최근 우리나라에서 빈번하게 발생되는 가뭄으로 인하여 많은 피해가 발생하고 있으며, 이에 대한 사전대응의 필요성이 커지고 있다. 가뭄에 대한 효과적인 사전대응을 위해서는 신뢰성 있는 가뭄 예측 정보가 필수적이다. 본 연구에서는 수문학적 가뭄에 대한 확률론적 예측을 수행하기 위하여 가뭄의 전이현상을 베이지안 네트워크 모형에 반영하였다. 가뭄의 전이현상을 고려한 베이지안 네트워크 기반의 가뭄 예측 모형(PBNDF)은 과거, 현재, 미래에 대한 다중 모형 앙상블 예측결과와 가뭄전이 관계를 결합하여 새로운 수문학적 가뭄 예측 결과를 생산하도록 구축되었다. 본 연구에서 PBNDF 모형은 파머수문학적 가뭄지수를 활용하여 낙동강 유역의 10개 지점을 대상으로 가뭄을 확률적으로 예측하는데 적용되었다. PBNDF 모형의 ROC 분석 결과 ROC 점수가 0.5 이상의 유의한 결과를 나타내 실제 예측 모형으로 활용가능하다는 것을 확인할 수 있었다. 또한, 기존에 개발된 모형(지속성 예측, 베이지안 네트워크 예측 모형)과 평균제곱오차의 제곱근(RMSE), 기술 점수(SS)를 활용하여 비교를 수행하였으며, 그 결과 PBNDF 모형의 RMSE는 상대적으로 낮은 값을 가지며, SS는 약 0.1~0.15 정도 높은 것으로 나타나 예측성능이 향상되었다는 것을 확인할 수 있었다.

Purpose: This study investigated the effectiveness of simulation training with a hybrid model of student nurses' performance ability and reported self confidence. Methods: A nonequivalent control group with pre-posttest was designed. Data collection was done during the first semester in 2012 at a college of nursing in Seoul. Nursing performance ability and reported self confidence related to taking care of patients with urinary problems were evaluated. The treatment group (n=96) received simulation training of a catheterization procedure with a hybrid model involving standardized patients and a mannequin. Nursing students in the comparison group (n=84) did not receive the simulation training but would receive it prior to their next clinical practicum's. Results: The treatment group showed a significantly higher performance ability and reported self confidence than that of the comparison group. The perceived helpfulness and contentment of the simulation training in experimental group was high. Conclusion: The findings of this study demonstrated that simulation with a hybrid model was effective in teaching skills prior to the clinical experience which suggests that skill development is not dependent on the actual clinical situation. Nurse educators should consider simulation training as a tool beyond that of clinical practicum.

In a large number of literature on of inspection tasks, one of the most consistent findings is the existence of large and consistent differences among inspectors. It is possible that the individual difference is described by the difference of cognitive skills, because cognitive skills are required more than manual skills in inspection tasks. Therefore, a set of cognitive factors in human information processing may underly human performance in inspection tasks. In this study, a cognitive skill was described as the relative importance of the cognitive factors involved. A hierarchical task analysis and a fuzzy hierarchical analysis were used to represent how the importance of cognitive factors contribute to inspection performance. An experiment was conducted using the computer simulations of PCB inspection tasks. The results revealed that the subject group with better performance showed the importance weights of cognitive factors in the following rank; (attention, perception, judgement, classification, recognition)<(detection)$\ll$(memory). The results of the experiment can serve as a selection criterion for efficient inspection performance and the information of skilled learning for an inspection training program. The usefullness of a hierarchical task analysis and a fuzzy hierarchical task analysis for the analysis of cognitive tasks are also confirmed.

The purpose of this study is to analyze the trend of the prize money and the performance factors, based on the data of 1,000 pro golf players provided by KLPGA(Korea Ladies Professional Golf Association) for the past 10 years from 2008 to 2017. First, in terms of the prize money, it increased a lot if we compare the data from 2008 and from 2017. However, it is still disproportionally favorable to the top players and is extremely disadvantageous to the middle-low players. Therefore, it is necessary to considerately care middle-low players. Second, in terms of performance factors, the players' skill has been improved steadily based on all of the factors considered: the scoring average, average putting, the birdie average, par save, par break, and recovery for the past 10 years from 2008 to 2017. Despite the fact that both players' performance and income have increased, it is prominent that the inequality between the players in terms of prize money becomes severe, which should be mitigated by external systematic support to maintain the current level of world-class players of Korea.

Due to recent enhance of safety law and regulations in construction sites, safety inspectors have been more required in construction sites. However, most of them are novice for safety inspection which have not enough experience and skill. Therefore, the novice safety inspector's performance on hazard recognition needs to be improved for effective safety management. The performance of safety inspection is influenced by the inspector's experience and background because the inspection is usually conducted by the inspector's eyes. Therefore, there is a difference in safety inspection performance between novice and experienced safety managers. This study aims to analyze the gap of risk perception between novice and experienced safety managers using quantitative visual data. For this objective, this study conducted eye tracking experiments for novice and experienced group to evaluate cognitive performance of safety risk factors. The results provides the level of safety awareness based on their experience in construction safety. The limitation of this study is a lack of the number of samples used in this study and did not consider the various characteristics of the participants. If these limitations are supplemented in future research, it can be used to develop safety education contents for novice safety managers.
