Parameterization of experimenter behavior characteristics involved in experiments in university laboratories is expected to provide effective information for conducting safe experiments. The authors propose a method to parameterize experimenter behavior characteristics in water measurement operations. In this study, we focus on inquiry-based learning and use a mathematical model to categorize experimenters, quantify characteristics of experimenters, and analyze the characteristics of inquiry-based learning operations. The liquid level behaviors of NaOH(aq) added from burette in each trial produced an indicator, which was fitted to five trials for each experimenter by a logistical curve that is well known as the learning curve, revealing that experimenter characteristics in inquiry-based learning can be parameterized. Simultaneously, the shape of the learning curves showed that experimenters can be categorized into two types, Sshaped learning and gradual learning. In addition, mathematical model analysis was conducted to compare titration after experimenters found the target value with water measurement. After experimenters determined the target value, it was found that titration was a similar operation with water measurement.
In Nagoya University, an investigation on curriculums of safety education for foreign students and researchers, their understanding about the education and safety manuals in a laboratory, and problems, for example, Japanese language, as well as requests for the safety education was carried out using a questionnaire. Based on the result, improvement on the campus safety-management system that is necessary for innovation of global activities of universities is proposed.
In order to reduce the amount of wastes and to promote their reuse and recycle, valuable materials, such as minor and noble metals and their compounds, which were included in disposed reagents generated by academic activities in Nagoya University during the period of 2009 to 2012, have been investigated. Closed up herein were many problems, such as dumping hazardous materials without special care, the absence of a recycling system of valuable chemical wastes and wasting research budgets due to disposing reagents without opening bottles. In addition, establishment of a chemical library of minor elements as well as an exchanging system of information about chemical stocks in each laboratory for the purpose of their sharing.
We first explain the natural disaster environment such as earthquakes and floods and slope failures due to heavy rain in Yamaguchi prefecture in this paper. Then we introduce the preparedness of Yamaguchi University (YU) against these natural disasters, for example, setting up the earthquake observation system, Multi Channel Access (MCA) system as a robust information system and risk management such as Business Continuity Plan (BCP) and so forth. Finally, we introduce the unique research activities regarding to disaster mitigation in YU, i.e., application of satellite remote sensing technology to natural disasters. Analyses to the 2014 Hiroshima slope failure disaster and the 2015 Kinu river flood disaster are explained.
In May, 2013, a leakage incident of radioactive materials occurred at the Hadron Experimental Facility of J-PARC at the KEK Tokai Campus. KEK took this incident seriously, and we conducted not only a thorough investigation to determine the cause and a study of preventive measures, but also reaffirmations and evaluations of the safety management system and the emergency plan implementing procedure of KEK for both the Tsukuba and the Tokai Campuses.In January, 2014, in the middle of the renovation of the facilities and the effort to enhance the safety management system, a fall accident of a worker from a high altitude occurred at the same facility of J-PARC.Responding to this accident, we felt a critical feeling, and urgently conducted an urgent safety patrol with an industrial safety consultant and a special safety training for the personnel of the facility.And we decided to continue safety patrols which are supervised by an industrial safety consultant continuously.Risk assessment was followed by the safety patrols of the facility under a lot of advice from the consultant.The introduction of the safety consultant had much effect to improve our knowledge on safety and our safety awareness. Following the Tokai Campus, an industrial safety consultant was introduced also to the Tsukuba Campus.Safety patrols with the consultant were conducted three times, with much success.Furthermore, we are considering to conduct safety patrols using a risk assessment technique also in the Tsukuba Campus, and to try to build a safety workplace with an objective perspective.
