  • 클라우드 환경의 대규모 인프라 구조에서는 응용프로그램들과 디바이스의 공유로 인하여 불법적인 접근권한 문제가 빈번하게 발생하기 때문에 이러한 공격에 적극적으로 대응하기 위해서는 상황별로 대비가 가능한 강화된 접근통제 시스템이 요구된다. 우리는 대규모 인프라 환경에 기반한 보안등급과 릴레이션 개념의 개체 속성 기반 접근통제 모델을 제시하였다. 본 모델은 주체와 객체에 무결성과 기밀성 등급을 부여하고 동일한 역할에 대해 서로 다른 서비스가 가능한 강화된 접근제어 특성을 가지며, 서비스와 관련된 릴레이션과 상태정보인 컨텍스트에 의해 역할과 권한을 배정함으로써 권한 관리의 유연성을 갖는다. 또한, 대학이라는 대규모 인프라 구조를 갖는 다중 서비스 환경에 적용한 응용 사례를 통하여 본 모델의 적용 가능성을 제시하였다.

  • For this study, inquiry-based learning program was developed for promoting elementary students' scientific justification activities based on their uses of scientific evidences. The program was applied to the 5th grade science class to examine the types of evidences and major features of scientific justification activities. Analysis of the data showed that the evidences used by students were classified into knowledge-based evidence, experience-based evidence and authority-based evidence. As for students' justification features, this study reports three major cases: a case evolving evidence and justification to become more valid and logical, as inquiry activities progressed, other case maintaining less valid and illogical evidence and justification, and final case revealing passive and reluctant participation in the inquiry activities. Overall, students' participation in scientific justification process became more valid and relevant, while there were some students who were unable to make the relevant relations between evidences and claims they made. The educational implications were discussed to consider more effective ways to improve the scientific classroom environment through social knowledge construction.

  • The sewing machine was the most widely-advertised item in mid-Victorian English periodicals. However, no historians have so far analyzed how English advertisers created the link between the domestic sewing machine and middle-class women, or what impact they may have had on gender relations. This paper treats sewing machines as a medium to enhance our view of gender and social history, consumer culture as well as material culture studies. Studying the advertisements of sewing machines reveals the traditional values and modern consumer culture of mid-nineteenth England, and also offers a sense for how advertisers expected people to react. Sewing machines could not only offer women aspiration and authority, but could also function as a timesaver through which a woman could attain a truly modern lifestyle. Buying a sewing machine for their wives symbolized their status as a breadwinner and a caring husband, as well as serving as an appreciation of their wives' domesticity. Sewing machines also provoked anxiety for both sexes because some believed that women would lose their morality and gender identity, whereas others believed that if relieved of domestic drudgery women would have time to educate themselves, which threatened to men and the gender hierarchy.

  • Although the demand and necessity for the facilities of nature environmental conservation and its utilization have been increased recently, the local governments has been experiencing difficulties to launch the facilities since there are no confirmed principles or guidelines for the direction of the facility and distinctions from the ordinary parks. In this regard, the aim of this paper is to provide the overall framework for establishing the facility by equipping checklists from planning to operational stage. The stages are disengaged into 5 steps of siting feasibility, planning, preliminary environmental assessment and environmental impact assessment, design, construction, and operation. This paper also include the recommendations to vitalize the existing facilities, of which expansion of educational program development; utilization of various manpower; provision of appropriate settings; strengthened monitoring; and increased public relations. Furthermore, it is suggested to consider the strengthened local characteristics, reviewing management plan at the stage of applying a new facility establishment to the concerned authority, fostering experts, and expansion of the facilities through restoration of environmentally damaged areas for a new facility.

  • The purpose of this study was to investigate the complementary gender division of housework in the Yangban ruling class of the Choson period. During the Choson period, genders were distinctly divided. It was generally regarded that women had to stay indoors and take care of household matters, while men, on the other hand, did not need to be concerned with housework because of the Confucian practice of "Naeoe". But homes in traditional society were considered as being at the center of production, so the study explores if women and men complemented each other through reviewed literature. As the results indicate, women and men in the Choson period complemented each other in some housework, even in the Yangban ruling class who maintained their authority by following the Confucian practice. From the findings, it can be concluded that the complementary relations between women and men in the Choson period should be emphasized as the origin of shared housework.
