An Introduction to Immigration Laws of Vietnam

Ngo,Huy Cuong 한국입법정책학회 2010 입법정책 Vol.4 No.2

베트남이 통일된 지 36년이 지났다. 통일 당시 해외로 도피했던 교민들이 이제는 해외에서 형성한 부를 모국 베트남의 국가건설 에 투자하면서 자신의 정체성을 찾고자 한다. 2010년 현재 베트남 의 해외교민 4백30만 명 중 약 3백만 명 이상이 북미에 거주하고 있다. 이들은 베트남 전쟁 후 이주한 세대와 그 자손들이 대부분 인데, 베트남 정부는 해외교민을 ‘과거에 집착해서 큰 것을 놓치 면 안 된다’는 철저한 실용주의 원칙으로 대하고 있다. 베트남 부 는 민족이라는 기치아래 국가발전을 위한 베트남인의 대단결을 호소하고 있으며 해외교민의 국내 투자와 국내귀국을 독려하고 있다. 베트남정부는 베트남을 출입국 및 통과하는 외국인들에게 최상 의 환경을 제공하며; 베트남 법률과 베트남이 국제조약에 맺은 규 정에 의하여 베트남에 거주하는 외국인의 생명, 재산, 권리 및 기 타의 이익을 보호하도록 규정하고 있다. 베트남에 출입국, 통과, 거주하는 외국인은 베트남의 전통, 풍습, 습관 및 베트남의 법을 준수하고 존중해야 한다. 베트남의 출입국, 통과, 거주가 법률위반 을 위한 목적으로 이용되는 것을 엄격히 금하고 있으며 외국인 출입국, 통과, 거 주에 관하여 베트남이 국제조약에서 맺은 규정과 이 법령 규정사이에 차이가 있다면 국제협정규정이 우선하도록 하고 있다. 외국인은 신고한 입국목적과 맞게 외국인 왕래금지 구역을 제 외하고 베트남 영토 내에 자유스럽게 다닐 수 있다. 금지구역에 출입하려면 금지구역을 관리하는 정부심사기관의 허가를 받아야 한다. 또한 장기체류 외국인은 공안부 출입국관리기관에서 장기체 류증을 발급 받는다. 이 장기체류증을 소지한 자는 베트남 출입국 시 비자가 면제된다.

Thuy Dung PHAM THI1,Anh Tin NGO2,Nam Tien DUONG3,Van Kien PHAM4 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.5

The purpose of this study is to evaluate the impact of organizational culture on job satisfaction and organizational commitment among employees in small and medium-sized enterprises in Ho Chi Minh City, Vietnam. The study hypothesized that organizational culture has a significant influence on employees’ satisfaction and that satisfaction also significantly impactsorganizational commitment among employees. The data are collected from a sample of 240 office employees. Structural Equation Modeling is used to determine the influence of organizational culture dimensions,including open working environment, salary, and rewards, empowerment, management style, corporate values, on employees’ satisfaction and organizational commitment. The findings showed that the five dimensions of organizational culture positively impact employees’ satisfaction and that job satisfaction significantly influences organizational commitment. Thus, job satisfaction serves as the bridge between organizational culture and commitment. The current study contributes to providing a practical insight into the relationships between organizational culture, employees’ job satisfaction, and organizational commitment. Based on that, managers can develop suitable personnel policies for their organizations to simultaneously enhance employees’ performance and satisfaction, which makes them stay with the company.

The Role of Non-Governmental Organizations in the Climate Change Response Policies in Ho Chi Minh City, Vietnam

Ngo Hoai Son,김판석 한국외국어대학교 동남아연구소 2023 東南亞硏究 Vol.33 No.2

NGOs play a crucial role in climate change response strategies in Vietnam through their involvement in policymaking. This study reviews the areas of NGO engagement in climate change policies in the context of Ho Chi Minh City, and presents suggestions for improving their participation. Based on the theory of climate services, it employed a content analysis technique using NVivo 11 software to examine the participation of 30 registered NGOs. The results indicate that engagement in climate change response policies is comparable to that reported in other studies on the same topic. NGO participation in the implementation of climate change response policies focuses primarily on policy lobbying, community capacity building, research and consultation, and livelihood development. NGOs have played a crucial role in assisting and supporting the most severely affected communities by helping people consolidate and enhance their capacity to adjust to the effects of climate change through adaptation measures, disaster preparedness, and capacity building.

The Cham (Champa) Traders and the Trade Route from the Central Coastal to the Highland of Vietnam

Ngo Van Le 조선대학교 국제문화연구원 2015 국제문화연구 Vol.8 No.2

It is not found any previous study on the Cham traders and the trade routes from the Central Coast to the Highlands of Vietnam. Taken just few scattered and related ancient documents, the authors have conducted some field surveys and researches of the local ethnic groups in the Highlands since 2013. Their moves aim at learning about the relationships and the trade routes connecting the Cham people and other ethnic minority people in the Central Highlands. The article is considered as one of the initial research outcomes. In this article, we identify the evidence of the Cham-Thuong relationships and their trade routes. It is the route along the main rivers, in parallel with the French-build railway in Highland and plenty of roads explored by both the minority people and Cham people through the historical periods.

Discovery of New Triterpenoid Saponins Isolated from <i>Maesa japonica</i> with Antifungal Activity against Rice Blast Fungus <i>Magnaporthe oryzae</i>

Ngo, Men Thi,Han, Jae Woo,Yoon, Sunggeon,Bae, Sohyun,Kim, Soo-Young,Kim, Hun,Choi, Gyung Ja American Chemical Society 2019 Journal of agricultural and food chemistry Vol.67 No.27

<P>While searching for new antifungal compounds, we revealed that a methanol extract of plant species <I>Maesa japonica</I> has a potent antifungal activity <I>in vivo</I> against rice blast fungus <I>Magnaporthe oryzae</I>. To identify the antifungal substances, the methanol extract of <I>M. japonica</I> was extracted by organic solvents, and consequently, six active compounds were isolated from the <I>n</I>-butanol layer. The isolated compounds were five new acylated triterpenoid saponins including maejaposide I (<B>1</B>), maejaposides C-1, C-2, and C-3 (<B>2</B>-<B>4</B>), and maejaposide A-1 (<B>5</B>), along with a known one, maejaposide A (<B>6</B>). These chemical structures were determined by NMR and a comparison of their NMR and MS data with those reported in the literature. Based on the <I>in vitro</I> antifungal bioassay, the five compounds (<B>2</B>-<B>6</B>) exhibited strong antifungal activity against <I>M. oryzae</I> with MIC values ranging from 4 to 32 μg/mL, except for maejaposide I (<B>1</B>) (MIC > 250 μg/mL). When the compounds were evaluated at concentrations of 125, 250, and 500 μg/mL for an <I>in vivo</I> antifungal activity against rice blast, compounds <B>2</B>-<B>6</B> strongly reduced the development of blast by at least 85% to 98% compared to the untreated control. However, compound <B>1</B> did not show any <I>in vivo</I> antifungal activity up to a concentration of 500 μg/mL. Taken together, our results suggest that the methanol extract of <I>M. japonica</I> and the new acylated triterpenoid saponins can be used as a source for the development of natural fungicides.</P> [FIG OMISSION]</BR>

<P><B>Abstract</B></P> <P>Highly biocompatible phenylboronic acid-functionalized graphitic carbon nitride quantum dots (g-CNQDs/PBA) were prepared by a simple hydrothermal process and used as a glucose sensing fluorescence material. Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and transmission electron microscopy were used to characterize chemical and physical structures of g-CNQDs/PBA. The quantum yield (QY) of g-CNQDs/PBA was as high as 67% when measured using quinine sulfate as a standard, which is the highest QY value ever reported for fluorescent g-CNQDs. The g-CNQDs/PBA exhibited two wide linear regions in the range of 25 nM – 1 μM and 1 μM – 1 mM with a detection limit as low as 16 nM. In addition, it showed excellent selectivity in the presence of various interfering reagents as well as very low cellular toxicity and excellent bio-imaging properties. Overall, the g-CNQDs/PBA fabricated in this study can be a promising candidate for a range of clinical diagnostics and biomedical applications.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Highly biocompatible g-CNQDs/PBA is fabricated through a simple hydrothermal process. </LI> <LI> The obtained material shows the highest quantum yield ever reported based on g-CNQDs. </LI> <LI> The g-CNQDs/PBA exhibits high sensitivity towards glucose with a very low detection limit. </LI> <LI> The g-CNQDs/PBA displays excellent bio-imaging features and low cytotoxicity. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>The g-CNQDs/PBA fabricated in this study exhibits highly biocompatible and excellent glucose sensing properties.</P> <P>[DISPLAY OMISSION]</P>

Ngo, Duc Tung,Le, Hang T. T.,Pham, Xuan-Manh,Jung, Ji-Won,Vu, Ngoc Hung,Fisher, John G.,Im, Won-Bin,Kim, Il-Doo,Park, Chan-Jin The Royal Society of Chemistry 2018 Journal of materials chemistry. A, Materials for e Vol.6 No.6

<P>Porous Si is considered a potential anode material for next-generation Li-ion batteries (LIBs) because of its high specific capacity, low lithiation/delithiation potential, low cost, and environmental friendliness. In this work, we introduce a simplified Mg-thermal-reduction method for the production of mass-scalable coral-like bulk-Si powder with a high surface area (38 m<SUP>2</SUP> g<SUP>−1</SUP>), broad pore-size distribution (2-200 nm), and 3-dimensionally (3D) interconnected Si structure for application in LIBs. The porous, coral-like Si electrode delivered a high reversible capacity of 2451 mA h g<SUP>−1</SUP>, corresponding to ∼70% of the theoretical capacity of Si, at a rate of C/10. After 100 cycles, the porous, coral-like Si electrode maintained a capacity of 1956 mA h g<SUP>−1</SUP>, corresponding to 79.8% of the initial reversible capacity. Importantly, a reasonably high reversible capacity of 614 mA h g<SUP>−1</SUP> was achieved even at a high rate of 10C. These outstanding results demonstrate that the 3D-networked, porous, coral-like Si powder, synthesized <I>via</I> a NaCl-assisted Mg-thermal-reduction process on a stainless-steel plate over a period of one minute, can be employed as a promising anode material for the next generation of high-energy LIBs.</P>
