우리나라에서 주로 사용되고 있는 흑색 비닐멀칭과 신개발된 적색 비닐멀칭의 표면 반사광 특성을 분석하고 참외와 토마토에 대한 영향을 구명하여 작물생산에 대한 적용 가능성을 검토하였다. 적색 비닐멀칭의 표면에서 반사된 적색광과 초적색광의 일일 누적 강도는 흑색 비닐멀칭보다 2.6배 강했다. 적색광과 초적색광 반사광의 강도는 적색 비닐멀칭의 표면 높이 30 cm에서 가장 강하였다. 일중 태양광 강도가 강한 오후 1시 20분의 흑색 비닐멀칭의 Red/F-Red는 1.14, 적색 비닐멀칭은 0.93, 태양광은 1.16으로 적색 비닐멀칭이 흑색 비닐멀칭보다 초적색광 강도가 높았다. 적색 비닐멀칭의 Red/F-Red는 표면 높이 30 cm에서 가장 낮았으며 표면높이가 높아질수록 초적색광 강도가 감소하여 Red/F-Red는 증가하였다. 적색 비닐멀칭 반사광의 Red/F-Red는 정오부터 오후 4시경까지는 흑색 비닐멀칭보다 낮게 경과하였다. 흑색 비닐멀칭 처리구보다 적색 비닐멀칭 처리구의 참외 과실의 무게가 증가하여 수량이 증가하였고 당도가 높았다. 토마토의 과실 무게와 당도도 적색 비닐멀칭 처리가 흑색 비닐멀칭 처리구보다 높았다. 지중온도는 적색 비닐멀칭 처리가 흑색 비닐멀칭 처리보다 다소 낮은 경향이었다. 따라서 적색 비닐멀칭으로 토양을 피복하면 작물생산에 적색광과 초적색광을 더 많이 이용할 수 있을 것으로 판단된다.

Red tide(harmful algae) in the Korean Coastal Waters has a given a great damage to the fishery every year. However, the aim of our study understands the influence of meteorological factors (air and water temperature, precipitation, sunshine, solar radiation, winds) relating to the mechanism of red tide occurrence and monitors red tide by satellite remote sensing, and analyzes the potential area for red tide occurrence by GIS. The meteorological factors have directly influenced on red tide formation. Thus, We want to predict and apply to red tide formation from statistical analyses on the relationships between red tide formation and meteorological factors. In future, it should be realized the near real time monitoring for red tide by the development of remote sensing technique and the construction of integrated model by the red tide information management system (the data base of red tide - meteorological informations). Finally our purpose is support to the prediction information for the possible red tide occurrence by coastal meteorological information and contribute to reduce the red tide disaster by the prediction technique for red tide.

네트워크 장비를 관리함에 있어서 환경에 따른 RED(Random Early Detection) 매개변수에 대한 설정은 쉽지 않은 일이다. 특히 관리자가 환경의 변화에 따라 일정한 서비스율을 유지하고 싶은 경우의 매개변수 설정은 더욱 쉽지 않은 일이다. 본 논문에서는 출력 큐에 멀티 코어 CPU를 탑재한 라우터를 가정하고 라우터의 출력 큐에, RED의 환경에 따른 매개변수의 최적화에 적합한 것으로 알려진, 인공지능의 유전 알고리즘을 직접적으로 도입하여 스스로 부하에 적응하는 AI RED(Artificial Intelligence RED)를 제안한다. AI RED는 FuRED(Fuzzy-Logic-based RED) 보다 단순하고 세밀하며, 실험을 통하여 AI RED가 찾아낸 RED 매개변수는 표준 RED 매개변수보다 환경에 더욱 잘 적응하는 효율적인 서비스를 제공하여 준다는 것을 확인 할 수 있다. RED 매개변수 관리의 자동화는 네트워크 관리의 측면에서 많은 효율성의 향상을 관리자에게 제공하여 줄 수 있다.

This experiment was conducted over a 3-year period (1990-1992) to evaluate the production and quality of orchardgrass (Potomac)-red clover (Kenland) mixture when orchardgrass + red clover mixture was sown at seed rates of 20+0. 18+2, 16+4, 14+6 and 12+8 kg/ha. Total herbage dry matter, crude protein and digestible organic matter production and organic matter intake were markedly affected by increasing rcd clover seed rate, those increased with increasing red clovcr seed rate due to the cnhancernent of red clover percentage of total herbagc in all 3-year. but significant differences occured between the orchardgrass alone and orchardgrass-red clover mixture with a seed rate of 4,6 and 8 kg/ha red clover (P<0.01). But on the other hand increasing red clover seed rate increased red clover percentage in total herbage, the mean red clover percentage of total herbage at the last cutting ranged from 54 to 65% in first year. 58 to 60% in second year, and 62 to 69% in third year, particularly it was observed that red clover was sown at seed rates of 6 and 8 kg/ha for red clover sown dominated strongly as the cutting times were progressed. Considering the maintenance of good botanical composition balance and the enhancement of production and quality of herbage, the optimized seed rate for orchardgrass-red clover mixtures, 16 kg/ha orchardgrass and 4 kg/ha red clover seems to be considered adequate.

Red quasars have been suspected to be an intermediate population between merger-driven star-forming galaxies and normal quasars. In this scenario, red quasars are expected to have dusty red color coming from the dust extinction by dust and gas in their host galaxy. However, several studies have proposed different explanation of the red color of red quasars, which are i) a moderate viewing angle between type 1 and 2 quasars, ii) an unusual covering factor of dust torus, and iii) an anomalous synchrotron emission with a peak at NIR wavelength. In this study, we investigate the factor leading to the red color of red quasars by using the line luminosity ratios of the hydrogen Balmer to Paschen series of 11 red quasars. We find the Pb/Hb luminosity ratios of the red quasars are significantly higher than those of normal quasars. Moreover, we compare the Pb/Hb luminosity ratios of the red quasars to the theoretically expected line luminosity ratios computed from the CLOUDY code. We find the line luminosity ratios of the red quasars cannot be explained by the theoretical line luminosity ratios with any physical conditions. We conclude that red color of red quasars comes from dust extinction by their host galaxy. This result is consistent with the picture that red quasars are an intermediate population between the merger-driven star-forming galaxies and normal quasars.

Provitamin A carotenoids($\alpha$- $\beta$-carotene lutein capsanthin) cintents in various red pepper and red pepper products were analyzed by HPLC and UV/VIS spectroscopy. The amounts of $\beta$-carotene and capsanthin were at its highest in powdered red pepper and lutein in red pepper leaves. There are little $\alpha$-carotene present in all samples analyzed. So vitamin A activity was calculated only from $\beta$-carotene content. Capsanthin and $\beta$-carotene contents of red pepper were higher than those of green pepper whereas lutein content of red pepper was lower than that of green pepper. whereas lutein content of red pepper was lower than that of green pepper. Vitamin A activity from colorimetric analysis was higher than that from chromatographic method and results were not generally in accordance with the vitamin A data presented in current food composition tables. Vitamin A activities in retinol equivalent(R. E. ) of green pepper red pepper powdered red pepper fermented red pepper paste and red pepper leaves were 70, 570, 1, 340, 140, 980 R. E respectively.

There is increasing interest in the relationships between marine bacteria and red tide organisms. Some bacteria are known to kill red tide organisms, and may be responsible for accelerating the termination of red tides. Thus, certain algicidal bacteria have been proposed for the control of red tides. Meanwhile, many red tide organisms are known to feed on marine bacteria. The roles of marine bacteria and red tide organisms are therefore reversible. In Korean waters, the killing of red tide organisms by algicidal bacteria, and also the feeding of red tide organisms on marine bacteria have been extensively investigated. The findings of such studies may influence the conventional view of red tide dynamics, and also planktonic food webs. Here, we review the species and concentrations of algicidal bacteria that kill red tide organisms in Korean waters, as well as the ingestion rate and grazing impact of red tide organisms on marine bacteria. Furthermore, we offer an insight into the ecological roles of these 2 components in marine planktonic food webs.

This study was carried out to investigate a point of difference between normal and inferior Korean red ginseng (Naeback red ginseng = red ginseng with white part of clear boundary in phloem and/or xylem of ginseng body, saengnaeback red ginseng red ginseng with white part of indistinct boundary). White part with clear or indistinct boundary in center of ginseng body was observed in inferior red ginseng (naeback and saengnaeback red ginseng), and the differences in the internal color intensity was also found with naked eye. In hunter color values of normal and inferior parts of red ginseng in accordance with particle size, L value was increased with a diminishment in particle size, while a and b value were decreased. Absorbance at visible spectrum did not differ from water and 70% ethanol extract from normal and inferior parts of red ginseng, but absorbance in UV spectrum of extract from naeback part showed higher than those of normal and saengnaeback part. In comparison of intrastructure by electron microscope, the horizontal and vertical section of cortex and pith layer from normal part showed the very dense state, but small holes were found in naeback part of red ginseng by naked eye and electron microscope. The specific surface area of normal, naeback and saengnaeback part appeared 3.02, 3.33 and 6.55 ㎡/g, respectively. From above results, we consider saengnaeback red ginseng is red ginseng in the intermediate process which normal red ginseng changes to naeback red ginseng.

The aim of this study was to determine microbiological contamination of fresh-red pepper and packaged-red pepper powder commercially available in South Korea. Thirty-seven fresh-red peppers were collected from 5 farms and 31 packaged-red pepper powders were purchased from retail markets in South Korea. Foodborne pathogens (Escherichia coli, Salmonella spp., Listeria monocytogenes, Staphylococcus aureus and Bacillus cereus), total viable counts, Enterobacteriaceae, coliforms, yeast and mold, and Aspergillus flavus were determined. Detection percentage of contamination of Bacillus cereus in fresh-red pepper was 8.1%, which was lower than the 39% of detection rate in packaged-red pepper powder. The contamination level of Bacillus cereus was 1～3 log CFU/g in packaged-red pepper powder. Escherichia coli was detected in 5.4% of fresh-red pepper samples and was not detected in packaged-red pepper powder. Enterobacteriaceae and coliforms were detected in both of fresh-red pepper and packaged-red pepper powders. Foodborne pathogens, except Bacillus cereus and Escherichia coli, were not detected.
