaded pictures, extracts the metadata, shows the coordinates of the location information on a custom Google Maps embedded API, and displays the make and model of the gadget utilized to capture the picture. The system employs Python's exif and Pillow modules to extract the metadata from the uploaded image file. The metadata incorporates GPS information that contains the latitude and longitude coordinates of the area where the picture was taken. The extracted coordinates are then passed to the Google Maps API to show the area of the picture on map. This data is shown on the webpage, giving extra subtle elements almost the picture.

Published: September 2023

Sign language detection plays a crucial role in bridging the communication gap between individuals with hearing impairments and the rest of the population. This study presents a novel approach for sign language detection using action recognition and LSTM deep learning models implemented in Python. The proposed system aims to accurately recognize and interpret sign language gestures in real-time. The research focuses on leveraging the power of deep learning techniques, specifically the Long Short-Term Memory (LSTM) architecture, to effectively capture temporal dependencies and classify sign language gestures. A comprehensive dataset comprising a wide range of sign language gestures is collected and preprocessed to train and evaluate the LSTM model. The pipeline for sign language detection consists of several stages, including video acquisition, preprocessing, feature extraction, and model training. In the pre-processing stage, the acquired video data is segmented into individual frames, and various image processing techniques are applied to enhance the quality and remove noise. Next, robust features are extracted from the preprocessed frames using techniques like optical flow or deep learning-based feature extraction methods. The LSTM model is then trained on the extracted features to learn the temporal dynamics of sign language gestures. Transfer learning is also explored to leverage pre-trained models on large-scale action recognition datasets. The trained model is evaluated using a comprehensive set of metrics, including accuracy, precision, recall, and F1-score, to assess its performance. Experimental results demonstrate the effectiveness of the proposed approach in accurately recognizing sign language gestures. The LSTM-based deep learning model achieves a high accuracy rate, showcasing its capability to handle the temporal nature of sign language. The system exhibits real-time performance, enabling it to be deployed in various applications, such as real-time interpretation tools or assistive devices for individuals with hearing impairments

Published: September 2023

The present paper highlights several concerns with solar-wind hybrid energy systems that are associated with microgrids as well as potential improvements. In recent years, there have been more renewable energy options available. Alternatives to the present energy sources, such as renewable energy, are very good. The utilization of renewable energy sources like solar and wind power as a consistent energy source is widespread. The focus of this study is on microgrid connected solar-wind hybrid energy system performance analysis and control. In this paper, the harmonics of the system are controlled by passive filters. Additionally, several control topologies based on power electronics control are needed for the micro grid’s integration of various energy sources. A power electronics application is used in microgrids that use a variety of renewable energy sources, however some power quality problems frequently arise. The whole microgrid system's voltage management and voltage stability must be maintained, therefore these power quality issues must be fixed or at the very least reduced. An example of a solar-wind hybrid power system simulation using MATLAB is provided in this study. For micro-grid parameter adjustments, PI-PWM control is included into the MATLAB microgrid simulation. The outcomes of the simulation show that the present THD levels in the grid are less than 5%. The energy storage system also serves as a backup power source in this simulation for power variations brought on by irregular solar and wind power generation in the microgrid.
