When navigating at sea, informations like other ship's particular are very important to navigator who should make a safe maneuvering. Most of all is obtained through the optical observation and/or the radiotelephone communication, but it is not easy to perceive them when the visibility is restricted or there is some hardness in communication. In this study, we suggest the algorithm that measures the ship's length and speed on the radar screen and estimates the ship's particular such as gross tonnage, breath and type on the base of above two factors.

본 연구에서는 인간의 의사소통이 갖고 있는 복잡한 과정을 고려하여 재난 시 위험의 소통방식에서 나타나는 오류들을 분석하고, 안전문화를 정착시키기 위한 방법 중 가장 효과적인 방법의 하나로 "위험소통"을 그 대안으로 제시하고자 하였다. 또한 안전문화를 개인의 과제가 아닌 조직 내에서의 협동과제로 인식하고, 조직 내 소통을 통한 신뢰가 안전문화에 미치는 영향력에 집중하였다. 본 연구의 제안을 통해 위험소통에 대한 새로운 원칙들을 제시함으로써 조직 내 안전문화의 새로운 방향을 도모하고자 한다.

According to the actual situation of a university, the emergency evacuation simulation is modeled based on the physical sign, evacuation speed and personnel ratio using the pathfinder software.The experimental construction export utilization rate is compared with the preliminary simulation scenario. The simulation results show that the utilization rate of evacuation stairs and evacuation exits is significantly improved.The optimized solution can provide the most effective evacuation passage, and the research results can provide the basis for the rational planning and management of evacuation passage in university experiment building.

This study was conducted to find out factors affecting patient safety management activities at nursing devisions of two university hospitals. The indicators of patient safety activities used in the study were selected from Hospital Survey on Patient Safety Culture which was developed by The Agency for Healthcare Research and Quality in the United States. Data were collected from 372 nurses working at inpatient wards at two university hospitals located in Seoul and Won-Ju cities through the self-administered questionnaires, and analyzed using frequency analysis, t-test, correlation, and regression analysis. The result of this study were as follows. First, The mean of patient safety management activities was 3.41 which was a little bit higher than the average level. The mean of communication within the ward was the highest, whereas that of patient safety management culture was the lowest. Second, there were significant differences in the perception of nurses on patient safety management activities in terms of the educational background, length of employment, and work hours per week. Third, three variables of communication within the unit, attitude of top management, and attitude of nurses have significant positive effects on patient safety management activities. Fourth, 37.4% of the variation in the patient safety management activities was explained by the study variables. In conclusion, hospital administration and nursing managers should make an effort to learn the knowledge of patient safety program, show their deep interest on the patient safety to the employees and motivate them to communicate effectively each other within the work unit to develop a good patient safety culture and system.

The purpose of this paper is to deduct components that are in the group of highest risk(top 10%). the group is conducted for classification into groups by values according to risk priority through risk priority number(RPN) of FMEA(Failure modes and effects analysis) sheet. Top 10% of failure mode among total potential failure modes(72 failure modes) of ESS included 5 BMS(battery included) failure modes, 1 invert failure mode, and 1 cable connectors failure mode in which BMS was highest. This is because ESS is connected to module, try, and lack in the battery part as an assembly of electronic information communication and is managed. BMS is mainly composed of the battery module and communication module. There is a junction box and numerous connectors that connect these two in which failure occurs most in the connector part and module itself. Finally, this paper proposes RPN by each step from the starting step of ESS design to installation and operation. Blackouts and electrical disasters can be prevented beforehand by managing and removing the deducted risk factors in prior.

Background: Health and safety (H&S) on a construction site can either make or break a contractor, if not properly managed. The usage of Building Information Modeling (BIM) for H&S on construction execution has the potential to augment practitioner understanding of their sites, and by so doing reduce the probability of accidents. This research explores BIM usage within the construction industry in relation to H&S communication. Methods: In addition to an extensive literature review, a questionnaire survey was conducted to gather information on the embedment of H&S planning with the BIM environment for site practitioners. Results: The analysis of responses indicated that BIM will enhance the current approach of H&S planning for construction site personnel. Conclusion: From the survey, toolbox talk will have to be integrated with the BIM environment, because it is the predominantly used procedure for enhancing H&S issues within construction sites. The advantage is that personnel can visually understand H&S issues as work progresses during the toolbox talk onsite.

In this paper, we evaluate safety of grounding system which is designed according to IEC standards. Safety assessment of construction site and grounding system of building is needed before construction for the safety of human in building. Until now, in case of domestic field, design of grounding system is proceeded based on methods which are proposed in IEEE Std. 80. In other words, it is not in the situation that grounding system is designed based on IEC standards. Therefore, we propose a method which designs grounding system and evaluates safety of it according to IEC standards. We measure ground resistance of construction site using measuring equipment of ground resistance. Using this value, soil structure and ground resistivity are obtained through program analysis. CDEGS program of SES company is used for simulation analysis.

The objective of this study is to investigate the effect of pesticide-related accident on prices and sales of eggs and the perception of food safety accidents among consumers. For this, we analyzed the impact of the pesticide incident on consumers' purchases by separating large discount stores and eco-friendly specialty stores with econometrics methods. In addition, the value changes for each egg certification were analyzed after the accident. Perception of food safety accidents was conducted through a survey to investigate the awareness of the pesticide-related accidents, changes in purchases, and the causes of the pesticide accidents. Furthermore, the risk analysis was conducted. This results show the importance of trust and communication in food safety accidents between distributors, consumers and concerned authorities. Also, after the accident, consumers' interest and premium exist in the breeding process such as animal welfare, not only in the final product. Therefore in order to actively respond to food safety accidents such as pesticides-related accident, response and improvement are necessary considering various aspects such as risk assessment, risk management, and risk communication.
