abstract: Background The photolithography process in the semiconductor industry uses various chemicals with little information on their constitution. This study aimed to identify the chemical constituents of photoresist (PR) products and their by products and to compare these constituents with material safety data sheets (MSDSs) and analytical results. Methods A total of 51 PRs with 48 MSDSs were collected. Analysis consisted of two parts: First, the constituents of the chemical products were identified and analyzed using MSDS data; second, for verification of the by products of PR, volatile organic compounds were analyzed. The chemical constituents were categorized according to hazards. Results Forty five of 48 products contained trade secrets in amounts ranging from 1 to 65% A total of 238 ingredients with multiple counting (35 ingredients without multiple counting) were identified in the MSDS data, and 48.7% of ingredients were labeled as trade secrets under the Korea Occupational Safety and Health Act. The concordance rate between the MSDS data and the analytical result was 41.7% The by product analysis identified 129 chemicals classified according to Chemical Abstracts Service No. with 17 chemicals that are carcinogenic, mutagenic, and reprotoxic substances. Formaldehyde was found to be released from 12 of 21 products that use novolak resin. Conclusion We confirmed that several PRs contain carcinogens, and some were not specified in the toxicological information in the MSDS. Hazardous chemicals, including benzene and formaldehyde, are released from PRs products as by products. Therefore, it is necessary to establish a systematic management system for chemical compounds and the working environment.

abstract: The purpose of this study was to investigate the furnishing rate and dental technicians' comprehension level on Material Safety Data Sheet (MSDS) in Jeju province. On line and off line questionnaires filled out by 102 dental technicians were acquired and analyzed by frequency analysis, chi squared test, and one way ANOVA by SPSS 20.0. On average, respondents rated 3.21+ 0.87 on a Likert 5 point scale regarding familiarity with hazardous effects of chemicals, 2.54+ 1.09 to awareness of MSDS, and 2.05+ 1.09 to familiarity with the contents of MSDS. Regarding availability of MSDS or similar information at workplace, 18.6% responded MSDS were furnished, 5.9% responded similar information sheets were provided, 29.4% responded MSDS or similar information sheets were not furnished, and 46.1% responded that they were not sure. Total of 24.5% responded positive to availability of MSDS or similar information, which was higher than result from a similar study from 2010 but lower than that of the 2016 study. Gender difference in awareness and comprehension level of MSDS were noted. No statistically significant differences were noted between graduates of Jeju and of other regions regarding awareness and comprehension of MSDS. Position at work rather than length of employment affected level of awareness and comprehension of MSDS. Efforts to rouse dental technicians' interest in chemical safety may enhance workplace health and safety, and there is room for improvement in MSDS provision and education in dental labs of Jeju.

abstract: Kimia merupakan bidang yang tidak terlepas dari kegiatan riset. Para pelaku riset sangatlah wajib dalam memperhatikan aspek kesehatan dan keselamatan. Untuk itu diperlukan pengetahuan dan pengenalan aspek aspek yang terkait pada suatu bahan kimia. Sehingga dengan dibangunnya aplikasi ini diharapkan akan menunjang kinerja dan meminimalkan potensi kecelakaan kerja para pelaku riset diantaranya teknisi laboratorium, analis kimia, mahasiswa kimia maupun dosen kimia. Algoritma Boyer Moore merupakan metode pencarian pattern di dalam teks, Algoritma Boyer Moore dianggap sebagai algoritma pencocokan string yang efisien sehingga dalam pencarian bahan kimia dengan menggunakan aplikasi pengetahuan umum sifat fisik bahan kimia serta Material Safety Data Sheet (MSDS) Laboratorium menjadi lebih mudah dan cepat. Speech to text merupakan proses mengkonversi input suara menjadi output digital atau teks. Dengan fitur mendengarkan suara pengguna, memahaminya dan mengubahnya ke dalam bentuk output yang diinginkan dan juga melakukan tindakan yang dibutuhkan agar dapat mempermudah pengguna dalam melakukan pencarian. Chemistry is a field that cannot be separated from research activities. Researchers are obliged to pay attention to health and safety aspects. For this reason, knowledge and an introduction to the related aspects of a chemical are needed. So that the construction of this application is expected to support performance and minimize the potential for workplace accidents, including laboratory technicians, chemical analysts, chemical students and chemistry lecturers. Boyer Moore algorithm is a method of searching patterns in the text, Boyer Moore Algorithm is considered as an efficient string matching algorithm so that in the search for chemicals by using applications of general knowledge of the physical properties of chemicals and Material Safety Data Sheet (MSDS) the Laboratory becomes easier and fast. Speech to text is the process of converting voice input into digital output or text. The feature listens to the user's voice, understands it and converts it into the desired output form and also takes the actions needed to make it easier for users to search.

abstract: Because of the vertical combustion characteristics of combustible substances, accurate substance safety information for their safe use, handling and transportation is essential. The flash point, fire point, explosion limits and autoignition temperature (AIT) are important safety parameters which need special attention in chemical plants and laboratories that handle dangerous materials. In this study, tert butylbenzene which is widely used as an intermediate material in the chemical industry was selected. For the reliability of the flammable properties of tert butylbenzene, this study was investigated the explosion limits of tert butylbenzene in the reference data. The flash points, fire points and AITs by the ignition delay time for tert butylbenzene were experimented. The lower flash points of tert butylbenzene by using the Setaflash and Pensky Martens closed cup testers measured 39 degC and 44 degC, respectively. The flash points of tert butylbenzene by using the Tag and Cleveland open cup testers are measured 51 degC and 54 degC. And the fire points of tert butylbenzene by the Tag and Cleveland open cup testers were 54 degC and 58 degC respectively. The AIT of tert butylbenzene measured by the ASTM 659E tester was measured as 450 degC. The lower explosion limit of 39 degC which measured by the Setaflash flash point tester was calculated to be 0.68 vol%
