The purposes of this study were to analyze the duplicated contents of 'Consumer life' area of Technology & Home Economics and other subject textbooks for the middle and high school students. It focused on textbooks compiled following the 2009 revised curriculum. To achieve the purposes of this study, "Technology & Home Economics I II", "Social studies I II", and "Ethics I II"textbooks for middle school and "Technology & Home Economics", "Social studies", and "Life & Ethics" textbooks for high school were analyzed based on the criteria for analyses of 'Consumer life' area. The results were as follows. First, the analysis of duplicated contents in Technology & Home Economics and other subjects (Ethics, Social studies) for middle school revealed that Technology & Home Economics textbook had the most proportion of 'Consumer Life' area, followed by Social studies and Ethics. The duplicated content elements in Technology & Home Economics, Ethics, and Social studies textbooks for middle school were 'consumer decision making', 'consumer information', 'economic impact of consumption', 'food life and sustainability', and 'consumption and sustainability'. Secondly, as a result of the content analysis of textbooks for high school Technology & Home Economics, Social studies, and Life & Ethics according to the criteria of analysis, it was found that Technology & Home Economics textbook had the most proportion of 'Consumer Life' area, followed by Life & Ethics and Social studies. The "content elements" 'food life management and consumption environment', 'desire of consumption', 'economic impact of consumption', 'changing factors and characteristics of consumer culture', and 'consumption and sustainability' were commonly found in all three textbooks. In this way, the 'Consumer life' area of Technology & Home Economics is thought to play a central role in teaching the 'Consumer Life' area because of its strength that contains detailed contents about consumer life for adolescent consumers who will apply it to everyday life. Based on the result of this research, it is needed to consider articulation of 'Consumer life' area of secondary schools for the future curriculum development of Technology & Home Economics to reduce the duplicated contents and to help the adolescents develop the ability to solve consumption problems they may encounter in real life and grow up to be rational adult consumers.

The purpose of this study was to analyze the core content of consumer area from 1st to 2009 revised middle school Home Economics textbooks with the aim of proposing guidelines. An in-depth content analysis was conducted twenty two Home Economics textbooks that have been used in middle schools, beginning with the first curriculum until the revised 2009 curriculum with word cloud. The major findings of this study were as follows; First, the first period of the textbooks emphasized thrift-related concepts such as budgeting and saving money. The second and third period in Home Economics textbooks focused on household work and resource management. From fifth period, the content of textbooks were emphasized learning how to find relevant information and making rational decisions as a consumer. The 2007 revised and 2009 revised period in Home Economics have focused on rational decision-making by adolescents, while taking into account environmental considerations. The content of textbooks now introduces students to the notions of ethical consumerism and eco-friendly consumption across domains such as clothing, food, and housing. The curriculum and content of textbooks in Home Economics should emphasize the concepts related to ethical consumption.

The purpose of this study is to propose the curriculum of consumer life field in Home Economics Education(HEE) to raise people who practice 'ethical consumption'. For this purpose, this study established the concept of ethical consumption through an academic review of the concept of ethical consumption first. Ethical consumption is to the practice of consumption that fulfills personal and social responsibilities to change human life happily. In this study, we find out how the consumer life area in the HEE curriculum has been educated and we propose how to teach the content of ethical consumption in HEE curriculum by critically examining the content of ethical consumption presented in current HEE textbooks First, in the HEE curriculum, the contents of the consumer life field have been presented since the first curriculum, and the qualitative change has gradually been made as the concept of the consumer culture, but responsible consumption and ethical consumption are not properly reflected in the education and the summit. Second, the revised HEE textbooks of 2015 is necessary to present concrete method of ethical consumption practice because it lacks definite definition of ethical consumption and presents only general contents. Third, the direction of HEE curriculum for ethical consumption practice is responsible and the goal of HEE curriculum is to raise awareness of social responsibility for ethical consumption practice. The contents of HEE curriculum for ethical consumption practice should be included in consumption and consumption, sustainable consumption, and ethical consumption.

본 논문에서는 자본시장의 변동성을 충분히 해명할 수 있는 가격결정모형이 정립되었다. 자본 자산의 가격은 세개의 위험에 대한 프리미엄의 총화임이 도출되었다. 이 세개 위험은 소비베타와 유사한 형태를 갖는 모수, 시장베타와 유사한 형태의 모수, 그리고 총국민생산의 성장률과 자산과의 공분산에 의하여 정의되는 모수이다. 이 모수를 각각 소비위험모수, 시장위험모수 및 생산위험모수라 할 수 있다. 자산의 가격을 결정하기 위하여 가격화(pricing)되는 체계적 위험이 세개라는 것은 중요한 함의인 것이다. 자산의 가격은 소비와 시장에 의하여 결정된다. 소비와 시장은 자체의 독립적 영역과 서로 상대에 대하여 상호작용하는 영역을 갖는다. 독립적 영역에서 생성되는 위험이 소비모수와 시장모수로 표상되며, 이 양자의 상호작용관계가 생산모수로 귀일한다.

This study analyzes the middle school Home Economics textbook's 'Adolescence consumption life' unit using framework of Education for Sustainable Development(ESD) to examine correlation with the current Home Economics ESD, and aims to provide the base data for the composition of the educational curriculum that can help the students cultivate the capability for leading sustainable life from the future oriented perspective and for the selection of educational contents. This study analyzes the 'Adolescence consumption life' unit in the Home Economics textbook of the 12 type revised curriculum of 2009. As for the analysis method, Romey's content analysis method is used to carry out in-depth analysis of the ESD content elements. The analysis demonstrates the following. First, content elements extracted commonly from the 'Adolescence consumption life' unit are analyzed with the ESD's criteria of analysis (environment, economic and social domain), which led to the composition with the sub content elements following 23 related topics. Secondly, content elements of 12 types of Home Economics textbook's 'Adolescence consumption life' unit used in middle school are analyzed in three domains, which led to social domain (68%), economic domain (58%) and environmental domain (40%) in the order mentioned. This focused on the role of the Adolescent-consumer on the active consumer that is presented in the 2009 revised educational curriculum, and it is possible to see that this is very closely related to the right to organize and to be active in terms of the human safety, consumption culture, social interest and group.

In this paper, when applying current-mode circuit design technique showing constant power dissipation none the less operation frequency, to the low power design of dynamic voltage frequency scaling, we introduce the low power current-mode circuit design technique applying MOSFET in sub-threshold region, in order to solve the problem that has large power dissipation especially on the condition of low operating frequency. BSIM 3, was used as a MOSFET model in circuit simulation. From the simulation result, the power dissipation of the current memory circuit with sub-threshold MOSFET showed $18.98{\mu}W$, which means the consumption reduction effect of 98%, compared with $900{\mu}W$ in that with strong inversion. It is confirmed that the proposed circuit design technique will be available in DVFS using a current-mode circuit design.

부채널 정보를 이용한 공격이 제안된 이후, 스마트카드와 RFID와 같은 저 전력 정보보호 장치 내부의 암호 프로세서에서 소비되는 전력을 분석하여 암호 연산에 사용된 비밀 정보를 알아내는 공격 방법은 가장 위협적인 물리적 공격 방법으로 알려져 있다. 하지만 측정된 소비 전력 신호를 시간 영역에서 분석하는 기존의 분석 기법들은 암호 연산 시점이 시간 축 상에서 동일하여야 된다는 단점을 가지고 있다. 제안하는 주파수 분석 공격 방법은 공격이 적용되는 장치에서 측정된 시간 영역에서 정렬되지 않는 신호를 Fourier 변환을 하여 주파수 영역에서 분석함으로써 기존 전력 분석 공격이 시간 영역에서 정렬된 소비 전력 신호를 필요로 하는 문제점을 해결하였다. UC Berkeley에서 제작된 능동형 RFID 모듈에 국내 표준인 ARIA 알고리즘을 응용프로그램으로 탑재하여 기존 전력 분석 공격과 제안하는 주파수 분석 공격을 적용하여 결과를 분석 하였다.
