이 글은 물질의 본질로 규정한 아리스토텔레스의 색채론과 디지털이미지의 비물질적 특성으로서의 검정을 전제로, <신과 함께>의 서사를 주도하는 인물과 이미지를 구성하는 공간에 채워진 검정의 의미를 분석한다. 할리우드영화에서 검정은 악의 근원이며 공포이다. 검정에 관한 예외적이고 특별한 특성을 성찰하는 철학, 회화, 문학에서의 비유와 달리, 대중영화에서 검정은 가장 보편적인 의미를 표현한다. 삶과 죽음의 경계를 오가는 <신과 함께>에서 검정은 저승의 공간과 차사라는 인물을 구성한다. 한국영화에서 검정은 상상의 공간을 상징화하는 유용한 색이다. 이 글은 한국영화 <신과 함께>에 사용된 검정을 통해 동서양 색채문화의 차이를 살펴보고, 사회문화적 맥락에 따라 상호작용하는 의미를 분석한다.

Twelve Camellia sinensis populations were studied to investigate the biomass distribution related to stand structure. With increasing mean age of the population, mean root collar diameter increased, while mean height, density and root collar area had no correlation with the age. The result of dimension analysis after cutting the sample trees showed that dry weights of stems +branches and root were exponentially increased and dry weights of current leaves and twigs were linearly increased with increasing root collar diameter. However, the dry weight of older leaves was not related to the root collar diameter. The range of total biomass was 1,162~11,474kg/ha and the range of current leaf biomass was 165~1,341kg/ha. The range of T/R ratio was 1.5~2.8. The biomass of stems+branches and root were significantly correlated with the root collar area of the population and were not significantly correlated with the mean age, mean root collar diameter and density of the population. The biomass of current leaves and twigs were significantly correlated with the root collar area and density of the population.

화학관련분야의 공정안전에 관하여 오랜 역사를 가진 AIChE는 관련산업분야의 안전규정을 예방적인 측면과 사고원인을 규명하기 위한 측면에서 근원적인 자료를 제시하였고 1955년 AIChE에 의해 설립된 CCPS(center for chemical process safety)는 이에 관한 기술적인 면에 더욱 발달된 정보를 제공하게 되었다. 이런 정보들 가운데 사업장의 위험물질이 지니고 있는 위험성을 어떻게 평가할 것인가에 관하여 CPQRA(chemical process quantitative risk analysis)방법이 제시되어 있다. 1) CPQRA는 양적인 의미에서 위험성의 정의, 분석, 평가, 통제 및 관리방법 등에 대비해 잠재적인 방법을 제시한 것이다.

This study was carried out to investigate the effect of light intensity on the growth and biomass production of Pinus thunbergii seedlings. The experiment was performed under five different light intensities such as 100, 50, 30, 10, and 25 of the natural full sun light intensity for 2 year in the field condition. The seedling showed the highest height and root collar diameter growth under natural full sun light. The height growth of the seedling under 50% of light intensity showed 96.4% of the control seedling in the first year, and 88.9% in the second year, and the root collar diameter growth showed 94.1% in the first year 77.6% in the second year. Height and root collar diameter growth was markedly reduced below 30% of relative light intensity, and the reduction rate of root collar diameter growth was higher than that of height growth. All the tested seedlings died under 2% of relative light intensity in the second year. Biomass production was also reduced by decreasing of relative light intensity, the reduction rate of root biomass production in both first and second years was higher than that of leaf or shoot biomass production. The lowest reduction was observed at the shoot in the first year, and at the leaves in the second year The highest T/R ratio was recorded by 3.55 in the seedling under 50% of relative light intesity in the first year, and by 4.88 under 10% of relative light intensity in the second year.

이제 우리나라도 에너지 다소비형 산업구조를 에너지 절약형으로 조속히 전화시켜야 한다고 보면서 에너지 효율 향상을 위한 연구개발에의 집중투자를 통한 근원적 환경보전 노력을 활성화 시켜야 한다고 본다. 아마도 오늘날의 우리에게 중요한것은 생태계에 미치게 될 충격의 최소화, 자원(물질과 에너지)의 보전 극대화, 인구증가의 억제 및 이를 향유할 수 있게 하는 사회시스템의 확립 등이 곧 인류가 살아남기 위한 청사진의 주요골격이 될 것으로 보며, ESSD적 개념을 현실화하는 활력소가 될것이라고 본다.

화학공장의 각종 공정설비의 규모가 커지고 복잡화됨은 물론 사용되는 화학물질의 다양화 및 사용량의 증대로 화재·폭발의 위험성이 잠재하고 있다. 이러한 중대 산업사고를 예방하기 위해 세계 각 국에서는 화재폭발에 관한 연구가 수행되고 있다. 본고에서는 최근 일본에서 화재폭발에 관한 연구동향을 일본 소방청 소방연구소와 산업안전연구소의 연구과제를 중심으로 소개하고자 한다.(중략)

In order to find out whether myoblast cells release into the culture medium any substances that induce or promote the fusion of myoblasts, chick embryonic myoblasts were cultured and the cultured medium (muscle-conditioned medium, MCM) was collected. The MCM was then added to the newly cultured myoblasts to examine if it has fusion-promoting activity. The MCM was also analyzed for its protein content before and after its addition to the second culture. The MCM apparently showed fusion-promoting activity when applied to unfused young myoblasts, suggesting that it contained substances that promote the fusion and that had been released from cells fo the previous culture. Analysis of proteins in the myoblasts and in the MCM suggested that the released protein was absorbed by or tightly bound to myoblasts of the second culture. One of the released proteins of about 175 kilodalton was degraded to a polypeptide of approximately 145 kilodalton, which appeared to act upon the membrane proteins of unfused myoblasts so as to stimulate their membrane to fuse with neighboring cells.

In order to elucidate the effect of neurotransmitter on the differention of myoblasts in vitro, dopamine was administered to the myoblasts at varying stages of myogenesis, and the fusion index, the rate of creatine kinase (CK) synthesis, and the sensitivity to dopamine were determined. When dopamine $(3 \\times 10^{-5} M)$ was administered at 34 hr after myoblast seeding, a significant decrease in the fusion index as well as CK synthesis was observed, indicating a good correlation exists between these two parameters. In other experiment, dopamine was administered at varying stages of myogenesis and the inhibitory effect of dopamine as scored by fusion index at 96 hr was found to be cyclic in nature. This finding raised a possibility that arrangement of dopamine receptors occurs according to the cell cycle stages in myogenesis.

분자생물학의 급진적 발전은 현대 계통분류학에 큰 변혁을 가져왔다. 특히 유전의 근원물질인 DNA나 RNA를 분리.조작.분석하는 기술의 발전으로 이를 이용만 계통수 제작은 계통생물학의 중요한 실험방법으로 자리잡고 있다. 그 중 염기서열 비교 방법은 현재 유전자 계통수 제작에 가장 널리 이용되는 방법이다. 하지만 이러만 계통수는 각 객체간의 거리만을 표현하고, 객체군간의 차이는 설명하기 힘들다. 본 연구에서는 염기서열의 상대적인 특징(유사도)을 대신하는 염기서열의 총량과 염기 함량 등을 이용해 새로이 분류 기법 중 결정트리 방법에 적응하고, 종 분류의 유전적 모델을 설계한다. 또한 결정트리의 클래스인 종은 상위 클래스들을 포함하고 있어, 본 논문에서는 기존의 결정트리 분류자를 수정한 단계적 결정트기 분류자를 제안한다.

To provide the basic data essential for developing varieties of broad-leaved tree, the study investigated the utmost growth requirement for the growth characteristic and biomass production in accordance with planting density of Styrax obassia. The planting density of seedling can be a significant factor in contributing growth of seedling for tree growing in general. While growth of tree according to $1m^2$ planting density of Styrax obassia showed an excellent growth in tree height and the root collar diameter from $49no./m^2$, those low planting density showed decreased tendency with tree height growth while increasing the root collar diameter growth. As similar to the growth characteristic, the biomass production showed significant and statistic difference in $49no./m^2$, showing high volume of biomass production which is $3.12{\pm}0.80g$ compare to other processing section and high figure with T/R ratio which is 1.59. The special trait of photosynthetic also showed relatively high photosynthetic rate in $49no./m^2\;and\;64no./m^2$ of Styrax obassia and as the density increase, photosynthetic efficiency decreased. The plant showed stable and physiological planting pattern, displaying the best photosynthetic rate, which was the final metabolism through reserving proper space in the growth and development environment condition. This obstacle of required space essential for growth substantially deteriorated planting and ultimately, it demonstrated lower tendency of photosynthetic rate, which is the highest level of metabolism.
