탄산(炭酸)세륨으로부터 나노크기 산화(酸化)세륨 제조연구(製造硏究)

김성돈,김철주,윤호성,Kim, Sung-Don,Kim, Chul-Joo,Yoon, Ho-Sung 한국자원리싸이클링학회 2009 資源 리싸이클링 Vol.18 No.6

나노크기의 산화세륨 분말을 제조하기 위해서는 출발물질로 탄산세륨[$Ce_2(CO_3)3{\cdot}XH_2O$]이 널리 사용되고 있는데, 탄산세륨은 소성을 통하여 탄산기체와 수증기를 방출하면서 더욱 작은 입자들로 쪼개진 다공성 구조의 산화세륨이 형성되며 이러한 다공성의 산화세륨을 분쇄함으로서 나노크기의 산화세륨을 얻을 수 있다. 본 연구에서는 염화세륨용액으로부터 중탄산암모늄을 첨가하여 제조된 탄산세륨의 소성온도, 분쇄시간, 유성밀의 회전속도, 분산제 첨가량 및 장입된 분쇄 볼 크기 등의 변화에 따라 얻어지는 산화세륨의 평균 입자크기 분석을 통하여 탄산세륨으로부터 나노크기의 산화세륨 제조공정 특성에 대하여 알아보았으며, 소성온도 $700^{\circ}C$, 분쇄시간 5시간 조건에서 평균 입자크기 160 nm의 산화세륨 분말을 제조할 수 있었다. Since cerium carbonate becomes porous cerium oxide by releasing carbon dioxide and vapour steam during calcination of cerium carbonate, nano size cerium oxide can be obtained by milling calcined cerium carbonate. Therefore cerium carbonate [$Ce_2(CO_3)3{\cdot}XH_2O$] is used generally for the preparation of nano size cerium oxide. In order to obtain nano size cerium oxide from cerium carbonate prepared by reactive crystallization of cerium chloride solution and ammonium bicarnonate solution, the effects of experimental variables in the milling and calcination of cerium carbonate, such as calcination temperature, milling time, rpm of planetary mill, amount of dispersant and ball size for milling on the size of cerium oxide was investigated in this study. Cerium oxide prepared with the conditions of calcination temperature of $700^{\circ}C$, milling time of 5 hour was 160nm mean particle size.

염화(鹽貨)세륨 수용액(水溶液)으로부터 탄산(炭酸)세륨 결정화(結晶化) 특성(特性) 고찰(考察)

김성돈,김철주,윤호성,Kim, Sung-Don,Kim, Chul-Joo,Yoon, Ho-Sung 한국자원리싸이클링학회 2008 資源 리싸이클링 Vol.17 No.6

본 연구는 염화세륨 수용액으로부터 중탄산암모늄의 첨가에 의한 탄산세륨 합성시, 반응 조건(염화세륨 농도: 0.5-2M, 반응온도: $20-60^{\circ}C$)에 따라 형성되는 탄산세륨 결정에 대하여 고찰하였다. 반응성 결정화 과정에서 반응물의 농도 및 반응온도에 따라 lanthanite 형태의 결정상[$Ce_2(CO_3)_3{\cdot}8H_2O$]과 tengerite 형태의 결정상[$Ce_2(CO_3)_3{\cdot}2.5H_2O$] 등 두 형태의 탄산세륨 결정을 얻을 수 있었다. 염화세륨의 농도와 반응온도가 증가함에 따라 탄산세륨의 결정상은 lanthanite에서 tengerite형태로 변하였으며, 함수의 탄산세륨은 건조 조건에 따라 무수의 수산기가 함유된 탄산세륨의 결정상 구조로 전이되었다. Lanthanite와 tengerite 구조의 탄산세륨은 판상의 결정립들이 서로 간에 응집된 상태로서 크기나 형태가 두 결정상 모두 같은 형상을 가지며, 결정립의 크기는 lanthanite구조가 약 $3{\mu}m$, tengerite구조가 약 $5{\mu}m$이었다. 그러나 수산기가 함유된 탄산세륨[$Ce(OH)(CO_3)$]은 침상의 결정립이 응집되어 있는 상태로서 결정립의 크기는 장축이 약 $7{\mu}m$이었으며, 결정수가 함유되어 있는 탄산세륨과 무수의 수산기 함유 탄산세륨의 형상은 서로 다른 형태를 갖고 있음을 알 수 있다. In this study, the crystallization of cerium carbonate from cerium chloride solution by addition of ammonium bicarbonate was investigated. The concentration of reactants such as cerium chloride(0.5-2M) and ammonium bicarbonate, and reaction temperature($20-60^{\circ}C$) have a great effect on the crystal types of cerium carbonate such as lanthanite-type cerium carbonate[$Ce_2(CO_3)_3{\cdot}8H_2O$] and tengerite-type cerium carbonate[$Ce_2(CO_3)_3{\cdot}2.5H_2O$]. The crystallinity of cerium carbonate changed from lanthanite to tengerite as the concentration of reactants and reaction temperature increased. Transformation of cerium carbonate hydrate was transformed to cerium hydroxy carbonate depended on the drying conditions. Cerium carbonate of lanthanite and tengerite has the shape of aggregates with plate type crystal, and the size of lanthanite and tengerite crystal was $3{\mu}m$ and $5{\mu}m$, respectively. Cerium hydroxy carbonate has the shape of aggregates with needle type crystal, and the crystal size was about $7{\mu}m$.

한국의 피해자학이 범죄피해자정책과 입법에 미친 영향

김성돈(Kim, Seongdon) 한국피해자학회 2013 被害者學硏究 Vol.21 No.2

Dieser Beitrag setzt sich ein Ziel, sich einen Gedanken an dem verstorbene Professor Yongsse Kim zu widmen. Dazu wurde in erster Linie hierbei ein kurze Ueberblick ueber die neu anbebrochene opferorientierte Kriminalpolitik und gesetzgeberische Massnahme dargestellt, die in den letzten 20 Jahren in Korea geleistet worden sind. Danach wurde auch analysiert, ob und inwieweit die Viktimologie als eigenstaendige Wissenschaft auf der einen Seite und Forschungsergebnisse von Professor Yongsse Kim als ein Wissenschaftler auf dem Gebiet der Viktimologie auf der anderen Seite darauf eingewirkt hat. Dadurch koennten wir eine Gelgenheit haben, an dem Verstrobene mit Achtung und Liebe zu erinneren. Aus diesbezueglicher Eroerterungen komme ich folgede Ergebnisse: Unter der zahlreichenden Vorschlaege im Rahmen der opferorientierten Kriminalpolitik and Gesetzgebungen war es erkennbare Verdienst von Prof. Yongsse Kim, eine Systematisierung von non-goverment Opferunterstuezungen aufzubauen und dies standhaft auszudehen. Zudem leistete er zur Institutionalisierung von Konzeption des restorativen Justice einem Programm des Taeter-Opfer-Ausgleiches einen Vorschub, der auch auf weitere gesetzgeberische Vorhaben nicht wenige Einfluss nehmen wuerde. Ueberdies interessierte er auch an die Ausbildung von Praktikern, die der Umsetzung zur opferorientierte Kriminalpolitik zustaendig sind. Er war sicherlich ein leidenschaftlicher Wissenschaftler mit grossem Engagement, der sich auf seine Vorstellung von Viktimologie als eine angewandte Wissenschaft beruht. Er war ein seltner Gelehrter, der ein gesamte Bild von Opferperspektive vor sein Auge gehabt hat. Ich bedauere mich sehr, dass sich sein Lebenslauf sowohl Wissenschaftler auf dem Gebiet der Viktimologie als auch Professor an der Universitaet so unerwartet nicht mehr fortgesetzte. Hiermit pflege ich Andenken den verblueffend von uns gegangene Verstrobene, der aber seine vorbildhafte Forschungsergebnisse fuer uns hitergelassen hat.

조선시대의 죄형법정주의의 이념적 기초와 실천적 함의

김성돈(Kim Seong-don) 성균관대학교 법학연구소 2008 성균관법학 Vol.20 No.2

  The primary objective of this article is to examine which practical implication based on which ideological base is possessed by the principle of legality of Joseon. In addition, this article seeks to appreciate which values of Joseon"s principle of legality can be handed down to today"s criminal law, which is equipped with modern rationalism. The article also looks briefly into the exterior of Joseon"s principle of legality had adopted for the two subjects mentioned above.<BR>  Having explored the principle of legality of Choson I concluded as following: Joseon mobilised constitutional governance to implement Confucionism into their social politics. This process caused the criminal law to display more of the doctrin of mandotory sentencing rather than the principle of legality. The substantial reason to advocate the doctrin of mandotory sentencing was to primarily guarantee an equal penal application by eliminating the judge"s discretion. Judges planned for an objective and equal legal application to reach the ultimate goal of Confucionism in democracy. This was not a simple principle of division of power, but an expression of love of the people by the king, who was the at the peak of the kingdom"s authority. His consideration of an objective and equal legal application had been displayed as the doctrin of mandotory sentencing. In addition, objective law acted as a strict standard for legislative institutions. Merciless punishments sentenced to legislative officials reflects the trict standard, so does their permanent resignation, which limits them from being appointed into office.<BR>  Like so, Joseon"s principle of legality is an important implication which is relevant to today"s penal execution of Korea. In the Korean society, the application of criminal law barely reflects the formal significance of the principle of legality, and is distinctly expressed in the famous Korean quote, "yujeon-mujoe, mujeon-yujoe (money talks and bullshit walks)." Furthermore, significant cases of subjective and unfairlegal application are being strictly applied in crimes committed by the people, whereas relatively light penalties are sentenced for corruption by an authority or crimes committed by government officials. Korea"s distorted criminal policy (perspective), where illegal acts by politicians or government officials are neglected, and law-abiding spirit is emphasised and foced upon the citizen, must seek for basic reconsideration from its past through Joseon"s principle of legality.

조선전기 형사법과 형정운용에 나타난 愛民的 刑事政策

김성돈(Kim Seong Don) 성균관대학교 비교법연구소 2008 성균관법학 Vol.20 No.1

It is possible to detect traces of criminal policy involving tolerance and forgiveness through examining the penalty-related article in the Record of Choson Dynasty. The purpose of this research is to uncover to what extent this criminal policy for the people occupied significance in criminal practice of Choson dynasty. If the operation of criminal system of Choson emphasized on not oppression provoking ruthless fear, but on tolerance, forgiveness and Caring people, then this is moral crux either today’s philosophy of punishment or criminal practice should succeed. Consequently, the research has abstracted examples of commiserative penal administration that showed up from the founding of Choson to codification of Gyonggukdaejon. As a result, it can be said that the early Choson’s commiserative criminal practice came to be the basis of today’s criminal practice as the breakthrough to carry out constitutional and moral state harmoniously. Moreover, as a consequence of such practice having penalty as a measure of displaying generosity and embrace to the people and hence drawing loyalty from them, rather than as a means of oppression and fear, it was possible to perceive that it became essential points in the process of penalty.
