최근 3.20 전산망 장애 등 기업을 대상으로 한 대규모 사이버공격이 빈번히 발생함에 따라, 기업의 정보보호 수준을 강화해야 한다는 요구가 증가하고 있다. 이런 상황에서 보안 기능을 서비스로 제공받는 형태의 클라우드 서비스, SecaaS(Security as a Service)가 기업의 정보보호 수준을 강화하기 위한 비용효과적인 방법의 하나로 대두되고 있다. 본 고에서는 SecaaS에 대해 간단히 설명하고, 이를 구현하기 위한 기능 요구사항과 국내 외 관련 솔루션 및 서비스 개발현황 등을 소개하고자 한다.

오늘날 정보와 정보시스템은 조직의 핵심 자원 중의 하나이다. 이러한 자원이 효율적이고 효과적으로 활용되지 못하면, 조직의 전략적인 목표 달성에 지장을 초래하게 된다. 이처럼 중요한 자원을 효율적이고 효과적으로 관리하기 위해서는 정보시스템에 대한 적절한 통제가 수립되고 이러한 통제가 적절하게 작동하는지를 점검하고, 여기에 대해서 조언을 해 주는 기능, 즉 정보시스템 감사 기능을 수립하여 실행하는 것이 필요하다. 그러나 정보시스템 통제/감사 체계를 도입하더라도 그 수준은 조직에 따라서 달라질 필요가 있다. 본 논문에서는 이러한 정보시스템 감사/통제 성숙수준을 평가할 수 있는 한 모델인 CobiT의 기본 개념과 적용 사례에 대해서 알아본다.

The purpose of this study supplies the basic data to plan the optimum mental health service that is reflected needs of the elderly people with mental illness by checking how their demographic-sociological distinctive feature and function level have an effect on their needs of mental health service by being absent situation of a study of the elderly people with mental illness. As results of analysis, the residental type, the disease period, and the decision person of admission-discharge control of demographic-sociological distinctive feature is much effect on needs of programs and also effect commonly on the needs of the health promotion program and the discharge support program. Generally, the function level of the elderly people with mental illness is favorable and the order of function level is the group activity program, the counseling program, and the resource network program.

This study was to examine the causal relationships among extraneous variables, social participation, and life satisfaction among the elderly persons. This study analyzed 4014 elderly persons out of 2010 KLoSA. The path analysis and mediating effects were examined by AMOS. Except educational level, family income, health status, functional capacities, K-MMSE, and CES-D10 were direct effects on the life satisfaction among the elderly persons. The mediating effects of causal meeting activities, leisure activities, and membership based activities were significant on life satisfaction. This study proposed implications of improving life satisfaction for the elderly through utilizing of social participation activities.

It is essential to guarantee high reliability of embedded real-time systems since the failure of such systems may result in large financial damage or threaten human life. Though many researches have devoted to fault tolerant mechanisms, most of them are object-level fault tolerant mechanisms that can detect errors occurred in a single object and treat the errors in object-level. As embedded real-time systems become more complex and larger, there exist faults that cannot be detected by or tolerated with object-level fault tolerance. Hence, system-level fault tolerance is needed. System-level fault tolerance examines the status of a system whether the system is normal or not by analyzing the status of objects. When an error is detected it should be capable of locating the fault and performing an appropriate recovery and reconfiguration action. In this paper, we propose RobustRTO(Robust Real-Time Object) that provides object-level fault tolerance capability and RMO(Region Monitor real-time Object) that offers system-level fault tolerance capability. Then we show how highly dependable fault tolerant systems can be modeled by RobustRTO and RMO. The model is presented based on real-time objects.

우리나라는 1990년대에 접어들면서 분권화는 피할 수 없는 시대적 요청으로 모든 부문의 주요과제가 되고 있다. 분권화의 핵심은 행정 권한과 역할의 지방 분권화를 의미하며, 지방 분권의 수준은 무엇보다도 행정 기능과 사무 배분을 어떻게 하느냐에 따라서 결정된다. 지금까지 원자력 안전 규제 기능은 중앙 정부가 독점하고 있었기 때문에 향후 중앙 집권화된 규제 기능을 어떻게 합리적으로 또 효과적으로 지방 정부에 이양하느냐가 원자력 안전 규제 제도의 최적화에 중요한 과제가 되고 있다. 따라서 본 연구는 중앙 정부와 지방 정부간 원자력 안전 규제 기능의 합리적$\cdot$효과적 배분을 위한 원칙과 기준, 유형과 모델을 제시하고 그에 따른 적실성 있는 기능 분담 대안을 모색하는데 있다.

The purpose of this study was to investigate activity participation level and functional disability based on ICF for the elderly aged over 65 years. Subjects were 100 senior citizens. We performed data collection using Korean Activity Card Sorting(KACS) and World Health Organization Disability Assessment Schedule 2.0(WHODAS 2.0). Data were analyzed using descriptive statistics, Pearson's correlation, multiple regression. As a result of the survey of activity participation levels, retained level of activity participation of instrumental activity was highest at 75.06%. Among the WHODAS 2.0 sub-domain, 'getting along with people', 'participation in society' had the most difficulties and 'self-care', 'life activities' were the lowest. An analysis of the correlation between the activity retention rate and functional disability showed that there was a significant negative correlation. Significant factors influencing functional disability were activity participation level of social activity, instrumental activity and main work(retirement). We confirmed that activity participation level was important factor on functional disability. Further, we need standardization study for generalization.

The purpose of this study is to develop cognitive scaffolding tools and to explore their effects on integrated science process skills of high school students. For this purpose, we developed cognitive scaffolding tools including one kind of classroom instruction for training integrated process skills and two kinds of individual learning materials that students can selectively study according to their level of inquiry ability. In addition, we developed hypothetico-deductive inquiry tasks as a tool to investigate the level of students on the integrated process skills for pre-test and post-test respectively. In order to verify the effectiveness of the cognitive scaffolding tools, we conducted inferential statistics on the pre-and post-tests of the experimental group and control group to examine statistical significance of students' inquiry level change depending on the usage of the cognitive scaffolding tools. We also produced Wrightmaps based on Rasch model to compare the change of inquiry ability depending on usage of the cognitive scaffolding tools. As a result, the experimental group using the cognitive scaffolding tools showed a significantly higher scores in all the components of integrated process skills namely, designing inquiry, collecting data, analyzing data, and forming conclusion than the control group. In addition, students who used cognitive scaffolding tools improved their inquiry ability and showed a distinct transition to higher level in each component of the integrated process skills. The results of this study suggest that high school students need cognitive scaffolding to alleviate or eliminate the functional barriers they face in conducting scientific inquiries.
