  • Recently the web service area provides the efficient integrated environment of the internal and external of corporation and enterprise that wants the introduction of it is increasing. Also the web service develops and the new business model appears, the domestic enterprise environment and e-business environment are changing caused by web service. The web service which provides the similar function increases, most the method which searches the suitable service in demand of the user is more considered seriously. When it needs to choose one among the similar web services, service consumer generally needs quality information of web service. The problem, however, is that the advertised QoS information of a web service is not always trustworthy. A service provider may publish inaccurate QoS information to attract more customers, or the published QoS information may be out of date. Allowing current customers to rate the QoS they receive from a web service, and making these ratings public, can provide new customers with valuable information on how to rank services. This paper suggests the agent-based quality broker architecture which helps to find a service providing the optimum quality that the consumer needs in a position of service consumer. It is able to solve problem which modify quality requirements of the consumer from providing the architecture it selects a web service to consumer dynamically. Namely, the consumer is able to search the service which provides the optimal quality criteria through UDDI browser which is connected in quality broker server. To quality criteria value decision of each service the user intervention is excluded the maximum. In the existing selection architecture, the objective evaluation was difficult in subjective class of service selecting of the consumer. But the proposal architecture is able to secure an objectivity with the quality criteria value decision where the agent monitors binding information in consumer location. Namely, it solves QoS information of service which provider does not provide with QoS information sharing which is caused by with feedback of consumer side agents.

  • As the prevalence of coronay artery disease is increasing, the surgical treatment has been universalized and operative outcome has been improved. We analyzed the short and mid-term results of 292 CABGs performed in Kangdong Sacred Heart Hospital. Material and Method: From June 1994 to December 2001, 292 patients underwent coronary artery bypass grafting. There were 173 men and 119 women and their ages ranged from 39 to 84 years with a mean of $61.8{\pm}9.1$ years. We analyzed the preoperative risk factors, operative procedures and operative outcome. In addition, we analyzed the recurrence of symptoms, long-term mortality and complications via out-patient follow-up for discharged patients. Result: Preoperative clinical diagnoses were unstable angina in 137(46.9%), stable angina in 34(11.6%), acute myocardial infarction in 40(13.7%), non-Q myocardial infarction in 25(8.6%), postinfarction angina in 22(7.5%), cardiogenic shock in 30(10.3%) and PTCA failure in 4(1.4%) patients. Preoperative angiographic diagnoses were three-vessel disease in 157(53.8%), two-vessel disease in 35 (12.0%), one-vessel disease in 11(3.8%) and left main disease in 89(30.5%) patients. We used saphenous veins in 630, internal thoracic arteries in 257, radial arteries in 50, and right gastoepiploic arteries in 2 distal anastomoses. The mean number of distal anastomoses per patient was $3.2{\pm}1.0$ There were 18 concomitant procedures ; valve replacement in 8(2.7%), left main coronary artery angioplasty in 6(2.1%), patch closure of postinfarction ventricular septal defect(PMI-VSD) in 2(0.7%), replacement of ascending aorta in 1(0.3%) and coronary endarterectomy in 1(0.3%) patient. The mean ACC time was $96.6{\pm}35.3 $ minutes and the mean CPB time was $179.2{\pm}94.6$ minutes. Total early mortality was 8.6%, but it was 3.1% in elective operations. The most common cause of early mortality was low cardiac output syndrome in 6(2.1%) patients. The stastistically significant risk factors for early mortality were hypertension, old age($\geq$ 70 years), poor LV function(EF<40%), congestive heart failure, preoperative intraaortic balloon pump, emergency operation and chronic renal failure. The most common complication was arrhythmia in 52(17.8%) patients. The mean follow-up period was $39.0{\pm}27.0$ months. Most patients were free of symptoms during follow-up. Fourteen patients(5.8 %) had recurrent symptoms and 7 patients(2.9%) died during follow-up period. Follow-up coronary angiography was performed in 13 patients with recurrent symptoms and they were managed by surgical and medical treatment according to the coronary angiographic result. Conclusion: The operative and late results of CABG in our hospital, was acceptable. However, There should be more refinement in operative technique and postoperative management to improve the results.

  • Purpose: To evaluate the results from arthroscopic repair versus debridement for full-thickness tears of the upper subscapularis tendon. Materials and Methods: Ninety-nine patient outcomes were evaluated and compared prospectively. Sixty-nine patients with full-thickness tears of the upper subscapularis tendon underwent arthroscopic repair (group I) and thirty patients underwent simple debridement (group II) between May 2003 and October 2007. In all patients, the tear was localized to the superior one third of the upper subscapularis tendon. The results of the treatment were assessed by evaluating the UCLA, ASES, and VAS for pain and internal rotation strength scores before and after the operation. Results: In groups I and II, UCLA, ASES, VAS, and internal rotation muscle power (perfect score = 5) scores were improved after surgery. In comparing group I and group II, the UCLA and VAS scores were not significantly different (p>0.05), while the ASES and internal rotation strength scores were significantly different (p<0.05). Conclusion: The arthroscopic repair of full-thickness tears of the upper subscapularis tendon was a better surgical method than simple debridement.

  • Purpose: Adequate health-related information provided by health professionals may help cancer patients overcome their uncertain situation and manage their healthcare. To provide information effectively, there is a need to understand the content of the patients' essential information. The purpose of this study was to identify recent informational needs of postoperative gastric cancer patients. Materials and Methods: Data were collected from 190 postoperative gastric cancer patients who attended the Stomach Cancer Patients' Day ceremony (18 November 2008) held by the Stomach Cancer Center of Samsung Medical Center with the use of a questionnaire which measured informational needs. A questionnaire with 37 items was comprised of domains of diagnostic tests, cancer therapy, prognosis, follow-up, sexual activity, stomach cancer-related information, and 7 single items. Results: The priorities of informational needs were the domains of prognosis, ways of healthcare during treatment (a single item), follow-up, stomach cancer-related information, cancer therapy, and diagnostic tests (in descending order). Items related to prognosis, diet, and management of their healthcare ranked in the top 10 informational need scores. As age decreased, the degree of informational needs about diagnostic tests, cancer therapy, sexual activity, and stomach cancer-related information increased. Conclusion: We suggest that prognosis-related information based on the accumulated institutional therapeutic outcomes and objective prognosis data should be incorporated in the current education program. Health professionals should provide comprehensible information content to cancer patients and caregivers and encourage patients to participate in their therapy with a more positive attitude.

  • Domestic dominant method in subcontract cost estimate for comprehensive program management is estimation by referencing similar cases or relying on the experience and expertise of the engaged. However, this method is not reliable due to lack of accuracy, making it harder for clients to plan and budget the program. Since budget itself is roughly estimated, it becomes a source of cost rise in the course of management due to design modifications. Therefore, the client and service providers shall calculate more accurate service cost by applying objective and scientific method in order to minimize cost rise and cost related dispute. Traditional cases, in estimating program management cost, took Top-Down approach based on precedents and experience. On the contrary, this study will categorize management structure into phases and activities, issue WBS for each phase to estimated schedule and cost for each code, and take Bottom-UP approach. By taking this approach named ICEP (Integrated Cost Estimate based on Project), Set project typical model will be developed for service cost estimating, calculate cost by applying project-specific factors. Also, by analyzing progress data and allocated management cost to complement them, more efficient construction management will take shape based on program management cost standards which reflect project-specific features.

  • Purpose: To determine clinical results for arthroscopic repair of a full-thickness rotator cuff tear using a suture bridge technique. Materials and Methods: Between November, 2007 and October, 2008, we evaluated 90 cases of arthroscopic middle, large rotator tear cuff repair. The mean follow-up period was 15 months (range, 12-23 months). Forty-three cases had medium-sized tears; 47 cases had large-sized tears. At the preoperative stage and again at last follow-up, functional results were assessed by the KSS, ASES, UCLA and the PVAS (Pain visual analogue score). Results: Pain score improved from 2.56 preoperatively to 0.96 at final follow-up; movement scores improved from 6.94 to 1.70. At. final follow-up, the average UCLA score improved from 17.08 to 31.17 with 31 excellent (34%), 49 good (54%) and 10 poor results (12%). The final UCLA score was 31.47 in the group less than 60 years of age and 30.69 in the group over 61 years of age (p=0.344). The UCLA score was 31.23 in those with medium-sized tears and 31.11 in those with large-sized tears (p=0.924). The UCLA score was 31.10 in non-trauma patients and 31.23 in trauma patients (p=0.929). Conclusion: Arthroscopic repair of a full-thickness rotator cuff tear using a suture bridge technique can produce excellent clinical results. These outcomes are not affected by age or trauma history.

  • Purpose : Adolescent/Adult Sensory Profile is the questionnaire to evaluate sensory processing based on daily activities. Self-questionnaire commonly tends to be biased to the characteristics of subject, so its validity is low. This study aims to analyze correlation between questions of Adolescent/Adult Sensory Profile and tactile threshold measured from cognitive behavioral experiment. Methods : The tactile threshold was calculated by tactile detection task and tactile stimuli were provided with the consistent current stimulator. The tactile threshold was compared with results of tactile processing items in Adolescent/Adult Sensory Profile and statistical correlation analysis was performed. Results : Scores in Low Registration and Sensation Seeking had positive correlation with the tactile threshold and scores in Sensory Sensitivity and Sensation Avoiding had negative correlation with the tactile threshold. Among them, only Low Registration was statistically significant. Conclusion : The questions in Low Registration(Tactile Processing)are highly correlated with physiological characteristics. As a result, it was shown that sensory inflow is less, if the tactile threshold is high.

  • When the water quality modelling is done with a manual calibration, it is possible that the researcher's opinion may affect the objectivity of the research. Hence, the role of the automatic calibration is highly important. This research applies a technique to automatically calibrate the water quality parameters by implementing an optimization method. This involves estimating the optimum water quality parameters targeting influential parameters towards the lake's BOD, DO, Phosphorus, Nitrogen and Phytoplankton. To accurately calculate the water temperature and hydraulic characteristics of a deep, stratifying lake, EFDC, a 3-dimensional hydraulic model which can be linked to the WASP7 was applied. With EFDC, the segment of the lake is formed and utilized as an input data of the WASP7. For the calibration of the water quality parameters of the WASP7, an influence coefficient algorithm and a genetic algorithm was applied. Of the five water quality variables for calibration, the normalized residuals of the observed and calculated values of DO, TN, CBOD were relatively small and the three water quality variables were calibrated properly. Yet the accuracy of the calibration of TP and Chl-a was relatively low.

  • The purpose of this research investigates the determinant factors of the joint technology development project performance between SMEs and universities. Reviewing existing papers we could categorize independent variables into three groups of partner characteristics, process management variables and relationship characteristics between partners. Three measures of satisfaction with the cooperation result, the intention of continuing relationship and the utilization of developed technology and product were used as dependent variable considering that we studied the joint projects of SMEs' involvement, short period and small scale. The data was collected by questionnaire survey mailed to the 1082 SMEs and university professors which executed the joint projects sponsored by Small Business Administration in 2009. We received 200 responses from SMEs, and 305 cases from professors among which 55 responses of each partner were on the same project. We analyzed the data sets individually, data of SMEs and that of universities with multiple regression analysis technique and also analyzed the common responses of 55 projects. Analysis results of the data from SMEs indicated that partners' expertise, facilities and equipment, communications, strategic importance, and trust were significant variables for the project performance. Analysis results of the data from universities showed that previous links, definition of objectives, strategic importance, trust and commitment were significant variables. Analysis results of combined data of 55 projects from SMEs and universities indicated that facilities and equipment, project management proficiency and commitment were significant variables.
