  • 자동차의 안전성 향상에 대한 연구는 오랜 기간 다양한 분야에서 진행되고 있다. 이 시스템은 단일 카메라를 이용하여 차선을 감지함으로써 차선 침범을 방지한다. 시스템은 파티클 필터를 이용해 도로 모델 파라미터를 조정하고 두 개의 detector가 도로 모델의 일치도를 계산한다. Detector는 차선의 모양과 색이라는 대표적인 특징을 이용한다. 파티클 필터를 전 프레임에서 사용한 모델 파라미터를 이용하여 신속한 처리를 한다.

  • 본 논문은 가상 골프 시스템에서 골프 공의 구질을 찾기 위한 새로운 센싱시스템을 제안한다. 제안된 시스템은 2개의 수평 센싱라인과 한 개의 광원으로 구성된 간단한 구조이다. 센서 위에 드리워진 공과 클럽의 그림자 정보를 0,1의 binary 형태로 만들어 놓은 원시데이터는 PC로 보내지게 되고 PC는 원시 데이터에서 공과 클럽의 영역들을 구분한다. 구분된 각각의 그림자 영역에서 속도나 초기 움직임 방향, 각도 등이 계산된다. 그리고 계산된 특징 정보를 이용해서 골프 공의 구질을 측정하고 제안된 센싱시스템의 효율성을 보인다.

  • 산업통상자원부에서 제공하는 KOTRA 무역 데이터는 해당 품목과 해당 국가에 대하여 GDP, 관세율, 비즈니스 점수, 과/차년도 수출금액 등을 제공한다. 그러나 무역 수출품목은 수 없이 많을 뿐더러 그에 따른 대량의 데이터를 매년 인간의 분석을 통해 유의미한 결과를 이끌어내는 것은 상당히 큰 시간과 비용을 요구한다. 따라서 이번 연구에선 대량의 데이터를 학습하여 단기간에 저비용으로 결과를 예측할 수 있는 심층신경망 모델을 구현해 보았다.

  • As a result of research, the characteristics of the general costumes from the king Young-Cho period to the king Jung-Cho period in Genre Paintings of Mung-Hyun Oho, Yong Yun, In-Sang Lee, Hee-Eon Kang follows. First, the typical man wore his hair in a topknot(sangtu), and put on 'Bung-gu-ji', 'Lip', or a scarf on his head. The length of the 'Jeogori'(Korean traditional jacket) was long enough to cover the waist. Dress for work had side slits, and had half length sleeve Jeogori, and short pants looked like 'Jam-bang-i'. They went barefoot and wore 'Jipsin'(Korean traditional straw shoes). Dress for outdoor was 'Po' that knot at front of chest by band. 'Baji'(slacks) were with knot below knee, worn 'Hang-jun'(ankle band) and the width of slacks was suitable. They were 'Beoseon'(Korean traditional socks) and shoes. Second those in the upperc1ass and those in the military put on 'Mang-geon', 'Gat', 'Sa-bang-gan', 'Tang-geon', 'Bok-geon' on their head on a topknot. Most of them wore 'So-chang-i', 'Jung-chi-mag' or 'Do-po'. The length of Jeogori covered the waist or the hip and were tied with 'Go-rum'(ribbon). Baji was tied with Hang-jun and 'Dae-nim'. The waist of the slacks were tied with a dark colored waist-band and folded down their waist of slacks. They wore white color Beoseon and 'Hye' or dark color leather shoes. They wore 'Sup'(assistant of arm) for bow. It showed the lifestyle of the 18C with fan, 'Be-ru', 'Mug', 'Yun-jug', teacup, pot, etc. Third, child's hair was short or knotted to the back of the head. The length of Jeogori reached waist line, Git of Jeogori was 'Dunggurai-Kit'(shape of round) and other style Jeogori, which reached the hip line, had side-slit. Baji was tied with Dae-nim, and the width of the slacks is suitable. They hang 'Yum-nang'(Pocket). Final, most women worked outdoors wearing their hair in a high twisted style, or covered it with scarf. They wore Jeogori and 'Chima'(Korean traditional skirts), Bagi. They folded up the sleeves of the Jeogori. And they folded the 'Jambang-i-styled' pants to just above the knees, fastening at the waist. When they wore skirts, they also wore underpants under the skirt that went down to the knees. Most of them went barefoot and wore straw shoes, Jipsin. Through genre paintings, we can understand the ways and forms of our ancestor's clothing. And with our understanding, interest, and passion, we can be familiar with Hanbok in our daily life by succeeding and creating its peculiar style. And then we can promote the globalization of Hanbok.

  • Background and Objectives: Non-small-cell lung cancer (NSCLC) represents approximately 80% of all lung cancers. Unfortunately, at their time of diagnosis, most patients have advanced to unresectable disease with a very poor prognosis. The oriental herbal medicine HangAm-Plus (HAP) has been developed for antitumor purposes, and several previous studies have reported its therapeutic effects. In this study, the efficacy of HAP was evaluated as a third-line treatment for advanced-stage IIIb/IV NSCLC. Methods: The study involved six patients treated at the East- West Cancer Center (EWCC) from April 2010 to October 2011. Inoperable advanced-stage IIIb/IV NSCLC patients received 3,000 or 6,000 mg of HAP on a daily basis over a 12-week period. Computed tomography (CT) scans were obtained from the patients at the time of the initial administration and after 12 weeks of treatment. We observed and analyzed the patients overall survival (OS) and progression-free survival (PFS). Results: Of the six patients, three expired during the study, and the three remaining patients were alive as of October 31, 2011. The OS ranged from 234 to 512 days, with a median survival of 397 days and a one-year survival rate of 66.7%. In the 12-week-interval chest CT assessment, three patients showed stable disease (SD), and the other three showed progressive disease (PD). The PFS of patients ranged from 88 to 512 days, the median PFS being 96 days. Longer OS and PFS were correlated with SD. Although not directly comparable, the OS and the PFS of this study were greater than those of the docetaxel or the best supportive care group in other studies. Conclusion: HAP may prolong the OS and the PFS of inoperable stage IIIb/IV NSCLC patients without significant adverse effects. In the future, more controlled clinical trials with larger samples from multi-centers should be conducted to evaluate the efficacy and the safety of HAP.

  • The purpose of the study was to find an effect of phospholipid-free vegetable oils on the serum lipids and proteins of Sprague-Dawley rats. All experimental rats were fed ad libitum for 60days with the mixture of starch: casein: salt mixture: vitamin mixture (60:18:4:1) and at the same time fed administratively with 1 ml of soybean oil, corn oil and sesame oil bought in market as source of phospholipid-free vegetable oils(PFVO) and those extracted directly by and oil press as source of phospholipid-containing vegetable oils(PCVO) respectively. At the last day of experimental period, the rats were fasted for 12 hours and decaptitated to collect blood for analysis of serum lipid and protein. The results of this study were summerized as follows. 1. The supplementation of dietary phospholipid decrease food efficiency ratio and the growth rate of experimental rats. 2. The supplementation of dietary phospholipid improve correlation coefficient of body weight and organ weights. 3. The supplementation of dietary phospholipid increase the level of serum phosphatidylethanolamine. Therefore, I think that we must eat dietary phospholipid unpurified from vegetable oil to prevent development of atherosclerosis and fat liver.

  • The Contemporary Korean fiction today to a certain context infringes on the outskirts of mainstream literary theories diversified to an extent that anything and everything that are printed are defined as literature. The two fictions that the study is based upon, probably, shows the effects of postmodernism in Korean fictional 'space' in that the representation of the said fictions veers clear from that with which one might associate in contemplating the traditional Korean fiction. The study, though it seems, based on a more of a societal perspective rather than traditional literary perspective is to be noted in reference with the postmodern theories that we identity with today. The paper takes look at the changes that can be noted in the fictions: Kyung ma jang ga nun gil by Ha Il-ji and Oak tap hang by Park Sang-woo. The main objective of the paper is that it tried to identify the cultural identity of Koreans through the descriptions found in the two works. While concluding as to why these two fictions can be categorized as belonging to the genre of postmodernism the research also tries to formulate what and how postrnodernism can be discerned in fictional genre and this especially in today's Contemporary Korean fiction.
