Purpose: This study presents clinical results of anterior cruciate ligament(ACL) augmentation using autogenous two-strand semitendinosus tendon in the treatment of partial ACL tears with preservation of residual portion. Materials and Methods: From January 2004 to June 2006, twenty two patients who had an ACL injury underwent ACL augmentation using autogenous two-strand semitendinosus tendon were enrolled in this study. We evaluated the clinical results with regard to clinical findings(range of motion, Lachman test, pivot shift test), standard knee scales(Lysholm, Modified Feagin Scoring System), and KT-1000 arthrometer testing. Results: At minimum one year postoperatively, there was no limitation of range of motion. Lachman and pivot shift tests were negative in all knees. On instrumented anterior laxity test by KT-1000 arthrometer, mean side to side difference was improved from 4.6mm preoperatively to 1.7mm postoperatively. Average Lysholm score was improved from 70 to 92. Ninety one percent of cases were rated as good or excellent in Modified Feagin Scoring System. Conclusion: Augmentation using autogenous two-strand semitendinosus tendon with preservation of residual portion of the ACL seems to be an acceptable method for restoring knee stability and proprioceptive function.

Although various models have been developed to establish the enterprise credit scoring, no model has utilized the enterprise human resource so far. The purpose of this study was to build an enterprise credit scoring model using enterprise human resource factors. The data to measure the enterprise credit score were made by the first-year research material of HCCP was used to investigate the enterprise human resource and 2004 Credit Rating Score generated from KIS-Credit Scoring Model. The independent variables were chosen among questionnaires of HCCP based on Mclagan(1989)'s HR wheel model, and the credit score of Korean Information Service was used for the dependent variables. The statistical method used for data analysis was logistic regression. As a result of constructing a model, 22 variables were selected. To see these specifically by each large area, 6 variables in human resource development(HRD) area, 15 in human resource management(HRM) area, and 1 in the other area were chosen. As a consequence of 10 fold cross validation, misclassification rate and G-mean were 30.81 and 68.27 respectively. Decile having the highest response rate was bigger than the one having the lowest response rate by 6.08 times, and had a tendency to decrease. Therefore, the result of study showed that the proposed model was appropriate to measure enterprise credit score using enterprise human resource variables.

Objective: The objective of this study was to compare the quality of life (QOL) of patients with end-stage renal disease (ESRD) between patients receiving hemodialysis (HD) and patients receiving continuous ambulatory peritoneal dialysis (CAPD) and to compare personal characteristic factors relating to the quality of life in patients with ESRD. Method: This study used a descriptive research design. The sample was recruited using purposive sampling that included 76 ESRD patients receiving either HD or CAPD at a dialysis clinic in Phraphutthabat Hospital, Saraburi Province, Thailand. Data was collected using the Quality of Life Questionnaire for Chronic Kidney Disease ($KDQOL-SF^{TM}$) version 1.3. Independent t-test and ANOVA procedures were used to analyze study data. Results: The results revealed that the HD patients had a moderate level of QOL. The highest scoring dimension of QOL was the encouragement of staff at the dialysis unit and patient satisfaction with the treatment (${\bar{X}}=100$, SD=.00), followed by social support (${\bar{X}}=89.29$, SD =16.88) and cognitive function (${\bar{X}}=88.57$, SD=11.82). On the other hand, the lowest scoring QOL dimension was physical problems (${\bar{X}}=50$, SD=51.89), and pain (${\bar{X}}=50$, SD=39.03), followed by work status (${\bar{X}}=53.57$, SD=45.84) and burden from kidney disease (${\bar{X}}=58.48$, SD=31.07). The CAPD patients also had a moderate QOL. The highest scoring QOL dimension was the encouragement of staff in the renal unit and patient satisfaction with the treatment (${\bar{X}}=100$, SD=.00), followed by social support (${\bar{X}}=95.61$, SD=14.20) and cognitive function (${\bar{X}}=88.83$, SD=13.52). The worst scoring QOL dimensions were work status (${\bar{X}}=44.44$, SD=42.72), general health (${\bar{X}}=53.61$, SD=39.05), and pain (${\bar{X}}=62.70$, SD=41.14). The difference overall and in each dimension of QOL in ESRD patients who were treated with HD and CAPD was not statistically significantly different. The QOL was not significantly different among patients with different personal characteristics except for income and duration of treatment; in those cases, the difference in QOL was statistically significant (p=.05). Conclusion: The overall QOL and life expectancy of patients with ESRD treated with HD and CAPD are not affected by gender, age, marital status, education, occupation, or type of health coverage. QOL was not significantly different, except for patients with different incomes and duration of renal replacement therapy, whose QOL was significantly different. The QOL of patients receiving dialysis should be studied to develop a QOL program for patients with chronic kidney disease who receive dialysis.

This study proposes a novel video traffic flow detection method based on machine vision technology. The three-frame difference method, which is one kind of a motion evaluation method, is used to establish initial background image, and then a statistical scoring strategy is chosen to update background image in real time. Finally, the background difference method is used for detecting the moving objects. Meanwhile, a simple but effective shadow elimination method is introduced to improve the accuracy of the detection for moving objects. Furthermore, the study also proposes a vehicle matching and tracking strategy by combining characteristics, such as vehicle's location information, color information and fractal dimension information. Experimental results show that this detection method could quickly and effectively detect various traffic flow parameters, laying a solid foundation for enhancing the degree of automation for traffic management.

Ansim Flat DATA Plan is a DATA additional service product related to DATA call in a mobile telephone company A. Up to now, the company A is selling it by outbound TM after targeting customers which used data within specific price band. In this paper, we propose a targeting method applying score model combining response rate and retention rate by data mining. The suggested target model is to find customers more likely not only to respond to outbound TM but also to retain Ansim Flat DATA Plan. The proposed targeting method is expected to improve both from 23.7% to 38.8% in the response rate and from 53.2% to 61.4% in the retention rate.

While the method of prioritization has been practicing in the community needs-based programs to improve the effectiveness and efficiency of community health planning, it has not been systematically used. This study aims to suggest more sophisticated method of prioritizing. Based on the analysis of 81 community health plans which adopt prioritizing method, this study tried to examine their methods and criteria and evaluate their adequacy. In the prioritization process, projects themselves, rather than health problems, were commonly adopted for the subject of the analysis. The most used was the Basic priority rating, followed by the Prioritization matrix. Looking at the size of health problem among the prioritization criteria, the prevalence for chronic diseases and the proportion of people with health problems for health behaviors, mainly were used as indicators. Along with the size of health problem, other factors such as the degree of seriousness of health problem, and the effectiveness of intervention have been used as the criteria of prioritizing, not fully supported by objective data base and the clear standard of scoring. In the prioritization, the analysis need to be limited only to health problems, and the scoring criteria for each health problem area be presented.

This study was carried out to estimate the range of the hip score with 3 radiographic evaluation techniques and to identify the relationship among these methods in 71 Sapsarees (35 males and 36 females). Mean age of dogs was ranged from 4 to 73 months (averaged $24{\pm}18$ months). Hip joints were evaluated with OFA method, BVA/KC scoring scheme, and $PennHIP^{(R)}$ method. Hip joints were graded by the OFA grading system(only used for dogs over 24 month old age). The 64 joints evaluated were graded as good (17.2%), fair (46.9%), mild dysplastic (12.5%), moderate dysplastic (7.8%), and severe dysplastic (15.6%), respectively. In BVA/KC scoring scheme, the mean score of the 86 joints was recorded as $14.5{\pm}12.8$ (range from 2 to 52). The mean of Norberg angle in the 78 joints was $92.5{\pm}8.5$ degree (ranged from 63 to 110.5 degree). In $PennHIP^{(R)}$ method on the 126 joints, the mean DI was resulted as $0.60{\pm}0.16$ (ranged from 0.08 to 1.0). BVA/KC scores were gradually increased with age, positively correlated with OFA grade (r = 0.92, P < 0.001), but inversely proportional to Norberg angle (r = -0.79, P < 0.001). However, there was no correlation between BVA/KC and DI (r = 0.11). It was suggested that Sapsarees have high prevalence of cannine hip dysplasia, so selective breeding among sapsarees having normal hip joints might be necessary for preventing or controlling hip dysplasia.

This paper proposes a new confidence measure for utterance verification with posterior probability approximation. The proposed method approximates probabilistic likelihoods by using Viterbi search characteristics and a clustered phoneme confusion matrix. Our measure consists of the weighted linear combination of acoustic and phonetic confidence scores. The proposed algorithm shows better performance even with the reduced computational complexity than those utilizing conventional confidence measures.
