Technical documents are important research outputs generated by knowledge and information society. In order to properly use the technical documents properly, it is necessary to utilize advanced information processing techniques, such as summarization and information extraction. In this paper, to extract core information, we automatically extracted the terminologies and their definition based on definitional sentences patterns and the structure of technical documents. Based on this, we proposed the system to build a specialized terminology dictionary. And further we suggested the personalized services so that users can utilize the terminology dictionary in various ways as an knowledge memory. The results of this study will allow users to find up-to-date information faster and easier. In addition, providing a personalized terminology dictionary to users can maximize the value, usability, and retrieval efficiency of the dictionary.

In this paper, we design and implement the Walking Life Festival application, which is based on the Android platform and provides information about domestic travel destinations and regional festivals in South Korea. This application utilizes various sensors found in smartphones, including the Step Counter sensor, Step Detector sensor, Acceleration sensor, and GPS sensor. Additionally, it makes use of Google Map API and Public Open API to offer information about domestic travel destinations and local festivals. The application also incorporates an automatic login feature using the Shared Preference API. When storing login information in the database, it encrypts the input plaintext data using a hash algorithm. For Google Maps integration, it creates objects using the Google.maps.LatLngBounds() method and extends the location information through the extends method. Furthermore, this application contributes to the activation of the domestic tourism industry by notifying users about the timing of local festivals related to domestic travel destinations, thus increasing their opportunities to participate in these festivals.

This study investigated organizational changes in technical services of university libraries and analysed librarians' perception on the changes of technical service department by the survey to 32 technical service librarians. It also identified several factors that have changed work environment of technical departments such as the shared cataloging and outsourcing, and electronic resources in various formats and creation of metadata for these resources. Most librarians agreed that university libraries have to foster technical librarians' professioanal development to cope with emerging changes of technical services. They also recognized that the integration of traditional cataloging and metadata management is an important issue of orgranizational changes. Contrary to librarians' perception, technical service librarians were not fully awared of the procedure of metadata related works in other departments. Furthermore metadata creation and management were also conducted in several departments of libraries without proper control.

In this study, we developed a mobile home robot using a face recognition method using a camera attached to a raspberry pie. It receives the real time image through the camera attached to the raspberry pie, recognizes the face of the person, and distinguishes the operation of the smart cool air temperature device according to the result. It is expected that the robot will be able to increase the energy utilization efficiency by allowing the robot to operate in cold and hot winds only where there is no human being, instead of operating the hot and cold air conditioner.

In recent years, with the focus on the younger generation, a minimal life that pursues a simple and light life has attracted attention, and a product that occupies a small space and has high practicality attracts attention. Therefore, a lot of studies on small but realistic products are going on by combining plural products into one. In this study, we developed a smart stand that can save space on the desk. The stand is equipped with a smartphone holder, humidifier, negative ion generator, and speaker functions. Because of this study, it is expected that the efficiency of space and economy will be improved in a small house of one person.

In this study, we developed software for portable lifter using Android application for stability of portable lifter which can load freight easily. Arduino Uno R3 boards were used for this purpose. The existing portable lifts were disassembled to mount the Arduino Uno R3 board and circuit, and to send and receive signals via Bluetooth communication. This study can be expected to contribute greatly to the safety work of logistics activities.

The function of the direction indicator is essential for the safety of bicycle trips and commuters. In this study, the direction indicator function was developed on the prefabricated bicycle using the Arduino. With the simple function of the Arduino, you can attach a switch to the handle to turn the direction indicator on and off. Since it is a simple function, it is judged that it is suitable for the maker activity that can make it by DIY by oneself having a bicycle. In this paper, we have opened the possibility of attaching a lot of services to bicycles through the proposed functions.

In this paper we analyse performance of value strategy and moving average method among the non-financial listed companies whose fiscal year ends at December in the Korean Stock Exchange between 1996 and 2005. And we analyse combination investment performance of value investment and moving average method. After the analysis objective enterprises divide with the value stock and the growth stock, in accordance with moving average method we divide ascending stock and descending stock. And we compose 6 portfolios with combination of value stock, growth stock, ascending stock and descending stock. Using the difference of investment performance of these portfolios, when fundamental analysis and technical analysis method all considering we measure investment performance. The major findings of this research are as follows: First, the value strategy of buying value stocks and selling growth stocks were effective in the long-term investment. Second, using the moving average method, technical analysis were effective in the case of the short-term investment. Third, the portfolios combined fundamental analysis and technical analysis were more effective than investment performance of technical analysis.
