  • Objects : This study has been carried out to assess the effects of the variable herbs on $IFN-{\gamma}$ secretion in the mouse spleen cell. Methods : 202 kinds of herb extracts were used to evaluate the $IFN-{\gamma}$ secretory distinction by each $1{\mu}g/ml$ and $10{\mu}g/ml$ density of water. All experimental herbs were grouped by oriental herbalogical method. But each herb had its independent variables. Results : The secretions increased in 20% of all herbal water. The density differences also make different effects on the secretion of $IFN-{\gamma}$. The secretion of IFN-${\gamma}$ inclosed in some kinds of herbs of IFN-${\gamma}$. It has representatively increased in Imperaetae Rhizoma(白茅根) of $1{\mu}g/ml$ and Notopterygii Rhizoma(羌活)of $10{\mu}g/ml$. $IFN-{\gamma}$ incresed in 12 kinds of heybs of both densities. The secretion of $IFN-{\gamma}$ decreased in some kinds of herbs of $IFN-{\gamma}$. It has representatively decreased in Moutan Radicis Cortex(蘇丹皮) of $1{\mu}g/ml$ and Angelicae Radix(富歸尾) of $10{\mu}g/ml$. $IFN-{\gamma}$ decreased in 18 kinds of herbs of both densities. In t oriental herb group, The secretion of $IFN-{\gamma}$ increased in Bang-Hyang-Hwa-Sup group(芳香化濕藥), He-Pyo group(解表藥), I-Su-Sam-SuP group(利水渗) The secretion of $IFN-{\gamma}$ decreased in Gu-Chung group(驅蟲藥), An-Sin group(安神藥). Su-Sap group(收澁) On-Li group(溫裏藥), I-Gi group(利氣藥). Conclusions : The result of this study will not only broaden applications of oriental medicine to biological therapy, but also form the basis of oriental medical therapy to find out the meaning of oriental classification.

  • Though, these days there are increasing many patient of insomnia, there was not considered literatual study on insomnia. So, the result of consideration about cause and process of insomnia from thirty kinds of literatures, are as follows. 1. Early literature like Huangjaenankyung(黃帝內經), Sanghanron(傷寒論) reffered to insomnia as accompanying symptom. on the other hand, Myung(明), Chung(淸)'s literatures reffered to that as chief symptom or distinguished chief symptom from accompanying symptom. 2. There were tendency of deductive expanding of various masters and tendency of induction of simple theory that was based on Huangjaenankyung(黃帝內經). 3. Huangjaenankyung(黃帝內經) showed basic process of the sleep disorder that 'exhausting of Yin and excess of Yang (陰盡陽盛)', protecting energy does not invade Yin portion(陽氣不入於陰). And Huangjaenankyung(黃帝內經) showed cause of insomnia that deficiency of vital energy and blood, imbalanced of spleen and stomach, a fever as a invasion in the outside, lung system's disease. This became a basic cause and process of the sleep disorder in ancient period. 4. Sanghanron(傷寒論) occurred to insomnia as accompanying symptom in progress, remedy of a fever invaded outside, Kumkyeyoriak showed as origination in weakness, fatique, various diseases. Out of that, there is a significance in description of insomnia from some disease like histery or neurosis. 5. Jaebyungwonhuron(諸病源候論), Chunkumbang(千金方), Kukbangseo(局方書.) occured to a fire of heart(心慤) and a deficiency of heart and gall bladder(心膽虛) in defails. Insomnia is caused by agony of seven emotion, delivering of a child, are similar to insomnia is caused by psychologic disorders. Injaesanghanyusu(仁劑傷寒類書) occured to exhausting of Yin and excess of Yang (陰盡陽盛), imbalanced of stomach(胃不和) invasion of coldness(傷寒) are brought a conclusion of assumption of sap(津液耗損) brought about unreturn of yin energy. 6. Manbyunghuechum(萬病回春) in Myung period (明代) made much of portion of phlegm's influence about spiritual function. Kyungakjunsu(景岳全書) valued much of treatment divided according to excess and deficiency. Junginmaekchi(證因脈治) occurred to concept of pyorihesil(表裏虛實), Dongyibokam(東醫寶鑑) synthesised various theories. 7. Hyuljungron(血證論), Byunjungkimun(辨證奇聞), Suksilbirok(石室秘錄) made much of surprisemeni(驚恐) Consideration(思慮), liver's dryness(肝燥) is caused by liver's weakness(肝虛), imbalance of haert -kidney(心腎不交), seven emotion(七情). Especially, ftyujungchijae(類證治載) said that heart, liver, gall-bladder, kidney, surprisment, consideration baought to a conclusion of inbalance of Yang and Yin (陽不交陰). There is a tendency in literature mostly that literature showed separation of insomnia as a chief symptom. 8. These days there are increasing many patient of insomnia. So, it is needed to study about insomnia as a psychologic disease. Saying in conclusion, it is needed that we have to recognize in modern style based on ancient style of cause and process of insomnia. It is regarded to study about insomnia definitely and experimently.

  • Tomato yellow leaf curl virus (TYLCV), a newly reported Geminivirus from tomato, generated recently large economic losses in Korea. Development of a fast and precise genetic diagnosis technique for detecting TYLCV which Agricultural research and extension services can utilize easy and handy is very important to prevent yield losses. Virion Capture (VC)/PCR is a simple, accurate and economical genetic detection method without any works or commercial kits for the extraction of the nucleic acid from the infected plants. Primers of twenty two for detection of TYLCV were designed and tested with extracted total DNA or crude sap from tomato leaf infected with TYLCV and healthy plant. Nine primers for total DNA using conventional PCR and another 9 primers for VC/PCR were selected eventually. Primers of six having same specificity were selected from the two methods and tested with other Geminivirus, Tobacco leaf curl virus (TLCV) by VC/PCR. Finally specific primers of four were selected for detection of TYLCV using VC/PCR, and Deng (540, 541), a degenerate primer for Geminivirus reported in 1996, was also developed for VC/PCR.

  • The existing preservation methods are difficult to be applied to a large dimension log which is needed for making traditional wooden ship 'Jalur' in Riau Province. Novel techniques to provide the use of readily available species to replace traditional species alternative were investigated. These included infusion and a combination of injection and bandage-wrapping methods for preserving living trees of Balam (Macaranga conifera (Rchb.f. & Zoll.) Müll.Arg.) and Bintangor (Calophyllum soulattri Burm.f.). Water-based boron compounds were applied as wood preservatives. In total, 18 discs from the bottom, middle, and top of four trees and two controls were used. Trees undergoing treatment were also used to see how wood anatomical structure might affect the boron penetration. The overall aim was to identify the best method for use in Jalur manufacturing. The results showed that in infused Balam tree where the hose position for the preservative intake was deep (10-15 cm from the bark), no boron compound was observed in the outer sapwood. Combination of injection and bandage-wrapping method gave higher percentage of boron penetration at bottom and middle of Balam tree. However, infused Bintangor showed 100% boron penetration. The larger vessel diameter, the absence of tyloses, and the simple perforation plates in Bintangor wood were likely to have contributed to the higher penetration of boron. The combination of bandage-wrapping and infusion, or alternatively by infusing the living trees close to the bark, and at as low as position in the stem gives better protection when treatments are applied to living trees.

  • This study was performed to survey the general feature of reservoir sediment in Daecheong, Sapkyo and Kumkang reservoir. For investigations, sediments were sampled at four sites in Dae-Cheong and two sites in SapKyo and Kumkang in June and October. The items for investigation are as follows; water content, loss on ignition(IG), porosity of sediment, contents of element such as hydrogen, nitrogen, carbon, phosphorus contents and nutrient release rates. Loss on ignition was measured to determine the contents of organic substance. And its ranges were determined 2.4~16.2% in Daecheong reservoir, 5.6~27.9% in Sapkyo and 4.8~18.7% in Kumkang reservoir. And, total phosphorus contents in sediments were measured $677{\sim}5,238{\mu}g/g$ in Daecheong, $780{\sim}1,417{\mu}g/g$ in Sapkyo and $604{\sim}1,452{\mu}g/g$ in Kumkang reservoir. And release rates of nutrients were calculated $0.05{\sim}8.63mgP/m^2day$ and $4.99{\sim}36.56mgN/m^2day$ in Daecheong, $1.83{\times}10^{-3}{\sim}3.23{\times}10^{-2}mgP/m^2day$ and $1.97{\sim}.22mgN/m^2day$ in Sapkyo, $8.31{\times}10^{-3}{\sim}6.51{\times}10^{-2}mgP/m^2day$ and $0.89{\sim}4.42mgN/m^2day$ in Kumkang reservoir, respectively. And this study attempted to determine the humus level of sediments. As a result of elemental analysis, C/N ratio was determined 3.0~13.1 in Daecheong reservoir, 6.5~13.0 in Sapkyo and 3.6~12.6 in Kumkang reservoir, respectively. From the elemental analysis, humus levels of reservoirs were changed from mesohumic to oligohumic state in all reservoirs.

  • This study were conducted to investigate the influence of chilling on photosynthetic rate, root activity, contents of total sugars and fatty acids of cucumber seedlings grown in a greenhouse. Even though photosynthetic activity of seedlings exposed to $0^{\circ}C$ for 5 hours was little or insignificantly influenced, it was reduced by 52.8% and 67.7% in seedlings exposed to the same temperature for an extended 10 and 24 hours, respectively. Photosynthetic rate decreased significantly when seedlings were illuminated, as compared to continuously held under darkness, during 15 hours of chilling treatment at 3$^{\circ}C$. Recovery of photosynthetic ability was also retarded by illumination during a recovery period after chilling treatment. Root activity, as measured by the oxidation power of $\alpha$-naphtylamine, was significantly reduced by chilling treatment at 0 to 6$^{\circ}C$, but amount of bleeding xylem sap collected at 40 days after chilling treatment was not significantly different among treatments. Total sugar content increased by 12 and 23% as compared to the control in seedlings chilled for 24 hours, respectively, at 3$^{\circ}C$. Contents of unsaturated linolenic and oleic acids increased, while content of saturated palmitic acid decreased with chilling treatment.

  • Salt, or sodium chloride (NaCl), is a critical ingredient in many foods. It has roles in the flavor profiles of food products, textures of foods and preservation of foods against microbes. However, it increases risks of hypertension and is closely related to the development of cardiovascular disease. In recent years, health concerns related to sodium intake caused an increased demand for salt-reduced products in worldwide; it became necessary to develop natural salt-alternative products that are globally competitive. In a recent study, researchers succeeded in obtaining a natural salt enhancer through the hydrolysis of vegetable- and animal-matter mixtures. This study used various methods to identify and quantify peptide-containing arginine as a salt-alternative peptide (SAP) in an optimum combination. Arginine, or dipeptide-containing arginine, was analyzed as a standard substance using an NMR spectroscopy. The NMR carbon signal of the guanidine group of the standard substance was verified in a similar location (the L-arginine (Arg) was 156.8 ppm, the Arg-Alanine was 156.4 ppm and the Arg-Serine was 156.4 ppm). The results suggested that it is possible to analyze peptide-containing arginine quantitatively through the hydrolysis of vegetable- and animal-matter mixtures.

  • Researches on the introduction of ERP system kept on examining the critical successful factors (CSFs) that focus on factors to achieve effectively successful projects, and trying to measuring the actual effectiveness of the introduction of ERP system. However, most of the preceding researches on the effectiveness of the introduction of ERP system that was searching devoted effects has been ceased, and actually even researches on the economical results have just done the basic cognitive evaluation of result indicators by many questionnaires instead of objective measuring values, because of the difficulty of measuring the evaluation of the result. Moreover, researches on positive effects of the introduction of ERP on enterprise results and researches that failed to give advantageous effects showed different results each other. And a part of researches reported that only a part of result indicators were partially affected. In this research, we investigated Korean large enterprises or middle-sized enterprises in manufacture industry that introduces SAP R/3 and Oracle package to compare their quantitative financial results after the introduction of ERP system, in order to measure the effects of the ERP system. First, we evaluated the difference of the quantitative financial results before and after the introduction of the ERP system. Second, we evaluated the opportunities shown by the effects after the introduction of the ERP system. Third, we removed the sample of the exchange crisis (IMF) and executed the additional analysis to reflect the average increasing and decreasing rate in the industry, so that pure evaluation can be achieved. Inherent limits of precedent researches are removed and practical effects of the pure introduction of the ERP system are evaluated, so the research of this research is significant. The result of this research is as follows. Because of the introduction of ERP, the rate of turnover of inventory property has increased and sales of preparation inventory property have decreased so that more effective inventory property management has been achieved. Moreover, preparation sales of labor costs and preparation sales of the number of employees have decreased to show the effect of the reduction of labor costs. However, it could no be concluded that we could increase the profit due to the introduction of ERP system. Due to the introduction of ERP, although we concluded that the return on assets (ROA) and the additional value of one-person employee statistically showed obvious differences and increased, the return on equity failed to show obvious differences after the process of introduction of ERP.
