Objectives : While there are many studies about treatments of facial palsy, no study has been performed on general population of Korea, especially concerning about comparison between western medicine and oriental medicine. This study aimed to investigate magnitude of health visits and treatment patterns for Korean patients with facial palsy through the computerized database of Health Insurance Review and Assessment Service(HIRAS). Methods : According to the HIRAS database over 5 years' period from 2004 to 2008, the medical records of patients with facial palsy as a main diagnosis were extracted. Inclusion criteria of facial palsy are Bell's palsy(G510), Geniculate ganglionitis(G511), Melkersson's syndrome(G512), Other disorders of facial nerve(G518), Disorder of facial nerve, unspecified(G519) in western medicine. And Paralytic face(G016), Deviated eye and mouth(J01), The other facial palsy(J013) were included in oriental medicine. We compared the claim number of western medical care with that of oriental medicine treatment by year and month. Results : The total claim number of facial palsy was increasing on both western medicine and oriental medicine from 2004 to 2008. In western medicine, the claim number of Bell's palsy(G510) is the most. In oriental medicine the inpatients claim number of Deviated eye and mouth(J01) is the most, while outpatients claim number of the other facial palsy(J013) is the most. Conclusions : Medical database of HIRAS provided comprehensive and vast information on epidemiologic characteristics and treatment, which can be more reliable data to expect medical demand for facial palsy in condition that accurate diagnosis and standardized treatment is delivered in clinical settings.

In an effort to compensate the rising of the data throughput demand nowadays, there have been many research works to optimize the radio resource and increase the capacity of the network. At the present, small cell network, mmWave band and beamforming technology are leading the trend and becoming the core solutions of the fifth generation (5G) cellular networks. Since the propagation characteristics of radio wave in the mmWave band is quite different from the conventional bands, the communication systems which work in these bands have to be redesigned. In this paper, a 3D simulation model is discussed for cellular network at 60 GHz in outdoor environments. Coverage analysis and system performance is carried out for a small cell system in the typical urban environment including street canyon simulation scenario. In addition, the beamforming technique is considered to evaluate the throughput improvement. Simulation results show that the mmWave small cell systems is expected to be one of the major candidate technologies to satisfy the requirements of 5G in terms of data rate.

This study was performed to determine the job satisfaction and its association with sociodemographic and health related characteristics, job-related factors and job stress among nursing officers. The survey was administered to 350 nursing officers working at military hospitals of the ROK Armed Forces, from May 30 to June 15. The structured self-administered questionnaires were delivered and they were collected without respondents' personal information. As a results, The job satisfaction of respondents turned out to be significantly higher in the group of elder, current drunker, higher positional status, a longer job career, department of general wards, satisfied with their work, fit to the job, haven't considered quitting the job, lower job demand, higher decision latitude and higher support from supervisor. Especially, job stress is highly correlated with job satisfaction. Therefore, to initiate inner motives leading to higher job satisfaction to provide a better working environment for nursing officers, serious effort is necessary to improve the factors related with job stress.

We are exposed to video content and numerous information from digital signage such as convenience stores, coffee shops, restaurants, and elevators on buses and subways 365 days. However, so far, studies have focused solely on the technical effectiveness of digital signage or the consumer experience aspect of digital signage, and little has been done on the impact of teaser advertising on the intent of viewing. Through this study, we hope that the digital signage of convenience stores will develop into a differentiated digital signage area that provides diverse video content experiences to consumers and viewers and allows them to communicate, suggesting a direction as a research that shows that digital content (video) is now recognized as a product in an environment where demand for non-face-to-face and digital content is gradually increasing in 2020 after the global COVID 19.

In recent years, owing to the growing user demand for the two-way internet service based on the mobile global broadband communications, a new type of satellite terminal has been developed, known as ESIM(Earth Station in Motion). This service was required by Resolution 158(WRC-15) to study on the coexistence with the co-primary FS(Fixed Service) in 27.5-29.5 GHz as a FSS(Fixed Satellite Service) uplink. In this paper, the average received power on ESIM within -10 dB of beam width of FS and its outage probability was analyzed theoretically and also simulated to account for the azimuth angle with uniform distribution. From the results, it can be concluded that this theoretical analysis is very useful to analyze the interference from ESIM into FS based on the statistical and probabilistic method. Therefore, it is necessary to control the azimuth angle due to a moving terminal as well as the inclination angle of moving path, the operation hours, and the speed of ESIM to protect the co-primary FS.

Recently, there is increasing demand for image processing technology while activated the use of equipments such as camera, camcorder and CCTV. In particular, research and development related to 3D image technology using the depth camera such as Kinect sensor has been more activated. Kinect sensor is a high-performance camera that can acquire a 3D human skeleton structure via a RGB, skeleton and depth image in real-time frame-by-frame. In this paper, we develop a system. This system captures the motion of a 3D human skeleton structure using the Kinect sensor. And this system can be stored by selecting the motion file format as trc and bvh that is used for general purposes. The system also has a function that converts TRC motion captured format file into BVH format. Finally, this paper confirms visually through the motion capture data viewer that motion data captured using the Kinect sensor is captured correctly.

Especially in Korea, LNG terminals commonly have huge scale because of the high demand of natural gas, and for the safe operation of terminal wide observation on temperature is necessary. That is the reason why the terminal has thermometer all over the facility but another information, flow rate, is insufficient. By the way, in pipeline, temperature difference is highly related with flow rate and with some simple assumptions, we can estimate flow rate. And through the steady state data reconciliation, the flow rate data become more reliable. In this research, we will study about flow rate data reconciliation method for LNG terminal and case study.

With the recent rapid development of deep learning technology, the demand for analyzing huge text documents in the national R&D field from various perspectives is rapidly increasing. In particular, interest in the application of a BERT(Bidirectional Encoder Representations from Transformers) language model that has pre-trained a large corpus is growing. However, the terminology used frequently in highly specialized fields such as national R&D are often not sufficiently learned in basic BERT. This is pointed out as a limitation of understanding documents in specialized fields through BERT. Therefore, this study proposes a method to build an R&D KoBERT language model that transfers national R&D field knowledge to basic BERT using further pre-training. In addition, in order to evaluate the performance of the proposed model, we performed classification analysis on about 116,000 R&D reports in the health care and information and communication fields. Experimental results showed that our proposed model showed higher performance in terms of accuracy compared to the pure KoBERT model.
