This research used High Performance Liquid Chromatography(HPLC) to analyze and compare the content and the pattern of chlorophyll to find the difference in quality, water temperature, and the stirring time between the three different types of Korean and Japanese powder green tea, which were currently on the market. Chlorophyll contents of Japanese-made medium quality tea (S5; 8.34㎎/g), and low quality tea (S6; 8.23㎎/g) were relatively high, and that of Korean-made medium quality tea (S2 ; 4.87㎎/g) was lower. The water temperature of 85℃ and 95℃ were high except in Korean-made medium and low quality powder green tea (S2 and S3). Japanese-made powder tea required 60 seconds of stirring time and Korean-made tea required 15 seconds, but 30 seconds seem to be the ideal stirring time for both of them. Chlorophyll a, b, pheophytin a, b, and pheophorbide were confirmed from the chlorophyll pattern. There were 1.5~2 times more of chlorophyll a in Japanese-made one compared to that of Korean-made one; also 1.5 ~2 times more of pheophytin a in Korean-made one than Japanese-made one. It might be concluded that Japanese-made powder green tea was higher in quality.

Purpose: To find out the effects that different tomographic angles have on the osteophytic lesion detectability of condyle head by comparison the individualized lateral tomographic image with the various tomographic angled images using SCANORA . Materials & Methods: This study is performed to simulate osteophytic lesions by a series of dentin chips placed at six locations on condyle head. The control angle is 15°and from this angle, tomographic angle were varied with -10°, +10°+20°. All the images with each sized dentin chip were scored by three dental radiologists with the use of confidence levels for presence or absence of the lesion, each examiner viewed one of the images twice. A rating scale from 0 to 2 (0, lesion definitely not present; 1, uncertain if lesion is present; 2, lesion definitely present). Responses were assessed by Tukey's multiple comparison method and kappa value. Results: 1. The lesion size of 0.3mm could not be detected in all the tomographic angles. As the size of the lesion increased the average value of lesion detectability also increased. 2. In the lesion sizes of 0.7mm there was statistically significant difference between the 15°control angle and the altered tomographic angles (p<0.05). In 1.0mm lesion there was no significant difference in the ±10°altered angles (p<0.05), but there was significant difference in the altered angle(p<0.05). In the lesion sizes of 0.3mm and 2.0mm there was no significant difference between the 15°control angle and all the altered angle(p>0.05). 3. In the anteromedial, anterosuperior, anterolateral area there was no significant difference between the 15°control angle and the ±10°altered angle(p>0.05), but in the comparison with the +20°alterd angle there was significant difference(p>0.05). Conclusion: When imaging the lateral tomography of the temporomandibular joint used by SCANORA, it can be considered that in the osteophytic lesion size of 2mm and above, the tomographic angle difference within +20°to the horizontal angle of the condyle, has little effect on the lesion detectability. And in the lesion size of 1mm, the altered angle within ±10°also has little effect on the lesion detectability.

Green tea, a leaf of the plant Camellia sinensis, is one of the most consumed traditional oriental beverages. Green tea has been considered a medicine and a healthful beverage since ancient times, but recently it has received a great deal of attention because of its antioxidants like polyphenols. Moreover, green tea contains amino acids, carbohydrates, proteins, chlorophyll, volatile compounds, minerals, and phytochemical components that are essential or helpful to human health. Depending on themanufacturing process, green teas are classified into several types. Among these, powdered green tea can be effective in the absorption of ingredients compare with other types of green tea since we take the beverage with powder itself. In this paper, the contents of general ingredients (moisture, proteins, fat, carbohydrates, and ash), minerals (Fe, Mg, Ca, Na, K, and P), hunter color values, and alcohol insoluble substance were determined in total of six powdered green teas commercialized in Korea and Japan.

The objective of this study is to investigate the difference of Organizational Citizenship Behavior between regular position and irregular position. Hence, our study is to analyze theoretically the relationship of activated increase of irregular position and organizational citizen behavior from a part of reducing the labor cost in the corporate's structural regulation. As a result, confronting IMF economic crisis, banks couldn't survive and vanished. So to maintain their existence, many banks is remodeling organization and correcting employment and introducing new management innovation techniques, which is very important and no wonder to do that. But we can find that individual bank is controling their employment intending to reduce labor cost. Of course in the environment of keen competition there is no other choice. However, we must examine throughly that reducing labor cast for a short term can follow for banks to strengthen the competitiveness in the long view.

Carotenoids 식이와 알코올이 혈액학적 성분과 간조직에 미치는 영향에 관한 연구

조만희,김연선,이상한,우기민,장예진,김창세 순천향의학연구소 1999 Journal of Soonchunhyang Medical Science Vol.5 No.2

Alcohol is well known agent which can damage the human tissues such as liver via stimulating lipid peroxidation and storage, denaturation of macromolecules, and inhibiting protein metabolism. On the other hand, carotenoids in addition to vitamins A, C, E and lipoic acid, play important roles in protecting these oxidative damages as well as preventing the production of free radicals. This study was carried out to elucidate the precise effects of alcohol administration into rats on the antioxidative functions of dietary carotenoids and isolated β-carotene, and to find out any parameters to uncover more detailed biochemical mechanisms of these agents. For these purposes, two different approaches were performed: 1) examination of the changes in hematological parameters (e.g., total proteins, A/G ratio, ALT/AST et. al) and statistical correlations among inter- and intragroups, 2) examination of the histopathological changes by an electron microscope. The results were analyzed and summarized as following; (1) Carrot diet for one week caused a slight increase in albumin. A/G ratio and AST levels, and a slight decrease in ALT, ALP, BUN and uric acid levels. Two-week alcohol administration following carrot diet increased total proteins, albumin A/G ratio and BUN levels. However, both groups were shown to have little significant changes in cholesterol concentrations. (2) Cheese diet for one week caused a significant increase in total proteins, albumin, AST, ALP, uric acid and total cholesterol levels, and a significant decrease in A/G ratio and glucose concentrations. However, two-week β-carotene diet following cheese intake increased total proteins albumin, A/G ratio, BUN and total cholesterol levels, whereas AST, ALT, ALP and uric acid levels were decreased. (3) Alcohol administration for one week caused an increase in AST activities and a decrease in total proteins, albumin, ALT, ALP and BUN levels. A successive β-carotene diet following alcohol administration increased total proteins, albumin, ALT, ALP and BUN levels, whereas decreased AST and uric acid levels. However, there were not significant changes in A/G ratio, glucose and total cholesterol levels in both groups. (4) β-carotene diet for one week caused a slight increase in albumin, glucose, AST and uric acid levels, and a slight decrease in ALP and BUN levels. Two-weeks alcohol administration following β-carotene diet increased albumin, glucose, BUN and total cholesterol levels, whereas decreased AST, ALT, ALP and uric acid levels. (5) Although the pathological investigation on the liver did not reveal significant changes, cheese diet group (CH-BC/1-CH) was shown to have some lipid deposits. Some results were unexpected and different from typical hematological changes shown by other researchers. Nonetheless, these results strongly suggest that the liver damage or hepatism caused by alcohol intake affects many kinds of biochemical metabolisms, which results in significant changes in many hematological parameters. In addition, dietary carotenoid and isolated β-carotene were shown to have protective roles against the biochemical changes by alcohol intake.

Naringenin is a bioactive flavanone containing antioxidative, anti-inflammatory, and anticarcinogenic properties. The inhibitory effects on hyaluronidase of naringenin and its novel derivatives were evaluated. Among these flavonoids at 200 μM concentration, 7-O-butyl naringenin had the highest inhibitory effect on hyaluronidase with 44.84%. In addition, For naringenin at concentrations of 0, 150, and 190 μM, the apparent Michaelis constants (appKm) were calculated to be 0.60±0.02, 0.43±0.02, and 0.41±0.01 ㎎/㎖ of substrate, respectively; for 7-O-butyl naringenin at 0, 20, and 30 μM concentrations, those were 0.44±0.03 and 0.27±0.03 ㎎/㎖, respectively. The Vmax values at 150 and 190 μM naringenin were 0.59±0.02 and 0.56±0.01 ㎎/㎖/min, respectively; and those at 20 and 30 μM 7-O-butyl naringenin were 0.50±0.02 and 0.33±0.02 ㎎/㎖/min, respectively. However, the slopes of each inhibitory reaction were not significantly different. Therefore, naringenin and 7-O-butyl naringenin were shown to be uncompetitive inhibitors. These results demonstrate the potential use of 7-O-butyl naringenin as an anti-inflammatory substance.

MYB transcription factor isolated from <i>Raphanus sativus</i> enhances anthocyanin accumulation in chrysanthemum cultivars

Kee, Eun Sun,Naing, Aung Htay,Lim, Sun Hyung,Han, Jeung Sul,Kim, Chang Kil Springer Berlin Heidelberg 2016 3 Biotech Vol.6 No.1

<P>A MYB transcription factor gene, <I>RsMYB1</I>, from radish was introduced into the chrysanthemum cultivars ‘Peach ND’, ‘Peach Red’, and ‘Vivid Scarlet’ under the control of the cauliflower mosaic virus 35S promoter. Presence of <I>RsMYB1</I> in transgenic lines was confirmed using polymerase chain reaction (PCR). Results of reverse-transcription-PCR analysis revealed that the expression of <I>RsMYB1</I> was stable in all transgenic lines and could enhance the expression levels of three key biosynthetic genes (<I>F3H</I>, <I>DFR</I>, and <I>ANS</I>) involved in anthocyanin production. Accordingly, anthocyanin content was significantly higher in transgenic lines than in control of all the cultivars, although the increasement was not visually observed in any of the transgenic lines. Therefore, these results demonstrate that <I>RsMYB1</I> has potential to enhance anthocyanin content in the chrysanthemums.</P>
