        Failure Modes and Effects Analysis of Electronic and Electrical Components at the Use Circuit of P-Type Receiver

        Yo Shep Shim,Sung Ho Song 위기관리 이론과 실천 2016 Crisisonomy Vol.12 No.6

        본 연구에서는 국내에서 중소형 건축물에 가장 많이 사용되고 있는 5회로 P형수신기를 타깃으로 선정하였고, 5회로 P형수신기의 사용자회로와 메인회로 중에서 사용자회로를 중심으로 전기전자부 품에 대한 위험우선순위지수와 중요도를 도출하였다. 구성부품으로 분석하면 Cable에서 2개 모드, Switch 2개 모드, Capacitor 1 개 모드, IC 1 개 모드로 4 개의 구성부품에서 차지하였다. 고장모드는 Cable 의 poor contact/intermittent(112)와 arcing/sparking(121), Switch의 mechanical failure(301)과 inter-mittent/degraded operation (302), Capacitor의 high contact resistance(401) 및 IC 의 drift(501)이었다. 중요 도에서 가장 높게 나타난 고장모드는 Cable 의 Poor contact/intermittent(112)와 Arcing/sparking(121), Diode 의 Shorted(201)였다. P 형수신기의 경우는 Cable 의 연결하는 커넥터부분의 접속불량이 가장 문 제였으며, 이런 접속부의 접속불량은 아크와 스파크를 동반하고 있어 주위가연물이 존재하면 화재 뿐만 아니라 고장을 일으킬 수 있는 조건으로도 작용하였다. Cable 과 Switch 의 관리 및 내구성이 높은 부품의 변경으로 내구연한을 높일 수 있다.. 본 연구는 인적재난위기의화재와 생활안전위기의 생활용품안전에 활용가능하다. This study is aimed to reduce failure rates and failure modes through the arrangement of the list corresponding to the component of the electrical and electronic in the user circuit of a P-type receiver. This paper analyzes a user circuit of monitoring and alarm systems in buildings. In the user circuit, the heaviest failure modes are shown in cables. The results of a risk priority number (RPN) analysis shows that a total of 6 failure modes is shown in the parts of contact/intermittent (112) and arcing/sparking (121) of the cables. Moreover, a mechanical failure (301) and an intermittent/degraded operation (302) of On/Off switch, high contact resistance (401) of a capacitor, and a drift (501) of IC are the other modes of the failure. Consequently, we find that the part of frequent breakdown is the cable and verify that the defect of cable connectors causes lots of failures of user circuits such as contact/intermittent. We expect that these findings will contribute to increase the quality of firefighting supplies and their life-spans.

      • 수중인체모델의 대지접촉시 전기적 특성에 관한 연구

        심요섭(Yo Shep Shim) 산업기술교육훈련학회 2018 산업기술연구논문지 (JITR) Vol.23 No.3

        In this paper, electrical simulations of electric shock accidents at voltages of 220V have been carried out using an Andred s body model underwater. First, we construct a circuit fitting Andred s body model. Then, we compare voltage measurementsat a hand, breast, and the waist, and current measurementsat the same locations, with safety limits of electric current flowing through a body. We conclude from our results that the magnitude and wave of an electric currentpassing through a body mimics the effect ofa heart control signal. It also hasa direct impact on the ventricle of the heart in detailed motion. The simulations have been performed with the ATP-Draw program. Furthermore, this study finds safety issues for an electric angle limit when taking measurements of a flooded body resistance, and the voltage and current passing through each part.

        상실 가족의 심리이해와 목회상담

        전요섭(yo Shep Joen) 한국기독교학회 2000 한국기독교신학논총 Vol.17 No.-

        This research is to suggest a method of pastoral care and counseling for a grief family in a church. A pastor ought to recognize the psychological transformation and methods of consolation for a grief family to do pastoral care and counseling effectively. Especially, this research is focus on the children and the old in a grief family. These people are not apt to overcome death anxiety or cognition of death. As a matter of fact, death and death anxiety always exist human being closely. Anybody is unable to overcome the death and death anxiety. Death brings separation to all human being. Death and death anxiety remain an enemy and as an object of phobia in human`s unconsciousness. Paul Tillich states that death is the biggest event in life process. Also, he calls death to metaphysical shock. Accordingly, it is necessary to decrease of death anxiety and shock in modern ministry. Death and dying are individual thing completely. However, grief, loss and effectiveness of death are not personal but social. Even though some one is terminal ill in bed, this anticipated death brings shock, loss, grief, and psychological trauma. It is serious that the discouragement of a grief family who has care terminal ill. Normally, the grief family feels empty, resentment, anxiety, mental depression, loss, and phobia. These are the traumatic experience, post-traumatic disorder, and scar of death. According to Marvin G. Gilbert & Raymond T. Brock human is unable to overcome totally. However, one is able to overcome death anxiety through faith. Especially, Robert A. Raab makes a statement that one who has Christian affiliation: reading the Bible, prayer, praising God, baptism, and attending worship service is less death anxiety than who has not religious resource. Therefore, it is very important for a pastor to emphasize the means of grace to decrease death anxiety of a grief family. It is possible for a church member to establish faith on death and dying through cognition of the great beyond, kingdom of heaven, judgement of God, forgiveness, resurrection, and Christian charity. John Terner makes sure that not only a dying patient but also a grief family is able to be possible psychotherapy through the Bible study. So¨ren Kierkegaard state that frequence of prayer is very close to death anxiety of a grief family. That is, someone who prays to God frequently, it must he overcame anxiety, phobia, panic, and sorrow on death and dying. Accordingly, a pastoral counselor ought to emphasize means of grace for a grief family.

      • 침수된 전기설비에서 저항비에 의한 인체의 시뮬레이션에 관한 연구

        심요섭(Yo-Shep Shim) 산업기술교육훈련학회 2011 산업기술연구논문지 (JITR) Vol.16 No.3

        In this paper, simulation called an electric shock at voltage of 220[V] in case of inundation as I used a human body model of Andrew. Configuration of a circuit composed it with a human body model of Andrew. At a hand of a human body, chest, the groins and measurement of electric current sold, and voltage composed it so as to consist in chest and legs. As a result, voltage of 110[V] is streaming to 130[V], inside of a thigh on 213[V], chest to a hand after a feeler the almost 0[V] voltage that streamed close to a transposition before a charge power equipment feeler of hands human body. As a human body can develop in a shock or a heart stop etc., and I confirmed it after a direct feeler of charge power equipment, take safe into consideration, and charge power equipment work can know enough underwater it.

        수중인체모델의 충전전원설비 촉수시 전기적 특성에 관한 연구

        심요섭(Yo-Shep Shim) 산업기술교육훈련학회 2020 산업기술연구논문지 (JITR) Vol.25 No.3

        In this study, the electrical simulation of electric shock accidents at a voltage of 220 V was investigated using Andrew s body model in water. The constructed circuit consisted of Andrew s body model. The voltages measured on a hand, breast, waist, were compared with the electric currents measured on the hand, breast, and waist considering the safety limit of an electric current passing through the body. From the results, it can be understood that the magnitude and wave of electric current passing through the body affect the heart s control of a signal, which directly affects the ventricle of the heart in detail. It comes from the simulation through the ATP -Draw program. This study could be useful in solving safety issues for the electric angle limit by measuring flooding body resistance, as well as the voltage and current passing through each part.
