Long-term behavior analysis considering construction sequence should be performed in the design and the actual construction of reinforced tall buildings. Most of the analytical studies on this subject, however, has not been applied directly to the structural design and the construction caused by the simple approach. As the axial force redistribution of shores and columns is time-dependent, the actual construction sequence with the placement of concrete, form removal, reshoring, shore removal, and the additional load application is very important. Object-oriented analysis program considering construction sequence, especially time-dependent deformation in early days, is developed. This system is composed of input module, database module, database store module, analysis module, and result generation module. Linkage interface between the central database and each of the related module is implemented by the visual c# concept. Graphic user interface and the relational database table are supported for user's convenience.

Objective : The purpose of present study was to determine effects of task oriented action observation training on dexterity of upper limb function after stroke. Training was progressed to imitation and intensive training after observation to required action in ADL. Method : 15 stroke patients were selected and one group pretest-posttest design was applied. Targets observed performance actions of task orientated task through a video and limitated action repeatedly, Training was performed 3 times a week and 20~30 minutes for each round for 3 weeks. Manual function test and 10-second test and Box and block test were performed for a dexterity of upper extremity motor function, Modified Barthel index and Motor activity log were performed for ADL. Result : After the training, a dexterity of affected upper extremity motor function of the target showed significant difference between before and after intervention, ADL showed significant improvement between before and after intervention. Conclusion : Task orientated Action observation lead a positive effect of recovering a dexterity of upper extremity motor function and ADL. Therefore, this study suggest a action observation training as one strategy of an intervention type of th e occupational therapy.

In this paper, we develop the next generation mobile system based on SBC(Server Based Computing). SBC is one of the popular topic and only one server system is used as multiple personal systems with a terminal, a monitor and a keyboard. The advantages of this system are easy-upgrade, low costs and convenience for each user. But it is difficult to design and manufacture the multimedia streaming system and devices control system for external devices. In this paper, we represent and develops the Mobile system based on SBC and the test performances shows that our system has good performances of multimedia system and security for internet.

The aims of this study are to provide an overview of research trends on user interface in the field of Information Science. This study attempts to address the following four questions: 1) what are the research areas or subject topics, 2) what are the patterns of user interface publication, 3) what methods are often used to what topics, and 4) what are the changes in the subject topics and research methods over the past ten years. It analyzed a total of 128 research articles published in four Korean LIS journals and one U.S. journal. The study also reviewed 72 articles published in Korean journals for identifying research trends. The study found that the most productive areas were 'web site evaluation', followed by 'search interface', 'information design' and 'interaction style design'. The most frequently used research methods were survey methods, followed by unobtrusive methods, and experiments. Journal of the Korean Society for Information Management published the most articles on research of user interface. The research of user interface was conducted more frequently in the early 2000s than later years.

Recently, railway has been pointed to the efficiency of transportation, rapid transit, and comfortable train ride. the construction of railway near the downtown area and station building are increasing for maximization of utilization and convenience. but the heavy of transportation and rapid transit lead to increase noise and vibration. the noise and vibration of railway may cause the civil appeal, decline in the serviceability and insufficiency of environmental standard. Therefore, the solution to avoid environmental matters becomes one of the most important factor in constructing railway. In this study, floating slab system which is one of the solution to avoid noise and vibration in railway has been introduced, and the concept of preliminary design and vibration absorber of floating slab system according to the isolator has been introduced.

This paper explored how to design amobile application for Korea's traditional markets based on O2O service and data science technologies. In order to cover a broader scope of customers, diversify the ways to sell products, and increase the profits of Korea's traditional markets, the application bridges online customers with offline stores at traditional markets and augments both convenience and accessibility. Beyond the typical face-to-face interactions between customers and sellers at traditional markets, this application offers mobile payments and personalized recommendations of nearby stores and preferable products using Beacon and datascience technologies. Moreover, it offers multi-language support for foreign customers who are not familiar with Korea's traditional markets and the products sold there. In conclusion, using O2O service, which is a rising trend among prevalent platform technologies, this study proposed a new e-commerce model for Korea's traditional markets to promote market expansion.

Meta search engines have been used as the first engine because they let users several search engines at once for their queries and give them the search results. The purpose of this study is to examine the features and functions of 17 meta search engines in order that it helps users select and execute effective searches on meta search engines. Each selected engine is analyzed based on the criteria evaluating both meta search engines and general search engines. The results show that each meta search engine has its own characteristics while there are common features among them. It is expected that the results of this study will help users utilize meta search engines and provide meta search engine designer basic ideas.

Worldwide Electric Vehicle (EV) sales are rapidly increasing. But in many cases, charging locations can be found within or near downtown area of the city which makes EV users living outskirts of the city very difficult to establish their daily EV charging routines. In order to improve this situation, we have come up with a daily EV charge service connected with convenience stores and restaurants within reach of most EV users living in South Korea. We aim to allow users to charge their EVs while they shop and eat, just as if they charge their smartphones at cafes and restaurants. We have gone through user diary research and focus group interview research to figure out current user's concerns regarding charging and maintenance of EVs and applied the findings to our proposed service design.

For driver's convenience, the ACC(Adaptive Cruise Control) requires a system which determines the direction of vehicles and controls the vehicle to keep the distance among the automobiles constant. This paper describes the microstrip array antennas designed to operate at 24 GHz, and used as a direction indicator of moving vehicles. 8${\times}$2 transmit array antenna with wide beamwidth, 8${\times}$4 receive center array antenna, and two 8${\times}$8 receive array antennas with narrow beamwidth were designed and fabricated. Measurement results for the arrays showed that the azimuthal beamwidth is 50$^{\circ}$and the gain is 16.7 dBi for the transmit array antenna. For the receive array antenna, the center, the left, and the right array antenna have beamwidths of 20$^{\circ}$, 13$^{\circ}$, 13$^{\circ}$respectively, and have gains of more than 20 dBi. The left and right array antenna have the beam tilt angle of ${\pm}$18$^{\circ}$. The measured radiation patterns showed a good agreement with the simulated patterns, and the designed array antennas are suitable fur detecting 3 directions of the vehicle within the scan angle area.
