9-$\beta$-D-Arabinofuranosyladenine-5'-methoxyacetate (ara-A-MA) 및 1-$\beta$-D-Arabinofuranosylcytosine-5'-methoxyacetate (ara-C-MA)를 합성하였다. 이들 물질의 항암작용을 검토한 바, sarcoma 180 암세포를 이식한 mice중 생리식염수만 공급 받은 negative 대조군은 생존일수가 $16.3{\pm}4.1$일이었고, positive 대조군인 ara-C(13.9 mg/kg/mouse)를 투여 받은 실험군은 생존일수가 $22.0{\pm}2.5$ 일이었다. ara-A-MA를 투여 받은 시험군은 $20.8{\pm}2.9$일(19.4 mg/kg/mouse) 이었고, ara-C-MA를 투여 받은 실험군은 $23.1{\pm}3.3$일(18.0 mg/kg/mouse) 및 $20.1{\pm}2.2$일(1.8 mg/kg/mouse)의 생존일수를 각각 나타내었다. 한편 이들 합성 화합물은 DNA 합성을 억제하는 작용을 나타내었는데, ara-A-MA는 Fischers media에 배양한 sarcoma 180 암세포의 DNA 생합성을 $10^{-3}\;M$ 농도에는 57% 그리고 $10^{-4}\;M$에서 50%를 억제하고, ara-C-MA는 94% 및 80%를 각각의 농도에서 억제시켰다. 이들 결과는 ara-A-MA 및 ara-C-MA가 ara-A 및 ara-C의 prodrug으로서 역할을 할 수 있는 가능성을 시사한다. 9-$\beta$-D-Arabinofuranosyladenine-5'-methoxyacetate (ara-A-MA) and 1-$\beta$-D-Arabinofuranosylcytosine-5'-methoxyacetate (ara-C-MA) were synthesized. Their antitumor activities were evaluated against sarcoma 180 tumor cells inoculated in mice. When administered intra peritoneally once daily for 6 days, average life-spans for those which received ara-A-MA, ara-C-MA, ara-C and saline (0.9%) were; $20.8{\pm}2.9$(19.4 mg/kg/mouse) and $19.1{\pm}2.5$(1.9 mg/kg/mouse) days; $23.1{\pm}3.3$(18.0 mg/kg/mouse) and $20.1{\pm}2.2$(1.8 mg/kg/mouse) days; $22.0{\pm}2.5$(13.9 mg/kg/mouse) days; and $16.3{\pm}4.1$ days, respectively. This survival study indicates that ara-A-MA and ara-C-MA exhibit antitumor activities as much potent as their parent compounds of ara-C. DNA biosynthesis in Sarcoma 180 cells in vitro were also inhibited by ara-A-MA. At the concentrations of $10^{-3}$ and $10^{-4}\;M$, ara-A-MA and ara-C-MA showed 57 and 50%, 94 and 80% inhibitions of DNA synthesis in comparison with that of negative control group, respectively.

Phenylurea, phenylthiourea, benzylcarbamate and toluenesulfonate of L-alanyl-L-proline(comp. $3{\sim}6$) were synthesized and their effects against angiotensin-converting enzyme (ACE) were tested. Comp. 3 showed only mild inhibitory activities against ACE while comp. $4{\sim}6$ were inert indicating that those functional groups were not suitable for interactions with ACE. Ortho-hydroxy- or ortho-carboxy-benzamide of proline (comp. 7) and phenylalanine (comp. 8 and 9) were also tested. Of the benzamides, ortho-hydroxy function was unsuitable to exert inhibitory activities against ACE. Ortho-carboxy group of 9 seemed to have mild interactions with active site of ACE possibly because of the shorter distance between the amide and ortho-carboxyl group of the compound than the corresponding two active sites of the enzyme.

디지털 기법에 의한 환경색채 분석 -Doxel 기법에 의한 마산자유무역지역 색채조사를 중심으로

이희주 ( Hee Joo Lee ) 한국기초조형학회 2012 기초조형학연구 Vol.13 No.4

환경색채계획의 가장 첫 번째 단계는 색채계획을 하고자 하는 대상에 대한 정확한 측색을 하는 것이다. 그 것은 대상물이 가지고 있는 현재의 색채를 정확히 파악하는 것이야 말로 앞으로의 색채를 제안 할 수 있는 근거가 되기 때문이다. 마산자유무역지역은 1970년부터약 40년의 역사를 가진 수출의 전초기지로써 한국과 마산의 경제적 성장을 이루어 낸 곳이다. 그러나, 국내외기업의 공장이 주변 도시의 새롭고 깨끗한 공단으로 이전 해 가면서 마산자유무역지역은 활기찼던 예전의 면모를 점점 잃어버리고 있는 실정이다. 마산자유무역지역에 환경색채디자인 개념을 도입하여 공장의 차갑고 어두운 이미지에서 아름다운 경관과 아이덴티티가 있는 소프트한 이미지로 변화하는 것는 현재 마산자유무역지역이 당면하고 있는 문제를 해결 할 수 있는 디자인적인 과제 중에서 하나일 것이다. 본 연구에서는 마산자유무역지역의 외벽과 지붕을 중심으로 1,2,3 공구에 대한 측색작업인 색채조사를 실시하였다. 그 프로세스는 다음과 같다, 1) 조사대상의 사진촬영 2) “Dot" 에 의한 필요색 추출 3) 조사대상의 색군추출 4) 색의 분류 및 먼셀 색표기 5) 컬러팔레트 작성 6) 먼셀공간배치를 통한 분석. 이와 같은 과정을 거친 색채조사의 결과는 1.2.3 공구의 외벽 기조색은 전체적으로 통일성 없이 원색위주로 분포되어 있었고 명도는 7~10에 집중되어 있었다. 채도는1~11 로 전체적으로 고채도가 나타났다. 지붕과 굴뚝색은 한색인 B/BP에 색상이 집중되어 있었고 명도는 2~6사이에 분포 되어 있었다. 채도는 4~7로 2006년에 세워진 3공구를 제외하고 고채도로 나타났다. The first step of environment-color planning is measuring colors of a subject for color planning. The reason is that examining the current colors of a subject becomes a foundation to suggest future colors. Masan FTZ made economic growth of Korea and Masan as an advance base with 40-year export history from 1970. However, as domestic and foreign company factories moved to new and clean industrial complex, Masan FTZ is losing its active aspect. As one of the most top-priority keywords, Masan FTZ should be transformed into a soft image with beautiful landscape and identity from a dark and cold image of a factory by adopting environment-color design. This study conducted a coloring research that is color-measuring about 1,2,3 Zones focusing on an outer wall and a roof of Masan FTZ. The following process is as shown below. 1) Photo shooting of research subjects 2) extract necessary colors by “Dot" 3) extract color groups of research subjects 4) color classification and Munsell color mark 5) write color pallet 6) analyze through Munsell space arrangement. The result of color research shows that the outer wall base color of 1,2,3 Zones is evenly spread covering wide range, and brightness was centered at 7~10. Chroma was below 1~11. This is because the color fades due to deterioration. The roof and the chimney mainly had a cold color B/BP, and brightness was spread from 2 to 6. A high chroma was found in those zones except for 3 Zone built in 2006.

CIM 기반의 Distribution Automation System에 관한 연구

이희주(Hee-Joo Lee),서정일(Jeong-Il Seo),한주현(Ju-Hyun Han) 대한전기학회 2011 전기학회논문지 Vol.60 No.5

Distribution systems for operating the various systems should be operated organically. Distribution systems for organic operations extend the functionality of the system and system integration for the extension is doing. However, in systems integration for each unique non-standard definition of linkage and exchange systems are used. Non-standard definition of a unique linkage and exchange systems in the maintenance and expansion will result in many negative results. To solve these problems, the system and the exchange of information about the links between systems should define standards. IEC (International Electrotechnical Commission) power to solve these problems in the field of the Common Information Model (Common Information Model, CIM) standard (IEC61970, IEC61968) is defined as the transmission and distribution system integration and standardization for the exchange of information.. In this paper, standardized system for building CIM-based distribution automation system should describe the process of building. In addition, the process of establishing a common information model needed (CIM) defined and associated services for a defined set of models is proposed in the standardization process.
