The National Education Information System (NEIS), one of ERP systems developed by Ministry of Education & Human Resources Development, has been utilized in primary and secondary schools. In this paper, we considered the NEIS should be used not only for educational administration affairs, but also for a lifelong management of National Human Resource. The current School Information Management System (SIMS) is unsatisfactory due to the insufficiency of actual field suitability and user's conveniency. For solving such problems, the system rebuilding or revision should be accompanied by. As a guideline of revision and supplement of the SIMS, we suggest an application useful in both schools and clinics by the integrating healthcare management information of people. For this, we propose a lifelong healthcare information management by integrating Student Health Records of the NEIS with Electronic Medical Records of doctors' offices. The healthcare information is designed and represented in XML. We applied different XSL style-sheets to XML documents in order to offer a view suitable for demands of schools and clinics. The healthcare information can be managed and utilized efficiently by using the view. We ascertained that the lifelong Healthcare Information Management System is an improvement to overcome the inefficiency of healthcare information management and the connection inadequacy between schools and medical institutions, and is desirable for a lifelong management of the National Human Resource.

Although the value of technology is evaluated by various methods, the result of technology valuation is different from evaluator and evaluation methods. Also the uncertainty on the result occurs with respect to the evaluation factors and evaluation model which should be considered. In the case of lack of data or comparison target, the credibility of the technology valuation result could be unsure. To decrease uncertainty of the technology valuation, Fuzzy concept and Fuzzy Comprehensive Evaluation method are applied instead of using existing methods which evaluate technology value(level) by the number. In the research, we firstly devide evaluation criteria into technology value factor and business value factor and evaluate the technology level for micro pressure wave reduction technology which has been developed in Korea. Technology value factor is marked as high level with 46%, and business value factor is very high with 44%, and the overall level of technology is evaluated between very high and high. It helps to compare to other technology in the rivalry by the factors as it can evaluate the value of technology by factors. The technology valuation method which is applied in this research is expected to use on analyzing technology level of new technology or alternative technology in many different field.

Purpose: To evaluate the differentiation potential of stem cells and their immunophenotype from 3 different sources. Methods: Our study involved three stem cell sources-subacromial bursal tissue, bone marrow, and umbilical cord blood. We obtained the subacromial bursal tissue and bone marrow from the patients undergoing shoulder surgery. After collecting the sample, we applied specific induction media for neurogenic, adipogenic and osteogenic differentiation. Also, flow-cytometry analysis was done to reveal the cell surface antigens. Results: We obtained 100% (8 cases) neural and adipogenic differentiation, but 62.5% (5 of 8 cases) osseous differentiation among the subacromial bursal tissue group. Bone marrow derived cells showed 100% neural (6 cases) and adipogenic (5 cases) differentiation, but 80% (4 of 5 cases) osseous differentiation. Umbilical cord blood derived cells revealed 97% (65 of 67 cases) neural, 53.7% (29 of 54 cases) adipogenic and 68.4% (39 of 57 cases) osseous differentiation. Immunophenotype analysis revealed that surface markers of bone marrow, subacromial bursal cell and umbilical cord blood derived mesenchymal stem cells are different from each other. Conclusions: Mesenchymal stem cells are potential agents in regenerative medicine and are characterized by expression of surface markers and by their differentiation potential. Our study with stem cells from subacromial bursal tissue, bone marrow and umbilical cord discovered that each stem cell has unique differentiation potential and function based on its origin. Various stem cells show multi-lineage differentiations in vitro which can be correlated to in vivo conditions.

Purpose: The purpose of this study was to evaluate the results of bioabsorbable knotless suture anchoring for isolated type II SLAP. Materials and Methods: Fourteen patients with isolated type II SLAP underwent a surgical repair with bioabsorbable knotless anchor arthroscopically. Instability, rotator cuff tears or simple subacromial decompression were excluded. The UCLA and pain of VAS (Visual Analogue Scale), ADL (Activity of Daily Living, from the American Shoulder and Elbow Society) were evaluated and patients underwent a thorough shoulder examination at a minimum follow-up period of 2 years postoperatively. Results: At a mean of 27.1 months follow-up. The mean UCLA score improved from 14.4 pre-operatively to 31.2 on last follow-up. The mean VAS for pain was 4.9 and on last follow-up 1.0. The mean VAS for instability was 2.6 and on last follow-up 0.5. The mean ADL was 10.4 and on last follow-up 25.0. 12 patients reported their satisfaction as good to excellent and 10 of the 14 patients returned to their pre-injury level of activity (athletics) (P<0.05). Conclusion: Arthroscopic repair with bioabsorbable knotless suture anchors is an effective surgical technique for the treatment of an isolated unstable type II SLAP lesion. Overall satisfaction was only 85.7%. 1 patient had severe stiffness and 1 patient had shoulder pain.

Purpose: The purpose of this paper is to clinically evaluate the usefulness of all arthroscopic repair with biceps incorporation in massive sized full thickness rotator cuff tears. Materials and Methods: This is a prospective comparative outcome study evaluating a series of all arthroscopic rotator cuff repairs with biceps incorporation on massive(range: $5{\sim}\;cm6$ sized) from March 2003 to May 2006. Group I was twenty two cases of arthroscopically repaired with biceps incorporation, twenty cases of group II without biceps incorporation were analyzed. The average age of the patients was 58 years(range, $41{\sim}74$ years), and mean follow-up was 24 months(range, $12{\sim}36$ months). Results were statistically compared by Mann-Whitney test. Results: Average VAS for pain, ADL, UCLA score were not significantly different between group I and group II (P>0.05 for each). Forward elevation strength was 4.3 in group I, 3.5 in group II(P<0.05). On postoperative follow up ultrasound, retear was 10 cases in the middle of 19 cases at group I, 15 cases in the middle of 17 cases at group II (P<0.05). Conclusion: This study reveals that all arthroscopic repairs with biceps incorporation in massive sized full thickness rotator cuff tears is an effective surgical method and reduced retear and enhanced strength.

Noises can distort acquired geophysical data, leading to their misinterpretation. Potential noises sources include anthropogenic activity, natural phenomena, and instrument noises. Conventional denoising methods such as wavelet transform and filtering techniques, are based on subjective human investigation, which is computationally inefficient and time-consuming. Recently, many researchers attempted to implement neural networks to efficiently remove noise from geophysical data. This study aims to review and analyze different types of neural networks, such as artificial neural networks, convolutional neural networks, autoencoders, residual networks, and wavelet neural networks, which are implemented to remove different types of noises including seismic, transient electromagnetic, ground-penetrating radar, and magnetotelluric surveys. The review analyzes and summarizes the key challenges in the removal of noise from geophysical data using neural network, while proposes and explains solutions to the challenges. The analysis support that the advancement in neural networks can be powerful denoising tools for geophysical data.

As people are more concerned about their health and medical care, there have been an increasing number of medical disputes due to increased medical demand. In order to prevent and provide solution to currently surging medical accidents and disputes related to orthodontic treatment, in July 1998, the Korean Association Of Orthdontists surveyed 2,200 members of Korean Association of orthodontists on 30 items to recognize the pattern of medical accidents and prevent them. The survey was about accident-related items including personal profiles of members and patients who have undergone medical accidents or disputes, the cause and solution to the accidents, cautions related to members orthodontic treatment, and medical recording and archival. Based on the survey result, we analyzed characteristics of medical accidents and disputes in orthodontic area. It is more important to predict and prevent possible medical accidents or disputes based on current situation than to solve them after disputes occur. For this, we should not be negligent in raising treatment proficiency level based on patient-doctor trust and in obtaining new medical information. We should also provide medical environment where Patients themselves can decide whether to get treatment after they are offered detailed explanation on diagnosis, treatment procedure, complication, and possible hazard. We should take caution when treating patients and pay attention to charting and maintenance, which is the most fundamental, as well. Also at the Korean Association of orthodontists level, it is desired to provide education program on prevention and solution to medical accidents and disputes, and actions and organizations that can help when accidents and disputes occur.

This study performed a proprioception improvement training for recurrence prevention of industrial workers with chronic lateral epicondylitis and analysed their pain and proprioception. The subjects of the study were thirty chronic lateral epicondylitis patients working for K company and were divided into elbow exercise program Group made of 15 subjects and proprioception improvement training Group made of 15. As variables for pain, pressure pain, and grip strength were measured and for the propioception, joint position sense of each group was measured before and after the exercise program. To compare differences before and after the program, a paired t-test was used and to compare differences between both groups, an independent samples t-test was used. As a result of the test, it was discovered that pressure pain, grip strength and joint position sense of the both groups were improved statistically significantly. These were statistically differential effect between each group on pressure pain, grip strength and joint position sense. In conclusion, it is suggested that proprioception improvement training should be considered as a method chronic and recurrence prevention lateral epicondylitis of industrial workers.

Purpose: We present a case of anterior glenoid rim comminuted fracture that was treated with arthroscopic reduction and an AO headless compression screw (HCS) fixation. Materials and Methods: A 31-year old man complained of left shoulder pain after falling down on stairs. The anterior glenoid comminuted fragments were arthroscopically reduced. Fixation with an AO HCS was done after placement of 1.1 mm Kirschner wire as a guide pin through a standard cannulated anterosuperior portal. Results: Twelve months after the operation, union of the fracture was achieved and the range of motion was fully recovered. He did not complain of any discomfort during his activities of daily living. Conclusion: An AO HCS had various screw sizes and this was good for fixation of a small glenoid fracture and a long drill bit and screw driver were useful for fixation of deep seated glenoid fracture. A short guide wire could be replaced by a 1.1 mm K-wire. An AO HCS was useful for fixation of an anterior glenoid rim comminuted fracture.

Purpose: To evaluate and compare the results of children with displaced supracondylar fractures of humerus treated with open reduction and pinning with closed reduction and pinning. Materials and Methods: From March 2002, we treated 17 patients with completely displaced supracondylar fractures under the age of 7 with a minimal follow up period of 6 months. 9 patients were treated with closed reduction and pinning and 8 patients were treated with open reduction and pinning. The clinical results were evaluated with Flynn's criteria. Time to bone union was also analyzed for these two set of patients. Results: The group treated with open reduction had 6 excellent and 2 good results for change in carrying angles, 5 excellent, 2 good and 1 fair results for motion loss evaluated by Flynn's criteria. The average time to bony union for this group was 5.8 weeks. The group treated with closed reduction had 6 excellent, 2 good, and 1 fair results for change in carrying angles and 7 excellent, 1 good and 1 fair results for motion loss. The average time to bony uinon for this group was 3.7 weeks. Conclusion: In treating completely displaced supracondylar fractures of humerus in children, the closed reduction method and open reduction method all showed good results. But the operation time, duration of hospital stay and time to union was somewhat shorter for the patients treated with closed redution and pinning.
