Generating a super-resolution meteological data by using a high-resolution deep neural network can provide precise research and useful real-life services. We propose a new technique of generating improved training data for super-resolution deep neural networks. To generate high-resolution meteorological data with domain specific knowledge, Lambert conformal conic projection and objective analysis were applied based on observation data and ERA5 reanalysis field data of specialized institutions. As a result, temperature and humidity analysis data based on domain specific knowledge showed improved RMSE by up to 42% and 46%, respectively. Next, a super-resolution generative adversarial network (SRGAN) which is one of the aritifial intelligence techniques was used to automate the manual data generation technique using damain specific techniques as described above. Experiments were conducted to generate high-resolution data with 1 km resolution from global model data with 10 km resolution. Finally, the results generated with SRGAN have a higher resoltuion than the global model input data, and showed a similar analysis pattern to the manually generated high-resolution analysis data, but also showed a smooth boundary.

This paper is a study on the implementation of MAM(Media Asset Management) to utilize UHD contents as high quality broadcast material. The implementation method of this paper is to separate MAM roles with content management functions and transmission workflow functions from workflow, metadata and system interface related work, which are divided into core MAM and MAM-Ex structure. Through the method proposed in this paper, we improved the content management method by applying the page menu method to the material metadata modification and applying the template method to the material structure API. In addition, the storage of UHD material and the configuration of the component server are pooled without any distinction of channels, thereby enhancing the security of UHD transmission assets by minimizing the movement of contents together with broadcasting material protection.

This study aimed at evaluating and developing 119 emergency medical technicians' prehospital care for non-traumatic cardiac arrest. Total 322 EMT in Chungnam province and Daejeon city filled out the self-administered questionnaire. The data were analyzed by SPSS 18.0 for descriptive statistics. Among the 322 EMT, 309 (97%) and 169(53%) always or almost performed CPR and AED for nontraumatic cardiac arrest patient, respectively. Among the advanced EMT and nurse, IV were sometimes or not performed at 94.7% and medication including epinephrine which commonly used for survival of cardiac arrest were treated just at 9.3 % (14 person). The reason they did not perform each procedure for airway management, AED or IV was lack of manpower, limit of time or joggle of ambulance and legal restrictions. In conclusion, to increase survival rate of non-traumatic cardiac arrest in out-of-hospital, it is necessary to increase manpower, legal protection of EMS, establishment of standard operating procedure, practice for improvement technique and use of medication for ACLS.

Junior colleges are higher education institutions that have played a major role in the economic development of Korea by providing the necessary human resources for its industrial development. Recently, however, they have experienced difficulties due to the reduction in the number of students. Therefore, it is time for junior colleges as a representative higher vocational education institution to change their role in this rapidly changing environment, and adopt a survival strategy through mutual cooperation and competition. The purpose of this study was to analyze the current state of the national health universities, to investigate the policy changes adopted by colleges and universities, and to utilize the results as data. This study analyzed the current status of health science colleges nationwide and investigated the policy changes as well as the directions presented to the colleges, in order to use the results as the basic data to promote the diversification of the class periods and degree programs. This study surveyed 636 professors from health sciences departments and industry workers from May 1 to May 30, 2017. 70.7% of the respondents supported the transition of the existing three-year systems of the health science departments to four-year systems. The reason for this is that it is possible to strengthen the field practice and personality education of the students by having a sufficient number of class periods, and to provide them with an equal educational background. The most anticipated effect of the transition to a four-year system is to improve the social status of medical personnel and to improve the educational environment of the colleges/universities. Moreover, the universities, associations of medical personnel and Ministry of Education are expected to play a leading role in the transition to the four-year system. Based on the results of this study, it was concluded that a more systematic and advanced vocational education system for the training of professional healthcare workers is needed in the upcoming fourth Industrial Revolution era. Also, this transition is expected to actively foster the education of advanced health care workers thanks to the diversification of the degree programs through the adjustment of the class periods which can be completed by general university (4-year) graduates.

Reflecting times, Korean TV dramas have gone through massive changes. So have their main characters. This study is about their jobs, which have become more professional as well as diverse. It is observed that the male characters" jobs and job-related episodes take the center stage in the stories of dramas, rather than love stories of those characters. While main characters' jobs used to be part of the overall backdrop in the past, it has been the latest trend for a drama to begin building conflicts around and in the meticulously described work settings. This is opening up the possibility for new categories of genre dramas, as opposed to the typical Koran melodramas. For further success of this newly burgeoning trend, the sense of reality matters the most. Then, it requires elaborately built narratives, based upon a high level of expertise of playwrights in the relevant fields, and realistic proper image processing techniques.

Recently, a computational reconstruction method using an integral imaging technique, which is a promise three-dimensional display technique, has been actively researched. This method is that 3-D images can be digitally reconstructed at the required output planes by superposition of all of the inversely enlarged elemental images by using a hypothetical pinhole array model. However, the conventional method mostly yields reconstructed images having a low-resolution, because there are some intensity irregularities with a grid structure at the reconstructed mage plane by using square-type elemental images. In this paper, to overcome this problem, we propose a novel computational integral imaging reconstruction (CIIR) method using round-type mapping model. Proposed CIIR method can overcome problems of non-uniformly reconstructed images caused from the conventional method and improve the resolution of 3-D images. To show the usefulness of the proposed method, both computational experiment and optical experiment are carried out and their results are presented.
