GE 파워컨버젼 사업부, GE Marine(GE Power Conversion, GE Marine) 한국추진공학회 2019 한국추진공학회지 Vol.23 No.4

자동차 및 항공 부문 등에서는 미래에 점점 더 깨끗한 운송 및 원거리 연결을 위한 플랫폼을 도입하거나 평가하기 위해 전동화 즉, 전기추진 또는 하이브리드추진 플랫폼을 적극적으로 고려하고 있다. 그러나 전동화는 조선해양 분야에서는 그리 새로운 것은 아니며 이미 약 100년 전에 처음 선박용으로 전기 및 하이브리드 추진시스템이 소개되었다. GE는 해군 함정의 추진 부문, 특히 전기 및 하이브리드 추진 기술과 관련해서 매우 초기단계 부터 혁신적인 기술을 도입해왔던 선구자로써 각 추진방식에 대한 장/단점, 앞으로의 방향에 대하여 기술하고자 한다.

An NADPH-Oxidase/Polyamine Oxidase Feedback Loop Controls Oxidative Burst Under Salinity

<P>The apoplastic polyamine oxidase (PAO) catalyzes the oxidation of the higher polyamines spermidine and spermine, contributing to hydrogen peroxide (H2O2) accumulation. However, it is yet unclear whether apoplastic PAO is part of a network that coordinates the accumulation of reactive oxygen species (ROS) under salinity or if it acts independently. Here, we unravel that NADPH oxidase and apoplastic PAO cooperate to control the accumulation of H2O2 and superoxides (O-2(center dot-)) in tobacco (Nicotiana tabacum). To examine to what extent apoplastic PAO constitutes part of a ROS-generating network, we examined ROS accumulation in guard cells of plants overexpressing or down-regulating apoplastic PAO (lines S2.2 and A2, respectively) or down-regulating NADPH oxidase (line AS-NtRbohD/F). The H2O2-specific probe benzene sulfonyl-H2O2 showed that, under salinity, H2O2 increased in S2.2 and decreased in A2 compared with the wild type. Surprisingly, the O-2(center dot-)-specific probe benzene sulfonyl-So showed that O-2(center dot-) levels correlated positively with that of apoplastic PAO (i.e. showed high and low levels in S2.2 and A2, respectively). By using AS-NtRbohD/F lines and a pharmacological approach, we could show that H2O2 and O-2(center dot-) accumulation at the onset of salinity stress was dependent on NADPH oxidase, indicating that NADPH oxidase is upstream of apoplastic PAO. Our results suggest that NADPH oxidase and the apoplastic PAO form a feed-forward ROS amplification loop, which impinges on oxidative state and culminates in the execution of programmed cell death. We propose that the PAO/NADPH oxidase loop is a central hub in the plethora of responses controlling salt stress tolerance, with potential functions extending beyond stress tolerance.</P>

Observations and Remarks on Relative Pronoun Variation in English

( Grace Ge ),( Soon Moon ) 경희대학교 언어연구소 2012 언어연구 Vol.29 No.2

Moon, Gace Ge-Soon, 2012, Observations and Remarks on Relative Pronoun Variation in English, Linguistic Research 29(2), 281-297. This Paper examines the pronominal variation exhibited in restrictive relative clauses with non-human referents in modem American English. On the basis of a small-scale quantitative analysis of the Corpus of Contemporary American English, the paper shows that the choice between the pronouns which and that is primarily conditioned by the medium and genre of communication, as well the level of stylistic formality, It is also suggested that an interplay of grammatical roles and discourse functions further affects the variation in question.

Toward a Ditransitive Prototype:The Gradience of English Ditransitives

Moon, Grace Ge-Soon. 2014. Toward a Ditransitive Prototype: The Gradienceof English Ditransitives. English Language and Linguistics 20.3, 115-134. Ditransitive constructions in English display a wide variation in acceptability judgments. Thepresent paper attempts to account for this variation within the framework of prototype theory. Specifically, it proposes a ditransitive prototype based on both the semantic features identified in previous research as relevant to prototypicaltransitivity and the properties that characterize the canonical ditransitive verb give.Arguing that the acceptability of ditransitive constructions is a reflex of theirpoximity to the proposed ditransitive prototype, the paper demonstrates that the"ditransitivity" of a given clause is determined by an interplay between the objectiveproperties of the clause itself and the speaker's subjective construal of the event described in the clause.

Trimethyl Chitosan Nanoparticles Enhances Dissolution of the Poorly Water Soluble Drug Candesartan-Cilexetil

Candesartan-cilexetil, an angiotensin receptor blocker, exhibits low bioavailability after oral administration due to its low water solubility. Chitosan is considered one of the most promising biopolymers for drug delivery as a vehicle and trimethyl chitosan is a water soluble chitosan derivative. Trimethyl chitosan nanoparticles were prepared by the ionic crosslinking of a trimethyl chitosan solution with tripolyphosphate, at ambient temperatures during stirring. SEM and TEM (scanning and transmission electron microscopy) revealed trimethyl chitosan and trimethyl chitosan nanoparticles between 1,000-3,000 nm and 13-350 nm in size, respectively. Candesartan-cilexetil was loaded on trimethyl chitosan nanoparticles, trimethyl chitosan, gum arabic and commercial water soluble chitosan using an ultrasonic effect, and the potential of the polymers to increase the solubility of candesartan-cilexetil was investigated. Trimethyl chitosan nanoparticles are a superior vehicle for increasing the solubility of candesartan-cilexetil compared to trimethyl chitosan, gum arabic or commercial water soluble chitosan.

刑法上의 不能未遂論

陳癸鎬 전주대학교 사회과학연구소 1996 社會科學論叢 Vol.12 No.-

The incapable attempt is a case to be punished into a would-be criminal because of dangerousness even if the occurrence of effect is impossible. The incapable attempt is accordingly distinguished from hallucinatory crime or superstitutious crime ets. The hallucinatory crime is a case to misrecognized his action to be come under a kind of prohibited norm not even being existence, the superstitious crime is a action to realized some kind of crime by depending on the forces of super-nature. The incapable attempt is also distinguished from incapable crime. It is because that the incapable crime is a kind of crime for convenience, sake can not be punishable because of the nonexistence of dangerousness. There are theories of Quasi-incapable crime, deficient attempted crime, attempt by mistake, incapable crime to be punishable etc, about the character of article 27 of the Criminal Code. But I think the theorie of incapable attempt to be valid. It is because that the article 27 of the Criminal Code provides an incapable attempt as an dangerous action. Actor must start in practice with intent to be an incapable attempt. It requires that the occurrence of effect must be impossible and be dangerous because of the mistake of object or the means of practice for other peculiar requisities of incapable attempt. There are an old objective theory, the theory of actual incapable attempt and legal incapable attempt, the theory of concret dangerousness, the theory of abstract dangerousness, the subjective theory, the impressive theory or the theory of subjective dangerousness etc, for the standard to decide the dangerousness of incapable attempt. But I think the theory of subjective dangerousness to be valid. It is because that the theory of subjective dangerousness can regulate the dangerousness of subjective actor and the Judgement of objective dangerousness very well.

矯正形論에 關한 硏究

陳癸鎬 전주대학교 1980 論文集 Vol.9 No.-

In the attempt to make a research of the nature of punishment, I have viewed a great many different theories on the subject and now have found it appropriate to criticized and sum hem up all. The classical theory of punishment, under which the nature of punishment should be retribution and punishment itself is mere evil carried upon convicted person, is bound to be criticized both for being lack of reasonableness and humanitarian argument. As a result of such a reasonable criticism, punishment must be a sort of educational methods for convicted persons, rehabilitative urgement for him to be sound personally and socially. It promptly set up purposefull theory of punishment in trying to take execution for correctional institution, not executing a penalty. But the problem is about whether or not there will be a man of un-rehabilitative possibility whom purposeful theoretician has presupposed. We know the existence of such a criminal unrehabilitatived experimentally by our efforts but we come to find that medical doctor dose not neglect researching about cure of cancer even though it is hard to heal a cancer. Same for a criminal. Who dare to persist on strong theoretical basis that a man of unrehabilitative possibility should be separate from society? The answered must be in settlement by an educational theory of punishment. And I have not any opposition in taking an educational theory of punishment as an essential theory of modern-day punishment. But I dare to urge the rehabilitative punishment replacing an educational theory of punishment. Of course, the intent of an educational theory of punishment isn't different from that of the rehabilitative punishment. But when taking dynamic, temporal process of punishment into consideration and when considering punishment of material meaning into executive stage, I find it proper to take an expression of rehabilitative punishment to emphasize a characteristic of correctional institution rather than that of an educational theory of punishment.

刑罰의 本質에 관한 새로운 理解

陳癸鎬 전주대학교 정책과학연구소 1988 정책과학논총 Vol.4 No.-

So far as concerned with the nature of punishpent, the theory of retribution and that of purpose, education and rehabilitation have maintained that they are right each other. The theories of such punishment are ultimately dependent on the differences in view of value or punishment as well. In fact , the classical theory of punishment, under which the nature of punishment should be retribution itself is mere evil carried upon convicted person, is bound to be criticized both for being lack of reasonableness and humanitarian argument. The most outstanding reason behind it can be deduced from the fact that we aren't canpletely wrong in moral and we are doubtful as to freedon of an individual. Originally, free will under punishment of retribution has been a core of thinking method for socjal affairs. Thus law in general, especially criminal law has made it the beginning point that responsibility depends upon free will. Such a way of thought asks only for responsibility, not for distributive decision of free will toward future. However, the latter half of 19 century, the development of natural science has made us to realize even our spiritual phenomenon to be influenced by law of cause and effect through actual proof. Thus , the consideration, when applied to field of criminal law, has forced to enhance political meaning of criminal law, has forced to enhance political meaning of criminal law by actual proof. The fact described above has given strong basis for taking purposeful of punishment. Then, today's prevailing educational punishment belonging to a kind of purpose ful punishment which seeke the nature of punishment from a stage of execution with regarding the nature of punishment the same as the purpose of punishment, insists that a crime is a symptom of criminal's antisocial character, and that punishment as a method of crime prevention is to educate convict's antisocial character essentially. But educational punishment should be necessarily criticized as follows : (1) there is an inconsistency that "education" word for a convict can be grasped in a meaning like convict's better treatment. (2) thus, such concept of education comes to become an abstractive concept extremely on all of correctional operations. (3) education for a convict in the content of education can be misunderstood as that of the education of common school. I dare to assert that, from above facts, the nature of punishment should be grasped as rehabilitative punishment for convicts. When 1 clarify the nature of punishment according to the theory of rehabilitation, punishment is not mere a pain to a criminal, but making himself recognize an evil and abstaining in moral motive from committing again.
