Recently, vegetarian diets have experienced a dramatic increase in popularity. The aim of the study is to explore and test the relationship between the factors influencing consumers' dietary decisions in Ho Chi Minh City, Vietnam. The questionnaire applied a five-point Likert scale to investigate factors that affect Ho Chi Minh City's citizens when they have a vegetarian diet. 497 respondents (68% female; 61.2% aged 18-22; 82.7% had regular vegetarian diets) living in Ho Chi Minh City took part in both online and offline surveys. The results were processed by SPSS 22.0 software. The reliability was checked by Cronbach Alpha and Exploratory factor analysis (EFA) to identify the underlying relationships between measured variables. The Correlation analysis was implemented to show how strong and degree of two variables are related to each other before the multivariate regression equation was analyzed. The result showed the Five factors that were motivating people in Ho Chi Minh City to decide on plant-based diets, such as Animal Welfare, Health, Religion, Mood, and Reference groups. The mood is the most influential variable that significantly influences people's food choices. Attitudes toward vegetarian diets are changing. Therefore, recognizing the trends in food consumption might help companies take advantage of investment opportunities and build their marketing strategies.

Mn₃Ga has drawn interest in spintronics for potential applications due to large perpendicular magnetic anisotropy, high Curie temperature (~760 K), and low magnetization. Motivated by previous studies on tunability of magnetism through transition metal substitutions in Mn₃Ga, we investigate magnetic and structural properties of Mn₃Ga upon Co substitution using first-principles calculations. In the absence of Co, Mn₃Ga is in tetragonal phase. With Co, both tetragonal and cubic phases occur. x ≤ 0.5, tetragonal phase is preferred, while x > 0.5, cubic one is favored. Co magnetic moment in two phases exhibit different magnetic behaviors. In tetragonal phase, unlike other Co compounds, Co magnetic moment nearly vanishes. On the other hand, in cubic phase, it retains a usual moment at about 1 μB. Nearly vanishing Co magnetic moment in tetragonal structure is elucidated phenomenologically by the magnetic exchange coefficient, where coupling between Co and Mn is much smaller than cubic one. Furthermore, anomalous Hall conductivities (AHC) are investigated for x = 0, 0.5, and 1. The magnitude of AHC is about 100~500 S/cm, where the sign change occurs at 0.5 < x < 1.

Ufd1 phosphorylation at serine 229 negatively regulates endoplasmic reticulum-associated degradation by inhibiting the interaction of Ufd1 with VCP

<P>Misfolded proteins in the endoplasmic reticulum (ER) are removed through multistep processes termed ER-associated degradation (ERAD). Valosin-containing protein (VCP) plays a crucial role in ERAD as the interaction of ubiquitin fusion degradation protein 1 (Ufd1) with VCP via its SHP box motif (<SUP>228</SUP>F-S-G-S-G-N-R-L<SUP>235</SUP>) is required for ERAD. However, the mechanisms by which the VCP–Ufd1 interaction is regulated are not well understood. Here, we found that the serine 229 residue located in the Ufd1 SHP box is phosphorylated <I>in vitro</I> and <I>in vivo</I> by cyclic adenosine monophosphate-dependent protein kinase A (PKA), with this process being enhanced by either forskolin (an adenylyl cyclase activator) or calyculin A (a protein phosphatase inhibitor). Moreover, a phosphomimetic mutant (S229D) of Ufd1 as well as treatment by forskolin, calyculin A, or activated PKA strongly reduced Ufd1 binding affinity for VCP. Consistent with this, the Ufd1 S229D mutant significantly inhibited ERAD leading to the accumulation of ERAD substrates such as a tyrosinase mutant (C89R) and 3-hydroxy-3-methylglutaryl coenzyme A reductase. However, a non-phosphorylatable Ufd1 mutant (S229A) retained VCP-binding ability and was less effective in blocking ERAD. Collectively, our results support that Ufd1 S229 phosphorylation status mediated by PKA serves as a key regulatory point for the VCP–Ufd1 interaction and functional ERAD.</P>

International payment is an essential part of the economy, which is beneficial to both commercial banks and trading enterprises. Moreover, service quality, which has been a key point of discussion for decades, relates to customer satisfaction. This study aims to investigate the factors influencing international payment service quality at the Join Stock Commercial Bank for Investment and Development of Vietnam (BIDV) from 2015 through 2019. This research deploys both quantitative and qualitative methods to discuss the effects of these components. Statistical data was examined through different tests, including reliability analysis, correlation, and regression analysis by SPSS 16.0. The authors obtain and analyze 157 valid responses from customer surveys, then by applying an integration SERVPERF and PSQM model, identify five main components: Reliability, Tangibles, Assurance, Convenience, and Responsiveness, which explain how the customer perceives the service quality of international payment activities at BIDV. The results show that these five factors have a positive relationship with service quality, in which, Reliability has the most significant impacts on service quality level. Besides, the findings not only contribute to the literature but also give some practical implications for BIDV to improve its international payment service quality and help them to obtain customer satisfaction in the fast-changing environment.

Efforts to reduce tobacco use among school children need to be based on understanding of access to cigarettes by these subjects because previous studies indicated that enforcement of laws for controlling tobacco sales seems to not affect teen/school children because they can obtain cigarettes from different sources. This paper aims to describe access to and availability of cigarettes among school students (aged 13-15 years old) according to the data from GYTS Vietnam 2014. In GYTS, a national school-based survey of students of grades 8-10, our findings showed that about 15% school children are current smokers who smoke at home, and that they could easily buy cigarettes from stores (63.2%), or someone else (27.8%), or street vendors (9%). Notably, over 85% of school children answered that they were not refused because of their age. This high percentage was nearly the same in the North (85.7%), the Centre (92.5%), and the South (89.7%) of Viet Nam. These findings show that it is quite easy for school children to obtain cigarettes and this is a crucial challenge for policy makers aiming to reduce tobacco use among youth in general and school-age students in particular.

Inhibition of Melanosis in Whiteleg Shrimp (Litopenaeus vannamei ) during Refrigerated Storage Using Extracts of Different Avocado (Persea americana Mill.) By-Products

Melanosis in shrimp usually leads to reduction in its shelf life and quality, which causes a significant loss in economic value of shrimp products. This study reports potential applications of nine ethanolic extracts of by-products, i.e., peel and/or seed from three Vietnamese avocado varieties as effective inhibitors of melanosis in whiteleg shrimp. Six out of nine shrimp samples treated with the prepared extracts (0.025%, w/v) reduced melanosis and lipid oxidation more significantly as compared to those treated with sodium metabisulfite (SMS, 1.25%, w/v) and control groups (treated with water) during 8-day storage at 4oC (P<0.05). These six extracts had mean gray values ranging from 47.0±0.7 to 57.3±0.4% were lower than those treated with SMS (mean gray of 39.8±0.4%). The inhibition of melanosis and lipid oxidation in shrimp for these extracts could be attributed to their high content of polyphenols [total phenolic content (TPC) from 44.5±1.1 to 144.7±1.9 mg gallic acid equivalents/g dried weight] and strong antioxidant activities [including 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, ferric reducing antioxidant power (FRAP), and tyrosinase enzyme inhibition]. Pearson statistical analysis showed strong correlation for melanosis inhibition to TPC and DPPH scavenging (r>0.80) followed by tyrosinase inhibition and FRAP (r>0.50). The findings obtained from this study suggest potential utilization of avocado by-product extracts as safe and cheap natural alternatives to traditional sulfites for anti-melanosis and shelf life extension of whiteleg shrimp.

베트남 학습자를 대상으로 한 한국어 이유·원인 연결형 문법 항목의 난이도 위계화 연구

응웬 티 꾸잉안(Nguyen Thi Quynh Anh) 한국어교육연구학회 2020 한국어교육연구 Vol.- No.13

본 연구는 베트남인 한국어 학습자를 대상으로 한 한국어 이유·원인 연결형 문법 항목을 위계화하는 데에 목적이 있다. 본 연구에서는 각 문법 항목의 통사적 특징 제약에 대해 베트남어와 대조분석을 하고, 베트남인 한국어 학습자에 각 항목에 대한 체감 난이도 및 사용빈도 조사를 진행함으로써 계량적 위계화 목록을 제안하고자 한다. 이를 위해 본 연구에서는 다음과 같은 연구절차 및 방법을 사용하였다. 첫째, 이유 원인을 나타내는 인과관계 연결형 문법 항목을 선정하기 위해 최근에 베트남 내 대학에서 많이 사용하고 있는 5종의 한국어교재들과 ‘국제통용 한국어 표준 교육과정 모형 4단계’에서 제시하고 있는 이유·원인을 나타내는 항목들 모두 추출하여 중복도 조사를 하였다. 중복도 조사를 통해 평균 중복도가 5.77로 나타난 것으로 확인하였고 평균 중복도보다 높은 중복도를 갖는 문형을 중요한 항목으로 보아, 평균 중복도 6 이상인 문법 항목들을 선정하였다. 둘째, 이유·원인 문법 항목의 난이도를 측정하기 위해 내적 난이도와 외적 난이도를 분석하였다. 외적 난이도 경우, 선정된 각 항목의 통사적 제약의 수를 조사하고 베트남어와 대응 분석하여 대응 양상을 수치화하였다. 내적 난이도의 경우, 베트남인 한국어 학습자 입장에서 이유·원인 문법 항목에 대한 난이도를 측정하는 것이다. 이를 위해 베트남 내 대학에서 한국어를 전공하는 베트남 학습자를 대상으로 각 문법 항목의 난이도 및 사용빈도 조사를 진행하였다. 마지막으로 조사를 통해 계산된 각 항목의 난이도 값에 따른 위계화 목록을 제안하였다. 본 연구에서는 베트남 학습자가 느끼는 체감 난이도와 대조분석을 통한 통사적 제약의 수에 의한 난이도를 분석하는 데에 의의를 둔다. This study aims to select and hierarchy the Reason and Cause Connective Expressions for Vietnamese Korean learners in Vietnam Universities. To meet this goal, we collected and selected a list of 15 educational items based on redundancy surveying the reason and cause connective Expressions in Korean textbooks. Thus in order to measure the difficulty of each item, it is required to find difficult of the expressions of reason and cause. The difficult of the grammatical item was made from two factors: internal factor(the difficulty that Vietnamese learners experiencing) and external factor(the syntactic features patterns of responses to Vietnamese). In order to measuring the internal factors we analyzed the difficult that Vietnamese learners experiencing. With external factors, we analyzed the syntactic feature of each items and contrast with Vietnamese. Therefore basing on the average value of each item, a list of hierarchy of the reason and cause connective expressions was suggested as follows. The lack of study is that we can not analyze all of expressions of reason and cause. Lastly, we hope that study could contribute to Korean grammar education for Vietnamese learners.

Ant and silkworm pupae as convenient diets for the development and reproduction of big-eyed bug Geocoris ochropterus (Hemiptera: Geocoridae)

Ngoc Bao Chau Nguyen,Quynh Phuong Anh Nguyen,Thuy To Nhu Le,Thi Phung Kieu Nguyen,Bao Quoc Nguyen 한국응용곤충학회 2021 Journal of Asia-Pacific Entomology Vol.24 No.2

We investigated the influence of convenient diets on big-eyed bug Geocoris ochropterus. Development and reproduction of G. ochropterus fed on convenient diets of ant pupae Oecophylla smaragdina and silkworm pupae Bombyx mori were examined using aphids Aphis gossypii as the control diet. Results showed that Geocoris ochropterus nymphs completed development to adults on all diets. Total average development period was 35.1 days fed on ant pupae, 35.9 days fed on silkworm pupae, and 36.0 days fed on aphids. Head width, body length, forewing length, and fresh body weight of adults were not affected by diets, except for females reared on ant pupae that were significantly heavier than those fed on aphids. There was no significant difference in offspring sex ratio. Total number of eggs deposited per female fed on ant pupae was significantly larger than when fed on aphids, while eggs laid by females fed on silkworm pupae were significantly longer than eggs laid by females fed on aphids. Results suggest that ant pupae and silkworm pupae could be effectively used for mass rearing of G. ochropterus.
