In this paper, we investigate the notion of error correction memory applied to technical texts. The main purpose is to introduce flexibility and context sensitivity in the detection and the correction of errors related to Constrained Natural Language (CNL) principles. This is realized by enhancing error detection paired with relatively generic correction patterns and contextual correction recommendations. Patterns are induced from previous corrections made by technical writers for a given type of text. The impact of such an error correction memory is also investigated from the point of view of the technical writer's cognitive activity. The notion of error correction memory is developed within the framework of the LELIE project an experiment is carried out on the case of fuzzy lexical items and negation, which are both major problems in technical writing. Language processing and knowledge representation aspects are developed together with evaluation directions.

When an accident occurs, the associated human activity is typically regarded as a "human error," or a temporal deviation. On the other hand, if the accident results in a serious loss or if it evokes a social issue, the person determined to be responsible may be punished with a "violation" of related laws or regulations. However, as Heinrich stated, it is neither appropriate nor reasonable in terms of probability theory and cognitive science to distinguish whether it is a "human error" or a "violation" with a criterion of resultant accident severity. Nonetheless, some in society get on the social climate to strengthen regulations on workers who have caused accidents, especially violations. This response can present a social issue due to the lack of systematic judgment procedure which distinguishes violations from human errors. The purpose of this study was to develop an objective and systematic procedure to assess whether workers' activities which induced industrial accidents should be categorized as violations rather than human errors. Various analysis techniques for the determination of violation procedure were investigated and compared using an analysis approach method. An appropriate technique was not found, however, for judging the culpability of intentional violations. As an alternative, this study developed the process of creating violations, based on cognitive procedure, as well as the criteria to determine and categorize an activity as a violation. In addition, the developed procedure was applied to cases of industrial accidents and nuclear power plant issues to test its practical applicability. The study demonstrated that the proposed model could be used to determine the existence of a violation even in the case of multiple workers who work simultaneously.

In Korean society, the theme of human errors in railway has been emerging as a critical issue. As far as human error studies are concerned, main trend has been inclined to be led by industrial engineering and systems science. Apart from those trends, this study empirically highlighted the relationship between depression, which has been a frequent research subject in the medical science and psychology, and accidents, with setting depression as an exogenous variable and cognitive failure and mistake as endogenous variables, respectively. Results of hypotheses test for the 204 respondents showed that driver's depression has a significant effect on accidents mediated by cognitive failure and mistake. This findings suggest the need for exploring the diverse latent factors causing human errors and for understanding the complex cognitive process as well as for establishing integrative countermeasures to mitigate human errors.

Traffic signs without a cognitive consideration in their design may cause information-processing problem that could result in a mental confusion among drivers often lead to a serious traffic accident. Therefore, in this study, several traffic signs currently used in Seoul Metropolitan area have been sampled and analyzed to identify design problems that usually caused by neglecting drivers cognitive ability. To classify the practical design problems, five major information-processing problems have been suggested: indistinguishable information, information conflict, missing information, sign-load mismatch, and information overload. In order to solve these cognitive problems, new traffic signs have been suggested in this study. An experiment was also performed to validate the new traffic sign. Twenty-four healthy subjects participated in the experiment. They were asked to answer the Question after observing the traffic signs continuously displayed on computer screen. The result indicated that subjects improved the accuracy in understanding the signs by 1.4 times when they used the suggested traffic sign compared to the old one. Based upon the results, a cognitive guideline was suggested for correct and speedy reading of traffic signs by improving information processing and reducing of human error. In conclusion, the traffic sign may well be applied to design an intelligent traffic sign system to increase the safety and comfort of drivers, especially in complex load condition.

본 연구는 도박자와 비도박자를 대상으로 비합리적 도박신념과 도박행동의 관련성을 확인하고, 기존 연구들이 직접 다루지 않았던 인지적 오류로서 확률적 사고 오류, 귀인양식 및 귀인편향성이 도박행동에 관련되는지에 대해 알아보았다. 248명의 자료를 수집하여 비(非)도박자, 경(經)도박자, 중(重)도박자로 구분하고, 비합리적 도박신념, 확률추론 오류, 귀인양식 및 귀인편향성을 비교하였다. 비합리적 도박신념은 비도박자<경도박자<중도박자 순으로 높게 나타났는데, 하위요인으로서 자기과신적 추론에서 유의미한 차이를 보였고 기술과대평가적 추론에서는 통계적으로 유의한 차이없이 세 집단이 모두 척도평균(4점) 이상의 높은 신념을 형성하고 있었다. 또한, 비도박자에 비해 경도박자와 중도박자의 확률추론 오류 정도가 높았다. 중도박자들은 비도박자와 경도박자에 비해 일상적 사건에 대해 외부귀인 정도가 높고 내부귀인 정도는 낮으며 실패상황에 대한 내부귀인 편향성이 높은 것으로 드러나, 중도박자 집단과 경도박자, 비도박자 간 구분되는 인지적 오류 특성들이 확인되었다. 도박여부를 예측하는 선행요인들의 상대적 영향력을 검증한 결과 실패에 대한 내부귀인 편향성, 확률추론 오류, 비합리적 도박신념 중 자기과신적 추론, 일상사에 대한 외부귀인 성향 순으로 도박행동 예측력이 높게 나타났다. 본 연구를 통해 도박자와 비도박자의 인지적 오류 및 편향성에 어떤 차이가 있는지 확인함으로써, 도박자 뿐 아니라 도박을 하지 않는 일반인을 대상으로 도박에 관한 지속적인 홍보와 사회교육의 필요성을 제안하였다.

Objective : The purpose of this study is to examine relationship between cognitive function and sasang constitution by analyzing EEG status of company workers in Cheon-An. Method : 59 company workers were tested with cognitive assessment EEG program and questionaire for the Sasang Constitution Classification II. They were assorted by Sasang Constitutions, and we analyzed its correlation with cognitive assessment score and EEG data. Results : 1. According to mean active EEG rhythm of Alpha. H-Beta, Gamma wave, there were no significant difference among Sasang Constitution. 2. According to mean success, error, concentration, response, workload and left/right brain activity score, there were no significant difference among Sasang Constitution. 3. According to mean active EEG rhythm of Theta, SMR, M-Beta wave, Soyangin(少陽人)'s value was significantly higher than that of Taeumin(太陰人) 4. According to mean cognitive strenghth score, Soyangin(少陽人)'s value was significantly higher than that of Taeumin(太陰人). Conclusion : In conclusion, Sasang Constitutional difference has no relevance with cognitive abilities However, Soyangin(少陽人) showed higher mean active EEG rhythm of Theta, SMR, M-Beta wave than that of Taeumin(太陰人). In addition, Soyangin(少陽人) also showed higher mean cognitive strenghth score than that of Taeumin(太陰人).

이 연구는 학생들에게 예상과 불일치한 실험 데이터를 제시한 뒤, 학생들이 이 데이터를 어떻게 해석하는가를 알아보는 것이다. P 대학교 대학생을 대상으로, 진자의 주기에 대해서 과학적 개념을 가지고 있는 학생 중, 깡통진자에 물을 넣어가면서 깡통진자의 주기를 측정할 때, 주기가 일정할 것이라고 예상한 학생 45명을 선발하였다. 학생들에게 깡통진자에 물을 넣어가면서 주기를 측정한 데이터를 제시하고, 표에 기록하게하고 그것을 그래프로 그려 자료변환을 하도록 하였다. 검사문항지를 통해 불일치 인식, 데이터에 대한 선뢰, 인지갈등, 개념 변화 및 실험 결과에 대한 가설 등을 조사하였다. 인지 갈등정도를 측정하기 위해 CCLT(Cognitive Conflict Levels Test) 검사문항지를 사용하였다. 일부 학생들은 선개념에 의존하여, 데이터를 실제 데이터가 아니라고 간주하거나 실험 오류로 간주하였다. 불일치 상황을 인식 한 학생들은 그렇지 않은 학생들에 비해 인지갈등 정도가 높았다. 선개념에 대한 신념이 변한 학생들은 불일치 상황을 인식하였고, 신념이 변하지 않은 학생들에 비해 인지갈등 정도가 높았다. 선개념에 대한 신념이 변하지 않은 학생들은 데이터를 실험 오류로 간주하였다.

A sequential optimization algorithm (SOA) for resource allocation in a cyclic-prefixed single-carrier cognitive relay system is proposed in this study. Both subcarrier pairing (SP) and power allocation are performed subject to a primary user interference constraint to minimize the mean squared error of frequency-domain equalization at the secondary destination receiver. Under uniform power allocation at the secondary source and optimal power allocation at the secondary relay, the ordered SP is proven to be asymptotically optimal in maximizing the matched filter bound on the signal-to-interference-plus-noise ratio. SOA implements the ordered SP before power allocation optimization by decoupling the ordered SP from the power allocation. Simulation results show that SOA can optimize resource allocation efficiently by significantly reducing complexity.
