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.

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.

Meiobenthos Assemblages in the Mekong Estuarine System with Special Focus on Free-living Marine Nematodes

Ngo Xuan Quang,Ann Vanreusel,Nic Smol,Nguyen Ngoc Chau 한국해양과학기술원 2010 Ocean science journal Vol.45 No.4

Meiobenthos assemblages in eight estuaries of the Mekong river system were investigated in August 2008 (from the Cua Tieu estuary to the Tran De estuary). In each estuary, one sampling station was established for meiobenthos sampling. Twelve major taxa of meiobenthos were recorded in this estuarine system, including Nematoda, Copepoda, Turbellaria, Polychaeta, Oligochaeta, Tardigrada, Bivalvia, Ostracoda, Amphipoda,Cumacea, Gastrotricha, Gastropoda, and Crustacean Nauplii larvae. The densities of the meiobenthos range from 581 to 3168 inds/10 cm2. Nematodes always occupy the highest numbers with a percentage ranging from 64-99%. There are 135 nematode genera recorded in this study with the following as dominant genera Desmodora, Leptolaimus, Halalaimus, Thalassomonhystera,Theristus, Daptonema, Rhynchonema, Parodontophora, and Oncholaimus. Although the biodiversity of the meiobenthos at higher taxa level is not high compared to other marine environments, the estimates of nematode biodiversity at the genus level indicates high values. The increase in number of genera with increasing sampling intensity illustrate that the diversity is underestimated and would have been higher if the authors had considered a larger number of individuals, more replicates per station, and more sampling stations.

Promoting Civic Participation in Vietnam: the Case of the New Rural Program in a District of Ho Chi Minh City

Ngo Hoai Son,김판석 한국외국어대학교 동남아연구소 2016 東南亞硏究 Vol.25 No.3

The government of Vietnam has implemented “the National Target Program on New Rural Development” for the period 2010–2020. The New Rural Development Program was launched in 2008 focusing on development of rural areas in several dimensions (i.e. rural planning; infrastructure development, economic structure transition, economic development, and income increase, etc.). The key to the success of this program falls on not only the political will, but also the civic participation, in the local area. Although local citizens in rural areas have growing expectations for the development of their area, they have not been historically active under the socio-political culture in Vietnam. Local residents participating in the local development programs engage in discussions with local authorities about program implementation. However, there appears to be a low level of participation in every arena of participation. Accordingly, this paper argues that people in rural areas do not have sufficient opportunity to interact efficiently with local government for a better policy implementation. A developed local infrastructure needs to be improved to ensure a long-term and sustainable growth to meet requirements of industrialization and modernization in line with the national and regional development plans. Moreover, the politico-administrative competences and quality of officials at the grass roots level should also be strengthened. Furthermore, the openness of government to public discussion and involvement is another factor that allows successful civic participation.

MIMO-OFDM에서 PAPR 저감 및 사전 왜곡기에 의한 HPA의 전력 효율 개선

NGO THI THU TRANG,한태영,김남 한국콘텐츠학회 2005 한국콘텐츠학회논문지 Vol.5 No.1

In this paper, we evaluate the peak-to-average power ratio (PAPR) performance in a space-time block code (STBC) multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) system using selected mapping (SLM) and partial transmit sequences (PTS) approaches. SLM and PTS methods are used to decrease the nonlinear distortion and to improve the power efficiency of the nonlinear high power amplifier(HPA) in the MIMO-OFDM system. In simulation result, when compared with the existing MIMO-OFDM system using QPSK, the PTS method reduces the PAPR about 5 dB while the SLM method can reduce about 3.5 dB. Also, we find the BER performance of the MIMO-OFDM system with and without the predistorter in front of the HPA. When the predistorter is used, the input back-off (IBO) of 4 dB is required in the PTS method, and IBO of 6 dB in the SLM method to closely conform to the linear amplifier. If the method of improving the PAPR is not used, the value of IBO of 8 dB is required. 본 논문에서는 SLM(selective mapping)과 PTS(partial transmit sequence) 방식을 이용한 STBC MIMO-OFDM(space-time block code multi-input multi-output orthorgonal frequency division multiplexing) 시스템의 PAPR(peak-to-average power ratio) 성능을 분석한다. MIMO-OFDM 시스템에서 SLM과 PTS 방식은 비선형왜곡을 줄이고 비선형 HPA(high power amplifier)의 전력효율을 개선하기위해 사용된다. 시뮬레이션 결과에서는 QPSK를 사용한 기존의 MIMO-OFDM 시스템과 비교하였을때, SLM의 PAPR이 3.5dB 정도 줄어드는 동안 PTS는 5dB 정도 감소되는 결과를 볼 수 있다. 또한, HPA의 앞단에 사전왜곡기의 유무에 따른 MIMO-OFDM 시스템의 BER 성능을 분석해 본 결과 사전 왜곡기를 사용하였을 때 선형 증폭기에 근접하기 위해서 SLM 방식에서 6dB IBO(input backoff)가 요구되고 PTS 방식에서는 4dB가 요구됨을 확인하였다. PAPR을 개선하는 방식을 사용하지 않으면 8dB의 IBO가 필요하다.

Isolation and Identification of the Antibacterial Metabolite from Aspergillus sp. KRICT-MF24 against Erwinia amylovora

Ngo Thi Men,Jae Woo Han,Ji Hye Choi,Yong Ho Choi,Myoung Soo Park,Hun Kim,Gyung Ja Choi 한국농약과학회 2021 한국농약과학회 학술발표대회 논문집 Vol.2021 No.11

The plant pathogenic bacterium, Erwinia amylovora, causes the devastating disease known as fire blight in Rosaceous plants like apple, pear, quince, raspberry and several ornamentals. The culture filtrate of Aspergillus sp. KRICT-MF24 isolated from marine environment has potential to inhibit the growth of E. amylovora. To isolate and identify the antibacterial compound, the culture filtrates were successively partitioned with ethyl acetate and n-butanol. Through in vitro activity-guided fractionation of ethyl acetate layer, we isolated a pure antibacterial compound. The chemical structure was identified as asperlin by MS and NMR spectral analyses. The inhibitory effect of asperlin on the growth of E. amylovora and other plant pathogenic bacteria was investigated using broth microdilution and agar dilution methods. Asperlin showed the inhibitory activity against E. amylovora and Clavibacter michiganensis subsp. michiganensis with minimum inhibitory concentrations of 250 and 125 μg/ml, respectively. Our results suggested the Aspergillus sp. KRICT-MF24 and asperlin could be useful for the development of new antibacterial agents to control E. amylovora.
