The amount of electric energy used in a vehicle will be increased continuously. The increment of electric power demand causes interest on new higher power system such as 42V Power Net. Furthermore, the necessity for development of energy storage device is highlighted recently. Bidirectional nm Converter is one of the important parts in 42V power system. Therefore, this paper proposes bidirectional Cascade Buck-Boost DC/DC Converter which can satisfies required specifications in 42V power system The operation principle is described along with simple control method, and experimental results on a 500W prototype are provided.

This study investigated the relationship between musical understanding and expression, the purpose of music education. It also intended to present the theoretical basis of integrated early childhood music education by examining into the necessity of it as a method to help young children with musical understanding and expression. The results of the study showed that either of the understanding and expression of music should be necessary and there is a mutual promotional relationship between them. It was found out that real musical understanding can be formed not by mechanical skill, but when the relationship between notes is understood with various experiences. Therefore an integrated early childhood music education became necessary as a principle of educational method to help young children with musical understanding and musical expression. Concretely it was found out to be necessary in terms of the characteristics, interest and concern of young children, the use and development of multi intelligence and the translation of the same knowledge into the same level.

This paper deals with metaphysical aspects of responsibility focusing on Hans Jonas's Das Prinzip Veranwortung as an attempt to further the discussion on the responsibility of scientists and engineers. After the examination on the necessity of new ethics reflecting the characteristics of contemporary science and technology, the philosophical foundation and major themes of Jonas's future-oriented ethics, i.e. responsibility ethics are analysed. Jonas argued new ethics should consider man and nature simultaneously based on the unification of being and what should be, and presented collectivity, continuity, and future-orientation as a basis of responsibility ethics. In conclusion, this paper suggests implications of Jonas's argument for science and technology ethics such as sustainability, precautionary principle, and responsibility of creator.

The application of the recent model-based control schemes for robot manipulators require the solution of problems concerning various aspects, from the mechanical design to the necessity of determining a robot model suitable for control, and of experimentally testing the control performances. For one solution, integration of SolidWorks with Simscape for designing and controlling robot manipulators is presented in this paper. The integration provides a platform for rapid control prototyping of robot manipulators without the need for building real prototypes. Mechanical drawings of a robot are first created using Solidworks and imported into the Simscape, where a robot is represented by connected block diagrams based on the principle of physical modeling. Simulation examples for 7-DOF SAM ARM made by Berrett Technology Inc. are testified to show effectiveness of the presented platform.

This study aims to point out what is the basic idea and principle of weed control in or-ganic farming. The korean organic agriculture gets a point in dispute on weed control, be-cause 1) they do not practice the Basic Standard of IFOAM and FAO/WHO Codex Guidelines(draft), and 2) Korean organic farming is defined quite differently from internationally recognized core aspects for organic agriculture. Organic farming, in Korea, is taken to mean just the replacement of chemical fertilizer by organic manure and a-voidance of agricultural chemicals without practicing on rotation, cropping system and so on. As a consequence, organic farmers in Korea are suffering from hard labor to control the weed. In the paper it is discussed on organical weed control method which are required in the Basic Standard of IFOAM and guidelined in the Organic Production Principles of FAO/WHO Codex draft, and furthermore the single or combination effect of those method are also discussed. In conclusion it is suggest the necessity, purpose, and effect of the introduction of the basic stan-dard to korean organic agriculture including organical weed control.

This paper gropes for advisable home management principle, named “philosophy of household management(PHM)”, which is presented to home managers. Philosophical thought about household can give fundamental under-standing about family circumstances. So home manager can get better judgement about family things and house affairs. In that sense, this paper is expected to provide family members with the ground of thought: how to help each members’ self-completion, to make better relationship among family members as well as between families and society, and to manage all environmental resources. As the paper researches new field of home management, it presents academic significant of PHM. Then, it explains why ‘Han consciouseness’-the native philosophy of Korea-is adequate for foundation theory of PHM, and what ‘Han philosophy’is. In conclusion, the paper argues necessity of view for home management, and discusses (1) view of human being, (2) view of economic activity, and (3) view of natural environment as family resources.

The industrial products to use single phase inverter are raised the necessity of power quality improvement, such as AC Motor Driver, Lighting, Renewable energy power converter. Also, it is increasing that applied the single phase multilevel inverter for high quality power at renewable energy power converter. Especially, the photovoltaic multilevel inverters have at least more than two DC_Link and more than one DC/DC Converter. This paper proposes a triple output DC/DC Converter with one switch for photovoltaic multilevel inverter. The proposed converter has advantages of low cost and volume because it has one switch. The operation principle of the converter is analyzed and verified. A prototype is implemented to verify of the proposed converter.

The interdisciplinary study explores the discussion of actual infinity between Georg Cantor and Roman Catholic Church. Regarding the actual infinity, we first trace the theological background of Cantor by interpreting his correspondence and major works including ${\ddot{U}}ber$ die verschiedenen Standpunkte in bezug auf das aktuelle Unendliche(1885) and Mitteilungen zur Lehre vom Transfiniten (1887), and then investigate his argumentation for two points at issue: (1) pantheism and (2) inconsistency of the necessity with freedom of God. In terms of mathematics and theology, Cantor defined the actual infinity(aphorismenon) as characterized by (1) the transfinite infinity(Transfinitum) and (2) the absolute infinity(Absolutum). Transfinitum is conceptualized here in mathematical terms as a multipliable actual infinity, whereas Absolutum is not as a multipliable actual infinity. The results imply that Cantor's own concept of Transfinitum and Absolutum is adequate for Roman Catholic theology as well as mathematics including the reflection principle.

본 논문의 목적은 공연자로서 배우의 몸을 통해 발현되는 '자발성'의 원리를 살펴보고 그 적용 가능성을 고찰하는 것이다. 이를 위해 동시대 배우들이 인물을 창조하기 위한 접근 및 훈련과정에서 흔히 직면하게 되는 문제점을 비판적인 관점에서 논의하고 그 대안으로 배우의 행동과 텍스트가 추구하는 본질적 기능과의 상호보완적 관계를 규명함으로써 연기예술의 토대를 이루는 핵심 원리를 재고하고자 한다. 본 연구에서 중점적으로 논의하는 자포라를 비롯한 마셜, 브루엘, 존스톤, 보알 등의 연기지도자들은 자발적 반응으로써 행동 과정의 중요성을 강조한다. 이들의 공통된 관점을 종합할 때 변화를 추구하고 이를 달성하고자하는 텍스트의 본질적 기능은 역설적으로 배우가 무대 위에서 필수적으로 수행해야 할 임무와 면밀하게 닿아있는 것이며, 이는 곧 예술가로서 배우 스스로가 선택하고 결정한 표현에 대한 책임과도 직결된 것이다. 본 논문은 이러한 과정을 바탕으로 분석과 행동의 상호보완적 관계 속에서 배우의 몸이 자발적 상태에 이르기 위한 접근 방법을 보알의 관점을 중심으로 살펴보고 그 실효성을 제언하고자 한다.

우리나라에서 통상 사용하는 협진의 의미는 동일한 의료기관 내에서 서로 다른 진료과목의 의사가 환자를 함께 치료하는 경우로 이해된다. 그렇기 때문에 협진은 다양한 의료관여자들이 각자의 전문성에 의거하여 역할을 분담하여 환자를 치료하는 의료팀의 양상을 띠게 된다. 또한 의료팀 내 다른 진료과목의 의사는 동등한 지위에서 각각 전문성에 의거하여 수평적 분업을 하게 되므로 협진은 분업의 원칙에 따라 법적 책임이 분배된다. 대법원도 "여러 명의 의사가 분업이나 협업을 통하여 의료행위를 담당하는 경우 먼저 환자를 담당했던 의사는 이후 환자를 담당할 의사에게 환자의 상태를 정확하게 알려 적절한 조치를 할 수 있도록 해야 한다."고 하여 의료팀을 이루어 환자를 함께 치료하는 경우를 인정하고, 의사의 협진의무에 대하여 판단하고 있다. 다수의 진료과목이 있는 의료기관 내에서 서로 다른 진료과목의 의사가 분업이나 협업을 통하여 의료행위를 담당하게 되는 협진의 경우, 환자를 담당했던 의사는 환자의 상태에 따라 협진 여부를 결정하여야 하며, 이후 환자를 담당할 진료과목의 의사에게 환자의 상태를 정확하게 알려 적절한 조치를 취하게 하여야 한다. 협진을 하게 된 후임 의사 또한 환자에 대한 치료 종료 시까지 협진을 요청했던 전임 의사에 대하여 환자의 상태와 관련된 치료사항을 적극적으로 고지하고 서로 소견을 교환하여야 할 것이다. 다만 협진의 필요성에 대한 결정은 당시 환자의 상태에 따라 판단이 이루어져야 하는 것으로, 모든 경우에 협진의무가 강제되는 것이라고 단언할 수는 없다. 그리고 협진의 필요성에 대한 결정에 있어서 과실이 존재하는지 여부는 의사의 주의의무 판단에 대한 법리가 적용될 것이다.
