CUPPS is the latest international standard passenger processing system which is operated with airlines' check-in system, DCS (Departure Control System) in order to provide check-in and boarding services to passengers. The CUPPS standard has been revised in August 2009 leading by IATA (International Air Transport Association) who recommends replacing old legacy common use system with CUPPS to airports and airlines around the world. IATA is expecting to reduce the installation and maintenance cost of CUPPS by standardizing various legacy common use systems and device controls. Airlines are also expecting to take advantage of the system to reduce the application development cost as developing only one standard CUPPS application instead of developing multiple applications for nonstandard legacy systems. This research which focuses on development completed AIRCUS, R&D project of ministry of land, transport and maritime affairs accomplished by IIA, will present the result of pilot trial and the effective approach methods to increase the possibility of expanding overseas business by comparing old legacy system with CUPPS to prove the dominance of CUPPS over the legacy systems as well as doing foreign case studies.

Recently, It became possible to transport freights and energy resources via Northern Sea Route(NSR) as global warming has been accelerated. As a result, all countries of the world and Korean local governments have had a struggle to take the advantageous position first in NSR development. However, this extreme competitions might have a negative effect on the national port industry and cause unnecessary social costs and economic losses. Therefore, the main target of this study is to find the most suitable port for NSR using AHP analysis. Most of the data was gained from previous literatures and public statistics and the weight of each factor was calculated by the result of expert survey. As a result, Busan port has the biggest competitiveness, followed by Yeosu Gwangyang, Ulsan and Incheon. From the result, this study suggested 3 possible scenarios. The first scenario specializing Busan port in NSR focuses more on developing the related businesses such as repair of ships, refueling, ship stores trade than attracting the more cargoes. the second is a strategy to make Ulsan port as a hub for energy resources, especially liquid cargo on NSR. the last is a mixed one to assign suitable roles to the ports according to their competitive capabilities.

This paper attempts to evaluate the local economy and the local economic development policy in Goryeong County and to propose some policy alternatives for local economic development. Goryeong County has a locational advantage, which is not just geographically proximate to Daegu, a large metropolis, but also connected directly to the national highway networks. This region can also be regarded as a rural area, in a sense that the primary industry still plays a more important role for the local economy than the secondary industry and the tertiary industry. However, it is problematic that the local economic development strategies of Goryeong are universal rather than strategic and systematic. In order to design an effective regional economic development policy, the policy makers are necessary to deliberately consider regional specificity and geo-political and geo-economic situations around the region. In addition, it is important to say that policy makers, particularly in rural regions, need to break from the fantasy of high-tech industries. In this context, I propose some region-specific and context-specific policy ideas, including the promotion of the agro-food cluster and the build-up of the em-industrial complexes specialized in mechatronics and transportation equipment manufacturing.

The modular construction has several advantages such as high quality of product, safe work condition and short construction duration. The manufacturing planning of modular construction should consider time frame of manufacturing, transport and erection process with limited resources (e.g., modular units, transporter and workers). The manufacturing planning of multi modular construction project manages the modular construction's characteristics and diversity of projects, as a type of modular unit, modular unit quantities, and date for delivery. However, current modular manufacturing planning techniques are weak in dealing with resource interactions and each project requirement in multi modular construction project environments. Inefficient allocation of resources during multi modular construction project may cause delays and cost overruns to construction operation. In this circumstance, this research suggest a manufacturing planning model for schedule optimization of multi project of modular construction, using genetic algorithm as one of the powerful method for schedule optimization with multiple constrained resources. Comparing to the result of the existed schedule of case study, setting optimized scheduling for multi project decrease the total factory producing schedule. By using proposed optimization tool, efficient allocation of resource and saving project time is expected.

In present, physical distribution industry fields are offering more convenient services using RFID, but there is plenty of room for improvement. And then, utilizing advantages of RFID which quick and simple manages goods and GPS which gets information of position at the present, we implemented a physical distribution management system can manages the information for distribution process of goods easier. We can get much information that the number of loaded goods, the data of goods, the state of distribution, whether or not missing, etc. as attached a RFID reader to the truck. and when truck is moving, we can also obtain much information consumer want that the real time data of position, distribution routes, etc. for loaded goods as received a latitude and longitude from GPS. These information have recorded, managed, and linked Google map, we can grasp the distribution information of goods on World Wide Web service. Because this service is focus on the image not the text can give the information required by the consumer on visual, it is different from the existing service. At this point of time that the RFID and GPS have used in overall industry, If these services have researched and developed with transportation, tour, etc. industry as well as physical distribution, it is possible to utilize more widely.

In Korea, more than 70% of the ammonia(NH₃) released into the atmosphere is known to originate from livestock manure. The total emission (kg year^-1) is calculated by multiplying the emission factor (kg head^-1 yr^-1) and the activity data (head). To improve the accuracy and reliability of the NH₃ emission estimation process, an accurate account of livestock manure production, calculation of NH₃ conversion and generation during the composting and liquefaction of manure, estimation of NH₃ generation in the storage and transportation of manure and compost, and a comparative study of NH₃ emission during the soil spreading process must be performed. Compared to the US and EU-28, in particular, the domestic emission factor is relatively even and the spatial/temporal scale is not broken down sufficiently to reflect the domestic situation. As a way to improve the accuracy and expertise of estimating NH₃ emission factors, a 'dynamic chamber-capture system' can be utilized, which allows complex considerations of compost, liquid manure, soil, and climate characteristics. By reviewing and comparing the data related to domestic and foreign NH₃ emission, we identified shortcomings in the current domestic system and the directions to be taken and suggested a chamber system that could estimate NH₃ emission flux. It is also necessary to establish a methodology for mesocosm systems in the field, in addition to indoor chamber systems, to be linked with practical policies, such as the calculation of new emission factors for missing sources.

As computer systems of high capacity and high performance recently emerged, various researches about GISs(Geographic Information Systems) have been in progress and many GIS applications have also been developed. From the domestic situation where many people are using mobile devices, because of the recent advances in the mobile technology, we can infer that the time will come when every individual will carry a mobile device with a GPS(Global Positioning System) module resulting from the development of a miniature GPS Module. Therefore, a mobile GIS that can allows users to deal with dynamic GIS data management and perform their tasks while moving will be required. This paper discusses the design and implementation of a mobile GIS using the shareware DBMS, called postgresSQL. The Mobile GIS in which a mobile concept is utilized at the GIS data server makes it possible to insert, delete, update GIS data, to zoom in and zoom out displayed maps, and to locate the user's position on the client device. Therefore, It is possible to manage dynamic GIS data in order to deal with GIS data on the maps while moving, connect various GIS data servers through the middleware, and connected with ITS (Intelligent Transport System) which is one of applications of the Mobile GIS developed in this paper.

Korea's trade balance in service showed surplus in 2012 on the basis of BPM5. This is recorded by 14 years since 1999. This owes to decrease of deficit in tourism balance, increase of surplus in construction and transportation, and shift from deficit to surplus, even in small portion, in personal cultural recreational services balance. While externally the global economic growth becomes inactive and the Korean Won has appreciated, internally Korean service industry is very weak and is not equipped with international competitiveness. This study intends to look into service surplus items and services deficit items and to present measures that will be able to strengthen competitiveness in service industry. As a short case study, German and Japan was benchmarked, as they are the countries which are developed on the basis of manufacturing like Korea. And in this study, by analyzing surplus items and deficit items in trade balance sheet, it is attempted to suggest policies which would be available for strengthening service industry. As the service industry is a highly value-added one, it is necessary to designate promising categories and intensively foster as strategic industry. Service industry has their own characteristics distinguished with manufacturing goods. It has very different logistics and payment system with manufacturing industry. It means there must be independent support systems which reflect the nature of industrial classification in service industry. It is necessary to provide export support system, to organize export market development group, to support marketing, to set common logistics center, to support diplomatic means, to provide legal service and so on.

This study examined elements which could evaluate a container terminal logistics system from the viewpoint of supply chain management. This study derived the elements of a container terminal logistics system such as flexibility, reliability, responsiveness, and information sharing and 16 evaluation sub-items in the aspect of a supply chain. In the result of analysis, the weight between SCM elements of a container terminal logistics system was the highest in reliability(0.282), followed by flexibility(0.273), responsiveness(0.224), and information sharing(0.221). The conversion weight was calculated by combining the weight of elements of a container terminal logistics system and the weight of evaluation sub-items. The highest weight which was considered as the most important factor to evaluate a container terminal logistics system was work planning(berth, yard) of flexibility(0.081), followed by accurate fulfillment of container work schedule(ship, yard) and the optimum distribution and arrangement of equipment(QC, TC, YT)(0.079), stable works without damage of containers and ships(0.071), and preventive maintenance of equipment and operators' skill(0.070).
