Factors Shaping the Reproductive Behavior of Young Families in Russia: Data Triangulation
Authors: Rostovskaya Tamara K. , Vasilieva Ekaterina N. , Kholina Veronika N.
Published: May 2023

The purpose of the study is to identify the factors that influence the reproductive behavior of young Russian families (heterosexual families consisting of two persons below the age of 35 with or without children). The analysis relies on the results of a mass questionnaire survey of young first-time married people (n = 893) conducted in 10 Russian regions in 2019–2020, in-depth interviews with young married people (n = 50) and an expert survey of managers and specialists working for social non-profits (n = 10), both conducted in 2021. Based on the data of the mass survey, we found that there are differences in the values of young families with children and without children. Moreover, young couples may choose to postpone childbearing not only for financial reasons but also because of their marital attitudes and reproductive strategies formed in the process of socialization. Marital behavior has a great influence on reproductive behavior. The differences in the respondents' attitudes to parenthood are determined by their gender roles, experience of having and raising children or absence of such experience. We found that state social support does not have a significant impact on the reproductive behavior of young families in Russia. Expert assessments show that the current measures of social support for young families do not cover all the needs of these families and that there is a perceived need for a more comprehensive assistance model.

Authors: ÇOŞKUN Fatma , YILDIZ Gizem
Published: May 2023

Treatment of PKU (Phenylketonuria) is a lifelong special diet program starting from the newborn period. The aim of this study was to produce an alternative product for PKU patients. Low protein milk substitute, xanthan gum (1%), Nestle nestergel yoghurt gelling agent (1.5%), starch (4%) and pectin (1.6%) were used to produce yoghurt substitue. Control yoghurt was produced from cow's milk. The fermentation of all samples was completed at the end of the 5th hour. The pH of the samples decreased during storage. The total solid matter of the corn starch and pectin added samples were higher than the others. Syneresis values of the samples with xantan gum, pectin and nesterjel were 0% or close to 0%. The shear stress of xantham gum, nestergel, starch added samples were found close to each other. The shear stress of the pectin added sample was higher than for them. L* values of the control and starch added samples, a* and b* values of pectin added sample were higher than those of other samples. The amount of protein and Phe was significantly higher in the pectin added sample than the other samples (p

Published: May 2023

Chiral amines are important building blocks in the pharmaceutical, agrochemical and chemical industries. There is a drive to augment traditional transition metal catalysts with ‘green’ alternatives such as biocatalysts. Transaminase (TA) biocatalysts can be used in combination with ‘smart’ sacrificial amine donors to synthesise a variety of aliphatic and aromatic amines from the corresponding aldehydes and ketones. Despite their enormous potential, the unfavourable reaction equilibrium often limits the widespread application of TAs for industrial synthesis. Recently we disclosed a new biomimetic amine donor N-phenyl putrescine (NPP), which was inspired by the biosynthesis of the dipyrroloquinoline alkaloids. NPP was demonstrated to have good activity with a library of commercial and wild-type TAs (total 25 TAs). This work focused on exploring the use of NPP with the Johnson Matthey TA kit (17 biocatalysts; eight S-selective and nine R-selective) and three different amine acceptors (vanillin, benzaldehyde and acetophenone). NPP worked well with all 17 TAs and gave the corresponding amine products vanillylamine, benzylamine and methylbenzylamine (MBA) in up to 85% high-performance liquid chromatography (HPLC) yield. From the screen, STA-14 was identified as a good biocatalyst for further analysis and used in a comparative screen of NPP versus the commonly used donor iPrNH2. It was found that NPP was the best amine donor and used to prepare S-methylbenzylamine in >99.5% enantiomeric excess (e.e.). This work, combined with our previous study, highlights the potential of NPP in the biocatalytic synthesis of amines.

Published: May 2023

Results of the experimental studies of the effect of reactor wall temperature on the direct oxidation of benzene to phenol in a barrier discharge reactor are presented. The main products of oxidation are phenol, hydroquinone, and pyrocatechol. It has been found out that the content of phenol and pyrocatechol in the mixture remains practically unchanged upon the air or oxygen benzene oxidation. An increase in the reactor wall temperature in the case of air oxidation of benzene results in a decrease in the hydroquinone content in the mixture of reaction products, while in the case of oxygen oxidation of benzene
an increase in the hydroquinone content is observed. An increase in the reactor wall temperature also
promotes an increase in the mass of liquid and solid reaction products, while the elemental composition
of the precipitate remains unchanged.

Published: May 2023

Waste from the metallurgical industry contains many harmful impurities. If improperly handled and stored in open landfills, small particles of this waste can be picked up by the wind, carried over long distances and harm human health and pollute the environment. Lead production waste is especially dangerous. Such objects must be handled well, and various dust protection systems must be used to prevent the spread of dust. It is not a trivial task in the case of large sizes of such objects. The lead waste pile formed by the polymetallic plant near the city of Shymkent, Republic of Kazakhstan, is a huge conical mountain with a base diameter of 240 m and a height of more than a 20-story skyscraper. This pile is not managed at all. The pile produces a large amount of lead waste dust, which is carried by the wind to the city and surrounding areas. A numerical study of the wind flow around a hazardous pile was carried out. The dust generation area for an unprotected pile reaches 6,318.68 m2. This dust generation area affects human health and pollutes the environment near the pile. The barrier dust protection system can significantly reduce the power of harmful dust formation. For the first time, analysis and optimization of a dust protection system consisting of two concentric barriers, where heights are significantly less than the height of the object the system handles, was carried out. The results of the research show that installing this fairly simple system around the lead waste pile reduces the formation of air pollutants by 538 times or 99.81% compared to an unprotected object. In addition, the remaining dust particles that can be picked up by the airflow rise to a height of > 140 m above the Earth's surface when using such a protection system and therefore do not affect human health.

Authors:   The Korea International Trade Research Institute, Zhao Junwei , Park Hyun-Jung
Published: May 2023

Purpose – Helping consumers actively participate and act as co-creators of value is critical to the success of technology-based services. This study focuses on an augmented reality (AR) technology e-commerce scenario to explore the influencing factors and mechanisms related to consumer value co-creation intention. Design/Methodology/Approach – Based on the S-O-R framework and flow theory, we integrated factors to suggest and examine a research model with technical characteristics of augmented reality (interactivity and vividness) as external variables (stimuli), shopper psychological factors (organism) including flow experience, and value co-creation intention (response). A questionnaire survey was conducted on 318 Chinese consumers that had experienced AR shopping, and survey data were analyzed using SPSS and AMOS. Findings – Results show that both interactivity and vividness positively affected telepresence, flow, and mental imagery, which directly and indirectly enhanced consumer value co-creation intention. Research Implications – The results confirm the relationships among technical characteristics, consumer experience factors, and value co-creation intentions in the AR shopping environment. In addition to expanding existing theoretical achievements, this paper also provides practical implications for AR-related industries and shopping platform managers. This study will provide a foundation for future research by increasing the understanding of value co-creation in the augmented reality shopping environment, and provide implications for promoting consumer participation.

Published: May 2023

Purpose – The purpose of this study was to discover strategies for the development of the domestic and international entertainment and tourism industries by analyzing factors that affect satisfaction with entertainment policies in Korea. Design/Methodology/Approach – The Korea Culture and Tourism Research Institute September 7, 2020 - November 2020 SPSS statistical analysis was conducted with 10,088 copies of data collected by the survey up to the 16th. Findings – First, it was analyzed that the importance of entertainment policies had a significant effect on satisfaction with entertainment policies. Second, the entertainment public industry was analyzed to have a significant effect on satisfaction with entertainment policies. Third, it was analyzed that the private entertainment industry had a significant effect on satisfaction with entertainment policies. Fourth, when the private entertainment industry affects entertainment policy satisfaction, it was analyzed that happiness had a significant effect. Research Implications – First, research was conducted in terms of developing K-content international trade. In particular, in a situation where Hallyu entertainment content is being exported (distributed) all over the world, it suggests national countermeasures to protect content so that they can grow in the long term. Second, the importance of entertainment policy, public industry, and private industry identify key variables to increase entertainment policy satisfaction, and when the private industry affects entertainment policy satisfaction, it confirms the moderating effect of happiness to improve related laws and institutions and expand infrastructure. It suggested measures to expand and promote private industrial exports.
The Asymmetric Impacts of Exchange Rate Volatility on Trade Between Korea and Vietnam
Authors:   The Korea International Trade Research Institute, Choi Yoon-Jung , Kim Hong-Youl , Baek Jung-Ho
Published: May 2023

Purpose – In past studies, exchange volatility was assumed to have a symmetric effect on trade, irrespective of exports and imports. In practice, however, the symmetry assumption is not credible. This is because responses to exchange rate uncertainty differ among countries or companies. Thus, this study examines the asymmetric effects of exchange rate volatility on exports and imports as well as in the short- and long terms. Design/Methodology/Approach – To investigate the asymmetric impact of exchange rate volatility on Korea’s trade with Vietnam, the nonlinear autoregressive distributed lag (NARDL) method was applied to export and import data disaggregated by 25 commodities for the period of January 2000 to December 2020. Findings – The results show that the ups and downs of exchange rate volatility have an asymmetric impact on some, though not all, types of Korea's commodities exported to and imported from Vietnam. In addition, asymmetries in exchange rate volatility seem more likely viewed as a short-tern phenomenon rather than a long-term period for Korea’s bilateral trade with Vietnam over the past two decades. Research Implications – Monetary authorities in Korea and Vietnam need to consider the short-run movement in the VND/KRW exchange rate as one of the main factors for determining bilateral trade flows.

Authors:   The Korea International Trade Research Institute, Yim Byung-Jin
Published: May 2023

Purpose – This study is an empirical study on the relationship between climate change and the export and import volumes of the Gyeongnam Region. Design/Methodology/Approach – In this study, we used 26 monthly data from the climate change index, and the export and import volumes of Gyeongnam in Korea from August 31, 2020 to September 30, 2022. We attempt to analyze the mutual influence and causality in the climate change index, the export volume, and the import volume of Gyeongnam in Korea. We wish to analyze the extent of cross-influence. We employ a variance decomposition function based on the VAR model, as well as an impulse response after a cointegration test and unit root test of the climate change index, the export volume, and the import volume of Gyeongnam. Findings – There is at least one cointegration among the first differential data of the climate change index, the export volume, and the import volume of Gyeongnam. Finally, the export volume of Gyeongnam does Granger Cause climate change. Research Implications – This study differs in that it uses the climate change index and climate change. It has limitations in that the study sample is limited and the study period is short.

Purpose – The purpose of this study is to analyze the relationship between large business groups and investment behavior in the IT industry, analyze whether there is a difference in the relationship between the two depending on the level of market evaluation of the firm, and present the implications of the results to the capital market. Design/Methodology/Approach – This study conducts T-Test and OLS regression analysis on 5,214 firm-year data belonging to the Korean IT industry from 2012 to 2020. Findings – The results analyzed in this study are as follows. First, the investment behavior of IT firms differs depending on whether they are a large business group. Those belonging to large business groups are relatively under-invested. Second, there is a difference in the relationship between market value level and investment behavior depending on whether there is a large group of IT firms. Only the non-large group appears to have an over-investment propensity when the market value level is higher. Third, there are differences in investment behavior by market value level (upper/lower) depending on whether or not IT firms are large-scale business groups. Research Implications – The results of this study provide evidence that companies in the IT industry should consider the level of market value when making investment decisions, and are believed to contribute to the respective decision-making of stakeholders and market participants.

Published: May 2023

Purpose – In recent years, with the development of 5G technology and the rise of webcasting, livestream e-commerce has become a main shopping channel for consumers. Capturing the user behavior mechanism and understanding its influencing factors are of great importance for livestream e-commerce. Based on previous studies, this study proposes a research model mediated by herd behavior, attempting to illustrate how the three types of trust in livestream e-commerce affect final purchase intention through herd behavior. Design/Methodology/Approach – To achieve the research purpose, independent variables were selected by searching previous literature on livestream e-commerce, and a questionnaire was designed according to the situation in China. The survey was conducted online, and 312 users were surveyed via questionnaire. SmartPLS3.0 was used to conduct confirmatory factor analysis on variables and test hypotheses through regression analysis. Findings – According to the results of the study, herd behavior has a positive impact on livestream e-commerce consumer purchase intention, and consumer trust in livestream platforms and streamers has a statistically significant impact on herd behavior. Herd mentality plays a mediating role between trust and purchase intention. Research Implications – This study uses the psychological factor of herd behavior to establish an impact mechanism between trust and purchase intention in livestream e-commerce. For livestream platforms and streamers, long-term trust investment in consumers is required to influence consumers in livestream and increase sales opportunities.

Purpose – The purpose of this study is to understand the relationship among Starbucks' ESG management, brand equity, and purchase intention using Starbucks in Shandong Province, China. We also investigate the moderating effects of digital transformation and the mediating effect of brand equity. Design/Methodology/Approach – In this study, a research model was built based on existing studies and demonstrated using multiple regression analysis. Findings – First, except for 'energy efficiency', the remaining independent variables were found to have a significant impact on brand equity. Second, except for 'eco-friendly management', it was confirmed that the rest of all independent variables had a significant effect on purchase intention. Third, the moderating effects of digital transformation and the mediating effect of brand equity were confirmed. Research Implications – Starbucks' strategy of combining “ESG management” and “digital transformation” had a positive significant effect on brand assets and purchase intentions. In addition, although Starbucks is a multinational company, it must comply with Chinese laws in the Chinese market, and this must be noted when dealing with consumers in the Chinese market.

Published: May 2023

Purpose – The purpose of this study is to analyze the relationship between risk managing capabilities, resilience, and shared value creation behavior for local MICE companies. Design/Methodology/Approach – This study will explore what kind of risk managing capabilities local MICE Alliance has used to pass through the long tunnel of Covid 19, and how they have demonstrated their ability to maintain and revive their organizations through risk managing and supply chain capabilities. An empirical survey was conducted with MICE Alliance member companies in regions except for Seoul and the metropolitan area. A total of 190 samples were collected for data analysis. Findings – While the supply chain capabilities had no impact on resilience, business performance resources had an effect on resilience. It is also noticeable that resilience had a significant impact on ESG-based shared value creation. Research Implications – In this study, the relationship between risk management capacity, resilience, and ESG-based shared value creation, which had been conducted in previous studies, was expanded to the local MICE alliance, playing a role in laying the theoretical foundation. In addition, although the supply chain capacity has no effect on resilience, it presents a homework that requires serious consideration for the sustainable MICE industry environment in the future.

Authors:   The Korea International Trade Research Institute, Han Eun-Jin
Published: May 2023

Purpose – The purpose of this study is to identify the predictive factors of medical tourism in Vietnam by analyzing the variables that lead to the annual visitor number. Design/methodology/approach – This study collected data from Vietnamese with experience in domestic and international medical tourism, and focused on Hanoi, Vietnam. In this study, the variable of medical tourism preferences was applied independently. Factors that impacted the number of annual visitors were estimated by the truncated Poisson model. Findings – The results of the TP model analysis of demand for medical tourism are as follows. Among the variables related to socio-economic characteristics, age, marital status, and occupation had a significantly positive effect on the number of annual medical visits. These results imply that it is important to understand socio-economic characteristics to expand demand for medical tourism in Vietnam, which shows high growth potential. The top three variables that gave a significant positive effect on the number of annual medical visitors are the level of medical technology, waiting time, and price, as well as medical service experience. Research implications – The results indicate the need to develop medical tourism products tailored to consumer tastes by subdividing medical technology levels, waiting for time and price, medical experience services, and so on. Thus, the results presented by this study create a starting point for the development of demand forecasting models for the domestic, international, and Vietnamese medical tourism markets in the future.
Buhârî’nin Yazılı Kaynakları Üzerine Bir Araştırma
Authors: Akgün Hüseyin
Published: May 2023

İslam dünyasında hadislerin yazılı kaynakları meselesi öncelikle Fuad Sezgin (öl. 2018), sonrasında ise M. Mustafa el-A‘zamî (öl. 2017) ile öne çıkmış ve bahis mevzu yapılmış bir konudur. Sezgin, Buhârî’nin Kaynakları adlı eseri ile geleneksel rivâyet anlayışımızda devrim niteliğinde bir değişime yol açmıştır. Zira o, daha önce savunulan rivâyetlerin bir asır kadar sadece şifahî olarak nakledildiği iddiasına itiraz etmiş ve Sahîh-i Buhârî örneğinde hicrî III. yüzyılda yazılmış hadis eserlerinin aslında kendinden önceki yazılı kaynaklara dayanılarak telif edildiklerini savunmuştur. Ancak Sezgin bu iddiasını öyle bir noktaya getirmiştir ki, İmam Buhârî’nin el-Câmiu’s-sahîh’inin tamamının kendinden önceki yazılı kaynaklara dayandığını söylemiştir. Bu iddianın ne kadar gerçeği yansıttığı bizde bir merak konusu olmuştur. Gerçekten söz konusu dönemde hadislerin şifahî rivâyeti tamamen ortadan kalkmış ve Buhârî eserini sadece yazılı kaynaklara dayandırarak mı ortaya koymuştu? Ayrıca Buhârî’nin yazılı kaynakları kullanımı ne düzeydeydi? Elinizdeki makalede bu sorulara cevap bulmaya çalışacağız.
Occurrence of the potato leaf miner, Liriomyza huidobrensis (Diptera: Agromyzidae), and parasitoids in potato fields and natural vegetation of the Western Cape province, South Africa
Authors: Mugala Thabu , Visser Diedrich , Malan Antoinette Paula , Addison Pia
Published: May 2023

The leaf miner, Liriomyza huidobrensis (Diptera: Agromyzidae) is a polyphagous fly, which infests a wide range of vegetables and ornamental plants. However, scant knowledge exists of the biology and ecology of the pest in the Western Cape province of South Africa, both of which are essential components in developing an effective management programme. Several aspects of its biology and ecology were studied in two potato [Solanum tuberosum L. (Solanales: Solanaceae)] fields in the Sandveld region during both winter and summer months. The population densities of adult L. huidobrensis were monitored using yellow sticky traps, which were retrieved and counted once every two weeks (June 2019 to January 2020). The number of leaf miner adults caught throughout the summer and winter monitoring periods was significantly different. In addition, 50 randomly selected plants were assessed for leaf damage (in the form of punctures and mines) using presence/absence sampling. Leaf miner persistence within the soil was confirmed through one-time soil sampling of the two fields, one month after harvesting. Leaf miner pupae were detected in the soil samples after the potatoes were harvested. However, no adult emergence was recorded among the collected pupae under laboratory conditions. The observed trend was that the traps, in both fields, caught an increasing number of leaf miners as the crops matured. Damage occurred in both the monitored fields as early as week four, after plant emergence. Of the five parasitoid species collected, Diglyphus isaea (Hymenoptera: Eulophidae) was the most abundant.
Love at first bite? Pre-release surveys reveal a novel association between a native weevil and the invasive Nymphaea mexicana Zuccarini (Nymphaeaceae) in South Africa
Authors: Reid Megan , Hill Martin , Coetzee Julie
Published: May 2023

Classical biological control aims to suppress alien invasive plant populations by introducing host-specific natural enemies from the native range. This relies on the assumption that invasive plant populations in the invaded range benefit from the release of natural enemies. Pre-release surveys in the invaded range are a useful way to determine if enemy release applies to a particular invasive alien plant, and to determine what other factors may contribute to the invasion. Similarly, pre-release surveys gather information that can be used to compare invaded sites before and after the release of biological control agents and may also identify whether natural enemies have been accidentally introduced into the country. Pre-release surveys were conducted in South Africa on the invasive Nymphaea mexicana Zuccarini (Nymphaeaceae) to gather such information about this species, for which a biological control programme is being developed. There was lower diversity and abundance of herbivores in the native range compared to South Africa, suggesting that N. mexicana does experience enemy release at most sites in South Africa. This support for the enemy release hypothesis justifies the investment in biological control for its management. However, a native weevil, Bagous longulus Gyllenhal (Coleoptera: Curculionidae), was found feeding and reproducing on N. mexicana at three sites, resulting in damage to the leaves and suggesting that a novel association has formed between these species. Bagous longulus may have potential to be distributed to sites of N. mexicana where it is not present, though further investigation is necessary to confirm if its host range is suitable for this to be a safe endeavour. With the exception of sites where B. longulus was present, leaf sizes were large and damage was low, and there is no evidence that any natural enemies have been accidentally introduced from the native range. Findings such as these emphasise the importance of conducting thorough surveys during the development of biological control programmes.

Authors: Sonia Ali , Sakshi Joshi , Jyoti Agarwal
Published: May 2023

With the advancement in the field of agriculture and industrial regime, numerous metals such as lead, cadmium, mercury, zinc, copper, arsenic, etc. are released into the environment as effluent. These metal ions enter water bodies and generate many health issues. Considering their harmful impact on human lives, numerous fluorescent probes have been developed in recent years to detect the presence of these metal ions. The fluorescent probes are used owing to their ease of operation, good selectivity, and high sensitivity. The interaction between functional groups present in the structural framework of the probe and the empty orbitals of metal ions is responsible for the chemo selectivity of the probe. This report summarizes the organic probes which possess benzofuran and naphthofuran moieties and act as fluorescent chemosensors toward metal ions. The selectivity and sensitivity of these chemosensors along with the limit of detection have also been discussed.

Authors: TEMEL Süleyman , KESKİN Bilal , GÜNER Zeynep , ATALAY Ali İhsan
Published: May 2023

Common Reed (Phragmites australis (Cav.) Trin. Ex Steud, which is remained inactive and grown in saline

drainage channels, has been seen as an important potential to reduce the roughage deficit needed in animal nutrition. For this purpose, some yield, fermantation, chemical and nutritional characteristics of P.australis herbage and silage obtained from the end of the vegetative stage (EVS), the beginning of panicle (BP) and the full panicle stage (FPS) were determined. The study was carried out in 2021-2022 in Igdir, which is located in the North-East of Turkey. The results showed that the forage yield characteristics increased as the development period progressed and also that high lactic acid, low pH, acetic, propionic and butyric acid contents desired in silo feeds were obtained from the cuttings at FPS. In addition, ammonia production was low in silages at BP and FPS, but high the fleig score. It was observed that the dry matter digestibility, metabolic energy and relative feed value were higher while dry matter and crude protein ratio, acid detergent fibre and crude ash content of herbage according to silage were lower. On the other hand, the desired chemical and nutritional values in both herbage and silage were determined during the most suitable BP. As a result, it was determined that the common reed was appropriate to harvest in FPS for a silo feed with high yield and fermentation properties. In addition, it was concluded that the herbage and silage harvested at BP produced a higher quality feed material in terms of nutritional and chemical composition, respectively.
Fridays for Future and Mondays for Memes: How Climate Crisis Memes Mobilize Social Media Users
Authors: Johann Michael , Höhnle Lukas , Dombrowski Jana
Published: May 2023

Modern protest movements rely on digital activism on social media, which serves as a conduit for mobilization. In the social media landscape, internet memes have emerged as a popular practice of expressing political protest. Although it is known that social media facilitates mobilization, researchers have neglected how distinct types of content affect mobilization. Moreover, research regarding users’ perspectives on mobilization through memes is lacking. To close these research gaps, this study investigates memes in the context of climate protest mobilization. Based on the four-step model of mobilization, a survey of users who create and share memes related to the Fridays for Future movement on social media (N = 325) revealed that the prosumption of climate crisis memes increases users’ issue involvement and strengthens their online networks. These factors serve as crucial mediators in the relationship between users’ prosumption of climate crisis memes and political participation. The results suggest that mobilization through memes is effective at raising awareness of political issues and strengthening online discussion networks, which means that it has strategic potential for protest movements. By looking at memes from the perspective of their creators and examining a specific type of social media content, this study contributes to the literature on digital mobilization.

Use of combined hormonal contraceptives in women with uterine fibroids: opinions of practitioners
Authors: Aganezova Natalia V. , Aganezov Sergey S. , Shilo Maria M.
Published: May 2023

BACKGROUND:Uterine fibroids are increasingly diagnosed in patients of reproductive age. Combined hormonal contraceptives provide reliable protection against unwanted pregnancy and help to reduce or eliminate various clinical manifestations of uterine fibroids. In practice, obstetrician-gynecologists have barriers to prescribing combined hormonal contraceptives to patients with uterine fibroids.
AIM:The aim of this work was to study the features of the clinical approach of obstetrician-gynecologists to the management of patients with uterine fibroids interested in combined hormonal contraception.
MATERIALS AND METHODS:The method of voluntary anonymous questioning was applied to 366 obstetrician-gynecologists. The work experience of 62.1% (n= 227) of doctors was 10 years or more. The questionnaire included questions about various aspects of the use of combined hormonal contraceptives for contraception in women with uterine fibroids.
RESULTS:Only every second (47.5%;n= 174) obstetrician-gynecologist correctly assigns uterine fibroids to the first category of acceptability for combined hormonal contraceptives. The presence of an asymptomatic submucous myomatous node (FIGO 12) or dysmenorrhea in women with uterine fibroids is considered by 29.0% (n= 106) and 5.7% (n= 21) of obstetrician-gynecologists, respectively, as a contraindication to the use of combined hormonal contraceptives. Every ninth participant (11.4%;n= 42) believes that the presence of uterine fibroids limits the duration of use of combined hormonal contraceptives for contraception to 15 years. Almost half (45.6%;n= 167) of the respondents believe that combined hormonal contraceptives have various effects on uterine fibroids (cause regression or growth of fibroids, increase the risk of new fibroids). More than half (53.3%;n= 195) of the respondents are not informed about the reduction in the risk of developing uterine fibroids when using combined hormonal contraceptives for five years or more.
CONCLUSIONS:In the analyzed cohort of experienced obstetrician-gynecologists, we identified their barriers to prescribing combined hormonal contraceptives for contraception for women with uterine fibroids. Those are incomplete awareness of the acceptance criteria for combined hormonal contraceptives and insufficient awareness of the lack of effect of combined hormonal contraceptives on the size of existing myomatous nodes and a decrease in the risk of developing uterine fibroids when using combined hormonal contraceptives for five or more years.
Group Audits and Investment Efficiency
Authors:   , Chen Li-Jen , Choy Hiu Lam
Published: May 2023

This study examines whether group audits can impact the investment efficiency of multinational companies (MNCs). I argue that group audits have a negative impact on investment efficiency because they can cause an opaque information environment and impair auditors' monitoring efficacy for the MNCs. Since inefficient investment takes forms of underinvestment and overinvestment, I hypothesize and find a conditional positive association between group audits and underinvestment (overinvestment) for MNCs in settings prone to underinvest (overinvest). That is, among MNCs that are likely to underinvest (overinvest), MNCs with group audits underinvest (overinvest) more. Furthermore, to reduce the concern that using group audits is a function of MNCs' characteristics, propensity score matching (PSM) and entropy balancing procedures are employed to pre-treat the sample. The results were held by using the treated samples. Several cross-sectional and additional robustness analyses are conducted and confirm that the results are not random.

Abstract: This article aims to explore the contributing factors of tolerance in senior high school students. This research covers the concept of tolerance theory and aspects that contribute to tolerance. The study was carried out using a cross-sectional survey method with a quantitative approach. The population in this study were high school students in the city of Bandung, Indonesia. The research sample was taken using a random sampling technique. The research sample consisted of 300 high school, vocational high school, and Madrasah Aliyah students in the city of Bandung. Data collection was completed using tolerance instruments, and data analysis used confirmatory factor analysis (CFA). The results of this study indicate that the greatest contributing aspect to the tolerance of senior high school students in Bandung was the aspect of peace. Meanwhile, the lowest contribution was observed in the aspect of equality. The peace aspect consists of indicators of caring, fearlessness, and love. The results of this study can be used as material and consideration for further research to develop a model or program of guidance and counseling services empirically designed to develop tolerance.

Abstract: This study develops a career pocketbook as a career information media to accelerate career understanding among primary school students. This research and development study was completed in a number of stages, including (1) preliminary study, (2) product design, (3) product development following the design, (4) limited tryout, and (5) product revision. For the limited tryout, we conducted a number of tryouts. In the first limited tryout, we involved the experts (from the guidance and counseling field, career guidance and counseling field, and Indonesian language), followed by an individual tryout involving nine students and three counselors, then a small group tryout with 15 students. The primary data were collected using a questionnaire. Further, the data from the experts were analyzed using content analysis, and the experimental data were analyzed using the Wilcoxon test. The results of the analysis of the tryout data suggested that the developed career pocketbook is feasible to be used as a guidance and counseling media, primarily to enhance elementary school students’ career comprehension. Further, this career pocketbook can be suggested as the media for students’ career guidance and counseling.

A család természete a közgazdaság-tudományban : A neoklasszikus megközelítésektől az intézményi felfogásig
Authors: Golovics József
Published: May 2023

Jelen tanulmány a család közgazdaságtanáról ad áttekintést, bemutatva, hogy a különböző közgazdaság-tudományi megközelítések miként tekintenek a családra, s miben látják annak funkcióját. Először a háztartások feketedoboz-modelljét vázoljuk fel, amely egy egyszemélyi döntéshozóként működő fogyasztási egységként tekint a családra. Ezután a családot kollektív döntéshozóként kezelő neoklasszikus irányzatra térünk rá, amelyben már a háztartáson belüli optimális erőforrás-allokáció kérdése kerül a középpontba. Végül, de nem utolsósorban a családra szerződésként, a tranzakciók irányítási struktúrájaként tekintő intézményi közgazdaságtani megközelítés alapvetéseit ismertetjük. Az áttekintés során kitérünk az egyes modellek hiányosságaira, továbbá arra is, hogy az újabb megközelítések miben lépnek túl a megelőzőkön s mivel egészítik ki azokat.
Emotion concept disgust and its German counterparts: Equivalence determination based on language corpora data

Published: May 2023

Our two-stage methodology was tested in order to determine the most accurate equivalent for Anglo-Saxon emotion concept (EC) disgust among German ekel, abneigung, abneigung and abscheu. At the first stage, the authors identified the closest in terms of content equivalents to disgust on the basis of the comparison of the German ECs names definitions in explanatory and bilingual dictionaries. It was established that equivalence with disgust, albeit incomplete, is shown only by the nouns Ekel and Abscheu, which are so semantically close to each other that they can be used interchangeably in some contexts. At the second stage, on the basis of a comparative analysis of the most frequent collocates of the concept names disgust, ekel and abscheu in representative corpora of the English and German languages, (a) the relevant content of these concepts was established and (b) a comparison of their semantic structures was made according to the criteria of arousal and valence. A comparison of the semantic structures of disgust, ekel and abscheu revealed that both German concepts show numerous overlaps with disgust. At the same time, abscheu is semantically more similar to disgust than ekel. This indicates that the transfer of disgust to the German language community by means of ekel and abscheu can be quite adequate, since both of these concepts evoke associations in representatives of German-speaking culture similar to those that arise in Anglo-Saxons in connection with disgust.
Simultaneous estimation of reference temperature and heat transfer coefficient in transient film cooling problems

This paper aims to simultaneously estimate the reference temperature and heat transfer coefficient in film cooling situations from transient temperature measurements. The exist-ing steady-state technique is a tedious process and employs distinct boundary conditions to evaluate each parameters of the film cooling. Applying different boundary conditions may lead to errors in the estimated parameters due to differences in aerodynamic condi-tions. On the other hand, a transient technique can estimate both parameters in a single test by utilizing short-duration transient temperature data. Hence, the present study uses a novel approach for solving transient film cooling problems based on the inverse heat con-duction approach, which can simultaneously estimate heat transfer coefficient and refer-ence temperature. The present method employs an optimization technique known as the Levenberg-Marquardt Algorithm. The objective function for the inverse algorithm is con-structed using the analytical solution of a transient one-dimensional semi-infinite body. The transient surface temperature data required for the present analysis is obtained through a numerical simulation of film cooling arrangement over a flat surface. Laterally averaged effectiveness and heat transfer coefficient for blowing ratios of 0.5, 0.8, and 1.0 are analyzed using the present technique and compared against the steady-state simulation results to demonstrate the methodology. An average deviation of around 7% for the estimated effec-tiveness and 4% for the heat transfer coefficient values are observed between the present IHCP method and the steady state simulation results. The deviation in heat transfer coeffi-cient predominately occurred near the film hole exit of x/d < 5, which might have occurred due to the conjugate solution employed in the present work.
