  • The objective of this research was to find out the potential value of flaxseed as a dietary supplement as well as an edible oil resource. The characteristics of yellow flaxseed oil and brown flaxseed oil were compared to check which oil is better in the aspects of cooking purpose and of nutritional value. The quality of flaxseed oil was evaluated based on the composition of fatty acid, the content of phenolic compounds and the anti-oxidant activity. The total phenolics of yellow flaxseed oil and brown flaxseed oil were $10.78{\pm}0.46$ and $29.88{\pm}3.25mg/100g$, respectively. Their ${\gamma}$-tocopherol contents were 20.59 and 17.94 mg/100 g, respectively. Contents of linolenic acid were 56.60 and 31.38% and oleic acid were 18.24 and 39.16 %, respectively. Yellow flaxseed oil showed higher ratio of unsaturated fatty acid than brown flaxseed oil. However, brown flaxseed oil showed higher electron-donating abilities than brown flaxseed oil, which might be due to its higher content of phenolic compounds. In conclusion, flaxseed has a great potential as a good edible oil resource due to its high content of unsaturated fatty acid and anti-oxidant activity.

  • We developed an 4.5" $192{\times}64$ active matrix organic light-emitting diode display on a glass using organic thin-film transistor (OTFT) switching-arrays with two transistors and a capacitor in each sub-pixel. The OTFTs has bottom contact structure with a unique gate insulator and pentacene for the active layer. The width and length of the switching OTFT is $800{\mu}m$ and $10{\mu}m$ respectively and the driving OTFT has $1200{\mu}m$ channel width with the same channel length. On/off ratio, mobility, on-current of switching OTFT and on-current of driving OTFT were $10^6,0.3{\sim}0.5\;cm^2/V{\cdot}sec$, order of 10 ${\mu}A$ and over 100 ${\mu}A$, respectively. AMOLEDs composed of the OTFT switching arrays and OLEDs made using vacuum deposition method were fabricated and driven to make moving images, successfully.

  • It has been well known that the integrity of airway epithelium is important in developing of bronchial hyperreactivity or bronchial asthma. But the mechanisms underlying this nonspecific airway hyperresponsiveness are not yet determined. To evaluate the ability of guinea pig trachea to release an epithelium derived relaxing factor (EpDRF) which relax rat vascular smooth muscle, we performed the coaxial bioassay using guinea pig trachea and rat aorta. And to evaluate the nature of EpDRF we investigate the influence of methylene blue and indomethacin on the coaxial bioassay. Results were as follows. 1) Vascular smooth muscle mounted into the epithelium intact trachea which was precontracted with phenylephrine was relaxed by addition of histamine or acetylcholine. But vascular smooth muscle mounted into epithelium denuded trachea failed to be relaxed. 2) Epithelium dependent relaxation of vascular smooth muscle was not affected by pretreatment of methylene blue or indomethacin. These results strongly suggests that guinea pig tracheal epithelium releases EpDRF which is able to relax rat vascular smooth muscle. And EpDRF released by airway epithelium is not related to endothelium derived relaxing factor (EDRF) or cyclooxygenase products.

  • This experiment was conducted to find out the effects of mushroom cultivation on ozone susceptibility. The mushroom media in cultivation became softening well without bad Knell when it was soaked for 120 hours. The mushroom media softening on cultivating of oyster mushroom was good and fast when the concentration of gas condition ozone is high. The concentration of gas condition ozone must control at less than 0.02 ppm at the innoculation room, 0.03 ppm at the incubating room, must not use at the sprouting mom, less than 0.02 ppm at the growing room respectively. Also at the growing room, it removes the smell of mushroom, so has a protective effects of coming into mushroom fees and disease. When the concentration of 0.02 ppm liquid condition ozone was sprinkled, it was very useful in disease protection If it was input, the storage period of mushroom fruiting body was prolonged.

  • The present study was attempted to investigate the mutagenicities of carbonyl compounds(methyl glyoxal, glyoxal, diacetyl, dihydroxyacetone, glycolaldehyde, glyceraldehyde and furfural) derived from Maillard reaction toward Salmonella typhimurium TA 100(base-substitution mutant) without metabolic activation . And for further Investigation of mutagenicity mechanism including desmutagenicity, active oxygen scavengers (cysteine, ${\alpha}-tocopherol$, tris (hydroxymethyl) aminomethane, catalase, ascorbic acid) and reducing agents (glutathione, sodium bisulfite) were also used. Among carbonyl compounds tested, methyl glyoxal, glyoxal, dihydroxyacetone, glycolaldehyde and glyceraldehyde exhibited mutagenicities, and methyl glyoxal showed the strongest mutagenic activity. On the other hand , the mutagenicities of carbonyl compounds were significantly suppressed by cysteine, tris (hydroxymethyl) aminomethane, glutathione and sodium bisulfite. Also, these active oxygen scavengers and reducing agents alone did not show mutagenicity in the present study.

  • The expression and antibacterial. activity of recombinant human lactoferrin (hLf) was studied from meth­ylotrophic yeast Pichia pastoris. The gene encoding hLf, isolated from human breast cDNA library, was subcloned into the expression vector, pPIC3.5K under the control of AOX1 promoter. The gene was integrated into the host chromosome and was identified by Southern blotting. The expression of the integrated gene was investigated by RT-PCR, Northern blotting, SDS-PAGE and Western blotting. Discrete band corresponding to hLf was detected from the SDS-PAGE, which was confirmed by Western blotting. The expression was also confirmed by RT-PCR and Northern blotting. The antibacterial activity of the recombinant hLf (rhLf) was investigated using Staphy­lococcus aureus ATCC 6538P and Micrococcus flavus ATCC 10240 as test organisms. The rhLf showed strong antibacterial activities against the bacteria. Furthermore, many Gram-negative animal pathogens such as E.coli ATCC8739, 25922, and Salmonella typhimurium 114 and 115, Pseudomonas fluorescens ID 963 I, P. aeruginosa KCCM 11802, and Gram-positive bacteria Bacillus mesentericus were also inhibited in their growth by the rhLf.

  • This paper aims to present the ways to maximize educational effects and facilitate a curriculum renovation through the Specified Track Curriculum Development, a joint lecture system among local universities which is implemented by Busan Educational Alliance of Mechanical Engineering (BEAM) as part of New University for Regional Innovation(NURI), a government-sponsored project to facilitate a balanced regional development of Korea. The Specified Track Curriculum is a unified governing body joined by 4 universities of mechanical engineering departments with an emphasis on their specified academic fields(advanced hightech, environmental, marine and foundational machinery sectors), And the universities mutually recognize academic credits. The track (Specified-Track Curriculum) was carried out three times from winter semester in 2005 to the present and 486 students took the track course for two years. As a result, the track laid out a foundation for the first local joint lecture system in korea with the performance-oriented and students-tailored education, meeting needs of the new era and training efficiency. The graduates' employment rose to 8.5%, compared with that of 2005. According to recent survey conducted on companies employing the graduates, the satisfaction with the graduates' performance marked 9.4% improvement. The track also contributed to expanding human networks, facilitating the educational exchange of local universities.

  • Today, businesses have to respond with flexibility and speed to ever-changing customer demand and market opportunities. Service-oriented architecture (SOA) is the best methodology for minimizing the complexity and the cost of enterprise-level infrastructure and for maximizing the productivity and the flexibility of an enterprise. Most of the enterprise-level SOA delivery strategies deal with the top-down approach, which organization has to define the business processes, to model business services, and to find the required services or to develop new services. However, a lot of peoples want to maximally reuse legacy component-based systems as well as to deliver SOA into their organizations. In this paper, we propose a bottom-up approach for identifying business services with proper granularity. It can improve the reusability and maintenance of services by considering not data I/O of components of legacy applications but GUI event patterns. Our proposed method is applied to MIS with 129 GUIs and 13 components. As a result, the valiance of the coupling value of components is increased five times and three business services are distinctly exposed. It also provides a 49% improvement in reducing the relationship problems between services over a service identification method using only partitioning information of components.

  • Objective : The purpose of this case is to report the improvement after treatment about a patient with meralgia paresthetica. Methods : We treated the patient with acupuncture therapy and Herbal medication from 11th October 2004 to 15th October 2004 by evaluating femoral function with VAS score and R.O.M of femur joint. Results : After 5 times of treatment, this patient achieved excellent outcome following the technique, showing that clinical symptom as like heating sense, edema and pain was disappeared, VAS changed from 10 to 1 and there was no limitation of ROM of femur. Conclusions : Meralgia paresthetica is a symptom complex that includes numbness, paresthesias, and pain in the anterolateral thigh, which may result from either an entrapment neuropathy or a neuroma of the lateral femoral cutaneous nerve(LFCN). Oriental medical treatment for meralgia paresthetica resulted in satisfactory results by diminishing the symptoms progressively during the five days of treatment. Differential diagnosis was based on careful physical examination. More research of meralgia paresthetica is needed.

  • There is no doubt that distribution channels and services greatly satisfy consumers' desires. Lots of products and services, stimulate consumers to purchase products to relieve their depressed feeling/stress temporarily, leading them gradually to a shopping addiction. Shopping addiction generates lots of problems, damaging not only consumers themselves but also other consumers and the entire society. Therefore, the purposes of this study were 1) to examine psychological factors that affected addictive shopping orientation of consumers, 2) to explore the effects addictive shopping orientation on the post-purchase emotions(positive emotion/negative emotion), 3) to examine the effect of post-purchase emotions on post-purchase behaviors (repurchasing/refund and exchange/negative word of mouth). 4) the study explored the differences in terms of effects of addictive shopping orientations on post-purchase emotions and behaviors, depending on the retailing channel (online and off line). The study performed a questionnaire survey for female adults older than 18 years old, living Seoul and Pusan areas. By using 404 copies for questionnaires, factor analysis, reliability analysis, and Amos 7.0 were used for the data analysis. It was found that psychological variables, self-esteem, compensatory buying and impulsiveness, had significant effects on addictive shopping orientations. Addictive shopping orientations affect both positive and negative post-purchase emotions in case of off-line shopping. Negative post-purchase emotions have higher impact on the postpurchase behaviors than positive post-purchase emotions.
