An increasing frequency of methicillin resistant S. aureus(MRSA), methicillin resistant coagulase negative staphylococci(MRCNS) and Enterococcal infection have been observed in recent years. Teicoplanin is a new glycopeptide antibiotic obstained from the Actinoplanes teicomycetius. The molecular structure and spectrum of antimicrobial activity of teicoplanin is simillar to those of vancomycin, and has been reported to have an excellent in vitro and in vivo effect against various gram-positive infections. Therefore, we evaluated the in vitor susceptibility of gram positive cocci, such as, S. aureus, coagulase negative Staphylococci(CNS), and Enterococci to teicoplanin and vancomycin. The total 253 strains consisted of MSSA(40), MRSA(53), MSCNS(47), MRCNS(48), and Enterococci(65). They were assayed by disc diffusion and agar dilution. During the study, 57% of S. aureus and 49% of CNS showed resistance to methicillin. The inhibitory diameter of teicoplanin was 15-20mm in MSSA, 12-19mm in MRSA, 13-24mm in MSCNS, 11-23mm in MRCNS, and 15-22mm in Enterococci respectively, and showed sensitivity in all but 8 strains(3.2%). The range of the minimum inhibitory concentration (MIC) of teicoplanin to MSSA, MRSA, MSCNS, MRCNS and Enterococci were 9.12-2.0㎍/ml, 0.25-2.0㎍/ml, & 0.25-32㎍/ml, 0.12-1.0㎍/ml respectively. One case of S. haemolyticus was resistant to teicoplanin (32㎍/ml) by the agar dilution method. Eight minor (3.2%) and one major(0.4%) error was observed when the MIC and disk diffusion data were correlated with teicoplanin. As for vancomycin the inhibitory diameter was 17-21mm in MSSA, 15-21mm in MRSA, 18-26mm in MSCNS, 18-25mm in MRCNS, and 16-22mm in Enterococci respectively. The range of the MIC of vancomycin to MSSA, MRSA, MSCNS, MRCNS, and Enterococci were 0.25-1.0㎍/ml, 0.25-4.0㎍/ml, 0.5-2.0㎍/ml and 0.5-2.0㎍/ml respectively. One minor error (0.4%) was seen with the vancomycin disk. The MIC90 of MSSA and MRSA exhibited the same results in teicoplanin (1.0㎍/ml, 1.0㎍/ml), and vancomycin(2.0㎍/ml, 2.0㎍/ml). MSCNS and MRCNS exhibited greater MIC90 with teicoplanin(4.0㎍/ml, 8.0㎍/ml) than vancomycin(2.0㎍/ml, 2.0㎍/ml). Incontrase Enterococci were more susceptible to teicoplanin(0.5㎍/ml) than to vancomucin (2.0㎍/ml). Results from this analysis indicated that both teicoplanin and vancomycin were very excellent for gram positive infections, especially those resistant to methicillin.

As the computer systems are developed rapidly, the area of the engineering softwares are also expanded. Most of these engineering softwares are the high-priced commercial softwares for the exactness of the results. However, the commercial softwares are too expensive for some users. especially undergraduate students. In this study, the engineering software for the chemical process control is made of the JAVA language in a web environment. Then the virtual experiment of the process control can be executed free of charge using this software. This software is worked on the internet and shows how to identify a unknown process system and how to tune the control parameters to operate the process system. The numerical examples are presented to illustrate the virtual experiment for the process control using the software made in this study.

The purpose of this study was to examined the effect of supervised regulary aerobic exercise program with cardiorespiratory function of obese children. The subjects were 16 obese Childrens(elementary school 4∼5 grade), and engaged in regulary aerobic exercise program for 9 weeks(5 days/week, 100 min/day, 60∼70% HRmax) with mountain climbing, basketball and football. The items of cardiorespiratory function measured VEmax, HRmax, RQmax, VCO₂max, VCO₂max, VCO₂max/kg and BFmax after treadmill exercise load. The conclusion of this study was as follows ; 1. In body composition, there were significant decrease(P<0.001) after aerobic exercise for 9 weeks in body weight, percent body mass index 2. In cardiorespiratory function, there were significant increase(P<0.001) after aerobic exercise for 9 weeks in VEmax and VCO₂max by treadmill exercise load. 3. In cardiorespiratory function, there were significant increase(P<0.001) after aerobic exercise for 9 weeks in VO₂mex and RQmax by treadmill exercise load. 4.

Atherosclerosis, along with the resultant coronary artery disease (CAD), is a leading cause of mortality in industrialized countries. Lipoproteins (LP) are generally classified according to their density. Triglycerides are mainly transported in chylomicrons and very low density LP (VLDL), cholesterol is mainly transported in low density LP (LDL) and high density LP (HDL). The metabolism of LP is controlled by their apolipoproteins, by specific receptors, enzymes, and transfer proteins. Lipoprotein receptors are membrane proteins which play a central role in lipid metabolism. The low density lipoprotein (LDL) receptor recognises lipoproteins containing apolipoprotein B100 or an activated form of apo E. The LDL receptor therefore mediates the uptake of intermediate density lipoprotein (IDL) and LDL by the liver, and it also facilitates uptake of LDL by other tissues. Cellular cholesterol efflux is mediated by HDL, acting in conjunction with the cholesterol esterifying enzyme, lecithin: cholesterol acyltransferase (LCAT). Cholesterol ester accumulating in HDL can then follow a number of different fates: uptake in the liver in HDL containing apolipoprotein (particle uptake) by LDL receptors, selective uptake of HDL cholesterol ester in liver or other tissues involving scavenger receptor B1 (SRBI), or transfer to triglyceride-rich lipoproteins as a result of the activity of cholesterol ester transfer protein (CETP), with subsequent uptake of triglyceride-rich lipoprotein remnants in the liver. CETP promotes the transfer of cholesterol esters (CE) from antiatherogenic HDLs to proatherogenic apolipoprotein B (apoB)-containing lipoproteins, including VLDLs, VLDL remnants, IDLs, and LDLs. A deficiency of CETP is associated with increased HDL levels and decreased LDL levels, a profile that is typically antiatherogenic. Recently, another key molecule involved in this pathway was identified, scavenger receptor BI ; this mediates the selective uptake of HDL cholesterol esters in the liver and thus constitutes a pathway of reverse cholesterol transport parallel to that mediated by CETP. Thus, the remodeling of human HDL by CETP, involving CE;-TG interchange, followed by the action of hepatic lipase (HL), leads to the enhanced uptake of HDL CE by cellular SR-BI. These observations suggest that in animals such as humans in which both the selective uptake and CETP pathways are active, the two pathways could operate in a synergistic fashion to enhance reverse cholesterol transport. In conclusion, a major challenge will be to determine if manipulation of RCT pathway by targeting molecules such CEPT, LCAT, HL, or SRBI can be used for therapeutic benefit.

Recently, social agreement on the environment pollution has gradually increased in the national and global scope. Also in the last one decades fast industrialism in China has caused to the nations concerns and anxiety on the environmental problems of the North-East Asia including Japan. Korea located mostly close to China has been effected directly on the pollutant products produced from China and many environmental co-work problems of both nations has become to delayed objects anymore. The purpose of this study is to investigate cases and problems of the national overflowing environment pollution and describe answerings.

The purpose of this study was to evaluate the effect of aerobic exercise in body composition, physical fitness and cardiorespiratory function in middle-aged women. The subjects were included 2 groups: Exercise group in which women exercised for over 1 year; Non-Exercise group. The values of measurement were body weight, body density, body fat, standing trunk flexion, vertical jump, burpee test, hanging on horizontal bar, Vo₂max, ??, RRmax, T-cholesterol, HDL-cholesterol and Triglyceride. 1) No Significant differences were found between exercise group and non-exercise group on body weight, body density. But Significant differences were found on body fat(P<0.01) and lean body mass(P<0.05). 2) Significant differences were found between exercise group and non-exercise group on standing trunk flexion and vertical jump(P<0.01). 3) Exercise groups significantly marked high Vo₂max values when comparing with non-exercise group(P<0.01). And significant differences were found between exercise group and non-exercise group on ?? and RRmax(P<0.01). 4) No significant differences were found between exercise group and non-exercise group on T-cholesterol, TG, T-chol./HDL-chol.. But there was significant difference of HDL-cholesterol between exercise group and non-exercise group(P<0.01).
