        샤피 V-노치 충격 하중-변위 곡선으로부터 얻은 균열정지하중을 이용하여 원자로압력용기강의 균열정지파괴인성(KIa)을 예측할 수 있는 방법을 모색하고 그 타당성을 고찰하였다. 샤피충격 하중-변위 곡선으로부터 얻은 균열정지하중값의 변화는 특성온도로 보정된 지수함수의 형태로 잘 표현될 수 있었다. 특성온도 TPa=2kN은 실험적인 무연성천이온도(TNDT) 및 T41 J과 높은 상관성을 나타냈으며, 원자로압력용기강의 균열정지파괴인성을 표현하는 새로운 특성온도로 사용할 수 있을 것으로 판단되었다. 또한 균열정지하중값의 변화는 파면으로부터 측정된 안정균열길이의 변화와 매우 높은 상관성을 나타내었다. 따라서 무딘 노치를 갖는 시편에 대한 계장화샤피충격시험을 통하여 균열정지하중 및 안정균열길이를 측정하믈써 비교적 정확하게 원자로압력용기강에 대한 하한값의 파괴인성치(KIa)를 평가하는 것이 가능한 것으로 판단되었다.

        The aim of this study is to confirm the importance of a more immediate advanced cardiac life support (ACLS) through a comparative analysis of the results of cardiopulmonary resuscitation (CPR) according to the occurrence place of cardiac arrest in tertiary emergency department. The subjects were 493 patients who had received CPR in Chosun university, Emergency Medical Department, between April 2013 and March 2015. The subjects were categorized into three groups according to the occurrence place of cardiac arrest: pre-hospital, in-emergency room, and in-ward. We conducted a clinical analysis of the results. During the period, 493 cardiac arrest patients underwent CPR, 63 patients (12.8%) were discharged alive and 41 patients (8.3%) got a good score on the cerebral performance category (CPC). Concerned occurrence place of cardiac arrest, 11.3% (16 patients) of the in-emergency room group (total 288 patients) were discharged alive. Also, 9.4% (27 patients) of the In-emergency room group got a good score on the CPC. In the other two-group cases, 7.1% (10 patients) of pre-hospital group (total 141 patients) and 6,2% (4 patients) of in-ward group (total 64 patients) got a good score on the CPC. These results indicate that both the rates of alive discharge and a good CPC score of the in-emergency room group are higher than in out-of-emergency room. This difference might be due to the fact that patients could get the more immediate ACLS by emergency medicine doctors if cardiac arrest occurs in emergency room than other places.

        The purpose of this research is to compare between past and present resuscitation outcome of cardiac arrest patients in one emergency department. A clinical analysis of 429 cases of CPR performed in one emergency department from April 2013 to March 2015 was conducted. Then we compared this with previous paper that were written in same emergency department in 2004. During the period, 429 patients received resuscitations. Between the two studies, all patients under CPR were increased 2.27 times (94.33 pts/years to 214.5 pts/years). As the cause of cardiac arrest, traumatic cardiac arrest increased to 30.1% form 24.1%. Cardiogenic cardiac arrest showed highest survival rate in two studies, and the ratio was increased from 6.8% to 15.2%. VF/VT showed highest survival rate in two studies, and the ratio was increased from 8.8% to 20.7%. In this study, At least who once became ROSC patients was 260 people (60.6%), permanent surviving patient was 34 people (7.93 %), patients with CPC score 1-2 was 26 people (6.06%). The survival rate of patients with cardiac arrest has increased compared to the past. But in-hospital cardiac arrest survival rate is still low so it is necessary to increase the recovery rate of cardiogenic arrest survival rate to increase the permanent survival rate and good prognosis patients.

        Today, those cases which drunk people are to be put to violent to police officers that perform the public service in the night are going to frequently. If a drunk man did a assault and intimidation to police officers that are performing a public service, he can be punished by public affairs executive interference sin, but if he tried only an abuse, he can be arrested and punished by contempt. But there is criticism that abuse the public authority for this. Whether arrest of flagrant delictor is legitimate, it is to be judged on the basis of the time of arrest situation, and police officers must have an accurate understanding of the requirements of arrest. For this, the law and judicial precedent must give an accurate guide line to police officers in order that able to arrest the culprit and to crush the crime. However, if there are different conclusions that the cases of two of judgment there is no difference, precedents of the court is not the role of the criteria was firmly in the investigation field of clear distinction, the side is that rather it was confusing. In order to solve this confusion, I think that “anxiety of flee or destroy evidence” shall be excluded as the requirements of a flagrant delictor, and if not a serious case or a urgent case need to determine whether there is a need to arrest.

        Cervical epidural injection is a common treatment for management of neck, shoulder, and upper extremity pain. Although several complications are possible, cardiopulmonary arrest and intraventricular pneumocephalus are rare serious complications, mainly occurring when the dura has been punctured. We report on a case of cardiopulmonary arrest and intraventricular pneumocephalus after cervical epidural injection with loss of resistance technique using air. After performance of cardiopulmonary resuscitation for 30 minutes, a pulse was regained; however, the patient’s mental status was coma. Despite receiving conservative treatment, the patient ultimately died without recovery of consciousness.

        In oocytes from different species, MPF, a complex of Cdk1 and cyclin B, is the master regulator of cell cycle. The activity of MPF is regulated by the phosphorylations mediated by Wee1B kinase and Cdc25B phosphatase. Although a regulation of MPF activity by these inhibitory phosphorylations are well established, a dogma in the cell cycle is that MPF activity is regulated by the dynamics of cyclin B during the metaphase II (MII) arrest (also known as CSF arrest). However, growing evidences suggest that Wee1B-mediated Cdk1 phosphorylation is also critical to trigger the progression of cell cycle during the onset of anaphase. Therefore, in the present study, we investigated the role of Cdc25B phosphatase during MII arrest. Cdc25B is present in MII arrested oocytes as a hyperphosphorylated form and disruption of its function either by antibody or siRNA injection induces the progression of cell cycle to interphase. Moreover, the hyperphosphorylated form, which has been known as an active form of Cdc25B, is dephosphorylated during the anaphase onset. Interestingly, this dephosphrylation occurred ahead of cyclin B degradation. Conversely, overexpression of Cdc25B prevents metaphase to anaphase transition induced by calcium stimulation. Therefore, our findings provide novel paradigm in cell cycle that MPF activity during metaphase arrest is regulated by the balance between Cdk1 inhibitory kinases, Wee1, and the counteracting phosphatases, Cdc25. When cells exit from metaphase, Cdc25 is inactivated and Wee1 is reactivated and thereby Cdk1 kinase activity is rapidly and transiently decreased. This initial decrease of Cdk1 activity is further promoted by the proteolytic degradation of cyclin B, which ensures irreversible progression of cell cycle to interphase. Thus, the concerted effort of phosphorylation/dephosphorylation of Cdk1 and synthesis/degradation of cyclin B play roles in fine-tuning the activity of Cdk1 during metaphase to anaphase transition.

        Keeping the intact germinal vesicle (GV) is essential for maintaining the capacity of mammals including human. It is maintained by very complex procedures along with folliculogenesis and is a critical step for getting competent oocyte. So far, a few mechanisms involved in folliculogenesis are known but GV arrest mechanisms are largely unrevealed. Cyclic AMP, a adenosine derived substance, have been used as inhibitor of germinal vesicle breakdown as a putative oocyte maturation inhibitor. In this study, we examined the potency of adenosine as GV maintainer and a possible signaling mediator for that. A1, A2b, and A3 were detected in cumulus cells of cumulus enclosed-oocyte (CEO). Intact of germinal vesicle was not kept like in follicle but the spontaneous maturation was inhibited by exogenous adenosine. It is inhibited with concentration dependent manners. Intracellular calcium level of cumulus was extensively increased after adenosine treatment. Based on these results it is suggested that one of the pathway for GV arrest by adenosine and its receptors is calcium mediated signaling pathway in CEO.

        The Korean Constitution and the Korean Criminal Procedure Code provide the emergency arrest exception for the warrant requirements. The investigative authorities can arrest suspects without an arrest warrant issued by a judge if there is "probable cause" to believe that a suspect has committed a felony and if there is concern to believe that the suspect may destroy evidence or attempt to escape. In the case of an emergency arrest, the Criminal Procedure Code does not require that an arrest warrant be filed within 48 hours but it only requires that a detention be filed, therefore, the warrantless arrest without any judicial control is legitimatized for at least 48 hours. As a result, the investigative authorities tend not to pursue the arrest on the warrant, but depend on the emergency arrest because it is free of any warrant requirement and gives them much time to interrogate the suspect without any judicial control. In addition, the investigative authorities have developed two kinds of convenient systems to avoid the warrant requirement. The first is "voluntary accompaniment," which is the Korean version of the U.S. Terry stop system. The second is "investigation of relevant persons" who voluntarily appear before the authorities following the authorities' request to come to the police station although they are not a suspect. Since these two systems are not officially a compulsory measure, the constitutional restrictions for an arrest warrant do not attach. In particular, the authorities often proceed these two systems first, try to acquire informations from citizens, then arrest citizens if they are not cooperative. This Article is to review two Korean Supreme Court decisions to deter these two investigative authorities' tactics. The Decisions of July, 6, 2006 provides strict requirements of permissible "emergency arrest" of the "relevant persons" who voluntarily appear before the authorities. The Decisions of September, 8, 2006 stablished that if the individuals who are asked to voluntarily accompany the officer to the police station are not given the "freedom to leave" at any time, as a practical matter, the "voluntary accompaniment" is an illegal arrest.

        According to newly revised Korean Commercial Law, 1991, several amendments on the maritime liens as a special legislative rights duly performed so as to make an equity with mortgates of the ship. Consequently, it is also noteworthy that claimants of the maritime lien should know how to secure their legal rights on the ship. Such a legal practice is performing in accordance with the doctrine and principles of the law of forciable excution without court order. This paper, therefore, intends to study specific legal practice for exercising legal rights on the ship by due process of law.
