Of all the site logistics technologies in high-rise building construction, both vertical and horizontal move plan, are the most imperative factors. And the horizontal plan follows lift-up plan as of the vertical plan. However though it may be, temporary lifts on site are numbered by heuristic formulas. The quantity of finishing material cannot be converted into lift-up load per finishing material. The lift-up plan cannot be evaluated the feasibility for finishing material move plan by a reasonable evaluation methodology. The horizontal plan is far from the vertical one. And the information as an input data for the horizontal plan is devoid of package unit size, length, and volume per finishing material. These can hardly result in reasonable and detail decision on how much to use temporary lifts, how long to use these, and where to deposit each finishing material. Therefore, this study is to suggest a decision-making model that can integrate vertical and horizontal material move plan in high-rise building construction and make a decision the plans systematically. And the study is to explain the concept, methodology, and contents of the model applied to a virtual project, named as MT 130 (Millennium Tower 130). By the model, the planner can shift his/her thinking framework on site logistics management products-oriented Into process-oriented. He/she can manage a project by the framework as system thinking, evaluate the feasibility of a lift-up plan, and decide the horizontal plan integrated with the lift-up.

The opening of High-speed Rail provides convenience to move a long distance quickly, and the passengers of high-speed railway have been steadily increasing each year. Since the high-speed rail is far more expensive than other transportation, providing high quality service over just the high speed is required. Accordingly, much effort is made to improve service quality. However these services have been focused on general passengers so we should introduce a new service system to meet personal preferences of passengers. Therefore, in this paper, we introduce integrated railway service systems to provide service which follows the individual needs of passengers and is based on RFIDs (Radio Frequency Identification).

Railroad started from invention of stream locomotive at the beginning of the industrial revolution. Development of diesel and electric locomotives in railroad induced science and technology since the industrial revolution. Korean high-speed train so-called high-speed train project, is localized 86.7%(compared to price), 92%(compared to number of parts). This technology has been contributed to KTX since 2004. High-speed railway was developed to integrated system, which is contained high technology such as civil, mechanical and electrical technology. This effects to advanced technology across the board science, technology, industry. High-speed railway is fast, safe, comfortable, eco-friendly as next generation's representative transportation. Furthermore it is inaugurate the era of the new railroad. Korea is opened the high-speed railway following Japan, France, Germany, Spain. Korea became the fifth nation of the high-speed railway. It joins the rank of developed countries operating at the speed of 300km/h. Especially, KTX is emerging as advanced transportation with reducing logistics costs significantly due to time advantage and transportation revolution. The purpose of this study is to present the strategy through internal and external railway market's analysis for Korea railway system's globalization expansion(overseas expansion).

This research is to investigate the effect of the improvement of investment environments with investment incentive on Korean national economy by looking into the foreign investment support system in Korea. To this end, first research model was set up based on our literary study and case study was conducted on 150 foreign companies that were located in industrial complex for foreign companies, received the tax benefit and government subsidization. And it was found that even though the foreign companies were contributing to the national economy in general such as in the area of production, export, employment, development of technology, there was no significant contributory difference between the investment incentive beneficiary and non-beneficiary foreign companies. Therefore it deemed reasonable to reconsider the way Korean government supports foreign companies in Korea and to reinforce foreign companies' relevance to national policy agenda with additional incentives to foreign companies located in comparatively less developed areas. As a way to promote foreign investment, promotion of investment infra such as improvement of follow-up services, openness to foreign investment, industrial deregulations in capital area, revitalization of free economic zone, efficient system to promote foreign investment and the reinforcement of public relations were considered necessary, especially the upgrading of economic structure and the integrated management of domestic and foreign investors deemed necessary for the optimal distribution of the industries.

EPCIS(EPC Information Services) system is a core component of EPCglobal Architecture Framework offering information of the freights, the time of awareness and the location of awareness on the EPCglobal Network. The role of EPCIS is to exchange information based on EPC. There are four kinds of event data which are object event data, aggregation event data, quantity event data, and transaction event data. These EPCIS events data are stored and managed in EPCIS repository. This study suggest the quantitative modeling about total number of EPCIS event data under the assumption to aware the RFID tags of items, cases(boxes), vehicles(carriers, forklifts, auto guided vehicles, rolltainers) at a time on the reading points. We also estimate the number of created EPCIS event data by the suggested quantitative modeling under scenario of process in the integrated logistics center based on RFID system And this study compare the TO-BE model with the AS-IS model about the total sizes of created EPCIS event data using the simulation, in which we suggested the TO-BE model as the development of the repository by skipping the overlapped records.

With the recent port environment, the integration of the separated berth is being actively progressed and the necessity of integration has been strengthening. Therefore, the application of existing gates have to review in order to reduce the truck turnaround time and to distribute the truck traffic volume in port container terminal. This paper analyzed the operation impact both the integrated gate and the separated gates. As the result of the analysis, this study suggests the separated gate system as an efficient design for gate operation considering integration of two individual berth.

The Korean government is developing a systematic plan of integrated coastal management for effective conservation, utilization, and development of coastal areas. For this plan, integrated maps of land maps and nautical charts are indispensable. However, these maps are not made, nor studied yet in terms of integration, although digital maps(DM) on land and electronic nautical charts(ENC) have been recently developed by Korean Geography Institute and National Marine Investigation Institute, respectively. In this study, as preliminary studies to make eventual integrated maps, the concept of coastal areas are defined, specifically, coastal lines from DM and ENC are matched against each other. Issues on map production procedures, coordinate systems, and map projections, are carefully considered. A test coastal area located in Seo-Gu, Pusan, over 14 km of coastal lines is selected for the edge matching of coastal lines. RMS differences are 13.83 m and 4.37 m over man-made coastal lines and natural coast lines, respectively, which are quite larger considering a scale difference and other factors. However, no systematic differences are found.

This study has done to search for a solution to remove risk limitedly caused by separating weapon system acquisition from operation and maintenance at the view point of Logistic Commander who's responsible for stable operation and maintenance after acquiring weapon system. At the System development stage, unverified overhaul development plan may cause additional manpower and costs after the development, and furthermore it is likely to have risk to lower reliability of the military. Thus, research and development agency should write overhaul development plan at the System development stage, and it should be verified through evaluation and verification test. Secondly, during research and development, institutional supplementation is needed to calculate human and material resources writing overhaul development plan. Thirdly, it should be able to analyze proper operation & maintenance plan and cost for overhaul plan at the pre-investigation stage. Fourthly, the base which can develop overhaul concept and overhaul factors should be included in the need and need determination document. Lastly, for the weapon system which has small amount of high power figure, project management should be performed to be able to specify at the each acquisition level of weapon system to realize Article 28, clause 3 and 4 of Defense business law.

We have to prepare for the existing threats from North Korea and potential threats in the future. It is important to utilize our resources as effectively as possible to build military power that brings victory in a war. Based on a sustainable required operational capability, weapons systems at the acquisition stage need to maintain a combat-readiness posture and ensure operational sustainability. To achieve this, establishment of procedures that develop elements of depot maintenance at the beginning, which enables economical and effective depot maintenance during that stage, is essential. First, the requirement paper needs to develop the concept of the depot maintenance requirement through the pre-study outlined by this paper. Second, at the system development stage, a Development Plan of Depot Maintenance draft should be proposed. This is the initial paper that can develop the elements of depot maintenance, and it should be verified by a field test. Third, each force's logistics command should write a Depot Maintenance Direction draft and a Mid-term Requirement of Elements of Depot Maintenance draft with the proven Development Plan of Depot Maintenance draft. Also, the verified paper needs to be realized and renewed by the time the Requirement of Elements of Depot Maintenance draft is completed. In conclusion, the procedures explained above will contribute to build an economical and effective military power in a reality faced with a resource shortage and threats from the enemy.
