  • As the development of national lands increase, the necessity to develop less favorable terrain also increases. It also becomes more difficult and complicated to provide access that is both economical and safe from contributing to soil erosion on roadsides and to londscape damages. Because of the increased and justified emphasis upon environmental degradation, proper stabilization of the cut-and bank slopes of roadsides, plant sites and building sites in Korea requires careful planning as well as execution of the constructions. All fill slopes should be compacted to a degree consistent with design standards and material properties. Drainage facilities should be provided to prevent damaging concentrations of surface runoff and to avoid high pore pressures in cuts and fills. All surfaces of cut-fill slopes should be revegetated with suitable species as soon as possible after construction. To stabilize the cut-fill slopes of highway roadsides should be considerded the factor of stabilization as well as landscape conservation especially. Such basic influences as the effects of vegetations on water balance of rain fall, on the control of surface erosion and on the surface slope failures are briefly discussed in the report.

  • Rhus verniciflua Stokes (RVS) has been used as a food supplement and a traditional herbal medicine for a men's sexual enhancement. In this study, we prepared a flavonoid fraction (RWE) from a hot water extract of RVS and its influence on sexual behavior was studied in male rats which were orally administered varying doses of RWE for 2 weeks. All doses of RWE stimulated sexual behavior in male rats such as reducing mounting latency and enhancing mount frequencies. However, intermission numbers were not changed and none of group can observe the ejaculation during behavioral testing time 5 min. Testosterone levels were Increased about 0$\∼$53$\%$ and 92$\∼$164$\%$ by the treatment of RWE for 1 and 2 weeks, respectively. However, estrogen levels in male rats tended to decrease in a dose dependent manner of RWE. At the dose of RWE 200 mg/kg, estrogen level was reduced to 77.5$\%$ and 70.3$\%$ of control after 1 and 2 weeks treatment. These findings suggest that the Rhus flavonoid fraction can stimulate the androgen-dependent male sexual behavior and it can be applied to the material of functional food for enhancing the sexual function.

  • The traditional Asian medicinal herb, roots of Astragalus (A.) membranaceus (Leguminosae), is used for many purposes, some of which are purported to stimulate the release of growth hormone in vivo. Extracts of A. membranaceus were tested to determine whether they stimulate the release of growth hormone in rat pituitary cell culture. A. membranaceus was extracted sequentially with 80% ethanol (fraction A), n-hexane (fraction B); the test compound from the herbal extraction was isolated using silica gel column chromatography and was identified with spectral data. Test compound was also extracted by traditional boiling water methods. Induction of growth hormone in pituitary cell culture was conducted with isolated compounds and extracted fractions of A. Radix (dried roots of A. membranaceus). The fraction A was not active in the rat pituitary cell culture, but the fraction B derived from the ethanol fraction stimulated the release of growth hormone in culture. Six compounds from fraction B (1-6) were isolated and identified previously. The compounds 1,2-benzendicarboxylic acid diisononylester (1), $\beta$-sitosterol (2), and 3-Ο-$\beta$-D-galactopyranosyl-$\beta$-sitosterol (5) did not induce growth hormone release in the culture. Formononetin (3), 9Z, 12Z-octadecadienoic acid (4), stigmast-4-en-6$\beta$-o1-3-one (6) and 98-E, a mixture of 1'-9, 12-octadecadienoic acid (Z,Z)-2',3'-dihydroxy-propylester (7) and 1'-hexadecanoic acid-2',3'-dihydroxy-propylester (8) stimulated the release of growth hormone in the rat pituitary cell culture significantly compared to the control. In conclusions, four compounds isolated from extracts of A. Radix induced growth hormone release in the rat pituitary cell culture. The 98-E isolate was the most active inducer of growth hormone release.

  • A liquid chromatographic method with tandom spectrometric detection (LC/MS/MS) for the simultaneous determination of doxifluridine and its active metabolite, 5-fluorouracil (5-FU) was developed over the concentration range of $5{\sim}2000$ ng/ml, respectively. Doxifluridine, 5-FU and internal standard, 5-chlorouracil (5-CU), were extracted from liver and intestine tissue via protein precipitation. Acetonitrile was used as the extraction solvent and the supernatant was evaporated and reconstructed in mobile phase. Optimum chromatographic separation was achieved on a Agilent Zorbax $C_{18}$ ($100\;mm{\times}2.1\;mm$, $3.5\;{\mu}m$) column with mobile phase run in isocratic with methanol : water (20 : 80, v/v). The flow rate was 0.2 ml/min with total cycle time of 5 min. The lower limit of quantification was validated at 5.0 ng/ml of liver and intestine tissue, for both doxifluridine and 5-FU, respectively. The intra-day and inter-day precision and accuracy of quality control (QC) samples were <11% coefficient of variation and <7% relative error from theoretical concentration for both analytes. In addition, the special designed stability study was performed, because the metabolism of doxifluridine occurs spontaneously even in ice bath for monkey liver. The stability of doxifluridine in liver and intestine of monkey and beagle dog was compared. It was found that bioanalytical validation could not be performed for the monkey liver; however, beagle dog's liver has relatively low speed of metabolism compared to monkey liver and instead of monkey liver, beagle dog's liver could be used for the validation. Bioanalytical validation could be performed in monkey intestine. Eventually, this developed method for liver and intestine will be useful in support of the toxicokinetic and pharmacokinetic studies of doxifluridine and 5-FU.

  • Government duties in the cases of crisis are aimed at supporting efficient military operations in the fields of non-military affairs and resource mobilization, maintenance of government functions, and search for the public security of living during the war. In crisis, the government must change its functions into the total-war system with all resources available for the efficient performance of military operations, war economy, public safety and security as well as government continuance. The main contents of "Chung-Mu Plan" include the alternative measures to control the circulation of life necessities, emergency electricity, water and gas; recover public facilities from the disaster; and accommodate the wounded and refugees. Governments have practiced Ul-chi and ChungMoo exercises to improve government's management capabilities and master standard operating procedures including systematic distribution plans in the national and local level. However, such plans have not yet sufficient enough for the maintenance of public security of living. In addition to the conceptual ambiguity, major problems are the inappropriate system of the war economy, legal institutions, and administrative SOPs for the efficient maintenance of it. Thus, for the betterment of national crisis management system, the government should have the manual stated from every step and level dealing with crisis to the legal institutions. It is important to empower the National Emergency Planning Commission for the policy consistency and efficient/effective implementation. The comprehensive plans must have an integrated cooperative system of the central/local governments, military and civil society with actual practices and exercises for the maintenance of the public security of living.

  • Objectives : Saam acupuncture has evident principles of prescription based on acupuncture tonification and purgation of Nan-gyeong but many prescriptions of Saam acupuncture are not typical patterns. This paper studies principles of prescriptions of the king fire and the premier fire. Methods : Through investigation of many medical documents concerning king fire and the premier fire, the author explained of physiological and pathological principle of king and the premier fire, also explained of interacting mechanism through five element. And The theoretical authorities of analysis are Nan-gyeong, works of Joo dan-gye and Li dong-won. Results & Conclusion : 1. The sufficiency and the control of the water is the key to treat the disease by fire. Considering the attack and the treatment of disease, heart and liver give rise to fire in its early stage and kidney and lung are the key to treatment. 2. Consequently the pathology of the disease from fire is corresponding to the theory- Yang Sufficient, Yin Deficient- of Joo dan-gye. It seems that the theory of Joo dan-gye influenced on the medical theory of Saam Acupuncture. 3. On that account I believe that the study of medical theories of the Geum and Won Dynasty that various medical theories had appeared is very available for Saam Acupuncture. At present global warming is accelerating because environmental pollution has been increasing. Therefore the damage of fire to human body will be more and more severe and extensive. Because in the future medical plants will not be free from environmental pollution, acupuncture will be very confidential treatment.

  • Objectives : To observe the regenerative effects of indirect moxibustion, a traditional Korean medical treatment on skeletal muscles using mouse model of skeletal muscle adiposity. Methods : Twenty seven ICR male mice were randomly assigned into Intact control(n=3), glycerol treatment together without moxibustion(n=12), and glycerol treatment together with moxibustion (n=12) groups. Mice of glycerol treatment groups were injected with 50 ${\mu}l$ DW(distilled water) containing 50 % of glycerol into the two tibialis anterior. After injection, moxibustion was applied at 'Shenshu'($BL_{23}$) and 'Zusanli'($ST_{36}$) acupoints three times per each session, every days for twelve days(total 12 treatments). Phospho-Erk1/2, Myostatin protein levels were analyzed by western blotting and immunofluo-rescence staining techniques for tissues of the tibialis anterior muscle. Smad, phospho-Smad were analyzed by immunofluorescence staining. Results : 1. Histological analysis of sections from injected TA muscles showed that glycerol induced rapidly muscle necrosis, with a maximum at day 3. 6 days and 9 days after injection, muscle was regenerating. 2. According to western blotting and immunofluorescence staining, phospho-Erk1/2 protein signals in glycerol treatment with moxibustion group were stronger compared to Intact and glycerol treatment without moxibustion group. 3. According to western blotting and immunofluorescence staining, myostatin protein signals in glycerol treatment without moxibustion group were stronger compared to Intact and glycerol treatment with moxibustion group. 4. According to immunofluorescence staining, Smad protein signals in glycerol treatment without moxibustion group were stronger compared to Intact and glycerol treatment with moxibustion group. 5. According to immunofluorescence staining, phospho-Smad protein signals in glycerol treatment without moxibustion group were stronger compared to Intact and glycerol treatment with moxibustion group. Conclusions : These results confirm that indirect moxibustion of 'Shenshu'($BL_{23}$) and 'Zusanli'($ST_{36}$) influences muscle regeneration in mouse models of skeletal muscle adiposity. Further discussion, and the establishment of moxibustion mechanism will prompt clinical application of moxibustion.

  • This study tried to develop Siraegi by boiling it down in soy seasoning sauce with excellent sensory attributes and evaluate the quality characteristics in order to enhance the value of traditional agricultural products, dried radish leaves. Sugar content of the seasoning sauce were finally established at 30% (w/v) compared with the starch syrup, which was added to the sauce through sensory evaluation among four groups, 0%, 30%, 60% and 100%. The texture (breaking strength) of Siraegi which was boiled for 30 minutes in water with baking powder was reduced by showing softening effect ranging from 7.6% to 42.1% as the amount of added baking powder was increased. The color of braised Siraegi produced with prepared a seasoning sauce and different content of baking powder, the brightness significantly decreased with an increase of baking powder. The reduction effects of breaking strength ranged from 25.6% to 43.9%, resulting a significant difference. The pH of braised Siraegi with a seasoning sauce significantly increased from 5.71 to 6.04 as the amount of added baking powder was increased, while its acidity was decreased. Sensory evaluation showed significant values for hardness and toughness as the values dropped when compared with the control (p<0.001), and overall acceptability of the group with adding 0.2% baking powder was best (p<0.001). In conclusion, baking powder could be considered as softening agent shorting the cooking time and improvement of the acceptability. Furthermore, it was expected that the newly developed soy sauce barised Siraegi using the dried radish leaves would be successfully utilized by side dishes in the food preparation industry.
