Background: Spinal zaprinast, phospodiesterase inhibitor, has been shown to have an antinociception through an increase of cGMP. The aim of this study was to examine the role of spinal adrenergic and cholinergic receptors on the antinociceptive action of intrathecal zaprinast. Methods: Rats were implanted with lumbar intrathecal catheters. After formalin injection, formalin-induced nociceptive behavior (flinching response) was observed for 60 min. After observing the effect of intrathecal zaprinast, antagonism of intrathecal prazosin, yohimbine, atropine and mecamylamine for the effect of zaprinast were evaluated. Results: Intrathecal zaprinast produced a dose-dependent suppression of formalin-induced flinches in both phases of the formalin test. Intrathecal prazosin reversed the antinociception of zaprinast in phase 2, but not phase 1. Intrathecal yohimbine reversed the antinociception of zaprinast in both phases. Neither atropine nor mecamylamine reversed the antinocicetive action of zaprinast. Conclusions: Intrathecal zaprinast is against the nociceptive state evoked by formalin stimulus. Alpha 2 or alpha 1 adrenergic receptor, but not cholinergic receptors, may be related to the action of zaprinast in the spinal cord. (Korean J Anesthesiol 2007; 53: 85~90)

Recently, various applications using real-time face detection have been developed as face recognition technology and hardware grows. While network service is developing and video instruments costs lower, it is needed that smart surveillance camera and service using network camera based on IP and face detection technology. However, videos should be compressed for reducing network bandwidth and storage capacity in surveillance system. As it requires high-level improvement of system performance when all the compressed frames are processed in a face detection program, fast face detection method is needed. In this paper, not only a fast way of algorithm using Haar like features and adaboost learning and motion information but also an application on broadcast system is suggested.

The purpose of the present study is to explore the experiential aspects of life changes(job and childcare) for professional female dancers after childbirth with regard to the thesis of ‘social body’ and ‘identity’. The research methodology applied Clandinin and Connelly’s narrative inquiry( 2000). There were 5 research participants including 3 dancers with childbirth experience and 2 dancers who retired after giving childbirth. The results of the study were approached largely in terms of three categories. First, in ‘Defined by my social age!’, the study explored contents on bodily changes and subjective loss as a dancer. Second, in ‘Ajumma(middle aged woman), the symbol of childbirth and aging’, the study discussed the prejudice against the social body and the fear regarding one’s return as a dancer. Third, in ‘Fighting back against the social body’, the study uncovers self-conquest with the purpose of returning as a perfect dancer and introspective discourses as a mother. The social and cultural loss of professional female dancers in the labor field is experienced through the ‘social body’ following pregnancy and childbirth. An approach toward such subjective feeling and experience is research that is necessary for dance studies, with academic implications in this respect.

The era of realistic broadcast with high fidelity has come after the wide-spread distribution of UHD display and the transmission of UHD experimental broadcast in CATV. However, UHD broadcast now has constraint because it requires much amount of bandwidth and data in broadcasting transmission and production system. Not only HEVC(High Efficiency Video Codec) which has more than two times higher compression rate but also cloud-based editing system would be the key to solve the problems above. Also, fast scene change detection of videos is needed to index and search UHD videos smoothly. In this paper, therefore, a method is proposed to index and search the scene change information of large volume UHD videos compressed with high-efficiency codec. Application usages of fast detection of scene change information in various UHD video environments are considered by using this algorithm.

해부학실습과정은 소그룹 단위로 실습이 진행되면서 팀워크 조성, 성실성, 능동적 학습, 의사소통으로 효율적인 협동학습을 필요로 하며, 이는 전문직업성의 주요한 요소에 해당한다. 본 연구의 목적은 해부학실습 과정에서의 전문직업성을 동료와 본인이 평가하여 학업성취도와의 상관관계를 확인하는 것이다. 2015년 부산대학교 의학전문대학원 1학년 학생의 ‘인체의 구조와 기능’ 과정에서 해부학실습에 참여한 108명의 학생들 대상으로 설문지를 통한 동료평가와 자기평가를 실시하였다. 동료평가와 자기평가의 중앙값을 중심으로 상하로 나누어 높은 동료평가/높은 자기평가, 높은 동료평가/낮은 자기평가, 낮은 동료평가/높은 자기평가, 낮은 동료평가/낮은 자기평가 4개의 집단으로 분류하였다. 동료평가와 자기평가에 따른 4개 집단 중에서 높은 동료평가 집단이 낮은 동료평가 집단에 비해 학업성취도 중에서 과정시험 (F=3.24), 학점 (F=3.54), 예습시험 (F=3.94), 실기시험 (F=3.60) 성적에서 다른 집단과 유의한 차이를 보였다. 학업성취도를 구성하는 성적변인 사이에는 전반적으로 높은 상관계수를 보였다. 그러나 성적변인 중에서 실습시험 성적은 다른 변인과의 상관관계에서 집단에 따라서 차이를 보였다. 실습시험과 다른 변인 사이의 상관관계가 가장 높은 집단은 높은 동료평가/높은 자기평가 집단이었으며, 이어서 낮은 동료평가/ 낮은 자기평가 집단, 낮은 동료평가/높은 자기평가 집단이었으며 높은 동료평가/낮은 자기평가 집단이 상대적으로 낮은 상관관계를 보였다. 결론적으로 동료평가와 자기평가의 상대적 차이에 따른 집단을 대상으로 학업성취도에서의 유의한 차이를 확인하여 이러한 분류체계가 전문직업성의 작업습관에 대한 평가도구로 활용이 가능하며, 동료평가와 자기평가가 모두 높은 집단의 경우는 맥락적 학습에 보다 잘 적응하는 집단으로 생각되었다. Gross anatomy, with cadaver laboratory dissection, is in a unique position to preside over a rich number of activities such as the team work, integrity, active learning, communication in the small group-all aspects of professional conduct. The purposes of this study are to investigate the correlation of professionalism with academic performance and the characteristics of groups of students in the performance variables. First-year Pusan National University School of Medicine students (n=108) from the Class of 2015 taking the gross anatomy course were required to do the self- and peer assessment about the professional behaviors of each of the six members of their dissecting group. The students were classified into one of four subgroups based on their deviation from the self- and peer assessment medians, such as high peer/high self (HP/HS), high peer/low self (HP/LS), low peer/high self (LP/HS), low peer/low self (LP/LS). There were significant higher scores in the high peer groups (HP/HS, HP/LS) in comparison with low peer groups (LP/HS, LP/LS) in the academic performance of end-of-term (F=3.24), credit (F=3.54), pre-Lab (F=3.94), practical examination (F=3.60) scores. Significant correlations among academic performance variables were observed generally. There were some differences in the correlation in the practical examination and other variables. The relatively high correlation between practical examination and other variables is HP/HS, followed by LP/LS, LP/HS and then HP/LS. In conclusion, peer- and self assessment subgroups showed a significant differences in the academic performance. This assignment would be available to evaluate work habits of professionalism in the gross anatomy laboratory. It is suggested that HP/HS group was more adaptable in the contextual leaning the gross anatomy course.
