This study was concerned with the investigation of the relationship between the degree of family incongruence about family environment and the occurrence of juvenile delinquency using Family Environmental Scale (F.E.S) designed by Rudolf Moos. The study employed the control group design using the interview and questionnaire through home visiting. The control group sample consisted of 44 families from a middle socioeconomic S Dong community setting and the experimental group sample consisted of 30 families of juve nile from Juvenile Training School in Seoul, Total sample size was 321. Data for this study was collected over a period of three months from the end of Nov. 1982 to the beginning of Feb. 1983, after pretest. To analize the data, t-test was used. The result of this study was as follows; 1. The experimental groups' incongruence score was 18.8598 as compared to the control groups' score of 14.8598. The differences were statistically significant at .001 level, and the hygothesis was supported. 2. The experimental group had higher incongruence scores as compared to the control group of three dimensions, the differences were statistically significant at .05 level. The experimental group had higher incongruence scores than the control group on 6 subscales, namely, cohesion, expressiveness, conflict, achievement orientation, moral-religious emphasis and organization. The differences were statistically significant at. 05 level.

This study aims to explore factors of Assimilation Gap(AG) which is proposed and illustrated by Fichman and Kemerer(1997). AG is defined as the time delay between adoption and deployment and mainly studied at the organizational level. This study derives the factor affecting AG through a review of technology acceptance models and agency theory. The research model consists of three groups of independent variables(IT knowledge burden, Individual characteristics, and organization characteristics) and a moderator, which is goal incongruence. Using multiple regression analyses, four groups of hypotheses are tested with data of 221 knowledge workers from various organizations through e-mail survey. The result shows that radicalness(a dimension of knowledge burden), personal innovativeness, self-efficacy, and organizational support are statistically significant factors while complexity, experience, and perceived critical mass are not supported. The moderator effects of goal incongruence are found in personal innovativeness and organizational support. The results of this study demonstrate that agency theory is a useful perspective to deal with AG, especially in radical innovation. In addition, IT practitioners should consider not only user training but also incentives and possible organizational controls in implementing a new information technology.

본 연구에서는 정서를 두 양상(청각, 시각)으로 제시할 시, 두 양상의 정서가 일치 혹은 불일치 할 경우 각성과 재인 기억, 회상 기억에 영향을 미친다는 것을 알아보고자 하였다. 본 연구의 첫 번째 가설은 교차 양상에서의 정서 불일치는 일치 할 때 보다 각성 뿐만 아니라 재인, 회상 기억 모두 높을 것이라는 것이다. 두 번째 가설은 각성이 회상 기억과 재인 기억을 modulate한다는 것이다. 가설을 증명하기 위해 시각과 청각의 정서를 긍정 정서와 부정 정서로 조작하여 일치 조건과 불일치 조건으로 조작하였다. 각 조건에서는 재인 기억과제와 회상 기억 과제의 정확도를 종속 변인으로 측정하였으며, PAD(Pleasure-arousal-dominance) 척도를 이용하여 참가자의 각성 수준을 측정하였다. 또한 8일이 지난 후, 참가자 모두에게 실험 자극으로 쓰인 영상에 대해 재인 기억 과제를 통해 다시 검사하였다. 연구 결과, 각성의 경우 영상을 본 후의 각성 차이는 통계적으로 유의미하게 나타났지만(p<.001), 일치와 불일치 조건 간의 각성 차이는 나타나지 않았다. 또한 정서가 일치하는 조건과 불일치하는 조건에서 재인 기억이 통계적으로 유의미하지는 않았지만, 영상 정서의 주 효과가 통계적으로 유의미하게 나타났다. 이로 인해 두 가지 정서로 나누어 분석한 결과, 부정 정서 영상에 노출된 조건에서만 일치 조건과 불일치 조건에서의 재인 기억이 통계적으로 유의미한 차이를 보였다(p= .044). 사후 분석 결과, 불일치 조건에서 일치 조건 보다 높은 점수를 보였다. 회상 기억의 경우, 영상 정서조건과 일치, 불일치 조건 간의 상호작용이 나타났다(p=.039). 따라서 본 연구에서는 부정 정서에서의 불일치 효과는 증명하였지만, 각성으로 인한 효과는 증명하지 못하였다.

본 논문에서는 시각에 대해 반응하는 운동 행동의 효과를 분석하기 위해서 응답속도정합-유발전위(RTA-ERP: Response Time Aligned-Event Related Potential)를 모델링하고, RTA-ERP의 진폭과 응답 속도를 이용하여 사이먼 효과를 분석하였다. 건강한 성인 15명(남성 9명, 여성 6명, 평균 연령 31세)을 대상으로, 같은 숫자에 대한 다른 숫자를 찾아 반응하는 '양자극방안' 실험을 7분 동안 수행하였다. 실험결과 제안된 RTA-ERP는 기존의 ERP에 비해 뇌에서의 처리시간 차이에 따른 변이를 보상할 수 있었으며, 향상된 LRP(Lateralized Readiness Potential)와 Pe(Error Related Positivity)를 나타내었다. '일치', '불일치' 시험 패턴에 대하여 '일치'에 대한 RTA-ERP의 진폭과 응답속도는 각각 '불일치'보다 컸으며 진폭은 $0.03{\mu}V$ 크고 반응속도는 43 ms 만큼 빨랐다. 응답속도에 따른 동기 시점을 보정하여 정합함에 따라, RTA-ERP의 진폭특성은 사이먼 효과의 특징인 ERP의 P300 진폭과 대응함을 확인하였다.

Purpose : To evaluate the usefulness of the reconstructed 3-dimensional image on the personal computer in comparison with that of the CT workstation by quantitative comparison and analysis. Materials and Methods : The spiral CT data obtained from 27 persons were transferred from the CT workstation to a personal computer, and they were reconstructed as 3-dimensional image on the personal computer using V-works 2.0/sup TM/. One observer obtained the 14 measurements on the reconstructed 3-dimensional image on both the CT workstation and the personal computer. Paired Nest was used to evaluate the intraobserver difference and the mean value of the each measurement on the CT workstation and the personal computer. Pearson correlation analysis and % incongruence were also performed. Results: I-Gn, N-Gn, N-A, N-Ns, B-A, and G-Op did not show any statistically significant difference (p>0.05), B-O, B-N, Eu-Eu, Zy-Zy, Biw, D-D, Orbrd R, and L had statistically significant difference (p<0.05), but the mean values of the differences of all measurements were below 2 mm, except for D-D. The value of correlation coefficient y was greater than 0.95 at I-Gn, N-Gn, N-A, N-Ns, B-A, B-N, G-Op, Eu-Eu, Zy-Zy, and Biw, and it was 0.75 at B-O, 0.78 at D-D, and 0.82 at both Orbrd Rand L. The % incongruence was below 4% at I-Gn, N-Gn, N-A, N-Ns, B-A, B-N, G-Op, Eu-Eu, Zy-Zy, and Biw, and 7.18%, 10.78%, 4.97%, 5.89% at B-O, D-D, Orbrd Rand L respectively. Conclusion : It can be considered that the utilization of the personal computer has great usefulness in reconstruction of the 3-dimensional image when it comes to the economics, accessibility and convenience, except for thin bones and the landmarks which are difficult to be located.

To elucidate the molecular phylogeny of Neottia japonica, which is a terrestrial orchid distributed in East Asia, the internal transcribed spacer (ITS) of nuclear DNA and the matK of chloroplast DNA were used. A total 22 species of 69 accessions for ITS and 21 species of 114 accessions for matK phylogeny were analyzed with the maximum parsimony and Bayesian methods. In addition, we sought to establish a correlation between the distribution, morphology of the auricles and genetic association of N. japonica with phylogenetic data. The phylogenetic results suggest that N. japonica is monophyletic and a sister to N. suzukii in terms of the ITS phylogeny, while it is paraphyletic with N. suzukii in terms of the matK phylogeny. N. japonica and N. suzukii show similar morphologies of the lip and column, they both flower in April, and they are both distributed sympatrically in Taiwan. Therefore, it appears to be clear that N. japonica and N. suzukii are close taxa within Neottia, although there is incongruence between the nrDNA and cpDNA phylogenies of N. japonica. The incongruence between the two datasets may have various causes, meaning that further studies are needed to confirm the evolutionary process of N. japonica. The phylogenetic status of N. kiusiana, which was not included in previous studies, was as a sister to N. nidus-avis. Meanwhile, the ITS and matK phylogenies are unsuitable for identifying genetic associations with the characteristic of auricles. The phylogenetic topologies of Korean, Taiwanese and mainland Chinese individuals suggest that the populations of N. japonica in Korea originated from China's mainland and island areas. The characterization of regional gene differences could provide useful preliminary data for future studies.

Recently, the industrialized world is suffering from accidents referring from the lack of safety consciousness. According to Korean Safety Regulation Department(1996), students at junior high schools are mostly involved in safety accidents, and this is due to lack of safety consciousness. To prevent these accidents, we need to have safety consciousness and attitude. To make junior high school students who are mostly affected in these accidents act safely, they need to know their level of safety consciousness. The purpose of this study is to develop a guideline of measuring the scale of safety consciousness and analyze the relationship between safety education, accident experiences and safety consciousness. This study is based on a survey of 708 junior high students in Seoul, which was carried out from 12 November, 2001 to 21 November, 2001. 1. The main fields of safety consciousness are home safety, school safety, fire safety, emergency management based on documents. Home safety is again divided into facility safety and livelihood safety, school safety is divided into facility safety, livelihood safety and laboratory safety, traffic safety is divided into pedestrian safety, bicycling safety and public transportation safety, fire safety divided into prevention and escaping during fire breakouts, emergency management safety is divided into general principles and escaping during emergency situations. 2. The primary safety consciousness scale was made according to every field of safety consciousness. A preliminary examination based on the scale and a study of reliance and the factors was held. Based on these results, 27 questions which were concerned to be impairing reliability or lacking in factor were deleted on the secondary safety consciousness scale development The secondary safety consciousness scale which constituted of 73 questions was put into another preliminary study and after analyzing reliability and the factors, 12 questions of low reliabilities were deleted and with these results, the third scale were made consisting of 61 questions. 3. A study based on the third safety scale which is made of 61 questions, were held and with a analysis of the reliability and factors made, the relationship between safety education, accident experience and safety mind were examined. (1) The study of reliability and factors show that Cronbach's coefficient in home safety fields is .7598, in school safety .7924, in traffic safety .8306, in emergency treatment .7775, in fire safety .7247. The questions indicating low reliability were deleted. The factor analysis revealed that home safety is converged on facility safety and livelihood safety. But one question was deleted because it showed incongruence of validity. School safety was converged on facility safety, livelihood safety and laboratory safety. But 2 questions showed incongruence of validity and these were deleted. Traffic safety fields were converged on pedestrian safety, bicycle safety and public transportation safety. One question showing incongruence of validity was deleted. Emergency treatment fields converged on general principles and acting in emergency situations and three questions showing incongruence of validity were deleted. Fire safety was converged on prevention and acting in fire breakouts. Totally, eight questions were removed and the final scale were consisted of 53 questions (2) The 3/sup rd/ grade students scored higher average safety mind scales than 1st graders(p〈.05). And students who had high scores at school tend to have a higher scale than those who do not(p〈.001). (3) Average scale of students who had experience in safety education were higher(p〈.001). Students who had previously been involved in home safety accidents had a low score(p〈.001). This was same to students with experience in school safety accidents(p〈.001). Students with traffic safety accidents and fire safety accidents tend to have a lower scale too(p〈.05, p〈.001).
