A smart home system improves the elderly's quality of life by monitoring and analyzing their movements and health conditions with better health-care and social support services. Therefore, there has been an effort to adopt a smart home system for the independently living elderly. However, to the best of our knowledge, no study has investigated the usability of a smart home system on actual independently living elderly housing in long-term settings. Thus, this study aims to demonstrate the usability of a smart home system on independently living elders in living lab conditions. The BLE smart band and the BLE receiver were chosen for the smart home system to monitor the movement of the participants in their homes as well as to monitor the heart rates, step counts, sleep index. Nine independent living elderly from the senior welfare center in Kimjae participated in this living lab demonstration experiment for ten months. This demonstration experiment confirmed the effectiveness of low-cost and easily adoptable IoT-based BLE sensor sets on independent living elders and discussed the troubles and limitations of the experiment. By grasping the pros and cons of IoT-based BLE sensor sets, this study seeks to improve the accessibility and usability of smart home systems for the elderly population in independent living arrangements.

With proliferation of the internet, the internet ethics in contrast to existing ethics has been recognized as one of the disciplines. Internet ethics is one of liberal arts courses in a college as well as a class in elementary, middle and high schools. We also have taught this subject for a number of years. In order to effectively communicate to students the internet ethics course as computer scientists, we gave some demonstration practice lectures by taking advantage of internet ethics related videos. Since the latest UCC presentation and its discussion were performed, it was helpful for students to recognize the internet ethical issues and concerns. We confirmed that classroom students' concentration and understanding for internet ethics increases by a survey of the regular attendees. This research presented a lecture practice case model to teach comprehensive internet ethics topics to college students effectively.

To manage the non-point source pollution and restore the water circulation, many technologies including infiltration or reservoir systems were installed in the urban area. These facilities have many problems regarding maintenance as their operation period becomes lengthier. The purpose of this study was to estimate the optimal maintenance timing through a long-term load test on the infiltration trench as one of the low impact development techniques. An infiltration trench was installed in the demonstration test facility, and stormwater was manufactured by Manual on installation and operation of non-point pollution management facilities from the Ministry of Environment, Korea and entered into the infiltration trench. Particle size distribution (PSD), suspended solids (SS) removal efficiency, and infiltration rate change tests were performed on inflow and outflow water. In case of the PSD, the maximum particulate size in the outflow decreased from 64 ㎛ to 33 ㎛ as the operating duration elapsed. The SS removal efficiency improved from 97 % to 99 %. The infiltration rate changed from 0.113 L/sec to 0.015 L/sec during the operation duration. The maintenance timing was determined based on the stormwater runoff requirements with these changes in water quality and infiltration rate. The methodologies in this study could be used to estimate the timing of maintenance of other low impact development techniques.

It is very important to set a reliability target and verify the requirement when procuring the rolling stock in the aspect of safety, availability and LCC. While there are a few different methods to verify the reliability target, it is required that the most appropriate method should be used considering the characteristics of rolling stock itself and the operation environment. Even though recently the quantitative reliability requirements are widely adopted in domestic market, there is no substantial contents in the various standards and guidelines. In this study we investigate the various reliability demonstration test plans and evaluate them for rolling stock application. And three test plans among them were applied to the real operation data.

This study investigated and summarized the history of peasant movement which had been done by various peasant associations Yesan, Hongsong, and Tangjin from the beginning of Korean Catholic Peasant Movement from 1970 to 1995. First of all, we classified all the peasant movements(Yesan ; 120 times, Hongsong; 113 times and Tangjin; 107 times / total; 340 times) into 5 categories composed of movement time, movement type, movement method, the number of participators, and the movement subjects(issues). The frequency of peasant movement from 1990 to 1995, occupied 65.6%, which shows that the peasant movement was the most active during the time. The frequency of movement type, were we could find out, self-dependence type(62.9%), resistance type(15.6%) and request type(21.5%). The active way like congregation, demonstration, sit-in, rice file up struggle occupied 28.8% and it got the first place in movement way. In the movement subject category, the construction of organizations and solidarity activity amounted to 37.8% and democratization item(the union democratization and the social democratization related peasant) covered 16.8%. The 98 times of peasant movement were done in the active ways such as congregation and demonstration. However we cannot find these active ways in 1970s. In 1980s, the frequency of each item (congregation, demonstration, publicity and propaganda) was 28 times. But in 1990s, the frequency of congregation, or demonstration was higher than the others. The number of participators in peasant movement increased during 1980s∼1990s. The movement of which participators were 100∼499 was 32 times in 1980s and 70 times in 1990s each time. Such large scale movement amounted to over 30%. Furthermore, the large scale movement in which over 500 people participated amounted to 12 times in 1990s.

The purpose of this study was to analyze the learning effects of video demonstration in a multitude of video screens in a science class. To examine this, an experiment from the first year science textbook was chosen, which looked at the relationship between electrical voltage and electrical current. Three experimental groups were used for the purpose of this study: 1/ a control group which used experimental still photos during a traditional class. 2/ experimental group A which used videos in a single screen, and 3/ experimental group B which used a multitude of video screens to demonstrate their effects. Post test learning effects was then carried out on each group related to the units. The results showed an improvement in grade for all groups. Experimental group B showed the most significant result, followed by the experimental group A. The control group showed the least significant grade improvement. In conclusion, the study revealed that the utilization of video demonstration in a science class is very useful and can be adapted in different forms in class. To enhance the effects of the learning method in conveying efficient meaning, versatile methods should be used to stimulate and heighten students' interests by mixing still photographs and video demonstration with various screen composition with the help of information technology.
