This study is a study on the application of a horizontal excavation machine system to improve constructability. In this study, the structural stability of non-covered temporary facilities was evaluated by comparing field measurements and numerical analysis. In addition, the appropriateness of the measurement results was analyzed by comparing and analyzing the results of numerical analysis with the analysis results applying the Gaussian probability density function to the measurement results. In this study, structural safety and long-term durability of the linkage were analyzed based on numerical analysis. As a result of the study, it was analyzed that the non-open cut method (H.A.S. method) of this study secures structural safety and constructability as the behavior in the actual construction process is more safe than the numerical analysis results, even if the uncertainty of the ground condition is taken into account.

Due to the development of information and communication technology, the global influence on politics, economics, society, and culture has grown. A major example of this impact on the economic sector is the growth of e-commerce, which increases both the speed and efficiency of businesses. In light of these new developments, businesses need to shift away from the misconception that information overwhelms to embrace the enhanced competitiveness that e-commerce provides. However, concern about fraudulent transactions through e-commerce is pertinent because of the loss in both critical revenue and consumer confidence in open markets. Current solutions for fraudulent transactions include real-time monitoring and processing, payment pending, and confirmation through SMS, E-mail, and other wired means. Our research focuses on the management of Fraud Detection Systems (FDS) to safeguard online electronic payment systems. With effective implementation of our research we hope to foster an honorable online trading culture and protect consumers. Future comparative research in domestic and abroad markets would provide further insight into preventing fraudulent transactions.

The hemA gene encoding 5-aminolevulinic acid synthase (ALAS) was cloned from Rhodobacter capsulatus, and its nucleotide sequence was determined. DNA sequencing data revealed one open reading frame coding for a protein with 401 amino acids that displayed high similarity to the amino acid sequences of other known ALASs. The hemA gene was then cloned and expressed under the control of constitutive promotor in E. coli. The recombinant E. coli strain was able to accumulate 5-aminolevulinic acid to 21 mM in the liquid medium supplemented with 45 mM glycine and 120 mM succinate. In addition, a marked effect of the pH of the culture medium on ALA production was observed, and the optimum pH for culture medium was determined to be 5.8-6.3.

Digital signage is becoming part of daily life across a wide range of visual advertisements segments market used in stations, hotels, retail stores, hotels, etc. The current digital signage system used in market is generally works on limited user interactivity with static contents. In this paper, a new approach is proposed using computer vision based dynamic audience adaptive cost-effective digital signage system. The proposed design uses the Camera attached Raspberry Pi Open source platform to employ the real-time audience interaction using computer vision algorithms to extract facial features of the audience. The real-time facial features are extracted using Haar Cascade algorithm which are used for audience gender specific rendering of dynamic digital signage content. The audience facial characterization using Haar Cascade is evaluated on the FERET database with 95% accuracy for gender classification. The proposed system, developed and evaluated with male and female audiences in real-life environments camera embedded raspberry pi with good level of accuracy.

Now, the goal of the third generation KTX project is to create a new species of high speed train in order to open a new era of high speed railway system in history by authentic Korean technology and innovative design. Now the third generation KTX, must go beyond the original stagnant paradigm and be positioned as an emotional resource which is creating a shift in the public's perspective of transportation and expanding the idea that transportation intersects the two distinct realms of culture and environment as well. In addition, the overall design should reflect the Korean culture and characteristics, simple yet resonant, both the interior space and the exterior fuselage should portray the dynamic heritage of Korea such as the powerful yet subdued energy of Jung Joong Dong. In short, through the symbolic key words in Korean, Dong(Dynamics), Mek(Pulse), Ryu(Flow), Gam(Sensibility), the third generation KTX design project aims to create an new identity of Korean high speed railway which can stand globally.

The purpose of this study is to identify critical factors facilitating JIT innovation process for Korean component manufacturers. In order to find the answers to this issue, this study has empirically studied the corelations among JIT innovation culture, competitiveness, and incentive factors. Cluster, ANOVA, and regression analyses were performed from 92 collected survey data. It has found that Korean component manufacturers strongly rely on their inner JIT innovation culture to improve competitiveness. It has also found that the organizational resource and managerial priority should be focused on establishing clear goals and objectives for improvement, and creating open atmosphere with respect to operational process.

Meteorological information is essential for the safe operation of aircraft. Many organizations both at home and abroad provide meteorological services for small aircraft flying at a low altitude as a part of open public service and have performed relevant studies. Recently, such a service has been expanded to an online platform in order to deliver information more efficiently. The ultimate goal of this study is to improve the meteorological service for small low-altitude aircraft that mostly travel a short distance for a short time. To achieve this goal, this study considered requirements for developing an effective information delivery system and conducted a survey of user requirements to derive the necessary information that could be used to develop a real service.

Many recent changes in medical area such as expansion of medical insurance, high expectation of people for medical service and the competition with foreign country open new area of medical service and hospital managements. Domestic medical personal have been doing their best for better medical service and more efficient hospital management. In other words, they are focusing on the renovation of organization culture, the reform of organization and operation process and building information systems. It has been more than 10 years since the first computer system was introduced in the domestic medical area. We have been trying to build more advance and more friendly computer systems. Recent advances of information technology could make this possible. In this paper, I introduce the system design of Integrated Hospital Information System include core technology, components of the system and important factors to be considered.
