An Optimal On-demand Scrubbing Solution for Read Disturbance Errors in Phase-change Memory

Moonsoo Kim,Juhan Lee,Hyun Kim,Hyuk-Jae Lee 대한전자공학회 2021 IEIE Transactions on Smart Processing & Computing Vol.10 No.1

Phase-change memory is a promising technology due to its attractive properties. However, phase-change memory is difficult to commercialize because of its reliability issues. A read disturbance error, which is the main cause of reliability issues, occurs when a cell is repeatedly read. A conventional solution for read disturbance errors is periodically scrubbing the cells. However, this method requires read counters to count the number of reads per word. This paper proposes an on-demand scrubbing solution that does not require read counters, which significantly reduces resource overhead. The proposed method observes the number of errors in a word using error-correcting code. If the number of errors is larger than a pre-defined threshold, scrubbing is performed to fix the errors. The proposed method removes nearly 1GB of hardware overhead required by read counters, and fixes more than 99.99% of read disturbance errors.

Optical configuration for symmetric and high contrast ratio in three-dimensional polarization switching display.

Kim, Taehyung,Kim, Sunhwan,Park, Kyung-Won,Lee, Seung-Chul,Park, Moonsoo,Choi, Suk-Won Optical Society of America 2012 Optics express Vol.20 No.10

<P>We propose an optical configuration to achieve symmetric and high contrast ratio (CR) in three-dimensional (3D) polarization switching (PS) displays. This optical configuration is accomplished using three retardation films and a 관/2 retardation switching panel. Typically, 관/2 retardation switching in the PS panels has an unanticipated asymmetric CR on the left- and right-hand side of 3D glasses because of the wavelength-dependent phase dispersion. To overcome this problem, we designed an optical configuration and applied it to the electrically controlled birefringence (ECB) cell. As a result, symmetric and high CRs are obtained for the 3D PS display.</P>

워즈워스의 ‘1837년 대륙여행 시편’에 대한 연구

김문수 ( Kim Moonsoo ) 한국방송통신대학교 통합인문학연구소 2019 통합인문학연구 Vol.11 No.2

윌리엄 워즈워스의 후기 시는 시 형식상으로 소네트를 주로 이용하고, 주제적인 면에서 ‘여행’을 많이 다룬다. 그의 여행시편은 『1820년 대륙여행의 기록들』이 실질적인 시작이며, 두 편의 스코틀랜드 여행시편을 거쳐, 『1837년 이탈리아 여행의 기록들』로 종결된다. 이 마지막 여행시편은 처음에는 로마에 대한 기대와 더 큰 실망이 교차되지만, 최종적으로 로마의 미래에 대한 이 시인의 간절한 기원으로 마무리된다. 폐허화된 로마는 자신의 노년을 상기시키면서, 평온한 위엄, 온화한 아름다움과 같은 노년의 가치를 소중하게 인식하게 만든다. 이러한 폐허와 노년에 대한 인식은 자연스럽게 종교적 가치에 대한 인식으로 이어지는데, 종교의 내밀한 신비성, 신앙적 성취의 어려움 등에 대한 논의를 거쳐 성 프란체스코를 통한 올바른 종교의 모습을 제시하는 방향으로 이어진다. ‘시인’ 워즈워스는 이 모든 가치들을 시(예술)에 대한 믿음과 결합시키고, 대시인의 반열에 서려는 내밀한 소망도 비춘다. 폐허화된 로마에 대한 인식에서 시작된 1837년 여행시편은 노년과 종교에 대한 인식, 시인으로서의 소명이 종합되면서 끝난다. 이 작품의 교훈성에 대해서는 종래에 비판도 있었지만, 워즈워스 문학의 본령이 도덕, 윤리, 철학이었다는 사실이 재인식되면서 이 여행시편의 도덕적 메시지 또한 다시금 주목에 값하게 될 것이다. Many of William Wordsworth’s later poems are composed in ‘sonnets’ and thematically deal with ‘tour.’ His tour poem series begins with Memorials of a Tour on the Continent, 1820, and with 2 series on the Scotland tours ends with Memorials of a Tour in Italy, 1837. The last tour poem series at first fluctuates with the expectations of and later disappointments at Rome, but finally ends with the poet’s earnest prayer for the Rome’s future. Ruined Rome reminds Wordsworth of his own old age, and makes him recognize the remaining virtues of old age, such as peaceful majesty and genial beauty. His recognition of ruin and old age naturally leads to that of religion, and he discusses the mysteries of religion, the difficulty of attaining religious solemnity and the true ideal of religion through the examples of St. Francis. The ‘poet’ Wordsworth combines all these worths with the belief in poetry (art), and he even dreams of becoming a historically great poet. 1837 tour poem series begins with the recognition of ruined Rome, and concludes with Wordsworth’s recognitions of old age, religion and poet’s vocation. Some past scholars criticized the moral lessons of these poems. However, in the present days the fact that the main subjects of Wordsworth’s literature are morality, ethics and philosophy is being rediscovered, and the moral values of the 1837 tour poems will also be reappraised.

This experimental study presents the results of the cooling performance test of a CO₂ heat pump system for fuel cell vehicles. The experimental facility provides the cool ing and heating environment for cabin and heat releasing component. The test loop is designed to target the cooling capacity of 5kW and its coefficient of performance (COP) of 2.2. The cooling performance of the heat pump system is strongly dependent on the refrigerant charge and the degree of superheat. We carried out basic experiments to obtain optimum refrigerant charge and the degree of superheat level at the internal heat exchanger outlet. The heat pump system for fuel cell vehicles is different from that of engine-driven vehicles, where the former has an electricity-driven compressor and the latter has the belt-driven (engine-driven) compressor. In the fuel cell vehicle, the compressor speed is an independent operating parameter and it is controlled to meet the cooling/heating loads. Experiments were carried out at cooling mode with respect to the compressor speed and the incoming outdoor air speed. The results obtained in this study can provide the fundamental cool ing performance data using the CO₂ heat pump system for fuel cell vehicles.

대리모가 출산한 자의 친생자관계 ― 가족법에서의 경로의존성 비판 ―

김문수 ( Kim Moonsoo ) 연세대학교 법학연구원 2018 法學硏究 Vol.28 No.4

서울가정법원은 최근에 출산 대리모를 통하여 출생한 자의 친모가 누구인지에 관한 결정을 내렸다. 법원은 난자를 제공하여 아기와 혈연관계가 있는 의뢰모가 아닌 임신과 출산을 한 대리모가 친생모가 된다고 판시하였다. 결정 이유에서 법원은 임신과 출산을 모성의 결정적 인자로 보는 전통적 태도를 고수하면서 몇 가지 새로운 이유를 들어 출산 대리모의 경우에도 그것이 정당함을 설시하였다. 첫째로 출산은 그 확인이 용이하고 명확하다는 점, 둘째로 임신기간 중 대리모와 아기 사이에 형성된 정서적 유대 또한 법적으로 보호되어야 할 모성의 요소라는 점, 셋째로 그러한 출산 모성이 무시된다는 것은 국민적 정서와 가치에 반한다는 점이다. 이 논문은 위의 이유들을 법률해석, 역사적 사실, 그리고 대리모에 관한 실증적 연구에 기초하여 재검토하고 법원의 태도를 현대 가족법에서의 ‘경로의존성’의 예로서 비판한다. 첫째, 민법상 친생자관계는 문언적으로 생물학적 친자관계를 의미하는 것으로 해석된다. 둘째, 임신과 출산은 보조생식기술이 없던 시대에 생물학적 모성을 확인하기 위한 사실적 증거로 취급된 것이지 친생모자관계를 결정하는 규범적 기준이었던 것이 아니다. 따라서 출산 대리모 상황에서는 더 이상 적용될 수 없다. 셋째, 새롭게 인식된 소위 출산 모성이라는 것은 주로 추측된 주관적 감정에 기초한 것으로 대리모와 아기에 관하여 확인된 객관적 사실에 근거한 것이 아니다. 따라서 법적 보호 가치를 인정하기 어렵다. 이처럼 모성 결정에서뿐만 아니라 부성 결정(혼인에 의한 친생추정)에서도 볼 수 있는 기존의 태도를 고수하려는 경향은 세계적으로 나타나는데, 이는 현대 과학기술에 의하여 극적으로 변화된 사정을 고려하지 아니하는 것으로서 경로의존성으로 설명될 수밖에 없을 것이다. 이 논문은 이러한 경로의존성이 폐기되어야 하며 출산 대리모가 낳은 아이의 친모는 의뢰모가 되어야 함을 주장한다. 또한 이렇게 하는 것이 현행법 하에서 새로운 입법 없이도 다양한 대리모 사례와 관련된 법률문제를 당사자의 의사와 자녀의 복리에 부합하게 무리 없이 해결할 수 있도록 한다는 것을 보인다. 마지막으로 서울가정법원에까지 이르게 된 법적 분쟁의 원인이 된 가족관계등록과 관련한 실무적 문제에 대한 해법도 상세히 제시한다. The Seoul Family Court passed judgment of late on the issue of who is the legal mother of a child born through a gestational surrogate. The Court decided that the surrogate mother who carried and gave birth to the child was the natural and legal mother as opposed to the intended mother who provided the egg and had the genetic tie with it. In its opinion, the Court sticked to the traditional way of determining the mother which sees pregnancy and birth as the decisive factor of maternity, and justified it even in the surrogacy case with several new reasons: i) it is an easy and clear way to determine the mother to the newly born; ii) the emotional tie formed during pregnancy between the surrogate and the baby is also an important element of maternity that should be legally recognized; iii) and it does not go along with the national sentiment and value that such gestational maternity is ignored. This Article reviews those rationales based on legal interpretation, historical facts and positive researches about surrogacy and criticizes the Court’s attitude as an example of path dependence in modern family law. First, the ‘natural parentage’ in the Civil Act is interpreted to mean biological parentage in literal sense. Second, pregnancy and birth was treated as a factual evidence of not as a normative element of natural maternity in a world without assisted reproductive technology. It should not be therefore decisive any longer in the gestational surrogacy situations. Third, the newly recognized value of “gestational maternity” is mainly based on supposed subjective feelings not on observed objective facts concerning the surrogate and the baby. So it does not pass muster to get legal recognition. All the tendency in determining not only maternity but also paternity (marital presumption) in which the courts around the world ever try to adhere to the traditional rules regardless of the situations dramatically changed by modern technology exemplifies the path dependence in family law. This Article maintains this path dependence should be forsaken and that the intended mother should be the legal natural mother of the surrogate-born child. And it is shown that this position would also smooth the legal processes related with various surrogacy cases according to involved parties’ intents and the best interest of the child under the existing regulations without any new legislation. Lastly, a solution to one sticking point that had caused the litigation brought before the Seoul Family Court is presented in detail.

워즈워스의 「다양한 소네트」 에 관한 연구

김문수(Moonsoo Kim) 한국영미문학교육학회 2015 영미문학교육 Vol.19 No.2

Later Wordsworth’s principal form of utterance was ‘sonnet.’ His sonnets can be divided between ‘nature’ group and ‘philosophy’ group; the representative of the first is The River Duddon and that of the second is Ecclesiastical Sonnets. However, there is a third group, Miscellaneous Sonnets, which is not a ‘sequence’ in its strict sense but a ‘collection’ of separate poems of various themes. The overall significance of the Miscellaneous Sonnets can be more easily comprehended when we regroup and approach the poems with their separate inner themes—those of ‘nature,’ ‘literature,’ and ‘religion.’ First, Wordsworth’s views on nature are summarized as opposition to city (artificiality), search for integration with nature, praise on nature, and the ultimate sense of latent fear in nature. Second, his views on literature are summed up as the initial belief in imagination and freedom, the next self-restraint with humbleness and modesty, and the final solution through fusing literature and divinity. Third, the poet’s views on life and religion are outlined as the sense of fear and limitation in life, the need of integration and permanence, and the ultimate conviction in future life and divine communion.Miscellaneous Sonnets, with its diverse and profound ‘moral’ utterances whose literary values are recognized anew, can be labelled as an ‘epitome of Wordsworth’s literature.’
