The trend of Development Projects has been changing through a few recent years. Small-scale development projects in the past were usually for building residences or officetel in a big cities. making lots of profits. These projects made not only lots of profits but also unbalance between the urban centers and the suburbs. So government made some regulations to prevent the things from being worse anymore, planned to develop the country in balance and began to lead large-scale development project such as Inno city and Newtown. At first, in this study, the phases and the characteristics of development project's change will be looked around. And then, after overview about PFV(project financing vehicle) used a lot in large-scale development projects will be seen, the better ways to use PFV in large-scale development projects are going to be proposed by considering the problems in PFV's conformation.

In this study, the effect of orchard expansion, structural improvement, and potential demand of the orchard scale-up project implemented since 2004 to strengthen the competitiveness of orchard farmers was examined. The results of the analysis are summarized as follows. First, looking at the effect of scale-up by checking the standard income data of the Rural Development Administration, it was possible to confirm the effect of scale-up in that the income per unit area increases as the scale increases. Second, through the scale-up project, the effect of structural improvement in transferring the orchards of the aged farm households to the younger farm households was confirmed to be 13 years old on average in the case of a sale business and 16 years old in the case of a lease business. Third, it was found that income increased at a statistically significant level after participating in the orchard scale-up project for major fruit crops such as apples, pears, and peaches. Fourth, it was found that age and cultivated area had a statistical effect on the probability of participating in the orchard scale-up project for farmers who did not participate in the project. The potential business demand using the estimated results was found to be between 25,203 and 37,089.

Large-scale construction projects require various license and technologies for the manufacturing and handling processes. Also, the whole life cycle business process management determines the success of the project. Then, the efficiency of the business conducted by stakeholders and their possessed technology should be enhanced in order to strengthen their competitive power. For this reason, many experts pointed out to focus on the improvement of the life cycle process and efficient management. Since it is very important to keep up-to-date data and utilize it for work during the long-term project to reflect changes in the large-scale project, the most important part of the project management in project is information change management. Therefore, the objective of this study is applying configuration management(CM) technique in order to managing change data generated for planning in early phase. The result of this research will certainly assist the large-scale project managers in the development of information change management system.

In this paper we describe current activities on the project Multi-Scale Modeling and Analysis of convective boiling (MSMA), conducted jointly by the Paul Scherrer Institute (PSI) and the Swiss Nuclear Utilities (Swissnuclear). The long-term aim of the MSMA project is to formulate improved closure laws for Computational Fluid Dynamics (CFD) simulations for prediction of convective boiling and eventually of the Critical Heat Flux (CHF). As boiling is controlled by the competition of numerous phenomena at various length and time scales, a multi-scale approach is employed to tackle the problem at different scales. In the MSMA project, the scales on which we focus range from the CFD scale (macro-scale), bubble size scale (meso-scale), liquid micro-layer and triple interline scale (micro-scale), and molecular scale (nano-scale). The current focus of the project is on micro- and meso-scales modeling. The numerical framework comprises a highly efficient, parallel DNS solver, the PSI-BOIL code. The code has incorporated an Immersed Boundary Method (IBM) to tackle complex geometries. For simulation of meso-scales (bubbles), we use the Constrained Interpolation Profile method: Conservative Semi-Lagrangian $2^{nd}$ order (CIP-CSL2). The phase change is described either by applying conventional jump conditions at the interface, or by using the Phase Field (PF) approach. In this work, we present selected results for flows in complex geometry using the IBM, selected bubbly flow simulations using the CIP-CSL2 method and results for phase change using the PF approach. In the subsequent stage of the project, the importance of effects of nano-scale processes on the global boiling heat transfer will be evaluated. To validate the models, more experimental information will be needed in the future, so it is expected that the MSMA project will become the seed for a long-term, combined theoretical and experimental program.

This research aimed to identify transition process of invigoration project of the small-scale schools and status of promoting project of multi-family housing for rental and vacant housing remodeling in Jeju-do, Korea. The results are followings. First, invigoration project of the small-scale schools had been started in villages communities themselves and was institutionalized to local government. To invigorate the small-scale schools was started vacant housing remodeling first in the village itself from 1992. After twenty years had passed, the project was institutionalized to local government in 2013. Second, to enact ordinances about invigoration project of the small-scale schools is the accomplishment of participations and activities of residents who predicted decreasing the number of students in elementary schools. These activities have influenced their communities positively. Finally, to supply multi-family housing for rental or to remodel vacant housing is more effective in increasing residents through influx of students of elementary schools. The average number of students increased from 56.8 in 2013 to 73 in 2018 in 30 elementary schools targeted for invigoration project of the small-scale schools. In particular, the effect in schools targeted the project of rental housing is shown more than schools targeted the project in vacant housing remodeling. In addition, low ratio in the number of closed school is shown in Jeju-do.

The information generated in large-scale and complex construction projects are transferred continuously and transformed into project products on the long span life cycle. Therefore, information flow management is related with the success of project directly. However, certain characteristics of large-scale and complex construction projects make the solving the problem more difficultly. Although several information retrieval systems support the information management system, it is not suitable to grasp information flows. Hence, we developed an information retrieval system specialized with the information flow based on a preceding research. The system consists of a relation-based database and the process information transferring relation inference application module. The system enables project managers to manage the entire project process more efficiently and each project member to work their own task being served the information flow retrieval results.

The purpose of this study is to analyze how the orchard scale improvement project affects the profits of apple farmers. For this purpose, the variable profit function of Apple was estimated using seemingly unrelated regression analysis. For the analysis, raw data from the Rural Development Administration's Agricultural Income Survey from 2015 to 2021 were used. Of the 1,009 apple farms, 95 farms participated in the orchard scale improvement project and 914 farms did not participate. The results show that the profits of farms participating in the project were found to be higher than those of non-participating farms, and as the cultivation area increased, profits tended to increase and then decrease. The results also indicated that below a certain size (19,462m²), the profits from project participation appear to be lower. The results of this study can provide useful information to the establishment of government policies and apple farmers who want to participate in the orchard scale improvement project.

This study aims to survey whether local governments have legislated laws and regulations on environment impact assessment system, to compare and analyze specific projects and their scale, assessment items, and procedures & discussion process, to identify issues and generate improvement plans, and to suggest a direction for future legislation to local governments that plan to legislate laws and regulations in the future. Major outcome of the study are as follows. First, terminologies used for environment impact assessment by local governments need to be unified. Also, laws and regulations need to be legislated soon. Second, in "urban development project" areas, a total of nine project areas including "quarrying of soil and stone, sand, gravel, and minerals" was essential common projects. A total of six project types were added or newly established compared to national systems. Among them, four project types were added within national-level project areas and two project types were not available under the national-level project areas and newly added due to the nature of local governments. Third, in terms of project scale, scale enhancement of "urban development project" was most common. Analysis showed that in case of clean natural environment such as Cheju Island, it is necessary to consider reinforcing project areas where development activities take place directly in forests or rivers such as "industrial base and complex development", "water resource development", and "development of tourism complex." Fourth, the discussion and review procedures of assessment reports were similar to those at government level. However, in case of Seoul city, it is required to write a "preparation plan" before drafting an assessment report. The city features partial introduction of scoping and screening, which allows to exempt discussion procedures if impact on environment is found to be minimal after drafting the assessment report. In case of national-level, it has a dual system that is split between Ministry of Construction and Transportation and Ministry of Environment. However, in case of environment impact assessment of local governments, it is a single system where city mayors and provincial governors are in charge of both project execution and environmental assessment. Therefore, the most important task is how to satisfy objectiveness and accountability.
