There are increasing demands for the producing and breeding new domestic riding horses for the vitalizations of horse riding industry in Korea, according as 'Horse Industry Support Act' became. In this study, we were to develop the functional relation through the conformation comparison & body composition analysis. 76 heads of 5 breeds utilized for riding horses in Korea were used and their body measurements on 12 items were measured and cluster analysis was conducted to determine the correlation relation among them. The measurements were standardized that (height, croup height, pelvis length), and (hip width, width of pelvis) were highly correlated. In these results of the decision tree, we confirmed to classify the breed type determination by their body measurements (hip height, hip width, head length, croup height). This result can be used as basic data for the development of horse type determination (racing, riding, Riding for the Disabled, Working, or fattening) through the analysis of body composition, and be utilized as the basic data for the producing and breeding new domestic riding horses through the 3D Stereosocpic image system analyze.

This study investigated the influence of IRM on marginal microleakage of 5th generation adhesives. Class V cavities with gingival margins in dentin were prepared on both buccal and lingual surfaces of 60 extract-ed human molar teeth. Prepared teeth were randomly divided into six groups. Group 1 and 4 received no temporary restoration with IRM. Group 2 and 5 were covered with IRM mixed at P/L ratio(10g/1g). Group 3 and 6 were covered with IRM mixed at P/L ratio(10g/2g). The temporary restorations were removed mechanically with an ultrasonic scaler after one-week storage in distilled water. The cavities were restored using one of two adhesives and composites ; Single Bond/Filtek Z 250(Croup 1, 2 and 3), UniFil Bond/UniFil F(Group 4, 5 and 6). Following one day storage in distilled water, the restored teeth were thermocycled for 500 cycles(between $5^{\circ}C{\;}and{\;}55^{\circ}C$) and immersed in 2 % methylene blue for dye penetration testing. The results were analysed using Kruskal-Wallis Test, Mann-Whitney and Wilcoxon signed ranked test at a significance level of 0.05. The results of this study were as follows 1. Ranking of mean microleakage scores at the enamel margins was Group 10.05) 4. At the dentin margins, the microleakage of the group not pretreated with IRM was lower than that of the group pretreated with IRM. And the microleakage of UniFil Bond was lower than that of Single Bond. 5. Compared with microleakages between the enamel and dentin margins of each groups, Group 1, 2, 3, 4, 5 and 6 at dentin margin were higher microleakage than those at enamel margin. There were significant difference between enamel and dentin microleakage of Group 2 and 3(p<0.05).

The metasedimentary rocks of the Nampo Croup consisting of metaconglomerates, metasandstones, phyllites are exposed in the area of the Daechcon beach and Maryangri, Seocheon-gun. Their typical metamorphic assemblages of Bt-Mus-Grt-Qtz (${\pm}Pl{\pm}Chl$) and Bt-Mus-Qtz (${\pm}Pl{\pm}Chl$) indicate that they have been under intermediate P/T type metamorphism and were metamorphosed to garnet zone grade of amphibolite-facies during the Daebo Orogeny. Pressure-temperature conditions of peak metamorphism estimated from geothermobarometries are $560{\sim}595^{\circ}C$, $6.9{\sim}8.2\;kb$ respectively. The results of K-Ar biotite age determination are $143.2{\pm}3.6\;Ma$, $122.6{\pm}2.4\;Ma$ and $124.8{\pm}2.4\;Ma$ and the last two ages are considered as the results of later-stage thermal perturbation. On the bases of the formation age of Daedong Supergroup of $187{\sim}172\;Ma$ (Han et al., 2006; Jeon et al., 2007) combined with the results of this study, the hypothetical model of tectonometamorphic evolution of the study area during Daebo Orogeny is proposed. Crustal thickening resulted from folding and duplexing of thrusts in the area initiated at around 175 Ma just after sedimentation of Nampo Croup. And then rapid cooling by normal faulting due to crustal extention followed immediately after the peak metamorphism to the closure temperature of biotite.

Purpose : We analyzed clinical and radiological results of the treatment of osteochondritis dissecans in the femoral condyle under arthroscopic guidance. Materials and Methods : The study group consists 19 cases in 17 patients. Average follow up period was 34 months and average age was 16 years. The cases were classified by 4 different groups, using the fellowing system: Group 1-stable lesion and no specific treatment after arthroscopic examination; Group 2-early separation and multiple drilling; Croup 3-unstable lesion and Herbert screw fixation; Croup 4-loose body removal and/or crater curettage. The results were analyzed by the criteria of Hughston which including clinical and radiologic outcomes. Results : There were 14 cases$(74\%)$ of good and excellent results in 19 knees in which, $75\%$(3/4) in Group 1, $75\%$(3/4) in Group 2, $86\%$(7/8) in Group 3 and $33\%$(1/3) in Group 4. The result of Herbert screw fixation group was better than that of other groups with statistically significant differences. Conclusion : In the treatment of osteochondritis dissecans of skekletally immature patients, arthroscopic finding was reliable guidance in decision of treatment method and active fixation was recommended in patients with large, unstable lesion.

Purpose : This study was to investigate the prevention of spasticity with modified Ashworth scale(MAS) and range of motion(ROM) increase with goniometer in ankle joint by functional electrical stimulation(FES) and exercise for 4 weeks in chronic stroke patients. Methods : 60 chronic stroke patients participated in this study. The subjects were divided into 3 groups, FES group(n=20), FES+exercise group(n=20) and control croup(n=20). After FES application on tibialis anterior muscle by 35Hz for 4 weeks, the change of ankle joint movement was measured by goniometer. Results : The spasticity in ankle joint was decreased greatly in FES and FES+excercise groups(p<.05), and the ROM of ankle joint was increased greatly in FES and FES +exercise groups(p<.05) than control group(p>.05). Conclusion : It shows that FES made the angle of dorsiflexion in spastic ankle joint increase with functional improvement of tibialis anterior muscle in chronic stroke patients. This show that the FES is avaliable for facilitation of ROM and decrease of spasticity as a therapeutic tool.

Hemolysin (VFH) of V. fluvialis, which is a pathogenic bacteria, causing watery diarrhea with vomiting, abdominal croup, was purified. V. fluvialis was cultivated in BHI medium and the culture supematant was precipitated by ammonium sulfate. The protein was purified by chromatographies on columns of DEAE-cellulose and Mono-Q. Molecular weight of the purified VFH was estimated as 79kDa by SDS-PAGE. The optimal temperature for a maximum hemolytic activity was at around 35$^{\circ}C$ and the activity was decreased at 4$0^{\circ}C$ Cytotoxicity of VFH was also investigated using RTG-2 cell line. LDH assay study showed that 50$\mu\textrm{g}$/m1 of VFH release 80% of total cellular LDH (lactate dehydrogenase) from RTG-2 cell and microscopic observation also showed the morphological change of cell.

The purpose of this research is to identify user needs for community space design, especially shared space. and compare them according to social class. Since the shared space concept is new, it will be difficult for residents to familiarize themselves with the new idea. This study used a Small Croup Workshop Panel Method instead of the conventional survey method for this reason The subjects were 6 Panel groups of S people per each group. Bach of the panels included 3consecutive workshops. The results can be summarised as follows. All the residents wanted various kinds of shared spaces for everyday living and leisure activity While there were generally great similarity regardless of resident's sub characteristics, some founed distintively dissimilar. The residents of 20s pyung apartment wanted day-care center, multi Purpose room for meeting and family events, library, study room, sports facilities, and cultural center in order. The shared spaces that residents of 30s pyung apartment wanted were library. study room. common dining, sports facilities. and cultural center in order. The residents of 50s pyung apartment wanted library, study room. multi purpose room, common storage, sports facilities. and cultural center in order. These findings imply some diverse plans instead of uniform ones are to be deliberately considered, This results can be usefully applied to develop new collective housing for different social class residents.

The most prevailing consumption pattern of chicken was "Buy fresh and cook at home (79.8%)". The frequency of eating chicken dish was about "Twice a month". Total average of degree of Preference is "2.30". It is very much close to "Like (2.0)" rather than "Average (3.0)". The degree of preference of chicken decrease as the age increase. About 30% of the housewives have the experience of buying chicken "Cut-up". But "Whole chicken (79.7%)" was still used mostly for chicken dish at home. As the education background improves or living expense increases, housewives purchase chicken "Cup-up" more frequently. The major criteria in purchasing chicken was "Hygiene (67.4%)""Quality (55.2%), "Expiration date (36.7%)" follows next. The groups of ′Above 50 years′, ′Graduate school′ and ′More than 3 million won′show greater interest about "Health" than any other groups. Major chicken dish at home in Korea was "Chopped hot chicken (70.7%)". "Boiled chicken soup (43.2%) \" and "Ginseng chicken soup (39.3%)" follows next. "Order for delivery (57.4%)" increased rapidly for chicken consumption. Croup of ′20~30 years′ order chickens for delivery more frequently than other groups. But as the age of housewives increases, they cook at home more frequently. The most preferred chicken dish for dining-out were "Fried chicken (69.4%)" and "Spicy chicken (57.4%)". The preference of Korean traditional dish for dining out was decreasing except "Chuncheon chicken rib (14.2%)".2%)".

One of the major goals suggested in distributed system is to improve the performance of the system through the load balancing of whole system. Load balancing among systems improves the rate of processor utilization and reduces the turnaround time of system. In this paper, we design the rule of decision-making and information interchange based on knowledge based mechanism which makes optimal load balancing by sharing the future load state information inferred from past and present information of each nodes. The result of performance evaluation shows that utilization of processors is balanced, the processing time is improved and reliability and availability of systems are enhanced. The proposed mechanism in this paper can be utilized in the design of load balancing algorithm in distributed operating systems.
