The MIM(metal-insulator-metal) capacitors with the Al/PMMA/ITO/Glass structures were manufactured according to various PMMA concentration of 1, 2, 4, 6, 8 wt%. The lowest leakage current and the largest capacitance were found to be 2.3 pA and 1.2 nF, respectively, for the device with 2 wt% PMMA concentration. The measured capacitance of the devices was almost same values with the calculated one. The optimum film thickness was obtained at the value of 48 nm, showing that the capacitance and leakage current were 1.92 nF, 0.3 pA at 2 wt%, respectively. From this experiment, the PMMA gate insulator films can be applicable to the organic thin film transistors.

Methanol was examined as supplemental fuel for open chamber type and pre-combustion chamber type diesel engine. Pre-determined quantities of diesel oil were injected as ordinary diesel engines and methanol was added at inlet pipe using venturi, nozzel and and float chamber for the rest of the charge. In this mode of operation, addition of methanol reduced inlet and exhaust temperature. Inlet air quantities were essentially unchanged in spite of lower inlet temperature. Exhaust smoke was significantly reduced At light load when both diesel oil and methanol were introduced with small quantities, specific heat consumption was considerably increased. However, with the increase of the quantity of methanol or diesel oil, specific heat consumption was improved. With sufficient quantities of diesel oil enough to produce the power above 3/4 load, addition of methanol showed better thermal economy.

This article relates to criminological implications how physical circumstances and psychological experiences harmfully affect death-row prisoners. They should have been executed right after their final verdict, however, they have endured their life for long period of time without execution. Since they can be put to death legally and practically at any time, they have lived under the extreme stresses and experienced deathlike fears for the long time. With a stigmatized red name-tag outrightly different from others, their everyday life on a death row has been lonely and disconnected causing the fear of death. None has discussed the so-called death-row syndrome and the circumstances and experiences of death-row prisoners in Korea. As an active prison warden, the author interviewed in-depth thirteen convicts on death-row and analysed qualitatively their narratives about their physical circumstances and psychological experiences. Recently they could get along with other prisoners in prison cells and participated in working at prison factories. For all the changed conditions of death-row prisoners, the article discloses that their conditions and experiences relate to the so-called death-row syndrome. It is proved by delayed execution, poor conditions, and deteriorated psychological sufferings. Therefore, death-row syndrome should be considered on the issues of the abolition and execution of death penalty.

국제인권기준에 따른 수용자 금치제도의 개선방안 : 금치위주의 징벌집행 관행 개선을 중심으로

유병철(Yoo, Byung-chul) 한국공안행정학회 2021 한국공안행정학회보 Vol.30 No.2

금치는 교정시설 수용자가 규율을 위반할 때에 부과될 수 있는 여러 징벌 중의 하나인데, 가장 무거운 징벌이기 때문에 구금된 수용자에게는 매우 민감한 영향을 미친다. 그동안 수용자 징벌제도가 꾸준히 개선되었음에도 금치는 여전히 인권침해 논란의 중심에 있다. 만델라규칙 등 국제인권기준은 금치제도의 문제점 해결과 관련하여 시사점이 될 수 있다. 현재 정부는 새로운 인권 수요와 변화·발전하고 있는 국제기준에 부응할 수 있는 행형정책을 펼치고 있으므로 금치제도를 국제적인 인권기준을 참고할 필요가 있다. 만델라규칙은 규율위반행위에 대해 처벌할 때 비인간적이거나 모욕적으로 처우하거나 처벌하지 않아야 하고, 모든 징벌처분에 인권침해가 없어야 함을 요구하고 있다. 특히 특수한 경우에 한하여 최후의 수단으로 허용되어야 한다. 우리나라 현재의 금치제도 운영실태를 보면 여러 문제가 있다. 우선, 수용자가 규율을 위반하는 경우 14가지의 징벌이 적용할 수 있지만, 실제로는 대부분 금치만 부과하고 있다. 실무상 45일을 초과하는 금치도 가능하다. 우리나라는 모든 수용자에 대해 금치를 부과할 수 있어서 금치 부과대상에 제한이 없고, 적용방법도 모든 수용자에게 같다. 개선을 위한 첫 번째 방법은 금치처분 부과를 대상 수용자에 따라 다르게 정하는 것이다. 징벌의 종류를 경비처우급에 따라 차등적으로 부과하거나, 여성수용자와 소년수용자, 장애수용자 등 특별한 보호가 필요한 수용자에게 원칙적으로 금치를 제한하고, 특히 임산부와 유아양육 수용자는 금치를 금지하는 것이 필요하다. 두 번째 방법은 경미한 규율위반행위에 금치를 부과하는 대신, 처우제한실을 지정·운영하는 것이다. 처우제한실에 수용하여 해당 처우를 제한함으로써 징벌목적을 달성하는 것이다. 세 번째는 우리나라가 ‘약한 의미의 금치’라고 할지라도 금치기간을 현재보다 더 단축하는 것이 바람직하다. 만델라규칙은 15일을 넘지 않아야 한다고 하지만, 이것은 하루 22시간 다른 사람과 접촉이 전혀 없는 정도의 ‘강한 의미의 금치’이므로 우리는 영국의 21일, 독일의 4주를 참고하면 우리 실정에도 적용할 수 있다. Disciplinary segregation is one of the disciplinary sanctions that can be imposed on prison inmates when they violate discipline. Disciplinary segregation is the heaviest of many types of disciplinary sanctions and has a very sensitive effect on inmates. Despite Korea s steady improvement in the prison service, disciplinary segregation is still at the center of controversy over human rights violations. For the prison administrators, disciplinary segregation is a very important means of maintaining law and order in prison and keeping the safety of correctional people. The current government is struggling to cope with new human rights demands, so the disciplinary segregation system needs to be reviewed by referring to international human rights standards. As United Nations Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules) require, in no circumstances, the disciplinary segregation should not amount to torture or other cruel, inhuman or degrading treatment or punishment. The Rules for instance require that the indefinite or prolonged segreation shall be prohibited. The disciplinay segregation should only be permitted as a last resort, especially in special cases. According to the current prison situation in Korea, there are many problems in light of international standards such as the Mandela rules. First of all, 14 disciplinary sanctions can be applied if inmates violate discipline, but in reality, most of them impose only disciplinary segregation. In practice, disciplinary segregation exceeding 45 days is also possible, which the Mandela Rule regards inhumane. In addition there is no restriction on the subject of imposition of disciplinary segregation, and the application method is the same for all prisoners. International human rights standards may be implications for prison issues in Korea. The first method is to determine the imposition of an disciplinary segregation differently depending on the discipline violators. In principle, it is necessary to impose the types of disciplinary segregation differently depending on the prisoner security level, or to restrict abstinence to prisoners in special need of protection, such as female prisoners, juvenile inmates, and disabled inmates, especially pregnant women and infant care inmates. The second method is to designate and operate a Treatment Restriction Room instead of disciplinary segregation on minor violations of discipline. The purpose of this is to be achieved by accommodating the violators and restricting some treatments as a disciplinary sanction. Third, it is desirable to shorten the period of disciplinary segregation even if the segregation in Korea does not regards as severe as the sanction the Mandela Rule prohibits. Mandela Rule argues that it should not exceed 15 days, but the segregation in the Rule is such that there is no contact with anyone else for 22 hours a day. Therefore Korea will have to set the period of disciplinary segregation by referring to the practices of UK (21 days) and Germany (4 weeks).

This paper represents a study on the development of the conceptual design for the bicycle transmission by TRIZ. At first the problems of the transmissions of the commercial bicycles was analyzed. And its development object was defined in connection with the improvement direction. The developed conceptual design was compared with the registered patents and practical new devices at the Korea Industrial Property Office. The Comparison shows the developed conceptual design is on the same level with the above mentioned, and the usefulness of TRIZ methodology.
