고전압 전류 특성의 낙뢰는 안테나를 통해 지상에 설치된 이동 통신 기지국으로 도입될 수 있으며, 이를 방지하기 위한 장치가 서지 어레스터이다. 본 논문에서는 서지 어레스터의 개념, 종류, 동작 원리, 설계 및 제작 등을 검토하고, 이를 기반으로 현재 국내외에서 이용되고 있는 이동 통신 서비스인 셀룰라, GSM 및 PCS 등과 차세대 이동 통신 서비스인 IMT-2000의 기지국에 적용 가능한 서지 어레스터들을 설계하였다. 초기 설계된 서지 어레스터들은 고주파 3차원 구조 시뮬레이터 상에서 특성 예측을 위한 컴퓨터 모의 실험과 서지 어레스터의 전자기적 특성 개선을 위한 내부 구조 최적화 작업이 수행되었다. 서지 어레스터의 최종 설계도를 기반으로 실제 IMT-2000 기지국용 4분의 1 파장 단락 스터브 방식의 서지 어레스터를 제작하였으며, 전자기적 전송 특성 측정과 낙뢰 전달 테스트를 수행하여 제작된 서지 어레스터의 성능을 측정하였다. 측정 결과, 전압 정재파 비는 1.05 이하, 삽입 손실은 -0.035 dB이하, 상호변조 특성은 -150 dBc 이하의 특성을 얻었으며, 잔여 전압 특성은 7∼ll V 정도의 특성을 보였다. The lightning with high voltage and current can enter the basestations for mobile communication through their antenna. The device which can protect the basestation against the lightning, is surge arrestor. In this paper, the concept, kind, operating mechanism, design and fabrication of surge arrestor were studied. Based on the studied data, variable surge arrestors were designed for the current mobile communication service like a cellular, GSM and PCS and the next generation mobile communication like a IMT-2000. Computer simulation for the prediction of their characteristics and inner structure optimization for the improvement of their electrical characteristics were carried with high frequency 3D structure simulator. Quarter wave short stub surge arrestors for IMT-2000 were fabricated with their final design and then the measurement of electrical characteristics and the lightning test were executed. As a results of measurement, we obtained below 1.05 of VSWR, -0.035 dB of insertion loss, -150 dBc of intermodulation and 7∼ll V of residual voltage.

행정상 강제집행제도의 입법적 개선에 관한 고찰

김연태(Kim Yeon tae) 충북대학교 법학연구소 2016 法學硏究 Vol.27 No.2

The system of administrative execution is a means to secure fulfillment of individual administrative obligations to ensure realization of public interests and legal execution by the state. Hence the system of administrative execution is one of the core elements that characterize the system of public law under the dual division of public and private law. Administrative obligations must be performed and a certain extent of administrative effectiveness must be ensured by means of compulsion of performance among others, in order to deal with failures to perform those obligations. Simultaneously, the rights of citizens must not be violated by abusive use of the rights of administrative execution. How to construct the system of administrative execution differs by histories and legal systems of each nation. Republic of Korea accepted the German legislation of administrative execution through Japan. Yet while Germany has secured a self-sufficient and complete legal system of administrative execution under general law, Korea uses a system that regulates mainly using individual law from a point of view that is protective of human rights, although it possesses some regulations pertaining to general law. Under the current legal system of administrative execution, non-performances of administrative obligations are, at times, not met with appropriate means of execution. The current system is also criticized of its lack of systematic structure as legislations are carried out individually according to different interests of government departments. Moreover, even under the individual legal regulations, the conditions and limits of administrative execution are often unclear and the control mechanisms of adjective law about administrative execution are at times insufficient. Therefore, legislative improvements are necessary in order to better protect the rights and interests of citizens. In order to improve the current legal system of administrative execution, this paper recommends that the legal justification, conditions and limits of administrative compulsory execution be clarified by regulating the fundamental principles and general provisions under general law, complementally specifying in a limitative manner the appropriate means to achieve the purpose of the legislation under individual laws, and establishing detailed regulations that consider the distinct content and purpose of individual laws.

의무이행소송과 예방적 금지소송의 쟁점 검토 - 법무부 행정소송법 개정시안을 중심으로 -

Das Justizministerium hat nach ein Jahr langen Erorterungen einen Anderungsantrag des Verwaltungsstreitverfahrensgesetzes gestellt, in den die Verpflichtungsklage und die vorbeugende Unterlassungsklage eingefuhrt werden. Die Verpflichtungsklage ist eine gebotene Klageart immer dann, wenn mit der Klage die Verpflichtung einer Behorde zum Erlaß eines Verwaltungsakts im Sinne von § 2 Abs. 1 Nr. 1 Verwaltungsstreit- verfahrensgesetz begehrt wird. Mit der Verpflichtungsklage kann sowohl die Verurteilung zum Erlaß eines bestimmten Verwaltungsakts (Vornahmeklage) als auch - insbesondere bei Ermessensentscheidungen der Verwaltung - die Verurteilung der Behorde zur Verbescheidung eines Antrags auf Erlaß eines Verwaltungsakts in einem fur den Klager gunstigen Sinn unter Beachtung der Rechtsauffassung des Gerichts begehrt werden (Bescheidungsklage). Der vorbeugende Rechtsschutz gegenuber drohendem Verwaltungsakt ist mittels einer vorbeugenden Unterlassungsklage zu bewerkstelligen. Eine solche Klage ist allerdings nur dann zulassig, wenn die Verweisung auf die Moglichkeit eines repressiven Rechtsschutzes mittels einer Anfechtungsklage nicht ausreicht. Die vorbeugende Unterlassungsklage gegen einen Verwaltungsakt kann daher nur in besonderen Ausnahmenfallen in Betracht kommen, insbesondere wenn die faktische Vorwirkung des Verwaltungsakts schon so erheblich ist, daß ein Abwarten der eigentlichen Entscheidung fur den Klager unzumutbar ist. Grundsatzliche Bedenken gegen die Statthaftigkeit der vorbeugenden Unterlassungsklage gegen einen Verwaltungsakt schlagen nicht durch. Insbesondere folgt aus dem Gewaltenteilungsgrundsatz nicht, daß der Rechtsschutz gegen konkrete Verwaltungsmaßnahmen stets nachtraglich zu sein habe. Auch die Umgehung des Vorverfahrens ist keine Frage der Statthaftigkeit. Die Ausfuhrungen beziehen sich speziell auf die umstrittene Rechtsfrage der Verpflichtungsklage und der vorbeugenden Unterlassungsklage.

3차원 프로파일 데이터 및 도로포장 균열 깊이 변화량에 따른 도로포장의 균열검출 노이즈 제거 기법 성능분석

김연태(Yeon-Tae Kim),이문섭(Moon-Sup Lee) 한국산학기술학회 2022 한국산학기술학회논문지 Vol.23 No.3

본 연구에서는 도로포장 3차원 프로파일 데이터의 노이즈 제거 기법과 객체의 특징을 부각하는 방법에 대해 연구하였다. col 노이즈 제거 기법을 적용한 경우 종방향의 균열이 부각되게 표현할 수 있었다. 특히 종방향의 성질을 지니는 미세균열을 두드러지게 표현할 수 있었다. val 노이즈 제거 기법을 적용한 경우 횡방향의 균열이 부각되게 표현할 수 있었다. 특히 cal 노이즈 제거 기법과 마찬가지로 횡방향의 성질을 지니는 미세균열을 두드러지게 표현할 수 있었다는 점에서 col, val 노이즈 제거 기법을 유의하다고 판단하였다. 따라서 두 기법의 장점을 이용하여 관계식을 도출해내었고 관계식을 적용하여 3차원 데이터의 노이즈를 제거하지만 종방향 균열과 횡방향 균열을 부각되게 하는 3차원 데이터 표출 방식을 도출할 수 있었다. 이 외에 pan, diagonal, All around 노이즈 제거 기법은 도로표면의 실제 높낮이가 등고선의 형상으로 표현하였다. 이는 실제 표면상의 높낮이가 변화하는 구간이 임계값을 넘는 부분임을 예상할 수 있는데 3차원 레이저 스캔 카메라에서 획득하는 3차원 데이터는 측정된 깊이 영역에 대한 상대적인 비를 흑백 영역으로 0~255의 범위 내에 변화값으로 표현하기 때문에 나타나는 한계점이라고 판단되었다. This research studied the noise removal technique of the road pavement 3D profile data and the method of highlighting the characteristics of the object. When the col noise removal technique was applied, the longitudinal cracks were expressed prominently. In particular, microcracks with longitudinal properties were expressed remarkably. When the val noise removal technique was applied, it was possible to express the cracks in the transverse direction to emphasize. In particular, it was found that the col and val noise removal techniques were significant as they were able to remarkably express microcracks with lateral properties similar to the cal noise removal technique. Therefore, a relational expression was derived using the strengths of the two techniques. Moreover, a three-dimensional data expression method was derived that removes the noise of the 3D data by applying the relational expression but emphasizes the longitudinal and lateral cracks. In addition, in the pan, diagonal, and all-around noise removal techniques, the actual height of the road surface is expressed in the shape of a contour line. It is expected that the section in which the height changes on the actual surface exceeds the threshold. It was found to be a limiting point that appears because it is expressed as a change value.

Environmental Administrative Litigation is a control procedure enforced by courts on illegal environmental administrative actions in order to protect the environment. A court`s possible solutions for environmental disputes are limited not only by its authority which is restricted to the interpretation and application of relevant Statutes but also by the fact that a lawsuit may only proceed on satisfaction of its jurisdictional elements. Not unlike general administrative litigation, the standing requirement in environmental administrative litigations performs its function to filter administrative actions to be enforced by the courts. In other words. the standing :requirement determines the scope and limitations of judicial review in such administrative actions. Thus one must recognize the need to expand the court`s power for purposes of environmental protection while acknowledging the limitations of the court`s power based on concepts of separation of power. According to Korean judicial precedent, people residing within the Environmental Impact Assessment (EIA) area are de facto presumed to have standing in lawsuits while people residing outside the area are required to prove their standing. Such judicial precedent is considered to be a step-forward in comparison to previous case law which completely denied standing to people residing outside the EIA area. While maintaining this line of legal policy, going forward, it will be necessary to find a more rational legal base of reasoning. Given the seriousness and distinctiveness of environmental issues, traditional litigation measures or legal principles may be insufficient solutions. To overcome this difficulty, it is worth to review the Verbandsklage of Germany or The Public Trust Doctrine of the U.S. as possible candidates to deal with the weaknesses of our litigation system which is based on personal relief to settle environmental conflicts.

의무이행소송의 쟁점에 대한 고찰 -독일에서의 소송상 쟁점을 중심으로-

김연태 ( Yeon Tae Kim ) 고려대학교 법학연구원 2014 고려법학 Vol.0 No.72

행정현실의 변화와 고양된 국민의 권리의식을 반영하기 위하여 행정소송법 개정의 필요성이 학계와 실무계에서 지속적으로 제기되어 왔었다. 대법원이 2006. 9. 국회에 제출한 행정소송법 개정의견, 법무부가 2007. 7. 마련하여 2007. 11. 국회에 제출한 개정안, 그리고 법무부가 다시 2011. 11. 행정소송법 개정위원회를 구성하여 논의를 거쳐 2013. 3. 입법예고 한 개정안 등 그 동안의 행정소송법 개정작업에서는 현행 권리구제절차(거부처분 취소소송이나 부작위위법확인소송)의 불완전성을 해소하고 분쟁의 발본적·일회적 해결이 가능한 제도로서 의무이행소송을 도입하는 것에 대하여는 의견 일치를 보여주었다. 물론 의무이행소송제도의 구체적인 형성에 있어서는 여러 쟁점에 대하여 의견이 일치되지 않은 것도 있었다.이 글에서는 2013. 3. 입법예고 된 법무부 개정안을 중심으로 개정안 마련 과정 중에서 논의되었던 의무이행소송 제도의 쟁점에 대하여 간략히 살펴보고, 우리보다 먼저 의무이행소송을 도입하여 그에 관한 판례와 학설이 집적되고 정리되어 온 독일의 의무이행소송 제도를 개관하고, 독일에서의 구체적 쟁점과 적용례에 대하여 고찰함으로써, 우리 의무이행소송 제도의 올바른 정립을 위한 시사점을 찾고자 한다. 행정소송의 체계와 입법 규율의 차이에 대한 이해를 바탕으로 하여 우리의 법과 현실에 맞는 우리의 의무이행소송이 정립될 수 있기를 기대한다. The necessity of amending the Administrative litigation Act has been raised continuously to both the Academic community and the Practice field in order to reflect the changes in the reality of Administration and the elevation of the nation`s right consciousness. Thus far, revision processes of the Administrative litigation Act have reached a common understanding about introducing Fulfillment of Obligation Litigation as a legal system which is capable of settling the instability of right remedy procedures(revocation of refusal disposition or litigation for affirmation of illegality omission) and of solving disputes in a radical and decisive manner. The efforts made so far to revise the Administrative litigation Act include : The revised comments of the Administrative litigation Act presented to the National Assembly by the Supreme Court in September 2006; The amendment of the Act written by the Ministry of Justice in July 2007 and presented to the National Assembly in November of the same year; and the ministry`s effort to form a Administrative Litigation Act Revision Committee in November 2011 to discuss an amendment and make a pre-announcement of legislation for it in March 2003. Yet in some cases differences in opinions also emerged concerning the detailed formation of the Fulfillment of Obligation Litigation system. Based on the amendment that Ministry of Justice made the pre-announcement of legislation for, this paper will briefly examine the issue of the Fulfillment of Obligation Litigation system that was discussed during the process of writing the amendment. After that, it will provide an overview on the Fulfillment of Obligation Litigation system in Germany where it was introduced before Korea and judical precedents and theories concerning Fulfillment of Obligation Litigation are accumulated and well-organized. Later, this paper will cover the consideration on the concrete issues and cases of application in Germany. By carrying out these tasks, this paper will attempt to seek the implication for the right establishment of the Fulfillment of Obligation Litigation system for Korea. It shall be my desire to see the establishment of Fulfillment of Obligation Litigation system which corresponds to the law and social reality in Korea based on the thorough understanding of the difference between administrative litigation system and legislation rule.
