Background: Antihistamine and anti-allergy medications are widely used during pregnancy. Reading label information is one of the easiest ways to get safety information. But there are content gaps among countries. Objective: To compare the risk level and the recommendation level of antihistamine/anti-allergy drug's label information in pregnant women among Korea, the USA, the UK, and Japan. Method: Study drugs of antihistamine/anti-allergy medications were selected according to Korea drug classification codes. Based on the label information of selected product, risk level was classified into 5 categories as follows: 'Definite', 'Probable', 'Possible', and 'Unlikely', 'Unclassified' according to the level of evidence. Recommendation level was classified into 4 categories as follows: 'Contraindicated', 'Cautious', 'Compatible', and 'Unclassified'. Frequency and proportion were presented according to the each category. To estimate agreement of each category among 4 countries, percent agreement and kappa (k) coefficient were calculated. Results: Total 13 drug ingredients were selected for antihistamine/anti-allergy medications. In risk level, Korea (46%) and Japan (69%) were mostly classified in the category of 'Unclassified', but 'Unlikely' category was more frequent in the UK (62%) and the USA (46%). In recommendation level, the proportion of 'Contraindicated' was highest in Korea (46%) compared to other countries. In contrast, the category of 'Cautious' was 77%-85% in the USA, the UK, and Japan. The percent agreement for risk level was highest in the USA-UK (54%). The recommendation level of Korea-USA showed lowest agreement for percent agreement (46%) and kappa coefficient (k=0.02). Conclusion: We confirmed the differences among safety information provided by four different countries. 'Contraindicated' was more likely in Korea compared with other countries.

According to Railway Safety Act, Korea Transportation Safety Authority (KOTSA) has been entrusted with 'Integrated Railway Safety Audit (IRSA) and has implemented the safety audit to the Railway operation agencies such as Korea Railway (KORAIL) and the Railway facility management organization such as the Korea Rail Network Authority (KR Network). The target of IRSA is to establish the effective rail safety management system and to raise the safety level of the Railway operation and facility agencies by checking synthetically their performance of safety duties with sincerity according to the Railway Safety Act. Even though newly introduced IRSA is conducted smoothly, it is necessary to study the methodology and criteria of the state's safety audit system. The purpose of this paper is to improve the efficiency of IRSA by the comparative research between IRSA and other similar safety audit system and to establish the consecutive improvement concept of IRSA. Second purpose is to confirm the effectiveness of IRSA by the analysis of the relationship between audit results and the safety level of the rail operation agencies.

OSHMS(Occupational Safety and Health Management System) is able to define as a typical convergence of all kinds of activities and elements that support maintaining safety at workplace and protecting employee's health. In particular, fundamental function of OSHMS is preventing diverse hazards at workplace through high level of regulation compliance. Furthermore, insuring safety in workplace, protecting employee's health and increasing effectiveness in manufacture are OSHMS's additional functions. Based on the division of manufacture in 2009 Survey on Current Status of Occupational Health & Safety data, the study analyses certain relation between OSHMS and level of regulation compliance. The main finding is that most activities and elements which formed by OSHMS are being affected by regulation clauses.

Compared with general rivers, fluctuations of the water level and the river bed are severe in the tidal river. In hydro-dynamic aspect, such fluctuation gives different river-bed data to us according to observing period. The time-dependent river-bed data and pre-estimation of the Manning's roughness coefficient which is the key factor of numerical modelling induces uncertainty of evaluating the design flood level. Thus it is necessary to pay more attention to calculate the flood level at tidal rivers than at general rivers. In this study, downstream of the Imjin River where is affected by tide of the West Sea selected as a study site. From the numerical modelling, it was shown that the unsteady simulation gave considerable mitigation of the water level from the starting point to 15 km upstream compared to the steady simulation. Either making a detention pond or optional dredging was not effective to mitigate the flood level at Gugok - Majung region where is located in the downstream of the Imjin River. Therefore, a more sophisticated approach is required to evaluate the design flood level estimation before constructive measures adopted in general rivers when establishing the flood control plan in a tidal river.

The risk of multi-unit nuclear power plants (NPPs) at a site has received considerable critical attention recently. However, current probabilistic safety assessment (PSA) procedures and computer code do not support multi-unit PSA because the traditional PSA structure is mostly used for the quantification of single-unit NPP risk. In this study, the main purpose is to develop a multi-unit Level 2 PSA method and apply it to full-power operating six-unit OPR1000. Multi-unit Level 2 PSA method consists of three steps: (1) development of single-unit Level 2 PSA; (2) extracting the mapping data from plant damage state to source term category; and (3) combining multi-unit Level 1 PSA results and mapping fractions. By applying developed multi-unit Level 2 PSA method into six-unit OPR1000, site containment failure probabilities in case of loss of ultimate heat sink, loss of off-site power, tsunami, and seismic event were quantified.

Purpose: This study is aimed to provide the fundamental data for building the patient safety culture by identifying the perceptions of patient safety culture of hospital nurses. Methods: this study was a cross-sectional survey. For this study, 816 nurses participated from three general hospital and one university hospital located in Gwangju and Chonnam. The data were collected from April to June, 2012 by self-administrated questionnaires. The 'Hospital Survey on Patient Safety Culture'developed AHRQ(2004) and translated in Korean and edited by Je(2006), was used to measure the patient safety culture which the nurses were perceived. The collected data were analyzed with descriptive statistics, t-test, ANOVA, Scheffe test using SPSS window 18.0. Results: With a possible score of 5 points, the average score for nurses'perceived patient safety culture 3.32. In the sub dimension of patient safety culture, the score hospital-level aspects was the highest level of 3.27(0.50) and reporting system medical errors was the lowest of 3.08(0.40). The difference of perception level on patient safety culture were statistically significant depending on demographic and job-related characteristics such as age, hospital level, work experience in present hospital, work experience in present unit, work experience in present area, positions, work hours of week. Conclusion: The scores of perception of which were shown to be relatively low in this study, needed to be improved through continuous education, evaluation and researches. We suggest developing a new tool on patient safety culture fit our country which will help to manage ongoing patient safety culture.

In order to reduce the accident rate of construction in South Korea, governments and its affiliates have been tried to establish a safety culture, however they reached the limit. In addition, researchers recently have conducted regarding the safety climate and concluded that safety climate effect on the safety performance. Although organizational culture and enterprise types are different based on business size, they generalized the level of safety climate with a group only. Therefore, in order to solve this issue, the objective of this study is to analyze the safety climate level of construction company depending on business size in South Korea. In addition, the improvements are suggested on the level of safety climate after problems are drawn from considering organizational culture, enterprise type and construction industry in South Korea. In the future, this study will be used as a baseline for the effects of the safety climate on the safety performance in construction site based on business size.

The IEC 61508 standard was established to specify the functional safety of E/E/PE safety-related systems. Safety life cycle to provide the framework and direction for the application of IEC 61508 is included in this standard. In this paper, we describe overviews, objects, scopes, requirements and activities of each phase in safety life cycle. In addition, we introduce safety integrity level(SIL) which is used for verifying the safety integrity requirements of E/E/PE system and perform a case study to estimate hardware SIL by FMEDA. The SIL is evaluated by two criteria. One of them is the architectural constraints which restrict the maximum SIL by combination of SFF and HFT. The other is the probability of failure which is classified into PFD and PFH based on frequency of demand and calculated by safe or dangerous failure rates.
