Korean urban development cooperation is gradually expanding into Latin America and the Caribbean (LAC) region, but strategies to encourage domestic market players to participate are insufficient. This paper investigated the Colombian urban planning system, urban development projects, and Korean projects in Colombia, which leads to implications for international cooperation in LAC. This research, first, compares the national and regional urban planning systems of Colombian major cities, Bogotá and Medellín. Second, case studies are carried out with a land readjustment project, a Macro project for large-scale public rental housing supply, and urban development cooperation between Korea and Colombia. By doing so, the role and the directions for Korean urban development cooperation with LAC such as Colombia are discussed and proposed. The findings suggest, first, aid projects through Official Development Assistance (ODA) should establish urban networks in recipient countries. Second, it is necessary to understand the financing structure for urban development cooperation projects that are different from infrastructure projects. Third, the successful case of urban development cooperation should be demonstrated by making the development period and size optimal and manageable.

System Integration Projects, especially in public sector, have a tendency of growing in size and duration. Under such environment the effects of IT personnel turnover becomes a serious problem. In addition a high rate of turnover hinders shill accumulation and competitiveness obtainment. In this research we explored the reasons of turnover by way of tracing IT personnel who have involved in large-scale SI projects and moved or quit before the completion of the projects. Based on previous research we identified three dimensions of variables that affected turnover : task-related dimension, human relations dimension, treatment-related dimension. We used these dimensions as a guideline for the interview and questioning exploration. Implications from the research for improving IT Personnel management are also elaborated.

In Korea, many mixed-used development projects(MXD) in mega project size are currently active. As these mega projects require long-term construction and execution and involve by different subjects in different fields, their completion breeds various problems, such as conflicts among project participants due to their complicated interest relationships and inaccuracy in predicting the economic performance of the projects due to inappropriate facility capacity planning. To solve these problems, it is essential to apply value engineering (VE) at the planning phase of the project, which can result in the best possible cost reduction and improvement of project performance. However, not many projects are actually implementing VE because of the lack of available information, as well as the limitations due to uncertainty in the early period of project execution. Therefore, this study aimed at proposing VE Team Building, Quality Model Performance Indexes, Space Model so as to resolve common mega project problems and overcome VE application limitations at planning stage. The result of this study is expected that the data can be utilized as basic data to apply VE at the planning phase of the large complex projects.

The Python language widely used in artificial intelligence (AI) projects is an interpreter language, and errors occur at runtime. In order to prevent project failure due to errors, it is necessary to handle exceptions in code that can cause exceptional situations in advance. In particular, in AI projects that require a lot of resources, exceptions that occur after long execution lead to a large waste of resources. However, since exception handling depends on the developer's experience, developers have difficulty determining the appropriate exception to catch. To solve this need, we propose an approach that recommends exceptions to catch to developers during development by learning the existing exception handling statements. The proposed method receives the source code of the try block as input and recommends exceptions to be handled in the except block. We evaluate our approach for a large project consisting of two frameworks. According to our evaluation results, the average AUPRC is 0.92 or higher when performing exception recommendation. The study results show that the proposed method can support the developer's exception handling with exception recommendation performance that outperforms the comparative models.

To have successful execution of a development project on large scale, it is the most important to improve communication problems between project stakeholder. In this study, we design and implement project integrated management tools that improve the problems. In order to design and implement the tools, we gathered and arranged requirements based on the ISP data from S corporation and the problems of 23 projects which was executed in recent 2 years in a communication perspective, and then we conceptually design and propose the tools. We defined major parts of the functions and the architecture related to communication among the proposed architecture model, and we proposed process and detail functions to execute major functions. This study shows the possibility through a qualitative valuation to improve validation of the architecture model and a quantitative analysis in a communication perspective.

Project Financing (PF) development project is the type which influences national economy and building industry largely because it is exerted by using borrowed money from many kinds of investors and huge amount of financial raising. Many domestic PF projects are focused mainly on the profit maximization lacking in a sufficient feasibility study. Nowadays many projects are suspending due to the global finance debacle and stagnation of real estate industry. Therefore, in this paper, risk factors of PF project are deducted and Key Success Factors (KSFs) are derived through Factor-Analysis and qualified using Fuzzy-AHP method. And through the evaluation of the derived success factors in real projects, a strong correlationship has been identified between the score of each PF success factor and the level of success and/or expected rate of return (ROR). So, the result of this paper can help decision makers of the PF projects make a better decision and give a meaningful guidance in achieving successful PF projects.

Manufacturing process of large-scale 3D computer animation is becoming sophistication, ramification because of development of manufacturing technique and extravagant budget. Form of manufacturing pipeline has been variously changed to production type, manufacturing scale, manufacturing form. But it is time that renewed discussion is needed because change and development for the organization is insufficient in small manufacturing company. The project aims to try to help understanding for manufacturing pipeline of internal small-scale 3D animation and to find a plan of organization for internal small-scale production of the real situation. Organization model and methodology of manufacturing pipeline of small manufacturing company is not absolute because it is enough possible to be changed to inclination of the project and its environment. People must fully understand the purpose for organization of manufacturing pipeline of 3D computer animation and it must be organized to the situation for small-scale production so that every worker in production can share the information perfectly.

The construction projects are larger and more complex, and so the construction accidents are bigger. Recently, the studies for reducing the human errors are researched to decrease the construction accidents. The purpose of this study is to analysis a correlation between the safety education and human errors by construction workers. The results showed that the frequencies of safety education in large sized construction projects are more than these in small sized construction projects. However, all of construction projects conduct lower times of safety education than the regulated times. In addition, it is revealed that the human errors of construction workers in large sized construction projects are being lower in accordance with increasing the safety education times. In small sized construction projects, however, the human errors of construction workers are increasing according to more times of safety education, reversely. This study should help to reduce the accidents in construction projects.

Today, the scale of the computer software market has increased, and massive sized software has been developed to satisfy diverse requirements. In this context, software complexity is increasing and the quality of software is becoming more difficult to manage. In particular, software reuse is important for the improvement of the environments of legacy systems and new system development. In this paper, we propose a method to reuse modules that are certified by quality. Reusable levels are divided into code area (method, class, and component), project domain, and business levels. Based on the coupling and cohesion of software complexity, we propose a reusable module extraction mechanism with reusability metrics, which constructs a visualization of the "reusable module's chunk" based on the method and class levels. By applying reverse engineering to legacy projects, it is possible to identify reusable modules/objects/chunks. If these modules/objects/chunks are to be reused to develop an extension system or similar new system, we need to ensure software reliability in order to reduce the time and cost of software development.
