본 논문에서는 반 깜박임 선택 기법을 이용한 응시 상호작용(Gaze interaction) 방법과 이를 이용한 착용형 증강현실 시스템(Wearable Augmented Reality system)이 제안 된다. 응시 상호작용은 가장 쉽고 자연스러우며 빠른 방법이며, 광투과 HMD기반의 착용형 AR 시스템에 매우 적합한 기법이다. 이 시스템은 사용자의 응시 좌표와 반 깜박임(Half blink)을 인식하여 사용자가 바라보고 있는 객체의 정보를 HMD에 출력한다. 이를 통해 마이더스 터치 문제(Midas touch problem)를 해결하여 사용자의 의도를 정확히 전달할 수 있게 된다. 제안된 상호작용법을 AR 주석(Annotation) 시스템에 적용, 구현하여 사용성을 평가하였고, 실험 결과를 통해 제안한 기법의 유용성을 검증하였다. In this paper, we propose a wearable augmented reality system using gaze interaction. Gaze interaction has been considered to be the potential of easy, natural and fast way of interaction and becomes a suitable way in optical see-through HMD based wearable AR. Our system recognizes user's gaze point, half blink motion and displays the information of object seen by user to HMD. Half blink selection technique avoids the Midas touch problem and represents user's intention correctly. We've developed a AR annotation system and estimated the usability of gaze interaction. The accuracy and robustness of our technique is verified on the experimental results.

연쇄살인 범죄자의 유형과 특징

박형민 ( Hyung Min Park ) 대한범죄학회 2012 한국범죄학 Vol.6 No.2

Serial murder falls into one of three categories, ``hedonistic motive type``, ``gaining type``, ``angeres type``. ``hedonistic motive type serial murder`` can be categorized into ``thrill-pursuing type``, ``lust-pursuing type``, ``power-pursuing type``, and ``gaining type serial murder`` into ``burglary-murder type`` and ``crime suppression type``. The serial murders in ``anger type`` can be designated as the repeated ordinary homicide. Serial murderers have a definite motive or specific desire. They select weak victims(elders, women, children, etc.) and suitable time and space for satisfying their desire. Serial murderers take victims as instruments for satisfying their desire. Crimes have developed with time. Type attribute of serial murder is as fallows: ``hedonistic motive type serial murderers`` get an inferiority complex because they had failed to make emotional attachment to other; ``gaining type serial murderers`` have no support system that relieve them.

Purpose Purpose of this study is to know relative relation between Calcium scoring and prevalence rate of Ischemic heart disease, therefore it was divide the dangerous degree, using calcified material Risk classified list in Calcium scoring test. Materials and Methods Chest CT( Cardiac a) underwent from November, 2006 January, 2007. T-score at Calcium scoring examination did 214 (36.58 %) who Test more than 0.1 by target except young child patient, Calcium scoring is a patient who was 0 that have been ever enforced heart and Percutaneous Coronary Intervention(PCI) among 585 patient that is prescribed Chest CT(Cardiac A). Target patient man 115 people (53.7 %), average age 63.2 and woman 99 people(46.3 %), average age 65.8. T-score value that score is gotten by Calcium scoring scan classify, (1)group when it is below 100, 100 to 400 (2)group, and 400 to 1000 (3)group, and more than 1000 to (4)group. And analyzed by back to front about relation of Calcium scoring and ischemic heart disease divides and examined by each LM, LAD, LCX, RCA and compares interpretation sequence with each Coronary arteries T-score value after post enhancement CT scan and find Coronary artery stenosis or Perfusion Defect. Results Calcium score appeared highest by 23,110.5 in LAD and ranged in RCA (18, 996.4), LCX (7, 360.6), LM (3, 412.3) order. Also, when was expose in LAD as Stenosis position distribution chart calcium score’s result, RCA, LCX, LM order and it is 36.6% when is (4)group perfusion defect probability (4)group, and it is 26.3% when is (3)group, it is when is 10% (2)group, it is when is 5.2% (1)group. Conclusion When the Calcium score and ischemic heart disease that analyze data on the basis of diagnostic results, it could know that possibility is high to cause ischemic heart disease, if calcium score was high. Considering these results, position of abnormality or other details information was not agree correctly, It is Calcium scoring scan not only screening test, but also meaning of independent test.

학교평생교육 관점에서 바라본 오산시 혁신교육지구 사업 운영사례와 시사점

최근 들어 공교육 위기를 극복하기 위한 방편으로 학교교육은 폐쇄적 관행을 넘어 지역사회에 손을 내밀고 있다. 혁신교육 운동철학에 바탕을 둔 혁신교육지구 사업은 그 대표적 실천사례이다. 본 연구는 학교평생교육의 관점에서 오산시의 혁신교육지구 사업 운영사례를 조망하고, 해당 사례가 평생교육 영역에 주는 과제와 시사점을 탐색하였다. 이를 위해 연구자는 오산시 혁신교육지구 사업담당자들과의 면담과 관련 자료를 수집하여 분석하였다. 연구결과, 오산시가 참여, 운영하고 있는 혁신교육지구 사업내용의 많은 부분이 학교의 비정규교육과정을 포함한 학교-지역사회구성원을 대상으로 평생학습기회를 제공하기 위한 프로그램으로 구성되어 있었으며, 운영방식 또한 지역사회 인적, 물적 자원의 적극적인 연계를 통해 지역교육공동체를 구축해 나가고 있는 등 학교 평생교육이 지향하는 바와 많은 부분에서 일치하고 있는 특징적 모습을 보였다. 오산시의 사례를 통해 본 연구자는 혁신교육지구 사업을 학교평생교육 활성화를 위한 마중물이라는 인식의 필요성, 혁신교육지구 사업을 포함한 혁신교육 운동에 평생학습도시를 비롯한 지역평생교육 활동 주체들의 적극적 관심과 참여를 통한 학교-지역사회, 학교교육-평생교육의 경계 허물기, 마지막으로 학교평생교육 개념의 확장과 관련 법령의 재정비라는 평생교육영역의 새로운 과제를 도출하였다. This study examined Osan City s cases of innovative education district project operation from the perspective of school lifelong education, and explored the issues and implications on lifelong education. To this end the researcher collected and analyzed interviews and related data from the project managers of Osan City s Innovation Education District. As a result, many of the innovative education district projects that Osan City has participated in and its orientation of operating system was characteristically consistent with school and lifelong education. The case of Osan City suggests that major regional lifelong entities including lifelong learning cities should recognize that the innovative education district project is a precursor for revitalizing school lifelong education, and should actively participate in the innovative education district projects for breaking the boundaries of school-community and school-lifelong education. Finally, it needs to expand the concept of school lifelong education, and rearrange related laws for school lifelong education.

A correlation between the rotating direction and rotation amount according to the eccentricity was analyzed in the present study when fitting the toric soft contact lens. Methods: One hundred fourteen eyes of with-the-rule astigmatism in 20s and 30s were appropriately applied toric soft contact lens by the guideline of manufacturer and fitting evaluations and analyzed the rotating direction and rotation amount when fixating at primary position and 8 different directions of gaze. The speed of reorientation and the correlation between the rotation amount and cornea eccentricity were also analyzed when rotating 45o each toward the temporal and nasal direction. Results: The cornea eccentricity and rotation amount was shown positive correlation. For the gaze of direction, it was identified that the gaze of directions other than the gaze of direction towards the nasal and temporal had correlation, and among them, the gaze of directions to superior and the superior-temporal showed the tendency of decreasing rotation amount as the cornea eccentricity increased. On the contrary, the gaze of direction towards the inferior, inferior-temporal, superior-nasal, and inferior-nasal showed tendency of increasing rotation amount as the cornea eccentricity increased thus, it was identified that the cornea eccentricity showed different correlation according to the gaze of direction. For the case of re-orientational speed, the speed of lens reorientation in the group having the smallest corneal eccentricity was fastest in both direction but was not significantly different. Conclusions: Considering cornea eccentricity to current method of prescribing toric soft contact lens which is based on total astigmatism, it will be helpful to establish the optimal axis stabilization.
