The use of smart phones has had a great impact on the mobile internet business. It shows a lot of growth in the healthcare sector not only commerce, advertising, billing, games, video content, media, amd O2O business. The United States has eased the regulations for healthcare apps smart phone devices in 2015, and China has established a five-year road map to solve shortage of doctors and hospital beds by utilizing mobile devices such as wearable in the same year. The application of wearable devices in the medical field is gradually increasing in Korea too, but there is a security problem as leading challenge. Security incidents in non-ICT sectors such as financial, medical, etc. have increased by using ICT each year. Personal information leakage is also increasing in field likely occurring the potential secondary damages such as financial fraud, illegal promotions, insurance and pharmaceutical companies abuse. In this study, we analyze malwares as the mobile threats, the five risks of mobile smart phone, mobile use cases and the mobile threat countermeasures for healthcare.

In this paper a method of reconstructing a desired image through the geometrical transformation and the interpolation techniques is presented by comparing different interpolation schemes. Several different interpolation schemes are compared with respect to the amount of error that is the difference between the original and the reverse-projective transformed images. Higher ordered B-spline interpolation turned to be superior to other techniques in reconstructing the image which is desired to be close to the unskewed image as much as possible. In the results, this paper demonstrates that the reverse projection using the higher ordered B-spline interpolation is superior to those conventional interpolation methods, linear, cubic spline for reconstructing image. In experiments, the error decreases as the order of B-spline increases. The proposed technique is useful for various practical and theoretical applications in the area of satellite, medical, and commercial image processing.

The purpose of the study was to identify the untact medical services campaign awareness in COVID-19 era using Q methodology. We used subjective analysis for this purpose and examined 1) what are the types of untact medical services campaign awareness? and 2) what are the homogeneous characteristics and implications between each type? We composed a Q concourse through interviews with university students to write Q statements, selected a P sample, and used Q-sort obtained from the sorting process to analyze it through Q-factor analysis in the PC QUANL program. Q methodology was used to examine the subjective tendency of untact medical services campaign awareness in COVID-19 era. As a result of the analysis, four types were identified. 1) Type 1 (N=7): Belief & official announcement type, 2) Type 2 (N=4): Governmental notice type, 3) Type 3 (N=3): Medical information public notice type, 4) Type 4 (N=2): Sympathetic information type. An insightful analysis was derived in that the analysis could identify factors in the schema of respondents related to untact medical services in COVID-19 era.

Mobile communication technology was one of the GPS technology, SmartPhone, Tablet PC is equipped with a GPS. So the user has a navigation, speed and his position to send and receive a variety of information. Therefore, in this paper, Mobile devices, GPS, Wi-Fi and mobile networks, and the communication module uses algorithms to analysis of acceleration and output, the user is currently using the system to find out the kind of transportation. This is the users who are using a particular transport unnecessary information and apply it to different areas do not think I will be able to.

Eye tracking is one of the NUI technologies, and it finds out where the user is gazing. This technology allows users to input text or control GUI, and further analyzes the user's gaze so that it can be applied to commercial advertisements. In the eye tracking system, the allowable range varies depending on the quality of the image and the degree of freedom of movement of the user. Therefore, there is a need for a method of estimating the accuracy of eye tracking in advance. The accuracy of eye tracking is greatly affected by how the eye tracking algorithm is implemented in addition to hardware variables. Accordingly, in this paper, we propose a method to estimate how many degrees of gaze changes when the pupil center moves by one pixel by estimating the maximum possible movement distance of the pupil center in the image.

The most important property for coming up to the global change and leading the knowledge-based future is human resources who has capacity to make a high value-added knowledge. For whom teaching knowledge and experiences related to the managing medical organization, it is very important and significant to make efforts to reflect educational goal, contents and teaching methods satisfying the new era's demands in the curriculum quickly. To develop a hospital management curriculum which is receptive to the change of medical industry and educational circumstances, analysing syllabuses of 19 departments of the year 2007 and surveying of professors, students and persons in charges of hospital administration are used. The syllabuses of 19 departments of 22 colleges were opened for this study. The medical record and other subjects take the most part of curriculums, while the number of subjects related to management or administrational practice are relatively small. The short of these subjects are obstacles to cultivate capacity and quality of students medical organizations look for. As the result of satisfaction measurement, hospital-management professors gave 3.41 points, students gave 3.29 points to the current curriculum and administrators who has been experienced to employ graduates majored in medical management gave 3.06 points.(5 points = full mark) Alternative ways are suggested to complement these problems as below: Strengthening and deepening study such subjects as strategy planning, management, marketing, managing medical disputes, quality improvement, PR, advertisement; changing informations and establishing cooperative programs between school and industry.

In these days, image mosaic is getting interest in the field of advertisement, tourism, game, medical imaging, and so on with the development of internet technology and the performance of personal computers. The main problem of mage mosaic is searching corresponding points correctly in the overlapped area between images. However, previous methods requires a lot of CPU times and data processing for finding corresponding points. And they need repeated recording with a revolution of 360 degree around objects or background. This paper presents a new image mosaic method which generates a panorama image from a video sequence recorded by a general video camera. Our method finds the corresponding points between two successive images by using a new direction oriented 3­step block matching methods. Experimental results show that the suggested method is more efficient than the methods based on existing block matching algorithm, such as full search and K­step search algorithm.

Backgrounds: Proper distribution and supply of physicians are factors that affect national health care systems. This study investigated the payment distribution levels and the determinants that influence the salary levels of hospital hired physicians. Methods: We analyzed 4,014 job advertisements posted on an internet invitation information site about physician recruitment from May 2016 to May 2019. We used univariate analysis to determine the relationship between average monthly salary and the other related variables. Multiple regression analysis was used to determine the predictors of physician salary level. Results: The average monthly salary for the service physician was 15.4 million won, highest for orthopedic surgeons with 22.24 million won, and lowest for diagnostic laboratory physician with 11.4 million won. The factors significantly associated with average monthly salary were; non-major specialty, housing provision, no severance pay, and incentives(p<0.05). Non-major specialty, incentives, and the regions were predictors of the average standardized monthly salary(p<0.05). Conclusion: Factors associated with average monthly salary as revealed by this study were; medical specialty, hospital regional location, housing provision, payment of retirement allowance, and payment of other incentives respectively. However, this study was a cross-sectional study, and further studies will be required.
