Studies on artificial intelligence have been developed for the past couple of decades. After a few periods of prosperity and recession, a new machine learning method, so-called Deep Learning, has been introduced. This is the result of high-quality big- data, an increase in computing power, and the development of new algorithms. The main targets for deep learning are 1D audio and 2D images. The application domain is being extended from a discriminative model, such as classification/segmentation, to a generative model. Currently, deep learning is used for processing 3D data. However, unlike 2D, it is not easy to acquire 3D learning data. Although low-cost 3D data acquisition sensors have become more popular owing to advances in 3D vision technology, the generation/acquisition of 3D data remains a very difficult problem. Moreover, it is not easy to directly apply an existing network model, such as a convolution network, owing to the variety of 3D data representations. In this paper, we summarize the 3D deep learning technology that have started to be developed within the last 2 years.

본 연구는 산재보험에서 실시해온 산재근로자 사례관리서비스에 대한 그간의 성과를 살펴봄으로써 산재근로자 사례관리서비스의 발전방향을 모색하는 기초자료를 제공하기 위함이다. 이를 위해 2012 년에서 2020년까지 근로복지공단의 산재근로자 사례관리서비스 실적과 2017년 요양을 종결한 산재 근로자 중 사례관리서비스를 받은 집단 100명과 서비스를 받지 않은 집단 101명을 대상으로 사례관 리서비스 만족도 설문조사를 실시하였다. 분석 결과 사례관리서비스 이용자가 미이용자에 비해 직업 복귀율이 더 높게 나타났고, 원직장 복귀율도 더 높게 나타났다. 재활서비스 만족도 역시 사례관리 서비스 이용자가 미이용자에 비해 더 조기에 서비스를 이용하였고, 재활서비스 효과도 더 좋은 것으로 파악되었다. 다만, 사례관리서비스 대상자 선정 시 직업복귀가 보다 용이한 대상자를 선정한 부분이 있었고, 사례관리서비스 욕구가 없는 불필요한 대상자를 선정한 문제점이 나타났다. 그리고, 산재근로 자 욕구중심이 아닌 서비스 공급자 중심의 서비스 운영에 대한 문제점도 나타났다. 사례관리서비스 만족도에 대해서는 확신성과 유형성은 만족도가 높았으나 신뢰성과 대응성에 대한 중점 개선노력이 필요한 것으로 나타났다.

In Korea. B-type hepatitis is a disease with high morbidity. Entering the 1980's, the B-type hepatitis vaccine was produced domestically and studies on its immunity effects were subsequently activated. The studies focus on measureing the surface-antibody-positive-rate(SAPR) for each parameter influencing the vaccine's immunity effects. However, it is difficult to generalize the resulting values, which range widely or show inconsistency. This study was implemented to obtain generalized and comprehensive results by analyzing narratively and quantitatively, through a meta-analysis data from the indivisual studies which yielded the following conclusions : 1. In the case of SAPR by sex, the rate for females were higher than for males. 2. In the case of SAPR by age, it is impossible to get overall combined estimate because applied criteria were different. But no significant differences by age were found in all of 7 tested theses. 3. As for the vaccinated dose. school children with vaccinations of half the recommended dose showed the higher SAPR, but this was shown to be statistically insignificant. It appeared that the quantitatively-reduced vaccination for nenates did not lower their ability to produce antibodies. 4. In the case of SAPR by kinds of vaccines. heat-treated hepaccine showed the highest rate out of human plasma. while the DNA recombinant vaccine showed. on the whole, higher rate than Hepavax-B. 5. In the case of SAPR by injection frequency, the rate for the muscular injection group was significantly high subject to the first and second injection, but any differences after the third injection were not found. 6. In the case of SAPR by injection intervals, the rate for the 0-1-2 group was significantly high in comparison with the rate for the 0-1-6 group subject to first injection but thereafter no differences were found. 7. The SAPR in anti-HBc positive was found to be higher than in negatives.
