In this paper, we consider a rule of application of PRICE(Parametric Review of Information for Costing and Evaluation) model to the environment of Korean defense industry. The PRICE model which is a computer model to estimate the cost of an acquisition program, was developed for the regulation of defense acquisition program in the United States. Therefore, it is essential for us to figure out how we can adopt it under our defense acquisition regulations. We will give an alternative method to apply the PRICE model to the mapping problem between two regulations.

J sewage treatment plant (WWTP) in Busan has used methanol as an external carbon source for the biological denitrification process. Methanol is widely used. but rather expensive and very dangerous in handling. Therefore, it has been required that the economic alternative carbon source must be developed. By-product from a fine chemical industry can be Purified by removing high molecular weight substances using the ultrafilter membrane separation process and RBDCOD fraction becomes $98{\sim}99%$ of COD substances in the purified by-product. The purified by-product containing three types of alcohols, methanol, prophylenglycol and methoxypropanol; showed similar chemical characteristics to the methanol, a main external carbon source, in biodegradation pathway. Shown above, the compatibility between main and alternative carbon sources has been achieved. Also very short or no adaptation period is necessary in the case of exchanging these carbon sources. The compatibility between external carbon sources is an essential element for stabilizing WWTP operations. During the full-scale application test of the by-product, the alternative carbon source line got on par with the treatment efficiency of the methanol line. With the test result, J-WWTP changed methanol to a fine chemical by-product, in two out of three J-WWTP lines. Moreover, it is expected that 55.4% of the external carbon source cost reduction can be achieved in the alternative carbon source applied lines.

Recently, Gonzalez-Audicana et al. proposed the substitute wavelet intensity (SWI) method which provided a solution based on the intensity-hue-saturation (IHS) method for the fusing of panchromatic (PAN) and multispectral (MS) images. Although the spectral quality of the fused MS images is enhanced, this method is not efficient enough to quickly merge massive volumes of data from satellite. To overcome this problem, we introduce a new SWI method based on a fast IHS transform to implement efficiently as an alternative procedure. In addition, we show that the method is well applicable for fusing IKONOS PAN with MS images.

In our country, patients with diabetes mellitus are searching for complementary treatments to recover from illness, while they received treatments from the doctor. However, have been evaluated or investigated systematically. This study was carried out to explore application of complementary treatments for patients with DM. For this survey, questionnaires were developed by researchers and the data was collected from July to October of 1999. Among the 223 subjects, there is one general hospital, one oriental hospital, 15 area C.H.P, ahd 2 area health centers. The results were as follows: 1. The total number of cases was 223 and the average age was 62.85 years old and average duration of DM was 8.1 years. The number of patients who had experience with alternative therapies was 145 (65%). The number of those who have not undergone treatments was 78 (35%). 2. The 43.5% of experienced CAM were advised family and relatives. Only 30.3% approved the effect of CAM and 52.5% said that If another a new CAM is introduced, they will try it. 4. Ninety three kinds of complementary treatments were used. Among the used items, 63.7% was various types of plants, 21.6% was animal material and 14.7% was the mixed group. As a single item, Bombyx Mori (Silkworm) was the most frequently used (10.5%) followed by the bean, mushroom, Morus bombycis (mulberry), Ginseng, Commelina Communis (Dalgaebi), Chinese medicine, root of Rosa rugosa (Haedangwha). 5. Among the used items, Trichosanthes kirilowii Max. Eucommia ulmoides Oliver, Commelina Communis, Aralia elata, pine needle, mulberry fruit, root of Rosa rugosa. Ginseng, Lycii Fructus, Dioscorea radix, Polygonatum odoratum, Cassia tora L, Bombyx Mori, loach, Crucian carp were based upon the pharmacological function of effect for control of diabetes mellitus symptom. 6. In the analysis of the relationships between the general characters of the patients with new complementary alternative medicine try and hospital treatment; 1) The shorter group suffered from DM (p=.038), poor Self-MBG (p=.037) and wanted to try new complementary alternative medicine. 2) The group of DM education experience were carried out hospital treatment well (p=.045). In conclusion, further study will be required for the patients experience using alternative therapies as the D-M in terms of holistic view of patients.

Objectives : The aim of this study was to investigative the effects of Gagambojungikgi-tang (GBT), a Korean herbal medicine, on the immune mediators, T cell proliferation and wound healing in the recombinant Sj26 (rSj26) antigen induced atopic dermatitis(AD) model mice. Methods : GBT is the water extracts prepared from mixture of Ginseng Radix, Astragali Radix, Angelicae gigantis Radix, Atractylodes Rhizoma alba, Aurantii nobilis Pericarpium, Glycyrrhizae Radix, Artemisia iwayomogi Herba, Scutellaria Radix, Lonicera japonica Flos. This is a modified prescription of Bojungikgi-tang, which has been used for the treatment of indigestion, and immunological disease in east-asian countries. GBT was orally administered or externally applied at difference doses. The levels of immune mediators [(IgE, IgG1, prostaglandin E2 (PGE2), Th1/Th2 cytokines], T cell proliferation, and wound healing in the rSj26 or chemical antigen induced AD model BALB/c were investigated. Results : GBT dose-dependently suppressed the release of TNF-${\alpha}$, IL-$1{\beta}$ (Th1 cytokines), IL-4, IL-10 (Th2 cytokines), PGE2 (inflammatory mediators) and T cell proliferation. But GBT increased the production of IFN-${\gamma}$ (Th1 cytokine). Furthermore, A wound healing effect of GBT was similar to external application of dexamethasone. Conclusions : These results suggest that GBT suppresses the inflammatory mediators and regulates the Thl/Th2 cytokines, and promotes the wound healing. Therefore, these properties may contribute to the strong anti-AD effect of GBT.

Purpose Retrofit, defined to be addition of new technologies or features to the old system to increase efficiency or to abate GHG emissions, is considered as an important alternative for the old coal-fired power plant. The purpose of this study is to propose mathematical method to model multiple alternative retrofit in Generation Capacity Expansion Planning(GCEP) problem, and to get insight to the retrofit patterns from realistic case studies. Design/methodology/approach This study made a multi-alternative retrofit GECP model by adopting some new variables and equations to the existing GECP model. Added variables and equations are to ensure the retrofit feature that the life time of retrofitted plant is the remaining life time of the old power plant. We formulated such that multiple retrofit alternatives are simultaneously compared and the best retrofit alternative can be selected. And we found that old approach to model retrofit has a problem that old plant with long remaining life time is retrofitted earlier than the one with short remaining life time, fixed the problem by some constraints with some binary variables. Therefore, the proposed model is formulated into a mixed binary programming problem, and coded and run using the GAMS/cplex. Findings According to the empirical analysis result, we found that approach to model the multiple alternative retrofit proposed in this study is comparing simultaneously multiple retrofit alternatives and select the best retrofit satisfying the retrofit features related to the life time. And we found that retrofit order problem is cleared. In addition, the model is expected to be very useful in evaluating and developing the national policies concerning coal-fired power plant retrofit.

The purpose of this study is to predict the degree of taking the complementary & alternative therapy in the home care nursing service and provide basic data for the application of it. To accomplish this, degree of general recognition of the complementary & alternative therapy, experiences, degree of concern, applicability of the therapy, and educational need should be studied. This study is a descriptive research survey on the home care nurses working at 73 medical centers out of 125 nationwide who provide hospital based home nursing care. The data was collected from Sep. 20, to Oct. 20, 2004 by ChoiHeyran's questionaries (2002). The data was analyzed by the frequency and the percentage. The results of this study are as follows ; 1. The degree of pre-cognition on the complementary & alternative therapy is very high. Information about the therapy was mostly obtained through medias. Home care nurses understand that he desirable treatment is to practice medical treatment and complementary & alternative therapy simultaneously. While 50% of them have already practiced complementary & alternative therapy among their patients. The most commonly used therapy is Acupressure. And Home care nurses have open and positive attitudes about the complementary & alternative therapy as to answer they aye ready to recommend it to their patients. 2. Over half of the Home care nurses met patients taking complementary & alternative therapy. 94.5% of them think scientific diagnosis on the effect of the therapy. advice from the doctor. and the special working staff is required to apply it on to the home care nursing. 3. 68.5% of the Home care nurses have taken education on the therapy through general comprehensive instructions and supplementary. Most of them want to have a opportunity education on the therapy because they want to provide comprehensive nursing and diversified nursing service. The preferred educations are Hand acupuncture, Acupressure & Massage and Aromatherapy, in that order. Based on the above results, the followings are recommended. 1. A study that stipulates the types, applications, and efficiency assessment of the complementary & alternative therapy practiced by Home care nurses in the home care nursing care procedure.
