Factory-style plant production systems of various kinds are the final goal of greenhouse production systems. These systems facilitate planning for constant productivity per unit area and labor under various outside weather conditions, although energy consumption is intensive. Physical environmental control in combination with biological control can replace the use of agricultural chemicals such as insecticides, herbicides and hormones to regulate plants. In this way, closed systems which do not use such agricultural chemicals are ideal for environmental conservation for the future. Nutrient components in plants can be regulafied by physical environmental control including nutrient solution control in hydroponics. Therefore, specific contents of nutrients for particular plants can be listed on the container and be used as the basis of customer choice in the future. Plant production systems can be classified into three types based on the type of lighting: natural lighting, supplemental lighting and completely artificial lighting (Plant Factory). The amount of energy consumption increases in this order, although the degree of weather effects is in the reverse order. In the addition to lighting, factory-style plant production systems consist of mechanized and automated systems for transplanting, environmental control, hydroponics, transporting within the facility, and harvesting. Space farming and development of pharmaceutical in bio-reactors are other applications of these types of plant production systems. Various kinds of state-of-art factory-style plant production systems are discussed in the present paper. These systems are, in general, rather sophisticated and mechaized, and energy consumption is intensive. Factory-style plant production is the final goal of greenhouse production systems and the possibilities for the future are infinte but not clear.

Since the plant industry is a total business, it has great impact on the related industries and generates high value. However, in order to have a competitive engineering skills and capabilities, the plant industry requires long-term investment and a continuous strategic planning at the consortium level or national level. Also, a system needs to be established to share the information of the plant industry's overseas orders awarded and success factors. Thus, this study has conducted a survey and case study of the plant construction in foreign countries. Statistical analysis was performed and a basic data structure was built as a means of improving the future technological capabilities of the plant industry.

Space planning is one of the popular applications of VR technology including interior design, architecture design, and factory layout. In order to provide easier methods to accommodate physical objects into virtual space planning task, we suggest applying mixed reality (MR) interface. We describe our hardware and software of our MR system designed according to requirements of the application domain. In brief, our system hardware consists of a video see-through display with a touch screen interface, mounted on a mobile platform, and we use screen space 3D manipulations to arrange virtual objects within the MR scene. Investigating the interface with our prototype implementation, we are convinced that our system will help users to design spaces in more easy and effective way.

Since the amendment of the law on the private sector investment in social infrastructure in January of 2005, the government has been actively promoting Build-Transfer-Lease (BTL) projects. Notably, most new educational facilities have been built as BTL projects. For these facilities, the unit cost per unit area has been applied to predict construction costs. However, since construction costs are mostly managed after the detailed design phase, the costs can be estimated incorrectly. For this reason, cost management is needed in the planning phase, with a sound approximate estimate to prevent the wasteful use of funds. To address this shortcoming, this study aims to develop a quantity prediction model for education facilities using regression analysis in the planning phase. The developed model is focused on the required quantities of reinforced concrete and bricks. In order to achieve the objective, the data of 44 educational facility projects collected from Gyeonggi-do was used in the regression model. This study can be utilized by major stakeholders to accurately predict construction costs by estimating the appropriate quantities of reinforced concrete and bricks in the planning design phase.

This paper deals with a coal supply planning problem for power plants. We propose a mathematical optimization model to make decisions for coal pile sections, movement of reclaimers, and operation time of conveyor belts. The objective of the proposed model is to minimize the total operation time of conveyor belts and total movement time of reclaimers. The algorithm firstly selects a pile section by considering both the location of reclaimers and the stock amount on that pile section. And then the shortest path from the selected pile section has to be put into the operation schedule and check whether the total operation time is satisfied. Then finally the new schedule is updated. To this end, we have tested the proposed algorithm comparing with the general standard optimization package for the simplified problem SCSPP. From the numerous test runs for comparing with the existing coal supply scheduling methods, We see that the proposed model may improve the coal supply operation by reducing significant coal supply costs.

Shipbuilding is basically labor-intensive industry. It creates a number of job opportunities, but it is classified as a high risk industry like the construction industry. Shipyards show similarities in many aspects compared with the construction sites. There are many stakeholders of the HSE managements in the shipbuilding industry, such as ship owner, primary contractor and multi-layered subcontractors. The ship owners who are almost foreigners are treating strictly about safety and health. Therefore, it is necessary to development an appropriate HSE management systems and for the management systems it is desirable to information technology (IT) to accommodate these complex and complicated problems and situations. It was developed the ISP (Information Strategic Planning) as a HSE management system for the shipbuilding industry. It consisted of the environment analysis, the As-Is analysis and the To-Be design. In this study, the ISP is introduced and further it is suggested that it should be connected to system of HR(Human resource), PM(Plant maintenance) and KM(Knowledge Management) to make the HSE management system efficient.

There are numerous plant and animal species which are adapted to the conditioins of the urban environment. The objectie of landscape and nature conservation in cities can be considered as the perservation of these organisms as the basis for a direct contact between urban dwellers and the landscape elements. However, after 1980 in Korea, green and biotope oases started to develop in the center of the urban area, from which the surrounding population benefited, at least indirectly. Thus urban biotope mapping and biotope informatioin system as a specialized tool of urban ecological landscape planning will make clear the orientation for the preservation of species and renaturalizing measures. The results are as follows : 1) Biotope types in the study area were separated to 21 biotope. 2) The written description of the biotopes took place on the computerized forms. The basis for the uniform inclusion and description of all biotopes surveyed was a codeplan. Additional details were included on the urban biotope mapping. 3) The evaluation of the mapped biotopes was completed to the following aspect, namely " species diversity and biotope conservation value" and "nature experience value". 4) UBM and BIS represent an important basis for decision aid for the city administration within the context of the ecological urban and landscape planning process. 5) The methodology of UBM and BIS in this study area could be extended to whole urban area.to whole urban area.

Seawater desalination has vest interest in terms of ultimate water resources for the countries suffering lack of water supply. Water demand is steadily increasing due to the population growth and industrialization in Asia. The objectives of this study are to prospect the desalination market in Asia countries including China, India and Singapore, and to propose possible strategies of getting through Asia water market. Water supply in China is increasing up to $5,322,060m^3$/d in 2015. Northeast coastal areas such as Tianjin, Shandong, Hubei, and Liaoning are expected rapid increase for water demand. The investment of water supply in India would be 1.74 billion dollars during 2006 to 2015. Chennai, Kutch, and Pondicherry have possibility in introducing seawater desalination plants. Singapore is focusing on water reuse, and operating three NEWater plants (water reuse plants). BOT with total solution providing financing, construction, operation etc. is an adequate strategy to getting through China water market, while desalination plant project connecting with power plant is desirable in India. The cooperative system with Korea and Singapore creates synergy effect regarding planning and operating experience of Singapore and EPC ability of Korea.
