이 연구는 한국 영화시장에서의 집중화 현상을 고찰하기 위해 스크린 규모와 흥행, 그리고 국적을 중심으로 이를 분석했다. 분석대상은 2005년부터 2019년까지 15년 동안의 연도별 흥행 100위권 영화로, 총 1,500편이다. 분석결과 스크린수는 매년 꾸준히 증가하는 추세였고, 스크린 집중화는 높은 수준으로 나타났다. 흥행 100위 기준 스크린 집중도는 2005년의 12%에서 30% 이상으로 상승했으며, 흥행 10위 기준에서는 2005년 21%에서 큰 상승폭을 보이며 2014년 이후 매년 50% 이상을 차지했다. 개봉 스크린 규모가 증가하면서 멀티플렉스는 흥행유인력이 높은 영화에 보다 많은 스크린을 할당했다. 오랫동안 스크린 독과점에 대한 비판이 있어왔지만 멀티플렉스는 2011년과 2012년 이후 이를 더 심화시키면서 한 편의 영화가 전체 스크린의 60% 이상을 차지하고 개봉되는 상황을 발생시키고 있다. 멀티플렉스의 이런 방식은 흥행 100위권 영화의 시장 점유율을 95%까지 상승하게 하고 있다. 또한 멀티플렉스는 한국영화보다 할리우드 영화에 보다 더 많은 스크린을 할당하는 경향을 보여주었다. 흥행성과가 높은 100위권을 대상으로 한 분석에서 영화 국적은 한국과 미국으로 집중된 것으로 나타났다. 이를 제외한 18개 국가의 경우 공급 측면에서 9.3%만 차지했다. 영화의 국적별 소비를 살펴보면, 두 국가로의 집중화 현상은 더 강하게 나타났다. 공급 차원에서 90.7%를 차지하고 있지만 소비 측면에서 96.6%를 차지했다. 공급에서의 집중화 현상은 소비에서의 집중화 현상과 정적인 상관관계를 보여주었고, 소비 측면에서의 집중화가 공급 측면보다 조금 더 높게 나타났다. 한국 영화시장은 스크린의 증가가 공급과 소비의 집중화를 심화한 사례로 드러났다.

This study suggests that the application of split screen as visual media can attain the effect of diversity through providing rich information and accepting diverse contents as gorgeous aesthetics. Single images are analyzed as appropriate to a demanded concentration genre such as news and dramas, entertainment. In contrast, images with natural images and ads images those are more appropriate and analyzed as the genre of the split-screen which is highly efficiency to the contents and also highly efficiency to the spatial diversification. In introducing various genres of digital contents into split screen, the synergy of contents is induced by placement in consideration of the characteristics of split screen position. In order to increase the concentration of the split-screen image, using the left area and right area above it, can increase the effectiveness of the content.

Moiré patterns emerge due to the interference between the non-emission area of the LED screen and the grid line in an image sensor of a video recording device when taking a video in the presence of the LED screen. To reduce the moiré intensity, we have fabricated an anti-moiré filter using hollow glass microspheres (HGMs) by slot-die coating. The LED screen has a large non-emission area because of a large pitch (distance between LED chips), causing more severe moiré phenomenon, compared with a display panel having a very narrow black matrix (BM). It is shown that HGMs diffuse light in such a way that the periodicity of the screen is broken and thus the moiré intensity weakens. To quantitatively analyze its moiré suppression capability, we have calculated the spatial frequencies of the moiré fringes using fast Fourier transform. It is addressed that the moiré phenomenon is suppressed and thus the amplitude of each discrete spatial frequency term is reduced as the HGM concentration is increased. Using the filter with the HGM concentration of 9 wt%, the moiré fringes appeared depending sensitively on the distance between the LED screen and the camera are almost completely removed and the visibility of a nature image is enhanced at a sacrifice of luminance.

The purposes of this study were to investigate characteristic changes on nonwoven fabric by the charcoal printing. It separate grind charcoal as two different size of particles 45-52${\mu}{\textrm}{m}$ and 53-65${\mu}{\textrm}{m}$ for hand screen printing on three kind of nonwoven fabrics. To examine the effect of charcoal printing on nonwoven fabric were to obselve surface changes by a scanning electron microscope, dyeability by using spectrophotometer, moisture regain by oven method, air permeability, anion property, deodoriration and antibacterial activity. The results were as follows： When charcoal powder concentration increased from 3 to 9％, K/S value also increased from 3.06 to 8.55. When charcoal concentration increased, moisture regain also increased. In same concentration, moisture regain occurred higher as particle of small size. Air permeability decreased when the charcoal printing concentration increased. Anion occurrence appeared 140-160ion/cc from three different kinds of nonwoven fabrics in 3％ and 9％ charcoal concentration. Therefore, occurred anion ineffectively. In concentration of 3％, rate of deodorization measured as 89％, 83％ and 87％, and 9％ concentration caused 96％, 86％ and 93％ of high deodorization. Antibacterial activity examination in nonfinished nonwoven fabric resulted range of 60％, however, 3％ and 9％ concentration finished nonwoven fabric resulted 99.9％ of excellent antibacterial activity.

Smartphone is integrated into the daily lives of all types of people not even young generation. A touch screen display is a primary input device of a smart phone, a tablet computer, etc. While there are many tough technologies in existence, resistive and capacitive are dominant and currently lead the touch screen panel industry. And a capacitive touch screen panel widely used in smart phones is coated with a material that stores electrical charges. In this study, we tried to manufacture gloves produced with electro-conducting leather as a tool to operate a touch panel screen. Therefore, electrically conductive materials, Polyaniline(PANI), Poly(3,4-ethylenedioxythiophene) (PEDOT), and Carbon nanotubes (CNT) were applied to the surface of leather to be used as a touching operator for capacitive touch screen panel. The leather samples were treated by simple painting method; firstly, they were painted with aqueous solution containing each of the electrically conductive materials and then dried. This cycle was repeated three times. Consequently, the treated leather samples showed electrical conductivity and reasonable working performance to the capacitive touch screen. And, PANI showed the best performance and highest electrical conductivity, and then PEDOT and, CNT in decreasing order. This is because the solubilities of PANI and PEDOT show higher than dispersibility of CNT. Thus, the concentration of conducting polymers was greater than that of CNT in the treating solutions.

This research investigated the screen printing method for natural indigo dye on cotton fabric. We examined four types of thickening agents (arabic gum, guar gum, indalca, and CMC) based on their ability to retard the oxidation of natural indigo print paste while the paste remained on the screen frame. The results indicated that the retardation of arabic gum towards oxidation was the greatest among the four types of thickening agents. The highest K/S value of the printed cotton was observed with a dye concentration of 50g/L fermented indigo powder. The best printing results were obtained when the duration of dye efficiency was tested for the 10 minutes of the dye paste remaining on the screen with a thickening agent concentration of 26.56% that represented 530 cps viscosity. The test of colorfastness to washing and rubbing of the printed cotton resulted in grade 5, and the colorfastness to sunlight resulted in grade 4. Chinese traditional Naminwhapo printing was reproduced on cotton fabric using the natural indigo printing method derived from this study.

In this study, sixty chemicals including 47 pesticides were screened for estrogenic activity using E-screen assay. MCF-7 cell, used in E-screen assay, is known to be proliferated by addition of estrogenic chemicals. Eight of the measured pesticides showed estrogenic activity at the concentration range of 100-10,000nM. Their relative proliferative effect (RPE) and the relative proliferative potency (RPP) were 20-65% and 0.01-1.0%, respectively, when compared with 1.0nM of $\beta-Estradiol-17-acetate(E_{2}).$ DDVP and diazinone showed most strong estrogenic potency(RPP; 1.0%) and effect(RPE; 65%) of the eight pesticides. These results are in agreement with estrogenic activity of bisphenol A is known as a positive endocrine disrupter. Also, in this study, paraquat, DDVP, 4-chloro-3-methylphenol, 2,4,6-trichlorophenol and diazinon of the measured pesticides are estimated to estrogenic chemical.
