본 논문은 효율적인 영상처리를 위해 방향성 정보를 개선한 이중 트리 컴플렉스 웨이브렛에 관한 연구이다. 이중 트리 컴플렉스 웨이브렛 변환은 이동 불변 성질을 만족하며, 기존 이산 웨이브렛 보다 많은 6개의 방향성 정보를 포함한다. 하지만 간판, 건물과 같은 구조물의 경우 수평 수직 방향 에지 성분들이 많이 포함되어 있어서 6개의 방향성 부대역으로만 영상의 고주파 성분을 모두 표현하기에는 부족하다. 따라서 기존 이중 트리 컴플렉스 웨이브렛 변환의 6개 방향성 부대역 외에 수직 수평($0^{\circ}$, $90^{\circ}$) 부대역을 생성함으로써 우수한 고주파 분리 특성을 갖는 8방향 컴플렉스 웨이브렛 변환 방법을 제안한다. 본 논문에서는 영상의 특성에 따라 다양한 방향성 성분 부대역 생성이 가능하며, 대표적 응용분야인 잡음제거에 활용해 봄으로써 성능을 평가한다.

Objectives : This study reports the clinical case of a patient diagnosed with ossification of the posterior longitudinal ligament treated with Korean Medicine focusing on Chuna therapy. Methods : The patient was treated by a doctor from July 18th, 2019 to November 28th, 2019. The patient was diagnosed with ossification of the posterior longitudinal ligament based on magnetic resonance imaging results and was recommended to undergo surgery at another hospital. The primary complaint of the patient was left neck pain, left arm sensation, right leg sensation, and right leg loss of strength. The doctor treated the patient with Chuna therapy, acupuncture, cupping, herbal medicine, and pharmacopuncture. The effect of treatment was evaluated using visual analogue scale, neck disability index, pain rating score and Japanese Orthopedic Association score. Spurling, compression, and distraction tests were utilized. Results : Visual analogue scale decreased from 10 at the arm and 10 at the leg to 1 and 2, respectively. Neck disability index decreased from 25 to 11, pain rating score decreased from 66 to 1, and Japanese Orthopedic Association score recovered from 12 to 17 points. In addition, positive spurling test, compression test, and distraction test all improved to negative. Conclusions : Korean medicine treatment can be effective for ossification of the posterior longitudinal ligament patients, even when surgery is recommended. Further clinical studies, such as case series and case-control studies, are required to verify these findings.

Objectives : Herniated lumbar intervertebral disc (HIVD) is one of the cause of low back pain and radiculopathy. To evaluate the efficiency of simultaneous administration of herb medicine and non-steroid-anti-inflamatory drugs (NSAIDs), we investigated 48 HIVD patients confirmed by CT or MRI and treated with acupuncture, bed rest, herb medicine, physical therapy and NSAIDs. Methods : The patients were divided into four groups as follows : The A group were 11 cases treated with only herb medicine A. The A+W group were 14 cases treated with herb medicine A and NSAIDs. The B group were 11 cases treated with herb medicine B. The B+W group were 12 cases treated with herb medicine Band NSAIDs. We evaluated the pain degree by visual analog scale (VAS). Results : The mean VAS was reduced to $4.89{\pm}2.62$ after 2 weeks therapy and pain decrease was the most prominent in the group having within a week duration ($3.25{\pm}2.49$). Pain scale was decreased to $4.57{\pm}2.95$ in A+W group, $4.91{\pm}1.97$ in A group, $4.72{\pm}2.68$ in B group, and $5.41{\pm}2.67$ in B+W group after 2 weeks therapy. Conclusions : These results indicate that oriental medical theraphy is useful enough to treat the HIVD patients and herb medicine decrease the pain of the HIVD effectively. Therefore, the more research about herb medicine for pain killing drugs should be done.

Objectives : Among the various types of minimally invasive spine surgeries, thoracoscopic surgery is becoming more widely accepted and increasingly utilized. This report delineates our clinical experience using thoracoscopy to resect herniated thoracic discs in 16 patients who suffered from myelopathy or intolerable radiculopathy. Patients and Methods : Between Mar. 1997 and Sep. 1999, 16 consecutive patients underwent thoracoscopic discectomy for treatment of herniated thoracic discs. There were 12 men and 4 women(mean age 43.5 years ; range 18-61 years). Eleven patients presented with myelopathic signs and symptoms from spinal cord compression and 5 patients had incapacitating thoracic radicular pain without myelopathy. The surgical level was varied between T3 and T12. The pathology of specimen were 11 hard discs and 5 soft discs herniations. Thoracoscopic techniques were performed with long narrow spine instruments and high speed drill through 3 or 4 ports under one lung ventilated general anesthesia. During the operation three patients were converted to open thoracotomy due to intolerable one lung ventilation, excessive bleeding and inadequate operation field. The mean operation time was 264min.(range : 100-420min.), and postoperative mean admission period was 11 days. Results : Clinical and neurological outcomes were good in all patients(mean follow-up period 20 months). Among the eleven myelopathic patients, 8 improved neurologically, and 3 stabilized. Among the five radiculopathic patients, 4 recovered completely and no patient had worsened. Postoperative complications were pleural effusion in one case, intercostal neuralgia in one, delayed hemopneumothorax in one, prolonged air leakage in one and pneumonia in one case. Conclusions : Thoracoscopic discectomy needs a steep learning curve to be familiar to anatomical space and handling of endoscopic instruments. However, it is technically feasible and can be effectively performed with acceptable results.

본 연구의 목적은 척추감압치료와 한의학적 치료법으로 치료된 요부디스크 탈출 6례에 관한 자기공명영상의 변화를 보고하는 것이다. 디스크 높이는 $T_2$-강조 자기공명영상의 시상면으로 측정되었다. 탈출된 디스크의 크기는 MRI와 디스크 탈출지수로 측정되었다. 디스크퇴행에 관한 등급체계와 연산은 MRI 신호강도, 디스크구조, 수핵과 섬유륜의 구별을 기초로 하였다. 디스크 높이, 디스크 탈출지수와 디스크 변성등급은 MRI로부터 측정하여 치료 전과 후에 수집되었다. 본 증례연구가 보여주는 것은 디스크 탈출에 대한 감압치료가 디스크 높이를 제외한 디스크 탈출지수, 디스크 재생에 긍정적인 영향을 미친다는 것이다. 디스크 탈출에 대한 감압치료의 사용에 관한 임상적 증거는 제한된 연구 때문에 미비하다. 따라서 이 분야에 주의를 기울이기 위한 더 많은 시도들은 명확한 결론을 내리기 위해서 필요할 것으로 사료된다.

Unlike other types of outdoor advertisements, rooftop signboards are installed on the roofs of buildings, rather than on their outer walls. This means that the area of a rooftop signboard is commonly larger than that of a general outdoor signboard. Moreover, as such signboards are greatly influenced by the wind, they can suffer a lot of damage from typhoons and strong winds every year. However, there is no wind load specification for rooftop signboards. In this study, wind pressure experiments were conducted to investigate the peak wind pressure on each side of rooftop signboards installed on the roofs of 5-15 story buildings in a city center. The minimum peak wind pressure coefficient was -3.0 at the bottom edges of the front and back of the rooftop signboards and -2.0 along the entire length of the sides. As the height of the rooftop signboard increased with the increasing height of the buildings, the peak value was found to be larger than the absolute peak value for the minimum peak wind pressure coefficient. The maximum and minimum peak wind pressure distributions of the rooftop outdoor signboards were influenced by the position of the signboard and the wind angle.
