Building information modeling (BIM) can improve to communicate with project participants by early construction involvement (ECI) from the beginning of the project. Therefore, they can minimize design changes and improve design quality and construction. However, because there is insufficient research on the scope and application level of BIM according to project delivery system and project characteristics, construction companies have efficiently not been using the BIM. Therefore, this study intends to conduct basic research as a basis for confirming appropriate BIM application and level according to project delivery system and project characteristics. To do this, we investigated the project delivery system and project characteristics of domestic and foreign projects that have successfully applied BIM, and compare and analyze them based on BIM application and BIM level framework derived from theory reviews and experts. Therefore, this study can be used as a basis for strategically establishing the scope and level of BIM according to project delivery system and project characteristics through the result of this study.

There is a growing need for ad-hoc analysis of extremely large data sets, especially at e-Commerce companies which depend on recommender application. Nowadays, as the number of e-Commerce web pages grow to a tremendous proportion; vertical recommender services can help customers to find what they need. Recommender application is one of the reasons for e-Commerce success in today's world. Compared with general e-Commerce recommender application, obviously, general e-Commerce recommender application's processing scope is greatly narrowed down. MapReduce is emerging as an important programming model for large-scale data-parallel applications such as web indexing, data mining, and scientific simulation. The objective of this paper is to explore MapReduce framework for the e-Commerce recommender application on major general and dedicated link analysis for e-Commerce recommender application, and thus the responding time has been decreased and the recommender application's accuracy has been improved.

This research examined the capabilities of KOMPSAT-1 EOC images for the application of urban environment, including the urban changes of the study areas. This research is constructed in three stages: Firstly, for the application of change detection techniques, which utilizes multi-temporal remotely sensed data, the data normalization process is carried out. Secondly, the change detection method is applied for the systematic monitoring of land-use changes. Lastly, using the results of the previous stages, the land-use map is updated. Consequently, the patterns of land-use changes are monitored by the proposed scheme. In this research, using the multi-temporal KOMPSAT-1 EOC images and land-use maps, monitoring of urban growth was carried out with the application of land-use changes, and the potential and scope of the application of the EOC images were also examined.

Arriving in the new space age, securing technology for fusion application of KOMPSAT-3·3A and global satellite images is becoming more important. In general, multi-sensor satellite images have relative geometric errors due to various external factors at the time of acquisition, degrading the quality of the satellite image outputs. Therefore, we propose a fine-image registration methodology to minimize the relative geometric error between KOMPSAT-3·3A and global satellite images. After selecting the overlapping area between the KOMPSAT-3·3A and foreign satellite images, the spatial resolution between the two images is unified. Subsequently, tie-points are extracted using a hybrid matching method in which feature- and area-based matching methods are combined. Then, fine-image registration is performed through iterative registration based on pyramid images. To evaluate the performance and accuracy of the proposed method, we used KOMPSAT-3·3A, Sentinel-2A, and PlanetScope satellite images acquired over Daejeon city, South Korea. As a result, the average RMSE of the accuracy of the proposed method was derived as 1.2 and 3.59 pixels in Sentinel-2A and PlanetScope images, respectively. Consequently, it is considered that fine-image registration between multi-sensor satellite images can be effectively performed using the proposed method.

The rapid progress toward the 4th industrial society has led to possibilities of fire increase. It is pointed out that, though initial fire suppression is emphasized, the current legal systems do not sufficiently recognize the importance of initial fire suppression. In order to resolve this, problems of the current legal systems and regulations, as well as fire-fighting facilities to be equipped according to the size of specific fire-fighting objects, were diagnosed. Also, suggestions for improvement were provided through comparative analysis with relevant laws and technical regulations of Korea and other countries. According to fire safety standards such as NFPA, IMO, ISO, and Russian standards, automatic fire extinguishers are to be installed as per the adaptability criteria of fire extinguishers and automatic fire extinguishers. In Korea, the "Act on Fire Prevention and Installation, Maintenance, and Safety Control of Fire-fighting Systems" cover the types and scope of fire fighting facilities that include specific fire protection objects, such as electric room, power room, and substation room. This study has identified that, in case of a place with a floor area of less than $300m^2$, the installation requirement is not clearly specified. Therefore, in this study, fire extinguishing equipment and automatic fire extinguishing equipment to be added for each sub-use application are proved to have fire extinguishing performance of Class A, Class B, and Class C, respectively. In view of the fact that, in overseas standards, all space except containing such materials as Deep fire, metal fire and peroxide, can be installed with fire fighting equipment, a legal system for specifying the capacity units of fire fighting apparatus by application is, in this study, proposed.

Barrier-free design reflects the attention of the disadvantaged groups. As a populous country with the largest population and the largest number of elderly people, China has made great progress in the field of the Barrier-free. The scope of this thesis is from the 1980s to 2012 in China, studying the development process of China's barrier-free design standards by comparing the two barrier-free design standards implemented in the history of such design. In this paper, the two standards are compared and analyzed in the following aspects, which are the numbering, chapters, scope of application, applicable objects and purposes, and so on. Compared with the 2001 barrier-free design standards, the 2012 one can be concluded that the development of barrier-free design in China has been accelerated, the scope of application has been widened than before, the content has been supplemented, and restrictions on terms have been reduced.

The primary purpose of the general duty clause is to offer an extra measure of protection to employees in the workplace. Most standards implemented under OSHA are targeted at a specific hazard. The general duty clause, however allows inspectors to cite employers for exposing its employees to a recognized hazard that has not been specifically addressed in the regulations. Congress intended the general duty clause to be a limited means of advancing the purposes of the OSHAct. But OSHA has not always regarded the general duty clause as the limited means for protecting the safety and health of employees that Congress intented. OSHA attempted to expand the scope of the general duty clause, at times improperly, to make it a more flexible enforcement tool. OSHA's interpretation of each of the restrictions on the scope of the clause has changed over the years. In recent years the general duty clause has been utilized as a sometimes controversial mechanism for enforcement of safety guidelines that have not yet been specifically addressed by statute or regulation. The most notable example of this was application of the general duty clause to ergonomic hazards.

Through the application of Quality Assurance(QA) techniques in R&D activities, we can approach for cost reduction and productivity improvement with high reliability. Application of QA systems in R&D in developed countries were studied, a enquete survey was performed to investigate researcher's understanding of QA in R&D. As a result of this study, it is considered desirable that QA system be applied partially to the feasible work areas at first, and the scope of application be enlarged to extended areas, later. For these aims, various and feasible QA system should be developed and established. As the need for quality assurance in R&D is expected to be increased continuously in the future, it is imperative for us to be prepared for the application of QA system in R&D activities.
