Greetings

I'm a 4th-year Ph.D. candidate in Computer Science at the University of Toronto, working under the supervision of Prof. Khai Truong.

My research centers human-AI interaction, with an emphasis on accessibility and creativity support, particularly in enhancing "music accessibility" for d/Deaf and hard-of-hearing individuals. One of my main projects involves song signing to support culturally responsive content creation and encourage collaboration between d/Deaf and non-d/Deaf artists. Another aspect of my work focuses on enhancing people's well-being. I am engaged in projects that support individuals with dementia in their out-of-home experiences and encourage mindful eating behaviours among children.

I completed my B.Sci in Computer Science and Engineering at Ewha Womans University, where I was advised by Prof. Uran Oh (Human-Computer Interaction Lab) and Prof. Hyokyung Bahn (Distributed Computing and Operating System Lab). Additionally, I worked as a research intern at the Samsung AI Centre Toronto under the guidance of Dr. Iqbal Mohomed, and at NAVER AI (HCI group) with Dr. Young-Ho Kim.

5. CPU 스케줄링

 <프로세스 특성>

- I/O bound: 입출력 위주 ; short burst

- CPU bound: CPU에서 계산 위주: long burst


<CPU 스케줄링: 단기 스케줄러>

- Running -> Blocked: 입출력 요청 시스템 콜

- Running -> Ready: 할당시간 만료 인터럽트

- Blocked -> Ready: 입출력 완료 인터럽트

- terminate


<스케줄링 기준>

- Utilization: CPU 이용 시간

- Throughput: 단위 시간당 수행한 프로세스

- Turnaround time: waiting time + Burst time

- Waiting time: 큐에서 대기한 시간

- Response time: 첫번쨰로 CPU를 받기까지의 시간


<스케줄링 알고리즘>


1) FCFS: 선착순, convoy effect

2) SJF: burst time 작은 순, starvation 문제

3) SRTF: 남은 burst time 작은 순, 할당시간, 

4) RR: 응답시간 보장, turn - around는 안좋음.

5) Multi level queue: 여러개의 레디 큐. 앞: RR, 뒤: FCFS
