RESUMO
Background@#Research on the status of many chemicals used in the semiconductor industry is needed. The purpose of this study was to describe the overall status of chemical use in the semiconductor industry in Korea and to examine it from a health perspective. @*Methods@#Data on the status of chemical use and safety data sheets at 11 of 12 major semiconductor workplaces in Korea were collected. The number of chemical products and chemical constituents, quantities of chemicals, and trade secret ingredients used, as well as the health hazards were examined. @*Results@#On average, 210 chemical products and 135 chemical constituents were used at the surveyed workplaces. Among all chemical products, 33% (range: 16–56%) contained at least one trade secret ingredient. Most of the trade secret ingredients were used in the photolithography process. Several carcinogens, including sulfuric acid, chromic acid, ethylene oxide, crystalline silica, potassium dichromate, and formaldehyde were also used. Only 29% (39 of 135) of the chemical constituents had occupational exposure limits, and more than 60% had no National Fire Protection Association health, safety, and reactivity ratings. Based on the aforementioned results, this study revealed the following. First, many chemical products and constituents are being used in the semiconductor industry and many products contained trade secret ingredients. Second, many products contained significant amounts of carcinogenic, mutagenic, and reproductive toxicant materials. @*Conclusion@#We conclude that protecting workers in the semiconductor industry against harm from chemical substances will be difficult, due to widespread use of trade secret ingredients and a lack of hazard information. The findings of the status of chemical use and the health and safety risks in semiconductor industry will contribute to epidemiological studies, safe workplace, and worker health protection.

RESUMO
OBJECTIVE@#It is necessary to develop new guidelines to delineate the best ways of providing psychosocial care to ensure mental health following a disaster.@*METHODS@#This study applied the scoping review method as a means of establishing evidence-based guidelines for disaster mental health services. A total of 440 literatures were selected through a scoping review of 20,864 documents. Twenty-three recognized experts were invited to participate in the survey and a two-round online Delphi survey was conducted.@*RESULTS@#The concordance rate in the Delphi Round 1 was 95.1%. Six items were excluded and new items were formulated with experts’ suggestions. A total of 23 statements were slightly modified to clarify their meaning. In the Delphi Round 2, all items were met with consensus. The three items with the highest consensus among the experts were related to the protection of personal information and privacy. The item with the lowest consensus among experts was related to debriefing. Other items were related to establishing mental health support centers and suicide prevention activities.@*CONCLUSION@#140 items were developed through scoping reviews based on evidence-based methodology. These items were used to describe the disaster mental health support identified in Delphi. The guideline will provide a foundation for effective preparation and response in disaster situations.
RESUMO
PURPOSE: The purposes of the study were to examine the knowledge and practice about Middle East Respiratory Syndrome (MERS) isolation precaution, and to explore influencing factors of the isolation practice among hospital nurses. METHODS: A total of 182 nurses were recruited from four general hospitals where MERS patients had been treated. The knowledge and practice of MERS isolation precaution were measured by the scales developed based on the CDC guidelines. The collected data were analyzed by SPSS/WIN 22 with descriptive statistics, T-test, One-way ANOVA, Pearson correlation coefficients, and hierachical multiple regression analysis. RESULTS: The nurses were 30 years old in average, and half of them had less than 5 years of clinical experience. and knowledge on droplet precautions (β=.171, p=.019) were the significant predictors, explaining 19.6% of variance in the MERS isolation guideline practice. Clinical experience (β=.225, p=.002), working at infection unit (β=−.203, p=.011). CONCLUSION: The knowledge on droplet precaution and general knowledge on MERS were the important modifiable factor to improve the MERS isolation guideline practice among hospital nurses, even after adjusting clinical experience and demographic variables. It is necessary to develop an efficient education program on specific guidelines for prevention and management of infection by improving the knowledge on infectious disease such as MERS as well as droplet precaution which are modifiable factors.
