한국은 1940년대 남북분단 이후 국제 무역 및 물류를 위해 해상운송에 의존해 왔으며, 현재는 북한을 경유하는 유라시아 횡단 물류를 위해 새로운 경로의 개발을 준비하고 있다. 이를 위해 극복해야 할 많은 어려움이 존재하지만, 한국은 아시아와 유럽 구간의 기존 해상경로보다 짧은 새로운 육상경로가 앞으로 더욱 빠르고 비용 효과적인 물류서비스를 통해 더 많은 교역을 가져올 것으로 기대하고 있다. 이와 관련하여 본 연구는 한국종단철도가 개발되어 중국 및 시베리아 횡단철도와 연결된 상황에서의 국내물류 변화를 미리 분석해 보고자 한다. 국내 물류시스템의 모델링을 위해 시스템다이내믹스 시뮬레이션 기법을 사용하였다. 시뮬레이션 결과 수도권과 가까운 의왕 ICD의 물동량은 증가하는 반면, 부산항의 물동량은 감소할 가능성이 있는 것으로 나타났다. 철도를 활용한 유라시아 횡단 물류의 성공을 위해서는 본 연구의 보완과 더불어 국내 물동량 처리 용량의 조정에 관한 후속연구가 필요하다.

This paper is a part of the regional characteristics of Korean chotkal. The kinds and materials of Korean chotkals are studied by interviewing local people living in 142 different regions which are bigger than 'myon' in size. Regions are classified according to the structural style of commoner's house. Regional characteristics of chotkal are analyzed and interpreted with natural environmental factor. The rest of my further interested subject will be followed in later issues ; the ways of preservation, period of fermentation according to the regional characteristics and uses of Korean chotkal. The results of this study can be summerized as follows, 1. There are 145 different kinds. 2. Raw materials of 145 kinds of chotkal are devided roughly into five groups ; (1) fishes in 87 kinds (2) Pelecypoda and Gastropoda in 14 kinds (3) Cephalopoda in 10 Kinds (4) Crustacea in 32 kinds and (5) Holothuroidea and Echinoidea in 2 kinds. They can also be classified according to the parts of individual material ; (1) body or flesh in 118 kinds (2) internal organs in 15 kinds and (3) eggs in 12 kinds. Regions are devided into four provinces ; 'Kwanso', 'Chungbu', 'Nambu', and 'Kwanbuk' in which the number of different kinds of chotkal are 32, 41, 99 and 34, respectively. Raw materials vary because of the distribution of marine life in different regions. Fishes and Cephalopoda are used in all four regions, Pelecypoda and Gastropoda in 'Kwanso', 'Chungbu' and western part of 'Nambu' regions. Different species of Crustacea used in each different regions ; sea crab and sea shrimp in the western coastal area, fresh water crab in the field area, fresh water shrimp in 'Chollado', mantis crab at 'Shihung-gun' in 'Kyonggi-do', Holothuroidea and Echinoidea are used in 'Nambu' regions. Chotkal are not used at all in six local districts which are located in inland areas where the transportation is inconvenient.

Despite the importance and necessity, the 3PL has not been activated to date. Among many views, customers claim that logistics service provider(LSP) are not prepared or capable of offering satisfactory 3PL services, while LSP emphasize the lack of mutual trust, closed corporate culture of the customer and excessive demand for reducing the costs. With this keeping in mind, it surveyed difference of perception between users and providers of 3PL services in terms of the actual status of using 3PL services, the degree of satisfaction and key factors for selecting 3PL provider through the questionnaire. As shown in this study, 43.3％ of the respondents outsourced logistics services. However, Most company outsourced only inland transportation (49.5％) which is a simple and limited scope of 3PL services, but it also indicated that the percentage of users have ranged was less then 10% in outsourcing their whole logistics sector to 3PL provider and employing other logistics functions. Among respondents, a majority of the service provider stated that they offered satisfactory cost-saving to the customers, while users felt that the degree of satisfaction for using 3PL services was evaluated as at an average level and they more highly regarded the strong partnership of their 3PL provider rather than the saving of cost and improvement of customer's services. Moreover, in contrast to the 3PL providers which regard the most important factor for selecting 3PL service provider is the logistics cost quoted, users of 3PL services felt that the quality of services was more significant than the reduction of cost, and this tendency for selecting 3PL providers was shown in more advanced countries. While users of 3PL services indicated that the main reason for not using 3PL services was to avoid disclosing information of their business and it costs much for employing 3PL providers than doing themselves, 3PL providers thought it was due to reluctancy of opening information and resistance from the logistics division engaged in logistics activities concerned. Accordingly, providers and users of 3PL services should trust each other and prepare plan to activate 3PL services under the collaborative relationships as soon as possible.

This paper considers the problem of scheduling loading and unloading operations of a crane in a railway terminal motivated from rail-road container transshipment operations at Uiwang Inland Container Depot (ICD). Unlike previous studies only considering the total handling time of containers, this paper considers a bi-criteria objective of minimizing the weighted sum of the total handling time and tenant service time. The tenant service time is an important criterion in terms of terminal tenants who are private logistics companies in charge of moving containers from/to the terminal using their trucks. In the rail-road container shipment yard, the tenant service time of a tenant can be defined by a time difference between beginning and finishing loading and unloading operations of a crane. Thus, finding a set of sequences and time of the crane operations becomes a crucial decision issue in the problem. The problem is formulated as a nonlinear program which is improved by linearizing a nonlinear constraint in the model. This paper develops a genetic algorithm to solve the problem and performs a case study on the Uiwang ICD terminal. Computational experiment results show that the genetic algorithm shows better performance than commercial optimization solvers. Operational implications in terms of tenants are drawn through sensitivity analyses.

Maritime transport is dominant in the overall volume of all international transportation. Existence and overcoming of problems, which cause pressure on shipping safety, remain actual and fully concern both maritime and inland transport. Increasing speed and cargo capacity of the ships along with the reduction of crew members lead to the automation of a growing number of work processes, which indicates the need to actively introduce appropriate measures in the security system of sea-going ships and commercial ports and to develop modern approaches to minimize negative events and incidents in the process of ship operation. Advantages in use of modern methods of monitoring the safety of ship operations, management of possible events and incidents, including investigation of accidents, first, aimed at prevention of negative occurrences and ways of prevention on this basis. Considering statistics on incidents increase, this work presents analysis of general ship accident rate, study of major accidental events growth annually, and investigation of causes of incidents, which most frequently occur in port waters and at open sea. A survey of current approaches to ensuring the safety of shipping by implementing effective tools, such as event and incident management, has been conducted.

In Korea, there has been no revegetation applicable standard for slopes formed by road construction work up to now, so revegetation work has been done using mostly foreign varieties in the manner of early revegetation. However, foreign varieties have some shortcomings; for example, they tend to be dried to death after construction work. Besides, due to the rift in the supporting soil, these revegetated varieties are often displaced from the slopes. Thus, the Ministry of Construction & Transportation on July, 2005 established revegetation standard on the slopes suited for the natural eco-system of Korea and organized positively recommending directions for using self-sewn plants growing near the slopes in overall consideration of soil, weather, regional conditions. The locations specified in this direction are the slopes at the road construction jobsite like the expressway, highways, and local roads. In addition, the Ministry's standard and directions stipulated that damaged slopes's natural environment and eco-system due to various road construction work should be restored, and thus a feeling of stability and pleasantness should be provided to road users as well. Also, the Ministry tried to select seed plants and revegetation measures suited for surrounding environment to put the environment-friendly slope revegetation measures into practice through the test revegetation work in order to prevent illegal construction practices and to improve the quality of revegetation. According to the direction, revegetation districts aimed at the slopes are divided into three ones in consideration of weather environment, regional environment, and forest environment as follows : national territory's core ecological green-land based district centering on the Taebaek Mountains; coastal ecosystem district including islands off the coast; inland eco-system district. The combination of revegetation plants according to environment revegetation districts, should be executed by dividing into herb-oriented type, woody plant colony type, and bio-species versatility restoration type, and the selection of seeding plants should be done in the presence of a supervisor and through test construction results and technology counseling from a specialist in natural eco-system restoration and revegetation measure seed combination standard according to environment revegetation districts. This direction will be executed in the manner of monitoring until the yea 2008 and 2009 it will be finalized and enforced on December, 2009.
