연구목적 : 전산화 Standard Progressive Matrices(SPM) 검사의 한국인 성인 표준자료를 확립함으로써, 간이로 지능을 평가하는 경우에도 보다 정확하게 지능지수를 추정하기 위해서 본 연구를 수행하였다. 방 법 : 18세 이상의 남녀 정상인 자원자 353명을 대상으로 전산화 SPM 검사를 시행하고, 백분율 및 표준점수(T-점수)를 기준으로 하여 표준화 자료를 작성하였다. 전체 대상군을 성별, 연령별로 구분한 후 평균과·분포가 유사한 집단은 군을 합치는 방법을 사용하였다. 한국인 표준자료에 근거하여 추정한 SPM 지능지수와 외국인 표준자료에 근거하여 추정한 SPM 지능지수를 각각 KWAIS 지능지수와 비교함으로써 타당도를 검증하였다. 결 과 : 18∼30세, 31∼40세, 41∼50세, 51세 이상의 연령군으로 구분된 한국 정상 성인의 SPM 표준화 자료를 산출하였다. 본 연구 결과에 의한 표준화 자료를 적용하여 지능지수를 추정하는 것이 현재 사용하고 있는 외국인의 표준화 자료를 이용하는 것보다 KWAIS 지능지수에 더욱 근접한 결과를 보였다. 결 론 : 18세에서 50세까지의 한국인 남녀에게는 간이지능평가도구로서 전산화 SPM 검사의 한국인 표준화 자료를 유용하고 타당하게 적용할 수 있음을 확인하였다. Objectives : We conducted this study to provide standardized data of the computerized Standard Progressive Matrices(SPM) test in Korean adults. Methods : The computerized SPM test was administered to 353 healthy volunteers aged 18 years over. We provided the standardized data(percentile and standardized T-scores) for the groups with similar mean and distribution of SPM scores, which was originally divided by age and sex. The validity of the new standardized data was tested by comparing IQs estimated by SPM and K-WAIS. Results : The standardized SPM data were provided for four age groups : 18 to 30 years, 31 to 40 years, 41 to 50 years, 51 years and over. IQ estimated by this standardized data tends to be closer to IQ by K-WAIS than the IQ estimated by foreign normative data. Conclusion : The standardized data of the computerized SPM were proven to be a useful and valid tool for measuring IQ briefly, compared with the conventional way of measuring IQ.

The issue of historic preservation and restoration held no interests for the architects who pioneered and developed the modern movement. To them, the architectural theory of the modern movement was useful precisely because it helped them to break free of the historical past and the theoretical tradition of earlier architecture. In our own time, however, historic preservation has become multifaceted and the area of its involvement is constantly changed, and it has assumed almost as great an urgency as the continued development of modernity. As it has broadened its areas of activity and architect has played an important role in shaping the past and present of historic preservation and restoration, preservation research should focus its priorities and understand the limits of its resources in historic preservation and restoration process. In this study, therefore, the preservation and restoration principle of the 19th century European architects which were the main stream of historic preservation and restoration movement, was investigated from comparing there works and theories.

연 x-선 현미경은 ‘물의 창’ 영역(2.3~4.4 nm)의 파장을 이용하여, 수십 nm의 분해능으로 세포를 파괴하지 않고 살아있는 상태에서 세포의 내부구조를 관찰할 수 있어 가시광선현미경과 전자현미경을 단점을 보완하는 특징을 갖는 세포 생물학 연구에 적합한 현미경이다. 그러나 기존 연 x-선 현미경은 광원으로 방사선 가속기를 이용하기 때문에 사용이 제한적이었다. 이에, 본 연구에서는 2.88 nm의 연 x-선을 광원으로 사용하는 소형 연 x-선 현미경을 이용하여, 내포작용에 의해 금 나노입자를 포획한 HT1080과 MDA-MB 231 세포의 영상을 약 60 nm 분해능으로 획득하였다. 금 나노입자의 세포에 대한 독성을 제거하기 위하여 폴리에틸렌 글리콜을 캡핑하였고, 2.88 nm 파장의 연 x-선에 대하여 충분한 조영효과로 인하여 세포영상에서 뚜렷한 대조도를 나타내었다. 내포작용에 의해 액포에 포함되어 있는 다양한 크기의 금 나노입자 군집을 확인하였으며, 세포내부의 액포의 분포상태도 관찰할 수 있었다. 따라서 고분해능을 가진 소형 연 x-선 현미경을 이용하여 금 나노입자를 세포내의 미세기관이나 특정 단백질에 표지하면 연 x-선에 대한 조영효과의 증가에 의하여 더욱 유용한 정보를 획득할 수 있을 것으로 생각한다. A compact soft x-ray microscope operated in the ‘water window’ wavelength region (2.3~4.4 nm) was used for observing cells with nano-scale spatial resolution. To obtain cellular imaging captured with colloidal gold nanoparticles using a compact soft x-ray microscope. The colloidal gold nanoparticles showed higher contrast and lower transmission more than 7 times than that of cellular protein on the soft x-ray wavelength region. The structure and thickness of the cell membrane of the Coscinodiscus oculoides (diatome) and red blood cells were seen clearly. The gold nanoparticles within the HT1080 and MDA-MB 231 cells were seen clearly on the soft x-ray microscopy. The gold nanoparticles were aggregated within vesicles by endocytosis.

To study the good movement state of the trunk twisting and the segment of the upper limbs to get the correct logn throwing distance, the author got the kinematic changing elements of the upper limbs movement by the screen analysis of the displacement, and the movement velocity of joints, angles of joints, spending hours, and the wheel tracks, selecting the skilled and the unskilled. 1. In the throwing at his position, when the trunk twisting was great, the shifting distance of the joints was longer, and had the natural track in which ending was gentle. 2. The vertical movement of the body had a deep relation with the trunk twisting in the throwing movement. 3. When the trunk twisting was very slow, the direction of the joint track was direct opposite to the quick twisting. 4. The time each track got out of the body and the shifting distance of the slowest joint velocity by the trunk twisting of the skilled, vertical shift, and the enlargement of the angle of joints coincided. 5. The spending hours of the throwing movement became longer as the trunk twisting was big, and the slowest joint velocity which preparing time is ended in the throwing movement was in the position around 60% of the total spending hours. 6. In the skilled person the appearing of the slowest velocity of each joints coincided among joints, and brought the late half velocity rising at the slower velocity (skilled : 5m/sec, unskilled : 9m/sec) comparing the unskilled person. 7. The time of the late half velocity rising and shifting distance had a deep relation with the velocity of a ball when it was released.

6·13 지방선거에 대한 유권자 의식과 평가 : 대구·경산지역의 설문조사를 중심으로

박성만,장성익,정진홍,권윤희 大邱大學校 社會科學硏究所 2002 社會科學硏究 Vol.10 No.1

이번 민선3기 지방선거는 여느 때와 달리 월드컵이라는 국제행사와 맞물려 유권자들의 투표율이 50%미만으로 관심이 매우 저조하였고, 지방선거에 대한 비관론이 대두되고 있는 가운데 바람직한 선거문화정착과 바람직한 후보자를 결정하는 것은 지방자치발전의 중요한 과제라 할 수 있다. 이러한 의미에서 본 연구는 6.13지방선거에 대한 유권자들의 의식을 평가하고 향후 지방선거의 발전성향을 제시하고자 하였다. 이를 이해 본 연구는 이번 2002년 6월 13일 실시된 지방선거에 관한 유권자들의 의식을 질문지를 통해 조사하고 분석하였다. 분석결과 이번 6.13 지방선거에 대한 유권자들의 의식은 전체적으로 지방정치와 지방선거 관심이 저조한 것으로 나타났으며, 이러한 원인은 여러 가지로 분석할 수 있으나 유권자의 무관심과 후보자들의 자질, 여러 가지 상황적 변수들이 복합적으로 나타난 결과라 할 수 있다. 유권자들의 선거에 대한 태도는 과거 여느때 보다 소극적이었으며, 결정시기와 결정방법에 있어서도 적극적인 참여가 부족하였다. 또한 6.13지방선거에서의 전체적인 유권자의 만족도는 낮게 나타났으며, 선거의 공정성, 주민참여정도, 법규준수정도, 관건개입정도는 지난 지방선거과 비교하여 낮거나 보통인 것으로 나타났다. 이는 지방선거에 대한 중요성을 일반 유권자들이 인식하지 못하고 있는 것으로 생각된다. 또한 지방선거에서의 문제점의 하나로 드러난 월드컵이라는 국제적 행사와 겹쳐 선거의 소홀로 나타난 지방정치에 대한 무관심은 앞으로 선거일정을 조정하는데 하나의 시준점을 삼아야 할 것이다.
