  • This paper aims to suggest ways of institutionally improving standards that must be applied when installing Water Reclamation/Reuse (WRR) system based on efficiency analysis. Currently, the standard for WRR system establishment requires that the system should treat more than 10% of used water in the building of over $60,000m^2$ in total area of all floors, but our research has found that it would be more effective to change the standard to $150-m^3-per-day$ reclaimed water or the total area of all floors of $30,000m^2$ ($50,000m^2$ in the case of an office building). In other words, what this paper suggests is not a one-size-fits-all standard based on the total area of all floors, but a reasonable and flexible standard that takes into account efficiency and a unit water usage according to a building's purpose. Furthermore, this paper recommends a new WRR standard that can be applied to large-scale land development for housinglots, like the New Town. The recommendation is based on the economic analysis that the WRR system will ensure efficiency only if the amount of reclaimed water is over 4,000 tons per day, which corresponds to 4 millions square meters of housinglots. Regarding the size of the established facility, this paper suggests changing the standard, which is now set at over 10% of water usage, to what is relative to the total amount of use of reclaimed water in order to ensure efficiency and promote use of reclaimed water. In addition, this paper proposes that governmental support should be offered not only to facility owners, who are recipients at present, but also to facility builders. By doing so, those who donate a facility to the government, central or local, after building it, can be provided with substantial aid. Therefore, the application of the institutional improvement suggested in this paper is expected to create environment-friendly living conditions and boost the quality of life by encouraging people to secure water resources efficiently in buildings, and in a wider range, in cities.

  • Up-to-date manufacturing companies have faced a market-driven environment of pull production order. There should be a difference in operating manufacturing resources according to the type, quantity, and delivery time of manufactured products, because the process situation in pull production is changed by customer orders. And it should be taken into account from the stage of preparing for production such as process design and the placement and utilization of manufacturing resources. However, the feasibility of production plans is limited because most of small manufacturing businesses make production/supply plan of the parts and products assuming that equipment abilities in scheduling is sufficient without managing process standard information systemically. In this study, a discrete event simulation system based on BOM (bill of material), that is F-OPIS (online productivity innovation system), is introduced and a case study on application of the system leading to improving productivities is presented. F-OPIS deals with a decision-problem on production management and it is specialized for small-and- medium sized manufacturing companies. The target company of this case study is a typical small-and-medium sized manufacturing company in Korea, that produces various machined parts. The target company adopts make-to-stock production management to prevent tardy delivery because of fluctuations in demand. Therefore, it is required to apply an efficient inventory control solution for improving productivities. In this paper, based on the constraints of working capacity of manufacturing resources, the bottleneck process is analyzed as production conditions are changed. Consequently, an improvement plan is proposed, that eventually enhances overall utilization rates of resources in the bottleneck process and reduces overall production lead-time and inventory level.

  • Current supervision systems have been changed by the demands of social, physical and institutional environment, and have a role of preventing safety accident and in improving the construct ability through the analysis of issues in quality, time, construction, safety, and environmental management. The public sector "Construction Technology Management Act", a general and private sector "Building Act" and "Certified Architects Act", the residential building "Housing Act" are dealt with supervision systems, respectively, but private small building construction is excluded from the discussion of the main targets because of their relatively small scale and the lack of social interests, Thus, this study focused on the small buildings for improving the non-resident supervision systems. Survey results revealed that the non-resident supervisor needs to be selected not by clients but by officers in order to obtain its publicity. Based on the proper selection and execution of the supervision system suggested in this study, the potential effects can be summarized as 1) recovering of publicity, 2) correcting abnormal practice, and 3) realizing design intention for increasing the public value of buildings. In addition, findings in this study will be effective to amend current non-resident supervision systems for improving the quality of buildings and communities as well as for adopting the environmental-friendly energy-efficient smart building technologies.

  • Over the last few years Total Quality Management (TQM) programs have hem widely adapted by Korean manufacturing firms to improve their productivity, competitive edge and product quality levels. The purpose of this study is to evaluate the level of importance placed on four key TQM factors (customer satisfaction, strong management leadership, continuous improvement, imployee involvement and participation) used during the implementation of korean manufacturing TQM programs and to assess the effectiveness of those key factors in improving the performance of the firms. A Questionaire was developed and sent to senior managers in manufacturing organizations throughout korea. This survey asked qustions regarding 1) the firm's business environment and TQM program development 2) subcomponents of the key factors and 3) the effectiveness of the TQM program at improving the performance of the organization. The survey data were analyzed to determine the degree of correlation between each of the factors and the effectiveness of the TQM programs. This study demonstrated that the TQM programs were instrumental at improving the performance of the firms studied, and that the improvement was positively correlated with the length of time that the program had been implemented and the planned duration of the TQM program implementation. It was found that the person-oriented elements of management leadership and employee involvement were positively correlated and predictive of the success of the TQM Program, while the process-oriented components of customer satisfaction and employee involvement were not useful predictors of the effectiveness of the TQM program implementation.

  • For the rapid development of embedded software, a variety of development tools have been developed. But, the embedded software developers do not use the available tools fluently and do not improve software productivity as expect because there are short of supporting utilization convenience of development tools. In this paper, we suggest a tool of building custom development environment for improving the utilization convenience of embedded software development tools. The custom development environment helps developers to rapid selection and access of appropriate tools required to develop the embedded software on the specific embedded system. In addition, it enables developers to handle the outputs from development tools associatively. Moreover it is very flexible in extension and integration because it's implementation based on Eclipse technology. We also perform the evaluation of our tool and successfully validate the utilization convenience of embedded development tools. Therefore, we expect that this tool enables developers to use the embedded development tools efficiently, and then it help improving embedded software productivity.

  • This is a comparative study on the policy of Korea and Japan for improving upland farming mechanization. Purpose of the study is to set a policy direction of improving efficiency of farm management by using agricultural machinery. Research topic is the agricultural mechanization policy at the national level. The research attempts to classify mechanization policies into framework plan, R&D, rent and lease program, upland farm promotion policies. Major features of the comparative analysis are followed. First, there is a similarity between policies of Korea and Japan in terms of the aim of framework plan and other policies settings. However, Japanese policies focus more on the joint management of farming than Korean policies. Japanese policies take an entire system covering from farm to market into account. Second, Japanese policies have much attention to the agricultural organizations such as corporate, cooperatives that are eligible for using agricultural machinery. This is different from Korean policy. Thus, upland farming mechanization policy needs to set priority, and to have systemic approach. Also, upland farming mechanization policy has to be facilitated in accordance with producer organizations and their marketing strategies.
