Authors: Utami Khalida , Amyulianthy Rafrini , Astuti Tri
Published: February 2023

Integrated reporting has been proposed as a solution to the problem of misleading information in company reports, but its implementation has not been fully realized because regulations in each country regarding the implementation of corporate reporting in the form of IR are both mandatory and voluntary. The research proposes to assess Indonesia's readiness to apply IR among State-Owned Enterprises (SOE), and whether IR can be used as mandatory or voluntary disclosure. This study employs a quantitative approach that begins with data analysis on state-owned enterprises that issued annual reports on the Indonesia Stock Exchange. At a later stage, the overall score is calculated and evaluated with sensitivity analysis. The study finds the higher the amount of disclosure of firms implementing IR in Indonesia, the lesser the information gap obtained which can lead to a more effective corporate governance system This research has implications for companies in considering the application of integrated reporting in making decisions related to investments both in the short and long term, so that they can support the company's sustainable development strategy.

Published: February 2023

This study aims to test the effect of earnings autocorrelation and earnings volatility on audit delay. In the process of the test, researchers used multiple regression analysis using a research sample of 105 manufacturing companies or 525 observations with the observation range of 2015 – 2019. The result, it showed that earnings autocorrelation had an effect on increasing audit delay. It is similar that the earnings correlation which also affects audit delays. The results of this study provide implications that auditors must be more careful in carrying out the audit process, especially in capturing earnings information from time to time. This is because earnings are the information that is often used by the users in assessing a company and used to manipulate earnings. For future research, it is suggested to use specialist industrial auditors as a coding variable in an effort to suppress the occurrence of long audit delays

Published: February 2023

This study aims to explore the controls implemented in Village Owned Enterprises (BUMDes) financial management from the perspective of the three lines of defense at BUMDes "KITA" Wologai Tengah Village, Ende, East Nusa Tenggara. This study uses a qualitative descriptive method with sample collection techniques using primary data through FGDs and in-depth interviews with BUMDes management and village government, as well as secondary data through supporting documents. The research data obtained is processed by coding the results of the data collection stages, reduction, verification, and formulation of answers to research problems. The result shows that Three Lines of Defense model adopted by BUMDes “KITA” has not provide an optimal result in every line. This is because of this BUMDes is still new which has been running about three years so they are still focusing on the how to develop the BUMDes. So, they have not considered business continuity too much through risk mapping and control in financial management.  This research has implications for the need for further consideration in using the concept of the three lines of defense for BUMDes, in addition to the need for the role of the central government in optimizing risk management to mitigation of fraud.
Kualitas Pelaporan Keuangan : Peran Keahlian Industri Pada Komite Audit
Authors: Amalia Ashifa
Published: February 2023

This study aims to look at the role of audit committee’s industry expertise on the quality of corporate financial reporting. By using the purposive sampling method for all companies listed on the Indonesia Stock Exchange (IDX) in the period 2016 to 2019, the final sample size was 584 observations. The data needed is obtained from the company's financial reports, the Osiris database, the company's website, the Bloomberg website, and LinkedIn. By testing descriptive statistics and multiple linear regression using STATA 14.0 software, this study shows that when a company's audit committee has only one of industry and accounting or financial expertise, the supervisory role of financial reporting tends to be less effective. On the other hand, when the company's audit committee team has both expertise, the supervisory role of the audit committee increases so that the quality of the company's financial reporting also increases. These results imply that the audit committee's industry expertise is useful for increasing the effectiveness of financial reporting supervision so that this expertise needs to be considered as a factor in selecting an audit committee.

Published: February 2023

This study assumes that when a baby has its demands met by the environment in which it is inserted, a well-established bond with its mother and/or caregivers can start its process of finding itself, seeking to develop its autonomy and independence.
The present study aims to investigate the affective bond between mother and baby when the child remains full-time in a daycare. Studying the bonds between mothers and babies, in this context, is relevant to think about strategies and actions for health promotion. Regarding the methodology, it is a qualitative and exploratory field research. Five mothers with children up to 1 year and 3 months old participated in this study, who during the day remain in full-time municipal and private schools, in a municipality in the northwest of Rio Grande do Sul. For data collection, a semi-structured interview was carried out and the necessary ethical principles were met. With this study, it was observed that the mothers interviewed, each in their own way, seek to interact with their children in different ways when they are not at school. It has been also found that mothers with a support network are able to dedicate more of their time to their babies, while mothers who have the network for less time are able to dedicate themselves less due to household chores, but both are dedicate. It was understood that it is possible to develop a good bond, even not being together all day.

Published: February 2023

Stein-Leventhal syndrome, currently known as polycystic ovary syndrome (PCOS), is a common ovulatory disorder among women, affecting approximately 6-19% of the female population who are in menopause. It is characterized by presenting hyperandrogenic, reproductive and metabolic alterations. Although its etiology is complex, the relationship between genetic predisposition and environmental factors in the pathology has been proven. Furthermore, the pathophysiologic mechanisms that lead to PCOS are multifactorial, and it is believed to be a complex multigenic disorder, including hypothalamic-pituitary axis abnormalities, steroidogenesis, and insulin resistance. Treatment for PCOS aims to reduce the manifestations of hyperandrogenism, regularize menstrual cycles and correct metabolic changes. This is a systematic literature review, in which a survey of 47 articles was carried out, of which 16 articles were used. Inclusion criteria were articles dealing with polycystic ovary syndrome, in Portuguese and English. At the beginning of the research, 47 articles were selected that fit the keywords, of which 31 (65.9%) were excluded, which did not address the polycystic ovary syndrome. This paper reports the definition of PCOS, its causes, pathophysiological mechanisms and diagnostic criteria. In addition, this article on the treatment of PCOS exposes that the practice of physical exercise, together with nutritional guidance, are important for the improvement of the symptoms of the syndrome. FINAL: The importance of early diagnosis and treatment is emphasized, in order to prevent metabolic, hyperandrogenic and reproductive changes that affect the quality of life of patients with PCOS.
Design and Optimization of a Polyethylene Oxide-Based Matrix Tablet of Metoprolol Succinate Using Design Expert Software
Authors: Dighe Pearl , Deshpande Mangirish
Published: February 2023

Hypertension is a common lifestyle disorder, the prevalence of which advances with age. In the case of antihypertensive therapy, patient compliance is hampered, especially in geriatric patients, if the dose is b.i.d or more, as it is difficult for the patient to remember and take medicine at a scheduled time. The present study involves the fabrication of a sustained-release matrixdesigned tablet using a combination of polyethylene oxide (PEO) polymers and metoprolol succinate as the model drug. The tablet is optimized and evaluated for its in-vitro release using the Design expert software. Polyethylene oxide is a non-ionic hydrophilic polymer which is directly compressible. Polyox WSR 301 and 303 grades have been used in the study to get the desired sustained release of 12 h. The formulations were analysed for various pre-compression and post-compression characteristics. The polymers Polyox WSR 301 and 303 influence drug release are measured using a 32 factorial design where the concentration of drug released at various time points has been analysed statistically as a response. Response surface plots demonstrate and depict the effect of the variables, thus aiding in optimization. All the formulated batches exhibited acceptable pre and post-compression characteristics. The optimized formulation M05 showed a sustained drug release up to a 12 h period. Thus polyethylene oxide can be used as an excellent sustained-release matrix polymer due to its ability to gel and prolong drug release from a matrix. Due to their molecular weight, a combination of two grades of polyethylene oxide helps reinforce the drug release.

Movement and Suspension：A Stylistic Study of Rībi Hideo’s Novels
Authors: FUJIWARA Dan
Published: February 2023

Since the early 1990s literary works that critics would later call “border-crossing literature” (ekkyō bungaku) have emerged on the Japanese literary scene. These works, which are primarily characterized by being written in Japanese by non-native authors, have to-date tended to challenge the concept of “Japanese literature”. A number of studies have explored this very issue in taking into account some similarity with literary genres such as the “Japanese literature of Korean residents in Japan” (Zainichi chōsenjin bungaku). It should be noted, however, that today’s border-crossing writers use Japanese language for personal—or even esthetic—reason unlike postcolonial writers who could not have any other option than writing in their colonizer’s language. In that respect, what seems necessary today is also an analysis that takes a closer look at how today’s border-crossing writers write in Japanese language, namely their writing style. This paper adopts this approach in dealing with Rībi Hideo’s novels, with a particular focus on the fact that most of them feature the theme of a form of travel which is not characterized by the idea of free-flowing movement. By analyzing some relevant examples, I show how this American author develops his original writing style, which is central to his narratives.
Japanized Modern Dance “Bikkono Odori”(Crippled Dance) in Kawabata Yasunari’s Waltz of Flowers(1936)
Authors: KUMAZAWA Masaho
Published: February 2023

Kawabata Yasunari’s Waltz of Flowers (1936) is a novel that was originally a screenplay for a movie in which several popular female dancers were going to perform. Although the plan to make this film was abandoned, the screenplay of Waltz of Flowers is a good example of modernist work in the early Showa period, and the subsequent novel displays the crossover characteristics that result from combining film and dance with narrative fiction.
However, in previous research on Kawabata’s work little attention has been paid to Waltz of Flowers. Instead, much critical work has been done on Snow Country (1935), which was serialized at the same time, so it must be said that there is a bias in the history of this research. To redress this deficit, this paper firstly presents the critical literature on dance in the 1930s, and emphasizes the cultural context of modern dance, as a basis for reading Waltz of Flowers. In particular, it focuses on the three dance scenes in the novel：Suzuko and Hoshie’s duet at the beginning, Hoshie’s solo dance in the middle, and “Bikkono Odori” (crippled dance) near the end. The paper argues that “Bikkono Odori” was a form of Japanized modern dance which connected the styles of Japanese modern dancers in the 1930s.
The Past and Future of Taiwanese Art：A Look Back over the Past 100 Years
Authors: SUZUKI Eka
Published: February 2023

From the Japanese colonial period to the present, the question, “What is Taiwanese art?” has been asked over and over again, and a clear answer has yet to be found. This is not only a search for identity but is also rooted in the pain of Taiwan’s history, as artists address the shifting national borders and the nation state of Taiwan. In the past few years, several important exhibitions of Taiwanese art have been held. The study of Taiwanese art history, which had been a rather minor academic field, has gradually gained momentum. Today, many art historians are attempting to depict Taiwan from the perspective of the island and the many ethnic groups and foreigners who reside there. Furthermore, since many Taiwanese artists and scholars have studied and researched in Japan for over a century now, the study of Taiwanese art history will hopefully develop more actively not only in Taiwan but also in Japan.
Natsuki Ikezawa and the Southward Imagination：Postwar Japan and Writers Wandering Abroad
Authors: NAKANE Takayuki
Published: February 2023

This paper focuses on Natsuki Ikezawa, who continues to question the meaning of people traveling, and aims to examine his view of the South Seas. Natsuki Ikezawa (1945-) is a famous writer who has lived in various places both in Japan and abroad, and traveled to various places around the world, living in Greece for 3 years, Okinawa for 10 years, and France for 5 years. An important place for Natsuki Ikezawa’s creative activities is the South Seas. It was a trip to Micronesia at the age of 27 that marked the beginning of his journey. Since then, he has visited Micronesia many times. Natsuki Ikezawa’s travels and his impressions of the South Seas can be learned in detail from essays and reviews such as “Kaizu to Kokainisshi (Nautical Chart and Logbook)” and “Ikezawa Natsuki no Tabinikki (Ikezawa Natsuki’s Travel Map)”. This paper surveys the cultural history of modern travel/tourism and examines the changes in the use of words related to travel. Next, after the Liberalization of Overseas Voyage in 1964, the literary works of Sou Aono and Wahei Tatematsu, who have experience wandering abroad, writers of the same generation as Natsuki Ikezawa, are compared and verified. Finally, the author considers Natsuki Ikezawa’s views on travel and the South Seas, mainly focusing on his essays and criticisms on the South Seas.
The Present of Nanyo Fantasy as a Healing Space：Desire for Purity in Banana Yoshimoto’s Niji
Authors: LEE Sanghyuk
Published: February 2023

The Yoshimoto banana of  depicts “Nanyo” = Tihiti as a medium for healing and recovery. The space could be this medium because it was a place overflowing with purity and primacy. However, due to this desire for purity and primacy, the possibility of otherness = hybridity = uncanniness is castrated in the space. Therefore, the danger of a kind of modern violence is included in  which talks about pure and beautiful healing and recovery. In addition, Yoshimoto Banana talks about connection with the world based on the assumption of “family” as the basis for restoring “pure me” and “primary me.” However, by setting the unit of “family,” the possibility of “me=subject” who continues to worry about himself, such as Kenzaburo Oe, is eliminated.
Of course, this very point may be the possibility of “new literature,” and the background of the times in which individuals in the 2000s who cannot be the subject are being expressed. However, in reverse, it can also be read as a text that shows the danger that an individual in the impossibility of subjectivity in the 2000s can desire purity and unity and exclude and loathe “others.”

Published: February 2023

Graphene-based preparations are the most promising materials in biomedicine. This review is aimed at analyzing data on the interaction of graphene oxide nanoparticles with different types of cells of the immune system: neutrophils, monocytes, macrophages, dendritic cells, T- and B-lymphocytes, NK and iNKT cells. Scopus publications from 2011 to May 2020 were analyzed. The primary vector of the graphene oxide nanoparticles' effects is associated with cell activation and the formation of a proinflamma-tory profile of the immune response. At the same time, the functionalization of the graphene oxide surface with the biocompatible polymers leads to a decrease in its cytotoxicity, and in some cases, to suppression of cell activation. The interaction of graphene oxide nanoparticles with cells depends on numerous factors, such as direct and lateral sizes, oxidation state, functionalization, number of layers, 3D configuration, as well as the microbiological purity and pyrogenicity of graphene. Together, these characteristics determine whether graphene oxide nanoparticles must stimulate or suppress the immune system. These multidirectional possibilities of graphene oxide can be useful in the development of adjuvants, new drug delivery mechanisms, and modern biosensors.

Authors:   Pacific National University, Kravchuk V. A. , Kravchuk E. V. ,   Far Eastern State Transport University
Published: February 2023

A method for prestressing thin-walled beams with an asymmetric cross section is described. The parameters of the stressed and strained state of the rods are established. By comparing the kinetic and potential energies of composite rods, the circular frequency and angular velocity of conventional and pre-stressed beams when loaded with a single load are determined using the energy method. Stressed and deformed state of ordinary and pre-stressed steel beams under sudden single rotation of the section of the support node has been investigated. It has been established that pre-stressing does not affect the stressed and strained state of the support nodes. The maximum influence of the pre-stressing is set in the area of the maximum moment from the external load. The bearing capacity of the beams changes insignificantly with a sudden single rotation of the support nodes.

Methodology for the design and construction of non-rigid road pavement with varying strength values across the width of the roadway
Authors:   Belarusian National Technical University, Zhukouski Ya. M.
Published: February 2023

The article is devoted to topical issues of designing non-rigid road pavement. At present, the issue of road pavement design is not paid due attention, taking into account the real impact of traffic loads, moisture accumulation and freezing. Traditionally, road pavement is constructed with the same strength for the entire width of the carriageway of a multi-lane highway, with the same design for both the busiest lane and secondary lanes. Moisture accumulation and freezing are not taken into account in strength calculations. The proposed methodology allows combining these factors. The results of the study of this article can be used in the design of non-rigid road pavements.

Recommendations on the orientation of layers for smooth surface panels are given.
Influence of ambient temperature on the frequencies of free vibrations of thin-walled main gas pipelines of large diameter at above-ground laying
Authors:   Industrial University of Tyumen, Razov I. O.
Published: February 2023

The influence of the ambient temperature on the dynamic characteristics of the above-ground main pipeline of large diameter is investigated. On the basis of the calculation scheme in the form of a thin-walled cylindrical shell and a geometrically nonlinear version of the semi-momentless theory of cylindrical shells, the frequencies of free vibrations are determined. The design scheme takes into account the joint influence of the internal working pressure, the parameter of the longitudinal compressive force, and the temperature. On the basis of the equation of motion in forces, taking into account the assumptions of the semi-momentum theory and external influences, the equation of motion in displacements is obtained. Boundary conditions are assumed to be hinged, pipes of medium length and long ones are considered in the range of length-to-radius ratio 8<L/R<15 from support to support. A study was made of the influence of temperature changes on the frequencies of free vibrations of above-ground gas pipelines for various values of the parameter of the longitudinal compressive force and geometric characteristics. The dependence of the change in the frequencies of free vibrations on the heating and cooling of the pipeline section is established, taking into account the combined effect of the internal working pressure and the parameter of the longitudinal compressive force.

The preservation of the historical appearance of St. Petersburg is one of the urgent issues in the field of architecture and urban planning of Russia. Despite of numerous publications on this issue, organizations operating cultural heritage sites face poor quality or lack of project documentation, which hinders the reconstruction process. The article proposes a solution to these problems, namely, the development and continuous updating of operational information models of buildings, or digital twins. The purpose of this study is to identify the features of interaction between specialists from various sections of project documentation when creating digital twins of historical buildings and structures. As a result of the study, the authors propose a methodology for interaction of specialists performing the construction of operation model in the information modeling environment. A step-by-step method of interaction of specialists is offered.

Published: February 2023

The article presents a substantiation of the method designed to analyze the relationship between risks and failure to keep deadlines in construction project installation work and assess its impact on the duration of a construction project. Delays and risks leading to the untimely project completion are one of the most frequent and major problems in construction projects. Available research works on qualitative and quantitative risk assessment do not take into account the fact that the value of the risk criteria depends on many factors, for example, the temporal and spatial location of the task to which the risk is assigned. Neither do they take into account the dependence and interaction between risks. Our study additionally proposes to break down the project schedule into weekly checkpoints, where we apply the weekly work progress index, the average weighted index of each risk for critical and non-critical work, to determine the proportion of each risk in order to provide the necessary information to decision makers to develop appropriate response measures. Based on the example calculation we give in the article, it has been determined what risks have the greatest impact on compliance with project work deadlines.

The paper examines the assumptions underlying a whole group of methods for estimating the parameters of shock waves (pressure waves) during the combustion of spherical fuel-air clouds - the so-called parametric formulas. The formulas allow to determine the parameters of pressure waves from the given energy release and combustion rate. To do this, a complete system of gas-dynamic equations is solved using high-precision numerical simulation. In this case, the combustion front is explicitly distinguished in the form of an infinitely thin discontinuity, on which the laws of conservation of mass, momentum, and energy are satisfied. The results of such a numerical calculation are compared with calculations using the corresponding parametric formulas. Clouds of a stoichiometric mixture hydrogen-air are considered. It is shown that the parametric formulas describe the expansion of clouds of hot products with a good degree of accuracy. Here, there is complete agreement with the direct numerical simulation. It is also shown that the parameters of pressure waves are satisfactorily described both in the calculation by parametric formulas and in direct numerical simulation. In this case, within the cloud, there is a greater increase in pressure than the parametric formulas predict. This is explained by the fact that the assumptions used in the formulas regarding the behavior of the flame front as an impenetrable piston do not fully reflect the physical processes: the combustion front is a semipermeable piston, and some of the mass of the initial mixture still penetrates through it. The third factor considered, which determines the achieved pressures, is the rarefaction wave that occurs in the air after the cloud burns out. This wave propagates in combination with the leading pressure front formed during combustion initiation. The extent of this complex remains practically constant, and its attenuation during spherical propagation is adequately described by the parametric formulas.
