  • Anterior knee pain syndrome would best be defined as a painful condition that arises in or around the patellofemoral joint and is insidious in onset and bilateral, with an enigmatic entity with multiple causes. Although its etiology is uncertain, the cause is often considered to be abnormal lower limb biomechanics, pathology of extensor mechanism, disorder of patellofemoral joint, malalignment or lateral tracking of the patella, soft tissue tightness, muscle weakness. The measurement of patellar alignment has come to be accepted as an integral part of the examination of anterior knee pain syndrome. Various measurement techniques exist, both clinical and radiological, and these have been frequently used in the diagnosis and treatment of the condition.?Treatment depends on the underlying cause of anterior knee pain and should be directed to the cause rather than to the results. Most often, this involves non-surgical measures, such as anti-inflammatory medications, quadriceps exercises, and hamstring stretching. Shin splint, or medial tibial stress syndrome refers a syndrome of pain running along the inner distal 2/3 of tibia shaft. Shin splint is a common problem for athletes whose sport involves a repeated, jarring impact to the leg. A major factor determining the efficacy of the treatment is that correct diagnosis be made of the problem. The varied etiology has led to the development of several theories as to the cause, treatment, rehabilitation and prevention of shin splint. The management is rest, ice massages, pain relief by medication, and muscle strengthening exercise. Proper rehabilitation and preventative measures can ensure that there is no further recurrence.

  • This study was directed at the design of a hybrid algorithm for competition relation extraction. Previous works on relation extraction have relied on various lexical and deep parsing indicators and mostly utilize only the machine learning method. We present a new algorithm integrating machine learning with various filtering methods. Some simple but useful features for competition relation extraction are also introduced, and an optimum feature set is proposed. The goal of this paper was to increase the precision of competition relation extraction by combining supervised learning with various filtering methods. Filtering methods were employed for classifying compete relation occurrence, using distance restriction for the filtering of feature pairs, and classifying whether or not the candidate entity pair is spam. For evaluation, a test set consisting of 2,565 sentences was examined. The proposed method was compared with the rule-based method and general relation extraction method. As a result, the rule-based method achieved positive precision of 0.812 and accuracy of 0.568, while the general relation extraction method achieved 0.612 and 0.563, respectively. The proposed system obtained positive precision of 0.922 and accuracy of 0.713. These results demonstrate that the developed method is effective for competition relation extraction.

  • Increase in the wireless mobile network users brings the issue of mobility management into the Virtual Private Network (VPN) services. We propose a provider edge (PE)-based provider provisioned mobile VPN mechanism, which enables efficient communication between a mobile VPN user and one or more correspondents located in different VPN sites. The proposed mechanism not only reduces the IPSec tunnel overhead at the mobile user node to the minimum, but also enables the traffic to be delivered through optimized paths among the (mobile) VPN users without incurring significant extra IPSec tunnel overhead regardless of the user's locations. The proposed architecture and protocols are based on the BGP/MPLS VPN technology that is defined in RFC24547. A service provider platform entity named PPVPN Network Server (PNS) is defined in order to extend the BGP/MPLS VPN service to the mobile users. Compared to the user- and CE-based mobile VPN mechanisms, the proposed mechanism requires less overhead with respect to the IPSec tunnel management. The simulation results also show that it outperforms the existing mobile VPN mechanisms with respect to the handoff latency and/or the end-to-end packet delay.

  • Type II membranoproliferative glomerulonephritis (Dense deposit disease) is an acquired primary glomerular disease characterized by electron microscopic evidence of a continuous dense membrane deposition replacing the lamina densa. It is a subtype of idiopathic membra- noproliferative glomerulonephritis, and was described as a separate entity by Berger and Galle in 1963. It frequently occurs in older chilren and young adults and the clinical course is variable, but is generally progressive. The presenting feature is nephrotic syndrome in many patients, and proteinuria and hematuria are also seen frequently. The purpose of this paper is to present a case of DDD (Dense deposit disease) from a 10 year old boy who was diagnosed as a acute poststreptococcal glomurulonephritis with protenuria, hematuria, and facial edema by renal biopsy 4 years ago.

  • Bronchoesophageal fistula is a rare clinical entity whether congenital or acquired in adult. We experinced 8 cases of bronchoesophageal fistula and performed surgical correction from 1991 to 1994. Of the 8 patients, 5 patients were male and three were female aging from 21 to 61 years(mean 44.12$\pm$14.62 years). Seven of 8 patients had congenital bronchesophageal fistula and the other one had acquired bronchoesophageal fistula. According to the classification of Braimbridge and Keith, 4 cases were belonged to type I and 3 cases were type II . The diagnosis was confirmed by esophagogram in six patients, by bronchoscopy and bronchogram in two patients, and in one patient, the fistula was discovered i cidentally during operation. All patients received astulectomy and concomitant procedures were applied as follows ; 4 diverticulectomy, 4 right lower lobectomy, 1 bilobectomy, 1 left lower lobectomy and 1 wedge resection of left lower lobe. All but one patient were discharged without any complication and have been in good condition.

  • All excavated "buried cultural properties" are supervised by the Cultural Heritage Administration that decides whether to conserve them or not, depending on the necessity for conservation. Currently, there is no legal regulation concerning the administration of relics (including artifacts) and remains (including archaeological sites) that are relocated and restored based on such conservation decisions. Thus, administration of these cultural properties is inadequate. Under these circumstances, this paper recommends the current state of conservation and conservation methods for buried cultural properties excavated at Chungcheongnam-do thus far. Conservation of buried cultural properties excavated at Chungcheongnam-do primarily employ the "relocating and restoration" method; 23 relics and 46 remains employed relocation after dismantling and soil layer transcription method. Moreover, 27 remains were relocated after dismantling and 14 remains employed the transcription method. In terms of area, Buyeo-gun and Gongju-si had 12 relics accounting for about 50%, while according to the period, Baekjae period had 16 relics, accounting for about 70%. In terms of conservation facility, open-air facility had 33 relics, accounting for about 72%. Results of investigating the state of relics' management indicated that public institutions like a museum with a recognizable management system had their own work force and consequently ensured excellent conservation, whereas if there were no apparent responsible bodies, remains were subjected to considerable damage due to mismanagement. Therefore, this problem can be resolved by identifying a recognizable management body as well as ensuring periodical management and supervision. The excavated buried cultural properties are utilized not only for academic purposes, but also for PR or as exhibition material. Hence, this study confirms that meticulous management of buried cultural properties is currently required.

  • It is impossible that the corporation can make up good corporate images with sales promoting and pursuing profits only. To form impressive oorporate images, the corporation should acquire efficient marketing images and social oonfidences with the investment for the culture, the art, the preservation of public health, educations and social welfare programs. The oorporate image is indined to be formed by audiences subjectively even though the corporation makes great efforts to have its unique images. The audience has a tendency to have their subjective opinions about the corporate image based on several informations communicated by the corporation and various sources. The sensitive approach and emotional persuation can be efficient for making good corporate images because corporate images of audiences arise from emotional and sensitive factors rather than rational ones. There are many previous studies verifying that the humor effect should be one of powerful means for inducing concentrations, memorizations and persuations. The majority of popular advertisings are humor touched one and the questionaire proves that almost all university students participating sample test, prefer humorous advertisings to serious advertisings. The questionaire verifies that it is a most efficient method is using humor effects at product advertising to improve the corporate image indirectly. And there are very possitive reactions about applying humor effects for the corporate image advertising and the other advertisement types such as pamphlets and catalogues. The humor effect motivates the persuation with spiritual pleasures and intimacy, and it minimize the negative aspects of advertising for the formation of the corporate image. The humor effect is valuable not only for the formation of the corporate image reflecting the entity of the oorporation itself but also for the ideation of advertising communications. The study on the humor effect related with the corporate image is significant because the humor is a different version of the humanism based on deep oontemplation and oomprehension of human life rather than simple means to motivate laughers.

  • Purpose: To report our experience with nine cases of pathologic synovial plica on radiohumeral joint which symptom of painful snapping elbow was improved by arthroscopic resection. Materials and Methods: Between 1999 and 2004, 43 cases of elbow arthroscopy were performed by one surgeon. Eight patients with nine cases showed pathologic synovial plica in conjunction with snapping or posterolateral elbow pain. The mean age of eight patients (man: 7, woman: 1) was 29 years (range $16{\sim}56$ years). All patients had a trial of conservative treatment at least six months (range $6{\sim}16$ months). The diagnosis was confirmed before surgery in six cases and at the time of surgery in three cases. Pain, snapping, and subjective results were evaluated at least 12 months in the average(range $12{\sim}24$). Results: All patients showed a hypertropic lateral synovial plica with local synovitis. Seven of them had an associated lesion of chondromalacia on radial head. One of them was associated with radiocapitellar arthritis and had a wrapping over the radial head. Six patients experienced improved posterolateral pain at the end of study (VAS<1). However, the other two patients had occasional pain with activity. One of them persisted with mechanical symptoms, which was treated with additional arthroscopic procedure. Conclusion: Synovial plica in elbow should be considered as an important entity of common elbow disease, especially when pain in the lateral aspect of the elbow with a snapping sensation during motion is featured in patients. The arthroscopic resection seems to be safe and efficient in the short and long term treatment of plica in the elbow joint.

  • Mobile e-business is in wide use with the rapid growth of wireless internet users. To meet the growing requests for mobile e-business the productivity of mobile applications has been demanded. The WAPSiteGen, introduced in this paper, automatically generates a 3-tier WAP application that needs a new application database or that already has an application database to increase the productivity. The WAPSiteGen generates the EJB components that handle business logic and the JSP Web components that process user-made queries and the WAP Push feature. For a presentation layer, it also generates the HTML forms for an application manager and the WML decks for end users, which consists of many cards. The WAPSiteGen enhances extendibility, reusability and portability of generated 3-tier applications by comprising such component technologies as EJB and JSP. Furthermore, it supports the WAP Push services for generated applications that provide necessary information to wherever and at whenever a user wants. Since the applications generated by the WAPSiteGen provide the information on an interested entity as well as the information on all the directly or indirectly related entities to the interested one, it shows faster information accessibility. In this paper, we explain the functionality and implementation of the WAPSiteGen and then show its merits by comparing the WAPSiteGen to commercial WAP application generators.

  • A burnt-out prostate cancer tumor is a very rare clinical entity. The term 'burnt-out' refers to a primary tumor that has spontaneously and nearly completely regressed without treatment. Since metastasis of prostate cancer is usually encountered in the presence of advanced disease, distant metastasis with an undetectable primary tumor is very rare. We report herein a case of a burnt-out prostate cancer tumor that metastasized to the thoracic (T) spine and caused cord compression. A 66-year-old man visited the Emergency Department due to weakness of both legs for the past two days. His blood and urine tests were normal at the time. His spine magnetic resonance imaging (MRI) scans looked like bone metastasis that involved the T-7 vertebral body and a posterior element, and caused spinal cord compression. Other images, including from the brain MRI, neck/chest/abdomino-pelvic computed tomography (CT) scan and 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) and endoscopy, revealed no lesions that suggested malignancy. After total corpectomy T-7 and screw fixation/fusion at T5 to T10, the pathology report revealed a metastatic carcinoma that was strongly positive for prostate-specific antigen (PSA). The serum PSA value was 1.5 ng/mL. The transrectal 12-core prostate biopsy and ultrasonography showed no definitive hypoechoic lesion, but one specimen had slight (only 1%) adenocarcinoma with a Gleason score of 6 (3+3). The final diagnosis was burned-out prostate cancer with an initial normal PSA value. Although metastatic disease with an unknown primary origin was confirmed, a more aggressive approach in seeking the primary origin could provide a more specific treatment strategy and greater clinical benefit to patients.
