북한의 금강산댐 건설로 말미암아 일찍이 서산대사(1520-1604년) 가 우리나라 4대명산(동 금강산.서 구월산. 남 지리산. 북 묘향산)의 하나로 꼽은 금강산이 이그러진 모습으로 떠올려짐은 자연을 사랑하는 우리민족에게는 큰 충격이 아닐 수 없다. 본지는 몇가지 자료와 함께 저명한 소설가인 이정수씨 께서 특별기고해주신 금강산탐승의 "수상"을 함께담아 특집으로 묶어보았다.

As mentioned above,we know that the intake of food by people in our country has nearly approched the encouraged amount of nutrition. Based on this fact, many nutritionists conclude that there is no health impediment due to malnutrition, for the nutritive condition of Korean people today is much better than that in the past,and the intake of food and the encouraged amount of nutrition are nearly balanced. Nevertheless, we should not overlook a few points:imperfection of the encouraged amount of nutrition itself;probable imbalance of nutrition due to excessive intake of manufactured food and fast food;the menace to human health due to theaggravation of environmental pollution ; and probable malnutrition due to the destruction of nutrients during the process of cooking because of imperfect education for nutrition. Therefore, in order to maintain the necessary balance of perfact nutrition, we should duly consider the following points : 1. Elimination of environmental pollution. 2. Consumption of food and drink with natural nutrition(without the process of manufacture and cooking) if possible. 3. Reduction of the intake of manufactureed food as much as possible. 4. Consumption of high fiber food and low carbohydrate food if possible. Putting aside various points of view,we can see that the condition of human health is always threatened by various factor even though the dietary life for human health has nearly approached the encouraged amount of nutrition. Therefore, we should empasize the necessity of preventive measure or improvement of supplemental food for human health.
CPU 주파수 속도에 대한 SPEC CPU2000 성능 변화
이정수,김준성,Yi, Jong-Su,Kim, Jun-Seong 대한전자공학회 2005 電子工學會論文誌-CI (Computer and Information) Vol.42 No.5
SPEC CPU2000은 CPU의 성능 측정에 중점을 둔 벤치마크 프로그램으로서 표준화에 대한 노력을 바탕으로 산학계에 널리 사용되고 있으나, 하드웨어 측면에서의 특성 분석은 미비하였다. 본 논문에서는 컴퓨터 시스템의 중요한 구성 요소 중 하나인 CPU 주파수 속도의 변화에 따른 SPEC CPU2000 벤치마크의 성능 변화를 고찰하였다. x86 구조 기반의 단일 프로세서 시스템에서 CPU 주파수 속도를 제외한 다른 구성요소를 일정하게 유지하면서 SPEC CPU2000 벤치마크 프로그램의 성능을 측정함으로써 SPEC CPU2000 벤치마크 프로그램의 특성을 시스템적 측면에서 해석하였다. 실험을 통하여 SPEC CPU2000은 CPU 주파수 속도의 변화에 대하여 유연한 성능분석이 가능하도록 개별 벤치마크 프로그램의 CPU 주파수 의존도가 고르게 분포되어 있음을 알 수 있었으며, SPEC CPU2000에 대한 시스템적 측면의 해석을 제공함으로써 SPEC CPU2000을 사용하는 연구, 개발에 있어서 기반 자료로 사용될 것으로 기대된다. SPEC CPU2000 is an widely used benchmark program, both in industry and in academy, for measuring compute-intensive performance of computer systems with various architectures. However, there has been little effort to investigate its characteristics with respect to hardware components. This paper presents the performance scalability of SPEC CPU2000 benchmark over CPU clock speed. For an Intel x86-based system running at various clock speed, we measure the performance of SPEC CPU2000 benchmark, and analyze the characteristic of SPEC CPU2000 in a system aspect. In the experiment, we found that the overall performance of SPEC CPU2000 increases monotonically and linearly as the CPU clock speed increases and that the scale efficiencies of SPEC CPU2000 component benchmarks are quite evenly distributed.

With rapid advancement in techniques of correcting multiple facial anomalies, surgical planning has become more sophisticated, and knowledge of the exact relationship between various areas of the head and face is now indispensible. The importance of capturing the face in proportions has been emphasized by many surgeons. The neoclassical canons are known to modern plastic surgeons, but their usage in surgical planning has been limited to the role of working guides. They are useful, however, in serving as standards. The authors measured 800 normal young Korean females, ranged from 19 to 26 in age, and 21 beauty contestants in Korea, ranged from 20 to 27 in age. Seven vertical and seven horizontal linear measurements were taken from each subject by one examiner. These measurements of normal face and attractive face are compared with each other, and followed by comparison with neoclassical canons. Attractive face of Korean female comprises shorter lower face, especially from stomion to menton, narrower bigonial distance, and longer midface than normal face. It also has wide palpebral fissure and narrow intercanthal distance. Korean female face comprises shorter and narrower lower face than neoclassical canons. We think that it is valuable to take into consideration of this modern concept of beauty when making a preoperative plan for facial plastic surgery.
중․고등학교 피난 실험을 통한 재실자의 신체치수와 연령 및 성별이 피난속도에 미치는 영향에 관한 연구
이정수,권흥순 대한건축학회지회연합회 2011 대한건축학회연합논문집 Vol.13 No.3
본 연구에서는 성별과 신체치수가 중학교와 고등학교 학생들의 피난속도에 미치는 영향을 검토하였다. 이를 위해서 대전에 있는 중학교와 고등학교를 대상으로 피난실험을 실시하고, 그 결과를 분석하였다. 피난실험에서는 재실자들의 피난속도를 측정하고, 성별에 따른 피난행태 특성을 분석하여 기초 자료를 마련하였다. 피난실험 결과는 복도와 계단에서 측정된 데이터를 바탕으로 분석하였으며, 여자의 경우 중학생 60명과 고등학생 46명이 참가하였고, 남자의 경우 중학생 83명, 고등학생 73명이 실험에 참가하였다. 실험결과, 피난행태적 관점에서 중학생이 고등학생보다 불리한 것으로 나타났으며, 남자보다 여자가 불리한 것으로 나타났다. 또한, Simulex와 같은 피난 시뮬레이션에 적용하는 피난속도 기준값은 국내 중‧고등학교와 차이가 있었다. This study proposed to verify the influences on the speed of refuge from a disaster by the sex and body size in a junior high school & high school. We executed the evacuation experiments in a junior high school & high school in Daejeon Metropolitan City and analyzed the behavior patterns and evacuation speed of evacuee. The results of this study are as follows ; First, we found the evacuation speeds of evacuee are different the velocity of Simulex simulation program. It is necessary to reflect the body types and evacuation behavior characteristics of Koreans in simulation. Second, the body size doesn't have any good relations with the evacuation speed of evacuee in junior high school & high school students, but the physical and psychological conditions in aging affects on the evacuation behaviors. Third, the congested condition of stairway is more critically affects the speed of following evacuee in a middle school & high school, and evacuation condition is unfavorable for women and middle school students.
