고에너지적 Nd-Fe-B계 소결자석 제조를 위한 펄스자장 성형시, 금형 및 다양한 성형조건이 자석의 이방화율 향상에 미치는 영향에 대하여 조사하였다. 일반적으로 butterfly, disk or coin 형태의 자석을 제조하는 방법으로는, 종축자장성형법(Axial Die Press, ADP)을 이용하여 최종제품의 near-net shape으로 성형 및 소결하는 방법과, 횡축자장성형법(Transverse Die Press, TDP)을 이용하여 blick or cylinder 형태로 제조한 후 여러 단계의 가공공정을 거쳐 최종제품으로 제조하는 방법이 적용되고 있다. 그러나, ADP의 경우 분말의 자장정렬 후 성형단계에서 성형밀도가 증가함에 따라 배향의 틀어짐 현상이 증가하므로 이방화율 향상의 한계가 있어 (BH)$_{MAX}$+iHc=54 이상의 자석은 제조되기 어렵고, TDP의 경우 고이방화 자석의 제조가 가능하나 복잡한 형상의 제품을 직접 성형할 수 없어 성형/소결 후 복잡한 가공공정을 거쳐야 하므로 재료의 손실뿐만 아니라 고가의 가공비용이 소요되므로 경제적인 문제점을 갖게 된다. 반면에, 펄스자장 종축성형방법(PDP)은 3T~5T의 펄스자장을 이용하여 분말의 정렬 및 성형을 동시에 수행함으로써 TDP보다 향상된 배향율이 얻어질 수 있으며, ADP으로만 실현 가능한 복잡한 형성의 자석을 near-net shape으로 제조가 가능한 잇점이 있다.다.

Nowadays Internet is the greatest and most participating media of prompting expression with 37 million users in Korea. Internet enables collective communications between social members and contributes to form sound public opinions and to develop democracy while it has negative aspect to distribute massively crime by illegal posting which is forbidden by the Criminal Act. Criminal actors who involve to diffuse information on Internet consist of three categories of information provider, user and internet service provider. Illegal posting generated on Internet is originated from IP and the criminal regulation on it is useless and meaningless because of its countless of users and ambiguous boundary with liberty for expression. Accordingly, the only criminal policy means to prevent danger by illegal posting on Internet is to regulate ISP which saves illegal posting and mediates contacts among users. In spite of it, legislation to regulate ISP is unprepared. The prudent legislative review should be done. And it should be accordance with the doctrines of propriety and vagueness of the principle of "nulla poena sine lege".

The purpose of this dissertation is finding the meaning and form of Euthanasia, Considering by Criminal law that the core of the debate over the 'pros and cons' of euthanasia, And seeking measures about needs of currently Euthanasia legislation and institutional establishment. Through the remarkable progress, today's medical science makes to cure the Incurable patients, and artificially prolong human life by life-support system. These changes of Healthcare Environments extending a permissible range of Euthanasia over the series of criminal discussions about Euthanasia. And medical treatment has been discussed from negative side to positive side. So, In the current legal system, seeking for realistic measure is demands of the times behind the penally and ethical problems. Therefore, I will study the needs of legal system and reestablish values about Respect for Human Life.

Dang-Chin feldspar powder with the mean particle size of 9.1 $\mu\textrm{m}$ was added to the synthesized mullite powder with the particle size of +325∼-200 mesh and the powder compact was prepared by PLPP(pressureless powder packing method). Densification behaviors were observed in sintering temperature range of 1200∼1400$^{\circ}C$. The binder solution of 4% PVA was infilterated into packed powder to the suitable strength. The PLPP method makes it possible to form compacts without clay as plasticizer. Therfore there was no defect caused by phase transition after sintering. Additionally, we observed the dense microstructure by the melting of feldspar. When the mullite compacts with feldspar of 30% were sintered at 1300$^{\circ}C$-4 hrs, we obtained the dense microstructure with zero water absorption and porosity <1%. When these compacts were sintered longer than 4 hrs at 1300$^{\circ}C$ or higher than 1400$^{\circ}C$, the examggerated grain growth of mullite was observed.

Even after the Constitutional Court decided on August 23, 2012 that the provisions of abortion were constitutional, discussions on the abolition of abortion continued. The controversy about abortion is not only happening recently, but it has already existed since the time when the Penal Code was enacted, and it shares the history of modern legislation with the Republic of Korea. Legislators whom submitted amendment while insisting upon the eradication of abortion in the process of enacting criminal law at that time, presented social and economic adaptation reasons as the core reason. From then on, the abolition of abortion has been discussed during the development dictatorship, but this was not intended to guarantee women's human rights, but it was closely connected to the national policy projects of "Contraception" and "Family Planning" of the Park's dictatorship. Since then, the enactment of the Mother and Child Health Law, which restrictively allow artificial abortion, was held on February 8, 1973, in an emergency cabinet meeting that replaced the legislative power after the National Assembly was disbanded. It became effected May 10th. The reason behind the Mother and Child Health Law that included legalization of abortion in part was that the Revitalizing Reform at that time did not allow any opinion, so it seem to be it was difficult for the religious to express opposition. The "Maternal and Child Health Law" enacted in this way has been maintained through several amendments. It can be seen that the question of maintenance of abortion has been running on parallel lines without any significant difference from the time when the Penal Code was enacted. On August 23, 2012, the Constitutional Court decided that the Constitutional Opinion and the unonstitutional Opinion were 4: 4. However, it was decided by the Constitution without satisfying the quorum for unconstitutional decision of the Constitutional Court. This argument about abolition of abortion is settled for the the time being with the decision of the constitutional inconsistency of the Constitutional Court, and now, the National Assembly bears the issue of new legislation. In other words, the improved legislation must be executed until December 31, 2020, and if the previous improved legislation is not implemented, the crime of abortion (Article 269, Paragraph 1, Article 270 of the Criminal Code) Article 1 (1) will cease to be effective from 1 January 2021. Therefore, in the following, we will look into the reason of the Constitutional Court's constitutional discordance adjudication on criminal abortion(II), and how it structurally differs from the previous Constitutional Court and the Supreme Court. After considering key issues arised from the constitutional discordance adjudication(III), the legislative direction and within the scope of legislative discretion in accordance with the criteria presented by the Constitutional Court We reviewed the proposed revisions to the Penal Code and the Mather and Child Health Act of Korea(IV).

Force balance method is employed to predict forging information such as forging load, tool pressure and normal stress at the surface of tangential velocity discontinuity. The incipient stages of deformation for the plane strain forging of rectangular billets in V-shaped dies of different semi-angles are analysed. To construct an approximate model for the analysis of deformation by the force balance method in the incipient deformation stages, slip-line field is used. When the deformation mode by slip-line method is the same as that by force balance method, the slip-line method and the force balance method give identical solutions. The effects of die angle, coefficient of friction, billet geometries and deforma- tion characteristics are also investigated. In order to verify the validity of force balance analysis, the rigid-plastic finite element simulation for the various forgig parameters are performed and performed and find to be in good agreement.

The Korean Society of Law and Medicine has faithfully played the role of professional academic organizations last 20 years in terms of academic activities, accumulated achievements, diversity, professionalism, and influence on academic circles. The Korean Society of Law and Medicine and the Journal of Medical Law serve as a platform for academic information and exchange of opinions on medical law. Medical law began in the midst of increasing conflicts and disputes caused by medical malpractice and the enactment and legal coercion of medical care as pressure on medical workers. It tried to find a way to coexist with each other through the encounter and convergence of medicine and law. Medical criminal law extends from traditional crimes in the realm of life and body protection to bioethics violations caused by the development of biomedical technology, corruption and economic crime in the medical field. Medical law has evolved into a comprehensive legal area dealing with legal issues raised in medical treatment, healthcare, bioethics, and life sciences technology. On the legal side, medical law is not independent legal areas. It is overlapping with traditional law areas such as civil law, administrative law, criminal law, social law, civil and criminal procedure law. However, it is now established as a convergence study in medicine, bioethics, life science, as well as in various fields of law. It has become an area where collaboration is needed with the field of law, medicine, ethics, sociology and economics. Medical criminal law has undergone a dynamic development over the last two decades. The development of medicine and medical technology provides new and innovative methods of diagnosis and treatment. The achievements and risks of revolutionary developments in biotechnology, genetic engineering and medicine coexist. While there is a dazzling achievement that mankind has hoped for: combating disease and improving health, it also creates unwanted side effects and risks to humans. There is a need to reconsider ethical and legal principles. The discovery and development of patient identity and autonomy has changed the medical doctor-patient relationship. Furthermore, it was complicated by the triangle relationship of patients, medical doctors and insurance. Legal matters are also complicated. This is why the necessity of legislation is emerging. Criminal punishment provisions are also required. The Medical Law and Biomedical Law are systematically and coherently deformed as mosaic-based legislation that takes place whenever there are social issues, citizens' needs, and medical organizations' interests, rather than sufficient enactment and revision procedures. It needs a complete overhaul, and this is possible through interdisciplinary collaboration which is the strength of The Korean Society of Law and Medicine.

Das Leben des Embryos ist als solche ein Rechtsgut, das einen durch das Strafrecht hinreichend $gesch{\ddot{u}}tzt$ werden sollen. Daher versteht es sich von selbst, $da{\ss}$ auch bei der Schwangere die ihren eigenen $empf{\ddot{a}}ngenen$ Embryo beseitigenden Handlungen nicht $unbeschr{\ddot{a}}nkt$ gebilligt werden $k{\ddot{o}}nnten$. Es $k{\ddot{o}}nnte$ bei der Schwangere wegen ihrer $Interessenverh{\ddot{a}}ltnisse$ mit ihrem Embryo z. B. endlosen deren Verantwortlichkeiten nur die $Erlaubnism{\ddot{o}}glichkeiten$ ${\ddot{u}}bergelegt$ werden. Wie der Bundesverfassungsgericht schon ${\ddot{u}}berzeugt$ hat, $k{\ddot{o}}nnte$ das Leben des Embryos keinen vom Strafrechtschutz $ausschlie{\ss}enden$ Teil anerkannt werden, sondern nur in besonderen $F{\ddot{a}}llen$ ausnahmsweise dessen Verletzung erlaubt werden. ${\ddot{U}}ber$ die Reichweite der ausnahmsweisen anerkannten Erlaubnisse gegen einer Rechtsgutsverletzung sollte es im Allgemeinen $abh{\ddot{a}}ngig$ unter Zeitraum und Umwelt konkret ausgefargt werden. Daher kann eine konkrete Diskussion ${\ddot{u}}ber$ Rechtsfertigungsgrund des Schwangerschaftsabbruchs nur erstenmal anfangen, nachdem ein strafrechtlicher Schutz des Embryolebens $pr{\ddot{a}}zis$ ausgeforscht wird. Bis jetzt hat das Strafrecht das Rechtsgut als Leben des Embryos zu leicht bewertet und damit hat die Strafe des Schwangerschaftsabbruchs zu niedrig bestimmt. Die niedrige Strafe des Schwangerschaftsabbruchs $enth{\ddot{a}}lt$ die Gefahr, die die Erlaubnisreichweite des Schwangerschaftsabbruchs ungerecht ausdehnt. Die Handlung der Schwangere sollte minder bestraft werden, um das Sebstbestimmungsrecht der Schwangere hoch $w{\ddot{u}}rdigen$ zu $k{\ddot{o}}nnen$. Letztlich braucht der Versuch des Schwangerschaftsabbruchs zu bestrafen. Der Versuch und die Vollendung ${\ddot{u}}ber$ die Verletzung des Embryolebens sollten deren Unterschiede im ihren Unrechtsgehalt anerkannt werden, weil der Normzweck des Schwangerschaftsabbruchs im Schutz des Lebens des Embryos besteht. Und damit in den $F{\ddot{a}}lle$, die in Folge des versuchten Schwangerschaftsabbruchs die Schwangere verletzt oder gestorben wird, $k{\ddot{o}}nnten$ die Meinungsstreiten $aufgeh{\ddot{o}}rt$ werden.

According to dictionary, the meaning of protection is "guard and protect" that means protecting the Protectee's safety in case of sudden attack or various accident and Security means all protecting activity including Protectee and place where he is in or will be as comprehensively meaning of safe. As you see in the definition, Protection and security is the act to protect or will to protect from a security-threat act. A security-threat act can be discussed in the range of the concept of a criminal act in Criminal Law. A security-threat act is based on criminal act in Criminal Law, we are going to review such a security-threat act in a point of view in a sphere of learning in today's remarkable a brain-neuro science and cognitive science based on cognitive psychology, and to use an analysis on such a security-threat act to make a foundation for a establishment of the scientific preventive social security countermeasure. To do so, First of all we are going to review a security-threat act based on criminal act in Criminal Law in a point of protection police logic view. Next, we are going to introduce how cognitive science understand about act of man before we analyse a threat act as one of an act of man in cognitive science point of view. Finally, we are going to discuss the need of cognitive scientific analyse in order to establish the Scientific Preventive Social-security Countermeasure at the same time we are going to analyse a threat act in a cognitive scientific view.
