클로즈 업 숏은 영화의 서사구조와 밀접한 관련이 있다. 등장인물의 얼굴을 확대하여 보여줌으로써 표정의 변화를 섬세하게 표현할 수 있다. 이를 통해 관객에게 등장인물의 감정이나 심리상태를 세밀하게 묘사해 줄 수 있다. 따라서 영화에서 클로즈 업 숏을 검출하고 분포도를 파악하는 것은 영화의 서사구조를 분석하는데 있어 중요한 데이터로 활용될 수 있다. 또한 영화의 정보 검색에 활용될 수도 있다. 본 논문에서는 얼굴 검출 기술을 활용하여 클로즈 업 숏을 자동으로 검출하여 영화의 클로즈 업숏 분포도를 계산하는 방법을 제안한다. 또한 제안한 방법을 시스템으로 개발하여 서사구조와 클로즈업 숏 간의 관계를 분석한다. 10개의 영화에 대한 실험을 통해 클로즈 업 숏이 영화의 전반부보다 후반부로 갈수록 많이 사용되는 것을 확인하였다.

Effect of chlorogenic acid, one of polyphenolic compounds, on the concentrations of lipid in serum and hepatic lipid, serum glucose, and urinary protein in Sprague Dawley rats for 14 days was investigated. The concentration of serum total cholesterol was increased in the cholesterol group compared with the control group, while it was decreased in the cholesterol+chlorogenic acid group. The concentrations of hepatic triacylglycerol and cholesterol were increased in the cholesterol group, while these were not altered by the supplementation of chlorogenic acid. The concentrations of serum glucose and urinary protein were higher in the cholesterol+chlorogenic acid group than the control and the cholesterol groups. These results suggest that chlorogenic acid exerts a hypocholesterolemic effect in the rats fed cholesterol.

Synthesis of unsymmetrical trisannelated benzenes such as 2,3,4,5,6,7,8,9,10,11-decahydro-1H-cyclopenta[l]phenanthrene (1c) and 1,2,3,4,5,6,7,8,9,10-decahydrobenz[e]-as-indacene (1d) is described. The synthetic approach involves efficient condensation of pre-formed enones such as bicyclohexyliden-2-one (3), bicyclohexyl-1-en-2-one (4) and bicyclopentyliden-2-one (5) in the presence of cyclopentanone and cyclohexanone using anhydrous $CuCl_2$ as a catalyst.

Perchlorate ($ClO_4^-$) is a contaminant found in surface water and soil/ground water. Microbial removal of perchlorate is the method of choice since microorganisms can reduce perchlorate into harmless end-products. Such microorganisms require an electron donor to reduce perchlorate. Conventional perchlorate-removal techniques employ heterotrophic perchlorate-reducing bacteria that use organic compounds as electron donors to reduce perchlorate. Since continuous removal of perchlorate requires a continuous supply of organic compounds, heterotrophic perchlorate removal is an expensive process. Feasibility of autotrophic perchlorate-removal using elemental sulfur granules and activated sludge was examined in this study. Granular sulfur is relatively inexpensive and activated sludge is easily available from wastewater treatment plants. Batch tests showed that activated sludge microorganisms could successfully degrade perchlorate in the presence of granular sulfur as an electron donor. Perchlorate biodegradation was confirmed by molar yield of $Cl^-$ as the perchlorate was degraded. Scanning electron microscope revealed that rod-shaped microorganisms on the surface of sulfur particles were used for the autotrophic perchlorate-removal, suggesting that sulfur particles could serve as supporting media for the formation of biofilm as well. DGGE analyses revealed that microbial profile of the inoculum (activated sludge) was different from that of the biofilm sample obtained from enrichment culture that used sulfur particles for $ClO_4^-$-degradation.

Perchlorate is an anionic pollutant that is very soluble and stable in water. It has been detected not only in soil/ground water but also in surface water, drinking water, food, fish, and crops. Perchlorate inhibits iodine uptake by the thyroid gland and reduces production of thyroid hormones that are primarily responsible for regulation of metabolism. Although various technologies have been developed to remove perchlorate from the environment, biodegradation is the method of choice since it is economical and environmentally friendly. However there is limited information on perchlorate biodegradation in salt environment such as salt water. Therefore this paper reviews biodegradation of perchlorate in salt water and related microorganisms. Most biodegradation research has employed heterotrophic perchlorate removal using organic compounds such as acetate as electron donors. Biodegradation research has focused on perchlorate removal from spent brine generated by ion exchange technology that is primarily employed to clean up perchlorate-contaminated ground water. Continuous removal of perchlorate at up to 10% NaCl was shown when bioreactors were inoculated with enriched salt-tolerant perchlorate-reducing bacteria. However the reactors did not show long-term stable removal of perchlorate. Microorganisms belonging to ${\beta}$- and ${\gamma}$-Proteobacteria were dominant in bioreactors used to remove perchlorate from salt water. This review will help our understanding of perchlorate removal from salt water to develop a decent biotechnology for the process.

The effect of chlorella addition on quality and shelf-life of soybean curd was investigated. The yield of chlorella soybean curd was the highest with 1.0% (w/w) chlorella addition. Hardness, gumminess, and chewiness of chlorella soybean curd increased, whereas Hunters color values decreased in proportion to amount of chlorella added. No significant differences were observed between the sensory properties of chlorella and ordinary soybean curds. Microbial counts of soybean curd stored in sterilized distilled water as tofu-immersion solution increased, whereas pH decreased during storage at $15^{\circ}C$. After 5 days storage, microbial counts of the soybean curds containing 0.5 and 1.O% chlorella were lower than that of the ordinary soybean curd. These results imply that chlorella is a useful additive to suppress the proliferation of aerobic microorganism in soybean curd at the optimal concentration of chlorella around 1%.

There has been an increased awareness of the need to confirm the chloroform exposure associated with using chlorinated household water. Ten of a 30-minute tub bath were normally taken by two volunteers in a bathroom of an apartment. Chloroform concentrations were measured in bathing water and bathroom air, and exhaled breath of the subjects prior to and after bathing. Bathing using chlorinated tap water resulted in a chloroform exposure and caused a body burden. Based on the difference of chloroform concentrations between breath samples collected prior to and after bathing, the chloroform body burden from a 30-minute bath was estimated to be about 8 to 26 folds higher than that prior to the bath. The mean water and bathroom air chloroform concentrations measured to evaluate the body burden were $9.4\mu\textrm{g}/l$ and TEX>$14.9\mu\textrm{g}/m^3$, respectively. The chloroform level of the bathroom air was 각 to 130 times higher than that of the living-room air. The relationship between the bathroom air and the corresponding breath chloroform concentrations were significant with p=0.03 and $R^2=0.47$.

When the water curtain system is employed to keep the liquefied gas in the underground storage cavern, clogging is observed in borehole. Since this phenomenon causes serious difficulties in managing LPG storage cavern, it needs to detect the degree of clogging accurately under various circumstances. Thus, in this study the active factors of clogging, that is, groundwater head, injection water flowrate, and seepage water flowrate, were investigated experimentally using a physical model. Experimental results show that groundwater head around storage cavern increases as cavern Pressure increases, while it decreases as clogging becomes severe. The pressure in storage cavern is required to reduce up to atmospheric pressure in order to detect and identify the degree of clogging more accurately. The decrease of uroundwater head due to clogging slows down as the pressure in borehole increases. As amounts of suspended matters in injected water increase, both injection water flowrate and seepage water flowrate decrease linearly with time, and the flowrate of injection water drops rapidly compared with seepage water flowrate.
