Recently in Korea, public interest about patient safety has increased because patient safety incidents occurred continuously. In addition, as the way of coping with medical personnel and medical institutions after occurrence of patient safety incident became controversial, the necessity of introducing apology law and disclosure law was raised. We analyzed the contents of apology law and disclosure law in U.S.A and critically examined the legislative movements in Korea. First, the Apology law requires that a medical personnel provide apology, consolation, sympathy to the patient for discomfort, pain, damage or death, and that the expression of apology shall be inadmissible as evidence of an admission of liability in civil action or administrative proceeding. The Apology law is divided into 'full apology law' and 'partial apology law' depending on whether mistake, error, fault, liability, and legal liability shall be inadmissible. Meanwhile, Disclosure law enforces or voluntarily enforces the law to communicate with the patient regarding the disclosure of the incident, the cause of incident, the compensation plan, and the measures to prevent the recurrence in the adverse incident that serious harm to the patient. In Korea, the concern about patient safety incidents has been amplified, and as the importance of communication between the medical personnel and patient has been recognized, the revision bill for the "Patient Safety Act", which adopted the U.S.A apology or disclosure law, was submitted to the National Assembly. The purpose of this study was to critically review the contents of the revised legislation based on the analysis of the apology law and disclosure law in U.S.A. and to provide implications for future legislative direction.

Purpose: There have been terrorist attacks all over the world, causing massive damage. In Korea, there are few cases of terrorist damage, but the lack of the on-site response experience lead to constraints on the opportunity to verify capabilities against terrorism. Therefore, in this study, the chemical terrorism on-site countermeasures is considered as a concept of service, it was possible to draw up improvement alternatives for each element by reviewing at once the interactions between the concerned organizations and citizens in the field and the utilization of the equipment and facilities in the invisible area. Results: It had been evaluated the service process of the counterpart manager from the viewpoint of the victim citizen, who is the beneficiary of the final security service. It has found out the waiting point(W.P) between the victim's civilian incident management, and the element of failure(F.P). Conclusion: In this way, comparing chemical terror incident response manuals belonged to each related organization by fusion of service design approach and scenario technique, It is expected that it will be able to find out more specific problems and to find improvement alternatives.

With the advent of big data, traffic prediction has been developed based on historical data analysis methods, but this method deteriorates prediction performance when a traffic incident that has not been observed occurs. This study proposes a method that can compensate for the reduction in traffic prediction accuracy in traffic incidents situations by hybrid approach of machine learning and traffic simulation. The blind spots of the data-driven method are revealed when data patterns that have not been observed in the past are recognized. In this study, we tried to solve the problem by reinforcing historical data using traffic simulation. The proposed method performs machine learning-based traffic prediction and periodically compares the prediction result with real time traffic data to determine whether an incident occurs. When an incident is recognized, prediction is performed using the synthetic traffic data generated through simulation. The method proposed in this study was tested on an actual road section, and as a result of the experiment, it was confirmed that the error in predicting traffic state in incident situations was significantly reduced. The proposed traffic prediction method is expected to become a cornerstone for the advancement of traffic prediction.

Purpose: At present, there are a variety of serious patient safety incidents related to problems in health information technology (HIT), specifically involving electronic medical records (EMRs). This emphasizes the need for an enhanced electronic medical record system (EMRS). As such, this study analyzed both the nature of and potential to prevent incidents associated with HIT/EMRS based on data from the Korea Patient Safety Reporting and Learning System (KOPS). Methods: This study analyzed patient safety incidents submitted to KOPS between August 2016 and December 2019. HIT keywords were used to extract HIT/EMRS incidents. Each case was reviewed to confirm whether the contributing factors were related to HIT/EMRS (HIT/EMRS-related incidents) and if the incident could have been prevented (HIT/EMRS-preventable incidents). The selected reports were summarized for general clarity (e.g., incident type, and degree of harm). Results: Of the 25,515 obtained reports, 2,664 incidents (10.4%) were HIT-related, while 2,525 (9.9%) were EMRS-related. HIT/EMRS-related incidents were the third largest type of incident followed by 'fall' and 'medication incidents.' More than 80% of HIT/EMRS-related incidents were medication-related, accounting for approximately one-third of the total number of medication incidents. Approximately 10% of HIT/EMRS-related incidents resulted in patient harm, with more than 94% of these deemed as preventable; further, sentinel events were wholly preventable. Conclusion: This study provides basic data for improving EMR use/safety standards based on real-world patient safety incidents. Such improvements entail the establishment of long-term plans, research, and incident analysis, thus ensuring a safe healthcare environment for patients and healthcare providers.

An angular selectivity through the focused readout beam is geometrically analyzed and experimental results are presented. Based on the analysis of geometrical results, we derive a new relation that the angular selectivity depends on incident conditions of the readout beam and independent on the writing conditions. In order to demonstrate our theory, we investigate angular selectivity as functions of following factors: writing beam incident angle, readout beam width and lens focal length. From the experimental results, it is shown that the angular selectivities are 2.632$^{\circ}$, 2.618$^{\circ}$, 2.604$^{\circ}$ when the external half-crossing angles of writing beam are 8$^{\circ}$, 10$^{\circ}$, 14$^{\circ}$, respectively. Applying the same incident angle of the recording beam, angular selectivity is changed by the control of readout beam width and then their properties are 2.632$^{\circ}$, 0.588$^{\circ}$. From these results, we have known that the angular selectivity is very critical to incident conditions of readout beam.

As a study on ballistic protection performance of a weapon system that is used in combat simulation, this paper aims to propose an improvement effect of the ballistic protection performance varying with incident angle of a bullet. For this, live-fire ballistic tests were performed to determine either complete penetration(CP) and partial penetration(PP) of three types of general armor plates made of uniformly rolled steel plates against a small caliber threat using 5.45 mm bullets with various speed. The major test parameter was the material of the weapon system and incident angle of the bullet with the target. Further, to quantitatively analyze the ballistic protection performance, three existing measurement methods were used for ballistic limit velocity. The test results showed that the ballistic protection performance with the incident angle of 30 degrees was 4% to 14% varying with the material of the armor plates greater than that of 0 degrees, which was approximately 1.1 times the performance improvement on average when compared to the conventional angle of incidence of the 0 degree. Those test results are expected to contribute to developing a more realistic combat simulation addressing the parameter improving the ballistic protection performance of an armor plate.

In the past few years, data leakage of information assets has become prominent issue. According to the NIS in South Korea, they found 375 cases of data leakage from 2003 to 2013, especially 49 of cases have been uncovered in 2013 alone. These criminals are increasing as time passes. Thus, it constitutes a reason for establishment, operation and certification of ISMS, even for private enterprises. The purpose of this study is to examine the factors influencing the certification intention of ISMS using EFA (Exploratory Factor Analysis) and regression analysis. We identified expectation factors for certification of ISMS from 13 elements using EFA (Strengthening practical ability & economic effect factor and Improvement of security level & handling incident factor). Next, we examined that the certification intention of ISMS using regression analysis. As a result of regression analysis, Strengthening practical ability & economic effect factor is not significant for the certification intention of ISMS (p<.05). Also, Improvement of security level & handling incident factor have a significant and positive effect on the certification intention of ISMS (p<.05).

In this study, for the purpose of collecting and analyzing target-specific RCS data of target signals simulator for verification/improvement of radar system performance, VHF band monostatic/bistatic RCS of civil aircraft(B-747, B-737) and fighter(F-16) models were analyzed by EM simulation tool. In order to reduce the RCS analysis time, the analysis time and RCS data were compared and cross-verified. Also, the analysis range was selected by examining the interpolation error according to the analysis angle resolution. The RCS data obtained for each model were analyzed separately by the incident/reflection elevation angle and frequency. The RCS characteristics according to the shape of the aircraft and the incident/reflection azimuth angle were described. Finally, the statistical RCS distribution value of each model is presented through RCS distribution histogram analysis. In the future, the RCS database obtained by this study will be used for the target signals simulator of the VHF band radar system.

Safety and quality assessment systems are very important in manufacture, storage, transportation, and handling of hazardous materials(hazmat) to prevent hazmat disasters. At present, hazardous materials exist everywhere in our daily lives with various forms of plastics, household products of cleaning and washing detergents, fertilizers or petroleum-related products. However, hazardous materials are dangerous substances when they are released to human or environment. Hazardous materials become very widely used substances in the age of oil-based industrial economy. The Korean Ministry of Environment (KMOE) describes about one hundred thousand types of chemicals are produced and used worldwide. Over four hundred new chemicals are introduced in every year. A crucial question for the Korean hazardous material management may have been raised: Will you be safe from hazardous material incidents? The gas leak disaster at Union Carbide's Bhopal, India in 1984 that made over 6,400 people killed and 30,000 to 40,000 people seriously injured is the representative case for the safety of hazmat. Korea becomes vulnerable to hazmat disaster due to the development of high-tech industry. Thus, the risk assessment system is required to Korea for transferring abandoned hazmat management systems to self-correcting safety systems. This research analyzed characteristics of various hazmat incidents applying statistical analysis methods including frequency analysis or analysis of category data to hazmat incidents for ten years. All of three analyses of category data indicate the significance of causality between hazmat incident site groups and seasons, regional groups, and incident casualty groups.
