  • Background: This study aimed to update suicide-related indicators, including the number of suicidal deaths, suicide rate, and the prevalence of suicidal ideation and suicide attempts. We observed trends in suicide-related indicators based on up-to-date information. Methods: This study used five data sources to evaluate the trends of suicide-related indicators: Statistics Korea (1983-2021), Korean Wealth Panel Study (KOWEPS, 2012-2021), and Korea Health Panel Survey (KHP, 2010-2013, 2016-2019), Korean National Health and Nutrition Examination (KNHANES, 2007-2013, 2015-2021), Korean Community Health Survey (KCHS, 2008-2009, 2013, 2017, 2021). Results: The suicide rate per 100,000 population increased from 25.7 in 2020 to 26.0 in 2021. The rates of suicidal ideation from recently available data were 4.28% (KNHANES, 2021), 6.52% (KCHS, 2021), 1.61% (KOWEPS) and 7.10% (KHP, 2019). The suicidal attempts rates were 0.46% (KNHANES, 2021) and 0.34% (KCHS, 2021). The annual percentage change (APC) of suicide rate showed that suicide rates increased in the younger population (APC=9.02% in <19 years, APC=5.13 in 20-39 years) although the rates decreased in the older population (APC=-3.37 in 60-79 years, APC=-2.25 in >80 years). Conclusion: The suicide rate and related indicators increased in 2021 compared to 2020. Thus, continuous observation and appropriate suicide prevention policies as well as studies about the factors that affected the increase in 2021 are needed.

  • We developed a GPS digital signal processing FPGA IP, SIGP-1001 to replace the obsolete GP2021 device, which has been used for many space-borne GPS receivers. From a series of tests, we verified that SIGP-1001 has equivalent performance to the GP2021 device under the same operating condition and concluded that SIGP-1001 can replace the GP2021 device. The reliability of a GPS receiver can be improved by using a space-grade FPGA with SIGP-1001 instead of the GP2021 device and its performance is expected to be improved by increasing the number of search channels.
