In this research a model for establishing a new, rational fee schedule for general surgical procedures in a national health insurance program is developed. A fuzzy multiple criteria decision-making (FMCDM) model is proposed. The relative values of eleven surgical procedures were obtained through an empirical study based on the FMCDM model. Consequently, a new fee schedule obtained from the FMCDM model. This new fee schedule is more convincing than previous schedule and more persuasive to the references for the policy setting.

The present study investigated the use of cow faeces as a source of micro-organisms instead of sheep rumen liquor in in vitro digestibility assays of forages. Initially 40 forage samples comprising ryegrass, wheat, maize and barley were screened to select a wide range of digestibility (327-794 g/kg) of forages. Finally 8 forage samples were assessed using rumen liquor as well as faecal liquor. The absolute organic matter digestibility (OMD) values using faecal liquor were lower than those with rumen liquor. However, the relationship between OMD using rumen liquor and faecal liquor was highly significant (p < 0.001). The $R^2$ value exceed 0.90. The results suggest that micro-organisms from faecal liquor are capable of digesting forage samples.

We study the conditional integral transforms and conditional convolutions of functionals defined on K[0, T]. We consider a general vector-valued conditioning functions $X_k(x)=({\gamma}_1(x),{\ldots},{\gamma}_k(x))$ where ${\gamma}_j(x)$ are Gaussian random variables on the Wiener space which need not depend upon the values of x at only finitely many points in (0, T]. We then obtain several relationships and formulas for the conditioning functions that exist among conditional integral transform, conditional convolution and first variation of functionals in $E_{\sigma}$.

2-Arylthio-, 2-arylthio-5-methoxy-, 2, 3-bisarylthio-juglones and 2, 3-bisarylthio-5, 8-dimethoxy-1, 4-naphthoquinones were newly systhesized for the evaluation of antifungal activities. These derivatives were prepared by methylation of juglone and 2, 3-dichloro-5, 8-dihydroxy-1, 4-naphthoquinone. and by resioselective nucleophilic subsitution with arylthiols. All compounds were tested in vitro for their growth inhibitory activities against pathogenic fungi by the standard method. The MIC values were determined by comparison to flucytosine as a fungicidal standard agent. In general. In general. most juglone derivatives shows in vitro antifungal activities. Among them. 2-arylthio-5-methoxy-juglones showed most potent antifungal activities against all pathogenic fungi.

The dynamic characteristics such as natural frequency, mode shape and damping ratio are most important parameters in the high-speed railway bridges rather than general roadway bridges. Also, the need to know the dynamic behavior of bridges greatly increased in recent years. In the early of 1990s, to design the high-speed railway bridges, damping ratio recommended in general code was 2.5~7.5%. However, these values were not applied in all cases. Therefore, obtaining the damping value of specific structures is important to get the correct variable for design of high-speed railway bridges. The purpose of this study is mainly to obtain the damping ratio of high-speed railway bridges. The average damping ratio of high-speed railway bridges evaluated from a field test is about 2.4%.

In this study the characteristics of adiabatic and lightweight of cement mortar was improved by using porous Bottom ash which was industrial waste. when a foaming agent was added, the characteristics of mortar using sand and Bottom ash were compared. From the empirical results the heat-transfer ratio for the mortar using Bottom ash only was shown the lower values than that for a general mortar, and the lightweight concrete with unit weight of 1.5t/$\textrm{m}^3$ could be made. When the foaming agent of 0.25% and 0.5% in usage of cement was added to that, the compressive strength scould be measured as 5 and 8times of the general mortar respectively. Also, the characteristics of adiabatic for that mortar was great improved so that the heat-transfer ratio was fallen to 0.172kcal/$mh^{\circ}C$.

The A.M.I(acute myocardiac Infarction) treated in Rehabilitation programs May be divided Into three general types, 1. mechanlcal derangement. 2. Increased resistance to blood flow. 3. decreased Energy production. in each case the heart Will be Limited in its ability to respond. to the demands of metabolic activites. cardiac rehabilitation programs following myocardiac infarction are of two general types:acute and delayed. There are fundamental differences in the philosophies, pathophilogical concepts, and psycosocial values in the two approach. both programs asplre to protect the patient through the period of Maximal risk and then safely restore him to a near normal home life and appropriate vocatlonal activity. Both programs assume that physical activity and emotional stress. increase the work of the heart and with it increase the likefood of venticular fibillation

The purposes of this article are to analyze the conditions of using instructional strategies and using gender sensitive instructional strategies at engineering classes of K University. Qualitative analysis methods were adapted. To achieve the purposes, 35 hours of engineering classes from 11 professors from 9th to 20th of November 2009 were videotaped and analyzed. The research findings were discussed by the checklists for general and gender sensitive the instructional strategies which were recommended for the managing the better classes. Students are influenced by professors not only knowledge and skills but also values and attitudes. Professors who take gender sensitive instructional strategies are expected to give good influence the women students.

In this regard, urban agriculture is developing into a variety of shapes. Urban agriculture includes various types, such as industrial agriculture, experience agriculture, educational agriculture, exchange agriculture and cyclic agriculture. The result of evaluation on citizens' values about multi-functions provided by urban agriculture can be used for policy making to overcome crisis of urban agriculture due to urban development and industrialization and to vitalize urban agriculture. The willingness-to-pay for the maintenance fund was categorized into vegetable garden users, general consumers, and all respondents, for analysis. The estimation results for the valuation of multi-functionality were KRW 20,367 per household for general consumers; KRW 22,174 for urban agriculture users; and KRW 21,467 for all respondents.

This study analyzed the status and causes for the dropouts of college based on the survey conducted among 14,210 freshmen attending D College, other than the supernumerary special selection, from 2001 through 2005. A significant difference was shown in all items of general characteristics. The dropout rate of women, generally selected and general high school graduated were higher than for men, specially selected and special high school graduated, respectively. The most dropouts were due to Not Return(40.16%), followed by Unenrolled(32.98%), Voluntary Leave(26.05%) and Expelled(0.81%) in order. In the distribution of the central tendency values measured from the entire subjects. the high school records and the days of absence showed a positive skewness. while the college records showed a negative skewness with the data mostly around a higher grade. The standard deviation indicating that the dropouts got the scores higher than those of the continuing students demonstrated that there was relatively insignificant difference in scores between two groups.
