There are many limitations in applying agile methodology to projects so far. In fact, projects overlap with other development methodologies and management processes, resulting in confusing progress, while there are often cases where the benefits of agile cannot be embraced due to a lack of understanding of agile processes and the organization's inability to adapt to change. It is an important role of information system development to improve the quality of agile application projects by discovering the problems and improvements in these cases. In this paper, we analyze the differences between existing development and project management methods and agile, and analyze agile processes. The optimal agile methodology was proposed by analyzing and applying methodologies established and applied mainly by large domestic development companies. In addition, the effectiveness was verified through a questionnaire of IT experts, and the result of the questionnaire was verified to be 4.75 points on a 5-point scale.

This paper presents results from a computer-aided systems engineering application to system development projects. RDD-100 version of ALC Inc. was used in this work. The framework adopted in the study takes a unified approach to the system design and the process management associated with it, thereby coherent and full traceability between them is maintained. Conventional system engineering process supported by the tool is adopted in the system design. On the other hand, the same tool is also used to the systems engineering management to get full traceability between system design data and engineering management data. It is greatly helpful in managing many sub-contractors in the sense that the traceability can help identify the sub-project responsibility as well as the objectives of the project in coordination with interface requirements. We conclude with the advantage and limits of our unified approach.

The tire production facility is a large-scale construction with the complexity of a manufacturing process. The process utilities should be wide-ranging as an effective arrangement of them is highly important. All the necessary information should be clarified together with the manufacturer at the basic planning stage, and this design should be developed to comply with the local culture and regulations. It is important to carry out more advanced engineering in terms of process, cost and quality, even if it is difficult to standardize due to the cultural and geographical conditions and regulations. The key point is to reflect all the given conditions and make a clear design during the design stage, to eliminate the problems after the construction has begun. Another key point is the delivery system, which must be totally managed from the initial design stage until the construction stage by proven companies. Flexibility, quick action, and single responsibility will be the fundamental features in all the steps of the project.

The objective of this study is to investigate actual conditions of terrestrial vegetation part in Environmental impact statement, and to prepare a proposal for the efficiency of Environmental Impact Assessment. 13 E.I.S.s made out during 1996.6-1997.5. have been chosen and analysed with respect to scope of survey, item of survey, method of survey, and result of survey. Actual conditioins of terrestrial vegetation part in E.I.S. are summarized as follows : 1. The mean number of total participants in drawing up E.I.S. is 26.0 persons, that of participants in terrestrial vegetation part is 2.3 persons. 2. In case of planar project, the mean of scope of survey is 16.1 times as large as area of project . In case of linear project, the scope of survey has been determined arbitrarily. 3. The most part of survey has been dependent on literature, and field survey has been practically neglected. 4. Results of survey mostly missed the point that E.I.A. pursues. And proposals are as follows : 1. Participants in terrestrial vegetation part in drawing up E.I.S should be increased. 2. It is necessary to subdivide scope of survey in view of difference between planar project and linear project. 3. As for item and method of survey, field survey should be specially reinforced. 4. Several sheets of map as results of survey should be included in E.I.S. The vegetation map, the D.G.N. map, and the planting map should be included and drawn by smaller scale as possible.

As shown in the accident analysis from 2007, it has been found that causes of accidents on large-scale projects are different from those found in general construction projects. A 300-question survey regarding systematic and practical aspects of safety problems at construction sites was distributed to ten (10) different companies. Participants were to respond subjectively, so that the results could be used to assemble the first formal questionnaire survey. They were collected and compiled by an advisory committee for this study. The resulting surveys were then sent to the division chiefs of the top 100 construction companies in Korea, in order to improve the response rate. The Department of Safety & Health Direction, and the :Ministry of Labor, ROK sent the same sheets to medium and small construction companies that placed within 101-200th of all Korea construction companies. The above safety engineers were classified into four (4) levels, from 1st to 4th, followed by the project dollar amount and risk level. Formulae were developed to assign safety engineers to construction sites by engineer level, the project dollar amount, and the project risk level. Conclusions are summarized as follows: 1) Reviewing the assignment system of experienced safety engineers to large scaled projects - The more experienced the engineers assigned to a project, the higher the level of accident prevention. 2) Enforcing the assignment of advanced level safety engineers to large-scaled sites - At least one advanced-level safety engineer should be assigned to construction sites with projects valued at $15million USD (15,000,000,000). 3) For assigning safety engineers by risk level - Twenty models have been developed to calculate the number of safety engineers to be assigned by risk level. In the future, risk level for each job should be established by the government (as is now the practice in Germany).

The Comprehensive Rural Village Development Project, a resident-led bottom-up regional development project, began in 2004. This study investigated difficulties and problems in the operation process after the completion of the project, and future improvement plans, through in-depth interviews with the former and current chairman of the steering committee, steering committee members, and office managers, targeting three regions in Jeollanam-do, 15 years after the completion of the project. As a result of the survey and analysis, it was effective in improving the living environment and characteristics of each village and revitalizing the area. And while there were well-run facilities depending on the type of project, there were also many idle facilities. In the case of communal facilities, there was a high possibility of problems in operation and management when the scale of the new building was large. Conflicts occurred between villages in the process of independently operating the area after the completion of the project. Therefore, it is necessary to provide an S/W project program to prepare for after completion. Local governments need to utilize City and County Capacity Enhancement Projects to support regional leaders to participate in educational programs after completion and provide guidance and supervision for village operations.

Sensors collect information for Internet of Things (IoT)-based services. However, indoor construction sites have a poor communication environment and many interfering elements that make it difficult to collect sensor information. In this study, a network was constructed between a Bluetooth Low Energy (BLE)-based IoT device based on a serverless IoT framework and a router. This experimental environment was applied to large- and small-scale indoor construction sites. Experiments were performed to test the communication performance of BLE-based IoT devices and routers at indoor construction sites. An analysis of the received signal strength indication (RSSI) graph patterns collected from the communication between the BLE-based IoT devices and routers for different testbed site situation revealed areas with good communication performance and poor communication performance due to interfering factors. The results confirmed that structural components of the building as well as the materials, equipment, and temporary facilities used in indoor construction interfere with the communication performance. Construction project managers will require improved technical knowledge of IoT, such as optimizing the router placement and matching communication between the router and workers, to improve the communication performance for large-scale indoor construction.

구조실험에서 정확성과 효율성을 높이기 위해서는 적절한 실험장치를 적용하는 것은 중요한 요소이다. 특히, 대규모의 구조 실험에서 적절한 실험장치는 비용과 시간을 절감할 수 있다. 액츄에이터와 유압잭 및 UTM은 실험체의 휨 능력을 평가하는 데 일반적으로 적용되고 있다. 그러나, 대규모 실험체에서 다점 다하중 가력하중이 적용되어야 하는 경우에는 기존의 UTM 등을 이용하는 실험방법은 정확한 하중을 가력하기에 어려움이 많다. 이를 해결하기 위하여 본 연구에서는 실험결과의 정확성과 효율성을 높이기 위하여 기존의 실험장치로 조합된 새로운 방법을 개발하였다.
