Background: This study aimed to evaluate the relationship between clinical experience and death certificate (DC) errors by analyzing DCs written by experienced emergency physicians (EPs). Methods: DCs issued by four experienced EPs over a 10-year period were retrospectively reviewed. DC errors were divided into major and minor errors based on whether they affected the cause of death (COD) determination. The errors were judged through first and second evaluations. Basic information regarding DCs and 10-year changes in DC errors were analyzed. Results: A total of 505 DCs were analyzed, with an average of 34 to 70 for each study year. The number of CODs written in the DCs tended to decrease over time. The presentation of major DC errors did not show a tendency to change over time. However, the sum of the major and minor errors tended to increase over time. Secondary conditions as the underlying COD tended to increase, and the incompatible causal relationships between CODs tended to decrease over time in the detailed analysis of major errors. The increasing tendency for incorrect other significant conditions, incorrect type of accident, incorrect intention of the external cause, no record of the trauma mechanism, and record of the trauma mechanism without another COD were found in the detailed analysis of minor errors. Conclusion: DC errors did not decrease as clinical experience increased. Education to reduce DC errors and a feedback process for written DCs are necessary, regardless of clinical experience.

Recently, plastic panels have replaced plywood panels in formwork. Since, plastic panels have excellent workability, can be re-used for over 50 times, and are lighter than Plywood. This paper aims to perform an economic analysis of plastic panels by considering unit cost, cost of form oil and the number of use. The results showed that plastic panels are more economical than plywood according to an increase in area of construction site. This result of the study can be used as a basic data for the selection of plastic formwork panels.

패턴 쌍을 기억할 수 있는 신경망, BAM(Bidirectional Associative Memory)에 있어서 기존의 방법들은 저장 용량이 작거나 정확한 연상을 보장하지 못한다. 이는 BAM을 실제 적용시키는 것에 있어서 매우 불리한 요소이다. BPSI/BPHSL[9]에서 제안된 조건들과 본 논문에서 추가된, 학습된 패턴에서 해밍거리가 2 인 패턴에서 학습된 패턴으로 연상될 조건을 두어서, 저장 용량과 잡음 저항 특성을 개선하고자 한다. 연결강도를 생성하는 방법으로는 이완법(Relaxation Method)을 사용했다. Bidirectional Associative Memory(BAM) can store pairs of patterns. However, it doesn't have large capacity nor can guarantee the correct recall. This makes its actual application very difficult. To improve these problems, we can use the conditions which were proposed in BPSL/BPHSL[9] and new condition which is proposed in this paper. With the condition, all the patterns which are in the 2 hamming distance from the stored pattern must be recalled to it, we can approve the capacity of BAM and noise immunity, We use the relaxation method to create the weight of BAM.

Smart Connected Product (SCP) is one domain of ISO, which requires an efficient and effective data quality management process. Data of high quality is vital for SCPs to function properly. We discussed in detail the important issues in data quality, specifically for SCP application domain. For data processing part of ISO 8000-61, this paper proposed a process reference parts. We also identified a fault management process for data processing. The paper includes the different reflections of IoT based data quality characteristics. Lastly, we indicated the ways forward to resolve the issue of too many process capability indicators in ISO 8000-62.
