N/A We performed 17 intraarterial scintigraphies in six patients with recurrent cervix cancer. With Seldinger method, the agent (four different radiopharmaceuticals) was perfused at the same speed of infusion of anticancer drugs (25 cc/hour) through internal iliac artery. There were four different radiopharmaceuticals; I-131-Lipiodol, Tc (Technetium)-99m-HSA (Human Serum Albumin), Tc- 99m-Sucralfate and Tc-99m-MAA (Macroaggraegated Albumin). We evaluate the distribution pattern of radioactivity by the use of ratio of Tumor/Extratumor uptake (T/ET ratio). Our results reveals that Tc-99m-MAA scan showed the highest T/ET ratio and the other were not ideal agents for intraarterial therapy of recurrent cervix cancer. In conclusion, an ideal radioisotope and tracer which can block capillary, for example MAA, should be re-evaluated or produced in order to treat the patient with recurrent cervix cancer.

국제법상 compétence de la compétence원칙에 관한 연구

유형정(Yoo Hyung Jeong) 국제법평론회 2016 국제법평론 Vol.0 No.44

In the past decade, the States have increasingly shown a tendency to conclude ante hoc consent on judicial dispute settlement mostly by way of inserting compromissory clause into their bilateral or multilateral treaty which allows either of the parties can bring the dispute to the international judicial body unilaterally. Moreover, the trend of the institution of proceedings before the international court has shown that the dispute parties have increasingly seized the court resorting to the unilateral application. It is expected that the number of challenges to the court’s jurisdiction would increase since the clauses are normally comprehensive and wide. In other words, it is a matter of whether or not the treaty covers a subject matter brought before the international court. Focusing on this new trend surrounding the international court, it is worthwhile to revisit compétence de la compétence. In order to resolve the international disputes properly and effectively, it is necessary that the court should be assured of its power to exercise compétence de la compétence as widely as possible. Therefore, this study will mainly focus on three subjects as following: firstly, by historically studying the existing discussion and jurisprudence, it will trace the flow of the development of compétence de la compétence; secondly, it will examine the sources of compétence de la compétence as the inherent power of the international court and its limits; thirdly, it will suggest the future matters regarding compétence de la compétence which should be dealt with in international law. Compétence de la compétence, the power to determine its own jurisdiction, is well established as a general principle by international jurisprudence and reflected in most of the statutes of the international courts. As mentioned above, compétence de la compétence is the essential factor for court to control the proceeding before it. In other words, the court could prevent its process from being obstructed and maintain its authority based upon this power. According to ICJ jurisprudence, the power for the court to determine its jurisdiction is inherent and it is emphasized by the feature of an judicial institution which is based upon the constituent instrument defining its jurisdiction and operation. In principle, it cannot be said that compétence de la compétence exercised by the international courts is absolute and unconditional like a domestic court. Based upon the consensual jurisdiction, the court could be deprived of the power if there were the clause of reservation, such as the clause contaire or the self-judging clause. This conclusion would appear to be natural if no party submitted the dispute to the court on the basis of such clauses. However, once either party brings the matter which the other considers reserved, it is valid that the court could exercise compétence de la compétence to determine whether or not it would fall within the scope of its jurisdiction. This is because there would not be any agreement on the reservation. Considering the purpose of the compromissory clause and the intention when both parties made a conclusion of the treaty, the court should take a teleological approach to make the dispute resolved. On the other hand, admitting the widest competence of the international court could raise concerns about excessive exercise of the power, or ultra vires to widen its jurisdiction because it is rarely found that the international court dismissed its jurisdiction in practice. Furthermore, the fact that the hierarchy of the international judicial system is absent could lead the parties to be unwilling to resort to international judicial bodies. Examining ICJ judgments, it rejected reviewing a decision of jurisdiction by other tribunals because the award was final and it confirmed that the tribunals hav

The purpose of this study was aimed to explore the scientific activities of the Severance Union Medical College(SUMC) during the Japanese colonial period (1910-1945). It is well known that western medicine was introduced by Dr. H. N. Allen since 1885, and expanded by Dr. O. R. Avison at the beginning of the 20th century. In Nov. 14th, 1914, there search department of SUMC had started as a stone laying in the field of medical research by the missionary doctors. And thereafter, the academic activities of SUMC had been extended through the case conferences, and research meetings of each department until 1945. The activities from SUMC physicians were published in the medical journals named China Medical Journal, Chosun Medical Journal, Mansen no Ikai, The Journal of SUMC, Korean Medical Journal(Chosun Euibo), etc. The lists of the articles published in those journals were analysed periodically following the name of the authors as well as the each basic and clinical department.

레일레이 및 라이시안 페이딩 채널 환경 내의 시역전 펄스의 공간 특성

유형하(Hyung-Ha Yoo),고일석(Il-Suek Koh) 한국전자파학회 2009 한국전자파학회논문지 Vol.20 No.7

본 논문에서는 Rayleigh 및 Ricean 채널 환경 아래에서의 시역전 시스템의 펄스 특성을 해석적으로 분석한 후 이를 Monte Carlo simulation을 통하여 검증한다. 시역전 통신 방식은 시역전 어레이를 구성하는 안테나들이 송신단에서 보낸 신호를 받은 후 이를 시간 축에서 역전시켜서 데이터와 함께 보내는 통신 방식이다. 채널 특성 변화는 시간에 따라 아주 느리다고 가정하고 시역전 어레이를 구성하고 있는 안테나 사이의 공간이 충분히 크지 않아서 각 안테나에 도달하는 신호들 간에 상관도가 있는 경우를 고려한다. 두 페이딩 채널에서 시역전 펄스가 공간상 좁은 영역에 존재함을 보이고 또 이 펄스의 안정성이 안테나의 수에 비례함을 증명한다. We perform an analysis of the characteristics of the time-reversal pulse in Rayleigh or Ricean fading channel environments. We verify it by using Monte Carlo simulation. In a time-reversal system, each antenna in the time-reversal array receives signals from the transmitter and reverse the received signal in the time axis and then resend it to the original transmitter. We assume that the channel characteristics varies very slowly and the spatial separation between the antennas is not large. Hence the signals received by each antenna are correlated. In this paper, the effect of the correlation on the time-reversed pulse is examined, which includes the spatial properties of the time-reversal pulse such as the focus size, and spatial power distribution.

The WTO Member States have the sovereign right to take measures for protecting its national environment. However, it must not serve as a trade barrier. If so, the measure should be justified under the requirements of GATT XX, which provides the general exceptions. The provision has the two-tiered system. To justify a particular measure, it should meet the requirements of paragraphs (b) or/and (g), covering necessary measures to protect human, animal or plant life or health and relating to the conservation of exhaustible natural resources. Then, that measure should satisfy the requirements of its Chapeau. The Chapeau provides that a measure should not be a means of arbitrary or unjustifiable discrimination or disguised restriction on international trade. Appellate Body emphasized that the Chapeau should be interpreted in the contextual perspective of the measure and related policies. It is applied not to the intention of the measure but to execution of the measure. It, therefore, functions as a means of preventing the Member States from abusing such right. On the other hand, there is no agreed standard to apply the chapeau. It means that judgments can be varied based on contexts of cases. Thus, it is important to analyze WTO jurisprudence to acknowledge the trend of interpretation. According to WTO jurisprudence, the measure should be transparent and flexible as applied and a Member State is required to have multilateral negotiations with other Member States before taking a measure. Also such measure includes the goal relating to protecting the environment. This study can suggest the guidelines for the Member States to take unilateral measures and avoid disputes over their own measures.

국제판결 및 중재판정의 이행강제방법에 관한 고찰

유형정 ( Hyung Jeong Yoo ) 연세대학교 법학연구원 2009 法學硏究 Vol.19 No.2

Recently, the rate of submitting international disputes to international courts has increased, and this illustrates an expansion in the use of legal instruments for settling disputes. This tendency has arisen since international courts may be one of the most objective and reasonable instruments for resolving conflicts, and decisions are binding under international law and impose on State Parties the obligation of compliance with international judgments and awards. Although unsuccessful parties are expected to comply with judgments and awards proprio motu, it is difficult to ensure prompt compliance by those unwilling parties. Besides, it seems that the process of compliance after decisions can cause another conflict because parties are required to carry out negotiations in order to put intoeffect judgments and awards. Although a delay in negotiations to comply should not unconditionally be considered as non-compliance, as no-time-limit negotiation can damage the interests of a winning party, instruments to obviate delays in compliance are also needed. Therefore, it is important to identify the definition of a delay in compliance considered to be non-compliance and when it should be enforced. To force unwilling parties to comply, it is necessary to define the fundamental principle under international law. By examining general international law overall, this study enunciates the grounds of such an obligation. As specific methods of enforcing compliance are absent under international law, it seems appropriate to emphasize the security of compliance. Self-help is traditionally used as such a method. It might be effective and directive, but is limited to be taken under international law, so that it cannot be a useful method. Thus it is necessary to seek legally based methods in addition topolitical ones. This study looks into two levels of instruments-internationally and municipally. First, the 2001 ILC Draft can impose the international obligation on State Parties to comply with international judgments and awards so as to violate the obligation ofState responsibility. And by enforcing judgments and awards through national courts, it may be a direct method of putting them into effect. There are few cases where there is no compliance. However, a delay in complying can turn into a potential non-compliance case, and that may result in damage to the authority and effectiveness of international courts. From this perspective, it is necessary to hold an active discussion regarding judicial methods to secure compliance with international decisions.

원발성 간암의 67Ga Scan 소견 ; 혈관조영술 소견과의 비교

유형식(Hyung Sik Yoo),이종태(Jong Tae Lee),박창윤(Chang Yun Park),서정호(Jung Ho Suh),김명준(Myung Joon Kim) 대한핵의학회 1989 핵의학 분자영상 Vol.23 No.1

N/A The relationship between angiographic findings and those of 67Ga scan was evaluated in 30 patients with primary hepatocellular carcinoma diagnosed by either pathological examination or laboratory, radiologic findings. Twenty-three cases revealed hot activities on 67Ga scan and definite tumor stains on angiography. Main findings of 67Ga scans of 7 cases were isoactivity in 5 and cold area in 2, 5 of which revealed faint or no tumor stain on angiography. Cold areas within the primary hepatocellular carcinoma were noted in 9 cases by 67Ga scan. In 6 cases these were due to tumor necrosis. Remaining 3 cases had arterioportal shunt, portal vein thrombosis and one had necrosis as well. These results indicate that gallium uptake of primary hepatocelluar carcinoma seems to be relatively correlated with tumor stains on angiography. It is well known that the necrotic portion of primary hepatocellular carcinoma does not uptake gallium and it's the main cause of cold areas on 67Ga scan. And we suspect that the hemodynamic changes of primary hepatocellular carcinoma such as 1arge arterioportal shunt, portal vein thromosis may cause the decreased activity on 67Ga scan.
