원자력발전소의 정량적 위험성 평가를 위해서 확률론적 안정성 평가 기법이 이용되고 있다. 확률론적 안전성 평가를 수행하기 위해서는 여러 가지 분야의 다양한 신뢰도 데이터가 필요한데, 이를 위한 각종의 신뢰도 자료 중에 인간의 지각 행위 및 수행 행위로부터 발생하는 인적 오류 확률은 그 특성상 실질적이 오류 확률을 얻기가 매우 어렵다. 그래서 인적 오류 확률을 구하기 위해서는 인간 신뢰도 분석분야의 전문가들이 제안한 인간 신뢰도 분석 방법을 이용하여 인적 오류 확률을 추정한다. 한국 원자력 연구소에서는 이를 위해 인간의 지각 및 수행 행위에서 야기되는 인간 오류 사건을 관리하고 인적 오류 확률을 추정하기 위한 인간 신뢰도 분석 시스템을 개발하고 있다. 본 연구에서는 인간 신뢰도 분석 시스템의 개발 과정 및 데이터베이스 설계 그리고 입출력 시스템의 설계에 관하여 기술하였다.

The rapid proliferation of wireless networks and mobile computing applications has changed the landscape of network security. Anomaly detection is a pattern recognition task whose goal is to report the occurrence of abnormal or unknown behavior in a given system being monitored. This paper presents an efficient rough set based anomaly detection method that can effectively identify a group of especially harmful internal masqueraders in cellular mobile networks. Our scheme uses the trace data of wireless application layer by a user as feature value. Based on the feature values, the use pattern of a mobile's user can be captured by rough sets, and the abnormal behavior of the mobile can be also detected effectively by applying a roughness membership function considering weighted feature values. The performance of our scheme is evaluated by a simulation. Simulation results demonstrate that the anomalies are well detected by the method that assigns different weighted values to feature attributes depending on importance.

본연구는 동일실험조건에 의한 한국인과 일본인의 심리적평가, 특히 생활행위로 본 조명환경을 비교한 것이다. 그 결과, 조명환경 평가의 인자구조에는 양국인간의 차이가 없으나, 동일조건에 있어서의 밝기에 대한 감수성은 한국인이 보다 강하다는 사실이 밝혀졌다.

광역도시계획은 전략계획, 정책계획, 지침계획의 성격을 지니는 공간계획으로 청사진 계획으로 운용되어 온 기존의 광역개발계획 및 도시기본계획과 구분된다. 광역도시계획이 정하는 사항은 도시기본계획 및 관련 하위계획에서 기본적 취지를 검토하여 집행됨으로써 이들 계획에 대하여 지침 (guideline)적 성격을 가지나, 직접적으로 개별 개발행위나 토지이용행위를 구속하지는 않는다. 행정중심복합도시 광역도시계획에 대한 전략환경평가는 국토해양부 시행지침에서 제시한 절차를 준용하되, 계획수립 여건을 고려하여 평가계획 수립, 항목과 범위 설정(scoping), 환경성평가, 보고서 작성, 보고서 검토, 모니터링 및 사후평가의 6단계로 진행하였다. 전략환경평가 시 구체적인 항목과 범위, 평가방법 등은 계획의 범위와 성격, 내용 등에 대해 대안의 비교 검토가 가능하도록 4가지 사항을 중점적으로 고려하였다. 즉, 정책목표 달성방법의 환경 적 적정성, 대안의 설정, 자원과 에너지 이용의 효율성, 계획이 지구환경에 미치는 영향 등이다. 계획의 환경성 제고를 위해 설정한 항목은 인구, 토지이용계획, 교통계획, 녹지관리 등 4가지이며, 평가과정에서 반복 및 환류를 통하여 계획과 평가간의 연계성을 도모하였다. 이 과정에서 공간구조 변화는 행정중심복합도시를 정점으로 하고 주변 연결거점을 3개로 늘려 조정하였다.

침입탐지시스템은 침입탐지 기법에 따라 크게 오용탐지시스템과 비정상행위탐지시스템으로 나뉜다. 비정상 행위 탐지시스템은 정상사용행위를 모델링한 후 현재 관찰중인 행위가 정상에서 벗어나는지를 검사한다. 시스템 사용시 발생하는 각 이벤트는 동시에 여러 가지 정보를 담고있으므로 여러 각도에서 모델링될 수 있다. 따라서 여러 결과를 종합해서 판정의 안정성을 높을 수 있다. 본 논문에서는 이벤트의 시스템호출에 평가결과와 BSM감사정보 중 시스템호출관련 정보, 파일 접근관련 정보, 이 둘을 모두 고려한 정보를 통합한 평가결과를 투표방식으로 결합하여 판정하는 기법을 제안하였다. 실험결과 두 모델을 별도로 적용하는 경우보다 나아진 판정성능을 보여주었다.

This study analyzed the effect of metacognition to the information-seeking behaviors of 250 undergraduate students. For this, metacognition was examined by the inspection form that the Educational Psychology Programs of the Department of Education, at Seoul National University, developed in 2005. The information-seeking behaviors were examined by the observance of the established information-seeking performances and through a survey. As a result of the analysis, metacognition affected the items of the survey for the information-seeking behaviors, excluding one item. As metacognition is the cognitive characteristics acting after the cognitive process, it affected thinking activities that were conducted by the brain. In addition, metacognition affected the seeking process, the results of seeking, and the general information-seeking behaviors. Therefore, the study of metacognition is effective in the overall aspects of information-seeking behaviors including the seeking process, the results of seeking, and the general information-seeking behaviors.

The purpose of this study was to identify the changes in the risk factors of metabolic disease by compliance rate and numbers of health behaviors performed in the people who voluntarily participated in the metabolic disease management program implemented in a public health care center. Data were collected from a total of 168 people, January to June of 2015. Data were analyzed by paired t-test and ANOVA with post hoc test. The compliance rates were about 62% and 66% at 3 and 6 months respectively after implementing the program. Although the numbers of health behaviors performed was small, the participants with high compliance rate had significantly lower risk factors of metabolic disease after 6 months. Therefore the compliance rate is critically important to manage metabolic disease and enhancing compliance rate of health behaviors should be developed and investigated in the future studies.

To establish an effective performance appraisal system, ratee accountability is essential because it increases the likelihood of meaningful utilization of performance appraisal feedback. In the context of a multi-rater performance appraisal system, this study examines the effect of the ratee general accountability and accountability to the supervisor and peers on the ratee's intention to change behavior based on the performance appraisal feedback. This study further explored the moderating effect of perceived feedback specificity on the relationship between the ratee accountability and behavioral change intention. Hierarchical multiple regression analysis was conducted using the survey data from 153 employees in eight firms with multi-rater performance appraisal systems. The results showed that ratee general accountability was positively associated with the intention to change behavior. Furthermore, perceived feedback specificity attenuated the positive relationship between the ratee general accountability and behavioral change intention, which was the opposite of the hypothesized direction. The findings indicate the importance of managing and facilitating ratee accountability for implementing a multi-rater performance appraisal system. The result also emphasizes the critical role that performance appraisal feedback plays in motivating performance improvement by providing flexible, constructive advice and behavioral change strategies instead of inducing self-defense or justification.

Intentionality judgement in criminal cases is a core area of fact finding that is root of guilty and sentencing judgment on the defendant. However, the third party is not sure the intentionality because it reflects subjective aspect of agent. Thus, mechanism behind intentionality judgment is an important factor to be properly understood by the academia and the criminal justice system. However, previous studies regarding intentionality judgment models have shown inconsistent results. Mental-state models proposed foreseeability(belief) and desire of agent at the time of the offence as key factors in intentionality judgment. These factors consistent with central things on intentionality judgment in criminal law. However, key factors in moral-evaluation models are blameworthiness of agent and badness of outcome reflected on the consequent aspect of act. Recently, deep-self concordance model emerged suggesting important factors on intentionality judgment are not mental states and moral evaluations but individual's deep-self. However, these models are limited in that they do not consider the important features of criminal cases, that the consequence of the case is inevitably negative, and therefore the actor who is a party to legal punishment rarely expresses his or her mental state at the time of the act. Therefore, this study suggests that, based on the existing intentionality judgment studies and the characteristics of the criminal case, the inference about who the agent was originally will play a key role in judging the intentionality in the criminal case. This is the moral-character model. Futhermore, In this regard, this study discussed what the media and criminal justice institutions should keep in mind and the directions for future research.

This study is to investigate structure relationship between factors influencing or mediating store loyalty in service encounter. The result of study suggests salesperson's voluntary service has an effect on store loyalty through interpersonal relationship and store satisfaction. On the other hand, nonvoluntary service doesn't statistically influence interpersonal relationship but influences store loyalty through store satisfaction. Interestingly this results shows that store loyalty is consisted of cognitive loyalty, affective loyalty, intentional loyalty, and behavioral loyalty and each loyalty have an affect in sequence each other. Managerial implications on research result is followed as first, as an evaluation method of salesperson, it is useful to evaluate salesperson's behavioral performance. second, to build store loyalty, it must make an effort for marketer to differentiate through store promotion in terms of customer's cognitive perspectives. It is meaningful for these results to apply to current retailing situations practically.
