According to 2012 OECD environmental report, Korea was ranked as the first country of water stress. Water footprint is a method to calculate water usage during the life cycle of a product from material procurement through production to disposal to recycle and to quantify the load to water resources. In water footprint calculation, water consumption unit is used. Agricultural water use is over 48% so it is urgent to mange that area Korea needs to spread the discussion about water footprint as quickly as possible, for the study to prevent social and environmental problems due to water shortage. This paper, through water footprint calculation and comparison in Chungju and Geochang areas, looks to counter measures for water risk, targeting domestically-produced apple.

Engineering database for CIM of injection mold production has been developed to manage design information and parameters of injection mold. The database has direct connection with product data management system and management database. Design specifications are generated in initial stage of mold design with integration of management information. Design parameters and bill of materials for mold base parts are generated during the CAD process and transferred to the manufacturing database and procurement system. Standard modules for parts and mold base are constructed using national standard and legacy data of industries. The engineering database provides important information route for CIM of injection mold design and production.

The level of information system interoperability of DPMS(Defense Procurement Management System) and DCMIS(defense weapon system configuration management information system) was measured. Two information systems interoperability is analyzed using measured results and the level of interoperability were estimated. The results was directed to the future improvement project of information system.

There is a big change in Electronic Commerce. With little or no profit projected for the foreseeable future with the dotcom companies, Internet venture capitalists are looking for new business models. They are now turning to B to B Electronic Commerce. It is expected that B to B Electronic Commerce will be more active than B to C in the very near future. In the future B to B Electronic Commerce will move to include collaborative Electronic Commerce which includes product development, engineering, material procurement, and management. Even though the solution to this multidimensioal and complicated process may take some time, a total solution to this will dramatically change the landscape of Electronic Commerce. Thus the various corporations must work together to find the total solution that will build this infrastructure.

This paper focused on problems of design, construction, and maintenance caused by construction implementation processes. They were analyzed through case study of structure safety diagnosis projects. From the case study, it is expected that the introduction of Construction Management from the first stage of procurement will improve construction cost increase or burden on small design company. It strengthens coherent management from design and source contractor selection to build review of responsibility. The coherency will prevent changes in designing or infirm unreliable construction. It is desirable that expert opinions are considered when structure changes and establishment occur and that, if necessary, actions such as source selection, periodic audits, and diagnosis arc checked and fed back to maintenance.

The purpose of this study was to look up the proper inventory management system in construction industry. it is important for construction company to improve competitiveness and to reduce construction cost. Lot-sizing techniques were applied to rebar procurement in apartment project. The results of this study were as follows; the method of Groff's marginal cost showed the best performance of other techniques and the method of Norman showed a similar result.

Advanced countries have mandated applying BIM in construction projects. Also, Public Procurement Service has planned to mandate applying BIM to all construction project that ordered in PPS from 2016 in KOREA. However, now Seumter that is building administration system is not supported BIM based construction license BIM information from Seumter. Thus, despite the applicant is preparing a BIM model, they do not take advantage of BIM information in Seumter. In previous studies. We developed a BIM based building approval submission system. In this study, we verified the system that developed in previous research. As a result, requirement information input time reduction in Seumter system showed high satisfaction. But there was as low usability because building approval submission system cannot support some information for building approval in seumter. If the system will do utilization and management with the building approval system, the applicant can be using BIM base design document information and saving the time that takes at building approval submission. Study about the system improvement is required for application to building approval system.

The populations of major cities in Australia are increasing rapidly and facing an acute housing shortage. Traditional apartment procurement techniques involve lengthy lead-times and factory-based, or offsite manufactured (OSM) multi-storey apartment buildings may offer the opportunity to help fulfill the need by significantly reducing build times. Other advantages of OSM may include superior quality, low weight ratios, economies of scale achieved through repetition of prefabricated units, use on infill sites, sustainable design standards and better occupational health and safety. There are also positive labour and training implications, which may help to alleviate an industry-wide shortage of skills through use of semi-skilled labour. Previous uncertainties about the adoption of offsite due to the high capital costs and perception issues were generally based on pre-cast concrete structures, which are quite a different building type in terms of flexibility, construction, delivery and finishes. Identification of drivers and constraints assists in the determination of current industry status, allows for a benchmark to be established and future opportunities and directions for OSM to be determined.

With the sample of Middle East crude oil imported to South Korea, this study empirically analyzes the effectiveness of the risk management strategies using derivatives such as futures and options. Assuming the hedging period of one to twelve months, it considers a spot purchasing strategy, 1 : 1 futures hedge strategy, OLS-based minimum-variance futures hedge strategy, buying call option strategy, and collar transaction strategy. According to the ex-ante result, using the derivatives of futures or options makes lower the procurement costs when the crude oil prices is increasing. With the hedging period less than or equal to six months, the hedging strategy using futures turns out to be superior in terms of procurement cost reduction and hedging effectiveness improvement. In contrast, the hedging strategies of buying call option and collar transaction would generate better results when the hedging program last over six months.

Traditional bidding process and activities in public construction area has many problems in terms of the clearness and fairness of administration. And, it causes many cost consumption to suppliers. As part of the efforts to solve these problems, some public institutions developed the electronic bidding systems. But these systems have still problems in diverse aspects. Therefore, the purpose of this study is to analyze current bidding systems through literature survey, case study and process mapping methodology, to compare the result of the analysis with the developed electronic bidding systems and to suggest the improvement for the coming bidding systems. As results of this study, key processes and classified contract types about public construction bidding were identified. These can be applied by means of guidelines when public institutions are planning new electronic bidding systems. The composition of unified driving organization, the database development for information share and the standardization of national level for the new electronic bidding systems were also suggested.
