우리나라 수출입의 중요한 비중을 차지하는 동아시아 지역은 지리적, 정치적, 경제적, 사회 문화적 상호보완성으로 인해 더욱 증대될 것으로 예상된다. 최근 수출입 증대와 더불어 우리나라 항만과 대동아시아 국가간의 항만 물동량 역시 증가세를 유지하고 있다. 그러나 이들 국가의 경제 규모 및 성장율의 차이, 항만인프라 수준, 지리적 위치 등과 같은 다양한 요인으로 인해 이들 항만과의 물동량은 변동성을 보이고 있다. 항만 물동량의 변동성과 항만 네트워크의 변화에 대한 많은 연구에도 불구하고 우리나라 항만과 동아시아 항만과의 보다 세밀한 연구는 제한적이기 때문에 본 연구가 이러한 갭을 보충하고자 한다. 본 연구는 우리나라의 대동아시아 지역항만간 수출 컨테이너 화물의 유통경로의 추이를 분석하고, 이를 통해 우리나라 무역업체, 선사, 물류업체, 항만당국의 정책적 실무적 시사점을 제시하는데 목적이 있다. 2007~2015년간 우리나라의 주요항만과 대동아시아 개별항만간의 물동량의 변동성을 변이할당기법을 사용하여 분석을 진행한다. 분석결과 우리나라 항만 전체적으로 Shanghai, Ningbo, Ho Chi Minh, Haiphong 등이 규모와 물동량 증가면에서 가장 중요한 항으로 나타났다. 항만단위로 볼 때 부산항에서는 중국항의 경우 Yantai, Weihai, Hakata, Kobe, Ho Chi Minh, Haiphong, 인천항은 Lianyungang, Tianjin, Osaka, Kobe, Ho Chi Minh, Haiphong, 광양항은 Tianjinxingang, Weihai, Yokohama, Ho Chi Mihn, Tanjong, 울산항은 Yantai, Lianyungang, Nagoya, Kobe, Ho Chi Minh, Portkelang항과의 항만네트워크가 중요한 것으로 나타났다. 따라서 우리나라의 정부, 항만당국, 해운 물류업체들은 이들 항만과의 물류네트워크 협력을 강화하는 한편 이들 항만에 대한 투자를 적극적으로 추진해 나갈 필요가 있다.

Vietnam is entering an important phase of urbanization that corresponds to the current economic development. Developing logistics of Vietnam in general, and Haiphong particularly, is urgent in order to meet the need for the economic development of Viet Nam in this period of international integration. Hai Phong's development record over the past 20 years is remarkable. In conjunction with the local government's efforts, external factors, such as increasing direct foreign investment, is turning Hai Phong into Vietnam's logistics hub. However, even though Hai Phong accounted for 98% of North Vietnam's throughput, its logistics services are low level, the ports are fragmented, and the port management scale is backward, with the legal system overlapping. This paper has systematically evaluated the development of Haiphong city during recent years, then offers some solutions to develop logistics for Hai Phong ports.

Objectives: This study was conducted to characterize the symptoms, mental health, quality of life (QoL), and associated factors following the coronavirus disease 2019 (COVID-19) infection. Methods: This cross-sectional study included 394 participants previously infected with COVID-19 in Ho Chi Minh City, Vietnam. Mental health was assessed using the 21-item Depression, Anxiety, and Stress Scale (DASS-21). Participants self-reported health-related QoL was measured with the EuroQol 5-Dimension 5-Level (EQ-5D-5L) scale. Results: Among the participants, 76.4% reported experiencing at least one symptom following COVID-19 infection. The most common symptoms were fatigue (42.1%), cognitive dysfunction (42.9%), and hair loss (27.9%). According to the DASS-21 results, the proportions of depression, anxiety, and stress were 28.7%, 26.4%, and 20.6%, respectively. The mean scores on the EQ-5D-5L and the EuroQol Visual Analog Scale were 0.94±0.11 and 84.20±13.11, respectively. Regarding QoL issues, the highest proportion of participants (32.7%) reported experiencing anxiety or depression, followed by pain or discomfort (25.4%). Multivariable logistic regression analysis revealed that factors associated with the presence of symptoms following COVID-19 infection included female (odds ratio [OR], 2.84; 95% confidence interval [CI], 1.65 to 4.91) and having QoL issues (OR, 3.25; 95% CI, 1.71 to 6.19). Conclusions: The study investigated the prevalence rates of various symptoms following COVID-19 infection. These findings underscore the need to prioritize comprehensive care for individuals recovering from COVID-19 and to implement strategies to mitigate the long-term impact of the disease on mental health and QoL.

The objectives of this study were to examine the association between dietary factors and underweight and overweight adult Vietnamese living in the rural areas of Vietnam. A cross-sectional study of 497 Vietnamese aged 19 to 60 years (204 males, 293 females) was conducted in rural areas of Haiphong, Vietnam. The subjects were classified as underweight, normal weight, and overweight based on BMI. General characteristics, anthropometric parameters, blood profiles, and eating habits were obtained and dietary intake was assessed using 24-hour recalls for 2 consecutive days. A high prevalence of both underweight (BMI < 18.5 kg/$m^2$) and overweight (BMI ${\geq}$ 23 kg/$m^2$) individuals was observed (14.2% and 21.6% for males and 18.9% and 20.6% for females, respectively). For both genders, the overweight group were older than the under- and normal weight groups (P = 0.0118 for males and P = 0.0002 for females). In female subjects, the overweight group consumed significantly less cereals (P=0.0033), energy (P = 0.0046), protein (P = 0.0222), and carbohydrate (P = 0.0017) and more fruits (P = 0.0026) than the underweight group; however, no such differences existed in males. The overweight subjects overate more frequently (P = 0.0295) and consumed fish (P=0.0096) and fruits (P=0.0083) more often. The prevalence of both underweight and overweight individuals pose serious public health problems in the rural areas of Vietnamese and the overweight group was related to overeating and high fish and fruit consumption. These findings may provide basic data for policymakers and dieticians in order to develop future nutrition and health programs for rural populations in Vietnam.

Sea-ports in Northern Vietnam have experienced a rapid growth of container throughput in recent years. To accompany with such development, huge investment also has been performed to enhance not only local port capacity but also the regional logistics system. Container terminals in Northern Vietnam locate centrally along Cam river of Haiphong city, leaving 2 others in Quang Ninh province. Five out of totally 11 container terminals in the area are under the control of Vinalines - a national corporation in field of maritime industry. In this paper, those terminals are classified in terms of location and ownership. The volume of container throughput and facilities of all container terminals in Northern Vietnam from 2005 to 2014 are recorded in order to compare the performance of groups. A Data Envelopment Analysis (DEA) is then applied to evaluate the relative efficiency of such terminals. Before conclusion, number of suggestions will be contributed to related parties.

Port in Northern Vietnam has been playing an important role in the logistics system the country. In recent years, the cargo throughput of the region, especially, containerized cargo has increased gradually. There are totally 11 container terminals in Northern Vietnam, concentrating in Haiphong city and Quang Ninh province. Despite of increasing demand, the competition among the terminals is becoming more and more critical. The paper, firstly, summarizes factors impacting the market share of the terminals before reveal the correlation between given factors and annual container throughput. Factor analysis will be then applied to evaluate the level of terminals' logistics infrastructure. For the conclusion, strategic thinking of terminals' logistics competitiveness will be contributed to related organizations.

We prove the existence of uniform attractors $\mathcal{A}_{\varepsilon}$ in the space $H^1(\mathbb{R}^N){\cap}L^p(\mathbb{R}^N)$ for the following non-autonomous nonclassical diffusion equations on $\mathbb{R}^N$, $$u_t-{\varepsilon}{\Delta}u_t-{\Delta}u+f(x,u)+{\lambda}u=g(x,t),\;{\varepsilon}{\in}(0,1]$$. The upper semicontinuity of the uniform attractors $\{\mathcal{A}_{\varepsilon}\}_{{\varepsilon}{\in}[0,1]}$ at ${\varepsilon}=0$ is also studied.

2014년 내지 2015년 베트남 Hanoi(분리주 VNUA3), Thainguyen(분리주 VNUA8), Haiphong(분리주 VNUA11) 지역의 닭에서 닭전염성기관지염바이러스(IBV)가 분리되었다. 이들 3주의 바이러스가 분리된 개체들은 닭전염성기관지염 생독 백신(49/1 또는 Ma5 스트레인)을 접종했음에도 불구하고, 닭전염성기관지염의 임상증상 또는 병변을 보였다. 유전자 염기서열 분석결과, IBV베트남 분리주 VNUA3, VNUA8, VNUA11은 S단백질의 분절부위에 각각 RRTGR, HRRRR, and HRRKR의 아미노산 서열을 가지고 있었다. S 유전자 염기서열을 사용하여 바탕으로 BLASTN 검색결과, 분리주 VNUA3, VNUA8, VNUA11은 각각 CK/Italy/I2022/13, CK/CH/LHLJ/08-6, GX-NN120084 스트레인과 가장 높은 유전자 염기서열 상동성을 보였다. S 유전자 염기서열을 사용하여 계통분석을 실시한 결과, VNUA3, VNUA8, and VNUA11은 각각 Q1-like, QX-like, TC07-2-like 유전형 그룹으로 분류되었다. 베트남 IBV 분리주 3종은 모두 중국에서 유행하는 IBV와 유전적 상관성이 높았으나, 베트남에서 사용 중인 IBV 생독 백신 스트레인(4/91, Ma5)과는 다른 유전형 그룹으로 분류되었다. 우리의 연구결과를 종합해 볼 때, 비록 제한된 가금 사례에서 조사되어 베트남에서 IBV 분자역학적 상황을 알 수는 없지만, 최소한 3개 이상의 IBV 유전형이 베트남 북부지역에서 존재하고 있으며, 분리된 바이러스는 중국에서 유행하는 IBV와 유전적으로 유사하였다. 이 연구결과는 베트남에서 유행하는 IBV 분자역학에 관한 최초 보고이다.
