Gondola is widely used as a construction facility to perform external finishing work without using scaffolding at a construction site. However, since 2000, there have been 17 deaths from now so these risks associated with work can not be ignored. Therefore, it is expected that it will contribute greatly to prevent related disasters if introducing necessary measures to prevent repeated related disasters and installing additional safety devices. In order to eliminate the risk factor according to the operation of the gondola, it is necessary for the operator to use it to use it while the examination of each product is completed, and to use the over load Dangerous arbitrary measures such as arbitrary operation of the prevention device, removal of the safety fence for convenience of work, installation of the wire rope installed in the air, falling out of the wire rope and falling to the ground Do not perform such sealing measures so that any operation of the overload prevention device can not be done so as not to take such arbitrary measures, or wire the power supply wire to the safety fence so as not to delete the safety fence. Then, when the safety fence is removed, so that it does not become a gondola operation, or when replacing the wire rope in the air, to prevent the wire rope from coming off, Additional measures such as installing falling down prevention device may be necessary.

It has been only a few years since drones have been introduced to Korea, and as the use of drones has increased in industrial sites as well as in hobby activities, accidents such as workers' body parts coming into contact with rotating propellers have been occurring since 2016. Industrial accident cases are being filed. In the case of a remote control vehicle, if you release the remote controller in the event of an abnormal situation, it stops in place and no further danger occurs but in case of drones flying over the sky is different. Sudden motor stops during flight, uncontrolled changes in flight posture, loss of radio waves, loose propeller, etc, numerous factors can lead to accidents due to unintentional movements. Therefore, drone operators need safety knowledge as well as high knowledge about drones. However, drones with a weight of less than 12 kg can fly without a pilot's certification, and therefore, a minimum accident prevention measure is required. 10 accidents approved as industrial accidents since 2016, 23 accidents surveyed by general drone operator, 40 accidents surveyed by the Korean Consumer Resources Unfortunately for the purpose of writing this paper, drones are a new species and do not have many parameters for analysis but my experience has shown that the type of disaster does not deviate significantly. In addition, there is no paper that analyzes drone related industrial accidents not only in Korea but also in other countries. However, even if you watch an overseas drone accident video through YouTube, it is not much different from the case that occurs in Korea. I hope that this study will be of little help to all the drone pilots as well as the work safety of industrial drones used in industrial sites.

Objective : Interaction of warfarin with herbal medicines still remains controversial. The aim of this study was to examine the effect of herbal medicines which contain ginseng on PT INR in patients being treated with warfarin. Method : We studied patients who take herbal medicines which contain ginseng with warfarin during their hospitalization. We retrospectively investigated the effect of herbal medicines which contain ginseng. 10 patients were assigned to receive one of the following adjuncts: Group A (n=4) that received Bojungikkitang-gagam, Group B (n=2) that received Ukgunjatang-gagam, and Group C (n=4) that received Shihogyeji-tang, Gamiondam-tang, Gwininaanshim-tang, and Saengpe-san together. We then investigated changes of PT INR in each group. Result : In group A, there were diminutions of PT INR in 3 cases, and increment in 1 case. In group B, there were increments of PT INR in both cases. In group C, there were increments of PT INR in 3 cases and there was no big change in 1 case. Conclusion : In this study, we found that the interaction of combined herbal medicine is very complicated. So, we must study further more study about interactions of combined herbal medicine on PT INR.

Bojungiki-tang is a traditional oriental medicine to boost the immune system. In this study, we investigated the effects of Bojungiki-tang by withdrawal of isolation of VRE colonization. Four cases of post-stroke patients with VRE colonization took Bojungiki-tang and continuously were followed up with stool cultures. After three times negative stool VRE, we withdrew isolation of VRE colonization. One case patient was diagnosed with VRE colonization in another hospital and had no withdrawal during that period. He was admitted to Kyung-hee University Oriental Medicine where he took Bojungiki-tang. After three times negative stool VRE, we withdrew isolation of the patient. These results demonstrate that Bojungiki-tang is effective on boosting immunity level. Further studies are needed to better characterize this protective effect of Bojungiki-tang.
