Analysis of AI Content Detector Tools

이요섭,문필주 한국인터넷방송통신학회 2023 International journal of advanced smart convergenc Vol.12 No.4

With the rapid development of AI technology, ChatGPT and other AI content creation tools are becoming common, and users are becoming curious and adopting them. These tools, unlike search engines, generate results based on user prompts, which puts them at risk of inaccuracy or plagiarism. This allows unethical users to create inappropriate content and poses greater educational and corporate data security concerns. AI content detection is needed and AI-generated text needs to be identified to address misinformation and trust issues. Along with the positive use of AI tools, monitoring and regulation of their ethical use is essential. When detecting content created by AI with an AI content detection tool, it can be used efficiently by using the appropriate tool depending on the usage environment and purpose. In this paper, we collect data on AI content detection tools and compare and analyze the functions and characteristics of AI content detection tools to help meet these needs.

퍼지추론에 의한 PID제어기의 파라미터 Tuning의 구성

이요섭,홍순일 한국융합신호처리학회 2003 융합신호처리학회 논문지 (JISPS) Vol.4 No.4

PID제어기의 파라미터의 조정 방법이 전문가의 경험적 지식과 플랜트 스텝응답 파형 모양에 기초하여 퍼지 싱글톤 추론에 의해 행하는 방법을 나타내었다. 파라미터 조정방법은 두 레벨이 있다. 높은 레벨은 모델링 할 수 없는 플랜트 특성에 대하여 전문가의 Know-how에 기초하여 제어기의 수정계수를 결정하는 것이다. 저 단계는 Ziegler-Nichol 의 한계 감도법의 응답 특성에 의해 특정 계수를 결정한다. 마지막 단계는 량과 제어응답 파형의 면적법에서 얻은 특정량에서 조정 규칙으로 취하고 퍼지추론에 수정 계수와 특정계수로 조정규칙을 만들어 퍼지 싱글톤 추론에 의해 PID제어기의 각 파라미터를 적정한 값으로 자동조정 하는 법을 나타내었다. A PID parameter tuning method was presented by the fuzzy singleton inference, based on step response-shaping of plant and experience knowledge of expert. The parameter-tuning has tow levels. The higher level determines modified coefficients for the controller based on operator's tuning know-how for characteristics of plant which can not be modeled. The lower level determines specified coefficients based on characteristics of response by Ziegler-Nickel's bounded sensitivity method. The last level parameters tuning of a PID controller is adjusted which the modified and specified coefficients makes adjustment rule, and is adjusted the proper value to each parameters by fuzzy singleton inference. Moreover, proposed the tuning method can reflex exporter knowledge and operator's tuning know-how and fuzzy singleton inference is rapidly operated.

1.25Cr-0.5Mo과 2.25Cr-1Mo 강의 동적 변형시효 거동에 미치는 합금원소 및 미세조직의 영향

이요섭,이호중,이종현 대한금속·재료학회 2021 대한금속·재료학회지 Vol.59 No.11

The effect of alloying elements and microstructure on the dynamic strain aging (DSA) behavior of 1.25Cr-0.5Mo (P11, ASTM 335Gr.P11) and 2.25Cr-1Mo (P22, ASTM 335Gr.P22) steels was investigated. For both steels, different cooling conditions such as air-cooling (AC) and oil-quenching (OQ) were applied. Tensile tests were conducted in the temperature range of 20-450 oC and a strain rate in the range of 6 × 10-5- 6 × 10-3 s-1 for the steels with different cooling conditions. The P11AC steel showed serration behavior over a wider temperature range and exhibited higher ultimate tensile strength (UTS) than for the P22AC steel. This is attributed to the effects of alloying elements (Cr, Mo and Si) due to dissolved C, and the ferrite fraction on mechanical behavior. Meanwhile, the P11AC and P11OQ steels also showed different behaviors for DSA starting temperature, DSA temperature range, and serration type. The AC condition showed higher UTS from the interaction solid solution hardening (ISSH) effect due to substitutional Cr, Mo, and interstitial C elements. The calculated activation energy value (Q) for the P11 steel was around 94-103 kJ/mol-1, similar to that of ferritic steels, and it was higher for the P22 steel, with a Q value of 233 kJ/mol-1 from the ISSH effect.

Effect of repetitive wrist extension with electromyography-triggered stimulation after stroke: a preliminary randomized controlled study

이요섭,차유리,김영,황수진,정이정 물리치료재활과학회 2017 Physical therapy rehabilitation science Vol.6 No.3

Objective: The purpose of this study was to explore the effect of repetitive wrist extension task training with electromyography (EMG)-triggered neuromuscular electrical stimulation (NMES) for wrist extensor muscle recovery in patients with stroke. Design: Randomized controlled trial. Methods: Fifteen subjects who had suffered a stroke were randomly assigned to an EMG-triggered NMES group (n=8) or control group (n=7); subjects in both groups received conventional therapy as usual. Subjects in the experimental group received application of EMG-triggered NMES to the wrist extensor muscles for 20 minutes, twice per day, five days per week, for a period of four weeks, and were given a task to make a touch alarm go off by activity involving extension of their wrist. In the control group, subjects performed wrist self-exercises for the same duration and frequency as those in the experimental group. Outcome measures included muscle reaction time and spectrum analysis. Assessments were performed during the pre- and post-treatment periods. Results: In the EMG-triggered NMES group, faster muscle reaction time was observed, and median frequency also showed improvement, from 68.2 to 75.3 Hz, after training (p<0.05). Muscle reaction time was significantly faster, and median frequency was significantly higher in the experimental group than in the experimental group after training. Conclusions: EMG-triggered NMES is beneficial for patients with hemiparetic stroke in recovery of upper extremity function.

이요섭,권재우,이상길,최명렬 한국통신학회 2001 韓國通信學會論文誌 Vol.26 No.12

본 논문에서는 ATM 망의 트래픽 제어 기능 중의 하나인 감시 알고리즘을 제안하고 칩(chip)을 설계하였으며, VHDL을 사용하여 구현하였다. 제안한 알고리즘은 우선순위가 높은 셀의 손실을 최소로 하고, 트래픽의 다중화 및 역다중화 과정에서 발생되는 트래픽의 군집성을 해소할 수 있다는 장점을 갖고 있다. 구현한 칩은 입력 모듈과 UPC 모듈, 출력 모듈의 3부분으로 이루어지며, 편의상, UPC 모듈에서는 메모리 제어시 메모리 어드레스 즉, 커넥션 테이블의 index를 VCI(Virtual Channel Identifier)와 동일하게 할당하였다. 또한 UPC 모듈의 VSA(Virtual Scheduling Algorithm)블럭에서 셀의 도착시간을 계수하는 카운터가 랩-어라운드(wrap-around)할 때 생기는 VSA의 오류를 보정해 줄 수 있는 방법을 제안하였다. In this thesis, a policing algorithm is proposed, which is one of the traffic management function in ATM networks. The proposed algorithm minimizes CLR(Cell Loss patio) of high priority cells and solves burstiness problem of the traffic caused by multiplexing and demultiplexing process. The proposed algorithm has been implemented with VHDL and is divided into three parts, which are an input module, an UPC module, and an output module. In implementation of the UPC module\`s memory access, memory address is assigned according to VCI\`s LSB(Lowest Significant Byte) of ATM header for convenience. And the error of VSA operation from counter\`s wrap-around can be recovered by the proposed method. ANAM library 0.25 $\mu\textrm{m}$ and design compiler of Synopsys are used for synthesis of the algorithm and Synopsys VSS tool is used for VHDL simulation of it
