  • In order to determine chemical components of onion flesh and peel, general nutrients, vitamin C, and total flavonoids were measured. Onion peel showed less moisture (14.3%) and no vitamin C compared to onion flesh. Onion peel contained more amounts of total flavonoids compared to onion flesh. In addition, the inhibitory effects of solvent extracts from onion flesh and peel on $H_2O_$-induced oxidative stress and growth of cancer cell lines (AGS human gastric adenocarcinoma and HT-29 human colon cancer cells) were investigated. Acetone with methylene chloride (A+M) and methanol (MeOH) extracts from onion flesh and peel appeared to significantly reduce the levels of intracellular reactive oxygen species (ROS) (p<0.05) and a greater antioxidant effect was observed in onion peel. Among fractions, 85% aq. methanol showed a higher protective activity against oxidative stress in both flesh and peel and there was no effect in the water and hexane fractions. The growth of cancer cells exposed to medium containing extracts and fractions from onion flesh and peel was inhibited dose-dependently. The growth of AGS was inhibited more in both flesh and peel compared to HT-29, and onion peel was more effective than onion flesh. Among fractions, 85% aq. methanol showed the greatest effect on growth inhibition in both flesh and peel. $IC_{50}$ values of 85% aq. methanol fraction from onion flesh and peel on AGS were 0.04 and 0.03 mg/ml, respectively, while those on HT-29 were 0.23 and 0.04 mg/ml. From our results, 85% aq. methanol fraction had an inhibitory effect against oxidative stress and growth of cancer cells, suggesting that it may contain biological active compounds.

The subjects for Oriental nursing organization, human affair management, and control function were nineteen Oriental medical center in Oriental University Medical Center, Korea. Data were collected from November, 2002 to February, 2003 with questionnaire. Data analysis was done by SPSS PC+ 12 program. Frequency, percentage, and minimum/maximum values were used for investment contents, and frequency and percentage were used for conversion process and output contents. 1. The input factors of oriental nursing management system The objective's western hospital career was over five years of one hundred and seventy-five(73.2%) persons. Nursing in-service education was performed in fourteen hospitals(77.8%). Two hundreds(83.7%) were pro to oriental nurse system. Only four hospitals(22.2%) had independent budget in nursing division. Nursing staff allocation to the bed was from 2.8:1 to 9.06:1 respectively, with a big gap of the rate following the hospitals. 2. The conversion factors of oriental nursing system 1) Oriental nursing system Oriental hospital nursing system was organized independently in ten hospitals among eighteen hospitals. The recruitment of nurses which was a vital role of the nursing division of the hospital was mostly(79%) opened. The education to develope nursing personnels was through in-service one in 97.4%. Education for oriental nursing and management was performed in 42.1%(eight hospitals) and that for reserves was done in 36.8%(seven hospitals). Administration for nursing education by nursing division was 68.5%(thirteen hospitals). The post education evaluation was performed by report submission in 36.8%(seven hospitals), by written examination in 26.3%, by questionnaires in 21.1%, and by lecture presentation in 15.8% subsequently. The directorial meeting for the nursing directors was attended by 84.2%(sixteen hospitals), and the meeting type was the medical executive and support division executive meeting in 55.6%(ten hospitals) and the personnel management in 39.6%(seven hospitals). 2) The actual conditions of oriental nursing personnel management The reason of working in oriental hospital was by voluntary in 67.1%(a hundred and sixty persons), by nursing department order in 28.0%(sixty-seven persons), and by others in 5.0%(twelve persons) respectively. The shift form was a three-shifts one in 94.7%(eighteen hospitals), a two-shift one in only one hospital. Duty assignment was functional in 52.6%(ten hospitals), team and functional in 26.3%(five hospitals) and no team alone. Promotion manual was present at 68.4%(thirteen hospitals) and the competency essentials comprised of performance evaluation in 79%, interview, written examination, training result, study result subsequently. No labor union existed in 79%(fifteen hospitals) 3) Oriental nursing preceptor system There were five oriental hospitals(27.7%) administering the preceptor utilization model, which showed lower rate than the twenty-two medical university hospitals in Seoul in which fifteen hospitals (72.7%) were having the system. To the question of necessity of oriental nurse system asked to the objectives of two hundred and thirty-nine with more than three year-experience in oriental hospital, two hundred persons(83.7%) answered positively. 4) The control of oriental nursing The evaluation results from the target hospitals were mostly not opened in 89.4% of oriental hospitals. Thirteen hospitals(68.3%) had evaluation system of direct managers and the next were three hospitals(15.8%) of direct managers and selves. There was one hospital(5.3% each) where fellows and superiors, fellows, and inferiors' evaluation was performed and no hospital where superiors, fellows, inferiors and selves, and superiors, fellows and selves' evaluation was performed.

  • Objectives : The purpose of this study is to analyze the distribution, relationship, prognosis and improvement score of idiopathic facial palsy inpatients according to constitutional differentiation ; Sasang constition, Hyungsang classification, Sasang constition combined with Hyungsang classification. Methods : A study was done on 102 patients who were diagnosed and treated as idiopathic facial palsy from April 2012 to Nomember 2012 at the Department of Acupuncture and Moxibution Medicine, Dong-eui Oriental University Hospital. Medical records of inpatinets who underwent facial ENoG, NET test were analyzed. Changes of HBGS grade and Yanagihara's score were also evaluated. We classified inpaients acording to Sasang constitution by consulting to Department of Sasang constitutinal medicine, and to Hyungsang classification(Dam-body, Bangkwang-body) by measuring under medical system of 3D facial shapes(RS-400FL). The constitutional differentiation and general characteristics were initially analyzed, and valuse on ENoG, NET were correlated with constitutinal differentiation. Results of HBGS and Yanagihara's score were also correlated with constitutinal differentiation. Results : 1. Each 39.2 percent of idiopathic facial palsy inpatients were the Taeeumin and Soyangin, 21.6 percent were the Soeumin. 2. 75.5 percent of idiopathic facial palsy inpatients were the Bangkwang-body, 24.5 percent were the Dam-body. 3. 34.3 percent of idiopathic facial palsy inpatinets were the Taeeum-Bangkwang, 21.6 percent were the Soyang-Bangkwang, 19.6 percent were the Soeum-Bangkwang, 17.6 percent were the Soyang-Dam, 4.9 percent were the Taeem-Dam, 2 percent were the Soeum-Dam. 4. By sex, the each ratio of Taeeumin, Soeumin, Bangkwang-body, Taeeum-Bangkwang, Soeum-Bangkwang, Soyang-Bangkwang was higher in female, that of Dam-body, Taeeum-Dam, Soyang-Dam was higher in male. 5. By relations between Sasang constitution and Hyungsang classification, the each ratio of Taeeumin and Soeumin was higher in Bangkwang-body. 6. By values on ENoG and NET, evaluations of HBGS's grade and Yanagihara's score, there were no significant difference. Conclusions : In idiopathic facial palsy inpatients, the proportion of Taeeum and Soyang among the Sasang constitution was higher, that of Dam among the Hyungsang classification was higher, that of Taeeum-Bangkwang among the Sasang combined with Hyungsang was the highest. It would seem that Bangkwang-body, female were closely related to Taeeumin, Soeumin. Also, Dam-body were closely related to male. But when comparing groups, there was no statistically significant difference in prognosis and improvement.

  • The CA(Controlled Atmosphere) storage of cherry tomatoes were carried out under seven gas compositions including air. The weight loss of cherry tomatoes progressively increased with storage time. In the case of cherry tomatoes stored under CA conditions, increment of weight loss was reduced. However, cherry tomatoes (in air) tut about 15% weight at the end of storage. In CA stored cherry tomatoes lost about 10% weight at the same time. General trend was a decrease in titratable acidity with storage time. In air md 6.4% O$_2$, 4.2% CO$_2$, titratable acidity was lower than that in other storage conditions. During storage of cherry tomatoes, soluble solids increased till 8 days of storage, and then decreased. Stored cherry tomatoes in air and 6.4% O$_2$+4.2% CO$_2$ have lower values. Lycopene contents of cherry tomatoes with 6% O$_2$ storage condition increased and cherry tomatoes with 1% O$_2$+6% CO$_2$ and 3% O$_2$+3.1% CO$_2$maintained s initial contents. In air, flesh firmness decrease till 8 days, and then increase. At 1% O$_2$+6% CO$_2$ ethanol contents were ten times to that of other experimental conditions. Air and 6% O$_2$+7.8% CO$_2$ condition had lowest value for the ethanol content. In changes of organic acid and citric acid decreased slowly during storage, malic acid in air and below 3% O$_2$was disappeared at 8 days. Above 4% O$_2$concentration malic acid contents were maintained till 16 days. In over all acceptability, air and 6.4% O$_2$+7.8% CO$_2$ condition took a good score from the panel. Quality of stored cherry tomatoes was not edible condition in 1% O$_2$+6% CO$_2$. CA storage cherry tomatoes took a good score in firmness and juiciness where as control received good score in color and sweetness. This result was explained that in air ad 6.4% O$_2$+7.8% CO$_2$stored cherry tomato was ripened and full color development, but in CA was break stage because of suppressed ripening.

  • This study compared and analyzed the physiochemical and quality characteristics of young radish kimchi made with YR-FNC or YR-GC cultivated by organic farming as well as kimchi made with young radish cultivated by chemical composting/general farming (YR-Control). YR-Control showed higher contents of water and crude protein than YR-FNC and YR-GC kimchi but lower contents of crude ash, dietary fiber, and vitamin C. YR-FNC and YR-GC kimchi also showed higher contents of P and Cu than YR-Control but lower contents of N, K, Ca, Mg, Fe, and Zn. YR-Control fermentation progressed faster than that of YR-FNC or YR-GC after 24 days, and YR-Control more rapidly reached an appropriate pH. On the other hand, YR-FNC and YR-GC kimchi fermentation progressed slow and did not reach a pH level below 5.3. For period of fermentation, YR-Control and YR-FNC kimchi showed no significant difference in reducing sugar content, whereas that of YR-GC kimchi decreased significantly after 24 days of fermentation (P<0.002). YR-FNC and YR-GC kimchi showed 1.5~3 times higher total polyphenol and flavonoid contents than YR-Control at the beginning of fermentation, whereas YR-Control and YR-FNC kimchi showed a significant increase in total polyphenol and flavonoid contents during the fermentation period. By day 7 of fermentation, YR-FNC kimchi showed higher contents of lactic acid bacteria and total microbes than YR-Control. In the sensory evaluation, YR-FNC and YR-GC kimchi showed higher preference values than YR-Control. Therefore, kimchi made from young radish cultivated by organic farming has a longer freshness period than control kimchi and is characterized by excellent sensory quality, increased physiological contents, and improved beneficial health effects.

  • This study was performed to investigate changes in ${\gamma}$-aminobutyric acid (GABA) and isoflavones in traditional Korean Doenjang according to ripening periods. The traditional Korean Doenjang used in this research was produced at Seowon Agricultural Cooperative in Gangwon-do Province, and samples fermented for periods of 1, 3, 5, 7, and 10 years were used. Doenjang that was not fermented after production was used as a control group. The analysis results of general constituents indicated a decreasing tendency for moisture after a momentary increase until three years of fermentation. The pH and Hunter color values of the Doenjang samples decreased overtime. In the case of amino acids, generally there were no notable differences during fermentation, but glutamic acid, the precursor of GABA, significantly decreased with fermentation. GABA content for the control group was $24.9{\pm}0.8\;mg$/kg, while the traditional Korean Doenjang fermented for 1 year contained $43.8{\pm}0.2\;mg$/kg and after 3 years it increased to $120.6{\pm}3.9\;mg$/kg. Furthermore, samples fermented for 5 and 7 years contained $569.5{\pm}3.9\;mg$/kg and $930.7{\pm}7.1\;mg$/kg, respectively, and a 10 year old specimen had 77 times more GABA than the control group, with $1,938.7{\pm}4.8\;mg$/kg. This confirmed that GABA content increased with fermentation time. There were no significant differences in the isoflavone glycosides daidzin, genistin, and glycitin, but genistein and daidzein, which are aglycones, increased along with fermentation period by the actions of enzymes and microorganisms during fermentation.

  • This study was conducted to estimate the incidence and the degree of cigarette smoking and drinking among working men, and then to investigate the effects on blood pressure, various hematological indices and blood chemistry. The sample consisted of 2,287 male workers who had undertaken a general health check-up during the two-year period from January, 2000 to December, 2001. Such factors as blood pressure, blood glucose, lipid profiles, and liver function tests were determined and then analyzed with respect to the subjects smoking and/or drinking status. The major findings from this study are: 1. The drinking and smoking status have shown that 52.7% of participants were in the habit of both drinking and smoking while 11.6% were not associated with either. On the other hand 25.4% were involved only in drinking and 10.2% only in smoking. In the group smoking over 21 cigarettes per day over 30, the age group occupied the largest proportion at 20.1%. 2. Regarding the relationship between smoking and/or drinking status, and blood pressure, hematology and blood chemistry, the smoking and/or drinking group had significantly higher levels of blood pressure, both systolic and diastolic, Hb & Hct, TG, LDL-C, SGOT, and ${\gamma}$-GTP, than the non-smoking and/or non-drinking group. But HDL-C was significantly lower in the smoking group and significantly higher in the drinking group than the non-smoking/non-drinking group. 3. Regarding amount smoked, a larger number of cigarettes per day was significantly associated with the higher levels of blood pressure, systolic and diatolic, TG, TC, LDL-C, Hb, Hct, and ${\gamma}$-GTP. As for the amount druck, an increasing amount of alcohol intake was associated with rising levels of blood pressure, systolic and diatolic, TG, TC, LDL-C, HDL-C, Hb, SGOT, and ${\gamma}$-GTP. 4. Regarding the correlation among all the variables stated above, the smoking and drinking amount was shown to be in the positive correlation with blood pressure, both systolic and diastolic, TG, TC, Hb, and ${\gamma}$-GTP. On the contrary, LDL-C and HDL-C was in a positive correlation only with the amount drunk amount, and Hct only with the amount smoked. 5. As with systolic and diastolic blood pressure, the odds ratio of the smoking group was 2.35 and 2.58 compared to the non-smoking/drinking group. whereas it was 1.47 and 1.75 in the smoking/drinking group. Concerning serum lipids, the smoking/drinking group had 1.97 times the levels of TG in the non-smoking/non-drinking group, though the smoking group had 1.55 times the levels of HDL-C in the non-smoking/non-drinking group. As with liver function test results, the drinking group had 2.50 times and the smoking/drinking group had 4.41 times the levels of ${\gamma}$-GTP in the non-smoking/drinking group. respectively. The above results revealed that smoking and alcohol intake were effected the results of blood pressure and laboratory tests. Specifically, not only the smoking/drinking group but also those only smoking or only drinking were not as desirable as the non-smoking and non-drinking group to the results of blood pressure and laboratory tests.

  • The 3D stereoscopic image contents have been emerging as the blue chip of the contents market of the next generation since the . However, all the 3D contents created commercially in the country have failed to enter box office. It is because the quality of Korean 3D contents is much lower than that of overseas contents and also current 3D post production process is based on 2D. Considering all these facts, the 3D editing process has connection with the quality of contents. The current 3D editing processes of the production case of are using the way that edits with the system on basis of 2D, followed by checking with 3D display system and modifying, if there are any problems. In order to improve those conditions, I suggest that the 3D editing process contain more objectivity by visualizing the depth data applied in some composition work such as Disparity map, Depth map, and the current 3D editing process. The proposed process has been used in the music drama , comparing with those of the film . The 3D values could be checked among cuts which have been changed a lot since those of , while the 3D value of drew an equal result in general. Since the current process is based on an artist's subjective sense of 3D, it could be changed according to the condition and state of the artist. Furthermore, it is impossible for us to predict the positive range, so it is apprehended that the cubic effect of space might be perverted by showing each different 3D value according to cuts in the same space or a limited space. On the other hand, the objective 3D editing by applying the visualization of depth data can adjust itself to the cubic effect of the same space and the whole content equally, which will enrich the 3D contents. It will even be able to solve some problems such as distortion of cubic effect and visual fatigue, etc.

  • In this study, we analyzed the nutritional ingredients of drone pupae (16th to 20th instar old) to evaluate the value of bee products and provide basic data for product diversification, and the extracts prepared using these pupae were tested for physiological activity. According to the analysis of the general ingredients of the freeze-dried powder of these bee pupae, the moisture, crude protein, crude fat, and crude ash was 1.69 ± 0.07%, 48.52 ± 0.20%, 23.41 ± 0.14%, and 4.05 ± 0.02%, respectively. Vitamin C and vitamin E were 14.92 ± 0.52 mg/100 g and 6.06 ± 0.11 mg α-TE/100 g, respectively. Regarding minerals, the highest content of K (1349.13 ± 34.57 mg/100 g) and P (1323.55 ± 43.85 mg/100 g) was observed and Ca and Fe were 55.43 ± 1.51 mg/100 g and 5.49 ± 0.19 mg/100 g, respectively. The fatty acids of the water extracted freeze-dried pupae powder accounted for approximately 59.62 of saturated fatty acids and 40.38 of unsaturated fatty acids, and high-quality fatty acids such as palmitic acid (C16:0) was 35.49 ± 0.08 and oleic acid (C18:1, n-9) was 35.91 ± 0.22 (g/100 g total fatty acids). The total amino acid content was 38.99 ± 2.63 g/100 g and the free amino acid was a total of 5129.04 mg/100 g, of which 1257.68 mg/100 g was proline and 759.12 mg/100 g glutamic acid. The DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity of the drone pupae extract showed values of 0.8 for distilled water extract, 3.2 for 50% EtOH extract, 6.4 for 70% EtOH extract, and approximately 90% for 32 ㎍/mL for 100% EtOH extract. These results suggest that the main compound contributing to the antioxidant activity is a polar compound, and it is highly likely to be a low-molecular protein or a free amino acid. In conclusion, the honey bee drone pupa is excellent as a food resource and can be utilized as a new functional material for food and functional food.

  • To obtain basic da1a on the preparation of Cudrania tricuspidata leaves tea, the quality and anti-oxidative characteristics of dried raw leaves (RT), pan-fired leaves tea (PT) and fermented leaves tea (FT) were investigated. General characteristics of RT, PT and FT, respectively, were: moisture content 18.47, 6.23 and 8.50%; crude protein content 17.77, 20.46 and 19.13%; and carbohydrate content 54.42, 62.52 and 61.96%. The crude lipid and ash contents were in the range 0.05 - 0.07% and 9.27 -10.74% respectively; the water soluble solid content was in the order FT > PT > RT and ranged from 23.10 - 37.38%; there were no significant differences in the total polyphenol content (815.24 - 835.16 mg%). Although $L^*$ values of PT (20.94) and FT (20.85) were lower than those of RT (34.71), the $a^*$ value in PT and the $b^*$ value in FT were highest. In all ethanol extracts the reducing power, electron-donating ability and superoxide dismutase (SOD)-like activity increased in a concentration-dependent manner. Furthermore, the activity in FT was higher than in PT or RT. The total free amino-acid content was higher in FT (1429.93 mg%) than RT (1108.94 mg%) or PT (833.13 mg%). The major amino acids were L-asparagine and L-valine in RT, L-cysteine and L-glutamic acid in PT and L-proline in FT. In a sensory evaluation of PT and FT, bitter and astringent tastes were decreased relative to RT, while sweet and savory tastes, flavor, color and overall acceptability were increased. These results indicate that FT bas a higher antioxidant effect and free-amino-acid content than PT, while the sensory quality of FT is similar to that of PT.
