The senior citizens who ever received oral health education had a better knowledge(p<0.05) and took a better attitude(p<0.01). 3. As for a time for toothbrushing, many brushed their teeth after breakfast(74.9%) and dinner(71.8%). Utilized Oral hygiene devices were interdental brushes(21.5%), dental floss(13.8%).

The rate of regular scaling was higher in the elderly groups that ever received oral health education and whose knowledge scores was above the average(p<0.05). 5. In relation to the necessity of oral health education, 87.2% felt the need for that, and as many as 79.0% intended to receive that education. Their favorite period of education was 6months(41.0%), and the greatest group hoped to receive that education for an hour(55.4%). The largest group wanted to learn about prevention of oral diseases, followed by toothbrushing, denture management, dry mouth.

Unmanned Aerial Vehicles (UAV) have mostly been used for military purposes but with the progress in ICT and reduced manufacturing costs, they are increasingly used for various private services. UAVs are expected to carry out autonomous flying in the future. In order to carry out complex tasks, swarm flights are essential. Although the swarm flights has been researched a lot due to its different network and infrastructure from the existing UAV system, There are still not enough study on security threats and requirements for the secure swarm flights. In this paper, to solve these problems, UAV autonomous flight technology is defined based on US Army Corps of Engineers (USACE) and Air Force Research Laboratory (AFRL), and swarm flights and security threat about it are classified. And then we defined and compared security requirements according to security threats of each swarm flights so as to contribute to the development of secure UAC swarm flights in the future.

The purpose of this study was to investigate the association of homocysteine and antioxidant nutrients with obesity in Korean middle aged women. The study subjects included were middle-aged obese women (n=36) whose body mass index (BMI) was greater than $25kg/m^2$. A total of 36 participants were randomly divided into two groups. They were assigned to either the Nutritional Management and Exercise (NME) program or the Exercise Management (EM) program, which were both conducted for 3 months. We measured serum homocysteine, total cholesterol and HDL cholesterol levels of the participant. We also measured the dietary intakes of antioxidant nutrient, cholesterol, body weight, body mass index, blood pressure, and $VO_2$. At the end of both programs, please confirm this change. It was unclear when these measurements were shown to have decreased. The body weight and BMI of NME group were decreased compared to those of EM group. The serum total cholesterol levels of the participants in NME group were significantly decreased, in contrast to EM group. Also, serum homocysteine levels of NME group participants were decreased compared to EM group, but the difference was not statistically significant. In the NME group, there were significant differences in the change of dietary cholesterol and vitamin C intake. These results showed that participating NME program will continuously promote the healthy status of the middle aged obese women, compared to participating only in the EM program.

According to the change in media environment, a support plan for local broadcast has been required. In terms of legal and institutional support for the development of local broadcast, the enactment of special Act for local broadcast has become a breakthrough. In this point of view, we analyzed the performance and the limitation of the special Act. As a literature research, analyzing the literature and related-ordinances, we have sought legal and institutional support plans for the local broadcast. As a result, with the Local Broadcast Development Council being in charge of legislative right and responsibility, a plan to empower them to have legal and institutional authority should be drawn; another plan to secure independence in operating a fund and to promote the capability to produce local broadcast programs and the distribution system should be drawn; the other elaborate plan for the locality index that assesses the locality is required. Local broadcast should be on a way to secure not only public interest and concern but locality and diversity; legal and institutional plans should be sought.
