Port operational efficiency is considered as one of the most important competitive factors and plays a critical role in the port development all over the world, especially container ports. Haiphong Port, which is in the northern of Vietnam, is planned to become one of the national and regional ports. To do this objective, it is important to analyse the operational efficiency of its container terminals. The paper aims to comparatively analyse the operational efficiency of 16 container terminals in Haiphong Port from 2016 to 2022 by basic and Malmquist DEA models. With 112 observations collected and calculated in R software, DEA models have five inputs (container yard area, number of quay crane, berth draft, berth length, labour force) and one output (annual cargo throughput). Consequently, Hai An, Tan Vu, and Vip Greenport are more efficient terminals over the 7-year period, whereas Transvina and MIPEC have lower efficiency. Paper contributions are the literature review about port operational efficiency and references to propose resolutions in next author’s research as well as masterplans to develop Vietnam seaport’s system. Besides, the limitations are discussed as the number of observations and environmental factors in ports.

오르막차로는 오르막 구간에서 속도 감소가 큰 대형차의 혼입률이 증가하여 교통용량의 감소가 크게 예상되는 경우, 고속 교통류에서 저속 교통류를 분리하기 위해서 설치된다. 오르막차로와 관련된 기존의 연구는 오르막차로의 구간선정, 시종점 위치, 설치방법 등 주로 도로설계기준과 관련된 내용에 집중되어 왔다. 그러나, 교통운영측면에서 오르막차로는 교통량이 증가할 경우 주요한 병목지점이 된다고 알려져 있는 바, 본 연구에서는 교통운영측면에서 교통량(v/c), 중차량비, 종단경사에 따라 오르막차로 일시 폐쇄가 혼잡 감소에 미치는 영향을 파악하고 아울러 적절한 교통운영기준을 수립하고자 하였다. 중부내륙고속도로 낙동분기점 부근의 오르막구간(136.9K~133.3K, 길이 3.6km, 구배 3.7%)을 대상구간으로 선정하여 교통운영변수에 따른 시뮬레이션 분석을 수행한 결과, 교통량과 중차량비가 오르막차로의 주요한 교통운영기준이 되는 것으로 나타났다. 즉, 오르막차로로 인한 혼잡을 막기 위해서는 교통량비가 0.8이고 중차량비 50%일 때 종단경사와 상관없이 폐쇄하는 것이 효과적이며, 교통량비 1.0일 경우에는 중차량비, 종단경사와 상관없이 오르막차로 폐쇄가 효과적으로 나타났다. 특히 일반적인 소통상황에서는 오르막차로 운영효과가 더 큰 것으로 나타나, 교통량 및 중차량비의 변화에 따라 오르막차로의 탄력적 운영이 필요함을 알 수 있었다. 본 연구를 계기로 도로시설의 탄력적 운영기준에 대한 연구가 활성화될 수 있을 것으로 기대된다.

This study examines the relation between the quality of leader-member relationship and operational performance of processing enterprises employees in Vietnam, while job satisfaction and innovation are as a mediator variable. In depth interviews are first conducted with five managers and professional workers in five processing enterprises to determine the latent variables and build the structured questionnaire with observed variables. A quantitative survey with 438 employees and managers from 300 processing enterprises was carried out. The method of exploratory factor analysis (EFA), Cronbach’s alpha analysis, and confirmatory factor analysis (CFA) was used to test the reliability, the convergent nature, and the consistency of the concepts. Structural equation modeling (SEM) is used to test the proposed model. The result shows that job satisfaction, innovation and operational performance have positive effects on the quality of leader-member relationship. The relationship between leaders and members had indirect impact on employee’s operational performance via their job satisfaction and innovation, which illustrates a mediator role of job satisfaction and innovation for employees’ performance. The findings of this study suggest that managers need to focus on developing relationship with employees to improve their satisfaction, innovation and performance.

The comprehensive rural village development projects (CRVDP) have been carried out as the core one of the rural development schemes in Korea since 2004. CRVDP included the various rural experience programs to increase rural income and in order to promote rural community development in the project area. This study analyzed the operating management conditions, types and characteristics of the rural experience programs targeting the 168 CRVDPs have been completed so that the recommendations and lessons which were found the usefulness, challenges and improvements to the CRVDP can be provided to be better the same kinds of rural development projects. We identified the relationships between performances such as increasing village income and utilization of rural amenity resources to the CRVDP and operational management types of the rural experience programs as well. Employing principle component analysis and cluster analysis technique, this study found 5 clusters of rural experience programs among 168 CRVDPs. The results of analysis of variance indicated that there were significant the mean differences between clusters such as the utilization of rural amenity resources(0.01), income of rural experience programs(0.1). According to the result of the Chi-squire test, there was very significant differences between internet homepage operation and clusters(0.01). Finally, the analysis of covariance about the income of rural experience programs showed that there were significant the mean differences between clusters(0.05).

The purpose of this research was to investigate and analyse how Community Forest Initiatives as urban fringe management initiatives made alliances with a variety of interest groups, enrol them in the urban fringe management processes using the Actor Network Theory. The Thames Chase Community Forest Initiative was selected and its area of operation included a 97 km2 area of green-belt area in East London. It was a instrument far improving and protecting the unique characteristics of the countryside landscape from urban developments as well as evaluating the impact of forestry inclusion in land use planning in the urban fringe. It was operated through a tiered structure comprising the Thames Chase Joint Committee and the management team. They employed a variety of devices to speak with one voice to bring about an effective operation process and to secure the enrolment of a variety of interest groups in its operational processes. Of note, the initiative's actor network impacted on improvement to and management of the countryside landscape despite not owning any land itself. As a result, when urban fringe management initiatives will be launched in South Korea to achieve a more effective and efficient urban fringe management, local councillors and representatives from public and non-government bodies should be more responsive to local communities' views and needs and work more vigorously on their behalf through lobbying, seeking media support, and so on. Moreover, better understanding and communication between local authorities' officers and management initiatives' teams are essential to avoid duplication of work practice.
