Parricide, the crime of murdering a parent, accounts for about 5% of all homicides. Filicide is the crime of murdering one’s own child. This study aimed to review demographicfeatures and criminal characteristics of individuals who committed parricideand filicide in Republic of Korea (ROK). This study is based on data from the KoreaPolice Crime Analysis System, from 20062013. We assessed the diverse characteristicsof both victims and perpetrators. Over the selected period, 381 parents werekilled by their children and 230 children were killed by parents in the ROK. Parricidescaused by schizophrenic murders accounted for 39.6% of all cases. Moreover,approximately 44.4% of the perpetrators attempted suicide following the maternal filicide. In our findings, psychiatric illness was a very important predictor in parricide, andthese further suggest that young mothers with severe mental illness require carefulmonitoring by mental health support service.

본 논문에서는 반도체 제조장비의 핵심 부품 중에 하나인 질량유량제아가(MFC, Mass Flow Contrailler)를 설계하고 구현하였다. Microchip社의 마이크로콘트롤러(Micracontraller) PIC 16F876을 사용하여 개발된 MFC는 여러가지 문제전을 가진 아날로그(Analog) 방식의 MFC와 고가의 DSP(Digital Signal Processor) 및 고분해능의 AD변환기(Analog to Digital Convertor)를 사용하는 디지털 MFC의 장점을 혼합한 하이브리드형(Hybrid-Type)이다. 본 논문에서 개발된 MFC는 크게 센서부(Sensor Unit), 제어부(Contral Unit), 구동가부(Actuator Unit)로 구성되었으며, 성능향상을 위한 자동보정 (Automatic Calibration) 알고리즘과 표준테이블(eference Table) 방식을 사용하였다. In this paper, an MFC (Mass Flow Controller) which is widely used in many semiconductor manufacturing processes for controlling the mass flow rate of a gas is designed and implemented using the PIC l6F876 of Microchip, Inc, The MFC implemented in this thesis has the form of hybrid-type, i.e., the mixed-type of the analog-type MFC, which has many problems such as low accuracy, and digital-type MFC, which use an expensive DSP (Digital Signal Processor) and an ADC (Analog to Digital Convertor) with high precision. The MFC is consists of the sensor unit, the control unit and the actuator unit, and it has used the automatic calibration algorithm and the reference table method for the improvement of the performance.
