장골 이식을 동반한 임플란트 수술 후의 합병증; 증례보고
최영준,최원철,Choi, Young-Jun,Choi, Won-Cheul 대한악안면성형재건외과학회 2007 Maxillofacial Plastic Reconstructive Surgery Vol.29 No.4
In a one-stage approach, where the implant installation is performed simultaneously with the iliac bone graft, various complications are observed. The observed complications are as follows; severe bone resorption at the maxillary anterior region and the area adjacent to the nasal cavity, shortage of soft tissue to cover the augmented alveolar bone, difficulties with oral hygiene care caused by the diminished vestibular space and non-esthetic prosthesis. These are good reasons for choosing the two-stage approach over the one-stage approach in spite of all the advantages it has, and should be taken into careful consideration when diagnosing and planning treatment using the one-stage approach.

Objectives : This study is planned to classify correlation between thoracic kyphosis angle and prevalence of cervical intervertebral disc. Methods : We Measured the thoracic kyphosis angel of the 110 men and 179 women patients with neck pain in 00 Korean Medicine Hospital. We use Cobb's angle method and Thoracic cage dimension method for measuring the thoracic kyphosis. And We use Magentic Resonance Imaging(MRI) for classifying the patient who has cervical intervertebral disc or not. Results : 1. There was statistical difference on the thoracic cage dimension with gender(P<0.001), while there was no statistical difference on Cobb's angle with gender(P=0.882). 2. Age and thoracic cage dimension(r=0.383) is statistically more correlative than age and cobb's angle(r=-0.59). Conclusions : 1. Thoracic cage dimension and gender, Thoracic cage dimension and age were statistically concerned on patient who has neck pain, while Cobb's angle had no statistical correlation with age and gender. 2. There was no statistical difference on the Cobb's angle and Thoracic cage Dimension between patient who has one or more cervical disc herniation(Protrusion disc, Extrusion disc) segment and patient who didn't have cervical disc herniation(Protrusion disc, Extrusion disc) segment.

The deployable space structure is necessary to minimize the satellite volume and launch cost. For the deployment, passive deployment mechanism has widely been used to attenuate a latch shock induced when the structure is just fully deployed. To reduce the latch shock, viscous damper is applied to the passive deployment mechanism and it can control the deployment speed of the structure. In this paper, dynamic analysis of the deployable space structure using the passive deployment mechanism with the viscous damper has been performed. The viscous damping values have been optimized through numerical simulation. The satellite's attitude influenced by pyro activation for the release of the structure has also been investigated.
무용, 영상 그리고 음악을 연결하는 상호작용 행위예술 기술 현황과 향후의 미래 고찰

무용, 영상 그리 고 음악이 컴퓨터에 의해 종합지어지는 예술의 형태는 더 이상 낯선 장르 가아니다. 더욱이 무용과 영상, 영상과 음악, 음악과 무용 간에 얼마만의 interactivity가 구현되었느냐에 많은 작가들의 관심은 집중 되어 지고 있으며 이러한 새로운 기술 구현이 작품의 완성도로 비추어지는 경우 도 간혹 생긴 다. 그리하여 이러한 기술의 현황을 살펴보고 발전 방향을 고찰 해 보는 것이 아티스트들에게는 매 우 흥미로운 논쟁거리가 되고 있다. It is not strange anymore that we combine dance, video and music to make a new form of art. Especially artists focus the completion of interactivity between dance and video, video and music, music and dance. Sometimes these smooth accomplishments of the technologies could give the artist a big achievement. Thus, it is a good topic to artist to review current and future technologies.
중고령층의 자영업 경험이 복지인식에 미치는 영향에 관한 연구
최영준(Choi, Young Jun),이승준(Lee, Seung Jun) 한국사회정책학회 2015 한국사회정책 Vol.22 No.1
베이비붐 세대 중고령층이 조기에 주된 일자리에서 퇴직하면서 자영업의 과잉진입과 조기폐업 등이 사회적 이슈가 되고 있다. 또한, 중고령층의 자영업 실패가 불안한 노후로 이어지는 것에 대한 우려도 높아지고 있다. 이와 관련하여 자영업 진입이나 퇴출과 관련된 연구들과, 노후소득보장이나 빈곤 등에 관한 연구들이 진행되었다. 하지만 자영업의 동태적인 경험이 이들의 복지인식에 어떠한 영향을 미치는지에 대한 연구는 수행되지 못하였다. 사회정책이 국민의 지지가 중요한 변수이며, 핵심적인 유권자 계층인 중고령층의 상당수가 자영업을 경험한다는 차원에서 이들의 복지인식은 복지국가 정치적 지속가능성에 중요한 함의를 가진다. 이에 본 연구에서는 2007년 경제위기라는 특수적 상황 이후인 2008년과 2009년에 새롭게 자영업에 진입한 이들의 사회경제적 특성을 한국노동패널과 한국복지패널을 통하여 파악하고, 이러한 경험이 이들의 복지인식에 어떠한 변화를 주었는지를 추적하고자 한다. 새롭게 자영업에 진입한 이들의 변화를 지속적으로 자영업에 있었던 집단 및 상용직에 있었던 집단과 비교함으로써 자영업 경험이 주는 복지인식 변화를 명확히 하고자 한다. 본 연구를 통해서 자영업의 불안정성을 파악하고, 사회정책의 사각지대에 놓인 자영업의 경험이 사회정책에 대한 부정적 인식을 강화시킴을 규명하였다. The early retirement from the primary job and the excessive entry to the self-employment has become one of the serious social problems. After the excessive entry, it is reported that many of them failed their business, which would lead to the economic insecurity of their old-age. Much has been written about the entry and the exit of the self-employment, but there are few studies on how the vulnerability of the self-employed has influenced their welfare attitudes. Given that the political sustainability of the welfare state relies on people’s supports and many of middle and older people have experienced self-employment, it is important to research the effect of self-employed experiences on welfare attitudes. In this context, this research aims to analyze experiences of the new self-employed after the financial crisis in 2007 and to analyze how these experiences have affected their welfare attitudes. It will use the Korean Labor Panel and the Korea Welfare Panel for the analysis. This study will discuss the vulnerability of the self-employed and will argue that the experience of the self-employed tend to decrease welfare supports rather than increase.
