This paper aims to look at the perspective that the latest cutting-edge technologies are predicting individual diseases in the actual medical environment in a situation where various types of wearable devices are rapidly increasing and used in the healthcare domain. Through the process of collecting, processing, and transmitting data by merging clinical data, genetic data, and life log data through a user-participating wearable device, it presents the process of connecting the learning model and the feedback model in the environment of the Deep Neural Network. In the case of the actual field that has undergone clinical trial procedures of medical IT occurring in such a high-tech medical field, the effect of a specific gene caused by metabolic syndrome on the disease is measured, and clinical information and life log data are merged to process different heterogeneous data. That is, it proves the objective suitability and certainty of the deep neural network of heterogeneous data, and through this, the performance evaluation according to the noise in the actual deep learning environment is performed. In the case of the automatic encoder, we proved that the accuracy and predicted value varying per 1,000 EPOCH are linearly changed several times with the increasing value of the variable.

The purpose of the study was to present basic data to evaluation of the spatial resolution for exposure class(EC) in computed radiography(CR) by using the modulation transfer function(MTF). In this study, MTF was measured the edge method by using image plate(IP) of $100{\mu}mm$ pixels. A standard beam quality RQA5 based on an international electro-technical commission(IEC) standard was used to perform the X-ray imaging studies. Digital imaging began to set the sensitivity to EC 50, 100, 200, 300, 400, 600, 800, 1200 in X-ray irradiated to IP. The MTF 50% and 10% in the final images was analysis by using an authorized image analysis program the Origin 8.0 and the image J. As a results, the EC 200 was the best spatial resolution at MTF 50% ($1.979{\pm}0.114lp/mm$) and MTF 10% ($3.932{\pm}0.041$). Therefore, the EC 200 could be useful for the diagnosis of diseases that require high spatial resolution such as fractures.

This study studied scoliosis, one of the most common modern diseases caused by lifestyle patterns of office workers sitting in front of computers all day and modern people who use smart phones frequently. Scoliosis is a typical complication that takes more than 80% of the nation's total population at least once. X-ray are used to test for these complications. X-ray, a non-destructive testing method that allows scoliosis to be easily performed and filmed in various areas such as the chest, abdomen and bone without contrast agents or other instruments. We uses NI DAQ to miniaturize digital X-ray imaging devices and image intensifier in self-shielding housing with Vision Assistant for drawing lines to the top and the bottom of the spine to acquire angles, i.e. curvature in real-time. In this way, the research was conducted to see scoliosis patients and their condition easily and to help rapid treatment for solving the problem of posture correction in modern people.

The purpose of this study was to analyze the characteristics of elderly motorcycle accidents according to data from elderly inpatients to prepare prevention measures for the elderly against injury in motorcycle accidents. Chi-squared test, independent sample t-test, and canonical correlation analysis were performed on the Korea Disease Control and Prevention Agency's National Hospital Discharge In-depth Injury Survey data from 2015 to 2019, from which the records of 1,384 elderly inpatients hospitalized because of motorcycle accidents were obtained. intracranial injury(S06) was the most common care and treatment characteristic for both age groups. The most frequent injury site was the head and neck, and the most frequent injury type was a fracture. The above findings show that prevention education and policy formulation at the national level are necessary to identify and manage the factors of elderly motorcycle accidents. This study provides basic data for developing measures and policies to prevent and reduce injuries, making it significant for public health causes.

각종 음성질환에 있어서 음성검사는 진단뿐 아니라 치료를 위한 중요한 방법으로 알려져 왔다. 특히 수술전후 음성질환의 평가에는 음성검사 뿐 아니라, 후두스트로보스코피를 이용하여 비교함으로써 가능하다. 이중 후두스트로보스코피는 방법이 간단하여 직접 수술전후의 변화를 알 수 있는 장점이 있으나, 객관적인 자료로는 이용하기가 어려운 문제점이 있다. 후두스트로보스코피의 영상자료를 컴퓨터에 연결, 영상신호를 디지털화하여 후두의 움직임을 객관적으로 관찰하려고 시도되어왔다 특히 편측 성대마비 환자에서는 성대의 위치가 외전 될뿐만 아니라 피열연골의 위치가 마비 후 시간이 경과됨에 따라 외회전 하고 성대가 전방으로 위축되어 성대 막성부의 길이가 짧아지는 틀의 후두스트로보스코피의 영상을 보이고, 성대폴립환자에서는 수술전후에 폴립의 크기와 성문면적에 변화를 보이게 된다. 본 연구의 목적은 편측 성대마비와 성대폴립과 같은 각기 다른 두 질병에서 음성경사와 후두스트로보스코피를 이용한 이미지 화상분석을 통해 각 성대의 길이, 각도, 성문틈의 면적과 폴립의 크기등을 측정함으로써 수술전후의 차이를 알아보고, 이미지 화상분석과 음성검사 사이에 어떠한 상관관계가 있는지를 알아보고자 하였다.

골다공증은 해면골의 골소주 두께 감소 및 파단에 기인한 전체적인 골질이 저하되는 질병이다. 골다공증을 예방과 조기진단을 하기 위해서는 골밀도를 측정하여야 한다. 보다 나은 이미지를 얻기 위해 Digital X-Ray로 골밀도를 측정하여 영상 처리하기 위한 방법을 제시한다. 먼저 디지털 센서에서 증감지와 렌즈간 거리가 가까워서 증감지의 중심과 주변부의 광 경로차이가 발생하므로 왜곡이 발생하는데 이를 균일화하여야 한다. 그리고 X-Ray장비의 조건에 따라 영상에 많은 차이를 보이므로 영상의 밝기를 보정하는 과정이 필수적이다.

본 연구는 코로나-19 이후로 미지의 질병과 맞닥뜨렸을 때의 소비 경향에 중요한 영향을 끼치는 요소를 데이터베이스화하여 다각적인 방면에서 분석하고 성향 측정방법을 제시하였다. 포스트 코로나 시대는 디지털 혁명이 일어난 후 경제활동에 참여하고 있는 사람들 중 그 누구도 피해갈 수 없는 흐름이다. 또한, 소비의 흐름에 있어서 모바일을 통한 배달이 주류가 될 것이라는 것은 누구든 손쉽게 알 수 있을 것이다. 후에 제2의 포스트 코로나 이후 방대하고 구체적인 데이터를 사용하여 똑같은 방법으로 재분석 한다면 기업의 입장에서 발 빠른 대응으로 경제 침체 속의 호황을 맞이할 수 있을 것이라 기대된다.

With the COVID-19 pandemic being prolonged, the society is being converted into an untact society, thereby affecting the service methodology of domestic and foreign library systems. This study thus surveyed the librarians' awareness of COVID-19 response measures of public libraries, and proposed public libraries' response measures in situations where the novel infectious disease is spreading and prolonging. Specifically, the proposed measures include, first, preparing national-centered library countermeasures to jointly respond to the epidemic disease, second, strengthening various untact and online services of various public libraries through government-level budget support, third, a thorough prevention of epidemics and preemptive response from the viewpoint of employees and users, and fourth, the expansion of library services aimed at resolving the digital cultural divide among classes of people, including information unfairness.

It is recognized universally that international cultural exchanges have the potential to weaken ethnic rivalries and conflicts and promote cultural diversity rather than commercial interests. However, there are often cases in which these exchanges are transformed into private businesses with a great success in markets due to changes in cultural consumption patterns. This research aims to analyze the performance of international cultural exchanges and to develop a policy model that can guide the overseas market performance for Korean traditional performing arts. This study analyzes domestic and foreign cases for comparison. The domestic case is drawn from the research report published by Korea Arts Management Service and the foreign case is Ireland's Riverdance. The results of this study indicate that the policy political model in which a traditional culture may be translated globally with innovative performing activities has the potential to raise market performance overseas.
