  • This paper presents a new image retrieval method that is based on color space and block region information. The color space information of images can be obtained by color binary set, and the block region information can be obtained by regional segmentation and feature. The candidate images are decided by comparing with color features and its binary set of query image and image feature database for retrieval. Particularly, it is possible that the retrieval using similarity-measurements has the weights of color spatial distribution arid its objective block region features. This retrieval method using color spatial and block region features is shown with the effectiveness on the result of implementation on image database with 6,000 images.

  • Most neoplasm of the floor of the mouth are squamous cell carcinoma. They originate from anterior midline floor of the mouth and penetrate into the sublingual gland. Invasion of the mandible is a late manifestation. Lymphatic spread is the submaxillary and subdigastric nodes and advanced lesions of them produce severe pain, The initial step in managing patients with cancer pain is the oncology therapy in the form of radiotherapy, surgery, or chemotherapy, alone or combined. When oncologic therapy is ineffective, the pain must be treated by systemic analgesic, psychologic, neurostimulating, regional analgesic,and meuroablative techniques. We successfully treated with gasserian ganglion block on the left side and mandibular nerve block on the right side with pure alcohol in the patient having severe submandibular, lower lip and tongue pain.

  • The most widely used method of pain control in dental practice is to block the pathway of painful impulses by local anesthesia. For a maximum effect of pain control at outpatient minor operation, regional anesthesia including nerve block must be performed. This issue includes various dental local anesthetic techniques on mandible, maxilla and considerations for selection of dental local anesthetics according to patient's age, duration of operation. Additionally, current conscious sedation technique combined with local anesthesia will be introduced for control of patient's anxiousness. Based on patient's general condition, severity of operation, local anesthesia sometimes must be changed into general anesthesia to avoid failure of dental practice. The exact choice of anesthetic techniques for minor operations at dental outpatient clinic must not be underestimated for complete success of pain control.

  • This study is about architectural design for rural housing block redevelopment for districts with existing residents considering sustainable development. The study suggests development direction focusing on preserving the regional characteristics, and presentation of suburban-style housing complex reflecting on the future tenant's individuality and demand. The preexisting development approach for suburban-style housing complex which was planned by the developer, failed to recognize taste of the future tenants. Profitability being the priority, it also resulted in a serious environmental disruption. In this development however, through a systematic direction for site development and site analysis, conducting surveys through future tenants, attempted for a continuous growth of the community. The study is presented covering the following areas; site's pathway system, nature conservation plan, lot plan, land use, arrangement plan, housing plan and community facility.

  • Stellate ganglion block is a well established method for the management of certain pain syndromes (e.g., chronic regional pain syndrome, facial pain) in the cervicothoracic region and upper extremity. The stellate ganglion resides between the C7 transverse process and the head of the first rib. Anesthetic injections for the stellate ganglion block are typically made at the level of the transverse process of either the C6 or C7 vertebrae to avoid the pleura, vessels, and nerve roots. Method of positioning the needle tip directly at the ganglion has been described, but are problematic because of the risk of injury to or injection into adjacent structures. It is necessary to know the exact anatomic position of the stellate ganglion when permanent blockade is required by means of radiofrequency thermocoagulation. Whereas fluroscopy shows only bony feature, computerized tomography also images nerves, vessels, and lung, allowing accruate needle placement. We report a case of the percutaneous radiofrequency thermocoagulation of the stellate ganglion after computerized tomography-guided localization.

Ultrasound-guided Nerve Block for Skin Grafting on Large Diabetic Ulcer of Foot and Leg: A Technical Report (광범위 당뇨병성 족부 및 하퇴부 궤양의 피부이식술에 사용된 초음파 유도 신경 차단: 술기 보고)

  • Skin grafting is often required for diabetic ulcerative foot lesions. In skin grafting, effective regional or local anesthesia into the donor and recipient areas plays a significant role in continuous control of pain. We report on a technique of ultrasound-guided nerve block on the femoral, sciatic, and lateral femoral cutaneous nerves in large split-thickness skin grafting for ulcer of the foot and leg.

  • Orofacial pain is a common complaint of patients that causes distress and compromises the quality of life. It has many etiologies including trauma, interventional procedures, nerve injury, varicella-zoster (shingles), tumor, and vascular and idiopathic factors. It has been demonstrated that the sympathetic nervous system is usually involved in various orofacial pain disorders such as postherpetic neuralgia, complex regional pain syndromes, and atypical facial pain. The stellate sympathetic ganglion innervates the head, neck, and upper extremity. In this review article, the effect of stellate ganglion block and its mechanism of action in orofacial pain disorders are discussed.

  • A 20-year-old male patient developed severe right leg pain, hyperesthesia and allodynia after multiple lumbar epidural blocks. His pain was neuropathic pain (complex regional pain syndrome type I). The patient was treated with repeated administration of epidural ketamine at the rate of 0.2~0.7 mg/kg on multiple occasions. Complete relief of pain was achieved.

  • This article presents a case report of complex regional pain syndrome (CRPS) involving the ankle and foot; the bee-venom herbal acupuncture (BVH) was performed as part of a pain management program. An 46-year-old man presented with CRPS in the left lower extremity that was inadequately controlled with typical oral medication. Sympathetic block the extremity did not provide significant pain relief. However, BVH resulted in significant pain relief and improvement in patient's attitude. This case report showed that BVH may be efficacious in treating patients with CRPS. Further study is needed to determine the effects of BVH on symptoms related to CRPS.

  • The pathomechanisms involved in both restless legs syndrome (RLS) and complex regional pain syndrome type I (CRPS I) are still controversial whether they are central or peripheral origins. We recently encountered a patient who had an unusual coexistence of both RLS and CRPS I, and both of which showed good responses to sympathetic block. These findings suggest the role of peripheral mechanisms, especially unmyelinated small autonomic fiber, in both RLS and CRPS I.
