악성코드 사고 조사에서 가장 중요한 것은 신속하게 악성코드를 탐지하고 수집하는 것이다. 기존의 조사 방법은 시그니쳐 기반의 안티바이러스 소프트웨어를 이용하는 것이다. 시그니쳐 기반의 탐지는 실행파일 패킹, 암호화 등을 통해 쉽게 탐지를 회피할 수 있다. 그렇기 때문에 악성코드 조사에서 패킹을 탐지하는 것도 중요한 일이다. 패킹탐지는 패킹 시그니쳐 기반과 엔트로피 기반의 탐지 방법이 있다. 패킹 시그니쳐기반의 탐지는 새로운 패킹을 탐지하지 못하는 문제가 있다. 그리고 엔트로피 기반의 탐지 방법은 오탐의 문제가 존재한다. 본 논문에서는 진입점 섹션의 엔트로피 통계와 패킹의 필수적인 특징인 'write' 속성을 이용하여 패킹을 탐지하는 기법을 제시한다. 그리고 패킹 PE 파일을 탐지하는 도구를 구현하고 도구의 성능을 평가한다. In malware accident investigation, the most important thing is detection of malicious code. Signature based anti-virus softwares have been used in most of the accident. Malware can easily avoid signature based detection by using packing or encryption method. Because of this, packed file detection is also important. Detection methods can be divided into signature based detection and entropy based detection. Signature based detection can not detect new packing. And entropy based detection has a problem with false positive. We provides detection method using entropy statistics of entry point section and 'write' properties of essential characteristic of packed file. And then, we show packing detection tool and evaluate its performance.

최근에 쓴 장편소설 "사랑"을 통해 나는 사랑을 총체적으로 파악해보고 싶었다. 사랑은 생명력으로 말미암은 것이고, 그것은 내 모든 소설의 궁극적인 화두이자 내 삶의 영원히 풀리지 않는 비밀작업일터다. 사랑이야말로 세상에 존재하는 모든 것들이 살아가는 이유 아닐까.

The purpose of this study was to analyse the effect of air purification by interior plants during photosynthesis. Plants typically obsorb CO2 and release O2 while it was illuminated. The results are as follows : 1.The amount of CO2 absorption was largest, when the light level was highest in a day. 2.The CO2 decreasing rate per unite area was measured with interior plants such as Pachira aquatica, Ficus benjamina, and Dracaena deremensis. The Pachira aquatica showed the highest level of CO2 decreasing rate. 3.The plants that cause high humidity were Dracaena deremensis(91%) and Ficus benjamina(90%). 4.10 species of interior plants such as Ficus benjamina, Dracaena deremensis, Pachira aquatica, Scindapus aureus, Nephrolepis cordifolia, Hedera helix, Cyrtomium falcatum, Farfugium japonicum, Ardisia japonica and Viburnum awabuki - were treated with 0.5% CO2 (0.500%) at the constant light level, 3,000 lux. After six hours, CO2 decreasing-rate of each plant were measured. Viburnum awabuki(15.77,ppm/cm2) showed the highest rate, followed by Farfugium japonicum(15.77,ppm/cm2), Pachira aquatica(4.69,ppm/cm2), Cyrtomium falcatum(4.35,ppm/cm2), Scindapus aureus(2.67,ppm/cm2), Ardisia japonica(2.27,ppm/cm2), Dracaena deremensis(1.38,ppm/ cm2), Nephrolepis cordifolia(1.34,ppm/cm2), Ficus benjamina(0.91,ppm/cm2) and Hedera helix(0.33,ppm/cm2). 5.The CO2 releasing- rate of each plant at the night was also measured. Pachira aquatica(1.54,ppm/cm2) showed the highest rate, followed by Dracaena deremensis(0.75,ppm/cm2), Ficus benjamina(0.26,ppm/cm2), Scindapus aureus(0.42,ppm/cm2), Viburnum awabuki(0.42,ppm/cm2), Cyrtomium falcatum(0.32,ppm/cm2), Hedera helix(0.07,ppm/cm2), Nephrolepis cordifolia(0.06,ppm/cm2), Farfugium japonicum(-0.09,ppm/cm2) and Aridisia japonica(-0.19,ppm/cm2). However, the CO2 releasing rate of interior plant at the night was very low compaed to the CO2 absorption rate of these in the daytime.

<P> The purpose of this study is to demonstrate the positive effects of linear greenspace on the reduction of carbon dioxide (CO₂) which can help improve ecological functions in cities and mitigation of climate change, through quantifying CO₂ uptake and evaportranspiration of some plants. Experiment for CO₂ uptake and evaportranspiration of 7 plants was conducted by measurement of CO₂ exchange rate for 7 month, growing season from May to November 2009. The result was as follows; The CO₂ uptake quantity per ㎠ of Trachelospermum asiaticum was the highest rate at 7.049 × 10⁻⁶ g/㎠ and Hydrangea serrata of the shrubs was 5.369 × 10⁻⁶ g/㎠. The stronger was light of intensity, the higher were CO₂uptake rate of most plants. In quantity of evaportranspiration, Hydrangea serrata was the highest rate at 3.414 × 10⁻⁵ g/㎠ and Euonymus fortunei was 3.650 × 10⁻⁵g/㎠. From this study, it is confirmed that Shrubs and vines composed urban linear greenspace has capacity of absorption CO₂ and effects on improving urban microclimate.</P>
