In an effort to facilitate fabrication procedure of all ceramic crowns, a novel preparation method for all ceramic crown using alumina tape was developed. The alumina tape having a uniform thickness was cast by using Doctor blade method. The physical properties of newly introduced alumina tape has biaxial flexure strength of $500\sim600MPa$. The value of toughness is $3.18\sim3,28MPa.m^{1/2}$ which corelates with fracture and the linear shrinkage rate of the alumina tape is 0.44% during core production. The marginal fitness of the alumina tape all-ceramic restoration with $90{!`}$shoulder margin had average marginal discrepancy at $78.3{\S}$ > and average marginal gap at $44.4{\S}$ >. At the marginal preparation of $135{!`}$deep chamfer, the average marginal discrepancy at $82.1{\S}$ > and the average marginal gap at $40.2{\S}$ > had been reported. This fabrication procedure of all ceramic crowns with alumina tapes is easier and less technical sensitive for dental technicians. After restoration with new all ceramic crowns we followed the patients 2 years later, there were no complications as porcelain fractures or periodontal disease. We had good esthetic clinical results with new all ceramic crowns.

Prostate images have been used in the diagnosis of prostate using TRUS images being relatively cheap. Ultrasound images are recorded with 3 dimension and one diagnostic exam is made with a number of the images. A doctor can see 2 dimensional images on the monitor sequentially and 3 dimensional ones to diagnose a disease. To display the images, 2-d images are used with raw 2-d ones, but 3-d images need to be segmented by the prostates and their backgrounds to be seen from different angles and with cut images of inner side. Especially on detecting the boundary, the ones in the middle of all images are easy to find the boundary but the base and apex of the images are hard to do it since there are lots of uncertain boundary. So, in this paper we propose the method that applies an average shape model and detects the boundary, and shows its superiority compared to the existing methods with experiments.

Objective : This study aimed to compare the patients' satisfactions with local Korean Medicine(KM) clinics and networked KM clinics, and to find out which factors had an effect on it. Method : Six local KM clinics and six networked KM clinics were selected, and patients' questionnaires on the satisfaction with KM clinic use were administered using exit poll method. The questionnaires were developed to measure satisfactions with facility, doctor and staffs, and services. 240 patients completed the questionnaires, and the data were statistically analyzed. Results : There was more diversity in patients' diseases among networked KM clinics users, however, treatments provided were not differentiated clinically between two types of KM clinics. Patients' satisfaction scores for local KM clinics were significantly higher than those for networked KM clinics in the aspects of doctors/staffs (9.35 vs 8.92, p<.01) and services (8.76 vs 8.42, p<.05). 90.0% of local KM clinic users expressed their willingness to recommend the clinics they used to others, while 75.0% of networked KM clinics users did. For both the local and networked clinics, 'KM doctors' kindness', and 'process and waiting time' were statistical factors affecting patients' satisfaction. Conclusion : The patients' satisfactions with general KM clinics were higher than those with networked KM clinics. Networked KM clinics need to develop services to meet the diverse medical demands which were created by them selves.

Total hip arthroplasty(THA) considerably depends on high-experienced doctors because of high difficulty of the operation. Selection of acetabular cup's and femoral implant's position is closely related with success or failure of THA. Nevertheless the selection has usually depended on doctor's eye measurement, which makes the position accuracy of artificial joint lower after THA, often resulting in revision of THA. The present study determined a method to select accurately the position of acetabular cup and femoral implant through surgical simulation with 3D characteristic geometrical information of patient's pelvis and femur. We examined the change of femoral anteversion angle and neck-shaft angle accompanied by the change of acetabular cup's position and the insertion position of femoral implant. As result of analyzing geometrical information through different surgical simulations, we found that it was possible to select the accurate position of acetabular cup and femoral implant. It is expected to help doctors get experienced in THA operation through repetitive surgical simulations using the method suggested in the study.

A distributed healthcare monitoring system prototype for clinical and trauma patients, was developed, using wireless sensor network node. The proposed system aimed to measure various vital physiological health parameters like ECG and body temperature of patients and elderly persons and transfer his/ her health status wirelessly in Ad-hoc network, to remote base station which was connected to doctor's PDA/PC or to a hospital's main Server using wireless sensor node. The system also aims to save the cost of healthcare facility for patients and the operating power of the system because sensor network is deployed widely and the distance from sensor to base station was shorter than in general centralized system. The wireless data communication will follow IEEE 802.15.4 frequency communication with ad-hoc routing thus enabling every motes attached to patients, to form a wireless data network to send data to base-station, providing mobility and convenience to the users in home environment.

Objectives: This study aims to examine hypertension patients' quality of life by using the data of the 7^th Korea National Health and Nutrition Examination Survey (1^st year, 2016), identify the factors related to this, and utilize the results as basic data for intervention that can improve hypertension patients' quality of life. Methods: For the research subjects, this study extracted 1,531 patients who were diagnosed with hypertension by a doctor from the total sample of 8,150 participants of the 7^th Korea National Health and Nutrition Examination Survey, and selected 1,072 patients with no missing value in the variables to be analyzed as the final research subjects. The SPSS(version25.0) program was used for the analysis of the collected data. Then, this study used a backward elimination multiple regression analysis method that applied complex sample, to examine the factors related with the finally estimated quality of life. Results: The results of this study revealed that hypertension patients' quality of life was related with age, occupation, spouse, household income, weight gain, restriction of activity, subjected health status, perceived stress, and presence of comorbidity. The final model explained 37.0% of the variance (Wald F=30.012 p<.001). Conclusions: When an intervention program is implemented for the improvement of hypertension patients' quality of life in the future, it will be effective to construct the program according to age group, employment, marital status and household income. As for the program operation, patients should get help therefrom to control weight, facilitate activities and relieve their stress, and they should be also motivated to feel healthy. Furthermore, education should be offered so that they appropriately manage their underlying disease at an early stage.

The aim of this study is to analyze the current status and performance evaluation systems of faculty in Korean medical colleges and professional graduate medical schools (called medical schools). We developed a research tool based on previous studies and distributed it to 40 medical schools from July to October 2017. The response rate was 100%. We calculated the number of faculty members and analyzed the faculty evaluation systems and awareness according to national and private medical schools. As of 2017, the number of medical faculty in Korea was 11,111 (4,973 faculty were employed by their alma mater, which is 44.76% of the total), with non-medical doctor faculty accounting for 754 of the total. The medical schools reflect research achievements as most important for re-appointment and screening to promote faculty, and the area of education is secondary excepting clinical faculty of private medical schools. However, important issues in the faculty evaluation deal with the relevance of research achievement and the need for qualitative assessment. Some medical schools revised or have been revising the faculty evaluation system in areas such as minimum standards of education for promotion and separation of promotion and tenure review. Opening non-tenure track lines for faculty show positive effects such as increasing the number of positions for hire and easing the financial burdens of medical schools. Downfalls include inconsistencies between the responsibilities and actual practices of tenure not being available and the instability of faculty's status. In conclusion, medical schools need to prepare a faculty evaluation system that fits the position of faculty members and attempt to establish a reasonable compensation system.

Purposes: This study aimed to identify relevant factors that determine cancer surgery at a medium-sized general hospital where patients are diagnosed with cancer. Methodology: The study subjects were 1,530 patients diagnosed with cancer between November 2013 and October 2019 at a 400-bed general hospital located in the metropolitan area. Multiple logistic regression analysis was performed to identify the patient characteristics, cancer types, and characteristics of treatment experience of the study subjects, in addition to the determinants of cancer surgery in the hospital. Findings: Among 1,530 cases diagnosed with cancer, 353 cases (23.1%) were operated at the hospital where the cancer diagnosis was made. As determinants of surgery after a fist-time diagnosis at a general hospital, the likelihood of having surgery at the hospital, for colorectal cancer patients compared to stomach cancer patients (Odds Ratio=2.38), bladder and kidney cancer patients (Odds Ratio=1.79). According to the results of an additional survey conducted, it was found that important determinants of decisions on a hospital to receive cancer surgery were the kindness of the staff including doctors and nurses, and the trust in the medical skills and technique of the doctor. Practical Implication: The management of general hospitals should take note of the fact that it is important to establish proactive strategies for hospital management including strengthening the rapport between patients and medical institutions based on the kindness of medical staff (doctors and nurses) and staff, in addition to promoting cancer adequacy evaluation results and introducing one-stop systems.
