본 연구는 실업의 장기화, 장애차별현상 등 장애인노동시장 문제의 해법을 모색하기 위해 장애차별변수를 활용하여 장애인의 실업탈출과 이와 관련된 요인을 살펴보고자 하였다. 이를 위해 장애인고용패널조사의 3차~5차의 자료를 활용하여 자료를 구성하고 실업탈출(취업)과 관련하여 사건사 분석을 실시하였다. 분석결과는 다음과 같다. 첫째, 실업기간에 따른 실업탈출가능성의 변화를 생명표 분석을 통해 분석한 결과, 최장 실업기간(25개월)까지 실업상태로 남아 있는 비율은 90.5%이고, 노동시장에 진입한 비율은 9.5%에 불과한 것으로 나타났다. 전반적으로 실업유지율은 매우 높게 나타났고, 실업탈출 가능성은 12개월까지 증가하다가 그 이후부터는 감소하는 추세를 보이는 것으로 나타났다. 둘째, 실업탈출에 영향을 요인을 파악하고자 콕스비례해저드모형을 이용하여 분석한 결과, 남성일수록, 비수급가구일수록, 경증일수록, 직장차별경험이 없을수록 실업탈출 가능성이 높아지는 것으로 나타났다. 이러한 결과를 통해 장애인의 실업탈출(취업)을 촉진하기 위해서는 우선 고용상에 발생하는 장애차별을 해소할 수 있는 장애인차별금지제도를 보다 강화해야 하며, 기초수급 장애인들의 근로를 유인할 수 있도록 현행 국민기초생활보장제도를 보완할 필요성이 있음을 제안하였다. 추가적으로 실업탈출에 어려움이 있는 여성장애인, 중증장애인 등과 같이 정책대상을 보다 세분화하여 개별욕구와 특성에 부합하는 고용서비스의 필요성을 제안하였다.

Background: Breast cancer risk prediction models are widely used in clinical practice. They should be useful in identifying high risk women for screening in limited-resource countries. However, previous models showed poor performance in derived and validated settings. Therefore, we aimed to develop and validate a breast cancer risk prediction model for Thai women. Materials and Methods: This cross-sectional study consisted of derived and validation phases. Data collected at Ramathibodi and other two hospitals were used for deriving and externally validating models, respectively. Multiple logistic regression was applied to construct the model. Calibration and discrimination performances were assessed using the observed/expected ratio and concordance statistic (C-statistic), respectively. A bootstrap with 200 repetitions was applied for internal validation. Results: Age, menopausal status, body mass index, and use of oral contraceptives were significantly associated with breast cancer and were included in the model. Observed/expected ratio and C-statistic were 1.00 (95% CI: 0.82, 1.21) and 0.651 (95% CI: 0.595, 0.707), respectively. Internal validation showed good performance with a bias of 0.010 (95% CI: 0.002, 0.018) and C-statistic of 0.646(95% CI: 0.642, 0.650). The observed/expected ratio and C-statistic from external validation were 0.97 (95% CI: 0.68, 1.35) and 0.609 (95% CI: 0.511, 0.706), respectively. Risk scores were created and was stratified as low (0-0.86), low-intermediate (0.87-1.14), intermediate-high (1.15-1.52), and high-risk (1.53-3.40) groups. Conclusions: A Thai breast cancer risk prediction model was created with good calibration and fair discrimination performance. Risk stratification should aid to prioritize high risk women to receive an organized breast cancer screening program in Thailand and other limited-resource countries.

The purpose of this study is to design and build fake news discrimination systems and methods using fact-checking guidelines. In other words, the main content of this study is the system for identifying fake news using Artificial Intelligence -based Fact-checking guidelines. Specifically planned guidelines are needed to determine fake news that is prevalent these days, and the purpose of these guidelines is fact-checking. Identifying fake news immediately after seeing a huge amount of news is inefficient in handling and ineffective in handling. For this reason, we would like to design a fake news identification system using the fact-checking guidelines to create guidelines based on pattern analysis against fake news and real news data. The model will monitor the fact-checking guideline model modeled to determine the Fact-checking target within the news article and news articles shared on social networking service sites. Through this, the model is reflected in the fact-checking guideline model by analyzing news monitoring devices that select suspicious news articles based on their user responses. The core of this research model is a fake news identification device that determines the authenticity of this suspected news article. So, we propose news article identification methods with fact-checking guideline on Artificial Intelligence & Bigdata. This study will help news subscribers determine news that is unclear in its authenticity.

To counter-attack against piracy, the movie industry is continuously developing new technologies for the protection of intellectual properties, only to find them instantly useless especially in the digital age. This study shifts the focus from technology to customer behavior, and analyzes customer behaviors vis-à-vis piracy using economic models. The theoretical model of optimal holdback strategy under the threat of piracy was derived and the result shows that holdback can be used as a tool not only for hedging the loss due to piracy, but also for reducing piracy. Based on the theoretical model, we suggested proper holdback strategy for each type of movie piracy.

Designs for discriminating between two linear regression models are studied under $\Lambda$-type optimalities maximizing the measure for the lack of fit for the designs with fixed model inadequacy. The problem of selecting an appropriate $\Lambda$-type optimalities is shown to be closely related to the estimation method. $\Lambda$-type optimalities for the least squares and minimum bias estimation methods are considered. The minimum bias designs are suggested for the designs invariant with respect to the two estimation methods. First order minimum bias designs optimal under $\Lambda$-type optimalities are then derived. Finally for the case where the lack of fit test is significant, an approach to the construction of a second order design accommodating the optimal first order minimum bias design is illustrated.

We present a semi-analytical method to calculate the global evolution of the ionized state of the intergalactic medium, on the basis of physically motivated star formation histories in the early universe. This method incorporates not only the conventional scenarios in which the star formation rate is proportional to the growth rate of the halo collapse fraction, but also the more sophisticated scenarios in which the star formation is self-regulated. We show that this variance in the star-formation model strongly impacts the resulting reionization history, which bears a prospect for observational discrimination of these models. We discuss how observations of the anisotropic polarization of the cosmic microwave background and the global 21cm signal from the high-redshift universe, most notably by Planck and EDGES, may probe the history of reionization.
