The Capital punishment is a sentence which imposes the defendant to be put to death for his crime, thus depriving him/her of life and it's the heaviest punishment of all. It is a very sensitive issue in the sense that it denies a person's life and dignity. It is also an on-going issue which continues to cause political and ethical controversies. Although there is no direct stipulation acknowledging capital punishment in the constitution, there is controversy on the existence of indirect basis. The Art. 12. I. can not be regarded as an indirect provision if it is interpreted to have criminal punishments stipulated by written law. As the supreme Court and the Constitution Court are supporting the capital punishment which seems unconstitutional, legislative examination is inevitable. Considering the fact that the Constitution is neither for nor against the death penalty positively, it is possible to abolish it by enactment of a law and thus, constitutional amendment would not be needed.

Sometimes, the misjudgement of imperfect human can not be avoided because capital punishment is decided by a judicial officer, human. Dreiinstanzen system has been adopted to prevent misjudgement. However the possibility of misjudgement can not be entirely excluded in the judgement by a judicial officer as the judgement of a lower court and a higher tribunal depends on the specific criminal cases. And in case of capital punishment executed by misjudgement, it leads to a cruelty result which has not ways to recover the damage. There is an opinion that dangerousness of misjudgement is lacking in persuasiveness because of insufficient demonstration for the abolition of capital punishment. However, also, there is an opinion that the abolition of capital punishment in case of misjudgement is persuasive with reality. In this case, even if other punishments are discussed separately, once capital punishment is executed, it can be irrevocable unjustice because a nation itself commits a crime. According to this, I would like to find out causes of misjudgement in the criminal justice system through the cases of advanced countries, such as United states, Japan, which are rich in studies and case analysis related to misjudgement, and introduce their efforts to prevent misjudgement in this paper.

In every society, citizens must decide how to punish criminals, uphold the virtue of justice, and preserve the security of the community. In doing so, the members of society must ask themselves how they will punish those who carry out the most abhorrent of crimes. Many common responses to such a question is that death is an acceptable punishment for the most severe crimes. But to draw some theoretical distinction between a crime that deserves incarceration and a crime that is so heinous that it deserves capital punishment is subject to three errors. First, what possible line could be drawn? To decide on a particular number of deaths or to employ any standard would be arbitrary. Second, the use of a line would trivialize and undermine the deaths of those whose murderers fell below the standard. Third, any and all executions still are unjust, as the State should not degrade the institution of justice and dehumanize an individual who, although he or she has no respect for other human life, is still a living person. Simply put, all murders are heinous, all are completely unacceptable, and deserve the greatest punishment of the land; however, death as punishment is inappropriate. Also, while this article arrives at the conclusion that the death penalty is an inappropriate form of punishment, I have not offered an acceptable alternative that would appease those who believe capital offenders deserve a punishment that differs in its quality and severity. This is a burden that, admittedly, I am unable to meet. I finally conclude that the death penalty is unjustified retribution. This is the only claim that can effectively shift the intellectual paradigms of the participants in the debate. The continued use of the death penalty in society can only be determined and influenced by the collective conscience of the members of that society. As stated at the outset of this article, it is this essentially moral conflict regarding what is just and degrading that forms the backdrop for the past changes in and the present operation of our system of imposing death as a punishment for crime.

기계가공으로 인한 사고는 작업자에게 치명적인 경우가 많다. 이러한 사고는 완벽한 가공지그을 통해 대부분 예방이 가능하지만 제품설계초기 후가공과 양산 공정은 고려되지 않고 설계되어 기계가공 시 재해로 연결되는 경우가 빈번히 발생하고 있다. 사형주조법은 수작업으로 손쉽게 제품을 생산하는 장점을 가지는 반면 치수오차가 다른 양산공정 보다 크다는 단점을 가진다. 이런 사형 주조품을 기계 가공할 때 제품의 치수편차로 인해 불안전한 고정및 과다한 절삭, 제품이탈, 공구파손, 장비와 공구의 빠른 수명감소 등의 다양한 문제가 발생 하지만 사형주조의 특성상 개선하기 어려운 문제로 인식되고 있다. 본 연구에서는 원형의 용기형태의 제품을 사형주조 후 기계가공 하는 것을 금형으로 대체하기 위한 셸몰드법을 제시하고 셸몰드로 만든 셸주형으로 주조함으로서 표면조도 평균 $Ra9.94{\mu}m$의 기계가공에 준하는 표면을 구현하였다. 외형의 정밀한 제품을 대량 생산하여 가공공정의 간소화 및 평균 두께 편차를 줄임으로서 제품파손 및 제작 시 발생할 수 있는 안전사고예방에 긍정적인 영향을 주었다. 기계가공전 제품의 치수정밀도를 높여 안전성, 생산성향상, 가공 공정단축, 환경개선 등을 이 가능함을 확인하였다.

Capital punishment is a system which is not finished simply as one of interim penalty but does away with one person's existence eternally. It is not only opposite to the existential humanism but also contrary to social welfare's goal like social integration. Therefore, this study tries to find out the issues related to capital punishment and further tries to draw out the rightness of capital punishment abolition by critically reviewing the capital punishment system on the basis of the value and philosophy of correctional welfare. In brief, capital punishment is possible only when we negate the inviolable fundamental right which is called life right, and deny the human life existence which surpasses space and time. As long as we can not deny the macroscopic viewpoint to search out the basis of human behavior in the social system which is called culture and society, capital punishment system is contrary to the philosophy of welfare that total society is responsible for guiding members of society to pursue self realization on the basis of value like social solidarity and human dignity. Also, it is against the objective of correctional welfare to head toward special prevention by positive correction and rehabilitation. Capital punishment system ought to be abolished properly.

지하방수로는 도시의 지하에 대규모 수로 터널을 시공하여, 도시 지역에 발생한 집중 호우를 초기에 배제하여 제내지 침수 피해를 줄이는 목적으로 사용되는 대표적인 구조적 홍수 피해 경감 대책이다. 효과적으로 침수 피해를 줄일 수 있을 뿐만 아니라, 특히 지하에 설치되어 토지 수용에 대한 부담이 줄어들기 때문에 일본 등지에서 최근 주요 홍수 방어 대책으로 활용되고 있다. 지하방수로 유입부는 크게 접근수로, 유입구, 수직 갱도(vertical shaft)로 구분되며, 접근 수로를 통하여 유입된 흐름은 유입구를 통하여 가속된 후 수직 갱도로 유입되게 된다. 따라서 지하방수로의 배제 능력을 평가하기위해서는 유입구에서의 유량 및 흐름 특성을 정확히 평가하는 것이 매우 중요하다. 나선식 종경사형 유입구(inclined spiral intake)는 지하방수로 유입구 중 가장 일반적으로 사용되는 형식으로 나선식 유입구의 한 형태로 유입구의 외측 또는 중앙선을 따라서 일정한 경사를 주어 사류 유입 흐름을 유도함으로서 유량 배제 효율을 높인 형태이다. 나선식 종경사형 유입구도 일반적인 나선식 유입구와 마찬가지로 접근수로 수위를 측정하여 유입량을 예측할 수 있다. 본 연구에서는 수리 모형 실험을 통하여 나선식 종경사형 유입구에 대한 수위-유입량 관계를 검토하였다. 평탄한 입구를 가지는 안내벽이 있는 형식의 유입구 모형을 이용하여 수위-유입량 관계를 검토하였다.

Bead type and hollow fiber type catalyst (HFC, Hollow Fiber type Catalyst) was prepared by $La_{0.1}Sr_{0.9}Co_{0.2}Fe_{0.8}O_{3-{\delta}}$ (LSCF1928) perovskite powder catalyst which showed excellent methane complete oxidation characteristics through previous studies. The HFC have a cylindrical shape with an empty interior, and pores can be formed through Phase inversion method so the specific surface area can be remarkably improved. In the case of the bead type catalyst prepared by adding Methyl Cellulose (MC), $SrCO_3$ was produced in addition to the original catalyst composition of LSCF1928 due to the reaction of $CO_2$ emitted from MC and Sr of the catalyst. In the case of the HFC, a single phase perovskite structure was obtained without impurities. The HFC calcined at $700{\sim}900^{\circ}C$ showed pore structure of finger-sponge-finger structure, and 99.9% oxygen conversion rate was achieved through complete oxidation of methane at $475^{\circ}C$. Air gap and spinning pressure condition were changed to control the HFC pore. 2 cm air gap and 7 bar spinning pressure showed the best catalytic performance and achieved oxygen conversion rates of more than 70.65%, 93.01%, and 99.99% at $425^{\circ}C$, $450^{\circ}C$ and $475^{\circ}C$, respectively.

Thermal management is important for enhancing the performance and durability of polymer electrolyte membrane fuel cells (PEMFCs) and is taken into account in the design of PEMFCs. In general, cooling pates with circulating liquid coolant (water) are inserted between several unit cells to exhaust the reaction heat from PEMFCs. In this study, computational fluid dynamics (CFD) simulations were performed to characterize the uniform cooling performance of parallel multipass serpentine flow fields (MPSFFs) that were used as coolant flow channels in PEMFCs. The cooling performances of conventional serpentine and parallel flow fields were also evaluated for the purpose of comparison. The CFD results showed that the use of parallel MPSFFs can help reduce the temperature nonuniformity, and thus, can favorably enhance the performance and durability of PEMFCs.

Cellulose triacetate (CTA) polymer among cellulose esters were used for preparing hollow fiber membranes by phase separation method to investigate the gas permeation properties. To endow gas separation properties, 1,4-dioxane and LiCl were used as additives in the polymer dope solution. The spinning conditions including spinning temperature were controlled to form an active skin layer on the hollow fiber surface. Scanning electron microscopy was used to examine morphology of surface and cross section of the prepared CTA hollow fibers. The gas permeation performance of CTA hollow fiber membranes showed $P_{CO2}$ = 17 GPU and ${\alpha}_{CO2/N2}$ = 48.
