절리 지반에서 2단계로 굴착되는 터널의 거동특성에 대한 실험적연구
박승준,김동갑,이상덕,Park, Seung-Jun,Kim, Dong-Gab,Lee, Sang-Duk 한국터널지하공간학회 2004 터널기술 Vol.6 No.4
This study is intended to investigate the geotechnical behavior of jointed mass on tunnel excavation experimentally. Laboratory test were conducted in various conditions of distance from joint to tunnel and in-situ stress ratio ($K_0$). In case, the ground around the tunnel that has the joint angle $90^{\circ}$ generate the greatest influence in crown and far shoulder from joint. If the in-situ stress ratio is low, tangential stress of side wall that is opposite side of the joint is increased more than in crown. Otherwise in case, joint angle $45^{\circ}$, the generated compress stress is found out that left side of the tunnel of near the joint has influence on stability of the tunnel about 3 times than non-jointed rock.

Congenital coronary arteriovenous fistulas are uncommon, but well documented lesions. There are two types of congenital coronary arteriovenous fistulas according to drainage sites, the cardiac chambers or the pulmonary trunk. Especially congenital coronary arteriovenous fistula originating from the left coronary artery is rare. Two cases will be described of the two patients in whom fistulas communicating between the right coronary artery and the right atrium, left coronary artery and the main pulmonary artery each other.

생활수준 향상과 주 40시간 근무제 도입등에 따라 해양성 휴양 및 관광 수요는 증가하고 있으나 이를 수용할 수 있는 어항 기반은 매우 취약한 편이다. 다양한 관광수요를 만족시키는 환경친화적 관광기능어항 개발이 절실한 실정인 것이다.

자율주행을 위한 딥러닝 기반의 차선 검출 방법에 관한 연구
박승준,한상용,박상배,김정하,Park, Seung-Jun,Han, Sang-Yong,Park, Sang-Bae,Kim, Jung-Ha 한국산업융합학회 2020 한국산업융합학회 논문집 Vol.23 No.6
This study used the Deep Learning models used in previous studies, we selected the basic model. The selected model was selected as ZFNet among ZFNet, Googlenet and ResNet, and the object was detected using a ZFNet based FRCNN. In order to reduce the detection error rate of FRCNN, location of four types of objects detected inside the image was designed by SVM classifier and location-based filtering was applied. As simulation results, it showed similar performance to the lane marking classification method with conventional 경계 detection, with an average accuracy of about 88.8%. In addition, studies using the Linear-parabolic Model showed a processing speed of 165.65ms with a minimum resolution of 600 × 800, but in this study, the resolution was treated at about 33ms with an input resolution image of 1280 × 960, so it was possible to classify lane marking at a faster rate than the previous study by CNN-based End to End method.

Uterine artery embolization for the treatment of uterine leiomyomas is gaining acceptance as an effective alternative to surgical treatment in preserving uterus and reducing symptoms. Vaginal expulsion of leiomyomas after UAE is uncommon, and has been regarded as a side effect of the procedure, as well as a natural phenomenon of treatment response. A-28-year-old unmarried woman who has been suffered from menorrhagia underwent UAE. MRI revealed the remnant leiomyomas were reduced in size and volume and also symptoms of leiomyomas were much improved. After 6 month, We`ve made sure about non-visualization of leiomyoma on follow-up pelvic dynamic MRI. We report this rare case of vaginal expusion of intramural leoimyoma with a brief literature.

패널 연립방정식 모형을 이용한 OECD 국가의 국방비 및 사회복지·보건비 결정요인과 상충관계 분석
박승준 ( Seung Jun Park ),권오성 ( O Sung Kwon ) 한국국제경제학회 2016 국제경제연구 Vol.22 No.4
Recently, North Korea`s increasing threats and North-East Asian countries` arms race stress the importance of national defense in South Korea. At the same time, low birth rate and aging society`s problem have been the major causes of increasing demand for social welfare services. In this respect, we analyze the determinants of OECD countries` national defense and social welfare·health expenditures and the trade-off relationship between two fiscal expenditures by using PSEM. This paper shows that an increase in national defense expenditure doesn`t significantly decrease social welfare·health expenditure in the analysis of the determinants of social welfare expenditure when we exclude South Korea from OECD countries` data. However, we find that there is an evident trade-off relationship between national defense and social welfare·health expenditures in the analysis of the determinants of both expenditures when we include South Korea in OECD countries` data. These results imply that national security crisis plays a part of financial restriction of social welfare budget, while the change in social and economic environment constrains the national defense budget from securing the sufficient level in South Korea.
