Recently, many studies have been conducted to improve quality by applying machine learning models to semiconductor manufacturing process data. However, in the semiconductor manufacturing process, the ratio of good products is much higher than that of defective products, so the problem of data imbalance is serious in terms of machine learning. In addition, since the number of features of data used in machine learning is very large, it is very important to perform machine learning by extracting only important features from among them to increase accuracy and utilization. This study proposes an anomaly detection methodology that can learn excellently despite data imbalance and high-dimensional characteristics of semiconductor process data. The anomaly detection methodology applies the LIME algorithm after applying the SMOTE method and the RFECV method. The proposed methodology analyzes the classification result of the anomaly classification model, detects the cause of the anomaly, and derives a semiconductor process requiring action. The proposed methodology confirmed applicability and feasibility through application of cases.

The construction industry is considered to be a fatal accident industry, accounting for 28.5% of the total industrial accidents in 2017, as the number of industrial accidents in the construction industry has steadily increased over the past decade. So it is necessary to consider introducing Resilience Engineering, which is actively applied to risky industries around the world, to drastically reduce construction accidents. Although Resilience Engineering, which has emerged as the next-generation safety management centered on Hollnagel since the 2000s, claims the importance of strengthening Resilience abilities considering organizational structure and culture, most studies focus only on developing evaluation indicators. The purpose of this study is to analyze the impact of an organization's safety culture on its Resilience abilities in the construction industry. Specifically, it conducted empirical analysis on the impact of safety culture consisting of ‘communication, leadership and safety systems’ on the Resilience abilities(responding ability, monitoring ability, learning ability, anticipating ability), and the mediation relationship between leadership, communication, and safety system. The survey was conducted on construction workers, and an empirical analysis was conducted on the final 154 responses using SPSS 25 and Smart PLS 3. The results showed that the safety system had a significant impact on all Resilience Abilities, and communication had a significant impact on the remaining three except for anticipating ability among Resilience Abilities. On the other hand, leadership has been shown to have a significant impact on anticipating ability only. In the verifying of the mediation relationship between leadership, communication and safety systems, it was found that leadership affects all Resilience abilities by means of safety systems, but communication can only affect responding ability. This study has practical significance in that it suggests the need for policy-level efforts to introduce and apply Resilience Engineering and then expanded the effective safety management assessment of the construction industry in the future. Moreover, the academic implications are important in that the study attempted to expand the academic scope for a paradigm shift in the future as the safety culture has identified its impact on the Resilience abilities.

목적: 우리나라의 장기기증이나 안구기증은 OECD 국가 중 최하위이다. 세계적인 장기기증 선진국을 보면 장기기증에 대한 교육을 실시하고 있다. 이점을 고려해 볼 때 장기기증에 관한 지식이 기증에 대한 태도나 실천의지에 영향을 미칠 것으로 판단된다. 따라서 본 연구에서는 안구기증에 대한 지식이 안구기증 태도와 실천의지에 어떤 영향을 미치는지 알아 보기 위해 본 연구를 실시하였다. 방법: 본 연구는 대학생 376명(남 163명, 여 213명)에게 안구기증 관련 지식(정의에 관한 핵심지식, 의학적 지식, 법률 및 관리체계에 관한 지식, 현황 및 실태에 관한 지식), 안구 기증 관련 태도(인지적 태도, 정서적 태도, 행동적 태도) 및 안구기증 관련 실천의지에 관한 설문을 조사하고 안구기증 관련 지식이 안구기증 태도나 실천의지에 어떤 영향을 미치는지 분석하였다. 결과: 1. 안구기증 지식 중 '현황과 실태에 관한 지식'이 가장 점수가 높았다. 2. 성별에 따른 안구기증 지식은‘현황 및 실태에 관한 지식’만이 남자가 유의하게 높았다. 3. 안구 기증 태도 중 행동적 태도는 종교와 통계적으로 유의하게 관계가 있었다. 4. 안구기증 관련 교육 경험이 있는 학생의 안구기증에 대한 인지적 태도와 행동적 태도에 대한 점수가 통계적으로 유의하게 높았다. 5.안구기증 지식 중 의학적 지식만이 전체 태도와 유의하게 연관이 있었다. 6. 안구기증 지식 중 ‘핵심지식’과 ‘현황 및 실태지식’은 안구기증 실천의지와 유의하게 연관이 있었다. 결론: 안구기증 관련 교육 경험은 안구기증 태도와 유의한 상관관계가 있으며 안구기증 지식 중 ‘핵심지식’과 ‘현황 및 실태지식’은 안구기증의 실천의지와 유의한 상관관계가 있으므로 안구기증 문화의 정착을 위해서는 안구기증에 관한 교육이 효과가 있을 것으로 판단된다.
