Published: June 2023

The performance of a newly developed pilot scale continuous enzymatic deinking system has been evaluated using a mixture of cellulase and xylanase enzymes in the deinking of mixed office wastepaper (MOW) and old newspaper (ONP). Optimizations of the enzymatic deinking processes were carried out, and the optimum conditions obtained for MOW and ONP were different. The highest brightness obtained from enzymatic deinking of MOW and ONP under their respective optimum conditions were about 83.6% and 41.9%, respectively. The deinking efficiency of 6.0% and 6.3% were obtained by enzymatic deinking process using MOW and ONP, respectively. On the other hand, the deinking efficiency of 2.9% and 3.5% were obtained by a chemical deinking process using MOW and ONP, respectively. The findings obtained from present work indicated that enzymes have potential to be used in deinking of MOW, which is difficult to deink by conventional chemical deinking methods.

Published: June 2023

Abstract: Oil and gas-producing countries are suffering from water resource depletion without any treatment or with technologies that have the same impact, regardless of how expensive or large a land area required. On the other hand, domestic wastewater also has many treatment technologies, and biological full cell is one of them. Using an end-of-tube hollow fiber membrane in domestic wastewater allows biological microorganisms to grout and treat the water, whereas using oil-filled water has not been studied so far. This study addresses the potential of biological growth on two different types of dead-end hollow fiber membranes by using three samples of oilfield water i.e., Membrane Aerated Biofilm Reactor OxyMem and MEMCOR® Ultrafiltration. The Membrane Bioreactor Systems are selected for the current studies and scanning electron microscopy (SEM) is used to show the biological growth on selected types of membrane to treat the oilfield wastewater. As a result, the growth in OxyMem is better which is 54% of COD removal and 55% NT removal for 55 days, whereas MEMCOR shows comparatively less growth in SEM results with 33% of COD removal and 9% NT removal during the same period. Therefore, this confirms that both types of membranes can be used to treat oilfield water in biological cells and noticed a better performance in OxyMem compared to MEMCOR.

Published: June 2023

The vitreous humor was examined using LED, one of the non-invasive techniques. An acute-angle flare-out-blasting status with continuous broaden conversion was confirmed by irradiating a certain amount of LED on a round hemisphere. It was judged that twinkle-disparity cognition level (TDCL) was formed by several broaden cognition functions of the scattered signal generated for a few seconds from the irradiated LED. Flare-out-blasting was configured as a system according to the level of cognition, and a rugged conveyance technique was used to confirm the experimental conditions of the twinkle tactile-dot. The degree of scattering caused by the surrounding micro-vessels and foreign substances in the vitreous humor was different according to the tactile-dot level. The maximum average value formed in the flare-out-blasting status was calculated as the result value as a result of the acutely converted output of the TDCL. Broaden tactile-dot blasting presented broaden far transition value of Br-CF-FA-?MAX-AVG with 8.49±(-0.22) units. Broaden convenient transition value presented Br-CF-CO-?MAX-AVG with 2.08±(-0.84) units. Broaden flank transition value presented Br-CF-BR-?MAX-AVG with 1.03±(-0.35) units. Broaden vicinage transition value presented Br-CF-VI-?MAX-AVG with 0.16±(-0.02) units. TDCL formed in the flare-out-blasting status expanded the cognition level to form a tactile-dot. The ability of the broaden cognition function to be scattered according to the acute-angle in the flare-out-blasting function was evaluated. It was confirmed that the twinkle-disparity function necessary for the cognition level system appeared by using a rugged conveyance to examine the vitreous humor with a non-invasive rugged conveyance technique. These physical findings made it possible to characterize broaden cognition function in vitreous humor and laid the based on utilizing flare-out-blasting level data by the flare-out cognition system.

Authors: Lim Soo-Hee, , Kong Ha-Sung,
Published: June 2023

The aims of this study is to comparative analyze the flame resistant of Larix kamperi according to fire retardant paints with different main components. Wood, an eco friendly traditional material, has been proven to reduce carbon, drawing attention as a solution to climate change, an international environmental issue. Wood is used as a material for buildings as furniture, interior, and furniture, and greatly satisfied users who require eco-friendliness. However, wood is a factor that increases the fire load in a fire. In previous studies, the fire vulnerability of Cryptomeria japonica, Pinus densiflora, MDF, OSB, cork board, and plain wood plywood was analyzed. As a result, wood without flame retardant treatment was vulnerable to fire. To compensate for this problem, we intend to secure an evacuation time by delaying the ignition time in case of a fire. Accordingly, Flame retardant treatment is implemented in accordance with Article 20 of ?the Enforcement Decree of the Act on the maintenance and Safety Management of Firefighting Facilities?. The main flame-retardant paint used is bromine, a halogen compound, and has high flame resistant. However, it is subject to environmental regulations due to the problem of soot and smoke generation. Eco friendly fire retardant paint are continuously being developed to escape regulations. Therefore, it is necessary to measure the effect of the flame resistant by treating the developed fire retardant paint for each tree species. So, three types of fire retardant paint with different main components are selected and treated on a larch plywood to analyze flame resistant. In this study, after flame time, after glow time, char length, and char area were measured in accordance with Standard of the Nation Fire Agency of Republic Korea. The main components of fire retardant paint are ammonium polyphosphate, emulsion resin, and phosphorus based mixture. Based on each theoretical application amount, 150g/m2, 180g/m2, and 180g/m2 were applied as the flame retardant paint. As a control group, a test specimen that was not with flame retardant treatment was set. The results are as follows. First, ammonium polyphosphate was the most excellent flame resistant. Second, as a result of flame retardant treatment the phosphorus mixture with the same main ingredient on the same type of larch plywood, the effect of flame resistant was different depending on the technology development of each manufacturer. Third, all larch plywood satisfied the flame resistant regardless of the presence or absence of flame retardant treatment. This seems to be because Larix Kamperi itself has a property that does not burn easily. It is expected that the results of this study will be used as basic data for the production of semi noncombustible material suitable for flame resistant Standard of the Nation Fire Agency of Republic Korea in the future.

Published: June 2023

The entry into an ultra-old society in South Korea, the remarkable development of medical technology as well as the recent emergence of the Fourth Industrial Revolution have contributed to the steady growth of the silver industry in line with the demand for healthy lives of the elderly. However, the silver industry of South Korea is still a rudimentary level. The existing older telecare product was sensor-based and was able to respond at or after the accident. However, there are limitations in preventing and predicting accidents. In particular, preventive healthcare is very important because even in small accidents, older people can be at great risk. We intend to build a healthcare platform based on IoT, against this backdrop. Based on previous studies, we try to build a new concept of architecture by collecting, storing and analyzing data to overcome the limitations of existing platforms. It’s supposed to build cloud-based Bigdata storage that can collect and analyze real-time operating conditions for older people with cameras and mobile phones, and study algorithms for old-age care through Artificial Intelligence. This research would certainly give more safe accident prevention and health care for the elderly and the healthcare industry.

Consumer Responses to Multi-Promotion Offering: The Moderating Impact of Regulatory Orientation
Authors: Kim Moon-Yong
Published: June 2023

Among the various promotional tools, bonus packs and price discounts have been found to be the most effective and have thus attracted the most attention from researchers. This research primarily focuses on multi-promotion offers containing both a bonus pack and a price discount (i.e., BP + PD offers). The present research aims to examine the moderating role of consumers’ regulatory orientation in their responses to BP + PD offers. That is, this research investigates whether consumers’ attitude toward the BP + PD offers and their purchase intention differ according to their regulatory orientation (promotion orientation vs. prevention orientation). Specifically, it is predicted that consumers with a prevention orientation, as compared to those with a promotion orientation, will have more favorable attitude toward the offers containing the high PD but low extra amount of BP (i.e., HPD LBP offers) than the offers containing a high extra amount of BP but low PD (HBP LPD offers) (hypothesis 1) and higher product purchase intention in the HPD LBP offers (hypothesis 2). An experiment was conducted to test the hypotheses. Consistent with the hypotheses, it was found that participants’ regulatory orientation moderates their responses to multi-promotion offering.
A Study on the Effects of Firefighters' Job Autonomy and Job Satisfaction on Organizational Commitment
Authors: Choi Bok-Mu, , Kong Ha-Sung,
Published: June 2023

This study empirically analyzed the effects of job autonomy and job satisfaction on organizational commitment of firefighters performing the current standard daily routine for firefighters, and aimed to provide basic data for standard days and improvements that reflect the working environment and dispatch characteristics. It is unreasonable to uniformly apply the current standard routine to the unpredictable dispatch environment of firefighters. As a result of analyzing a sample of firefighters nationwide, it was found that the current standard work and performance hindered job autonomy and job satisfaction. As a result of empirical analysis with job autonomy and job satisfaction as independent variables and organizational commitment as a dependent variable, it had a positive (+) effect. Therefore, the results of this study suggest that there is a need to increase organizational commitment through the current standard work and improvement of firefighters. However, there is a limitation in that research does not reflect all matters such as differences in work patterns by region, characteristics of dispatch by region, and characteristics by position, and it should be improved into a standard routine that can be commonly applied to firefighters nationwide through future research.

Published: June 2023

This study was conducted to determine the effect of Otago exercise intervention on muscle mass, muscle strength, and physical performance, which are diagnostic indicators of sarcopenia, in elderly individuals aged 65 or older. The final subjects included 6 individuals in the walking exercise group and 5 people in the Otago exercise group. Walking exercises were conducted 12 times a week for 22 minutes at a time and more than 80 steps per minute whereas the Otago exercise was conducted four times a week for 50 minutes, a total of 12 times under the supervision of a senior movement leader. After the intervention, a diagnostic evaluation of sarcopenia was performed, and before and after the intervention, the intergroup skeletal muscle mass (ASM), grip force (Hand Grip), and SPPB were compared. The three evaluation parameters are related to physical function and showed that after each exercise intervention, the Otago exercise group exhibited an increase in the limb skeletal muscle and the SMI. The walking exercise resulted in a decrease in muscle strength, but the Otago exercise group showed an increase in this metric. The SPPB score increased in the Otago movement group, but no statistically significant results were obtained. It was demonstrated that the Otago exercise positively affects the index of muscle loss in the elderly, and is potentially effective for preventing and managing sarcopenia.

Determination of effective seismic wave velocities using time gradients obtained from response and CDP reflection hodographs
Authors: TR Akhmedov , Yimear Turehan
Published: June 2023

Seismic wave velocities, including effective velocities, play a critical role in the kinematic processing and interpretation of 2D and 3D seismic data. Along with other parameters of elastic waves, the geological efficiency of seismic exploration also depends on the level of knowledge of the velocity model of the medium, on the accuracy of information about velocities. The article briefly lists the main methods for determining the effective velocities according to the seismic wave field, developed and applied in the practice of seismic research. The methods used to determine the effective velocities of reflected waves can be divided into two groups: methods for determining the effective velocities based on automatic or visual tracking of the in-phase axes (i.e. hodographs) of reflected waves on seismic records, then their approximation by hyperbolas constitute the first group, and the second the group consists of methods based on the application of the analysis of the seismic wave field in controlled directions on the seismograms of a common depth point (CDP). Each proposed method for determining effective speeds has advantages and disadvantages. The article focuses on the industrial method, widely used at present, based on the analysis of the wave field in controlled directions, which do not provide sufficient information to solve the main problems of kinematic interpretation. The main disadvantages of the existing methods are indicated. The article describes a new method for determining the effective velocity, which is fundamentally different from the methods that are still used in the practice of seismic exploration. The fact is that in this method, seismic survey data of single and multiple profiling are not used separately, as it was in the methods used in seismic survey practice so far, but together. Formulas have been derived for determining the effective velocity based on the time gradients of the travel time curves of the CSP and CDP of reflected waves, which makes it possible to determine the speeds even from incomplete travel time curves. A technique for determining the effective speed has been developed and a sequence of procedures has been determined for solving the problem. The results of research are given on a specific example by solving the direct and inverse problems for the Sazhdag area between the Kura and Gabyrra rivers. The influence of errors in the values of the parameters included in the formula for calculating the effective speed on the final results is studied. At the end of the article, the main advantages of the proposed method are indicated.

Purpose: To evaluate and compare the ocular blood flow in non-glaucoma versus primary open-angle glaucoma (POAG) subjects attending the ophthalmic clinic of University of Nigeria Teaching Hospital (UNTH) Enugu using Doppler ultrasonography. Methods: A cross-sectional comparative study was adopted. Fifty-Eight POAG and 58 non-glaucoma subjects were recruited. Information on their socio-demographic and clinical profiles was obtained via an interviewer-administered questionnaire. Ocular Doppler Imaging was performed on all the Subjects. Peak systolic volume, End diastolic volume, mean flow velocity and Resistive Index (RI) of the central retinal artery and ophthalmic artery were recorded. Data were analysed using the SPSS version 21. Person correlation was used to determine the relationship between the Doppler indices and demographic and clinical variables. The level of significance was at p <0.05. Results: The subjects were mainly males, 71(61.7%), with an age range of 40 to 79 years. The POAG Subjects lived with glaucoma for 5.57±4.2 years, and mainly on medical treatment 52(89.7%) with beta-blockers and prostaglandin analogues. The RI was significantly higher (p=0.01) in POAG subjects. A significant positive relationship (P = 0.014) was observed between RI and intraocular pressure (IOP) of the POAG subjects. Conclusion: In POAG subjects, RI was significantly higher; as the IOP increased there was an increase in RI translating to a sub-optimal ocular blood flow. Interventions aimed at modifying the RI would therefore be synergistic with IOP lowering measures. Additionally, RI assessment may offer a new target for glaucoma case finding.

In soils of arid and semi-arid regions, nitrogen constitutes one of the most critical elements for plant nutrition. This makes it essential to look for mechanisms or tools that allow improving the nutrition of species of economic importance, without harming the environment. It is known that numerous species of bacteria participate in the biogeochemical cycle of nitrogen and promote its movement through the soil-plant system, thereby acquiring great relevance in plant nutrition. There are numerous antecedents of the response of alfalfa to inoculation with symbiotic fixing bacteria of atmospheric nitrogen, and this knowledge takes on greater importance in the organic production of this crop. The objective of the work was to isolate symbiotic fixing bacteria from atmospheric N2 in alfalfa cultivated in the central Valley of the province of Catamarca, to be used as potential biofertilizers. In a plot of sandy loam soil with little nitrogen availability and no inoculation history in more than 40 years, a random sampling of 60-day alfalfa plants (type RR) with spontaneous nodulation was carried out. The presence of nodules was observed and from them the isolations were made in YEMA culture medium, incubating at 28°C and their cultural characteristics were determined. The preliminary results indicate that in the initial physiological states of the legume the existence of nodules, which manifests the presence of native rhizosphere colonizing rhizobia and with high competitiveness in infection. The cultural characteristics of the isolates obtained show the variability of nodular strains, creamy, fluid, translucent, pink, white colonies were observed, with development times between 24 and 48 hours of rapid growth. Conclusion: Medicago sativa may nodule with rhizobia native to the Central Valley area of ​​the Province of Catamarca, given its compatibility and ecological and biological adaptation, a desirable aspect in the future selection of strains. Knowledge of these symbiotic relationships will allow their integration with other production practices and the development of environmentally safe management techniques, seeking to maximize the productive efficiency of crops

From a broad perspective, the author, on the basis of an ethnographic study in a natural context, develops the concepts of cultivated growth and natural growth, relating them to social class and highlighting the effects of each one on the relationship between family and school. On this basis, it is understood that, despite the changes in social and family life brought about by contemporaneity, the role and weight of social class in the unfolding of family, school and social life is a catalyst of the social differences currently observed in the world.
A critical analysis of reproductive health challenges of Cameroonian female refugees in Nigeria
Authors: Forsac-Tata Dorothy
Published: June 2023

The difficulties faced by refugees cannot be over emphasized. After losing their homes and livelihood, they become vulnerable to hunger and face multiple challenges in the host countries. As such, their health are often compromised due to disruption of traditional health systems and an increase in risk factors.1 For women, their reproductive health challenges are compounded because of gender specific issues. These challenges are multifaceted and sometimes with severe consequences on their health. This paper reviews the reproductive health challenges of female refugees and how they affect the health of Cameroonian female refugees in the Adagom refugee camp in Nigeria. The study population consist of all female refugees of reproductive age (15-49) at the three Adagom refugee camps (Adagom 1, Adagom 2 known as Ukende and Adagom 3). Those considered were also those who had a registered status under the UNHCR. Informed by both the Andersen’s Behavioral Model of Health Centre Use and the People-Oriented Planning Framework, the study samples one hundred and twenty (120) Cameroonian refugee women from the three camps using the snowball method until saturation. Findings revealed that women faced enormous challenges with their reproductive health and these included poverty, distance, lack of knowledge, attitudes of health service providers, lack of support, violence, rape, and other unsafe practices. These challenges have multiple effects on women’s health including unwanted pregnancy, unsafe abortions, pregnancy complications (eclampsia and pre-eclampsia), infections, inability to conceive, stress and trauma, miscarriages and even death. It will therefore be imperative that reproductive health services be an integral part of refugee health package so as to reduce these effects on women’s health.
The mural paintings of Modest Sosenko. Characteristics of the style based on representative examples.
Authors:   The Andrey Sheptytsky National Museum in Lviv, Semchyshyn-Huzner Olesia
Published: June 2023

In the considerable creative legacy of the Ukrainian artist Modest Sosenko (1875–1920), the murals and sacred easel paintings he created for more than ten Galician churches deserve special attention. His contemporaries noted that the artist’s sacred works were characterised by his own ‘Sosenko style’, which boldly and organically combined Byzantine traditions reinterpreted by 16 th – and 17 th – century masters with modern European stylistic requirements of the turn of the 19 th and 20 th centuries. He was a pioneer who paved the way for the development of modern church art, which was helped by the circumstances of his life. After acquiring a thorough European professional education during his studies in Kraków as well as in Munich and Paris thanks to a scholarship funded by Metropolitan Andrey Sheptytsky, Sosenko returned to Galicia and, continuing his mentor’s activities in the field of museums, became a full-time employee of the Church (later National) Museum. His direct contact with old monuments of iconography, manuscripts and incunabula, and folk art allowed him to gain a deep understanding of the peculiarities of Ukrainian national art. Thus, the combination of his personal talent, professional knowledge and museum experience, as well as his close relationship with the head of the Greek Catholic Church – Andrey Sheptytsky, who directed all his efforts towards the revival of the high culture of decorating the sacred space of Eastern Rite churches, gave birth to an intellectual artist, ready to take up the challenge of the present day. However, it is not possible to appreciate Sosenko’s achievements in their entirety. The warfare in the region during the two world wars of the 20 th century, the years of Soviet rule, which was intolerant of cultural, national and spiritual heritage, and even the first years of Ukrainian independence, were not conducive to the preservation of the churches and their decoration. As a result, researchers are forced to conclude that most of Sosenko’s works have been irretrievably lost. The artist’s sources of inspiration, the specific composition of his monumental artworks, the range of colours, the ideological and aesthetic programme can only be reconstructed on the basis of the decorations of two churches in the Lviv region: St. Michael the Archangel in the village of Pidberizci and the Holy Resurrection in the village of Poliany, by making comparisons with fragments of lost murals recorded in archival photographs, and by adding the decoration, already after restoration toning, of the artist’s last sacred object – St. Nicholas Church in Zolochiv. Even such scattered data make it possible to observe many of the author’s characteristics, to determine the process of the formation of Sosenko’s distinct individual artistic style, to which this study is dedicated.

O presente artigo tem como objetivo discorrer sobre duas experiências de ensino realizadas com turmas do Ensino Médio de um curso técnico na modalidade integrada. As atividades aqui descritas ensejam romper com um tipo de organização curricular tradicional das áreas do conhecimento, dessa forma, procurando articular uma visão mais abrangente e total do conhecimento aos alunos envolvidos. Para isso, o texto, também, propõe-se a discutir a concepção de currículo integrado, como proposta que requer o abandono da memorização e do ensino descolado da realidade social, ou seja, centrada nas vivências do aluno que, portanto, não mais será mero receptor, e, sim, construtor do conhecimento.
Interdisciplinaridade e ensino de Física em cursos técnicos de Ensino Médio Integrado por meio de Teias de Conhecimento
Authors: Souza Danilo Almeida
Published: June 2023

O objetivo deste artigo é discutir a interdisciplinaridade no ensino de Física na EPT a partir da experiência de Teias de Conhecimento aplicada no período de Atividades de Ensino Não Presenciais Emergenciais (AENPE) do Instituto Federal da Bahia campus Ilhéus. A pesquisa é de natureza qualitativa e parte da análise de três planos de AENPE pensadas para o público do Ensino Médio Integrado (EMI). Os dados revelam que o tratamento interdisciplinar da Física não aparece de forma explícita para todos os planos analisados. Apesar disso, identificamos elementos que estavam ausentes em estudos anteriores que avaliaram cursos de EMI, no contexto do ensino presencial. Dessa forma, a experiência das Teias pode representar uma travessia de um currículo disciplinar para um currículo efetivamente integrado.

Nesse contexto, o presente artigo tem como objetivo refletir sobre a necessidade de reorganização do ensino e do reflexo nos resultados de permanência e êxito dos estudantes nos Cursos Técnicos Integrados, a partir da estratégia de distribuição de disciplinas em ciclos. Essa proposta foi elaborada após diálogo constante com estudantes, familiares e docentes pelo Setor de Assessoria Pedagógica. Como resultado, é possível observar que foi positiva essa organização, favorecendo a qualidade do trabalho docente e promovendo a motivação para os estudantes seguirem os seus estudos e alcançarem o êxito ao final do ano letivo de 2020.
O Cinema vai até o Esporte:
Authors: Luz Junior Almir Ferreira
Published: June 2023

Esse artigo relata uma experiência de ensino nas aulas de educação física para estudantes do 2º ano de cursos técnicos integrados ao ensino médio. O tema de ensino é a história do esporte e a atividade se dividiu em três etapas: desenvolvimento do conteúdo história do esporte; visualização de obras cinematográficas e; realização de duas resenhas críticas sobre os filmes como avaliação de ensino-aprendizagem. Esta experiência demonstrou seu potencial para a contribuição no processo de ensino-aprendizagem, por permitir que a análise de um fenômeno social de massa indique pistas sobre as contradições existentes na sociedade capitalista. De outro lado, as desigualdades em educação potencializadas pela pandemia de Covid-19 diminuíram o alcance da atividade ao desenvolvê-la em um contexto de ensino remoto.

LA LUCHA LIBRE MEXICANA: UN MEDIO ALTERNATIVO PARA LA ENSEÑANZA DE LA GIMNASIA EN LA EDUCACIÓN PRIMARIA
Authors: Ramírez Salvador Karim Martínez , Inguanzo Ricardo Félix , García Jared Said González
Published: June 2023

Este trabajo académico ofrece una respuesta a la complejidad de la enseñanza y el aprendizaje de la gimnasia (básica y aérea) a través de la clase de Educación Física en la educación básica, específicamente en el nivel primaria, donde las metodologías utilizadas han quedado obsoletas y sobre todo han pasado a convertirse en una barrera para el aprendizaje de los niños, generando pérdida de la motivación y olvidando por completo la práctica significativa que la Educación Física debe tener dentro y fuera de la sesión. Con la intención de generar propuestas en lugar de problemáticas, este colectivo docente se dio a la tarea de buscar innovar por medio de la lucha libre la práctica y la enseñanza de la gimnasia, sin dejar de lado y retomando un tema muy importante y olvidado como lo es la cultura, especialmente la mexicana. Por tal motivo y siendo oportuno que desde la formación docente existe la posibilidad de trabajar con grupos de 3er grado de nivel primaria, se optó por abordar y aplicar este nuevo proceso formativo, haciendo uso de una unidad didáctica que permitió abordar las dimensiones corporales, físicas, cognitivas y simbólicas de cada individuo con el fin de fortalecer y enriquecer la motivación, la participación y el interés por las sesiones de Educación Física y el aprendizaje de la gimnasia en sí.
Carcinoma of the gall bladder
Authors: Vagholkar Ketan
Published: June 2023

Gallbladder carcinoma is fifth most common gastrointestinal malignancy. Main indication for cholecystectomy is gallstone disease. Majority of gallbladder carcinomas are diagnosed during the course of histopathological evaluation of specimens obtained at cholecystectomy. Accomplishing radical cholecystectomy is advisable in these patients. Technically difficult gallbladder dissection during the course of laparoscopic surgery should raise a high suspicion of malignancy. Specimen retrieval bags should be used in all cases to avoid external spillage of bile giving rise to port side metastasis. A good outcome depends on prompt diagnosis and radical surgical resection. It is essential for a general surgeon to be aware of predisposing factors, pathology, patterns of presentation, and surgical options in gallbladder carcinoma.
