This study was designed to assess the frequency of co-existence of H. Pylori in gastric and gallbladder mucosa of patients with acute cholecystitis or who had symptoms of cholelithiasis. This cross-sectional analysis was conducted at Bahria Town International Hospital Lahore from September 2020 to September 2021. The study consisted of 51 participants, all diagnosed with either acute cholecystitis or symptomatic cholelithiasis. Information regarding the patients' ages, genders, and the H. pylori existence in the mucosa of their gastric and gallbladders was collected and analyzed with SPSS version 22. H. pylori was discovered in the gallbladder mucosa of 22 individuals, which accounts for 43.1% of all cases, and in the gastric mucosa of 16 patients, which accounts for 31.1% of all cases. The co-existence of H. pylori in both the mucosa of the gallbladder and gastric wall was found in six (11.8%) patients. The co-existence of H pylori was significantly greater in patients with acute cholecystitis compared to those with cholelithiasis (p = 0.021). This study showed no significant relationship between age and smoking history with the co-existence of H. pylori in gastric and gallbladder mucosa. The findings of this study indicate that the presence of H. pylori infection is extensive in the gallbladder and stomach mucosa of the patients diagnosed with acute cholecystitis and cholelithiasis. When evaluating patients with gallbladder issues, it should be considered the presence of H. pylori in both the gallbladder and gastric mucosa.
An Evaluative Review of Mobile-assisted L2 Vocabulary Learning Approaches based on the Situated Learning Theory
Authors: Ye Shelly Xueting , Shi Jia , Liao Linyu
Published: March 2023

There is a growing trend of utilizing mobile technology to develop effective contextual vocabulary learning methods based on the situated learning theory (SLT). In spite of substantial research on mobile-assisted vocabulary learning (MAVL), there have been few reviews of MAVL approaches, let alone evaluations of them based on the idea of SLT. To address this research gap, this study evaluated three types of MAVL approaches: (1) mobile message services, (2) vocabulary learning applications, and (3) digital simulation games according to the authenticity principle and characteristics of SLT. The evaluative review included in-depth examinations of two aspects: the extent to which these characteristics are manifested in each approach, and the way in which these characteristics are incorporated into the design of each approach. The result suggests that the MAVL approaches differ significantly, in terms of their authenticity and degree of correspondence to the SLT. This review offers practical implications for the development and improvement of MAVL approaches, as well as important suggestions for future research, all of which are believed to benefit the field of L2 vocabulary acquisition.

Competition of Ethnic and National Languages within the Home Domain: Insights from Multilingual Sasak Family Language Choice, Lombok – Indonesia
Authors: Wilian Sudirman , Mahyuni Mahyuni , Fitriana Eka
Published: March 2023

Competition of languages in a bilingual/multilingual society is a prevalent phenomenon found anywhere in the world. Competition occurs when the choice of one language is supposed to be ‘prioritized’ and ‘prized’ over the other(s) in any domain of language use. This study explores how this phenomenon of language use occurs in the homeland of Sasak vernacular speakers living in the city of Mataram, Lombok–Indonesia.  The aim of this study was to investigate the extent to which family members of native Sasak inhabitants in Mataram use their own ethnic language in their daily interaction with their family members in the home, neighborhood, and friendship domains.  Data were collected through survey questionnaires, interviews, and participant observations by employing the concept of Fishman’s domain of language use, language attitude, and bilingualism. The obtained data were then selected, classified, and tabulated to compute the frequency of speech occurrences in each study group. The results show that participants displayed positive attitudes towards their mother tongue indicating that they were very proud of their first language. SL was almost always used in daily conversations in the home domain and neighborhood but the rate of use slightly differed among different age, education, and occupational groups. Societal bilingual patterns were portrayed in the stable use of both the indigenous language (SL) in the home domain and the national language (IL) in the official domain in education, government, or religious gatherings. Within the context of EGIDS by SIL, UNESCO developed from Fishman (1972) SL at present is still safe and maintained by its people.

Authors: Batista Fernanda Christie , Silva Mariana Paula da , Zotarelli Filho Idiberto José , Duarte Marcella Garcez
Published: March 2023

Introduction: The climacteric is the stage of life in which the transition from the productive or fertile period to the non-reproductive period occurs. Climacteric and menopause are intrinsically linked and may bring about various psychological and physiological changes. The use of medicinal plants (Herbal Medicine) is an important tool in an attempt to relieve symptoms. Objective: It was to develop a systematic review to present the main considerations and scientific evidence of the use of herbal medicines in climacteric and menopause to the reduction of symptoms and improvement of quality of life. Methods: The systematic review rules (PRISMA) were followed. The research was carried out from September to October 2022 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases, covering scientific articles from various eras to the present day. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 121 articles were found. A total of 32 articles were fully evaluated and 23 were included in this systematic review. Most studies showed homogeneity in their results, with I2 =96.7% >50%. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 30 studies with a high risk of bias and 37 studies that did not meet GRADE. An asymmetrical funnel plot does not suggest a risk of bias among small sample-size studies. In search of symptom relief and based on knowledge of the side effects of hormone replacement therapy, many women resort to alternative therapy with herbal medicines. The main results support that supplementation with soy isoflavones as a natural source of phytohormones is associated with a reduction in the frequency and intensity of hot flashes, a recurrent symptom in the climacteric. The formulated blend of four herbal extracts (Glycine max, Cimicifuga racemosa, Vitex agnus-castus, and Oenothera biennis) supports skin health and antioxidant status in women of menopausal age. Furthermore, purified pollen cytoplasm can be considered an effective non-hormonal treatment alternative for the treatment of vasomotor symptoms, as well as mood and sleep disturbances in peri and post-menopause. Three clinical trials using the Danggui Buxue Tang herbal formula have been shown to alleviate menopausal syndrome, providing solid scientific evidence of its effectiveness.

Published: March 2023

A 10-week feeding trial was conducted to evaluate the whole- body antioxidant status of silver carp fingerlings when fed with diets containing various organic acids. Five experimental diets were formulated, such as D1 containing no supplemented organic acids, while D2 contain (2%malic acid), D3 (2%citric acid), D4 (2% formic acid) and D5 (2% lactic acid). During the experiment, water quality parameters including temperature, pH and DO were controlled. Results showed that acidification of diet significantly reduced the activity of SOD, CAT and GPX throughout the body of silver carp fingerlings. Moreover, among different organic acid groups, the maximum value was observed in citric acid while, minimum value was recorded in formic acid. Data on whole -body antioxidant enzymes were subjected to one-way analysis of variance following Steel et al. (1996). Differences between among means were compared by Tukey`s Honestly Significant Difference Test and considered significant at (p<0.05) (Snedecor and Conhran, 1991).

Published: March 2023

A field experiment on LCC-based N management was carried out at Rajapur, Bardiya during the spring season of 2021 to determine the growth and productivity of spring rice varieties. The experiment was laid out in strip plot design with three replications. The treatment consisted of four varieties (Chaite-5, Hardinath-1, Hardinath 1-F1, and Hardinath-3) in horizontal plots and five levels of LCC-based N management practices (Pure LCC, 25% N (basal) + LCC, Recommended dose of fertilizer in three splits, Farmer’s dose, and no nitrogen) in vertical plots. The results showed that Pure LCC-based nitrogen management produced the highest grain yield (6.24 t ha-1) followed by 25% N basal +LCC (5.77 t ha-1). LCC-based treatments produced a significantly higher yield than recommended dose applied in three splits. The higher yield in pure LCC was because of higher yield attributes like effective tillers m-2, higher thousand-grain weight, lower sterility percentage, longer panicle length, and higher panicle weight. Hardinath-3 and Hardinath 1-F1 with pure LCC produced significantly higher yields than other treatment combinations. The spring rice varieties Hardinath 1-F1 and Hardinath-3 were high yielders than Hardinath-1 and Chaite-5. The higher yield of Hardinath-3 was due to higher number of effective tillers m-2, longer panicle length, and higher panicle weight. Similarly, the higher yield of Hardinath1-F1 was mainly due to higher thousand-grain weight and higher number of effective tillers m-2 as compared to other varieties except for Hardinath-3. The varieties Hardinath 1-F1 and Hardinath-3 with pure LCC-based N management were high-yielders in Bardiya-like climatic conditions.

Published: March 2023

To explore the path identification of marketing risk factors in small and medium-sized energy enterprises, this study extracts 16 factors influencing marketing from 3 aspects of the external environment, internal management and information feedback through literature analysis and expert interviews. In this paper, the interpretative structural model (ISM) is used to construct the multi-level structural diagram of influencing factors and the influencing factors are divided into three layers: direct factors, intermediate factors and fundamental factors. Then the matrix impact of cross multiplication applied to classification (MICMAC) is used to analyze the factors affecting the risk of small and medium-sized energy enterprises, and then the driving force and dependency classification diagram of marketing risk factors is drawn. The results show that the dependence and driving force of financing risk, partners, marketing personnel and other factors are relatively weak, and risk treatment can be prioritized. The factors such as lack of policies, sudden factors and organizational structure have high driving forces, which are the key factors that constitute the marketing risks of energy enterprises, and should be focused on. This study takes the marketing risk factors of small and medium-sized energy enterprises as the research object, and the research results have certain universality, which can provide new solutions for small and medium-sized energy enterprises to face marketing risks.
Extrapolation of Crude Oil Futures Implied Return by Black Scholes Model and Monte Carlo Simulation
Authors: Shi Chengmin
Published: March 2023

Since the global COVID-19 outbreak in 2020, central banks around the world have adopted loose monetary policies to hedge against the downward pressure on the economy through quantitative easing. With the gradual increase in the number of currencies, from the beginning of 2022, global commodity prices began to rise continuously. Among them, the price of fossil fuels such as oil has hit record highs due to the intensification of geopolitical conflict between Russia and Ukraine. During this period, as the divergence in oil prices intensified, speculation opportunities in the derivatives market also emerged one after another. [1] Therefore, in this article, the principles of two pricing models, the Black Scholes Model and the Monte Carlo Model, are used to predict the price trend of Crude oil in the future. The implied volatility calculated according to the Black Scholes model will be used as the volatility of the oil futures price trend in the Monte Carlo model, and the current option premium will be used to reverse the implied return in the Monte Carlo simulation. It serves as a forecast of future yields for oil futures. By using the data from March to September 2022, the correlation coefficient between the predicted return and the actual return is 0.67, which is a relatively convincing prediction accuracy. However, the volatility of the predicted return will be higher than the actual return due to factors such as the volatility smile.

By comparing and contrasting the data under ideal situation and real cases, it reaches to the conclusion that the investors do gain higher returns and more optimized portfolio by means of the Markowitz Model.
The Impact of EU Carbon Border Adjustment Mechanism: Perspective from Developed and Developing Countries
Authors: Peng Xiaorui
Published: March 2023

In recent years, the environmental problems which have a direct effect on the daily life and health triggered by human activities are gradually being exposed. Exploring sustainable development becomes the priority. In December 2019, European Union proposed European Union Carbon Border Adjustment Mechanism – Carbon border adjustment levy imposed on some European Union imports, included imported iron and steel, aluminum, fertilizers, and electricity, etc. If this policy is formally implemented, it will inevitably have an impact on the global import and export trade pattern, especially in some major exporters of carbon-intensive products. This paper presents a systematic analysis of the impact of EU CBAM on developed and developing countries. The results show that developed countries are relatively less vulnerable to EU CBAM due to earlier implementation of environmental protection policies and similar carbon pricing levels to the EU. In contrast, poor carbon policy environment and slow development of low-carbon technologies and carbon trading markets is inescapable presences in the developing countries, so the impact is greater. Under the challenge of EU CBAM, it is suggested that all countries accelerate the pace of promoting the construction of carbon emission trading market and a sound carbon pricing system. At the same time, help enterprises to make green transformation and find diversified international trade policies.

Analysis of Ice Cream Industry Market Issues and Prospects: Example from the Chinese Market
Authors: Liu Yi
Published: March 2023

The “ice cream assassin” was one of China’s Internet buzzwords in June-July this year, reflecting consumer dissatisfaction with overpriced ice creams in freezers that did not indicate their price. After the phenomenon festered online, the Chinese government introduced policies to curb the mess. China lacks a leading local high-end ice cream brand, and large companies such as “Zhong Xue Gao” have not established brand awareness in the minds of consumers. After consumers have experienced a “deceptive purchase”, it is challenging to repurchase related products. The critical factor for the survival of such a business model is that, in addition to the huge profit margin, it also reflects consumers’ demand for cultural and social levels. In the case of consumer demand and market supervision, China’s local high-end ice cream is expected to emerge as a leading local company to compete with foreign companies such as Haagen-Dazs.

Authors: Shen Shunning
Published: March 2023

Considering the dominance of the United States Dollar and the background of the global weak economy hindered by covid-19 as well as the tangled geopolitics, it is essential to analyze how the fed’ announcements affect the world. This article explores how the key macroeconomic indicators changed before and after the fed rate hikes and look into the mechanisms behind it. The result shows that global liquidity does not see a rapid change; commodities prices do exist a negative correlation with the U.S. interest rates, explained by the holding cost of inventories. In terms of the effect on China, the short-term cross-border capital outflow is positively related to the China-US spread; meanwhile, currency devaluation is happening. China’s response to such shocks is not consistent with the idea that other worlds outside the U.S. need to increase the interest rate to keep pace with the fed reserve announcement. Rather, the People's Bank of China decreases its one-year loan prime rate from 3.70 to 3.65 percent in August 2022. To prevent capital outflows and currency devaluation, capital control takes place. On August 27, 2022, Jay Powell, the chair of the US Federal Reserve, declared that taming the surging inflation was the priority despite the cost for households and businesses. It is expected that the fed reserve will continue its tight monetary policy, so emerging economies like China should be prepared for it.

Published: March 2023

The conflict between Russia and Ukraine at the start of 2022 has largely influenced the global market, both the commodity market and stock market. Russia, as a major exporter of oil, has been sanctioned by the western countries which led to a sharp rise in the price of the crude oil. And the global capital market was affected consequently. This paper uses the Shanghai Stock Exchange Composite and the Shenzhen Stock Exchange Component Index in the Chinese market, and the Dow Jones Industrial Average, the Standard & Poor’s, and the National Association of Securities Dealers Automated Quotations in the American market to assess the impact of the geopolitical risk. Using these indices, this paper builds a VAR model to analyze the interaction of the index value and the oil price within a system, and to predict the further influence of the fluctuation in the price of the crude oil on the security market. An ARMA-GARCH model is also built to find out the change in stock market volatility induced by the oil price. This paper finds that the war-induced rise in the price of crude oil has a negative impact on the return of the security market both in China and the US while having little influence on the volatility.
