Process safety management(PSM) system was implemented in Korea since 1996. It helps reduce and prevent the occurrence of chemical accidents. There has been no review on the feasibility of the threshold quantities of the existing 21 species and the newly added toxic substances such as hydrogen bromide in the PSM system. The threshold quantities of the target toxic substances(25 species) of PSM were compared with domestic and foreign PSM systems similar to those of Korea. Also, we proposed the toxic harmfulness and hazard equation consisted of inhalation toxicity, NFPA index and others. According to this equation, high risk, medium risk and low risk are classified and reflected in the adjustment of threshold quantities. From the above research, It is expected to help to reduce confusion and burden of the workplaces due to the difference from other PSM system and improve in the threshold quantities.

The temporal trends of the prioritized toxic water pollutants generated and discharged from the industrial facilities in the Geum-River basin, Korea were analyzed with the results of the nationwide Water Pollution Source Survey conducted in 2001 - 2012. The statistical results indicated rapid increase in the volume of raw toxic wastewaters whereas the amount of each toxic pollutant kept fluctuating for 12 years. Serious discrepancies in the survey data of the same type of industries demonstrated a low reliability of the survey result, which stemmed from several error factors. A unit-load for each type of industrial facility was devised to estimate the amount of prioritized toxic water pollutant based on the total volume of industrial wastewater generated from the same type of industrial facilities. The supplementary measures with an effective permit issuance policy and adding survey parameters of terminal wastewater treatment plants to use them as references to the Water Pollution Source Survey were suggested as means to minimize the errors associated with the false reports from the industries.

Purpose: A number of reports about the intoxicated patients have been introduced, but there were few multicenter studies. The purpose of this study was to analyse the patients with toxic exposure in the Daejon province. Methods: The patients who were presented to the four academic emergency departments in Daejon with toxic exposure were enrolled from January to June 2003. The collected variables were according to the form which modified from the Toxic Exposure Surveillance System (TESS) of the American Association of Poison Control Centers. Results: The toxic exposure patients were 362 cases which is $0.78\%$ of total patients presented to the emergency department. The most common exposure site was home ($84\%$). Eighteen percent of cases were exposed by two or more substances. The most common substance was the pesticides ($34.8\%$), and the non-prescription drugs ($32.6\%$) was followed. The suicidal attempt was the top reason for exposure ($67.1\%$). The route of exposure other than ingestion was $3.6\%$. Although the most patients left the hospital within a day, the average treatment period was 4.4 days. Thirty-one patients ($8.6\%$) were expired, and 22 among them were exposed to the paraquat. Conclusion: We reported the current status of toxic exposure in Daejon province by modified TESS style.

Purpose: The aim of this study was to investigate toxic exposures in emergency centers with using a toxic exposure surveillance system-based report form as a preliminary study. Methods: We retrospectively reviewed the medical records of toxic exposure patients who visited emergency centers from January to December 2008. Results: 3,157 patients from 11 emergency centers were enrolled. Males were involved in 47.9% of the total cases of exposure and in 60.1% of the cases of fatal exposure. Suicidal intent was the most common (61.0%) reason and most (87.4%) fatal exposures were suicidal. Pesticides were involved in 30.7% of the cases and sedative/hypnotics/antipsychotics were involved in 20.5%. The substances most frequently involved in fatalities were pesticides, and a 48.4% fatality rate was recorded for paraquat exposure. Conclusion: The toxic exposure data showed the preliminary poisoning events in emergency centers. It is recommended that toxicology professionals should develop a toxic surveillance system and serial reporting should be performed.

The technology of interiors is currently developing around the world. According to various studies, the use of plants to create an environment in the home interior is increasing. However, households using furniture are designed as environment-friendly environment interiors, and in Korea and abroad, plants are used for home interiors. Unexpected accidents are occurring. As a result, there were books and broadcasts about the dangers of specific plants, but until now, accidents continue to occur because they do not properly recognize the dangers of specific plants. Therefore, in this paper, we propose a toxic plant identification system based on a multiplicative neural network model that identifies common toxic plants commonly found in Korea. We propose a high efficiency model. Through this, toxic plants can be identified with higher accuracy and safety accidents caused by toxic plants.

This study analysis the effects of the relationship between LMX and affiliation-OCB, challenge-OCB which is voluntary behavior of organizational members. For this study, the effect of LMX on AOCB and COCB, as well as the mediating effect of AOCB behavior, the moderating role of toxic leadership, were analyzed. The results of studies are as follows. First, LMX had a positive effect on AOCB and COCB, respectively. Second, AOCB has a mediating-effect between LMX and COCB. and Third, toxic leadership confirmed the moderating-effect between LMX and AOCB, and finally the moderated-mediating-effect through AOCB in the relationship between LMX and COCB. Therefore, it was analyzed that the quality of the relationship between leader and member in the organization is an important factor in expanding the positive and voluntary behavior of members in the organization. In addition, since toxic leadership weakens positive and voluntary civic behavior for organizational members, it suggests the need for strategy to overcome toxic leadership for an efficient organization management.

A military is not an organization that seeks profits, such as a company, or a research institute whose results and outcomes can produce. Therefore, it can be said that the nature of the bureaucracy is stronger than any other organizations, which perform the task centered based on ranks. In addition, as military missions deal with national and operation security which is closed with each other and more conservative compare to other organization. In this circumstance, the role of military organization and leaders is to carry out their duties with the cost of people's lives, and indeed, leades and leadership in military are more important than those of any organizations. However, many researches are lacking or focused on leadership research in a limited field, especially positive field, developmental, constructive leadership research and researches that are not focused on that area are limited. Already in the United States, research on negative leadership has been actively conducted under the direction of the Secretary of US Army Thomas E. White in 2003, how toxic leadership is serving in military organizations and on the battlefield. Now they realize how toxic leadership had impact on missions in military organizations and on the battlefield. The purpose of this study is to collect and analyze qualitative and quantitative data on the negative leadership of military organizations that have not been studied. The aim of this study was to establish a literature study on the scope and behavior of toxic leadership among negative leadership and to build empirical data on toxic leaders of current military organizations, and to create occupations that occur when subordinates work with toxic leaders. This study analyzes changes in satisfaction and organizational cohesion that mediates results and causes. This study will be more urgent and important for groups that prioritize groups and organizations over individuals, and it may provide new directions for the role and impact of military leaders from attempting these studies.

Purpose: The Tox-Info system is a poisonous substance information database developed by the Korean National Institute of Food and Drug Safety Evaluation. The aim of this study was to estimate the coverage effectiveness of the Tox-Info system by comparing the toxic substances included in the database with the distribution of the toxic substances implicated in the cases of intoxicated patients presenting to emergency departments. The secondary aim of the study was to propose any additional substances that should be added to the database. Methods: We retrospectively reviewed the medical records of patients suffering with toxic exposure who had visited any of 12 selected emergency departments in Korea from January 2010 to December 2011. The identified toxic substances were classified into groups including prescription drugs, agricultural chemicals, household products, animals or plants, herbal drugs, and others. We calculated the coverage rate of the Tox-Info database relative to the number of intoxication cases and the type of toxic substances involved. Results: A total of 5,840 intoxicated patient records were collected. Their mean age was $46.6{\pm}20.5$ years and 56.2% were female. Of the total intoxication cases, 87.8% of the identified toxic substances were included in the Tox-Info database, while only 41.6% of all of the types of identified toxic substances were included. Broken down by category, 122 prescription drugs, 15 agricultural chemicals, 12 household products, 14 animals or plants and 2 herbal drugs involved in poisoning cases were not included in the Tox-info database. Conclusion: This study demonstrated the clinical usefulness of the Tox-Info system. While 87.8% of the substances involved in the cases were included in the Tox-Info database, the database should be continuously updated in order to include even the most uncommon toxic substances.
