Objective : The maintenance of the correction of kyphotic deformity is one of the difficult problem in tuberculous spondylitis after anterior debriment and fusion with tricortical bone graft. The goal of this study is to find out the efficacy of titanium mesh cage impacted with autogenous bone chip in tuberculous spondylitis treated with anterior intervertebral fusion. Materials and Method : Twelve patients were treated with anterior intervertebral fusion using titanium mesh cage for tuberculous spondylitis from January 1996 to June 1999. We analized the changes in the correction of kyphotic deformity, changes of ESR and CRP, fusion state and recurrence after anterior intervertebral fusion with titanium mesh cage. Results : Clinical symptoms were improved in all twelve patients without any neurologic complications. The mean kyphotic angle corrected was 7.3 degrees immediately after operation, but the loss of correction of kyphotic angle was 2.2 degrees after 3 months and 2.6 degrees after 6 months. We found that the loss of correction of kyphotic deformity occurred mainly within the first 3 months after surgery. Only one patient, suffered from acute hepatic failure after first operation and had an insufficient anti-tuberculous medication therapy, showed recurrence of tuberculous spondylitis after 6 months. The patient underwent a second operation with posterior fixation procedure with good outcome. The changes of ESR and CRP were not specifically important factor to reveal recurrence of tuberculosis of the spine in our series. Conclusion : The surgical procedure of tuberculous spondylitis using titanium mesh cage with bone chip seems to be an effective procedure to minimize loss of the correction of kyphotic deformity without any aggravating inflammatory change and recurrence with titanium mesh cage, when sufficient debridement and anti-tuberculous chemotherapy are achieved.

The intradural lumbar disc herniation which was first described by Dandy in 1942 is unusual. The pathogenesis is obscure and preoperative diagnosis is not easy. The patient usually have more severe neurologic deficits than those found in the much more common extradural disc herniations. We experienced two cases of the intradural lumbar disc herniation who had previous disc operations and the symptoms and neurologic signs were improved after removal of the intradural sequestration of disc fragments.

자본시장법상 헤지펀드 규제에 관한 법적 고찰

정주호(Jeong, Ju-Ho) 숭실대학교 법학연구소 2015 法學論叢 Vol.33 No.-

우리나라는 자본시장법을 통해 전문사모집합투자기구에 대한 규정으로 헤지펀드제도를 운영하고 있다. 헤지펀드의 도입목적은 세계적인 투자은행 육성과 함께 해외투자자본을 적극적으로 유치하고 국내투자자본의 유출을 최소화하여 국내 금융시장의 자금 유동성과 효율성을 높이는데 있다. 일반적으로 헤지펀드는 뮤츄얼펀드(Mutual Fund), 사모투자펀드(Private Equity Fund), 벤처캐피탈(Venture Capital)등의 여타 투자기구에 비해 상대적 위험분산 기능을 가지고 있고, 절대수익률을 추구하며 시장수익률로부터 영향이 적다. 헤지펀드는 통상적인 투자시장의 영향에서 벗어나 분산투자와 다양한 투자전략으로 절대수익률과 안정적인 수익률을 추구함으로써 투자자의 욕구를 충족시켜 준다. 반면 헤지펀드의 특성상 정해진 기간내에 다양한 투자대상을 통해 높은 수익을 추구하게 되고 한정된 시간 내에 최대한 수익을 얻기 위해 단기적인 기간 수익에 몰입할 가능성이 높아진다. 이 과정에서 펀드운용과 관련하여 내부자거래나 시세조종 등의 불공정거래행위가 발생하기도 하며, 차입규모가 큰 헤지펀드가 포지션을 일시에 청산할 경우 금융시장의 안정성이 위험에 노출될 가능성이 높아진다. 본 논문의 목적은 헤지펀드에 대한 이해와 함께 세계 각국의 관련 정책과 규제동향을 살펴보고 우리나라 자본시장법상 헤지펀드에 관한 규제에 대한 검토를 통해 헤지펀드의 안정적 성장을 통한 금융시장 활성화와 투자자 보호라는 큰 틀에서 부합하는 자본시장법상 헤지펀드 규제의 방향을 제시하고자 한다. Through the revision of the Capital Market Act in 2011, our country introduced and has regulated the hedge fund by the regulation on the speciality private equity collective investment scheme. The introduction of hedge fund aims at positively attracting the foreign investment capital together with cultivation of the global investment bank and at minimizing the outflow of the domestic investment capital, so that it can improve the fund liquidity and effectiveness of the domestic financial market. The hedge fund generally has a function of the diversification of risks relatively compared to the other investment mechanisms such as the mutual fund, private equity fund and venture capital; seeks the absolute rate of return; and is little affected by the market return. By pursuing the absolute and stable rate of return with diversified investment and various investment strategies getting out of the usual investment market, the hedge fund satisfies investors’ desire. On the other hand, from the nature of the hedge fund, it is more likely to seek the high profitability through various investment objects within a set period and to immerge itself in the short-term revenue to make maximum profits within a limited time. In these processes, there are sometimes the unfair transactions such as the insider transaction or price manipulation related to the operation of fund, and in the case that a hedge fund with a large scale of borrowing settles its position at once, financial market stability is more likely to be exposed in danger. This research aims at investigating the relevant policies and regulation trends of the other countries in world as well as the understanding of the hedge fund; and through the review of the regulation on the hedge fund under our Capital Market Act, it aims at suggesting a direction of regulation on the hedge fund under the Capital Market Act, in accordance with the large frameworks of the financial market activation and investor protection through the stable growth of hedge fund.

According to the KT telecommunication statistics, people stayed inside their houses on an average of 11.9 hours a day. As well as, according to NSC statistics in the united states, people regardless of age are injured for a variety of reasons in their houses. For purposes of this research, we have investigated an abnormal event detection algorithm to classify infrequently occurring behaviors as accidents, health emergencies, etc. in their daily lives. We propose a fusion method that combines three classification algorithms with vision pattern, audio pattern, and activity pattern to detect unusual user events. The vision pattern algorithm identifies people and objects based on video data collected through home CCTV. The audio and activity pattern algorithms classify user audio and activity behaviors using the data collected from built-in sensors on their smartphones in their houses. We evaluated the proposed individual pattern algorithm and fusion method based on multiple scenarios.

The self-driving cars identify appropriate navigation paths and obstacles to arrive at their destinations without human control. The autonomous cars are capable of sensing driving environments to improve driver and pedestrian safety by sharing with neighbor traffic infrastructure. In this paper, we have focused on pedestrian protection and have designed an improved localization algorithm to track mobile users on roads by interacting with smart traffic lights in vehicle environments. We developed smart traffic lights with the RSSI sensor and built the proposed method by improving the Kalman filter algorithm to localize mobile users accurately. We successfully evaluated the proposed algorithm to improve the mobile user localization with deployed five smart traffic lights.

최근 다양한 질병 때문에 사람들은 집 안에서 많은 시간을 보내고 있다. 집 안에서 다치거나 질병에 감염되어 타인의 도움이 필요한 1인 가구의 경우 타인에게 도움을 요청하기 어렵다. 본 연구에서는 1인 가구가 집 안에서 부상이나 질병 감염 등 타인의 도움이 필요로 하는 상황인 이상 징후를 탐지하기 위한 알고리즘을 제안한다. 홈 CCTV를 이용한 영상 패턴 탐지 알고리즘과 인공지능 스피커 등을 이용한 음성 패턴 탐지 알고리즘, 스마트폰의 가속도 센서를 이용한 활동 패턴 탐지 알고리즘, 공기청정기 등을 이용한 먼지패턴 탐지 알고리즘을 제안한다. 하지만, 홈 CCTV의 보안 문제로 사용하기 어려울 경우 음성, 활동, 먼지 패턴 센서를 결합한 융합방식을 제안한다. 각 알고리즘은 유튜브와 실험을 통해 데이터를 수집하여 정확도를 측정했다. Recently, people are spending a lot of time inside their homes because of various diseases. It is difficult to ask others for help in the case of a single-person household that is injured in the house or infected with a disease and needs help from others. In this study, an algorithm is proposed to detect emergency event, which are situations in which single-person households need help from others, such as injuries or disease infections, in their homes. It proposes vision pattern detection algorithms using home CCTVs, audio pattern detection algorithms using artificial intelligence speakers, activity pattern detection algorithms using acceleration sensors in smartphones, and dust pattern detection algorithms using air purifiers. However, if it is difficult to use due to security issues of home CCTVs, it proposes a fusion method combining audio, activity and dust pattern sensors. Each algorithm collected data through YouTube and experiments to measure accuracy.

이 연구는 뉴테러리즘 시대를 맞이하여 국내 거주 외국인 대학생을 대상으로 테러리즘에 대한 인식을 알아보기 위하여 수행 되었다. 즉, 이질적 한국 문화에 적응하기 위하여 발생하는 다양한 스트레스가 자생테러리즘이나 외로운 늑대 테러리즘과 같은 뉴테러리즘 형태의 인식에 미치는 영향을 알아보고자 하였다. 이를 위하여 수도권 대학교에서 수학 중인 외국인 학생 199명을 대상으로 문화적응 스트레스, 사회적 지지, Precht(2007)의 초기-급진화 인식, 테러리즘 비호감성에 관한 설문을 실시하였고, 다중회귀분석을 통하여 결론을 도출하였다. 분석 결과, 이질적 문화적응에 대한 두려움이 통계적으로 유의미하게 테러리즘 비호감성에 부적인(-) 영향을 미치는 것으로 나타났다. 사회적 지지에서는 어려울 때 도움을 주는 친구가 있을 때 테러리즘 비호감성이 유의미하게 증가하는 것(+)으로 나타났다. 마지막으로 초기-급진화 인식은 테러리즘 비호감성에 통계적으로 유의미한 정적(+) 영향을 미치는 것으로 나타났다. This study attempted to understand the perception of terrorism among international university students living in Korea in the era of new terrorism. The purpose of the study was to investigate the effect of diverse stresses on the perception of new terrorism types, such as homegrown terrorism or lone-wolf terrorism, in order to examine for international students to adapt to Korean culture that is totally different from their own. In other words, this study focused to investigate how cultural adaptation stress of international students influence on terrorism perception, how the level of Korean society’s social supports influence on terrorism perception, and how the early-stage perception of Precht’s radicalization theory influence on terrorism perception. For this purpose, this study surveyed a total of 199 international students studying at universities located in Seoul metropolitan area about their cultural adaptation stress, their perception of the level of Korean society’s social supports, the early-stage perception of Precht’s radicalization, and their levels of sensitivity to terrorism discomfort. Multiple regression technique was applied for analysis. There are numerous studies on finding the causes of terrorism, but this study focused on finding causes to prevent terrorism. It is s very meaningful study to examine who is positive about terrorism and who thinks about terrorism negatively under the similar stressful situations. The results of the study showed that only cultural adaptation stress variable had a statistically significant negative effect on fear of heterogeneous culture adaptation among five other sub-variables. The sub-variable of ‘whether they had anyone to help them under difficult situations’ of the social supports variable had a statistically significant positive effect on terrorism discomfort. The early-stage perception variable had a statistically significant positive effect on terrorism comfort.
