조직 정보 시스템 보안을 위한 총괄 전략 프레임워크

박상서,Park, Sang-Seo 한국융합보안학회 2009 융합보안 논문지 Vol.9 No.2

정보 시스템 보안 체계를 보다 체계적으로 구축하고 효율적으로 운영하기 위해서는 보안에도 전략이 도입되어야 한다. 또한, 전략이 구현되어 성공적으로 작동하기 위해서는 조직 차원의 참여가 필수적이다. 하지만, 조직의 정보 시스템 보안 전략에 관한 연구는 아직까지 전략적 사고에 의한 보안 체계의 배치와 운영에 초점이 맞추어져 있어, 조직 전체를 움직이고 이끌기 위한 총체적 프레임에 관한 연구는 부족한 실정이다. 따라서 본 논문에서는 조직 차원의 보안 전략 수립에 활용할 수 있는 프레임워크를 연구한다. 이를 위하여 조직 차원의 전략 수립이라는 측면에서 총괄 전략의 개념을 도입하였으며, 총괄 전략이 갖는 4차원적 특성을 기반으로 정보 시스템 보안 총괄 전략을 구성하기 위한 프레임워크를 제시한다. Strategies have to be employed in information systems security in order to build and operate systems for information systems security in effective and structured manner. It is also essential for the entire organization to participate for successful implementation of the strategies and making them work. Current researches on information systems security strategy in organizations, however, have mainly been focused on deployment and operation of countermeasures based on strategic thinking and decision. In consequence, it is lack of research on overall frame for containing consideration factors required for moving and leading the whole enterprise for the holistic security purpose. Therefore, this paper proposes a framework for use in establishment of organization-wide information systems security strategies based on the concept of grand strategy from the traditional strategy research and on the four dimensional features of it.

유추적 관점에서 본 '포로 로마노'와 알도로시의 '세계극장'에 대한 고찰

Aldo Rossi explained Roman Forum as a significant urban artifact, because Roman Forum analogically showed not only an image of Roman Empire but also a figure of primitive design for its region. Thus the comparison and analysis between characteristics of Aldo Rossi's architectural works which are based on the theory of 'Analogical city' and the forums, the urban artifacts, was proceeded in this study. Consequently, it was discovered that Aldo Rossi had used his analogical thinking from the forum for his architectural languages such as gable roofs, square windows with depth, columns and so on. His analogical use of organizing spaces, such as courtyard type and pillar corridor type, has also shown that their types came from forum spaces. His analogical aspects of the forum: a space where urban images are analogically formed; were expressed in the 'Theater of Science' with the urban architecture form as the actor and the Theatre as the stage for analogical urban performances. Nevertheless, the expression of primitive design which divides the Roman Forum from other forums was actualized in 'the Theater of the World'. He not only analogically used types from Roman Forum in architectural design but also used boat in Water space, which decided the lifestyle and culture of Venice even before the civilization, to express the primitive design of Venice. Consequently, Aldo Rossi, by aiming the severance from the tradition, provided the possibility of explaining the newest modem type within the historical meaning by forming type which finds its continuance in history through 'the Theater of the World' and through analogical thinking along with the level of modern culture, to our urban architectural atmosphere that has lost its historical meanings.

This study was designed to investigate the effect of aerobic exercise on the brain waves and automatic nervous systems according to the time zone of the exercise. To this end, the difference according to the time of exercise was compared by dividing 18 male college students in their 20s into morning exercise group(n=9), and evening exercise group (n=9). The summary of the above results found that there was a significant increase of alpha waves in the left and right prefrontal lobe, left and right frontal lobe, left parietal lobe and right temporal lobe. However, there was no significant difference in the automatic nervous system (the average heart rate, SDNN, RMSSD, TP, LF, HF). It turned out that the aerobic exercise is effective in changing alpha waves of male college students, and there was no differences by the time zone of exercise. Accordingly, it is required to conduct regular aerobic exercise according to the individual``s lifestyle to ensure effective changes in alpha waves.

Mach를 기반으로 하는 분산 시스템에서 사용자의 편이성을 향상시키기 위해서는 전역 열람, 로그인 투명성 그리고 원격 디바이스 공유 등의 기능 추가가 요구된다. 전역 열람은 사용자에게 지역적으로 분산된 여러 화일 시스템을 하나의 계층적이고 통합된 구조로 보여주는 기능이다. 로그인 투명성은 사용자가 자신의 계정이 등록되어 있지 않은 임의의 호스트 또는 이에 속한 터미널에서 자신의 계정이 등록되어 있는 호스트로의 로그인이 가능하도록 한다. 마지막으로, 원격 디바이스 공유를 통해 사용자들은 분산 시스템 내에 존재하는 여러 입출력 디바이스들을 서로 공유할 수 있도록 한다. 본 논문은 386급 PC들이 Ethernet으로 연결된 Mach 기반 분산 시스템 환경 상에서 사용 편이성 향상에 필요한 세 가지 기능들을 구현한 방법에 관하여 기술한다. It is required that the facilities such as global view, login transparency and remote device sharing should be added for improving the user convenience on a Mach-based distributed system. Global view is a facility which provides the user with a hierachical and unified view of a group of geographically dispersed file systems. Next, login transparency is a facility which allows the user to login his host from any host which the user has no account or any terminal connected to it. Lastly, remote device sharing is a facility which makes it possible for the user to share remote I/O devices in the distributed system. This paper describes how to implement three proposed facilities in a Mach-based distributed system with 386 PCs connected through the Ethernet.

This study investigated the differences of sargent jump, muscular isokinetic strength and flexibility depending on resting time and number of sets of static stretching on 13 male participants in their 20s. With 13 persons aged 20 as a subject, it measured the flexibility, muscular isokinet strength and sargent jump after 4 different stretching programs with different number of sets and resting time in order to know the differences between the amount of rest periods depending on the number of sets and the number of sets depending on the amount of rests. There is significant difference in between stretching sets and change of sargent jumps according to the resting time and number of stretching sets. There is a significant difference in the amount of resting time on muscular isokinetic strength, between resting time and sets in isokinetic flexed muscle strength by 60% and change of muscular isokinetic strength according to between resting time and stretching sets. There is a significant difference in between resting time and sets on isokinetic extended muscular strength and between rest time and in-between sets on 180■ angular velocity on isokinetic flexed muscular strength. There is no statistical difference on flexibility according to the number of rest time and sets. The result above showed that increasing the amount of time of stretching and decreasing the amount of rest perios in between will lessen the sargent jump and isokinetic muscular strength.

박상서(Sang Seo Park),김성조(Sung Jo Kim) 한국정보과학회 1995 정보과학회논문지 : 시스템 및 이론 Vol.22 No.9

In order to develop a high performance computer, it is essential to design and implement the monitor which can measure correctly the performance of its operating system The performance monitor should be able to collect performance statistic based on time variation and to measure the time taken to process the specific function of operating system In this paper, we propose a hybrid monitoring mechanism which can be used in measuring the performance of multiprocessor Unix efficiently We describe how to design the monitor based on the proposed mechanism and how to implement its prototype. Our mechanism makes it possible both to collect performance statistic and to measure the time taken to process the function of operating system. Further, it provides a consistent view on the target system of which performance is being measured since the granularity of performance measurement becomes fixed as function. Our monitor also can minimize overhead and perturbation on the target system since it is partitioned into the measuring part and the browsing part, which are located on physically separated machines. 성능이 우수한 시스템 개발을 위해서는 운영 체제 성능을 정확히 측정할 수 있는 모니터의 설계 및 구현이 필수적이다. 성능 모니터는 시간의 변화에 따른 성능 통계 자료를 수집할 수 있어야 하며 운영 체제의 처리 시간을 측정할 수 있어야 한다. 본 논문에서는 다중프로세서 Unix의 성능 측정에 효율적으로 이용될 수 있는 혼합 모니터링 기법을 제시한 뒤, 제안된 기법을 기반으로 설계된 모니터와 원형 구현에 관하여 기술한다. 본 논문에서 제안된 기법은 성능 통계 자료의 수집과 운영 체제의 처리 시간 측정이 모두 가능하다. 뿐만 아니라, 측정 단위가 함수로 고정되어 있어 측정 대상에 대하여 기존의 기법에 비해 일관된 뷰를 제공한다. 또한, 설계된 성능 모니터는 성능을 측정하는 부분과 측정된 성능을 브라우징하는 부분이 물리적으로 서로 다른 기계 상에 분리되어 있어 대상 시스템에 부과되는 오버헤드와 영향을 최소화한다.

The climatology in stratospheric ozone over the Korean Peninsula, presented in previous studies (e.g., Cho et al., 2003; Kim et al., 2005), is updated by using daily and monthly data from satellite and ground-based data through December 2009. In addition, long-term satellite data [Total Ozone Mapping Spectrometer (TOMS), Ozone Monitoring Instrument (OMI), 1979~2009] have been also analyzed in order to deduce the spatial distributions and temporal variations of the global total ozone. The global average of total ozone (1979~2009) is 298 DU which shows a minimum of about 244 DU in equatorial latitudes and increases poleward in both hemispheres to a maximum of about 391 DU in Okhotsk region. The recent period, from-1980s (1979~1982). The long-term trends were estimated by using a multiple linear regression model (e.g., WMO, 1999; Cho et al., 2003) including explanatory variables for the seasonal variation, Quasi-Biennial Oscillation (QBO) and solar cycle over three different time intervals: a whole interval from 1979 to 2009, the former interval from 1979 to 1992, and the later interval from 1993 to 2009 with a turnaround point of deep minimum in 1993 is related to the effect of Mt. Pinatubo eruption. The global trend shows ?0.93% decade?¹ for the whole interval, whereas the former and the later interval trends amount to ?2.59% decade?¹ and +0.95% decade?¹, respectively. Therefore, the long-term total ozone variations indicate that there are positive trends showing a recovery sign of the ozone layer in both North/South hemispheres since around 1993. Annual mean total ozone (1985~2009) is distributed from 298 DU for Jeju (33.52°N) to 352 DU for Unggi (42.32oN) in almost zonally symmetric pattern over the Korean Peninsula, with the latitudinal gradient of 6 DU degree?¹. It is apparent that seasonal variability of total ozone increases from Jeju toward Unggi. The annual mean total ozone for Seoul shows 323 DU, with the maximum of 359 DU in March and the minimum of 291 DU in October. It is found that the day to day variability in total ozone exhibits annual mean of 5.7% in increase and ?5.2% in decrease. The variability as large as 38.4% in increase and 30.3% in decrease has been observed, respectively. The long-term trend analysis (e.g., WMO, 1999) of monthly total ozone data (1985~2009) merged by satellite and ground-based measurements over the Korean Peninsula shows increase of 1.27% decade?¹ to 0.80% decade?¹ from Jeju to Unggi, respectively, showing systematic decrease of the trend magnitude with latitude. This study also presents a new analysis of ozone density and trends in the vertical distribution of ozone for Seoul with data up to the end of 2009. The mean vertical distributions of ozone show that the maximum value of the ozone density is 16.5 DU ㎞?¹ in the middle stratospheric layer between 24 ㎞ and 28 ㎞. About 90.0% and 71.5% of total ozone are found in the troposphere and in the stratosphere between 15 and 33 ㎞, respectively. The trend analysis reconfirms the previous results of significant positive ozone trend, of up to 5% decade?¹, in the troposphere and the lower stratosphere (0~24 ㎞), with negative trend, of up to ?5% decade?¹, in the stratosphere (24~38 ㎞). In addition, the Umkehr data show a positive trend of about 3% decade?¹ in the upper stratosphere (38~48 ㎞).
