As the number of people going aboard is growing and technology is developed rapidly, Chinese customers are also getting better understanding about overseas products, and they hope to get less expensive and better ones, which leads to the growth of the online overseas purchasing agent service. In this paper, we tried to analyze the factors that impact the usage of online overseas purchasing agent service using the survey data. We found that customers pursue not only the reasonable prices but also enjoyment of shopping in the online overseas purchasing agent service. In addition, product scarcity and the information literacy of a customer were positively related with the use of online overseas purchasing agent service.

This study is a review study attempted to analyze the current situation of surgical robots based on previous research on surgical robots in the era of the 4th revolution, and to forecast the future direction of surgical robots. Surgical robots have made full progress since the launch of the da Vinci and the surgical robot is playing a role of supporting the surgeries of the surgeons or the master-slave method reflecting the intention of the surgeons. Recently, technologies are being developed to combine artificial intelligence and big data with surgical robots, and to commercialize a universal platform rather than a platform dedicated to surgery. Moreover, technologies for automating surgical robots are being developed by generating 3D image data based on diagnostic image data, providing real-time images, and integrating image data into one system. For the development of surgical robots, cooperation with clinicians and engineers, safety management of surgical robot, and institutional support for the use of surgical robots will be required.

As users use various services along with the rapid increase in Internet services, it may be difficult to manage accounts. To solve these difficulties, various password management applications are emerging. From a forensic point of view, password management applications can provide clues to obtain criminal evidence. The purpose of this paper is to acquire the data stored by the user in the password management application. To this end, we propose a better way to decrypt the encrypted data through reverse engineering, evaluate the security of the application to be analyzed, and safely store the data.

KEPCO proposes enhanced voltage management system that is a coordinate voltage control system between the hierarchical voltage control system and the slow voltage control system. It has been installing in Jeju island. VMS consists of a master controller, CVC (Continuous Voltage Controller) and DVC (Discrete Voltage Controller). CVC consists of main controller, FDMU (Field Data Measurement Unit) and several RPDs (Reactive Power Dispatcher). CVC has a control scheme with AVRs of generator to maintain the voltage of a pilot bus in a power system, DVC has a control scheme with static reactive power sources, like a shunt capacitor, a shunt reactor, ULTC and so on, to maintain the reactive power reserve of a power system and a master controller is executed to recover reactive power margin of a power system through coordinated control between CVC and DVC.

The aim of this paper is to review the environmental assessment of urban climatic factors relating to urban planning in Korea and Germany, and suggest efficient ways to consider climatic factors in the environmental assessment process for urban planning in Korea. For these purposes, current assessment systems concerning urban master plan and urban management plan in Korea were reviewed to know how urban climatic factors are assessed. Furthermore, two German cases of Strategic Environmental Assessment were investigated to know how urban climatic factors are assessed and considered in the urban and regional planning of Germany. Based on the results, efficient ways to consider climatic factors in the environmental assessment for urban planning were suggested from three aspects of factors, methods and available data for climate assessment.

Southern rough shrimp Trachysalambria curvirostris is exploited mainly by small shrimp beam trawl in coastal regions of Korea. To determine the size selectivity of a shrimp beam trawl for this species, a series of comparative fishing experiments was conducted in the sea adjacent to Geoje Island off the southern cost of Korea in June and November, 2010, using codends with four different mesh sizes(14.2, 17.8, 25.5, and 35.3 mm). The extended Share Each Length's Catch Total(SELECT) analysis method, based on a multinomial distribution, was applied to the fishing data to obtain a master selection curve. The model with the estimated split parameters fit the catch data best. The master selection curve was estimated to be: s(R)=exp(15.183R-7.872)/[1+exp(15.183R-7.872)], where the relative carapace length, R, is the ratio of carapace length to mesh size. The relative carapace length for 50% retention was 0.518, and the selection range was 0.145. The results suggest that codends with a larger mesh size allow more small-sized shrimps to escape.

The main purpose of this study is to find the factors affecting the consumer goods buyers' choice on e-commerce sites in Vietnam. By using the quantitative method, the paper examines the theoretical research model and tests four hypotheses. The sample was drawn from the population of e-commerce sites in Vietnam comprising about 1,000 respondents. This study used the questionnaire method to collect primary data to test the hypotheses. Data analysis of the questionnaire was done using SPSS. The results show that there is a correlation between personal preferences of consumers on colors and brands and their actual final choice on e-commerce sites in Vietnam. The most important factor affecting the consumer goods buyers' choice on e-commerce in Vietnam is the brand of E-commerce site, following by the color and position. Among all educational groups, respondents with a Master degree pay the biggest attention to the site's color attribute, and those with a Bachelor degree pay more attention to the brand attribute. Women pay much more attention to the location of the products on the screen than men, as do consumers with a PhD degree, over respondents with a Bachelor or Master degree, and foreigners over Vietnamese consumers.

The Korean government established 'the Act on Performance Evaluation and Management for National Research & Development (R&D) Programs' in 2005, and one year later constructed a master plan, 'A Basic Plan for the Management and Utilization of R&D performance' that focused on better diffusing the public R&D outcomes. In this study we propose a model of performance monitoring, evaluation, and management system for national R&D, which is based on a systematic approach and the logic model that has been prevalently used in planning and evaluating the public programs, to meet the purpose of the law and the master plan as well as to facilitate the diffusion of national R&D outcomes focused mainly on the industrial application technology. Furthermore, in order to use the model for the several applications, the model's specific measures which includes the quantitative methodologies such as analytic hierarchy process (AHP) and data envelopment analysis (DEA) are suggested in accordance with the existing system of the evaluation institution in Korea.

Nowadays PMIS (Project Management Information System) based on web is widely applied to communication, collaboration and community in construction jobsite for various organization such as subcontractors, general contractor, engineering company, supervisors and client. However, individual PMIS in jobsite is prone to be troublesome issue for integration and exchange of information regarding project management in corporate and may result in conflict of data application. The main reason should be lack of information strategy plan such as company master plan for information. This research shows a critical success factor that a big construction company of Korea establishes procedure and method for information strategy plan. In addition, It is to suggest how to be implemented PMIS architecture and execute business process innovation in corporate level. This research expects contribution that many construction companies reduce mistakes to be implemented management information system and to optimize system in corporate level.
