Purpose: This study was aimed to understand the meaning and essentials of the experience of burnout for hospital nurses with turnover intention. Methods: The design was a qualitative research of phenomenological study. Participants: Seven hospital nurses who had worked over three years and had experiences of turnover intention in a hospital with over 400 beds were included. Results: Nine meaningful themes related to burnout experiences and four theme clusters of 1) battery warning sounds almost out; 2) the player who hit the drum and double-headed drum; 3) the target flying arrow without a break; and 4) the pendulum swaying to turn over. Registered nurses (RNs) felt burnout with an overload of work and by the thought that it was illegal action for registered nurses to receive insufficient rewards for their work. RNs also experienced there were no problem solving strategies to verbal violence by patient and medical team. Conclusion: The findings show that burnout experiences for those who had turnover intention was developed from the insight that insufficient training to do work independently with over-load for nurses was not ethical. It suggests that it is necessary to rethink training systems for nursing and hospitals to relieve turnover intention.

It will be a real good news for the people who were lost their hometown by the construction of a large dam to be restored to the former state. Focused on Cheung-Pyung around where most part were flooded by the Chungju large Dam founded in early 1980s, we used Remote Sensing Technique in this study in order to restore topographical features before the flood with 3 dimensional effects. We gathered comparatively good satellite photos and remotely sensed digital images, then we made a new color image from these and the topographical map which had been made before the flood. This task was putting together two kinds of different timed images. And then, we generated DEM including the outskirts of that area as harmonizing current contour lines with the map. That could be a perfect 3D image of Cheung-Pyung around before when it had been flood by making perspective images from all directions, north, south, east and west, for showing there in three dimensions. Also, flying simulation we made for close visiting can bring us to experience their real space at that time.

This study tries to connect the 'four-elements metaphor' of Bachelard with architectural Images of Coop Himmelblau. Two basic terms of 'phenomenology of imagination' and 'material image' are explored firstly to understand the meaning and value of Bachelardienne four-elements in architectural discourse. The material images of air, fire, water, and clay are applied to the analysis of architectural experience of Busan Cinema Center(BCC) which is selected among works of Himmelblau by reason of its integrity of the four-elements' images. After elaborate Bachelardienne description of the images of BCC, the study examines whole Himmelblau's works since 1968 chronologically from the perspective of the four-elements' architectural images which are found in the analysis of BCC. The study of BCC could discover the images of air in two roofs, the images of fire in Double cone, the images of water in outdoor cinema, Dureraum square, flying brides, and the images of clay in Cinemountain and BIFF Hill. The chronological study found that Himmelblau had started their projects with the images of air in 1968 and tried the fire from 1978, and their regular examination of water and clay images had begun in mid 90's. After 2000, they could show a certain harmony of the four elements in their works.

In this paper, we develop an interface for aerial photograph platform which consists of a quadrotor and a gimbal using the human body and the head posture. As quadrotors have been widely adopted in many industries such as aerial photography, remote surveillance, and maintenance of infrastructures, the demand of aerial video and photograph has been increasing remarkably. Stick type remote controllers are widely used to control a quadrotor, but this method is not an intuitive way of controlling the aerial vehicle and the camera simultaneously. Therefore, a new interface which controls the serial photograph platform is presented. The presented interface uses the human head movement measured by head-mounted display as a reference for controlling the camera angle, and the human body posture measured from Kinect for controlling the attitude of the quadrotor. As the image captured by the camera is displayed on the head-mounted display simultaneously, the user can feel flying experience and intuitively control the quadrotor and the camera. Finally, the performance of the developed system shown to verify the effectiveness and superiority of the presented interface.

Sixth generation will exploit satellite, aerial, and terrestrial platforms jointly to improve radio access capability and unlock the support of on-demand edge cloud services in three-dimensional (3D) space, by incorporating mobile edge computing (MEC) functionalities on aerial platforms and low-orbit satellites. This will extend the MEC support to devices and network elements in the sky and forge a space-borne MEC, enabling intelligent, personalized, and distributed on-demand services. End users will experience the impression of being surrounded by a distributed computer, fulfilling their requests with apparently zero latency. In this paper, we consider an architecture that provides communication, computation, and caching (C3) services on demand, anytime, and everywhere in 3D space, integrating conventional ground (terrestrial) base stations and flying (non-terrestrial) nodes. Given the complexity of the overall network, the C3 resources and management of aerial devices need to be jointly orchestrated via artificial intelligence-based algorithms, exploiting virtualized network functions dynamically deployed in a distributed manner across terrestrial and non-terrestrial nodes.

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.

For a doctor, diagnosing a patient's heart disease is not easy. It takes the ability and experience with high flying hours to be able to accurately diagnose the type of patient's heart disease based on the existing factors in the patient. Several studies have been carried out to develop tools to identify types of heart disease in patients. However, most only focus on the results of patient answers and lab results, the rest use only echocardiography data or electrocardiogram results. This research was conducted to test how accurate the results of the classification of heart disease by using two medical data, namely echocardiography and electrocardiogram. Three treatments were applied to the two medical data and analyzed using the decision tree approach. The first treatment was to build a classification model for types of heart disease based on echocardiography and electrocardiogram data, the second treatment only used echocardiography data and the third treatment only used electrocardiogram data. The results showed that the classification of types of heart disease in the first treatment had a higher level of accuracy than the second and third treatments. The accuracy level for the first, second and third treatment were 78.95%, 73.69% and 50%, respectively. This shows that in order to diagnose the type of patient's heart disease, it is advisable to look at the records of both the patient's medical data (echocardiography and electrocardiogram) to get an accurate level of diagnosis results that can be accounted for.

Purpose - Consumers have memories of their past time that they have not experienced. So consumers want to experience the past time and get pleasure through historical contents such as movies or dramas. This is because the re-created the past time sets the identity of the consumers who live today, and in the process, it give consumers emotional comfort. Consumers do not remember and sympathize with all of their historical time. In general, consumers remember the time that their communities are proud of. As s result, historical content is seen as a hero, and through that, consumers can check their identity. Also consumers experience positive emotions such as self-esteem, gratitude and pride through identification with heroes. That is, through historical contents, consumers can identify themselves and replace the current negative emotions with positive ones. Therefore, this study presents narrative identity and historical nostalgia that can affect positive evaluation of historical contents and suggest the factors the can induce such effects. This study was conducted to explain what the consumption effect of historical content is from a marketing perspective and what constitutes a component of historical content as a factor driving this effect. Research design, data, and methodology - This study has developed a questionnaire with 8 Hypotheses. The Films ('Masquerade(2012)', 'Roaring Current(2014)', 'Assassination(2015)', 'The Age of Shadow(2016)') and dramas('Six Flying Dragon(2015-2016)', 'Mr. Sunshine(2018-2019)') were used as experimental contents. 268 college students participated in this empirical study, and structural equation model was used to verify hypotheses. Results - Frist, narrative identity affects positive evaluation of historical contents. Nostalgia affect positive evaluation of historical contents. and narrative identity affects positive response of historical nostalgia. Second, character act relevance, circumstance similarity, and character attractiveness have positive influence upon response of narrative identity. Lastly, empathy for story and vividness of representation have also positive influence upon response of historical nostalgia. Conclusion - This study contributes to the theoretical and managemental development of historical contents. This study shows that narrative identity and historical nostalgia are important for success of historical contents. In order for historical content to be successful, it must manage elements of character act relevance, circumstance similarity, and character attractiveness, empathy for story and vividness of representation.
