  • In recent days, the accidents have happened at experimental laboratories in universities or institutes. In order to improve safety assurance of workers in laboratories, it is required to carry out systematic study concerned with evaluation of safety and health level. The safety and health inspection checklists were developed and conducted the case study. The case study was carried out laboratory safety inspection with 5 inspectors by the checklists to become aware of safety and health level. From the evaluation results of the inspection, we could be made quantification of laboratory through evaluation of safety and health level in laboratory. It was found that was recognized present states of the laboratory and established a plan for improvements in laboratory safety facilities from the case study. The safety inspection checklists can be used as basic data to establish evaluation criteria of safety and health level.

  • To understand biosafety's current situation in laboratory animal research and risk factors affecting occupational health. Compliance surveys were conducted by questionnaire via Questionnaire Star (an application app on the Internet) in Chinese. Thirty-nine anonymous questionnaires were collected. The surveyed institution has established 24 types of ABSL (Animal Biosafety Laboratory) and biosafety management organizations and systems equipped with safety equipment. Our study also suggests that the principal of the laboratory establishment fails to perform supervision and inspection responsibilities, the inappropriate design of the animal biosafety laboratory, non-standardized personnel training and health management, non-strict waste management, and insufficient emergency management. The administrative department and work units should address certain safety and occupational health risks in laboratory animal research. The author proposes control strategies based on organizational guarantee, personnel management, emergency management, etc., to help prevent risks and ensure occupational health. Due to regional limitations and small sample size, the results may not be generalisable to all parts of the world. However, some of the key common issuesmay also be present in other regions, sowe believe that this research still has some relevance.

  • This study was peformed to explore the current situation of university environmental health and safety (EHS) system and evaluate the effects of such system on university EHS practices. Essential elements for the university EHS system were identified based on the representative examples of foreign universities, and Hey were incorporated into a questionnaire, which was used in this study. Among the academic institutions we surveyed in this study, 89% of the universities employed health and safety manager, and 65% kept departments. However, less than 50% of universities maintained EHS policies, maintained health and established safety committees within the university headquarters, and held health and safety meetings on regular basis. Several basic requirements such as chemical hygiene program and laboratory safety training program lacked in many universities. Some basic surveillance was performed in many universities, however, only few universities carried out surveillance on biological safety, medical examination, and chemical exposure monitoring. EHS system had significant influence on university EHS program (p<0.05). Performances of EHS activities were influenced by presence of EHS policies, and university health and safety committees.

  • This paper shows survey result on safety management status of laboratories in Korea. In Korea, many studies and reports on laboratory safety have been published since the ministry of education, science and technology (MEST) enforced the Act on Establishing a Safe Environment of Laboratories (Lab Safety Act) in 2006. The MEST has surveyed status of safety management in institutions subject to Lab Safety Act in 2008 and 2010. According to the survey result, safety management status of universities and colleges has been improved on several factors such as establishment of safety manual and implementation of safety inspection; while the number of safety managers of universities and colleges have increased. However, the difficulties in performing duties of safety managers has increased because the number of exclusive safety managers has decreased. This paper identifies the similarities and differences between Occupational Safety and Health Act and Lab Safety Act on assignment and duties of safety managers; therefore, this paper suggests a standard to determine the number of safety managers and decide whether or not their duties should be exclusive. Besides current standard that is based on the number of researchers, the number of individual laboratories should be considered. The new method would be helpful to determine the number of exclusive safety managers because the amount of safety managers' duties generally do not depend on only the number of people who may be exposed to any risk but also the number of facilities that may be cause of any accident.

  • Structural Health Monitoring (SHM) researchers have identified Augmented Reality (AR) as a new technology that can assist inspections. Post-seismic structural inspections are conducted to evaluate the safety level of the damaged structures. Quantification of nearby structural changes over short-term and long-term periods can provide building inspectors with information to improve their safety. This paper proposes a Time Machine Measure (TMM) application based on an Augmented Reality (AR) Head-Mounted-Device (HMD) platform. The primary function of TMM is to restore the saved meshes of a past environment and overlay them onto the real environment so that inspectors can intuitively measure dynamic structural deformation and other environmental movements. The proposed TMM application was verified by demo experiments simulating a real inspection environment.

  • Objectives: This study was conducted to analyze the trends of government R&D (R&D) projects related to laboratory safety over the past 20 years. Methods: We collected publications from various databases(DBs) with words such as laboratory(ies), lab(s), researcher(s), laboratory worker(s), safety, environment, hazard(s), risk(s), and so on. Selected publications were analyzed by the research funds and the number of projects according to the investment subject and research characteristics. Results: About 93% of the total R&D budget went to government policy projects, not scientific research. Second, from the perspective of 'safety management activities', most of the research is related to management and inspection at the organizational level. Issues that need to be discussed at the national level like policy governance are not included. Third, focusing on the 'safety management cycle', there were few studies related to 'prediction' or 'post-response'. Fourth, when an analysis framework combining the perspectives of 'safety management activities' and 'safety management cycle' is applied, most of the budget is spent on infrastructure such as digital management systems, whereas basic knowledge for prevention and production of evidence was very few. Conclusions: In order to prevent policy planning without policy evaluation, implementation without strategy, and evaluation without evidence, it is necessary to expand investment in empirical research on risks, research on the effectiveness of current application methods, and research on theory development. The government budget for laboratory safety-related projects should be managed separately from the R&D budget for scientific research. Although less than 5% of the budget allocated to scientific research is the total budget, an optical illusion occurs because both the project budget and the scientific research budget are counted as R&D budgets.

  • This study was conducted to investigate the characteristics of conversion and residue for two EBDCs fungicides (mancozeb and metiram) and their metabolite, ethylenethiourea (ETU) under laboratory conditions. The sampling on the pesticides was done at 0, 1, 2, 5, 7, 9, 12, 15, 19, 22 and 26 days. The amounts of their residues and ETU were analyzed with an HPLC-DAD. The average recoveries were $86.9{\pm}4.3\;and\;90.2{\pm}8.0%$ for mancozeb, $85.2{\pm}2.4\;and\;98.6{\pm}1.6%$ for metiram, and $64.1{\pm}3.4\;and\;80.0{\pm}4.6%$ for ETU. The half-lives of mancozeb and metiram were 7.5 and 27.8 day, respectively. The conversion rates of mancozeb and metiram to ETU ranged from 4.7 to 67.2% and from 7.5 to 34.6%, respectively. These results may be different under the real environmental conditions. Therefore, following many studies are recommended to make the criteria for applying the use and safety for mancozeb and metiram.

  • Monitoring surface cracks is important to ensure the health of concrete structures. However, traditional visual inspection to monitor the concrete cracks has disadvantages such as subjective inspection nature, associated time and cost, and possible danger to inspectors. To alter the visual inspection, a complete procedure for automated crack assessment based on adaptive digital image processing has been proposed in this study. Crack objects are extracted from the images using the subtraction with median filter and the local binarization using the Niblack's method. To adaptively. determine the optimal window sizes for the median filter and the Niblack's method without distortion of crack object an optimal filter size index (OFSI) is proposed. From the extracted crack objects using the optimal size of window, the crack objects are decomposed to the crack skeletons and edges, and the crack width is calculated using 4-connected normal line according to the orientation of the local skeleton line. For an image, a crack width nephogram is obtained to have an intuitive view of the crack distribution. The proposed procedure is verified from a test on a concrete reaction wall with various types of cracks. From the crack images with different crack widths and patterns, the widths of cracks in the order of submillimeters are calculated with high accuracy.
