This study seeks to examine the relationship between business resources (through VRIN: Valuable - valuable, Rare - scarce; Inimitable - difficult to adapt, Irreplaceable - hard to replace), dynamic capability, external cooperation, and efficiency of startups operating in the seafood export sector. Research data was collected randomly and conveniently from 250 enterprises in Ba Ria-Vung Tau province, Vietnam, from October 2020 to December 2020. After excluding those ineligible, the remaining 204 enterprises meet the research conditions. With the support of SPSS-AMOS 22 dedicated software, using the 5-step Likert scale and Structural Equation Modeling (SEM), the study conducted analysis steps such as verifying convergence, discriminant value, unidirectional and scale reliability when giving the components correlated freely in the critical model by Confirmatory Factor Analysis (CFA) analysis. Results of the study have shown that the enterprise resource factor - VRIN has a positive impact on dynamic capability, and outside cooperation. However, in contrast to previous studies, we found that the relationship between enterprise resources - VRIN and performance as well as the relationship between dynamics capacity and performance is not clear. This shows that seafood exporters need to promote, exploit and effectively use this precious resource to improve business efficiency.

Livelihood capitals have a clear influence on livelihood development. As for the livelihood results, it has been pointed out in the analysis of the poor households that the ability of people to escape poverty depends especially on the access to livelihood capitals. This study aims to analyze the impacts of livelihood capital on poverty among mountain people who depend on forests through human capital, social capital, natural capital, physical capital and financial capital. This research employs the model of binary regression function. Independent variables x1, x2, …, xn are targets of livelihood strategy, vulnerability context, and livelihood capitals. These variables were selected to be included in the original model with dependent variable Y as poor and non-poor households. This study surveys households living in upland areas, near forests, and households of ethnic minorities. The results show that,out of the poor household rate, nearly 4% are newly-poor households or those falling back into poverty. Therefore, the government needs to pay more attention to this disadvantaged group and implements policies such as education and training policies, credit support policies, policies to support forest development, and payment for forest environmental services in the context of emerging countries like Vietnam.

Some Features of The "Vietnamization" of Confucianism in The History of Vietnam

( Nguyen Tai Dong ) 충남대학교 유학연구소 2015 儒學硏究 Vol.33 No.-

본 논문에서는 베트남유학에 담겨 있는 특별한 요소들을 살펴본다. 유학은 본래 베트남고유의 사상체계는 아니다. 그러나 유학은 2000년 동안 베트남의 민족사상 체계 속에 점진적으로 뿌리를 내렸으며 베트남의 발전과 함께 하였다. 이로써 유학은 마침내 베트남문화 발전에 기여를 하게 되어 베트남 유교가 되었다. 유학의 베트남화 과정은 오랜 시간동안 계속 전개되었다. 베트남 학자들 역시 중국유학의 개념들을 사용하였는 바, 대체로 송나라 유학의 개념을 사용하였다. 그러나 베트남 학자들은 중국유학의 몇 가지 특수한 개념들만을 취사선택하고 그것을 핵심으로 가져와 중국유학의 개념체계와는 다른 유학체계를 만들었다. 또한 베트남 유학과 중국 유학을 비교해 볼 때, 이러한 유학의 개념들에 대해 해석하는 방법이 다르다. 유학의 베트남화 과정에 있어서의 주요한 특징들은 다음과 같이 요약할 수 있다. (1) 외래 사상과 문화는 베트남의 실제적 상황 아래 베트남 민족의 질문에 대답을 해야만 존재하고 발전할 수 있다. (2) 베트남 사람들은 외래문화를 수입하였지만 여전히 베트남문화의 본질을 지켰다. (3) 인문주의와 인간존중이 발휘되는 바탕 위에서 ‘베트남화’가 실현될 수 있다. (4) 베트남화 과정은 실용주의적인 성격을 지닌다. 어떠한 이론이든 간에 실천을 함께 수반하는 경향이 있다. (5) 베트남화 과정은 개방성과 문화적 다원성과 사상의 독선을 거부하는 경향을 바탕으로 전개된다. (6) 외래 사상과 문화를 수용할 때 베트남 사람들은 극단적이지 않고 비판적 정신을 견지한다. In this paper, the author considers some distinguished features of Vietnamese Confucianism. Confucianism was originally not an indigenous theoretical system in Vietnam, but in about 2000 years of introducing and developing in this country, it has gradually taken root into Vietnamese theoretical tradition and made an important contribution to its florescence. The process of ‘Vietnamization of the Confucianism’ took place during that long time. Vietnamese scholars also used original Confucian concepts and ideas, mainly the Neo-Confucian ones, but they chose only some of those concepts, considering them key concepts, and based on them they established a system more or less different from Chinese Confucianism. Furthermore, in explaining those concepts’ connotations, Vietnamese Confucianism was not similar to Chinese Confucianism. Some distinctive features of the Vietnamization of Confucianism are as follows: (1) Foreign theories and cultural factors could exist and develop if and only if they were based on Vietnamese reality and used in order to answer problems emerged from it. (2) Foreign culture was accepted, but the characteristics of the indigenous culture were well preserved. (3) “Vietnamization” was based on the confirmation of humanism. (4) The process of Vietnamization was realistic, every theory tended to the close connection with the reality. (5) “Vietnamization” was based on the open-minded and multiculturalist spirit and inclined to avoid monopoly of thought. (6) The Vietnamese are not fanatic: they show their critical spirit when acquiring foreign thoughts and cultures.

This study performed phytochemical and bioactiveassessments of the mangrove Lumnitzera racemosaWilld. leaves. Bioassay-guided fractionation of the methanolicextracts led to the identification of thirty-six compounds(1–36), their structures were elucidated using detailed NMRspectroscopic and MS analysis. The extracts, fractions, andthe isolated compounds were screened for potential antioxidantand cytotoxic activities. Antioxidant assays wereperformed using peroxyl radical-scavenging and reducingassays, whereas cytotoxicity was measured using MTTassays in HL-60 and Hel-299 cell lines. The methanolicextract, CH2Cl2 and n-BuOH fractions (10.0 lg/mL)exhibited potent antioxidant activity, with Trolox equivalent(TE) values of 24.94 ± 0.59, 28.34 ± 0.20, and27.09 ± 0.37 (lM), respectively. In addition, the isolatedcompounds exerted cytotoxic effects in a dose-dependentmanner; compounds 1 and 14 exhibited the most potentcytotoxicity in HL-60 cells, with IC50 values of 0.15 ± 0.29and 0.60 ± 0.16 lM, respectively. To clarify the mechanism(s) behind these cytotoxic effects, we measured thetime-dependent changes in apoptotic markers including thecondensation and fragmentation of nuclear chromatin, andthe downregulation of p-ERK1/2, p-AKT, and c-Myc levels.

Application of Electrocoagulation for Printing Wastewater Treatment: From Laboratory to Pilot Scale

Thuy, Nguyen Thi,Hoan, Nguyen Xuan,Thanh, Dang Van,Khoa, Pham Minh,Tai, Nguyen Thanh,Hoang, Quang Huy,Huy, Nguyen Nhat The Korean Electrochemical Society 2021 Journal of electrochemical science and technology Vol.12 No.1

This study reports for the first time the application of electrocoagulation (EC) from laboratory to pilot scales for the treatment of printing wastewater, a hazardous waste whose treatment and disposal are strictly regulated. The wastewater was taken from three real printing companies with strongly varying characteristics. The treatment process was performed in the laboratory for operational optimization and then applied in the pilot scale. The weight loss of the electrode and the generation of sludge at both scales were compared. The results show that the raw wastewater should be diluted before EC treatment if its COD is higher than about 10,000 mg/L. Pilot scale removal efficiencies of COD and color were slightly lower compared to those obtained from the laboratory scale. At pilot scale, the effluent CODs removal efficiency was 81.9 - 88.9% (final concentration of 448 - 992 mg/L) and color removal efficiency was 95.8 - 98.6% (final level of 89 - 202 Pt-Co) which proved the feasibility of EC treatment as an effective pre-treatment method for printing wastewater as well as other high colored and hard-biodegradable wastewaters.

Ultralow-Power Ku-Band Dual-Feedback Armstrong VCO With a Wide Tuning Range

Tai Nghia Nguyen,Jong-Wook Lee IEEE 2012 IEEE transactions on circuits and systems. a publi Vol.59 No.7

<P>Here, we investigate the design of a Ku-band Armstrong voltage-controlled oscillator (VCO) utilizing dual transformer feedback for low-voltage low-power operation. The primary transformer feedback between the drain and the source of the VCO increases the output voltage swing under low supply voltage. With the secondary transformer feedback, g_m-boosting is obtained by the coupling between the drain and the gate of the Armstrong VCO. Combined with transformer feedback, g_m-boosting further reduces the negative transconductance required for oscillation startup, enabling ultralow-power operation. Thus, the proposed Armstrong VCO with dual feedback operates at 0.4 V with power consumption as low as 600 W. Under this condition, the measured phase noise of the VCO is -100.6 dB/Hz at 1-MHz offset from a 14.1-GHz carrier. The results show that the proposed VCO is suitable for very low-power applications requiring high signal purity.</P>
